- Yes. [1] has background, [2] has the implementation (fig 2. pseudocode). Since you understood my comment I trust you can figure out the rest :) it’s a very neat trick.

- There is one more way that is truly lock free. Most lock free implementations relying on atomic compare and swap instructions are not lock free afaik; they have a lock on the cache line in the CPU (in a way you go away from global lock to many distributed locks).
There is one more mechanism that allows implementing ring buffers without having to compare head and tail buffers at all (and doesn’t rely on counters or empty/full flags etc) that piggybacks on the cache consistency protocol
- Imagine having to show your ID demonstrating you’re not subject to the law punishing you for driving a car without a driving license.
- happens frequently in fact when training neural nets on modern hw
- The workaround is for everyone to coordinate , print and mail physical returns. Let IRS have fun with scanning and processing :) enough people do this, IRS would open up digital filing again
- (format t "x = ~6d~%y = ~.8E~%" x y)
- it’s a known effect. Without going into details here, you can calculate first crossing time of a barrier in a stochastic process and observe that often the first crossing time decreases as the volatility increases. From there you can set one barrier at 0 (default) and draw your own conclusion.
- Thanks!
- Planes, finance, military equipment, video games, pharmaceuticals (ever heard of ozempic?)
- You’re forgetting prime brokers financing most of the US financial players on wall street Societe generale BNP paribas UBS+Credit Suisse Deutsche bank
Lets also not forget Ubisoft (French company) making assassins creed etc games
And airbus making planes ?
- I think you’re basically wrong?

- Yep. It’s a classic grift; it even has a name „control fraud”…
Described in depth in „lying for money”
- Now we know that it is indeed possible to rob Fort Knox ! Brilliant plan.
- I think it’s a different paper?

- first, folks need to exit/reduce their positions stealthily without disrupting the market. this takes time; for big positions it is not unusual to be exiting it for more than 6 months
- The new OS that doesn’t exist yet. Linux is starting to show its age, dominated by special interest groups and with the upcoming C+Rust contention it’s a perfect breeding ground for the competitor to enter the scene. Best idea likely not to come from corporate
- Multiple possibilities exist but everything depends on context and the skill set.
One option is to start a consulting business with a group of engineers (essentially a market equivalent of a union but with more legal protections) and start charging very high market rates and nickel-and-dime the client hedge fund style with pass-through fees for everything. Use the knowledge of former jobs’ contracts and undercut on price.
If the skill set is very niche and highly specialized you could even attempt cornering the market by recruiting people away that are still employed and sell back their services through the consulting gig (offer profit share as a sweetener, etc.)
- How did you draw the connection between being babysat and drugs?
I know there is an academic wait-free and lock-free definition but folks use those often incorrectly as a slogan that something is magically better because it’s „lockfree”.
Imagine how _you_ would implement a read-modify-write atomic in the CPU and why E stands for exclusive (sort of like exclusive in a mutex)
