- Comment on As a novice at soldering, I now have an opinion about single-sided vs. double-sided breadboards 1 week ago:
::: spoiler You can still lift pads on many double sided boards. The real key is to use the highest heat capacity iron tip that can fit into the task at hand. The highest heat capacity tip will allow you to lower the tip temperature and transfer that heat effectively. With experience, you’ll also learn when to add supplemented heat due to ground planes and components.
If you ever get to the point of etching your own boards and then the extra even rarer step of attempting through hole plating. The biggest challenge is how to get the initial conductive bridge to form inside the hole itself. This usually involves something like a paint with graphite powder, or other chemical solution. Then the holes are electroplated with copper. The inside of these holes is not a particularly great surface to work with and has minor inconsistencies that are typical of a drill bit finish through a substrate like fiberglass. You’re likely to have a composite of different materials like the glass fiber and resin or even a plastic core with CEM. It does not make a very consistent substrate to coat, and the surface is hard to build consistently.
I come from owning an auto body shop twice, so I know all too well: liquid paints always pull away from sharp edges where they will be thinnest. Also, absolutely every finish is only as good as the layer it is on top of. If you put a $10k job on top of a pealing $500 job, it will fall apart and be nothing but problems within a year.
The qualities of the base coating that is used to initially bridge the top and bottom layers is what will largely determine the durability of rework.
Overheating the region will have a big impact on the outcome. With many stations and tips you’re likely to use too high of a temperature to compensate for tiny or the wrong tips. You need to get the lowest temperature possible and normalized on the whole connection quickly for rework. Preheating makes a big difference, as does eliminating any even small sources of moving air.
My favorite Hakko 900 series tip is the 900M-T-3.2D 4962615503139 (have it right beside me now in a sleeve of several). Genuine Hakko tips have far better plating that makes a difference too. I can do nearly every job with that tip turned in various orientations.
A hot air rework gun is helpful, just never cut off the cool down time prematurely. You can get a couple of the fake magic arm camera clamps for photography to make a handy holder for a cheap hot air rework setup. Use the counter clamp from the second arm to hold the gun.
A basic cheap hotplate from a thrift store is helpful for preheating too, even one that is only for warning with no temperature adjustment.
- Comment on Are anyone else's texts getting delayed after the RCS switch? 1 week ago:
Not sure of the exact issue but the best answer from Apple so far is that the issue is kernel related. I’ve tried every setting I can find and no luck. It could also be related to actual dual sim use. It could be carrier related, but it is less likely Android as I use Graphene OS.
- Comment on Are anyone else's texts getting delayed after the RCS switch? 2 weeks ago:
Apple is doing insane stuff with iMessage making SMS useless with Android. It is intentional manipulation. I’ve only seen it on some Apple kernels with the latest iPhone. My old man’s phone absolutely will not send or receive an SMS unless I message is manually turned off and then it won’t get iMessages. Apple has always been a shitty company, but this is next level insane. Just get and use the Signal app and ditch all the proprietary garbage and manipulative bs IMO.
- Comment on With Core ONE, Prusa's Open Source Hardware Dream Quietly Dies | Hackaday 2 weeks ago:
They haven’t been really open source for a long time. The move away from Merlin’s configurations based software and onto custom code that only a full time dev can effectively modify was a major shot against the roots of RepRap and the community around Adrian Bowyer that Joe was a part of and got him started.
Nothing lasts forever, but the move away from open source officially marks the end of me going out of my way to purchase from them or recommend them.
Long live the kit makers and sources like LDO and Voron. The community created the 3d printing hobby, not the companies, not some guy that throws beer parties with llamas in the Czech Republic.

