Does lean have any equivalent of Haskell's operator sections?
You can do
#check (× nat) int -- int × nat #check (+ 3) 2 #check ((×) nat) int -- nat × int #check ((+) 3) 2
But (3 +)
is a parse error.
Ah so I can do sections only on one side - thanks!

It all started off while at work and talking to a friends girlfriend about our drug experiences. I had decided to ease the weed because I had spent a semester smoking it and it had made me lazy which meant I wasnt applying myself to studying. She suggested trying nitrous oxide, and assured me that it wouldnt effect me for more than a few moments, and wasn't a hard drug where I could get addicted to it.
We left work and borrowed a whipped cream maker and purchased a box of canisters each. She cracked open the first one and offered it to me, but passed to see how she reacts to it first. She inhaled it fast, 2 breaths with no 'recycling of the gas' that happens when using balloons.  Next was my turn, and we put on some cranking music on the stereo. I breathed in slowly the first time and held it for a while. I could feel it building up inside me, a feeling of total relaxation and lack of care for anything happening around me. Second breath took me higher, my hearing started to falter and I could only hear this one small segment of music. I waited and could feel the effect getting intense and slowly start tapering off. I took the 3rd breath (this didnt consist of much) and started to feel good again but not as high as before.
I waited and could feel it wearing off, my hands where shaking.
She suggested on the next round we try 2 canisters in a row. The first canister I cleaned off in two very quick breaths, I started feeling extremely happy. Second canister I took quickly, the first breath made my mind sore, I could feel the music pulsing through my body. I attempted to grab inhale the second breath, my hands where numb and I couldnt coordinate them to release the gas, a couple seconds lately they where working again and I took it, deep and long, holding in the gas for as long as possible, trying to get every atom of gas into my system and making this experience last for as long as possible.
This time I felt the feeling of overwhelming happiness build up, peak and slowly disappear. Amazing, feeling the transition from normal -> good -> awesome -> mind blowing is superb being in such a small time because it can be so clearly felt.
We cleaned off the boxes, and I ached for more. We drove back to the shop (about 20km) and picked up 2 more boxes each. We drove to a local park and prepared for this dose.

First canister went OK, I could feel my self becoming relaxed, second canister my hearing started to turn weird, 3rd canister I started to feel like I was thinking on two planes, the feeling was still boosting. I started to think on 10 planes of thought. 4th canister, I tried to ask her to pass it too me but she was laughing at me. I couldnt make out the words to say. Somehow I managed to signal another hit and I was off. I took the breaths fast this time.
This is when I started feeling normal, I knew i still hadnt peaked but could feel my essence pulling out of my body and floating maybe 3 inches above my head. I was watching myself trying to change the track being played. I could feel it wearing off, but my essence hadnít moved back into my body. I then watched myself signal for a 5th canister, take the breaths and drop the machine. This scared me, it felt I had lost all control in my life - but was happy and didnít really care.
Tingling in my legs began, I couldnít move them, it was like pins and needles except it felt really really good.
I floated back into my body and tried to explain what I had just felt. Everything I said felt like a quote from a movie. Everything I said felt copied and fake, and that was I was doing was only a copy of what I had seen someone else do, nothing I had ever done in my entire life felt like it was my 'own doing' - only a mimic of someone else. No matter how hard I tried to explain this the nitrous was still in effect, and more 'movie quotes' spilled out of my mouth. After a few moments of what felt like total loss of control of my life, I was back to normal.
I explained how I felt to her, and she said that I hadnít been quoting movies and she understood what I had been saying when I was high. Whew!
My second hit of 5 straight canisters, made my mind explode into thought. I was considering everything I had ever done, what it had done to lead me to this point in my life, and what I should do from this moment on. I was considering everything at once and everything fell into place making me feel whole and that my being did have substance that was not just copies of what others had done.
I felt great. Never before have I ever smiled so much from a 5 minute buzz, never! It gave me focus and I never regret having the lost feeling I did on the first hit of 5 canisters.
My experiences with nitrous have always been great, I have introduced it to my friends and they all love it except they never do more than 2 canisters at once.
Another experience I had was when I did 4 canisters. I felt numb, but very calm. I tried explaining it to my freinds around me, but my mouth was so numb everything came out as mumbles. The harder I tried the more I mumbled - a good laugh for them.
Since then I have brought a cracker that uses a balloon, but this does not compare to the whip cream machine. The cracker cannot load the canisters fast enough to let me breath in and get the best buzz.

