# Trevor B's Messageboard

Hi there! My name is Trevor B. I've been on Brilliant for about a year now. A lot of great stuff has happened because of it. I've gotten a lot better at math, learned about computer science, interacted with a lot of great people, and I appreciate all that the community has done for me.

This is my messageboard. If you have a question for me, go ahead and ask. I'm excited for your questions. Thanks!

What Sources You Used for Learn Programming?

- 3 years, 7 months ago

I used Codecademy. It's a great site for learning new programming languages. I'll be learning Java after I get through my AP exams next month.

One of the things that's funny about it is the question set when you arrive to the site. I won't spoil the surprise ;)

- 3 years, 7 months ago

Why do you want to learn Java?

- 3 years, 7 months ago

I hear that it's a pretty good language to learn. It complements Python pretty well.

- 3 years, 7 months ago

Yes it is a very useful language to know,especially if you want to get into hardcore development(apps/applets/etc..). I learnt a little bit a while back. It is structured around OOP so if you are familiar with it in python it should be easy to catch. I myself am thinking of learning LISP or Haskell,they are very cool languages. If I have some time maybe even one of these .

What Sources You Used for Learn Programming?

• I Know That You're Very Good In Programming !

- 3 years, 7 months ago

I learned how to program back in 8th grade I think on some website(I dont remember which). I didn't have internet back then so I used to write small programs,scripts and games when I didn't have much to do. Eventually I began to do large projects with friends(software projects/websites/AIs).I also practiced on hard problems on projecteuler/topcoder/codeforces..etc. Thats basically It : practice. I wouldn't call my self very good though,there are many programmers better than I am here.

@Ivan Koswara,@Brian Chen I really admire your solutions,maybe you guys could share your sources and experience with CS?

- 3 years, 7 months ago

My dad used to be a CS professor, so I was exposed to it early. I learned my first language, Java, from a Deitel book, and later from various parts of the official Java tutorials, but I've almost entirely stopped writing it; instead I spend my time with Haskell, Scala, C++, Python, and occasionally JavaScript and some other languages, all of which were completely learned online. I also read Introduction to Algorithms and participated in programming competitions, both online (CodeForces + TopCoder, as mentioned) and locally, as well as going to training camps and sites. I have a few silly personal projects on GitHub. That's pretty much it.

- 3 years, 7 months ago

What did you use to build websites? There's a website I want to make but I don't know what I'll eventually be making it in.

- 3 years, 7 months ago

It was a simple complementary website for a software we developed so I didn't involve myself with it too much,I was building the software. We used a web builder(similar to frontpage/dreamweaver)..If you are building a large website with a lot of functions you can use a webframework like django which has great tutorials at neckbeardrepublic.com. @Beakal Tiliksew can give you details b/c he was in charge of the website.

- 3 years, 7 months ago

I am no expert in this field, But HTML 5 is the best. Good for beginners, not to complex but extremely powerful.

- 3 years, 7 months ago

I Don't Have Classes of Programming ! By This That I'm Trying Learn With Sources of People Experts !

Thank You ! All the Best !

- 3 years, 7 months ago

That is what I am doing to.

- 3 years, 7 months ago

HAHAHAHAHAHAHA yes that's my favorite part. :D

- 3 years, 7 months ago

I'm not too great at programming, but I can totally recommend Codecademy! It's excellent for interactively learning tons of languages as well as a good interface for writing code. It's also really addicting and fun.

- 3 years, 7 months ago

This Site I Already Know ! Thanks !

I Need of More Sources !

- 3 years, 7 months ago

Oh, in that case, Khan Academy can teach you a lot about JavaScript. Its interface is also really clean and it doesn't bug easily, so I've used it a lot.

- 3 years, 7 months ago

Actually Khan Academy uses a sub-library of JavaScript,called processing.js I think

- 3 years, 7 months ago

Possibly.

- 3 years, 7 months ago

What do you think of this problem? if you like it please share it or/and participate.

- 3 years, 4 months ago

What Are Your Top Study Sources?

- 3 years, 7 months ago

Art of Problem Solving is a really great site. I also like using OPLET to get an unlimited source of MATHCOUNTS problems, but it costs money. And of course, Khan Academy.

- 3 years, 7 months ago

I'm sorry, but I'm not sure I understand the question. Do you mean for math or just for school in general?

- 3 years, 7 months ago

(This comment is not suitable for teachers. Viewer's discretion advised)

Ok, so basing off of what Finn says, I'm going to answer this in a math context.

I do what I call Wikipedia surfing. I pick up some concept, somewhere. It doesn't really matter what. I look it up on Wikipedia, learn about it, and move to the links in the page that Wikipedia gives you. I do this a bunch, and then (Teachers can begin reading here) I go on sites like AOPS and Wolfram Mathworld and learn about them there.

- 3 years, 7 months ago

i do that too! :D ^5 wikipedia surfing ftw :D

- 3 years, 7 months ago

I don't go to Wikipedia. Seriously, the articles on Wikipedia is too hard for me. I would prefer Wolfram|Alpha and AoPS. For example, try search

• Factorials Wikipedia
• Factorials Wolfram
• Factorials AoPS

and compare. The article on Wikipedia is insane! You read all of it?

- 3 years, 7 months ago

I agree with you, for example any mathematical concepts you search in Wikipedia it uses calculus to teach you.So I don't prefer Wikipedia, while wolfram and Aops are the best.

- 3 years, 7 months ago

Oh, yeah dude I feel you there. But Aops is still the best out of all of them.

- 3 years, 7 months ago

Exactly what I do.

- 3 years, 7 months ago

For Mathematics and Computer Science !

