    1. This is valid javascript! Or harmony or es6 or whatever, but importantly, it's not happening outside the js environment. This also allows us to use our standard tooling: the traceur compiler knows how to turn jsx`<div>Hello</div>`; into the equivalent browser compatible es3, and hence we can use anything the traceur compile accepts!
    1. The Digipo toolkit

      Perhaps I'm missing it, but is this not an open browser extension already? I'd love to have these pieces built as a WordPress or separate plugin. I've seen some of the pieces earlier today that look like they've been unbundled, but I'd love to have the rest...

    2. the event in Miami on Inauguration Day (site:www.sourcewatch.com OR site:www.factcheck.org OR site:hoax-slayer.com OR site:www.truthorfiction.com OR site:opensecrets.org OR site:www.politifact.com OR site:snopes.com OR site:www.washingtonpost.com/news/fact-checker/ OR site:digipo.io)

      just this piece makes this a powerful little tool!

    1. One key advantage of 'HTML-plus' languages is that you don't actually need tooling in order to be productive — most editors give you out-of-the-box support for things like syntax highlighting (though imperfect, as JavaScript expressions are treated as strings) and auto-closing tags. Tools like Emmet work with no additional setup. HTMLx should retain that benefit.

    1. por transferir sus plataformas operativas hacia los llamados softwares libres como OpenOffice o el tradicional Linux, las cuales podrían alcanzar efectivamente niveles aceptables de funcionalidad, pero incrementar el riesgo de fallas al carecer éstas de algún tipo de garantía.

      Linux, LibreOffice y en general el software libre y de código abierto sí tiene garantía. De hecho el modelo de negocio del software libre es ofrecer varios servicios, como soporte, capacitación, acompañamiento, etc, en lugar de la venta de licencias.

      Hablar de riesgo incrementado de fallas al caracer de "algún tipo de garantía" es cuando menos ignorante y a lo sumo malintencionado.

      Sobre los servicios de soporte para Linux y Libre Office basta con hacer simples búsquedas en Internet:

      Ambos listados contienen al menos decenas, si no centenares de compañías y profesionales independientes con amplia distribución geográfica.

      Ahora bien, si se refiere a la cláusula "NO WARRANTY" o "AS IS" habitual en todos los productos de software, tanto libres como privativos, que libera a desarrolladores de daños derivados del uso de su software, esta es una cláusula que aparece también en productos de grandes oligopolios digitales (Apple, Microsoft, Google, Amazon). Tanto así que hacer parte de los estándares contractuales.

    1. Chemically, europium’s reactions are similar to calcium. It is used in some superconductor alloys and in television screens, where it produces the red color.

      europium has been popularly used for the red flash and light in smart phones.

    1. Europium is used in the printing of euro banknotes. It glows red under UV light, and forgeries can be detected by the lack of this red glow.

      When they scan a bill they are looking for the europium flash.

    2. In 1901, Eugène-Anatole Demarçay carried out a painstaking sequence of crystallisations of samarium magnesium nitrate, and separated yet another new element: europium.
    3. Low-energy light bulbs contain a little europium to give a more natural light, by balancing the blue (cold) light with a little red (warm) light.
    4. A soft, silvery metal that tarnishes quickly and reacts with water.
    1. White phosphorus is a waxy, transparent solid. Its melting point is 44.1°C (111°F) and its boiling point is 280°C (536°F). It has a density of 1.88 grams per cubic centimeter. If kept in a vacuum, it sublimes if exposed to light.

      the properties of Phosphorus.

    1. somewhere at the interfaces between the solder balls and the nickel-phosphorous pad. Solders are ductile tin-based materials, but during soldering they chemically react with the solid metals being soldered — such as the nickel-phosphorous alloy — to form intermetallic compounds.

      How Phosphorus is used in a smartphone.

