The benchmarks show a fair number of -1s (not supported). What isn't supported exactly? I don't see these limitations listed in the limitations section.

I have ZERO patience for this type of behavior in a product aimed at professionals. I use Win 7 professional to do my work. I have a specific set of software that I use, and no intention of changing anything about a setup that is tuned and works well for me. As far as I'm concerned, a product that I paid for which suddenly tries to hold me hostage like this has turned actively hostile.

It's an open source tool. If you'd like support to be added for your camera, take a look at this page:

The lens correction comes from the lensfun project, which is also open source. They even run a lens calibration service if you submit the necessary images:

http://lensfun.sourceforge.net/

A lot of distributions have ancient versions of lensfun for some reason, so upgrading can make a big difference. They're currently working on splitting the lens definition file into a separate package from the software so that it can be updated more frequently.

If you have any questions for the developers you can always jump on to #darktable on freenode IRC. darktable 2.0 has just entered feature freeze.
Arguably you wouldn't object to taking out nearly any random person on the other side of the world who you didn't know personally. That's not the point.

It's a lot easier to just randomly assassinate people across the world than to come up with a sound policy that protects our interest while also obeying our values as a people. Historically, western culture has not condoned execution without trial.

The notion of just lumping anyone within an age range into the category of combatants is so antithetical to what the US ought to stand for, that it's really quite shameful. It's only a small degree away from the ethos of so-called terrorists, who just try to kill anyone they can.

What it boils down to is that the US is practicing terrorism abroad. I'm sure there would be circumstances where I'd approve of drastic measures, but at this point I'm very far from convinced that such tactics are remotely necessary or appropriate.

Everything I've heard about this company is just weird. A biotech company started by a 19 year old Stanford dropout. She didn't even finish her second year in college, so she never made it past the intro courses.

I can understand a 19 year old starting a software company, but this is more like a 19 year old starting a semiconductor fab. Someone just gave a her millions of dollars and a decade to run what was basically an r&d lab with almost no relevant experience?

Then the company's board is composed of 2 former Secretaries of State, a former Secretary of Defense, 2 former Senators, a retired admiral, and a retired general. They only have one currently licensed physician (who also happens to be one of the former Senators), and no current CEOs [1].

I think an actual war (as opposed to the stuff US is doing in Iraq and Afganistan), in which you and your family could get hurt, does wonders for productivity because it forces people to keep things real. There's less time and will for graft and bullshitting, you need to work because your survival depends on it.

I like to think of Avro in two (related) parts:

+ A very compact binary serialization, which lets you efficiently store or transfer data over the wire. (Avro actually also defines a way to encode your data as JSON in cases when you need a human-readable representation.)

+ A way to define "data types". For example this schema [1] defines what we expect a "Human" entry to look like, and we can now do things like check whether we are missing any information, make sure all fields are valid, sort, efficiently copy objects, etc.

This is glossing over many things (files, RPC, ...) but I hope this helps a bit! You can find a lot more information in the official Avro documentation [2] if you're curious.

Question: what, if any, phone do you use these days?
Hi!

Dropbox two account works great. It's specifically designed to keep your personal Dropbox completely separate (and unscrewup-able) from your company assets. We built it because people had been intermingling personal Dropboxes with company assets and it created messes for them when they left the company, etc.

Anecdotally, I've had my personal Dropbox account since 2007 (was one of the first 1000 beta users), and my family manages tons of stuff in it. I started using two account in 2013 when joined Dropbox (the company), before we released it publicly. Your existing Dropbox gets moved to "Dropbox (Personal)" and a second folder gets created called "Dropbox (Your Company)". Nothing changes about the behavior of "Dropbox (Personal)".

No problems whatsoever with the separation of personal and company--and that reflects the vast majority of our users' experiences as well onboarding a team.

As another user in this thread mentioned, Dropbox doesn't support 3+ accounts, so if you work for multiple companies (who all use Dropbox), that might be a problem.

Just a guess, I think the other problem report in this thread was someone who wasn't expecting Dropbox "for teams" to create a completely new type of account for everyone at his/her company. They probably use basic or pro accounts in an ad-hoc way at their company and were unfamiliar with the teams product and the fact it is distinct.
I've found the admin to be hostile to discussion of biological determinism and have given up on discourse on this site. I'm surprised to find, given the general tenor of the commentary on this thread, that there has been a seeming absence of intervention. Perhaps on sex he is more tolerant of such views than on race.
Most of the critic (and user) reviews are what I think of as "easy mode" ones. They don't really teach you anything about the film, just say whether they liked it or not, using the most colorful language they can possibly muster. The FF quote seems like a typical example.

