Latest NVIDIA driver on Ubuntu 16.04 How much money did Charlie Harper have? This is quite tricky to figure out, and I am not looking for a specific number, but for a approximation.  As you know, Charlie (nearly) always had a lot of money to spend, but a few hints suggest that he actually did not have money at all (talking about absolute, not cash flow)   he went bancrupt after a few months without income he told Alan that there is no money, and everything just a house of cards he worries about Bertha giving away a few clothes he has three mortgages on his house when he died, there was no inheritage to Alan or anyone, and they had to sell the house ...   However, considering the lifestyle and spendings, Charlie must have had a substantial amount available.   driving the latest foreign expensive cars owning a malibu beachhouse paying the property tax for said house discussing retirement at 45 spending endless money on booze, betting and women ...   So all things considered, did he have money, or was he just a scam? Can the problem of unification of Quantum Mechanics and General Relativity be converted into a pure Mathematical problem? I mean to say, can you make someone understand the problem who only knows Mathematics, even if a Physics description is absent? I mean, describing the problem with unification using pure Mathematical formulation.  Can we make the problem seem as if it has nothing to do with the real world and describe it only as a problem of mathematics? This user is only displaying 56 rep.

I have a built a Wordpress site that enables comments on pages and I am using them as reviews, what I would like to do is for someone to be able to make a comment on a page without being on that page.    On the link above, the top right, there is a link that says have your say about a university, it would be good to have a HTML form and then a dropdown box of all the child pages of university-guide; which is where all the universities are stored, and then I can put my comments.php file into this.  So my HTML form appears and when a page is picked from a dropdown box, the comment will then be assigned to that page.  Any help or direction?    New Question for Toscho:  Below is your tweaked plugin to fit into my website, as you can see I have added the select option yearSelect and need this to appear when the comments appear.

Am I doing it in the right way? I've never worked with Linux before and tried to search for it but found no solutions. The various modern revolutions in physics, in psychology, in politics, even in literary style, have not escaped his intelligent notice, but they can scarcely be said to have influenced him deeply.    Could you please explain the following?  They can scarcely be said to have influenced him deeply.  Or, I can not understand such a structure like the following:  In contrast, prices set by a central planner are necessarily arbitrary, since there is no standard against which they can be said to be correct or incorrect. d'oh! Aliased edge around light source in cycles Often when a mesh light is visible in the camera, the edges are not anti-aliased.  No matter how many samples I do, the lamp border always looks jagged and pixelated.  Is this a rendering error? How can I get around this issue?    And zoomed in 4x: How to add Lat/long columns to a point layer which is not in WGS84? I need to extract the Lat/long coordinates of the centroids of districts. My QGIS project SCR and the different layers have all been set on "WGS 84 / UTM zone 18N".   I've created the centroids using the usual tool. I could then extracted the coordinates using the "Vector > Geometry Tools > Export/Add Geometry Columns", or saving the layer in CSV typing "GEOMETRY=AS_XY" in the "Layers" part of the "OGR creation options".  Nevertheless, both methods output Cartesian coordinates, whereas I need Lat/long coordinates. Let $A$ be a UFD. Assume that $a,b \in A$ are relatively prime, $c \in A$ and $a | bc$. To prove that $a|c$, is the following approach correct (or do you have to use some type of prime factorization argument)?  By the relatively prime assumption, $\gcd(a,b)$ is a unit. Call that unit $u \in A^{\times}$. Then we can write $u = ax + by$ for some $x,y \in A$. But then, $c = c \cdot u = c(ax+by)=cax+cby$. However, it is clear that $a|cax$ and the fact that $a|bc$ implies $a|cby$. Thus, $a|cax+cby=c$. Proof problem: Show that $n^2-1$ is divisible by $8$, if $n$ is an odd positive integer. Why is it wrong to serial voteup someone you like his answers?  Sometimes I just came to stackoverflow to read certain people answers(there are 4 guys currently) I have their profile bookmarked in my browser and in my free time at office I go to their profile and read their answers and learn a lot from them, but because I'm afraid to be a serial voter, I dont voteup them.   I think there is nothing wrong with that, if there is, please let me know. I know that this question is a bit old or maybe overdone, but I'm running the latest edition of Blender and when I use the Cycles engine I get really fuzzy results and I can't find a simple, non-compromising solution to the quality.  