Large language models (LLMs) like ChatGPT have revolutionized the way we approach coding and development. By leveraging vast datasets and advanced algorithms, these models can generate code snippets, functions, and even entire projects. However, there's a critical limitation that often goes unnoticed: LLMs can't validate or test the code they generate. This blog post will explore this limitation and provide a real-world example to illustrate the issue.

The tech world is buzzing with Microsoft's latest announcement of ARM-based Surface notebooks and tablets powered by Qualcomm's Snapdragon X Elite and Plus SoC ARM64 processors. This move signifies a bold step forward for Microsoft, aligning itself with other major PC vendors like Lenovo and Acer, who are also diving into the ARM architecture. However, the big question remains: can these new chips truly rival Apple's established M-series ARM-based silicon line?
The Pitfalls and Potential of AI-Generated Unit Tests in Software Development
In the fast-paced world of software development, efficiency and accuracy are crucial. One area where efficiency can be significantly boosted is in the creation of unit tests. Traditionally, writing unit tests is a meticulous and time-consuming process. However, with the advent of AI, there’s potential to automate and expedite this process. Yet, while AI can offer considerable benefits, there are notable pitfalls that developers need to be aware of, especially when it comes to generating unit tests for potentially buggy code.

As I recently wrote in a previous post about the ESXi virtualization lab setup, we needed to upgrade the host hypervisor from the originally installed 6.5.0 to 6.7 U2. Following the instructions on TinkerTry:
https://tinkertry.com/easy-update-to-latest-esxiThis site outlines simple easy to follow steps for upgrading a vSphere ESXi installation to the latest. However it should be noted that the following command simply did not work for my installation:
esxcli software profile update -p ESXi-6.7.0-20190402001-standard -d
https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xmlThis command simply resulted in the download hanging. Network access to the Internet was not an issue, as:
esxcli software sources profile list --depot=https://hostupdate.vmware.com/
software/VUM/PRODUCTION/main/vmw-depot-index.xmlWorked to display the available updates, just fine, as well as the command
esxcli software profile update -p ESXi-6.7.0-20190402001-standard -d
https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml --dry-runproduced output which indicated that downloading the installation package itself was successful.
We were finally able to upgrade the lab by manually download the update package directly from VMware’s web site:
https://my.vmware.com/en/group/vmware/evalcenter?p=free-esxi6Once downloaded and the file has been uploaded to the host datastore, you can install via the command:
esxcli software profile update -p <profile name> -d <location of ZIP file>
esxcli software profile update -p ESXi-6.7.0-20190402001-standard -d <path to update.zip>The latest update includes mitigations for recent speculative execution side-channel attacks targeting Intel chips.
Virtualization Lab with ESXi hypervisor 6.5.x
This is a bit of a dated post, but I’m going to discuss virtualization lab configuration for development and experimentation using ESXi hypervisor 6.5.x. It’s particular relevant now as I’ve setup a Kubernetes cluster at home to develop some orchestration scripts and cluster architecture design for scalable applications. This is a much cheaper solution that deploying a cluster into a cloud-based provider. The only resource cost is power which comes in at a significantly cheaper expense than the per-hour provisioning costs of a cloud provider.
