That's only going to rise - lots of people will end up with a phone, a tablet, and maybe a separate e-reader. This has implications for anyone who thinks we can "easily" reduce power usage as well...

STIC is a forum where Smalltalk professionals, researchers, and enthusiasts can meet and share ideas and experiences. We are currently accepting proposals for talks involving Smalltalk technology and other areas of innovation in the software industry. We're looking forward to an excellent conference, and need your participation to maintain the high technical level of the conference!
The conference will take place in Biloxi, Mississippi, March 19 13 21, 2012.
Presentations will have 45 minutes time slots including discussion. They may be in the form of
We have released the new version 1.7 of Fuel, a binary serialization framework for Pharo that provides extremely fast deserialization. More information on our home page. Again, I thank ESUG for sponsoring me through the SummerTalk program.
You can download this version in Pharo 1.2.1 or 1.3 with:
Today's Smalltalk 4 You looks at the cross platform nature of Pharo (the same things apply to Squeak and VisualWorks - and VA Smalltalk supports source portability).

It's nearly complete - the outstanding work is to integrate JQuery scripting
support - though it's certainly usable in it's current form. Feedback is
welcome.
This week James talks to Niall Ross, a Cincom Smalltalk engineer who was the local representative for this year's (2011) ESUG conference in Edinburgh, Scotland. Niall got involved in just about every aspect of the conference, and that's what the conversation was about.

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.

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:
And here's what we had after the commit:
That pretty much wraps it up for today - we'll look at some more examples next time.

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.

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).

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.

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 :)
