I tried apple. I really wanted to love it. I hated it.

If you spent loads of money keeping hardware and software bang up to date you could get about 1/4 the performance of anything running Linux or windows.

This will be the death knell of Apple as a power workstation machine. Unless they keep intel for that.

This'll make you feel old: Uni compsci favourite Pascal hits the big five-oh this year

itzman

pascal was simply useless.

..for any real software engineering.

I rewrote yards of it into C so that I could actually get code to work. It was so strongly typed that things like reading two bytes of a comms stream that might be a bit field, two bytes of data or a particular error code was almost impossible without creating a union of every possible thing it might be.

And if you were stuck at the coal face nested 15 levels of subroutine deep and you encountered the sort of 'line's dropped on you mate' error the inability to 'go directly to jail without passing GO' with a lon gjmp() produced a nightmare of messy code .

Academics loved it. Engineers avoided it.

Of course the fashion is now to type overloading, leading to an equal mess.

Academics should be banned from writing languages

Facebook to surround all of Africa in optical fibre and tinfoil

Re: Choice of countries

I'm somewhat surprised by the choice of countries. For instance, why is a country like Namibia (with its fairly large mining, manufacturing and banking sector one of the rising stars of the continent) not included whereas a non-African country like Oman is?

Namibia has good fibre links to South Africa, and not a lot of population. Its also a hard country to get power to and from

Oman is full of rich people needing to play online video games.

Backup is a copy . Where it is and how connected it is are very variable things.

I do auto backup. If my data were corrupted the backup would be, if I didn't notice for 24 hours.

But I am protecting against hardware failure, not malware.

If I were concerned about that, I would do a check on file/backup and if the difference were massive abort and notify.

I don't consider that this particular malware is a serious threat on Linux.

staggeringly similar story.

did a bit of coding for a client who sold a business app on either Elonex or Apricot PCS. yep DOS days of course.

"Does anyone buy the Apricot" I said'

"Yep its ten times faster"

He proceeded to demonstrate with much whirring of floppy disks.

I was puzzled, Processors and speeds wer identical.. then I had a thought. Sho nuff the elonex had in config.sys :

FILES=2

BUFFERS=5

on the apricot they were much higher.

I edited the file rebooted and said 'now try it'

Boeing big cheese repeats pledge of 737 Max software updates following fatal crashes

itzman

Re: Want to try to reprogram it so it feels and drives like an F1?

If the angle of attack was zero on the runway the aircraft would not be able to take off.

Wrong.

1. Airfoils are capable of generating lift at zero angle of attack.

2. That's what the elevators are for - to push the tail down and the nose up.

Re: Seafire conversion of Spitfires in the 1940s

First of all spirfires were always tail heavy and always flew with down trim. In fact being on the edge of pitch stability makes for a very very sensitive set of controls. An advantage in a fighting machine which is why modern typhoons are trimmed that way, and use software to compensate

The addition of more weight to the back simply made matters worse.

Ultimately spin recovery depends on getting the nose DOWN. Opposite rudder may get rid of the turn but unless the aircraft left to itself at almost no airspeed will put its nose down then you will fall off into a spin in the other direction.

Re: Negligent certification

As I understand it, the fundamental change was more fuel efficient engines. However these if placed in the logical place would have scarped along the tarmac.

So they were moved forward and cranked up a bit.

Changing the CG and the on thrust/off thrust trim by such an extent they put some software in to correct for it.

So downtrim when the throttles are opened, giving a massive nose down if the throttles are chopped. Before the trim returns to 'glide'

This was bunged in the anti stall software I think.

itzman
FAIL

Re: "How do you show who put the dodgy line of code in, and when?"

As I understand it, its not a bug, it's the whole way the thing is implemented.

They bodged the engines in at an angle, for ground clearance, and that has ruined the planes inherent stability so they are trying to correct a serious fundamental hardware fault with software.
