  • Open-source tech helps companies quickly adapt during pandemic

    As the COVID-19 pandemic shakes the world, companies need to change to embrace remote work and increasingly online operations. One way to quickly adapt to these new dynamics is to use open-source tools, available for access from anywhere in the globe, according to Alan Clark (pictured), who works in SUSE’s CTO Office focusing on emerging technologies and open source.

    “Our customer sentiments are changing; their purchasing habits are obviously changing. That’s changing the services that companies need to deliver,” Clark said. “And one of the powers of open source is being able to provide that to them and deliver those services very rapidly.”

  • Zstd 1.4.5 Released With 5~10% Faster Decompression For x86_64, 15~50% For ARM64

    Facebook's compression experts responsible for Zstandard have today released Zstd 1.4.5 with more performance improvements.

    Zstandard 1.4.5 comes with faster decompression performance. On x86_64 CPUs the Zstd 1.4.5 performance benefits are in the area of 5~10%. But if you are running on Arm SoCs this time around it can be 15~50% faster. Most of the Arm decompression improvements will be on the lower end of that range but for certain SoCs under ideal conditions can be 50% faster.

  • Kernel sources for the Moto G8 Play and Nubia Play 5G are now available

    To promote such development as well as fulfilling the legal obligation regarding GNU General Public License v2, most OEMs nowadays publicly release kernel sources sometime after their devices hit the market. Now two major smartphone manufacturers, Motorola and Nubia, have released kernel sources for the Moto G8 Play and the Nubia Play 5G, respectively.

  • Instaclustr CTO on open source database as a service

    Ben Bromhead: Our original vision was wildly different and, like all good startups, we had a pretty decent pivot. When the original team got together, we were working on a marketplace for high value data sets. We took a data warehouse approach for the different data sets we provided and the access model was pure SQL. It was kind of interesting from a computer science perspective, but we probably weren't as savvy as we needed to be to take that kind of business to market.

    [...]

    Our take on it [managed Cassandra as a service] is also a little bit different from some of the other vendors in that we really take a multi-technology approach. So you know, not only are we engaging with our customers around their Cassandra cluster, but we're also helping them with the Kafka cluster, Elasticsearch and Redis.

    So what ends up happening is we end up becoming a trusted partner for a customer's data layer and that's our goal. We certainly got our start with Cassandra, that's our bread and butter and what we're known for, but in terms of the business vision, we want to be there as a data layer supporting different use cases.

  • Best Chrome Extensions for Screen Capture

    Oftentimes when you are browsing the Internet, you end up finding something that appears on your computer screen that you would like to share with others. These could be as simple as a meme that hooked you in, or as important as some error message that you need in order to consult with IT. You might even need to record your screen for a demo that explains how to use a tool or complete some task.
    At times like these, it is important to have tools that help in grabbing an image or recording your screen. This is where Chrome extensions for screen capture come into play, which come packed with features that may not be present in the default Snipping Tool.

    In this article, we will be looking at some of the best Chrome extensions for screen capture.

  • What sort of SSH keys our users use or have listed in their authorized keys files

    My first surprise is that we have so many DSA keys listed, since they're no longer supported (and those 380 ssh-dss keys are across 203 different people). People clearly don't clean out their authorized keys files very often. 670 people have RSA keys, 13 have Ed25519 keys, and 15 have some form of ECDSA keys (which implies that a few people list a bunch of ECDSA keys).

    However, that's just what people have sitting around in their authorized keys files, not what actually gets used. What actually gets used is a somewhat different picture. Here are the numbers for how many different keys of each type have been used over the course of 2020 so far: [...]

  • Microsoft is blocking the Windows 10 May 2020 Update on lots of devices [Ed: Microsoft cannot even patch its own software without breaking it]

    Microsoft is preventing a large number of devices from updating to the Windows 10 May 2020 Update. While the software company released the update last week, Microsoft has quietly acknowledged that there are a number of known issues preventing the update from being installed on a variety of PCs. Microsoft has a list of 10 issues it’s currently investigating, and 9 of them have resulted in a “compatibility hold” which stops the Windows 10 May 2020 Update from being installed via Windows Update. One issue involving unexpected errors or reboots with always-on, always-connected devices, affects devices like Microsoft’s Surface Pro 7 or Surface Laptop 3.

  • Insights into hybrid cloud: Here's what to consider

    Our interactions with businesses can happen in person, on the web, on our mobile devices, in marketplaces or via APIs. To enable these interactions, IT organizations are increasingly being driven towards hybrid IT architectures involving private cloud, public cloud, edge computing, AI/ML and more to provide multiple different routes to the customer. This mixed use of public and private clouds, possibly with some degree of workload portability, integration, orchestration, and unified management across those clouds is often referred to as hybrid cloud computing. Research shows that improving business agility and increasing IT agility are key drivers for organizations that are implementing a hybrid cloud strategy.
