traek··on Scalable Bloom Filters (2007) [pdf]
Bloom filters are popular mostly because they’re clever, but they can also be useful.

E.g. Google Chrome’s safe browsing feature used Bloom filters to check whether a site might be flagged for malware, and if necessary query Google to check if it is actually flagged. It would have been impractical to download the full safe browsing dataset to every client, and also impractical to query Google for every single site visited. Bloom filters were a good solution (note: they’ve since moved to a custom data structure[1] which is also interesting.)

traek··on Facebook lost around 2.8M U.S. users under 25 last year
In what sense do you think a driver’s license is a “treasure trove of personal information”? Especially information which FB does not already have from other sources?
traek··on Instacart has raised another $200M at a $4.2B valuation
Amazon Fresh is a different service from Prime Now. Prime Now also delivers from local grocery stores (e.g. in LA, I can order groceries from Sprouts and Bristol Farms).

traek··on A pessimistic vision of India’s looming environmental and economic collapse
No, they could believe that UK assets have a different risk profile than US assets and want to diversify, even if they think UK assets have a lower risk-adjusted return. Diversification is valuable.
traek··on The Philosophy of the Midlife Crisis
The subject of this article, Kieran Setiya, also published a piece called "How Schopenhauer’s thought can illuminate a midlife crisis"[1] which generated interesting discussion on HN [2].

How has China forced companies into tech transfer? Nobody forces them to manufacture in China.
traek··on A pessimistic vision of India’s looming environmental and economic collapse
This was primarily to reduce exposure to US assets, not to specifically gain exposure to UK assets. In fact, if you look at their holdings you’ll see the relative percent increase is much lower for Sterling than Euro, which could signal lower confidence in GBP than EUR.

Funny enough, we actually did drain and pave most of the canals in Venice, California.

As far as I can tell, the founders are Irish but the company has always been American.

traek··on America's Love Affair with Avocado
> The post I replied to is claiming that they lose money on each sale of guacamole. (This is clear from bringing up the possibility of raising prices of the optional add on guacamole.)

That's not what they're claiming, they're saying that if ingredient prices rise (e.g. for avocados) Chipotle can raise menu costs to protect margins. Nowhere is it implied that guacamole was being sold below-cost.

Caffe2 is a Facebook project, so they’re not exactly being “forced” to release it or any downstream projects under Apache 2.

This is pretty common for MDMA pressed pills.

They’re referred to by the logo, e.g. “orange teslas” or “purple instagrams”. See [1] for photos of pills with the Instagram logo.

Yes, they did. Salesforce Tower’s foundation is anchored into bedrock.

This is both easy to look up and not relevant to the conversation about design.

You misunderstand supply and demand. Consumers can be (and are) priced out of the housing market just as they can be priced out of any market.

Which economic laws dictate that?

On a related note, Red Bull funds a lot of programs for up-and-coming artists[0] as well as subsidizes as a concert series[1]. It's good for branding.

traek··on Show HN: Effects of House and Senate Bill on California Residents
What is the poor assumption that s/he is making?
traek··on Show HN: Effects of House and Senate Bill on California Residents
You're simply wrong. Higher-income college students are far more likely to go to graduate school than lower-income students.

> The percentage of students enrolling in graduate school increases with family income. Among dependent 2007–08 four-year college graduates, 39 percent of those from families in the lowest income quartile, 42 percent from middle-income families, and 45 percent from the highest income quartile had enrolled in graduate school within four years of college graduation. [0]

It's also misleading for you to look only at figures for STEM fields, in which international students are much more highly represented than other fields. I'm not sure why you're using looking at STEM only and using that to prove your point. The NYTimes article you linked says it best:

> "in arts and humanities, the figure [of students which are international] was about 16 percent; in business, a little more than 18 percent."

Providing tax breaks for graduate school does disproportionately benefit the upper middle class and the wealthy.

traek··on The Problem of Doctors’ Salaries
S/he’s saying that this argument

> they've calculated that the marginal benefit from accepting a single resident at a lower cost does not outweigh the risk of being forced to provide the same discount to their existing residency positions.

only holds up for schools with existing residency positions, which there are many without. If a residency were profitable without the subsidies, one would expect to see those non-teaching hospitals launching residency programs. Especially so because they don’t have to worry about threatening the subsidies which they aren’t receiving.

traek··on Blue-collar wages are surging. Can it last?
> there's a long time delay between when demand rises and when supply can rise to meet it

Yes, exactly. The demand curve shifts right and the markets find a new equilibrium (most likely at a higher wage than the old equilibrium), but there’s no “shortage”. It’s just markets clearing at a different price level than what people are used to.

Calling it a “shortage” is like saying every time Starbucks raises their prices there is a shortage of coffee — at the old price, sure, but not in absolute terms. That’s not how equilibriums work.

traek··on How Politics and Bad Decisions Starved New York’s Subways
> New York election law is incredibly arcane and structurally makes it almost impossible to win a primary without the backing of the party, and the two parties have an agreement not to compete seriously in each other's districts. It's like how Comcast and Time Warner Cable divide up turf, so they don't ever really have to compete for the same customers.

Can you give an example of these election laws? I see you mentioned a delay in switching parties elsewhere in the thread, but I don’t see how that makes it impossible for a candidate to win a primary without party backing.

That is what is happening at the MTA.
