So does discrete space and time also solve zenos paradox? (or was that already solved classically?)
I just love the way this guy writes. His book, Data Smart, is hands down the most approachable intro to data science you could ever possibly read if you don't have the sufficient math background to dive into full on textbooks. And it's hilarious too.
This has been my experience as well. I am attracted to bringing games into the learning environment because they can offer unique opportunities for action/reaction/reflection (in addition to other benefits) - but I am indeed more interested in complicated decision making rather than simply choosing Red Team v. Blue Team.

For instance, I would love to see a game like "Papers Please" with a stronger element of consequences. Rather than simply being told you allowed a terrorist through the gates (with a brief cut-away) the consequences of this action (deaths, social destabilization, etc.) would impact the future game play. Perhaps, you decide to actively aid and abet these terrorists (by communicating to them that you will allow them and their compatriots to pass through) - but then you put yourself and your loved ones at risk, as well as increase social instability.

This is already a wonderful game, but I would like to see the premise taken even farther. Games could be a wonderful place to consider and critique decision making and moral choices that are analogous to those we face in real life (even if filtered through clearly fictitious events/circumstances).
> a billiard ball entering a wormhole that leads to a closed time-like curve must always meet its older self coming out of the wormhole. What’s more, the resulting collision always prevents the ball entering the wormhole in the first place. In other words, the billiard ball would simply bounce off the entrance to a closed time-like curve.

I thought what Kip Thorne proved is that you can always find an "exit" angle such that the ball that travels back in time glances its previous self, knocking it into the wormhole at an angle that will produce that exit angle. The contradiction only happens if you assume the ball goes straight into the wormhole and then calculate that it will glance itself and not go straight into the wormhole. But there is always a consistent solution as well. Though as I recall there are or can be multiple (infinitely many?) solutions and no clear way to favor one over another.

I was downvoted into oblivion back during that debacle for suggesting there were more possible viewpoints than "fire him" and "don't fire him." Everyone assumed I was from the "fire him" camp because I had a problem with his views (as expressed through his donation).

HN has that well-understood problem where intelligent people think they're immune to faulty judgement, so they end up being easy to manipulate with simplistic but pleasant-sounding arguments. I happen to agree that progressive (i.e: self-described as intelligent and open-minded) people tend to be hypocritical and easy to manipulate, but I'm obviously coming away from that with different ideas than the people upthread.
Thank you! I was looking for that option while writing the section on throwaway keys. I'll have to test it out.
Hm, not the feeling I got. Scandinavian countries (and Cypriots but that's a special case) are way more fluent in English with a way better accent (better == clearer) than Germans I've met. And I've met a lot of both actually.
I am a WIT. an actual, technical woman in tech, annoyed with myself for letting Newsweek basically troll me. I've noticed the MSM has "discovered" SV, and is doing the usual pieces (sexism! drugs! too much money!, etc.). While there are obviously so many problems in SV, they never seem to find any of the many, many, many (shudder! older) technical women at Google, FB, Intel, etc. to talk with. Everything is written through the more attractive, yet limited, prism of "young person asking for money, bad behavior ensues". I will not comment on the hypocrisy of bemoaning the limited access of women to the spotlight while turning to a self-styled male "expert" on WIT - it's easier to do that than track down actual women in SV to interview directly. I didn't feel represented by the article, I thought it was pretty opportunistic and to be honest, I don't think Newsweek cares for the "plight of women in SV", just about trying to become relevant again. And here I am, talking about it, so they were successful in their trolling.
What's make me curious - do you plan enable option for selling apps? As a developer I would be more than happy to allow user install my app, but since I am not charity I would like to earn some money on it as well.
You should read some of the other comments here. A lot of us have spent half a decade enjoying the massive improvements brought by the ribbon, and it's quite surprising there are still a few, er, very late adopters.
I left an agency job for a startup and got ~double the pay. Also, the work is WAY more rewarding. I don't even feel the need to work on side projects at home every night anymore...
I had a first generation 5150, as well, and loved it. Though when I down-sized it was the 5150 that got sold (while I kept the JCM 800). But, that was primarily a function of the size of the 5150 + 4x12" cabinet, while the JCM 800 was a 2x12" combo (which is clearly the ideal amp size for performance, though too big for recording); both amps were excellent. I consider it one of Peavey's crowning achievements, maybe the best thing they ever made. I haven't heard any of the new generation of them, once they stopped calling them 5150. They also moved most of their manufacturing out of the United States a few years back, which reportedly impacted quality...I don't know if the tube amps are still made in the US, or not.

