+1 to the above.

Implementing a mental dit/dah decoder + lookup table is the shortest path to being able to decode written CW ` _ . ___ _ ` but it will cause you problems trying to receive faster CW since you can't count, assemble, lookup fast enough to receive at more than 5-8WPM. And even then you are generally doing "keyboard copy" where you write down the letters as you hear them and then go back to actually read the message you received later.


I'll put in a vote for: https://lcwo.net/ (Learn CW Online)

If your goal is to be "conversational" in CW I suggest you crank up the character speed until you are not able to count individual dits/dahs anymore. This will probably be somewhere in the 25-35WPM range. The goal is "instant character recognition" where you hear the sound/shape of the entire character rather than counting elements, assembling them in your head, and doing a mental hash lookup on the result.

If you have trouble receiving or copying down the 5letter groups at this speed resist the temptation to add "farnsworth" spacing (extra gaps between letters). Instead increase the word spacing until you have enough down time in between to get everything copied.


> most insurance won't cover DIY electrical work

You have a good source for this? I see claims like this every time a discussion of this sort and they rarely come with any citations.


No. It looks like you're totally right and the information I've shared is misleading, so let me do my best to correct that:

Insurance will pay out, provided electrical fires are covered by your policy.

They will then do their best to assign liability and pursue subrogation. If you did the work yourself, you're liable. If you're insured for that work, they'll come after your insurer. If you're not, they'll come after you. If your work is permitted and to code, you'll probably be fine, if not, good luck!

So it looks like you're correct! Unlicensed work appears to be covered, but you may paid AND sued.


My understanding of the system is that the plug is physically locked in the charge socket while the car is drawing current through the cable. Thus it is impossible for there to be arcing at disconnect.


With the Type 2 cables(common in Europe) - yes, they lock in. Type 1 cables(common in US and few other places) they don't lock in place, you can remove it even when it's charging.


Sort of. There is a micro switch that breaks the proximity pilot signal when you press the button to release the latch. That ends up cutting the power to the main pins before you unplug the cable.


> Assault charges but not physical violence? What in the world?

"The legal definition of assault is an intentional act that gives another person reasonable fear that they'll be physically harmed or offensively touched. No physical contact or injury has to actually occur, but the accused person must have intentionally acted in a way to cause that fear."

It's one of the most ridiculous charges. It's also remarkably easy to avoid: simply replace the "I'm gonna" part of a threat with "I hope someone".

Example: "I'm gonna shoot you" is legally assault in my jurisdiction. "Someone should shoot you": not assault.


More recent minivans will still fit sheet goods in the back, but they have started rounding off the lift gate (and consequently the opening it fits into) for stylistic reasons and while the maximum width is still >48" along the bottom edge you only have 42" or something before the trim starts angling up.


On the subject of the Derby, this was originally published as "The Kentucky Derby: An Oral History": https://www.newyorker.com/magazine/2019/05/20/the-kentucky-d...

Such "Oral History" articles were quite popular for a time* and the fist time I encountered this article it still had its original title. I'm sad that it was not retained since the url now gives away the punchline.

A document I saw yesterday claimed that SVB had ~$160B in uninsured deposits.


I'd love to find a good number on the daily mileage of the median passenger car in the US. The average looks to be around 30-35mi/day but the median is probably a small fraction of that. Why would you want your battery pack to be 10x oversized for your typical day?

I think a more efficient solution would be series-hybrids with small onboard generators for range extension. Minimize weight/cost of the battery pack while maintaining the ability to drive cross-country without frequent charging stops.


My understanding is that hybrids are more costly than simply putting in a larger pack. It's certainly an order of magnitude more complex.


PHEVs are certainly more complex, but a series hybrid like the BMW i3 only involves finding space for a small genset and some additional control software/electronics. I'm having trouble finding good numbers but this[0] article says the option added only ~$4k to the price.

One of the economies of battery scale is durability, no? What you gain in cost savings up front you lose by needing to replace the batteries more frequently than N times the larger battery pack size.


Where did you find those EU-27 numbers? I am seeing something around ~400B ton-km.

That appears to be "road freight" not "rail freight".
