Being Cellfish https://docs.microsoft.com/archive/blogs/cellfish/feed.xml Stuff I wished I've found in some blog (and sometimes did) Wed, 17 Apr 2019 03:21:26 GMT en-US hourly 1 What has happened? https://docs.microsoft.com/archive/blogs/cellfish/what-has-happened Tue, 31 Mar 2015 08:15:00 GMT https://blogs.msdn.microsoft.com/cellfish/2015/03/31/what-has-happened/ I wrote this almost a year ago the day before my last day at Microsoft. You should really head over to my new blog to see what has been happening since then.

]]> When to use Tuples in C# https://docs.microsoft.com/archive/blogs/cellfish/when-to-use-tuples-in-c Tue, 25 Mar 2014 03:25:00 GMT https://blogs.msdn.microsoft.com/cellfish/2014/03/25/when-to-use-tuples-in-c/ I've seen people use the Tuple class in C# code and I've even done it myself once. And I didn't like it. I'm still struggling to see find a case where using a Tuple would actually be a good idea versus the alternatives.

]]> Tail Recursion and C# https://docs.microsoft.com/archive/blogs/cellfish/tail-recursion-and-c Tue, 18 Mar 2014 06:03:00 GMT https://blogs.msdn.microsoft.com/cellfish/2014/03/18/tail-recursion-and-c/ Tail recursion is a powerful optimization since it typically improves both execution time and memory usage for recursive calls. It can also be your enemy if you forget about it.

]]> Logical task combinators https://docs.microsoft.com/archive/blogs/cellfish/logical-task-combinators Tue, 11 Mar 2014 06:11:00 GMT https://blogs.msdn.microsoft.com/cellfish/2014/03/11/logical-task-combinators/ When I had to use Erlang for the very first time it was a brand new language and I was in collage. Back then Erlang did not have a logical not function so we had to define our own in order to make our code readable. At least given the knowledge me and my lab partner had at the time. So the other week I had a deja vu moment since I had a Task<bool> that I wanted to negate. At first it felt real weird and I ended up solving my problem in a different way. But then I started to think.

]]> Hashtable vs ConcurrentDictionary https://docs.microsoft.com/archive/blogs/cellfish/hashtable-vs-concurrentdictionary Tue, 04 Mar 2014 04:03:00 GMT https://blogs.msdn.microsoft.com/cellfish/2014/03/04/hashtable-vs-concurrentdictionary/ Historically I've seen the Hashtable be favored over ConcurrentDictionary with the assumption that is was more efficient allowing for lock free reads. Well they both allow lock free reads so which one is really the better option?

]]> Lunch Dictator or Tweeting from PHP https://docs.microsoft.com/archive/blogs/cellfish/lunch-dictator-or-tweeting-from-php Tue, 24 Dec 2013 06:12:00 GMT https://blogs.msdn.microsoft.com/cellfish/2013/12/24/lunch-dictator-or-tweeting-from-php/ A while back I needed a way to simply post tweets from PHP. To my disappointment most examples I found were about reading tweets or required a bunch of PHP modules I did not have the opportunity to use on the server where the script was going to run. So I had to do some work.

]]> 429 vs 503 https://docs.microsoft.com/archive/blogs/cellfish/429-vs-503 Tue, 17 Dec 2013 05:12:00 GMT https://blogs.msdn.microsoft.com/cellfish/2013/12/17/429-vs-503/ A while back I was involved in a discussion around using 429 instead of 503 in order to tell clients they should back off a little. And there are some good arguments for both. Here are my thoughts.

]]> Abstracting time https://docs.microsoft.com/archive/blogs/cellfish/abstracting-time Tue, 10 Dec 2013 10:12:00 GMT https://blogs.msdn.microsoft.com/cellfish/2013/12/10/abstracting-time/ Probably one of the most common tight couplings I see is a dependency on system time, i.e. using DateTime.Now or DateTime.UtcNow directly in your code without any abstraction around it. A tight coupling that typically leads to very complex and fragile tests when trying to ad test coverage.

Given that it started 3am local time when New Zeeland first launched it has been an interesting and long day.
