NOTHING TO HIDE, a film about surveillance and you
Nothing to Hide (Oct. 2016), by Marc Meillassoux and Mihaela Gladovic, questions the growing, puzzling and passive public acceptance of massive corporate and governmental incursions into individual and group privacy and rights through the “I have nothing to hide” argument.
Public money Public code
Why is software created using taxpayers’ money not released as Free Software?
We want legislation requiring that publicly financed software developed for the public sector be made publicly available under a Free and Open Source Software licence. If it is public money, it should be public code as well.
Code paid by the people should be available to the people!
Alphabet, Google’s parent company, would provide services in response to data harvested
a plausible urban future based on cities acting as important sites for ‘data extractivism’ – the conversion of data harvested from individuals into artificial intelligence technologies, allowing companies such as Alphabet, Google’s parent company, to act as providers of sophisticated and comprehensive services. The cities themselves, the project insisted, would get a share of revenue from the data.
What’s Wrong With Open Source Telegram?
…the Telegram API allows you to work with their data only. In other words, it’s impossible to store your data on a separate server or a database. The API will let you create an app that interacts with the Telegram messaging app, but this app won’t be able to live a life of its own.

Construir un mundo rural vivo, igualitario e inclusivo
En lo rural se puede vivir bien porque la cercanía entre las personas, aunque trae algunas incomodidades y control sobre la gente, permite una corriente de solidaridad, ayuda mutua y compañía; Un hacer las cosas conjuntamente que, si es bien encauzada, permite un trabajo comunitario que posibilita un desarrollo participativo e ilusionante, en el que todas las personas en pie de igualdad puedan crecer y desarrollarse.
Las personas jóvenes necesitan de espacios propios que puedan servirles de escuela de autogestión, en toda la extensión de la palabra, desde su ocio, a su vida, su profesión y su desarrollo personal, con derecho a acceder en el medio en el que viven a las tecnologías y los recursos sociales y culturales en la misma medida que otros jóvenes de la ciudad.
Open Data Barcelona vs Google Sidewalk Labs
La Oficina [Open Data Barcelona], que es parte del Plan de Transformación Digital del Ayuntamiento que dirige la Comisionada de Tecnología e Innovación Digital, Francesca Bria, pretende el gobierno público de los datos en un trabajo en tres líneas: captación y almacenamiento, analítica y predicción, y comunicación y difusión. Es decir, el organismo captará información por sus propios medios y sensores pero también los pedirá a compañías que operan en el entorno urbano (telefónicas, energéticas y otras), los analizará y empleará para hacer con mejor tino sus políticas y los podrá a disposición de la ciudadanía, la universidad o quien los requiera.
Una oficina para “remunicipalizar la información” y convertir los datos en lo que son, un bien común.
[Sidewalk Labs] …el modelo urbanístico de Google no está tan lejos del de Blackstone (recuerdo: uno de los grandes imperios inmobiliarios del mundo) pero suma a éste la apropiación de la información, su gestión y su uso. Es decir, ya no sólo se trata de privatizar el espacio público, sino los datos que se generan en él (y en los espacios privados de cada familia y empresa que habite el barrio).
Curaengine Slicer. Support configuration options explained
Some models have overhanging parts, which means that parts of the model float mid-air when you would print the model. In this case, you must print a support structure under the model to prevent the plastic from falling down. This can be achieved by enabling generate support.

How do we take a feminist perspective on the design of visualizations? D’Ignazio cited six points that might bring us there
D’Ignazio says this issue is compounded by the fact that women and people of color are underrepresented in data science and technical fields in general, a trend that is worsening. She also highlights skewed quantity and quality of data that is collected about various groups of people. For instance, there are very detailed datasets on gross domestic product and prostate function, but very poor datasets on hate crimes and the composition breast milk.
¿Como se calcula el dinero que debemos pagar, por los servicios libres que usamos?
Darme cuenta que lo que me regalan las grandes coorporaciones no es tanto como les gusta hacernos creer, bajo su eslogan de gratis. Sacan mucho mas de mis datos que yo de sus servicios.
Acomodar mis practicas a mi discurso. Porque la soberanía tecnologica como los feminsismos no se basan solo en teorias si no NUESTRAS PRACTICAS.
Dejar de acumular servicios, como una depredarora capitalista. Y usar solo los que cuido y pago.
Repasar lo aprendido y usar la red optimizando recursos y no a lo capitalista ( consumista, acumuladora) solo porque es gratis.

