Re: 99.98 accuracy

Sounds more accurate than their pricing was when I shopped there 20 years ago. Invariably every time I went, there would be at least 1 item that didn't match the shelf price at checkout. Staff couldn't care less.

Re: The last thing we want

Nvidia are free to offer binary blobs that compile (within reason) with any kernel, alternatively they can provide a pre-built module that works with a very limited set of kernels. I expect they do the first, in which case you need somebody who can update the Nvidia sources which support later kernels to add back in the necessary support for older cards - caveat being they haven't also pulled support from the blob (which they probably did) in which case you're at a dead end.

You're also free to buy AMD cards which have better in-kernel support, but assuming you already shelled out your cash to Nvidia then the Nouveau driver provides support for cards Nvidia has disowned.

Re: DuckDuckGo

Have to say I installed Vivaldi on the phone a couple of months ago (phone being a device I use only when I don't have my laptop nearby, which is rare). Didn't notice immediately that the default search was startpage but did notice that the relevant search results took some scrolling to get to with the first results being (can't remember what they were) something I didn't want. Being lazy I continued with startpage and continued noticing the irrelevant results and only this week got round to changing the search to google whereby normal search resumed.

Starlink tells the world it has over 150 sextillion IPv6 addresses

Re: Talking telephone numbers

Which part of IPv4 allows for country codes?

Oh that's right, none so you'll need IPv4.1 which is 100% not backwards compatible with IPv4. OK so a country code + IPv4 would be simpler to remember than a 128 bit number, so all you've done is add another byte to the address making a not very round 40 bit length. But dividing by country isn't very efficient, compare say Lichtenstein with China.

There is truth they could have simply added a byte or two to make an incompatible IPv4.x, but if you're going to break everything then why not start from scratch and try and design something functionally better?

Re: HMRC Down

Funny that, your favourite BBB used to be my favourite BBB when he was creating videos about, well, barrister related stuff. Then he realised there's money to be made pandering to a certain section of the population who seem, how to say, anti-establishment (not sure I'm using that correctly, but hey). Then he started pumping out daily videos about nothing much, filled with sponsored segments.

Similar to how the venerable Dr (PhD) John Campbell was giving sound advice at the beginning of the pandemic, then again realised where the real money is to be made with his wink winks, and threw all the published science to the side and misinterpreted plenty of non-sensical fringe-science.

Anyway enough of reviewing YouTubers. So BBB is scared that it's outsourced to Romania, a country which adheres to GDPR legislation. When does BBB know the first thing about outsourcing and IT? Sure he knows law, he's a black belt, but no mention of being anything related to IT.

The alternative is to not outsource it and keep it all in house - back to my last statement, the government is hardly competent when it comes to IT (well perhaps a lot more than IT but I digress). So how would keeping it in house be better. Is there any information who this Romanian outfit are? Do they have a bespoke authentication product that's used by other companies/countries? Are they just some guys bedroom PC? More information would be good before one starts speculating about insecurity, but BBB is best when there's no actual information and plenty of speculation.

Re: HMRC Down

Well if Bob enrols Alice's biometrics on his device, or shares his passcode with Alice then sure Alice can pretend to be Bob if Alice has Bob's device. Is Alice Bob's mum, you didn't specify?

Meanwhile when Balaclava Boy swipes Bob's unlocked phone, the digital ID app still requires the same biometrics to be opened so Balaclava Boy is unable to identify as Bob.

Re: HMRC Down

As for ID theft, that will be rather harder with a digital ID. The process of acquiring a digital ID should be secure enough that should a re-application come in for the same person, then flags will be raised requiring further verification.

As opposed to today where you can whip up a fake ID, some fake bank statements, fake utility bills and hey presto you now have credit in the name of Bob.

Solviva

Re: HMRC Down

"like why aren't passports or driving licences secure enough"

Ask country X why their passports are easy to forge. Not everybody is eligible for a driving license.

