  1. Hi, how is your ssd in the mac? 

  2. The issue is if they sell ANY of their Held To Maturity (HTM) assets, they have to mark down ALL of the assets, which would likely make them insolvent. The reason why they can’t just sell them is as I said — the market value of the assets is not enough to cover the liability they cover, and the assets themselves might be illiquid (I.E. few people willing to buy that much/specific things). If they have to mark down their assets, there’s probably about a $30B hole in their balance sheet (but again, if they hold till maturity, everything is fine). Again, this is just regular boring banking, Btw, Wednesday alone they has $42B in withdrawals, out of $173B, wild. Dodd-Frank changed banking regulation significant, and has very specific rules for banks going under to prevent “moral hazard”.
  3. Generally when banks fail the FDIC just lines up another well capitalized bank to take over and assume all deposits. SVB was big but not big enough that JPM or BAC couldn't absorb them (not that they are going to/want to).
  4. FDIC is a different thing, not even included here. Think about it like this, you're a customer at a bank, you deposit $X dollars, the bank gives you a debit card, checks, supplies you a website, an app -- how do they pay for all of it? Well, the law says that they have to keep Y% as tier 1 capital, which is basically just cash, but then they are allowed to invest Z% to make money in safe assets (like US Treasuries). Let's just call X 100, and Z 60%. So they do, they buy all $60 of 10yr treasuries that pay 1.5%, they give you 0.25% interest, and use the 1.25% left over to fund their business and pay for everything. Now 2 years later interest rates rise, and 8yr treasuries pay 5% -- how much money is that $60 of treasuries worth in the market today? Probably something like $40 But they're fine right? You don't need all your money today? But what if you do? Well, they only actually have $40 in cash, and the other $60 they owe is locked up in a treasury bill for 8 more years, its there, just 8 years away.
  5. its probably just pretty boring stuff, treasuries, mortgages, etc. Seems like their issue is largely stemming from a duration gap i.e. people want money now but it's locked up for X time period, and like all regional banks they've been suffering from deposit drawdowns over the last few months as people move money to higher interest rate products. Again, pretty boring, banks go bust all the time https://www.ft.com/content/8e8084b6-a2b8-11e0-83fc-00144feabdc0
  6. Also Apple has stupidly large reorder buffers vs. other processors, which is partially why they’re so efficient—their pipelines are always highly utilized, which also helps with performance. Power efficiency wise though, x86 is (probably) never going to be able to compete with ARM—the CISC -> RISC microOp is always going to use additional power, die space, and introduce complexity into the decoding stage.
  7. Issue with superscalar processors is that it can be difficult fill all slots every cycle with instructions from a single thread (normally you can only fill ~ half), because you have dependencies between instructions etc, with SMT (or, fine grain multithreading + out of order execution) you can just fill the open slots with another threads instructions, so you get all slots every cycle. Improves IPC and utilization. Wide decoding is just expensive for variable length instruction sets (requires a lot of circuitry) so it's hard to grow the pipeline width. Also makes branch misprediction very expensive (because you have to purge ~ width * depth every mis-predict)
  8. Sounds like a high school philosophy paper and is a pretty bad take. The law should represent the will of the people, but clearly it doesn’t and instead is heavily influenced by lobbyists et al. They already do this with Germany, if you set your account location to there then they filter out all the neo-nazis.
  9. No? They’re still personally liable for the loan, same as a company. What could be a short squeeze?
  10. Little update from my post the other week. Uptime now just under 15 days. I've had some software updates installed (Adobe CC stuff, some random other stuff) and downloaded a new macOS update but not installed. Am currently at: Which is more than I was expecting (though about 3x the numbers I saw earlier), 1TB of writes is from kernel_task, which sadly obscures where the writes come from.
  11. I don't have an M1 Mac, but I do have a late-2016 MBP (the first with Touch Bar) with a 1TB SSD that I use as a daily. My current uptime is 6 days 5:23, and currently: 350GB seems like a lot of data, I don't think more than 50GB can be from stuff I've been doing specifically. So to summarize, after writing to the drive just over 75x, the drive is reporting having 100% of spare available and only having used 2% of its life (I think that's what Percent Used means? can't be storage since I have over half the drive full). It does seem like it's using a lot of writes--perhaps a bug in the new version of MacOS? But realistically, if 75x writes is 2% of life, then my drive is projected to last ~3750 TB, which at even an accelerated 125TB/yr (assuming it's not a bug), is like ~30yrs of usage. I can't imagine Apple put shit SSDs in the new laptops that have worse endurance then their old tech.
  12. Gonna lock this cause it’s obviously very out of date. Please use the COVID mega thread
  13. Oh yeah, if anyone was interested in how that Danish mask study came to a conclusion that masks don’t work, and why the study is mostly 🗑: https://fooledbyrandomnessdotcom.wordpress.com/2020/11/25/hypothesis-testing-in-the-presence-of-false-positives-the-flaws-in-the-danish-mask-study/amp/?__twitter_impression=true
  14. The discord server is currently closed, it will reopen later this week.
