kandi X-RAY | stud Summary
stud is a network proxy that terminates TLS/SSL connections and forwards the unencrypted traffic to some backend. It’s designed to handle 10s of thousands of connections efficiently on multicore machines. It follows a process-per-core model; a parent process spawns N children who each accept() on a common socket to distribute connected clients among them. Within each child, asynchronous socket I/O is conducted across the local connections using libev and OpenSSL's nonblocking API. By default, stud has an overhead of ~200KB per connection—it preallocates some buffer space for data in flight between frontend and backend. stud has very few features—it’s designed to be paired with an intelligent backend like haproxy or nginx. It maintains a strict 1:1 connection pattern with this backend handler so that the backend can dictate throttling behavior, maxmium connection behavior, availability of service, etc. stud will optionally write the client IP address as the first few octets (depending on IPv4 or IPv6) to the backend—or provide that information using HAProxy’s PROXY protocol. When used with the PROXY protocol, stud can also transparently pass an existing PROXY header to the cleartext stream. This is especially useful if a TCP proxy is used in front of stud. Using either of these techniques, backends who care about the client IP can still access it even though stud itself appears to be the connected client. Thanks to a contribution from Emeric at Exceliance (the folks behind HAProxy), a special build of stud can be made that utilitizes shared memory to use a common session cache between all child processes. This can speed up large stud deployments by avoiding client renegotiation.

ANSWER
Answered 2022-Mar-30 at 19:45- At the start of the detection loop,
iis already 5, so usings[i]is undefined behavior - In your detection loop,
iis invariant. you are just comparing a name against the last one [except for the UB, of course].
You need two loops to compare all names against one another.
Also, using 5 everywhere is a "magic number". Better to use a #define (e.g. SMAX)

QUESTION
When I use colon in the tag name like in the example below, it ends up in error (there is no problem with tags without the colon).
...ANSWER
Answered 2022-Mar-24 at 17:13Colon is used for namespaces and per "Namespaces in XML" specification, it cannot be used in entity names.
The specification states:
[Definition: A document is namespace-well-formed if it conforms to this specification. ]
It follows that in a namespace-well-formed document:
- All element and attribute names contain either zero or one colon;
- No entity names, processing instruction targets, or notation names contain any colons.
You can use a trick that is to declare "SomeName" as a namespace as it is suggested in this question: xml schema validation error "prefix is not bound".
On the other hand, "Extensible Markup Language" Specification state that:
Note:
The Namespaces in XML Recommendation [XML Names] assigns a meaning to names containing colon characters. Therefore, authors should not use the colon in XML names except for namespace purposes, but XML processors must accept the colon as a name character.
If you change the parser you can get what you want:
QUESTION
I have been assigned a task to maintain a legacy CGI program which adds data to a college database. This program is made up of a single file and is compiled without warnings. The file uses forward declarations as given below.
...ANSWER
Answered 2022-Mar-16 at 07:46I can't understand what is the purpose of the forward declarations of Grade, Subject, Student and lastErrNo?
Abou the enums, the compiler must know the variables before you can use them, since you are using them in the functions forward declarations, the compiler needs to know what those types are.
The reason for the declaration of int lastErrorNo; globally maybe to keep as a global error flag, but since it's redeclared later as static also globally, the code won't compile due to the redeclaration, maybe a typo?
Why not to immediately replace them with their definitions?
You could just define them before you use them instead of forward declaring. It's just a matter of code organization.

I'm just wondering how I can redirect to StudProfile after using the UpStudProf function. After running UpStudProf function, the URL became http://localhost/csms/public/index.php/Home/StudProfile, but it should be http://localhost/Home/StudProfile and is it possible to remove the Controllers name Home on the URL?
ANSWER
Answered 2022-Mar-11 at 10:00... is it possible to remove the Controllers name
Homeon the URL?
When no defined route is found that matches the URI, the system will attempt to match that URI against the controllers and methods as described above. You can disable this automatic matching, and restrict routes to only those defined by you, by setting the
setAutoRoute()option tofalse:
QUESTION
I need to plot a conditional inference tree. I have selected the party::ctree() function. It works on the iris dataset.
...ANSWER
Answered 2022-Feb-17 at 22:40In each node (including the root node), ctree() conducts an independence test for the dependent variable (problem in your random data) and each of the explanatory variables (age, gender, smoker, before, after). It computes the p-value for each of of the tests and selects the explanatory variable with the lowest p-value for splitting. But only if that p-value is significant at a certain significance level (adjusted for testing multiple explanatory variables). In your data this is not the case because, in fact, the dependent variable has been sampled independently from the explanatory ones. Therefore, the algorithm stops and does not split the root node.
Remarks: It is recommended to use the successor package partykit rather than party for fitting ctree(). See also the accompanying vignette("ctree", package = "partykit") for further details.

QUESTION
Having a hard time learning how to push my Git repository to gitlab. Currently getting this error:
ssh: connect to host gitlab.stud.idi.ntnu.no port 22: Connection timed out fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
I (think I) have connected my SSH on the gitlab website. However I did have some issues on that end too, and I'm therefore unsure whether I did everything right. Most notably when asked to enter a passphrase, my cmd would not take any input other than enter, so I guess I don't have one (or one was generated idk.) EDIT: Managed to change my private SSH keys passphrase. When trying to change the public one, it gives bad permissions error.
I have two files in my .ssh folder: "id_ed25519" and "id_ed25519.pub". And on GitLab, my ssh key is registered. But I don't understand whats stopping me from pushing my git testing rep to GitLab...
...ANSWER

This may be your terminal not showing which or how many characters you type your password.
About the SSH timeout: What does GitLab's connection Verification output for your GitLab server (probably ssh -Tvvv git@gitlab.stud.idi.ntnu.no)?
On that page further up, there is also advice on how to set your ~/.ssh/config file. If your GitLab admins configured a different SSH, please ask them for details, or check their documentation for advice.

Answered 2022-Jan-11 at 10:46The structure returned from the AJAX call is an object, not an array. This may be why your research efforts didn't find an answer.
The equivalent JS code to the PHP you've displayed would access the object (and the child objects in its properties) by key and then use a forEach() loop over the stud array, like this:
