This is my first tex question. I couldn't find a duplicate since I'm not even sure how to describe this layout in English...It looks like this:  [item1]     [explanation of item1......may be very long             accross several lines, may contain math, and             need to be wrapped automatically]  [item2]     [explanation of item2.......................             ............................................             ....................]   The space between items and explanations should be adjustable (usually several tabs in vim).   I have tried the alltt package and use tabs(spaces) to get the layout, however, it cannot do automatic line wrapping and I have to manually break lines, so that's not really a solution.  Thanks in advance for any help.
Which is the right way to do something like 'description' list but with customizable and fixed-width labels? I.e. something like this:  Label:         Text text text text text text                text text text text. Longer label:  Text text text text text text                Text text text text.   The way I see it to use two-column table (first columt for labels and second column for descriptions), but this solution seems ugly. Is there any other way?
What does goodness of fit mean in context of linear regression I am having trouble understanding the concept of 'goodness of fit' w.r.t linear regression. The name suggests that the goodness of fit test is used to determine how well a model fits the data.  But the linear model is already the 'best' fit since we have minimized the sum of the squared error terms. Why do we need to test 'goodness of fit' again? We know it is a good fit because we minimized the sum of the squared errors. Alternative to Photoshop or Paint.NET I have been moving toward Ubuntu from a long time Windows development background. The one program I cannot seem to do without is a graphic editor. I have seen recommendations for programs, but they turn out to be directed at children or tailored to working with personal photographs.  I am looking for something more for programming tasks like analysing colors, resizing, creating web graphics, etc. I have used Photoshop in the past and more recently have mostly used Paint.net for Windows.  Is there a program for Ubuntu that covers this area? What award did Leia give Chewie, Han and Luke?

Enable SSO for Salesforce Marketing Cloud I need to enable Single Sign On for Salesforce Marketing Cloud account where Identity Provider will be a third party and Marketing Cloud will be the Service Provider.

If anyone of you guys has done SSO enabling for Marketing Cloud, please share steps. How to use Stokes theorem in the presence of holes? Is the oil thrown on a creature consumed when it's dealt fire damage and lit? I had the idea of throwing oil flasks on enemies at level 1, then hitting them with a torch to deal a bunch of bonus fire damage.  PHB 152:     If the target takes any fire damage before the oil dries (after 1 minute), the target takes an additional 5 fire damage from the burning oil.   PHB 152:     If you make a melee attack with a burning torch and hit, it deals 1 fire damage.   A flat 6 fire damage is pretty potent at level 1, but does the oil remain or does it burn out in a flash when hit (since it has no damage over time) when hit?  If not there is potential for a dual torch wielding PC to throw down 12 fire damage per round, or for multiple PCs to deal 6 damage per torch per PC per round. In Drupal 8 you can load an entity with:  $node = \Drupal::entityManager()-&gt;getStorage('node')-&gt;load(123);   This looks for the entity definitions and finds that node is defined by Drupal\node\Entity\Node - so (I guess) Drupal\node\NodeStorage will instantiate a new Drupal\node\Entity\Node instance.  What I'd like to achieve is subclassing Drupal\node\Entity\Node and being able to instantiate this subclass when it's appropriate. For example if I have a node bundle article, there would be a class:  namespace Drupal\my_module\Entity\Article; class Article extends Drupal\node\Entity\Node { }   And I'd call:  $node = \Drupal::entityManager()-&gt;getStorage('node_article')-&gt;load(123);   And the return would be my Article subclass.  I can achieve this by creating a new entity type and wiring it back to another existing entity definitions, for example the node-article example would be this class:  namespace Drupal\my_module\Entity; use Drupal\node\Entity\Node; /**  * @ContentEntityType(  *   id = "node_article",  *   label = @Translation("Content"),  *   bundle_label = @Translation("Content type"),  *   handlers = {  *     "storage" = "Drupal\node\NodeStorage",  *     "storage_schema" = "Drupal\node\NodeStorageSchema",  *     "view_builder" = "Drupal\node\NodeViewBuilder",  *     "access" = "Drupal\node\NodeAccessControlHandler",  *     "views_data" = "Drupal\node\NodeViewsData",  *     "form" = {  *       "default" = "Drupal\node\NodeForm",  *       "delete" = "Drupal\node\Form\NodeDeleteForm",  *       "edit" = "Drupal\node\NodeForm"  *     },  *     "route_provider" = {  *       "html" = "Drupal\node\Entity\NodeRouteProvider",  *     },  *     "list_builder" = "Drupal\node\NodeListBuilder",  *     "translation" = "Drupal\node\NodeTranslationHandler"  *   },  *   base_table = "node",  *   data_table = "node_field_data",  *   revision_table = "node_revision",  *   revision_data_table = "node_field_revision",  *   translatable = TRUE,  *   list_cache_contexts = { "user.node_grants:view" },  *   entity_keys = {  *     "id" = "nid",  *     "revision" = "vid",  *     "bundle" = "type",  *     "label" = "title",  *     "langcode" = "langcode",  *     "uuid" = "uuid",  *     "status" = "status",  *     "uid" = "uid",  *   },  *   bundle_entity_type = "node_type",  *   field_ui_base_route = "entity.node_type.edit_form",  *   common_reference_target = TRUE,  *   permission_granularity = "bundle",  *   links = {  *     "canonical" = "/node/{node}",  *     "delete-form" = "/node/{node}/delete",  *     "edit-form" = "/node/{node}/edit",  *     "version-history" = "/node/{node}/revisions",  *     "revision" = "/node/{node}/revisions/{node_revision}/view",  *   }  * )  */ class Article extends Node { }  // Results my Article sub type. $node = \Drupal::entityManager()-&gt;getStorage('node_article')-&gt;load(123);   This works fine (as much as I can see); however, it smells. It adds a new entity type, which is not true, and might cause other troubles in the future.  How do I define a subclass for an entity bundle so that loading the entity would return an object of that class? I recall Asimov had a character who was The autoc of , clearly based on the word “autokrat” but I don’t recall the exact spelling.  This stumped Google, which would rather correct the spelling to some other word than find a unique word.  In the story, he had gone undercover and the reader did not know either that some other character was in fact the Autoc, until it had been revealed to the main character. Jamaica Inn episode 5 from BBC learning English drama section:  The dialogue says:     Mary: My aunt is in bed.   She doesn't say -      My aunt is in the bed.

