paulkrush··on Challenger Hellcat Redeye Turnkey Engine Swap [video]
This is an awesome visual representation of Python throw away glue code I write. This even extends to some of the hardware projects I do. Some people might be embarrassed to say this, but I feel it's just really efficient.

I never used this one, but I had one of the first Kodak cameras. They had an awesome API! I saw someone play PacMan on one of the early ones.
paulkrush··on Via ferratas are finally catching on in the United States
Great video on a free one in Colorado: https://www.youtube.com/watch?v=bReTV2J7PIk

"Telluride Via Ferrata in Colorado has been on our bucket list for quite some time. So when our cousin Anh asked if we want to make a trip there, of course, we said yes. Telluride Via Ferrata has to be one of the most exciting and unforgettable adventures. It combines mountain hiking with the traditional Via Ferrata cable system and breathtaking scenery. There is nothing more thrilling than traversing across a sheer cliff, 600ft above ground, with only safety tethers, a steel cable, and metal rungs to support you. Besides the spectacular views, this amazing adventure also challenges your physical and mental fortitude while giving you an incomparable sense of accomplishment."

Mushrooms Too: https://www.youtube.com/watch?app=desktop&v=I5F_CRi8gbA Faking this would be a good use of pass-through VR. Use real multi-spectrum false coloring and segmentation to turn your yard into Pandora. In 10 years cops are going to be finding syringes with needles in the park from people injecting plants. It's going to spur a new game where people hunt and collect these syringes for "VR points"...
paulkrush··on A walk through Chicago Pedway (2017)
I used to live in the middle of the "The east side" and the pedway is really cool. If you're brave, there is way more walking complexity than just the pedway. Upper right on the map has 3 levels of streets and the bridges have 2 levels(with pedestrian sidewalks). Its kind of dark and seedy to walk on the bottom levels. At the middle level you can walked to the river walk which is nice. Going to the lake is nice. Really no retail underground, except for Billy Goat Tavern on the other side of the river. There are the ghosts of the Blues Brothers driving by on Wacker...
paulkrush··on The underground world of hobby tunneling
A friend of mine said in Moscow Russia people use to dig basements under precast concrete car size storage units. Every once in a while the the whole unit would fall in the hole halfway or more.
paulkrush··on The underground world of hobby tunneling
This is awesome Sandland got some mainstream news. I look at them as a hackerspace with professional members, and sometimes mining engineers. Not mentioned is City Museum in St Louis. They let little kids roam the tunnels!
paulkrush··on Fell Asleep in Vision Pro
Wow interesting read. I am sure it might be a little one sided, but this is still a great data point.
paulkrush··on The Return of Drum Brakes
Tires are a big source of fine black particulate matter. It's even worse when your son is trying to create large mathematical symbols in the parking lot.
paulkrush··on Apple Vision Pro review
Peak Blackberry was 2011. It's easy to forgot that that the iPhone takeover took years and many releases.
paulkrush··on New Lithium Battery Tech (HN do your worst)
HN guidelines are to keep the title the same. See the link below.
paulkrush··on Vision isn't what you think it is – see for yourself [video]
There is a lot going on here! I did not know about the night time center blind spot. See https://en.wikipedia.org/wiki/Blind_spot_(vision)

I think it's cool when you move your eyes across white LEDs you can see them break into their primary colors(depending on the PWM).

paulkrush··on Vision isn't what you think it is – see for yourself [video]
Hey this is really cool. They are "xx xxx" out text everywhere except where you are directly looking at. And it looks mostly the same. I would expect this, but it's cool to see someone doing it.

So the human brain adds detail. Literaly stereotyping...
paulkrush··on A site that tracks the price of a Big Mac in every US McDonald's
+1 for https://taconomical.com/ Texas is really divided.
paulkrush··on Images altered to trick machine vision can influence humans too
I find sci fi or satire with a bit of truth in this area far more interesting than any serious attempt.
paulkrush··on 2TB microSD card is on the way early next year
A wild guess of 3.5" floppy production is 30B. So you need 21,428 2TB micro SD cards. A 15mm x 11mm x 1mm you need 3 1/2 liters.
paulkrush··on An underground delivery train comes to the Atlanta suburbs
Wait, they can literally send a Subway pork sandwidge in a pipeline pig... That's funny.
paulkrush··on An underground delivery train comes to the Atlanta suburbs
So they can send up to 40 bananas in a pipe rover going 45mph... Hyperloop for lunch sounds like a good idea to me.

paulkrush··on Coordinate Precision
And if you search the lat/long he uses:

The more precise coordinates are actually in the middle of the Rocket Garden at the Visitor's Center of the Kennedy Space Center complex.

The atom-level coordinates are obtained by appending digits of e and pi to the Rocket Garden coordinates.

paulkrush··on Tesla Cybertruck vs. Porsche 911 drag race
The Cybertruck beat the 911 while also towing another 911. I am not a fanboy of ether, but this is pretty cool from an engineering standpoint.
paulkrush··on Process for mass producing Japanese 500 yen coins
I am envision them still running a 1999 VB6 app ported in 1999 from an old DOS Fortran EXE to calculate the exact kilos of pure metals to compensate for alloy composition differences as they melt the scrap crucible to keep the alloy in spec.
paulkrush··on Ask HN: What paper/print magazine do you still buy and read?
All things I buy and read: Banknotes, food containers,instruction manuals, blank paper, boarding passes(once in a while), sometimes newspapers from packages, and non-free guide to an attraction. I am guessing you mean "periodical"? A calendar. Technically... a workout club magazine that I keep forgetting to cancel.
paulkrush··on Ask HN: Are there any good sources of randomness in the human body?
Guess too precise of a measurement, find a median, and use over under.
paulkrush··on Ask HN: Are there any good sources of randomness in the human body?
Listen to the internal sounds of your body and find something that can be compared against a counter in your head. Passing a finger along your skin slowly will jump at random intervals. Can two people trigger each other?
paulkrush··on Ken Griffin sees Miami possibly replacing NYC as finance capital
Yes! It's clear Miami will have plenty of liquidity as sea levels rise. I guess they are both on the coast, but would rather be below sea level on rock over sand.
