Slava @ rethink here.

The idea behind the architecture was that performance should be significantly better than rolling your own infrastructure, because the database has a lot of information that userland (from the database perspective) software doesn't.

The performance of inserts might slow down slightly (matter of microseconds in insert latency) if you create many feeds. The database has to look at each insert and figure out if it applies to any of the feeds. This code is written in optimized C++ and is very fast. We're still running benchmarks, but we're shooting for performance levels where you (as a user) might not even be able to measure the difference.

The same applies for inserts that aren't affecting feeds (on a per table basis).

Same goes for throughput -- it might slow down slightly, but we're shooting for making the slowdown barely measurable if at all.

EDIT: in clustered environments, if you're subscribed to 1000 changefeeds on machine A and a write happens on machine B, we do constant work on B to send the changes to A and then A does all the work to figure out which changefeeds need to see it. TL;DR: We don't block out other writes for time proportional to the number of feeds.

I was once labeled an "MRA" for suggesting sexual assault (or worse) and IPV statistics might be more balanced between different genders if the data collection efforts weren't skewed so far toward a single gender.

I used to be a lot more idealistic, but ideologues broke me of that faulty thinking.

Changefeeds are currently bound to a database connection, so they will get terminated if for example the application server goes down or there's a networking issue.

We feel like for many queries (especially the ones you find in web applications) that's not a big deal, since you can efficiently re-run them after reconnecting. In other cases it definitely matters, and we are going to add what you describe in a future release. You can follow the progress (or chime in if you like) at https://github.com/rethinkdb/rethinkdb/issues/3471 .

IIRC, the options for ammunition were, at least on a military scale, severely limited. Using the standard .30-'06 ammo would have been impractically heavy and powerful. Lighter rifle ammo suitable for combat was practically nonexistent. That left .45 ACP as the only viable option, hence it's use - not the suitability for close-in fights.

Possibly interesting subsequent history... In 1934, USA practically banned sale & possession of machine-guns (a $200 tax (equivalent to $6000 today) on a ~$50 product). In 1986, that became an actual ban (for post-'86 products). As such, the market incentive to develop modern & sophisticated automatic weapons pretty much ended with the M16 (the USA having by far the largest civilian market for firearms). A few non-USA automatics have been designed since (FN P90 and HK MP7 are of note), built around very lightweight ammunition and high capacity magazines in very compact platforms; these point to what could have been developed & available domestically, but was stifled for want of a market to experiment in. Should the bans be lifted, we may see some remarkable developments follow pent-up demand.

I enjoy playing sports but watching or following them is boring to me. I played a fair amount of sports in high-school as they were mandated, though you could satisfy the requirement with theater or theater-tech or "mathlete" style competition which I took part in a few times instead of my winter sport.

That said, this may be a strategy for connecting with other people but there's all sorts of small-talk you can make with someone else, but it might involve some human vulnerability on your part. I make non-sports-related small-talk with pretty much anyone unless it's obvious they want to be left alone. I'd rather be talking to women anyways, and "talking sports" doesn't get you all that far.

Sorry, I thought this was well understood:

Counterargument to "the Planck scale is blown up to be visible": The expanding universe itself has (or very probably has) stretched by a factor starting to push into "practical infinity" territory since the Big Bang. (As I recall, common models of cosmic inflation require a minimum of 60 "e-foldings" of expansion in the first moments of the universe's existence: a factor of 10^26 or so, not counting the considerable expansion since then.) By that argument, we ought to be dangerously close to "voiding the warranty" on spacetime already, everywhere in the universe.

As far as I know, the notion that curved space can "enlarge the Planck-scale granularity of spacetime" is not a universal feature of quantum gravity theories. It's not even clear to me what that would mean. (I've only seen one or two string theory talks that suggested such a thing, for instance, and most of the experts in the audience seemed fairly convinced that the idea had no compelling basis in our context. I don't recall whether that's a feature of LQG.)
The issue is expected loss. No one knew what is the expected loss in a crisis. This is why some of the Lehman debt holders actually made money from the bankruptcy. This is why TARP actually made money. It is because there is a substantial difference in asset price while in crisis and not in crisis. The asset price is what is making the bank solvent.

Of course, the central bank (unless you are locked into a monetary union of course) can lend freely during a crisis. However, it must also be careful as to not trigger inflation or worse yet cause people to lose faith with your currency. There is also moral hazard as well but that's more of a soft issue.

