PPL and TPL sessions on channel9

- by Daniel Moth

Back in June there was an internal conference in Redmond ("Engineering Forum") aimed at Microsoft engineers, and delivered by Microsoft engineers. I was asked to put together a track on Multi-Core development, so I picked 6 parallelism experts and we created 6 awesome sessions (we won the top spot in the Top 10 :-)). Two of the speakers kept the content fairly external-friendly, so we received permission to publish their recordings publicly. Enjoy (best to download the High Quality WMV): Don McCrady - Parallelism in C++ Using the Concurrency Runtime Stephen Toub - Implementing Parallel Patterns using .NET 4 To get notified on future videos on parallelism (or to browse the archive) stay tuned on this channel9 parallel computing feed.

L'inventeur du pi-calcul est mort, Robin Milner nous quitte à 76 ans

L'inventeur du pi-calcul est mort, Robin Milner nous quitte à 76 ans Robin Milner est décédé hier à Cambridge, où il fut professeur à l'Université (ainsi qu'à celles de Londres, Swansea, Edimbourg et Stanford). Informaticien anglais, il a fait trois découvertes principales dans sa carrière, qui ont largement contribué à l'évolution de l'informatique moderne et qui lui valurent de se voir attribuer le prix Turing en 1991 : - LCF, le premier système de preuves automatiques, utilisé pour démontrer automatiquement des assertions mathématiques - Le langage ML - La théorie d'analyse des systèmes concurrents (calculus of communicating systems, CCS) et son successeur, le pi-calcul RIP Robin...

X technology is dead

- by Daniel Moth

Every so often, technology pundits (i.e. people not involved in the game, but who like commenting about it) throw out big controversial statements (typically to increase their readership), with a common one being that "Technology/platform X is dead". My former colleague (who I guess is now my distant colleague) uses the same trick with his blog post: "iPhone 4 is dead". But, his motivation is to set the record straight (and I believe him) by sharing his opinion on recent commentary around Silverlight, WPF etc. I enjoyed his post and the comments, so I hope you do too :-) Comments about this post welcome at the original blog.

IE9 Beta

- by Daniel Moth

I've been using Internet Explorer 8 since the early pre-release bits, but I never tried IE9 until today – the day the Beta is available. I downloaded it from here: http://www.beautyoftheweb.com/ The download took longer than what I expected, but I was doing other stuff, so no bother. After coming down, it asked me to reboot my computer. Really hate when apps do that, but I did it anyway. The first time I launched it, it prompted me with a list of add-ons I should disable including the start-up time that I could save fore each one. It even let me configure the prompt so, for example, it won't prompt me again unless an add-on contributes to more than 1 second of the startup time. Cool. First thing I noticed is that the search bar had gone and, as you'd expect, you have to search from the address box. I totally despise this feature. The first thing I've been doing with all versions of IE is to turn off the automatic searching from the address bar and now I have no way of searching if I do that. Ridiculous. The second thing I notice is that the tabs are next to the address bar and cannot be moved to go below it. One word for that decision: appalling (and, no, I didn't accidentally drop an 'e' and added an 'l' in the previous word). The third thing I notice to the right is the favorites button (star icon) and when I click on it, it brings up the favorites explorer under it on the right; then I pin the explorer and it jumps to the left(!). Why move the entry point to this feature to the right instead of leaving it on the left is beyond me (other than wanting to retrain me on what I've been used to for all this time), but the fact that pinning it makes it jump sides is… an "astonishing" design decision. As I browse I notice a little annoying pop up in the bottom left every time I hover over a link; there is no status bar. I correctly guessed to right click at the top and turn on the status bar (which also got rid of the popup thereafter) and while I am at it, I bring back my favorites bar which was hidden by default (and am pleased to see that all my favorites are still there). The next thing I notice, I like: IE9 is fast. No joke, I visit sites and they seem to be loading visibly much faster – try it! Beyond the speed, I am interested to find out what else is new. I searched and found a few good links: What's new in Internet Explorer 9 Internet Explorer 9 Features (check out the links under "Clean") Top Features If you are a developer, check out IE's msdn home for many articles, e.g. this section on Canvas and SVG. Either way: wherever you are, get IE9 Beta now and judge for yourself. If you don't like it, you can always uninstall (which auto-restores the previous version).

Links to C++ documentation

- by Daniel Moth

After a recent talk I gave on C++ AMP, one attendee was complaining that they were not familiar with lambdas and another found templates hard to parse. In case you are in the same boat, I thought I'd gather some essential reading material for you (also gives me one link to use in the future for referring people to ;-) Lambdas are available (in some shape or form) in all modern languages, so do yourself a favor and learn about them: Lambda Expressions in C++ (and also syntax and examples) Watch Herb Sutter's full length session on lambdas at PDC 2010 Templates, have been around in modern languages for even longer than lambdas (e.g. Generics in .NET), so again go dive in: Templates topic with full table of contents linking to subtopics In fact, why don't you refresh your knowledge and read the entire msdn C++ Language Reference – that's what I am doing! If you are looking to keep up to date with what is happening in the C++ world, stay tuned on the Visual C++ team (aka WinC++ team) blog and ask questions in the C++ forums.

