2018/09/19: Notifications are no longer used to notify you of anything—they’re used by apps to beg for attention.
Facebook appears to be increasingly sending meaningless notifications to people who use the site less and less in hopes of enticing them back to it.
Twitter, a platform where literally anyone on Earth can pick a fight with you at any time of day and deliver it directly to your phone’s lock screen.
Doctorow: I have trained all the people who can send me messages using those protocols that the only time to send me a message over them is when something is extremely time-sensitive. I check in on everything else (email, Twitter mentions, etc) several times a day, but I don't have anything, on any of my devices, that interrupts me to tell me that someone, somewhere is thinking about me.
2018/09/17: in che rapporto stanno la firma digitale/qualificata e la conservazione? Per garantire la validità giuridica di un documento è necessario che questo sia conservato in un sistema a norma prima della scadenza del certificato ?
Secondo questo articolo (grazie a Michele Gentili per averlo condiviso) https://t.co/bCCGMtI3CT
oppure secondo quanto dicono i notai in questo (davvero interessante anche se discutibile) documento dedicato alla tematica https://www.notariato.it/sites/default/files/1-2017-DI.pdf
sembrerebbe di sì.
Personalmente la vedo molto diversamente e credo anzi che i citati documenti denotino una sostanziale diffidenza, quasi paura, nella tecnologia, specialmente nella crittografia, alla base della firma digitale.
Sarebbe interessante capire anche il motivo di questa diffidenza (mancata reale comprensione ? cattiva comunicazione da parte degli informatici/matematici ?) specialmente se si pensa che invece ci si fida quasi ciecamente della modalità "analogica" e della firma autografa che non solo sono facilmente alterabili ma la cui verifica è affidata a tecniche (la grafologia forense) la cui affidabilità è ben lontana dall'essere vicina agli standard previsti per la firma digitale. (a proposito segnalo il seguente articolo illuminante http://www.ratiolegisweb.it/…/la-grafologia-forense-alcune…/)
Termino con alcune domande correlate :
- ci è chiaro quale sia realmente il modello di conservazione che prevede il cad, specie dopo la "correzione" del comma 1-bis dell'art. 44, che impone il versamento nel sistema di conservazione tutti i documenti anche afferenti a procedimenti non conclusi ?
- ci è chiaro perchè un certificato scade dopo 3 anni ? è un'esigenza tecnica o commerciale ? (non ditelo ai notai, ma in realtà attualmente l'algoritmo più delicato in termini di possibilità di hacking è quello per ottenere l'hash e non la crittografia dell'impronta...)
- se la marca temporale che è identica ad una firma vale 20 anni perchè non si può fare anche per i certificati ?
- per lo stesso motivo per cui la marca dura 20 anni, il riferimento temporale dato dal protocollo, se inviato il giornaliero in conservazione come prevede la norma, può considerarsi indefinito ? E così quindi la validità legale del documento financo non conservato ?
2018/09/18: They stopped cars crossing the city and got rid of street parking, as people looking for a place to park is what causes the most congestion. They closed all surface car parks in the city centre and opened underground ones and others on the periphery, with 1,686 free places. They got rid of traffic lights in favour of roundabouts, extended the car-free zone from the old city to the 18th-century area, and used traffic calming in the outer zones to bring the speed limit down to 30km/h.
The benefits are numerous. On the same streets where 30 people died in traffic accidents from 1996 to 2006, only three died in the subsequent 10 years, and none since 2009. CO2 emissions are down 70%, nearly three-quarters of what were car journeys are now made on foot or by bicycle, and, while other towns in the region are shrinking, central Pontevedra has gained 12,000 new inhabitants. Also, withholding planning permission for big shopping centres has meant that small businesses – which elsewhere have been unable to withstand Spain’s prolonged economic crisis – have managed to stay afloat.
2018-09-19: In the study, much of the assumed transformation is achieved by near-universal digitalization. The authors focus on end-use energy services, suggesting that most of these could be delivered far more efficiently using microelectronics. Household and commercial electricity use could be slashed as multiple pieces of equipment are foregone for a smart phone—whose 5 Watt power consumption would substitute for 450 Watts of consumption from cameras, calculators, TVs, game consoles, DVRs, radios, scanners, tablets, stereos, alarm clocks, GPS, weather stations, video cameras, etc. Some of these uses have already been taken over by smart phones. Moreover, the authors assume that household appliances will all be connected to the Internet of Things, to allow for their optimal operation and seamless availability for demand response.
What’s not mentioned in the Grubler scenario is that universal digitalization would require a robust, dependable electricity supply and electronic communications network. This would entail substantial new infrastructure and electricity demand to accommodate data transmission, storage, and processing for nearly every piece of equipment on Earth. It would also require a great deal of copper. And it would all have to work together seamlessly 24/7.
but... industrial uses of energy (especially for high-temperature process like cement making) will be difficult to de-carbonize, and such processes figure into nearly all supply chains. The Grubler scenario excludes aviation and shipping from consideration.
