TEST DELETE

git clone with a specific ssh key

skobes avatar skobes 8 hours ago

A trick I learned for git is:

git clone -c core.sshCommand="ssh -i ~/.ssh/mykey_ed25519" [url]

This configures the cloned repo to use the specified key to talk to the remote. No need to mess with ssh-agent or .ssh/config. Particularly useful if you have keys for multiple Github accounts.

tags.pub - follow global tags

prodromou.pub/@evan https://gitlab.com/evanp/tags-pub

https://fosdem.sojourner.rocks/2026/event/40123f36-a3be-5fdc-871f-feb38b2f8b07 Many ActivityPub servers have a feature to follow a hashtag locally -- subscribing to receive all the content with a particular hashtag that your server knows about, as it arrives. Could we provide a similar feature across the Fediverse? tags.pub is a project to implement that feature -- collecting tagged content and redistributing it by hashtag. In this talk, Evan will discuss the motivations behind tags.pub, its implementation, and outline future steps for global hashtag services.

https://internet.nl/mail/email.com/1738997/

This talk I will go over some FOS (online) tooling to check your mail config. Some common misconfigurations in DNS. Why you should probably want to avoid www CNAME @, and how to config other observations from the biannual measurements of scanning more than 10.000 governmental host names in The Netherlands. After this talk you'll know at least one DNS or security improvement for your own or organization domain, or something to monitor for your email.

Online tools: - the free open source Internet.nl (in the project team) [IPv6, DNSSEC, SPF, DMARC, DKIM, STARTTLS, DANE inbound] - the free open source haveDANE.net (adopted/hosted by platform behind internet.nl) [interactive DANE outbound] - the free open source zonemaster.net [DNS] - the free open source DNSViz.net [DNS]

NEWTOOLS WEBDEV

Sojourner (node/npm used by FOSDEM) is a conference companion, developed by Jarek Lipski.

https://github.com/loomchild/sojourner-web https://sojourner.rocks/

It's inspired by the FOSDEM schedule app written by Will Thompson for the Nokia N900 back in 2010, and discovered by Jarek during his first visit to ULB Solbosch Campus in 2012.

bkt and bash-cache

https://github.com/dimo414/bash-cache

Transparent caching layer for bash functions; particularly useful for functions invoked as part of your prompt.

Bash Cache provides a transparent mechanism for caching, or memoizing, long-running Bash functions. Although it can be used for scripting its motivating purpose is to cache the results of expensive commands for display in your terminal prompt.

https://github.com/dimo414/bkt a subprocess caching utility, available as a command line binary and a Rust library.

T (rust) - a text processing language and utility

I typically find these new sed/awk/grep replacements to be woefully inadequate, but this one seems surprisingly well-designed. I've only skimmed the manual, but there's something..orthogonal about the system, like vim, or array languages. https://github.com/alecthomas/t https://lobste.rs/s/rjw7zn/t_concise_language_for_manipulating_text

Example - top 20 most frequent words, lowercased

Using traditional Unix utilities:

tr -s '[:space:]' '\n' < file | tr A-Z a-z | sort | uniq -c | sort -rn | head -20

The equivalent in t would be:

t 'sjld:20' file

As far as I know, the software used by Fediverse, a decentralized social networking site, makes information public due to its decentralized nature, and as a result, it’s often possible to obtain feeds of the latest information via RSS.

However, the extent to which this is possible varies depending on the software’s capabilities and features, and I was interested in the functionality of each piece of software, so I decided to write this article to resear

ref:xyz OSM

https://wiki.openstreetmap.org/wiki/Key:ref?uselang=en

"ref" stands for "reference" and is used for reference numbers or codes. Common for roads, highway exits, routes, entrances to big buildings etc. It is also used for shops and amenities that are numbered officially as part of a retail brand or network respectively.

This key and variations are frequently used to avoid the use of relations

Key variations

ref=*
int_ref=* – international reference numbers or codes
nat_ref=* – national reference numbers or codes
reg_ref=* – regional reference numbers or codes
loc_ref=* – local reference numbers or codes

For cycle routes:

ncn_ref=* – national cycle network reference
rcn_ref=* – regional cycle network reference
lcn_ref=* – local cycle network reference

country-specific. For example, France uses ref:FR:=*

ref:bic=* bien interes ref:blxx bayern landesamt ref:doc=* new zealand park huts ref:EU:EVSE=* elect charg statin ref:ine=* ine pueblo spain

ref:temples.ru=* amenity=place_of_worship religion=christian Russia Reference for Russian Christian churches in temples.ru catalog

fff mapbox vector tiles spec protobufs (google)

A vector tile is a lightweight data format for storing geospatial vector data, such as points, lines, and polygons

Vector tiles are encoded as Google Protobufs (PBF), which allow for serializing structured data. For clarity, Mapbox Vector Tiles use the .mvt file suffix. The specification details are largely structured around the rules implemented in the base .proto file.

Mapbox Vector Tiles are not related at all to OpenStreetMap PBF files. PBFs are a format, much like XML and can take many forms. Mapbox Vector Tiles and OpenStreetMap PBFs are protobuf files, but conform to completely different specifications and are used in different ways.

less exit with 1 and run a script

03-01-2025 leah blogs: Six hacks for less(1)

Did you ever wish to give feedback from less? Like have a script output some info, and you decide how to go on? Since less always exits with status 0 usually, this I thought this was tricky to do, but the quit action actually can return an arbitrary exit code, encoded as a character.

I bound Q and :cq (like in vim) to exit with status 1:

#command Q quit 1円 :cq quit 1円

Now you can do stuff like look at all files and have them deleted when you press Q instead of q to exit:

for f in *; do less $f || rm $f; done
