DmitriRavinoff··on On the Scottish independence referendum and the post-Westphalian settlement
Control of borders doesn't imply "everyone keep out." It just means that the government reserves the right to keep people out.

Kinda like a trademark, actually. One has to "defend" a trademark in order to keep it, which can either take the form of an overeager legal department, or you can just find all the people who are using your trademark and give them explicit permission to do so with the caveat that you may rescind that permission at your discretion (like Hormel did with the word Spam).

DmitriRavinoff··on The unstoppable TI-84 Plus: How an outdated calculator still holds a monopoly
This was one more benefit to using an HP-48G. No proctors ever knew what one looked like, so they mostly just cared if it had a QWERTY keyboard.

Not that I ever used the symbolic manipulation, but the equation library was insanely handy from time to time.

DmitriRavinoff··on How Much Should a Landlord Pay a Tenant to Move Out of an Apartment?
The rent control laws were known to the landlord at the time the lease was signed in most cases; the rent control laws in San Francisco haven't changed materially since 1994.
DmitriRavinoff··on Uber's playbook for sabotaging Lyft
It sounds like you don't understand how Lyft and Uber work. You have no control over which driver you get; the driver app lets all the drivers in your area (and an increasing area over time) know that you want a ride. Whoever clicks "accept" first gets it.

The fact that there are so many cancellations is a direct result of the Uber recruiters using a CRM to avoid pitching to the same driver more than once.

DmitriRavinoff··on I am not planning any nuclear attacks
Unfortunately, the probability that someone is able to understand this logic is lowered considerably once you realize that they're working in a job where they're required to act on such threats. Most people who are capable of such calculations will not find such jobs fulfilling, and those who do will find themselves constantly second-guessed by bosses who don't have that skill. It's a profession that selects against Bayesian reasoning.

Humans are -really- bad at intuitively calculating risk, and I have yet to encounter any sort of formal education in the US that teaches us how to properly calculate it.

DmitriRavinoff··on You don't know ice. Neither do I, apparently
The only problem with that is you can't think of cold as something you can generate. Cold is the absence of heat, and so the only way to make it in a place where there is already heat is to move the heat somewhere else.

If you keep it inside the vessel, then you're faced with containing a zone of steadily increasing heat (and thus steadily decreasing efficiency of your heat pump). If you try to dissipate it outside of the vessel, you run into further engineering problems (the heat conduit has to pass through the hull at some point, which creates a weak spot for pressure and a potential heat leak to the rest of your hull).

DmitriRavinoff··on Ask HN: What to do when you are successful, hate it, and can't seem to change?
Raise prices until the tradeoff is worth it or the demand reaches a tolerable level.
DmitriRavinoff··on A Server Naming Scheme
You...do know that Apollo and Hermes are two entirely different entities, right? Hermes is the counterpart of the Roman Mercury. Apollo has the same names in both pantheons.
DmitriRavinoff··on A Server Naming Scheme
Assuming you're doing split-horizon DNS, those records should be hidden from the outside. And the only way to detect the CNAMES other than brute force scanning of a DNS zone is to do a zone transfer. And you only have zone transfers allowed from other relevant DNS servers, right? And your monitoring software will catch a brute-force scan, right?

Remember that the reverse dns always resolves to something like orange.example.com, which gives away no information at all.

Koan. The word you're looking for is koan.
DmitriRavinoff··on Migrating From AWS to FB
An EC2 rep has told me on more than one occasion that they have no plans to support ipv6 because the demand for it simply isn't there.
DmitriRavinoff··on Rm -rf remains
Yes, but if you can't run the chmod binary...
DmitriRavinoff··on Trolling recruiters who harass our engineers
To clarify: if they receive a reply from me, even if it's a "no thanks go away," they have to take the time to read it just in case it's a "holy crap here's my resume send it to everyone!"
DmitriRavinoff··on Trolling recruiters who harass our engineers
I'm not expecting them to filter me out. I'm just causing them to have to spend a little time on something that won't bear fruit.
DmitriRavinoff··on Trolling recruiters who harass our engineers
They don't have to care. If the current spam methods weren't working for them, they'd stop. But someone's replying to those e-mails, and someone's paying their referral fees.

Why should they bother filtering when we do it for them? They prefer to be ignored unless you're going to sign up for an interview or five. This is one reason why I always reply with a short form letter: "Thanks for reaching out, I'm happy where I am, etc" so they have to take the time to filter me out as someone who isn't interested.
