Finally, people are beginning to realize the insanity of this entire PATENTS file situation!

When I first brought up how misguided people were for embracing React and projects with this license, I was downvoted to hell on HN. But really, everyone, THINK ABOUT IT. This is a company that glorifies and celebrates IP theft from others, and lionizes their employees who successfully clone others projects. Theyve built their entire business on the back of open source software that wasnt ever encumbered with the sort of nonsense theyve attached to their own projects. And this industry is just going to let them have it, because the stuff they are putting out is shiny and convenient and free?

Having known so many people involved with Facebook for so long, I have come up with a phrase to describe the cultural phenomenon Ive witnessed among them ladder kicking. Basically, people who get a leg up from others, and then do everything in their power to ensure nobody else manages to get there. No, its not human nature or how it works. Silicon Valley and the tech industry at large werent built by these sorts of people, and we need to be more active in preventing this mind-virus from spreading.

By the way, the fact that Facebook is using this on their mostly-derivative nonsense isnt what should concern you. Its that Google has decided, as a defensive measure, to copy Facebooks move. Take a look at the code repo for Fuschia and youll see what I mean. Imagine if using Kubernetes meant you could never sue Google?

I think this is an overreaction (pun accidental).

There are two things here: The copyright license, and the patent grant. Copyright applies to the concrete implementation. You have to agree to the license to be subject to it, and to legally use the code.

A potential patent applies to any implementation. Even if you write a clean-room clone of React, if it uses the same patent, Facebook has a patent claim. But that means the patent grant is not specific to the code; it doesn't even require consent, Facebook could allow you conditional patent usage even without your knowledge! A corollary is that you are strictly better off with the patent grant, it imposes no additional constraints on you.

License with no patent grant: Facebook can sue you for infringing patents, even if you are using a clone!

License with patent grant: Facebook cannot sue you for infringing patents, unless you do it first.


Second, I think the philosophy behind the patent grant is twofold: 1) that software patents are not legitimate. Enforcing a patent is not seen as a legitimate right, but an annoyance, like pissing on someones lawn. From that point of view, it seems not asked too much from somebody to refrain from doing that. (I don't know if that was the idea of the people who drafted that license, but it wouldn't surprise me.)


Another, unrelated observation (and please don't invalidate the first observations if this one is wrong as internet commentators are wont to do):

I see nowhere in the license [1] that it requires you to take the patent grant. Is that true? It would be silly to refuse it, because you are strictly better off with it, of course.

I was interested in React based on what I'd read and was figuring it'd be worth looking into, but this provides all the reason I need to avoid it - I don't forsee a situation where I would personally or as a small company be suing Facebook, but I could see developing something then selling/trying to sell it to a larger company. If my code comes with a big side of "oh, and if you buy this you won't be able to sue Facebook or its affiliated companies for patent infringement" that could significantly hurt sales chances.

I really have no idea why react is so popular with such a silly license.

I agree with this move.

There are plenty of OSS projects out there without patent thing attached to its license so no reason to use react.

Reading a bit more the thread, it's quite surprising. The assignee is Chris Mattmann. From his webpage, he is not a legal counsel. The only evidence of a problem they show is that BSD alone implies a patent grant but coupled with an explicit patent grant, this is not the case anymore. The other evidence is brought by Roy Fielding who does not appear to be a legal counsel either about a discussion (oral?) with Facebook's legal counsel that the license is incompatible with ASLv2.

The whole decision seems to have been taken by "not-a-lawyer" people with their own interpretations. Doesn't the Apache Foundation have some software lawyers they can ask?

If Facebook has patents that cover React functionality. They almost certainly cover parts of other JavaScript frameworks. React is well executed, but it's conceptually simple.

I don't think avoiding React makes you any safer. You don't know how broadly Facebook or the courts will interpret their patents.

I found this [1]:

> FB is not interested in pursuing the more draconian possibilities of the BSD+patents license. If that is true, there is actually very little difference between BSD+patents and the Apache license. As such, relicensing should make little if any pragmatic difference to Facebook.

So what happens if Facebook doesn't change the license and in the future changes its mind?

