>Don't soak your dried beans! Now even the cool kids agree

Apparently socks and sandals are in fashion this year. Is this a phase the cool kids are going through or is it science?

Including heinz five bean, I think I've had 8-10 different beans in the last year. Which bean is this article so scientifically talking about.
In a pressure cooker, time is under a half hour.

I live at high altitude, so no amount of time just boiling in a pot will ever soften dry black beans.

Math is supposed to be about pursuit of truth, not how congenial you are.
Do you have to benchmark again? Why not just say something like "post evidence, please. You're free to use my benchmark source code"? (I guess it's a variant of the somewhat annoying [citation needed], but sometimes it is apt to post something like that.)
It is now time to begin looking into Rust.

I've read the ":NTH-OF-M-CHILD" section about five times through now and I still don't understand what objects you're trying to select or why. A clearer explanation would be helpful.

"For example, we can style the third element, if and only if it’s one of five children:"
That makes sense, except your example has a red background, not a green one, and for some reason the 9th row has a red tile, which doesn't match your requirement that it be "one of five children". Very confusing.
Like it or not, but math these days is a kind of social activity.
Of course.

Because if Rdio and Spotify don't count against my data cap because of a paid agreement, a new entrant into music is probably not going to get much of my attention.

They'd have to be -so- much better than the existing leaders that I'm willing to pay for a higher cap or sacrifice part of my current cap to use them.

That effectively means that to be taken seriously, a new entrant has to pay the ISPs for exemption from the cap. Further, if the ISPs can choose not to make agreements with companies, they become the gatekeepers of who will be successful. Piss them off, and you lose your agreement.

This is anticompetitive, for sure, but the FTC has no jurisdiction over common carriers. AT&T is currently flogging this argument based on cc status on phone to escape reprisal from the FTC about lying about "unlimited" plan vs. their throttling policy that effectively caps such a plan to 5 GB. The say that because they're a phone CC, the FTC has to be hands-off period on all their business concerns.

I suspect that'll be found to be BS. However, if broadband is Title II, but we add an exemption to allow anti-competitive agreements around caps, there's literally zero remedy. It's specifically not under jurisdiction of the FTC unless Congress changes that particular law.

So, not a huge worry of mine as long as it's a "exempt all music, anyone can apply," but big worry if it's "exempt Spotify only." There are plenty of streaming markets that aren't sufficiently mature to be commodities yet (PPV on-demand movies like VUDU, iTunes, CinemaNow, Flixter; remote gaming like OnLive, Sony; etc.) and even the ones that are shouldn't be immune from shakeups.

What industry? I've never seen anything close to these averages for hard science research.
Passing the bar does not "prove you deserve a career" in law to more or less the same degree that getting a PhD does not "prove you deserve a career" in academics. Plenty of lawyers who pass the bar (these days) ultimately are not successful as lawyers, and the low levels of attorneys at big law firms are a grind designed to weed people out in much the same way that tenure tracks are.

Ditto finance.

That's not to say that either law or finance take AS long as academics do to get to the point where you're secure in your position, but neither get it right out of their degrees.
Why do you have to grade so often? Aren't you responsible for deciding how much work to grade? Are you certain assigning homework is the most effective way to gauge student understanding of concepts?

That's something I'll never buy about teachers. All of the ones I know complain about how much time they spend grading papers. I just want to scream "Stop assigning homework!"

Honestly, maybe what we need is new and creative teaching methods that happen in class rather than just piling on work to the students.

(Don't take this as a slam on you, I'm just curious why teachers always go the "Give them homework" route. Kids end up with hours of homework all the dang time.)

Nailed it with first sentence: it takes 10k users to run an app with 10k users! And that will be, by far, the hardest part.

The technical stuff will be pretty much trivial. Any decently constructed app on any decent framework (Rails, etc) on any decent host (AWS, DO) would be able to handle a 10k user app (probably maxing out at 1% online at same time) without breaking a sweat.

