I began writing this article in early July 2023 but began to feel a little underwhelmed by it and so left it unfinished. However, after recent and renewed discussions around the relevance and usefulness of build steps, I decided to dust it off and get it finished. Let’s go! When serving and storing files on the web, there are a number of different things we need to take into consideration in order to balance ergonomics, performance, and effectiveness.

The proliferation of the Internet of Things ( IoT ) has led to an explosion in the number of connected devices, from smart thermostats in homes to sensors in manufacturing plants. As these devices multiply, so does the complexity of managing them. Enter IoT device management — the suite of tools and practices designed to monitor, maintain, and update these interconnected devices.

VMware Aria Operations for Logs (formerly known as vRealize Log Insight) is used across enterprises to collect logs and provide analytics. The company recently announced a high-severity vulnerability in an earlier version of the tool. Tracked as CVE-2023-34051 (CVSS score: 8.1), the Aria Operations for Logs vulnerability relates to a case of authentication bypass that could lead to remote code execution.

While I am heartened to hear that the Executive Order on AI uses the Defense Production Act to compel disclosure of various data from the development of large AI models, these disclosures do not go far enough. The EO seems to be requiring only data on the procedures and results of “Red Teaming” (i.e. adversarial testing to determine a model’s flaws and weak points), and not a wider range of inf

If you wanted to cache a file ‘forever’, you’d probably use a Cache-Control header like this: Cache-Control: max-age=31536000 This instructs any cache that it may store and reuse a response for one year (60 seconds × 60 minutes × 24 hours × 365 days = 31,536,000 seconds ). But why one year? Why not 10 years? Why not max-age=forever ? Why not max-age=∞ ?!

Where this delivers even more value is when you can solve problems by pairing techniques learned on one project with tools learned working on another. It all adds up.

But before discussing why, it’s important to think about what prompt engineering means.

However: They didn’t document this (!) Their implementation doesn’t actually save memory The implementation can have a prohibitively high CPU cost This feature works by limiting the working set of a process – the amount of memory mapped into the address-space of the process – to 32 MiB.

When creating applications that store and analyze large amounts of data, such as time series, log data, or event-storing ones, developing a good and future-proof data model can be a difficult task. Determining the most appropriate data types to store the information depends on various factors, including the required precision of float-point values, the content of the values (such as text), compressibility, and query speed.
