> This of course ignores all the fixed costs, so it doesn't mean much.

Au contraire, my friend. In business finance there are roughly 2 methods to calculate costs per unit: direct costing (DC) and absorption costing (AC) and they both have their benefits/disadvantages.

DC is where you leave out fixed costs to estimate if you will ever reach economics of scale. If a growth in production doesn't lead to diminishing marginal costs under the DC method, then you can never reach profitability under AC.

As long as DC leads to gross margin profits, there's hope of economies of scale and "all" you need to do is to increase production to make it work.

Of course this distinction doesn't apply for accounting and your P&L (however there are ways to get 'creative' with costs and depreciation there as well) so this is purely about decision making: should I build product/factory or not?
You cannot split "hoaxing" and "playing" up like that as "ing" is a suffix denoting tense with "hoax" and "play" being the verb.

A quick Google of "hoax" suggests it's possibly derived from the 17th century noun "hocus".

I could. Regarding programming in general, there are Perl, Python, Ruby, Rust,

after almost 10 years of the release of the iphone, still can't get my head around that people willingly choose that inconvenience in the name of the dictated cool.
I wish this would spread more.

For example currently noone submit community made patches of SimCity 4 to SimCity 4 forums, because the EULA forbid it, and Electronic Arts DID contacted forum owners about it, saying that if they allow SimCity 4 patches in their forums and sites, the EULA will get enforced and they will get sued.

Even discussing making a community patch for SimCity 4 get you banned on those forums...

I am very sure that if EULA were non-enforceable in the entire world, people would start patching SimCity 4 to work properly on new computers in 6 months at most.

Related: While flipping through the slides I was annoyed how many of Perl's plain old names aren't really exact name but more casual description. .say, .hyper, .race, start for Promises in this slides. Even the keywords my, our, has annoy me a little bit. Not to forget strange jargon like bless.

Yes, at the end they all are token and one has to learn them. But I miss more exact words for some value of exact. Going a little bit into the ObjC school of naming would do Perl some good.

Maybe not large scale colonization - but once the Martians start having kids (if possible) and produce them in large numbers, imports from Mars (specialized, high tech manufacturing equipment) will increase. The Martians born there will not care living under harsh circumstances - they won't know any better. They will just keep working to make their lives a bit more comfortable, one generation at a time.
I've been part of other not-for-profit orgs with countercultural missions. It's always been possible to get a few members -- not on the board -- to step forward and do a yearly audit of the books. These audits aren't high-end finance work products: you'd have to pay big bucks to somebody like PWC for that. But they do spot stuff like misuse of payment cards.

It's interesting how members who have finance experience, and members who want to learn something about finance, both step forward. A good volunteer audit can be part of the educational mission of the org.
I agree with most of your comment. I never understood the idea behind prop 13. A naive interpretation seems to be that it lowers taxes on the one item where dead weight loss is very low. This is in addition to the argument that it's a plain handout to the rentier class.

>That, combined with rock bottom interest rates (driving down mortgage requirements)

Do changes in interest rates affect underwriting requirements? I have to admit that I don't know anything about mortgages, but they always looked like volatility products to me.

I do agree that the fall in interest rates has caused property prices to increase. This seems to be related to the fall in return on capital so it's unclear to me how rates might be "jacked up" and why that might be desirable.

Even though GPG has been around for almost 20 years, there are only ~50,000 keys in the “strong set,” and less than 4 million keys have ever been published to the SKS keyserver pool ever. By today’s standards, that’s a shockingly small user base for a month of activity, much less 20 years.

Published keys are not a representative for gpgs userbase, a great amount of 'powerusers' (whatever you want to call those who need encrypted messaging to work) will not publish their keys for numerous reasons, only some of them technical.

Cryptopartys started like this and political activists still do this: you exchange keys in person, you'd never ever publish them on the net, you would not be part of moxie's 'shockingly small user base'.
It's interesting to compare the sophistication of Apple's marketing with the ads made by typical S100 computer companies of the day.

There were a lot of the latter, and some of them survived for a while. They all had ads similar to the original Apple ad - a so-so logo, mostly a list of specs in a small box, perhaps with a photo or line drawing of a board or a monitor, no colour anywhere.

The ones that understood a little about marketing usually had a man in a suit using a computer next to a pot plant.

