[Enthuware Java Certification OCA OCP @Enthuware]

An OCP Java 17 1Z0-829 certification exam taker reported that they got 5-7 questions (out of 50) on Serialization, which means the exam designers consider it to be a very important component of the Java language. When did you use Java serialization last?

@lukaseder If the method is not well thought out, using the suggested name will only cause confusion down the line and if the method is well thought out, you won't need any help naming it.

@deedydas Two opposite pulls - India has a huge number of kids to educate and one size doesn't fit all. There is space for all sorts of smarts - having students who can crack JEE style questions in the country is as important as having students who can think out of the box.

@Enthuware Python was created as a joke. Many took it seriously :)

@ShashwatGoel7 @iiit_hyderabad Tag @cfs_telangana please. They are the competent authority for food safety in Telangana.

@ShashwatGoel7 @iiit_hyderabad Kudos to you for reporting this. Sincerely hope that you don't face any repercussions from the college admin.

[Hanumant Deshmukh @hanudesh]

@cfs_telangana @fssaiindia Please check. This is serious.

Students at @iiit_hyderabad, supposed to be one of the top engineering colleges in the country, are in an ongoing health crisis caused due to appalling mismanagement and negligence going on since well over a year. 🧵👇on mass typhoid breakouts, food poisoning, underreporting..

@vibhurishi Interesting. Gatekeeping is polymorphic :)

@brunoborges I am sure Gradle will be among the top few😀

@sur3shg @imsofresh_x @shanselman Although having power tools is not the same as having the expertise to use them, I would still want to have them rather than not.
async await is a great tool but not as an alternative to v threads. Java will have it by Java 33!

@rixlabs Wrong. Mgmt is a necessary evil. If there is no PM and if the team is "working well", someone on the team is being shortchanged.

@simas_ch Java dropped the ball on UI. @dart_lang @FlutterDev is a much better option. It is doing the same to UI what Java did to server side.

9. Exception handling
10. Libraries

What else?

[Hanumant Deshmukh @hanudesh]

10 things a polyglot programmer needs to know when switching to a new language:
1. Typing system - static, dynamic, fixed
2. Available data types - primitives and reference
3. Parameter passing - by value, by reference, both
4. Arrays - jagged or matrix like

[Hanumant Deshmukh @hanudesh]

5. Null handling
6. Memory mgmt - automatic or manual
7. Higher order functions
8. Multitasking - threads or async

@kritipraks Why not? Life is short.

@tagir_valeev A large number of IT books are written by non-native-English speakers. These are ghost authored by an additional native English speaking "editor". Do they qualify for the "100% natural" tag?

[Hanumant Deshmukh @hanudesh]

@trisha_gee @nipafx That' true. Many don't use java.time because dates and timestamps coming from DB extend https://t.co/km7YYOb0Mb. They have no need to convert them into LocalDate/Time.
