Jenny’s Daily Drivers: Slackware 15

July 10, 2023 by Jenny List 53 Comments

As a recent emigre from the Ubuntu Linux distribution to Manjaro, I’ve had the chance to survey the field as I chose a new distro, and I realised that there’s a whole world of operating systems out there that we all know about, but which few of us really know. Hence this is the start of what I hope will be a long-running series, in which I try different operating systems in my everyday life as a Hackaday writer, to find out about them and then to see whether they can deliver on the promise of giving me a stable platform on which to earn a living.

For that they need an internet connection and a web browser up-to-date enough to author Hackaday stories, as well as a decent graphics package. In addition to using the OS every day though, I’ll also be taking a look at what makes it different from all the others, what its direction and history is, and how user-friendly it is as an experience. Historical systems such as CP/M are probably out of the question as are extremely esoteric ones such as the famous TempleOS, but this still leaves plenty of choice for an operating system tourist. Join me then, as I try all the operating systems.

A Distro From The 1990s, Today

A desktop mini tower PC with monitor showing the Slackware boot screen — The Hackaday test PC gets its first outing.

When deciding where to start on this road, there was an obvious choice. Slackware was the first Linux-based distribution I tried back in 1995, I’m not sure which version it was , but it came to me via a magazine coverdisk. It was by no means the first OS that captured my attention as I’d been an Amiga user for quite a few years at that point, but at the moment I can’t start with AmigaOS as I don’t have nay up-to-date Amiga-compatible hardware.

July 2023 also marks the 30th anniversary for the distro making it the oldest one still in active development, so this seems the perfect month to start this series with the descendant of my first Linux distro. Slackware 15 comes as a 3.8 GB ISO file download for 64-bit computers, and my target for the distro was an old desktop PC with an AMD processor and a big-enough spinning rust hard disk which had been a high-end gaming system a little over ten years ago. Not the powerhouse it once was, but it cost me nothing and it’s adequate for my needs. Installed on a USB Flash drive the Slackware installer booted, and I was ready to go.

Hackaday Links: July 9, 2023

July 9, 2023 by Dan Maloney 8 Comments

Good news this week from Mars, where Ingenuity finally managed to check in with its controllers after a long silence. The plucky helicopter went silent just after nailing the landing on its 52nd flight back on April 26, and hasn’t been heard from since. Mission planners speculated that Ingenuity, which needs to link to the Perseverance rover to transmit its data, landed in a place where terrain features were blocking line-of-sight between the two. So they weren’t overly concerned about the blackout, but still, one likes to keep in touch with such an irreplaceable asset. The silence was broken last week when Perseverance finally made it to higher ground, allowing the helicopter to link up and dump the data from the last flight. The goal going forward is to keep Ingenuity moving ahead of the rover, acting as a scout for interesting places to explore, which makes it possible that we’ll see more comms blackouts. Ingenuity may be more than ten-fold over the number of flights that were planned, but that doesn’t mean it’s ready for retirement quite yet.

99% Partspiration

July 8, 2023 by Elliot Williams 37 Comments

Thomas Edison once said that genius was 1% inspiration and 99% perspiration. That doesn’t leave much room for partspiration.

I’m working on a top-secret project, and had to place a parts order on AliExpress with a minimum order quantity of five in order to get decent shipping times. No big deal, financially, and it’s always great to have spares as backup for the ones you fry.

But as I started lighting up the little round smartwatch displays to put them through their paces, I started thinking of all sorts of ways that I could use something like this. I had no idea how easy to drive they were, or frankly, how good they looked in person. When you get a round display in your hands, you find that you need dial indicators everywhere.

And then my son came by and said “Oh neat. I want one!” and started thinking up all sorts of gizmos that I could put them in. Two of them would make awesome eyes, and he’s been on a chameleon kick – the animal, you know. So we’re looking for chameleon eye animations online.

And all of a sudden, I have more projects lined up than I have remaining screens. I’m calling this phenomenon “partspiration”. You know, when you figure out how to use something and then you see uses for it everywhere? Time to place another Ali order.

Gearing Up for the Hackaday Prize

And don’t forget, we just started the next round of the Hackaday Prize: Gearing Up. In this challenge round we want to see your best DIY tools, jigs, and workflow accelerators. Custom reflow plates, home-built power supplies, or even software tools – as long as it helps you get the job done, it has a place here. You’ve got until Aug. 8 to get your entry finished, but head on over to Hackaday.io and get started now.

Retrotechtacular: The Nuclear Cruise Ship Of The Future Earns Glowing Reviews

July 7, 2023 by Al Williams 33 Comments

The average modern cruise ship takes about 250 tons or 80,000 gallons of fuel daily. But can you imagine a cruise ship capable of circling the globe fourteen times before it needed to top off? That was the claim for the NS Savannah, a nuclear-powered cruise ship born out of President Eisenhower’s “Atoms for Peace” initiative.

