Oxford chaps solve problem in 1982 Sinclair Spectrum manual

Yeah, what the F! BEEP!

I mean, using a Pi for something the Speccy could do itself...

And frankly, why did they need so many Speccys?

Citroën C4 Cactus BlueHDi: A funky urban crossover

Re: Cactus?

I really wish whoever downvoted me would post his issues with my post...

Also, all the problems I mentioned I have seen in real-life, just so that is clear.

Re: Cactus?

Citroën got a lot of bad rep in the 70s, not because of bad build quality, but because of bad mechanics!

"Dunno what's so special 'bout this LHM oil. Just use regular engine oil!"

(It's OK for an emergency, but will quickly destroy the seals in the hydraulics, and will require a complete and expensivee flush as soon as possible.)

That's not counting those who topped it up with anti-freeze(on the GS that was doubly moronic as it was air-cooled), servo-steering fluid or just plainly ignored for a decade or so...

Then there were the newfangled alloys used in the cylinder walls and tops...

How many 'mechanics' destroyed the heads on the flat-four on a GS when they 'tightened up the exhaust manifolds so that it held' instead of to the specified torque settings?

One mechanic actually 'tested' the suspension of my GS by pushing down on the rear, then stating that my shocks needed to be replaced...

I started the engine and told him to try again...

How many garages had the equipment to properly test the 'shocks' anyway?

One, who claimed to be a Citrën expert (not authorized, though) wasn't aware that the airfilter in the GS was of a 'wet' variety, and usually only needed to be washed in petrol.

And I have similar tales for the CX and BX, too...

On my Berlingo I do everything myself!

Win 95 code gaffe nearly made Stuxnet Suxnet, say infosec blokes

Trygve Henriksen

Re: Luck, or Unicode? Neither - just accurate coding to the API.

Yes, but...

On which platform does the code run?

On the already-infected machine, scanning for other victims, or on the target during the infection process?

Just curious.

(Haven't programmed directly on a Winblows platform since 3.0. )

The Colour of Magic is a good book, and a great spoof of Fritz Leiber's work, but sadly, less of a Discworld book than Strata. (In my not so humble opinion)

BOFH: The ONE-NINE uptime solution

Trygve Henriksen

Re: One Nine would be 90%, surely.

90% uptime is a 'one niner'... Yeah, right...

For practical use, neither 9% nor 90% is tolerable, so the scale really should start at 'Two niner'(99%)

(90% uptime means the system can be offline for over a MONTH each year... 9% means about one month uptime/year. )

Two niner is about what I'd expect for personal websites and low-traffic, special-interest forums on the net.

Re: One Nine would be 90%, surely.

The 'nines' is a reference to how many '9' are in the uptime statistics.

One nine = 9%

Two Nine = 99%

Three nine = 99.9%

Does 'three nine' sound good enough?

Actually, it's slightly over 8Hours, 45Minutes downtime/Year for a 24/7 system.

A 'four niner' means slightly less than 53minutes downtime/year.

BYOD is NOT the Next Biggest Thing™: Bring me Ye Olde Lappetoppe

Trygve Henriksen

Re: Uh?

Over the head?

You make certain to go to the Big BOSS first!

All company-wide IT policy should be approved by him personally.

If he says 'No' to BYOB, you can tell any wannabe asshat to go take a hike.

If he says 'Yes' you ask him for permission to take 'reasonable precautions'(and make certain that he agrees with those precautions).

In fact, there should not be a level of administration between the Big BOSS and the IT department. He is the only one who should be able to tell you yes or no to anything.

Re: Secure erase....

My office-supplied phone is a JesusPhone 5(16GB)...

So I see no reason at all to even try accessing my work mail on my Samsung Pocket whatever.

Anyway.

A corporate network is bound to have security holes, but it's up to us as users and administrators to make certain that those holes are as few and far between as possible.

If someone wants to read corporate email on the phone/tablet/watch/internet-connected toaster... then it's up to us to make certain that outsiders who 'happen upon' that device doesn't get to that email...

Or the network it resides on...

That's why the 'remote erase' requirement. If someone nicks the iThingie, we want to be able to delete ANYTHING job-related. Unfortunately, it also means that private stuff goes to H!, but I can live with that...

