$1 PinePhone pogo pin breakout board lets you connect add-ons without removing the back cover

Filed under
GNU
Linux
Gadgets

There are a lot of things that make the PinePhone different than most smartphones. It’s designed to run GNU/Linux-based operating systems. It has physical switches that can disable the camera, mic, and wireless features. And it has a set of pogo pins that make it possible to connect add-ons like a keyboard, fingerprint reader, or thermal camera to extend the functionality of the phone

The only problem is that you have to pop off the back cover to access those pogo pins, so many of the official and unofficial PinePhone mods that take advantage of the pins are designed to either replace the cover with a new one or cut a hole in the existing cover.

Lenovo IdeaPad 3 - Windows and Linux experience a week later

Filed under
Gadgets

Here we are. My initial satisfaction with the laptop's default offering has gone down some. I am quite disappointed with how Microsoft chooses to promote Windows 10. Yes, it rules the desktop market, so it can do pretty much what it pleases, but this is a long game. And in the long game, they are not winning themselves any loyalty. If Linux ever achieves functionality parity, off I go. The same goes for Lenovo. I don't mind a vendor offering its tools and solutions. That's fine. But if I choose to have those tools removed, then there are no two ways about it. I'm most likely not going to buy any Lenovo machine again, because I don't appreciate being treated like a potato.

In this regard, Linux does a much friendlier job - to be let down by random erraticism. I'm talking about the sound config I had to handle, plus the VLC quirk. And let's not forget Secure Boot - even though it does not affect my two installed distros at the moment. Hardware wise, the keyboard quirks are quite annoying, and the screen can do only so much. Other than that, the laptop is robust and neat, fast, and the CPU fans don't rev too much. The battery life is pretty good, but I need more data to verify if the original numbers hold true.

Well, there you go. This is my satisfaction report a week into the laptop's usage. I am certain there will be more lovely surprises, twists and turns along the way, but then, part of the experience is figuring out issues early. This way, if and when I deploy software in my production setup, I will have all the right workarounds in place, and my seven-digit IQ will not be affected. Stay tuned for more good stuff. See ya.

Crowdfunding Astro Slide 5G smartphone ships in June, has a physical keyboard, and promises Linux support

Filed under
Gadgets

The Astro Slide is a 5G smartphone with a 6.5 inch display and a physical keyboard that slides out from behind the screen, allowing you to use the phone like a tiny laptop computer. It will ship with Android, but the plan is to also make GNU/Linux distributions including Debian and Ubuntu Touch available for download.

First announced by Planet Computers in March, 2020, the phone went up for pre-order through an Indiegogo crowdfunding campaign that raised more than $1.6 million in hopes of shipping the Astro Slide to customers by March, 2021.

Now the makers of the phone are providing an update – because of pandemic-related delays it will likely ship in June instead. And the specs have changed (the phone has more RAM than initially planned, but a less powerful processor and smaller battery).

  • Librem 5 Update: Shipping Estimates and CPU Supply Chain

    It’s been a busy holiday and New Year’s season at Purism as we continue to ship out Librem 5s to backers each week. We know for those who haven’t received their Librem 5 yet, what they most want to know is when their Librem 5 will arrive. In summary, we will be providing shipping estimates within the next week to the backers within the original crowdfunding campaign (orders through October 2017), but not all backers yet, based on our confidence in the estimates. The rest of this post will explain what is going into our shipping estimates, and why we can’t yet provide shipping estimates to every backer.

  • Purism and Linux 5.9 and Linux 5.10

    Following up on our report for Linux 5.8 this summarizes the progress on mainline support for the Librem 5 phone and its development kit during the 5.9 and 5.10 development cycles.

    Librem 5 updates

    One of the most notable additions is a first devicetree description for the phone. This is important to have upstream since it describes how the hardware is wired up. Without that, it’s impossible to boot a mainline kernel. We added descriptions for the various phone revisions themselves (up to the Dogwood board) and also for the MIPI DSI controller of the imx8mq SoC. From this point on, we’ll incrementally add the missing pieces, for example from the display stack, just like we’ve done for the devkit back in Linux 5.2.

  • Hack together your own e-paper smartwatch with this $50 open-source kit

    The battery life SQFMI estimates depends on your use case — it says if you’re just keeping time you should get five to seven days, but if you’re fetching data frequently you may only see two to three. Its open-source nature, however, means that you could always fit a larger battery into it, or try and make some software optimizations if there are features you’re willing to cut.

The Pyra Handheld Linux PC is Shipping

Filed under
Gaming
Gadgets

The Dragonbox Pyra is finally shipping! This small handheld Linux PC (that can be used for just about anything, including gaming) has been in the works for 7 years or more. It was designed to be the successor of the Open Pandora (an excellent device that predates smartphones) which led to numerous innovations in the ARM space (the creator of Box86, for example, comes from the Open Pandora community).

