thomaspaine··on Jepsen: TigerBeetle 0.16.11
I work on the ledgering system at clear street and as far as I know we have no plans to do this. We evaluated it internally a few years ago and found that the account and transaction model was too different from ours to migrate over.
thomaspaine··on No amount of alcohol is good for the heart, says World Heart Federation
For everyone complaining about evidence citation, this is just a press release. The actual brief which includes 41 citations is here: https://world-heart-federation.org/wp-content/uploads/WHF-Po...
thomaspaine··on Andrew Ng: The suspension of H1B is bad for the US and bad for innovation
>I have worked with Indian subcontractors that have waited 20 years!

And you think this suspension will help them?

thomaspaine··on Andrew Ng: The suspension of H1B is bad for the US and bad for innovation
ITT: People criticizing the H1B program for reasons that have nothing to do with why it was suspended, or considering the fate of people/families who are already here on H1Bs.

This is a pretty obvious move by the administration to discourage immigration, in any form. Could the H1B system be more equitable to workers, more efficient, less confusing, etc? Absolutely. But suspending H1Bs and green card applications like this does the opposite of all of that and throws thousands of families into limbo.

thomaspaine··on How to be successful (at your career, Twitter edition)
>Getting caught up in the parts of a job that don’t matter is a dangerous trap and for some reason one that a lot of people fall into. Let other people play political games and avoid them as much as you can.

My experience at big companies is the inverse. The people who advance are the ones who spend 80% of their time focused on politics, while the heads down engineer will get a thank you and inflationary raise.

thomaspaine··on Ten Rivers Contribute Most of the Plastic in the Oceans (2018)
You're not wrong, this headline is very poorly worded.

From the article:

>A recent study estimates that more than a quarter of all that waste could be pouring in from just 10 rivers, eight of them in Asia.

>The 10 rivers that carry 93 percent of that trash are the Yangtze, Yellow, Hai, Pearl, Amur, Mekong, Indus and Ganges Delta in Asia, and the Niger and Nile in Africa.

So to say "10 Rivers Contribute Most of the Plastic in the Oceans" is not really correct, they contribute something like 25%.

thomaspaine··on The Effectiveness of Publicly Shaming Bad Security
Law suits seem to be the standard tactic for dealing with other types of corporate negligence (for better or worse). Why aren't they employed more for these types of obvious security vulnerabilities if you can demonstrate harm?
thomaspaine··on Wall Street’s Big Banks Are Waging a Technological Arms Race
> The cause? A coder had mistakenly programmed a router to send placeholder bids as live orders. If not for the good graces of the options exchanges, the bank would have lost $500 million, according to the U.S. Securities and Exchange Commission. Cancellations and price adjustments reduced that to $38 million

It's interesting to read the full SEC report because it's a little more complicated than that: https://www.sec.gov/litigation/admin/2015/34-75331.pdf

It basically outlines a cascade of failure in controls, bad configuration defaults, and poor SDLC. In particular:

>In addition, the firm’s operation and management of its electronic “circuit breakers” did not effectively block the erroneous orders sent on August 20. These circuit breakers existed to prevent erroneous orders by halting all message traffic to the exchanges once that traffic had exceeded a certain rate. However, on August 20, the firm’s control personnel repeatedly lifted the circuit breakers blocks between 8:44 a.m. and 9:32 a.m., thereby permitting additional erroneous orders to be sent to the exchanges. Before lifting the circuit breaker blocks, the control personnel did not obtain authorization from the responsible technology employees, as required under written firm policies.

>The firm’s policies relating to the manual “lifting” of those circuit breakers were not disseminated to or fully understood by the employees responsible for deciding when the circuit breakers should be lifted, and, prior to August 20, 2013, GSCO personnel had lifted circuit breaker blocks shortly after learning of the block and while still investigating the cause of the circuit breaker trip.

