1. The strength of a currency is its ability to be exchanged, so forcing them onto several (possibly themselves compromised) networks increases transaction costs and changes the economics significantly. Similarly, hardened networks likely impose additional overhead. Finally, smaller networks are easier to perform 51% attacks on. If you can break it in to 10 networks, you only need 1/10th the power to 51% them each in turn.

2. My point was about the strength of the bitcoin network as it stands. And I think you agree that it's both vulnerable and non-trivial to fix, so Im not actually sure what your point is.
The APU provides electrical power but only when there's fuel for it to burn. In the case of the Gimli Glider, it therefore would not have worked.

If we look at the case of Cactus 1549 [1], though, we see Capt. Sullenberger turned on the APU immediately after both engines failed. This has been hailed [1,2] as a good decision -- no doubt because the A320 relies so heavily on electronics for control and it could have helped them restart the failed engines.

Commercial jets certainly do also carry traditional batteries for various uses. Take the Boeing 787 as an example; its onboard batteries originally presented a fire hazard [3].

There is indeed a difference, but I don't think it makes us software developers look very good. Shouldn't we at least aspire to the same level of professionalism and quality that good engineers have achieved?
If there's a big influx in the supply of money bit it only flows into one sector of the economy then the average inflation might be higher, but won't necessarily mean a constant rise in all prices. So I would argue distribution matters also. Likewise, all that new money being spent inside a certain market might raise the average price level if it's supply constrained, but it might also grow the numbers of players in the market leading to higher supply and price competition.

I think business school is already disrupted with startup accelerators like YC. It's a matter of time before they realize it. Some accelerator programs even want a tuition. I've pondered this a lot thinking what I would learn to go to business school, but problem is that you can't get funding to start a company, but you can get funding to attend business school. Hence why business schools exist now. But 10-15 years from now this will change.
He's not making a comparison to the traveling salesman problem; he's saying the businessperson only intended to visit one city, but the trip ended up requiring visits to several additional cities.

It's not a terrible analogy. You request an HTML page and you don't know until after you load it (visit the initial city) exactly what other resources--images, css, js, etc.--you'll need to download (additional cities to visit).

Hello fellow bitcoiner! I am also very aware of MSB regulations.

However, anonymity has never been a priority for the US government.

If you look at the timing of the BSA (October 1970) and the Nixon's war on drugs (June 1971) you begin to see that this isn't about government control for the sake of control. It's about providing tools for a specific agenda. Regrettably, these tools are never dismantled and the government is never held accountable.

Now, if you look at the interests behind the war on drugs, I am reasonably certain you won't find it being funded by worried mothers or fathers.
Oh boy.

> tired of the "Agile"/"Scrum"
> bullshit.

Probably the best way to appreciate Scrum is to have worked on a commercial software product before it. Scrum exists to protect the developer. It explicitly says that estimates are inaccurate by their nature (estimating in story points, never time), estimating is hard and needs the intelligence of the team (planning poker), and the bigger the estimate the less likely it is to be accurate (fibonacci-ish estimate sizing). It allows developers to hide important tech debt removal inside stories by making stories explicitly stated in feature terms, and not in terms of items that a product owner can deprioritize. And it has a focus on making sure there's proper knowledge sharing (anyone works on any ticket, pair programming, dialy standups) so that you don't get a silo'd project where only one developer understands how one piece works.
> how it can turn recursive structures like expressions and statement blocks into linear sequences of instructions

I think this is one of the key concepts in a compiler, yet I don't think it has much to do with parsing.

Parsing (in a compiler) is the act of taking a linear sequence of characters or tokens, and turning them into a rich AST structure.

The back end of the compiler is what takes this recursive structure and flattens it out into a linear sequence of instructions that "mean" the same thing as the tree.

Parsing is critical, of course, for building a working compiler. But I think not focusing on surface syntax gets to the key recursive-to-linear insight you mention more directly!

