This is a video of Foggy Mountain Spaceship performing a challenging 5/4 time cover of John Carpenter’s Halloween theme on a trio of banjos. It’s a tasty jam. Really made me want to rewatch Halloween. I’m not sure I’ll be able to find the time though, my girlfriend already has all our spooky movies carefully mapped out through the 31st. One night I tried suggesting a substitution. HUGE mistake. Way scarier than any movie.

The German Koblenz Regional Court has banned the internet service provider 1&1 from marketing its fiber-to-the-curb service as fiber-optic DSL. The court found that the company misled customers because its network uses copper cables for the final stage of connections, sometimes extending up to a mile from the distribution box to subscribers’ homes.

Customers who visited the ISP’s website and checked connection availability received a notification stating that a “1&1 fiber optic DSL connection” was available, even though fiber optic cables terminate at street-level distribution boxes or building service rooms. The company pairs the copper lines with vectoring technology to boost DSL speeds to 100 megabits per second. The Federation of German Consumer Organizations filed the lawsuit. Ramona Pop, the organization’s chairperson, said that anyone who promises fiber optics but delivers only DSL is deceiving customers.

JetBrains released its annual State of the Developer Ecosystem survey in late October, drawing more than twenty-four thousand responses from programmers worldwide. The survey declared that PHP and Ruby are in “long term decline” based on usage trends tracked over five years. Shortly after publication, JetBrains posted a separate statement asserting that “PHP remains a stable, professional, and evolving ecosystem.” The company offered no explanation for the apparent contradiction, The Register reports.

The survey’s methodology involves weighting responses to account for bias toward JetBrains users and regional distribution factors. The company acknowledges some bias likely remains since its own customers are more inclined to respond. The survey also found that 85% of developers now use AI coding tools.

TikTok changed its policies earlier this year on sharing user data with governments as the company negotiated with the Trump Administration to continue operating in the United States. The company added language allowing data sharing with “regulatory authorities, where relevant” beyond law enforcement. Until April 25, 2025, TikTok’s website stated the company would notify users before disclosing their data to law enforcement. The policy now says TikTok will inform users only where required by law and changed the timing from before disclosure to if disclosure occurs. The company also softened its language from stating it “rejects data requests from law enforcement authorities” to saying it “may reject” such requests. TikTok declined to answer repeated questions from Forbes about whether it has shared or is sharing private user information with the Department of Homeland Security or Immigration and Customs Enforcement. The timing difference prevents users from challenging subpoenas before their data is handed over.

This is a video of cats experiencing thick water for the first time. What’s thick water? Water that’s had a thickening agent like xanthan gum or modified cornstarch added to make it more viscous for people with dysphagia (a medical condition that makes it difficult to swallow non-viscous liquids without choking). I have not experienced thick water myself, but it looks like a good time. Now *ripping shirt off* fill the baby pool and let’s wrestle!

Exercise is a healthy and, one might argue, necessary part of our lives. The guidelines from public health organizations tell you to aim for at least 150 minutes of “moderate” exercise each week, and that each minute of “vigorous” exercise counts double. That raises the question: What the hell is “moderate” exercise? How do you know when you’re doing it? 

Scientists measure METs, but you don’t have to 

If you have any kind of smartwatch or fitness tracker, it may try to tell you that “moderate” exercise occurs at a certain heart rate. This isn’t actually the case. The scientists who came up with the exercise guidelines didn’t use heart rate as their guide. Instead, they used charts that measured how many “METs,” or metabolic equivalents, each type of exercise requires.

I’ll explain more about METs below, but the important thing to know is that the type and intensity of exercise is what tells you whether it’s moderate, not your heart rate while you’re doing it. You can look up exercises on a chart like this one, but here’s the basic idea: 

• Walking is moderate, jogging or running is vigorous.

• Bicycling is moderate if it’s under about 12 miles per hour on the flat.

• Indoor cycling is moderate if it’s up to about 100 watts of power.

All that said, you don’t have to overthink it. The guidelines that mention “moderate” and “vigorous” activities aren’t asking you to monitor your heart rate or any other numeric metric. They want you thinking in terms of generalities: walking versus running, leisurely bike commuting versus sweating your heart out in a spin studio.

