  • Intel Icelake Thunderbolt Support Still Being Squared Away For Linux - Hopefully For 5.4

    Intel Icelake laptops will soon be hitting store shelves and a vast majority of the Linux support has been squared away for many months. Unfortunately one bit still not mainlined is the Thunderbolt support.

    Back in July we wrote about the Icelake Thunderbolt support still not merged yet while Icelake's Gen11 graphics and other new processor features have all been squared away for several kernel releases in ensuring good launch-day support. With Icelake, the Thunderbolt functionality has moved onto the SoC itself (sans the Thunderbolt power delivery) and that's taken additional time for getting the Linux kernel support in order.

  • OBS Studio 24.0 Will Let You Pause While Recording, Other New Options

    For those using OBS Studio for cross-platform live-streaming and screen recording needs, OBS Studio 24.0 is on the way but out first is their release candidate to vet the new features coming into this big update.

  • Kontact and Google Integration Issues

    Lately there were some issues with the Google integration in Kontact which caused that it is no longer possible to add new Google Calendar or Gmail account in Kontact because the log in process will fail. This is due to an oversight on our side which lead to Google blocking Kontact as it did not comply with Google’s policies. We are working on resolving the situation, but it will take a little bit.

    Existing users should not be affected by this - if you already had Google Calendar or Gmail set up in Kontact, the sync should continue to work. It is only new accounts that cannot be created.

    In case of Gmail the problem can mostly be worked around when setting up the IMAP account in KMail by selecting PLAIN authentication1 method in the Advanced tab and using your email and password. You may need to enable Less Secure Applications in your Google account settings in order to be able to log in with regular email address and password.

  • Kevin Fenzi: Flock 2019

    Flock time is upon is! This time in lovely Budapest. As always when flock is in europe, it’s a long flight for me, but otherwise travel was uneventfull: Drive 2 hours to PDX, then PDX to AMS, then a short layover for coffee and stoupwaffles and then AMS to BUD, and finally a taxi ride to the hotel.

    The hotel is quite lovely. It’s right next to the danube river and has a nice view. The AC is working nicely too (it’s quite hot outside here right now). After getting into the hotel yesterday and a quick dinner at a very nice place down the road, I managed to sleep for 10+ hours.

  • KNOB attack: Is my Bluetooth device insecure?

    A recent attack against Bluetooth, called KNOB, has been making waves last week. In essence, it allows an attacker to downgrade the security of a Bluetooth so much that it's possible for the attacker to break the encryption key and spy on all the traffic. The attack is so devastating that some have described it as the "stop using bluetooth" flaw.

    This is my attempt at answering my own lingering questions about "can I still use Bluetooth now?" Disclaimer: I'm not an expert in Bluetooth at all, and just base this analysis on my own (limited) knowledge of the protocol, and some articles (including the paper) I read on the topic.

  • Dear sysadmins: Patch Webmin now – zero-day exploit emerges for potential hijack hole in server control panel

    The bug appears to have been revealed on Saturday, August 10, by Özkan Mustafa Akkuş at DEF CON and to have been made available as an exploit in a module for the Metasploit framework. The Webmin maintainers didn't hear about it until Saturday, August 17, when they noticed people discussing the issue on Twitter and Reddit. The CVE was created Thursday, August 15.

    Webmin has about 215,000 installations, according to a Shodan search (account required), and about 13,000 instances of the particularly vulnerable version 1.890.

    [...]

    According to Cooper, the malicious code was introduced into Webmin and Usermin through the project's build infrastructure. "We're still investigating how and when, but the exploitable code has never existed in our GitHub repositories, so we've rebuilt from git source on new infrastructure," he said.

    In an email to The Register, Cooper said the malicious code – which appeared in the Sourceforge repo but not the GitHub repo – was introduced to Webmin on local package build infrastructure before it reached Sourceforge.