From what I remember, this circuit breaker was notorious for raising so many false positives that control personnel just got used to lifting it without thinking.

thomaspaine··on Ask HN: What information should be in any job description page?
Why can't you publish multiple salary ranges per job post (level 1: $X1 - $Y1, level 2: $X2 - $Y2, etc) or multiple job posts (one for each level)?

Neglecting to publish a salary range seems more like a negotiation tactic on behalf of companies of not wanting to be the first to name a number. Either that or you know your company can't compete on salary, which is my typical assumption when it's a company I've never heard of and I don't see a range provided.

thomaspaine··on Show HN: Quantra.io, a quantitative finance API made with Quantlib
As someone who works in a bank, if I sent trading data off to an external service I'd be fired almost immediately. Even things like pretty printing services are monitored and blocked.
thomaspaine··on Goldman Sachs Dumps Numerical-Ranking System for Employees
>I distinctly remember that most of the mean scores were between 8 and 9. One was as high as 8.7.

I was told by several people that the ratings are normalized to adjust for this.

thomaspaine··on Markov Chains Explained
Markov chains have a lot of nice features you can derive from them, like convergence to a stationary distribution. It's hard to say that it's an inappropriate simplification if it happens to be pragmatic (like most simplifications).

For example PageRank can be modeled using markov chains. You can surely develop more complicated models but markov chains provide a good starting point.

thomaspaine··on Rental America: Why the poor pay $4,150 for a $1,500 sofa
>neither Wal-Mart nor Jack’s nor the nursing home cafeteria have shown interest in an applicant with psoriasis and a ninth-grade education.

People who only have ninth-grade educations aren't the greatest at basic math or delayed gratification.

thomaspaine··on Ask HN: What is REST exactly?
REST doesn't have to be JSON, it's agnostic with regard to the serialization format. JSON is just a popular format but I've seen XML and YAML REST apis.
thomaspaine··on Protean Echo – Fuse All Your Cards into One
I have the Costco Amex too, but how often are you going to Costco that you're carrying it around everyday?
thomaspaine··on Protean Echo – Fuse All Your Cards into One
Why do you need to carry around four debit cards and a backup credit card? I'm not saying this works for everyone but my wallet contains $20, a driver's license, and a credit card.

If I'm going to be somewhere where I might need a business CC or debit card then they're temporarily added. Otherwise I store all my CC info in 1password anyway which I can access on my phone.

thomaspaine··on Is The Economist left- or right-wing?
How so? "Classically liberal" is a way of differentiating oneself from the modern definition of liberal and is basically a friendly way of saying "libertarian" without invoking images of Glen Beck.
thomaspaine··on Banksy Art Sale in Central Park [video]
It's a cool experiment but not altogether surprising right? The provenance of a piece of artwork, and other rare goods, is arguably more important than the art itself. Especially in the case of artwork which is easily reproducible and copied.

If you think that's idiotic then ask yourself if you were given the opportunity to buy the first original Apple 1 or an exact replica, how much more would you be willing to pay over the replica? If the amount is greater than zero, then you're admitting that you're really buying an experience and set of emotional states in addition to a physical good.

thomaspaine··on The Stanford Academic Who Wrote Google Its First Check (2012)
I don't think he's implying social networking will go out of fashion, but that social networking companies themselves can be fashionable. For instance the progression of "cool" social networking sites seems to progress pretty rapidly e.g. myspace -> facebook -> twitter -> instagram -> snapchat.

To put it in Steve Blank terminology he likes to invest in companies that face invention rather than market risk.

thomaspaine··on Clang game project has run out of money
You should finish the quote...

>Kickstarter is amazing, but one of the hidden catches is that once you have taken a bunch of people's money to do a thing, you have to actually do that thing, and not some other thing that you thought up in the meantime.

