update running balance using hibernate in multiuser environment
Since the entities representing the table rows are independent of each other, hibernate can not know that the calculation of the balance is based on outdated data. Solution 1 (by far my preferred one): Calculate the balance in the db (using triggers) and mark the balance attribute as @Generated(value = GenerationTime.ALWAYS) so that the entity will be updated after a write. Hibernate and database will take care of the rest. If you have to do the balance calculation on the application level multiple solutions with some drawbacks come to mind: Solution 2: Don't use user transactions to commit multi-user dependent data. Create something (e.g. some queuing mechanism) to serialize the save requests. Do the processing in a user independent transaction. Drawback: The user won't see th

Amazon web service load balancer unable to balance the load equally
There could be a number of reasons for this. Its without doing more digging, its hard to know which one you are experiencing. Sticky sessions can result in instances traffic becoming unbalanced. Although this depends heavily on usage patterns and your application. Cached DNS resolution. Part of how the ELB works is to direct traffic round robin on a DNS level. If a large number of users are all using the same DNS system provided by an ISP, they might all get sent to the same zone. Couple this with sticky sessions and you will end up with a bunch of traffic that will never switch. Using Route 53 with ALIAS records may reduce this somewhat. If you can't get the ELB to balance your traffic better, you can set up something similar with vanish cache or other software load balancer. Not as c

Error in if statement for setting balance
console.log("Your balance is (balance - 5.00)."); should be console.log("Your balance is %s.", (balance - 5.00)); The former will just say "Your balance is (balance - 5.00)" because JavaScript does not treat words like "balance" as variable references when they appear inside a string literal. In the second, the message format string is distinct from the expression you want to display, and console.log replaces %s sequences with the other arguments.

How can you adjust white balance setting for a custom iOS Camera App?
I haven't been able to find any info on setting the camera's white balance (though I don't know for sure that it's not possible). But, you can always post-process with the white balance Core Image filter (aka CIWhitePointAdjust). You can read about applying Core Image filters here.

Load Balance: Node.js - Socket.io - Redis
Redis only syncs from the master to the slaves. It never syncs from the slaves to the master. So, if you're writing to all 3 of your machines, then the only messages that will wind up synced across all three servers will be the ones hitting the master. This is why it looks like you're missing messages. More info here. Read only slave Since Redis 2.6 slaves support a read-only mode that is enabled by default. This behavior is controlled by the slave-read-only option in the redis.conf file, and can be enabled and disabled at runtime using CONFIG SET. Read only slaves will reject all the write commands, so that it is not possible to write to a slave because of a mistake. This does not mean that the feature is conceived to expose a slave instance to the internet or

Azure Traffic Manager Load Balance Options
Traffic manager comes into picture only when your application is deployed across multiple cloud services within same data center or in different data centers. If your application is hosted in a single cloud service (with multiple instances of course) , then the instances are load balanced using Round Robin pattern. This is the default load balancing pattern and comes to you without any extra charge. You can read more about traffic manager here: https://azure.microsoft.com/en-us/documentation/articles/traffic-manager-overview/

Azure windows virtual machine load balance
You need both the virtual machines to be under the same cloud service. Only then you get the option to load balance them. There is no way add existing VMs to the same network. there are operations in the Service management API (usable through powershell) to create a new VM. You can use that to create a fresh VM from your existing image and connect it to the same service as your first VM. Then you'llhave the necessary options enabled for load balancing.

Why doesn't Nginx load balancing balance bandwidth?
It sounds like the configuration is doing exactly what you asked it to do. You configured a proxy on the first server IP, right? So data has to go from the user to the proxy, then to the server, then the reply from the server back to the proxy and then to the user. It's triple because the first server sees three flows (both servers' output from the proxy and the second server's input to the proxy) while the second server sees one (its output to the proxy). It is perfectly balancing the traffic into equal flows, the first server just sees three flows and the second just one. As for how you fix it, it depends what's wrong with it and what you're trying to accomplish, which you haven't told us.

Does SQL Server Service Broker load balance when External Activator is used?
To utilise the built-in load balancing you would need to deploy the service to more than one sql server instance. I suspect that isn't quite what you are planning, so you will have to come up with a custom method, such as having an internal activated procedure that forwards your arriving messages into one of your four queues that the external activation processes look at.

how to internally load balance multiple instances of web/worker roles in Azure?
There is no internal load balancer in Windows Azure. The only load balancer is the one that has the public IP Addresses. If you want to load balance only internal addresses (workers) you have to maintain it yourself. Meaning you have to install some kind of a load balancer on Azure VM, which is part of the same VNet. That load balancer may be of your choice (Windows or Linux). And you have to implement a watchdog service for when topology changes - i.e. workers are being recycled, hardware failure, scaling events. I would not recommend this approach unless this is absolutely necessary. Last option is to have a (cached) pool of IP Endpints of all the workers and randomly chose one when you need.

