Classic Web – Screenshots of classic websites and blogs from Dot-Com, Web 2.0 and the 2010s.

Classic Web is a fun account to follow on Mastodon. Curator Richard MacManus posts half a dozen or so screenshots per day of, well, classic websites from the late 1990s and 2000s. Makes me feel old and young at the same time.

My feeds have the Access-Control-Allow-Origin: * header, do yours? 🫵😠

I answered the above shoutout from David Bushell by adding the following statement to my nginx config:

if ( $uri ~* ^/rss\.xml$ ) {
	more_set_headers "Access-Control-Allow-Origin: *";
}

The slides from the Agentic Coding presentation inspired my inner frontend developer and I created a new style for the blog. ✨

Things are still a bit rough, not everything is fitting nicely yet.
General functionality should work, but please let me know if you encounter something that is broken.

I researched various CSS tricks to achieve the design change without changing any HTML.
After recreating the PDF style in CSS, I double-checked the origin of the presentation layout.
And turns out that it is based on the unnamed community theme created by Elio Struyf for Slidev. 😃

In spirit of the More Purple Links, Please article, I've added some purple color to the visited link style on the blog.
To blend in with the existing text color, I've used the color-mix() CSS function:

:root {
	--body-text-color: #454545;
	--body-visited-link-color: color-mix(in srgb, var(--body-text-color), #518 75%);
}
a:visited {
	color: var(--body-visited-link-color);
	text-decoration-color: var(--body-visited-link-color);
}

Inspired by the post from David Bushell, I spent some time to add syntax highlighting to the blog.
It has been an item on my todolist for a long time.
I've always hesitated as I wanted to avoid having server-side rendering that generates a big amount of HTML tags just to add some color.
But now with the approach of using the new CSS Custom Highlight API, this is no longer an issue, as no additional HTML tags are injected.

To make things easy I built my solution on top of the custom <syntax-highlight> element.
This makes it very smooth to add syntax highlighting in a post.
For example the following is the source code for the helloworld.c post:

<pre><syntax-highlight language="c">void main(){puts("Hello World.\n");}</syntax-highlight></pre>

The custom element uses Prism to tokenize the text, which brings support for over 250 different languagues.
This is great, as I've accumulated quite a collection of different code snippets over the years.
There is some Terraform, Python, Perl, PHP, Bash, CSS, Javascript, HTML, Nginx and plenty of others 😎

Inspired by the Add Your Email Address to Your RSS Feed article, I added the email element to the Atom feed of the blog (the RSS feed already had the email address). Enjoy 🎉

In the Agentic Coding article, Simon Willson talks about the Agentic Coding: The Future of Software Development with Agents YouTube talk from Armin Ronacher.

I picked up a bunch of useful tips from this video:

• Armin runs Claude Code with the --dangerously-skip-permissions option, and says this unlocks a huge amount of productivity. I haven't been brave enough to do this yet but I'm going to start using that option while running in a Docker container to ensure nothing too bad can happen.
• When your agentic coding tool can run commands in a terminal you can mostly avoid MCP - instead of adding a new MCP tool, write a script or add a Makefile command and tell the agent to use that instead. The only MCP Armin uses is the Playwright one.
• Combined logs are a really good idea: have everything log to the same place and give the agent an easy tool to read the most recent N log lines.
• While running Claude Code, use Gemini CLI to run sub-agents, to perform additional tasks without using up Claude Code's own context
• Designing additional tools that provide very clear errors, so the agents can recover when something goes wrong.
• Thanks to Playwright, Armin has Claude Code perform all sorts of automated operations via a signed in browser instance as well. "Claude can debug your CI... it can sign into a browser, click around, debug..." - he also has it use the gh GitHub CLI tool to interact with things like GitHub Actions workflows.

I would add to this list a link to the Agentic Coding Recommendations blog post of Armin.

It supports both single variables and more complex expressions. Here’s a few examples:

>>> x = 42
>>> f"{x=}"
'x=42'
>>> f"{1+2=}"
'1+2=3'
>>> f"{(1+2)*3=}"
'(1+2)*3=9'

I've long had a list of "magic numbers" which show up in a bunch of places, and even made a post about it back in November of 2020. You ever wonder about certain permutations, like 497 days, or 19.6 years, or 5184 hours, and what they actually mean?