Warning sound
If you hear a warning sound when you turn on the power or try to shoot, the possible causes are as follows.
- Failed to write to Micro SD card
- Micro SD card full
- Problem with lens attachment
- The temperature inside camera is too high
How to reboot
Press and hold the power button for 8 seconds or more.
How to reset AIR A01 network settings to factory default settings
- Turn off the power.
- Remove the Micro SD card.
- Pull and hold the lens release lever.
- Press and hold the shutter button.
- Press the power button once.
- The LED indicator will turn blue and turn off immediately.
- Turn on the power again.
- The network settings are restored to the factory default settings.
If you reset the network settings of the AIR-A01 using the above procedure, the result will be as follows.
- Wi-Fi SSID is the value on the sticker on the back of the camera (AIR-A01-
Serial Number
)
- Wi-Fi passphrase is the value written on the sticker on the back of the camera (8-digit number)
- Bluetooth local name is "AIR-A01"
- Bluetooth passcode is not used
By resetting, the authentication information for connecting to the camera is set to a value that is easy to guess, so the possibility of being hijacked by others increases.
If you have Olympus OA.Central, which has been discontinued on December 25, 2020, you can change the Bluetooth local name and passcode to any value, but this application does not have the same function due to SDK restrictions.
Please be careful when using a camera with network settings reset in public places.

Ayrton Senna And Michael Schumacher Formula 1 Memorabilia Now Up For Grabs At Online Auction
by News DeskThe debate over who the greatest Formula 1 driver in history will by its very nature never be resolved, but when it comes to a selection of the top drivers to have ever graced the sport, then Michael Schumacher and Ayrton Senna are always at the very top of any shortlist.
Their achievements and on-track exploits have long become the stuff of motorsport legend and any memorabilia from their careers tends to attract a lot of attention. So much so that finding decent collectible items is an increasingly difficult endeavor. Fortunately, RM Sotheby’s will be hosting an online-only auction from 22 November to 2 December in Detroit, Michigan of a fantastic collection of F1 memorabilia, both from these two stars as well as some big names predominantly from the late ’80s through to the early 2000s.
The Memorabilia on offer spans everything from signed helmets, racing gloves, large-scale handmade models and race suits to Formula 1 wings, nose cones and even complete racing engines.
Some of the more notable lots include Ayrton Senna’s signed helmet from 1988 when he won his first world championship in a McLaren Honda (estimated at between $50,000 to $70,000) to Michael Schumacher’s 1996 Ferrari racing suit ($10,000 to $12,000). There are numerous high-quality scale models on offer too, Senna’s 1985 Lotus 97T and Hakkinen’s 1999 McLaren Mercedes MP4/14 stand out in particular. Most are priced between $4000 and $6000.
Rear wings, body covers and nose cones from manufacturers like McLaren Mercedes, Arrows, Jordan Peugeot, Ferrari and Lotus Honda will all be available too; just the thing to mount on the back wall of the TV room. Values range from $1,000 for a set of Mika Häkkinen’s 2001 rear wing endplates to a rather more serious $20,000 for a set of wings off the 1979 Ferrari 312 T4 driven by Gilles Villeneuve and Jody Scheckter.
For those looking for something a bit less pricey, there are numerous prints and smaller model cars starting from around $50. To avoid missing out on your chance to own some of this fascinating collection of Formula 1 memorabilia, be sure to click on the link below and register for the auction.

AIMPLB to seek review of SC verdict in Ayodhya case
The Muslim body refuses alternative 5-acre plot
by PTIThe All India Muslim Personal Law Board (AIMPLB) decided on Sunday that it would file a petition seeking review of the Supreme Court's judgement in the Ayodhya issue.
"The land of the mosque belongs to Allah and under Sharia law, it cannot be given to anybody," AIMPLB secretary Zafaryab Jilani told reporters after a meeting of the board here.
"The board has also categorically refused to take five-acre land in Ayodhya in lieu of the mosque. The board is of the view that there cannot be any alternative to the mosque," he added.
Settling a fractious issue that goes back more than a century, the Supreme Court, in its verdict in the Babri Masjid-Ram Janmabhoomi title case on November 9, said the entire 2.77 acres of disputed land should be handed over to the deity Ram Lalla, who was one of the three litigants in the case.
The five-judge Constitution bench also directed the Centre to allot a five-acre plot to the Sunni Waqf Board in Ayodhya to build a mosque.

