Sending UDP from cmdline

Useful if you are testing something

echo "HELLO" | socat - UDP4-DATAGRAM:192.168.1.0:19838,sp=19835,broadcast,range=192.168.1.5/32

watch echo "HELLOA `date`" | socat - UDP4-DATAGRAM:192.168.1.0:19838,sp=19835,broadcast,range=192.168.1.5/32

Automating tasks over telnet.

Ok. So it is a Stone Age and no one knows what SSH is. Everybody is using telnet.

Let's automate a service restarting task.

Cool and easy as 1,2,3.

{ \

 sleep 2; \

 echo "root"; \

 sleep 2; \

 echo "password"; \

 sleep 2; \

 echo "ps ax | grep my_cool_service"; \

 sleep 2; \

 echo "OLD_SERVICE_PID=\`ps ax | grep my_cool_service | awk '{print \$1}'\` && kill \$OLD_SERVICE_PID"; \

 sleep 2; \

 echo "service my_cool_service start && ps ax |grep my_cool_service"; \

 sleep 4; \

 } | telnet 10.10.10.10

  

Gradle over proxy

Ok. Everyone knows that. This time it's a note for me-self.

vi ~/.gradle/gradle.properties

systemProp.http.proxyHost=www.proxyhost.org  systemProp.http.proxyPort=8080  systemProp.http.proxyUser=userid  systemProp.http.proxyPassword=password  systemProp.http.nonProxyHosts=*.nonproxyrepos.com|localhost

Have fun.

Building iOS apps for Simulator with Xcode 5 with command line

Things a little changed since Xcode 4

If you want to build your project for simulator 

and want to do it with the latest and the greatest version of Xcode - version 5.x

and want to do it with command line utility xcodebuild, 

because you need this for Continuous Integration or someth, 

then: 

1. In your Build Scheme for Simulator in project's "Build Settings" in section "Code Signing" set:

• "Don't Code Sign" for "Code Signing Identity"
• "None" for "Provisioning Profile"

2. In command line use iphonesimulator7.0 as desired SDK

(even if you have downloaded SDK 6.1, it won't help. not without other voodoo dark magic)

/usr/bin/xcodebuild -verbose \

  -project MyCoolProject/MyCoolProject.xcodeproj \

  -scheme MyCoolProjectSimulator \

  -configuration Debug \

  -arch i386 \

  -sdk iphonesimulator7.0 \

  TARGETED_DEVICE_FAMILY=2 \

  clean build

where TARGETED_DEVICE_FAMILY is iPhone (1) or iPad (2)
