Reddit: Beginners guide to OpenStreetMap

Wednesday 24th of January 2018 10:18:57 AM

Hello /r/linux,

I know that a lot of you are interested in OpenStreetMap. So I thought it would be nice if I would post a short intro to OSM. Hope you like it.

What is OpenStreetMap?

Simply Wikipedia for maps. OpenStreetMap (OSM) is a map that anyone can edit, similar to Wikipedia, but not the same. Everything you see in the world could be in one map. Open-source, usable for everyone. Wheelmap helps people with disabilities and Kurviger can show routes for motorcyclists that are more curvy and outside of residential areas. There are many more examples how the data you contribute is used (just scroll down).

How is it different from Google Maps?

Google Maps is great but not open data. Are you allowed to print it commercially? No. Can you take the map data and create your own routing engine? No. Create your own map style from their data? Nope. Google has invested a lot of money to get all those building shapes, lakes and other geographical information. They won't share it and that's their right. But we believe that all of this information should be available in one big database free for everyone.

Isn't mapping complicated?

No. The world of OpenStreetMap consists of three basic elements. Points (nodes), lines (ways) and areas. They get their values through so called tags (like name=Golden Gate Bridge). For example a church could outlined as an area and tagged as:

name=Church of our Lady building=church amenity=place_of_worship religion=christian denomination=evangelical

We use nodes for shops, small features like fountains or bicycle repair stations. Ways for roads, paths, small waterways. Areas for forests, buildings and ponds.

How can I edit?

We have two main editors for armchair mapping. iD and JOSM. JOSM is an advanced standalone editor but it's better to have some experience before you begin mapping with it. I will focus on the browser based one called iD, which has a great tutorial. Another good learning source is LearnOSM.

Some tutorial videos:

To add things with your mobile phone you can use OsmAnd or Maps.me, which also displays the map you help to create. StreetComplete for Android to add information to existing stuff on OSM.

Some examples where your contributions appear:

Maps

  • HikeBikeMap - hiking and cycling routes can be overlayed on the upper right
  • OpenTopoMap - same as above, Topographic map, has contour lines
  • Waymarked Trails - Hiking - Hiking trails, "clickable", .gpx Download, background can be changed to OpenTopoMap
  • Waymarked Trails - Cycling - same as above for cycle ways
  • OpenSeaMap - free nautical database

  • List of apps for Android and iOS

Routing Services

  • OpenRouteService - car, cycle and pedestrian routing with a lot of options, shows surface and type of used roads
  • Brouter Web - fast router,shows height profile, where routing table can be changed by yourself
  • GPSies - create tours for different transport modes, press "follow roads" to get routing feature, elevation profile, lot of map layers
  • Kurviger - a route planner that prefers curvy roads and slopes, but avoid cities and highways, automatic round trips based on a given length
  • Cycle.travel - a map made for cyclists, which has a routing and roundtrip feature, created by /u/doctor_fegg

TuxMachines: Raspberry Pi 101 – An Introduction to the Raspberry Pi GPIO

Wednesday 24th of January 2018 09:29:51 AM

An important feature of the Raspberry Pi is the row of GPIO pins, where GPIO stands for general purpose input/output. It will allow us to communicate between Pi and the outside world. We have 40pins on Pi, we count these pins from left to right out of which seventeen pins are GPIO pins. Different pins are used for the different functions and can be connected to a number of external peripherals such as buttons, lights, relays, sensors, etc.

TuxMachines: DLP platform for 3D vision teams up with Raspberry Pi

Wednesday 24th of January 2018 09:06:33 AM

Keynote Photonics has launched a $499 “LC3000G2-Pi” light-steering and 3D vision add-on for the Raspberry Pi, and will soon ship a “LC3000G2-PRO,” which similarly offers TI’s DLP3000 chipset, but runs TI Lightcrafter APIs on its own DM365-based Linux board.

Texas Instruments’ Linux-driven DLP (digital light processing) technology was originally launched as a projection technology, and is still primarily used for projection applications ranging from pico projectors you can plug into your laptop to advanced digital cinema projection machines. Yet, the technology is increasing moving into machine vision.

  • WebRender capture infrastructure

    For over a year now, I’ve been hacking on WebRender. It was born in Servo as an experimental way to batch the painting and compositing of the web content on GPU. Today it’s a solid piece of engineering that’s going to mainline Firefox as the next big Rust-written component within the Quantum project. You can read more about WebRender on our team’s blog as well as this wonderfully illustrated article by Lin Clark.

