Home computing pioneer Sir Clive Sinclair dies aged 81

Imago voragine.net
• , ,

His first home computer, the ZX80, named after the year it appeared, revolutionised the market, although it was a far cry from today’s models. At £79.95 in kit form and £99.95 assembled, it was about one-fifth of the price of other home computers at the time. It sold 50,000, units while its successor, the ZX81, which replaced it, cost £69.95 and sold 250,000. Many games industry veterans got their start typing programs into its touch-based keyboard and became hooked on games such as as 3D Monster Maze and Mazogs. The ZX80 and ZX81 made him very rich: in 2010 Sinclair told the Guardian: “Within two or three years, we made £14m profit in a year.”

In 1982, he released the ZX Spectrum 48K. Its rubber keys, strange clashing visuals and tinny sound did not prevent it being pivotal in the development of the British games industry.

But it flopped, and Sinclair Vehicles found itself in receivership by October of the same year. Reviews expressed concerns about the safety of driving a vehicle below the sight line of other motorists, as well as exposure to the elements. The following year, Sinclair sold his computer business to Amstrad.

The Limits of My Empathy for Covid-Deniers

Imago voragine.net
• ,

That sense of community requires a lot of humility, precisely the thing I am afraid that the onslaught of Covid denial stories is robbing me of by undermining my empathy for others. Martha helped me with perspective. This is not a problem of individual moral certainty or persuasion. This is a social problem with big structural issues. That does not absolve me of my responsibility for seeing the humanity in people I vehemently disagree with, but it does make me feel less guilty about being unable to save them.

I still do not understand how we can be in community with people who, by withdrawing from their social responsibility, are actively harming others. But, I do not think I have to understand it. I don’t think that I even have to be in community with Covid deniers. I have to somehow be in community with the people who are behaving in socially responsible ways without demonizing those who are not. Demonizing them turns my community into a reactionary force, which is precisely how the vaccines and masks became weaponized to begin with. It is a classic case of not becoming what you despise by losing focus on what you value.

Introduction to OpenBIM, Native IFC, and Open Source AEC | by Dion Moult

Go , go #OpenSource. Watch this video and see how data actually works!

This introduction to Native IFC covers all the basic concepts, code, libraries, and tools to get started building your own Open Source AEC tools.OSArch:

OpenBIM

Imago voragine.net
• , , ,

OpenBIM is the practice of BIM in a vendor-agnostic manner. For BIM to be vendor-agnostic, BIM data must be defined using an open data standard, and BIM practices should follow standardised workflows. An example of OpenBIM involves sharing BIM data using IFC and DXF file formats. An example of closed, or proprietary BIM, is sharing BIM data using RVT and DWG file formats.

Industry Foundation Classes (IFC)

Imago voragine.net
• , , ,

IFC (Industry Foundation Classes), is an Open Data schema and set of formats used to store OpenBIM data. It is developed and maintained by BuildingSMART International. IFC data can digitally describe many concepts, including:

Physical objects in our built environment (walls, slabs, columns, pipes)
2D and 3D geometry that represents objects or annotate objects
A diverse set of properties and attributes spanning many domains
Materials attributes and display colours
Construction planning, resource allocation, and scheduling
Quantification of elements
Roles and responsibilities of organisations and individuals
Design strategies and legal constraints
Analytical models for structural analysis, energy analysis, and light analysis

Fouce detalla las claves que apuntalan el negacionismo: «Simplifican la realidad, dan un marco de seguridad que hoy no tenemos, te hacen sentir parte de un colectivo y apelan a la libertad».

«Son gente perdida. No vas a convencer a un negacionista, porque salvo honrosas excepciones se mantienen en sus trece», concluye José Antonio Forcada. «Aunque no suele ser habitual, el motociclista Jorge Lis se dio cuenta de lo que era la realidad, pero llegó tarde».

What Is Aptio Setup Utility? How to Fix If Asus Stuck in It? [MiniTool Tips]

Imago voragine.net
• , , ,

To get rid of the setup utility, you need to follow these instructions below:

Step 1: Boot your Asus computer and wait for it to the Aptio Setup Utility window.

Step 2: Go to Security, expand the Secure Boot Control menu and ensure the secure boot option is disabled.

Step 3: Save and exit the tab, then restart your PC and wait for it to load Aptio Utility settings once again.

Step 4: Navigate to the Boot tab, disable these two options – Secure Boot and Fast Boot.

Step 5: Besides, enable CSM (Compatible Support Module).

Step 6: Save the change and restart the Asus computer. It should boot to the Windows operating system instead of Aptio Setup Utility.

Xsession

System-wide configuration of the Debian X session consists mainly of options inside the /etc/X11/Xsession.options file, and scripts inside the /etc/X11/Xsession.d directory. These scripts are all dotted in by a single /bin/sh shell, in the order determined by sorting their names. Administrators may edit the scripts, though caution is advised if you are not comfortable with shell programming.

