As long as we're on the subject, I'd like to know about such software, too, but I'd like something that's OS independent, and stores images locally. My mom has an enormous collection of family photos, dating back to the early 20th century, that I'd like to catalog while she's still around. It would be nice if she could do the annotations on her Windows machine, while I organize everything on my Linux machine. Ideally, we could copy the images and associated data back and forth using a CDROM or USB key.
"Why do you need that $700 enterprise-grade AP? Just use the $69 linksys one like I do at home!"
I just got a very similar question, yesterday.
We're adding 350 workstations (and PoE phones) to our network - something for which we should be seriously looking at a Catalyst 6500 or a Nexus 7000, right? No, I cheaped out and got some Catalyst 2960s and a pile of SF500s. Total cost? $20000.
What's the first question they asked me? "Nowadays, I can get two terabytes of hard disk for $100. Why do we have to pay so much for our network ports?"
You know, I don't even have a problem with that. I kind of feel like looking at their ads is the price I pay for viewing their content, and (assuming the ads were less intrusive) it's better than having to explicitly pay for every site we access. I held off installing Adblock for a long time, but when their ads are so CPU intensive they hang my browser for minutes at a time, that's where I draw the line.
That's because computers at the time couldn't keep up with the drives (unless you really knew what you were doing). I read a bunch of old QIC tapes I have, a few years ago, on a relatively modern machine, and the drive only stopped at the ends of the tapes.
Interrupts worked fine. It was bus errors (i.e. for off-chip memory protection and/or mapping units) that were a problem. The 68010 fixed that particular issue if I recall.
You're correct, except for the fact that it wasn't a bug. The original 68000 simply wasn't designed for use with demand-paged virtual memory. To make that happen, you need to either save the processor state somewhere (which the 68010, 68020, etc. did) or have restartable instructions (the approach used by National Semiconductor, for their 32000 series). I vaguely remember reading that Motorola switched to restartable instructions in the 68040 or 68060, but I'm not sure.
My first exposure toboth UNIX and 68K was with a Motorola VME/10 system
I've actually used one of those. Pretty decent machines, for their day. I especially liked how they had two ways to access the graphics memory: one by bit-planes, and the other by pixels.
You're lucky; my first 68K experience was on a Vicom image processor. It was a 68000-based machine, running VersaDOS. Talk about a terrible OS - even MS/DOS would have been better.
The '020 supported external memory management (MC68451)
No, the 68451 was for the 68010 - though since it was a segmented MMU (rather than demand-paged), I imagine it could have worked with the 68000, too. The 68020 used the 68851, which was a demand-paged MMU.
The 68030 could hold short loops in its chip logic with some tricks, despite not really having a cache. Unfortunately, the 68040's on-chip cache implementation was horrible and created all sorts of problems for implementers, and by then Intel chips were running much much faster
No, you're thinking of the 68010's "loop mode", where tight loops didn't require memory accesses for instruction fetches (after the initial instruction fetch). Both the 68020 and 68030 had caches.
Why would anyone want to watch someone else play video games?
Have you never heard of YouTube? Try searching for "let's play", sometime. Some of those videos have over a million views. Even the less popular stuff, like Minecraft, pulls in enough advertising money for these people to make a living from it.
Just because the author asserts that the password system is broken doesn't make Randall Munroe's point about passwords incorrect.
That was the first thing I thought of, but I still thought the author made a few good points - especially the part about wanting to get rid of passwords, entirely - and I wanted to see what other Slashdotters thought.
and this is EXACTLY what's wrong with programmers today!
I'd love to agree with you, there, but when I got started programming, VAXen were all the rage, and programmers were still taught to program as if CPU and memory were unlimited resources. Sorry, but this is one philosophy you can't blame on "programmers today."
What I want to know is, what ever happened to fuse-based proms, and why we can't use similar technology to store important data? I have to believe that, with current technology, we could create proms with a density at least as high as current usb keys, and since they're just microscopic wires in a hermetically sealed package, they'd last basically forever.
you therefore find the concept to be so ridiculous as to be outside the realm of plausibility
You need to learn how to read - specifically where I used the phrases "slightly less believable" and "most people". There are definitely exceptions to that rule.
One of the things I find makes the show slightly less believable is that Sheldon seems to be completely asexual. In reality, as far as I can tell, most people as smart as Sheldon are obsessed with sex. (Feynman and Hawking, for example.)
I find it interesting that Akamai is complaining about server vulnerabilities, when something like 30% of all the alarms on our IPS are set off by hosts they control.
Maybe that's the real reason we don't have it yet.
You're probably right about that.
While I don't really believe this, it wouldn't surprise me if, in the future, there was a big news story about how the cold fusion guys were right, all along. Why? Just think about how the world's power structure would change, if it was real. Demand for fossil fuels would drop to maybe 10% of what it is now, almost overnight... power companies would be out of business... and so on. Portable fusion reactors would dramatically transform the world, so there's plenty of incentive for the powers that be to supress such a technology.
Wow, I totally agree with you, on that. For example, one reason I've always preferred Firefox over IE is that, when it couldn't get connected to a website, it would basically just say "I can't get connected to that site". My first question was always, "well why can't you get connected?". Were you able to find look up the name? Did you get a network error, like "connection refused" or "network unreachable?" Now, Firefox is doing the same thing. Holy crap, is that irritating.
Nowhere was this more obvious than right here on Slashdot where, a few years ago, some woman (I don't remember her username) who owned a hosting company in the Bay Area was whining that college grads were expecting to get $60,000/yr. I'd be surprised if you could even eat for that kind of money, there.
Now mind you, I'm not saying that suddenly everyone should vote Republican (I'm registered as "no party" in my own state), but I want to know how the folks who support the President no-matter-what can continue the cognitive dissonance and devotion to the guy in spite of crap like this
Because, sadly, the alternative would have been worse. Do you seriously think Romney wouldn't have done exactly the same, at least as for as Network Neutrality and Patent Reform are concerned?
Even towards the end of the Bush years, you never saw this level of personality cult
You must live in a blue state. I live in a red state, and we have people here who still wish Bush was in office.
please tell me why not support someone such as a Green Party candidate
I'd love to. Does the Green party have any candidates who have even the slightest chance of getting elected?

Actually, as far as AGW is concerned, wind power has two advantages: not only does it produce no CO2, it also removes energy from the atmosphere.

Also, if you had any interest in actually looking, all the numbers you need to do the math are available on the Internet.

You missed a word: "officially".
