Supervisor's Notes February 2017
We have reached this winter's halfway point but we also know that, while February may be the shortest month, it is usually the snowiest. If and when sufficient snow finally returns, please take advantage of winter recreation activities, including groomed cross-country skiing and snowshoeing trails at the Western Turnpike Golf Course, and sledding at the Winter Recreation Area, just south of Tawasentha Park on Route 146. The Parks and Recreation Department's webpage and office (456-3150) has information about winter activities and has available cross-country skis and snowshoes for rent on weekdays at the Parks' Office on Route 146, opposite Tawasentha Park.
While the winter months can be busy, they allow time for preparing the parks and golf course for the upcoming summer. Parks Department and Golf Course employees are busily trimming trees, painting structures, working on historic properties, and doing other work that is necessary to make Town facilities ready for use. This is also the time for planning the expansion of hiking trails in the growing Town-owned open spaces and adding amenities to the Town parks.
We soon expect to see progress on a number of projects. NYS DOT should complete the scoping and design work for the planned improvement of the Carman Road/Lydius Street intersection. A new sidewalk will also be installed on West Old State Road from Carman Road to Lynnwood Elementary School. As these projects progress, we will share all available information on the Town website and by other means to minimize inconvenience.
Several senior citizen housing developments have been approved or are currently under Board review. These developments will offer a wide-range of housing opportunities from independent to assisted living. Among the goals of the recently enacted Zoning Code was the expansion of affordable housing options for retired residents.
The Town will soon construct water lines on Route 158 and an interconnection with the Town of Rotterdam. This connection will expand available water sources for an ever-increasing high demand during summer months. After testing and confirming the anticipated capacity, this connection will lessen the Town's dependency on other water sources.
I recently had the opportunity to honor First Lieutenant Lanny Ladouceur who, on May 19, 1970, at 23 years of age, lost his life when the helicopter that he was flying was shot down in Vietnam. The ceremony was attended by Lanny's widow, brother, and mother, who is the former president and oldest member of the Albany Chapter of Gold Star Mothers. Members of Gold Star Mothers, Tri-County Vietnam War Veterans, American Legion, Patriot Guard, and Town Police were present to honor Lieutenant Ladouceur and support his family. In honor of Lieutenant Ladouceur, the Town Board dedicated West Lydius Street from Carman Road to Church Road as "First Lieutenant Lanny G. Ladouceur Memorial Highway."
Please remember that law prohibits parking overnight on streets and following too closely to the Highway Department's snow trucks. These rules enable the Highway Department to keep Town roads clear and provide adequate clearance for fire truck and emergency vehicles. Please also help Fire Departments by keeping hydrants clear of snow.
Thank you again for taking the time to read these notes. Upon behalf of fellow Town employees, we hope that you safely enjoy the winter months and look forward to the coming spring.

Backstreet Boys Follow Korn in Boycotting British Petroleum
Backstreet Boys have formed an unlikely alliance with rockers Korn and joined their call to boycott fuel giants British Petroleum to protest the devastating oil slick in the Gulf of Mexico. The spill from the BP rig, which exploded in April, has been declared the worst environmental disaster in U.S. history, prompting Korn to show their disdain by banning their tour bus drivers from filling up at BP gas pumps while on the road this summer.
Frontman Jonathan Davis said, "We need to do our part to let BP know there are consequences for causing something like this. We want to send a message to corporations like BP so that they will take more preventative measures in the future." He further stated, "The more costly their punishment, the more money they will spend to make sure disasters like this don't happen again. It's plain and simple capitalism."
Backstreet Boys recently performed a gig in Biloxi, Mississippi, where they witnessed the extent of the oil spill for themselves, and singer Nick Carter admits he was left heartbroken by the slight of the animals caught up in the mess. He says, "I'm devastated by what I've seen first hand and on the news. I've always been a marine activist and seeing pictures of oil-covered animals breaks my heart."
And his band mate Brian Littrell is calling on their fellow musicians to follow Korn's lead. He adds, "We just played Biloxi last week and I have to tell you people are really worried down there. This boycott is about making a statement, letting people know how we feel and to stand for something."

