E-Gold™ is back.[0] Now with added cryptocurrency.

Having a blockchain registry to track ownership of precious metals is not a bad idea. But as the ultimate capitalists over at ZeroHedge [1] point out it's a centralized system and vulnerable to both fraud and attacks from governments ( vaults full of gold are hard to hide and harder to move ).

You're literally describing what microaggressions are: Small interactions, any one of which is harmless and without ill intent, which accumulate over the course of the day, week, or lifetime as an atmosphere of pervasive discrimination which is completely invisible to those responsible for creating it.

Microaggressions are insidious precisely because they're so innocuous; they let well-intentioned people participate unwittingly in systemic oppression that they would never consciously support.

If you're noticing yourself get a bit defensive about this idea, forget the word itself and just frame it like this:

You're a well-meaning person, and you want to avoid causing unnecessary harm with your words. So when you're around people who have really different life experiences than you, how do you make sure you don't cause harm without meaning to?

Economics. Most people are going to be offering you conventional cash so if you insist on paying in gold at face value then you've lowered the book value of your expenses. If you offer massive discounts contingent on being paid in $50 gold coins then yeah theoretically you could lower your taxes but a) you'd probably get audited sooner or later because other people are going to have to buy the coins and will then try to claim the market rather than face value as expenses, so there will be a steadily increasing imbalance between what they want to write off and the amount of income you want to declare, which will eventually send up a red flag. Also, if you pay bills at the face value then you'll be short-changing yourself to no good purpose, so you're going to want to sell coins regularly anyway and will become liable for the taxes when you do.
Scanning through the content (going from slide 5 to slide 20) is far faster with scrolling, at least with Apple's trackpad and OS X's scrolling inertia. Maybe it doesn't work as well on other devices.

But it is useful to walk through each slide with a keypress, so I'll probably add that feature as well. I want both.
> Crypto is hard, but it's no harder than a lot of other hard things.

Crypto is a LOT harder than some other things.

3d graphics programmers don't have to worry about side channel attacks through timing disclosures through random numbers returned over an HTTP GET.

Physics simulations don't have to worry about tens to hundreds of millions of dollars of losses because Intel changed the L2 cache slightly in some revision of a processor and now it is possible to glean a couple bits of information about the entropy one uses.

Of all the projects I have worked on, maybe the C/C++ compiler had a set of worries close to what an encryption suite has.

You could toss me into almost any field of software engineering and after a few months I'd feel good. Some of them would have a longer ramp up time (order of months). Some of them might require me to go take a few online courses to learn the field (3D, physics sims, etc).

Encryption requires an entire life of devotion. New attacks are coming out all the time. There is so much financial incentive in the field that the competition is insanely fierce.

3D graphic techniques get pushed forward by publishers wanting the latest AAA game title.

Encryption gets pushed forward because they are trying to outrun either large international criminal organizations or entire governments.

2. The Mac Pro, whilst expensive, is good value for money. The dual graphics cards inside it are not cheap at all. As servers with GPUs are fairly niche, this might actually be a cheaper solution.

I'd actually qualify this ever-so-slightly by saying "It's a good value for money if you need the specific features it offers." Which it evidently does to the OP! But many of us would prefer something with, say, one video card, one mainstream-ish desktop processor, and one mechanical hard drive, an way lower costs.
How do you remote provision OS X? I mean, how do you get to the boot menu to choose network boof? With the crashcart?
I'm with you. See a link to a white paper on Docker security. Oh boy! Click on link. See registration form. Bummer.
This is exactly the problem! What you wrote does not sound like extremist talk or paranoia. Certainly not after reading this:

>Bank notes, as an alternate storehouse of value, are a constraint on central banks’ power. “We view this constraint as undesirable,” Citigroup Global Chief Economist Willem Buiter wrote.

He goes on to describe some ways that central banks could stop people from trying to hold on to their cash, thus undercutting the supposedly desirable goal of expanding bank power. They included:

> One, abolish paper money. Two, tax paper money.

