I think math can be taught just fine without dragging programming into it. Basic math is usually abstracted away in programming anyway - it would be no different than using a calculator.

Plus, the level that you'd need to reach for the kid to see something interesting as a result of math would require so much time and knowledge that you'd have been better off to just teach them fractions.
Better, but still not quite there IMO.

The Facebook example involves third parties in the form of the people who get to see your previously private info. It's not just between you and Facebook.

Likewise, the RIAA example involves a third party in the form of YouTube.

Finally, the MS/EA/Sony example involves a third party in the form of the courts.

Ironically, I think your last two examples are a near-perfect fit for the people trying to argue about coffee shop squatters. They're taking what should be a private interaction between two private entities and attempting to butt in to control that interaction in a way that suits them, much like the hypothetical RIAA is trying to control your interaction with YouTube, or the hypothetical MS/EA/Sony is trying to control your interaction with the courts.
And I can confirm that if I load 6 tabs in Firefox and go to work, when I come home it will have eaten 2G of my memory, the next morning it will have eaten 5, and a couple of days later nothing on my system will run without disk thrashing because Firefox is sitting at 96% memory usage.
LinAlg 2 coming up in two days. Its a fun course!
Try this again, but instead of:

fake_random = 5

Try:

fake_random = secret ^ real_random ^ 5

No matter what secret or real_random are, result is now 5. You can't hide secret or real_random from the processor.

In a larger sense, there's no way to stop the processor from simply setting result to whatever it wants before returning it to the place where it's used.

My point is, there's no real way to trust hardware that can't be verified.

I've "pre-exercised" before, with a meaning different from what's depicted here in the article.

In the "pre-exercise", I was able to exercise the stock before I'd vested in it, with the understanding, of course, that the company would buy back my unvested shares at the exercise price if I left the company before vesting all the options.

The disadvantage, of course, is that you pay for your stock up front, and will lose all or most of the money if the company doesn't pan out.

There are several advantages ...

Advantage: the price you exercise at is near the fair-market value of the Common Shares you purchase (and haven't yet vested in), so there's no immediate gain and so no immediate short-term gain tax consequences. You need to make sure to file an 83(b) form so you're telling the IRS you're paying your $0 tax up front, rather than monthly as your stock vests. (The disadvantage with the latter is that the difference between what you paid and what your stock is worth as it vests could be huge, and there's no way to liquidate your stock to pay that tax.) (There's also something about AMT in here, I'm kind of fuzzy, but I think consequences can be the same.)

Advantage: your long-term capital gains clock starts ticking the day you buy the stock, even though you bought before any of it vested. When, three years down the road, you can liquidate your stock in that acquisition or IPO or secondary-market sale, you already purchased your stock three years ago, and pay only long-term gains. Otherwise, you'd buy the stock and sell on the same day, with the gains considered as short-term-gains/income rather than long-term gains.

My personal outcome with pre-exercised stock: worked out OK twice, lost all my pre-exercise once, but overall I came out ahead on taxes even with the loss. YMMV.

What the article says is "pre-exercise" is just an "exercise" -- you vested the stock, you have every right to purchase it even though the company's stock isn't yet liquid. The problem, of course, is that you may have a huge gain and no way to pay for taxes on that gain.

(Edit: note about AMT, clarification.)
The sad thing is, this is unnecessary. Why be a despot, when you can be a "democratically elected leader"? The masses will love you, so long as you don't explicitly say that you are a dictator, no matter how violent and bloodthirsty you are.

At least that is what is happening today...
But I don't think this is a workable task in a political system. The views of the guy you voted for are going to be different from the one you didn't vote for. In a perfect system every person will be impartial in evaluating elected officials. In the real world, if you evaluate the guy you DID NOT elect you would be perceived as being biased. On the other hand, if you evaluate the person you DID elect you would be perceived as being biased as well. Both cases you would be perceived as being biased. So the only workable approach is to focus less on individuals and more on the system and its results.
Thank you. My first reaction was: start by firing the first 3 employees who couldn't be arsed to encrypt passwords, and replace them with people you can trust.

Being aware of the current best practices in password encryption is part of your job. Checking if your knowledge is still up to date takes 30 minutes, tops. Implementing it in your stack of choice, provided you've made a sane choice to start with, is trivial. Hell, you can probably just cut and paste from one of the articles you've found in the aforementioned 30 minutes.

None of this will slow you down when getting the first alpha release out of the door.

It would be grand indeed. It would even be more grand if a small project like this would be able to partake in that party's service without paying thousands of dollars for audits, registration fees, insurance fees and such.

But perhaps it would be more grand if that expensive and bureaucratic third party could just be avoided with a smart technical solution :)
I'm pretty sure most of us learnt to program outside of school, and off our own backs. Isn't that the best way?

School is there to show kids how to teach themselves anything they want to learn. Not to spoonfeed them specific skills they may or may not want to have.
Poor treatment of prisoners of war is not equivalent to imprisonment of political dissenters.

