3D Printing (video)

In my 'series' about the Maker movement, I wrote about the new makers and Fab Labs. I also mentioned some resources. At the moment I'm reviewing Makers by Chris Anderson. As this article isn't ready yet, I post a quick but interesting video by PBS Off Book.

Enjoy!

Maker movement (resources)

In my series about Makers, I wrote about the new makers and Fab Labs. For those interested, I gathered some links for further reading. Do you know other useful resources? Please mention them in the comments or drop me a line.

Enjoy!


3D Printing refers to any of the various processes for printing a three-dimensional object.

CAD is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design.

CAM is the use of computer software to control machine tools and related machinery in the manufacturing of workpieces.

CNC Machines. Numerical control (NC) is the automation of machine tools that are operated by precisely programmed commands encoded on a storage medium, as opposed to controlled manually via hand wheels or levers, or mechanically automated via cams alone.

MIT's Center for Bits and Atoms is an interdisciplinary initiative exploring the boundary between computer science and physical science.


Fab Lab is a technical prototyping platform for innovation and invention, providing stimulus for local entrepreneurship. A Fab Lab is also a platform for learning and innovation: a place to play, to create, to learn, to mentor, to invent.

Instructables is a place that lets you explore, document, and share your creations.

Local Motors. We combine co-creation and micro-manufacturing to bring hardware innovations to market at unprecedented speed.

MAKE magazine brings the do-it-yourself mindset to all the exciting projects in your life and helps you make the most of technology at home and away from home.

Maker Faire is a family friendly event celebrating technology, education, science, arts, crafts, engineering, food, sustainability, and more. 

Maker Movement. Community enabled by a rekindled interest in manufacturing and hardware, accompanied by the proliferation of inexpensive or less expensive distributed, democratizing manufacturing tools.

The Maker Movement Manifesto: Rules for Innovation in the New World of Crafters, Hackers, and Tinkerers

Maker Stuff supplies the most innovative equipments which turn your ideas into your product. 


Popular Mechanics helps people build, fix and customize the technology in their lives, from houses to hot rods to gaming systems.

Prosumer is a portmanteau originally formed by contracting producer with the word consumer.

Thingiverse is a thriving design community for discovering, making, and sharing 3D printable things. As the world's largest 3D printing community, we believe that everyone should be encouraged to create and remix 3D things, no matter their technical expertise or previous experience.

Unleash your creativity in a Fab Lab (video)

Last week, I wrote about the new makers. Neil Gerschenfeld was one of the people in the documentary.

This professor of the MIT Center for bits and atoms founded the Fab Labs. According to its website a...
"Fab Lab is the educational outreach component of MIT’s Center for Bits and Atoms (CBA), an extension of its research into digital fabrication and computation.
A Fab Lab is a technical prototyping platform for innovation and invention, providing stimulus for local entrepreneurship.
A Fab Lab is also a platform for learning and innovation: a place to play, to create, to learn, to mentor, to invent.
To be a Fab Lab means connecting to a global community of learners, educators, technologists, researchers, makers and innovators- -a knowledge sharing network that spans 30 countries and 24 time zones.
Because all Fab Labs share common tools and processes, the program is building a global network, a distributed laboratory for research and invention."
To spread his ideas, he wrote Fab: The Coming Revolution on Your Desktop--from Personal Computers to Personal Fabrication and held an interesting TED Talk. Altough it was recorded in 2006, it's still fascinating.

Enjoy!

The new makers

It's been silent on my blog. For too long in fact. But hey, I've also other things to do! Now summer is over - at least here - I'm able to write again. Today, about the Maker Movement.

As I told earlier, we've a nice initiative in The Netherlands which is called Permanent Beta (as the site is in Dutch, you may translate it). The initiators may be inspired by the authors of The Start-up of You who encourage us - surprise, surprise - to live in permanent beta.

Among other activities, we follow a Dutch series of documentaries ('Tegenlicht') and discuss them during our MeetUPs. A few weeks ago, we started with The new makers.

