Greg Young coins ‘CQRS’, immediately calls it an anti-pattern

Coding standards are bad aka learning the wrong lession

So, Rocky reflected on coding standards, and ended up here: This was the point where I had my first professional developer epiphany. Yes, it is truly painful to adapt to the idea of living within strict coding and style guidelines. But the alternative is so much worse! Ever since that experience I insist on consistency of coding standards and styles within each project (or enterprise) where I work. And even if I think some choices (like 2 spaces after each tab) are really, really, really stupid, I'll use and vehemently support that choice. Um, no. There...

C# Programming in Excel: To delete a worksheet, make it visible

Is programming in Excel better or worse than programming Sharepoint? Anyhoo, I was trying to merge 5 single worksheet excel spreadsheets into a new spreadsheet, and then deleting the blank worksheet created when you create the new spreadsheet. But when calling delete on it, I would get one of those fantastic COM errors you get when programming like it’s 1989.  I tried many different things before realizing: app.Visible = true; would do the trick (I made it invisible because it is a server side process). Fantastic.

Visual Studio 2015 Extensions and Updates Install ‘Bug’

You need to open Visual Studio 2015 in order to get to Extensions and Updates, to update any updated extensions or updates. 37% (unscientifically made up number) of the time, it tells you that you have to shut down Visual Studio in order to continue.  Not ‘you may need to restart Visual Studio afterwards for the update to take effect’ (which does happen sometimes as well), but that you have to.  This, of course, makes no sense. Especially if the Extension only applies to Visual Studio 2015, and it says you have to close down any open instances...

OleDbDataAdapter and Excel: Why are some of the column values missing?

Ran into this recently, writing it down in case I forget. I had an excel spreadsheet that I had been importing for quite a while (meaning, a job that had been working for months on daily submitted spreadsheets) and I wanted to add new columns that were present, so I did all the necessary c# work, but then when I ran the updated project, the values were blank, though I verified they were present in the spreadsheet. It turns out to be related to the fact that the columns were sparsely populated and how the connection string was...

EF 6 Bug – Can’t share tables across edmx files?

I’m trying to upgrade an application from EF 4 to EF 6 and ran into a number of problems, so I spiked out a simple console app and am seeing the same bizarre behavior. Using two different .edmx files, using different connection settings, and using custom namespaces, if I try to have each one reference the same two tables, so that they could have those mapped as entities in each namespace, it fails.  If I run custom tool on the model .tt file one by one, I can see that it will ‘steal’ the entities back and...

Review: Tekpub Webcast - Full Throttle : TDD with Brad Wilson

So, after going through the signup process, I finally gained access to this episode.  Leading up to this review, I have watched the episode in total 3 times:  the first time I watched straight through while taking quick short hand notes, the second time, I watched portions of it in succession, stopping to take more in-depth notes, the third time, I watched it to fine-tune my comments on specific sections. Since I’ve been ragging on Tekpub, it is only fair to start off with a positive general note. Tekpub’s Production Quality Rob has been doing...

Does anyone actually do TDD?

Obviously, the answer is yes.  The person who first convinced me that “all that agile stuff” was really the direction to look towards (note, that’s “a direction to look towards”, not “embrace uncritically”, but I digress) practiced it.  Or at least, he always had his NUnit test runner up, and I could tell when he was too busy to chat by looking at the status of his tests (when they were all green, I figured he was probably goofing off). I ask the rhetorical question though based on the lead to one of Rob’s posts: “One thing I've...

Software Development Troubleshooting Tip #2: When dealing with a large organization

This actually applies to migrations as well. I’ll leave ‘large organization’ vague…let’s make up a number and say if your entire software team (including developers, testers and support personnel) is greater than 20, it qualifies. I’ve seen some organizations do this well, and others…not so much. If you have a critical production issue, you should have two separate call lines, one dedicated to upper management, and the other dedicated to the people actually trying to fix the problem.  One person should be available on both lines, all others should be kept separate. The reason for this...

We have 3 seconds to capture a user’s attention on a new visit – that’s it. If you make them page they will leave, and it’s amazing how many applications still use this dated way of showing information.” Though he doesn’t specify it, he’s obviously talking about (among other things), Google.  An entire industry...

You can get it from here, though unfortunately, to get it, you have to register.  Hate that.  You can also pay to buy a physical copy of it.

The kingdom of Nouns

An attack against OOP (or how Java and C# do it anyway).  Regardless of whether I agree with all of it, the nursery rhyme is worth the read itself: http://steve-yegge.blogspot.com/2006/03/execution-in-kingdom-of-nouns.html

Interesting article.  Can't say I agree with a lot of it, but it reminds me of people I've worked with: http://charlespetzold.com/etc/DoesVisualStudioRotTheMind.html
