Il sonno è una strana bestia. Perché ce n’è sempre troppo poco, soprattutto nel nostro mondo super stimolato e illuminato artificialmente. E la nostra percezione, in una economia del tempo libero (cioè fuori dall’orario di lavoro, quando diventiamo tutti consumatori e quindi è meglio se siamo svegli e spendiamo o guardiamo ma pubblicità) è enormemente falsata.

Money quote: “One 2014 study of more than 3,000 people in Finland found that the amount of sleep that correlated with the fewest sick days was 7.63 hours a night for women and 7.76 hours for men. So either that is the amount of sleep that keeps people well, or that’s the amount that makes them least likely to lie about being sick when they want to skip work. Or maybe people who were already sick with some chronic condition were sleeping more than that—or less—as a result of their illness. Statistics are tough to interpret. Isolated studies are tougher. “

Questo articolo è tornato a galla dopo un annetto o poco più che lo avevo citato. Lo riprendo per una seconda volta con piacere, perché il tema è forte: non tutti i big data sono tali. In particolare, qui si argomenta - con un interessante esperimento - l'idea che in molti casi si possa fare più e meglio con la riga di comando (perché la pipe parallelizza i calcoli su tutti i core) su un semplice laptop che non con i giganti del cloud con le soluzioni pensate per i big data. È anche una bella lezione su come ottimizzare una sequenza di comandi.

Money quote: "One especially under-used approach for data processing is using standard shell tools and commands. The benefits of this approach can be massive, since creating a data pipeline out of shell commands means that all the processing steps can be done in parallel. This is basically like having your own Storm cluster on your local machine. Even the concepts of Spouts, Bolts, and Sinks transfer to shell pipes and the commands between them. You can pretty easily construct a stream processing pipeline with basic commands that will have extremely good performance compared to many modern Big Data tools."

Da anni, parlando con scienziati e ricercatori di tutto il mondo, tutti quanti sostengono che il principale problema delle energie rinnovabili che generano corrente elettrica è la conservazione: le batterie sono un problema enorme, mentre petrolio, carbone e legna sono forme naturali di accumulazione di energia. Beh, salta fuori che si può ricorrere anche a un altro sistema: l'aria compressa. Ed è un'idea molto, molto interessante.

Money quote: "Compressed air energy storage (CAES) is considered to be an important component of a renewable power grid, because it could store surplus power from wind turbines and solar panels on a large scale. However, in its present form, the technology suffers from large energy losses and depends on natural gas to operate."

Makers all'opera: come rifare da zero il gatto della fortuna, quello che manda avanti e indietro la zampina. Per riuscirci, va prima smontato e guardato molto bene.

Money quote: "“What I can not create with an Arduino, I do not understand”, so we then proceed to recreate a lucky cat under Arduino digital control."

La drammatica e traumatica bellezza dei grandi monumenti e delle grandi opere mentre vengono costruite

Money quote: "The construction of great landmarks is often thought of in terms of statistics—how high, how big, how wide—or hyperbole: the tallest, the longest, the most amount of concrete. But there’s always more to the story than just figures. Many landmarks are built under clouds of controversy. In February 1887, just after construction began on the Eiffel Tower, a group of artists and writers published a letter in Le Temps newspaper, “Protest Against the Tower of Monsieur Eiffel,” proclaiming their distaste for what they called a “stupefying folly.” A more humorously cutting criticism came from the French writer Léon Bloy, who called the tower a “truly tragic street lamp.”"

Instapaper è tornata indipendente (è uscita da Pinterest e se la sono ricomprata i suoi creatori). E ha tagliato via l'Europa...

Money quote: "Today, we’re announcing that Pinterest has entered into an agreement to transfer ownership of Instapaper to Instant Paper, Inc., a new company owned and operated by the same people who’ve been working on Instapaper since it was sold to betaworks by Marco Arment in 2013. The ownership transfer will occur after a 21 day waiting period designed to give our users fair notice about the change of control with respect to their personal information."

Si può argomentare tutto, per carità. Ma sostenere che oggi la gente non risponda più al telefono, e farlo portando se stessi come esempio, mi sembra un po' eccessivo anche per uno spirito aperto al mondo.

Money quote: "No one picks up the phone anymore. Even many businesses do everything they can to avoid picking up the phone. Of the 50 or so calls I received in the last month, I might have picked up four or five times. The reflex of answering—built so deeply into people who grew up in 20th-century telephonic culture—is gone."

Volete partecipare al programma di protezione super avanzata del vostro account con Google? Se rientrate nelle categorie giuste, potreste farcela (ma in generale, secondo me è possibile: casomai fatemi sapere). In pratica, vi danno il generatore di codici "fisico", la chiavetta della banca, e vi blindano le app.

Money quote: "Il programma di protezione avanzata tutela gli account Google personali di figure professionali come giornalisti, leader aziendali e candidati politici che sono ritenuti maggiormente a rischio di attacchi mirati."

