由 余生长醉 提交于 2019-12-07 06:04:13
问题 I'd like to set a couple of environment variables on an Ubuntu machine (10.04), but I want to create their value via a script, much like: export THE_ENV_VAR=$(script_to_execute_and_use_stdout_from) I've tried setting in /etc/environment , but that only copies rhs verbatim I've tried executing a script in /etc/init.d/ at startup, but that does not seem to work. Ideas? 回答1: You need to write your export statement into /etc/bash.bashrc file, which is a system wide .bashrc file that will set

Why is my .Net app contacting Verisign?

由 柔情痞子 提交于 2019-12-07 01:27:31
问题 I wrote a .Net application that has nothing to do with network communication. There is not a single line of code in the whole application that uses the NIC, but my firewall has caught it trying to contact Verisign for some reason when the app starts. This does not happen regularly; as a matter of fact, it has only happened twice. The last time it happened, I was able to launch Wireshark before telling my firewall to allow access to the network. There was no real data transfer that I can tell.

问题 My application is pretty large, containing for instance 310 jars in web-inf/lib for a total of 100Mb. Starting the server, this step below takes 13s: Sep 16, 2014 1:05:33 PM org.apache.catalina.startup.HostConfig deployDirectory INFO: Deploying web application directory C:\apache-tomcat-7.0.47\webapps\ROOT The application relies on web-fragment and annotations to start properly.

When to use TryAddSingleton or AddSingleton?

由 余生颓废 提交于 2019-12-06 20:05:48
问题 I've noticed in some .net core examples there are calls to TryAddSingleton , and in some AddSingleton when registering services. Decompiler shows that TryAdd( called by TryAddSingleton) adds the specified param "descriptor" to the "collection" if the service type hasn't been already registered. Does it mean that it always safer to use TryAddSingleton, in case if some other method/library already registered the same class? 回答1: As you already noticed, the difference between TryAddSingleton and

Run Jar file on startup?

由 送分小仙女□ 提交于 2019-12-06 14:17:28
问题 I have a Java application that lives in the system tray that I compile to a executable jar file. I would like to add the option within my program to add to the system startup items. As I do not know of any uniform way to do this for all operating systems I assumed I would have to write code to do it for each one I intend to support so I started with Windows. When I attempted to add it to the registry at [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] using the code

application won't start on startup after adding a notifyicon

由 帅比萌擦擦* 提交于 2019-12-06 13:53:16
my app was working ok and it would execute on startup before. I added a notify icon and in my code,there are some places that this icon changes.I added all required icons in the root folder of my app,and everything is working fine with the icons,except the startup boot of my app. I can see my app's address in the "run" part of the registry(I mean everything is the same as when my app booted at startup properly).but my app won't run at startup anymore. any advice on my matter? PS:I thought I should explain my work a little bit and I wrote a little piece of app that has the exact same problem

问题 How to run shell script when XServer is started and lightdm also. I tried with init.d and rc.local in /etc directory, but my script is calling an gui application so that the reason I need to run it after XServer is started. I am using Debian Jessie. 回答1: According to this link .xinitrc in your home directory will be read and executed, otherwise the default /etc/X11/xinit/xinitrc is used. So you should be able to create this file and have the shell script started. 来源： https://stackoverflow.com
