  • Instagram: What’s the Technology Behind This Social Media Platform?

    It runs “Natty Narwhal (Ubuntu Linux version 11.04) on Amazon EC2. Though the developers found out that lower versions of Ubuntu had varieties of random freezing incidents on Amazon EC2, they are certain the Linux 11.04 has been firm.

  • Four key tactics to better deliver APIs and improve customer experience through open banking

    Digital leaders are embracing open banking as a cornerstone to their banking distribution strategy. They are using APIs to connect with partners and bring innovative digital services to their customers who continue to seek better experiences.

    More broadly, customers want banking services that integrate into their digital life, explains Capgemini in its World Retail Banking Report 2018. "That’s why it makes strategic sense for banks to support the API-led economy and collaborate with third-parties to offer new-age services," the report says.

  • Krazy Parties At KubeCon Barcelona

    Are you all set to attend the upcoming KubeCon in Barcelona? They have a jam-packed schedule for technical sessions, workshops, and great talks.

    But this KubeCon is special. “This year we’ll be celebrating Kubernetes’ 5th anniversary!,” said Janet Kuo, Software Engineer at Google, Co-Chair of KubeCon + CloudNativeCon.

  • Announcing Enarx for running sensitive workloads

    Running software is something that most of us do without thinking about it. We run in "on premises"—our own machines—or we run it in the cloud - on somebody else's machines. We don't always think about what those differences mean, or about what assumptions we're making about the securtiy of the data that's being processed, or even of the software that's doing that processing. Specifically, when you run software (a "workload") on a system (a "host") on the cloud or on your own premises, there are lots and lots of layers. You often don't see those layers, but they're there.

  • Monitoring For Organizations At Scale With M3 And Prometheus

    For the past few years Prometheus has solved the monitoring needs of many and it is exceptional at what it does. Being the second project to graduate from CNCF incubation, Prometheus has exploded in popularity and is the monitoring tool of choice for many cloud native adopters. While Prometheus is great at real time monitoring, it was not designed to be a long term persistent store of metrics.

  • KubeCon Barcelona: The New SUSE, and SUSE CaaS Platform.

    In a short while, SUSE will become the largest independently operating open source company in the world. Some have branded this era, “The New SUSE and wow it’s time to see what “The New SUSE” looks like at KubeCon Barcelona. We are here to talk about modern, Kubernetes-based application delivery solutions that you need today. We’ve upped our sponsorship and we’re ready to rock.

  • What is a Kubernetes distribution, and why would you want one?

    Kubernetes (or K8s, if you want to be cool) is currently one of the fastest growing technologies in the world of open source. These days the technology in, and associated with, Kubernetes seems almost endless – and the innovation comes just as fast. Kubernetes was first introduced in 2014 as a brainchild of the citizens and people of Google-landia. 2017 saw Kubernetes start to take off in popularity largely due to an incredibly loyal following of contributors, and by 2018, Kubernetes was looking like a de-facto standard for container orchestration. As of recent, Kubernetes has seen advances in flexibility, governance, storage, and security. As with all things open source, you can just download it from the internet, too – what a time to be alive!!!

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.

  • Security updates for Friday

Xfce4-Panel Adds Dark Mode Preference

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. Read more

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