I think I visit this guy's page at least once a week to copy-and-paste a little PowerShell snippet that generates a GUID.

Write-Host ([System.Guid]::NewGuid())

You'd think that after the first ten times, I would start to memorize it. I guess when I need a GUID, I'm very far away (mentally) from thinking about the PowerShell syntax.

Harumph.

...or two.

I've had two projects this week where their/my bacon was saved by the branching strategy used for the source code repository. In my line of work, I touch a wide variety of projects. Some are still shiny new and others were written years ago; they're all in a source control repository.

Modern source control repositories (and by modern, I mean things that are not your file server or P:\ drive) let you create a branch. Branching might appear complex at first, but it's really pretty simple - at least conceptually. Here's a little story to illustrate the point of branches.

When I create a branch, I have a snapshot of the code at a particular point in time. So, imagine that on Monday, I have a single branch called the "trunk". It contains all of the code for my web site. On Tuesday, I created a branch based on the code in the trunk. I named my branch "BR-1". When I created BR-1, it was a mirror image of the trunk. I edited the code in BR-1 for a couple of days and nearly got it how I wanted it. My edits were isolated to BR-1 and they did not exist in the trunk.

I got a call early on Friday morning about an important change that needed to go out right away. I couldn't implement the urgent change to BR-1 because it contained my partially completed work. It was a pretty small change; a few hours of brilliant coding and I would be ready for a peer review of my changes. So, I checked out the trunk and made the edit right there and checked it back in. I published the urgent change I made on the trunk out to the live web site in the early afternoon and went back to working on BR-1.

By mid-day on the following Monday, I had finished all of my changes to the BR-1 branch. I had merged the BR-1 code into the trunk too. Now my trunk code contained the changes from BR-1 as well as that urgent change that came through on Friday morning. Complete control with the flick of a switch.

In the previous story, I was able to handle the urgent request efficiently because I used branching to manage my code changes. If I didn't have branching available as a software development tool, I would have some bad choices to make. Either I merge the urgent fix with my own enhancements and risk problems by rushing it, or force the urgent change to wait until my own changes were done; neither are necessary.

Branching is great way to ensure that I can always put my work on the shelf in lieu of more pressing matters. Understanding the concepts of branching is essential to being a valuable member of the team. The keys you actually press to make a branch or merge two branches can be left up to the nerdy folk.

swollenface Yep, that's my head as of last weekend. I had my two remaining wisdom teeth extracted by Dr. Bell at the Head & Neck Surgical Associates in NW Portland, Oregon. Le Wife says it got a little larger than this at the peak on Sunday morning.

I had the other two extracted in my twenties back in Chicago; a truly horrible experience. I was naive for picking a dentist arbitrarily from a listing and this particular dentist was an idiot for trying to do it. He said he could take all four out without much of a problem. I hadn't gone to a dentist in years and it seemed like a reasonable thing to do; I was in my twenties, so it was time to get the wisdom teeth removed. After multiple hours of pain and agony, he removed 1.5 teeth out of four total. He packed me full of gauze and handed me the address of a surgeon. I drove my corvette to the other office and the surgeon finished taking out the second tooth in about five minutes.

So, I waited about ten years or so on removing the other two. When the Wife and I moved to Portland, we found our dentist, Dr. Halvorsen, right away via referral from a friend and we've been keeping up reasonably well with six month cleanings.

At my last cleaning, I decided to have the final two teeth removed. I knew it would take some time to recoup and the baby is coming in late April, so I made plans to have the procedure in early January and be done with it. They recommended Dr. Bell's office for some super impacted wisdom teeth.

Dr. Bell and his staff did and outstanding job. I had a consultation and scheduled the procedure for about two weeks later. They were friendly and efficient. I arrived at the office, got into the chair, chatted with the nurses, got prepped with an IV, received some drugs, and was sitting back in my car in about 60 minutes total. I nearly didn't believe him when Dr. Bell said the entire procedure would last between 60 and 90 minutes during an earlier consultation.

I *felt* like I could drive home, and the Wife just laughed. I knew I couldn't but the drugs didn't make me feel wobbly or anything, they just targeted the pain.

That night I was back on the computer working on some code. I was prescribed some oxycodone and ibuprofen for the pain and swelling and thankfully, it didn't interrupt my coding much; albeit I might have been a little slower and more *creative*.

The pills worked good as long as I kept my belly full of food. I found out that I got nauseous if I didn't eat enough food with the pills and/or I would get an stomach ulcer feeling. After I figured that out, it was much better. I probably can't go to the gym for another two or three weeks, so this isn't going to help my gut much.

Yet, I'm glad I timed the procedure with the MLK holiday because this past week stinks with pain management and thinking really hard about code. I think I only snapped with cranky responses a few times during the four day work week. :) Its much better to work alone when you're in pain. I figure another couple of weeks I'll be good as new, er... good as a thirty-four year old new guy.

Portland Trail Blazers Le Wife and I have tickets to some Portland Trail Blazer games this year. Last night was the first one we attended this season. It just so happened to be an opportunity to keep the streak going and make it ten wins in a row.

As a gesture of respect, I dropped Le Wife (who is now 21 months weeks pregnant) off right in front of the stadium and I parked the car. That was harder than I anticipated. I guess thousands of people congregating on a single place do tend to make traffic and parking more difficult.

Word to the wise — parking in the under the Oregon Convention Center for $6 and walking 200 yards north is very handy. Its deceptively close; walking under I–5 makes it seem farther than it really is. Plus, this lot wasn't crowded 20 minutes before tip off. I might think twice about parking there in a pouring rain, but it was a pleasant walk for me; a nice brisk evening.

The game went right down to the wire with neither team making it farther than 8 points ahead (if they did, it wasn't for very long). In the end, our guys managed to hold off Allen Iverson and Carmelo Anthony to make it ten wins in a row. The packed stadium was booming, I'm looking forward to the next game!

At one point the crowd started cheering really loud — just before the end of half time. Up on the big screen above center court was a live shot of Greg Oden sitting behind the Blazers' bench in a sport jacket and white button up shirt. He didn't see the camera and looked around quickly to see the cause of the cheers. Then he looked up at the screen above center court and realized what was going on. He grinned wide and looked down at the ground in the biggest "aw-shucks" moment I've seen in quite a while. Portland is going to love seeing this guy on the court next year!

sergio-rodriguezAnd perhaps the biggest boon of the game — bobble-head night! I am now the proud owner of a Sergio Rodriguez bobble-head doll. There's a bright warning on the side of the packaging:

LINQ is an acronym for Language-Integrated Query and a new feature in v3.5 of the .Net Framework from Microsoft. This new version of Microsoft .Net reached RTM status a couple of weeks ago — this framework is chock full of brilliant things I can use to improve my efficiency and effectiveness on daily tasks here at Pop Art.

As one of my favorite features, LINQ helps me write data-driven application even faster than what .Net 2.0 brought to the table. A common example starts with launching Visual Studio 2008. After dragging a collection of tables from a SQL Server database onto a surface in my solution, I can see a visualization of the columns in the tables as well as the relationships between them. Click the following thumbnail to see a larger image.

database schema

Next, I start writing data access code directly in my C# program as opposed to switching languages and writing in the T-SQL language. Visual Studio gives me Intellisense here too; as I type the name of a table and click the period key, all of the columns in the table appear where the cursor is located. Big time saver. Huge! I'm certain that I didn't misspell a column name and that my code will compile.

intellisense is beautiful

The syntax for LINQ in a C# program is very similar to the T-SQL language, which is a "set based" language. LINQ statements are compiled, just like the rest of my C# code. The first thing someone well versed in T-SQL will notice is that the columns normally specified in a SELECT query are at the end of the LINQ statement instead of the start as in T-SQL. The idea is that you're articulating your constraints at the start of the LINQ statement and then pulling out the fields you need at the very end.

a LINQ sample

Behind the scenes, LINQ is using the relationships expressed in the database to generate T-SQL scripts on the fly. This is a clear line of demarcation for LINQ. If you're using stored procedures exclusively for database access, then LINQ isn't going to buy you much. You'll still get Intellisense inside Visual Studio and you can specify an existing stored procedure instead of using the auto-generated SQL, but you're giving up a lot of acceleration tools. Perhaps more than you're getting in return.

LINQ really shines in multiple table joins and aggregation. The following two blocks of code show a query is performed in LINQ and its equivalent T-SQL script. The query retrieves product information from three tables where the list price is below a given amount and a sub-category name exists. If you go the T-SQL route, you will still need to write some C# code to call your database query.

Which of the following versions would you rather author and support?

LINQ Version

a more complex LINQ statement

T-SQL Version

an equivalent T-SQL statement

MSDN is a great online resource for developers and they really hit a home-run here. They have a page with 101 LINQ samples. This is my preferred way to learn when I already know the surrounding technologies and I want to fill in a specific gap. The page categorizes several ways of retrieving and iterating over information.

mocha master I think you're a good person, but I can't be with you. I have to break up. Sure 2007 was a fun year, galloping around the estate with that thick scent of delicious coffee in our hair and eager for the new dawn of a dark roast. We had some good times. The Techni Vorm label made me feel European too and I tried to embrace it, I really did. Its not you, its me.

virtuoso It wasn't easy with your friend, Virtuoso, the coffee grinder. He never made it simple for us. I don't think he ever really accepted me. What was up with that static electricity? It let forth a brilliant shower of charged coffee grounds after each use. I'm mean really, how can he expect to keep someone around? Sure his sleek exterior and large bean reservoir would make anyone grin, but I've got to think of myself sometimes, I have to ask, what's in this for me? It was just too much of a mess to clean up after every grinding session.

Mocha Master, why did you start spilling over? At first, I was willing to blame it on the other people you saw. There were several accounts sent around on how to properly make coffee. But time and time again, you spilled when no one was looking. The final straw was when you spilled yesterday for me. It was me Mocha Master! I was here all alone with you and yet you forsake me. How could you do it? You know the level of coffee grounds in there was well within the accepted norms. Somehow you clogged up and spilled over the counter just like all of the times before. I have to give you up.


mr coffee Hello Mr. Coffee, its been a while. I know I've been a bad friend and traipsing all over the coffee producing regions of the globe with my European friend, but its over, I swear.

I see you've gotten some new buttons and they look great, all shiny and in different colors. I've even started using a carafe so you don't need to worry about burning the coffee and ruining the flavor.

starbucks grinder Oh, and hello little grinder! How have you been? I sure do miss you. Sure, you're from Starbucks, but that's ok. You're a good little guy and you don't have any static electricity. We love large machines and small machines alike. Sometimes you're abused and blamed for a mess, but its far and few between and I know you mean well. You can't fight gravity! Plus, you can grind your beans in 10 seconds flat. I'm going to enjoy seeing you around.

Mr. Coffee, I want you to know that I'm ready to get down to work and you won't have to worry about any more whimsical adventures from me. We have a simple agreement in place; you make coffee and I'll drink it. We don't need any drama in our lives around this matter and neither of us wants a high maintenance relationship. I'm glad you were willing to come back. I love you Mr. Coffee.

I was fortunate enough to pop up to a special event on Silverlight at Microsoft in Redmond, WA today. Mithun Dhar, Laurence Moroney, Arturo Toledo, Adam Kinney, Ernie Booth and Jesse Liberty gave us some sweet tips on building apps and organizing a good workflow between developers and designers.

Arturo is an awesome graphical designer. Oddly, or perhaps not, I liked his presentation the best. He made the Expression products fly and gave me (a developer) good tips on working efficiently with my design team. Jesse was a close second with his fundamentals presentation - he really clicks well with developers.

The crowd was mixed with about 60% developers and 40% graphic artists. I saw the ScottGu blog post this morning announcing that Silverlight 1.1 is now named Silverlight 2.0 - between that and the hints dropped at today's meeting, it feels like Silverlight is getting ready to explode. I think I'll still remember this day very well in three to five years.

I got a favorable message, so I reckon its not all that bad.

After all, Rocky got an 84. I think I rocked most of the ASP.Net questions, but the smart client stuff and multi-threading is a little foreign to me.

What did you get?
