te··on Hasse diagram of the 2008 Olympic medal table
Where I'm from, it's "inarguable" that [1,0,1] > [0,2,0]; that is, that a gold and a bronze is better than two silvers. This would break some of the ties shown in the diagram.
te··on How to compare two functions for equivalence, as in (λx.2*x) == (λx.x+x)?
Term rewriting might help.

te··on Real estate site Redfin files for IPO
So you reduce the top-line offer by 3%? Or, if your written offer specifies 3% back to you, how does the seller's agent manage to take 4% in contradiction to the offer? Not sure what jurisdiction you're operating in, but I wasn't aware that offers could dictate chagnes to the terms of a pre-existing listing agreement between the seller and their agent. Would love more details on how to effect something like this.
te··on Show HN: Insect – a high-precision scientific calculator with physical units
I'd love a calculator that can implicitly recognize hh:mm:ss notation and can answer queries like ...

3:20:36 / 26.2

7:35 * 26.2

te··on Death by Fire
Norman Maclean's "Young Men and Fire" tells the story of the Mann Gulch incident. Recommended.
te··on Ask HN: What is the most exciting development in your field right now?
Your interesting comment made me think of Oblique Strategies cards, which "can help someone solve an issue without actually knowing the details".

te··on A disaster is looming for American men
Without any evidence whatsoever, Larry Summers posits that the four-decade long trend of an increasing share of young men not working implies "job destruction caused by technology".

Instead, I think this trend is far more likely to be caused by an increasing share of young women entering the workforce over the same timeframe.

te··on Human skeleton found on famed Antikythera shipwreck
I want to know more details about a "war dolphin", but the Internet doesn't seem to know about it.
te··on Association Between Cesarean Birth and Risk of Obesity
Yes. The paper's abstract only notes an 'association', not a causal arrow. Readers simply infer the causal arrow.
te··on How I wrote and published my novel using only open source tools
I love Paperpile, which would accommodate some/many of these needs.
te··on Musk Declares Tesla Free of Factory Hell with Targets Intact
That article is two years old.
te··on Musk Declares Tesla Free of Factory Hell with Targets Intact
No, they forecasted production of 20,000 cars. They forecasted deliveries of 17,000 cars. Substantial miss on both counts.

Edit: fixed link to correct source, as pointed out below. In this pdf, it's on bottom of page 3, under "Outlook".

te··on Doing Bayesian Data Analysis On the GPU: Examples
Looks cool. Would love to see the "much, much faster" claim quantified. Both including and excluding compile times. Stan is neat, but the recompile time after every tweak to the model really got to be a drag. If you can improve on that, it would be a real win for me.
te··on Distinguishing Cause From Effect Using Observational Data
Interestingly, the authors do acknowledge on p. 46 that their sample size is too small to obtain a statistically significant result:

A rough estimate how large the CauseEffectPairs benchmark should have been in order to obtain significant results can easily be made. Using a standard (conservative) Bon- ferroni correction, taking into account that we compared 37 methods, we would need about 120 (weighted) pairs for an accuracy of 65% to be considered significant (with two-sided testing and 5% significance threshold). This is about four times as much as the current number of 37 (weighted) pairs in the CauseEffectPairs benchmark. Therefore, we sug- gest that at this point, the highest priority regarding future work should be to obtain more validation data, rather than developing additional methods or optimizing computation time of existing methods. We hope that our publication of the CauseEffectPairs benchmark data inspires researchers to collaborate on this important task and we invite everybody to contribute pairs to the CauseEffectPairs benchmark data.

te··on Who pays when startup employees keep their equity?

  > 3 year employee tenure
  > 100% loss of potential equity when employees leave the company ...
  ...
  > You can also see that only the employees hired in year 8, 9, 10 
  > (the final 855) have any shares at the end of year 10. Quite bizarre!
Yes, quite the mystery indeed.
te··on Tesla's 'Autopilot' Will Make Mistakes. Humans Will Overreact
Is Tesla's autopilot using radar? How is radar fooled by a white truck against a bright background? I was surprised by this point of failure, which suggests to me that they aren't even using radar.
te··on How 'Advantage Players' Game the Casinos
What are the "newer blinded player methods"? Google only finds your comment.

How did you value the options?
te··on The Quickest Way to Understand VC
> "They aren’t looking for a guaranteed $1M, they want a chance at $1B or $100B. This is really weird, because software business that are profitable might not be fundable."

Huh. Sounds like an inefficiency on the funding side. Or is it that these biz's profitability typically enable self-funding? Why does a profitable startup that doesn't have VC-style growth potential need funding?

te··on New Dilemmas for the Prisoner (2013)
Not a book, and I wish it wasn't so expensive, but this is excellent: http://www.thegreatcourses.com/courses/games-people-play-gam...
te··on Go, Marvin Minsky, and the Chasm That AI Hasn’t yet Crossed
After reading the DeepMind paper, it does seem like their techniques could also be applied to chess and could possibly improve the state-of-art there as well. It is unclear, however, how much improvement remains in modern chess engines. They are already phenomenal.
te··on Headphone and Amp Impedance (2011)
I use an Acer C720 Chromebook running Linux to drive my virtual piano software. I had no complaints with it's on-board audio performance, but after reading multiple exhortations on the internet about how much better external soundcards are, I bought a $5 USB soundcard widely available from multiple vendors on ebay. OK, I can just barely hear an improvement over the on-board. It's better in the sense of "significant" (ie definitely there), but it just isn't a material difference to me.

If I'm that deaf to the differences between these two sources, I'm curious if people think the UCA202 will change my life?

te··on Finding the Tennis Suspects
I have no problem believing that there is match-fixing in tennis, especially among the non-elite ranks. However, it is still an extraordinary claim, and as such, requires extraordinary evidence. They have examined a dataset that includes match losses by 1,509 unique players. Among others, they have accused a fellow whose match results, by their own estimation, are 4.7% likely to have occurred by chance. If you're going to be involved in throwing around accusations of this magnitude, I'd like a little more rigor in the statistics. I don't know how they sleep at night.
te··on Optimization story: Switching from GMP to gcc's __int128 reduced run time by 95%
This is seriously awesome. Got to love when you make a blog post about a 20x speedup, and the internet returns the favor with an Infx speedup.

Serious question: can I record streams from Sling TV so I can watch on my schedule and skip commercials?

If someone does a remake of Back to the Future, Doc Brown should have a robotically-operated klein bottle warehouse under his house.
te··on I am Sam Altman, President of Y Combinator – AMA
Colin, given that you don't want to live in the Bay Area, how do you envision yourself being a part of the YC community? These propositions seem fundamentally at odds with one another. Given that restriction, however, here are some ideas:

Could you arrange to go down to YC periodically and hold "office hours" to begin relationships with founders that are doing interesting things in your areas of expertise?

Could these relationships lead to you becoming a technical advisor for some of them?

Could you angel invest in some of them?

Could you attend YC investor day?
