  • Security Researchers Find Several Bugs in Nest Security Cameras

    Researchers Lilith Wyatt and Claudio Bozzato of Cisco Talos discovered the vulnerabilities and disclosed them publicly on August 19. The two found eight vulnerabilities that are based in the Nest implementation of the Weave protocol. The Weave protocol is designed specifically for communications among Internet of Things or IoT devices.

  • Better SSH Authentication with Keybase

    With an SSH CA model, you start by generating a single SSH key called the CA key. The public key is placed on each server and the server is configured to trust any key signed by the CA key. This CA key is then used to sign user keys with an expiration window. This means that signed user keys can only be used for a finite, preferably short, period of time before a new signature is needed. This transforms the key management problem into a user management problem: How do we ensure that only certain people are able to provision new signed SSH keys?

  • Texas ransomware attacks deliver wake-up call to cities [iophk: Windows TCO]

    The Texas Department of Information Resources has confirmed that 22 Texas entities, mostly local governments, have been hit by the ransomware attacks that took place late last week. The department pointed to a “single threat actor” as being responsible for the attacks, which did not impact any statewide systems.

  • Texas Ransomware Attack

    On Security Now, Steve Gibson talks about a huge ransomware attack. 23 cities in Texas were hit with a well-coordinated ransomware attack last Friday, August 16th.

  • CVE-2019-10071: Timing Attack in HMAC Verification in Apache Tapestry

    Apache Tapestry uses HMACs to verify the integrity of objects stored on the client side. This was added to address the Java deserialization vulnerability disclosed in CVE-2014-1972. In the fix for the previous vulnerability, the HMACs were compared by string comparison, which is known to be vulnerable to timing attacks.

GNOME Feeds is a Simple RSS Reader for Linux Desktops

Filed under
GNOME

Feedreader, Liferea, and Thunderbird are three of the most popular desktop RSS readers for Linux, but now there’s a new option on the scene.

GNOME Feeds app is simple, no-frills desktop RSS reader for Linux systems. It doesn’t integrate or sync with a cloud-based service, like Feedly or Inoreader, but you can import a list of feeds via an .opml file.

“Power” users of RSS feeds will likely find that GNOME Feeds a little too limited for their needs. But the lean feature set is, arguably, what will make this app appeal to more casual users.

GNU Radio Launches 3.8.0.0, First Minor-Version Release In Six Years

Filed under
GNU

The GNU Radio maintainers have announced the release of GNU Radio 3.8.0.0, the first minor-version release of the popular LimeSDR-compatible software defined radio (SDR) development toolkit in over six years.

“It’s the first minor release version since more than six years, not without pride this community stands to face the brightest future SDR on general purpose hardware ever had,” the project’s maintainers announced this week. “What has not changed is the fact that GNU Radio is centred around a very simple truth: Let the developers hack on DSP. Software interfaces are for humans, not the other way around. And so, compared to the later 3.7 releases, nothing has fundamentally modified the way one develops signal processing systems with GNU Radio: You write blocks, and you combine blocks to be part of a larger signal processing flow graph.”

IBM/Red Hat Leftovers

Red Hat
  • Accelerating the journey to open hybrid cloud with Red Hat Modernization and Migration Solutions

    The integration of technology into all areas of a business (the "digital transformation" we hear so much about) is fundamentally changing how organizations operate as well as how they deliver value to customers. An example is Lockheed Martin, who opted to undergo an eight-week agile transformation labs residency to implement an open source architecture onboard the F-22 and simultaneously disentangle its web of embedded systems. But such transformation can also create new challenges, from additional competitive pressures to increased customer expectations.

    To help overcome these challenges, Red Hat is introducing a family of solutions to help optimize infrastructure, modernize applications and accelerate innovation while supporting customers in their journey to the open hybrid cloud. Red Hat Modernization and Migration Solutions are designed to help customers realize the benefits of open technologies and adopt containers, Kubernetes and hybrid cloud-ready platforms. The family of solutions offers a path for customers from restrictive, proprietary environments to more flexible and (often) less costly open source alternatives, in an iterative approach.

  • Let’s talk about Privacy by Design

    Privacy by Design or Privacy by Default (PbD) is not a new concept. However PbD received renewed attention when the GDPR added PbD as a legal requirement. PbD refers to the process of building in technical, organizational and security measures at the beginning stage of product development and throughout the product lifecycle.

    [...]

    One PbD tool we use to build in privacy to our development process is our Privacy Impact Assessment, also known as a PIA. The PIA is a process which assists developers at the early stages in identifying and mitigating privacy risks associated with the collection and use of personal data.

    The PIA tool begins with a self assessment that asks a lot of questions about the planned project or product. This initiates a process of review by individuals trained in privacy and security. The process is collaborative and creates an on-going dialogue about privacy with respect to the product, system or application at hand.

Simplicity Linux 19.10 Alpha ISOs are here!

