As noted in  (similar, but not duplicate), Obi-Wan did know that Anakin was not dead, and that he was, in fact, Darth Vader. In , it is clear that the fact that Anakin was Darth Vader was not common knowledge at all.  So when how did Obi-Wan know Anakin had become Darth Vader? I don't recall reading any EU novels with any interaction between them.  Did he know at the time of their duel on Mustafar that Anakin was called 'Darth Vader'? If so, then he simply would have heard about Vader in other events and this is a dumb question
Obi-Wan left Anakin for dead, and one movie later (in A New Hope) he was saying Anakin had been killed by Darth Vader.  What exactly did Obi-Wan know about Anakin and Darth Vader before A New Hope started?
How do I disable the screensaver/lock? When I'm watching a film in Mythtv the screen turns to black every 10 - 15 mins and I have to log back into Ubuntu. Very annoying!  How do I disable the black screen / screensaver / logout in Unity?  There no longer seems to be any options to turn the screen saver off as there were in Ubuntu prior to Unity. Let $G = (\mathbb{C} - \{0\}, \cdot)$, a subgroup $U = \{x+yi \mid x^2 + y^2 = 1\}$. Use the Fundamental Theorem to show that $G/(\mathbb{R}_{&gt; 0},\cdot)$ is isomorphic to $U$ where $\mathbb{R}_{&gt; 0}$ denotes the positive reals.  I am struggling to find the correct mapping from $G$ to $U$ that results in the the kernel being the nonnegative reals under multiplication. I'm hoping to get help with this mapping then I can show it is a homomorphism and onto and can use the Fundamental Theorem. Is there a standard delay for consumer ratings of apps on the App Store? I have an app that's been out for a couple of weeks. Its not exactly selling like hot cakes yet, but I'm pretty sure I've gotten a rating or a review by now. But nothing shows when viewing either in iTunes or directly on the AppStore on the iPhone.  Is there a standard delay as to when ratings/reviews show up, that Apple imposes, especially for new apps? Or do you think there is some problem with Apple's system? If $f: D(0,1)\to \mathbb C$ is holomorphic, then there is a sequence $\{z_n\}$ in $D(0,1)$ such that $|z_n| \to 1$ and $\{f(z_n)\}$ is bounded Today I upgraded to the Creators Update by running setup from the ISO mounted locally. When I got back to my computer I opened Task Manager and saw my memory usage was a lot higher than it was previously (it's now almost 6GB memory usage at idle after logging in instead of 2-3GB with the previous Windows build) - the processes tab revealed that there were upwards of 60 different instances of svchost.exe running. This 6GB figure is just for process memory - not including memory used for caching or "standby".  I ran tasklist /svc to get a listing of which services were in which processes and it lists almost every svchost.exe instance as only having one running service contained within (with the exception of a handful of instances that are running a few system services).  Here's  my output:  Image Name                     PID Services ========================= ======== ============================================ System Idle Process              0 N/A System                           4 N/A smss.exe                       440 N/A csrss.exe                      612 N/A wininit.exe                    700 N/A csrss.exe                      708 N/A services.exe                   776 N/A lsass.exe                      784 KeyIso, Netlogon, SamSs, VaultSvc svchost.exe                    888 PlugPlay svchost.exe                    908 BrokerInfrastructure, DcomLaunch, Power,                                    SystemEventsBroker fontdrvhost.exe                936 N/A svchost.exe                   1000 RpcEptMapper, RpcSs svchost.exe                    104 LSM winlogon.exe                   544 N/A fontdrvhost.exe                420 N/A svchost.exe                   1072 DeviceInstall dwm.exe                       1136 N/A svchost.exe                   1164 BFE, CoreMessagingRegistrar, MpsSvc svchost.exe                   1424 lmhosts svchost.exe                   1432 W32Time svchost.exe                   1440 nsi svchost.exe                   1448 wudfsvc svchost.exe                   1528 hidserv svchost.exe                   1628 Dhcp svchost.exe                   1716 Dnscache svchost.exe                   1748 EventLog WUDFHost.exe                  1792 N/A svchost.exe                   1908 TimeBrokerSvc svchost.exe                   1952 NlaSvc NVDisplay.Container.exe       1968 NVDisplay.ContainerLocalSystem svchost.exe                   1324 Themes svchost.exe                   1596 ProfSvc svchost.exe                   1944 EventSystem svchost.exe                   1052 netprofm svchost.exe                   2116 StateRepository svchost.exe                   2256 SENS svchost.exe                   2296 AudioEndpointBuilder svchost.exe                   2304 FontCache (etc)...   I know you can configure individual services to run in their own instance of svc with the sc config &lt;serviceName&gt; type= own command, but to my knowledge I've never run this command.  I took a quick look at Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and it looks like the Type key values for most of these services is missing the flag bit at 0x10 which controls if a service runs in its own svchost.exe instance or not. I wonder what could have effected this change.  Has anyone else observed this behaviour before or after installing Windows 10 Creators Update? If it is a default configuration change, will it have any implications on system performance or stability?  