And honestly, if it’s easier to watch your heart rate than to worry about the above, that’s fine. For most of us, 150 minutes of Zone 2 is going to be at least 150 minutes of moderate exercise. So follow that guideline, and you’ll be an overachiever.

It’s not really about heart rate

So why does your watch want to steer you toward a certain heart rate during exercise? Mostly because that’s easy to measure. Moderate exercise sorta-kinda matches up to “zone 2” cardio, which I’ve previously explained. (Zone 2 is is the second-lowest intensity in a five-zone system, and the easiest way to know which zone you’re in is to glance at your fitness watch.)

While you can use heart rate zones as a rule of thumb to find moderate exercise, this idea falls short in two ways: (1) different gadgets and systems use different cutoffs to decide which numbers count as “zone 2”, and (2) for most of us, zone 2 includes most moderate activities but also some vigorous activities. If you’re relatively fit, you can jog at a 12 minute-per-mile pace while keeping your heart rate in zone 2. That’s a “vigorous” activity in terms of METs, though. 

The other reason heart rate isn’t accurate for this task is that your heart rate changes for all kinds of reasons. The hotter it is when you’re working out, the higher your heart rate tends to be. Same goes for when you’re nervous or stressed. And as you get fitter, you’ll be able to do the same activities at a lower heart rate. Those activities might feel easier than they used to, but they’re not any less work. 

What is a MET, anyway?

One MET is the energy expended when you’re at rest—the amount of oxygen, calories, etc that it takes to keep you alive and breathing. (We use oxygen in the process of burning calories, so officially a MET is 3.2 milliliters of oxygen per kilogram of body weight per minute.) 

Researchers can then put a mask on a person and measure how much oxygen they use while running, walking, playing guitar, etc. If an activity takes twice as much oxygen as sitting still, they say it takes two METs. Here are a few examples (taken from this scientific paper): 

• 2 MET: washing dishes, or playing croquet

• 3 MET: walking at 3 miles per hour (a pretty typical walking pace)

• 4 MET: table tennis, ice skating

• 5 MET: modern dance, fast-paced ballroom dance

• 6 MET: volleyball, singles tennis

• 7 MET: jogging, jumping rope

The numbers go up from there. Speed skating clocks in at 15 MET. To be clear, you will not be measuring METs directly when you exercise. The MET studies are done in labs so that we can use the information to get a sense of what MET values each common type of exercise tends to have.

Moderate exercise is 3 to 6 MET, and vigorous is 6 or more

The physical activity guidelines define “moderate” exercise as at least 3 MET, but less than 6. Vigorous is 6 MET or more. 

Because METs are specific to the activity, not to how fit you are, it makes the most sense to look at METs in terms of the pace you run or the settings you use on your treadmill or other cardio machine. Here are paces and activities that have been clocked as between 3 and 6 METs: 

• Walking at 3-4 mph (a 15-minute to 20-minute mile)

• Cycling, between 50 to 100 watts

• Shooting baskets

• Playing baseball

• Taking a low-impact aerobics class

And these are vigorous (6 or more MET): 

• Race walking (5+ mph) 

• Walking uphill

• Walking with a 12-pound pack

• Jogging (a 12-minute mile is 8.0 MET; the faster you go, the higher the MET)

• Bicycling at 12 miles per hour or faster

• Swimming laps

• Playing a game of basketball, soccer, or hockey

So when you’re trying to get your 150 minutes (or more) of moderate exercise each week, you can count all your walking, your easy bike riding, and your low-impact aerobics class. Give yourself credit for vigorous exercise for all the time you spend jogging (at any heart rate), lap swimming, or rucking. You may find you’ve been doing more exercise than you think.

Apple’s effort to reinvent the iPad by adding a giant foldable screen has hit development hurdles, potentially delaying the planned launch. Bloomberg: The company has been working on the device — projected to cost around $3,000 — for several years and had most recently aimed for a 2028 release. But engineering challenges tied to weight, features and display technology have pushed its potential debut to 2029 or later, according to people familiar with the matter.

