In Apache Airflow, when a new DAG file is created in the /dags directory, it doesn't show up immediately in the Airflow UI. There is some delay before the DAG becomes visible and accessible. Why does this happen? How can we make it appear faster? What is the best way to handle this?

I have a refactor job to convert contents in a .jar file into typescript. It is a pretty big codebase with many proprietary dependencies. So all the dependencies also have to be converted to TS. How can I go about this without just brute forcing with claude?

I have a clone of a project that I don't own. I am "customizing" the project by mostly adding files and periodically modifying upstream files. I do my work on feature branches off dev. The purpose of dev is to aggregate my features and changes to the project. I need to periodically "update" dev with upstream/main. This is where I always run into trouble with merge conflicts or wiped out changes. What does this community advise for a git workflow that makes updating to upstream/main less daunting of a task?

For example, I am trying to create a vector where the output would be 1, 2, 4, 8, 16... and so on. I was attempting to use the rep-function, but now I am not even sure if that's the right place to start.

I have a stacked bar report where the x-axis is a month ID, 202503 through 202604, a 13 month sliding window. The stacked bars are different type of allegations (RCSPrimary). My user wants each Month_ID sorted by the number of each allegation, count of allegations. I've added 2 different flavors of SQL to do this, creating a column, SeriesFrequency, that does this essentially, and when I group on that column to sort the Series group, each month ID (x-axis, category) is indeed sorted by number of allegations. , row_number() OVER(PARTITION BY Month_ID order by count(A.Allegation) desc) AS SeriesFrequency But the legend duplicates and the colors for each allegation type in the legend change. I believe I know what is happening. It's because the SeriesFrequency can change for any allegation in any month

I've noticed in my Information Systems course that many people still lack the specific knowledge to program, and don't even understand a new and complex language like Java. We're in our third semester, and even so, we're having a lot of difficulty really understanding what the professors are actually trying to teach. Therefore, I'd like to know, "If you were teaching someone Java from scratch, what would your explanation be for understanding the basics?"

I'm trying to use Lazarus 4.6 on macOS Catalina 10.15.8 on a macBook with an Intel processor. I have Lazarus 4.4 installed and it works. I also have XCode 12.4 installed. I downloaded lazarus-darwin-x86_64-4.6.zip, turned off the quarantine flag, and unpacked it. Both the lazarus.app and startlazarus.app applications have the circle-bar across their icons. Double-clicking either brings up a notice that says: You can't use this version of the the application "lazarus" with this version of macOS. You have macOS 10.15.8. The application requires macOS 15 or later. Poking around in the Info.plist files, I don't see the OS range specified, so I don't know why or how that message comes up. Also, the posting on their forum mentions macOS 10.12, so if that older release is supported, I thought 10.15 would be, too. Any clues?

I recently updated Flutter to version 3.29.2, and since then, I have been experiencing issues when running flutter doctor or pub upgrade. The error message I receive is: flutter doctor Building flutter tool. Running pub upgrade - -. Resolving dependencies .. Got TLS error trying to find package crypto at https://pub.dev.

I want to use puppeteer to generate pdf file by visiting my website. The problem is that while the screenshot method works fine, I can't produce pdf file. This is my code: async generatePdfByWisitingWebsite(user: UserEntity, data: InputGetPdfDto) { const browser = await puppeteer.launch({ headless: true, protocolTimeout: 500000 }); const page = await browser.newPage(); await page.goto('http://localhost:3000/login', { waitUntil: 'networkidle2' }); await page.type('#email', '...'); await page.type('#password', '...'); await page.click('#loginButton'); await page.waitForNavigation({ waitUntil: 'networkidle2' }); await page.goto('http://localhost:3000/app/account', { waitUntil: 'networkidle2' }); await new Promise(function (resolve) { setTimeout(resolve, 2000); }); const content = await page.evaluate(() => document.body.innerHTML); console.log(content); await page.sc

So, I want to convert only the first letter using REGEX and then bypassing function to uppercase it. However Typst return "expected string or content found dictionary" This is the source: #let text="oh this is it" #text.replace(regex("^\w"), m=>upper(m)) and oh, If you have insight on custom function as a callback in Typst I would be happy as I really struggle to find good documentation on it. thaks I tried that code and I expect the first char to be upprcased but didnt work
