Sad & bad dev workflow

The current state of things, by example

Converting JSON to CSV be like…

  • Watching 5+ ads and getting distracted by flashy websites.
  • Getting tracked by 3rd-party services.
  • Landing on a different website every other month.
  • Leaking sensitive customers' data to trackers and browser extensions.
  • Feeding a foreign AI model with secret tokens and env vars.
  • EU bonus: eventually getting arrested due to GDPR violations.

Operating Offline

Hey, it's Wiktor 👋. I built and now happily maintain the SafeUtils app for two reasons:

1. It felt like I'm about to go to jail every time I pasted my data on the Internet.
2. It was WAY too many bookmarks, and they didn't even cover half of my needs.

I decided to equip other developers with a missing solution to their everyday operations.

MacOS: SafeUtils is damaged and can't be opened.

When an application gets downloaded from any source other than those that Apple seems suited, the application gets an extended attribute

This triggers the message:

"AppName is damaged and can't be opened. You should move it to the Bin."

Remove the attribute and you can launch the application.

To do this, open a console and type:

$ xattr -c /Applications/

Source: XYZ Is Damaged and Can’t Be Opened

Microsoft: Windows protected your PC

If you get the following prompt on Microsoft Windows:

Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.
