I don't know about speed, but with this package you can have Haskell types at your disposal.

If you use them properly, you would not be able to compare p values of experiments directly (a common mistake).
> uses bittorrent trackers to identify the nodes in the network

It's using a distributed hash table, not trackers. Nothing's completely decentralized; distributed hash tables are pretty good, since you can join them by talking to any participating node at all.
I think you already see that younger generations don't prefer (or simply don't at all) using those social apps. Instead they use several social apps for specific things: snapchat for pics/text, whatsapp for text, vine for video, tinder/grinder for dating, instagram for social and pics, and more that I'm probably just not aware of because I'm 30. I think you're less likely to see a replacement and more likely to see them become places for "old people."
Basic Linear Algebra is useful in any GUI programming, especially games. Numerical Analysis is also generally useful.

It depends on your interests what else might be useful.
Ask HN: How to mitigate the risks of open sourcing a project?
A friend and I created a platform for organising simple and fun forecast challenge with friends / colleagues for major sporting events (www.scoragora.com). We launched for the football worldcup last year and add a decent user base (7000+ users wordwide).

The purpose of the project was to create something cool, used by a lot of people, to learn how to craft this kind of website, to experiment trendy technologies (node, grunt, angular, ...), and eventually to make a bit of money out of it (at least cover the expenses small).

I posted a link on HN at that time (https://news.ycombinator.com/item?id=7873348), and during the worldcup we received some very useful feedback from dev users, and some offers to help. It would seem very natural for me to open source the project to ease the collaboration, and avoid spoiling all this good will.

However, I would like to keep the opportunity to eventually make some money out of it. And I fear that if I open source the whole github repository, I risk someone forking my repo and making a business out of it (who said paranoid ?)... I guess that's a pretty common preoccupation when you want to open-source a project.

Now the rugby worldcup is coming in a few days and we have opened the platform again, so we will probably receive a handful of help offers (hopefully). What would you do ?
Saving Agile with BDD and Cucumber
Completely agree with this. I spent most of my youth in an extremely tired state. Up at 7 to be in school for 9. I doubt I ever really learned anything useful until after 11am. By 4pm I was shattered, then had to go home and do sports / homework until 8-9pm. At the weekend atleast at one of the days was spent sleeping in, purely because I was so unnecessarily wrecked by the stupid school hours.

Fast forward and these days, since setting up my own company, I rarely start properly working until 11am. By that time I'm not exhausted getting up and am ready to be immediately productive.

So what about adjusting to societies (stupid) rules at such an early age - most people are not morning people anyway. School is supposed to be about learning and productivity, so why are we making it part of the "hours just for the sake of it / that's how it's always been done" problem?

School hours are basically currently set as it's a form of childcare but parents are working all kinds of hours these days - why should schools be different?
I don't think this holds water at all.

The crux of the article is:

> ...one last gap remains in the middle of this stack of system exclusivity: Apple licenses the instruction set architecture for its mobile devices from ARM.

But Apple already not only designs the own SoCs independently already, they regularly add their own opcodes to the ARM instruction sets they license, as they see fit.

The alternative to not licensing from ARM, even if they "invented their own ISA", would be to pay an exorbitant sum in royalties to ARM and every other patent-holder whose technology they might dare use in their chip. So paying ARM for their technology in one go just makes the most economical/legal sense.
Show HN: WikiPop – Endangered Species Population Tracking and Crowdfunding
Thanks, I didn't really consider this part of the problem. I thought, for "gadgets" (pc, smartphones and small electronics), DRM was a limited problem (I heard about coffee machines and cat litterbox DRM, and that's it). But it may well becomes a problem, if manufacturers find that people repairing gadgets reduce their revenue, which pre-suppose a non-negligible part of potential consumers are motivated to repair instead of buying new (I am not sure it's really a lot right now).

For limited access to parts, it depends what "parts" we are talking about. If it is an electronic part (capacitor, microcontroller etc...), most gadgets use off-the-shelf components, that are easy to find, provided you know where to search. If it is a black-box with very specific requirements (screen, battery, whole PCB ..), access to parts may indeed be a problem.

While I like the political right to repair, we have to be careful about what this mean. How does it affect small companies, that may not have the time to produce documentation, or very integrated products that can't really be repaired (which, if there is an exception, becomes a loophole big companies will use, of course).

I don't think taking precautions for your laptop battery matters much nowadays : you can expect it to last at least 3 years.

