Two rival wizards. You can guess what happens. Yes, one flays the other naturally, but is interrupted half-way through the skinning ritual...
One of the preeminent occult scholars of the Cosmic Era, well versed in ancient mysteries, and one of the hidden masters manipulating the Cosmic Era.
Each new home prides itself on its idol and as each new home receives its idol, the power within them grows, glows and connects. ...They are the bringers of wonderment and gifts but little do the townsfolk know, for the Shithiran are the takers of everything.
Pnathic sorcery has existed for ages, crudely used by magi who no idea the true forces they were fumbling with.
"a new (scientific) truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it."
Max Planck

A small group of men stares intensely at something. Coming nearer, you see puppies, obviously still young, as they are small and only learn to walk. Cute as they are, the men look serious and exchange a comment here and there, making their mother nervous. But one man keeps her somewhat calm, while looking with others on the little ones.
The puppies are a completely new dog breed. The breeder hopes for better characteristics, the other men are mostly hunters and other dog-fanciers, that were called or came from own interest. If all looks well, they will have business. But now, they are just watching.

Published: Saturday, September 22, 2001 at 6:01 a.m.
Last Modified: Friday, September 21, 2001 at 11:00 p.m.
Vandebilt Catholic High School jumped out to a 35-0 lead at the half and cruised to a 49-0 non-district win over Riverdale on Friday in Houma.
The Terriers (2-2) rushed for 285 yards in the game. Starting quarterback Adam Haydel rushed for 46 yards and two touchdowns. He started the scoring with a 25-yard run in the first and added a 13-yard score with 51 seconds left in the third quarter. Haydel and John Gordon split time at quarterback.
"We have two good athletes at that position," Vandebilt coach Brad Villavaso said. "It makes other teams plan for both of them."
Bennett Porche's 24-yard touchdown run was the second VCHS score of the first quarter. With 10:28 left in the first half, Brady Drapekin scored on a 32-yard run. Ryan Rome added a 70-yard punt return for a touchdown and Quinton Allen scored on an 8-yard run on the final play of the first half.
Porche finished with 69 yards on six carries. Drapekin had 70 yards rushing on five attempts. Allen finished with 48 yards on five carries.
"The kids had fun after a tough loss last week. The kids came back as a team and I'm proud of them," Villavaso said.
The Terriers lost to Terrebonne, 14-13, in overtime last week. VCHS led in first downs, 15-11. Vandebilt also held a 315-188 advantage in total yards. Riverdale (1-3) rushed for 161 yards and passed for 27 yards.
Haydel and Gordon combined for to complete one pass in five attempts.
Chris Breaux closed out the scoring for the Terriers when he intercepted a pass and returned it 90 yards for a score.
Shane Henry was busy for the Terriers as he recorded seven extra points. Each team lost a fumble in the game.
Riverdale has lost 32 of its last 33 games.
Vandebilt will play host to Bishop Sullivan next week.

AGAIN!2nd time in a (half) year.Tomorrow back to $5,00.
THIS is how they grow their business. Sure it will take a downturn in the morning but gotta look to the future. They've already confirmed their business is getting stronger and they've announced a great dividend increase. Apparently they've ascertained some great investment opportunities and want to act. As long as the dividends keep coming I have no problem just sitting on my shares. Tomorrow will most likely be a great buying opportunity. Hmmmmmmmmmmmmm.
Bob:you are right. I have to look further than tomorrow.Although, it is the second offer in 6 months!I learned something tonight:If a stock is raising quiclky it can be sign that there is coming a public stock offering; io a SELL SIGNAL.

Keep the Opportunities, Lose the Opportunists
Researchers Now Have a Myriad of...
Loss of Lives in Clinical Trials...
Clinical-Style Validation, Regulation, and Quality Control...
Led by the Biotechnology and Biological Sciences Research Council (BBSRC), the U.K. Research Councils will award £10 million (approximately $16.64 million) to establish five centers for DNA synthesis across the U.K. to further develop the country's research base in synthetic biology.
In addition, £2 million ($3.33 million) will provide equipment to enhance student training in DNA synthesis at BBSRC and Engineering and Physical Sciences Research Council (EPSRC) Centres for Doctoral Training (CDTs), which provides training environments for students of synthetic biology.
According to BBSRC, the new academic centers will aim to bring together academic and embryonic synthetic biology companies, contributing to the U.K.'s growing synthetic biology industry to help create jobs and drive economic growth. The centers will be in Edinburgh, London, Liverpool, Norwich, and Cambridge.
The CDTs, based at University College London and a consortium between the universities of Bristol, Oxford, and Warwick will offer doctoral students the chance to learn in specialist synthetic biology facilities.
"These new investments will help the UK develop as a leader in synthetic biology and make advances in a wide range of fields, such as agriculture, renewable materials, biofuels and medicines, while at the same time reducing our reliance on finite resources, such as petrochemicals," said Melanie Welham, BBSRC executive director of science. "Nature's toolbox already produces many useful industrial chemicals and medicines and synthetic biology offers the opportunity to redesign these tools for useful purposes."