The Traffic Summary report provides a percentage breakdown of the amount of TCP traffic going through the system. For details about setting ports to be monitored, see Configuring Monitored Ports.The Steelhead appliance automatically discovers all the ports in the system that have traffic. The discovered port and its label (if one exists) are added to the report. If a label does not exist, an unknown label is added to the discovered port.If you want to change the unknown label to a name representing the port, you must re-add the port with a new label. All statistics for this new port label are preserved from the time the port was discovered.Note: The Traffic Summary report displays a maximum of 16 ports and pie slices for the traffic types comprising more than 0.005 percent of the total traffic (by destination port). When there are more than 16 ports, the report displays 15 individual ports and aggregates the remaining ports into the 16th slice. The 16th slice is always gray. Any ports aggregated into the 16th slice are also gray. Any traffic that comprises less than 0.005 percent of the total is not included in the Traffic Summary report, but is aggregated into the Bandwidth Optimization report.The Traffic Summary report provides this table of statistics that describe data activity for the application and the time period you specify.
How much data reduction has occurred? What was the percentage of the total traffic for each port? The Riverbed system reports on performance for periods up to one month. Due to performance and disk space considerations, the display granularity decreases with time passed since the data was sampled. The Traffic Summary report displays these data granularities:Last 1 hour's worth of data is available at 10-second granularity. Last 1 day's worth of data is available at 5-minute granularity. Last 1 week's worth of data is available at 1-hour granularity. Last 1 month's worth of data is available at 2-hour granularity.
Select a period of Last Minute, Last 5 Minutes, Last Hour, Last Day, Last Week, Last Month, or Custom from the drop-down list.For Custom, enter the Start Time and End Time and click Go. Use the following format: YYYY/MM/DD HH:MM:SSTo refresh the report every 10 seconds, select 10 seconds. To refresh the report every 30 seconds, select 30 seconds. To refresh the report every 60 seconds, select 60 seconds. To turn refresh off, click Off.

An Array is a storage for values. You can access it using indexes or
with its API. On the server side, it's often better to use a List which
is less memory and CPU consuming, unless you really need indexed access.
Copies the range of the array starting at pos up to,
but not including, end. Both pos and end can be
negative to count from the end: -1 is the last item in
the array.

What is stereotype threat? In 1995, Steele and Aronson conducted several experiments that showed Black college students performed subpar compared to White students on tests when race was emphasized. When race was not emphasized however, Black students were able to achieve similar scores to White counterparts students. According to Steele and Aronson, “Stereotype threat refers to being at risk of confirming, as self-characteristic, a negative stereotype about one's group” (Steele & Aronson, 1995). Other examples of stereotype threats include:
As an Asian American, I have yet to feel like I’ve been impacted by stereotype threats. I would imagine it to be pretty difficult for someone who’s affected by stereotype threats to perform to the best of their abilities since they are pressured to do well to prove to everyone otherwise of their stereotypes. That pressure would surely cloud one’s judgment and slows their thinking. This topic is pretty hard for me to relate so I’m not sure what else I can say about even after reading and watching videos about stereotype threats. Some things I could try to help others that suffer from stereotype threats would be avoiding bringing up any sort of group stereotypes in the first place.

