bipson··on The Heart of RISC-V Development Is Unmatched
I didn't say it was.

I was just wondering how you define PC. Form factor or "standard connectors" (whatever that is - which RPi connector is not "standard"?) are none of my criteria.

bipson··on The Heart of RISC-V Development Is Unmatched
Oh, well I guess you can use it as a development board - granted. Never occurred to me.

Although I would expect better debugging interfaces, less hacky hardware setup, a reasonable boot-loader, etc. Some things improved over the generations, true.

bipson··on The Heart of RISC-V Development Is Unmatched
I know, this discussion is quite old (e.g. Mac vs. PC), but can you clarify how you define PC in your post?

Particularly what makes this RISC-V board a PC, what an RPi does not have? Form factor, ATX power or PCI-Express?

bipson··on The Heart of RISC-V Development Is Unmatched
Further, a RPi is not a development board.

Development boards are typically more expensive, since they are produced in lower numbers, and have features a consumer is not interested in (debugging, etc.).

Unless the manufacturer pushes development boards hard to e.g. pull developers in to the new eco-system quickly, then they might get sold at a bargain. But those are then usually not usable in place of the "real thing" (would cut into sales).

bipson··on Over 80% of Covid-19 patients in a hospital study have Vitamin D deficiency
Uhm, that seems a tad convoluted. Are you saying people that socially distance themselves are more likely to contract Covid-19 because the ones that don't are so often outside that they will contract it less probably?

And further, that's not the definition of social distancing. This would obviously include indoors. I won't sit at my kitchen table with the postman for a coffee while I am avoiding public gatherings.

I am sorry, my sarcasm-radar is quite broken. Are you joking?

bipson··on Over 80% of Covid-19 patients in a hospital study have Vitamin D deficiency
There were results from studies showing weak effects of self-protection even by "simple" surgical masks a few months ago.

Evidence seems to indicate there is such an effect - and contradicting the initial assumption that there isn't.

bipson··on Over 80% of Covid-19 patients in a hospital study have Vitamin D deficiency
How would this produce the study result?

Are people that isolate more likely to get hospitalized with Covid-19 than those that do not?

Let me try to explain:

Where I live, cars need certification/a license to be operated. The manufacturer does that for you, so you can obtain the required document quite easily for your car.

Aftermarket parts are regulated - you can't install what you want, it needs to be certified for your specific make and model (and motor variant, etc.) - otherwise your car is not legal anymore.

This applies to chip tuning as well. Since you're modifying a certified part, it looses the certification - obviously.

What new cars are allowed to emit, is strictly regulated.

Further, since this very month, we have a carbon-based tax on new cars (based upon the aforementioned certification from the manufacturer). Thus if the emissions of car are changed, you're basically evading taxes as well.

Where I live, chip tuning is almost only done to get a few HP on the cheap. And it is unfortunately very popular and nobody really cares.

Edit: You can seek in individual certification for some modifications, added to your documentation, but a tampered with ECU is not one of them I think.

There is no such thing as high quality chip tuning, unless you are replicating 100% what the manufacturer just disabled for your MCU (e.g. unlocking some kW your motor is in principle capable of outputting). But then again, e.g. BMW uses different, more reliable mechanic parts (camshaft, head, etc.) on motors that have these kWs unlocked, so you are still risking ruining your motor in the long run.

Chip tuning always meddles with curves the manufacturer chose after long consideration and extensive tests (let's just ignore VW for a moment) - and you are trying to tell me that guy from this shop just "knows better" and "sure, this will be better in every possible aspect"?

Are you trying to say a 2019 BMW out of factory will shoot out black smoke while accelerating (quite boringly) from a traffic light?

Are you talking about Tesla AutoPilot?

This system is meant for cars without level 2 driver assist, so not for Teslas.

Further, the system has no control over what "disengages" in the car itself - it is sending bogus sensor inputs to elicit a reaction according to level 2 driver assistance. Thus, if it sends such bogus inputs and fails at doing this "reliably", it will result in misbehaving steering, breaking, etc. which it does not control itself.

Further, if it was in control, my argument would stay: If your controlling device has left the building (crashed), it can also not disengage anything any more reliably.

Because that means not only you (the owner) can do it.

