IPCC bibtex entries

I repeatedly stumbled over needing bibtex entries for the IPCC reports. So I guess, others might stumble over that, too. Here I share my bibtex entries for some parts of the IPCC reports.1

IPCC 1990 WG1 (physical science basis)

@BOOK{IPCC1990Science,
  title = {Climate Change 1990 The Science of Climate Change},
  publisher = {The Intergovernmental Panel on Climate Change},
  year = {1996},
  editor = {J.T. Houghton and G.J. Jenkins and J.J. Ephraums},
  author = {IPCC Working Group I}
}

  1. In IPCC 2013 WG1 they finally provide bibtex in their zip of references, but without item headers — you can’t use these directly. 

Freenet as backing store for sites on the clearnet (in use today)

Chris Double (bluishcoder) changed his main website to be served directly from Freenet:

Thanks to this, the same article is now available from my inproxy.

And, naturally, from Freenet:

Information challenges for scientific publishing

On 2015-08-27, Researchers from the Reproducibility Project: Psychology reported that in 100 reproduction studies, only “47% of original effect sizes were in the 95% confidence interval of the replication effect size” (RPP SCIENCE 2015, an overview of the results is available in Scientific American; in german from DLF Forschung Aktuell).

I take this worrying result as cue to describe current challenges to scientific publishing and measures to address them — including reproduction experiments, and what to do if they contest previously published and referenced work.

Scientific publishing has come a long way since its beginning, and its principles have allowed it to scale up from a few hundred active scientists worldwide to conferences with tens of thousands of people for a given topic. But in the last few years it hit its limits. It becomes harder each year to keep up with the amount of new papers being published and even scientists from similar fields repeatedly reinvent the same methods. To scale further and to continue to connect the scientific community, it must adapt to make it easier to get an understanding of the current state of science and keep up to date with new findings.

To grow from these challenges, scientific publishing needs to

Freenet Communication Primitives: Part 2, Service Discovery and Communication

Basic building blocks for communication in Freenet.

This is a guide to using Freenet as backend for communication solutions - suitable for anything from filesharing over chat up to decentrally hosted game content like level-data. It uses the Python interface to Freenet for its examples.

This guide consists of several installments: Part 1 is about exchanging data, Part 2 is about confidential communication and finding people and services without drowning in spam and Part 3 ties it all together by harnessing existing plugins which already include all the hard work which distinguishes a quick hack from a real-world system (this is currently a work in progress, implemented in babcom.py which provides real-world usable functionality).

Note: You need the current release of pyFreenet for the examples in this article (0.3.2). Get it from PyPI:

# with setuptools
easy_install --user --egg pyFreenet==0.4.0
# or pip
pip install --user --egg pyFreenet==0.4.0

This is part 2: Service Discovery and Communication. It shows how to find new people, build secure communication channels and create community forums. Back when I contributed to Gnutella, this was the holy grail of many p2p researchers (I still remember the service discovery papers). Here we’ll build it in 300 lines of Python.

Data (netCDF4)

Calculating the area of arbitrary regions on the Earth approximated as an ellipsoid. I needed this for conversion between the output of different models.

It’s calculated in Emacs Lisp, which showed me that for somewhat complex mathematical tasks Lisp syntax isn’t only unproblematic, but actually helps avoiding mistakes. And full unicode support is great for implementing algorithms with ω, λ and φ.

concise commit messages

Written in the discussion about a pull request for Freenet.

When I look up a commit, I’m not searching for prose. I’m searching for short snippets of information I need. If they are long-winded explanations, I am unlikely to even read them.

To understand this, please imagine coming back home, getting off the bike and taking 15 minutes to look at the most recent pull-request.

Secure communication with GnuPG and E-Mail

How E-Mail with GnuPG could hide when you talk, where you talk from and what you talk about.

or in technical terms:

E-Mail with perfect forward security, hidden subject and masked date using GnuPG and better frontends.

If you regularly read my articles, you’ll know that I’m a proponent of connecting over Freenet to regain confidential and pseudonymous communication.

Here I want to show how it would be possible to use E-Mail with GnuPG to get close to the confidentiality of Freenet friend-to-friend communication, because we have the tech (among the most heavily scrutinized and well-tested technology we use today) and we have the infrastructure. All it requires are more intelligent E-Mail clients. Better UI which makes the right thing easy.

Real Life Infocalypse

  1. This guide shows the convenient way of working which has a higher barrier of entry. It uses WoT Pseudonyms to allow you to insert repositories by Pseudonym and repository name. If you can cope with inserting by private key and sending pull-requests manually, you can use it without the WoT, too, which reduces the setup effort quite a bit. Just skip the setup of the Web of Trust and Freemail and plugins. You can then clone the life repo via hg clone freenet://USK@6~ZDYdvAgMoUfG6M5Kwi7SQqyS-gTcyFeaNN1Pf3FvY,OSOT4OEeg4xyYnwcGECZUX6~lnmYrZsz05Km7G7bvOQ,AQACAAE/life-repo.R1/4 life-repo. See hg fn-genkey and hg help infocalypse for details.

