Using tecnickcom/tc-lib-barcode to generate QR codes - composer-php

I have installed the tc-lib-barcode library on Win10 localhost (using composer) and on a remote operational server to generate QR codes. It works great on the Win10 localhost, but not on the remote server.
The problem is that on the remote server the code line "$imageData = $bobj->getPngData();" causes it to freeze. I am guessing that the problem is something to do with the installation (removed and re-installed several times) or with PHP extensions and I stuck for a test that will point to the actual problem. Any comments or tips would be appreciated.
Here is the essential code I am using:
require ('../../vendor/autoload.php');
$barcode = new \Com\Tecnick\Barcode\Barcode();
$bobj = $barcode->getBarcodeObj('QRCODE,H', 'EditInvolvement.php?toID='.$InvolvementID, - 16, - 16, 'black', array(- 2, - 2, - 2, - 2))->setBackgroundColor('#f0f0f0');
$imageData = $bobj->getPngData();
file_put_contents('qr-code/'.$InvolvementID.'.png', $imageData); ```

Scipy.io.mmread Throws Value Error in Streamlit Heroku App

I have been trying to read a scipy matrix file in my streamlit app.
The app runs on local machine without any errors in app or console.
While deployed on Heroku it raises ValueError: not enough values to unpack (expected 5, got 2)
on the line co_occurrence_matrix = scipy.io.mmread("./database/matrix.mtx").
I've crosschecked the following points, and not sure where to look for the problem.
Matrix is created with
smatrix = scipy.sparse.csr_matrix(matrix)
scipy.isspmatrix(smatrix) #-> returns True
scipy.io.mmwrite("./database/matrix.mtx\",smatrix)
All library versions including python itself are identical between the two apps. Both checked on consoles with pip list. And requirements file is created with pip freeze.
Files are synchronized on git, git status returns 'up to date. Heroku uses the file on git, the local app runs on the synchronized file.
If it makes any difference, the .mtx file is uploaded via git lfs.
Heroku deploys the app successfully, yet inside the streamlit app, it gives the error.
Full Error:

As for the source of the problem: It is clearly stated in the Heroku docs that Heroku does not support git-lfs files. I've missed that point.
As a workaround, there are multiple build packs in Heroku elements. FYI, those buildpacks are also limited with Heroku's 500Mb filesize cap. And security has to be considered as an issue as those buildpacks require third-party access to your git.

Stable Diffusion Videos - DLL load failed while importing _ufuncs: %1 is not a valid Win32 application

I'm trying to run the Stable Diffusion Videos package and have installed the package and logged into Hugging Face. When I try to run the provided code from the package's GitHub page, I run into the ImportError: DLL load failed while importing _ufuncs: %1 is not a valid Win32 application. error. I have tried various solutions to this error but so far none of the solutions have worked.
I'm running Windows 11, 64 bit, and Python 3.10. I've read about missing dll files but am unsure how to find / install them to possibly fix this problem.

spyder: Windows permission errors when saving script

We've been trying to get spyder 5.1.5 to work inside a windows server environment (version 2012 and 2016). Before We've been using Spyder 3.3.6 successfully, but we want to upgrade to get "black/autopep8" autoformatting.
We have this distributed CIFS-like shared drive inside this server that has some strict permissions (but my username definitely has read/write/modify access at the level where the script is).
Unfortunately, when I try to get spyder to SAVE my code (and autoformat using black), I get the following (trimmed) error below. Basically spyder cannot save due to a permission error that doesn't make sense to me.
2021-12-08 18:23:52,005 [DEBUG] [spyder.plugins.completion.providers.languageserver.client] -> python Response error: {'code': -32602, 'message': "PermissionError: [WinError 5] Access is denied: '\\\\\\\\data-dist\\\\DataVol_014\\\\group\\\\users\\\\myusername\\\\myscript.py'", 'data': {'traceback': [' File "C:\\ProgramData\\Anaconda3\\envs\\py37-dev\\lib\\site-packages\\pylsp_jsonrpc\\endpoint.py", line 116, in consume\n self._handle_request(message[\'id\'], message[\'method\'], message.get(\'params\'))\n', '
Troubleshooting this further, I certainly have read/write/modify access to the following levels of this path:
\\data-dist\DataVol_014\group\users\myusername\myscript.py
\\data-dist\DataVol_014\group\users\myusername\
\\data-dist\DataVol_014\group\users\
However, I cannot even view this level:
\\data-dist\DataVol_014\group\
Still this does not make sense to me. I don't understand why spyder would need this level of access.
Any help/guidance is appreciated.
The error certainly goes away if I copy the script to a local drive on said server and the black autoformatting works as expected.

