I was on Wellbutrin as part of my treatment for depression. What's interesting is that Wellburtrin is dopamine reuptake inhibitor while Ritalin and Adderall stimulate (or mimic; I can't find a decent reference right now) the production of dopamine.

I'm one of those people who rather meditates and works out regularly than to take any drugs - I don't like to mess with my brain

Something to consider is that your brain is already messed with, so the use of drugs might be needed to un-mess it. But it's kind of a black art. You need to try things and see what works for you.

I had been on assorted antidepressants and stimulants for a number of years and it really helped to a) read up on neuropharmacology and b) have doctors who would listen to my suggestions about what drugs to try and why I wanted to try them. For example, it's handy to know if you respond better to drugs that focus more on dopamine than, say, serotonin.

(The reality is that no mind-altering drug is so cut-and-dry and completely understood, so you end up being a lab rat in your own life experiment.)
Well, the NSA needed something to make up for the reduced cooperation of service providers post-snowden…

(1) I love this.

(2) Having limited legal knowledge, I'm curious what he means with "a lottery ticket to a lawsuit". Is he indicating that patenting something would make a company more likely to get sued? My basic understanding is the opposite, that patents yield protection from lawsuits rather than create exposure to them. Is this flawed?
I guess you would be right if you were paying $100 a year just for the music.

But, in a way, you are right; it isn't free. Just heavily subsidized is probably a better word for it.
"bundle outdated" will do that too.

I am pretty sure I can think of simpler ways to issue a fee-free license to a patent.

how do I read a book like this? do I copy the code and run scheme? do I translate into my favorite lisp variant?

This seems like a pointlessly retaliatory post to me that really doesn't belong on the front page of a "news" site. TL;DR: Dude gets rejected, extremely busy company doesn't respond to follow up emails, news at 11? They've stopped validating crypto challenge solutions, too, because they're so busy. Should I post an upset blog post about that and submit it to HN, too? :/

I've had this happen more times than I care to count (with a wide variety of companies) unfortunately, and it's usually because, surprise, busy company is busy and things fall through the cracks. There are also possible company policies in play (Google, for example, refused to give me more feedback after they passed on me circa 2007-08) and laws that, while they weren't violating them most likely, could come back to bite them if they were to say the wrong thing. Just like when you're fired, it's usually best for a company to keep their mouth shut and let you be upset about the lack of feedback than risk any other issues that could arise.

As much as I don't want to be "that guy" that doesn't seem to care about your feelings, I'm going to say it: get over it and move on. If they're not interested, find someone who is. You'll be much happier there I promise.

(Side note: I work at FireEye/Mandiant; we're probably looking for someone with your skillset, so why not apply there? ;))
Even with all these metrics I still have to write code even for the phone screen and then have a 6-8 round coding interview where I have to algorithms that I will not use in my job. I don't see that going away.

Also I don't see bigger companies adopting these anyway. They will have their own way of hiring and is usually more relaxed. All these hurdles just make an experienced candidate cringe more applying to a startup.
Well yeah, a crime - or should we say contravention - that we are all guilty of at some point in our professional lives.

I think a functional (or CS) perspective is an interesting approach, but I think you can lose some nice results in introductory differential geometry by following just this course. For example, the Gauss-Bonet theorem doesn't appear to be covered, which is an incredibly beautiful result linking the geometry and topology of manifolds.

For a more classical introduction to differential geometry requiring only multivariate calculus and some real analysis/point set topology, Do Carmo's "Differential Geometry of Curves and Surfaces" is a great textbook.

I put together a summary (key definitions/theorems) from an undergraduate course following Do Carmo at [2].

I'm going to be a bit optimistic and say this might not be as bad as it sounds: nearly always large mass actions involve some side-violence, which results in a policeman getting a black eye or something, and is used as an excuse to bring in massive state violence to shut down the action.

