A food delivery drone operated by Alphabet subsidiary Wing crashed into powerlines in Brisbane, Australia on Thursday, catching fire and falling to the ground, which probably overcooked the food.

On the flip side, it won’t work at all for non-graphical programs....

What Is a Decentralized VPN, and Why Would You Use One? There are a few reasons why you’d use a decentralized VPN over a regular one. Some are more practical, while others are more high-minded.

There is a nice and simple command line program called uname that will tell us exactly that. Open a terminal window (Applications > Accessories > Terminal).

You’ll see one using just two columns of data sequentially and the other using three columns with the data stacked....

How Much Power Can You Really Save? To demonstrate how much of a difference changing your TV settings can make to its power draw, we’re using a 555Wh lithium battery pure sine inverter that shows the current power draw on its display. The power pack also estimates how much time is left before running out of juice. If the load is 100W, you’ll consume 500Wh of power in five hours. On the other hand, if the load is 50W, the time doubles....

CodeCommit is AWS’s managed source control solution. It’s a crucial component in AWS’s CodeSuite CI/CD pipeline, which makes it easy to run frequent code builds and deploy application updates programmatically to your EC2 servers or Lambda functions. What Is CodeCommit? Really, CodeCommit by itself isn’t fantastic. It works well as a basic source control provider, and you can certainly use it as your primary repository, but it does fall a bit short of the competition—GitHub, GitLab, BitBucket, and others—when it comes to day-to-day usability....

Setting up database backups is the most important thing to handle as a database administrator.

The most headache-free backup strategy is to use a fully managed Database-as-a-Service, and configure automatic backups from their control panel.

PHPStan is a static analysis system for PHP projects. It finds bugs in your codebase by inspecting the source files. You don’t need to run your code or manually write tests to discover issues! The term “static analysis” is defined as debugging code without actually executing it. It’s most often used with interpreted languages, such as PHP, as the issues it finds tend to surface at the compilation stage in compiled languages....

Test Browser and Mobile Compatibility You probably only use one browser, but the rest of the Internet uses a wide variety of browsers. You should test your site in Chrome, Firefox, Edge, and Safari. Check to make sure your site looks the same, as certain browsers can handle CSS differently. For example, intrinsic & extrinsic sizing ( width: fit-content ) has a few bugs in Firefox, so you should make sure you have fallbacks in case the browser doesn’t know how to handle it....

The Value of Backups All hardware has a finite life. Mechanical hard disk drives (HDDs) and solid-state drives (SSDs) don’t last forever. Accidents happen, too. Laptops can be lost, stolen, or dropped down the stairs. It used to be said that the value of an effective backup system only becomes clear once you’ve lost data. When failures or losses occur, you need to have a fast and easy way to get your files and information back....
