Getting each foreach loop in ajax Posted: 30 May 2022 03:30 PM PDT I'm currently looking at making a social media style site. I have a foreach displaying a sql table of user posts. I've looked and found how to submit to a php file without refreshing but now I'm in need of a way to have the ability to like each individual post. Currently, if I put the ajax script at say the bottom, it likes the last post within the foreach loop. Any suggestions on how I can have it "like" the correct post? Hopefully this explains enough. My ajax code: $(document).ready(function(e){ e.preventDefault(); $.ajax({ url: "get_data.php", type: "POST", data: {postid, $postid}, success: function(data){ }); });

Group by using COUNT(*) OVER (PARTITION BY Posted: 30 May 2022 03:29 PM PDT I want to create a new column with the counts of repeated elements based on other 3 columns. When I try on the group by to add, i_count I get the following error SQL state: 42P20. I would also like to have a column with the average of the column loss from other column by name SELECT cst, st, co, COUNT(*) OVER (PARTITION BY cst,st,co ) AS count --mean of loss by co FROM s.tb_st , s.tb_cst , s.tb_co , erp.tb_i WHERE st != 'te' GROUP BY cst,st ,co, count ORDER BY cst , st, co; input cst | st | co sal | pa | ctr sal | pa | ctr sal | pa | est sal | re | ctr sal | re | ctr sal | re | ust cus | pa | ctr cus | re | ctr cus | re | ctr cus | re | ctr expected output cst | st | co |count | lossmeanbyco sal | pa | ctr | 2 | 2000 sal | pa | est | 1 | 5000 sal | re | ctr | 2 | 2000 sal | re | ust | 1 | 1000 cus | pa | ctr | 1 | 2000 cus | re | ctr | 3 | 2000

How to create a global variable for render_template()? Posted: 30 May 2022 03:29 PM PDT I have a simple task: to pass the same variable for different routes in the render_template() function. This value is in the base template and I need to pass it on every render_template() function. Can I set this value as a global value so that I don't have to set it in every function for different routes? @app.route('/hello') def hello(name=None): return render_template('hello.html', value=value) @app.route('/bye') def bye(name=None): return render_template('bye.html', value=value)```

Dynamic text on image Posted: 30 May 2022 03:29 PM PDT I have an application that creates a dynamic image and writes text on it. The English language text works as advertised but other languages fail completely. The letters become boxes, etc. package main import ( "errors" "fmt" "image" "image/color" "image/png" "math" "os" "github.com/fogleman/gg" guuid "github.com/google/uuid" "github.com/jimlawless/whereami" ) type TextImage struct { BgImgPath string FontPath string FontSize float64 Text string } var sentence = make(map[string]string) var language string func init() { sentence["arabic"] = "قفز الثعلب البني فوق الكلب الكسول." sentence["english"] = "The brown fox jumped over the lazy dog." sentence["hebrew"] = "השועל החום קפץ מעל הכלב העצלן." sentence["hindi"] = "भूरी लोमड़ी आलसी कुत्ते के ऊपर से कूद गई।." sentence["greek"] = "Η καφέ αλεπού πήδηξε πάνω από το τεμπέλικο σκυλί." } func main() { language = "greek" uuid := genUUID() createFolder(uuid) createImage(len(sentence[language]), uuid) writeImage(sentence[language], uuid) } func genUUID() string { return guuid.New().String() } func createFolder(p string) { path := "./tmp/" + p if _, err := os.Stat(path); errors.Is(err, os.ErrNotExist) { err := os.MkdirAll(path, os.ModePerm) if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } } } func writeImage(text string, path string) { ti := TextImage{ BgImgPath: "./tmp/" + path + "/" + language + ".png", FontPath: "./ttf/PlayfairDisplay-Regular.ttf", FontSize: 24, Text: text, } img, err := textOnImg(ti) if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } err = saveImage(img, "./tmp/"+path+"/"+language+".png") if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } } func createImage(textlength int, path string) { minDim := 300 scale := 30 dim := math.Sqrt(float64(textlength)) width := int(dim) * scale height := int(dim) * scale if width < minDim || height < minDim { width = minDim height = minDim } upLeft := image.Point{0, 0} lowRight := image.Point{width, height} img := image.NewRGBA(image.Rectangle{upLeft, lowRight}) //img.Bounds() white := color.RGBA{255, 255, 255, 0xff} // Set color for each pixel. for x := 0; x < width; x++ { for y := 0; y < height; y++ { switch { case x < width/2 && y < height/2: // upper left quadrant img.Set(x, y, white) case x >= width/2 && y >= height/2: // lower right quadrant img.Set(x, y, color.White) default: img.Set(x, y, color.White) } } } f, err := os.Create("./tmp/" + path + "/" + language + ".png") if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } err = png.Encode(f, img) if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } } func deleteFolder(folder string) { err := os.RemoveAll("./tmp/" + folder) if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) } } func textOnImg(ti TextImage) (image.Image, error) { bgImage, err := gg.LoadImage(ti.BgImgPath) if err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) return nil, err } imgWidth := bgImage.Bounds().Dx() imgHeight := bgImage.Bounds().Dy() dc := gg.NewContext(imgWidth, imgHeight) dc.DrawImage(bgImage, 0, 0) if err := dc.LoadFontFace(ti.FontPath, ti.FontSize); err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) return nil, err } x := float64(imgWidth / 2) y := float64((imgHeight / 2) - 80) maxWidth := float64(imgWidth) - 60.0 dc.SetColor(color.Black) fmt.Println(ti.Text) dc.DrawStringWrapped(ti.Text, x, y, 0.5, 0.5, maxWidth, 1.5, gg.AlignLeft) return dc.Image(), nil } func saveImage(img image.Image, path string) error { if err := gg.SavePNG(path, img); err != nil { fmt.Println(err.Error() + " @ " + whereami.WhereAmI()) return err } return nil } Any recommendations hot to fix this?

