The iteration cycles are limited necessarily by the time between tapeout and getting chips off the line to a testable state. Maybe there's a little room to get an in-wafer test pro…

I would love a simpler system. Everything is pointing me back towards using a Windows server eval instance for this, which feels like a pretty heavy way to manage a bunch of alpine…

What an amazing tool: it loads and displays the kicad native files in a simple web browser, but moreover - you don't have to be the intermediary, cloning some repo and then uploadi…

How'd that work out for SawStop? A tech that makes table saws basically safe by stopping the blade immediately on contact with water (simplified description). The inventory tried t…

Article is very interesting and focuses on the historic faces of DARPA, not really getting too much into the modern state of the agency. Over the past 10+ years DARPA have embraced…

As a pilot, I love the idea. But as soon as I saw the cockpit I knew the price would be out of my league. I'm still in the single digit gallons per hour world, and this bad boy is …

For me (and I imagine a lot of people) it is his Fallingwater house ( https://fallingwater.org/ ) which is a tremendous example of architecture which builds on its environment. I d…

The other answer about magnetostriction is technically correct (the best kind) but Misses the actual cause, which is subharmonic oscillation. This occurs when you have not stabiliz…

Looks like it uses yahoo_finance_api in rust. In theory that supports options, but no idea whether this tool handles that data properly, I didn't feel like searching that hard. It'…

Website was not pleasant to use on mobile, I couldn't really see much, and the demo was definitely not mobile friendly. At least on a pixel 6. I like the idea. I take it as an all …

Interesting that all but two of the listed startups were software companies (FedEx, Tesla). I imagine the costs of fixed investments required to scale a company not based on softwa…

> try to get by on a two-minute shower once a day This is pretty typical aboard ship for smaller vessels on long voyages. Not so hard as it sounds: get wet, turn off; lather up, ri…

Yes, this bothered me too. It's impressive how much energy is required to just melt water much less bring it to temperature. It's 330 kJ/kg, which is 1250 kJ/gallon: 350 Wh. So it …

I can't deal with dates unless they include day of week. I wrote a very simple script (basically a regex) to add a letter indicating the day. Also fun for changing website themes, …

Around early 2019 I set up a raspberry pi 3 running Raspbian. I made the /var/log partition a ramdisk. Haven't touched it since. It goes down for power outages but probably has bee…

There are a number of conformal coatings that can be used to keep a circuit board dry at fish tank pressures. Parylene is my favorite as it isn't too harsh on the board materials a…

You'd want a quote if you're spending that kind of money: https://www.voxa.co/solutions/mochii/faqs How much does one unit cost? Mochii starts at $48K for the imaging only unit. Th…

In the US so health insurance and PTO, then 401k. Hate unlimited vacation, I like owning my time off. I'm a hardware engineer so remote work isn't very important for me. I don't re…

Yes, it can be that hot; I cuddled nude with a TLAM in the Carribbean to stay cool. I think UK boats were built for colder waters; the ventilation couldn't keep up on the deck in t…

While true, confidential restricted is not a US classification marking. It sounds more like the language on a clickwrap license installer, like what you would get for the radio pro…

A strange document. Clearly written for public release but containing reactions of apparently sensitive clarification markings. Moreover it contains absolutely nothing of well publ…

> I call bullshit on that. There is no "maintenance" on that design, it was already done and paid for. It's a trashcan, it doesn't require specialized tooling to the cost of $50k. …

Depends on your bracket I suppose. According to this [0], an individual $180k salary in AUS is taxed at about $58k. In USD would be about $44k. But... I pay $12k in health insuranc…

Well, if you're asking for opinions, I'll offer a few. I certainly appreciate having another option for focused tech aggregation, especially if the comments section is able to attr…

As an EE I love the idea of open firmware. I wish more companies would provide it - akin to the old TVs and other equipment that came with [full!] schematics inside. It would let m…
