As the founder of one of the hardware focused firms listed (ROOT/VENTURES -- http://root.vc) I couldn't be happier that the crew at bolt.io wrote this article.
I'm also a huge fan of HN, so if anyone has specific questions to ask about the VC approach to hardware, lets hear em.
The same we use today.

I suppose the complaint was to hint that mathematics that is older than 50 years is too old for modern tastes, but most of our modern notation was already established at the start of the 19th century. Even Euler uses almost completely modern notation, about 250 years ago.
One slightly obscure notation is for the evaluated definite integral - square brackets suffixed with the integral range.
This sounds like the age-old conflict that computer science students have long bemoaned: computer science is not software engineering.

If you're interested in algorithmic development and the actual theory of computer science, you'll probably enjoy most four-year degree programs in that area. If, however, you're studying computer science because you want to write software -- and that's what matters to you -- you're probably going to be frustrated that the coursework veers more strongly towards the theoretical.

I think that most college degrees are more about showing some sort of credential for inexperienced people than providing solid value in and of themselves, but I also don't think they're completely useless. It really depends what you're trying to do.
Ugh. (Current) copyright law is a cancer.

It would be interesting to see this as a formal proof, and to compare the complexity and lengths of both approaches.

I think it's a bit more than that. I suspect it's about not having uncontrolled (by Russia) sources of information for the Russian people.
I think that stuff like this and code boot camps, rather than online distance learning, is the real threat to traditional higher education.

In my time in academia, I was always struck by how uncomfortable academics were with the idea of university educations being vocational training, rather than education "for its own sake." It's a nice ideal, but almost all students, especially those in STEM fields, are in college to improve their career prospects. But academics are mainly focused on replicating themselves, i.e. focusing on teaching things that are useful to students who plan to attend graduate school in the field, but not useful to the majority of students who do not. This is how we end up with CS grads who can implement obscure data structures they will never use in industry but cannot do practical things like use version control or continuous integration, or write good unit tests.

For someone who wants to work in a technical field, I think new programs like this one, or like code boot camps, are becoming increasingly attractive as college tuition becomes more expensive and student loans become more burdensome. If employers are willing to hire graduates of these programs, traditional universities will have trouble attracting students. And they should.
Google is not even the most popular search engine in Russia. This is why Russian courts are commonly considered a running joke.
You just need to carry it, keep it in the nap sack or brief case or whatever, make a point of getting it out. Practice with it... You sort of want a mid-range beater at first, you don't want your dream camera, you want one that you know you'll beat up and replace.

Now the camera industry isn't the fastest moving, but all this means is DSLR and pocket cameras need/will to get better. I can see the low-end pocket cameras will disappear; phones are effectively that. I just can't see the various camera companies going down without a fight and arguably the people that buy and use $4000 cameras aren't the same market is those the buy galaxy phones. The bottom is getting better at a rapid clip though...
like many things there, it will do a fine job if the task at hand is putting nuclear missile into Washington, DC.
Of course he cheated, where as Larson simply took advantage of the system but played entirely within the rules.
Copyright has also been taken to its logical extreme in recent history, granting copyright terms that, in many cases, won't expire for 150 years or more from the date of publication, well beyond the lifespan of any human.

Copyright was supposed to be a compromise between the public and the rightsholder, where the public was willing to give up some of its natural right to copying and sharing in order to incentivize creativity. We've left all that in the dust now, and our copyright laws are currently based solely on scare tactics from massive media conglomerates.

IP reform is badly needed but I think we've still got a little ways to go before it seems so "common sense" that it occurs. Once the generation that grew up on Napster and its successors gets into their 50s, we might see some substantive change.
Excellent read. For those interested, here's a great companion piece: http://www.newyorker.com/magazine/2015/07/20/the-really-big-...

How is their universal SSL stuff being handled in China? Is there a separate root they use? Since certs are shared (with lots of SANs) if my site is sharing a cert with one that opts-in to China access, does that mean the private key for that cert is now available to China?
Exactly! I like this because now I have a very concrete piece of evidence that a place will be shitty to work at before accepting an offer
The developers of those platforms created distinctive OSs with distinctive features. They would certainly dispute that "90% of apps out there don't need that level of control." Their point of view is that they are innovating in the OS, and apps that take advantage of features unique to a platform will have an advantage over those that don't. On Android, there is no cross-platform equivalent to Android IPC and RPC mechanisms. No Android Wear or Android Automotive. No Android TV UI. No cross-platform printing. Etc.

