alextingle··on How I stopped worrying and loved Makefiles
This is better achieved with the compiler level tooling, rather than in Make. It's pretty easy to replace `cc` with a short script that runs the pre-compiler and compares the result with a cache.

If the source code is kept tight, it doesn't yield much of a speed-up, though - precompiling hundreds of unnecessary headers can take a lot of time. Better to put some effort into moving unnecessary #includes out of header files. In fact, you can use your log of cache-hits to guide that work.

alextingle··on Google made me ruin a perfectly good website (2023)
lol. "Cups"... No serious recipes there.
alextingle··on Unicomp's "New" Model M Keyboard
Unicomp's customer service was absolutely terrible when I bought from them. I ordered a black keyboard. They spent ages doing nothing. When I complained, they finally shipped me... a beige keyboard.

When I notified them, the rep said (and I quote), "I don't really see the problem... can't you use it as is?"

He refused to replace it, and reluctantly refunded me the purchase price (but not the extremely expensive postage). So if I wanted to get what I actually ordered, I'd have had to start the whole tortuous process from scratch, and still be out of pocket.

The whole experience was ridiculous.

alextingle··on Use Plaintext Email (2019)
I have my mail client set to show me only plain text. I only ever send plain text.

Every so often I receive a badly formed e-mail that requires me to click a single button that shows me the rich text.

There's no drama. I communicate just fine.

alextingle··on Brace yourself, IPv6 is coming
I was expecting this article to be from 2010 or something.
alextingle··on How governments become addicted to suppliers like Fujitsu
Wow. What an evidence-free hot take.

So, is _The Register_ "upper class", while sub-postmasters are "ordinary people"? Are Post Office managers "upper class"? I'm pretty sure it's not one of the main careers for old Etonians. Is Fujitsu "foreign", even though its business in the UK is mainly just the old, British, ICL.

Were any "cents" stolen? I suppose it's possible, since Post Offices do deal in foreign currency transactions.

It there's any actual substance, can you explain it with a few sources, please?

alextingle··on Spot the bug in this Python code (2023)
If you need to explain how your clever clever Python code works, you're doing it wrong.
alextingle··on The Curious Case of MD5
It's broken for hashing too.

The point is that MD5 is no good if there's any way an adversary might want to subvert it. It's fine if you just want to use it for hashing your own documents, but as soon as there's an incentive for someone to substitute one document for another, MD5 is problematic.

That's certainly the case for encryption, but it's also the case for these legal document records.

alextingle··on Compare Google, Bing, Marginalia, Kagi, Mwmbl, and ChatGPT
claude.ai produced pretty reasonable results.
alextingle··on Firefox on the brink?
Another FF user here. Very, very few issues.

I had a problem with a shopping web-site the other day. I disabled uBlock origin, and then all extensions, but it still refused to work. I thought I'd finally found one of these mythical "Chrome-only" sites, but no - exactly the same broken site in Chrome, so the site was just totally broken. Nothing to do with FF.

You really have no idea what you're talking about, do you?

alextingle··on Can solar and wind power Britain? An update of David MacKay's numbers
This article is extremely disingenuous about MacKay's "arguments against" section. In reality, he was pointing out the objections that might be raised against renewable projects, in a tongue-in-cheek manner.

His graphic where >95% of potential renewables are crossed out because of various ridiculous NIMBY arguments is meant to make a point about the practical problems of delivering large projects. It's not a serious prediction... for that, you need to look later in the book, at the sections the author conveniently ignored.

alextingle··on Can solar and wind power Britain? An update of David MacKay's numbers
The book is about the UK, not the US.

The UK has much, much less solar potential than the US. The southern most point of Great Britain is further north than the northern most point of the contiguous USA. And it's really, really rainy here too.

alextingle··on They Cracked the Code to a Locked USB Drive Worth $235M in Bitcoin
Is it reasonable for Stefan Thomas to get half of the total?

What does game theory say is the optimum split between two parties like this, who individually have nothing, but can work together to unlock a vast fortune?

alextingle··on The game theory of the Republican speakership crisis
No. He's exactly right.
alextingle··on The game theory of the Republican speakership crisis
They are a tiny minority. It makes no sense for them to have any influence whatsoever.

They are not really the problem. The problem is that your institutions offer no mechanism for a majority that agrees on a particular course of action to actually make it happen. Silly partisanship trumps running the country.

