Comment Why maping (Score 1) 99

Maybe it's me who lived in apartment with much simpler floor plans than everyone else, but I never saw the need for room mapping and navigation.
I've always use the randomly going around and bump into things models, and they have always been good enough for the daily cleans in house with cats.

I really don't care how silly they bump into thing as long as they keep the pet hair low in their daily runs.

What I do care about are the batteries, but luckily after-market LiIon batteries that integrate their own BMS inside the battery and are drop-in replacement for Roomba, boosting up the run by a large factore arre a thing.

Comment Cheap (Score 2) 127

However I suspect it would be a bit more than $10 today.

A bit, but not much. (random example off AliExpress, that use this synaptic chip)

Worse yet, such a setup would most certainly add latency to an application, gaming, that is sensitive already to any delays. Gaming is what drives the 120Hz and above refresh rates...

There's no real reason why latency should be more than a couple of "scan-lines" (well, at least the DSC's equivalent horizontal-lines, if the signal needs conversion between compression variants). And there's a big incentive: less on-chip built-in RAM - it's litteraly cheaper to make the chip only keep the most recent relevant data and immediately start streaming out the HDMI 2.1 signal as soon as possible, rather than keeping multiple entire frames.

Comment Dongles (Score 1) 127

I fear that most DisplayPort to HDMI 2.1 dongles are not active adapters but instead passive physical connection switches.

Most, but not all. I litterally have a DisplayProt to HDMI + DVI + VGA combo dongle on my workstation at home.

But they tend to by a tiny bit more expensive (think 10 bucks instead of 1 bucks on AliExpress. Or 50 bucks at your local TV shop), because they require a dedicated chip inside the dongle.

Although to my frustration it has never worked the other way around with a HDMI ports being simply physical convertible to a DisplayPort.

Depends on the device. Can happen in some professional projectors: some enterprise-grade projectors can litteraly support "any protocol over any wiring with enough pins", i.e.: the presence of a HDMI, DP, DVI or VGA connector on a given port is mainly a convenience. This is so you could reuse wathever cabling is embed in the walls, you don't need to tear down the walls and redo the cabling (which could get expensive in a large conference room). This is also the reason you could find ultra cheap passive VGA-to-HDMI cables on AliExpress/eBay/Amazon for the last segment between the VGA port built into the lectern of some old university lecture room and the laptop outputting the HDMI that the projector is actually configured to fetch from the VGA cabling embed in the walls.

Comment SteamDeck (Score 1) 127

You can use DisplayPort instead. Is it possible to convert DP to HDMI 2.1?

Yes, that's litteraly how the SteamDeck handles this.
The SteamDeck can output DisplayPort on its USB-C connector (similar to tons of laptops and some smartphones), and the SeamDeck's Dock has a dedicated hardware chip that does the translation into HDMI signal.
This way no need to tweak any support into opensource GPL'd drivers inside the SteamDeck and then risking running afoul of HDMI's licensing restrictions.

Comment Open source drivers (Score 4, Informative) 127

cheaper to just pay the license fee

The problem is that unlike Nintendo, Sony and Microsoft, Valve isn't selling a closed box with proprietary blob.
Their hardware runs Linux with a close-to-upstream kernel(*).
Among other, they are using the FOSS stack: Linux kernel driver, user space Mesa libraries, etc.
All this is GPL meaning that the code is released (or at least pull requests with the latest are wainting to be eventually upstreamed)

And the HDMI's licencing currently prohibits making that code available (or conversly, GPL means that every body should be able to read and modify the code that does HDMI 2.1 shit even people who haven't paid the license).

(*): except for the dock. The Steam Deck's dock has a dedicated chip that does the USB-C DisplayPort to HDMI conversion, so no need to tweak anything on the drivers running inside the SteamDeck.

It's quaint that you think the United States is still a republic. It's a monarchy, and Trump's handlers are likely moving currently to make sure that when Vance succeeds him, that the Executive branch and a Congress that will be, through the use of naked force if necessary, remain filled with Republican paper tigers to complement the paper tigers in the Supreme Court, settles into the oligarchy the Framers always really intended it to be. The military will largely be used to recreate the American hemispheric hegemony. The National Guard and ICE will be used as foot soldiers within the US to "secure" elections.

