WireGuard. Fast, modern, secure VPN tunnel

Imago voragine.net
• ,

WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPsec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform (Windows, macOS, BSD, iOS, Android) and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry.

OpenWrt Project

• , ,

The OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Designing Tools and Activities for Data Literacy Learners

Imago voragine.net
• , ,

Data-centric thinking is rapidly becoming vital to the waywe work, communicate and understand in the 21st century.This has led to a proliferation of tools for novices that helpthem operate on data to clean, process, aggregate, and vi-sualize it. Unfortunately, these tools have been designedto supportusersrather thanlearnersthat are trying todevelop strong data literacy. This paper outlines a basicdefinition of data literacy and uses it to analyze the toolsin this space. Based on this analysis, we propose a set ofpedagogical design principles to guide the development oftools and activities that help learners build data literacy.We outline a rationale for these tools to be stronglyfocused,wellguided, veryinviting, and highlyexpandable. Based onthese principles, we offer an example of a tool and accom-panying activity that we created. Reviewing the tool as acase study, we outline design decisions that align it withour pedagogy. Discussing the activity that we led in aca-demic classroom settings with undergraduate and graduatestudents, we show how the sketches students created whileusing the tool reflect their adeptness with key data literacyskills based on our definition. With these early results inmind, we suggest that to better support the growing num-ber of people learning to read and speak with data, tool de-signers and educators must design from the start with thesestrong pedagogical principles in mind.

Clubhouse: una app para experimentos sociales a medio camino entre la radio y la conversación

Imago voragine.net
• ,

Otra de las cuestiones llamativas hasta el momento en Clubhouse es que las conversaciones no se graban ni se archivan. Rescatando esta tendencia que iniciara hace un par de años Snapchat y que durante un tiempo siguió Instagram (hasta que se crearon los Destacados, donde se pueden guardar historias de Instagram a largo plazo) se recupera esta idea que de momento aumenta el halo de misticismo que existe sobre la aplicación y lo que en ella sucede.

…está marcada por el sesgo con respecto a quién puede usar la aplicación. Además del hecho de que no todo el mundo puede permitirse un Iphone la sensación es que en la app hay muchos consultores, emprendedores y comunicadores huérfanos de congresos, talleres o espacios donde poner en práctica sus artes oratorias.

First Timers Only. Friendly Open Source projects should reserve specific issues for newbies

Imago voragine.net

Contributing to open source for the first time can be scary and a little overwhelming. Perhaps you’re a Code Newbie or maybe you’ve been coding for a while but haven’t found a project you felt comfortable contributing to.

Kent C. Dodds proposed First Timers Only to get new people to make their first contribution. Scott Hanselman blogged about Bringing Kindness Back to Open Source, so it was obvious that we team up and promote these ideas and get more folks involved in open source.

Net Neutrality and Free Software: The Case of Router Freedom in Europe

Imago voragine.net
• , , , ,

Router Freedom is a net neutrality principle that Internet Access Providers (IAPs) must not the limit the users’ right to choose their own routers and modems to connect to the Internet protected in Europe since 2015. However, new rules on EU has created challenges router freedom, given that IAPs will be able to limit the right based on « objective technological necessity ». The talk will go through the historical aspects and future developments in Europe.

Net neutrality is the principle that Internet Access Providers (IAPs) must treat all Internet communications equally, and not discriminate or charge differently based on user, content, website, platform, application and type of access equipment. The FSFE has been involved with net neutrality advocacy in Europe since 2013, achieving positive results in Germany with a law securing end-users the right of free choice of routers and modems.

In the context of the reform of European telecommunications law, EU Member States must implement in their national jurisdiction the European Electronic Communications Code (Directive (EU) 2018/1972), which brings new rules on router freedom, allowing IAPs to limit the rights of users if they can determine an « objective technological necessity » for imposing their routers and modems on consumers.

The talk will go through the historical developments in the last two years in Europe to present an overview on the positions on the debate in regards to router freedom and the consequences for Free Software.

As a take away, the talk will propose the discussion around the main principles of net neutrality and freedom of terminal equipment within the EU legal framework.

Is Newpipe better than Youtube / Vanced?

Imago voragine.net
• , , ,

On my journey towards being googleless, there is one service that has no match: Youtube. This site has the biggest catalog of videos. But, as great as it is, it also represents one of the main ways for Google to get revenue, serve ads and collect data from it’s users, which is big problem for people like me, looking for a way to stop them from getting every bit they can about my life.

I need Youtube, that’s how I learn stuff, that’s where my teachers upload their homework videos. And in times like these, it’s honestly the primary way of entertainment I have.

When I discovered Youtube Vanced, I was really happy, I had a way to consume Youtube without ads and, recently, without Sponsors. And yes, that was pretty convenient for me, but I still needed an account linked to the app if I wanted access to my Subscriptions.

So yeah, I was still being watched by Google, and it was not until a week ago, that I decided to do the full switch, and I installed Newpipe

¿Qué es un mapa dasimétrico?

mapa dasimétrico y mapa coroplético

Hace poco hice un mapa de las desigualdades vía el uso de coropletas. Pero estos tipos de mapas suelen distorsionar la relación entre la verdadera geografía subyacente y la variable representada.

Se debe a que las divisiones administrativas no suelen coincidir con la realidad geográfica. Además, grandes areas aparentan tener un peso que no tienen. Para reflejar mejor la realidad se hace uso de distribuciones más realista de la población como puede ser el uso de suelo.

Con técnicas de Sistemas de Información Geográfica es posible redistribuir la variable de interés en función de una variable más realista a menor unidad espacial. En este caso usé el uso de suelo urbano con 100 m de resolución.

