Apache Rya matures open source triple store database

Filed under
OSS

The open source Apache Rya database effort is continuing to move forward as it reaches a new level of project maturity and acceptance.

Rya (pronounced "ree-uh") is an RDF (resource description framework) triple store database. The project started at the U.S. government's Laboratory for Telecommunication Sciences with an initial research paper published in 2012.

The project joined the Apache Software Foundation (ASF) in 2015 as an incubated project, and in September 2019 achieved what is known as Top-Level Project status. The Top-Level status is an indication and validation of the project's maturity, code quality and community. The ASF is home to Hadoop, Spark and other widely used database and data management programs.

The Spectre Mitigation Impact For Intel Ice Lake With Core i7-1065G7

Filed under
Graphics/Benchmarks

For those wondering if -- or how much -- of a performance impact mitigations still make regarding Spectre for Intel's long-awaited 10nm+ Ice Lake processors, here is the rundown on the mitigation state and the performance impact.

One of the areas that Phoronix readers have requested testing on with the recent purchase of the Dell XPS 7390 with Core i7 1065G7 is regarding the mitigation state and performance. Ice Lake with its Sunny Cove microarchitecture -- similar to Cascade Lake -- is no longer affected by Meltdown, MDS, or L1TF / Foreshadow.

Security: WireGuard, Birds and Updates

  • WireGuard Restored In Android's Google Play Store After Brief But Controversial Removal

    After Google dropped the open-source WireGuard app from their Play Store since it contained a donation link, the app has now been restored within Google's software store for Android users but without the donation option.

    The WireGuard app for Android makes it easy to setup the secure VPN tunnel software on mobile devices, similar to its port to iOS and other platforms. The WireGuard apps are free but have included a donation link to the WireGuard website should anyone wish to optionally make a donation to support the development of this very promising network tech.

  • Letting Birds scooters fly free

    At that point I had everything I need to write a simple app to unlock the scooters, and it worked! For about 2 minutes, at which point the network would notice that the scooter was unlocked when it should be locked and sent a lock command to force disable the scooter again. Ah well.

    So, what else could I do? The next thing I tried was just modifying some STM firmware and flashing it onto a board. It still booted, indicating that there was no sort of verified boot process. Remember what I mentioned about the throttle being hooked through the STM32's analogue to digital converters[3]? A bit of hacking later and I had a board that would appear to work normally, but about a minute after starting the ride would cut the throttle. Alternative options are left as an exercise for the reader.

    Finally, there was the component I hadn't really looked at yet. The Quectel modem actually contains its own application processor that runs Linux, making it significantly more powerful than any of the chips actually running the scooter application[4]. The STM communicates with the modem over serial, sending it an AT command asking it to make an SSL connection to a remote endpoint. It then uses further AT commands to send data over this SSL connection, allowing it to talk to the internet without having any sort of IP stack. Figuring out just what was going over this connection was made slightly difficult by virtue of all the debug functionality having been ripped out of the STM's firmware, so in the end I took a more brute force approach - I identified the address of the function that sends data to the modem, hooked up OpenOCD to the SWD pins on the STM, ran OpenOCD's gdb stub, attached gdb, set a breakpoint for that function and then dumped the arguments being passed to that function. A couple of minutes later and I had a full transaction between the scooter and the remote.

    The scooter authenticates against the remote endpoint by sending its serial number and IMEI. You need to send both, but the IMEI didn't seem to need to be associated with the serial number at all. New connections seemed to take precedence over existing connections, so it would be simple to just pretend to be every scooter and hijack all the connections, resulting in scooter unlock commands being sent to you rather than to the scooter or allowing someone to send fake GPS data and make it impossible for users to find scooters.

Landing this week in xfce4-panel was this commit providing a dark mode preference for Xfce4, similar to the growing trend with other desktops/UIs for those wanting a "dark mode" interface.

Enabling this option will request the GTK dark theme variant of capable themes. For a long time now GTK has exposed a property (gtk-application-prefer-dark-theme) for preferring dark themes while now is being tapped by xfce4-panel.

Cascade Lake vs. Rome With MrBayes, dav1d 0.5, OSPray, SVT-VP9, OIDn + Other Benchmarks

Filed under
Graphics/Benchmarks

While swapping around CPUs for the AMD EPYC vs. Intel Xeon Cascade Lake testing of Facebook's RocksDB enterprise workload testing, I also took the opportunity for running some other recently updated test profiles on these EPYC/Xeon parts under test.

These newest results shouldn't be particularly surprising but are primarily just benchmark results for some updated versions of existing tests. With recently a number of updated test profiles on OpenBenchmarking.org against the upstream programs under test, here are simply those latest performance numbers when running on the dual Intel Xeon Platinum 8280 and the AMD EPYC 7601 Naples and EPYC 7502 / 7642 / 7742 Rome processors all in 2P configurations. The setups were the same as from the RocksDB testing with running the newly-minted Ubuntu 19.10.

  • conf.kde.in is live!

    At least twice I have been to India. Atil Chitnis closed FOSS.IN in 2008, and I wrote about that only briefly, and in 2011 there was conf.kde.in in Bangalore which I wrote about some more.

    During one of those conferences I fell asleep on the ground in the hall at the KDE booth.

Linux Candy: Ternimal – animated lifeform in the terminal

Filed under
Software

Who loves eye candy? Don’t be shy — you can raise both hands!!

Linux Candy is a new series of articles covering interesting eye candy software. We’re only going to feature open-source software in this series.