Secure erase....

We have a Wifi network dedicated to BYOD stuff like notallthatsmartphones and tablets, and 'everyone' wants to read their email on their devices...

Quite a few reconsider, though, when they have to set up security measures on the device(password protected screen saver) and agree, in writing, to us being able to remotely erase everything on it.

$10,000 Ethernet cable promises BONKERS MP3 audio experience

Trygve Henriksen

Re: HiFi Power cords

Eh...

Power supplies in audio equipment are Switch mode, and generally operate at 20KHz or higher.

Generally, they operate by rectifying the AC, then using a 20KHz oscillator and a PowerFET(fancy transistor) to chop the rectified power up into 20KHz square wave, pushing that through a transformer, and rectifying the(lower voltage) output of the transformer.

Line noise doesn't get through that...

And the 20KHz that might get introduced into the system is inaudible anyways.

(Which is kind of the reason they use those frequencies)

And any audio equipment that doesn't have a Switch-Mode PSU wasn't worth the $4.99 you paid for it on dx or aliexpress...

ALIEN EARTH: Red sun's habitable world spotted 470 light years away

Trygve Henriksen

Re: I am hopeful

There's some speculation as to how long a civilisation actually outputs identifiable radio signals.

Our early signals are all pretty easy to decode(plain AM or FM, or even Morse)

Add the TV signals and it gets a bit moe dificult. Not impossible, just takes a bit of trial and error as soon as they see a pattern.

Now, imagine today's digital radio, or the signal being sent to a satellite for broadcast.

Our strongest transmitters today are probably those used to talk to assorted probes in space, and they're highly directional.

How long will we even continue using Radio waves?

Maybe there's only a short (less than a 1000 year) window when civilisations use radio?

Robox: How good could a sub-£1k 3D printer be?

Trygve Henriksen

The iBox Nano not only has a small build area, but the resolution isn't all that good, either.

(I still backed it... We'll see if it arrives in April or is hit by the usually Kickstarter Delay)

Talking about cheap...

The Peachy Printer (sub $100) resin printer is now nearly a year late...

Another interestng printer is the Overlord 'kossel style' 3D printer.

This one even has a backup battery built-in.

Fake antivirus scams: It's a $120m business – and alleged ringleaders have just been frozen

I got him confused by first saying I didn't have a 'Windows key' on my keyboard, that it was a very old keyboard, then that I didn't have Internet explorer or Firefox... But that I did have another browser I could start...

BOFH: SOOO... You want to sell us some antivirus software?

Trygve Henriksen

Re: Meh....

Didn't Peter Norton sell off everything long before there was a 'Norton Antivirus'?

And I seem to remember that when Symantec introduced NAV 1.0 they set up stand at a computer show and advertised that people could come and have their diskettes scanned for free...

And that reporters from PC Plus took them up on it, and brought diskettes that really should be tored in lead-lined containers...

NAV didn't find a single virus, and when pressed, the booth-drones admitted that they were using a non-working 'pre-release' version.

I wonder how many visitors went home with virus-infected diskettes that day...

Unfortunately, we're using the current version at the office, and it can't even protect against browser hijackers...

Re: Even newer vehicles can benefit

89 Octane?

No wonder fuel is cheaper over there... you get the dregs...

Here in Norway, 95 octane is 'normal' and 98 is 'high octane'.

They also sell 92 octane in and around Oslo. It's probably OK if all you do is sit trapped in rush-hour traffic.

Re: Hypermiling

Can't blame you...

I once overtook a 911(9something anyway) with my 1999 berlingo(replaced the 1998 mentioned in another post after a cunt with a SUV but no clue wreced it in a parking lot)...

Boy does the 1.4i scream when you throw it from 5th(it was doing 60Km/h) down to 2 and flooring it.

Woke up the b@stard in the Penisextender, at least, since he overtook me on the next straight part of road(read: 5Km later. This is Norway after all)

It was worth it to take that hit on the mpg...

Re: Home mechanics...

I had my 1998 Berlingo (1.4i) in for an engine replacement...

(My fault, sloppy maintenance)

The replacement was from a 1997...

