• What is the best Handbrake preset for playing video files on Tivo Series 3

  - by deadprogrammer

  I have Mac2Tivo app running, and I can put video files on Tivo. Tivo supposedly supports avi and various other encoding, but half the time video's don't play. I'm pretty sure this has something to do with encoding options. So the question is, what is a good Handbrake preset to use for viewing stuff on Tivo?

• High quality / high speed dvd reader for Mac Pro

  - by deadprogrammer

  I have a high end Mac pro, but one thing in is that I'm unhappy with is a DVD drive. It's a Hitachi GH41N. Apple calls it a "superdrive", but it's anything but. The damn thing makes an amazing amount of noise, and isn't too fast either. What I want is a state of the art, fast, quiet DVD reader, preferably not even a burner. What should I get?

• Command line safety tricks

  - by deadprogrammer

  Command line and scripting is dangerous. Make a little typo with rm -rf and you are in a world of hurt. Confuse prod with stage in the name of the database while running an import script and you are boned (if they are on the same server, which is not good, but happens). Same for noticing too late that the server name where you sshed is not what you thought it was after funning some commands. You have to respect the Hole Hawg. I have a few little rituals before running risky commands - like doing a triple take check of the server I'm on. Here's an interesting article on rm safety. What little rituals, tools and tricks keeps you safe on the command line? And I mean objective things, like "first run ls foo*, look at the output of that and then substitute ls with rm -rf to avoid running rm -rf foo * or something like that", not "make sure you know what the command will do".

• How to recursively move all files (including hidden) in a subfolder into a parent folder in *nix?

  - by deadprogrammer

  This is a bit of an embracing question, but I have to admit that this late in my career I still have questions about the mv command. I frequently have this problem: I need to move all files recursively up one level. Let's say I have folder foo, and a folder bar inside it. Bar has a mess of files and folders, including dot files and folders. How do I move everything in bar to the foo level? If foo is empty, I simply move bar one level above, delete foo and rename bar into foo. Part of the problem is that I can't figure out what mv's wildcard for "everything including dots" is. A part of this question is this - is there an in-depth discussion of the wildcards that cp and mv commands use somewhere (googling this only brings very basic tutorials).

• The Coolest Server Names

  - by deadprogrammer

  These days server naming is a bit of a lost art. Most large organizations don't allow for fanciful names and name their servers with jumbles of digits and letters. In the olden days just about every system administrator came up with a unique naming scheme, well, sometimes unique - many just settled for Star Trek characters. To this day my favorite server name is Qantas - a Unix server that Joel Spolsky has or used to have. Why Qantas? You'd have to ask Rainman. So my question is this - what is the coolest server name or naming convention that you encountered? Let the geekfest begin. This question is marked "community wiki", so I am not getting any "rep" from it.

  Is it possible to share the same bash history file instance amongst all the terminal windows in real time? I want commands executed in one window to be available to all other terminal windows without having to restart them.

• Programmatically talking to a Serial Port in OS X or Linux

  - by deadprogrammer

  I have a Prolite LED sign that I like to set up to show scrolling search queries from a apache logs and other fun statistics. The problem is, my G5 does not have a serial port, so I have to use a usb to serial dongle. It shows up as /dev/cu.usbserial and /dev/tty.usbserial . When i do this everything seems to be hunky-dory: stty -f /dev/cu.usbserial speed 9600 baud; lflags: -icanon -isig -iexten -echo iflags: -icrnl -ixon -ixany -imaxbel -brkint oflags: -opost -onlcr -oxtabs cflags: cs8 -parenb Everything also works when I use the serial port tool to talk to it. If I run this piece of code while the above mentioned serial port tool, everthing also works. But as soon as I disconnect the tool the connection gets lost. #!/usr/bin/python import serial ser = serial.Serial('/dev/cu.usbserial', 9600, timeout=10) ser.write("<ID01><PA> \r\n") read_chars = ser.read(20) print read_chars ser.close() So the question is, what magicks do I need to perform to start talking to the serial port without the serial port tool? Is that a permissions problem? Also, what's the difference between /dev/cu.usbserial and /dev/tty.usbserial?

• Untar, ungz, gz, tar - how do you remember all the useful options?

  - by deadprogrammer

  I am pretty sure I am not the only one with the following problem: every time I need to uncompress a file in *nix I can't remember all the switches, and end up googling it, which is surprizing considering how often I need to do this. Do you have a good compression cheat sheet? Or how about a mnemonic for all those nasty switches in tar? I am making this article a wiki so that we can create a nice cheat sheet here. Oh, and about man pages: is there's one thing they are not helpful for, it's for figuring out how to uncompress a file.

  Do you know any good tools for nicely formatting messy php code? Preferably a script for Aptana/Eclipse, but a standalone tool will do too.

• How do I create a DSN for ODBC in Linux?

  - by deadprogrammer

  I am digging around in a Linux application that supposedly uses DSNs to connet to SQL Server. The connection stopped working and I can't find the credentials that are being used (all I know is the DSN's name). I am familiar with DSNs in Windows, but how are they created and where are they stored in Linux?

  I used to use Snippets Text Database, but now I switched to Evernote. At some point I need to migrate all of my old stuff there too. What about you?

• How do I quickly rename a mysql database (change schema name)?

  - by deadprogrammer

  Usually I just dump the database and reimport it with a new name. This is not an option for very big databases. Apparently RENAME {DATABASE | SCHEMA} db_name TO new_db_name; does bad things, exist only in a handful of versions, and is a bad idea overall. Oh, one more thing - this needs to work with InnoDB, which stores things very differently than MyISAM.