None of them had anything even remotely close to the slick and polished presentation put out by RMI. That Intel ad is incredible for 1973.

The difference is in the timing. Prior to receiving an NSL, it's legal for you to say you didn't get one.

> you setting up a system that you know will either force you to lie, or to break a court order by communicating something you were ordered not to.

Which is not illegal, and therefore cannot be punished. I wouldn't be surprised if they make warrant canaries illegal (they are already in Australia?) for this reason, and it sorta kinda makes sense, but it also sucks.

Edit: though I guess you could argue that "preparing to break a court order" is some sort of crime, but

1. It's in this case equivalent to making warrant canaries illegal, and

2. Laws that are punished only occasionally are the scariest thing.

There are differences between atomicity and thread synchronization. An atomic write means that the variable is always in a correct state. For example, a non-atomic write could write half of the integer in one instruction and the other half in other instruction, so a thread could see that intermediate, incoherent state (actually, a write of a integer is always atomic in 32/64 bits, but this is just an example).

But that the write is atomic does not mean that it is synchronized with other cores. For example, thread A in core 1 could write the value of x, but later thread B in core 2 could read an outdated from its L1 cache. You should use memory barriers that force cache refreshing, so all the threads always see the same version of the variable and do not rely on possibly outdated cachés.

About the unlocked stdio, I don't think there would be a clear advantage. For best performance, I/O is done in blocks as big as possible, so locking mechanisms should not matter that much (you spend much more time in the actual I/O than in the locking). It should only affect significantly when doing lots of I/O calls, but even in that case, removing the locks would not improve performance as much as grouping and batching those calls.
Yes, ill people are a relatively captive audience.

This is a reason to force price transparency, not hand wave it away. Especially when the institutions in question have been granted exclusive local licenses for some equipment.

It would give people a chance to price shop when care isn't urgent. Lots of people would drive a couple of hours to take advantage of the hundreds of dollars of differences in prices for things like CT scans. This would normalize prices for people seeking urgent care! Of course, that would undermine the entire way we fund care in the US, but whatever.
It's just a marketing thing, what "entry-level luxury" or "luxury" or "exotic" means is defined mostly buy the companies selling the cars, and the media industry talking about those cars.

No. It is a different post, on a different research, by different people (on the same topic).

I consider the earlier result is of much worse quality. (Saw it, but I was hardly impressed.)
> still is a shock to people who believed somewhere in '90 that the next stage in the economy is the shift to services

You should tell the UK's political class. Moving away from manufacturing to services has been been official dogma here since the very late 1970s.

As a result we have an economy founded almost entirely on tax havens, speculation, sporadic renovation projects for rich people, and asset price bubbles, with a bit of marketing and corporate communications around the edges.

Ask HN: Renegotiating Rate with Consulting Firm
A local firm is in dire need of developers, but has a terrible reputation as a sweat shop. I took a position at $X an hour for a consulting agency (W2) working on location at the sweat shop. After being on the job for about a month, I discover that other developers of similar or less experience are making 10-15% more on their hourly rate than I am.

So the question is; what's the etiquette for asking for a raise in these situations? When signing on I did haggle a bit and got a little better than the initial offer, I had no way of knowing how much room there was to negotiate. The rate I'm currently at was a significant raise for me, but I also don't want to leave any money on the table. Has anyone else dealt with this?

The first two are terms from statistics. The last refers to topological compactness.

It's probably not quite so difficult if one actually knows statistics and analysis. Or so I'm guessing.
The problem is that we're mostly releasing CO2 that has been captured by plants millions of years ago and turned to coal/oil/gas. Releasing the same amount of CO2 from freshly grown plants would be neutral.
The magic ingredient was that I had already been doing it for around 20 years. I doubt there's much of a shortcut. Or maybe there is a shortcut and I was never clever enough to find it.

I don't know if this will be helpful at all -- but even after being a professional programmer for nearly three decades, I still read the "basics" chapters of every programming book.

"That China’s propaganda apparatus has a problem with satire has long been evident. In 2012, The People’s Daily fell for a satirical report in The Onion voting North Korea leader Kim Jong-un the sexiest man alive. The Communist Party newspaper ran a 55-page photo spread in tribute to Kim, quoting the Onion as celebrating his devastatingly handsome looks, round face, boyish charm and strong, sturdy frame — not realizing it was satire.
