To make it work in both environments you can combine both conditions:

    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301,NE]

I had a special case for a shared hosting (masterhost), everything was failing except:

      RewriteCond %{HTTP:X-Forwarded-Port} !443
      RewriteRule .* https://%{SERVER_NAME}%{REQUEST_URI} [R=301,L]

I was doing a comparison of Angular and React and decided to try out a performance test to see how fast a large(ish) list would render in both frameworks.

When I got done with my React prototype with some basic currency formating, it was taking ~2 seconds to render on my fast laptop. With Angular it was barely noticeable -- only when I switched to my phone did it have a noticeable lag.

This was very surprising because I was told that React was supposed to beat the pants off of Angular for performance, but it appears that the opposite is true in this case.

I distilled my prototype down to a very simple app to try to isolate the issue: https://github.com/pselden/react-render-test

In this sample, it&#39;s taking almost 200ms to render this simple list after changing the language, and I&#39;m barely doing anything.

Am I doing something wrong here?

React vs Angular: Slow rendering with React

I have a big amount of files and parser. What I Have to do is strip all non utf-8 symbols and put data in mongodb. 
Currently I have code like this. 

    with open(fname, &quot;r&quot;) as fp:
        for line in fp:
            line = line.strip()
            line = line.decode(&#39;utf-8&#39;, &#39;ignore&#39;)
            line = line.encode(&#39;utf-8&#39;, &#39;ignore&#39;)

somehow I still get an error

    bson.errors.InvalidStringData: strings in documents must be valid UTF-8: 
    1/b62010montecassianomcir\xe2\x86\x90ta0\xe2\x86\x90008923304320733/290066010401040101506055soccorin

 
I don&#39;t get it. Is there some simple way to do it? 


**UPD**: seems like Python and Mongo don&#39;t agree about definition of Utf-8 Valid string.

I&#39;ve had to update my .htaccess from this:

    RewriteCond %{HTTPS} !=on
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

to this:

    RewriteCond %{HTTP:X-Forwarded-Proto} !https
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

to get it working behind an AWS Elasic Load Balancer. 

It all seems to work fine on AWS, but in my local environment I&#39;m stuck in a redirect loop. 

How I can get this setup to work correctly in both environments?

I&#39;m trying to find documents where a field starts with a value.

Table scans are disabled using [notablescan][1].

This works:

    db.articles.find({&quot;url&quot; : { $regex : /^http/ }})

This doesn&#39;t:

    db.articles.find({&quot;source.homeUrl&quot; : { $regex : /^http/ }})

I get the error:

    error: { &quot;$err&quot; : &quot;table scans not allowed:moreover.articles&quot;, &quot;code&quot; : 10111 }

There are indexes on both `url` and `source.homeUrl`:

    {
    	&quot;v&quot; : 1,
    	&quot;key&quot; : {
    		&quot;url&quot; : 1
    	},
    	&quot;ns&quot; : &quot;mydb.articles&quot;,
    	&quot;name&quot; : &quot;url_1&quot;
    }
    
    {
    	&quot;v&quot; : 1,
    	&quot;key&quot; : {
    		&quot;source.homeUrl&quot; : 1
    	},
    	&quot;ns&quot; : &quot;mydb.articles&quot;,
    	&quot;name&quot; : &quot;source.homeUrl_1&quot;,
    	&quot;background&quot; : true
    }

Are there any limitations with regex queries on subdocument indexes?

  [1]: http://docs.mongodb.org/manual/reference/parameters/#param.notablescan

Can I do a MongoDB &quot;starts with&quot; query on an indexed subdocument field?

    string = c(&quot;apple&quot;, &quot;apples&quot;, &quot;applez&quot;)
    grep(&quot;apple&quot;, string)

This would give me the index for all three elements in `string`. But I want an exact match on the word &quot;apple&quot; (i.e I just want `grep()` to return index 1).  

How to use grep()/gsub() to find exact match

I have the following problem retrieving data from MongoDB using mongoose.

Here is my Schema:


    const BookSchema = new Schema(
    	{
    		_id:Number,
    		title:String,
    		authors:[String],
    		subjects:[String]	
    	}
    );


as you can see i have 2 arrays embedded in the object, let&#39;s say the content of the authors can be something like this: authors:[&quot;Alex Ferguson&quot;, &quot;Didier Drogba&quot;, &quot;Cristiano Ronaldo&quot;, &quot;Alex&quot;]  
what I&#39;m trying to achieve is get all the Alex in the array.

So far, I&#39;ve been able to get the values if they match the value completely. However if I try to get the ones containing Alex the answer is always [].

