Tweaking Tweetbot - All this June 6, 2015 at 2:24 PM by Dr. Drang I bought Tweetbot for the Mac a couple of years ago with the expectation that I’d retire Dr. Twoot and just go with Tweetbot on both my phone and my computers. It didn’t work out that way, but maybe now it will. The problem has always been with the way Tweetbot looks. Adventures in financial and software engineering Several years ago I read an extremely interesting paper, "How to write a financial contract", by Simon Peyton Jones and Jean-Marc Eber. This paper presents a domain specific language for describing financial instruments such as bonds, options and futures. This subject is bound to be interesting to those in the financial industry; however, the ideas are explained so beautifully that the paper should inspire all programmers. Many academic papers are jargon filled and difficult to comprehend for non-experts. Peyton-Jones and Eber (and Julian Seward in a earlier version of the paper) take the time to motivate the problem and craft explanations.

One simple thing you can do to make yourself an amazing software developer You’re getting there with the technical knowledge. There’s always more to learn, but you’re on top of your game, you know how to get started and you know how to move on when you’re stuck. You’re moving fast with regards to dealing with projects. Estimating, managing tasks, dealing with requirements. Linux Performance Analysis in 60,000 Milliseconds You login to a Linux server with a performance issue: what do you check in the first minute? At Netflix we have a massive EC2 Linux cloud, and numerous performance analysis tools to monitor and investigate its performance. These include Atlas for cloud-wide monitoring, and Vector for on-demand instance analysis. While those tools help us solve most issues, we sometimes need to login to an instance and run some standard Linux performance tools.

PaperLike: 13.3″ E Ink Monitor by Dasung Tech (Videos) One of the coolest new E Ink contraptions to be shown off at CES 2015 was a 13.3″ E Ink monitor that connects with computers and laptops via a USB cable to provide a secondary display. The device is called the PaperLike and it’s being made by one of E Ink’s partners in China by the name of Dasung Tech. The PaperLike uses a 13.3-inch E Ink Fina screen that has a resolution of 1600 x 1200 (150 ppi). Fina is E Ink’s glass-based display and is different from what’s on the 13.3-inch Sony DPT-S1 PDF Reader, which has a flexible plastic-based screen.

Be smart about it with these steps. Back It Up How to JIT - an introduction - Eli Bendersky's website When I wrote the introductory article for libjit, I aimed it at programmers who know what JITs are, at least to some extent. I did mention what a JIT is, but only very briefly. The purpose of this article is to provide a better introductory overview of JITing, with code samples that don't rely on any libraries. Defining JIT

iDraw - Mac Illustration and Graphic Design We’re very excited to announce that Indeeo has been acquired by Autodesk, and that iDraw is now Autodesk Graphic. From the launch of the very first version of iDraw with the original iPad, our mission has been to create a powerful yet easy to use vector illustration application for everyone. iDraw for iPad was designed from the start to bring the full toolset found in desktop illustration applications to the iPad, and the Mac version soon followed creating seamless workflows between Mac and iPad. Following on this same goal, today we’re proud to introduce a brand new iPhone version of Graphic - a full-featured illustration application right in your pocket. We’re also launching free updates for Mac and iPad with many great new features, including support for El Capitan and iOS 9, along with pressure-sensitive drawing and haptic feedback on Mac.

Getting started with libjit – part 1 libjit is a very interesting project. It's a C library for generating executable machine code at runtime. As such, it can serve as a back-end of a JIT compiler. libjit was originally created as part of the larger DotGNU project (portable .NET runtime). Remembering RSS and linking Remembering RSS and linking I was talking with my first-year students about Hossein Derakhshan's important essay on the not-so-slow destruction of the open web. I'd guess the average age of the students was 19, and they had no direct experience of the link-rich, user-organized public space we shared widely just a few years ago. They did not easily see how far the decay has gone because they have never used an RSS reader to keep up with a few dozen active sites that matter to them.

Active Isolated Stretching Philosophy & Techniques » Stretching USA The Active Isolated Stretching (AIS) method of muscle lengthening and fascial release is a type of Athletic Stretching Technique that provides effective, dynamic, facilitated stretching of major muscle groups, but more importantly, AIS provides functional and physiological restoration of superficial and deep fascial planes. Over the past few decades many experts have advocated that stretching should last up to 60 seconds. For years, this prolonged static stretching technique was the gold standard. However, prolonged static stretching actually decreases the blood flow within the tissue creating localized ischemia and lactic acid buildup. This can potentially cause irritation or injury of local muscular, tendinous, lymphatic, as well as neural tissues, similar to the effects and consequences of trauma and overuse syndromes.
