After receiving request to revive my book reviews, I’ve decided to blog about books I read again. If a known terrorist in police custody knew the whereabouts of a ticking bomb about to explode in a large city, would the use of torture be acceptable? Would it be helpful? I stumbled across Alfred McCoy through fora.tv. The program impressed me so much that I decided to pick up his book A Question of Torture.

Jira is a nice product for issue tracking linked to a SCM repository, yes it’s not free software but they provide a 5$ starter license for 5 users. But Jira lacks of a part that trac is doing very well, source browser, in facts Atlassian provides one: Fisheye but it’s really expensive Simply go to your Jira Administration, on the left click on Subversion Repositories (this menu appears after the installation of the subversion’s plugin).

After doing my seminar in Spain last month, one of the attendees sent me a secret note about what the CBO would look like in Oracle 12g. Apparently it’s re-engineered from ground and completely different from anything we’ve seen before. It goes beyond being automatic, intelligent and auto-tuning, it’s actually edible too! The New CBO Thanks to John Ospino for sending me this insider-info ;)

If you haven’t read them – here are the previous articles in Oracle memory troubleshooting series: Part 1 , Part 2 In Oracle, the HEAPDUMP dump event in Oracle allows you to dump various heap contents to tracefile. With adding the “level” parameter to this dump event, you can specify which heaps to dump. Julian Dyke has documented most of the levels here . There are two little known, but useful level bits for heapdumps – bit 0x100....

I thought it was about time I wrote about topics where I’m an amateur. This time: Experimental philosophy. As a computer programmer, I often entertain myself with writing computer programs. Last Easter I stayed up a few nights playing with an insignificant, but entertaining program. During a discussion with my philosopher uncle, I discovered that this program might provide some insight as to why determinism is, if not dead, then at least la..

C and I went to see Jim Sparks talk about his alien abduction experiences last night. It was a very interesting 4 hour talk and even though C is always extremely skeptical about these things, he found it interesting and says he enjoys going to these types of talks with me as it’s nice to see another point of view. I might write some more specifics on the talk later, but overall it was well worth the $30 per ticket for the most part. I’d def..

Here’s a neat trick if you want set an object in a specific state in a unit test, but you don’t want to violate encapsulation: @Test public void withdrawShouldReduceBalance() { Account account = new Account() {{ super.balance = 100; }}; account.withdraw(10); assertEquals(90, account.getBalance()); } @Test(expected=IllegalStateException.class) public void overdraftShouldThrow() { Account account = new Account() {{ super.balance = 5; }}; acco..

Karl Arao has written a nice blog entry where he used also some of my tools for visualizing and understanding performance of a RAC cluster suddenly gone slow. He presents a systematic approach he used for gathering evidence and also hopefully you notice that having the ability to easily visualize performance data (with PerfSheet for example) can be very helpful and time saving when troubleshooting non-trivial problems. Check his blog..

A couple of years ago I was on a trip to Budapest with a couple of friends. While roaming the streets we were passing by a casino and my friend insisted that there was a perfect strategy that would only lead to winning at roulette tables. Curious as I was I had him explain his theory. The system basically works as follows: First, you place a coin on red. If red wins, take your winning and start over.

One of my favourite CPUs from my CPU collection is the original Pentium 60MHz shown here. The reason that this model (SX835 with Gold top) is one of my favourites in not because it looks good, but rather that it was one of the Pentium models that had the famous FDIV bug. The FDIV bug was a problem with the floating point unit in early Pentium CPUs that resulted in reduced precision of division operations (FDIV is the x86 assembly languag..

ORA-04031 errors and monitoring shared pool subpool memory utilization with sgastatx.sql

Since Oracle 9.2 the shared pool can be “partitioned” into multiple parts. This was probably done for relieving shared pool latch contention for crappy applications (which use shared pool latches too much due bad cursor or connection management). The “partitions” are called shared pool subpools and there can be up to 7 subpools. Each subpool is protected by a separate shared pool latch and each subpool has its own freelists and LRU list. ....

Just found this while testing http://www.bing.com/ and thought I should preserve it here to be dammed sure I can find if when I want it. If the relationship is clearly “is-a”, I use inheritance. If it is more like “can-be”, I use interfaces. Eg, TextBox “is-a” Control, ArrayList “can-be” enumerated (so it implements IEnumerable).
