I follow all instructions in , and never see the chance to go to 18.04.2.  The command:  ubuntu-report show    "Install": {   "Media": "Ubuntu 18.04.1 LTS \"Bionic Beaver\" - Release amd64 (20180725)",     The update manager told me about 18.10 because I had changed the option to all updates instead of only LTS.  When I have it set to LTS, it shows nothing is available to update.      31: cat /etc/lsb-release     DISTRIB_ID=Ubuntu     DISTRIB_RELEASE=18.04     DISTRIB_CODENAME=bionic     DISTRIB_DESCRIPTION="Ubuntu 18.04.2 LTS"   As you can see, I do have 18.04.2.  I just can't figure out in the StackExchange UI how to say my problem is solved.  If someone could mark it as such, I'd appreciate it.
There are so called "point releases" for LTS versions of Ubuntu. 10.04.3 for instance.  What are those "point releases" releases?
Why can templates only be implemented in the header file? Quote from :     The only portable way of using templates at the moment is to implement them in header files by using inline functions.   Why is this?  (Clarification: header files are not the only portable solution. But they are the most convenient portable solution.) How can I remap a keyboard key?

A program I am using spits out LaTeX tables in LaTeX files (outreg2 command from Stata), which I run using texify to make pdfs of the tables.  I crop these tables (using pdfcrop) and embed them elsewhere.  However, the pdfs include page numbers, which prevent pdfcrop from cropping directly around the table.  I need an automatic way to remove the page numbers before cropping.  I want to insert the command \pagenumbers{gobble} into the LaTeX code to automatically remove the page numbers.    I believe   texify --pdf --texinfo="\pagenumbering{gobble}" filename.tex   should work.  It does not. No exception pops up, but the page number remains. I cannot find documentation anywhere showing examples of using the --texinfo option to splice LaTeX code into the file before running the LaTeX file to create a pdf.   How should I properly use the texify command?  Or is there another way to splice in  \pagenumbering{gobble} before running texify? Django Template Variables and Javascript When I render a page using the Django template renderer, I can pass in a dictionary variable containing various values to manipulate them in the page using {{ myVar }}.  Is there a way to access the same variable in Javascript (perhaps using the DOM, I don't know how Django makes the variables accessible)? I want to be able to lookup details using an AJAX lookup based on the values contained in the variables passed in. How to make Latexmk use makeglossaries? Can I declare a duplicate page via javascript for google? Most sources of documentation state that one can declare a webpage a duplicate of another by applying this tag on the duplicate page:  &lt;link rel="canonical" href="(absolute URL to original page)"&gt;   I could generate the above tag via the script below:  &lt;script&gt; var l=document.createElement('Link'); l.rel='canonical';l.href='(absolute URL to original page)'; document.getElementsByTagName('head')[0].appendChild(l); &lt;/script&gt;   My question is, would google be able to process this javascript and believe I'm declaring the page as a duplicate page? or would I be forced to use the link tag in the header?  I ask because I'm trying to reduce the unnecessary bytes required to be processed before the actual user readable content begins. Photons have no mass but they can push things, as evidenced by .   Can photons push the source which is emitting them? If yes, will a more intense flashlight accelerate me more? Does the wavelength of the light matter? Is this practical for space propulsion? Doesn't it defy the law of momentum conservation?  Note: As John Rennie mentioned, all in all the wavelength doesn't matter, but for a more accurate answer regarding that, see the comments in  .

White's test for heteroskedasticity in R I am trying to estimate heteroskedasticity in R. I had Eviews available in my college's lab but not at home. I have been trying to use "het.test" package and whites.htest but the value that I get is different from what I get in Eviews. According to the author of the package, it is meant to do the same test as is done in Eviews.   My model looks like A~B+C. Kindly guide me what I am doing wrong.   I 1st run ols for equation A~B+C, after getting results, I clicked View&gt;Residual diagnostics&gt;Heteroscadicity tests&gt;White's (with Include white cross terms) and then Press ok. The result i got was Prob. F(5,27) = 0.2948.   For R, i tried code at this link [this link][1], here is the edited code that i used.  library(vars)  library(het.test) dataset &lt;- data.frame(A,B,C))  model1 &lt;- VAR(dataset, p = 1)  whites.htest(model1)   This gave me value of 0.63.

Loop "Forgets" to Remove Some Items You can use a standard dot notation or a method call in Objective-C to access a property of an object in Objective-C.  myObject.property = YES;   or  [myObject setProperty:YES];   Is there a difference in performance (in terms of accessing the property)? Is it just a matter of preference in terms of coding style? When I sum up the sizes of my files, I get one figure. If I run du, I get another figure. If I run du on all the files on my partition, it doesn't match what df claims is used. Why are there so many different figures for the total size of my files? Can't computers add?  Speaking of adding: when I add the “Used” and “Available” columns of df, I don't get the total figure. And that total figure is smaller than the size of my partition. And if I add up my partition sizes I don't get my disk size! What gives? How can I cast int to enum? How can an int be cast to an enum in C#? Real life uses of Moment generating functions In most basic probability theory courses your told moment generating functions (m.g.f) are useful for calculating the moments of a random variable. In particular the expectation and variance. Now in most courses the examples they provide for expectation and variance can be solved analytically using the definitions.   Are there any real life examples of distributions where finding the expectation and variance is hard to do analytically and so the use of m.g.f's was needed? I'm asking because I feel like I don't get to see exactly why they are important in the basic courses. How can I change the date and time on Ubuntu? Using dconf-editor I tried enabling   org -&gt; gnome -&gt; nautilus -&gt; list-view -&gt; use-tree-view     but even after the check box is selected, plus a reboot, it still doesn't switch to the tree view on the side bar.
