The goal of this book is to document commonly-known and lesser-known methods of doing various tasks using only built-in bash features. Using the snippets from this bible can help remove unneeded dependencies from scripts and in most cases make them faster. I came across these tips and discovered a few while developing neofetch, pxltrm and other smaller projects.
Labenz, das Ein allgemein bekannter Gegenstand oder eine vertraute Erfahrung, für den oder die bisher noch keine Bezeichnung existiert. Douglas Adams, John Lloyd & Sven Böttcher: Der tiefere Sinn des Labenz
Im Leben gibt es unzählige Dinge, Gefühle, Menschentypen und Situationen, die jeder aus dem Alltag kennt, denen man aber bisher versäumt hat, einen Namen zu geben. Wer kennt das nicht: Man steht gedankenverloren in der Küche und fragt sich, was man dort eigentlich wollte. Oder wie heißt eigentlich dieser halblose Plastikrand unten an Kunststoffflaschenschraubdeckeln?
Michelin Guides are a series of guide books published by the French tyre company Michelin for more than a century. The term normally refers to the annually published Michelin Red Guide, the oldest European hotel and restaurant reference guide, which awards up to three Michelin stars for excellence to a select few establishments.
A purchase of this guide is recommended in any case but these days people also need something they can intuitively use and which integrates into already existing workflows.
These people, like myself, need a map and maybe more details in a machine readable, filterable spreadsheet.
And as time goes on it might be quite useful to have all the sources that lead to these great tables and maps. Sources that allow you to crawl and grab these information.

Last week we were approached by Prof. Dr. Nicole Zillien from Justus-Liebig-University in Gießen/Germany. She explained to us that she currently is working on a book.
In this book an empirical analysis is carried out on “quantified-self” approaches to real life problems.
With the lot of information and data we had posted on our personal website(s) like this blog and the “loosing weight” webpage apparently we qualified for being mentioned. We were asked if it would be okay to be named in the book or if we wanted to be pseudonymized.
Since everything we have posted online and which is publicly accessible right now can and should be quoted we were happy to give a go-ahead. We’re publishing things because we want it to spur further thoughts.
It will be out at the end of 2019 / beginning of 2020. As soon as it is out we hope to have a review copy to talk about it in this blog once again.
We do not know what exactly is being written and linked to us – we might as well end up as the worst example of all time. But well, then there’s something to learn in that as well.
Since a couple of months we are trying harder to learn a foreign language.
And as we excepted it is very hard to get a proper grasp on speaking the language. Especially since it is a very different language to our mother tongue.
And while comfortably interacting with digital assistants around the house every day in english and german the thought came up: why don’t these digital assistants help with foreign language listening and speaking training?
I mean Google Assistant answers questions in the language you have asked them. Siri and Alexa need to know upfront in which language you are going to ask questions. But at least Alexa can translate between languages…
But with all seriousness: Why do we not already have the obvious killer feature delivered? Everyone could already have a personal language training partner…
Dicordianism is a paradigm based upon the book Principia Discordia, written by Greg Hill with Kerry Wendell Thornley in 1963, the two working under the pseudonyms Malaclypse the Younger and Omar Khayyam Ravenhurst.
According to its primary historian, Adam Gorightly, Discordianism was founded as a parody religion. Many outside observers still regard Discordianism as a parody religion, although some of its adherents may utilize it as a legitimate religion or as a metaphor for a governing philosophy.
The Principia Discordia, if read literally, encourages the worship of Eris, known in Latin as Discordia, the goddess of disorder, or archetypes and ideals associated with her. Depending on the version of Discordianism, Eris might be considered the goddess exclusively of disorder or the goddess of disorder and chaos.
Both views are supported by the Principia Discordia. The Principia Discordia holds three core principles: the Aneristic (order), the Eristic (disorder), and the notion that both are mere illusions.
Due to these principles, a Discordian believes there is no distinction between disorder and chaos, since the only difference between the two is that one refers to ‘order’.
This is likely a major reason for the inconsistency in the wording. An argument presented by the text is that it is only by rejecting these principles that you can truly perceive reality as it is, chaos.
So you’re listening to this audio book for a while now, it’s quite long but really thrilling. In fact it’s too long for you to go through in one sitting. So you pause it and eventually listen to it on multiple devices.
We’ve got SONOS in our house and we’re using it extensively. Nice thing, all that connected goodness. It’s just short of some smart features. Like remembering where you paused and resuming a long audio book at the exact position you stopped the last time. Everytime you would play a different title it would reset the play-position and not remember where you where.
With some simple steps the house will know the state of all players it has. Not only SONOS but maybe also your VCR or Mediacenter (later use-case coming up!).
