Look into merger arbitrage. Its a huge area that has spawned many hedge funds, including the one I work at.

The difference is the market saying the deal might fall apart.

Some issues with shorting:

- very limited borrow, not much more than 2 million.

- very concentrated borrow.

- the spot rate for us to borrow is 2-3%, but with such a small amount of float avaiable to borrow the chances are high that you won't be able to get any and you won't pay anything close to 3%

Here is a good primer:

That's really an argument for buying index funds, since the costs and fees of buying and selling random stocks would eat away any profits very quickly.

(Even just buying and holding truly random stocks is still less likely to be a better investment strategy than index funds after taxes and fees are taken into account, let alone the volatility).

A question for the RE insiders here. What restrictions are there for building services off Redfin/MLS and Zillow listings?

Am I allowed to blog about listings or do I need to be an agent to use image and listing data? I get mixed opinions elsewhere about whether this falls under fair use.

I notice that Redfin provides OpenGraph annotations but the TOS disallow sharing. Am I permitted to share on Facebook, Pinterest, etc? What about on other websites? Is it possible to build a vertical search engine based on these details?

I'm slightly colorblind and have had a hard time on the same level as the parent poster. Greyscale colorblindness (i.e. absence of color receptors) is extremely rare. PopCap does a colorblind safe mode (for zuma, peggle, etc), so did EA for Battlefield 3.
It might not be the best solution, but it's good enough for 80% of the colorblind.
There is a downside, a midway solution, although more realistic, reduces attention on the bigger problem, the rest of the colorblind population would be less catered to, but imho that already is the status quo and will be for the foreseeable future
I've know someone with a Physics PhD who is working at Microsoft in development.
I recently wanted to give a command-line program the ability to wait for and respond to keypresses instantly, without the user having to type Enter. It sounded simple enough. Here's what you have to do to set this up:

// headers for terminal control
#include <termios.h>
#include <unistd.h>

// global variable
struct termios saved_attributes;

// prototype of atexit callback
void reset_input_mode (void);

// --- inside main()

// local variable
struct termios termios_data;

// tell stdio not to buffer output
setvbuf(stdout, NULL, _IONBF, 0);

// incantation to the terminal
tcgetattr(0, &termios_data);
saved_attributes = termios_data;
termios_data.c_lflag &= ~(ECHO | ECHONL | ICANON | IEXTEN);
termios_data.c_cc[VMIN] = 1;
tcsetattr(0, TCSANOW, &termios_data);

// set atexit callback so we can restore the prior terminal mode upon exit
atexit(reset_input_mode);

// --- outside main()

// implementation of atexit callback -- restores terminal to prior mode
void reset_input_mode (void)
{
tcsetattr (STDIN_FILENO, TCSANOW, &saved_attributes);
}

Now, you can read input one byte at a time (with, e.g. getchar(3)) and output appears instantly.

I love how they don't take backwards compatibility so seriously. A lax attitude to backwards compatibility means they can actually have the syntax get less bad over time, instead of becoming C++. Scala does have some less-than-obvious things that need to be fixed.
Goodbye C++. Hello F#?
There may be an elephant on the table. Some people are not as aggressive at promoting their company, their vision. These people will probably not convince a VC to part with money.

A "crossover" is the industry term for what amounts to a station wagon with SUV-like styling.

"Minivan" and (non-"crossover") "SUV" are two names for what amounts to a station wagon built on light-truck frames -- with originally somewhat different demographic targeting in the marketing, but eventually the "SUV" class's marketing broadened to subsume the target that minivan marketing had been focussed on -- originally to fit loopholes in passenger safety and efficiency regulations (which have since largely been closed, hence, the emergence of the "crossover", which was a reversion since the expense of the regulatory dodge was no longer particularly useful.)
Facebook didn't experiment with "mood manipulation" any more than OKC. Facebook experimented with changing the site layout and which content and how much to show. Exactly the same stuff as all sites test.

Facebook did theorize that the changes it was making would affect people's moods in a certain way. That might make it sound like intentional mood manipulation.

But OKC's changes also affected people's moods. More than Facebook's, I would guess.

All these sites are constantly experimenting on humans. That's what changing the site content means. Everything that affects us affects our moods and everything else.
> I...decided against that because a buyer's agent is legally required to represent your best interests as the buyer whereas the seller is representing the other party

This actually depends on if your state's regulations permit dual agency or not; some states, e.g. Massachusetts, permit one agent to represent both parties. Other states, like Florida, forbid it due to the potential conflict of interest.

