Whatever it is. You're interested in if you're interested in gardening. How do you monetize if you're interested in making in sports. How do you monetize that. If you if you're interested in comedy podcasting or writing or or finance how do you monetize it. It's not so easy. And so. I wanted to write a book that covered both lanes as opposed to one or the other one hundred percent. James listen oftentimes fire nation.

Does anybody get good at something doing it once a week or four times a month like i gonna put in the wraps. I'm a bad interviewer. A bad podcast host right now. I've never done it before.

Medical Billing with Sarah Kliff

"Today. We're talking about medical billing and to start. I sat down with sarah cliff. She's a reporter at the new york times and like me. She actually enjoys talking about the stuff in healthcare that most people find kind of boring. I love policy. I find it super interesting. I find risk adjustment. And all those little wonky actually. Is you know david matter a lot. And the reason. I think i find it so interesting is not you. I like reading long documents. Probably more than the average person. But i really find it interesting because all this policy affects people. Sarah said that even though she focuses on patient bills some of the most damning stories are the ones that don't have paper trails like one mother who contacted or recently to share. What happened when her two year. Old daughter got into her purse and took a bunch of dramamine tablets. Very interested in putting anything they can in their mouth and She wasn't sure how many drumming tells there to begin with or how many her daughter eight chicago's poison control and poison control. Says she's probably fine but we think you should take her to the emergency room because there is a risk of seizure if she does dreaming overdose. This mom turns out to have already twelve hundred dollars in medical debt from an emergency room. Visit a few months prior and the mom is thinking. I don't i need mammal the pay that bill. I don't have the money to go to the emergency room. I don't know how much the cost i know. It's going to be expensive. So what she does is her husband again in the car and they decide they're going to sit in the parking lot outside the emergency room and if their daughter starts having a seizure they're going to run in and get treated but if not they're just going to sit there and monitor her kind of within. You know sprinting. Distance in the emergency room door so their daughter watches the little mermaid. They sit there for a few hours. Nothing happens and she goes home. And i think it just speaks to like the way americans interact with the healthcare system where you have cases where parents are being told you should bring your child to the healthcare system for monitoring and patients are just too scared of the billing implications

Second, I could start to read bits out, so let me run back here and run over this attack scenario. Again, we understand it a little bit there is you basically tack works because I can set the non architect at St. on just winning wall instructions in the normal way, being uninterested in result except aside effective hacking the the, the none architecture state. So flush my own cash and training the branch buffer so that the Ray links check passes normally which only will then load into the Ellen cash. The secret key. I want by act by trying to use it in one way and having my test bite, my fake password fail. The the real key is in cash. Now, did I run the attack? There's a first load of the array links. It's slow. It misses in cash and now have the shadow of the Kashmiris to go do some other work. There's a comparing check, which are all speckling because the loads unavailable, I then load the the index value, which I picked to be within your AM. I'm rain, checking, get a pick to be the KEA wanna get. So I load into some, you know, registering inspector register. It totally roll back when the ranch fails, but I don't care. So some specter of register holds the secret key bite. It get scaled and then a second load modifies signals. The third load modifies the state of Owen cash by a by loading a cache line that's scaled by the secret key. I want any tax basically over the Ellen cash holds the one of the two hundred fifty six combos of key catch lines have been modified b. loaded and though to five. We're not loaded and there's some other junk into cash care about, and I go now to my cash looking for the fast one line.

"That's all Ray because you need to. So you're he's well past that he's far off the end vizo speculative mind you and he loads into some register, the secret value that I wanna get. Okay. You listen to a special register, it's not party architectured state yet. So the tanker me can't actually read it, but then the value that got loaded speckled register gets scaled by an amount larger than the size of your cash to be six as some scaling happens all time. And then this used for a second Raillard. And the second reload then is the second different buffer, but now has this giant value that's offset has the key by looking for scale by something beer than a cache line. And so I don't care if it lands in the second buffer or not, because all looking for a change in the catch. So there are three loads in Roker a load of Ray. Links that's missing cash. That's pending a load of the crypto key, which his it has to be fast because this work has to happen in the speculative shadow were waiting on the load from main memory for the come back. So we have to quick but didn't cash because I did a crypto load earlier. So it goes on a couple of clocks done. It got scaled and then we load a third time off scaled amount. So now on the address side of the cash, I had the seek akiem looking for scale by a larger month to be sex, some random buffer care what, and I don't care loaded on the loads of cash. I just need the secret key scaled in the address the catch. And now tax basically, Don, I'll do a timing attack, Reebok k. I go to my own cash. I try all two hundred fifty six combinations for the byte, just secretly loaded and I just load them in time each load. And for the one that's already loaded, it will be. Fast. Another two hundred fifty five or none the cash flow..

So the architect, it harbor state as thing that compile the harbor guys guaranteed the software writers about the hardware here. Registers on Intel, went from eight to sixteen some years ago. One is the stack pointer and you can't really do Elsa that roughly fifteen registers. There's a set of instructions that do things like load for memory or stored in memory or add compare jump ranch or whatever. So there's a set of instructions and registers that taken together to behaviors of those together, defined architect state with. They don't specify in that architecture. State is the performance of any of the stuff and to make it go faster harbor guys, added villain architect state that's not visible to the suffer riders directly, but it's useful in helping the processor run structure faster on. So what is non architect?.
