From putrid water to fizzy cola, food processing gave us preservation, consistency and innovation. So how did it become associated with unhealthy food?

Date Published: Wed, 9 Jun 2021 21:18:00 +0200

Much of food processing is about making foods safer and longer-lasting, which is better for the environment as it means less food waste. But clearly some processed foods are very bad for your health. Where did this happen?

The 4th Earl of Sandwich is perhaps best-known for lending his name to two slices of bread with a filling in between. However, he has another claim to a lunchtime staple – soft drinks (this I did not know).

"The problem is that, in the past half century, a different type of food processing has been developed," says Fernanda Rauber, a nutritional epidemiologist at the University of São Paulo, Brazil, about what we now call "“ultra-processed foods”. "These substances would not be found in our kitchen. Usually, they contain little to no proportion of real foods."

There are no antioxidants and phytochemicals that we find in whole foods if they are stripped out in processing." Even when nutrients are added back in, like cereals fortified with iron or fibre, food might not be as healthy as it seems. Added nutrients don’t work as well as those found in whole foods, she says.

Today, added sugar contributes to a lot of the health problems that people associate with processed foods (they account for more than 10% of people’s total calories). But it wasn’t always the case.

Quite an interesting read at How processed foods became so unhealthy

Bitcoin now legal tender in El Salvador, first nation to adopt cryptocurrency... What could possibly go wrong

Date Published: Wed, 9 Jun 2021 20:01:04 +0200

On Wednesday, El Salvador’s president signed into law a proposal to adopt Bitcoin as legal tender, making the Central American nation the first in the world to officially use the cryptocurrency.

The new law says that companies must accept Bitcoin as a form of payment, and the government will allow people to pay taxes with it as well. The exchange rate with the dollar will be set by the market, and exchanges from dollars to Bitcoin won’t be subject to capital gains tax. The law was passed by a super majority vote of the legislature, with 62 of 84 deputies assenting.
President Nayib Bukele said the new law would make it easier for Salvadorans living abroad to send remittances back to friends and family in the country.

Well it is very forward-thinking, and adopting a cryptocurrency in theory is fine (other banks are also looking at it), but Bitcoin itself is quite volatile, and generally a country wants predictability around its currency. An advantage for remittances I suppose it not having to make use of expensive international banking transfer systems.

What is Ultra Wideband and why it is good for location services?

Date Published: Wed, 9 Jun 2021 19:00:48 +0200

If you’ve been following the world of mobile phone technology of late, you may be aware that Apple’s latest IPhones and AirTag locator tags bring something new to that platform. Ultra wideband radios are the new hotness when it comes to cellphones, so just what are they, and what’s in it for those of us who experiment with these things?

The real trick up the sleeve for UWB comes not in its data transfer capabilities but in location services, because it allows the synthesis of extremely short RF pulses on the order of a fraction of a nanosecond by combining frequencies across that wide bandwidth. These pulses can be used for extremely accurate time-of-flight measurements between transmitter and receiver, allowing for the distance between them to be determined to an accuracy of a few centimeters. In a system such as Apple AirTags where a tag is likely to have visibility to more than one UWB-equipped Apple product, it can then be used for triangulation with several sources, and thus for accurate 2D and 3D positioning.

How to use a hardware two-factor security key - Two-factor authentication is a good way to add an extra layer of security to online accounts

Date Published: Wed, 9 Jun 2021 16:54:52 +0200

It requires the use of your smartphone, however, which is not only inconvenient, but can be a problem if your phone is lost or breached. Hardware security keys can offer an additional layer of security to password-protected online accounts and, in turn, your identity. They’re also not hard to install. Here’s how to set them up for your Google account, Facebook, and Twitter.

When you insert a security key into your computer or connect one wirelessly, your browser issues a challenge to the key, which includes the domain name of the specific site you are trying to access. The key then cryptographically signs and allows the challenge, logging you in to the service.

Many sites support U2F security keys, including Twitter, Facebook, Google, Instagram, GitHub, Dropbox, Electronic Arts, Epic Games, Microsoft account services, Nintendo, Okta, Reddit, and many more.

9 Positives That Can Happen to Your Body If You Start Eating 2 Eggs Daily

Date Published: Tue, 8 Jun 2021 13:29:13 +0200

Seven grams of protein and 85 calories is not the only benefit you reap from chicken eggs. You also get antioxidants, healthy fats, and amino acids. The York also contains choline, a fat-fighting nutrient. Contrary to what you may have heard, the cholesterol in eggs will not make you fat or increase your bad cholesterol (that myth is now dead I hope).

The American Journal of Clinical Nutrition found that men (we hope women too) who had one egg a day performed better in cognitive tests than those who didn’t. Harvard Health confirms this by describing eggs as brain food that protects the brain from decline as you age. Mom’s are also encouraged to give babies one egg a day to boost their brain development and function. Choline from the eggs also provides the babies with required nutrients for memory and muscle control.