Question


CakePHP is simple and easy to install. The minimum requirements are a web server and a copy of CakePHP, that’s it! While this chapter focuses primarily on setting up on Apache (because it’s simple to install and setup), CakePHP will run on a variety of web servers such as nginx, LightHTTPD, or Microsoft IIS.
Note
In both XAMPP and WAMP, the mbstring extension is working by default.
In XAMPP, intl extension is included but you have to uncomment
extension=php_intl.dll
in php.ini and restart the server through
the XAMPP Control Panel.
In WAMP, the intl extension is “activated” by default but not working. To make it work you have to go to php folder (by default) C:\wamp\bin\php\php{version}, copy all the files that looks like icu*.dll and paste them into the apache bin directory C:\wamp\bin\apache\apache{version}\bin. Then restart all services and it should be OK.
While a database engine isn’t required, we imagine that most applications will utilize one. CakePHP supports a variety of database storage engines:
Note
All built-in drivers require PDO. You should make sure you have the correct PDO extensions installed.
Before starting you should make sure that your PHP version is up to date:
php -v
You should have PHP 5.6.0 (CLI) or higher. Your webserver’s PHP version must also be of 5.6.0 or higher, and should be the same version your command line interface (CLI) uses.
CakePHP uses Composer, a dependency management tool, as the officially supported method for installation.
Installing Composer on Linux and macOS
Run the installer script as described in the official Composer documentation and follow the instructions to install Composer.
Execute the following command to move the composer.phar to a directory that is in your path:
mv composer.phar /usr/local/bin/composer
Installing Composer on Windows
For Windows systems, you can download Composer’s Windows installer here. Further instructions for Composer’s Windows installer can be found within the README here.
Now that you’ve downloaded and installed Composer, create a new CakePHP application into my_app_name folder. For this just run the following composer command:
php composer.phar create-project --prefer-dist cakephp/app my_app_name
Or if Composer is installed globally:
composer self-update && composer create-project --prefer-dist cakephp/app my_app_name
Once Composer finishes downloading the application skeleton and the core CakePHP library, you should have a functioning CakePHP application installed via Composer. Be sure to keep the composer.json and composer.lock files with the rest of your source code.
You can now visit the path to where you installed your CakePHP application and see the default home page. To change the content of this page, edit src/Template/Pages/home.ctp.
Although composer is the recommended installation method, there are
pre-installed downloads available on
Github.
Those downloads contain the app skeleton with all vendor packages installed.
Also it includes the composer.phar
so you have everything you need for
further use.
By default this is what your application composer.json looks like:
"require": {
"cakephp/cakephp": "3.5.*"
}
Each time you run php composer.phar update
you will receive patch
releases for this minor version. You can instead change this to ^3.5
to
also receive the latest stable minor releases of the 3.x
branch.
If you want to stay up to date with the latest unreleased changes in CakePHP, designate dev-master as the package version in your application’s composer.json:
"require": {
"cakephp/cakephp": "dev-master"
}
Be aware that this is not recommended, as your application can break when the next major version is released. Additionally, composer does not cache development branches, so it slows down consecutive composer installs/updates.
Another quick way to install CakePHP is Oven. It is a simple PHP script which checks the necessary system requirements, installs the CakePHP application skeleton, and sets up the development environment.
After the installation completes, your CakePHP application is ready to go!
Note
IMPORTANT: This is not a deployment script. It is aimed to help developers install CakePHP for the first time and set up a development environment quickly. Production environments should consider several other factors, like file permissions, virtualhost configuration, etc.
CakePHP uses the tmp directory for a number of different operations.
Model descriptions, cached views, and session information are a few
examples. The logs directory is used to write log files by the default
FileLog
engine.
As such, make sure the directories logs, tmp and all its subdirectories in your CakePHP installation are writable by the web server user. Composer’s installation process makes tmp and its subfolders globally writeable to get things up and running quickly but you can update the permissions for better security and keep them writable only for the web server user.
One common issue is that logs and tmp directories and subdirectories must be writable both by the web server and the command line user. On a UNIX system, if your web server user is different from your command line user, you can run the following commands from your application directory just once in your project to ensure that permissions will be setup properly:
HTTPDUSER=`ps aux | grep -E '[a]pache|[h]ttpd|[_]www|[w]ww-data|[n]ginx' | grep -v root | head -1 | cut -d\ -f1`
setfacl -R -m u:${HTTPDUSER}:rwx tmp
setfacl -R -d -m u:${HTTPDUSER}:rwx tmp
setfacl -R -m u:${HTTPDUSER}:rwx logs
setfacl -R -d -m u:${HTTPDUSER}:rwx logs
In order to use the CakePHP console tools, you need to ensure that