If you don't need to push the features envelope of the mobile platforms you are targeting, and if you are OK with having L&F that isn't native, and if you are OK with the pace at which your cross-platform tools chase the native platforms, then cross-platform tools like React Native can be fine for you.
Experienced the same thing. Nearly had to kill my browser to unfreeze it, but fortunately I eventually got a Cmd+[ in there to get out.
And i'm saying they will hit kids, just like the Volvo hit the pedestrian.
Excellent news!

Normally at this point I'd ask if you were interested in fixing the libc for me, but frankly, it's not worth it --- clue's technology is pretty crappy. One day, in my copious free time, I'd like to retry the whole idea using a better compiler.
I've encountered worse. When I was in college, we used WebCT.

I'm fairly sure students could've written a better tool as a senior project.

(edit: oh, hey, Blackboard bought WebCT a while back. Eww.)
No. There's the analytic definition of sin that does not mention curves or lengths at all: the sine is the unique function that satisfies the following differential equation and initial value problem:

s''(x) + s(x) = 0
s(0) = 0
s'(0) = 1

It's a nifty way to define sine purely by its differential properties. Of course, it requires some work to show that differential equations have a solution and that this particular solution is sine (i.e. has the properties you want a sine to have), but once you do that work, it's pretty easy to prove things such as sin^2(x) + cos^2(x) = 1.

On the other hand, starting from the geometric definitions (and building the framework for that, such as arclength, which really requires calculus), it takes a longer route to get to the calculus of sine. Historically this was the route, but we have found shortcuts since then.
> What does this have to do with databases and declarative view objects?

Well, you can think of a cursor as a query into the state, with support for dependency tracking. I think your confusion is that you're asking "How is what you're describing like a cursor?" when I'm saying "Om Next is going to replace cursors with something very different."

...so you're right, it isn't the same as a cursor anymore, because swannodette is moving away from the cursor paradigm into more of a "querying" approach.

Ten to one that this is a backdoor geopolitical jab at the US.

Probably a silly question but do standard test rates apply? Do you get to customize who you want a quote from? For example, my favorites quotes are from Winston Churchill as opposed to Shia LaBeouf. So I'd like that in the morning... Looking forward to answers..:)
Don't you think it would hurry that process along if the prisons filled up with bankers?
It's really useful if you want a type to which you can cast any (non-float) primitive value and know that you can cast it back to the same value you had before. I've used it as the cell type for a Forth interpreter, for example (where cells have to be able to represent addresses as well as integers). It's probably particularly not useful for general applications programming.
I mean "use in the context of a much larger application with the minimum possible pain". If done right (a big if, I admit), all the other lines make it easier to use the "working" code than it would be if all the other lines weren't there. "Easier" means "over the scope of the whole project (or multiple projects)", not just "in this one place".

There's lots of ways to do the surrounding lines that don't actually do that, but that's the intent.
> How would that happen, exactly? Particularly with the GPL. If an author (company or otherwise) distributes their work, they're required to also provide the source for that work.

How that could happen is: Imagine in a world in which a free, open-source operating system is immensely popular, installed on most desktops, devices, servers and embedded systems. Suppose the system's distro ships bundled with some applications (also perfectly open-sourced).

If it is difficult to compete with those applications, how does it matter that they are open source?

Sure, you can make a fork of the distro which is unbundled, making it easier to replace appliactions. But, oops, hardware vendors don't want to ship the forked distro for whatever reasons. They say, "we install the image that 99% of the world uses. We don't charge anything extra; if you want something else, wipe the HD/flash and do a complete reinstall."

In this hypothetical world, would governments step in with anti-trust litigation? (Against what?)

For extra confusion points, let's add signing: suppose you can't even add an application to the distro if it doesn't have an approved signature from the upstream. (Isn't that essesentially Firefox started with add-ons?)
"coder boot camps" are for suckers.
I think the best part of this article was the small link to the F8 2015 "Big Code" video [0] where they go into detail about switching from Git to Mercurial, building their own IDE around Atom, and detailing their continuous integration process. It's a long video but it's very watchable using the YouTube speed multiplier. :)

Following that user in "web development" instead of "everything" (a la twitter) will solve his issue. You follow people within categories, you don't associate people with categories.

I probably didn't phrase it correctly, I stand corrected.

