My favorite out of this:
grep -P "[\x80-\xFF]" file.xml


This was really useful when compiling AWS Cloudformation templates since you can't have certain characters in the JSON.

Fedora - VNC through systemd/xinetd

Configuring Fedora 17 for Xvnc through systemd/xinetd I found a number of links around but nothing exactly covered my setup.  I wanted to be able to run an X11 session from home as securely and efficiently as possible.  After configuring my home server like this: sudo yum install xinetd tigervnc-server-minimal sudoedit /etc/gdm/custom.conf [security] RelaxPermissions=0 [xdmcp] Enable=1 HonorIndirect=1 [greeter] Quiver=1 sudo useradd -d /var/empty/vncuser -m -s /bin/false vncuser sudoedit /etc/services vnc-1280 5910/tcp # VNC Listener sudoedit /etc/xinetd.d/vnc # BEGIN service vnc-1280 { socket_type = stream protocol = tcp wait = no user = vncuser server = /usr/bin/Xvnc server_args = -inetd -query localhost -desktop 1024x768x24 -once -geometry 1024x768 -NeverShared securitytypes=none } # END sudo systemctl start xinetd.service And you will need to restart GDM.  I couldn't get the systemctl restart prefdm stuff quite right, so I reboote...

Working through the golang tour

Exercise: rot13Reader https://tour.golang.org/methods/23 This was was tougher than I thought,  Mainly because you really have to understand the implied pieces that are needed.  I ended up solving this with a map rather than the github answer key I found. package main import ( "io" "os" "strings" ) type rot13Reader struct { r io.Reader } func main() { s := strings.NewReader("Lbh penpxrq gur pbqr!") r := rot13Reader{s} io.Copy(os.Stdout, &r) } func (rot13 rot13Reader) Read(b []byte) (n int, err error) { n,err = rot13.r.Read(b) for i:=0;i<n;i++ { b[i] = m[b[i]] } return n,err } var m = map[byte]byte{ 'A': 'N', 'B': 'O', 'C': 'P', 'D': 'Q', 'E': 'R', 'F': 'S', 'G': 'T', 'H': 'U', 'I': 'V', 'J': 'W', 'K': 'X', 'L': ...