INAL - But this seems strange to me. The Apache license has what I see as being the same patent grant, with the same condition that if you make a claim against them, you lose the patent grant.

Apache 2.0

> 3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

The important bit being...

But what people seem to be missing (as far as I can tell) is that you don't lose the licence to use the software. You just lose the patent grants. But with the BSD licence alone, you lose both the patent grand AND the licence. I really don't see how the Apache 2.0 License and Facebook's BSD+Patent Grant are any different.

I was wondering about a similar issue for zstd compression library. It has a similar BSD+Patentsfile thing.

There is an issue with a related discussion about it going for more than a year:


Last update is interesting. Someone did a search and looked for any patents FB filed for and couldn't find any in last year. So somehow based on that they decided things are "OK".

To quote:


US allows to patent up to a year after the publication, allowing to conclude that ZSTD remains free of patents (?) - suggesting this "The license granted hereunder will terminate, automatically and without notice (...)" from PATENTS file has no legal meaning (?)


Anyone care to validate how true that statement is?

I don't understand how code with a bsd license without a patent grant is better for the apache foundation than facebook's bsd + patent license. With the former, the entity donating the source can sue you for patent infringement at any time.

Clearly the apache 2 license would be preferable (and what rocks db did), but I am puzzled the foundation accepts bsd code in their products, given their worry about patents.

So if I understand correctly, by using React, you agree that if you sue Facebook, you'll need to stop using React? And that goes no matter the reason why you're suing them for?

So say Facebook was infringing on one of your patent, you could still sue them, but you'd have to give up React if you did. Is that correct?

In the discussion they say RocksDB will be relicensed under dual license Apache 2 and GPL 2.

There's already an issue [0] asking them to consider doing something similar for react, and Dan Abramov said he'd route the request internally on the next work day.

I can't imagine they'd keep the existing license without harming their community image. But even if they keep the license, many applications should be able to easily migrate to preact [1] and preact-compat, which provides a react-compatible API.

Hopefully they relicense the project. It seems like it's the first thing that gets brought up each time react gets mentioned.

If you don't have a product yet or the parameters could change quickly with new business insight, you need to be able to change it fast. With microservices you will be spending half your time figuring out orchestration, building data flows that people can understand, and doing ops. Last startup I was in delayed their launch date for >6 months because of their architecture. Way too many people think they need it, but a load balanced monolith can take you from 0 income to able to hire more engineers.

I all comes back to Conway's Law (Your software will look like your organization).

Microservices allow and require low coupling in the organization. If you want to reduce coupling in your org, you'll be well served by microservices. If you want tight collaboration in your org, you'll be well served by a monolith. As orgs grow into multiple independently executing units, a monolith starts to limit the ability to independently execute.

morphemass 10 hours ago 1 reply      
Just about every one I've interviewed with recently has been breaking their monolith up into micro-services for some reason.

When I've done this in the past I had a key goal: reliability. The cost was about 10x the development effort of the monolith in order to add an extra 9 to the reliability. The monolith was wonderful for getting up and running quickly as a business solution but it actually crippled the business because they had failed to identify how essential reliability was. KYC.

Personally I've come to the conclusion that the main benefits of SOA/MSA are not necessarily technical but more organisational/sociological. Having distinct silos of activity/responsibility, separate teams and communications channels; all can make a large project more manageable than the monolith by allowing the lower level problems to be abstracted away (from a management perspective).

The common pattern he mentions reminds me of the concept of 'semantic compression' (one big function and lots of variables first, then break it up into structs, classes, functions, etc.) by Casey Muratori: https://mollyrocket.com/casey/stream_0019.html

It's a very nice and natural way to write code to do it all horribly dirty and only when a sizeable portion if ready to start cleaning it up and making it look and read good.

Both are basically "good comes from evolving/refining bad".

