A chat with some of my favorite people: the makers of PL/SQL

On Tuesday this past week (March 24), I had the honor of spending some time at Oracle headquarters with two guys from the PL/SQL Team -- Charles Wetherell, the brains behind the optimizing compiler, and my long-time sparring partner Bryn Llewellyn, the public face of the team. I make the pilgrimage to HQ every year or so to share PL/SQL stories, meeting different team members each time.

I talk about what I am doing with PL/SQL and what I see out there in the big world of PL/SQL developers. They talk about what they are doing with the language, and where they see it going. They usually even pretend to give consideration to my viewpoints! Aw, just joking. They are most respectful.

Now that Oracle Database 11g Release 2 is well into its Beta Program, most of the developers at Oracle HQ are hard at work on the end-game activities -- while some are already starting to plan the content of the next major release. It was great to have the chance to talk, strictly off the record, with Charles and Bryn about their ideas for the next big steps in PL/SQL, and to put forward some of mine.

And while I cannot go into any details, I can tell you that it is very clear that Oracle remains committed to supporting and enhancing the PL/SQL language in very substantial and, in at least one case, for me, quite surprising, ways.

I can also report that the team generally pays attention to input from their users (PL/SQL developers). Not only that, but the ideas proposed and voted on at ILovePLSQLAnd.net are treated with the utmost consideration. So please, please, please....if you have not yet visited this website, please do immediately and vote on the PL/SQL enhancements you feel would benefit you the most. When Oracle Database 11g Release 2 becomes generally available, I will update the list on ILovePLSQLAnd.net to show what has been implemented.

And, as always after a meeting with my friends on the PL/SQL team, I am reminded of two things:

1. How glad I am that we have people of their caliber (real computer scientists) planning out and implementing changes to PL/SQL - and not people of my caliber (that is, largely self-trained and quite amateurish by comparison).

2. That for many years to come, PL/SQL will continue to be a truly fine language in which to write software and implement business requirements.

So, happy coding, my fellow PL/SQL developers! Rest assured; our future selves will be more productive and ever more pleased with the language with which we spend so much of our time.

Random reactions to Consumer Reports' Auto Issue

The mouths of real men don't water when they hear that the Sports Illustrated swimsuit issue is going to hit the newstands. That's adolescent stuff.

No, real men get all excited when they hear that Consumer Reports is about to publish its latest Auto Issue.

Consumers Union (publisher of Consumer Reports, consumerreports.org and many other invaluable resources) is an amazing organization. They exist for one reason only: to provide unbiased information to consumers to help them buy the highest quality, safest, most reliable product that best fits our needs. CU accepts no money from corporations, and certainly nothing from the companies that create the products CU evaluates. CU has no axe to grind, no reason to do anything but totally objectively test and analyze stuff, to help consumers get the best deal (not necessarily the lowest price).

Companies are even barred from using CU results in their own advertisements (usages like "Look, CU says our car is the best!" are quickly challenged in court - and won).

The Auto Issue offers detailed evaluations of hundreds of cars, both new and used. It is a must-read for anyone planning to buy a vehicle (not that there's much of that going on these days). I definitely do not plan to buy a new car. I hope to never again have to buy another car again, in my lifetime. At least not one that uses gasoline. But it is still fun to read.

Here are some things that caught my eye:
  • First the cover: at first glance, it looks like many other magazine covers. Lots of bright colors, very nicely laid out, etc. But there is something really different about it: right on the cover, next to the titles of articles and sections in the magazine, are the page numbers on which those articles appear! Page numbers? Radical! Usually, magazines hide page numbers so you have to leaf through the magazine to find the article of interest, coming across ads in the process. Since Consumer Reports has no ads, there is no reason to do that.
  • On page 15, CR offers "Automaker report cards", overall scores of brands (Honda, GM, Hyundai, etc.), rather than particular models. Honda is #1 with a score of 78. 95% of the vehicles tested are recommended by CR. Incredible. Second is Subaru, with a slightly lower score but 100% recommendations (disclosure: we are a Subaru family; my wife loves the all-wheel drive). Toyota is third. Out of the 45 brands shown on the page, four of the last (lowest scores) five brands are Ford, GM and Chrysler, in that order. And, horribly, CR could not recommend even a single Chrysler model. That is just downright embarrassing.
  • Oddly, the cover shows a Honda Fit as the "top value" for 2009, but in its "Top Picks" section, the Fit does not appear. CR must have some very interesting algorithms for making its choices.
So the bottom line is that if you are thinking of purchasing a car, you would be downright nuts to not consult the Auto Issue first.

Best thing to do is subscribe online: just $26 a year gives you full online, searchable access to all of CR's information. You will recoup that small investment many times over, both in terms of money and value for you and your family.

