With specialized tracks like Coding Brushup for Java, Coding Brushup for Python, and React JS, this platform is revolutionizing the way people prepare for real-world tech roles.

Why Traditional Learning Isn’t Enough

Most developers start their journey with structured courses—college degrees, online tutorials, or bootcamps. These provide foundational knowledge, but often lack:

Hands-on coding practice

Real-world problem scenarios

Industry-relevant tools and workflows

Performance-based feedback

Without these, even well-educated developers may feel lost during interviews or job onboarding.

Coding Brushup was designed to fill that void.

What Is Coding Brushup?

Coding Brushup is a practice-driven learning platform tailored for developers who want to refresh, reinforce, and refine their coding abilities. It blends theoretical understanding with hands-on challenges, allowing users to build real coding confidence—quickly and efficiently.

Today I started redoing my Russian notebook, I started with the alphabet, and I'm going to practice cursive writing more, I find it very difficult to do in Russian.📓

In addition, I'm almost finishing my Git course, which is one of the modules of my Java course, it's interesting. 🧑‍💻

I'm feeling better, I have some clients and I'm selling well (I have a 3D printing store), I'm happy that things are getting better.📚

✰ wonwoo x gn. reader ; fluff ; 0.6k

Wonwoo's blue full-sleeved shirt was curry-stain free and worn the proper way. He smells of freshly washed linen and breath mints. The weather is perfect, warm rays of sunshine spreading across a cloudless sky (he carried an umbrella nonetheless).

So far so good. Grade B, even.

Today is the day Wonwoo would try and catch the seat next to you in the Environmental Technology elective you both took. Maybe strike a colloquy with you on environmental toxicology. Maybe even exchange numbers.

“You’ve been saying the same thing for the past three weeks.”

“But-” Wonwoo stops, frowning at the notification on his phone. Soonyoung glances over his shoulder to take a look. The former sighs. The latter doesn’t bother to conceal his laugh.

Wonwoo had run a lot of scenarios through his head, finding appropriate solutions for each case. Nothing however would have prepared him for the class getting cancelled today.

“On the brighter side, you can practice your pick up lines on yourself for another day.” Soonyoung clears his throat to match Wonwoo's voice, “are you a data type? because you float inside my mind.”

Soonyoung sidesteps, avoiding the jab coming his way. He backpedals away, mouthing better luck next time as he leaves for his next class before the “Shut up.” leaves Wonwoo's lips.

And that’s how he ends up in the library, trying to finish his assignment for the OOP using Java bridge course. The key word is trying; there’s only so much freecodecamp.org can help with. He twirls his pencil around his thumb. Today was a failure. Maybe he should quit this and visit that new boba place instead.

“Hey, Wonwoo.”

The pencil falls from his hand and onto the floor. Wonwoo looks up to face you. Milliseconds pass by as he digests the fact that you did, indeed, call him.

He likes the sound of his name on your lips.

You pick his pencil up for him, a smile adorning your face as you continue, "I'm-

-(name)”, fuck, what happened to his lower register? “I've seen you around. We share the environmental technology class.”

It all comes out at a pace too fast for his liking, but you nod along. Wonwoo takes his pencil from your outstretched hand, mumbling thanks and trying not to hyperfixate on how his fingers would've brushed yours had he moved them a little closer. Cerise colours his ears at the thought.

You glance at the material strewn across the table, recognition flashing across your face. "I took this course last sem." Your eyes shift to his laptop's screen, which currently flashes a runtime error.

Of all times, why now?

He follows your gaze, feeling sheepish. "Well, this course is not for the weak."

You snort in agreement. "So, want some help debugging?"

"Oh please."

Wonwoo knew he should be paying attention to what you were doing but trying not to hyperfixate is easier said than done. '(name) pulled a chair right next to you to help you', chanted a little voice in the back of his head. From the spark in your eyes and the furrow of your eyebrows to the shade of your currently pursed lips, he couldn't help but notice it all.