bin/cake
file is executable. On *nix or macOS, you can
execute:
chmod +x bin/cake
On Windows, the .bat file should be executable already. If you are using a Vagrant, or any other virtualized environment, any shared directories need to be shared with execute permissions (Please refer to your virtualized environment’s documentation on how to do this).
If, for whatever reason, you cannot change the permissions of the bin/cake
file, you can run the CakePHP console with:
php bin/cake.php
A development installation is the fastest way to setup CakePHP. In this example, we use CakePHP’s console to run PHP’s built-in web server which will make your application available at http://host:port. From the app directory, execute:
bin/cake server
By default, without any arguments provided, this will serve your application at http://localhost:8765/.
If there is conflict with localhost or port 8765, you can tell the CakePHP console to run the web server on a specific host and/or port utilizing the following arguments:
bin/cake server -H <IP_ADDRESS> -p 5673
This will serve your application at http://<IP_ADDRESS>:5673/.
That’s it! Your CakePHP application is up and running without having to configure a web server.
Warning
The development server should never be used in a production environment. It is only intended as a basic development server.
If you’d prefer to use a real web server, you should be able to move your CakePHP install (including the hidden files) inside your web server’s document root. You should then be able to point your web-browser at the directory you moved the files into and see your application in action.
A production installation is a more flexible way to setup CakePHP. Using this
method allows an entire domain to act as a single CakePHP application. This
example will help you install CakePHP anywhere on your filesystem and make it
available at http://www.example.com. Note that this installation may require the
rights to change the DocumentRoot
on Apache webservers.
After installing your application using one of the methods above into the directory of your choosing - we’ll assume you chose /cake_install - your production setup will look like this on the file system:
/cake_install/
bin/
config/
logs/
plugins/
src/
tests/
tmp/
vendor/
webroot/ (this directory is set as DocumentRoot)
.gitignore
.htaccess
.travis.yml
composer.json
index.php
phpunit.xml.dist
README.md
Developers using Apache should set the DocumentRoot
directive for the domain
to:
DocumentRoot /cake_install/webroot
If your web server is configured correctly, you should now find your CakePHP application accessible at http://www.example.com.
Alright, let’s see CakePHP in action. Depending on which setup you used, you should point your browser to http://example.com/ or http://localhost:8765/. At this point, you’ll be presented with CakePHP’s default home, and a message that tells you the status of your current database connection.
Congratulations!
While CakePHP is built to work with mod_rewrite out of the box–and usually does–we’ve noticed that a few users struggle with getting everything to play nicely on their systems.
Here are a few things you might try to get it running correctly. First look at your httpd.conf. (Make sure you are editing the system httpd.conf rather than a user- or site-specific httpd.conf.)
These files can vary between different distributions and Apache versions. You may also take a look at http://wiki.apache.org/httpd/DistrosDefaultLayout for further information.
Make sure that an .htaccess override is allowed and that AllowOverride is set to All for the correct DocumentRoot. You should see something similar to:
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
<Directory />
Options FollowSymLinks
AllowOverride All
# Order deny,allow
# Deny from all
</Directory>
Make sure you are loading mod_rewrite correctly. You should see something like:
LoadModule rewrite_module libexec/apache2/mod_rewrite.so
In many systems these will be commented out by default, so you may just need to remove the leading # symbols.
After you make changes, restart Apache to make sure the settings are active.
Verify that your .htaccess files are actually in the right directories. Some operating systems treat files that start with ‘.’ as hidden and therefore won’t copy them.
Make sure your copy of CakePHP comes from the downloads section of the site or our Git repository, and has been unpacked correctly, by checking for .htaccess files.
CakePHP app directory (will be copied to the top directory of your application by bake):
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteRule ^$ webroot/ [L]
RewriteRule (.*) webroot/$1 [L]
</IfModule>
CakePHP webroot directory (will be copied to your application’s web root by bake):
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
If your CakePHP site still has problems with mod_rewrite, you might want to
try modifying settings for Virtual Hosts. On Ubuntu, edit the file
/etc/apache2/sites-available/default (location is
distribution-dependent). In this file, ensure that AllowOverride None
is
changed to AllowOverride All
, so you have:
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
<Directory /var/www>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order Allow,Deny
Allow from all
</Directory>
On macOS, another solution is to use the tool virtualhostx to make a Virtual Host to point to your folder.