Apple is working with Samsung Display Co. to develop the roughly 18-inch panel for the device, said the people, who asked not to be identified because the work isn’t public. The screen minimizes the crease seen on foldable displays, matching an approach that Apple is also using with its upcoming foldable iPhone. The iPad project is part of a broader push to bring more innovative devices to market. Apple just introduced its first new iPhone design in years — the ultrathin $999 Air model — and is working on everything from smart glasses to a tabletop robot device.

“Plasma is a popular desktop (and mobile) environment for GNU/Linux and other UNIX-like operating systems,” writes longtime Slashdot reader jrepin. “Among other things, it also powers the desktop mode of the Steam Deck gaming handheld. The KDE community today announced the latest release: Plasma 6.5.” From the announcement: This fresh new release is all about fine-tuning, fresh features, and a making everything smooth and sleek for everyone. The new version brings automatic light-to-dark theme switching based on the time of day. You can configure which global themes it switches between. You can also configure whether you want the wallpaper to switch between its light and dark versions based on the color scheme, the time of day, or be always light or dark.

Next up is a “Pinned clipboard items” feature, which lets you save text you use regularly into the clipboard. Breeze-themed windows will now have the same level of roundness in all four corners, even the bottom one. Flatpak Permissions page has been transformed into a general Application Permissions page, where you can configure applications’ ability to do things like take screenshots and accept remote control requests. The utility that reads the level of ink or toner from your printer now informs you when it’s running low or empty.

For the gamers out there, you can now see more relevant info about game controllers on System Settings’ Game Controller page. Artists among you can now configure any rotary dials and touch rings on your drawing tablet. Users sensitive to color can now make use of a grayscale color filter, which desaturates or removes color systemwide.

Plasma 6.5 implements support for an experimental version of the Wayland picture-in-picture protocol that promises to allow apps like Firefox to eventually display proper PiP windows that stay above others automatically. Support for “overlay planes” was added, which can reduce CPU usage and power draw when displaying full-screen content using a compatible GPU. You can read more about these and many other new features in the Plasma 6.5 release announcement and complete changelog.

Brian Haidet, a scientist creating videos on YouTube under the handle AlphaPhoenix, showed off a camera in a new video that can capture footage of a laser pointer at the speed of light. The camera is an update on a previous design that could capture footage at one billion frames per second, but it comes with a major caveat: it can only shoot one pixel at a time.

Haidet’s camera is made from a gimbal-mounted mirror, two tubes, a simple lens, a light sensor and some Python code to tie it all together. Pointed at a laser pointer, the camera’s able to capture a beam of light at two billion frames per second, showing it smoothly traveling between mirrors, with speeds that vary depending on where the camera is in relation to the laser pointer. “Light moves about six inches, or 15 centimeters, per frame of this video,” Haidet says. “This beam of light is traveling at the Universe’s speed limit. Light in any reference frame will never move any faster or any slower than this speed.”

Brian Hadet

While it’s theoretically possible to create a more traditional camera that can capture footage at two billion frames per second, as Haidet explains, you can’t do it with the tools most people have in their garage. His solution was to capture one pixel at a time, and then tile that footage together to create something viewable. According to Haidet, “if all these videos are synchronized and we take many, many, many, one pixel videos, we can tile these videos next to each other and play them all back at the exact same moment and give something that looks like a video.” 

While it’s not the same thing as a true two billion frames-per-second camera, “that’s just a significantly more expensive way to do it,” Haidet says, “and it really wouldn’t get us any better of a result.”

Amid the chaos of the Trump administration’s haphazard job cuts and a mass exodus of leadership, the Food and Drug Administration is experiencing a slowdown of drug reviews and approvals, according to an analysis reported by Stat News.

An assessment of metrics by RBC Capital Markets analysts found that FDA drug approvals dropped 14 percentage points in the third quarter compared to the average of the six previous quarters—falling from an average of 87 percent to 73 percent this past quarter. In line with that finding, analysts noted that the delay rate in meeting deadlines for drug application reviews rose from an average of 4 percent to 11 percent.

The FDA also rejected more applications than normal, going from a historical average of 10 percent to 15 percent in the third quarter. A growing number of rejections relate to problems at manufacturing plants, which in turn could suggest problems with the FDA’s inspection and auditing processes.
