I was just reading the Groklaw commentary on Moglen and Florian.

What I find fascinating in this debate is the concept, or fear, that GPL software will somehow disappear.

Let me take an example from history, the MySQL vs Progress case where Moglen wrote the MySQL affidavit. Here is a link to the affidavit reference that Moglen supplied to the court.

A synopsis of this is that, Progress had released at the time a version of the MySQL Database which included their Gemini Storage Engine. They had not though provided the source code to the Gemini engine. This was a violation of the GPL. Progress lost their case and later made their engine available under the GPL. The engine is still …

According to the sources, Ellison is now willing to create a separate entity within a combined Oracle-Sun that houses Sun's MySQL open database software business in order to get the deal completed before a hearing Thursday by the European Commission.

UPDATE: this has already been declined by Oracle (thx to @janl).

Uwe Hesse, the Oracle Instructor look at result cache, another brilliant 11g new feature. He says, “There are many amazing New Features in the 11g version, one of them is the possibility to cache the result sets of statements, that access large tables but return relatively few rows. Think of it like automagically created materialized views inside the SGA.” Commenters contribute some thoughts on problems with result cache and latch contention.

A while ago I started a project which will be heavily IO-bound on the MySQL Server, the testmachine allocated for this had a DAS with 15 disks (although I only used 14) connected via external SAS (standard 3Gb/s half-duplex or 6Gb/s full-duplex on two ports).

I used sysbench for the tests, both fileio and oltp, although these results will be based on the fileio results. The setup with the disks in RAID10 (7 raid 1 sets, then striping over them) and later RAID50 (2 raid 5 sets with 7 disks each, then striping over that), the latter yielding better results.

Let’s take a look at 1,2,4,8,16 and 128 concurrent clients, with different IO schedulers, although using XFS.
The config for the raid controller was write-back, cached access, advanced readahead. 512MB battery backed cache on the controller.

Also, I tested both sequential reading (SEQRD in the graphs) and random read/write (RNDRW in the graphs)

Eben Moglen says EC case against Oracle-Sun is flawed. The value of open source. And more.

A MySQL is running happily on a machine situated in a land far far away. I grant access to a user@machine_aaaaaa (grant select on db.* to ‘user’@'machine_aaaaa’ identified by ‘password’; flush privileges;), send an email to the user saying it should run fine and happily go off my way. Mistake!

It seems this user can’t connect to the mysql gets access denied:
Access denied for user ‘user’@'machine_bbbbb’ (using password: YES)

Note that the machine the user is being seen from is totally different from the one I set up in the grant!! WHY?

run a reverse lookup on the ip of machine_aaaaa, turns out it shows machine_bbbbb. So I figure a big bad guy messed up /etc/hosts, I was right! `cat /etc/hosts` just to find an entry for machine_aaaaa blehh

Ok, solution is to remove the entry from /etc/hosts (after finding out it wasn’t even necessary and wasn’t even supposed to be there in the first …

For many years now, Sun provides ISVs with on-line access to Solaris, MySQL, PostgreSQL, Java, Netbeans, compilers, and much more.  This service is named EZQual and is used to evaluate Sun software,  and port and test applications on the Sun platform. To satisfy the demand we must be able to host many ISVs on a single system so we decided from scratch that the service would be implemented using virtualization, just like a cloud. Also, to provide a better user experience we decided to offer a remote desktop feature that, in conjunction with the virtualiztion, really offers what is known as a virtual desktop.

So far virtualization has been based on Solaris containers. Amongst other advantages, containers are easily provisioned by cloning a first template container. This feature is useful when - like us - you provision a …

From NY Post: Oracle Leader Blinks – Larry’s Olive Branch (to the EU), the NYpost sources apparently say that “what [...] Ellison is proposing is the creation of a firewall between MySQL and the rest of the combined company, and possibly setting up an entirely separate board for the MySQL business.”

There is no independent confirmation of any of this, so it may be true, or just air, or a trial balloon to see how other parties respond… I’m not going to add opinions to this, I just reckon it’s an interesting progression in the case. We’ll see how it pans out.

Update: so it’s not true (see Reuters).

(so now I’ll add my opinion…) Unfortunate in a way because from my perspective it …

WIKIPEDIA -

Irony (from the Ancient Greek εἰρωνεία eirōneía, meaning hypocrisy, deception, or feigned ignorance) is a situation, literary technique or rhetorical device, in which there is an incongruity, discordance or unintended connection that goes beyond the most evident meaning. It is the expression of one’s meaning by using language that normally signifies the opposite.

Types of irony
Modern theories of rhetoric distinguish among verbal, dramatic and situational irony.
▪ Verbal irony is a disparity of expression and intention: when a speaker says one thing but means another, or when a literal meaning is contrary to its intended effect. An example of this is sarcasm.
▪ Dramatic irony is a disparity of expression and awareness: when words and actions possess a significance that the listener or audience understands, but the speaker or character does not.
▪ Situational irony …
