Comment Network file transfer (Score 1) 466

Windows 3.11 machines were capable of SMB file sharing over a network. You should be able to use an old PCMCIA ethernet card and install the Microsoft TCP stack (it wasn't installed by default), then see other computers over a workgroup.

If that sounds too hard then serial transfer over null modem should be the easiest and I'm sure I did it many times myself back in the day. I cant remember what software I used to use, googling for Windows 3.11 serial file transfer shows lots of hits though.

Comment Negative feedback loop (Score 1) 389

So, robots start replacing jobs because they can make widget X cheaper.

As unemployment increases, less poeple will have the money required to buy widet X. The manufacturers will have to lower prices in order to get sales, and their cost reductions through robots will evaporate. Meanwhile everything just got cheaper.

At some point we'll reach equilibrium again, where the cost benefit of adding a robot will be balanced by the lack of sales due to poeple not having an income. It might be painfull for a while until we get there, but it will happen.

Comment Re:Equally tiny UPS? (Score 1) 180

These low power PC's are opening up new opportunities for UPS's, namely that they all run off low voltage DC (nominally 12V) and open up the possability of a 12V UPS. It saves on the inverter required in the UPS, and increases the overall efficiency.

For a device like this with a variable input voltage you can run it directly from a 12V SLA battery, and then keep the battery topped up with a decent mains charger rated to higher power than the PC. You can generally do the same thing with access points and 12V network switches, and any 5V devices can be run from a $5 step down DC-DC converter.

The only problem I've had with this method is 3.5inch USB Hard Drives, as they usually require a well regulated 12V supply. For those I bought a fancier buck-boost DC-DC converter, they were a little pricier and harder for find than, but still quite reasonable.

In the end you may have 30W worth of devices hanging from the SLA batteries, then just buy a multistage charger rated to the next higher power - eg 30W = approx 2.5A @ 12V, so get a 3 or 4amp charger. You can expand to as many parallel as you like, all it does is slow down the recharge time.

Comment Re:Ocean Seeding (Score 1) 319

I've seen studies on that before.

One of the best ways to seed the oceans is with the addition of iron based minerals. Plants in the food chain need this to grow, but it's very scarce in the ocean. Historically there was a natural seeding process as iron laden dust was blown off the coastlines, but human development has reduced that source.

In Australia we get a Strata Title deed, with common shared assets managed by a strata management company.

For simple blocks subdivided into a few houses, the homeowners can form their own strata company with little to no costs. For apartments buildings they generally employ a third part to manage it, and residents will then pay monthly strata management fees.

I used to build & configure production reporting systems for industry, and the increase in complexity on the math was freaking painful when you had to take in to account daylight savings. Instead of assuming 24 hours in a day, you would always have to calculate "day end minus day start".

These methods would handle leap seconds just as well, but the cost to performance is massive for such a rare event.

Comment Re:Home of the brave? (Score 2) 589

It was a terrible situation but to put things in perspective, this kind of incident is incredibly rare in Australia and only 2 poeple died. If you had concealed carry, there would be orders of magnitude more accidental deaths. Doesnt seem worth it and the gun controls we have here generally do a good job.

Not true. At those powers, a reflection of any surface can be powerful enough to blind. There will be a lot of collateral damage.

Just remember, lasers in the milliwatt range can do permanent damage and this thing is 30kW. It would only require 0.001% of the energy to be reflected - you can get that much off a black surface, let alone something shiny.
