Hey Everyone,

Long time lurker, first time poster. I wrote a Java program that keeps running out of memory and getting killed by the operating system's (Linux CentOS) Out Of Memory Killer.

First I thought this was a memory leak, but after profiling with Java Flight Recorder and analyzing in Java Mission Control, I don't think it's a memory leak; used heap size remains very low, around 25 MB.

I've tried running the program with several command line parameters, such as -Xmx2g and -Xmx128m to increase and decrease the max heap size respectively, thinking this might either avoid OOM killing or increase frequency of garbage collecting. Machine has 1gb of RAM.

I'm compiling and running with OpenJDK 17. Not getting exceptions or errors when program runs.

Any feedback would be much appreciated. I'd be happy to give more details if helpful.

In Mac using Activity Monitor app it shows all the Java Apps but i don't know witch java app is using x amount of ram, i would have to inspect each of those apps.

Can i in terminal list all the Java app with actual name of that instance running and showing how much ram they are using?

Hi! My name is Vandolf. I am very excited to share with you, and with the entire Android community, what I have been putting my heart and soul into consistently for the past 3 years. My love and gratitude for Android development has kept me motivated to work on this project non-stop. This is my way of giving back to the Android community because this career path has enabled me to break the cycle of poverty in my family lineage. I am not doing this for fame or money. I simply want to give back ❤️

So...

Let's solve the Contacts Provider, together! 🤝

The Contacts Provider is huge, complex, and full of rules and behaviors that we have no control over and may differ with every flavor and version of Android. With this in mind, I have built and documented a large set of APIs packaged into a single cohesive library.

GitHub project: https://github.com/vestrel00/contacts-android

Showcasing usage of the Contacts, Reborn library. Not all features are shown.

>I initially made a different video for this post out of excitement but I figured this one is more appropriate 😄.

Features!

• ✅ Harness the full potential of the Contacts Provider without having to deal with ContentProvider operations and cursors.
• ✅ All of the tools you need to create your own full-fleged Contacts app.
• ✅ Fully interoptible with Java. It is Kotlin-first and Java-second (with love and care).
• ✅ Barriers to entry is ZERO. Whether you have yet to write your first line of code, or you are just getting started with Android development, or you've been at it for over a decade, this library will guide you on how to use it.
• ✅ Extensions (optional) for multi-threading and permissions with Kotlin Coroutines.
• ✅ Create, Read, Update, and Delete (CRUD) operations for all columns in all tables within the Contacts Provider database; Contacts, RawContacts, Data, Groups, Profile, and AggregationExceptions.
• ✅ Provides a powerful, type-safe query DSL that utilizes the magic of Kotlin.
• ✅ Built with optimization in mind; include only desired fields in read and write operations and supports pagination (sort/orderBy, offset, limit) and cancellations.
• ✅ Fully documented entities that model all common data kinds; *

I'm having trouble reasoning about the recursion process here. The sum of the die can either be: 3,4,5,6,7,8, or 9. There is one way to get 3 or 9; three ways to get 4 or 8; six ways to get 5 or 7; seven ways to get 6. The problem I'm facing is twofold: I'm not quite sure what the recursive function is supposed to return and also, where in the process to call the recursive function.

Here is my pastebin: https://pastebin.com/4mz4qHWb

Hello everbody!I'm facing this new issue where my HDD is constantly writing, and when I start iotop, it shows the following process (sometimes even double!):

29587 be/4 100 0.00 B/s 26.57 M/s 0.00 % 24.53 % java -Xmx256M -DfromWrapper -XX:TieredStopAtLevel=1 -noverify -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/config/logs -Dsp~ng.output.ansi.enabled=ALWAYS -jar /app/nzbhydra2/bin/lib/core-4.0.1-exec.jar --nobrowser --datafolder /config [MVStore backgro]

I'm running NZBHydra2 in a docker container on my Synology NAS. I just updated the image AFTER hearing my NAS constantly writing and the problem persists. I can't really tell since when this problem exists because I have my NAS in another room and don't hear it when I'm not in the room.

Any help is highly appreciated!

Edit: here's a picture from iotop

Hello, I've recently been trying to make an alternative way to inject into a custom launcher
(cheatsum and all that good stuff so I cannot throw in a hacked client and expect it to run)
since they've encrypted the Minecraft's jar file
(it's not a .jar anymore it's .bin*)*
and I don't have enough knowledge to crack it. Is there a way to pull the bytecode out of a running java process I couldn't find much information elsewhere maybe someone here has knowledge?

