> I'll warn you that it's very 80's hackeresque, but in a good way. Incredibly pragmatic.

I consider the BEAM VM as one of the marvels of software engineering.

You know it is good, when you explain to other programmers that you can have something like an isolated memory process just like an OS process, with preemption and only a few Ks of memory, with a low latency GC, with distribution across machines built in -- and they don't believe me.

Even experienced senior developers are skeptical saying stuff like "well yeah but those are green threads then and they have to yield explicitly -- nope, they don't", "so you have callbacks then somehow, no, not callbacks", "what do you mean separate memory spaces, it is a single OS process right?" and so on. It sounds like magic -- this stuff shouldn't exist, right, but the awesome thing is, it does.

Moreover, it is not a hacked up version from a lab some place or a PhD disertation proof of concept -- this is what powers banking, databases, messaging, and probably more than 50% of smartphone access to the internet today.
For all these people complaining about San Francisco housing costs, I say: just go somewhere else. Nobody is forcing you to work or live there. By crowding in there you are just making it miserable for those already there.
An interesting tangent that I expected someone to bring up but not applicable to the scenario I illustrated:

There's an api, and the pricing isn't cheap, but I feel like this is going to bring a whole new wave of spam after the initially scraped list gets resold over and over.

You might have an additional revenue stream selling an "opt my email out of this thing" plan.
Because sometimes they excuse themselves after leaving you with the test script. Some don't bother sitting through with you the entire session, especially if he or she is just a HR personnel and is simply tasked to administer the test.
I'm curious: what are the advantages of having your access layer rely on column indices rather than column names?
You require a staff of 200 before you allow titles like 'Senior'? Ouch.
Well written, thanks. There was a time when the ACA was about a single payer healthcare system. Wouldn't that better explain the red scare accusations of socialism?
I just bought myself a motor cycle a week or two back which runs just fine with a completely dead battery (I need to roll start it, but its a 125cc two stroke so that's _super_ easy...). The indicators don't blink with the dead battery (they just sort of light up), and the headlights are very dim, but it ran just fine for ~450km like that last Sunday...
Given how psychological experiments work, what's more likely - that you have a higher IQ than everyone else involved in the program, or that one of the things they're studying is the effect of believing you have a higher IQ than everyone else involved in the program?
Most drivers or interfaces to the db let you use the column's name instead of the ordinal positions, precisely because that decouples the query's result from the things you care about, might be worth checking ^^
Well, cars whose computers are not linked to a network.
Hey dude, follow the thread: I'm defending someone from a bunch of bullies.

I'm not repeating those behaviors at all. I'm just calling a spade a spade.

You seem to think that someone who picks a fight with a bully is somehow guilty of also being a bully.

All you end up doing is passive-aggressively condoning their bullshit behavior in the first place.

I'm guilty of being nothing more than a fed up son of a bitch with a rude attitude. I can live with that.

You're morally bankrupt. Can you live with that?
My understanding is there is no fee when putting in money towards your Vanguard Index Fund. I don't think they charge any extra money per transaction. You probably get screwed a little based on how quickly prices update and what price you pay per share (I don't know if you do but I'm just guessing). However, as people who don't have a day job in buying and selling financial instruments, I think we are probably better off buying and holding. And hoping and praying the US economy and the world economy will overall grow in the next fifty or so years.

Friend of mine work over at WealthSimple. Glad to hear people like it.
What did your gut tell you? You said it was a great startup but what was vibe from hiring manager? I'm willing to bet you didn't feel excellent about him or her.

Its the best tool. I had a certain feeling about my curemt boss (like this, don't like this) and its right on the money 4 months later. Just get a sense from what they focus on (and what they gloss over), how they talk, their body language, and more.

Next time ask how excited you are to join that person's team

Running this is amusing:

Personally, I'm partial to running IPython under Sandstorm for this kind of thing. (Also, if I were to host it, I'd be very nervous about any technique not involving equal or greater paranoia.)

> If React didn't have an explicit "grant" there would be an implicit grant.

Please provide a citation to any court decision so holding, or to the text of any law that clearly implies this.

The reality is that a couple of lawyers have come up with the speculative theory that maybe, some day, a court will read the plain text of the BSD license as granting an implicit patent license because some of the words its uses are kind of similar to the words used in a seemingly unrelated law.

