After WhatsApp announced the update of its policies to share data with Facebook , millions of users migrated to other messaging apps . The two favorites have been Telegram and Signal , apparently for offering greater privacy. However, none of the three is completely reliable, unless you change certain security settings to better protect your information .
Cybersecurity expert Zak Doffman claims that Telegram and Signal promise more privacy than traditional platforms. However, like WhatsApp , they have important settings that are not predetermined and that must be modified from now on.
Now that these platforms are gaining popularity, the specialist shared his recommendations to configure the devices so that our data is less accessible.
WhatsApp
In this app, messages are encrypted end-to-end and only users have access to the content. However, Doffman says that “the problem is the metadata : who, when and where in relation to your messages , as well as your contacts and information about your device . ”
“WhatApp can still be used […] However, it is necessary to change this fundamental configuration to stay safe,” said the specialist at Forbes .
Avoid malicious content you receive , such as unknown links and attachments.
Disables the option to automatically save received images in the phone gallery.
Obtain the PIN number that ‘two-step verification’ offers to prevent hackers from hijacking your account with deception.
Turn off backups. While the messages are protected as they are sent, “if you use the WhatsApp option to back up your chat history to the Apple or Google cloud, those copies are not protected by that end-to-end encryption. extreme, ” warned the cybersecurity expert.

“We want to address some rumors and be 100% clear, we continue to protect your private messages with end-to-end encryption,” WhatsApp noted on its official Twitter account a few days ago.
Telegram
As in WhatsApp and Signal , when you access Telegram for the first time on a device, you must enter a phone number. Then they ask you to write the confirmation message sent by SMS. The problem is that if someone steals that code “they can hijack your account and access your content,” Doffman pointed out in another article for Forbes .
To be safe on Telegram , the analyst recommends the following changes:
Activate ‘two-step verification’ (2FA). Go to the settings, enter the ‘privacy and security’ section, add a password and that’s it!
Change your privacy settings. In the ‘privacy’ section choose that only your contacts can communicate with you, and no one else. You can also limit who sees your profile, if your status (online) and last connection is shown, or who can add you to groups.
Use a ‘ lock code’. If other people besides you have access to your device, it is important to protect your chats.
Periodically review the active sessions in your account. This way you can make sure that no one has entered from another device.
Secret chats and end-to-end encryption. Telegram offers ‘secret chats’, which offer encryption from one device to another, but it doesn’t work for groups. To start a secret chat go to the normal chat with your contact, click on the three dots on Android or ‘more’ on iOS, and choose ‘start secret chat’.
Activate self-destruction. Another attraction of this app is that it has the option of destroying messages shortly after being viewed.
Signal
It has more or less the same advantages and limitations as Telegram, with the difference that Elon Musk himself recommended using Signal. Of course, this application is not risk-free either and it is also advisable to modify some settings:
Activate the ‘ registry lock’. This will prevent someone else from having access to your conversation history in case your account is stolen or hijacked.
Set the ‘screen lock’ using biometric security or a passcode.
Turn off previews. This way the messages will not appear on the main screen of the device.
Disable screenshots outside of the app.
Make it your default SMS messaging app. Doffman shared this trick for Android users, since by doing so the messaging will be more secure and encrypted, unlike the conventional one.
Final advice
Doffman explained that WhatsApp collects much more data than Telegram or iMessage , but   they are few compared to other apps , such as Facebook, Messenger, Google, Instagram, Snapchat and TikTok . “So unless you avoid those others, WhatsApp is not your biggest problem,” he added.
The expert warns that “there is a much bigger problem” , referring to Facebook’s plans to integrate WhatsApp with Messenger and Instagram . “The idea is to create a great interoperable messaging giant that brings together all its audiences,” he explained in the same publication. It added that that would be “much more serious” for user privacy than the recent update.

Risk areas are those whose incidence exceeds 50 new infections per 100,000 inhabitants in the last seven days. This currently applies to almost all of Europe, except some areas of Greece, Finland, Norway, Austria and Denmark. Travelers from these regions must undergo a coronavirus test within 48 hours of arrival and spend ten days in quarantine.
High-risk areas are those with significantly higher infection rates than Germany. As a general rule, these are countries with an incidence value higher than 200, since the incidence in Germany is 111. However, other countries below this mark can also be declared ‘high incidence areas’ under certain conditions .The virus variant zones are those where highly infectious strains of the SARS-CoV-2 virus have been detected, such as the United Kingdom, Ireland, South Africa and Brazil.

How The Philosophy Of Nintendo’s Game Boy Inventor Is Ripe For These Times

2020 was a record-breaking sales year for video-game makers as people turned to tech-fueled diversions during COVID-19 lockdowns.  Video game industry revenues in 2020 are estimated to exceed both sports and film combined, with experts forecasting strong growth well into 2021 fueled by new games and consoles, and an anticipated rush of gaming IPOs, such as Roblox. With the focus on shiny new releases and game changing technology, one might forget that one of the most popular and best-selling game consoles-the Nintendo Game Boy- was designed based on an entirely different philosophy: lateral thinking with withered technologies.  
Espoused by Nintendo game designer Gunpei Yokoi (no relation to author), the concept is to use cheap and readily available (withered) technology and combine it with creative (lateral) thinking to come up with innovative ways to engage users.  The Game Boy was considered an innovative product, but the LCD screens used were affordable and already widely prevalent. Instead of seeking out cutting-edge hardware features, the philosophy was to focus on novel game play using cheap and readily available technology. Yokoi’s philosophy is widely credited in guiding the development of Nintendo’s Game Boy, and informing the development of the Wii U and 3DS.
The philosophy of lateral thinking with withered technology is particularly relevant in these disruptive times which require rapid innovation and a sensitivity to sustainability. 
The philosophy is similar in spirit with the Maker Movement-an umbrella term for independent inventors, designers and tinkers, that has grown into a worldwide phenomenon in the past ten years. Makers tap into the spirit of self-reliance and Do-It-Yourself (DIY) to experiment and innovate using widespread technologies such as open-source software, 3D printing and robotics.  

The activities of the Maker community in response to COVID-19 demonstrates the potential of lateral thinking with withered technologies. Since the beginning of the COVID-19 pandemic, Makers mobilized to find various solutions ranging from face shields  to emergency ventilators by applying and combining existing technology in new ways, leveraging rapid prototyping and an agile manufacturing approach. Some observers consider this activity as a type of frugal innovation which could fill voids in fast and targeted ways to disrupt current incumbents. It could result in outcomes that are intrinsically sustainable due to the minimization of costs and resources.
But perhaps this philosophy and its potential uptake points to something deeper. 
Anthropologist Claude Levi Strauss used the word bricolage to describe a way of acting interacting with the environment as “doing things with whatever is at hand.”  Bricolage  was leveraged by organizational theorist, Karl Weick, in his analysis of the 1949 Mann Gulch disaster as a source of  resilience. Weick puts forth the idea that people who are skilled in improvisation and bricolage remain creative under pressure, because they’re accustomed to working in conditions where objectives and structures are unclear. Those who bricolage often work with whatever is at hand and can form them into new combinations and solutions.

This philosophy and its embodiment in the Maker Movement  could be a manifestation of our deeper desire for resilience. This way of using nonlinear, unplanned and indirect ways of thinking gives us confidence that we might be able act when faced with an unanticipated event. As Dave Dougherty, founder of the Maker Movement describes in an interview with pri.org, “It’s not about how good you are. It’s about the sense of control and the sense of purpose and of setting your own direction.”