Partial Sums of Geometric Series Deriving Sum of a Geometric Progression Tempdb Add files require Restart Does adding Tempdb files require a restart? We would like to Add files on the same drive, Not Delete and Not modify. We tested in Dev and QA environment, restart was not required. However for production I would like to be sure everything works properly. Some are stating conditions, not always necessary, sometimes necessary, I am reading resources below:  ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev2', FILENAME = N'G:\tempdb2.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0 ) GO ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev3', FILENAME = N'G:\tempdb3.ndf' , SIZE = 12288000KB , MAXSIZE = UNLIMITED, FILEGROWTH = 0    Do You Need an Outage to Add tempdb files? Brent Ozar  "Technically, not always. But practically speaking, yes. If you have to shrink files, that’s very difficult while SQL Server is in use, and we’ve seen cases where anti-virus/file control tools didn’t act up until SQL Server was restarted after the files were added."   "Once the additional files have been created, it’s not always necessary to perform a service restart.  However, in many production environments, simply modifying the filesize of the existing TempDB datafile (tempdev) is not possible without restarting services first. "  The following resources are saying no restart required: How can I reset or revert a file to a specific revision? I have made some changes to a file which has been committed a few times as part of a group of files, but now want to reset/revert the changes on it back to a previous version.   I have done a git log along with a git diff to find the revision I need, but just have no idea how to get the file back to its former state in the past. Can we opt for fast track service after the refusal? Last Saturday, I got a refusal from BHC due to lack of funds and my reasons to come back to India. I am planning to visit my family who are settled in the UK. I am married and planning to visit my family along with my husband. My father is sponsoring our whole trip. But we got a refusal as we didn't show much funds in our account. We thought that if my father is sponsoring, we should show his documents only. But now I have applied again with a fast track service. Will BHC will consider it under the fast track process? This time I have cleared all their doubts which they mentioned in the refusal letter. How to delete a file with a weird name? I wrote a program that uses POSIX memory-mapping function (mmap)  The program takes a file (a.dat) and memory-maps it for reading/writing.  Due to errors in the program, every time I run the program a file with some weird names (e.g., ?d?P?^z??d?P?^z?) is created. The error is resolved but I am not able to delete the files.  I am not able to delete it either using command line or by select/deleting from window manager.  So how should I delete it? I'm using Ubuntu 11.04. How to turn off Facebook notifications on Mac OS X?

Installing Ubuntu 13.04 on a MSATA SSD I am trying to install Ubuntu 13.04 on my 24Gb MSATA SSD. In my laptop, I've also got a 500Gb SATA HDD. I realize that in order for this to work I need to put my /home directory on the 500Gb HDD.   I've tried installing it by creating a ext4 partition on the SSD and a 8Gb swap partition on my HDD. This resulted in an error saying something similar to Cannot install bootloader, please select an other location for the bootloader.   Now before I waste any more time trying to get it to work I'm going to ask a bunch of questions:   Where should I put the swap partition? How big should I make the swap partition? (I've got 12Gb RAM) My 500Gb HDD is currently in Raid mode. Should I change that (to AHCI or IDE)? Where should I put the bootloader if the error message occurs again? How do I make the home directory point to the HDD instead of the SSD? Can I configure Ubuntu to install software/packages on the HDD instead of the SSD? After installing fedora and Centos and other OS now I have them all showing in my Boot menu [F2] on start up not the menu form the OS even after deleting them and reinstaling other OS - Ubuntu -so It just shows one when the OS starts but when I go to UEFI setting I still find all the old ones they instruct you to use DEL to take them out but that does not work
