ARSC Announces Open Research Systems Status
ARSC is pleased to announce a change in the center's account application process.
All High Performance Computing Modernization Program (HPCMP) resources at ARSC are now "open" research systems. This includes "klondike," the Cray X1 and "iceberg," the IBM Power4 Cluster.
With this change, potential users are no longer required to have a National Agency Check (NAC) when applying for an account. In particular, this change is expected to simplify the application process for UAF researchers and foreign nationals. Users are required to provide proof of citizenship (and current visa, if applicable) and consent to routine standard background checks in lieu of a NAC.
Fall Training: Hands-On Sessions + On-Call Experts
In all the excitement about 10-year anniversaries and 300th issues, I forgot to tell you something of actual importance. ARSC's Fall Training is already under way, with a new format:
- Tuesdays: Hands-on session and lecture on specific skills
- Thursdays: "Working Thursdays": ARSC Expert will be on-call in a lab
Next two skills sessions:
Location: West Ridge Research Building (WRRB), Room 009 Time: 1pm-2pm
- Tuesday, Oct 26: "Cray Quick-Start"
- Tuesday, Nov 2 : "IBM Quick-Start"
Next "Working Thursday":
ARSC Classroom (WRRB 009); 1:00 pm - 5:00 pm
- Thursday, Oct. 28,
X1 Default PrgEnv Updated
On 10/21/2004 at 6pm Alaska time we updated the default programming environment, "PrgEnv," from PE 22.214.171.124 to PE 18.104.22.168. This makes some bug fixes and performance enhancements available to those who use the default programming environment.
The programming environments are now configured as follows:
- PrgEnv.old : Unchanged: points to PE 5.1
- PrgEnv.52.first_set : Unchanged: points to the previous default PrgEnv (PE 126.96.36.199)
- PrgEnv : The current default: PE 188.8.131.52
- PrgEnv.new : Unchanged: points to PE 22.214.171.124
To switch your environment to PrgEnv.old, you would issue the command: module switch PrgEnv PrgEnv.old
For more on programming environments and "module" commands read "news prgenv", "man module", or contact email@example.com.
Book Review: Cogwheels of the Mind: The Story of Venn Diagrams
[ Another thank-you to Guy Robinson, who just had a big birthday! ]
Cogwheels of the Mind: The Story of Venn Diagrams, A.W.F. Edwards, John Hopkins University Press, ISBN 0801874343.
Many folks may remember Venn diagrams from their school mathematics classes as a way to present information about sets or classes and how they intersect. "Cogwheels of the Mind" is the story of these curious objects and their creator, 19th century logician John Venn. It expands on the idea with some recent contributions by the author, A.W.F. Edwards.
One problem with Venn diagrams comes when trying to display the relationships of more than a few sets. After five sets it becomes increasingly difficult to draw simple Venn diagrams with only one region for each relationship.
The book reviews the history of Venn diagrams, many of which show that science and art can come together. Edwards has devised a solution, the "cogwheels" of the title, which is elegant and permits the continued use of Venn style diagrams to high numbers in a systematic manner. Sadly a simple text review cannot capture both the ease and beauty of the various Venn diagrams within the book.
Anybody faced with the display of the relationship of complex data will find ideas within this book useful.
Loupe Performance of the Cray X1: Part II
[ Thanks to Lee Higbie for another chapter... ]
We have been cocksure of many things that are not so. -- Oliver Wendell Holmes
The hardly Holmesian detective Lytton, alias Snoopy, has been investigating the performance of Klondike. While conspiracy might improve the narrative, the vagaries of hardware offer more plausible explanations. The vic, who was sometimes called X1, had a data memory hierarchy with three levels: several sets of registers, a pound of cache, and a stere (kiloliter) of memory. How these are used or exploited has a major impact on system performance and forms the crux of this part of the mystery he was trying to solve.
The performance on the simple set of loops shown in Newsletter 301 could be slowed to about 3% of their good speed by injudiciously using the memory system. Some might call this a crime of conspiracy, or incompetence, but another interpretation seems more likely--a crime of blindness. The performance of any real program is difficult to analyze. Many forensic geekologists have been trained to look at the compiler's information. By compiling with "ftn -rm" and "cc -h list=m", Snoopy was able to dump a loopmark listing to a .lst file. There the legend told him that a "C" meant the loop had been Collapsed, "M" meant Multistreamed, "V" meant Vectorized, and "w" meant unwound. "Aha. You're lucky, Lytton," he said to himself, "You're onto the nexus now."
In this performance investigation, the compiler said it "M'd" the outside loop in both cases. The middle loop was "C'd" in the fast case. The inner loop was "V'd" for the fast loops and "Vw'd" for the three-percenters.
With such a wide disparity, it's tempting to think that Vectorizing is good and Vector-unWinding is bad. "I guess the compiler isn't trying to heal loops," he mumbled. But there were loops with intermediate performance that were only "Vw'd" on the inner loop (nothing on the outer or middle ones). Snoopy figured that Multistreaming and Collapsing were red herrings, also. "The difference seems to be due to the efficient use of the memory in the fast case, which Snoopy called the 'Case of the Klondike Rush,' and its poor use in the slow case, the 'Case of the Chilkoot Trudge.'" But any Cheechako could see that vectorization was necessary, even if not sufficient.
Aha, "The Cheechako Crawl" is when there is no multistreaming or vectorization and the memory system is poorly used. And the slowest crawling is when the loops were coded in the C Language. It's becoming clearer, C is not the culprit but is certainly not a good guy. Like a hostile witness, C has to be pushed in the right direction. Left to its own devices, C would sometimes crawl along at a fraction of 1% of the speed of the fast Fortran loops. Now Snoopy Lytton was in a position to formulate the moral for this chapter.
Short Strides are Swift. Fortran for Fast. C can crawl.
To Google, or not to Google...
[ Thanks to Shawn Houston. ]
As an introduction, and to explain why I am writing this article, I am an ARSC User Consultant. So what does that have to do with Google?
ARSC's public web, www.arsc.edu, hosts all of the information an ARSC user, possibly you, needs to access and best use our systems. As a User Consultant, it is important to me that this information is readily available. Additionally I am the ARSC Webmaster, making me more than a little responsible if you can't find what you need.
It has been brought to my attention that people are using Google to search ARSC's web site. I have nothing against Google and I happen to use the Google search service on a daily basis to do my job, or to find deals, or for a thousand other things that I just need to know. Google works, as do many other search services out there.
Now my point. ARSC's public web site has its very own search facility.
At the bottom of every page is a link that will take you to this simple tool for searching our site. Now, Google is anything but simple and has made a fortune selling its deserved image as the best search engine on the planet. But we have an advantage over Google. The ARSC search tool was built with ARSC in mind. Let's take a look at some features:
- Database updated within one hour of website update
- Word-based search
- Partial word-based search (where 'cat' matches both cats and catalog)
- String search (matches string exactly to text in web page)
- Case sensitive search option (sometimes case does matter)
- Advanced boolean search option
We beat Google on speed and freshness. Google is fast, and caches our web site on a regular basis, but far less than once an hour.
Here's a plunge into the details of the advanced boolean search option. (If you'd like to experiment as you read, the search tool is at: http://www.arsc.edu/cgi/search.cgi .)
Literal strings are entered by using doubles quotes to surround your search terms. This flags the input as literal, spaces and all. This is the least likely search to succeed, but there are times when this is exactly what you want. Boolean search uses the following logical operators to sort your search terms:
- "and" is represented by an ampersand, '&', or the word 'AND'
- "or" is represented by a plus sign, '+', or the word 'OR'
- "not" is represented by an exclamation point, '!', or the word 'NOT'
(The "and," "or," and "not" operators can be given in upper or lower-case.)
To use the boolean search facility you probably want to stick with whole word searches. As an example, suppose I am looking for fortran compiling information for the IBM P655+/P690+ cluster. I do not want to see any Cray system pages, nor do I want to see information about the P690 system, iceflyer, even though it might help. I am only interested in iceberg. Try this search string:
fortran AND compiler AND NOT klondike AND NOT yukon AND NOT Cray AND NOT iceflyer OR iceberg
This yields 22 pages, of which the first is the introduction to the IBM P655+/P690+ cluster, iceberg.
Lets take the search input apart. The default search is not case sensitive and is word based, so we are looking for whole words only, not partial word matches. The first two key words are what we are searching for, "fortran compiler." We add the key word AND between the words to override the default of OR. (Alternatively, the default search could be switched using the "Match All Search Terms" check box.) Note that the search tool ranks matches based on the OR separated search terms working left to right. There are two OR separated terms in this search. The first six words are ANDed together, the second term provides the hint that I'm most interested in the fortran pages that include the word "iceberg." The bulk of the first search term is exclusionary. I do not want any page with klondike, cray, yukon, or iceflyer.
Here's another example:
iceberg fortran compiler program example compileThe ARSC search tool returns 461 pages, but the number one hit is a T3E Newsletter from the year 1999. Why did this get the top spot? The page is ranked on the number of times each search term is found in each page, and also using a left to right precedence of the terms. The first link has the word fortran so many times it outranks the pages that have the more important word, "iceberg." The second link is, however, the introduction to iceberg that made the top of the last search.
Let's contrast with Google:
Google ranks pages based on the number of other pages on the internet that link to it, along with some very complex algorithms for content. The Google page rank is sort of democracy in action, and for the wilderness of the entire internet, it works great. But how many people in the world link to pages designed specifically for ARSC users, on ARSC's web site?
If you want the most popular ARSC web page, based on a limited number of "voters," use Google, and force Google to stay in our domain by adding the search term "site:arsc.edu".
If you want the most current search data with a simple but powerful search system, use the ARSC tool, linked at the bottom of every ARSC web page.
I am always looking for input on how to make this search tool, as well as every part of our web site, the best it can be. Please contact me (email@example.com) with suggestions, gripes, or to just say "hello."

