C# Ternary Operator with no "Else"
Here's a little C# hack I'd like to share, might be really useful to other devs too since it's a very common pain in all languages, not just .NET.

The .NET Framework's built-in WebClient class does not have a built-in timeout feature.
Sometimes you need to "log out other user sessions". To prevent cookie replay attacks or - a very common use case - log out other sessions when a user changes their password. ASP.NET does not have a built-in way of doing this, but there's a simple solution.
TL;DR I spent the last month testing how CloudFlare affects my organic traffic by turning it off and on again™ and measuring the ranking changes. Looks like CF hurts SEO. So we've built our own caching proxy with blackjack and hookers AWS and nginx, while saving a couple of hundred $ a month on the way.
This post has nothing to do with tech nor startups. Today, while adding proper "right-to-left" support to our app UI (for Hebrew and Arabic languages) I got a little carried away and found myself discovering a lot about Aramaic languages and ancient numeric systems.
If you're using OutputCache directive like this:
[OutputCache(Duration = 600, VaryByParam = "*", Location = OutputCacheLocation.Server)]
Or storing custom data in HttpRuntime.Cache like this
HttpRuntime.Cache.Add(...)
You probably caught yourself wondering
If you search for "generate zip in ASP.NET/C#" you get tons of blog posts and StackOverflow answers suggesting DotNetZip, SharpZipLib and other 3rd party archiving libraries. And up until now that was the only solution - all because .NET had no built-in support for zip format.
I've been a happy MacBook user for almost 14 years. Tried all of them - from a tiny 11" MacBook Air to the enormous 17" Pro - and in 2014 I finally ended up with the 15-inch retina model.
The best laptop I ever owned.
Even if you need to occasionally run Windows for work - MBP is still the best possible hardware to do that. The 15-inch retina MacBook had that unique blend or elegance, power, durability... And by "durability" I mean I fell off a motorcycle with this thing in my backpack - not once, not twice, but thrice.
So you're starting a bootstrapped web-based business and you're deciding on the tech stack. After running a software startup with zero funding for 13 years, here's what I have to say about this.
I see a lot of websites and apps using "box-shadow" like this box-shadow: 0px 0px 20px 5px #ddd. Which literally means "lets have a #ddd-colored shadow, with zero offset, 5 pixels wide and 20 pixels blurred".
Which is perfectly fine, for the most part.
