My grasp of group theory, measure theory, and functional analysis are fairly weak, so maybe I'm not the best person to comment on this, but I think the problem may be that you were overoptimistic when you attempted to read those books. Usually when I read books on subjects I don't understand, I don't understand the book the first time I read it. Reading several different books on the subject helps. This requires a lot of persistence and tolerance for frustration. But that's true when you take a class, too!

As you say, though, you need to solve a lot of questions (which I interpret to mean "do a lot of exercises" or "do a lot of problem sets") to understand something. Reading a textbook without doing exercises is minimally useful, although it can help with the "roadmap"/"relationships" thing. Wikipedia is usually a pretty good roadmap, too, although it varies by field.

But you can also read textbooks and do exercises. This depends on the existence of, and access to, sufficient textbooks and exercises, but Library Genesis has recently extended that kind of access to most of the world. Taking functional analysis as your example, the 1978 edition of Kreyszig is on there, and it averages about two exercises per page, and has answers to the odd-numbered ones in the back. This quantity of exercises seems like it would probably be overkill if you were taking a class in functional analysis and could therefore visit the professor during office hours to clear up your doubts, but it seems like it would be ideal for self-study. And if two exercises per page isn't enough, you can get more exercises out of a different textbook, like Maddox (1970 edition on libgen) and Conway (first and second editions on libgen). You can find textbooks on scholar.google.com by searching for the names of general topics and then looking for "related articles" with thousands of citations, because for some reason people like to cite their textbooks.

Unless you can find a desperate adjunct math faculty member looking to make some extra bucks on the side or something, it's true that comparing your answers to the exercises to those given isn't as good as having a TA actually correct your homework. But it's usually good enough.

(Of course you should only download these books if that wouldn't be a violation of copyright, for example, if their authors granted libgen permission to redistribute them or you live in a country not party to the Berne Convention.)

Progress will be slow. But I think the key thing here is to start with low expectations: expect that you'll manage to read about 15 pages a week and understand half of them. I don't think you have to be a Terence-Tao-level genius.
> You're also implying that Machivellianism works better for individuals and corporations.

my position is exactly the opposite of stating that Machivellianism "works better". in fact the comments i have been responding to, and disagreeing with, were making that case, not me.

(in any case, the opposite of "works better" does not mean "works worse")

those comments assumed the following (il)logical connections: a) critical thinking = non-Machiavellian behavior, b) critical thinkers are supposedly the most effective in "getting things done", c) yet, critical thinkers are supposedly the most likely to be punished and rendered ineffective, d) Machiavellianism is rewarded (aka "works better") in big companies, e) because critical thinkers focus on priorities that are relatively unimportant in large companies, such as "shipping product"

not only are some of these points individually suspect, but taken together they are inconsistent and make no sense at all.

- I'm surprised that no current JS VM does lambda lifting (which is the transformation being done manually here). The analysis is easy, the wins are big for function-heavy code, and the tech is easy and well-known. JSC should try it! ;)

- I was just last week sketching such an optimization, but in a more complicated case, and with types to guide you. Seems very hard to do in JS.
I briefly went all-in on security, cryptocurrency, tor, etc., and had a locked down desktop machine encrypted with LUKS. Then, I moved, and it took me a few weeks to get the computer set back up. In that time, I'd forgotten my passphrase. So, I have a desktop machine containing (at least) a couple hundred bucks worth of cryptocurrencies that I can't open. I still think I remember the passphrase I used, but it doesn't work, so I'm obviously missing a word or a punctuation addition (I used the CorrectHorseBatteryStaple method of making a memorable passphrase in this case).

I've been known to do dumb things, and going down the rabbit hole of cryptocurrencies and how to securely use said currencies was one of them. These days I put everything of importance into Google drive, Dropbox, and/or git (not github...a privately hosted git that I access via ssh and runs on a VM on hardware I own in a data center I trust). If it is sensitive, it is encrypted with a passphrase I've been using for a couple decades, and so it unlikely to be forgotten. A high capability attacker could thwart my protections, I'm sure, but I don't have any reason to believe a high capability attacker has any interest in me.

And, I don't hold much cryptocurrency, and what I do hold is at Coinbase, just sitting there on the off chance Bitcoin really does take over the world and a small amount turns into a big value.
To be clear, it's if you know more or less the right passphrase. This is why your passphrase should be randomly generated. Word based passwords are still fine (for memorability, a la xkcd), but you need real entropy that can't be guessed.

