  • jQuery Character Table

    The other day I was looking for the HTML code for the ⌘ (in case you can't see it, that's the command key symbol), found in mac keyboards. It was not the first time I was looking for the HTML code for one of those funky characters. I remember having a hard time trying to represent some Math symbols...

  • One less diacritical mark to annoy me

    Being a Portuguese-speaking person living in the US, one of the things you have to get used to is the keyboard physical layout and key mappings. You know, Latin-originated languages tend to have thôse wéìrd chãraçtërs , which are really just diacritical marks applied to regular...

  • Presentation Remote

    In the last few months I have been using my MacBook to give presentation, both at work and not. I've been meaning to buy one of those presenter remotes. I even got to borrow one and tried it once and I must say it worked pretty well. Then I remembered that the MacBook came with that useless remote...

  • Reusing Views in ASP.NET MVC for Ajax Updates

    The other day I came across this post in Marteen Balliauw's blog where he demonstrates and interesting way to make the same ASP.NET MVC view render correctly from both a regular request and an Ajax request. In Marteen's post he uses a custom ActionFilterAttribute to detect the Ajax call and replace...

  • Please open my .aspx fast

    Still in the topic of performance, I'll throw a little freebie. Visual Studio seems to take an inordinate amount of time to open .aspx files for the first time. I noticed that the status bar read "Initializing toolbox..." for a long time. I'm mentioning .aspx but it really applies to...

  • Sluggish Windows in VMWare Fusion - Solved

    I've had my MacBook for over 2 years. Initially I avoided installing virtualization or even BootCamp to run Windows. I was forcing myself to adapt to OS X, get out of my comfort zone, and learn more about that different environment. The mac was also my Ruby On Rails development machine and I wanted...

  • TIP - Disable full row selection in Vista's Explorer

    I've been using Vista since the official release (skipped the betas) and I've been trying to convince myself that some of the changes were made for the better. In particular, I've made some effort to get used to the new file explorer but somethings have been harder to put up with. Anyway...

  • The bug that almost drove me mad, and it's not my bug

    No bug in Windows (XP and 2003) has annoyed me more than the one I just learned how to get rid of. For no discernible reason, while using the Windows Explorer the treeview on the left would just go bananas and display multiple Desktop icons. As seen in the following image. The additional Desktop icons...

  • Tip: export to CSV using ADO.NET

    A friend of mine was telling me about a bug he found in one of his applications caused by a simple lack of escaping quotes when producing CSV files. It immediately reminded me of an old trick in .NET. If you really want, you can create CSV files using ADO.NET and OLE-DB (or ODBC.) I wouldn't necessarily...

  • Software I can't work without

    I'm about to configure a new development machine this week. It's going to be my 3rd install from scratch in the last 12 months, which I know is not all that much, but certainly more than I wish I had to. Besides the common software development tools, like Visual Studio, SQL Server, Ruby, Office...

  • It's obvious, use TimeSpans to measure time

    I know, this is probably not news to anyone. TimeSpan is the native .NET type to represent time intervals. But answer quickly, SqlCommand.CommandTimeout represents the interval in milliseconds, seconds, or minutes? What about System.Timers.Timer.Interval ? To circumvent this situation we see all sorts...

  • UdtTypeName and .NET data types in SQL

    We are working on SQL 2008 for a new project with the intent to leverage the new data types , in this case especially the HIERARCHYID data type. One of the stored procedures we created had a parameter of type HIERARCHYID . The code that calls the stored procedure was something like this. SqlHierarchyId...

  • Excel is the business format, automate it

    One thing I realized when working in large companies is that Excel is the true data exchange file format. That what the business types exchange among themselves and how they like to persist any kind of lists or anything that needs to be formatted like a table (be it tabular data or not.) All too often...

  • Coding style per project

    A few months ago, when I installed Visual Studio 2008 on my system, I opened one of my projects, did the usual project conversion, edited some files, created a few others, saved, tested, and checked in source control. Another developer working on the same project, also with VS2008, later edited some...
