Clarification regarding self
When is "self" required?
Vertical line for the the right margin in Notepad++ Does anyone know if Notepad++ can display a vertical line on the right margin to indicated that the text will or will not fit on a printed page?  I have looked but I cannot find it.  Word wrap does work, but it wraps by my screen width, not by the width of a printed page. My question is specifically for badges in a particular tag. I've heard that the rules have been changed.  How and when can one get bronze, silver and gold badges for a specific tag, say ? What are the new rules governing these badges? Select Permissions Across Multiple Schemas Within the Same Database I have been asked by a client to implement some views for reporting purposes, the views will be accessed via PowerBI, Excel and SSRS. The designated user will only have access to the view and no underlying tables must be available to the user.  The problem I have encountered in that the SQL within the view touches 3 different schemas (All within the same database):   Pupil Provider  Security   The view is:  CREATE VIEW dbo.vTestPermissions AS SELECT a.Column1,        b.Column1,        c.Column1 FROM Pupil.Table1 a JOIN Provider.Table2 b ON a.Column1 = b.Column1 JOIN Security.Table3 c ON a.Column1 = c.Column1   The owners of the Tables/View are as follows:   Pupil.Table1 - Owner Pupil Provider.Table2 - Owner Provider Security.Table3 - Owner Security vTestPermissions - Owner dbo   When I select from the view I get an error:     The SELECT permission was denied on the object 'table3', database   'TEST', schema 'Security'   I have tried giving SELECT permission with and without the GRANT option to the schema, and the tables, but that makes the underlying tables available to the user.  Any help on this will be greatly appreciated. This is a silly question but under what conditions is $a^{xy}=(a^x)^y$ true, given all are complex numbers? Assuming I have a Czech license and break a minor law in Germany which incurs me a certain number of "violation points" (e.g. speeding), would those points be eventually transferred to my Czech license? I would obviously have to pay the fine (either on the spot or by mail), but it's not clear if EU countries exchange data on traffic points.  I would limit the scope to EU/EEA license holders driving within the EU/EEA, to avoid an overly broad question. Also assume that the person in question is resident in his home country and is only visiting other EU/EEA countries as a tourist. iOS: Your passcode is required to enable Touch ID When I open the file in Vim, I see strange ^M characters.  Unfortunately, the world's favorite search engine does not do well with special characters in queries, so I'm asking here:   What is this ^M character? How could it have got there? How do I get rid of it? PSN sharing games I buy &amp; download a game from PSN on my user account on PS3 #1. Then I switch to PS3 #2 and login with the same PSN account. Can I download the same game without paying twice? Etymology of "cut someone some slack" Teenagers. All the literature tells you one thing and one thing only – that  whatever they are doing, give them a break, cut them some slack, it's normal.      From the novel, Apple Tree Yard   I'm curious about the origins of . I know slacks are American English for trousers or pants, and a slacker is a lazy person. But what is a slack and how does one "cut" it? FFmpeg - Apply blur over face What do we mean when we say "for all n where n is an element of..." When we write "for all n where n is an element of A, P(n) is true." do we mean for all n, if n is in A then Pn or for all n, n is in A and Pn? Showing group with $p^2$ elements is Abelian I have a group $G$ with $p^2$ elements, where $p$ is a prime number. Some (potentially) useful preliminary information I have is that there are exactly $p+1$ subgroups with $p$ elements, and with that I was able to show $G$ has a normal subgroup $N$ with $p$ elements.   My problem is showing that $G$ is abelian, and I would be glad if someone could show me how.   I had two potential approaches in mind and I would prefer if one of these were used (especially the second one).   First: The center $Z(G)$ is a normal subgroup of $G$ so by Langrange's theorem, if $Z(G)$ has anything other than the identity, it's size is either $p$ or $p^2$. If $p^2$ then $Z(G)=G$ and we are done. If $Z(G)=p$ then the quotient group of $G$ factored out by $Z(G)$ has $p$ elements, so it is cylic and I can prove from there that this implies $G$ is abelian. So can we show theres something other than the identity in the center of $G$?  Second: I list out the elements of some other subgroup $H$ with $p$ elements such that the intersection of $H$ and $N$ is only the identity (if any more, due to prime order the intersected elements would generate the entire subgroups). Let $N$ be generated by $a$ and $H$ be generated by $b$. We can show $NK= G$, i.e every element in G can be wrriten like $a^k b^l $. So for this method, we just need to show $ab=ba$ (remember, these are not general elements in the set, but the generators of $N$ and $H$).   