Interesting database features

Besides other things this weekend I have written this little article comparing some of the most famous databases these days, MySQL, PostgreSQL and Oracle.

I haven’t done too much research because somebody did the job before, I just took what I found more interesting for people who could be thinking on switching from Oracle.

If anybody finds any wrong information given by my document let me know please, I’ll fix them ASAP.

Linked on openwrt.org

Yeah! check it out! on their Recent Links section! I’ve noticed it because looking on apache logs when I saw some IP addresses trying to access to a wrong folder with referer openwrt.org. They were looking for wordpress default folder where I had it before the official announcement so I’ve added an alias to my apache configuration to keep those links working.

Take a look on my wireless section.

linux-2.6.13 working with ipw2200 and WPA

After some time working on this I finally found some posts Google’ing a little that take me to right answer. Because 2.6.13 and above kernels have a new version of linux wireless extensions you can’t use the ipw driver when calling to wpa_supplicant instead wext driver must be used.

So…get your kernel compiled with wireless support, install ieee80211 which will tell you to remove /usr/src/linux/include/net/ieee80211.h, just do as you want I moved it to my home and the package compiled without problems. Then install ipw2200 and modify your /etc/conf.d/net to include the following:

wpa_supplicant_ifNN=”-Dwext”

Reboot to load new kernel and modules, and let me know!

The PHP photo album

This is the reason why I’m asleep today…:P, LinPHA. Lastly I was thinking on updating my flickr account from free to pro cause I needed a place to store all my current pictures and all I will take on my next holidays.

I started last Monday looking for something interesting on this topic at freshmeat, after little surfing I set up yappa-ng which is quite good, but it has an old look-a-like which does not convinced me so I kept surfing till I got to LinPHA, it looks cool! it brings ease of use, nice management interface, users management, groups management, categories, comments, SPAM blocker (for comments but I guess it’s not too much reliable…), etc.

Take a look! and let some comments if you like it :^D.

Using dm-crypt in Gentoo

After long time using cgd I missed its functionality and EncFS was not what I wanted to keep my laptop’s home safe, finally I’m using dm-crypt which is kernel-side managed.

I’ve found a really nice guide which I strongly recommend to read before start to do anything. I’m going to post some directions to make it ready at boot stage.

First of all sys-fs/cryptsetup has to be installed, remember kernel support is needed too (see the guide), Gentoo’s boot sequences allows you to have the kernel drivers as modules because they are loaded before mount is called. In Cryptographic Options at least AES is needed cause it’s the default.

Once you have kernel and userland ready, let’s configure some files:

When creating the volume using cryptsetup command a passphrase will be asked, it is important to keep this in mind cause it will be used to mount your partition when booting.

HP-UX daily checks

Before I started to get involved into the management of HP-UX servers at work, someone had to log in and check the system status (cpu, disk activity and so on…). I got bored quickly to do so every morning so finally I decided to do a little script which sends a report every morning scheduled in cron.

I have uploaded the script to my server hopping it could be useful to someone else who have to deal with this OS and maybe some comments about how to improve it will be welcome .
