I said "Let's use C for this year's hashcode challange" as a joke.

Guess who's writing C code tomorrow

When I first began with Python I really missed the static typed checking from Java, I barely know anything about a returned object from a method and have to read the API extensively for every new library.

After a while I finally understand why Python is so powerful, the combination of dynamic typed language and rich default methods make the language unbeatable for your productivity.

While Java's Object only has toString(), hashCode(), equals() or clone(), Python's basic Class has every fucking method for every scenario I could ever image. No wonder that libraries like numpy or pandas work so well and fluidly.

Today I was reminded of a valuable lesson... Never compare strings with == in java... Just spent like 30 minutes wondering why my string that I was getting from a browser parameter wasn't equalling the value I was checking for...

Apparently when I get a value from a requestParameter in spring, despite being a string it doesn't get a hashCode for some reason, or at least it got a hashcode of 0, so my strings weren't comparing because of that...

Does anyone have a true measure to recruit freshly graduated? yesterday I had a technical interview with a candidate, the problem is he didn't know even the basic of coding in Java, like String equality and hashcode, he also didn't have a solid understanding of basic design pattern. But what made me want to give him a chance is that he seemed highly motivated and eager to learn. So I don't know what to do guys?

Need a team name for Google Hashcode, please suggest something bad.

I'm running into an issue with code coverage... I ran the analysis and it's penalizing unused getter, setters, equals, hashcode.

And the thing is I need those getters so GSON will serialize the fields...

How do you make coverage always > 80%?

Based on current analysis, I only get 60.

The other day was reading someone else's shitty code which had taken an object into a set without implementing the hashcode and the equals, cursed the developer and fixed that and informed the QA about their lackadaisical attitude. Later on that fix broke some other functionality on live and now the QA team gives me the stares. Feeling like birdman...

Yeah so I'm heading into Google hashcode without a single idea what to do, like what's a 0 based coordinate

So I'm working on an assignment for my Computer Science class, and we have to basically compute strings into hash values and then modulo it by 1 million and put it into the hash table. But the value keeps overflowing and turning into negative values, anyone know how I can calculate the key?

(BTW, the hashcode is the same code that is calculated by the .hashCode function in Java)

Struggled whole day to remove duplicate objects from a list in java. Those objects (of a custom class) contain a unique id, the remaining properties can be identical across list items.
Wondered why hashset.add() always returns true and thus duplicates are still inserted.
Little did I forget about things like equals() and hashCode() 🤦

I had written a feature that stored some data for all methods in a code base. And it worked in 99.9% of all cases, but for some projects, somehow there were errors in the logs that I couldn't understand.
After hours of debugging, it turned out that I inserted the method objects into a map, and the (existing) base class for these objects used the character offsets for the method's start & end in the hashCode() implementation. This meant that in the (extremely rare) case of two methods in two files with the exact same start and end offsets, inserting them into a map would overwrite the previous value.
Once uncovered, this bug was trivial to fix ;)

Who wants to collab with me for hashcode ?

I don't mind working with c , python , c++ , js , Java and similar languages I guess.

(I don't like Google but a competition is a competition)

We have a huge domain model in Java and something is really fucked up with our equals/hashcode implementations and know body can track it down.

I have suggested Lombok/Groovy several times but they didn't listen.

Anyways it is so fucked up, that map.contains(foo) returns false, although it is part of the map.

So we wrote something like this:

for (Entity e: map.keyset) {
if (foo.equals(e) {
return true;
}
}

New year, new Google HashCode!!!

I need a new stupid name for my team, last year "SicroMoft" by @Fast-Nop was great, but this time I need something even better (or worse)

Also, who else is participating?
