Note to self: Don't write your own encryption.

There are already capable, tested and even tried an true encryption algorithms. Implemented across platforms and languages and built into libraries and services. And did I mention "Tested"? With mathematical validations of how hard they should be to crack?

If you actually need to encrypt things, then use existing algorithms and software to actually encrypt things. You'll have enough to worry about with key management, library verifications and making sure the rest of the team gets up to speed that, no, it's not just Easier | Faster | Better to do it yourself.

Unless of course your sole job is creating, writing, testing, proving and implementing encryption algorithms, because you have all the maths...

Files as UI

Files as UI vs API - compares attributes of iCloud vs Dropbox. It starts on an interesting note - the model of a file system in the UI is dying, and should be let go. Beyond that it looks at mappings of each system to a file system from an API point of view and compares the successes of each. I find the initial thread the most interesting. Drop the mental model of a file system - which maps virtual concepts of files and directories to a physical model of papers, folders and file cabinets - and replace it with...what? This is a paradigm shift for me. I have to admit, I loath, hate, nay, despise looking for things. If I can't find something easily, it's only about a minute before I start growling and muttering things my mother would disapprove of. On this basis, I like the idea that I can save myself from thinking about where to put things or, where I have already put them. But how do we do this? It's non-trivial, since humans think of "things" and once they ...

It's all broken...

So, Scott Hanselman struck a chord again: Everything's broken and nobody's upset . The worst part is I can see that I'm part of the problem on both sides . I've excused many problems with software - shrugging as I restart the software or reboot. I save my anger for those occasions where I fell I've lost serious work and substantial time. Other than that I accept problems, glitches, crashes as "the cost of doing business". I believe it's actually because I've amused myself and earned a living creating software, that I am able to accept what's often pitiable quality. I've spent time working on systems that are not much more than breadboards with wires cascading from it, where getting something, anything to work was a huge accomplishment. But that was then and this is now. No way would I put up with a car that suffers from numerous small problems as today's software can. And putting these two thoughts together, it's now frightening ...

Let's Not Mess Around with Security on our Personal Systems Either!

Essential Security Practices for Your Personal Systems Ensuring a minimal level of cybersecurity, privacy, and availability on your personal systems means you need to manage the following essential practices. This is a brief overview of recommendations from sources like CISA, NSA, etc., focused on personal laptop, phone, and other systems' security. Anti-virus I've found you'll get the best anti-virus protection and usability from a paid product - I've always had good luck with Norton labeled products. If you are looking for current vendor offerings see: https://www.pcmag.com/picks/the-best-antivirus-protection Regardless of whether you choose to use a commercial product or open-source anti-virus tool, it is absolutely something you need to use. This is the minimally needed level of system security. Once installed, ideally, it should be invisible until there's a security problem it can't prevent or solve. Backups You need to have at least a minimal level of ...
