Want to be a great leader? Assume positive intent

Saturday 18th of February 2017 09:09:33 PM
Open source communities are some of the most passionate organizations I've ever seen. Their members care deeply about the work they do (often voluntarily), and that passion drives incredible innovations. That's no small feat, because open source communities are often collaborating in the face of geographic, cultural, and technological barriers that can lead to unfortunate misunderstandings.And yet open source communities are also extraordinarily resilient. Some of them have found clever ways to refocus their energies and eliminate sources of conflict.read more

How The Linux Foundation is Advancing Next-Gen Internet Infrastructure

Saturday 18th of February 2017 07:15:11 PM
The breadth of the The Linux Foundation (affectionately known as The LF) is often overlooked due to its eponymous name. However, what may not be apparent to the layman is that The LF is providing a true foundation for the next generation of Internet infrastructure by cultivating the biggest shared technology investment in history.

Apple Wants To Stop You Fixing Your iPhone And iPad: Source Says It Will Testify Against 'Right To Repair' Legislation

Saturday 18th of February 2017 03:26:27 PM
Even though the idea seems a no-brainer -- you bought it, why shouldn't you be able to repair it? -- progress has been extremely slow, as successive Techdirt articles have chronicled. One of the most important developments is a number of "Right to Repair" bills that are being considered by various state legislatures. These typically require electronics manufacturers to make service manuals available to the public, and to sell repair parts. The hope is that if even one or two of these are passed, manufacturers will find it simpler to comply nationally. However, an article on Motherboard suggests that the "Right to Repair" movement has a rather surprising enemy.

Organizing your music: Tagging as you rip

Saturday 18th of February 2017 01:32:05 PM
I think that I've always hated filing and organizing stuff. Equally, I always hate it when I can't find something because I haven't filed or organized it well. When it comes to enjoying my music, these two contradicting tendencies tend to show up when I try a new music player that can't figure out how my cover art is stored, can't find the correct cover image online because the album is unusual, or the version I have isn't correctly named.read more

How to install pandom: a true random number generator

Saturday 18th of February 2017 05:54:37 AM
This tutorial explains how to install pandom: a timing jitter true random number generator maintained by ncomputers.org. The built-in Linux kernel true random number generator provides low throughput under modern circumstances, as for example: personal computers with solid state drives (SSD) and virtual private servers (VPS). This problem is becoming popular in Linux implementations, because of the continuously increasing need for true random numbers, mainly by diverse cryptographic purposes.

Apple Will Fight 'Right to Repair' Legislation

Saturday 18th of February 2017 04:00:15 AM
Manufacturers have lobbied hard against right to repair legislation in the past. Last year, a bill headed through the New York statehouse was killed in part due to lobbying from Apple and IBM, among other manufacturers. But nationwide, the legislation appears to have much more momentum this year as more states introduce right to repair bills. Last month, the American Farm Bureau Federation, an influential political organization representing farmers, officially endorsed right to repair legislation.

Linux Lite Among The Best Lightweight Linux Distributions

Saturday 18th of February 2017 02:58:17 AM
Another distro. Yeah, I know. I am getting tired too of all these distros popping out of everywhere. But I am still interested in trying them out. Each and every distro has a different reason for its existence. Today, we will look at Linux lite 3.2. This is neither a distro aiming to be a lightweight distro nor a distro trying to unleash the power of Linux with all apps preloaded. Instead, It tries to strike that perfect balance between them. Now, almost all of the distros aim to do that then, what is so special about this distro which makes it unique. Well, let me introduce to the distro first and I think why it achieved so much more than other distros becomes clear after that.

Understanding the difference between sudo and su

Friday 17th of February 2017 09:20:54 PM
In this article, we will discuss in detail the 'su' command as well as how it differs from the 'sudo' command. The main work of the su command is to let you switch to some other user during a login session. In other words, the tool lets you assume the identity of some other user without having to logout and then login (as that user).

Google's Upspin Debuts

  • Another option for file sharing
    Existing mechanisms for file sharing are so fragmented that people waste time on multi-step copying and repackaging. With the new project Upspin, we aim to improve the situation by providing a global name space to name all your files. Given an Upspin name, a file can be shared securely, copied efficiently without "download" and "upload", and accessed by anyone with permission from anywhere with a network connection.
  • Google Developing "Upspin" Framework For Naming/Sharing Files
    Google today announced an experimental project called Upspin that's aiming for next-generation file-sharing in a secure manner.
  • Google releases open source file sharing project 'Upspin' on GitHub
    Believe it or not, in 2017, file-sharing between individuals is not a particularly easy affair. Quite frankly, I had a better experience more than a decade ago sending things to friends and family using AOL Instant Messenger. Nowadays, everything is so fragmented, that it can be hard to share. Today, Google unveils yet another way to share files. Called "Upspin," the open source project aims to make sharing easier for home users. With that said, the project does not seem particularly easy to set up or maintain. For example, it uses Unix-like directories and email addresses for permissions. While it may make sense to Google engineers, I am dubious that it will ever be widely used.
  • Google devs try to create new global namespace
    Wouldn't it be nice if there was a universal and consistent way to give names to files stored on the Internet, so they were easy to find? A universal resource locator, if you like? The problem is that URLs have been clunkified, so Upspin, an experimental project from some Google engineers, offers an easier model: identifying files to users and paths, and letting the creator set access privileges.

RPi-friendly home automation kit adds voice recognition support

Following its successful Kickstarter campaign for a standalone Matrix home automation and surveillance hub, and subsequent release of an FPGA-driven Matrix Creator daughter board for use with the Raspberry Pi, Matrix Labs today launched a “Matrix Voice” board on Indiegogo. The baseline board, currently available at early-bird pricing of $45, has an array of 7 microphones surrounding a ring of 18 software-controlled RGBW LEDs. A slightly pricier model includes an MCU-controlled WiFi/Bluetooth ESP32 wireless module. Read more

The Year Of Linux On Everything But The Desktop

The War on Linux goes back to Bill Gates, then CEO of Microsoft, in an “open letter to hobbyists” published in a newsletter in 1976. Even though Linux wouldn’t be born until 1991, Gates’ burgeoning software company – itself years away from releasing its first operating system – already felt the threat of open source software. We know Gates today as a kindly billionaire who’s joining us in the fight against everything from disease to income inequality, but there was a time when Gates was the bad guy of the computing world. Microsoft released its Windows operating system in 1985. At the time, its main competition was Apple and Unix-like systems. BSD was the dominant open source Unix clone then – it marks its 40th birthday this year, in fact – and Microsoft fired barrages of legal challenges to BSD just like it eventually would against Linux. Meanwhile Apple sued Microsoft over its interface, in the infamous “Look and Feel” lawsuit, and Microsoft’s reign would forever be challenged. Eventually Microsoft would be tried in both the US and the UK for antitrust, which is a government regulation against corporate monopolies. Even though it lost both suits, Microsoft simply paid the fine out of its bottomless pockets and kept right at it. Read more