One lone guy at NYU's business school made the only (to me) rational observation. It was how the article ended:

> if you’re afraid that central banks are in a war against savers, or that the government will try to control your financial affairs, cash is your best defense. Taking it away “is a prescription for revolution”.
One thing I've learned about lock-free structures: DWCAS[1] is your friend. Using DWCAS, the Michael and Scott Queue algorithm is trivial to implement. Not really sure why the author insists on using plain CAS, especially when implementing a DWCAS-based algorithm.

It's important on medical topics to distinguish message board noodling from actual vetted advice. I'm not a doctor but have spoken to doctors about this specific issue, and, like all of us, have access to the actual medical advice available on the Internet.

Every piece of advice I can find prominently states:

Do not argue with or attempt to invalidate the reasoning of a suicidal person. Listen. Ask questions to gauge intentionality ("do you have a plan? what is your plan?"). Vector them towards professional help. Do not try to fix suicidal people yourself.

Suicidal impulses are a medical emergency.

This may not directly apply to your comment, but it seems very likely to apply to the thread as a whole.
And if you asked them, "Hey guys, raise your hand if you use the web" you'd get men and women raising their hands. "the guys" != "guys" in this case. The word is very - or awfully, depending on your point of view - ambiguous, and can be used in a gender neutral/ambiguous way, like third-person plural pronouns in other languages.
It's the same problem with Android currently which is that when every manufacturer is using the same OS they have to find a way to differentiate. In Android this means custom skins, custom apps, and the like. On Windows this means "free" antivirus, custom apps, and the like. It would be nice if they all just completed on hardware but then it's really a race to the bottom.

I agree, I think. To me the interesting part about putting Mac Pros in a rack is integrating its relatively unusual approach to air flow.

None of these pictures really show how that is accomplished here. In fact many of them seem to be deliberately hiding that specific aspect.
It was something that I struggled with while writing the article -- you don't want to introduce your solution as "well, this sucks in various ways, but keep reading...". It does boil down to viewing things pragmatically though. The Macs present challenges, but by our math, they're worth it relative to the cost of doing something else and the benefits they provide.

And we actually run a lot of them in production, so I've figured out how to do it and not pull my hair out constantly. That's something I'd like to write on as well, but it would be in a different medium. More technical depth, less pretty pictures.

Some guy on Reddit swore by playing a horror game (e.g. Amnesia: The dark descent) when he's feeling down. I tried it with mixed results, but it certainly is a powerful way of feeling something strong and different. Similarly for movies, there are some powerful ones too (for example from Studio Ghibli).

But most importantly: Be with others. Family, friends, random guy in a bar, whatever. Even if it doesn't sound appealing (nothing does when you're depressed) just do it, talk to them.

Yeah, but that's a different phrasing. If you say "You guys can find the pizza in the back", do you think it'll be only men who head for the back?
Yes, in Brazil we have phone apps for calling regular taxis, and at least in the big cities, it's great. You end up with all the regulation that regular taxis have, plus the apps normally have a rating system, so drivers end up caring much more about the quality of the ride.

> Meanwhile in the real world everyone, including women, addresses a group of people as 'guys' - even a group that's entirely women.

No, that's simply false. Sure, lots of people do it. Everyone does not.
For a text article, that's just bad design.
no, I'd like the text to get smaller when I zoom out. Why else would I or anyone zoom out!
Museumify can show you how something had been changing by time
"In 569 allegations of excessive or inappropriate use of force (arising from 363 incidents), only seven were sustained—meaning 99 percent of cases were dismissed"

Anyone getting arrested and resisting will complain that it's "excessive force" when the police use any sort of force to arrest them. If you talk to any cop working right now, they will tell you this. This is why 99% don't see the light of day.

"The two Seattle residents are now the closest thing the city has to a civilian police-oversight board"

If this is even close to the truth, it's scary. They see numbers and text on a report. Nothing is in context to the situation that happened. This is why there are professional police review boards dedicated to investigating these matters...and we don't have armchair/twitter warriors making important decisions like this.

"Then, in February 2011, Rachner met Mocek at an SPD town hall meeting. Mocek had had his own run-in with police. In 2009, security agents at Albuquerque Airport threw him in a jail cell for lacking identification and causing a disturbance. Mocek challenged the misdemeanor charges against him and, like Rachner, won. Their run-ins and legal battles with security agencies galvanized them, they said, to hold police accountable for mistakes and abuses."

So how is upholding the law, "abuse"????

