You're right, mathematically speaking the two systems are the same. As a matter of fact, the calculations that describe the attitude of a spacecraft flying not far from the Earth are usually expressed in a geocentrical reference frame. It's much simpler, yet produces the same result you would get using the heliocentric frame.

The real disadvantage of the geocentric system is that it is a barren model: it does not allow science to advance. It is able to explain the motion of planets with exceptional precision, but it does so by using a mathematical construction (the epicycles) that does not lead to a deeper understanding of the inner laws of nature. On the other side, the heliocentric model (when corrected with Kepler's idea of using ellipses instead of Copernicus' circles and epicycles) was a big step towards the bigger understanding of gravitation that was produced by Newton's law of gravitation.
Lesson: RethinkDB should have been at the forefront of offering their DB as a service.

Lots of OSS-oriented companies do this and it works at least well enough to keep the lights on while you can work to get to higher tiers of the enterprise.

Thanks for clarifying. In any case, it seems that Aristotle was mostly forgotten in the North and West parts of Europe, whereas Aristotle was known and discussed in the Middle-East and Mediterranean parts.

At your last paragraph, when you say "It'd been dealt with before" who/what are you referring to?
The 2012 article said they were using beryllium ions, Wikipedia says in 2013 they were planning on using calcium ions, and now the 2016 article says they used ytterbium ions. Without more content to go on, we can only guess about these changes.

In any event, they sure seem to have made a lot of progress in just a few years. I look forward to reading more about this, as well as listening to Neil deGrasse Tyson describe it in his infectiously enthusiastic way.
I spent several years in Houston, and the drivers there are polite to a fault (four way stops are hilarious in Houston). But, if you aren't driving at least 10 MPH, 20+ on highways and toll roads, over the speed limit, you're gonna have a bad time. Houston traffic is the most insistently/dangerously fast traffic I've experienced.

There have also been more shootings on the road in Houston than anywhere else I've lived. So, yeah, that seems scary, but it's not something I worried about when I lived there. In the instances where someone got shot that I know of, the person was kinda asking for it (they initiated violence and the person they were beating on happened to have a gun under the seat or in the glove box).
Facebook is not the Internet though, it doesn't offer any benefits except eating away your free time.

Do you know in this age anyone in USA who doesn't have access to the Internet and also would want it? I never met anyone, like that. I met people who don't have Internet (usually older people), but they are also not interested to have it.

Even if there are such people in US, they can get Internet access in library (together with free books and free newspapers), because surely they also won't be able to afford a computer.
What about websites that don't allow special characters in their passwords?
I have to agree here a bit. However, there was nothing stoping Rethink from building their own service and promoting it as the "official" RethinkDB service. They have the unique opportunity of making it better than any other service by:

-Updating the service the day new versions go GA

-Faster turn around on breaking changes

-Ability to provide authentic expert support

-Ability to provide additional functionality power users would pay for and 3rd parties like compose would not implement

They wouldn't capture the entire market but they could be the leader in it.

The open source business model is hard enough. It becomes very difficult when every other Cloud simply wants to offer your product and you capture none of that. And then the project dies and no one wins.

Open source companies need to be the leaders of their tools, provide the best services around them and differentiate their offering from the open source code base. If you can't do that you won't have a company. Asking for donations is not a business model.

RethinkDB was a good database with a bad business.
I'm not sure how much this has to do with quantity of x as opposed to quality of x.

I've worked in small teams where I was the only Asian person among a team of white men, and I neither noticed any hints of racism nor sexism.

I've also worked in teams where it's been highly diverse in ethnicity though not gender, and again, never noticed any hints of sexism.

Though I have certainly worked in a company with a number of women, including a female co-founder/CEO who was absolutely sexist... against women. I'm not suggesting women are bad CEO's or that diversity is bad, I'm saying that from my experience, it hasn't been about the diversity of the team so much as the type of people in the composition.

Also from my POV, I'm not sure how having a random % of women makes more or less sense than a random % of black people or Latino's. Like if a company is predominantly composed of white men, does adding a white female make it more diverse than adding a black man?
Could this really be used for self-correcting quantum memory, as the article suggests?

> The security and Keychain Access tools have no visibility into it, it's 100% handled by the secd service.

That's not quite true: Keychain Access can write to Local Items keychain, but not everything in Local Items are visible to Keychain Access. Apple changed ssh to store private key passphrases differently than before, in a way that's invisible to Keychain Access. However, you can freely move / copy entries from, say your login keychain, to Local Items with Keychain Access, and vice versa, and they would remain visible.