The bigger issue is what happens if your bank liability is many times larger than your countries GDP. This was the case with Iceland or Britain. Then you can't print enough money to make your bank whole.

"We have never been to Cleveland, know nothing about it, but you shouldn't live there".

No. No. No. No. No.

Don't move because other people don't think your city is cool enough. Move because you want to.

I live in Northeast Ohio and have never had trouble finding a job. There are plenty of opportunities locally and you always have remote options. OP lives here, has seemingly been there long enough to evaluate it, and should be able to figure out what location makes sense for him!

If you'd be happier elsewhere, or think there are more interesting companies elsewhere, you should move. But people's uninformed opinions need not be considered.

Cleveland's tech ecosystem isn't great but it's improving.

You could try checking out opportunities at younger companies via JumpStart (http://www.jumpstartinc.org/jobsatcompanies.aspx)

Cleveland isn't San Francisco or New York, but it's not BFE, either.

And just for reference on my sports "bonafides" as unimpressive as they may be: I enjoy playing soccer and lacrosse. I varsity lettered in both all four years and was all-state in lacrosse.

Once I hit college I just wasn't tall enough to play at the collegiate level.
In a world of pedants it wouldn't but the same way short genre fiction and multi volume biographies get lumped together in "reading" any sport is enough to give you a couple of sports related conversational gambits.
I ordinarily dislike when people do this ("obligatory xcd: URL"), but that is today's comic. So it is actually relevant. Today.
You do make a very good point that there are opportunities outside of Cleveland -- and Boulder is awesome! -- but Cleveland does have things to recommend it.

My sister-in-law works part-time for a tech company in Cleveland. The cost of living is insanely low (like $400/mo for an entire house in some places) and that allows her to be a full-time artist without needing a full-time job to live. I'd imagine the low cost of living would also make it easier for a freelancer to be selective about clients, should OP choose to take that route.

Many of these Rust Belt and Midwestern cities are becoming centers of hipsterdom. Who would have thought ten years ago that you would see young people moving to Pittsburgh, Detroit, Des Moines, or Omaha to start trendy restaurants and open art galleries? But now I see the reason: it's cheap to live, you can probably afford to buy a house, the public schools are decent, and there's a small community of likeminded people who'd rather do meaningful things than stay on the work treadmill to afford SF or NYC. The same thing is happening in Cleveland, at least from what I've seen.
You're getting a lot of fantastic ideas and advice. You're in the position to cherry pick any that makes sense to you. Best of luck in landing your next gig!

My suggestion is to go to meetup.com and look for groups you'd be interested in. Then spend time mingling with those people. I was going to add tips for how to network effectively, but I don't want to assume - you may already be good at it!

Bingo, Wired, and bravo for writing this!

Let's see: I tell everybody I'm broke. I caught up on ten years of back due tax paperwork. I'm clean, sober and have been for months...just launched free, open source no strings software to end $5 billion in annual American wasted spend on Facebook, Twitter and SEO tools that are mostly junk.

Yep, zero people care. They didn't get a push notification from Google Now, telling them to put down the phone and give to hookupJS. They didn't see Jeff Weiner tweet, "Jeremy, you haven't sent me an SEO weekly report since Yahoo, 2005 - what are the latest numbers?"

Automattic, makers of the best content management software in the world, have a similar philosophy as we do - give it away, free and open source, then chase the value that the open ecosystem creates. Alongside WordPress, hookupJS is designed to be a secure, open source marketing Saas - self hosted, no data leaks and 100% private for business data.

However, the crowd funding yeilded only spam, private comments so far. The LinkedIn messages have been well meaning, but, zero text lines read. The single, solitary fork we got on our repo (software is live, functional and free - on github) practically made me cry.

I don't get it. For some reason, I agree, the feeling in my gut says, "Nobody cares." When I was drinking, I checked into a mental hospital for a few days because I was going nuts, getting stolen from by my former employer and worse.

