Oracle experiences...

In my current job i have the pleasure to work on an Oracle powered environment.

That has allowed me to get enough knowledge to give a personal evaluation of it, compared to the newest MS database server MSSQL 2005.

In summary, MSSQL 2000 has nothing to do against Oracle 9i or Oracle 10g, in that case MSSQL 2000 looks like Access with Steroids.

But when we put in the mix the latest and greatest MSSQL 2005 things change. Under such situations MSSQL 2005 goes along the way of Oracle 9i, but fails to reach the performance and tweaking capabilities of Oracle 10g.

Oracle has put lots of effort on simplify the Oracle installation and management of the database, but still lacks to the easy of use of MSSQL.

My current home project is being developed on MSSQL 2000, but it already pass some initial testings on MSSQL 2005, so, it is almost guaranteed that by the time its first version is out, it will be running on it.

The next step will be to move my ADO components to dbExpress so i can proceed thanks to DataSnap to support Oracle and MSSQL on deployments.

Why picking MSSQL over Oracle after saying that the last one is better? well, simple, easy of use, i need to have the initial version out soon and there is no time to spend on a database migration.

DeadLocks? well that was the big cons with MSSQL 2000, but i must admit that having all those locking problems did help me improving my SQL skills and my general knowledge of the MSSQL engine. What about Oracle? well, so far, it has behave properly, but we havent hit the system with enough transactions to safely say that is better.

What i do know is that Oracle manages a better locking system, If i'm not mistaken it is applied on a row level , now you can specify that manually on MSSQL (2005 has it by default) but come on wouldn't be nice if you dont have to specify your locking hints everywhere in your SQL statements? (yes you have to if you are doing any serious enterprise system).

Now, I'm going back to my duties and i will keep entering more rants on system performance later.

Latest news: New Delphi "DevCo" maybe announced on May 8.

Well, all this is based on news reported on one of the best Spanish language Delphi forum, Club Delphi , a well known spanish blogger and one of the main Borland Software distributors in Europe Danysoft.

It seems that on May 8th, in a conference in Spain, the new company will be announced. The article mentions that the new company will be based in Europe.

The article also mentions that is likely that the new "DevCo" will not be part of a well known buyer but a new and independent company.

The existence of a strong Delphi Market in Europe and also the good and strong anti-monopoly software rules plus protectionist from the European Union will be a plus to help "DevCo" in its way to the top.

Now, is this true? no idea, but May 8th is not that far ago, so i think we can wait a bit and find out.

Delphi Rox!

Linux and Oracle.... NOW I really love Delphi.

Well, these days I had to deploy one of our company projects in Linux and Oracle (Just in case, it is not built on Kylix).

The plan was to install Red Hat 4 ES and Windows 2003 server on two different VMWare machines running on my Windows XP computer all linked in a nice virtual network.

It has being a while since I play with Linux, last time I did I used the Mandrake Linux distribution more than 5 years ago, and it wasn't a pleasant experience. But I assume that more than five years later, I will have the closest thing to Windows I can imagine on the penguin environment.

Gosh I was totally wrong. My mission was basically to prove that we can have a full product installation using ONLY the GUI (Gnome /X-Windows), you guys must understand that giving this kind of statement on a fully Java/Sun/Solaris environment is the closest thing to a blasphemy only overcome by the use of Microsoft / Windows related products on our environment (which I'm doing by introducing Delphi :))

Anyway, as a summary of my experience:

* Red Hat 4 installer is great, it was the closest thing to the famous "Next, Next Finish" we are so used to in Windows.
* Soon or later you will have to use the command line.
* Gnome desktop is still far behind Windows.
* Linux guys like to build a mist of mystery on their products. All the things I did in order to install Oracle on Linux can be done on the GUI, *if* someone puts a bit of time on finishing the GUI and adding some of the tricks that can be done only through the command line. (permissions is an example).
* Oracle installer should ask for the root user/pass and do all the required installs without having to stop and ask the user to manually go, change user and run scripts to be able to finish the installation.
* Linux REALLY needs some good RAD environments. (Did I said Kylix?)
* Copy/Paste is a pain, some applications will not recognize the copied items from other apps.
* WARNING!! The File Browser doesn't recognize the files with names .something. This caused me a bunch of issues cause Oracle installers used lots of files with that kind of names. (e.g. .extract_args.
* I ended up copying the files using the command line. If you ask me, that is SAD. (Yes I did enable to view all file types and hidden files, didn't work)

Well, I can keep typing but it is enough, Linux is cool, but gosh, once you work with Windows and Delphi you realized how nice and green are the lands on this side of the computer world.

I can't believe people still pushes for terminals and command prompts, I mean think about it, movies, TV series, internet, everything shows the new generation of developers (kids) that it has to be graphical, kind of "Minority Report" feeling.

Terminals look cool, for all of you hacker lovers, but, it is the 2000's, that is a no no, now days.

Cya all.

Windows Vista will not use .Net

After all, .Net is taking some time to lift off. The following articles extracted from a good discussion on the borland newsgroups show us how the new Windows operative system ended up not relying on the .Net framework.

and ...this other ones covering the API and GUI.

