  • Brendan Gregg: Moving my US tech job to Australia

    I've moved from the San Francisco Bay Area to Sydney, Australia, where I will continue the best job so far of my career: Performance engineering at Netflix. I'm grateful for the support of Netflix engineering management, Netflix HRBPs, and others for helping to make this happen. While my move is among the first from the Linux cloud teams, Netflix has had staff in Australia for years (for content, marketing, and the FreeBSD OCA). It's been a privilege and an adventure to work in Silicon Valley with so many amazing people. But I'm now excited about my new adventure: Doing an advanced tech role remotely from Australia. I know others who have also left the Bay Area or are planning to. Back in 2015 we'd have BPF (iovisor) meetups in Santa Clara and most contributors would be there in person, with some having travelled. Now we're more scattered, either to other US cities or worldwide. As another indicator of tech moving elsewhere, last year brought the [headline]: "Bay Area's share of VC deals predicted to fall below 20% for first time in 2021." Day to day things won't be much different. I'm still online, doing the same work, answering the same emails. And many of us expect (when travel is possible) to make regular visits to the US for company-wide meetings and events. I think some coworkers will still see me occasionally in the US office and won't even realize I've moved.

    Linux has been described as the world's most successful open source project, and it's all engineers working remotely. There's no Linux kernel headquarters where all the engineers sit in an open office layout, typing furiously then dashing for the break room coffee during kernel builds, and where maintainers can yell across the room at someone for their bad patch (when it's Linus yelling, everyone takes off their headphones to listen). That doesn't happen. Engineers are remote, and may only meet once or twice a year at a Linux kernel conference. And it's worked very well for years. Another example of remote work I've already done is book writing. Last year I published [Systems Performance 2nd Edition], which I wrote from my home office with help from remote contributors. The entire project was run via emails, a Google drive, and Google docs, and was delivered to the publisher on time.

  • OpenZFS 2.1-rc6 Released - Will Now Scale Worker Threads With CPU Core Count - Phoronix

  • Launchpad News: Comment editing is now possible

    The first request for this feature dates back from 2007. Since then, Launchpad increased a lot in terms of new features, and the other priorities took precedence over that request, but the request was still more than valid. More recently, we managed to bump the priority of this feature, and now we have it: users are now allowed to edit their comments on Launchpad answers, bugs and merge proposals!

    This has been available in the API for a few days already, but today we finally released the fresh new pencil icon in the top-right corner of your messages. Once you click it, the message is turned into a small form that allows you to edit your message content.

  • openSUSE Tumbleweed – Review of the week 2021/21

    Dear Tumbleweed users and hackers,

    During this week, we have finalized the UsrMerge project in openSUSE:Factory. Future snapshots will have /bin as a symlink to /usr/bin, and /lib(64) as symlink to /usr/lib(64). This is also the reason why the last snapshot tested and published was 0424. After that, I was keeping OBS busy with a full bootstrap and rebuild of Tumbleweed. But let’s first focus on the things that have been delivered during the last week, namely the 4 snapshots 0520, 0521, 0522, and 0524.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • 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.
