If anyone actually manages to get Plasma Bigscreen working decently, please let me know how you did it. I was really excited when I first learned about it, but after considerable time tinkering, I gave up.

My first attempt was to install it on an old laptop. It boots up and looks good, but a large number of the built-in apps hang forever on their splash screen when you try to run them. I also couldn't figure out how to customize what apps appear in the carousels on the homepage. I'm not sure if that's because there truly is no way to do it or if the functionality is locked behind one of the apps that I can't launch.

The Plasma Bigscreen website indicates that it was designed to run on a Raspberry Pi 4, so I gave in and bought one in hopes that using the preferred hardware would work better. I followed the provided links to the latest Manjaro build of Bigscreen (which is over a year old) and installed it on my pi. Unfortunately, that build apparently suffers from a bug that prevents you from even getting past the login screen on first boot up. I don't remember the details, but I think it was some kind of "can't log in without setting a password" / "can't set a password until you log in" loop. Anyway, I found a forum post discussing the problem with no solutions found, so I gave up on the manjaro build.

My final attempt was to install an ordinary desktop Linux distribution on the pi and then use the package manager to install Plasma Bigscreen as an alternative desktop. This got me in, but there were still a bunch of broken apps. It was about this time that I also realized that the original Bigscreen concept seemed to lean heavily into voice control via Mycroft AI. Mycroft has gone through some major changes since the project launched, and I think these changes have resulted in basically all Mycroft related code in Plasma Bigscreen being broken. That may or may not be related to the other problems I had. I never got to experience a fully functional version of the software, so I have a hard time knowing what exactly is broken in what ways.

Anyway, that's my experience with Plasma Bigscreen. I hope this doesn't come across as hating on the project. It should be evident from the amount of effort put in that I really wanted it to work, but in the end I had to conclude that in its current state, it's badly broken with no sign of improvement or repairs.

If you were actually hoping to buy one but the rounded corners are a dealbreaker, then you may be interested to know that the DIY edition lets you mix and match the older display with the newer motherboards. Looks like opting for the older display even saves you $130 on the purchase price.

I know there's some controversy surrounding Brave as a company, and I'm not a fan of everything they do, but the goggles feature in their search engine is a really interesting attempt to give users more control over their search results.

The tool allows you to re-rank your search results according to custom rule sets. Each rule contains a regex style string to check against webpage URLs, and an instruction for what to do when a match is found. There are four basic types of instruction:

  1. Exclude matching URLs from your search results.
  2. Boost matching URLs so they appear higher in your search results than they otherwise would
  3. Downrank matches, causing them to appear lower in the results than they otherwise would.
  4. Highlight matches so they stand out in the list of results.

Brave has provided some premade rule sets (called goggles) that you can use right away, such as one that automatically removes all pinterest links, or another that boosts posts from tech related blogs. It's also relatively straightforward to create your own goggles, which you can either keep private or make public for others to find and use as well.

If you want to try it out for yourself you can go to search.brave.com and do a normal search for whatever you want. Then, on the results page, click the little "goggles" button just below the search bar. You'll be presented with a variety of premade filters along with a "discover more" button which sends you to a page with more information and filter options.

A university near me must be going through a hardware refresh, because they've recently been auctioning off a bunch of ~5 year old desktops at extremely low prices. The only problem is that you can't buy just one or two. All the auction lots are batches of 10-30 units.

It got me wondering if I could buy a bunch of machines and set them up as a distributed computing cluster, sort of a poor man's version of the way modern supercomputers are built. A little research revealed that this is far from a new idea. The first ever really successful distributed computing cluster (called Beowulf) was built by a team at NASA in 1994 using off the shelf PCs instead of the expensive custom hardware being used by other super computing projects at the time. It was also a watershed moment for Linux, then only a few yeas old, which was used to run Beowulf.

Unfortunately, a cluster like this seems less practical for a homelab than I had hoped. I initially imagined that there would be some kind of abstraction layer allowing any application to run across all computers on the cluster in the same way that it might scale to consume as many threads and cores as are available on a CPU. After some more research I've concluded that this is not the case. The only programs that can really take advantage of distributed computing seem to be ones specifically designed for it. Most of these fall broadly into two categories: expensive enterprise software licensed to large companies, and bespoke programs written by academics for their own research.

So I'm curious what everyone else thinks about this. Have any of you built or admind a Beowulf cluster? Are there any useful applications that would make it worth building for the average user?

I've been aware of pi-hole for a while now, but never bothered with it because I do most web browsing on a laptop where browser extensions like uBlock origin are good enough. However, with multiple streaming services starting to insert adds into my paid subscriptions, I'm looking to upgrade to a network blocker that will also cover the apps on my smart TV.

I run most of my self hosted services on a proxmox server, so I'd like something that'll run as an LXC container or a VM. I'm also vaguely aware that various competing applications have come out since pi-hole first gained popularity. Is pi-hole still the best thing going, or are there better options?

You might be interested in the pop-sci book Soonish: ten emerging technologies that'll improve and/or ruin everything. I haven't read it myself, but I've read the authors' other book about space colonization, and it was excellent so I would expect this one to be as well.

