You've stolen the antiglare shield on that monitor you've fixed – they say the screen is completely unreadable now

iancom

At a previous workplace, we had a number of permanent homeworkers -- they were spread around the country and never came to the office. The process for fixing their computers was simply that we send them a freshly-imaged PC from stock and get them to send back theirs which would be fixed, re-imaged and returned to stock to send to the next person.

One of our homeworkers was a heavy smoker, and clearly did so right at the machine. The first time her PC came back, one of my team dutifully cleaned it out (several times), fixed it up, imaged it and sent it off to the next homeworker in the queue for a machine. They were horrified when they received it and demanded that we get a courier to get it out of their house immediately. When it returned and I inspected it, I could understand why. It absolutely reeked. Not amount of cleaning helped.

After that, we kept those two PCs on strict rotation only for her. Which had the effect that she never received a spec update to the PC, but we're fairly sure she never did much work between fags in any case.

British owners of .eu domains given an extra three months to find a European address

Re: The UK is IN Europe and will continue to be in Europe until plate tectonic decree otherwise.

The poster you quoted wasn't disputing the use of the .EU domain. You are correct that .EU refers to members (or, it appears, close associates such as EEA countries) of the European Union.

What that poster was referring to was that the author of the article implied that the UK was no longer in Europe -- which is very clearly not true. Brits continue to be Europeans, just as the French, Belgians and Italians do.

Apple reportedly planning to revive the MagSafe charging standard with the next lot of MacBook Pros

USB-C Charging is the only thing I like about my MacBook

Haven't used Mac hardware for over a decade and now I have one for my new job.

The only thing I do like about it is that my desk is nice and tidy because there's literally just one USB-C cable coming out of it into my monitor. The monitor powers the laptop through that cable as well as receiving video and acting as a USB hub for the other peripherals.

My Macbook remains permanently plugged into this arrangement. They really might as well have spent less than half that cost on a decent Dell laptop.

Wine pops cork on version 6.0 of the Windows compatibility layer for *nix systems

Re: Much as I like and use Linux

LIcensing, especially when you get into the really hairy world of running in hypervisor clusters.

If all you need is that one service that was written for Windows on one box on your 64-CPU cluster, running it in a Windows VM suddenly means you need to buy 64 Windows Datacenter licences.

Check the cost on that and then tell me it's not worth using Wine!

Dumpster diving to revive a crashing NetWare server? It was acceptable in the '90s

iancom

In the case of the dev box, the failure happens while booting up so before any network stack is loaded. You might assume that a prolonged boot time required a reset, but that could be dangerous particularly on a dev box as it might be checking disks / some other low level operation that could result in corruption if interrupted.

For the original story, NetWare 3.x didn't use TCP/IP, it used some dedicated protocol that I've happily forgotten all about. TCP/IP didn't come along until around 5.x I think.

Go, go, Gadgets Boy! 'Influencer' testing 5G for Vodafone finds it to be slower than 4G

Re: what's the point?

Probably nobody needs 5G right now. I agree it's really difficult to see any need for this when 4G is already routinely getting better speeds than most home broadband connections.

That doesn't mean that there won't be a need for it at some point in the future, though, and if development stopped on wireless data tech, it could end up becoming a bottleneck at some point.

15 years ago when we were all marvelling at our shiny new feature phones with web/music/photo capabilities we realised that our 2G connections just weren't good enough to drive them any more. Fortunately, several years earlier despite there being no immediate need for faster-than-2g data, 3g was being developed and was deployed to suddenly make our feature phones do their amazing stuff.

3g was so fast, there couldn't possibly be a need for 10Mbps on a phone. Certainly not 100Mbps, that would be crazy -- but then came the iPhone, Android, tablets. Fortunately, 4g had been developed despite the need for it seeming inconceivable just a few years earlier.

I've no idea what devices might spring up that make 1Gbps+ necessary. I'm pretty sure they will spring up, nonetheless. It might be driverless transport that needs a huge continuous pipe of data. Weather data collection stations? Perhaps Pronhub will drive an adoption of ultra-super-duper-horrifically-detailed-HD running at 800Mbps? Maybe it's just more about aggregate bandwidth available in an area rather than provision of bandwidth to individual devices?

We don't always envision well how tech will be used in the future. Usually, the use-cases evolve from the capability of the underlying tech, not the other way round.