I agree, monolith first and have proposed a talks to few JS conferences on this topic. I however have not worked in a company that uses microservices architecture at a big scale (like uber, instagram, etc). I am keen to understand - (1) what does it mean to run a microservices architecture from an org. point of view? (2) How are principles like 3 depths deep enforced? (3) How does a developer decide to create a new microservice vs when to reuse one? (4) Who manages the persistence layer and associated devops tasks (backups, failover, repset, etc)? ... mostly that is the uncovered bits for me. I came across a very recent talk by uber on these lines - JS at Scale (https://www.youtube.com/watch?v=P7ek4scVCB8). I think a few talks on the organizational side of microservices would give people a clear idea if they really need one. Also, though the startups use the term microservices, but their architecture does not in reality has as many boxes as compared to the uber talks that most of us listen to. The startup microservice architectures do have single point of failures and they just break it up to make it easier to scale beyond a 100 or so concurrent users. The decomposition is mostly around tasks that are IO bound (serving APIs) and other tasks that are more CPU bound (some primary usecase). So startups using microservices may not be that bad actually. They could just mean that we do an RPC using redis for some computationally intensive usecase.

I disagree with this, but only because it makes the assumption you're working with a single core type language, like java, python or C++.

I think if you design fault tolerant micro service based services with something like the erlang BEAM VM, things will workout well, since you're being very careful about message passing from the beginning.

> Almost all the cases where I've heard of a system that was built as a microservice system from scratch, it has ended up in serious trouble.

I wholeheartedly disagree with this point.

I've found that if I build monolith first, it becomes harder to draw the line of how to separate endpoints, services, and code within the system(s).

If I design in a "microservice first," or just a service oriented design -- I find that there is much more clarity in system design. In terms of exposing parts of a system, I find that the microservice first approach makes me consider future optimizations, such as caching policies, whereas, in a monolith, I would proceed in a naive, "I'll figure it out later" approach.

Each school of thought has its downsides. Monoliths move fast and abstracting parts of the system later that arise as bottlenecks is a tried and true pattern; however, there aren't too many product / business folks who want to hear:

"Hey, we just built this great MVP for you. It probably won't handle significant load, so we're going to go off in a corner and make it do that now. Oh yeah, we won't have time to develop new features because we'll be too busy migrating tests and writing the ones we didn't write in the beginning."

The flip side is, microservice first has a lot of overhead, and (as things evolve in one system) refactoring can be extremely painful. This is an okay trade off where I'm at... for others, maybe not so much.

Fowler failed miserably when building a monolith. See: https://en.wikipedia.org/wiki/Chrysler_Comprehensive_Compens...

Why should we believe his statements about microservices?

Personally, my experience in microservices vs monolith has been as follows:

If your system needs fast update with quick rollout of new features, monolith is probably superior. Being able to touch everything quickly and redeploy is generally quicker in a monolith.

If your system needs to be able to survive component latency/failure, microservices are probably superior. You will have hard separation that enables testability from the beginning.

Overall, I find the monolith vs microservices debate insipid. We have LOTS of counterexamples. Practically everybody writing Erlang laughs at people building a monolith.

Last year I worked at an electronic publishing firm which had wasted $3 million and 5 years on a Ruby On Rails application which was universally hated by the staff, and which we replaced with 6 clean, separate services. The problem with the Ruby On Rails app is that it was trying to be everything to everyone, which is a common problem for monoliths in corporate environments. But the needs of the marketing department were very different from the needs of the publishing department. A request for a new feature would come in from the blogging/content division which would be added to the Ruby On Rails app, even though it slowed the app down for everyone else.

Six separate services allowed multiple benefits:

1.) each service was smaller and faster

2.) each service was focused on the real needs of its users

3.) each service was free to evolve without harming the people who did not use the service

There was some duplication of code, which suggests a process that is the exact opposite of "Monolith First":

Start with separate services for each group of users, then later look to combine redundant code into some shared libraries.

In recent years where servers are to scale to many machines I found myself using less and less kennel threads. Also it seams GUIs are mostly web theses days. Most remaining fields I can imagine where you would want kennel threads, ocaml would not fit anyway because of GC and lack of control over memory layout.

I didn't see any gothic lolitas and those are just something that westerners would know about.

There must be 100s of substyles that are one-offs and produced by individuals.

Anyone know of more "street" pictures?

Well that was surprisingly tiring! I started to imagine keeping up with all those styles as they were happening -- sounds expensive. Fashion is inherently, I think, of the moment... in the "now"... and to lay out 37 years' worth of it in a row like that, has the probably unintended effect of laying bare its impermanence, frivolity (not in a good way) and unimportance.

