davidddavidson··on Pullup, the site you join via pull request
Presumably you need to make some other code change/improvement as well with the pull request or else it will be rejected.
davidddavidson··on Show HN: Codewars
The difference is that Google had a clear unique value proposition that was to provide search results (and only search results) back extremely quickly and were highly relevant when they other players were focused on creating "web portals" and did not focus attention on search.

With CodeCombat and Codeacademy there UVP is very obvious (make learning to code a game and teach to code online resp.) and had not previously been done. With this site I don't understand what the UVP is (social programming challenges?) that hasn't been already by something like TopCoder, Sphere Online Judge, etc.

davidddavidson··on Show HN: Codewars
The name is pretty similar to CodeCombat (http://www.codecombat.com) and I'm not clear on how this site is better than Codeacademy (http://www.codecademy.com/). There are already a bunch of programming koans/katas available on the internet.
davidddavidson··on Student Startup Plan
It's not a new thing. It's just a different marketing strategy for income based repayment.

davidddavidson··on Ask HN: Do you run a SAAS app?
The site template is a very bland and looks just like out-of-the-box bootstrap. Also you have a typo above the signup box:

> Sign up for a free trail

should say "trial" instead of "trail"

> - You believe the actor-model concurrency is a better idea.

Better than using stateful concurrency? If you have read "Concepts, Techniques, and Models of Computer Programming" you would see that each approach is not necessarily "better", they each have their own unique advantages and disadvantages

To quote from CTM: The message-passing approach is often the best for multi-agent programs, i.e., programs that consist of autonomous entities (“agents”) that communicate with each other. The shared-state approach is often the best for data-centered programs, i.e., programs that consist of a large repository of data (“database”) that is accessed and updated concurrently. Both approaches can be used together for different parts of the same application.

davidddavidson··on Please, Stop Helping the Hackers Guess My Passwords
Why wouldn't they just store the date of when you last changed your password?
davidddavidson··on When does learning (to code) stop being so hard?
You should fix the links on your blog. All of them except for the HN discussion link have tommy.authpad.com prepended to them.
davidddavidson··on Always “hover” before you click? Wrong.
Hovering is showing 'www.google.com' for me in Chrome 22.0.1229.94 so I'm guessing the comment is incorrect (or only correct for some unknown version of Chrome). I don't have a mac so I can't test Safari.
davidddavidson··on Always “hover” before you click? Wrong.
Click that link to /utils/onclick.html and then try clicking the link on the new page that says it will go to www.google.com
davidddavidson··on A Crash Course in Computer Science: Reading List
Here is the blog post that goes along with this - http://jchenry.me/2011/05/26/Reading-List-%3AA-Crash-Course-...
davidddavidson··on A Crash Course in Computer Science: Reading List
I would add the book 'Elements of Computing Systems' [1] by Nisan and Schocken (in addition to CS:APP) as a replacement for COD. COD is more of a reference book rather than a teaching one.

From the last two lines of test it's returning 0, but the function that calls it (ThreadProc_dbg) declares a local variable result and sets it to 1, then calls test but doesn't store the return value into result so the result != 1 check is always false and the program will always display "your CPU isn't buggy!"

davidddavidson··on Scott Hanselman's 2011 Ultimate Developer and Power Users Tool List for Windows
No, it's under 'Things Windows Forgot':

"VoidTools Everything Search Engine - Sometimes you just want a text box, a 300k application and you want to Search Everything. This tiny utility makes it super easy to search your entire hard drive (all of them actually) instantly. You can Google the whole internet with Bing in a second, why shouldn't you be able to do the same with your hard drive. Best part is that it works on any version of Windows, even Windows 2000."
