Už je to v poslední době poněkolikáté co jsem nalezl BrmLab s dveřmi dokořán a ve vnitř nikdo. Dnes jsem dokonce čekal cca 15 minut na hříšníka který se neobjevil ale věci měl ve vnitř. Přikládám fotku osobních věcí hříšníka. Bylo to chvilku před 14. Ku....va už. Tohle nejde.... TomSuch

31 Mar '17

Ahojte Mozna uz jste zachytili v automaticky generovanem reportu o udalostech v nejblizsim tydnu, chci zkusit nastartovat tradici nepravidelne poradanych hackerskych Capture The Flag udalosti, ktere maji v hackerske komunite dlouholetou tradici a jsou obvykle poradane prilezitostne jako doprovodny program k ruznym konferencim apod. Podrobny popis o co jde sem nebudu duplikovat, je na wiki https://brmlab.cz/event/ctf Jak zminuju na wiki strance narocnost bude stredni. Zacinat s necim lehcim by byla nuda pro vsechny. Zkusenejsi by to nebavilo a mene zkuseni by se nic nenaucili. Od navstevniku se po zakladnim vysvetleni predpoklada aktivni zapojeni se, ale tim se nenechte odradit od pripadne navstevy. Prave ti mene zkuseni z vas, kteri by si treba netroufali se neceho takoveho zucastnit sami za sebe, se mohou leccemu priucit, kdyz uvidi jak se to dela prakticky, at uz nosite klobouk libovolne barvy :) Pozn: Stream ani zaznam z akce nebude. nashle ve ctvrtek vecer od 19h ruza -- e-mail: ruza(a)ruza.eu www: http://ruza.eu http://brmlab.cz Chcete mi udelat radost a sebe ochranit pred zvedavyma ocima Velkeho bratra?

by Daniel Handl 30 Mar '17

30 Mar '17

Ahoj, hledáme testery sw, tak jsem si říkal, že by se tu možná někdo našel :) Požadavky: - pečlivost - obecná orientace v IT - když bude umět webový technologie - HTML, JS, CSS, ... bude to jen dobře Makat může, kde uzná za vhodné nebo u nás v kanclu v Praze 9. Odměnu a způsob spolupráce bychom probrali osobně. Díky moc. Ať se daří! Daniel Handl *jednatel* +420 604 209 876 TOVARNA.CZ <http://tovarna.cz/>

vyhazování hadic - probírka do 2017-04-20
by Pinky 29 Mar '17

29 Mar '17

Ahoj, pokračuji postupně s úklidem chemlabu, po pláštích přišli na řadu hadice. V biolabu na zemi jsem vytřídil řadu hadic které jsou kandidáty na vyhození. Hadice které přijdou zachovat vysí na chemlabích dveřích. Pokud někdo něco máte proti, dejte konkrétní kusy stranou (ne na dveře!) a napište mi. Dne 2017-04-20 budou nevytřízené hadice zlikvidovány. Pinky.

Raspberry pi kernel cross-compiling
by Robert Holub 22 Mar '17

22 Mar '17

Ahoj pratele, pred casem jsem se bavil o moznosti prekladat jadro pro rpi na rychlem PC. Navod byl udajne priserny. Zkousel jsem to a opravdu, navod nic moc, je tezke se v nem vysnat. Nicmene nakonec jsem uspel s kompilaci a instralaci jadra vcetne modulu. Problem: Navod obsahuje chyby v prikazech (nekolikrat chybi '/') a popis nastaveni cest pro tools a volba 64bit/32bit je take matouci. Zde je navod ktery by mel byt jiz jasnejsi, mam to vystavit do knowledge base? Mr.holub === Cross-compiling === == Install toolchain Use the following command to install the toolchain: git clone https://github.com/raspberrypi/tools You can then copy the tools directory to a common location (I've put it in /var/lib/gitolite/rpi but you can use any other dir.) add tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin to your $PATH For 32-bit host systems: use tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin For 64-bit host systems: use tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin Example of adding path to the existing paths for particular shell session (your subdir will be probably different: 32bit host example: PATH=$PATH:/var/lib/gitolite/rpi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin 64bit host example: PATH=$PATH:/var/lib/gitolite/rpi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/ == Get sources To get the sources, refer to the original GitHub repository for the various branches. git clone --depth=1 https://github.com/raspberrypi/linux == Build sources Enter the following commands to build the sources and Device Tree files: For Pi 1 or Compute Module or Pi ZERO: cd linux KERNEL=kernel make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcmrpi_defconfig For Pi 2/3: cd linux KERNEL=kernel7 make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- bcm2709_defconfig Then, for both (replace X by number of threads - often 1.5 * number of cores): make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage modules dtbs -j X Install directly onto the SD card Having built the kernel, you need to copy it onto your Raspberry Pi and install the modules; this is best done directly using an SD card reader. First, use lsblk before and after plugging in your SD card to identify it. You should end up with something like this: sdb sdb1 sdb2 with sdb1 being the FAT (boot) partition, and sdb2 being the ext4 filesystem (root) partition. If it's a NOOBS card, you should see something like this: sdb sdb1 sdb2 sdb5 sdb6 sdb7 with sdb6 being the FAT (boot) partition, and sdb7 being the ext4 filesystem (root) partition. Mount these first, adjusting the partition numbers for NOOBS cards: mkdir /mnt/fat32 mkdir /mnt/ext4 sudo mount /dev/sdb1 /mnt/fat32 sudo mount /dev/sdb2 /mnt/ext4 Next, install the modules: sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- INSTALL_MOD_PATH=/mnt/ext4 modules_install Finally, copy the kernel and Device Tree blobs onto the SD card, making sure to back up your old kernel: cp mnt/fat32/$KERNEL.img /mnt/fat32/$KERNEL-backup.img scripts/mkknlimg arch/arm/boot/zImage /mnt/fat32/$KERNEL.img cp arch/arm/boot/dts/*.dtb /mnt/fat32/ cp arch/arm/boot/dts/overlays/*.dtb* /mnt/fat32/overlays/ cp arch/arm/boot/dts/overlays/README /mnt/fat32/overlays/ umount /mnt/fat32 umount /mnt/ext4 Another option is to copy the kernel into the same place, but with a different filename - for instance, kernel-myconfig.img - rather than overwriting the kernel.img file. You can then edit the config.txt file to select the kernel that the Pi will boot into: kernel=kernel-myconfig.img This has the advantage of keeping your kernel separate from the kernel image managed by the system and any automatic update tools, and allowing you to easily revert to a stock kernel in the event that your kernel cannot boot. Finally, plug the card into the Pi and boot it!