JDK 16: What’s coming in Java 16

Although not due to arrive until March 2021, Java Development Kit (JDK) 16 has begun to take shape, with proposed features including concurrent thread-stack processing for garbage collection, support for C++ 14 language features, and an “elastic metaspace” capability to more quickly return unused class metadata memory to the OS. JDK 16 will be the reference implementation of the version of standard Java set to follow JDK 15, which arrived September 15. The six-month release cadence for standard Java would have JDK 16 arriving next March. Read more

  • Software-defined vertical industries: transformation through open source

    What do some of the world’s largest, most regulated, complex, centuries-old industries such as banking, telecommunications, and energy have in common with rapid development, bleeding-edge innovative, creative industries such as the motion pictures industry? They’re all dependent on open source software.  That would be a great answer and correct, but it doesn’t tell the whole story. A complete answer is these industries not only depend on open source, but they’re building open source into the fabric of their R&D and development models. They are all dependent on the speed of innovation that collaborating in open source enables. 

More IBM/Red Hat Leftovers

  • Red Hat OpenShift named as most widely deployed multicloud container platform

    US-based enterprise open source software solution provider Red Hat Inc’s Red Hat OpenShift has been named as the most widely deployed multicloud container platform, boosting powerful development and unified operations experiences across many public and on-premises platforms.

  • Ceph scales to 10 billion objects

    Ceph, the open source integrated file, block and object storage software, can support one billion objects. But can it scale to 10 billion objects and deliver good and predictable performance? Yes, according to Russ Fellows and Mohammad Rabin of the Evaluator Group who set up a Ceph cluster lab and, by using a huge metadata cache, scaled from zero to 10 billion 64KB objects. In their soon-to-be published white paper commissioned by Red Hat, “Massively Scalable Cloud Storage for Cloud Native Applications”, they report that setting up Ceph was complex – without actually using that word. “We found that, because of the many Ceph configuration and deployment options, it is important to consult with an experienced Ceph architect prior to deployment.”

  • What I learned as an engineering intern at Red Hat

    Interning at Red Hat has been one of the most challenging summers of my life, but it's been well worth it. Being an engineering intern working on Red Hat OpenShift's GitOps workflow has forced me to grow and learn more than ever before. My internship position on March 4th. A very short time later, COVID-19 caused companies to cancel their internships all over the United States. Thankfully, Red Hat announced that internships would go on in a virtual format.The Early Talent team made the necessary arrangements to make sure that our experience was impacted as little as possible by this change.

  • Start contributing to open source Call for Code projects

    Jumping into the open source world can be intimidating for the uninitiated. Don’t let fear of the unknown stop you from getting involved in open source. In this blog post, we cover some of the basics you need to know before contributing your first line of code. [...] Now that you understand that basic gist of open source, let’s go a little deeper. While some open source projects are small developer tools that help you accomplish a single task, other open source projects are large, complicated pieces of software that have interconnected parts. In these larger projects, different teams or working groups focus on developing specific parts of the technology, collaborating on the technology, peer reviewing and testing the code, and contributing their changes to the core tech.

  • Build Smart on Kubernetes World Tour: Developers’ path to platform freedom

    Without a doubt, Kubernetes is one of hottest open tech projects today and has been so for many years now. The reason for its durable, not-so-secret success? It’s the ability to containerize code, which frees developers from the constraint of writing code for one platform only and instead gives you the freedom of write-once, deploy-anywhere development. And why is this important? Enterprises know that the fastest route to app modernization depends on the ability to develop solutions that protect current tech investments, which likely run across multiple cloud platforms on and off premises. In other words, success depends on your ability to build solutions once and deploy them across multiple hybrid cloud platforms. Yep, containers tech delivers all of that and more. With that baseline, I’m writing to let you know that when it comes to learning Kubernetes, the IBM Developer advocates team has you completely covered with the Build Smart on Kubernetes World Tour. Since we launched the World Tour back in the fall of 2019, the team has delivered literally hundreds of free hands-on workshops globally to teach developers about the power of Kubernetes. It’s all part of the IBM Developer Way, delivering on our sole mission to teach the world’s developers about open tech through hands-on workshops and supporting content such as blog posts, tutorials, and videos. With the recent launch of new content on the Build Smart on Kubernetes World Tour site, it feels like a good time to provide a quick virtual tour of all that the site offers. Visit the updated site to find more than just upcoming tour events, but also self-paced learning options. You can now choose whether you learn at your own pace by viewing recorded content, register for upcoming live events, or, even better, both. I’m going to review each section to show you the details.
