Linux Candy: lolcat – rainbows and unicorns

Filed under

If you think being at the command-line is rather mundane and lacking a touch of sparkle, you couldn’t be further from the truth. We’ve looked at some really fun candy in our Linux Candy series. And there’s lots more to come.

Continuing in the theme of showing the lighter side of Linux, here’s a curious program. It’s called lolcat, an oddity that applies rainbow colors to text output in the terminal. It works in a similar way to the venerable cat command but jazzes things up with configurable rainbow colors.

There’s cross-platform support, with the software running on Linux, BSD, and OS X.

  • Cloning a MAC address to bypass a captive portal

    Captive portals are web pages offered when a new device is connected to a network. When the user first accesses the Internet, the portal captures all web page requests and redirects them to a single portal page.

    The page then asks the user to take some action, typically agreeing to a usage policy. Once the user agrees, they may authenticate to a RADIUS or other type of authentication system. In simple terms, the captive portal registers and authorizes a device based on the device’s MAC address and end user acceptance of terms. (The MAC address is a hardware-based value attached to any network interface, like a WiFi chip or card.)

    Sometimes a device doesn’t load the captive portal to authenticate and authorize the device to use the location’s WiFi access. Examples of this situation include mobile devices and gaming consoles (Switch, Playstation, etc.). They usually won’t launch a captive portal page when connecting to the Internet. You may see this situation when connecting to hotel or public WiFi access points.

    You can use NetworkManager on Fedora to resolve these issues, though. Fedora will let you temporarily clone the connecting device’s MAC address and authenticate to the captive portal on the device’s behalf. You’ll need the MAC address of the device you want to connect. Typically this is printed somewhere on the device and labeled. It’s a six-byte hexadecimal value, so it might look like 4A:1A:4C:B0:38:1F. You can also usually find it through the device’s built-in menus.

Proprietary Software: Grammarly, Microsoft and 'Big Tech'

Filed under
  • Why pay for Grammarly when you’re the one doing the work?

    Grammarly is a grammar and language analysis and correction service. It’s essentially providing those red and green squiggly lines that highlight your writing-mistakes in your favorite text editor. However, it’s offered as a software-as-a-service (SaaS) that can somehow afford non-stop ad-campaigns all over the web.

    This particular SaaS puts a premium price sticker on its service and then have you do manual labor for them to boot! I’ll start by taking a jab at how Grammarly has designed its product to prey on your insecurities. I’ll then move on to discuss its high asking-price considering how much value you’re providing it besides the dollar amount you’re asked to pay.

  • Goliath: Matt Stoller's book describe the rise of the tech giants

    Like the rest of the Clinton administration, the DOJ Antitrust Division in the 1990s talked populist, but governed with a deference to monopoly. Clinton’s first appointment to run the division was a Washington lawyer named Anne Bingaman. Antitrust was not particularly important to the administration, and it seemed to some that Bingaman got the job as a political favor to her husband, New Mexico senator Jeff Bingaman. “Hmph,” Attorney General Janet Reno said to The Wall Street Journal, “there’s the White House trying to push a Senator’s wife on me.”

    Nevertheless, when she took office, Bingaman was ready to entirely remake the dormant division. She “fired up” the staff, and opened up new investigations. “Anne Bingaman has a blunt message for corporate America: The antitrust cops are back on the beat,” said the Journal. One of Bingaman’s first goals was to open up the most important new area of the economy, the one where Reagan had allowed nascent robber barons to not only seize power over industry but over the future of technology. She would take on the big bad monopolist of the computer industry, Microsoft, which was frightening Silicon Valley, and increasingly, much of corporate America.

    In the 1960s, Silicon Valley was a middle-class area populated by farmers and engineers. Up until the early 1980s, the personal computing industry was largely a world of hobbyists, composed of tinkerers who played with what most businessmen thought were toys. Hobbyist culture was pervasive and utopianist, a combination of both the San Francisco counterculture scene and the Cold War–era New Deal high-tech can-do spirit. One of the early forums for the personal computer, for instance, the Homebrew Computer Club, inspired the design of the Apple I. Tinkerers passed around software to each other for free, updating and improving it collectively.

Two New Tools that Tame the Treachery of Files

Filed under

Parsing is hard, even when a file format is well specified. But when the specification is ambiguous, it leads to unintended and strange parser and interpreter behaviors that make file formats susceptible to security vulnerabilities. What if we could automatically generate a “safe” subset of any file format, along with an associated, verified parser? That’s our collective goal in Dr. Sergey Bratus’s DARPA SafeDocs program.

But wait—why is parsing hard in the first place? Design decisions like embedded scripting languages, complex context-sensitive grammars, and object models that allow arbitrary dependencies between objects may have looked like good ways to enrich a format, but they increase the attack surface of a parser, leading to forgotten or bypassed security checks, denial of service, privacy leakage, information hiding, and even hidden malicious payloads.

Two examples of this problem are polyglots and schizophrenic files. Polyglots are files that can be validly interpreted as two different formats. Have you ever read a PDF file and then been astonished to discover that it is also a valid ZIP file? Or edited an HTML file only to discover that it is also a Ruby script? Congratulations, you discovered a polyglot. This is not to be confused with schizophrenic files: That’s when two parsers interpret the same file in different ways, e.g., your PDF displays different content depending on whether you opened it in Adobe Acrobat or Foxit Reader, or your HTML page renders differently between Chrome and Internet Explorer.

GIMP 2.10.14 Released

Filed under

This is basically the first shot at the previously missing feature set, so expect more to land to GIMP at some point in the future. Making selection tools work outside the canvas sounds like a sensible next stop. Then maybe we can seriously talk about boundless canvas.

This new feature is closely related to out-of-canvas viewing and editing and was also contributed by Ell.

Now when you e.g. rotate a single-layer image, you can use this transform type to automatically expand the canvas to include all of rotated pixels when using the default Adjust clipping mode. The switch is right next to layer/path/selection toggle at the top of any transform tool’s settings.