Either way, though, avoiding dual agency is probably a good call. It's fraught with potential problems, and even if the agent cuts perfectly square corners, the quality of representation will still suffer since the agent must keep both parties in mind at all times.
Ask HN: Good/bad idea to hire programmers from coding bootcamps?
Have you hired people from one of those 3-month coding bootcamps? I'm considering hiring someone who just graduated from one of the better ones. Should I be worried??
Yes, but CloudFormation doesn't have Terraform's concept of an "execution plan"[1], which tells you what Terraform will do, before it does it. It is very easy with CloudFormation (especially as they get larger and more complex) to run into cases where CloudFormation unexpectedly destroys and recreates a resource, something that would never happen in Terraform because you would see it before it happened in the plan.

There are more comparisons to CF here: http://www.terraform.io/intro/vs/cloudformation.html

Although not specifically Linux:

The bad thing about this idea is that it wouldn't be reliable for the user's eye because of the variation of color representation across screens.

The good side is that it would be a correct representation of the accuracy of color recognition of the system screen-eye, which is much more relevant from a design perspective.
Over the last 25 years lead has been phased out of paint, automobile gas and plumbing fixtures, but aviation gasoline, or "Avgas" remains leaded and is the number one source of airborne lead in the United States [0].

It frustrates me that the primary source of airborne lead stems from a mostly recreational source. Most planes that use Avgas are privately owned piston-engine/prop planes.

Seems usable and I'm excited to try it out. I like the idea of "execution plans" and the declerative way of setting up the architecture.
The problem is that the alternative is reading on your computer or reader - which sucks (for many) compared with a real book. For me I remember things more clearly when I read them in physical books because the information exists in a "space" - I remember reading something, pick up the book and flip there. I can recall things by remembering what was around them in the book. The tactile-ness works for my brain.

I totally agree they aren't worth destroying trees for (I only buy paper books for topics that are more age-resistant) but I get why people still buy them.
On the other hand I would be quite hesitant to hire a developer to build a customized video player for tens of thousands of dollars if he was going to go on and sell that same code to others for $200 a pop.
I think it's pretty obvious the line isn't anywhere close to being appointed CEO of an organization politically charged enough to have a manifesto.
Up until a few weeks ago, we had the whole issue clickable. It'd toggle the select checkbox for bulk actions across multiple issues/pulls. However, we opted to skip that as missing a click on say a milestone name, user avatar, or label would then toggle that issue's selection. It'd be even worse if the accidental clicks sent you to a specific issue as you'd get inadvertent loads and have to go back.

Bottom line? Too frustrating for common use, so we skipped it.

Yes. Think Apple. They weren't the first Apple, and they can't touch other Apple entities that have been around before the existence of Apple (ie. Apple Bank in NY). However, anyone that uses the name Apple, or a logo similar to that of Apple's, after Apple's original use, they can go after.

Thanks, I referenced Firesheep in the grandparent. FS is currently very broken. I still couldn't get it to work after downloading the source and making some changes.

As a guy, this... this is pretty much it. I tried OKC for around half a year, starting out doing just that. After the first half I just said "Fuck it" and switched to bullshit two sentence intros that were fill in the blank types. My response rate was practically the same.

Thinking about it now, it seems like the numbers game recruiters play. Send out a lot of semi-decent introductions and hope for a response or two. Your best bet is getting out there and "networking", but in lieu of that, sending out a deluge of messages is the next best, albeit shitty, thing.

I'd be interested in hearing how women deal with the deluge of introductions and what makes them decide to respond to someone. Is it the intro? The profile picture? Do they read the person's bio or use that compatibility meter?
"Make your own decisions" is good advice, but I think the main question is whether there exists any reliable means of distinguishing the good contrarian vs. bad contrarian investments--or whether it's just luck. The title seems to imply that the answer might be just luck.

On the website for my local NPR station (91.7 KXT, Dallas/Fort Worth) they have a playlist that shows recently played songs and the only option to "Buy Song" takes you to iTunes. I'm assuming they get a share of the revenues from songs purchased and I wish they would link to Amazon or Google Play instead so I could help support. They've introduced me to a lot of good bands and I buy a couple songs I hear on the station a week.
I have been developing a tool that is almost the same called 'ozone.io'.. It leverages CMT tools such as puppet, ansible, chef. Not by writing plugins, but rather have users write or extend scripts called 'runners' that install and execute the CMT tool per node. You can checkout a prototype chef-solo runner at https://github.com/ozone-io/runner-chef-solo.

