I upgraded today from Sierra to Mojave and now my share menu seems to be broken.  Previously I could share content directly to sites like Facebook and Twitter. For instance I could right-click on a photo and choose to share it to Twitter, Facebook and so on like so:    Now if I click on a photo and choose to share, I don’t get Twitter or Facebook as options anymore:    How can I enable these options?
Why is Facebook missing from the list of ways to share a page in Safari?  That option used to exist before the latest update.  When I'm directed to the extensions box Facebook is not there.
Isomorphism equivalence implies fundamental group is abelian How to find fixed points for DES weak keys What is a loss function in decision theory? My notes define a loss function as the 'cost' incurred when the true value of $\theta$ is estimated by $\hat\theta$. What kind of cost is it talking about? monetary cost? or is it something related to errors? I'm running tests of a variable-size-and-contents test set. Data files are added and removed frequently. I'm looking for an automated way of gathering a file list.  All files are in subdirectories of D; I need the full directory and name added to a text file. However, I only need those files that have a "paired" file, which has the same filename but a different extension (so... different filename, but in a structured way). So, if there is a MyFileName.A and MyFileName.B, then I want D/.../MyFileName added to the file list.  There are .A files without .B files, but no .B files without .A files. If a .A has a .B file, then both files are in the same directory.   Any advice? Accepting an answer should automatically upvote it as well Is there ever a case where you would want to accept an answer, but not upvote it?  I can't think of a single situation where this would be the case.. So would it not make sense to have the "Accept" button upvote the answer too? A correct preposition - account closed due/by/at 12th of May I asked my bank to close my account on 12th of May. Also     I expect the account to be closed [?] 12th of May   . What preposition should be there? I think about by or due. Also if I want to ask someone a question: What date was your account closed [missing preposition?] I'm new to latex, I'm thankful if someone can give me an example script to customize TOC that looks like  Chapter 1.XXXXXX                                                            (1-15)  1.1 Introduction 1.2 xxxxxxxx 1.3 xxxxxxxxxx 1.4 xxxxxxx ...............

(16-30)  because the (default) TOC appears to be very large for my book, since it arranges the section name row-by-row. Is the uncertainty principle a property of elementary particles or a result of our measurement tools? In many physics divulgation books I've read, this seems to be a commonly accepted point of view (I'm making this quote up, as I don't remember the exact words, but this should give you an idea):      is not a result of our lack of proper measurement tools. The fact that we can't precisely know both the position and momentum of an elementary particle is, indeed, a property of the particle itself. It is an intrinsic property of the Universe we live in.   Then this video came out:  (skip to , if you're already familiar with the uncertainty principle).  So, correct me if I'm wrong, what we may claim according to the video is:     the only way to measure an elementary particle is to make it interact with another elementary particle: it is therefore incorrect to say that an elementary particle doesn't have a well defined momentum/position before we make our measurement. We cannot access this data (momentum/position) without changing it, therefore it is correct to say that our ignorance about this data is not an intrinsic property of the Universe (but, rather, an important limit of how we can measure it).   Please tell me how can both of the highlighted paragraphs be true or how they should be corrected. Can we insert or update FieldSets using apex code?

What governor limits impact Apex Describe methods? Are there any governor limits, or considerations that I should be aware of when using Apex Describe methods?  So for example, the author of this blog post uses the structure below to get the record type instead of doing a soql query.     //Generate a map of tokens for the sObjects in your organization Map gd = Schema.getGlobalDescribe();  //Retrieve the describe result for the desired object DescribeSObjectResult result = gd.get('Account').getDescribe();  //Generate a map of tokens for all the Record Types for the desired object Map recordTypeInfo = result.getRecordTypeInfosByName(); system.debug('RECORD TYPES:' + recordTypeInfo);  //Retrieve the record type id by name String recordTypeId = recordTypeInfo.get('RECORDTYPE_NAME').getRecordTypeId(); Adjusting space between array rows and columns \documentclass[english]{article} \usepackage[T1]{fontenc} \usepackage[latin9]{inputenc} \usepackage{babel} \begin{document} % ... \[ \begin{array}{ccccc} x(1) &amp; = &amp; \frac{x(0)}{1} &amp; = &amp; x(0)\\ x(2) &amp; = &amp; \frac{x(1)}{2} &amp; = &amp; \frac{x(0)}{2}\\ x(3) &amp; = &amp; \frac{x(2)}{3} &amp; = &amp; \frac{x(0)}{2.3}\\ x(4) &amp; = &amp; \frac{x(3)}{4} &amp; = &amp; \frac{x(0)}{4!}\\  &amp;  &amp;  &amp;  &amp; \vdots\\ x(n) &amp; = &amp; \frac{x(n-1)}{n} &amp; = &amp; \frac{x(0)}{n!} \end{array} \] % ... \end{document}   Because of the fractions in the array cells, array elements are vertically too close to each other, they are literally touching to each other.

Materials for learning TikZ How to disable Import option in LibreOffice Calc while pasting text in a cell? I'm making a table in which I have to copy few lines from pdf to a table. I'm using LibreOffice calc for table making purpose. Problem is that even though I am copying simple text from the pdf, when I paste it to LibreOffice, Import Option keeps on poping up(randomly-sometimes it pop up sometime it does't). And due to this pasted text's font size also very small. Desired result is that when I paste the text in the cell, it just got pasted in the cell, without any time wasting popup which also disturbs the font size. Same question is asked here but no solution. Why does my computer get less battery life with Ubuntu compared to Windows? Last year I purchased a Dell Inspiron 5315 laptop shipping with Windows 7 preinstalled. I installed Ubuntu 10.10 alongside it with dual-booting. On upgrading to Ubuntu 11.10, I was upset to find I now get less than one hour of battery life! Windows 7 gives me 2.5 hours of running time.  Is there any possible explanation why  my battery is running out faster with Ubuntu? Can anybody tell me better power options?