I’m not going to harp on about the tired proverb “All work and no play makes Jack a dull boy”. But there’s a certain element of truth here. If you spend all day coding neural networks, mastering a new programming language, sit in meetings feeling bored witless, you’ll need some relief at the end of the day. And what better way by making your desktop environment a bit more memorable, zany, and idiosyncratic.

For this article in the Linux Candy series, we’re looking at Ternimal. That’s not a typo. It’s called Ternimal. Think of the name as a hybrid of terminal and animal.

Ternimal simulates a lifeform in the terminal using Unicode block symbols. It’s a script written in Rust. It has no dependencies and consumes very few resources.

Can Linux improve ATM security?

Filed under
Linux
Security

While ATM security is not necessarily "life critical" as with many other industries (think transportation, medical and some industrial applications) there are certainly financial and identity theft risks associated with these devices.

Plenty of info is available on the web regarding various ATM attack vectors, estimated number of annual hacks and the cost to the industry. The question we will ponder here is very specific: Would replacing the Windows operating system in an ATM with a Linux-based one improve security? Most experts believe the answer is yes.

Today's ATM looks much like a personal computer on your desk. It runs the world's most popular desktop operating system — Windows —on the world's most popular hardware: Intel motherboards.

But therein lies part of the problem. Being "most popular" means there are few barriers to keeping the bad guys from simulating the internals of a typical ATM. This fact alone makes Windows more prone to attack than alternatives.

Linux

If you haven’t been paying attention to a little Linux desktop distribution called Deepin, it’s time to put it on your radar. Nevermind that Huawei chose Deepin to ship on their MateBook laptop lineup. Nevermind that Deepin Cloud Sync is a killer, forward-thinking feature that every Linux distro needs to adopt. Nevermind that its elegant slide-out control center resembles something sexy and sensible straight out of the future. But looking toward 2020, Deepin is poised to be absolutely stunning.

This is without question the most beautiful environment I’ve ever laid eyes on. I’ve gone from admiring it as an elevated Desktop Linux distribution to downright salivating over it.

Qt Creator 4.11 Beta released

Filed under
KDE

We are happy to announce the release of Qt Creator 4.11 Beta!

We added experimental support for Qt for WebAssembly and Qt for MCUs.

We improved the general handling of configuring, building and running projects in so many smaller ways that I fail to choose anything for being highlighted here.

If you use CMake 3.14 or later we now use CMake's file-base API for configuring and parsing projects. Which behaves much more reliably than the previous server-mode, especially if you also use CMake from a terminal or other applications.

  • Crusader Kings II goes free to play, Paradox games on sale and possibly Crusader Kings III coming

    It's Friday morning, I've got my coffee ready so let's go over what's going on what Paradox Interactive. They've got a lot going on right now!

    Firstly, it seems Crusader Kings II has gone fully free to play. This doesn't appear to be time limited either, the Steam store page properly states it's "Free To Play" and on Twitter, the Crusader Kings official account said "This is not a joke - Crusader Kings 2 is free to play!".

    Considering it has a rather large amount of DLC, it's seven years old and it's been given out temporarily free for keeps before, it seems like a good idea to set the base game free for everyone now. Looks like all the DLC is also 50% off.

  • With a fabric world, Woven looks like a unique adventure coming to Linux next month

    Alterego Games and StickyLock Studios have announced that their adventure game Woven is releasing on November 15. Woven certainly looks pleasant, with a world that looks like someone stitched it together and your character is a stuffed animal.

    Woven is a laid-back adventure and exploration game, where you roam a world made of fabric. They said all the stuffed animals once lived in peace and all appears well at first glance, but not everything is as it seems. As you progress through Woven as the clumsy character Stuffy you customize them with different animal shapes to gain new abilities, solve puzzles and attempt to find out why the world is being invaded by metal machines.

  • The Scream Fortress XI event has launched for Team Fortress 2

    While perhaps not as big as previous events, it's still a good time to boot up Team Fortress 2 again and have a blast. Dust off your crazy mask, pick a silly weapon skin and dive in.

  • X4: Foundations update 2.60 is out, X4: Split Vendetta and the big 3.0 update both delayed

    A couple of bits of news from Egosoft to share for their massive space sci-fi sandbox X4: Foundations.

  • Fantasty tactical RPG Wildermyth blends a mix of hand-painted 2D and 3D art & arrives on Steam soon

    With character art during the turn-based battles that look like paper cutouts in a 3D environment, Wildermyth certainly has a strange and lovely charm to it.

    Currently available on itch.io were users have been testing it for some time, Worldwalker Games have now announced that their character-driven tactical RPG will enter Early Access on Steam on November 13. In Wildermyth, your party will be tasked with defending the lands from various threads, switching between the turn-based combat and making decisions on the over-world map. It has choice-based comic-styled events, which can end up changing your heroes appearance, personalities, relationships, and abilities.

How I built and maintain Cantata, an open source music player

Filed under
Interviews
OSS

This is the third in a series of conversations with developers who build and maintain open source music players. Craig Drummond is the developer and maintainer of Cantata, an open source music player that acts as a frontend (client) to the Music Player Daemon (MPD) music server. I have two small headless computers at home configured as music servers—one connected to our stereo in our living room, one in my upstairs office. I first ran into Cantata while I was looking for a way to control these servers, and wow, it is one impressive piece of work.

I was interested in learning more about Cantata, so I was grateful when Craig agreed to do this interview (which has been lightly edited for length and clarity). Without further ado, let’s chat with Craig.
