There are six steps in the original technique:

Decide on the task to be done.
Set the pomodoro timer (traditionally to 25 minutes).
Work on the task.
End work when the timer rings and put a checkmark on a piece of paper.
If you have fewer than four checkmarks, take a short break (3–5 minutes), then go to step 2.
After four pomodoros, take a longer break (15–30 minutes), reset your checkmark count to zero, then go to step 1.

For the purposes of the technique, a pomodoro is the interval of time spent working.

Placa base del Thinkpad X210

I have not personally used the ThinkPad X201 over an extended period of time. Despite this fact, during the month I have spent with the X210, it is easy to sense 51nb’s effort in recreating a modern ThinkPad X201. Starting by keeping the exceptionally comfortable 7-row keyboard and TrackPoint, adding support for M.2 and mSATA SSDs, finding the WUXGA upgrade, and topping it off with a user-configurable BIOS to maximise performance with the 8th generation mobile chips, upgradable DDR4 RAM slots, … These all have made the X210 a truly memorable and excellent example among the contemporary laptops.

However, this recreation requires a keen hand to assemble, upgrading the motherboard and display panel is not a job for the faint of heart. The BIOS is not perfect either, especially in regards to power consumption and the battery’s status reporting. Thankfully, this does not deal a fatal blow to its practical usability, and the latter has since been fixed with later BIOS updates.

Our test sample, as mentioned numerous times before, was hastily assembled. Despite this however, the laptop demonstrated great stability even with sustained usage and torture testing. The laptop, perhaps predictably, boots quickly and is highly responsive. Thermal performance is nothing less than staggering, to the point that I have to repeatedly make sure that the thermal measuring tools and software are performing properly.

In conclusion, the X210 is a unicorn in the realm of sub-notebooks: retaining the RJ-11 modem port while extracting the full potential of the 8th generation mobile processors; keeping the comfortable and familiar input devices while adding support for cutting edge technologies like PCIe NVMe SSDs; ensuring support for the original LVDS panels while adding support for greatly improved EDP-interfaced IPS panels… The X210 skillfully combines cutting edge technologies with classic elements that make a ThinkPad great for us enthusiasts. The X210 is not just a bottle of fine wine or a fresh breeze through a medieval castle – it’s really much more than that. A faithful recreation from a passionate community of ThinkPad lovers, that’s what the X210 really is.

The first thing to go was the beloved, clacky, positive-action keyboards, replaced by Macbook-style chiclet keyboards that wore out much faster, but at least the keyboards were easily swapped out when they started to falter. Then came new submicro designs that made swapping keyboards into a one-hour procedure that had to be performed by a professional who would have to virtually totally disassemble the computer.

The same forces made drive-swaps harder and harder. I used to order a Thinkpad with the smallest, cheapest drive available and then throw it away on arrival and replace it with a third-party, 1TB SSD. Now I just order the Thinkpads with 1TB SSDs and pay a premium for them (these custom options can add weeks to the build/delivery time, too) — thankfully, the price-gap on Lenovo’s 1TB SSDs and third party drives has narrowed.

And now, the Thinkpad X-series systems have eliminated their Ethernet ports and require users to carry (and not lose or break) a dongle to use wired internet.

51NB, a group of Chinese enthusiasts buy up classic, pre-Lenovo Thinkpad chassis and manufacturers new motherboards for them with modern CPUs and other hardware. They started with a run of Thinkpad « X62 » system (X61s with a new motherboard) and then branched out into Thinkpad « X210″s — an X201 with a Core i7 8550u (4 cores, turbo boost up to 4GHz); 2× DDR4 SODIMM slots; 2× mini PCI Express slots; an M.2 NVMe slot; a 3.5” SATA bay; a 12.6 inch, 2880×1920, 450 nits, wide gamut display; Mini DisplayPort & VGA out; 3× USB 3.1 ports; an SD reader and gigabit Ethernet (no dongle required!).

“Less than 20 companies actually own more than 80% of the internet capacity, which is the storage and the compute,” de Spiegeleer told me. “It really needs to be something like electricity. It needs to be everywhere and everyone needs to have access to it. It needs to be cost effective, it needs to be reliable, it needs to be independent.”