Sono praticamente degli Ape e degli Ape Poker a motore elettrico. Ma in Germania stanno diventando una cosa notevole. E ne producono sempre di più.

Money quote: "The WORK and WORK L StreetScooter models have been available to external customers since summer 2017. Industries that have a need for customized electric vans include - in addition to municipalities and craft workshops - energy suppliers, waste disposal companies, airports, facility management enterprises, and catering companies. StreetScooter will produce variants tailored to serve a variety of individual needs with such features as variable loading volumes that include power supply, refrigerated containers, and tilting load platforms.

StreetScooters have been being deployed successively in Deutsche Post DHL's delivery fleet since 2013. At present, the Group is already using around 6,000 of these electric vehicles, which have covered over 26 million kilometers and save around 20,000 tons of CO2 per year. With these vans and the 12,000 or so electric e-bikes and e-trikes, Deutsche Post DHL is operating the biggest electric fleet in Germany."

Ritrovare e studiare i font che hanno fatto la storia: ecco "Chicago" del Macintosh originale

Money quote: "I’m a huge fan of Susan Kare’s Chicago bitmap typeface. If you’re older than about 25, you know it as the Macintosh system font from the 1980s into the 1990s, or from its encore run on the little screens of the early iPods. But its celebrity obscures solid craft. It’s hard for small bitmap letters to project a unique and coherent personality, but Chicago does it: a high-contrast sans serif with a handful of key flourishes creating a friendly affect. It looks like this:"

Avete presente la pioggia di email che chiedevano il rinnovo esplicito o implicito del vostro consenso al trattamento dei vostri dati personali ai sensi della GDPR? Erano frutto dell'ignoranza, della paura o di cattivi suggerimenti legali. E potrebbero pure portare a multe perché denotano una condotta illegale.

Money quote: "Like Vitale, Wood emphasised that asking for marketing consent from people who had not given it initially could be illegal. “It’s also important to remember that in some cases it may not be appropriate to seek fresh consent if you are unsure how you collected the contact information in the first place, and the consent would not have met the standard under our existing Data Protection Act,” he said."

Non poche polemiche per un bacio dato dal presidente delle Filippine Rodrigo Duterte a una elettrice sul palco di una conferenza di qualche tempo fa. La cosa è meno grafica di quel che più sembrare, ma la parte agghiacciante è la simbologia e il senso di quel che è successo.

Money quote: "Filipino Senator Risa Hontiveros also said President Rodrigo Duterte "acted like a feudal king" after he kissed a married woman in front of 3,000 people in Seoul, South Korea. The woman involved later said that there was "no malice" in the kiss."

Questo presidente degli Stati Uniti si sta dimostrando sempre più strano, veramente atipico, e anche straordinariamente umano e normale nelle sue piccolezze e nella sua totale mancanza di senso dello Stato. Un uomo medio, un perfetto grillino d'Oltreoceano, direi. Chi non simpatizzerebbe con il suo sistema di archiviazione dei documenti, suoi e altrui? E con il lavoro di chi deve recuperare e ricucire il tutto, per preservarlo ai fini della normativa sulla trasparenze e sull'accesso ai documenti pubblici?.

Alla fine, è più umana la mente dell'autocrate che non quella del burocrate. È questo il segreto del suo successo?

Money quote: "It was a painstaking process that was the result of a clash between legal requirements to preserve White House records and President Donald Trump’s odd and enduring habit of ripping up papers when he’s done with them — what some people described as his unofficial “filing system.”"

Fotografare la Luna e i gabbiani con un Game Boy e un obiettivo Canon. Meraviglia.

Long read: droni a vela che permettono di andare là dove praticamente nessuno è mai andato prima e scoprire cose che voi umani... Dopotutto gli oceani sono uno degli spazi più misterioso nell'esperienza umana. Altro che cosmo.

Money quote: "“We’re talking about a place that is a long way from anywhere, that few people have ever been to,” Block says. “Then I’m sitting in my office, and the images start to appear of the sharks doing dives in these day and night patterns. What I saw was almost unbelievable.” The sharks appeared to be diving toward a layer of deep ocean teeming with fish, which suggested they came to the Cafe to dine. Block has since set out with a dozen researchers to sail alongside the robotic scouts and learn whether some special kind of food, or perhaps a romantic getaway, helps draw the sharks to the middle of nowhere. “This is one of the largest migrations, one of the largest stories, and we don’t know enough about it or about what goes on in the ocean overall,” she says. “I think this type of technology will help us fill in the gaps at a crucial time for our planet.”"

La bellezza per l’artista e per lo scienziato, secondo Richard Feynman (magari) e soprattutto per il tizio di Medium che ha scritto il suo compitino.

Money quote: “The artist and the scientist both see and appreciate the aesthetically profound, but they don’t always fully experience what the other person experiences when they look at something.”
