My document is in (AMS article) mode. The title of my paper shows up as a header on each page. The problem is that the title is too long and it overlaps with the page number. I would like to use a different (shorter) header (one header for all the pages except the title page) or erase the header on each page altogether. How would I do either of these?    If the source code or preamble needs to be edited, can you explain how I can go about making the edit in LyX? (I.e., do I use ERT, edit the settings or something else?)  Here's the source code for the title, but I am not sure if it's helpful:   \title{{\small{EST}}}   \maketitle   My preamble is empty.  Edit: How can I make any of the suggested edits in the linked question in LyX?

Ubuntu stuck/freeze on install I've been trying to replace my current Windows 10 installation with Ubuntu 16.04. My computer is a Lenovo Thinkpad T470. I've formatted my 15GB USB-dongle. Downloaded the software Rufus, and burned the ISO onto the USB. I've tried the settings "MBR Partition for BIOS or UEFI", "MBR Partition for UEFI" and "GPT partition for UEFI". I've tried using memtest86+ to test if I have any memory errors, I have not. I've tried disabling Secure boot, and Fast startup. I've tried using other software than Rufus, and I've tried entering the "nomodeset" in the boot options, as well "acpi=off", nothing works.   When I boot from my USB. I choose "Install Ubuntu" from the grub menu. And then select my language in the installer. It is from this point on, it gets problematic. Sometimes when I try to connect to my WIFI, it connects successfully, but when I press the "continue" button, the installer freezes and nothing happens. Sometimes I get past this point, but it then freezes later on in the installation progress - typically right when I press the "Install now" button.   It should also be mentioned that, if I press the "Quit" button in the install. I get to a black screen with a lot of text saying something like squashfs error.   Can someone please help me? When I tried booting memtest86+ it only worked when I changed my boot mode from UEFI to Legacy. Could this be it? Are there any downsides to installing an operating system in legacy?   If anyone has any other suggestions, it would be greatly appreciated!  Thank you :-) How to create a filter in Gmail to identify messages forwarded from Zimbra?

Subdivision surface modifier creates pinching at corners I've only been 3D modelling for a few days now, so this may just be a newbie mistake:  However, because this model is for use in a game I am trying to stay away from proximity loops for performance reasons. Instead, I have used edge creases to maintain the structure of the model. It has led to certain vertices not being affected by the subsurf modifier, causing undesirable lighting at high subsurf levels.  Manually moving each point in a bit seems kind of sloppy but I'm not too sure what the best way to go about this is.  If any more information is needed I'll give what I can, thanks in advance :) Oven Temperature: How to be sure the selected temperature is correct. I suspect that my - fairly new - oven gets too hot, so I bought an oven thermometer, which confirmed this.  So I called the supplier.  They say that in order to obtain the correct actual  oven temperature, for any setting, you take the highest reading on the thermometer, and the lowest, and then divide both readings.   Is this correct? Why don't the White Walkers take the sea route to Westeros Calculate $E(Y)$ and $Var(Y)$ given the random variable which is exponentially distributed The random variable $X$ is exponentially distributed with parameter $\lambda = \dfrac{1}{2}$. Also, define $Y = -2X + 1$. Calculate $E(Y)$ and $Var(Y)$.  So we have   $$f_X(x) = \dfrac{1}{2} e^{-\dfrac{1}{2}x} $$  if $x\ge0$ and $0$ otherwise.  But how to calculate $E(Y)$ and $Var(Y)$ ?

