### AI overview

Pine64 disclosed that some current Desktop PinePower V2 units may show 0V on their USB-C ports even though they output the correct voltage. The issue cannot be fixed by users because the MCU must be flashed at the factory; corrected batches are planned, but their production timing is unknown.

### Source excerpt

Hey everyone, we'd like to make a public disclosure to the community about a product currently selling on the PineStore website (pine64.com). The current Desktop PinePower V2 batch has an issue where in some situations the USB-C ports will report "0V" when there is obviously something attached. In reality it is actually outputting the correct voltage. This has been fixed for future batches, but the current batch still has stock available. There is no fix available for affected Desktop PinePower V2 batches as the MCU can only be flashed at the factory. We have no ETA when the fixed batch will start production as this depends on the rest of the buggered batch being sold. We'll let you all know when the fixed ones hit the store. And please don't open your PinePower devices as they're high voltage power supplies, which can lead to serious risks.

### AI overview

This opinion article examines how defaults in digital services, apps, language, and social assumptions can make some groups seem "normal" while excluding or discriminating against others. It encourages developers and technology professionals to recognize the effects of their decisions and use defaults more consciously.

### Source excerpt

Oh, hey there! Before you read this blog post, I want to say that it contains a lot of talk about equality and how some groups of people are not seen as equal compared to others. I'm passionate about changing that. If you know that a feminist point of view makes you angry, I recommend reading but take some deep breaths before commenting. Try to be friendly, like there was actual human reading your comment. Thank you! There's a lot of power with the default. And with default, I mean default selections in (digital) services, apps, and others - but also in the fact that some groups of people are seen as the default, "normal", compared to other groups. Why I'm writing about this theme? Well, I believe that we, as developers (or, basically, any role in the tech industry), need to be really conscious of this topic so that we don't accidentally (or, in some cases, on purpose) exclude, or even discriminate, some of our users. We need to recognize what our decisions can do to actual people. In this blog post, I'll first talk about who is default and who is not, then about the default in tech, and finally, I'll discuss using the default for good. Who is Default and Who is Not? The Default in What We Don't Say The default is visible in what we don't say and what needs to be explicitly said. Let's take an example from sports: When writing this post, the FIFA Women's World Cup is ongoing. Do you know what the men's tournament is called? FIFA World Cup. There is no mention of men; it's just an assumption that everyone knows it's about men; it's the default. However, I want to mention that I love how Finnish YLE (the national broadcasting company) is talking just about "Jalkapallon MM 2023", meaning Football/Soccer World Championships 2023 -- so they don't mention gender. That is, of course, a problem for some; some Finnish people have complained online that it should be called women's football. Well, the same people have a history of saying that they're defending women's rights in

### AI overview

This Mobile NixOS project update covers merged bug fixes and minor changes, an Asus Zenfone Max Plus (M1) port, external device definitions, and updates to the boot GUI. The GUI changes add independent mouse and touchscreen support, keyboard-driven input, and navigation with volume keys and the power button.

### Source excerpt

This update is the ninth in a series of regular updates on the state of the project. Only changes that have been accepted and merged in Mobile NixOS are chronicled here. There's always more work currently in-progress. Notable changes As with last month, a big part of the 10 pull requests merged were bug fixes or minor changes. Though some valuable work was also finished. Asus Zenfone Max Plus (M1) The port for asus-x018d is mainly notable for being the only alternative system to the OEM-provided Android system, with the exception to a TWRP that is using the OEM-built kernel. This means that, for the first time, Mobile NixOS this is the only alternative system for a device, including other Android-based systems. Finishing with a last note, this device has an older Mediatek SoC, compared to the other ported Mediatek device. There is not much to say, except that it was found that older Mediatek devices may exhibit a similar quirk to Qualcomm devices, where the framebuffer has to be refreshed explicitly for the display to be updated. External device definitions I hesitate to openly discuss about this pull request, as it might make contributors think they should not contribute their devices back. #162 adds a mechanism to maintain and build external device definitions. These external definitions should only be used for devices that are not welcome to the main project. The main reason a device would not be welcome is if it is not a "Mobile device". An example of such a device is the Pinebook Pro, which is a laptop. Another example would be porting to SBCs like a Raspberry Pi. Updates for the boot GUI This change, #189, is where most if this month's development time was spent. The toolkit used for the boot GUI has been forked and adapted to serve the goal of providing a GUI for mobile devices better. As part of the changes, some minor UX (User eXperience) changes have been made, but more importantly, major changes like properly supporting mouse and touch screens in an indep