Spondon is a ward in the east of the city of Derby. The original village dates back to the Domesday Book but the area became heavily industrialised in the 19th and early 20th centuries, with companies such as British Celanese (now Celanese Corporation) who made cellulose acetate in World War I and later artificial fibres.
The name Spondon is Anglo-Saxon and describes a gravelly hill. The village is mentioned in the Domesday Book of 1086.[2] In about 1333,[3] a great fire, starting at The Malt Shovel, a local pub, and aided by an easterly wind, swept through the village destroying the church and all but a few houses, with just one casualty, the mayor. The damage was so great that a judge, Roger de Bankwell, was sent to hear pleas for relief from taxes.[3] The Great Fire of Spondon is still commemorated and taught as part of the curriculum in local schools. A village fair was held on its 650th anniversary (circa.1990).
Spondon is part of the Mid Derbyshire constituency for Westminster elections.
The community lies on the north slope of the valley of the River Derwent east of Derby and is divided by the A52, which separates the residential Spondon village area at the top of the hill from the heavily industrialised area at the bottom.
At the census in 2011 Spondon had a population of 12,377 of which 94.6% were White British, compared to 75.3% for Derby as a whole.[1]
The industrial belt lies to the south of the Nottingham Road (an old Roman road) as does the canal and the railway. These barriers separate the residential three quarters of the village from its industrial quarter. The various industries have included a dye works, electricity generating station, two scrapyards, sewerage works, British Celanese synthetic fibres works and a tannery.
Spondon holds a small number of chain shops but continues to support the business of many independent tradespeople too, including a men's barbers, a gift shop and a bakery. Chapel Street and Sitwell Street (in the centre) are the main areas of this retail activity. Dale Road (north-east) and Nottingham Road (south) also have a row of shops. Superstores (Asda off Nottingham Road (south-west) are also in Spondon.
Culture and community[edit]
There are many clubs/groups/societies serving Spondon. The Spondon Village Festival (Carnival) was first held in 2010 and is hoped that it will become an annual event combining carnival and fair. Spondon won the Urban Community award from Britain in Bloom in 2005.
Facilities - one library, two social clubs, six public houses (the names and numbers have not changed since 1961).
Parks - Brunswood (playground + playingfield), Dale Road (field + landscaping), South Avenue Rec (playground + field), Gravel Pit Lane (playingfield), Locko Park (country park), Spondon Woods (woods + scrub), Stony Cross (woods + scrub), Willowcroft (playing field) .
Venues - Asterdale Club (formerly the Celanese Workers' Club), club grounds, village parks, village hall, old school hall.
The historic centre of the village is designated as a conservation area. Locko Park is a Grade II*-listed mansion dating from 1669. The Homestead is a large detached Georgian mansion on Sitwell Street. The Stone Archways in Park Road mark the entrance to the now demolished Spondon House. The Enoch Stone Memorial marks the spot on Nottingham Road where a notorious murder took place in 1856.[4]
Derby Canal (Derby - Sandiacre) opened in 1795, and enabled other industries. The canal closed in 1964. There was talk of reopening for leisure purposes, but without progress (in 2010).[5]
The Midland Counties Railway opened a line from Derby to Nottingham in 1839.[6] This line became part of the Midland Main Line to London St Pancras railway station. Spondon railway station has a rather limited service to both Derby and Nottingham.
The A52, 'Borrowash by-pass' recently named Brian Clough Way, cuts through the village and provides express road (dual-carriageway) links to the west (Derby) and the east (M1 and Nottingham). Regional Cycle Route 66 links Spondon to Chaddesden and Alvaston.
There are five state schools located in the village. Primary Schools - Asterdale (south-east), Borrowood (north-east), St.Werburgh's C of E and Springfield.
Secondary Schools - West Park School.
West Park School represents the merger by default (fire/arson, 28/01/2002) of the former Spondon School (seniors) (State Comprehensive) which was located on two adjoining sites. These sites being the 'upper school' (1960s, grey brick, concrete and glass) at the top of the hillside, the current site, and the 'lower school' (1970s, grey brick, brown tile, timber and glass) at the foot of the hillside, which burned down. The new name comes from the two roads which lead to it.
Religious sites[edit]
St. Werburgh's Church dates from around 1390, replacing an earlier church destroyed by fire in 1340.[7] In the churchyard is an Anglo-Saxon cross dating from c.870.
Spondon Cricket Club,[8] Spondon Dynamos Football Club.[9] Bowls club, Snooker club.

