  Some tricks on PHP session

1. Session timeout problem There is a nuance we found with session timing out although the user is still active in the session.  The problem has to do with never modifying the session variable. The GC will clear the session data files based on their last modification time.  Thus if you never modify the session, you simply read from it, then the GC will eventually clean up. To prevent this you need to ensure that your session is modified within the GC delete time.  You can accomp...

What should a ‘cache’ be? It means a lot of things, but to my mind the default programming type should be: “keep around expensive-to-generate bits of read-only data in case we need them again, or until the computer really needs that RAM for something else” I was writing a custom video editing program in Python (interesting choice of language for that problem) and I wanted to cache decoded frames; but I just wasn’t happy with the memory management of explici...

Are you used to use cPanel or Plesk on VPS for your PHP website management? If for some reason you don't want to use them? What can you do? How do you maintain your website? How do you access Emails, use FTP to upload files or use phpMyAdmin to manage your databases? You may need to configure all these services yourself on a VPS without cPanel or Plesk or other similar apps.But to configure all these services on a Linux server is not an easy job.

  Emacs adventures

I have been using Emacs for over a year now. I actually didn’t learn a lot when I started using it (just the basics to get going and then some relatively common keyboard shortcuts), but lately I have been reading and learning much more about it. I’m so grateful by everything I’ve learned from different people on the net that I wanted to share a couple of things I’ve learned, and a simple major mode for editing AsciiDoc documents. As a long-time VIM user, I f...

  The Most Popular Car Color

Is there a most popular color among humans as a group? While the answer to this question depends on the definition of "most popular," there is an objective way to consider it: by looking at what color of cars sells the best. The color that has the highest sales in the car market indicates the public's strong preference for that color. Last week, a U.S. automotive website released the ranking of colors for all new cars sold in the U.S. in 2023. The result showed that shades of gray are the most ...

  How multitasking really works on Android and iOS

As the horsepower packed into mobile devices gets ever greater, more full-featured forms of multitasking are possible. The market leaders have very different ways of going about things, and there are numerous misconceptions about what is going on behind the scenes. This isn’t all the fault of the user, though. In the interest of ease of use, sometimes the multitasking metaphor is overly simplified on both Android and iOS. iOS: It’s more complicated than it looksEver since iOS...

  7 Resources Every JavaScript Developer Should Know

A web developer today is expected to be an expert in every aspect of their craft and JavaScript is no exception.  Years ago JavaScript seemed to be more of an annoyance, producing those trailers at the bottom of the browser.  This has changed and JavaScript is a first-class citizen as a functional programming language and what seems like an unlimited number of resources covering the language. I have been doing more and more JavaScript lately, both on the front-end and some node.js...