And you will have plenty of time to build out the tech because it will probably take you many months to get to even a few thousand users (depending on what kind of app it is, of course).
"Would your smartest citizens really make such dumb life choices?"

Oh, my, yes. One of the biggest problems with being smart is that it makes one especially prone to listening to and trusting in words, because one is so used to doing so due to the fact that it was the rewarded and reinforced behavior throughout their entire life, which remember, has consisted of little but schooling for such people up to that point. It takes additional training or practice to break out of that. After a lifetime of words about how wonderful this career path is, how suited to it they are, and how it's their natural goal, it cuts down to their personal identity to realize that the words were not true, and that's a hard thing to go through. (I am not being even slightly sarcastic. That can literally drive people to suicidal levels of emotional pain.)

The usual dogma among those with a passing familiarity with digital audio seems to be to the effect of, "Bits are bits - it doesn't matter where they come from."

This, as it turns out, is not entirely correct. Jitter can be a substantial problem in digital transport and does have well-understood effects on overall sound quality, and certain DAC designs are much better at jitter rejection than others.

Here, it's a bit of a stretch, but not entirely outside the realm of possibility for jitter to be affected at varying levels by the storage system in use, though there are a lot of variables here (router, UnitiServe, and Naim NDX) that may not have been adequately isolated.

That being said, I don't deny that there's a substantial amount of 'snake oil' in the audiophile industry, and reviews like this should be considered with some skepticism - but that shouldn't mean we dismiss them outright.

I would, of course, like to see tests indicating these differences, as - if they exist - they will be quantifiable with the right equipment, e.g., an Audio Precision analyzer.
I don't think this is new, just more visible. Exactly this same culture is documented in Kidder's "Soul of a New Machine", and if you read biographies of Oppenheimer, Feynmann etc the same was going on back in the 40s. Academic math is filled with stories of famous crotchedy 'X' launching a withering attack during seminars.

I agree with your latter points; I think social media is making it possible to change this behavior. I.e. I view recent developments positively, not negatively.
I'm reminded of 18th and 19th century astronomers and naturalists, some of whom made very important advances. Of course these were usually wealthy individuals before they came to science.

Perhaps there's room for a 21st century form of patronage instead.
Kidney beans should definitely be soaked prior to cooking. The FDA recommends soaking dry kidney beans for 5 hours then cooking them for half an hour to dissolve the toxin they contain. It takes a surprisingly low number of beans to induce the toxicity, as well.

For what it's worth, while a lot of people complain about the Ruby standard library, when I want to reach for an HTTP library that is properly threadsafe, properly supports encodings (and in general is properly integrated with whatever version of the language the user happens to be using), Net::HTTP is a godsend.

People who complain about the ossification are often talking about the aesthetics of the API (since API tastes change, long-term stdlibs tend to feel outdated), or the level of abstraction (you have to do a lot to use Net::HTTP, at least in the past), and not about the functionality. I'd rather people build nice abstractions on top of Net::HTTP than tell me to use something else because the API is prettier.
>wanted to commit to paying him a salary for the rest of his life.

Sounds like to me like this is the problem. Its a lot to ask for lifetime employment, pension, etc. The tenure system causes this. A more fluid employment system would provide more opportunity as recruitement wouldn't be this overly neurotic thing.

That said, I know people in this exact situation. They bounce from university to university. They eventually ended up somewhere, at least most of them, with a couple scragglers who always came off as hugely unlikeable trust fund kiddies, so I'm not surprise they can't convince anyone to keep them or that they feel motivated to work hard.

The people I mentioned above were mostly U of C grads. Salaries there:

>The average salary for a full-time professor at the U of C during the 2007-08 academic year was $170,800—the fifth highest in the nation

170k 5 years ago is nice scratch. Even in "poor" public schools like the University of Illinois, you're looking at 110-120k for entry level professors. Oh, and usually that's without working any of the summer months.

