You can just start writing JS on an existing page to output components rendered by React.

Fair warning though, React is focused on rendering and initializing, so it doesn't come with a bunch of handy JS functions like YUI or jQuery. But you can use React & other JS libs together, as long as you're careful that the other JS lib doesn't change the markup of a React component (which would take it out of sync.)
Apple have made a point that a lot of their learning is done on the device itself - stuff like the keyboard and Google Now-esque "if you leave for home now it will take X hours" never leave the device as a conscious privacy decision even though it results in a slightly less intelligent product.
I may get downvoted for this, but I'm going to answer the question you asked directly from the context given.

If you have no knowledge/experience in databases, and you are solving a problem not yet at scale, the short (but possibly unsatisfying) answer is that it doesn't matter. I would encourage you to learn more about both non-relational and relational databases to guide your thinking for specific problems.

MongoDB is the most popular non-relational according to StackShare (http://stackshare.io/databases). Perhaps you want more of a database service on top of that though, in which case Firebase is easy/cheap to get started with.

At the end of the day, each has their advantages -- for example, non-relational can give you a flexible schema and very fast retrieval -- but until you have more constraints for the problem you're solving, it'll be hard to make an educated decision.
Lets also compare them for power, noise and size.

Linode offers the equivalent of a tiny, tiny subset of AWS. I haven't looked recently, but do they have something equivalent to SQS? Autoscaling groups? DynamoDB? SES? Cloudwatch?

If you are going to end up re-building AWS's services from scratch on top of what are essentially naked linux machines (or doing your integration work between services from many vendors), you are doing a huge amount of work that isn't necessary and will be a lot more expensive than that $20k/ month you could have been paying to Amazon.
In the beginning, the secret sauce of Uber was still its technology - being able to order a car on your phone, seeing where the nearby drivers are, not having to pull out cash or a credit card at the end. This made the experience much better than ordering a cab.

But as a reporter or editor you could choose to highlight the deaths of innocents such as children to raise moral outrage, generate click bait etc and yet they don't. There often is an implicit bias in the reporters and editors themselves. Whether malicious, that's another question.
I’m pretty sure I made a comment about this or a similar post linked here a few years ago, including some graphics cooked up in Photoshop explaining the problems with the examples, but I can’t find it at the moment, and can’t be bothered to make new demonstrations.

Suffice it to say: unfortunately the lightness (a.k.a. value) of the color stripes varies tremendously from one example to the other in this post, which makes this a basically worthless comparison, as in general lightness contrast dominates other visual effects. If you swapped the lightness (e.g. in CIELAB or CIECAM02 color space) from the left and right examples while leaving the hue/chroma the same, you’d get the opposite results inre what looks “good”, which would reveal this “Müller formula” to be bogus (or at any rate radically oversimplified).

More generally, I’ve never seen a convincing exposition of similar color preference effects backed by data collected in a scientific paper with reasonable study design. It’s always handwavey 19th century nonsense, sometimes with a handful of preferences expressed by a tiny sample of homogenous survey respondents tacked on the end. Bad examples are endemic to the pseudosciency-color-theory genre, because most people work with terrible color models which are only marginally relevant to human perception.

The key to making color schemes for graphic illustrations or data visualizations look good is to use enough contrast (especially lightness contrast) between intentionally separate shapes so that distinct elements don’t accidentally blend together. (Note that sometimes you want certain elements to have lower contrast, but that should be an intentional choice, made for some obvious reason.)
There are much easier ways to make positrons.
And this is hacker news how?
No, I think that their use of existing technology is exactly the heart of the issue. They claim to have made a breakthrough in how blood tests are conducted that allows them to run a large set of blood tests on a tiny fingerprick blood sample. An investigative journalist then reported that they're not using this technology at all, and all the tests they sell commercially are regular venous blood draws run through testing machines purchased from other companies.

If Theranos is not using their fingerprick blood testing technology, then they are not using their technology commercially at all. So if this is true, then they're a company that's been in business 11 years, has a massive valuation, and has not developed a commercially viable technology yet. It's as if a web search company like Google had been around 11 years, was worth >$1 billion, and then was found to be exclusively using and rebranding Microsoft's search technology instead. It's a scandal.

Theranos' valuation cannot be sustained anywhere near its current value simply by selling blood tests conducted on equipment manufactured by other firms. Theranos' claim to fame is a breakthrough in fingertip-prick blood testing technology, and they have no way to differentiate themselves in the market without this breakthrough technology - their investment value cannot be sustained simply by reselling technology made by other firms.
First sentence:

The world has come a long way since...

