CloudWatch metrics for SQS queues are collected and pushed to CloudWatch at one-minute intervals automatically. These metrics are provided at no charge in CloudWatch for both standard and FIFO queues. In this article, we will create an alarm for the "NumberOfMessagesSent" metric.

If you use Git regularly, you might be aware that it has several reputations. It's probably the most popular version-control solution and is used by some of the biggest software projects around to keep track of changes to files. It provides a robust interface to review and incorporate experimental changes into existing documents. read more

Many people consider hard drives secure because they physically own them. It's difficult to read the data on a hard drive that you don't have, and many people think that protecting their computer with a passphrase makes the data on the drive unreadable. This isn't always the case, partly because, in some cases, a passphrase serves only to unlock a user session. In other words, you can power on a computer, but because you don't have its passphrase, you can't get to the desktop, and so you have no way to open files to look at them. read more

On Linux, it's common to create shell scripts to automate repetitive tasks. Similarly, on FreeDOS, the open source implementation of old DOS operating systems, you can create a batch file containing several FreeDOS commands. Then you can run your batch file to execute each command in order.

Git is designed in part to enable experimentation. Once you know that your work is safely being tracked and safe states exist for you to fall back upon if something goes horribly wrong, you're not afraid to try new ideas. Part of the price of innovation, though, is that you're likely to make a mess along the way. Files get renamed, moved, removed, changed, and cut into pieces. New files are introduced. Temporary files that you don't intend to track take up residence in your working directory. read more

They say software is eating the world, but it's equally clear that open source is taking over software. Simply put, open source is a superior approach for building and distributing software because it provides important guarantees around how software can be discovered, tried, operated, collaborated on, and packaged. For those reasons, it is not surprising that it has taken over most of the modern data stack: Infrastructure, databases, orchestration, data processing, AI/ML, and beyond. read more

Not to worry, zombies with a gambling addiction probably won't eat your enterprise brains Column It seemed like a classic April The First spoof.