What I want to know is how I can do this using find() without performing a map-reduce to create a view or a collection and then applying find() over that.

The code here works for exact matches


    Book.find( {authors:req.query.q} , function(errs, books){
    			if(errs){
    				res.send(errs);	
    			}
    			
    			res.json(books);
    		});

	

I tried some things but no luck 
{authors:{$elemMatch:req.query.q}}
{authors:{$in:[req.query.q]}}

This one gives me an error and on top of that says is very inefficient in another post I found here.
{$where:this.authors.indexOf(req.query.q) != -1}

and I also tried {authors:{$regex:&quot;./*value*/i&quot;}}

The map-reduce works fine, I need to make it work using the other approach to see which one is better?  

Any help is greatly appreciated. I&#39;m sure this is easy, but I&#39;m new with NodeJS and Mongo and I haven&#39;t been able to figure it out on my own.

How to get all the values that contains part of a string using mongoose find?

I have some strings that have a mix of English and none English letters. For example:

    w=&#39;_1991_اف_جي2&#39;

How can I recognize these types of string using Regex or any other fast method in Python?

I prefer not to compare letters of the string one by one with a list of letters, but to do this in one shot and quickly.





Detect strings with non English characters in Python

I am looking for a way to get all of the letters in a string before a : but I have no idea on where to start. Would I use regex? If so how?

    string = &quot;Username: How are you today?&quot;

Can someone show me a example on what I could do?

How would I get everything before a : in a string Python

I have a use case where there will be stream of data coming and I cannot consume it at the same pace and need a buffer. This can be solved using an SNS-SQS queue. I came to know the Kinesis solves the same purpose, so what is the difference? Why should I prefer (or should not prefer) Kinesis? 

Why should I use Amazon Kinesis and not SNS-SQS?

I&#39;ve recently inherited a Rails app that uses S3 for storage of assets. I have transferred all assets to my S3 bucket with no issues. However, when I alter the app to point to the new bucket I get 403 Forbidden Status. 

My S3 bucket is set up with the following settings:

			&quot;Action&quot;: &quot;s3:GetObject&quot;,
			&quot;Resource&quot;: &quot;arn:aws:s3:::bucketname/*&quot;
		}
	 ]
    }

**CORS Configuration**

    &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;

            &lt;AllowedMethod&gt;GET&lt;/AllowedMethod&gt;
            &lt;MaxAgeSeconds&gt;3000&lt;/MaxAgeSeconds&gt;

What else can I do to allow the public to reach these assets?

Amazon S3 bucket returning 403 Forbidden

I need to check if a file exists using AWS SDK. Here is what I&#39;m doing:

	var params = {
		Bucket: config.get(&#39;s3bucket&#39;),
		Key: path
	};

	s3.getSignedUrl(&#39;getObject&#39;, params, callback);

It works but the problem is that when the object doesn&#39;t exists, the callback (with arguments err and url) returns no error, and when I try to access the URL, it says &quot;NoSuchObject&quot;.

Shouldn&#39;t this `getSignedUrl` method return an error object when the object doesn&#39;t exists? How do I determine if the object exists? Do I really need to make a call on the returned URL?


How to determine if object exists AWS S3 Node.JS sdk

For example, I have this code:

    import boto3

    s3 = boto3.resource(&#39;s3&#39;)

    bucket = s3.Bucket(&#39;my-bucket-name&#39;)

    # Does it exist???

How can I easily determine if a Boto 3 S3 bucket resource exists?

How can I delete instance in Amazon EC2. I have terminated the instance but still it was showing in instance list table. I want to know few things related to this

    1: Is there any significant difference b/w Delete and Terminate?
    2: what is the use of terminated instance?
    3: what are the cases at which instance gets terminated?

I&#39;ve been developing a Django web application deployed on an Apache server with WSGI, and everything has been going smoothly. Today, I made some minor changes to my app&#39;s `admin.py` in an attempt to customize the build-in Django Admin interface, and initially made a syntax error (an unclosed parenthesis). This meant that when I touched `wsgi.py` and loaded the code (I have WSGI running in daemon mode on my virtual host), my website was replaced with an Internal Server Error because WSGI stopped when it hit the syntax error.

So I fixed the syntax error, checked that I didn&#39;t have any more with `manage.py check`, and touched `wsgi.py ` to redeploy. But my website still displays an Internal Server Error! Checking the Apache logs, this is what I see:

The first series of errors shows WSGI failing due to the syntax error in my `admin.py`. However, the second series of errors seems to show an error internal to Django: 

    RuntimeError: populate() isn&#39;t reentrant

thrown from the `populate` method of `registry.py`.

