sethev··on Google Fires Employee Behind Controversial Diversity Memo
His argument seems to boil down to "men and women are different, maybe that's why there are fewer women in tech". That's not an argument, it's speculation that there's an argument. The bulk of the manifesto is a repetition of tropes about men vs women.

Having a phd in biology doesn't prevent someone from being wrong
sethev··on Bitcoin – Potential Network Disruption on July 31st
Even if you spread Visa's transactions evenly over time, the 100 billion transactions per year [1] that they perform would be a couple orders of magnitude higher than what bitcoin can support (~3000 TPS)

sethev··on Unikernels are secure
A unikernel is running a single process in a single address space. So yes, if you compromise the app you compromise the whole system but the whole system is the app.
sethev··on How do whales and dolphins sleep without drowning?
I'd be cautious of answers to questions like that that sound like a story. But it's worth pointing out that the ancestors of whales started out on land and it's not necessary to imagine they jumped straight from that to fully aquatic.
sethev··on Delivering Billions of Messages Exactly Once
There's also a race condition in there when you receive the duplicate before publish_and_commit is done doing its thing - assuming they're not actually serializing all messages through a single thread like the pseudocode implies.

What they've done is shift the point of failure from something less reliable (client's network) to something more reliable (their rocksdb approach) - reducing duplicates but not guaranteeing exactly once processing.

Accenture revenue in 2016, $32.9 billion. Consulting definitely scales.
sethev··on 1Password Travel Mode: Protect your data when crossing borders
This issue seems to be a bit of a geek trap. Yes, border agents have a fair amount of authority. No, you're not required to twist your mind into a pretzel trying to decide whether what you choose to put on your device constitutes hiding the things you left off. If an agent is asking you something as specific as "did you enable travel mode in 1password" you've probably already triggered some suspicion.

Some of the responses on this thread make it sound like there are people who would actually start explaining travel mode unprompted because they arrived at it by some twisted logic about what 'hiding' means.

sethev··on 1Password Travel Mode: Protect your data when crossing borders
If the question is "are you hiding any information" then the obvious (and true) answer is no. If the question is "did you use travel mode for 1password" then that's a very different question. Unless you can point out a statute that requires you to travel with certain information on your device it's hard for me to see the problem.

Your position seems to be that if you were carrying your checkbook (as an American) and then decided against it because you were worried someone might get your bank account number then you somehow risk getting into a debate over technicalities with a border agent. I would strongly recommend not getting into that debate as well by not bringing it up.

sethev··on 1Password Travel Mode: Protect your data when crossing borders
So are you required to have all the data that's ever been on your device at the time that you cross an international border? Are you required to copy passwords that were never in 1password onto your device before you travel?

EDIT: Another way to put this: Is there an expectation that a border agent could, for example, ask for the password to my bank account? If not, how would there be an expectation that if that used to be on my iPhone it should still be there when I travel?

sethev··on The Evolution of Container Usage at Netflix
You seem to stumbling into the distinction between functional and non-functional requirements. Netflix spends massively more on content then tech so that's consistent with what you're saying. To use you're Disney example though, yes it would effect their success if they weren't able to deliver their content because their Bluray mastering expertise was lacking.
sethev··on Juicero founder defends machine
I really want somebody to cut one of those bags open - it's almost certainly already filled with juice. It seems unlikely that a person could manually squeeze the juice out of raw fruit this way.
sethev··on The Evolution of Container Usage at Netflix
How does the fact that other companies have streaming video services lead to Netflix not having to solve that problem? This seems a bit like saying that Walmart doesn't need to worry about managing their supply chain because Cosco has already solved that problem.