Sea Shepherd urges strong action on sales of whale meat in Hong Kong
- Details
- Written by arounddb
The influential marine wildlife conservation organisation, Sea Shepherd Global, has formally called on Hong Kong authorities to take strong action after whale meat was found in local supermarkets last week.
Sea Shepherd Global Asia Director Gary Stokes, a DB resident, has written today to the Commissioner of HK Customs & Excise regarding the incident.
Around DB reported last week that the tins of whale meat curry were found for sale in the 759 supermarket chain, which has removed all tins of whale meat and apologized to its customers for selling illegal endangered species meat.
Gary said that wildlife crime is at the top of many countries political agendas, and that the action taken by Hong Kong authorities is being watched by the international community.
In his letter, Gary pointed out that Hong Kong is "one of the epicenters of the world's illegal trade" and it was important that any crimes found are punished to the full extent of the law.
"Both the store and the importer knew that Hong Kong is a signatory to CITES and that importing, possession or sale of whale meat or any other Appendix 1 listed species in Hong Kong is illegal," Gary wrote.
"Under Cap 586 of the Hong Kong Law they need to be arrested and prosecuted."

This application is related to U.S. patent application Ser. No. 11/197,924, "Storing a Sparse Table Using Locality Groups", filed Aug. 5, 2005, which application is incorporated by reference herein in its entirety.
This application is related to U.S. patent application Ser. No. 11/197,923, "Data Reconstruction from Shared Update Log", filed Aug. 5, 2005, which application is incorporated by reference herein in its entirety.
This application is related to U.S. patent application Ser. No. 11/197,922, "Data Compression of Large Scale Data Stored in Sparse Tables", filed Aug. 5, 2005, which application is incorporated by reference herein in its entirety.
The disclosed embodiments relate generally to data storage in distributed computer systems, and more particularly to data storage in sparse tables.
Table data structures, and particularly tables in database management systems, are used to store large amounts of data. The demand for efficient data storage for a variety of data intensive applications continues to grow. However, for many such data intensive applications, table data structures have been assumed to be an inappropriate mechanism for storing much of the data generated or obtained by those applications. Furthermore, there appears to be little appreciation that the paradigms associated with table data structures would be very useful in those applications.
For instance, the web pages downloaded during a crawl of the World Wide Web (WWW) are typically stored as a set of files, not as entries in a table or a database table. Similarly, RSS feeds (which can be considered to be documents) downloaded by RSS feed aggregators and other computers are typically stored as files. Storing web content, RSS feed content and the like as individual files is traditional and the mechanisms for managing and accessing such files are well established. The present invention, on the other hand, provides a data model and a set of data management processes and mechanisms for storing large amounts of data in one or more table data structures, thereby providing an alternative to the traditional model of storing individual content items in individual files.
Each of a plurality of data items is stored in a table data structure. A row identifier and column identifier are associated with each respective data item, and each respective item is stored at a logical location in the table data structure specified by its row identifier and column identifier. A plurality of data items is stored in a cell of the table data structure, and a timestamp is associated with each of the plurality of data items stored in the cell. Each of the data items stored in the cell has the same row identifier, the same column identifier, and a distinct timestamp.
In some embodiments, each row identifier is a string of arbitrary length and arbitrary value. Similarly, in some embodiments each column identifier is a string of arbitrary length and arbitrary value.
In some embodiments, a first set of data access permissions are associated with a first group of columns in the table data structure, and a second set of data access permissions are associated with a second group of columns in the table data structure. The first and second groups of columns are non-overlapping groups of columns and the first and second sets of data access permissions may differ with respect to the data access permissions granted to at least one user or group of users.
Like reference numerals refer to corresponding parts throughout the drawings.
The column family is the basic unit for controlling accessing to data. Thus, if the administrator of a table wants to restrict access to the contents in a first set of columns, but to allow unrestricted or less restricted access to a second set of columns, the columns in the first set are assigned to a first column family while the columns in the second set of assigned to a second (i.e., different) column family. As described below, the metadata for the table includes separate sets of security parameters (sometimes called access control parameters) for each column family of the table. When a column family has no access restrictions, the security parameters may either be set to default values, or in some embodiments, those security parameters need not be stored in the table's metadata at all.
