ESP32 board with 150Mbps 4G LTE modem also supports RS485, CAN Bus, and relay expansion - CNX Software
LILYGO has designed another ESP32 board with a 4G LTE modem with the LILYGO T-A7608E-H & T-A7608SA-H variants equipped with respectively SIMCom A7608SA-H for South America, New Zealand, and Australia, and SIMCom A7608E-H for the EMEA, South Korean, and Thai markets, both delivering up to 150 Mbps download and 50 Mbps upload speeds.
The board also supports GPS, includes a 18650 battery holder, and features I/O expansion headers that support an add-on board with RS485 and CAN bus interfaces, in a way similar to the company’s earlier TTGO T-CAN485 board with ESP32, but no cellular connectivity.

FSFE Information stand at Veganmania MQ
Submitted by Roy Schestowitz on Sunday 26th of June 2022 08:14:48 PM Filed underFrom 3rd to 6th June 2022 happened the Veganmania street festival at the Museumsquartier in Vienna. Despite not happening for two years due to the Corona pandemic this over the years has developed into the biggest vegan street event in Europe with tens of thousands visitors everey day. Of course there have been plenty of food stands with all kinds of climate and animal friendly delicious meals but the festival had also many stands for buying other stuff. In addition many NGO tents were there too to inform about important issues and their work.
Like already tradition for many years also the local volunteers group manned an FSFE information stand from Friday noon until Monday night. It was exhausting because only two volunteers manned the stand. But we both stayed there the whole time and the interest of so many people had confirmed once more how well we optimized our information material assortment without losing the ability to bring everything at once using just a bicycle.
The front of our stall was covered with a big FSFE banner while the sides are used for posters explaining the four freedoms and GnuPG email encryption. (We very soon need to replace our old posters with more durable water resistant paper since the old one has gotten rather worn down and doesn’t look very sleek any more with all the tape pieces it is hold together.) In addition we use a small poster stand we built ourselves with just two wooden plates and a hinge. This was of left over material from a DIY center. Unfortunately this time we didn’t have any wall behind us where we would have been allowed to put any posters or banners on.

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.

Microsoft Receives Backlash Over Minecraft Moderation Changes
Ever since Minecraft's release, fans have set up servers to allow for multiplayer in the game. However, a recent update is causing concern among server moderators and players alike, as Microsoft is moving to implement its own moderation on top of the already-existing tools provided to server owners.
For several years now, Minecraft has been split into two versions. The Java Edition allows for more freedom with modding and server hosting, while the Bedrock edition allows cross-platform multiplayer, implements microtransactions, and gives its server owners less freedom.

‘3.5 million cyber security jobs will open up by 2025’ [Ed/iophk: their approach to "security" is job security (for them alone) and not actual computer security]
Pointing out how the world is facing a major workforce shortage in the cybersecurity sector, Kate Behncken, vice- president and global head of Microsoft Philanthropies, on Friday, said that there would be 3.5 million open roles in cyber security around the world by 2025.
Speaking at the launch of CyberShikshaa initiative, launched by Microsoft India in collaboration with ICT Academy as part of its ongoing commitment to create a robust cybersecurity ecosystem in the country, Behncken said, “The number of cyber security incidents in India have increased from 2.9 lakh in 2018 to almost 1.5 million in 2021.

After years of delay, Plex replaces its desktop media player client
Mediaphiles have had years to cope with the imminent demise of the Plex Media Player. Plans were first announced in August of 2019, right when the Plex had also released its intended replacement, the Home Theater PC app. Outrage from the crowd stopped everything in its tracks for three years, but at last, Plex is now calling time of death for PMP. Long live HTPC.

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. -

Free RPG Day: Create maps for your Dungeons & Dragons game with Mipui | Opensource.com
It's Free RPG Day again, and there's no better to play a free roleplaying game than with free and open source software. In this digital era of pen-and-paper gaming, it's still relatively unusual for adventures to include digital maps. In fact, it's also unusual for paper adventures to include maps that are sized correctly for miniatures, and many that do have colourful and richly textured maps that look great in a glossy book but look murky when photocopied and enlarged for the tabletop. Long story short: a tabletop gamer is often in need of a quick and convenient way to produce maps. Mipui is an open source web app that enables you to create grid-based maps for role-playing games, and it works great for virtual and physical tabletops alike.