Personally, I'm more interested on future native Win64 support. If Intraweb is able to catch up and improve its performance (which they did in version 8), then i will not have any other use for .Net (which i think is only useful for web apps for us Delphi developers) in the short term.

Transactional Data Modules on Delphi 2006

Tonight i was working on my project's middletier using DataSnap and i decided to add a new Transactional Data Module, perfect, i click on File / New / Other and select the MultiTier tab... ooops, it only says Remote DataModule!!!

Where is my Transactional Data Module!! Well, it seems that the Wizard didnt make it for the official Delphi 2006 release (as i said officially), BUT... after a quick "let me ask Mister Google" i found this good entry on Borland's Chris Bensen blog. Good stuff it is there, notice that you will have to enter "both" (Free) in the component factory section if you want to specify support for both Single and Apartment Threading Models, the option in the wizard only offers Single or Apartment.

Anyway it seems that Delphi 2006 supports them fully and there is no problem with it. (We already deployed our newly D2006 compiled modules).

Another way to do it is just to open your project with Delphi 7 and add the transactional data module, save, close and go back to D2006. (Hey, i still use the D7 help file :P)

Marco Cantu's eBook Delphi 2006 first draft

I mentioned before on the borland nontech newsgroups that Marco Cantu was planning to extend his Mastering Delphi 2005 book.

Well, here is the link to his initial Delphi 2006 ebook first draft. I can say that Marco's book is great, it is part of a good collection of Delphi .Net books on my office, which i will be waiting to increase with his next book, which i expect to be available when Delphi 2007/2008 comes out.

Enjoy the good reading.

2005 is gone, welcome 2006!

Well, personally and professionally 2005 was a great year for me, i spent my Christmas in my beautiful and warm country, the perfect way to close a good year.

But now, it is 2006, and what better way to start the year than with the BEST DELPHI EVER, yes sir, i am right now installing the Man, the Mighty One, the only Delphi not bashed so far in the non-technical borland newsgroups... Mr. Delphi 2006.

So far so good, i'm installing right now my standard components: JVCL 3.10, SUISkin and ExpressGrid.

If all these guys come up right, then we are ready to move, yup, i'm not thinking twice, i'm going all the way, i'm migrating from Delphi 7. It is worth it and the feedback so far has been A+.

So, people, the time is now, Delphi 3, 4, 5, 6 and 7 users, we have our safe spot is Delphi 2006.

Let the party begin.

Pst. It looks like i will have a lack of sleep this coming days. :)

Post taken from the delphi.non-technical newsgroups. I'm including the text in order to avoid confusions, if you want to see the real text, go to the google newsgroups, it should show up there.

Members of the Delphi Community,


As you've no doubt read in other threads in this newsgroup, I have left
Borland to seek new opportunities at Google.

This was not a sudden action. I have tried my best to ensure a smooth
transition for the Delphi team, starting with transition plan
discussions with Borland management more than nine months ago.

Delphi is built by a team, not by any individual. Far greater talent
than mine has come and gone from the team, and Delphi presses on. More
importantly, far greater talent remains in the team, some of it as yet
untapped.

As you may know, my philosphy is that teams should be built to
anticipate, tolerate, and support the comings and goings of individuals
on the team. Everyone will eventually leave the team - either by
choice, or by pine box. To ignore this is childish.

I have full confidence in the Delphi team to continue to deliver the
right stuff to keep Delphi current, innovative, and competitive for
years to come. Though there have been some difficult spots between
myself and Borland corporate management, the internal changes in
attitude and messaging in recent months from Borland corporate toward
Delphi have turned my faith in Borland supporting Delphi back toward
the positive. I'm sure that will only get better as Todd Neilsen
steps in as the new CEO.

I'm also pleased that in some small measure my departure is creating
opportunities for advancement within the Delphi team, and that Borland
management (Boz and Steve Todd) was very supportive of "redrawing the
map" under the guidance of Allen, Michael, Eli, and myself. Several
individuals on the team have been promoted in title and/or in pay as a
result of this change. Many of those have not seen promotion or pay
raises for as long as 5 years. Borland has also committed to opening up
several new positions in the Delphi group in Scotts Valley, which may
be filled with entry or mid level engineering talent. This alone is a
significant reversal of the "No new hires in Scotts Valley" edict
earlier this year by then-CEO Dale Fuller.

I was not snatched away from Borland, and I am not leaving Borland for
lack of money. I sought out Google, and I'll be making at Google
exactly what I made at Borland, which is nicely comfortable but not
excessive. There were other suitors (including the obvious one) but,
quite frankly, Google outmaneuvered them.

Could Borland have bought me back? No, because I didn't leave for
money. Why, then? Opportunity. I'm going to Google to pursue ideas
and opportunities that are simply beyond Borland. I love Delphi, I
know it inside out, but there's a lot more in me than just Delphi.

After 15 exciting years doing a wide variety of things at Borland, it's
time for me to do something /completely/ different.

This is not goodbye. This is just changing channels.

-Danny Thorpe
Engineer, Google.
