Developers of nano, a consol text editor for Unix-systems, announced the release of the third version of the program. In nano 3.0, ASCII processing and file reading are accelerated, new keyboard shortcuts are added and bugs related to text display are fixed.

What's New in nano 3.0

  • The speed of reading files was increased by 70%, and the processing of ASCII text has doubled.
  • Changed the way to delete a word at the end of the line.
  • The Ctrl + Delete key combination now erases the word behind the carriage, Ctrl + Shift + Delete - the previous one, and Alt + Q searches in the opposite direction.
  • Checking the spelling of external tools can be disabled.
  • Fixed row numbering error when opening multiple files.
  • The formatter command and the searchagain function have been removed, so Alt + W now performs findnext by default.
  • The No-Convert button is moved to the Insert menu.
  • The Backup and New-Buffer buttons are removed from the main menu, but remain in Write-Out and Insert, respectively.
  • The program ignores pressing Esc if followed by a command key combination.
  • The rcfile error messages are no longer hidden in the Linux console.

GNU nano is a free text editor for use in the UNIX console and Unix-like systems. It is a copy of the Pico editor built into the Pine mail client. In the future, the application will receive syntax highlighting, regular expression support for searching and replacing, as well as a multi-level clipboard and other features not found in Pico.

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.