Would you say this use of the term `world` here fits a classical linear logic (Newtonian exclusive logic) guided English register, while a report that speaks from multiple cultures' points of view and has multiple interpretations would build on a modal logic (para/transconsistent, inclusive logic) guided language register[0]? If so, how might you translate or rewrite this report in other languages or other English registers, and how would you review its philosophical interpretation of "the human experience"?

TH is hard to debug. When you get an error message, you see the TH generated code, which can look very different from your source, and the line numbers are meaningless.

Most of the reasons to go with AWS as a major strategic decision are to avoid paying for 3-4 (or perhaps... 40+) ops engineers to run and manage so many things that really don't add much business value in themselves and that you could hold to some form of an SLA (especially with enterprise support accounts) and recoup some costs if things came down to it. Furthermore, engineering a lot of AWS services would cost you developer time as well.

I consult / contract for a Fortune 50 customer that pays an insane amount of money to AWS per month and it seems ridiculous what they're paying for and what they get. But do you know what's even more ridiculous? Paying three times as much but getting even worse reliability and a massive amount of time wasted while waiting weeks to provision servers. One group internally used to have massive outages daily resulting in needing to hire a dedicated team of about 6 just to handle that load of production incidents (terrible reliability also resulting in loss of revenue too) and since migrating their software with even the most bone-headed SPF-everywhere AWS based software architecture haven't had more than one or two per week for outages now. The cost benefits get better the more incompetent / incapable your internal IT organization is. The amount of wasted resources due to internal bureaucracy, legacy, and working with companies that don't really practice any form of technology at scale has been an incredible amount of savings for my customer.

And knowing how much my customer relies upon AWS support for the most menial of tasks (primarily a cultural thing with how they treat their vendors as well as internal resources) I am sure that nobody but massive companies that deal with external bureaucracies effectively could deliver the size and kind of support team to handle the volume of support requests generated by my customer for the most ridiculous of tasks (I've seen executives file AWS support requests to reboot VMs at 3 am because the bureaucracy is extremely brittle here and reflects into the software systems reliability). We may throw millions / month at AWS, but Amazon has to hire at least a few dozen engineers and several account managers just to handle support alone which I might argue could be a net loss to handle the customer.

Most vendors that work with my customer have a very hard time working with them because they approach sourcing quite similar to how Walmart does and abuses them to the point where the vendors abuse their employees.
This definitely reads like an ad for Linode to me and it really is turning me off from your company. Does the company know you are posting these comments on HN?
Whoa whoa, we're talking performance not cost. Want to compare cost and performance? Use a Leon4 Quad-Core SOC on same process node so both are embedded. Otherwise, we're comparing RISC embedded on advanced node to SPARC servers on old nodes.
At the very least, eat healthy, exercise regularly, and sleep well. Hard to break out of a rut without it.
Agreed. Neither Facebook nor YouTube run without JS enabled, which means that the vast majority of your users will never even consider turning it off.

FWIW, I'm a current Linode customer that will be migrating to AWS soon. I like Linode as a basic provider, but I really need the better features such as ASGs, AMIs, and RDS. That's worth the higher cost per hour for me.
Especially the Leon3 and Leon4 embedded ones. Throw in cost of processor license: up to $15 mil with royalties for ARM ISA vs $99 for SPARC ISA with implememtation a fraction of ARM's.

> Table 4. Correlations between Appearance Ratings of DragonCon Photographs and Self-Esteem, Narcissism, and Geek Engagement.

So, I haven't* read the entire paper, just skimmed it; but it seems to me that what they're saying is that those geeks who are likely to have their photograph taken at Dragon*Con, are more likely to be narcissists.

That looks as if they are selecting for a subset of geek culture that is more likely to contain narcissists, and then stating that the results are representative of the entirety of geek culture.

Side Note/Related Note: 'Geek Culture', is not relegated to conventions, and in many ways it lies outside it -- Reading, knowledge-gathering, etc. are largely introverted activities; and geek culture itself grew up around early - mid 20th century Science Fiction and Fantasy. So I find it difficult to understand how they could claim that the subset of geeks who visit conventions is representative of the entirety of geek culture in the first place.

A better comparison would be if Uber had claimed they had self-driving car before they'd even entered the market, had started doing rides, and then it turned out Lyft drivers were surreptitiously hidden inside the front of the car and were actually driving instead of the mystical self-driving computer.

That's how it looks at the moment with the way Theranos is behaving.

A lot goes into processor performance besides clocks. Pipelines, caches, memory bandwith, timing of individual instructions... even the compiler version on same compiler. So, go ahead and give the junker a spin to see how it compares. Might surprise you.
Is this something innovative? In india, i just paid 90$ and got 14 different tests including tumor markers tested for. The blood was collected at home (and then sent to a central testing facility).

