w0utert··on Sriwijaya Air flight SJ182, a Boeing 737, has disappeared from radar
Judging from the flight path and altitude data that seems extremely unlikely, it looks like the plane just fell apart and came down like a brick in an instant.

For the second word he says 'my ex girlfriend...' and then guesses the dutch equivalent of the word 'cunt', basically.
w0utert··on Sony publishes an official Linux driver for Playstation 5 DualSense controllers
Latency is fine, I don’t use the Xbox controllers with Linux for the reasons I mentioned but I do use them in BT mode with the Steam Link. Never had any problems with input lag. PS4 controllers are BT only and absolutely no problems with those with either PS4 or Linux. In terms of versatility and support the PS4 controllers are my favorite, but I slightly prefer the ergonomics of the Xbox One S controller.
w0utert··on Sony publishes an official Linux driver for Playstation 5 DualSense controllers
Yes I was referring to the updated controller they started shipping when the Xbox One S was released, I'm pretty sure that's the only one they have been making afterwards until the Series X was introduced?

These controllers use some kind of DRM that requires disabling a feature of the BT stack (ertm) using a non-persistent kernel parameter that breaks other BT devices. I

>> Xbox One controllers also work flawlessly in Linux

It doesn’t, actually. It works out of the box if wired through USB, or when using the expensive wireless dongle, but it doesn’t work out of the box over Bluetooth. You have to apply nasty hacks to the BT stack to make it work. PS4 controller is just pair & go.

w0utert··on Cyberpunk 2077 runs on Linux through the Proton compatibility layer
I'm almost 100% convinced that sooner or later Google will start to turn the thumbscrews on the free tier as well, they are not a charity. Either by annoying you with an increasing number of ads or otherwise mining your data, or by technical restrictions that make it almost impossible to enjoy without upgrading to a paid tier. The most likely end game I see is to apply the YouTube model to Stadia as well. So the question is if and for how long Stadia will have that advantage...
w0utert··on Apple Preps Next Mac Chips with Aim to Outclass Highest-End PCs
I should keep this in mind when I upgrade my workstation some time in the future. I have an x470 Taichi and there the IOMMU grouping is pretty bad, it also has only a single USB controller in its own group, and all PCIe slots except the top x16 one are grouped with other stuff so it's not even possible to plug in a separate USB controller card or a second GPU for passthrough. A ThreadRipper would have been a much better choice considering I also use this machine for development and can use all the cores I can get.
w0utert··on Apple Preps Next Mac Chips with Aim to Outclass Highest-End PCs
That's pretty cool! I run one gaming VM on my 3900X but I always wondered how well it would be able to handle 2 Win10 VM's playing games concurrently. Do all the other components of the solution (both hardware and software) scale well enough for that? I assume threadripper has enough PCIe lanes and IOMMU grouping that allows for 2 passthrough GPU's + 1 for the host?
w0utert··on Face masks considerably reduce Covid-19 cases in Germany
Thanks for the summary, this confirms what I already suspected, which is that these kinds of studies are pretty much useless to correlate anything with anything.

On top of that it seems the study hypotheses for these papers are clearly biased towards proving a positive correlation between infections and mask use, even though one could do exactly the same kind of study in many other parts of the world where infections exploded along with increasingly expansive mask mandates. For example France and Spain, where numbers only started to go down after they went into second lockdown.

No matter what you think of mask effectiveness, cherry picking statistics is bad science, and so far that’s all I’ve seen as far as the ‘masks are effective’ studies go.

w0utert··on 64-bit RISC-V core claims 10x better CoreMarks/Watt compared to other 3-5GHz CPU
Just a few low-activity OS & mostly sleeping application threads will barely fill one or two of these typical 'slow' cores you see in big.LITTLE SoC's, so what's the point of adding more of them?

I don't think lack of general-purpose cores has been a problem for mobile for a long time. I see much more value in heterogeneous SoC's that integrate multiple application-specific blocks that can only do a few things but do them very, very efficiently. This is pretty much what the industry has been moving towards for the past few years anyway, the Apple M1 being a good example of that.

w0utert··on Apple’s M1 silicon is all about platform control
>> Google allows third-party app stores and most of the source code for Android is out there in the open.

Is that true though? I though pretty much all of the Google services and vendor-specific skins and OS modifications are just as closed as iOS? Last time I heard vanilla AOSP is pretty much unusable because besides the core OS functions everything is grossly outdated? Is anyone using Android phones without any of the Google services?

w0utert··on I Miss Working from the Office
I don’t understand this comment, do you suggest all forms of social contacts are created equal and people should just replace the social interactions they used to have with co-workers by visiting their family more often, organizing more poker nights with friends or taking salsa classes or whatever?

