> Stock can't have negative value.

A component of a business can. Ignoring the problems that make marginal stock prices problematic for overall valuation, and transaction costs, etc., the stock price of a corporation should be max(0,sum(value of all components of the business)). The fact that this value should never be less than zero doesn't mean that no component of the business has a negative contribution.

It looks like there have been already quite a few discussions among Wikipedia editors about this article (it's quite interesting to follow the comments chronologically).

The main criticism I see is that the suggested article sounded like advertisement with links that only serve PR.
It absolutely does! Let me know what you think at manisha@shippable.com
I'd be interested to see how much faster this is than drone.io. I get pretty fast builds on there. It's also built on Docker, but I don't think the images are saved after builds (so dependencies and whatnot aren't cached).

I'd also be interested to know how Shippable knows when to remove a layer to update dependencies.
Apparently management was actually mildly annoyed that Grasshopper team didn't break one, as that suggests they weren't pushing it hard enough. I think it may have been more "tongue in cheek annoyed" though.
> Their focus has raised them to prominence, having recently surpassed Amazon AWS in the number of web-facing computers, according to Netcraft

You misread that article. They had a larger single-month gain than AWS in web-facing computers. They are not larger than Amazon.

> The company operates datacenters in New York, Amsterdam, San Francisco, and Singapore.

They do not operate any data centers. They have servers in other companies' data centers in those locations.

The rest of the article is written like an ad. It's missing any claim of significance -- what makes DO different from the other hundreds of small VPS providers? Wikipedia isn't a company directory, significance is a requirement for having its own page.
> DO is well-known on HN, but I don't know anyone else who's ever heard of it.

IMHO that's a pretty good reason to give them an article. I've heard the name, but I don't know what they do or what's their specialty. If I wanted to get information on them I would be looking on Wikipedia (besides their website, but companies' websites are often full of marketing speak so I usually go to a third party).

Usually, you pay a premium for large equity stakes, because they come with more practical control. (Witness every tender offer takeover ever.) The other two points are more convincing, however.
That's the media for you, and not necessarily "Fox" or whatever x-wing group you seem to dislike. Fox news is only seen as "bad" because it doesn't exaggerate reality to the side that the majority like. The other news media outlets do the exact same thing, just towards the other side of the narrative.

Both sides of the media play on peoples' emotions. The real question is: are you intellectually honest enough to entertain views and thoughts for their own merit without dismissing them flatly just because "they're from Fox", "John Stossel", or "Romney".

> having channels doesn't have anything to do with Reactive Programming

Mostly agree, in the sens that, from my limited pratical experience & knowledge of Reactive Programming (RP), I understand that RP isn't bound to a particular "parallel execution model" (maybe s/parallel execution model/threading model/ ?).

> There is a very long thread on the Go list of a guy who is a fan of dataflow grumbling about how design decisions made in Go make it a poor fit for dataflow.

I can't find it in https://groups.google.com/forum/#!searchin/Golang-nuts/React...

A blog post might be better fit for that (so far I was unsuccessful getting constructive feedback that way). Anyway here are more thought, based on my experience dealing with GUI app:

- "parallelism", even if simpler with an event-loop, is still a significant burden especially when performance matters

- Class based OOP, especially not JavaScript, is very helpful to group a sequence of callbacks to help fight spaghetti code.

- Explicit State Machines are a praised black art wrongfully dubbed useless overhead because "it's possible to do otherwise"

- «yield/await/async» as been recently recognized broadly as the way forward cf. https://news.ycombinator.com/item?id=4732924

All the points mentionned above have in common that they try to handle correctly with fine grained priority and different "paralellism" patterns with ease.

