Comment Cheap (Score 1) 45

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) 45

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) 45

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 3, Informative) 45

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.

Comment Rubio is so unpatriotic! (Score 4, Funny) 135

He wants "Times New Roman" ...
* The Times referred to is The Times newspaper, a British publication.
* New Roman is clearly linked to Italy!

He should have ordered the adoption of something like American Kestrel or one of the Disney fonts or one USA fonts. Hopefully, using his great intellect and insight Trump will admonish and correct him.

Nuclear Fission isn't cost effective ... _unless_ you price in the full eco-balance of electricity production. Then the numbers look significantly different and fission could just be a real thing once again. At least until renewables and energy storage have gained significant portions of the energy mix.

No. This is nonsense. Nuclear fuel production has a massive ecological impact. Nuclear only looks good when compared to coal. Stop doing that.

You can thank student loans for that. Earlier generations got their schooling subsidized, but now people have to get loans to pay for it themselves instead. Colleges therefore could raise tuition. Then a bipartisan effort in Congress was launched to make sure we couldn't discharge those loans through bankruptcy like you can gambling or other personal debts, which was led by Joseph R Biden. I think we know how that turned out, forgiveness for a few of the worst abused players, and blaming inability to keep his campaign promises related to partial forgiveness for all buyers blamed on Congress while he went around them to fund genocide in Gaza.

Comment Re: Physical addresses vs. mailing addresses (Score 2) 65

The USPS is also pretty crap about it. They regularly just don't bother to add new addresses to their databases for months or sometimes even years. At work we're having to use an alternate address for a multi story residence with dozens of units because of this. It's really quite irritating. Their address validation system is also shit. They will tell you for example that an address has an invalid secondary (unit number type, e.g. suite/apartment/whatever) but then won't tell you what the correct one is even though they have to know in order to tell you that the one you used is invalid. And this is when you PAY for validation! I don't know how much of this is due to DeJoy but it's shit.
