tl;dr in tech by Joe Karlsson - Issue #59

tl;dr: Top 5 in order are JS, Python, Java, PHP and C#, with the following trends to note:

1) Despite its meteoric rise, TypeScript has stalled in the rankings holding its ground at eighth.

2) Go has also stalled, never placing higher than 14th and having dropped into 16 for the last three runs.

tl;dr: “Very few hashing algorithms are usable in more than a couple of situations. Even worse, using the wrong algorithm will lead in the best case scenario to performance problems, but in the worst case scenario to security issues and even financial loss. Thus, knowing which algorithm to pick for which application is crucial.”

tl;dr: “In the rest of this post you’ll see where I started, what I went through, what I learned along the way, and how it slowly evolved into the finally chosen image. I will only show the mostly happy path here. I will also only show images that were fairly ok (discarding the other 70+% that were terrible).”

tl;dr: “Progressing, in general, is a two-stage problem: you need to discover where it is that you’d like to go, and then you need to take positive action to work towards it. In my experience, many people over index on the prescriptive “how” before spending enough time on the “what”. The search space of possibilities for your career trajectory is effectively unbounded, and can rarely be predicted over long enough periods of time. This is a feature, not a bug, and should be embraced.”

tl;dr: “My best explanation for this is that most people learn a tool through searching, not browsing. When you search, you’re trying to find information that solves your specific need. When you browse, you’re systematically going through information for learning or later lookup.”

tl;dr: “You need to develop skills that give you the leverage to show bigger value to the company. These could be interpersonal skills that make you more trusted and valued, execution skills that let you drive complex projects to success, strategic skills that give you bigger ideas and the ability to sell them, or, occasionally, expert skills that make you very hard to replace.”

tl;dr: “Earlier this year I created Password Purgatory with the singular goal of putting spammers through the hellscape that is attempting to satisfy really nasty password complexity criteria.”
