QUESTION
I am currently studying algorithms at college and I am curios as what does a seasoned developer uses in its code when said programmer needs to sort something.
C++ uses IntroSort which has an average of Θ(n log(n)) and worst of Θ(n^2).
C# uses QuickSort which has an average of Θ(n log(n)) and worst of Θ(n^2).
Java uses MergeSort which has an average of Θ(n log(n)) and worst of Θ(n log(n)).
Javascript seems like its doing Θ(n log(n)) and the algorithm depends on the browser.
And from a quick read, the majority of languages have a sorting method that has a time complexity of Θ(n log(n)).
Do programmers use the default sorting methods or they implement their own ?
When do they use the default one and when do they implement their own ?
Is Θ(n log(n)) the best time a sorting algorithm can get ?
There are a ton of sorting algorithm, as I am currently finding out in uni.
...ANSWER
Answered 2021-May-15 at 15:01A different sort is practically chosen based upon what it is sorting and where it is sorting it
- whether the data needs to be sorted at all (can all or a subset of the data be inserted in order?)
- how sorted the data is already (does it come in sorted chunks?)
- whether the data needs to be sorted now or how unsorted it can be before it should be sorted (when? cache compaction during off-peak hours?)
- time complexity
- space requirements for the sort
Distributed environments are also extremely relevant in modern software, and causes states where not all of the nodes may be available
This greatly changes how things are or if they are fully sorted (for example data may be sliced up to different nodes, partially sorted, and then referenced by some sort of Cuckoo Hash YT)

QUESTION
I'm looking for an easy and dependency-light way of wrapping a python library to expose it over:
a) The network, either via HTTP or some other custom protocol, it doesn't matter that much, and encryption isn't required. b) The local machine, the main purpose here is to avoid library import overhead, ideally, this would happen via an efficient mechanism ala pipes or shared memory to minimize the number of data copies and [de]serialization.
It seems like it's an easy enough job to just create a class that runs constantly, with e.g. an HTTP interface mirroring the library functionality and returning e.g. pickled objects corresponding to the answers. But getting it to work efficiently and cover various edge-cases seems tedious and I'm wondering if there's a better way to do this, ideally one that's built into python itself.
Ray seems to have some functionality for this using Actors, but it seems rather heavy-weight and prone to fail when being installed, so I'm curios what alternatives exist.
Also, might be too much of a "library question", if you think it's better suited for another stack exchange website please tell me which and I'll remove it from here.
...ANSWER
Answered 2021-Feb-15 at 17:13Your best options are Flask or FASTAPi. Both are lightweight and very resilient web frameworks, that are also pretty easy to start working with (it may be a matter of adding one decorator to your function to achieve your goal). You may also couple your API with Swagger UI, to have visual interaction with your API resources.
P.S. Ray actors has nothing to do with your request (they are simply statefull objects meant to be run/used in a distributed fashion).
QUESTION
I'm really curios if that somehow a design gap in TypeScript. Let's say I have a function, that takes any objects that fulfills this interface
...ANSWER
Answered 2021-Mar-01 at 08:39genericFunction expects type with index signature.
Foo does not have index signature by the default because it is an interface.
But there is a small hint. If you use type keyword to declare Foo instead of interface - it will work.
Why?
Because type's have index signature by the default.
See this answer.
So, next code will compile:

The question sprang up from reading the answers to this recent post.

...ANSWER
Answered 2021-Jan-24 at 07:18What parseInt does is:
The parseInt() function parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems).
If the argument is not a string to begin with, it gets converted into a string.
When a large number is converted into a string, it starts with the most significant digit, followed by a . and eventually e:
QUESTION
There are services calling service A (10 replicas) via GRpc (100+ req/sec), java generated stubs. We don't have load balancers but I am curios what is the best practice in both cases.
Should clients build the channel on each call to service A or Should I create the managedChannel once until the app shutsdown?
If I create one for each request, calls distributes along 10 replicas but if I create only on application starts all calls goes to the same service
Areplica.On the other hand if I create on each call wouldn't there be thousands of connections open until they get idle (which is 30mins by defeault)?
ANSWER
Answered 2021-Jan-19 at 19:59ManagedChannels should be created seldom and reused heavily. When a ManagedChannel will no longer be used, shutting it down is essential. Otherwise it will leak.
This is a load balancing question and the answer depends on your load balancing architecture. Based on your description, you are likely using one of two structures:
All backends are exposed in DNS. The client connects directly to the backend. I'll call this "exposed"
There is a TCP load balancer that the client creates a connection to and the balancer extends that connection to a backend. I'll call this "hidden"
For both approaches, having backends set nettyServerBuilder.maxConnectionAge(...) is generally necessary for clients to start using new backends.
In the exposed architecture, you simply need to configure load balancing in the ManagedChannel. This is probably as simple as using managedChannelBuilder.defaultLoadBalancingPolicy("round_robin"). The round_robin policy will make a connection to each IP address returned by DNS and distribute RPCs across the addresses. When a backend disconnects due to maxConnectionAge the client will re-resolve DNS and make a new connection.
In the hidden architecture, if you have many clients where each client is "small" compared to each backend, then maxConnectionAge is sufficient. When a backend disconnects due to maxConnectionAge the client will make a new connection to the load balancer which can choose a new backend.
In the hidden architecture, if you have "big" clients that generate more load than a single backend can handle, then things are harder; the client has no visibility into the number of backends and their state, yet the backends can't manage the load themselves. The easiest thing to do here is to create multiple channels and round-robin over them. In Java you can implement this as a Channel so it is hidden from the majority of your code. When a backend disconnects due to maxConnectionAge that one channel will make a new connection to the load balancer which can choose a new backend. The difficulty with this approach is knowing how many channels to make. The hidden architecture with larger clients benefits a lot from using HTTP load balancing instead of TCP load balancing. Even with HTTP load balancing it may be necessary to use multiple managed channels, in order to balance the load balancer's load.

The objective is to create a boolean array, state, from another boolean array, initial, according to the rules described below.
If initial starts with False, the first and subsequent elements of state will be False. Upon reaching True in initial, state will switch to True.

Answered 2021-Jan-19 at 18:04To begin with, your if/else can be greatly simplified. Notice that any time you get a True element, the value of future elements in the output is toggled.
You can therefore safely always start your loop with the assumption that prior elements were False:

Install curio
You can use curio like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
