Damien Katz and the CouchDB development team are proud to announce:
CouchDB version 0.7.0 is now available.
This release is a major milestone in the project’s history.
Key features include:
Thank you Frankfurt, what an evening! Thanks a lot for the invitation and my trip-sponsors. In fact the people and venue were so nice, I am seriously looking for an excuse to go again.
For housekeeping, here are the promised slides (PDF, 0.662 MB, sans images). In Some Context I wrote:
I rarely see the point of posting the slides of a presentation for people who didn’t see the original presentation. Yet, this is often requested. I don’t have a problem with posting my […] slides […], but they are of little value without context and I do have a problem with posting things of little value, so here’s the context.
And it goes on to comment the slides I used for my CouchDB presentation in Zurich. The new slides are …

"I heard it is faster if I use server side prepared
statements" - Many people
Possibly - but it's not necessarily the silver bullet it's
described as.
A little bit of background:
A server side prepared statement allows you to first prepare a
query on the server side, without actually specifying the values
at all.
INSERT INTO users (username, email, password) VALUES (?, ?, ?);
This is step 1. From here, the application now only needs to send
the individual values to the server next time, and not repeat the
entire query (step 2).
The values will also be sent using the binary protocol so they do
not need to be escaped in the same way they would in a regular
query. There is no SQL parsing overhead, and certain steps of the
execution plan have already been figured out.
Sounds great, why this doesn't always convert to being
faster? …
Installing software on the Mac is usually a no-brainer: You get a ZIP archive or disk image that gets uncompressed or mounted for you. What is left for you is to move whatever application to your Applications folder. Done.
In case of a disk image, developers often go so far to include a reference to your Applications folder on the disk image itself. So all you have to do is to drag an icon onto another one less than 200 pixels away. This works so nicely on the Mac (the advantages of a controlled environment) because in the majority of cases, it is at /Applications on your filesystem.
To make that even easier, developers usually put nice background images onto those disk images to illustrate (with an arrow for example), what the user has to do. Skype, among others, nail this experience. (I’m not talking about the ZIP-only approach here). They have, on their download page, a step-by-step guide accompanied …

A while back, I had talked about the issues I had with my
EVDO express card purchase and my macbook pro,
a lot of you asked me to sum up my experiences with the card, and
to comment on whether the speeds are worthy of being a primary
connection or not, so here’s my answer.
Definitely, maybe.
I know, such definitive answers make me sound like a politician
don’t they? Well.. politicians would probably skirt the question
completely..
Here are my experiences with the Sprint USB card since late June
2007.
EVDO/3G data cards and plans are the most liberating technology ever sold. Seriously.
I am no longer confined to the house. I am no longer confined to
starbucks and other places with stable wifi (Panera)
(usually).
I can work, or play anywhere …
The kind folks at the PHP Usergroup Frankfurt invited me to talk about CouchDB. We meet on November 8th between 19:30 and 20:00 at the Brotfabrik in Frankfurt. If you are in the area and like to hear about CouchDB, feel free to join us.
I will be presenting CouchDB’s core concepts, its recent improvements and the programming interface to give you an overview. Building on that, I will explain how to architect CouchDB applications and show best practices for writing them not forgetting how to do all that from PHP.
In case you forgot:
CouchDB is designed for highly concurrent, distributed and fault tolerant systems. The core principles for scaling database applications are the foundation of CouchDB’s feature set. It supports on- and offline replication, data …
[Read more]Apple announced, as expected, a release date for Mac OS 10.5 Leopard. The date is October 26th, 2007 in case you missed it. Since everyone on the internet is a guru, and therefore, so am I, I will give you plebes reasons to upgrade to Leopard. But, first let me qualify myself worthy of such preachery (gurus can make up words).
I’m going to assume that the build shipped to us ADC members, has
been updated and will not be the build that will be released to
the masses, there are still bugs in my release, but it’s leaps
and bounds ahead of the August release, and very close to
stable.

[Read more]I presented at ZendCon this week on performance MySQL coding techniques. The session was packed, and I got a bunch of great questions from the audience. I figured I would post the slide deck in both ODP and PDF formats. Feel free to download!
