Holy fucking shit. I just went to my first Java class at uni (3 1/2 hour long one at that) and I havent felt so damn irritated in a while.
Some background:
So first, I only had about an hour of sleep last night and a full day of work before this class so I was more cranky than normal.
Theres only 7 students in the class, 6 others plus me. I am the only one with any resemblence of programming experience. The teacher also claims to be a linux developer.
This is a three part course series. Java 1, 2, and 3. All taught by the same teacher.
The fuckery:
-teacher spends 48 minutes talking about text editors. Not even IDEs. Just talking in depth as fuck about notepad (notepad. Not notepad++ )and atom and textpad. Those three only though, nothing on vim or emacs or ACTUAL IDEs. 48 minutes.
- I briefly mentioned learning node.js on the side and am now the "javascript girl" to my teacher. I'm probably less experienced with js than any other thing i ever practised or studied.
-professor saw linux on laptop and asked what distro. When I said arch he said "oh no you shouldnt be using that Its not really for beginners" ... Uhh what makes you think I'm a beginner to linux? Or does he not think I should be using arch while learning java? Either way its really ridiculous and irritates me that he would discourage anyone from using any software/OS/anything, regardless of what it is or skill level.
-teacher moved a bunch of content out of the course because theyre either "concepts that are never implemented anymore" or "arent critical to know to master the language". These particular topics that were removed? Multi-dimensional arrays, scopes, and exception handling. EXCEPTION HANDLING.
-he writes a hello world program and displays it on the board, proof of it working and everything. He tells the class to write the same program, compile and run it. Never did I guess we would spend the remaining hour and ten minutes of class struggling with fucking hello world programs. Especially when the correct code is on the fucking projector.
And I get it guys, everyone starts somewhere. People have to learn from square one. But these kids have no fucking interest in this. One of them literally admitted to pursuing this degree for the "lavish life" that comes with the salary. Others just picked programming because they didnt know what else to choose to get into the school. It fucking saddens me. I hope that one or some of them end up caring and finding a passion in this field, otherwise I feel fucking sorry for them having to spaghetti code their way through life to get a paycheck cause they couldnt be bothered to put in the effort. I feel even more sorry for any devs they work with in the future too.
The other annoying bit is that I can't test out of this class!! so it looks like for either 7 hours a week ill be bored out of my fucking mind with these beginner concepts or ill be helping others fix really stupid shit in their code (like putting quotes around hello world so it would actually print the string).
Fucking hell. Waste of a semester class.44 -
I'm drunk and I'll probably regret this, but here's a drunken rank of things I've learned as an engineer for the past 10 years.
The best way I've advanced my career is by changing companies.
Technology stacks don't really matter because there are like 15 basic patterns of software engineering in my field that apply. I work in data so it's not going to be the same as webdev or embedded. But all fields have about 10-20 core principles and the tech stack is just trying to make those things easier, so don't fret overit.
There's a reason why people recommend job hunting. If I'm unsatisfied at a job, it's probably time to move on.
I've made some good, lifelong friends at companies I've worked with. I don't need to make that a requirement of every place I work. I've been perfectly happy working at places where I didn't form friendships with my coworkers and I've been unhappy at places where I made some great friends.
I've learned to be honest with my manager. Not too honest, but honest enough where I can be authentic at work. What's the worse that can happen? He fire me? I'll just pick up a new job in 2 weeks.
If I'm awaken at 2am from being on-call for more than once per quarter, then something is seriously wrong and I will either fix it or quit.
pour another glass
Qualities of a good manager share a lot of qualities of a good engineer.
When I first started, I was enamored with technology and programming and computer science. I'm over it.
Good code is code that can be understood by a junior engineer. Great code can be understood by a first year CS freshman. The best code is no code at all.
The most underrated skill to learn as an engineer is how to document. Fuck, someone please teach me how to write good documentation. Seriously, if there's any recommendations, I'd seriously pay for a course (like probably a lot of money, maybe 1k for a course if it guaranteed that I could write good docs.)
