  • openSUSE Tumbleweed – Review of the week 2020/48 – Dominique a.k.a. DimStar (Dim*)

    After last week being filled with problems, this week felt like a ‘relaxing one’ – not that there would be fewer changes incoming, but we could focus on those changes instead of cuddling the infrastructure. And so it comes that we managed to publish 5 snapshots during this week (1119, 1121, 1123, 1124, and 1125).

  • Red Hat Process Automation Manager 7.9 brings Apache Kafka integration and more - Red Hat Developer

    Red Hat Process Automation Manager 7.9 brings bug fixes, performance improvements, and new features for process and case management, business and decision automation, and business optimization. This article introduces you to Process Automation Manager’s out-of-the-box integration with Apache Kafka, revamped business automation management capabilities, and support for multiple decision requirements diagrams (DRDs). I will also guide you through setting up and using the new drools-metric module for analyzing business rules performance, and I’ll briefly touch on Spring Boot integration in Process Automation Manager 7.9.

  • Getting started with Fedora CoreOS

    Fedora CoreOS (FCOS) came from the merging of CoreOS Container Linux and Fedora Atomic Host. It is a minimal and monolithic OS focused on running containerized applications. Security being a first class citizen, FCOS provides automatic updates and comes with SELinux hardening.

    For automatic updates to work well they need to be very robust. The goal being that servers running FCOS won’t break after an update. This is achieved by using different release streams (stable, testing and next). Each stream is released every 2 weeks and content is promoted from one stream to the other (next -> testing -> stable). That way updates landing in the stable stream have had the opportunity to be tested over a long period of time.

  • Slimjet – SparkyLinux

    Slimjet is built on top of the Chromium open-source project on which Google Chrome is also based. It enjoys the same speed and reliablity provided by the underlying blink engine as Google Chrome. However, many additional features and options have been added in Slimjet to make it more powerful, intelligent and customizable than Chrome. In addition to that, Slimjet DOES NOT send any usage statistics back to Google’s server like Google Chrome, which is a growing concern for many Chrome users due to the ubiquitous presence and reach of the advertising empire. Slimjet is compatible with all extensions and plugins designed for Google Chrome available from the Chrome web store.

  • Better handling of cached field results in Writer

    Writer now has much better support for preserving the cached result of fields in documents. This is especially beneficial for Word formats where the input document may have a field result which is not only a cache, but re-calculating the formula would yield a different result, even in Word.

    [...]

    Collabora intends to continue supporting and contributing to LibreOffice, the code is merged so we expect all of this work will be available in TDF’s next release too (7.1).

  • Argus: The Linux Commander – Manila Bulletin

    If you are like me who uses a Mac to manage Linux servers, then you may find this little menu bar tool a little nifty. Argus, currently on version 1.3, is a free download from https://argus-app.net. Argus already supports Big Sur and the new Apple Silicon M1 SoC.

    Installing Argus is just like any other MacOS application — drag and drop. Since this is a monitoring tool for remote Linux servers, you will need to add basic server information so Argus can set it up and gather the data from it. Argus creates an SSH tunnel to the server, so it requires SSH credentials (of course this means that the remote server has SSH properly configured). You can use your username-password pair, but I’d advise that you set up your certificates first to make it more secure (and easier).

    Once you have provided the server information and SSH credentials, Argus will connect to it and start downloading the Argus daemon. Installing the daemon will require root privileges, so make sure that you have sudo access, as your password will be asked during the install.

    Configure all the other remote servers that you wish to monitor through the Preferences pane.

  • Additional Linux Power For SAP Business One

    The migration from ERP/ECC 6.0 to S/4 Hana continues to be one of the main challenges in the SAP community. It is worthwhile to also take a look at SAP Business One on Hana in this context.

    It’s well known that more and more companies of all shapes and sizes are taking the first step towards S/4 Hana or are already operating it. What’s not as well known, however, is that Business One (B1), a solution for smaller and mid-sized companies, has been on a steep growth trajectory for a few years now. Experts put the estimated number of B1 installations at 100,000 worldwide.

  • Master boot vinyl record: It just gives DOS on my IBM PC a warmer, more authentic tone

    Looking for something to do in quarantine? How about booting DOS from a 10-inch vinyl record?

    While booting an operating system nowadays usually sees the software loaded from disk or flash memory, some of us of a certain age recall the delights of shovelling bytes in memory via the medium of tape, such as an audio cassette sending noise into the RAM of a home computer.

    Tinkerer Jozef Bogin has taken things a little further by booting an elderly IBM PC from a record player.

    Bogin used an old IBM PC and took advantage of a boot loader that would cause the hardware to fall back to the PC's cassette interface should everything else (floppies etc) fail. An analogue recording of bootable, read-only RAM drive was played through the interface, containing a version of FreeDOS tweaked by Bogin to fit into the memory constraints, a tiny COMMAND.COM and a patched version of INTERLINK to shovel data through the printer cable.

