Understanding why this is a complete sentence: 'Not happy or content.' I'm perplexed why the grammar check considers this a grammatically complete sentence:  Not happy or content.  To me, it's missing both a subject and a verb.  Could someone shed some light on this for me? Thanks.
Verbless sentence I thought I heard my teacher said: 'Don't construct a sentence without a verb.'  Is there such rule in english grammar?     She looks like 70 years old. Perhaps older.   How about the question above? Is it correct? Is there any book that can be used references for wide range of topics in grammar(including syntax, morphology et cetera)? I have finished oxford grammar in use recently and think it wasn't enough for me.
Java: Detect duplicates in ArrayList? How could I go about detecting (returning true/false) whether an ArrayList contains more than one of the same element in Java?  Many thanks, Terry  Edit Forgot to mention that I am not looking to compare "Blocks" with each other but their integer values. Each "block" has an int and this is what makes them different. I find the int of a particular Block by calling a method named "getNum" (e.g. table1[0][2].getNum(); Change HTML Produced by wp_list_comments() I am developing a WordPress theme for which I would like each comment's timestamp wrapped in in a &lt;span&gt; element for the sake of styling it with CSS rules. However,  as I use it in my theme's comments.php template does not seem to provide options to alter the HTML produced:  &lt;ol class="comment-list"&gt;     &lt;?php         wp_list_comments( array(             'style'       =&gt; 'ol',             'format'      =&gt; 'html5',             'short_ping'  =&gt; true,         ) );     ?&gt; &lt;/ol&gt;   which produces timestamps as such:  &lt;time datetime="2015-12-21T19:09:49+00:00"&gt; december 21st,  2015 on 19:09 &lt;/time&gt;   How can I alter the function's output to include a &lt;span&gt;element around each &lt;time&gt; element without altering core files?  I've tried looking at my theme's functions.php, as well as WordPress wp-includes/comment.php and wp-includes/comment-template.php. None of them deal with the actual tag structure of the comment timestamps generated by wp_list_comments(), so there was nothing there for me to play with. I'm searching for a template which makes a document look like it's written with a real typewriter. Ideally, this means it's not only in mono-spaced font, but the hyphenation is adjusted accordingly. Also, some randomness would be nice (e.g. some characters more bold than others), so that it looks more natural. piping in real time This is more a conceptual thing than a current problem.  Would it be possible to do this:  tail -f &lt;file&gt; | grep "string" | sed 's/stuff//g' &gt;&gt; output.txt  The problem I'm thinking is that tail -f never terminates so it won't progress in the command. I'm trying to read and output a file in real-time. If this doesn't work how would I do it? Are there regional distinctions in how hiccup/hiccough is spelled? Of course preventing them from getting stolen is the top priority, but invariably, someone is going to get jacked. What are some good practices to minimize the damage incurred when your PC is stolen?  Given most of our PCs contain our entire lives, its frightening to know that all this information can be in someone else's hands.   Some ideas i had (a bit paranoid, i admit).   keep encrypted backups.  Use truecrypt to have double encrypted (with strong password) volumes where you store your personal data. schedule Eraser to run every evening so that potential thieves couldn't undelete (and subsequently retrieve) sensitive data do all your banking in a virtual machine.  Keep the virtual machine volume encrypted, and on a portable usb drive that you carry with you / keep in a safe. have applications that phone home (or hit something to leave an IP trace) upon connection to the internet (can someone suggest a good solution for this?)   Does anyone have any other suggestions? I'm new to Blender and am having a few hitches.  Each time I use box select on a group of vertices it extends the selection from what was previously selected.  I can avoid this by hitting A to deselect all before using Box Select but I was hoping there was a way to have this happen by default.  Isn't it the desired workflow to select groups of objects and move them independently and only extend the select with Shift?  I must be doing it wrong. How to set Google+ photos to be Public-Unlisted (as you could do with PicasaWeb)? Previously, if I uploaded photos from Picasa to PicasaWeb, I could specify them as Public but Unlisted. So you had to have the link to view them but no login was required.  I don't see that option now that Picasa uploads to Google+.  Any ideas? I've been using mkvmerge to merge a video file and subtitles, I'm using the following command  mkvmerge -o output.mkv video.mp4 subtitles.srt   Which is working fine but as you can probably guess this is really slow operation   I've to open terminal in every one of those directories where movies are stored. Then I've to copy and paste the names of the files in the command Then I've to rename the output file Then delete the original files which I used   This is a lengthy process.     Ideal situation that I want.   I'll go into the folder which contains a movie file and a subtitle file with the same name. I select a movie file and and a subtitles file, right click and run a nautilus script on them. They get merged Original file gets deleted. Rename the merged file with the name of the orignal file with mkv extension      This doesn't need to be recursive, I don't want my HDD creating and deleting 100's of files at ones. Movie files and Subtitle files generally have the same name but some times have "_en" post fixed to subtitle files. If you have another approach of doing it I'm on board with that too. There is no continuous injective function $f:\mathbb{R}^n\longrightarrow\mathbb{R}^m$ I have the following question, more general that   Let $U\subset\mathbb{R}^n$ be a domain. If $f:U\longrightarrow\mathbb{R}^m$  ($m&lt; n$) is a continuous function, how to prove that $f$ is not injective.  Any hint would be appreciated. I created a partition for Ubuntu so I could dual-boot Windows Vista with it. However, Windows is no longer necessary and I want Ubuntu to take up the entire hard drive. I was wondering how to safely resize the Ubuntu (11.10) partition and take Windows out all together, without having to reinstall Ubuntu and lose all of the files. Why should one use EM vs. say, Gradient Descent with MLE? Mathematically, it's often seen that expressions and algorithms for Expectation Maximization (EM) are often simpler for mixed models, yet it seems that almost everything (if not everything) that can be solved with EM can also be solved with MLE (by, say, the Newton-Raphson method, for expressions that are not closed).  In literature, though, it seems that many favour EM over other methods (including minimization of the LL by, say, gradient descent); is it because of its simplicity in these models? Or is it for other reasons? Finding an example of a discrete-time strict local martingale. How to add a guest account without a password? How to prove the property of the Lemoine point of a triangle? I have a Godox X2Tc and a Godox X1Rc. I want to control my Canon Speedlite 430 EXII. (I also have a Godox V1, which is a beautiful thing!) I have the Canon Speedlite attached to the Godox receiver, so it should fire. It just wont! How do I set it up correctly so the receiver makes the Canon Speedlite fire?  Update: Michael C answered this question. I had the ID numbers set differently on the transmitter and receiver. I made them the same and now it all works. Perfect! Thanks Michael!! Everybody knows :-) that in Windows plain text files lines are terminated with CR+LF, and in Unix&amp;Linux - with LF only. How can I quickly convert all my source code files from one format to another and back? I am writing my thesis,  and i am in restructuring phase - sorting theorems where they should belong thematically. And it would be helpful to have all the proofs hidden so i am not laden with the additional information.  Is it possible to add something like hideproof to documentclass options to omit them when compiling the latex file. Conditional sentences not starting with "if" Were I rich, I would live on Long Island.   If I were rich, I would live on Long Island.   Is the first sentence still used, or is used in particular contexts (in example, to give emphasis to the sentence)? How can I abort a running JDBC transaction? Is there a way to prematurely abort a transaction? Say, I have sent a command to the database which runs five minutes and after four, I want to abort it.  Does JDBC define a way to send a "stop whatever you are doing on this connection" signal to the DB?