One final comment: I believe that CU has the potential to radically transform the distribution of power in our capitalist society. Today, corporations push products at us, convincing us to buy their stuff mostly through manipulation (ads), coercion (high pressure sales) and ignorance (most Americans are poorly educated, non-critical thinkers). With CU, you can ignore the ads and focus solely on the data; at a minimum, you can use CU to avoid purchasing unsafe, nasty, poorly-designed products.

I strongly urge you to join CU today, and help make it more effective, able to test more products and take more action to protect consumers. It will be the best investment you make in 2009. I guarantee it.

Hard to blog through sadness....

It's been a long time since my last blog. A big part of my noted absence (ha!) from the blogosphere is that we are busily freezing code for release 1.8.3 of Quest Code Tester, plus I am building a thorough automated regression test for this tool. Wow, that takes a lot of time, even when I use Code Tester to help me test....Code Tester.

I wish, though, that that's all it was.

Instead, I have had a hard time returning to my blog because on February 2, a 23-year old friend of my son, who we have known since he was six, committed suicide by jumping from the top of his apartment building.

His suicide hit me hard, not only because I knew Jeff when he was little (we hadn't actually seen him for more than a few passing words and minutes for the last several years) and because his father was a good friend of ours. But also because it has been hard for my mind to not stray into thinking what it would have been like if Eli (same age, many similar general life circumstances)....

And then my mind shuts down in pain and horror, and I move away from those thoughts, leaving just emptiness, sadness, and little motivation to gush about the bright corners of the world.

Scrabble Oddities

Veva and I have been playing Scrabble nightly for a while, and tonite I was quite amazed at the pattern of my tiles. Of course, every game is unique and it is not uncommon for some strange coincidence to happen (for example, two night ago to choose who goes first, Veva chose a Q. "Wouldn't it be funny if you picked a U?" she said. I shook the bag, stuck in my hand, grabbed a tile, and announced without looking at the tile "A U!" and it was). But this was one remarkable game.

Here are my letters through all but the last few turns (? is a blank):

KGIEAOE
EEEOOOA
EEEAAAO
SEEAAIO
SSEAAOI
SYAAOOI
NEEOOAI
NPAAIOO
EEOAAI?
VEEAIO?
EEUUOI?

Out of all the consonants with more than one point, Veva had:

QXZJHHVYPWWDDDCBB

And I had

KGYPVCD

What an unbalanced game!

Oh and four nights ago, she picked an X to choose who goes first...and I chose a Y!

What are the odds of any of this happening? I find that actually to be a silly question. There are no odds. It's just stuff that happens.

Ah the blatant cynicism of Israeli leadership

Check out this article (text at end of this post in case the article disappears):

http://news.yahoo.com/s/nm/20090122/ts_nm/us_palestinians_israel_swap_1

I find it somewhat astonishing....here's what struck me:

** One of the main justifications that Hamas used to resume its rocket attacks is that Israel violated the truce the whole way through by not relaxing the blockade and allowing Gazans economic freedom and growth so they could live normal lives.

** One of the main aims of the latest awful attack on Gaza was to decimate Hamas leadership.

** Then Israel unilaterally calls an end to its hostilities, clearly driven by the desire to not have an active war going on as Obama is inaugurated. Plus its attacks on civilians, civilian infrastructure and THE UNITED NATIONS became so blatant and revolting that even Israel could not withstand the international condemnation.

** Now they refuse to relax the blockade for anything but minimal flow of humanitarian aid (all agencies complain that they cannot get what is needed into the strip) until Shalit is released!

** And it looks like they are agreeing to release 450 "senior militants" of Hamas, previously they had balked at this.

So...they find yet other ways to continue to collectively punish all Palestinians in Gaza, which strengthens Hamas and weakens Abbas. And they will now send back into Gaza a previous generation of leadership of Hamas, that will now step forth and become the NEW generation of leaders.

Isn't this just insane? Is there any reason to really honestly believe that the Israeli government and military is interested in anything but keeping this conflict going?

After spending years (from 2001 to 2007) working obsessively on this issue (Not In My Name, Junity, Refuser Solidarity Network), I have come to the following conclusion:

If you want to try to predict what will happen next in the Israeli-Palestinian crisis, then just imagine the worst possible scenario. That is almost certainly what will unfold. So here is my prediction:

Israel wants to make life so horrible for Palestinians in the Gaza Strip (effective imprisonment through military blockade and deprivation of 1.5 million people) and West Bank (effective imprisonment through the "Security Wall" and endless stealing of their land through "settlement" expansion) that some small, but growing number of Israeli Palestinian citizens will choose (feel driven to) violence (suicide bombings) to protest.