2018/09/16: How bad is the situation with plastic pollution? Rather bad, by all means. Citing from a recent paper by Geyer et al., more than 8 billion tons of plastic have been produced since the 1950s. Of this mass, 9% percent was recycled, 12% was incinerated, the rest is still around. It is this mass of plastics, billions of tons, which generates the pollution we see today. It is almost one ton of plastic waste for every human being living today. Imagine if it were magically to appear in your living room: one ton for every member of your family.
Still following Geyer et al., we learn that in 2015 the world produced 380 million tons of plastics from fossil hydrocarbons. To get some idea of how polluting this mass is, we can compare it to the total carbon emissions produced by hydrocarbon combustion, which today can be estimated to be around 9 billion tons per year. As an order of magnitude comparison, we can say that about 4% of the fossil hydrocarbons we extract become plastics.
4% doesn't seem to be a large amount, but it is not negligible, either. Apart from the horrible state of some beaches, the islands of plastics in the oceans, it is a lot of carbon pumped into the ecosystems and its effects are scarcely known, especially on humans: we are all eating microplastic particles, today. What will that do to our health, nobody knows -- we are all guinea pigs in a great experiment. The long-run problem is that all this plastic is made from fossil hydrocarbons, it is going to be gradually oxidized and turned into gaseous CO2. Then, it will contribute to global warming.
is bioplastic the solution to the problem? As it often happens, quantification makes short work of ideas that seemed to be good in theory. Today, bioplastics are made mainly from cereals (corn) or directly from sugar. According to the data from Statista, the world's production of sugar was about 170 million tons in 2017, less than half the amount needed to make the currently produced amounts of plastics even in the wildly optimistic assumption of a 100% efficient process. About grain, the data tell us that in crop year 2016/2017, a total of approximately 2.62 billion metric tons of grain were produced worldwide. Again in the wildly optimistic assumption of a 100% efficient production process, it means we should set aside about 15% of the world's grain production - more realistically about 20%-25%. Then, of course, efficiency can be improved and we may find ways to make plastic out of plants not used as food. But, at present, it is the way things stand.
There is just so much that agriculture can do: it can't feed more than 7 billion people and, at the same time, provide fiber, chemicals, and fuel for everybody.
it would be perfectly possible to develop and implement international agreements that would curb the use of plastics made from fossil fuels and eventually ban it completely. That implies changing something in our everyday life: the "overpackaged" products that today are so common in supermarket aisles would have to disappear. But packaging is not evil: it is a way to store food more efficiently. We need to learn how to be much more efficient with it.
2018/09/19: 15 employers in past year, including Uber, advertised jobs on Facebook exclusively to one gender.
In a statement, Facebook spokesman Joe Osborne said, “There is no place for discrimination on Facebook; it’s strictly prohibited in our policies. We look forward to defending our practices once we have an opportunity to review the complaint.”
The company has previously said that giving advertisers the ability to target employment ads by sex and age does not facilitate discrimination.
In response to other suits, Facebook has argued that it is not liable for the content its users—in this case, advertisers—post on its platform.
2018/20/09: Nelle città medie si può sperimentare dandosi il tempo che ci vuole (lo short termism è il grande male della nostra epoca) e traendone le giuste conseguenze. Soluzioni nuove ai grandi problemi delle nostre comunità che vanno dal traffico alle emissioni di gas serra, dai necessari nuovi modelli di welfare all’incentivazione all’imprenditoria, richiedono laboratori sperimentali che, nella dimensione della città media, possono trovare l’ambiente adatto e anche una giusta governance che sia vicina, attenta, collaborativa.
2018/09/19: The new Code of Conduct makes me feel threatened and uncomfortable.
No, really. As a person with (diagnosed) Asperger's, I'm a member of,
objectively, a marginalised minority. Effectively (i.e. this is a massive
oversimplification), I was born without the hard-wired circuitry for
social interactions that is normally a part of the human brain; consequently
I have to run a slow and inaccurate software simulation when interacting with
2018/09/16: our public school systems are barely providing basic literacy: about 1 in 7 American adults would struggle to read a children’s book. In higher ed, students last year graduated with an average of $39,400 in debt. The top 1 percent of American households today controls more wealth than the bottom 90 percent combined. Our justice system puts African Americans in prison at five times the rate of whites.
And voting suppression and intimidation is everywhere — purges to voting rolls in Indiana, Texas repeatedly found guilty of discriminatory practices, gerrymandering everywhere turning Democratic votes meaningless. And Republicans are trying to pass a constitutional amendment that would require voters show a state-issued photo ID at the polls, which research, as well as common sense, tells us suppresses minority votes.
Do you ever stop and marvel how everything seems to be in crisis all at once? Or, as an African-American friend said to me recently, now everyone in America has a glimpse of what it’s like to be black.
It’s not a coincidence, of course. In the system of democratic society, all the parts are totally interdependent.
In the first two parts of this series, we discussed the hardware and software fundamentals for building network-attached storage (NAS) on a Raspberry Pi. We also put a proper backup strategy in place to secure the data on the NAS. In this third part, we will talk about a convenient way to store, access, and share your data with Nextcloud.
