Programming/Development: Minicoin, GNU Gengetop and Python

  • Building and testing on multiple platforms – introducing minicoin

    While working with large-scale (thousands of hosts), distributed (globally) systems, one of my favourite, albeit somewhat gruesome, metaphors was that of “servers as cattle” vs “servers as pets”. Pet-servers are those we groom manually, we keep them alive, and we give them nice names by which to remember and call (ie ssh into) them. However, once you are dealing with hundreds of machines, manually managing their configuration is no longer an option. And once you have thousands of machines, something will break all the time, and you need to be able to provision new machines quickly, and automatically, without having to manually follow a list of complicated instructions.

    When working with such systems, we use configuration management systems such as CFEngine, Chef, Puppet, or Ansible, to automate the provisioning and configuration of machines. When working in the cloud, the entire machine definition becomes “infrastructure as code”. With these tools, servers become cattle which – so the rather unvegetarian idea – is simply “taken behind the barn and shot” when it doesn’t behave like it should. We can simply bring a new machine, or an entire environment, up by running the code that defines it. We can use the same code to bring production, development, and testing environments up, and we can look at the code to see exactly what the differences between those environments are. The tooling in this space is fairly complex, but even so there is little focus on developers writing native code targeting multiple platforms.

    For us as developers, the machine we write our code on is most likely a pet. Our primary workstation dying is the stuff for nightmares, and setting up a new machine will probably keep us busy for many days. But this amount of love and care is perhaps not required for those machines that we only need for checking whether our code builds and runs correctly. We don’t need our test machines to be around for a long time, and we want to know exactly how they are set up so that we can compare things. Applying the concepts from cloud computing and systems engineering to this problem lead me (back) to Vagrant, which is a popular tool to manage virtual machines locally and to share development environments.

  • GNU Gengetopt - News: 2.23 released

    New version (2.23) was released. Main changes were in build system, so please report any issues you notice.

  • Abolishing SyntaxError: invalid syntax ...

    Do you remember when you first started programming (possibly with Python) and encountered an error message that completely baffled you? For some reason, perhaps because you were required to complete a formal course or because you were naturally persistent, you didn't let such messages discourage you entirely and you persevered. And now, whenever you see such cryptic error messages, you can almost immediately decipher them and figure out what causes them and fix the problem.

GNU
Linux

Linux system administrators are in high demand these days and many hiring managers say they're having a hard time finding talent to fill their open positions. It's critical, then, for companies seeking skilled admins to hone their recruiting process in order to stay competitive – and this starts with writing an effective job posting.

Unfortunately, many companies aren't hitting the mark. Job postings for sysadmin positions are largely similar; they’re boring and generic, according to New York City-based recruiter Steve Levy.

Development

Hi Folks! You may have already read the recent news about Sourceforge.net
hijacking the GIMP project account to distribute adware/malware.
Previously GIMP used this Sourceforge account to distribute their Windows
installer, but they quit after Sourceforge started tricking users with fake
download buttons which lead to malware rather than GIMP. Then Sourceforge
took over GIMP's account and began distributing a trojan installer which
tries to trick users into installing various malware and adware before
actually installing GIMP.

Slashdot Burying Stories About Slashdot Media Owned SourceForge

Filed under

Development

If you’ve followed any tech news aggregator in the past week, you’ve probably seen the story about how SourceForge is taking over admin accounts for existing projects and injecting adware in installers for packages like GIMP. For anyone not following the story, SourceForge has a long history of adware laden installers, but they used to be opt-in. It appears that the process is now mandatory for many projects.

People have been wary of SourceForge ever since they added a feature to allow projects to opt-in to adware bundling, but you could at least claim that projects are doing it by choice. But now that SourceForge is clearly being malicious, they’ve wiped out all of the user trust that was built up over sixteen years of operating. No clueful person is going to ever download something from SourceForge again. If search engines start penalizing SourceForge for distributing adware, they won’t even get traffic from people who haven’t seen this story, wiping out basically all of their value.

SourceForge locked in projects of fleeing users, cashed in on malvertising [Updated]

Filed under

Development

The takeover of the SourceForge account for the Windows version of the open-source GIMP image editing tool reported by Ars last week is hardly the first case of the once-pioneering software repository attempting to cash in on open-source projects that have gone inactive or have actually attempted to shut down their SourceForge accounts. Over the past few years, SourceForge (launched by VA Linux Systems in 1999 and now owned by the tech job site company previously known as Dice) has made it a business practice to turn abandoned or inactive projects into platforms for distribution of "bundle-ware" installers.

