Qt Creator 4.8 Beta released

Filed under

In Qt Creator 4.8 we’ll introduce experimental support for the language server protocol. For many programming languages there is a “language server” available, which provides IDEs with a whole lot of information about the code, as long as they support communicating via the protocol.

This means that by providing a client for the language server protocol, Qt Creator gets (some) support for many programming languages “for free”. Currently Qt Creator supports code completion, highlighting of the symbol under cursor, and jumping to the symbol definition, as well as integrates diagnostics from the language server. Highlighting and indentation are still provided by our generic highlighter, since they are not provided via the language server protocol.

Qt Company: Introducing the Distance Field Generator

  • Introducing the Distance Field Generator

    At least from the perspective of rendering, text is often the most complex part of a traditional two-dimensional user interface. In such an interface, the two main components are rectangular images and text. The rectangular images are often quite static, and can be represented by two triangles and four indexes into a texture atlas that is uploaded to graphics memory once and then retained. This is something that has low complexity and which the graphics hardware has been optimized to handle quickly.

    Text starts as a series of indexes into an international database of writing systems (Unicode). It is then, based on some selection algorithm, combined with one or more fonts, which is in principle a collection of shapes and some lookup tables and executable programs that convert said indexes into shapes and relative positions. These shapes, basically filled paths made out of bezier curves, then have to be rasterized at a specified size, and this can range from simple and neat outlines to complex ones with lots of detail. (By rasterization, I mean finding out how much of each target pixel, or subpixel in some cases, is covered by the shape.)

Debian: Bullseye Security, Debian XMPP Team and Raphaël Hertzog's Work

  • What to expect in Debian 11 Bullseye for nftables/iptables

    Debian 11 codename Bullseye is already in the works. Is interesting to make decision early in the development cycle to give people time to accommodate and integrate accordingly, and this post brings you the latest update on the plans for Netfilter software in Debian 11 Bullseye. Mind that Bullseye is expected to be released somewhere in 2021, so still plenty of time ahead. The situation with the release of Debian 10 Buster is that iptables was using by default the -nft backend and one must explicitly select -legacy in the alternatives system in case of any problem. That was intended to help people migrate from iptables to nftables. Now the question is what to do next.

  • Debian 11 To Further Deprecate IPTables In Favor Of Nftables Plus Promoting Firewalld

    With Debian 11 "Bullseye" the plan is to drop the "important" priority on the iptables package while promoting nftables to important. That change of priority effectively makes NFTables set to be installed by default for Debian 11 while dropping IPTables from the default package set. IPTables though is still expected to be found within the Debian 11 archive but not installed by default.

  • Debian XMPP Team: New Dino in Debian

Improved Security and Privacy Indicators in Firefox 70

The upcoming Firefox 70 release will update the security and privacy indicators in the URL bar. In recent years we have seen a great increase in the number of websites that are delivered securely via HTTPS. At the same time, privacy threats have become more prevalent on the web and Firefox has shipped new technologies to protect our users against tracking. To better reflect this new environment, the updated UI takes a step towards treating secure HTTPS as the default method of transport for websites, instead of a way to identify website security. It also puts greater emphasis on user privacy. Read more
