Even if the student can solve optimization or related rates problems just like the ones in the book and in the lecture — but doesn’t know how to start if the optimization or related rates problem does not match their template — then the student hasn’t really learned calculus. At that point, those “applied” problems are just more mechanical processes. We may say the student has learned about calculus, but when it comes to the uses of the subject that really matter — applying calculus concepts to ambiguous and/or complex problems, choosing the best of equivalent methods or results, creating models to solve novel problems — this student’s calculus knowledge is not of much use.

If this is the standard, then we can also say

Having zero online presence would be a reasonable flag, but if you can't find them on LinkedIn but go on to find them on GitHub, StackExchange, forums relevant to their industry, and/or a personal web site, then I would say that quite exceeds the value of a LinkedIn profile in terms of experience and trust.
Hi have noticed this repeatedly as well. Under the "People you may know" section, I see names of people with whom I've emailed only 1 time, often many years ago. These are people with whom I have no relationship, and the only record of them in my life is a gmail email. This leads me to believe that LinkedIn is somehow accessing this data without my permission.

You're right, but here's the problem: things that are robust to evolutionary change tend to kill everything (e.g. chlorine). There's a tension between finding targets that are specific to an organism, but well conserved, so that the organism can't simply evolve away from the specific threat.

This is really the alpha and the omega of antibiotics and antiviral research: finding the specific lethal target that can't easily be changed. It's damned hard, and it's why most of our antibiotics have been generated by nature, not by rational design.

A Few Things to Consider When Hiring an Agency
It is interesting to hear that some hiring managers consider Linked In a requirement.

The problem, for some of us, is that it's awful awful software. It sends spams to our contacts. It is very difficult and unpleasant to use. It is hard to keep accurate and up to date. We don't like sharing our information with it, because we don't trust Linked In.

That is the reason many of us avoid using Linked In, rather than an objection to social networks in general. (Although some of have that too).

Of course, if it's actually harming our job application prospects, I suppose some of us would reconsider. For most actual programmers, it probably isn't, but who knows.

The more general question here is -- what do we do when there's a social website that has become so popular that it's considered a requirement in at least some communities for hiring, and is one of the best ways to network because everyone is on it -- but is also just a terrible terrible website, in terms of both their UI and their business ethics, and we just dont want to use it. Apparently we've found the answer to how Linked In can get away with being so awful though, they've got the network effect and people have to use it anyway.

At that rate, if you used it to get one day of contracting, you would pay for Linkedin for two and a half years, and it would be much more valuable to you than a decade of tech-blogs.

When Big Data meets a Multitenancy use case (part I)
A post on how to build a big data platform using a multitenancy approach...
Huge amounts of ionophores [1] are used as feed additives. That class of drugs is not used therapeutically in humans. I think other antibiotics are also used quite extensively as feed additives, but I'm less clear on them. If you search on 'vancomycin feed additive', you see discussion about replacing it with other drugs.

There are health benefits to the animals (the drugs prevent 'bloat'), but they also increase the weight gain per pound of feed, which the farmer (rancher? lot manager?) is going to take into account.

I was hired at two of the last three jobs because of timely appropriate contact from inside recruiters on LinkedIn. The third was through an outside recruiter.

Sure, 90%+ of the recruiter contacts on LinkedIn are not interesting to me. I could do a better job of telling recruiters ahead of time not to contact me. I use the contacts as a determination of the overall health of the industry and my visibility in that industry. Both useful things to have.

In short, I like LinkedIn. I work with many ex-LinkedIn folks and I think it has added real value to my professional career.

Note that this is at a different level of abstraction from "I do/don't care if you have linkedin".

Roughly speaking, seldo said "I use <proxy> to attempt to predict performance" and you said "I don't care about <proxy>, I care about performance".
The usage patterns I've noticed from watching people use microwaves:

1. Everyone always uses max power
2. Everyone cooks in increments of 30s
3. No other functionality ever gets used because no one knows what it does/implies

Thus a simplistic microwave design would consist of a '+30s' button and a 'Start/Stop' button. This would probably make microwaves much less complicated internally, and thus cheaper and more reliable.

That said, I don't think either of those is part of the design goals of most appliance manufacturers.

Google has good lawyers, and their terms are both brief and written in plain English with no "fine print". Printed, the AdSense terms are less than two pages long. The part about termination and forfeiting unpaid commissions is two sentences long. There's not much to argue or for a court to "scrutinize".