I'm not sure why there's so much hang-wringing over these jobs, many of which pay a decent wage. Yet there's no hang-wringing over the millions who are just as smart and talented in the private sector who have no tenure protections, no publishing rights, no patent co-ownership rights, no royalty rights, and fear layoffs all the time.
>Which is unfortunate, since HN is nothing like working in tech.

Working with SV firms full of men in the 20s is exactly like this. My colleagues are pretty much brogrammers, or overseas contractors (who are similarly young, callous, arrogant, and emotionally...young).

And looking at other sectors of tech, things look pretty similar. What area of tech do you work in that is nothing like HN in terms of this attitude?

(disclaimer: I actually really appreciate HN as a source of information, and there's an impressive amount of expertise here, but as a social network, it's depressing).

Thank you for the advice and good luck!

In all of the interviews I've been to recently, the interviewers continue to press me if I focus on their company and don't say something about why I want to leave my current employer.

After a particularly bad interview, I did start practicing for these types of questions and I'm getting better, but that's still relative. Part of the problem is that I've been in the toxic workplace so long and I'm so desperate to get out of it, that thoughts of escaping push to the front of my brain while I'm in interviews and I either blurt out something I shouldn't [1] or I just freeze up (think deer in headlights), typically a combination of the two which is even worse.

[1] I don't blurt out anything quite as bad as "my current boss is an ass", rather things like "My boss doesn't believe in bug trackers and I think they're extremely important." So far so good, right? But then there's a pregnant pause and I catch myself blurting out, "At least a client threatened to take away our business if we didn't start keeping bug records, so now we have 3-ring binders and paper forms to record our bugs. But that doesn't do any good when the same bug is reported multiple times in every binder and the boss doesn't actually look at the bug reports or give anyone else access to the code." At which point the looks on the interviewers face tell me I've blown it again. (Very true scenarios about our bug reporting and my idiotic blurting out in an interview.)
I feel for the guy.

At the same time one can argue that if len ( Proof1 ) < len ( Proof2 ), where Proof1 and Proof2 are of the same theorem, then Proof1 imposes less cost, and hence is more valuable, since it will be easier to teach, use. etc.
Interesting how it lists Real-Time programming from uWaterloo. It's likely the toughest class taught at the university, requiring at least 40h of work a week.
When it comes to corrosion, the question is always "corrosive in what?" A couple years ago I looked through the Oak Ridge documents on MSRs, and they appeared to be pretty confident that the alloys they were using were sufficiently durable.
This all comes back to profitable work generation. MUCH of science just isn't profitable, you're usually doing something that simply shows that something ISN'T possible. This, to the economy, was a worthless result. The only value was to stop other's from also spending money on that same worthless result. That's fundamentally why science doesn't pay well.
>This is one reason I've had fun on the tilde club I joined a while back.

Is that still going on?
No doubt the guy's exceptionally brilliant, and perhaps one day a mathematician with enough motivation to do it will spend a very long time trying to understand and decipher what he constructed, but my take on it is that anyone that wants to communicate a message, no matter how brilliant, should also go to the trouble of making it as legible as possible to others.
If you look at the source for that example, he actually has 2 selectors that set an item to red, corresponding to the 3rd item in a group of 5 and the 7th item in a group of 9 (Formatted here for legibility):

span:nth-child(3):nth-last-child(3){
background-color:red !important;
}

span:nth-child(7):nth-last-child(3){
background-color:red !important;
}

That threw me for a bit of a loop too. "Wait, is that second item supposed to be red?" It would be clearer if the example and the demo matched up.
Are there any plans for ARM-support? Last time I looked, it did not seem to be supported.
Can you draw that conclusion from this article?

Dunno about other fields, but atleast if you're doing a PhD in CS/math/stats, the industrial options (tech, finance, data scientist, etc.) are great enough that this article posts too bleak a picture imo of doing a PhD and trying out a career in science.

