In fairness, 4 socket servers are pretty serious money. Just the difference in cost for 4 socket capable Xeons alone puts them out of reach for many use cases.

E5-2658 v2 (dual cpu): $1440 per part
E5-4650 v2 (quad cpu): $3616 per part

As a result, I stick to 2 socket servers for Linux machines. I think the scaling out paradigm just works out a lot better, particularly for Internet services.
I have come across a startup founder who drives Uber in the evenings to help with cashflow.
But he is a unique subset as well. His family lives back in South Africa and this keeps him occupied in the evenings plus he can do a bit of customer validation if occasion presents.
This too is an issue that medical advice to friends and family regarding suicide covers explicitly: to wit: do not commit yourself to confidences regarding suicidal impulses. You may need to break those confidences to ensure the safety of those you care about, and the commitments may harm your own judgement about your best course of action.

There are a variety of things you can do before calling 911; "call an ambulance NOW" is not the message I am trying to send.

If you're someone I know well enough to judge the credibility of a plan to kill yourself (which could mean "complete stranger" is the plan is particularly credible), and I become aware of such a plan, I would feel obligated to ensure you saw a doctor, with the word "ensure" chosen carefully.

At this point I feel like I'm replying to comments on these threads more out of habit and standard message board compulsions than anything else, and, given that the topic we're discussing is sensitive, I'm going to force myself out of the thread now.
Man, learn to pick the right fight with the right person.
In reality, the exact opposite is happening. In the U.S., wealth concentration is growing with the top 0.1%.
Whoa. That's heavy.

The beaker, I mean. That must have been a very heavy beaker of solution!
Agreed. I had a hackintosh for a year and something always freaking broke or it wouldn't boot up.
This is one of the exotic devices in DARPA's UPSIDE competition for exascale computing. This initiative seeks to find non-state (non-transistor) based approaches to computation: exploitation of nanoscale response properties of discrete components to perform some restricted, non-binary, forms of computation. Essentially, exotic ways to abuse silicon lithography to get analog computation.

The idea, and this can be seen on DARPA's slides (http://www.darpa.mil/workarea/downloadasset.aspx?id=21474857...), is to get computation that is several orders of magnitude higher for their specialized sets of problems than what can theoretically be reached by traditional computing models even if Moore's law continues.

DARPA would like to first apply this technology to ARGUS drone systems (https://www.youtube.com/watch?v=QGxNyaXfJsA) and related technology because streaming video can't be done to the ground, tracking and decision making must be done on board - yet traditional processing platforms can only track a few orders of magnitude fewer targets that what the military would like.

In a more advanced phase, if memristor or coupled oscillator (etc) approaches to building inference models become possible, then programs written in DARPA's other initiative (Probablistic Programming) could be programmed into these exotic solid state devices to compute in a way more analogous to today's generic computation. And indeed, eventually the adoption of Probablistic Programming will train programmers to write code for quantum computers - while more complicated, replacing Probablistic Programming's PDFs with probability amplitudes almost get one there.

I hope to see more journalistic coverage of some of the other exotic devices.
While I wouldn't go so far as agree that it's a strong argument for communism (though I do support guaranteed, unconditional basic income myself), I do think it's a strong argument for broad public education initiatives...imagine if there was a required class called "How To Tell When a Politician/Company is Bullshitting You." Seriously, no sarcasm, I think that's an extraordinarily useful skill that is often glossed over, and if someone made a curriculum for understanding psychological biases, that could prove insanely useful at mitigating the effectiveness of these ploys.

I don't intend to shift any blame here. The feedback link isn't a solution. I know you can't un-see docs and reclaim your lost time.

But, there are a lot of words in there for us to fix, and that feedback does help us prioritize :)

The belief in perpetual growth is a cultural malady.

But you're right, no startup ever said that!
Does anybody have an idea on how long dissolving a piece of gold that long would take? The article says it's a very slow task, yet makes it seem as if Niels Bohr was able to do it in minutes (or a little longer).

E.g., "...physicist Niels Bohr has just hours, maybe minutes, to make two Nobel Prize medals disappear."
People tout the public ledger as a benefit of the block chain, but it's utterly useless as soon as someone converts to another currency and then back again (a.k.a. Tumbling).

What is probabilistic programming? – The PL Enthusiast
You may believe this. I may misunderstand you.

