Let me know when they create an alternative to transformers, pytorch, and create a tokenizer without the Open AI QKV hidden layers of alignment. That is where all the fuckery is happening. This is standard and used for all models. It is totally proprietary and a primary reason why they are "open weights" but not Open Source.

Advice on music player devices?

On that level, maybe invert your mindset and look in Maker spaces. Search by hardware like ESP32. You will likely get better (different) results if you search for devices that target EE students instead of those that target Makers in general. Like it is well known that Texas Instruments will send free samples of most common chips requested, to anyone with a .edu email. Projects on hardware like a Beagle Bone tend to be more advanced than more common Maker hardware. While a BB is like half of a Rπ in terms of hardware architecture, if a purpose made device is created without all of the extra overhead fluff, it is pretty good. The STM32 H7 stuff tends to have advanced projects at the handheld gaming level. The Nordic BT BLE chips are usually more popular with the advanced crowd.

You might look at the hardware commits for Micropython or Circuit Python for people adding DACs or other peripherals. These are likely to lead to their project spaces.

I've seen someone doing a drive swap on an old iPod to SSD and a software chain, but I think that was still only doing the Apple compatibility thing.

OpenWRT is not a bad place to look either. Any small embedded Linux device is likely to run on OpenWRT, so you may find something interesting just by shopping their hardware support and commit history.

Advice on music player devices?

I know, seems like a lot, but it really isn't if you just try it once. It is the same routine every time.

FOSS has no marketing department.

Why do you need a launcher? (asking older gamers actually)

I may check out this GOG eventually. Accounts, subscriptions, micro transactions, and criminal proprietary extortion are why I stopped gaming for the most part. For me, it has been full-source or fuck off for a long time. I cannot fix stupid in anyone else but me. I will not support criminal extortion and bank account skimming scams. They only exist because people have no real moral depth and self respect to say no.

When buying hardware in the present age, shop for FOSS software you want to run first. Then, clone the git in full. Finally, use the gource package to create a visual tree video that plays against the commit history. This will show you who is getting their pulls merged, how often, and how they contribute to the project.

What you're looking for is who is consistent, and what they are using for hardware. It will always be obvious on larger projects. They will make little tweaks and changes a bunch between the hardware and software.

You may see stuff like company employees and subcontracting devs come in and make large commits that support some specific hardware, but if you watch carefully, these are only a handful of commits, and then they never return. They likely had a checklist in a contract, completed it, and got paid. They will never return. Likewise, if one of the main devs gets a new device, they will shift to it and you're unlikely to see them make any further commits to the old stuff. The timespan between this transition infers much about the state of the old device support. Maybe just ask them why they switched and what is missing on the old stuff, or just cd to the hardware supporting directory and do $ grep -rin todo or similar types of stuff like code comments or words like hack or need.

Hardware specs and advertising nonsense are worthless and irrelevant. Don't let highway robbers dictate your expectations. The only products that exist are those with FOSS support, so start with the FOSS and ignore everything else as criminal warlords. Who gives a fuck what products and deals the proprietary fascists churn out of Auschwitz or a Palestinian camp.

If everybody at ICE protests showed up with masks and a gun would there be more or less violence?

More. The larger the group, the more distributed the intelligence, and the larger the chance that someone with unmitigated mental health problems are present.

Is it normal that you feel very shaky as soon as you start to get hungry?

I do the shaky thing too, but I think it is just psychological tbh. At calorie crash levels of no blood sugar during extreme endurance sports, it is totally different. It is like someone straps lead weights all over your body. Everything feels heavy and nearly impossible to move.

There is probably some kind of dynamic regarding different types of sugar in the system that cause the shakiness.

Your brain ONLY works on sugars. So calorie crashing, like hitting the wall, is when your body has to start cannibalizing your own muscles for sugar to fuel the brain. I've never been anywhere near that level except on a bike after 4+ hours and 60+ miles. You feel like a puddle, and joints are like bending copper wire. There is no shakiness in that state.

The hidden engineering of airport runways: Engineered Materials Arresting Systems

Anyone here ever driven in a runaway trap system?