Quick-Tip Q & A
A:[[ I know all about redirecting files in Unix. Like, I can do this: [[ [[ % cat f.newinfo >> my.big.file [[ [[ which puts the contents of "f.newinfo" at the end of "my.big.file". [[ What I really want, though, is to put the contents of "f.newinfo" at [[ the TOP, not the bottom, of "my.big.file". I tried this: [[ [[ % cat f.newinfo ^^ my.big.file [[ [[ but it didn't work. How do you prepend files? # # Dale Clark # There are lots of ways to do this using multiple commands (copying, moving, etc.), but the challenge for me was to do this with a single command: % cat bar bar % cat foo foo % ex -sc "0 r bar wq" foo ### Single command prepends bar to foo. % cat foo bar foo The -s just suppresses interaction (silent). The -c specifies an ex command, which in this case is a compound command, with ' ' as a separator. So, we tell ex to open foo, read in bar at position 0, then write-quit. # # Robert Osinski, Hank Happ, Liam Forbes, and Ed Kornkven's first # solution played variations on a theme. Here are Ed's three # solutions, including the dubious number 3: # 1) Simple shell answer: cat f.newinfo my.big.file > temp ; mv temp my.big.file 2) If you're going to be editing my.big.file anyway, it's just a little harder in vi using the vi command ":r f.newinfo". The complication is that this is going to insert f.newinfo AFTER the current line being edited. To do the prepend then, one must insert a new line at the top of the file % vi my.big.file # insert at the beginning of the line (that's a capitol letter "I") I <CR><ESC> # go to that top line 1G # read in the new file :r f.newinfo # delete the inserted line 1Gdd #save and exit :wq 3) I like the creative approach of the questioner. And it's surprisingly close to working so let's fix it up: % cat f.newinfo ^^ my.big.file > temp ; mv temp my.big.file # # Greg Newby # There's no way I know of to do this that doesn't involve rewriting the old file. This is due to the way files are stored on the Unix filesystems I am aware of: as a sequence of bytes, starting at an address on a disk. Since the file starts at the beginning of the address, inserting at the start of the file involves moving all of the rest of the file. It might be that some of the new database-based filesystems will get around this, and simply let you make a link within a file from the new prepended content to the old. But this is not available currently. So, my recommendation is to instead "cat" or "cp" to a new file, and append the old, then rename. It sounds as though you already know how to do this, but here are some sample sequences: % mv my.big.file my.big.file.old % cp f.newinfo my.big.file % cat my.big.file.old >> my.big.file % rm -i my.big.file.old or: % cat f.newinfo my.big.file > temp % mv -i temp my.big.file Q: Almost every program I compile these days requires some pre-processing. The IBM XLF compiler runs the pre-processor if the source file has the suffix ".F". For files with other typical Fortran suffixes, is there any way, other than renaming the file, to get XLF to run the pre-processor?

I am actually going on my First Turkey hunt this weekend, yeah little late in the season but the Bro in Law and I have been shooting a lot at the range lately and have got the Hankering to go out and try our luck. I have to say the advice you all give out here has been a huge help in our prep. I really enjoy the sight.
A little background on why this year. Last year on an Elk hunt, coming up dry we decided to hop in the truck mid-day and explore, rounding a bend and a little above a stock pond we spotted a few hens head towards the tree line. At the lead was the Biggest Tom I may have ever seen, right then I was telling myself I found a new hobby. Ive seen dozens of Turkey in the wild and this big boy made an impression on me. Thanks again all, good luck and good hunting.

Composer Meredith Monk to discuss her work, March 13
Posted March 10, 2003; 03:26 p.m.
singer, director and choreographer Meredith Monk will discuss her work at 4:30 p.m. Thursday, March 13, in 106 Woolworth as part of the Department of Music's Composers Colloquium series.
Monk, the creator of new opera, musical theater works, films and installations, is a pioneer in what is now called "extended vocal technique" and "interdisciplinary performance." She creates works that thrive at the intersection of music and movement, image and object, and light and sound. During a career that spans more than 35 years, she has been acclaimed by audiences and critics as a major creative force in the performing arts.
Monk has received numerous awards, including the prestigious MacArthur "Genius" Award in 1995, two Guggenheim Fellowships, a Brandeis Creative Arts Award, three "Obies" (including an award for sustained achievement), two Villager Awards, a "Bessie" for Sustained Creative Achievement, the 1986 National Music Theatre Award, 16 ASCAP Awards for Musical Composition and the 1992 Dance Magazine Award.
In 1968, Monk founded The House, a company dedicated to an interdisciplinary approach to performance. In 1978, she formed Meredith Monk and Vocal Ensemble to expand her musical textures and forms. She has made more than a dozen recordings, most of which are on the ECM New Series label. Her current projects include a series of pieces with electronic composer David Berhman and Monk's first orchestral piece commissioned by Michael Tilson Thomas for the New World Symphony.

