tsomctl··on OpenStreetMap in Realtime
Speaking from personal experience, being a passive-aggressive asshole doesn't solve any problems.
tsomctl··on IBM quantum computers now finish some tasks in hours, not months
I'm thinking it's this: https://en.wikipedia.org/wiki/Swords_to_ploughshares
tsomctl··on SoftBank’s plan to sell Arm to Nvidia is hitting antitrust wall around the world
ARM makes their money by licensing the design to other huge companies, who then integrate the processor with other peripherals and manufacture it. They have no interest in extracting money from the end user, instead the documentation is readily available. In comparison, Nvidia, for example, sells you a video card, then you have to pay them again for a license to do deep learning. Oracle requires the end user of Java to pay a license to use the JRE. The fear is that if Qualcomm or Nvidia buy ARM, they're going to turn ARM into a similar business model where they try to nickel and dime the end user for everything.
tsomctl··on SoftBank’s plan to sell Arm to Nvidia is hitting antitrust wall around the world
Are you annoyed that he's being negative, or because he didn't back it up with a reason?

Because I've done development both for embedded arm microcontrollers and CUDA. ARM feels like a benevolent overlord that wants to help you. Documentation is open, compilers are easily accessible, there's lots of random blogs with best practices on how to do common operations. Nvidia feels like their entire goal is to extract as much money out of you as they can.

I'm not hoping ARM fails. I'm hoping the sale fails, because if the sale succeeds, ARM will fail.

tsomctl··on Toyota's game-changing solid-state battery en route for 2021 debut
Thought I saw a Jalopnik article about Bentley or Rolls Royce inventing that exact thing, but I can't find it now. The idea being, if you're a billionaire, you don't want to do something low class like plugging in your car.
tsomctl··on Some Tesla Model 3 rear windows shatter spontaneously
I'm sitting in an office chair, not an armchair, but I'm thinking the steel frame it was glued to flexed. The inside pressure theory doesn't make sense. Modern cars are well sealed, but you still have flaps at the back of the car to let air out, and they are loose enough to let air in.

tsomctl··on Laptop stolen from Pelosi's office during storming of U.S. Capitol, says aide
I was providing counter evidence to:

> I've also heard that the congressional paging system locks devices when an emergency is announced

If computers locked automatically when an emergency is announced, it doesn't matter if the staffers evacuated quickly.

tsomctl··on Laptop stolen from Pelosi's office during storming of U.S. Capitol, says aide
Counter evidence: the protesters were saying that they saw computers unlocked with email still open.
tsomctl··on Texas Instruments sent a DMCA takedown to a site archiving data sheets
It's a perfect example of the general shittiness of life. Just little things that, in of themselves, aren't bad, but they add up to make everything more difficult.

Once an IC is designed, the datasheet doesn't substantially change. It isn't a computer program that gets continuous updates every couple of months. They might add some errata for some corner cases or clarification. What happens when the IC is discontinued? I still need the datasheet, so I can understand the circuit when finding a replacement IC.

tsomctl··on Truck Art in Pakistan (2018)
Somewhat related, the Youtube channel Pakistani truck (https://www.youtube.com/channel/UC64FbxoHfUWd5hykYk5_BvQ/vid...). Here's a good example video: https://www.youtube.com/watch?v=9E3TnJX61Oo

It's absolutely amazing how good of work they do using ridiculously crude tools. Extremely skilled people. I strongly recommend you don't watch if you're a manager or OSHA inspector, though.

tsomctl··on ‘YouTube recommendations are toxic,’ says dev who worked on the algorithm (2019)
I've been loading the Youtube homepage every 15 minutes for the past week (I've been sick). It's the same videos over and over again. If I scrolled past it the first time, I'm still going to scroll past it the 100th time I see it.
tsomctl··on Lode Runner
Swap disk trick for the PlayStation 2:

Find a game disk that was a demo (like from a magazine). It must have a main ELF, that would then launch another ELF from the disk. (For example, the main menu would be one ELF, and then each demo game would be another elf). Create an iso, then replace one of the game ELFs with whatever executable you wanted. The resulting iso must have the same layout, with every file at the same location. Burn it to disk. Tear apart the PS2 and remove the top of the disk drive. There's a little white plastic piece with a magnet that clamps down the disk, remove that from the lid of the disk drive. Put the original disk in the drive, clamp down the disk with the magnet, and boot it up to the menu screen of the demo disk. Without hitting the eject button, use your finger to stop the drive, lift out the original disk, set in your burned one, put the magnet on top, and choose to run the game that corresponds to the ELF you replaced. Voila.

tsomctl··on NASA's Through-Hole Workmanship Req (2002)
Flux, practice, flux, good tools, flux, good lighting, flux.

