    At we analyze funnel/cart/checkout data to attach a $ value to every bug (crash or otherwise), so you can work on what actually matters. Btw, I'm looking for expert iOS devs to join us, DM if you're interested!

    I've seen teams of iOS devs at huge companies get derailed by CoreData bugs. These bugs have had a revenue impact in the *millions*. Helping them track down these CoreData problems is not fun.

    Finally, CoreData is overkill for most apps. With in 2012, I found just writing .json is easier/faster and you don't run into threading issues or mysterious CoreData crashes!

    Oh wow, Apple finally suggests to write files to disk instead of using CoreData for everything.

    My battery's early failure seems to be because I always leave it plugged in (and use an external monitor). Someone wrote some software to control the max charge level, discussion here:

    My 2018 MacBook Pro has an expanding/swelling battery, after only 375 cycles. says it'll be a $400 fix to replace the "top case", says computer unsafe for use. Anyone else seen their batteries fail after such few cycles?

    I was in Kyiv through Ukraine’s revolution, don’t remember any shop getting looted. And the revolution was successful.

    On iOS 13 with checkra1n, do I have to do something special to use mmap with PROT_EXEC? Already tried the dynamic-codesigning entitlement.

    It seems it's called "Озонотерапия" and there's at least one place in Kyiv that offers it, wouldn't hurt to try with willing patients and discover the truth.

    In Ukraine, where rates are high, housing is reasonably affordable for savers. As rates drop, housing will skyrocket, despite general productivity being basically the same. Not good for people needing housing (the same way college became unaffordable because of low rates in US)

    Low rates have led to high housing costs and general “lifestyle inflation” (people buying i.e. cars they couldn’t otherwise), and discouraged saving. High housing costs impacts spending on everything else. Would love to see an alternate world with free-market interest rates.

    Been thinking a lot about interest rates recently, I can’t help but feel my generation will have to deal with the long-term consequences of low rates.

    As I get older, I feel like at most points in my life I have underappreciated how large the impact of prevailing interest rates were on things which I cared about and probably underinvested brain cycles in understanding the same. Perhaps that is a life lesson for some people.

    In previous jailbreaks, you could attach to any process with the Xcode debugger, resigned or not. This doesn't seem to be the case with , any workaround available? /cc

    that KVO's valueForKeyPath: supports collection operators, you can do stuff like max, avg, even distinctUnionOfObjects. Works with paths as well, ie .owner.creationDate

    The view debugger isn't particularly helpful for SwiftUI (showing Text as a CGDrawingView), but it is telling that it's still UIView/CALayer backed. I'm sure in the future we'll see those underlaying layers swapped out for something Metal/Swift powered.
