I call this Argument Error #1. For those who don’t know, I love computer error messages in the same way a Swedish banker might demonstrate love and fervor for a terrorist captor. I’ve passed strings and integers to functions before but I’m not sure how I might pass this painting. Thus, g++ would probably give me an argument error for this.

Sorry for the bad photograph. I’ll make a better one once I get off spring break. I’ll also get back to ALL the emails. Every last one of them. And phone calls. And text messages. I disconnected myself while I worked on this.

is the best man in the middle attack thingy for http requests I’ve ever seen. If you ever want to quickly reverse engineer some program that connects to the internet or a private iphone api (like mint.com’s) You can configure your os to use iptables to http packets through this program. Or, if a program can detect that your using a proxy server, you can configure squid to act as a hidden proxy but then use proxy strike as its proxy. Kind of like a proxy-proxy. Next time I bother reverse engineering something I’ll post the code to this.

Fortunately, there’s a program called sshfs which mounts an sftp connection as a drive using fuse. To install in Ubuntu,
sudo apt-get install sshfs.

Then, when you want to connect to an sftp server, add two aliases to your bashrc file like this:

#mounting alias
alias seanneilan.com='mkdir ~/ftp/seanneilan.com/; sshfs -o uid=1000 -o gid=1000 sneilan@seanneilan.com:/ -p 22 ~/ftp/seanneilan.com/; cd ~/ftp/seanneilan.com/home/sneilan'
#unmounting alias
alias useanneilan.com='cd ~; fusermount -u ~/ftp/seanneilan.com; rmdir ~/ftp/seanneilan.com'

To install

Choose a name for your connection. Mine is seanneilan.com. Copy/paste & replace all instances of seanneilan.com with the name of your connection. Replace sneilan@seanneilan.com:/ with your username, host & initial directory. Be sure to create a folder called ftp in your home directory.

How it works

1. Make a folder for the files inside a folder called ftp in your home directory.
2. Use sshfs to mount a connection inside that folder under your userid (no root required!) The uid=1000 & gid=1000 is your user id & group id on every linux system.
3. Then, changes to that directory!
4. The unmounting alias goes to your home directory, unmounts the ftp connection and removes the directory.

Issues

If you lose your connection, you’ll have to unmount, remount and reopen all your files since the file pointers will get messed up.

Ideas

I was thinking about implementing something with fschange. That way, I could make a program that makes a copy of whatever you’re about to edit and instead opens up the copy rather than the one on the sftp server. Then, when you save, fschange will notify some program to copy/paste your changes over to the sftp server. Should the sftp connection drop, the program will automatically reconnect. I might do this later.

Tips

It also helps if you use ssh keys.

You can have different programs running on different workspaces and switch them by pressing Alt-~-0-9. Bring up a new program with Alt-p-p & then type the name of the program. Kill a program with Alt-Shift-C. Send windows to other desktops with Alt-Shift-W or E. Use Wmii bindings like mine. There’s a lot more to this xmonad and you can read my config file or just go here.

Xmonad is definitely an advancement in interaction with computers for those who are willing to go an extra step to learn new things.

I’ve been running Linux for a long time. For the most part, I’ve understood the various linux desktops as largely trying to be like windows but more powerful. (At least when you look at Gnome or KDE, the great front ends to Linux.)

I have added the arbitrator, controller, buildmanager and constructionmanager classes to the project. The constructionmanager class is halfway done & the other three classes haven’t been tested. I need to complete the holy trinity of construction, production and morph manager to test them properly. Testing of course will probably take longer than it took to write, but, hey, by January 1st, we should have this whole pybwsal thing done.

So far, the building placer has been implemented & I was working on implementing the building manager but unfortunately ran into issues yesterday. See http://code.google.com/p/pybw/issues/detail?id=20

In the meantime, I will work on programming the bid system as Chad Retz (and perhaps others) from the bwapi-jbridge project is interested in that.

And if you care, here is his old bio:

Old as dirt. retired. I am a Christian but I am also a mortal man. Not perfect, born in sin so I believe I must rely on something more powerful than man to guide and help me during my bad times. I want to do good when I am able and avoid doing bad . That is my goal although it is not possible to achieve all the time.