This theory is...tenuous at best. More to the point, it's just a theory about what a hypothetical court might rule one day in a hypothetical case. (Plus, I mean, hypothetically the court might rule that an explicit grant can't limit the rights granted by an implicit grant in this case. Since we're just speculating about what new rules a future court might hypothetically make.)

And "many people" write code by dragging squares around in a GUI and entering equations into spreadsheets, but that method is completely unacceptable to a professional.

The only people who write math in a drawing program are people who don't do enough math to be bothered to learn it.
Yeah, every programmer at one point has to make her own argument parsing library. Nope, there is no one syntax that fits all use cases.

While there are thousands of ways programs can parse arguments (and that's great!) there is only one argument passing mechanism in Unix (plus environment variables for implicit static things and file descriptors for streams).

Unix doesn't care how you parse your arguments, and that's why it is lean, and why it has been successful as a development platform.

Donald Knuth: "I define UNIX as 30 definitions of regular expressions living under one roof."
I too am worried, but if this crisis comes to pass I will do my duty and start working for a hedge fund.
Already happening at the top end. The smart money is talking about moving elsewhere, especially after the recent tax changes.

The top end - flats worth a million and up - has a long way to fall, because there's a glut of new build coming onto the market.

The mid and lower ends have a lot more latent demand, but the end of cheap buy-to-let will force at least some landlords to sell up.

Prices would usually level off, but if sterling keeps drifting lower foreign money will dump a lot of its speculative holdings. That could crash prices by big numbers, and also drop rents because many speculative buys are currently left empty.
I'm fascinated that Carmack thinks Quake 3 is overlooked. At least among the people I know, Quake 3 is considered the best multiplayer arena shooter of all time.

> If someone (or some company) is claiming to be better than me at using my money to make money, surely they'd agree to put skin in the game, and only profit when I do?

Imagine you believe that mail order companies are poised for rapid growth in coming years. You don't know which ones specifically, and there are thousands. So you buy a mutual fund which holds hundreds of these companies. This gives you some diversification and lets you make your bet with only a single commission to buy and sell.

But the fund manager may disagree with your investment thesis. She may be fully convinced that online shopping has already destroyed the mail order business permanently. She would therefore gladly run a fund for you, but she would not bet on its performance herself.

For a somewhat more real-life example of this, watch or read "The Big Short." The protagonist wants to buy something that the banks think will lose money.
It's a contested claim. However, here's the first document and reference on the C language:

https://www.bell-labs.com/usr/dmr/www/cman.pdf

Show me where it references BCPL. As I see it, Ritchie only references B as the inspiration for C. From the document, anyone who hadn't read the B paper (most people) would think they, Thompson, and/or Ritchie mostly came up with C's features and strengths. They eventually became known as the "C philosophy" and C-like languages.

Whereas, it was Martin Richards that invented both of those plus the idea of stripped down languages for writing tools on minimal hardware. He should get credit for creating the "BCPL philosophy" that the "programmer is in control" plus inspiring a BCPL-like language called C that allowed UNIX's success. Instead, early work focused all attention on Thompson and Ritchie with UNIX papers/software making sure that was the case by adding momentum.

At least I got to see the guy in action in the video linked to my History of C page. It shows his team, the constraints they worked on, why they dumped most of ALGOL, and him working with it later on. That presentation put things into an honest perspective where I can see his and UNIX founders' contributions to overall success with due credits (and/or critiques) to each.
I'd argue that it's not exactly in the spirit, but definitely worthy of discussion.

> The Democrat congress and President would have been able to hold the majority if they had not stirred up the hornet's nest of populism from the right through the healthcare act fiasco.

Yeah. The Democrats stirred up populism from the Right by enacting a policy solution that closely followed health care policy solutions supported at one time by the Heritage Foundation and the 2012 Republican Presidential Candidate.

That's how we got here.

Plus nakedly uncompromising partisan power grabs like Obama's nomination of Merrick Garland.
Exactly, which is why I am pointing it out so that the post does not get killed on a technicality.
How much tax benefit do you get from deducting your home office? Are you a contract employee? I've run the numbers every year, and I generally don't have enough deductions to justify going through the work.
The vast majority of the data sets are very small (on the order of 100 to 1000 examples!). In fact, in the paper they discarded some of the larger UCI datasets.

It's not surprising that they found random forests perform better, even though the conventional wisdom is boosting outperforms (it's much harder to overfit with forests).
Why did they implement the "blink your LED" function as a web service that passes its input directly to `system()`?

This kind of argument seems to ignore the idea of federalism and limits on federal power. Just because something might be a good idea for one state doesn't mean that it's a good idea (or constitutional) at a federal level.
I think that rather strengthens the argument that Facebook's patent grant isn't a good reason to avoid React, given that almost any possible webapp written with any framework is likely infringing. :)
This wasn't a locking issue.
Yes, one way that the poisson process is defined is as a counting process with inter arrival times that are iid exponentials.

The poisson process is the first (continuous time) point process discussed in many textbooks because the counting increments are identically distributed, since the rate parameter is a constant. You can think that in the case of modeling waiting times for subway trains, a better model is with the rate parameter that is dependent on time, since the inter arrival times are smaller during rush hour than when the subway is closed.

You can read about this in Bertsekas, and more thoroughly in Parzen or Cox's books on stochastic processes.
Hi, this is Leo, Optimizely's statistician. If you're looking for a more scientific paper, maybe take a look at this one we wrote recently: http://arxiv.org/abs/1512.04922

Should have everything you would ever want to know about the method.

I agree with you that the problem of inference and interpretation between A/B data, algorithms, and the people who make decisions from them is a hard one and worth working on.

That said, I do think the two sources of error our stats engine addresses - repeatedly checking results, and cherry picking from many metrics and variations - did make progress in having folks correctly interpret A/B Tests. This did result in more conservative results, but the benefit was that the variations that do become significant are more trustworthy. I think this was absolutely the right tradeoff to make for our customers, and trustworthyness is a pretty important aspiration for stats/ML/data science in general.

Of course I did write the thing, so I'm not very impartial.
It moves into the price discovery mechanism of the market. More people in passive funds => fewer people doing active research on companies => greater likelihood that the market price of a security doesn't reflect the underlying fundamentals of the business => arbitrage opportunities for active traders, as chollida1 pointed out.

People will still get phenomenally rich in the stock market, wealth inequality will still increase. The difference is that people have to work for it now, building up their own information advantage, rather than being able to siphon off large fees simply because they went to a good school and talked a fellow alum into hiring them. This is a plus in my book.

It's not flawed at all. You can always go back to college if you want.

If you don't want to go back to college (because you don't judge it to be worth taking time off your career for)... yes, I suppose that will make going back to college rather difficult ;)
Man made food IMO is the victim of .. men. As soon as we could cook and eat for pleasure we optimized for it. This era is just going too far (lots of industrialized food is scrapes coated in sweetener and whatever to make it tongue friendly). I can't help but to think it's all a consequence to our desires and lifestyles. We have more time to do nothing so we do them to tickle pleasure centers. Everything is unbalanced, you don't walk or run to catch food, you sit, and so you don't care about getting nutrient but satisfying the needs for thrill. Loop.
> And actor supervision is the best way to write reliable systems.

Need some citation there, because we've been writing extremely reliable systems (multiple nines) for decades in various languages (mostly C, C++ and Java).

All these languages (including Erlang) come with pros and cons to write such systems, but so far, Erlang has failed to deliver on most of the promises that its advocates repeatedly make.

Apply HN: Patron – Uber for the Service Industry
Patron- patronapp.org Get Sh*t Done

I often find myself not having time to complete chores such as shopping and cleaning. Along with this I found it incredibly costly to hire a maid or caretaker therefore I founded Patron, an app that allows people to post tasks and set their own prices. Well who does the work? I'm doing what no other similar service on the market does, anyone can download the app and complete tasks to earn money. I am hoping to build Patron to be the Uber of the service industry where anyone can be their own boss and work on their own schedule.

Right now, I got a completely working application and am focusing on polishing it for publication.

How (are you going to make money): We take 10% of the total post cost.

Where (are the competitors): UberEats and Taskrabbit are our closest competitors. They all have the issue of quick expansion as they have an actual employee system.

