>a more hands-on linear algebra course as a first course

It is ideal (and indeed, not uncommon) to have linear algebra and calc 1 in parallel --- for special honors classes. It wouldn't be realistic to do it for the general freshman class. Do you realize just how many students that includes, in a big state U.? "a REPL like octave or matlab" would be wonderful, amazing, if it weren't about as realistic as the space elevator. Do you know how many endless headaches there are with software-augmented courses, even when it's just software you run in the browser? I applaud your ambitiousness but let's just say I don't want to be in your shoes when you've just told a thousand 18-year-olds to install Matlab!

>the notion that calculus has had more impact on history/society

Linear algebra is hard to even put your hands on, historically. There was no Isaac Newton figure putting the finishing touches on an amazing breakthrough "Fundamental Theorem of Linear Algebra". It is the book-keeping field of mathematics. "All the numerical modeling that has been done using matrices" almost entirely arises by discretizing differential equations so linear algebra doesn't win any points there.
In other words, the prompt to "install" the shortcut will always appear for sites meeting all the criteria. I guess one can always remove the manifest file to stop the prompt from showing in the interim.
The footer is overlapping the header in IE11 because #content flex-basis is somehow being set to 0. I'm not sure if IE is being more pedantic on the flexbox spec or what.

This change in prefix-style.css seems to fix it:

#content {
-webkit-box-flex: 1;
-webkit-flex: 1;
-ms-flex: 1 1 auto;
flex: 1 1 auto;

Good resources for the latest hardware developer kits?
It's a pain trying to find dev kits that I can order today (not kickstarter). Are there any good sources that track it all?

Also - anybody find some cool kits recently they want to discuss? I am waiting on an emotive insight (kickstarter from years ago, consumer eeg) and can't wait for microsoft's holo thing to come out. Been an oculus guy for a while, tried glass, leapmotion is cool

I know I must be missing something amazing. All the biohacking stuff on kickstarter is going to be exciting in 2016.
There is also Kallithea (https://kallithea-scm.org/). Kallithea is a free and libre fork of RhodeCode after they dropped their GPLV3 license for parts of the codebase and added a paid user limit.

Kallithea is being actively developed (a 0.2 release is coming soon) by a free software community under the auspices of the software freedom conservancy. See this blog post from Bradley Kuhn for more details: http://ebb.org/bkuhn/blog/2014/07/15/why-kallithea.html

> Realistically, I think that will be a footnote to the explosion of computers and the Internet.

Well we'll see, human lives do seem like they're not worth much, especially those in the 3rd world, out of sight out of mind like another poster said. I mean you could probably kill a lot more of those people with the world standing idly by as long as you have some kind of justification, they can be invaded, bombed, displaced, held indefinitely and tortured with impunity, but now they are trying really hard to only kill as many of them as they really want to, are they not merciful ...

But what is the end goal here, what do they hope to accomplish, when will the killing end?

I think that the US government is in somewhat of a pickle, the war on terror is now being fought for more than a decade, has cost trillions of dollars and thousands of soldiers lives, and for what? There's no end in sight, no easy way out, heck we may be even worse off than before, we have an Al Qaeda offshoot building a state of their own as we speak. You can't just pull out completely and cut your losses because this might come back to haunt us all. The only thing they seem to be able to come up with right now is to further streamline killing to prolong the status quo as long as possible, and even that doesn't seem to be going well.

How the hell are we going to resolve this?

Or maybe I'm just crazy and this will all just blow over after a couple more years of targeted killings, all those islamists may just give up and go home to live peaceful lives, who knows.
The law, as it's drafted, is daft. Holding companies, anyone?

Drone pilot generates footage, donates it for free to his shell company. Shell company monetizes video. Shell company has never operated an aircraft. Profit.

The law only makes sense for commercial activity directly related to flying, as far as I'm concerned.

> The users do not care if you only employ 25% of the drivers, since that's still enough to provide good service

I question that assumption. Once one service reaches a tipping point it may be able to deliver a standard of service that will be very hard for upstarts to match. As an illustration, if Uber wins we may come to expect rides within 1-2 min anywhere in the city and to commonly match riders on Uberpool. Maybe 25% gets you there but at that scale 25% could mean hundreds of active drivers which is very expensive to muster with driver incentives. Also it will be easy for Uber to run promotions to starve competitors of their sole benefit, lower prices, until they run out of capital. That threat will discourage investors.

This is why they are fighting so hard right now. It's winner take all.

At first I thought you were just being obtuse, but you are correct!

USCIS will count the day that an applicant departs from the ​United States​ and the day he or she returns as days of physical presence within the ​United States​ for naturalization purposes.​[1]

As long as the other country counts it the same way, you could spend 6 months in two countries and end up fulfilling the physical presence requirements in both.

By this definition every bootstrapper is 'self dealing'. VCs get to decide how, when and where they allocate their funds, if they decide to bankroll one of their own partners in a new venture then that's totally ok as long as the partners and LPs are in agreement (it's their money after all) and you can bet that they'll have extra outsiders scrutinize the deal to avoid being accused of nepotism in case the company eventually goes south.

