I've been floating around the Google and everything's getting more confusing now. What i want to know is how to install Memcache or Memcached. Even which one to install, i'm still not sure. It is super confusing.
I'm on Redhat RHEL. Actually i have installed Memcached (with 'd`) on my Web Server. Then according to the articles, i enabled Php Extension, etc. Then what is supposed to happen? Totally no improvement in performance.
Then i feel thats not enough and i googled again. Some say to install on MySQL Server. So what about PHP Extension and Drupal Module which are supposed to be configured, if i install it on MySQL Server? I'm really not getting it.
So i have Drupal 7 and please let me know in simple way for which is the right one to follow :(
Memcache or Memcached ? (Why this two so confusing?)
Where to put at?
Does it really need Drupal Module to work?
Please simply give me a straight dummy guide :(
"Memcache vs Memcached" - first one is a module (extension), second one is the daemon. See "Memcache Vs. Memcached" for full explanation
"Where to put at?" - you said you had it already installed on your server, it should be installed easily with some package manager e.g.:
pecl install memcache
"Does it really need Drupal Module to work?" - Yes, Drupal needs to know that you want to use memcache. The Drupal module will move cache, sessions and lock tables into memory (see https://drupal.org/project/memcache).
To make memcache module work, you need to put the following into settings.php (change you module path respectively):
# Memcache
$conf['cache_backends'][] = 'sites/all/modules/contrib/memcache/memcache.inc';
$conf['cache_default_class'] = 'MemCacheDrupal';
To see whether it works, go to "admin/config/system/memcache" (this is Drupal 7 path) and turn on "Show memcache statistics at the bottom of each page" - if everything works well, you should see something similar at the bottom of the page:
OPERATION BIN KEY HIT
get cache_bootstrap cache_bootstrap-variables 1

My problem is that I can't use R-studio at my work place as the IT does not support it . I want to use R and R-studio that installed on my personnel laptop on my company laptop ( using a modern browser which is behind firewall ) . Some of the options I am thinking of two two things
should I need to build a docker for R and R-studio (I see base images are already available) , I am mostly interested in basic R , Dplyr (haven ,xporter, and Reticulate ) packages .
Should I have to use a binder . I am not technical person and my programming skills are very limited can any one suggest me way .
What exactly are the difference between using Docker option vs Binder ?
I know I can use R-Studio online and get my work done but with the new paid account I am running out of project hours and very slow sometimes . Thanks in advance
Here are some examples beyond the modern RStudio MyBinder example:
https://github.com/fomightez/pythonista_skewedf
https://github.com/fomightez/r_phylogenetics_worshop
https://github.com/fomightez/chapter7/tree/master/binder
The modern RStudio MyBinder example has been set as a template on GitHub so you can use
The first one is for a special use of a package not on conda. And I started that one from square one.
The other two were converted from content by others to aid in making them Binder-ready.
You essentially list everything you need from conda in the environment.yml along with the appropriate channels. If you need special stuff not on conda, you need the other configuration files included there.
Getting everything working can take some iterations on adding things, letting the image get built, and testing your libraries are available. Although you seem to think your situation is not overly complex.
The binder launch badges you see are just images where you modify the URL to point the MyBinder federation site at your repository. Look at the URL and you should see the pattern where you put studio at the end of the URL pointing at your repo. The form at MyBinder.org site can help with this; however, most often it is easier to just adapt a working launch badge's code copied from elsewhere. The form isn't set up at this time for making the URLs for launching to RStudio.
Download anything useful your create in a running session. The sessions timeout after 10 minutes, although RStudio usually keeps them active.
Lack of Persistence and limited memory, storage, & power can be drawbacks. The inherent reproducibility and portability are advantages.
MyBinder.org doesn't work with private repos. If you have code you don't want to share, you can upload it to the temporary session, using the repo for specifying the environment. You could host a private binderhub that does allow the use of private git repositories; however, that is probably overkill for your use case and exceed your ability level at this time.
GitHub isn't the only place to host repositories that can be pointed at the MyBinder system. If you go to the MyBinder.org page and click where it says 'GitHub' on the left side of the top line of the form, you can see a list of the sources at which you can host a repository and point the system to build an image and launch a container with that specified image.
