  • Qt Design Studio 1.2 Beta Offers Bridge With Sketch Vector Graphics Editor

    Qt Design Studio 1.2 Beta also introduces gradients support for shape-based items and other changes. More details on the Qt Design Studio 1.2 Beta over on the Qt blog.

  • Qt Design Studio 1.2 Beta released

    Qt Design Studio is a UI design and development tool that enables designers and developers to rapidly prototype and develop complex UIs. Both designers and developers use Qt Design Studio and this makes collaboration between the two a lot simpler and more streamlined. To get an impression, you should watch this video.

    The main addition for Qt Design Studio 1.2 is the Sketch Bridge. It is now possible to export your scenes from Sketch and import them to Qt Design Studio 1.2.

  • ESR Switches To Threadripper But His GCC SVN-To-Git Conversion Could Still Take Months

    It looks like the saga of converting the GNU Compiler Collection (GCC) source tree from SVN to Git isn't over yet and could still take months until completion. 

    As written about last week, a Linaro developer worked on a Bash script leveraging Git-SVN for converting GCC's SVN to Git as while Eric S Raymond has been working on the effort for many months using his homegrown "Reposurgeon" utility, it hasn't yet panned out. Reposurgeon in last year's form was too memory hungry and slow while ultimately he began rewriting the tool in Golang in hopes of addressing these issues.

  • digest 0.6.19

    digest creates hash digests of arbitrary R objects (using the md5, sha-1, sha-256, sha-512, crc32, xxhash32, xxhash64, murmur32, and spookyhash algorithms) permitting easy comparison of R language objects.

    This version contains two new functions adding new digest functionality. First, Dmitriy Selivanov added a fast and vectorized digest2int to convert (arbitrary) strings into 32 bit integers using one-at-a-time hashing. Second, Kendon Bell, over a series of PRs, put together a nice implementation of spookyhash as a first streaming hash algorithm in digest. So big thanks to both Dmitriy and Kendon.

  • Apache Camel development on Eclipse Che 7

    Apache Camel development is improving on Eclipse Che 7 compared to Che 6. On Che 6, it is limited to XML DSL and without classical XSD-based XML support. With Che 7, Camel Java DSL is available and XSD-based XML support is working nicely with the Camel XML DSL support. Please note that Che 7 is still in beta.

  • MIME type "text/vnd.sosi" for SOSI map data

    As part of my involvement in the work to standardise a REST based API for Noark 5, the Norwegian archiving standard, I spent some time the last few months to try to register a MIME type and PRONOM code for the SOSI file format. The background is that there is a set of formats approved for long term storage and archiving in Norway, and among these formats, SOSI is the only format missing a MIME type and PRONOM code.

  • 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.
