Top Photo Metadata Editors (Updated 2019)

Wednesday 9th of October 2019 06:48:33 AM

A metadata editor is computer software which allows users to view and edit metadata tags interactively and save them in the graphics file. So, metadata is information that is part of the image file and contains information about the image itself and the creation of the image. It can set textual information such as title, description, exposure time, ISO value, focal length, and copyright.

Debian and Ubuntu Leftovers

  • Ritesh Raj Sarraf: Bpfcc New Release

    bpfcc version 0.11.0 has been uploaded to Debian Unstable and should be accessible in the repositories by now. After the 0.8.0 release, this has been the next one uploaded to Debian.

  • Utkarsh Gupta: Joining Debian LTS!

    Back during the good days of DebConf19, I finally got a chance to meet Holger! As amazing and inspiring a person he is, it was an absolute pleasure meeting him and also, I got a chance to talk about Debian LTS in more detail. [...] I had almost no idea what to do next, so the next month I stayed silent, observing the workflow as people kept committing and announcing updates. And finally in September, I started triaging and fixing the CVEs for Jessie and Stretch (mostly the former). Thanks to Abhijith who explained the basics of what DLA is and how do we go about fixing bugs and then announcing them. With that, I could fix a couple of CVEs and thanks to Holger (again) for reviewing and sponsoring the uploads! :D

  • Ubucon Europe 2019 in local media

    News from the new Ubuntu distribution, the exploration of the several platforms and many “how to”, rule the 4-days agenda where the open source and open technologies are in the air. The Olga Cadaval Cultural centre in Sintra, is the main stage of a busy agenda filled with several talks and more technical sessions, but at Ubucon Europe there’s also room for networking and cultural visits, a curious fusion between spaces full of history, like the Pena Palace or the Quinta da Regaleira, and one of the youngest “players” in the world of software. For 4 days, the international Ubuntu Community gathers in Sintra for an event open to everyone, where the open source principles and open technology are dominating. The Ubucon Europe Conference begun Thursday, October 10th, and extends until Sunday, October 13th, keeping an open doors policy to everyone who wants to Afterall, what is the importance of Ubucon? The number of participants, which should be around 150, doesn’t tell the whole story of what you can learn during these days, as the SAPO TEK had the opportunity to check this morning. Organised by the Ubuntu Portugal Community, with the National Association for Open Software, the Ubuntu Europe Federation and the Sintra Municipality, the conference brings to Portugal some of the biggest open source specialists and shows that Ubuntu is indeed alive, even if not yet known by most people, and still far from the “world domain” aspired by some.

Devices/Embedded: Win Enterprises and Raspberry Pi 4

  • Win Enterprises unveils Atom-based LAN gateway and compact SBC

    Win Enterprises unveiled a fanless “PL-82000” networking gateway with 6x GbE and 2x SFP ports based on an Atom C3000. It also launched a Raspberry Pi sized “MB-5000” SBC that runs Ubuntu or Win 10 on Intel Apollo Lake. We tend to forget Win Enterprises because as its name suggests, the company typically sticks to Windows-supported products. Yet, they have increasingly produced barebones products without listed OS support, such as the new PL-82000 networking appliance, as well as Linux supported systems such as the MB-5000 SBC announced back in June. (In 2017, we covered an Intel Bay Trail based MB-80580 SBC and Win IoT-380 Gateway with Linux support.)

  • Raspberry Pi 4 PCI Express: It actually works! USB3, SATA… GPUs?

    Recently, Tomasz Mloduchowski posted a popular article on his blog detailing the steps he undertook to get access to the hidden PCIe interface of Raspberry Pi 4: the first Raspberry Pi to include PCIe in its design. After seeing his post, and realizing I was meaning to go buy a Raspberry Pi 4, it just seemed natural to try and replicate his results in the hope of taking it a bit further. I am known for Raspberry Pi Butchery, after all.

  • Raspberry Pi 4 B+ - PCI Express

    Why did I do it? Because I wanted to see if it can be done. Because Raspberry Pi 4 might be the cheapest device that is PCIe capable after a relatively minor modification (if I didn't lift the capacitors when desoldering the VL805, this is literally 12 soldering points). That, in turn, can be quite handy for developing own PCIe cores for various FPGA based experiments.

    I'm sharing it to allow people to learn from this - and to dispel the myth that PCIe is somehow out of reach of hobbyists due to some concerns over signal integrity or complexities. Stay tuned for more Pi4/PCIe experimentation!

  • Becoming Better Digital Citizens Through Open Source

    The WordPress Project is on a mission to democratize publishing. As WordPress empowers more people to participate in the digital space, we have the opportunity to make sure that everyone can participate safely and responsibly. Today marks the start of Digital Citizenship Week. We are going to share how open source can be used as a tool for learners (regardless of age) to practice and model the essential parts of being a good digital citizen. [...] Digital Citizenship is for all age groups. Anyone who uses the internet on a computer, mobile device or a TV is a digital citizen. You don’t have to be tech-savvy already, maybe you are taking your first steps with technology. Digital Citizenship Week is a chance to reflect together on our impact on the digital world. It can help us to make our consumption more considered and our interaction friendlier. It enables us to make a positive difference to those around us. All of us can strive (or learn) to become better digital citizens. It can be affected by the access those teaching have had to digital skills and good practice. Adult education classes and community tech hubs play a part in basic tech skill development. Unfortunately, these are not always accessible to those in less populated geographic locations.  Open source communities like WordPress already make a difference in encouraging the principles of digital citizenship, from sharing tech skills to improving security knowledge. They give people an opportunity to learn alongside their peers and many of the resources are available regardless of location, resources, or skills.

  • MongoDB vs. MySQL: How to choose

    During the dot-com bubble in the 1990s, one common software stack for web applications was LAMP, which originally stood for Linux (OS), Apache (web server), MySQL (relational database), and PHP (server programming language). MySQL was the preferred database mostly because it was free open source and had good read performance, which fit well with “Web 2.0” apps that dynamically generated sites from the database. Later the MEAN stack, which stood for MongoDB (document database), Express (web server), AngularJS (front-end framework), and Node.js (back-end JavaScript runtime), came to prominence. The MEAN stack was attractive, among other reasons, because the only language you needed to know was JavaScript. It also needed less RAM than an equivalent LAMP stack.

Security: XML External Entity (XXE) Example and the Latest Patches

  • XML External Entity (XXE) Example

    According to OWASP, an XML External Entity attack is a type of attack against an application that parses XML input. This attack occurs when XML input containing a reference to an external entity is processed by a weakly configured XML parser. This attack may lead to the disclosure of confidential data, denial of service, server side request forgery, port scanning from the perspective of the machine where the parser is located, and other system impacts. If a parser accepts unsanitized XML, we can take advantage of that and send our own crafted external XML payload to exploit our target. This post won’t be long so let’s get into it.
