  • Pocket’s state-by-state guide to the most popular articles in 2021

    We’re just going to say it: it feels a little bit weird to wrap up 2021 because this year feels like three years in one and an extension of 2020 simultaneously. At some point in the near future, 2020 and 2021 will be studied in history books. While we can’t predict what the history books will say, we can analyze what defined this year for us.

    We do just that in Pocket’s Best of 2021 — the most-saved, -read and -shared articles by Pocket readers, spanning culture, science, tech and more.

    As we analyzed the winning articles, we wondered what we might learn if we looked at the data state by state.

  • Celebrating Pocket’s Best of 2021

    We aren’t the only ones putting out Top 10 content lists or Year in Reviews, but we’d argue these lists are different from the rest — a cut above. Pocket readers are a discerning bunch: they gravitate to fascinating long reads that deeply immerse readers in a story or subject; explainers that demystify complex or poorly understood topics; big ideas that challenge us to think and maybe even act differently; and great advice for all facets of life. You’ll find must-read examples of all of these inside these eclectic Best of 2021 collections, from dozens of trustworthy and diverse publications.

    The stories people save most to Pocket often provide a fascinating window into what’s occupying our collective attention each year. In 2019, the most-saved article on Pocket examined how modern economic precarity has turned millennials into the burnout generation. In 2020, the most-read article was a probing and prescient examination of how the Covid-19 pandemic might end.

  • Chromium Blog: Faster Chrome - Let The Compiler do the work

    Chrome is fast, but there's always room for improvement. Often, that's achieved by carefully crafting the algorithms that make up Chrome. But there's a lot of Chrome, so why not let computers do at least some part of our work? In this installment of The Fast And the Curious, we'll show you several changes in how we build Chrome to achieve a 25.8% higher score on Speedometer on Windows and a 22.0% increase in browser responsiveness.

    [...]

    It turns out that the compiler can make even more use of that profile data for PGO. (Not a surprise - once you know where the slow spots are, exactly, you can do a lot to improve!). To make use of that, and enable further improvements, LLVM has something called the "new pass manager". In a nutshell, it's a new way to run optimizations within LLVM, and it helps a lot with PGO. For much more detail, I'd suggest reading the LLVM blog post.

    Welcome to the latest monthly overview of events from the Apache community. Here's a summary of what happened in November...

  • What is a managed IT service? | Ubuntu

    Technology is one of the main success factors for any organisation. A few decades ago, when technology (and life) were not as fast-paced as today, IT was more about keeping the lights on and maintaining business as usual operations. Today, the game has massively changed. On the roads that are ever-changing, innovation is what keeps the wheel spinning.

    If you think that the world is doing enough innovation today, then it would be very interesting to check the recent Growth & Innovation McKinsey report. This report shows that only 6% of executives are satisfied with innovation within their organisations, with the majority not being able to identify how to encourage innovation!

    So, how is innovation related to managed IT services and the speed at which organisations adopt new technologies? And even more, what is a managed IT service?

  • Dead Cells: The Queen and the Sea announced for 2022 | GamingOnLinux

  • Architecting the way: Andrew Block

    One of Andrew Block’s favorite things about Red Hat? Being able to contribute back to the open source community. He says, "As long as you are innovating and making yourself better, let’s go ahead and work better together." Block is among the first Distinguished Architects at Red Hat. Distinguished Architects are senior-level technical contributors who've continued to advance in their careers working directly with customers and applying experience and knowledge of Red Hat technologies.

  • Meet Red Hat’s bankers: Insights from Monica Sasso

    As you sit in a meeting room (virtual or in-person), take a moment to think through the perspectives, experiences and insights of those around you being brought to that meeting. We did just that and quickly realized the wealth of knowledge from our colleagues at the table from around the world, who were former financial services leaders. Our "bankers," as we call them, have a broad and deep understanding of financial services because they’ve experienced it first-hand.

  • Irving Wladawsky-Berger: A Blockchain-based Framework for Safeguarding the Integrity of Real-World Assets

    Blockchains first came to light in 2008 as the architecture underpinning bitcoin, the best known and most widely held cryptocurrency. It’s a truly brilliant architecture built on decades-old fundamental research in cryptography, distributed data, game theory and other advanced technologies. The blockchain’s original vision was limited to enabling bitcoin users to transact directly with each other with no need for a financial institution or government agency to certify the validity of the transactions. But, like the Internet and other transformative technologies, blockchain has now transcended its original objectives. Blockchains are a kind of distributed ledger technologies (DLT), which also include non-blockchain DLTs. Over the past decade, an increasing number of people, including me, consider blockchains and DLTs as major next steps in the evolution of the Internet. In 2016 the World Economic Forum (WEF) named The Blockchain in its annual list of Top Ten Emerging Technologies citing its potential to fundamentally change the way markets and governments work. “Like the Internet, the blockchain is an open, global infrastructure upon which other technologies and applications can be built,” said the WEF. “And like the Internet, it allows people to bypass traditional intermediaries in their dealings with each other, thereby lowering or even eliminating transaction costs.”

