  • Malt is the absolute cheapest part of brewing beer, I buy 55lb bags of it for $80 CAD (so like 40-60 USD), and there are multiple shops near me I can buy from. You only need a pot, a big ass mesh bag, a carboy/airlock, and a bottle capper if you don’t have swing top bottles.

    To make 5 gallons of basic ass beer (yields like 48-54 bottles) you need 8-10lbs of grain (1lb of which is the fancy $2/lb malt; and 2lbs of which can be subbed for minute rice if you are doing an adjunct ale). You need 1, maybe 2oz of hops (hallertau is $2.50/oz). Yeast is $4-8 but is a 1 time cost because it’s reusable. To make an IPA your malt cost is 25% higher and your hop cost is like 4x

    The economics are actually great, but that’s fully contingent on you 1) placing no value on your time, and 2) not getting hooked and spending thousands on a stainless steel, PID controlled electronic brewing system, or a 4 tap home draught system (I did both)



  • Yeah I hate when I have to convert temperatures between systems, and then the nice round numbers that represent common values used in everyday life like 0, 20, 30, 40, and 100 become absolutely nonsensical values like 32, 68, 86, 104 and 212

    Metric measurements are only decimals in North America because things are fabricated to be round imperial numbers for the American market. When you buy a piece of lumber in Europe it’s cut to 45x95mm which (shockingly) converts to the absolutely nonsensical 1.77165x3.74016 inch two by four







  • Things like gradient boosting, supervised + reinforcement learning, NLP (sentiment analysis), etc have been used in algorithmic trading for decades.

    Hell, much to the chagrin of statisticians, some people even lump linear regression under the AI umbrella

    Also I think you are confusing fundamentals and technicals





  • Your computer is a bunch of parts that need software to make them work. The “operating system” handles talking to the hardware directly, while the programs you run only talk to the operating system. Talking to the operating system is easy, talking to the hardware is difficult, since you may need to speak a hundred different languages to work with every possible network card, sound card, graphics card, etc.

    The operating systems you have probably heard of are windows and macOS. Linux is a 3rd one.

    Windows is owned by Microsoft, macOS is owned by Apple, and Linux is developed by the community and (typically) released for free. Since anyone can work on Linux, there are tons of different versions of it floating around, that are all slightly different from one another.



  • 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


  • It’s Google analytics, and the meta/twitter/etc tracking pixels. Almost every site uses them because they provide useful data to the site owner and they are free.

    the images in OPs post appear to be designed to match their site theme, meaning umatrix wouldn’t even block them, because they are being served from the sites actual domain/CDN and not from Facebook/Google’s tracking domain.

    The buttons don’t do any tracking just from existing. They only exist to encourage a miniscule number of people to repost your content on social media, and in the event a share comes from that, they may include affiliate info

    All the useful information comes from the tracking scripts, which developers are also placing themselves because they are infinitely more useful. They tell you where visitors are coming from, how/if they are converting, everything they are viewing/interacting with on your site, and what the ROI of your ad spend is. In addition to telling you if someone clicked the share button.

    Tracking pixels have been decoupled from the “share” buttons for at least 10-15 years
