Didn’t archive.org at some point say they would ignore robots.txt? I wish they would.

Even with PDF/A, rendering fidelity is greatly impacted by the viewing software. Especially if that viewer is based on open source, where only a fraction of the PDF spec is implemented.

The author of that article profoundly misunderstands online advertising. At best, he grossly misinterpreted statements made by his sources.

Google does a really poor job of assessing page speed, especially for sites with a lot of client-side processing. Why would they think shaming sites is a good idea?

Google is getting hammered by Amazon for product-centric searches, while Facebook/Twitter/LinkedIn are eating into their ad share. Bing is also surprisingly resilient, taking big steps with their search targeting capabilities. The

Google just last week announced a drop in profit, so expect more of these types of “optimizations” over the coming months. Over the past 6 months they’ve already increased the font size of SERPs, made their ads look even more similar to org

If you benefit from users visiting your website, then post it there. Quality content on a domain name you own will benefit your site’s overall SEO (expertise, authority, trust). Then tweet it and share it on LinkedIn. Posting it on medium

The root cause is usually poor resource estimates (ie. not spending enough time estimating effort before committing to timelines). Some estimating techniques: https://www.simplilearn.com/project-estimation-techniques-ar...

Perhaps most egregious are companies who profiteer from open source, without contributing back. Amazon comes to mind.

If you’re a manufacturer without a strong brand, it’s incredibly risky selling through Amazon. They will take your sales data to evaluate ROI of building it themselves , and then undercut you. Similar if you’re a retailer. This is why Shopi

Do your homework before the interview and check LinkedIn for promotions. Then ask them about that specifically... why have only x People in the team been promoted in the past few years? Why was Jane Soe promoted to y role? Bonus is if you

PDFium and PDF.js have only implemented a small subset of the spec. Other features they don’t support include certain image compression formats or colour management. It’s really only suitable for the simplest of PDFs...

PDF is a really complex format that Google and Mozilla don’t want to spend a lot of time maintaining. PDFium is an an acceptable rendering engine for simpler PDF files, but doesn’t handle complex files very well (resulting in crashes or ren