I've been doing that stuff by hand in a calculator and finally decided to just do it in Javascript and put it online for anyone to try.

So, here's my latest waste of CPU cycles:

Someday I should find the motivation to export an OPML file from the reader and make it available.
The full OPML list would be way too big for the sidebar, so a dedicated place would need to be found. 😅

benjojo does some clever data analysis for Picking uncontested private IP subnets with usage data.
He not only gathers the usage data of the various subnets, but also provides a nice tool to get a /24 subnet from the list that has no known users.

And to top it off the article also provides the underlying data.
A Zip file with the /24 subnets with number of known users (local copy).
And the distilled list of subnets that have no known users (local copy).

As part of my migration to Bunny CDN for andreas-jaggi.ch, I also moved the DNS zone over.
There are not many records in the zone, but one which turned out to be a bit more tricky was the CAA one.

I wanted to use the following Terraform snippet to create it:

resource "bunnynet_dns_record" "andreas_jaggi_ch_CAA" {
  zone  = bunnynet_dns_zone.andreas_jaggi_ch.id
  name  = ""
  type  = "CAA"
  value = "0 issue \"letsencrypt.org;validationmethods=http-01\""
}

But this always failed with a cryptic error message during terraform apply:

│ Error: Unable to create DNS record
│
│   with bunnynet_dns_record.andreas_jaggi_ch_CAA,
│   on dns.tf line 22, in resource "bunnynet_dns_record" "andreas_jaggi_ch_CAA":
│   22: resource "bunnynet_dns_record" "andreas_jaggi_ch_CAA" {
│
│ A tag can be a maximum of 50 ASCII characters.

After some head-scratching I figured out that the Terraform provider has dedicated fields for the flags and tag parts of the CAA DNS record.
And it insists on them being used this way:

resource "bunnynet_dns_record" "andreas_jaggi_ch_CAA" {
  zone  = bunnynet_dns_zone.andreas_jaggi_ch.id
  name  = ""
  type  = "CAA"
  tag   = "issue"
  flags = 0
  value = "letsencrypt.org;validationmethods=http-01"
}

With this in place, it worked fine.
And it prepared me also for the MX record where a similar approach is required.

For andreas-jaggi.ch I wanted to try out Bunny CDN.
Everything went very smooth and I nicely used Terraform to configure Edge Rules blocking all unwanted access.
As andreas-jaggi.ch does not have much content this resulted in a list of allowed files similar to this:

resource "bunnynet_pullzone_edgerule" "andreas_jaggi_4" {
  pullzone    = bunnynet_pullzone.andreas_jaggi.id
  description = "block not(known good) http://www.andreas-jaggi.ch"
  enabled     = true
  match_type  = "MatchNone"
  actions     = [{ type = "BlockRequest", parameter1 = null, parameter2 = null, parameter3 = null }]

  triggers = [
    {
      match_type = "MatchAny",
      patterns = [
        "http://www.andreas-jaggi.ch/",
        "http://www.andreas-jaggi.ch/favicon.ico",
        "http://www.andreas-jaggi.ch/robots.txt",
        "http://www.andreas-jaggi.ch/security.txt",
      ],
      type = "Url", parameter1 = null, parameter2 = null
    },
  ]
}

After this I did setup the www subdomain as CNAME and added it as additional hostname to the CDN Pullzone.
But the process to get a Let's Encrypt certificate for the www subdomain always failed with an error.

This is where I messed up.
Turns out my Edge Rules blocking all unwanted access also blocked the Let's Encrypt validation requests. 🤦