I mean, this is definitely going to be a disaster but I think the title and article here are a little misleading. The author implies that Warner Brothers is spearheading (and paying for) this venture, but I just read through the buzzword salad of a press release and it barely mentions them. The project is driven by an independent company that licensed the ready player one IP from WB. The whole thing very carefully avoids any details about money changing hands, but my guess is either that WB is getting paid, or they've negotiated a cut of any theoretical future profits. Of course, the chances of there ever being profits are slim to none, but I'd say at worst they're net $0 on the deal, and at best they actually made some money by getting paid up front. They might suffer some reputation damage if it becomes a real catastrophe, but as the author of the article mentioned they are billions in debt, so its probably a risk they're happy to take.

Suddenly I want to see a super smash bros knockoff where all the playable characters are public domain, and every January 1st they release an update with new characters that lost copyright protection in the past year.

I'm aware that the plastic handles probably disqualify these from being true "buy it for life", but the exciting thing for me is that they are relatively cheap and can be found on the shelf in most stores with an office supply section. It's an unfortunate reality that the vast majority of BIFL items are special order and cost several times more than their mainstream equivalent, so I wanted to shout out Scotch brand for maintaining such good serviceability on an item you can literally pick up at Walmart.

I just pulled apart a pair of these which was cutting horribly, gave each blade a couple passes on an oil stone, then reassembled and tightened them up with a drop of oil in the joint. They cut as well as the day they were bought, and the handles are still in good shape so I could see doing this several more times before I even have to consider replacing them.

This is the one I came here to say. For anyone living in or visiting Chicago, the Garfield Park Conservatory is a lovely place to spend a few hours on a cold winter day.

Youtube in has done a remarkably good job carrying the torch of high quality documentaries and educational content beyond the realm of traditional media. Science, art, technology, history. It's all there, and much of it meets or exceeds the quality of anything the old guard of cable TV channels ever managed to produce.

I'm actually only now realizing that some of the most established channels have been reaching a wide audience with consistent and high quality content for the better part of a decade, and yet I can't think of any who have successfully broken into more "traditional" media such as television or or even streaming services. That seems exceptionally strange to me. I mean, last month there were headlines about Netflix giving $55 million to an unproven director who proceeded to blow it all on expensive cars instead of filming the show he was hired to make. Who decides to hire that guy over any number of youtube creators who have spent the last ten years cranking out a short video a week along with occasional longer form projects, all with a small crew on a shoestring budget. I can imagine three possible reasons for this. No idea which one(s) could be the real reason, or if there's something else entirely going on.

  1. Hollywood^1^ is so insular that they don't even realize these people exist.
  2. Hollywood is so stuck in its ways that they refuse to believe these people could be successful running a larger production.
  3. Offers have been made, but those offers have been so restrictive that any number of youtubers have turned them down despite, one would assume, a large amount of money being on the table if they go along with it.

That last one in particular seems unlikely, but I do recall that the popular Primitive Technology channel went quiet for a year or more before abruptly coming back to life. Rumors swirled that he had been hired to turn the concept into a TV show, but the production company kept trying to change things and he eventually gave up and went back to doing it his way on youtube.

^1^ used here as shorthand for the more corporate and structured entertainment industry at large.

I remember reading a comment a while ago (on Reddit, ironically) which pointed out that SFW subreddits naming themselves [subject]porn are borrowing the wrong part from the word "pornography". "Porn" is from greek pornē meaning "prostitute", but the suffix -graphy means "to write" and is often used to indicate "the study of" the thing it's attached to (e.g. geography, cryptography, demography, etc.)

It would be more accurate, and perhaps less controversial, if these communities named themselves earthography, spaceography, unixograpy, etc. As an added bonus, the -grapy suffix is also prominent in "photography" which is appropriate considering that many of these communities are places where people share photos of the subject matter.

I read something a while ago that really put all these "ancient mysteries" into perspective: Modern humans with modern brains have existed in our current form for at least tens of thousands of years. During that time we've seen huge advancement as a society thanks to the accumulation and sharing of scientific knowledge, but any individual human today has no more brainpower than one living 10,000 years ago.

In other words, if we can sit around today and brainstorm a dozen different ways to build a pyramid with nothing but ramps and levers, there's absolutely no reason to think that the smartest builders in ancient egypt couldn't have come up withl the same ideas or better.

Attributing these achievements to aliens, or divine intervention, or anything other than raw human ingenuity is a disservice to our ancestors.

Slightly off topic, but as long as we're ranting about DNS...

Proxmox handles DNS for each container as a setting in the hypervisor. It's not a bad way of simplifying things, but if, hypothetically, you didn't know about that, then you could find yourself in a situation where you spend an entire afternoon trying every single one of the million different ways to edit DNS in Linux and getting increasingly frustrated because the IP gets overwritten every time you restart the container no matter what you do, until eventually you figure out that the solution is just like three clicks and a text entry box in the Proxmox GUI!

...Hypothetically, of course.

A garden that’s planted purely by aesthetic decisions is like a car with no engine. It may look beautiful, the stereo works great, but you’re going to have to push it up the hill.

This is a really informative article by Popular Mechanics describing how to effectively landscape with native plants, as well as the long term benefits you will see as a result.