VCs with partners capable of executing on their own ideas are pretty rare, but when it does happen it is usually because someone had a side project (possibly even before joining the VC) that got legs (either unexpectedly or belatedly) and this person then uses his excellent VC contacts to secure a deal. And of course he/she does not go to a competing VC, that would be a harder pitch and it would be strange not to offer your partners a shot at the deal first.

All in all I can't see much wrong with this and if you think that it is 'unfair' you have to remember that VCs are not under any obligation to invest in outsiders at all (private funds exist).

Pointless thought-terminating cliches brought in hard and fast, was invoking that "law" really necessary?
You could certainly do that with 2 ports, or 4, but you're being forced to do it now. I'm not okay with that. Just a simple scenario where you're charging and want to connect your 6th gen iPod to the computer needing an adapter is mildly annoying. 2 would be preferable. Apple should really host a survey on their site regarding this.

Let me offer some (hopefully constructive) counterpoints:

> If the system doesn't work for you, it doesn't mean you're not capable.

Sure, but working with the system is a useful capability. Don't be lazy and dismiss it as worthless just because you can't (or don't want to) figure it out. I've made this mistake and regretted it.

> Follow your passions, not external dictates.

Following your passions is great, but doesn't always work out. Life is often about finding a balance between something you really like doing and something that society values enough to pay you for doing it.

> Try to get as many different perspectives on life as you can.

Yes, of course, but the challenge is weighing these perspectives appropriately. Everybody's perspective is right from some particular viewpoint, the trouble is figuring out what that viewpoint is, whether it applies to you.

> Coding is making credentialing and "proving" you can do something much easier.

Completely agree.

> As for luck, I have a bad habit of framing things as lucky, and to some extent they are, but there was also hard work behind them.

Sure, you always need some hard work and talent to succeed but it's often not sufficient, and luck is sometimes the necessary component that makes the difference.

ed: One last meta point that occurred to me was that you became successful when you took charge of your career. When you were just doing what others told you, you seemed both unhappy and underperforming. The lesson I would take is that we all need to take responsibility for our happiness and success. Sometimes this means introspecting and figuring out what we ought to be doing and not just drifting around listening to what we're told by society, our peers or parents.
"I'll sound like a broken record for saying this, but unless you are under contract you can leave at any time. Two weeks is a courtesy YOU extend and nothing more. If you were to be laid off or fired you wouldn't get two weeks notice, would you? You'd be out within the hour"

This is very true. That said, as a professional you need to act like one - even when your employers doesn't appreciate it. For example, the quality of a professionals [think doctor, fireman, teacher] work product isn't dictated by how much they are paid.
You make an important distinction. Perhaps I should have said, "The FCC missed an opportunity to regulate a natural monopoly."

Because you're right in that last-mile Internet delivery is a natural monopoly. Just like last-mile phone service is a natural monopoly.
VCs are under no obligation to invest in outsiders at all.

Yes, it's an old boys network, old boys networks are not illegal nor are they bad. In fact they give the younger boys a fantastic opportunity to side-step the whole thing and start their own network, that's exactly what YC has done.

Whenever you see something like this there is an opportunity.
So where are all the people who in the last thread[0] were so very concerned that the FCC was "hiding" the rules? Are you satisfied?

As long as the money is private, they should be able to do whatever they want. If they're actually bad decisions (a worse startup getting money solely due to being inside), then they'll suffer for it. If the decision however gives a return, then what's the problem?

I don't feel suspicious of family's investing in their kid's venture -- wow how unfair! so biased, they should have given the kid next door a fair listening to as well!

The problem only arrises if bad decisions are then publicly de-risked (as is the case in banks, etc -- don't know specifically if this happens in an indirect way with VC's). But in and of itself -- "people you know" is one of many possibly good or bad metrics you can use to invest your own money (or the money interested to you by funders that know how you operate).

I was referencing this exact paragraph:

> Imagine an employee who takes this policy and chooses to live like a European with umpteen weeks off every year. What to do about that? Simply tie it back to performance and things become clear.

It's probably just my bad English that I don't get the nuance, but it sounds a little condescending.

Are the Europeans actually taking more time off due to being used to it? Is their performance judged more because of this, if they do? I can't really imagine anyone answering YES to that, but it just struck me as odd to include this.

That said, your model sounds very good (compared to what seems to be the American standard) :)
> The goal is to get a return on investment...

This is a simplistic, overly idealistic understanding of venture capital that is unfortunately constantly repeated but rarely rebutted.

The goal in venture capital is to be able to continue to raise funds. On a $500 million fund, a venture firm locks in $100 million in management fees over the life of the fund (assuming the standard 2% annual management fee and 10 year fund life) regardless of performance. Not a bad deal.

But it gets better. Because of the nature of venture investments, it's all but impossible to declare a fund a winner or a loser a few years into a fund. But a firm won't wait 10 years to raise its next fund. It's going to raise its next fund not more than a few years in, and in a hot market like this one, that fund is likely to be bigger, so the firm gets to lock in another 10 years of management fees on an even bigger pile of money.

Carried interest (your "return on investment") is icing on the cake for venture capitalists. Because most LPs are muppets who will continue buying the same inferior product, the real imperative for a venture firm is to make sure its funds are not total dogs. Given historical venture capital returns, that basically equates to not blowing up your fund.