This is nice.

"I'm done."

Wonwoo blinks. Already? He looks at the screen and then at you in awe. "That was really fast. Thank you."

Your smile widens. You move your chair and sling your bag over your shoulder, getting ready to leave. "Let me know if you need help with anything else."

It was now or never.

"Are you free for a boba run? it's on me."

One second. Two. Three. He shouldn't have-

-sure. Should we check out the new place downtown?"

"Yes." Yes, anything you say. He stuffs his bag with his books.

Maybe, today deserves a solid grade A.

My 5 Year Old Forever World!

This is just a general infodump post about my bedrock world, posts going into more specific locations and builds will follow...

the top image is the center of my area & main base, its... a unique build. heres a sky view of the land + a (slightly outdated) map (orientation marked 4 convenience)

Bulleted info!

my singleplayer world was originally created on 4/20/20 in version 1.15 on my switch, the current file size is 801.1mb, and the seed is 285279141 (i dont actually remember if i entered a seed or not, it mightve been something dumb like dragonheartshipping4lyfe or iheartirisxbenga, bcuz i was obsessed w them at the time HDHDGD). i am currently at 10009 in-game days, and my account playtime is 135 days and 12 hours (3200+ hours). aside from my test world and a couple copies it is the only world i play on bedrock.

i play on survival + normal difficulty and have cheats enabled, so on bedrock that sadly means no achievements. cheats i play with/have played with are keepinventory, teleport, use of barrier blocks, wandering trader spawns off, fire tick off, and creative/spectator in place of free-cam. before spectator was added i used the program amulet to serve its purpose. i have yet to see credits, get elytra, shulker boxes, or a beacon. i have also used online tools like chunkbase for locating biomes/structures, and amulet to trim my world.

sometimes i plan builds in a creative test world and copies of my survival world. i know this kind of thing can seem pointless, but i just dont get the same sense of satisfaction just building in a creative world. heres what my test world looks like!

my "build style" is over-detailed and inconsistent! i understand not many people enjoy that, but i do, i think its really fun! building whatever i want where ever i want with no regard to the surrounding builds was a staple of my world from the very beginning. it takes a lot of the stress off of just simply playing a video game! this is also a good time to mention that half my base is located underground, so theres a lot not visible in the overhead view! also also, disclaimer that some builds in my world are not of my own design (they are directly copied) or take inspiration from others! i usually look to google images, hermitcraft, and fellow tumblr users for insp.

i save back ups frequently, to my internal hard drive, usb sticks, and my google accounts. ive lost a couple minecraft worlds over the years and do NOT plan on losing this one.

Some Background Info(Dump)!

so my world was originally started on my switch. i actually bought the game on a whim the day before i started it cuz i could (stimulus money). and having not played minecraft regularly at all for a few years, i was excited to get back into it, and being able to lay down while playing. that was a pretty big justification for getting bedrock while already owning java gdgffj.

but of course, that inevitable 2 week minecraft curse that seems to haunt the fandom came for me too. though, for me, the curse tends to crop up at the point im meant to enter the nether. this is the fate many of my old survival worlds had fallen victim to, being abandoned as soon as that portal gets lit, it was like, tradition for me. i could never stay dedicated to my worlds because the monsters, and dying in the game, scared me. that, and being overwhelmed by building. for some reason, i always thought building in the game was a lot harder than it really is. i think i just didnt have the practice, or confidence. these things are why ive had long minecraft droughts, despite really enjoying the game.

so i took a couple months break, believing this to be another case of a neglected world. but the thing that actually inspired to return was hermitcraft. i saw what they did, what they built and what they accomplished, and thought to myself, why couldnt i try harder to be like them? so eventually i returned to my most recent world, i didnt make a new one, and start over, as most people in this same situation do. i continued from where i left off, and, allowed myself to use keepinventory for the first time.