El Open Inmersion Thermal Circulator (OITC) es la versión libre, doméstica y reciclada de un dispositivo de cocina a baja temperatura. Un dispositivo realizado con elementos básicos o de fácil adquisición que permitirá a cualquiera con un poco de curiosidad crear su propia herramienta de cocina avanzada de nivel profesional. Un Immersion Thermal Circulator o ITC es, básicamente, un termostato que permite crear una temperatura constante, de entre 5º y 100º C para cocinar de forma similar a la del baño maría. Es muy preciso: la temperatura en el recipiente es homogénea gracias a las hélices que mueven el agua, lo que garantiza una cocción del alimento controlada. Esta técnica de cocinado combina la cocina al vacío (sous vide) y la baja temperatura. respetando al máximo la estructura natural de los alimentos, gracias en buena parte a la ausencia de oxidación del proceso y a que los alimentos se cocinan condimentados en sus propio jugo.

What’s the difference between OpenID and OAuth?

Imago voragine.net
• , ,

OpenID is about authentication (ie. proving who you are), OAuth is about authorisation (ie. to grant access to functionality/data/etc.. without having to deal with the original authentication).

OAuth could be used in external partner sites to allow access to protected data without them having to re-authenticate a user.

The blog post « OpenID versus OAuth from the user’s perspective » has a simple comparison of the two from the user’s perspective and « OAuth-OpenID: You’re Barking Up the Wrong Tree if you Think They’re the Same Thing » has more information about it.

Other comparisons out there are recommending Operating Systems that are long dead or no longer relevant. This is most likely because these « Top 10 Open Source Linux Firewall Software » lists are copied from year to year by non-technical users, without doing the actual comparison.

Some Operating Systems have been superseded or simply stopped being maintained and became irrelevant. You want to avoid such systems because of security reasons – these distros use outdated and have insecure Linux/BSD kernels which can potentially expose you to security exploits.

Building my ideal router for $50

I’ve managed to cobble together a device that is not only dirt cheap for what it does, but is extremely capable in its own right. If you have any interest in building your own home router, I’ll demonstrate here that doing so is not only feasible, but relatively easy to do and offers a huge amount of utility – from traffic shaping, to netflow monitoring, to dynamic DNS.

I built it using the espressobin, Arch Linux Arm, and Shorewall.

The 9 Best Secure Routers of 2021

Imago voragine.net
• , , , ,

The Linksys WRT3200ACM has Tri-Stream 160 technology that doubles bandwidth to help maintain speed better than most dual-band routers. Additional features such as MU-MIMO technology helps each device stay connected to the network at the fastest possible speed without interfering with the performance of other devices.

Linksys’ Smart Wi-Fi smartphone app also lets you manage and monitor your network from anywhere at any given time, but it’s the open-source aspect that really shines for security-focused router buyers, since you can easily use “packages” from trustworthy open source distributions such as OpenWRT or DD-WRT and establish a secure VPN, monitor and analyze network traffic or detect network intrusions instantaneously. Since the firmware packages are all open source, that also means that they’ve been extensively “peer-reviewed” by security experts, making them much more likely to be free of vulnerabilities that hackers can exploit.

The Top 5 Best DNS Servers for improving Online Privacy & Security

SPs (Internet Service Providers) generally offer DNS services to their customers, so when you don’t set up DNS servers on your computer or router, your DNS queries will run on your ISPs DNS servers. Using the default ISP DNS servers can result in certain problems while browsing the Internet:

Issues can happen with DNS requests themselves; most of the time they’re unencrypted and this leaves room for different types of DNS attacks.

Block Unwanted Advertisements with a Hosts File on Linux

I surf the web an awful lot, probably slightly more than your average 13 year old geek. I notice that a lot of sites load rather slowly mostly because your waiting on content from outside the specific domain. For example if you go to a website like thechive.com (one of my favorites) you will notice it takes quite a long time loading the ads. It would be nice if you could block advertisements… oh you can?

Although I mentioned thechive.com I spend most of my time on the net looking for information, not entertainment. These ads really hinder my search speed!

So here is a quick way you can block all the ads. Not only will your surfing be faster but you will also save some bandwidth.

First off I would like to thank the fine folks at http://winhelp2002.mvps.org/ for doing all the leg work and collecting all the data necessary for this to work.

Las descargas irregulares no son un problema. En realidad, nunca lo fueron. En su momento eran, simplemente, la evidencia de que la distribución existente no satisfacía la demanda, y que eran precisos nuevos canales que lo hiciesen. Las descargas de música no disminuyeron cerrando páginas de descarga ni persiguiendo a usuarios: disminuyeron cuando llegó Spotify. Las de películas, cuando llegó Netflix. Siempre habrá un porcentaje de usuarios que en ningún caso iban a pagar por un contenido, que intentarán obtenerlo gratis, y tecnológicamente, siempre tendrán posibilidad de hacerlo.

GitHub’s 2020 State of the Octoverse Report Highlights: Developers are Working More Hours but Turning to Open Source Projects for Creative Outlets

Imago voragine.net
• , ,

more than 56 million developers who created 60+ million new repositories this past year

GitHub recorded 35% more repositories created than last year and 7.5 hours faster pull request merge times in teams’ most productive and collaborative weeks.

GitHub tracked an increase in open source activity on weekends and holidays, at the same time that Enterprise developer activity dropped. Open source project creation is also up by 25% year over year since April 2020.

The data suggests that even when developers conclude their regular work, they are turning to open source projects for creative outlets. These projects often provide meaningful connections and community while the world is stuck at home.

GitHub reports that its community is becoming more diverse as those who identify as developers have decreased from 60% in 2016 to 54% in 2020. Profiles related to education are growing (up from 17% in 2016 to 23% in 2020), followed by users working in data. The platform is becoming more approachable for collaborators who do not come from a development background.
