Hard to say for sure. He’s on Facebook so I don’t have a way to see what he posts, but my wife still has an account there and said he’s in some of the same groups as her. She’s pretty aware of what he’s posting and they’ve actually had conversations in person about the whole immigration thing. The rest… yeah I just don’t know.

This started on Wednesday, almost immediately after Trump’s victory was announced. By Friday it was already being reported in grade schools because asshole parents enjoy raising asshole sons, and Trump tells people that it’s ok to be the absolute worst human being they can be.
I have a friend who is a hard Republican. We generally don’t talk politics, but after this started last week he was posting things online being offensive towards women and POC (and the whole “illegals took my job and healthcare”) so I finally had to call him out. His response was basically that he wasn’t aware of any increased discrimination happening against women, therefore he didn’t believe it was happening. I’ve known the guy for 40 years but this may be the thing that breaks our friendship. He claims to be an advocate for people’s rights yet he is painfully unaware of the world around him.

Seems like a good opportunity to remind folks about the Kiwix project, which allows you to download local private copies of select information such as Wikipedia. It was originally created to provide offline access to content for countries that were otherwise blocked, but events like this have sparked some recent discussion about archiving older files to preserve history.

That’s a shame to hear, but yeah they’ve certainly changed since I signed on. Not that I expect any other to be better at this point.
- Comment on T-Mobile, AT&T oppose unlocking rule, claim locked phones are good for users 4 weeks ago:
It’s weird to see T-mobile taking this stance. I switched to them years ago because they were one of the few that supported unlocked phones, and even offered them for sale. Their policies might have changed on this, but I just bought an unlocked phone off Ebay this Summer and all I needed to do was pop my sim card into the new device. Hell I had to specifically install the visual voicemail app because there wasn’t any bloatware on the phone when I got it. So I guess I’m not following what their complaint is about?
- Comment on Internet Archive breached again through stolen access tokens 4 weeks ago:
Most of us can’t afford the sort of disk capacity they use, but it would be really cool if there were a project to give volunteers pieces of the archive so that information was spread out. Then volunteers could specify if they want to contribute a few gigabytes to multiple terabytes of drive space towards the project and the software could send out packets any time the content changes. Hmm this description sounds familiar but I can’t think of what else might be doing something similar – anyone know of anything like that that could be applied to the archive?

Discrediting someone usually has a goal of pushing customers to another source though. There is no other source of this information, so what would be the point?

OK cool, now if only you had a ship to go get the asteroid so you could make a ship. My last point still stands though, if it were really that easy…
- Comment on I'm a reasonably well educated human living on Earth. What's to stop me from replicating starship parts until I can make my own Starfleet? 4 weeks ago:
Raw material, I would imagine. I don’t remember exactly how replicators work in the Star Trek universe, but they either rely on energy, a raw base material, or both. You can’t create something out of nothing so you would need a significant supply chain to produce your fleet.
If it were that easy, every rogue organization in the galaxy would have already done it before you.

Sorry, just because you’re not capable enough to work with something that wasn’t completely fine-tuned for you at the factory doesn’t mean many of the rest of us have any problems with these machines. I do manual bed leveling and I can walk away from my printer for a year, turn it on, and pop out as good of print as the previous time it was used. How well does your “real” printer work after a year of neglect and with all the fancy gizmos turned off?
- Comment on Could use some help. 1 month ago:
Hmm I’m out of ideas then, sorry. Still wouldn’t hurt to do a single-layer test print (there are various models that put squares all around the bed) just to see how that’s looking. If the issue had been confined to one side or one corner it might have been a mechanical issue, but random areas makes it a lot harder to figure out.
If I remember right, jerk settings should be rather small, like single-digits, but I think calibrating your e-steps will go a lot further for cleaning up the prints.
One other step (and of course I cannot remember what this is called) is related to calibrating the filament ‘pressure’ along each path. It takes a bit of work to set up but the goal is to create a profile so you get a perfectly consistent amount of filament extruded through the entire length of a path, which compensates for excess amounts at the beginning and end of each path, or too little extrusion through the middle. You might even have to compile your own firmware to enable it if there’s not an option in Marlin to turn it on from the software (I was compiling my own anyway for a DIY direct-drive extruder), but it really does make a difference and it’s a set-and-forget thing that you only really need to do once.

Creality bases are notoriously NOT flat although I’ve heard their quality has improved over the years. I have one of the 1st-gen Ender 3 Pro machines with a terrible dip in the aluminum base. One nice thing about a thicker bed material is that you can use discs of aluminum foil the shim the base. I started with a glass bed and 13 layers of foil to get the glass reasonably flat. I have since moved to 3mm G10 with a PEI sticker which is working pretty well (in case you want to try PEI again). I found some scrap G10 material on ebay and chopped it with a table saw, sanded all the edges, then got a PEI sheet that was 10mm wider than my bed to allow for some slop. Putting down the stickers is a lot easier if you have someone helping you. Then trim the overhang and you’re ready to go.

