Generally when you are on strike you do not get paid.

A tenth is perhaps an exaggeration. It depends on how you count your lifespan.

A lead-acid battery mainly ages by cycle count. If you keep a decent quality battery charged up, and don't regularly discharge it too much, then there are claims they will last ten years. If you discharge them excessively each day, then you'll kill them really quickly.

A LiFePO4 battery has a quoted cycle count. But really what matters is simply elapsed time - the battery will last about ten years if it isn't abused, and you'll be hard-pressed to actually do that many cycles in that ten years. It ages mainly by elapsed time, not cycle count.

I used to argue that for an off-grid solar solution, you should get lead-acid batteries with capacity so that you are normally never discharging below 70%, and that this was still cheaper than getting LiFePO4 batteries with smaller capacity that you would discharge down to 20% each night. The lead-acid would then give you a larger reserve capacity for those instances where the weather is foul for a bit longer than normal and you don't get meaningful charging.

However, since then LiFePO4 batteries have continued to decrease in price, there are new Sodium batteries available now, and I haven't done the calculations again - the best option may have switched over, or it may be so close that it doesn't really matter which one you choose.

I have a completely unrelated problem with my rather old Asus Zenbook UX305C. The Intel graphics driver for Linux (specifically Debian) crashes the whole OS whenever it enters DPMS screen blanking. I'm able to tell the interface while logged in to never blank, but the login/unlock screen use a completely separate X server with separate settings, and I haven't been able to work out how to just completely disable DPMS. So while it can sleep and suspend, I can never lock the screen, and when I wake it from sleep/suspend I cannot leave the login screen long enough for it to go into screensaver, because that will crash the computer.

It's annoying. Back in the mists of time when the laptop was new, it all worked fine. It's the updated Intel drivers that are broken.

When I go hiking for a couple of weeks (with significant elevation gain each day), I eat like a pig. I mean, something like 5000 calories a day. I lose weight over that time. So it's possible to lose weight through exercise, however you really do have to spend a very significant chunk of each day doing it for it to work.

Not eating as much takes much less of your busy day.

Is this page geo-locked? All I get is a page telling me that I'm unauthorised to view the page.

I work with monogenic diseases, where a single mutation (or a pair in the same gene for recessive conditions) does cause disease. There's a lot of them. Your statement isn't true for these.

You're talking about polygenic traits. That's a different ball game entirely.

That's not universal. I work in genetics, and we did an investigation a few months back, by asking various AIs whether a particular mutation causes $DISEASE. Invariably they were very strongly biased towards saying yes, even for completely obviously benign variants. I think that's because the majority of the literature out there describing variants is describing pathogenic ones, because why would you write an article about a benign variant, so the only material it has ingested is articles describing variants as pathogenic. In reality, the average person has millions of variants, and almost all of them are completely benign, so there should be a very strong pre-supposition that a given variant is benign unless there is fairly strong evidence saying otherwise.

It's helped a lot by the fact that solar panels have become very cheap indeed, so the fact that we don't get as much sun as other places doesn't matter so much - it will still pay off, as long as you can actually use that energy effectively (which may require batteries or a decent export payment rate).

Astronomers definitely do like them because they're orange, and they can filter it out of their photos.

The typical wording is "We value your privacy". Which just means they think it's valuable and want a part of that pie thank you very much.

Any fule no that a file name is just an array of bytes (excluding the null byte and the slash). You can create a file with a name that is an invalid UTF-8 encoding. It's fun to see how much software chokes on that!

In every single directory you're ever going to have as cwd when running that software?

It's not the PNG encoding that causes the loss. The optimisers are literally creating a different image and then losslessly encoding it as PNG.

But it's also a valid point.

Some explosives degrade by becoming more and more sensitive and dangerous, not less.
