Why there are so many drops? It turns out that in graphite we have a configure # Softly limits the number of whisperRead More →

Have you ever thought of backing up your icloud photos to your own disk? Well, i haven’t found tools to do this job yet. I spent few hours to see how ICloud photos works via web interfaces.

We need to make sure that these lines below should be always run at the end: //await har.stop(); //if you collect har file await browser.close(); //process.exit(0);Read More →
When you run puppeteer, you can either to run it in headless mode or normal mode, headless is a little bit faster. Which one you should use? In my case , i select them for a few reason: Normal mode: i need to load a chrome extension to do fix the NTLM authentication Headless mode: i use it since, we have a site using certificate authentication, it has a popup. i couldn’t find a way to get rid of that certificate menu. Running in headless mode force Chrome to not authenticate with certificate.Read More →