Portable Browser Issues when deploying R Shiny App

I've built a complex Shiny interface that pulls from an internally networked ODBC table and allows a user to interact with the data through their browser. The company is on Windows 7 Enterprise and IT only supports IE 9. Some users have chrome installed in their user folders, some have firefox, some use IE 9. I followed a tutorial from R-Bloggers (here: http://www.r-bloggers.com/deploying-desktop-apps-with-r/) and it runs on my machine using a portable Chrome browser downloaded from PortableApps.com. Great. Unfortunately the interface has not started on ANYONE else's machine that has their own local Chrome browser installed.
Following the tutorial, I use the following vb script:
Rexe = "R-Portable\App\R-Portable\bin\Rscript.exe"
Ropts = "--no-save --no-environ --no-init-file --no-restore --no-Rconsole"
RScriptFile = "runShinyApp.R"
Outfile = "ShinyApp.log"
strCommand = Rexe & " " & Ropts & " " & RScriptFile & " 1> " & Outfile & " 2>&1"
intWindowStyle = 0 ' Hide the window and activate another window.'
bWaitOnReturn = False ' continue running script after launching R '
CreateObject("Wscript.Shell").Run strCommand, intWindowStyle, bWaitOnReturn
This script calls the following code in my R file:
message('library paths:\n', paste('... ', .libPaths(), sep='', collapse='\n'))
chrome.portable = file.path(getwd(),'GoogleChromePortable/App/Chrome-bin/chrome.exe')
launch.browser = function(appUrl, browser.path=chrome.portable) {
message('Browser path: ', browser.path)
shell(sprintf('"%s" --app=%s', browser.path, appUrl))
}
shiny::runApp('shiny', launch.browser=launch.browser)
It works on my computer just fine... I DO have chrome installed locally, but I'm calling the Portable Chrome executable. It worries me that the two are sharing prefs or something, e.g. I notice that a hash from the Preferences file in my installed version, specifically:
"chrome_url_overrides": {
"bookmarks": [ "chrome-extension://eemcgdkfndhakfknompkggombfjjjeno/main.html" ]
},
...matches the same json entry from the Portable Chrome installation:
"chrome_url_overrides": {
"bookmarks": [ "chrome-extension://eemcgdkfndhakfknompkggombfjjjeno/main.html" ]
}
Why do these long random strings match? Am I barking up the wrong tree for wondering about this? I don't know why these strings match if they are two separate installations of Chrome executables, one of which is supposed to run completely independently from anything on the machine.

It seems like Chrome is doing different things on different computers and is not actually acting as a standalone browser... but likely interacting with the browser installed on their respective computers via the registry or some other "under the hood, active" communication. Maybe, since I installed the portable executable on my machine, a bunch of my local extensions or preferences were automatically updated to the portable's preferences, etc. and subsequently this is causing a conflict on every other machine??
Can I shutdown Chrome's extensions or extra functions like the calls to the updater? Is there a better standalone portable browser that functions well with Shiny for this type of "deployment" purpose? Can I fix this or is this a lost cause?? This should be obvious but I'll say it anyway: it is definitely not economically efficient to ask the non-technical types to install R, then RStudio, then confirm their working directory structure, then call the runApp() command via the Script window...
I started with those same articles, but developed the RInno package to solve this exact problem, i.e. when you want to share your desktop Shiny app with non-technical users who can't be expected to mess around with all those details.
To get started:
install.packages("RInno")
require(RInno)
RInno::install_inno()
Then you just need to call two functions to create an installation framework:
create_app(app_name = "myapp", app_dir = "path/to/myapp")
compile_iss()
This will create an installation wizard that runs like any other program, but installs your shiny app on a Windows desktop computer. If you would like to include R for your co-workers who don't have it installed, add include_R = TRUE to create_app:
create_app(app_name = "myapp", app_dir = "path/to/myapp", include_R = TRUE)
It defaults to include shiny, magrittr and jsonlite, so if you are using other packages like ggplot2 or plotly, just add them to the pkgs argument. You can also include GitHub packages to the remotes argument:
create_app(
app_name = "myapp",
app_dir = "path/to/myapp"
pkgs = c("shiny", "jsonlite", "magrittr", "plotly", "ggplot2"),
remotes = c("talgalili/installr", "daattali/shinyjs"))

Getting error when using facebook authentication in codeigniter

I am using Facebook-Oauth. I am using windows 7 and i am trying to run it in my localserver. I am setting site-url :http://www.domain.com and canvas url : http://www.domain.com/ . I didn't make change any other change in settings in the facebook developer site.But whenever i am trying to run it in my localhost i am getting this error :

2.Message: Use of undefined constant CURLAUTH_BASIC - assumed 'CURLAUTH_BASIC'

$config['facebook_api_key'] = '424824207643973';
$config['facebook_secret_key'] = 'my-app-secretkey';
cURL is most likely not installed correctly or linked up to PHP. Windows does not come with cURL installed (another reason to switch to a *nix based system! but I digress) so you'll need the appropriate dll files to enable it, then link those in via your php.ini file.
With regards to your current error, please check for syntax errors and leave a comment on this answer and update your provided source, and I'll modify.