For example, if you choose your daughter's middle name your favorite animal, and the street you grew up on, then you have a small amount of entropy, and you'll be screwed in an offline attack scenario like this. The attacker can narrow it down to combinations of words and numbers related to you, and the brute force becomes feasible. If you use four randomly chosen words from a dictionary of 2000 words, then cracking it is roughly equivalent to cracking 13 random digits.

Side note: cycling through multiple random pass-phrases of this type until you find something memorable has difficult-to-analyze negative effects on the final entropy. Ideally, you should be using the first output it gives you.
I'm interested to know if anyone with a decent amount of experience with this technique can vouch for the linear formula? It would certainly be great if that is an ideal formula. I'm curious to know if a slight curve in the formula would in any case be more optimal / natural?

The reason I ask is because I've implemented similar techniques in projects before, and from experience I ran into a few situations where (for example) text would wrap at undesirable locations (such as titles / headings) during the transition while I would resize the window's width. So if anything it may be interesting to extrapolate this technique so that the derivative of the function is slightly smaller on the small end of the spectrum, and slightly larger on the big end. Or maybe a shape similar to a sigmoid function?

* "Amateur hour. Copied somebody else's bootloader. We really would like to see more systems-level contributions to open-source projects."

* "Overkill. Somebody who can't see how a PDF is appropriate here won't be a culture fit. Does he think I have all day to figure out how to open this thing?"

* "Doesn't know Linux."

If someone who is truly overqualified would disrupt your organization, maybe it needs to be disrupted. After all being overqualified would imply that their judgment is superior to the norm within your organization. If their judgment wasn't good then they aren't qualified much less overqualified.

There is open source software called http://pump.io/ that does most of what you want in a social network. If you are technically inclined, then yes it is easy to set up a server and run this. But even if you are not technically inclined, there is such a large population of people who have these kind of skills nowadays that if you search through your circle of friends, you will find them.

Talk to them, ask them to set up a server for you. Offer to manage it on behalf of your circle of friends, and go for it.

P.S. nobody says you have to have only one server and one circle of friends. You can set up a separate one for your circle of political acquaintances too. This is what the web was created for, not to make a small number of new national networks that dominate everything.
This reminds me of the outrage when Uber kicked Sebastian Thrun off its platform when he worked as an Uber driver offering people rides in his Model S (founder of Google X, inventor of the modern "self-driving" car).

The Plant Encyclopedia: The Global Guide to Cultivated Plants
As a tourist my immediate impression is that the infrastructure is quite old compared to other world cities (why are the subways so hot?) and the touristy areas are a lot dirtier than I would have expected. There are also some NY-isms that I haven't seen in other American cities (terror alert levels, garbage bags piled up on sidewalks, ubiquitous taxies, tourists literally everywhere)

I like how it's basically a microcosm of the entire world, and you can reach all of it without a car, but I'm not sure it's worth the inconveniences plus 3x cost of living.
Good stuff!

The "Login to chat" should link to the login page.
I really dig the login system!

I thought it should be vulnerable to
1. find hash on victim's profile,
2. login using the hash + username

But it seems the hash is never actually submitted to the server, neither through the login form nor later on by cookie. That is good news! The implied hurdle is that you'll need to update the hash on each login.
This is also like the recommendation "hire people smarter than yourself" because if they are smarter than you they are probably also more qualified than you (obviously you can find people smarter than you and train them in your field but how often does that happen?)

Again age discrimination is also something easily thrown out.

And overqualification simply cannot be dismissed as you easily point out, the studies that have been conducted a are both contradictory and in your case completely misleading.

Being "overqualified" by possessing an above average intelligence and being more highly educated than the average employee in a menial position such as retail or sanitation is one thing, being overly qualified in a technical field in a highly competitive market is another.

Taking on a considerably more experience engineer than the average for an entry level job might end up good, but it also might not end up that well, you can see it a lot during the recession people needing work accepting lower paying jobs which they overqualify for and they leave as soon as they find a better place.

so no "> research shows that overqualified workers tend to perform better than other employees, and they don’t quit any sooner." isn't universally true, it can be true for certain circumstances but this isn't even the level of overqualification we are talking about.

It's kind of a shame that so many schools push you to study calculus in order to study CS; digital computers are algebraic machines, not analytical ones, pace Babbage. Combinatorics and graph theory would be far more useful.

"For the most part wether the fbi was operating this server or not the people who visit the server came there out of their own free will in an attempt to acquire child pornography."

