Answers I want to describe a sad situation that I encountered here recently. I joined a subcommunity "Russian language" cause I am interested in linguistics and had some experience of working in a Russian language magazine as an editor.  So I posted some replies and got a comment that they are bad and too broad and pretty harsh commands in a style "do this, don't do that" from some of the old-timers here. Anyway I disagreed and said I was probably right and had some experience (maybe that was wrong to say). After that this guy started insulting me implying that I lie about my previous work and telling that his 4-year exp. here matters much more! Then we had a bit of unpleasant talk and later he deleted ALL his comments in it.  That was all a bit rude, but no problem, maybe my answer was a bit broad, I admit that. Bad things started later. He started putting minuses to all my answers (moreover 2 minuses at a time) and told me that he would do it further cause I "don't understand in a good way".  But I really wanted to take part in this community. I wrote to moderator using a standard form, but got no reply. (maybe he is a moderator himself?)  What should I do? I don't want to have all my answers minused (with 2 minuses at the same time - dunno why) Here he threatens me to "control" all my answers -  (sorry it's in Russian) Here he "controls" them -   Sorry about that question, I don't want to have quarrels or drama, just want to have friendlier attitude and not being minused cause someone dislike me personally. Whom should I contact about it if moderator option doesn't work?
While browsing Stack Overflow, I noticed that I lost a lot of reputation:        Is this serial downvoting? Will it be corrected by a rep-recalculation? How often are those done?    Here's a second instance:
I am struggling with this question from Halmos's text, please ignore the imperative language.  "Suppose that $L, M$  and $N$ are subspaces of a vector space. Show that the equation    $$L \cap (M + N) = (L \cap M) + (L \cap N)$$   is not necessarily true.  Since each of these subspaces has origin in them, clearly there intersections could not be empty. I wasn't able to formulate an example where this result did n't hold. Any help would be highly appreciated. Integral of $\frac{\sqrt{x^2+1}}{x}$ So I have to do the integration of $\frac{\sqrt{x^2+1}}{x}$. Give me a hint. What should I replace? Should I do it with integration by parts? How to eliminate Cycles artifacts with many overlapping volumes? I have encountered an issue with Cycles Volumetrics in a recent scene. I am using Blender 2.72, and both CPU and GPU render options. In both I get a solid black artifact when I have two volumes overlapping, as in this campfire smoke test:    I have a solid cube, with a volume scatter and volume absorption material, duplicated by a particle system. As you can see, when the particles get higher up and farther apart, and are no longer overlapping, the artifacts disappear. Title is removed/cleared/erased when starting editing How can I speed up combat with a large number of enemies? I'm DMing for a campaign where the player characters will sometimes face small squads of creatures, most recently six ground troops and two archers helping out. In this setting, these creatures dominate the land the PCs are in and have an organised military, hence squads of enemies.  Combat tends to go quite slowly, however. Eight enemies and three players means the players spend a lot of time waiting between their turns!  Without reducing the number of enemies in the encounter, how can I speed up combat when the players are fighting many enemies? Who can see what in my profile? When editing my user profile (name, date of birth, etc.), how can I tell which information can be seen by other users (publicly visible) and what is only used by the system (and how it's used)? How do I use sudo to redirect output to a location I don't have permission to write to? Programmatically close aspx page from code behind What is the best way to close an ASPX page from the code-behind?    I have a button event handler that I want to close the page after the user has clicked an ASP.NET button on the page.  I have tried to programmatically add a JavaScript method that contains a window.close() command to the OnClientClick event to close the page but it does not work.  The button is also a asp:AsyncPostBoskTrigger for an AJAX Update Panel.  The application uses .NET Framework 3.5. Word for "things which exist" Why don't the colonists wear spacesuits in Alien: Covenant? In the beginning of the Alien: Covenant movie, a group of colonists from the main ship make a landing on an unknown planet, which they found out accidentally after ship has been bombarded by an unknown wave from a star collapse and what bothers me, is that they don't wear any spacesuits, any protective gear, any air filter systems, just nothing.  