Zombies are bad at understanding boundaries. They trample over fences, tear down walls, and generally get into places they don't belong. In the previous articles in this series, I explained why tackling coding problems all at once, as if they were hordes of zombies, is a mistake.

The latest heap buffer overflow vulnerability discovered in sudo (CVE-2021-3156) can trigger privilege escalation and allow any unprivileged user (those not in the sudoers list, or even nobody) to bypass password authentication and gain the root access. This vulnerability can easily be exploited as the second-stage attack once a low-level service account gets breached. This tutorial describes how to check if your sudo is vulnerable and how to update it on your Linux system.

I work with media, and when you work with any kind of media, you learn pretty quickly that standardization is a valuable tool. Just as you wouldn't try to add a fraction to a decimal without converting one or the other, I've learned that it's not ideal to combine media of differing formats. Most hobbyist-level applications make the conversion process invisible to the user as a convenience. Flexible software aimed at users needing control over the fine details of their assets, however, often leave it up to you to convert your media to your desired format in advance. read more

In the previous articles in this series, I explained why tackling coding problems all at once, as if they were hordes of zombies, is a mistake. I'm using a helpful acronym explaining why it's better to approach problems incrementally.

Pre-compilation tech means faster startup and lower memory overhead, to make Java cool for microservices. Oracle has sweetened its Java SE subscriptions by tossing in a free entitlement to use GraalVM, a new universal virtual machine that Big Red says runs just about anything faster, anywhere.…

Applications very often save data. Whether your users create simple text documents, complex graphic layouts, game progress, or an intricate list of customers and order numbers, software usually implies that data is being generated. There are many ways to store data for repeated use. You can dump text to configuration formats such as INI, YAML, XML, or JSON, you can write out raw binary data, or you can store data in a structured database.

Software libraries are a longstanding, easy, and sensible way to reuse code. This article explains how to build libraries from scratch and make them available to clients. Although the two sample libraries target Linux, the steps for creating, publishing, and using these libraries apply to other Unix-like systems.

Community? 'The software isn’t changing at all. This is a label on the name, nothing else'.

Automated tests are part of many programming projects, ensuring the software is flawless. The bigger the project, the larger the test suite can be.This can result in automated tests taking a lot of time to run. In this article you will learn how to run automated tests faster with parallel Continuous Integration machines (CI) and what problems can be encountered. The article covers common parallel testing problems, based on Ruby & JavaScript tests.