Quarterback play likely key in Rose Bowl
LOS ANGELES - Both Wisconsin and Stanford have great defensive units, so the team that comes out on top might have to find an advantage on the offensive side of the ball, likely at quarterback.
Stanford starting quarterback Kevin Hogan, a freshman, moved into the starting spot in the team's final four games. Hogan led Stanford to wins in all four of those games, all of which were against ranked opponents.
"I'm feeling more comfortable. I've been learning more, watching more film, and just trying to develop my game a little bit more. So I feel like I've continued to get better each and every week," Hogan said.
"His athletic ability is something you can't teach. When he gets out in space and makes a guy miss or breaks a tackle, that's such a plus. It's something defenses have to account for," Stanford Head Coach David Shaw said.
Like Hogan, Wisconsin's Curt Phillips moved into the starting role for his team's final four games. Whereas Hogan's move was done based on performance, however, Phillips came in because of Joel Stave breaking his collarbone in the Michigan State game.
Stave is now medically cleared to play, meaning we could see two different Badgers playing quarterback in tomorrow's game.17962272
"I'm really happy about it, Stave said. "I put in a lot of time making sure it healed correctly and tried to do what I was supposed to to put myself in this position, so I'm really happy it all kind of paid off."
"I think if you have guys that can bring stuff to the table, it's an advantage for the team," Phillips said. "I don't make any decisions about when the timing of stuff is. But if it's something that can help us and give us a better chance to win, then I'm all for it."
Curt Phillips could be granted an extra year of eligibility, meaning there would be an abundance of capable quarterbacks next season at Wisconsin.

PolyFusion antimicrobial marketed as SafeTouchComments Email Print
PolyFusion LLC has received the SafeTouch trade name for its new antimicrobial masterbatch for thermoplastics.
PolyFusion , based in Angola, Ind., spent more than two years developing the antimicrobial and says it is effective for the lifetime of the relevant plastic product.
SafeTouch has a fast mode of action compared with ion exchange and phenol-based antimicrobials.
PolyFusion says it is marketing the non-leaching, non-mutating antimicrobial where control of the environmental bio-burden is key. It is EPA registered and available in pellets and powders. The masterbatch is compatible with commodity and engineering resins and the company claims it is thermally stable under processing conditions.
The product kills microbes by destroying cell walls.
PolyFusion received the trade name a few months after a manufacturer's representative began marketing it under a more generic name.