- Comment on [deleted] 2 weeks ago:
That is all model loader code based stuff. You basically just need a bit of Python code that anyone can write, even you. You need to have a look at how the model must be addressed in format, then you find how the model loader code you are using creates the structured text and just insert your own modifications.
It is easier to add a second prompt window where you keep persistent information and just change it yourself. If you want the model to change that stuff, you need to look into building an agent.
I hacked around like this for awhile too, but evolved into using the notepad tab of Oobabooga Textgen WebUI and a Mixtral 8×7B model with a 32k context window. That model can deal with almost any detail you add in the context.
The thing is, the model may not feel satisfied with mundane and redundant details. Most of the time, believe it or not, those changes that you perceive as errors or inconsistencies are not actually errors. The model is fully aware that it is making those changes. There is usually an instruction about creativity, inspiration, or initiative that will cause the model to shift details like this.
My best recommendation is to openly discus the error in dialog with the model. They usually will talk about the issue if you call one out. Talking with AI is very different than with humans. Everything they say has meaning and functions beyond what is initially apparent. There are a lot of behaviors that involve certain patterns and keywords. You can even alter these behaviors by banning certain tokens/keywords. A good place to start is banning paragraph starting words for filler material. “So_” would be a good starting token to ban, as with AI, no sentence that starts with that token is worth reading. Other important words are twist, chuck, and cross. These are more flexible in their troublesome meaning and can manifest in multiple words like chuckles or across but still function the same inside the model.
If you get to this level of familiarity, the persistence of a storied interaction is more of a negotiation with the AI.
Another point of understanding is that the model does not know the difference between roleplaying characters it owns and you own or who is who. You or the model loader code is creating the name of the next character that the model generates for. Everyone in any story can be the model if it is asked to create the prompt.
So is I say, “Jake is super creative” or imply it somewhere in the prompt, and the model later thinks ‘Jake is rather bored and needs to be creative’ it is going to change something that satisfies that character profile even if it has never generated the output for character Jake.
Hope that helps some

This is a staged ad. It is meant to be a message to others in corporate America, and for marketing to convenient idiots to quote the Russian term.

I’m a better person with Adderall. I feel more like myself, like I escape a frustrating fog. I’ve been on it for ~14 years. It doesn’t seem to have the same effects on everyone.
Everything in life is ultimately brain chemistry and addictions. Most of the drugs in our chemistry soup are the substances the human body synthesises on its own. Biology is a funny thing. It can handle immense complexity, but can struggle with precision.
If you have the self awareness to seek out and optimise your brain or body chemistry where it might be lacking, I’d argue that you are the better person than someone that suffers through the deficiencies of their natural biology.
However, humans have a very difficult time assessing their own brain chemistry objectively without biases. It is both harmful and unsafe to self diagnose or self medicate without the assistance of someone that is trained to objectively asses your situation and needs.
- Comment on Westloki – 3D printed bicycle belt drive conversion (solid continuous loop belt on an unbroken bike frame) 5 weeks ago:
These are basically timing belts for cars. Inside the belt are usually metal or aramid fibers that prevent any elongation of the tooth pitch. A lot of the automotive aftermarket principals of a timing chain versus a timing belt drive apply exactly the same here. The belt lasts longer and operates dry with more accuracy over time.
- Comment on Westloki – 3D printed bicycle belt drive conversion (solid continuous loop belt on an unbroken bike frame) 5 weeks ago:
The positives of a belt drive are maintenance, and that it stays clean so they are most popular with commuters that do not want a dirty pants leg or newbie chain tat. They are only common on heavier bikes like short haul commuters in general and require a “broken frame” that is designed for them in the first place. The lack of transmission gearing means you need to either know exactly what gear ratio you need and deal with only having one speed or you need an internally geared hub. All internally geared hubs have monstrous weight to add. So in practice, you do not find many of these on the market. Even with an e-bike, you still need a geared transmission unless you have throttle control without pedaling.
On the other hand, for a hipster roadie, a fixie with a belt drive is some serious cred. Especially if they can dish it at the local group ride against people on flagship bikes.

- Comment on Why is removing stuck rings with dental floss painless for some people? 5 weeks ago:
::: spoiler A lot of it is from use too. My left and right hands have different sensitivities from playing guitar all my life. Auto body work also forces a person to dial in touch at a very atypical level, especially for a painter like myself. I’ve trained a few apprentices and even those with an initially poor sense of touch eventually dial in the skill. There is a level of imperfections in the final finishing steps where it is impossible to see the issue in oblique view due to the matte finish of primer/sealers. This is well after blocking and guide coats are no longer helpful. At this stage, there are still many imperfections that will create obvious errors after clear coat because the distorted reflections that may be present in the final gloss. These errors can be very color dependant. They can manifest in the way metallics settle within the color coat making the issue visible here as well. The worst color for reflective errors is black. With some whites a painter can get away with nearly any minor error at this stage without consequences as long as there is enough orange peel present in the factory finish.
Anyway, there are two tricks to finding late stage errors in the primer. The easy way is to use a wax and grease remover solvent wiped liberally across the panel. This will temporarily create a clear coat like gloss that will show exactly what the final reflective properties will be like after clear is applied. This is always the final test before you shoot anything. However, doing this a whole bunch of times just because you can’t feel the issues is very amateur noob territory. Any skilled painter learns how to touch a panel in a sweeping feel using the center pad of each finger tip and sliding a hand along the surface in a way that one can feel even the most subtle of errors. I can feel the reflection–no joke.
A painter spends a ton of time wet sanding by hand too. This leads to sanding off most of the outer skin on your hands. In fact, when I was really busy and working 12-14 hour days, I had to quit when my fingers started to bleed. They actually bleed the pattern of your fingerprints when you sand through them with a fine grit over time. The thin skin and heat sensitivity it creates helps to dial in the skill.
That is my long bla bla bla about why, in my experience, anyone can dial in their sensitivity and awareness as a skill. When I worked on heavy equipment or in the machine shop, I had tough callused hands; with auto body thin soft and sensitive, and after all my crashes and battles with cars on a bicycle, like a seriously scared up brawler.

