Zend CE has a Worm
+0 Vote Up -1Vote Down

After updating the AVGFree virus definitions, I was surprised to find that Zend CE (Community Edition) 4.0.6 had a worm in the JavaServer.exe file. There was greater surprise when Zend CE 5.3.9 (5.6.0-SP1) also had the same worm.

This is the message identifying the worm (click on it to see a full size image), and you can read about this particular worm on the Mcafee site:

Unless you have the full version of AVG or …

Aligning IO on a hard disk RAID – the Theory
+4 Vote Up -0Vote Down

Now that flash storage is becoming more popular, IO alignment question keeps popping up more often than it used to when all we had were rotating hard disk drives. I think the reason is very simple – when systems only had one bearing hard disk drive (HDD) as in RAID1 or one disk drive at all, you couldn’t really have misaligned IO because HDDs operate in 512-byte sectors and that’s also the smallest amount of disk IO that systems can do. NAND flash on the other hand can have a page size of 512-bytes, 2kbytes or 4kbytes (and often you don’t know what size it is really) so the IO alignment question becomes more relevant.

It …

Caching could be the last thing you want to do
+6 Vote Up -0Vote Down

I recently had a run-in with a very popular PHP ecommerce package which makes me want to voice a recurring mistake I see in how many web applications are architected.

What is that mistake?

The ecommerce package I was working with depended on caching.  Out of the box it couldn't serve 10 pages/second unless I enabled some features which were designed to be "optional" (but clearly they weren't).

I think with great tools like memcached it is easy to get carried away and use it as the mallet for every performance problem, but in many cases it should not be your first choice.  Here is …