I was mildly scared of them when I was getting my commercial driver's license ages ago. I was looking at potential jobs involving cranes or an excavator and lowboy. When a typical tractor trailer is fully loaded, you only have 3-4 full hard presses on the brakes before you lose them. Air brakes are inverted. The unpowered brakes state is fully engaged. The pneumatics are holding back the shoes; unlike typical cars that are pressing the friction material into a surface using hydraulics. When a truck fully engages the brakes, it lets all the air out. Then the reserve is used to refill the system to disengage. The engine's compression is a primary component of the braking system. However, it is a manual transmission. Unlike manual cars, these do not have synchromesh (small clutches that spin up the secondary gear shaft to match the primary shaft speed). If you miss a shift, you only have around a 50-75 RPM window where shift will mesh at all. On top of that, the engine only revs 2k-3k RPM, so the transmission is usually an 8 speed with 2-3 splitters. That means there are 16-24 speeds total, and for any given speed, only one little shift window exists. I was scared of big downhills. When a truck is fully loaded, going down hill, and you've got to shift for engine braking, it can feel about like someone is fully depressing the accelerator in a regular car. That shift window passes super fast. One can rev match the engine to a small extent, but it is still easy to miss in an unfamiliar rig. You are more focused on staying in the lane when every visual indication you're used to in cars is missing. Like you feel much larger than the lane and you only have around half a meter of extra margin split on both sides of the truck when driving minimum width lanes. So you miss the gear mesh, now you hard press the brakes to get the speed somewhere low where you are able to find a gear. Miss like that 3 times in a few minute span, and you're likely to run out of air. That slams on the brakes, but that is not enough to stop a fully loaded truck on grades steeper than 5-6%. It is why the signs exist warning about the grade. You must use the engine AND brakes at these grades, managing the air levels in concert with the RPM and gear selected.

Anyone here ever fucked that up, or been in to a runaway ramp or engineered stopping surface?

Why can people see who upvotes and who downvoted post on Lemmy?

A disorder is a function that causes disruptive distress or deviation from nominal behavior.

In abstract, I have posited a claim, and then shown how that claim is backed by associative social norms. I am attacking the normalization of anonymous negative behavior at a foundational level. I'm attacking the ethics of the developers that created this system in the first place. I have exemplified how this same behavior is in opposition to human social norms. I have shown its weaknesses in terms of political impact. I have posited a deeply unethical use case of why such a system would be implemented in the first place despite the malevolence. Finally, I have shown how it is destructive and harmful to everyone through statistical analysis using game theory.

The abstraction is not targeted in any way at people with mental health disorders. I am showing how the feature itself is a disorder or catalyst for disorderly behaviors.

I have actually tried really hard to remove any forms of bias or personal attacks from my dialog over the last decade or so. Like in this case, I'm actually arguing for positive constructive interactions in a more socially aware architecture. I want to remove the nominalized negativity. It was a mistake to make a space where people are able to abuse others, to manipulate, and to cause harm without social consequences as a feedback mechanism. It is a particularly sharp prejudice to experience when one is in near total social isolation from stuff like physical disability. Allowing people with no independent ethics to treat a space like this as a sadistic release valve for turgid eristics is simply wrong.

On pyfed, I see your overall "attitude" by default. This is the percentage of positive to negative voting interactions you have had recently. You are presently at 68%, which is rather low.

The activitypub protocol is not at all private. Anyone with a server and admin account is able to see all of these details.

Anonymous negativity is actually rather mental and should not exist in any democratic or ethical sense. You have a right to all information, a right to error, a right to skepticism, and a right to protest in nonviolent forms aka the right to offend others. Anonymous negativity is a violation of freedom of information and anti-egalitarian. Everyone has a right to confront their accuser with transparency.

If you have something to say, you should have the decency of stating it. Downvoting is a mental disorder. It is like people that use four letter expletives to express themselves when they lack the intellectual depth to articulate their thoughts. It only really exists as a corrupt means of artificially influencing behaviors for commercial and political means.

Is it ethical or reasonable to walk up to a stranger and give them negative feedback. Let's say you see a man exit his car to walk into a store. Should you have a right to leave an anonymous message on his car about the style of his shirt? Doing such nonsense will get you labeled a halfwit or worse. Take any real life circumstances and transpose this behavior. It is completely unethical nonsense.

"Trust" as a mechanism, is the primary tool of authoritarians and fascists. That is trash. Democracy and community are built with open transparency and accountability. One is a coward. The other will engage the dialectic and has nothing to hide. My "attitude" is 100% now. I rarely downvote because the behavior fails at fundamental game theory and the prisoner's dilemma. Negative feedback is incapable of creating positive outcomes. It always brings everyone down. So if you are going to be negative, at least do so constructively in a useful way by articulating your thoughts in text.

