How to set render engine in blender? In MySql, find strings with a given prefix Often, crontab scripts are not executed on schedule or as expected. There are numerous reasons for that:   wrong crontab notation permissions problem environment variables   This community wiki aims to aggregate the top reasons for crontab scripts not being executed as expected. Write each reason in a separate answer.  Please include one reason per answer - details about why it's not executed - and fix(es) for that one reason.  Please write only cron-specific issues, e.g. commands that execute as expected from the shell but execute erroneously by cron. Is it correct to use "their" instead of "his or her"? Someone who just thinks they know what they're talking about Why does Lang describe a field as a union and compositum of its subfields in this manner? I am reading Serge Lang's Algebra, revised 3rd edition, and on page 226, the author makes the following definitions and observations:   If $E,F \subset L$, the compositum of $E$ and $F$ in $L$ is defined to be the smallest subfield of $L$ containing both $E$ and $F$. It is denoted $EF$. If $k \subset E$ and $\alpha_1,\dots,\alpha_n \in E$, then $k(\alpha_1,\dots,\alpha_n)$ is defined to be the smallest subfield of $E$ containing $k$ and $\alpha_1,\dots,\alpha_n$. Observe that $$ E = \bigcup k(\alpha_1,\dots,\alpha_n), $$ where the union is taken over all finite families $\{ \alpha_1,\dots,\alpha_n \}$ of elements of $E$. The compositum of an arbitrary family of subfields of a field $L$ is defined as the smallest subfield of $L$ containing all fields in the family. $E$ is finitely generated over $k$ if there is a finite family $\{ \alpha_1,\dots,\alpha_n \}$ of elements of $E$ such that $E = k(\alpha_1,\dots,\alpha_n)$. Observe that $E$ is the compositum of all its finitely generated subfields over $k$.   My question is regarding the two observations (point nos. 3 and 6). It appears to me that it is enough to take union (and compositum) over all subfields generated by a single element. For example for point no. 3, I can write $$ E = \bigcup_{\alpha \in E} k(\alpha) $$ because $E$ is clearly contained in the RHS, and each $k(\alpha)$ is contained in $E$ and hence so is the union, implying that $E$ contains the RHS. Similarly for point no. 6.  So, why does Lang emphasise to take the union and compositum over all finitely generated subfields? Is there some perspective that he wishes to emphasise that I am missing? Any help in understanding this will be appreciated. How can I find my Bug-report that I submitted from the Desktop on launchpad?  I have found a partial solution to my own question:  The program that sends the Bug-reports from the desktop is called apport. It doesn't requires a launchpad account. The service whoopsie submits the Bug-Report directly to the server daisy.ubuntu.com (I'm not sure if those bugs actually appear on launchpad publicly.)  But I found my Bug-Report on my Harddisk in /var/crash/ .  From there I can copy and paste parts of the file to my opened bug on launchpad. Thanks for your tips.  Original question:  I had a severe bug, and I found someone with the same problem in launchpad. After I found a temporary fix I was able to submit the bug with the ubuntu-bug-reporter.  How can I find this ubuntu-bug-reporter generated bug-report in launchpad? I would like to combine those two bug-reports (mark as duplicate). Because the generated one has all the debug information and the other one has the description of this bug. I want to copy all images on my computer to a single folder I want to copy all images of any file extension like .jpg, .png, .gif, etc. from all folders and subfolders in my PC hard drive (which has two partitions) to a single folder.  The total number of images I have is 250,000. How to detect if a variable is an array I have a python script that checks file path names for corresponding files in a drive location. All of the inputs were originally hard coded, and it works well enough:      import arcpy     import os     shp = r"C:\Users\dotwell\Desktop\Locations.shp"     fields = ["ZdriveLoc"]     f = open (r"C:\Users\dotwell\Desktop\ValMapsTest.txt", "w")     cursor = arcpy.da.SearchCursor (shp, fields)         for row in cursor:             Roll=str(row[0])             if not os.path.exists(Roll):             f.write(Roll + os.linesep)       f.close()   I'm trying to create an ArcGIS script tool from this, and I've only had partial success. I can use   shp = arcpy.GetParameterAsText(0)   to allow the user to select the shapefile. I'd like to then have a drop down list of the fields in that shapefile for the user to select the field that contains the path names, but I can't get it to work. Can someone show me how to generate the drop down? Here's my latest try. It works, but requires the user to type in the field name. It would also be nice for the user to designate the output text file name and location.   import arcpy import os shapefile = arcpy.GetParameterAsText(0) field = arcpy.GetParameterAsText(1) f = open (r"C:\Users\dotwell\Desktop\ValMapsTemp.txt", "w") cursor = arcpy.da.SearchCursor (shapefile, field) for row in cursor:     Roll=str(row[0])     if not os.path.exists(Roll):         f.write(Roll + os.linesep)   f.close()   Here are the parameters in my ArcGIS script tool: Apply brace expansion in "reverse order" Financial proof to get a Schengen visa to France I am planning to apply for a Schengen visa to visit France. I have an attestation d'acceuil, but the visa requires I submit bank statement for the past 3 months. I can get this statement, but the problem is that my company has been paying my salary in cash for the past months, and I place the money into the account by myself.  Can I submit the following?   my accounting book (current account)  letter from the bank stating that I have money in it payslips for the past 3 months   Will that satisfy the financial requirements for the visa?

Laplace equation of composite function Suppose we have $f(x,y)$, which satisfies Laplaces equation: $\frac{\delta^2f}{\delta x^2}+\frac{\delta^2f}{\delta y^2}=0$  Does $f(\frac{x}{x^2+y^2},\frac{y}{x^2+y^2})$ also satisfy Laplace equation? I would like to pause a render that I have started, with the intention of resuming it at a later time (but during the same Blender session).  How can I do this?
