Boss sent overpaid IT know-nothings home – until an ON switch proved elusive

Re: Way Back...

" Makes it obvious that it's NOT a regular power outlet."

That's the rub. If there was a regulation colour for these sockets, or even if someone had the foresight to _label_ them a lot of angst would be saved.

On a slightly larger scale version of this, about 25 years ago I solved a similar problem which had been flummoxing our staff for years. A site was reporting critical equipment (radio-operated phone system long before the days of mobiles) failing over the weekend and when we got out on site it was always working perfectly. As it was a safety requirement needed to talk between the customer's base and ships anchored about a mile offshore taking their bulk product (titanium ore) it was causing major problems and the faults were becoming more frequent.

The site was about 100 miles from base, so callouts were difficult and the customer wasn't willing to pay callout charges in any case for what they felt was our problem.

One friday evening, I'd finished late at a remote site about 200 miles from base and was heading home when a call came in that this site had just reported a fault and as i was about to pass it, would I call in and see what's up?

Late on a summer's night (10pm sunset) is spooky on an ironsands mining barge when everything's shut down, but once on board I made my way to our equipment cabinet to find what was apparently a power supply failure. 5 minutes of prodding and poking later established that the dedicated socket installed and labelled for the equipment ("Do not turn off at any time") was dead and further prodding/tracing revealed that the socket was wired back to the "Non-essential" power cabinet - and had been since our equipment was installed 20 years earlier.

Guess what happened at 5:30pm every night? The hint's in the name "Non-essential power"

Thankfully there was a live socket about 2 metres away, so phone service to the ship visible on the horizon was quickly reestablished. The following week someone went out and replaced the lead-acid battery in our cabinet which proved to be thoroughly trashed. 20 years of being discharged overnight every night and deep discharged every weekend/public holiday had taken its toll and it was lasting about 15-20 minutes at best. I don't know if the dedicated socket was ever rewired to the correct power cabinet or whether the short extension cable to the essential outlet was left in place.

Checking the installation documentation it was clear that the customer had signed off on the requirement that our kit was on an "essential" power feed and that over the years they'd verified it wasn't connected to the non-essential power when we asked them to double check. (The plug was labelled as "essential power, do not switch off", but the circuit label on the socket was in site convention for their non-essential stuff(*) and we verified it actually went back to the breaker it said it did)

(*) Site caretaker electrician "That's a non-essential circuit designation, they get switched off at 5:30" - to which my response was "It's supposed to be on essential power, we're going to have to verify this"

The customer got a report. They still complained about the length of time that it'd taken to diagnose the fault, despite the fact that due to the nature of the power "failure" (and the responses of their supposedly qualified day electricians) the problem could only have ever been diagnosed onsite at the time it was happening. I was the first out-of-hours visitor _ever_ and they'd been the ones to refuse out of hours callouts due to the charges they'd incur. The only reason I was there was because they called it in whilst someone was still in the office _and_ someone was in the area who knew the site (it was regarded as dangerous due to the bailey bridge used to access the barge, so going there needed a familiarisation trip) and it had such a long and frustrating history of "no fault found".

Not just on PeeCees and still a thing today.

Supposedly technically competent users (even actual technicians) put them in so they're (barely) working and don't give them a good hard shove to get that last 3-5mm home. Result being an intermittent connection.

> I was initially inclined to side with NT2 on this on principle, but using Carter-Fuck? Defenders of Scientology?

According to the initial report here, NT2's trial was not only heavily covered in media, but he was stupid enough to give interviews about the conviction after being released from prison.

He got his way in court because the judge decided "he was truly penitent" (unlike NT1, who lost) - which is something neither you or I would have gotten if we'd been giving interviews before the conviction was spent. There really is one law for the filthy rich and one for everyone else.

"The American Space program was crap in the early years too. It also suffered big setbacks."

And they learned from them. One of the lessons being "don't trust contractors"

From the Earth to the Moon miniseries was pretty good at covering much of this.

One good example being the Apollo1 fire. Whilst the proximate cause of the disaster was too much velcro in a pressurised oxygen atmosphere (polyester is explosively flammable in that environment), when a capsule was torn down to see what started the fire it was found to be so shoddily built that the sparking wiring that triggered the fire was the least dangerous of the many faults which could have killed astronauts in orbit.

Quality control is important.

Re: Serious question.