When you share or save something on tree, you have to choose one of the 20 categories: tech, business, news&society, art&design, music, etc... In turn, people will see that you shared in X or Y and can decide to follow you exclusively in this X or Y category. Your feed is actually a multi-feed (depending on how many categories you decided to follow people in, up to 20).

I honestly do not see how much effort would it take to get from <foo bar="baz">Quux</foo> syntax to ["foo", {bar: "baz"}, "Quux"] syntax. I believe someone already working with code (HTML, CSS) should be perfectly capable to learn this transformation in well under 15 minutes.
I read through the first three books of the Wheel of Time, but couldn't make it further. I may try again at some point. Did you also love Eye of the World?
This code is not only non-optimal, but also inneficient.

First, it does a linear search - O(n) time - because it keeps adding null pointers for elements that are removed from each list. This makes literally no sense. Just removing the null pointer insertion would already improve the performance a lot.

Second, the multiset is also a poor choice for the available objects list, given its performance characteristics. A structure like a deque, with O(1) insertion/removal on both ends, would be much more suited for the job.

There are a few papers/presentations on memory allocation for C++ from Andrei Alexandrescu, like this one: http://nwcpp.org/talks/2008/memory-allocation.screen.pdf

I'd suggest giving them a read, they give some good insights about simple yet very powerful techniques for improving memory allocation with little code.
It uses Dart. Which despite looking like a nice language, approximately nobody knows. So I'm not sure this is really an viable alternative.
I think a lot of early game companies suffered from not really believing in the market for games, that they were a placeholder until they could make something more 'serious'. Even non-computer game companies like SPI and Avalon Hill spent a lot of effort chasing corporate and military uses when in retrospect they underserved their fans and customers.
It was 10 years ago when I bought a laser printer for $150. It was such a fantastic printer that I bought another one for my mother. It was known even then that inkjet printers were scams sold at a loss in order to overcharge for ink.

How then could that be a mystery today?
do you need a mobile app or a mobile website ? that's the first question you need to ask yourself.
What you're missing is the usual scientific approaches don't work in psychology so they've turned to philosophers and "philosophers of science" to come up with ways of demonstrating truth. Psychology may be rigorous compared to philosophy but it isn't when compared to the hard sciences.

> The interesting part in fact is that it's not necessarily science or its methods that is at fault here...

The problem is we have "sciences" that don't use scientific rigor and may be incapable of handling tools as complex as p-values without misunderstanding and abusing them. To me it's the lack of science and its methods that's at fault here.
> To make this program useful it's probably necessary to add checks that power used by components is reasonable.

Indeed. It would also be interesting to see power consumption addressed in the cost function.

Our terrifying swim: Two Syrians' journey through dark waters to Greece
The bargain is probably something like: "Customers using our China POPs give us money. We like money."

And is it thought that China lacks the resources to infiltrate CloudFlare? The KGB compromised the CIA and FBI over many years for paltry sums (under a million). If China really wanted to extract IP they can certainly do so. While operational security (like HSMs and procedures) might stop people from walking off with key material, I find it really hard to believe companies can stop adversaries from walking off with source code, know-how, technical plans - things that employees need access to.
The chalk allergy is real but quite overstated. There are many people with reactions to the chemicals in whiteboard markers and the cleaner that many whiteboards require is even worse. I still see no mention of those, even though I've had problems with it myself.
That seems like it's going to be a tough sell seeing as it uses Dart instead of JS when JS devs already have React Native, NativeScript, Titanium and Cordova to choose from. But I'm a firm believer in a rising tide lifts all ships, so bring it on Google!
... still leaving you, after you subtracted SystemXVI because of the licence and launchd because of the XNU stuff that had to be ported to support it, with at least one BSD-licensed non-Mach replacement for rc.d already available.
Progress! Let's keep going.

I think you meant to say "That it is parasitic is factual if I make a bunch of assumptions about AVIS' profit margin and intent, as well as OP's past and future business dealings with AVIS. That hypothetical parasitism is immoral is my opinion."

As you get more practice making distinctions between what's true and what's opinion, I think you'll find it easier to interact with different viewpoints from your own :)
Most android developers have Java background. Dart fits better there.
I've never seen such a paper, but presumably it could include a date and serial number? If that doesn't match their records, TSA will know something's up.
> But if you have the foundation and know the native platform, why jump ship to JS at all?

