Databases are used by many different disciplines, from your DBA to your Developer, right down to the End User. They can also be viewed from many different perspectives…

DBA’s are usually interested in the server configuration, index usage etc. Developers however are often concerned with retrieval methods, datatypes and occasionally stored procedures. One thing is for sure, your database if used effectively will be changing frequently, and with so many people accessing your database do you know what the last change was? Would you know if someone added an index to a table? (would you care… )

Revision Control is often used to track changes to source code and other documents, so why not your …

I was thinking of this and could not figure it out or maybe I am just confused... Hehehe.

If MySQL is lagging behind the master (7,000 secs.), would it be caused by the I/O thread being slow or by the SQL thread (of course, this is assuming that I only have these two options to choose from)? If it is the I/O thread, what should I be looking for?

I've always assumed that the I/O thread would not cause a huge replication delay as it is just reading the binary logs from the master. So, if the Master_Log_File and Relay_Master_Log_File are the same and the Exec_Master_Log_Pos and Read_Master_Log_Pos are the same too, then I can assume that the replication delay is not based on the I/O thread, right?

And does anyone know how to compute the Seconds_Behind_Master???

The session has been recorded. The webex file and the webinar are available here.

Here is the Q&A session, with more detailed answers.

Q from Tomasz: You said memcached is integrated with, among others, MySQL. Did you mean integration by e.g. php or direct, automatic integration?
A: Memcached API are available for many enviroments, such as Php, Perl, C/C++, Rails etc. With MySQL, you can use UDF functions or a storage engine. Both are community projects.

Q from Juan: memcached: Facts data size up to 1MB? What size, i dont understand!
A: It's the size of an item associated to a key. When you store an element (item) into memcached, the size of the key is max 250 bytes and the item is max 1MByte.

Q from Frederik: Do memcached save data in RAM or disk?
A: It is RAM …

On January this year, I decided it was time to get a new computer. May be catch a boxing day deal. After choosing a nice quad core with 4 GB of RAM, I realize one 'small' problem with this Dell: it comes with Vista. Any other options for the OS? Nope, it's Vista or Vista.

If, at the time, I had not had previous experience with Vista, I would've been happy to get it. But another box I had bought for the living room came with Vista, so I knew it.

And this is what was in my mind: Vista can make my new Quad core run like an old XT 8088. I won't even notice that I have 4 GB of RAM, Vista will swallow it whole with nothing left for me to run vi. It is big, and it is slow.

Next is the stability. I saw Vista crashing too often. The file explorer at least once a day.

So, as I was looking at the checkout screen of the Dell site, instead of having a nice picture of productivity and speed, I could see only dark Vista …

So I got a new laptop, a Zepto Znote 6024W.

I got it with 2GB of RAM, a 7200RPM 120GB harddisk, 1440x900 screen, 2.4GHz Intel Core Duo CPU, and Intel Pro/Wireless 4965AGN.

First overall impressions are quite good. The good stuff:

• Everything seems to work out-of-the-box with Ubuntu Hardy.
• You can customize the configuration when you order it, so you don't have to pay (money and power wise) for stuff you do not need. This includes the Operating System, so no Microsoft tax (I would probably have gotten a Thinkpad if I could have found a place to buy it without Windows).
• The machine feels fairly small, and not too heavy.
• The machine feels generally quite fast.
• It has 4 USB ports (my old one had only two).
• The mains adapter is two-legged with the cord on top, so should fit everywhere (for some reason it is quite common to get three-legged …

Phew....People ask what the first week at Google is like... I cannot find one word which can describe it but I'll try throwing together a few adjectives:Exciting. Exhausting. Fun. Delicious.The reason for the first adjective is obvious. The second adjective - simply because its like going back to school with stuff to learn. The third - I met a lot of interesting people and they are all fun to

In just a few minutes, I will be leaving for Graphing Social Patterns East, a conference by Oreilly. Dave McClure of 500 Hats is the conference chair. I plan to meet old friends and make new ones. It should be a lot of fun. More about Graphing Social Patterns.

Normally, I try to avoid reading business books. I especially avoid those promoting the secret sauce to building great companies. I figure the folks who actually do the building often tend to be too busy working, or otherwise enjoying the fruits of their labors instead of writing books. Plus, there are no shortcuts into building enduring companies, regardless of what we might see occasionally in the tech sector.

A few months ago I found myself at a bookstore and ended up buying a book called Good to Great. It’s actually a decent book, particularly because it is based on actual research.

One of the central elements of the book deals with the task of making sure you have the right team in place (”Get the right people on the bus, the wrong people off the bus”). We’ve …