The article argues that Mac laptops need a macOS Low Power Mode similar to the feature on iOS. It presents disabling Intel Turbo Boost as a practical workaround and reports testing on a 16-inch MacBook Pro showing lower peak CPU power consumption and temperature, quieter fans, and reduced heat, with performance trade-offs in some workloads.

### Source excerpt

In light of today's rumor that a Pro Mode may be coming that seems to offer benefits in the opposite direction,1 I wanted to re-make the case for a Low Power Mode on macOS -- and explain why now is the time. Modern hardware constantly pushes thermal and power limits, trying to strike a balance that minimizes noise and heat while maximizing performance and battery life. Software also plays a role, trying to keep everything background-updated, content-indexed, and photo-analyzed so it's ready for us when we want it, but not so aggressively that we notice any cost to performance or battery life. Apple's customers don't usually have control over these balances, and they're usually fixed at design time with little opportunity to adapt to changing circumstances or customer priorities. The sole exception, Low Power Mode on iOS, seems to be a huge hit: by offering a single toggle that chooses a different balance, people are able to greatly extend their battery life when they know they'll need it.2 Mac laptops need Low Power Mode, too. I believe so strongly in its potential because I've been using it on my laptops (in a way) for years, and it's fantastic. I've been disabling Intel Turbo Boost on my laptops with Turbo Boost Switcher Pro most of the time since 2015. In 2018, I first argued for Low Power Mode on macOS with a list of possible tweaks, concluding that disabling Turbo Boost was still the best bang-for-the-buck tweak to improve battery life without a noticeable performance cost in most tasks.3 Recently, as Intel has crammed more cores and higher clocks into smaller form factors and pushed thermal limits to new extremes, the gains have become even more significant. Here's some thermal testing from my 8-core 16-inch MacBook Pro: 16-inch MacBook Pro (Late 2019, 2.4 GHz 8-core i9) Power Temp. Geekbench 5 single/multi xcodebuild Normal 82W 90°C 1260/7386 39 sec.

### AI overview

This opinion article reflects on the early era of garage-built personal computers and argues that small, mission-aligned teams can create impactful computing systems. Drawing on The Soul of a New Machine, it emphasizes passion, accomplishment, self-fulfillment, expertise, and trust over power or recognition.

### Source excerpt

From the Intel x86 Manual: In the mid-1960s, Intel cofounder and Chairman Emeritus Gordon Moore had this observation: "... the number of transistors that would be incorporated on a silicon die would double every 18 months for the next several years." Over the past three and half decades, this prediction known as "Moore's Law" has continued to hold true. Moore's Law is coming up a lot lately in the context of coming to an end. It's kind of been a running joke for quite some time though so I think there is still a bit of skepticism around claiming it's ending. However, Moore's Law ending can mean a lot of different things for the future of computing. Golden Age of Garage Computer Builders Personally, I look back on the golden age of computers as the time when people were building the first personal computers in their garage. There is a certain whimsy of that time fueled with a mix of hard work and passion for building something crazy with a very small team. In today's age, at large companies, most engineers take jobs where they work on one teeny aspect of a machine or website or app. Sometimes they are not even aware of the larger goal or vision but just their own little world. Back in the garage computer building era (or so I will call it), a very small group of people aligned on a mission could create something bigger than themselves and have immense impact. This is more aligned with how startups work, in my opinion, in that small groups of people with the same end goal build something together. Soul and Passion This break I read The Soul of a New Machine, thanks @bcantrill for the recommendation. (He also wrote an amazing blog post on it.) In the book, a small team built an entire machine. The book really hit home for me on so many levels. The team wasn't driven by power or greed, but by accomplishment and self-fulfillment. They put a part of themselves in the machine therefore producing a machine with a soul. The chapter 15 of The Soul of a new Machine is so powerfu