The thing with (a properly implemented) digital ID is that it is simply an authentication mechanism, in this case run by UK.gov. As much as it would be possible to log when and where said ID has been used (and it would make sense to do that, whereby you yourself can view your history), that's the most that should be done by UK.gov. It's up to whatever organisation wants to participate in digital ID to perform authorisation on whether they allow digital Bob to use their services or not, the government simply provides verification that digital Bob really does represent real Bob.

Solviva

Re: HMRC Down

Well you've proved the point, Digital ID will make zero difference to how you access your money today (which sounds like you go outside and visit physical branches or cash machines).

Digital ID is unlikely to be used for getting cash out (although it could be used to verify you are the card holder rather than entering a PIN). It's just another way of identifying yourself, supposedly more secure than a passport or driving license.

Solviva

Re: HMRC Down

That's exactly my point, that which works now without digital ID won't suddenly stop working or degrade if/when Digital ID arrives. The nay sayers that jumped on Kier's "make it easier to access your money" seem to have turned this into it somehow would be harder to access your money without Digital ID (if/whenit exists) - well yes comparatively, but no harder than it would be today.

Solviva

Re: HMRC Down

Might or might not do, but everything you can do now without Digital ID would still be do-able (or not thanks to AWS).

Re: An Age Thing

And that's how the 'Internet' works today.

Re: Why is it so insecure?

Not a bad idea. My thoughts are to essentially measure roughly the RTT. Difference between half a metre and 20m should be easy enough to detect. Communicate with the key to set up a pre-configured encrypted 'ping' packet which the key loads into its transmit buffer, then the car says 'go' and counts the ticks till the reply is received.

The exponential 'blocked' would be a nice DOS, unless you still get a physical key to open at least one door.

Apartment living to get worse in 5 years as 6 GHz Wi-Fi nears ‘exhaustion’

Isn't this a use case where 60 GHz would shine? It's attenuated by almost everything so no issues with noisy neighbours, the only downside is you'll need a AP in every room and as such new builds should be designed with a comms cabinet in each flat that features CAT6/7 to every room*.

New SSL/TLS certs to each live no longer than 47 days by 2029

Re: Why not...

When I was a rather fresh sysadmin I got asked to install a local Kerberos/LDAP login system for a few Linux machines. This involved generating certificates and keys and whatnot... I set the certificate age to 10 years and thinking that was about 35% of my current lifetime it would be good forever (ahem *cough* 10 years). Cue a few years back suddenly reports of logins not working, which seemed weird as I hadn't changed anything lately. After a bit of debugging it became apparent a certain 10 year certificate had expired - cue grasping around for my notes to make a new certificate. Except this time I've set the expiry shorter, made better notes and aim to refresh the certificate annually so as to have the procedure 'fresh'. So yes, shorter certificates get my vote.

Whilst true, my very basic knowledge of gases is that whilst helium is incredibly slippery and escapes almost anything, the point of the helium being there in the first place is it offers lower resistance to the spinning platters compared to regular air. Once the helium leaves, it's going to be a vacuum assuming the drives are sufficiently sealed to not let anything else in - but would helium really want to leave an area of lower pressure (the now leaking drive) to migrate to a higher pressure? That's not what gasses like to do.

Re: If you're pushing data out 100 GbE ethernet interfaces

You can flood a 100 GbE interface with a single core, but this requires kernel bypass techniques - DPDK or libVMA to name a couple. At high packet rates the context switching between userspace and kernel is a significant overhead which these schemes avoid, with various disadvantages on the way so they aren't completely plug in replacements.

Wonder how this compares to good old interrupt moderation? Sounds like a similar idea - instead of interrupting on every interrupt, wait for either X interrupts before the application is interrupted (heavy traffic) else if Y time has passed since it was last interrupted (light traffic) fire an interrupt.

Ahh sometime in the early 90s my dad had a jar of coffee in his cubicle. Over time he was suspicious that there seemed to be less coffee in it when he opened it in the morning than there was the last time he closed it the previous day. Not one to let the mystery continue unsolved he placed his camcorder somewhere out of sight, with a view of his coffee jar and left it recording one evening after he left.

