    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).


  • It also is perfectly fine for running a few minute long compile cycles - without running into thermal throttling. I guess if you do some hour long stuff it might eventually become an issue - but generally the CPUs available in the Airs seem to be perfectly fine with passive cooling even for longer peak loads. Definitely usable as a developer machine, though, if you can live with the low memory (16GB for the M1, which I have).

    I bought some Apple hardware for a customer project - which was pretty much first time seriously touching Apple stuff since the 90s, as i’m not much of a friend of them - and was pretty surprised about performance as well as lack of heat. That thing is now running Linux, and it made me replace my aging Thinkpad x230 with a Macbook Pro - where active cooling clearly is required, but you also get a lot of performance out of it.

    The real big thing is that they managed to scale power usage nicely over the complete load range. For the Max/Ultra variants you get comparable performance (and power draw/heat) on high load to the top Ryzen mobile CPUs - but for low load you still get a responsive system at significantly less power draw than the Ryzens.

    Intel is playing a completely different game - they did manage to catch up a bit, but generally are still running hot, and are power hogs. Currently it’s just a race between Apple and AMD - and AMD is gimped by nobody building proper notebooks with their CPUs. Prices Apple is charging for RAM and SSDs are insane, though - they do get additional performance out of their design (unlike pretty much all x86 notebooks, where soldered RAM will offer the same throughput as a socketed on), but having a M.2 slot for a lower speed extra SSD would be very welcome.


  • You still might want to do something like alias pbtar='tar --use-compress-prog=pbzip2 to easily use pbzip2 - unless you have an ancient system that’ll speed things up significantly. And even if you don’t it’d be nice to use it for creation - to utilize more than one core the archive needs to be created for parallel extraction.







  • What you’re referring to as family friendly I would say is more accurately described as social gaming or couch co-op. The physical aspect of multiplayer gaming on the Wii certainly added something unique to local multiplayer on the console, an experience wholly unlike a group of players sitting on a couch holding more traditional controllers.

    Pretty much everybody copied it afterwards - Microsoft has Kinect, Sony has some support to use their camera for that. Switch controls can be detached for that kind of play - but there never was the high amount of well done movement games available on any other platform afterwards, and never again the good haptics of the wii remote.

    We have the wii and on of our switches hooked up to the TV - in that mode we pretty much exclusively use the wii. I recently downloaded pretty much all remaining sports and dance games to get some more variety. For the switch the cool stuff is the mario cart with physical carts, and the Labo.

    Being able to use the wii controllers and the balance board on the switch would’ve been a great thing.
