So the bosses and general peeps at work never close our door properly.

Finally earning the "engineer" part of our job titles :p!

The team headed to Arby's for lunch today. Our DBA walks up to the counter.

arby's guy: "Hey, what can I get you."
dba: "Hello. Yes, I'd like the largest french dip you are legally allowed to serve me."

Absolutely slayed everyone in-line and at the counter.

Deadass, best quote said by my PM in our sprint planning meeting:
"I'm just going to name this sprint 'sprint arlene1' because she's the loser who didn't make it onto AOL on-time".

Random hardware question if anyone knows: On the various types of hard drives (Spinner, SSD, M.2, etc.) does it require the same amount of energy to read and write a bit? Or do they take a different amount of power. Is this even effectively measurable? If they're the same, what about at the byte level?

Okay, so I am learning Python and I have to say it's a very interesting language but I have some questions about how the language is built under the hood as the documentation I can find by Guido doesn't give away all the secrets.

So for the question I am referencing this documentation:
https://python.org/download/...__

So, what does __new__ actually look like inside? Is there a way to see how python itself implements __new__?

I know that the mechanism for C++ malloc and new are well known definitions within that space, but I am having issues understanding exactly what the default __new__ is doing on the machine level.

The documentation I found is great for explaining how to use and override __new__ but it doesn't show what python does it once you hand off operations back to the system.

Any help is greatly appreciated!

On page 19 of the ethereum yellow paper: http://gavwood.com/paper.pdf it defines the address of a wallet as: A(pr) = Β[96...255](KEC(ECDSAPUBKEY(Pr))), which is the right most 160-bits of the Keccak hash of the public key generated by the private key.

If I expose the public key to the network, do I allow people to impersonate me and sign transactions even though they don't have Tr, Ts, or Tw? My understanding is no, that without those values you can't hash the transaction.

Subsequently, this leads me to wonder if the purpose of the address (besides identifying users) to obscure the public key so that the private key is at a less risk of being reversed? Or can the public key of any address be captured?

If the public key of any address can be identified on the network or off network (without actually being the owner of that key), how do you do that? Are there any resources on how to perform this that are computationally easy?

Questions that are bothering me:
When a function that returns void returns, is any value from the stack frame copied into the register?
Is the return address in the stack frame even allocated, or is it nullptr?
Could a void function theoretically return a value if you hacked one into the frame?
Does the register even know to expect a value from a void function? If so, where is the logic for this and what is difference between a void and non-void function return at the stack frame & register level?
Any good books on this stuff?

Is it possible to record the time a thread spends processing only it's code?

E.g. capture sys.ms in thread A -> A is sliced and thread B runs -> B is sliced -> A comes back and captures current sys.ms. The resulting delta of Anow - Ainit includes the time that B spent on the machine.

Is it possible to account for this and get just the time A spent processing?

Is this doable on any other languages?

If it is or isn't, any documentation or papers explain why is appreciated. Google is flooded with "how to time" questions so I'm not seeing any answer for this.

Okay, so I need some serious help. Can someone explain why anyone would want to use java spring beyond IoC? Half the developers I work with swing Spring around likes it's excaliber, yet when truly pressed why they like it they all say: "because of beans".

Spring is massive, so why just beans? The IoC pattern is extremely robust, so I'm sure there are other secrets to be learned. It has to have some other significant advantage.

I totally understand things like Jax-RS for REST endpoints. I don't think spring is needed for that to work, is it?
