Well that much was true certainly.

But the timber lengths were probably all multiples of 0.3m, otherwise known as 'metric feet' by carpenters. It does lead to the problem of some 'full size' boards being 2.4m by 1.2m and others are the full 8' x 4' (2.44m x 1.22m). Very annoying when you really do need those last 4cm, or should that be 1 9/16in?
I am on the TPS list, and still get a lot of green deal, insulation fitting and oven cleaning calls, although the latter seems to have dropped off recently. However, since the caller ID number is spoofed and any company name they give is likely to be false too, how do you know who to complain about to the ICO?
The obvious fraud ones - "I'm calling from BT/Microsoft..." I normally respond to with "[Do you sleep well at night knowing| Does your mother know] you spend your days [committing fraud | as a petty criminal]". They normally hang up.
My son uses one of my old iphones to play games on. It has no SIM card in, so is generally only useable around the house, on the WiFi network. Only I can install new apps on it, and I make sure that everything is suitable for his age. However, adverts do not seem to have any link to the age rating of the app, and I have often seen completely inappropriate ads being shown in the middle of a what is supposed to be an age 4+ rated game. (He is somewhat older, but that is what some of the apps are rated.) Looking at various Apple forums, this seems to be a problem going back years, but Apple never do anything about it.
Take a balloon filled with hydrogen and poke it with a lit match. You will have produced a cloud of water vapour. Now return that to separate hydrogen and oxygen. You all allowed an energy budget equivalent to one match.
Physics proves through the laws of thermodynamics that there is a preferred way for things to go, and that going back costs more energy than going forward. You can reverse things, but only at an energy cost, and eventually you (and the rest of the universe) run out of energy.
This shows an example of how little match there is between many simulations and reality. Having written a number of simulators for various parts of my academic research (a long time ago) I could tweak parameters until there was a good match between the simulator and previous observations under known conditions. However, take one step outside the boundary of those known conditions and I could guarantee the simulator would be useless.
Climate model simulations are the obvious exception to this. They have perfect predictive abilities for up to a century ahead.
Switches in both leads might be the required practice these practice these days. It might even be carried out in new installations. However, it is certainly not always in place in older installations. Light sockets in particular can still be live even when the switch is off.
Exactly. The whole intention of a phishing attack is to make it both believable and tempting. The problem with many unions is that they will automatically consider any change to current conditions 'a bad thing' which needs all details to be communicated, discussed and agreed beforehand.
I am a security consultant and one of the security education services my company is working on will allow test phishing emails to be sent if the client wants that part of the package. As long as there are clues in the email that it came from outside the organisation I would consider it an acceptable test. On that basis, GoDaddy screwed up by sending it from a legitimate internal address and providing no clues at all that it was meant to be fake, but this one I would consider a valid test.
A Chinese wall is not big and impossible to pass. Quite the opposite in fact. It comes from the use of paper screens which everybody then pretends are impossible to go through, and usually refers to artificial divisions to keep information about two areas separated. e.g. A company doing work for two clients who are competitors which each other.
On the basis that it refers to a purely language based construct with no physical presence that stops you from doing something I am surprised it is not praised rather than rejected by reformists of woke or SJW flavours.
Somebody once collided with my car in the company car park, cracking the bumper, but left no note. There were obvious cameras overlooking the area so I went to the security office to ask whether they had footage of the incident.
"We turn the cameras off during office hours."
You could not make this stuff up.
Might have been a flame rather than a spark. Sparks normally have something at the other end to complete the circuit. (As this place is pedant infected, yes, I do know about cloud to cloud lightning). I had a PC back in the early 90s which I had unplugged to plug in something else temporarily. When I turned the PC on nothing happened. Oh yes, the plug. Reach under the desk to plug it back in, putting my head next to the PC case, and a flash of flame goes past my face. There went the main house fuse, the ring circuit breaker, the plug fuse and the PSU fuse. Further inspection of the inside of the PSU revealed a large ceramic (maybe tantalum bead) capacitor with a crater in one side.
There used to be an accreditation scheme - CAS(T) - which telecoms providers had to meet if they wanted to sell into the government or public sector markets. This was deprecated when the new Telecoms Security Requirements were announced. Announced, not available, so this was around the middle of last year. The Telecommunications (Security) Act 2019-2021 has now been approved in late November so this sets the requirements. I would assume that there will eventually be an accreditation scheme, but I am not holding my breath.
