  • Glitch Your Way To Reverse-Engineering Glory With The PicoEMP | Hackaday

    Most of our projects are, to some extent, an exercise in glitch-reduction. Whether they’re self-inflicted software or hardware mistakes, or even if the glitches in question come from sources beyond our control, the whole point of the thing is to get it running smoothly and predictably.

    That’s not always the case, though. Sometimes inducing a glitch on purpose can be a useful tool, especially when reverse engineering something. That’s where this low-cost electromagnetic fault injection tool could come in handy. EMFI is a way to disrupt the normal flow of a program running on an embedded system; properly applied and with a fair amount of luck, it can be used to put the system into an exploitable state. The PicoEMP, as [Colin O’Flynn] dubs his EMFI tool, is a somewhat tamer version of his previous ChipSHOUTER tool. PicoEMP focuses on user safety, an important consideration given that its business end can put about 250 volts across its output. Safety features include isolation for the Raspberry Pi Pico that generates the PWM signals for the HV section, a safety enclosure over the HV components, and a switch to discharge the capacitors and prevent unpleasant surprises.

  • Solve Wordle using the Linux command line | Opensource.com

    I've recently become a little obsessed with an online word puzzle game in which you have six attempts to guess a random five-letter word. The word changes every day, and you can only play once per day. After each guess, each of the letters in your guess is highlighted: gray means that letter does not appear in the mystery word, yellow means that letter appears in the word but not at that position, and green means the letter appears in the word at that correct position.

  • GravityMark 1.44 Released With Ray-Tracing Support - Phoronix

    Those wanting to enjoy some impressive Vulkan ray-traced visuals on Linux (and macOS or Windows) now have GravityMark to add to the list of Linux-native ray-traced software for testing.

    GravityMark is the new graphics benchmark from Tellusim, the company led by Alexander Zapryagaev who was one of the original Unigine co-founders. GravityMark has been quite impressive for a free and cross-platform, cross-API benchmark while with this weekend's v1.44 release is even more impressive now that there is DirectX 12 / Vulkan / Metal ray-tracing support.

  • How to Connect Wi-Fi using Nmcli in Linux

    Why use the Network-command-line Manager’s interface? Sometimes Ubuntu Network Manager behaves strangely, and you may be unable to connect to any Wi-Fi Hotspot using the GUI (Graphical user interface). The Network Manager may fail to start, and even after manually restarting the service through the terminal, you may still have difficulties connecting to any Wi-Fi Hotspot, even a previously recognized and stored home network. I encountered same problem on dual boot configurations and standalone Linux installs, and it was quite inconvenient, particularly during the WFH (Work from home) phase that we’re all going through.

  • How to Add Comments to UFW Rules

    In an earlier article we discussed how to add comments to iptables rules for clarity and documentation. In our opinion it is a good practice to comment anything someone else may have to work on in the future. Using comments in scripting is a common practice for good reason. We decided to write a quick tip on how to add a comment to UFW (Uncomplicated Firewall) rules. I am not a huge fan of UFW or Firewalld. In my opinion they make managing netfilter harder, not easier. That is because I started using iptables over 20 years ago. I am very comfortable with it and tend to know the necessary syntax off the top of my head. That being said, adding a comment to UFW rules is much more intuitive than any other iptables front end.

GNOME and KDE: This Week in GNOME, Qt6 and KF6

  • #44 Five Across · This Week in GNOME

    Update on what happened across the GNOME project in the week from May 13 to May 20.

  • Okteta making a small step to Qt6 | Attracted by virtual constructs

    Old, but stable, even more in when it comes to the feature set, and still getting its polishing now and then: your simple editor for the raw data of files, named Okteta. What started in 2003 as a hex editing widget library for KDE3 (and Qt3), of course named KHexEdit (to be confused with the unrelated hex editor program that was part of KDE at that time), it turned into a first dedicated application by the title Okteta during the years 2006 to 2008 for KDE4 (and Qt4). From there on a small set of features was added once in a while, most impressively Alexander Richardson’s Structures tool in 2010,. Until then in 2013 the port to Qt5/KF5 was done (also to a good degree by Alexander). After that things had settled, the program working properly when needed, otherwise just left in the corner of the storage. Now, nearly 2 decades after the first lines were written, the next port is to be done, to Qt6 and KF6. And this time the actual port is just amazingly boring: changing a few “Qt5” to “Qt6” in the buildsystem (and later some “KF5” to “KF6” once KF6 is ready), adding Qt6::Core5Compat as helper library for 1-2 classes that had not yet been substituted, adding a “const” to the argument of an overridden virtual method, adapting some “QStringList” forward declarations… and done.

The 5 best Application Launchers for Ubuntu

Every operating system comes with an application launcher where you have to mouse over the entire menu to launch an application. But, unlike other operating systems, Linux allows us to install other launchers as an alternative. In this post, We came up with the five best application launchers for Ubuntu and their installation process. Ubuntu has a default application launcher, i.e., GNOME Shell application overview. If you are a beginner or a tech professional, browsing the entire menu to launch an application is quite bothersome. Linux community offers a wide variety of application launchers.