But statements like this are one of the reasons people are reluctant to get help. My problem is bullshit. I'm weak. What will people think?

Regardless of whether the "reasons" or problems are real (to you) or imagined bullshit, people do kill themselves over it.

Don't perpetuate an environment that discourages people from getting help. They're already not thinking rationally.

Which do you think will produce more survivors and thrivers:

"You're problems are probably bullshit."

"You should talk to a professional."

Let the professional decide if it's bullshit or not, and lead the person to the right treatment.

EDIT: removed swearing.
Texting Base Launches New Personalized Marketing Automation Platform
So this is my big announcement…many of you are right. As of right now, Texting Base is officially launched! For those who don’t like to read, that’s it! Click on the link and see why it took so damn long and let me know what you think. Accounts are free. No credit card needed.

For those who like stories of craziness feel free to read on.

3 years and 3 months ago, I did one of the craziest things a human being can do…I started a software company with no money. This might be an OK idea if I were a programmer but is absolutely insane if a person is NOT a programmer. I am not a programmer.

No one had built a “group texting” platform for businesses where no matter how many people were in the group, each recipient got their own personal message that they could respond to.

Through a series of miracles that have made me reevaluate my place in the Universe and the existence of a higher power, I am pleased to announce Texting Base is finally out the door.

Without putting in your credit card, you can:

-	Create an account

-	Access the system

-	Upload contacts

-	Create groups

-	Evaluate whether I am crazy or onto something

This is a business tool. Individuals can use it, but please don’t tell individuals about it…I don’t want to have to deal with anyone I don’t know unless they are a larger user. If I try to support 10,000 individuals by myself, I will have a heart attack in 6 months.

My heart and soul went into a piece of software that I know for a fact will make lives better, save people time and make people money. I don’t want anyone pressured to sign up. Selling this is not my concern. I would like people to take a look at the product, provide feedback and refer anyone they think could use this product.
I theorize that it's because they're server grade equipment, and the used market for server gear is not that large. Most established businesses don't want to risk buying something that straight up doesn't work or will fail later, even at a 50-75% cost benefit. It just isn't worth the time spent dealing with it.

If you're a one person startup, then you do what you have to do to survive. Eventually you get to the point where free stuff actually costs you more than just paying for it in the first place.
> If you're someone I know well enough to judge the credibility of a plan to kill yourself (which could mean "complete stranger" is the plan is particularly credible), and I become aware of such a plan, I would feel obligated to ensure you saw a doctor, with the word "ensure" chosen carefully.

The scenario I am describing to you is one in which I was seeing a doctor, regularly (once a week). I was already getting help. The only assistance I was not getting was inpatient, take-your-rights-away-for-a-while forceable assistance.
I ended up reading the article in Print Preview. No way for them to screw that up.

Funny, I came to the comments to say the same. Segmented sleep is a theory all from writings of a "second sleep". I imagine for some small groups this may have existed but seems extremely unlikely as a normal behavior.

BBC went as far as to write "The Myth of the 8 hour sleep"
http://www.bbc.com/news/magazine-16964783 without citing any anthropologist or medical insight.

I imagine however, prior to modern society, humans took naps more often, especially in agrarian societies after particularly laborious days.
I used to think Safari “Reader View” was sort of daft but I’ve been indispensable lately…
so if i read this correctly "This filter will not work for tests that utilise classes via interfaces, reflection or other methods where the dependencies between classes cannot be determined from the byte code."

if you are using interfaces to inject and mock things, it cannot test your code?

this sounds really cool, but most of the stuff we do is down with interfaces...
It is appealing in a way, but I also think it would put the business at legal risk in a way that is totally unconscionable. We cannot run a Hackintosh in production for a single moment, the long term ramifications could be immense.

The chassis we designed represents my attempt to re-house the Mac Pros in something more suitable for the datacenter.
The table flip is more about whimsy than effectiveness. :) Given many options, I usually pick the one that's most fun.

Honestly, I plan to read all of the feedback. I worked on the Firebase docs, and I've see how effective a tight feedback loop can be for improving polish.
I wonder what the yield was. How much mass was lost between the original medals and the recreated medals?
I'm glad it wasn't just me, but I had this happen with (what I think is) another site earlier. Are you guys using Ghostery too, perhaps?
Yeah, I've had a number of WWB/DWB stops, and in one case a cop pointed a gun at me and forced me to the ground. My crime, jogging in the majority white neighborhood I lived in (there was no active crime in progress, the cop decided that I was 'suspicious' and even after finding nothing on me (I was dressed in sneakers, shorts, t shirt since I was you know, jogging) he proceeded to run my license multiple times and ask me repeatedly what I was doing in the area (apparently 'I live here' and 'jogging' were not satisfactory answers). In the end I got my license thrown back at me with a sarcastic 'have a nice day'.