Related to above, writing good proposals for changes is a great skill.
Almost every holy war out there (vim vs emacs, mac vs linux, whatever) doesn't matter... except one. See below.
The older I get, the more I appreciate dynamic languages. Fuck, I said it. Fight me.
If I ever find myself thinking I'm the smartest person in the room, it's time to leave.
I don't know why full stack webdevs are paid so poorly. No really, they should be paid like half a mil a year just base salary. Fuck they have to understand both front end AND back end AND how different browsers work AND networking AND databases AND caching AND differences between web and mobile AND omg what the fuck there's another framework out there that companies want to use? Seriously, why are webdevs paid so little.
We should hire more interns, they're awesome. Those energetic little fucks with their ideas. Even better when they can question or criticize something. I love interns.
sip
Don't meet your heroes. I paid 5k to take a course by one of my heroes. He's a brilliant man, but at the end of it I realized that he's making it up as he goes along like the rest of us.
Tech stack matters. OK I just said tech stack doesn't matter, but hear me out. If you hear Python dev vs C++ dev, you think very different things, right? That's because certain tools are really good at certain jobs. If you're not sure what you want to do, just do Java. It's a shitty programming language that's good at almost everything.
The greatest programming language ever is lisp. I should learn lisp.
For beginners, the most lucrative programming language to learn is SQL. Fuck all other languages. If you know SQL and nothing else, you can make bank. Payroll specialtist? Maybe 50k. Payroll specialist who knows SQL? 90k. Average joe with organizational skills at big corp? $40k. Average joe with organization skills AND sql? Call yourself a PM and earn $150k.
Tests are important but TDD is a damn cult.
Cushy government jobs are not what they are cracked up to be, at least for early to mid-career engineers. Sure, $120k + bennies + pension sound great, but you'll be selling your soul to work on esoteric proprietary technology. Much respect to government workers but seriously there's a reason why the median age for engineers at those places is 50+. Advice does not apply to government contractors.
Third party recruiters are leeches. However, if you find a good one, seriously develop a good relationship with them. They can help bootstrap your career. How do you know if you have a good one? If they've been a third party recruiter for more than 3 years, they're probably bad. The good ones typically become recruiters are large companies.
Options are worthless or can make you a millionaire. They're probably worthless unless the headcount of engineering is more than 100. Then maybe they are worth something within this decade.
Work from home is the tits. But lack of whiteboarding sucks.37 -
Me (experienced java dev) in an interview..
C: „what’s the difference between equals and equals equals and equals equals equals in js?“
Me: *i explained it perfectly*
C: „what’s the difference in Java between equals and equals equals and dot equals?“?
Me: „sorry, I don’t know. I’ve never ever seen .=„..
About 15 min after the interview, I was like: „holy moly fucking shit, please shoot me.. he meant .equals.. not .=....
For the devs: I‘M FUCKING STUPID!!!!
For the beginners: THATS the importance of „context“!4 -
What do you guys think of codecademy, free code camp and their likes? Please recommend good learning platforms better than these for absolute beginners.
Also can you use android studio for java programs and not just android apps?17 -
University, first year. I went to my Java/OOP teacher's office to about the course (I had started programming C++ ~5 years ago).
I wanted to discuss the fact that some parts of the course seemed too theoretical for beginners in my opinion. Rookie mistake : do not criticize the cursus of an academic if you are in your first year, even when you are right. I learned it the hard way...
The teacher started to tell me that I was just a first-year student, I had no experience yada yada...
To that I replied "I'm doing C++ for 5 years. This is OOP so yeah I do know a little more than you think".
I will never forget his reply "LOL C++ is not Object-Oriented !"
I never went to his course after that. I learned a few years later that the teacher was a well-known a**hole along his peers and got fired by the University...40 -
I know I’ll get mixed views for this one...
So I’ll state my claim. I agree with the philosophy of uncle bob, I also feel like he is the high level language - older version of myself personality wise.. (when I learned about uncle bob I was like this guy is just like me but not low level haha).
