This post shows how to bisect a Fedora kernel to find the source of a regression. I needed that recently and I found no good guide, so I’m at least capturing my notes here, perhaps you find it useful. This approach can be used to identify which exact commit caused a bad kernel behavior on … Continue reading Bisecting Fedora kernel
After the last IRC changes, some of the Matrix->IRC bridges got disconnected, some rerouted (to Libera.Chat), and everything is work in progress. I’ve been a Matrix user for the past few months, and I definitely don’t want to go back to IRC. But in order to stay connected to the Fedora community, some steps were … Continue reading Connecting to Libera.Chat through Matrix
Side-by-side diffs are more readable to me than in-line diffs. Long time ago, I started using Meld to display them when working with git. But I always needed to manually specify branch or commit names. This week I finally spent some time and found a way to invoke Meld directly from tig, so that I … Continue reading Show a side-by-side git diff on any commit in tig using Meld
As previously announced, Taskotron (project page) will be shut down today. See the announcement and its discussion for more details and some background info. As a result, certain tests (beginning with “dist.“) will no longer appear for new updates in Bodhi (in Automated Tests tab). Some of those tests (and even new ones) will hopefully … Continue reading Taskotron is EOL (end of life) today
I’ve already written about this in 2017, but things got simpler since then. Time for an update! If you use virtual machines, your disk images just grow and grow, but never shrink – deleted files inside a VM never free up the space on the host. But you can configure the VM to handle TRIM … Continue reading Automatically shrink your VM disk images when you delete files (Fedora 32 update)
Hello, this is a reminder that you can easily stay informed about important upcoming QA events and help with testing Fedora, especially now during Fedora 32 development period. The first obvious option for existing Fedora contributors is to subscribe to the test-announce mailing list. We announce all our QA meetings, test days, composes nominated for … Continue reading Stay informed about QA events
In Firefox 70, there is a new feature called kinetic scrolling [1]. If you scroll the web page using trackpad (or possibly touchscreen), the scroll event will not stop immediately after releasing your fingers, but it will gradually slow down, as if a rotating wheel slowly stops. After using it for a short while, I … Continue reading Disabling kinetic scrolling in Firefox
If you have a Windows 10 installation, you might not be able to read all files on its NTFS partition. Under certain conditions, Microsoft compresses system files with new compression algorithms which the ntfs-3g driver can’t currently read. Files are displayed with question marks when listed using ls, and you’ll see Input/output error or unsupported … Continue reading New Fedora package: ntfs-3g-system-compression
Recently a bug in rtkit packaging has been fixed, but the update will fail on all Fedora 29 pre-release installation that have rtkit installed (Workstation has it for sure). The details and the workaround is described here:

If you submit a new Fedora update into Bodhi, you’ll see an Automated Tests tab on that update page (an example), and one of the test results (once it’s done) will be from rpmlint. If you click on it, you’ll get a full log with rpmlint output. If you wish to whitelist some errors which … Continue reading Whitelisting rpmlint errors in Taskotron/Bodhi
Update: This got significantly simpler with newer qemu and virt-manager, read an updated post. If you use VMs a lot, you know that with the most popular qcow2 disk format, the disk image starts small, but grows with every filesystem change happening inside the VM. Deleting files inside the VM doesn’t shrink it. Of course … Continue reading Automatically shrink your VM disk images when you delete files