And you're not even sure that you're going to make it last much longer by storing it at 40% or draining it once a month (or whatever is the myth du jour).
I use the book of faces specifically for keeping in touch with family from a distance. I think it will be the same for kids when they grow up. They move away and they will join facebook.
I find the evolution of the menu bar fascinating. It's really interesting that the menu bar kind of started as command buttons attached to the windows.

It's interesting that over the last 30 years the Mac has been evolving back to the old version. Almost all apps now have toolbars that replace the functions of the menu bar. People have stopped using the top menu bar. As a software developer, I regularly get feature requests for functions that already exist, because there is no toolbar button to activate them, and people don't look at the menus anymore.

The latest beta version of OS X, El Capitan, even has a setting to hide the menu bar.

I've always thought that the menu bar at the top of the screen was so fundamental to the Mac experience, but it seems we've gone full circle, back to the original idea of command buttons attached to each window...
You betcha : this game would have to become massively viral to reach these kind of numbers. Heck a one million --downloaded-- app is already considered a success.
After 30 years of bringing things into existence via mere incantation, I still forgive them.
Pirates of the Silicon Valley is as much about Microsoft as it is about Apple.
I do indeed spend time in /new upvoting - seems like a decent thing to do.

However, that's not a great technique for finding valuable content, in my experience - the signal-to-noise ratio is rather biased in favour of the noise :)

Hence asking for advice. It wasn't meant as a complaint: if the groupmind of HN has decided it doesn't love entrepreneurship content, that's fine. But given there are a lot of other entrepreneurs on HN, I figured that one or more of them would know if entrepreneur-central had moved!
Now out only problem is how to build decoupled/distributed micro services.

I'd argue only Erlang and Elixir are going to survive into the multi core multi server future, but that would be little more than a slightly educated opinion unless I take the time to write a very large explanation with cited references. I don't have time for that this week.

One additional risk is what happened in Spain and Ireland though. A lot of property stands empty there still.
Wow! That is cool, it will definitely be a feature, we saw that there were many requests for this kind of drag & drop items.
A neat system might be, when the reciprocation system gets more advanced, to allow for nodes to build up a reputation/trust with other nodes while they're at home sitting on charge/wifi. Then, they can 'cash in' these brownie points when they're out and about, to download stuff without reuploading anything at the time.

There are a number of ways this reputation could be represented, perhaps one possible approach might involve exchanging some unit of cryptocurrency (Filecoin?), or perhaps a web-of-trust style system where nodes publicly 'trust' other nodes based on how much use that node was to them. Personally, I think cryptocurrency is the way to go here, but there's lots of work out there on P2P incentivization strategies.

Of course, this could work in tandem with the standard barter system that bittorrent uses, IPFS is not locked into any one reciprocation algorithm and could happily use multiple different systems depending on the situation.
Already there: WhatsApp, Instagram, Tumblr to name the biggest ones. For example Instagram has more active users than Twitter!
I think "tweet" should count. People say "Facebook me" too. I hear both more regularly than "uber," in fact I can't remember a anyone using it as a verb but that's just because an uber is something you get rather than do. I don't taxi over to your house either.
Hey All - we would love to get any feedback / critique on WikiPop or hear thoughts on this topic (extinction / wildlife conservation)... The organizations we are highlighting are doing great work and while some are well known others deserve a lot more exposure and support... Thanks!
Some of your feedback is interesting opinion, but the tags are relevant to the UX article. No, it's not "scraping a bunch of websites and mass include stuff". Anyway, thanks for the feedback.

The reason why they get people to sign up at other people's pods is that it's easier to get users that way.
They are struggling to get users regardless and that is their biggest flaw.

>I'd like to see more subways in terms of getting around, but there is plenty of logic in arguing for BRT over trains

BRT can't move nearly as many people as trains can. It would take many more buses to move the same amount of people. In a dense urban environment, trains make the most sense. In an area that's not dense, trains can allow density to happen. See the development of New York for instance. Plenty of trains went through fields at the time, and the railroads made huge amounts of money off of developing this now useful land (amongst other things). I suppose that's the real reason you get folks in the Bay Area to fight against trains.

The other issue we have in the US is our infrastructure costs are way out of line with the world norm. If the Second Avenue Subway had similar per-mile costs to Tokyo subway extensions (or even the maglev they are building), the funding for the first phase would mostly get the subway the length of Manhattan.

Logically, that's the same. The chosen MAC is sent to your next hop and that's that.