The tablet is the basic logical unit of storage for purposes of distributing portions of a table across a set of files. Tablets are logical units of storage, as opposed to physical units of storage, because the content of a tablet may be stored in multiple files. In fact, as described below, even a relatively simple tablet will be stored in more than file (at least temporarily) if the content of the tablet is updated. Tablets are sometimes herein called data sets.
In some embodiments, each row identifier is a string of arbitrary length and arbitrary value. Similarly, in some embodiments each column identifier is a string of arbitrary length and arbitrary value. In other words, in these embodiments, there are no length limitations and no (or few) value limitations placed on row and column names or identifiers. In some other embodiments, restrictions may be placed on the value of a row or column identifier. For example, the column identifier string may have to comply with a rule that disallows use of particular characters or symbols, or that requires the use of only printable characters or symbols. The rule may further disallow the use of a particular printable character, such as the colon character, except as a separator between first and second portions of the column identifier. In some embodiments, column names are segmented into a column family portion and a qualifier portion (sometimes called the column portion), separated by a predefined separator character or symbol. For example, a column name may have format such as cf1:c2, where the colon is the separator character. In these embodiments, the column family name and the qualifier portion of a column name can each be arbitrarily long and have arbitrary value; however the column family name may have to comply with a rule that disallows use of the predefined separator character in the column family name and/or in the qualifier portion of the column name.
As shown in
Each server 154 also has a shared log 164, which stores update records reflecting changes made to the tablets allocated to that server 154. The shared log 164 is stored as a sequence of files, each of which is automatically replicated by a distributed file system so that instances (sometimes called replicas or copies) of the file are stored on at least three distinct servers 154. Similarly, each of the files that stores the contents of the tablets is automatically replicated by the distributed file system so that instances (sometimes called replicas or copies) of the file are stored on at least three distinct servers. As a result, when a server 154 fails, all of the tablet files and log files of the failed server are available on other servers of the system. When recovering from a server failure, the master 152 reallocates all the tablets of the failed server to other servers 154, preferably distributing the load associated with those tablets across many servers.
In some embodiments the table metadata 200 includes a record 202 for each distinct table stored in a single data center 150 (i.e., the distributed system of
In some embodiments, the tablet metadata 210 includes a record 212 for each distinct tablet stored in a single data center 150. Each tablet metadata record 212 may include a table identifier 214, the name of the last row of the tablet 216, an identifier or location 218 of the server to which the tablet is assigned (i.e., the server which handles access to and updates to the tablet), and a set of information 219 representing the state of the tablet. In some embodiments, tablet state information 219 includes a list of the files (see files 300, 302,
The range of rows included in any particular tablet is specified by the last row name or identifiers in two tablet metadata records 212: the record 212 of the particular tablet and the immediately preceding record 212 in the tablet metadata table. If the immediately preceding record 212 in the tablet metadata table has a different table identifier, then the current tablet is the first tablet of its table.
To locate the tablet that stores a specified row of a table, the tablet metadata 210 is searched or scanned until the first tablet metadata record is found that (A) has the same table identifier as the tablet and (B) has a last row that is equal (i.e., has the same value or sort value) or greater (i.e., has a higher value, or sort value) than the specified row. This record identifies the tablet that stores the specified row, and the server location 218 specified by the record identifies the server which handles access to the identified tablet. In the embodiments where the tablet key is the table identifier and the name of the first row of the next tablet of the table, the record identifying the tablet that stores a specified row of a table is located by scanning the tablet metadata until the first tablet metadata record is found that (A) has the same table identifier as the tablet and (B) has a first row (of the next tablet) name that is greater (i.e., has a higher value, or sort value) than the specified row.
In some embodiments, the servers 154 and the master 152 of the data center may each maintain a cache of recently accessed tablet-to-location mappings. This may speed up the process of locating tablets by having locations for frequently accessed tablets more readily available.

In some embodiments, the data retention parameters 225 can include a parameter that specifies a maximum number of data items to be retained in each cell of the column family. Alternately stated, when a non-zero value maximum number is provided, and the data items stored in a cell exceed the specified maximum number, the oldest data items in the cell (as indicated by the timestamps or versions numbers of the data items) can be deleted or garbage collected until the number of items in the cell is reduced to the specified maximum number. The garbage collection of excess data items need not occur immediately, and thus may be performed at scheduled times or whenever the load on the server falls below a predefined level.
