ccostes··on Amazon Go
Oh god, "Now where did the bread aisle move itself to today?"
ccostes··on Amazon Go
Considering there are no cashiers or checkout counters, cash seems like a no-go.
ccostes··on U.S. Citizens Now Hold About $1.3 Trillion in Student Loan Debt
How about giving back the diploma itself?
ccostes··on What.CD is shutting down
Hasn't heard of this before. Really interesting!
ccostes··on The real Soylent sickness
Somehow the same meal of neutral-tasing Soylent is more appealing than the same meal of some prepared food.

Maybe it's because drinking some Soylent isn't an 'activity' like eating a prepared meal is, but rather just something I do while doing something else, so I don't notice it as much (which I think is part of why it's designed to be neutral tasting).

ccostes··on The Government’s Addiction to ‘Secret Law’
Link has an extra semicolon at the end. Here's a working version: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2376272

EDIT: Just looking through the abstract I agree that it is a very scary assessment.

Abstract:

National security policy in the United States has remained largely constant from the Bush Administration to the Obama Administration. This continuity can be explained by the “double government” theory of the 19th-century scholar of the English Constitution, Walter Bagehot. As applied to the United States, Bagehot’s theory suggests that U.S. national security policy is defined by the network of executive officials who manage the departments and agencies responsible for protecting U.S. national security and who, responding to structural incentives embedded in the U.S. political system, operate largely removed from public view and from constitutional constraints. The public believes that the constitutionally-established institutions control national security policy, but that view is mistaken. Judicial review is negligible; congressional oversight is dysfunctional; and presidential control is nominal. Absent a more informed and engaged electorate, little possibility exists for restoring accountability in the formulation and execution of national security policy.

ccostes··on MailChimp’s founders built the company slowly by anticipating customers’ needs
> It's the only major city I've been to where a white person dropping the word "nigger" (and used in a clearly negative way) not only happens in conversation, but it doesn't elicit gasps or any negative response.

As a counterexample, I have lived in Atlanta for the past 7 years and never once heard anything like this. I'm not saying it doesn't happen, but it feels like you're painting the city with an overly broad brush.

ccostes··on Tup – A file-based build system for Linux, OS X, and Windows
Been using tup in production for about a year now and absolutely love it. The speed is nice, but compared to make projects where you need to 'make clean' to be sure everything gets properly rebuilt the confidence that tup will do the right thing every time is fantastic.
ccostes··on Ask HN: How to quantify that a team is overworked
Our development process is currently fairly unstructured. I think this would be a good way to get a better picture of how we're spending our time, but I'm worried about introducing too much overhead.
ccostes··on Ask HN: What do you wish someone would build?
I'm not sure anybody really knows the idea behind Google+.
ccostes··on Ask HN: What do you wish someone would build?
That's a pretty neat idea to use simulation as part of financial planning. I know I've seen general projections of retirement money, but using the simulation as an interactive tool to help tailor the plan makes it seem much more personalized and useful (though who knows if that is actually the case).

I'm not sure how successful this could be targeted at individuals without being integrated with some other financial product like a retirement account provider, though. It would certainly be nice to have something like Mint for retirement to consolidate and track overall allocations over many accounts from different providers.

ccostes··on Ask HN: What do you wish someone would build?
That's a pretty neat watch. Almost looks like a digital display rather than a mechanical device.

tcc?
ccostes··on House Passes Employee Stock Options Bill Aimed at Startups
Based on this short Wikipedia page [1] it sounds like it's done to avoid payroll taxes like social security and medicare.

Any other reason to do this?

ccostes··on Ask HN: Fulltime software engineers over 250k, how'd you get there(updated)?
NYC and Chicago seem to be the hotspots, but is anyone familiar with this sort of work going on in the Atlanta area?
ccostes··on A look behind the scenes at an index fund with Vanguard's Gerry O'Reilly
I've always wondered if there is a difference between the ETF version of the Vanguard funds and going directly to Vanguard. For the few I looked at it seemed like the ETFs had lower expense ratios and no minimum funding requirements.
ccostes··on How 'Advantage Players' Game the Casinos
Definitely interested in continuing the discussion. My email is in my profile, otherwise I'm not sure where you want to take it offline (just realized HN doesn't have private messaging).
ccostes··on How 'Advantage Players' Game the Casinos
Curious if you can share any more about your approach to fundamental investing. What stage/size companies do you focus on and how do you find an edge?

I looked into fundamental investing for a while but came away with the impression that you're trying to guess what the consensus of the market will be rather than finding some "right" answer. ie you can think the price should be x but if nobody else will buy/sell at x then you're wrong.

I've instead been subscribing to the notion that price movement can be thought of as random and selling option premium accordingly (the whole tastytrade mantra) but haven't been super successful and would be interested in hearing other approaches.

ccostes··on Michael Dell Bought His Company Too Cheaply
He does say in the footnote that he was kidding and that this is simply called "economics", if that makes you feel better.
ccostes··on Pebble 2, Time 2 + All-New Pebble Core
I'm currently sporting a Steel (the original) and went in for the new Time 2. Agree with comfydragon that the Time looks like the new version of the Steel line.

Wish they kept the leather strap, though, but maybe they will have different straps available down the road?

ccostes··on The Epic Rise of John D. Rockefeller
As I scrolled through I thought the same thing. I can't put my finger on it, but something about the photos is very off-putting.
ccostes··on GitHub is undergoing a full-blown overhaul as execs and employees depart
Hiring her to lead their diversity efforts doesn't count as endorsement of her views on diversity?
ccostes··on Unikernels are unfit for production
Ah, thanks for the correction. The controversy around unikernels makes a lot more sense now.
ccostes··on Unikernels are unfit for production
Reading through the article I feel like the author and I are describing different things when we use the term unikernel, which is surprising because we both have experience with the same unikernel: QNX. I'm not very familiar with the other examples, but my QNX application definitely does have processes that I can see using top, htop, etc., and interfaces with system hardware using the QNX system calls; all things the article describes as not being features of unikernels.

Either the article is written in the context of writing kernel software, which wouldn't have much of an impact on my decision to run my application on a unikernel OS or not, or QNX is a far outlier from other unikernel OS's and that's why I'm so confused.

ccostes··on Requiem for a Trijet Masterpiece – The Lockheed L-1011
Is anybody else amazed that this was able to do a completely automated flight in 1972? Compared to our reliance on modern computing, it's astonishing what people were able to accomplish figuring everything out manually.

Granted, it blows my mind that we went to the moon in an era where a calculator weighed 20lbs and was the size of a briefcase, so maybe growing up with computers makes it hard to imagine life without them.

ccostes··on My favorite interview question
Is such a 'probationary period' a common thing? Seems like it would be very inefficient since the majority of the hiring cost is up-front.

As a candidate, I would be attracted to an offer from a company saying 'we like you, you're hired!' much more than one saying 'you can have this job for now, but we might take it away in 3 months if we don't like you.'

ccostes··on My favorite interview question
I don't think the author meant that you needed to be 100% proficient at the job on day one. As in his example the goal is to avoid answers like 'CEO of Google'

At least, if I was asking the question, I would be encouraged that you want to expand your skill set.
