On-campus DC networks don't count against the bandwidth limit, and torrents are blocked. The network is 100Mbit in some places, 1Gbit in newer and renovated areas, so transfers are obscenely fast.

Just the other week I helped my mom delete her Yahoo email account after it was hacked and sign up for Gmail. I kinda thought that most of their userbase was people like her, who only used it because it's what they've always used. Why would anybody ever want to possibly sign up for a new account there?

Before the satnav receiver, there was the Jones Live-Map, first sold in 1909:





This was a large odometer wheel on which a paper disc was mounted that gave directions for a specific route between two cities. At specific distances, it would have marks on it that said things like "turn right after bridge," "watch for dangerous curves," and so on. Each disc covered a hundred miles of road, so for long trips, one would use multiple disks, purchased from The Touring Club of America. After ten years, there were 500 routes available.

Personally I haven't used DCC* since 2006, but used it regularily from 2003. Since then I've only used file lockers (and rarely torrents).

I never used IRC (only had 56 kbit/s line until 2003) and it was $1,5/hour.



Edit: Ooops I guess DC++ is something else (P2P)? Never mind.

I periodically use certain channels on EFnet to grab random songs I want to listen to. Most of the time they end up being non studio versions or crap out halfway through. Since I'm almost always connected to EFnet anyway it's no great loss.

I know I still use a lot of Yahoo for most of my email stuff, and prior to that it had been Hotmail and I know I ended up making a few side accounts over the years there just for random websites and contest entries.

I just never felt really all that in a hurry to make Gmail my primary Email account and mainly only use that as a means for being able to access the Play Store or watch videos and red band trailers on Youtube that make me swear I'm over 18.

I know one of the big complaints/concerns about the Yahoo plan of recycling addresses is the potential for identity theft and privacy issues. Despite having your old account's emails deleted, a person who scoops up your old address could just as easily start to go around to a lot of popular sites and do a password retrieval for them to see what sticks and what they can glean.

We had something like a split flap displays for years around our town. They were large and instead of letters or numbers, they were just 'pixels' that would flip to green or black little paddles to form out a single long line of letters, numbers, and very simple symbols.

Standing beneath the sign was like hearing a thousand little claps going on ever 3-5 seconds at each change. Chlap! Chlap! Chlap!

Just looked it up, that type of sign is called "flip disk", makes sense.
My university used to have one of those for displaying the time, temp, events, etc. We called it "kachunk" and it was used until around 2009.

As far as power semiconductors go (diodes, SCRs, IGBTs), depending on the semiconductor not only kilovolts, but kiloamps of current. (I worked with SCR pucks that could handle around 1500 amps at several hundred volts.)

In fact the new big thing for power transmission is ultra-high voltage DC transmission, only possible with advances in power semiconductors. So you have one power line at +500kV and another at -500kV, and the difference between them is one million volts!

DC transmission, once a mad pipe dream of some rear end in a top hat named Edison, is becoming a reality because we can actually do useful things with DC now. Changing DC voltage is now a matter of solid state voodoo versus having to use two DC motors of different voltage coupled together mechanically.

It will have advantages over AC such as no AC line losses and doing away with syncing issues between various grids. Also less wire, as I have heard of them using single conductors at 1MV and the earth as the ground. Smaller wires, less wires because higher voltages and less losses? Yeah, I think the future is going that way. So, Edison, you lousy shitbag inventor, your mad dream of DC is comin true, although AC is still better for a lot of things.

A sub-1Hz refresh rate, so it couldn't update to one second before it had to move on to the next one. It's generally not a problem with nixie tubes, but it's not an unreasonable thing to think about.

This was posted a bit upthread, but it illustrates the (potential) problem perfectly. See how it can't display a seconds field that ends in 1, because it takes too long to update? Same deal.

A (alphanumeric, in your example) split-flap display, one of the slowest refresh-rate live displays can't display seconds perfectly well, no... but that is not at all related to Nixie tubes. If the one in the example you posted was just the digits, it would work fine, despite being extremely slow compared to even an old slow LCD.

Nixie tubes are electronic and have the most instantaneous refresh you can achieve because there are no phosphors, no electron-hole recombination lifetimes, no liquid crystals to twist around, no thermal mass to heat or cool, and no charged beads to re-position in an oil capsule.

Ah cool. I didn't word it well but not knowing their refresh rate (or in fact anything about how they work) I thought it potentially possible that they would update slower than seconds.

I suppose I should have just googled it real quick but it's the weekend and I work 10-12 hour startup days during the week so

This is pretty similar, not old or obsolete, but cool. It's flip dot, and just listen to that sound. I want to play conways game of life on it.

Not to mention entirely practical, too. (edit: for its time.) I guess all you'd need is a couple of signposts along the way that say "Calibrate Now" or something, where you adjust the disc a bit to a marked calibration point (in case the odometer reading got skewed along the way).

Well, I guess you're screwed if you turn off the marked route for some reason. But still.

A more recent travel aid is the Traveller, a digital route finder:



Like a modern satnav receiver, it would calculate a route between two cities. It gave directions for each individual road intersection, and the driver would then press a button to advance the directions to the next intersection.
