For a long time in the US (maybe still?), the vast majority of the schedule was set by the local station. Being a member of one of the national networks brought access to a catalog of shows, and a few requirements about the scheduling of s

The same thing applies to lots of fields of computation. In fluid dynamics, for instance, a direct simulation of the Navier-stokes equations is quite straightforward and will produce the most accurate solution. All the complicated parts a

It can be, but git neither validates nor stores it. All of that is done by optional access control layers on the computer where the git repository resides.

That makes sense. So, continuing with the git/source control analogy, what’s missing is a distributed mechanism of both publishing new forks and then deciding which of those forks “wins”. It sort of happens now in an ad-hoc way, if yo

In a sense, git is “blockchain technology” that predates the buzzword: every commit is cryptographically hashed, including the hash(es) of its parent(s). This lets anyone verify all the involved commits back to the beginning of the chain,

The goal is to run a server that my friends and I can connect to over the internet without the server box getting owned by various malicious actors on the internet. I expect to write the entirety of the server and client networking code my

The cost of recommending masks is that a large minority of people will decide they need the best mask to protect themselves, and buy them up thus depriving the healthcare workers of them. Yes, in an ideal world, the entire situation woul

My aim these days is usually around 70 chars, plus whatever the block indentation is. That way, I can always move the editor viewport to the right to keep the local region on the screen.

This sort of thing is usually measured in percentage lost from the previous peak, or some other relative measure that corrects for the overall growth over time.

Sorry, I can’t resist being pedantic on a post about pedantry. The symbol you used translates loosely as “there exists an x”; I’m pretty sure you meant the upside-down A (“for all/every x”)

Digital typewriters with editing capabilities were widely available from the 1970’s. While I certainly appreciate this as a hobby project, the idea that digital typewriters are new or novel is misinformed. https://en.m.wikipedia

The same way you turn anything into a business: figure out who will pay how much money for what. Then, figure out how much it will cost you to provide that to them and tell your future customers that you exist. If the former is more than

Your reasoning looks right if your employees actually are at 100% utilization. If they’re not, however, the marginal cost to the shop of labor is 0. (1) Thus, it’s better to prefer the option that lets you charge more labor hours when you

It’s a matter of parts vs labor cost. For the shop, the labor cost is already sunk: they’re paying their mechanics to be present whether or not they’re actively working on a job. The replacement bumper is an expensive part that requires l

Audiobooks could be another resource, but they’ll only give you a narrator’s intonation. On the other hand, at some point it may become easier to train people to speak in a certain way to computers instead of training computers to understa

The question isn’t whether the aftermarket cushions perform at the same level as OEM, it’s whether they have sufficient performance for ‘outoftheabyss’s needs. If they’re good enough, why pay more?

This is essentially how we broke apart long streams into manageable archive files at Justin.tv. You can get slightly better decoder behavior if you’re careful about where you make the cut: some frames are encoded as a difference from the p

That looks about right; I’m usually outputting formats that don’t care about blank lines and so skip the “dnl”s and put the start and end quotes on their own lines for readability.

Not right now, unfortunately; my computer is at the office and I don’t use m4 enough to give an example from memory. I’ll try to remember next time I go in.

The pattern I’ve fallen into with m4 is to have a preamble that sets up whatever definitions I’m going to need, redefine the quotes “backwards”, and then place a copy of the new close quote on its own line to start the main body of the file

As far as I know, pain is fundamentally a mental phenomenon: the only way to know if someone is in pain is to ask them or observe a voluntary change in their behavior. Until this changes, the only evidence we can have that a proposed treat

The cited post[1] recommends an enum for this job, which avoids the dynamic dispatch and makes it easier to get at a specific state’s data when you have the whole machine. [1] https://hoverbear.org/blog/rust-state-machi