    1. Alloys[edit] Antimony forms a highly useful alloy with lead, increasing its hardness and mechanical strength. For most applications involving lead, varying amounts of antimony are used as alloying metal. In lead–acid batteries, this addition improves plate strength and charging characteristics.[49][59] For sailboats, lead keels are used as counterweights, ranging from 600 lbs to over 8000 lbs; to improve hardness and tensile strength of the lead keel, antimony is mixed with lead between 2% and 5% by volume. Antimony is used in antifriction alloys (such as Babbitt metal),[60] in bullets and lead shot, electrical cable sheathing, type metal (for example, for linotype printing machines[61]), solder (some "lead-free" solders contain 5% Sb),[62] in pewter,[63] and in hardening alloys with low tin content in the manufacturing of organ pipes. Other applications[edit] Three other applications consume nearly all the rest of the world's supply.[48] One application is as a stabilizer and catalyst for the production of polyethylene terephthalate.[48] Another is as a fining agent to remove microscopic bubbles in glass, mostly for TV screens;[64] antimony ions interact with oxygen, suppressing the tendency of the latter to form bubbles.[65] The third application is pigments.[48] Antimony is increasingly being used in semiconductors as a dopant in n-type silicon wafers[66] for diodes, infrared detectors, and Hall-effect devices. In the 1950s, the emitters and collectors of n-p-n alloy junction transistors were doped with tiny beads of a lead-antimony alloy.[67] Indium antimonide is used as a material for mid-infrared detectors.[68][69][70]

      Potential uses in phone batteries and silicon wafers As semi conductors.

    1. this will eventually lead to increasing concentrations in humans, animals and soil particles.

      blood clots could be made in a human or animal.

    1. Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.

      lead is radioactive, so when you touch it, it can effect your body.

    1. Crushed minerals are extracted with hydrochloric acid or sulfuric acid, which converts the insoluble oxides into soluble chlorides or sulfates. The acidic filtrates are partially neutralized with caustic soda to pH 3–4. Thorium precipitates as its hydroxide, and is then removed. The remaining solution is treated with ammonium oxalate to convert rare earths into their insoluble oxalates. The oxalates are converted to oxides by heating. The oxides are dissolved in nitric acid that excludes one of the main components, cerium, whose oxide is insoluble in HNO3. The solution is treated with magnesium nitrate to produce a crystallized mixture of double salts of gadolinium, samarium and europium. The salts are separated by ion exchange chromatography. The rare-earth ions are then selectively washed out by a suitable complexing agent.[
    1. Most of the antimony mined each year comes from China, which supplies over three-quarters of the world’s total. The remainder is from Russia, South Africa, Tajikistan, Bolivia, and a few other countries, including the United States. Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia.

      Top antimony producing countries

    1. Antimony is rarely found in its native (as an element) state. Instead, it usually occurs as a compound. The most common minerals of antimony are stibnite, tetrahedrite, bournonite, boulangerite, and jamesonite.

      How antimony is found in nature

    2. Antimony is a moderately active element. It does not combine with oxygen in the air at room temperature. It also does not react with cold water or with most cold acids. It does dissolve in some hot acids, however, and in aqua regia. Aqua regia is a mixture of hydrochloric and nitric acids. It often reacts with materials that do not react with either acid separately.

      Chemical properties of antimony

    3. Antimony is a silvery-white, shiny element that looks like a metal. It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F). It is a relatively soft material that can be scratched by glass. Its density is 6.68 grams per cubic centimeter.

      Physical properties of antimony

    1. Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans.

      Negative health effects of repeated exposure to antimony

    1. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength. A lead-antimony alloy is used in batteries. Other uses of antimony alloys include type metal (in printing presses), bullets and cable sheathing. Antimony compounds are used to make flame-retardant materials, paints, enamels, glass and pottery.

      Uses of antimony in technology

    1. europium are crucial to your iPhone’s function – they’re used in the phone’s battery, as well as to help give the display screen colour and make the phone vibrate when you get a text,

      Needed for normal function in Iphone.

    1. Lanthanum mainly is obtained from lanthanum-rich monazite and bastnasite. Other lanthanum-bearing minerals include allanite and cerite. It is mined in the USA, China, Russia, Australia, and India.

      This is where Lanthanum is mined and where it comes from in the mines

    1. a relatively poor conductor of electricity

      lead is a poor electricity conductor but good and used in phone batteries.

    1. Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques.

      So different kinds of mining use different tunnel systems, how do we decide which kind is best in each situation?

    1. Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices.