Putting together the strings and you get this:
Whenever there’s a title being played longer than 10 minutes and it’s paused or stopped the smart house will remember who, where and what has been played and the position you’ve been at.
Whenever that person then is resuming playback the house will know where to seek to. It’ll resume playback, on any system that is supported at that exact position.
Makes listening to these things just so much easier.
Bonus points for a mobile app that does the same thing but just on your phone. Park the car, go into the house, audiobook will continue playback, just now in the house instead of the car. The data is there, why not make use of it?
The next time you stumble across a PDF file with security and not allowing you to print or copy/paste.
“QPDF is a command-line program that does structural, content-preserving transformations on PDF files. It could have been called something like pdf-to-pdf. It also provides many useful capabilities to developers of PDF-producing software or for people who just want to look at the innards of a PDF file to learn more about how they work.
QPDF is capable of creating linearized (also known as web-optimized) files and encrypted files. It is also capable of converting PDF files with object streams (also known as compressed objects) to files with no compressed objects or to generate object streams from files that don’t have them (or even those that already do). QPDF also supports a special mode designed to allow you to edit the content of PDF files in a text editor. For more details, please see the documentation links below.
QPDF includes support for merging and splitting PDFs through the ability to copy objects from one PDF file into another and to manipulate the list of pages in a PDF file. The QPDF library also makes it possible for you to create PDF files from scratch. In this mode, you are responsible for supplying all the contents of the file, while the QPDF library takes care off all the syntactical representation of the objects, creation of cross references tables and, if you use them, object streams, encryption, linearization, and other syntactic details.
QPDF is not a PDF content creation library, a PDF viewer, or a program capable of converting PDF into other formats. In particular, QPDF knows nothing about the semantics of PDF content streams. If you are looking for something that can do that, you should look elsewhere. However, once you have a valid PDF file, QPDF can be used to transform that file in ways perhaps your original PDF creation can’t handle. For example, programs generate simple PDF files but can’t password-protect them, web-optimize them, or perform other transformations of that type.”
The second edition of the book “Security Engineering” by Ross Anderson is available as a full download. It’s quite a reference and a must-read for anybody with an interest in security (which for example all developers should have).
“When I wrote the first edition, we put the chapters online free after four years and found that this boosted sales of the paper edition. People would find a useful chapter online and then buy the book to have it as a reference. Wiley and I agreed to do the same with the second edition, and now, four years after publication, I am putting all the chapters online for free. Enjoy them – and I hope you’ll buy the paper version to have as a conveient shelf reference.”
SPAUN or Semantic Pointer Architecture Unified Network is a promising next step in the pursuit to simulate a human brain. Built upon the Nengo Neural Simulator scientists at the University in Waterloo/Ontario were able to report on their first break-through results.
In 2013 there will be a book from Oxford University press called ‘How to build a brain’ which will describe in depth what made the astonishing results possible.
But what are the results?
Well that looks like number recognition. In fact that’s what it is. SPAUN – that’s how the scientists refer to their frankenstein-brain – is capable of solving 8 different tasks now. One of them is number recognition. There are videos of all 8 tasks being performed.
The Semantic Pointers are named after the pointers usually common in computer science:
“Higher-level cognitive functions in biological systems are made possible by semantic pointers. Semantic pointers are neural representations that carry partial semantic content and are composable into the representational structures necessary to support complex cognition.
The term ‘semantic pointer’ was chosen because the representations in the architecture are like ‘pointers’ in computer science (insofar as they can be ‘dereferenced’ to access large amounts of information which they do not directly carry). However, they are ‘semantic’ (unlike pointers in computer science) because these representations capture relations in a semantic vector space in virtue of their distances to one another, as typically envisaged by connectionists. “
Those who know me well know that I am a strong believer of artificial intelligence. We’re not there yet. Not even close, I don’t know if we (as in humanity) even left the launchpad. But I strongly believe that it will be possible to simulate human thoughts – maybe not in the way AI is defined:
“The field was founded on the claim that a central property of humans, intelligence—the sapience of Homo sapiens—can be so precisely described that it can be simulated by a machine.This raises philosophical issues about the nature of the mind and the ethics of creating artificial beings, issues which have been addressed by myth, fiction and philosophy since antiquity.Artificial intelligence has been the subject of optimism,but has also suffered setbacksand, today, has become an essential part of the technology industry, providing the heavy lifting for many of the most difficult problems in computer science.” (Wikipedia)
More on that in another article in the future since I started working on that subject earlier and now I come across a lot of authors and mostly science fiction books that deal with that topic.