University Libraries will create and edit cataloging according to the Anglo-American Cataloguing Rules, 2nd ed., 2002 revision and updates (AACR2); the Library of Congress Rule Interpretations (LCRI); the Library of Congress Subject Headings (LCSH); the Library of Congress classification schedules; and OCLC Bibliographic Formats and Standards.
Pre-AACR2 cataloging copy is to be upgraded to AACR2 standards; any exceptions must be approved by the supervisor. See the section below on upgrading pre-AACR2 records.
RDA records will be accepted and will not be retroactively edited to AACR2, with the exceptions noted below. Also, we will not edit AACR2 records to RDA standards. NOTE: Original cataloging will be created according to AACR2 standards until October 1, 2013, at which time RDA will be implemented according to the RDA Toolkit and the Library of Congress Policy Statements, with the local exception of the GMD as defined below.
As our local catalog is available online, our work represents the department, the Libraries, and the University to users locally and throughout the world. Accuracy and attention to detail are paramount. Please proof your work carefully before you add records to the catalog.
Fixed fields: Check each code. Be sure date type and date(s) are consistent with the date(s) in the 260 field. Refer to OCLC Bibliographic Formats and Standards and OCLC MARC Code Lists for values to be entered in specific fields. (NOTE: The MARC Code Lists link leads to separate links for individual code lists.) Leader and fixed fields are always to be coded at national (full) level, even though level K technically allows for some omissions.
These Descriptive Cataloging codes are valid in the OCLC Desc fixed field:
This fixed field was originally developed to control punctuation on catalog cards. For this reason, it is not officially a "rules used in cataloging" field. There is no separate code for records cataloged according to RDA; code "i" is used instead.
Variable fields: Verify that each of the following fields matches the piece in hand. Make any needed changes before exporting the record to the local catalog. Click on MARC tag numbers in the list below for additional information on each field.
Library of Congress control number (LCCN)
LC Control number and/or canceled or invalid LC control numbers.
Terminal Display
Delete. Used by LC for control elements not accommodated in the fixed field.
National Bibliography Number
Delete. Number assigned to the catalog entry in a non-U.S. national bibliography.
National Bibliographic Agency Control Number
Delete. Numbers assigned by national bibliographic agency other than Library of Congress.
OCLC Control Number Cross-Reference
Retain on serial records; delete on all others. Superceded OCLC numbers for records merged with the current record.
International Standard Book Number (ISBN)
If a book has ISBN's for different bindings, delete those that do not match the book in hand -- IF it is clear which ISBNs apply. Exception: Juvenile literature (see DeGrummond Collection guidelines -- HYPERLINK THIS).
Conflicting ISBN's. When conflicting ISBN's are on different parts of the book and there is no way to tell which is correct, leave them in the bib record, including qualifiers that state the source of the numbers, e.g.:
020 __ 1234567890 (t.p. verso)
020 __ 9781234567891 (back cover)
Multivolume Sets. When cataloging a multivolume set and the record contains ISBN's for both the set and individual volumes, leave all ISBNs in the record.
Price Information. Delete any price information in 020 $c.
Paperbacks. When cataloging a paperback and the ISBN in the record is correct but does not have the qualifier (pbk.) after the ISBN, add the (pbk.) qualifier.
International Standard Serial Number (ISSN)
in a serial record. If there are multiple ISSN's (e.g., additional ISSN's in $x or $y), leave them in.
Cataloging Source
Update holdings in OCLC before exporting, so that $d MUS (or $d MLA) is added to the field. This is the MARC code of the name of the organization(s) that created the original record, assigned MARC content, or modified an existing MARC record.
Local Holdings
The holding library code for items held by University Liibraries. In the past, we had many location-specific OCLC holding codes, which can be seen in our older catalog records. We now use only two: MUSH for titles cataloged for the Hattiesburg campus, and MLAC for those cataloged for USM Gulf Coast. Government document MARC records purchased from Marcive, Inc. may be seen in the catalog with an 049 code of MDOC, which is not an OCLC code. See Holdings Symbols.
LC Call Number (050) Local LC-Type Call Number (090) Local Free-Text Call Number (099)
Our local catalog does not recognize 090 call numbers in the indexing program. 090 is an OCLC internal field, not an official MARC tag. If you find an 090 call number in an OCLC record you are using, change the tag to 050 with 1st indicator blank (no information provided) or 1 (item is not in LC) and 2nd indicator 4. If 090 remains in the record when it is exported from OCLC, the call numbers will not index in our catalog.
If you make any change to an 050 call number with 2nd indicator zero other than adding the date, change the 2nd indicator to 4 to indicate a local call number.
The date in the call number must match the date in the 260 field. Be certain all changes have been made to the call number before exporting.
Do not use 055 (National Library of Canada) call numbers, since these represent Canadian modifications to the LC schedules.
Remove "x" from the end of call numbers for records added to our catalog for new materials. If you are adding a copy to an existing catalog record with an x in the call number, use the x in the call number for the added copy. If you notice that the call number is not consistent in various locations of a title (x's in some locations but not others), pull the books, delete the x, and create new labels. Due to differences between Millennium and our previous system, such inconsistencies will not be easy to spot and may be apparent only from the string of migrated data in individual item records; therefore, these changes are not a high priority.
If you are cataloging a book with an alphanumeric call number (for example, for the ERC or Curriculum Lab) and the cataloging copy has an LC call number, leave the LC number and add the local curriculum classification number in 099. Otherwise, delete all call number fields except the one we are using for our title.
Delete all unused classifications such as 055, 060, 070, 072, 082, 092, 096, etc.
If you are editing a Millennium record with an LC call number in 090 or 099, create a new 050 field with field group tag "Call no." and copy/paste or rekey the call number into the new field. Millennium will not allow Call no. fields to be changed and retain the correct field group tag. After saving the new call number field, delete the 090 or 099.
Title Should match title page (or other chief source of information).
When cataloging CIP copy or copy from non-LC sources, be very careful about 245 title information; it may have changed between CIP and actual publication.
Bracket [ ] any information in the 245 that does not come from the chief source of information (for example, an author statement taken from the verso of a title page).
Videos: Use the container title. If the title in 245 is from the title frame with a 246 for container title, flip these fields and add a 500 note to explain that the title was taken from somewhere other than the title frame. This is a local practice to assist library users.
Foreign films: Title in 245 should be the title in the original language, with English title (if available) given as a parallel title in 245 $b following = and also as a 246 variant title. Example:
GMD Records cataloged according to RDA will not have a GMD in the 245 field, even for nonprint formats. RDA does away with the GMD and replaces it with three new physical description (3xx) fields, described below.
Local practice: As a service to our patrons, University Libraries will continue to use the GMD in our catalog for formats that have historically called for a GMD: microforms, online resources, computer files, visual materials, and realia. If you are working with an RDA record, add the GMD according to the list here.
Print resources such as books, journals, maps, and music scores do not receive a GMD.
Exception/Local practice: University Libraries uses GMD [manuscript] for manuscript collections, which may contain print materials.
Variant Title Add 246 fields for spelled-out forms of numerals and symbols that appear in the 245 field. Also add a 246 for any variations from the 245 title that appear on or in the work. See Bibliographic Formats and Standards for a list of 246 indicators and their meanings.
Edition statement The edition statement on the cataloging record must match the book. For example, do not use and alter a record for the 3rd edition to catalog the 4th edition.
The only exception to this is presence of a "First edition" statement vs. no edition statement at all. If your book has a "First edition" statement and you find a record that matches in every way except that it has no edition statement, add the edition statement and use the record.
A statement such as "Reprinted with corrections, 2013 " is actually an edition statement and belongs in the 250 field (see 260, below). In some foreign languages, the term "edition" is used interchangeably with "printing"; if you are in doubt as to whether the work in hand is actually a different edition, consult a librarian.
If an edition statement has a statement of responsibility recorded in 250 $b, check it against the work you are cataloging.
Imprint (AACR2: Publication, Distribution...) If editing CIP copy or copy from non-LC sources, be sure the publication date ($c) matches the book; anticipated dates of publication may vary from the actual ones.
If the publisher on a record does not match the publisher in the book, do not use that record (this refers to different publishing firms, not to minor variations in the form of a single publisher's name).
Do not treat printing dates as publication dates, with the exception of de Grummond materials. See de Grummond cataloging materials procedure for more information -- HYPERLINK THIS. However, be aware that a statement that indicates revision of content, such as "Reprinted with corrections, 2013," means the book is a different edition and not just a printing. In such a case, we will need a separate record for the revised printing.
See 264 field information below.
Anticipated Date of Publication
Leave this information in if cataloging electronic serials. Delete in all other instances.
Imprint (RDA: Production, Publication, Distribution...) The repeatable 264 field was introduced as part of RDA implementation, taking the place of 260 for libraries that choose to use it. University Libraries will use the 264 field(s) in our cataloging, but if you are working with an existing record with a 260 field, do not change it to 264.
See 260 field information above.
Physical Description
If editing CIP copy or copy from non-LC sources, be sure to fill in all 300 field values.
For multi-volume works, 300 $a is intended to represent the number of volumes in the published work, not how many volumes a library owns. For example, if the bibliographic record reads 3 v. and we own only vols. 1-2, do not change 300 $a to read "2 v." If 300 $a is open (i.e., just "v."), do not fill it in unless you know the work is complete.
Do not make multiple 300 fields to show accompanying material; instead, record it in 300 $e after a plus sign. If our copy lacks the accompanying material, record that fact in a 590 note, e.g.
590 __ Cook Library copy lacks computer disk.
Use the term "disk" for a computer file on floppy disk. Use "disc" for a computer file on an optical laser disc (CD-ROM) with text or music.
See procedures on Books with Accompanying Electronic Resources for additional information.
As noted above, RDA replaces the GMD with three additional 3xx fields:
While we are cataloging according to AACR2, we will not add these fields to records. However, if you are working with an RDA record, do not delete the fields, even if you are adding a GMD to the 245 field. See 336-338 below for more information and live links to OCLC Bib Formats.
Content Type (RDA)
The form of communication through which a work is expressed. Used in conjunction with Leader /06 (Type of record), which indicates the general type of content of the resource. Field 336 information enables expression of more specific content types and content types from various lists.
Multiple content types from the same source vocabulary or code list may be recorded in the same field in separate occurrences of subfield $a (Content type term) and subfield $b (Content type code). Terms from different source vocabularies are recorded in separate occurrences of the field.
See training materials.
Media Type (RDA)
Media type reflects the general type of intermediation device required to view, play, run, etc., the content of a resource. Used as an alternative to or in addition to the coded expression of Media type in field 007/00 (Category of material). Field 337 information enables indication of more specific media types and media types from various lists.
Multiple media types from the same source vocabulary or code list may be recorded in the same field in separate occurrences of subfield $a (Media type term) and subfield $b (Media type code). Terms from different source vocabularies are recorded in separate occurrences of the field.
See training materials.
Carrier Type (RDA)
Carrier type reflects the format of the storage medium and housing of a carrier in combination with the media type (which indicates the intermediation device required to view, play, run, etc., the content of a resource). Used as an alternative to or in addition to the coded expression of carrier type in field 007/01 (Specific material designation). Field 338 information enables indication of more specific carrier types and carrier types from various lists.
Multiple media types from the same source vocabulary or code list may be recorded in the same field in separate occurrences of subfield $a (Carrier type term) and subfield $b (Carrier type code). Terms from different source vocabularies are recorded in separate occurrences of the field.
It has historically been our policy to trace most series. Millennium indexes series titles in 440 (obsolete) or 830 fields in the general title index. Despite LC's discontinuing series authority work several years ago, University Libraries will continue to trace series (i.e., give them an access point that appears in the title browse index of our catalog).
Series in 490 with 1st Indicator Zero (490 0_)
Older Records with Series in 440
Remove initial articles from the 440 and change 2nd indicator to zero. Otherwise, accept the series statement as it is. 440 series will be automatically converted to 490/830 by Marcive when the bibliographic records are sent to them for authority work.
Series in 490 1_/830 Field Combinations
Accept fields as they are. The series will be reviewed when the records are sent to Marcive.
General NoteIf an item has an index but no bibliography, a note about the index should be included.
500 __ Includes index.
BibliographyReformat older bibliographic notes (e.g., "Includes bibliographies," or "Bibliography: P. 45") to current usage, which is "Includes bibliographical references (p. 45). Bibliography and index notes should be combined in this form:
504 __ Includes bibliographical references (p. 45) and index.
Do not ADD formatting (subfield coding) to contents notes. However, if a record you are working with already contains a formatted contents note (505 00), leave the formatting in.
Periods are no longer used at the end of the contents of each volume, but the note itself does end with a period.
505 0_ Vol. 1. Civil War years -- v. 2. Reconstruction period.
See footnote 10 in AACR2 abbreviations table (App. B.) for use of abbreviations "vol.," and "v." in notes.
Past practice at University Libraries was to add contents notes to edited works in the areas of science/technology and literature when contents notes were lacking as an aid to patron access and findability. Edited works and collections outside science/technology and literature received added contents notes if there were fewer than 15 titles. This practice may be reevaluated in the future. [lkg 02/15/2013]
Local NoteUse only for notes that describe University Libraries' copy, not all copies of the work, e.g.
590 __ Cook Library item 32280010783280 imperfect; lacks p. 121-125. 590 __ Mississippiana item 32280010783017 inscribed by the author.
Note the use of the barcode as a unique item identifier, since University Libraries no longer uses copy numbers in call numbers.
See De Grummond cataloging procedures for instructions on notes related to numbered printings. HYPERLINK THIS
Genre Headings
Use the LC thesaurus for genre headings in the 655 field. Change the form:
FROM: 655 _7 Historical fiction. $2 lcsh
TO: 655 _0 Historical fiction.
Make this change only for those 655 fields that are followed by $2 lcsh. If there is any other thesaurus code in 655 $2, do not change it.
Added entriesAdded entries must be "justified" -- i.e., if a heading is used as an added entry, there must be a reference to it in the body of the record, either 245 $c statement of responsibility or in a 5xx note. Under AACR2, LC dropped the use of $e (editor, illustrator, etc.) for most 700 fields. However, RDA has a renewed emphasis on recording the function of creators or contributors, so we will see more use of $e.
For Special Collections materials, there may be requirements to add more information. Refer to the instructions for those specific collections.
Do not use 740 for multiple titles within a single work, unless there is no author -- use 700 $t (author/title entry). If 740 has been used for a variant of title proper (cover title, etc.) or portion of the title, move the variant to 246 with the proper indicators.
Use 790 (personal name) or 791 (corporate body) field for local interest added entries (e.g., an entry for a person or corporate body not directly responsible for a work, such as a thesis advisor). 791 is also used to provide keyword access for named collections within the Libraries.
791 2_ Floyd C. and Stella T. Dickman Collection.
Series Authorized form of series when different from the form that appears on item. See 4xx above for instructions on series statements.
Vendor information
Initial articles: Do not use initial articles in 246, 440, 505, 600 $t, 700 $t, 740, 830. The system does not have any provision for skipping articles in indexing some of these fields, and articles are omitted for consistency's sake in others.
Upgrading Pre-AACR2 copy: (lock and replace for credit)
Fixed field: Change Desc to code a. Some older records may lack correct coding for bibliographic information, indexes, illustrations, and /or country of publication. Check the entire fixed field.
Fixed field: Change Desc to code a. Some older records may lack correct coding for bibliographic information, indexes, illustrations, and /or country of publication. Check the entire fixed field.
Add ISBD punctuation and spacing. If there is not an author statement, supply one. If existing author statement includes [by] and "by" does not appear on the title page, remove it.
Add ISBD punctuation and spacing. Pre-AACR2 cataloging called for bracketing dates if they appeared anywhere but the chief source of information, which was usually the title page. If the work you are cataloging has the date on the title page verso, remove the brackets around the date in the cataloging record.
Add ISBD punctuation and spacing. Collations in pre-AACR2 cataloging could be very detailed, with multiple page sequences and types of illustrations. The rules have since been simplified to allow for description of complex paging as "1 v. (various pagings)" and to describe most types of illustrations as "ill." When editing older cataloging, ask yourself if the 300 field would make sense to a patron; if not, simplify it.
If you change an illustration statement in the 300 field, fixed field codes in the "Ill." area should be changed to match. Similarly, book sizes used to be recorded to the half centimeter; sizes are now rounded off to the next highest whole centimeter.
NOTE: These instructions are for upgrading old, pre-AACR2 records to AACR2. The purpose of this upgrading is to include information that was often omitted under older cataloging code, such as author statements and index notes. As noted above, we will not change AACR2 records to RDA.
NOTE: These instructions are for upgrading old, pre-AACR2 records to AACR2. The purpose of this upgrading is to include information that was often omitted under older cataloging code, such as author statements and index notes. As noted above, we will not change AACR2 records to RDA.
General Reminders:
Use the "Derive new record" command when creating a new record that borrows information from another similar record. When creating "new" records derived from LC copy, do not leave the (Fixed Field) Source blank; replace the blank with code d. Review your record carefully to be sure you have removed all information that does not apply to the title we own.
For a financial credit, lock and replace K level records that already have a call number and at least one subject heading. For example, add ISBD punctuation or otherwise upgrade to AACR2. For K or I level records with no LC call number and/or no subject headings, see the Head of the Cataloging Unit before upgrading. Do not change the encoding level from K to I without clearance from the department head.
Errors in OCLC records created by University Libraries (MUS $c MUS) must be corrected. If you find an error in an original record after it has been added to the OCLC database, lock and replace the record. If this is not possible because another library has already used the record, we must file an error report with OCLC. See the Head of the Cataloging Unit if you have questions on this procedure.
NOTE: This document is a work in progress and will be revised as needed to reflect changes in national and local standards. When you are unsure of what to do, always ask for assistance from a supervisor.

