gdb and rr are very useful for navigating a large, unfamiliar C and C++ codebases. Since these languages don't dictate how code is organized, the debugger can be the best tool for guiding you through the relevant code for your problem.
Sometimes identical products trade at different venues, often different products at different venues are highly correlated. HFTs reduce the friction of value transfer between these many different markets. They are, in a sense, building the neurons that make up the global economic central nervous system. It's a natural and healthy market phenomenon. The benefits are systemic, which requires some perspective to appreciate. In the course of a decade or two, HFT has permanently cemented itself into the fabric of the finance.
All this talk about front running is uninformed utter nonsense.
Not an answer to your question, but a few interesting data points nonetheless:
"From @YouGov poll: among Republican voters, 45% approve of the storming of Capitol, 30% think the perpetrators are 'patriots', 52% think Biden is at least partly to blame for it, and 85% think it would be inappropriate to remove Trump from office after this. This is not a fringe."

Your comment is prescient, I think. The race against the clock has begun. If we haven't seen the last of these extremist groups, then they're on the fast track to the crypto underbelly of the internet (whether they realize that or not). I hope the inevitable federal and international crackdown sees wide success before these groups go dark.
I support "this kind of censorship" because I'm not an extremist and don't like extremism, especially the violent kind. I hope even the ISPs get involved if that's what it takes to prevent an insurrection from any expression of extremism.
I may reconsider this position if they ever "come for me"; but frankly, for now, I value stability and longevity for our nation more than its abstract ideals about freedom of speech.
Upvote for this. Sometimes, we have to put away our abstract ideals and concede that, although there may not be a "bright line" at which censorship becomes acceptable, the incitement this week crossed it nonetheless.

By then it's too late, that's kind of the point of that poem.
> I'm pretty sure the way they make money is to flash out orders and see if there is a response for the now unavailable security
No.
Market event A is seen to correlate strongly with market event B. The correlation is so obvious that multiple participants compete to make the B trade first in reaction to A. It's part of having a healthy market, electronic or otherwise.
How much fairer and frictionlessier do they become for every picosecond? Is there a limit to fairness and frictionlessyness?
Arguing about HFT feels like you're questioning people about why they're spending billions on excavating single, individual sand grains and the defense you get is "well, sand is an incredibly important building material. It is used in concrete, and we wouldn't have modern society without it". Sure that's true, but why is it that nobody can tell me how what you're doing is actually necessary for that.
