Latitude D600, Pentium M 1.6, 640MB RAM, DVD/CDRW, Bluetooth, 802.11b/g, 5400RPM 40GB HD. It rocks!!! Upgrade from an Inspiron 7000.
But, here is my rant. It seems to me that no one is making a Bluetooth computer mouse. Microsoft does but you must use its trans-receiver (I have one). Please can somebody out there make one? I'm sure it will make you a lot of money. Notebooks are a necessity, Bluetooth is here to stay, and you could see it coming Bluetooth enabled devices are the way to go.
I went this morning to the Windows 2003 Launch Event. Out of everything they showed, I liked the Shadow Copy feature in Win2K3. Right-Click on a file, Properties, a new Tab appears called ‘Versions ...’ don't remember exactly. But new tab has a list of versions for this file a la SourceSafe. (Neat!!!). BTW, SharePoint looks great I would definitely check it out.
After being brain washed by the marketing guys, I proceeded to the Developer session where I learned a few tricks.
I have heard this entire buzz regarding RegEx before but I kind of never got into it. That’s until today when I need what seems to be some simple pattern. I’m planning to have this pattern match values of a business object property. In other words, this property can only be ‘ALXBIETOS’ or any combination of these characters. Characters should not duplicate.
Ok, that was the story. This is what I got so far…
^[ALXBIETOS]{1,9}$
How can I tell it not to allow duplicate characters?
It’s been long long while since my first blog. Not a real excuse but too much coding, family, and friends occupying my time.
Anyhow, enough with the excuses and let me share my latest adventure. I am writing this set of business objects most being a bunch of collections.
When writing collections the first thing that comes to mind is iterating to a lot of records will be really slow. Well, no more thanks to a little tip from Don Box based on an interesting article on iteration performance in .NET by Trevor Misfeldt. I made the changes Don suggested and for me Iteration went down from 25.94 seconds to 3.734 seconds.
Thanks Trevor, Don
Currently, I’ve been really busy working on Engine-Collection-Class design (ECC). I am writing Business Class Objects to support a system with a least 30 to 40 entities. Today I am beta testing my classes before others developers could use them.
The biggest requirement above all things is “Flexibility”. On previous versions, it was really messy to change data sources some clients wanted to run the system using Oracle, and the majority preferred SQL Server. Another problem was that there were no separations of layers, so changes to the UI were almost always a complete re-write. Anyhow, the next release should account for Windows, Web and maybe the use of webservices as clients to my BO. Now for the DAL components, I am reading some articles but have not decided on any approach yet. The DataFactory class design by Dan Fox looks really interesting.
I want to thanks Scott W. for this outlet... :-)
