If you want to DO math, nothing beats working through a decent textbook. I have worked through several since I'm approaching 50 and don't use math enough to keep my skills up (and like any skill, you have to keep practicing to stay decently competent in math). The best Precalculus textbook I have used is Swokowski's "Algebra and Trigonometry with Analytic Geometry" which is clear, concise, and has lots of problems.

If you want to learn ABOUT math, Davis and Hersch's "The Mathematical Experience" is a fairly easy read about philosophy of math, how it is used, and a bit about studying math.

Eric Temple Bell's "Mathematics: Queen and Servant of Science" is a bit dated but an excellent history of math for someone interested in learning to do advanced math; the author's a bit biased towards algebra over analysis, number theory, and geometry, but not excessively so. Its biggest lack is only one short chapter on probability and statistics. This is not a particularly easy read since it covers things in some depth, but I think it is worth the effort.
So now they acknowledge that glossy screen is even $50 _inferior_ to matte.

People have to pay for things in absolute money. :)

Not to mention that absolute savings are important when it comes to carbon reduction.
Invalidates? Absolutely none. Good mathematics is eternal and the Elements has some beautiful mathematics.

What I meant to say is that in the fullness of time they have been expanded on and surpassed. You can still learn good and valid mathematics from Euclid, but you can learn it better form more modern sources.

As one example amoung many, good modern geometry books will let the reader know about the existence of non-Euclidean geometry and its differences, even if the focus is on traditional Euclidean geometry.

Also, modern books will use modern notation. Notation of course does not affect the ideas which are what is important, but someone trying to learn math today will need to learn the notation so that they can read other more advanced books that will assume the reader knows that stuff. Not to mention, notation can make things easier or harder (try doing multiplication in Roman Numerals).

Finally, many things that were proven tediously before have easier proofs developped over time, often with the ability to take recourse in Algebra. For the same reason, many open questions in Euclid's time now have answers.
I was usually interested in my classes, so I usually kinda looked forward to lectures. I only missed three lectures in four years.

Now, as a PhD student (hopefully) close to graduating, the concept of sitting in a class and being told what I should know sounds luxurious.

a MBA from an ivy league school carries more weight than a MBA from the university of phoenix.
> Don't do what I did.

Au contraire, I did what you did (probably to the extreme, I was on academic probation 2x and did more drugs than I can remember), and I wholeheartedly recommend it to anyone if they have the mental fortitude to actually graduate at the end of 4 years.

When you stand on stage smirking and hung over with your degree and mortar board after 4 years of doing whatever the fuck you wanted, it feels like much more of an accomplishment than if you had buried your face in books the entire time.

I can think of at least one person: the manufacturer. If my product is receiving poor reviews on a much-visited and trustworthy site, it would be in my favor to skew my reviews on said website to the high end.

So while there's no reason for Amazon to break the system, there are certainly many others who would.

Generally true but overstated. It seems to consider literature as consisting of serious fiction and of memoir. It omits mention of the huge number of books written to be read as distractions.
Just as a Vespa would have poor gas mileage carrying heavy truck cargo - this has nothing to do with the energy source.
On the other hand, in college it is MUCH easier to date and meet people than in the real world once you start a job or company.

It can be a big shock to start living with someone else closely for the first time. Prepare to compromise.

There will be several times when your roommate(s) gets on your nerves, and I found it best to step back, take a breath, look at specifically is bothering you, and confront your roommate about it calmly. Ask him to do the same if you start to bother him somehow. Patience and good communication are key to maintaining order in your living space. Do this right and dorm/apartment life will be a blast.

On the flip side, your first year can be quite hellish if you've got a roommate that is unbearable. If peaceful negotiations are not working, definitely consider moving out; don't just live in misery.
Not true, idling consumes gasoline. Unless you have disabled your steering lock, and can do without power steering, headlights, AC, or brakes (not recommended :-) ), you are not getting ∞ MPG, even if your car tells you otherwise.
If I went back or could start over, I would study two or more fields that interested me making sure that they weren't closely related. I'd do this because it's not enough to know how to make good tools for programmers. Knowing what programmers need lets us have bunches of good text editors, databases and programming languages. If you have domain understanding that isn't about coding and computers, then you have a chance to fill a void that no other coders can possibly see.

Also, I'd take some graphic design classes because user interfaces matter.
To elaborate: I think we've struck a really good balance at GitHub when it comes to our roles.

mojombo has a background working with distributed systems (at Powerset) as well as in design (he freelanced for a few years). Which means he's our main UI / design person as well as the guy overseeing the "big picture" backend stuff. For instance, right now we're in the process of sharding all of our git repository data to get away from our network file system bottleneck. mojombo's leading that project and it's going great - we should see the plans come to fruition in the near future. He's also the guy that makes changes to the git-daemons and other sysadminy stuff.

pjhyett, one of the other founders, is a seasoned web developer with experience in (among other things) Java and Rails. Which made him the ideal head of our Firewall Install product (since it uses JRuby). He's currently on a trip to NYC to meet with potential FI clients, and is in charge of adding features to it, fixing bugs, basically lording over the product.

schacon isn't technically a founder, but we're a very flat (and small) organization. He's a Git expert so we deploy him on any and all things Git: weird server errors, crazy new projects (like the Fork Queue and Gist), and our issues scaling Git itself. He's currently experimenting with a Cassandra-backed git-daemon to help speed up clones (specifically the "Counting objects" / building packfile phase) and give us the ability to easily put mirrors in other continents.