My stay of 3 nights was quiet and comfortable. The restaurants available at this hotel were very good and there were more restaurants nearby. Hotel is modern and tranquil - excellent!
breakfast staff did not understand me, twice. They got me something I did not order.
The room decor, bathroom are excellent.
Nothingi in particular.
New with large best furnitures rooms, Near to the Shopping Centers.
WiFi at the room difficult to connect.
Great design , decoration location and decoration.
The garden and cafe on roof floor
windows.need.to be sound prof , the disco downstairs bass wont let u sleep
Bennigans was the only part of the hotel where staff demonstrated good customer service and efficiency.
The breakfast buffet can only be described as appalling. It was chaotic, the food was invariably cold and inedible and of a very poor quality and there was a constant stream of complaints from guests that were ignored ona daily basis, several families just left the cafe .When we used the room service it took 5 phone calls over a period of 2 hours to have one salad delivered. The review does not accuratley display what is and isnt provided. No mini bar, no hairdryer, no iron or board and no extras as advertised such as robe etc.Lack of ANY facilities for children. The cleaning was very poor..
Great place to take a little three day break from the grind. Perfectly relaxing.
The hotel opened in Sept 2010 and was therefore very new when I stayed. The staff are very helpful and attentive. The pool area is small but the spa is very good, again the staff are great.
The bar facilities are not suitable for a relaxing drink. Definately not a family hotel.
In my opinion best hotel for this price.
What I liked best about my stay was the initial greeting and hospitality illustrated by the front desk staff, I was made to feel as if I was a VIP. They were very helpful and concerned about my well being while at the hotel. The hotel offers something for everyone, they have good room service, a restaurant and bar is attached to the hotel out front, and there is a fantastic Indian restaurant attached to the rear, also the hotel has several clubs for entertainment inside. If you are wishing to just relax you can do so without being disturbed by noise from other venues. I recommend you stay here and see for yourself.
noyhing to complain about
This is a aparment for 4 people but utensils for only one
The place of the hotel
They have Coffee shop open for 24 hours and in reality it is not. Also, they have ask for entrance fee. As guest I'm suppose to pay. Why are they saying 24 hours and it not true.
There is big car parking area for the hotel. There are also restaurants, supermarket and shopping malls in walking distance from the hotel. The entertainment is very good for singles.
There was cigarette thrown at the room floor and was not cleaned before I check in. Also, the staffs for the night club and Arabic disco were very rude.
Room color
The cleaning, no coffee and tea, not providing room and bath room materials
Housekeeping, no houskeeping for two days, i called and ask for it., noise isolation, we hear cars noise every morning.Business center, there are only two computers, one of them works only. The printer is not working. It is not a 4 stars hotel!!!
Free wifi, location close to malls
Swimming pool was not clean and the jacuzzi too. The parking hard to get in and out. F
Here's why:
We're not the seller
At KAYAK we don't set prices, so it's not possible for us to guarantee what other companies are selling.
We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.
Why aren't prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.
More questions or if you have a bad price to report to us
Please send us an

Friday brought the arrival of Blake Lively and Ryan Reynolds to Italy's Queen of the Adriatic, as the couple showed up at the 2012 Venice Film Festival.
Local reports said they made a low-key arrival in an SUV before boarding a boat to wend their way through the city on the water.
Last week, the duo, whose one-year anniversary together is coming up, got an early start on the Gossip Girl's 25th birthday with a sweet celebration at Manhattan's Serendipity 3 restaurant.
Prior to that, they were spotted at the gym together.

Hey, I've recently moved and been very busy at work and am only now coming out of net hibernation. Sorry to take so long to respond. I don't know if your still working on this project but I do have comments, questions and ideas for CP2PC and Tristero. Mnet does have some CP2PC calls and I'm adding more now. We plan on having verison 0.7 out with a GUI that talks to the backend via xmlrpc using the cp2pc spec. Right now we have int cp2pc.asyncPutFile(string fileURI, bool immediate, bool allow_cb) int cp2pc.asyncGet(string fileURI, bool allow_cb) Stuff we had to extend on: # cp2pc.stat is not an call defined in the cp2pc spec, but the specs are # not at all clear how statPutFile / statGet are supposed to work struct cp2pc.stat(int asyncOpId) This struct looks like (python syntax): { 'type': 'get', 'filename': 'somefile.txt', 'description': 'Got 5 of 15 blocks', 'progressFraction': '0.15', 'progressBytes': '10', 'uri': 'mnet:xxxxxxxxxxxxxxxx', } description should be 'progressDescription' to be more in line with specs. We really should rename what we call 'cp2pc.stat' to 'mnet.stat'. I'm adding a simple triple based search engine, and thus I'm getting into the tristero stuff now. Also I have some questions/wishlist items: * some defined way for a p2p backend to say what types of URI it can handle. It maybe a list of statement in the "cp2pc:configuration" or other database. This would allow clients that are connected to a bunch of backends to route user request for a URI to the right backend. * We want to expose stuff like: what is the software running this backend, what version is it, what types of URI could I get/put, etc. Where do you suggest putting that info? I thought "cp2pc:configuration" is probably the best database to put it in, but it would be nice to have the docs back that up. * A backend autodiscovery protocol would be nice. I want to fire up my CP2PC gui and have it find my mnet, freenet, and mldonkey p2p backends and start getting status from them with no problems, and no configuration. We do this by having mnet start on localhost:7080, and if that's taken 7081, 7082 and so on. Our command line clients can detect them all. * You should point out in your docs that the best way to autheticate users who should be allowed access to the backend will be via http auth. Not some screwed up XMLRPC nightmare. * a API call that can shutdown the backend. * It should made clear when changes to the "cp2pc:configuration" database are to go into effect, right away (so make a group of changes with tristero.replaceAll(string uri, list oldList, list newList) ), or after some other call is made. * There should be a standard XMLRPC fault code for functions that change the database in some way to say "you tried to change a readonly value". Maybe there is some HTTP error code that says the same thing and we could copy that? * There are a lot of places in the spec where you seem to confuse C structs with XMLRPC structs. E.G.: > struct { > boolean completed; > /* fileURI */ string result; > } statGet (operationID opid); I would use a list here, where the first element of the list is a boolean and the second a string. * You need to exploit the power of hypertext in your docs. They could increase the accessablity of these docs. I'm looking forward to the world where other apps can access p2p backends in a simple, unified way. I'm ready to get out and push to make it happen. Thanks, myers

Hello, I've gotten to the point that I'm adding an XML-RPC interface to Mnet for publishing metadata to the "trackers", which search engines on the network. This is just a simple implementation to get the new version (0.7) feature comprable to the old version (0.6).