Fortunately, the Local Items keychain, stored in ~/Library/Keychains/<UUID>/keychain-2.db is just a sqlite3 database, with (presumably) encrypted fields. If you run "ssh -vvv" you can even see the query.

> Edit3: Can confirm that "ssh-add -K -d" does in fact delete the passphrase from the keychain, even though it may throw an agent error.

Huh, I thought I'd tried that before resorting more drastic measures. Or maybe "-d" works but not "-D", hmm or maybe I'd neglected to also pass "-K".
It's wrong.

The concept of infinite substitutability was presented as a "principle" in a 1976 paper, itself trying to argue out of the all too obvious implications of Limits to Growth (1972).

"The Age of Substitutability", H. E. Goeller and Alvin M. Weinberg, The American Economic Rrview, Vol. 68, No. 6 (Dec., 1978), pp 1-11

Somehow this hypothesis has been raised to the level of a scientific law of economics, trumping thermodynamics, physics, chemistry, and 216 years of actual experience of the Industrial Revolution and subsequent industrial periods, as well as economics' own law of diminishing returns.

There's nothing here but wishful thinking.

A news service, such as a newsfeed, has a duty to be impartial by virtue of naming itself news unless there is a real contract with the user stating alternative duties.
And yet, in spite of their extensive training, computers are better at diagnosing.
Surely those are services in a very classical sense: Processes that provide a service that other apps need, and which need to go up, down or be reconfigured dynamically as a response to other changes in the system (such as networking). So far the way to do that has been pretty ad-hoc, with no formal definition of who has the responsibility for controlling the lifecycle of each component. What systemd brings to the table is a way to formalize those relationships and centralize a lot of common logic related to dependency handling and process control.
Floating point numbers handle integer values in the range -2^53..2^53 just fine.
Wish RethinkDB could have created a product similar to MongoDB's Atlas[1] which perhaps could have been the revenue stream they needed.

Sales, the missing piece
Hi,

Bunch of my friends and I created a video hosting platform called RealEnc.com. I gain a lot of experience along the way. Now we finally have a product that I think is sellable. It offers a great platform for companies that's looking to incorporate a white-label video host onto their site. RealEnc offers features like:

1. Dynamic Adaptive Streaming to minimize stream buffering
2. Content Protection
3. Support for Mobile Devices
4. Free Technical Support
5. Unbranded Video Player

Now to the hard part. I have been reading up on ways to sell products through email. Specially B2B stuff. I may have sent well over 30 emails so far with each email catered to its reader. Unfortunately, non of them replied back. Heartbroken but optimistic.

Our team compose of all tech guys and non of them have the slightest experience in marketing or sales. But we are motivated enough to read tones of articles on sales and contact people though email. I want to ask, from those who have experience in entrepreneurship, two favors. One, please comment on one of the email I sent out to a company. Two, please advice us more ways improve our sales.

1. Email: (I used dummy names)

Hi David,

I am Harry from RealEnc.com. RealEnc is a video hosting platform. Besides being an awesome video host, we also provide an exceptional support that covers all aspects of video hosting for FREE. I just want to ask if you would be interested in looking into a better video hosting alternative for Automotive News website.

You will get out full-fledged product FREE for two months. Also, you do not need to worry about technical aspect of the integration, we will make sure of a smooth integration.

2. Below are few question that might help us to improve our sales tactics

Any literature that you think would help us to improve?
How do we find someone good at sales to work with us?

We appreciate you taking time to read this and comment on it.

Thank you
I wonder how their model scales since after all this time they haven't even expanded into Silicon Valley. I assume it only works with the density of a small to medium sized city like San Francisco.
That's like saying "I wish we could charge more for cell phones. I know! We'll decrease the supply and make a ton of money!"

It's a cutthroat market and someone will replace you.
>> a public-PageRank Google doesn't even come close."

> How? It let them dominate search, control much ad revenue, put players with most money on top results, create a major contender in browsing, and later dominate mobile market.

The context of my original comment was that a public Pagerank algorithm isn't an artificially scarce environment. I don't understand your "how" question, and I don't see what the rest of this paragraph has to do with artificial scarcity.

Duckduckgo doesn't have a public spec for their algorithm either, because again, it would render their results useless in a short amount of time. That example should hopefully illustrate how keeping one's ranking algorithm private has pretty much nothing to do with artificial scarcity or abuse of monopoly.
I don't understand your comment.