Once I realized this (which took a shamefully long amount of time), I added an entry to the Edge Rules for the .well-known/acme-challenge/ subpath:

resource "bunnynet_pullzone_edgerule" "andreas_jaggi_4" {
  pullzone    = bunnynet_pullzone.andreas_jaggi.id
  description = "block not(known good) https://www.andreas-jaggi.ch"
  enabled     = true
  match_type  = "MatchNone"
  actions     = [{ type = "BlockRequest", parameter1 = null, parameter2 = null, parameter3 = null }]

  triggers = [
    {
      match_type = "MatchAny",
      patterns = [
        "http://www.andreas-jaggi.ch/",
        "http://www.andreas-jaggi.ch/favicon.ico",
        "http://www.andreas-jaggi.ch/robots.txt",
        "http://www.andreas-jaggi.ch/security.txt",
        "http://www.andreas-jaggi.ch/.well-known/acme-challenge/*",
      ],
      type = "Url", parameter1 = null, parameter2 = null
    },
  ]
}

With this in place, the process worked immediately and the www subdomain now also serves encrypted traffic. 🔐

In the You can style alt text like any other text article, Andy Bell showcases how the alt test of images can be styled with CSS.
And then goes on to provide a smooth gracefully degrading experience by leveraging JavaScript to style image loading errors differently than successfully loaded images.

I like that CSS gives us plenty of opportunities to add finer details when we want them. One of those finer details is making the experience of an image not loading a little better.

The alt text is surfaced on the page when an image fails to load. It’s yet another reason to write good alt text and really hone your skills in creating a user-focused experience by being descriptive.

What’s happening here is I’m hooking a function up to the <img>’s built-in onerror event. When that event fires, I’m setting a data-img-loading-error attribute.

Here comes a handy utility: timeout. As the name suggests, this command adds a timeout to other commands. You specify the time limit you want to wait for a command and if that time passes, timeout sends a signal to terminate it and exits with non-zero. By default, timeout sends SIGTERM, but you can change it with the --signal flag, e.g. timeout --signal=SIGKILL 1s foo.

For example, timeout 1s sleep 5 will send the SIGTERM signal to sleep after 1 second.

After a bit more than 13 years I now removed Disqus from the blog.
Over these years, it only contributed 36 comments.
Most of them around a single post that made it onto the frontpage of Hacker News and Reddit.

I'll extract these comments from the export file of Disqus.
Then backfill them as static entries to the corresponding posts so they are preserved.

In the future I might add another way to comment/contribute directly on the blog.
For now, please use the communication channels listed on the About page.

This year, I missed the CSS Naked Day.
I very much like the idea of ensuring my blog is also readable without CSS.
Thus to make sure I'll not miss it next year, I've added the following snippet into my nginx config:

set $csp_style "'unsafe-inline' blog.x-way.org https://*.disquscdn.com https://gist.x-way.org/assets/";
if ( $time_iso8601 ~* ^20[0-9][0-9]-0?4-0?9T.*$ ) {
	set $csp_style "'none'";
}
include /etc/nginx/conf_includes/x-way.org_security_headers;

It's using a very basic mechanism to ensure no CSS is shown on April 9 next year (or any other year)
First it checks if the date is April 9, and if yes it sets the variable for the style-src Content-Security-Policy header to 'none'.
Which forbids the browser to load any CSS when rendering my blog.

Now let's see how it looks next April 9th ☺️

Being only an occasional coffee drinker, I lack any coffee making machinery at home. Not even some instant-coffee.
Thus this text is going to be less extensive than the inspiration post from Mike.

And quite often in one of the nice cafes in Zurich.

In the Passkeys for Normal People article, Troy Hunt explains in simple terms how Passkeys work.

At the end it briefly touches on using hardware U2F keys as well 🔐

Added some subtle links to the next and previous posts.
Turns out this is a built-in feature of Jekyll, which I never thought about using so far :-)

Here's the snippet which I just added to my custom post layout template:

<footer class="navfooter">
<nav>
{%- if page.next.url %}
<a rel="next" href="{{ site.url }}{{ page.next.url }}" title="{{ page.next.title | strip_html | escape_once }}">&larr;</a>
{% endif -%}
{%- if page.previous.url %}
<a rel="prev" href="{{ site.url }}{{ page.previous.url }}" title="{{ page.previous.title | strip_html | escape_once }}">&rarr;</a>
{% endif -%}
</nav>
</footer>

(Only thing left now, is to tame the ugly Disqus comments section so these links become more visible…)

The Yeah, I Made It Lilac post inspired me to try to do something similar here. I was wondering how complicated a post-specific style-sheet would be.
Turns out it can be quite simple.