I'm a (native) Android and JS developer. The primary reason I'm excited about React Native is that I don't have to go through the tedious compile-install cycle for every little UI change. React Native will make prototyping/iterating on Android as easy as it is on the web. However my reasoning assumes that there will be almost no friction in terms of creating complex views in React Native. I'm curious to see if that pans out.
You could maybe bootstrap it with a stackoverflow-like point system and by allowing people to ask questions across campuses. There's a lot to like about the Yammer strategy, but the key is (1) bootstrapping it (2) error checking and (3) dealing with the fact that 90% of student just cannot be bothered.

What would the super-over-achievers like in exchange for their effort? Job offers/interviews (companies like conscientious team players)? Bragging rights (a la stackOverflow)?
Oh, I didn't even notice that. I encounter that notation frequently enough, but it wasn't the one I was taught in high school. Kind of hard to do a web search for its origins. I tried and failed.
Engineering MeetUp – Sept. 18th – San Francisco
Happy Monday,

Minted is hosting their 3rd Engineering Meet Up on Friday, September 18th! Light bites and drinks will be served at 6:00pm with presentation starting at 6:30pm.

Tim Worsley, our Distinguished Engineer, will present an overview of what website scaling means, what some of the common bottlenecks are, and how to address them with Amazon Web Services. He will also give an overview of the Amazon Web Services being talked about, and how to use them well. The talk will focus mostly on eCommerce and social media startups, Q&A following the presentation.

About Tim: Tim spent the last five of his thirty years hacking at Amazon, including rolling out ap-northeast-1 for AWS. Preferring breadth over depth, he has worked in networking, security, e-commerce and even spent time developing thick client applications.

Please join us and RSVP at:http://www.meetup.com/Minted-Engineering-Meetup/events/225209027/
Congrats on shipping on schedule! My experience with React Native for iOS has been pretty pleasant so far given how young the libraries are. My main frustrations so far have been with the Navigator component (both the 'fully native' and the 'emulation native' versions) and some inconsistent documentation, though the latter I suspect is the result of rapid API changes. Pretty short learning curve, though, and the results have performed well, so I'd recommend anyone with moderate experience with React to check it out. Looking forward to diving in to the Android version soon.
As long as the resulting people don't think that graphs are charts, static typing is ceremony and functional programming means programming functionality - everything goes.
I drag a Nikon D3100 everywhere. I've had some amazing shots from that even though it's a cheap DSLR. 50mm Nikor DX lens keeps it light.

Even the best phones make a poor camera. Laggy, awful dynamic range, awful autofocus and unpredictable.
Chrome on my MBPr is also dying in a fire here. Chrome on OSX is known for extremely shitty performance because it usually (always?) switches acceleration off.

If chrome://gpu/ says hardware rasterization is disabled, set chrome://flags/#enable-gpu-rasterization to enabled.

Chrome on Windows also will disable acceleration by default if it detects both an Intel and either AMD or Nvidia chipset enabled at the same time, thinking its a hybrid solution (even when it's obviously not, such as an extremely common desktop i5/i7 + high end GPU setup).
Abstractions like these always target the least common denominator. But React has the "component" advantage so i'm not dismissing its usefulness. it's good for a category of projects.
F* reworked and released as v0.9.0
I have a (genuine) question about this, as I'm interested. What is the benefit to supporting so many ways to instantiate a File object:

val f = File("/User/johndoe/Documents")
val f1: File = file"/User/johndoe/Documents"
val f2: File = root / "User" / "johndoe" / "Documents"
val f3: File = home / "Documents"
val f4: File = new java.io.File("/User/johndoe/Documents")
val f5: File = "/User" / "johndoe" / "Documents"
val f6: File = "/User/johndoe/Documents".toFile
val f7: File = root / "User" / "johndoe" / "Documents" / "presentations" / `..`

Why not just the first one, and string interpolation/composition if you need 'root' or 'home' ?
Genetically I have a 50% chance of getting Parkinsons. My father was diagnosed earlier this year, and 2 of his 4 siblings already have it. There's a medical study being done on our family to try and identify the gene responsible, but we already know my cousins and I have a 50% chance. I'm not sure I'd even want to know whether it's 100% if they were able to do the tests. Not until there's a possible cure for it. Knowing won't change anything if I can't do anything about it. I guess I'm still in denial, trying to just ignore it away for now.

I just hope there's a cure by the time my children (6 and 3 now) get to my age, otherwise I'll advise them to think hard about having children and passing on the gene.
Most mathematicians would consider this a formal proof. Do you mean a computer-checkable proof?