That makes absolutely no sense, these interactions are completely different from those you would have with your co-workers, and it’s perfectly normal even for people with an otherwise active social life to miss those. My friends and family are almost universally incomparable to my coworkers in almost every way.

w0utert··on 16-inch MBP 2x slower than M1 MacBook Air in a real-world Rust compile
Yes but the point is that Apple doesn't need to scale the M1 up to desktop frequencies, because it already is faster than x86 in single-threaded workloads, at lower clocks and significantly lower power. To scale up the multithreaded performance they just have to increase the core count and scale the cooling system accordingly, ie: exactly like you would have to for x86. A decent desktop cooler can dissipate enough heat to run CPU's with 100+ Watt TDP's, while the M1 in the current Mac Mini sits around ~20W estimated if you discount the RAM.

So again, what would make anyone think that an M1 with decent cooling would not be able to maintain the current ST performance indefintely, or a hypothetical 8+8 or even 16+16 core M1X or M2 with a TDP of 100W and top-notch cooling solution would be impossible?

w0utert··on Games released before PS4 are no longer appearing in search on PlayStation.com
>> Had the PS4 been a PS3 with a new GPU and a clocked up Cell with an extra PPE would that have been a bad thing?

Probably, if only because non-exclusive AAA games already cost tens of millions of $$$ to develop, and no other consoles or PC's show any similarity with the Cell architecture. So you would either end up with really crappy PS versions of multi-platform games, or they would not be made for PS at all.

w0utert··on Games released before PS4 are no longer appearing in search on PlayStation.com
Rpcs3 is extremely impressive, but remember it took 9 years to get to the point where it is now, and still many games break or have unplayable performance even on the highest-end PC's you can buy today. So it kind of proves the point how ridiculously difficult it is to emulate that machine.
w0utert··on 16-inch MBP 2x slower than M1 MacBook Air in a real-world Rust compile
>> We already know the A-series of chips performs incredibly in short workloads. We have no information yet on how it performs under sustained workloads.

What makes you think that given sufficient cooling, it will not perform exactly the same as the M1 in the MBA but sustained? It’s not like the ARM architecture changes anything in the thermodynamics of cooling cpus compared to an x86 chip, right?

I’d wager that under load an i9 with passive cooling wouldn’t even last 30 seconds without throttling below even its base clock, if it doesn’t just shut down to prevent frying itself

w0utert··on 16-inch MBP 2x slower than M1 MacBook Air in a real-world Rust compile
>> I think Apple have screwed themselves over a bit here by sticking ARM-based Apple silicon in their lower-end/entry level devices first.

I’m pretty sure Apple already has an 8+8 core version with 32GB+ RAM in their lab that runs at higher clocks and blows the doors off the performance of these M1 chips, and they are simply going for maximum shock effect by releasing this ‘low-end’ chip first then tighten the screws to Intel and AMD even further when they release the MBP and iMac with an M1X chip or whatever they will call it.

w0utert··on Covid Took My Grandfather. But It Wasn’t What Killed Him
Yeah it's a lot easier if you are an island, go into super strict lock-down, and can do super-efficient (and privacy invasive) contact tracing before the number of infections even goes over 1 in 100K, like in the countries you mentioned. ..

That doesn't contradict anything I said though, I was only commenting on the US situation and whether it could have been contained by 'just wearing masks'.

w0utert··on Covid Took My Grandfather. But It Wasn’t What Killed Him
This part of the US perspective on covid-19 I don't understand.

Everywhere I keep reading comments that suggest you pretty much deserved what you got and americans only have themselves to blame because 'if everyone just wore masks' it 'could have been contained'. Literally nothing suggests that, no other country in the world shows any statistics to back this up, and the situation is pretty much as bad as or worse in many parts of the world that did mandate masks and had lock-downs, while it is much better in other parts of the world that did none of these things. Europe is the prime example of this, there's so much variation in the measures that different countries took, but I literally see zero correlation with infection rates or deaths, not up until the point where countries go into lock-downs that dramatically limit the movement of people and the chance of getting in contact with 'strangers' that you would never get in contact with if you worked from home, did not go to bars or restaurants, did not use public transport, etc. But these measures are not sustainable long-term, so sooner or later they are relaxed and the infections start to go up again, with or without face masks, with or without people doing 'everything in their power to stop the virus' because they are traumatised by the first wave. Just look at Italy, one of the hardest hit countries in Europe in the first wave, and the place they are now in again. If anything, the countries that were the first to issue mask mandates and kept expanding them (Italy, France, Spain, Belgium) are now all at the bottom of the list in terms of covid infections and deaths in the second wave.