|>> Archive: Warmwater Gamefish Flies Freshwater Bass, pike, muskie?!?
|Topic Review (Newest First)
|Dble Haul
|That's a clever combination of foam and deer hair....it also looks substantial enough that a pike might take interest. Very creative!
Nice fly. Definitely a winner in my book. I just love the "action shot" of the fly in the water too.
Freshwater bass will constitute most of my summer fishing (but not the fall!) and I may tie up a few of these flies. I have a stellar largemouth pond near where I work in NH and this would be just the ticket for coaxing biguns out of the partially submerged bushes that ring the shoreline. I have had many a sleigh ride while fishing from my float tube in this pond.
Nice job!
That makes me feel like hitting the lilly pads again. I've had some tremendous fun working bugs for bigmouths and it's been a long time. I stopped by a pond near the office at lunch recently and found some really nice largemouth bass cruising the beach shallows on the sand, kinda like a mini-monomoy. It would be a kick to chase these guys on the bugrod some morning before work. This would be a great fly to do it with!
Foam & Deer Hair Frog Slider
I wanted to tie a big, floating weedless fly to fish the slop for largemouths. A deer hair bug would be the obvious choice, but I can't seem to spin deer hair tight enough to make it as bouyant as I want. I decided to try a foam popper body, mounted backwards, with deer hair behind it to bulk it up a little. Here's what I came up with:
Hook: 3/0 bass bug hook
Thread: heavy white monocord
Tail (legs): olive hackles (I'll tie on rubber legs when these break off)
Body: deer hair, olive over white
Weed Guard: white super hair, tied near hook eye and angled back toward hook point.
Head: white styrofoam popper (Orvis #2), reversed, with top half colored olive
Eyes: stick-on (or paint/marker)
I tied all the materials onto the hook and then superglued the popper in place. I had to widen and deepen the slot to make it fit properly. The weedguard fits inside the slot. After the glue dried, I trimmed the deer hair a little (I may trim it some more), colored the top half of the popper, stuck on the eyes and gave the popper a coat of Softex. I also put softex on the weedguard to make it stiffer but still flexible.
It casts easily on the 9wt, floats well and makes a nice "sploosh" and wake on the retrieve. It hasn't fooled any fish yet but I only gave it a brief test.