Tekkub is our customer support expert: he hangs out in irc, on the mailing list, and oversees the help site. He has programming background (we found him because of all his Lua stuff on GitHub) which means he can write his own tools and knows Git very well.

I'm the third founder. I mostly hang out here.
That's a pretty cool site... have you had issues getting people to sign up on either side?
Reasons You May Need Physical Therapy
Gotta give you some solidarity here even though it's the unpopular opinion. As someone who's been Mac-centric for the past few years I have to say: anyone who claims that Apple supports devs as well as MS is on something.

Apple's documentation cannot begin to hold a candle to MSDN, their direct developer support even worse. Developing on MS platforms is a joy - it's straightforward with copious amounts of documentation provided directly by Microsoft.

Developing on iPhone/OSX is a pain. Much of the "documentation" resembles a Obj-C header file, important details hide in gigantic tomes of text with zero sample code to bring it out. Unexpected/weird behavior is rarely documented... the whole thing is a gigantic labyrinth that breeds tribal knowledge instead of documentation.

Ugh.

It is good to see that the MIT takes the interests of the truly paranoid so serious. What surprises me though about the whole affair is that the government allowed this information to be released.

In our circles the fallibility of the tinfoil hat is well known, which is why those are only used in emergencies (an emergency is a paranoid individual emerging from their den or dwelling).

Personally I prefer the 'whole cage' approach. This is a little more involved than the tin-foil hat, but well worth the investment imho.

To implement it simply coat every surface of your house with chicken wire, make sure to make solid interconnections (preferably soldered) every couple of inches where two sections meet, and do not forget the windows (you'll get used to it quickly enough).

I'm still a little worried about my internet connection being used to inject radiation into my carefully constructed cage of Faraday, so I've put all my computing gear behind grounded chicken wire as well.

The only things protruding are the mouse and the keyboard, since the installation of the cage I sleep much better, feel much better in general and my headaches are gone.

I can recommend it whole heartedly.

They wouldn't have needed to bring back matte displays have they listened to their users and not removed this option in the first place.

I don't know why they fanatically remove useful features and options. It's 2009, and I can't even choose a _custom_ color to serve as a wallpaper for Mac OS X, only one of _ten_ colors provided by Apple. It's so unimaginably idiotic to have to create a png file for this purpose.
Too many words! Not the greatest material to hack to, I find it difficult to program while listening to songs with (comprehensible) words.

MBA's are more a function of whether or not you can pay for the program than your undergraduate grades really.
I'm not so sure about deflation, since we've replaced private credit with public credit. But it's nice to see data indicating hyper-inflation is not on the horizon.

And it's interesting to think what the world will look like when Americans are savers and someone else, Asians?, are spenders.
Ask HN: Intern staying on with company, is Salary Negotiation Appropriate?
I've been extremely lucky to secure a paid summer internship this summer fresh out of my freshman year of college in a very exciting technical field.

I've been doing penetration testing and tool development for a startup information security company. They didn't have any internships listed only higher-level job postings. Encouraged by a mentor, I sent over my resume anyway with a cover letter indicating that I was seeking an internship. Needless to say, I got the internship. It's three months later, I have been given responsibilities on an equal footing as some of my much senior coworkers.

They initially offered me a job at the end of the summer asking if I wanted to "take a semester off", but I knew if I left college now i'd likely never go back. Instead they are offering me a telecommuting position.

I've been earning a bit above minimum wage, and this summer has been an awesome experience I wouldn't trade for anything, but how much is reasonable compensation for someone with a LOT to learn (c'mon I'm a rising sophomore), yet still creating immense value for a company? I've had the privilege of leading security audits for Fortune 500 companies who were later very satisfied with my analysis --- this was all closely supervised work and independently reviewed. My coworkers treat me as a peer, and my supervisor is very pleased with the quality of my work.

How much is "reasonable compensation" for a part-time telecommuting college student who's staying on after interning?
You can't pick out the good ones if you haven't been with a few bad ones.

I don't think this is true. I know some people who luck out on the first try. Also, I know a lot of people who seem never to have dated bad people. They've dated some people ill-matched to them, and had some breakups, but they've never dated someone I consider to be a rotten person.