Googling this error message returns surprisingly little information, none of it from Django documentation. Apparently, it can sometimes happen if you name an app twice in your `settings.py`, but I&#39;m not doing that. More importantly, I haven&#39;t changed `settings.py` since the point where the website was working fine -- the only thing I changed was `admin.py`. 

I tried reverting all the changes I made, so all my Python code is back in the state it was when the website was working -- and I still get the `populate() isn&#39;t reentrant` error when I try to make WSGI reload the code!

I&#39;ve also tried commenting-out different apps in the INSTALLED_APPS section of `settings.py`, and even with only &#39;django.contrib.staticfiles&#39; enabled the error still happens. Weirdly, I still get the error even if I comment out *all* the apps -- Django throws the error even when it isn&#39;t loading any apps!

Does anyone know what&#39;s going on here? Or any better way for me to debug this error, since the traceback in the Apache log is pretty unhelpful?

Notes: I&#39;m using Django 1.7, Apache 2.2, and Python 2.7. 

Django stops working with RuntimeError: populate() isn&#39;t reentrant

I&#39;m trying to figure out what is the full complete configuration of an httpd setup.  

All the configurations files are scattered in different files (/etc/httpd/conf.d, httpd.conf, various mod configs)  

Is there a way to list the final httpd configuration?  
Like the whole running setup configuration in a single file?

How can I view the complete httpd configuration?

I am sure this question is being asked many times but I am not encounter with a problem. I am using XAMPP where I configure Zend framework.

XAMPP is running on **port 8081** as **80** is being occupied by some Windows process I need to use virtual host for that I configure with following code in `C:/xampp/apache/config/extra/httpd-vhosts.config` (or `C:/xampp/apache/conf/extra/httpd-vhosts.conf` in newer releases).

    &lt;VirtualHost *:80&gt;
	ServerName comm-app.local
	DocumentRoot &quot;C:/xampp/htdocs/CommunicationApp/public&quot;
	SetEnv APPLICATION_ENV &quot;development&quot;
		&lt;Directory &quot;C:/xampp/htdocs/CommunicationApp/public&quot;
			DirectoryIndex index.php
			AllowOverride All
			Order allow,deny
			Allow from all
		&lt;/Directory&gt;
    &lt;/VirtualHost&gt;    

and also update the hosts file with `127.0.0.1 comm-app.local` and try to re-start apache but it is showing error.

how to create virtual host on XAMPP

I&#39;m using XAMPP, and I can start Apache, but, MySQL ([phpMyAdmin][1]) start!

When I start, I get this error;

```lang-none
10:07:49 [Apache] Error: Apache shutdown unexpectedly.
10:07:49 [Apache] This may be due to a blocked port, missing dependencies,

I search on it, and, change the port of Apache in Config -&gt; Service and Port setting. I have;

```lang-none
Service name: Apache 2.4
Main port: 122
SSL port: 444
```

I also uninstall Skype (Windows 8/10/Metro version). Nothing is working. In the *httpd.conf* file I have;

```lang-none
Listen 122
ServerName localhost:122
```

I start it via `apache_start.bat` and get;

```lang-none

XAMPP: Couldn&#39;t start Apache (Windows 10)

I have :

1. Apache 2.4 on port 80 of my server, with *[mod_proxy][1]* and *[mod_proxy_wstunnel][2]* enabled

2. Node.js + `socket.io` on port 3001 of the same server

Accessing `example.com` (with port 80) redirects to 2. thanks to [this method][3] with the following Apache configuration:

    &lt;VirtualHost *:80&gt;
        ServerName example.com
        ProxyPass / http://localhost:3001/
        ProxyPassReverse / http://localhost:3001/
        ProxyPass / ws://localhost:3001/
        ProxyPassReverse / ws://localhost:3001/
    &lt;/VirtualHost&gt;

It works for everything, except the websocket part : `ws://...` are not transmitted like it should by the proxy.

When I access the page on `example.com`, I have:

    Impossible to connect ws://example.com/socket.io/?EIO=3&amp;transport=websocket&amp;sid=n30rqg9AEqZIk5c9AABN.

I&#39;ve just installed a Laravel 5 project on MAMP and my pages are not finding the css files.

This is the link to my css in my app.blade.php file:

    &lt;link href=&quot;/css/app.css&quot; rel=&quot;stylesheet&quot;&gt;

And my .htaccess file has this line:

    RewriteBase /laravel-site/laravel-5-app/public/

In the config folder my app.php file contains this:

    &#39;url&#39; =&gt; &#39;http://localhost:8888/laravel-site/laravel-5-app/public/&#39;,

But when I open up this page: http://localhost:8888/laravel-site/laravel-5-app/public/auth/login and check the developer tools, it is looking for the css file at this location: http://localhost:8888/css/app.css

Just as a side note, if I go to this url: http://localhost:8888/laravel-site/laravel-5-app/public/ I get the correct welcome page.