Is that really the way future space expeditions gonna explore new possible planets presumed as possible habitable homes for humanity?  Every 5th grader knows, from the biology school lessons, that water, air, and even earth itself contains and gives life to a thousands of viruses, bacteria, and microorganisms.  You can breathe in bacteria, or virus, and be dead in a seconds.  Do film makers really suppose we will take it as realistic depiction of extraterrestrial expedition?   Reality check just screams out loud.  What do you think can be their motivation for such a decision? Were there any improvements to the second Death Star (other than the change in exhaust port) that we know of? We know that the second Death Star was meant to have a different/non-existent exhaust port and when under construction it had a shield projected around it.  Other than these elements, one of which was planned to be totally temporary, do we know of any other improvements over its predecessor?  Did it have improved defences against one-man fighters? Did its laser charge more quickly? Did it have an upmarket cafeteria? Let $\alpha(t)$ be a regular curve. Suppose there is a point $a$ in $R^3$ such that $\alpha(t)-a$ is orthogonal to $T(t)$ for all t. Prove that $\alpha(t)$ lies on a sphere.  So, I let $\alpha(t)=(x(t), y(t),z(t))$ and $a=(a,b,c)$.  Since, $\alpha(t)-a$ is orthogonal to $T(t)$,  $&lt;\alpha(t)-a,T(t)&gt;=0$.  But I don't know how to solve this.. How can I prevent URLDownloadToFile from retrieving from the cache? I am using URLDownloadToFile to retrieve a file from a website. Subsequent calls return the original file rather than an updated version.  I assume it is retrieving a cached version. php sort associative arrays by keys that those keys exist in other array Strange bug with "MessageName[a,b] is not of the form symbol::name ", Debugger & cursor location I want to start a modal operator by clicking a button in a panel in the properties region. It should then stop when I click somewhere in the 3D viewport. I want to execute some code when I start and finish the operator (see the code below). I tried modifiyng the modal operator template with an execute method to start the modal operator. But the now the context.space_data.type is always &quot;PROPERTIES&quot; because that's where the panel is located, I guess. Is this a bad way of doing what I want? class MY_OPERATOR_OT_click_on_3dview(bpy.types.Operator):          bl_idname = &quot;mesh.click_on_3dview&quot;     bl_label = &quot;Click on 3D&quot;      def modal(self, context, event):                  if context.space_data.type != 'VIEW_3D':             return {'PASS_THROUGH'}                  if event.type in {'MIDDLEMOUSE', 'WHEELUPMOUSE', 'WHEELDOWNMOUSE'}:             # allow navigation             return {'PASS_THROUGH'}         elif event.type == 'LEFTMOUSE':             # DO ALL THE POST-SELECT STUFF             return {'FINISHED'}         elif event.type in {'RIGHTMOUSE', 'ESC'}:             return {'CANCELLED'}          return {'RUNNING_MODAL'}      def execute(self, context):         # DO ALL THE SETUP STUFF           context.window_manager.modal_handler_add(self)              return {'RUNNING_MODAL'}            def cancel(self, context):         print(&quot;CANCEL???&quot;) In Italian, when I write a sentence about an action (e.g. eating fish, playing), I would use the infinitive, such as  mangiare pesce fa bene alla salute (which literally is "to eat fish is healthy"), or giocare aiuta ad imparare (which literally is "to play helps to learn").   I would use the gerund in giocando si impara, but that would roughly mean "When playing, you learn." and in this case the infinitive would not be correct. (Giocare si impara is not what you would say in Italian.)  Should I use the infinitive, or the gerund, in sentences similar to the following ones?   To play with fire is dangerous. To win the lottery is just a matter of luck. To escape from Alcatraz is impossible. To practice makes you perfect.   Is the infinitive always wrong, when the verb is the subject of a sentence? Find the cardinality of the quotient of $\mathbb R$ in respect to R R is an equivalence relation defined as $xRy \Leftrightarrow a - b$ is an integer.  What is the cardinality of the quotient of $\mathbb R$ in respect to R? How would you prove it?  I thought about a bijection between $[0,1)$ to the quotient of $\mathbb R$ in respect to R, but can't figure out to prove it formally. How to fix task manager memory column if it shows lies I have a problem in showing memory in task manager with memory and paging columns. Why it shows so small size usage? And maybe anyone knows how to fix it?  Here is a screenshot(working set, memory, page pool) sorted by most consuming: I have a Surface Pro 4 and an iMac (late 2019). I would like to connect my Surface Pro to the iMac to use the iMac screen as a second monitor.  Is that possible?  What are the requirements to use an iMac as a second screen?
