Google announced today that any phone running Android 7 or higher can now be used as a physical security key for two-factor authentication, giving you an even more secure way to log into Google apps than several other existing 2FA methods that Google provides right now. So when if you want a physical device to verify your login, you don’t have to buy a dongle — you can just use your phone.
There are many reasons why you might want to have your own SMTP server. But there are also many reasons why lots of businesses outsource email sending to third party services. One of the big problems with having your own SMTP server is that it is quite hard to set the whole thing up to get a solid delivery rate. What does it mean? It means that if you just naively install an SMTP server and try to send emails through it, many of your emails will not be delivered. Moreover, you will not even know that your emails did not reach their recipients. If you have decided that you want your own SMTP server, this article will help you reach a solid delivery rate – i.e. your emails will be delivered to existing mail boxes and will not get deleted as spam. If something is not configured perfectly, your emails can be lost completely without a notice, moved to Junk folders, or not accepted for a delivery. So, if you are asking following questions: How to deliver an email? How to setup MX server? How to increase the delivery rate? Just keep reading.
As this meant that there was more things that needed to be managed by the environment I was very pleased when Let’s Encrypt launched which allowed free SSL certificates. However it did not work immediately for internal systems because the challenge method needed to be able to access a website on a public address! I was not prepared to punch a hole through my firewall every 90 days. But now there is a DNS challenge for Let’s Encrypt.
I don't use Google Analytics or any other web analytics service on dri.es. Why not? Because I don't desire to know how many people visit my site, where they come from, or what operating system they use. Because I don't have a compelling reason to track my site's visitors, I don't have to bother anyone with a "cookies consent" popup either. That is a nice bonus because the web is littered with those already. I like that dri.es is clutter-free. This was all well and good until a couple of weeks ago, when I learned that when I embed a YouTube video in my blog posts, Google sends an HTTP cookie to track my site's visitors. Be damned! After some research, I discovered that YouTube offers a privacy-enhanced way of embedding videos. Instead of linking to youtube.com, link to youtube-nocookie.com, and no data-collecting HTTP cookie will be sent. This is Google's way of providing GDPR-compliant YouTube videos.
This Instructable will show you how to make a Raspberry Pi powered robotic drum machine. It really is a fun, creative, interactive project. I’ll show you how to make the internal workings, but the actual drums is going to be up to you, giving you the opportunity to make something completely unique to you. For my machine I have used as many found items as I can... hammers from a piano rescued from my neighbours skip, a fishing net I found on the beach, an empty bake bean can, wooden spoons, an empty beer bottle, beer bottle tops and a desk bell among other things, but let your imagination go crazy - see what you have around the house, just about anything that makes a noise when hit can be used, and it will really make your project your own.
GTD—or “Getting things done”—is a framework for organizing and tracking your tasks and projects. Its aim is a bit higher than just “getting things done”, though. (It should have been called “Getting things done in a much better way than just letting things happen, which often turns out not to be very cool at all”.)
The overarching goal of Container Linux is to secure the Internet's backend infrastructure. We believe that automatically updating the operating system is one of the best tools to achieve this goal.
Here you can find a bunch of simple examples for using ct, with some explanations about what they do. The examples here are in no way comprehensive, for a full list of all the options present in ct check out the configuration specification.
I've been using Free SSL/TLS certificates from Let's Encrypt for about 18 months. Recently, I started combining Docker with Let's Encrypt. The tooling that Let's Encrypt's Certbot provides is extensive, and the whole experience of using Docker with Let's Encrypt is fantastic.
Editing images with software like Lightroom typically involves changing parameters like exposure, contrast, highlights, shadows, and so on for more than 90% of your work. These parameters are controlled using sliders that you have to drag with your mouse — sliders that emulate physical controls. But why not use such physical controls like sliders or control dials directly?
In the episode, Mike Russo shows us how we can use tools like PerfView and PerfCollect to diagnose performance problems in ASP.NET Core applications. He discusses how we can use the tools for performance analysis on both Linux and Windows servers. Also, we get a demo on how to inspect things like large object allocations, chatty SQL calls, and thread pool health.
Unless you have intentionally decided to block any news around software in your social feeds, it is likely that you have heard about Docker.
This report addresses concerns and arguments about the true cost of ink in desktop photo printing. Using the Epson SureColor P800, we conducted a series of print tests to determine how much ink is used in a full coverage 8”x10” print. From that figure we extrapolated ink usage per square inch. The objective is to share a realistic cost per print vision with inkjet users. The choice to pursue photo inkjet printing is in the end an individual economic choice.
The goal that we will try to achieve is to run a simple PHP application using the official Docker repositories for both PHP and Nginx.