- Comment on Is lemmy really any different from reddit? 5 weeks ago:
I don’t find myself making spontaneous buying decisions for frivolous nonsense in my life in general when I stick around here. All of my purchases are due to my needs and research only.
Physical disability with social isolation gives one a potential ability to more deterministically decipher where and how interactions influence them. I have less inputs and influences and tend to remember what was suggested or peripheral to my intentions. I got into a lot of stuff over the last 10 years that, when I look back, I really don’t know why I did them. I know my surface reasoning, but like, why was I following those people and spaces in the first place–that kind of meta logic perplexed me. When I quit YouTube and switched to newpipe/reddit, those random tangents were drastically reduced. When I quit reddit they went away entirely. It is entirely speculation, and probably borderline paranoia, but I probably only bought stuff on AliEx because it seemed like everyone on YT was buying from there. I can’t say it was all bad or unwanted or anything like that. I can say I got stuff I didn’t need or use.
I still explore new interests and projects I feel like trying when I see them here, but I have yet to feel influenced in a way that hints at manipulative intentions.
I’ve seen people try with disingenuous arguments that have 5-10 upvotes instantaneously. I’ve seen posts that have supporting corpo replies seconds after posting or where a typical type of comment for Lemmy gets a large scale negative response quickly that is obviously not genuine or typical behavior. Unlike reddit, these seem so blatantly obvious here that I block the posters and commenter immediately. Blocking here is rather effective and blocking a lot of users makes for a pretty pleasant experience unlike anything I ever had on reddit. This is my only outlets to contact other humans and I feel rather balanced with it and self care. That is more than I can say about reddit.
- Comment on Pineapple pickle 5 weeks ago:
Just pineapple in a ~3% salt brine that came out tasting like a pickle.
I did pineapple once before but it was a tiny amount inna little jar and it came out fantastic. I was curious how a bunch of whole trimmings might turn out with this one. I’d say it was not great. However, it was a little old and had some very small moldy spots on the outside that I discarded, washed the rest, and went with. The one I prepared today is much more fresh and no spots of mold so hopefully that comes out better.
I probably should have stopped the last one a little sooner too. It was slowing down and the CO^2^ bubble size was getting larger with each burp. I think it might be better when it still fizzes like champagne. At the peak, it fizzed to a head that filled nearly half of a 1L jar of head room. So far, pineapple is the only ferment I have tried that is this active, like it could probably blow a jar within 24 hours if left sealed without a check valve or burping.

- Comment on For states on the coast with excess solar energy why don't they invest in water desalination and pump that water back upstream? 1 month ago:
Land acquisition cost and not in my backyard’ers. At least here in Southern California. There is no chance that a loosely regulated and toxic high salinity waste water plant would get past public and environmental scrutiny. The only really viable areas are the last local refuges for many.
Like from Mexico to Santa Barbara, the camp Pendleton Marine Corps base is one of the only viable spots. The decommissioned nuclear power plant would be one of the mostly likely spots to build such a facility, but that is surrounded by a state park and some of the most prised undeveloped local surf real estate. Many municipal and commercial projects have vied for that land, but there is fierce local opposition from a wealthy and very politically well connected public.
There has been occasional talk about opening up the Pacific side of the 5 freeway to public development as this is some of the federal government’s most valuable real estate. Even if this happened, that would become one of the most elite places to live in the country.
Few people know this, but the Southern California coast around Orange County and North of San Diego is a spot of rare deep ocean upwelling. There is a micro climate here within a couple miles of the coast that is regulated by the ocean upwelling maintaining temperatures. It is always cooler in the summer and warmer in the winter here and almost always between 50°F and 80°F even when a few miles away it can be 40°F-100°F. This is one of the main reasons why real estate in these areas is so high.