Since I moved out of the motorhome (the reason I sold my JCM 800 and downsized to a tiny Vox was because I was living in ~200 square feet for four years, while traveling full-time), I've since bought another Marshall. It's a 50W JCM 2000 (I think...maybe 900) that I picked up for $600 (and a 4x12 cab that was a few hundred more), but it rarely gets used. The Vox sounds great and is right-sized for indoor use.

I'm really happy with my Vox, honestly; for most things it sounds as good as any amp I've ever owned, and I've owned some good as hell amps (I've also had some old Fenders). I wish it had a bigger speaker; a 10" would make it the perfect amp. It's got an 8", and sometimes low end stuff sounds pinched.
Good point. Too bad they don't offer a tenkeyless model.
You can use PM2 pretty easy https://github.com/Unitech/pm2
If we don't explicitly define some terms first, we're just going to continue to equivocate. Sex and gender are two different things that you are conflating, and masculine, feminine, male, and female describe separate things.

Sex is purely genitalia. The two extremes are male and female, but this is a spectrum and not a binary.

Gender is all the other shit that society piles on top of that. The two extremes in western culture are masculine and feminine, but this is a spectrum and not a binary. That this mostly lines up with the sexual spectrum is an arbitrary decision by society; society could define gender in such a way that it is orthogonal to sex. Examples of where gender doesn't line up with sex in western society include butch within the lgbtq community: http://en.wikipedia.org/wiki/Butch_and_femme. Other societies have in fact defined gender in a way that doesn't line up with sex, so this isn't just theoretical: http://en.wikipedia.org/wiki/Gender_identity#Non-Western_gen....

In the thought experiment he is not being rejected because of his sex. He is being rejected because of the gender he presents is not sufficiently masculine enough.
As the topic was about investments, in the context the best means whichever makes more money I guess.
You are right, I have no data to back that up.
Startups are great experience. If you are lucky enough to be a technical co-founder then you get to pick the platform, design the system and generally call all the shots on the tech side. That alone can be quite rewarding. I'd say that was the most compelling reason for me personally.

There are a whole litany of standard answers to that question such as greater risk = great reward potential, the ability to choose and work on something you are truly interested in and/or passionate about.

I feel like the reasons are somewhat obvious as most HN'ers are aware of the pros/cons of this choice though I encourage others to chime in, I'm sure I'm forgetting a bunch.

Google Earth and Maps seem to be running into each other's domains. What Google should do is update Google Earth and rebrand it as Maps or vice verse and merge the two.
Ask HN: How do you estimate cost of working on a legacy project?
I have been asked to evaluate an existing system written in Vanilla PHP. The current system is working as per client request but since code is not maintainable thus it needs to be changed. I have also been asked to use some MVC framework for the purpose.

I have existing source code which is literally horrible and painful for eyes. I am not sure whether I learn system by looking into code or go thru the site.

I would like to learn from community that how do you tackle such systems and how do you estimate? Should it be hourly or fixed rates?

Thankyou

In January I posted a project where this year I have committed to launching one side project a month as a way to get over my block of 90% finished projects...

Month one is complete and launched. These are not intended to be revenue streams or even portfolio pieces, just getting used to "finishing" a project without external pressures.

One of the odd personality changes that I've noticed in myself after 25-ish years on the Internet is that I now have essentially zero tolerance for whinges[1] of the form: "This one thing he said is completely and utterly wrong, therefore he is a pillock and should be shanked with a shiv.[2] (Well yes, the rest of what he said is perfectly true. But still.)"

Elizabeth Bear's primary complaint seems to be "Andersen is shooting so fast that he doesn't have time for a full draw." This is true. It is the first thing you notice about Andersen's video, after the fact that he's jumping around like a loon. (The fact that he's hitting targets while doing so is a little impressive, isn't it?) She has other complaints about his technique, and about the "viral" video, most of which are also true.

But what makes this rant a spectacular example of what sets off my own particular crab-osity is:

"His tactics, though--speed shooting and so forth--are suited to a shorter recurve [...], which is designed to be shot in motion and from horseback."

