About Klaus Elk
Klaus was the sole SW-developer on the Dantec 'Cantata' - an instrument that measures on muscles and nerves. He took a bachelor in Marketing but stayed in R&D instead of moving to the 'dark side'.
Going back into Telecom he worked with SDH at NKT Elektronik and later with creating a TCP Offload Engine at IPBlaze. For 15 years he has worked at Brüel & Kjær Sound & Vibration, as R&D Manager for Instrumentation. However, in December 2020 he moved to Lithium Balance to work as R&D Software Manager - working with Battery Management Systems.
In parallel with some of the above, Klaus Elk taught OOP and TCP/IP Networks at the Danish Technical University for 10 years.

Blog postWay back in the old days I did a lot of C++, using first MFC and later also ATL. I clearly remember the intellectual challenges – going from C to C++, learning all the stuff about templates, and trying to live without printf and its siblings. Sometimes it was extremely effective, but at other times …

Blog postIn my previous post I reviewed the book -“The Phoenix Project”. See https://klauselk.com/2020/03/02/the-phoenix-project/. It describes the many good features of the DevOps movement. This movement has now become a full-fledged industry. I see a lot of commercials explaining why I should use this or that DevOps site. “Running your own tool chain has so many …

Blog postI recently read “The Phoenix Project”. I have no commercial interests in it, but would like to recommend it. It is a book about Lean, Agile and in particular DevOps. It is not written like a text-book, but like a novel. It wont win any literature prizes, but it’s quite entertaining – if you have …

Blog postThis post has been “upgraded” to a page where updates will take place – see Wireless Compliance. This blog post discusses what you need to consider in order to become SAR compliant with (especially) FCC and EU regulations for WiFi and Bluetooth. This comes on top of all the usual stuff like EMC, immunity, ESD …

Blog postIntroduction The post has been “upgraded” to a page where updates will take place – WiFi – the letters. People often ask: how fast is my network-connection? The answer is: it depends. It depends on how new and advanced your access point/router and device are. It depends on the distance between your access point and your …

Blog postThis post has been “upgraded” to a page where updates will take place – Ethernet Transmission Delay. The “Ethernet Transmission Delay” of a packet is the time it takes to “clock out” an Ethernet packet (aka “Frame”) on a wire. On short wires and LANs this is by far the largest delay related to the …

Blog postTrade Show and Conference in Copenhagen 2018 You know that you are a grumpy old man when you are invited to a free trade-show and still get annoyed about the fact that the first 4-5 rows in all the presentations are reserved to VIP’s.

Blog postThis post has been “upgraded” to a page where updates will take place – Linux and non-Linux in one system. Back in October 2017 I tested Keil’s “µVision” IDE which is created to develop applications for the modern ARM Cortex M-type CPU’s. This is an IDE tailored for Windows that seemed very competent. However, we now see …

Blog postMany text-book solutions are based on either Linux or Windows. But many of us live in a world where we need to jump back and forth. And sometimes this creates a “the past meets the future” experience. Today’s blog is an example of this. In the Second Edition of my book I mention OpenWRT (see also Table of …

Blog postThis post has been “upgraded” to a page where updates will take place – Python and Scapy.
After some blog-entries in not-so-embedded subjects like Google Cloud Platform and Agile Methods, it is now time to go back into the subject of embedded systems. In IoT, these are always “connected” – or at least they can be. This means network and network testing. In my IoT book I have described how I have had great benefit in using “Scapy”. This is a Python module that allows you to genera3 years ago Read more
You need somehow to interface to this from your application which, by the way, you also need to design. You can get far with frameworks, but can you go all the way? Do you have a well-performing and maintainable solution?
This book aims to guide you through the jungle. SQL Server is chosen as the main RDBMS, while the database-interface design is demonstrated to work with Oracle as well. The real-life sample application is written in C# using classic Windows Forms. However, the main design and database-interface is equally relevant for WPF and ASP.net.
The database framework used is ADO.net. The author works with embedded systems and previously wrote the book “Embedded Software for the IoT”. Creating database-based tools, he faced the challenges described, and refined a pattern
over time.
With a mixture of theory, examples, and well-integrated figures, Embedded Software for the IoT helps the reader understand the details in the technologies behind the devices used in the Internet of Things. It provides an overview of IoT, parameters of designing an embedded system, and good practice concerning code, version control and defect-tracking needed to build and maintain a connected embedded system.
After presenting a discussion on the history of the internet and the word wide web the book introduces modern CPUs and operating systems. The author then delves into an in-depth view of core IoT domains including:
- Wired and wireless networking
- Digital filters
- Security in embedded and networked systems
- Statistical Process Control for Industry 4.0
This book will benefit software developers moving into the embedded realm as well as developers already working with embedded systems.