RP mean to provide much more than "yield", it's pattern that is similar to the explicit state machine intent. The declarative paradigm/syntax arguably provides an ease of use that is competitive both in terms of performance and dev efforts even if mileage may vary. See by yourself:

>>> HackerNewsPost.rank = HackerNews.upvote_count * MAGIC_NUMBER

This one might be better expressing the actual behavior, even if the ranking algorithm is "hidden":

>>> HackerNewsPost.on_change(HackerNewsPost.position).update(HackerNewsPost.rank).maximum_frequency(timedelta(seconds=60*60))

The above can not be expressed in "one line" using "yield" and whatnot.

Good point. There are federal rules in place to address that very issue, as a direct result of the outbreak you mention: http://water.epa.gov/lawsregs/rulesregs/sdwa/lt2/index.cfm

Essentially, the options are cover your reservoirs or put filtration & disinfection systems in place.
I have to agree with the deleter that called it "G11: Unambiguous advertising or promotion".

Suggestion: Cut out all the adjectives and stick to a 'just the facts' style. Find an article that isn't about DO's finances but instead just lists it aside other major cloud/VPS providers.

Now that is not very interesting. "Growing faster than Amazon" could become interesting if it is sustained, hut as pointed out elsewhere they are tiny. Wikipedia is not a cloud server hosting comparison site, there are plenty of those that can be much more useful. They have not produced any interesting software or anything else innovative, and their only point of note is being cheap and advertising a lot on twitter. There are vast numbers of cloud provision companies, and this article has not convinced me that right now this one is sufficiently interesting that anything else other than what is written above could ever be written, unless something else happens. Certainly the VCs no doubt hope they will become more interesting over time.
Oh man! I only wrote one program ever that could be used for malicious intent if so desired, and that was a GetAsyncKeyState()-based keylogger. Simple to write and so cool. The toughest part was figuring out how to register itself as a windows service and give it a good name so most people would ignore it. I ended up making a separate executable for that.

Anyway, I got curious to see how my coding style had evolved since I was a kid so I dug it up for all to see: https://gist.github.com/aktau/11057438 (I was young, be gentle).

> RAII is superior to this approach:

unique_ptr is not RAII now?

> 1. Easier to read

That's debatable, here ``make_resource`` has to be understood once and will thereafter work with any C constructor/destructor pair. Considering the tone of your comment I guess you mean wrapping each pair in its own object so each of these wrapper objects (and its ownership semantics) has to be understood, and at a fundamental level they're redundant with unique_ptr.

If you don't like the generic thingy and want one wrapper object per call pair, you can just typedef the unique_ptr.

> 2. Easier to use

Easier to use than calling a function and having a unique_ptr with clear ownership semantics?

Twitter had something like $300M revenues[0] at it's IPO and, based on the opening share price, was valued at $14B[1]. That's 46x.

Still seems crazy high, but seemingly not out of line with other recent tech valuation multipliers. There are some other insights in these comments that seek to better explain the valuation.

I would only need to raise my average APR by about 0.2% to cover the PayPal fee. Interestingly Kiva gets around this: "Kiva is the first organization that PayPal has supported by providing free payment processing. This support saves Kiva up to one million dollars each year, which helps us to keep our operational expenses low and send 100% of your loan contributions to the field." The CEO of Kiva is formerly from PayPal. This is a serious advantage to Kiva, and disadvantage to Zidisha. I have no idea if there is an alternative way of uploading funds to Zidisha without incurring these fees.

Regarding my profit motive, I don't see these platforms as an effective means to profit. I seek to break-even. By seeking to break-even this permits side-by-side comparisen. It creates a level playing field to compare, and from this, one can modify the break-even criteria to measure the impact. For example, on MyC4, if I see a loan is fully-funded at 12.2%, but the interest ceiling is 12%, I have a simple Excel tool that tells me how much I need to bid at 5%, or 0%, in order to displace enough of the highest-cost bidders in order to faciliate the loan. So, I might do a modest loan of only $25, at a very low or zero interest rate, but as a result of this a loan for $500 which may not have otherwise been disbursed is able to be disbursed. I consider this a good use of my funds. Also, by constantly displacing the highest bidders, at the margin this may frustrate them by constantly having their bids removed at the last minute, and persuade them to lower the rates they charge - who knows if this is effective or not, but this is one strategy I use. But, overall I seek to break-even on all these platforms.

