Facebook loves  

Just recently, Facebook has messed up all instances of a unicode character "à" (latin small letter A with grave, code: U+00E0). My biggest guess is they (Facebook Team) ran into a UI problem so they decide to make dirty str_replace before sending output for both the main site and mobile site. I said it's just some kind of search and replace for the output because getting posts directly with Facebook API works just fine


The replacement originally is "&nbsp;" but for some reasons, it gets displayed as "?nbsp;". FYI, &nbsp; is a html entity which means "no break space". What the hell is it? Normally, all browser will ignore multiple spaces placed together. This is used as a trick to bypass character count in replying post: just type an emoticon (":D", 2 characters), hold the space bar for a few seconds to generate around 20 spaces, type anything else (a period is enough). The post will be displayed with only 1 space between the emoticon and the period. Note that if you don't type the period, it's high chance that the post will be trimed (remove spaces at the beginning and the end) so your post will failed the character count validation. Back to &nbsp;, using it just like space but browser will keep them as it. You put 20 of them, they will be displayed all. Some people even used &nbsp; to indent their stuffs! Actually, it's sometime useful to use &nbsp;, for example when you have to leave an empty <div>
or <td>, you should place a &nbsp; inside to make the XHTML document validated. See the demonstration below: they both have 20 spaces between the emoticon and the period.

  • Using spaces: ":D ."
  • Using &nbsp;: ":D                    ."

Anyway, a bug has been filed but I think Vietnamese users will have to wait. Stay calm, everybody.

  2. Wow. You should definitely vote for the bug. If you haven't had an account, it will take you 1 minute to get one. Vote it so they MAYBE soon notice the problem and fix it.

    PS: Nice to meet you.

IMAP module for PHP in Mac OS X Mountain Lion

So here it comes again. I have recently upgraded to Mountain Lion and for whatever reason, Apple decided to nuked all my previous PHP (among other things) configurations so I have to setup IMAP in PHP again. A simple Google search may point you to this post with detailed instruction for Lion however, some steps have been changed a bit...

Step 1: Install prerequisites You may choose to download Xcode (FREE) from the App Store then go to menu Xcode > menu item Preferences > tab Downloads, select to install Command Line Tools OR you can go to Apple Developer to get it, you may need to login.

Step 2: Compile IMAP Get the IMAP source code from University of Washington website. Please do me a favor and check that website for the latest version, it's good practice. If you that lazy, try to click the "y" to get direct link to 2007f version.

Extract the package and open the Terminal to the new directory before executing these command:

make osx EXTRACFLAGS="-arch i386 -a…

OAuth with Google, Twitter and... Facebook!

This is sick!

Just a few days ago, I ran into OAuth as I want to get my GMail feed based on Google Data API. I succeeded. With a little help of an OAuth open source (here, available in several programming languages).

Then I remember that I once heard that Twitter also uses OAuth as an authentication option so I turned into Twitter and had a good read. Finally, I found out that they are basically the same (hehe, it's obvious since OAuth 1.0 is a worldwide standard). I had an idea of writing a universal class which can handle both Google and Twitter OAuth functionalities. It's not too hard. I took most of the idea from the PHP example (here, PHP only). I also made a small script which accepts URI to send and intercept response from Google & Twitter servers.

At that moment, I was so excited with all the ideas but actually it has no real world benefit so I just left it there... Until today, in the F8 (says "fate") conference of Facebook, I was stunned finding out tha…

What the Hell Is Going on in Vietnam?

I have just read this: What the Hell Is Going on in Indonesia via TechCrunch. The author (Sarah Lacy, one of my favourite) took her chance in Indonesia to find out why there is such a great growth in Internet usage in that South East Asia country. It was a good read.

There are some interesting parts like

I grilled them on some basic questions to bring you a Web-in-Indonesia primer. But before we get to those, here’s what impressed me the most about this small-but-tightly-knit community: It’s incredibly collegial. Plenty of research has shown that the biggest reason Silicon Valley beat Boston as a venture capital and startup hot spot was because culturally it was open, trading employees, funding, mentorship and ideas among competitors. It’s not uncommon to see Web competitors in the Valley having dinner together and generally discussing business challenges, before they go back to the office for some late night coding to bury one another in the market.I laughed so hard reading this!  But…