Given that they were seeing if a precondition is true (arrhythmia started within last 48 hours), and the data showed that there was a significant change over time, it seems somewhat reasonable to act on if the patient wasn't totally sure.

Physicians usually want to know what is different or regular for the specific patient over time, whether or not a value seems high for one person doesn't mean that action needs to be taken--but when that value changes significantly or shows a trend in a particular direction over time, that is information relevant to what procedure they decide next.

It is entirely possible that the fitbit started recording data differently at or after the seizure, supposing it got shifted in the event. However, that does not invalidate the trend of the data as a whole. In this case, the patient was seemingly able to help acquire such data. If the patient said they were one way or the other, or if the patient depended on a device to fulfill that judgement, is it really the physician's fault to choose what the patient provides? IANAL
Bcrypt has built-in salts to prevent rainbow (i.e. lookup) table attacks. More to the point, modern password cracking doesn't usually involve the use of rainbow tables anyway. GPU speed has improved at such a rate that it's actually more practical to just compute all possible hashes from plaintexts (in a word list) to find a match rather than performing a lookup against a rainbow table that might have to be terabytes in size to be useful.

Essentially, if you ever find yourself having to think about manually creating and incorporating salts into your password hashing mechanism, it's a telltale sign that you are using an unsuitable password hashing algorithm to begin with. Instead, you should almost always be using bcrypt, scrypt or PBKDF2 as per current best practice.

I'm a life long Californian. I dislike Prop 13 and it's evil sister Prop 58 which allows children to inherit their parents property tax break along with the property. AKA my dad has a house with an assessed property tax value of about $75k, when he dies and my sister inherits it, she'll also inherit the $75k property tax valuation as well.

That said I don't think the current issues with housing in the bay area have much to do with Prop 13. It's why your schools suck. It's why the prices are high, because the carrying cost is 1% lower than you'd expect because property taxes are too low.

Real issue is the deranged FIRE based economy we have. FIRE Finance, Insurance, REal estate. Combined with low growth and income inequality. Means you have a lot of money pouring into 'hot markets' like SF, Boston, Vancouver etc. Same time there is collusion between the people that sit on the boards of large companies to suppress wages.
Well, maybe not if you're jumping to a new platform, API, framework, language, or library each time you start a project.

Browsers, Innovators Dilemma, and Project Tofino
I don't want to look at it in any particular way.

I was asking for clarification, to see whether I understand the features correctly, and to determine what customers get by using your product.

So the question remains: what does the customer get beyond using, say, Mongo? You say it's a relational database, but the Schema-On-Need feature sounds awfully NoSQLish. What's the point of using a fixed schema at all if it simply creates new fields on demand whenever you try to insert a nonexistent field? Why not just use Mongo in that case?

Having a new query language that some people like is nice, but how do you plan to build a company around that?

Why is it different or better than the hundreds of other query languages out there?

Such a pity that “Show HN” got bumped
"Show HN" used to be the heart and soul of Hacker News.

Hackers and startups would make stuff and show it and the community would comment.

There's now at least two layers of distance of Show HN from the front page. First, new Show HN'S go to some far off land called "Show newest" https://news.ycombinator.com/shownew and then through some magic they might end up on "show" https://news.ycombinator.com/show.

I rarely make the effort to click to find Show HN's. They may as well be non-existent. As for "Show newest", well never.

HN is a lesser community for having relegated Show HN.
I would much rather work with a team of people of average intelligence, with humility, work ethic, honest enthusiasm, empathy, etc., than with a team of brilliant people with none of those things. That goes double for technical jobs where you're building a complicated product over the long term. We're not here to solve the Putnam and go home. We're delivering value, and that involves solving a hard problem simply because there is no easier way, not because hard problems are inherently worth working on.
@dandermotj I understand that, just included the reason why you cannot get it. The online book really sucks. I turned the styling off.
I find that this is interesting to compare with Pulse-Width Modulation[0], in which a system must alternate between OFF and ON at some proportion to "simulate" a non-binary signal (i.e. 60% of the time if the signal is on ON and 40% it's on OFF, then it looks like, on average, 0.6 rather than the discrete 1.0 and 0.0).