He's not a number one, I'll let the market prove me wrong on that one. If he gets paid more than 12 million a year on his next contract I'll eat crow.

Senate Panel: Homeland Security Data Centers Mainly Terrorize Citizens
Jason Mick
October 3, 2012 7:33 PM
Recipient E-mail
Sender E-mail
Report finds that while the centers may lead to civil liberties violations, they don't do much to catch terrorists
In a new 146-page report
by the
Senate Permanent Subcommittee on Investigation
, a bipartisan panel of senators calls into question the
U.S. Department of Homeland Security
's (DHS) claims that so-called "Fusion" data centers have successfully been employed to stop terrorists.
I. Surprise! The Fed. Government Wasted Taxpayer Money on Abusive Scheme
While the DHS claimed that the centers were used to stop the Afghan immigrant Najibullah Zazi's 2009 plot to bomb the New York subway, the Senate "could identify nothing that uncovered a terrorist threat, nor could it identify a contribution any fusion center made to disrupt an active terrorist plot."
Contrast that with what DHS Secretary Janet Napolitano said in a 2010 speech in which she commented, "It was a fusion center near Denver that played the key role in 'fusing' the information that came from the public with evidence that came in following the [subway plot] suspect's arrest by the FBI."
The Senate committee said that the 2009 plot and others -- like a 2010 effort to place a car bomb in Times Square -- were not cracked by the Fusion centers at all. The officers involved in the cases would have done the exact same thing they did to crack those cases, with or without the data center. For example, in the subway plot, the Colorado state troopers who solved the cases were working
their state's data center, but their detective work to discover and stop the plot came from the agency they were primarily reporting to -- the
U.S. Federal Bureau of Investigation
The Senate concludes that when all the privileged details of the investigations were considered, there was no sign that the pricey data centers were successful at fighting any known terrorist plot.
So what
the data centers accomplish? According to the panel the legacy is mostly negative. They claim the Fusion centers -- whose objective is ostensibly to share national intelligence with state/local law enforcement and analyze potential terrorist threats -- in the end mostly ended up violating U.S. citizens' civil liberties.
"Fusion" data centers did little to stop terrorism, but did violate civil liberties and waste taxpayer dollars, according to the Senate. [Image Source: The LA Times]
Writes the panel, "[DHS liaisons] forwarded 'intelligence' of uneven quality — oftentimes shoddy, rarely timely, sometimes endangering citizens' civil liberties and Privacy Act protections, occasionally taken from already-published public sources, and more often than not unrelated to terrorism."
One example of such a shoddy effort is in the case of the Illinois Statewide Terrorism and Intelligence Center's recent claims that a Russian hacker had stolen sensitive usernames and passwords from a state utility. Those claims would haunt an IT worker from the utility, who had merely been doing his employer's bidding by remotely (and securely) managing systems while abroad on vacation.
Because of the poor detective work, it took some time for authorities to realize the devious "hacker" was merely a figment of agents' overactive imaginations. And in the meantime the employee faced unwelcome scrutiny, for basically doing his job.
II. Trading Freedom for Security
It's a story that Americans have grown
all too accustomed to
in the post-9/11 "police state" era: unwilling to be troubled with solid detective work, and with a wealth of
new abusable privileges
, citizens' civil liberties are trampled even as the government does little to ensure their safety.
Worst of all, the Senators were unable to even able to figure out how much was spent on the data centers, only able to ascertain it was between $289M to $1.4B USD in taxpayer money arguably down the drain.
Of course the bipartisan panel can only wave the finger at
Presidents George W. Bush
Barack Obama
who signed the funding bills and Fusion center plans into law. After, all it was the House and Senate who passed the funding and authorizations that called for the centers in the first place.
Some defend the Fusion centers. For example the
Los Angeles Police Department
's (LAPD) counterterrorism chief, Deputy Chief Michael Downing,
Los Angeles Times
that despite a lot of "white noise", "There are occasionally gold nuggets."
Unsurprisingly DHS spokesman Michael Chandler also labeled the investigation as "fundamentally flawed", commenting, "The committee report on federal support for fusion centers is out of date, inaccurate and misleading.
The DHS claims the Senate is wrong and that the "Fusion" centers are great. [Image Source: CyTalk]
Whether or not the centers were as useless as the Senators' report claims, the report does make clear the key problem was that the centers were tasking state/local law enforcement agents with investigation responsibilities that they were incapable of handling, rather than leaving their use up to the various sophisticated federal law enforcement agencies that know how to best make use of those mid-level skilled resources. The results ranged from mistakes to potential abuse.
Thus the U.S. is left to grapple once again with the question of whether its politicians are playing a game of Security Theater.
For those interested, the Senate Permanent Subcommittee on Investigation members include:
Sen. Carl Levin
Sen. Thomas R. Carper
Sen. Claire McCaskill
Sen. Mary L. Landrieu
Sen. Jon Tester
Sen. Mark Begich
Sen. Tom Coburn
Sen. Susan M. Collins
Sen. Scott Brown
Sen. John McCain
Sen. Rand Paul

Family: Scombridae, Mackerels view all from this family
Description The Atlantic Spanish mackerel, Scomberomorus maculatus, is a migratory species of mackerel that swims to the northern Gulf of Mexico in spring, returns to south Florida in the eastern gulf, and to Mexico in the western gulf in the fall.
The fish exhibits a green back; its sides are silvery marked with about three rows of round to elliptical yellow spots. Lateral line gradually curving down from the upper end of the gill cover toward caudal peduncle. The first (spiny) dorsal fin is black at the front. Posterior membranes are white with a black edge.