Securely backing up your files with rdiff-backup and sudo
A guide on setting up rdiff-backup and using sudo to run rdiff-backup without running it as the root user.
rdiff-backup – A Remote Incremental Backup Tool for Linux
Significantly, it preserves subdirectories, dev files, hard links, and critical file attributes such as permissions, uid/gid ownership, modification times, extended attributes, acls, and resource forks. It can work in a bandwidth-efficient mode over a pipe, in a similar way as the popular rsync backup tool.
rdiff-backup backs up a single directory to another over a network using SSH, implying that the data transfer is encrypted thus secure. The target directory (on the remote system) ends up an exact copy of the source directory, however extra reverse diffs are stored in a special subdirectory in the target directory, making it possible to recover files lost some time ago.
How to fix all of your crontab related woes/problems (Linux)
Every user on a system may have their own crontab file. The location of the root and user crontab files are system dependant but they are generally below /var/spool/cron.
There is a system-wide /etc/crontab file, the /etc/cron.d directory may contain crontab fragments which are also read and actioned by cron. Some Linux distributions (eg, Red Hat) also have /etc/cron.{hourly,daily,weekly,monthly} which are directories, scripts inside which will be executed every hour/day/week/month, with root privilege.
How can I own an IP address?
IP Addresses are purchased in blocks by companies with a hell of a lot of money and more importantly, infrastructure. When you get one, unless you are going direct to your RIR (Regional Internet Registry), you are only renting the IP.
Changing default crontab editor
Just simply run select-editor, this will let you choose any editor you want.

Search and replace or delete multiples lines in vim
The :global command is your friend – learn it well. It lets you run arbitrary :ex commands on every line that matches a regex. It abbreviates to :g.
To delete all lines that match “George Bush”:
:g/George Bush/ d
The command that follows can have its own address/range prefix, which will be relative to the matched line. So to delete the 5th line after George Bush:
:g/George Bush/ .+5 d
To delete the DEBUG log entries:
:g/DEBUG/ .,+10 d

Amsterdam reduce de 60 a 30 días el permiso para alquilar pisos en Airbnb
Los pisos en plataformas de alojamiento vacacional aumentaron de 4.500 en 2013 a 22.000 en 2017.
El problema de la vivienda en la capital holandesa, cuyos alquileres son los más altos de todo el país, llevó a un Tribunal de distrito a dictaminar recientemente que una persona puede perder su casa en Amsterdam si su propietario la usa exclusivamente para alquiler vacacional y, por esa razón, no reside en ella.
How Dokuwiki loads Javascript and how to add custom JS code
All JavaScript is collected and delivered by lib/exe/js.php. This file will concatenate all found files, whitespace compress (if compress is enabled) and cache the result. It also instructs browsers to cache the file, so when you are developing new JavaScript, be sure to refresh your browser cache (hitting Shift-F5, Shift+CTRL+R or similar) whenever your script was updated.
DokuWiki will load JavaScript from the following places:
autogenerated JavaScript (language strings, config settings, toolbar)
lib/scripts/*.js
lib/plugins/*/script.js
lib/tpl/
conf/userscript.js
Las colmenas de abejas de la miel ni son naturales ni ayudan al medioambiente

Advanced Deanonymization through Strava: how would I go for someone else’s strava secrets?
Here are some things Strava may reveal
Whether you run, swim, ski or cycle.
If you tell it, what bicycles you have.
Who you go out on a run or ride with
When you are away from your house
Where you commute to, and when
Your fitness, and whether it is getting better or worse.
When you travel, what TZ, etc.
The fact that you can infer nation-state secrets is an interesting escalation. Currently it’s the heatmap which is getting the bad press, which is part of the dataset that Strava offer commercially to councils. FWIW, the selection bias on Strava data (male roadies or mountain bikers) means that its not that good. If someone bought our local data, they’d infer that muddy wood trails with trees and rocks are what the city needs. Which is true, but it doesn’t address the lack of any safe way to cross the city.
What is interesting about the heat map, and not picked up on yet, is that you can potentially deanonymize people from it.
Internet metaphors
social metaphors tend to communicate more about the values of society rather than the technology of the Internet itself
The electronic frontier metaphor conceptualizes the Internet as a vast unexplored territory, a source of new resources, and a place to forge new social and business connections.