...that is until, after 9 months of owning bedrock, my switch decided to lock me out of the game. less than a year in, the data generated in my world, through natural intended gameplay (exploring WITHOUT the use of online biome and structure finding tools), had exceeded the switchs apparent limits. i know i had free space on AT LEAST the sd card, and yet it refused to let me keep playing, saying to, and i quote, "delete some stuff" so i could play again. aside from a test world that had to have been less than a megabyte in size, i didnt have any other "stuff" to delete to free up room. i thought this was the end of my beloved world until i did some research. buying a realm, copying my world to that realm, and then buying the windows version of bedrock on my laptop and saving the world to it from the realm was the one way to get my save off my switch without hacking it. so i ended up not only purchasing a useless realm, but an entirely new copy of the game just to continue playing on this one world. that probably gives you an idea of how dedicated i am and have been to it, lmao. i have played it pretty regularly ever since.

its so funny to me how what i thought at the time was just another "2 week" throw-away world became something so much more to me. ive never played this game for so long and so consistently, ive never gotten so much done in it, not even in old creative worlds. its really amusing how early builds like my starter house look exactly like all my other builds from my much older java worlds, "build style"-wise, compared to how i do it now.

so, as someone whos been so fiercely dedicated to the same world for half a decade, i just wanna express my love for the forever world trend thats going on right now. thats what inspired me to wanna post about my personal minecraft experience more. i rarely ever do, and thats because.. well, idk. ive become very passive with talking about myself or my interests lately. i guess im also afraid of being judged, because im gonna be real here, the minecraft community is deeply and obnoxiously obsessed with how people play the game, and what the "right" and "wrong" ways to do things in the game are. it really, really gets on my nerves. its one of those things where id prefer to just not get involved. so ive just kept stuff about my play-through to myself this whole time. but the mindset behind the forever world concept going around right now has given me some confidence!

so yeah!! i'll be trying to post more about my time with the game from now on! 🩷

[ms-demeanor]

(remaking the post because you can't edit polls and i gave the wrong options)

Alright I'm registering for classes and someone needs to talk me out of doing stupid shit but I'm unsure of what shit is stupidest.

Winter term:

I just finished an 8-week photo class that ended up being a huge investment in time just to go and shoot. However that was introductory photography and there is a 6-week intermediate photography class over winter term. I am signed up for photography. (Elective option for AA in Visual Arts)

There is also a 6-week introductory python course over winter term that I am signed up for and will be taking. I'm solid on that one, as long as I pass my C# class this term I'm going to be taking Python for 6 weeks at the beginning of the year.

Spring term:

College Chemistry Saturday class. 7am to 12pm for sixteen weeks. Lab and lecture; this school doesn't offer any chem classes that are after standard 9-5 hours during the regular week or that can be taken even partially online. Pretty sure I'm going to be stuck with this one and am configuring the rest of my schedule around being *less* miserable because of this class.

Survey of Western Art - Online, seems like a gimme. Does have a textbook but not one that I'm going to pay for. (Required for AA in Visual Arts)

2-Dimensional Design - Online, seems fun and like a gimme, Free/No textbook. (Required for AA in Visual Arts)

Object-Oriented Programming - Online, seems difficult, expensive textbook. Will probably be very necessary if I end up going down a more CS/tech path. Probably going to force myself to take this class.

Java Programming - Online, seems not unapproachable, expensive textbook. I don't particularly wanna but my school offers really limited options for computer science and I want to get what I can out of it before I go somewhere else.

Rationale for these weird combinations:

I'm applying as a nursing student at three schools and a biochem student at one of those schools (nutrition programs are apparently only for first-time students; 2nd Bachelor's applications are a lot more limited. I could apply to major in Francophone Studies at one of the schools though). Supposing I get accepted, these classes certainly won't hurt my status at any school that accepts me and the chemistry class is going to be really really necessary. This is the "i give a fuck about nutrition science and also directly helping people" path and if I go this way I'm interested in NP programs down the line. LOTS more school of the serious "I can't work and do this kind of school at the same time" variety.

