Indeed, for many years we've been running multiple systems with X86_64 kernels and a 32-bit userspace, running many standard 32-bit applications (including browsers); only thing we've ever needed to do is run 'linux32' b

Once you know the pattern, it's super-easy to 'assemble' PDP-11 programs in your head. For example, for a double-operand instruction like 'MOV', the lower 12 bits are 4 groups of 3 bits specifying addressing modes a

We used to fit all the diodes then use a pair of contacts connected to a high current supply to blow the unwanted ones. The diodes make (and still do) a nice little flash as the internal point contact blows. IIRC you could tell which ones w

My first boss was a demon at loading the bootstrap, fingers sweeping back and forth across the panel to bring the system up every morning. Later I got to write a boot ROM which supported 5 different drive types (4 types of floppy from 3.5&q

A while ago now, the Oklo nuclear reactor ran - according to wikipedia [0] - for a few hundred thousand years albeit only with power levels averaging less than 100 kilowatts. It was discovered because there was a discrepancy in the amount o

Debatable if this should be flagged? (politics) I'm personally pro-science but this does seem to be intended to sway voters.

Always worked for me on Thinkpads (T41/T61/T420/T520). T420 reports a somewhat optimistic "122 hours remaining" when coming out of sleep with a fully charged battery though.

'Ville' translates as "town" so "Green Town" :) Similiarly in the UK 'Downs' is an old english word for hill so I'm always amused by a local 'Highdown Hill' ("HighHill Hill")

Ashford Kent and Ashford Middlesex are common issues in the southeast. As for Hawkridge in Devon...dark night (not stormy) and it was only when I saw Dulverton road signs I got the sense this wasn't going to plan.

If enough people add the tag to their 'about' page, that could help keep it going.

Question here is about the "reasoning" tag - behind the scenes, is this qualitively different fron stringing words together on a statistical basis? (aside from backroom tweaking and some randomisation).

In the old drives of 5" HDDs the head stepper motor shaft was external, and if a drive got stuck a slight twist of the stepper shaft would unstick the heads after which the drive would spin up (well, as long as it didn't rip heads

My first hard drive was 5Mb, and I had to write my own driver for it (PDP11, c. 1982). It was a hell of a step up from 8" floppies, enough so I partitioned it into 8 separate areas. Even the floppies were a step up from paper tape - th

What's actually needed by investors is knowing whether this is correct in economic terms, i.e. whether it predicts who will ultimately be IPO'd successfully (make money for VC's and friends then bombs) or whether the company

I expected far more comments about how the profit motive so often manages to drown out the scientific evidence; little disappointed how far down the page I was before I saw yours.
