Using Names Pipes and Process Substitution in Bioinformatics | vince buffalo
It’s hard not to fall in love with Unix as a bioinformatician. In a past post I mentioned how Unix pipes are an extremely elegant way to interface bioinformatics programs (and do inter-process communication in general). In exploring other ways of interfacing programs in Unix, I’ve discovered two great but overlooked ways of interfacing programs: the named pipe and process substitution. Why We Love
Another look at MySQL at Twitter and incubating Mysos
While we’re at the Percona Live MySQL Conference, we’d like to discuss updates on how Twitter uses MySQL, as well as share our plans to open source Mysos, a new MySQL on Apache Mesos framework. MySQL at Twitter Since Twitter was founded, MySQL has been one of our key data storage technologies. We store data in hundreds of schemas and our largest cluster is thousands of nodes serving millions of qu
On Arrays.fill, Intrinsics, SuperWord and SIMD instructions
{This post turned rather long, if you get lazy feel free to skip to the summary} Let's start at the very beginning, a very good place to start... My very first post on this blog was a short rant on intrinsics, and how they ain't what they seem. In that post I made the following statement: "intrinsic functions show up as normal methods or native methods" Which is correct. An intrinsic function is a
Pistachio: co-locate the data and compute for... | Yahoo Engineering
Pistachio: co-locate the data and compute for fastest cloud compute https://github.com/yahoo/Pistachio is a distributed key value store system. Data can be replicated with n replicas with strong consistency guarantees. Up to (n-1) failures can be tolerated. It’s being used as the user profile storage for large scale ads serving products within Yahoo. 10+ billions of user profiles are being stored
Yahoo Cloud Object Store - Object Storage at Exabyte Scale
Yahoo stores more than 250 Billion objects and half an exabyte of perpetually durable user content such as photos, videos, email, and blog posts. Object storage at Yahoo is growing at 20-25% annually. The growth is primarily driven by mobile, images, video, and user growth. Yahoo is betting on software defined storage to scale storage cost effectively along with the durability and latency guarante
Fearless Concurrency with Rust | Rust Blog
The Rust project was initiated to solve two thorny problems: How do you do safe systems programming? How do you make concurrency painless? Initially these problems seemed orthogonal, but to our amazement, the solution turned out to be identical: the same tools that make Rust safe also help you tackle concurrency head-on. Memory safety bugs and concurrency bugs often come down to code accessing dat
RE2/J: Linear-time regular-expression matching for Java
Today we’re announcing the public release of RE2/J: a pure-Java implementation of the popular RE2 regular expression library. Although RE2/J is not always faster than java.util.regexp, its running time is always linear in the size of the input. Thus when matching larger inputs, especially against patterns containing a high degree of alternation, RE2/J may be dramatically faster. With a backtrackin