If I *don't* get accepted to the programs I'm applying to, I'm going to go to a different community college and start working on a couple of AS degrees in computer junk (network admin and security management, computer and networking technology) and get some computer junk certs. I don't think I want/need a BS in compute science, this is the "practical" route of "I could finish this stuff pretty easily and continue working in a field where I have a lot of connections and familiarity with the industry but I am indifferent about a lot of it (pretty passionate about security and accessibility tho). Also allows me to keep working while I just churn school in the background, and all of the computer classes are transferable between the two schools.

Art classes: I think having multiple degrees is funney. I am currently 5 classes away from an AA in visual arts, at the end of this term I will be 4 classes away; if I take all the classes here and can take an elective over the summer I'll have a degree in visual arts. (There is a reasonable possibility that I'll continue taking bullshit classes behind the scenes to get silly degrees regardless of what happens otherwise)

Pretty sure the sensible thing is to drop *at least* photography and survey of western art and also possibly Java and 2D design. I'm somewhat concerned that if my spring term is just Saturday chem and object oriented programming I will start biting things.

So:

[birdofdawning]

Helena leans over to change the radio station. "Honestly, I would have hoped that the glib pleastries of Masters of Ceremonies would have improved since my time, but it appears that this is not the case. I'm sure I heard half those inane blatherings at the Pavillion in the '90s and they were old hat then."

Myka checks her wing mirror. "I think you're being too hard on Rockin' Eddie and Rockin' KDBW, " she says. "He's trying his best to keep Muskogee 'boogeying' thru breakfast'. He's been very clear about this. And anyway, it's not as easy as it seems, being a radio announcer. Especially when you're on air alone, without someone else in the studio to talk to."

"Why, it seems perfectly simple to me," sniffs Helena, "You just open your mouth and say the first silly thing that comes to mind."

"No, there’s actually a lot of preparation and practice involved."

Helena gives Myka a shrewd glance. "You seem to know a lot about the subject. Is this another one of your abandoned careers?"

"I don't have 'abandoned careers'," says Myka, frowning, "Stop saying that. But yeah, I hosted a late night show on college radio for a couple years."

At this Helena sits up straight. "No! Really? Well!" She eyes her companion anew. "You are a dark horse Miss Bering. And so you too, I imagine, would utter those strange animal cries and then exalt your listeners to 'get down to the rhythm while they get up to the java'?"

"No, of course not," says Myka, "It was a late night show. People were going to bed."

Helena, who has been bored and irritable since they left the airport four hours ago — not that she would have admitted this, even to herself — finds that she is now quite cheered up. "And did you also play 'the greatest hits of the '70s, '80s, and beyond'?" She gasps. "Did you play 'Killing in the Name Of'?"

"And did you have a sobriquet? Like Rockin' Eddie?"

Myka shakes her head. "What is it with you and that song? And no, as I said it was a late night show, so it was relaxing music. And my show was mostly modern classical and jazz. Some baroque and early stuff. Some avant-garde." She changes lanes to let another car pass. "College radio is more, uh, eclectic than stations like KDBW Muskogee. People play all kinds of stuff."

Myka pauses. "Uh, yeah."

Helena waits.

Myka clears her throat. "I was, um... Velvet."

"Velvet."

"Yeah. The show was 'Vespers with Velvet'"

Helena considers this. "Surely it should have been 'Compline with Velvet'? If it was a late night show?"

"I know!" Myka grips the stearing wheel tighter. "I told them that! But they said they liked the alliteration. And so I had to introduce 'Vespers with Velvet' every Sunday night knowing it was wrong!" She shakes her head at the old frustration.

"But why 'Velvet' to begin with?" asks Helena. "Please don't misunderstand me, I think you have a lovely speaking voice. But I wouldn’t call it velvety."