I have never met a "disinterested academic". To the contrary, most academics are quite interested and many are enthusiastic about their area of study.

Many are also involved in outreach, to get others interested in their research topic. This includes researchers who write and sell books meant for the general public, and, yes, to affect policy.
This is the fate that many OSS business models are gravitating to - developers have no expectation to pay for OSS libraries which drives the price towards free which can only be made back from large volume to sponsor indirect commercial business models. However since there's an expectation to pay for hosting which requires a direct payment connection via a credit card they're easily able to extract sustainable income without needing to pay for developing the OSS software they're hosting.

So most of the profits from OSS will be around hosting which due to economies of scale and brand confidence will flow to large cloud vendors controlled by a handful of tech conglomerates.

The commercial value derived from OSS Software will shift away from authors to big Tech Co's which is also how they're able to sponsor development of a lot of paid OSS libraries around their hosting Services themselves.

The end result is the same, if there is another option available: run

Jumping for the Cure
Honestly, if I get the sense a candidate is chasing the perfect code base, he or she probably would not get an offer. People like that leave unexpectedly once their itch is scratched (or not scratched).

Assuming that the candidate was extended an offer and asked to look at the codebase, I would require an NDA. I work in a niche market so you can't get the secret sauce in a sit down, but there are methods that can give you an advantage. For example, I worked at a place that did something they weren't supposed to be doing to gain a competitive advantage. To this day, 8 years later, despite working at several of their competitors, I still haven't seen anyone else do this thing. I haven't revealed this to anyone and I won't. We aren't doing anything like that, but we do have methods that I haven't seen till now.
The brilliance of that comment is that around here I wouldnt be surprised if it wasn't!
Well, there are some important differences between berry-bearing trees and the larger conifers, as well as all the various different microbiomes we have around the sierra. There's chaparral, scrub, high desert, foothill, subalpine and alpine environments, and they all have different needs and react differently to environmental changes. The high desert stuff, for instance, is really good at coming back from extended dry hot periods. Chaparral, scrub, and foothill aren't likely to change drastically, I don't think (in my totally uneducated opinion).

I'm more worried about the subalpine forest, the kind of stuff you see in the western Sierra from about 3,000 to 8,000 foot elevation. That's where we're seeing the worst of the tree die-off and wildfire disasters, and it's an ecology that takes much longer to return to what we think of as "healthy". The watersheds in these areas is also a major, very important part of the state's water supply, so impacts on these ecosystems have the potential to affect communities all over the state.

Best wishes to you. Good to hear from you again.
Yes. IIRC, the pope allowed him to write a book on his views but to include both sides of the debate. Galileo did so, but put the traditional view into the mouth of a character named "Fool"...
And I am sure if one was to read through everything you said in your life 1000 years from now, you could just as easily be painted an idiot. People say stupid shit. Aristotle was a person, therefore, Aristotle said stupid shit.
Ring plus and Freedompop and T-Mobile already offer basic free internet for various amounts of data. I don't see a need for this.
This is likely also a bigger problem for women, who tend to be less savvy and less aggressive about negotiating for salary to begin with.
The FIDE statutes and International Olympic Committee code of ethics are very clear on not allowing discrimination on sexual and religious matters. FIDE is an International Organization, If they do not respect FIDE's code, they should not apply for organizing FIDE's competitions.
I don't see what this has to do with my comment. I didn't say all men are sexist or all teams are sexist, just stated that there is safety in numbers.

You're lucky nobody said something racist about Asians when you were the only Asian. Otherwise, you would have been in the same situation. But that's it: luck. It could happen to anyone and then the workplace could turn hostile.
We need to be absolutely strict on net neutrality and zero rating or we will end up with something a lot worse than Facebooks "free" internet.

It is hard to argue against free Netflix etc but the end goal of these activities is clearly to centralise the internet (targeting poorer / disadvantaged people first), and turn the internet into a modern television-like propaganda machine.
And that moment when you point at it, but that f-ing pop up doesn't actually pop up...

I have to assume they'll have a "Migrating To Compose MongoDB" article in a few months...

I'm not sure if they do but how much does Compose actually contribute to the project? Will they contribute in the future?

Are they simply a parasite or will they invest in their business by improving the software they sell? If they won't then I would never use them for anything as they are providing a service for a product they have no control over and no desire to invest in and improve and I'm not interested in tying my business to that.
It seems to be unprecedented, at least on the time scale of "middle-aged human". On geological time scales, you'd have to ask someone much older. :-)

edit: for a less flippant reply, a lot of folks don't realize that vast swathes of what we now consider dense forest were all logged to the ground from about 1800 to about 1930. That's what makes places like Sequoia National Park and Big Basin State Park and parts of Humboldt and Mendocino counties so unique -- they're the remnants of old growth forest, and it's a very different kind of forest.

