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.

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.

What is OLinuXino?

OLinuXino are series of powerful Linux-enabled Open Source Software and Open Source Hardware Open Source Hardware boards, designed and manufactured by Olimex LTD. Boards from the OLinuXino family can be manufactured with components suitable for operation in either industrial grade (-40+85)C or commercial grade (0-70)C temerpature range. Different OLinuXino boards use processors from different manufacturers – Allwinner, Freescale, etc.

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.

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

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.

ActivityWatch is an app that automatically tracks how you spend time on your devices.

It is open source, privacy-first, cross-platform, and a great alternative to services like RescueTime, ManicTime, and WakaTime.

It can be used to keep track of your productivity, time spent on different projects, bad screen habits, or just to understand how you spend your time.

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.

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.

¿Qué medidas tomas al navegar por internet?. ¿Te proteges contra scripts como javascript y otros, contra la publicidad, el rastreo y el fingerprinting o evitar en lo posible tu huella digital?. ¿Qué navegadores usas en tu ordenador?, ¿usas extensiones en los mismos?

Desde hace años uso Firefox compilado con unos cuantos arreglos. No suelo bloquear demasiado mediante extensiones y sí mediante firewall y el famoso /etc/hosts con miles de dominios y subdominios.

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 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.

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.

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.

I’m still early on my journey in front of a camera, but I wanted to share some tricks I’m using to come across more ‘naturally’, particularly the use of expanded awareness. These are: – to remain aware of the room while talking to the lens – to notice and avoid a natural ‘compression’ of space between myself and the lens – to continuously bring to mind the idea that there is a human that I’m in dialogue with

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.

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.

In my opinion, “instant, public, global messaging and conversation” should, in fact, be global. Distributed between independent organizations and actors who can self-govern. A public utility, without incentives to exploit the conversations for profit. A public utility, to outsurvive all the burn-rate-limited throwaway social networks. This is what motivated me to create Mastodon.

Besides, Twitter is still approaching the issue from the wrong end. It’s fashionable to use machine learning for everything in Sillicon Valley, and so Twitter is going to be doing sentiment analysis and whatnot when in reality… You just need human moderators. Someone users can talk to, who can understand context. Unscalable for Twitter, where millions of people are huddled together under one rule, but natural for Mastodon, where servers are small and have their own admins.

the telecom operator locates the damaged area by zeroing in on the problematic part. To do this, they send signal pulses through the cable from one end or base station. The damaged area (break) will bounce back the pulse to the signalling site which sent the data. Calculating the time delay from the reflected signal, engineers can zero in on the exact point and area of the problem. Then they send out a large cable repair ship, with fresh optic cables to replace the defective part under the sea. The cable is then lifted from the sea bed using special hooks (grapnel) and dragged onto the ship. The faulty cables are then spliced onboard, joined with a fresh cable, sealed with a watertight and anticorrosive covering and returned back to the seabed. Then the ship sends out the information to the base stations to test the cable again. Once the test signals are reaching the destination, the work is confirmed and the cable is repaired successfully. The data is then switched on and the connection restored. The entire process can take up to 16 hours or more, depending the number of cable breaks, successful repairs, time of day, weather conditions at sea and ships around the area.

Climate disaster could take away both their connection and a crucial source of income. And, ironically enough, these cables are used to help gather data on climate impacts, so climate change could mess up the very tools we need to monitor the impact of climate change.

The thing about buttons, though, is there seems to be some invisible magic taking place between the moment you press them down and when you get the expected result. You can never really be sure you caused the soft drink to appear without opening up the vending machine to see how it works.

Maybe there’s a man inside who pulls out the can of soda and puts it in the chute. Maybe there’s a camera watching the machine, and someone in a distant control room tells the machine to dispense your pop.

You just don’t know, and that’s how conditioning works. As long as you get the result you were looking for after you press the button, it doesn’t matter. You will be more likely to press the button in the future (or less likely to stop).

The problem here is that some buttons in modern life don’t actually do anything at all. The magic between the button press and the result you want is all in your head. You never catch on – because you are not so smart.

New Yorkers (those who don’t jaywalk, that is) have for years dutifully followed the instructions on the metal signs affixed to crosswalk poles:

To Cross Street

Push Button

Wait for Walk Signal

But as The New York Times reported in 2004, the city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals. More than 2,500 of the 3,250 walk buttons that were in place at the time existed as mechanical placebos. Today there are 120 working signals, the city said.

