## mysql – Uncaught Error: Calling the undefined function mysql_connect () – WordPress installation

I tried to install WordPress without xamp on my local computer. Version information:

``````WordPress: 5.2.3
PHP: 7.3.9
Apache: 2.4.41
``````

When accessing this URL -http: // localhost: 8080 / wordpress / wp-admin / install.php, WordPress logs show the following:

``````(16-Sep-2019 18:47:34 UTC) PHP Fatal error:  Uncaught Error: Call to
undefined function mysql_connect() in C:appshttpd-2.4.41-win64-
VS16Apache24htdocswordpresswp-includeswp-db.php:1643
``````

I have tried the solutions available online, but still see the error.

Solutions I've tried so far:

Add the following to my wp-config.php:

``````define( 'WP_USE_EXT_MYSQL', true);
``````

Added the following to php.ini:

``````extension_dir = "ext"
extension=php_mysqli.dll
``````

This is my phpinfo:

## Boot Camp on Windows 10 returns the error code 0xc000021a

My MacBook Pro (Retina, 15 inches, mid 2014) with macOS Mojave version 10.14.6 could not be started in Windows 10 via Boot Camp. I was asked by the Windows Auto Repair system to search for errors. It returns the error code 0xc000021a and claims it wants to restart. After the restart, the entire cycle begins again. This may be because Windows can not be started as on a regular desktop computer. Whenever I want to run Windows, I have to press the Option key and select Run Windows. I tried typing things in a command prompt, but that does not fix the problem. Some commands have suggested that I restart, but if I do, I'll just send back to the automatic repair cycle. I can not start Windows 10 in safe mode because it also requires a reboot. Any ideas or am I better off reinstalling Windows? Thank you so much!

## magento2 – Error 500 on some JS files Magento 2

My theme (Claue from MGS) worked very well.
I have updated my Magento version to 2.3.1, after which some errors have occured which I fixed.

Now I have this problem: My Chrome console generates a 500 error with some JS files, others work fine. In the console with these files say:

jquery-storageapi.js: 1 Resource could not be loaded: The server replied with status 500 (Internal server error)

lazyload.js: 1 resource could not be loaded: the server replied with status 500 (internal server error)

ETC .. There are 14 different JS files

I've tried many thigs (deploy, permission, htaccess, etc), but still can not solve it.

Does anyone have an idea how to solve this?

## statistics – How can I show that the residual error \$ frac { left (Y_1- has {Y} _i right)} { sigma} sim N (0,1) \$ for simple linear regression.

I am working on a simple linear regression with the normal error assumption $$Y_i = beta_0 + beta_1 X_i + epsilon_i$$. $$epsilon_i sim N (0, sigma ^ 2)$$ where the estimated mean answer is $$has {Y} _i = b_0 + b_1 X_i$$ With $$b_0 = bar {Y} -b_1 bar {X}$$ and $$b_1 = frac { sum limits_i (X_i- bar {X}) (Y_i- bar {Y})} { sum limits_i (X_i- bar {X}) ^ 2}$$,

In deriving the distribution of the quantity $$frac {(b_1- beta_1)} {s (b_1)}$$, Where $$s (b1)$$ is the standard error in $$b_1$$I came across the claim that
$$frac {SSE} { sigma ^ 2 (n-2)} sim frac { chi ^ 2 _ {(n-2)}} {n-2}$$
Where SSE is the sum of the quadratic residual error $$SSE = sum limits_i (Y_i- has {Y} _i) ^ 2$$,

That seems to imply that to me $$frac {Y_i- has {Y} _i} { sigma} sim N (0,1)$$, However, I could not prove the above facts.

Can someone help me to understand why the above quantity is $$chi ^ 2 _ {(n-2)}$$ distributed? THANK YOU SO MUCH!

## python – Sympy library: I have the Intel MKL FATAL ERROR error: The file mkl_intel_thread.dll can not be loaded

I'm really frustrated and can not find a solution, see, I'm trying to use the Python sympy library, but trying to write code so that the graph of a function returns the following error: Intel MKL FATAL ERROR: Unable to load You mkl_intel_thread.dll.

What I do is the following:

``````from sympy import *
x,y,z = symbols("x y z")
print(plot(cos(x)))
``````

After making this code so easy that the graph of cos (x) is displayed
I get the following error in the output:

``````INTEL MKL ERROR: %1 no es una aplicaci¾n Win32 vßlida. mkl_intel_thread.dll.
Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.
``````

Also attached that this error occurs only at the time of the graphical representation, everything else works flawlessly. The only thing I can think of is that the error is due to the processor, because my processor is AMD and the DLL my code editor is trying to do is refer to the cores of an Intel processor.

## Kodi gets stuck on the first screen on the first startup. Obvious database error in the log file

On a freshly installed 64bit Ubuntu 18.04 system with Intel graphics is a freshly installed `kodi` hangs on the welcome screen. The log file will appear nominally up to the last three lines.

``````2019-09-15 08:17:16.734 T:139670001514240  NOTICE: Running database version Addons27
2019-09-15 08:17:16.735 T:139670001514240   ERROR: SQL: (ViewModes6.db) SQLite error SQLITE_ERROR (no such table: version)
Query: SELECT idVersion FROM version
2019-09-15 08:17:16.792 T:139670001514240   ERROR: Process error processing job
``````

I tried `kodi` both of the stock repo and the stable ppa had the same problem.

I have installed `kodi` successful on several systems and AFAIK did not do anything else this time – why is it hanging here?

## HomeBrew error message OSX – Super User

I have the latest brew installed on OSX. When you run the update or install new formulas, you receive the following error message:

Error: The following directories can not be described by your user:
/ usr / local / share / man / man5

You should change ownership of these directories to your user.
sudo chown -R \$ (whoami) / usr / local / share / man / man5

And make sure your user has write permission.
chmod u + w / usr / local / share / man / man5

At the moment, I can not find any information about what this means in the context of brewing. My goal is to understand it and not just make the permission change without understanding the implications or why this directory does not have the correct permission.

Thank you in advance.
