Perplexity Comet hurtling toward Amazon ban

If the access is from a browser on the user's machine then the only things identifying it as a bot are the behaviour and the user agent string. I trust my access credentials to my browser of choice, so if a user wants to risk theirs with an AI bot then it's at their own risk. I can see Amazon's point if the bot/browser is hammering the site with a lot of accesses that far exceed what a human would do when browsing, but otherwise if it's a Chromium-based browser, what's the effective difference from their end compared to using Chrome, Vivaldi or Brave? I'd say that using Chrome probably leaks way more information than some of the others.

RSS dulls the pain of the modern web

Re: Hidden RSS feeds.

Thanks for that tip, just implemented it here.

BOFH is probably stalking you...

Already Here

As it happens, I came across this article courtesy of Akregator subscribed to El Reg's RSS feed which has been a staple here for many years. Admittedly my feed list is looking a bit thin at the moment, quite a few stopped working and I just assumed (perhaps wrongly in a few cases) that the source had ceased to provide one.

Amazon tells FCC to bin SpaceX's million-satellite datacenter dream

Given that LEO satellites often get caught by the atmosphere and burn up, would you want your data stuck out there? Also more chance of bit corruption from radiation/particle effects.

TerraPower gets permission to build, not operate, sodium-cooled nuclear reactor

I was always impressed by Dounreay using molten sodium as a coolant but at some point I looked up the melting point (98C) and got slightly less impressed. I guess it's better than water because it doesn't boil until 883C, so it doesn't need the pressure that water does.

AI can predict your future salary based on your photo, boffins claim

So if companies are using this in early screening, make sure your LinkedIn picture is low-enough quality that they can't tell fine detail, lock down any photos of you that are searchable on the web and generally make it hard for people to find your image. I've checked mine and I don't appear in a Google Image search for my name, so that's a good start. I seem to share a name with authors and academics so they occupy the search results.

Microsoft engineer speedruns Raspberry Pi magic smoke in five minutes

Re: He posted this?

That's the usual thing. Quickly disconnect all the power, surreptitiously try to dissipate any visible smoke with gentle and quiet blowing and appear innocent when someone else in the room smells burning and looks around for the source. Or celebrate the achievement if it's clearly obvious. Own it and say "Impressive!" loudly. I do remember as a junior engineer producing a light-emitting op-amp when a test probe I was holding slipped and shorted something. Lasted a good ten seconds, with with everyone else panicking and me just sitting there admiring the sight because I knew it was already too late.

I'm sure people who do electronics are capable of detecting the magic smoke at concentrations well below that of the general population.

Euro firms must ditch Uncle Sam's clouds and go EU-native

Re: Not a Trump thing.

Someone researched it[*] and it was effective in some cases. The body's immune system has some control over the proliferation of intestinal parasites, but the effective Covid treatments at that point suppressed the immune system and allowed the parasites to multiply to the point where they contributed to the death of the host. So if you were in an area where parasites are endemic, taking medication to kill them at the same time as Covid treatment was effective. Outside of those areas, there was no noticeable effect.

[*] it was a published paper that tried to make sense of all the small-scale studies that either claimed it was effective or not, and noted the correlation. I didn't keep a link to it.

Bankrupt scooter startup left one private key to rule them all

Re: Law...

I was once in earshot of management of a company that was spiralling down and they were discussing what they could set in place before the plug was pulled in order that there would be enough infrastructure and information out there to allow existing users to continue using their product. So they're not all bad.

Power scarcity drives datacenters to Texas, where the juice is

Re: Did it suddenly start raining in Texas?

If they put them too close to the Gulf of Mexico then they might end up with too much water if a hurricane comes along. Water yes, but only in the correct place.

Given how well the Texas grid performed in 2021, I would steer clear of the place. An isolated grid, so they can't even pull in power from elsewhere. The pricing model imposed on residential customers (and possibly some/all business ones too) that hiked prices to gouging levels when demand far outstripped supply, means that the locals should be resisting the arrival of such power hogs.

