   Early electronic computers such as Colossus made use of punched tape, a long strip of paper on which data was represented by a series of holes, a technology now obsolete. Electronic data storage, which is used in modern computers, dates from World War II, when a form of delay-line memory was developed to remove the clutter from radar signals, the first practical application of which was the mercury delay line. The first random-access digital storage device was the Williams tube, based on a standard cathode ray tube, but the information stored in it was volatile in that it had to be continuously refreshed, and thus was lost once power was removed. The earliest form of nonvolatile computer storage was the magnetic drum, invented in 1932 and used in the Ferranti Mark 1, the world’s first commercially available general-purpose electronic computer.

   Jack Kilby’s revolutionary idea was to make all the different components of a circuit out of the same flat block of semiconductor material. Not only would this get rid of wires and faulty connections, it would make the entire circuit much more compact. Kilby demonstrated his first “integrated circuit” on Sept. 12, 1958.
   Six months later, in California, another engineer, Robert Noyce, independently came up with the idea of making an integrated circuit. Noyce’s chip was better suited to be manufactured in large numbers, and soon he was part of a young company called Intel.
   Thus was launched a revolution. The first chip-based computer was the first U.S. Air Force computer, built in 1961. The true potential of the integrated circuit was shown when Texas Instruments unveiled the pocket calculator. Previously calculators had been bulky devices that needed to be plugged in to electrical mains. The pocket calculator, small enough to hold in one’s palm, had a chip inside and batteries were adequate to power it.
   Progress was rapid thereafter. Many have already heard of Moore’s law, which has become a mantra of the digital age. First put forward by the Intel co-founder Gordon Moore in the 1960s, it says that the processing power of a chip doubles every two years, while the price falls by half. For more than four decades, Moore’s law has held, driving incredible growth and miniaturization — and wealth.
  The question is whether the semiconductor industry can sustain this pace. Further increasing the processing power of chips is proving to be problematic as certain fundamental physical barriers are being reached. At the same time, new frontiers are opening up. The quest is on to make chips that are powered by light instead of electricity, which will enable much faster computers.

Q1877926 Inglês
   In May 2021, a hole was found in a robotic arm aboard the International Space Station (ISS). The suspected culprit was a piece of rogue space junk. While thankfully no astronauts were injured, it has re-focussed attention on the growing problem of orbital debris.

How did we get here?
   It’s easy to forget that just seven decades ago the Moon was the only thing orbiting the Earth. On 1 January 2021 there were 6,542 satellites in orbit. Tellingly, only just over half of them were active. That’s a lot of useless metal careering around the planet at 28,000 kph — ten times faster than a bullet.

How bad is the problem?
   Very bad and getting worse. Estimates suggest there are currently half a million pieces of debris the size of a marble or larger and 100 million pieces of debris above one millimeter across. Yet only 27,000 pieces are actively tracked by the US Department of Defense.

What is Kessler syndrome?
   It’s a catastrophic chain of events in which a satellite is shattered by a piece of space junk (or a collision with another satellite) and the resulting debris destroys more satellites creating more junk and so on in a never-ending cascade. It’s a domino effect – one piece falls and then takes the rest with it – and is named after NASA scientist Donald Kessler, who outlined the dangers back in 1978.

What can we do about it?
   Better regulation of new launches would help, as right now it’s a bit of a free-for-all. There are existing regulations in place to try and mitigate the dangers, such as a 25-year de-orbit rule for missions in low-Earth orbit. However, ESA’s Space Debris Environment Report says that less than 60 per cent of those flying in low-Earth orbit currently stick to the rules.

   The European Environment Agency (EEA) has published a new indicator that tracks findings of pesticides in Europe’s rivers, lakes and groundwaters. The data, collected from EEA member countries across Europe, shows the share of water bodies where excessive levels of pesticides have been recorded from 2013 to 2019. 
  The new EEA indicator shows that levels of pesticides exceeding thresholds were measured in a quarter of all reported monitoring sites in European surface waters in 2019. From 2013 to 2019, this share varied between 13% and 30%. The share for groundwater with exceedances was considerably lower, at between 3% and 7%.  
   In the EU, pesticides are regulated on the basis of high protection goals for human health and the environment, with being authorised only after a comprehensive scientific risk assessment. Nevertheless, pesticide contamination of surface waters and groundwater can still occur and could affect aquatic fauna and flora.

    There’s growing evidence that people and the planet are increasingly impacted by extreme events. According to the Fourth National Climate Assessment, published in 2018 by the U.S. Global Change Research Program, “more frequent and intense extreme weather and climate-related events, as well as changes in average climate conditions, are expected to continue to damage infrastructure, ecosystems, and social systems that provide essential benefits to communities.”
      As the impacts of extreme events continue to mount, interest has grown in the scientific community to study whether specific extreme events can be partially attributed to human activities. With the help of climate models, scientists have conducted an impressive array of studies, looking for possible links between human activities and extreme events such as heat waves, rainfall and flooding events, droughts, storms, and wildfires. Increasingly, they’re able to draw robust connections.

Phishing

Imagine that you get an email one morning. It appears to be from your bank. The email warns that someone broke into your account. It says that you need to sign in to check some things. You click the link in the email. It takes you to a site that looks very much like your bank’s. You enter your username and password. You submit the form. You’ve just been phished!

