Eclipse 3.7 M5 New and Noteworthy

Here is the new and noteworthy list for the milestone 5 of Eclipse 3.7 (aka Indigo).

guava-r08 is here!

Last night, Kevin released the 8th version of Google Guava libraries. For me personally, nothing so exciting in this release. Just nice to have some bugs fixed and some new methods and classes. MinMaxPriorityQueue could be interesting, but I don’t have scenario where to use it right now.

Enjoy it while it lasts!

Google Cloud Print?

Will it be a better solution than AirPrint?

By connecting your printer with the Google Cloud you will be able to print to your printer from any computer or smart phone, regardless of where you are. Just activate the Google Cloud Print connector in Google Chrome and your printer will automatically be available to you from Google Cloud Print enabled web and mobile apps.

Wolfram Alpha API

Now is for all to use. I hope people will build sophisticated application using the API. Java binding is also available!

By the way, DuckDuckGo also uses the API.

DuckDuckGo

While Google is obviously the only search engine for many people, it’s been lately spoiled by black SEO practice which causes a lot of spams in its search result.

Here comes a new search engine, which promises to filter spam websites and promises not to track its visitors. While it’s certainly not close enough to any major search engines out there, it has great promise and it is for us to see the future…

Removing vertical scrollbar from SyntaxHighlighter 3

Published on January 17, 2011 in Uncategorized. 0 Comments

An annoying bug in the new version of SyntaxHighlighter 3 shows vertical scrollbar on every code snippet.

To fix this, SSH to your hosting and change the code under syntaxhighlighter/syntaxhighlighter3/styles/shCore.css and change:

.syntaxhighlighter {
  ...
  overflow: auto !important;
  ...
}

to:

.syntaxhighlighter {
  ...
  overflow: hidden !important;
  ...
}

Proof: Did you see vertical scrollbar on my snippet?

Code coverage goal: 80% and no less!

But it is nice to see green overall on your code coverage reports, isn’t it?

How you compare the old Google Docs and the new one?

Here is the old:

Here is the new:

I like the new one much better.

2000! Yippi!

I can now edit a post on StackOverflow.
