It is awarded to researchers in the field for their work, typically for a body of research that has made significant contributions to mathematical knowledge. The prize is named after the mathematician and philosopher Alfred North Whitehead, and it celebrates the legacy of significant mathematical contributions that influence the field.
OMG, the second half of the game where the world becomes quite open and all backstories are revealed, is one of the best gaming moments ever.
The AMS Distinguished Public Service Award is an honor presented by the American Mathematical Society (AMS) to individuals who have made significant contributions to the public understanding and appreciation of mathematics. This award recognizes efforts that help promote mathematical research, education, and outreach, as well as initiatives that serve the broader community and enhance the role of mathematics in society.
The AMS Centennial Fellowship is a prestigious award offered by the American Mathematical Society (AMS) to support outstanding mathematical scientists early in their careers. Established in 1988 to commemorate the 100th anniversary of the AMS, the fellowship is intended to provide financial support for research and collaboration. Recipients of the fellowship are typically selected based on their research accomplishments, the potential for future contributions to mathematics, and the impact of their proposed projects.

This prestigious award is typically given to individuals who have made significant contributions to the field of statistics through research, application, or teaching. The ASA Gold Medal acknowledges work that has had a lasting and influential impact on the profession and the use of statistical methodologies in various disciplines.
nodejs/sequelize/raw/parallel_select_and_update.js by Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01
Ciro Santilli 37 Updated 2025-07-01 +Created 1970-01-01This example is similar to nodejs/sequelize/raw/parallel_update_async.js, but now we are doing a separate SELECT, later followed by an update:
Although this specific example is useless in itself, as we could just use
UPDATE "MyInt" SET i = i + 1 as in nodejs/sequelize/raw/parallel_update_async.js, which automatically solves any concurrency issue, this kind of code could be required for example if the update was a complex function not suitably implemented in SQL, or if the update depends on some external data source.Sample execution:which does:
node --unhandled-rejections=strict ./parallel_select_and_update.js p 2 10 'READ COMMITTED'- PostgreSQL, see other databases options at SQL example
- 2 threads
- 10 increments on each thread
Another one:this will run SELECT FOR UPDATE rather than just SELECT
node --unhandled-rejections=strict ./parallel_select_and_update.js p 2 10 'READ COMMITTED' 'FOR UPDATE'Observed behaviour under different SQL transaction isolation levels:
READ COMMITTED: fails. Nothing in this case prevents:REPEATABLE READ: works. the manual mentions that if multiple concurrent updates would happen, only the first commit succeeds, and the following ones fail and rollback and retry, therefore preventing the loss of an update.READ COMMITTED+SELECT FOR UPDATE: works. And does not do rollbacks, which probably makes it faster. Withp 10 100,REPEATABLE READwas about 4.2s andREAD COMMITTED+SELECT FOR UPDATE3.2s on Lenovo ThinkPad P51 (2017).SELECT FOR UPDATEshould be enough as mentioned at: www.postgresql.org/docs/13/explicit-locking.html#LOCKING-ROWSFOR UPDATE causes the rows retrieved by the SELECT statement to be locked as though for update. This prevents them from being locked, modified or deleted by other transactions until the current transaction ends. That is, other transactions that attempt UPDATE, DELETE, SELECT FOR UPDATE, SELECT FOR NO KEY UPDATE, SELECT FOR SHARE or SELECT FOR KEY SHARE of these rows will be blocked until the current transaction ends; conversely, SELECT FOR UPDATE will wait for a concurrent transaction that has run any of those commands on the same row, and will then lock and return the updated row (or no row, if the row was deleted). Within a REPEATABLE READ or SERIALIZABLE transaction, however, an error will be thrown if a row to be locked has changed since the transaction started. For further discussion see Section 13.4.
A non-raw version of this example can be seen at: nodejs/sequelize/parallel_select_and_update.js.
Alexander Kuznetsov is a mathematician known for his work in various areas of mathematics, particularly in the fields of algebra, number theory, and mathematical analysis. He has made contributions to the understanding and development of mathematical concepts and has published research in these areas. However, there may be multiple individuals with the same name in the field of mathematics, and without more specific information, it can be difficult to pinpoint a particular mathematician's achievements or areas of focus.
The Frederic Ives Medal is an award bestowed by the Optical Society (OSA) to recognize an individual for outstanding achievement in the field of optics. It is named after Frederic Ives, a prominent American physicist and inventor known for his contributions to color photography and optics. The award honors significant contributions that have advanced the optical sciences, and it is one of the highest honors given by the OSA.
Pinned article: ourbigbook/introduction-to-the-ourbigbook-project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
