KleerKut··on We have lost access to approximately €6k in bounties
I'm a different person than above, I have brain damage, and I got all of the information I posted from the article. I get it that some crypto company bought Bounty Source. But in the article they said, "bounties were handled by Team NewPipe. I had set up the account for Team NewPipe on Bountysource, which accumulated a significant sum of money over the years."

I understand that they have a lot of volunteers and it isn't easy to get a consensus. Maybe they should have thought of that first? Or perhaps just make a decision and let it be known it would be happening in X period of time that unless there was significant outrage that they were going to do X? Even if they were never going to cash out of the deal, they could have used it to pay other bounties to get work done. Or sit on all that money until it evaporates.

"but we did not want to get paid for working on a passion project" If they didn't want the cash in the first place they could have put it towards something else open source. Plus they are complaining about not getting paid while saying they didn't want to get paid. This would scare away anyone wanting to help if they are going to go about things this way, but I don't know because apparently I didn't read the article.

Why did they even set up a bounty source if they didn't have any plan for spending the money, dividing it, or using it to pay someone who wasn't passionate for the project? They would have been better off spending the money on people not passionate about their project, or perhaps paid bounties to other projects. Now the money is gone. I'd definitely call that leaving it on the table.
KleerKut··on Charging a lithium battery to 80% only?
Are those cells 4.4v? Samsung makes great cells, and if you only charge them to 4.2V or less they should last quite a while. When charging to 100% means different things in different cases for the same battery technology then things get murky.
KleerKut··on American drivers have a blinding headlight problem
A local business had installed some expensive LED lights and were having flickering issues. At the time I remembered seeing something about power supply design and how having no resistive load on the circuit would cause issues with the power supplies. I had them replace one bulb on one string of lights with an incandescent and they stopped flickering. Another one for the circuit on the other side of the room and the LED flickering was gone. The fluorescent bulb flicker was an entirely different issue, but they weren't nearly as obvious from a distance as the LEDs were.

I too strongly dislike the lack of replaceable bulbs in newer LED fixtures. It's outrageous how many things in modern construction shave a few cents here and there to get the initial cost down, and the long term costs are enormous. Once the house is sold it's someone else's problem and that mentality is disgusting.

KleerKut··on RadTrike Electric Tricycle
I have mobility issues, and the chances of me dying on the road are amazingly larger than that of a pedestrian dying from me on my bike, no matter how reckless I could possibly be riding. If I have the choice between becoming roadkill or getting harassed by police, I will always choose the latter. It should be the job of the rider to yield to pedestrians the way cars must yield. If a rider isn't paying attention or going too fast for the situation, they are going to get hurt regardless of there being a pedestrian or any other obstacle. There is no danger to the motorist's safety when they mow down a cyclist. Source: I got mowed down by a police officer who buried his head in his laptop and slammed on the gas at the same time, veering uncontrollably. Luckily he wasn't injured. He had no clue he hit me until my bike was completely under his car. Somehow I managed to stay on his bumper and not go under.

This type of thinking, "One person might be frightened, so let's continue to make cyclists pay with their lives" is unfathomable. It's even more incomprehensible that it seems to come mostly from motorists wanting to dictate how all pedestrians 'shall obey' because the are second class citizens. "One could argue" all kinds of things without data and get nonsensical laws passed that affect other people and not themselves.

Furthermore, sidewalks already exist in vastly larger coverage of most cities, where bike lanes do not. Most places don't want to pay for bike lanes, and those that do rarely maintain them in the US. They have never run a street sweeper over the bike lanes where I live, and if they had, they would have hit the concrete spill that's been there for over 3 years and likely damage the street sweeper. It's outrageously dangerous if you don't know it is there because it is between the roadway and a turning lane, so if you get ejected in either direction you are possibly roadkill either way.

I don't understand why people don't fight this silly rule about bikes on sidewalks. The number of people being maimed and killed by cars while on bikes is substantially higher than the number of people being maimed or killed by bikes while walking. The difference in speed and mass is orders of magnitude smaller for a bike. Yes, there will always be those clowns like you see on YouTube with bikes going much faster than is safe or sensible, and those people deserve to be punished for their recklessness.

