SOA is dead! Was it ever alive?

There's nothing like a "financial correction" to make people wake up and start sniffing the crap that has been shoveled their way.

Waddya know? SOA is dead says Burton.

If I was paying for Burton services, I would be asking for a refund and an explanation as to why it took so long to identify the bleedin' obvious

The irony may have been a bit thick for anyone to realise that my story of Eric the Architect was little more than a lampoon on the generations of IT attempting to find a home within business (true friend - true story - honest!!!).

Guys - pragmatism rules. SOA never had anything to do with the bottom-line. Directly. And the indirect contributions lacked evidence and credibility.

In an excess of pragmatism, Miko Matsumura shut down the SOA center blog on the back of the Burton article. The new blog will be called the Whatever Center. Love the name, but will the dns changes ever propagate? I hope so, for Matsumura-san's integrity. Unlike WFTs transition to WTH, this is not a joke.

Personally, I'm with Justin Kestelyn:

The problems remain with us, whatever we choose to call the solution.

l'amour de l'ail

As I found in Leon: Ingredients and Recipes
garlic: you either like it, or you're completely nuts about it.

Well I must be nuts. Whether it is sweet delicious nuggets in the best Bak Kuh Teh, or sliced in your favourite Thai stir fry, garlic claims its' place as one of the four essential pillars of great cuisine (along with salt, pepper and chili).

One of my most memorable dining experiences was at the Stinking Rose in San Francisco (they have a great cookery book available).

But as usual, simple is best. I don't think there is anything better than fresh bread toasted with virgin olive oil, and rubbed with fresh garlic before immediate consumption. Warm, crisp on the outside, soft on the inside with the sharp pungency of fresh, raw garlic.

Tripping up on base64 encoding with webcache

Looking at an Oracle Portal installation recently, I wanted to call the WebCache invalidation API from SQL.

$ORACLE_HOME/webcache/examples/invalidation.sql sounds like a good idea, until:

Error report:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SCOTT.BASE64_ENCODE", line 51
ORA-06512: at "SCOTT.BASE64_ENCODE", line 57
ORA-06512: at "SCOTT.INVALIDATE", line 38
ORA-06512: at line 2

Uh-oh. The base64_encode function included in the script is having trouble with the password. A quick look at the code...
create or replace function base64_encode
p_value in varchar2
return varchar2 is

BASE64_KEY constant varchar2(64) :=
l_buffer varchar2(32767);
l_len integer := trunc(length(p_value) / 3);


for i in 0..l_len loop
l_buffer := l_buffer || encode_chunk(substr(p_value, i * 3 + 1, 3));
end loop;

return l_buffer;
end base64_encode;

Note l_len division by 3, then using it in the for loop. Yep, classic 0/1 base offset issue. Any password with a length of 3, 6, 9 etc characters breaks the code. Fixed with a -1:

for i in 0..l_len - 1 loop
l_buffer := l_buffer || encode_chunk(substr(p_value, i * 3 + 1, 3));
end loop;

But that raises more questions. What is this base64 encoding function doing here anyway?

At some point in time it might have been required, but Oracle Database has had the standard function utl_encode.base64_encode for at least a few versions. It encodes RAW so there's a bit of friggin around with types:
select utl_raw.cast_to_varchar2( utl_encode.base64_encode( utl_raw.cast_to_raw('password1') ) ) as B64 from dual;


I did note the comment in invalidation.sql to the effect that:
-- this old example is replaced by 2 files, collectively known as the
-- PL/SQL invalidation API.
-- the 2 files are
-- wxvutil.sql which does similar things as what invalidate.sql did
-- wxvappl.sql which is a wrapper of wxvutil.sql
-- both files are located in the same directory.

Well, these files are not in the same directory (they are actually in ../toolkit), and what's the excuse for shipping broken examples anyway, even if they are old and obsolete?

A case of severe backblogarrythmia

My backblog is giving me the irits. And what's worse I join the sad club of people who thought they cleverly invented a new word!

Backblog - Overflow of incidents you intend to write about on your weblog.

However, perhaps I can claim backblogarrythmia as my own:
.. a disruption in the regular flow of weblog posts, often caused by overwork, booze or a new romance. Primary symptom is the backblog, which in turn can exacerbate the problem through increased levels of performance stress. Treatment: JFPS*.

I used to work in a factory where I swear one of the leading hands had a personal goal of inventing a new word everyday. He'd casually call over something like "Hey, pass me the gumlicker would ya?" and take great pleasure in our confusion. He'd be mock-shocked of course at our "ignorance", and delight in explaining the word and how stupid we were for not knowing it. Crazy thing is, he'd always have a great and usually convoluted etymology.

He did this pretty much every day I knew him. Just an average working class bloke, with an average education. But I always secretly admired and envied his creativity with words, wondered where the inspiration came from, and whether he'd use the gift for anything more than keeping his workmates from boredom.

Me? The only words I invent tend to arrive as serendipitous typos. Yesterday's effort:
Museover - particularly thought-provoking and succinct tip or pop-up text that is displayed when you hover your mouse over an icon or word.


Update 27-Jan: It's official: museover and backblogarrythmia are in the (pseudo)dictionary