Then Israeli Jews can claim that they tried everything, but even their own fellow citizens who are Arabs will not let them live in peace. And then the ethnic cleansing of Palestinians from within the current boundaries of Israel may commence - thereby ensuring the "Jewish democratic majority" (ah, the oxymoronsn!) of Israel.

Well, I sure am ranting today, so I will finish it off with this:

I believe that the greatest existential threat to the State of Israel comes from the Ameerican Jewish community, whose leaders and organized constituents treat Israel as a kind of Golden Calf, idolizing it and serving as apologists for it, no matter how awful its actions.

And this blind support for Israel will allow it to dig itself into a deeper and deeper hole, until it becomes a true pariah state. Hey, but at least it will be "Jewish."

After Gaza war, Israel sees Hamas prisoner swap

By Dan Williams

JERUSALEM (Reuters) After battering Hamas in the Gaza Strip, Israel now hopes to push through a prisoner swap to retrieve a soldier held by the Palestinians since 2006, Israeli officials said Thursday.

They said Israel was conditioning any lifting of its Gaza blockade on immediate progress in Egyptian efforts to free Gilad Shalit, and would be willing to relax its objections to a list of Palestinian prisoners which Hamas wants released in exchange.

The Islamists demand amnesty for 1,400 inmates, including 450 senior militants. Israel long balked over the latter group, saying their release would sap Palestinian President Mahmoud Abbas's peace strategies by bolstering rival hardliners.

But after its 22-day offensive against the Hamas administration in Gaza, Israel appears to be more flexible.

"There is a sense that we can afford to relax our criteria on the prisoner release, as any benefit to Hamas would be more than offset by the damage it sustained in Gaza," said one Israeli security official.

The official said Prime Minister Ehud Olmert wanted to clinch a deal before he is replaced in a February 10 election, though it was not clear whether the Israeli security cabinet could approve all of the names on the Hamas release roster.

Addressing reporters Thursday, Olmert said: "I believe that the military operation in Gaza created levers that can help in speeding the return of Gilad Shalit ... I will not elaborate."

Security cabinet minister Binyamin Ben-Eliezer told Israel's Army Radio that new discussions on a possible prisoner swap had not yet taken place. He added: "I am among those who would be willing to pay the highest price for Gilad's return."

EGYPTIAN MEDIATION

A top Israeli defense official, Amos Gilad, travelled to Cairo Thursday to discuss ways of consolidating a January 18 truce which ended the Gaza offensive. Security sources said Gilad would raise Shalit in his talks with the Egyptians.

The Gaza offensive killed 1,300 Palestinians, many of them civilians, and wrecked the impoverished strip's infrastructure.

Western powers have since called for Gaza's borders with Israel and Egypt to be more open, while supporting Israel's demand that Palestinian cross-border rocket salvoes cease and that Hamas arms-smuggling from the Egyptian Sinai be choked off.

Israel stepped up the crippling Gaza embargo after Hamas, which won a 2006 Palestinian election, seized control of the territory in a brief war with Abbas's forces the following year.

The Israelis rule out restoring normal operations at Gaza's border crossings unless there is a deal on Shalit, an army conscript seized by Hamas-led gunmen in a June 2006 border raid.

"I'll tell you this here, in plain Hebrew: apart from (the passage of) humanitarian goods, there will be no crossings (opened) without Gilad Shalit," Ben-Eliezer said.

Entering the new year with a bang

First, happy new year to all my readers (no matter how few you may be). I hope the holidays were good to you.

As you no doubt are aware, Israel has once again attacked with missiles, bombs, artillery, tanks and ground troops one of the most densely populated areas in the world: the Gaza Strip.

Ostensibly, this was done to stop the rocket attacks from Gaza. Only the most apologistic of Israel's supporters really believe this. These attacks have been going on sporadically for years, with very few casualties (though every single death is awful and anyone authorizing the firing of those rockets against civilian targets should be considered a war criminal and brought to the Hague for a trial).

Now with Israel's latest application of the fifth most powerful military force in the world, not only have over 100 Palestinian women and children been killed, but more Israels have been killed in the last ten days than in the several years previous.

And does anyone really think this will stop the rocket attacks? I don't think there is a chance of that happening as long as Israel continues to treat Gaza as the world's largest open air prison, controlling (and greatly restricting) access to food, medical supplies, energy, etc.

Anyway, most seasoned observers think this invasion has more to do with upcoming Israeli elections, and the need for Labor (whose head is now the Minister of Defense - Ehud Barak, who is in my mind another war criminal who should be sent to the Hague) to show that it can be as tough on the Palestinians as the most right-wing Likudnik.

I am sure that is at least partly true. I believe, however, that the invasion and destruction of Gaza is first and foremost intended as a message for incoming President Obama. Israel (its civilian and military leaders, in any case) is showing that it controls events when it comes its own sphere of dominance. It is saying to Obama "We decide what happens around here, not you."

