radagaisus··on US 50 states redrawn as equal population (2012)
As an outsider, the easiest hack to me seems to break down states in your team’s colors to multiple states. Fight fire with fire.
radagaisus··on AI Winter
With just incrementalism there’s still enough value to extract from the current methods of deep learning to propel a small country into a golden age. Leaps and bounds are needed to get to AGI, but winter comes when there’s no more money on the table, not because we can’t reach our scifi fantasies.
radagaisus··on YC 120
This is frustrating and borderline cringe-inducing to read. YC clearly has their eyes on tapping introvert talent. That's a good thing. What’s not is trying to use the same stale tools and programs to catch them. Hint: this is not the crowd that will be comfortable talking on camera, about themselves, answering such bombastic questions. Try again.

Please don't use this. Tooltip Tutorials are a user experience disaster. If you feel the urge to add this to your site - don't. Close your eyes and imagine Clippy. Breathe deeply and create a user interface that won't need this.

radagaisus··on The software development final exam: Algorithms and Data Structures
That's a great textbook summary, now for applications:

You got an array of your friends, an array of people who upvoted this post and an array of people who replied to this post. Filter all your friends who upvoted and replied to this post.

Now, before you write the code, how fast/slow will it run? for 1,000 friends? 1,000,000? will the runtime grow extremely fast? why?

Here's a Redis command that intersects two keys - http://redis.io/commands/sinter - the complexity is "O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets." - do you understand why? do you understand when it will be fast and when will it be slow?

radagaisus··on The software development final exam: Algorithms and Data Structures
from all the questions this is the one you MUST know if you want me (or anyone) to trust you with a piece of code. It takes one hour (in wikipedia!) to learn everything you'll need for a day-to-day work complexity assessment with the Big O notation.

They asked us this questions on our high school final exams, I'm sure you'll manage.

radagaisus··on Reading Other People's Code
Here's a few sources I really liked:

* Express - https://github.com/visionmedia/express - I don't like TJ's coding style, and general trolling of CoffeeScript, but this is a really great, clean and tiny codebase. (As well as all the connect middlewares - https://github.com/senchalabs/connect)

* Async - https://github.com/caolan/async - is very readable. Async is a great library for async ops handling in JS, and it's really neat seeing the implementation patterns.

* Ray - is a games DSL in Ruby - https://github.com/Mon-Ouie/ray - I love it, and it's a great read especially if you are interested in DSLs as much as I do.

* Jekyll - https://github.com/mojombo/jekyll - really helped me going forward with my ruby skills. It's nice, clean, commented, not too big, and useful.

* Redis - https://github.com/antirez/redis - lots of data structure implementations. Antirez just writes C so nicely. anet.c has networking, TCP bits, ae.c is an event loop. Lots of great code there.

radagaisus··on Something is wrong with my generation, i.e. what happened to the social network
“This is me, this is how I have fun, and look at how cool I am.” - That always was and always will be what people want to convey about themselves. For some people it will be a feed of food and cars and partying, for some it will be tweeting complex gists in functional languages.

"we were supposed to be sharing meaningful content" - What, who decided that's what we are supposed to do?

radagaisus··on The Really Easy SEO Link Building Strategy For Startups
GitHub Wikis have tons of lists of 'Apps using this library'. That, right there, is lots of link juice and promotion if you use a lot of open source libraries.

radagaisus··on How To Cheat On Facebook Apps Permissions
How is this a flaw? Go to your Facebook apps settings and you can disable extended permissions for any app there. The apps are expected to work with only some of the permissions, and they have APIs to check which permissions they have enabled. This is intended.

Edit: There's also an option to edit/disable the extended permissions during the authorization. Docs: https://developers.facebook.com/docs/opengraph/authenticatio... (Permissions section)

radagaisus··on Stack Exchange is not a forum: the role of “niceness” on a Q&A site
StackOverflow has been overrun by anal people. Internet power attracts this kind of douchebags like moths to light. If you write 'Hello,' in questions the system will automatically delete it, if you - god forbid - write 'Thanks!' other users will edit your question to remove it. I can't explain how fucking weird it is that people take time to remove the word 'Thanks' from a website they don't even own.

StackOverflow is a crazy good system for Q&A. Just like in Wikipedia, the problem is no longer trolls - but bureaucracy and pedanticism of the moderators. People are assholes who like power, and I don't think any q&a software can solve this.

radagaisus··on 9GAG (YC S12) Raises $2.8M
My impression is that 9gag is a social fad. Memes became mainstream and the 'cool kids' (the early adopters) are already making fun of le upboat XDD I mustache you a herp derp.

9gag is pretty popular in Israel[1]. My coworkers (20yo) still read it, but it was all the rage a few months ago, and in a family dinner my 13yo cousin asked me if I know the site. All this indicates the eternal cycle: 'knew them before it was cool' -> mainstream -> 'omg are you still into that?'

Dubstep (recent example) stopped being cool because it went mainstream. Memes will not stop being cool - image macros are the laziest way to get information - but 9gag (unless they do something crazy) will become just a site. Remember the esoteric tumblrs?
