The book "Seven Databases in Seven Weeks" may be a good start. It may not answer all of your questions, but it does a good job summarizing various types of databases. Honestly you can read through it in a day or two - I don't think there's much need to install the DB's and do the exercises unless you're looking to explore a certain DB in more detail.

I originally skipped over the first chapter on Postgres but went back and read it and learned a few things (too bad there's no mention of the recently added json and jsonb data types).
Tom Wolfe wrote “The Tinkering’s of Robert Noyce” about the founding and early culture at Fairchild and Intel for Esquire in December of 1983 and updated it for Forbes ASAP fourteen years later as “Robert Noyce and his Congregation.” (Aug-25-1997) see http://www.forbes.com/asap/1997/0825/102.html the updated version makes a much stronger connection between the flat hierarchy of the Dissenting Protestant churches and the egalitarian nature of many Silicon Valley startups.

Another simple explanation:

Imagine that there was one single person who was friends with all 7 billion people on Earth. Assuming nobody else had more than about 250,000 friends, this would cause every other person on the planet to have fewer friends than their friends have, on average. That one person skews the mean.

What happens in reality is of course much, much more subtle.
Sorry, that is from the article (the OP), not the paper that was linked to. The article states that the 10% of people who actually pay attention to the speed limit increase the differential between speeds of cars when the speed limit is too slow.
We've been very happily trucking along with Ansible the past year or so over here at Front Row. Tried Chef for a few weeks, hated every moment of it, switched to Ansible and it all made complete sense.

For us Ansible takes care of configuring the various types of machines we have in AWS, of building, testing and deploying binaries, of configuring and keeping our development environments in sync and more.

It's pretty exciting that the project keeps getting better with every version.
>Is destroying jobs an appropriate driving force for a young company? I think the answer is no.

I think the answer is yes. Making human effort unnecessary is a good measure of value having been added to the world, because that human effort is now free to do something else.

Pity the stagecoach drivers, but don't let it stop you from celebrating the automobiles.
The article mentions two possible paths forward, but I can think of a third. Make the spheres large enough that swallowing is impractical. 1.75 inches seems to be a standard for this. Would giant magnetic spheres not be fun to play with?
sometimes the barrier to entry is simply not knowing anyone you can ask. I'd almost suggest something like 99 designs but, the problem with that site is it significantly devalues the work of artists. I would hope that any tool that surfaces for this niche is more respectful to the craft than that.

Nice design; fast and functional too. Kudos!

So while the fuzzy matching is neat, sometimes it's handy to be able to perform an exact search as well.

Typically this is done using "quotation marks" around the search term(s).
It is easy to promise that for people which don't "argue" by dismissing Wikipedia, BBC etc -- because they have posted a youtube link somewhere where they interpret what someone said as different.

What about something like self-driving vehicles? In particular, Semi Trucks. That's a technology I look forward to, but it will destroy jobs. Self driving trucks don't enhance the ability of the driver, it replaces the driver. Self driving trucks can do 36 hours of driving in 36 hours. A human driver will take 3 days. Your whole truck fleet is idle at night, and you need huge cabs to accommodate basic living needs of humans. Etc.

I honestly hope someone is trying to make this happen, even though it'll completely kill millions of jobs. Hopefully the drivers can find new skills. The economy certainly wouldn't mind an extra 1 million programmers.
The funny stuff was the totally hacked leader board :)

Sorry, but there's truth in patio11's statement that, as a developer, "You’re in the business of unemploying people. If you think that is unfair, go back to school and study something that doesn’t matter." [1]

Doing things that matter, changing people's lives, that SHOULD change what jobs people do.

Really? There are a lot of jobs that could be automated. If you are writing software with the goal of improving current processes, sometimes you can get a better result by looking at WHY the process exists, and if it could be replaced entirely.