It is, really, quite a big and obnoxious "f#%k you" from Israel to Obama.

Think about it. With this invasion, Israel has forced a change in the agenda for the incoming President. Obama must (and intended to) focus on the economy and spend political capital immediately to get a recovery plan in place (one that helps more than financiers).

Yet now he must address the violence in Gaza, and what will he do? Is he going to do or say anything that is critical of Israel, thereby risking a firestorm of criticism in his first days in office? The Israel apologists will go ballistic: "See, we told you! He is no friend of Israel." No way. He is going to eat it, all of it. He is going to acquiesce to Israel's terrible and terrifying destruction and killing of innocents. He will join the chorus blaming Hamas entirely. And in doing so, he will send a clear message to the Arab world: expect nothing different from me when it comes to Israel.

Leaving Israel (its screwed-up, "kill now and kill later" leadership, in any case) to go further down the path to stoking flames of hatred, ensuring war, and diminishing its chances of survival as a Jewish state.

Poor Israel. Just when it most needs a real friend, it will force that potential friend to become merely another servant to the cause of Jewish extremists.

Time to celebrate!

Yesterday was a very important day of celebration for me.

It marked the last day of 2008 that I will enter or leave O'Hare Airport.

According to American Airlines, I traveled 128,053 miles on their jet planes this year.

Terrible way to spend a life. Well, of course, it could be much worse. I have little about which I could complain in my life. Except for being away from family, friends and home.

Now, however, I am home. It is freezing cold outside my home, but warm inside. I am happy and content.

I will not, should not have to return to O'Hare until January 12 -- and that will be for a trip to Puerto Rico.

Not so awful, I suppose....

A whole class of truly stupid television commercials

You've heard of HDTV, right? High definition television. It promises brighter colors, crisper sound, blah, blah, blah. All right, so say it is all true. How do you convince people that they should buy a HDTV (besides lobbying our elected representatives to pass a law mandating a switch to digital signals and a required switch in equipment)?

By showing them just how wonderful HDTV will be.

And how do the TV manufacturers do that? You (Sony, Panasonic, LG, etc.) buy time to run ads promoting your incredible products.

So here I am, sitting on my couch, watching ads in order to get back to the Daily Show or the Colbert Report (the only regularly scheduled TV I watch). And on comes an ad for HDTV.

The ad features lots of bright colors and vigorous motion and loud sounds.

"Wow!" I guess I am supposed to exclaim to my wife. "Isn't that HD great? I sure wish I had a TV that could show me those bright colors and let me hear all those incredible sounds...."

And then since my wife is not a guy and therefore not easily captivated by gadgets, she might say back to me:

"Dummy! You like those colors and sounds? Well, you're watching all that on your own television, right now."

Hmmm. I am suspicious. Is she playing a trick on me? My Primitive Man Brain wants a new shiny skinny high-def TV. But my Rational Man Brain has a hard time arguing with her logic.

And don't you, too? Isn't it a bit ridiculous for companies to promote the radically new and better resolution of an HDTV on a non-HD TV by showing how much better it will be?

A very odd job

Have you heard of World of Warcraft? It is a "massively multiplayer online role-playing game" (ahem, MMORPG) played over the Internet simultaneously by millions of people. The more you play, the more powers and weapons and so forth you accumulate (assuming you are not entirely incompetent). But what if you don't have enough time to do that? Wouldn't it be "great" (assuming you find anything about losing yourself in videogames to be "great") if you could simply buy these powers and weapons?

The maker of the World of Warcraft does not allow you to do this, so of course a "black market" arose to fill the need. Here's the quote from Wired magazine about this:

"Internet Gaming Entertainment, or IGE, made hundreds of millions of dollars as middleman for Western gamers eager to outsource the boring aspects of play to low-wage third worlders. The people who founded the company realized that scarcity of time and scarcity of virtual resources created a whole new market."

and....

"Despite the game companies' widespread prohibition of such transactions, their number has grown to support an estimated $2 billion annual trade, a half dozen multimillion-dollar online retail businesses, and an enormous Chinese workforce earning 30 cents an hour playing MMOs and harvesting treasure to supply the major retailers."

Now that is a very odd job: sitting around and playing videogames specifically to accumulate "treasure" that can then be sold to people who are able to attach a greater value to their lives than the "enormous Chinese workforce."

We live in a very strange world. For the full article:

Sister and Moshe: a phase of our lives ends

For many years now, we have had three cats in our house: Sister Itsakat (aka, Dinosaur Kitty), Moshe Jacobawitz (aka, Baby Seal Cat) and Mica (aka, Kangaroo Cat). Now, sadly, there is just one survivor: Mica.

