An 8-bit microprocessor is a type of microprocessor that processes data and executes instructions using 8-bit binary numbers. In simple terms, it means that the processor can handle data in chunks that are 8 bits wide. This tutorial walks through building a fully programmable 8-bit computer from simple logic gates on breadboards. Included are parts lists, sources, and schematics to make it easier to follow along or even build your own!

ESP8266 is just a chip name that many companies has designed their own board for it. The most interesting thing is they have Wifi so you can do a lot of IoT with it. Many of them cost just $5 for a board. Also, checkout the ESPHome project for similar thing as well.

An amazing crack that doesn’t patch the original binaries. How does it works? by using

Given a dom node object, what is the different between div.getAttribute(‘foo’) and div.foo? sometime they are same, some time they are different. why so?

In this blog, we’ll discuss an idea called “Parallel Snapshotting”. This idea could be integrated into Postgres upstream in the future to make pg_dump and pg_restore parallelizable at a single table level.

Before we discuss what VACUUM does and its implication. How data is actually stored on disk. What happens when a tuple is inserted, updated, or deleted? Understanding this will help us understand what VACUUM does, why it’s needed, and its implications.

In this article, you will understand ARNs and their significance within the Amazon Web Services (AWS) ecosystem. You’ll get to dissect the structure of an ARN and how you can retrieve them. By the end of this article, identifying and deciphering ARNs will be a breeze for you.

Even it target at Go, this articule is useful for anyone want to sign binary so it can run on MacOS Catalina and later without gotting the unidentified warning.