  • Flathub to verify first-party apps and allow developers to collect monies | GamingOnLinux

    Flathub and Flatpak packages are the future of Linux apps according to more people and GNOME are continuing to invest in it. They have some big plans to improve it too. Writing in a new blog post on the GNOME Foundation website, they went over a number of things and not just Flathub related but that's what we're going to focus on for this article. The plans actually sounds pretty good! Firstly, Flathub is going to gain a way to process and verify apps from first-party teams. As in, developers who directly publish their app and manage the Flatpak package process for Flathub. A way to actually properly distinguish official apps from community builds will be quite important for so many reasons (security, privacy and so on). Not only that but GNOME want to give developers a way to collect donations and subscriptions too, which is also important to help make it more sustainable. Sounds like it's possible a way will be added for developers to share some of the revenue with Flathub too, ensuring it too is sustainable.

Audiocasts/Shows: Hackaday Podcast, Linux From Scratch, Linux Mint 20.3 "Una" Xfce, and More

  • Hackaday Podcast 152: 555 Timer Extravaganza, EMF Chip Glitching 3 Ways, A Magnetic Mechanical Keyboard, And The Best Tricorder Ever | Hackaday

    Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi as they bring you up to speed on the best stories and projects from the week. There’s some pretty unfortunate news for the physical media aficionados in the audience, but if you’re particularly keen on 50 year old integrated circuits, you’ll love hearing about the winners of the 555 Timer Contest. We’ll take a look at a singing circuit sculpture powered by the ESP32, extol the virtues of 3D printed switches, follow one hacker’s dream of building the ultimate Star Trek tricorder prop, and try to wrap our heads around how electronic devices can be jolted into submission. Stick around to the end as we take a close look at some extraordinary claims about sniffing out computer viruses, and wrap things up by wondering why everyone is trying to drive so far.

  • Noodlings 36 | The Wires and Tubes

    This is my segment where I like to look back in time and see how the world of technology has advanced and how things have stayed the same. I find we often forget how far we have come and how good we have it while not always remember how we got here. Having some historical perspective on computers and technology can help to drive some appreciation for what we have today.

Proprietary Security: Windows and McAfee

  • This Week In Security: NetUSB, HTTP.sys, And 2013’s CVE Is Back | Hackaday

    A serious problem has been announced in Windows Server 2019 and Windows 10, with some versions vulnerable in their default configurations. The problem is in how Windows handles HTTP Trailer packets, which contain extra information at the end of normal HTTP transfers. There is a PoC available that demonstrates a crash. It appears that an additional information leak vulnerability would have to be combined with this one to produce a true exploit. This seems to be a different take on CVE-2021-31166, essentially exploiting the same weakness, and working around the incomplete fix. This issue was fixed in the January patch set for Windows, so make sure you’re covered.

  • CISA Adds Four Known Exploited Vulnerabilities to Catalog | CISA

    CISA has added four new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence that threat actors are actively exploiting the vulnerabilities listed in the table below. These types of vulnerabilities are a frequent attack vector for malicious cyber actors of all types and pose significant risk to the federal enterprise.

  • McAfee Releases Security Update for McAfee Agent for Windows  | CISA

    McAfee has released McAfee Agent for Windows version 5.7.5, which addresses vulnerabilities CVE-2021-31854 and CVE-2022-0166. An attacker could exploit these vulnerabilities to take control of an affected system.

  • FTP server container Podman fast and right and 4 dirty steps

    FTP server container stands for “File Transfer Protocol” and is an excellent protocol for downloading files from a remote or local server or uploading files onto the server. Using FTP proves to be a primary task after it has been set up correctly. It works by having a server listening for connections (on port 21 by default) from clients. The clients can access a remote directory with their user account and then download or upload files there, depending on the permissions that have been granted to them. It’s also possible to configure anonymous authorization, which means users will not need their account to connect to the FTP server. On Centos Linux, there are many different FTP server containers and client software packages available. You can even use default GUI and command-line tools as an FTP client. In addition, a stylish and highly-configurable FTP server package is vsftpd, known for many Linux systems, including Centos. This guide will go over the step-by-step instructions to install vsftpd on Centos. We’ll also see how to configure the container FTP server through various settings, then use the command line, GNOME GUI, or FTP client software to connect to the FTP server. Creating FTP users tutorial.

  • How to Back Up Your Linux System With Rsync - JumpCloud

    It’s easy to take for granted the importance of having a server backup — until you experience a system failure, a natural disaster, or a malware attack. This can potentially paralyze your business through the loss of vital records such as financial and customer data. Your ability to recover will only be as good as your last backup. Server backups provide the much-needed confidence that data is not lost and can be recovered in case of any eventuality. However, each operating system has a different way to handle this, and while some provide built-in utilities to accomplish this, others must be established from the ground up. Like many other areas of management, Linux operating systems have more options, but require more knowledge to set them up successfully.
