touch a_tset_file.txt mv a_t{se,es}t_file.txt

it works for changing file extensions:

touch foo.txt mv foo.{txt,json}

or for adding or removing characters, just leave the other side of the comma empty

touch foo.txt mv foo{,bar}.txt mv foo{bar,}.txt

This rings alarm bells for me. What are the chances that it comes with a pre-installed Android rootkit? How would you know?

But on the flip side, as a gamer, I couldn't imagine giving up my discrete graphics cards on my gaming desktop. How many years back and how low resolution and graphics settings do you have to go before you find a game which is playable on an integrated chip? I guess it depends a lot on your definition of "playable", and your game selection; if GOG is where you regularly buy games then the integrated chip is probably more than adequate. Or if you're using a single 800x600 monitor, you're probably ready to run the latest games on your integrated chip. But otherwise, I can't seriously recommend anyone play games on an integrated video chip.

Sidenote: I would choose the touchpad as my #1 source of hardware frustration. Anecdotally, I haven't had much issue with graphics cards, other than one replaced under warranty.

When they first put it in, I noticed there are 3 or 4 of those in-road "buttons" (weight pads?) right in a row under the toll platform. They could be used to trigger the timing of the reader and camera, or I figured they could be used to determine speed quite easily.

So for a while after it was first put in, I would carefully hit my brakes and ensure my speed through the toll was right at the speed limit, then go back up to normal speed. But after a while I got lazy and stopped doing that, since nobody else appeared to be doing the same. "Everyone" was speeding through it.

I never received anything in the mail, and nowadays I rarely go through the toll. But now this article makes me think I could have been right, maybe they are recording speeds (or capable of doing so) and just doing nothing about it.

I don't believe their claims that it will last 3 years of regular use, that it will have 1500 charge cycles, or that it has "novel battery chemistry". I'd give it up to a year, and even then you'd probably be experiencing much lower capacity by the end of the year, but that's my rough guess. I'm also a bit surprised that it's deemed safe for consumers and will be certified.

Gassing (or smoke, not sure which) starts around 15 sec. Plenty of results for 'LiPo explosion', 'overcharge lipo', etc.

A LiPo fire is a chemical reaction, it cannot be extinguished by traditional fire extinguishers (i.e. smothering does not extinguish, it's creating its own fuel) -- you have to wait for the battery to burn out and then extinguish the remains on fire. Treat your batteries (and electronics with batteries in them) well, folks.

I feel like you've mixed up LiFePO4 and LiPo. LiFe has low charge rates, lower energy density, lower voltage, and higher cost compared to LiPo. For R/C aircraft, it's typically used only for the receiver and servos of the really large helis/planes, because its lower voltage is tolerated by the servos whereas a LiPo needs a regulator to step down to 5-6V for driving servos. I can't speak for expensive hand tools, but "everyone" in the R/C community uses LiPo.

As a result, I end up missing or not doing things, and re-reading emails I've already done, and my inbox is just a big chronologically-ordered mess.

This is my personal email anyway. My work email I'm a little more careful with, but it also piles up over time and rarely something will slip through the cracks. Outlook's flag/reminder system is decent at least, so it's manageable, but it still at times feels disorganized and just not quite how I want it to be.

I used GRC's DNS benchmark tool to discover this. Also the particular OpenDNS servers which responded faster were different from the two that they tell you to use, so the fast response is probably helped by low load (fewer people using these undocumented servers). Going from memory because I'm at work, I think they ended in 202.222 and 222.202 and 202.123, whereas the officially listed ones end in 222.222 and 220.220.
