I'm not sure what problem you're facing. The Matcher#doTransaction method should never receive a mutableData arguments as null, since it's annotated NonNull. Remember, the doTransaction method works at the parent node of all challenges, e.g. the list of all challenges. It shouldn't be null, but it doesn't have to contain any children.

I think the notion of punishing a company is wrong. A company doesn't have feelings. If a company is broken up for the good of the people, then it should be fine. After all, the company was made to provide services to the people.

I think your getting it wrong. A network is abstract, right? A network refers to connections b/w a group of two or more devices. The Internet is a network itself composed of nested networks and then end-user devices. So, IoT means the network of all things, e.g. the Internet of all things. The phrase "connected to the Internet" infact should be corrected. But the fact is, alternative phrases don't exist. Your phone doesn't connect to the internet, rather it becomes a part of it

HashNode is a pretty good site for stuff related to programming in general. Articles on engineering tend to have a much more formal tone than ones here. HashNode is more of a small community of software devs than a formal wiki or Q/A forum like StackExchange. If you ask a really hard science question here, you have to be really lucky to get an answer. You are free to write scientific articles here related already indirectly to computer science. I think they should get a decent reading. Bottom line: Everything is allowed, no one will stop you. It might not be appreciated though. P.S. I love engineering and science, but this is a community, and I'm trying to talk from its perspective.

That hashexchange thing sounds hilarious.

The factor isn't same by the way. I think going from $30K to $80K should be compared to $350K to $1M

It's amazing to know that most people voting here are on a Linux OS. I believe that the developer should do all development on a GNU/Linux distribution.

I think it is Hypervisor and not Hyperwisor

I think the Hypervisor is being misspelled as Hyperwisor.

How does Google terminate Google play accounts? It terminated my developer account with anyone properly talking to me: just "you violated our terms and we won't be re-opening your account". What can I do? I emailed them back asking for at least a valid reason. The automated message from them says that my account was terminated due to a successful chargeback on my end, probably for registration fees. They say to contact my credit card provider if that was done in error. But I used a debit card to pay. Bottom line: This is really petty on Google's side.
