Mozilla: Extensions in Firefox 78, uBlock Origin and What UX Writers Can Learn From Poetry

  • Extensions in Firefox 78

    In Firefox 78, we’ve done a lot of the changes under the hood. This includes preparation for changes coming up in Firefox 79, improvements to our tests, and improvements to make our code more resilient.

  • UBlock Origin - a powerful Internet purification tool

    Every now and then, I receive an email from a reader asking me why I'm not using uBlock Origin. Or rather, why Adblock Plus and not uBlock Origin? Alas, the question is based on a wrong assumption. I do use it, I use them both (not at the same time), and it's on several of my recommended software lists. But I've never given it a proper review. Time to rectify that.

    The modern Internet is a cesspit. A filthy place with tiny, isolated pockets of goodness. Adblocking isn't there to kill revenue streams for indie websites, it's there to stop nonsense from becoming the dominant force of any and every Web experience. Helping turn the tide are a few brave champions. I've already reviewed uMatrix, and you know my all-time-favorite Noscript. Now, let's have a look at uBlock Origin.


    UBlock Origin will only block ads and trackers by default. But you can do more. You can disable Javascript, media files, fonts, as well as popups. Then, you can also pick elements from a loaded page and manually remove (zap) them, if you like. This can be helpful if you encounter annoyances that aren't picked up by your filters, or perhaps you want to get rid of something you consider harmful or silly, but it doesn't fall under any existing category.


    All in all, uBlock Origin is a fantastic tool. It's powerful, versatile, robust - and it doesn't cause any browser slowdown. Some extensions can be heavy, but in this case, the impact is minimal. Very refreshing and useful. Then, the simple/advanced mode offers the best of both worlds - ordinary users and nerds alike will find the level of control they need and feel comfortable with. Being able to turn Javascript off is another valuable asset.

    I don't have anything bad to say really - some extra rigor is needed now and then, just to make sure you don't end up with legitimate content being blocked. But from what I've seen - we're talking long testing on multiple systems, over a couple of years, the false positives, when they do occur, are far and few in between and usually related to fonts. Ublock Origin does a great job, and its biggest challenge is making a difficult, complex task even easier to present. Should one deliberately seek drawbacks, the abundance of options stored in a small UI could be its Achilles' Heel. It's not easy creating visual minimalism without sacrificing actual functionality, but at the moment, uBlock Origin might be somewhat daunting to those less tech-savvy. Highly recommended, and I hope this finally answers the myriad emails on this topic. May your Internet be pure.

  • The Poetics of Product Copy: What UX Writers Can Learn From Poetry

    Word nerds make their way into user experience (UX) writing from a variety of professional backgrounds. Some of the more common inroads are journalism and copywriting. Another, perhaps less expected path is poetry.

    I’m a UX content strategist, but I spent many of my academic years studying and writing poetry. As it turns out, those years weren’t just enjoyable — they were useful preparation for designing product copy.

    Poetry and product copy wrestle with similar constraints and considerations. They are each often limited to a small amount of space and thus require an especially thoughtful handling of language that results in a particular kind of grace.

  • How To Install HAProxy on CentOS 8 - idroot

    In this tutorial, we will show you how to install HAProxy on your CentOS 8. For those of you who didn’t know, HAProxy is a free HTTP/TCP high availability load balancer and proxy server. It spreads requests among multiple servers to mitigate issues resulting from a single server failure. HA Proxy is used by a number of high-profile websites including GitHub, Bitbucket, Stack Overflow, Reddit, Tumblr, Twitter, and Tuenti, and is used in the OpsWorks product from Amazon Web Services. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step by step installation HAProxy on a CentOS 8.

  • YAML for beginners | Enable Sysadmin

    YAML Ain't a Markup Language (YAML), and as configuration formats go, it's easy on the eyes. It has an intuitive visual structure, and its logic is pretty simple: indented bullet points inherit properties of parent bullet points. But this apparent simplicity can be deceptive. It's easy (and misleading) to think of YAML as just a list of related values, no more complex than a shopping list. There is a heading and some items beneath it. The items below the heading relate directly to it, right? Well, you can test this theory by writing a little bit of valid YAML.

  • colorls – turbocharged alternative to ls

    The part of the operating system responsible for managing files and directories is called the file system. It organizes our data into files, which hold information, and directories (also called ‘folders’), which hold files or other directories. Several commands are frequently used to create, inspect, rename, and delete files and directories. One of these commands is ls, which prints the names of the files and directories in the current directory. A directory is really just a file. It’s a special file with special rules. The ls utility appeared in the first version of AT&T UNIX. Are you looking to liven up your shell? Want a bit more beauty on your terminal? colorls might be the ticket. colorls is a command-line utility that aims to improve on ls. color is written in Ruby.

Linux Patches Aim To Provide Fork'ing Brute Force Attack Mitigation

Building off a set of "request for comments" patches from September, a set of patches were sent out on Sunday for providing brute force attack mitigation around the fork system call. With attacks aiming to break Address Space Layout Randomization (ASLR) and similar attacks often relying on the fork system call in order to keep replicating the memory contents of the parent process, these patches aim to detect the behavior where fork is being exploited for these nefarious purposes. This work is inspired in part by some patches carried by GrSecurity where a delay around the fork system call will be imposed if a child died from a fatal error. These patches propose collecting statistical data shared across all the processes with the same memory contents and analyzing the timing of any children processes crashing. When the code determines such an exploit may be underway leveraging fork, all of the processes using the same memory contents are killed to stop whatever malicious activity may be happening.

Manage content using Pulp Debian

Pulp is an open source repository management tool that helps you fetch, mirror, upload, and publish content within your organization. It can be used to manage various types of content such as software packages (from RPM packages to Ruby gems), as well as Ansible collections, container images, and even arbitrary files.
