A tasty, self-hostable Git server for the command line. 🍦

Das Problem lag in den Weiterleitungsregeln des HTTP-Servers. Hier war "/Verse" als Startseite mit einem großgeschriebenen Anfangsbuchstaben definiert, was dazu führte, dass die HTTP-Weiterleitung nicht ordnungsgemäß funktionierte. Nachdem dies korrigiert wurde und "/verse" als Startseite festgelegt wurde, funktionierte die HTTP-Weiterleitung einwandfrei, und somit war das ACME-Protokoll auf den jeweiligen Domino-Servern einsatzbereit.

Right now, I want to talk about the heritage of these input/output mechanisms. Why is it that punched paper tape and the teleprinter were the most obvious way to interact with the first electronic computers? As you might suspect, the arrangement was one of convenience. Paper tape punches and readers were already being manufactured, as were teleprinters. They were both used for communications.

The tools I used and will describe are:

VPS – in this case, I used a basic Hetzner Cloud VPS, but any provider that provides IPv6 connectivity will do – if you want IPv6, of course.
FreeBSD – a versatile, stable, and secure operating system.
Wireguard – lightweight, secure, and at the same time, not very “chatty,” so it is also gentle on mobile device batteries. When there is no traffic, it simply does not transmit/receive anything. Well supported by all major desktop and server operating systems as well as Android and iOS devices.
Unbound – can make DNS queries directly to root servers, not through forwarders. It also allows you to insert block-lists and have a result similar to that of Pi-Hole (i.e., ad-blocking).
SpamHaus lists – to immediately stop connections to and from users on blacklists.

Wer in letzter Zeit auf einer Demonstration in Wien war, hat sie vermutlich bemerkt: Die Polizei setzt Drohnen ein, um Teilnehmer*innen vom Himmel aus zu beobachten. Aktuell baut das Innenministerium die Drohnenüberwachung aus. Dafür legte es sich ein „IMSI-Catcher-System zur Verwendung mit Drohnen“ zu.

Mit dieser Anschaffung wird eine neue Ära der Überwachung eingeläutet. Die Kombination aus Drohnen und IMSI-Catcher ermöglicht es, Personen unbemerkt zu überwachen oder Teilnehmer*innen von Versammlungen zu identifizieren.

I experienced the disconnect between the torture I was comfortable with and the torture that drove me away during my first year in college. As I've mentioned here a few times, most recently in my post on Niklaus Wirth, from an early age I had wanted to become an architect (the kind who design houses and other buildings, not software). I spent years reading about architecture and learning about the profession. I even took two drafting courses in high school, including one in which we designed a house and did a full set of plans, with cross-sections of walls and eaves.

Then I got to college and found two things. One, I still liked architecture in the same way as I always had. Two, I most assuredly did not enjoy the kind of grunt work that architecture students had to do, nor did I relish the torture that came with not seeing a path to a solution for a thorny design problem.

That was so different from the feeling I had writing BASIC programs. I would gladly bang my head on the wall for hours to get the tiniest detail just the way I wanted it, either in the code or in the output. When the torture ended, the resulting program made all the pain worth it. Then I'd tackle a new problem, and it started again.

Xapian is a highly adaptable toolkit which allows developers to easily add advanced indexing and search facilities to their own applications. It has built-in support for several families of weighting models and also supports a rich set of boolean query operators.

If you're after a packaged search engine for your website, you should take a look at Omega: an application we supply built upon Xapian. Unlike most other website search solutions, Xapian's versatility allows you to extend Omega to meet your needs as they grow.

In December 2023, Voyager started sending back gibberish instead of data. A software glitch, though perhaps caused by an underlying hardware problem; a cosmic ray strike, or a side effect of the low temperatures, or just aging equipment randomly causing some bits to flip.

The problem was, the gibberish was coming from the flight direction software — the operating system, as it were. And no copy of that operating system remained in existence on Earth.

Kunden des kommunalen IT-Dienstleisters Südwestfalen IT (SIT) brauchen momentan Nerven. Chaos ist seit November 2023 "das neue Normal". Die Südwestfalen IT leidet unter massivem Personal-Schwund, und nun kam zum Wochenende die nächste Hiobsbotschaft. Wegen Schwachstellen waren viele Verwaltungen in Nordrhein-Westfalen seit Freitag nicht per Mail erreichbar.