So I've been mukcing about with tristero tunnel and seeing if I can't hook one end into a servlet engine and then query the other end with a browser. I get a redirect screen from the servlet engine (tomcat) and then an exception from the tunnel: Received client connection java.net.SocketException: Connection reset by peer: JVM_recv in socket input stream read at java.net.SocketInputStream.socketRead0(Native Method) at java.net.SocketInputStream.read(SocketInputStream.java:116) at java.net.SocketInputStream.read(SocketInputStream.java:88) at tristero.util.Conduit.pump(Conduit.java:16) at tristero.tunnel.tcp.TcpTunnel$PumpThread.run(TcpTunnel.java:96) Now I'm guessing that this is because the servlet engine has told the browser to reconnect on a different port? and thus the browser has shut down the connection in order to try and make another one ..? I'd really like to be able to run HTTP over the tunnel. Anyone with any ideas? CHEERS> SAM

As regards NeuroGrid, it's enough work just getting the public-private key thing integrated.

in order to keep reputation on other peers, it is fundamental that every peer keeps the same peer ID over time. how do you assign a (unique) peerID to a peer? is this a problem in coping with other networks (such as Neurogrid, Mnet, ...) thanks a lot P.
Hi Brandon, Sam and everyone else, We have completed a new version of our CP2PC API. Below we have included an extract of the API which we think may be of interest to Tristero. We would like to incorporate these features into Tristero in some form. Can you let us know if you believe that they are useful. If not, what changes would you make? The following issues are covered: o Asynchronous operations. We propose to add asynchronous versions of many Tristero operations. These might be placed in separate Tristero interfaces, which Tristero components can optionally implement. Some of this was discussed on the mailing list previously. Most of the new operations that we propose are stated only in asynchronous form. The regular (synchronous) form can be easily deduced from the asynchronous form. o Putting, getting and deleting files. The Redirector interface can be used for get. However, there are currently no Tristero operations for putting and deleting. Using HTTP operations is not always going to be sufficient. o Extensions to the Tristero search interfaces. As previously discussed on the list, Tristero Search and SearchSet interfaces do not allow certain common boolean queries to be expressed in an easy way. The example query that appears under 'Example: Searching a P2P Network' below is such a query. Note that Sam's new search-related operations (fetchSubjects(string uri, integer value, string matchType) etc.) are useful for expressing fuzzy searches, but don't yet allow arbitrary boolean queries to be expressed. Also we have added a 'subscribe' method with which RDF triples can be monitored. We thought it would be better to start with the above subset of CP2PC. Other ideas that we have had are: o Using RDF triples to pass file attributes, as well as attributes that describe the progress (e.g. bytes downloaded) of an operation and other info about an operation. o Grouping files into collections. o Monitoring a Tristero component. o Configuring a Tristero component. o Local RDF databases for monitoring and configuration. o Joining and leaving a P2P network. o Distinction between network-wide file IDs and local file IDs. Note that although much of the CP2PC work is currently theory, we are working on an implementation of CP2PC. Links: o The entire CP2PC API from which this extract was derived: http://www.cs.vu.nl/pub/globe/cp2pc/notes/allnotes/cp2pc-api.v6.2 o Latest version of the CP2PC API: http://www.cs.vu.nl/pub/globe/cp2pc/notes/allnotes/cp2pc-api o CP2PC project home page: http://www.cs.vu.nl/pub/globe/cp2pc/.

