Linux thoughts from a linux Geek (aka GEEX)

MENTAL NOTE – Setup bridge device on centos, rhel, scientific linux

MENTAL NOTE from http://moze.koze.net/?p=81 Converting SSL-certificates from CRT format to PEM Dovecot, for example, seems to expect pem-files, while RapidSSL only issues crt-files. The solution? Use OpenSSL to convert (via the DER-format) to pem: openssl x509 -in input.crt -out input.der -outform DER then openssl x509 -in input.der -inform DER -out output.pem -outform PEM

There is a functionality that is also a very big security flaw – FACE RECOGNITION. Google warns you about face recognition not being the safest of methods to unlock your phone, but nevertheless you can pass the locking feature just by using any other photo of you.

Hello,

Recently I’ve updated my openSuSE 11.4 to the latest openSuSE 12.1, it was a hassle free upgrade and my system is running smoothly, nevertheless I didn’t use one of my favorite features on this laptop, the built in GSM card. Today I needed it and, bummer, it didn’t work, even if I could see it in network manager…

It’s been a while since I’ve written anything about my RC car, I won’t be writing a lot but I’ll leave you guys some photos of my last ride on the local track.

I had a really nice afternoon riding one of my favourite toys, I ran it really hard (lost some of the love i held to my car) and i didn’t manage to break anything :) I’m getting better or all the upgraded parts really worked out :)

I’ve bought it 2 months ago (more or less) and it’s been my companion since, it’s my favorite gadget and the one i use more when I’m not working. So… why do i like it this much, what is it’s strengths and weakness?

Hi today I was using my new laptop (well it has about 1 month now) and I thought in sharing my usage experience with it. My Vaio is a VPCSB and I run it with OpenSuSE 11.4 X86_64. I have a thing for Sony Vaios, this one is my 4th. I like Vaios for their build quality, looks, performance and size as I also travel quite a bit.

Hi, this is more a mental note for myself but it can be useful to someone. Here’s how to transform a Unix timestamp to human readable date using bash date -d @1000000042 Sun Sep 9 02:47:22 WEST 2001 Cheers, Pedro Oliveira

Now the fun part, being a bit drunk i did something like (i didn’t want to do it jut typed ENTER before the rest(someway i mistaken TAB with ENTER)): sudo chown -R pedro:pedro / I thought to myself… this is taking ages let me have another drink… and then i woke up but it was too late, I’m running to the lap but I have ext4 and an SSD so my entire file system had my UID and GID.

I have backups of everything I do, even the complete FS but the backups are 8000 Miles away and in Angola the best i can get in Internet access is 2Mb. I felt a bit desperate, I say a bit so I don’t tell you I would like to drink a bottle of vodka to forget the stupidity I made…

Today Oracle launched a paper that focus the gains of Oracle solutions over Solaris VS IBM solutions over AIX.

You can find the paper here.

After reading the entire paper I find it quite tendentious.

I’m not a Oracle/SPARC fan nor a IBM/Aix fan, although I’ve worked with both for years, my favorite OS is Linux, and well i also Solaris a bit. So why do I find it tendentious:

1 – The way it’s written, for every user comment they say a slightly positive thing about IBM, but the really good thing is Oracle/Solaris.

2 – I don’t doubt that the interviews were conducted I’m almost sure the people were selected. As I told before I like Linux, if i want i can manage to get 20 sys admins that will focus that Linux is better than Solaris, I just have to select the right ones. Although I know it’s not the case in many issues, it is others. Everyone likes to defend it’s favorite technology.