Also (caution, tangent): MCUs in cars is one of the systems where I want more encryption/signing and less hacking - especially for owners. Foremost to get rid of all the chip-tuned soot sources I am constanly driving behind.

The manufacturer knows how to control the engine, the random idiot with a laptop in 95% of the cases does more harm then good. If the manufacturer botched the MCU (hello VW), then he is held accountable. If he allows users to cause harm to the environment (chip-tuning), he should be held accountable too.

My main concern would be that the architecture of an OTS Android system does not offer any guarantees regarding real-time i.e. hard deadlines.

Ever had an android app or even the whole phone locking up? Even if it is only for a second or two, I don't want this to happen to a device that feeds live data into my car's controller.

Even if this is only level 2 driver assist. If a car would get a bogus "you are crossing a divider line" signal for e.g. 2 seconds, it would start to steer quite persistently (even if with limited force) in a certain direction and you would have to counter that action.

Nope, I wouldn't use this.

Only very recent cars use Flexray, and also not true for all manufacturers. CAN is still widely used, and some want to skip Flexray entirely for the next thing...

It is actually concerning that you can inject false sensor data this easily. I mean, sure, the messages on the CAN will not be encrypted or signed in any way, I know, but still...

that's not what "at your own risk" means.

"At your own risk" means you bear the risk (legally). If something happens, it is on you, and the manufacturer offloads any liability on you.

That does not imply what the risks are. Life threatening? You are risking other people's lives.

bipson··on Hacked billboards make Teslas see phantom objects causing them to swerve or stop
Well, which one is it now:

Are self-driving computers superior to humans and make less mistakes, or is it OK for a computer to be tricked by something some humans would also not detect?

Btw. I think I can tell if there is a real stop-sign or something on a billboard after some 'huh'-moment and without slamming on the brakes. And humans still go circles around AI regarding plausibility-checking very out-of-the-ordinary events.

The feedback is simply not attributable for outsiders. I don't think there is a legal argument here. And even if the VC was identified, if the writer didn't invent any of those stories (you wanted inaccuracy, right?), there is nothing he is liable for...

Or am I mistaken about US law? I think it is even worse over there, you can basically write what you want, as long as nobody can prove it outright wrong. Just imagine all the New York Post articles somebody would be sued for.

Most outright defamatory articles just end in a "Welp, sorry?"-situation and nothing ever happens, because "It could have been true, right?"

not GP, but most immigration systems violate human rights all the time by treating people as if they were people without these rights - or not people at all. Most of the time the legal leeway is based upon them not being citizens (yet). What is the path to immigration in your country?

It begins with a legal dilemma: E.g. asylum is a human right, but how to determine who is eligible? In a timely manner that is. Especially if you have thousands of applicants and (almost) no documents. How do you house people in the meantime? What rights do they have?

bipson··on Cups Printing System Open-Source Development Has Seemingly Dried Up
I would disagree. At least the gnome printer settings did not only change (for some time you had both in parallel on Fedora), they are not complicated at all?

The paperless society is a dream.

Still nothing beats printing a document, scribble on it and giving it to someone or putting it a stash on your desk - not even having a device being capable of doing those things digitally without hick-ups.

The two most important issues are:

- This device (possibly) stacks all of these papers you would have printed out - so they are lost in a sheer endless space of all these various documents and even worse versions thereof. And then if you start sending these versions to others, e.g. expecting feedback, all hell breaks loose.

- There is still something about sitting with a stack of papers in your hand/on your desk - no digital device involved. Most people can't focus on a digital version the same way they do on a physical paper. I'm a huge fan of the ReMarkable (2), but simply put every (even awesome) attempt so far has failed.

Then add to that all the hick-ups that are simply never to leave. Software incompatibilities, sharing tools not working with all devices, walled-gardens, ... the problems are still endless and just get worse with every tool you add.

How are you going to print exams for students? Forms for residents to fill out? We are not going to demand of every citizen to fill out everything online at all times, are we? That would leave the most vulnerable even more stranded than they are now.

Maybe not a community fork, but I can think of several Linux Distro "Owners"/Communities/Companies that need a working printer service for their "products", e.g. RedHat/IBM, Suse, Canonical?

Would it be too far fetched if one of them starts maintaining/sheltering a fork - at least to fix bugs? Maybe even with the help of the other interested parties (in an ideal world)?