So for example if line 0 was compatible with lines 1 and 2, line 1 was compatible with 0 and 3, line 2 was compatible with 0, and line 3 was compatible with line 1, then the number of ways I can build a wall of height "3" would be:
For a total of 10 ways. Make sense?
I already have written a function that calculates the correct result when given a wall height (between 1 and 10) and a set of BlockLine objects that already have their compatible_line data entered. The function works great for small to mid-size wall configurations (a wall of height 10 with 65 possible lines is computed in a fraction of a second). But when I change the number of lines to a larger number (3329 in the test that I'm using) the function is exceptionally slow for larger heights. (3329, 5) is still computed in under a second, but (3329, 10) takes much much too long (several minutes). So I'm trying to figure out how to optimize this code so that it performs well for the larger input sets. Here's the source:
/** \brief Determines the number of possible configurations that can build a block wall of a specific height *** \param wall_height The height of the wall, as a number of wall lines *** \param lines A reference to the container where all possible block line permutations are stored *** \return The number of wall configurations *** \note The BlockLine objects stored in the lines argument must have all their line compatibilities *** set before this function is called. *** *** This function works by starting with constructing the base of the wall with all possible lines. For each *** line at the base, the compatible lines are placed on top, and those lines have their compatible lines placed *** on top of them and so on until the wall has reached its maximum height. **/ int64_t ComputeNumberWallConfigurations(int wall_height, vector<BlockLine>& lines) { // In the case that the height of the wall is one, the number of configurations is simply the number of line permutations if (wall_height == 1) { return lines.size(); } // A counter that keeps track of the number of wall configurations int64_t num_configurations = 0; // A stack of all the lines that build the current configuration being examined vector<int> line_stack; // A companion stack that tracks the index of the next compatible line to examine for each line in the stack vector<int> next_stack; for (int i = 0; i < lines.size(); i++) { // Lines that are not compatible with any other line can not be used to form a wall that is two or more lines tall if (lines[i].compatible_lines.empty() == true) { continue; } line_stack.push_back(i); next_stack.push_back(0); int64_t temp = 0; printf("Constructing wall with base line: %d ... ", i); // With the base line established, now determine all possible configurations for the wall for the provided base line while (line_stack.empty() == false) { int this_line = line_stack.back(); // (Case 1): If the next line pushed on the stack would be the top of the wall, add the number of compatible lines for this line and pop if (line_stack.size() == (wall_height - 1)) { temp += lines[this_line].compatible_lines.size(); num_configurations += lines[this_line].compatible_lines.size(); line_stack.pop_back(); next_stack.pop_back(); } // (Case 2): There are no more compatible lines to examine for this configuration on this level. Pop back to a lower level. else if (next_stack.back() >= lines[this_line].compatible_lines.size()) { line_stack.pop_back(); next_stack.pop_back(); } // (Case 3): Add another line to the top of the stack and increment the current line's "next" index else { int next_line = next_stack.back(); next_stack.back() += 1; line_stack.push_back(lines[this_line].compatible_lines[next_line]); next_stack.push_back(0); } } printf("number configurations == %lld\n", static_cast<long long int>(temp)); } return num_configurations; }
Its a pretty simple algorithm as you can see. It used to be a recursive function, but I rewrote it to be an iterative version when I noticed how slow it ran. Basically I build the wall up from the bottom one line at a time until I'm at the second to last line from the top. Then I simply add to my accumulator variable (num_configurations) the amount of lines I can put at the top, then pop back down the stack.
I realize that this algorithm is a prime candidate for multithreading and that could improve performance (launch each while(line_stack.empty()) loop logic in its own thread) but I don't really want to make this code multithreaded if I don't have to. Plus, I'm kind of doubtful that it would give me the degree of performance that I'm seeking unless I'm launching these threads across 64 different processor cores or something. I've been staring at this function for an hour and I haven't though of any way to drastically increase the performance. Is there something that I'm missing?
One behavior that I did notice during my testing with these larger input sets is that the further along I get, the slower it seems to take for each base line. What I mean is, when this function starts running the first few hundred lines are printed out very quickly
(each line computed quickly, hundredths of a second)
Constructing wall with base line: 0 ... number configurations == 1
Constructing wall with base line: 1 ... number configurations == 252
Constructing wall with base line: 2 ... number configurations == 731808
Constructing wall with base line: 3 ... number configurations == 267227532
Constructing wall with base line: 4 ... number configurations == 13534077843
(each line computed slowly, several seconds each)
Constructing wall with base line: 468 ... number configurations == 1733285040
Constructing wall with base line: 469 ... number configurations == 2477179776
Constructing wall with base line: 470 ... number configurations == 2673027300
Constructing wall with base line: 471 ... number configurations == 2108819760
Constructing wall with base line: 472 ... number configurations == 808799196
Constructing wall with base line: 473 ... number configurations == 6573600
I examined my performance monitor and I didn't see anything wrong with the memory usage. The process remains static at 800KB of memory and 100% CPU, so I'm pretty certain that this is a computationally bound performance issue and has nothing to do with inefficient memory access.

K-1 MAX Madrid Show This Weekend
- Written by Dave Walsh
Here's a show announcement that kind of snuck up out of nowhere - this weekend in Madrid, Spain will be a regional K-1 MAX show. The show is being put on by K-1 MAX Madrid, and will feature a traditional 8 man tournament. These kind of regional events are not out of the ordinary for K-1, who brand many smaller, local shows as K-1 shows. While these shows are affiliated with K-1, they are typically not a part of the official K-1 season - meaning don't expect mention of this event on the K-1 website, or for the tournament winner to automatically enter the GP Final 16.
The biggest name in the tournament is definitely Warren Stevelmans. A K-1 MAX veteran who won the MAX 2008 Netherlands tournament, Stevelmans has been in there with the division's very best, including Andy Souwer, Giorgio Petrosyan, and Albert Kraus among many others. He fights often, and almost always against tough competition, so his record only stands at 4-5 in the last 2 years, but those loses all come against tough opposition. I would consider him the favorite in this field.
Stevelmans's toughest challenger here is likely Rachid Belaini, who comes in off a huge win over the top 25 ranked Khem Sitsonpeenong at It's Showtime in September. If Belaini can keep that momentum going, he can definitely win this event and use that victory as the start of a big 2011.
Also in the tournament are WBC champion Alex Asumu; Hassan Ait Bassou, a good fighter making the move up to 70kg from his normal 63kg weight; Jonay Risco; Manzy Pauwels, a Muay Thai fighter who won a similar regional tournament in 2009; Rafa Del Toro; and Rafi Zohueir, a Muay Thai fighter who was slated to represent Spain on the ill-fated The Contender Asia Season 2.

The cascade of civil upheaval that began in 2011 continues to alter the Arab world's political landscape and has added new layers of uncertainty to stalemated Israeli-Palestinian peace process, with Palestinians bidding for full membership at the United Nations in 2011. Additionally, the ongoing conflict in Syria and concerns about Iran's nuclear program have siphoned global and regional attention from efforts to restart peace talks.
Despite general Israeli and Palestinian public support for a two-state solution (ForeignPolicy), some analysts suggest a peace settlement may be more remote than at any point since the Oslo Accords established a new framework for negotiations in 1993. Republican presidential candidate Mitt Romney visited Israel in July 2012 to underscore his vigorous backing of the country he sees as the United States' closest ally in the region, while chiding the Obama administration for what he sees as flagging support. Obama's relationship to Israel also garnered renewed attention during the Democratic National Convention in September after Democrats omitted and then restored language affirming Jerusalem as the capital of Israel in their platform.
Obama often reiterates his firm commitment to Israel's security while supporting a two-state solution with borders based on 1967 lines. But his failure to visit Israel during his presidency and tensions with Israeli leader Benjamin Netanyahu over Israel's continued settlement expansion and other issues have caused friction in the U.S.-Israel relationship.

Destroying the Dam
Restoring the Elwha
Student Exploration
How will the removal of the Elwha dam affect the freshwater ecosystem upstream?
For over a hundred years in the Pacific Northwest, the Elwha freshwater ecosystem was being disturbed by the Elwha dam. Salmon that typically spawn upstream were not able to do so. Check it out: Restoring the Elwha
How were the salmon being affected by the dam? By simply removing the dam, will the ecosystem improve? What will change?
Extension Investigation
- Hydoelectric power, a renewable energy source with no pollution, is an excellent alternative to fossil fuels. Removing the dam means removing a good source of power. How was the dam threatening the survival of salmon? Pacific Salmonids: Major Threats and Impacts Are there other threats to the survival of the salmon in the Pacific Northwest?
- As mentioned in the video clip, scientists are paying close attention to the number of salmon present in the Upper Elwha River to assess how the ecosystem is improving. How are they measuring the population growth? If the salmon population increases in the ecosystem, how will that impact other organisms? Create a "before" food web and an "after" food web showing the other players that would be affected.
- How will the shape of the river change as the dam is removed? How will incorporating log jams improve areas for salmon to spawn? Build a model or use a stream table to simulate the Elwha river with the dam and without the dam. Add log jams. Observe the velocity of stream flow and locations of sediment deposition.