Patrick =================================8<========================================= Preliminary ----------- We're using the term 'client' for the caller of the API. In the CP2PC case that would be an application with a user. The API is implemented by a 'Tristero component' Anything in square brackets ([]) is comment. Asynchronous Operations ----------------------- The API allows operations to be performed asynchronously. We distinguish between 'high-latency operations' and 'low-latency operations'. A high-latency operation is allowed to perform wide-area communication (e.g. access the Tristero network), and other work that takes a comparable length of time. A low-latency operation can only perform local operations (e.g. access the local file system and local networks). The distinction is somewhat vague. Many operations may have high latency. To avoid blocking the client while a high-latency operation is performed, the API provides asynchronous calls for high-latency operations. For example, if 'foo' is a regular, synchronous, high-latency operation: string foo(string p1, int p2); Then the asynchronous version of 'foo' is: operationID asyncFoo (string p1, int p2, boolean allow_cb); struct { string aResult; // corresponds to the return value of 'foo' boolean completed; } statFoo (operationID opid); 'asyncFoo' starts the operation and returns immediately with an operation ID. 'allow_cb' suppresses callbacks if it is 'false'. Results can be obtained by invoking the 'statFoo' method. 'completed' indicates if the operation has completed. Depending on 'completed' the the other returned value(s) will be final or intermediate results. Callbacks --------- The client implements the following callback interface, which is used by all asynchronous operations: void statusChanged (operationID opid); void statusChangeList (operationID opid, list deleted, list added); void completed (operationID opid); The 'statusChanged' callback operation is invoked whenever any of the (intermediate) results of the 'asyncFoo' operation have changed. The 'statusChangeList' callback is an alternative to 'statusChanged'. It has the same semantics, but passes a list of changes to triples (see 'Subscribing to Database Changes'). 'statusChangeList' is only used in special cases. The 'completed' callback signals the completion of the 'asyncFoo' operation. Following a 'completed' callback, no more callbacks will be made for this operation ID. Notes: o The 'asyncFoo' operation needs to know where to invoke callbacks (e.g., which function or method to call, where to send an RPC to, etc.). We assume that the Tristero component and the client are somehow 'bound' together at initialisation time, i.e. have been initialised with each other's addresses (e.g. reference to objects, URLs). Asynchronous 'Utility' Methods ------------------------------ void cancel (operationID opid); void wait (operationID opid); boolean isDone (operationID opid); The client can request that an asynchronous operation be terminated by invoking 'cancel', passing the operation ID. A client can wait for an asynchronous operation to complete (possibly following a call to 'cancel') by invoking 'wait'. This is particularly useful when combined with suppressed callbacks ('allow_cb' is false), as it allows asynchronous operations to be invoked in a synchronous way. The 'isDone' method tests whether an asynchronous operation has completed. Publishing Files ---------------- operationID asyncPutFile (uri src, boolean immediate, boolean allow_cb); struct { boolean completed; uri dest; } statPutFile (operationID opid); The 'asyncPutFile' operation publishes a file to the P2P network. The file content is taken from 'src', which can point to a file in the local file system (e.g. a 'file:' URI) or somewhere else (e.g. an 'http:' URI). 'immediate' is a boolean which specifies whether the current contents of 'src' must be used as file content, or whether the Tristero component is allowed to fetch the contents of 'src' at a later time. If 'immediate' is true, then the Tristero component must publish the current contents of the file identified by 'src' to the P2P network. Changes to the contents of the file identified by 'src' (or the removal of this file) do not affect the published content. If 'immediate' is false, then the Tristero component is allowed to store 'src' as a reference and retrieve data from the file later. A URI under which the file was published is returned (in 'dest'). An invalid URI is returned if the URI has not been determined yet. If 'completed' is true then the returned URI must be valid. [ The 'src' argument will typically be a 'file:' argument if a file system is shared by the client and the Tristero component. However, we wish to allow for the case that these components do not have a shared file system. In such a case, an 'http:' or other scheme might be used. ] Unpublishing Files ------------------ operationID asyncDeleteFile (uri fid, boolean allow_cb); struct { boolean completed; } statDeleteFile (operationID opid); The 'asyncDeleteFile' operation unpublishes a file previously published (using the 'asyncPutFile' operation) to the P2P network. Downloading Files ----------------- For downloading a file we use an asynchronous version of the Tristero Redirect.get() method: operationID asyncGet (/* uri */ string src, boolean allow_cb); struct { boolean completed; /* uri */ string dest; } statGet (operationID opid); The 'asyncGet' operation downloads a file published on the P2P network by some peer (possibly the calling client). The file to download is specified by 'src'. This is the URI under which the file was published. The Tristero component stores the downloaded content in a local file. A reference to this file is returned in 'dest'. [ This operation is intended to perform the actual download from the P2P network, and to create a local copy of the file (local to the Tristero component). Although 'dest' may (for example) be an HTTP URI (e.g. in the case that the Tristero component and the client do not share a file system), it must not be a reference into the P2P network. ] Extensions to Tristero Search Interfaces ---------------------------------------- 'getSubjects' and Friends ------------------------- string getSubjects (string statementsURI); string getPredicates (string statementsURI); string getObjects (string statementsURI); The above operations take a URI for a list of statements and return a URI for a list of strings. The result of 'getSubjects' consists of those strings that appear as a subject in any of the 'statementsURI' statements. 'getPredicates' and 'getObjects' behave in a similar way. An example appears in 'Example: Searching a P2P Network'. The 'expand' Operations ----------------------- string expandSubjects (string subjectsURI, string statementsURI); string expandPredicates (string predicatesURI, string statementsURI); string expandObjects (string objectsURI, string statementsURI); The above operations take a URI for a list of strings (such as returned by getSubjects()) and the URI for a list of statements, and return a URI for a list of statements. The result of 'expandSubjects' consists of those statements in the 'statementsURI' list that have as their subject one of the strings in the 'subjectsURI' list. 'expandPredicates' and 'expandObjects' behave in a similar way. An example appears in 'Example: Searching a P2P Network'. The 'intersection' Operation ---------------------------- We extend the semantics of 'intersection' to not only work on statement lists, but also on string lists. An example of why this is useful may be found in 'Example: Searching a P2P Network'. Subscribing to Database Changes ------------------------------- operationID subscribe (string searchURI, boolean ignoreExisting); The 'subscribe' operation can be used to receive changes to the set of statements that match a search query. (In CP2PC we use this to monitor statistics etc.) 'subscribe' is an asynchronous operation that does *not* follow the pattern described in 'Asynchronous Operations'. The 'subscribe' operation uses the 'statusChangeList' callback rather than the 'statusChanged' callback. (See section on 'Callbacks'.) Each call to 'statusChangeList' summarises the changes that occurred to the set of matching statements since the previous call to 'statusChangeList', if there was such a call. The first call to 'statusChangeList' passes changes since 'subscribe' was called (if 'ignoreExisting' is true) or passes the entire current set of matching statements in the 'added' parameter (if 'ignoreExisting' is false). Changes are summarised as follows. 'deleted' is a list of statements that were removed, and 'added' is a list of statements that were added. The 'completed' callback signals the completion of the 'subscribe' operation. The 'subscribe' operation can be terminated by calling 'cancel'. 'wait' and 'isDone' are not defined for 'subscribe'. Asynchronous Execution of a Search ---------------------------------- operationID asyncExecuteSearch (string searchURI, boolean allow_cb); struct { boolean completed; string resultsURI; } statExecuteSearch (operationID opid); In CP2PC context, Search and SearchSet always have low latency. Fetch, however, may have high or low latency depending on whether the query is on a local or a remote database. We introduce the 'asyncExecuteSearch' as a means to execute a query asynchronously. The results are placed in a local 'results' database whose URI is returned as 'resultsURI'. The results may be read from the results database using Fetch and 'resultsURI'. Since the results database is local, this is guaranteed to be a low-latency operation. The 'asyncExecuteSearch' uses the 'statusChangeList' callback in the same way as 'subsribe'. An example appears in 'Example: Searching a P2P Network'. Example: Searching a P2P Network -------------------------------- As an example, consider a user that searches for a file that is an audio file and contains the song "Oops I did it again" by the artist "Britney Spears". The user would also like the file to be encoded at 128Kbits/s or higher. After acquiring all this information from the user, the client would perform the following steps. 1. A search query is formulated: titlesURI = search("", "title", "Oops I did it again", "cp2pc:network"); authorsURI = search("", "author", "Britney Spears", "cp2pc:network"); typesURI = search("", "type", "x-audio/*", "cp2pc:network"); encodingsURI = search("", "encoding", "128", "cp2pc:network", ">="); filesURI1 = getSubjects (titlesURI); filesURI2 = getSubjects (authorsURI); filesURI3 = getSubjects (typesURI); filesURI4 = getSubjects (encodingsURI); filesURI = intersection (filesURI1, filesURI2); filesURI = intersection (filesURI, filesURI3); filesURI = intersection (filesURI, filesURI4); // 'filesURI' represents a query for the file URIs that we are // looking for. This may be sufficient in some cases. However, // let's assume that the user is also interested in obtaining // the attributes that we have searched on: titlesURI = expandSubjects (filesURI, titlesURI); authorsURI = expandSubjects (filesURI, authorsURI); typesURI = expandSubjects (filesURI, typesURI); encodingsURI = expandSubjects (filesURI, encodingsURI); attributesURI = union (titlesURI, authorsURI); attributesURI = union (attributesURI, typesURI); attributesURI = union (attributesURI, encodingsURI); 2. The 'attributesURI' search query is optionally executed using asyncExecuteSearch(). Since searching a P2P network is a high-latency operation, this is recommended: opid = asyncExecuteSearch (attributesURI, true); // later, when the 'completed' callback is invoked: attributesURI = statExecuteSearch (opid).resultsURI; 3. The results are retrieved. files = fetchSubjects (attributesURI); Note that if step 2 was performed, this is a low-latency operation. 'files' is a list of URIs. In order to provide the user with more information about each file the application may then perform the following calls for each (unique) entry in 'files': sname = search (files[i], "name", "", attributesURI); name = fetchObjects (sname) [0]; stitle = search (files[i], "title", "", attributesURI); title = fetchObjects (stitle) [0]; sauthor = search (files[i], "author", "", attributesURI); author = fetchObjects (sauthor) [0]; sencoding = search (files[i], "encoding", "", attributesURI); encoding = fetchObjects (sencoding) [0]; Note that if step 2 was performed, these are all low-latency operations.