I have had very few police interactions where it was not clear that the cops viewed their role as dominating and using overwhelming force. U.S cops seem to have a very militaristic mindset which is really bizarre, considering compared to other jobs, being a cop is not that dangerous.In fact, the one case that stood out to me was one where a cop acted the way he should have. I got rear-ended on New Years Eve (as luck would have it, right in front of the State Trooper Barracks). The State Trooper who responded was amazing. He checked on everyone, found that the passenger of the idiot who rear ended me had a broken nose (she had no seatbelt on), called an ambulance, squared everything. He had a truly calming presence. That is how cops should be.
I think that line was written for dramatic purposes to indicate that he didn't know how long it would take for the Nazis to show up so he had to be as quick as possible. It doesn't necessarily imply that it didn't take him hours and hours. (But I've no idea what the answer to your question is.)
Road Rage at its FINEST
While broadly I have to
agree with much of what Fred
said there, I do have some
qualifications.

At the end Fred did mention
family, etc. Here he was way
too weak: A recent phrase is
"The greatest prize life has to
offer", and that's husband and
wife, house and home,
mother and father, with
everyone busy, productive, and, thus,
happy.

"Thus happy"? One of the standard
ways to be unhappy is to be idle,
doing nothing. One of the best ways
to be happy is to be busy and productive.

All that said, I have three points
of qualification:

(1) It can be a bit self-serving
for a venture partner to
tell everyone else, especially
entrepreneurs, that they should
not think too much about valuation.

(2) I have wondered if the recent
late stage equity fundings with
high valuations have a dark side:
Maybe the end of that little
process over time stands on average to
favor the
venture firm: If (A) the
company does not do really well, then
the venture firm still stands to
get their money back via the
term sheet liquidation preferences.
And (B) if the company does do well,
then the high valuation might be
seen as a starting point for negotiations
with the investment bankers on
the offering price of the IPO
or an M&A exit
in which case the venture firm
not only gets their money back
but makes a bundle (big ROI).

(3) As has become more common recently
in the press on startups, now
the way may be clear for
some significant number of
solo entrepreneurs with little
or no equity funding
to create a company worth
$1 billion just from
net present value of
after tax earnings
in which case all the
discussion about equity
funding is next to moot.

The common example is the
Canadian
romantic match making site
Plenty of Fish which was
long just one guy, two
old Dell servers, and
revenue of $10 million a year
just from ads via Google.
So, that's about $10 million
a year pre-tax earnings
and, thus, maybe, a company
worth $1 billion.

I know; I know:
From none other than
John Doerr at KPCB,
"Ideas are easy and worthless.
Execution is everything.".
Hmm ...: Given an idea,
now plug together a development
computer, install a lot of free
infrastructure software,
use some frameworks, etc. to
write the routine software,
write the rest, the
secret sauce, as just
ordinary code,
plug together a server,
plug into an ISP,
get ads from ad servers on-line,
use a content distribution
network (CDN) to handle
much of the Internet traffic,
go live, get some revenue
and earnings,
maybe expand to a local
colocation site or to
the cloud, and grow.

So, where's this
execution that is
not routine!

Or, for such a scenario,
given a good idea, the
rest is routine. Then
the idea and associated
secret sauce are
"everything"
and likely challenging.

Or, for a venture partner to
claim that ideas are worthless
looks like an initial negotiating
position to claim that what the
entrepreneur has before a
term sheet is worthless.

Cute. Silly, insulting,
dysfunctional, but cute.
USB keyboards can get around the ten key limitation by presenting themselves as multiple devices.
I see where you're coming from. Hopefully I can defend some some of the researchers in that field :)

Although most applications of that research are often applied to business and marketing, the underlying research has broader implications. For example, some of those studies progressed our understanding of cognition in general (the researchers merely used numbers in their study - which was then adapted for pricing applications). But we now understand more about our brain's processes than we did before.

