You can become a serverless blackbelt. Enrol to my 4-week online workshop Production-Ready Serverless and let me take you through building a production-ready serverless application from testing, deployment, security right through to observability. This workshop gives you hands-on experience building something with serverless technologies while giving you a broader view of the challenges you will face as the architecture matures and expands. By the end of the workshop, you should have a clear idea when serverless is a good fit for your system as well as common pitfalls you need to avoid.
Stumbled across this question on StackOverflow the other day, definitely one for the interview! The question goes:
How do you convert a string such as “01110100011001010111001101110100” to a byte array then used File.WriteAllBytes such that the exact binary string is the binary of the file. In this case it would be the the text “test”.
Here’s my take on the answer :-)
var binaryStr = "01110100011001010111001101110100"; var byteArray = Enumerable.Range(0, int.MaxValue/8) .Select(i => i*8) // get the starting index of which char segment .TakeWhile(i => i < binaryStr.Length) .Select(i => binaryStr.Substring(i, 8)) // get the binary string segments .Select(s => Convert.ToByte(s, 2)) // convert to byte .ToArray(); File.WriteAllBytes("C:\temp\test.txt", byteArray);