AI may be everywhere, but it's nowhere in recent productivity statistics

For Reference Only

I find the best way to use AI is to get it to provide me with a list of useful reference articles, which I can then read and (hopefully) understand and then go use the information constructively. If I ask it to generate code then I need to spend time checking that code, if I want it to write prose then I have to spend time proofreading it and checking for accuracy. I've seen it be flat wrong before now. One day it may work well enough to just get on and do stuff, but I remain to be convinced that it is reliable outside of fairly narrow areas where it's been trained on carefully-curated content.

Techie banned from client site for outage he didn’t cause

Re: 13A plugs

One of the common causes of overheating is dirty contacts. That bumps up the contact resistance, which generates a bit of heat and a bit more oxidation, which bumps up the contact resistance, which...

I suspect part of the problem there is that most of us plug the kettle into the wall socket and never unplug it, so the wiping action of inserting the plug never has a chance to clean off the crud.

AWS builds a DNS backstop to allow changes when its notoriously flaky US East region wobbles

I assume this means they've set the default TTL on DNS queries to 60 minutes. I've done that sort of thing (except down to 10 minutes) for scheduled changes to allow IP address changes to propagate faster when a change is made. 60 minutes is probably a reasonable compromise for unscheduled outages.

Canonical pushes Ubuntu LTS support even further - if you pay

I find one of the incentives to upgrade to a new release is the rest of the world. If you're stuck on a distribution that uses Python 3.4 (assuming it's new enough to have made it to V3) then a lot of stuff needs a newer rev. Similarly with other things, you're still getting upgrades that don't include features from newer releases, and occasionally you learn that the functionality you crave does exist in the latest revision.

Win10 still clings to over 40% of devices weeks after Microsoft pulls support

I have a laptop that works perfectly well with Win10 and Linux (dual-boot). It won't run Win11 and I don't see why I should ditch a perfectly good laptop because of some arbitrary MS requirement, so no Windows 11 there.

I did discover that my main desktop machine, which runs Linux but is also not good enough for Win11, will actually run it in a VirtualBox VM. No doubt MS will break that at some point, but I did take a snapshot of the Win10 image before upgrading it, and I did take a snapshot of the working Win11 image once it was done, so hopefully I'll be able to keep something running. It only exists because I have one Windows-only piece of software I have to run once or twice a year and it's insisting on Win11 now.

Amazon spills plan to nuke Washington...with X-Energy mini-reactors

Re: More Micro than Small

If there's a decent market for the fuel then someone will invest in making it.

To me, as well as the tech and reg hurdles, what about physical security? You don't want some nut job (or group thereof) breaking in and doing bad things with the fuel, given that the rest of us would much prefer it to be kept in a safe, controlled environment. And what happens when they need to refuel the things? Something has to happen to the spent fuel, and that costs money that should really be properly planned for up-front rather than a vague "by the time we need it we'll have it figured out", which hasn't really worked too well so far.

End of Windows 10 support is the perfect time for the Windows 11 installer to fail

Re: Just learned?

It was never really relevant to me until I had a need for Win11 but not new hardware. I only really used the Win10 machine twice a year.

Some US tax software is requiring W11 starting with the 2025 edition (which we can't really use until 2026) on the basis that W10 will no longer be considered secure at that point. Whether it will actually still work on W10 remains to be seen. If they were smart they'd let it work with a big warning about security.

Isn't the presence of MBEC part of the definition of compliant hardware? My main PC was built in 2013 so it's definitely not going to support the newer features, but so far Linux runs just fine.

For me, the Win10 predecessor of my VM would be fired up twice a year, first to do updates, then again a bit later to do my US taxes. So I can put up with a lower performance because it's still the easiest/cheapest way to do that for me.

I learned this week that VirtualBox will allow Win11 to run on an old system in a VM. It will emulate TPM2.0. If you do a fresh install it seems to go quite happily, if you try to upgrade a Win10 installation it will object to the CPU variant, but a Google search will provide a registry hack to get past that stage.

