kandi X-RAY | Perfect Summary
Perfect operates using either a standalone HTTP server, HTTPS server, or through FastCGI server. It provides a system for loading your Swift-based modules at startup, for interfacing those modules with its request/response objects, or to the built-in Mustache template processing system. Perfect is built on a completely asynchronous, high-performance networking engine to provide a scalable option for internet services. It supports Secure Sockets Layer (SSL) encryption, and it features a suite of tools commonly required by internet servers such as WebSockets and iOS push notifications, but you are not limited to those options. Feel free to use your favourite JSON or templating systems, etc.

QUESTION
Here's an example of what I mean:
...ANSWER
Answered 2021-Dec-16 at 10:38foo = 5 creates a local variable inside your function. def foo creates a global variable. That's why they can both have the same name.
If you refer to foo inside your foo() function, you're referring to the local variable. If you refer to foo outside that function, you're referring to the global variable.
Since it evidently causes confusion for people trying to follow the code, you probably shouldn't do this.
QUESTION
I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json dependencies for any git:// URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:
QUESTION
Is it possible to perfectly forward *this object inside member functions? If yes, then how can we do it? If no, then why not, and what alternatives do we have to achieve the same effect.
Please see the code snippet below to understand the question better.
...ANSWER
Answered 2022-Mar-04 at 17:44This is not possible in C++11 without overloading sum for & and && qualifiers. (In which case you can determine the value category from the qualifier of the particular overload.)
*this is, just like the result of any indirection, a lvalue, and is also what an implicit member function call is called on.
This will be fixed in C++23 via introduction of an explicit object parameter for which usual forwarding can be applied: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p0847r7.html
QUESTION
I have a Python 3 application running on CentOS Linux 7.7 executing SSH commands against remote hosts. It works properly but today I encountered an odd error executing a command against a "new" remote server (server based on RHEL 6.10):
encountered RSA key, expected OPENSSH key
Executing the same command from the system shell (using the same private key of course) works perfectly fine.
On the remote server I discovered in /var/log/secure that when SSH connection and commands are issued from the source server with Python (using Paramiko) sshd complains about unsupported public key algorithm:
userauth_pubkey: unsupported public key algorithm: rsa-sha2-512
Note that target servers with higher RHEL/CentOS like 7.x don't encounter the issue.
It seems like Paramiko picks/offers the wrong algorithm when negotiating with the remote server when on the contrary SSH shell performs the negotiation properly in the context of this "old" target server. How to get the Python program to work as expected?
Python code
...ANSWER
Answered 2022-Jan-13 at 14:49Imo, it's a bug in Paramiko. It does not handle correctly absence of server-sig-algs extension on the server side.
Try disabling rsa-sha2-* on Paramiko side altogether:
QUESTION
I've local Swift Packages added to a workspace. They reside in the project subfolders and connected to different git repositories as git submodules. Everything had been working perfectly (the project was able to build, packages were able to resolve, and I could edit the packages within the same workspace).
After I updated Xcode to 13.0, the project started failing to build with multiple errors Missing package product for each local package dependency. Removing derived data, resetting packages, cleaning build folder and restarting Xcode didn't help.
ANSWER
Answered 2021-Sep-22 at 09:42Removing package references from workspace and re-adding them (by simple drag-n-drop from Finder) resolved the problem.
I even didn't need to reconfigure corresponding schemes, or re-adding dependencies in targets.
QUESTION
I am trying to find a more efficient solution to a combinatorics problem than the solution I have already found.
Suppose I have a set of N objects (indexed 0..N-1) and wish to consider each subset of size K (0<=K<=N). There are S=C(N,K) (i.e., "N choose K") such subsets. I wish to map (or "encode") each such subset to a unique integer in the range 0..S-1.
Using N=7 (i.e., indexes are 0..6) and K=4 (S=35) as an example, the following mapping is the goal:
0 1 2 3 --> 0
0 1 2 4 --> 1
...
2 4 5 6 --> 33
3 4 5 6 --> 34
N and K were chosen small for the purposes of illustration. However, in my actual application, C(N,K) is far too large to obtain these mappings from a lookup table. They must be computed on-the-fly.
In the code that follows, combinations_table is a pre-computed two-dimensional array for fast lookup of C(N,K) values.
All code given is compliant with the C++14 standard.
If the objects in a subset are ordered by increasing order of their indexes, the following code will compute that subset's encoding:
...ANSWER
Answered 2021-Oct-21 at 02:18Take a look at the recursive formula for combinations:
Suppose you have a combination space C(n,k). You can divide that space into two subspaces:
C(n-1,k-1)all combinations, where the first element of the original set (of lengthn) is presentC(n-1, k)where first element is not preset
If you have an index X that corresponds to a combination from C(n,k), you can identify whether the first element of your original set belongs to the subset (which corresponds to X), if you check whether X belongs to either subspace:
X < C(n-1, k-1): belongsX >= C(n-1, k-1): doesn't belong
Then you can recursively apply the same approach for C(n-1, ...) and so on, until you've found the answer for all n elements of the original set.
Python code to illustrate this approach:

I am trying to make an HTTP POST request with the flutter plugin HTTP but I am getting an error of the title. Does anyone know the cause of this since in my other applications this works just perfectly fine?
...ANSWER
Answered 2021-May-08 at 22:09To improve compile-time type safety, package:http 0.13.0 introduced breaking changes that made all functions that previously accepted Uris or Strings now accept only Uris instead. You will need to explicitly use Uri.parse to create Uris from Strings. (package:http formerly called that internally for you.)
http.get(someString)
http.get(Uri.parse(someString))
http.post(someString)
http.post(Uri.parse(someString))
(and so on.)
In your specific example, you will need to use:

Desired outcome of a starting state showing 1% left aligned:
Desired outcome of halfway sate with center block perfectly in the middle at 50%:
