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.

But one thing that drove me crazy was the need of having Live Writer aka Open Live Writer installed to write a simplest post. 5 years ago this tool looked amazing. Although time has passed quickly, and meanwhile OLW seemed to be also abandoned by Microsoft.
Read more →I am a really trouble guy and having problems and spending sleepless nights seems quite often to me. But gee, it’s 2019! and still it’s not very obvious, why sometimes it’s so hard to do things that in theory should be so easy.
You probably noticed, that I like TeamCity. Since I am going to participate in JetBrain’s latest TeamCity Plugin Contest 2019 I came up with idea of setting up virtual machine with a test instance of the CI, instead of messing up my production one to only test the plugin.
Read more →During installation of Android Studio we usually end-up with Android Emulator using Intel HAXM. This is still pretty good virtualization platform. Unfortunately might lead to a clash, since only one virtualization technology could be used at a time. And if you continue using Docker for Windows or any other Hyper-V based virtual machine with Linux system, something will not work (depending, what was launched first).
Fortunately Microsoft solved this problem with 1803 release for Windows 10.
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:

Funny thing, really, since as a user I was supposed to enter Settings, navigate to Mobile Hotspot, define password and swipe to enable it. Also from that point of view, that’s all you can do, due to lack of any other configuration options. But as it turned out, there is a subtle “bug”, that causes it not to work on any Xiaomi phone (with MIUI and without).