These are the Best Mechanical Keyboards to buy: Corsair, Logitech, Razer, and more

Date Published: Tue, 8 Jun 2021 13:12:50 +0200

Why should you buy a Mechanical Keyboard? Cheaper keyboards usually incorporate a rubber-dome or a membrane switch system wherein a keypress pushes onto a silicone dome, connecting the circuit to register what the user is typing. These often require a large amount of force for actuation and give off mushy feedback due to the silicon underneath. These are relatively silent and don’t offer audible feedback, while the overall lifespan of the keys is also comparatively shorter.

When you press a key on a mechanical keyboard, an actual physical switch, including a spring-based pushback mechanism, comes into play. Depending on the type of key switch, you get a certain tactile or linear feedback as you type along. While that in itself makes a huge difference, these switches also last really long, with certain manufacturers claiming up to 50-80 million keystrokes.

In short, mechanical keyboards offer a longer shelf life, and you can expect a much better typing experience thanks to the wide variety of switch options.

Glad to see Redragon getting a mention as I've been using mine for a few years without any issues.

New Separation Alerts in iOS 15 Let You Know If You Leave an AirTag or Apple Device Behind (a bit like how Android Tasker app works)

Date Published: Tue, 8 Jun 2021 12:12:07 +0200

This is something I've been looking for on iOS for a while now. It fits the scenario where you are sitting in a restaurant using your mobile hotspot and then leave it behind. Android's Tasker app would do this for any Bluetooth or WiFi connected device.

In that way AirTag separation alerts would be better as they can be attached to anything, not just working with WiFi or Bluetooth lost connections. I'm still surprised that Apple Shortcuts did not provide this simple functionality. But AirTag separation alerts can now potentially work for your keys, bag, your kids, etc that are AirTagged.

A simple but really quite essential functionality for early warning.

Apple in iOS 15 is adding new Separation Alerts to the Find My app, which will let you know if you leave an Apple device, a device attached to an AirTag, or a Find My-enabled third-party device behind.

Australian cops, FBI created backdoored chat app called ANOM, told crims it was secure — then listened to 9,000 users' plots

Date Published: Tue, 8 Jun 2021 10:17:22 +0200

Which is why many are suspicious of existing secure chat apps, and why the French government hosts its own server instance of Matrix, because you cannot even trust your allies.

This happened before of course in Switzerland with Crypto AG, the provider of secure encryption equipment to over 100 countries, which was owned by the US's CIA all the time. And ironically it is always what the Chinese are suspected of doing.

Busting criminals though of course is a good thing as long as innocent people are not being spied on (like one of Germany's Allies were caught doing on their Chancellor).

Apple’s new privacy feature will not be available in China – or South Africa, Belarus, Colombia, Egypt, Kazakhstan, Saudi Arabia, Turkmenistan, Uganda and the Philippines

Date Published: Tue, 8 Jun 2021 10:01:33 +0200

It's pretty revealing nowadays which governments are for the privacy of their citizens versus those who want to watch their citizens (the very people who voted them in and whom they represent). I'm strongly suspecting this is not the full list at all as I'm aware of another government who has a censorship list of blocked sites their citizens may not visit, and they don't appear here yet.

Apple's Facetime is coming to the devices via weblinks and not native apps, and still no RCS announced for iMessage

Date Published: Mon, 7 Jun 2021 21:22:15 +0200

For me, I only consider using an app if it is cross-platform, especially if it is a communications app. So Facetime will send links to
Android and Windows users now (really links don't work on Linux???) so that these users can join Facetime calls. But the point is Android and Windows (and Linux?) users cannot initiate Facetime calls to their friends. This basically cripples Facetime usage for most who have friends, colleagues and clients that don't all use iOS.

I was also hoping for RCS to be included in iMessage (again for cross-platform modern messaging across Android, iOS and other devices). It may be though that with RCS fully adopted that could cripple WhatsApp and similar messengers (well Apple has made major swipes already at Facebook, so I'm sure they'd not back away from taking a swipe at WhatsApp).

Other items of interest to me from Apple's WWDC 2021 were:
* Existing iCloud services will, at no extra cost, get a VPN service (Private Relay) and private e-mail (basically unlimited extra iCloud mail addresses which forward mail to your primary address).
* Digital identification to start for certain airports and US States but like Apple Pay should hopefully spread elsewhere soon.
* The Health app will more easily identify trends and changes over time, including mobility tracking and capturing a new walking
Steadiness Metric to assess your fall risk. Also seems like they will not just capture your cholesterol (and other) scores, but go a step further now to help interpret what the changes mean.
