    The Economist reviews It Doesn't Have To Be Crazy At Work: "Their book is funny, well-written and iconoclastic and by far the best thing on management published this year" 😍🙏

    The security of the whatever fuck? The secure knowledge that putting your unsubscribe function behind a login gate leads to fewer successful attempts at unsubscribing from your marketing emails? Guess I shouldn’t have expected better by a Facebook-owned company.

    I gotta say that the MBP16 + an iPad for an extra screen does a passable impression of the experience you get from the 27" iMac. Not quite there, but not that far off either.

    This video is remarkable, asked about US a greenhouse gas emissions compared to China, Michael Bloomberg goes into a full throated defence of the regime in Beijing on the environment, on their lack of democracy. I can’t believe how bad this is.

    I dream of a world where every company is as keen on giving customer service as they are on measuring it.

    Some days Twitter is like a time machine. Transporting us back into 2005, when Serious People had Serious Concerns about whether you could be “successful” with Ruby on Rails. The next decade obliterated those concerns, but the past is not always distributed evenly 😂

    “Seeing these posts that definitively invalidate my bizarro preconception that you can’t be successful with Ruby is so strange! It’s almost as I’m categorically and hilariously wrong, but that’s clearly impossible, so it’s really very strange. So strange!” 😂

    Replying to @honestduane @dhh
    I would love to see real success with ruby, but I have never personally seen a company be successful with it from the start. C#, Python, Go, F#, C, C++, Rust, Java, etc. sure, but never Ruby. So seeing these posts is odd because your evangelizing something I have seen only fail.

    New York Times poll finds that a wealth tax is popular among Democrats, Republicans and independents — and among every education sub-group with one exception: GOP men with degrees.

    ❤️. I should start my own thread of "as I got older" refuting all the bad takes I used to spout. Although, I don't think it's really aging that does it. It's having more time to learn, to listen, to experience the life and perspectives of others. Plenty of old people missed that.

    Replying to @dhh @jkup
    I used to be in the "Rails is slow OOTB" camp but as I got older, it's more about how you architect things. Rails works out really well for building out the product and when the time comes, you can break critical off into their own services that Rails can still talk to.

    To the larger point: Nobody thinks less of the needs, desires, motivations, and humanity of programmers than their fellow programmers. Far too many programmers have more sympathy with the machine than they do their fellow humans. SAD!

    How about some nerd stats for with ? 128,000 Unicorn workers served 90m unique sessions at a steady 17M RPM (requests/min) throughout the day. Over 1b webhooks sent, transformed 280m webp images at the edge and 34b requests to CDNs. 74m Flows ran.

    When I look at our, comparably small, bill of hosting at Basecamp, the majority of that is spent storing files, running analytics, database servers, redid cache servers, and network gear. A very small minority is CPU power for Ruby processes!

    I'd wager than in the vast majority of internet-business domains, the all-in costs of programmers far outstrip the sums spent on the machines dedicated to CPU runtime of a given programming language. And even if it's close, you should side with team human.

    That's even accepting the false premise that you'd actually save any money moving happy programmers from an environment like Ruby to something that optimizes more for the computer than the human, because computers are expensive!

    Letting your programmers use the most beautiful, motivating, productive, and delightful programming environment you can afford is a tribute to their humanity. Forcing them to step down, not because you must, but because the bottomline might see a few $ is just worker abuse.

    The peanut gallery response to this is hilarious: BUT YOU COULD HAVE SAVED A LITTLE BIT MORE MONEY IF YOU MADE YOUR PROGRAMMERS SUFFER UNDER ANOTHER LANGUAGE THAN RUBY?? Did your shareholders think about that?? Also, $1.5m per minute is, like, not THAT much, you know???
