The multiplexed serial ports
As a keen QL owner, I suggested to the company i worked for that they would make good cheap programmable serial terminals for testing our X.25 PADs.
So they got one in. Unfortunately every time we connected a QL to a PAD terminal port, the PAD crashed.
We quickly worked out that the multiplexed serial ports worked by asserting hardware flow control off each time the other port was using the hardware. Unfortunately this happened at 50Hz, and our poor PADs couldn't cope with that many interrupts a second!
Still, there's a silver lining to every cloud. When the company was taken over I was in charge of a project they canned, and so was I. However as an informal consolation they gave me the QL so now I have two :-)
How to make money
From open source to $999 per developer per year. Monetising Mono seems to have worked, so perhaps PCL being open sourced won't be such a bargain either.
None, for who'd buy one of those? :-)

Did you fill in the form that tells them you're leaving the country?
If not, then I'm afraid it was self-inflicted!
Re: Sorry, being a yank, I'm missing something...
1) IR35 only catches you if you have a limited company where you own more than 5% of the shares and do the chargeable work yourself. In other words in your terms if you incorporate but don't conduct your business as a business.
2) If you're caught by IR35 95% of the receipts of your company are deemed to be income and you're charged income tax and National Insurance on them. If you're not caught by IR35 you can pay yourself by alternative methods which attract less tax and NI.
Re: Looks up, checks calendar.
Unfortunately none of those things mean you pass IR35.
The real contractor has multiple concurrent clients, does everything as fixed-price work packages rather than by the hour or day, and doesn't listen to the slightest thing the client tries to tell him what to do.
Of course this means the real contractor gets fired a lot...
Re: Magnetic Drum Memories!
I worked on a power station system in the 70s that used a pair of mag drums totalling 640K. They took all morning to back up to paper tape..
The most enduring tapes weren't paper but mylar.
I've often considered an enduring data storage medium would be holes punched in gold plates, but that has the snag that the barbarians wouldn't think of decoding the holes before they melted it down!
I wonder what data density you could get from etching bar codes using acid on granite?
Re: Government. Giant Consulting Company. What could go wrong.
x++ is another term in C for x=x+1
The extra x= makes a big difference as x++ is a postincrement and returns the value of x before it is incremented
t = x (t is a temporary)
x = x+1
x = t
My current laptop has 1TB of disc and 6GB of RAM, but I didn't buy it like that.
Just because it's a laptop it doesn't mean that you have to be satisfied with what the manufacturer installs.
I never own a laptop without upgrading the hard disc and RAM at some point in its life. The most complicated one to change was a Sony where you had to remove the keyboard, but most modern laptops have one or more handy hatches on the bottom to help with this.
And wave power is lethal!
If one were to treat the substance necessary for wave power with the same respect as those necessary for nuclear power, a 20 mile evacuation zone would be set up at all coasts!
So many people have died over the years thanks to the sea, this horrendously dangerous substance should be banned forthwith!
You simply advertise for a wunch.
Be prepared to pay a LOT of money though, let alone the bonuses...
Book DRM is counterproductive
There are a number of brave publishers out there who have been in the vanguard of ebook publishing, have published ebooks for years and don't use DRM.
Guess what they found? "Piracy" is a free marketing tool.
One publisher (Baen) even offers free ebooks from their authors, and every time they release a free ebook, sales for that author increase!
Why is this?
It's simple really, in the book trade author recognition is all. Shops will order books by authors they know in preference to ones that they don't.
So the only chance an author has of becoming known is to have copies of their work out there and gaining brand recognition. Someone can easily pick up a free copy of one of their books, then go out and order the rest of the series.
So those publishers that practise DRM are stiffing their own authors.

No user replaceable battery? Are they mad?
I also agree about the port flap.