« Les tiers-lieux sont le visage de la France post-Covid »

Imago voragine.net
• , , , ,

Selon moi, les tiers-lieux sont le visage de la France de l’après-Covid. A côté des grandes ETI, il y a cette économie territoriale qui renaît dans l’hyperproximité. Cela émergeait déjà auparavant : la transition numérique, écologique, la profonde remise en question de notre rapport au travail n’ont pas attendu la pandémie pour émerger comme une priorité, mais ces lieux apparaissent désormais de plus en plus comme le précipité de ces transitions…

Selon nos estimations, le territoire français comptera a minima environ 3500 tiers lieux en 2022, contre 1800 en 2018. Et je pense que l’exode des urbains qu’on observe déjà va renforcer cette dynamique. Ce qui est évident, c’est que les nouvelles générations bouleversent déjà le rapport au travail, elles réclament un meilleur équilibre entre vie professionnelle et vie perso…

«Tiers lieux» : Jean Castex encense la valeur trouvaille

Espaces de coworking pour allergiques au travail en solitaire, fabriques numériques, friches culturelles, mais aussi ateliers, cuisines ou jardins partagés… Encore méconnus du grand public, les «tiers lieux» ne pèsent pas bien lourd sur le papier : en 2021, on en comptait 2 500 en France et 150 000 personnes y travaillaient comme indépendants ou salariés de microentreprises pour un chiffre d’affaires cumulé d’environ 250 millions d’euros. Mais dans les métropoles comme dans des communes plus modestes, sur le terrain associatif et entrepreneurial, ces laboratoires de l’innovation laborieuse, technologique et sociale s’épanouissent «comme 100 fleurs», à en croire Patrick Levy-Waitz qui en paraphraserait presque Mao. Le président de l’association France tiers lieux et de la Fondation travailler autrement doit remettre ce vendredi à Jean Castex un rapport intitulé «Tiers lieux, nos territoires en action».

Ce n’est pas tous les jours que l’on voit un nouveau fablab pousser dans le département de l’Ariège. Or il en existe un peu partout, c’est une certitude. Cependant, celui-ci permet d’apporter encore plus de dynamisme au sein de ce village du Haut-Couserans. Oust se retrouve ainsi propulsé à la pointe de l’innovation 3D. Ce qui est un plus indéniable pour ce territoire de moyenne montagne situé au cœur du Parc Naturel Régional des Pyrénées Ariégeoises.
A priori, on pourrait croire que les impressions 3D sont abstraites. Mais en réalité, elles aident un bon nombre de d’entrepreneurs, artisans et artistes. Plusieurs projets sont menés par le fablab d’Oust, et d’autres prendront assurément corps.

Passe sanitaire : quelle surveillance redouter ?

Imago voragine.net
• , , , , , ,

Le passe sanitaire est la traduction d’évolutions techniques qui pourraient supprimer ces anciennes limites et permettre à cette forme de répression de s’appliquer à l’ensemble de la population, pour une très large diversité de lieux et d’activités.

Elle permet notamment de confier à des dizaines de milliers de personnes non-formées et non-payées par l’État (mais simplement munies d’un smartphone) la mission de contrôler l’ensemble de la population à l’entrée d’innombrables lieux publics, et ce, à un coût extrêmement faible pour l’État puisque l’essentiel de l’infrastructure (les téléphones) a déjà été financée de manière privée par les personnes chargées du contrôle.

Désormais, et soudainement, l’État a les moyens matériels pour réguler l’espace public dans des proportions presque totales.

Ce parallèle nous permet d’apporter une précision importante : qu’il s’agisse du passe sanitaire ou de la détection automatique des comportements « anormaux », ces systèmes ne nécessitent pas forcément un contrôle d’identité. Le logiciel d’imagerie qui signale votre comportement « anormal » se moque bien de connaître votre nom. De même, en théorie, le passe sanitaire aussi pourrait fonctionner sans contenir votre nom – c’est d’ailleurs ce que prévoyait la loi initiale sur la sortie de crise ou, plus inquiétant, ce que proposent désormais certaines entreprises en se fondant non plus sur le nom mais le visage. Dans ces situations, tout ce qui compte pour l’État est de diriger nos corps dans l’espace afin de renvoyer aux marges celles et ceux qui – peu importe leurs noms – ne se conforment pas à ses exigences.

Même dans son format le plus sophistiqué, l’efficacité du passe sur le plan sanitaire resterait toujours à démontrer – il demeure de nombreuses incertitudes, que ce soit sur la valeur des tests au bout de 72 heures, sur le taux de transmission même une fois vacciné, sur le cas des nouveaux variants, sur l’efficacité de la contrainte pour inciter la population à se faire vacciner, ou sur la durée de validité à retenir pour les tests de dépistage.