Other than that we have a couple more CP2PC specific methods (for joining and leaving a network) that should be async, but they won't affect tristero interfaces. With regards to the Fetch interface, in a previous mail, you (Brandon) sugested an execute() (except that we prefer to call it executeSearch()) method that performs the fetch and caches the results locally. This would be an async method leaving fetch() (and all its variants) to be synchronous. Also we are thinking of adding a subscribe() method to the Fetch interface. With this method you subscribe to a search query (URI) and receive callbacks/notifications whenever relevant statements are changed or added. This is useful to monitor system events, for example. Do you think this is useful? Finally, in order to use the async methods in a synchronous way we introduce a wait() method. The method takes the operation ID of an async operation and blocks until it is completed. It simplifies the interfaces because we no longer have to include synchronous versions of async methods. > It is a very good idea to define schema and publish them.

What else can > the Redirector interface be used for? Just curious. The Redirector interface for originally designed for URI->URL and URL->URI translation. For instance, you have a SHA-1 hash and you want to find out what the HTTP URL of a copy of that file is so you can download it. Or you've just put a file in your store and you want to use the file: URL to find the SHA-1 hash. However, the same interface can be used to a lot of different kinds of mappings. For instance, you could give it a HTTP URL and it could give you back a different HTTP URL where that file is mirrored. This interface is suitable to use for telling the network to download a file. One way to do this would be to have it take URIs for various networks, such as a SHA-1 URI for networks that support lookup by hash, and then return a file: URL saying where the file was stored. In the case that files are actually transferred in and out of the network, the method definitely needs to be async. On the other hand, sometimes it might not need to be, such as when the file already has a locally cached copy and the method only needs to return the file: URL to it. You can then use the returned URL to fetch operational attributes such as how far the download of the file has progressed. So the way I look at it, the documentation just needs to clarify that this file is always asynchronous with regards to the transfer of files. For instance, when you do a SHA-1 to file: mapping and get the file: URL, there is no guarantee that the file is already at the file: URI. Although it might be nice to have an additional method which allows you to block until the file arrives. So I propose that the Redirector interface be specified as async and that a new method is added prefetch(string url) which blocks until the given URL is entirely cached, if the implementation supports caching. > We suspect that many methods are latent enough to warrant > asynchronisation.

