• "PHP: Good Parts"-ish book / reference

  - by julkiewicz

  Before I had my first proper contact with Javascript I read an excellent book "Javascript: The Good Parts" by Douglas Crockford. I was hoping for something similar in case of PHP. My first thought was this book: "PHP: The Good Parts" from O'Reilly However after I read the reviews it seems it totally misses the point. I am looking for a resource that would: concentrate on known shortcommings of PHP, give concrete examples, be as exhaustive as possible I already see that things can go wrong. If you want to close this question: Please consider this, I looked through SO, and Programmers for materials. I obviously found this question: http://stackoverflow.com/questions/90924/what-is-the-best-php-programming-book It's general, mine is specific. Moreover I'm reading the top recommendation "PHP Objects, Patterns, and Practice" right now. I find it insufficient -- it doesn't address the bad practices as much as I would like it to. tl;dr My question is NOT a general PHP book request.

• CSS vendor prefixes redux

  Well, reactions to my proposal toabolish vendor prefixes are mixed, and I might have overshot my target here.Eric Meyer,Jonathan Snook, andStephen Hay reacted to my post,and it’s clear that they believe vendor prefixes ought to continue to exist. Manycommenters said the same thing, although some other commenters agreed with me.Daniel Glazman, W3C CSS co-chair, reactedin a similar vein, and agreed that there is something wrong with the current vendor prefiximplementation. He even welcomed the discussion....Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Conscience and unconscience from an AI/Robotics POV

  - by Tim Huffam

  Just pondering the workings of the human mind - from an AI/robotics point of view (either of which I know little about)..   If conscience is when you're thinking about it (processing it in realtime)... and unconscience is when you're not thinking about it (eg it's autonomous behaviour)..  would it be fair to say then, that:   - conscience is software   - unconscience is hardware   Considering that human learning is attributed to the number of neural connections made - and repetition is the key - the more the connections, the better one understands the subject - until it becomes a 'known'.   Therefore could this be likened to forming hard connections?  Eg maybe learning would progress from an MCU to FPGA's - therefore offloading realtime process to the hardware (FPGA or some such device)? t

• Session and Cache are By Reference

  Recently a colleague remarked that if he got a List of some type out of the ASP.NET Cache, and changed an item, the Cache item would also change.That is correct. Session (InProc) , Cache and Application all return "live" references. A good writeup on this can be found by friend and fellow MVP Rick Strahl here:http://www.west-wind.com/Weblog/posts/1214.aspxIf you do not want this behavior, you need to either delete the Session / Cache / Application object and replace it with what you want later, or...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Ubuntu on Thinkpad Edge 11/13/14/15

  - by lasseespeholt

  I think a community wiki on problems (and solutions) when installing Ubuntu (10.10) on a Thinkpad Edge 11 would be nice (because I just got one ;)). I'll contribute with my own problems and solutions, and hope others will join too. Thinkwiki entry for the Edge 11 Known problems: No wifi-driver, solution: answer #1, answer #2 Fan is loud, even though it's on auto. No solution. Thinkfan is a possible solution, but correction values for sensors should be supplied (mapping sensors to specific areas). Also, one sensor is between -100C and +100C - maybe some kind of deactivation would help. FN keys stop working: see below. No sound on headphones: see below.

• Is there a good way to get pixel-perfect collision detection in XNA?

  - by ashes999

  Is there a well-known way (or perhaps reusable bit of code) for pixel-perfect collision detection in XNA? I assume this would also use polygons (boxes/triangles/circles) for a first-pass, quick-test for collisions, and if that test indicated a collision, it would then search for a per-pixel collision. This can be complicated, because we have to account for scale, rotation, and transparency. WARNING: If you're using the sample code from the link from the answer below, be aware that the scaling of the matrix is commented out for good reason. You don't need to uncomment it out to get scaling to work.

• What triggered the popularity of lambda functions in modern programming languages?

  - by Giorgio

  In the last few years anonymous functions (AKA lambda functions) have become a very popular language construct and almost every major / mainstream programming language has introduced them or is planned to introduce them in an upcoming revision of the standard. Yet, anonymous functions are a very old and very well-known concept in Mathematics and Computer Science (invented by the mathematician Alonzo Church around 1936, and used by the Lisp programming language since 1958, see e.g. here). So why didn't today's mainstream programming languages (many of which originated 15 to 20 years ago) support lambda functions from the very beginning and only introduced them later? And what triggered the massive adoption of anonymous functions in the last few years? Is there some specific event, new requirement or programming technique that started this phenomenon?

• Web application deployment and Dependencies

  - by Reith

  I have a free software web application that using other free software scripts for appearance. I have trouble to decide whether should I copy source code of used scripts to my project main repository or list them as dependencies and ask user to install them himself? Since some of scripts solving browser compatibilities issues and I'm not a good web designer (i hate to check my web site on IE to see compatibility) using the newest version of scripts is preferable and second solution works here. But it has problem with scripts aren't backward-compatible with versions I've used them for development. Maybe another method is well-known for this issues that I don't know them.

• Physics-based dynamic audio generation in games

  - by alexc

  I wonder if it is possible to generate audio dynamically without any (!) audio assets, using pure mathematics/physics and some input values like material properties and spatial distribution of content in scene space. What I have in mind is something like a scene, with concrete floor, wooden table and glass on it. Now let's assume force pushes the glass towards the edge of table and then the glass falls onto the floor and shatters. The near-realistic glass destruction itself would be possible using voxels and good physics engine, but what about the sound the glass makes while shattering? I believe there is a way to generate that sound, because physics of sound is fairly known these days, but how computationaly costy that would be? Consumer hardware or supercomputers? Do any of you know some good resources/videos of such an experiment?

  Transparent Data Encryption is designed to protect data by encrypting the physical files of the database, rather than the data itself. Its main purpose is to prevent unauthorized access to the data by restoring the files to another server. With Transparent Data Encryption in place, this requires the original encryption certificate and master key. It was introduced in the Enterprise edition of SQL Server 2008.

• How to choose a new technology for mastering and not lose sense of reality and practicality?

  - by Eyewan

  How to choose the right next step in learning programming and mastering new technologies? I have experience with WinForms applications in C# .NET. Next what I see as a good area of expanding the knowledge is ASP.NET. Language I already know, C #, so I think there is now more a matter of mastering new technologies. Also I have interest in WPF. Perhaps the best is to work on ASP.NET and WPF at the same time. Sometimes the problem is when we do not have motivation, but also known to become a problem when we want to much :) How to choose a new technology for mastering and not lose sense of reality and practicality?
