5 open source fonts ideal for programming

Friday 17th of November 2017 10:49:10 PM
What is the best programming font? First, you need to consider that not all fonts are created equally. When choosing a font for casual reading, the reader expects the letters to smoothly flow into one another, giving an easy and enjoyable experience. A single character for a standard font is akin to puzzle piece designed to carefully mesh with every other part of the overall typeface.read more

Why is collaboration so difficult?

Friday 17th of November 2017 06:42:49 AM
Many contemporary definitions of "collaboration" define it simply as "working together"—and, in part, it is working together. But too often, we tend to use the term "collaboration" interchangeably with cognate terms like "cooperation" and "coordination." These terms also refer to some manner of "working together," yet there are subtle but important differences between them all.read more

  • Blockchain Moves Beyond its 'Moonshot' Phase
  • Some reading
    I've complained previously about disliking benchmarking. More generally, I'm not really a fan of performance analysis. I always feel like I get stuck at coming up with an approach to "it's going slower, why" beyond the basics. I watched a video of Brendan Gregg's talk from kernel recipes, and ended up going down the black hole1 of reading his well written blog. He does a fantastic job of explaining performance analysis concepts as well as the practical tools to do the analysis. He wrote a book several years ago and I happily ordered it. The book explains how to apply the USE method to performance problems across the system. This was helpful to me because it provides a way to generate a list of things to check and how to check them. It addresses the "stuck" feeling I get when dealing with performance problems. The book also provides a good high level overview of operating systems concepts. I'm always looking for references for people who are interested in kernels but don't know where to start and I think this book could fill a certain niche. Even if this book has been out for several years now, I was very excited to discover it.
  • Introducing container-diff, a tool for quickly comparing container images
    The Google Container Tools team originally built container-diff, a new project to help uncover differences between container images, to aid our own development with containers. We think it can be useful for anyone building containerized software, so we’re excited to release it as open source to the development community.
  • NATTT – A Modern Multi-Platform Time Conscious Tracker App
    It’s not that there aren’t already a lot of time tracker apps but my conscience wouldn’t let me sleep if I didn’t tell you about NATTT. So grab your cup of whatever you’re probably drinking as we delve into this app a little. NATTT is an acronym for “Not Another Time Tracking Tool”; a free and multi-platform app with which you can keep track of your work and how much you have spent at it.

    Adding to the growing list of changes for GNOME 3.28 are improvements to the Calendar and To Do applications by Georges Stavracas. Stavracas has been reworking the month view of GNOME Calendar and it's looking much better, some applications for Calendar via libdazzle, and more.
  • Compact DAQ systems offer a choice of 12- or 16-bit I/Os
    Advantech’s Linux-ready “MIC-1810” and “MIC-1816” DAQ computers offer 12- and 16-bit analog I/O, respectively, plus 24x DIOs, Intel CPUs, and 4x USB ports. Advantech’s MIC-1810 and MIC-1816 are digital acquisition computers that run Linux or Windows 7/8/10 on Intel 3rd Gen “Ivy Bridge” processors. If the aging CPU is a turn-off, keep in mind that many DAQ applications don’t require that much processing power, and perhaps Advantech’s “entry-level” label for the systems extends to the price, as well. The 165 x 130 x 59mm, DIN-rail mountable systems should also prove useful for environments with limited space.