First I changed my current style-sheet to use custom properties to define the colors in the :root pseudo-class. This allows to make simple modifications without having to re-define a style-sheet from scratch.
Basically it is enough to re-define some of the custom properties with new colors, and everything else inherits them.

I already had some templating logic in place allowing to inject custom stylesheet fragments (eg. for the About and Statistics pages). And a positive surprise, the logic behaves as desired when used for blog posts as well.
The custom stylesheet is injected when the page of the post is loaded, but is not injected when the post is shown as part of a collection (home page, archives, categories etc.). Thus limiting the change to exactly the page of the post, and not messing with the style-sheet of other pages.

So in the end the lilac.css file which is injected for this post is quite simple:

:root {
	--border-color-3: #6952a7;
	--border-color-2: #a076c6;
	--border-color: #ddabe2;
	--pre-bg-color: #f7f7f9;
}

You’re in a rush and you need to grab a bottle of wine for a special occasion. You’ve got $40 and no preference for red or white, but you like wines with animal labels. Which wine are you buying?

We used ChatGPT Vision to identify animals on close to 1,500 wine labels to see if we could predict the price and quality of a bottle based on the animal on the label.

TL;DR: New Zealand wines provide good quality for reasonable price. Cats are high quality.

In his latest article Russ Cox explains the concept of using Differential Coverage for Debugging.
It's a clever approach using the difference of the coverage output between two test runs, to directly highlight the lines of code that contributed to a bug.

# collect coverage of a passing test run (skip the failing test)
go test -coverprofile=c1.prof -skip='TestAddSub$'

# collect coverage of a failing test run (run the failing test only)
go test -coverprofile=c2.prof -run='TestAddSub$'

# calculate the coverage difference between the runs (so only the code of the failing test gets highlighted)
(head -1 c1.prof; diff c[12].prof | sed -n 's/^> //p') >c3.prof

# display the code in a web browser (green/covered code did contribute to the failing test)
go tool cover -html=c3.prof

Hallucinated package names fuel 'slopsquatting'.

All that's required is to create a malicious software package under a hallucinated package name and then upload the bad package to a package registry or index like PyPI or npm for distribution. Thereafter, when an AI code assistant re-hallucinates the co-opted name, the process of installing dependencies and executing the code will run the malware.

To ensure I don't forget to rotate/extend one of the subkeys of my PGP key, I created a little monitoring tool.
I wanted something that reminds me well before my published PGP key shows sign of expiry.
And I wanted it built in a way so it can be used in a simple cronjob to continuously nag me until the expiring key has been replaced. 😈

So pgp-expiry-monitor was born.
It takes two parameters, the URL of a PGP key and the number of days in advance it should start warning.
If all is fine and the PGP key does not contain any expiring keys, it returns without any output. Thus ideal for a cronjob.

Discovered a very helpful debugging utility: GPG/PGP Decoder

The hosted version helps to quickly find out which subkey was used to sign a message.
I used it to check that this signature contains the fingerprint and ID of my new subkey 🔐

One of my yearly digital routines is to update my GPG key.
Part of this involves adding new ECC subkeys (ECDH and EdDSA).
These are the commands I used this time (so I don't have to look them up again next year).

% gpg --edit-key 401F1D483C69BF624364CC01E9A68DCFA3A54203

gpg> addkey
Select number 10 ECC signing
Select number 1 Curve 25519
Select a validity of 2y

gpg> addkey
Select number 12 ECC encryption
Select number 1 Curve 25519
Select a validity of 2y

gpg> save

After this the new subkeys are available and the updated public key can be exported and published.

Dione - Rewinder

Saw this Blog Questions Challenge about Travel Adventures and it piqued my interest.

1. What's the silliest souvenir you've ever brought back from a trip?
2. If you could teleport anywhere right now, for a day trip, where would you go?
3. What's the weirdest food you've ever tried while traveling?
4. What's the most memorable "wrong turn" you've taken on an adventure?

What's the silliest souvenir you've ever brought back from a trip?
More stupid than silly. On my way to Australia, I bought some very nice honey in Mauritius.
It promptly got confiscated by the Australian Border Force as their biosecurity does not allow the import of honey.