  • The Different Types of Privacy Protection

    Many of your favorite sites keep track of what you do online. They may do it to understand if you’re interested in a particular article, item or activity. They may do it to make your experience of their site easier. They may also track you so they can try to sell you things.

    Online ads can be customized on the fly based on what you do. Been searching for a new pair of Chucks? Mega Shoe Company has a great deal for you. To serve those custom ads at just the right time, the shoe company needs to know where you go online. Is that bad? Some argue that customized (targeted) ads are much better than traditional billboards or radio spots. At least with targeted ads, there’s a good chance you’ve been looking for what they’re selling. But you may not want companies following you around the web.

  • Introducing the MDN Product Advisory Board: actions and impressions from our first meeting

    On January 11th, 2018, Mozilla held the first in-person meeting of the MDN Product Advisory Board (PAB) in London. The goal of the MDN Product Advisory Board, in collaboration with Microsoft, Google, and other industry leaders, is to provide guidance that helps MDN be the best reference for web developers.

    To that end, I’m pleased to announce that the web platform consultancy Bocoup, represented by Rick Waldron, will be joining the MDN Product Advisory Board starting in February. Bocoup brings a practitioner’s perspective to the the standards process and participates in a wide range of open source projects. Rick has actively contributed to MDN since May of 2011, writing documentation, reviewing contributions, and participating in the maintenance of the JavaScript Reference sub-articles. He’s written proposals and specifications for new JavaScript APIs and syntax, participated in ECMAScript® 2015, 2016, 2017 Language Specifications, and represents Bocoup at ECMA TC39 meetings. I’m very excited Rick will be adding his considerable industry knowledge and JavaScript focus to the board and look forward to him joining our next meeting.

TuxMachines: Security Leftovers

Wednesday 24th of January 2018 05:31:45 AM
  • Security updates for Tuesday
  • Initial Retpoline Support Added To LLVM For Spectre v2 Mitigation

    The LLVM code has been merged to mainline for the Retpoline x86 mitigation technique for Spectre Variant 2. This will be back-ported to LLVM 6.0 and also LLVM 5.0 with an immediate point release expected to get this patched compiler out in the wild.

    The compiler-side work -- similar to GCC's Retpoline code -- is to avoid generating code where an indirect branch could have its prediction poisoned by a rogue actor. The Retpoline support uses indirect calls in a non-speculatable way.

  • Teen Hacker Who Social Engineered His Way Into Top-Level US Government Officials' Accounts Pleads Guilty To Ten Charges

    The teenage hacker who tore CIA director John Brennan a new AOL-hole is awaiting sentencing in the UK. Kane Gamble, the apparent founder of hacker collective Crackas With Attitude, was able to access classified documents Brennan has forwarded to his personal email account by posing as a Verizon tech. Social engineering is still the best hacking tool. It's something anyone anywhere can do. If you do it well, a whole host of supposedly-secured information can be had, thanks to multiple entities relying on the same personal identifiers to "verify" the social engineer they're talking to is the person who owns accounts they're granting access to.

    Despite claiming he was motivated by American injustices perpetrated around the world (Palestine is namechecked in the teen's multiple mini-manifestos), a lot of what Gamble participated in was plain, old fashioned harassment.

  • The Guardian view on cyberwar: an urgent problem [Ed: Lists several attacks by Microsoft Windows (but names neither)]

    The first known, and perhaps the most successful of these, was the joint US/Israeli Stuxnet attack on the Iranian nuclear programme in 2009. Since then there has been increasing evidence of attacks of this sort by Russia – against Estonia in 2009, and then against Ukraine, where tens of thousands of attacks on everything from power supplies to voting machines have opened an under-reported front in an under-reported war. Across the Baltic, the Swedish government has just announced a beefed-up programme of civil defence, of which the most substantial part will be an attempt to protect its software and networks from attacks. Meanwhile, North Korean state hackers are blamed by western intelligence services for the WannaCry ransomware attacks which last year shut down several NHS hospitals in the UK. Persistent reports suggest the US has interfered in this way with North Korea’s nuclear missile programme.

How To Make Good Use Of 'grep' Command

​Linux and UNIX systems come with a shell command known as ‘grep’. This simply looks for a specified text, or pattern, in a file or an entire directory. The most common usage is for quickly searching a file for occurrences of a pattern, which can be in plain text, or in the form of a regular expression. Here, the patterns used will be simple text rather than regular expressions. Read