After a short welcome, we watched the documentary. Among others prof. Neil Gerschenfeld of the MIT Center for bits and atoms told about his experiences at university. Jeremy Rifkin, consultant and author of The Zero Marginal Cost Society, gave his opinion on the development of producing at near zero marginal costs.

Afterwards, three people gave their opinion about the growth of the maker movement. We had good discussions, told each other about new developments and socialized.

Well, that's a brief summary, isn't it? For those interested, pictures, reports and even videos (in Dutch) of the event can be found on Permanent Beta and MeetUP.

I got interested in the topic. I think I'll start reading Makers and/or Fab. Next week more about Fab Labs. Are you already a prosumer? Do you use a 3D printer for example?

Enjoy!

Open Library

Today we'll talk about the Open Library. In fact. I will write and you may read it. ;-)

This library is an initiative of the Internet Archive. Its aim is to create a (web) page for every book which is quite ambitious. By creating such a huge database readers and book lovers are able to retrieve information about many published works.

But that's not all. It's also possible to read books as long as they are digitized. Registered users are allowed to read classics online or even download them. These are books published till 1922. They are avalaible in several formats like TXT, PDF and EPUB. At the moment of writing, over 1.000.000 titles are available for free.

Modern books are published as of 1923 and can be borrowed. Borrowed? Yes, registered users can check a book out for up to fourteen days. During that period, the lender is able to read it on- or offline. For the latter Adobe Digital Editions software is necessary. These are available for Windows and Mac; unfortunately there's still no Linux version. Users may loan up to five books a time all for free!

Are you already a member of the Open Library?

Keep on reading!

Windows XP alternatives

You may have noticed, Microsoft ends its support on Windows XP next week. What does that mean? Does it stop functioning? No, it will still work. However, Microsoft won't fix any bugs anymore. They won't fix security leaks either. And they don't update their virus scanner for XP any longer.

Is it possible to keep using XP? Yes it is possbile. However, it's not recommended. If you stay on XP, please install a decent virus scanner and a firewall. Furthermore, use a modern web browser. In stead of the Internet Explorer, start using Firefox, Chromium or Opera.

You'd better install another operating system to replace XP or alongside it. But which one? Windows 8 requires much more processing power. Your current computer won't be able to run it smoothly. But there are alternatives. I recommend Xubuntu, a Linux distribution ('distro') with a lightweight graphical user interface. So it is stable and fast. And best of all, it's free (as in 'freedom').

Before installing, you may test the live CD. Just put the CD (or DVD) in you computer and restart it. Now you can play with Xubuntu without changing anything to your current configuration. If you're satisfied, you may install it.

Installing is easy: just follow the wizard. Xubuntu comes with decent software like LibreOffice, Firefox, Thunderbird and more. Installing new applications is easy using the Software Center: just select and install. This operating system is user friendly. If you're still a bit uneasy: there's a very helpful online community.

For those interested, there's a whole bunch of other Linux distro's. For instance Linux Mint XFCE which is also a good choice. Many people love its polished looks. Another good one is Debian XFCE as it is very stable and fast. (XFCE is the graphical user interface used in all distro's mentioned above.)

Which OS are you going to use?

Enjoy!

Keepod

Recently, I wrote about portable Operating Systems. I found out, I'm not the only one. ;-) The people of Keepod created a complete Operating System on an USB stick. By seperating the software from the hardware, Keepod offers a simple and cheap solution for personal computing. Nice isn't it? But, do we need it?

As the costs of this way of computing is very low, it comes in reach for the poor. According to Keepod, 5 billion people don't have access to personal computing, let alone the internet. People don't need to possess a computer themselves any longer. Access to (a shared) one is enough. As the system requirements are low, old and refurbished computers will do.

Keepod contains Linux which is stable, 'light weight' and free (as in 'freedom'). Users are able to use the enclosed software. However, they may be able to install their own applications. All data are stored on the thumb drive, so they carry their data and don't leave traces on the guest PC's.

