kandi X-RAY | smeagol Summary
smeagol is a Rust library built to efficiently simulate large patterns in the cellular automaton Conway's Game of Life. It uses the HashLife algorithm developed by Bill Gosper to achieve tremendous speedups for repetitive patterns. A good explanation of HashLife can be found here. It also uses SIMD instructions to speed up the base case of evolving a 16 by 16 square grid of cells into the future.

QUESTION
I run a series of separate webapps which need separate configuration but all essentially use the same code, and consequently identical war files. The war file is able to read the path to its configuration file from an environment variable, and I can see how to set an environment variable for an entire Tomcat Context in the context.xml file.
However, I can't see how to run individual webapps in separate contexts; and all the webapps in the same context will see the same value of the environment variable and consequently load config from the same place.
Is there a mechanism to set different environment values for different webapps within a context; If not, is there some other mechanism (outside the WAR file itself) to specify different property values for different webapps, or a way to create a separate context for each webapps?
Finally, if I can move the configuration outside the webapp, is it possible to have several webapps use the same actual WAR file (as they are all identical apart from config,and it would make upgrades much easier if I just had to drop in a single WAR file)?

Answered 2021-Mar-15 at 06:06Edit: Looking at your code (particularly configuration.clj) it appears that you are using system environment variables (which are shared among all web applications). You should use environment entries instead and retrieve them through a call to InitialContext.lookup("java:comp/env/FOO")
instead of System.getenv("FOO")
.
Technically every application has its own , which is composed by (cf. Tomcat documentation):
- the values from
$CATALINA_BASE/conf/context.xml
, - the values from
$CATALINA_BASE/conf///context.xml.default
- the values from
$CATALINA_BASE/conf///.xml
or (if it is missing anddeployXML
of theis not false) the entries in
META-INF/context.xml
of your application.
Each more specific configuration file can overwrite the attributes of the more general configuration files, while the nested components are added up. Therefore you should probably define:
- the environment entries specific to each application in
$CATALINA_BASE/conf///.xml
, - the environment entries common to all applications in
$CATALINA_BASE/conf/context.xml
.
Remark: Usually is
Catalina
, while is
localhost
.
If you are using the same WAR file you can just place it outside of the document base (let's say /usr/share/my.war
) and create a bunch of .xml
files in $CATALINA_BASE/conf//

I have this problem as a part of my c-programming project. I read users input to char type array (char*str
) and I need to convert some parts of the string input to integer. The input might be "A smeagol 21 fire 22"
Here is some testing. I try to get x=40. This code's gives x=-4324242. Why this code don't work?
...ANSWER
Answered 2020-Apr-07 at 16:48Type casting a char
pointer or array to int
or another numeric type will not give you the numeric value of the text in the string.
You should use the functions strtol

QUESTION
My JavaScript is not correctly changing the actor-images display from "none" to "block" and I am unsure on what the problem is as this should be working correctly. I have tested this code within the web browser and the console reads back no errors, yet when in use, the images are not displaying and I can't figure out what the problem is.
...ANSWER
Answered 2018-Apr-23 at 18:40After minutes of debugging
You container and the container that holder that divs for the images have the same className so when this code
actorImages[slideNumber - 1].style.display = "block";
is performed the main container shows up and when you click next it the codes hides the main container that holds the images and the set the first img to block but since the container is hidden we can't see the img so i would suggest the following :
Add another class for your main container like this