This is not entirely altruistic. I also have a one-year fixed-term deposit at a regulated microfinance bank that I know very well, which yields 8% APR and suffers no forex risk. My funds are also used for lending to microfinance clients, only I don't know precisely which ones. My logic is that this generates a relatively risk-free return (the credit risk is with the bank itself, not the individual clients), and means that if I break-even, or take a few hits on my P2P lending, then in the long-run this all cancels out, and I might cover inflation hopefully. Such fixed-term deposits might be considered an alternative mechanism for microfinance lending, but it is relatively undiscovered in the mainstream retail sector, also invovles transaction costs, and requires more paperwork to set up. And of course, it doesn't harness the feeling (imaginary or otherwise) of P2P lending.

That was the total number of hosts they had in June when Netcraft wrote that "meteoric rise of DO" article, which is what I assumed the talk page was referring to as a citation. Proving notability for Wikipedia generally means linking to news articles like this.

I don't think pmarca/tptacek mean the price would be lower if someone were buying 1,000,000 shares all at once. Rather, if AirBNB tried to sell 1 share, it would naturally go to the person willing to bid the most for it, and that price would be higher than the average selling price if 1,000,000 shares were released.
By standards I also mean the notability standard. Being a business that's doing well is not enough.

How does one do testing on OSx without having to buy different machines.

Not sure what point you're trying to make here, but I was responding to your post implying that 192kHz sampling rate improves transient response. It doesn't improve it at all. While there is sampling "distortion" by way of quantization error, this error is inaudible because we're sampling at 24 bits, beyond the dynamic range of human hearing. High sample rates actually REDUCE audio quality because they sample ultrasonics that will interact within the audible range and potentially damage speakers or pick up EMI interference.

It has been proven over and over via ABX testing that high res formats are completely indistinguishable from a 24b/44.1kHz master. And further studies have proven most audio engineers can't distinguish between lossless audio and 320kbps MP3. That's what the Xiph link elsewhere in the thread shows.

The moonshot is human blood/tissue mRNA sequencing with a 30 minute turnaround for under $100.

That requires some insane processing locally to create a gene expression histogram, a secure cloud database to match against other patient data to recommend health markers, and a few terabytes locally of other gene combinations that are known dissease markers to sift through.

AIDS, diabetes, cancer, ... any disease detectable by your gene expression levels being out of whack can be diagnosed.

If only. That would be a great form of funding community governance. Where local communities help themselves up, instead of practically begging for scraps from a wealthy government that really doesn't care until it gets them votes.

Change has to come from within. And it won't come so long as people think like you. i.e. "Change can come when funding comes from better places" Which completely ignores the real problems and real difficulties facing real people in those places you seem to not want to live in. Ask yourself why you don't want to live there.

This is no worse than anything else in the standard library. Writing generic template code is always ugly but once written you don't have to deal with the ugliness to use the resulting functions. It's not worth the complexity in most cases but if it's something general you're going to use a lot (and lots of C libraries have this idiom of Resource_Init Resource_Destroy function pairs) then it can be worthwhile.

Eigen is a quintessential example. It's some of the most complex and inscrutable template code out there but it makes writing numerical code in C++ almost as nice as matlab while also being extremely fast.
I think you're stating their point accurately. But what I mean is that in the usual case, the value of 1,000,000 shares is actually greater than 1,000,000 x (price of one share), because you're getting something more with those million shares: control. That said, there may be countervailing forces at work in tightly-held startups that don't apply to liquid capital markets.

I'm arguing for introducing thin abstractions over the underlying API to handle lifetime issues, and encapsulate icky, SDL-specific details and types as they arise.

They are definitely redundant with unique_ptr. In return, they're higher-level and more abstract. It's up to the developer to select what level they need to be at. I favor abstraction and readability, others may not.