So we need to identify the methods which need to be async as making all the methods async would be unwieldy. So far we have identified Fetch and Redirector.

It is a very good idea to define schema and publish them. I don't actually care to define schema in the formal XML Schema or RDF Schema languages, although it would be cool if someone did that for us. My preferred schema documentation style is human-readable HTML documents in the style of the Dublic Core website, simply stating the name of the element and a brief description of what it does. It would be good to publish a schema for the operational attributes as well as the unified and network-specific file attributes. Developing schemas for these sorts of things is something we've been meaning to do for a while, but have been too busy with the interfaces. I'd be happy to collaborate on universal schema and adopt them as the official Tristero schema. > The monitoring interface is very simple at the moment.

It is actually just a subset of the Search API which supports just the addition and deletion of triples. It is attached as a slave to a real triple database and gets live updates when the db is changed. I eventually want to add methods to specify which triples to report and which to ignore. There also needs to be a schema for the various system events that go in P2P networks, such as making connections to other nodes. I currently have a component (soon to be in CVS if I fix my computer today) which receives triple updates and graphs the relationships of triple to each other, which given the proper schema would make a fine graph of the network. By the way, I seem to have lost the e-mail about adding an expand() function to the SearchSet API, but I think that it's a fine idea.

Remember? We went through it together on irc, and it worked on your computer, but there seemed to be something about my setup that screwed things up. I haven't had a chance to upgrade cygwin and try and sort this out yet. Either way there's nothing stopping me working on the tristero docs - just that it would be nice to be able to link them into the tristero.sourceforge.net site, and also that while I can't do the template building thing, I have to show people WebMacro templates, rather than html which can be confusing. Did you see the new Search document I posted to this list? It's mainly format changes, but there are a few additions. More soon. CHEERS> SAM

This design pattern is basically an application of transactions. You make modifications to your own overlay onto the main database and it takes a special separate method (with separate access permissions) to make your changes global. I would love to add transaction support to the API. I haven't so far because I didn't want to make the API daunting and I sure didn't want to implement transactions right now. However, with this new level idea it would be reasonable to add transaction support on a higher level. That would make the Tristero Search API draw closer to being a real database system. > The actual user identification is currently handled by cookies over > HTTP, which I guess is equivalent to what you suggest below about adding > authentication into the XML-RPC layer instead of the API, which seems > like the way to go. Session cookies are totally the way to do it for a browser-based interface to the database. It would be easy to hook such a system up to the underlying access control API. > p.s. is the cvs repository ok? (after my blunders of the other week) or > are you not in a position to check yet? I can do CVS checkouts on sourceforge but since they don't have a Java compiler there I can't actually try to build anything. I'm sure that anything messed up in CVS can easily be fixed though. That's the great thing about CVS! I'm trying to fix my computer today so hopefully I'll be back in the swing of things soon.

Nice! The execute method would need to have callbacks though, so that the caller knows when the operation is finished, and so that the caller may be notified of intermediate results, as they come in (see the CP2PC API). Would a synch version of execute() not also be handy? It allows you to 'freeze' results. This may be convenient in general. How about calling it 'execSearch', since in the future you might want to 'execute' other operations in the same way. Patrick

Just one small catch though. After an 'isolate' you have a list of entities, rather than a list of statements. It would be useful to convert ('expand') an entity list back to a list of statements, so that you can perform subsequent Tristero statement list operations on it, e.g.: // get statements from set1 that have subjects in set3 set4 = expand(set3, set1, "subject") // get statements from set2 that have subjects in set3 set5 = expand(set3, set2, "subject") set6 = union(set4, set5) where in 'expand(a, b, field)', 'a' is a list of entities, 'b' is a list of statements, and 'field' says which field of 'b' to match on. The above sequence has the same result as the intersectionBySubject we proposed. expand(set3, set1, "subject") is the equivalent of: result = empty set foreach subject in set3 s = search (subject, "", "", set1) result = union(result, s) So strictly speaking expand() is a convience method.

Yes, using the Redirector interface would probably work. However, we still need an asynch version of Redirector, since (in CP2PC context) Redirector.get would be responsible for downloading the file from the P2P network (plus see below). Is the Redirector interface specifically intended for this? What else can the Redirector interface be used for? Just curious. > > o We have extended a number of existing interfaces (used for CP2PC, > > i.e, Tristero Fetch interface, file-access interface, collection > > access interface) with asynchronous versions of the operations. > > In fact, we have defined only asynchronous operations for the new > > file-access and collection-access interfaces. > > That is very interesting.