Well, Guido's post to python-dev made me take a look at Advogato again, and found that there's now a password-recovery feature. So I'm back!
It's been a long time since I've posted here, and I need to update my "who am I" text as well.
Well, Guido's post to python-dev made me take a look at Advogato again, and found that there's now a password-recovery feature. So I'm back!
It's been a long time since I've posted here, and I need to update my "who am I" text as well.
The book I co-authored has finally arrived! Python & XML, from O'Reilly, is now available; it should start to appear in bookstores over the next week. Hopefully you'll find a copy in time for the holidays! It's not like there's anything else to do, now is there? ;-)
Well! I certainly haven't written anything here in a long time.
I suppose I've been busy, but it's not easy to know just what I've done. I've learned a bit more about Zope and spent time working on a variety of documentation issues for Python. I've done a little bit more on the XML conversion project there, but mostly just maintenance so the preliminary conversion doesn't fall too far behind the actual definition of the markup in the LaTeX version. There have been a few new things added, but not too many.
Lately I've been working on a new profiler for Python, and this one shouldn't be so darn slow. Written entirely in C, HotShot never touches Python code and avoids the slow path calling PyCFunction objects; to the best of my knowledge, it's the first profiler that uses the new profiler/tracer API introduced in Python 2.2. I expect to check the code into the Python CVS repository tomorrow. It shouldn't be too hard to create a coverage tool using the same basic model, and that should be really fast -- the slowest thing about the profiler is getting the time using a system call. I guess the next thing to work on once we have a basic analysis tool will be to get timing information faster.
Oh, and I've written a book. Well, part of one anyway; I've never even met my co-author. The book, titled Python & XML, should be out by the end of the year. Watch for it!
Well, well, well... I've been busy lately! I've spent a fair bit of time looking into some of the evolving W3C specifications, especially the XML DOM stuff. It's a little interesting seeing the directions the specs are being pulled in -- not sure of the motivations, sometimes!
My own DOM implementation is growing, but only slowly at this point -- I've worked on my Level 3 Loading module, and have at least a few test cases for non-default behaviors.
I spent a little time this evening working on my scripts for conversion of the LaTeX documentation for Python to XML -- perhaps that's not such a hopeless goal! I think I need to think further about the following topics:
Not much time to write at the moment, so I'll keep this short.
The new Expat bindings definately offer some nice functionality, and there will be more to come once I've found time to fix some bugs in Expat itself. There's no way I'll be able to get to that until after the Python conference in Long Beach. Anyway, the latest bindings are present in the Python 2.1 CVS tree and in PyXML 0.6.4 and newer, but you need to have the new Expat library pre-installed for the newer features to be used.
The weak references implementation for Python has just about been refined to the point where we're happy with it -- I need to implement support for rich comparisons for the proxy objects, but that's all that needs to be done that I'm aware of. The code needs to be exercised more to make sure bugs are shaken out. Martin von Loewis and Neil Schemenauer have both made very valuable contributions to the implementation.
Acquisition is still bugging me, but I can wait for another time to talk about that. I really need to work on my talk for IPC9.
Well, I guess I've been busy, 'cause I've not written anything here for a while. I should develop a better habit of it.
For now, we're done with the second alpha release for Python 2.1, so that'll give us a little time to catch up in other work, like the stuff our employer really wants us to do. I've been working on a project for Zope called Parsed XML. There are a handful of us working on it, but I'm mostly working on the DOM core. This project is moving along quite rapidly, and I'm a little skeptical of saying that we're anywhere near ready for calling a release `stable.' For some reason, I doubt the choice will be mine! Regardless, it has been interesting working with acquisition for the first time -- it feels pretty fragile, though I think I understand why it's considered desirable in the context of Zope.
The continuation of the development of James Clark's Expat XML parser has been slow. Clark Cooper and myself are working on maintaining Expat and developing it to provide more information via the API so that scripting languages can pick up a lot more (Clark maintains the Perl interface to Expat, and I'm extending the Python binding). We're also building the parser as a dynamically-linked library so that client code doesn't run into problems when multiple components link to the library -- this is a problem that has been noticed in the context of Apache modules, and can easily be found elsewhere as well.
The new Python bindings to Expat will offer much more information to the application builder. I'm using the enhanced bindings in the Parsed XML project and hope to merge it into PyXML and Python after resolving a few more issues.
Python 2.1a2 contains my implementation of weak references, using an approach to invalidation which we think works really well with reference counting. My next task for Python will be to convert the build process for the documentation to use a non-recursive Makefile, similar to what Neil did for the build of the interpreter. It wouldn't take long if I'd just sit down and do it!
Well, Guido sent out the announcement about the move to Digital Creations today, so we can all breathe a sigh of relief:
Checkin mail from SourceForge this week hasn't been working at all, and we haven't been able to get ahold of them to see how we can help. It's really hard to develop anything when we don't know what anyone else is actually getting done, and patches aren't getting reviewed. Hopefully this will get fixed soon, but their MTA seems to be botched. That's what happens when you run sendmail with more traffic than it can handle. ;-(
I have managed to get a lot of tedious stuff done in spite of the SourceForge mail problems and wrapping up talks with our new employer. Most of the Python standard library has been run through Tim Peter's reindent.py script, which gets rid of hard tabs, trailing whitespace, blank lines at the end of the files, and, most importantly, converts everything to 4-space indents! Now we just need to write the style guide and include it in the standard Python documentation. The XML package documentation is starting to fall into place, and I've written a lot more of the "LaTeX Primer" for the Documenting Python manual.
The people at iUnivere don't seem to be interested in updating their "on-demand" published Python manuals to recent versions of the documentation, so I'm interested in finding someone who wants to publish short runs or on-demand copies of the most interesting parts of the Python documentation. One of the problems is that few people want to buy printed copies, and the other is that there's a lot of it. Or are people really keen on printing their own?
(If you know of a publisher of open source documentation interested in short-run work, please let me know about them!)
I've started to receive comments from people who want to see the bzip2 version of the documentation kept around, with the suggestion that people are more likely to switch if they knew how much shorter the download was. I've changed the documentation download page so the file sizes are available; we'll see if that makes a difference.
While between employers, I created a new project on SourceForge; it's called "GPath -- A C Library for Path Algebras. A neat idea; we'll have to see if it's really useful, though!
Enough chatter, I need to walk the dog.
The Python 2.0 release candidate is out, and there's more than ever to do in the documentation. I've been culling through my accumulated email and making all the little changes that seem to be needed just after I've packaged the documentation, and expect to have a lot of the really small nits fixed in time for the final release.
I also really need to buckle down and work on the documentation for the XML package; there's a lot of new material there that needs to be written, but Martin & Paul are working on new text for some of the components most in need of documentation. I need to integrate some changes from them and get a new development copy up soon; I'll push one in an hour or so, but that won't have the new XML documentation in it.
The conversion tool to convert the LaTeX sources needs to be updated to the new XML code (xml.dom.minidom); the DOM object constructors have changed, and there may be some changes related to hackery used to do things like change the names of existing elements. --sigh--
Today's big accomplishment: I got my INBOX back below 2500 messages! Don't send me any new ones. ;)
Well, the documentation for Python 2.0 is mostly stable, and shows a lot of improvement over the 1.6 documentation. There are still a few things to do to work around LaTeX2HTML problems, but that seems to always be the case. Every LaTeX2HTML problem pushes me that much closer to getting back to the XML conversion.
I've set things up so that I can easily publish the HTML for what's in my working directory at our FTP server, so it'll be easier for people to review the state of the documentation without having to install all the tools needed to build it from the LaTeX sources.
New HTML Parser: The long-awaited libxml2 based HTML parser code is live. It needs further work but already handles most markup better than the original parser.