A drone, however, is both inaccessible to demonstrators and, even if somehow damaged, doesn't really provide a casus belli for strategic retaliatory violence. Even the surveillance aspects aren't a real change from the status quo: in the States at least, every worker involved in a contentious labor issue has a full dossier on them about their living situation, social media presence, work hours, personal opinions, voter registration, friends and connections, put together independently by both management and unions. Being involved in a strike, of course, would definitely have been recorded.
It's so that everything is better and you know everything about everything all the time and then everything is better because you know all the things and can track it and turn it into data.

I'm getting a little tired of the onslaught of products which attach technology to items/habits/lifestyles that (IMO) are obscured by technology. Does the jawbone bracelet improve my understanding of my own habits and body better than care contemplation and meditation would, or does it add an (incomplete) layer of abstraction to an already complicated system? Do a few meager data points help me better understand what's going on with my body?

With these technologies we must force ourselves to weigh the negative impacts against the perceived values.

What is the environmental impact of creating this item?

How much does this item increase my power consumption?

How is the data collected by this device used, who has access to it?

Is there a problem that this product solves?

What kind of impact does this product have on the people around me?

If this item is just a toy, does its environmental impact justify the purchasing of it?
How long does it take to sell stock when you're an insider? Isn't there some kind of planning/disclosure process that has to occur? If so, I wonder how long this has been in the works, and how long the Board knew about it.
What do you think of Burke's Applied Differential Geometry?
This reminds me of Nokia's attempt to make their mobile platform popular by supporting existing android apps. This backfired and lead to developers not making native apps for their platform because they could just reuse their existing android app and still reach all the users.

Mozilla is taking the opposite approach. Their platform already has reasonable support because it doesn't take too much effort to port an existing web application to their platform. By making apps for their platform compatible with android, they might get developers building for Firefox OS first and then just reusing their Firefox app for android. It sounds like a bit of a stretch, but developers already do this with tech like phonegap. This will attract the same crowd as other html5->native app development platforms do.

The advantage for Mozilla here is that if developers use their devevelopers tools to make apps, their apps will look more in place on Firefox OS and advance the platform.
You shouldn't attempt to put people into groups before you know which groups people would belong to.

Sure, I understand, there are many albums that I enjoy in the entirety and not so much with individual songs.

You can always buy the albums.

As for you question, such a thing already exists; they are called samples.
Tesla Goes Open Source: Elon Musk Releases Patents To 'Good Faith' Use
I don't. This book recommends, say, MAC-then-Encrypt and tries to justify it in 2010 by perpetuating FUD about provable crypto (proofs are only valid if your primitives are ideal, therefore you should worry about--one set of--risks that you can't measure, so trust us instead of proofs). There's no excuse for doing that.

In general, the authors seem to subscribe to "crypto is black magic" school of thought, which doesn't make for good pedagogy.
Exactly my thought, the video seems satirical. Especially when the guy pours beer in the cup and it tells him that it's beer, after which he gives it a "that's right" nod.
Did you really just type this? haha

Well this thing is a cup, spectroscopic device, hydration tracker,and daily caloric planner, that integrates with your smartphone through bluetooth, while charging wirelessly.
Spite, no longer believing in the company, not wanting a large chunk of their wealth tied up in something they no longer have much of a hand in, or just wanting their money so they can buy a bright new FU sports car and blow some cash on whatever their next idea is?
Not literally, of course. I tried Focalin-XR and Concerta, settled with Concerta, as it really smooth.
I love Elon Musk, and kudos to them for doing this, but it's useful to read between the lines:

> Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters.

This is consistent with my view of how engineers in the traditional disciplines view patents.

> At Tesla, however, we felt compelled to create patents out of concern that the big car companies would copy our technology and then use their massive manufacturing, sales and marketing power to overwhelm Tesla

This is the precise thing that patents are designed to prevent: to keep the market from turning into a race to see who can outsource most efficiently to China and inundate the public most completely with advertising.

> The unfortunate reality is the opposite: electric car programs (or programs for any vehicle that doesn’t burn hydrocarbons) at the major manufacturers are small to non-existent, constituting an average of far less than 1% of their total vehicle sales.