Back in August, we put Moshe to sleep. He had diabetes and we have long sworn that we would not become caretakers (and, frankly, financiers) for deathly ill kitties. [Note: I wrote this originally in March 2008. Moshe then managed to live till the end of July, far longer than expected. We finally had to euthanize him, because he had lost half his body weight and we had to leave for an extended holiday. The vet clearly felt that we had already waited too long and he had likely been suffering. We felt bad.]

Sister died last year, just kind of stopped eating and then stopped breathing, once her thyroid medicine had no discernible impact.

They were both about fourteen years old at time of death.

Even though Mica is left, she is a rather late arrival to our home, having rescued her some five years ago from the home of our older son, Chris. A rescue was necessary because Mica was born with only three functioning legs and lots of internal organ abnormalities. Extensive surgery kept her alive, but the other two, big, black, aggressive cats in Chris' home made her life a bit uncomfortable.

Here's a picture of Mica.

So we took in Mica, but Sister and Moshe had been with us since Eli was seven, just after we moved into our Rogers Park home, and they were a part of our lives for a long, long time - and almost all of Eli's growing up.

And so I thought I would pay homage to Sister and Moshe.

Sister showed up one day in our backyard, just wandered in, almost certainly looking for food. She was a beautiful gray cat and she was impossibly skinny. Must have run away from her home or gotten lost, and didn't really have the hunting skills necessary to live on mice and rats outdoors.

Eli was obsessed with dinosaurs in those days. He put together dinosaur skeletons from kits, read magazines about dinosaurs, and so on.

Sister was so skinny that when Eli saw her, he said: "Mom, that cat looks like a dinosaur!" because her bones were stuck out so sharply.

Veva had some leftover salmon in the refrigerator. They fed it to the starving cat and she decided that there was no reason to leave our backyard. We took her in and Chris named her "Sister Itsacat."

She was always something of a standoffish kitty. She couldn't handle being brushed at all- I don't know if she was the victim of some abuse or maybe her skin was just too sensitive. Her fur was certainly very fine and soft. But she liked to be petted and was very willing to be held. She would just melt over your arms or shoulders. Here's a nice picture of her. And another.

Moshe, well, he was a very different sort of cat.

Soon after moving to Rogers Park, we started spending time at the Nature Center, a small enclave of a park surrounded by residential neighborhoods, a senior citizens home (actually a large complex of building), a university, and a cemetery. We volunteered there, helping to maintain the trails, and visited for holiday celebrations. The Center itself boasted a small "zoo" of sorts, with a variety of animals found on the property (and usually in need of some medical assistance). It was a wonderful place to be able to take a young boy, growing up in an urban environment like Chicago.

One day when we visited, we found that there were several brand new kittens in the Center. Their mother was a feral cat at the park and rather than have a small gaggle of wild cats growing on the property, they decided to find homes for the kittens. Moshe was one of those kittens.

When we first took him home, he was so small, he could sleep curled up inside Veva's slipper. He was tiny. But it was clear from the very start that he had no intention of staying that way. Sister had a fine appetite, but she didn't act as if eating was the most important activity of her life.

Moshe, on the other hand, was so enthusiastic about eating that he would mush his face into the bowl of food, chomp chomp chomp, and come away with food shmushed all over his face. His enthusiasm quickly paid off. He got big and he got fat.

And he was definitely the Alpha Male of the house, to which this photo can attest.

Yet he always remained at heart a kitten. Even when he clearly tired and arthritic, when getting up and down stairs was clearly painful for him, if I took out a string and dangled it in front of him, he would push himself up and go after that string. I could even get him to chasing his tool (well, when he was young, he really did chase his own tail, but when he was older, he chased the string around and around in a circle).

Moshe would have loved to play with Sister, but she was never the least bit interested in playing with him. In fact, she was very upset when we brought him home. She was never excited about sharing her home, and her salmon, with other cats.

Mica was definitely interested in playing with Moshe, but by then he was a good bit older and it was never clear if he liked playing with her or simply tolerated her. She was (is) much more lively, even with only three legs to hop around on. Plus, we removed both Moshe's and Sister's front claws, but didn't have the heart to do the same thing to Mica. She really only has just one weird claw on one paw.

So Mica would dance around Moshe, taunting him, poking her claw out, and finally Moshe would respond, and they would engage in a short dance. The dance would usually end by Moshe falling over onto Mica. Not much she could do about that, being about 1/4 of his body weight.

So...why, you be wondering, did Veva call Moshe the "Baby Seal Cat"? Because he had this endearing habit of lying on the floor and pulling his front legs up so that looked like a seal.

Moshe really enjoyed life. He enjoyed eating. He enjoyed sleeping. He enjoyed bullying the other cats, especially when it came to food. He like being vacuumed and was very well behaved generally whenever we needed to do anything to him (give him medicine, wash him, etc.). He loved to go out to the backyard and hang out in the sun. And if he somehow made it out of the yard, he never ventured far. This home was all he knew and it fit him just fine.

