Sometimes I'd like to discuss some ideas related to a question without including them in the comments. For (1) it gets too long and (2) often the discussion is quite specific and probably isn't relevant to others who come across the question.  Having the automatic "move to chat" feature when comments get too long is a great idea, but I think SO users should be able to pre-empt this and start a chat for a question, and maybe an answer too, manually.  For others who then come across this chat through another means than the question it'd be nice for them to know the context of the chat. I'd like to have an automatic explicit link between the chat and question created in such cases.
When comments get too chatty the move-to-chat feature asks if you'd like to move it out. But this often happens after the fact and thus doesn't prevent it.   I propose that:   Move-to-chat be provided as a button along side so that a user who knows their question or conversation may become drawn out may elect to preempt and take the conversation "off-line"
How do people understand astromech droids? Since Ubuntu 18.04 I can't drag a file e.g. image file to an open application such as Inkscape or  email message window. In Ubuntu 17.10 I was able to select the image file by clicking on it, and while holding down left mouse button I would hit the supper key displaying all open windows where for there I could then drop the file in any open app or folders. This is no longer possible/default behaviour since Ubuntu 18.04. Is there a workaround that would allow me to achieve this or even a way to recreate the same behaviour like in 17.10? Here is my problem: I've got a dialog with some parameters that the user can change (via a spinner for example). Each time one of these parameters is changed, I launch a thread to update a 3D view according to the new parameter value.  If the user changes another value (or the same value again by clicking many times on the spinner arrow) while the first thread is working, I would like to abort the first thread (and the update of the 3D view) and launch a new one with the latest parameter value.  How can I do something like that?  PS: There is no loop in the run() method of my thread, so checking for a flag is not an option: the thread updating the 3D view basically only calls a single method that is very long to execute. I can't add any flag in this method asking to abort either as I do not have access to its code. What does a two overlapping circles symbol mean in an electrical schematic/diagram? In the datasheet for a A3503 Hall Effect Sensor, I saw a circuit diagram labeled 'Functional Block Diagram', and it shows a symbol I have not seen before. It's shown here between 3 - Output and 2 - Ground.  What is this supposed to represent?    The full datasheet is available Is B1 visa in perfect condition valid on old damaged passport? I got my US B1 visa last month on my Indian passport. Someone in my family wrote a phone number on one of the blank page of my passport. As my passport is damaged now, can I travel with my current passport to US or I should apply for new passport? Also, will B1 visa be valid on old damaged passport if I get new passport? HTTP request parameters are not available by request.getAttribute() What is the behaviour of \fontsize if baselineskip is below a certain value? during my optimization process I found something spurious I cannot explain to myself and which I would like to understand. So with \fontsize you set the fontsize and the baselineskip. However the behaviour of the second paramater is a bit unclear to me, because if you reduce it too much, at a certain point the baselineskip gets bigger again. Let me show you my example: \documentclass[landscape]{article} \usepackage[margin=1cm]{geometry} \usepackage{lipsum,multicol}  \begin{document} \begin{multicols}{4}     \fontsize{10}{11}\selectfont     \lipsum[1]     \columnbreak          \fontsize{10}{10}\selectfont     \lipsum[1]     \columnbreak          \fontsize{10}{9}\selectfont     \lipsum[1]     \columnbreak          \fontsize{10}{8}\selectfont     \lipsum[1]     \columnbreak \end{multicols} \end{document}  If you compile this, your result will be looking like this:  Now from the first to the third column it seems logic, that the baselineskip is reduced and hence less space is needed vertically to typeset. But with the third column, even though the baselineskip is reduced even further, it needs more vertical space overall. It is strange however, that for example from line 11 to 12 (starting with tus and lum), the spacing seems to be narrower