How to Start a Django Rest Framework Project in GitHub
I'd like to know who funded the research.

The Economist also reported it, and explicitly made the point that a hotel chain can use this in their marketing. Where we normally think of unique as being a good thing, this promotes consistency, so it's better to always stay in the same hotel chain instead of using Airbnb or whoever is cheapest on hotels.com.
I never claimed that, in fact I said precisely the opposite:

> Of course this isn't always the most interesting test
What many don't know about Kalman Filters (and took me a while to realize as well) is that it's just recursive least squares.

It is just formulated a bit differently such that incremental update complexity depends of the dimensionality of the observation, not the dimensionality of the estimated state. Depending on the dimensions this can be a lot more efficient.
Still it sounds like the death of portability.

We are kind of crowning the right to rule of the x86 computer industry. llvm is very tied to apple, maybe it can extend to ARM. But it means that some HW platform that may be to old may be difficult to maintain in the future (HPPA, Dec alpha, MIPS, PDP, zseries?).

And some computers have life cycle that are more than 10 years. (Expensive industry robots, telco switches, some medical devices, aeronautic/space CPU, radars, some very old mainframe used for accounting, embedded automation devices)...

Is this push to obsolescence really cool?

Okay critical system already handle the problem, but what about the stuff in the grey zone? Stuff that were not critical but get adopted nonetheless because they just worked and good be updated?
I think it is surprising we didn't see any breach of data from an advertising network yet, given the shady nature of that industry.
I agree with this statement (depending on how you interpret "change": if the world was different we may have been lead to prove different theorems), and nothing I've said previously contradicts it.
Ask HN: How do I build trust as a remote developer
I recently got hired as a remote developer for a startup in Germany, I'm about one month in.

So recently I have not been able to be very productive and spend too much time on tasks, I'm supposed to work for 8 hours everyday but sometimes I end up working for only 6 hours reasons are between time spend commuting to a co-working space, poor time management and some personal issues.

I have now realized that my bosses are not too comfortable with me and I have sorted out my personal issues, setup a proper home work environment and ready to put in my best.

How do I build trust back.

PS: I work from my home in Africa.

Thanks in advance.

We're not planning to release the Elasticsearch functionality for EE. But if there is anything we can easily do to improve searching in CE we're open to that.
Went to the article expecting more of a technical stack but found instead lot of side tools, some quite common but some I did not know. I'd like to add some we use at our startup which we found quite useful as well to integrate:

Chargebee - good merchant api, quite cheap for startups

Intercom - quite pricey for what it does but the filtering and automation features cannot be found on competitors yet

Ritetag - good social analytic api if you need to integrate keyword scoring for some reason

Quu - to use on top of buffer to pad your content if in need

We are working in the space of one of the named services so I'll refrain from naming ours ;)

>>> The marginal cost of producing another copy of digitally encoded product is essentially zero, and it requires zero specialist knowledge. Copying binary data is what computers are made for, it's their basic function. Plus, the Internet lets you scale a digital business to the whole world for (almost) free. Honestly, what feels entitled is expecting that one should be able to scale their business by orders of magnitude while retaining the price.

Well, it can be said about most of the SaaS companies but that's not how business works. If it doesn't cost you anything to produce, then you should give it away for free might look great at first sight but it's not that great in reality. So if the business is just giving away the product for free, why would someone pay for that? You might say extra features, etc. But they are free to distribute as well!

If we apply this to the physical products, you can equally say that the companies shouldn't charge more than it costs to produce something. But if all companies worked this way, that would take us back to the stone age pretty quickly.

Money motivates people, motivate people produce goods.

Floating point is already incredibly imprecise. The thought of debugging any piece of software on this system sends shivers down my spine.

I would much rather see something like UNUMS (https://news.ycombinator.com/item?id=9943589), which provide improved accuracy AND energy efficiency over IEEE floating point.
using actively maintained free software projects is rarely much fun, since many of them tend to often abandon old features and introduce new incompatible ones

GNOME has a lot to answer for. Most other projects try hard to avoid this and lean the other way, preserving ancient features at the cost of clarity.
Well it wasn't that long ago that a study found that school buses had many times the acceptable levels of pollutants inside because they sat idling while waiting for kids.

All I have to do is watch the local bus service, mostly the city one, to see how bad some vehicles pollute. So let us be honest here, the government needs to clamp down hard on all vehicles in its employ at all levels even more than going after consumer cars

> They're not directly comparable, but kdb+ would crush InfluxDB head to head in an apple/orange comparison if used for the same thing. I actually can't think of any time series-like store that remotely comes close to the feats I have seen kdb+ with Q accomplish. Too bad the productivity and knowledge overhead is so high.

Do you have any more specific use cases for the kind of analysis that kdb+ is used for? I'm working with timeseries sources that represent streams from internal variables from embedded systems and would like to evaluate whether kdb+ brings something to the table that we could use. (What we are doing probably falls into the category Complex Event Processing, i.e. windowed operations on the data stream with some predicates being evaluated globally.)

Well motortrend has this real world mileage test where they hook up an complex looking device to the back of the car. Something like that surely can be employed by manufacturers, magazines, colleges, etc, and the EPA.

