G'day all! That's me ... as you can tell, it's been on the back-burner for a while due to work and so on but I'll get back to it at some point and at least get our goose walking around.
@deater those look great, I'll check them out and add a link, especially since there's some lo-res stuff there! I don't recall every seeing a lo-res game other than brick out!
Thanks for the tips re: blanking interrupts, although to be fair there's no way in the world I'm going to cycle-count the entire thing ... unless ... unless ...
Anyway, such a shame there's no little wire there to trigger IRQ from VBI, it'd make so many things easier. It seems really obvious now but I guess at the time it Wozn't.
In the olden days of x86: "REPNZ SCASB" to get the length of a zero-terminated string and "REP MOVSB" to copy bytes from place to place. But I think more modern CPUs actually work faster with the RISCier equivalents.
Yep, a pretty serious piece of kit, although you really needed a monochrome monitor for it to work properly ... regular TVs didn't have the horizontal bandwidth.
Sydney's works fine. London's too, not the special one the regular tube one. Also Tokyo Narita and Schipol. What they've all got in common is that they're well connected to a good public transport system.
Well, sure, and theoretically a success gets you 2xx and a failure gets you 4xx/5xx.
But there's a layer beneath HTTP as well. If all you get back is a TCP RST, did the request succeed or fail? How about if you get an ICMP unreachable or just a timeout ... should you retry?
So, the Internet being what it is, it is probably not a bad idea to aim for idempotence for the critical bits.
What I'm a bit puzzled by here is that if I'm reading the X-axis right the rot sets in at 3 weeks ... I mean, that's not very far in. It seems odd that the graphs are both otherwise so linear.
I just EOLed a project which started 8 years ago ... at least one bug existed for 7.5 years of that. It was a minor UI bug and just bumped along at Priority Low with no-one really minding it until the company got acquired and the project got merged into another one. There were others as well.
My point is: without splitting the "backlog" by priority it is hard to see if this is really "software death" or just "bug fossilization" ...
I think also, a really top notch expert makes what they're doing seem so effortless that you do think "yeah, that's just what I would have done".
And probably you would have, at least eventually, although maybe with a couple of false starts and by that point perhaps some misfeatures have already been locked in and now your simple, elegant solution (the one you came up with all on your own without some fancy consultant) isn't quite going to work the way you'd like it to, but it's still 90% of the way there and you're only a little bit over budget -- so long as you cut a couple of the less useful features you should hopefully get the whole thing done before you lose the support of management -- but then they change CTO and the whole thing gets put on hold indefinitely.
The climb up from Whittlesea is impressively direct in places on a pushie. I've seen plenty of people do it, but it is a different kind of ride and I'm not going to try it any time soon ...
I like his GIS work, but there is no conceivable way that there were only 3 pushie accidents on that road in 7.5 years so sorry VicRoads but I doubt the dataset is accurate.
I don't know if RPF himself had anything much to do with it, but the typesetting of the /The Feynman Lectures on Physics/ is beautiful.
It features the main column / side column design as discussed, with notes, diagrams and navigation hints in the side column and is a great demonstration of the value of whitespace!
Ha, I made a thing like this back in 1994 or so out of an old monochrome 640x480 laptop screen, a couple of those plastic fresnel lenses and a whole bunch of glue and cardboard. It worked about as well as you'd expect.
I was totally into the Virtual Reality hype of the day. It's funny to think that 20 years later it might almost be useful. Maybe I'll buy an Oculus Rift to celebrate :-)
Agreed, this is a case where a small number of test cases would have been sufficient to cover the critical parts of the code and avoid this particular error and many like it.
