On the contrary, GINI vs per capita GDP show a negative correlation (really, more of an L shape with the US as an outlier). The US is the only country with a GINI over .4 and a per-capita GDP over $35k. https://www.businessinside

I think it's just the cost. The Spica is about the smallest rocket that could get a human past the Karman line. It's 12m high and weighs 4000kg. To get into orbit, you'd need something around the size of the Mercury/Atla

One of the arguments is that if battery production is limited it's better to spread the batteries out over a larger number of vehicles. For example, the RAV4 Hybrid has a 1.6KWH battery (and NiMH to boot), the RAV4 Prime (plug-in with

The problem is that ITER is funded as a science project, and the researchers want to get as much research as possible. So they are going to spend a lot of time studying plasma before they irradiate the vessel with fusion byproducts and it&#

This is a pretty misleading headline. If you look at the price graph in the article, it shows prices between $5-12/MMBTU between 2015-19, a decline to around $1.50 during the peak of pandemic economic slowdown, and a rise up to $15. So

If you’re on a ship and want to get longitude, you don’t predict local noon. you measure local noon and compare it to a clock that was set to noon at a known longitude (such as Greenwich), and correct the offset using the equation of time.

Yeah, I think the real mistake was when everyone decided to use UTC instead of TAI. I can't actually hold the astronomers to blame for this. More likely it was telephone network engineers or someone at a stock exchange.

Astronomers and navigators. These also were the first people that needed accurate time and first people capable of measuring time accurately, so much of the expertise is in astronomical or naval institutions. This was still very relevant in

It is worth asking during negotiations, especially if company is pre-money and the strike price is under a cent. There is no measurable cost to it for the employer. Oftentimes founders are unaware that this is something they can even offer.

Unfortunately, if the window is larger than 90 days, they become NSOs and the difference between the strike price and the FMV is considered regular income, with withholding required immediately. You then have to pay capital gains when you s

Do the Mattermost mobile apps let you log into multiple teams at the same time yet? That was always the sticking point for my social groups and the reason we went with Slack or Discord. I looked and saw some rather inconclusive JIRA tickets

Updating software is as old as space systems that had software. Even the Voyager probes could receive software updates and were updated many times. Curiosity famously was launched without code to do the landing sequence, it was sent over th

In their system, the actual real-time safety critical code is elsewhere, on a dedicated processor. The python code sends messages to the safety code, which applies limits and sends commands to the car hardware. And other safety systems like

If actual controls engineers are involved, it's probably going to a be a terrifying blob of C autogenerated from Simulink or something like that.

Generally, Github Issues are used as a bug tracker, not a community FAQ. Asking a maintainer to compare and contrast their project with another project or git feature seems a bit demanding.

It’s especially frustrating because the article itself presents the challenges as largely surmountable as long as there is adequate awareness.

This is an old article that compares tires in the 20-25mm range. The bike industry has moved to wider tires and 25 or 28mm tires are now quite common on road bikes, and gravel bikes have much wider tires. I would be the optimum is around 25

Most projects use C because there was zero consideration for anything else. No embedded team sits down at the beginning of the project and says "should we use lisp?". It's just C. Or maybe "C, but use a C++ compiler with

With a $5/gallon tax, you could pay $600/ton for direct air capture of carbon. This is the current price for small test installations. There are claims that this could decrease to as little as $40/ton with scale.

About 10 minutes. 1-2 minutes to refresh a docker container, ~2 minutes to build a mostly C codebase in the docker container, ~5 minutes to build a bunch of python environments and run unit tests in them. 3 or so minutes due to bad design c
