QUESTION
I have two dataframes which I want to merge by nearest date. There´re often the same date of df2 which fits to df1. Also there´re values of df2 which doesn´t fit to df1 at all. After merging I want to know the time difference between the merging dates. For example ship Sally fits to two Peaks, ship Carl to no one. I tried different solutions e.g. with data.table roll='nearest' function
...ANSWER
Answered 2022-Feb-07 at 10:56I suggest two approaches. The first uses a distance matrix and perform a left_join of df1 to df2. Namely the distance matrix is given by:

I'm making a simple checkers like game in druid. At this point I want to replace rectangles I used for prototyping with some pixel sprites. My initial plan was to try and load them in the root function I pass to
...ANSWER
Answered 2021-Nov-08 at 12:19I would advise you to use the image
crate, to load the image (you did not specify the format, so I used a RGBA png with 4 bytes per pixel in my example).
- Get the pixels from the image as a
Vec
- Draw those pixels using
ctx.make_image
andctx.draw_image
Here is a full example based on the custom_widget

QUESTION
I was given the task to create an NYC Guide project out of Python and Django. I am iterating through a nested dictionary to render boroughs, activities, and venues. The home page lists a handful of boroughs. The boroughs page lists a handful of activities in each borough. The activities page lists a handful of venues to select. My issue is when I click on one of the activities I receive a TracebackError. I am trying to at least render the venues page that has a simple 'VENUES PAGE' on it. I'd love any advice or feedback. This is my first Django project so forgive me if I didn't explain this thoroughly enough. Feel free to ask for further explanation! What I am ultimately trying to do is render an unordered list of venues for each activity in the activities page. I would like each li to be a url that takes me to the venue.html page. It doesn't have to render a specific venue. I can take it from there. I am stuck on this one step. I have already successfully rendered the borough and activities pages, and I have been able to loop through the activities, but when I click on a specific activity I get this error:
"TypeError at /brooklyn/beaches activity() missing 1 required positional argument: 'venues'"

QUESTION
Below is my setup. I am inserting a user in ElasticSearch and I am doing weighted fuzziness username searches. The problem is that the fuzziness could be... fuzzier? I show you what I mean, this code is my mapping:
...ANSWER
Answered 2021-Oct-15 at 21:34When querying text or keyword fields, fuzziness is interpreted as a Levenshtein Edit Distance — the number of one character changes that need to be made to one string to make it the same as another string.
The Levenshtein Edit Distance essentially is a way of measuring the difference between 2 string values.
You've set the fuzziness
parameter to AUTO
, which is a great default decision. However, for some short strings like yours, it can prove to be not as fuzzy as you'd want it to be.
This is because ElasticSearch (ES) will generate an edit distance based on the length of the string, which will determine how many edits away the string in the index is from your search query.
You haven't specified any specific low
or high
values so for piet
, as it's a 4 character string, only one edit will be allowed.
pietje
is actually two edits away - piet
needs a j
as well as an e
so it won't show up.
p13tje
is actually four edits away - it needs a j
, an e
, a change from 1
to i
& a change from 3
to e
so it also won't show up.
The maximum allowed Levenshtein Edit Distance for ES fuzzy searching is 2 (larger differences are far more expensive to compute efficiently and are not processed by the Lucene search engine which ES is based on) so to fix this, set fuzziness
to 2
manually.

QUESTION
I have a database file that looks like the following:
...ANSWER
Answered 2021-Mar-04 at 21:41Remember, code behind can use full file system - like any desktop code.
But if you going to use that file in the asp.net (web side), then you MUST be able to produce a valid URL path name.
So ALWAYS keep in mind the above:
Codebehind - path names are STANDARD windows file path names (and even "\" etc.).
Web pages - markup = valid URL's mapped by the web site.
If you confuse the above two concpets above? you be in for a world of pain by ignoring the above VERY simple idea.
So, you need TWO things to convert those path names to valid WEB links:
First up: The web server "site" needs rights and a "means" to point to a given folder in question.
So, you might have some say SAN or big network storage device - and you toss/place/have/put your files there.
Say like this:
QUESTION
I need to draw a two-dimensional grid of Squares with centered Text on them onto a (transparent) PNG file. The tiles need to have a sufficiently big resolution, so that the text does not get pixaleted to much.
For testing purposes I create a 2048x2048px 32-bit (transparency) PNG Image with 128x128px tiles like for example that one:
The problem is I need to do this with reasonable performance. All methods I have tried so far took more than 100ms to complete, while I would need this to be at a max < 10ms. Apart from that I would need the program generating these images to be Cross-Platform and support WebAssembly (but even if you have for example an idea how to do this using posix threads, etc. I would gladly take that as a starting point, too).
Net5 Implementation ...ANSWER
Answered 2021-Mar-03 at 11:54I was able to get all of the drawing (creating the grid and the text) down to 4-5ms by:
- Caching values where possible (
Random
,StringFormat
,Math.Pow
) - Using
ArrayPool
for scratch buffer - Using the
DrawString
overload accepting aStringFormat
with the following options:Alignment
andLineAlignment
for centering (in lieu of manually calculating)FormatFlags
andTrimming
options that disable things like overflow/wrapping since we are just writing small numbers (this had an impact, though negligible)
- Using a custom
Font
from theGenericMonospace
font family instead ofSystemFonts.DefaultFont
- This shaved off ~15ms
- Fiddling with various
Graphics
options, such asTextRenderingHint
andSmoothingMode
- I got varying results so you may want to fiddle some more
- An array of
Color
and theToArgb
function to create anint
representing the 4xbyte
s of the pixel's color - Using
LockBits
, (semi-)unsafe
code andSpan
to- Fill a buffer representing 1px high and
size * count
px wide (the entire image width) with theint
representing the ARGB values of the random colors - Copy that buffer
size
times (now representing an entire square in height) - Rinse/Repeat
unsafe
was required to create aSpan<>
from the locked bit'sScan0
pointer
- Fill a buffer representing 1px high and
- Finally, using GDI/native to draw the text over the graphic
I was then able to shave a little bit of time off of the actual saving process by using the Image.Save(Stream)
overload. I used a FileStream
with a custom buffer-size of 16kb (over the default 4kb) which seemed to be the sweet spot. This brought the total end-to-end time down to around 40ms (on my machine).
QUESTION
I'm trying to figure how the atomic store functions in the following code work, they rely on GL_KHR_memory_scope_semantics
.
ANSWER
Answered 2021-Feb-11 at 04:14The specification you linked to seems pretty clear:
gl_StorageSemantics* and gl_Semantics* values should be bitwise ORed together to generate the SPIR-V Semantics enums
And it also specifies how the GL atomic functions map to SPIR-V atomic operations. So the answers you seek are in the SPIR-V specification. And the deep details are defined by the Vulkan memory model, appendix B of the Vulkan specification.