Anyway.. I don’t agree with everything because I think he thinks or atleast I get the vibe he thinks everything can be solved by OOP, and high level languages. This is probably where Bob and I disagree. Personally I don’t touch ruby, python and java and “those” with a 10 foot pole.
Does he make valid arguments, yes, is agile the solve all solution no.. but agile ideas do come natural and respond faster the feedback loop of product development is much smaller and the managers and clients and customers can “see things” sooner than purly waterfall.. I mean agile is the natural approach of disciplined engineers....waterfall is and was developed because the market was flooded with undisciplined engineers and continues to flood, agile is great for them but only if they are skilled in what they are doing and see the bigger picture of the forest thru the trees.. which is the entire point of waterfall, to see the forest.. the end goal... now I’m not saying agile you only see a branch of a single tree of the forest.. but too often young engineers, and beginners jump on agile because it’s “trendy” or “everyone’s doing it” or whatever the fuck reason. The point is they do it but only focus on the immediate use case, needs and deliverables due next week.
What’s wrong with that?? Well an undisciplined engineer doing agile (no I’m not talking damn scrum shit and all that marketing bullshit).. pure true agile.
They will write code for the need due next week, but they won’t realize that hmm I will have the need 3 months from now for some feature that needs to connect to this, so I better design this code with that future feature in mind...
The disciplined engineer would do that. That is why waterfall exists so ideally the big picture is painted before hand.
The undisciplined engineer will then be frustrated in the future when he has to act like the cool aid man thru the hard pre mature architectural boundaries he created and now needs links or connections that are now needed.
Does moving to agile fix that hell no.. because the undisciplined engineer is still undisciplined.
One could argue the project manager or scrum secretary... (yes scrum secretary I said that right).. is suppose to organize and create and order the features with the future in mind etc...
Bullshit ..soo basically your saying the scrum kid is suppose to be the disciplined engineer to have foresight into realizing future features and making requirements and task now that cover those things? No!
1 scrum bitch focuses too much on pleasing “stake holders” especially taken literally in start ups where the non technical idiots are too involved with the engineering team and the scrum bastard tries to ass kiss and get everything organized and tasks working so the non technical person can see pretty things work.
Scrum master is a gate keeper and is not needed and actually hinders the whole process of making a undisciplined engineer into a disciplined engineer, makes the undisciplined engineer into a “forever” code grunt... filling weekly orders of story points unable to see the forest until it’s over because the forest isn’t show to the grunt only the scrum keeper knows the big picture..... this is bad this is why waterfall is needed.
Waterfall has its own problems, But that’s another story for another day..
ANYWAY... soooo where were we ....
Ahh yess....
Clean code..
Is it a good book, yes.. does uncle bobs personality show thru the book .. yes lol.
If you know uncle bob you will understand what I just did with this post lol. I had to tangent ( at least mine was related to the topic) ...
I agree with the principles of the book, I don’t agree with the extreme view point. It’s like religion there’s the modest folks and then there are the extremists. Well he’s the preacher of the cult and he’s on the extreme side.. but that doesn’t mean he’s wrong.. many things he nails... he just hits the nail thru the wall just a bit.
OOP languages are not the solution... high level languages do not solve everything.. pininciples and concepts can be used across the board and prove valuable.. just don’t hold everything up like the 10 commandments of which you cannot deviate from.. that’s the difference here I think..
Good book, just don’t take it as the Bible as a beginner, actually infact DONT read this book as a beginner. Wait a bit learn then reflect by reading this.15 -
Well this is the thing. I have been starting to replace a lot of my shit with Golang. I think it is a great language because of one small fact: it is a boring language.