What a horrible navigation. You can't freely scroll at your own pace, advancing with the keyboard is inconsistent, and what's worse, zoom is busted with keyboard and trackpad. This is a disservice to people with disabilities and people without them.

What's so wrong about regular scrolling? Why do designers feel the need to fight agains the browser? When a site decides to re-engineer basic user interactions (zoom, scrolling), the user has to focus on learning new behaviors instead of consuming your content (which is what they should be focused on).

The web has great UI patterns. Use them. Don't fight them.

It's sad to see a simple, well-designed, free, open-source project embracing the values of the HN crowd ("The TIO web app is free of charge, ad-free, and doesn't use tracking cookies or third-party analytic scripts.") -- and the top comment, as well as many others, are essentially a nitpick about a bug that can be trivially fixed.

If I recall the details correctly, there have been observations recently of another NRO satellite in a geostationary orbit above the middle east and west Asia, that apparently can maneuver and reposition itself.

And if I'm still not mistaken (may have been a different satellite) it was confirmed that this satellite had extraordinarily high communications bandwidth and was speculated to be used either for SIGINT or for operating UAVs.

Anyone interested in it, other classified satellites and classified things on the map in general should look up Trevor Paglen. He's a Geographer who's recently begun taking pretty spectacular shots of classified satellites.

Impossible 18 hours ago 1 reply      
The advice to not learn Vulkan first is actually pretty good, because it aligns with most people's goals when learning. Most people want to get some graphics on the screen and maybe understand what a shader is, how meshes are represented etc. OpenGL has less friction here, and I'd argue that you can learn a lot of this starting in a higher level environment like Unity, writing your own shaders and creating procedural meshes. This advice comes from the same place as "if you want to make a game don't write your own engine", which is probably works for most people.

Vulkan is great as a beginner if you want deep understanding of the graphics pipeline and are ok with some pain and confusion and a lot of "boilerplate", which comes from Vulkan having few defaults. Its a good representation of how game engines tend to use graphics APIs vs toy applications, academic projects and indie games you might see as smaller scale examples. As a beginner and a hobbyist you probably don't need Vulkan or DX12 for anything you'll build and you'll quickly be exposed to a lot of concepts you won't really understand, but I think sticking with it will give you a level of understanding much deeper than someone that dabbles with OpenGL.

Genteelisms are a curse in Italy, where bureaucracy reaches levels unknown in the UK. One of my favourites, because of its utter, revealing stupidity, is the sporadic usage by some overzealous bureaucrat of the verb "to implement" (recently brought to Italian from English) with the wrong meaning of "increment". As in:

"We're working to implement the number of bus rides from A to B".

It's fun because you can clearly see the mechanism in action: the person who wrote the sentence decided to replace the too understandable verb "to increment" with something so obscure he himself didn't know what it really means.

If crypto researchers would try working on actual user facing software they would probably come up with more useful designs. As the moment (1) you have to be insanely smart and careful to implement any reliable crypto (2) the crypto needs constant updates because researchers initial ideas are always full of weird unexpected holes (3) virtually all proposed crypto comes with multiple human interaction fails.

I wish it were better, and I completely understand that it's tough to both research higher order mathematics and keep in mind human level interactions, but without something like that , I think we're going to stay stuck with the current state of overly technical, fragile, normal-user-hostile tech.

"Isomorphic" templates are not enough. You also need isomorphic data fetching for client code. If you have to manually reinvent the same data fetching on the client and server, you don't get the full benefits of isomorphic code. You only have brittle templates with two different ways to glue data to view.

So far isomorphic Node + React has been the best (but not perfect) way I've seen to do this. You abstract out the API layer, and now you can define components and their data sources that have the exact same code on the client and server, and it just works. Apollo/GraphQL is probably a giant leap forward in this as well.

Having an option to do hand-glued "isomorphic" data in a few places is probably nicer than Javascript spaghetti on the front end, but it doesn't get you all the way there. Rails has the same problem by the way, the "Rails way" is coffeescript glue to get any kind of modern front end application functionality. Even with React on Rails you have to have to reinvent data fetching, and lose the benefit of a well structured isomorphic codebase.

