83··on Tick-killing pill shows promising results in human trial
Almost all coated clothes use permethrin or a similar pyrethroid. It's fairly effective but I often have issues with ticks coming off my dog much later and getting on me. I look forward to this (or a lyme vaccine) making it to market - the ticks are already pretty bad this year in the midwest.

Watch for long grass along deer trails. During a particularly bad tick year (Wisconsin) I could walk along the deer trail by our swamp and just count the ticks hanging out on the ends of the green swamp grass. I did not spend much time outside that spring.

83··on Class Action Against General Motors LLC, OnStar LLC, LexisNexis Risk Solutions [pdf]
I assume LexisNexis does not provide this report out of the goodness of their heart, it must be required by FCRA?

If I really don't like LexisNexis collecting this data, or if I really just want to stay on top of my credit status, is there any reason not to script something to request a physically mailed report every day? Not sure how much they pay per mailing, but 365 of them can't be cheap.

Are you really going to wax poetic about the world's most perfect mustard and not post a recipe for your fellow mustard enthusiasts?
83··on Waymo recalls software after two self-driving cars hit the same truck
On the other hand when a human driver causes an accident one driver learns a lesson (maybe). When a self driving car causes an accident all cars get to learn from it.
83··on BMW I3 Owner Confronted with $71,000 Bill to Replace EV Battery
Here in Wisconsin the frames usually rust apart and become unsafe to drive well before the drivetrain fails. My last car made it just shy of 200k before the strut mount rusted through the unibody.

Now that I coat everything underneath with Woolwax I'm seeing much less rust, but still something you have to stay on top of.

83··on As much as you ever wanted to know about 155M artillery shell production
If it were allowed and available I bet a huge amount of Texans would be buying 155mm just for bragging rights.
83··on A Nigerian professor who makes more money welding
I don't think it's difficulty in verifying, it's just not the right tool for the job in a lot cases on an airplane. Aircraft don't use much steel, and aluminum welds typically have a heat affected zone (HAZ) adjacent to the weld which is weaker and more prone to fatigue cracking. For this reason aluminum is often riveted or bolted.
83··on There's So Much Data Even Spies Are Struggling to Find Secrets
>> Wonder if we see outsourcing to information curating freelancers

Isn't that Palantir's business model?

83··on Lightweight woven helical antenna could replace field-deployed dishes
As I understand it this new antenna changes frequencies in the collapsed/omni states so you would then need multiple transmitters/antennas on the drone which would be weight prohibitive.

Antenna tracking ground stations and diversity receivers have been around since the early fpv days, although tracking isn't very mainstream because its challenging to set it all up. I'd still prefer my dual antenna / diversity RX setup since it provides some redundancy.

83··on Lightweight woven helical antenna could replace field-deployed dishes
We already have helical antennas and most fpv is done at a high enough frequency that the antennas fit in your hand. Might be nice for 1.2ghz or lower but even there I can't see it folding down much lower than a VAS crosshair or pepperbox.
83··on eBay is laying off 9 percent of its workforce
Every year or two Ebay rewrites their UI and makes it slightly worse. I kind of wish they'd laid off a good chunk of their designers/developers three or four UI's ago.
83··on Enthusiasts struggle to keep model railway industry on track
You definitely are locked into a location. I went this route with a large basement lathe, milling machine, drill press, welders, etc and while I love them all if I ever move more than a couple hours drive away I'll probably have to sell them and start over.

I started in an apartment with the small Shurline lathe and mill and they were quite fun and capable for their size.

83··on Contra Wirecutter on the IKEA air purifier (2022)
I really appreciate Project Farm's reviews, and regularly watch them, but I often wish he had more of an engineering background. Some of the tests he comes up with fall in the worthless to downright misleading category. Not a lot of them, but enough that I wish there were someone more rigorous making these videos.
83··on Impulse Induction Stove: boils water in 40s and has backup battery for outages
If you can pay that much for a stove surely your cleaning staff will take care of it :/
83··on Impulse Induction Stove: boils water in 40s and has backup battery for outages
It's vague marketing speak, but I took that to mean now that you know the pan temperature you can monitor and not burn your garlic.

Now I'm envisioning a stove with a stalk coming out over each burner with an infrared temperature sensor and a lidar sensor to monitor the temperature and height of each pans contents.

83··on Impulse Induction Stove: boils water in 40s and has backup battery for outages
That's one of the main selling points I think. With a 3kw battery in there you could supplement the output using the battery to reduce peak amp draw, then slowly recharge it later.

Can you name the brand so we know never to buy from them?
83··on Oklahoma receives first "Made in Oklahoma" EV
I would buy the ugliest EV in the world if it was cheap and had great range. Sadly that vehicle doesn't exist yet.
83··on Active turbulence cancellation makes bumpy flights smoother
The gyros in RC are misleading. They are a sensor (gyrometer) which isn't using mass to counter movement, the are merely letting the plane know when it has shifted so it can move the control surfaces accordingly. Gyros have mostly been replaced by accelerometers at this point.
83··on Rivian R1T is the first EV to win the longest off-road competition in the US
Looks to me like mostly momentum and current carried him to a spot where his front tires touched bottom at which point he was able to spin around. He was pretty adrift until he hit that spot.
83··on Amazon reaches 10k Rivian electric delivery vans in US
Im actually pretty impressed at how much electric has caught up since i shopped for these a couple years ago, ego commercial 800 claims 800cfm at 190mph which isnt bad. I was thinking electric was still maxed out around 500cfm. Stihl gas blowers can do 912cfm at 240mph.
83··on Ozone hole goes large again
Its pretty well documented someone is producing cfcs.

83··on Amazon reaches 10k Rivian electric delivery vans in US
The cfm from electric leaf blowers are so far off from commercial gas blowers that I'm not confident they'll ever reach parity. Plus if you use high end commercial blowers you'll find that their effectiveness is somewhat exponential, that tail end of the performance lets you move a dense wall of leaves where with an electric you might as well be blowing a brick wall (I own both kinds).

You can ask them to look in a computer to find out which stores have an item?

83··on Meduza co-founder's phone infected with Pegasus
Thank you, this is the kind of insight I was looking for.
83··on Meduza co-founder's phone infected with Pegasus
Surely NSO doesn't say "hand over your exploit and if we don't already have it we'll give you millions - you can trust us".

And I would argue most trade is not based on trust, except for maybe trust in the legal system and repercussions if someone tries to screw you over.

83··on Meduza co-founder's phone infected with Pegasus
I'm curious how selling a multi-million dollar 0-day to a shady company actually works in practice. Like how does the seller demonstrate that their exploit works and isn't already in ShadyCo's catalog without giving up how it works (at which point ShadyCo could just not pay them and recreate it).
83··on Chicago’s parking meter disaster
State and federal governments are almost entirely this case, at least for technical positions.
83··on Foxconn puts its empty buildings in Wisconsin up for sale
Man, they seized people's land and tore down their houses for those. Some of those people fought back hard and lost, can't imagine how they feel about this.
