Speed of object towards a point not in the object's trajectory? How do I create a dynamic key to be added to a JavaScript object variable Normal subgroups of $S_4$ Can anyone tell me how to find all normal subgroups of the symmetric group $S_4$?  In particular are $H=\{e,(1 2)(3 4)\}$ and $K=\{e,(1 2)(3 4), (1 3)(2 4),(1 4)(2 3)\}$ normal subgroups? Programs never open in foreground How can I make programs open in the foreground? Nautilus will open in the background, Remmina (the remote desktop program) also opens in the background. I have to click on the icon in the Launcher for it to come to the foreground. I would think any program that is invoked by any means would come to front, as it opens. It seems if one program invokes another, it will be in the background. If I click on any icons in the Launcher though, it will actually open in the foreground. How do you configure proxy settings in the Ubuntu Server or Minimal (CLI) versions using the terminal? "named" vs "that is named" I want to describe my business and want to refer to it in a sentence.  I am trying to say:      "In 2015 we established a business (that is) named X".   Intuitively, the "that is" part is redundant, and makes the sentence more cumbersome. But I cannot think of a reason why we should be able to drop the verb.  Is the version without the "that is" part grammatically correct? How can it be explained? How to blacklist kernel modules? It is common for public Wi-Fi access points to include login pages, even at times, when they’re free (i.e. Starbucks, many airports, hotels, etc).  I’m often in a situation where I’ll open up Chrome/Firefox, with and all my previously open tabs will start to reload.  If there is a wireless login redirection page, however, every tab is redirected and reloaded and the previous page is lost from history (and the back button won't return to it).  Is there any way to avoid or circumvent this behavior? I am wanting to find a latitude and longitude point given a bearing, a distance, and a starting latitude and longitude.  This appears to be the opposite of this question ().  I have already looked into the haversine formula and think it's approximation of the world is probably close enough.  I am assuming that I need to solve the haversine formula for my unknown lat/long, is this correct? Are there any good websites that talk about this sort of thing? It seems like it would be common, but my googling has only turned up questions similar to the one above.  What I am really looking for is just a formula for this. I'd like to give it a starting lat/lng, a bearing, and a distance (miles or kilometers) and I would like to get out of it a lat/lng pair that represent where one would have ended up had they traveled along that route. How do I connect to a MSSQL database using Perl's DBI module in Windows? Which singular names ending in “s” form possessives with only a bare apostrophe? Many questions already ask about this topic ( , , etc.) and their answers vary, but they always give exceptions to the apostrophe-s rule, for example:      6.24 The general rule for the possessive of nouns covers most proper nouns, including most names ending in sibilants."   Examples they give include Kansas’s, Ross’s land, and Jones’s reputation. Exceptions include Jesus’  and Moses’.  Which names does this apply to?  Is the Aeneas’  form correct, or is it Aeneas’s instead? How do I fix Google Chrome's latest new tab page? I've just updated to the latest Google Chrome Dev build, and they've changed from the annoying-but-ok new tab page to an ugly and less usable page.  On the old one, nine thumbnails was not enough, and now they've restricted it to eight.  There's an empty "Tips and Suggestions" box which I wouldn't want even if it had stuff in; they've added Recent Downloads - on the rare occasions when I need that, I'll hit Ctrl-J to open the Downloads tab; and the site-specific search box on the right has now gone!  Is there a way to get the old new tab page back, or a plugin to provide a superior one?   Update: I launch Chrome by pressing Win+R and entering "chrome" - I have a shortcut on the Path with a Target of "C:\Documents and Settings\&lt;user&gt;\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" --old-new-tab-page and whilst double-clicking this shortcut brings up the previous new tab page, using the keyboard method results in the old one.  How do I get it working via the Run box? (Without using a batch file, which slows things down too much.)  Update 2: GRRR! Now they've gone and stopped the --old-new-tab-page parameter from working at all! I hate this new version of the page that they're forcing upon us - can anyone provide a method to get rid of it and get the decent page back? Is reusing old code for a new assignment considered self plagiarism? How to protect yourself if you consider it to be, and a group partner does not? I am taking a graduate machine learning course and am working with another student in the class on a final project. In his undergraduate studies, the other student wrote code that accomplished a similar task, and mentioned in our previous meeting that we would be able to leverage much of this code for our current project if we wanted to. I responded that I believe it would constitute textbook cheating and self-plagiarism, but the other student disagrees and believes that re-using the code would not constitute self-plagiarism because he himself wrote it, and it would be redundant to re-write what he had already done.  Now, the course instructors have made it clear that we are not allowed to use any external libraries to perform certain classes of algorithms for this project. This students' prior code would fall under this category of prohibited tools, but he claims that it doesn't qualify because he wrote the code himself (so it is not an "external library"). I believe this is hyperbole, but he disagrees. It is also worth mentioning that this code is licensed under an , though it is not widely used at all.  It has gotten to the point where I am uncomfortable going forward with the project by re-using his old code, and he does not want to do work on the project that he considers to be redundant. My worry is that if it turns out we're not allowed to reuse the code, then using it could cause us to fail the course and severely negatively affect our reputations. Even if we don't get caught, I personally feel that it would be unethical to copy-paste old code and present it as though it's fresh code for this current project.  I am unsure of how to proceed. I have tried reaching out to the professor of the course some time ago (she has been traveling for some conferences recently and will be for a while) but I have not heard back from her. Additionally, the course TAs have been unwilling to weigh-in on the situation.  I have the following questions:   Is the above situation usually considered to be self plagiarism? Why or why not? Is the above act typically allowed in an academic setting? Assuming you are in my position, and consider re-using the code to be cheating and/or unethical, what is the best way to proceed; both in terms of how to make progress on the project, how to compromise with my group mate, and how to protect myself if my group mate refuses to budge. If a sports team is down by 1-2 in a best of 7 series, what is their chance of winning (if both teams have a 1/2 chance of winning every game)? I know that the team has to win 3 of the 4 remaining games. So I thought that from the 4 remaining games, there are a total of $2^4 = 16$ total different outcomes.   Could someone point me towards the right direction to determine the probability of the team winning 3 of the 4 remaining games? Would it be 4C3/16 since the three wins can be chosen amongst the 4 games left? Need help identifying short story about retired military colonel who fought war at end of time I read this story in an anthology in the eighties or early nineties.  It was about an old man who lived outside a western-like town, though that might have just been how I imagined it.  He goes to town and some ex-military thugs are there causing problems.  Flaunting some odd interdimensional military tech of some sort.  He doesn't want to intervene as doing so would be bad but in the end he must.     By intervening, his military identity is revealed and that causes him (some paradox or causality law) to have to go back and fight the war again.   The war is at the end of time or the universe.  The man is maybe a colonel of the sky something... Not much to go on; I have been searching my collection and wracking my brain for years trying to recall the story. "can't" versus "couldn't", what is the difference? That can't be Obama at the door, it's too early.  That couldn't be Obama at the door, it's too early.    What is the difference between them? Are they almost the same? I have an accompanied visa with my grandparents but because of some reason they cannot travel with me. I am above 17 years. Can I travel alone and will I be allowed to enter UK as my real aunt puts up there? Cannot reach public WIFI login page in Ubuntu 18.04 Captive Portal Issue 17.10 Super key to open applications The parmesan cheese in pasta recipe is quite expensive.....do we have cheaper alternative??  Are there are cheddar cheese which can replace parmesan cheese?