Some devices store the MAC in some sort of writable NVRAM.
It feels a lot like people compare Ritchies death to Jobs as some kind of morbid team sport, especially because they died so closely together. Its incredibly juvenile and more than a little obnoxious.
Fair enough, I didn't mean to be condescending. I think you might like /r/startups more than the entrepreneur sub. :-)
Twitter at least helps people from different countries follow global current events, but do we even want a competitor for Facebook?
88% of the people in Marin county wanted to extend BART there, according to polling done at the time. Bridge officials didn't want it, and shopped around for an engineer to until they found one who said the Golden Gate bridge couldn't handle the trains.

The "it'll cause sprawl" narrative apparently did not play much of a role in the actual politics of the planning process.
Lessons Backbone Developers Can Learn from React
I have grade school kids and the testing regime is brutal and the educational system produces about twice as many teachers as the economy needs so a teacher who's kids don't improve enough on multiple choice tests will have their career destroyed, which means a financial death penalty because the student loans can't be discharged, which means the destruction of their lives and families lives. So its kind high stakes for the teachers.
Yeah, that will be the limit.

You can run a right wing, loudmouth, ignorant asshole as long as he hits some of the concerns of middle America.

But you'll never run someone with his background, no matter how smart he is. The conservative voters (and I'm thinking the camo and nascar group here, ie 95 percent of the country) are still hung up on "drug bad", "white good" and other one-syllable talking points.
I don't taxi over to your house either.

Well, not unless their house is at the end of a runway :)
I think (hope) that eventually these centralised monoliths will be taken over by distributed versions.

The Internet Of Things IoT will be a precursor to any device being a node in a massive mesh net. That means that I can run my own private, secure personal social node on my cell phone, or even on my toaster.

The front end app will literally just be a front. The backend processing can be done on any number of nano-cloud processing instances run by companies like Amazon or Microsoft.

Storage similarly will be outsourced, but all data will be protected at rest using strong encryption.
Because dublin is such a safe heaven to store data.

Been using this for a few months at work. I was originally a skeptic, as my experience with "drag-and-drop" coding hasn't been positive, but I've come around after using it for awhile.

The guys developing it are incredibly responsive. I submitted a bug one morning via the mail list at around 9 am, and by 11am they had a patch slated for their next release.
Reactive WebRTC conference
Consider the t0 the moment of site starting and t1 the moment you add SSL to your site. All the FB, Twitter, etc. shares are stored according to the complete URL string. All the posts between the t0 and t1 will have the URL without 'S' and all the posts between t1 and 'now' will have the URL with 'S'. You can collect the shares from the FB API but you must provide the post URL and then concatenate the results. With this method you can preserve the shares, but we must keep this in mind: a share is registered with a single URL string, and also we must consider this transition as a one way transition and don't change it back to HTTP.

The next wave of social networks will most likely be decentralized. At the moment the concept is not yet clear, so no company to follow yet.
If you had the full documentation on all the systems on a car you could also reset the odometer before selling it to someone else, or turn off the alarm system and unlock the doors.

Before the recent examples of using internet connected entertainment systems to hack cars there was a case where someone found that there was a vehicle bus connector in the wheel arch of certain vehicles, plug into it and you could do anything to the car from outside.
Totally agree with your point. I'm 33 and aware the young generation is using a different toolbet.
Brilliant article and fantastic intro, though I think some key concepts aren't discussed at all, such as bias and variance. Looking forward to future articles.

Everything ends. Given how fast these companies rise up, I expect they'll be replaced just as quickly. For instance: myspace.
Well Instagram and WhatsApp are owned by Facebook :)
When AOL first entered the market, you could only send E-Mail to other AOL users. Eventually, faced with the potential of users leaving their platform for more interoperable (if less full-featured) alternatives, AOL relented and made their email system a proper, standards-based utility.

Now, granted that scenario is not a great example as email existed as a standard long before AOL came into existence, but I do think that as the number of users on Facebook/Twitter reach their inevitable peak, those companies, too, will be faced with the need to open the gates on their walled garden.

It's interesting that, thus far, both companies have delayed such a situation from arising by buying-out the other platforms people have been moving too (Instagram, Vine, etc.) and incorporating them ever-more-tightly with the parent platform. At some point, though, I think (hope?) this strategy will prove untenable and open interoperability will once again rule the web.