"1- satellites orbit in the same direction"

Initially yes, but it doesn't take long for them to start crossing paths at anything from "nearly parallel" to "head on" paths.

1a: No.

2: Impact speed is dependent on approach angle and varies from 2 * orbital velocity (head on collision) to almost zero (matching orbits)

It's not just collisions either. Several second stages launched in the early days spontaneously exploded after some several years in orbit, leading to changes in mission policies that all valves were opened and every thing vented at the end of the operation and since concerns about obiting junk were raised in the 80s to more modern policies that stuff is deorbited quickly (Skylab's booster took several months to come down and wasn't controlled. NASA and the USAF took a close interest in where/when it came down as they felt it was a good proxy for how Skylab would eventually deorbit.)

Bear in mind that only the "big stuff" is being tracked and counted. Depending on whose figures you believe, nothing smaller than 5cm or 10cm is trackable. It only took a fleck of paint to gouge a chunk out of a space shuttle window.

Most people aren't. The science part is easy, it's the engineering that's hard.

That said, in any government or governmental organisation some level of reform is always needed and the UK is arguably worse than the EU in this respect. A report has just surfaced that HMRC refused to act on EU warrants to investigate money laundering due to the political donations and affliliations of the companies involved - then denied that they'd given this as the reason, then denied the denial.

You couldn't make it up.

"Guardian and Mail are at identical levels of gutter-rag status"

I take it you haven't noticed the Telegraph's taken to issuing foam-flecked rants over the last couple of years, apparently on the basis of "if you can't beat the red tops, join them"

By comparison the Guardian is an editorially well-balanced rag, but that's not really saying much when virtually all the UK papers display obvious and heavily biased editorial policies. We all know that the Mail openly endorsed Moseley, brownshirts and that nice Mr Hitler chap. Its policies have never really changed since then, but a lot more papers have been joining it recently.

Re: Before we get too excited. Keep in mind Canada is a member of ESA.

It also pays in a lot more than the UK does.

ESA is a consortium which gives out work based on how much money gets put in by the consituent members. Of Europe's spacefaring members the UK has the lowest contributions for a long time and has also been demanding far more than it contributes for a long time.

In many ways Brexit is an excuse to get rid of an annoying leeching partner, or at least making it pony-up what what it should be doing. The UK has built up a huge amount of resentment across Europe with its endless demands for special treatment and as such it's no surprise there's little appetite amongst european leaders to continue extending those privileges when Britain is seen to be whipping up xenophobia.

Even if Brexit was cancelled tomorrow, the special deals would likely go away and the UK told to contribute according to its actual worth as a partner. The alternative (going it alone) has been tried before - it's rather ironic that it's the old fogeys and kippers all voted for brexit when they should be the ones remembering how bad things were before joining the EEC/EU pulled Britain out of the shitter.

I can think of one.

Rental of IPv6 is much cheaper.

And if you complain, all the cheerleaders will come out of the woodwork and tell you that's how it's supposed to work.

And if you point out that the RFC says that all octets are always decimal, and the software is supposed to be RFC compliant, so either the software or the RFC needs changing, they'll mailbomb you.

Alan Brown Silver badge

Re: Compatibility

"cretins who designed IP6 had given some thought to making it backward compatible"

They did. It's flat out impossible. IPv6 is 128 bit address space. IPv4 is 32-bit address space. You can address IPv4 from IPv6 but not the other way around.

In 1995 there was a meeting held with the objective of getting IPv6 deployed before the next "killer app" drove up Internet usage and made changeover harder. That same year in another room in the same conference centre at the same conference _at the same time_ there was a BoF meeting on html standards and the world wide web. Damn that Berners-Lee fellow!

The ironic thing is that IPv4 was originally going to be 128bit addressing, but Vint Cerf was browbeaten into reducing it to 32 bits because V4 was a kludge expected to only be needed for 5 years at most until the "real" internet protocol was developed.

Re: @boxplayer - "Nobody uses it..."

"How did we ever manage to migrate from IPX to TCP?"

"We" didn't.

TCP/IP IPv4 was the hacky kludge we implemented whilst the Internet protocols were being developed. That turned out to be IPX and was unroutable. (IPX = "Internet Protocol Exchange" aka IPv5)

Anyone using IPX was in an island of their own or a couple of isolated offices until they accepted the inevitable and switched to TCP/IP.