With this I don't mean that it is not incredibly fun to use. It is and honestly I feel that a lot of the concepts that I had from C passed quite nicely with some additions. The language does not do anything special and there is no elegant code. It works in a very procedural fashion without taking into consideration any of the snazzy things found in JS, Python, c# etc etc. Interfaces and struct make sense to me, way more than oop does in other languages. I don't need generics with the use of interface parameters and I have hadly found a situation in which I have to strive too far away from the way things are done with Go to be happy with it, then again my projects are not hard or by any means groundbreaking (most of them deal with logistics or content management and a couple of financial apps that I am rewriting in Go from work)
The outcome is fast and easy to read since idiomatic go is for the most part very readable(no people...single letter variable names are by no means a standard and they should feel ashamed from it)
I miss the idea of a framework, but not so much and the docs and internal code for Go is just way top inviting. I believe the code to be readable enough than anyone that has gotten used to the syntax and ideas of the language can just jump in and start learning. This is the first language that I have learnt from studying the code as it is inside of the standard lib, the same I cannot say for any other language or framework.
Also, it play beautifully nice with vs code.
I dunno man, I feel that I am doing something wrong. I have projects built in Node, php, python, ruby and spring java as well as .net core and I still find Golang way more appealing simply because it goes harder than Python with "one preferred way" to do things.
The lang does not make me feel like a pro, i certainly develop in it at pro speeds, but it was made with beginners in mind to built fast and concurrent apps, with the most minimal syntax possible.
I guess my gripe with it is that it gets shunned from this, saying that it ignored years of lang research to make it as dumbed down as possible. Which it did, lack of generics amongst other things certainly make it seem like, but I will not say that it was poorly designed. Not at all, I believe it is a testament of amazing engineering. To be able to create such a simple yet amazingly powerful language.
Wish there were more to it. Wish there was a nice gui lib or a ml framework comparable to the ones offered by python and java. But I guess such things will come with time.
I feel stupid with this language.
And that is fine.5 -
One of the things that I like the most regarding Clojure(and most Lisps to be honest) is how "not for beginners" the ecosystem feels.
Don't get me wrong, setting up a project in lein with dependencies(both internal and external) is a cakewalk, installing lein or boot is a cakewalk. Setting environment consts and middleware etc etc is a cakewalk.
Its just that there are no blogs about convoluted and amateurish ways of doing things. Most presentations and articles are written by really experienced and talented individuals.
I dunno, its just a nice shift in community. Its nice to see people not fucking up Object Oriented programming in java or any of the other oop languages. Its nice not seeing people giving horrible advice regarding memory management in C or c++ and it is sure as shit nice to not see spaghetti php und js code.
And my productivity levels are off the charts man. Really liking this shit and I get to stay inside my JVM -
I want to rant about tech YouTubers. As one myself, I feel like I do an even exchange with my viewers.
I want your attention, I don't feel like I deserve it, so I teach you something coding related. You get something of value, I get your attention.
But that's not the case with most in this space. Idiots feel like they can spout whatever bullshit they think about.
They're all stupid with their stupid fucking titles and ideas. Let's review some.
Video Title: How much Javascript you should know to get in tech??
Anyone with > 2 braincells: WTF !!!!!
Video Title: How would I start over to learn coding if I could?
My Reaction: Nope, I wouldn't. The things that I did and didn't is exactly what my journey is and I would do it all over again.
And I get the intent, you're trying to put a roadmap for beginners but they're not going to follow exactly how you lay it out. And why are you trying to establish that there is a correct way of learning coding? Everyone learns at different paces at different times. It's a journey not a race.
Video Title: A day in the life of {COMPANY} engineer.
My Reaction: What do you want to show everyone? Your fancy office? Your perks? The job perks which 99% of other devs won't have?
Video Title: How to crack FAANG interviews.
My Reaction: Well, only the top 1% is going to get an interview anyway. You're not acknowledging the fact that the acceptance rate is < 1% in these companies. Creating a video like this creates false expectations in beginner's heads. And they only see these companies as their only shots of making careers. They dont consider startups or starting their own companies.
Video Title: Top 4 dying programming languages.
My Reaction: WTF !!! COBOL was invented in 1959 and there still is demand for it. And my blood started boiling when Tiff in Tech said PHP is a dying language. Like seriously????
Video Title: Top paying programming languages in 2023.