Many people at Guantanamo Bay were not captured on any battlefield. Unless of course you define the whole world as a battlefield (as the White House does). That has the unfortunate consequence of transforming citizens into terrorists suspects too and suspending their rights.
How the Year 2013 Changed SEO Forever
There is some very meaningful work to be done in this "perspective/reminder" space

This falls under the category of "knowing thyself". Each man must learn his own rhythms and behaviors well enough to build a system custom-tailored to his needs - and adapt it as he changes, too.

Even in something as simple as the Lord's prayer ("Give us today our daily bread..."), we are taught that, yes, this sort of perspective shift is required daily. And to skip it means that one will begin to drift. I heard a great phrase once, and it's that "vision leaks."

Whether in your own life or leading an organization, if you are not daily renewing the "stickiness" of your vision, it will leak.

I like to keep an ever-changing whiteboard (otherwise my brain soon ignores it) of short reminders on the wall next to my front door, and also a plain notebook that I carry everywhere for weekly to-do / prayer / big-picture reminders. Journaling helps too, but I don't do that daily.

The thing that ties it all together though is the daily restoration via a relationship with Christ, I am always learning something new in prayer and through reading the Bible. Many on HN would deny and balk at the existence of a man's soul/spirit, but what you're talking about missing has been known for thousands of years as daily spiritual renewal.

If you think the answer is a daily ritual like meditation, you'll simply grow tired of that habit quite soon. And rightfully so, it entirely misses the point of what God intended - a grace-filled and dynamic daily relationship with Him.

I was not specific enough. I should have said if someone takes part in a protest against all meat products. You are right: it is not hypocritical to campaign against inhumane treatment of animals but not against humane butchering.
> Anything other than a perfect grid in neighborhood design is due to classism?

Wow, talk about putting words in his mouth. He's referring to the status quo for American suburbs where those meandering side streets don't connect the arterials except at just a few choke points and there is no walking connectivity either. Fix those things does not imply "perfect grid".
I'd appreciate that. My linear algebra is extremely basic (all picked up as needed for an AI course). Any well-rounded ground up resources would be awesome.

Meet Jack. Or what the government could do with all these planes

>Article showing how half of San Francisco gets bombed

This argument can only hold on water by having a complete lack of faith in the rule of law.

The biggest issue I have with this is that this describes a massive , coordinated system to use all this location data in ways that are way outside the legal framework in place by the initial court order from the FISA court.

Stuff that has come out of these leaks have ranged from banal (oh, we listen to the German Chancelor's cell phone? What else is new) to absolutely damning (forcing companies to hand over SSL keys). But even in the most damning cases, all of these happened within the legal frameworks given to them (such as the National Security Letters) and maybe some overzealous law enforcement agents. The illegal incidents can be explained more by incidents outside of how things are "supposed" to work (LOVEINT is probably not sanctioned by the NSA), and a lack of strong implementation of the framework given by the courts.

The narrative has always seemed to be "check out how the NSA is going crazy over here!". But the reality is "check out how all these politicians are voting in these new laws allowing this to take place!"

From the leaks you can even see how the courts are constantly reeling things in, the system is actually working. We hear about old NSA programs that got shut down because of the FISA court's rulings. This is how rule of law works! We vote laws, and people follow them.

To actually come to this, given all we've seen from how courts rule on this issue in general, and the FISA court's rulings, this sort of data sharing would absolutely definitely not be allowed to exist. No judge would agree to this being allowed to be set in place, as it so obviously goes against 4th ammendement in such a program's intent.

Just because the data is at the NSA doesn't mean they can use it however they want, just like how Google would run into some problems if it tried to sell the contents of your e-mails to somebody.

This anger at the NSA should also be directed at the congressmen voting for these laws of large scope in the first place. Hopefully we can get rid of NSLs too. But the NSA is just doing the most it can with the tools we give it (which is what we expect). And rule of law is actually working, we just have some shitty laws.

"The only place I've ever even seen this claim is on vegan advocacy forums as unsubstantiated claims or in studies of nutrition absorption problems as a general factor in the elderly."

I'm looking for non-elderly studies, who, because of general age-related issues suffer from all-around nutritional deficiencies. In other words, we already know old people are sick in a variety of ways, I'm challenging you to support your claim, directed to non-vegans that

> you too, are likely to be running a vitamin B12 deficiency

I want to say it's absurdly untrue and laughable on its face, but I'm willing to eat my words if you can produce a couple independent studies that demonstrate your claim without citing some unattributed nonsense from veganforum.com or other rubbish filled site.
>The thesis is actually that cul-de-sacs increase driving distance, because the places where they are used tend not to have any walkable destinations.

The correlation seems credible, but not the causitive. That is, you probably could build developments where cul-de-sacs are common for streets and where mixed use properties are connected by walking paths.
As someone with a math degree, I love this. However, I think the author over-estimates the familiarity of a typical high school student with mathematical notation:

> The only prerequisite for this tutorial is a basic understanding of high school math concepts

I think fundamentally the material in these four pages is accessible to many high school graduates, but perhaps not in this concise rendering (which is awesome for me, but probably overwhelming for someone not familiar with set-theoretic notation, summation notation, etc.).
- Thank you for this.
Absolutely, happy to answer whatever questions you have.

