The emulator developed by Smith and Andrews seems pretty good, at least on YouTube. When they left RCL, they took it with them.
RCL then had to find someone else, and went to Planet Computers. They took FUSE and hacked around with it but, for whatever reason, it wasn't finished.
It was originally planned to custom firmware, this video, from eleven minutes onwards.
Why Sir Clive Sinclair’s corporate shareholder in RCL, Sinclair Research Ltd, has not intervened is a source of ongoing confusion
If SRL voted with Andrews and Smith to kick Levy & Co. out and take their place, that would mean they have to spend money winding RCL up and become responsible for the debt while trading insolvent and possibly whatever else Levy's done in everyone's absence.
I guess Clive couldn't be arsed with that.
I used to have that view, but years later found out that 6502 page zero access was treated specially and very fast, effectively giving another 256 registers.
But then again you have to do stuff like reset the carry flag before operations meaning the code size was bigger, and there were fewer conditional jump commands available after you'd done your operation.
That kind of stuff would get old quickly (as you can guess I learnt Z80 assembly).
the 2MHz 6502 in the BBC performed tasks faster than the 3.75 MHz in a Spectrum.
The memory access was also more simple for 6502, which enabled it to work with slower memory than the Z80, mainly because memory and CPU clock speeds were linked together.
The BBC had 4Mhz memory multiplexed between the 2Mhz CPU and the video display, so the CPU always never had to wait to access the memory.
The Electron on the other hand had the same 2Mhz CPU but used a contended memory model (similar to the Spectrum). When the video output needed to access the memory, the CPU was paused. On the Electron this meant the machine was pretty slow, far slower than BBC and slower the Spectrum. Unlike the Spectrum, it had no uncontended RAM area.
This is the most thorough review I've found so far.
So, rather glad I decided not to go for it.
I'm usually taking the mickey when I use that subject line, but here I'm not. Surely the figure will increase above 89% as the 70 and 80 year olds who have never used computers drop off their perches, and nearly everyone who is alive will have had some computer experience?
Is going from not using a computer to using a computer badly an improvement?
Nobody's talking about overloading. If you are juggling a bunch of void * variables about and calling a bunch of functions which accept void *s, or you are forced to cast to void * in the function call, you can pass the wrong variable to the wrong function. However, if you define the function to accept an opaque structure pointer instead of a void * then the compiler will enforce type checking and you can't make that mistake.
Or you don't understand why void* exists and why its sometimes required as a function parameter.
Okay, so tell me why I'm wrong and what your example is.
You can just as well use an opaque structure instead of void *, it makes the code more readable and unlike void *s the compiler makes sure variables aren't passed to the wrong function.
And that works with callbacks too. You don't even need to cast it to something else in the callback code, just define the structure fully instead of opaquely in that .c file.
There's a new data type, called unknown, that differs from another catch-all data type, called any. "Unlike any, unknown is assignable to almost nothing else without a type assertion," explains Rosenwasser. "You also can’t access any properties off of an unknown, nor can you call/construct them."
In my experience, whenever there is a question, and void * is the answer, either the answer is wrong or the question is wrong.
I have no idea why repeated viewing of terrorist material should be illegal, yet Facebook and YouTube can keep it up there indefinitely.
The only reasons that come to mind are a) MPs have been lobbied by Google, Facebook, b) civil servants don't know how to draft the laws, or c) the data will be used to compile watchlists.
a) requires a less corrupt democratic system, b) PPE and classics graduates have no idea about anything technical, and in this age this is unworkable and they must get outside expertise in, or c) that doesn't work for preventing radicalisation, people get radicalised anyway, there are too many to keep tabs on, the material must simply get taken down.

So ... what is going on?
Politics. Another SPD-CDU coalition has decided to migrate to Windows, this time before the cost-benefit analysis has even come out (wonder who's going to write that one anyway):
Windows scores a win over Linux as another state decides to switch
The Munich decision was made by the city's ruling coalition of the centre-left Social Democrats (SPD) and centre-right Christian Social Union (CSU), a party that only operates in Bavaria, and that is the long-running junior partner to Angela Merkel's Christian Democrats (CDU).
Again, Lower Saxony is governed by an SPD-CDU coalition, which was formed last year with an agreement that included turning the state's back on Linux. Other administrative departments there, including the police, are already using a Windows 8.1-based client developed by a local company.
Lower Saxony's tax authority will now conduct a cost-benefit analysis on the migration. The Free Software Foundation Europe (FSFE), which is highly critical of the decision to turn away from Linux, welcomed the procedural formality, but program manager Max Mehl said it was important to keep an eye on who conducts the analysis.
The Munich migration followed the recommendations of a report from consultants at Accenture, a Microsoft partner.
"It is already apparent that the desired consolidation of the IT landscape is going in the wrong direction," said Mehl. "Instead of taking the chance to expand the existing infrastructure of Linux systems, the state voluntarily goes back into a cage of artificial dependencies from individual manufacturers."
Mehl pointed to Lower Saxony's neighbour, Schleswig-Holstein, for an example of a more "future-oriented IT strategy". Schleswig Holstein has been governed since last year by a 'Jamaica' coalition of the CDU, the Greens, and the liberal Free Democrats (the party colours of which match the Jamaican flag), which decided last month to go in entirely the opposite direction, abandoning Windows for free software.
There's a weird customization option that does nothing more than put a little watermark on your ribbon, eg a little swirl. Maybe 10-12 choices here. But for the love of god, why?
If it were user definable, I could put the design that best suits the kind of corporate e-mail I receive, i.e. Munch's The Scream. However it isn't, so I just leave it blank.
