Tiny, stackable, Linux-based IoT module hits Kickstarter

Filed under
Linux

On Kickstarter, Onion launched a tiny, Linux-based “Omega” IoT module, along with a dock, stackable expansion modules, a cloud service, and web app tools.

Onion’s Omega joins a growing number of single board computers and computer-on-modules for Internet of Things applications that have tapped Qualcomm’s MIPS-based, WiFi-enabled Atheros AR9331 system-on-chip. For a pledge of $25, Onion’s Kickstarter campaign offers the Omega computer-on-module combined with a “dock” that turns it into an sandwich-style single board computer.

Development activity in LibreOffice and OpenOffice

Filed under
LibO
OOo

The LibreOffice project was announced with great fanfare in September 2010. Nearly one year later, the OpenOffice.org project (from which LibreOffice was forked) was cut loose from Oracle and found a new home as an Apache project. It is fair to say that the rivalry between the two projects in the time since then has been strong. Predictions that one project or the other would fail have not been borne out, but that does not mean that the two projects are equally successful. A look at the two projects' development communities reveals some interesting differences.

Jessie Release Date: 2015-04-25

Filed under
Debian

We now have a target release date of Saturday the 25th of April. We
have checked with core teams, and this seems to be acceptable for
everyone. This means we are able to begin the final preparations for
a release of Debian 8 - "Jessie".

The intention is only to lift the date if something really critical
pops up that is not possible to handle as an errata, or if we end up
technically unable to release that weekend.

Please keep in mind that we intend to have a quiet period from
Saturday the 18th of April. Bug fixes must be *in Jessie* before
then.

5 questions to determine if open source is a good fit for a software project

Filed under
OSS

A benefit of open source in general, and commercial open source in particular, is that you have the support of others as well as the ability to do the maintenance yourself.

I hope these questions will help you determine whether open source is a good fit for your next software project. Let me know if there are other questions you would add to this list.

OSS

My team has become very fond of an open source tool called Browserify. It was originally designed to allow the Node.js modules to be used in the browser, but we’ve leveraged it as the primary component in our build process. Over the last year, it has helped us to turn our monolithic code into a set of independent, maintainable modules. Previously, we were concatenating a big file and maintaining subsystem independence using namespaces, so this has been a big change for us.

  • reversing an openbsd kernel syspatch

    OpenBSD has provided binary patches for a select few architectures for a while now, to save users from the daunting task of running make on their own. Alas, this means you might now apply a patch without first reviewing it. In the olden times, you had a source patch, so obviously you meticulously studied every line before application, just like you advised new users on IRC to do. But now, who will believe you do this when the binary syspatch is right there, so easy, so tempting.

  • [GSoC 2022] Ham: A Jam Replacement

    Haiku currently uses a fork of Perforce Jam as its build system. While Jam is a great build system, its legacy codebase makes it difficult to fix bugs or introduce new features.

    Ham is a complete Jam rewrite that was started by Ingo Weinhold, but wasn’t completed. This project starts where Ingo left off to bring Ham to where it can be used as Haiku’s official build system. The new repository can be found here.

  • Daily logging on al-Toril

    What I’m gonna add in is a cheapo A5 notebook. The notebook is a daily log (and by daily, I mean days on al-Toril in the year 1494) that’s strictly for post-hoc. Keeping track of torches & shoes, but also take note of what happens (gonna make writing session reports a li’l easier). A symbol to capture extra-diegetical (real-life) todo-items for me (a square box probably), for example “remember to make a new crafting table for potions” or whatever (sort of like a bujo), and another symbol (maybe just underline) for references to the A7 & A4 loose sheets. So that non-post-hoc, actual prep prep can live there. Things that are actual stuff, forward references, will become cards instead.

    This is also great because I can use shorthand in the daily log (I need to use longhand for prep so that the players can verify stuff, but logs aren’t prep).

