The ongoing story of bogus analytical data being submitted to the public OctoPrint usage statistics has taken a surprising turn with the news that a second plugin was being artificially pushed up the charts. At least this time, the developer of the plugin has admitted to doing the deed personally.

Just to recap, last week OctoPrint creator [Gina Häußge] found that somebody had been generating fictitious OctoPrint usage stats since 2022 in an effort to make the OctoEverywhere plugin appear to be more popular than it actually was. It was a clever attempt, and if it wasn’t for the fact that the fake data was reporting itself to be from a significantly out of date build of OctoPrint, there’s no telling how long it would have continued. When the developers of the plugin were confronted, they claimed it was an overzealous user operating under their own initiative, and denied any knowledge that the stats were being manipulated in their favor.

Presumably it was around this time that Obico creator [Kenneth Jiang] started sweating bullets. It turns out he’d been doing the same thing, for just about as long. When [Gina] contacted him about the suspicious data she was seeing regarding his plugin, he owned up to falsifying the data and published what strikes us as a fairly contrite apology on the Obico blog. While this doesn’t absolve him of making a very poor decision, we respect that he didn’t try to shift the blame elsewhere.

That said, there’s at least one part of his version of events that doesn’t quite pass the sniff test for us. According to [Kenneth], he first wrote the script that generated the fake data back in 2022 because he suspected (correctly, it turns out) that the developers of OctoEverywhere were doing something similar. But after that, he says he didn’t realize the script was still running until [Gina] confronted him about it.

Now admittedly, we’re not professional programmers here at Hackaday. But we’ve written enough code to be suspicious when somebody claims a script they whipped up on a lark was able to run unattended for two years and never once crashed or otherwise bailed out. We won’t even begin to speculate where said script could have been running since 2022 without anyone noticing…

But we won’t dwell on the minutiae here. [Gina] has once again purged the garbage data from the OctoPrint stats, and hopefully things are finally starting to reflect reality. We know she was already angry about the earlier attempts to manipulate the stats, so she’s got to be seething right about now. But as we said before, these unfortunate incidents are ultimately just bumps in the road. We don’t need any stat tracker to know that the community as a whole greatly appreciates the incredible work she’s put into OctoPrint.

Developing free and open source software can be a thankless experience. Most folks do it because it’s something they’re passionate about, with the only personal benefit being the knowledge that there are individuals out there who found your work useful enough to download and install. So imagine how you’d feel if it turns out somebody was playing around with the figures, and the steady growth in the number of installs you thought your software had turned out to be fake.

That’s what happened just a few days ago to OctoPrint developer [Gina Häußge]. Although there’s no question that her software for remotely controlling and monitoring 3D printers is immensely popular within the community, the fact remains that the numbers she’s been using to help quantify that popularity have been tampered with by an outside party. She’s pissed, and has every right to be.

[Gina] discovered this manipulation on June 26th after taking a look at the publicly available usage stats on data.octoprint.org. She noticed that an unusually high number of instances appeared to be running an old OctoPrint release, and upon closer inspection, realized what she was actually seeing was a stream of bogus data that was designed to trick the stat counter. Rolling back the data, she was able to find out this spam campaign has been going on since late 2022. Tens of thousands of the users she thought she’d gained over the last two years were in fact nothing more than garbage spit out by some bot. But why?

Here’s where it gets interesting. Looking at the data being reported by these fake OctoPrint instances, [Gina] could tell the vast majority of them claimed to be running a specific plugin: OctoEverywhere. The perpetrators were clever enough to sprinkle in a random collection of other popular plugins along with it, but this specific plugin was the one most of them had in common. Sure enough this pushed OctoEverywhere to the top of the charts, making it seem like it was the most popular plugin in the community repository.

So what do the developers of OctoEverywhere have to say for themselves? In a statement that [Gina] posted on the OctoPrint blog, they claim they were able to determine a member of the community had performed the stat manipulation of their own accord, but as of this writing are unwilling to release this individual’s identity. A similar statement now appears on the OctoEverywhere website.

On June 27th, Gina Häußge, the developer behind OctoPrint, informed us of an incident involving the OctoPrint usage stats. Gina had observed that the stats were being manipulated to boost OctoEverywhere’s rankings.

We took the report very seriously and quickly started an investigation. Using private community channels, we determined a community member was responsible for manipulating the OctoPrint stats. We had a private conversation with the individual, who didn’t realize the impact they were having but apologized and promised never to do it again.

From a journalistic perspective, it would be inappropriate for us to leap to any conclusions based on the currently available information. But we will say this…we’ve heard more convincing stories on a kindergarten playground. Even if we take the statement at face value, the fact that they were able to figure out who was doing this within 48 hours of being notified would seem to indicate this person wasn’t exactly a stranger to the team.

In any event, the bogus data has now been purged from the system, and the plugin popularity charts are once again showing accurate numbers. [Gina] also says some safeguards have been put into place to help prevent this sort of tampering from happening again. As for OctoEverywhere, it slid back to its rightful place as the 6th most popular plugin, a fact that frankly makes the whole thing even more infuriating — you’d think legitimately being in the top 10 would have been enough.

On Mastodon, [Gina] expressed her disappointment in being fooled into thinking OctoPrint was growing faster than it really was, which we certainly get. But even so, OctoPrint is a wildly popular piece of software that has become the cornerstone of a vibrant community. There’s no question that her work has had a incredible impact on the world of desktop 3D printing, and while this turn of events is frustrating, it will ultimately be little more than a footnote in what is sure to be a lasting legacy.

While 3D printers have evolved over the past two decades from novelties to powerful prototyping tools, the amount of support systems have advanced tremendously as well. From rudimentary software that required extensive manual input and offered limited design capabilities, there’s now user-friendly interfaces with more features than you could shake a stick at. Hardware support has become refined as well with plenty of options including lighting, ventilation, filament recycling, and tool changers. It’s possible to automate some of these subsystems as well like [Caelestis Workshop] has done with this relay control box.

This build specifically focuses on automating or remotely controlling the power, enclosure lighting, and the ventilation system of [Caelestis Workshop]’s 3D printer but was specifically designed to be scalable and support adding other features quickly. A large power supply is housed inside of a 3D printed enclosure along with a Raspberry Pi. The Pi controls four relays which are used to control these various pieces hardware along with the 3D printer. That’s not the only thing the Pi is responsible for, though. It’s also configured to run Octoprint, a piece of open-source software that adds web interfaces for 3D printers and allows their operation to be monitored and controlled remotely too.

With this setup properly configured, [Caelestis Workshop] can access their printer from essentially any PC, monitor their prints, and ensure that ventilation is running. Streamlining the print process is key to reducing the frustration of any 3D printer setup, and this build will go a long way to achieving a more stress-free environment. In case you missed it, we recently hosed a FLOSS Weekly episode talking about Octoprint itself which is worth a listen especially if you haven’t tried this piece of software out yet.