The costs of such a USB stick are only $ 7 (!). The Keepod project is in search for funding at Indiegogo. This isn't the first idea to bring computing to developing countries. An earlier initiative was One Laptop Per Child. As the name states, it's aim is to provide every child with a laptop for education purposes. Therefore they developed a rugged, low-cost, low-power, connected laptop. Many of them are sold and distributed.

Good initiatives! Do you know other projects like these?

Portable OS

Picture:

Last time, I wrote about portable software. I use these sort of applications daily on 'my' worklaptop and/or on desktop PC of customers. All these machines are equiped with Windows. But let's take it a step further: carry your entire Operation System (OS) along with your applications with you!

There are several ways to do so. Most Linux distro's provide a Live CD or DVD. Boot your computer from the CD/DVD and you'll experience a complete Linux system. However, it's not possible to save changes inside it's configuration. Also, data can't be saved ín the system. Of course, one save data to other drives, like hard discs or USB sticks.

Live CD/DVD's are useful to test new distro's or new releases of them. They can also be used as install media. Furthermore, they are useful to investigate a broken computer.

A second option to create a portable OS, is to install it to an USB stick. On Pendrive Linux you'll find instructions and software to create thumb drive of choice.

Last but not least, my portable distro of choice. I like Puppy Linux very much. It's a small Linux system with 'light weight' applications. The image file is about 200 MB. As it is a portable OS, it runs from the RAM of it's guest computer. I use it on my netbook with 1 GB RAM. On this configuration, Puppy is rather fast. For minimalists there are some other tiny distro's.

Do you carry a portable OS?

Enjoy!

Four principles for the open world (video)

At the moment, I'm reading Macrowikinomics: Rebooting Business and the World  written by Don Tapscott. In fact, I'm listening the audio book during my commute to work. My interest in his idea's grew during 'reading' the chapters.

After a while, I found out Tapscott spoke at TED some time ago. In Edingburgh he talked about openness. He explained the four principles of this concept:
  • Collaboration
  • Transparancy
  • Sharing
  • Empowerment



Along his speech, Tapscott wrote  Radical Openness: Four Unexpected Principles for Success .

Cyanogenmod

Last week, I told you what I use. Altough I like my good old Nokia, I also use a smartphone A not so new Samsung Galaxy Ace. As I don't like its Android flavour, I went looking for alternatives. I found out, it's possible to root a phone and install another flavour of Android, a so called ROM. Why? There are many reasons, like enhancing privacy, security and battery life. For me, it's first of all about freedom. That's why I like open source software.

I searched the web and found plenty alternatives. Cyanogenmod seemed to be the best. So I read their site, some reviews and downloaded the stable version for my device. Installation was painless. The result? The phone looks clean, offers many options and is easy to understand. Good work guys!

Now, I'm looking for useful apps. I found some examples here and there. I installed Brightness Level and QR Droid immediately. I also like the LinkedIn app.

I'm curious about my 'new' phone. Will I like it in the long term? Will it perform? Will its battery live longer (now it'll last only one day per charge)?

What's your OS of choice? Which apps do you like?

LyX - The document processor

Both at work and at home, I write and edit many documents. Personally, I prefer LyX as my writing tool altough I also use LibreOffice (at home) and the Office suite from Redmond (at Ordina).

Why using an exotic word processor? Well, because it separates text from lay out. While typing, one can concentrate on the text, without any hassle about font types and size, formats of numbering and bullets, headers and so on. The layout is defined in a template.

LyX - main screen (picture: LyX)

Dedoimedo wrote some interesting and useful articles about this document processor. First of all, he argues the way documents are meant to be written. He explains how to install LyX and how to get started. Furthermore, he gives us some tips and tricks and even more useful tricks. He even learns us how to convert documents to e-books.

Preview document (picture: LyX)

LyX is easy to install and easy to use. It's available for Linux, Mac, Windows, OS/2 and Haiku. I like distractless 'writing', creating professional looking documents. And best of all? As LyX is open source software, it's free (as in freedom). By combining it with the right keyboard layout and even a mechanical keyboard, you create a very productive writing tool.
What's your favorite document processor?