"Oh, I didn’t speak like this," says Myka. And then her voice drops an octave. "I spoke like this."

Every hair on the back of Helena's neck stands up. A wave of anticipation passes down from her scalp, running through her body to settle heavily in her centre.

She leans back in her chair and ever-so casually crosses her legs.

"Forgive me," she says, "My mind was momentarily elsewhere. Could you repeat that, please?"

[hapless-studyblr]

so the 60 days of productivity challenge did not work out and that's fine we can always start over. but I've realized the way I've been studying is fragmented and all over the place so I've decided that I must do the following things:

1. Learn java

2. Then finish the kotlin course

3. Then make an app

4. then study more c++

5. then do a project in c++

and this seems very ambitious but I'm not planning to be an expert in these languages anytime soon, just know enough to make stuff and grow my knowledge through practice. ideally I'd like to do all of these things by mid to late October. And I'll do projects throughout the year so I don't forget and can improve :)

I'm starting java today, I'll post a lot here to keep myself accountable and I hope I can do it. I'm excited to learn new languages and build things!

Coding Brushup: Java Exception Handling Best Practices

In this coding brushup session, we focus on one of the most critical aspects of writing reliable and robust Java applications — Java exception handling. Exception handling in Java is not just about catching errors; it’s about managing program flow, providing meaningful feedback, and ensuring your application remains stable and maintainable under unexpected conditions. This article outlines the most effective Java best practices course for handling exceptions, ensuring your skills are current and refined.

Why Exception Handling Matters in Java

Java exception handling is a mechanism that allows developers to manage runtime errors in a graceful and predictable manner. Rather than crashing the application or producing undesired output, exceptions help developers identify problems, apply fixes, and even recover from faults during execution.

As part of any serious coding brushup, understanding Java best practices in exception handling is essential for writing quality, production-ready code. Exception handling not only improves the robustness of the program but also enhances readability, maintainability, and debugging efficiency.

1. Always Catch Specific Exceptions

A fundamental rule in Java exception handling best practices is to catch the most specific exception possible. Catching generic exceptions such as Exception or Throwable should be avoided unless absolutely necessary. Specific exceptions provide more control and clarity over error management.

Catching only relevant exceptions ensures that you’re not inadvertently masking programming errors or swallowing unrelated problems. This promotes more accurate exception tracking and error resolution, which is a core component of professional Java development.

2. Never Swallow Exceptions Silently

One of the most common anti-patterns in Java exception handling is swallowing exceptions without any feedback. Empty catch blocks suppress errors silently, making it difficult to trace and debug problems when they arise. In a good Java coding brushup, it’s vital to emphasize that every caught exception must be logged, re-thrown, or otherwise acknowledged.

Swallowing exceptions hides potential issues and breaks the natural flow of Java best practices. Even when you choose not to halt the application, logging the exception is a must for long-term code health.

3. Use Finally Blocks for Cleanup

The finally block is a staple in Java exception handling. It guarantees that a particular section of code will execute, regardless of whether an exception is thrown or not. This is particularly useful for cleaning up resources like file handles, sockets, and database connections.

Using finally correctly ensures your application does not suffer from resource leaks or dangling operations. This is a vital point in any coding brushup since failing to clean up properly can lead to memory bloat or degraded system performance.

4. Prefer Try-With-Resources for Auto-Closeable Resources

Since Java 7, the try-with-resources statement is the recommended approach to handling resource management. This feature simplifies code and automatically closes resources that implement the AutoCloseable interface.

Using try-with-resources eliminates the need for verbose finally blocks and helps reduce boilerplate code, aligning with modern Java best practices. It’s an essential part of updating your skills in any Java coding brushup session.

5. Create Custom Exceptions Where Necessary

In many scenarios, predefined Java exceptions may not clearly describe the domain-specific problem your application is encountering. In such cases, it is a Java best practice to create custom exception classes.