If you could teleport anywhere right now, for a day trip, where would you go?
Off the top of my head this would be Île des Pins in New Caledonia.
I spent two very nice days there in 2018 while doing an extended New Caledonia weekend trip during my last rotation in Sydney.

What's the weirdest food you've ever tried while traveling?
Probably crocodile. This was in 2013 while traveling in Australia.
There was a australian game meat BBQ organized for us tourists, and various meats could be tasted.
Didn't particularly like the crocodile, it tasted a lot like chicken.
The hosts explained that crocodile usually tastes like the thing it eats, and these ones were fed with chicken, cue them tasting like chicken.

What's the most memorable "wrong turn" you've taken on an adventure?
While traveling by train to Amsterdam, somewhere outside Frankfurt there was a problem with the tracks.
The ICE I was on, returned halfway to Frankfurt and then used a very long but scenic route along the Rhine river to reach Koeln.
Overall the journey to Amsterdam took 4 hours longer than planned, but we got to see some very pitoresque villages along the river.

How to write exceptional documentation

I recently tried out Claude Code for both some personal project as well as some work project.
Was very impressed how far the AI coding assistants have come already.
Looks like a powerful tool when used by an experienced software engineer.

I've been using Claude Code for a couple of days, and it has been absolutely ruthless in chewing through legacy bugs in my gnarly old code base. It's like a wood chipper fueled by dollars. It can power through shockingly impressive tasks, using nothing but chat. [...]

Claude Code's form factor is clunky as hell, it has no multimodal support, and it's hard to juggle with other tools. But it doesn't matter. It might look antiquated but it makes Cursor, Windsurf, Augment and the rest of the lot (yeah, ours too, and Copilot, let's be honest) FEEL antiquated.

If your content is only on social media, I'm not going to see it by Cory Dransfeldt.

If you only post on social media, I won't see it. If you don't have an RSS feed, I won't follow it, I won't subscribe to it. I don't want want your app because I don't want a homescreen full of apps for publications and platforms.

I don't have a fear of missing out. I am missing out. I've come to terms with that. Algorithms can be a convenient means of surfacing relevant content. They can be. But those algorithms are tailored by platform operators whose aims are (very) often not aligned with yours. They tailor content discovery purely to keep you hooked. Eyeballs to ads, money to shareholders.

Or as commented on by Mike Sass:

Same same. Just get an RSS feed, and stop relying on the hegemonic platform silos.

There's a corner of the Internet where people have been reclaiming their digital independence by hosting their own websites and promoting the idea of owning your own content—it's called the IndieWeb.

This movement promotes the idea that individuals should control their own digital presence through personal websites. But every time this topic comes up in online discussions, someone inevitably claims that the IndieWeb hasn't taken off!

The IndieWeb doesn't need to go mainstream to be meaningful. It's a celebration of a more personal, decentralised, and creative world wide web. And for those of us who still care about these values, it is already meaningful.

Finding Flow: Escaping Digital Distractions Through Deep Work and Slow Living – a personal guide to reclaiming focus in the age of endless temptation.

The Stolen Focus: Why You Can’t Pay Attention book by Johann Hari which inspired this article goes on the /reading list 📖

“I urge you to please notice when you are happy, and exclaim or murmur or think at some point, ‘If this isn’t nice, I don’t know what is.’”
— Kurt Vonnegut

It’s a simple two-step process:

1. First, notice. Notice that things are good. Notice the feeling of pleasure. Notice today’s perfect temperature. Notice the art project your child is sharing with you.
2. Then, say thank you. To the person you’re with, for the life you live, to the reality you’ve been blessed with, to the God you feel must be there.

And if none of those feel like the right objects of gratitude, that’s okay too. Simply murmur to yourself, ‘If this isn’t nice, I don’t know what is.’

Ruben Schade published a post with answers to the terminal survey that Julia Evans recently conducted.
Inspired by this, below are my answers to these questions.

How long have you been using the terminal?

Since 2002.

Which shells do you use?

zsh (on my laptop/workstation), bash (on servers).

Do you use your system’s default shell?

No and yes (was using zsh before macOS made it the default).

