The SSH agent is a central part of OpenSSH. In this post, I'll explain what the agent is, how to use it, and how it works to keep your keys safe. I'll also describe agent forwarding and how it works. I'll help you reduce your risk when using agent forwarding, and I'll share an alternative to agent forwarding that you can use when accessing your internal hosts through bastions.

We show that for thousands of years, humans have concentrated in a surprisingly narrow subset of Earth’s available climates, characterized by mean annual temperatures around ∼13 °C. This distribution likely reflects a human temperature niche related to fundamental constraints. We demonstrate that depending on scenarios of population growth and warming, over the coming 50 y, 1 to 3 billion people are projected to be left outside the climate conditions that have served humanity well over the past 6,000 y. Absent climate mitigation or migration, a substantial part of humanity will be exposed to mean annual temperatures warmer than nearly anywhere today.

Humans have gotten a lot done in 300,000 years: We invented agriculture, developed writing systems, built cities, created the internet, and shrugged off gravity to land on the moon. These innovations make our past seem long—and stuffed with significance. But in the brief history of life, everything we’ve ever accomplished fits into a tiny sliver of time—just 0.008 percent of the entire continuum shown below. This is how the rise of the animal kingdom stretches out compared with our relatively insignificant existence.
That’s because we eat a ton of meat, and the vast majority of it comes from factory farms. In these huge industrialized facilities that supply more than 90 percent of meat globally — and around 99 percent of America’s meat — animals are tightly packed together and live under harsh and unsanitary conditions.
“When we overcrowd animals by the thousands, in cramped football-field-size sheds, to lie beak to beak or snout to snout, and there’s stress crippling their immune systems, and there’s ammonia from the decomposing waste burning their lungs, and there’s a lack of fresh air and sunlight — put all these factors together and you have a perfect-storm environment for the emergence and spread of disease,“ said Michael Greger, the author of Bird Flu: A Virus of Our Own Hatching.
To make matters worse, selection for specific genes in farmed animals (for desirable traits like large chicken breasts) has made these animals almost genetically identical. That means that a virus can easily spread from animal to animal without encountering any genetic variants that might stop it in its tracks. As it rips through a flock or herd, the virus can grow even more virulent.
Greger puts it bluntly: “If you actually want to create global pandemics, then build factory farms.”
Dangerzone, a new open source tool that First Look Media just released at the Nullcon 2020 hacker conference in Goa, India, aims to solve this problem. You can install dangerzone on your Mac, Windows, or Linux computer, and then use it to open a variety of types of documents: PDFs, Microsoft Office or LibreOffice documents, or images. Even if the original document is dangerous and would normally hack your computer, dangerzone will convert it into a safe PDF that you can open and read.
When dangerzone starts containers, it disables networking, and the only file it mounts is the suspicious document itself. So if a malicious document hacks the container, it doesn’t have access to your data and it can’t use the internet, so there’s not much it could do.
Not so long ago, we found out that Tokyo’s Akihabara Station has a bank of vending machines stocked with a huge array of delicious milk-based drinks, with all sorts of fruit, tea, and coffee flavorings to tempt you. But while those are great for quenching your thirst or satisfying your sweet tooth, what about when you’re feeling hungry?
Watch a kabuki classic at home: National Theatre uploads Yoshitsune Senbon Zakura for free【Video】 | SoraNews24 -Japan News-

Japan’s National Theatre has risen to the occasion after the cancellation of Yoshitsune Senbon Zakura (Yoshitsune and the Thousand Cherry Trees), which was originally scheduled to open for audiences in Tokyo on March 3 of this year. Instead, the performance, sans audience, will be posted to the theatre’s online YouTube channel. In fact, the play, split into three videos, is available for viewing right now, and will be free to watch to your heart’s content until April 30, 3:00 p.m. JST.
Japanese language exercises aimed at school children but also great for non-native learners like me. For me it didn't work in Firefox, which is my preferred browser, but this could possibly be because of my
paranoid privacy-enhancing browser extensions.
A lot of the information that gets passed around the Linux community is really good, however, sometimes the information surrounding this topic specifically is not always of the highest quality and it can be difficult to decipher fact from fiction.
In light of the fact that I stand by my previous article, and under the realization that I’m really just some guy on the internet; I thought it would be best to reach out to a few experts and see what they say regarding antivirus software on Linux. I thought it was important that the information I passed on was coming from trusted and well-known vendors in both the Operating System space, as well as the perspective of the antivirus makers, and in that regard I will keep my own commentary to a minimum and let the experts speak for themselves.
Spoiler: For Linux itself, no. For the protection of Windows machines, yes, maybe.
You need two things to effectively move fast: a culture of psychological safety and smart investments in tooling. Employees need to feel empowered to speak up if things are moving too fast—if they are concerned about why a feature is being built and to identify gaps in the processes. They need to feel they won’t be blamed when something breaks. Building this requires empathy, open communication, and teamwork. This psychological safety is the foundation of being able to move quickly and quickly recover when things break.
Next up is selecting the right tooling and processes. Invest in tools that make things easier. Tools should be useful, usable, and change the underlying problems, not create more.