    1. A Timestamp parameter name, which is simply an identifier to access the trigger in code. A Schedule, which is a CRON expression that sets the interval for the timer.
    1. authorization level. By default, it's set to "Function", which requires a function-specific API key, but it can also be set to "Admin" to use a global "master" key, or "Anonymous" to indicate that no key is required. You can also change the authorization level through the function properties after creation. Since we specified "Function" when we created this function, we will need to supply the key when we send the HTTP request. You can send it as a query string parameter named code, or as an HTTP header (preferred) named x-functions-key.
    2. By default, functions have a timeout of 5 minutes. This timeout is configurable to a maximum of 10 minutes. If your function requires more than 10 minutes to execute, you can host it on a VM. Additionally, if your service is initiated through an HTTP request and you expect that value as an HTTP response, the timeout is further restricted to 2.5 minutes. Finally, there's also an option called Durable Functions that allows you to orchestrate the executions of multiple functions without any timeout.

    1. Social change hardly requires such self-flagellation by the ruling class. Similarly, black America needs no grand, magic End of Days in order to succeed. A compact program of on-the-ground policy changes could do vastly more than articulate yearnings for a hypothetical psychological revolution among whites that no one seriously imagines could ever happen in life as we know it.

    1. Gymnosperms

      There are currently only around 1000 gymnosperm species in existence, meanwhile there are 250,000-350,000 species of angiosperms.

    2. ginkgos

      Ginkgos are really neat looking. I also found it interesting that their English name and scientific name are the same. They are very hardy trees and can grow almost anywhere in the US.

    3. plants have tissues that conduct food and water

      These plant tissues (vascular tissues) are also known as "TRACHEOPHYTES". These Vascular tissues are made up of two main tissues - The Xylem and Phloem.

    4. oxygen from photosynthesis

      Plants do not always carry "breathe'' out oxygen - sometimes they produce CO2. This is mostly at night as they need to break down carbohydrates to produce energy and also there is no sunlight during the night. With sunlight being one of the main components in the Photosynthesis process, plants cannot produce oxygen at night.

    1. the government reported the discovery of large gold deposits in Lege Dimbi, also in Sidamo.

      This shows that there was gold in Ethiopia!

    1. Developing economies’ copper demand has steadily grown over the last decades, fueling economic and social improvement. By 2011, China already represented 40% of the demand.

      Why does China need so much.

    2. Codelco is a state-owned Chilean mining company and the world’s largest copper producer. Based on their annual report and USGS statistics, they produced ~10% of the world’s copper in 2015 and own 8% of global reserves. They are also a large producer of greenhouse gas emissions. Last year, Codelco produced 3,2 t CO2e/millions tmf from both indirect and direct effects, and in 2011 it consumed 12% of the total national electricity supply.

      Goddamn they should start recylcling

    3. Copper is a key driver of growth and economic wealth for Chile.
    1. Neodymium is chiefly obtained from monazite and bastnasite, where it occurs as an impurity. It is mined in the USA, China, Russia, Australia, and India.

      some info about the ore and where it is mined

    1. The Neodymium metal element is initially separated from refined Rare Earth oxides in an electrolytic furnace. The "Rare Earth" elements are lanthanoids (also called lanthanides) and the term arises from the uncommon oxide minerals used to isolate the elements

      how neodymium is refined

    1. Although few in number, the multinational mining companies that are earning billion-dollar profits in Zambia have had a massive impact on its environment and people.
    1. The metal is a solid material and metallic gray in color. Furthermore, the metal possess high melting and boiling points. At standard temperature and pressure, cobalt is not readily oxidized, which means it does not easily lose electrons from its surface.

      A description of cobalt.

    2. cobalt can be found among the d-block elements, transition metals. It has the chemical abbreviation Co and atomic number 27.

      Where to find cobalt on periodic table and cobalt's atomic number.

    1. Monseigneur de Hemptinne watched Yeke people working at Dikuluwe as late as 1924. They worked in the dry season and stopped when the first rains arrived. The mining camp was near a stream where millet could be planted. Women and children collected malachite from the surface, while men used iron picks to excavate pits and shafts, using fire to crack the rocks when needed. The mines were between 10 metres (33 ft) and 15 metres (49 ft) deep with galleries up to 20 metres (66 ft) long. The ore would be sorted and then taken to a nearby stream for concentration before being smelted

    1. Scott's

      It is interesting that Austen repeatedly references Sir Walter Scott here. Scott was a fan of Austen's work and repeatedly praised her in his journal.

      Scott wrote of Austen: "Also read again, and for the third time at least, Miss Austen’s very finely written novel of Pride and Prejudice. That young lady had a talent for describing the involvements and feelings and characters of ordinary life, which is to me the most wonderful I ever met with. The Big Bow-wow strain I can do myself like any now going; but the exquisite touch, which renders ordinary commonplace things and characters interesting, from the truth of the description and the sentiment, is denied to me. What a pity such a gifted creature died so early!"

