I have a content type that anonymous user can submit content, Now in a mobile application I want to let them submit content with REST API,   My snippet to submit :   (function($){                      jQuery.ajax({                         url: '/rest/session/token',                         method: 'GET',                         success: function (token, status, xhr) {                             var postData = {}                             postData.title = [{'value': 'My Basic Page'}];                             postData.field_enroll_email = [{'value': 'yusef@gmail.com'}];                             postData.type = 'enroll';                             jQuery.ajax({                                 url: "/entity/node",                                 method: "POST",                                 data: JSON.stringify(postData),                                 headers: {"Accept": "application/json", "X-CSRF-Token": token, "Content-Type": "application/json"},                                 success: function (data, status, xhr) {                                     console.log(data);                                 }                             });                         }                     }); })(jQuery);   this work correctly in browser console when I'm logged in, and When I try it without login return "403 permission is denied". I set permission for anonymous user to create "mycontent1" content. **I want to know how can   anonymous user post content with REST in Drupal? **
The Drupal 8 REST UI configuration page asks me to select Authentication providers for GET method; otherwise, it doesn't allow me to export the REST request.  How can I provide anonymous user to access my REST GET API without providing any auth information?
Easier/better way to compute and store a value that's accessed as a property? Problem after update: blue screen with only the mouse cursor Require reputation earned on the main site to vote on a per-site meta Upvoting requires 15 reputation, but the association bonus is taken into account, so if you have at least 200 reputation on any site, you can upvote on all sites in the network.  This is a bit problematic when it comes to per-site metas. The votes there are used to gauge the opinion of the community, and they are often taken into account when implementing new policies.  What can happen is that a post from a per-site meta is linked in an unrelated high-traffic chat room, usually because there is some entertaining drama going on or because someone posted a particularly bad idea. This can lead to an influx of votes from external users that usually wouldn't visit or use the site, but currently still can vote on their meta due to the association bonus.  I think a very low minimum participation on the site should be required to vote on meta issues. This would make the votes on the per-site meta more robust and less easily skewed by being linked from outside.  Not counting the association bonus for the upvote privilege would be enough, then all users would have to earn 14 reputation on the site itself. A book suggests that we should not interchange "so" and "so that". "So" means "therefore", and "so that" means "in order that". However, it seems to me that in many cases they don't actually have a difference. For example:     Alice got up at 5:00 A.M., so that she could drive her son to school.   If I substitute "so that" with "so", this sentence presents the exact same causal relation to me:     Alice got up at 5:00 A.M., so she could drive her son to school.   I must have missed something here, since English is my second language. Could somebody explain the difference? Are nuclear weapons simply non-existent in the Star Wars universe? The resistance is attacks the Starkiller Base with what appears to be pretty small time ammunition even by modern earth missiles, which requires a long running sequence of repeated flybys.  The objective, IIRC was to destroy a critical piece of machinery on the surface which would then destabilize the entire planet/weapon (feel free to correct in edit if I remember incorrectly).  OK cool, but then why the force wouldn't they just drop a nuclear bomb on it?  Have nuclear weapons been used any other time in Star Wars (including EU), or, like smart phones, have they just not been invented in that world? Let's fix some terminology first. A category $\mathcal{C}$ is preabelian if:  1) $Hom_{\mathcal{C}}(A,B)$ is an abelian group for every $A,B$ such that composition is biadditive,  2) $\mathcal{C}$ has a zero object,  3) $\mathcal{C}$ has binary products,  4) $\mathcal{C}$ has kernels and cokernels.  A category $\mathcal{C}$ is abelian if it is preabelian and satisfies:  5) every monomorphism is a kernel and every epimorphism is a cokernel.  Define the coimage of a map to be the cokernel of its kernel, and the image to be the kernel of its cokernel. We have the following commutative diagram:    where $\overline{f}$ is the only existing map (because of universality of kernel and cokernel).  I'm having trouble proving the following:     A preabelian category $\mathcal{C}$ is abelian iff $\overline{f}$ is an isomorphism.   