You use the internet to send a message on a messaging service to a family member across town. As you click Send, the message will most likely travel across your continent and perhaps across an ocean, hit a number of companies’ servers along the way, then ping back, likely on a different route, hitting multiple other companies’ servers as well before arriving at a relatively local switch, ISP, wires, WiFi, and then making it down to your mom’s phone.

The alternative? In a mesh distributed internet, your message to mom might make a couple of hops over local computers, maybe a local ISP, and ping right down to her having traveled not much more than the straight-line distance between you and your favorite parent.

El código Konami (Konami Code, también conocido como Konami Command o Contra Code) es un truco que puede ser usado en ciertos videojuegos de Konami, que normalmente activa alguna opción secreta. El código fue usado por primera vez en la versión de Gradius para la videoconsola NES, en 1986. En la partida, el jugador pulsa la siguiente secuencia de botones en el controlador:

Decisions not Options

When making decisions, these are the users we consider first. A great example of this consideration is software options. Every time you give a user an option, you are asking them to make a decision. When a user doesn’t care or understand the option, this ultimately leads to frustration. As developers, we sometimes feel that providing options for everything is a good thing, you can never have too many choices, right? Ultimately these choices end up being technical ones, choices that the average end user has no interest in. It’s our duty as developers to make smart design decisions, and avoid putting the weight of technical choices on our end users.

In 1961 the astronomer Frank Drake proposed what became known as the Drake equation, setting out seven factors that would need to be known to come up with an estimate for the number of intelligent civilisations out there. These factors ranged from the the average number of stars that form each year in the galaxy through to the timespan over which a civilisation would be expected to be sending out detectable signals.

Under the strictest set of assumptions – where, as on Earth, life forms between 4.5bn and 5.5bn years after star formation – there are likely between four and 211 civilisations in the Milky Way today capable of communicating with others, with 36 the most likely figure.

The team add that our civilisation would need to survive at least another 6,120 years for two-way communication. “They would be quite far away … 17,000 light years is our calculation for the closest one,”

Pour donner une idée de l’ampleur du problème, Gabor Szathmari a réenregistré d’anciens noms de domaine pour plusieurs cabinets d’avocats qui avaient fusionné, et mis en place un serveur de courrier électronique. Et, sans rien pirater, il affirme avoir reçu un flux constant d’informations confidentielles, y compris de la correspondance bancaire, des factures d’autres cabinets d’avocats, des documents juridiques sensibles de clients, et des mises à jour LinkedIn. (Il a ensuite restitué les noms de domaine à leurs propriétaires d’origine).

Or, selon le chercheur, il serait facile d’utiliser la même technique pour commettre des fraudes. « En rétablissant une boutique en ligne fonctionnant autrefois sur un nom de domaine désormais abandonné, des acteurs malveillants pourraient télécharger les pages web originales depuis archive.org, puis prendre des commandes et effectuer de nouveaux paiements en se faisant passer pour une boutique en ligne tout à fait fonctionnelle », a-t-il déclaré par courriel. « Si l’ancienne boutique en ligne disposait d’un système de gestion de la relation client (CRM) ou d’un MailChimp, les criminels pourraient accéder à la liste des anciens clients en reprenant ces comptes avec un mot de passe réinitialisé par courrier électronique »

But, in reality, these efforts started years ago, in 2014, when the Drupal project first moved in to replace « master/slave » terminology with « primary/replica. »

Drupal’s move was followed by the Python programming language, Chromium (the open-source browser project at the base of Chrome), Microsoft’s Roslyn .NET compiler, and the PostgreSQL and Redis database systems.

…términos como « master/slave » se llevan usando años no solo en el ámbito del desarrollo, sino también al hablar por ejemplo de las viejas configuraciones de discos duros.

Dichos conceptos siempre han suscitado cierta controversia por sus connotaciones raciales, y ahora varias empresas están impulsando cambios para dejar de usar esos términos y sustituirlos por otros más neutros. Por ejemplo usar « principal » (main), « por defecto » (default), « raíz » (root) o « primario » (primary) para sustituir al concepto de « maestro » (master).

Lo mismo ocurre con las « listas negras » y las « listas blancas » que por ejemplo usamos para admitir o bloquear ciertas palabras en los comentarios que llegan a un blog. En lugar de esos conceptos se quieren usar « lista de permitidos » y « lista de exluidos/denegados ».