    1. Being a teenager is hard; there are constant social and emotional pressures that have just been introduced into the life of a middle or high schooler, which combines with puberty to create a ticking time bomb. By looking at the constant exposure to unreasonable expectations smartphones and social media create, we can see that smartphones are leading to an increased level of depression and anxiety in teenagers, an important issue because we need to find a safe way to use smartphones for the furture generations that are growing up with them. Social media is a large part of a majority of young adults life, whether it includes Instagram, Facebook, Snapchat, Twitter, or some combination of these platforms, most kids have some sort of presence online. Sites like Facebook and Instagram provide friends with a snapshot of an event that happened in your life, and people tend to share the positive events online, but this creates a dangerous impact on the person scrolling.​ When teens spend hours scrolling through excluisvely happy posts, it creates an unrealistic expectation for how real life should be. Without context, teenagers often feel as if their own life is not measuring up to all of their happy friends, but real-life will never measure up to the perfect ones expressed online. Picture Picture Furthermore, social media sites create a way for teenagers to seek external validation from likes and comments, but when the reactions online are not perceived as enough it dramatically alters a young adults self-confidence. This leads to the issue of cyberbullying. There are no restrictions on what you can say online, sometimes even annonimously, so often people choose to send negative messages online. Bullying is not a new concept, but with online bullying, there is little to no escape as a smartphone can be with a teenager everywhere, and wherever the smartphone goes the bullying follows.This makes cyberbullying a very effective way to decrease a youth's mental health, in fact, cyberbullying triples the risk of suicide in adolescents, which is already the third leading cause of death for this age group.

    1. Instead, I would encourage the social platforms to include prominent features for filtering and flagging. They should work with journalists and social psychologists to invent a new visual grammar so that when content is fact-checked, debunked, corrected, or verified, those processes are transparent and available to anyone seeking to understand more about the origins of a story.

    1. Biohackers will soon be able to forgo these companies altogether with an all-in-one desktop genome printer: a device much like an inkjet printer that employs the letters AGTC — genetic base pairs — instead of the color model CMYK.A similar device already exists for institutional labs, called BioXp 3200, which sells for about $65,000. But at-home biohackers can start with DNA Playground from Amino Labs, an Easy Bake genetic oven that costs less than an iPad, or The Odin’s Crispr gene-editing kit for $159.

      The BioXP does not have the DNA synthesis functionality mentioned in the former paragraph as a workaround for buying fragments of DNA. Instead this system seems to assemble smaller synthesized sequences into larger ones. Neither the DNA playground nor the CRISPR gene editing kit allow the automated construction of DNA and also do not have the ability to synthesize DNA from a digital sequence.

    1. The habit is simple. When you feel strong emotion — happiness, anger, pride, vindication — and that emotion pushes you to share a “fact” with others, STOP. Above all, it’s these things that you must fact-check. Why? Because you’re already likely to check things you know are important to get right, and you’re predisposed to analyze things that put you an intellectual frame of mind. But things that make you angry or overjoyed, well… our record as humans are not good with these things. As an example, we might cite this tweet which recently crossed my Twitter feed: You don’t need to know that much of the background here to see the emotionally charged nature of this. President Trump had insulted Chuck Schumer, a Democratic Senator from New York, saying tears that Schumer shed during a statement about refugees were “fake tears”.  This tweet reminds us that that Senator Schumer’s great grandmother died at the hands of the Nazis, which could explain Schumer’s emotional connection to the issue of refugees. Or does it? Do we actually know that Schumer’s great-grandmother died at the hands of the Nazis? And if we are not sure this is true, should we really be retweeting it?

      Example of importance of fact-check. How to spy lies based on a truthful story.

    1. Check for previous work: Look around to see if someone else has already fact-checked the claim or provided a synthesis of research. Go upstream to the source: Go “upstream” to the source of the claim. Most web content is not original. Get to the original source to understand the trustworthiness of the information. Read laterally: Read laterally.[1] Once you get to the source of a claim, read what other people say about the source (publication, author, etc.). The truth is in the network. Circle back: If you get lost, or hit dead ends, or find yourself going down an increasingly confusing rabbit hole, back up and start over knowing what you know now. You’re likely to take a more informed path with different search terms and better decisions.
