usmannk··on Space Debris Has Hit and Damaged the International Space Station
Thanks, I thought it was an unusual colloquialism for "couple of"
usmannk··on Microsoft president: Orwell’s 1984 could happen in 2024
hence the, presumably tongue in cheek, "paraphrased superaccuratequote" warning
usmannk··on Adjustable recipe
who knew, only ~30C of flour for `1e+64` donuts
usmannk··on Ask HN: How much do you contemplate per week?
At least in the US, where and were are pronounced differently.
usmannk··on Vulnerability allows cross-browser tracking in Chrome, Firefox, Safari, and Tor
hm, I tried this on 2 browsers and it said I was unique both times. Shouldn't the second have been a collision?
usmannk··on Does NMN improve metabolic health in humans?
not the same person
usmannk··on Show HN: A Chrome extension to see notifications for comments on your HN threads
Why not drop a local cookie yourself for state?
usmannk··on They Just Moved to Austin. Now They Want to End One of Its Traditions
All the way down to "Cesar Chavez"
usmannk··on Show HN: Cloud GPUs for Deep Learning – At 1/3 the Cost of AWS/GCP
Ah gotcha, did you have to move them to your DC and have them racked?
usmannk··on Show HN: Cloud GPUs for Deep Learning – At 1/3 the Cost of AWS/GCP
This is seriously cool. I want to mention that on AWS you can reliably get V100's for $0.918/hr (I do this all the time) by using spot instances. The spot price hasn't changed by even 0.01 for at least a year, so you're extremely unlikely to get an unexpected shutdown. Also, how did you manage to get V100s? What was that like?
usmannk··on I bought 300 emoji domain names from Kazakhstan and built an email service
> I recall some newspaper (NYT? News Yorker?) failing to test for that when people want to bypass their paywall.

For a long time I could access Bloomberg for free because they failed open when you did this

usmannk··on Show HN: Ten seconds to ponder if a thread is worth it
I think it's to stop the HN equivalent of "doomscrolling" or mindlessly wasting time. If you have to wait then there's time to think, ok should I even be doing this right now?
usmannk··on A Vim Guide for Advanced Users
Why is this preferable to :%s?
usmannk··on Lena
My first thought was that this reminded me of an epileptic seizure brought on by "fuzzing" (sensory overload)
usmannk··on Abundant Capital
a) "epistemic arrogance" -- you believe you're smarter and know more than everyone else;

No, more like you decide to be less greedy than everyone else. You choose to leave money on the table in favor of getting out early.

usmannk··on Show HN: An Event Sourced Minesweeper
Really fun to finish and draw the slider backwards. Revealed a spiral pattern I didn't realize I was doing!
usmannk··on ‘Roaring Kitty’ Sued for Securities Fraud over GameStop Rise
This wasn't a pump and dump though. Even if it never hit WSB the pump (squeeze of the short sellers) would have happened. The defining feature of a pump and dump is a socially engineered pump. Here the social aspect was more like "Look what is going to happen with or without us, we should ride it up. It is also obviously going to crash right after". People from WSB to Scion capital saw this coming, and got in.
usmannk··on Are the New M1 Macbooks Any Good for Deep Learning?
Training? No, of course not. It's still a laptop GPU/SoC/"Neural Engine"/whatever. Especially when the alternative is free GPU via Google Colab etc, there is no competition.
usmannk··on IMF researchers: digital footprint yields better credit assessment
[Edit: no longer relevant, see replies] No it doesn't? This is the only part of the post relevant to the headline:

> The second and most complex problem is that certain kinds of people, like new entrepreneurs, innovators and many informal workers might not have enough hard data available. Even a well-paid expatriate moving to the United States can be caught in the conundrum of not getting a credit card for lack of credit record, and not having a credit record for lack of credit cards.

> Fintech resolves the dilemma by tapping various nonfinancial data: the type of browser and hardware used to access the internet, the history of online searches and purchases. Recent research documents that, once powered by artificial intelligence and machine learning, these alternative data sources are often superior than traditional credit assessment methods, and can advance financial inclusion, by, for example, enabling more credit to informal workers and households and firms in rural areas.

usmannk··on Robinhood denies claims that it sold GameStop shares out from under its traders
Firstly, this isn't true. Just this week AMC was trading tens of billions of dollars worth of shares per day, which is about equal to AAPL. GME is seeing >twice as much.

Second, the insane amount of volatility and concentration in these tickers makes the clearinghouses charge the brokerages way way more. You have fees (quoted in %) for expected change and also lack of diversity.

usmannk··on New Intel CEO rehiring retired CPU architects
New grads in SFBA make well north of $75/hr. Sometimes it's all about geo.
usmannk··on Bitcoin: Magic Internet Money
Is discussing a venue for (possible, depending on your location) tax fraud equivalent to admission of participating in tax fraud?
usmannk··on What Is a Gamma Squeeze in the Context of Stock Trading?
Very very good primer by Twitter user @squeezemetrics: https://squeezemetrics.com/download/The_Implied_Order_Book.p...

usmannk··on Resolving the Time Paradox Implied by Functional Programs
I don’t recommend this strategy in practice though. It’s brittle and not all application state can even be represented as UI (what about your login cookie?).
usmannk··on Resolving the Time Paradox Implied by Functional Programs
Consider pressing a "play" button to first start playing the video but then also remove itself from the UI and replace it with a "pause" button that when clicked does the inverse. The UI here is acting as a state store but the functions can then be designed as purely functional, acting only on their inputs.
usmannk··on Show HN: Find the safest well lit walking route between two locations
The most direct route (stockton->market->howard) is actually the one I’d take in that case. What do you think it should suggest?
usmannk··on About Google's approach to research publication – Jeff Dean
From what I read it sounds like Timnit cleared the general idea of the paper 2 months before. The paper itself seems to have been submitted for approval 1 day prior to the deadline. Another HN commenter says that submitting papers for approval "hours" before the deadline is common at Google.
usmannk··on Amazon EC2 Mac Instances
How are you developing iOS apps without xcode?
usmannk··on How fast does interpolation search converge?
Is the trick quit and start doing a binary search?
usmannk··on Jane Street Market Prediction ($100k Kaggle competition)
Generally this is allowed if you publish the data you're bringing in. They even create a sponsored thread for it in most competitions.