Sister had a taste of the world beyond our yard and if she got out, she could certainly end up at least several houses away. She was good at chasing down rats and mice, even without front claws. We finally erected an eight foot privacy fence around our house so we could let the cats out into the backyard and they would likely stay in the yard, though Sister would occasionally still find her way out.

Mica was totally a house cat; we could barely even get her to step out the side door and experience the wind on her face. That made her a very smart cat, since she would have been pretty much helpless in the face of the most mild of predators.

Our cats enriched our lives, but also made Veva and Eli perpetually at least a little bit miserable, since they were both allergic to cat dander. Sigh...so now that Sister and Moshe have died, and Mica has moved on to a new home, our house is pet free and pet dander free (well, mostly), but also a bit empty feeling.

Maybe someday we will bring a hypoallergenic animal into our lives. But for now....we will be pet-less.

A wonderful trip to Portugal

At the beginning of November, my wife and I traveled to Portugal for a week. I gave a two day training in Lisbon sponsored by my friends at Dutec; we also spent a weekend in Porto, which is 2.5 hours north of Lisbon, and the home of port wine.

We had a really wonderful time. Carlos and Joao of Dutec were fantastic hosts, very generous with their time, taking us out to dinner each night, taking care of all the details of our stay, putting us up in a very nice hotel, the Villa Rica. One evening, we went to a restaurant with fado singers - that was a great experience!

And in Porto, Manuel of University of Porto put aside his many responsibilities to show us around this beautiful, very old city (continually inhabitated by humans since 1300 BC!). We even got to meet his wife and daughter (Margerita was one of the highlights of my trip!), as well as that of his developer (and first winner of the OPP Test a Thon), Filipe de Silva. Filipe's 14 month old son, Francisco, was a tremendous amount of fun.

You can see photos from our trip at:

http://flickr.com/photos/60694364@N00/collections/72157609008492753/

Of course, Veva and I also visited Pasteis de Belem, home of some of the finest pastries I have ever tasted in my life (and blogged on previously, including my poem dedicated to these pastries).

A very fine trip, due primarily to our wonderful hosts. Thanks again, Joao and Carlos!

Two thoughts about the economic meltdown

ONE

One thing about the government bailouts make me happy: for years, our so-called leaders have told us that there simply isn't enough money to pay for universal health care, decent education for our children, repairing our infrastructure...and many other services that would help millions of our own citizens.

Well, now we know that is all bullshit. Because when the banks and financial services companies started to fail, suddenly there is more than enough money to shower on these Titans of Capitalism. And the extraordinary numbers thrown around in this bailout make the cost of things like universal health care seem downright reasonable.

So I say: if we are going to put our children and grandchildren deeply into debt, let's do it in a way that benefits them and not just a handful of fat cats on Wall Street.

TWO

GM, Ford and Chrysler CEOs come to Washington begging for $25B in bailout funds and they are raked over the coals - justifiably. "Where's the plan? How do we know you won't come back for more?" Now, I have mixed feelings about this bailout; these companies are so badly managed. But their collapse will be catastrophic for our economy. At least, however, there was a reasonably public debate over the use of public funds.

But Congress said go away (and come back later with a plan). Oh, and the Bush Admin expressed opposition to giving the Big Three this money.

Days later, after no public debate, no Congressional hearings....Citigroup is handed another $20B of taxpayer dollars. What is their plan, I wonder? How can a company that does nothing but push bytes around in different computers (that's what financial services mostly comes down to, doesn't it?) get a free ride when GM does not?

It's almost as though the Bush Administration is more concerned about making sure rich people stay rich than middle class and poor Americans keep their homes. Huh.

Catching up with old trips

I have uploaded hundreds of photos from trips to Europe and India I have token in the past few years. You can find them all at my flickr site:

http://flickr.com/photos/60694364@N00/

I am sorry that I do not have comments about these photos (some don't even have real names). I hope you can simply enjoy the images....

Time for another vote!

OK, so Barack Obama was elected President of the United States.

THAT MAKES ME SO VERY HAPPY.

I don't expect that he will be able to reverse the decline of the American Empire, but he sure is a sight for sore eyes and ears and brains and conscience. And to think that Americans could see their way to electing a non-white old male to be their President. I am more hopeful than I have been in a long, long time.

Anyway, that election is done with and now I am writing to ask your help for another election: vote for my son, Chris, in a remix competition! Chris sent out this email today, and I pass it on to all of you.

From Chris Silva, http://chrissilva.com

Hello friends, fam and recipients of my spam!