I suspect it will increase system stability because if a service crashes it won't bring down other services - but this comes at a massive cost of RAM - but I've never experienced a service crashing on me - or at least ever noticed it (instead the worst problem I've had is with wuauserv consuming 100% CPU for hours on end - and that's not a problem process isolation will solve).  (I just noticed: they finally added an address bar to the Registry Editor!) Why do two bodies of different masses fall at the same rate (in the absence of air resistance)? Can one explain the different distributions of the Saxon and the analytic (Norman) (periphrastic, 'of') genitive I'm curious of how illusions would affect spells or abilities that require a target to be looking at something. A good example of this would be Medusa's Petrifying Gaze which has the following effect:  Petrifying Gaze: When a creature that can see the medusa's eyes starts its turn within 30 feet of the medusa, the medusa can force it to make a DC 14 Constitution saving throw if the medusa isn't incapacitated and can see the creature. If the saving throw fails by 5 or more, the creature is instantly petrified. [...]  So if someone were to cast Minor Illusion to put a bag over Medusa's head, would other player/creatures who do not realize that the bag is an illusion be affected by the gaze if they were looking in the direction of it? Does the illusion block the effect? I've not seen/read any female Orcs mentioned in the movies or in the books. In one of the movies, an Uruk-hai is momentarily shown emerging from a giant, grown-Orc sized flesh packet. So are they created with spells, or do they follow the Standard Reproductive Model. Is it possible to save settings for Microsoft Paint? After closing paint the last used settings went back to default. I want them to be saved. Like the selected Brush-Tool, Color, Line-strength, etc.  Either after every usage or I define one I use most. Maybe through the registry or by start parameters? Forgot which email I used, can't login I forgot what email I used for my other ploxtic id: how do you find out what my email was?   The account is user:2078229. Suppose the following dialogue:  ... &quot;I accept only one notion of land property. Namely, 'I am doing my stuff here, therefore I am here&quot;. &quot;But this means,&quot; he responded, &quot;you can break into any place and stay there, using this rule.&quot; &quot;There is another rule, though. Right to act in its most natural sense, 'I am here, therefore I am doing my stuff here.&quot; &quot;But do not these rules put together become circular reasoning?&quot; &quot;Of course, they do,&quot; I put my head closer to him, &quot;and this is exactly that rare case when circular reasoning is not only sufficient, but is necessary.&quot; &quot;But why is that? Circular reasoning never was a correct argument.&quot; &quot;There are many circular things happening in nature. Life forms, for example, exist only in order to produce new life forms or to prolongate their own lifetime. Is there any reason to say this can't be the case for reason itself? Why must reasoning not be circular?&quot; ...  Can circular reasoning ever be justified? For example, we know all the words in our languages can't be defined using other words without the use of circularity. We know logic can't prove itself without circularity. Are these arguments rational? Are there any other arguments where circular reasoning is still rational?

In C#, can I convert a string value to a string literal, the way I would see it in code? I would like to replace tabs, newlines, etc. with their escape sequences.

I don't know if this is possible on Adobe Reader DC on Windows, but asking in case someone has managed to do it.   When I am working on a large document in LaTeX (I use TexStudio) I sometimes like to keep a second copy of my PDF on a second screen so that I can easily refer to what I wrote before, while on my main screen I would have TexStudio with its preview window, which is typically automatically in sync with my current editing location.  On Ubuntu (which uses evince as its default PDF viewer) I used to do it quite nicely. It also seems to watch the PDF file for updates, and keeps in sync of any new versions of the PDF file and reloads it (staying on the same page) when I re-run pdflatex from TexStudio.  At the moment I am working on a Windows machine, and I am trying to recreate the same workflow. I would really like to open a second viewer on my second screen so that I can navigate easily to previous chapters without losing my current position in TexStudio's preview window (which will anyway go back to the current editing location when I run pdflatex).  The only problem however is that when I open the PDF in Adobe Reader DC to put it on the second screen and then I try to recompile the PDF I get the error "I can't write to file". I presume that for some stupid reason Adobe Reader DC maintains some write lock on the file, probably keeping it open while the PDF is visible on screen.  Is there a way to disable this stupid file-locking behaviour from Adobe Reader DC?  UPDATE  After some valuable comments, a workaround is possible using a different viewer. One could either use  or  (the default PDF viewer on Ubuntu, but also available for Windows). They are not so feature rich, and maybe do not look so nice, but in this case do the job.  A similar question was posted  for reference. Why can't I connect to Pokemon Go via mobile data? How can I assign a Func conditionally between lambdas using the conditional ternary operator?
