Third rail systems are DC and have traction return currents appearing everywhere that they shouldn't. They must have alarming effects on magnetic compasses nearby

Wrong, your plumber who comes to fix your tap is not your employee because he does not work for you most of the time and is free to do other work
The ride hailing and food delivery companies forbid working for a rival, provide uniforms and logos. That is a contracted employee.
It was the norm. Overlooking the change in DC supply and the affected components is a remarkably obvious error. Experienced engineers know that breaking DC power is a minefield.
I heard that the shuttle booster O rings was a consequence of US pork barrel contracts forcing the boosters to be built in sections for transport. Building in sections has to be significantly heavier than a simple tube
Filezilla is my go-to opensource FTP client
Actively maintained and still generating a stream of bug fixes to cope with all of those "not quite right" servers
I can see why pulling an afterthought FTP function from a browser is a good idea.
It supports FTPS and SFTP as well
The effect of these applications has been to make all legal routes equally jammed. My journey always gives the fasted route as the wrong way down a section of one way street because that is what the motorcyclists do and how Google "learns" restricted junctions. They don't bother to actually check road signs from the road
I will wait for the dust to settle on frequency assignments before I buy a 5G set.
In Malaysia 5G will be 700 MHz, 3.5 GHz, 26 GHz and 28 GHz
The 2x GHz will be of little use as the range will be pathetic - physics
That is a challenging range of frequencies to tune, without even adding existing bands
The ~5.6GHz section of the 5 GHz block was excluded from the ISM band in most countries because it was used for weather radar first. It has gradually been released to WiFi use as the radars move out.
Unfortunately WiFi scanners detect 5.6GHz as unused spectrum free from interference and go for it without reading the rules
My I5 is a 2320, pretty ancient.
Intel Hyper threading seems to far more affected by the bugs than AMDs method and Intel seem to have lost speed advantage.
I am guessing that Ryzen 3 will be fairly expensive and likely peak in price at the year end as Win7 dies.
I always prefer desktops, the second memory lane makes a huge difference. Laptops only seem to ever have one ram module fitted.
I am replacing a aging Windows 7 desktop this year before EOL and was planning to get a Ryzen 2700x, but thanks to too early release of info about the 7nm process I am in a dilema. Wait for Ryzen, get a 2700x when the price drops. Neither means buy now.
I currently have a I5 and it has become glacial in the last year thanks to all the patches against the various Intel cache security bugs, no way I want another Intel CPU
The Malaysian tax assessment system has to be about the most efficient and well run service provided by the government. We have a parallel religious taxation system to make life much more complicated and I still got this years refund in a few days straight into my bank account.
So even developing countries can do this efficiently for free.
Unfortunately they don't teach the need for a wetting current at university these days. Most cars use some sort of micro switch with plunger for this sort of application
A quick sample from Omron shows something like 1mA at 5V as a minimum ie 4k7, a surprisingly low value for the average fresh engineer.