The morons that elected that diseased wicked and demented man have destroyed whatever the hell America was. As a Canadian, I can only hope we can withstand this hemispheric dominance and the raiding of our natural resources to feed the perverse desires of the child molesters, rapists, racists and psychopaths that have already taken control of the US.

Doubtless, I will be downvoted by the remaining MAGA crowd here. You know, the guys that pretended they refused to vote Democrat because Bernie wasn't made leader, but are to a man a pack of Brown Shirts eagerly awaiting the time when they imagine they can take part in the defenestration of American society.

Comment Re:Linus is right, but this is really not news (Score 1) 82

Win9x and Win2k (and the other NT descendants) are fundamentally different operating systems. In general, NT had a much more robust kernel, so system panics were and remain mainly hardware issues, or, particularly in the old days, dodgy drivers (which is just another form of hardware issue). I've seen plenty of panics on *nix systems and Windows systems, and I'd say probably 90-95% were all hardware failures, mainly RAM, but on a few occasions something wrong with the CPU itself or with other critical hardware like storage device hardware. There were quite a few very iffy IDE cards back in the day.

The other category of failure, various kinds of memory overruns, have all but disappeared now as memory management, both on the silicon and in kernels, have radically improved. So I'd say these are pretty much extinct, except maybe in some very edge cases, where I'd argue someone is disabling protections or breaking rules to eke out some imagined extra benefit.

Jokes aside about Thanksgiving...

Thanksgiving dinner costs a little more this year, govt can I has a few thousand in free money? What's the difference between those examples and texas buying btc?

The difference is that food is part of(*) rights to an adequate standard of living as per Universal Declaration of Human Rights.
Not dying of starvation is a fundamental human right.

So yeah, I get that you're joking about somebody throwing an excessively opulent Thanksgiving party and then complaining that it costs a bit much.

But making sure that every single person has access to sufficient food is a core job that government has to do(**). You can make jokes around what constitutes "sufficient", but you can't deny that nobody should die of starvation.
On the other hand, making sure that your Ponzi scheme doesn't implode before you had time to make it to the bank isn't the government's job. At best government's job would be to regulate in order to make it less likely that unsuspecting idiots get caught up in such scams.

We know it weakly interacts electromagnetically, which means one of the ways in which it is posited planets form, initially via electrostatic attraction of dust particles, isn't likely to work. This means dark matter will be less "clumpy" and more diffuse, and less likely to create denser conglomerations that could lead to stellar and planetary formation.

What this finding does suggest, if it holds true, is that some form of supersymmetry, as an extension fo the Standard Model is true. Experiments over the last 10-15 years have heavily constrained the masses and energy levels of any supersymmetry model, so it would appear that if this is the case, it's going to require returning to a model that some physicists had started to abandon.

Comment Re:But it's already loaded! (Score 1) 69

Without knowing precisely how Explorer is structured, it's conceivable that there may be different dynamically-linked libraries and/or execution points for running the desktop and for the file explorer, in which case just having explorer.exe running in and of itself doesn't mean that new modules have to be loaded if explorer.exe process fires up. The solution could very well be to load the libraries involved in file browsing when the desktop opens.

Just guessing here. There was a time when there was a lot more horsepower required for GUI elements than folder browsing, but this is 2025, and explorer.exe probably uses orders of a magnitude more resources now than it did in 1995, because... well, who knows really. Probably to sell more ads and load up more data to their AI.

That, on modern hardware, they have to preload a fucking file browser so that it pops up faster is just an indication of what a steaming pile of garbage MS is. They had sweet spots with Win2k-WinXP and with Win7, but their incoherent need to be a whole bunch of contradictory things --- with AI! has led what was a rather iffy OS and UI experience to begin with to become a cluster fuck of incoherence.

The capacity of the government of a large jurisdiction like California, or more particularly the US, could bankrupt someone like Musk, so I say, bring it on. Within a decade Musk would have abandoned all efforts, or, even better, be stone cold broke (frankly billionaires shouldn't exist at all, and we should tax the living fuck out of them down to their last $200 million).

We're too afraid of these modern day Bond villains when we should be aiming every financial, and probably every real, cannon straight at them and putting them in a sense of mortal danger every minute of their waking lives, so that they literally piss themselves in terror at the though that "we the people" might decide to wipe them out for good.
