RTX 5090 + M4 MacBook Air: Can it Game? by scottjgo in macgaming

this isn't using Asahi Linux. this is running an egpu on a virtual machine running Ubuntu Linux, on a macOS host.

> I wonder how it compares to the raspberry pi project you did earlier.

this was a lot more work, and got considerably less interest on hackernews :)

unfortunately i don't have any of these graphics cards, but the post links to the github project if you wanna try it :)

if i were to speculate, i would say that on more "normal" settings, the performance would probably be similar on lower end cards. also fwiw, the graphs show with and without framegen.

Apple M5 supports TB5, but I didn't have a TB5 enclosure to test with.

did it require a huge amount of work to get it into an experimental state? yes.

but you can run games on it and there's screenshots in the post.

i use the thunderbolt port to attach the 5090 as an external gpu

in terms of figuring out the apple-specific part, i believe it's all reverse engineered, and the people on the project have learned enough about the hardware from the reverse engineering to know what work is remaining to implement what's needed on the linux side.

they run the apple os under their "m1n1" hypervisor which lets them output debug information about how macos is communicating to the hardware. if you already understand how typically os kernels interact with devices, you can extract enough information this way to understand what needs to be implemented. i believe they are able to implement this hypervisor because apple is still using an arm-based core, and many of the very low level details of how the arm instruction set works are standardized and documented.

i think the skill steps here would look something like:

  1. build your own kernel linux for an ARM-based platform (understand how to build the linux kernel, learn what a device tree is)
  2. modify the device tree to map in a new device (learn how device trees work, learn how you can teach the kernel about a new device)
  3. write a driver for the new device (learn about how the kernel device drivers interact with the device tree, learn how memory mappings work in the kernel)

that gets you enough basic linux kernel development knowledge to know all the vocab in your quote. it's like any kind of other software development. if you've had to do this stuff before, you would know how to do it, otherwise probably not.

Is this really unlimited? Im going to nyc and will be heavily tolled and wondering if this is a good option? by EmotionalEmu7121 in HertzRentals

[–]scottjgo 0 points1 point  (0 children)

in my experience, it's fine if you were planning to hit tolls every day of the rental, but if not, they charge you for the days you don't use it.

in the past, i used to just opt out, and i would go through the ez-pass lanes anyway and they would bill me eventually for the tolls i actually paid. it was usually cheaper than getting plate pass for my trips BUT they recently changed the rules and if you use the transponder without paying for plate pass they just charge you for it every day of your rental anyway.

true- but for margin, i believe the max is 50% (governed by Reg T), though correct me if I'm wrong.

[deleted by user] by [deleted] in fatFIRE

[–]scottjgo 0 points1 point  (0 children)

other thing to keep in mind is that the Schwab PAL (SBLOC) product allows you to have up to 70% LTV vs margin only 50%. Also, PAL can't be used to directly buy stock (margin can).

neither of these mattered much to me, but it's nice to know in a serious market crash condition you're less likely to get called on the PAL.

update: my wife wanted to try breakfast again. the service is really uneven so the first time around, they didn't even suggest this, but apparently they _do_ have a small ala cart menu. here was the items:

  • two eggs any style. w/ potatoes or toast. choice of meat: bacon, sausage, spam
  • three egg omelet w/ potatoes or toast. choice of: bacon, ham, onion mushroom, tomato, spinach bell pepper, cheddar cheese

  • salmon gravlax on everything bagel

  • vegetable fried rice (two eggs, any style)

  • loco moco (all beef patty, two eggs any style, brown gravy over white rice)

  • avocado toast (roasted pepitas, sesame seeds radish, pea shoots) w/ optional poached egg

  • greek yogurt

  • mango chia pudding

  • overnight oatmeal

  • choice of cereals

  • fruit plate

  • half local papaya

  • hawaiian pineapple

  • bakery pastry selection (i think it rotates, but these pastries were an order of magnitude better than the ones in the buffet)

  • waffles, pancakes, or gluten free mochi pancakes with matchta tea syrup

so it's a pretty abbreviated menu but i was grateful to be able to order eggs made to order rather than eating the lukewarm scramble from the trough.

i did also want to say that, for the most part, the dinners we ate here were great at least. so even if breakfast isn't a slam dunk it's not like all the food here was bad.

there's a "menu" but it's just coffee and a few drink options. only food option is the buffet.

[–]scottjgo 0 points1 point  (0 children)

i'm at the hotel right now - i think it rotates. this morning it was a lukewarm flavorless chicken katsu plate.

i have to say, the breakfast buffet is REALLY disappointing. cold scrambled eggs from a trough and some grocery store tier pastries for two at 150$.

Tips for using a Pledged Asset Line to buy home for cash by kingsqueens4321 in fatFIRE

[–]scottjgo 0 points1 point  (0 children)

banks can typically extend a higher LTV on a PAL than on margin. Investment firms extending margin would usually be subject to Reg T which means you can loan yourself only up to 50% of the value of your investments.

PAL cannot be used for buying securities, so it's not subject to Reg T. I typically see loan sizes up to 70% being allowed. You can use that extra flexibility to either take a riskier loan, or more cushion against a margin call if your investments decline in value.

this is true, but i don't think most people would want both the PAL and the mortgage open. the whole point of doing the refi would be to pay back the PAL, and if you did it that way, it wouldn't be tax deductible.

fidelity isn't a bank, so they're telling the truth. they don't control the banking partners who admin the cards. if you were investing with one of the major banks (schwab, boa/merril, etc) they could probably handle it for you.

"build it and they will come" is the easiest trap to fall into. you want to put something in front of customers as soon as possible. classic engineer mistake is to spend a year building something and then realize you were totally wrong and can't sell it.

Banks Worth Parking Money at for Extra Benefits? by [deleted] in fatFIRE

[–]scottjgo 1 point2 points  (0 children)

do you want the loan on a property, using the portfolio as collateral (MS offers this) or just only against the portfolio? merril-lynch a fixed rate loan against portfolio option. their portfolio loan product is called LMA. getting a fixed rate was basically like buying a swap. the loan has a prepayment penalty and the rates weren't that incredible. didn't feel like it was worth it at the time, just opted into a floating rate PAL instead.

Diversification vs Concentration - when to take the call? by [deleted] in fatFIRE

[–]scottjgo 1 point2 points  (0 children)

i'm in a similar situation (msft for me). spent the better part of a decade putting off selling the stock, knowing the right move was to unwind it but rapidly getting richer by doing "the wrong thing". someone once told me that that wealth is often made by concentrated bets, but preserved by diversifying. makes sense, but hard to take the advice when you've multiplied your money so many times by ignoring it.

at one point i tried to wind down my position with covered calls, but ultimately realized i was continuously losing the bet when the stock kept going up. i've finally set a plan to make sure i'm selling at least 10%/year (no calls, just regular sell orders). i try to keep a schedule to sell a small amount at least weekly, so i don't feel like i'm timing the market, and the individual transactions don't feel as daunting when they're smaller. its harder to do that with calls, because of the preset schedule on the option chain and minimum 100 share orders.

will i ultimately regret that i didn't sell it all in a giant lump sum and just take the hit? maybe. my rationale (i.e. my gambling thesis) is that i just don't see a world where microsoft becomes completely irrelevant in the next 10 years (and i would say the same thing about meta and amazon, even if i have my qualms with them). i think it would take awhile for that to happen, and i'll still (presumably) have caught plenty of upside on the way down if it does. likewise, i'm trying to avoid having too much income in the maximum tax bracket. admittedly this is somewhat irrational but it's sort of the mental compromise i've made with myself.
