Few months ago I had to run a test to see if DNA sequence files (FASTA files) compress better than simple text files. DNA files contains only 4 characters (A, C, G, T) so you will expect that they will compress really well compared with text files. However, the DNA code is pretty random (well […]

How we spend Moor dividend During the last 28 years, the clock speed increased 586 times. The Intel Pentium processor, introduced in 1995, achieved a SPECint95 benchmark score of 2.9, while the Intel Core 2 Duo achieved a SPECint2000 benchmark score of 3108.0, a 375 times increase in performance in 11 years.

Some raw notes about distributed databases. If you want to start with parallel databases then you need some good knowledge about traditional (non-distributed) data bases.

Web applications are increasingly popular, but are they truly “real” applications? Given the limitations of web technology, it’s clear that web “applications” can’t match the functionality of traditional desktop applications. This is why 96.4% of users still prefer desktop software (like Word) over basic online tools (such as Google Docs). An interesting observation about the

Here is a very intresting test that shows that DD3 is only few percent faster that DD2 even if it is way way way more expensige: http://www.tomshardware.com/reviews/ram-speed-tests,1807.html “You get the best bang for the buck if you stick to the mainstream of the memory market, which currently is still DDR2-800 or 1066, preferably at low

Here is a “nasty” article about how to hack your Windows 7 32 bit to use more than 4GB or RAM. It looks like MS Windows can use more than 4GB or RAM but MS don’t want to sell it that way: “That 32-bit editions of Windows Vista are limited to 4GB is not because

I strongly recommend against Windows XP on 64 bits. It has NO advantage over Win XP 32 bit unless you have more than 3.2GB of RAM.If you have 4GB of RAM, Win XP 64 bits will give you back those 0.8GB of RAM that Win XP 32 bit cannot access, but at the same time

There’s nothing worse than a Delphi programmer writing code like a Visual C++ programmer. Delphi developers have the distinct advantage of creating applications that are isolated within the Windows OS. This is why applications compiled for Windows 3.1 are still running on Windows 7. However, Borland didn’t cover every area—especially when it comes to non-isolated