In some embodiments, the data retention parameters 225 can include a parameter that specifies a maximum age (also called an age limit) of data items to be retained in each cell of the column family. Alternately stated, when a non-zero value maximum age is provided, and any of the data items stored in a cell have an age (as indicated by the timestamps of the data items) that exceeds the specified maximum age, those data items in the cell can be deleted or garbage collected. The garbage collection of data items whose age is greater than the specified age limit need not occur immediately, and thus may be performed at scheduled times or whenever the load on the server falls below a predefined level.
In some embodiments, the data retention parameters 225 can include a first parameter that specifies a maximum age and a second parameter that specifies a maximum number of data items per cell in the column family.
In some embodiments, the column family metadata may include security parameters 227 to govern access to data in any of the columns in the column family. For instance, these parameters may restrict access so that ordinary users have only read access to the data in the columns of the column family, while other classes of users, such as those with administrator rights, have both read and write access. The access rights for one column family in a table may differ from the access rights for another column family in the same table.
In some embodiments, the locality group metadata 230 includes a record 232 for each locality group of each distinct table stored in a single data center 150. Each locality group metadata record 232 may include a table identifier 233, the name or identifier 234 of a respective locality group, a field 235 indicating the maximum number of files used to store the locality group, and a set of compression parameters 236. The locality group metadata records 232 may optionally include a set of Bloom filter parameters 237, and may optionally include additional fields, such as a location flag 241. In some embodiments, the compression parameters 236 include one set of compression parameters 238 for compressing the data values in a locality group, another set of compression parameters 239 for compressing the key values in a locality group, and yet another set of compression parameters 240 for performing a secondary compression of the result produced by compressing the data values and keys. In some embodiments, a key value may include a string of four values such as r.cf.c.ts, where "r" represents a row identifier, "cf" represents a column family name or identifier, "c" represents a column name or identifier and "ts" represent a timestamp or version number or version identifier. As described in more detail below, the values in a table data structure may be stored as key-value pairs, where each key identifies the location of the value in the table, as well as the timestamp or version number of the corresponding value. Every key in a table, tablet or locality group is unique with respect to all the other keys in the same table, tablet or locality group. In some embodiments, the locality group metadata 230 is stored on a per-table basis and may be stored together with the table metadata 200 and the column family metadata 220. In these embodiments, the table metadata 200, column family metadata 220 and locality group metadata 230 for each distinct table are stored together in a corresponding metadata file.
The optional Bloom filter parameters 237 are provided when a Bloom filter is used to block attempts to access non-existent entries in the locality group. In some embodiments, when Bloom filters are used with a locality group, the Bloom filters are stored in each of the files used to the store the locality group (i.e., each file includes its own Bloom filter). Every time an item is added to the locality group, within a particular tablet, the key of the item is hashed and used to update the Bloom filter. Whenever an attempt is made to read the item corresponding to a specified key, the Bloom filter is checked to see if the locality group, within the particular tablet, contains or may contain the item. If the Bloom filter returns a negative result, the item is known to not be present in the locality group of the particular tablet, while if the Bloom filter returns a positive result, a value corresponding to the key is likely (but less than 100 percent certain) to be found in the locality group of the particular tablet. The Bloom filter parameters 237 may specify which of the locality group's files have Bloom filters. In some embodiments, the Bloom filter parameters 237 may also specify the number of hash functions to be used and/or the size of the Bloom filter array, while in other embodiments the number of hash functions and the size of the Bloom filter array are automatically determined.
The location flag 241 may be set or reset by a user to designate a locality group for loading into and keeping in volatile memory. For example, if the flag 241 for a locality group is set, then the locality group files corresponding to that locality group are loaded into volatile memory and kept in the volatile memory until the flag is cleared. If the flag 241 is cleared, then the locality group files corresponding to that locality group are not kept in volatile memory. Keeping locality group files in volatile memory may help speed up operations that access the files. It should be appreciated that the shared log is not affected by the state of the location flag.
