QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events
snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:
10:54:12.642 AM Function execution started
10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating
10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating
10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'

Super hyggelig aften :)
super oplevelse, ... long string generated
Gist showing the function in question
I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon

QUESTION
I have two Strings
"TOP : Cotton + Embroidered ( 2 Mtr) \nBOTTOM : Cotton + Solid (2 Mtr) \nDUPATTA : Chiffon + Lace Work ( 2 Mtr) \nTYPE : Un Stitched\nCOLOUR : Multi Colour \nCONTAINS : 1 TOP WITH LINING 1 BOTTOM & 1 DUPATTA\nCountry of Origin: India"
and Second one is
"Top Fabric: Cotton Cambric + Top Length: 0-2.00\nBottom Fabric: Cotton Cambric + Bottom Length: 0-2.00\nDupatta Fabric: Nazneen + Dupatta Length: 0-2.00\nLining Fabric: Cotton Cambric\nType: Un Stitched\nPattern: Printed\nMultipack: 3 Top\nCountry of Origin: India"
I need to create python dictionary out of these two strings but with keys which are before colon
for example in string one keys would be
TOP,BOTTOM,DUPATTA,TYPE,COLOUR,CONTAINS,COUNTRY OF ORIGIN
and in second one
keys would be
Top Fabric,Bottom Fabric,Top Length,Bottom Length,Dupatta Fabric,Dupatta Length,Lining Fabric,Type,Pattern,Multipack,Country of Origin
So far i have used
...ANSWER
Answered 2021-Jun-10 at 11:40You might use a regex pattern that matches the part before the colon in group 1 and after the colon in group 2.
Then assert that after group 2, there is either another part starting with a +
followed by :
or the end of the string.
Then create a dictionary, stripping the group 1 and group 2 values.
QUESTION
I'm trying to stitch two pre-warped images together seamlessly using multi-band blending. I have two input images (that have already been warped) and one mask. However, when I apply MBB, the area surrounding the seams glow brighter and as a result, they become more visible which is the opposite of the objective here. I have absolutely no idea what I'm doing wrong.
To better explain the problem, here are the images and the output:
Target:
Source:
Mask:
And once I blend the source image into the target, this is what I get:
Here's my code for reference:

QUESTION
I am doing an image stitching project using OpenCV. Now I have the homography H1 between img1 and img2, and the homography H2 between img2 and img3. Now I need to compute the homography between img1 and img3, simply multiply H1*H2 is not working.
Are any ideas to calculate the new homography between img1 and img3?
...ANSWER
Answered 2021-May-21 at 19:42for me computing H1 * H2
works well and gives the right results.
Here, H1 = H2_1
since it warps from image2 to image1.
H2 = H3_2
since it warps from image3 to image2.
H1 * H2 = H3_1
since it warps from image3 to image 1.
QUESTION
I'm preparing some html pages using rmarkdown
, intended for posting online. When showing plots, I'd like to take advantage of more of the width available on a typical computer monitor (which is how I anticipate my intended audience viewing my pages). knitr
by default only seems to use around 900 pixels at regular zoom.
I found some css in this thread which can make the total "canvas" bigger, which is helpful. However, this also increases the width of everything, including text, chunk echoes, etc, which I don't want. What I'd like is to have my figures "overhang" the other elements in width. Increasing fig.width
and out.width
doesn't accomplish this; the figures will simply shrink to fit within the same bounds used by the other elements, resulting in smaller font size, etc:
ANSWER
Answered 2021-May-21 at 21:40As you have realized, you should not increase the width of .main-container
, but the images instead. Below is one way to achieve it:
QUESTION
Is there any chance that I can fix my problem with my grid layout? I have the main layout which I used is a grid and it has 5 templates. I'm having a problem with the second row because I am using the same template row for my index and details page. The last row is the footer but it covers the content of the second row. How can I fix it? See the picture below for your reference.
This is the main template rows: grid-template-rows: 120px calc(100vh - 120px) repeat(2, 1fr) auto;
The calc(100vh - 120px) is the template row for hero main and blog details.

As you can see the footer covers the description. (The bug occur when you shrink the height of you window
...ANSWER
Answered 2021-May-15 at 11:40Replacing
your main's grid template rows into grid-template-rows: 120px auto repeat(2, 1fr) auto;
and adding a min-height
of calc(100vh - 120px);
to your blog-details-section
should do the trick
