I'm open to pitching in with the code.  The seams between chat and main are bothersome to me.
Being able to join chat rooms from the Android app would be a plus! It would truly make us connected on the go, instead of having to sit down at our desks and open a browser window. This will allow more users to fully utilize the chat system and join events no matter where they are.
Prevent Photos app on OSX from launching when plugging in device I am confused by the behaviour of Currency fields in Multi-Currency environments. My app does a calculation on day X and stores its result in a record.  The custom page which displays a SUM of those values should always display the same as a database query. But...it does not. If I change Exchanges Rates those values change.  Was it wrong to store currency values in a Currency field, am I querying incorrectly or do I need to display a values that is manually calculated?  How does Multi-Currency and Currency fields work together? When are currency values converted and which conversion rate is taken into account?  I am confused?! More than 9 hundred as hundreds?

Printing reverse of any String without using any predefined function? How can I completely remove ecryptfs from my system and delete .Private? Few days back I have installed ecryptfs, created a private directory using it. Now my Ubuntu login became super slow. I have tried removing ecryptfs from Synaptic. I found It, it can not be deleted that way. Somewhere I have read about this command  ecryptfs-setup-private --undo   But this command displays a rather confusing list of commands on terminal. I don't want to mess up my installation, neither want to loose my administrator account.  Now my question is, how can I safely remove /home/user/Private (.Private) and remove ecryptfs encryption ? Compact way to assign values by slicing list in Python Correct spelling of "program" When are stopovers permitted on Japan Railways (JR) trains? Hanging indent inside list I would like items in a list to have a hanging indent (that is, for all lines after the first to be indented by a space or more),  but the traditional \hangindent command doesn't work for this.  \documentclass{article}  \begin{document} \hangindent=1cm This line of text has a hanging indent that looks fine, as long as it is outside a list environment. \begin{enumerate} \item \hangindent=1cm This line is inside a list environment and doesn't have a hanging indent- how can I add one? \end{enumerate} \end{document}     How can I add a hanging indent within a list? The case of the bleeding monospace font! I'm wondering if there's any log which stores information about a particular program such as when the program has started and closed manually on Windows such as MS Word, or Chrome. Any ideas? To do a patch manually I must type this command   sudo ./playback_delete_data_patch.sh 09_delete_old_data_p.sql     There is a space just before the 09:   sudo ./playback_delete_data_patch.sh [space] 09_delete_old_data_p.sql   How can I run this inside a script?  There are also several other commands but this one is giving trouble. Stop sound from speakers when connecting headphones I guess this question already had the answer here but I can't find it.

Reading an Excel file in PHP I'm trying to read an Excel file (Office 2003). There is an Excel file that needs to be uploaded and its contents parsed.  Via Google, I can only find answers to these related (and insufficient topics): generating Excel files, reading Excel XML files, reading Excel CSV files, or incomplete abandoned projects. I own Office 2003 so if I need any files from there, they are available. It's installed on my box but isn't and can't be installed on my shared host.  Edit: so far all answers point to  and/or  about how to use it. Surjectivity of Composition of Surjective Functions Suppose we have two functions, $f:X\rightarrow Y$ and $g:Y\rightarrow Z$. If both of these functions are onto, how can we show that $g\circ f:X\rightarrow Z$ is also onto? Please help me prove this. I'm not sure how to apply the parallelogram law to the norm.
