Introduction gevent is a coroutine -based Python networking library that uses greenlet to provide a high-level synchronous API on top of the libev event loop. Features include: Fast event loop based on libev (epoll on Linux, kqueue on FreeBSD). Lightweight execution units based on greenlet. API that re-uses concepts from the Python standard library (for example there are Events and Queues ). Cooperative sockets with SSL support » DNS queries performed through threadpool or c-ares. Monkey patching utility to get 3rd party modules to become cooperative » gevent is inspired by eventlet but features more consistent API, simpler implementation and better performance. Read why others use gevent and check out the list of the open source projects based on gevent . gevent is written and maintained by...
Writing Software, technology, sysadmin war stories, and more. Monday, November 24, 2014 init is a pretty big deal on a Linux box. If you manage to kill it, the machine panics. Everything stops, and if you're lucky, it reboots by itself a few seconds or minutes later. Naturally, you'd like it to be stable and robust so that your machine doesn't go down. What if I told you I found a way to kill the "Upstart" init in RHEL and CentOS 6 with just a bunch of "touch" commands? Yep, it's true. You can even reproduce it in qemu. In fact, I had to do it in there in order to get these screenshots. Step 1: Create a new directory under /etc/init. I called mine "kill.the.box". Step 2: Fill that path with a few hundred or thousand files. I used 'touch $(seq 1 1000)' but do it however you like. Step 3: Kick off a bunch of changes to those files in parallel. As you can see her...

CentralNotice Pareidolia From Wikipedia, the free encyclopedia Jump to: navigation , search A satellite photo of a mesa in Cydonia, often called the Face on Mars . Later imagery from other angles did not contain the illusion. Pareidolia ( / p ær ɨ ˈ d oʊ l i ə / parr-i- DOH -lee-ə ) is a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant . Common examples include seeing images of animals or faces in clouds, the man in the moon or the Moon rabbit , and hearing hidden messages on records when played in reverse. The word comes from the Greek words para (παρά, "beside, alongside, instead") in this context meaning something faulty, wrong, instead of; and the noun eidōlon (εἴδωλον "image, form, shape") the diminutive of eidos . Pareidolia is a type of apophenia , seeing patterns in random data. ...

CentralNotice QR decomposition From Wikipedia, the free encyclopedia Jump to: navigation , search In linear algebra , a QR decomposition (also called a QR factorization ) of a matrix is a decomposition of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R . QR decomposition is often used to solve the linear least squares problem, and is the basis for a particular eigenvalue algorithm , the QR algorithm . If A has n linearly independent columns, then the first n columns of Q form an orthonormal basis for the column space of A . More specifically, the first k columns of Q form an orthonormal basis for the span of the first k columns of A for any 1 ≤ k ≤ n . [ 1 ] The fact that any column k of A only depends on the first k columns of Q is responsible for the triangular form of R . [ 1 ] 1 History 2 Definitions 2.1 Squar...