Laravel 5 not finding css files

I know this is a very popular question but I haven&#39;t been able to find a working solution for Laravel 5. I&#39;ve been trying to migrate from Codeigniter for a long time, but this convoluted installation process keeps putting me off.

I don&#39;t want to run a VM, this just seems awkward when switching between projects.

I don&#39;t want to set my document root to the public folder, this is also awkward when switching between projects.

I&#39;ve tried the .htaccess mod_rewrite method

    &lt;IfModule mod_rewrite.c&gt;
      RewriteEngine On
      RewriteRule ^(.*)$ public/$1 [L]
    &lt;/IfModule&gt;

This just gives me a Laravel NotFoundHttpException in compiled.php line 7610.

When I tried L4 a while ago, I used the method of moving the contents of the public folder into the root. The structure of L5 is quite different and following the same steps completely broke Laravel (the server would only return a blank page).

Is there a decent method of removing &#39;public&#39; in a development environment that:

1. Works with L5
2. Allows me to switch between projects with ease (I&#39;m usually working on 2 or 3 at any one time).

Thanks

Laravel 5 – Remove Public from URL

I have created a simple app using AngularJS. When I tried to host that project in my website http://demo.gaurabdahal.com/recipefinder it shows the following error:

&gt;**Forbidden**
&gt;
&gt;You don&#39;t have permission to access /recipefinder on this server.
Server unable to read htaccess file, denying access to be safe

But if I go to http://demo.gaurabdahal.com/ it displays &quot;access denied&quot; message as expected, that I have printed. But why is it unable to open that AngularJS projects &quot;recipefinder&quot;. If I tried to put a simple HTML app there, it opens just fine.

The same AngularJS project works fine when I host that in github ([http://gaurabdahal.github.io/recipefinder][2])

I can&#39;t understand what&#39;s wrong.

Server unable to read htaccess file, denying access to be safe

I have installed Laravel many times on Windows OS but never had this problem.

However, on Ubuntu 14.04 I am getting a 500 Internal Server Error, and messages like this in my logs:

&gt; [Wed Jul 22 10:20:19.569063 2015] [:error] [pid 1376] [client 127.0.0.1:52636] PHP Fatal error: require(): Failed opening required &#39;/var/www/html/laravel_blog/../bootstrap/autoload.php&#39; (include_path=&#39;.:/usr/share/php:/usr/share/pear&#39;) in /var/www/html/laravel_blog/index.php on line 22

Previously I&#39;ve had problems when mod_rewrite was not installed or set up properly, but I have installed it and it is not working. Changed .htaccess as well from original to this.

        +FollowSymLinks
    RewriteEngine On
    
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

I&#39;ve given access to all my folders and files inside i.e.

&gt; /var/www/html/laravel_project

I have all the necessary extensions needed for Laravel 5+ as well. Is there something left that I didn&#39;t do? 

Getting a 500 Internal Server Error (require() failed opening required path) on Laravel 5+ Ubuntu 14.04

Please, don&#39;t recommend me the [long and very detailed thread][1] with more than 173 upvotes. It didn&#39;t work for me. I have also tried many others ([1][2], [2][3], [3][4], [4][5]). They all give me TOO_MANY_REDIRECTS or error 500. So, here is my issue:

With my current .htaccess, this is what happens:

https://www.dukescasino.com/ - works perfectly

https://dukescasino.com/ - redirects to the above which is great


The two options below loads fine, but it should be redirecting to the https version:

http://www.dukescasino.com/

http://dukescasino.com/

Here is the current .htaccess:

    &lt;IfModule mod_rewrite.c&gt;
    RewriteEngine On
    RewriteBase /
    
    # BEGIN WordPress
    RewriteRule ^index\.php$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.php [L]
    &lt;/IfModule&gt;



I don&#39;t believe it is relevant, but if so, here is the list of current active plugins:

 - Advanced Custom Fields
 - All In One SEO Pack
 - Bop Search Box Item Type For Nav Menus
 - Contact Form 7
 - Disable Comments
 - Google XML Sitemaps
 - Jetpack by WordPress.com
 - Search &amp; Filter
 - Slider WD
 - TablePress
 - UpdraftPlus - Backup/Restore
 - Wordfence Security
 - WPide
 - WP Smush
 - WP Super Cache