Whenever a compaction trigger event occurs (e.g., episodically, when the memory of a server reaches a predefined level of fullness, or the memory state array 310 reaches a predefined size or level of fullness; periodically, when the passage of a time since a last compaction reaches a predefined threshold; upon a split or merge of a tablet; upon the unloading of a tablet; and/or upon user request), the update information in the memory state array 310 is used to generate new update files 302 for the locality groups for which the memory state array 310 contains updates. If, as a result, the number of files for a locality group exceeds the maximum number of files allowed for that locality group (as specified by either the metadata for the locality group, or by a default value), then two or more of the update files 302 are combined so as to reduce the number of update files 302. In an alternate embodiment, when the number of update files 302 is already at its maximum allowed value for a locality group, the update information in the memory state 310 is added to the newest of the update files.
When performing a "compaction," which means combining two or more locality group files 300, 302, if the same key is found in two files 300, 302, then the newer value for the key is retained and the older value is discarded. If the newer "value" is a deletion, all older values for the key are discarded if the compaction compacts to the base file. If the compaction does not compact to the base file, the deletion "value" is retained.
In some embodiments, a compaction trigger event may trigger either a minor compaction or a major compaction. For example, a minor compaction is triggered when a server's memory reaches a predefined level of fullness. Memory fullness may be based, for example, on the total amount of data stored in the memory state arrays 310 for all the tablets hosted by the server. When a minor compaction is triggered, the server identifies one or more tablets whose memory state arrays have the most data in them, and then writes the information from each of those memory state arrays 310 into one or more locality group files 302. The memory state array 310 is then re-initialized to a predefined empty state. In some embodiments, the minor compaction is performed on successive tablets until the fullness of the server's memory falls below a predefined threshold level of fullness. In other embodiments, each minor compaction trigger event causes only one tablet's memory state array 310 to be converted into one or more locality group files 302. The tablet whose memory state array 310 is converted is selected based on the amount of data stored in the memory state arrays 310 of the tablets hosted by the server, or on a round robin ordering of minor compactions, or on any other appropriate selection mechanism or rule. As noted above, a minor compaction may also include merging locality group files 302 when the number of locality group files for any particular locality group exceeds the maximum number of such locality group files specified for that locality group.
A major compaction is the combining of the base file 300 and all the update files 302 of a locality group so as to form a new base file 300. In some embodiments, a major compaction is triggered periodically, for instance once per day. In these embodiments, a compaction thread is launched upon the triggering of a major compaction. The compaction thread performs a major compaction on the locality files of each tablet, one locality group at a time, within one tablet at a time, until the sets of locality group files of all the tablets hosted by the server have been compacted to form new locality group base files 300. In some other embodiments, major compactions are performed on the locality groups of a tablet, one at a time, in round robin order during successive compaction events. Periodically compacting all the locality group files 300, 302 of each locality group into new base files helps to keep access to the data in the tablets efficient and ensures that deleted data are eventually removed from the system.
In an alternate embodiment, the server 154 includes a separate memory state array 310 for each locality group of each tablet hosted by the server 154.
Each tablet or data server includes a shared log 164. Whenever an update is made to a tablet hosted by the server 164, the update is first committed to the shared log 164, and only when the update is know to be committed to the shared log 164 is the update applied to the memory state array 310. The shared log 164 is stored as a sequence of sub-log files 320. In some embodiments, new updates are added to a current sub-log file 322 until the sub-log file reaches a threshold size, or until a new addition to the current sub-log file 322 would cause the size of the sub-log file to exceed a threshold value. At that point, the current sub-log file is closed and a new sub-log file is created and becomes the current sub-log file to which new updates are added.
The shared log 164 stores a sequence of update records. Each update record indicates a new value for a specified key; the deletion of the value (if any) at a specified key; the deletion of a cell at a specified row and column; or the deletion of an entire row. In some embodiments, a single update record may indicate the deletion of a subset of multiple versions of data values at a cell.
In some embodiments, the tablets, column families, and locality groups are non-overlapping. This means that that a row cannot belong to two tablets at the same time and a column cannot be assigned to two column families or two locality groups at the same time; the ranges of rows between tablets are mutually exclusive and the ranges of columns between column families or between locality groups are mutually exclusive. For example, if a table has rows A, B, C, D, E, the table has two tablets, and a first tablet of the table contains rows A, B, C; then the second tablet contains rows D, E and cannot contain rows A, B, or C because rows A, B, C already belong to the first tablet. As another example, if a table has columns P, Q, R, S, T, the table has two column families, and a first column family of the table contains columns P, Q, R; then the second column family contains columns S, T and cannot contain columns P, Q, or R because columns P, Q, R are already assigned to the first column family.
