QUESTION
I have been using github actions for quite sometime but today my deployments started failing. Below is the error from github action logs
...ANSWER
Answered 2022-Mar-16 at 07:01First, this error message is indeed expected on Jan. 11th, 2022.
See "Improving Git protocol security on GitHub".
January 11, 2022 Final brownout.
This is the full brownout period where we’ll temporarily stop accepting the deprecated key and signature types, ciphers, and MACs, and the unencrypted Git protocol.
This will help clients discover any lingering use of older keys or old URLs.
Second, check your package.json
dependencies for any git://
URL, as in this example, fixed in this PR.
As noted by Jörg W Mittag:
For GitHub Actions:There was a 4-month warning.
The entire Internet has been moving away from unauthenticated, unencrypted protocols for a decade, it's not like this is a huge surprise.Personally, I consider it less an "issue" and more "detecting unmaintained dependencies".
Plus, this is still only the brownout period, so the protocol will only be disabled for a short period of time, allowing developers to discover the problem.
The permanent shutdown is not until March 15th.
As in actions/checkout issue 14, you can add as a first step:
QUESTION
I need to upload a file (<10 MB) around once a week to a SQL Server 2016 database on a remote server in the same network. Until now it was all within a Access FE/BE but I want to migrate to SQL Server as backend.
The attachments I had in MS Access so need to be handled now on the SQL database as I do not want to do this on a fileshare.
I found many threads about using something like this from SQLShack
...ANSWER
Answered 2022-Mar-13 at 23:33I may have found a solution using the links from @AlwaysLearning. The first sub actually answers my question to upload a file to a remote FILESTREAM SQL Server. The second sub downloads all uploaded files into a given directory.
QUESTION
I have implemented a Convolutional Neural Network in C and have been studying what parts of it have the longest latency.
Based on my research, the massive amounts of matricial multiplication required by CNNs makes running them on CPUs and even GPUs very inefficient. However, when I actually profiled my code (on an unoptimized build) I found out that something other than the multiplication itself was the bottleneck of the implementation.
After turning on optimization (-O3 -march=native -ffast-math
, gcc cross compiler), the Gprof result was the following:
Clearly, the convolution2D
function takes the largest amount of time to run, followed by the batch normalization and depthwise convolution functions.
The convolution function in question looks like this:
...ANSWER
Answered 2022-Mar-10 at 13:57Looking at the result of Cachegrind, it doesn't look like the memory is your bottleneck. The NN has to be stored in memory anyway, but if it's too large that your program's having a lot of L1 cache misses, then it's worth thinking to try to minimize L1 misses, but 1.7% of L1 (data) miss rate is not a problem.
So you're trying to make this run fast anyway. Looking at your code, what's happening at the most inner loop is very simple (load-> multiply -> add -> store), and it doesn't have any side effect other than the final store. This kind of code is easily parallelizable, for example, by multithreading or vectorizing. I think you'll know how to make this run in multiple threads seeing that you can write code with some complexity, and you asked in comments how to manually vectorize the code.
I will explain that part, but one thing to bear in mind is that once you choose to manually vectorize the code, it will often be tied to certain CPU architectures. Let's not consider non-AMD64 compatible CPUs like ARM. Still, you have the option of MMX, SSE, AVX, and AVX512 to choose as an extension for vectorized computation, and each extension has multiple versions. If you want maximum portability, SSE2 is a reasonable choice. SSE2 appeared with Pentium 4, and it supports 128-bit vectors. For this post I'll use AVX2, which supports 128-bit and 256-bit vectors. It runs fine on your CPU, and has reasonable portability these days, supported from Haswell (2013) and Excavator (2015).
The pattern you're using in the inner loop is called FMA (fused multiply and add). AVX2 has an instruction for this. Have a look at this function and the compiled output.
QUESTION
I wanted to know how methods are implemented in C++. I wanted to know how methods are implemented "under the hood". So, I have made a simple C++ program which has a class with 1 non static field and 1 non static, non virtual method.
Then I instantiated the class in the main function and called the method. I have used objdump -d option in order to see the CPU instructions of this program. I have a x86-64
processor.
Here's the code:

I have set up VS code as my development environment and used
MSVC
build tools (cl.exe
compiler) instead of g++
. I tried to set up SFML
for my environment. I want to know how do I set the SFML
include path and library path. And also, How do I perform static Linking with cl.exe
. Note: I am using only VS code and NOT Visual Studio for programming. Below are some files I've used. Tasks.json
,Launch.json
, C_cpp_properties.json
.
Tasks.json:
...ANSWER
Answered 2022-Jan-13 at 13:55As mentioned in the comments, you need to use a C++ build system to manage dependencies and build your project. VSCode does not come with any built-in build systems like Visual Studio does.
VSCode tasks allow you to specify a command line, which can then be invoked easily in the IDE. The task shown is just a "build active file" task, which is only really useful for trivial programs with no dependencies. It invokes cl.exe
on the current source file (and passes a few other arguments).
You can specify include directories and pass arguments to the linker by adding to the "args" array in the task, e.g.:

[Editing this question completely] Thank you , for those who helped in building the Periodic Table successfully . As I completed it , I tried to link it with another of my project E-Search
, which acts like Google and fetches answers , except that it will fetch me the data of the Periodic Table .
But , I got a problem - not with the searching but with the layout . I'm trying to layout the x-scrollbar in my canvas which will display results regarding the search . However , it is not properly done . Can anyone please help ?
Below here is my code :
...ANSWER
Answered 2021-Dec-29 at 20:33I rewrote your code with some better ways to create table. My idea was to pick out the buttons that fell onto a range of type and then loop through those buttons and change its color to those type.
QUESTION
I have a message box at the bottom of my site. I don't know how these messages manage to slip through my validations.
These are the spam messages, that somehow able to submit to my database.
JS validation:
...ANSWER
Answered 2022-Jan-10 at 00:06No matter what code you put on the frontend, if an endpoint is visible to the client (for example, if it exists in the source code), it'll be possible for any client to send any information they want to that endpoint. Setting up client-side JavaScript validation is useful to improve the UI, but it doesn't improve the security of what's allowed to be submitted at all.
A good rule of thumb is: nothing that runs on the client is really secure, because the client can run any JavaScript code they want (and perhaps with a bot).
If you want to stop certain messages, you'll have to put the logic that tests for the submission's validity on the back-end, not only on the front-end - then only insert into the database if the back-end test passes.
QUESTION
So this seems to be an issue talked about here and there on StackOverflow with no real solution. So I have a bunch of tests that all pass when run individual. They even pass when run as a full test suite, EXCEPT when I add in my TestCase ExploreFeedTest
. Now ExploreFeedTest
passes when run by itself and it actually doesn't fail when run in the full test suite as in running python manage.py test
, it causes another test HomeTest
to fail, which passes on it's own and passes when ExploreFeedTest
is commented out from the init.py
under the test
folder. I hear this is an issue with Django not cleaning up data properly? All my TestCase
classes are from django.test.TestCase
, because apparently if you don't use that class Django doesn't teardown the data properly, so I don't really know how to solve this. I'm also running Django 3.2.9, which is supposedly the latest. Anyone have a solution for this?

I was also using factory boy, which doesn't seem to play nice with test suite. Test suite doesn't seem to know how to rollback the DB without getting rid of factory boy generated data.