For many hosting services (GoDaddy, 1and1), your web server is being served from a user directory that already uses mod_rewrite. If you are installing CakePHP into a user directory (http://example.com/~username/cakephp/), or any other URL structure that already utilizes mod_rewrite, you’ll need to add RewriteBase statements to the .htaccess files CakePHP uses (.htaccess, webroot/.htaccess).
This can be added to the same section with the RewriteEngine directive, so for example, your webroot .htaccess file would look like:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /path/to/app
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
The details of those changes will depend on your setup, and can include additional things that are not related to CakePHP. Please refer to Apache’s online documentation for more information.
(Optional) To improve production setup, you should prevent invalid assets from being parsed by CakePHP. Modify your webroot .htaccess to something like:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /path/to/app/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !^/(webroot/)?(img|css|js)/(.*)$
RewriteRule ^ index.php [L]
</IfModule>
The above will prevent incorrect assets from being sent to index.php and instead display your web server’s 404 page.
Additionally you can create a matching HTML 404 page, or use the default
built-in CakePHP 404 by adding an ErrorDocument
directive:
ErrorDocument 404 /404-not-found
nginx does not make use of .htaccess files like Apache, so it is necessary to
create those rewritten URLs in the site-available configuration. This is usually
found in /etc/nginx/sites-available/your_virtual_host_conf_file
. Depending
on your setup, you will have to modify this, but at the very least, you will
need PHP running as a FastCGI instance.
The following configuration redirects the request to webroot/index.php
:
location / {
try_files $uri $uri/ /index.php?$args;
}
A sample of the server directive is as follows:
server {
listen 80;
listen [::]:80;
server_name www.example.com;
return 301 http://example.com$request_uri;
}
server {
listen 80;
listen [::]:80;
server_name example.com;
root /var/www/example.com/public/webroot;
index index.php;
access_log /var/www/example.com/log/access.log;
error_log /var/www/example.com/log/error.log;
location / {
try_files $uri $uri/ /index.php?$args;
}
location ~ \.php$ {
try_files $uri =404;
include fastcgi_params;
fastcgi_pass <IP_ADDRESS>:9000;
fastcgi_index index.php;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
Note
Recent configurations of PHP-FPM are set to listen to the unix php-fpm
socket instead of TCP port 9000 on address <IP_ADDRESS>. If you get 502 bad
gateway errors from the above configuration, try update fastcgi_pass
to
use the unix socket path (eg: fastcgi_pass
unix:/var/run/php/php7.1-fpm.sock;) instead of the TCP port.
IIS7 does not natively support .htaccess files. While there are add-ons that can add this support, you can also import htaccess rules into IIS to use CakePHP’s native rewrites. To do this, follow these steps:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="Exclude direct access to webroot/*"
stopProcessing="true">
<match url="^webroot/(.*)$" ignoreCase="false" />
<action type="None" />
</rule>
<rule name="Rewrite routed access to assets(img, css, files, js, favicon)"
stopProcessing="true">
<match url="^(img|css|files|js|favicon.ico)(.*)$" />
<action type="Rewrite" url="webroot/{R:1}{R:2}"
appendQueryString="false" />
</rule>
<rule name="Rewrite requested file/folder to index.php"
stopProcessing="true">
<match url="^(.*)$" ignoreCase="false" />
<action type="Rewrite" url="index.php"
appendQueryString="true" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
Once the web.config file is created with the correct IIS-friendly rewrite rules, CakePHP’s links, CSS, JavaScript, and rerouting should work correctly.
If you don’t want or can’t get mod_rewrite (or some other compatible module) running on your server, you will need to use CakePHP’s built in pretty URLs. In config/app.php, uncomment the line that looks like:
'App' => [
// ...
// 'baseUrl' => env('SCRIPT_NAME'),
]
Also remove these .htaccess files:
/.htaccess
webroot/.htaccess
This will make your URLs look like www.example.com/index.php/controllername/actionname/param rather than www.example.com/controllername/actionname/param.


Girl, 13, in critical condition after gang with machetes attacked her
A gang of men forced their way into a house and attacked the woman and girl inside with machetes yesterday.
The teenage girl, 13, suffered serious stab wounds and is in a critical but stable condition in hospital.
A woman, 41, was also treated for stab wounds but has since been discharged from hospital.
The men attacked them with a baby present at the scene, which was not harmed.
The PSNI said the gang broke into the property on Trasna Way in Lisnaskea, Co Fermanagh, at around 9.15pm.
PSNI Detective Sergeant Keith Monaghan said: ‘This must have been a terrifying ordeal for those involved and we are determined to find the men responsible.
‘We have several lines of enquiry which we are progressing at this time but I would ask anyone with information or who noticed any suspicious activity in the area to contact detectives in Enniskillen and pass that information on.’

Alliance Fermanagh representative Matthew Beaumont said whoever carried out an attack in Lisnaskea needs to be caught quickly.
He said: ‘This attack in Lisnaskea, carried out by men carrying machetes, is to be condemned in the strongest possible terms.
‘Whoever was responsible for this horrific attack must be caught quickly and face justice.’
‘I hope the two females injured make a full and speedy recovery. This must have been a terrifying experience for them.’