I think there's little to be gained by dating horrible people, except some unwanted emotional baggage. There's a lot to be gained by dating good people who aren't right for you; this is how you find out what you're looking for and refine your tastes.
On my wireless thingy- it has two antennae. I made two tinfoil "dishes" around them. The antenna are always at the focal point so they can receive signals from farther away. It works- but if it is not at the focal point it might not work, so my suggestion is drawing the hyperbola first and then finding the focal point.
I bet it will be something cloud based. Will they sell to Amazon and other cloud providers, or will they build their own cloud?
That depends entirely on the class! I had classes that were easy even if I didn't go to class, and others that were hard even if I went to every class. (I even signed up for overlapping courses once, and skipped out of an uninteresting mandatory one halfway through every lecture to go to the other.) Far more important to me was getting together with other students to work on the material.

That's what college is about: figuring out how you learn best. If you know that, your school/major/etc. don't matter.

I think patio11 has some excellent advice. On top of that, why not partner with someone who is already in US? That way you can have benefits of (one co-founder) being in India and benefits of (other co-founder) being in US.
I live in US and I would love to explore options to partner someone in India. Being Indian myself, I know that there are some business models which have very good potential and require presence in India and US both. e.g. selling westerns clothes (with traditional india designs) made in india over web.

Close, but not quite. The sentence right before their 40¢ a day claim, they say $2.75 per 100 miles. That works out to 82.5¢ for 30 miles, or $1.10 per 40 miles. 82.5¢ is 3 times better than the current $2.60 for a gallon of gas, but grid power is almost double the 11¢/kWh used for these calculations in some parts of the country.

i was using an MBA as an example, as its usually the most exaggerated.

another example is that there is a well known preference inside of google for PHDs from a specific set of schools.
Glossy displays are cheaper to make (since they lack the anti-glare coating).

Most consumers even prefer glossy vs matte (especially when they see them side to side at the shop) because the matte coating (obviously) reduces brightness and colors are perceived as less vibrant. Of course, as soon as you have to work with them (apart from viewing a movie in a dark room) you'll regret it.

Cheaper + clueless consumer = market trend.

The previous generation of MBP had both options. I bought the matte, and the price (IIRC) was the same.

I believe that Apple didn't offer this option for these models from the beginning because the screen of unibody machines has glass in front of it and so the process to add the coating wasn't ready yet or it was much more costly.
Blacks look blacker :/ In the right lighting it looks far brighter with better contrast I think. Just depends on what your lighting is though.

College is a great time to take the next, probably awkward step with the opposite sex. If you don't, you're stuck learning those skills while you're in "the real world", a setting which is generally less amenable to meeting lots of people who are around your age, thus inhibiting your rate of learning.

You have a really strong point here. I guess my argument would be that most of what happens with the opposite-sex is detrimental and unpleasant, and can derail a young man from actually learning and getting some work done.

In an environment where earnest dating still exists, respect between the genders is the norm, men are prized for their intelligence, character and culture rather than shallow traits such as social status "game", and sleazy hookups don't happen, I'd argue in favor of entering the dating scene as soon as possible. In that arguemnt, I'd argue that everyone (who's single) should jump in. Unfortunately, that's not the type of environment that exists on most college campuses (although I know nothing about Olin).

if you feel like you deserve a raise, ask for one. however, understand that many companies have a policy set in stone for interns. you might not be able to get anything more within the employment structure you're currently in.

however, if you like this job, you could use this situation as leverage for a much higher starting salary if you want to continue working with them after graduation.
Campaign Monitor was a shell service: something numerous agencies resold to their clients, unbranded and often masked. More than one designer will wake up to the news that they’ll have to call a client who trusted them, and explain how a service the client may never have realized was responsible for their information is now at fault for damaging their relationships with their customers.

Could the agreement by FriendFeed, to sell to Facebook have been pushed along by the possible emergence of the supposed FriendFeed Killer by Apple, dubbed iFriendFeed (http://www.techcrunch.com/2009/08/11/apple-planning-some-sup...)? Maybe. If so, the company may have cashed on on that $50 million just in the nick of time. But still, Facebook also benefitted from aquiring those former Google Vets that can enhance their creative social media service quite a bit.
Good to know. I'll switch the player up this evening.
Your questions are about resource allocation, and the answer as usual is free markets. An argument about the efficacy of free markets vs. central planning would be offtopic, so let's just agree to disagree on this one.

Here’s a self-enforcing protocol for determining property tax: the homeowner decides the value of the property and calculates the resultant tax, and the government can either accept the tax or buy the home for that price. Sounds unrealistic, but the Greek government implemented exactly that system for the taxation of antiquities. It was the easiest way to motivate people to accurately report the value of antiquities.

I had an idea a while ago about stopping domain name squatters by using a similar protocol to price and tax domain names. You'd be required to report the "fair value" of each domain you owned. All your domains (maybe there could be exceptions for trademarks) would be implicitly for sale at that fair price. To keep the reported price from being too high, you'd have to pay some fraction of that price as a yearly domain name tax. That way, if anyone has a better use for your domain than you do, they can just buy it from you. Of course, if you build a brand and a trademark, you should have some protection from competitors just buying your domain. Maybe only other similar trademark holders could compete for your domain (eg, Apple Computers and Apple Music could fight it out to see who gets more value out of apple.com).