Filed under
GNU
Linux

We’re proud to announce the release of Simplicity Linux 19.10. It is based on Stretchdog, which in turn is based on Debian Stretch. As this is an alpha release, none of these images should be considered finished versions, and may contain bugs or issues which won’t be present in the final release. These images should also be considered to be designed for live booting rather than being installed.

All three editions of Simplicity Linux 19.10 feature Ecosia as the default search engine. This is a search engine where revenue from ads is used to plant trees. It is something we have been testing for some time, and we weren’t going to include it in the alpha releases. However, after hearing about the fires in the Amazon Rainforest, we have decided to include Ecosia in each version. It’s our way of trying to help in whatever small way we can.

Simplicity Mini 19.10 Alpha is our cut down version of Simplicity Linux. There are few local applications, instead being replaced by browser based versions of software which are run through Google Chrome. comes with Google Docs, Gmail, Netflix, Vortex Cloud Gaming, Spotify, Mega.nz, Vivaldi browser which opens on boot, Lastpass password manager, DotVPN, uBlock Origin.

Programming Leftovers

  • Animating Ptolemy’s Equant with Python, SVG, and CSS

    You will recall my previous blog post that tried to build the necessary scaffolding for me to finally write up my 2017 PyCon Ireland keynote on the structure of the Medieval universe. It ran into several problems with matplotlib animations — but, having written that post, I realized that the problem ran deeper.

    How could any animation show a Solar System, when a Solar System’s motion never exactly repeats? The orbital periods of the planets aren’t exact multiples of each other, and don’t provide a moment when the planets reach their original positions and the animation can start over again. At whatever moment an animation finished and looped back to the beginning, the planets would visibly and jarringly jump back to their original position.

  • How To Learn Any Programming Language Online in 2019

    Let’s face it, computers are everywhere these days, and the need for programmers is ever-increasing. Programming is vital to make computers be able to help us solve our everyday problems. It’s also a means to increase their speed and usability. With this in mind, it’s high time you jumped on this bandwagon and learned a language yourself!

    However, picking out the most appropriate programming language to learn is a substantial task for beginners. A good approach to making this choice is to consider the most popular programming languages, which languages are easy-to-learn, and how easy it is to find a job for beginners in these languages.

  • How to Build a Custom Anaconda Installer for R

    A frequent question on the Anaconda Community mailing list is how to package R with conda for distribution. Depending on the use case, one option may be to use conda to move environments. This requires that conda has been previously installed on the system. Another option is conda constructor, a utility for packaging a complete conda installation with Python and R packages.

    Constructor is the same utility we use to build Anaconda Distribution and Miniconda installers. It’s a multi-platform installer which means you can build an installer for Windows, Linux and macOS. It also supports a number of options to control how the installer is built. These options are documented on the GitHub constructor repository.

  • Digging into regressions

    Whenever a patch is landed on autoland, it will run many builds and tests to make sure there are no regressions. Unfortunately many times we find a regression and 99% of the time backout the changes so they can be fixed. This work is done by the Sheriff team at Mozilla- they monitor the trees and when something is wrong, they work to fix it (sometimes by a quick fix, usually by a backout). A quick fact, there were 1228 regressions in H1 (January-June) 2019.

    My goal in writing is not to recommend change, but instead to start conversations and figure out what data we should be collecting in order to have data driven discussions. Only then would I expect that recommendations for changes would come forth.

  • “Sudo Mastery” and the new Tilted Windmill Press clothing line

    Sudo Mastery, 2nd edition, is now complete. I’m doing the release slightly different this time, however.

  • Fossil Versus Git

    The feature sets of Fossil and Git overlap in many ways. Both are distributed version control systems which store a tree of check-in objects to a local repository clone. In both systems, the local clone starts out as a full copy of the remote parent. New content gets added to the local clone and then later optionally pushed up to the remote, and changes to the remote can be pulled down to the local clone at will. Both systems offer diffing, patching, branching, merging, cherry-picking, bisecting, private branches, a stash, etc.

Save Web Pages As Single HTML Files For Offline Use With Monolith (Console)

Filed under
Software

Monolith is a command line tool to save any web page as a single HTML file that contains everything needed to render web page locally, without needing a working Internet connection.

Use this to save web pages containing documentation, wiki articles, and anything else that interests you, for local/offline use. Since the web pages are saved in plain HTML, use a tool that can search in files to quickly find the web page you're looking for.

Unlike the regular "Save page as" (or Ctrl + s) option provided by web browsers to save web pages to your computer, which saves web page assets in a folder next to the saved web page, this command line tool retrieves the web page assets and converts them into base64 data URLs, using that in the document instead of the regular URLs. As a result, page assets like Javascript, CSS or images are embedded in the page HTML, so all you need is a web browser to access the locally saved web page.

