Beginnings of more flexible encoder and I/O support

However, the moteus hardware has always been capable of more, both because the processor is a very capable one, and the exposed IO pins are relatively flexible. While looking at some future designs that incorporate even more IO options, I decided it was time to update the firmware to finally start taking advantage of that flexibility.

My goals can be broken down into two parts. First, what types of IO (input/output) to support, and second, how those inputs and outputs can be used.

Hacker Diary: Embedded World 2022

Yesterday I went up to the Embedded World trade fair in Nuremburg, Germany. As a lone hacker, you often feel more than a little out of place when you buy chips in single unit quantities and the people you’re talking to are used to minimum order quantities of a million. But what’s heartening is how, once you ask an interesting question, even some of the suit-wearing types flip into full-on kids who like to explain the fun tech. I struck up conversations with more than a couple VPs of global chip behemoths, and they were cool.

3600 Games Now On The Steam Deck with Teardown, a Great Demolition Game as Verified

Valve has provided more verification in the past few days vs usual for the Steam Deck. We are now more than 3600 games validated (3626 games to be precise at the time of publication) on the Steam Deck – in two categories...

The Steam Deck’s Super Power: Super Sleep

The Steam Deck undeniably has some great features, but if it were a superhero its superpower might not be what you expect. No, it’s not the powerful processor or advanced options and software, but seemingly the complete opposite of that: the Steam Deck’s real power is its super sleep.

First, a superpower needs to be reliable and without any big caveats. The Deck’s sleep ability is just that: every time it works quickly and flawlessly. It is a quick power button press away or in the Steam button’s power menu. In the middle of a game without a pause button (hi, Elden Ring)? No problem. Running low on battery or just need a moment to move the Deck without accidentally hitting the buttons? Or want to resume in that spare minute to get in a quick gaming fix? The Deck delivers every time. You can also set the Deck to go to sleep after some idle time, confident you won’t lose your game progress or battery life.

[Slackware] Chromium 103 (regular and ungoogled) available as Slackware package

Apologies for the delay, I was out of town, but i have finally uploaded my new chromium 103 packages for Slackware 14.2 and newer. Their un-googled siblings are also available. Thanks as always to Eloston and his friends for updating the patch-set for ungoogled-chromium.
Last week saw a Google Chromium update which addresses a series of vulnerabilities, which is nothing new of course, but in particular one security hole that has now been patched would allow remote attackers to take control of your computer and execute arbitrary code. See CVE-2022-2156. An update of your installed browser package seems in order.

Learn C++ Programming Step by Step – A 20 Day Curriculum!

Although there are numerous programming languages available in the market to work upon, but C++ has never lost its charm since its inception and still has a strong impact in the development world. As per the reports, C++ comes under a few top programming languages across the world. Alike the C programming language, C++ also makes it easier for you to understand the underlying architecture of programming, although it also supports other additional features such as object-oriented programming, exception handling, etc. Moreover, various IT giants Google, Amazon, Microsoft, etc. offer numerous career opportunities to C++ professionals, hence you’re strongly recommended to give it a try and start to learn C++ Programming.

Security by Diversity: Designing Secure, Reliable and Robust Systems

This is the first in a series of blog posts on Security by Diversity. Here we'll focus on the scaling properties of reliability through diversity. Later blog posts will introduce the business and economic aspects of security through diversity and discuss not only technical security but also how to secure coordination and similar organisational aspects.

Firmware updates, part 2: Transporting the update

This is the second post in a series about doing device firmware updates (DFU) over the air (OTA) and continuous deployment of firmware for embedded devices. We'll explore the different parts of a complete end-to-end system with this capability.

This post will be about the different networks and how you can manage firmware updates using them.

A mystery with Fedora 36, fontconfig, and xterm (and urxvt)

As of Fedora 36, Fedora changed their default fonts from DejaVu to Noto. This changes what the standard names 'serif', 'sans', and especially 'monospace'. When I upgraded my desktops to Fedora 36, I had a very bad reaction to the 'monospace' change, because the result looks really bad. It turns out that part of the reason that the result looks bad (although not all of it) is specific to xterm, and that is where the mystery comes in.

App Rules Are Twisted to Absurdity

Apple and Google have twisted their decade-old rules for their app stores like a pretzel to the point where they may no longer make sense. This has made buying digital stuff in apps convoluted as heck.

One example: In theory, although not yet in reality, you can use your Amazon account to buy an e-book from Kindle’s iPhone app. You cannot buy an e-book in the Android version of the app. Until recently, Kindle purchases were effectively a no-go under Apple’s rules but fine under Google’s. Now it’s the opposite.

Confusing? Yep. Apple and Google have written long, complicated guidelines for apps and have frequently revised those rules to protect their own interests. (I’ve noted before that Apple’s app rules are much longer than the United States Constitution.)

Red Hat Learning Community celebrates 100,000 members

The Red Hat Learning Community (RHLC) celebrates a monumental milestone this week as it exceeds 100,000 members! At its launch in September of 2018, the main goal was simple: provide a collaborative space for open source learners to connect as they optimize their skills in working with Red Hat products. As the core of that mission has remained true since its launch, Red Hat has strived to provide our users what they need in order to collaborate, learn, build skills and meet their individual learning and career goals.

openSUSE Tumbleweed – Review of the week 2022/25

During this week, we sweat some blood. Not only was it really hot here, but we also had a gap in the snapshots delivered. Turned out that the update to SELinux 3.4 worked in most cases – but not so well with containers. We stopped rolling for a few days to figure out the fixes for that one issue before merging other, large changes. Nevertheless, we still delivered 6 snapshots this week (0616,0617, 0618, 0619, 0622, and 0623).

Startup crowdfunding high-refresh-rate e-paper monitors • The Register

E-paper display startup Modos wants to make laptops, but is starting out with a standalone high-refresh-rate monitor first.

The initial plan is for the "Modos Paper Monitor," which the company describes as: "An open-hardware standalone portable monitor made for reading and writing, especially for people who need to stare at the display for a long time."

The listed specifications sound good: a 13.3", 1600×1200 e-ink panel, with a DisplayPort 1.2 input, powered off MicroUSB because it only takes 1.5-2W.

The company also has some rather impressive demonstration videos, showing that the display is fast enough to play video, albeit in monochrome. There's also a technical explanation of how this is accomplished.

Annotated Perl::Critic Policy Index | Tom Wyant [blogs.perl.org]

In the wake of my postings on the file access tests (-r and friends) I wondered if there was a Perl::Critic policy to find them. So I constructed an annotated index of Perl Critic policies. Because of its size I stuck it on GitHub rather than in-line to this blog post.

This index assumes that any CPAN module whose name begins with Perl::Critic::Policy:: is a Perl Critic Policy. The index entry for each module contains the name of the module itself (linked to Meta::CPAN), the name of the distribution which contains it, and the abstract for the module if it contains anything other than a repeat of the module name. I suppose the module description could have been added, but I hoped the abstract would be sufficient.
