Low-Dose Aspirin Late in Life? Healthy People May Not Need It

September 30, 2019

QT:{{”
“The most widely used guidelines for using aspirin to prevent disease came out in 2016 from experts at the United States Preventive Services Task Force. They recommend the drug to prevent cardiovascular disease and colorectal cancer in many people aged 50 to 59 who have more than a 10 percent risk of having a heart attack or stroke during the next 10 years. (That risk, based on age, blood pressure, cholesterol and others factors, can be estimated with an online calculator from the American Heart Association and the American College of Cardiology.)

For people 60 to 69 with the same risk level, the guidelines say it should be an individual decision whether to take aspirin.

But for people 70 and over, the guidelines say there’s not enough evidence to make any recommendation.”

“How: A browser extension like uBlock Origin blocks ads and the data they collect. The uBlock Origin extension also prevents malware from running in your browser and gives you an easy way to turn the ad blocking off when you want to support sites you know are secure. Combine uBlock with Privacy Badger, which blocks trackers, and ads won’t follow you around as much. To slow down stalker ads even more, disable interest-based ads from Apple, Facebook, Google and Twitter. A lot of websites offer means to opt out of data collection, but you need to do so manually. Simple Opt Out has direct links to opt-out instructions for major sites like Netflix, Reddit and more. Doing this won’t eliminate the problem completely, but it will significantly cut down on the amount of data collected.

You should also install the HTTPS Everywhere extension. HTTPS Everywhere automatically directs you to the secure version of a site when the site supports that, making it difficult for an attacker — especially if you’re on public Wi-Fi at a coffee shop, airport or hotel — to digitally eavesdrop on what you’re doing.

Some people may want to use a virtual private network (VPN), but it’s not necessary for everyone. If you frequently connect to public Wi-Fi, a VPN is useful because it adds a layer of security to your browsing when HTTPS isn’t available. It can also provide some privacy from your internet service provider and help minimize tracking based on your IP address. But all your internet activity still flows through the VPN provider’s servers, so in using a VPN you’re choosing to trust that company over your ISP not to store or sell your data. Make sure you understand the pros and cons first, but if you want a VPN, Wirecutter recommends IVPN.”

How to stop data centres from gobbling up the world’s electricity

September 29, 2019

QT:{{”

“The savings made by hyperscale centres can be seen in their power usage efficiency (PUE), defined as the total energy needed for everything, including lights and cooling, divided by the energy used for computing (a PUE of 1.0 would be a perfect score). Conventional data centres typically have a PUE of about 2.0; for hyperscale facilities, that’s been whittled down to about 1.2. Google, for one, boasts a PUE of 1.12 on average for all its centres.

Older or less technologically adept data centres can contain a mix of equipment that is hard to optimize — and some that is even useless. In 2017, Jonathan Koomey, a California-based consultant and leading international expert on IT, surveyed with a colleague more than 16,000 servers tucked into corporate closets and basements and found that about one-quarter of them were “zombies”, sucking up power without doing any useful work — perhaps because someone simply forgot to turn them off. “These are servers sitting around doing nothing except using electricity, and that’s outrageous,” says Koomey.”
