NTFS compression worth it?
· β˜• 1 min read
Some time ago I researched compression in various systems, ranging from software archivers (like WinRAR, WinZip etc.) to database solutions (like Oracle data compression). Then I figured there is one more type of compression that I did not touch yet - NTFS compression. People on the net say it's pretty much useless, still I decided to give it a try.

Oracle ALTER SEQUENCE - START WITH not working?
· β˜• 1 min read
I googled over many websites explaining the error code and suggesting you do not change it. What if you really need to? One approach is to call NEXTVAL as many times to shift the sequence, so that it starts with your START WITH number (<SW>). A better one is to change INCREMENT BY to a certain value instead, then do NEXTVAL and revert INCREMENT BY.

You happen to own an ATI video card, and updated to Catalyst 10.12. Now most likely you have this weird mouse lag in the top right corner of the screen. Some people report it appearing in other corners as well, both while gaming and staying on Windows desktop.

Intel X25-M 80GB (SSDSA2M080G2GC) - usage report
· β˜• 1 min read
I ordered mine on 12-Apr-2010, and it’s December now, so it’s ~6 months of light use, 135 days = 4.5 months of uptime and an average 6GB of writes per actual day, which translates in just a bit over 1TB of writes. The drive already has 1 bad sector, which was remapped about a month ago. Decided to test performance with AS SSD Benchmark, and here’s the screenshot with results.

If you are like me, and wonder where all the space on C drive went, you might have also stumbled across hiberfil.sys file, which is usually taking a couple of gigs. This is especially important if you are running your system on precious SSD space.

Tortoise SVN - No overlay icons after upgrade
· β˜• 1 min read
Just updated my TortoiseSVN client at home from 1.6.9 to 1.6.11 and found that I can no longer use overlay icons, either in Explorer or in Total Commander (more used to the latter). It appeared as if Tortoise shell extension was not loaded. I tried a restart - same thing.

Exchange - STORE.EXE Eating Too Much Memory?
· β˜• 2 min read
Suppose you are small enough not to want multiple servers each doing exactly one role. If you consider Exchange with the above requirement, you probably have the same problem we used to have. Memory consumption! STORE.EXE takes almost all available memory, no matter how much you allocate to the server. This might not seem like a big problem... until you disable page file, to make sure you server runs on memory, and not on a hard drive.

VB.NET - Different Output in Designer VS Runtime

Let's say you want your custom control display empty string in a certain field, if it has a default value. For example, if your Text field on a custom Label control is identical to its name, show Text field as blank. Would be nice if it worked both ways, i.e. leaving Text field blank would make it identical to the name (or following a certain pattern).

Intel X25-M SSD in HP Proliant DL380 G5
· β˜• 3 min read
Hardware - HP Proliant DL380 G5, two disks, one is Intel SSD and another one is HP SCSI 15K drive, each running as RAID0. Software - IOMeter, latest version. File system - default NTFS partitions were setup, with Intel being a system drive. It might sound like a bit of overhead (bringing incorrect measurements), but honestly, I don't think it would really matter on such speeds and IOps. Controller caching - 25% read/75% write.
