  • We’re at a point where it’s no longer profitable for individual miners

    We have been at that point since GPU mining stopped being feasible in 2014, it’s just gotten worse. ASICs made it so the only people who could profit off mining were people who could place a wholesale sized order of hardware from bitmain, etc. Anyone else who claimed to be mining profitably was likely someone who was:

    1. buying old hardware 2nd hand (or new hardware at MSRP) and capitalizing on free electricity in their rental
    2. not selling their Bitcoin immediately (they weren’t making money from mining, they were making it from speculating)
    3. lived in Quebec and could double dip (North America’s cheapest grid + free heating for 8 months of the year)

    unless there’s a radical change in bitcoin’s algorithm

    The algorithm already does this though. Every 2016 blocks if it took more than 10 minutes per block, the difficulty of mining bitcoin goes down, not up. This is why every halving event you see a radical drop in difficulty, because at a given kWh you are producing half as many bitcoin - meaning people turned off their miners because it’s less profitable. The flipside is the rate of issuance goes down, so there is a lower inflationary effect, and the price of Bitcoin usually also skyrockets (which means eventually these miners re-enter, and difficulty eventually goes back to where it was). It can never get to a point where Bitcoin mining is completely unprofitable unless the price goes to zero, because there will always be a guy with a solar panel and fully paid-off hardware who can mine it for free. Granted, it can get to a point where a lot of people have to take a huge loss on capital expenditures if the price nosedives and never recovers




  • New data tells us that mining a single Bitcoin or one BTC costs the largest public mining companies over $82,000 USD, which is nearly double the figure it did the previous quarter. Estimates for smaller organisations say you need to spend about $137,000 to get that single BTC in return. BTC is currently only valued at $94,703 USD, which seems to be a problem in the math department.

    Bitcoin mining will always be profitable for the people with the cheapest electricity and largest economies of scale. There is a difficulty adjustment algorithm in the protocol that ensures this. When the price tanks people turn off thier miners, difficulty adjusts downwards, and then it takes less electricity to find a block.

    tl;dr title is wrong


  • Yes, it was hyperbole, but saying “CodeWeavers does contribute back” is really downplaying it, many, if not most of the wine development is done by CodeWeavers employees (including Alexandre Julliard). Mac users buying crossover was pretty much the main economic driver turning the gears of wine for the 10-15 years before Valve started sponsoring it as well.

    still can’t trust them long term because profit

    The company is an employee owned trust (co-op) if that lessens the blow



  • It absolutely improves with practice, and once you have settled on an aesthetic you like you can simply reuse the code, e.g. store all your color/line properties in a variable and just update each figure with that variable

    My thesis had something like 30 figures, and at multiple points I had to do things like “put these all on a log scale instead” or “whoops, data on row 143,827 looks like it was transcribed wrong, need to fix it”

    While setting everything up in ggplot took a couple hours, making those changes to 30 figures in ggplot took seconds, whereas it would have taken a monumental amount of time to do manually in excel







  • Like once a month we have a fake site pop up using the name of our business with 1-2 characters changed. They use a web crawler to scrape all the content off our domain and they re-host all of our products on a woocommerce site where they steal our customers credit card information.

    These all use cloudflare to conceal the hosting providers, who are entirely non-responsive without a police report or WIPO ruling. When all is said and done, the content is being hosted in China, Russia, or South Africa, meaning the only way to remove the content is from the registrar’s, because they are the only link in the chain that actually has to comply

    Ok, not in the US so idk. the last CFL bulb I bought was long before 2009.

    Either way, the brain still uses more power than a 13W CFL, and the tumblr post is from 2018, and the Reddit post is even more recent. “It would have been technically correct if it was posted 20 years ago” doesn’t really change the fact that it’s not true anymore