An example: Self driving cars will eventually put Taxi Drivers out of jobs. Does that mean a Start-up that wants to be in this industry is evil? I don't think so.
Magnicube is the one that just settled, Neoballs is a subsidiary of Zenmagnets

Klikyballs' website and product packaging seem to be very reminiscent of Buckyballs, but I'n not sure if they're related or just trying to cash in on the similarity.

So their marketing is a tad bit closer to truth than it might appear on the surface ;)
If he takes after Lockheed and the rest of the industry, he'll wrap his tentacles around at least a few states in order for them to shout when he says.
As someone who didn't realize about the risk of those things. And cursory google doesn't seem to have that much info, what exactly is the risk of swallowing them?
I did a (tiny) amount of work / discussion with one of our smallest police forces years ago (I wish I had been able to carry on they had needs that could be met fairly simply but with a big wow factor)

Anyway I would be careful with any analysis of images - this is the vilest stuff humanity does, and you can't hand round a corpus at a hackathon and say "come up with an idea".

What those two points basically mean is I would go find some experts from the police / NGO communities (it seems you are working with NMEC?) If it's still similar to my (ancient) experiences then there will be plenty of low hanging fruit that is not available to most police forces as OSS or as easy-to-use.

This is one area where the freewheelin nature of hackathons might be better tamed.

(I could not quite understand from your page if you had planned something like this (teams will be asked to ...)

Tl;dr - hackathons seem too freewheeling and impermanent for such an important subject - it might be better long term if you worked with police / NGOs to become "product managers" for the teams. And focused on teams with longer term "availability" than a hackathon.

But good luck - my tiny out of date knowledge says there is a lot of really obvious and easy coding that police forces are either missing or paying through the nose for, and you could make some serious headway.

i'm totally curious. i don't get how any of these schemes are supposed to work except in small bursts or at short distance.
1. the amount of power that can be used for transmission must be equal or smaller than that collected.
2. so if the device transmits, the transmission is weaker than the noise.
3. so perhaps power is stored and transmission is done in (short?) bursts?
4. or does it work only at some very short distance thats a (small?) fraction of the range of the powered wifi AP?
Destroying jobs with technology is one of the primary ways we've improved productivity over the past half century. I understand not everyone thinks that's a net positive, but if you're one of those people then you shouldn't try to create productivity software.

At the macro unless your name is Oracle your productivity software will reduce the number of people needed to accomplish a task. Assuming your software works of course. Patio11's main product is to replace secretaries, while improving customer retention.
The solution is pretty simple: people who have kids that eat rare-earth magnets should just have smarter kids.
I agree with you. Thanks for helping.
From my understanding, they're only dangerous if you swallow more than one of them; then they can attract each other through organ walls and cause serious damage.
The velocity boost for launching from nearer the equator is only part of the advantage. Another major factor is that many of the most expensive commercial payloads (such as major geosynchronous comsats) need to end up in equatorial orbits. The latitude of the launch site is also the minimum inclination of the initial orbit the launch vehicle can provide. At the equator you can launch into any orbital inclination. At the North Pole you can only launch into polar orbits. At 45 deg. latitude you can only launch into orbital inclinations of 45 to 90 deg. The higher the initial orbital inclination the more work you'll have to do (the more delta V you'll have to apply) in a plane change burn in order to get into an equatorial orbit.
If multiple small magnets are ingested, they will likely pinch and rot tissue while working through the intestines. Without reading, I don't know if any children (the main culprits of swallowing small items) have died, but I know some have gone to the ER.
Swallowing one is no problem. But if you swallow two of them separately then they can attract each other while traveling through your intestines. The magnetic force is strong enough to perforate your intestines, requiring surgery. Without treatment they can lead to sepsis and death. I'm all for keeping them legal (I have several sets of Buckyballs) but they can be seriously dangerous. That combined with the fact that they look perfectly innocent is the real problem.
this just shed some light on the same question I had for me:

http://en.wikipedia.org/wiki/Neodymium_magnet_toys
Your slippery-slope approach is fatuous. It is a completely nihilistic approach to any sort of legal system that involves regulations and penalties for breaking them.