I shared a compartment with another American backpacker (and others.) The border crossing on the Romanian side was normal -- all of our passports were stamped and the border officer recorded our data in his notepad. On the Hungarian side, some sort of commotion broke out further down the train car while we were being processed. The officer who was scanning and stamping our passports left and never came back. As a result, the other American backpacker never had her passport scanned or stamped.  What sort of difficulties might she run into since her passport has not been recorded as entering the schengen zone, nor does she have an extra stamp? What might get options be now, from within Schengen, to get her entrance recorded?  (When I say "scanned", the officers had hand-held devices that read the passport biometrics and I assume, recorded some sort of data somewhere.) $\forall a,b,c \in \mathbb{N}\!:\ a\mid b \Rightarrow ac\mid bc. $ Divisibility Proof Could someone verify this proof?  Given the following definition of divisibility $(\forall{a,b \in \mathbb{N}})[a \mid b \equiv (\exists{c \in \mathbb{N}})(ac=b)]$.  Statement: $(\forall{a,b,c \in \mathbb{N}})[(a\mid b) \rightarrow (ac\mid bc)] $ .  Proof:  Let $a,b \in \mathbb{N}$ be arbitrary.  Assuming that $a\mid b$, we can conclude that $\exists{d \in \mathbb{N}}$ such that $ad = b$.  By Algebra we can deduce the following sequence of statements.  If $(ad)=b$, then $(ad)c=bc$.  Therefore $(ac)d=bc$.  Hence by the definition of divisibility we know that $ac\mid bc$. Can anyone help me out with how to make Bing Picture to my Desktop Wallpaper?

Thank You in Advance :) Sci-fi book where humanity is rebuilt on a new planet after being wiped out The closest I can get to making mesh lights affect their environment in Blender Eevee is giving them an Emission material and turning on "Bloom". But this isn't emitting proper light, it just looks like it is, but it doesn't light the surroundings whatsoever.     I would like to be able to light a scene with meshes without having to put point lamps everywhere just to make them emit light. Ideally, I'd like to write a unit test to help me "dummy check" for unexpected effects of the upcoming guest user sharing setting changes.  We'd had some controller/trigger code "gracefully handling" data it couldn't see thanks to the new sharing restrictions ... which resulted in simply "not doing" some work that it was supposed to do, which from a business process perspective isn't "graceful" at all (it was an important automation for downstream processes).  I'd like to write up a unit test with some system.assert statements validating that "data still goes where it's supposed to" when the "submit" button a public-facing Visualforce page of a community is clicked.  Unfortunately, I can't seem to make the "submit" button on a Controller for a public-facing Visualforce page work in the context of a unit test because the record whose creation it results in doesn't get its corresponding "sharing setting" record created in time for the execution context to pick it up.  I did a little proof of concept here ...  @isTest public class TestClass {      private static Id guestProfileId = Util.getProfileIdByName('Public Facing Portal Profile');     private static User guestUser;     private static Id portalGroupId = [SELECT Id FROM Group WHERE Name = 'Public_Portal' LIMIT 1][0].Id;      private static Custom_Object__c co;       private static testMethod void runTest() {         createCO();         Test.startTest();         // Note that putting createCO() inside the test and doesGuestSharingRuleExistForCO() doesn't help.         // That's what I was afraid of.         try {             doesGuestSharingRuleExistForCO(co.Id);         }         catch (Util.DeveloperException e) {             System.assert(FALSE, e.getMessage());         }         Test.stopTest();     }       private static void cacheUsers() {         guestUser = [SELECT Id FROM User WHERE profileid = :guestProfileId AND IsActive = TRUE LIMIT 1][0];     }      private static void createCO() {         co = new Custom_Object__c();         INSERT co;     }      private static void doesGuestSharingRuleExistForCO(Id coId) {         List&lt;SObject&gt; existingSharingRulesOnCO = [             SELECT Id FROM Custom_Object__share             WHERE RowCause = 'GuestRule' AND AccessLevel = 'Read' AND ParentId = :coId AND UserOrGroupId = :portalGroupId LIMIT 1         ];         if ( existingSharingRulesOnCO.isEmpty() ) { throw new Util.DeveloperException('Guest User sharing is not on for this custom object ID'); }     }      private static Boolean isCOSharingFlippedOnAtAll(){         String lookingFor = 'Custom_Object__Share';         for (Schema.SObjectType sObjectType : Schema.getGlobalDescribe().values() ) {             String sobjName = String.valueOf(sObjectType);             if (sobjName.contains(lookingFor) ) { return TRUE; }         }         return FALSE;     }  }   Am I just out of luck?  Is there no way to properly unit-test the effects (to automations relying upon "guest user" sharing settings when running as "guest user") of simulating the insertion of records into my database from a Visualforce page, due to not being able to separate out "execution context" enough and "wait" for the sharing rule record for the new record to come into existence? heredoc for Windows batch?
