Configuration How to efficiently store and serve lots of small images on the web site?

On my web site I want to serve user a page with a lot of small pictures on it, kind of like thumbnails in Windows. All pictures are files ranging in size from 1KB to over 300KB, but usually no bigger than 5KB. Currently all those images are located in a folder on the web server (linux+apache), but I don't think this is the best solution, especially if I'll have to expand to more than one web server and when I'll have thousands of them. So, should I maybe place these files in the database (ca

Configuration Jetty - set system property

I run webapp on Jetty. The configuration for the app come from file that lives on the same server where Jetty is running. Inside the app I rely on the system property to obtain path to the file so I can parse it. E.g. final String loc = System.getProperty(FACTORY); Now I can start jetty with D switch to provide $FACTORY on the command line but I rather put it in jetty.xml if I can. I know there is <SystemProperty /> tag but that seems to just provide system value that already exists for

The solution (or workaround) was edit the eclipse.ini to add the -vm property and the path to the java version 1.6, that way they don't need to change the configuration of the system. The

However, the dedicated server that my data scientists used to submit spark jobs have its spark.local.dir filled up gradually.

Configuration Is there a way to order JUnit testcases in TeamCity?

Let's say I have three JUnit test cases, namely TC1, TC2 and TC3. Is there a way to configure TeamCity or pom somehow, so that when I remote run, the order will be TC1 -> TC2 -> TC3 always? Right now, because of unordering in test cases, all these tests start with the same functionality (for example: creating a user), which takes a pretty big amount of time. I would like to do that functionality in the first test case only (TC1 in this case). I am open for any other approaches also. Thanks

Configuration con:settings Elements in Workspace and Project Files

I am using the free edition of SoapUI (version 4.6.1) with multiple workspaces. One of my frustrations is that SoapUI does not seem to support workspace-level custom properties.

My intuition & hope is that these elements allow workspace- or project-level additions to or overrides of settings I see in my general soapui