If one wants to stay in science, then there are many other options than being a prof including but not limited too industrial or government labs, research scientist positions at universities, etc.

Also the majority of assistant professors actually do get tenure and I feel this article is implying that they don't. And salaries are definitely higher than 65K a year. Though again, a CS perspective.
More than 80% of the data scientists I've worked with who were born before 1978 have physics phds and went through that trajectory. Data scientists younger than that have a wider variety of degrees, often computer science and/or applied math. But I don't know if most people count data science as a real scientific field.

I have friends in the bio/medical side (phds, not MDs) who are following that trajectory too.

Certainly a depressing perspective, but as a Stanford PhD student (neuro), my thoughts have always been that pursuing science was a decision to work on the problems that interested me at the _expense_ of not receiving good financial compensation. The particular things I'm interested in studying happen to exist primarily within academia (and non-university academic institutions like Allen Brain and Janelia), because the neuroscience work being done in industry (today) is far more primitive (e.g. EEG). This may change in the near future, and I'll reconsider my options then, but for now, I'm under no delusion that my salary (~30k) is anywhere near what it could be for an EE/CS in industry. That being said, if the amount of bullshit and politics becomes so burdensome that it kills the attractiveness of the science, then I'd leave.

When Rust has been around long enough, and people have started adopting it, then we'll see vulnerability reports in systems developed in Rust too. As I said, there are no silver bullets in security.
I think the downside of no PhD is that you're much more likely to hit a glass ceiling. There are obviously exceptions but you're more likely to be put in charge of a research project in industry if you have a PhD than not.

Clearly an MS or BS level science student can absolutely eventually do the same things as a PhD or postdoc. The latter just have scientific approaches that have usually been subject to repeated and rigorous challenge by their peers, which means they are typically (though by no means always) more rigorous out of the box. In my time in industry I've found that in many cases that kind of critical challenge doesn't happen as much as in academia.

In the end I think people in hiring positions use the PhD letters as a screening tool for how strong a scientist the person is, without necessarily really evaluating the individual.
User engagement models – proven and emerging
Hello the community!

Can anyone suggest or name some of the proven or emerging models for user engagement? Or a good source to study different models for recurring usage and SaaS?

Im sure gamification is one of the key words, but is there a methodology to follow? Is there a systematic way to filter out possible models based on your desired business model or other criterias?

These tests are all horribly flawed and are in effect measuring the same error: edge cadence. When you pack the bits on a drive they are compressed and if you pull them back off and send them directly to your DAC you haven't give the bit edges a chance to expand back to their natural state. Hence the distorting edge cadence. The only way to truly remove this effect is to stage the bits in a ram disk and let them rest. Minimum of two minutes but if you can, five minutes allows full expansion of the soundscape. Then you send the stream from the ram disk on to your DAC and, voila, no edge cadence and prefect sound every time!

Is it difficult to contort your brain into such backwards logic?

First I notice you have no reply to what I said about Iran.

Second, "has been attacked by Israel"? Really? Or perhaps, attacked Israel because they hate Jews so much?

"Have been neighbors at war"? The last war was 41 years ago! That's a long time to hold on to hate.

And yet somehow, the Jews in Israel do not hate the Egyptians. What makes them different? According to you they have a much better reason for it, considering things like the Yom Kippur war.

Your convoluted logic is backwards and wrong.

> That the situation would be different if israel did not have such and incredibly bad relationship with the whole region.

It's bizarre how you try to somehow make their hate, Israel's fault.

Its a nuclear generator factory.

It uses molten salt as the catalyst for nuclear reaction, using thorium as the fuel.

The molten salt allows passive safety measures, significantly reducing the negative effects of a meltdown. It also significantly reduces the size of the reactors housing.

The use of thorium allows for significantly cheaper nuclear fuel, which happens to be very difficult to convert to weapon-grade nuclear fuel. By very difficult, I mean very difficult for a nation state, let alone a small group of bad actors.
