Weekly Recap
Unfortunately, I am *extremely* behind on my normal content creation this week… I will be trying to write articles this weekend to backdate some of the days I missed this week, but overall this was quite a miss for me with respect to normal publishing.
UNEXPECTED 87% Performance Boost! – C# Collection Initializers
In C#, we have multiple ways that we can create collections. We have collection initializers in C# as well as collection expressions in C# – both of which create new collections with items in them.
But have you ever wondered about the performance of these two? Let’s use BenchmarkDotNet to performance profile our C# code and see if collection expressions have different behavior!
Starting Your New Software Engineering Role – Engineering Manager AMA
This AMA was based on the topics discussed in my newsletter:
– Sorry, LeetCode won’t save you now
– The best answers for career progress: your manager
– You’re in the driver’s seat of your career
– Non-tech skills are more important than you imagine
C# Regex On EASY Mode – 3 Beginner Examples
Have you used regular expressions in C#? If not, no worries! This is the perfect beginner primer to get you started using regex in C#!
Regular expressions allow us to do more complex string pattern matching. This means that we’re able to do more advanced variations of the basic C# string checks like StartsWith and EndsWith! Check out these beginner regex examples in CSharp!
Software Engineers Need… BRANDING?! – Interview With Anna Miller
I bet you never thought as a software engineer you were going to hear that branding was important, right?! After all, isn’t that what the marketing team is for? Isn’t that kind of a “salesy” thing?
And you’re exactly right — as a software engineer, your brand and the branding that you create can be immensely valuable for the relationships you form inside AND outside of work. In this video, I speak with Anna Miller and we get to hear all of her awesome perspectives on branding for software engineers.
OVER 800x IMPROVEMENT?! Benchmarking Regular Expressions in C#
NOTE: there was a critical flaw pointed out in these benchmarks and I’ll have a follow up article posted on Sunday and a video to YouTube on Monday explaining the situation.
Look, it’s not clickbait. If you check out these benchmarks, you’ll see a scenario that you might be doing in your very own code and you could be getting an 800x performance boost. And if you think there’s no way you have a Regex in C# that will speed up by 800x, then you might see another benchmark where you could get a 100x gain!
In this video, I walk through the various ways that you can construct a regular expression in C# and the different performance characteristics of each. While this isn’t an exhaustive benchmarking collection over a wide variety of C# regexes, hopefully, this serves as some inspiration to benchmark your code!
C# Regex Performance: How To Squeeze Out Performance
Regular expressions are powerful for pattern matching, but what about performance? Check out this article for details on C# regex performance from benchmarks. NOTE: as mentioned above for the YouTube video, there will be follow-up content for the inaccuracies in this article.
As always, thanks so much for your support! I hope you enjoyed this issue, and I’ll see you next week.
