The stdlib rand() function on unix has a global lock around it provided by many versions of Linux. As such, if rand() is called in performance critical parallel code, performance will tank as each thread or process attempts to acquire this

From github: The algorithm is iterative deepening depth first alpha-beta search. The evaluation function tries to minimize the number of tiles on the grid while keeping same/similar tiles in line with each other. This basically means h

As a gut check, if you're solving some replication problem and you'd consider using Paxos to solve the problem, be /very/ wary and reason extremely carefully about why your weaker solution will provide the same guarantee

The US hasn't adopted EMV because it isn't necessary. EMV was created because in Eastern Europe many businesses didn't have sufficiently reliable phone and internet connections to validate credit cards -- in the US we have no

1. I'm thinking of it being connected with Google Play. 2. Once you've increased the scope beyond the apps on the device, work needs to be done to show the most relevant and useful actions. 3. Enabling flows like: - Take file from

An Android phone is my primary device. A few key issues for me: 1. No app discovery -- I want to find out about apps that can work with my content. 2. Action curation -- I want to see the actions that other people think are most useful when

This is a good start -- http://x-callback-url.com/ is a standard and listing for apps that support it. The biggest problem is that there is a limited amount of data that you can transfer in a URL (about 80KB I believe) so e

Yes. The Ubuntu Phone / OS is a interesting byproduct of this idea.

There's a difference between the performance you want in your kernel and the performance you need sharing to Facebook. It seems like creating monolithic mobile apps is premature optimization.

Ah, yeah. I was talking about iOS in particular. Android intents are pretty sweet -- a couple the missing bits to make them great in my mind are -- App discovery: tell me about apps that can use my content if I don't have any? -- Acti

We think that the key is to provide a limited and controlled interface between the apps (which is what we're trying to do). We'll see how it goes :-)

Intents are useful, but could be better. A standard way to hook into the Facebook app is fine for Facebook but what about when the space is more fragmented? Should app authors have to integrate with every document viewer or Mail App?

It seems that what you actually want is for CoffeeScript to have configurable backends. I agree that it's silly to generate IE6 compatible code when I know that I'm targeting node. This isn't a reason not to use CoffeeScript

I'm especially excited about the race detector. It looks like a practical implementation of http://cseweb.ucsd.edu/~savage/papers/Sosp97.pdf . Always exciting to see research coming up in practice!

For a while, Linked in was present a password input box that looked like "You failed to login, try again" at a glance, but in reality it was asking for your email address and password. From that point, they could read your email and extract

I became irritated when quick sort was claimed be O(n^2). Not only is that not true in practice, it's just wrong for all but the simplest implementations of the algorithm. With minor tweaks to the selection of partitions, quick sort can be