Also if you've ever tried a TV channel's streaming service you'll realize that recording the start and end time won't tell you much about the quality of the experience.

sethev··on The first woman to finish the Boston Marathon in 1967 has run it again at age 70
You're the one who's muddying the water by using a second sense of the word discrimination when everybody else is talking about the first.
sethev··on The first woman to finish the Boston Marathon in 1967 has run it again at age 70
You're mixing meanings of discrimination. Barring women from participating in an event is completely separate from how prizes are handed out. Mixing these two senses of the word 'discrimination' like your doing is equivocation. "Isn't it odd how people argue for equal rights but are perfectly willing to only turn left in some cases." No - it's not odd at all. Words can have multiple senses.
sethev··on The first woman to finish the Boston Marathon in 1967 has run it again at age 70
Do you feel the same way about age range based prizes or golf handicaps?
sethev··on Opaque drug pricing in the U.S.
Lack of transparency is an even greater fatal flaw in _non_ nationalized healthcare.
sethev··on Why Trello Failed to Build a $1B Business
Counterfactual history can be fun but it's highly speculative. That's true even for well studied historical events - it's even more true for something opaque like a private company's growth. What were Trello's main customer acquisition channels? Without knowing that how can you hope to derive an alternative history?
sethev··on I spent three months working full time to get a job
The grandparent post was pointing out that once you've decided to hire someone for one day they'll probably be around for at least 6 months. That's where the majority of the cost comes from.
sethev··on I spent three months working full time to get a job
"Managing someone out" is a large company concept. Once they realize the mistake, the owner of a small company can get rid of somebody immediately. It can take surprisingly long to realize there's been a hiring mistake, though.
sethev··on Richard Feynman and the Connection Machine (1989)
You're making a big assumption that he could have achieved the same result using the techniques that failed for the rest of the team.
sethev··on Warren Buffett's Annual Letter to Berkshire Hathaway Shareholders [pdf]
"My calculation, admittedly very rough, is that the search by the elite for superior investment advice has caused it, in aggregate, to waste more than $100 billion over the past decade."
sethev··on Amazon soars to more than 341K employees, adding 110K people in a single year
Sure - that's a plausible guess. It also didn't seem to bother his base.
sethev··on Amazon soars to more than 341K employees, adding 110K people in a single year
It may sound conspiratorial but Trump did say this about Amazon: "Believe me, if I become president, oh do they have problems, they are going to have such problems" [1] We'll see. [1]:https://www.theguardian.com/technology/2016/nov/18/amazon-je...
sethev··on Lyft surges to the top 10 on App Store following the “DeleteUber” campaign
That seems like an absurd splitting of hairs. Under that logic the concept of a strike breaker couldn't exist. "It was coal workers who were striking, but the replacements are not coal workers per se they were non-participating laborers who happen to perform the same function"
sethev··on Ask HN: What are good software architecture interview questions?
patio11's comment reads more like a method for evaluating answers. You present the candidate with a boiled down description of a real problem and then evaluate what they say against the rubric. All that to say you answer the questions by actually having expertise in the subject area of the question.
sethev··on Is Semantic Versioning an Anti-Pattern?
I thought he was advocating never introducing breaking changes.
sethev··on Ask HN: Bootstrapped US founders, who do you use for health insurance?
I'll throw another anecdote in there. The small consulting company I worked for up until 2014 switched over to reimbursing us for a portion of what we paid for an ACA plan. Before that we had a (very small) group policy that was incredibly expensive because of health problems that one person had. The ACA saved thousands of dollars in that case (without subsidies) just by having access to a larger risk pool.

I've heard people complain about ACA wrt to small business but it's always very vague general terms whereas the specific cases I know about were all positive.

sethev··on 'Legitimate' US healthcare pricing could reduce costs by a third
The current system sucks but I have trouble picturing your alternative. If a person has abdominal pain it could be caused any number of things - some of which could have no cure at all and some of which will just go away on their own. What price list could they possibly consult?
sethev··on 'Legitimate' US healthcare pricing could reduce costs by a third
The problem with this thinking is you don't know what services you'll require (apart from routine checkups and specific treatments for already diagnosed problems). It does me no good to have a list of all the thousands of possible things a hospital might do along with a price for each one.
