  • Screen is another thing - but I can live with that, mostly - it’s a bit hard to find x86 notebooks with decent resolution (not talking retina style, just better than “1080p on a 14 inch display”). And while the screen itself is nice on the apples I’d prefer a lower resolution one if I can get a matte screen instead.

    But fact is that nobody wants to sell you a proper x86 notebook. It’s almost impossible to find something with more than 32GB of RAM, and while there are a few with more than 64GB they’re all xeon based monsters larger than 16", as far as I can tell can’t really be ordered, and have a price tag equal or larger to a full spec 14" mac book pro. And obviously you can’t really think about battery life with intels space heaters.

    It’s especially sad as current mobile Ryzen CPUs could very well compete with Apples ARM CPUs - the one thing Apple is better at is the absolute low power state, as soon as it has too actually do something the power (and TDP) curve is very close to mobile Ryzen. But pretty much every manufacturer fucks up the thermal design, or gimps it in other ways.




  • The space used by the smallest solar charger I’ve seen on Amazon seems to be similar to 6 or more batteries in the format the N900 was taking - so if you look at space, slow charging from solar charger, and reliance on sun conditions taking individual batteries seems to be the better option for a few days hike. It’s also easier to stow individual batteries to wherever you still have space left.



  • This doesn’t have anything to do with user control - modern windows versions need drivers to be WHQL signed to get that kind of access. Alternatively you’ll need to enable developer mode on your system, and install your own developer certificate into its keyring for running own code, which has its own drawbacks.

    Crowdstrike is implemented as a device driver - but as there is no device Microsoft could’ve argued that this is abusing the APIs, and refused the WHQL certification. Microsofts own security solution (Defender) also is implemented as a device driver, though, and that’s what the EU ruling is about: Microsoft needs to provide the same access they’re using in their own products to competitors. Which is a good thing - but if Microsoft didn’t have Defender, or they’d have done it without that type of access it’d have been fully legal for them to deny the certification for Crowdstrike.

    Both MacOS and Linux have the ability to run the type of thing that requires those privileges on Windows in an unprivileged process - and on newer Linux versions Crowdstrike is using that (older versions got broken by them the same way they now broke Windows). So Microsoft now trying to blame the EU can be seen as an attempt to keep people from questioning why Microsoft didn’t implement a low privilege API as well, which would’ve prevented this whole mess.

    Not just that - intel did dual core CPUs as a response to AMD doing just that, by gluing two cores together. Which is pretty funny when you look at intels 2017 campaign of discrediting ryzen by calling it a glued together CPU.

    AMDs Opteron was wiping the floor with intel stuff for years - but not every vendor offered systems as they got paid off by intel. I remember helping a friend with building a kernel for one of the first available Opteron setups - that thing was impressive.

    And then there’s the whole 64bit thing which intel eventually had to license from AMD.

    Most of the big CPU innovations (at least in x86 space) of the last decade were by AMD - and the chiplet design of ryzen is just another one.


  • One fascinating example is one owner that replaced the DC barrel jack with a USB-C port, so they could utilize USB-PD for external power.

    Oddly enough that’s also an example for bad design in that notebook: The barrel jack is soldered in. With a module that is plugged into the board that’d be significantly easier to replace - and also provide strain relief for power jack abuse. All my old thinkpads were trivial to move to USB-C PD because they use a separate power jack with attached cable.

    The transparent bottom also isn’t very functional - it is pretty annoying to remove and put back, due to the large amount of screws required. For a notebook designed for tinkering I’d have wanted some kind of quick release for that. Also annoying is the lack of USB ports on the board - there’s enough space to integrate a USB hub, but just doing that on the board and providing extra ports would’ve been way more sensible.

    The CPU module also is a bit of a mixed bag - it pretty much is designed for the first module they developed, and later modules don’t have full support for the existing ports. I was expecting that, though - many projects trying to offer that kind of modular upgrade path run into that sooner or later, and for that kind of small project with all its teething problems ‘sooner’ was to be expected. It still is very interesting for some prototyping needs - but that’s mostly companies or very dedicated hackers, not the average linux user.


  • RDS and related protocols like TMC have specifications for both FM and AM transmitters. Those are used to stop playback if an urgent message comes. I’m assuming you have AM stations with such signals in the US (I don’t think we have in the EU) - otherwise the AM radio mandate would indeed be stupid.

    edit: did some digging (it’s been almost 30 years since I cared about that stuff) - seems the US was pretty late to the party for radio data channels, and side channels for AM (which wasn’t of that much interest here due to the FM heavy radio landscape in Europe) only was discussed in the early 90s for the US specific variants. I couldn’t find any details if that actually ever got implemented. Given that most documentation available on that topic is heavily focusing on EU I’d guess it never got that much use in the US.


  • Ability for AM radios to interrupt other playback for announcements has been around at least since the 90s. Back then it was commonly used to pause cassette playback when traffic announcements were made.

    This just requires for the device to monitor radio when on, and to be on - and with how integrated it is in modern days cars functionality I’d say the chance for them to be on is higher than it was in the 90s. So having that functionality is a pretty good way to reach a lot of car drivers.




  • Not entirely sure about that. I have a bunch of systems with the current 8cx, and that’s pretty much 10 years behind Apple performance wise, while being similar in heat and power consumed. It is perfectly fine for the average office and webbrowsing workload, though - a 10 year old mobile i7 still is an acceptable CPU for that nowadays, the more problematic areas of IO speed are better with the Snapdragon. (That’s also the reason why Apple is getting away with that 8GB thing - the performance impact caused by that still keeps a usable system for the average user. The lie is not that it doesn’t work - the lie is that it doesn’t have an impact).

    From the articles I see about the Snapdragon Elite it seems to have something like double the multicore performance of the 8cx - which is a nice improvement, but still quite a bit away from catching up to the Apple chips. You could have a large percentage of office workers use them and be happy - but for demanding workloads you’d still need to go intel/AMD/Apple. I don’t think many companies will go for Windows/Arm when they can’t really switch everybody over. Plus, the deployment tools for ARM are not very stable yet - and big parts of what you’d need for doing deployments in an organization have just been available for ARM for a few months now (I’ve been waiting for that, but didn’t have a time to evaluate if they’re working).