Custom exceptions improve the semantic clarity of your code and allow for cleaner exception hierarchies. During a coding brushup, it’s crucial to learn how to define and use custom exceptions effectively to make your application self-documenting and easier to debug.

6. Log Exceptions with Proper Detail

Logging exceptions is a key practice in professional Java development. It’s not enough to print stack traces to the console; structured logging using tools like Log4j or SLF4J is far more effective.

Logs should include the exception type, message, and ideally, the stack trace. This level of detail ensures that you can trace the origin of errors and monitor system behavior efficiently. Logging is a routine yet vital aspect of any Java coding brushup, especially for those transitioning into production-level code.

7. Avoid Using Exceptions for Flow Control

Exceptions are meant to handle abnormal conditions, not for standard control flow. Using exceptions to implement conditional logic is an anti-pattern and violates Java best practices.

This approach not only reduces performance due to the overhead of exception handling but also makes code harder to understand. Instead, validate input and use regular control structures for predictable logic. This is a critical distinction in any thorough Java exception handling brushup.

8. Document Exceptions Clearly

Every method that throws exceptions should document them properly using Javadoc comments. This helps other developers understand what exceptions they might need to handle when calling your method.

This practice aligns with writing self-explanatory code and contributes to better collaboration in team environments. Any seasoned coding brushup will stress the importance of documenting thrown exceptions, especially in public APIs or library code.

9. Use Exception Chaining for Better Context

Exception chaining allows developers to pass the original exception to a new exception when rethrowing. This helps preserve the original error stack and provides additional context, which is essential for effective debugging.

Following this practice enables more meaningful and layered error messages, supporting a more holistic understanding of problems during runtime. This nuanced technique is an advanced topic often emphasized in senior-level Java coding brushup sessions.

10. Rethrow Only When Needed

Sometimes, you may need to rethrow an exception after logging or wrapping it. It’s important to do so judiciously, ensuring you’re not duplicating logs or losing stack trace information.

Blindly rethrowing exceptions can clutter logs and confuse the root cause of issues. Instead, when rethrowing, ensure that the context of the exception is either preserved or enhanced. This habit aligns closely with Java best practices and is a mark of mature exception handling.

Conclusion

Exception handling is more than just writing try-catch blocks — it’s about writing intelligent, predictable, and resilient code. In this coding brushup on Java exception handling best practices, we’ve covered essential concepts such as catching specific exceptions, avoiding silent failures, logging effectively, and using modern Java features like try-with-resources.

As a Java developer, refining your exception handling strategy will not only reduce bugs but also improve your codebase’s clarity and maintainability. Make these best practices a consistent part of your Java coding brushup routine to elevate your development skills to the next level.

[izicodes]

Hiya!! I am taking a coding course at a University. While it's excellent for learning how to use a lot of complicated concepts in programming, we don't really get to do any projects or create anything yet. I was wondering how to get into that. Are there any resources you might recommend?

Hiya!! 💞

Goodie, you want to build your own projects! That's so good, I love project building! Now, it depends what you're coding (the languages + specific area) e.g. are you learning HTML/CSS/JavaScript (Website building) or is it like Python/Java/C# idk but you get what I'm asking for here, the projects you want to learn and build depends on what you're learning in the first place! But I will give some general advice!

🎥 YouTube

I love YouTube so much, there are thousands of videos on that site for any programming language to building pretty much anything! What I did when I started off was the simple search of "[The coding language] beginner project" and then I get to see what I can build. Now if you get stuck on a snippet of code, Google it and there are sites that will explain it for you. Now, don't fall for tutorial hell where you're watching tutorial after tutorial videos but watching them will give you a good foundation!

🔍 Google

Similar to what I said for the YouTube way, you can Google the same question and it will give you a bunch of project ideas, how to even do them and all you can do also is add more on top, what I mean is don't just watch or read about a project idea, see how you can twist it your own style e.g. recently I watched a React.js tutorial on how to make a to-do app! My twist was I styled it different by adding a frog theme. So the tutorial was my foundation and I just added on top of that to further exercise my skills!

