After a prolonged period of inactivity, new devs have taken over to support
htop. The new 3.0 release features lots of improvements (

underlying low-level items.
Since 2012, the Raspberry Pi nano computer has become an increasingly important part of the DIY and « maker » community. The increase in power of the Raspberry Pi over the years offers very interesting possibilities for radio amateurs. Indeed, it allows not to permanently monopolize a PC in the decoding of frames with software like WSJT-X, FLDIGI, etc…, without forgetting the possibility to control the Raspberry Pi remotely and thus to be able to work outside the radio shack as I can sometimes do on my couch. Moreover, this nano computer is now widely used in any Hotspot (DMR or D-STAR).
Researchers from Intel Labs have developed an open-source 3D printed smart robot that it is possible to build for less than $50.
Once combined with a modern smartphone, the additive bot is able to navigate autonomously, and its real-time sensing capabilities enable it to conduct recon tasks such as following people. The PLA-based Openbot has also been designed to be easy to build too, and its STL files have been made freely available online. By making their design public, the researchers hope that creators will tinker with and improve their robot to continue developing new applications for it in the future.
In the 8-bit age, data screeched slowly off tape decks. In the 16-bit era, floppy drives whirred, clinked and chunked according to the peculiarities of the system's disk controller. For the BBC's "Boring Talks"—podcasts about things most people would find boring—journalist Keith Stuart remembers.
YARH.IO is a fully hackable and custamizable Raspberry Pi based handheld, running Raspberry Pi OS and supporting all other Operating Systems available for Raspberry Pi.
On this page, I want to share and document my experiences flying and using a kite antenna. There's nothing too special about a kite antenna. It's a fun, novel approach to the ham's age-old question about where to hang a wire antenna. When I lived inland, I could usually find a tall tree in which to hang an antenna. After relocating to the Galvston Island, tall trees are hard to come by. While the beach may lack trees, it usually does not lack wind.
A kite antenna setup is pretty straight forward and once you deploy it a couple times, it's downright simple. The key factor is having enough wind!
Neugierig wurde ich durch eine Veröffentlichung von W9SCH in der SPRAT Nr.69 unter 'A Four-Band UP & OUTER Antenna' und später durch einen Artikel im QRP-Report. Die Antenne ist als 'Upper & Outer' bekannt geworden. Sie besteht lediglich aus einem vertikale Strahler, dünner Draht, der locker um einen Glasfiebermast gewickelt wird und einem horizontalen 'elevated' Radial. Dieses Radial, als 'zweiter Strahler' bildet das einzige Gegengewicht, keine weitere Erdung. 'Wenn Strahler und Radial die gleiche Länge, λ/4 haben, funktioniert die Antenne schon recht brauchbar. Ein Tuner sollte aber eingeschleift werden, um das SWR zu optimieren.
Amateur radio (Ham radio) operators and engineers, have been experimenting with radio and antennas since Marconi. The use of a kite to support an antenna makes for great days operating and a wonderful HF antenna.
The linked pages that are listed below describe
various elements of a typical kite-antenna flying
field setup. One important lesson that we have
learned so far is that good kite-antenna contacts
result from flying the best possible antennas.
Another lesson learned is to keep the time that is
required to set up and put away as short and
convenient as possible - otherwise we will not do it!
Admittedly, we already have a page about our kite antenna exploits which makes for interesting reading. However those pages are about the practical use of these antennas. This talk given by Henryk M0HTB covers some of the background and the equipment considerations to supplement the practical exploits.
Sie finden hier zahlreiche Kartonmodelle zum Ausschneiden und Zusammenkleben, z.B. Burgen, Gebäude und technische Modelle.
Der 1831 gegründete Verlag J.F. Schreiber brachte bereits ab 1878 Kartonmodelle heraus. Seit 1998 wird das Programm der Schreiber-Bogen vom Aue-Verlag in Möckmühl weitergeführt.
- Inhaltszusammenfassung
Das Vorhaben umfasst hauptsächlich folgende Maßnahme(n):
-
sicherheitstechnisch gleichwertige Umsetzung für die vereinfachte smartphone-basierte Verwendung des E-ID
-
Zulässigkeit der Verwendung von Attributen aus dem Identitätsdokumentenregister sowie aus Registern von Verantwortlichen des privaten Bereichs über das System des E-ID und Bereitstellung dieser Daten an Dritte
- Kurze Begründung
Es sollen die technischen Weiterentwicklungen in Hinblick auf eine vereinfachte smartphone-basierte Verwendung des E-ID Berücksichtigung finden, um eine einfache, userfreundliche Nutzung des E-ID auf einem Smartphone zu erreichen.
Weiters soll durch die geplanten Maßnahmen die Datenqualität und Ausweitung der Nutzungsmöglichkeiten des E-ID gesteigert werden.

eDEX-UI is an open-source cross-platform terminal emulator that presents you with a Sci-Fi inspired look along with useful some features as well.
It was originally inspired from the DEX UI project. It is also worth noting that eDEX-UI is no longer maintained but it hasn’t been completely abandoned. You can learn more about the current status of the project here.
Even though eDEX-UI is more about the looks and the futuristic theme for a terminal, it could double up as a system monitoring tool for Linux in the future if the development resumes or if someone else forks it. How? Because it shows system stats in the sidebar while you work in the terminal.

Wer seinen PC in eine PDP-11 von DEC mit der UNIX Time-Sharing System Seventh Edition (V7) als Betriebssystem verwandeln möchte, der kann den Sanos-Port von Bob Supnik’s PDP-11 simulator ausprobieren. Denn mit Diesem ist es möglich, UNIX so auszuführen, wie es Dennis Ritchie und Ken Thompson im Jahr 1979 getan haben.
Ein Sanos-Entwickler hat ein ISO-Image mit Sanos, dem PDP-11-Simulator und dem UNIX V7-Kit vom Computer History Simulation Project erstellt. Einfach eine CD-ROM in den PC einlegen und starten. Danach wird für alle nostalgischen UNIX-Geeks der PC zu einer PDP-11 mit dem UNIX V7.
Have you ever wanted a theme tune to play as you enter the room? Perhaps the imperial march, a pop hit or Super Mario’s Jolly Roger Bay. Well now you can thanks to the Human presence triggered music player – a small box which will wait for your arrival and serenade you when you step in trough the door and switch the lights on!
It’s designed for service rooms but has applications for all kinds of locations and establishments. The music is stored on an SD card, which can be selected by pressing the knob – which also controls the volume when turned. You might like to have some relaxing music to accompany a deep bath or something to get you pumped up for the home gym – whatever you choose it’s an unusual and ingenious device. Simply let it play out or turn off the lights to stop the music!

Topics covered will include the user/kernel interface, fundamental concepts of Unix, user authentication, basic and advanced I/O, fileystems, signals, process relationships, and interprocess communication. Fundamental concepts of software development and maintenance on Unix systems (development and debugging tools such as "make" and "gdb") will also be covered.
Students are expected to have a good working knowledge of the C programming language, have written non-trivial programs before, and to be able to competently use a Unix system with a command-line shell interface. All coursework will be done exclusively on a Unix system from the command-line. This is not an introduction to using Unix!