In some embodiments, a data or tablet server 154, as shown in
As described elsewhere in this document, memory 410 of a data or tablet server may also store a number of files and data structures, including tablet files (i.e., locality group files 300, 302), one or more memory state arrays 310, and shared log files 320, 322. Optionally, memory 410 may also store one or more metadata tablets 170, each of which may include one or more sets of locality group files.
Each of the above identified elements of
The foregoing description, for purpose of explanation, has been described with reference to specific embodiments. However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.

They may have done better than they have done better than they have before in their council elections but they have come nowhere near winning a general election. In London they came fifth just after the BNP whilst the Greens done better than ever by coming third they didn't do so well in Liverpool either. The only mayor election they did marginally well is in Salford again hardly enough to win an election.(Original post by HeyyImRyan)
Evidence from the May elections and opinion polls says otherwise, more and more people want an EU referendum and know that no other party will give them it.
Of course Greens don't stand much chance either but they are a slightly ahead of UKIP so by saying they're a party no on takes seriously you're basically saying UKIP are too. It's a vocal minority who feel that strongly on an EU referendum they'll make it their sole reason for voting for a party especially seeing as there are talks of Labour offering it now.
The only place I've seen where there even slightly popular is on here and even so The Conservatives, Labour and the Lib Dems are more popular.
Unfortunately, we'll only see Labour and The Conservatives at the helm for a very long time especially seeing as now the Lib Dems have screwed themselves over. The only chance UKIP have is a possible coalition with the Conservatives but even that's a very long shot and probably have the same chance as the Greens have of building a coalition with Labour.
Am I the only one who likes The Green Party?

Today's top ten...and I love it....
Top Ten Most Frustrating
(and/or Annoying) Characters EVER:
(and/or Annoying) Characters EVER:
Note: I have extending the topic of my list to include annoying characters, too. I know that many people will not agree with me, but...oh, well! I will be ordering these as a true top ten for me...so, I will lead up to my #1 most frustrating character. :)
(Lily Dale in A. Trollope's The Small House at Allington. Ugh. Source: Public Domain.)
(Lily Dale in A. Trollope's The Small House at Allington. Ugh. Source: Public Domain.)
10. Peeta Mellark from The Hunger Games. I just don't like him that much. He bores me.
9. Stone Barrington from Stuart Woods's Stone Barrington novels. Why? Read here.
8. Alice Quinn in The Magicians. A Hermione Granger wannabe. I really dislike her.
7. Lavender Brown in Harry Potter and the Half-Blood Prince. Reasons clear enough.
6. Lily Dale in The Small House at Allington. Ugh. This one. She is so clueless and just stagnates.
(Pip in C. Dickens's Great Expectations. Get a clue, kid. Source: Public Domain.)
5. Pip in Great Expectations. Pip. PIP. Get a freakin' clue. He is so annoying!! "ESTELLA!!!"
4. Melanie Hamilton Wilkes in Gone with the Wind. There is no reason to "be good" and put up with crap all of the time. I want her to get over her southern belle training and kick some people out.
3. Callie McFay from The Demon Lover. SO PRETENTIOUS. I couldn't finish the book because of her...not good, considering she is the main character.
2. Christian in The Pilgrim's Progress. Talk about a whiner and someone who is clueless. I'm sorry, but this book is just the worst. And Christian is a big part of that. So is the author, who loves to give Christian noble sins to deal with, but chooses to give Christian's wife sexual sins to deal with...because we all know that women had so much privacy to commit sexual sins way back in the day. What a jerk.
1. Anastasia Steele in Fifty Shades of Grey. I'm all for fantasy, but the middle-schoolish plot, writing, and character development in this book is appalling. I really don't like any person in this book, but I especially don't like Ana. For so many reasons. Most of all, I can't stand that the author even created her and decided to use her character to perpetuate the horribly dangerous myth that a woman, with enough patience and understanding, can reform an abusive and damaged man. Real life example "A": Rihanna. Mark my words. It is going to happen again.
