  Why Objective-C is Hard

As an active member of "The Internet" and vocal Objective-C coder, I get a lot of questions surrounding the language. They're often framed around thinking about learning the language or trying to write an app, but they also usually involve a phrase like "Objective-C looks really hard" or "what are all those minus signs about?" Both of these are pretty good questions, and I'd like to address why someone might be more hesitant to jump into iOS or OS X development compared to, say, Ruby or J...

  Three things you should never put in your database

As I've said in a few talks, the best way to improve your systems is by first not doing "dumb things". I don't mean you or your development staff is "dumb", it's easy to overlook the implications of these types of decisions and not realize how bad they are for maintainability let alone scaling. As a consultant I see this stuff all of the time and I have yet to ever see it work out well for anyone. Images, files, and binary data Your database supports BLOBs so it must be a good idea to shove ...

  Practice of using spinlock instead of mutex

Spinlock and mutex are two important concepts in multithreading programs. They are used to lock some shared resource to prevent concurrent access which may affect data consistency. But they do have differences, what are the differences? when should we use spinlock instead of mutex? The Theory In theory, when a thread tries to lock a mutex and it does not succeed, because the mutex is already locked, it will go to sleep, immediately allowing another thread to run. It will continue to sleep until...

  A Solution to CPU-intensive Tasks in IO Loops

Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer.  A provocative title to a provocative article.  The only thing it didn’t really provoke in the commentary was much thought ;)  Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or  thread per request; same difference) model as superior.  Yet we all remember where the blocking-IO forking model got Apache in the early days.  ...

  Why is my IP blocked at a website I visit regularly after I changed ISPs?

I just installed a new Express Card with Verizon Broadband wireless last night. Had tons of fun accessing the web from places I usually cannot, (we are in trucking) until I got to my favorite forum. It's a public place I have been to thousands of times, but instead of happily browsing all the daily news events and checking to see if the world blew up yet, I found myself blocked by a big white screen that said YOUR IP ADDRESS HAS BEEN BANNED. What can I do? I can't go to the forum owners to ...