I'll probably get downvoted into oblivion by saying as much because it's already clear to me that in the US wearing face masks is more like a religion or a political statement, but alas... The main point I wanted to make is that blaming yourself and others for the situation you are in because it 'would have been easy to contain, if only...' is not backed up by any evidence, and IMO just a form of self-torture.

w0utert··on Apple Silicon M1 Emulating x86 Is Still Faster Than Every Other Mac
I'm pretty sure Intel has had some EUV tools installed for some time already, they're just not using them for any kind of HVM yet as they are ~3 years behind their own process technology roadmap by now.
w0utert··on Apple apps on Big Sur bypass some firewalls and VPNs
Yes, but it's only useful when connected to your home LAN where you have control over the router, and even then only if you know how to set it up.

Edit: also not sure if the router I got from my ISP (which I don't use, but I guess 99% of their other customers do since it is non-trivial to replace without losing IPTV) would allow me to configure it as a VPN gateway. Pretty sure it won't considering they try to lock it down as much as possible.

w0utert··on Apple apps on Big Sur bypass some firewalls and VPNs
If this Apple firewall nonsense sticks I can see a market emerge for self-contained USB ethernet/wifi dongles that incorporate a built-in router/firewall with VPN functionality. You could build something like this yourself using an rPI or something similar, but my feeling is there could be a sizable market for a small & cheap off-the-shelf device you just plug in.
w0utert··on Apple Silicon M1 Emulating x86 Is Still Faster Than Every Other Mac
>> I know they were one of the earliest investors in ASML’s EUV.

They may have been one of the earliest investors in EUV (along with TSMC, by the way), but in terms of adoption and roadmap they have been way behind both TSMC and Samsung. I don't know the exact numbers of machines but my educated guess is that TSMC and Samsung together probably have close to 10x the EUV wafer capacity compared to Intel. And have had it for much longer as well.

The problem Intel created for itself is that they have always had a very stubborn over-confidence in their own knowledge of process technology, and have driven tool manufacturers like ASML to work within Intels constraints, instead of working together to alleviate them. Their hubris has bitten them now that EUV has become economically viable compared to Intels process technology that relies heavily on triple and quadruple patterning, and very little of Intels 'old' process technology knowledge carries over to EUV.

TSMC has also had a lot of teething pains with EUV but they have been very determined to make it work, and that's paying off now.

w0utert··on What distinguishes great software engineers? (2019) [pdf]
This rings close to home for me, I'm a firm subscriber of the mantra that laziness a good quality for a software engineer to have. It has saved me many times already working on difficult/never-seen-before problems, and (conversely) not adhering to it has bitten me multiple times.

Often it simply takes some time for solutions to new problems to percolate, and you need to take a step back regularly during the process. Forget about the problem completely and do something completely different, interspersed with short bursts of research and reading on related topics. Sooner or later the contours of a solution will start to form and you will (hopefully) be able to realize it much quicker and at higher quality compared to 'working hard' by pounding yourself and trying to force things.

I cannot count the number of times I almost gave up on a problem after working myself into multiple dead-ends, and almost instantly seeing a path forward after taking a few steps back and allowing my brain to work itself out of these dead-ends.

Not spending 1 week of 'hard work' on a bad solution can save you months of work in the future.

w0utert··on A visual comparison of macOS Catalina and Big Sur
In the case of the tool buttons in macOS windows my feeling is that this is really is splitting hairs. Literally everything that is not the same color as the toolbar itself is clickable. The frustration or the supposed 'cognitive overload' is purely theoretical.
w0utert··on A visual comparison of macOS Catalina and Big Sur
The buttons do highlight when you move over them, so it's entirely clear if you hit them if you would click. Or is that not what you mean by the 'affordances' of these buttons?
w0utert··on Apple Silicon M1 chip in MacBook Air outperforms high-end 16-inch MacBook Pro
Yes, but code signing can be ad-hoc, can be done automatically at build time, and doesn't require notarization. So it's basically just a way to ensure the binary has not been tampered with. I don't really see the problem here, as the code signing itself does not prevent any kind of code from running on macOS Big Sur.
w0utert··on Apple unveils M1, its first system-on-a-chip for portable Mac computers
If you hold Fn you get the traditional row of function keys, which seems like a pretty good tradeoff. And if you really hate that, you can simply configure the touch bar to always display them, in which case literally the only downside is that they are not physical keys anymore. Do people really touch-type the function keys so heavily that this becomes a an actual annoyance and not just an ideological one?

Adding an extra row of physical keys that do the same thing as the row of virtual function keys, at the expense of trackpad size and possibly ergonomic (harder to reach the touch bar) doesn't make a lot of sense IMO.
