Throttling download speed for a certain port

Taken from gentmatt’s (http://apple.stackexchange.com/users/13414/gentmatt) answer to: http://apple.stackexchange.com/a/46378 .


OSX provides ipfw to define custom firewall rules. Using this tool you can create a pipe with limited bandwidth.
Create a pipe “1″ limited to 500KBytes/s via
sudo ipfw pipe 1 config bw 500KByte/s
Guide all network traffic of port 80 through pipe “1″ using
sudo ipfw add 1 pipe 1 src-port 80
When you don’t need the pipe anymore, remove it from the port using
sudo ipfw delete 1

If for some reason (website testing etc.) you need to limit your download speed and doesn’t want to install additional software. Works great! (mbp osx lion)

Read blurred answers on Quora

To keep things short, here’s an easy way to bypass the impenetrable sign-up wall on Quora (impenetrable because you can’t sign up even if you wanted to) and read the blurred answers.

With the question page currently displayed in your browser, open your browser’s console (cmd+shift+J on Chrome, cmd+alt+K on Firefox), and paste these lines:


$('.signup_cta_on_answer').remove();
$('.text_hider').remove(); // enables text selection
$('span.blurred_answer, span.blurred_answer a').css({'color': 'inherit', 'text-shadow': 'none'});

Yahoo! Open Hack South East Asia 2009 results

At last!

In case you didn’t know, Yahoo! just had its first Open Hack Day in South East Asia 2 days ago (Nov 21-22). The place? Balai Kartini, Jakarta, Indonesia. It consisted of two main events: The Tech Talks (Nov 21st 9:30 – 16:00) and the Open Hack itself (Nov 21 13:00 – Nov 22 13:00).

Nothing much to say on Tech Talks except, the speakers from both Yahoo! and Koprol (Koprol is a fast-growing Indonesian startup company and also Yahoo!’s highlight at the event) were giving talks on various topics (Yahoo! services and APIs mainly). There’s Jon on YAP and YOS, Shreeni on YQL, Angela on YUI, and Alfred on Mobile Blueprint.

Some of the slides from Tech Talks are available here:
YAP and YOS: http://www.slideshare.net/jcleblanc
YUI: http://whimsical.nu/hack/yui-slides.pdf

November 21st, at 13:00 sharp, the 24hours countdown timers are set and participants are away with their own business. After a long session of discussion, countless keyboard taps, hours on top of bean bags (which is nice), overflowing snacks and candies and chocolates, midnight “Jamaican Cafe” acapella band performance (great people), souvenirs giving, keyboard taps (again), some frustation tweets (server is not curl-enabled??? FUUUU-), bottles after bottles of RedBull (FTW!), and the terrifying presentation session (in which I messed up), — the judges are ready break the news.

This blog is not dead (yet)

Contrary to the popular belief (ha!), this blog (and me) is not dead (yet). Works and constant distractions (and the lack of writing materials) have made this blog stagnant and I’m not proud of it.

I’ve been wanting to put more codes/tutorials here to compensate for the scarcity of posts but currently have no idea on the topics. (not to mention that I have to overcome embarrassment of posting my own code first) So yeah, might be best to see for ourselves later.

Oh, and, I’m looking forward for the Yahoo! event (OpenHackDay — there is a sign-up link here if you are also interested) that will be held on 21st-22nd November (damn, that’s next week). Gotta study hard.

Alright…

A: Hey, the codes I got from the web don’t work. Could you check them out for me?

B: (stops typing) Okay, where?

A: Here.

B: Where’s the error at?

A: Dunno, it just don’t work.

B: … Where did you got this from?

A: Wait a sec… Here’s the URL.

B: (opens page) Hm.. Okay, here’s the explanation of it: (read aloud) .. is that what you need?

A: Hmmmmm.. not really.

B: Then why did you use it?

A: Hm.. I don’t know.

B: …

On blogging

If I have to name two out of a gazillion of a blogger’s worst enemies, it would be, 1) crappy internet connection, and 2) Spam.

Okay, I’m not exactly a blogger, seeing how I abandoned my own blog like this (geez, months of no updates). Let’s just assume I am a (borderline) blogger, for the sake of simplicity.

So, how does a crappy internet connection harm you then? Well, if you are like me, and you care for everything that comes out from your keyboard, you’d clog your tube (read: use the internet extensively), for research and the wellness of your post (even if you are sure that most of them will end up in the Drafts section anyway, uncompleted, or just stopped being an interesting topic anymore).

Research.