"the largest public union in the state"

This entire article is about railing against the police, yet the unions are never mentioned as part of the problem. Very interesting indeed.
Great to hear they go straight to your inbox. Usually I have the feeling the stuff that is submitted through the 'Feedback' buttons is never read.
This is great advice. While suicide is often associated with depression, because people with major depression are often suicidal, the predominant attitude at the time is often one of unbearably intense anger or anxiety. Getting judgmental or combative is going to increase that.

Also, many suicides involve alcohol (which, in some, produces a volatile state that mixes despondency and extreme anger) and drunk people don't exactly listen to reason.

I think that it can be worthwhile to remind the person that he has friends who'll miss him, dogs to feed, etc. I don't think that laying in with guilt is the way to go. You want to give them images of the people they care about being happy, not images of them being wrecked by their own possible death.
Part of the problem, at least in America is one that people don't want to talk about. The industry has globalized greatly over the last couple decades, and many companies hire in areas that have no labor standards. Companies are operating under US labor standards but are hiring people in greater numbers in China and India, some to work in the US. In those places discrimination by age is commonplace. Additionally, there are a large number of foreign managers working in the US who don't understand why they can't just openly discriminate by whatever standard they want. and it makes sense they are confused if you're allowed to discriminate in some cases but not others at the same company. No one regulates US based corporations hiring people in overseas markets for US jobs. The problem is so bad that many resumes that US managers in US companies have sitting on their desk contain things like age, birthplace, country of origin, family members, and even blood type. It blatantly violates US law.
Using an account that I share with other people in the same team is not the same as 'marketing'. I am sorry if this somehow offends, but think of the handle as just one poster.

I would normally not comment to say "seriously, :/", but this time I feel it is warranted so that people can see how much of an inconvenience this is. As a security sensitive person, I don't much feel like putting a load of information into a form and agree to some random terms I'm not going to read. Yuck.
I'm only 35, but it's obvious there's a lot of work to do to "master" a particular language, or at least paradigm. At the point where you feel you've mastered something, or you've reached the point of diminishing returns? Move to a slightly different paradigm, re-apply your accrued knowledge, learn new things, and grow more.

Yes, the field can be insular, yes, there's benefit from cross-pollination from other disciplines, but the field is vast, and it's reach is still expanding. There are plenty of people immigrating and emigrating from CS that are sharing ideas, you don't have to be one if you don't want to be. If you're happy with what you do, and you can make a living doing it, enjoy it. It's privilege, not a curse.

Excluding people from a conversation based on their education/skill makes sense in some contexts. I only want trained engineers to design and evaluate a bridge I'm going to be driving on, for instance.

In others contexts, we avoid it. Trials are operated by trained lawyers but the final decisions are often rendered by juries of everyday citizens, who might have little or no legal experience.

And of course, anyone can run for office, vote in an election, or lobby their elected officials, regardless of education or training.

Where does economics fall on this spectrum? That's a pretty tough question, actually. It's a highly technical field, but the systems it measures and predicts are broadly inclusive of everyone. Is it engineering or policy? Somewhere in between.

So while I appreciate how annoying it must be to trained economists to hear lay folk expound on auditing the Fed or whatever, I think the culture of the U.S. is that citizens get a say in the policy that affects them. And a lot of conversation about economics are actually about economic policy decisions.
It's certainly plausible. I can tell a plausible story from the other side though - the primary feature of being a start up is learning, and if it's an echo chamber you're going to be learning the wrong things and relying on things other than facts to dictate your business strategy.
from my experience with the dk2 i felt their biggest issues were:

hard plastic frame,
eye tracking,
blood circulation

the hard plastic frame limits the variability of the distance between two pupils. Pupillary distance is ~62mm for women and ~64mm for men(i). With obvious variance even within the sexes. Just hardcoding a distance is a limitation that requires the brain to work harder to massage the inconsistencies causing added strain. ( the images appear to show lenses that are now even unable to be removed, one potential solution i saw was the possibility of buying lens kits for offsetting the lens to your specific pupillary distance )

the lack of eye tracking really disrupts the experience. Look around the place you are in right now, but keep your eyes straight only moving your neck as you move from object to object. The movements are awkward and feel like a retrofuture automaton. Now look around casually and notice how often you utilise the movement of the eyeball. ( unable to tell at this moment if there is any extra hardware in the mask )