Now there is a new book by Ray Kurzweil. It’s called “How To Create A Mind” and deals with the topic of how human thoughts come to be and how the human mind seems to work.
“Now, in his much-anticipated How to Create a Mind, he takes this exploration to the next step: reverse-engineering the brain to understand precisely how it works, then applying that knowledge to create vastly intelligent machines.
Drawing on the most recent neuroscience research, his own research and inventions in artificial intelligence, and compelling thought experiments, he describes his new theory of how the neocortex (the thinking part of the brain) works: as a self-organizing hierarchical system of pattern recognizers. Kurzweil shows how these insights will enable us to greatly extend the powers of our own mind and provides a roadmap for the creation of superintelligence—humankind’s most exciting next venture. We are now at the dawn of an era of radical possibilities in which merging with our technology will enable us to effectively address the world’s grand challenges.”
In November 1998 there was a book released about file system design taking the Be File System as the central example.
“This is the new guide to the design and implementation of file systems in general, and the Be File System (BFS) in particular. This book covers all topics related to file systems, going into considerable depth where traditional operating systems books often stop. Advanced topics are covered in detail such as journaling, attributes, indexing and query processing. Built from scratch as a modern 64 bit, journaled file system, BFS is the primary file system for the Be Operating System (BeOS), which was designed for high performance multimedia applications.
You do not have to be a kernel architect or file system engineer to use Practical File System Design. Neither do you have to be a BeOS developer or user. Only basic knowledge of C is required. If you have ever wondered about how file systems work, how to implement one, or want to learn more about the Be File System, this book is all you will need.”
If you’re interested in the matter I definitely recommend reading it – it’s available for free in PDF format and will help to understand what those file system patterns are all about – even in terms of things we still haven’t gotten from our ‘modern filesystems’ today.
History was one of my favourite classes at school – I liked it so much that I even wrote one of my final examinations at the A levels in history. I like to know how stuff happened and I like to know what people got from it.
Being a german there’s a lot of history in the last 100 years guiding the interest. You can imagine that the darkest parts of those 100 years are the first and the second world war. Thankfully my generation never had to suffer through such a terrifiying time.
So for the equally interested reader of this article I have good news. In times of the internet we get access to documents that were previously hard or expensive (or both) to get. Like the original documents of the so called Nuremberg Trial – the Trial of the Major War Criminals before the International Military Tribunal in Nuremberg.
“This book describes a holistic approach to develop complex software systems based on the WebComposition process model. It shows how to integrate soft- and hardware components in a cost efficient and effective way using Web technologies and the Semantic Web. The WebComposition Concurrency System, a formal language to predict system dependencies and conflicts, allows efficient planing and monitoring of the development and operation process of the overall system.”
I had the pleasure to work with Andreas on several occasions. One that I remember with the strongest feelings is a 2 1/2 day around-the-clock hack-a-thon at Microsoft Research. We got it working back then!
For the last 8 years I am constantly trying to get him interested and convinced to work on things directly or remotely connected to some of the stuff I do – but up until now luck wasn’t on my side. Maybe someday :-)
My sincere compliments on achieving his goal on this. Congratulations!
That’s great news for everyone interested in science and history. As it turns out Google and PopSci just made their entire 137-year archive available online… good times!
“We’ve partnered with Google to offer our entire 137-year archive for free browsing. Each issue appears just as it did at its original time of publication, complete with period advertisements. It’s an amazing resource that beautifully encapsulates our ongoing fascination with the future, and science and technology’s incredible potential to improve our lives. We hope you enjoy it as much as we do.”
Just in time for the launch of Windows 7 Microsoft Press offers a free eBook download. These 332 pages are there to give you the essential guidance regarding topics like Planning the Deployment, actually Deploying the Platform and additional Applications, Migration, Windows PE and a ton of stuff I did not mention here.
Es ist schon extrem erstaunlich was in einem vorgeht und welch erstauntes Gesicht man macht wenn man durch Zufall einmal ein Video von den Sprechern der “Drei Fragezeichen” findet.
Hand aufs Herz: Klingen die Stimmen so wie die Personen aussehen? Also ich komm immer wieder aus dem Staunen nicht heraus wenn ich die Stimmen höre und die Gesicher dazu sprechen sehe. Da muss doch ein Trick dabei sein!
Ach übrigends sind heute auch noch zwei neue Folgen der “drei Fragezeichen” erschienen…
There are more than 10 free eBooks available about Python:
… like “Dive into Python”:
“This is a fantastic book that is also available in print. It covers everything, from installing Python and the language’s syntax, right up to web services and unit testing. This is a good book to learn from, but it’s also excellent to use a reference. I frequently find myself visiting the site! If you only read one book on this list make it this one.”