Hackaday Podcast 174: Breaking Into The Nest, The Cheapest 3D Printer, A Spy In Your HDMI, And AI All Over The Place
Fresh from vacation, Editor-in-Chief Elliot Williams makes his triumphant return to the Hackaday Podcast! He’s joined this week by Managing Editor Tom Nardi, who’s just happy he didn’t have to do the whole thing by himself again. In this episode we’ll talk about tackling BGA components in your custom PCBs, a particularly well executed hack against Google’s Nest Hub, and why you probably don’t really want the world’s cheapest 3D printer. We’ll also take a look at an incredible project to turn the Nokia 1680 into a Linux-powered handheld computer, a first of its kind HDMI firewall, and a robot that’s pretty good at making tacos. Listeners who are into artificial intelligence will be in for quite a treat as well, as is anyone who dreams of elevating the lowly automotive alternator to a more prominent position in the hacker world.

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.

Signing email with DKIM is becoming increasing mandatory in practice
There are people who don't like email forwarding, but I can assure them that it definitely happens, possibly still a lot. Unless you want your email not to be accepted by GMail when forwarded, this means you need to DKIM sign it, because forwarded email won't pass SPF (and no, the world won't implement SRS).

Weave Cybersecurity into your product design
How important security is for your application and digital services? “Very important”, this is the answer we get the most often from Product Managers and Executives. Nobody wants the malware to take advantage of the vulnerabilities of their applications. However, any access point to the internet can be an entry point for hackers. Considering the ubiquitous awareness of the importance and risks associated with security, you may expect that security has been well embedded in all the aspects of digital product development, especially in the early stages of product design when costs are comparatively manageable.
Unfortunately, according to a recent study by MIT, “cybersecurity is rarely considered among the criteria in the early design phase”. This study finds three reasons why this ignorance of cyber security happens in the early stages:

Comparing YottaDB Web Framework Performance
It is interesting to compare the performance of different web stacks and frameworks under simulated stress. To compare apples-to-apples, the database, the JSON string response to a REST query, and front-end load generator were the same.
Of course, this end-to-end test only involves a single operation. Any real application consists of many operations at different layers in the framework, only a fraction of which are database accesses.

The software operator design pattern: advantages – part 4 | Ubuntu
The software operator is a design pattern. Its design is based on successful applications where this approach was found useful. In other words, it’s a proven approach that can be recommended to others. But like all approaches, it’s important to understand their advantages disadvantages. Software developers need to understand when the application of this pattern leads to a good solution and – perhaps more importantly – when it does not.
[...]
Installing a single application locally is straightforward in most cases. There are app stores and package managers for that. However, installing applications on remote servers is a more tedious task, which becomes more complicated as the number of applications increases. First of all, the login to these machines must be prepared and maintained. But manually maintaining logins does not scale very well. In fact, what is desired is an entity that controls the required provisioning of the machine and performs the required steps. The software operator design pattern, as a dedicated entity, can cover the execution of operational tasks and the remote login, at the same time.

systemd-oomd issues on desktop
I have opened an upstream PR to implement this [1], and it seems upstream is OK with the idea in principle, but some more thinking needs to be done before it can be merged. Assuming we can push that change through upstream, service units will immediately benefit because .service files can configure the ManagedOOMPreference property. However, applications which are launched by gnome-shell or snapd run as transient scope units, which means the ManagedOOMPreference property needs to be set when e.g. systemd-run is invoked, as demonstrated in the example above. This means that a bit of integration work will be needed from snapd, gnome-shell, etc. to set ManagedOOMPreference=avoid on _some_ applications. This immediately raises new questions: 1. Which services and applications should be given a setting of ManagedOOMPreference=avoid by default? 2. What is the interface to designate such applications? It seems to me that we would want to have a "single source of truth" from which gnome-shell, snapd, etc. can determine when ManagedOOMPreference=avoid should be set.
