Just discovered that Windows since XP comes with a command-line tool called “cipher”, which can be used to securely delete files. Shit. Why am i not told about this? I spent several hours when i need to do that in 2010. Updated: How to Secure Delete Files, Shred Files, Wipe Drive.

Question: What tools i can use to monitor network traffic? either build-in or 3rd-party. I like to have a graph view (For example, as in Task Manager) but also nice are tool that lets me know detail, such as what IP/port that's incoming/outgoing. Command line is fine. Or even some tutorial. Thanks.

Answer: start “Task Manager” (taskmgr.exe), then “Performance” tab, then “Resource Monitor …” (perfmon.exe). Or, just start “perfmon.exe”, then click on the “Open Resource Monitor”.

You can also use command line “netstat”. Or, if you want to sniff packets, install Wireshark.

Google Chrome Installed Location: New Era of Software Install Structure?

It's odd that Chrome is no longer installed under “Program Files” on Windows.

Perhaps, due to Google Chrome's philosophy of frequent update, putting it under AppData gets around many admin privilege problems. If so, this may signify some movement about software install location structure.

Notice that the new location is in a personal directory. That means, each user each will have their own copy of Chrome. Thinking in a traditional way, this means less disk use efficiency. But note that Chrome also integrates its own Adobe Flash. If you think about it, disk space is today never used up, at least not for the storage of software. (it is used up by video files, which are few hundred times more each.) So, multiple copies of a software ok. Also, putting the software for each user avoids many complexities developed by OS over the past decades for managing that. (For example, Windows Registry, and Mac uses Application bundle, and unix's ancient ways of {“/usr/bin”, “/usr/sbin”, “/usr/share”, “/lib”, “/usr/local/bin”, “/etc/man”, “/etc/share”, “~/bin”}.)
