  • 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


  • Not an American, but basically decide how much risk you want to take on - then depending on that answer set aside money (0-40%) for safe investments - things like bonds (guaranteed returns) or potentially gold (lower volatility). The rest goes into a 80/20 (or 60/40, or 90/10, no one can say what’s best) split between domestic and international index funds. Things like the S&P500, Dow, and US whole market index, and then some into EU, Asia/Oceana, and emerging market index funds.

    If I was the maintainer, I too would probably reject the PR because it didn’t remove the gender entirely.

    Cool, but that isn’t what happened here. The PR was closed immediately because the maintainer considered using gender neutral pronouns “personal politics” - he had ample opportunity to clarify his stance, or simply comment ‘resubmit in passive voice’, but he didn’t. Clearly the problem wasn’t the active voice, it was the summary of the change, because when that exact same PR was re-submitted much later with a commit message of ‘Fix some minor ESL grammar issues’, it was accepted with no discussion

    As an aside, I absolutely disagree with the use of passive voice. It’s more verbose, and harder for the reader to comprehend. It’s why every style guide (APA, Chicago, IEEE, etc) recommends sticking to active voice, especially in the context of ‘doing things’.

    If goes against established norms here

    What’s the established norm here. All people compiling software by source are male?

    he said politically motivated changes aren’t welcome

    What’s politically motivated about changing “he” to “they”. As you said, gender doesn’t apply here, so the neutral word is literally preferable.

    Yes, I’m sure that PR would have been accepted instead /s

    But you’re right, it doesn’t matter at all, the reasonable thing to do would have been for the guy to spend 3 seconds clicking the accept and merge button, or 6 seconds making your change. instead he wrote a comment stating that inclusive language has no place in his project
