How to Write a Cold Email
I'd think opening a PDF in your browser would be at the same risk-level you associate with going to any random URL. On Firefox at least, I'm pretty sure the built-in PDF viewer is simply JS parsing and rendering the PDF anyway -- nothing with elevated permissions:

PDF Chat with Node.js, OpenAI and ModelFusion
We use Mozilla's PDF.js via the pdfjs-dist NPM module to load pages from a PDF file. The loadPdfPages function reads the PDF file and extracts its content. It returns an array where each object contains the page number and the text of that page.

Microsoft faces antitrust scrutiny from the EU over Teams, Office 365
The problem is that there simply wasn't a better option at the time.
Ogg Vorbis was a novelty at best, and it was the only decently widely adopted open source competitor for any of the items listed that was available at the time.
HTML5 was only just published when Chrome launched. So Flash was at that point the only option available to show a video in the browser (sure, downloading a RealPlayer file was always an option, but it was clunky, creators didn't like people being able to save stuff locally, and was also not open source). Chrome in fact arguably accelerated the process of getting web video open sourced: Google bought On2 in 2010 to get the rights to VP8 (the only decent H.264 competitor available at that point) so they could immediately open source it. The plan was in fact to remove H.264 from Chrome entirely once VP8/VP9 adoption ramped up[1], but that didn’t end up happening.
Flash was integrated into Chrome because people were going to use it anyway, and having Google distribute it at least let them both sandbox it and roll out automatic updates (a massive vector for malware at the time was ads pretending to be Flash updates, which worked because people were just that used to constant Flash security patches, most of which required a full reboot to apply; Chrome fixed both of those issues). Apple are the ones who ultimately dealt the death blow to Flash, and it was really just because Adobe could not optimize it for phone CPUs no matter what they tried (even the few Android releases of Flash that we got were practically unusable). That also further accelerated the adoption of open source HTML5 technologies.
PDF is an open source format, and has been since 2008. While I don't know if pressure from Google is what did it, that wouldn’t surprise me. Regardless, the Chrome PDF reader, PDFium, is open source[2] and Mozilla's equivalent project from 2011, PDF.js, is also open source.[3] Both of these projects replaced the distinctly closed source Adobe Reader plugin that was formerly mandatory for viewing PDFs in the browser.
Chrome is directly responsible for eliminating a lot of proprietary software from mainstream use and replacing it with high-quality open source tools. While they've caused problems in other areas of browser development that are worthy of criticism, Chrome's track record when it comes to open sourcing their tech has been very good.

How to run WebAssembly from your Rust Program
Apache CouchDB belongs to the family of NoSQL databases. It is a document store with a strong focus on replication and reliability. One of the most significant differences between CouchDB and a relational database (besides the absence of tables and schemas) is how you query data. Relational databases allow their users to execute arbitrary and dynamic queries via SQL. Each SQL query may look completely different than the previous one. These dynamic aspects are significant for use cases where you work exploratively with your dataset but don't matter as much in a web context. Additionally, defining an index for a specific table is optional. Most developers will define indices to boost performance, but the database does not require it.

I just turns out you can't always do that in a real codebase. For example see here:
