show hn: flight search on steroids: find better flights through machine learning
| cool ui, tried it on my recent flight, but for my case i could find better deal on orbitz.example: waw -> sfo (july 18, aug 2)imo best: waw -> ams -> sfo (14h25m), sfo -> cdg -> waw (14h5m) 1256$your flights are a bit cheaper, but the shortest available outbound is 18h40m.maybe you can tweak your algorithm to optimize for shortest flight for people willing to pay 5-10% more if that saves several hours. | i know naming startups and getting domains is hard, but delta is the 2nd largest airline in the world [1]. naming your air travel site tripdelta seems likely to raise some significant trademark issues.[1] <link>'s_largest_airlines |

atlas general availability
| for any of us who have watched this team's output and quality and wondered _why isn't this team being acquired?_, here is hashicorp's play. congrats to team on shipping.
it will be interesting to see how all this plays out. | i've never used any of hashicorps stuff (thought consul did arrive on my radar theother day..). any recommendations? we use the atlassian stack here (stash, bamboo, etc) and deploy to aws (regular amis rather than any of that fancy docker stuff). anything here we should look into? |

china tries japan's approach to a stock bubble
| the similarity between china now and japan 1990 is very noticeable. that is, they're both exporting country that has an aging demographic which likes to save, has a small consumer base compared to export, and is losing export shares as production moves out of country to other cheaper countries. and they both choose to save the banking system instead of letting it self correct. this means that china will likely see 10-20 years of deflationary decline just like japan. however, because china suffers from massive capital outflow from rich leaving the country, and it already has reached very high debt to gdp ratio (something japan reached only years later after 1990), i would say china is in even worse shape than japan in 1990. | let's get real about the china stock market "crash" -- all major china stock indices are still up between 30% - 70% from 12 months ago. somehow the run-up in prices was business as usual, but the slide down is a catastrophe. a real crash has much further down to go.

united airlines system-wide computer problem
| nice reminder about a "glitch" happening in one of the datacenters use at the airline i used to work.went like this: guy who shows around the new datacenter/ops guy demonstrated how the emergency power off works by lifting the protection plate. protection plate unhinges suddenly and droppes onto emergency power off button. hilarity ensues. | i bet this is an issue with an old mainframe used somewhere in the booking system, something that has worked well but is difficult to fix when things go wrong.i think there is / will be a lot of money to be made trying to solve the problem of software security and reliability. this is obviously an extremely difficult problem, however the number of ancient systems that we currently have interconnected i think more large scale outages like this are inevitable. |

why we sleep
| this is where f.lux - <link> - is so great. after sunset in your location it gradually bleeds blue light from your display: also at work i use it to just orange-ify the display a bit at a constant rate - because work is lit by fluorescents - and on a bright monitor it noticeably reduces eyestrain. | tldr:when we sleep, our brains process the events of the day and pick out things to stow away in our long term memory.maybe as a side-effect of this processing, they also aid problem solving - after a good night's sleep, you are able to find solutions to the previous day's problems faster (than you would, if you hadn't had the sleep).as we sleep, our brains clear away toxins that accumulate during our awake time. these toxins may be culprits behind neuro degenerative diseases.there seems to be a correlation between sleep deprivation and cardiovascular diseases. |

ruby is defined by terrible tools
| hmm, i'm not so sure about this.ruby's tooling is obviously not as advanced as a language like java, for many reasons. but terrible isn't the adjective i'd use. it's pretty easy to use editor integration to provide pretty decent automatic formatting, linting and code completion. pry-debugger is pretty great, and generally i don't find working in ruby to be markedly more taxing that other languages.i guess ymmv, though. | i tend to think that the sophistication of the tools reflect the extent that the language is broken. valgrind doesn't need to exist for the java user. you don't need class boilerplate getter/setter generators for scala. nobody needs npe static analyzers for rust. the need for rename refactoring tools is drastically diminished by the existence of type inference, almost to the point where `:%s/foo/bar/g` is entirely adequate.the non-existence of tools that you find in other languages might signal an immature ecosystem, but it might also signal a diminished need for them. |

show hn: potbox – a premium cannabis subscription club
| anyone interested in the subject must read the us supreme court case gonzales v. raich to understand the serious and weird risks involved.raich was a terminally ill old lady, living in ca, who in compliance with state law and under her doctor's oversight, was growing 6 pot plants for her personal medical use. she was subjected to a federal dea (drug enforcement agency) home-invasion raid wherein said plants were seized.raich argued the legality of growing the plants for personal medical use under state law, intra-state, alleging doing so in no way affected interstate commerce and thus was not subject to federal regulation & seizure (and violently so at that).the court ruled that her growing her own pot for personal use did affect interstate commerce by reducing demand in an illegal interstate market.no, i'm not kidding. yes, they said that.while the current federal administration may be opting for leniency in enforcing controlled substance laws, the next (1.5 years away, whichever party) may choose to resume aggressive enforcement to the limits of the law which scotus has defined, which as raich shows is very, very expansive. i suspect a, say, premium cannabis subscription club might be first on the dea hit list.[ps: the ruling in raich may have been affected by the pending stewart case, which was remanded in light of raich. if raich had been ruled to the reverse, stewart would have in likewise reasoning legalized convicted felons building machineguns at home (legal under washington state law). i'm not kidding about that either.] | how will they ship this? it is probably a big crime to commercially mail pot across state lines that have not legalized and decriminalized it. |