I assume at some point Microsoft will break this, but for those who run Linux but keep a Windows VM around for that one program that isn't available on Linux, it's a way to keep going. Just take a snapshot before installing updates so you can revert to the last one before the breakage.

Trump admin says tech companies are abusing H-1B visas, slaps $100k a year to allow entry

I saw something go by late last night that needs more verification, that claims this fee is going to be retroactive and that anyone turning up at immigration with an H1B isn't going to be allowed in unless the fee payment is on their record, even if they've been living here for a while. The advice is that anyone on an H1B who's in the US stays in the US, and anyone with an H1B who's currently out of the country should get back before the rule kicks in. The advice also says that those on a derivative visa (H4?) should also do the same. It can certainly be read that way, and with the behaviour of the current US administration, assume the worst case.

Section 2(c):

(c) The Department of Homeland Security and the Department of State shall coordinate to take all necessary and appropriate action to implement this proclamation and to deny entry to the United States to any H-1B nonimmigrant for whom the prospective employer has not made the payment described in section 1 of this proclamation.

Microsoft insists Copilot+ PCs are 'empowering the future' – reality disagrees

No, their goal is to get it promoted to pilot, where it takes control of your life and you're just there to help.

Personally, any time I see anything to do with Copilot on my work PC (home machine is Linux), I search for how to disable it or otherwise make it go away.

Why blow up satellites when you can just hack them?

US signals intention to rethink job H-1B lottery

Re: There's a simple fix

If they're steadily raising the minimum then I would guess they're trying to implement something sensible over several years so as not to disrupt too much in the short term. Can't quite see government being that joined-up and forward-thinking though. They just went for a cheap headline and then it'll get filed.

I interpret that as "get way more benefits to reflect their contribution to the company performance" or similar. All that paid time off, decent and affordable healthcare, employment contracts, etc...

The actual skill level of H1B workers varies enormously, from "yes, we must encourage this person to come because it will benefit the US greatly" to "barely qualified and probably only here as a warm body to fill a seat and enrich some staffing agency by being paid a pittance while being contracted out at a much higher rate. To be fair, some of the latter category who manage to hang in there long enough do eventually learn if they've got people willing to coach them, but that's not really what the H1B is for.

In theory it's a valuable and useful programme, in practice it's been corrupted for the financial benefit of a few, often to the detriment of the people that really should get a visa but can't because the quota has been used up.

DHS warns of sharp rise in Chinese-made signal jammers it calls 'tools of terrorism'

Re: Don't panic people

The cell protocol has provision for priority, so what would happen is that the emergency comms would still get through, and no one else would be able to make calls. Still vulnerable to a jammer that blocks the entire cell tower though.

Having said that, there are directional antennas on most towers that try to radiate out towards the horizon in most cases, not straight down, so a jammer near a tower might not take out all of it, and would have to radiate sufficient power to overcome the antenna beam pattern that gives signals on the main lobe a significant advantage, which would probably make it fairly easy to track down. The main application for the sort of jammers in the article is to take out the handsets at the scene of the crime, not the tower. They can afford to be a lot lower power and cover a limited range.

"as lawmakers introduced new rules against vehicle key and key fob jammers as part of the Crime and Policing Bill."

The irony here is that many years ago they introduced a new frequency band for key fobs at 433MHz, which just happens to be in the middle of a popular amateur radio band, shared with the MOD. Documented cases of people parking near a radio tower and locking their car when the repeater on the tower was quiet, then coming back and being unable to unlock their car because the repeater was transmitting and effectively swamping the remote receiver. Didn't even need to be on the same frequency because of the cheap design of the fob receivers.

Techie traveled 4 hours to fix software that worked perfectly until a new hire used it

Re: I touch it and it breaks!

I was always good at breaking things too. It started at school with fellow students writing BASIC programs. "Enter a number from 1 to 5" was just inviting me to enter anything but, and they learned an awful lot about the importance of input validation from my actions.

