How to Install Tuxonice in Ubuntu

How to Install Tuxonice in Ubuntu | Ubuntu Geek

"TuxOnIce is most easily described as the Linux equivalentof Windows' hibernate functionality, but better. It saves the contents of memory to disk and powers down. When the computer is started up again, it reloads the contents and the user can continue from where they left off. No documents need to be reloaded or applications reopened and the process is much faster than a normal shutdown and start up." – tuxonice.net

Tuxonice is an alternative way to hibernate your machine than the standard ubuntu power manager way. It generally claims to be more configurable and flexible than the standard method, with faster hibernate and resume times.

How to Fix a Running Toilet

How to Fix a Running Toilet - wikiHow

Replace the flapper. If the toilet stops filling and then starts again intermittently, you have a slow leak. Try this to be certain. Place a dye tablet or a few drops of food coloring in the tank. Your local hardware store may have free dye tablets for this purpose. If, after an hour or two without flushing, you see this dye in the bowl, you have a slow leak, a small amount of water running into the bowl. The most common cause of slow leaks is a leaky flapper. Over time, this inexpensive rubber part decays, or minerals build up on it. Cleaning may work to remove mineral buildup, but it's usually best just to replace the whole part. There are a few standard kinds. Take your old one with you to the hardware store if you want the comparison to get the right size.

Close this valve by turning it clockwise, as you would a faucet.

To perform the replacement, simply close the valve sticking out of the wall under your toilet tank.
Flush the toilet. If the valve is completely closed, the tank will not refill and you will not hear water running after the tank empties.
Pop the old flapper off its hinges, disconnect it from the chain, and pop the new one into place.
Run a finger carefully around the rim where the flapper seats. Remove any uneven buildup of minerals that might cause a leak.
Don't forget to open the valve all the way when you're ready for water again.
Try flushing a few times to make sure the chain is the right length for the new flapper. It should open when you push the handle and then drop closed all the way when the tank empties. You may have to trim and adjust the chain by trial and error. Also, make sure that the flapper aligns properly with the opening.

Sphinx - a free open-source SQL full-text search engine

Sphinx: Search Outside the Box | Linux Magazine

For many years, the only easy way to add decent search capability to a MySQL-backed web site was to use its full-text index support. It was fast, efficient, and reasonably configurable. But as more and more sites began to deal with larger datasets and moved from MyISAM to InnoDB, they found that it was harder to support their search needs. InnoDB does not provide full-text indexing, so that often meant keeping around a set of slaves that still ran MyISAM for the sole purpose of handling full-text search requests.

Sphinx is a powerful, free full-text search engine that works extremely well with MySQL.

Sphinx was a project born out of the need for something better than MySQL’s full-text search for sites already using MySQL. It’s available both as a MySQL storage engine and as a stand-alone daemon. There are pros and cons to both deployment methods, but I’m going to focus mainly on the stand-alone daemon for this article. Not only is it what I’m most familiar with, I believe it to be far more powerful and flexible.

New Online Tool Extracts Vocabulary

Thinkmap Visual Thesaurus has launched a new tool called VocabGrabber (http://vocabgrabber.com) that helps teachers and students target the key vocabulary from a text within seconds. VocabGrabber extracts words from any document and demonstrates how those words are used in context. It's intended for language arts teachers, students of English at all levels of proficiency, or anyone who wants fresh insights into how language works.

VocabGrabber compares how often words appear in the text with the frequency of these words in standard written English overall. Grabbing the vocabulary from the United States Bill of Rights, for instance, highlights significant legal terms like probable cause and cruel and unusual punishment. Grabbing the opening of the Charles Dickens classic Oliver Twist, meanwhile, will quickly zero in on words like workhouse, gruel, and pauper.

Teachers and students can use VocabGrabber to highlight vocabulary specific to a subject area -- focusing on just the science-related words from the latest news coverage about swine flu, or just the artistic and literary terms in an article about the history of poetry. Additionally, VocabGrabber can be used to select only those words that are typically taught in vocabulary instruction, useful for students preparing for local standardized tests, or national tests like the SAT, ACT, GMAT, GRE, and TOEFL.

How do I learn Flex?

Sean Moore - Flex Developer, AIR Developer, ActionScript Programmer

The world of Flex development is pretty big and it's expanding all the time. There are many types of applications that can be built with Flex from dashboards to widgets, media playback utilities to Enterprise RIAs and don't forget interactive kiosks and Internet aware desktop applications. One of the most common questions that I get asked is: How/Where do I learn Flex? I think one of the keys to mastery is a successful learning path. I also think that a solid foundation goes a long way. We've all heard the phrase: "crawl, walk, run…"

Here are some resources that helped me learn Flex. They are organized in a somewhat sequential fashion.

Beginner

Lynda.com

O'Reilly Programming Flex 3

Adobe.com

DClick Adobe Flex Coding Guidelines

CFlex, Community Flex

Using ASDoc

Intermeditate

AtTest (practice exam engine for Adobe Flex Developer Certification)