beware of “async void” in c#
| async void methods are for asynchronous event handlers. [1] that's an unfortunate consequence of the way event handlers work in c# (event handlers that return a type don't work well in the language).any other use of async void is incorrect; if you see an async void method in any other context, replace it with async task. (would be nice if calling an async void method directly threw a compiler warning to make this completely clear.)[1] <link> | to make it perfectly clear , "async void" should be replaced with "async task"the async stuff is interesting in that akin to generics it has an almost cancerous effect on your code. when you start using them they tends to spread to large parts of your code base if you're not careful.it's awesome that c# now has such good support for parallelism and asynchronicity... but i remain in the opinion that a lot of this stuff is grafted on to the language and at some point we need to start over from scratch. already more and more of the code is taken up by crud that should be abstracted away. |

await task.delay(1000);
throw new exception("no crash here!");
}
why? a lesser known artifact from the .net 2.0 days. in an unbelievable feat of foresight microsoft wrote a class called synchronizationcontext[1]. it's a tls object that defines a way to invoke methods on a well-known target. in the case of the one provided by system.windows.forms (which is active in the ui thread) it will dispatch callbacks back onto the main thread. essentially what is happening with my above code is: void button1_click(object sender, eventargs e) {
var sc = synchronizationcontext.current;
task.delay(1000).getawaiter().oncompleted(() => sc.send(_ => {
// back on the ui thread, thanks synchronizationcontext!
throw new exception("no crash here!");
}, null));
}
the windowssynchronizationcontext object (which is what synchronizationcontext.current will point to on a ui thread) simply has a reference to the dispatcher and calls something similar to control.invoke(). this means that the code is re-routed back to the ui thread and because it occurs there you get the standard windows.forms error dialog with the option to "quit" or "continue" - ultimately preventing a crash. tpl leverages synchronizationcontext which is why this all works. indeed, the very final example in the article (it looks like windows.timer) won't crash with `async void`.as far as i remember, asp.net provides a synchronizationcontext for requests but i am unsure as to how it deals with exceptions (if it does at all). it's implementation specific.finally synchronizationcontext can be implemented by you allowing you to also deal with these exceptions in a clean/proper way[2]. please don't ever do anything along the lines of `swallowexception`. keep in mind that not everything takes advantage of synchronizationcontext (e.g. threading.timer) so it's definitely not a catch-all.[1]: <link>

| what's the business model? probably not interchange, if its debit cards. debit card interchange got regulated down to practically nothing by the durbin amendment. | i prefer using my own credit card and getting reimbursed since then i get points on my card. (which i then use to buy things on amazon that i want without considering my budget.)obviously this is part of credit card companies charging fees that hurt small businesses. but as long as the system is that way i'll use it. retailers don't charge me different fees based on which credit card i use, so i might as well use the one that gives the best rewards. |
céu: structured synchronous reactive programming
| i discovered this while struggling with c++ for an arduino project. i'm really digging ceu as an alternative that runs directly (and efficiently!) on the arduino. | i can't be the only person wondering: how do you pronounce it? kay-you/say-you? kyuh/syuh? |

céu: structured synchronous reactive programming
| naming things is hard, but this seems like a total punt. :) help us out! | one of the neat features of céu is that it has simula-like objects with coroutines. method calls are asynchronous, can be paused while they wait for events and many objects can be simulated run concurrently. one of the students here in the lab is experimenting with using céu to code the logic for some simple 2d games and according to him the event system allows you to write code in a very "natural" way.another special feature of céu is "strong abortion" with the par/or primitive. par/or lets you run two computations concurrently and if one of them completes the other one is aborted and all its resources are freed. aborting asynchronous computations is not something that all asynchronous programming systems let you do very well.(btw, if anyone is wondering, céu means sky in portuguese) |

technical hiring and cultural fit
| wonder how many glitches we see today are because everyone gets along and doesn't know how to fix the issues. sometimes disagreeable people are like that because we are tired of the stupid. ( hypothetically of course ) | how do you know that the culture you're hiring for is all that great for getting results?is this culture the one you're going to need in the future?what if you have a need, and there's nobody that fits your culture? if you're understaffed, is it really better to keep asking your staff to work extra while you satisfy the culture requirement, even if it's just while someone ramps up?lastly, "culture" seems to be another way of saying "we don't really know what works, so we just look for people we personally like".i've worked with many people i didn't like, or even got along with (i'm sure others could say the same of me). focusing on tasks and goals, communicating regularly, and having decent work habits went very far. |

in-app feedback results in fewer negative reviews
| somebody needs to tell them the secret to 80% fewer grammatical errors :)it seems their sdk makes it easier for people to submit feedback directly from the app, rather than complaining on the app store, i.e. fewer negative reviews (and maybe fewer reviews in general).one alternative i've seen used for additionally increasing the number of positive reviews is to prompt the user whether they like the app. if they say "no", they're asked to provide feedback, but only if they say "yes" are they redirected to the app store to rate the app. | i've used apptentive for this and we had even better results. we get almost no reviews below 5 stars. |

| i've used apptentive for this and we had even better results. we get almost no reviews below 5 stars. | i'm not sure you need an exterior service for this, but the concept is something that should be a definite feature for each app you build.with streaks (streaksapp.com), we ask if the user is enjoying the app. if yes, we ask for a rating/review. if not, we direct them to send feedback (email, twitter, etc).in hexiled (hexiledgame.com), we don't ask for a review/rating unless the player has successfully beaten the level, assuming they'd be feeling more positive about the game. in us and au, that's helped us get 1,000+ reviews averaging 4.5/5. we also put our names and faces in there so people realise this is a first-ever mobile game by two guys and not a big-company effort where your meagre iap will get lost in the millions made.i noticed that with highball they try to put the app in the context of "this is a free thing we have made, go easy on us" very early in the on-boarding. otherwise reviewers can be absolutely brutal and often unfair. |

really useful if they could provide more examples and supporting data
for their claims, but the claim itself is still interesting on its own. |
