I would quote Stevey's Blog here. It says: "The right way to learn math is breadth-first, not depth-first. You need to survey the space, learn the names of things, figure out what's what."

It comes from his own experience. He decided to renew his math skills and declared plan "Math every day". After 15 months he posted another article about results of this experiment. You can read both articles as they are inspirating in many respects.

About his motivation:
http://steve.yegge.googlepages.com/math-every-day

and about his results:
http://steve-yegge.blogspot.com/2006/03/math-for-programmers...

I would add that you should really enjoy math. If you only want to quickly understand one particular thing and seek for some miraculous explanation, this approach will surely not work for you.
Why do you use Windows? I find the restricted interface (e.g. inability to drastically alter the window management paradigm) a real UI deal-breaker.

Ask HN: Another Brand To Beat Apple In The Future
Do you guys think that in the future (5, 10 years) another brand will emerge and defeat Apple in the "coolness" and "in" factor?

Imagine, in say 3 years, every stupid teenage girl will have an iPhone/iPod/Mac and clearly the geeks would like to "separate" once again via a sleek electronics brand that not many people have.

So, the question is, do you think such brand will/could emerge? If so, what would you expect it to fell/look like?

Maybe there's substantial wealth to be created in starting another electronics underdog brand now (but doing it differently). Look at the existing notebook brands now - Asus, Lenovo, Dell etc... - they ALL suck - they provide horrible experience usually and all fall in the same group defined as "not a Mac".
With Javascript disabled, the sidebar notes are completely disfigured. I love the Noscript plugin, and more webdevs need to think about us.
I presume he means he puts all users who arrive on an even day into the control and all users who arrive on an odd day into the "show a phone number" bucket.

You then use cookies to track which user is in what bucket, because you have to know which treatment the user was in when they converted. As you said, that may or may not be on the same day they were treated.

That's still kind of weird, though. You should just randomly assign each user as they arrive to one group or the other.

If he's doing what you're suggesting that's bad methodology for all the reasons you said, and I wouldn't trust the results.
That's interesting, but what comes to mind is that it cannot be just about finding word/object pairings as both word and object boundaries have to be learned as well. They are not distinct entities to start with, and I think reducing them to distinct entities in data mining models is a very limiting (but maybe necessary?) factor.

Quine's "Word and Object" is an interesting treatment of this subject. I wonder how recent neuro and behavioural science relates to what he had to say.
Apparently, they already are:

Okay, crazy question; can (relatively) old adults take A-levels? It might be fun to try to pass tests in things I've never taken formal coursework in like psychology or European History. I did some snooping for US AP tests and at first blush it looks as though taking the tests is restricted to high school students, but perhaps one of the A-levels offering territories is less restrictive?
Palm.

Disclaimer: I work for Palm. That being said, I actually believe it. The Pre rocks, and it's just the beginning. Plus, if the Pre works out, I'm sure we'll have a lot of motivated, intelligent people (maybe even from HN) willing to come help us out.
Have you considered asking new users to enter their first and second names, and creating an available username from that?

This is often credited for Facebook having more 'real' content than MySpace and Friendster.

Git is Awesome because it is a Mercurial with easily editable commit history, "better" local branches and the killing feature -- git-svn.
I honestly hope that HN news does not degenerate into another reddit or digg-like news sites where comments and content are full of dramatized and useless material.

So far, I've found the users of this site intellectual, technical and insightful in their comments and as a result, its been a joy to participate in this community and I hope the crowd which this site attract remain the same - smart and technical people.
For python, if the work is simple, we use web2py and if we need something scalable or complex we build the stack ourselves based on the combo of dejavu and cherrypy. Lots of components are available in python for different segments of a web application.

For web server/dispatcher/controller I think cherrypy beats them all. Cherrypy alone can take you a long way. For ORM there is sqlachemy, dejavu and storm. For forms there is formencode, for json you have simplejson... let me know if you need something else...
The problem is more in the comments. The character of the submissions hasn't changed much.

The best way to deal with nasty comments by new users may be just to ask them to stop. Several times lately I've noticed established users doing that, e.g.

