OnLamp.com: Advanced MySQL Replication Techniques

As I run this server on a MySQL powered solution (a Hibernate-based web-app running on JBoss4 on Linux), I’ve wondered occasionally what it would take to introduce fault tolerance at the database level in case of server failure.

OnLamp.com have an article by Giuseppe Maxia called “Advanced MySQL Replication Techniques” that shows what is involved to set up replication between multiple database server instances to introduce high availability of a MySQL database.

Barrier to entry for new PS3 – $499 and $599 versions?

Sony annouced the exact launch dates, configurations and prices yesterday for the much awaited PS3, with it’s 7 core processor, the Cell.

At $499 for the 20GB version and $599 for the 60GB version, one can only think that this is priced way too high for the ‘casual gamer’ and average consumer – you are not going to get the average family pass the electronics store and pick one up without some serious consideration first. However, since Sony bets on a 10 year lifespan for their gaming consoles, is this configuration well placed to last the next 10 years? Yes, probably.

Even at these prices Sony is expected to be taking a serious loss per unit sold, at a cost to manufacture estimated at approx $800 per unit.

The launch date for the new PS3 will be Nov 1 in Japan, followed by Nov 17 in North America.

According to Joystiq, here’s the difference in features in terms of the $100 difference:

  • 20GB base vs. 60GB

  • You lose HDMI output
  • You lose MemoryStick / SD / CompactFlash slots
  • You lose 802.11 b/g wireless

    This looks like a substantial difference, so it’s not just the HD upgraded size.