So the other manufacturers didn't copy Tesla's technology, either because they are incapable of it or because they didn't feel there was enough money in it relative to their traditional markets.

> We believe that Tesla, other companies making electric cars, and the world would all benefit from a common, rapidly-evolving technology platform.

In other words, it helps Tesla more to have lots of companies developing electric cars to push back on regulatory barriers and consumer perceptions than it does for them to protect themselves against larger manufacturers copying their technology. Also buried in here is the assumption that Tesla is, now, far enough ahead of its potential competitors that it doesn't matter if they copy the technology.

I think this is the right move for Tesla, but there's a lot of dynamics at play that have nothing to do with the usefulness of patents in general.
Would it be though? Amazon spends a lot of time on the traveling salesman problem too, but only the extreme high end architect level people, on a very tiny number of teams.

99.9% of engineers at Amazon are writing, well, downright normal code.

It seems silly to test someone on something they will never, ever run across in the course of their duties, and which you reserve for only a tiny, select portion of your workforce.

It'd be like requiring all the waiters in a restaurant to also be qualified chefs. Yeah, cooking is the core of your business and highly relevant to the organization as a whole - but not to this position.
Here is the takeway:

"Mr. Rowghani has been selling Twitter shares heavily since May, when insiders were first allowed to sell after the company’s initial public offering in November.

Last month, he sold 300,000 shares, worth about $10 million. And this month, he sold nearly 75,000 shares worth more than $2.5 million. He remains a major stockholder, however, owning about two million shares, according to his latest regulatory filing."

This is a non-story. This is a guy that had a mountain of net-worth 'on paper' and since he is now legally able to, he's brought a portion of that net-worth into the bank.

I don't know about you, but if I had 50MM+ on paper in a single investment, I'd want to take at least a fifth of it and turn it into cash for investing elsewhere, building that dream home, going on vacation, etc.

Now, maybe he's filthy rich already, but this just strikes me as a very typical, sane 'diversify your assets' type of situation.
The effective evasion and bots "stupidity" actually come from the lack of cultural context: through school, TV, Internet, etc. humans get a lot of common information that computers don't have yet. For example, even if you never played ice hockey, the question "would you like to go play ice hockey on a beach?" will never produce "count me out" response from a human. Humans will either be surprised ("how can you play ice hockey on a beach?") or frustrated ("do you think I am an idiot and don't know you can't play hockey on the beach?"). Now imagine an even bigger context around movies, songs, sports, ...
I guess when you're absolutely sure that you're right, but the observation proves you wrong, you have to be prepared to consider the possibility that you're wrong.

The comment I was replying to was saying that the file system takes care of it automatically, so there's no purpose to arranging millions of files into directories. I'm not going to speculate how it all works under the hood.
>> "1. I receive daily emails on my main account urging me to advertise. Or more properly I don't see them because I've marked them as spam."

Me too! I used their ad service once and despite telling them not to send anymore emails I get bombarded with marketing emails every single day.
Making Ads Better And Giving You More Control
Newspaper headlines very often omit linking verbs (am, is, are, etc) when they can be inferred from context to make room for more important words.

They probably don't have much use on a web page except to sound like a newspaper headline.

> Musk isn't doing it for money after all.

No, it's for money.

It's the charging stations. There aren't enough of them, and it's the biggest problem they have.

Tesla needs the big manufacturers to build electric cars so they will put charging stations everywhere.
Interesting point. In a way, whatever you're sharing or sending is leaving your system.
youtube-dl also has a --recode-video option that takes ogg or webm.
Good point, I should change the question to why is there an expectation that every song be accessible to Prime members without an extra charge?

I just don't understand the negativity towards this service because it isn't exactly what some people want. I see it as a bonus to a service I already gladly pay for. If it doesn't have every song that I would want, so what? I have access to more stuff then I did before at the same cost.
Bad faith would be GM patenting an obvious extension to a Tesla patent. What I think Musk is trying to do is poison the electric car patent pool with Milk and Honey. It isn't just Tesla patents that matter, but the whole landscape. Patents stifle the spread and pace of good idea distribution.