The converse is easily shown, I'm having trouble proving $\Rightarrow$... QGIS Atlas generation for multiple map extents? Unzipping geoprocessing package (GPK) file? I was under the impression that all ArcGIS package files could have their contents examined and potentially used by renaming them to *.zip and unzipping them.  This impression is supported for map package (*.mpk) files by  to  and I thought I had used it succesfully on geoprocessing package (*.gpk) files in the past.  However, today I am unable to use a  which I think is because it was created using ArcGIS Desktop 10.5.x when I am using 10.2.1.01. When I rename this *.gpk as *.zip and try to examine it in Windows Explorer I get:     Compressed (zipped) Folders Error      Windows cannot open the folder      The Compressed (zipped) Folder ....zip is invalid.     Is it possible to unzip a geoprocessing package (*.gpk) file to see whether it may contain some useful ArcPy code when that *.gpk cannot be unpacked to provide a usable toolbox? What's the fastest and easiest to read implementation of calculating the sum of digits?  I.e. Given the number: 17463 = 1 + 7 + 4 + 6 + 3 = 21 I changed both the desktop and login screen background photos. However,only desktop photo is changed. The one on the login screen is still the purple Ubuntu one. Is this a bug? The following MWE compiles (for me)  \documentclass{article}  \usepackage{pgfplots} \pgfplotsset{compat=newest} \usetikzlibrary{external} \tikzexternalize[prefix=figures/externalized/]   \begin{document} \begin{figure}     \centering     \begin{tikzpicture}          \begin{axis}  %           \addplot3[surf,mesh/rows=129,mesh/cols=129,mesh/ordering=y varies] table[x=X,y=Y,z=psi] {figures/data/LidDrivenCavity/Lid_SPIKE_128x128_Re1000_psi.dat};              \addplot3[contour gnuplot,mesh/rows=129,mesh/cols=129,mesh/ordering=y varies] table[x=X,y=Y,z=psi] {figures/data/LidDrivenCavity/Lid_SPIKE_128x128_Re1000_psi.dat};          \end{axis}      \end{tikzpicture}     \caption{ciao} \end{figure} \end{document}   where the data file is .

My TeX distribution is TeX Live on Mac OS X 10.9.5 and I use TeXShop as editor.  Once I (partially) solved a  on Windows+MikTeX+TeXniccenter by modifying/adding options to the command executed when compile button is pressed. I say partially since I actually solved the problem for some data file. Then I experienced the same problem with larger datafile and/or different plots (I don't remember anymore) and didn't find a way out, no matter how much I extended the memory.  What should I do now? How do I rename all folders and files to lowercase on Linux? I have to rename a complete folder tree recursively so that no uppercase letter appears anywhere (it's C++ source code, but that shouldn't matter).  Bonus points for ignoring CVS and Subversion version control files/folders. The preferred way would be a shell script, since a shell should be available on any Linux box.  There were some valid arguments about details of the file renaming.   I think files with the same lowercase names should be overwritten; it's the user's problem. When checked out on a case-ignoring file system, it would overwrite the first one with the latter, too. I would consider A-Z characters and transform them to a-z, everything else is just calling for problems (at least with source code). The script would be needed to run a build on a Linux system, so I think changes to CVS or Subversion version control files should be omitted. After all, it's just a scratch checkout. Maybe an "export" is more appropriate. Automatically put PGFPlots xtick scale label in x axis label I'm trying to put xtick scale label (defined by pgfkey /pgfplots/xtick scale label code/.code) in x axis label, between variable name and unit.  I've tried executing using the option xlabel = {$ x $ (\pgfkeysvalueof{/pgfplots/xtick scale label code/.code} m)} to put in but this doesn't work.  I've also tried the following xtick scale label code/.code={\pgfkeyssetvalue{/pgfplots/xlabel}{#1}} to force PGFPlots to change my xlabel but it doesn't work as well.  I know I can do this by hand, but I'm interested in automatic approach. Is there a workaround or a solution to this?  My MWE is:  \documentclass{article} \usepackage{pgfplots} \pgfplotsset{compat=1.14}  \begin{document}      \begin{tikzpicture}     \begin{axis}[         scaled x ticks=true,         scaled y ticks = false,         y tick label style={/pgf/number format/fixed},         %xtick scale label code/.code={\pgfkeyssetvalue{/pgfplots/xlabel}{#1}},         xlabel = {$ x $ (\pgfkeysvalueof{/pgfplots/xtick scale label code/.code} m)},         ylabel = {$ y $},     ]      \addplot[line width=3pt] coordinates {(0.0,0.0)(100,1)(400,2)(10000,0)};      \end{axis}     \end{tikzpicture}  \end{document}   Output from this code is: Show that $(1+\frac{x}{n})^n \rightarrow e^x$ uniformly on any bounded interval of the real line. Show that $(1+\frac{x}{n})^n \rightarrow e^x$ uniformly on any bounded interval of the real line.   I am trying to argue from the definition of uniform convergence for a sequence of real-valued functions, but am struggling quite a lot. My efforts so far have concentrated on trying to find a sequences, ${a_n}$ which tends to zero, such that   $$|(1+\frac{x}{n})^n -e^x |\leq a_n$$ for all $n$. But I have been unsuccessful thus far.
