> To visualize $1.5 billion: if you cashed that check out in $100 bills and stacked them one on top of another, it would reach a five story building. For ordinary plebeians like us, at the average US salary of around $75K, you’d need to work 20,000 years to earn that.

No, we don't need to visualize that.

It also seems, really low?

A stack of bills is roughly 0.5 inches. Assuming a 12-ft joist-to-joist spacing, that's 12 feet per floor \times 12 inches per foot \times 2 stacks per inch = 288 stacks per floor = $2.88M per floor since a stack of 100s is $10k

So that would be a 1,000M / 2.88M ~ 347 story building.

Or is my unit conversion wildly off from dealing with sick kids over the holidays?

I'm curious how much this costs to run. I.e., how much are you paying for electricity?

chasely · 5 months ago

Not sure about this one in specific but assuming most of the time the system is idle at ~200W, you’d be looking at ~$25/mo for most states in the US.

Peak draw could probably be 2kW for a beefy system so electricity costs could really skyrocket depending on usage patterns.

I tell my kid that math is a language. You learn to speak it, just like you learn to speak any other language, slowly, by listening, understanding, speaking, intuitively recognizing patterns, rules and exceptions. When you start to become fluent you translate problems into math and solve them. At school they keep trying to make them memorize useful phrases, like a tourist that goes to Paris and learns how to say "where's the bathroom", "hello", "would you like to sleep with me", "thank you", "goodbye", etc.

Quite a story condensed into those five phrases.

Does anyone have a solid road map of what to learn to get to the point where learning stochastic calculus is possible? I have a CS degree that was obtained 8-10 years ago. What are the prerequisites?

chasely · a year ago

A few weeks ago I decided I wanted to get into this so I started self-studying probability theory (with measure theory) [0] as a bridge to start in on stochastic calculus [1]

I think the hardest part of self-studying anything that has some formal math foundations is knowing _what_ to pay attention to. There's so much in just the first chapter of the probability book. Is having a general understanding of set theory enough or should I actually know how to prove a function is a singular function?

That's why I often like to find a university course with lectures posted online so I can use that as a rough guideline for what's important, but I haven't quite found that yet for stochastic calculus. Would love if someone coul point me to one.

Still broken though! Has been for years. In a recent GH issue regarding desires for the reboot, I asked: "Try it on a few different machines (OS, GPUs, CUDA versions etc), make it work on modern RustC and CUDA versions without errors." The response was "That will be quite some work." Meanwhile, Cudarc works...

Totally, it's going to take a minute to get it all working. On a positive note, they recently got some sponsorship from Modal [0], who is supplying GPUs for CI/CD so they should be able to expand their hardware coverage.

Rust support next? RN I am manually [de]serializing my data structures as byte arrays to/from the kernels. It would be nice to have truly shared data structures like CUDA gives you in C++!

chasely · a year ago

The Rust-CUDA project just recently started up again [0], I've started digging into it a little bit and am hoping to contribute to it since the summers are a little slower for me.

Almost everyone I know got several hundred thousand dollars gifted for a down payment and most of these people are from typical middle or upper middle class backgrounds. I have a top 2% income (by Canadian standards) but the best I can do is a 2 bedroom condo or a bottom of the market townhouse with a long commute

I don’t know a single neighborhood in this city where the average household in that neighborhood makes enough to live there with current prices.

I genuinely don’t know why I even work anymore. I don’t have any achievable financial goals except save as much as I can until I move away to live off my savings in a cheap area

chasely · a year ago

I see this a lot as someone that came from a solidly middle-class background (parents were a teacher and secretary) and went to a "highly-ranked" university with plenty of upper-middle or upper class students.

I work in the same jobs as my peers, but there is a clear wealth difference in how our lives are spent.

We have a nice house in a good neighborhood, but our peers have very nice houses is some of the best neighborhoods due in large part to down payment gifts, gifts for remodeling, etc. We can both afford the mortgage payment, but the down payment would take us probably a decade to save for.

On vacations, we'll drive a couple hours away with the kids, while our peers will fly to Europe and spend two weeks since they pay for the flights and their parents pay for lodging and food.

And then there is family support. Some of my peers have parents who bought second (or third) homes to be closer to their grandchildren, or will pay for the very nice private school, etc.

It's taken me a lot to not very bitter about this -- and I'm clearly still a little bitter -- but I also know that we will likely be in a position to offer some of this support to our kids in 20+ years.

I'm concerned about my US bonds, as the way to access them is through a government website. Are these people going to block my access and steal my money?

I'm trying to download my 1099 forms from TreasuryDirect and it's coming back as unavailable. Probably unrelated to everything going on now, but the fact I thought that it could be related for a second is crazy.

>>> TreasuryDirect is unavailable. >>> We apologize for the inconvenience and ask that you try again later.