I think it makes a difference if you want to learn a language like Russian, in which there is a great wealth of written material, or Arabic, where there is not. For Russian, you have to bite the bullet and learn the alphabet. However, for Arabic (and Persian) another alternative has grown up in the past year: Arabizi. Arabizi is the use of the Roman alphabet plus four numbers to transcribe Arabic. It grew out of the need to send SMS messages on mobile phones. It is read left to right, not right to left. Moreover, everyone can read it. This means that if you need to write a street address, you can write it in Arabizi and a cab driver can read it. You can memorize vocabulary as you work on your spoken fluency in the language. A friend of mine told me that Greek kids are using the Roman alphabet to send SMS's as well. Eventually, you can work on the traditional alphabet, but for the beginner seeking to learn Arabic, Arabizi is the way to go.
"pg"? Am I missing something?
It seems unlikely. Apple is the result of a unique combination of circumstances: a CEO who is both terrifyingly effective and also has a great sense of design. There are very few people with both those qualities. Even if boards of existing companies consciously tried to pick CEOs with design sense, they wouldn't be able to, because you can't recognize it unless you have it. So the only way you could get another CEO like Steve Jobs would be the way he himself got the job: by founding the company.
Enforcing specific types of usernames is rather lame. People would just enter fake names. Facebook depends on your real identity so people who have met you can locate you.

Good idea. I should add some kind of welcome page.
Exactly. The company needs to be a start-up where the founder will create the device mainly for himself - as his dream device. That's where it starts....

I still think there's a huge revolution coming to consumer devices. Right now, everyone's focusing on phones - namely iPhone killers and they will fail, because the answer is different - and part of the business problem is having such a unique brand that might stand up against apple and that you can build on top of it - when you see people with their Macs open and see the glowing Apple logo - this is a powerful indicator and there has to me something more to this, new, powerful and very unique...and new technologies such as flexible OLEDS etc can be building blocks..

Good thing is to start with a niche target (say 1 million target users) If the new start-up focuses on creating a super hackers device - now they would be on to something...

One of the step I'd like to see is a phone manufacturer taking is what I think to be the next logical step in mobile technology, where your mobile device (phone) integrates with a desktop device (PC peripherals) more readily.

What I mean is that your phone would become your device for surfing the web, working on documents, email etc - that you could sit into a dock of some form that would create the Personal Computer experience wherever you are and when you're done, you just take your phone with you.

This would be enhanced with cloud storage and services obviously.

Gmail accounts are way better for throwaway-give-to-spammers. I forward all mail to myself and autolabel, mark as read, archive.

You're doing it wrong. It's like trying to clean up a messy warehouse - if you walk in and start picking up things, you'll despair very quickly, because the task seems to massive and complex. If however, you simply pick up a tiny corner, and clean it up only, then move to the next corner and so on, the task becomes manageable.

Address this problem the same way - start implementing, and deal with each problem individually. For example, you may want to start with loading a bitmap and breaking it up into a matrix. Make sure that works first, test it also. Then do the quant comparisons or whatever else.

Break the problem into chunks and then only face one chunk while ignoring the rest. Do this in the context of actually working on something with a result, and you'll find that things become way easier and more interesting.

Trying to start by learning several years of mathematical theory is an exercise in frustration.
I use gmail hotkeys to deal with that annoying dropdown.

What they need is a "mark as 'foo'" hotkey that is similar to the "go to label" hotkey (currently in gmail labs).
Try a maths for engineers course at your local Uni.

I don't know if I'd pay for just my list of bookmarks (I don't have that many), but I might pay for a monthly DVD archive of the site's content for all of my bookmarks, plus a searchable index. I hate when I can't find a bookmark, or a bookmark has gone offline.
This may seem like a trivial point, but if a link is going to run video or audio without warning, please can you put "(video)" in the title?

When I browse I open up to 30 or 40 tabs at a time, then go through them breadth first, opening more tabs, continuing in this vein for a while. There have been times when I've had 80 tabs open, moving through them systematically, letting the browser loads the next page while I'm reading this one.

Eventually the tree of pages/tabs closes down as links I opened speculatively have nothing of interest, and so I get my browsing donw efficiently and effectively.

Until some video starts up. Or worse, two. Now I have dozens of tabs to search through to find the one (or two) that are playing something at me without being asked, without giving me warning. It's really annoying.

I know I'm unusual in the way I browse, and maybe I just need to get used to it. But perhaps it would be useful to others as well.

Thanks for reading, sorry about the rant, I hope someone sympathises with me.

Oh, and I upmodded you. Just because the method of opening and lack of warning was irritating, that doesn't mean it was uninteresting. Thanks for the link.
From the 'Hacker News Guidelines':

I think most entrepreneurs tend to be entrepreneurial from a young age. So, if you're one of the ones that are thinking of starting a business and haven't pulled the trigger yet, most likely you never will.

Sad but true.
You learn something new every day.

Though I must say that "usually" doesn't really ring true to my ears. Perhaps it's the way nutrisionists talk, but is it really "usually" that way?