Trying to understand functions bool in C++ Posted: 30 May 2022 03:29 PM PDT I am a beginner in C++ and I'm trying to improve my programming with functions. My problem with the exercise below is with making a code for objective number 2, where I don't understand how to return a value true or else false for the given variables (y1, x1, c1) with the use of function bool three (int) and arguments y, x and c. I just really need to see a working code for exercise below so that I can then dive into it and learn from it, understanding what everything does. It would mean alot and help me move on to other function exercises. Every help is very much appreciated. This is the exercise: Create a program with proper functions. Read values for y, x and c; reading should repeat untill y is between 2 and 5 (with 2 and 5 included) and then x and c between 7 and 12 (both included). Function three (int) shuold return value true, if the given argument (value of variable) is multiple of number 3, else is false; with this function decide a value for variable y1 for argument y and similar for x1 for argument x and c1 for argument c. Type out values for y1, x1 and c1. Function odd (int, int) writes out all the odd numbers between 2 given arguments y and x. Function square (int,int,int,int&,int&) should return value, which is a sum of squares of the given arguments; over the last two arguments it should return a sum of squares of the first 2 arguments and the last 2 arguments. With function determine value of variable yxc with arguments y, x, c, yx2 and xc2. Write out values of yxc, yx2 and xc2 Prototypes of functions: bool three (int); void odd (int,int); int square (int,int,int,int&,int&); How my code looks like now: #include <iostream> using namespace std; bool three(int); void odd(int, int); int square(int, int, int, int&, int&); int main() { int y, x, c; cout << "Insert values for y, x in c." << endl; while ((y > 5) || (y < 2)) { cout << "Insert a value for y: "; cin >> y; } while ((x > 12) || (x < 7)) { cout << "Insert a value for x: "; cin >> x; } while ((c > 12) || (x < 7)) { cout << "Insert a value for c: "; cin >> c; } three(y); } bool three(int y) { if (y % 3 == 0) return true; else { return false; } }

Why is Android Studio telling me my variable is not initialized? Posted: 30 May 2022 03:28 PM PDT I am trying to change the location of an image, and to do that I need a certain variable, which I initialized at the start of this code. I am able to call the variable multiple times with no problem, expect for the second time I call it, on line 7. The exact error is "Variable 'currentHall' must be initialized." How can I fix this? var currentHall: Hall for(i in 0..11) { if(halls[i].name == locationHall) { currentHall = halls[i] } } if(currentHall.image == "segment_hori.png") { youAreHere.y = currentHall.yCoord youAreHere.x = currentHall.xCoord + locationCoords } if(currentHall.image == "segment_vert.png") { youAreHere.y = currentHall.yCoord + locationCoords youAreHere.x = currentHall.xCoord }

Rust: Mysterious impossibility of copy array Posted: 30 May 2022 03:28 PM PDT I wrote the following Rust code, and is giving me a error whose cause is far beyond my comprehension. And is that the array copy mechanism in lines 80 to 88, but that it is no working, and I have no idea why. Also note that I already tried with .copy. I just want to copy the Updater's display to the Canvas view_buffer. Why does the line 88 assert does crash?

How to get the first audio channel from a video with ffmpeg-python? Posted: 30 May 2022 03:27 PM PDT I would like to get the very first audio channel from a video using ffmpeg-python. I tried with this: out, _ = ( ffmpeg .input(filename) .output('pipe:', loglevel=0, format='s16le', acodec='pcm_s16le', ac=1, ar='8k') .run(capture_stdout=True) ) """ extract audio signal """ self.signal = ( np .frombuffer(out, np.int16) ) but I am not sure whether this is correct. I had a look here, but I could not find a solution: https://trac.ffmpeg.org/wiki/AudioChannelManipulation Any suggestion? Thanks!

