I have been reading The Pragmatic Programmer and just finished the Concurrency chapter. At the same time, I found Nick Gavalas’s blog post “parallelizing” php and keeping it simple, which talks about his time at Facebook when they developed the concept BigPipe and pagelets. In his blog, he explains how they parallelized PHP in the only way possible: making multiple requests to the web server. Instead of the main thread processing each pagelet (we call them placeholders in Drupal), they’d make an HTTP request to their application to run that same rendering in a different process. Then they would take the results of that HTTP request and stream it using the BigPipe pattern. The timing was perfect and gave me an idea.

Onyx Boox Palma is an e-reader that looks like a smartphone
Onyx Boox has just done something exciting; they have taken a page from the Hisense playbook and released a dedicated e-reader with the familiar candy bar shape as a smartphone, except it is a dedicated e-reader. You can do phone calls with this unit and talk to people on Facebook Messenger, Whatsapp or WeChat with dual microphones. However, it does not support SIM cards or eSim, and you must be on a WIFI connection to do anything useful. The most significant advantage of the Onyx Boox Palma is carrying an e-reader around with you in your pocket; you can’t do this with the vast majority of e-readers on the market. The Palma is available as a pre-order for $249; when it launches, the price will go up to $279.99.Only a small batch of units are available as a first come, first serve basis and will ship out sometime in August 2023. I don’t really have a use for something like this, but the price is interesting, and if it can indeed do smooth scrolling as they claim, I might actually be interested out of sheer curiosity. It’s kind of like if Apple released an iPod Touch, but with an e-ink display.