The garage first tried to use the ECU from the 1998, then when they realised it wouldn't work with the injectors on the 1997, they tried to swap over the injectors. (No good. Different physical size)

All because they didn't want to swap out the ECU...

(The Berlingo didn't connect the ECU and BSI until 2000, when they did a big overhaul of the electronics. So no reprogramming anywhere to do this job)

On an earlier car of mine, the instrument panel had no lights after they swapped the speedo cable.

I think I prefer to do the work myself from now...

Re: Lister and mirlees diesels...

I remember an anecdote a friend told me.

A buddy of his had bought a 1970s fishing boat, and was rebuilding it to live in.

The SABB (No, not the Sweedish SAAB) diesel looked as it had never been serviced, so he searched around and found plans and parts lists, then called the factory and tried to order a full service kit,(gaskets, bearings, injector, the works).

The factory spokesman refused to sell him more than a few gaskets, because "There's no way that engine needs a rebuild yet!"

(If you build an engine to be used as the sole propulsion on a boat destined for the North Atlantic, you tend to err on the side of solidity)

No TKO for LTO: Tape format spawns another 2 generations, sports 120TB bigness

Re: Lowest-cost archive medium

Please, NO!

DO NOT mention DAT and backups together!

The only media worse than DAT is VHS tapes. Even 8mm tapes were better!

DAT tapes can't F! handle the all the sudden starts, stops and winding operations and will stretch the band, making it unreliable after just a few uses.

I've used them all, DAT, Mini DV, 8mm, QIC, SLR, DLT, super DLT, LTO2, LTO3, LTO4...

And probably a few I've managed to repress the memory of...

For home use today, I'd say to use multiple USB or networked HDDs, do 'full backups' and not to trust a drive older than 3 years.

I have a 'main' 4TB networked drive at home(locked in a closet together with the router), and two USB drives of the same capacity. Every month I backup the networked drive to one of the USB drives, and bring it 'offsite(drawer in my office), then I bring home the other drive to await the next 'full backup'

Any changes between the backups is copied to a USB-stick.

In the case of many changes or lots of files added(ripping a complete Dr. Who season from DVD, maybe) I do the backup as soon as the changes are done instead of waiting for the 'monthly'

Bring back error correction, say Danish 'net boffins

Re: Trevor for the win!

Sure it's security.

A NATing firewall won't resend anything that it doesn't have a translation entry to.

And only machines on the inside of the NAting firewall can set up those tables(done automatically when it accesses something on the outside. )

Which means sending a 'reply' package won't get through to a machine on the inside unless it has actually sent an initial package outward first.

It's a pretty effective filtering mechanism, really.

(Unless the attacker can sniff outgoing packets, of course)

Yeah, I can't understand why they threw out NAT, either.

Maybe they thought the only reason people used it was to allow more computers to use the same IP?

But the most important reason is to hide your computers.

I want as many layers of security between my computers and the big, bad internet as is possible.

Don't touch that CABLE!

Last year, I think it was, I had a call from one of our offices. They had moved the big multifunction machine(print/copy/scan/fax) around a bit, and had managed to rip out the fax cable...

They had found a similar cable but that didn't work...

(I knew that the office had had 3 major rebuilds of the wiring in the years since it was built, and also that the first fax in that location had been a bit 'special', so the odds were that the cable had been a custom job)

I told them to NOT touch the cables, then jumped into the car and set off for a 1.5Hour trip.

Guess what I found when I arrived?

Not a single cable!

The one they had borrowed, they had of course returned, and the broken one they had tossed out somewhere.

So instead of spending 5 minutes making a copy of the old one, or just crimping on a new connector, I spent an hour digging through 2 decades of dust and grime following the cabling to the end, and replacing every custom job with standard cables.

The same with printers.

If someone calls me to tell me there's a paper jam, and that the 'paper ripped' when they tried to fix it themselves, I always tell them not to throw away the pieces. Which they do anyway...

(Luckily, they usually throw them in the closest recycling box, though, so I can find them)

Why I want the pieces?

So that I can tell if there's still paper trapped in the machine or not.

(I'd rather spend a minute with a paper jigsaw than 15 minutes with my hands inside a contraption of sharp edges, fiddly screws and god knows what, making certain the bl**dy thing won't crash again 5 minutes after I leave)