The DragonBox Pyra has had a difficult development process, with numerous hardware (and mold) related issues during its design. It was kind of supposed to be ready to come out a few years ago, but every time you’d think “hey, it’s just 2 months away now!” it would be delayed again and again – for yet completely valid reasons. Why do I say valid reasons? Well, EvilDragon (Michael Mozrek) who leads the project, is a very transparent kind of guy and details every issue and every potential solution along the way with the community. It’s probably one of the most open projects in that sense – nothing was ever hidden from the public.

Can a Linux phone replace my iPhone or Android device?

Filed under
GNU
Linux
Gadgets

At the same time, there a growing number of Linux distributions designed to run on smartphones. There are currently at least 17 different software releases available for the PinePhone, for example. Some of these operating systems are designed for a specific device (like the PinePhone), while others, like Ubuntu Touch or postmarketOS can also replace Android on many existing smartphones from Samsung, Motorola, OnePlus, Xiaomi, FairPhone, and others.

But as of mid-January, 2021 most Linux distributions for smartphones are very much a work in progress. Some features may not work. You may not be able to run the apps you’re used to using with other operating systems. And some of the best phones designed to run Linux are very much aimed at open source enthusiasts rather than the general public.

The rapid progress of Linux smartphone software development has been fascinating to watch, and Linux phones can be a lot of fun to tinker with, which is why I started this website to focus on this new and exciting space in the smartphone market.

But should you buy a Linux phone to replace your iPhone or Android phone? Maybe. But for most people, the answer is probably not. Or at least not yet.

  • Ingo Juergensmann: Migrating from Drupal to WordPress

    If you can read this on planet.debian.org then migrating my blog from Drupal to WordPress was successful and the feed has been successfully changed by the Debian Planet Maintainers (thanks!). I’ve been a long term Drupal user. I think I started to use Drupal since it was included in Debian. At some point Drupal was removed from Debian and I started to use Serendipity instead. Later Drupal was included in Debian again and I moved back to Drupal. I think this must have been around Drupal 4 or Drupal 5. No idea. I even became active in the Drupal community and went to one of the first Drupal barcamps in Germany, namely in Cologne. This was shortly before Dries Buytaert started a business off of Drupal and went to the USA. I met with many devs of Drupal in Cologne and enjoyed the community and started with others a local Drupal User Group in Rostock. [...] So, after all the years my Drupal journey will come to an end. It was a long time with you. Sometimes joyful, sometimes painful. I wish you all the best, Drupal!

  • Red Kubes Container Platform Flies Open Source Flag

    Red Kubes, a Dutch-based startup, open sourced a free community edition of its Otomi Container Platform in a bid to remedy the ongoing complexity surrounding Kubernetes configurations. The scalability, agility, and speed-to-market advantages that Kubernetes offers have been handsome enough to capture a growing share of the enterprise market, but this very strength can become an Achilles heel for container deployments. In this sense, it’s far too easy – and common – to create thousands or even tens of thousands of containers across applications. Not only does this create an operational money pit, but management becomes a herculean feat to any container newbie.

  • Shots fired in disputes over OSS-as-a-Service

    Cloud services are the great disruptor of both IT organizations and vendors, and wrapping open source software around a service is the latest flashpoint. The open source development model has proven to be an incredible incubator of innovative software by democratizing and distributing the conception, design, implementation and debugging of new titles, advantages that were thoroughly explored more than two decades ago in the book, The Cathedral and the Bazaar. Although open source has since been adopted, encouraged and sponsored by every major software company, its origins were decidedly non-commercial with utopian overtones of liberating code from the tyranny of proprietary shackles. The earliest open source projects, notably Gnu Emacs and other tools from the Gnu Project, embraced this idealistic ethos with a restrictive, comprehensive license, GPL, that applies to derivative work using the code.

  • ROC and Precision-Recall curves - How do they compare?

    Both curves offer two useful information: how to choose the positive class prediction threshold and what is the overall performance of the classification model. The former is determined by selecting the threshold which yield the best tradeoff, in adequation with the prediction task and operational needs. The latter is done by measuring the area under the curves which informs about how good the model is, because by measuring the area under the curves, one computes the overall probability that a sample from the negative class has a lower probability than a sample from the positive class. With scikit-learn, the values can be computed either by using the roc_auc attribute of the object returned by plot_roc_curve() or by calling roc_auc_score() directly for ROC curves and by using the average_precision attribute of the object returned by plot_precision_recall_curve() or by calling average_precision_score() directly for PR curves.

Open Hardware: Raspberry Pi, Arduino, Thomas Petazzoni (Bootlin) on Training

  • Qsync fixed on the Pi4 and FF compiled

    The Raspberry Pi4 does not have a hardware battery-backed clock, so relies on getting the date and time from an Internet time server. In EasyOS, Qsync is the utility that does that. At first bootup, QuickSetup has a checkbox to enable getting time from the Internet, which will launch Qsync. At first bootup on the Pi4, if you are going to connect to Internet via wifi, not ethernet, then there won't be an immediate Internet access. No problem, Qsync will run once the Internet connection is established. Qsync will run just once at bootup and after Internet connection. That's fine, but I couldn't understand why it would suddenly stop working. Then discovered that /etc/init.d/qsync was getting its executable-flag cleared.
