EARN IT: Privacy, Encryption, And Policing In The Information Age

May 6, 2020 by Jonathan Bennett 40 Comments

You may have heard about a new bill working its way through the US congress, the EARN IT act. That’s the “Eliminating Abusive and Rampant Neglect of Interactive Technologies Act of 2020”. (What does that mean? It means someone really wanted their initials to spell out “EARN IT”.)

EARN IT is a bipartisan bill that claims to be an effort to put a dent in child exploitation online. It’s also managed to catch the attention of the EFF, Schneier, and a variety of news outlets. The overwhelming opinion has been that EARN IT is a terrible idea, will make implementing end-to-end encryption impossible, and violates the First and Fourth Amendments. How does a bill intended to combat child pornography and sex trafficking end up on the EFF bad list? It’s complicated.

Sticking Up For The Stick Shift

May 5, 2020 by Kristina Panos 301 Comments

It seems that stick shift has become a sticking point, at least for American car buyers. Throughout 2019, less than 2% of all the cars sold in the US had a manual transmission. This sad picture includes everything from cute two-seater commuters to — surprisingly enough — multi-million dollar super cars built for ultimate performance.

But aside from enthusiasts like myself, it seems no one cares too much about this shift away from manual transmissions. According to this video report by CNBC (embedded below), the fact that demand is in free-fall suggests that Americans on the whole just don’t enjoy driving stick anymore. And it stands to reason that as more and more people live their lives without learning to drive them, there would be a decline in the number of teachers and proponents. It’s a supply and demand problem starring the chicken and the egg.

But giving up the stick is one more example of giving up control over the vehicle. It’s not something everyone cares about, but those that do care a lot. Let’s grind through the ebb and flow of the manual transmission — more lovingly called the stick shift.

Wolfram Physics Project Seeks Theory Of Everything; Is It Revelation Or Overstatement?

April 30, 2020 by Moritz v. Sivers 74 Comments

Stephen Wolfram, inventor of the Wolfram computational language and the Mathematica software, announced that he may have found a path to the holy grail of physics: A fundamental theory of everything. Even with the subjunctive, this is certainly a powerful statement that should be met with some skepticism.

What is considered a fundamental theory of physics? In our current understanding, there are four fundamental forces in nature: the electromagnetic force, the weak force, the strong force, and gravity. Currently, the description of these forces is divided into two parts: General Relativity (GR), describing the nature of gravity that dominates physics on astronomical scales. Quantum Field Theory (QFT) describes the other three forces and explains all of particle physics.

Using Valgrind To Track Down Known And Unknown Bugs In Your Code

April 29, 2020 by Maya Posch 17 Comments

We all know what bugs in code are. We don’t like them when they are in programs we use, and they’re even worse when they are in code which we have written. Clearly, the best code is bug-free, but how do we get there?

This isn’t a new question, of course, just one that has become ever more important as the total number of lines of code (LoC) that run modern day society keeps increasing and which is affecting even hobbyists more and more often now that everything has a microcontroller inside.

Although many of us know the smug satisfaction of watching a full row of green result markers light up across the board after running the unit tests for a project, the painful reality is that you don’t know whether the code really is functionally correct until it runs in an environment that is akin to the production environment. Yet how can one test an application in this situation?

This is where tools like those contained in the Valgrind suite come into play, allowing us to profile, analyze and otherwise nitpick every single opcode and memory read or write. Let’s take a look, shall we?

Greatest Keycaps And Where To Find Them

April 28, 2020 by Kristina Panos 25 Comments

Look at your keyboard. Do the keycaps excite you? That’s what we thought. You pound on that thing day in and day out. Shouldn’t it at least be attractive? Or even happiness-inducing? You don’t necessarily have to replace every single keycap to spark joy. When it comes to artisan keycaps, the point is to have something that stands out.

How about an Escape key that looks like a tall stack of flapjacks or a tiny, intricate cream puff? From a practical standpoint, how about a spiky Escape key that makes you think twice about rage quitting?

If you’re into games or anime, chances are good that there are more than enough artisan keycaps out there to keep you cash-poor for a while. The same goes for scrumptious foodstuffs with Cherry MX-compatible stems.

In this day and age, you can get just about any type of keycap you want, especially those encapsulating pop culture phenomena and fads. Yes there’s a fidget spinner keycap, and it’s adorable.

ReactOS: Dipping A Toe In A Millennium-era Open Source Dream

April 27, 2020 by Jenny List 57 Comments

Do you remember when trying a new OS meant burning a CD? Not merely downloading an ISO and mounting it on a USB drive, but taking a circle of polycarbonate and hoping you didn’t get a buffer underrun as the file you’d spent an entire day downloading was burned onto it. A couple of decades ago that was how we’d take a look at a new Linux distro, and at the time we considered it to be nothing short of incredible that such a thing was possible. One of the ISOs I remember downloading back then was an early version of ReactOS, a project with the lofty aim of creating an open-source equivalent of Windows NT. You might think that in the nearly two decades since then it would have become an irrelevance and its contributors moved on to other work, but no. ReactOS is very much still with us, and indeed has just seen a new release. Version 0.4.13 is the latest in a long line of incremental updates, and remembering those early ReactOS ISOs when I saw their announcement, I thought I’d give it a spin. The result was both a peek at the current state of the project, and a chance to think about the place of a Windows clone in 2020.

Limiting Factor Submersible Is In A League Of Its Own

April 22, 2020 by Kristina Panos 26 Comments

Space may be the final frontier, but there are still Earthly frontiers that a select few have visited — the deepest depths of the high seas. Victor Vescovo, a Texas businessman and former Naval officer, is one of those few. Last spring, Vescovo realized his dream of becoming the first person to scrape the bottoms of all five oceans.

Vescovo descended alone in Limiting Factor, a $37 million two-seater submersible he commissioned from Triton, a private manufacturer who made this feat of engineering come to life. Vescovo and the crew discovered over 40 new species of aquatic lifeforms throughout the course of their Five Deeps expedition. But the attention-getting takeaway came when Vescovo visited the absolute lowest point on Earth. In the Challenger Deep portion of the Marianas Trench, seven miles below sea level, he saw a plastic bag drift by in the abyss.

One normal-sounding quirk sets this sub apart from others: it’s made to be reusable. You read that right, most super-deep divers never manage to dive over and over again.
