The Sequencer: Detect one-dimensional sequences in complex datasets

The Sequencer reveals the main sequence in a dataset if one exists. To do so, it reorders objects within a set to produce the most elongated manifold describing their similarities which are measured in a multi-scale manner and using a collection of metrics. To be generic, it combines information from four different metrics: the Euclidean Distance, the Kullback-Leibler Divergence, the Monge-Wasserstein or Earth Mover Distance, and the Energy Distance. It considers different scales of the data by dividing each object in the input data into separate parts (chunks), and estimating pair-wise similarities between the chunks. It then aggregates the information in each of the chunks into a single estimator for each metric+scale.

What Will It Look Like When Betelgeuse Goes Supernova?

640 light years away, there is a colossal star that is on the verge of exploding in a magnificent supernova. But what will it look like from Earth?

To upload this video, I converted it and compressed it to less than a tenth of the original size under linux with the free software ffmpeg and the corresponding command:

'ffmpeg -i video_in.webm -vcodec libx265 -crf 40 video_out.mp4'

Maybe you would like to post a corresponding video on a scientifically related topic, but it is perhaps too big? Then try ffmpeg.

Often the compression factor '-crf 28' is enough, but in this particular case I had to go up to '-crf 40', because the original is a 4K UHD video and has a file size of 377MB. The compressed version here has a file size of only 28.4MB .
Of course, the quality of the video decreases, but it is enough to illustrate the topic.

Want to see the video in all its glory? Then visit the channel youtube.com/@V101SPACE and let Rob explain exciting space-related topics to you

Netencode: I’m currently building out my project of making a “better” structured language for use in UNIX-pipelines and shell scripting and the like.

It’s human-readable, but supports trivial generation with printf & wc, tagged values (sum types, Result<T>) and embedding arbitrary binaries without escaping due to being length-prefixed.

I think it’s pretty cool!

Yay! Or maybe AIEEE! Seems like I'm giving a talk at #EuroBSDCon again this year!

Anyone who has been following me here for a while will know I'm a hopeless #retrocomputing nerd, and I will make no attempt at hiding it during my talk:

Dirty Tricks: Using nginx and Lua to thwart bots and skript kiddies

I'll (try to) show how you can protect your #BBS from drive-by portscans and your production systems from #DDoS attacks using all the wrong tools.

Just updated (make buildworld) #FreeBSD Current (#main) 15.0. As always, everything went smoothly!

Just a quick note: on first boot, the laptop didn’t connect to Wi-Fi because the driver (iwlwifi module – man.freebsd.org/iwlwifi/4) was missing.
If you run into the same issue, just enable USB tethering on your smartphone, load urndis (man.freebsd.org/urndis/4), and simply run # fwget (man.freebsd.org/fwget/8).

Now time for a nice pkg upgrade -f to finish things up… and everything’s up to date!

Serious poll (comedy has left the room, real answers only please).

Are you or the entity you work for running an actual server-model #UNIX?
To clarify:
Not a Unix-like: Linux, BSD, Minix, etc.
Not a client-model like a laptop, or workstation, etc.)

#TIL in #unix's cron, setting the weekday doesn't mean "Run it on this day every month if it happens to land on a sunday", it actually means: "Run this on every sunday, or this day of the month"

Extremely satisfied with my ThinkPad T480 running on FreeBSD 14.3-RELEASE!

I got the machine used and upgraded it:
- 32 GB of memory
- 1 TB SATA SSD
- Innolux N140HCG-GQ2 FHD LCD panel
- New Lenovo backlight keyboard (US-ANSI)
- Glass Trackpad from X1 Carbon
- Intel AX210 WiFi module (802.11ax)
- Dual batteries

Literally everything in that laptop, that I need does work on FreeBSD 14.3:

- WiFi with 5Ghz and proper speeds
- Sleep/Resume
- Integrated Webcam
- Power management
- Trackpad
- Thunderbolt Docking (including Audio and HDMI)

It's the perfect development and productvity machine :freebsd:

My complete setup is currently as follows:

Linux Mint and FreeBSD on all my computers and notebooks
Pixel 9 with Graphene OS (but will be replaced by a new Fairphone 6 with /e/OS from Murena in the future)
Connected via KDE Connect
Office with LibreOffice
My own Nextcloud for files, photos, calendar and contacts
Hardened Firefox with uBlock Origin
Freetube and Newpipe instead of YouTube
Ecosia search instead of Google
Proton Mail and Tutanota Mail
Simple fitness tracker with watch, Pedometer, sleep tracker and calorie counter without Bluetooth and app connection instead of spying smartwatch and "health apps" such as Fitbit, Apple or Samsung Health
Manual recording of my health data such as blood pressure, blood sugar, sleep, steps and more in a LibreOffice Calc spreadsheet, can be easily converted into a PDF for my doctors to evaluate

Am I missing anything? Absolutely not! This setup works just as smoothly and conveniently as previous ecosystem solutions from Apple, Google or Samsung. Only with significantly more privacy, without tracking and surveillance by US Big Tech

Instead of standardizing one templating syntax (that'll be bikeshedded to death), give us the primitive: fast DOM access from any language. Let a thousand templating libraries bloom - in any language. Lower-level primitives enable more innovation than high-level APIs. That's the Unix philosophy. Simple, composable, powerful. Build the foundation right. #compsci #webdev #wasm #frontend #unix

🖥️ My ultra-budget server powering websysctl.alfonsosiciliano.net has been running smoothly for the past 2 months. So far, so good!

📈 #Crawlers hit tens of thousands of sysctl parameter pages daily. That's fine, since robots.txt allows it. But why keep requesting non-existent pages as if the site were built with WordPress 😤 ? Fortunately, the stack (#FreeBSD :freebsd: + #OpenResty 🌐 + #Lapis ✏️ + a custom-built #database 📦 ) stays well within the limited resources of my $5/month cloud server.

The code might soon be #OpenSource stay tuned!