Why does error No module named app keep coming up? Posted: 30 May 2022 03:29 PM PDT Not sure why I keep getting this error. The app.py seems to be in the right folder and there's no virtual env folder. Error (python.exe: No module named app) It is a Flask app. This is literally all of the code (It's a school project but I don't think the error is part of it): from flask import Flask, render_template import json """ A example for creating a Table that is sortable by its header """ app = Flask(__name__) data = [{ "name": "bootstrap-table", "commits": "10", "uneven": "An extended Bootstrap table" }, { "name": "multiple-select", "commits": "288", "uneven": "A jQuery plugin" }, { "name": "Testing", "commits": "340", "uneven": "For test" }] # other column settings -> http://bootstrap-table.wenzhixin.net.cn/documentation/#column-options columns = [ { "field": "name", # which is the field's name of data key "title": "name", # display as the table header's name "sortable": True, }, { "field": "commits", "title": "commits", "sortable": True, }, { "field": "uneven", "title": "uneven", "sortable": True, } ] #jdata=json.dumps(data) @app.route('/') def index(): return render_template("table.html", data=data, columns=columns, title='Flask Bootstrap Table') if __name__ == '__main__': #print jdata app.run(debug=True)

R: What is the difference of the Lasso for variable selection between the packages glmnet and hdm Posted: 30 May 2022 03:28 PM PDT For my PhD I use a Lasso approach in R for variable selection. Now, I used the package glmnet and also hdm. What is the difference of the basic lasso estimator in these two packages? I read the docs and also googled a lot but the only hint that I found was this one which was not very helpful for my exact purpose. The reason for asking is because my models converge if I use glmnet and they sometimes do not converge when I use hdm. That is why I assume that the difference is in the optimization function. Here is a minimal example: # Delete environment rm(list = ls()) # Packages library(glmnet) #> Loading required package: Matrix #> Loaded glmnet 4.1-4 library(hdm) # get data data = read.table("https://pastebin.com/raw/gmXk0h2P", sep = ",", header = T) # do the lasso lasso_hdm = rlassologit(dep ~ ., data = data) #> Warning: from glmnet C++ code (error code -1); Convergence for 1th lambda value #> not reached after maxit=100000 iterations; solutions for larger lambdas returned #> Warning in getcoef(fit, nvars, nx, vnames): an empty model has been returned; #> probably a convergence issue lasso_glm = glmnet(as.matrix(data[,!(names(data) %in% c("dep"))]), data$dep, family = "binomial") Created on 2022-05-31 by the reprex package (v2.0.1) Additionally, please find my sessionInfo: sessionInfo() #> R version 4.2.0 (2022-04-22) #> Platform: x86_64-pc-linux-gnu (64-bit) #> Running under: Ubuntu 22.04 LTS #> #> Matrix products: default #> BLAS: /usr/lib/x86_64-linux-gnu/blas/libblas.so.3.10.0 #> LAPACK: /usr/lib/x86_64-linux-gnu/lapack/liblapack.so.3.10.0 #> #> locale: #> [1] LC_CTYPE=en_GB.UTF-8 LC_NUMERIC=C #> [3] LC_TIME=de_DE.UTF-8 LC_COLLATE=en_GB.UTF-8 #> [5] LC_MONETARY=de_DE.UTF-8 LC_MESSAGES=en_GB.UTF-8 #> [7] LC_PAPER=de_DE.UTF-8 LC_NAME=C #> [9] LC_ADDRESS=C LC_TELEPHONE=C #> [11] LC_MEASUREMENT=de_DE.UTF-8 LC_IDENTIFICATION=C #> #> attached base packages: #> [1] stats graphics grDevices utils datasets methods base #> #> loaded via a namespace (and not attached): #> [1] rstudioapi_0.13 knitr_1.39 magrittr_2.0.3 R.cache_0.15.0 #> [5] rlang_1.0.2 fastmap_1.1.0 fansi_1.0.3 stringr_1.4.0 #> [9] styler_1.7.0 highr_0.9 tools_4.2.0 xfun_0.31 #> [13] R.oo_1.24.0 utf8_1.2.2 cli_3.3.0 withr_2.5.0 #> [17] htmltools_0.5.2 ellipsis_0.3.2 yaml_2.3.5 digest_0.6.29 #> [21] tibble_3.1.7 lifecycle_1.0.1 crayon_1.5.1 purrr_0.3.4 #> [25] R.utils_2.11.0 vctrs_0.4.1 fs_1.5.2 glue_1.6.2 #> [29] evaluate_0.15 rmarkdown_2.14 reprex_2.0.1 stringi_1.7.6 #> [33] compiler_4.2.0 pillar_1.7.0 R.methodsS3_1.8.1 pkgconfig_2.0.3 Created on 2022-05-31 by the reprex package (v2.0.1) In the end I am interested in the theory of both packages and maybe I find a good reason to stick to the glmnet package as this converges. Thank you so much in advance!

How do I modify a binary file in a shell script? Posted: 30 May 2022 03:28 PM PDT Is there a command to modify a binary file in the shell? First, I created a file with all 0xFF values: dd if=/dev/zero ibs=1K count=1 | tr "\000" "\377" > ./Test.img hexdump Test.img Output: 0000000 ffff ffff ffff ffff ffff ffff ffff ffff * 0000400 Then I wanted to change some byte value like 0000000 aaaa ffff bbbb ffff cccc ffff ffff ffff * 0000400 How can I change that? Or is there a command in shell script?