Ricing your system

Imago voragine.net

This is a book about understanding the parts of your system, and customize them as you please.

You won’t find anything related to GUIs (Graphical User Interfaces) in here. That’s primarily because GUIs aren’t standardized or «equal» on all unix machines. However, terminals are and for this fair reason I’m only going to treat CLIs (Command Line Interface) and TUI (Terminal User Interface.)

Rice burner

Imago voragine.net
• , , ,

Rice burner is a pejorative term originally applied to Japanese motorcycles and which later expanded to include Japanese cars or any East Asian-made vehicles. Variations include rice rocket, referring most often to Japanese superbikes, rice machine, rice grinder or simply ricer.

The term is often defined as offensive or racist stereotyping. In some cases, users of the term assert that it is not offensive or racist, or else treat the term as a humorous, mild insult rather than a racial slur.

Rice. r/unixporn dictionary

Imago voragine.net
• , , ,

«Rice» is a word that is commonly used to refer to making visual improvements and customizations on one’s desktop. It was inherited from the practice of customizing cheap Asian import cars to make them appear to be faster than they actually were – which was also known as «ricing». Here on /r/unixporn , the word is accepted by the majority of the community and is used sparingly to refer to a visually attractive desktop upgraded beyond the default.

Apophenia. How the Internet Transforms the Individual into a Conspiracy of One

Imago voragine.net
• , , , ,

The German psychologist Klaus Conrad called this premonitory state apophenia, defined as perceiving patterns that don’t actually exist and referring them back to an unseen authority who must be pulling the strings. It’s a theory he developed as an army medical officer specializing in head traumas under the Third Reich. Today, it’s analogized to political conspiracy thinking.

Conrad became famous for recognizing this oppressive emergence of patterns as a pre-psychotic state that he compared to stage-fright. It culminates in a false epiphany: an apophany is not a flash of insight into the true nature of reality but an aha experience (literally: Aha-Erlebnis) that constitutes the birth of delusion.

In an apophenic state, everything’s a pattern. And while Conrad’s stage-model uses the analogy of starring in your own one-man show, the narcissism of living online today provides plenty more. On Instagram you can filter your face, filter out unwanted followers, construct an image that you and your peers want to believe in—you’re living a private illusion, in public, that the world reifies with likes. For-profit data collection has literally “reorganized” the world to revolve around you. As you wish it—or they will it.

The true epiphany, I want to argue, is that you’re the one pulling the strings. Enlightenment is to realize you have more agency than your push-notifications would have you believe.

The sad state of font rendering on Linux

Imago voragine.net
• , ,

onts are vector data that gets rasterized when displayed to the user. Computer displays are low-DPI devices for complex reasons, and such DPI (96) is not enough to display fonts without a myriad of trade-offs. Most notable are sub-pixel rendering, sub-pixel positioning, font hinting and anti-aliasing. You can read up more here and here if you want the full background.

Each operating system approaches font rendering differently. To get Windows-like rendering that I prefer, anti-aliasing, sub-pixel rendering, sub-pixel positioning and font hinting based on byte code embedded into fonts – basically, every step of the technological progress made in the last 30 years – need to be active.

Better font rendering in linux

Imago voragine.net
• , ,

If we’re not running a full blown desktop environment like GNOME, KDE or XFCE, the chances of getting good font rendering in a post Xorg installation after a default linux base (think of arch or voidlinux) install is zero. This guide serves as a list of todo items to get decent font rendering with these sort of installs.

The end game

“The goal is justice, the method is transparency. It’s important not to confuse the goal and the method.”

—Julian Assange

…three innovations had already set WikiLeaks apart from other publishers: the use of encrypted dropboxes to protect the identity of sources, partnerships with established media organisations to add audience reach and institutional protection, and a preference for making whole archives public rather than curating a drip-feed. “You can’t publish a paper on physics without the full experimental data and results; that should be the standard in journalism,” argued Assange.

Diferencia entre logo, logotipo, isotipo, imagotipo, isologo

Imago voragine.net
• , , , ,

Logo: A pesar de ser muy común suele ser el peor utilizado, la palabra logo viene del nombre logotipo, cuando decimos logo es para referirnos a toda plasmación de una marca. Los logotipos suelen ser puramente Tipográficos (fuentes) y representativos que pueden mostrar la verdadera identidad de una marca, ejemplo: Lego, Google, Coca-cola.

Isotipo: Un isotipo se refiere a la parte simbólica o icónica de la marca, un isotipo es cuando reconocemos la marca sin necesidad de que a esta la acompañe algún texto, con el fin de que las personas lo vean y este pueda ser entendido por sí mismo, ejemplo: McDonald’s, Niké, Dove.