Building the image from a source repository takes some minutes the first time. Once the image is built though on the service, launch is typically less than 30 seconds. Each time you make a change on the source repo, a build is necessary. Some changes don't cause the new build to be as long as the initial one as some optimizing is done to only build what is necessary after a change. Keep in mind there are several members of the federation around the workd and if traffic on the internet gets sent to where the built image isn't yet available, it will be built from scratch again first.
The Holepunch project is out there to offer some help for users working in the R ecosystem; however, with the R-Conda system that is now integrated into MyBinder it is pretty much as easy to do it the way I described. Last I knew, the Holepunch route makes a Dockerfile that isn't as easy to troubleshoot as using the current the R-Conda system route. Dockerfiles are essentially a last ditch configuration file that MyBinder can handle. The reason being the other configuration files are much easier and don't require knowing Dockerfile syntax. MyBinder aims to offer the ability to take advantage of Docker offering containers with a specified environment without users needing to know anything about Docker.
There is a Binder Help category for posting to get help at the Jupyter Discourse Forum. Some other examples of posts already there may help you troubleshoot.
Notice of a common pitfall
Most of the the configuration files for making a repository Binder-ready are simply text and can be edited right in the GitHub browser interface, without need to git or even cloning the repo locally.
Last I knew, there are two exceptions to this. The postBuild and start configuration files have settings that allow them to be run as scripts and these get altered in a way they no longer work if you edit them via the GitHub browser interface. (This was my experience when last I tried. Your mileage may vary or things may have changed now.) To edit those, you have to have git available on a system you have and pull one from some other source. Then edit that on your machine that has git working & add it your repo and push it back up from your local computer.
(If this is a problem, you can post in the Jupyter Discourse Forum Binder help category and you and I could coordinate where I fork and edit those files in your repo to your specifications and then make a pull request to update your source of the fork with those changes.)
If you are using Jupyter notebooks extensively then it may make sense to use Binder
But if you simply want to use R and Rstudio, then all you need is docker. A good resource is

Bit of a weird one. For some reason one of my DNN modules keeps being converted into an Application in IIS7 in my development environment. Meaning when I try to view a page that contains that module it can't find the module correctly. It's ok if I go into IIS and delete the application, then restart the site but is a bit of a pain and am little worried it might do this when uploaded to the live server and disable the whole site.
Anyone encountered anything like this before? Any thoughts?
This is a common problem with my VS templates, though not for everyone, and it doesn't happen all the time. It stems from Visual Studio, so it shouldn't ever be a problem on your production servers, unless you upload source and try to compile there, than it might be an issue.
HuwD,
A good resource might be my module template installation video which gives good information on setting up your development environment and debugging issues (regardless of the template you use). Check out between 1:30 and 5:00 minutes for the environment setup, and after 19 minutes some of the troubleshooting.
A couple common problems I see Visual Studio doing is creating an unwanted virtual directory on the DesktopModules folder and/or creating an unwanted web.config in the module's root.
Another good resource is Dnnhero.com. In the development section there is a series on DNN7 environment and template setup.
You may want to give a try a free module called Users Importer - A bit old but worth a try.
Here is a paid alternative: Bulk User Manager
I have created a local version of my Drupal website to do dev work on. But when I add new modules to the local version they do install but they do not enable correctly. For example I added the legal module, enabled it, but when I go to site configuration to edit it, the legal section does not appear. Any help please?
The problem is that not enough memory will be allocated to the service to allow for new modules which require more memory to be ran, try putting
ini_set('memory_limit', '256M');
in the sites/default/settings.php file.
This is a really old thread but thought it was worth adding the following.
I had this problem recently on a local dev install (using Acquia Dev Desktop, by the way). Turning off the Memcache module resolved my issue.
So I've recently setup a LEMP server and have managed to work may way through some of the configurations. I'm now to the point where I can begin writing php scripts and building basic pages. Looking at the php5-fpm wiki there aren't any pages discussing any changes I should expect as far as php scripts and such are concerned, only installation/configuration settings.
Is everything beyond the installation/configurations steps business as usual? From the point of view of a php developer what changes should I expect/make? How can best take advantage of the fpm version (in the php code, not module/system configurations)? I'm focused on comparing well-written php in both cases.
When I made the switch myself, I got to know a few perks about this kind of setup, such as APC file upload progress does not work out of the box (and you're better off using something else, such as nginx-progress-upload and/or JS File API); Some header names might have changed (prepending HTTP_); and a new and very useful function called fastcgi_finish_request.