Despite promises to avoid deceptive advertisements that trick site visitors into downloading unwanted software and malware onto their computers, these malicious ads are legion on projects that have been taken over by SourceForge's anonymous editorial staff. SourceForge's search engine ranking for these projects often makes the site the first link provided to people seeking downloads for code on Google and Bing search results.

And because of SourceForge's policies, it's nearly impossible for open-source projects to get their code removed from the site. SourceForge is, in essence, the Hotel California of code repositories: you can check your project out any time you want, but you can never leave.

  • The State of Enterprise Open Source 2020: Enterprise open source use rises, proprietary software declines

    Last year we set out to determine how IT leaders think about open source, why they choose it and what they intend to do with it in the future. The result was The 2019 State of Enterprise Open Source: A Red Hat Report, and the findings were clear and confirmed what we see happening in the industry. Enterprise open source has become a default choice of IT departments around the world and organizations are using open source in categories that have historically been more associated with proprietary technology. Headed into the second year of the survey, we had a new directive in mind. We wanted to dive deeper into how IT leaders’ intentions and usage have changed. We surveyed 950 IT leaders in four regions. Respondents had to have some familiarity with enterprise open source and have at least 1% Linux installed at their organization. Respondents were not necessarily Red Hat customers and were unaware that Red Hat was the sponsor of this survey. This allowed us to get a more honest and broad view of the true state of enterprise open source.

  • Manage application programming interfaces to drive new revenue for service providers

    Telecommunications service providers have valuable assets that can be exposed, secured, and monetized via API-centric agile integration. They can derive additional value from new assets, developed internally or through partners and third parties and integrated in a similar way with OSS and BSS systems. Service providers can open new revenue paths if they enhance the value they deliver to customers and to their partner- and developer-ecosystems. APIs can help them accomplish this goal. Services that providers can potentially offer with APIs include direct carrier billing, mobile health services, augmented reality, geofencing, IoT applications, and more. Mobile connectivity, for example, is key to powering IoT applications and devices, giving service providers an inside track to provide APIs to access network information for IoT services. In mobile health, APIs can serve as the link between the customer and healthcare partners through the user’s smartphone. Embracing this API-centric approach, service providers can realize increased agility by treating OSS/BSS building blocks as components that can be reused again and again. They may also innovate faster by giving partners controlled access to data and services, expand their ecosystem by improving partner and third-party collaboration, and generate more revenue through new direct and indirect channels.

  • Autostart Tmux Session On Remote System When Logging In Via SSH

    It is always a good practice to run a long running process inside a Tmux session when working with remote systems via SSH. Because, it prevents you from losing the control of the running process when the network connection suddenly drops. Just in case the network connection gets dropped for any reason, the processes inside the Tmux session will keep running on the remote systems, so you can re-attach to the Tmux session using “tmux attach” command once the network connection is back online. What if you forgot to start the Tmux session in the first place? No matter how careful you’re, sometimes you may forget to start Tmux session. Here is a simple way to avoid this problem. You can autostart Tmux session on the remote systems when logging via SSH. This is especially helpful if you lost the network connection when upgrading a remote Linux server via SSH from your local system.

  • Part 1: How to Enable Hardware Accelerators on OpenShift

    Managing hardware accelerator cards like GPUs or high-performance NICs in Kubernetes is hard. The special payload (driver, device-plugin, monitoring stack deployment and advanced feature discovery), updates and upgrades, are tedious and error-prone tasks, and often third-party vendor knowledge is needed to accomplish these steps. The Special Resource Operator (SRO) is a template for exposing and managing accelerator cards in a Kubernetes cluster. It handles the hardware seamlessly from bootstrapping to update and upgrades fully managed. The first part will describe the SRO in general where the second part will describe the building blocks in SRO and how to enable a different hardware accelerator step by step.

  • Everthing you need to know about tmux – Windows

    What are tmux Windows? tmux window is the entity that holds panes and resides within the tmux session. Think of a window in tmux as a tab in your notebook. Tabs (windows) help organize your work and group your individual pages (panes) based on some topic of your choice. By default, when tmux starts, a session is initialized. Within this session, tmux initializes a single window (by default) which occupies the entire area of the terminal. This window will contain one single pane (by default).