I know many of you may not have heard from me in quite a while since I've been in serious hermit mode and taken a considerable break from the business of visual art and the relentless hustle that is needed to sustain that career. But I'm back and asking for your support in my venture to make music a more solid part of my existence. I have realized that creating music is too important an aspect of who I am and it would be fantastic if it could start bringing in some income at some point too.

So here's where you come in!.

Below is the link to my entry to this Roots "Criminal" remix contest:

http://www.indabamusic.com/submissions/show/3621

So please hook me up with a vote! Just click the link above and press "vote for me" on the page you are redirected to. Then, if I make it to the top 25 then I can actually compete in a real remix competition.

The determination of winners for this first round is really lame (didn't realize this until after the fact)…basically a self-promo battle for votes. I guess the judges didn't want to have to listen to 310 remixes to determine what was actually good. But I worked hard on my track and feel its good enough to be in the top 25, so I'm giving it a shot.

The top 25 finalists will advance to Round 2. For Round 2, The Roots will make another track from Rising Down available to be remixed by the 25 finalists, and thankfully there be 3 judges making the final decision.

Oh, and "L.C. Rivers"...that's me. Lavish Catastrophe Rivers is an anagram of Christopher Tavares Silva and is what I'm using as my music production identity.

Much love to all!

Chris...

Play games to become a better developer

I recently posted two entries on my ToadWorld blog that I thought you might like to see:

Play games to become a better developer!

Software development is one heck of a serious job. It turns out, however, that there are several games you can play to improve the quality of code you write. This is the second of two blog entries that introduce you to two of my favorite brain development and training games: Set and Mastermind. Play either (preferably both) of these games, and you will write better software. [ Note that I do not include Solitaire in this list. Playing this game will definitely not help you become a better developer, but it will pass the time. ]
I even encourage you to play these games on company time, with management approval. It will be a good investment by your employer. Sound crazy? I have been told by a number of my students that their manager did, in fact, agree to do this, and everyone is happy with the results.....

For the full explanations:

Part 1. The Game of Set
Part 2. The Game of Mastermind

Enjoy!

McCain is oh so proud of cute, little Sarah

Is anyone else bothered by McCain's repeated use of the word "proud" to describe how he feels about his vice presidential candidate, Sarah Palin?

As in:

"I'm so proud of the way she ignites the crowds. The way she has conducted herself in my view is incredibly admirable," McCain said.

Let's suppose for a moment that McCain hadn't plucked Palin out of relative obscurity (at the urging of the ultra-right in this country, most notably Rush Limbaugh, who started pushing for her as the GOP VP candidate back in February 2008).

Suppose he had picked Mitt Romney or Rudy Giuliani.

Can you imagine John McCain saying over and over again:

"I'm so proud of Rudy, the way he responded to 9/11."

Doesn't that sound just a wee bit condescending? Like McCain is her dear, old Uncle, patting her on the head?

Doing SQL in PL/SQL: a key resource from Bryn Llewellyn

One of the highlights of Oracle Open World 2008 for me was the presentation by Bryn Llewellyn (PL/SQL Product Manager) on 'Doing SQL in PL/SQL: best and worst practices.'

Bryn surely has the most thorough and clear understanding of the PL/SQL language of anyone I have met (definitely including me).

His talk was detailed and precise (and maybe just a little bit overwhelming. He needed twice the time allotted) on this most important topic.

The bad news about this talk is that most PL/SQL developers will never be able to hear Bryn present it.

The good news is that everything he talks about (and more) may be found in a newly published whitepaper of the same name.

Simply visit the Oracle Technology Network PL/SQL Homepage and click on the hyperlink for that paper.

Notice also that Bryn has published an in-depth whitepaper on SQL injection, a very serious and widespread security risk in many applications.

Quick Tip: Oracle11g function result cache

I just realized it's been a little while since I offered some PL/SQL thoughts on this blog. Sorry, the election campaign is twisting around my priorities. So how about if I share with you what I believe is far and away the most important new feature for PL/SQL developers in Oracle11g: the function result cache.

Suppose you have a table that is queried frequently (let's say thousands of times a minute) but is only updated once or twice an hour. In between those changes, that table is static. Now, most PL/SQL developers have developed a very bad habit: whenever they need to retrieve data they write the necessary SELECT statement directly in their high-level application code. As a result, their application must absorb the overhead of going through the SQL layer in the SGA, over and over again, to get that unchanging data.

If, on the other hand, you put that SELECT statement inside its own function and then define that function as a result cache, magical things happen. Namely, whenever anyone in that database instance calls the function, Oracle first checks to see if anyone has already called the function with the same input values. If so, then the cached return value is returned without running the function body. If the inputs are not found, then the function is executed, the inputs and return data is stored in the cache, and then the data is sent back to the user. The data is never queried more than once from the SQL layer - as long as it hasn't changed. As soon as anyone connected to that instance commits changes to a table on which the cache is dependent, Oracle invalidates the cache, so that the data will have to be re-queried (but just once). You are, as would be expected inside an Oracle database, guaranteed to always see clean, correct data.

