This poser comes from Diego Madina.
Using a fairly recent MySQL 5.0 distribution, we see that…
mysql> SELECT 1.1E0, 2.2E0, 3.3E0; +-------+-------+-------+ | 1.1E0 | 2.2E0 | 3.3E0 | +-------+-------+-------+ | 1.1 | 2.2 | 3.3 | +-------+-------+-------+ 1 row in set (0.00 sec)
and…
mysql> select 1.1+2.2=3.3; +-------------+ | 1.1+2.2=3.3 | +-------------+ | 1 | +-------------+ 1 row in set (0.00 sec)
But…
mysql> select 1.1E0+2.2E0=3.3E0; +-------------------+ | 1.1E0+2.2E0=3.3E0 | +-------------------+ | 0 | +-------------------+ 1 row in set (0.00 sec)

[Read more]ASM is definitely one of the coolest technologies inside the Oracle Database. On the other hand, the ability of the storage arrays to provide a read/write access to a copy or a “snapshot” of its content is something we can easily leverage as an Oracle DBA. For a couple of weeks, I wanted to [...]
Well its been a while since I started this, so I thought it was about time to put some of this to rest. I have been beating up the Mtron disks for several weeks. During that time I had a couple of really odd outages, a lot of head scratching, and my fair share of number crunching. I have been talking with Kevin Burton a lot the last few weeks, we have compared and shared information on the optimal configuration for the current generation of ssd drives. I have held back a large number of my benchmarks because i want to get a complete picture. I want to evaluate the drives & the MFT software while minimizing any self induced mishaps. I have ran and reran tests over and over again, at last count I had run over 280 …
[Read more]Today we announced a significant enhancement to our Zmanda Recovery Manager (ZRM) for MySQL product. Here are major highlights of this new version (2.1):
End-to-end support for Solaris: We have had increasing number of requests from customers for supporting Solaris. While we always protected MySQL databases running on Solaris, we needed customers to run the ZRM core engine on a Linux box. Now we are able to run the ZRM core engine on Solaris itself. So a pure Solaris shop can use ZRM without getting a Linux server. The coinciding of this support with MySQL’s acquisition by Sun was not a planned thing
Enhanced Snapshot support: One of the coolest features of ZRM is to be able to take advantage of underlying storage infrastructure whenever possible. Since version 1.0 of ZRM we have provided support for backing up MySQL …
[Read more]Suppose you have a master-master replication setup, and you know one of the tables has the wrong data. How do you re-sync it with the other server? Warning: don’t just use any tool for this job! You may destroy your good copy of the data. If your table is large, you’ll probably want to use a tool that can smartly find the differences in a very large dataset, and fix only the rows that need to be fixed.
i completed all the paperwork to accept my new position at
sun today. now i
just need to drop it off at a ups dropbox or have ups pick it up.
at least they didn’t ask me to fax anything.
for a hardware company trying to become a software company, you
would think the process of “onboarding” would not involve writing
your address on a half-dozen different forms.
i will be a “member of the technical staff 4 - software.”
yeah, they say that they are working on updating the titles and
such for everyone.
$11.4 billion is wasted each year on software patent litigation, according to the End Software Patents coalition. How did it get to the $11.4 billion figure?
- Dan Ravicher of the Public Patent Foundation estimates that 55 software patent suits are filed every week.
- The American Intellectual Property Lawyer's Association states that a single mid-sized patent suit costs $4 million to litigate.
That's a lot of billable hours. However, it's perhaps not surprising given that patent swine like Global Holdings illegitimately attempt to extort patent royalties from unsuspecting enterprises:

Forge 2.0
was announced yesterday, and Jay and I were
bracing ourselves for an avalanche of bugs, which did not
come.
When Bug#34916 (Login not working on new forge site)
was reported, I thought nothing of it. It was simply the wrong
environment. The reporter could not log in, because he did not
have an account.
I explained the problem, and felt good about it.
Sometimes I experienced reporting a bug and being told that it
was intended behavior, not a bug, read the manual, thanks for
writing, and that was it. So dry and clueless. Not inspiring for
a further analysis.
So I took some minutes to explain what had happened, before
closing the bug with the fatal words.
And the reporter, …