Until browsers support a different language natively other than Javascript (which will never happen), Node + React is currently the most straightforward path to get there.

I was wondering if we should not code a Python renderer for one JS framework and be done with it.

We already have one JS engine in Python (https://github.com/kovidgoyal/dukpy). We even have pluggable renderers (https://pypi.python.org/pypi/PyExecJS). Later we will have webassembly renderers in Python, so you will be able to take frontend frameworks, compile them and execute them in Python.

Finally, we have some fantastic framework that are powerful, yet not that big, such as Vue.js, that already have a pluggable architecture for rendering without a DOM on the server side (https://ssr.vuejs.org/en/basic.html)

The Python community has done much more complicated projects already, and half the work is there, so my guess the reason it hasn't happened yet is we REALLY hate js and most of us just touch it to get the job done and go to the next task.

It's a bit like the async situation. We have the tools, but there is no Django of the asyncio because we love our tools as their are so much. I'm so guilty of this.

The problem is: the rest of the Web is moving ahead, and while it's still relevant to do DRF + Vue.JS right now, one day stuff like meteorjs will be so crazy yet stable it will be hard to compete.

I was hopping webassembly would let us eventually run Python on the client side. But I doubt it will happen. However, I'm thinking more and more than it will allow JS tooling to be plugged in many other languages on the server side.

The biggest problem is testability. Testing that a template renders correctly means parsing the markup into a DOM and asserting that certain conditions are met. This is exacerbated by the differences between Jinja and Nunjucks, which can be non-trivial and unexpected (e.g., Jinja will render synchronously, while Nunjucks can render asynchronously--weird async behavior may appear). Since your application doesn't have the same entry point to the code (they're in two different languages!), you really need to write two different sets of tests for the same template to get proper coverage. Templates being templates, you also don't get the granular testability of a React component out-of-the-box, which can be pulled out and tested individually.

Templates alone also don't include anything in the way of handling events, component lifecycle, and other things that make your code actually do stuff. You'll need to bind event listeners manually, and those will of course need their own separate tests.

Making Jinja useful also usually involves adding your own plugins and filters. This happens in Python, which means you'll need to write all of those a second time in JavaScript, and test them. Doing this right means comparing the output of the two versions, which isn't necessarily straightforward. Given the complexity of this, I wouldn't bet money that other engineers would go through the hassle of making sure this is done correctly.

I'd encourage the author to write more about the pitfalls of this approach. It's easy to write {{ foo.strip() }} in Jinja and forget that Nunjucks requires {{ foo.trim() }}, or empty arrays being falsey in Jinja and truthy in Nunjucks.

I actually wrote a JavaScript code generator for Jinja, which allows you to use the Jinja parser and AST and generate pretty readable and fairly sane JavaScript code (for a pretty large subset of full Jinja). I actually used this in my startup (now long dead) where we were able to reuse quite a lot of template code both on the server and the client.


This is in some (conceptual/experiential) ways a precursor to my recent attempt to create a Rusty Jinja-like, which tries hard to take the best ideas from Jinja and mash it up with the best ideas from Rust:

The post reads somewhat rambly, which I suppose is unavoidable if you're doing a quick whistle-stop of a bunch of related technologies showcasing a new idea.

The only thing that doesn't seem clear is why you'd need to combine server- and client-side rendering in a single instance. Jinja is an incredibly useful and well-made tool, and my experience of it with Flask always leaves me with the best impressions of it being exactly what quick webdev should be, but why would you combine it with JS? Surely the use cases are so different that a separate JS library would be just as applicable, and perhaps more fit for purpose.

cyberpanther 15 hours ago 2 replies      
I usually ignore server side rendering or isomorphic rendering. I'm not saying all projects should ignore it but you're really talking about a high level of optimization if you need it. And if you're reaching that level of optimization you probably shouldn't use Python.

Server side rendering only makes the first view faster. After that, everything is rendered on the client and faster that way. And if you use caching with progressive web apps or just file caching in general, the first view will be fast after. So you're only optimizing for the first of the first. You can then provide the initial data in the page request so that saves a round trip on the first request while still rendering on the frontend.