Imagotipo:Es un ícono textual en el que texto y símbolo se encuentran claramente diferenciados, e incluso pueden funcionar separados, normalmente el ícono se implementa en la parte superior y la tipografía (texto) en la parte inferior. En algunos empaques de productos veremos símbolos o en otros veremos tipografía (texto), Ejemplo: Carrefour, Pepsi, La coste.

Difference Between PDF and PDF/ A

There is also a different type of PDF known as PDF/A. PDF/A is a subset of PDF that is meant for archiving information. In order to preserve the information in the file and to ensure that the contents will still appear as it should even after a very long time of storage, PDF/A sets stricter standard than those used by PDF.

PDF/A is a special type of PDF meant for archiving documents
PDF/A does not allow audio, video, and executable content while PDF does
PDF/A requires that graphics and fonts be embedded into the file while PDF does not
PDF/A does not allow external references while PDF does
PDF/A does not allow encryption while PDF does

Cathy O’Neil : pour une éthique des algorithmes

Quel est son parcours et d’où lui est venue sa passion pour les mathématiques ? Pourquoi appelle-t-elle les algorithmes des “armes de destruction mathématiques” ? Comment ces nouveaux pouvoirs algorithmiques transforment-ils les pratiques professionnelles de la société ?

Quoi de plus neutre qu’un ordinateur ? Quoi de plus a priori objectif qu’une suite de calculs, qu’une série d’opérations mathématiques ? Quoi de plus éloigné d’une opinion finalement qu’un algorithme ? Et bien tout justement. Parce qu’ils sont programmés par des humains qui sont eux perclus de biais, parce qu’ils tentent d’objectiver des réalités qui sont plus complexes que ce que peut décrire une seule suite mathématique, parce qu’enfin derrière chaque algorithme il y a une intention et qu’une intention n’est pas neutre. Pour notre invitée du jour, les algorithmes sont devenus des weapons of math destruction, des armes de destruction mathématique.

La mathématicienne, informaticienne et activiste Cathy O’Neil est notre toute dernière invitée de l’année. Bienvenue dans la Méthode scientifique.

Enthusiastic Amateurs Advance Science As They Hunt For Exotic Mushrooms

Imago voragine.net
• , ,

By one estimate, there are between 2.2 million and 3.8 million species of fungi — and more than 90% of them aren’t cataloged.

But mycologists (as fungus professionals are known) do get a big boost from a surprisingly sophisticated world of amateurs — both those who tromp through the forests observing oddball species, as well as those who have helped build a community that links the amateurs with the pros.

Sometimes the amateurs come up with stunning discoveries.

Consider the story of Taylor Lockwood, a 74-year-old mushroom enthusiast and professional photographer. This spring, we met in the hills of West Virginia, where he has been prowling the countryside in a van he has converted into a camper, a photo studio and a workshop.

This post is an explanation about my Openbox configurations and how to use them. Openbox is my favourite window manager, and it’s the first window manager I use. At first, I didn’t even know how to make Openbox worked. When I installed it and ran it, I just got a blank black screen and didn’t even know how to launch any application. I followed several guide but couldn’t understand it, I gave up. But after a while, I heard about Crunchbang. It came with preconfigured Openbox, and a complete set of software to make Openbox usable as a desktop. I really enjoyed Crunchbang and kept playing around with it. Playing with Crunchbang meaned learning. I learned a lot about configuration files and theming. Also about modular applications that could work right with Openbox. I also tried a lot other popular window managers, but still couldn’t leave Openbox.

Snapchat Can Be Sued Over Role In Fatal Car Crash, Court Rules

Imago voragine.net
• ,

Three young men got into a car in Walworth County, Wis., in May 2017. They were set on driving at rapid speeds down a long, cornfield-lined road — and sharing their escapade on social media. As the 17-year-old behind the wheel accelerated to 123 miles per hour, one of the passengers opened Snapchat. His parents say their son wanted to capture the experience using an app feature — the controversial «speed filter» — that documents real-life speed, hoping for engagement and attention from followers on the messaging app. It was one of the last things the trio did before the vehicle ran off the road and crashed into a tree, killing all of them. Was Snapchat partially to blame? The boys’ parents think so. And, in a surprise decision on Tuesday, a federal appeals court ordered that the parents should have the right to sue Snap.

Se hace pagar a Ana Iris Simón, manchega y de clase trabajadora, una especie de multa por citar en sus páginas a Ramiro Ledesma Ramos, fundador de Falange, aunque sea una cita de derechas entre otras muchas de izquierda y centrándose en la admiración juvenil que profesba por el espíritu justiciero de Don Quijote. Curiosamente, esa factura política no se ha pasado a la novelista Cristina Morales, ni al político Iñigo Errejón (que cita la frase «Solo los los ricos pueden permitirse no tener patria») ni al grupo de rock Fuerza Nueva, que también usa referencias falangistas.