It is an excellent article. Ignore me, just go read it. Then take a walk, smell the fresh air, and for once in the week, try to figure out if you are inside the Matrix, or if the mesh layer is already controlling you. Put down the hololens, the nerd helmets and the Occulus. Take a look at real life, in 3d. It's awesome.
So he's an entertainer, not an archer? Being entertaining is not a bad thing, but nobody would mistake Arnold in Predator for a real Special Forces operative.
To the opposite extreme, there's also The Stanley Parable. On the surface it's a humorous narrative seemingly about being a cubicle drone, but it's ultimately about the futility of choice.
See pages 179 and 180 of @War by Shane Harris. Since these briefings are clearly more about NSA nest-feathering than actual security, I think it's not so awesome.
The con is not on us. He is not conning the public. He is not trying to get a science foundation grant.

The targets are aging millionaires who lack science education. The US (Florida) is full of people who made millions on the rise real estate and are looking for a new investment. They are old enough to have seen the rise of the internet and think they can get in on the ground floor of the next big thing. They can believe in magic boxes because, for people who haven't seen a classroom in 40 years, Google looks like magic.

Who knows how many "investors" this guy has fooled into handing over their retirement savings. No doubt they are bound by scary non-disclosure agreements and are afraid of speak out. The best person to con is one who, upon realizing they are conned, will not have the resources to fight back. This guy doesn't want Elon Musk's money. He wants you grandmother's.
The OA is very interesting. New educational tools and possibilities are always welcome. However, geogebra is widely used for geometrical investigations on computer at least in the UK.

If you don't mind doing freelance work you will probably find it surprisingly easy. Offer your skills to design shops; they tend to be strong in design but weak in engineering.. the best part is that a lot of them will build their designs into flat html; so you just implement their html and css and do the backend work.

If you can build stuff; you are ready for freelance work.
Can't you serve the main site statically, and have a dedicated page for the proprietary license and Stripe integration?
As a systems programmer for 25+ years I find it impossible a computer will a threat _unless_ it's programmed to do such. I guess that makes me a doubter in general AI. We can do great neural nets, and fantastic task-specific solutions but until someone builds a system that decides to kill people for it's own benefit, I just don't see it happening on it's own.
This is actually pretty fantastic. I loved how quickly I could get an app up and running.

I assume that the paid version has a better app search/browse experience? The demo list, while cool, was pretty long and uncategorized.
Sounds eerily similar to my situation a month ago. I'm 28, grew up in Cleveland, worked mostly with Angular, and was let go the other month too.

I'd start sewing seeds in every direction and see what takes root. Apply to jobs locally, and all over the country. You only have to consider moving if you get an offer. You can try kickstarter or getting an angel investor if you want to try your own software. Freelancing kinda sucks unless you have connections. It's hard to differentiate yourself and get a decent rate if you are just another person online. But again, you can give oDesk a shot and see how it fares.
Was the headline of this edited to change "laid off" to "let go" or am I seeing things?
I've never played the sport beyond a limited-contact flag football league, but I agree with your sentiment. It takes a lot of time to really get to know the game, and if you really like the sport for what it is it's suddenly not so bad to root for a terrible team.

It is kind of a bummer that you rarely get to see all 22 on a broadcast, because the camera stays fixed on the ball carrier. It can be hard to tell if a quarterback is having a bad season because he sucks or because none of his receivers are getting open (though any sports blog will be happy to give you an opinion).
If I could travel in time these are the 7 life hacks I would reveal to myself
The very "needing to get things done" is the appeal - even if the pay is lower (which isn't always the case these days) think of it as investing in your own abilities and skills.

I spent all my days, nights, and weekends out of college working on a doomed startup during the first bubble and I'd still describe it as one of the best experiences of my life. It prepared me for all sorts of experiences since then. I was ideating, researching, designing, building, and even publicly presenting multiple new products for a company that didn't have the staff to specialize in any of those needs.

I've used those skills at companies big and small since then and have worked alongside those who haven't forged their abilities in the pressure-cooker of a startup - I wouldn't change a thing.
When you show overt contempt for sports you are showing contempt for most everybody and that is problem with your social skills.

It's called being a snob. The disdain for working class culture among academics was part of the reason I choose not to pursue a formal higher education. I suspect this overt snootiness keeps many gifted working class kids from participating in higher education.

I grew up working class and was a boxer. I love Ice Hockey, Football, UFC, NASCAR, Motocross, and heavy metal, but I am also an academic and an intellectual. Many highly educated people have told me so, I just don't have the paper to prove it.