🌐 GitHub

Have a hub for all your projects! After creating your projects, you don't just want it sitting on your computer, you can put it online! I use GitHub - it's a place where you can store all your projects, have a save history so you can go back on old code, even share the static webpages you make (using HTML/CSS/JavaScript) with other people online! The Site | How to use GitHub | Check out my GitHub for reference

📚 Online Courses

Many online platforms offer project-based courses. Websites like Udemy, Coursera, Codecademy and FreeCodeCamp can guide you through creating practical projects step by step. I use Udemy for learning and there are courses that are like "Build 9 web development projects blah blah blah" they're actually really good! BUT you do have to pay for them but if you can't find a good project on YouTube to follow or you can visualise or understand the articles online on how to build one, I suggest getting a course because someone teaches you how to make the project. Udemy is fairly cheap during their sales, going down from £59.99 to £10.99!

🤗 Collaboration

Reach out to classmates to build together, someone is bound to have an idea for something! Collaborative projects not only expand your skill set but also let you learn from others. Great skill to have! You can even collab on GitHub projects - which I am doing right now with people I've met through Tumblr (checkout our project)!

Remember, Rome wasn't built in a day! Start with small projects, gradually challenging yourself with larger ones. The journey of creating is just as exciting as the finished project itself. Happy coding! ��🙌🏾💻💗

12 february 2024, monday.

my classes will resume in 15 days!!! so i've decided to review some topics i studied in the past semesters. i'm going to focus on calculus 1 because i'll be taking classes on calculus 2. and since we have practical projects every semester, i've started a mini course on it project management too.

now i'm going to focus on reading the java textbook because i believe my professors will choose to use java to teach us the new subjects.

done list:

did 3 italian lessons on duolingo

reviewed flashcards

did a summary on math functions

did half of the first chapter of the it project management course (why does it have to be sooooo long?)

Preparation for the study

Hello guys!

Well, I've been doing a course of java in the past week or so, but I haven't been tracking and I want to keep a progress to be more sure I am in a good pace and will end it (kinda) faster.

So today I am going to pick a schedule and turn it into a habit, also I am going to organize how I will spend my time studying. I am learning Java (still on the very beginning heelp). So far, have made into 55 of 541 videos in the Java course, 77 hours of lessons and there's also practice and some challenges to do. I don't think I am able to get it done if I don't put my effort into being aware of my time, so my biggest flaw here is to keep focus and avoid procrastination at all my costs.

The course abt java has:

-Fundamentals of Java

-Programming oriented object

-Functional programming

-Mysql

-Mongodb

-Spring boot

-Javafx

-JPA

-Hibernate

And when I end this course I will continue with the ""sequel"", my point is to keep learning so I can get a job at the field and move on into being able to buy more books and keep this looping going. As the obsessive I am, I'm fully engaged in tech obviously, so my plans much depends on learning about it, and then how to make everything in my life about it too so... Yeah it will be fun, and a big stress probably. Hope I don't burn my head doing that.

Also, I bought last week a few other courses, cuz they were for such a good price I couldn't say no. Still haven't picked any of them to study, but, respectively they are:

-HTML and Css basics

-Terminal for beginners

-Gnu nano

-Shell script advanced

-Learn to compile

-VPS Server

-Create your own package manager

-Vagrant

-Slackware essentials

-Darkweb

Those are some topics I am interested in, even knowing a little about one here and there, will be a great challenge to advance my comprehension. I need to find time to put them into schedule. Wish me luck everybody. Maybe I am getting too overwhelmed to do everything I picked? Of course, but fuck it I can handle - just not at the same time obviously, sometime I will get there I just need to be patient with myself and keep consistency at check.

Gosh, was a long post huh? I will say later on my plan to get it all done! Until them, thank you for staying with me.