+ There is actually the code to decrypt the binaries but it's located really deep in an obfuscated jar from what I've heard. Some people have made clients able to logon the server with MCP 1.8.9 by manipulating packets Minecraft sends but I have absolutely no idea of how to find the packets and replicate them alongside the sessionID stuff

In case you are asking me why I need the jar file, well I need to map the transformers to actually work with the right class names ( the version file is obfuscated so basically its architecture is very VERY different from normal minecraft)

The said custom launcher is called Sonoyuncu (It's for a custom server that can only be entered from a certain client)

And if you actually read through all of this all I can say is well done and thanks for your guys' help.

p.s admins should add a flair for reverse-engineering related topics.

In his video at https://www.youtube.com/watch?v=GctwVOSpAHU&t=178s, Xisuma mentioned that he reconverted all the world downloads with a "better conversion process" that had less glitches and stuff. Does anyone know the name of the software he used?

I was about to play minecraft this afternoon when I went into the minecraft launcher, and it asked me to sign in, but whenever i click "sign in with microsoft" (I transfered my account) it gives me the red thing saying "Something went wrong in the login process" in the top right corner

Let me explain myself: I'm not trying to be elitist here.

With that being said, most of the communities I tried to participate ends up swamped with people asking very beginner questions, and the feeling I have is that there's not a place (zulip, matrix, slack, etc) where there are real experienced java guys to exchange ideas, knowledge, etc.

Does anybody know any?

Hi everyone, I've been running a small survival community since mid-2019. We are doing our first ever reset since then for the 1.18 update. I think it would be a good opportunity to have some new members.

We are a very welcoming community and family-friendly! For transparency, here are some features that our server has so that you can effectively decide if it is a kind of server you would want to join:

• Java and Bedrock are both compatible
• Build in towns, in markets, or out in the wild
• A simple registration system on first-join to deter low-effort trolls and griefers
• Ability to protect builds if you desire
• Easy rollbacks from staff if griefing occurs
• Keep inventory and xp upon death
• The usual ability to warp to spawn or set homes
• A community culture that tries to emulate personal growth and behavior more akin to how people act in real-life interactions rather than Twitter/Reddit toxicity
• A fun feature where different players get to take turns each week in the roles of nerfed versions of staff ranks

The relaunch is planned for tonight. Send me a message if you would like to join us! You are welcome to ask, even if you read this later on!

I contacted SciPy about it. Pretty much what I found is that if you take recursive deviation of adjacent points with a static delta x you then get a value that iterates over and over. I then developed a formula to find the coefficient of the highest monomial in the polynomial. You can then subtract out the correlating monomial values and be left with the successive parts of the polynomial. After doing this process recursively you can then solve for all the coefficients in the polynomial. What should I do with this?

Here's a video of the vertical algorithm.

Here's the math examples

Here's the current code. I'll update the README.md file as soon as I can.

I redid the implementation in college in Java it's a lot better than what I did in python and actually uses recursion.

https://github.com/jmoseman01/ssrsteomjava

I reimplemented my java implementation in python. It actually has a README.md

https://github.com/jmoseman01/modernSsrsteomPythonImp

Here was my first go at it in python. I will make a better implementation of this with more coherent variable names. Sorry for the lack of polish this was just a high school science fair project with little accommodation or guidance.

This is my Jupyter Notebook explaining how I developed this polynomial interpolation algorithm.

I have been able to log into my account perfectly fine today with no issues but all of a sudden tonight it keeps popping up with this:

no clue why or what I did but if anyone could help me it would be appreciated (this is also the old launcher and not the new one)

Something went wrong in the login process. If the problem persists, check your internet connection.

This is the alert that shows me when I try to log in with a microsoft account, on the 27th of this month I could still play without any problem, on the 29th I play for a while but when I open the launcher it keeps in an infinite loop to log in, so I decide to reinstall the launcher and surprise the above mentioned alert. I also reinstalled Windows thinking it was a virus causing the problem, but the problem persists even with a clean Windows installation. On the page allows me to log in without any problem as in another launcher (LunarClient).

> It seems to be a bug in the launcher and the solution I found temporarily is to use another launcher.

I purchased Minecraft this year, January 6th and I haven't had any issues since except for not too long ago. I created my minecraft account with a microsoft account but I didn't migrate. Now whenever I try doing microsoft login it says "Something went wrong with the login process". I've seen another person have the same issue but I have mac and they had windows. I tried logging in with mojang account but then it would only let me play the demo. (solved)

Hello! I have recently noticed that I cannot log into my Minecraft account through Microsoft, A few days earlier I had been able to log in and play and now I cannot, It will just say "Something went wrong with the login process" once I click on Microsoft Login. Does anyone know a fix for this? I have tried : redownloading, changing my .minecraft folder to a new one, Logging in and out of my Microsoft Account. If you know a fix, please respond. Thank you
