What Actually Happens When You Request An Expedited Review From Apple?

Wednesday, March 16, 2016

I have a client with a Xamarin Forms app that streams live video for sporting events that they host throughout the year. Recently they sent me an email apologizing but saying they forgot to update a sponsor’s logo for an upcoming event. The event was 2 days away, could we get the app updated and in the stores?

I told them the truth. Most likely, no, but we can try. Here is the timeline of how we made it happen.

The white paper discusses the pros and cons of each platform as well as the performance metrics we saw from each when hitting the same Azure back end.

Check For SQL Authentication Type Before Adding Users

Monday, February 10, 2014
sql

While setting up a new team member to run a WPF app locally we ran into an error. It look about 30 minutes to realize our setup SQL script was creating a user in SQL server, but mixed mode authentication was not turned on.

To prevent having to relearn this problem again in the future we’ve added this code to our SQL script, right before the CREATE LOGIN command.

Manually Rolling Back A WPF ClickOnce Application

Friday, February 7, 2014

If you need to revert to a previous ClickOnce version you are expected to redeploy that older version.

Recently I was in a situation where this wouldn’t work as there were checked in code changes that the environment was not ready for. Now I could have reverted to the previous version in TFS and then redeployed that. But luckily I found an easier way.

Here is my solution to the latest code contest from The Daily WTF Programming Praxis: Josephus’ Circle.

What I like about this solution is that it represents in code, how the problem is actually carried out in real life. The soldiers are counted off one by one.

Performance Penalty Of Recursive Calls

Monday, July 27, 2009

This recent post on The DailyWTF has brought in many comments with people providing code samples in many different languages. The post, Programming Praxis: Russian Peasant Multiplication, offers a simple coding challenge.

The challenge screams for recursion and many of the answers in the comments went this route. Of course, when we talk recursion we always have to qualify it as saying there is a performance penalty for using recursion.

Using this Russian Multiplication challenge as an example, I’ve done some testing to see how much the penalty is.

Use VB's Powerful Format Function Through ASP

Wednesday, May 16, 2001

This article originally appeared on 4GuysFromRolla.com at www.4guysfromrolla.com/webtech/051601-1.shtml.

When creating ASP pages you can choose to use a number of scripting languages, such as VBScript, JScript, PerlScript, and even Python. While this may seem all fine and good, realize that VBScript, the most popular server-side scripting languages, is a watered-down version of VisualBasic. Think of VBScript as VB-Lite - certain things are missing.
