carlosrr··on Why every programmer should have a Tiddlywiki
I like nvALT (http://brettterpstra.com/project/nvalt/) as a replacement for notational velocity. It is a fork of NV that adds many features.

TODO list, fullscreen and markdown support are amongst the ones I use the most.

carlosrr··on "Auction Site" Swoopo got $44800 for a $2500 computer. See comments for explanation
Something that needs to update so frequently shouldn't poll for its data. It would be a better idea to create a Comet server. That simplifies synchronization since you don't have to query the DB every time someone does a request. Instead, you query it every time someone changes a field.
carlosrr··on Ask YC: Would HN readers be interested in a HN events site?
Me and my friends created groupieguide.com for managing these kind of things. We would be more than happy to help setup something like this.
carlosrr··on Defending IE6
He is not advocating that you get your great UI to work on IE6. He is advocating that you get a lame UI just for IE6 users.
carlosrr··on Ask HN: We launched our startup (GroupieGuide) today. What do you think?
I think you hit the nail right in the head when you mention all these different services. There are many products out there that expand our features, however using and mashing these products together ends up with a complicated and difficult to setup service.

We picked features that are useful for non-techies and made them accessible through a single interface.

carlosrr··on Ask HN: We launched our startup (GroupieGuide) today. What do you think?
We think that there are many users that want a web page for their group but don't want to interact online. GroupieGuide is a gets out of the way solution where most of the interaction can be done over e-mail. Visitors don't need to navigate to get the information that they need.

Both ning and tangler focus on building online social interactions through the website. We are trying to cater to the users that have been ignored by social networks.

carlosrr··on Atwood rebuttal: Mandarin Chinese programmer communites
I did not mean that people would do a literal translation. I think that people can translate the _value_ of the content into other languages.
carlosrr··on Atwood rebuttal: Mandarin Chinese programmer communites
It benefits everyone when individuals speak on the language that they feel more comfortable with. If what they have to say is valuable it will be translated to other languages anyway.
carlosrr··on JSON Template
I made a light version of haml for javascript called baconl. It doesn't support embedded code, but I have found that it is not needed when used with most javascript frameworks.

carlosrr··on TextMate vs AptanaStudio
There is an Auto-pair characters checkbox under Text Editing in the preferences.
carlosrr··on TextMate vs AptanaStudio
If you select the 9+6 and then insert the opening parenthesis it will wrap everything automatically. This is not really intuitive, but the extra idiocy is there for a reason.
carlosrr··on TextMate vs AptanaStudio
I agree, seeing all of the documentation on the same page helps you learn other functions that you might otherwise not look at. Also, the higher level the language the less the programmer has to rely on autocompletion.
carlosrr··on Teens capture images of space with £56 camera and balloon
Looks like gravity helped:

"At over 100,000ft the balloon lost its inflation and the equipment was returned to the earth.

"We travelled 10km to find the sensors and photographic card, which was still emitting its signal, even though it had been exposed to the most extreme conditions."

carlosrr··on What makes people cheat? [video]
Like with many other measures to prevent piracy, the crackers would find ways to remove the morality reminders and the paying customers would get stuck with them.
carlosrr··on Super last minute advice for startups applying for Y Combinator
This is a very interesting article about how "literally" is used to mean "figuratively." http://www.slate.com/id/2129105/
carlosrr··on Ask YC: Game programming in Lisp - is it possible?
Lua is a multi paradigm programming language that is very popular with game makers. There's also an engine written in Lua for making 2d video games called Love http://love2d.org/.
carlosrr··on Researchers find ways to sniff keystrokes from thin air
A few years ago there were some papers about logging keystrokes by recording the sounds of the different keys in the keyboard. Keyboard Acoustic Emanations: http://www.truststc.org/pubs/3.html
carlosrr··on HTML Validation: Does It Matter?
HTML validation is of great value when debugging, even javascript. It can discover things that are easy to miss like unclosed tags and repeated ids.

It is difficult to write a whole website, validate it and fix the errors and at this point validating has little value. However by validating periodically you are getting more out of the tools available. I don't force myself to write 100% strict HTML, but minimizing the validation errors means that I will have less to read when it's time to.

carlosrr··on Switched from Capistrano to (Python) Fabric
Vlad is another good Capistrano alternative written on top of Rake. http://rubyhitsquad.com/Vlad_the_Deployer.html
carlosrr··on Ask HN: How do I get through to startups for a summer position?
When I was looking for internships I would just look for startup lists on cities I was interested in. I saw their open positions and sent a mail with my resume and a well crafted cover letter based on what I was interested on. Most companies were very accessible and would at least reply back.
carlosrr··on Ask HN: My 13 year-old cousin hacked into his school's system. What advice would you give?
I thought of the same article.

Also, I greatly enjoyed reading iWoz and it is be very accessible for a teenager. Woz' passion is very contagious and it may help him discover how fun constructive hacking is.

carlosrr··on Adobe software shamefully, frustratingly incompetent
He mentions wanting an open source solution for developing on Chumby. I have used Sprouts [http://www.projectsprouts.org/] for some Chumby projects and I have been very happy with it. It doesn't have a drag and drop UI like Flash (it's more for hackers than for average users) but it is easy to work with and to setup.
carlosrr··on Ask HN: how do you read code?
Github is very good for reading code since it can be done through the browser. If I am going to be using a particular library, I take a look at the commit history and read the code on the more interesting commits.

Also, hanging out on IRC rooms is very helpful. Many people ask for code reviews before committing to the libraries and you get to see how the library evolves and what are the design decisions behind the changes.

carlosrr··on Ask YC: Do any of you find yourself reading comments before the actual link?
I thought something similar when reading this thread and thought it would make a nice bookmarklet.

http://code.cohitre.com/snippets/hackernews.html

It opens the comments and original article in side by side iframes for easy previewing.

carlosrr··on Ask HN: What programming language should I teach my little brother?
ActionScript was the first programming language I learned. I found some tutorials on how to make games and little by little learned by changing the source code. Being able to create graphics was very rewarding and the popularity of flash made it easy to show my friends what I had done. The feedback loop was very important in keeping me interested in programming.

Project sprouts (http://www.projectsprouts.com) makes it easy to get started in ActionScript and is also a good introduction to writing support scripts in Ruby.

carlosrr··on Post a possibly good app idea that you have no intention of doing yourself.