* Will you only cook what you kill?*

Yep. I have only eaten meat and fish that I (or my close friends) have hunted for the last ~2.5 years. We get a Moose every year, we've gotten a few bison, I go salmon fishing lots.

* If not, will this experience change the type of meat you purchase? (e.g., free range only)*

It's been so long since I even looked at meat for sale, I honestly couldn't tell you how much it even costs. I buy free-range eggs, and prefer local when I can find it.

* Have you or will you now cook offal?*

We always keep (and cook) the heart, a friend keeps (and cooks) the liver. So far, I have not kept or eaten anything else. I'm not against the idea, it's not something I've explored or learned about. I have kept a few of the hides, but getting them tanned is wickedly expensive and I don't have much use for them. I try to give them away.
I don't believe it's a false assumption.

While I'm approaching 50 and still work as a programmer, I've witnessed, over my career, ageism. I can tally thousands of developer jobs (mostly old school mainframe programmer spots, but still, very lucrative paying positions, within the metro Phoenix bounds, where mostly older programmers were let go in lieu of outsourcing / non-immigrant visa holders.

It shows up in hiring, even recruiters inform you to chop off your resume so you won't be thought of as "older".

Just look at the camera panning into the crowd at Google Developer talks -- I don't see many people over 40 in the crowd. A few, but the demographics most definitely skew younger than the average worker. Even here, at ycombinator, PG has stated that older folks just don't have the necessary energy level for startup work.
The article wasn't really aimed at HN, I just happened to submit it here, too. It's aimed at self published authors, who know exactly what I am talking about with "piracy": it's not some married couple sharing a book, it's people setting up sites and systems to widely distribute a book without the author's knowledge or agreement.

I really liked Rebecca's approach, because rather than getting into a rage about her book being ripped off, she kindly, and politely explained how they are hurting her, and what the consequences are for those who enjoy her writing.
A lot of designers are starting to use Sketch. I've played around with it for a bit and I found it much more straightforward than Photoshop or Illustrator (given I'm not a designer). Plus it's cheaper and less resource intensive. I also like that there is a couple of sites where people share their projects, e.g.

http://sketchmine.co

or

http://sketchappsources.com.

That being said, it has a couple of bugs which if you run into are annoying but in no way a deal breaker.
I understand the importance of focusing on the government, but I think use of this sort of data should be restricted for everyone, not just the government. What happens when employers realize that you can filter out less desirable employees by correlating the movements of their social groups and cross-referencing it against credit history databases? We fear what the government can do with the data, but as a practical matter its corporate America that's more likely to actually screw over large numbers of people with this sort of data.
I don't know. I find gittip's model mostly rewards popular coders.

Where as tip4commit, rewards are not influence by popularity. I do see how fluff pulls could drain the pool. One needs to ask: Is changing a typo worth $4 dollars? Is it worth my time to do it? Maybe I should just click that merge button.

In my opinion bountysource is the best reward system, as it gives context, popularity is a boon, and it shouldn't generate fluff.

Just my two cents.
Given the history of man is several hundreds of thousands of years old, I doubt the invented it.

However, it seems they might have innovated and popularized it.

It's not unlike the mafia "protection" model, though, is it not? Take a look at the Crassus model of firefighting [1] which predate the Danes' innovation, for example.

PFTBA greenhouse gas has greater global warming potential than CO2
There are plenty of separate (in many cases, even conflicting) conspiracies out there, planned by disjoint groups, but the problem is most conspiracy theories make it sound like there's a single global organization behind all of it. I cringe every time I hear "freemasons are secretly ruling the world". False flag operations and COINTELPRO are very far (in terms of likelihood and being believable) from "freemasons/jews/illuminati are behind all of it".

I agree 100%

My brother is vegetarian, and bordered on vegan for a few years, my girlfriend is the same, and before hunting I was eating meat maybe once a week or two.

Going into the first hunt, I said to myself "if you can't handle this, then you should stop eating meat". The first time it was a little gruesome and shocking, but it was a fantastic learning experience and I wouldn't have it any other way.
> When the US Army transitioned to "Humvees" replacing Jeeps, the contract included a clause prohibiting resale to civilians. Likewise other equipment cannot be resold, not so much by law but by contract.

Do you know why this is? It sounds more like economic protectionism than a desire to keep them out of the hands of civilians.

He isn't complaining only about poor connections to main streets, he references meandering side streets several times as well... Anyway, every bullet I listed applies just as well to reducing "entry/exit points" as it does to meandering side streets, so I would argue limited "entry/exit" also does not mean classism was behind the neighborhood layout.

Yes, the geeky type will love taking up programming. But most already learn at least some coding.

I'm taking about most people outside that target demographics. I'm thinking about my cousin that work as a mechanician, she can use her computer to go on facebook and look at her emails, but not much else. If I told her "learn coding!" she would reply "learn to fix cars!".

It makes no sense that I would expect her to learn coding and it makes no sense that she would expect me to learn how to fix an engine.

Sure, I know how to change my oil. Well, she know how to defragment her computer.