I say all this to just point out that there are many ways to speed up your frontend without doing SSR and they are much easier to implement with Python. So I'd rather exhaust all these techniques before implementing SSR. If I get to that point though, I suspect Python might be the slowest part of your stack. And lastly if you are doing SSR for SEO purposes then just use a prebuilt prerender service.

With all that said if there was an easier way to SSR with Python/Django, I'd definitely use it. But Jinja on the frontend doesn't sound like that answer.

I've been working on a site recently, in Rails, and just been using Turbolinks and SJR (Server Javascript Responses). Granted, it's a content heavy site with fairly light ajax interactions, but it's a pretty delightful process.

So many people jump to heavy JS libs/frameworks to do stuff that can be solved in much more boring/simple ways most of the time. You don't need React/Angular/Vue to submit a form over ajax.

Templates cause bugs. The solitary appropriate solution is an unparser a component that walks an AST and serializes it.

Making sure the result conforms to the grammar of the output language without any unparser would always involve a parser.

I've done this many years ago with https://github.com/wkral/jinja2js

It works - but there are gotchas:

1. You can't depend on useful pythonisms/javascriptisms such as

 {{thing or ""}} vs {{thing || ""}
2. Template filter code still has to be duplicated in both languages - i18n such as {{_('String')}} for example - which sort of makes sense - but then you have to do the same for some other, really trivial, filters.

3. Testing becomes annoying because a template can work in one, and not the other - you have to test both.

4. You don't get the newer html diff style virtual dom rendering which can cause issues with stuff like select boxes. You end up with special case code to handle that, which is more of a hassle.

The conclusions from it all were:

a) You do save time over doing it once in python, once in js

b) You don't save time over doing it all in js - especially if you use a newer functional style js template framework (react/vue/polymer)

c) You can still get the best of both worlds by hooking up your templates in js to be rendered by your backend - eg like https://github.com/reactjs/react-rails does.

In the end for my next project I decided to do an api for the backend in python and the website/frontend in react with SSR, and am really thrilled with the results - very maintainable, testable and simple overall.

If, like me, you were hoping to find code that is poetry, a few recommendations:

whytheluckystiff, or _why, was a very colorful persona in the early English-speaking Ruby community who wrote some very poetic code (some of it production grade) and inspired a lot of people (me included), and eventually disappeared one day when he was outed. Maybe start with Why's (Poignant) Guide to Programming that is a literary work that is also a Ruby tutorial, available at http://poignant.guide/, and continue by reading archives of his blog (where he posted hand-drawn and sometimes animated poetry in Ruby) and libraries he wrote (I strongly recommend Camping.rb, a 4k minimal MVC framework, that was at once very poetic and production-ready.)

Other than that, if you can read x86 asm I recommend this book of Koans/Poems/whatever you call them, written by someone I know and extremely beautiful: https://www.xorpd.net/pages/xchg_rax/snip_00.html

And in the Perl community there's a long tradition of polyglot perl/English poems: https://docstore.mik.ua/orelly/perl/prog3/ch27_02.htm

Yes, YES, this is what I'm talking about Microsoft. I'm surprised how muted the reaction is from HN here.

On the technical side, this is a perfect example of how AI can be used effectively, and is a (very obvious in hindsight) application of the cutting edge in scene understanding and HCI. There are quite a few recent and advanced techniques rolled into one product here, and although I haven't tried it out yet it seems fairly polished from the video. A whitepaper of how this works from the technical side would be fascinating, because even though I'm familiar with the relevant papers it's a long jump between the papers and this product.

On the social side, I think this is a commendable effort, and a fairly low hanging fruit to demonstrate the positive power of new ML techniques. On a site where every other AI article is full of comments (somewhat rightfully) despairing about the negative social aspects of AI and the associated large scale data collection, we should be excited about a tool that exists to improve lives most of us don't even realize need improving. This is the kind of thing I hope can inspire more developers to take the reins on beneficial AI applications.

Neat, although the fun begins when you try to fill them since you cannot just ignore the primitives anymore if a vertex touches the near plane but instead you have to clip the primitive :-). Also without a z-buffer hidden surface removal becomes tricky if you want to avoid bad overlaps.

