Finally, a wafer-thin server... Only a tiny little thin one. Oh all right. Just the one...

Re: PSU fun

At the start of this century I was a part of a team developing a highly specialised network simulator for a customer. The network that the simulator supported also included RF (SATCOM) components, and the simulator was designed to calculate the intermodulation products that all of the various RF carriers generated. The simulator was actually quite a beast; written in Java with a lot of work put in to optimise it, but with some settings you could more-or-less see the JVM (and the PC it was running on) scream.

The customer originally was planning on installing the simulator on a desktop machine running a mid-range single-core Intel processor. However when they saw the simulator running in the lab they decided to upgrade the target platform to use a dual-processor SMP motherboard with higher-specification Intel processors. This was 100% a customer decision, we did not recommend the upgrade, or (to be honest) gave it any thought at all - our responsibility stopped when we delivered a working simulator.

Eventually the day of the initial delivery dawned, and I went to the customer site, installed the simulator, and ran the delivery checks that verified that everything was OK. Customer sign-off of the delivery was obtained, and everyone was happy at that point.

About a week later we got an e-mail from the customer say that the simulator was causing their desktop machine to blow up! Off I went to the customer site, to be greeted by a very irate representative who proceeded to demonstrate how, when they ran a test scenario on the simulator, the desktop machine it was running on would shut itself down with extreme prejudice after about 20 seconds. I checked the simulator software that we had delivered - no problems. I then asked, casually, whether they had upgrade the desk machine's PSU when they upgraded the processors - I got about 30 seconds of silence before a muttered "Oh shit ..." was heard.

We never had any further problems with the delivered system.

This is only the spacecraft procurement

Keep in mind that this is only the procurement of the spacecraft and TT&C infrastructure; this is not a full-blown PFI job like the one that one G. Brown forced on the MoD for Skynet-5. That went so well that the MoD are not even thinking about going down that route again - ever!

Re: Skynet not Terminator

Skynet did not, but there was a spread-spectrum modem used by the navy that should have provided up to 10 users with a nearly jam-proof 2k4 bps over the same spectrum allocation. I seem to remember that it was developed by BAe. Not surprisingly they managed to screw up the spreading codes so that any more than 2 users sharing the same spreading code resulted in everyone being jammed.

BTW, those modems have long ago been withdrawn from service.

Skynet not Terminator

Lets just be clear here - Skynet is the series of MoD Satcom platforms that dates right back to the early 1970's - way, way before Arnie got into his Terminator suite. Apparently the film makers were looking for a nifty name and thought that they had come up with one that no-one had every thought of, only realising their mistake after the film was released and someone pointed this out to them!

Also Skynet was the first military satcom system; up until it was launched everyone (i.e. the Americans) had been saying that the military had no need for satcom. Skynet-1 was so successful that the critics shut up immediately - the rest, as they say, is history.

Whose side you on, Nominet? Registry floods .co.uk owners with begging emails to renew unwanted .uk domains

Saruman the White

Re: Is this Fraud?

It certainly seems pretty close to it at first glance. Registering a .uk on behalf of a third party without their explicit permission, then sending out letters demanding money to renew the unwanted domains is definitely something that the police might get interested in, particularly if enough people/companies complained. In fact if the amount of money heading into their coffers is enough, it could bring the SFO into play.

'One rule for me, another for them' is all well and good until it sinks the entire company's ability to receive emails

Saruman the White

Seen something like this before

One of our consultants had been working at a major customer's site for several years, and had an e-mail account in the customer's system. Because he was rarely in the office, he set up a similar rule in Exchange to forward all of his internal corporate e-mails to his alternate e-mail address with the customer with a receive acknowledge enabled. Everything worked fine until the contract he was working on was completed (successfully I should add); the customer deleted his e-mail account at COB on the Friday.

Urgent call for me on Sunday afternoon from one of my company's directors - they need to get a significant proposal out to another customer PDQ, but the e-mail system had ground to a halt. A not-so-quick remote log on to the e-mail system later (for some reason, soon to be discovered, the corporate Internet connection was very slow as well) I had a look at the external e-mail server's logs (no, not exchange - the relay server was Postfix, something that I was really glad I had set up) and discovered that it had over 30 thousand e-mails queued for transmission - the two e-mail servers spent the entire weekend playing ping-pong with the messages until things had reach pretty catastrophic levels. More to the point the process was continuing even as I watched.

Emergency action was very quickly taken. The relay server was quickly shutdown (the metaphorical silence was deafening) and its outgoing queue was purged. Incoming messages for the guilty party where temporarily redirected to a bit-bucket (to allow the customer's e-mail server to calm down and purge its queue) and a message was sent to everyone in the company saying that any outgoing e-mails may have been lost and may therefore need to be resent. A more thorough report was sent to the director, who had a little "chat" with the guilty party Monday morning (while I was resetting things back to normal).

