Privacy Lesson Plans for students. Why online privacy matters — and how to protect yours. As the principal technologist at the American Civil Liberties Union, Christopher Soghoian (TED talk: How to avoid surveillance … with the phone in your pocket) spends much of his time thinking about privacy and surveillance and how individuals can protect themselves from spying.

Yahoo is deleting all content ever posted to Yahoo Groups. Yahoo Groups is shutting down after more than 18 years, and the Verizon-owned company is deleting all content from the site in mid-December.

Yahoo is deleting all content ever posted to Yahoo Groups

"Yahoo has made the decision to no longer allow users to upload content to the Yahoo Groups site," the company said in a notice to users. "Beginning October 28, you won't be able to upload any more content to the site, and as of December 14 all previously posted content on the site will be permanently removed. You'll have until that date to save anything you've uploaded. " The notice links to one Yahoo webpage that provides instructions for downloading photos and files from groups that you belong to before the cutoff date, but the process sounds laborious, as it requires clicking on each photo or file you want to download. The shutdown notice also links to a page that provides instructions for requesting a download of all your Yahoo data. TechCrunch fait désormais partie d’Verizon Media.

Mozilla today announced that its Enhanced Tracking Protection feature for Firefox, which launched in July (and became the default in September), has now blocked a total of more than 450 billion third-party tracking requests from the thousands of companies that try to track you as you browse the web.

Robots.txt files were invented 20+ years ago to help advise “robots,” mostly search engine web crawlers, which sections of a web site should be crawled and indexed for search.

Robots.txt meant for search engines don’t work well for web archives

Many sites use their robots.txt files to improve their SEO (search engine optimization) by excluding duplicate content like print versions of recipes, excluding search result pages, excluding large files from crawling to save on hosting costs, or “hiding” sensitive areas of the site like administrative pages. What is 5G? The Next-Gen Network Explained. It’s been nearly a decade in the making, but 5G is finally becoming a reality.

What is 5G? The Next-Gen Network Explained

Carriers started rolling out fixed 5G to select cities a few years ago, and mobile 5G has already made appearances in cities around the country, with a much more comprehensive rollout expected over the next few years. Yet, it may seem as though there are more questions about 5G than there are answers. Low-Band to mmWave: The Different Types of 5G and How They Work. What Is 5G, and How Fast Will It Be? Once again, you can’t escape the 5G hype at CES.

What Is 5G, and How Fast Will It Be?

It’s been building since CES 2018. Everyone—from Samsung and Intel to cellular carriers and smartphone companies—wants you to know how amazing 5G will be. Samsung called it “wireless fiber”, promising super-fast low latency internet everywhere. 5G is supposed to be faster than a typical home cable internet connection today…and it’s wireless, too. Everything You Need to Know About 5G. Today’s mobile users want faster data speeds and more reliable service.

Everything You Need to Know About 5G

The next generation of wireless networks—5G—promises to deliver that, and much more. With 5G, users should be able to download a high-definition film in under a second (a task that could take 10 minutes on 4G LTE). And wireless engineers say these networks will boost the development of other new technologies, too, such as autonomous vehicles, virtual reality, and the Internet of Things. If all goes well, telecommunications companies hope to debut the first commercial 5G networks in the early 2020s. 5G specs announced: 20Gbps download, 1ms latency, 1M devices per square km. The total download capacity for a single 5G mobile cell must be at least 20Gbps, the International Telecommunication Union (ITU) has decided.

In contrast, the peak data rate for current LTE cells is about 1Gbps. The incoming 5G standard must also support up to 1 million connected devices per square kilometre, and the standard will require carriers to have at least 100MHz of free spectrum, scaling up to 1GHz where feasible. These requirements come from the ITU's draft report on the technical requirements for IMT-2020 (aka 5G) radio interfaces, which was published Thursday. What Is 4G LTE? You’ve heard it in commercials, seen it plastered across billboards, and maybe even read about it in your cellphone plan.

What Is 4G LTE?

But what is 4G LTE, and how do its speeds and coverage compare to other 3G and 4G networks? A History of 3G and 4G To understand what LTE is–beyond “a really fast network”–we have to take a step back in time. You probably remember when the 3G, or 3rd generation, standard was a big deal in the 2000s–it made accessing the internet on your phone significantly faster and more convenient. 3G is required to meet IMT-2000 (International Mobile Telecommunications-2000) technical standards, which means a peak download rate of 200 Kbps, or 0.2 Mbps. Logically, the next step after 3G–the third generation of wireless mobile communications technology–would be 4G, or the fourth generation. Forget digital natives. Here’s how kids are really using the Internet.

If that declaration comes as a relief, you’re most likely either an older tech user who is tired of feeling irrelevant, or a millennial frustrated with being reduced to a headphone-wearing cliché. In 2001, education consultant Mark Prensky coined this term — along with calling the analog-raised generation “digital immigrants” — to alert teachers to the emerging wave of students who’d be arriving at schools with new ways of thinking and absorbing information after growing up with computers, videogames, digital music players, video cams, cell phones and other devices.
