nomacs is a free, open source image viewer, which supports multiple platforms. You can use it for viewing all common image formats including RAW and psd images.

nomacs features semi-transparent widgets that display additional information such as thumbnails, metadata or histogram. It is able to browse images in zip or MS Office files which can be extracted to a directory. Metadata stored with the image can be displayed and you can add notes to images. A thumbnail preview of the current folder is included as well as a file explorer panel which allows switching between folders. Within a directory you can apply a file filter, so that only images are displayed whose filenames have a certain string or match a regular expression. Activating the cache allows for instantly switching between images.

nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, exposure. It has a pseudo color function which allows creating false color images. A unique feature of nomacs is the synchronization of multiple instances. With this feature you can easily compare images by zooming and/or panning at the exactly same position or even by overlaying them with different opacity.
nomacs is licensed under the GNU General Public License v3 and available for Windows, Linux, FreeBSD, Mac, and OS/2. It is free for private and commercial use. If you want to report any bugs or request new features please use our tracker.

Introduction

restic is a program that does backups right. The design goals are:

• Easy: Doing backups should be a frictionless process, otherwise you are tempted to skip it. Restic should be easy to configure and use, so that in the unlikely event of a data loss you can just restore it. Likewise, restoring data should not be complicated.

• Fast: Backing up your data with restic should only be limited by your network or hard disk bandwidth so that you can backup your files every day. Nobody does backups if it takes too much time. Restoring backups should only transfer data that is needed for the files that are to be restored, so that this process is also fast.

• Verifiable: Much more important than backup is restore, so restic enables you to easily verify that all data can be restored.

• Secure: Restic uses cryptography to guarantee confidentiality and integrity of your data. The location where the backup data is stored is assumed to be an untrusted environment (e.g. a shared space where others like system administrators are able to access your backups). Restic is built to secure your data against such attackers, by encrypting it with AES-256 in counter mode and authenticating it using Poly1305-AES.

• Efficient: With the growth of data, additional snapshots should only take the storage of the actual increment. Even more, duplicate data should be de-duplicated before it is actually written to the storage backend to save precious backup space.

• Free: restic is free software and licensed under the BSD 2-Clause License and actively developed on GitHub.