Portada 24 de mayo 2020 del New York Times

The New York Times prepared a powerful front page for its May 24 print edition, marking the somber milestone of 100,000 coronavirus deaths in the United States.

The newspaper listed the names of 1,000 people who died of COVID-19 — just 1% of the total death toll.

The newspaper staff combed through obituaries and death notices for people whose cause of death was listed as COVID-19, and listed people’s names, ages, and facts about their lives.

Aunque no hay un consenso general, hasta ahora no existe evidencia suficiente que demuestre algún daño inmediato en la salud provocado por las redes 5G. Como aún persisten dudas, la investigación seria y el debate continúan.

Sin embargo, el 5G no está ligado a la propagación de la pandemia. Esta acusación está perjudicando a las críticas centradas en los impactos políticos y sociales de esta nueva tecnología.

Lo primero que me chocó es la gama de colores del mapa. Lo normal es que se use un color y se aplique una tonalidad que se va oscureciendo conforme los valores son más altos. En este caso el valor más alto es de un color diferente de la gama, El negro no es marrón.

Además, la diferencia de color es muy grande respecto a Italia con una variación del 5%. No sé si esto es intencionado o tan solo un error de diseño. Este mapa va a la galería de ejemplos de malas visualizaciones para mis alumnos. Para colmo, los datos no eran correctos.

Como ya se dieron cuenta @resd9 y @A_Sorines el dato de Bélgica era erróneo en vez de 15,70% era 65,67%. El mapa lo publicó la Vanguardia y ha rectificado el dato aunque mantiene el color negro.

Amish lives are anything but anti-technological. In fact on my several visits with them, I have found them to be ingenious hackers and tinkers, the ultimate makers and do-it-yourselfers and surprisingly pro technology.

Some orders require the buggy to be an open carriage (so riders – teenagers, say – are not tempted with a private place to fool around); others will permit closed carriages. Some orders allow tractors on the farm, if the tractors have steel wheels; that way a tractor can’t be “cheated” to drive on the road like a car. Some groups allow farmers to power their combine or threshers with diesel engines, if the engine only drives the threshers but is not self-propelled, so the whole smoking, noisy contraption is pulled by horses. Some sects allow cars, if they are painted entirely black (no chrome) to ease the temptation to upgrade to the latest model.

When cars first appeared at the turn of last century the Amish noticed that drivers would leave the community to go shopping or sight-seeing in other towns, instead of shopping local and visiting friends, family or the sick on Sundays. Therefore the ban on unbridled mobility was aimed to make it hard to travel far, and to keep energy focused in the local community.

Turns out the Amish make a distinction between using something and owning it. The Old Order won’t own a pickup truck, but they will ride in one. They won’t get a license, purchase an automobile, pay insurance, and become dependent on the automobile and the industrial-car complex, but they will call a taxi.

Al igual que las vacunas que se están desarrollando requieren de un tiempo de precaución para probar su fiabilidad, las tecnologías también lo necesitan para garantizar que no producirán daños sociales y brechas inasumibles en estados democráticos, así como para que no lleguen a generar precedentes peligrosos para nuestros derechos.

en primer lugar, que sean temporales. Es decir, que cuando termine el estado de alarma, dejen de funcionar. En segundo lugar, que se sepa cuáles son los propósitos y que se cumplan, lo que implica no seguir añadiendo capas con nuevas funcionalidades en cada actualización que extiendan los propósitos iniciales. Y por último, que se conozca quiénes tienen acceso a los datos que se recopilan y que no se permita el acceso a ellos a nadie más.

Estas empresas han optado por la opción descentralizada, algo que sin duda beneficia a la privacidad, pero por contra, merma el poder de decisión de los gobiernos y poderes públicos.

La actual situación nos debe servir para reflexionar acerca de la tecnología que queremos, donde la ciudadanía, informada, tome decisiones sobre qué aplicaciones o datos da y a qué actores del ecosistema digital. Los sistemas de cajas negras no deberían ser aceptables en tiempos de pandemia, pero tampoco en ningún otro momento.

Las tecnologías no son ni buenas ni malas ni neutrales, y en muchos casos depende del uso que se les dé o se les permita.