Setting up my Java Environment. Jar/CLASSPATH
1) How do I know what my CLASSPATH is? It is a system environment variable. On UNIX/Linux, you type "echo $CLASSPATH" to see what it is set to. 2) In the first statement, I have written the complete address of the folder it is in. Even then it wont find it? Does my project has to be pointed by CLASSPATH only? That is a package name. It tells Java where to look within the classpath. Normally, the package name doesn't match the absolute path of the file. For example, suppose I have a class located on my file system /user/local/com/stackoverflow/foo. Java needs the classpath set to /usr/local so it knows where to look for the class. Similarly, the file might be in the jar and the classpath says were to look in the jar. 3) Say my CLASSPATH points to Desktop [i.e. I set

Setting up virtual environment in PyCharm
In settings, under the Project section (in the left pane) go to Interpreters. From there you can select a found environment or click the + to add your own from a path. Find the environment you created and add it to the list. Then, once you select the environment you can see the installed modules underneath. You can add new modules through their built in pip. After that, it'll take you to the first page where you have to select your custom environment from a drop down. Good luck! Edit: Reread your question. Sometimes when I can't get the module to be recognized in PyCharm, I do a pip install through the command line in the virtual environment. Then restart PyCharm. Navigate to the environment in cmd and run python -m pip install -U SOUNDCLOUD_MODULE and it'll work.

Setting up a developing environment with appfog

But if you are going with SQLite, you should consider using a persistent database solution. It is not recommended on production environment in AppFog. Every time you update your app, your SQLite database will be blown away. Since AppFog databases are not externally accessible, you'll have to tunnel into them.

Setting environment specific htaccess rules
No there isn't any way to set those things via some url detection. You can't make normal if conditions surrounding some of the things you want (AddType SetHandlers and ErrorDocument). You could use env variables and mod rewrite but I don't think you'll like the end result. You'll have to do something like this using env|E=[!]VAR[:VAL] syntax If you were in the httpd.conf or vhost file you might be able to separate your different setups by using <directory> sections </directory>. But Directory is not allowed in htaccess. Also I wouldn't do this in a production environment anyways since something could go wrong and I would think the detection is slower and not needed. Perhaps you may want to look into a build script you run to create/deploy your different setups for developmen

Having trouble setting an environment variable for apache on Mac
I do hope no one has wasted time looking at this issue. I have been caught out by a predecessor who set up an alias for apachectl in /etc/bashrc! It turns out I was not executing /usr/sbin/apachectl but, instead, /opt/local/apache2/bin/apachectl This script imports /opt/local/apache2/bin/envvars and not /usr/sbin/envvars. Nor does it use launchctl... the explains why none of my steps to set the environment worked. Once discovered I got it working straightaway. Sorry to have troubled you all.

Setting up a WingIDE environment for python scripting for MCEdit
If you are running MCEdit from sources you can probably set up a Wing project with mcedit.py as the main debug file and just debug the whole thing, then you'll be able to set breakpoints, etc also in filters. Alternatively, you could copy wingdbstub.py from your Wing installation into the same directory as the filters and add 'import wingdbstub' to start debugging when the filter is run. You will need to click on the bug in lower left of Wing's main window to Enable Passive Listen (or "Accept Debug Connections" in Wing 5+). You may want to set kEmbedded=True in wingdbstub.py (if Wing drops the debug connection after the filter is used once, this indicates the filters are invoked in a way that requires this flag to be set). If you still run into problems w/ dropped debugger connections

Setting up a java/j2ee development environment with: Eclipse, Tomcat and Vagrant
What files/folders am I supposed to share? (not the whole eclipse workspace I suppose) IMHO, share the project you are working on is enough. This way you may have one VM for each project. You have two options to generate the war: build on host; build on VM (preferred). If you choose Option 1: Since your project folder is shared with VM, you can copy the war to $CATALINA_HOME/webapps once you ssh to VM. I would suggest Option 2 because you could keep the build environment as close to your production environment as possible. Am I better off using a exploded or a normal war archive? I would use normal war archive, but there's not much difference here. How do I configure Eclipse (which lives on the host) to see the remote Tomcat (the one that lives on the guest).

Setting development environment flag and eliminating debug code when deploying to production
This question is not specific to Sublime Text at all, or any text editor, but a generic question how to preprocess and debug (JavaScript) source code. First, the easiest approach would be have some kind of global debug flag in your codebase. window.DEBUG = true; function log(a, b, c, d) { if(DEBUG) { console.log(a, b, c, d); } } if(DEBUG) { // Do dev stuff } else { // Do produection stuff } log("foobar") // Does not need to be wrapper, as log() itself is functional only in debug mode You can set the debug flag depending on your URL: if(window.location.href.indexOf("localhost") >= 0) { window.DEBUG = true; } When you deploy your JavaScript to production, you usually run it through minimizing and bundling tool.