My oldest son is highly gifted earning math test scores putting him in the top tenth of one percent and placing 1st in regional Math Masters competitions. He also plays ice hockey so he interacts socially with the 'jocks' and the 'brains' preferring the company of the 'brains.'

Most of his 'smart' friends show contempt for sports which is a social problem since he is an athlete.

When a kids says, "Hockey. Meh. It is a bunch grown men with sticks chasing a black piece of rubber around a sheet of ice" he is saying in effect "What you love is obtuse and low brow and I don't care how that makes you feel." And that is just rude.
Why i rejected a publishing offer
I don't like the message of this post. I do understand (and see) the cultivated disinterest he's talking about, but I would never suggest you try and make yourself like something for the sole purpose of fitting in, ie cultivating disinterest is bad, but so is cultivating this interest.

If you keep and open mind and follow your passions, you'll eventually stumble on something you share enough with others. My disinterest in football is quite genuine, but I enjoy the World Cup and Euro Cup. I also find it hilarious that intellectuals apparently don't go for Heavy Metal, because I'd fall in his "intellectual" category, but spent several years deeply engrossed in Metal and I enjoy the Nordic and Prog subtypes.
There are two ways you can embed that within `turtle`. You can either embed each step as its own concurrent process, like this:

-- Note, the flow is right-to-left, not left-to-right
inshell "bar" (inshell "fgrep ..." (inshell "foo" empty))

Or you can just embed the entire thing within a single `inshell` command:

inshell "foo | fgrep ... | bar"

The reason this works is that the type of `inshell` is:

inshell
:: Text -- Command line
-> Shell Text -- Standard input to feed
-> Shell Text -- Standard output from command

This leads you stream to any shell command's input and read the command's output also as a stream.

The real appeal to a startup has little to do with compensation. It's about "benefits" and intangibles. Obviously these will vary depending on the degree to how "start-upy" your company is but I think you can measure it most by the size. In the extreme example, when you start your own company, you own it all. You want casual Fridays? It's done. You want a remote/results-only workplace policy? It's done. Cubicles, private offices, or wide open desk farms - you pick.

From a developer's perspective, you don't have to support someone else's code (at least for now). It's YOUR code - but it's also YOUR bug when they do come up. It's much less stressful fixing your own bugs then a "senior" developer who's worked there for 15 years and supposedly knows what he's doing but fails to take responsibility.

I previously worked at a large ad tech startup (using that term loosely, they had just gone public and had about 250 people) and it drove me nuts. Particularly, it was the strain of having to work for someone I didn't respect. I left and now run a company with some friends - all of whom I believe to be smarter than I. There is no better feeling than being the dumbest one in the room. That is a luxury rarely afforded at large companies. Invariably, you're going to end up with people at the bottom of the barrel. When you're the owner/boss/hiring manager - you get to pick the people you work with.

TL;DR: Startups aren't about compensation it's about the enjoyment of picking the workplace you want to be in. You don't have to worry about working with people you dislike, because you pick them all!

Edit: Also forgot to mention, I have learned exponentially more in the last 2 years of running my business than I feel like in the rest of my life combined. It's like software development/product management/sales special forces training - you really end up pushing yourself to do more than you thought you were capable of. Mostly because there is no one else to pick up your slack.
Thank you. The name rings a bell, but I will have to check it out.
Show HN: Parallel Programming Frameworks
I've been developing a few parallel and distributed frameworks.

https://github.com/rcorcs/spp
SPP: Structured Parallel Patterns is a framework based on algorithmic (parallel) skeletons. Currently it only supports multithreads, but I intend to keep working to give support to hybrid architectures, such as GPU, MIC, and MPI.

https://github.com/rcorcs/hadoop-watershed
(Hadoop) Watershed is a distributed stream processing system implemented on top of Hadoop YARN, HDFS and ZooKeeper. Watershed is based on a data-flow model (filter-stream DAG) that is used to process data streams.

https://github.com/rcorcs/CloudOS
CloudOS is a distributed "operating system" for data-centers. The basic idea is to develop a high-level abstraction layer over the data-center architecture. This basic layer has been implemented based on the microkernel model, and it offers some data-center primitive operations, so that a distributed file system (DFS) and a distributed process manager (DPM) can be implemented over this basic layer. User's distributed applications are intended to be implemented using the DFS and DPM interfaces (API). User's distributed applications would be Watershed applications, MapReduce applications, etc.