I cannot imagine IBM wants to sit on a Fedora Workstation release with a buggy printing service.

bipson··on Cups Printing System Open-Source Development Has Seemingly Dried Up
Some (professional ones, e.g. Canon) do - additionally to offering other interfaces.

But let me tell you, it is terrible not being able to print from your system dialogue.

Then there is IPP and LPD/LPR. But those are either limited and sometimes the results not ideal (LPD), or again rely on a driver on your system to access the features of your printer (IPP) e.g. double sided printing, toner levels, print quality, etc.

bipson··on EULA Found on a Package of Fruit
A colleague of mine has a small farm which he inherited and operates as part-time-business.

He once wanted to sell some surplus seeds from a harvest to other farmers on a facebook page or similar. He was quickly reminded that he was strictly not allowed to this, since he did not own the rights. The cooperative he operates under (basically the only way farming is done here) sold/gave him the seeds and the right to plant them and resell/bring the crops to them afterwards. Everything else was "unlicensed" and would be fined harshly.

That's just the way it is - particularly with newly developed variants. Breeding takes decades and needs to pay off somehow.

For a different view on this I suggest the SciFri podcast on the new "Cosmic Crisp" Apple. Or some research on the "Honey Crisp", "Pink Lady", etc.

That and does GP have a WiFi router a few meters from the bedroom, which they always unplug at night (disclaimer: I used to do that). And the clock next to the bed? Battery or socket?

You also cannot unplug all of your neighbours routers, TVs and other devices.

It is very easy to get paranoid about specific wireless technologies, it is almost impossible nowadays to avoid "electrosmog" or particularly wireless emitters entirely though.

Yes my phone was always on silent as well - until you have your kid in daycare and are supposed to really answer your calls as they arrive.
bipson··on When You Win a Nobel and They Can't Reach You at Home
Yes, Android also has a DND-mode with configurable exceptions: what type of message/call gets through, who gets through right away, or after how many repeat calls.

Further, you can schedule it or even trigger by certain calendar events. Very convenient if you have small children and don't want the random calls from grandparents or old friends checking in at inconvenient times (apparently if they don't have children but working a lot they don't consider 9pm to be "a bad time" - how should they?).

We used Airplane mode at nights before (even before we had kids), but were stressed about missed emergencies from relatives and stopped doing that.

Disclaimer: I get approx. 2 calls per week, and this is mostly businesses calling back, etc. I still don't want to miss emergencies though.

bipson··on The AMD Radeon Graphics Driver Makes Up Roughly 10.5% of the Linux Kernel
I have Lexa PRO in my workstation (Fedora) - Suspend/Resume works so far.

I have an issue though where switching off the monitor for a few days might make the AMD card disabling the outputs and not recognizing the monitor afterwards (I think it is related to the order in which I try to "wake" the monitor) - which I cannot recover from without rebooting the machine.

But this is with a machine never going into suspend or any sleep state - and I can't say if this would be the same with the NVIDIA card. I do not use the NVIDIA card for video output because the proprietary driver would regularly stop showing my desktop - or suddenly any output at all after reboot.

The integrated Intel GPU on my laptop is mostly without issues whatsoever.

On laptops I would still recommend Intel GPUs anyway for power consumption reasons - although AMD APUs are quite interesting and I don't have recent knowledge about how well they compare. The CPU and its ability to lower power consumption under sleep is also relevant there, and this was way better under Intel so far. Unless you need the increase in performance an AMD GPU/APU would offer...

Although your argument is valid, are we talking about CUDA? Obviously CUDA is an NVIDIA thing under all platforms, right? I don't think anyone would buy AMD with the intention of running CUDA.

Regarding GPUs and how good they work under Linux, computing on GPUs is only a part of the discussion I would argue...

bipson··on The AMD Radeon Graphics Driver Makes Up Roughly 10.5% of the Linux Kernel
Agree mostly, but the best option under Linux seems to be Intel graphics (or at least was until a few years ago) - arguably not beefy enough for some things, but regarding supported features, stability and power consumption the best supported mainstream gpu in the Linux kernel.

Intel simply has no closed source driver for Linux. New hardware is often supported/merged before it is even sold. AMD is trying the same, but not there yet.
