NERF - Trammell Hudson's Projects

The NERF project is a collaboration with Ron Minnich at Google (creator of LinuxBIOS and coreboot) that aims to build an open, customizable, and slightly more secure firmware for server machines based on using Linux and Heads in the ROM to replace UEFI as the bootloader. Unlike coreboot, NERF doesn't attempt to replace the chipset initialization co...
 

Backpack done! or is it?

My new backpack!

Immagine/foto

I started this project in august (pattern and material list) / september (actual sewing) and finally, this evening, it is usable!

It wasn't the only project running (not even the only *sewing* project), but still it took enough time that I'm glad I can finally use it, even if right now it doesn't really have any real advantage over what I could have bought from any store for less money than I spent on materials (but I have many leftovers — and plans to use at least part of them)

It also was pretty challenging, both for my skills and for my home sewing machine, and there are a few things that could have been done better (and maybe they will, in the next backpack I'll make?)

Immagine/foto

But is it really done? No, that webbing in the front (and sides) is there to attach extensions, and I have at least a couple planned (one easy, that I will do soon, and another complex one that will wait until I've recovered from the project fatigue with something completely different).

I'm also still waiting for the buckles that will close the compression straps in the front (not that they are really needed now that there are no extensions to keep compressed), but they are details I can take care of later.

P.S. I took pictures and notes, and the pattern is already on git, but a full tutorial will have to wait, probably even months, as now I have a bit of sewing backlog.

Dino in Debian experimental



What is Dino?



Dino is a modern IM client using XMPP (Jabber) with support for both OpenPGP and OMEMO. It looks very nice and can already be used for chatting and group conversations. It is, however, not yet stable nor feature-complete. If you are looking for something like Conversations (Android XMPP client), but for the desktop, Dino is for you. If you like to have something more stable and feature-complete, try Gajim instead. I use both! :~)





Dino is written in C and Vala, uses the GTK+ UI toolkit and looks best in Gnome, XFCE, or other GTK+ based desktops. I heard about planned versions for Windows and MacOS, too, but don't hold your breath.

How to install Dino on Debian?



Since yesterday, the Dino IM client is available in the official Debian repositories, but so far only in the "experimental" distribution. To install it, Debian users have to:
$ echo deb https://deb.debian.org/debian/ experimental main | sudo tee /etc/apt/sources.list.d/experimental.list
$ sudo apt update
$ sudo apt -t experimental install dino-im


This should work on nine official and five unofficial architectures for at least unstable and testing. Not sure about stable. I'm pretty sure, that oldstable will not work.

Why the "-im" suffix for Dino in Debian?



There used to be another program, an "integrated MIDI piano roll editor and sequencer engine", by the same name in Debian. Many references to the old program still exist, so it would be problematic to recycle the name for a different purpose.

Happy chatting!

Petter Reinholdtsen: Web services for writing academic LaTeX papers as a team

I was surprised today to learn that a friend in academia did not know there are easily available web services available for writing LaTeX documents as a team. I thought it was common knowledge, but to make sure at least my readers are aware of it, I would like to mention these useful services for writing LaTeX documents. Some of them even provide a...
 

Help! Linux ate my RAM!

But how do you count memory that is currently used for something, but can still be made available to applications? You might count that memory as "free" and/or "available". Linux instead counts it as "used", but also "available": This "something" is (roughly) what top and free calls "buffers" and "cached". Since your and Linux's terminology differs...
 

EtherDFS - The Ethernet DOS File System

EtherDFS is an 'installable filesystem' TSR for DOS. It maps a drive from a remote computer (typically Linux-based) to a local drive letter, using raw ethernet frames to communicate. For years, I was using LapLink to transfer files between my various "retro" computers. It works, yes, but it's also annoyingly slow and requires constant attention. On...

Programma Linux Day 2017
Il Linux Day è la principale manifestazione italiana dedicata alla promozione di GNU/Linux e del Software Libero; quest'anno si terrà il 28 ottobre in numerose città Italiane.

Il GL-Como e il LinuxVar organizzano quest'anno una edizione congiunta, presso il FaberLab di Tradate.

La giornata di quest'anno sarà divisa in due parti: il mattino dedicato specificatamente alle scuole e il pomeriggio destinato a professionisti, studenti e appassionati di informatica; entrambe sono accomunate dal tema nazionale: “privacy e riservatezza individuale”.

Il programma dettagliato e tutte le informazioni pratiche sono disponibili all'indirizzo http://linuxvar.it/content/linux-day-2017
 

Millions of high-security crypto keys crippled by newly discovered flaw

Factorization weakness lets attackers impersonate key holders and decrypt their data.
This includes ID cards, TPM and OpenPGP keys generated on a some card-like devices (e.g. yubikey) (as opposed to those generated on a computer, that are safe).

Navigation, ancients-style

The GPS on my firefoxOS phone has been acting up lately: it has never been exceptionally good, but the last couple of times I've tried to use it it gave errors of more than 1km.