The ship was a joint project of several government agencies, including the US Maritime Administration. With a maiden cruise in 1962, the vessel cost a little more than $18 million to build, but the 74-megawatt nuclear reactor added nearly $30 million to the price tag. The ship could carry 60 passengers, 124 crew, and over 14,000 tons of cargo around 300,000 nautical miles using one set of 32 fuel elements. What was it like onboard? The video below gives a glimpse of nuclear cruising in the 1960s.

Hackaday Podcast 226: Ice, Snow, And Cooling Paint In July

July 7, 2023 by Al Williams 3 Comments

This week, Editor-in-Chief Elliot Williams and Al Williams shoot the breeze about all things Hackaday. We start off with some fond remembrances of Don Lancaster, a legendary hardware hacker who passed away last month. There’s also news about the Hackaday Prize (the tool competition) and a rant about fast computers and slow software, a topic that drew many comments this week.

In the What’s That Sound event, Al proves he’s more of a Star Trek fan than a videogamer. But there were plenty of correct answers, but only one winner: [Wybrandus]. There’s always next week, so keep playing!

Elliot may be dreaming of cooler weather since he talks about ice sculptures, snow measurements, and a paint that can make things cooler. We don’t know what Al is dreaming about, but he is worried about his fuses, and the ins and out of open source licensing.

Along the way, you’ll hear about personal vehicles, sky cameras, and zapping weeds with extreme solar power. As usual, there is an eclectic mix of other posts. What has the Hackaday crew been up to? Field trips! Hear about Dan Maloney’s visit to the SNOTEL network to measure snowfall and a report from Al and Bil Herd’s trip to the Vintage Computer Festival Southwest.

What to read along? The links below will get you started. Don’t forget to tell us what you think in the comments!

Or, download a copy for posterity to file away in your archive.

This Week In Security: Bogus CVEs, Bogus PoCs, And Maybe A Bogus Breach

July 7, 2023 by Jonathan Bennett 3 Comments

It appears we have something of a problem. It’s not really a new problem, and shouldn’t be too surprising, but it did pop up again this week: bogus CVEs. Starting out in the security field? What’s the best way to jump-start a career? Getting a CVE find to your name certainly can’t hurt. And as a result, you get very junior security researchers looking for and reporting novel security vulnerabilities of sometimes dubious quality. Sometimes that process looks a lot like slinging reports against the wall to see what sticks. Things brings us to an odd bug report in the OBS Studio project.

A researcher put together a script to look for possible password exposure on Github projects, and it caught a configuration value named “password” in a .ini file, being distributed in the project source. Obvious credential leak in Git source, right? Except for the little detail that it was in the “locale” folder, and the files were named ca-es.ini, ja-jp.ini, and similar. You may be in on the joke by now, but if not, those are translation strings. It wasn’t leaked credentials, it was various translations of the word “password”. This sort of thing happens quite often, and from the viewpoint of a researcher looking at results from an automated tool, it can be challenging to spend enough time with each result to fully understand the code in question. It looks like this case includes a language barrier, making it even harder to clear up the confusion.

Things took a turn for the worse when a CVE was requested. The CVE Numbering Authority (CNA) that processed the request was MITRE, which issued CVE-2023-34585. It was a completely bogus CVE, and thankfully a more complete explanation from OBS was enough to convince the researcher of his error. That, however, brings us back to CVE-2023-36262, which was published this week. It’s yet another CVE, for the same non-issue, and even pointing at the same GitHub issue where the alleged bug is debunked. There’s multiple fails here, but the biggest disappointment is MITRE, for handing out CVEs twice for the same issue. Shout-out to [Netspooky] on Twitter for spotting this one.

ITER Dreams And The Practical Reality Of Making Nuclear Fusion Work On Earth

July 6, 2023 by Maya Posch 52 Comments

Doing something for the first time is tough. Yet to replicate the nuclear fusion process that powers the very stars, and do it right here on Earth in a controlled and sustained fashion is decidedly at the top of the list of ‘tough’ first times. What further complicates matters is when in order to even get to this ‘first’ you also add in a massive, international construction project and a heaping of geopolitics, all of which is a far cry from past nuclear fusion experiments.

With the International Thermonuclear Experimental Reactor (ITER) as the most visible part of nuclear fusion research, it is perhaps little wonder that the recent string of delays and budget increases is leading some to proclaim doom and gloom over the entire sector. This ironically in contrast with the recent news from the US’s NIF and its laser-based inertial confinement fusion, which is both state-funded and will never produce commercial power.

In light of this, it feels pertinent to ask the question of whether ITER is the proverbial white elephant, or even the mausoleum of international science that a recent article in Scientific American makes it out to be. Is fusion research truly doomed to peter out amidst the seemingly never-ending work on ITER?
