Heh, indeed, the similarly effective method if gamification. Even relatively "dry" things like algebra can be gamified, Dragonbox is a good example. From my limited experience (1 kid), it works really well.

True, but we can only manage 1G for minutes, and even hours is a pretty far off. Without exotic tech like anti-matter or bending space time nothing is particularly close to light speed. Even city size laser arrays are targeting 1-3% of lig

Indeed, the nice thing is power use grows quickly with clock, so even something like 5GHz vs 5.5GHz can allow a chip to run a fair bit cooler, and since there's various bottlenecks like memory latency that the performance difference wi

AMD could cap the 7600X at 65 watts, would that make you happier? Perf/watt has substantially improved, as have capability (like double the memory speed, double the memory channels, and double the PCIe bandwidth). Sure if power and coo

Drones normally have wings, or quad (or more) rotors. Powered by batteries or gas, fly rather slowly, can loiter, can collect intelligence, and have a human in the loop for target selection. Missiles typically have zero or minimal wings, p

I built labs using NCD and HP xterminals. The world was a different place and today people have different expectations. In the xterminal era they often came with minimal ram, I think it was 2MB, with options for 4 or 8MB. Mono, greyscale

Not really, for small snippets, sure. But jobs require getting something done. Sure you might be able to tab complete 10 pieces, but at some point you have to tie them together to get a working program and those 10 pieces will have differ

Maybe not, but I've done the opposite. The BMW, Subaru, and Fords I tried had terrible interfaces and I ruled them out. In particular BMW's i-drive seems to be hated by many. Tesla on the other hand has buttons for many things,

Sounds kind of like the one laptop per child project that installed internet connections for each school and each laptop could store/forward messages from home (over wifi) then upload/download them once the kids walked to school.

Anyone have recommendations for a small, passively cooled router with 2x2.5 gbe or better? Ideally with some extra ram for a service or two. Maybe the RK3588.
971.
by sliken 4y ago
10gbe and thrifty is at least for now not a good match. Could put in a PCIe dual x 10GBe card into an old PC and if that's not enough ports buy a vlan capable switch with a 10GBe uplink and enough 2.5gbe/1gbe ports for your needs.

While true, if the government downloads objectionable/illegal data and they detect that 10% of that data is coming from your IP address you'll likely have a very bad day. Sure weeks or months later you might convince a judge and&

Well think of newtonian physics. For things humans experience, it's generally plenty. Running, walking, flying, shooting bullets, etc work just fine. Sure lasers, satellites, fission/fusion, astronomy, etc start breaking things

Sure, not particularly surprising. However do you track when systemd restarts a daemon that died? See any strange dmesg errors? Had fsck report filesystem corruptions? Many errors won't cause a crash, but said errors can accumulate

by sliken 4y ago
Agreed, but ECC will prevent most of the errors from crashing the machine and tell you exactly what dimm is causing the problem. So you can replace the dimm (out of pocket or under warranty) instead of playing the replace a random part and

Not sure that's worth it. Cooling batteries is tricky, and cars are designed for high loads with high airflow. Draining a car when it's in a hot garage isn't going to be battery friendly. Adding extra cooling, DC -> AC i

by sliken 4y ago
Why bother? Not to mention the tech is changing so quickly that any standardization is going to cause problems with cooling, cable side, connector, amps, volts, etc. Maybe in 5-10 years things will settle. A few years ago charging at 550 m

Yes, gas or NG power plants can be much more efficient than a gas car that has to handle a wide range of RPMs and loads in a wide range of environmental conditions. So yes a gas or NG power plant providing power to an EV can be radically mo

If you can charge at home this is generally not an issue. How often do you drive 400 or more miles in a day? Generally I save WAY more time not going to gas stations, oil changes, smog checks, and related than I do occasionally hanging o

by sliken 4y ago
Sure. For the vast majority of daily use EVs are fine. There are corner cases, but I can always just rent an ICE if that's a better fit.

Seems silly. How long of a trip do you think you'll need to take where driving extra distance to the local battery/trailer repo, hooking up the hitch, and the power cables ... for your make/model... waiting in line/sign

Heh, dunno, seems like EV chargers are springing up everywhere. In my city they have them at various destinations like hotels, golf courses, Target, whole foods, . The city funded a few as well. Definitely more locations for charging tha

by sliken 4y ago
I just meant sobering in how cheap it is. One thing that's a bit worse for the environment is I enjoy driving an EV more and tend to drive it more than I drove an ICE. Quiet, fast ... sporty even, no oil changes, no gas station trips,

by sliken 4y ago
Indeed, I'd happily trade 1-2 gas trips a week and oil changes ever few months for waking up every morning with 265 mile range (I don't charge quite to 90%) that I only have to worry charging on long trips (over 250 miles). Doubl

A neighbor had a leaf, had a battery pack die, and was under warranty. Which dies ... out of warranty, so they bought a 3rd party replacement battery ... which also died. They ended up buying a Tesla 3 years ago, and has had no problems si

Heh, indeed, I think I've spent $50 in 2 years. But I can charge at home, although I spent 1 year at 120v. Many live in apartments and can't charge at home which changes the situation quite a bit.
987.
by sliken 4y ago
Don't forget you often can't charge when away from home. So it's more like 50 miles a day of charging not 100. Most cars charge around 3-5 miles per hour on 120v, and if you have an 8 hour job, 30 minutes for lunch, and 30 m

by sliken 4y ago
Heh, yeah, 240V/16A is 370 miles a day, 11,262 a month, or 135,050 a year. While that's quite a bit, it's a bit sobering to see that $0.025 per mile.

by sliken 4y ago
Average miles per year in the USA is 12,000 miles or so. With a ev with 300 mile range that's 40 times per year, or less than once a week. Typically a fill up in a sedan/small truck is around 75-80 kwh. So basically the cost of t