than in column 3, while in a lot of line the spacing is bigger. Changing the baselineskip to lower values down to 0 does not modify the vertical alignment further. What is the purpose of this behaviour and is it intended? I cannot see a benefit of this and I am a bit confused. Why is SQL Server losing a millisecond? I have a table structured like this:  CREATE TABLE [TESTTABLE] (     [ID] [int] IDENTITY(1,1) NOT NULL,     [DateField] [datetime] NULL,     [StringField] [varchar](50),     [IntField] [int] NULL,     [BitField] [bit] NULL )   I execute the following code:  BEGIN     INSERT INTO TESTTABLE (IntField, BitField, StringField, DateField)     VALUES ('1', 1, 'hello', {ts '2009-04-03 15:41:27.378'});       SELECT SCOPE_IDENTITY()   END   And then   select * from testtable with (NOLOCK)   and my result shows:  2009-04-03 15:41:27.*377*   for the DateField column.  Any ideas why I seem to be losing a millisecond?? I've just set up a new machine with Ubuntu Oneiric 11.10 and then run  apt-get update apt-get upgrade apt-get install git   Now if I run git --version it tells me I have git version 1.7.5.4 but on my local machine I have the much newer git version 1.7.9.2  I know I can install from source to get the newest version, but I thought that it was a good idea to use the package manager as much as possible to keep everything standardized.  So is it possible to use apt-get to get a newer version of git, and what is the right way to do it? Icon for pinned tabs in Safari? It would be nice to  for .  As it is, SE kind of stands out (in a not cool way): Cannot do a `composer install` even though my minimum stability is listed as dev I am trying to build the master branch in my project after updating to 8.5.0, but am being met with an error from composer (which I did not get on my develop branch):     The requested package drupal/focal_point 1.0.0-beta6 is satisfiable by   drupal/focal_point[1.0.0-beta6] but these conflict with your   requirements or minimum-stability.   In my composer file, I have:  "drupal/focal_point": "^1.0",   as well as:  "minimum-stability": "dev",   How can I fix this so TravisCI gets unstuck? It worked fine for the develop branch, and the master is now updated with it. Setting page numbering on Word I have a word document. The first four pages are title and index. After that, the “Chapter 1” starts. I want page numbers to begin from the “Chapter 1” onwards only. The first 4 pages should not have any page number.  How do I achieve this? Javascript variables keep track to their copies? I'm wondering if it's possible to hide a folder without renaming it with a dot on the Desktop.

English proverb for when a solution comes too late In Flemish we have a saying "Vijgen na pasen". Translated: "figs after Easter". It means a solution comes too late to be of any use.  What is the English equivalent for this?  Some googling gives me "Closing the barn door when the cow has bolted", but the explanation seems to point more towards the wrong solution for a problem. How to turn particle emission on/off? Is there a way to animate whether or not a particle emitter is emitting particles at a given point in time?  I'm using the particle system to animate bullets, so basically I'm trying to find a way to say: at frame 150 the gun fires a burst until frame 170, at frame 240 it fires a burst until frame 265, and so on.  I've tried key framing the particle render setting between "object" and "none", but the problem with that is that the hidden particles are still there, so when the render setting switches to "object", the particles that were initially hidden suddenly appear.  I've also thought of putting a plane (not rendered) with a collision modifier in front of the emitter and then moving it when I want the emitter to start emitting particles.  Is there a better way? How to correctly enable Desktop Cube in Unity 3D? Training on the full dataset after cross-validation? An irreducible polynomial of degree coprime to the degree of an extension is irreducible over this extension I'm having a hard time showing this:     If $K$ is an extension of $\mathbb{Q}$ with degree $m$ and $f(x)$ an irreducible polynomial over the rationals with degree $n$, such that $\gcd(m, n)=1$, then $f(x)$ is irreducible over $K$.   I have tried it by writing $f(x)=a(x)b(x)$ and then looking at the coefficients of those polynomials (some of them must belong to $K-\mathbb{Q}$ which could possibly result in a contradiction) to no success. I have no idea where to use the hypothesis of m and n being relatively prime.  Any help would be appreciated.
