The UK gas network was used for many decades to transport a 50-50 mix of hydrogen and CO, called "town gas". Nevertheless the risk to the modern network should be diligently evaluated . I believe the intention is to do that anyway

by ajb 2y ago
The funny thing is that theoretically hydrogen would be easy to deploy in the UK. We already have a gas network for methane, it wouldn't be hard to mix in 20% hydrogen and then filter it back out at the other end (there's an ener

Anyone wondering why you'd need a linker script: They are essential on bare metal, as you have to tell the linker where the hardware requires you to put stuff. There are lots in the linux kernel repo, u-boot, probably Arduino, etc.

Certainly no intention to be negative. Not having run the numbers, I don't know if the older ones got slower over time due to more features, or the new ones are squeezing out new performance gains. I guess it's also partly that

Given that it's a DB under the hood, we really need some new terminology to understand what's happening when there's a disc format change. I think that some of these format changes are in fact schema changes, which makes the

If you don't do age verification then your need to comply with COPPA etc as you have to assume underage users. My previous employer used twohat to monitor for content dangerous to underage users, but I don't know if they were any

It's only been in the upstream kernel 6 months or so? I know the FS has actually been around longer, but I've not heard claims about it's stability before that. It's only now that's it's getting a lot more test

I should not have implied that every bug report would be a bad interaction - and to be fair where I've seen it degenerate in the mailing list, it's often the other person wasn't exactly civil to start with (which unfortunate

Yeah I assume that's what "the Rust team" meant

His side is that basically it doesn't make sense to package the tools for an experimental FS in an OS that's going to get very far behind, as debian stable will do, since the tools have to iterate rapidly to fix problems with rele

Bcachefs is experimental, and last I heard, the authors hope to be able to declare it not experimental in ~6 months. To me, that's 'try on a cache server/build server' territory, not on anything where you even think abou

Guy knows his audience though. All of his posts are incredibly prone to bikeshedding. If our main journalists knew that their output was going to be subject to much detail-oriented scrutiny, we'd have the best-run country in the world.

From the vantage point of Cambridge it has a reputation as a shithole, but I haven't been there either so would also like to know. The county council covering the Cambridge area is actually based in Peterborough, and so effectively con

They made a bad bet on the structure of their designs. They were bought by SoftBank last year; they have a new design in the works, but might have trouble delivering it as apparently there's been a bit of a talent exodus. There are sev

One thing to bear in mind, if anyone feels like trying out this old stuff, is that modems relied on the latency being absolutely fixed; as was guaranteed in the POTS network - and of course an analogue connection. Modern VoIP calling does n

Amazing stuff. I wonder what hardware you need to try it out.

by ajb 2y ago
If you're near a branch you can also just pop in and ask for one; might be faster. I did that when the battery ran out on my last one. There's no process upfront, you then have to pair it with your account. Well,you will probably

This can be done in software, eg https://askubuntu.com/questions/31580/is-there-a-way-of-leve... for linux. I guess that you're asking for hardware because the source device is not under your control. In theo

You could try getting them to give you a physical security key, they used to supply them and I think still will if you can't use the app (just say it doesn't work on your phone). I have one and the website still works with it.

Ah thanks, I missed that somehow.

This doesn't explain why the website can't just validate the input, queue up the transaction, and execute it later when the dB is available. It's not like your record changes that often. If the transaction fails they can then

Normally yes. But they're using a whole wafer for a single chip! So it's actually a good idea. I guess the issue is how do you design your routing fabric to work in the edge regions. Actually I wonder how they are exposing this wa

by ajb 2y ago
Good question. I think the wafer has a cost per area which is fairly significant, but I don't have any figures. There has historically been a push to utilise them more efficiently, eg by building fabs that can process larger wafers. Al

by ajb 2y ago
So they massively reduce the area lost to defects per wafer, from 361 to 2.2 square mm. But from the figures in this blog, this is massively outweighed by the fact that they only get 46222 sq mm useable area out of the wafer, as opposed to

Amusingly this is true of an older discovery that now seems very commonplace: vibration, around the time that scientists understood the simple harmonic oscillator, and the fact that the same mathematics applies to lots of things from sounds
