Find out trace of a given matrix $A$ with entries from $\mathbb{Z}_{227}$ Let $A$ be a $227\times 227$ matrix with entries in $\mathbb{Z}_{227}$ such that all of its eigen values are distinct. What would be its trace? I think it is zero by adding all 227 elements but i am not sure.  Edited: Here I have assumed that eigenvalues are in a base field. Where is the Layers panel in Blender 2.8? What does this red icon on my panel mean? This red icon.... It showed up after I upgraded to Ubuntu 12.04LTS; I can't figure out how to ditch it. It seems to be a notification thing.  I am at a loss.  The icon is this one:      I clicked it and read this:     An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was:  'Error: BrokenCount&gt;0'.        This usually means that your installed packages have unmet dependencies. I currently have a 75% credit utilization, which I know is not favorable on about 35,000 revolving credit.  I am getting my year end bonus and plan on using that to completely pay off all of my credit cards leaving me with a 0% credit utilization.  Currently my credit score is 668, mostly due to my utilization, I pay everything on time, but just have too much debt, which is why i'm paying it all off.  My question is how much will paying off all my revolving credit and having a 0% utilization on 35,000 credit availability positively effect my credit score? How to open a file manager of the current directory in the terminal? When I work in terminal, sometimes I want to open the current directory in a GUI file manager. And then to click the items in the window to run the application. How can I do this? Conditional Formatting: 3 color scale showing text relevance in Excel for Mac Is there a way to use conditional formatting in the following manner in Excel? (For those who are curious, I am using Excel 2010 for Mac)  I want Cell B2 to be green when A2 says "John likes green apples" and B2 also says "John likes green apples", yellow if A2 says "John likes green apples" and B2 says "Bill likes blue apples", and red if A2 says "John likes green apples" and B2 says "Bill hates red oranges".  I am just wondering if there is a way to something to that effect.  Thanks I cleared all my browser data and visited  and it logged me back in. How?  This happens on Chrome on OS X and Windows 7.  Surely the security concerns outweigh the benefits to the user. What if a family member or friend wants to use my machine? I wouldn't want them logged in as me.  Update  My mistake, I should have said data &#8212; all those checkboxes clicked/checked. I completely cleared everything, yet it still logs me back in.  Update 2  Here's a video to prove it: How do I change NEI to cheat mode? When I heard that you could look up recipes and cheat items with Not Enough Items, I downloaded NEI. It worked, and then I got another mod and the all of a sudden NEI still worked, but it was locked in recipe mode only. I tried fixing it by putting it into cheat mode again, but it was still in recipe mode.  I knew the only reason this happened was probably because of a change in the mod. Then I was watching a YouTuber who had the same exact mod as me and NEI was working and not locked in recipe mode for him. I tried redownloading NEI and getting it again but I was still stuck in recipe mode.  How do I get NEI in cheat mode? How can I send a custom desktop notification? I have a custom script and I want to send a desktop notification (the one that appears in the top right corner of the screen) with a custom message. How do I do that? What is the difference between operator "=" and "==" in Bash? Prevent href="#" link from changing the URL hash How do I address unchecked cast warnings? Eclipse is giving me a warning of the following form:     Type safety: Unchecked cast from Object to HashMap   This is from a call to an API that I have no control over which returns Object:  HashMap&lt;String, String&gt; getItems(javax.servlet.http.HttpSession session) {   HashMap&lt;String, String&gt; theHash = (HashMap&lt;String, String&gt;)session.getAttribute("attributeKey");   return theHash; }   I'd like to avoid Eclipse warnings, if possible, since theoretically they indicate at least a potential code problem.  I haven't found a good way to eliminate this one yet, though.  I can extract the single line involved out to a method by itself and add @SuppressWarnings("unchecked") to that method, thus limiting the impact of having a block of code where I ignore warnings.  Any better options?  I don't want to turn these warnings off in Eclipse.  Before I came to the code, it was simpler, but still provoked warnings:  HashMap getItems(javax.servlet.http.HttpSession session) {   HashMap theHash = (HashMap)session.getAttribute("attributeKey");   return theHash; }   Problem was elsewhere when you tried to use the hash you'd get warnings:  HashMap items = getItems(session); items.put("this", "that");  Type safety: The method put(Object, Object) belongs to the raw type HashMap.  References to generic type HashMap&lt;K,V&gt; should be parameterized. Number Theory: Prove that $m | \phi(a^m - 1)$ How can I use adb to send a longpress key event? How to reverse a user input without using array or any library function(any function for reversing)? I'm having trouble understanding the wording of one of my homework questions. Since this question appears early in the chapter, I have a feeling that I'm misinterpreting it.  Give a finite automaton that that accepts the following language: The language over $\{a, b\}$ of any even number of $a$'s and any odd number of $b$'s.   I'm having trouble with the usage of "and". Is it asking for an FA that accepts any string that is either an even number of $a$'s or an odd number of $b$'s, e.g. $aa$, $bbb$, $aaaa$, etc, but not accept strings like $aabbb$, $abbab$.   Or, is it asking for an FA that accepts any string that contains an even number of $a$'s or an odd number of $b$'s, e.g. $aabbb$, $ababb$, etc.   The first case is relatively simple, but I've been struggling with the second. I haven't even managed to convince myself that it is a regular language (because I haven't been able to come up with a regular expression that matches it).   My questions: Which interpretation seems most likely. Is the second case a regular language, if so, give a regular expression that recognizes it. When do I use "I" instead of "me?" From some comments in the answers for  (now deleted, 10k only), there's confusion around the usage of I vs. me:  While the sentence, "the other attendees are myself and Steve," is agreed to be incorrect, there's confusion about whether the correct form is "the other attendees are me and Steve" or "the other attendees are Steve and I."  (I've always used the heuristic of removing the other people from the sentence, so I always thought "the other attendee is me" would be correct, instead of "the other attendee is I." Is this true, or am I using a flawed heuristic?)