Mystery solved, it was the cleaner that done it!

AMD reverses course: Ryzen 3000 CPUs will get SinkClose patch after all

Solviva

I've got a few AMD systems at work, Threadripper and Epyc. From investigating this it seems the Epyc chips have patched microcode available now for Linux which can be loaded via the kernel at boot. Anything not Epyc needs to come in the form of a new BIOS. Thus it's all well and good AMD supporting the 3000 series with a patch, but how many manufacturers are going to have a BIOS update for this?

Does Windows fair any better in getting microcode updates for the non Epyc chips?

As of now, Supermicro have no recent BIOS updates for my AMD systems.

Julian Assange pleads guilty, leaves courtroom a free man

Solviva

If it was so water tight, why was he not detained when he asked wether he was OK to leave Sweden? The simplest option would have been to say you can't leave Sweden, and if he left he would then have an arrest warrant served for leaving when not allowed. That's not what happened though as they clearly said he was free to leave.

Re: "certain types of journalism won't be tolerated"

Better go look at the facts before telling a good story. He was questioned whilst in Sweden and asked whether it was OK for him to leave Sweden, to which he was told that was fine. He left, as per his pre-scheduled plans. Sometime later the Swedish prosecutor decided she wanted to formally interview him and so issued an arrest warrant at which point Assange moved in to the embassy.

Re: I am SO happy to have a classical speedometer

My 2013 V40 has a digital instrument display, and smallish (it's the larger option) infotainment display. I've set my infotainment to show the speed in the corner, and I guess it's more a me thing (takes a long time for me to read an analogue clock such that the time one processed is no longer valid :) but I always glance at the infotainment for the speed and ignore the actual speedo.

When I first heard about this I thought "so what", assuming the instrument display existed, but discovering that IS the instrument display, well like most people I hate touch screens in cars with dynamic menus and screens. If I want the volume up or down, there's a button or knob that does that job and that job only. For heating, cooling the same, no need to look where my hand is, my hand goes roughly the right place and can feel to get the correct button. Try that on a touch screen.

Indeed who actually designs these things? (I should ask some of my former colleagues that defected to Volvo...).

Re: Financially viable?

Which really is borderline insane - shellfish are fished in (e.g. European waters), shipped to china to be deshelled with cheap labour, to be shipped back to the origin as that's cheaper than simply deshelling at origin. Point being labour in China can be stupidly cheap, so these cheap labourers go the fun way of burning the wires rather than stripping by hand. Well I guess not insane, simply good economics in accordance with the local environmental policy.

Meanwhile in the EU we've got to suffer plastic caps that stay attached when unscrewed because apparently the separate caps seem to always end up in the sea (isn't that always the argument, plastic bags... everything ends in the sea).

NT worked fine with 4 MB after removing these...

Apple swipes left on the last Touch Bar Mac, replaces it with a pricier 14″ model

Re: Ports, baby, ports!

Thankfully the M1 MBP series re-introduced all the ports that Apple locked away in the safe since I think 2016 or 2017, and ditched the touchbar. They also, oddly, fattened them up too, such that physically it's almost identical to the 2012 - even the ports, with the exception of no thunderbolt & USB-A, instead just 3 USB-C. It really was a happy accident my 2019 MBP didn't take kindly to imbibing honey sweetened coffee in November 2021... The only downside was the lead time for the M1 ended up being over 4 months, so it was back to the 2012 with the decaying screen coating (that being the 4th replacement screen for that issue).

Not a fanboy here but with the processor you're not comparing oranges to Oranges.

Last year's 14/14 plus had an A15. This year's 15/15 plus has an A16. So yes the A16 is a year old, but then it's a year newer than that in the 14/14 plus. If you want this year's processor you need to go to the pro models. If you went from a 14 to 15 pro, you'd be advancing 2 generations.

Sure they could put the same processor in the standard and pro phones and differentiate them in other ways, but they choose to give the non-pro phones last year's pro processor, which is almost certainly why the non pro 15s still have USB2, as that's what lightning is.