...like (although not identical to) the one he's using in the video. So...did she just admit that somewhere between a third and a half of her words are irrelevant to her topic?

Anyway, my bottom line is that I'd rather read a "...Considered Harmful" paper.

[1] A lovely term that I picked up long ago, from the Internet. Oddly, I can remember a significantly isomorphic rant about its use from long ago.

> the researchers have a lot of experience performing such measurements

If that is the case I'd hate to see their work in an area where they aren't experienced. Their experiment is amateurish in the extreme, and if an undergrad designed a "measurement" of the kind they performed and "calibrated" it at a fraction of the full power I would fail them.

The quality of the work is cartoonishly bad, to the extent that it would have been less work to do a better job.
You're cynical. The tone of the open letter is nothing compared to the tone of your comment. If you truely believe that we Europeans aren't living in a democracy anymore and that politics shouldn't be about the peoples wellbeing in the first place then stop worrying about PEGIDA or Dschungelcamp and do something about that. You stance of "this is how the world works and I'm lucky to be on the winning team" is both short sighted and highly egoistic. I would be ashamed if many of our "fellow germans" would agree with your point of view.
For an A-list game this is probably true, but there are very many indie/small games being developed which use 'archaic' game mechanics/stylistics.

I'm actually surprised to see the visual and mechanical simplicity of many games that have flared up in popularity among my students. Certainly, the processing limits of mobile phones play a role - but that doesn't stop these small games from passing through the student body like wildfire (and then burning out equally quickly).
I find it the opposite, and I played in high school too, but since I know the mechanics of everything it makes it a lot more interesting. For instance most people only get the gist of the game, whereas for me actually seeing what formations the offense is running and what coverage scheme the defense is using on a particular play makes it 100x more interesting than if I didn't know any of that stuff like the average viewer.
>Staying in Cleveland depends on if you like Cleveland or not.

This. I have no experience myself living in Cleveland, so I have no opinion on it, but from the outside it doesn't seem to have a lot to recommend it. In fact it's sometimes used as an example of a generic city. [1]

BUT if you [OP] have a strong network of friends there, that alone could be reason to stay.

If you're at all considering starting something new instead of just looking for another job, there are advantages to staying away from the coasts. With Google and others offering developers $200k+/year in compensation, it's hard to find good people to work with -- and you'd be farther from your network if it's primarily located in Cleveland.

But look at your network and figure out where it's concentrated. If you do know a lot of people in another location, it's a prime opportunity to move there.

And if you are looking for a new job, the coasts are great for that. I know I could have my choice of job if I were willing to work on the coasts. I'm in the Boulder area now, though, and I'm not leaving -- though I'm working remotely for a company on the coasts. [2]

For me, I decided to move to Boulder because Boulder is awesome. I grew up in California, but hated the congestion and insane housing market. The K-12 schooling system left a lot to be desired as well (again, if you're looking at kids as an eventuality).

But Boulder was partly an attraction because I have family here; take your own situation into account and figure out what you want. There is a lot of tech in the Boulder/Denver area, so that's one option, but there are fewer big companies offering crazy salaries (Google has a Boulder office, but it's not nearly as huge of a presence here).

Good luck!

The article is claiming that the guy can predict which things are going to succeed and which are going to fail, not make them succeed or fail. His evidence for this is that 50% of the time, he's right (e.g. [success, success], [fail, fail] are both success conditions for him). For him to be adding any information to the system, he has to get it right more often than either choosing randomly or using a fixed zero-information strategy (always bet fail/always bet succeed). You explicitly said that the joint probability matters, but then miscalculated the joint probability of him guessing correctly by random chance.

I think you may be mistaking my comment with another. I am not (currently) a teacher (though I do very much like explaining things!).
That's not independent verification; it's not even vaguely close to independent verification.

"Even if Rossi did some screwy stuff, it cannot explain the 1.5 MWh gain for more than 32 days"

Sure, he could have literally hacked the instruments. But, 1.5 MWh over 32 days is a fairly small amount of energy as in 2kW * 32 days a lot of chemical processes can get you there. Also, measuring heat output is really easy to mess up. Something as simple as putting an insulating blanket under the device could significantly alter the measurements. The point is he was there when they were setting up the experiment so he could have easily lead them astray.