  • 8 reasons to ditch Chrome and switch to Firefox

    One such option is Firefox. It’s a rare browser not based on Chromium, the project that powers Chrome, unlike other rivals like Edge or Opera. It’s also backed by a team with a long, storied history in browser development and a deep interest in online privacy. As a result, using Firefox can boost your PC’s performance, better protect you on the web, and also make life more convenient, too. You’ll find it offers built-in features that don’t exist in Chrome or otherwise require third-party add-ons.

    Just like we’ve recently done with Vivaldi, the enthusiast’s browser, we’ve highlighted the top 8 reasons to quit Chrome and make the switch to Firefox. Let’s dig in.

  • OpenPGP Email Summit

    During the trip I suddenly remembered that Swiss was not part of the EU, so the roaming rules that apply to all EU countries and that allow EU citizens to use mobile internet and telephony abroad while not having to worry about astronomical bills from their provider would not count. I quickly did some research on how bad it would be. 7cts/10KB. What. The. Fuck. I quickly disabled roaming and mobile internet. Guess I’ll be dependent on the availability of Wifi for the next days. [...] After quickly refreshing, I took the bus to the other end of Geneva to the offices of Proton (formerly Protonmail). They hosted the 6. OpenPGP Email Summit which I was going to attend. When I got to the building, I had to call the office upstairs and one member of the Proton team came down to fetch me. On Thursday we only had an informal meeting of participants that already arrived. The real discussions would take place on Friday and Saturday, although when I entered the office room people already had discussions going. After the meeting we went to a small bar to get some drinks and a small dinner. This being my first OpenPGP meetup (apart from the Sequoia meeting I was invited to some time ago), it was nice getting to know many of the people I already knew from the internet in person.

  • Using Homebrew on M1 Mac

    If you’re coming to M1 Mac fresh, without any old projects or profiles, you probably won’t notice; Homebrew will work as it always has. But if you’re trying to migrate from an Intel Mac you won’t be able to just move packages that were once in /usr/local over to /opt/homebrew. No need to worry though, reinstalling everything on M1 is easy, it just may take a bit of time.

  • A backup is only as good as ...

  • Multiple level filters in jq

    Here's another note-to-self on using jq to shape JSON representations of OData to match what's returned using system query options. Thsi time it's all filtering at two levels.

    In the Back to basics: OData - the Open Data Protocol - Part 3 - System query options live stream last Friday we looked at OData's system query options.

    There was a question at the end about whether it was possible to use the $filter system query option at multiple levels, in an $expand context. I wrote up the question, and a detailed answer (summary: yes) with an example here: Can $filter be applied at multiple levels in an expand?.

  • 0024: HYTRADBOI postmortem, HYTWACFI?, preimp, emergent ventures, data and reality, merkle search trees, readyset, julia compilation times

    Now that all that HYTRADBOI craziness is over I'm focusing on preimp. The goal is to work towards the programming experience that I envisioned for imp, but hack it together in clojure to avoid getting bottlenecked forever on language design.

    So far I have a simple clojure notebook with coarse-grained incremental maintenance. There are data cells that can be mutated by other code, with the changes being persisted back into the cell. The notebook is backed by a simple crdt, so once I finish hooking it up to the server it will allow collaborative editing of code and data. Next step after that is rendering the output values as interactive widgets, and then adding bidirectional editing so that interacting with the widgets for derived views can push changes to upstream data.

  • Parsing JSON faster with Intel AVX-512

    A few years ago, we released a really fast C++ JSON parser called simdjson. It is somewhat unique as a parser in the fact that it relies critically on SIMD instructions. On several metrics, it was and still is the fastest JSON parser though other interesting competitors have emerged.

    Initially, I had written a quick and dirty AVX-512 kernel for simdjson. We never merged it and after a time, I just deleted it. I then forgot about it.

  • AI Attempts Converting Python Code To C++

    [Alexander] created codex_py2cpp as a way of experimenting with Codex, an AI intended to translate natural language into code. [Alexander] had slightly different ideas, however, and created codex_py2cpp as a way to play with the idea of automagically converting Python into C++. It’s not really intended to create robust code conversions, but as far as experiments go, it’s pretty neat.