I don't know exactly what I'm doing wrong here, but I'm sure others share my frustration.  Leaving everything in default settings, I started a new project and switched to the Cycles render.  I duplicated the cube and set colors for two Diffuse BSDF shaders, then went ahead and made walls and a floor all sharing the same diffuse shader.  I made two windows to emit blue light.  The screenshot has gaps between the walls because of the setup:  I'm aware that it's considered very incomplete and many have come to terms with some amount of noise, but is this normal?  Furthermore, with default settings or not, I can't change the amount of noise produced.  Supposedly, using "progressively refine" in the rendering tab should make it refine itself indefinitely, however Cycles only counts to 10 refines and then stops, creating a render which is a pixel-perfect match of the ordinary rendering method when it's completed.  I understand that there are tricks that can be used to reduce noise, but at the cost of extra processing time and usually small quality conflicts, like blurring.  My question essentially boils down to is this Cycles' current limit? Cutting a circular hole in a hollow cylinder without distorting the cylinder Whenever I try to cut out a circular hole in either a cylinder or sphere the polygons around the circular hole always have distorted normals after smoothing. Is there anyway to fix this. I've tried using the remesh modifier but wind up with some pretty ugly results. How to catch and print the full exception traceback without halting/exiting the program? Why are these black dots / spots appearing in my pictures? How can I modify the advanced search form when my hook runs too early? I'm using  to modify the content of the form on the search page &mdash; I want to remove the "phrase" and "not" fields, and restrict the "only of the types" checkboxes to a hand selected list of types.  I have the following code, which is being called and which I think should work:  function MYMODULE_form_search_form_alter(&amp;$form, &amp;$form_state, $form_id) {     unset($form['basic']);     unset($form['advanced']['keywords']['phrase']);     unset($form['advanced']['keywords']['negative']);     unset($form['advanced']['type']);     $form['advanced']['type'] = array(         '#type' =&gt; 'checkboxes',         '#title' =&gt; t('Only of the type(s)'),         '#options' =&gt; array(             'blog' =&gt; 'Blog entry',             'event' =&gt; 'Event',             'news' =&gt; 'News article'         )     );     // print_r($form);     // die; }   Except  gets to the search form after my form alter hook runs, so I don't get a chance to modify any of the form elements that it's adding.  I'm running Drupal 7.22.  How can I modify the advanced search form when my module hook runs before the hook that defines the advanced search form? Move data from regular partition to lvm I've read a bit about lvm and decided that I want to switch to using it. It seems like actually setting up lvm can be done from the debian installer, so I suppose that'll be easiest. What I'm not sure about is how to copy all of my files to the new system.   I would like to copy my whole system, not just my home directory or just my packages, I've messed around with a lot of stuff, to the point where I have no idea exactly where all of my config files live. The guides I've found on the internet seem to glaze over this step, just mentioning tools that can do it, not how to use them, i.e. use rsync. Instinct tells me I can't just rsync the root of my backup to the root of my lvm system, I'll copy over something important, like the lvm config files, but I'm not sure what exactly I need to exclude, while being sure not to exclude anything I might have changed. Any tips?  My planned steps, for clarity: I have a 1tb hdd and a 250gb ssd. I want to shrink the partition I have on the hdd, use the free space (I have enough) to make two new partitions, and dd my ssd and hdd partitions to those partitions as a backup. Then I want to wipe the ssd partition and hdd partition I'm currently using, and set up lvm on them (ideally with the debian installer for simplicity's sake, but maybe manually). And then I want to copy everything from the backup partitions to the new lvm partitions, somehow. And then wipe the backup partitions and either resize the existing lvm partitions to include the remaining space, or just make the remaining space another physical volume on lvm and add it that way. Can you end Beast Form early? Is there any way to end beast form early? I find myself using it to clear out a particularly hard portion of a dungeon at times, but then I have to sit around for 2-5 minutes so I can be my human character again (I have to feed to keep my health up, so I'm a werewolf longer than the 2.5 minutes).  Is there anyway to end it early? Ubuntu 18.10 Cosmic not starting GNOME session on bootup