Car insurers recoil in horror from paying auto autos' speeding fines

Change is needed in the approach to enforcement

The system of fines and points for drivers is intended as an incentive to drive responsibly, a disincentive to dangerous driving and a method to identify and remove from the road those who are likely to ignore safe driving practices and cause accidents.

In this post, I am ignoring the clear fact that most authorities end up abusing this system and operate it as a revenue stream. Clearly, the intention must be that if our enforcement were perfectly successful there would be no fines or points issued because the rules would never be broken.

With driverless vehicles, this becomes very possible. If the system of sensors and software that make up the vehicle are properly designed, it should be possible to make a vehicle that never intentionally breaks any of the rules laid down. The first thing that must be determined in the case of a potential infraction is whether the vehicle was operating in full autonomous mode at the time, and that no software or sensor modifications had been made by the operator.

If there's any deviation from the vendor's system/software or the vehicle was being used manually then the normal points/fine process applies. To whom is problematic, but I won't get into that...

Otherwise, the vendor is effectively the driver. It is their responsibility to ensure that their system and software drives correctly in all circumstances. Per-incident fines and points are not the answer though. Each incident of a driverless car exceeding the speed limit must be identified and the cause fixed, not just arbitrarily fined to anyone (insurance/vendor/owner/operator).

There are several things that must be in place for this to happen.

The rules of the road system must be unambiguous and clear to the automated system. This means a separate GPS-based authority-certified map of speed limits that is available to all vendors at all times. The GPS-map must be authoritative for driverless vehicles such that in the case where the GPS map erroneously holds a 40 limit for a road, but the actual posted limit is 30, there was no infraction by the car/vendor and the responsibility lies with the local authority to go through the necessary steps to correct the GPS map (or correct the posted limits if they were incorrect).

Where the car had access to correct limits and still exceeded them, that must be submitted to the vendor for analysis with a requirement for an explanation and commitment to resolving the fault.

No fine is necessary per-incident, because the intention here is to get all vendors' vehicles to drive correctly, not to punish them for errors.

If, however, a vendor routinely fails to explain of fix incidents of its system breaking traffic laws, then escalating fines will start to be applied to that vendor. Ultimately, a vendor might prove itself incapable of managing its own systems/software and rack up so many fines that it cannot stay in business.

Hopefully, that vendor's existing fleet of vehicles can be taken on and fixed by another vendor, but realistically it probably would leave owners with a vehicle that the cannot use (or can only use in manual mode).

Even in that worst-case scenario, I think I'd still prefer to be left with a vehicle that I cannot drive, rather than left with a licence that's revoked due to the vendor's incompetence -- and no longer able to drive or insure any other vehicle.

Boss put chocolate cake on aircon controller, to stop people using it

Air con wars

Thankfully, for some time I've been in an office where the air con is fixed to about 21/22 C in such a way that only the maintenance company could change it -- no thermostats to be fiddled with.

People just don't understand thermostats. They're really, REALLY simple things. Set it at the temperature you want, and leave it. No dramas. Assuming the heater/cooler is capable of reaching that temperature, it will do so and maintain it there.

But no. I don't know how such a large amount of the population (including my otherwise wonderful nearest-and-dearest) have lived their lives without working out this simple device. Too many people think that setting the thermostat higher or lower will accelerate the rate at which the cooling or heating happens. It doesn't.

Some years ago where I worked in an area with one thermostat containing the IT team (all male) and HR team (all female), the thermostat was routinely swapped between 16 degrees and 25 throughout the day, never just left at 20 or 21 which would probably have suited most people on the floor.

I tried to sellotape the thermostat at 21 several times. Never worked. I never tried chocolate cake. Definitely going to try that at home now.

Share-crazy millennials spaff passwords ALL OVER the workplace

> "... that detected my changing suffix..." meaning somewhere those passwords are kept as plain text

It's perfectly possible that's been implemented in a secure way too -- though my faith in "enterprise software" developers is not such that I'd consider it more likely than the insecure method.

To check for incrementing-number password changes in a secure manner, all the software needs to do at the back-end is strip the last character of the new password (which of course it will already temporarily know in plain-text as it's submitted), then brute-force the original hash with the other nine digits, or even the whole ASCII address space which would probably take less than 100ms for one character, depending on the hash used.

Then, if it passes the test, the software can hash the new password and scrub the plain text.