Perhaps you need to consider secret ballots in your legislature. That would eliminate partisanship in a trice.

So you fired your testing team, and replaced them with your users. Do the users get paid for that work?
alextingle··on Design IoT Dashboards with MQTT Studio: Quick and Easy Visualization
Looks very nice.

It's not clear what this actually is. Does it generate a Javascript app that does all the work in the browser? Does it have a server-side component?

Which host actually establishes the MQTT connection?

Can it only talk to MQTT servers that are publicly available on the Internet?

alextingle··on Version 5 of systemd-free Debian remix Devuan is here
I wish we could have a systemd that JUST does the job of init, and leaves the system logging, DNS resolving, etc. to the prexisting software that does a better job of it.
alextingle··on The fall of Stack Overflow, explained?
Love the punchline at the end.
alextingle··on 'Breakthrough' geothermal tech produces 3.5 megawatts of carbon-free power
They specified a conversion rate of 1 MW : 750 "homes". So if the Utah project can power 750 "homes", that's 400 MW.
alextingle··on Firefox address bar
Now can they fix the URLbar so that focussing it doesn't weirdly select all. So frustrating when I want to edit a URL.

That is a legit useful tip. Thanks.
alextingle··on Life before cellphones: The after-work activities of young people in 2002
> The trick, of course, is to get a new, better job at a different company.

That's all very well, but if you continue to fail to set expectations at your new company, then the cycle will just continue.

alextingle··on Filenames and pathnames in shell: How to do it correctly (2020)
> People are making things more complex than they are.

You are the one who wants to introduce extra complexity: A few narrow corner cases where the filesystem treats certain code-points as equivalent. Imagine how confusing that would be to someone who doesn't regularly use those code-points.

alextingle··on Controlling the nuclear fusion plasma in a tokamak with reinforcement learning
Direct harvesting is not possible with the fusion reactions we are currently working on. The products are electrically neutral, so the only way to harvest the energy is as heat.

Helium-3 fusion produces charged particles, which it might be possible to directly harvest as electricity. The He3 fusion reaction has a high activation energy, which is currently unachievable, and there is no Helium-3 on Earth. We'd have to get it from space, somehow. (The movie "Moon" was set on a Helium-3 mining outpost on the Moon.)

They do divide opinion. I never use my trackpad, and always just use the trackpoint.
alextingle··on We’re Never Going to Mine the Asteroid Belt
Stripped of the hyperbole, the article merely points out that space mining will only be profitable if the exercise is largely self-sufficient. If every piece of equipment needs to be launched from Earth's surface, then it's going to be very tough to make it profitable. I don't think the space mining start-ups he's so dismissive of were in any doubt about that.

His fictional example of "Moon" is illustrative. That film was set in a Helium-3 mining facility. Helium-3 simply doesn't exist on Earth. If we get to the point where we need it to power our advanced fusion reactors, then we'll have no alternative but to create a space-based mining industry. Once the infrastructure is in place for that, then lots of other space-mining opportunities will start to look tempting too.

alextingle··on Grenfell Tower inquiry: key things we’ve learned this year
Technically, a leasehold is a very, very long fixed-term rental tenancy, with a single up-front payment. The tenancy is freely transferable, so there is a market for leaseholds that resembles the property market for freeholds. (A freehold is where the property is owned outright.)

In practice, leaseholds are mainly used to apportion "ownership" within buildings such as apartment blocks, where simple ownership of the land does not sufficiently capture the complexity of the situation.

Problems arise in a number of areas:

First and foremost, leaseholds resemble property ownership, and so many people naively treat them as such. But the value of a lease decreases as time goes by. When only a few years remain, the value drops very quickly. People who are unprepared for this can get a nasty shock, and feel hard done by.

Secondly, and more subtly, the leasehold creates a complex relationship between the landlord and the tenant - just like any rental agreement. The terms are set out in a contract which is specific to that particular leasehold - so they may vary greatly one from another. There are a myriad ways that they can contain unfair clauses, or unexpected terms.

One recent scam is for landlords to create leases that have a small, annual "service charge" (payable to the landlord) whose cost doubles every few years. After a while, the payments become extortionate!

In this case, the landlord is allowed to charge tenants for the cost of some kinds of works to the building. In the lease, that probably looks like a small item, but a clever landlord can specify the works in such a way that the tenants shoulder most, or all of the cost.
