ISS, Soyuz and soon the crewed Dragon 2 all operate at sea-level air pressure with standard o2 partial pressure. Apollo was the last high oxygen environment.

So they have time to validate the systems are working correctly. A direct launch would leave little margin for error, especially on a test flight. Edit: now I think more it also allows for variations in launch performance. Soyuz does a thre

China has a "no first use" policy with nuclear weapons, so it's entirely possible for a conventional war to be fought. They do have a large range of conventionally-armed missiles though, so I have no idea how the escalation p

I have two old sewing machines, I picked both up at the local refuse transfer station. One is a 1920s Singer. It’s super basic, doesn’t even have a reverse, but it’s bullet proof. It’s cast iron but a portable model, so it’s built in to a c

The costs of employing a team to do the radiation hardening design work, running a non-mainstream fab (I believe these chips were silicon-on-sapphire) and small production runs. There's a lot of overheads amortised on to a very small n

Sending from multiple From addresses is a common use case. I send from at least 4 different email addresses all hosted by fastmail in the same account. Having to create different logins to authenticate each sender would be a huge pain. Plus

Post-consumer paper can be recycled in to some forms of low-density card that doesn't require high quality pulp. Egg cartons come to mind, and as a percentage in some packaging, newsprint and sanitary papers. Post-consumer paper cannot

Fish uses parentheses for command expansion, so backticks aren’t supported and the dollar sign is only for variable substitution.

Having used this framework you absolutely use it to train and create novel classification models. I used it to train financial transaction classification models, it works quite well.

Parallels is the best solution in my experience, but they do use a bunch of dark patterns. They used to sell ‘download insurance’ for example, and really push antivirus if you install windows. I doubt this acquisition will change that, thou

I'm not familiar with MySQL but the features I outlined are Postgres specific.

With a GIN index and a JSONB column you can index the entire json document. It's the same index type as Postgres uses for the full text search, but not super efficient. You can also project out specific subsets of the document to an in

It depends on your goals. If you're planning on just setting up a couple of servers then it's all much the same. However for scaling and maintenance I prefer AWS with a tool like Terraform to manage infrastructure. It forces you t

In my country it's considered rude to interrupt people while they're talking or eating. We wouldn't want someone to come to the table without being asked. Unless you're at a dinner service often water isn't served,

I would love to agree with you, but in this case we're talking about electricity distribution. It's almost impossible to start up a second independent distribution network - the towers alone will cost millions, not to mention the

No, there’s no inherent need for every variable to allow a nothing. There is a need for a nothing value in many cases and languages without an implicit null, such as Haskell, F# and Rust, employ an ‘option’ type. It’s a dedicated type that

That’s an interesting idea. The human eye (and the brain in general) isn’t a clocked system, different parts work at different speeds. You can see this yourself if you have an old fluorescent lamp that works on the mains frequency. You won’

I wish the article analysed the differences between the space programs in more depth. The US space program has had several new rocket and spacecraft designs where the Russians (and Soviets before) have concentrated on progressive refinement

That depends on what you're paying for. If you're using Lightsail or one of the t-series EC2 instances you'll definitely get throttled as you don't get dedicated hardware. All other EC2 instance types give you dedicated

I find this baffling. I live in a country with free healthcare but have used private hospitals here in the past. They give an estimate of costs from every practitioner involved before you agree to the procedure. It's not exact but they

This crash involves a 737 MAX - a very modern fully fly-by-wire aeroplane. I think the 777 was the last Boeing jet with mechanical backup flight controls. The difference you're probably thinking of is the Boeing philosophy of ultimate

I like that argument. I wonder if Apple will.

Since last year Apple have allowed executing user-input code providing the application is designed for teaching programming, https://twitter.com/palmin/status/871980560943636480 has a summary. I can't link to

Depends on the rocket. The Soyuz main stage only uses refined kerosene, liquid oxygen and hydrogen peroxide. The upper stages almost always use some hydrazine compound, but that’s pretty common. Almost all satellites use a storeable propell

They definitely are using real passwords. I’ve seen them use 3 of my passwords I know were in password dumps. Fortunately I haven’t used those passwords for years, but other people will be seeing their current password.

Orchestrator and RAFT did not help them, but mostly it was their configuration. The setup allowed an automatic failover to the west cost data centre, so when the connectivity failed the tools did their job and voted in the west coast. The s

Physical collection is risky, but we can mitigate the risks. I can't speak to the US system, but here in New Zealand every political party is entitled to appoint scrutineers to each polling place. They cannot speak or interact with any

I agree, so for my side project I thought a lot about what scale would look like if anyone else wants to use the janky accounting system that works for me. Anything below 20,000 unique (but not concurrent) users could easily be handled by a
