So am I the only one out there that likes to set aside blocks? 5 in a row here for ldap replicas, 10 over here for build servers, 101-254 on the next 5 subnets for dhcp addresses… and on and on. In a large organization you wouldn’t have servers mixed in with dhcp addressed workstations would you? So why not try to keep it organized on a small network?!

dd and netcat on one end, netcat and dd on the other. so simple, it’s like magic.

The amount of overlap depends on the engine, but most modern fuel injected high performance internal combusion engines have some valve overlap. While the intake valve is starting to open, the exhaust valve is starting to close. During this time there can be a back flow of air/exhaust in the direction of the fuel injector and intake manifold. This effect is stronger under high vacuum conditions (low absolute pressure). It is important to wait for this back flow to reverse before firing the injector. Once the exhaust valve is open, the velocity and flow of air will have increased as the exhaust gases have completely turned around and begun to escape through the exhaust port and out of the exhaust manifold. The optimal time to fire the injector is during this period, but as engine speed increases the injection must begin earlier to fully complete to avoid flowing fuel straight through the combustion chamber and right out of the exhaust port.

I needed a batch converter to turn non-xml style Excel spreadsheets (all the older versions) into delimited text files. If you run it without supplying a sheet name, it will list all the sheets available. You can also optionally define a delimiter to use instead of the default comma. So here’s my code along with part of the xlrd module which I tweaked a little.

If you have proxy settings set up in Internet Explorer already, then you can just run proxycfg -u and you’re done. It will add the registry keys for you. In the run dialog (Start -> Run) enter this command. It will flash the command prompt black screen and exit before you can see what it did, and that is fine because it requires no additional input. Or you can bring up a command prompt and run it so you can see the output if you’re curious.

proxycfg -u

If you don’t have them set up in Internet Explorer, you can specify which proxy server and port to use with proxycfg:

proxycfg -p rootninja.proxy.org:8002

This will create a new key in the registry named “Connections” under this key:

HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Internet Settings/

It will have a default string value (REG_SZ) and a binary value (REG_BINARY) named “WinHttpSettings” that contain your new system wide proxy settings.

If you’re behind a proxy and you run that, you’ll get something like “the other end hung up” or “Cannot get remote repository information” because git is trying to connect using port 9418 by default. I found a few sites saying all you need to do is change git to http in the url and it will work, but that did not work for me. But it’s an easy fix. Change git’s http.proxy and you’re done. Here’s how: (replace my proxy host and port 8002 with your own)