The fact that a large number of people have had five-figure payments forfeited under this agreement (sufficient to afford and warrant evaluating options like this), yet none of them have invalidated the contract in a courtroom thus far AFAIK, is pretty good evidence that there's nothing so unconscionable present that a court would void the contract.
time to buy an auto-clave
I still use Lijit for their "backup ads" feature. Basically, I monitor the CPMs I'm getting from other networks, then set my floor CPM in Lijit to that number. That way, I get about 30% fill with Lijit - but it's guaranteed to be at a higher CPM than the other network. Chaining them together works really well - you just need to do it asynchronously so that it doesn't impact load times.

> So no, my absence from LinkedIn has nothing to do with me being a bad candidate for a job.

- I agree completely.

>If you assume it does, you miss out on a good hire.

- Again, I agree completely.

On the other hand, any company that vets potential employees by LinkedIn, or any single metric or source, isn't a company that I want to work for. So my lack of presence there helps weed out companies that I don't want to work for anyway.
How does this work in the case of namespace collision? Will we have squatters on the uri schemes?
I am in a similar position to you, in that I only very recently picked up any javascript.

What's worked for me: use whatever meager skills you have to work on a real project that you find interesting. Not something that can hurt people if it goes wrong, but something you care about. Concentrate on the user experience. Eventually, you'll learn better ways to do things as you need to.

I made http://asoftmurmur.com

If you want a laugh, look at the source (the javascript at the bottom of the main index). It's probably the worst JS I've ever seen, but I concentrated on the user experience and I'm pretty happy with how that worked out. I'm now building an Android version and the source is a thousand times more elegant and concise. In the grand scheme of things, I'm sure it's still awful, but that's fine, so long as the user experience is good. Next time the code will be better.

Build something real. When you run into a problem you can't solve by yourself, ask for help. This will naturally create a narrow but ever-expanding scope in the face of a limitless quantity of knowledge. I don't know anything about programming, but that's what's worked for me so far.
> For you, it's great. For your company, it's passable. For the candidates, it's disgusting.

Not the OP and playing a bit of devil's advocate but why do I care what's best for candidates? If I'm able to hire the people I need then I don't really care if there's a group of developers that I'll never find.

That's a choice you make when you take your principled stand.

Audience network – Monetize your app with Facebook ads
Not directly related: I have a linkedin account, and once, I logged in and it recommended a connection which happened to be the guy who lives on my second floor. This guy was the roommate of the person who rents the second floor, I have never called, emailed, or texted this individual. He works in a completely unrelated business to me and we have no linkedin connections in common. No social media or any other sort of connections. I have no electronic connections with the other guy who lives in that apartment. I have a different mailing address. The only thing we have in common is that he sometimes hops on my wifi when his is on the fritz. LinkedIn insists they don't use ip addresses for connections. OK. This is incredibly hard for me to believe.

I feel they pump their numbers with questionable tactics and people mostly use it because of fear. Fear that if they don't use it, their career will suffer. Which plays on a general unease that you could one day end up living in a ditch. So, imo, LinkedIn isn't absurd, it is sinister.

It depends on how coupled your code is. Pure ruby application logic is really fast to test, so there is no reason not to test all of it.

But due to the high degree of coupling of logic to AR model code, callbacks, etc., you end up testing much of Rails along with your own logic, which makes the tests slow.

If your "business logic" is just Rails associations and one or two callbacks, then arguably (and this is what DHH is arguing, I think) it probably doesn't need to be unit tested. Other parts of your app are far more likely to break or behave unexpectedly.

However if you are doing any kind of nontrivial software design, unit tests + TDD can be extremely helpful.
what I've seen of khan academy is pretty cursory as far as the math goes (about enough to get through an introductory course, usually), and that seems intentional. There are definitely a few gaping holes in the curriculum, such as no wronskian in diff eqs. And nobody really learns a mathematical concept until they've been confronted with something significant they couldn't do with it immediately, yet conquered it.

Teaching advanced math, on the other hand, is really hard to do when you're interacting with a person because there are so many pitfalls and if you hit even a single one you can't usually continue until you've tracked it down. Khan Academy has material on all sorts of non-math stuff, like economics and other sciences, and they seem to be gearing the math stuff more towards a younger audience, not an older one, which is probably more important anyways to be honest. smart move, mr.Khan, smart move.
Technical debt isn't drastic enough to get people's attention - in particular management. I prefer to talk about the technical credit card - I find that it gets across the point that the debt needs to be addressed.
If we can officially crown a new era, it's the era of pat catchphrases and clickbait. "The Pacific Century" has a nice ring to it; it's memorable; it's a strong catchphrase. So it makes the cut, no matters its inanity. Even serious journalism, academic research, and industry white papers are coming under intense pressure to adopt the methods of punditry.