His point being that Kickstarter funding makes it hard to pivot, as opposed to other types of funding.

thomaspaine··on Bitcoin is Deflationary, and That's OK
Small nominal inflation encourages investment, whereas deflation incentivizes people to just hold their money in the form of cash.
thomaspaine··on If you get a PhD, get an economics PhD
>in the world of calibration in macroeconomic models, the creator of the model is now testing data against theory by tuning parameters to values they think are good. It is completely backwards.

This is a little inaccurate, the purpose of these macroeconomic models is either to make future predictions or run simulations to see what happens when exogenous shocks occur. They're not "testing data against theory", the data is used for parameter estimation and then verifying the accuracy of the models. It's actually very similar to the way certain AI models are developed and trained.

I do agree that these models are usually pretty inaccurate and somewhat useless though.

thomaspaine··on Andrew Ng and the Quest for the New AI
Grok (formerly Numenta) has a slightly more technical white paper that goes into more detail on the actual algorithms from On Intelligence:

https://www.groksolutions.com/htm-overview/education/HTM_Cor...

There are some subtle differences between HTMs and straight up deep learning, mainly the requirement for HTM data to be temporal and spatial.

I know Andrew used to sit on an advisory committee at Numenta, I don't know if he still does.

thomaspaine··on US Senate approves proposed Internet Sales Tax
Is a $50,000 car a necessity? $20,000? $10,000? Is a car a necessity at all?

How about food? Is a $250 dinner at Saison a necessity? $5 dinner at McDonalds? $20 per pound imported beef at the grocery store?

$200 jeans vs $80 vs $20?

Are glasses a luxury item? How about Google Glasses?

How do you define it? The devil is always in the details with laws and especially tax law, you can't just hand waive this kind of stuff away.

thomaspaine··on It’s a part of my paleo fantasy, it’s a part of my paleo dream
>Probable or definite atherosclerosis was noted in 47 (34%) of 137 mummies and in all four geographical populations: 29 (38%) of 76 ancient Egyptians, 13 (25%) of 51 ancient Peruvians, two (40%) of five Ancestral Puebloans, and three (60%) of five Unangan hunter gatherers (p=NS).

I think the point is that atherosclerosis was just as prevalent in the hunter gatherer society as it was in the agricultural ones. Sample size is admittedly small though.

It's bad, but I would say its notoriety comes more from the fact that it's so bad relative to the neighboring blocks. Walk two blocks and you're at the Westfield mall / Union Square.

thomaspaine··on Sweden imports waste from European neighbors to fuel waste-to-energy program
Is incineration really the more environmentally friendly way to go? How does this compare to something like coal in terms of environmental impact? I'm imagining giant trash furnaces spewing ash and smoke into the sky but I'm guessing that they're using something more sophisticated.
thomaspaine··on What's a $4000 Suit Worth?
The reason you see made-to-measure more so with suits as opposed to more casual wear is because suits are highly structured garments. They have to fit correctly in a lot of different places, whereas knitwear like t-shirts and polos stretch and the same size can accomodate a wider variety of body types. There are lots of places that will do MTM casual button ups.

I have several MTM shirts and suits, and honestly I don't think it's really worth it. For a couple reasons, I'm much happier these days finding a brand that fits me off the rack and having it altered if necessary.

1. The grand promise of MTM is the perfect fit, but your first one or two attempts are almost certainly going to leave you with a garment that doesn't fit. At best, this requires more fittings, trips to the tailor, and time. At worst, you're stuck paying for a garment that you will never wear and cannot return.

2. MTM will always be more expensive. For example, Indochino suits are pretty cheap ($400), but for the same level of construction and fabric you're looking at a a $200 suit from Men's Warehouse. J. Crew sells $130 Thomas Mason shirts, and to get the same shirt MTM from my Hong Kong tailor costs me $200.

thomaspaine··on What's a $4000 Suit Worth?
What does this have to do with anything other than that both articles happen to use the word "suits"? This isn't a story about the suit making a comeback, it's about old world artisanship struggling to survive in a 21st century economy.
