grep large binary files Updated 2025-07-16
This is a weak point of grep, it can't handle large lines that don't fit fully into memory:

Grinding for software interviews Updated 2025-07-16
If your kids are about to starve, fine, do it.
But otherwise, Ciro Santilli will not, ever, spend his time drilling programmer competition problems to join a company, life is too short for that.
Life is too short for that. Companies must either notice that you can make amazing open source software projects or contributions, and hire you for that, or they must fuck off.
Group extension problem Updated 2025-07-16
Besides the understandable Wikipedia definition, Video "Simple Groups - Abstract Algebra by Socratica (2018)" gives an understandable one:
Given a finite group and a simple group , find all groups such that is a normal subgroup of and .
We don't really know how to make up larger groups from smaller simple groups, which would complete the classification of finite groups:
In particular, this is hard because you can't just take the direct product of groups to retrieve the original group: Section "Relationship between the quotient group and direct products".
Group homomorphism Updated 2025-07-16
Like isomorphism, but does not have to be one-to-one: multiple different inputs can have the same output.
This brings us to the key intuition about group homomorphisms: they are a way to split out a larger group into smaller groups that retains a subset of the original structure.
As shown by the fundamental theorem on homomorphisms, each group homomorphism is fully characterized by a normal subgroup of the domain.
Bilinear map Updated 2025-07-16
Linear map of two variables.
More formally, given 3 vector spaces X, Y, Z over a single field, a bilinear map is a function from:that is linear on the first two arguments from X and Y, i.e.:Note that the definition only makes sense if all three vector spaces are over the same field, because linearity can mix up each of them.
The most important example by far is the dot product from , which is more specifically also a symmetric bilinear form.

Gülen movement Updated 2025-07-16
Ciro Santilli once was at student a hackthon, where he proposed working on OurBigBook.com to others.
The only person who showed interest was a follower of the sect.

The enemy?
You must watch this: Video "Bill Gates vs Steve Jobs by Epic Rap Battles of History (2012)".

Gurdwara Updated 2025-07-16
The first time Ciro Santilli went to one was when an Indian friend of his took him to the one in the North of Paris when they were living there in the first half of the 2010's, the Gurdwara Singh Sabha France.
Much like Islam's Ramadan, Ciro Santilli appreciates this a lot due to due to Ciro Santilli's self perceived compassionate personality and Ciro Santilli's cheapness.

Social inequality Updated 2025-07-16
Ciro Santilli is extremely passionate about this issue, partly due to Ciro Santilli's self perceived compassionate personality.
One of Ciro's most direct experiences with social inequality is described at: São Remo, the favela next to USP.
We have to be careful not to make everyone poorer when trying to reduce inequality.
But as things stand as of 2020, increasing taxes on the very richest, and notably wealth tax, and investing it in free gifted education, seems like a safe bet to achieve any meaningful level of equal opportunity and meritocracy.
Social media feed that forces you to see posts by non-followed Updated 2025-07-16
During the early 2020s, many of the idiotic social media platforms started adding a non optional "feature" of suggesting feed posts by people you don't follow:
It must have been some A/B testing overload that made that decision to try and make things more addictive for everyone. Or perhaps as a way to drive revenue with people paying to cheat the algorithm and boost their posts.
European Union we need you.
Braindumping Updated 2025-07-16
There are two ways:
- manually dumping your brain on media such as notebooks, wikis or videos, i.e. forming a personal knowledge base
- technically using sensors for brain scanning
Yitang Zhang's theorem Updated 2025-07-16
There are infinitely many primes with a neighbor not further apart than 70 million. This was the first such finite bound to be proven, and therefore a major breakthrough.
This implies that for at least one value (or more) below 70 million there are infinitely many repetitions, but we don't know which e.g. we could have infinitely many:or infinitely many:or infinitely many:or infinitely many:but we don't know which of those.
The Prime k-tuple conjecture conjectures that it is all of them.
