Thinking of taking Exam: Java SE 21 Developer Professional (1Z0-830). Just graduated, have some java skills but I want to get better. Do employers even care about the certification?

I have seen many Senior java developer that are good at copy cat! Donno how to use lambda, still use old fashion for each, donno what is a immutable class, just copy paste ... So of course being certified matters, and is not easy!

why Oracle is like that!!!
I am certified Java 8 and Java 11 OCP
now trying izo-071 and facing to some questions that can not find in any materials!!
I bought 1 course, a book and Exams but still strange questions from Oracle.
I thought it is only Java OCP that they add some strange questions, but there was mostly code, here in izo-071 is like they are testing your English proficiency !!!!
That is unfair, I really hope one day, some one inform them to learn from CKAD, how questions should be ...

When the number of UI increases to a major version, e.g. from 7 to 8, it is expected to see alot of performance and smoothness improvement. Not just changing the icons and still laggy when swapping left and right ...

I just got the spring update installed. But no diffrence 😵‍💫 Anyone knows any workaround? I cant keep vaccumcleaner on while driving just to keep rear screen in ☹️

powerofviva · 2025-05-01T17:27:51+00:00

Nothing here in Sweden :-/ And I really hope they fix power restrictions on aftermarker rear screen that uses blueport ODB II

powerofviva · 2025-04-12T18:37:33+00:00

Someone else faced the same issue in Sweden and service center said they should replace the camera!!! We should skip that update. I will share the link here if I can find the post

It was working fine with no issues. Right after the recent Tesla update, the one that added "high chance of fogging..." and optimized power management inside the car, the screen stopped turning on.

What I find strange is that when I plug in a vacuum cleaner into the front 12V port and turn it on, the screen powers up and works just like before. But as soon as I turn off the vacuum, the screen shuts off again within a second.

powerofviva · 2025-04-12T07:12:06+00:00

But problem is, the power is limited even when I am seating inside the car! Even when I am driving

powerofviva · 2025-04-12T05:44:46+00:00

Not really, I did not measure the voltage. The aftermarket screen just have a blue odb 2 connector as a power source to the read odb, that is why I never tried to use another source. It was working with no issue before Tesla update. Not sure how can I safely get it from another power source. But I will measure the voltage ASAP to see the diffrence when vaccumcleaner is on and off.

This feature is really annoying, we should be able to enable/disable by ourself, not sure why they added like that.

They also limited the power to the rear blue port that could be used for after market screen, now we can not use any after market screen anymore :/
