I want to share my experience sourcing a Mathematica Engineer (Palo Alto) on Reddit, Discord, and a professional forum. I followed advice from Wim Dammans and Erin Mathew, who are experts in this sort of sourcing. Here is what I learned. Mathematica Engineers working outside of Wolfram’s Mathematica are rare primarily because it is expensive and not open-source software (here …

A few days ago, many functions on LinkedIn broke for several hours (you can always – and hopefully will be able to – check on Twitter whether something is going on globally). LinkedIn mostly got it back together to the previous state. This post is about what remains broken. A lot, unfortunately – I don’t think it has been that …

Is Boolean (newly) broken? First, let us make it clear what we mean by the question. There are: Google Boolean search Google search LinkedIn Boolean search LinkedIn search. Out of the four, two are intentionally “broken,” and one is broken due to bugs. One works fine, but produces unexpected numbers – and lists – of results – something that has …

Search Engines like Google index pages on the Surface Web, i.e. (roughly speaking) pages that do not require a login. Not all of those pages are indexed.

Google search strings are often called Boolean Strings. But do you think Google search is Boolean? It is not. Neither is LinkedIn’s, despite what their help says. Both platforms apply semantic algorithms, trying to guess the searcher’s intent; one – successfully, the other – poorly, introducing bugs while at it. Both platforms break the formal Boolean rules.

People join LinkedIn to be visible and be found. …

Happy Halloween! I’ll just leave this here. If anyone can make sense of what LinkedIn Job Search does in the two screenshots below, please get in touch. (As with people search, I have no idea. LinkedIn Developers have started to write code in mysterious ways.) (I doubt there is anything underlying here like in the Google case with quotes. It …

The post reflects my current understanding of how Google works. I hope to share extra detail with you as we do more testing or if we hear more from Google Search people. SUMMARY When you write a search string, Google assesses whether it is: Open-ended (assuming you, the user, require assistance) or Specific, or “restrictive.” Google decides on “restrictive” in …
