Flatpak is the the Linux desktop app distribution framework
21 August 2018   326

Developers presented a stable version of Flatpak 1.0 - a framework for building self-contained packages that are not tied to a specific Linux distribution. Among the supported systems: Debian, Fedora, Linux Mint and Ubuntu. Applications collected using Flatpak are runing in an isolated container outside the OS.

Flatpak-program contains only specific dependencies: the basic system and graphic libraries are connected as runtime-environments individually for each distribution. This allows you to run test or suspicious application iterations in a separate sandbox, and also to update packages without changing the system.

Key Features of Flatpak 1.0

  • Developers can separately mark out-of-date versions of packages, so during their installation, the user will receive a warning about this.
  • Applications can now create a separate sandbox and restart themself..
  • New utility flatpak-spawn. It works through the Portals API and is needed to create isolated environments and run commands on the host side.
  • Packages ca be installed through P2P (from USB-drives or on the local network) by default, with support for bundle-packages.
  • The Flathub service, containing both development tools and ready-made applications, has received the status of a stable project.
  • Stable release of the runtime platform by default Freedesktop, built using the new BuildStream system.
  • Internal reorganization of the code, improvement of overall stability and performance.

More information on the new version can be found on the Flatpak project GitHub page..

Cloudflare to Develop IPFS Gateway

According to the developers, new gateway will allow to create P2P based websites

Cloudflare told about the IPFS gateway, which will allow creating sites based on P2P network. The company said that access to content will be done without having to install special software on the devices.

As a technology feature, Cloudflare experts note decentralization. Using a standard network scheme with servers involves physical storage of data in one place. Hacking the server or damage to communications as a result of an emergency (for example, a natural disaster) will lead to inaccessibility of information or its loss. The same is threatened with information if the server owner has decided to refuse it.

The IPFS gateway combines computers, on each of which some information is stored, to the worldwide network. Therefore, the inaccessibility of one computer does not mean that the content can not be viewed or downloaded. Therefore, the key differences are two:

  1. With IPFS, anyone can freely post information instead of storing it on remote servers and paying for their services.
  2. Requests for access to data are carried out using cryptographic hashing, rather than by IP address. The query data is converted to a series of letters and numbers, by which the system finds the required files. For example, the query for any information will not like "get information that is located at IP address", but the kind "get information with hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy". This hash sum is part of the desired file and is on several computers.

The system automatically determines the authenticity of the file. If we take as an example a query with a hash sum QmXnnyufdzAWL5CqZ2RnSNgPbvCc1ALT73s6epPrRnZ1Xy, then when receiving the information it should remain the same. If the hash value differs, then the file has been changed. In other words, the hash-sum can be represented as a unique fingerprint:

Supporters of decentralization are also in a number of other companies. Mozilla employees believe that consumers should not be tied to a particular product, brand or platform. In early August 2018, developers published a version of the IoT gateway Things Gateway 0.5. In it, they realized the possibility of loading third-party icons and an interface for complex devices.
