I'd maybe pay to have all IR junk and screen side camera removed. I'd definitely feel it adds value if they would clamp the speaker and mic to the audible range with a hardware filter. Give me a hardware switch to remove modem power and I'd be happy.

Just flash a ROM with a programmer or more?

It was a gift. It might get homebrew if I get motivated enough to look into it

No one wants to swim next to a drowning person with their head deep below the surface of democracy, hitched to the wagon of a fascist. That garbage is just hype, or the duty of every American to fight.

At some point some kids learned they could get food and shelter by peddling the dumb shit their dad made up when they were kids.

"Daddy, where is uncle Larry after he touched little Susie?"

He's burning in hell sweetie.

"... Are we having bacon tonight daddy?"

No sweetie. That's uncle Larry in hell.

I see your nuance better now. I'm saying that diversity is not a qualifier for total artistic value. I believe it is okay to tell flawed stories as art. I do not believe that all stories should be flawed, they should be an exception not the rule.

This is where we are likely strongly aligned versus any potential for difference. I believe telling better stories is the failure of the entertainment industry. There are plenty of better stories to tell. The real prejudice is happening by the cowardice of choosing misogynistic stories to tell. Really, there is not enough value placed on the big picture abstract overview. People are playing with the trees when they should be managing the forest. Old familiar stories with foundations built in an era of a lack of diversity are ripe to abandon for a new era of better stories.

In the last 10 years it has become common for devs to disable and remove or encrypt to prevent reverse engineering and repairs. If the device is older, the debug info from UART is likely still present. How useful that information is may be dubious.

Most of what you are saying about functionality is not in line with how a microcontroller works. The microcontroller is not sophisticated like a real computer. It is like a very simple state machine running on the device. Basically it is like a single long script that is not running on any kind of abstraction layer. When the device is turned on, there is the script. The script is not executed by some operating system or any other complication. The entire software stack is the script. Only, the script is actual hardware registers and flags and operation codes.

There is a tiny amount of RAM that actually runs the script, like 16kb. There is the programmed memory, like 32kb. Then there is a tiny amount of electrically erasable and reprogrammable memory, like 4kb. The eeprom is the only section of memory that a microcontroller can access to write persistent data, meaning something that will still be present when power is cycled.

I doubt many people use eeprom to save any kind of error. This is more like where a serial number might be saved, or more likely the calibration values for some internal control algorithm. It is not anywhere near large enough to save something significant like the script.

It is far more likely that the script is just a state machine and is reaching an error state because of some missing or bad signal that it needs to continue running the script. This is likely your problem and the issue is like 99% likely to be hardware and not the microcontroller.

Resetting such a device is just an interrupt signal that restarts the script. There is nothing dynamic about this.

From the perspective of the original dev, the ISP programming interface has the functionality of brute forcing running code to step through each machine instruction and halt further execution while monitoring or changing any value present in any register of the internal microprocessor. This is super powerful but requires a pricy setup from the manufacturer in most cases, and a thorough understanding of the internals of a microprocessor's registers, op codes, memory addressing, interrupts, clocks, and the ALU (arithmetic logic unit).

In this type of device, text strings are far too expensive to have much, if any, value. Any such debug info is likely to be very terse. Text strings take an enormous amount of memory space to encode, so in general, these are not used very much. A microcontroller is a far simpler device than this. It is a computer in the sense of a device that can do Input/Outputs and run a control algorithm like a temperature controller with a PID loop.

There are a half dozen or so people that cause 90% of all negative behavior according to an admin on another instance. LW does not seem to take responsibility and act to stop these 0.0001% of bad users.

Mods can't see jack ****. Only admin see that info.

Unfortunately LW doesn't take updating the Lemmy version seriously either. The server version is WAY behind and the very next version of Lemmy adds the ability to turn off all negative votes at the user level. That single feature would likely improve the mental health of most LW users substantially.

