To infinity...

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... Find the sum of all the even-valued terms in the sequence which do not...(read more)

Project Euler

jop — Wed, 11 Feb 2009 16:44:00 GMT

I wanted to try my hand on solving the Project Euler problems. Here is my solution for the first problem. If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of...(read more)

Slow Start - Testaments and Books

Here is my answer to Keith's Bible App challenge . I know the deadline has already passed but I want to do it the TDD way, so here it is. Again, the requirements. The user should be able to search for books based on a selected Testament (Old and New...(read more)

Markdown Viewer

jop — Mon, 24 Nov 2008 00:30:00 GMT

I'm not really fond of browser based text editors - especially the one used in here in devpinoy. I still write my posts using my favorite editor - gvim , and then paste them over to the blog software. That is sufficient if you are only writing plain...(read more)

I can't stop but smile at what I've written in this forum thread . A decade ago, I am constantly having this similar debate with my managers, project leader, team leader, quality engineers, etc. about the merits of unit testing. As I was still...(read more)

How to use Patterns

jop — Mon, 30 Jul 2007 15:40:45 GMT

Erich Gamma said: Do not start immediately throwing patterns into a design, but use them as you go and understand more of the problem. Because of this I really like to use patterns after the fact, refactoring to patterns. One comment I saw in a news group...(read more)

Estimation

jop — Tue, 24 Jul 2007 17:02:00 GMT

Today, I attended a seminar about Function Point Analysis . To me, this seems to be a very magical way of estimating a piece of functionality. It is so different from that way I used to come up with my estimates that, though I haven't tried it yet...(read more)

Domain Experience

jop — Sun, 15 Jul 2007 16:38:08 GMT

How come certifications are based on the technical skills of a programmer rather than business expertise?

If a manager of a company needs a C# programmer for their accounting system, isn't it more logical to look for a developer that has a good grasp of accounting which also happens to know how to program in the target language?

Unless your business is teaching technology, why would a company look for those certified in a certain brand of technology?

VS.NET: Reference EXE assemblies

jop — Thu, 21 Jun 2007 05:49:00 GMT

Nice! Visual Studio 2005 now allows Class Library projects (DLL) to reference Applications (EXE).

On Visual Studio 2003, EXE projects are not listed on the Add Reference dialog. The .NET framework does not put any restrictions on what you can reference. I think the IDE programmers thought they're helping us (or me) by only showing the DLLs there.

It's a problem because I used to work on some applications that are not big enough to warrant separating the UI and the core logic. I would only have a single EXE assembly but I am forced to create a separate assembly for classes that needs to be tested because my test projects can not reference the EXE file.

I am currently working on a small utility application so I tried it just now and it worked! Very nice...

Now that's what I call a desktop!

jop — Wed, 30 May 2007 14:42:00 GMT

Think of the possibilities:

Magic the Gathering
Internet mahjong; with realistic tile shuffling -- none of that randomizer stuff
Solitaire, the way it should be played
CRC cards!
UML
Billiards
Table Hockey
Piano
Drums (pressure sensitive?)
Massage tutorial !
DJ mixing table
Computer sculptures
StarCraft II
And finally, tables that turns blue all of a sudden...

Composed Method Pattern

jop — Tue, 29 May 2007 16:59:00 GMT

Msg #129624 on the extremeprogramming Yahoo! Group

Some people swear that they would rather see all the code in line,
rather than separated out into small methods. I think that the
in-line people should be prevented from breeding.

-- Ron Jeffries regarding the Compose Method pattern.

Haha!
