Thanks, some of them are quite handy. I'd suggest you might want to add CyberChef.

From the description of CyberChef:
Some examples usages:

• Convert data from a hexdump, then decompress
• Decrypt and disassemble shellcode
• Perform AES decryption, extracting the IV from the beginning of the cipher stream

Source is available here and it can also be run locally: https://github.com/gchq/CyberChef

I like the way they answer the question...:)

---------------
Can I download a transfer that expired?
There's no way to recover a transfer that is no longer available on our servers. If you see any of our illustrations like the one below:

It means that when the transfer hits the expiry date, it gets deleted from our servers. Deleted, foetsjie, gone with the wind. Gone really means scrubbed completely from our servers.

We promise senders a certain period of availability when they use our service, and we need to keep our promise and delete the transfers after that period. Besides keeping a promise, we also need the server room, for new uploads.

You were probably hoping we have a hidden stash of expired files somewhere to retrieve those valuable files. We wish. But we don't.

The only option -if you're the recipient of these files- is to contact the sender and ask them to send you the transfer again.

Bear in mind, with a Plus account, you can set the expiry date of your transfers to stay active for as little or however long you like. Want your transfer to never expire? Say no more, WeTransfer Plus will allow you to do just that!

For lazy guys bunch of online tool to run code

Support python, C++, ASM, PHP, C# NodeJs and a lot more.

Amazon Cloud9 is quite similar:
But to dismiss this as for being for lazy programmers is a serious misread of what is happening.

Just like Windows is becoming rapidly a service model and not a product anymore. So to the IDE and programming environment or editors is also becoming a service model and moving away from the product model.

The good old days of being free to own your software and tools is coming to an end and the servicization of the computing world will continue for quite a while as its a more profitable business model. There will only be niche tools and a niche audience remaining on the old models more than likely.
