In the times before private repositories were available for free on GitHub.com I had my own git-server installed on a NAS using gitolite. But in a long run I stopped liking managing from console and also I don’t like, when some other corporation looks into my own hidden projects and could be able to cut me off.
As a result I migrated again, this time installing Gitea on a Raspberry Pi following this marvelous guide.
Read more →The process of system upgrade is very easy and was already described here. This is a really great guide. I just want to add few comments, that affected my installation.
The main actions to perform to install latest version of Raspbian are:
Go to raspberrypi.org and check the latest OS codename.
Verify, if this version is not already installed on the Raspberry using cat /etc/os-release command.
$ cat /etc/os-release PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)" NAME="Raspbian GNU/Linux" VERSION_ID="9" VERSION="9 (stretch)" VERSION_CODENAME=stretch ID=raspbian ID_LIKE=debian HOME_URL="http://www.

4k@60Hz is disabled by default on Raspberry Pi 4 (due to a fact of increased memory consumption and device temperature - check docs - that is not needed by most of Pi users).
Read more →I wasn’t even surprised, when I plugged-in an SSD via USB 3.0 into Raspberry Pi 4 and it didn’t work at all. That became a killer for my idea of keeping data outside of the Pi’s microSD card. Observed suspicious symptoms were too obvious:
booting time increased from 20 seconds to 3 minutes LED light of the drive was constantly blinking some commands took extremely long time to execute (sudo blkid, sudo fdisk -l) and even later mounting finished failing or partition formatting hanged indefinitely.
Read more →At first glance, it seemed to me to be a really easy task. Install QEMU for Windows, download latest Raspbian and run! Unfortunately after whole evening of tries I still fail to have it usable anyhow. Maybe it’s not totally not running, but still it’s pretty useless in terms of any further development of application without a device. Simply, at current state (as of 2018-02-18) of QEMU, it doesn’t support emulation of the USB controller, and since the whole network relays on it, there are huge connectivity issues (no network interface at all, so no SSH, no tools installation, no file transfers neither).
Read more →Some time ago I have written a post about, how to setup Windows 10 to wake it up remotely via network using magic packet. The question that remained unanswered is: how to actually send this packet to the PC to trigger it running.
In the first example I will use Raspberry Pi with Rasbpian Stretch Lite installed:
First make sure a tool etherwake is available. If not, this could be fixed with following command, otherwise skip this step:
Read more →Recently I described, how to keep in sync with GitLab latest releases on the Raspberry Pi. And of course it lead me to a problem after unsuccessful update to version 8.17-rc3. This release has the PostgreSQL 9.6.2 embedded and apparently everything got broken in the middle of the upgrade process. After all my tries to revert to previous GitLab version, lots of time wasted (yes, each call to apt-get upgrade or install specified GitLab version was taking several hours!
Read more →I recently noticed that my GitLab installed on Raspberry Pi (running Jessy) stopped updating and stick to version 8.7.9, however the latest one as of today is 8.16.4.
Normally apt-get updateand apt-get upgradeshould do the trick. But it turned out there was a change in the build system and newer packages don’t get uploaded into ‘raspbian’ version of repository. For details - take a look on issue #1303. Although quick patch is following and short:
Read more →Yet another day I tried to play a video from an SMB share using OSMC. Must say so – this player is just amazing and works great on Raspberry Pi 2 (although on Pi 1 whole stack was far too slow for HD content). So what could go wrong here?
I am a bit paranoid about sharing and access rights. That’s why I setup that share with a dedicated user on a server and guarded with a strong password.
Read more →Few days ago I ordered Raspberry Pi 2 and unboxed it just today. After a lecture of few videos on Channel9 about Microsoft //Build/ 2015 I was very excited and wanted to test the latest Windows 10 for IoT myself. Then I simply hit obstacle after obstacle and wasted more than 10 hours of my life to simply get the image written on microSD card. That was a real nightmare, but maybe because I am not a typical Windows user.
