Include API key as a URL query parameter via a Named Credential
Can I use Named Credential merge fields as URL parameters on the endpoint?
Create default home directory for existing user in terminal How do I do this? I created a user without a home directory and now I want to create one. Not just a folder called new_user, I want the default home directory with all it's folders and hidden files, etc. What are these fuse-looking cartridge case components on small, battery operated RF tranceivers? I have recently opened up 3 dead, battery-operated RF transceivers lying around, both wearable and key-chains. I've noticed that all three had components that looked like fuses (cartridge case), soldered down, that are quite large compared to the size of the circuit. See the pictures below. I'm not posting full circuit pictures because I don't know if I should, I can update if they are necessary.  Device 1:    Device 2:    Device 3:    I can't see why such a device will require a fuse, and I couldn't find any other common components manufactured in cartridge cases, maybe I'm not using the correct name. I don't see them on any applications notes or reference designs for the ICs used either.  I've tried to figure out how they are connected to the circuit, I don't have schematics and PCBs are more than 2 layers so they may not be complete, but see the schematics I've figured below.  Device 1:    Device 2:    Device 3:    Also, when I do a continuity test between the terminals of the components with a multimeter, resistance starts in ~50 Ohms range and goes down to short as I keep the probes on its terminals so my best guess is something for ESD protection, maybe Varistors or Thermistors?   Does anyone know what these components are and why they are there? Can Blender render pngs with the background transparent? I would like to render an animation as a series of .png images with transparent backgrounds for use in a video. Is this possible? What are examples of two non-similar invertible matrices with same minimal and characteristic polynomial and same dimension of each eigenspace? PlotLegends won't generate automatically more than 15 labels in v10 How to customize Windows 10 "6 Folders" in My Computer I would like to customize the folders in the Default Folders group of My computer. It is not necessary to have the same folders appear on the left sidebar and in the middle view. How can I do that ? DRAM Frequency showing 800 instead of 1600 I am running a Core i7 CPU originally at 3Ghz overclocked to 4Ghz using a multiplier of x20 and a Bus Speed of 200 Mhz  My memory is 1600 Mhz OCZ.  I installed CPU-Z to see what is going on - but it shows me (under the "Memory" Tab):  DRAM Frequency 800 Mhz  Channel Triple - NB Frequency 3800.2 Mhz  So what is the actual frequency its running on then? I am slightly confused. I am just looking for some clarification on this exercise:  Let $A = \{a,b,c,d\}$. Give an example of a relation $R$ on $A^2$ which is reflexive, symmetric, and not transitive.  I understand that if I was only dealing with $A$ and and not $A^2$ I could give an answer similar to:  $R = \{(a,a),(a,b),(a,d),(b,a),(b,b),(c,c),(d,a),(d,d)\}$  Here $R$ is reflexive, symmetric, and not transitive.  What is confusing me is the fact that we have $A^2$. I am not sure what I am missing here. I am looking through my book to see if I can figure this out, but if someone could help shed some light on this it would be appreciated.  Thanks,  Tony Using File Geodatabase coded domain with ArcGIS Online? I created a File GDB and set up a domain, and the domain was assigned to a field in a feature class. The domain behaves as expected on ArcGIS Desktop (dropdown list when editing the content of that field).  But if I zip up the FGDB and upload to ArcGIS Online to created a feature layer and edit the layer online, there is no dropdown when editing.  I don't see any additional step in this tutorial, other than a different mechanism of getting data to ArcGIS Online. I don't think I can do it the same way in ArcGIS 10.0:   Anyone has any idea what's going on? Are there 'stack' sites for Mac or Windows? Summing up the area on a polygon by a certain attribute result I wish to know if there's a tool on QGIS equivalent to the Excel's "SUMIF".    I have a shapefile of a land use and cover that's classified by the attribute with the name of the classes, for example: "vegetation", "urban centers" and "pastures". My goal is to calculate the area of each class, but since it's composed by various polygons, I need to add up all the areas from all polygons that were put in the same class.  Like I mentioned in the beginning of the question, I know that Excel has a function that can do such thing for me, but it turns out that the sum made by excel doesn't match the area's total given by QGIS.  English is not my first language, so if the explanation isn't clear enough, I'll be glad to rephrase it. Why exactly does diffraction occur? Why do waves that were traveling in a straight direction change direction when passing through an opening?  I thought that the waves (red arrow) when colliding with the wall bounce in the opposite direction (green arrow).  And the waves that pass through the aperture follow its path normally as shown in the image on the right.   The waves that go in a straight direction should follow traveling straight line like a car that goes under a bridge the car is straight on the road. But this is not so.  Why does the direction of the waves change?  How is the direction of the waves calculated? How to use figure inside a minipage? I'm trying to include an image, and keep it centered, and prevent from wrapping from the next page.  The following code works for that:  \begin{minipage}{\textwidth}     \begin{center}         Caption for image          \includegraphics[scale=0.5]{myimage.png}      \end{center} \end{minipage}   I'd like this image to be in a figure, with a caption.  The following doesn't compile:  \begin{minipage}{\textwidth}     \begin{figure}         \includegraphics[scale=0.5]{myimage.png}         \caption{Caption for image}         \label{fig:sample_figure}     \end{figure} \end{minipage}   I get the errors:  ! LaTeX Error: Not in outer par mode. ! Undefined control sequence.   How can I fix this? Selenium 2: Open link in new tab and close tabs How to filter features in a layer? I am trying to display certain features in a shapefile-based layer using QGIS. I have found the subset function in the properties panel, which does exactly what i want, but is too tedious given that I have to manually sift through a large number of features. Is there a quicker way to do this?  I am using both shapefiles and postGIS best,  dietmar I am looking to create some handwriting drill sheets.  Similar to what can be found here    I also found this question:  But I'd like to be able to simply write a paragraph of text with a known font and have the lines placed behind, perhaps like a watermark.  I have found a git repo with some nice lines in both portrait and landscape here   From the kindergarten example, I would like to overlay "phantom" text (probably a dotted cursive font) over the lines that are generated.

Consider the infinite line, $L$ in $2D$ consisting of all points $p$ such that $p.[0.3511 0.9263]= 6$. Find the point on the line closest to $(10, 20)$. Find the point on the line closest to $(4, 3)$. Find the distance from the line to both of these points.  Hi, I was reading the book $3D$ Maths Primer for Graphics and Game Development. The book mention about $2$ formulas but I don't know how to apply them.   $\text{Signed distance} = d-q.n$  $q' = q + (d-q.n)n$  for any point $q$, the point $q'$ that is the closest point on $L$ to $q$.  This is what I have tried,   Since the lines are parallel then the normal are the same so   $q' = q + (6 - q(0.3511 0.9263))(0.3511 0.9263)$   I'm stuck here. On a whim the other day, I changed my meta name from Lord Torgamus to Popular Demand.  I just noticed that the old name has "stuck" to the author tag of ; everywhere else on meta, my new name displays as expected.  Is this a feature?  Is it a bug?  Mostly I'm just curious, as I can't think of a strong reason in favor of keeping this behavior or a strong reason for changing it.  A question somewhat like this has been raised before as , but the previous poster implied that the issue had something to do with migration, which my situation shows is not the case.