Happy writing!

Project Gutenberg

Are you looking for free e-books? Visit Project Gutenberg and you'll find plenty of them. At the time of writing, 42,000. Around 50 e-books are added weekly.

Long before Google started scanning books, Michael Hart  created an electronic text of the US Declaration of Independence by typing it into a computer. He did so in 1971. The US Bill of Rights and the Bible followed. A project was born. It was named after Johannes Gutenberg who introduced printing to Europe.

Hart's aim was to make e-texts and e-books available on every sort of computer. Therefore he started in ASCII. Later other standards were added like PDF, HTML and EPUB. In the early years, texts were typed by volunteers. Nowadays, the books are scanned and pre-read.

The books are free - as in freedom - as US copywrights are expired. The project is still looking  for volunteers and donations.

I really like this huge collection of books altough most of them are elder titles. The side is plain and simple.

Happy reading!

Open source software (video)

Recently, I wrote about The cathedral & the bazaar. A book about open source software. Why would people design and develop software in their spare free time and give it away for free? The RSA made a nice video about this topic in which they explain what motivates people.


This movie is based on the book Drive by Daniël Pink.

The cathedral & the bazaar (book review)

The Cathedral & the Bazaar: Musings on Linux and Open Source by an Accidental Revolutionary
Eric S. Raymond
Feedbooks, 2000

Open source software is increasingly popular these days. As I got interested in this phenomen, I decided to read some books about this topic. In this post, I'll review The Cathedral & the Bazaar by Eric Raymond.

The author (co-) developed Unix and open source software since the early 1980's. In the Unix tradition, these applications were small and single purposed. Till Linux was released, he believed there was a certain complexity above which a more centralized, a priori approach was required. It needed to be built like cathedrals, carefully crafted by individual wizards or small bands of mages working in splendid isolation. However, he found out the Linux community works different, despite its complex product. It releases software early and often. Its founder, Linus Torvalds delegates everything he can and he's open to the point of promiscuity. It seemed to resemble a great babbling bazaar of differing agendas and approaches out of which a coherent and stable system could seemingly emerge only by a succession of miracles. And it works!

How could this be possible? Raymond found out by doing. He met a problem with his e-mail client and started working on a piece of software called popclient which later became fetchmail. As internet access became cheap, it was easy to reach contributants all over the country and even abroad.

Many open source projects, are initiated by a problem of a software developer. He (or she) starts engineering and releases an early version through the web. Others - many call themselves hackers - get interested and start testing and co-developing. If the code isn't good enough, they throw it away and start again. The result is often good and simple software.

From a social point of view, a community initator attracks people e.g. with a nice puzzle. He interests them by discussing and designing possible solutions. During the project, he keeps them happy by rewarding them. These rewards can be honouring their ideas or code, features added or removed (!), etc. It's not about money. An attitude of egoless programming is needed. There are no territories and collegial reviews are strongly encouraged.

The author mentions some differences according to the development of proprietary software. First of all the open source community doesn't meet strict deadlines. Furthermore there's almost no budget. Lastly he discusses the role of project managers in traditional development. It's their job to claim and defend resources, to motivate project members and to keep an eye on the progress and scope of the project. Good project managers, like a friend of Eric, are busy with these tasks. However, in open source projects these are obsolete as people contribute voluntary.

In The cathedral & the bazaar, Raymond explains how open source software is created. He became aware of the way Torvalds and the Linux community developed their operating system. He took over their way of working. He guides his readers through the process of (re-) engineering an application explaining the lessons he learned. The book is not technical in a sense of detailling software code and so on. Therefore, it's readable for a broad adience. According to the open source principles, the book is available for free. There's also a short video of the book.

For me, the book was interesting to read. I learned a lot but there's one question left. What about developing open source software not initiated by a problem of a software engineer? E.g. for business applications. Or what about open source development at companies like Canonical, IBM, Oracle and RedHat? What are their drivers to create useable and reliable applications?

Happy reading!