Unless, it is radically new technology... I'm curious on the value proposition here.
I was going to say the same thing. The amount of transparency in general from aws is DRAMATICALLY better than linode.
Right now the scanning works well for a limited number of scenarios (such as the ones shown on the page). We are working on improving the quality and expect it will grow over time to cover more and more cases.

Unlike Kinect this is a passive sensor technology which has it's own advantages (it works outside) and disadvantages (it does not work on completely textureless areas).
I think "king of the web" is gonna look a lot different in the future than it does today and did in the past. JavaScript will be, for the foreseeable future, the king of the web front end, and I suspect it'll also hold a strong role on the back end. It may even be unstoppable on both ends because of the incredible resources being thrown at it.

However, systems management, deployment, provisioning, data aggregation, log/event analysis, etc. on a large scale becomes more important by the day, and if there is an area where Perl is still quite popular, it is in those back end tasks. There are trendy tools in newer languages, but you'd be hard press to find very large deployments (at least on Linux or other UNIX) without a few hundred thousand lines of Perl running some elements.

Perl 6 with concurrency built-in, grammars and the most advanced regular expression engine in the world, seems very well-suited for that future. Being somewhat familiar for old school sysadmins who've always relied on Perl for their scripting tasks is a bonus (Python has made some inroads in that space in recent years, particularly with Red Hat and Ubuntu/Debian shipping many system utilities that are written in Python).

Anyway, on the web front, I think we need a reasonable database abstraction layer (e.g. Perl DBI/DBD), at the very least, before it gets elevated to "always available" on hosting providers. I'd say give it another year, and we'll have a pretty good Perl 6 web development ecosystem to work with.

I agree that those other things are stronger evidence, but I think the stuff I cited is still a significant, independent strike against Theranos.

Correct me if I'm wrong here, but in a negative PR storm, isn't it a godsend when people (especially journalists) are actually trying out your product for themselves rather than joining the bandwagon based on innuendo? Why would they be turning away people from trying the one technology they (still) hype the heck out of on their website?

And why would the communications director be getting names of patients (point 4)? Passing private medical information over to a PR agent is really shady and an abuse of trust.

mozumder -- um... what?

But, here is an answer - 10,000 requests per second is 100 microseconds per request. At 100Mbps network speed, this gives (roughly) 10 characters per microsecond or a budget of 1,000 characters combined per request. We will take 100 characters for the request, and 900 characters for the reply. Of course, you could go with 1Gps network service, and multiply this by 10. But, you will need at least 20kpps "per core".

However, you also have to contend with disk i/o and/or the database layer.

Which OS? I think you are probably a long way from being able to answer that question. Note that OpenBSD will not be as "multicore performant" but that may not matter in your application.

Yes. There will always be a less stupid solution out there that is not as bad as the bad solution.

Perl 6's semantics are so different from Perl 5 it should effectively be a new language. It has metaprogramming macros like CL, concurrency that's as well thought out as Erlang/OTP, they eliminated all of the syntax warts that Perl 5 had with all the implicit magic, and out-of-the-box is absolutely fantastic with rules/grammars that I'd argue it's about as good as Haskell's Parsec. (Speaking of Haskell, I've seen some code that's written in a purely functional Haskell-ish fashion in idiomatic Perl 6.) Oh and there's finally a good object system instead of stop-gapping with Moose (which actually was kind of fun, meta-object programming was cobbled on, but I digress).

The take away - don't conflate it with your 1995 Perl. It's about as similar to Perl 5 as C#1 (pre-generics, pre-LINQ, pre-RX, pre-async, pre-NuGet, pre-basically-everything-good) is to modern C#.
Some people define success as something entirely exclusive of your bank account.
I thought that way until I worked with iPython for a while (back when it was primarily a clever REPL, and didn't really have the "notebooks" feature at all, yet, I don't think...this was back when it was new). Having a really strong REPL when debugging is like having a rocket, when you're used to having a hot air balloon.

I've always been bothered by the weakness of Perl REPLs. It's only recently started to improve (in the past five years or so) for Perl 5, but there are some decent ones, though nothing even in the same league as iPython.
I don't agree that this is schadenfreude.

Here was a company that popped up, literally out of nowhere, claiming to have a handle on microfluidic diagnostic assays...something that the major players in the industry haven't been able to get off the ground since ELISA came along in the 1960s.

The skeptics were quiet at first. I mean shit, they landed Walgreen's and Kroeger! It must work, right?

Now we discover a little more of the truth and it's a lot safer to say "put up or shut up".

It is true that whenever you add an abstraction layer, you sometimes lose a little bit of control. That being said, there shouldn't be very many technical limitations imposed by GlueStick that would block you when you get 90% with your project.