2018/9/18: For years, Facebook has publicly positioned its Messenger application as a way to connect with friends and as a way to help customers interact directly with businesses. But a new report from The Wall Street Journal today indicates that Facebook also saw its Messenger platform as a siphon for the sensitive financial data of its users, information it would not otherwise have access to unless a customer interacted with, say, a banking institution over chat. In this case, the WSJ report says not only did the banks find Facebook's methods obtrusive, but the companies also pushed back against the social network and, in some cases, moved conversations off Messenger to avoid handing Facebook any sensitive data. Among the financial firms Facebook is said to have argued with about customer data are American Express, Bank of America, and Wells Fargo.
The report says Facebook was interested in helping banks create bots for its Messenger platform, as part of a big push in 2016 to turn the chat app into an automated hub of digital life that could help you solve problems and avoid cumbersome customer service calls. But some of these bots, like the one American Express developed for Messenger last year, deliberately avoided sending transaction information over the platform after Facebook made clear it wanted to use customer spending habits as part of its ad targeting business. In some cases, companies like PayPal and Western Union negotiated special contracts that would let them offer many detailed and useful services like money transfers, the WSJ reports. But by and large, big banks in the U.S. have reportedly shied away from working with Facebook due to how aggressively it pushed for access to customer data.

Health misinformation in Nigeria varies from “cruel hoaxes” such as drinking saltwater to cure Ebola, to general misperceptions about causes of disease, mode of transmission and available treatment.
There are also ungrounded concerns about the safety of medical interventions. Classic examples include false beliefs about contraceptives and vaccinations.
Nigerians have "generally poor health-seeking behaviour" as a a result of poverty, religion and a poorly functioning health system. Social media makes the situation worse by spreading false health rumours.
2018/09/18: Kosovo is currently facing severe economic challenges. It is one of the poorest countries in Europe, and its unemployment rate has reached as high as 30%. Studies show that up to 57.7% of young people are unable to find a job. (In an extreme case, some 300 Kosovars went overseas to join ISIS.) According to a 2016 survey, up to half of Kosovars wish to ‘go westward’ and emigrate to countries in Western Europe.
From this backdrop spawned Open Data Kosovo, a civic technology organization which believes that the push for reform must continue after independence for a ‘good country’ to truly be born. “People are expected to follow the new constitution, but they don’t criticize what [this new country] lacks,” said Blerta Thaci, CEO of Open Data Kosovo. “In consequence, changing the status quo is but our own duty.”
2018/09/12: after a new report revealing a more than 25% rise in U.S. suicides since 2000, some called for new antidepressants, but that only buys into the mainstream notion that "mental illness" is primarily physiological in nature, caused by a "broken" brain.
we must move beyond a focus on the individual and think of well-being as a social issue.
economic inequality could be a significant contributor to mental illness.
2018/09/18: The board can be used as a general purpose I/O and DAQ add-on but is specifically designed as a control board for aquaponics and hydroponics gardening.
2018/09/12: Article 12a: No posting your own photos or videos of sports matches. Only the “organisers” of sports matches will have the right to publicly post any kind of record of the match. No posting your selfies, or short videos of exciting plays. You are the audience, your job is to sit where you’re told, passively watch the game and go home.
At the same time, the EU rejected even the most modest proposals to make copyright suited to the twenty-first century:
1. No “freedom of panorama.” When we take photos or videos in public spaces, we’re apt to incidentally capture copyrighted works: from stock art in ads on the sides of buses to t-shirts worn by protestors, to building facades claimed by architects as their copyright. The EU rejected a proposal that would make it legal Europe-wide to photograph street scenes without worrying about infringing the copyright of objects in the background.
2018/09/16: non c’è nulla di meglio della incedibile vicenda della Bekaert - dunque - per spiegare i motivi della rottura fra il centrosinistra e la sua base elettorale.
2018/09/14: Con New York abbiamo un laboratorio congiunto di innovazione civica e urbana. Con Berlino lavoriamo sulle politiche abitative e su come regolare le piattaforme della sharing economy, con Parigi sui Fab Labs e l’economia circolare, con Amsterdam abbiamo forti affinità e progetti congiunti come DECODE. In Italia collaboriamo con Milano, Roma e Torino sulle politiche dei dati, sulle piattaforme digitali per la partecipazione democratica e sul software libero. Le altre città vedono Barcellona come modello di una politica innovativa e allo stesso tempo democratica. Abbiamo lavorato anche con il team digitale del governo inglese, che già da alcuni anni ha realizzato una digitalizzazione di successo, e quello estone, che è stato il primo a creare un’identità pubblica digitale. E nel contesto europeo coordino una rete di Chief Innovation Officers (CIOs) che si scambiano policy e soluzioni concrete per valorizzare le opportunità e ridurre i rischi del digitale. È fondamentale sperimentare e replicare strategie e progetti, partendo dalle città come laboratorio del futuro digitale che vogliamo, più inclusivo e democratico.
The narrative that government is inefficient and its optimum role should be "limited" to avoid disrupting the market has proven extremely powerful. But this prevailing view of government is wrong; it is more the product of ideological bias than anything else.
