Is there a portable version of Chrome for Ubuntu?
I read a book back in middle school. Can't remember the name of the book or the author or anything. Tried googling all the stuff I remember, but nothing ever fit it. It had a biohazard symbol on the cover, and it was sort of holographic, a bunch of whites and blues, looked kind of like how people interpret dream sequences or warp jumps in sci-fi animation or film. The book involved three kids, and they got a message one day or something, and they eventually decoded it to be lottery numbers, and they were told to buy a submarine with it and some other things. Some weird fog starts appearing all over the place, and these white creatures start beating up on everybody else. When they lose pretty much everybody, they're just kind of sitting in the submarine, and they send a message back in time, I think. It's been a few years. Anybody know what the book is or have any hints on it? Thank you~ Intraclass correlation coefficient vs. F-test (one-way ANOVA)? I'd like to "add to" an existing command by writing something like  \renewcommand{\somecommand}{\begin{something}\somecommand\end{something}}   but (not surprisingly) I get errors about being "too deeply nested".  Is there a way to take an existing command, add to it (by appending or prepending additional commands or text), and then have that "augmented" command replace the existing command? WCF - Faults / Exceptions versus Messages We're currently having a debate whether it's better to throw faults over a WCF channel, versus passing a message indicating the status or the response from a service.  Faults come with built-in support from WCF where by you can use the built-in error handlers and react accordingly. This, however, carries overhead as throwing exceptions in .NET can be quite costly.  Messages can contain the necessary information to determine what happened with your service call without the overhead of throwing an exception. It does however need several lines of repetitive code to analyze the message and determine actions following its contents.  We took a stab at creating a generic message object we could utilize in our services, and this is what we came up with:  public class ReturnItemDTO&lt;T&gt; {     [DataMember]     public bool Success { get; set; }      [DataMember]     public string ErrorMessage { get; set; }      [DataMember]     public T Item { get; set; } }   If all my service calls return this item, I can consistently check the "Success" property to determine if all went well. I then have an error message string in the event indicating something went wrong, and a generic item containing a Dto if needed.  The exception information will have to be logged away to a central logging service and not passed back from the service.  Thoughts? Comments? Ideas? Suggestions?  Some further clarification on my question  An issue I'm having with fault contracts is communicating business rules.  Like, if someone logs in, and their account is locked, how do I communicate that? Their login obviously fails, but it fails due to the reason "Account Locked".  So do I:  A) use a boolean, throw Fault with message account locked  B) return AuthenticatedDTO with relevant information Are smaller p-values more convincing? In my javascript I have this      loopDeLoop:         while (foo !== bar) {             switch (fubar) {                 case reallyFubar:                     if (anotherFoo == anotherBar) {                         break loopDeLoop;                     }                     break;                 default:                     break;             }         }   But JSLint says... lint warning: use of label  Here's the notes from        Labels   JavaScript allows any statement to have a label, and labels have a separate name space. JSLint is more strict.      JSLint expects labels only on statements that interact with break: switch, while, do, and for. JSLint expects that labels will be distinct from vars and parameters.   How do I construct the above to get rid of the warning?  Thanks, Greg How to roll perception checks for characters who aren't actively looking without arousing suspicion? This applies to all d20 systems, but with an example from the from the Pathfinder  (emphasis mine):  Stonecunning: Dwarves receive a +2 bonus on Perception checks to potentially notice unusual stonework, such as traps and hidden doors located in stone walls or floors. They receive a check to notice such features whenever they pass within 10 feet of them, whether or not they are actively looking.  In this case, does the GM roll the check in secret or ask the player roll the check? If the GM asks the player to roll for the check, what stops situations like:  GM: (interrupting) &quot;Gimli, Roll a perception check.&quot; Dwarf player: &quot;Oh, it's a natural one, I guess I don't see anything.&quot; Human player: &quot;Okay, I'll roll a perception check for anything unusual in this room. Nice! 19. How about 19, does 19 work for you?&quot; GM: &quot;Gimli, everything looks kosher to you. Aragon, you notice a rock coloured tarp on the ground here, covering what looks like a pit trap.&quot;  In this case, by telling the dwarf to roll his &quot;free&quot; perception check, he's telegraphed to the players that there is something to notice. How can this be fixed, without bluffing checks for nothing in particular to throw off the signal to noise ratio of similar checks? Mixed content on many SE sites Many SE sites (like math.SE) have a problem with mixed content, which causes display bugs in recent browsers. This is particularly evident with math.SE (because of the huge use of MathJax) and with chat sections.  Will this be fixed?

Star vs Heart icon to represent save as a favourite I am working on a mobile app that involves the user saving a favourite location. I wanted to use an icon to represent that feature, but I'm not sure which one is better – a star or a heart icon.  Some say heart icon tends to increase the rate of productivity, and some say they are used to a star icon to 'save' or 'bookmark' something.  What do go you guys think? Make hyperref take pdfinfo from \title and \author I once read about an option for hyperref that automatically takes the info provided via the standard \author and \title, and puts it into the pdfinfo. Now I want to implement it in my template and can't find it anywhere in the hyperref manual nor anywhere else.  Did I dream about this or can someone help me out here?

Trouble With Persistence After Making a USB Live Thumb Drive Using Pendrivelinux I created a bootable Ubuntu on my 32GB thumb drive (on a NTFS partition) and I selected a persistence of 4GB.  I've noticed that when I reboot from the initial booting off of the USB thumb drive, nothing is preserved.  No apps that were installed nor saved bookmarks.  Is there a way for me to manually force persistence? Continuing example in Beamer
