It's not so bad when it's one of your own, but working on the Cambridge Science Park in the early 80's, we had lots of VIP guests (and I mean very). Margaret Thatcher and Prince Philip to name but two.

Only true boffins will be able to grasp Blighty's new legal definitions of the humble metre and kilogram

Alan J. Wylie

The 1959 International yard and pound agreement

This new definition won't have any practical effect, however, back in 1959 there was a change which caused the UK inch to increase in length by 1 part in 2 million.

Remember also, that the US (some states, not all) uses two different definitions of the foot, which differ by about 1/8 inch per mile, which can make a significant difference.

An Internet of Trouble lies ahead as root certificates begin to expire en masse, warns security researcher

Alan J. Wylie

Re: Simple solution

> it's the expiry date of the Certificate Authority's root cert

Except that no CA these days will issue a cert valid for more than 2 years. His must be self-signed.

Re: Scott Helme on expiring TLS root certificates

It's not the renewing of server certificates that's the problem, nor even intermediate certs. It's the trusted root certificates that are embedded into operating systems and browsers. If those aren't updated on the client then the breakage happens.

Alan J. Wylie

Scott Helme on expiring TLS root certificates

A timely article:

https://scotthelme.co.uk/impending-doom-root-ca-expiring-legacy-clients/

HTTPS is a bit more than 25 years old. A lot of early root certificates were issued with a 25 year lifespan, and are about to, or have already (Addtrust) expired. Without updates, the web will break.

Re: DEC Fortran

Back in the early 80's, I used DEC FORTRAN on a VAX-11/780 developing an early Geographic Information System (as it is called these days). I remember one program (interpolating spot heights on a grid from contour lines, perhaps) which did a lot of looping over arrays. There was a DEC supplied program that drew a text based representation on a VT100 of pages being swapped (paged?) in and out of memory (we originally had a huge 512kB, later expanded to 3/4 of a MB). You could see when you had your array indices the wrong way round, pages were rapidly swapped in and out all over the place, rather than a neat little chunk with pages being added at the end and lost at the beginning.

That computer (about 1MIPS) and memory were enough to run an interactive line following digitising program as well as several developers simultaneously editing and compiling.

ALGOL 60 at 60: The greatest computer language you've never used and grandaddy of the programming family tree

Alan J. Wylie

Re: I've used Algol-60 at school

Me too.

Probably 1973/4. We wrote out programs out on coding forms, making sure that our 0/O and 1/I were distinguished (I can't remember any more which one had a slash through it). It was sent off to, IIRC, Lancaster Uni, where it was typed onto punched cards and put through the batch system. A week or two later, we got the output. It took a long time to get anything that would compile. I think mine did run eventually, busily calculating digits of pi until it hit its CPU limit.

Shipping is so insecure we could have driven off in an oil rig, says Pen Test Partners

At a previous place of work, one of the consultants went to check the security of some of a cruise liner's systems, mostly for on-board purchases and charges. PCI DSS sort of thing. It only took a day or so, but they weren't going to change the ship's schedule, so he got a few free extra days lounging around before it next docked. Nice work, if you can get it.

A couple of memories: Laser-Scan was frequently visited by VIPs (Prince Philip, Margaret Thatcher to name but two). The server room was cramped, but the dignitaries were always shown around: "VAX 11-780 with half a megabyte of RAM!". Running in shouting "which *** pushed the read-only switch on the drive" after someone had butt-pressed it could be a career limiting move.

Also, if you found a pack on the floor, you didn't just assume it was untidiness: it might have been left on top of the "washing machine" and the vibration could have shaken it off, disturbing the alignment of the platters. Mounting it (in the days when that was a physical action) would almost certainly lead to the destruction of the heads.

Parys Mountain Mines?

One of the minor creditors is Parys Mountain Mines Ltd., owned by Anglesey Mining plc, a company with an "interesting" history.

What made the name stand out for me, as a caver with an interest in mines, was the fact that the deep shaft they have was mentioned in connection with storing power by raising and lowering a large weight, a method being developed by Gravitricity.
