Yesterday we had to do a demo for the client. Burned the whole day trying to fake, mock, and prettify things. And boi was it a crunch!

I don't remember sweating this much while working mentally.

After EOD, my shirt was literally reeking, my butt was sore, and I barely had energy to walk to the bed.

I hope you can compensate for that by leaving early at the next day.

I can't imagine what kind of client demo would result in a sore arse but hopefully they pay well.

@donkulator maybe the 3 billion devices that run java

@Lensflare Don't forget about your sim card

@BordedDev it runs java? Noooooooooo!

@Lensflare Yup sim cards run java, afaik without the JVM. https://en.wikipedia.org/wiki/...

@chatgpt tell me about java card and programming sim cards

@BordedDev
Java Card is a technology that allows Java applications to run on smart cards and other similar small memory devices, such as SIM cards. Java Card provides a secure environment for applications and is widely used in secure elements like SIM cards for mobile phones.

Programming SIM cards using Java Card involves developing applications that can run on the card's secure element. This can include tasks such as handling authentication, processing secure transactions, and managing data securely.

Some common tasks in programming SIM cards with Java Card include:

1. Creating and loading applets: Java Card applications are known as "applets" and must be developed according to Java Card specifications. These applets can then be loaded onto the SIM card to provide various functionalities.

2. Secure data handling: Java Card provides secure APIs for handling sensitive data, such as user authentication information and encryption keys. Programmers need to ensure that data is securely

stored and processed within the SIM card.

3. Communication with external systems: Java Card applications on SIM cards often need to communicate with external systems, such as mobile networks or other secure elements. This involves implementing communication protocols and ensuring secure data transmission.

Overall, programming SIM cards using Java Card requires a thorough understanding of Java Card technology, secure programming practices, and the specific requirements of the device on which the applications will run.
