I am running a Java-based Docker container (eclipse-temurin:21-jdk) inside an EC2 instance using Docker Compose. I understand that by default, Docker containers cannot access the host network unless network_mode: "host" is enabled. However, I noticed something unexpected: When I run curl inside the container to fetch instance metadata from the Instance Metadata Service (IMDS), it works fine: curl http://169.254.169.254/latest/meta-data/iam/security-credentials/ This successfully returns a response....

I want to export my sales data to a CSV file in a rake task. The sales table has roughly 100 Million entries. How can I optimize this code? It seems to slow down the longer it runs. sales = Sales.where(year: 2024) BATCH_SIZE = 10_000 header_names = %w[user_id article_id amount currency date] batch = [] File.open(filepath, 'w') do |file| sales.find_each(batch_size: BATCH_SIZE)do |sale| batch <<...

Now, since this change in Tomcat, I can't write anything with Webdav because the...

I’m new to C programming, and I’m trying to read user input using scanf(). However, when I try to enter a string with spaces, it only captures the first word. It seems like scanf() stops reading after the first space. Why does this happen, and how can I read the full line of input?

My background worked implements boolean for one status which I'd want to read via API. Previously, I have used keyed services, but it does not seem to exist for hosted service.

CREATE DATABASE float_test; USE float_test; CREATE TABLE float_table (float_field FLOAT); INSERT INTO float_table VALUES (21666.66); SELECT * FROM float_table; DROP DATABASE float_test; This outputs 21666.7, despite a 4-bytes float largely being able to store 21666.66 with much more precision (https://www.h-schmidt.net/FloatConverter/IEEE754.html) : enter image description here So what is going on here ? Does MySQL not handle float in a standard way ?

I am senior dev at some company. I have to work on the new version of the software and i am by far the most senior in the team. After setting a monorepo nextjs front and nestjs back (on my boss request) and using a self hosted gitlab for deployment, my boss decided he would prefer we use docker, the problem is that while...

I have very limited knowledge of JavaScript. Trying to script my IoT device with the help of a known LLM, I boiled down my issues to this: let testArray = [3, 1, 2]; print("Does sort exist?", typeof testArray.sort); // Should print "function" returning: Does sort exist? undefined So it looks like Shelly's version of JavaScript (Espruino, according to this) does not have .sort on...

As far as I know (but i'm quite new in this topic) there is a standard way of setting headers in varnish that looks like below set resp.http.X-Custom-Header = "some-value"; But what I really need is a header with dynamic name (or at least part of the name should be dynamic). This dynamic name is based on request or response data. For example I'd...

I’m experiencing an issue with deploying my applications to Elastic Beanstalk using the EB CLI. It has always worked fine in the past, but recently, even though eb deploy completes successfully, the application still runs the old code.