What OS do you use a Unix terminal on?

macOS, Linux.

What Terminal emulators do you use?

Terminal.app, GNOME Terminal.

Do you use a terminal-based editor?

Yes, vim.

Do you customise your terminal’s colour scheme?

Yes, my current scheme evolved from the 2003 Gentoo default scheme.

If your terminal get messed up, what do you do?

Run reset.

What terminal settings do you customise?

PATH, environment variables, alias, the prompt, custom functions, history, syntax-highlighting.

Do you use job control?

No. Tried it sporadically, but not really my thing, rather using a terminal multiplexer.

Do you manage your files using the terminal, or a GUI file manager?

Basic local operations mostly in the GUI. Anything advanced, automated, remote or mass-operations in the terminal.

Which of these environment variables have you set intentionally?

PATH, EDITOR, and some others:

% grep export zshrc/zshrc|sed -e 's/=.*//'
export GIT_AUTHOR_NAME
export GIT_COMMITTER_NAME
export TZ
export PERL5LIB
export GOPATH
export LOCKPRG
export SAM_CLI_TELEMETRY
export JAVA_HOME
export RSYNC_RSH
export CVS_RSH
export EDITOR
export USE_EDITOR
export CVSEDITOR
export BROWSER
export LESS
export HOMEBREW_NO_ANALYTICS
export WWW_BROWSER

Do you use vi mode in your shell?

Yes.

How do you navigate files in less?

/ to search, then mostly spacebar to scroll and the occasional j/k.

How do you use pipes?

sort, uniq, tr, sed, find with xargs to parallelise, and awk.

Do you use a terminal multiplexer?

screen (still trying to migrate to tmux, eventually).

What’s the most frustrating thing about using the terminal for you?

Scripts assuming GNU specific parameters/tools on macOS.

Whenever somebody sends you a pull request, give them commit access to your project.

The Pull Request Hack

In the Conventional Commits article, Mike Perham explains how git commit templating can be used to support commit message consistency.

The key part is the template statement in the ~/.gitconfig:

[commit]
	template = ~/.gitmessage

This references the ~/.gitmessage file which is used as template for every new commit message.
For Conventional Commits, the following can be useful:

# type(subsystem): short description
### Types
# feat: A new feature
# fix: A bug fix
# docs: Documentation only changes
# build: Changes that affect the build system or external dependencies
# ci: Changes to our CI configuration files and scripts
# perf: A code change that improves performance
# refactor: A code change that neither fixes a bug nor adds a feature
# style: Changes that do not affect the meaning of the code
# test: Adding missing tests or correcting existing tests

In Re-ordering Git commits, Cassidy Williams explains nicely how interactive Git rebasing can be used to re-order Git commits.

TL;DR:

git rebase -i HEAD~4

In The beauty of goofy diagrams Einenlum explains how a diagram drawn in a more casual style, can support conveying information easier to the audience.

The thing is, I’m more and more convinced that the style of a presentation matters. Even before looking at the content itself, the style puts you in a particular mood.

[...] To me, although they convey the same content, the first one creates a sense of seriousness and gravity. It feels like only clever people can understand it. I’m already a bit tense and I feel like I need to focus. I almost take a deep breath and say to myself “okay, you can do it”. I feel dumb but I feel that with enough curiosity and hard work I can understand the content.

The second one, on the other hand, makes me feel more relaxed and probably more curious. The topic seems easier to grasp and I’m quite confident I can understand it. It doesn’t mean it brings more clarity: the first diagram is actually probably clearer but the content has more chance of reaching my brain with the second one because I’m more open to it.

I upgraded the blog to the newest Jekyll 4.4.0 which was released yesterday.
Unfortunately this first resulted in the following segfault while running jekyll build 🙈

/usr/gem/gems/sass-embedded-1.83.4/ext/sass/embedded_sass_pb.rb:11: [BUG] Segmentation fault at 0x0000000000004410
ruby 3.1.1p18 (2022-02-18 revision 53f5fc4236) [x86_64-linux-musl]

Turns out that this is a known problem of the google-protobuf gem (which is used by jekyll-sass-converter which is part of the default Jekyll).
Luckily there is a workaround.
Adding the following to my Gemfile fixed it 🎉

gem 'google-protobuf', force_ruby_platform: true if RUBY_PLATFORM.include?('linux-musl')

Russel Baylis shares this helpful article about their learnings regarding improving the working environment to reduce eye strain.

