Idea: could we have per-directory bash history?
Because sometimes I come back to some project that I only work on intermittently, and I realize that I don't remember where I left off. Having access to the terminal history issued in that directory would help immensely to get up and running again (git history is not always enough).

This is an extremely useful tool for when you need to remove big files from a repo's Git history or when you need to remove passwords and other private data from all commits remote and local.
Note: if you use
--replace-textfunction to specify secret strings and their replacements, each line in this file should not have any spaces surrounding==>. This is important, replacement does not work otherwise.
This tool worked great the few times I have used it.

It has become harder and harder to wipe and reflash modern Android smartphones with an Android OS that the user controls. Partly due to bootloader encryption and the like by the hardware manufacturers (in the name of security) but in my estimation mostly due to every new model using slightly different firmware configuration which is additionally never released open source. This constant moving of the goalposts makes it very hard for the volunteer-based Android modding community to keep up, even just considering yesteryear's model line-up.
My personal take on the current Android modding scene is that apart from Google Pixel phones and a select few other models, it has become practically impossible for a technically literate user to reinstall the OS on their phone, because of the nefarious combination of the manufacturer locking the bootloader and no LineageOS mod being available for the user's model even if the bootloader lock can be defeated.
The result? I think I'm far from alone in maintaining a very old device just because I know I can run LineageOS on it. Also, I really dislike the massive size of Pixel phones along with most other recent phone models.
In light of all this, I really appreciate the efforts the community is putting into wrangling some user-control back on Google's increasingly locked down Android platform, but in the long-term (short-term?) Google's Android may be a lost cause (that's not to say there aren't community efforts to free Android).
Shizuku on the Samsung Galaxy S25 FE
As it happens, I find myself required to use an S25 daily. I have of course installed F-Droid, and changed the default launcher to Kvaesitso. But I had resigned any hope on being able to whittle down the massive list of unwanted apps that came preinstalled on the system. All I could do was block some of them, such as Youtube, and simply hide others from the launcher.
Enter Shizuku! (I only heard about it this week).
And yes, getting it up and running was complicated, but it worked! With Shizuku properly configured, I was able to use Canta to uninstall any app on the phone. And by the way, the list of apps is scaringly long.
In short, I followed the installation instructions for a phone without root access (wireless debugging)
But I quickly discovered that the Shizuku process kept terminating within seconds after starting. So as suggested in the Canta README, I tested the forked Shizuku version and it has been rock solid.

Gratis busskort gav ökad frihet i utsatta områden (KTH)

I wanted to add a follow=Path {/some/symlink} statement to an existing unison job between two Linux machines, one running Ubuntu Noble with unison 2.53.3 and one running Ubuntu Jammy with unison 2.51.5.
However, whichever way I specified the path/name to the symlink, unison would just sync the link itself instead of the contents of the directory it pointed at.
Exasperated, I thought perhaps the version mismatch between the two unison clients may be causing the weird behaviour. So I tested syncing between the Jammy machine and another Jammy machine that also runs unison 2.51.5. And the sync worked as expected.
$ cat .unison/test.prf
root = /home/taha/KVT
root = ssh://luxor//media/bay/taha/KVT
follow = Path projects/devOn the remote we have the following symlink:
/media/bay/taha/KVT/projects/dev -> /media/bay/taha/projects/ansible/devFiguring out how to use multiple password stores, each with their own GPG key.
And importantly, how to make the password stores work transparently with the Android app?
The point is to be able to share a specific folder (and all its subfolders) with a collaborator without exposing the secrets in the rest of the passwordstore.
🚨 I just found out, the Android Password Store has been retired by its author https://github.com/android-password-store/Android-Password-Store/discussions/3260 🚨
But there is a fork! https://github.com/agrahn/Android-Password-Store with an app on the F-Droid store https://f-droid.org/packages/app.passwordstore.agrahn
Some ideas from the interwebs:
- symlink folders into the passwordstore
- use direnv to set the environment var PASSWORD_STORE_DIR
- use git submodules
I tried the symlink approach: it works nicely enough on the desktop computer, but not at all on Android with the Passwordstore app.
I considered but did not test the other ideas.
After some more browsing and reading I realized that the pass init command does everything I want.
Starting from the entire passwordstore being encrypted using key A.
Then, assuming you have created GPG key B, re-encrypt folder aaa in passwordstore:
$ pass init --path=aaa BThat's it. Now only key B can decrypt any secrets in the aaa directory (recursively). We can re-encrypt using multiple key by simply listing them, pass init --path=aaa B C D.

[the] technology is a facilitating thing. It's like trying to describe how a bicycle works, rather than why you ride it.
Instead, what the Fediverse is, is a place to have conversations online without algorithms, AI, and ads getting in the way.
Which is increasingly a rare thing online.
Almost the entirety of the internet, from SEO on the web to YouTube to TikTok to Spotify to Instagram and X and Facebook, has been turned into a race to game an algorithm designed to sell ads.
What makes the Fedi unique is that it's not that.

- does not federate with the Fediverse (unless the user herself sets up a "bridge")
- false promise of decentralization using the AT protocol
- your block list is publicly visible
- algorithms (controlled by the platform owner) are still king
- heavily financed by crypto-bros and other opaque sources
As a step on the journey away from Twitter it is not too bad. But please don't stop there - continue the journey towards the free, open web.

Despite what this report says, I would not say that "Threads and Bluesky" are "services in the fediverse". Threads does federate with the Fediverse, but in my opinion that is only a cynical effort by Facebook to "embrace, extend, and extinguish."

Let's say you have a list of dicts, e.g.,
unison_jobs:
- name: sites
roots:
- "root = {{ ansible_env.HOME }}/sites"
- "root = ssh://luxor/{{ ansible_env.USER }}/sites"
opt: "-auto"
- name: projects
roots:
- "root = {{ ansible_env.HOME }}/projects"
- "root = ssh://luxor/{{ ansible_env.USER }}/projects"
opt: "-auto"and you want to reference the first root element of the job named projects.
Notice that I want to reference the dicts by its name value and not by its index number (so not simply unison_jobs[n]).
This is not that hard, but enough time passes between occurrences that I forget the specifics and have to look it up again. I hope by writing it down that I will strengthen my ability to recall, or at least give myself a fixed spot to look for it.
{{ unison_jobs | selectattr('name', 'equalto', 'projects') | map(attribute='roots') | first }}How does map(attribute='somekey') work? Does it return a list even if the referenced key is a non-list item? Yes, by default it always returns a list. Does that mean we can set some option to disable that behaviour? Does not look like it, no.