I'd say this is less about pageviews and comments, and more about acute awareness of hashtags. "The Pacific Century," "Crowning the Dragon," and other such phrases are conscious attempts to create hashtag-ready hooks for the article.
From the ISBN alone, it's difficult to differentiate between an electronic book (such as one retrieved by Google Books) and a physical one. Would it be helpful to add a switch allowing you to specify whether you want electronic book citations or print book citations?

To your first point:

(a) The existence of sexism in other industries does not in fact take pressure off this industry for correcting sexism, and,

(b) more importantly, you're incorrect; of the "prestige professions" (law, medicine, accounting, engineering), it's only engineering that remains stubbornly imbalanced.

To your second point:

It's easily possible for you to be correct that people need to take responsibility for their own careers while at the same time recognizing persistent biases against women.

We were running a blog that added AdSense around February 2012. We had received one payout. On the second payout, it was the DAY we were supposed to get paid when they said our account had been flagged. Didn't see a cent. Funny to see this article come out that April 2012 was when they stopped paying out.

Not sure why this was down voted because it's true. Only a few big pharma have R&D programs in the antibacterial space. As a reply above states, the current system penalizes new antibiotics by reserving them for only the most severe cases. With the cost of a new antibiotic approval in the hundreds of millions of dollars, companies put their R&D dollars into areas with better returns.

That being said, a few new legislative changes have happened and will happens (GAIN Act approved, DISARM Act being considered) that will change the economics of antibiotic research and have already prompted drug companies to get back into the field.
I'm inclined to agree with you, but various hyperboles in your comment make it harder to do so. Some points you make are made by the author in the introduction, which also reduces my confidence in your criticisms.

p.5, emphasis added:

> This isn’t a typical budget cookbook, nor is it a nutritional guide, it’s a collection of recipes that happen to be inexpensive. Pricy ingredients are wonderful, but so are cheap ones—in fact most of our favorite foods can be had for pennies—the raw ingredients don’t cost much. Your time and skill add the value.

p. 9, emphasis added:

> In order to encourage fruit and vegetable consumption, the recipes do not feature large amounts of meat. Many recipe collections created for the American audience use meat as the central feature of most meals. My recipes celebrate the vegetables rather than the meat.

The $4/day figure is from SNAP, and so only represents food costs anyway -- yes, obviously labor costs matter too, but SNAP isn't very fungible. Few of the recipes really require much in the way of equipment or space. It's safe to assume that the typical American family in poverty has a refrigerator, stove, and microwave [0].

Regarding your analysis of kale salad, I'm unclear why you imply the value of the other half of the loaf of bread, the rest of the cheese, and etc., are lost. The author addresses minimum buying requirements by recommending that people amortize the cost of expensive ingredients. (All of the expensive ingredients in this particular recipe remain unspoiled for months, and in particular the cheese has an exceptionally graceful failure mode.) On a different note, the protein RDA for an adult male (female) is 56g (46g), not 70-80g [1].

You really lost me when you tried to double or triple the cheese. Have you ever tried to eat 4 oz of parm at once? Gross.

To recap, I think it's easy to inflate the "actual cost" of any meal when one fails to amortize costs (of all sorts) and assume unused ingredients are never eaten. I feel that the cookbook represents a meaningful and feasible improvement in the average quality of the American diet in general.

> should not be used as a growth promoter and only used to help sick animals

The issue is that a lot of animals get sick from being crammed together in small areas, unable to move, while living in their own feces and urine. If we regulated animal treatment better and required certain living conditions for animals they wouldn't get sick nearly as often and wouldn't need nearly as many antibiotics.

As it stands, regulating antibiotics to be used only on sick animals wouldn't change much since an incredibly large percentage of livestock are often sick (as a consequence of living conditions).
The situation caused by promises gaining popularity and non-IE browsers refusing to implement setImmediate is really quite ugly. setTimeout's minimum value is defined to be 4ms by the HTML5 spec, so if the browser conforms to that and your app makes heavy use of promises (using setTimeout), now you're waiting multiple screen refreshes for updates – so you don't actually want to use setTimeout. Even though the asynchronous requirement is good for developers using the promise API, it really screwed over implementors.

The setImmediate polyfills attempt a bunch of ugly fallbacks, including (depending on which one you use): yield/generators, MutationObserver, postMessage/MessageChannel, onreadystatechange, and finally setTimeout (the slowest).

IMO the browser vendors should just give in and add setImmediate – if ever there was a need for it, this is it. But maybe they consider ES6 features a good enough substitute, I don't know.