Strong Kerrigan

When you win Starcraft 2 Heart of the Swarm in brutal difficulty without losing Kerrigan even once, you get an ending with a truly strong Kerrigan.234

Clearly you are my greatest failure. Now at long last, you will die.

Again Mengsk activates the Xel'Naga artifact. As the lightning from the artifact tears at her flesh and cracks every part of her body, Kerrigan rasps an answer:


  1. The epub icon was created by the Oxygen Team (kde.org) and is licensed under the GNU LGPL

  2. This is what I’d have wished to see. 

  3. All characters in this story belong to Blizzard. I also published this story in the Starcraft forums

  4. The one thing I resent about Kerrigan in Starcraft 2 is that they made her weak.

    In SC1 Kerrigan embraced and ruled the swarm. She started as strong terran, never to let anyone talk down to her, never afraid to say what she wanted. Then she got infested, and she prevailed over the infestation, becoming the queen of blades, ruling the Zerg instead of being ruled by the Overmind.

    In the cutscenes of SC2 she’s a helpless wreck, ever reliant upon the help of others and exposed as a tool of the overmind to free the swarm from Amon.

    It feels as if someone wrote the story to deconstruct the legend of the queen of blades. The in-game story seems much better, though. 

power and deception

A religious leader is nothing more than a media-star who managed to convince people that the tale, in which he or she is special, is actually true.

Just like aristocrats managed to convince people that what their ancestors did gives them the right to control the lives of other people.

And like the rich convince people that money gives them the right to control a larger part of the world than others.

Freenet: The forgotten cryptopunk paradise

PDF

PDF (to print)

Org (source)

Text (for email)

A long time ago in a chatroom far away, select groups of crypto-anarchists gathered to discuss the death of privacy since the NSA could spy on all communications with ease. Among those who proposed technical solutions was a student going by the name sanity, and he published the widely regarded first paper on Freenet: A decentralized anonymous datastore which was meant to be a cryptopunk paradise: true censorship resistance, no central authority and long lifetime only for information which people were actually interested in.

Many years passed, two towers fell, the empire expanded its hunt for rebels all over the globe, and now, as the empire’s grip has become so horrid that even the most loyal servants of the emperors turn against them and expose their dark secrets to the masses, Freenet is still moving forward. Lost to the eye of the public, it shaped and reshaped itself - all the while maintaining its focus to provide true freedom of the press in the internet.

Staying sane with Emacs (when facing drudge work)

I have to sift through 6 really boring config files. To stay sane, I call in Emacs for support.

My task looks like this:

GnuPG/PGP signature, short explanation

»What is the .asc file?« This explanation is intended to be copied as-is into emails when someone asks about your signature.

The .asc file is a signature which can be used to verify that the email was really sent by me and wasn’t tampered with.[1] It can be verified with standard email security tools like Enigmail[2], Gpg4win[3] or MacGPG[4] - and others tools supporting OpenPGP[5].

Conveniently convert CamelCase to words_with_underscores using a small emacs hack

I currently cope with refactoring in an upstream project to which I maintain some changes which upstream does not merge. One nasty part is that the project converted from CamelCase for function names to words_with_underscores. And that created lots of merge errors.

Today I finally decided to speed up my work.

The first thing I needed was a function to convert a string in CamelCase to words_with_underscores.

Unicode-Characters for TODO-States in Emacs Orgmode

By default Emacs Orgmode uses uppercase words for todo keywords. But having tens of entries marked with TODO and DONE in my file looked horribly cluttered to me. So I searched for alternatives. After a few months of experimentation, I decided on the following scheme.

Let us talk over Freenet, so I can speak freely again

I sent this email to many of my friends to regain confidential private communication. If you want to do the same, feel free to reuse the text-version (be sure to replace the noderef textblock with your own noderef from http://127.0.0.1:8888/friends/myref.txt). This text is also available in Freenet.

About 10% of my friends joined - which is enough to build the darknet and makes it possible for me to speak freely again.

First: The Essence of this text:

I’ve been censoring my emails for years. Not just what I write, but also whom and when.

Freenet allows me to write invisible messages to my friends. Those are messages I do not need to censor. They give me freedom. Surveillance can show that we could write, but not whether, when or what we actually write. If Freenet is used for that, it needs very little resources.

This is how to connect:

  1. Download and install Freenet from https://freenetproject.org,
  2. in the automatically opened setup wizard select “only friends”
  3. Copy the textblock1 you got with my email and paste it into the textfield on http://127.0.0.1:8888/addfriend/
  4. Then just send me what Freenet shows on the page http://127.0.0.1:8888/friends/myref.txt (attach to an email or just copy it into the email)

As soon as I add you, too, we are connected. We can then write messages via the friends page (click my name):

  • Write message,: http://127.0.0.1:8888/friends/
  • Read messages: http://127.0.0.1:8888/alerts/

don’t change your habits - fix your tools!

→ In don't run 'strings' on untrusted files Michal Zalewski complained that running the strings-utility for computer forensics or other fields of information security could make you vulnerable yourself, so you should not use that. Given that strings is Free Software, I find a different conclusion from the vulnerability of tools used by professional forensics people.

I’d say if you’re actually using these tools to earn money, it is high time to go in and fix them.
