I recently updated my Piwigo instance to version 15. Not out of a real need, but rather just because it’s good to stay current with software updates. This is the first time I ran into an issue, which I caused but didn’t expect.
I deactivated and deleted most languages, and I also switched my default from “English [GB]” to “English [US]. A mistake as I later found out.
YAML is used in a wide array of applications, whether in Ansible scripts or elsewhere. In general, it is easier to write YAML than to write correct JSON on your keyboard. If you need to read and parse YAML on your Windows computer, you may find it necessary to install LibYAML to have access to useful functions like yaml_parse().
Uncaught Error: Call to undefined function yaml_parse() in yml2xml.php:5This post will explain how you can add LibYAML to your Windows XAMPP installation. This will also resolve the error in case the function is not yet present on your system. However, this is not limited to XAMPP, as the process is similar if you run a Windows server with PHP.
You might find yourself needing to inspect the OCSP response for a given URL. This tool is excellent and can do exactly that.
Time tracking is a fundamental task in most companies. I used to use Clockify for a few years, primarily for its API access and the native Windows client with the mini counter. However, I frequently encountered issues with the client logging me out, crashing, or syncing incorrectly. By the summer of 2024, I had reached my limit.
ClaudeBot is a web crawler used to download training data for training LLMs (Large Language Models). This bot is operated by Anthropic, the company that runs Claude.ai.
ClaudeBot/1.0; +claudebot@anthropic.comShould you block CaludeBot or limit its access, and how can you do that? Find out more in this article.
There might be times when you want to closely follow updates to a public GitHub repository. I had this use case in June 2024 when following the Swiss NCSC for cyber threat information regarding DDoS attacks.
I solved this problem by setting up an API key and regularly querying the main branch commits. However, this process is unnecessarily complex. A much easier way is to follow a repository as an RSS feed.
In today’s digital marketing world, tracking how ads perform is crucial. Google has been helping advertisers track ad performance using something called GLCID. Recently, Google introduced two new tools called WBRAID and GBRAID. These changes are due to new privacy rules from Apple, and they help advertisers see how effective their ads are without compromising user privacy.
The HTTP Archive format, known as HAR, is a JSON-formatted archive file format used to log a web browser’s interactions with a website.
To save a HAR file in Chrome, open the Developer Console. The HAR file contains everything, including cookies and sessions, which can be considered secrets. Remember to be careful with whom you share this file. This can be useful if a website encounters an error condition. It can be a valuable way to debug rendering issues.
IP intelligence and looking up IP addresses has been a regular task for me for many years. Whether it’s debugging during attacks or monitoring crawler activity on websites, I have utilized various methods. I began using ipapi.co to look up IP addresses because it does not require an API key, making it convenient an it still allows for some bulk processing. This approach was ideal for the volume of lookups I performed in 2021. While this technique is still effective, exploring other options like locally hosted databases may be more appealing if you require a higher quota and performance.
Working on Azure, most application directly interact with Redis. However, for debugging or handling incidents, visibility into Redis and its storage can be beneficial. The Azure portal seems to be constantly adding more features in this area. If this is insufficient, a Redis Client can be beneficial. I personally like this client.
