Input sanitization in mobile applications

User input sanitization is very important for multiple reasons in any kind of application design. It is to ensure security, and meaningful input. There could be unwanted consequences if this was not taken care of, as we see in examples of some large corporates accounts getting hacked for credit card data of its consumers. This could be achieved in multiple ways from checkboxes, to regular expressions, depending on where it is to be set up.

    The security aspect for the need of cleaning of input can be further divided into multiple realms. Mainly, its for the security of the company networks, so that it's safe from injection attacks that is achieved by taking only input that is necessary; also, it helps the end user, as the safety of information of any corporate (unlike Sony in early 2010s) can safeguard their personal and payment information.

    Secondly, input sanitization helps in increasing efficiency of the system, and helps against any crashes that might occur in case of e.g. runtime errors. The increase in efficacy can be achieved through use of Client-side and/or server-side verification which also helps save bandwidth of the networks being used.

    Thus, input sanitization and verification can be a great help in saving resources and important information, plus help against crashes in mobile applications. Not doing this would make the mobile application quite cumbersome for both corporate and the end user. Applications are meant to achieve a specific purpose, which can surely benefit from input sanitization.

New pricing model of ChatGPT Pro, and its effect.

As someone who has been using the OpenAI API to power my chatbot, I was excited to hear about the release of ChatGPT Pro. The new model promised to be even more powerful and accurate than the previous version, and I couldn't wait to try it out. But when I looked into the pricing for ChatGPT Pro, I have to admit, I was a bit disappointed. The cost to access the new model was significantly higher than the previous version, and I wasn't sure if it was worth the investment. On one hand, I could see the value in using the more advanced model. ChatGPT Pro is reportedly able to handle more complex and nuanced conversations, and the improved accuracy could help my chatbot better understand and respond to users. On the other hand, I also had to consider the cost. As a small business owner, I have a limited budget for my chatbot, and the increased cost of ChatGPT Pro could put a strain on that budget. In the end, I decided to give ChatGPT Pro a try. I found the improvement in the...

Driverless Cars (A perspective)

Driverless cars have come in vogue since Elon Musk came to helm at Tesla about a decade ago. He brought with him the knowledge and ambition of the information and communication technology industry into an old and conventional industry such as car manufacturing. Since the Tesla's growth through these years, driverless technology has taken everyone by storm and multiple people from George Hotz (a jailbreaker once) to corporates such as Ford, at the forefront of achieving  this once difficult dream. The advantages though are ease of access, and lesser possible collisions and disadvantages being humongous costs of transition, and takes away the thrill/ driver jobs. Source:  indiatimes.in     First, discussing the pros of this new technology, companies like ZooX (my cousin works here) and Tesla have come a long way in designing cars, which are mostly autonomous and don't need a regular access to servers for basic navigation through the present road infrastructure. This he...