PS: As to warrants further research nope, sorry the correct response is to declare this a clear scam.
I'm not a huge sports fan. I go to a couple baseball games a year, but I no longer watch any of the games on tv. I only watch the Super Bowl for the ads. The morning radio show I listen to is technically a "sports" show. It's pretty light on the actual sports and is mostly just stupidity, which I prefer in the morning (on the way home it's mostly NPR or music).

Anyways, I glean enough sports info from the show to hold conversations with people who are really into sports. Being able to socialize with all types of people is a good trait to have.
I believe it means setting up an opportunity to evaluate the skills of the professional inquiring about the job.

I think they found out in-depth longread type articles don't guarantee a consistent readership. It's possible to pull off if it's a once a week or twice a week kind of thing, but they were trying to do it as their main content source.
To add to this, figure out insurance and freelance taxes. Those two nearly came back to bite me when I first went independent.
Thanks. I definitely want to implement more of those parts as I go. I just got a bug in me about making this one earlier this month and started pushing it through. Now that I have this, my next project will probably be a small, AI-programming game, ala CRobots or something.
> I have looked into doing freelance work, but as I am self taught my CS skills are not as solid as other developers, and my design skills are just about average

Skills have very little baring on success as a freelancer. 99.99% of clients will not care what language, framework, algorithm or pattern you use to create their product.

The biggest issue as a freelancer is clients. Clients are absolute hell.

How it shows up depends on the model. Superstrings are objects of (usually) Planckian size, so if the particles are the size of the "grain" then that is one way a scale could manifest.

In other models like loops quantum gravity you can only ask questions about loops in space and not about points so that is another way the scale manigests.

I really enjoyed reading this.

I had a relatively blue collar american upbringing, but more or less since the day I left for college I've been predominately surrounded by people from white collar lifestyles, and this article really resonated with me.

As illustrated in the article, the difference between the cab driver and the highly educated professional taking the cab is not as great as the latter would often like you to believe it is. Life is a lot easier when you stop pretending that things like sports or certain types of music are "below you".
Ask HN: How do you price an indie game?
Hi HN!
I'm planning on releasing the game I have been developing in my own spare time for a while....it's still not finished,but I would like to have a general idea how other people approach this problem - how does one price their app for sale? I would like to do a simultaneous Play Store+App Store release, and would like the app to have a free demo version that can be upgraded to full for a fee + a paid full version. But then.....I honestly don't know how to approach the matter of price. Should I go for the lowest possible price or price it at 2/3/4/10+ dollars? I think my question is - is there some good process to follow in order to determine the price, so I could actually arrive at a "researched" number, rather than go with my gut feeling? Any help would be appreciated :-)
Ah ok, thank you. If I understood correctly, you take "occupy a strong position in the social order" to mean a group's strong enfranchisement and entrenchement, up to the point of closure within the political culture (in the Almond-Verba technical sense of the term).

My only quibble with treating "welfare recipients" as a group is it conflates two quite heterogeneous groups of people: seniors/retirees in one hand, and disabled people plus medicaid/food aid/SCHIP recipients on the other. The former do account for the majority of welfare spending and quite justifiably fit (my understanding of) your definition of "strong position in the social order" in the sense of strong enfranchisement; but the latter hardly do.

On the surface, it means SSH tried, and failed, to initiate an interactive session. In context, it means that either the developer has disabled new users, or this is simply broken at the moment.
What's wrong with footnotes?
Hmm, I think the reason this app seems weird is because it's tricking the user at the other end when what she wants to see is her SO more engaged. I can see this app as actually being useful if it merely serves as a prompt to have a short conversation at reasonable intervals if you haven't texted in the last day or two.
Timely. I did a "big data" presentation yesterday and hoped to convey how important it was to read original source materials to form opinions and avoid the hype.

Since slide decks get busy I moved my bibliography of links to a gist. So, while it didn't factor into my presentation I've now added this blog post. :-)

Your question, actually, is self-contradictory. "Where" already assumes space.
And what happens to the fact that the data has changed if the client becomes disconnected for whatever reason? Is the fact that the data has changed committed with the data atomically. Is the query persistent across connections? Or does it end in tears?
I think it qualifies for brief definition of brief.