Yeah that’s a pretty tight range for the bed leveling, shouldn’t be causing any issues then. OK another possibility here… the failing prints, are they on the left side, right side, one specific corner, or does it tend to move around between prints?
E-steps varies per extruder, not per manufacturer. What they recommend will get you close but there will always be some variance. On my printer Creality recommended a setting of 93 but my measurements put me up around 98, so quite a difference. Are you still using a bowden tube style extruder or did you upgrade to a direct drive? And is your filament spool mounted on top of the printer (if so, what guides have you added for the filament path), or did you move it off to the side?
Erg sorry, jerk is probably what you’re looking for here. It’s been awhile since I did much printing so I keep confusing the terms.

Belt tension should be tight enough that you can strum it and hear a tone. It’s possible to tighten a belt TOO much, which causes extra stress on the motors. This would result in the motors being physically very hot. However if these were both printed at the same time, that wouldn’t be the issue here.
I wonder, how level is your bed? Yes yes, you have a bltouch and all that, but you still need to manually get your bed relatively level. Were these two prints next to each other or on opposite sides of the bed? How did the other prints in the same batch compare (like was there an obvious pattern of failure from one side to the other)? The bad print looks to me like the nozzle is too close, so it might be interesting to see what your first layer looks like in a test across the bed.
Even in the good print there’s some blobbing at the end of each path and the main surface should be the same height as the walls around the cutouts. Did you calibrate your E-steps? It kinda looks like you’re pushing out a little too much filament. depending on your slicer options, you may also check acceleration to slow down the head at the end of each path, which can help give the whole path a more uniform output.
One other consideration, although not as likely… Warm up the bed and check to see if all areas feel like they’re about the same temperature. If part of the heating element went bad then maybe you’re over-heating one part to compensate for a lack of heat on the rest of the bed. I only mention this because the bad print looks like it has a slant to it, but that could be an illusion of the photo.

I’ll have to check it out, thanks for the link!
Yeah this article is really long, and a lot of it is over my head (especially the math), but they have brought up several interesting points and provided a much easier-to-understand model of the holographic universe. I mentioned this theory in another post here a few months ago and was basically shut down with claims that this wasn’t even possible and the theory had been long-discounted, and yet here we are with modern work still plugging away at the concept. It makes me appreciate just how much hell all scientists go through when they posit theories that contradict other people’s personal beliefs.

I’ve also read about the John Deere issue as a leading instigator of right-to-repair laws. They weren’t able to provide authorized local repair techs when a tractor breaks down, so farmers were stuck waiting 1-2 weeks for someone to show up while crops were rotting in the fields (think of how fast your fresh fruit rots in your kitchen and then imagine dozens of fields of that crop going to waste). And the biggest insult was when the repair tech drove into town for a $5 part that the farmer had already identified but couldn’t replace because of manufacturer lockouts.

- Comment on ISPs tell Supreme Court they don’t want to disconnect users accused of piracy 1 month ago:
So Sony wants to punish ISPs for continuing to “allow” illegal things to happen? Hmm remind me again which company it is that has had so many data breaches that users have come to just expect it? Sounds to me like if they are allowed to pursue attacking internet providers then they themselves should start seeing lawsuits for continuing damages until such time as Sony is able to successfully recover all stolen personal data and other parties can no longer use it for profit.

Hard to say for sure. They may have legitimately found something, but my experience with McAfee products has been abysmal. The last time I dealt with it, someone had the full paid version of their virus scanner which was up to date but wasn’t finding anything. I ran the free version of AVG and found over 200 items (mostly trojans and other malware). Their research may be valid, but I certainly wouldn’t trust any of their software to find even widely-known issues.

Now there’s an oxymoron. Let me know when they can write a virus scanner that works.

After the string of bad decisions he’s already made with this company, what makes you think he’s able to make good choices now? He has an echo-chamber where nobody can tell him to GTFO and that’s literally the only thing he’s ever getting out of it. It’s kinda like if someone paid an obscene amount of money for a junker car, then paid 10x that amount to put vanity plates on it.
- Comment on Yelp files lawsuit against Google 2 months ago:
There’s definitely been a lot of talk about the whole “pay us and we can make that bad review from someone who wasn’t your customer just go away.” Some say that never actually happened, and yet I was IT support for a small business who contacted Yelp to find out why non-customers were allowed to leave bad reviews and they were directly told that for a fee those reviews would be removed.
Sorry, I just realized I crossed up my evil businesses. Yelp did the whole protection-racket thing, it was LinkedIn that hacked people’s computers and keep sending out emails in their customer’s names (“I heard about this great company, you should check them out…”).
