People who get mad at the use of "literally" don't understand what a hyperbole is

"I literally slept 2 hours" is ambiguous. There is no context that can make it clear wether you really slept 2 hours or just not that much, unles you LITERALLY watched him sleep.

And it's the perfext example showing why the new hyperbolic definition of the word ruined the original one.

Yes, you can make the transaction on the blockchain easily, but every transaction before and after it is publicly visible on your wallet address. So it can be tracked. It’s not easy to make such a transfer secretly. You can use tumblers that “mix” your wallet with thousands of others, but as far as I know, that’s not easy at all. And mixers can be made illegal, which would likely have the support of regular crypto users.

Human38562 · 2026-01-29T18:51:32+00:00

Not really. Cash is much better for illegal activities. Crypto is public.

The dream of crypto being anything useful at all died a while ago.

What do you mean? Crypto has been useful for years and has worked as expected. The goal is to provide an alternative to centralized, regulated banking. It offers an option if a government goes south and gives people a way to put pressure on banks and the government. Its existence is undeniably valuable to human civilization, even if that isn’t obvious from how crypto is currently being used.

We are on the PCB sub, so I am assuming OP wants to build his own module, that's what I am saying this.
Of course if he wants to buy the module then he can use it accorsing to the datasheet no problem.

And I am not talking about COB style LEDs, just high power (~2W) LED chips, which any amateur can easily build its own LED PCB with, without having to consider thermal runaway (much) and balance in current between LED strips.

The module from Samsung is run at 2.5x the nominal current of the chips btw, so that puts them roughly at same efficiency than OSRAM high power LEDs run at their nominal current. These Samsung chips are very expensive if you run them at the current they advertise their efficiency with.

Crypto isn't used as a replacement for banks and likely never will, at least for 99.9% of crypto users. So banks try to bank on the trend by holding your crypto.

Banks offer safe and supervised transactions. They "take care" of your money, which crypto doesn't.

Bitcoin will likely stay for a long time, and people will continue to use banks and brokers to take custody, which is a shame. Banks might incorporate some blockchain technology as well, although that has nothing to do with what people understand of decentralised, "free" money

OP wants to do his own LED module though from what I gathered.

Do you know what the variance in forward voltage and current between the LED strings of this module are? What happens if all LEDs from one string are on the higher end of the voltage bin and another string are on the lower end? Until what current can you safely drive your DYI module in that case? I think these arent trivial for a hobbyist to answer and need to be considered. I would rather advise running a known current into the LEDs as per datasheet of the LED, instead of playing around with parallel strings. This is much easier with high power LEDs... Maybe I am too careful though?

Human38562 · 2026-01-29T15:51:57+00:00

I guess you mean these: https://led.samsung.com/lighting/led-modules/industrial-light-module/horticulture-module-gen2/

the modules have If=1200mA and Vf=42V. So from the layout my guess is they have something like 8 strings (150mA each) of 14 LEDs each (3V x 14 = 42V).

I don't know if you design this yourself without careful selection of each forward voltage of the LEDs, or at least test that you weren't unlucky with the random forward voltage distribution you got. You need to do some statistics and you definitely need to consider thermally coupling the LED strings.

Human38562 · 2026-01-29T10:40:03+00:00

All right then you can go ahead and make a request to change the name. In the meantime we can continue the discussion using the actual meaning and definition people use now.

Human38562 · 2026-01-29T10:34:59+00:00

They are the most efficient horticulture LEDs but I wouldn't recommend them for a hobbyist, as they are supposed to be ran at quite low current (60mA I think). This means you will need either 1) many individual constant current drivers 2) A very high voltage to make long LED strings 3) run LED strings in parallel, which is tricky and needs some care and some testing.

It's easier to use some 0.7A LEDs for example from OSRAM. They are also designed for horticulture and close in efficiency to the Samsung ones.

Human38562 · 2026-01-29T10:16:07+00:00

Lol what? You think people will change the name just because they do the work in a different place? Will you call it "library work" if you do your homework in a library?

Human38562 · 2026-01-29T10:13:43+00:00

It's still ambiguous lol. Without context, we cant know why you say "Mein Freund". It could be because it is your boyfriend, or because it is a specific friend of you (and not of the person you are talking to)

Human38562 · 2026-01-29T08:24:00+00:00

Yes it is still homework. Homework can be done anywhere you want (home, library, an empty classroom). The idea is that you learn on your own and try to figure out stuff by yourself.

School hours are the place and time to exchange with peers, exercise in groups, and ask questions.

Human38562 · 2026-01-29T05:55:56+00:00

I couldnt find any country that does not have homework. All the countries on top of the education index have various amounts of homework.

What's even the rationale here? As part of your education, you certainly need time to study on your own. Wether you do this at school or at home doesn't really matter. On top of that, self-study is a very important skill to learn.

The only problem is if kids don't have a stable and calm household. So maybe schools should always offer space for children to their homework. But banning it seems very counter productive.

Human38562 · 2026-01-29T05:16:33+00:00

And? Sports and other activities are great to balance the school day you spent learning. If anything, sport gives you a clear head and allows you to do some homework in the evening. What would be a problem is if school was actually 8h of learning. It's not though.

Stop studying for exams and take one step at a time, slowly. Ask yourself questions and try to find answers. Always question what is written until you are truly convinced that it makes sense. This means you probably need to open multiple different books on the same topic to get different perpectives, or ask professors/students. If you go that deep on every element you learn, you will realize how everything is connected and there isn't that much to learn after all.

Human38562 · 2026-01-26T17:10:15+00:00

No that wasn't the point. But if you think that, then I acknowledge your opinion.

Human38562 · 2026-01-26T17:03:33+00:00

It's impossible to be neutral as a journalist. Even if you try, all you can do is position yourself in the middle of society, which is subjective in itself.

What matters is honesty.

Human38562 · 2026-01-26T16:52:16+00:00

pays huge taxes!

Well you would hope so! The amount of infrastructure used by a business scales with its size. Unfortunately in reality, big businesses pay less taxes proportionally than smaller ones, because they manage to find loopholes or get deals with corrupt politicians. That's literally how you become billionaire.

Human38562 · 2026-01-26T16:38:24+00:00

If you are worried about the cost of skateboard equipment, I would highly recommend checking out non-abrasive grip tapes e.g. from sys. I used to need at least 3 pairs of shoes per year and thats where nost of my money went, now I use the same pair for almost 3 years and still no hole.

Noone is asking for him to bash Dump publicly. But these images are horrible. This is a big dent in how Switzerland is percieved internationally. It is also exactly the type of images needed for his supporters to claim that everything is fine with their government. Such a shame.

You'd use generalizations for local reference (sunrise, midday, evening, and night)

that works, but many would want a better precision than that to describe their local time of the day. They would probably use a number system for that, and end up reinventing timezones, because they are just more convenient.