That was one of the core questions here - why logins went up 350% under the control of the FBI. Was there any advertising, inducements?

the rounds number 0x2000

Does anyone know if this is the default? If I'm understanding this correctly, it's around 10 ms of key derivation time; on FreeBSD we default to 2 s, which should make cracking disk encryption 200x more expensive.
And? the FBI did not create it, it redistribute it much of it I would assume is pretty darn old, wouldn't surprise me if things that originally were recorded on VHS is still around being sold and traded.

It was accepted to Algebraic Geometry in May, (the Foundation Compositio Mathematica journal, not JAG), so it will probably appear online sometime around December. So far I've received three invitations to visit two different universities as a result of this paper. (search for "Price" on these pages: http://www2.math.binghamton.edu/p/seminars/arit http://www2.math.binghamton.edu/p/seminars/arit/spring2016 , I will also be travelling to a German university in October but unfortunately I have no evidence to show for this currently). I say this as someone who left undergrad after four terms and is mostly self-taught, from such resources as books, online papers, and wikipedia.
That's an unrealistic approach CIs and undercover agents are needed to break apart crime syndicates because otherwise you'll end up arresting the "street level" peddlers and nothing more.

Too bad. Police work isn't supposed to be easy. If it is, that means you're living in a police state.
s/rape/statutory rape/g

In our current environment, this is mostly a pedantic distinction because almost all child porn is produced in an otherwise abusive environment.

Also, the definition of child porn is far broader than what would be required to meet the definition of rape, which requires penetration. [0]

The definition of child porn is also sufficiently broad to include any pornographic image that depicts an identifiable minor in a sexual act, whether or not said minor was actually ingaged in said act, or involved in the production in any way.

The FBI also has a stash of already created child porn. Any harm resulting from the creation of said porn has already been done, and is therefore not a reason to not use it in order to reduce future harm.

[0] Technically, many jurisdictions do not have any form of "statatury rape", but instead use other crimes like sexual abuse.
I have studied a lot of mathematics on my own. I did study physics as an undergrad.

But, I went back and studied Real Analysis, Measure Theory, Combinatorics, Topology, and Stochastic Calculus.

I have found, though, that while I have a decent grasp of the concepts my understanding and ability to solve problems isn't as strong as the math grad students who studied these topics deeply.

I have found the knowledge useful, but I would agree that it would be hard to achieve the same results.

> So it is too simple to state that they should obey exactly the same rules as everyone else.

I don't think so. They should be held to a higher standard than everyone else, or at least an equal one, but not a lesser one.

I'm not particularly concerned that doing so would make it more difficult for them to catch criminals - people who are otherwise innocent until proven guilty in a court of law. It should be difficult (but not impossible) for law enforcement to do its job. That's the sign of a society in which civil liberties still have some meaning.

In this particular case, we have the FBI running a child pornography ring to catch child pornographers. Arrest every member of the FBI who was involved, send them to prison and put them on the sex-offenders' list for the rest of their lives. Treat them the way they would treat everyone else.

Maybe then they'll learn to actually respect the laws they enforce, and the judicial process would wind up being more fair out of the need for self-preservation.

I have already given several plausible examples of when a conference could have grounds enough to rescind a speaker invitation without having the grounds to make public accusations.

It's a generalization, but it's based on my experiences. It's not wholly wrong.

> the comment i am replying to posits that "critical thinkers" are the effective people in an organization who are really the ones who get things done.

Critical thinkers are usually the people who want to get things done. They might be effective, if the organization lets them be effective. Or, they might be entirely ineffective if the organization is pathological.

> at the same time stating that these people who get things done are sidelined, punished and rendered ineffective by the organization.

You're reading a lot into a simple comment.

> at the same time stating that these same people are the ones who are focused on low-priority items in that organization.

You've read too much into my comments.

In a pathological organization, the high priority items are management politics. Those politics are the daily work product of the majority of managers. The way a manager gets recognized or promoted is via playing the political game. actually shipping something is a lower priority.

> i agree with you, taken together, those statements are rather inane.. not only that but also wildly inconsistent, an ironic example of sloppy critical thinking.

Well, no. You didn't understand my comments. So you constructed a straw man version and attacked that. Genius!

> i am stating the obvious (which apparently isnt), that you would expect truly effective critical thinkers to be very good at focusing on the main priority within an organization

Only if you believe that critical thinkers enjoy playing the political games, and that they're good at it. My experience is that the people most focussed on political games are utter shit at engineering, and shipping product.

> anyway, critical thinking and emotionalism (bitterness and resentment about the unfairness of it all) would seem to be mutually opposed.

You can engage in critical thinking, while at the same time being upset that people treat you like shit for engaging in critical thinking. The two are in no way mutually exclusive.
