It’s very productive. Big ups to its creators

Talking about 6k+ people, i don't think so. I'm good however
2k can't read properly

Hi
MᏫᎻᎯᎷᎷᎬᎠ
Just wanna get an expert point of view
Why do you guys like C++?
MᏫᎻᎯᎷᎷᎬᎠ
No
Liam
Just wanna get an expert point of view
Why do you guys like C++?
'cuz it earns my living...
MᏫᎻᎯᎷᎷᎬᎠ
I just didn't have much experience with other languages
I really do wanna know what makes it very special
Dima
Just wanna get an expert point of view
Why do you guys like C++?
It's the old-school and its like.. really the one clear language between all these dayum pythons and other stuff
Dima
master race syntax tho
Dima
!
MᏫᎻᎯᎷᎷᎬᎠ
It's the old-school and its like.. really the one clear language between all these dayum pythons and other stuff
Like it separates profs from newbies
MᏫᎻᎯᎷᎷᎬᎠ
Right?
Dima
true devs and skids
Dima
lol
MᏫᎻᎯᎷᎷᎬᎠ
Yeah
MᏫᎻᎯᎷᎷᎬᎠ
I can learn python in 5 days at most
Ariana
*1
Ariana
just get documentation and done
MᏫᎻᎯᎷᎷᎬᎠ
But
Regardless of whether it's easy or not
MᏫᎻᎯᎷᎷᎬᎠ
Why C++ by itself is special?
...
C++ supports most "modern" programming techniques while staying completely native
Mat
I can learn python in 5 days at most
You can learn most programming languages in a bunch of days. Different from being good with it
Elnee

Exactly. Easy to start, hard to master.

What do you mean by "native"?
MᏫᎻᎯᎷᎷᎬᎠ

Yeah
I bet once you master C++ perfectly, learning the basic of those other languages is enough to be good with them
Ludovic 'Archivist'
I think he meant compiled to direct machine code
Ludovic 'Archivist'
Yeah
I bet once you master C++ perfectly, learning the basic of those other languages is enough to be good with them
I would not say so, C++ makes you paranoid on thread safety
MᏫᎻᎯᎷᎷᎬᎠ
I think he meant compiled to direct machine code
Maybe
But if that what he means
Then JIT in java do that, right?
Ludovic 'Archivist'
Maybe
But if that what he means
Then JIT in java do that, right?
so Java is not DIRECTLY compiled to machine code
MᏫᎻᎯᎷᎷᎬᎠ
But
MᏫᎻᎯᎷᎷᎬᎠ
I heard JIT is direct compiled
Ludovic 'Archivist'
It is compiled by a compiler that MUST be fast to compile
MᏫᎻᎯᎷᎷᎬᎠ
To machine code
Ludovic 'Archivist'
Java is defined to have more registers than what is actually present on most CPUs
MᏫᎻᎯᎷᎷᎬᎠ
Java is defined to have more registers than what is actually present on most CPUs
Then how does it workd
Especially if its programs are cross-plateform
Ludovic 'Archivist'
It also tend to use the stack quite an enormous bit, pushing and pulling from it
Ludovic 'Archivist'
Then how does it workd
Especially if its programs are cross-plateform
It makes do using the heap
MᏫᎻᎯᎷᎷᎬᎠ
Make sense
MᏫᎻᎯᎷᎷᎬᎠ
Since every object in java are treated as a reference
Ludovic 'Archivist'
Instead of using registers it uses heap!!!
it also uses quite an amount of heap allocations and may block all the threads at some points to perform a garbage collection
Ludovic 'Archivist'
garbage collection is okay when you have like, 1Go of use heap
MᏫᎻᎯᎷᎷᎬᎠ
it also uses quite an amount of heap allocations and may block all the threads at some points to perform a garbage collection
Yeah
Garbage collection comes as priority number 1 in java
Ludovic 'Archivist'
when you climb up to 250Go of used heap, the weight of it starts getting harsher
MᏫᎻᎯᎷᎷᎬᎠ
Since they do wanna get embarrassed
MᏫᎻᎯᎷᎷᎬᎠ
250Go?
Ludovic 'Archivist'
250Go?
That is what you see in for example Apache Cassandra or Apache Hadoop instances
MᏫᎻᎯᎷᎷᎬᎠ
Whatever
Ludovic 'Archivist'
hopefully Cassandra uses a third of that in bloom filters
MᏫᎻᎯᎷᎷᎬᎠ
I don't think it's something related to programming
MᏫᎻᎯᎷᎷᎬᎠ
So I'll forget it
Ludovic 'Archivist'
it is
MᏫᎻᎯᎷᎷᎬᎠ
Tell me about it then
Ludovic 'Archivist'
Cassandra is a Database and Hadoop is a framework for distributed queries on datasets
Ludovic 'Archivist'
tools used for big data mainly
MᏫᎻᎯᎷᎷᎬᎠ
Cassandra is a Database and Hadoop is a framework for distributed queries on datasets
What are distributed queries?
Ludovic 'Archivist'
queries that span on multiple servers
Ludovic 'Archivist'
map reduce is the most common "algorithm" used for that
Ludovic 'Archivist'
Like getting data from a lot servers?
yes, and filtering and executing operations on that data on the server side to leverage for the quantity of data
MᏫᎻᎯᎷᎷᎬᎠ
MᏫᎻᎯᎷᎷᎬᎠ
But the servers must be connected to each other right?
Ludovic 'Archivist'
But the servers must be connected to each other right?
Yes, that is where Hadoop helps, it manages the cluster and abstract it so that you write a query in Java and execute it everywhere
Ludovic 'Archivist'
then you can fetch either a stream of the results or a single data from the whole set of queries depending on your need
MᏫᎻᎯᎷᎷᎬᎠ
Yes, that is where Hadoop helps, it manages the cluster and abstract it so that you write a query in Java and execute it everywhere
Hadoop is a java framework, sad!!!
Ludovic 'Archivist'
As an alternative, there is Spark
MᏫᎻᎯᎷᎷᎬᎠ
MᏫᎻᎯᎷᎷᎬᎠ
So
MᏫᎻᎯᎷᎷᎬᎠ
"Map reduce" algorithm
Is it like std::map xD?
Ludovic 'Archivist'
no, it has no relation to it
MᏫᎻᎯᎷᎷᎬᎠ
Of course
Ludovic 'Archivist'
map is a transformation on a dataset
