This is about me getting a substantial amount of grey hair over the past couple of days, trying to hunt down a setting that would cause the current version of Xcode 4 to build my iOS projects to an unexpected, but not unfamiliar, taken over from Xcode 3, location, but not presenting any obvious way to revert that.


A little history
In Xcode3 you could use the preferences dialog to configure custom build output folders. This was necessary when you wanted to organize a somewhat more complex software into several cross-referencing Xcode projects and at the same time retain some sanity when linking and packaging it. Clint Harris Tutorial on shared libraries describes it in more detail.

The preferences dialog looked like this (image copied from Clint’s site, because I didn’t have any Xcode3 installation …

Our continuous investment and advancement has culminated in releasing SchoonerSQL 5.1.1.
This is built on SchoonerSQL 5.1 that includes all the exciting features e.g. auto async replication failover for WAN or LAN, intra-schema parallel replication appliers for WAN or LAN, customized alerts and fast sync recovery.
Highlights below-

• Improved async parallel applier performance(more than 4x throughput improvement compared to MySQL 5.5)
• Online upgrades
• Improved logging and statistics for diagnostics and trouble-shooting
• Customer requested enhancements and stability fixes

Just because this took a little longer than I expected, here’s a quick howto for setting up an anonymous FTP drop-off on Oracle Linux, which I use as a simple way to transfer files out of my Virtual Machines.

Install vsftpd

$ sudo yum -y install vsftpd

Configure iptables

As FTP is a more complicated protocol than most, there is a special netfilter module required in order to correctly keep track of connections.

# You will perhaps want to change the insert number here.
$ sudo iptables -I INPUT 4 -m state --state NEW -p tcp --dport 21 -j ACCEPT
$ sudo /etc/init.d/iptables save

Add nf_conntrack_ftp to IPTABLES_MODULES

$ sudo vi /etc/sysconfig/iptables-config

Then load the module rather than reboot

$ sudo modprobe nf_conntrack_ftp

Create /incoming

I suppose the true birthdate could be debated, but from the *Community* perspective, it can be either the 14 or 11 year birthdate for MySQL!

*Unless* of course you are Monty or David, or one of the internal testers/users, for which May 95 may hold slightly more significance

14 Years ago: The Windows [alpha] was released January 8, 1998.

11 Years ago: The first GA version of 3.23 was released in January 2001

http://en.wikipedia.org/wiki/MySQL#Product_history

Note Monty and David first began working on MySQL in 1994, and the first internal release occurred on May 23, 1995. But, since that was all internal, January works for me.

Happy Birthday MySQL!

Hi again

It's time to announce the next Helsinki MySQL User Group which is on February 8 at 18:00. Venue is Solinor's meeting and sauna facilities in North Haaga: http://www.meetup.com/The-Helsinki-MySQL-User-Group/events/42163422/

By popular request, Monty will be sharing news about MariaDB, after which there is the usual food, beverages, sauna and socializing.

The organizers would really appreciate it if you could RSVP at the meetup request above. Last time the place was already packed and now with this kind of superstar speaker the hosts want to make sure they book an appropriate room and enough food. (Seems there's already 20+ going!)

See you there!

This post is just to show how easy it is to upgrade or migrate from MySQL to MariaDB.

I should begin by stating this article is geared more towards MySQL 5.1 and prior, as MySQL 5.5 users will likely want to wait until MariaDB 5.5 is available (which I believe will be in the near future).

As you may or may not know, there are actually 3 flavors of MariaDB currently: 5.1, 5.2, and 5.3.

All three are based off of the 5.1 MySQL code base, just 5.2 and 5.3 have further improvements over 5.1. So, that’s why I say this upgrade is “easy” and there’s no need to be afraid, especially for 5.1 users. But even if you were a 5.0 user, the upgrade to MySQL 5.1 compared to MariaDB 5.1 would not be any different. So, why not give it a go?

You’ll have all of the benefits from using MySQL, but also all of the added improvements from MariaDB and XtraDB+.

I like the fact you can “ease” into it. For instance, …
