Having done this… - don’t make your camera the highest thing around. My dome was showing scratches. Eventually I got a nice photo of the inside of a juvenile bald eagle’s talon. A bird’s gonna perch where a bird’s gonna perch. Sacrifice s

In my experience, the hubs listed tend to be obsolete. For instance, that LinkSys one I just looked up and its manual is copyright 15 years ago. Someone on Amazon is boldly offering to sell you one, a 4 port USB 2.0 hub, for $72, but whethe

Or https://www.dryicedelivered.com/ I wonder if they pack it in dry ice to keep it cold while it ships? Edit: They do.

It works fabulously. If a McDonalds has a "broken" milkshake machine it most likely means the workers did not maintain it in a hygienic manner. Stop eating food from that store. Requiring these machines in the stores is a hidden g

If you live some place with a winter, you will have a barren patch of dirt then. If you live somewhere with a long, cold, wet fall or early spring, then you hill have a tiny field of mud for the local animals to wallow in. If you live withi

0 mi in 4 guesses. The funny part was I forgot to look at the photos after the first two and had to go back and look at the photos to see what I missed. The first photo has a bridge, so that informed the clicks a bit since I knew I needed a

In this case, Swift is being, lets say suboptimal, compiling an 8MB array of integers. It's worth mentioning another, more common, cause. There can be computational cost explosion when Swift resolves the types for function calls (and o

Maybe we should take a page from farm subsidies and have pharmaceutical subsidies where the government will buy some quantity of expired inventory of important medicines. Price it at kind of the low end of what insurance companies would pay

I've seen it a couple times, but not with Apple cables. Some of the 3rd party cables have the exterior metal of the connector just sort of snapped/crimped/pressed on and that pulls off to be left in the socket. You have to d

It's a fundamentally unsolvable problem. There exist names with multiple valid pronunciations for the same spelling.

People don't have much feel for sound decibels. This is going to be loud, but for context, both "The Who" and "Deep Purple" have played concerts that were louder than the sample and thunder (which animals are expos

Ultimately, maybe not, but I finally dabbled in geolocation on a property that was receiving comment spam. I ended up eliminated 100%, not nearly 100%, actually 100% of the spam by blocking anonymous content from one country. In another app

I have failed to find the parasitic draw on an RV (slower than this one, it takes a couple weeks to kill the battery). I finally got a "Top Post Battery Master Disconnect Switch", which is a little dinglebob that goes between the

In the US you are unlikely to get metric threaded legs at a local hardware store. But yeah, knobs are knobs. From time to time I help assemble scores of tiny Ikea dressers for a charity. About 1 in 6 ends up needing rework because something

That “farmland” number is next to meaningless. The vast majority of animal land is useless for other agriculture. If you are visualizing a green grassy field full of cows, that is nice and they might even support one cow per acre (2/h

A billion is three groups of three zeroes. So for visualizing I would think of a cubic meter compared to a cubic millimeter. A grain of sand serves for a cubic millimeter. For the cubic meter you can either visualize a cube that size, or

As you get to small image sizes, the relative size of the quantization table and the Huffman encoding table becomes significant. You can easily just pick a standard version of these, leave them out of the image (which is no longer a valid J

Superglue has a shelf life of about a year before it stops working as well. It will still harden, but doesn’t have the same strength. I figure it’s six months old when I buy so in practice that almost always means “buy a new tube” if you n

I see that after 50 years, C has finally gained an official null pointer value and type! "nullptr" and "nullptr_t". That wouldn't be so interesting, but it highlights the complexity of specifying a language and im

I drove a Rabbit Diesel back in the early '80s. It was not a luxury driving experience, but 48MPG highway! I didn't have much money and squeezing in a 700 mile round trip would let me visit my girlfriend over a weekend. Lots of mi

There was a pretty good time interval between dot matrix printers becoming a thing and any kind of dot addressable graphics. For many years you just sent them regular old ascii codes and got text. I think communication interfaces had to com

I went through part of this while working on some liveness analysis. The lecturer and the notes do a good job of conveying ideas. Well worth using as a resource.

I suppose things might have changed in ~half a century, the FDA used to care about everything. Back in the late '80s the VAX-11/750 that was part of the Siemens MRI scanners was shipped in the old blue trim color long after DEC ha

I'm beyond my expertise, but silicon crystal's compressive strength is 3GPa, so maybe? Plus I assume one would surround everything with a "fluid" (or at least flows at that pressure) to distribute the forces. Silicon chi

A woodworking clamp with a handle in line with the screw will generate about 400lbs of force. That’s a reasonable model for how much axial force you will be able to exert with a screwdriver handle and beefy threaded screws. To get 150000 p

There are tax credits to the builder to offset some of the increased up front cost, $2000 + $500 for some systems, and 22% on PV systems. It looks like the homeowner can get a $5000 tax credit for 10 years. The goal is to transition to hous

Yes, for those unfamiliar, the city used to contract to have waste oil sprayed on the unpaved streets to keep the dust down. (Hush Children of Summer, it was the 1960s and 70s, it seemed like a good idea at the time.) In 1972 their contract

More anecdotes! I use the AirPod Pros many hours a day and have mild tinnitus. I find the noise canceling makes me more aware of the singing in my ears. I don't live in a place where silence happens, but the cancelling will kill the ou