  • Cantor and the support for Jupyter notebooks at the finish line

    Hello everyone! It's been almost three weeks since my last post and this is going to be my my final post in this blog. So, I want to summarize all my work done in this GSoC project. Just to remember again, the goal of the project was to add the support for Jupiter notebooks to Cantor. This format is widely used in the scientific and education areas, mostly by the application Jupyter, and there is a lot of content available on the internet in this format (for example, here). By adding the support of this format in Cantor we’ll allow Cantor users access this content. This is short description, if you more intersted, you can found more details in my proporsal.

    [...]

    This is all for the limitations, I think. Let's talk about future plans and perspectives. In my opinion, this project has reached its initial goals, is finished now and will only need maintenance and support in terms of bug fixing and adjustment to potential format changes in future.

    When talking more generally, this project is part of the current overall development activities in Cantor to improve the usability and the stability of the application and to extend the feature set in order to enable more workflows and to reach to a bigger audience with this. See 19.08 and 18.12 release announcements to read more about the developments in the recent releases of Cantor. Support of the Jupyter notebook format is a big step into this direction but this not all. We have already many other items in our backlog like for the UX improvements, plots integration improvements going into this direction. Some of this items will be addressed soon. Some of them are something for the next GSoC project next year maybe?

    I think, that's all for now. Thank you for reading this blog and thank you for your interest in my project. Working on this project was a very interesting and pleasant period of my life. I am happy that I had this opportunity and was able to contribute to KDE and especially to Cantor with the support of my mentor Alexander Semke.

  • My Open-Source Activities from January to August 2019

    Debian is a general-purpose Linux distribution that is widely used on the planet. I am a Debian Developer who works on packages related to Android SDK and the Java ecosystem.

    I started a new package in an attempt to build the Android framework android.jar using the upstream build systems involving Ninja, Soong and others. Since the beginning we have been writing our own (very simple) makefiles to build the binaries in AOSP because their build logic tends to be simple and straightforward, until we worked on android.jar. Building it requires digging in so much code that it became incredibly hard to maintain, which is why we still haven’t brought in any newer version since android-framework-23. This is problematic as developers can’t build any apps that target Android 7+.

    After a month of work, this package is finally done. After all its dependencies are packaged in the future, it will be good to upload. This is where the students of Google Summer of Code (GSoC) come in!

    Another well-known fact about Turing was his conviction for "gross indecency" because of his homosexuality, and the posthumous apology and pardon issued over more a half a decade after Turing’s death.

    But beyond all of this, who was Alan Turing?

    Here are six books that delve deeply into the life and legacy of Alan Turing. Collectively, these books cover his life, both professional and personal, and work others have done to build upon Turing’s ideas. Individually, or collectively, these works allow the reader to learn who Alan Turing was beyond just a few well-known, broad-stroke themes.

28 facts about Linux for its 28th birthday

Filed under
Linux

Nearly three decades ago, Linus Torvalds sent the email announcing Linux, a free operating system that was "just a hobby" and not "big and professional like GNU." It's fair to say that Linux has had an enormous influence on technology and the world in general in the 28 years since Torvalds announced it. Most people already know the "origin story" of Linux, though. Here's 28 things about Linux (the kernel and larger ecosystem) you may not already know.

1 - Linux isn't very useful alone, so folks took to creating Linux distributions to bundle user software with it, make it usable and easier to install. The first Linux distribution was Softlanding Linux System (SLS), first released in 1992 and using the .96p4 Linux kernel.

You could buy it on 5.25" or 3.5" floppies, or CD-ROM if you were high-tech. If you wanted a GUI, you needed at least 8MB of RAM.

2 - SLS didn't last, but it influenced Slackware Linux, which was first released in 1993 and is still under development today. Slackware is the oldest surviving Linux distribution and celebrated its 26th birthday on July 17th this year.

3 - Linux has the largest install base of any general purpose operating system. It powers everything from all 500 of the Top 500 Supercomputers to Android phones, Chomebooks, and all manner of embedded devices and things like the Kindle eBook readers and smart televisions. (Also the laptop used to write this post.)

LibreOffice 6.3 - Waiting for a miracle

Filed under
LibO
Reviews

LibreOffice 6.3 is a powerful, rich office suite, and the fact it comes with no strings attached, the string to your purse included, is a commendable thing. But it is not enough. Simply isn't. Functionality is what matters, and if the program cannot satisfy the necessary needs, it's not really useful. Maybe on the scale of un-value, it's less un-valuable than something that costs a lot of money, but you still don't get what you require.

And in this regard, LibreOffice 6.3 doesn't quite cut it. I mean, you can still use it happily - I know I will, it does an okay job, and you can create files and export to PDF and all that. But then, working with Office files is pretty much a no-go, the style management is inefficient, and the UI layouts are somewhat clunky. I also feel the momentum has slowed, and the great, amazing hope that was there when LibreOffice was born is just a thing of mildly apathetic momentum now. True, this ailment grips the entire open-source world, and Linux in particular, but it doesn't change the fact that the hope is slowly dwindling. All in all, worth testing, but a solution to all office problems, LibreOffice 6.3 ain't.
