Retry Policy in C# for dotnet core

I just published a new article on Code Project with the full source code. How to create and use a Retry Policy utility class to add some resilience to your dotnet projects. This will help in situations where a temporary network or disk failure might cause a transient error in an app. https://www.codeproject.com/Articles/1273180/Retry-Policy

Why do I still teach?

Why do I still teach after 20 years?

At some point we all ask our selves, “Why am I still teaching?” I have guided many students to their black belts, helped them achieve their self-defense goals, and aided their successes at the national level. Neither is the reason.

I have been working with a student affected by certain physical ailments which diminish her coordination and strength. She also has self-esteem issues. She is physically incapable of performing some of the most basic techniques due to her condition. Regardless of her issues I hold her to the same standard as all other students, within reason. She struggled for many weeks to learn her form and earn a Kata patch. Every day after class her father asked if she could perform her poomse to earn the patch. Every day we made corrections to the pattern, stances, hand positions, etc.

Last week she performed her form again and stared at me in suspense as she awaited my response. She performed her form perfectly. I awarded her the patch and her square mouth morphed into a beaming smile. She jumped screaming with joy and pride. She faced her father and in a yelled in a high pitch, “Daddy I got my patch!” That moment is the reason I teach.

She said, “Thank you sensei for giving me the patch”. I made it clear to her she earned the patch through her hard work and determination. I didn’t give her the patch, she earned it. I simply provided the material. She left the gym glowing and walking ten feet tall.

People ask, “When will you stop teaching?” My response, “When my hour of departure arrives.”

jQuery Error 80020101: A fix

I ran into the annoying Could not complete the operation due to error 80020101 bug today. I clearly am not the only one (Google: Could not complete the operation due to error 80020101). This was an old bug in jQuery that was squashed and apparently is back in jQuery 1.7.2 except it isn’t back.
The original bug was related to HTML comments. This was not the cause in my case. It was a query string variable. The fix is simple, take out the query string from the URL.

Change it from this

/Reports.aspx?ReportID=24

to this

/Reports.aspx

EDIT: Alternate Solution

Bruno commented below he this fix was not applicable in his situation. In his case, he needs the querystring. To that end, here is a way to eliminate the issue with a little bit of JavaScript.

You can leave the query string intact and remove it from the webservice URL before making the webservice call with a little bit of javascript. Before calling the webservice, use the following JavaScript to clean the URL and prevent the error

var url = window.location.href.replace(window.location.search, '');

Voilà!
No more Could not complete the operation due to error 80020101

LTRIM RTRIM don’t always work –UDF (UPDATED)

I previously posted on the LTRIM and RTRIM inability to remove certain not printing whitespace characters which can sometimes cause problems. I have updated the SQL page with a User Defined Function (UDF) which can be used in queries or in a stored procedure. I have also included a link to the Code Project article.

LTRIM RTRIM don’t work

LTRIM and RTRIM does not work sometimes if the whitespace character is not actually character ASCII 32. This stumped me for a while. The data entry screen used to enter the information somehow allows users to enter other white space characters other than the regular space from the space bar. It could be related to the system encoding, I don’t know. Here is the code I used to fix the LTRIM and RTRM.
