HP exec says quiet part out loud when it comes to locking in print customers

Re: I rather like HP printers and Instant Ink

Do they do one with duplex printing and duplex ADF scanning? I use my HP more for scanning that I do for printing, and last time I looked laser all-in-ones with duplex ADF scanning were larcenously expensive.

I rather like HP printers and Instant Ink

Yeah, go ahead, downvote me. I care not a jot.

For 99p a month, I get a solid printer with good, genuine ink cartridges, which can go through its profligate head-cleaning routine as much as it likes because I'm paying per page. Which means when I occasionally need to print, I know the printer is going to work, unlike the previous Canon and Epson units, which hated occasional use and let you know by drying up and refusing to print until they had been fed new cartridges.

Very occasionally I have a busy month, and have to increase the Instant Ink subscription to £2.99 for that month. And the software is great, you can increase the sub, then immediately decrease it, and you get a single month at the increased rate, so there's no need to remember to decrease it later.

<shrug> Works for me.

China's Loongson debuts processor that 'matches Intel silicon circa 2020'

Re: Good enough

Yup. I'm typing this on a PC with a 12th-gen i9, 64GB of RAM, and an NVMe SSD on the motherboard. Which mostly gets used to access websites and do simple Office applications work.

I'll be replacing it next year, probably with something ARM-based, but the reality is that it is *massively* over-spec'ed for my usage. (And, yeah, the components will get re-purposed when it is replaced, they won't go to waste.)

Sam Altman set to rejoin OpenAI as CEO – seemingly with Microsoft's blessing

Re: Mmmmm

1) If a society started basing major governance decisions on divining rods and tarot cards, that would be very bad indeed.

2) AI has a small but still non-zero chance of developing into something that could be species-ending for us. Yes, that's very much an edge case, extremely unlikely, but the consequences are so extreme that it needs to be taken seriously. Which is exactly what I was referring to when I said I would like to know why the relationship between board and CEO fell apart - was one of them not taking the possibility seriously enough? Or taking it too seriously? Or something else? I'm not pre-judging anything here, I'd just like a bit more information.

Mmmmm

I wonder if we will ever find out what the reasons were for Altman being sacked back at the start of this? I'm mostly positive about the future for AI, but it has to be recognised that there are paths it could take which could be rather bad, and so it would be interesting to know what was behind this organisation falling apart.

Intel integrated graphics and some other stuff

I've been using Intel's on-chip graphics stuff for years in my main PC, to simplify the PC build and keep costs down. They've been more than good enough for my needs for a long time now, with any serious 3D gaming kicked off onto an XBox.

The new Snapdragon X stuff from Qualcomm is looking even better than that, with a welcome return to a nice simple CPU core. I personally think that we went down a serious dead-end as soon as we started doing things like OoOE and massively complicating the CPU core as a result. In any world that contains decent multi-threaded processing, that sort of complication just isn't needed for general-purpose computing.

Re: Clearing stage zero is again the primary aim...

Mars gravity is approximately one third that of Earth, so take-off requires one-third the thrust like for like. However, the rocket is likely to be mostly empty at that point, and carrying little weight of fuel, so it's even less than that.

The very thin atmosphere makes no difference to powered landings, as I understand it, only parachute or winged landings.

Re: Re-use

We are getting on from as far away in time from the Apollo programme as modern cars are away from the Ford Model T. Perhaps more pertinently, we are further away in time from Apollo than Apollo was from the Wright Brothers. Engineering refines and improves stuff over time.

Re: no sane person

The big leaps in technological progress are mostly made by people considered not entirely sane at the time.

In this case, there's a very good reason for using methalox as propellant, which is to make it sustainable. CO2 and water can be turned into methane and oxygen relatively easily, using only electricity as an input, which means that launches can be made an essentially zero-carbon closed-loop process. This also means that, longer term, propellant can be manufactured off-Earth, which is critical to serious spaceflight.

Will the project succeed? I have no idea, but I'm bloody glad that someone is trying, and if anyone can make it work, it's SpaceX.

RAM and SSD

I absolutely agree, where the RAM and SSD are on separate chips.

However, pretty much the one and only thing Apple have done of which I approve in the last couple of decades is to move the RAM onto the CPU package itself. Conceptually, even more problematic than soldering it to the motherboard, but that really is where the memory belongs, now that we have the transistor count to do it. Me, I'd love a system with both RAM and SSD on the CPU package - I wonder if Qualcomm will oblige?

Re: poor idea, should have never got out of the testing labs

Not that much of a U-turn. Keyboard shortcuts, including the Windows key, have pretty much always been the secret to an easy, smooth working day in Windows. This is why I liked Windows 8 & 8.1 when everyone else hated it, because the keyboard shortcuts continued to work perfectly and it was a much better operating system under the covers than Windows 7.

Also in a high percentage of cases you can immediately double the figure for saved energy as you don't need to remove the resultant heat with air conditioning. Almost, but not quite, every single watt of energy that goes into a computer comes out as heat.

Re: My prediction ....

Attitude does not trump physics. That nice Mx. 42656e4d203239 stated that the difference in velocity between the asteroid belt and the moon is huge, and they were quite correct.

Mining the asteroids is feasible, but it's *way* easier to transport the machinery out to the asteroid, mine and refine the materials, then transport back only the stuff you want, which will be the very rare materials that are worth the investment in propulsion to overcome that difference in velocity in either direction. Moving the entire asteroid into Earth orbit is a massive waste of energy.

Forcing Apple to allow third-party app stores isn't enough

Geoff Campbell Silver badge

Re: It's not whether the App Store is good or bad...

Not all of the UK tax take comes from individuals. There's Corporation Tax, various import tariffs, some VAT (there's a bunch of companies who cannot register for VAT, and therefore cannot claim it back), duties on optional purchases, and so on.

Also, I think you might be underestimating the cost of health insurance in the US, but it's not something I have much experience of. Do you have figures available?

Cops cuff pregnant woman for carjacking after facial recog gets it wrong, again

Black Helicopters

Re: Perhaps facial recognition isn't the issue

"Trust" does not mean what you apparently think it means.

If a small percentage of police officers are crooked, or incompetent, or insane, or possibly some combination of all three, then it becomes foolish to trust any police officer (and that counts double if you are female, or from an ethnic minority, or disabled, or...). Which places a responsibility on any individual police officer to demonstrate *very* early on in any interaction with the public that they are both trustworthy and competent. And I'm afraid to say, over the course of my life, I have not yet met one single police officer in an official capacity who understands this.

One to watch

It has long been the case that early generations of challengers in any market are less capable than the incumbents. It has also long been the case that challengers sometimes win, by rapid iteration, understanding the market better than the incumbents, and very simply undercutting on price.

Still, that's never a guaranteed outcome, more often than not the challengers fail after a promising start. So, as I'm saying increasingly often these days, we will just have to wait and see what happens. I like saying this, because it seems to *really* wind up almost everyone, whether they are pro or anti. It seems not taking sides is the most radical stance one can have, in the modern era.