And ,with a better understanding of cognition, we can help pave the way toward other, more benevolent applications (e.g., curing psychological ailments).

So even though that research may not produce benevolent results directly, I would argue that it helps indirectly (among many other benefits too).

So that's my two cents.
"This was not an obvious solution"
1) Are you a sleep researcher? Links to research?
2) Do you have ANY proof/citations to back your claim?
3) To call ANYTHING in history 'utter bullshit' and 'never existed' is the kind of BOLD CLAIM that professional historians are known to undertake only with a large background of research behind them. Do you have the extraordinary backing for your extraordinary claims?
4) You call humanity stupid. Considering 1, 2, and 3, would you consider toning down the language? EVEN IF you had ALL THE EVIDENCE IN THE WORLD to support you, that would sound mean. Considering you present none, would you agree with the assessment this is an unnecessarily arrogant and 'negative' comment that really doesn't deserve to be in this otherwise generally respectful and civilized forum?

edit: spelling.
Yeah, the legal risk just isn't worth it.

It'd be interesting to see someone rip apart a Mac Pro and build an entire form-factor around its setup.

Don't get me wrong, what you guys have done is extremely beautiful in all ways, but I can't help to think that if someone wanted to do this with say a Mini... say you take a 1u rack, drill some new holes into it... hmm.
To counter ghosting over USB? They use a different protocol than the HID keyboard protocol. If you're not constrained by that protocol, you can send as many key combinations as your keyboard is capable of generating.

Of course, this means that you need custom keyboard drivers, either installed via a package or by default, and the keyboard needs to be capable of switching protocols, based on if its talking to a OS with compatible drivers or a BIOS without.
RoboVM 1.2 released
This has got to be one of the most impressive things I've ever seen. In fullscreen mode, it just brings the late 90's back.
That is one of my biggest concerns. A lot of the new tools are just different, not better. But you're expected to know all of them.

It's also hard to predict what will be popular five years from now. I thought that using Javascript on the server was pants-on-head retarded, but it's very popular, with no signs of passing on.
It's the development process that Google needs to fix. Google's development process does not require accurate documentation prior to release.
Apple supports Intel, AMD, and NVidia GPUs. Their graphics pipeline has over the years supported substantially all of the graphics chips produced by those vendors in the past 10-15 years. Their current full feature set may only be supported on GPUs that admit an OpenCL implementation, but that's still every bit as broad as the generic desktop computer GPU market—about two microarchitecture per vendor. Apple's not getting any optimization benefits from a narrow pool of hardware, for GPUs or anything else. The only benefit they get along the lines of narrow hardware support is that they don't have to deal with all the various motherboard firmware bugs from dozens of OEMs.
The Ad Injection Economy
Theres only one way to find out - win a nobel prize and dissolve it.
You're being overly rude about this but I agree on the point you're trying to get across. Most of the taxis I've been in were also drove by people trying to support their family. They probably have a better salary and maybe even compensations. Uber is certainly not disruptor in the worker rights zone.
It's still just a fantasy price if you can't actually sell your shares at that price.
Nick, this is extremely impressive and I applaud you for putting this together so concisely. Some comments:

1. Kahneman and Ariely both mention in their writings how their is a difference between free and even just 1 penny. Especially given how popular Freemium is I thought this might be a good topic for you to cover. (Ariely calls this "market norms" vs "social norms")

2. A common theme here on HN (mainly from people like Patio) is to "charge higher". I couldn't find a place that explicitly mentioned this. Many people perceive higher quality and value of products and services simply because they cost more (regardless of whether they actually do or not)

3. No mention of Kahneman?!?

This is awesome regardless...saving it and sharing it with some clients.

Feel free to contact me directly if you want me to elaborate on any of this.

How is this different then PayPal Credit (formerly billmelater)?
Though I don't know any more details about the events that took place, there are several ways of speeding up the process. As 23kt gold is quite soft, it would be a quite straightforward process to finely divide it and thereby increase the reaction surface area. Additionally, you could (gently!) heat the solution, though at the cost of a more copious amount of nasty fumes.

The Minis are incredibly simple machines inside, and their airflow is not great. You could pop their logic boards out and run them without the chassis. With some thought it wouldn't be too tough to significantly improve their airflow for this environment.

I do have an existing rack design that holds 64 of them (and other people have gone denser, with operational compromises I prefer not to make), so there's no great impetus on my side to rip them out of their enclosures.