  • The Homer Car, But It's leinir's Laptop

    We are now into week three of me sitting in a virtual machine on my better half's laptop, while we wait for my replacement Dell XPS 13 2-in-1 (2019) to arrive, after Dell conceded that they could not fix the old one. Short version: The graphics fan went wonky and stopped spinning, so they sent an engineer out to replace the mainboard (because everything is soldered on, including the fan assembly), and then it stopped booting. So they sent out another, and that also immediately failed to post, and then decided that wasn't worth trying again, so they would send me a replacement laptop. Three weeks later, and i have a tracking number, with no updates for a couple of days, though it also isn't past the estimate they gave me for getting it (two weeks for an in stock item, from Ireland to England, nice...).

  • Kafka destination improved with template support in syslog-ng - Blog - syslog-ng Community - syslog-ng Community

    The C implementation of the Kafka destination in syslog-ng has been improved in version 3.30. Support for templates in topic names was added as a result of a Google Summer of Code (GSoC) project. The advantage of the new template support feature is that you no longer have to use a static topic name. For example, you can include the name of your host or the application sending the log in the topic name. From this blog you can learn about a minimal Kafka setup, configuring syslog-ng and testing syslog-ng with Kafka.

  • Algolia Search in Jekyll

    I am relieved and delighted to have finally managed the Algolia search setup for Unix Tutorial. I’ve been looking to upgrade search for a long time but had not enough JavaScript and CSS knownledge to replace the default search with Algolia’s one. I’m going through a short technical course about Vue (JavaScript framework), so this must have put me into the right mindset.

  • Partners Feel ‘Betrayed,’ ‘Taken Aback’ By Microsoft’s Direct Calls To Customers

    A California MSP learned a lesson years ago when a software vendor tried to go direct with his end users. So when Microsoft demanded contact information for his customers, he gave them an email address that went directly to him instead. Earlier this week that email account, which was set up about 18 months ago in the hopes that it would not be used, received a message from a Microsoft business development specialist offering his customer “free training.” “That’s exactly what I would do if I was trying to steal someone else’s business,” said the MSP, who asked not to be named because he fears retribution from Microsoft for speaking out. “It’s just wrong. It’s just wrong. Plain and simple.”

  • Windows 10 bug corrupts your hard drive on seeing this file's icon

    In August 2020, October 2020, and finally this week, infosec researcher Jonas L drew attention to an NTFS vulnerability impacting Windows 10 that has not been fixed. When exploited, this vulnerability can be triggered by a single-line command to instantly corrupt an NTFS-formatted hard drive, with Windows prompting the user to restart their computer to repair the corrupted disk records. The researcher told BleepingComputer that the flaw became exploitable starting around Windows 10 build 1803, the Windows 10 April 2018 Update, and continues to work in the latest version. What's worse is, the vulnerability can be triggered by standard and low privileged user accounts on Windows 10 systems.

  • Open source software security in an ICT context – benefits, risks, and safeguards

    In a recent report, contributors to free and open source software (FOSS) claimed they spent only 2.27 percent of their contribution time on security. In our latest blog post, we delve into open source software security, and discuss why it’s key for building robust and open interoperable networks. [...] Is open source software better than proprietary software when it comes to security vulnerabilities? Elias Levy, the person behind the infamous (vulnerability) full disclosure mailing list, Bugtraq, said two decades ago: “No. Open Source Software certainly does have the potential to be more secure than its closed source counterpart. But make no mistake, simply being open source is no guarantee of security”. Building and delivering complex system software without security vulnerabilities requires investment and due diligence, regardless if the code is open sourced or proprietary (see figure 1, below). As the Mozilla Foundation states: “Security is a process. To have substantial and lasting benefit, we need to invest in education, best practices, and a host of other areas”. Tools and resources are available. With safeguards in place, OSS can be used effectively at low risk to realize its intended benefits. ICT products relying on OSS must be developed using methodologies and safeguards that ensure the expected level of security is met. OSS can accelerate innovation, reduce the development timeline, speed time to market, realize cost savings, and be secure. ICT vendors must take responsibility and practice a higher level of due diligence when using OSS components.

  • Email is the messenger you should migrate to

    But the most important thing: Delta Chat allows you to communicate even with people who don’t use Delta Chat at all, all you need is an email address! If you write to someone without Delta Chat, they will just get a normal email. I would argue that even beats Matrix or XMPP.

    Conclusion: If you are concerned about security when chatting and would rather use a decentralized messenger (no silo), you are in good hands with email and Delta Chat.

  • Looking into Linux user logins with lslogins

    One convenient way to list details about user logins on a Linux system is to use the lslogins command. You'll get a very useful and nicely formatted display that includes quite a few important details. On my system and likely most others, user accounts will start with UID 1000. To list just these accounts rather than include all of the service accounts like daemon, mail and syslog, add the -u option as shown in the example below.