Can Be Books , Sites , Magazines and More !

- 3 years, 7 months ago

I learned Python from Codecademy, but I don't remember if I got it from anywhere else.

As for math, I have a ton of math books at my house, such as Mathematics Without the Boring Bits, Sciencia, The Joy of X (though this one is less math as it is an entertaining take on pre-college math), as well as a bunch of chemistry-related books, like The Disappearing Spoon and Elements (by Theodore Gray, who is completely awesome, and the one from Euclid is on my next birthday's wish list. I can never remember my birthday and what I want for it and I always end up having to wait another year).

As for sites, I use Brilliant mostly, as well as what I said with Wikipedia.

I have a rival in my class. We challenge each other with tough problems and try to one-up each other. Were both always trying to get better to be prepared for anything the other throws at us. Competition is a great way to learn as long as you don't let the idea of a competition stuck in your head. We are using the other to get better at math.

- 3 years, 7 months ago

Can you list more chemistry-related books you felt interesting? I can't find any :(

- 3 years, 7 months ago

I wish I could... It's a shame I've only gotten really interested in chemistry in the last six months, which have been the busiest of my life. As with learning chemistry, I'll find some over the summer. Sorry I couldn't help you here.

However, I went through my library, and I forgot to mention the Visions of Infinity is an excellent introduction to some of math's greatest problems, such as Fermat's Last Theorem and the Riemann Hypothesis.

- 3 years, 7 months ago

I found your calculus problems quite intriguing and healthy. Can you give me some tips on improving my calculus?

- 1 year, 10 months ago

What math class are you in?

- 3 years, 7 months ago

AP Calculus AB, but I'm sort of teaching myself Multi. The notation on Wikipedia is hard to get at first, and I don't have any books for it, but I'll find something eventually.

- 3 years, 7 months ago

Nice! You're in 10th grade, right?

- 3 years, 7 months ago

Yes. I'll be taking BC next year and then Stats and Multi senior year.

- 3 years, 7 months ago

Cool! I'm in Algebra 1 in 7th grade right now, but next year I'm accelerating into precalculus or trigonometry. Possibly calculus AB if I have enough time to test in.

- 3 years, 7 months ago

I won't advise Calculus AB in 8th grade. You need 4 years of math to pass high school...

- 3 years, 7 months ago

Yeah haha, I'll be writing my thesis paper in 11th grade. :D

- 3 years, 7 months ago

Hey Trevor! Is there a reason besides privacy that your last name is abbreviated?

- 3 years, 7 months ago

No, it's privacy.

- 3 years, 7 months ago

Are you sure it's not because it's some wacky 3-syllable name? :P

- 3 years, 7 months ago

No, that's not a reason.

I guess another reason is for nostalgia's sake. What I have used to be how Brilliant displayed names.

Okay dude, totally sorry about that, I thought you said you didn't have a really long funny last name. Dude I am so sorry. While I'm on the subject, did you know that Calvin's real first name is Zhiwei? I read about him on the IMO website. He didn't do too well, but he was representing Singapore which is INCREDIBLY hard to do. :D

- 3 years, 7 months ago

I do have kind of a funny last name, but that's not a reason (even though sometimes I'm not even sure how to pronounce it, but that's a long story). Lots of people on Brilliant have names that are hard to pronounce. It's for privacy and nostalgia.

That's interesting about Calvin. My opinion: if you can make it to IMO, for any country, then you're pretty darn good at math.

- 3 years, 7 months ago

Haha, yea, part of the reason is that I stated (seriously) training very late. While I had the aptitude and ability, I was focused on other activities earlier on. I only joined the Singapore IMO training team when I was 17, and had large holes in my education. I was lucky to be selected for the team, and had a great time at the IMO.

I would have done much better if I went as a contestant in 2005. I was training the team that year, and accompanied them as an observer.

Staff - 3 years, 7 months ago

For the US, IMO is what comes after USAMO, right?

- 3 years, 7 months ago

Nope, you still have to qualify the TSTs as far as I know.

- 3 years, 7 months ago

Dude, that's still insane. Great job doing that! :D

- 3 years, 7 months ago

Yeah. Sometimes, I consider moving to some place like Rwanda just so I can go to IMO for that country. I'm so sorry if I infiltrated your privacy in any way, I didn't mean it, and if you ask me you have an epic last name. If it makes you feel any better, my middle name is Edward. :P

- 3 years, 7 months ago

I don't think there is IMO in most of the african countries, i have checked on mine

- 3 years, 7 months ago

Yeah maybe not. South Africa is pretty good though, right?

- 3 years, 7 months ago

The south africa is the pretty good, i can't say half that much for mine, but l love mine, live long ethiopia:)))))

- 3 years, 7 months ago

Dude I really want to visit Africa. It just seems so epic.

- 3 years, 7 months ago

I don't think Rwanda is the best place to go... (Put it in a google search bar and see what the auto-finish is). But you're only 13 and you have a lot of time to get better at math, so you might compete later on. Certainly you'll make it to the AIME and maybe even USAJMO or USAMO.

- 3 years, 7 months ago

Speaking of Google auto-finish, try this. This is the ultimate proof that language matters!

Try typing "How can u" into the search bar and see the auto-finishes.

Now try "How can an individual" and see the difference!

Language does matter! :)

- 3 years, 7 months ago

HAHAHAHAHAHAHAHA that's really funny. :D

- 3 years, 7 months ago

I saw you upvoted this, but did you send the email? Note that there is a period between my first and last names. Or if you don't want to send it, that's fine too.

- 3 years, 7 months ago

Yeah I sent you an email.