Alternatively there are some that really dig deep into the meaning and execution of the film and analyze it in ways I would never think of, not having a PhD in literature or having been to film school or anything. An example I like a bit is Film Crit Hulk[1], which range from simply explaining why the film's execution didn't match its themes (Jurassic World) to borderline philosophical treatises on the meaning of film (Birdman). (Imo, obviously.)

For getting a quick rating to see what soared/bombed, stuff like RT and IMDB serves its purpose, but I wish published reviews would do more of the deep dives into film analysis, rather than just letting some random journalist vent their opinion for pageviews.

Your first link is talking about a more specific group of people than I was referring to. It references about 7% of the population, people working at least half of the year who are below the poverty line. The 2013 poverty line was $11,490 for individuals, $23,550 for a family of four. I'd consider twice that to still be poor by any reasonable definition. In my area (around Atlantic City, New Jersey) you'd be lucky to find a two bedroom apartment for $1000/mo. So if a family of four crams into a two bedroom apartment, or an individual splits one with a roommate, that's half the 'poverty level' in rent. Without covering utilities, transportation, food, etc.

As to your second point, I'm sorry, but I simply don't have the time to do the proper research on that one. You may be correct. I was primarily basing on anecdotal evidence from what I've seen and experienced in my local area. The statistics may also not be as clear as one would think. As I said, in my area, someone at twice the poverty level would still struggle to get by, and in many cities, I expect it is significantly more. At the same time, in many rural or semi-rural areas, housing costs become a much smaller factor, which leaves more room for things like a vehicle. Looking at the poor based on the amount of income, without looking at circumstances at an almost individual level is a difficult prospect.

I will also say that it is easy to overlook things that go from a non-issue to a time and effort consuming problem when lack of resources is involved. Lack of transportation or a washer were just two examples that came to mind. Also note that if 74% of poor households have a vehicle, that means 26% do not. That is a fairly significant number, in my eyes.
All good questions, all of which are answered in the white paper. An "elected leader" is essentially the same thing as a miner that mines a block in Bitcoin. Miners can mine empty blocks in Bitcoin. This is OK, as others will step in for such defunct miners. Likewise, in Bitcoin-NG, another miner will step up if the elected leader does not mint microblocks.

Keep in mind also that NG would be layered on top of Bitcoin, so everything that works in Bitcoin will work in NG as well.

My team is remote, a couple of us been together 10 years and most of us at least 5 years. My managing style I picked up from my mgrs in the company. Pretty hands off. Stars are stars and don't need me meddling - so the general style - let them do their thing.

As far as the average or underperforming employee, I view my job not as trying to "improve people". I need to empower people. As a leader you have some influence on your team, but I think that's a bit overblown. A person's performance is really a result of their mindset.

Their IQ as well. That's important, but some people are just motivated for excellence, others not. I think the key is - understanding where you have opportunities to influence this in your team members' and when not.

One thing I did notice - moving to a mgmt position. It is very temptimg the idea to just get rid of them. It's tough but easier then getting someone truly hopeless to make the necessary effort to improve.

Theranos is secretive and doesn't behave like other diagnostic testing companies, and these deviations generate controversy.

Theranos have been very, very squirrelly on details about their testing platform, claiming that they need to keep them as trade secrets in order to maintain competitiveness. Ordinarily, the tests would be independently evaluated in the peer-reviewed literature, and through the literature is how scientists and physicians would assess the value of what Theranos is offering; without peer-reviewed literature, there is little to go on. Maybe it works, maybe it doesn't, only peer-reviewed literature counts so we don't know.

Theranos has an unusual board of directors for a diagnostic testing company, with surprisingly little medical experience overall. Holmes herself is a college dropout—it's very hard to compete in a highly specialized and technical field without the proper knowledge base and experience, and traditionally that would be with an M.D.+fellowship or Ph.D.+postdoc. In interviews, when things get the least bit technical, Holmes sounds like she doesn't know what she's talking about. Theranos' patents, of which Holmes is a named inventor, are (IMHO) vaguely written. Could Holmes be a diagnostics savant? It's possible, but I don't see credible evidence to suggest this is the case.

The popular media has hyped up the company technology a lot, but in reality microfluidics is not new to the diagnostics arena, and it remains unclear as to what exactly Theranos offers as an advancement on what others are doing. There are also many technical issues to be considered with fingersticks vs. venipuncture samples, and Theranos has never explained how they have overcome those issues other than unsubstantiated assurances that their tests match standard lab tests.

There is also a fundamental problem with the entire hypothesis underlying Theranos: which I very crudely summarize as more tests = better health. That hypothesis is sophomoric and does not hold under the current thinking of evidence-based medicine. One can over test, and it has real, proven consequences towards the health of the patient in terms of invasiveness, costs, and potential risks due to unneeded procedures.

Does Theranos have something unique? It's not impossible. My null hypothesis is that they do not, and until I see something in the peer-reviewed literature suggesting otherwise, I am thinking it's smoke and mirrors.

Edit: All that text and I didn't directly answer your question! Consider my bloviation proof of my credentials as an academic. The earlier WSJ article raised questions about irregularities in regulatory-mandated proficiency testing, a serious allegation. My interpretation of this new, linked article is that there might be something to the allegation.
Another way to "save on weight" is to use the lowest-cost launch from Earth, and rendezvous in orbit. We're going to know what the risk and cost of reusable Falcon 9 and Falcon Heavy is long before we'd start building this lunar base. A 75% reduction in SpaceX's already low launch rates would be a big savings.

We even have experience launching fuel to ISS on the Russian and European unmanned supply ships.
Oh hell yes! I didn't realize we had any private space industry in Europe (besides the fine folks at Copenhagen Suborbitals, who are a non-profit). Could you provide more details? Thanks!
Miner consolidation is a long-standing problem with Bitcoin itself.

When Ittay and I discovered selfish mining [1], we were quite worried about the size of mining pools at the time. Even though we also came up for a fix against selfish mining, the fix only prohibits selfish mining for pools <25%, and we also found that there can never be a fix to prohibit selfish mining for pools >=33%.

Things looked grim for a while, and we played a role in pushing back against GHash when they exceeded 51% around April of '14. The only tool that the community had at the time to break up large miners was just social pressure.

In part as a reaction to GHash crossing of the 51% line, we [2] and Andrew Miller et al [3] came up with techniques based on non-outsourceable puzzles. This is a cool technique that would make it difficult for miners to run large open pools. It does require a potentially disruptive change to Bitcoin, so it's good to have in one's back pocket if the mining situation gets out of hand, but it's not something you want to deploy.

Luckily, Ittay's subsequent work on the Miner's Dilemma [4] discovered an incredibly interesting result: it pays for miners to attack other miners who are running large open pools. This puts natural pressure on miners to not open themselves up to the public and accept people into their pools willy nilly. This in turn is, I think, fantastic news, as it means that the problem may take care of itself, at least when it comes to open pools.

Overall, the distribution of mining power is a point of concern for everyone in the Bitcoin space. The situation looked bleak at first, as it looked like there were few mechanisms to keep open pools from growing ever larger. But now we have a strong technical solution and a natural process that is well-characterized. Large solo miners still remain an ongoing concern.

Hope this is useful.

They do, after you define objective criteria for clustering the objects in a set. For biological race, the main criterium would reveal a genotype-level clustering that matches the phenotype differences - and we see this in dogs, but not in humans.
I never trust any online reviews, especially aggregate reviews, because I have never found any to hew remotely closely to my taste (the best example is on RT, the worst movie I've seen in the last two decades is rated 95% fresh).

The only approach I've found that works is to pick a professional reviewer that is marginally close to my taste, read a lot of their reviews, so I know where I tend to agree and where I disagree with the reviewer, then build a mental translation, so when I would see Roger Ebert trash a David Lynch movie, I could discount it because I know Ebert's antipathy to Lynch in not something I share.

The problem with Rotten Tomatoes scores is that people want to treat them as a measure of how good a film is...it's a natural tendency considering it's a score on a continuum. But what Rotten Tomatoes scores actually represent are a measure of what percentage of people a film will please enough to give a positive review. Just like the The World's Funniest Joke [1] (which most people find "meh, kinda funny"), a movie can rate very highly on Rotten Tomatoes without rating very highly on anyone's list of movies.

But most of the films we'll enjoy are more polarizing. A smaller group of people will really like the film and a sizable group will dislike it. As such, Rotten Tomatoes is a really terrible way to choose a good movie and a really great way to avoid bad ones.

It turns out that if you use arc for something critical, the language itself won't break. The programs written in Arc might contain bugs, but as far as I can tell, the underlying infrastructure is solid.

This is going to sound like bullshit, but a couple years ago I wrote a site in Arc and left it running by mistake. It was set up to push hourly backups to Tarnsap, and the site was doing useful things, but I never ended up needing it.

Turns out the site continued running for 1.4 years by accident. There weren't any scripts to restart the server on a reboot -- it simply ran for that long. Presumably it halted because Amazon rebooted the micro instance or the account ran out of money. When I checked the logs in Tarsnap, I was pretty amazed to find that it had served 37k requests, almost all of which were automated fuzzers. I hadn't launched the site; it just happened to be using an obscure URL. The site had a bit of dynamic functionality, so it wasn't merely a static site. But I hadn't written it cleverly or carefully. Arc is what carried the site for those 16 months, not me.
