    Starting to Learn Coding

    Oh, I do Fourier transforms, linear algebra, permutations, etc. all the time, just no calculus.

    Starting to Learn Coding

    Schools tend to give a lot of room to calculus, but in the past ten years or so as a developer (mainly in industrial automation and measurement) I've never had much use for it, and I can't say I know very many other programmers who have.

    .Net, MySQL and character sets...

    I'm trying to get a C#/.Net page to work with MySQL (through MySQL Connector/Net), but I'm having some problems with special characters. In the MySQL command prompt, everything displays OK, and all character set variables are set to latin1 and Swedish collation, except system, which is UTF8, but...

    IE9, HTML5, IIS7 and Mime types

    Solved it. Web.config to serve the correct MIME type: <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <staticContent> <remove fileExtension=".mp4" /> <mimeMap fileExtension=".webm" mimeType="video/webm" /> <mimeMap...

    IE9, HTML5, IIS7 and Mime types

    Hi! I'm trying to make a web page with HTML5 video content. It looks good in every browser except IE9, which doesn't show the video. Looking under Developer Tools->Network, it displays the mp4 file as type "text/html". This is what i have in my web.config: <?xml version="1.0"...

    (C++) - Any faster way to keep a float between zero and one ?

    Thanks, I'd forgotten about that. Assembler comes up so rarely that I never really learned it properly.

    (C++) - Any faster way to keep a float between zero and one ?

    Do'h! Too slow. Use Mike's code, his SSE will be a lot faster than my poor x87.

    (C++) - Any faster way to keep a float between zero and one ?

    Actually there is. The i don't have your exact code but the below should give you an idea. From this: bool v5(float* p, unsigned char* s, int isize) { for(int i = 0; i < isize; i++) { short sa = p[i]*255; s[i] = sa & 0x8000 ? 0 : (sa & 0x7F00 ? 255 : sa); } } To...

    (C++) - Any faster way to keep a float between zero and one ?

    That's a bit odd. The cast from short to char should be cheap enough (a single AND while all variables are in registers). Possibly you're confusing the OOO reorderer and saturating the FPU with the FMUL's so close together and it works better with some integer code between (although three FMUL's...

    (C++) - Any faster way to keep a float between zero and one ?

    I just looked at it very briefly, and it may be compiler dependent, but i found the below method about 2.5 times faster than what you posted. short a = color.r*255; final_unsigned_char = a & 0x8000 ? 0 : (a & 0x7F00 ? 255 : a);

    Noobie: Help with Javascript

    The .js and .css files are not on the server, at least not where you link to them. Go to your site. In Firefox, view source, click the .js file, and you're greeted with a 404.

    Microsoft Visual Studio 2010 is now available

    VS has has this feature for a long time. I just checked my 2005, and its there. As far as I can recall it's been there since VS6.

    Height problem with floating DIV's

    Thanks, that's really useful. Now I just have to dig up an old XP box to try it on (doesn't work on Vista/7), but I should have a couple laying around.

    Height problem with floating DIV's

    Actually, the design SoRnMaN linked won't expand to the bottom of the page (go to the page, copy the exact source, paste in a local html file and remove content from the columns so that each column is shorter than the page to see for yourself). I added two position:absolute (left:0px and right...

    Height problem with floating DIV's

    Thanks, that's nearly what I want, but I also need the columns to stretch to the bottom of the page if the content of all columns are shorter than the browser window, and I can't seem to get it right.