About 500 were removed during major construction projects. But it was estimated that it would cost $1 million to dismantle the nonfunctioning mechanisms, so city officials decided to keep them in place.

Most of the buttons were scattered throughout the city, mainly outside of Manhattan. They were relics of the 1970s, before computers began choreographing traffic signal patterns on major arteries.

La razón de esto la explicaron hace un tiempo en medios como el New York Times o Science Alert. Una ley estadounidense llamada ‘Americans With Disabilities Act’ y aprobada en 1990 que buscaba proteger a las personas con discapacidades físicas de situaciones como la de no poder entrar en un ascensor a tiempo antes del cierre de puertas. De repente, por ley, ya no se podían cerrar las puertas voluntariamente si ello implicaba cerrar el paso a alguien que usase una silla de ruedas o unas muletas.

Sin embargo, al mismo tiempo, quedó patente que botones como el de cerrar las puertas de un ascensor dan cierta sensación de control de una situación aunque a nivel efectivo no hagan nada. Esa sensación de control reduce el estrés y la ansiedad, según la profesora Ellen J. Langer de la Universidad de Harvard.

Así que a partir de 1990, todos los ascensores empezaron a fabricarse con botones de cerrar puertas que no hacían nada.

Captura de pantalla de switching.software

switching.software is a grassroots website, that is trying to let people know about ethical and easy-to-use alternatives to well-known websites, apps and other software.

Switching.software is a fork of a former website known as ‘switching.social’. It was created and maintained by an anonymous person and gained popularity in 2018 and 2019 – especially on the Fediverse.

Electronic Frontier Foundation co-founder John Gilmore said that the internet routed around censorship. But what if the net stopped being one big, connected thing? National governments are busy walling off their own sections, and in some cases changing the technologies that underpin it. What’s more, they’re not stopping at their own borders.

There are terms for this sliced-up internet, with rules that vary between countries. Some call it digital balkanisation. Others, like Julie Owono, call it the splinternet.

This set of digital gated communities is growing. Russia has the Runet, its domestic internet infrastructure, which it has been working to make independent from the external internet since at least 2014. The country unplugged the Runet from the rest of the world a year ago in a test run to see how it would fare on its own.

Still, national calls to wall off portions of the internet are spreading. In 2013, then-Brazilian president Dilma Rouseff called on countries in the UN to build their own sovereign internet government structures. North Korea has Kwangmyong, a centrally administered network accessible only via a heavily monitored Linux distro called Red Star. Cuba has RedCubana, an alternative to the open net that houses Cuban versions of popular websites like Wikipedia, along with local apps. Iran has its National Information Network (aka the Halal internet), a government-controlled network that hosts Iranian sites and tracks all its users. It allows heavily moderated access to the outside world.

The battleground of this splinternet, and where we really see what’s at stake, is the African continent, where billions are yet to be connected.

China has invested just over $300bn in Africa in the last two decades. In 2018 President Xi Jinping pledged $60bn in assistance, investment, and loans, $10bn of which will come from Chinese companies investing in the region.

Chinese companies have been busy helping countries in Africa roll out everything from fibre networks to smart city initiatives and data centres, as the Australian Strategic Policy Institute has documented.

Pop Shell is a keyboard-driven layer for GNOME Shell which allows for quick and sensible navigation and management of windows. The core feature of Pop Shell is the addition of advanced tiling window management — a feature that has been highly-sought within our community. For many — ourselves included — i3wm has become the leading competitor to the GNOME desktop.

Openbox is a stacking window manager, but there is a simple shell script called winfuncs, which can be used to tile the openbox stacked windows at any time. Winfuncs is based on wmctrl, an old command line tool that provides access for doing many neat things to many modern Linux window managers. This is almost as good as having a tiling manager; it only fails in that new windows opened after a tile has been completed will not be automatically put into the tiling scheme. Each time a new window is opened the tiling button or key has to be re-applied to include it in the tiling. Winfuncs generates two tiling modes, one displays the open windows in a rectangular matrix mode assigning the same area to each window and one stacks the windows in an orderly, regular manner in the upper left corner of the screen.