It is a completely fair point to ask where on the realm of regulated toys buckyball-style magnets fall. Someone doesn't have to be a troll just because they disagree with you.

Also, what is with your last sentence? Are you suggesting that not allowing running with scissors is indicative of creeping authoritarianism? You would have been disappointed with every teacher I had, then.

edit: thanks for the downvotes. A useful reminder to me to never discuss anything with libertarians.
Two magnets can steady each other with a fold of your intestine inbetween. It will cause an ulcer and require surgury. It's actually really bad.
Smalltalk is often smalltalk because we don't want to waste mental bandwidth with the conversation and yet don't want to offend. I agree that probing this state is exactly why we should use brand conversation starters, unless you are clearly in a position where you might want to talk.

That's probably difficult to see for a comedian, since he's never wasting mental bandwidth with conversations -- it's the thing they do!
> What are the practical, non-entertainment benefits of magnet balls? If there aren't any -- if they're a toy, a novelty -- it seems completely fair to hold them to a higher standard.

By the same token, we could argue that movies should be banned because the images can trigger PTSD and epileptic seizures, and movies have no practical, non-entertainment benefits.

It's one thing to say that a product should be re-designed to provide the same utility in a safer manner if that's an option. But it is not the government's place to make wholesale subjective decisions about utility to begin with. That is, it's one thing to require that Ford fix the design flaw in the Pinto that made it conducive to explosions because no one really wants an exploding car. It's another to ban cars altogether because public transit provides a safer alternative to personal automobiles.
If you swallow two (or one and it breaks in half), there's a risk that they'll clamp together inside you, with your intestines in between. Having played with neodymium magnets, having this happen to your finger or ear isn't pleasant, but the real risk is that they'll clamp together and tear a hole through your guts.
I've often wondered how a database such as this can be used in other fields of programming like say, a text-to-speech engine[1] where using subtitles the algorithm can guess the context of the conversation to produce better results.

Hi everyone I'm the author of this post.

The point I'm trying to make is that there is a difference between your mission and the mission's unintended outcome.

As an engineer, I don't believe my mission is to put people out of jobs. In response to some of your points:

Yes, self-driving cars will put people out of jobs. But is that the mission of Google? No, their mission is to make people's lives easier / better.

Yes, electric cars will put gas-pump attendants out of jobs. Is that the mission of Tesla? No, their mission is to make people's lives better through sustainable transport and removing our dependence on fossil fuels.

I think it's important to focus on the value-add portion of what we do, and especially not treat the negative fallout (people losing their jobs) as some kind of marketing angle.
They're both great wedge issues to get draconian legislation rammed through a reactionary Congress. The excuse-du-jour is either terrorism or child porn.
Adding/creating value and the destruction of jobs are not mutually exclusive. Value can be created through innovation that results in job destruction. Furthermore, a product or service that eliminates one job can easily be responsible for creating one or more new jobs.

The author's Salesforce example is particularly naive. While it would probably be inaccurate to claim that Salesforce alone slayed Siebel[1], the reality is that Salesforce did upend the CRM market. In doing so, Salesforce created significant value, but at the expense of established CRM software providers and many of the integrators that relied on the demand for their products.

The best code is the code you don't have to write. I like these short cuts and I played and lost a game against this beauty after reading the code. He did not use any chess-specific libs. Just pure and simple python.

I am proud to not contribute much to LOC counts on most of the teams I worked as I clean up a lot after my colleagues to keep code duplications low and pointless code out. Less code is normally easier to maintain as long as you follow some other coding practices and don't go and inline everything.

As a comparison, Salt checks the users, groups, ssh keys, etc. in under 1 second. Ansible to do the same set of actions was taking nearly 2 minutes. This was just to check, not even to take action.

So, yeah, the majority of time in an initial run is waiting on apt/yum, when nothing is changing the majority of the time is spent on checking things.