As a security consultant who often works in the telecoms area, I can foresee a very dull period ahead reading the Bill and trying to work out what the requirements really are. An initial glance through reveals this will not be enjoyable.
I had a Gateway in the second half of the 90s. Various bits got swapped out occasionally until just the original case survived. Eventually the changing form factors of various components meant it too had to go, but it was still in perfect condition. Built like the proverbial outhouse.
I am sure mine must still be around somewhere, although it was a little smaller. An open case with a 25 way connector on each end and 25 pins sticking up. Jumper leads could be added as necessary. The last resort in my serial toolkit, which also included a long straight-through cable (1-1, 2-2, ... 25-25), short adapters for common requirements such as null-modem or 25-9 serial, gender-benders. If two boxes could talk via a common protocol through a 9 or 25 pin D socket, I could probably connect them.
False positive rates should be low. Really low if you are dealing with a potentially large pool of candidates. A rate of 1% would mean that 1 person in 100 would be falsely recognised as being somebody 'of interest', and in any kind of crowded event there will probably be thousands of facing passing in front of each camera, so 10s of false positives. A 98% rate means this facial recognition system is working at the level of 'yes, that is a face'. It probably even triggers on the police horses.
It might be that 98% of the flagged faces were false alarms which is still stupidly high, but that is not what is properly meant by false positive rate.
When I used to interview graduates for a coding position I liked this test (although back then it was in C rather than C++).
What is the output of the following code:
std::cout << 001;
std::cout << 010;
std::cout << 100;
Most candidates realise the leading zeros will not be printed, and write down 1 10 100 on separate lines. They are wrong. Some candidates realise that the output has no \n and write 110100. They are still wrong.
Gran: up two generations (mother of mother, or mother of father)
Aunt: up another generation then across to a sister
Cousin: shared grandparents, so up two then down two along a different branch of the family tree.
Total: Up five, down two.
So a common ancestor exists five generations up from the starting point, two up from the end point.
Take the lowest number: two, which implies cousin (three would be 2nd cousin, 4 = 3rd cousin, etc)
Take the generation difference: three.
Final result: Cousin three times removed, aka Sherryl.
"Antimatter is just an atom, whose core contains the electrons while the orbits are filled with protons - in "normal" matter it is the other way around."
No it isn't. It really isn't. An anti-matter is made of of anti-protons and anti-neutrons, surrounded by anti-electrons (positrons). It is not just a normal atom flipped inside-out.
A few years ago I had a problem with the house main fuse tripping several times a day. After a couple of electricians failed to find any fault the local electric board sent one of their more competent ones. He asked whether I used surge protectors for any equipment. I did, and he said to remove them. They can cause problems with tripping and are of little practical use: A distant lightning strike will be handled by the mains grid and a too close strike will blow straight through them anyway. Once I removed them the trip faults stopped, and if there is a close storm I just unplug the computers.
As a teenager, so a long time ago, I had a Saturday job in a clothing chain warehouse. Four floors (with perforated metal grid flooring, allowing for good ventilation / fire spreading, and causing vertigo for those working on the upper floors) full of cardboard, plastic and fabric. The safety briefing for new starters stated that in the case of a fire, the fire crew would come in and try to rescue anybody known to be trapped inside, but otherwise would just keep their distance and let it burn.
Flying lego: https://www.popularmechanics.com/flight/a23667/lego-plane-that-can-fly/
Some of the cheap alternatives are so bad that you can put one piece on top of another, pick up the assembly by the top piece, and the bottom piece stays behind. The tolerances that Lego is made to really are very tight, but they have had a lot of practice at making blocks by now and I don't think the price premium is completely justified by that alone.
My son got the Saturn V set (target age 14+) for his 6th birthday recently, which I was banned from 'helping' with. It took him a while, but he was able to build it. He now refuses to consider any sets which are not intended for at least age 8. He has an enormous lego collection, plus occasional access to my old Lego Technic sets, but he still likes building things out of standard 2x4 blocks. The specialised pieces are too specialised these day and no good for anything beyond that one function. Ebay comes in very handy for 'vintage' lego.
