  • Google Chrome’s Ad Blocker Ready For A Global Launch Starting July 9th

    The in-house Google Chrome ad-blocker, which was initially launched for United States, Canada, and Europe last year, is ready to roll out worldwide on July 9th, Google said in a blog post.

    Google has been following the Better Ads Standards from the Coalition for Better ads for more than a year. This group’s sole purpose is to improve the user experience while surfing the web.

  • AWS gives open source the middle finger

    AWS launched DocumentDB today, a new database offering that is compatible with the MongoDB API. The company describes DocumentDB as a “fast, scalable, and highly available document database that is designed to be compatible with your existing MongoDB  applications and tools.” In effect, it’s a hosted drop-in replacement for MongoDB that doesn’t use any MongoDB code.

    AWS argues that while MongoDB is great at what it does, its customers have found it hard to build fast and highly available applications on the open-source platform that can scale to multiple terabytes and hundreds of thousands of reads and writes per second. So what the company did was build its own document database, but made it compatible with the Apache 2.0 open source MongoDB 3.6 API.

  • Red Hat’s David Egts Pushes Open Source Software for Cost-Efficient Gov’t IT Training

    David Egts, chief technologist for the North American public sector business at Red Hat (NYSE: RHT), has identified open source training as an approach that the federal government can take to advance the cybersecurity and information technology skills of its workforce, ExecutiveBiz reported Thursday.

    “[The] open source community has put effective training on a number of topics, including cloud migration and deployment and cybersecurity, well within the reach of every agency and IT administrator,” Egts wrote in a Nextgov guest piece published Wednesday.

  • Quartz AI Studio launches an open-source platform to help journalists use machine learning

    Imagine you had a personal assistant that you can task with sorting out a pile of messy documents, or ploughing through a mountain of spreadsheets to find what you are looking for.

    Enter the Quartz AI Studio, a US-based project that helps journalists use machine learning to write better stories.

    The initiative, launched in November 2018 with the support of Knight Foundation, is spearheaded by John Keefe, Quartz’s technical architect for bots and machine learning, who previously led the Quartz Bot Studio.

  • Open-source microscope targets brain imaging and disease diagnosis

    A team of researchers at Tel Aviv University in Israel has developed a new multiphoton microscopy tool, known as Pysight, for rapid 2D and 3D imaging of the brain and other tissues.

    Among other things, the team hopes that the tool could soon boost scientists' efforts to attain a deeper understand of brain dynamics, assisting in the discovery of groundbreaking treatments for a range of health problems including stroke, epilepsy and dementia.

    Pablo Blinder, who heads up the team at the Neurobiology, Biochemistry and Biophysics School and Sagol School for Neuroscience at Tel Aviv University, explains that PySight combines commercially available, off-the-shelf hardware with open-source software tailored for photon-depleted imaging conditions, such as those characteristic of rapid multiphoton microscopy.

    “[PySight’s] commercial hardware converts the noisy output of each photodetector into uniform photon detection events, and registers their absolute arrival time with a temporal precision of 100 picoseconds,” he says.

    “Its software package then reads the resulting list of photon arrival times, determines the respective origin within the brain of each detected photon, and generates volumetric movies over time.”

    In a recent paper published in the journal Optica, Blinder and his co-authors demonstrate the benefits of using PySight for tracking neuronal activity in awake mice and fruit flies. While initially developed with neuroimaging purposes in mind, Blinder reveals that the tool could just as easily be used for a range of other imaging applications - including detection of malignant cells in human patients during surgical procedures.

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
