Best Tech Videos 2.0 has been released!
9 Jul2007

So, we did it! New Best Tech Videos site version has been released today. Of course, it could have some issues, and we are really looking forward for your feedback on our support forums.

Let’s review main improvements we’ve made here:

  • First of all, I want to mention our first step to socialization of the BTV – all our users could signup now and get their own lists of favorited, commented and voted videos and much more – they could have their own personal RSS feeds.
  • Next cool thing we’ve prepared for you is user-generated content! You can find some great videos on the Net and share them with fellow BTV readers. At this moment our posting system works in pre-moderated mode to keep really high level of videos we post here, but later we want to delegate moderation to our most active members.
  • As I mentioned before – we have our own video rating system. All our users could vote for videos they like and then we’ll let users to decide, what videos they would like to watch based on these votes.

So, these are just small part (but most valuable) of our ideas. If you want to have a look at all of them, just sign up and start using the service – you gonna like it, we’re sure!

Thanks to all our readers, without your help this release would not happen!


MySQL Proxy Released
30 Jun2007

Few month ago I heard about some initial work on MySQL Proxy software by Jan Kneschke and I thought about implementing some type of MySQL Replication Aggregator based on this software. The idea was to create some piece of software which could get many replication streams, merge them and feed to some mysql slave. This software could be used for backup purposes and many other interesting things. But back then mysqlproxy distribution has been suspended (afaik, by MySQL AB because of some legal issues).

And at last, today MySQL Proxy project has been released to public and it became much more flexible so I think we need to take a look at it and try to implement such replication aggregator patches for it.

25 May2007

Thanks to MySQL community members we’ve got really great collection of media files from the recent mysqluc. Thanks to Seeri for all that work he’s done to collect everything in one place so we could watch/listen/read information from this great event.

So, if you did not attended mysqluc07, then you definitely should visit Technocation page, dedicated to this conference.

P.S. I’m going to post links to these videos and descriptions for the sessions on the Best Tech Videos soon, so If you are not sure to watch some video or not, just wait while I’m merging these links with information from mysqluc site.


MMM Release 1.0-pre4
16 May2007

New alpha release 1.0-pre4 of the MySQL Master-Master Replication Manager. This release has lots of major fixes and I’m glad to announce first sponsored port of mmm to non-linux platform – it has been ported to Solaris 10. So, here are our changes in this version:

  • Real checks timeouts – I’ve found and fixed lots of problems in checks timeout code and now if you specified in your mmm_mon.conf, that some check should timeout in 5 sec, it would timeout correctly on all supported platforms.
  • External third-party tools using – On all supported non-linux platforms mmm will use system binaries for fping and arp_ping so porting to another platforms would be much easier.
  • Agent notifications fix – Now we don’t try to notify dead agents about cluster changes and additionally we have 10 sec timeout on notification sends to prevent monitoring from lagging on network connection timeouts.
  • Bundled fping and send_arp – We have both used third-party tools used in mmm bundled in our distribution as separate build trees (you could find and build/install them from contrib directory).
  • Flexible perl binary location – We’re using “#!/usr/bin/env perl” as shebang line in our perl scripts so you can use any perl interpreter just by placing it earlier in your PATH variable.

Notice: If you’ll try to install this version, try to run bin/sys/fping and bin/sys/send_arp on your server before installation. If you’ll notice any errors, feel free to build binaries for your platform using contrib/* sources (you’ll need gcc and libnet installed).

So, as you can see, mmm development goes forward and we’re fixing some problems trying to make this software mature. If you want to help us, you can send your comments to mmm-devel mailing list, post your bug reports to our bug tracking or sponsor any changes you need 😉