When you're making config management a part of your application's deployment process, waiting on checking is painful. This would have added 2 minutes to deployment time. When we doubled the number of users managed it would add 4. That's a really, really long time.
So then your post was a bunch of hand-waving about an ad from a competitor clearly designed solely to grab an individual's attention and improve CTR?

There is truth to it, but that was not the argument put forward in the post.

My post is about using that as a marketing angle for your startup - which I find distasteful. There's so many other, more positive things, you can use as your marketing message.

I think the difference between the magnets and skateboards, bicycles, trampolines, etc. is that you can LOOK at those three and know that they are dangerous. The magnets are sneakier.

Unless you can afford a private school, I don't think San Francisco is a good place for kids. I take my daughter to the Exploratorium, the Palace of Fine Arts, and the San Francisco Zoo, and there's also a nice playground near the skating ring close to the new Target, but other than that I've always avoided the city. It's just not a kids kind a place.
Distasteful? Maybe. Ineffective? Quite probably (considering the decision makers who are buying a Social Media tool are often Social Media Managers). However, if you're going to be as uncomfortable with software eliminating certain job categories and putting people out of work as the OP claims they are, you probably shouldn't be working in technology.

Salesforce (a company specifically mentioned by OP) certainly didn't aim to put salespeople out of business. It did, however, greatly reduce the need for assistants and secretaries that used to be instrumental in keeping salespeople organized, thus eliminating many such positions. Mailchimp (another company mentioned) certainly created some new email marketing positions, but in the process it helped optimize email-use, which is itself a kind of optimization of traditional mail. Thus one could reasonably argue that Mail Chimp helps put people in the paper industry and in the Postal industry out of work.
Well I don't want to die but I also don't want the ticket. In SF between Candlestick Park and Oakland the speed limit is 50 but most traffic goes 65-70.

I have a friend who got his last point going 65 in that area. He pays $7000 a year in car insurance because of his points.

So, I'd rather they raise the speed limit to 65 (so people got 65-70) rather than keep it at 50 which almost everyone but a few (me) ignore.
Wow those are some horrible numbers. Am I just lucky that cabs in Seattle are reliable? I've never had a no-show, and cabs have always been on time here +/- 5 minutes of the requested pick up time.

Then again my sole need for cabs has always been "I need to go to the airport at 4:30am", a need for which I imagine Uber would not be appropriate.

The XOR scheme is perfectly good enough. If it were a real issue affecting customers it would be replaced (but it isn't).

The XOR scheme is extremely cheap (compact) and does not need to operate serially on the data stream (good for performance). The only applications that use the NAND provided randomizer are the cheapest of controllers. In fact, even the SD controller in the linked article used their own XOR scheme. A system designer can always turn off the builtin randomizer, and replace it with whatever method they choose -- they all do for various reasons. At the controller level it can be implemented in, typically, higher performance and more compact logic processes. It does not need to be duplicated for multichannel devices, as it would if it were in the NAND.
I know some people who were in the military who are very smart and technical, so I don't doubt there are some good people in there.

On the other hand, while this is admittedly very anecdotal, one really obvious common thread that I see in the vast majority of great hackers I've met has been a distrust (if not borderline disdain) for authority and seemingly needless process; which I have to imagine (having never served myself) doesn't fly really well in the military.

You're certainly free to interpret it as such.

What we find distasteful is inherently subjective after all. Designing ads is a tricky one (and really, I have never had much of a result from this type of paid advertising so I don't do any) and I recognize the need to maximise CTR where ad budget is concerned.

But in the same way that Godaddy uses buxom female models to promote their products (which works well for them) and some people find that distasteful, I find this distasteful.

It's a personal opinion.
I love the idea of that, just suppose it didn't feel that way in practice. Tad jealous to be honest!
One of the goals of marketing is to attract attention (more specifically, to create demand). Bold statements like these get attention -- the mere fact that you dedicate a whole blog post to it means it worked.