Parallel deployment of multiple clusters is also covered. It too is handled by a directed acyclic graph based on dependencies on other clusters. I am on my own and I am writing it for my thesis which will come out pretty soon.

It is created as an engine that expects cluster state. A sample input file can be seen here which is the only state you need to launch something. https://gist.github.com/wernerb/35a06e08a4d4e6cb02aa

The whole thing works declaratively, so it converges your infrastructure to the desired state. By increasing the nodes for 'smallweb' it will undergo the steps defined in the cluster lifecycle. It will then also update the configuration of the nginx load balancer.

As you can see each cluster is pinned to a provider/instanceprofile, and one of the things I am adding are affinity rules so the cluster deploys to multiple locations/providers.

It is not ready to be opensourced but if any wants to see, contribute or see more I can give view access.

What do you think?
Sure, but it still requires the same kind of prescored lid; even with a key, I don't think that general design approach scales up very far while still not being too much of a hassle for consumers to bother with if there are competing products that are more convenient to open.

Interesting article. I bought a CSA share with a local urban farm in St Paul and Minneapolis. I thought about soil and air contaminants when we made the purchase, but eventually decided to do it anyway. This article reassures me a bit that it's fine, especially since we always wash our veggies well.
That's what I figured. Consider that the volume of a tuna can is probably limited to roughly 1 meal worth. If you made it with optimal dimensions, based on material usage, then the diameter might be too small for a normal can opener, and it might be too narrow to get all of the tuna out easily.
So investing at the seed stage is random. I'm surprised that VCs don't help new companies more in the early stage to mitigate some of the common failure patterns, for example the list PG had in 2006. Perhaps couples counseling for YC founders? Every little bit reduces investor risk even a little.

I'm willing to bet that Facebook has always done this with their data as well. You have to, in order to determine not just if your algorithms work, but whether they should work and what they should do.

Also, Facebook didn't 'hide it from their users' so much as 'not tell anyone they were doing it'. And for the average OkCupid user, I'm willing to bet that 99% of them have no idea this sort of thing happens. They log onto the site, do some stuff, and then leave.

Personally, I was as surprised by the idea that OkCupid outright lied about compatibility scores to see what was up as I was about the results, but it doesn't bother me, and I'm the type of person who's read all their blog posts anyway.
I used to make Android themes back in the day. I would wait until a game got really popular on iOS and count on Android users checking the Android app store for the same titles. I'd sell an "Angry Birds" phone theme for 99 cents. Many Android users werent that technologically savvy and thought they were buying the actual game. This went on for about 6 months. I was making serious money. Eventually they caught on and I was banned from the store. I was a kid and doing something a bit douchey but I definitely understand banning me.

This guy doesn't quite seem to feel the same way.

Great answer, thanks for explaining this! I'm curious about how much this approach differs from the one pursued by Javascript, which seems pretty similar to me.

to be clear: i don't think seed investing is random. far from it. i just think it's really important to think independently and take the time to really get to know founders and understand businesses instead of just following other investors.
it's actually really hard to tell what the passenger rating is. It only flashes on the screen momentarily. Lyft, on the other hand shows it up until you pick up the passenger. This is helpful, one time I called a passenger as a courtesy and got a really really belligerent tone, and i noticed his passenger rating was really low, and so I told him, "sorry, not worth the effort".
That's sounds like a great feature; you are correct, one of the biggest pain points with Cloud Formation is the need to devine which actions will be taken in response to changes.
I'm trying to reproduce this on a macbook. I'm a developer, not a networks guy so please excuse me for not knowing the basics!

After doing `sudo tcpdump -In -i en0 -s 2048 -A dst i.instagram.com`, and using every instagram feature from my iPhone, nothing happens in the terminal.

```

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on en0, link-type IEEE802_11_RADIO (802.11 plus radiotap header), capture size 2048 bytes

```

I try running with -v and -vv, but no difference (except it doesn't suggest running in verbose more).

After hitting C-c to stop the program, it outputs

```

^C

0 packets captured

29816 packets received by filter

0 packets dropped by kernel

```

So there's a lot of things being captured, but the filter does not catch my Instagram activity. I'm logged in there, refreshing, getting images, getting followers/following, etc.

If people mean "the ability to freely speak about something without being harshly punished for that speech, regardless of who does the punishing" when they say "free speech" then they have no idea what they are talking about, and they should be corrected. Such a thing does not exist, and it makes no sense. You can not expect to freely bad-mouth your employer or make remarks that go against an organization's beliefs without any repercussions from the employer or organization.