My Reaction: Please, come on. We know it's Java. And 99% of the viewers ain't getting that job. You're just wasting time listing out languages. By the time someone starts from scratch and gets to a position of getting a job, something else will be the new fad.
Video Title: What advice would I give myself when I was starting?
My Reaction: Really? You couldn't think about saying what advice you'd give to your viewers? Are you really that full of narcissism?
There are good techies though, it's just that I get angrier and angrier the more YouTube recommends me these stupid videos. Ah, my chest feels lighter now.6 -
I feel like writing or telling people about the time I jumped from Windows 7 Ultimate and jumping to Windows 10. (I'm not against 10, but I'm never updating after what had happened to me)
It all starts when none of my games will play due to a possible issue with my graphics card. I look up "3D source game bug" and not many results pop up. I go on Microsoft's Qna areas and ask this question but to my surprise nothing they say would make sense. "Clean the pins of your graphics card, make sure you verify the games on Steam". I verified the games and they checked out as perfectly fine. I don't have access to my graphics card because this is a laptop, sadly not a tower.
Two months pass and my computer is already showing signs of stress, like it didn't want to live in a sense. It was three times slower than when I was on Windows 7 and it was unallocating areas of my main hard drive where I could make virtual hard drives.
Instantly I start looking up Linux distros and find Linux Mint. 17.3 was the current version at the time. I downloaded it and burned it onto a DVD-rom and rebooted my computer. I loaded into the disc and to my surprise it seemed almost like Windows 7 apart from the Linux part. I grab my external hard drive and partition it to hold the Linux distro and leave it plugged in incase Windows 10 does actually fail.
On December 19, a few months after Windows 10 had released. I start my laptop to try and continue my studies in video game development. But to my surprise, Windows 10 had finally crashed permanently. The screen flickered blue and black, and an error box saying Loginui.exe failed to start. I look at it for a solid minute as my computer had just committed suicide in a sense.
I reboot thinking it would fix the error but it didn't. I couldn't log in anymore.
I force shutdown the laptop and turn it back on putting it into safe mode.
To my surprise loginui.exe works and I sign in. I look at my desktop, the space wallpaper I always admired, the sound files, screen shots I had saved.
I go into file explorer and grab everything out of my default hard drive Windows was installed on. Nothing but 400gb got left behind and that was mainly garbage prototypes I had made and Windows itself. I formatted my external hard drive and placed everything on it. Escaping Windows 10 with around 100GB of useful data I looked at the final shutdown button I would look at.
I click it and try to boot into normal Windows 10. But it doesn't work. It flickers and the error pops up once more.
I force it to shutdown and insert the previous Linux Mint disc I made and format the default hard drive through Linux. I was done. 10 gave me a lot of shit. Java wouldn't work, my games has a functional UI but no screen popped up except a black abyss and it wouldn't even let me try to update my graphics card, apparently my AMD Radeon 5450 was up to date at the AMD Radeon 5000's.
I installed Linux Mint and thinking the games would actually play I open steam and Launch Half-Life 2 to check if Linux would be nicer to me than Windows 10 had been.
To my surprise the game ran. The scene from Highway 17 popped on screen and the UI was fully functional. But it was playing at 10-15fps rather than the usual 60-70fps. Keep look at my drivers and see my graphics card isn't in use. I do some research and it turns out I have a Hybrid Laptop.
Intel HD Graphics and an AMD Radeon 5450 and it was using the Intel and not the AMD. Months of testing and attempts of getting the games to work at high frame rates pass and the Damn thing still functions at a low terrible fps. Finally I give up. I ask my mom for a Windows 7 disc and she says we can't afford it. A few months pass and I finally get a Windows 7 installation disc through money I've saved up. Proudly I put it into my optical disc drive and install it to my main hard drive deleting Linux completely. I announced to all my friends my computer was back in working order and I install everything I needed, Steam, Skype, Blender, and Unity as well as all my games. I test Half-Life 2 and it's running exceptionally smoothly, I test Minecraft at max settings and it's working beautifully. The computer was functioning properly once again and my life as a developer started as I modeled things and blender, learned beginners C# and learned a lot of Batch. Today the computer still runs at a great speed and I warn others of what happened to me after I installed Windows 10 to my machine if they are thinking of switching from 7 or 8 on an older machine.
