Nope, code was clean with -Wall on arm-9 compiler (i.e. gcc). Interesting thought now you say that (no warning) - only found it because of seeing the pattern (apropos the article) and from that having a good idea what was causing it (knowin

Nowaways you just write 'divout = divin/8192' and assume the compiler is going to do the right thing (and very possibly do something deeper than "divin>>12" at the assembler level). Makes me wonder who pays at

Funnily enough just spent a day tracking down a weird problem in an embedded system - some event timestamps were getting corrupted in a weird way. The pattern wasn't obvious until in desperation I dumped them in hex and found the secon

There has long been a live page from lancs.ac.uk [0] - it's currently showing the very high values from last night. Slightly strangely - and a slight chance of being related - we've had multiple power cuts here (Sussex) throughout

I recall having to sort out spaghetti Fortran back in the '80s; numbers as labels (a la basic but with free-form numbering), computed gotos back and forth in the code, stuff like that. Learnt a lot from fixing that mess. Forty years la

Publish it widely enough and someone will recognise the terrain (especially with things like reservoirs visible). To automate it, trace the outline of bodies of water and compare to public data, e.g. SRTM [0]? Lots more detail (and a good j

Ever tried setting 'init=/bin/sh' on the command line? That gets you a shell (or any other program you care to run) and from there a little creativity is all it takes.

My kids hearing about Bing are confusing him with the BBC character (and his carer 'Flop'). The cartoon character is painfully naive, but somehow his carer always makes it come good (and Bing never seems to learn too). [0] https:

I understand. Still, the point remains that the AI is, in this case, clearly inferior to humans (I would have been impressed if the humans found 20,515 signatures and the AI only - verifably - found eight of them to be worth following up).

How to not install recommended packages? (there wasn't a choice, and anyway not installing recommended packages often implies - rightly or wrongly - security risks).

Thanks, hopefully this'll turn up on a google search for someone who just wants to turn simple text markup into a PDF ('apt' didn't offer the option of not installing asciidoc-dblatex).

You probably have X and Wayland installed (quite why those are required for asciidoc is a question I'll leave for others).

Main killer for me - admittedly because I like sharp tools, and it used to claim to be 'lightweight': 'apt install asciidoc' (and I had to delete most of it, because - for the first time ever - I got an HN message about

If we assume that Backblaze gets special treatment from every manufactured who supplies it, that would suggest we're seeing stats that are the best the manufacturer can manage. Which seems a reasonable proxy for what they sell (lots of

Depends on the qualities of the gyros. My step-dad flew 707's between NY and London, and INS on those used the same kind of system (obviously more pro version) - one of the reasons it was no longer necessary to carry a navigator in th

It's still pretty easy to replace systemd in Debian with sysvinit (we do it at moderate scale). Devuan works very well though, basically there's little difference between Devuan and Debian without systemd (all the packages are ide

Bugs and complexity is the usual reason. It seems to be a competence thing - experienced admins find it harder to debug and fix systemd issues, while regular users care less about being able to pop the hood and fix things themself.