The outstanding one was crashing the stuff written in Ada in my first proper job. It was trumpeted as being wonderful and rigorously tested etc. I was doing some testing on some aspect of the system and as part of it I had to navigate a page full of input parameters, which I filled in by alternating "0" and the enter key. I should note that this was on a VT220 terminal, to give some idea of the state of the UI. Having done this successfully numerous times, suddenly I got the thing to crash. The fully-validated input module took whatever input I'd given it and barfed. I mentally went through the muscle memory of what I'd just done and realised that I'd missed the 0 and hit the minus key next to it. This was an input it would accept because the number fields were for signed decimal numbers, but it turns out that having gotten past the initial input filter that took out all the characters that were not part of a number, what followed couldn't cope with a single minus sign as the entry because there was no numeric digit in the string. On a roll, I tried it with a + sign too, and got the same crash result. What a deeply satisfying day that was, breaking something that had passed all the required verification testing. And no, it's not one that had occurred to me before that day either, but you can be sure I've tried it on stuff ever since.

I got dragged from the West Country into London for a "feature" once. I was part of the dev team and it was escalated from the front-line support because they couldn't figure out the problem. So I turned up with one of the support guys who did the interface with the actual people and we went through a bunch of stuff and couldn't find anything wrong. We were literally on the way out the door having given up, when someone made a comment that provided the one piece of information that was missing. I remember we both knew exactly what was happening at that point and pivoted in unison to head for the control PC. It was doing exactly what it was supposed to, according to how it had been designed and configured, but they clearly needed a slightly different configuration.

Your graphics card's so fat, it's got its own gravity alert

Sometimes I'm glad I'm not a gamer or in need of that level of graphics performance. My current graphics card is ten years old and I'm only using it because I acquired a free second-hand machine (thanks, Windows 11) with one that was better than what I was using, albeit of similar vintage.

Windows 11 roadmap great for knowing what's coming next week. Not so good for next year

My roadmap for Windows 11 is to avoid it as much as possible. It's on my work PC but everything else runs Linux because none of my hardware is good enough for W11. So I get to avoid all the annoying features.

Re: hot plug

You'd be surprised. What is easy in the UK is way harder with the weedy US mains voltage. I have a high-velocity blower that allegedly[*] takes 10A (and is designed to be a bit inefficient as the airflow runs over the motor and so comes out slightly heated for fur-drying purposes). The plug and cord on that get a bit warm when I use it for long enough. It would be pulling half the current and a quarter of the heating effect if it was a 230V device.

[*] I think it takes more than that, based on the size of generator needed to power it reliably.

Microsoft trims more CPUs from Windows 11 compatibility list

Re: Goodbye Windows 11

The only thing I "need" Windows for is the tax returns software. While the vendor is willing to let it run on Windows 10 (they may lose a lot of their market if not) I can cope by running my Windows 10 VM, which only tends to get fired up to do taxes. If not, I'll find another way to file taxes, even if I have to resort to a paper filing.

This is partly why I've always built new machines from parts. I'm not aware that they get kickbacks at that level (and I hope not), and given that I've always installed Linux, it meant I could avoid the Windows tax. My laptop (too old for Win11) did come with Win10 and I have subsequently acquired a Pro licence which is used when I dual-boot, but the disk I/O is painfully slow compared to what I get from Linux, so between manufacturer and MS, they screwed that up too.

My newest desktop machine is now over 11 years old and is still going strong, albeit with a few upgrades. Running Mint22 with KDE on top and copes perfectly well.

I put up a post with distrowatch,com in it and it's still there six hours later.

Then again, I've had the bot take offence to something I posted a year earlier (and which I'd later set to viewable by only me) so it may just mean it's busy elsewhere.

Microsoft declares 2025 'the year of the Windows 11 PC refresh'

The Windows shop is going to keep hyping Windows 11 and trying to sell the public on its AI OS vision, whether customers like it or not.

A lot of customers don't have a choice. Some of the tools I need for work are only available on Windows, which is why my work PC is new enough to run Windows 11. However, it lives on my desk next to my Linux machine which does pretty much everything I need it to for my use.