We suspect that many methods are latent enough to warrant asynchronisation. In CP2PC we are considering a user application in which a user may want to have several downloads, uploads or searches (etc.) going at the same time. Having the application stall for one of these operations is not a good idea, since (depending on the P2P network) they may need to be executed across the Internet. Of course, you can solve this with threads as well. Another thing is that asynch operations allow intermediate results and progress to be returned. For example, you could track the progress of an Mnet download, as it contacts meta-trackers, block servers, etc. Of course in contexts other than CP2PC, synch versions may be more appropriate, in particular if it is known that an operation is short. In CP2PC we cannot really make that assumption since we need to allow for any P2P network. Tristero could offer both synch and asynch versions, in separate interfaces. In fact, we started out with synch operations and have now moved to asynch versions. Recovering the synch operations from the asynch descriptions should not be too difficult. > > o We have defined some file attributes that represent file > > meta-data.

Perhaps > give an example or two? Operational attributes are attributes that describe a particular invocation. An example of operational attributes that apply to many operations are progress-related: progressFraction -> progress of an operation in the range of 0.0 to 1.0 progressDescription -> progress of an operation as a human-readable string (e.g. 'contacting meta-tracker'). progressBytes -> The number of bytes downloaded so far, by a getFile (Redirector.get) operation. The operational attributes are stored as triples, in which the subject of a triple is an operation ID. The operation ID identifies an invocation (and is returned by the asynch invocation of the operation). As for file attributes, these are intended to describe things like file type, bitrate, author, performer, etc. of a file. We are thinking it would be a good idea to define a unified schema of file attributes, which can be mapped to each P2P network. Components implementing CP2PC/Tristero interfaces can translate back and forth between the unified schema and the network-specific schema. > > o In summary, the interfaces used are: > > Tristero search interfaces > > Tristero/CP2PC file-access interface > > (Tristero?)/CP2PC collection-access interface > > CP2PC configuration interface > > CP2PC monitoring interface > > I am interested in the configuration and monitoring interfaces as well. > I'm working on a logging API at the moment so that standard network > graphing and monitoring tools can be written to draw realtime pictures > of the network for quality assurance, debugging, and amusement.

The monitoring interface is very simple at the moment. It is a database of triples, with a schema, and (asynch) notification of updates. It may be sufficient though. Patrick
Brandon: I think your idea rocks. I hope implement access control that way instead of by putting identity-based access control schemes right into the RPC layer. Regards, Zooko

Hi Brandon, Just a note on how NeuroGrid currently handles multiple users. Rather than allowing users to actually delete individual triples, NeuroGrid maintains a seperate event table. When a user attempts to delete a triple, the triple remains, but an event is added indicating that the user has deleted that triple. Then when the user queries through the NeuroGrid interface, they no longer see that triple, but others still can. The NeuroGrid interface is sitting at a higher level and so which triples a user gets to interact with is dependent on the Event table. Thus users can ADD and DELETE triples from their own triple space as it were. They can also declare their own events public or private, which allows a user to maintain parts of their triple space and searchable by others, and part of it as private. That probably doesn't make much sense, and I really need to work on some documentation for this. I hope to propose some of the higher level NG functions as part of a Tristero interface. The actual user identification is currently handled by cookies over HTTP, which I guess is equivalent to what you suggest below about adding authentication into the XML-RPC layer instead of the API, which seems like the way to go.

My position has always been "support the interfaces you want", but that if you support an interface you need to support all of the methods in that interface. So for instance if you support fetch() then you need fetchSubjects() as well. I like this idea of grouping interfaces into levels of importance so that people have some idea of where to start. For the Search API, Search and Fetch would obviously be in the first level, Add and Update in the next, and SearchSet in the third.

Dr. Steve Greene is now sharing his reflections and practical insights as a ministry leader on Greenelines, a new podcast. Listen at charismapodcastnetwork.com.
I realize that we pastors are going way beyond motivational speaking in our sermons. We are sharing the gospel and leading people to the cross.
But we are still speakers and communicators nonetheless, and our effectiveness and influence depend on our understanding something about the nature of speaking.
Seth Godin, a marketing guru with much to teach the church, wrote about speaking and had this to say:
Speaking in public: two errors that lead to fear …
1. You believe that you are being actively judged.
2. You believe that the subject of the talk is you.
When you stand up to give a speech, there's a temptation to believe that the audience is actually interested in you.
This just isn't true. (Or if it is, it doesn't benefit you to think that it is.)
You are not being judged. The value of what you are bringing to the audience is being judged.
He goes on to say, "The members of the audience are interested in themselves. The audience wants to know what they can use, what they can learn, or at the very least, how they can be entertained."
This is truth. Seth is wise. Obviously, we are called to do more than simply please an audience. We are heralds of truth. But understanding what people are expecting or searching for when they sit down to listen to us certainly helps us communicate truth in a way that taps into the audience's interest.
I agree with Seth. Preaching isn't about you, so stop focusing on being the star, the celebrity, the eloquent master communicator out to impress your hearers. Instead, focus on the power of the gospel content to change lives now and for eternity.
The next time you preach, just before speaking, pray something like this:
God, help me to glorify You, honor Your truth and speak with the confidence that what I have to say matters. And help me to love these people enough to give them what I know they need—Your Word.
Brandon Cox has been a pastor for 15 years and is currently planting a church in northwest Arkansas, sponsored by Saddleback Church and other strategic partners. He also serves as editor of Pastors.com and Rick Warren's Pastors' Toolbox, and he authors a top 100 blog for church leaders.
