Reposting because this is finally out in ghc
"We also show that with Mio, McNettle (an SDN controller written in Haskell) can scale effectively to 40+ cores, reach a thoroughput of over 20 million new requests per second on a single machine, and hence become the fastest of all existing SDN controllers."
"After removing various bottlenecks in our system, SimpleServer scaled to 20 cores and serves nearly 700,000 requests per second. This workload places an unusual burden on the Linux kernel and triggers a bug in Linux;"

How I Came to Write D
The path that led Walter Bright to write a language, now among the top 20 most used, began with curiosity and an insult.
Hasnain says:
"A couple years later, D first appeared on Slashdot and it rapidly started attracting users and collaborators. Turns out, I am hardly a unique person in what I want from a language! D grew dramatically in ambition, with collaborators from all over the world. It wasn't until a few months ago at Dconf2013 that we even knew what each other looked like. (This is one of the greatest aspects of the Internet revolution: You can work successfully with others while knowing nothing about their sex, age, looks, race, religion, language, culture, disabilities, histories, etc. It's as pure a meritocracy as it gets. Only your ideas, contributions, and how you present yourself matter.)"

Heartbleed Bug
The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the I...

wgb.
This is a pretty serious bug. Yay for leaking private keys over the internet.

Haskell for all: Program imperatively using Haskell lenses
Note: the actual limited use of `filtered` that you are making here is perfectly fine. The criterion you are filtering on isn't affected by the action you are taking.
Hasnain says:
"Haskell gets a lot of flack because it has no built-in support for state and mutation. Consequently, if we want to bake a stateful apple pie in Haskell we must first create a whole universe of stateful operations. However, this principled approach has paid off and now Haskell programmers enjoy more elegant, concise, and powerful imperative code than you can find even in self-described imperative languages."

Reading is different online than off, experts say
Our brains, neuroscientists warn, are developing new circuits with a big impact on non-digital reading

Australian Gas Industry Wants to Curb Pay as Cooks Earn $325,000
The Australian government should act to rein in rising labor costs that threaten a potential A$180 billion ($167 billion) expansion of the nation’s liquefied natural gas industry, a lobbying group said.
John Cassidy: Is Surging Inequality Endemic to Capitalism?
French economist Thomas Piketty’s “Capital in the Twenty-first Century” is a sweeping account of rising inequality. Reviewing the French edition of the book, which came out last year, Branko Milanovic, a former senior economist at the World Bank, called it “one of the watershed books in economic thi...
Hasnain says:
This is a review of a highly popular economics book that has been hailed as a revolution in economics.
"Given that inequality is a worldwide phenomenon, Piketty aptly has a worldwide solution for it: a global tax on wealth combined with higher rates of tax on the largest incomes. How much higher? Referring to work that he has done with Saez and Stefanie Stantcheva, of M.I.T., Piketty reports, “According to our estimates, the optimal top tax rate in the developed countries is probably above eighty per cent.” Such a rate applied to incomes greater than five hundred thousand or a million dollars a year “not only would not reduce the growth of the US economy but would in fact distribute the fruits of growth more widely while imposing reasonable limits on economically useless (or even harmful) behavior.”
