  • FLOSS Weekly 570: xs:code

    Open Source That Makes Sense. xs:code helps you pay open source developers to maintain and improve their code – so you don't have to.

    Xs:code was started with one goal in mind – empowering developers on both sides of the equation. Both open source developers, and developers who use open-source when developing for companies and R&D teams. Xs:code truly believes that creating a sustainable way to develop and use open source, is a mutual interest of developers, and commercial companies alike.

  • Open Source Software: Mitigating the Risks to Reap the Rewards

    Initially developed by Richard Stallman in 1983 and popularized by Linus Torvalds in the early 1990s, open source software has evolved tremendously over the last 37 years. Although it started out as a niche practice, it became more mainstream in the 2000s. Its value was initially verified by Sun Microsystems’ $1 billion acquisition of MySQL in 2008, and more recently by IBM’s purchase of Red Hat for $34 billion last year. Now the most popular open source software, GNU/Linux runs on nearly 70% of web servers and is maintained by more than 15,000 unique programmers around the world. However, there remains an ongoing debate within the tech industry on both the pros and cons of open source software. We’ve taken a look at a couple of each and discussed below.

  • Covid-19: Bootlin proposes online sessions for all its courses

    Like many of us, due to the Covid-19 outbreak, you may be forced to work from home, to limit your contacts with other people and fight the spread of the disease.

  • RSS: The Original Federated Social Network Protocol

    So what is RSS? The acronym has a bit of a checkered history. Currently RSS stands for Rich Site Summary, originally RDF Site Summary, but it is often known by the more common term Really Simply Syndication. Which ever name you call it by, RSS is a standardized format for listing the most recent updates for a website. The majority of websites and blogs publish a feed of updates, either in RSS format or its close cousin, the Atom Syndication Format (ATOM). YouTube channels, Podcasts, most web comics, and many news sites expose all their updates in one of these standardized formats. Most RSS readers support scanning websites to find their feeds, in formats such as RSS 0.9, 1.x, 2.x or ATOM. RSS readers poll websites regularly, and display updates from websites users are subscribed to.

  • DDoS botnets have abused three zero-days in LILIN video recorders for months

    Digital video recorders are devices installed on company networks that aggregate video feeds from local CCTV or IP camera systems and record it on various types of storage systems, like HDDs, SSDs, USB flash drives, or SD memory cards.

  • Multiple botnets are spreading using LILIN DVR 0-day

    The LILIN 0-day vulnerability is made of 3 parts: hard-coded login credentials, /z/zbin/dvr_box command injection vulnerabilities and /z/zbin/net_html.cgi arbitrary file reading vulnerabilities, /z/zbin/dvr_box provides Web services, and its web interface /dvr/cmd and /cn/cmd have a command injection vulnerability. The injected parameters have been: NTPUpdate, FTP, and NTP.

    [...]

    LILIN users should check and update their device firmwares in a timely fashion, and strong login credentials for the device should be enforced.

    The relevant malicious IPs, URLs and domains should be blocked and investigated on users’network.

Programming: micro.sth, RProtoBuf, Perl and Python

  • Introducing micro.sth

    Many developers turn their noses up at PHP, but I have a soft spot for it. For me, it's the most approachable programming language by far. It feels intuitive in a way no other languages do, and it makes it possible to cobble together a working application with just a handful of lines of code. So whenever I can't find a tool for a specific job, I try to build one myself. The latest project of mine is a case in point. I was looking for a simple application for keeping a photographic diary, and I was sure that I'd be able to find an open-source tool for that. I searched high and low, but I came back empty-handed. Sure, there are plenty of static website generators, but I'd prefer something that doesn't require me to perform the write-generate-upload dance every time I want to post a quick update. And I need something that I can use not only to maintain a simple diary, but also store notes, manage tasks, and draft articles -- all this without getting bogged down by configuring templates, defining categories, and tweaking settings. And because I want most of my content to be private, I should be able to protect access to it with a password.

  • Dirk Eddelbuettel: RProtoBuf 0.4.17: Robustified

    A new release 0.4.17 of RProtoBuf is now on CRAN. RProtoBuf provides R with bindings for the Google Protocol Buffers (“ProtoBuf”) data encoding and serialization library used and released by Google, and deployed very widely in numerous projects as a language and operating-system agnostic protocol. This release contains small polishes related to the release 0.4.16 which added JSON support for messages, and switched to ByteSizeLong. This release now makes sure JSON functionality is only tested where available (on version 3 of the Protocol Buffers library), and that ByteSizeLong is only called where available (version 3.6.0 or later). Of course, older versions build as before and remain fully supported.