There seems to be a similar general demographic of late 30's to early 40's users here... (could easily be my confirmation bias saying that). I was around for Napster, GeoCities, MySpace, Yahoo, Mama, AoL, AiM, and if you are ~40yo, you likely were in this same wave of broad scale adoption of the internet by average Joe jr public in the latest 90's and early naughties. We are the first group where digital life is the rule, not the exception(s) and early adopters; the first gen of internet grandparents... How does that legacy play out. /r

 

I've messed with this dozens of times with various AI models that are generally good at abstractions with advanced prompting, custom diffusion settings outside of the typical, and some hacks in the model loader code. I seem to lack the vocabulary to describe the fundamental geometry of centrifugal gravity in the kind of depth required. Like how does one say that the road ahead curves up like a hill continuing overhead with the buildings anchored to...

I need language here that has unambiguous specificity and likely does not occur in any other context. Layperson verbosity will fail to get traction without fine tuning the model first. I prefer to explore what models can really do using settings and the prompts only.

Most of my vocabulary and understanding of geometry is limited to the Cartesian planes and CAD assemblies. Perhaps someone here has a better lexicon and doesn't mind sharing.

What was it like for someone that was:

  • not associated with anyone related to those persecuted by Nazis
  • generally apolitical
  • a homebody type that minds their own business, while feeling powerless and largely apathetic to a less than ideal government

Let's say they were unemployed since November of 1929 going into 1930 with a family, 2.1 kids, and a house, with a BA in basket weaving or something otherwise mostly useless that checks the boxes for middle management. What was life like before the Russian Bear got woke for those 12 years before and during the Nazis?

Why do prisons exist? (self.asklemmy)
submitted 1 week ago by j4k3 to c/asklemmy
 

This is not a question of about parroted nonsense and cultural norms. I mean what end product do they produce that justifies their existence in the first place.

I'm physically disabled and have been living in a prison like situation for nearly 11 years. How does my situation balance into the ethics of prisons? I'm on a path to homelessness and a premature death due to institutionalized neglect and abuse from US institutions. Criminals are housed and fed in exchange for similar isolation, abuse, danger, insurmountable debt, and a largely unemployable and destitute future. These seem to conflict in ethics.

 

Already did my usual 16 mile physical therapy routine, so I did it again. Haven't gone over 26 miles in ~3 years. Me and the cats, dead in a bed rn, 2 brain cells between the three of us

 

Like all buildings should have some kind of standard for solar panel placement added or retrofitted with a very low cost modular mounted frame. Then, when you get an appliance it has a built in battery and comes paired with the right size panels that are sized for each region in the local store/wholesale distribution layer.

The whole scheme is hybrid in the first phase of a decade or so while edge cases and issues come up, like how to handle high rise buildings. Then the burden of grid infrastructure is less of a burden on the poor in total because few people are going to replace all appliances in this instance unlike those that can install a whole house solar system. The entire thing would be more incremental and serviceable over time with modularity. It is less efficient overall compared to a single controller and battery but doesn't require large upfront cost or repurchase later down the line.

 

I get the stupid basic excuse about big tech purchasing loads of silicon. That reasoning seems deeply flawed and idiotic to me. If Deepseek R1 democratizes training more for less, then that means customers with mid to small size data centers like universities now have access to train and research models in this space. Nvidia does not have a real competitor, so they get the sale. Their potential customer base just grew exponentially right? OpenAI should be devalued massively by this change, but I don't see why anything impacts Nvidia negatively in this instance. Am I missing something or is the market this level of stupid? (I have no skin in this game)

 

I'm especially interested in the disabled or people that have to rely on others for support, government or otherwise. Tell me your story if you are up for it. I don't care how old this post is, tell me anyways.

IIRC that NTE chip is a classic LM386 amp. This was one of my first electronics projects. Other than the chip and a few passives, it is all junk. I was building a center divider so that a small cord could be kept in the other half of the case and to mount the battery holder, switch, and barrel jack for using a DC wall wart instead of batteries, but never got that far.