As the page says, they did not detect the cloud, because it was not clearly visible and onboard instruments dedicated to detecting ashes did not work with that particular dry type of ash.
My reason for using fortran (when I was studying physics) was that when going through the university library looking for a computational physics textbook, I couldn't find one that wasn't in fortran—actually I found one (computational physics, Giordano & Nakanishi) but it wasn't enough to get by. Fortunately I already knew fortran, because all the legacy textbooks+journals were written in the language.

It's nothing to do with the size of the battery it's with the chemistry and yes a batter the size of a house might very well not be able to power a single LED because of its internal resistence.

Lithium batteries are rated for current draw based on their chemistry please do some basic reasearch.

And no if you have 2 identical 18650 they'll have the same density and sustained and peak current draw if not they are not identical.

Cell size, chemistry, internal resistance, breakage and short currents etc are all variables based on the exact make of the battery.

yes, but restrict is limited in that it can only be used to tell two pointed memories could never alias. Finer grain aliasing can be done using unions and structs, but it's not as flexible as Fortran and the possibility of non-aliasing is easily broken just by allowing address to be taken.

I've just realised that I have confused this paper with another paper, which I think was from the racket people and involved what they called "nano-passes". I think I've actually glossed over this paper many times for this reasons.

I'm not interested in writing a scheme compiler (there are several good ones out there already), but this looks like it has a lot of useful techniques I can pilfer.
Why would you ever italicize something to quote it? Italics are for emphasis. Either use real quote marks or the > block quoting convention, which, as pmarreck notes, lots of people do use here.

Controversial Reddit communities
effectively bypassing the whole process of parsing... which IMHO is half the fun of writing a compiler

Fun for compiler writers, perhaps ;) I am a big fan of languages with minimal syntax because complicated grammar affects the user as well. The machine may do the hard work of translating the source code, but the user still has to do some degree of translation of their own in their head while reading it.

I view source code as a kind of interface, and I like simple, clean interfaces.
Economists have looked at this and concluded that the spread of market institutions like private property rights has accelerated poverty reduction, because of the effect it has on capital allocation and incentives.

Drugs are just one aspect. I think tax is the larger issue.

It's really not, it's that most devops engineers don't want to learn or even bother and most windows sysadmins simply don't know how.

Windows automation kinda died when system admins stopped needing to know how to work with JET DB when needing to do one serious ad work.

I don't can't think of a single CI or automation thing that works with Linux that you can't do in Windows if pushed I can probably come with considerably more things which are opposite.

Licensing is the only thing really that makes windows machines a pain to work with unless you are big enough for a sell reporting volume licensing scheme.

I think the use of "god-forsaken clusterfuck" was hyperbole, but frankly, if you're working on software that's necessary to enable the holiday rush, doing whatever you have to do to get it out on time and then redoing the whole thing over the next 4-6 months is probably still the cost-effective solution.

Engineering exists in corporate contexts to serve the purposes of the organization. If you believe that the entire focus of any engineering project should be crafting theoretically-robust software, you're either going to have retire early and pick it up as a personal hobby or go into academia.

An interesting reflection on fasting while trying to work. Curiously, I have had the opposite experience of working while fasting, though it may be very different to fast for one day at a time. Still, I fast between dinner on Sunday and dinner on Monday, which usually amounts to about a 18-19 hour fast. I allow myself all the water I want a a few cups of coffee in the morning.

I'm motivated by a hypothesis of mine that biologically our bodies have spent the last 100,000 not consuming regular high quality, high-calorie meals every day. I am a distance runner, and I've been experimenting with my diet for some time now to see what works best now. My subjective experience so far has been fantastic. I generally feel mentally sharper, and my fast-day runs are usually more focused and satisfying than on days when I eat.
Andrew Tannenbaum's Minix [1] was pretty much made for this purpose. The current version is no longer a "teaching OS", but there is a lot of documentation on earlier versions around, including the original 1987 book [2] that Tannenbaum wrote on operating systems (which comes with the Minix source code).

It's way easier than constantly hustling for new jobs. Don't waste your time on Upwork—you'll make peanuts.
It might be time to up your rate again. You've been doing this ~14 weeks full time to make $25k at 45/hr. That's a lot of experience.

