Why Do Modern Buildings Look Awful?

October 23, 2011 19:43:15.363

It seems that in a very real way, many architects see the world differently than the rest of us do:

There are many such confirming studies. For example, Gifford et al. (2002) surveyed other research and noted that “architects did not merely disagree with laypersons about the aesthetic qualities of buildings, they were unable to predict how laypersons would assess buildings, even when they were explicitly asked to do so.” The researchers traced this disagreement to well-known cognitive differences in the two populations: “Evidence that certain cognitive properties are related to building preference [was] found.”

I wonder if this has now reached the self selection stage where the problem is reinforcing itself....

A Dance With Dragons

October 22, 2011 19:15:24.687

I just finished A Dance with Dragons: A Song of Ice and Fire: Book Five - and as per usual, he's thrown a few curveballs at us. Here we are in book five, and we are still being introduced to new characters. There's also a shocking (to me, at least) death near the end of the book - someone who I was sure was going to be a player all the way to the end bought the farm.

I'm still not pleased with what he's doing with Arya - I'd like to see her come back into the main story somehow. At least Tyrion is still a major player - I like that character quite a bit, and he keeps managing to land on his feet (although I'm curious to see how the deal he makes towards the end of this book plays out; his cards seem really weak at this point.

My one complaint was that the book was hard to get back into. Like the Wheel of Time books, the gap between installments has just been too long, and by the time a new one comes along, I've forgotten where the story was. At least winter has finally arrived :)

DLC For Deus Ex?

October 19, 2011 22:36:28.619

I'm a bit skeptical - the game has a defined beginning, middle and end - so I'm skeptical about how well DLC will fit into the narrative. Still, I liked the game, and the DLC is supposed to slot in during a failry obvious interstitial in the game. I downloaded the DLC while I was visiting my sister; we'll see how it goes :)

ST 4U 147: Using SQL Directly with VA Smalltalk

October 19, 2011 8:54:10.736

Today's Smalltalk 4 You looks at direct SQL access from VA Smalltalk. It's pretty simple, so long as you remember that the API differs when you use select (as opposed to any other SQL operator). If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

SQL Access.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at accessing a relational database using direct SQL statements in VA Smalltalk - to see how to connect, please go back to this tutorial, as we are building on it here. You'll want to take a look at class AbtQuerySpec if you intend to work at this level with your database accessing. The main thing to know is this: if you are querying (using select), then you use #resultTableFromQuerySpec: If you are using any other kind of SQL statement, use #executeQuerySpec: instead. The way you utilize this is pretty simple. To query, use the following kind of code:


"using AbtQuerySpec"
resultCollection := OrderedCollection new.
querySpec := AbtQuerySpec new.
querySpec statement: 'select * from people'.
result := connection resultTableFromQuerySpec: querySpec.
result do: [:eachRow | resultCollection add: (eachRow)].
^resultCollection.

It will look the same with a where clause:


"with a where clause"
resultCollection := OrderedCollection new.
querySpec := AbtQuerySpec new.
querySpec statement: 'select * from people where zipcode = 12345'.
result := connection resultTableFromQuerySpec: querySpec.
result do: [:eachRow | resultCollection add: (eachRow)].
^resultCollection first asDictionary

To use any other SQL statement:


"insert with a query spec"
querySpec := AbtQuerySpec new.
querySpec statement: 'insert into people values (''Fred Flintstone'', ''Rubble Way'', ''Old Town'', ''PH'', 23456, ''456-7890-1234'')'.
connection executeQuerySpec: querySpec.

"commit it"
connection commitUnitOfWork

"delete with a query spec"
querySpec := AbtQuerySpec new.
querySpec statement: 'delete from people where zipcode = 23456'.
connection executeQuerySpec: querySpec.

"commit it"
connection commitUnitOfWork

That pretty much wraps it up for today - we'll look at some more examples next time.

Sometimes the Journey Stinks

October 18, 2011 3:59:23.111

When you travel as much as I do, you're bound to hit bad weather every so often - and tonight I hit the jackpot. A line of storms diverted us to Houston for fuel, and then a second line kept us circling DFW for a bit. Then I had to wait in a long line at Avis - I hadn't updated my card with them, so even though I was on the "Preferred" board, I had to go talk to them.

One of those days....

ST 4U 146: Deleting from a Table using VA Smalltalk

October 17, 2011 8:21:56.897

Today's Smalltalk 4 You looks at deleting rows from a database using VA Smalltalk. We'll look at the "object" level interface to that today, and get to general use of SQL in a future screencast. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Delete.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at deleting data from a database using VA Smalltalk - to see how to connect, please go back to this tutorial, as we are building on it here. You can do this sort of thing directly via SQL, and we'll be getting to that in another screencast. Today we'll be looking at the "object" interface for this.

Once you have a connection to your database set up (with a user who has permissions to make changes), you can delete data pretty easily. First, query the data out of the database:


"delete a row"
table := connection openTableNamed: 'PEOPLE'.
querySpec := (AbtQuerySpec new)
	statement: 'SELECT * from PEOPLE where PEOPLE.ZIPCODE = 12345';
	hostVarsShape: (nil).
rowToDelete := (connection resultTableFromQuerySpec: querySpec) first.
table deleteRow: rowToDelete.

Next, commit the work:

"commit it" connection commitUnitOfWork

Now, before we executed the delet, here's what we had from the query:

queried data

And here's what we had after the commit:

queried data

That pretty much wraps it up for today - we'll look at some more examples next time.
