Unix at 50, Tectonic Shifts and Servers

Server
  • Celebrating 50 years of the Unix operating system

    Towards the end of the 1960s, a small group of programmers were embarking upon a project which would transform the face of computing forever.

    Today, Unix powers iOS and Android—its legend begins with a gator and a trio of researchers.

  • To Be Always Surfing On Tectonic Shifts

    If you think about it for a minute, it is amazing that any of the old-time IT suppliers, like IBM and Hewlett Packard, and to a certain extent now Microsoft and Dell, have persisted in the datacenter for decades or, in the case of Big Blue, for more than a century. It is difficult to be constantly adapting to new conditions, but to their great credit, they still do as they world is changing – sometimes tumultuously – both around them and underneath their feet.

    So it is with HPE, which is going through its umpteenth restructuring and refocusing since we entered IT publishing more than three decades ago, this time under the helm of Antonio Neri, its relatively new president and chief executive officer. The current Hewlett Packard is a very different animal than the one that sold proprietary minicomputers and then Unix systems in the 1980s and 1990s, and it is in many ways more of a successor to the systems businesses of Compaq and Digital Equipment, which the company absorbed two decades ago.

  • Cloud providers and telemetry via Qt MQTT

    First, the focus is on getting devices connected to the cloud. Being able to send and receive messages is the prime target. This post will not talk about services, features, or costs by the cloud providers themselves once messages are in the cloud.

    Furthermore, the idea is to only use Qt and/or Qt MQTT to establish a connection. Most, if not all, vendors provide SDKs for either devices or monitoring (web and native) applications. However, using these SDKs extends the amount of additional dependencies, leading to higher requirements for storage and memory.

  • SUSE Enterprise Storage and Veeam go great together

    Whether you’re new to the popular Windows-based backup tool Veeam or an old pro, you know that ever-growing demands on your storage resources are a true challenge. The flexibility of Ceph makes it a good choice for a back-up target, and SUSE Enterprise Storage makes it easy.

Noctua NH-L9a-AM4: A Very Low-Profile AMD Ryzen Cooler

At just 37mm tall, the Noctua NH-L9a-AM4 is one of the shortest yet quite capable CPU heatsink fans we have seen yet for AMD Ryzen processors. When looking for a heatsink with a small stature for an AMD APU mini PC build for HTPC / file storage use-cases (more on that build in the next day or two), the Noctua NH-L9a-AM4 fit the criteria and so I went with that given the success with the many Noctua heatsinks we have used over the years. For those potentially interested in the NH-L9a-AM4 for an AMD APU like the new Ryzen 5 3400G or for lower-end Ryzen CPUs, I ran some benchmarks with this cooler. Read more

    Python has become, go programming language Around the World. From many Software companies to Consumer-based Companies.

  • Code it, ship it, own it with full-service ownership

    Software teams seeking to provide better products and services must focus on faster release cycles. But running reliable systems at ever-increasing speeds presents a big challenge. Software teams can have both quality and speed by adjusting their policies around ongoing service ownership. While on-call plays a large part in this model, advancement in knowledge, more resilient code, increased collaboration, and better practices mean engineers don't have to wake up to a nightmare. This four-part series will delve into the concepts of full-service ownership, psychological safety in transformation, the ethics of accountability, and the impact of ownership on the customer experience.

  • Simple rules of good programming

    Hi guys, I work as a programmer for more than 15 years and was using many different languages, paradigms, frameworks and other shit. And I want to share with you my rules of writing good code. [...] Code review can be as good as it can be bad. You can organize code review only if you have a developer who understand 95% of the code and who can monitor all updates without wasting to much time. In another situation, it will be just time consuming and everyone will hate this. On this part got too many questions so describe this more deeply. Many people think that code review it’s a good way of teaching new guys, or teammates who work on a different part of code. But the main target of code review it’s maintaining code quality, and not teaching. Let’s imagine that your team making code for controlling a cooling system for nuclear reactor, or space rocket engine. And you made huge mistake in very hard logic, and then you are giving this for code review to the new guy. How do you think what would be the risk of an accident? — On my practice more than 70%. A good team is where each person has own role and responsibility for the exact piece of work. If someone wants to understand another piece of code then he goes to a person responsible for it and asks her. Impossible to know everything and better excellent understand a small piece of code than all but on 30%.

  • Hone advanced Bash skills by building Minesweeper

    I am no expert on teaching programming, but when I want to get better at something, I try to find a way to have fun with it. For example, when I wanted to get better at shell scripting, I decided to practice by programming a version of the Minesweeper game in Bash. If you are an experienced Bash programmer and want to hone your skills while having fun, follow along to write your own version of Minesweeper in the terminal. The complete source code is found in this GitHub repository.

  • Intellectual property Law and Coding

    In the world of software, good code is a necessity, and great code can make the difference between a startup succeeding and failing. But how do you protect coding innovations that may be novel or unique? Intellectual property law, or IP law, is the main legalistic framework that can answer many of those questions and more. Any business, and perhaps more crucially, any individual coder, should be aware of their options when it comes to maintaining the rights to their work. Here, we delve into some of the most important things to know about IP law and coding.

LLVM 9.0.0 released

It's my great pleasure to announce that LLVM 9 is now available. Get it here: https://llvm.org/releases/download.html#9.0.0 This release is the result of the LLVM community's work over the past six months (up to trunk r366426 plus commits on the branch). Some highlights include: - Support for asm goto, enabling for example the mainline Linux kernel for x86_64 to build with Clang - The RISCV-V target is no longer experimental, but built by default - Experimental support for C++ for OpenCL as well as many bug fixes, optimizations, and diagnostics improvements.