For fun i made a 3D thing a few years ago, you can check it here:


The code does the clipping part (triRender function) although HSR is painter's algorithm with a simple sorting (triSort) with a heuristic (triCompare) that i came out through trial and error (because of the distortion introduced by the perspective projection this doesn't always work and IIRC i'd need to actually split the polygons for better result but i was too lazy for that :-P).

Note that i wrote this for fun a few years ago, i am not a web dev nor really follow web tech. This is the biggest block of JavaScript code i've written for years :-P.

This is called the sterile insect technique, and it is a well-established practice for getting rid of mosquito populations that could threaten humans. It is very safe, both to humans (male mosquitoes don't bite) and ecologically (species other than mosquitoes aren't affected at all).

It sounds like Google is working on improvements to the process. This is important work, because mosquitos are a major cause of disease, especially in Africa, and we haven't been able to fully solve the problem with existing technology.

I recall hearing when I was younger that mosquitoes were an outlier in the natural world. With most species, the balance of any food web would be pretty thoroughly disrupted by a major culling. As I heard it, this isn't the case for mosquitoes - if you could press a button and kill them all tomorrow, most ecosystems would be largely unimpacted.

Am I just making this up/misremembering it?

Edit: found a few sources.

They key regulatory factors cited against Oxitec, especially in their Florida Keys trials in the past year, were centered around controlling for the release of only males (which do not bite humans), thus avoiding transmission of any kind from the genetically modified varieties, or bacterially modified varieties in this case.

Oxitec has worked for years to filter their mosquitoes so only ~0.2% of the released mosquitoes are female[1]. They then had to demonstrate that and more in many trials before being allowed to release their mosquitoes in the wild in Panama and Florida.

Otherwise, it's great that Google can overstep the other factors that would stop this solution like NIMBYism and working with county / municipal boards. These solutions are great.

It's interesting that Google is doing this rather than some government organization. What's Google's motivation? Is it purely altruistic, a PR move, an experiment, or does it have some direct benefit to them?

From what is explained so far, this process doesn't kill mosquitoes. It just makes sure that some of the females (that reproduce 5 times in a life of 2 weeks as an adult) get fertilized with unproductive eggs. http://www.denguevirusnet.com/life-cycle-of-aedes-aegypti.ht... The eggs of aedes aegypti can be spread anywhere and the fertile hatch whenever their area gets wet in the next year or so.

Does anyone know what % population reduction impact this process results in? They'd have males likely die after 2 weeks and that just wipes the reproductive chances of the females in that period. Google is treating for 20 weeks in dry weather, which is not exactly the peak reproductive season of this mosquito.

Does this prevent reproduction of the mosquitos, or of the disease? If mosquitos, will this have a negative impact on bats? My bats eat mosquitos and moths, but there are not many moths any more.

Does anyone know why the mosquitoes wouldn't evolve to be repulsed by others infected in this way?

Or is this a similar class of problem to antibiotics becoming useless over time?

I.e. it's useful to do now so let's cross that bridge if we come to it?

Or is there something else I don't understand about this?

This may be an unpopular opinion but I feel strongly against titles like this. They could have very well gone with "...Facebook take Instagram Market share" but they wanted to make it personal and human.

I'm disgusted by the choice of words here. One company gained an advantage over there other in a market, big deal! They're competing businesses and eventually one will up the other but there's no point in saying "down to its knees"

The interesting flipside to the copycat issue is that Snapchat intentionally did not copy Instagram. And that was probably a mistake.

Spiegel was explicitly against the concept of "accumulative" profiles.[1] The accumulative feature they rolled out last year was Memories, a private gallery that only the user could see and show to people in person. And he was explicitly against making it easy to add tons of friends on Snapchat. He wanted it to be about your "seven most important people."[2]

Well, turns out people do in fact like their Instagram accumulative profiles to store and share highlights with their followers. And it turns out people like getting engagement and adulation from a broader network of followers.

So, as much as I dislike the crass copying that Instagram/Weil did and his attempt to pass it off as just a "format" -- that's bullshit, they copied vast aspects of Snapchat stories and messaging.. calling it a "format" is naked intellectual dishonesty. I noticed Weil back in the Twitter days and this intellectual dishonesty makes me respect him less.

