2B-Alert Web 2.0 Better Predicts When to Take Caffeine


(See my other Coffee related posts) – I made the following post about 11 months ago on July 28, 2018. I am reposting it now becasue the website had been update. It is now 2B-Alert Web 2.0.

Many of us brew coffee first thing in the morning and begin our daily consumption. The U.S. Army researched the consumption of coffee and found that there is an algorithm we can follow to achieve optimum alertness. The results of the study indicate that people’s performance on an attention task can be improved by up to 64 percent. When the algorithm is followed, caffeine consumption can be reduced by up to 65% while still maintaining elevated levels of performance.

As a result of the research, a web-based tool 2B‐Alert Web has been developed to help predict a person’s alertness based on their sleep time and caffeine consumption.

The study “Caffeine dosing strategies to optimize alertness during sleep loss” was published in the Journal of Sleep Research on May 28, 2018.

I don’t drink coffee intending to enhance my alertness these days. I drink it because I simply like the taste. However, if you are in a position where alertness is essential to your job, this may be something to look into.

The 2B-Alert Web 2.0 web tool per their website will:

This software tool predicts the alertness of an “average” individual as a function of sleep/wake schedule, caffeine consumption, and time of day. Optionally, it also provides optimal caffeine schedules for user-provided periods of desired peak alertness. Specifically, it allows users to manually enter a sleep/wake/peak alertness schedule, as well as caffeine dosing and timing, and displays the corresponding predictions for three different statistics of alertness on the psychomotor vigilance task (PVT). If the user provides the desired period of peak alertness, the system will output the estimated optimal caffeine schedules. The tool predicts alertness for the duration of the given schedule and 48 hours of subsequent total sleep deprivation.

This tool can be used to:

  1. Assess the effect of different sleep/wake schedules and caffeine consumption
  2. Design sleep/wake and caffeine schedules to optimize alertness
  3. Generate hypotheses that can be experimentally tested
  4. Optimize the benefits of caffeine use

Do you need to optimize your coffeine consuption?

Book Review: “The Oppressed”


(See all of my Book Reviews) – “The Oppressed” eBook was published in 2018 and was written by Matt Thomas. This is Mr. Thomas’ second publication. This is the first in his “Wroth Worlds” series.

I received an ARC of this novel through in return for a fair and honest review. I categorize this novel as ‘R’ because it contains scenes of Violence and Mature Language. The story is set in the far future. The primary character is Bryan Howe leader of Free Human Special Forces Detachment 8222.

Earth had been invaded and conquered by the Hetarek. Much of the human population on Earth has been exterminated. The remainder has become Hetarek slaves. A few from Earth escaped the Hetarek and, with the help of the Ahai, have fled to the stars. The Free Human forces have begun to fight back against the Hetarek. They have already taken a few systems, now they have set their sights on Earth.

Howe and his team are inserted on Earth to start building a guerrilla army to rise up and assist in an invasion of Earth. But Howe and his team have a difficult job. Not only do the Hetarek keep a close and ruthless watch on the remaining humans, but the humans consider Howe and his colleagues “Runners’. They are looked down upon because the humans that have survived on Earth feel that they were abandoned. With a generation having passed, it is difficult to recruit survivors to risk everything to support the ‘Runners’.

I thoroughly enjoyed the 11+ hours I spent reading this 375-page science fiction novel. I liked the plot of a conquered Earth being retaken. There is a lot of action and not all of the characters you start out with survive. This is just the beginning of the story of a much longer struggle. The cover art is OK, but I would have preferred something closer to the storyline. I give this novel a 5 out of 5.

Product Announcements PFiddlesoft of Quechee, Vermont has released UI Browser 2.8.1, the “ultimate assistant” for GUI Scripting with AppleScript, and a developer utility for exploring Apple’s Accessibility API.

UI Browser helps you to explore, manipulate, and monitor the user interface of most macOS applications running on your computer. With the push of a button, it also generates AppleScript statements to control any application using GUI Scripting, even applications that are not otherwise scriptable. No other utility provides all of the information you need in order to write scripts using GUI Scripting.

Version 2.8.1 of UI Browser adds a link to our website for purchase of a UI Browser registration key, and it fixes an error that caused UI Browser to crash on launch after the free trial period expired.

* UI Browser’s Target menu now includes Apple’s new Script Menu application in Mojave. The Script Menu application handles the Script menu extra if Script Editor preferences are set to show it in the menu bar.

* UI Browser supports Dark Mode in Mojave.

* UI Browser now uses the current “Highlight color” setting in System Preferences to highlight the target UI element when running in Highlight mode.

* AppleScript statements generated by UI Browser can now be sent to Script Debugger 7 from Late Night Software, as well as Script Editor, Smile and earlier versions of Script Debugger.

* UI Browser implements numerous performance enhancements and a number of minor bug fixes.

Developers can license the PFiddlesoft Frameworks for distribution or use with their own products that use Apple’s Accessibility and Quartz Event Taps technologies. The frameworks may be licensed free of charge for personal use or for distribution or use with a free software product.

A Relic of WWII is Returned


(See my other WWII related posts) – My cousin sent me the link to the Chicago Tribune article “The Canteen” this morning. The photo above is from that article.

The article tells of an American Officer who was severely injured in June of 1944 near Mortain, France. Now 75 years later his children have been contacted by a resident of Mortain with the news that he had found their father’s canteen. If this interests you, go read the full story.

Book Review: “The Darkest Year: The American Home Front 1941-1942”


(See all of my Book Reviews as well as my other WWII related posts) – “The Darkest Year: The American Home Front 1941-1942” eBook was published in 2019 and was written by Willaim K. Klingaman. Mr. Klingaman has published more than 10 books.

I received an ARC of this novel through in return for a fair and honest review. I categorize this novel as ‘G. The book is the story of Americans on the home front in the year following the attack on Perl Harbor. While some of the military engagements are mentioned, the book focuses on what was going on at home.

How did we deal with shortages and rationing? How was the shift from a peacetime economy to full war material production handled? How did these early days of the war affect life in the US?

I enjoyed the 11.5+ hours I spent reading this 371-page non-fiction account of life in 1942 America. While non-fiction, this book was easy to read. It brought out several things I had not been aware of. So many mistakes were made by the military and the administration. I like the selected cover art. I give this novel a 5 out of 5.

A Podcast about Kristallnacht

(See my other Podcasts  and WWII related posts) – A few weeks ago I listed to the Kristallnacht episode of the Stuff You Missed in History Class podcast. I listen to Missed in History on a regular basis. It is one of the many podcasts I subscribe to.

This episode dealt with Kristallnacht, the wave of antisemitic violance that occurred across Germany on November 9-10, 1938. The event was named for the shards of glass left littering the streets of Germany after Jewish homes and businesses were vandalized in more than a thousand cities and towns.
