Po úspešnom absolvovaní letného kurzu prežitia a absolútnej spokojnosti s výcvikom, som dnes ráno chcel pozrieť aký ďalší kurz absolvovať u Patrika a jeho teamu. Hlavná stránka www.armytraining.sk sa mi zdala byť ako keby zmenená oproti tomu, kedy som ju naposledy navštívil. Scrollol som dole a bol tam formulár, korý som ešte nevidel, tak som sa začítal, čo to je. Foto návod prihlásenie

Vladov blog už sledujem pár rokov a absolvoval som s ním osobnú konzultáciu tovaroznalectvo v Terne, Aupark, Bratislava. Veľa informácií má na blogu, čo je veľmi dobré a ďakujem za ne. Infá na blogu sú jedna super vec, ale osobné stretnutie má predsa len pridanú hodnotu a z druhého uhľa pohľadu, ak naďalej chcem čítať jeho bádania a výskumy, tak ho predsa finančne musím podporiť.

Mojou srdcovkou vždy boli a sú ThinkPad notebooky. Preto koncom roku 2013 som už ďalej nečakal a z eshopu lacne-pc.sk za 200 Eur kúpil svoj prvý repasovaný notebook, T60-ku ešte z dielne IBM a nie Lenovo. Dovtedy som nemal skúsenosť s repasovanou technikou, ale v eshope uvádzali 2-ročnú záruku, tak som neváhal. Netušil som v akom stave bude, predsa je to použitý notebook a hlavne

Today I finally made time to try Pi's composite TV out [AV button on TV remote control :]. I had to edit my NOOBS /boot/config.txt to disable HDMI and enable Standard Definition Video. # for more options see http://elinux.org/RPi_config.txt # uncomment if you get no picture on HDMI for a default "safe" mode #hdmi_safe=1 # uncomment to force a console size.

With Console.app I had the problem that when I switched to output /var/log/apache2/error_log I didn't see /var/log/system.log and yesterday I read http://kkovacs.eu/cool-but-obscure-unix-tools and found multitail so I played with it.

Today I used Google's public DNS servers with a WiFi hotspot, never used it so I read about it and came acrooss https://code.google.com/p/namebench/ I tried it with the ISPs DNS servers and got the following result (suggestions for improving) http://namebench.appspot.com/id/71560011 for 100 queries and http://namebench.appspot.com/id/73540001 for 200 queries.

I tried to install Kali in VBox with 4GB and for the second time on 8GB which wasn't enough, according to /var/log/syslog So I checked the install docs and there was the answer how much should I use. So it's good to go throught the install docs before installing at http://docs.kali.org/installation/kali-linux-hard-disk-install and check the requirements. After installing the system takes 9.7GB

I just came across of Filesystem Hierarchy Standard (FHS). It is a standard that consists of a set of requirements and guidelines for file and directory placement under UNIX-like operating systems. The guidelines are intended to support interoperability of applications, system administration tools, development tools, and scripts as well as greater uniformity of documentation for these systems.

It's nice that MySQL has the replace query so instead SELECTing to check if the data exists in the DB and than INSERTing or UPDATEing I just need to write one query. So instead this: $q = "SELECT id FROM table WHERE name = 'value' AND name2 = 'value2' LIMIT 1;"; $id = $database->get_one($q); if ($id > 0) { $q = "UPDATE table SET name = 'value', name2 = 'value2' WHERE id = $id LIMIT 1;"; }

Yesterday I watched again Antitrust, but now in HD 720p to better see the commands he used :) He was playing with inodes to restore removed data and I became curious, because I heard and saw inodes, but never knew what are they. For me useful info was at http://www.linfo.org/inode.html and http://www.cyberciti.biz/tips/understanding-unixlinux-filesystem-inodes.html I didn't know about the command

Here are some thoughts about cleaning up data after a backup, recovery or restoration. Rsync stats from one USB harddrive to another, it took over 17 hours during which I was away from home :) My bigger problem was that I needed to manualy scan the images, due some partition recovery incident. The directory contained 103541 JPGs that was 12 GB of data. For moving just the wider photos (

Some of my best practites for PHP 1. Check the syntax of all of the php files: localhost:~ $ find $(pwd) -name \*.php -exec php -l '{}' \; 2. Set php.ini for development: error_reporting=8192 display_errors=On display_startup_errors=On log_errors=On error_log=error_log report_memleaks=On expose_php=On asp_tags=Off 3. Watch out for proper type handling: $clean_int = (int)$dangerous_int; 4
