QUESTION
I wrote a demo with some inline assembly (showing how to shift an array of memory right one bit) and it compiles and functions fine in GCC. However, the with Clang, I'm not sure if it's generating bad code or what but it's unhappy that I'm using memory despite the "rm" constraint.
I've tried many compilers and versions via Godbolt and while it works on all x86/x86_64 versions of GCC, it fails with all versions of Clang. I'm unsure if the problem is my code or if I found a compiler bug.

...ANSWER
Answered 2021-Jun-16 at 00:48I'm unsure if the problem is my code or if I found a compiler bug.
The problem is your code. In GNU assembler, parentheses are used to dereference like unary *
is in C, and you can only dereference a register, not memory. As such, writing 12(%0)
in the assembly when %0
might be memory is wrong. It only happens to work in GCC because GCC chooses to use a register for "rm"
there, while Clang chooses to use memory. You should use "r" (bytes)
instead.
Also, you need to tell the compiler that your assembly is going to modify the array, either with a memory
clobber or by adding *(unsigned char (*)[16])bytes
as an output. Right now, it's allowed to optimize your printf
to just hardcode what the values were at the beginning of the program.

QUESTION
I am trying to configure github webhooks with my jenkins server but I keep getting "failed to connect". Note that I am using a public ip and not a private or localhost address, At first, icmp protocol was blocked on my firewall but even after allowing it, it still doesn't work.
However, when I proxy my server (using smee client) and use the proxied url in the webhook instead, it works fine, so I thought the problem was jenkins url (in system configuration of jenkins) so I changed that to the public ip but it doesn't have any effect, now I'm clueless.
It might be relevant to mention that jenkins is running on a docker container,
...ANSWER
Answered 2021-Jun-15 at 23:51Apparently the webhook must pass through a web server and not to jenkins directly, So I configured nginx as a reverse proxy to jenkins server and it worked fine.
QUESTION
I am trying to define a subroutine in Raku
whose argument is, say, an Array of Ints (imposing that as a constraint, i.e. rejecting arguments that are not Array
s of Int
s).
Question: What is the "best" (most idiomatic, or straightforward, or whatever you think 'best' should mean here) way to achieve that?
Examples run in the Raku
REPL follow.
What I was hoping would work
...ANSWER
Answered 2021-Jun-15 at 06:40I think the main misunderstanding is that my Int @a = 1,2,3
and [1,2,3]
are somehow equivalent. They are not. The first case defines an array that will only take Int
values. The second case defines an array that will take anything, and just happens to have Int
values in it.
I'll try to cover all versions you tried, why they didn't work, and possibly how it would work. I'll be using a bare dd
as proof that the body of the function was reached.

My app consists in letting you add lists in which you can keep your notes. Therefore, I have this NotesListActivity where I can add and keep my Lists. I wanted to filter this lists following the https://www.youtube.com/watch?v=CTvzoVtKoJ8 tutorial and then I tried to adapt it to my code like below. Could you please tell me what is the problem here, cause I don't even get an error, I just not get any title of list as result. So, this is what I have in my RecyclerAdapter:

Answered 2021-Jun-13 at 20:18The problem is that you are using an empty notesListAll
list for filtering results; you need to populate it with the list of notes in the constructor

I'm trying to help a developer who is trying to harden a web server against server-side request forgery.

I have the below requirement . i am trying to run the condition in loop and its taking more time. is there a one time command anything which will not take more time to process a 70 MB file.
Requirement: if @pRECTYPE="SBSB" line contains @pSBEL_MCTR_RSN="XXX" tag then we need to copy and append that to next @pRECTYPE="SBEL record at the end of the line
File :note : in file there will be no blank lines. I have given enter to avoid line continuation

example :
Before : @pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX

@pRUKE=dfgt@pRECTYPE="SBEL", @pSBEL_EFF_DT="01/01/2017", @pCSPI_ID="JKOX0001", @pSBEL_FI="A"
After:
@pRUKE=dfgt@pRECTYPE="SMDR", @pCONFIG="Y" XXXXXXX
@pRUKE=dfgt@pRECTYPE="SBSB", @pGWID="1234", @pSBEL_MCTR_RSN="KX28", @pSBSB_9000_COLL=""

if after SBSB, if there is no SBEL, then that SBSB can be ignored.
what i did is egrep -n "pRECTYPE="SBSB"|pRECTYPE="SBEL"" filename | sed '$!N;/pRECTYPE="SBEL"/P;D' | awk -F: '{print $1}' | awk 'NR%2{printf "%s,",$0;next;}1' > 4.txt;
by this i will get the line number eg: 2,4 17,19
line 9 12 14 will be ignored