Saturday evening we were in a place with internet (and laptops) and had to go to a new-to-us restaurants, so I asked for routing from OSMR, took notes on paper and this is what I gave to my navigator/co-driver:

Immagine/foto

Unbelievably we managed to get there in time, without missing even one of the turns, even if he wasn't able to decipher my writing on some of the street names.

Italian readers may also appreciate the maturity of some of the labelling, if they are able to decipher the writing.

Also, in case we decide to go back to that restaurant with the LUG, I guess I can just point them to this post and of course they will be able to get there, right? :D

One day I will have a GPS-enabled device that is not designed to steal my data first and be useful to me as an afterthought. And one that works.

Campingpunk

Immagine/foto

Today a friend of mine (meow if you want to be identified¹) mentioned that it would be nice to have a name like campingpunk for a look with less brass than steampunk and more anodized aluminum and paracord. Also a bit like crazy survivalists with less camo and more colors.

I like the idea.

¹ no, that doesn't uniquely identify them: I tend to have many friends with feline tendencies.

Tonight I dreamt of an old man, dressed in grey with a wide felt hat, who was tending a small vegetable garden like the ones typically kept by retired men.
He was using a tool that changed shape according to what he needed in that moment, but at every change it blinked a bit as if it wanted to return to its native shape of a spear.

Now I'm a bit worried for humanity's sake. :)

P.S. even more worryingly his usual associate wasn't around to be seen.

This is VENETO!

While having breakfast near Venice one of our group of friends noticed that the ingredients in the chocolate filling of his croissant included ethyl alcohol.

Immagine/foto

This isn't that strange, as it is commonly used as a preservative in such creams, although there is a bit of contrast with the labeling "prepared: with non-OGM ingredients without added preservatives nor colorings without hydrogenated oils".

Immagine/foto

A bit more unexpected was the fact that also the jam croissant included alcohol, as usually jams spoil less than chocolate creams.

Immagine/foto

Evidently there is one explanation that is simple, self-coherent, fun and unlikely: Venetian people being Venetian, and needing their bit of alcohol in the morning!

(In the picture above I've removed the name and address of the producer because this post is just me being silly, but I've left the province: TV)

Python FAQ: Why should I use Python 3?

Part of my Python FAQ, which is doomed to never be finished. The short answer is: because it’s the actively-developed version of the language, and you should use it for the same reason you’d use 2.7 instead of 2.6. If you’re here, I’m guessing that’s not enough. You need something to sweeten the deal. Well, friend, I have got a whole mess of sugar cubes just for you. And once you’re convinced, you may enjoy the companion article, how to port to Python 3! It also has some more details on the diffences between Python 2 and 3, whereas this article doesn’t focus too much on the features removed in Python 3.

improved slatts belt

In one of the comments (near the bottom) on http://tacticalintelligence.net/blog/slatts-rescue-belt.htm there was a suggestion to alternate the direction of the loops to prevent the paracord from twisting badly.

This is the process and the result:

(making a full belt with 20m of paracord took about a day of picking it up, doing a couple of rows while in front of the computer and putting it down again)
 

Instant gratification

In the last few days I spent my sewing time on a complex project that — of course — was having issues, so today I decided to take a break and go for instant gratification and a couple of quick project.

Immagine/foto

A ticket bag with magnets closure, to be worn on the same lanyard as a badge to prevent the issue of people being called "on site meals" .

This involved sewing tiny (~2mm ⌀) magnets on slipperynesssilicone coated fabric, because instant gratification is one thing, but making it too easy wouldn't be masochistic enough.

Immagine/foto

A simple drawstring backpack. I'm not completely happy about the ends of the drawstring channels, so when I make another one I may change them a bit.

Both are made in cheap, relatively light (90g/sqm) silnylon, and thus at least water resistant (I didn't seal the seams to make them completely waterproof).

I took pictures and notes, so full instructions will be posted on my website... sometime...

Qt 4 removal in Debian testing (Buster)/unstable

Bits from Debian - Blog from the Debian Project

Today, Saturday 12 August 2017, the annual Debian Developers and Contributors Conference came to a close. With over 405 people attending from all over the world, and 169 events including 89 talks, 61 discussion sessions or BoFs, 6 workshops and 13 other activities, DebConf17 has been hailed as a success.
All of the videos except for one have already been published, so if you weren't there nor watching the streamings you can now download and watch them...

and why not contribute to the subtitling effort (not yet set up, but do come on #debconf-video@OFTC and let the team know that you are interested in contributing).

PDP-8/e Replicated — Introduction

I am creating a replica of the DEC PDP-8/e architecture in an FPGA from schematics of the original hardware. So how did I end up with a project like this?
The story begins with me wanting to have a computer with one of those front panels that have many, many lights where you can really see, in real time, what the computer is doing while it is executing code. Not because I am nostalgic for a prior experience with any of those — I was born a bit too late for that and my first computer as a kid was a Commodore 64.
And then there is a follow up post: https://activelow.net/post/pdp8e-replicated-overview/