For more information, though, look around the PHP-FPM Manual.
Only major gotcha I can think of is that some functions in the pcntl extensions, such as pcntl_fork, are not supported when running under FPM. (However, they're not supported under mod_php either, so this shouldn't come as too much of a surprise.)
I have a Windows 2003 Server with IIS, I installed VisualSVN Server on it.
I have two developers, who are going to use TortoiseSVN.
Since this is my first time ever setting up a SVN server I am kind of confused on how this will all work. The way I see it, each developer would have a copy of the repository on his or her local pc, would each person be required to have IIS installed on their PC as well to test their copies before checking out?
Should I create a testing folder on the server and then a production ready? It seems as if that would cause more issues with copies?
What would you do?
EDIT
I dont know what I was thinking, I forgot that VS has a built in IIS when you debug so the issue about setting up IIS on either client or server is now a non-issue. But I am confused, I imported the site into the repo, it said it was on revision 2 but I dont see any of the files in the repo folder. Do I create a virtual folder in IIS pointing to the repo that I created?
No, each developer uses your repository, and checks out their own copies to do their work. They do not need IIS or svn, etc, installed on their systems.
I recommend reading up on the Subversion FAQ.
Your devs don't have a local repository, they have a Working Copy on their PC. Typically, this is the most recent version of the app with whatever changes have been made by the developers but not committed yet.
As this is a web app, then your developers will need some kind of web server locally to test it - this could be IIS, or Visual Studio's built in web server (although that does behave differently to IIS in subtle ways).
You said in a comment: "My problem is I dont want the devs to commit to the live site in case there was a bug.".
The devs commit to the SVN repository on the server: at some point you will want to export (aka 'publish') a copy from the latest version in your repository to your live site. In order to make sure this works, you can check out a specific version from the server, test it, and if it passes the tests upload it: devs will always check in code with bugs (even though it builds) as it's better to check code in frequently than build up lots of changes locally then commit them, as there are bound to be conflicts with work other developers have done.
Branching and Tagging are useful concepts here: when you have a version which is almost right, you 'branch' it away from the main 'trunk' of the source code tree, fix any issues in the branch (back-porting to the main trunk as required), then when you have a working version you 'tag' it (as version x.y.z) and upload it. This way you can always refer to the particular version of the code you have uploaded, which makes it a lot easier to identify bugs which turn up in production. As others have suggested, read the SVN documentation for more info.
It depends on how you work. There are other discussions about folder structure and such which play directly into how you use version control.
Uh, no, no local repositories. Setting up SVN is easy, well almost. You'll want to look for the svn windows installer and set it up on the server. You'll want to install Apache and then you'll have a little hurdle setting up the http.conf file to expose svn over http. There's a little complexity with setting up security so go with Windows Authentication, you'll need WebDav, google it.
Once that's done, any svn client can hit it and checkout a copy and work with SVN normally. If you get really stuck, comment here and I'll go get a copy of our install and config for you.
The good news is that it's rock solid, once you get it setup it'll run forever.
"Pragmatic Version Control Using Subversion" and the SVN red-bean are the two sources you need to see.
Set up SVN on a single server and have all your developers point to it.
I've installed tortoise on the server and do Updates / Checkouts of the release website. Some people don't like checking in compiled code, but I like having the production compiled site in SVN.
If you use tortoise on the server, Do the initial checkout to the inetpub/website directory and then on rollouts you just need to update the directory using tortoise->update
Of course checkin to rollout is considered bad practice without first rolling out and testing on staging servers, but depends on your team size.
I have used the following resources for learning SVN:
http://www.polymorphicpodcast.com/shows/subversion/
http://www.dimecasts.net/Casts/ByTag/SVN
Found both quite good, and learning by watching can be easier especially for getting started.
No - your central server will maintain the repository. Your developers will get copies of the repository, make changes, and then commit them to your repository.
You actually have quite a few things to figure out if you want to do a successful deployment of subversion.
One really good article about setting up subversion on Windows - https://blog.codinghorror.com/setting-up-subversion-on-windows/
No, SVN server must be installed on a single computer. Each developer point at this computer and get locally (and eventually) a full copy or a partial copy of the repository.
You may also buy a book from O'Reilly about Subversion. Don't remember the title, sorry, but it helps me a lot.
All the best ! Sylvain.