QUESTION
I would like to extract the definitions from the book The Navajo Language: A Grammar and Colloquial Dictionary by Young and Morgan. They look like this (very blurry):
I tried running it through the Google Cloud Vision API, and got decent results, but it doesn't know what to do with these "special" letters with accent marks on them, or the curls and lines on/through them. And because of the blurryness (there are no alternative sources of the PDF), it gets a lot of them wrong. So I'm thinking of doing it from scratch in Tesseract. Note the term is bold and the definition is not bold.
How can I use Node.js and Tesseract to get basically an array of JSON objects sort of like this:
...ANSWER
Answered 2021-Jun-15 at 20:17Tesseract takes a lang
variable that you can expand to include different languages if they're installed. I've used the UB Mannheim (https://github.com/UB-Mannheim/tesseract/wiki) installation which includes a ton of languages supported.
To get better and more accurate results, the best thing to do is to process the image before handing it to Tesseract. Set a white/black threshold so that you have black text on white background with no shading. I'm not sure how to do this in Node, but I've done it with Python's OpenCV library.
If that font doesn't get you decent results with the out of the box, then you'll want to train your own, yes. This blog post walks through the process in great detail: https://towardsdatascience.com/simple-ocr-with-tesseract-a4341e4564b6. It revolves around using the jTessBoxEditor to hand-label the objects detected in the images you're using.
Edit: In brief, the process to train your own:
- Install jTessBoxEditor (https://sourceforge.net/projects/vietocr/files/jTessBoxEditor/). Requires Java Runtime installed as well.
- Collect your training images. They want to be .tiffs. I found I got fairly accurate results with not a whole lot of images that had a good sample of all the characters I wanted to detect. Maybe 30/40 images. It's tedious, so you don't want to do TOO many, but need enough in order to get a good sampling.
- Use jTessBoxEditor to merge all the images into a single .tiff
- Create a training label file (.box)j. This is done with Tesseract itself.
tesseract your_language.font.exp0.tif your_language.font.exp0 makebox
- Now you can open the box file in jTessBoxEditor and you'll see how/where it detected the characters. Bounding boxes and what character it saw. The tedious part: Hand fix all the bounding boxes and characters to accurately represent what is in the images. Not joking, it's tedious. Slap some tv episodes up and just churn through it.
- Train the tesseract model itself
- save a file:
font_properties
who's content isfont 0 0 0 0 0
- run the following commands:
tesseract num.font.exp0.tif font_name.font.exp0 nobatch box.train
unicharset_extractor font_name.font.exp0.box
shapeclustering -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
mftraining -F font_properties -U unicharset -O font_name.unicharset font_name.font.exp0.tr
cntraining font_name.font.exp0.tr
You should, in there close to the end see some output that looks like this:
Master shape_table:Number of shapes = 10 max unichars = 1 number with multiple unichars = 0
That number of shapes should roughly be the number of characters present in all the image files you've provided.
If it went well, you should have 4 files created: inttemp
normproto
pffmtable
shapetable
. Rename them all with the prefix of your_language
from before. So e.g. your_language.inttemp
etc.
Then run:
combine_tessdata your_language
The file: your_language.traineddata
is the model. Copy that into your Tesseract's data folder. On Windows, it'll be like: C:\Program Files x86\tesseract\4.0\tessdata
and on Linux it's probably something like /usr/shared/tesseract/4.0/tessdata
.
Then when you run Tesseract, you'll pass the lang=your_language
. I found best results when I still passed an existing language as well, so like for my stuff it was still English I was grabbing, just funny fonts. So I still wanted the English as well, so I'd pass: lang=your_language+eng