as for the blood circulation if i wore the dk2 for more than 20m and took it off to look in the mirror the area around my eyes was white for want of blood and highlighted by the red marks where the mask was pressed against my face. ( the images show the same face pressing frame )

i had many more issues with the dk2, but these three seemed to me to be confirmation proofs that the direction digital stereoscopy is going in is innately flawed

a constructive alternative would be digital stereoscopy that uses eye tracking to measure pupillary distance and the pupils' direction vector in order to create a scene ad hoc, or virtual reality through direct sensory manipulation

When you reincarnate, it's your karma that determines the form you take. If you have bad karma, you can come back as a tapeworm or worse (some Buddhists believe in hell realms-- which are not eternal, but still quite awful-- and some don't).

Buddhism doesn't categorically outlaw suicide but it's against violent or angry suicide and it definitely proscribes suicide as a way out. The bad karma you were trying to escape, plus possibly more, will be waiting for you on the other side. The self-immolating monk, Thích Quảng Đức, might turn out OK if he had compassionate intentions; but in general, suicide is still very bad.

Thanks Deigo! From yours and other siblings comments what I gather is that the idea of a library is not fundamentally flawed, it is just that the state of the art has not matured to that level.
In January, a student from my alma mater flew all the way across the country to jump off the Golden Gate Bridge. I ended up reading a New Yorker article from 2003[1] about Golden Gate jumpers and this anecdote stopped me:

Motto had a patient who committed suicide from the Golden Gate in 1963, but the jump that affected him most occurred in the seventies. “I went to this guy’s apartment afterward with the assistant medical examiner,” he told me. “The guy was in his thirties, lived alone, pretty bare apartment. He’d written a note and left it on his bureau. It said, ‘I’m going to walk to the bridge. If one person smiles at me on the way, I will not jump.’”

He jumped. And ever since I read that, I've made it a personal mission to smile at everyone I pass on the sidewalk every day. Not only does suicide have unknowable impacts on all of the people around you, but even your most insignificant actions could have an enormous impact on the people around you. Be good to others -- you never know how much it might mean to them.

Grooveshark is back already. Or is it?
(I'm the datacenter manager at imgix, and I wrote this article)

I had originally intended there to be a totally disassembled chassis with an airflow overlay on top, but it turned into a lot of work. All of the chassis were already assembled by the time we took the pictures.

The high level view is that air is drawn in to the vent on the front right, which has a separate channel that all 4 Pros sit in. They are sealed in place, so the air has to pass into each Pro's air intake to go anywhere. The other side of the chassis is open to the back of the rack and holds each Pro's exhaust vent.

I'll go through the photos we took and see if there's something that would help to illustrate this better.
Reminds me of Pecunix, Cgold, Egold, Ebullion and E-dinar problems even though this would be decentralized as no central accounting system taking IDs/making user accounts there's still a pile of gold the US gov can seize if they want claiming there must be IDs for transactions. Bitcoin there isn't a central repository of btc keys printed in a bank they can go after making arbitrary seizures more difficult plus no existing laws like there is for gold ownership transfer. I like this idea but predict either a fractional reserve scam where independent auditing isn't done or that tempting pile of gold gets stolen by a government.
My dad just retired from a programming job at 66 years old, and now he's back down to one job, doing programming at his own business for clients like big manufacturing companies. One of his complaints before his retirement is that some of the younger people, including some in their 50s, weren't willing to try new things or follow state of the art practices.
This is like using a sledgehammer to put up pictures. You simply do not need the kind of parallel compute grunt something like watson can provide to do correlation analysis as they describe. You could cobble this together in {dirty secret scripting language of choice} and run it on your laptop.

This is a PR piece - not the article, the activity - to bring forth the idea of computers making decisions about healthcare, based on metrics - not humans, based on metrics and compassion.

The cynic in me sees this as setting a disquieting precedent in the direction of healthcare being distributed according not only to patients prospects and treatment needs, but other factors which a financially liable party, say an insurer, would be interested in - such as the earning potential of the patient.

I'm pretty sure there was a Star Trek episode about this.