Phishing is a type of attack that happens over the Internet. Users receive an email or text message that seems like it came from a trusted source. These users are being deceived. They are interacting with dangerous hackers. The attackers copy trusted companies. They send users to web pages that look like the ones we use everyday. When users login or provide sensitive information, the attackers steal this data.

Attackers want your data for many reasons. They may use your data to commit identity fraud. This is when they use your identity to buy something with your credit. Then they receive the goods and you receive the bill. Or they may want your password to take over a computer network. They may want access to private emails. They may want customer records. They gain access by tricking people into giving them their login info.

Some phishing attacks are targeted. A targeted phishing attack is called a spear phishing attack. These attacks are dangerous because they are convincing. The attacker may know the target’s name, address, or job title. They may have gathered info from social networks, like the names of friends or family. The attackers may use this personal information to craft a believable email. The target will be tricked into clicking a link. The link will send them to a phony website. This site will look familiar, but it will be a spoofed site built to steal data. Any data that the target submits will go to the hacker.

Phishing attacks are dangerous, but you can spot them if you pay attention. One thing to watch is your address bar in your browser. Attackers use domains that look like the ones that we trust, but they are not the same. For example, in 2016 staffers from Hillary Clinton’s campaign were spear phished. The attackers used the domain accounts-google.com. That domain looks like google.com, but it isn’t the same. When logging into google, you should always do it from google.com. Likewise, when logging into any account, make sure the address matches what you expect. If you are unsure, search for the site and login from the root domain.

An even better way to secure your account against phishing attacks is to use 2FA: two factor authentication. 2FA means that your account is secured with two keys. The first is your password. The second key is a random code that changes every few minutes. This code may be generated by a 2FA app, like Authy. Or it can be sent to your cell phone on request. If you activate 2FA on your accounts, an attacker will not be able to get in even with your password.

Phishing attacks are scary and common. The reason why they are common is that they are effective. Many people accept appearances without suspicion. Browsing the Internet safely requires a healthy amount of suspicion. Not everything is what it appears. Nobody is trying to give you free money. Don’t trust; verify.

Phishing is a type of attack that happens over the Internet. Users receive an email or text message that seems like it came from a trusted source. These users are being deceived. They are interacting with dangerous hackers. The attackers copy trusted companies. They send users to web pages that look like the ones we use everyday. When users login or provide sensitive information, the attackers steal this data.

Attackers want your data for many reasons. They may use your data to commit identity fraud. This is when they use your identity to buy something with your credit. Then they receive the goods and you receive the bill. Or they may want your password to take over a computer network. They may want access to private emails. They may want customer records. They gain access by tricking people into giving them their login info.

Some phishing attacks are targeted. A targeted phishing attack is called a spear phishing attack. These attacks are dangerous because they are convincing. The attacker may know the target’s name, address, or job title. They may have gathered info from social networks, like the names of friends or family. The attackers may use this personal information to craft a believable email. The target will be tricked into clicking a link. The link will send them to a phony website. This site will look familiar, but it will be a spoofed site built to steal data. Any data that the target submits will go to the hacker.

Phishing attacks are dangerous, but you can spot them if you pay attention. One thing to watch is your address bar in your browser. Attackers use domains that look like the ones that we trust, but they are not the same. For example, in 2016 staffers from Hillary Clinton’s campaign were spear phished. The attackers used the domain accounts-google.com. That domain looks like google.com, but it isn’t the same. When logging into google, you should always do it from google.com. Likewise, when logging into any account, make sure the address matches what you expect. If you are unsure, search for the site and login from the root domain.

An even better way to secure your account against phishing attacks is to use 2FA: two factor authentication. 2FA means that your account is secured with two keys. The first is your password. The second key is a random code that changes every few minutes. This code may be generated by a 2FA app, like Authy. Or it can be sent to your cell phone on request. If you activate 2FA on your accounts, an attacker will not be able to get in even with your password.

Phishing attacks are scary and common. The reason why they are common is that they are effective. Many people accept appearances without suspicion. Browsing the Internet safely requires a healthy amount of suspicion. Not everything is what it appears. Nobody is trying to give you free money. Don’t trust; verify.

“He remembered the time he had hooked one of a pair of marlin. The male fish always let the female fish feed first and the hooked fish, the female, made a wild, panic-stricken, despairing fight that soon exhausted her, and all the time the male had stayed with her, crossing the line and circling with her on the surface.

He had stayed so close that the old man was afraid he would cut the line with his tail which was sharp as a scythe and almost of that size and shape. When the old man had gaffed her and clubbed her, holding the rapier bill with its sandpaper edge and clubbing her across the top of her head until her colour turned to a colour almost like the backing of mirrors, and then, with the boy’s aid, hoisted her aboard, the male fish had stayed by the side of the boat.

Then, while the old man was clearing the lines and preparing the harpoon, the male fish jumped high into the air beside the boat to see where the female was and then went down deep, his lavender wings, that were his pectoral fins, spread wide and all his wide lavender stripes showing. He was beautiful, the old man remembered, and he had stayed.”