Ask HN: What is your advice for a DevOps newbie?
I'm joining a bootstrapped startup (online service) that just applied for (and received) Series A funding. As we're growing pretty fast (around 10 million users currently), we need to bring down the infrastructure costs and ensure continuous delivery & uptime.

I'm graduating in may and currently playing with various tools including Puppet, Chef, Ansible and Salt. I'm more in favor of Ansible right now.

So, what tips/advise would you have for me? :)
And I guarantee that a) the drone operator doesn't have a CPL, and b) that the FAA hasn't said a word to the show producers.
> Is there such an amount?

Yes. When the income exceeds your expenses it becomes commercial. That's seems like a very clear and bright line to separate the two without worrying about youtube ads.
Yik Yak is going to have to fundamentally change to have a future.

It is the most useless app I've downloaded on my phone. Every time I've ever tried to use it I felt like I had completely wasted my time.

There are a lot of users but each new user doesn't bring that much to the experience. In fact, beyond a certain number they just increase the likelyhood that something negative is going to further pollute the community space.

So, not only is it worse that useless, its main metric is actually functioning backward compared to any other social media app.

There are a lot of smart people throwing a lot of money at this thing. I'd love for one of them to explain the reason because I just don't see it.

Edit: I thought of the perfect metaphor just now talking with my friend who'd never heard of Yik Yak and trying to describe it: It is like reading your local bathroom stall. A half a billion dollars worth of stall walls.
The obvious answer is fair market value, but now you have me wondering if you're supposed to pay for taxes on someone giving you a ride, even in a way where paying for that ride would be illegal...
Thanks mlinksva!
Well the FAA wants the drone pilot to have a commercial pilot license in order to shoot commercial video with it. Seems entirely silly to me. In my opinion there should be an altitude requirement involved here. Like, okay if you own a drone that is capable of going over 2000 ft you need a license to fly it regardless of whether you'll be filming. I have no idea if that is a reasonable threshold or not.
Depending on the fund it does. This diagram explains it:

I get it, we all hate Google on HN (for reasons unclear to me) but this is ridiculous. If these projects are truly important than donate some time and move them over yourself.

We have over a year. There will be backups of all of google code made, and even then the Internet Archive will certainly have a backup of all the software projects on it.

They could atleast work together with the internet archive to conserve it, but no of course not that would require be a bit of an effort, google can't do that, because google doesn't care if thousands of open source projects are going to be lost forever to the world. Don't be evil my ass. Archive team is now our last hope as usual.

What if I don't find a job?
When you learn that most of the guys you graduated with haven't found a job, you start to think that maybe you weren't the problem, but the system is. (Schools say "there are plenty of job ads out there!", employers say "But you weren't taught anything useful at school!"). I'm actually one of the luckiest of the bunch because I do have a few opportunities and I'm confident I can turn one of them into a position - I'll know more about that at the end of the month. Until then, my anarchist/rebel/artist side can't help but wonder: what if I couldn't find a job in the IT field? Life is extremely pricey here and unemployment services aren't going to give me anything. On the other hand, I don't feel it's my mom who should financially suffer from this. I'm 25 and I see a lot of people of my age still at their parents'. In my case, though, my mom deserves some rest. Given that one of my websites brings from $400 to $600 a month (and has for a few years) and that I have a few thousands in my bank account, I'm wondering if I shouldn't move to a peripheral area of a more affordable country (I'm thinking Portugal) and live very simply over there, as I know broke students have done in Berlin or Austin? I don't need more than a computer and books to entertain myself. I wouldn't know where to start except for airbnb.com, though. Does anybody have any advice to give me, a story or useful links to share? Thanks. PS: this is just my mind wandering and I'm probably never going to do this, but still, I'm interested.
When people say there are no native apps on Chrome OS, they are actually wrong. The native apps are just written in Javascript and HTML, Native Client, or in the near future, the Android Runtime. All these types of apps are already in the Chrome Web Store and run offline. So just like iOS or Android where you have to write your apps in a certain manner to have a native app, you have to do the same on Chrome OS.
I think it's perfectly realistic, and wouldn't necessarily mean things would go south post take over. YouTube is still very much alive, brand and all, and it's been many years since the take over.

> "No. And if you come after me, I will just turn you in to the feds."

Ok so you're going to turn the other guy in to the feds for what exactly? How do you know this other guy? Why would him turning you in to the feds be a problem, unless you're doing something illegal?

DPR: He this guy is doing something bad, arrest him!

Feds: How do you know he's doing something bad?

DPR: Well I run the Silk Road and he told me that if we didn't do something about this other guy, that HE was going to turn us in to you!

Feds: Oh, okay well now you're definitely going to jail.

So your clever arrangement whereby you're going to use the feds to get the guy threatening you to go to jail has now fallen flat on its face, because now you're both going to jail. Which is the thing that you were both trying to avoid in the first place.

Why is the drug trade so violent? Because it exists outside the law and thus there's no one to arbitrate disputes (legally) and so people have to find their own resolution. Hence killing.