Fundamentally ddos is a problem and will continue to be one solved best by scale (and tech, but scale is critical) until all networks apply egress filters everywhere they interconnect. This is probably not happening in the foreseeable future unless networks consolidate (and if they do, then each is operating at scale as well).

It is a pretty pessimal situation. I think you might see critical services run over clean pipes networks, rather than the public internet, which also is a return to scale.
I am taking the same steps. I am currently working, but am also looking to stand up a security consulting firm/start-up on the side (I have my employer's permission). Multiple income streams seems to be the only way to mitigate the risk of losing a job in the future. That and building wealth (if Tom Piketty is right).
This should be quite easy to fix, one would think. If the name can't resolve to a model class then it should be very vocal about it (i.e. throw error). I think you should create an issue for it on Github if there's not one already.

Whats going on with Twitter? The stock is significantly down and they seem to be going through re-orgs frequently. Have they become stagnant? Its not going to go away but I don't know what else they can do to increase revenue or increase adoption.
Yeah, Jobs did the same thing. There are plenty of people that feel they want to get that psychological tumor out of their lives after being fired and I think it's understandable even if it's not entirely rational in all cases. I'd probably do the same myself.
This is eye-opening (in one chart):

agree, and trying to act like the internet is unusable by 14% of the population (all because they have a disability and those programmers and designers are ignoring their plight) raises red flags. over 1/10 people? really?

she claimed she doesn't know much about the process. which makes me wonder why write an article critiquing it then. but i can attest, making web pages usable/readable/etc to as many people as possible is always a huge part of the process.
> Tesla will not initiate patent lawsuits against anyone who, in good faith, wants to use our technology.

What does that even mean? How do you make cars in bad faith?
Wait, Bamberg wrote a book on differential forms and didn't tell me when I asked him for self-study references (he recommended Hubbard&Hubbard IIRC)? Crazy. (Context: I took a Hilbert Space class from him and only then realized what I had missed by skipping his vector calculus class for the standard intro to analysis.) Maybe he made the generous assumption that I'd already thoroughly reviewed the available books and had found his wanting?

Oh well. Either way, I'll have to check it out. I never did get far in Flanders (which left too much implicit, making it difficult to read) and H&H didn't seem to emphasize the E&M applications I was looking for (admittedly I only skimmed it). It appears that said applications are the focus of Bamberg's book, so it would likely be a better fit.
As a member of an academic institution, it is very likely his research had to go before the institutional review board that governs how to conduct research in an ethical manner. IRB's are far from perfect, but they are charged with weighing risk vs benefit to society.
YC Hacks – August 2-3
There was a time when the web was content (or data) and it would look how the user wanted it to look, configurable via the user agent's preferences. In fact Firefox still lets me choose fonts (and tell websites that they cannot override the fonts). I use the feature for security as well as readability. I wonder how long it is until they decide to remove the feature because it breaks the web...
Is there a changelog of headline changes?

My original headline didn't have the word "strategy" in it, so, someone must have changed it prior to your change, too!
Looking at software patents, I read (2) as saying that a patent is a lottery ticket, in which winning tickets are the patents someone accidentally infringed, thus opening a way for you to sue them out of their money.
That's my understanding of the term too, but it doesn't seem that subjective. IANAL, but in the absence of an explicit overriding definition, I suspect the court would interpret just like you said it; i.e. it's not up to Tesla.

> There is usually an implicit assumption that all contracts are entered into in good faith unless proven otherwise -- which means I'd almost definitely want to enter into an agreement with Tesla if I were to use their technology.

Doesn't that say the opposite? Assuming the sentence legally binds Tesla in the first place, wouldn't they have to prove you're acting in bad faith in order to sue you? I mean, maybe you want an agreement anyway, but to the extent that the term defaults to true, it means you need less contractual protection.
Same experience here, In fact we ported our enterprise mobile platform on FF OS early 2013 but the company (Geeksphone) who was supposed to provide the developer phones did not even respond to emails, we hope the situation changes this time.