I work from home everyday, I am susceptible to eye strain, eye pain, and dizziness. Having a working environment that’s as easy on my eyes as possible is of critical importance. I'd like to share what I've learned over the years in hopes that it can be helpful to you if you work from home, and like many, have experienced WFH eye strain.

1. An even, diffused lighting environment is best for the eyes
2. When it comes to light brightness, too much is just as problematic as too little
3. Use natural light wherever possible
4. Quality of artificial light matters
5. The best lighting for camera, is not necessarily the best lighting for ergonomics
6. Even the perfect lighting environment will fatigue you — take breaks, and take care of yourself

When connecting to an older SSH device the following 'unable to negotiate' errors occurred. They indicate that my client-side config does not allow the (old/obsolete) methods offered by the device.

Unable to negotiate with 10.222.23.2 port 22: no matching key exchange method found. Their offer: diffie-hellman-group-exchange-sha1,diffie-hellman-group1-sha1,diffie-hellman-group14-sha1

This can be fixed by enabling one of the old key exchange methods:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 10.222.23.2 

Unable to negotiate with 10.222.23.2 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss

This can be fixed by additionally enabling one of the old host key types:

ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 -oHostKeyAlgorithms=+ssh-rsa 10.222.23.2

terra tauri quotes from the Platform Engineering book:

If you only promote people who solve big technical problems, you’re going to have a hard time retaining the people who do the work to smooth out the usability edges, actively listen to the customer teams, and adjust their work priorities to fix the stuff that is causing the most pain. So, look closely at what you are celebrating, compensating, and promoting, and make sure you are including work that makes the product better, whatever that looks like, even if it isn’t the hardest technical bits. You may even want to reevaluate your engineering ladder to make sure the expectations at each level reflect all of the skills you now demand. Remember, this is a cultural change, and cultural changes that don’t involve changes to what is valued (as seen by what you recognize and reward) are destined to fail.

Looks like this might be a candidate for my /reading list.

My new favorite type of CAPTCHA: DOOM CAPTCHA

During casual surfing I found this article from Brain Baker explaining their revised backup strategy.
The most interesting part was the brief mention of PhotoSync used to sync photos to their Linux system.

This came just at the right moment, as I was exploring options how to get photos from an iPhone to a Linux machine as seemlessly as possible.
Previous attempts with ifuse/libimobiledevice didn't work reliably, and uploading the photos to iCloud and somehow scraping/downloading them again doesn't look very future-proof either.
Thus very happy about PhotoSync which runs on the iPhone and talks a plethora of protocols on the other side (in my case I opted for SFTP).

It is a freemium app with paid in-app purchase for the pro/premium features (raw photo sync and autosync in the background).
Based on the good reviews and initial functionality testing of the free version I decided to fo for the one-time purchase to unlock the premium features.

I did setup a chrooted SFTP user to receive the photos on the Linux machine.
Then configured this SFTP access in the app which worked seamless.
So far the manual sync of existing photos and videos worked reliably over WiFi.
And I'm looking forward for the geofence-triggered autosync to run 🤞🏻

In this article, MacKenzie builds up a config, script and systemd file to respectfully fetch an RSS feed with curl.

It uses the following as base config for curl:

fail
compressed
max-time = 30
no-progress-meter
alt-svc = alt-svc-cache.txt
etag-compare = tech.CitizenLab.rss.etag
etag-save = tech.CitizenLab.rss.etag
output = tech.CitizenLab.rss.xml
time-cond = "Tue, 05 Nov 2024 15:00:35 GMT"
write-out = "%output{tech.CitizenLab.rss.lm}%header{last-modified}"
url = "https://citizenlab.ca/feed/"
next

Then adds conditional checks for the etag-compare and time-cond directives, so they are only added if the corresponding file contains a non-empty value.

The last part is then to use a systemd Timer file with OnUnitInactiveSec=1hour, so that the command will be run one hour after the previous run finished.