Really, learning how to braze and weld steel helped me a lot. Heat control is extremely important. Heat flows, and you learn how to position your iron to get the heat where you need it. You can also tell how hot something is by how the puddle looks.

So what, you have oiling or cooling passages immediately behind the seal?
tsomctl··on LiquidPiston's “inside-out” rotary X-Engine wins Army research contract
A picture is worth a thousand words. (Well, video in this case)

I still don't understand how it seals better than a Wankel. I understand how it's turned inside out, and it's very clever, but it seems like it would have the same problem with seals.

tsomctl··on Electric Monarch tractor can plow a field without a driver and run for ten hours
I guess I’m not articulating myself well, because I’m basically agreeing with you.
tsomctl··on Electric Monarch tractor can plow a field without a driver and run for ten hours
Hundreds of hours, perhaps. But not for the entire life of the engine. If a modern passenger car engine could put out 200 hp nonstop for years on end, every semi-truck manufacturer would be putting a BMW engine in it, instead of a huge cast iron Cummins. But I'm pretty sure you'd spin a bearing, or wear out the cylinder liner, or burn a valve.
tsomctl··on Electric Monarch tractor can plow a field without a driver and run for ten hours
There's a difference between peak horsepower output and continuous horsepower output. A normal passenger car might be able to put out 300 hp, but only for a short period of time before blowing the headgasket (or destroying the drive train). Diesel engine with gobs of torque or electric is going to produce that power at a lower speed and more efficiently, so it will be able to do it longer. Being able to put out 70hp nonstop for hours on end is nothing to be ashamed of.
tsomctl··on South Africa's lottery probed as 5, 6, 7, 8, 9 and 10 drawn
Believe it's a reference to Mike Flynn endorsing the idea that Trump declare martial law and suspend the constitution to rerun the election.
tsomctl··on Romain Grosjean walked away from F1’s scariest crash in decades
I'd say it's didn't necessarily fail, it was just a bad design. It consisted of steel posts in the ground, with stamped steel sections running horizontally. Grosjean's car got wedged in between two of the horizontal rails. It actually succeeded in stopping the 150 mph car from flying off into the desert. In comparison, a smooth concrete barrier would cause the car to just slide along it (hopefully).
tsomctl··on Ham Radio Needs to Embrace the Hacker Community Now More Than Ever
Don't bother with technician class. It's pretty easy to get your general license. There are multiple websites that have flashcards for the exam questions. Amateur extra is actually a lot of work, but general class allows you to do most things. And you can get a used Yaesu handheld for a hundred dollars off eBay. Upgrade the antenna, and that'll allow you to do a lot of things.
tsomctl··on Bluetooth Attack Can Steal a Tesla Model X in Minutes
I dunno. I have a 30 year old 4Runner. Any key from any Japanese car will start it. Or a screw driver.
tsomctl··on Uniquely Identifying PCBs, Subassemblies, and Packaging
If anything, tamper detection is extremely important for things like CT scanners and nuclear warheads.
tsomctl··on Power-cycling a USB port should be simple, right? (2017)
Have a mosfet between the 5 volt regulator and the device. At 20 milliohm, drawing .1 amp, that's only 2 millivolt drop. Or, since it's a low volume design, just throw a relay in there.
tsomctl··on After losing my savings as an indie hacker, I can't do it anymore. I quit.
Speaking as someone that used to have a major problem with depression and anxiety, an important thing part of recovery is realizing that the shit you're worrying about isn't that important. Having other people tell me that the thing I'm worrying about isn't worth the anxiety was important.
tsomctl··on Steve Bannon’s show pulled off Twitter and YouTube over calls for violence
Bannon called for the beheading of Dr. Fauci: https://boingboing.net/2020/11/05/steve-bannon-calls-for-beh...

Do modern compilers optimize away the memcpy?
tsomctl··on South Park creators have new political satire series with AI-generated deepfakes
Create short deepfakes that can go viral and be so ridiculous that they're both entertaining and obviously fake. Obama advocating for a border wall. Al Gore lobbying for the oil industry. Steve Jobs advising against staring at a screen all day.
tsomctl··on I’m deaf, and this is what happens when I get on a Zoom call
The same. I can hear faint noises just fine, and hear background noise when listening to headphones. I think it's related to my poor verbal skills.
