Tribal Knowledge? Getting the public keys from github and gitlab users from their username

Posted by jpluimers on 2025/04/03

Learned a while ago: if you have the username from a GitHub or GitLab user, you can download interesting that sometimes can make life easier (but not necessarily more secure):

  • github.com/username.keys gives you their public SSH keys
  • gitlab.com/username.keys gives you their public SSH keys
  • github.com/username.png gives you their profile image

And that there are tools like gh, glab and age that can make direct use of them.

I love Twitter, so thanks for these for teaching me these little tricks:

Some HTTP redirect checking sites compared

Posted by jpluimers on 2025/04/02

 

Every now and then I want to check how a URL redirect, for instance when checking out why a domain failed loading in browsers a while ago because of certificate problems:

The thing was that back then, the site officially did not have a security certificate, but somehow the provider had installed a self-signed one. Most web-browsers then auto-redirect from http to https. Luckily the archival sites can archive without redirecting:

When querying [Wayback/Archive] redirect check – Google Search, you get quite some results. These are the ones I use most in descending order of preference and why they are at that position:

On accessibility (thanks Bianca Prins!) and archivability.

Posted by jpluimers on 2025/02/27

A long while ago, I participated in a Twitter thread that started with a translation of some important accessibility posts by Bianca Prins, then extended it to the concept to archivability:

[WayBack] Thread by @jpluimers: “I am going to first translate this, then extend this to archivability…. @jpluimers […]” #UXdesign #accessibility.

TL;DR

  1. make sure what you create is accessible
  2. ensure your (online) content is archivable
  3. help archiving content

Let’s go

Old xs4all stuff

Posted by jpluimers on 2024/11/29

In the past xs4all.nl had a shell server. In the shell you had a WWW directory which was the route of your personal web-site.

For instance, I had a file there in ~jp/WWW/route/route.html which was served at:

Almost 25 years after KPN bought xs4all, it switched off the shell servers and these links, so I was glad with this warning [Wayback/Archive] Koen de Jonge on Twitter: “Morgen stopt #kpn4all met het aanbieden van shellaccess. Wij willen dat met #Protagio ook gaan aanbieden. Wil je ook #shellacces houden, kijk dan snel op: … #eerlijkecloud”

IPv4 subnet/CIDR table from OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation …”

Posted by jpluimers on 2024/11/27

I wrote about programs and scripts doing IPv4 subnet calculation, but sometimes it is easier to have a table at hand, so here is the one I found at [Wayback/Archive] OccupytheWeb on Twitter: “Network Basics for Hackers: Subnetting, Subnet Masks and CIDR Notation #networks #networkbasics #subnetting #infosec #networks4hackers #cyberwarrior #cyberwarrior #networkbasics #networkbasics subnet”

Reminder: check out what GitLab has put in place for “dormant” or “inactive” repositories

Posted by jpluimers on 2024/10/31

A few of my git repositories and technical surroundings (like pages) should outlast my life expectancy, for instance the ones supporting the IT infrastructure of my mentally retarded brother after I pass away.

Most of the involved repositories have no write-activity (they are either documentation that the people can use after I passed away, or are semi-static web-pages that require TLS in order to keep functioning; GitLab provides an automatic update mechanism for that which is based on Let’s Encrypt).

Summer 2022, GitLab caused quite some stir when they planned to first delete dormant repositories. Links on tose below.

Of course I could move to GitHub, but that lacks access control through project hierarchy provided by GitLab and could implement a similar repository dormancy scheme in the future.

Using an external “keepalive” mechanism only induces a game of walls and ladders [Wayback/Archive] (likely requiring intervention after I die) and also makes the infrastructure more brittle so I proposed a lump sum plan.

Some links for my reminder:

Thread by @troyhunt: the Internet Archive was breached, DDoSed and defaced – reset your passwords (it’s the same account as for their Wayback Machine)

Posted by jpluimers on 2024/10/10

was it a little more than a DDoS?

Despite messages of the Internet Archive and Wayback Machine were fully up again after the DDoS in the last few days (usually starting at around 20:00 UTC, lasting for hours at a time, but today at 10:00 UTC), countermeasures of their password breach at the end of September and defacement yesterday, today they still had Wayback Machine archiving issues:

Google Search teamed up with the Internet Archive’s Wayback Machine: the good, the bad, the ugly

Posted by jpluimers on 2024/09/16

tTL;DR: Google Search also (after 3+ manual steps) showing the most recent Wayback Machine archived page for a web-page search result, helps tremendously for pages that are temporarily off-line (everyone knows how stable the cloud – someone else’s computers – or on-premise computing is), but takes too many steps and still doesn’t index the full Wayback Machine.

But there is a Clint Eastwood movie title here, even after the devastating fact that Google now off-loads its Google Cache to the Wayback Machine (which many sites refuse to be archived in), as per [Wayback/Archive] Google will no longer back up the Internet: Cached webpages are dead | Ars Technica:

The good