Let’s say that you are writing about the ways a baseball cap would make you look cool in every occasion, you would want to search for images of those aforementioned caps to put in your post. Maybe one or more images of people actually using them and looks cool. In a situation like this, a crappy internet connection would surely put your anger to the same level with Jack Bauer.

Additionally, you’d want your post to be enjoyable to read too. The experts have said that you should have valid opinions and a correct and readable writing, in order to succeed at your endeavors in getting your points accross. That’s where the browsing on the web comes in. Fact-finding. Read about it beforehand to know what you are talking about. Arrange your points so that they are easy to understand.

Questions like, “Is this true?”, “What about that?”, “Could they understand?” are some of the questions you have to constantly ask yourself, whenever you feel like telling someone something.

Okay, I’ll admit it, it’s damn hard to write a good post. Heck, even this post are not remotely useful. There are little facts in here, not to mention the ultra-subjective sentences and opinions that are coming from the unicorn’s land. But at least, yes, at least, try to use your language right. Try to check for typos and the meaning of words and the correct way to use them in a sentence before publishing it. Wear a helmet before presenting yourself to a skyscraper construction site.

All of this, off course, have the drawback of throwing you further from ever posting a single article on the web. Every now and later you should not think too far and just post whatever crap you are writing, regardless of amount of time you spent preparing it, just for the sake of getting something up. The writers call this a “Writer’s block”, and a good way to overcome it is to “stop thinking and start writing”. The same thing applies to artists, software engineers, and many more professions as well.

Enough of that, let’s move on to spam. It comes with publishing your blog to the web, just like Nunu following after the Teletubbies, to clean up every mess they might have made, but instead of cleaning, the spam comments are littering your blog.

I’ve found that spam comments are getting more and more creative than usual. They usually stuff their comments with links and words regarding money and stuff enlargement etc. until Akismet sniped out every one of them. But now, even you (a human, right?) will have a hard time distinguishing which one is a real comment from a reader (yay!) and which are from faceless spambots. One of my favorite was:

“Hi, this is a good post. But I think that you are missing out something. See my response here: http://www.a-seemingly-innocent-url-that-you-will-possibly-click.org”. Alex from the neighboring site has his own problem with this kind of spam. Good luck with that, Alex.

Currently I don’t have any problem with spam on this blog here. I’m thinking maybe:
1. Because of my uncommon choice of URL. I decided to follow xkcd‘s style here, being the uncreative stooge that I am. I assume that most of the spambots targets domain.tld/blog/ or blog.domain.tld/
2. Because of the highly unusual amount of traffic. (Yes, it’s that low)
Anyway, here I am, throwing out assumptions again after I’ve talk about the importance of research.

What did I do?

“So, what do you do?”

That, dear good reader. is somewhat an obligatory question whenever a person is chatting with his/her long-time-no-see friend.

When I am asked that by people, my usual reply is:

“I work as a programmer, or to be specific, web developer.”

“Oh, so you are a web developer? ¬†Where is it?” usually follows after that. But, for non web-workers, which 90% of my friends or family are, that will pretty much threw them off a great distance, leaving only blank faces and mouths saying, “What is that?”.

Okay, so, that, apparently, is not helpful and nothing but a waste of breath. Being driven by the mindset to keep things practical (and being a lazy that I am), I decided that I should came up with something.. that is easier to understand.

“So, I make websites.”
Sums it up pretty good. Most of them understand now, that I make “websites”, those pages with text and images filling up their screen when they surfed the Web. The problem comes after this, which is to make them understand, that I didn’t actually do the design and is just focusing on the development side. Which is the engines, or the stuff under the hood, or the kitchen, or the electricity and plumbing system or whatever. Chances are slim that I have to go into great length to explain about the details, since most of them didn’t ask, or it probably didn’t even cross their mind.

There are still some, albeit very small, number of people that has never heard about a website (probably know but didn’t familiar with the term?), so most of the response to this are, “Oh, I see.” or “Wow”, which is nice, because it means that they’ve got it.

Along the line of this, I’ve heard something as disconcerting as, “So, you kind of, created the Facebook and Wikipedia? Awesome.” once. That’s like saying to a police, “So, after enhancing their images from the surveillance camera, you locate and use those cool auto-rifles to shoot the bad guys, eh? Awesome”.

“I work in front of a computer”
Correct, because I work in front of a monitor all day. But then so are graphic designers, copywriters, illustrators, animators, cashiers, secretaries. This often ends up with them asking more about the details and me switching to another response. Easy to understand, but still impractical (the vagueness).

“I write web applications and sometimes also server-side scripts to support Flash-based websites”
Bam. End of story. Change of topic ensues.