You might lose a couple of jobs upping your rate to $100/hr but you'll need half the work to keep your pay the same.
#1 is not accurate but for different reasons.

A forward slip is absolutely required for a PPL checkride and has been for decades (if you'd like a source, see page 45 of the definitive FAA ACS: https://www.faa.gov/training_testing/testing/acs/media/priva...).

However, transport category aircraft (among other issues) have swept wings, which are far less stable in a slip - so slips are neither taught nor recommended for jets.
It's not that "law enforcement is good" or even "drug laws are good" but "hiring people to commit murder on your behalf is morally wrong."

> Clearly the rightness of evading law enforcement and shooting blackmailers depends on the rightness of the law the enforcers are enforcing. With bad law backing them up...

That's not exactly clear, no. In fact it's less than clear, to me, that hiring a hitman is anywhere near the same moral level as "evading law enforcement."

Okay, that's a reasonable interpretation. However, mine was "quality [of code] is better than quantity" or "quality [of features] is better than quantity".

Like the way Lean defines "waste" (muda), the meaning of "quality" and "quantity" in the world of software are highly context specific (and should usually be tied to customer perception).

This article resonated with me. I don't fancy myself as "highly intelligent" or a "loner", I just generally prefer to be alone and being in crowds for extended periods of time drains my energy.

The thought that this is side effect of my problem solving skills and not needing a community to help with most things is interesting way of thinking about how I interact with society.

I assume others here may feel the same way?
The research paper[1] describes Polaris. Basically, you have to make large, sweeping changes to your html, server side. Instead of your original page + js references, you serve a bunch of javascript that then dynamically recreates your page on the client side in the most performant way that it can:

• The scheduler itself is just inline JavaScript code.

• The Scout dependency graph for the page is represented
as a JavaScript variable inside the scheduler.

• DNS prefetch hints indicate to the browser that the
scheduler will be contacting certain hostnames in
the near future.

• Finally, the stub contains the page’s original
HTML, which is broken into chunks as determined
by Scout’s fine-grained dependency resolution

Yeap. I have a distinct memory of ending a shift at a temporary factory job, only to find my bicycle helmet had been somehow crushed or smashed while it was attached to the bicycle. The cost of replacing a helmet was worth about 3 hours of my labour at the time.

This article is all over the place. The connections and conclusions don't really make much sense.

What does being in a savanna have anything to do with population densities and intelligence? The article doesn't really say. The only pertinent point seems to be about collective problem solving and intelligent people needing less help when it comes to solving problems. Which is kinda a tautology. The article then goes on to conclude that being in dense urban environments and being a loner are correlated with intelligence which seems like a non-sequitur.
Want to make money? You can't because your group does not have money.

So join a different group. Or just trade something of value to an individual from a different group in return for money.

This idea that people are tied to their group, and that group interests exist, is simply nonsense. I have no interest in increasing the wealth, population or influence of my own group, I only have interest in increasing my wealth, the number of my descendents and my influence. And if the best way to do that is to abandon my group and work with another group (or none at all), so be it.
Jerry Weinberg has a useful heuristic along these lines, paraphrased as 'Things are the way they are because they got that way one logical step at a time.'

Reading the comments below, I am guessing that most people simply don't understand the terminology you are using. Ie you have to define what are:

1. Public service
2. Lock in a price
3. What are the prices (vs margins)
4. What's a starting price

I understand your question because I get regular bills from my insurance company that say "Doctor usually charges $1,000 for the procedure you had but we have negotiated price $100, so that's what you owe, as you are still below your deductible."
Intent counts, not just the action itself.
IIRC they put a few other aircrews into the same scenario in simulators, and they all crashed. I think what the crew accomplished here is one of the most impressive and inspiring human feats I've ever heard of; more people should be familiar with the story.

Like, sure, Pearson had glider experience... but he applied that experience flawlessly in an aircraft with a brick-like glide ratio, landing with no slats or flaps, all the while losing control authority as the airspeed dropped and made the RAT less and less effective, with 69 human lives at stake. Holy shit.