Call it crazy speculation, but I could foresee a resurgence of RSS/Atom eventually doing to Facebook/Twitter what SMTP/POP/IMAP did to AOL. If you think about it, the only thing that RSS/Atom was ever missing from becoming what Facebook/Twitter are today is a central aggregation point in the cloud. A smart startup that pulls a user's Facebook/Twitter feeds and mixes in any other RSS/Atom, as well as allowing users to post back to Facebook/Twitter/Atom could potentially spell the death of proprietary timelines.
Video streaming is mentioned, but I don't see how this works for streaming, unless the metadata is the content. Is this right?

HTree Upto 57% faster data indexing
Hi there

I am Hemen, I discovered a patentable algorithm called hTree (http://htree.space). It provides upto 57% faster data retrieval compared to binary search tree.
Faster data retrieval means cost time saving.
As estimated it can save computational energy by one nuclear power station per year. I believe this is big change.

Looking for the funds in my venture. It will be great if anyone can connect me with someone who is interest in this field.

Here is my contact detail for detailed business plan and funds requirements.

I participated in an REU a couple years back working with Named Data Networking. Seems pretty similar... The ahem central problem lies with ourselves: TCP/IP was designed as a communication network, not a distribution network. NDN seeks to be a ubiquitous data distribution network. Iirc, the design helps fend off DDoS.

Journalism is Dead
Ask HN: Who do you use for hosting?
I know this is potential spam bait but what hosting solutions do you use for what different projects and why?
And I'm always amazed at the lengths people will go to in pushing the "Google is an ad company" trope.

Your argument doesn't make sense, especially not with the rapid migration of traffic to SSL (and no, Google aren't MITM'ing SSL connections). The lifetime value of a single family's worth of ad-eyeballs simply isn't there to justify an undertaking of the size of Fiber.

Yes, they are ultimately an ad-company, but that doesn't mean that there is always a single-hop connection between any Google activity and ad revenue. If there's an ad angle here, it's in enabling end users to consume much larger quantities of ad-supported content.
Not before we get a chip inside. Then it will connect us to "the matrix".
Both, like any Bittorrent client. The difference is it uses a library which prioritises certain file chunks so that you can watch it as you download (stream it).
If this was open source software that people could install on their own hosting account (PHP/MySql) as a kind of personal social app then great and social meant loosely linked distributed nodes then that's exactly what I'm looking for.

If you are going to compete directly with Facebook, and manage to get funded and build a good team, then welcome your forthcoming Facebook acquihire. :-)
A universal distributed file system that looks native on my system (thanks to FUSE) and caches content I access locally, while serving it securely to others, is interesting... assuming you can solve key problems like search, identity when you want it, privacy when you dont, and human memorable addressing... which afaict IPFS doesn't address.

The "permanent web" on the other hand you can create using MHT archive files and BitTorrent magnet links. I struggle to get excited about that.

Wake me up when someone figures out how to make apps that require seamless multi-user collaboration, like say distributed clones of HN, Facebook or Github.
Any specific recommendations from anyone?
If you're a beginner, you're probably going to be too overwhelmed by the options. I often find emailing/asking a few different professors/researchers/students in the field you want to learn for suggestions more productive.

That's not to say this isn't helpful. This is from my own personal experience.
Really like the idea about our own distributed/private-cloud version but I struggle to see ordinary users using it.
Depends on what you want to learn.
Reminds me how Usenet binaries are often posted along with par2 files.

"Replace" is a loaded term in the sense that it implies these are categories dominated by one player. I think the reality of these kinds of services is that they overlap each other to various degrees rather than replace. People can use facebook, twitter, linkedin, HN, etc. etc. simultaneously.

So if you mean will other services in that general fuzzy category become popular, the answer is 100% yes. It's happening all the time. Whatsapp, snapshot, whatnot. These pop up all the time and many get traction.

If you mean will Twitter & Facebook loose popularity, that's harder to answer. But, I think it's reasonably likely. They're basically mediums for online culture and online cult evolves fast. It also depends on your horizon. If the question is "will a large portion of humans check Facebook daily in 100 years?" that seems pretty unlikely.

Why are you hijacking my scroll speed...

Your "smooth-scroll" library is completely breaking my touchpad scroll with an Acer c720 Chromebook. One slight movement (which should be a few pixels scroll) is moving me over half-way down the screen. Makes your site unusable with this touchpad as accidental scrolling sometimes happens and moves the screen a whole page away, especially when trying to right click open links because the gestures are similar.