“Virtualization for Dummies – Sun and AMD Special Edition is now available! Published by the same folks who create all the “Dummies” books – this special edition version showcases Sun and AMD virtualization offerings, how they work together, and how they can benefit businesses. Learn about the latest virtualization technologies with this brief and easy-to-read booklet.”
“Nach einer missglückten Intimrasur liegt die 18-jährige Helen auf der Inneren Abteilung von Maria Hilf. Sie wartet auf den Besuch ihrer geschiedenen Eltern, in der irren Hoffnung, die beiden könnten sich am Krankenbett der Tochter endlich versöhnen. Unterdessen nimmt sie jene Bereiche ihres Körpers unter die Lupe, die gewöhnlich als unmädchenhaft gelten, und lässt Krankenpfleger Robin die Stellen fotografieren, die sich ihrem neugierigen Blick entziehen. Nebenher pflegt sie ihre Sammlung von Avocadokernen, die ihr auch in sexueller Hinsicht wertvolle Dienste leisten. Selbst wenn Helens Besessenheit eine Notoperation nötig werden lässt – ihr ungestümer Witz und ihre Wahrhaftigkeit machen sie zu einer Sensation nicht nur auf der Station des Krankenhauses. Sie spricht aus, was andere nicht einmal zu denken wagen. »Feuchtgebiete« ist eine Exkursion zu den letzten Tabus der Gegenwart. Mutig, radikal und provokant rebelliert Charlotte Roches Roman gegen Hygienehysterie und die sterile Ästhetik der Frauenzeitschriften, gegen den standardisierten Umgang mit dem weiblichen Körper und seiner Sexualität – und erzählt dabei die wunderbar wilde Geschichte einer ebenso genusssüchtigen wie verletzlichen Heldin.”
“Ahead of the release of the 2007 Microsoft Office system, Microsoft Corporation has fre- quently referred to what it calls the “new world of work” – a business environment and econ- omy characterized by mobility; a worldwide network of customers, partners, and suppliers; new compliance and regulatory requirements; and a need for broad visibility into business processes and the information that supports and governs them. Together, factors such as these drive the need for organizations to integrate business applications, documents, and workflows and transform the content of documents into business information they can act on. These factors make plain the essential link between knowledge workers, business informa- tion, business processes, and software. This free 236-pages ebook focuses on a critical element of Office development – Microsoft Windows SharePoint Services and Microsoft Office SharePoint Server 2007, plat- forms that developers can use to create collaboration applications as well as applications and features that support business intelligence, workflow, data calculation, team workspaces, document life cycle management, content management, knowledge discovery, and project management.”

The iRex iLiad e-ink e-book reader is such a fantastic device, a friend of mine is willing to put the >600 euro down to get one. And if he reads this, he’ll be even more motivated to bite the bullet:
“From the factory, the Iliad only uses and maintains Internet connectivity for a very short time and for one specific purpose; to connect to the Rex site. Some enterprising device owners put a little hack together with a PDF file and some http for an address bar and they’re now surfing the web as long they like on the Iliad.”
“The “theory of reality” that I advance on this website and in the book “Imagining the Tenth Dimension” is not the one that is commonly accepted by today’s physicists. Anyone wanting to know more about the currently established thinking behind string theory and the tenth or eleventh dimension should refer to such excellent books as “Parallel Worlds” by Michio Kaku, “The Fabric of the Cosmos” by Brian Greene, or “Warped Passages” by Lisa Randall.
I invite you to think of this as an entertaining diversion that for some people will have a strong and thought-provoking connection to their impression of how the world really works. If you click on “The Forum”, you will be taken to a page that gives readers an opportunity to debate the concepts presented in the book and this website more fully. Enjoy!”
Michael Hart wrote in a newsletter: “As most of you are aware, it is 4 weeks until we complete our 35th year of Project Gutenberg history, and we have about 380 eBooks left to make it to 20,000.
This would be about 95 per week. . .we did 82 this week.
So it’s not such a Big Push as we did to get to 10,000, but a rather smaller push, which is why you haven’t heard me say an awfully lot about it. . .things are working out much a closer match to reaching 20,000 on our 35th anniversary than anyone, myself included, would likely have predicted.”
I was in Bamberg the second half of last week to help my girlfriends mom moving into the new apartment. And since she has so many books it would be a great eye-catcher to just “stick” some of them on the wall. This invisible bookshelf is in stores for 18 euros. Which is… quite expensive for a bended piece of metal… but it looks so great.
