Я как бы слева, Нихил как бы справа. Изголяются Джеймс и Рич, соответственно. Рекс смотрит Джокондой.

Еще фото с PDC
Не мои, фотографировал коллега.
В-основном там фотографии с вечеринки в Universal Studio. Выкладываю для собственного удовольствия, под катом ничего интересного :)
PDC 2008 – гики в естественной среде
Это такой будет дыбровый пост, “о времени и о себе”, дневник наблюдений за живой природой и т.п. Session minutes я буду складывать отдельно и скоро даже покажу куда.
Фото есть, но меньше, чем хотелось бы. Пора копить две штуки баксов на пристойный аппарат.
PS Добавил возможность уведомления о комментах по е-мэйлу. Спасибо Богдану, он меня подвигнул :)
Ну что, вперед, под кат?

Вернулся с Microsoft PDC 2008 (Los Angeles)
Усталый, довольный, познакомившийся с кучей интересных людей. Впитывал информацию до закипания мозга. Добыл три книжки, две из них подписал у авторов. Участвовал в работе стола экспертов по метанию овец. (Все помнят, что я по призванию менеджер овцеметателей?)

Oct 27-30 – Microsoft PDC, Los Angeles
Официально заявляю, что там буду все три дня. Опознаете меня по шляпе.
ESRI Business Partner Conference & Developer Summit – Palm Springs, CA
В районе 17-20 февраля я там, скорее всего, буду присутствовать.
Также я, возможно, буду присутствовать на ESRI UC, так вот как-то.
Ищут программиста в Калифорнию

OpenID Authentication 2.0
GIS: как китайцы чинили перспективную коррекцию :)
http://cosmiclog.msnbc.msn.com/archive/2007/12/04/495870.aspx
Я думаю, дело было так: отсняли они кучу полос (сами понимаете, спутниковое фото – это одно длииииииииииииииииннное спагетти), а тут пришел чиновник и говорит – давайдавай, конференция про наш новый спутник будет через час!
А у них система новая, автоматизированного софта для перспективной коррекции еще нет, а ручками уж больно ломливо писать. Даже если существующий код присобачивать, трахаться как минимум неделю (просто потому что там на один снимок полтора десятка параметров приходится). А показывать-то что-то надо.
Ну, они тогда взяли фотошоп и сшили эти девятнадцать полос. Получили то, что получили – красивую картинку и международный скандал :) :)
update: Это я приврал. Софт у них есть. А было проще. (смотреть тут: http://www.planetary.org/blog/article/00001248/) Пришел чиновник и говорит – что это у вас на стыках хрень какая-то? Весь мир ведь смотреть будет! Надо чтобы красиво!
Ну, они тогда взяли фотошоп и… (далее то же, что и выше)
Silicon Valley CodeCamp 2007 is over!
Thank you, everyone!

Robert Hope [info] presents:
Generics from top to bottom [description]
Agenda: lists, generic methods, generic classes, anonymous methods, List vs ArrayList, using generics with Enum (again Reflection), using generics with Clone (again Reflection), IComparer vs anonymous delegate.
Nothing really new to me in theory, but some nice applications of generics.
Worth working with? Sure.
PS Tip: use of default(t)
PS Tip: to resolve the name: rclick-> resolve->using libraryname adds ‘using’ directive on top automatically. Cool.

Chris Mullins [info] presented:
Concurrency and threading with .NET [description]
Covered: available heap space on x86 systems, thread memory consumption, CLR-managed threads: ThreadPool pros and cons, Async I/O (see FileStream.BeginRead for sample code) pros and cons, timers, RegisterWaitForSingleObject, thread abuse (I wonder… ‘expanding down the WCF’ anyone?)
Did you know that .NET thread inside of lock() block is automatically promoted to ‘Above average’ priority by CLR?
Tips: When you create a thread, give the name to it. Makes life easier.
Tool: WinDbg and Son of Strike
Worth working with? Sure. As a matter of fact, I am going to invite him to ESRI (if my mgr approves) to give full versions of his presentations.
ALSO, VERY NEXT SESSION:
Chris Mullins [see above for info] presented:
.NET Garbage Collection [see above for descriptions]
Covered: generational garbage collection, Server CLR, Workstation CLR, Concurrent and NonConcurrent CLR modes.
Also covered: weak root references (useful for caching)
Useful info: Richter’s Garbage Collection column in MSDN
Also covered: abuse of GC.Collect() and memory fragmentation problem. CLR performance counters related to GC. Profiling memory leaks. Abuse of Finalizers.
Tool: Scitech Memory Profiler (the best)
Tool: Red-Gate Memory Profiler (expensive)
Tool: VSTS Memory Profiler (expensive, lousy, sometimes is good)
Tool: CLR Profiler from MS (free, you get what you pay for)
Tool: WinDbg, Son of Strike (use only as last resort)
Did you know that registering event handler actually creates a reference? Statics of that class and event handler itself are not deleted unless you do this in Dispose(). NOTE: Check for details
NOTE: COM and Win32 calls pin memory and create memory fragmentation.
Book: Jeff Richter “CLR via C#” and his other book. Also, check blogs of MS-ers on GC topics.