Are you a GPGPU developer? Participate in our UX study

- by Daniel Moth

You know that I work on the parallel debugger in Visual Studio and I've talked about GPGPU before and I have also mentioned UX. Below is a request from my UX colleagues that pulls all of it together. If you write and debug parallel code that uses GPUs for non-graphical, computationally intensive operations keep reading. The Microsoft Visual Studio Parallel Computing team is seeking developers for a 90-minute research study. The study will take place via LiveMeeting or at a usability lab in Redmond, depending on your preference. We will walk you through an example of debugging GPGPU code in Visual Studio with you giving us step-by-step feedback. ("Is this what you would you expect?", "Are we showing you the things that would help you?", "How would you improve this") The walkthrough utilizes a “paper” version of our current design. After the walkthrough, we would then show you some additional design ideas and seek your input on various design tradeoffs. Are you interested or know someone who might be a good fit? Let us know at this address: [email protected]. Those who participate (and those who referred them), will receive a gratuity item from a list of current Microsoft products.

Différence entre :before et ::before, les pseudos-element en CSS3 par Louis Lazaris, traduit par Jérôme Debray

Lorsquevous faites une recherche sur les pseudo-éléments en CSS, vous pouvez constater différentes syntaxes pour :before et :after, précédés de deux-points doublés (::) ou non. Cela peut sembler un peu déroutant de prime abord mais il y a, en fait, une explication plutôt simple. J'avais supposé qu'il y avait une différence de fonctionnement entre les deux types de syntaxe, mais ce n'est pas le cas comme le montre, ci dessous, les explications courte et longue.

Transform 3D vectors between coordinate systems

- by Nir Cig

I've got 6 points in 3D space: A,B,C,D,E,F, that represent 4 vectors. AB is perpendicular to AC and DE is perpendicular to DF. I need to find a transformation matrix M, that transforms AB to DE and AC to DF. In other words: M·AB=DE, M·AC=DF If no scaling was involved, this could be solved with a simple rotation matrix. But since the ratios |AB|/|DE|, |AC|/|DF| might be different, I'm not sure how to proceed.

What changes were made to a document

- by Daniel Moth

Part of my job is writing functional specs. Due to the inevitable iterative and incremental nature of software design/development, these specs need to be updated with additions/deletions/changes over a period of time. When the time comes for a developer to implement features or update their design document (or a tester to test the feature or update their test specs) they need to be doing that against the latest spec. The problem is that if they have reviewed this document already, they need a quick way to find the delta from the last time they reviewed it to see what changes exist and how their existing plans may be affected (instead of having to read the entire document again). Doing that is very easy assuming your Word documents are hosted on SharePoint. 1. Every time you review a document note the SharePoint version and/or date (if it is a printed copy, make sure your printout includes the date in the footer – all my specs do) 2. When you need to see what changed, open the document (make sure you are not using a cached or local offline copy) and on the ribbon go to the "Review" tab and then click on the "Compare" button. 3. Click on the "Specific Version…" option. In the dialog that pops up pick the last version you reviewed and click the "Compare" button. [TIP for authors: before checkin of your document, always compare against the "Last Version" on the SharePoint so you can add appropriate more complete check in comments] 4. What you see now is that in addition to the document you have open, two other documents just opened up. One is in the background (flashing on your task bar) – close that one as it is the old version. 5. The other document is in the foreground and contains all the changes between the old version and the latest one. Be sure not to make edits to this document, use it only for reading the changes. To find all the changes, on the ribbon under the "Review" tab, click on the "Reviewing Pane" to open the reviewing pane on the left. You can now click on each pink change to see what it is. 6. When you are done reviewing changes close the document and don't save any changes (remember if you want to make edits/additions/comments make them in the original document which is still open). And now I have a URL to point to people that keep asking about this – enjoy :-) Comments about this post welcome at the original blog.

Guide.BeginShowMessageBox wrapper

- by Daniel Moth

While coding for Windows Phone 7 using Silverlight, I was really disappointed with the built-in MessageBox class, so I found an alternative. My disappointment was the fact that: Display of the messagebox causes the phone to vibrate (!) Display of the messagebox causes the phone to make an annoying sound. You can only have "ok" and "cancel" buttons (no other button captions). I was using the messagebox something like this: // Produces unwanted sound and vibration. // ...plus no customization of button captions. if (MessageBox.Show("my message", "my caption", MessageBoxButton.OKCancel) == MessageBoxResult.OK) { // Do something Debug.WriteLine("OK"); } …and wanted to make minimal changes throughout my code to change it to this: // no sound or vibration // ...plus bonus of customizing button captions if (MyMessageBox.Show("my message", "my caption", "ok, got it", "that sucks") == MyMessageBoxResult.Button1) { // Do something Debug.WriteLine("OK"); } It turns out there is a much more powerful class in the XNA framework that delivered on my requirements (and offers even more features that I didn't need like choice of sounds and not blocking the caller): Guide.BeginShowMessageBox. You can use it simply by adding an assembly reference to Microsoft.Xna.Framework.GamerServices. I wrote a little wrapper for my needs and you can find it here (ready to enhance with your needs): MyMessageBox.cs.txt. Comments about this post welcome at the original blog.