Do any of these methods seem viable? I understand one can give very strong theorems using Sylow theorems and related facts, but I am looking for an elementary solution (no Sylow theorems, facts about p-groups, centrailzers) but definitions of centres and normalizers is fine. Unable to forward search Bash history similarly as with CTRL-r Why does the road look like it's wet on hot days? Often, I'll be driving down the road on a summer day, and as I look ahead toward the horizon, I notice that the road looks like there's a puddle of water on it, or that it was somehow wet. Of course, as I get closer, the effect disappears.  I know that it is some kind of atmospheric effect. What is it called, and how does it work? If you know the Index, Value or Text. also if you don't have an ID for a direct reference.  ,  and  are all helpful answers.  Example markup  &lt;div class="selDiv"&gt;   &lt;select class="opts"&gt;     &lt;option selected value="DEFAULT"&gt;Default&lt;/option&gt;     &lt;option value="SEL1"&gt;Selection 1&lt;/option&gt;     &lt;option value="SEL2"&gt;Selection 2&lt;/option&gt;   &lt;/select&gt; &lt;/div&gt; Suppose that a deck of 52 cards containing four aces is shuffled thoroughly and the cards are then distributed among four players so that each player receives 13 cards. Determine the probability that each player will receive one ace.   The answer to this is given as$$\frac{13^4}{\binom {52}4}$$  My doubt is the following:   The book justifies ${\binom {52}{4}}$ as number of possible different combinations of the four positions in the deck occupied by 4 aces. That sounds like a case of arrangements to me, so shouldn't we think about permutations and not combinations if we are concerned about how the aces are to be arranged in the deck ?. Shouldn't the denominator be ${\binom {52}{13}}$ since you are choosing 13 cards for 4 people. The Node Editor won't work for the object selected I'm writing a script which shows the git log for a directory when I cd into it. Such a log can be overwhelming, containing hundreds of lines. So far I have been limiting that to a hard-coded 20 lines (... | head -n 20), which is fine on the screen at work, but too much on the smaller MacBook screen at home.  I would prefer the log to take up about half the (vertical) screen on either terminal. And "terminal" also changes: it's Gnome terminal at work, but iTerm2 at home. And I do not use screen or tmux.  How do I find the number of vertical lines available in a terminal from command line? What's the reasoning behind the delete:1 restriction for only content I own? I recently reached 10k reputation on Stack Overflow, and noticed that I now have the ability to view deleted posts with deleted:1 via the search bar. I'd like clarification as to why the restriction exists that prevents me from searching through all deleted posts?  I feel like this would be beneficial for several reasons:   , a bot that was designed to detect spam,  to help fight spam. Having deleted:1 as an option could offer a second link to show the amount of true positives, to determine if it's worth adding to a blacklist. In , the domain v-play.net was deemed as "Too many FP's". Having a check to see how many TP's there may be, may outweigh the number of false-positives, and would give a better view. Bots are currently unable to view deleted posts through the API (Even if the linked user account/API user has >10k reputation). I think that this is partially because of this restriction. I had brought it up , because I thought that having SmokeDetector log a (non-caught) rude/abuse or spam posts would be beneficial, so that we could adapt our methods to catch these types of posts in the future.  was posted earlier today. I remembered it was similar to another post I came across, but was unable to find it because . Being able to search deleted posts would have allowed me to catch this behavior, and bring it up to the mods (I was lucky that someone else had a link for it, and we were able to advise the user what to do in the future). As a member of , I come across a lot of posts that are borderline spammy (via ) which I have a vague recollection of seeing before. Instead of flagging as spam, I usually vote NAA as to not nuke a user, but by being able to search deleted posts for that user, I can see if he is habitually continuing to post links to his product/service, and flag for custom moderation attention in case.   Overall, I think it would add a lot more visibility that could be helpful in bringing problematic issues to dimaond moderator attention, something that was specifically mentioned in :     Make sure what is being deleted should have been deleted, and bring unnecessary or harmful deletions to the attention of the community and/or moderator team.   Additionally, I think that deleted:1 is almost useless in the current state it's in. If the restriction exists that I can already view my own deleted posts, why shouldn't it be available to all users (If it's limited to one's self), as I can already view my own deleted posts? I have read lots of information about page caching and partial page caching in a MVC application. However, I would like to know how you would cache data.  In my scenario I will be using LINQ to Entities (entity framework). On the first call to GetNames (or whatever the method is) I want to grab the data from the database. I want to save the results in cache and on the second call to use the cached version if it exists.  Can anyone show an example of how this would work, where this should be implemented (model?) and if it would work.  I have seen this done in traditional ASP.NET apps , typically for very static data.