Re: Not quite the same...

I can remember doing a summer programming job when I was at university for a certain company (I'll leave their name out of it - you can try to guess). One of the full-time programmers wanted a print out of an application he was working on. However this was on an IBM 370 running CICS - one of the most evil systems around. Anyway said programmer submitted the print job, but managed to miss the print queue and hit a punched card queue instead. He ended up with an 18 inch stack of punch cards on the corner of his desk and a very bemused expression on his face.

Re: Honest question....

Cloudflare goes retro with COBOL delivery service. Older coders: Who's laughing now? Turns out we're still vital

Re: Mindset

When I was a research student (several decades ago) I used to take tutorials on COBOL for under- and post-grads. I loved to start the first tutorial comparing a C "Hello World" to a COBOL one. Made people realise that you actually had to think to be a COBOL programmer.

Oh yes - the reason why I took those tutorials? I was the only other person in the Comp Sci dept (apart from the lecturer in charge of the COBOL course) who had any sort of practical experience in COBOL. Or at least, the only one who admitted to it :-)

I actually believed it for a moment ...

... until I got to the second half of the article.

Funny enough, re-vamping the Saturn-V has been discussed several times. The big problem (and they are BIG) are the main engines; each one had to be basically be hand-made and hand-tuned, and unfortunately all of that highly specialised knowledge is now gone. Shame really since the Saturn-V was really something to see launch, and it never suffered a failure!

Re: wait, what?

GCHQ operates in a purely advisory role in this case; it is the Cabinet Office which is actually responsible for providing secure communications links. As I understand it, GCHQ heard that Zoom was going to be used and basically blew a gasket in response, however the Cabinet Office ignored them and went ahead anyway. the rest, unfortunately, is history.

Re: Signal?

Pretty much the same here.

Implementing these measures is pretty easy in countries that are heavily urbanised, and where good mobile signal coverage is pretty much taken for granted. Achieving the same result in countries with significant rural communities who have poor and/or erratic signal strength is going to be more of a challenge, and attempting to improve the rural coverage (by putting up more base stations) is not going to be a viable option since it will simply take too long to do.

Australian privacy watchdog sues Facebook for *checks notes* up to £266bn

Saruman the White

That could hurt

Up to now FB has been subjected to likely more than a few mild hand raps (financially speaking), now all of a sudden it is facing a public flogging. £266 billion is going to hurt them if it actually gets through the courts; even if the courts disallow 3/4 of the fine, what is left is still going to sting a hell of a lot. If the ICO joins in with its 4% global turnover fines, then FB is going to have to change its ways, or it will go under from the weight of fines.

Starliner snafu could've been worse: Software errors plague Boeing's Calamity Capsule

Saruman the White

Re: Capability Maturity Model ?

Unfortunately CMM turned out to basically be a fad - once the bean counters realised just how expensive it was to implement (a company like Boeing would need to spend hundreds of millions of dollars to get to Level 5) they very quitely dropped it.

This and the 737-Max fiasco has me thinking that Boeing is starting to suffer from a hardening of the corporate arteries. Management have lost sight of what the company actually does (aircraft, spacecraft, ...) and have become far too concerned with the bottom line. As a result of this shortcuts are being made in the engineering (software, mechanical, ...) that are having major Safety of Life implications. The only solution may be a radical overhaul of corporate management, starting at the top and working down to the bottom: the corporate equivalent of "nuke it from orbit, its the only way to be sure".

Ah, night shift in the 1970s. Ciggies, hipflasks, ADVENT... and fault-prone disk drives the size of washing machines

Saruman the White

When those old disk packs fail

I remember one year working for a company who built flight simulators (at the time mostly military, but some civilian). They had a big IBM mainframe that ran all sorts of stuff for the company, both technical applications as well as financial and management stuff. One day the shift operator went into the next room to find the tapes that had to be mounted in preparation for that night's backup; just after he went in the room there has a very loud "bang" followed by lots of noise as of broken glass bouncing off things. When he went back into the main server room he was greated by the sight of the mainframe crashing, and one of the "washing machine" disk drives with a hole in its side, with the metal bent outwards.

It turned out that the lower bearings on the disk spindle had failed, resulting in the spindle tearing free and (along with the disk drives) deciding to take a strolling around the server room. Odds are that had the operator been in the room at the time he would probably have caught some of the debris that was flying around at great velocity.

Took IBM 3 days to haul in a new disk drive unit, wire it up and then rebuild the system from scratch and backups.
