The country of Israel is broken up into 6 administrative districts with 15 sub-districts and 50 natural regions. It is my understanding according to the Isarael Central Bureau Statistics that the sub-districts are similar to what we call Provinces/States in North America and the natural regions are similar to municipalities/counties.

I’m not fully understanding the West Bank, Gaza Strip, Golan Heights and East Jerusalem. Are they territories of Israel or a part of another country? How would one reference where you lived if you were lived in one of these regions (ie. West Bank, Isarel)?

This knowledge maybe helpful for those that need to reference contact information or allow clients to select their country and province/state/district.

• During yesterday's meetup in New York, an attendee asked advice about broken replication in a circular scheme, and I suggested reading all the …

We'll talk about MySQL Proxy, and anything else that looks suitable, depending on the crowd's requests.
Thanks to Greg Haase for organizing.

For the last few months, I've been working feverishly to get the web2.0kit open-sourced. What is the web2.0kit, you ask ? We introduced this at our session at the Velocity conference. The web2.0kit is a reference architecture to help anyone running a web application evaluate the suitability, functionality and performance of various web technologies.

Most web2.0 sites today use open source languages and frameworks such as PHP, Ruby on Rails and Java EE to develop their applications. Deployments of these applications also use popular open source servers such as Apache httpd, MySQL, memcached and glassfish. Many other servers/technologies such as lighttpd, nginx, mogileFS, mongrel, thin, JRuby are also gaining popularity. To help understand the differences …

G2One acquisition adds SpringSource to the list of vendors endorsing Groovy, but relying on a support business model for Groovy may not be the best path forward. READ MORE

As you may have recently seen there are some articles about scaling MySQL one 256-way system.

I though wow did they really make it work, considering how many bottlenecks remain in MySQL.

What article really tells us ?

First the number 256 - this is not number of Cores... this is number of hardware threads which is not exactly the same thing. Each T2 Plus CPU has 8 cores, which with 8 threads each giving 64 threads per chip or 256 threads all together.

Now what is about MySQL scaling to use these 32 cores with 256 threads ? Especially with the goal of "Do it with minimal tuning i.e as close as possible as out-of-the-box" ? Do we simply start MySQL server and change couple of defaults to make it work ?

No! To get really …