This book is for college students who are serious about being successful in study, and teachers who want to know how best to help their students learn.

Being a successful student is far more about being a smart user of effective strategies than about being 'smart'. Research has shown it is possible to predict how well a student will do simply on the basis of their use of study strategies.

This workbook looks at the most important group of study strategies – how to take notes (with advice on how to read a textbook and how to prepare for a lecture). You’ll be shown how to:

When Niklas Luhmann, the German sociologist, became professor, he was asked about his research project. His famous answer:

"My project: theory of society. Duration: 30 years. Costs: zero."

Twenty-nine and a half years later, he published the last chapter of what is probably the most systematic and comprehensive sociological theory ever written. In these 29 and a half years, he published roughly another 60 books and hundreds of articles on a huge variety of subjects. And all of it was achieved by writing one smart note at a time.

Think about how you take notes during class. Do you use a specific system? Do you feel that system is working for you? What could be improved? How might taking notes during a lecture, section, or seminar be different online versus in the classroom?

Adjust how you take notes during synchronous vs. asynchronous learning (slightly).

It is time for me to re-do my old thread about the origins of "80 columns" and how it can very well be related to pretty ancient stuff, not dissimilar to "space shuttle and horse's rear end".

As you know, the default mode on IBM PCs is text 80x25. The limitation of 80 columns per line, also known as "80 column rule" is still widespread; for example, that's the rule for Linux kernel. But why 80? Why not 70 or 90?

The answer to that is usually "IBM punch cards are 80 characters wide", but things are more interesting than that!

First, the commonly accepted column width was supposed to be 72. American typewriters used to have just 72 columns, earlier DEC terminals supported only 72 columns, and even IBM punch cards had only 72 columns for text.

Second, yes, IBM punch cards were 80 characters wide, but why?

Fasd (pronounced similar to "fast") is a command-line productivity booster. Fasd offers quick access to files and directories for POSIX shells. It is inspired by tools like autojump, z and v. Fasd keeps track of files and directories you have accessed, so that you can quickly reference them in the command line.

The name fasd comes from the default suggested aliases f(files), a(files/directories), s(show/search/select), d(directories).

Fasd ranks files and directories by "frecency," that is, by both "frequency" and "recency." The term "frecency" was first coined by Mozilla and used in Firefox (link).

GNU Stow is a symlink farm manager which takes distinct packages of software and/or data located in separate directories on the filesystem, and makes them appear to be installed in the same place. For example, /usr/local/bin could contain symlinks to files within /usr/local/stow/emacs/bin, /usr/local/stow/perl/bin etc., and likewise recursively for any other subdirectories such as .../share, .../man, and so on.

This is particularly useful for keeping track of system-wide and per-user installations of software built from source, but can also facilitate a more controlled approach to management of configuration files in the user's home directory, especially when coupled with version control systems.

Stow is implemented as a combination of a Perl script providing a CLI interface, and a backend Perl module which does most of the work. Stow is Free Software, licensed under the GNU General Public License.

zoxide is a smarter cd command, inspired by z and autojump.

It remembers which directories you use most frequently, so you can "jump" to them in just a few keystrokes.
zoxide works on all major shells.

Die NZZ wurde im vergangenen Frühjahr Opfer eines solchen Angriffs und hat sich dazu entschieden, die Hintergründe publik zu machen. Dass die meisten angegriffenen Unternehmen schweigen, spielt den Erpressern in die Hände. Ein Angriff gilt als Versagen. Dabei kann es jeden treffen. Die NZZ ist überzeugt, dass die Lehren aus dem eigenen Cyberangriff anderen Firmen helfen können, sich vor Ransomware-Banden zu schützen.

... he asked for a ladder, climbed up the generator and made a chalk mark on its side. Then he told Ford’s skeptical engineers to remove a plate at the mark and replace sixteen windings from the field coil. They did, and the generator performed to perfection.

Henry Ford was thrilled until he got an invoice from General Electric in the amount of $10,000. Ford acknowledged Steinmetz’s success but balked at the figure. He asked for an itemized bill.

Steinmetz, Scott wrote, responded personally to Ford’s request with the following:

• Making chalk mark on generator $1.
• Knowing where to make mark $9,999.

Ford paid the bill.

For decades, robots.txt governed the behavior of web crawlers. But as unscrupulous AI companies seek out more and more data, the basic social contract of the web is falling apart.