Why would you do this? Because the performance improvements are dramatic. In the 11g_emplu.pkg script (available in the demo.zip at PL/SQL Obsession), I compare the performance of a normal database query via a function to a function result cache built around the same query and I see these results:

Execute query each time Elapsed: 5.65 seconds.
Oracle 11g result cache Elapsed: .30 seconds.

Isn't that just amazing and incredible and wonderful? Here's the original version of the function (over 5 seconds):

PACKAGE BODY emplu
IS
FUNCTION onerow (employee_id_in IN employees.employee_id%TYPE)
RETURN employees%ROWTYPE
IS
onerow_rec employees%ROWTYPE;
BEGIN
SELECT *
INTO onerow_rec
FROM employees
WHERE employee_id = employee_id_in;

RETURN onerow_rec;
END onerow;
END emplu;

and here's the result cache version:

PACKAGE BODY emplu
IS
FUNCTION onerow (employee_id_in IN employees.employee_id%TYPE)
RETURN employees%ROWTYPE
RESULT_CACHE RELIES_ON ( employees )
IS
onerow_rec employees%ROWTYPE;
BEGIN
SELECT *
INTO onerow_rec
FROM employees
WHERE employee_id = employee_id_in;

RETURN onerow_rec;
END onerow;
END emplu;

Can you see the difference? Not much of a change, right? I just added that single RESULT_CACHE line. And notice that I would not have to change any of the code that was already calling this function.

Here's the bottom line regarding the function result cache: get ready now to take advantage of this feature. Stop writing SELECT statements directly into your application code. Instead, hide your queries in functions so that you can easily convert to result caches when you upgrade to Oracle11g.

Sarah Palin, the lipstick-coated, pitbull-mannered Stepford Wife

I watched the VP debate. Yep, there is no doubt about it: we now know that if Sarah Palin is given a month to prepare for a debate, then she will not totally screw things up. In fact, what we found is that she will be able to pretty much ignore whatever question is presented to her and instead spit out her pre-programmed statements.

And she will do it in an aggressive, condescending manner that indeed makes one think of a pitbull with lipstick and very nice $400 eyeglasses.

Doggone it, but she reminded me so much of a Stepford Wife. She just didn't seem entirely human.

Well, that does it, then. I will vote for Obama.

Could they at least APOLOGIZE for f#@king up our country?

For years now, people on the left have declared the US economy a "house of cards" built on debt and by transferring wealth from the middle class and poor to the rich. I include myself in this group, as you can verify by reading back through my blog.

And for those same years, the media and our elected officials bowed down to the so-called leaders of our great nation: Alan Greenspan, Warren Buffet, T. Boone Pickens and the other exorbitantly-paid CEOs who steered the great ship of the greatest example of the wonders of capitalism. They could do no wrong, they could not earn enough money, and they bristled whenever anyone talked about maybe giving the middle class a tax cut. ("Class warfare!" went the cry)

And for those same years, we doubters of the wonders of the "free market" have been vilified and mocked. Naive! Communist! Ignorant!

Now, sadly, it must be said: We were right. We of the left, we of the Naive Class, we Americans who never believed that a CEO was worth 500 times the value of a software developer in his company, we bleeding hearts who could never accept that 40 million Americans must have no health care, that tens of millions must go unemployed, that children should go hungry in this country: we were right.

And our so-called leaders were wrong. And not just wrong. Complicit, greedy, corrupt and arrogant.

These days, it is the arrogance that gets me the most.

They are so used to running everything their way, that no one even feels the need, the sense of human decency, to apologize.

Alan Greenspan, who allowed the economy to drift into this horrible state, is no wise man. He is a smart man who knew how to get his bread well buttered. And he does not apologize for his part in this mess.

William Jefferson Clinton, who signed into law deregulation of the financial industry that made this collapse inevitable, is no friend of the people. He is a brilliant politician who always sided with Wall Street. And he does not apologize for his part in this mess.

All those CEOs (from both failed and failing companies), who filled their boards will yes-men and yes-women who agreed to the most obscene pay packages, are not wise men. They are greedy bastards who will not apologize for their parts in this mess.

Keep it up, Leaders of the Free World. Make no apologies, accept no blame and stuff your pockets with every dollar bill (or euro) in sight. Then build some really big walls.

Because if the collapse continues, and if the bailout mainly bails YOU out, then I predict that the American people will shed their sheeps' disguises. They will come boiling out of their homes, full of anger and desperation, and I wonder if any of the walls you build could be tall enough to stop them.
