Linux thoughts from a linux Geek (aka GEEX)

While tuning and benchmarking an HP backup device (HPD2D backup system) I need to estimate the average file size of the IMAP server storage. You may think I could just count the number of files and the divide the used space by the number of files, but that wasn’t the case because i don’t want all the files to count, in this case I just need the maildir files that have the email content.

About a year ago I’ve setup some linux RHEL 6 with multipath access to an HP EVA storage. Today I needed to do it again, and to do so i needed to list all the path available to the storage device, here’s my command line (hope it helps someone else) to list all the path and volumes:

Hi, Recently I installed a tor relay server but I couldn’t find the rpm for Scientific Linux, so i decided to get the source code and copile it myself, even better i decided to make the RPM. I’m really short on time so I didn’t create a repo for it (if someone out there vulunters to help maintaining the repo I’ll do it) For now here’s the rpm, enjoy. Pedro M. S. Oliveira   Tor RPM for REHL6, CentOS 6, Scientific Linux 6 (137)   PS – For those of you that doesn’t know what tor project is you may check https://www.torproject.org/

Just a link about something I found interesting, its about using BRTFS on OpenSuSE. http://news.opensuse.org/2012/01/23/using-btrfs-on-opensuse-12-1/ Cheers, Pedro

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?