But Snapchat also did not make the right strategic product decisions here. Spiegel, to his credit, went with a bold vision and strategic analysis about what people want. Turns out it was just wrong with respect to how people want to engage with and present their experiences to a broader set of friends.

I really dislike the feature of Instagram that imitates Snapchat. When a software tries to make more than one thing, it loses it's identity. I am surprised that people are still using it, but about the long run, nobody knows.

I saw a funny tweet that someone just wrote "A fear" than an image of Twitter print, of the mobile version, with small spheres on the top (like the ones suddenly appeared on Instagram), so I realized that it's not just me that think Instagram got worse with this feature. And the design solution they found, really annoys me. Now we have this on all Facebook products (WhatsApp and Facebook itself).

Talking about the software identity, I don't remember successful products that tries to do more than one thing. I think it's wrong, but it's apparently working, so I am observing and learning.

I am curious how many people actually feel this is cool that Facebook can simply copy everything Snapchat comes up with? I understand that this is the way of the world. Big fish eats smaller fish yada yada. But is it good in the long run? I don't know how to do this, and I understand any solution will probably be riddled to the core with loopholes. But I do feel like there should be some way to prevent this kind of monopolization. What do you all think from a long-term, idealistic perspective?

Most of this will come down to brand equity anyway. I have to assume there are people using Lyft over Uber because those people have negative associations with the Uber brand. Uber and Lyft both provide the same products, but people prefer one brand over another.

People prefer Gucci over Versace, North Face over Patagonia etc.

Inevitably, the same will be true for Facebook vs Snapchat. Snapchat will likely prevail in a way because the "brand" ecosystem, talent pool(pr, actors, producers etc.) are concentrated largely in Los Angeles due to the existing Hollywood system.

Proximity to the talent might not have much to do with it, but I imagine Snapchat has been developing those relationships for a while.

Instagrams revenues are increasing because Facebook advertisers unwittingly are having their ads run in Instragram. You have to opt-out. Found that out after blowing through and ad budget that got consumed more quickly because of Instragram.

Instagram users as a cohort are the worst audience for advertising. Low conversions, lots of impressions and just all around less profitable than the exact same ad on Facebook itself.

Even music acts that would seem to be a tailor made product for Instragram still, in my anecdotal experience, a complete waste of money. Instagram the thing might be a fun product, but Instagram as a provider of cost-effective advertising, no way.

At the time the DOJ began seriously looking into Microsoft about anti-trust abuses derived from their monopoly, there were still a vast number of medium to large software & tech companies that competed head on with Microsoft. That of course meant there were a large number of parties that could sign on to the aggrieved list against Microsoft.

As Facebook formally kills off Snapchat in the next few years, it's a curious problem of which companies will supply the ammunition to go after Facebook for anti-trust abuse. Said companies will be the biggest motivating factor for the US Government to act, their prompting will drive the case.

Given the scale we're talking about now (Facebook is already more profitable non-inflation adjusted than what Microsoft was at the height of its power; and they might double their profit in a few years up to $20 billion before any government action would come through). I would expect companies to begin lining up with their hands out. Twitter as one example, stands to easily land maybe $5 billion or more as compensation for being one of the few survivors of Facebook's social monopoly. Something that has changed a lot in the last 20 years, corporate fines & costs of negative legal outcomes have skyrocketed in practically every industry. Google's worsening EU disaster is just the latest example of that. Facebook will need tens of billions of dollars set aside for settling with governmental entities and competitors (even semi-dead competitors like MySpace - its owners will show up with their hands out for a settlement, and they'll definitely get some crumbs as Facebook will settle just to move on as the lawsuits stack high after the blood hits the water).

As the world witnesses Facebook intentionally kill off Snapchat by leveraging its monopoly in nearly every way it can, there are going to be few people remaining in the Facebook defender camp as the number of major social players in the US & EU markets drifts toward just a few small competitors left standing. Snapchat better have been worth it, as I can assure you that crushing Netscape wasn't worth what it cost Microsoft.
