Can't comment on a thermal collector, but if we look at efficiency of solar PV and heat pumps: Solar PV panel: the best ones are up to about 22% efficiency. Heat pumps: again, top of the line approaches 400% You can't just multipl

Keeping strength up, especially in old age, is crucial. My father was admitted to hospital for something, and spent a few weeks on the ward. When he was released he was super frail and had to use a walker. Losing strength is easy, getting i

The change from NEM 2 to NEM 3 makes getting solar without a battery pointless - so looks like stored demand shifting.

Interesting, as aspirin is an anti-inflammatory - there's also a super small scale trial that happened in Madrid where a short course of 30mg of predisone had positive impact on those suffering from long-covid.

This feels like the adage of marginal gains. Any one change by itself is small, but they compound. Used successfully by british cycling, I wonder if this would be similar?

Is it not fairer to say that Orwell was not a fan of totalitarianism of any form?

Not sure about Denmark, but in the UK part of the MCS signoff to allow you to export to the grid and receive payments is fitting of an generation meter. It's a holdover from the old FIT days (because you were paid per kWh generated), a

You see them far more than Solar PV in Denmark as well, because IIRC you get taxed per kWh consumed, no matter where it's generated, so it's more economical to use the roof space for domestic hot water instead.

SEO consultants, yes, there are some snake-oil salespeople. Most of the big travel sites have in-house SEO teams, who do A/B experiments, have entire frameworks for quickly rolling out changes to things like page titles, subheadings et

Xerox is the way to go - I got a VersaLink c405 at the start of the pandemic - it's not cheap, but no rubbish in the drivers, accepts third party toner without complaint and most parts are serviceable.

Why use active splitters when it's much cheaper to install passive ones?

indeed I do. I meant rolling out solar.

Isn't China massively rolling out China and nuclear as well? It feels like their coal usage is bridging, rather than permanent.

I mean, it probably helps that a large % of the software they ship as part of Ubuntu is upstream, Kernel, Window Manager, Utils etc. etc. The better metric would be how many people does Apple have working on Darwin/iOS/MacOS/

True. In the case of my current gig, that's not an issue as there is a huge organisation supporting that and live services.

The other option is provisioning dev servers as VMs on big hosts, which some other companies do. That’s where the build and development happens, using an IDE locally on the issued laptop which uses remoting.

Most don't use the naive way to scan for images, NCMEC distributes hashes as PhotoDNA which is a perceptual, not a cryptographic, hash, which is tolerant to some level of changes.

Nope. Plenty of people use iMessage in the UK, facetime as well.

That's just for the interface layer though.

by philjohn 3y ago
To be fair, with libraries the API layer can be essentially zero code, and with type checking. That's how it worked when I was at my previous gig.

About the only "successful" privatisation in the UK was of telecoms. The main infrastructure company that operates country wide (OpenReach) are heavily regulated by how much they can charge for last mile termination. So that means

In a past job, the benefit of microservices was that some of the operations performed by the system were fare more CPU intensive than others - by having them in their own service that could be scaled independently led to lower overall hardw

The UK has one player, Octopus Energy, who offers innovative tariffs. Their SEG (feed in tariff) rates are also about 3x higher than anyone else offers. You can either go for a flat rate of 15p per kWh, or go on their flex tariff where your

That makes me feel old. I was running FreeBSD back when that split happened, I can't believe it's been 20 years. I think the BSD ecosystem was harmed more by the SCO lawsuit, and the rise of Linux than by the Dragonfly/FreeBS