Trying to design a simple photo frame. Please help me understand these print issues.

Did you see I wrote that comment into a spoiler to shorten it in the post replies so it is not a wall of text? Sorry if my thoughts are hard to follow at times. I write in an abstract rough draft like format. I wrote several tips and how I approach a problem like this.

Trying to design a simple photo frame. Please help me understand these print issues.

Honestly, it is a bit of a noob design, and I do not mean that in any kind of negative or insulting way whatsoever. The main issue here is how you are thinking in terms of other materials and processes. Every product is primarily constrained by the manufacturing process. The design aesthetics are constrained by this process. The trick is to understand these constraints well enough to make something aesthetically pleasing within the process. To be fair, ~95% of designs shared and printed have this type of issue. Your design here looks like something I would make out of brass sheet and brazing. There is nothing fundamentally wrong with the approach. I see what you were trying to do.

The floating thin sections on layers, lack the flow consistency to maintain temperature regulation of the heat block. The heater cartridge in the print head is managed by a PID control loop. This will always have some overshoot and undershoot of temperature when the flow changes substantially. There are a number of contributing factors to this issue in the printer hardware design. I could go into a lot of depth here but that is an aside.

I would not use thin floating sections. Let's say the whole backing was solid in a FreeCAD design body. I would then do something like an egg shaped ellipse pocket out of the middle. Another option might be a % like shape with the thinnest section offset so that the layer lines are still substantial.

My most advance approach would be to print the face of the frame on the bed, and the rear face of the backing plate also on the bed as a second part. If designed well from the start, and if the bed is large enough, you design the print to finish the backing plate before the face is completed. Then you add a print pause, remove the backing plate, insert it into the front plate, and continue the print to encapsulate it as a single part. This makes any 2D pattern for the backplate possible, and you do not need to deal with fasteners or whatnot. You end up with a perfect picture frame slot using this method.

A total aside, but this idea can also be used to make your own printed supports manually for perfect overhangs. You print the support to size, add a pause, and remove the printed support shape. Ideally, you add a ~0.1mm-0.2mm clearance gap, paying very close attention to how your slicer layers height and first layer correspond to the support dimensions, or rotate the support to utilize better x/y dimensional accuracy if possible in some designs. You can even create a printed alignment jig on the build plate just to hold this manually created print support. The trick is to then apply gluestick to the interface between the manually printed support and your overhang. This can produce nearly first layer like print quality on an overhang with dimensional accuracy too.

Another super advanced trick: let's think if the picture frame standing vertically upright in Cartesian planes. It is facing forward on the X-Z plane (X = -><- = >< = left to right). Let's assume the origin 0,0,0 is properly centered in the frame. Now if we look at a X/Y Top, section view, we are looking at the picture frame as if someone had used a hacksaw in the middle of the sides of the frame. In other words, we are looking at the frame's profile view. Now typically, people approach this like a [. Now this takes a lot of practice, but it is possible to design a profile something like ɭ̅̅̅ ̅ ̅˻ ̅ ̷̅ – the print bed is ↓. If you design this just right, the left side is the frame and the right is designed with a small connection to the bed and an angle where this connection is close to the rest of the frame. The thin bridge overhang is going to contract and shrink towards the larger heat mass of the frame, especially because of the printed layers above the bridge. This contracting force will be set into the part like a spring, but will remain compressed due to bed adhesion. You may want to add a small first layer connection or inner skirt to hold this section in place firmly throughout the print. When the part is removed from the bed, the bridge spring will pull the right section back. This will create the slot for your picture and potentially a way of holding other types of backing, while not worrying about conforming to other types of manufacturing process constraints like a wood router or sheet metal profile.

Sorry if my lack of eloquence, verbosity, or tone come across negative at all. I wish to be encouraging and am just nerding out.

How can I ensure any videos I record on my phone aren't deleted by the cops?

I was looking for the image to see if I saved it, but apparently not. There was a image floating around of a private meeting slide presentation that showed the various phones and their vulnerabilities. IIRC, the main things were some issue with the number of allowed log in attempts when all the mobile devices are in the initial boot lock versus regular lock state. The other was how the default USB behavior is handled in the locked state. These are default locked down in Graphene. Additionally, there are tools like a second lock screen password that factory resets the device completely in the background, and automatic reboots so that the phone goes into the initial boot locked state regularly.

If they can't get into the device, they will probably just steal it.

All of this can be bypassed on most devices except Graphene OS using the tools they now have available.
