restoring a single table from mysqldump

Following Restore one table from an ALL database dump and Restore a Single Table From mysqldump, I would like to add my own thoughts and comments on the subject.I also wish to note performance issues with the two suggested solutions, and offer improvements.

CSS Font Size Conversion Chart

For those of you who are still using pixels, it’s about time you made the switch to ems or points.  It allows users who have a hard time reading small type to enlarge the font.  Here is a little trick that will help you so you don’t have to remember the chart above.

body { font-size: 62.5% }

This will make 1.0 em the same as 10px.  So if you wanted 12 px. would be 1.2em, nice and easy.  Hopefully this will help you out, I know I use it all the time.  Enjoy.

Mobile Usability

Mobile use is one of the biggest challenges now facing many websites. Its also important for some intranets, particularly in companies with many traveling employees.

via Mobile Usability Jakob Nielsens Alertbox.

The challenge has been around since the PalmPilot + application specific tools.

I suspect the success rate for doing “phone” tasks or “address book” tasks is much higher than the “web” tasks.

A custom application (which is all that a “Mobile Site” is, really) is going to provide a better experience.

Simple example? Google Maps – can’t use it on a “mobile” browser. The custom application for my phone works quite well.

How to Kill Your Book Sales

How to Kill Your Book Sales | Carsten’s Random Ramblings

I believe the first time I heard about using publically-available Flightstats database for teaching databases was when Jeremy Cole suggested using it in the MySQL training program to demonstrate working with large data sets. I’m not sure it ever got used for that purpose, but others have followed up on the same idea in other contexts. The Flightstats database contains 10 years of US airline flight information, consisting of several Gigabytes of data in a fairly wide table, and so is excellent for talking about optimizations and search strategies.

The article is about book sales, but it really talks about sample databases for demonstration purposes.

For a given value of natively

For a given value of “natively”… | Carsten’s Random Ramblings

A quick (but somewhat simplistic) way to test performance of different methodologies is to turn off the query cache and use the BENCHMARK function. BENCHMARK loops over an expression a given number of times, and always returns 0, which is in itself quite uninteresting. But we can then look at the execution time to see how long things took.

I love it when the verbose expressions turn out wicked fast.

Should You Use An ETL Tool?

IntelligentEnterprise : Kimball University: Should You Use An ETL Tool?

You can still hand-code an extract, transform and load system, but in most cases the self-documentation, structured development path and extensibility of an ETL tool is well worth the cost. Here’s a close look at the pros and cons of buying rather than building.