Anand Iyer [info] [MS] presented:
Create ‘Slick’ mashups with Popfly [description]
Requirement: Silverlight client installation, MS Live Id account
Well, it’s really ‘slick’ but kinda… proprietary-ish. For instance, all your mashups are stored|saved on popfly.ms. You can export them as sidebar widgets for Vista, however.
Unfortunately, I skipped session about Google Mashup Editor, so I really can’t compare right now.
Author’s blog: http://artificialignorance.net
Worth working with? Ok.

Mathias Brandewinder [info] presented:
Test Driven Development with NUnit [description]
Tool: NUnit
Advices to presenter: (1) calm down (2) stop moving the mouse erratically all over the screen (3) go less ‘beginner’ already.
Worth working with? Who knows…

Dave Nielsen [info] presented:
Mashup APIs and who’s using them [description]
It was not a workshop, more of a discussion panel.
I said to staff that they should introduce ‘discussion panel’ presentation type and move all these panels to the end of the day, to leave some time for the discussion itself. :)
(if you already know what the web service is, you can skip this post. I am giving this info for the sake of completeness)
API Types (broadly): Data, Service, Communications, Storage
API Formats (broadly): Name/Value pairs, POX (plain ol’ XML), REST, RSS\ATOM, SOAP\XML Schema, AJAX\JSON, Flex, Silverlight – and others.
API Catalogs (some): StrikeIron, XMethods, Programmable Web, API Finder, Remote Method, IBM SOA, eSigma
(I also add ESRI’s Geography Network)
Sample mashup link: http://housingmaps.com
Tool: Notepad2
Links: Dave is all over the Web :)
Любит поговорить.
Worth working with? Sure!

Deborah Kurata [info] [inStep technologies] presented:
Best kept secrets in .NET [description]
It’s actually ‘.NET hacks in Visual Studio, for VB and C#’.
Covered: Nullable and its use, Debug.Print (yes I know it exists, it’s just hard to get used to!), static member String.Format() (oh yeah I somehow missed this as well), ‘using’ with IDisposable objects, ‘active windows’ triangle button, some Reflection (binding to Enum etc), some anonymous delegates, using writeXML method of DataTable (cool for fast prototyping!), VS template files and SNIPPETS – using, creating, modifying :)
Also: Class Designer and its uses, Server Explorer window(Database-neutral – COOL! – I can even run and debug my stored procs there!)
Rumors: Lambda expressions are coming in Orcas. Also, unit testing is moved to ‘Pro’ version, which is great – we don’t have to buy special license for ‘VS for Testers’ anymore.
Disappointments: C# has a lot less snippets than VB.NET. This sucks. Better check for more snippets online.
Tool: latest VisualStudio
Links: check ‘Deborah Kurata’ on the Web, lots of useful info.
Worth working with? Sure!

Symon Chang [info] [BEA] was presenting:
Using WS-SecurityPolicy for Web Services Security [description]
A guy with heavy accent who finished every sentence with the ‘all right’.
Actual quote: “They made things really complicated, you know… because of security…”
keywords: WSS, WS-Policy, WS security policy, signed endorsed encrypted supporting tokens
Tool: MS Indigo Security Policy Configuration Editor
Conclusion: Beginning… ok, intermediate workshop, masked as ‘advanced’. Anyway, I got introduced to the standards, which is always useful.
Worth working with? Only if I paid for doing this. My accent meets his accent and… BOOM! :)
CodeCamp, Saturday, 9.15AM
Juwal Lowy[idesign.net] was presenting:
Demonstrating WCF – beyond the endpoints.
Pretty impressive stuff they made at MS… Not ‘superior’, but certainly some of that is very clever :)
When asked about possible performance problems, avoided answering it until I dropped the subject :)
keywords: WCF, service contracts, versioning, singleton across the galaxy, fault isolation per class level, build-in concurrency management, MQML, performance throttling through app.config
books: “Programming WCF Services” by Juval Lowy. O’Reilly 2007
links: http://www.idesign.net
Tool: .NET, WCF
Conclusion: Clever marketing, disguised as a programming workshop
Worth speaking to this person again? Definitely yes!