If someone presents a jug of a liquid and says "luckily for babies, liquid X is 50 percent fat", then I'd think that about half of the jug would be fat. Would most people where you come from think "half of the nutritional value of this liquid is made up from fat"? That's sounds impressively educated! Where do you come from?

Even the newer editions feel dated, but the advice is timeless. I summarise it for my self as

"Have respect -

Be honest and genuine."

Always consider how what you say might make someone feel. This can become a habit, and cost you nothing. The gains can be awesome.

There are parts of the book to be taken with a pinch of salt, but if you can read it while keeping its context in mind, it's a gold mine.

I've also noticed comments modded down to <1 for no good reason. I like the idea that here, generally downmods to <1 are reserved for abusive or off topic comments, rather than just something you disagree with.

Is it possible to change your username somehow? I'd switch over to using first name/last initial or first initial/last name if it is. I like being held personally accountable for what I write here, and the real life conversation standard.
I like the idea. "Reply all" is for twitter or a wiki. My inbox should consist only of messages that were specifically adressed (or in rare cases bcc’d) to me.
I do too, it's probably not as uncommon as you would think. I even have a theory that this is one of the major reasons firefox has managed to chip away at IE's market share since MS only recently implemented tabbed browsing.

I recently installed flashblock, which prevents flash from starting and puts a placeholder instead. You have to click the placeholder in order to start the flash file. This solved the auto-playing problem for me, and had the nice side effect of freeing up memory in firefox.

A burned DVD full of bookmarks is, indeed, an insane amount of data.

At about, say, 2K per bookmark, that's a couple million bookmarks. If one bookmarks a site every 60 seconds, 24x7 that's about 4 years of work. A slightly more reasonable person, bookmarking every 60 seconds for only 8 hours a day, would have to be bookmarking websites continuously since about 1996 to fill up a DVD.

I'm a big fan of Richard Branson, and his books read fun with lots of insight. Losing My Virginity had lots of fun wisdom and anecdotes. One of his first rules of doing business is to make it fun, which works for obvious reasons.

He puts a lot of time into customer/client experience, and it really shows. I went to a Virgin Active gym in London for a month, and it's so exceptionally well built down to the little details. They have a sauna, steam room, swimming pool, and a more shallow pool of water that's a cross between Roman-style baths and a jacuzzi.

The detail that impressed me the most? In the shower by the sauna, there's a device that quickly fills a bucket with cold water, and then you can pull a rope for it to fall on your head to cool off. My friend was giddy to show me the pullrope cold water bucket, because it's very cool and you remember it, and want to show and tell other people. Also, a cafe with free wireless and lots of computers, with great quality food that's only about 10-20% more expensive than equivalent high end food outside the gym. Lots of people hang out in there after working out, and they eat food, and Virgin makes more money. Some people might even lean towards signing up for Virgin because of the computers, which means more membership fees.

Guy is brilliant, charismatic, and also seems a legitimately good dude. One of the few people that I never tire of reading or watching interviews with.
You can't deny mini-computers did LED on mainframes, then networked PCs did the same to minis and x86 Windows desktops LED-ed RISC Unix workstations into oblivion.

Free software and web applications look, indeed, a lot like a low-end disruptions into Microsoft's software business. Just because ESR predicts Microsoft's demise since ever, it doesn't mean it won't happen one day.

Still, I think Microsoft will become a very different company in the next five years.
Actually, there was a version of Windows 3.51 running on Alpha processors that was 64-bit-enabled (as the Alpha was 64-bit with no 32 bit legacy).

64 bits is nothing new. I read my e-mail on 64-bit computers back in 97 or so.
reply-to-all is probably the major cause of e-mail overload and congestion so I think that this is an excellent idea.

It's basically a question of overall effectivity, meaning that the time spent on reading non-important e-mails should be kept to a minimum.

To play with some arbitrary numbers here's an example:

I receive an e-mail sent out to everyone in my department consisting of 50 people, and hit reply all to make a pun, correct a spelling mistake, or some other trivial matter. It is easy to hit reply all, and thus I do it since I think my pun is the funniest thing since LOLcats. Now there are 50 people who have to read my e-mail, or at least deal with it. If they on average spend 30 seconds doing so that is half an hour of productivity that has been lost. If ten e-mails go back and forth using reply-to-all (someone else might have an even funnier joke, and since you set the tone they will also hit the reply-to-all button) that is 5 hours of productivity lost.

If you really need to reply-to-all you can easily copy-paste the adresses. This will maybe take you two minutes, and will thus result in an overall fall in productivity of two minutes. A pretty stark contrast to the five hours...