Truly the damage to my data cannot be undone. But the memory of the maintenance, work, tests, all are a memory of how Windows 10 ruined me and every night before the one year anniversary of Windows 10's release, I took out the battery of my laptop and unplugged it from the a.c. power, just so Windows 10 doesn't show it's DLLs, batch scripts, vbs scripts, anything on my computer. But now, after this has happened and I have recovered, I now only have a story to tell5 -
If languages had slogans...
1) Java -- Buy one get two for free on your delicious NPEs.
2) C -- I burn way too much calories talking, let's do some sign language. Now see over there... 👉
3) Python -- Missing semi-colon? Old method. Just add an extra space and watch the world burn.
4) C++ -- My ancestors made a lot of mistakes, let's fix it with more mistakes.
5) Go -- Meh. I can't believe Google can be this lazy with names.
6) Dart -- I'm the new famous.
7) PHP -- To hide your secrets. Call us on 0700 error_reporting(0)
8) JavaScript -- Asynchronous my ass!
9) Lua -- Beginners love us because arrays start at 1
10) Kotlin -- You heard right. Java is stupid!
11) Swift -- Ahhh... I'm tasty, I'm gonna die, someone please give me some memory.
12) COBOL -- I give jobs to the unemployed.
13) Rust -- I'm good at garbage collection, hence my name.
14) C# -- I am cross-platform because I see sharp.
15) VB -- 🙄
16) F# -- 😴8 -
It started when i was about 10 old.
My uncle showed me how to display something in dos-prompt using the echo command in a custom batch-file.
A few commands later, i was able to "program" a flip-book of an ascii ski-driver. Each ascii picture was separated by pressing any key and cls ^^
Aaaaah. Sweet childhood memories!
Later on i used a programming-language for beginners in windows.
This language gave you control of a triangle called "turtle".
My first high-level programming language was Delphi.
Since i had no idea of databases, i created a pseudo database of magic the gathering play-cards. Each card had it's very own windows formular filled up completely with an uncompressed image object displaying the chosen card modally. *sigh*
I scanned each card by using a feed scanner.
Finally, my application consisted of 200 cardimages and forced my PC to swap the required memory from my harddisk.
Boy o boy. I was such a noob! ^^
Over the years i discovered and felt in love with a lot of languages (jsp, java (script), c#, php, ...) and concepts (mvvm, mvc, clean-architecture, tdd, ...)! ;) -
1. Reading eBook “Beginners in vb6”
2. Made a calculator with vb6 to help me in Math homework
3. Made few other desktop apps on vb6 for fun
4. Got interested in Websites so started with WYSIWYG Microsoft FrontPage
5. Started learning frontend and backend coding from WYSIWYG Dreamweaver (HTML, CSS, jQuery, MySQL and PHP)
6. Then custom coding on Sublime. Made around 6 side projects (HTML, CSS, jQuery, MySQL and PHP)
7. Started learning core JavaScript and followed by other programming languages
8. Interest came in making Android and iOS apps. I learnt Java and Swift for it
9. Now I span between Web and Mobile Apps -
What do you guys think of forced linters (checkStyle) on java assignments?
At this University we have a submission system that checks for your code where if a line didn't match the coding specification then it's an instant zero.
Being experienced in programming before going to a university, this somewhat surprised me, it also has unit tests implemented in it where it checks against input and output.
Would love to hear your thoughts on this. Is it too much for people who unlike me never seen code before? Or let them have hell and understand how to deal with it? I personally think it's too much for beginners.3 -
Wrote a new article "Kung Fu Java". Hopefully useful for beginners and entertaining for all.

Good java books for beginners:
Moksh Jawa's book "Decoding Computer Science A"
Herbert Schildt's book (Oracle Press)
The Litvins' book "Java Methods"2