From reading the article it should not be difficult to extend the testing abilities to cover all pollutants you want to measure

Hrm. I've bashed out quite a bit of crazy brand Ruby to achieve some cool looking interface. I wouldn't do this in production code.

The problem is of definition. My definition of clean is readable, clear and understandable. If it takes a significant portion of a blog post and the research before hand to understand what the hell is going on, I wouldn't call that clean as I define it.

Ideally, you want code that is understood quickly so that it can be maintained with the least effort. Seeing an object used as module violates my understanding of how modules were designed to be used and I would have to spend time figuring out how. It may be 2 minutes or 10 but regardless it's time that need not have been spent.

Cool magic can sometimes be helpful. Often its just cool.
Not because of the bots (clearly, as Elixir is hyping for longer than chatbots kickback) but it could still be a fad. Only time knows. Why no learn a fad tho?

But that's what happens in the physical world in face of competition (and that's the "great promise of capitalism", btw.) - prices fall down to minimal sustainable level unless someone is able to erect some artificial structure that will inflate them (like enough layers of middlemen).

But anyway, I don't mind Coursera or others trying out any business model they want. But them talking about a "mission to ensure access to education to everyone", etc.? This is getting dishonest.

Mobile Development Trends in 2016
More and more websites block those though. I'm using some HN app on iphone a lot, and for articles from the New York Times and such, all you get is a summary and a 'read more' link, which gives you a page covered halfway with the (obligatory EU) cookie thing (every time) and with a 'subscribe now' banner.
The problem is that even with co-workers at the same bank, or one's "society for foo" it's extremely difficult and rare to hangout after a certain age.

There are so many (work and self-imposed) obligations and "obligations" and BS, that it's even difficult to have quality/fun time with one's spouse.

And this certainly cannot be explained away with "the spouse is a tiny part of your current experience/identity".

So I think this answer doesn't cover the actual issue.

And it's not just workload either. Someone else writes below:

>In order to have impromptu visits that fill up the empty spaces in your life, you first need to have empty spaces in your life. That is largely incompatible with filling every moment of your life with work or career advancement.

But the lack of "impromptu visits" is also apparent in people who don't fill every moment of their life with work or career advancement. The killing of community/communal spaces, the advent of 100 TV channels and 8 billion internet/"social" options etc, also kill a lot of such time.
The problem with newspapers is that if they paywall all of their articles, they won't get any viewers because nobody knows what kind of articles they write without subscribing. A lot of them have an 'X free articles per month' thing, but since I'm on three different machines, I've never hit that limit unless it was like one or two a month.

Well, turns out you do have a very pragmatic clue!

Maybe. But the Jobs attire is not so special that people wouldn't wear it unless they were trying to emulate him. If I had to pick on dress to wear every single day of my life, it would probably be a grey turtleneck - pretty close.
>Since all these cars passed the laboratory test, that means there must be something very wrong with the test and the way the standards are enforced.

It depends how the law is written.

Case a) - the cars must never emit more pollutants than specified in these rules - then yes, you are correct. The car manufacturers would be rightly concerned about the wide range of situations they would need to account for.

Case b) - the cars must not emit more than the specified amount of pollutants under these specific test conditions (implying hopefully "we understand that the real world performance will differ, and are willing to accept this for the sake of simplicity in testing/lawmaking") - in this case the system is working as intended.

I am not sure which case we are dealing with, maybe someone can advise us.

Why is this called "dark patterns"? It seems that it can be more accurately described by calling it deliberately misleading or deceptive design. Clicking the link I had no idea what it meant. Terminology like this makes sense when the concept can't already be described using two words.

As for the content of the article, it has always seemed anti-user to me for a website to prompt for a subscription 30 seconds into browsing a page. I wonder if anyone has actually investigated the effect it has on traffic properly, because I always go back whenever I get prompted to subscribe.

If someone had told me in 2005 that in the future, intrusive popups would work its way back into the domains of acceptable design to the point where people will gladly have them on their personal blogs I would have laughed in disbelief. Together with "You have an outdated browser" ("Please view this in Netscape 4.0"), "Rotate your device" ("Best viewed in 800x600") this is all a terrible setback in acceptable practices.

Add to that some more recent design patterns like a "share on <social media>" button taking up 1/5 of the screen estate following you through the page only for the benefit of the publisher and the handful of users that also actively use twitter, weird overloading of scrolling behavior, "Continue reading" buttons... It's an awful mess and especially for websites that ideally would just present plain written text with some pictures it seems like designers are over-engineering their solutions for goals that in no way aligned with those of the users.

The two most-common commercial options are Impinj and ThingMagic readers. Neither are open-source (hardware or firmware) -- they just have APIs. If you go back to the old ThingMagic M5e (rather than newer M6e), there are high-level open source libraries that I wrote:

You can buy single-chip readers from AMS (eg. on DigiKey) and build your own reader -- not a light undertaking due to RF PCB layouts, but manageable. I've also heard of people using the USRP (GNU Radio) to build gen2-compliant UHF RFID readers, but I believe they require the PCI-bus variant to adhere to protocol timing standards.
