Some of Greenland's coastal ice will be permanently lost by 2100: Glaciers and ice caps can no longer capture meltwater. -The glaciers and ice caps that dot the edges of the Greenland coast are not likely to recover from the melting they are experiencing now, a study has found.
Researchers report in the current issue of the journal Nature Communications that melting on the island passed a tipping point 20 years ago. The smallest glaciers and ice caps on the coast are no longer able to regrow lost ice. The current study suggests that the melting of Greenland's coastal ice will raise global sea level by about 1.5 inches by 2100. The find is important because it reveals exactly why the most vulnerable parts of Greenland ice are melting so quickly: the deep snow layer that normally captures coastal meltwater was filled to capacity in 1997.
That layer of snow and meltwater has since frozen solid, so that all new meltwater flows over it and out to sea. See How This House Was 3D Printed in Just 24 Hours. 3D printing is being used to produce more and more novel items: tools, art, even rudimentary human organs. What all those items have in common, though, is that they’re small.
The next phase of 3D printing is to move on to things that are big. Really big. Like, as big as a house. Music making with tools for Linux. Do you think music software is only the domain of expensive proprietary software?
Think again. There are literally hundreds of applications out there designed by, and for, those with a musical bent. Music projects, including many projects specifically for the Linux operating system, flourish in the open source community as musicians take to coding to produce tools to make their lives easier.
Raspberry Pi VPN Access Point - Pi My Life Up. In this Raspberry Pi VPN access point tutorial, we will be exploring how to setup a VPN for use with a WiFi Access point.
This tutorial is pretty straight forward and once setup you can leave it alone with only needing do maintenance if something goes wrong. This tutorial provides a quick and easy way of running any device you want through a VPN even if it doesn’t support any VPN software. As all you need to do is connect that device to your Raspberry Pi wireless access point and all its traffic will be automatically routed through a VyprVPN tunnel. Tips for troubleshooting with Linux. Although it would be nice to believe that cars, home theater systems, computers, and Linux never break, the reality is that they do.
Many people have no problems with Linux, but those who do want the best information and guidance possible. You can obtain professional help from a number of places. For example, if you purchased Linux from a major vendor such as Red Hat, you are entitled to some level of service from that vendor. AsciiDoc for open source documentation. I discovered AsciiDoc while writing Learn Linux in a Month of Lunches.
AsciiDoc is a fantastically thorough markup language for writing books—think Markdown, but with more options, such as sidebars, notes, and tables. AsciiDoc lets you just type, with simple syntax controlling the formatting. When I first started writing my book, I was using Word style sheets with LibreOffice. Manning, my publisher, offered .odt versions for OpenOffice, but I had trouble getting the styles to work. Ironically, I wound up using the Word .docx template, which worked best with LibreOffice.
A look at the Raspberry Pi Sense HAT. In my first article in my series, I wrote about the Astro Pi competition, an opportunity for UK school students to have their coded experiments run in space.
We're getting closer and closer to the launch date of December 15, when British European Space Agency (ESA) Astronaut Tim Peake will embark on his six-month mission, Principia. He'll be conducting scientific experiments and engaging with young people in educational outreach activities. As part of this, he's taking up two Raspberry Pi computers in purpose-built flight cases, each with camera modules and sensor boards attached. These will be running Python programs written by the Astro Pi competition winners. Learn a Bash script for a simple, user-friendly command-line calculator. If you're reading this article, odds are good that you're not only familiar with the command line on your computer system, but that you're quite comfortable using it to the exclusion of the graphical interface.
I understand—I've been using the command line since that was the only option in the computing world, and even contributed code to BSD Unix, back in the day. There's a lot about modern GUIs that make them superior, but in terms of power, speed, and flexibility, the command line still rocks, and even more so if you can type quickly. How to Download Your Favorite Website for Offline Access. Do you want to access your favorite website without internet?
Today we will discuss how you can download a website for offline access. With the help of this trick, you will be able to browse any website without Internet Connection. There are many tools which can perform this task. HTTrick is one of the best website copier you can use in your Window PC. Follow these steps to download a website for offline viewing using HTTracks: Building Your WorkBench. After 11 hours of work (including the trip to Home Depot to buy the lumber), this is what I’ve upgraded to.
No more using the kids’ toys in the garage as temporary sawhorses! I can use the table saw, planer, and router in place, and I’ll be mounting a drill press on top too. The jointer will be stored underneath, since I don’t use it that often and it’s not that heavy. Building a nice workbench is a very important task. Build Your Own Sidekick-Inspired Mobile Raspberry Pi Computer.
Do you long for the days of your Sidekick, arguably one of the best-worst-greatest phones to ever hit the market?
NODE shows you how to build a mobile Raspberry Pi machine that should help with that longing as long as you don’t care about the actual phone part. He uses a new Raspberry Pi Zero W, a 3D printed case, and an old iPhone 5 sliding keyboard case. It’s all soldered together to add in a full-size USB port that still includes access to the HDMI, a battery charging port, and more. NODE has been on a quest to make the perfect portable Pi for a while, his first iteration used a Raspberry Pi A+, while his second upped the ante with a Raspberry Pi 2 and is still to this day one my favourite Raspberry Pi projects. I haven't gotten around to actually making one for myself, and now I’m not sure which of these two I want to try and make for myself first. Building An Earth Bag Round House For Less Than $5,000…
This beautiful earth bag home contains 450 ft² of space and was built for less than $5000. Recycled or salvaged materials were used wherever it was possible (i.e. the door and flooring). The rounded shape provides great stability for the entire structure, and two rows of concrete bags reinforced with barbed wire provide a solid grounding. Here’s a step by step of the build… PowerSpout - Water goes in, Power comes out. How to have a Linux home server on the cheap. Ask any Linux enthusiast, and they’ll tell you how awesome an operating system Linux can be. (Well, except Bryan Lunduke, who will say it sucks before he says it’s awesome.) For the desktop user, the freedom from worry about most viruses is a big plus, and not spending $100 upgrading Windows is a big plus too. Raspberry Pi OwnCloud: Your Own Personal Cloud Storage - Pi My Life Up. In this project we’re going to make a Raspberry Pi Owncloud server this can act as your very own personal cloud storage.
As the protection of your privacy becomes harder and harder you may be thinking of moving your files to a private cloud storage. If this is the case the then this tutorial is perfect for you. It is important to remember that since your data will be stored on your local network you will end up with using more bandwidth if uploading and downloading files from outside your network. In this tutorial will take you through everything you need to know to get it setup and accessible. The DIY Smart Saw.
Build Your Own Sidekick-Inspired Mobile Raspberry Pi Computer. DeepMind Open Sources Sonnet Library To Make It Easier To Create Complex Neural Networks.
