javascript: why does console log return full function instead of result?

I am new to coding and working on an assignment for the online class I am taking. I need to get the console.log file to return the concatenated string that I created with the function. This is what I have: 

        var makeHslString = function(ih, is, il){
            var hslString = "hsl(" + ih + " " + is + "% " + il + "% )" ;
            return hslString;
     }

    var hslString = (makeHslString) ;

    console.log(hslString) ;

   }

I've been playing all day, so I apologize if there is any odd format / syntax, but it's as close as I've been to what I need so far. It almost works, but console.log returns the full function instead of just the HSL string. I can't understand what I'm doing wrong and it really bothers me because it's so close. The answer is probably something really simple, but I can't seem to figure it out. Thanks in advance!

Recurrence: $ T (n) = 4T (n / 2) + Θ (n ^ 2 / log n) $

Is there a way to solve this recurrence using the master theorem:

$$ T (n) = 4T (n / 2) + Θ (n ^ 2 / log n) $$

node.js – Nodejs cannot log in – error says Can't read & # 39; models & # 39; of undefined properties –

I have inherited a Nodejs / mongodb project, a story left by the developer, the web application worked and no longer works. So I am trying to understand why. I am a PHP developer transitioning to node, mongo, mongoose, express … whatever, but I just started and the help would be really good.

So you live on NGINX server, Linux Debian 9, node 12, Mongo 4, used to have SSL certificate but now expired.

Here is the link: http://plataforma.drsmile.pe/ – I know it is in Spanish.

Just click "Create an account" (below), it will display the input fields once filled out and the error will appear when trying to submit the error.

How to read the server / var / log / secure binary log file?

The file /var/log/secure is the authentication log for my server's operating system. However, it is a binary file and I am using Windows. What is the most suitable way to open this file in Windows?

log: any way to know when nginx stops a request, because uwsgi server ran out of workers

I am having an nginx configuration with a uwsgi server with n workers.

If I make n + 1 requests in parallel, the last request stops until one of the n uwsgi workers finishes handling a request.

I wanted to know if there is any way to identify in nginx (or in uwsgi) how often a request has stalled due to uwsgi worker shortage.

Is it possible to log into Azure AAD with a logical application or function?

Morning people,

My challenge is to provide SSO from a third party app that uses a proprietary login feature, to an authenticated Azure AAD web app.

By clicking on the link the third party app triggers the PUBLICATION of a signed SAML token containing a user ID on the endpoint I need to configure in Azure.

That is the part that is fixed and beyond my control. I need to find a way to authenticate the user from that POST request. I've researched it for a long time and can't seem to find a method for this.

The theoretical Azure endpoint should validate the token, parse the user ID, match this to the relevant AAD account (which we sync with the third party to ensure it exists), and return a session cookie and redirect the URL in response POST, which will then redirect to my Azure web app using the newly created AuthN session.

The question is, is there any Azure feature that can handle this? I researched
OAuth 2.0 implicit grant flow,
OAuth 2.0 authentication code grant,
OAuth 2.0 on behalf of the flow,
OAuth 2.0 grants client credentials.

And these don't seem to be able to create an AAD session for a user without a username and password.

Hope this makes sense. If I am addressing the problem wrong then I am happy to receive criticism. I am very new to Azure!

Does f (n) = Θ (g (log (n)) imply f (n) = Θ (log (g (n)))?

I am learning about algorithmic complexities and I have this statement that I need to prove or disprove: f (n) and g (n) are asymptotically positive functions, if f (n) = Θ (g (log (n)) then f (n) = Θ (log (g (n))).

It is true?

macos – LDAP users in Catalina cannot log in – CRAM-MD5 error in opendirectoryd

I am using Catalina 10.15.4 OSX as client and FreeBSD 12-1 with openldap-sasl-server-2.4.48_1 as Openldap server. I have configured the LDAP server using Direct Utility.

  • I can see LDAP users in the Directory Editor tab;
  • I can use "id user" in the terminal that shows the user, their groups, etc.
  • I can use "dscl localhost -read / Search / Users / user" which shows all user information;
  • I can use "dscacheutil -q user -a name user" which shows all user information;
  • I can change to root in terminal and then "su – user" and it works (I have created the home directory and assigned # / Users / $ uid $;
  • BUT I CANNOT log in with the user.

All users on the network are enabled to log in. I have tried using "ssh user @ localhost" and in the login window. It does not work

Set up debugging with "odutil set log debug" and take a look at the console logs:

opendirectoryd  failed CRAM-MD5 authentication for authzid - '' authcid - '' error 49
opendirectoryd  ODRecordVerifyPassword failed with result ODErrorCredentialsInvalid
opendirectoryd  nw_path_evaluator_start (78C31F06-08D0-4EF9-B584-EB41028A814D IPv6#0d17d740.389 generic, local: IPv6#ef0057ec.49455, indefinite)
    path: unsatisfied (No network route)

On the server, CRAM-MD5 is available. 

supportedSASLMechanisms: SCRAM-SHA-1
supportedSASLMechanisms: SCRAM-SHA-256
supportedSASLMechanisms: DIGEST-MD5
supportedSASLMechanisms: CRAM-MD5

debian – / var / log is displayed incorrectly as 100% of used space

On some of our servers /var/log, which is a separate ext4 partition, shows that 100% of the 4.8G of space is in use. But it actually takes up around 200 million disk space. The application can still write records to the directory. What could be causing this error?

Other information:
Debian version: 9.9
The inodes use 1%