So perhaps it's not right to talk about this in terms of the "health of the forest". Much of the current forest could die and be replaced by entirely new forest over the next hundred years.

A better question is, what kind of environment do we want to be able to enjoy during our lifetime? That environment is currently struggling.

I don't much care for hiking in burn scars and dealing with muddy places in the Winter, so I'm pretty interested in what's happening to the forests right now.
thanks, i did mean specimen page, mea culpa. also thx for the link!
> That's why someone like Google just seems like a good fit for Twitter

Someone else in a different thread mentioned that Twitter isn't exactly in great books with various world governments who are friendly, or at least neutral with Google currently. Is Twitter's revenue worth the additional risk of regulatory scrutiny/antagonism to Google?
If you're happy to allow fellow humans to continue along a poor path, sure. I believe in establishing feedback loops and giving people opportunities to grow.

Tongue-in-cheek aside, of course passive-aggressive isn't the ideal path to improving interview processes. :P
I vaguely remember the C64 had something like this. You could move the cursor up to an old line, modify the line, then press RETURN to run it. Mind you I was like 8 years old.
Expanding comfort zones or shifting your baseline for hedonism
I think the ads on stories are certainly intrusive. It's one thing to have sponsored filters (I personally try to avoid sending them), but I find it very jarring when an (often significantly louder and brighter) advertisement interrupts a friend's carefully curated story.

I'm probably being too harsh on Snapchat. They're under a lot of pressure to monetize their platform and, by most measures, they've done a great job integrating that need with a minimum of user disruption. I don't even remember when sponsored filters appeared for the first time, which is a testament to how seamless that introduction was.

I appreciate that they still allow users to tap through advertisements, but part of me wonders if that's a stop-gap towards a future marketing move ("pay 25% more, and users can't stop your ads!"). I hope I'm just being pessimistic, but that's why a slightly more misanthropic me would do in their position.

They're definitely in a very strong position currently, and I too am impressed with the company (I think that their Spectacles move is brave and forward-thinking in all the right ways). If I was an investor, I'd be feeling pretty excited right about now.
> I don't want free internet.

To be clear, Facebook is not offering free internet. It is offering "Free Basics", which includes specific services made to run on the platform. Most sites on the internet would be inaccessible through Free Basics.
tldr;

Premise 1: Humans adapt to our environments as they change and we become desensitized. Our experiences shift the baseline against which we measure experiences in future. [1]

Premise 2: The further away an experience is from our baseline, the more intense the experience (but with [exponential?] decay). [2]

Conclusion: If we gradually expose ourselves to less comfortable experiences, we can shift our baseline to better appreciate the more common pleasures in life.

[1] This applies to both someone getting used to their new car, as well as not showering (as an example, not recommended).
[2] So, for someone who's baseline is barely not freezing to death, having a shelter against the wind and snow would be quite the pleasure. Meanwhile, Europeans who are used to well insulated homes complain about damp uninsulated houses in New Zealand.
This is true. Especially South American slash and burn of the rainforest for cattle grazing is a huge contribution. We're burning through our largest carbon sinks and also the most diverse ecosystem to raise meat. Switching to alternatives like lab-grown meat and vegetables would do more than anything to stop both climate change and species extinction. It's insane that we're dancing on the edge of the extermination of life on Earth because of flavor. I do think that it'a important to look at the other side though to understand why we're following these kinds of practices. There'a a lot of culture tied up with meat, and we won't be able to get past it unless we address the reasons for doing it on all levels.
First National Bank (FNB) in South Africa has adopted every one of these absurd rules, and more:

Passwords must contain a mixture of upper and lower case letters as well as one letter and one special character

Length between 7 and 33 characters

Not the same as the previous 12 passwords

The same character cannot be used consecutively

Avoid sequential letters and numbers (123 or abc). I think this used to be enforced, not sure if it still is.

May not be the same as the name, userid or clientid. As I recall this is enforced by very aggressively with innocent passwords being rejected because they happen to have some matching substring.

https://www.fnb.co.za/demos/reset-username-and-password-PC.h... (rules are on the 5th screen in their demo)

I've been using the same password for 3 years because changing passwords is so brutal. Complaining is futile because of the bullshit cargo culting around security.