I'm even all for having no limit on watts or horsepower. If I want to haul a heavy trailer with a custom bike that draws 10kW but can't break 20 MPH, I should be allowed to do so. Having the torque to quickly get through an intersection saves lives and impatient drivers are less likely to make dangerous maneuvers if people can get out of their way quickly. Cars don't have HP limits, they have speed limits, and those same clowns who risk themselves and everyone around them for fun are always going to do what they want regardless. I feel it would be better to make speed limit laws stronger and get rid of the laws that pit pedestrians against other pedestrians over antiquated statutes.

KleerKut··on New concentrator could help solar panels capture more sunlight without tracking
https://en.wikipedia.org/wiki/Solar_cell#Disposal

Concentrators are actively trying to put more of the suns energy (an thus UV degradation) on the cells than can be achieved by simply aiming the cell at the sun. It greatly depends on the type of cell being used, with many technologies having a shorter lifespan than polycrystalline and monocrystalline cells, but they don't last forever out in the sun. A panel boxed up in a warehouse isn't likely to have discernible cell degradation in 10 years. A panel flat on a roof having off-axis light will degrade more, one on a solar tracker will degrade more still, with the benefit of more power per unit time during that shortened lifespan. Add in concentrators and it will degrade more still. Much like anything else. I'm getting no sun indoors, get more standing in my yard, get even more standing near water where it reflects back at me and get sunburn (degradation) quicker in that environment.

Obviously it makes sense to aim the panels at the sun, and having a method to seasonally adjust the tilt can be done for very cheap. It can be made to last the life of the panels without repair, and it isn't an outrageous loss of performance if it was forgotten for a few weeks. Active sun trackers can potentially cost more than the panel itself, even more so when factoring in installation and setup. If it fails aiming to one extreme, there will be a substantial loss in power even compared to a panel with a fixed mount. That failure is likely to happen more than a couple times in the life of the panel, unless you replace parts before failure (even more cost), or add concentrators (more cost) to increase output and decrease panel life (more cost yet again). Unless there is a specific reason for all of that cost and complexity, such as space constraints or other factors, then it is cheaper to just lay out more panels. If a new technology comes out where they can stop UV degradation without a large impact on power output, or weight, or cost, then I'll be interested. For my use case I'd rather reduce my energy usage and lay panels in the sun with seasonal cleaning and adjustment.

KleerKut··on New concentrator could help solar panels capture more sunlight without tracking
Agreed. Unless you have serious space constraints, more cheap panels which last decades is far cheaper and less maintenance than any solar concentrators or solar tracking that will fail long before the panels. I could see those technologies being useful on a trailer for generating power in remote locations, but not for the typical home or solar farm. I'd imagine those lenses would amplify the shading caused by typical dirt and debris, requiring more labor costs.

The other thing is that solar concentrators burn the cells out quicker, it isn't magic free energy. Spending a significant amount more money just to squeeze out more power from the cells doesn't make sense for all applications.

KleerKut··on Ask HN: Favourite open source game?
SuperTuxKart has come a long way and is very well done. I haven't tried the online multiplayer, but it looks pretty good. I was really impressed that my Driving Force Pro racing wheel worked out of the box. Now I just need to fix the pedals which were designed rather poorly. Fortunately they can be improved with a couple of new potentiometers and some spring steel.
KleerKut··on Millions of electric cars are coming. What happens to all the dead batteries?
The lack of ideas working towards reducing and reusing before recycling is deeply disturbing to me. My understanding is that many people and companies will consider a battery dead at a point where it still has a great deal of life left for other uses. There are plenty of places selling gently used, or even completely unused batteries at deep discount, which is great for solar and smaller vehicles like bikes. The weight isn't much of a concern for stationary solar beyond initial shipping, and a few extra pounds on a bike to get the same range for much cheaper than new has served me well. I would love to see shops pop up reusing batteries for bikes, golf carts, and more. I'm happy to see many gas powered bikes and golf carts in my area being replaced with electric.

Calling for legislation to recycle batteries without regard to the order of the 3 R's seems quite wasteful and likely to inhibit innovation with small scale solar and smaller electric transportation. Reduce, reuse, then recycle seems like a better idea than skipping the first two steps.

KleerKut··on Off-Grid Cyberdeck with RPI and Pelican Case
Harbor Freight has nearly identical cases to the Pelican that are a lot cheaper. I recently used one mounted on the front of a bike that I converted to electric, with the battery and motor controller jammed inside. They occasionally go on sale, and I wiped out their inventory the last two times I went as they don't seem to carry a lot at once. Hopefully I'll get around to making a cyberdeck out of one.
