It's not a binary choice. Independent boffin builds a ternary CPU on an FPGA

Re: ternary?

From a purely theoretical point of view, the most information-dense number base would be "e" (2.78128etc.)

Lot of people round here have read Knuth's TAoCP (not surprisingly).

Re: Confused Old Bunny Here!

the Turing Machine was a thought experiment involving "tokens" on an infinitely long rolls of paper tape, as I recall.

The tape merely has to be long enough, as all computations that halt have a finite number of steps. You can even do the CS theoretical equivalent of paging - if you're about to move off the end of the tape, suspend operation until you've spliced more tape on the end and then resume.

In my experience it's more "Fuck! Is it Friday already? Where'd the week go??"

GhostBSD to ditch Xorg for XLibre as Red Hat's Wayland crusade leaves X11 fans out in the cold

Arthur the cat

Re: I've been using Wayland on FreeBSD for over a year, but some things are still an issue

[1] This admittedly was a huge pain. Maybe on Linux users multiple monitors are fine, but I wasted a couple of hours fiddling with xorg.conf which crucially needed multiple Option "Monitor-<connector>" sections under Device, Monitor sections with LeftOf and RightOf, a ModeLine and crucially an Option "PreferredMode" (which I missed several times). This is one thing I didn't need to mess around with under Wayland.

I have a single huge monitor so no experience with configuring multiple ones, but isn't that all supposed to be done with xrandr these days? (I won't bother with a redundant "correct me if I'm wrong".)

Anthropic's Claude Opus 4.6 spends $20K trying to write a C compiler

Arthur the cat
FAIL

Linux kernel compiled *but wouldn't link*

Read this article comparing CCC with GCC.

The Claude C compiler could compile the kernel but linking failed. It did compile and link SQLite but the CCC built version took 2 hours 6 minutes to run a benchmark that a GCC built version did in 10.3 seconds.

It's undoubtedly some sort of brilliant feat for AI, but in terms of real world utility it's up there with chocolate teapots and fishnet condoms.

DWP finds Copilot saves civil servants a whopping 19 minutes a day

Arthur the cat

Re: Costly placebo

First, 19 minutes a day is not productivity. It is noise. You could claw back more than that by [various sane suggestions]

A friend of mine used to work for DWP when he started in the civil service. The sign on process was so inefficient he used to turn on his computer and sign in the moment he got into the office, then take off his coat, go get a cup of coffee, chat with colleagues, and generally waste time, and finally after 30-35 minutes the sign on would finish and he'd be able to get on with work. Just fixing that would have got a greater improvement.

Re: the systemd ecosystem

Whatever happened to "do one thing and do it well"?

Discarded as old fashioned. The new fashion is try to do everyhing, fail regularly, brick the machine occasionally and claim AI will solve all the problems which is why you're forcing it on everybody even if they don't want it.

Re: Hmmm...

It is definitely a barrier to entry for any new player creating a new product that's required to follow GDPR.

It's a relatively low barrier, basically it's "be competent, don't be a shyster".

My wife has far more problems dealing with commercial confidentiality restrictions in her work than GDPR. They can involve insane levels of paranoia and hoop jumping.

Re: Accessibility – not just a good idea, it's the law

When was the last time you every heard of anyone being PROSECUTED for their shitty websites that break screen readers and assistive apps to fill in webforms ????

Policy suggestion for any party that wants it: Rather than prosecute such websites and get a pitiful fine, for a reasonably small donation to HMRC the web site owner and designer are thrashed to within an inch of their lives. Repeated prosecutions are allowed for the same web site if it hasn't improved within a month.

UNIX V4 tape successfully recovered: First ever version of UNIX written in C is running again

Arthur the cat

Re: /usr

My understanding is that Unix “dd” was named, and given its obscure syntax, as a joke, an allusion to the IBM OS/360 JCL command DD (define dataset)

My understanding is much the same, except that it wasn't a joke, the original author actually liked JCL's DD. (Ack! Spit!) I heard that 45 years ago when I asked the friend introducing me to Unix V6 why dd was such a non-standard command..

The GNU project, meanwhile, had written most of an OS except the kernel. It considered using the BSD kernel but foolishly changed its mind and decided to write its own.

Re: early DOS developers

Shame they got \ and / mixed up.

Early DOS didn't have subdirectories and '/' was used to indicate command flags (as in DIR /W), so when subdirectories were introduced they chose '\' for command line stuff as being similar to Unix's path separator. The DOS internal file systems routines would happily accept forward slashes as path separators as well as backslashes.

This is why no stakeholder actually said "WTF???" and everyone went on with this idiocy.

Quite a few stockholders did say "WTF?" and "No Way!" as well, the Norwegian Sovereign Fund being one, but in total they amounted to only 25% of the stock holding.

Re: Password rules make for weaker passwords

Make the password requirements onerous, demand frequent changes and you may as well say "Write the current version on a Post-It note and stick it on your monitor".

I'm far more security conscious than that - I stick the Post-it note under the monitor base.

Re: Experience is the core of understanding

This is an area that would provide fertile ground for near-term sci fi storytelling - the challenges of parenting a robot child that responds in strange and unexpected ways - and medium-term stories where all AIs are cloned from a handful of childhood originals.

Try Ted Chiang's The Lifecycle of Software Objects for the former.

A slight ambiguity

“People effectively go through airlocks,” Diamond said. “The inner door will not open until the outer door is closed. And they make Star-Trek-like noises as they open and close.”

It doesn't say whether it's the doors making the noises or the people supplying the sound effects. Knowing techies, it's about evens which it is.

Re: It won't happen.

NI is not an ID, and if you looked into the reality of the NI system you would understand why. NI is 'good enough' for the job it is intended to do (and that is being kind), but an effective ID it really is not.

I've met people with two NI numbers and people who've found that their NI number was also assigned to at least one other person, thus totally buggering up their pensions. When it works it's fine, but the failure modes are horrid (and usually discovered when you want to retire to a quiet life with bureaucracy).

He has bachelors and masters degrees in Engineering and runs an energy company. It therefore seems conceivable that he could know what he's talking about.

He's also predicting working fusion reactors supplying grid power in 8-15 years. Much though I'd love that to be correct, it rather suggests he has typical techbro delusions about how fast things can be done (and maybe the belief that all safety regulations should be thrown away in order to get there). From many decades of experience I'd say the one certainty of any engineering project is that it always takes longer than you think (even when allowing for it taking longer than you think).
