Our team makes a software in Java and because of technical reasons we require 1GB of memory for the JVM (with the Xmx switch).
If you don't have enough free memory the app without any sign just exits because the JVM just couldn't bite big enough from the memory.
Many days later and you just stand there without a clue as to why the launcher does nothing.
Then you remember this constraint and start to close every memory heavy app you can think of. (I'm looking at you Chrome) No matter how important those spreadsheets or illustrator files. Congratulation you just freed up 4GB of memory, things should work now! WRONG!
But why you might ask. You see we are using 32-bit version of java because someone in upper management decided that it should run on any machine (even if we only test it on win 7 and high sierra) and 32 is smaller than 64 so it must be downwards compatible! we should use it! Yes, in 2019 we use 32-bit java because some lunatic might want to run our software on a Windows XP 32-bit OS. But why is this so much of a problem?
Well.. the 32-bit version of Java requires CONTIGUOUS FREE SPACE IN MEMORY TO EVEN START... AND WE ARE REQUESTING ONE GIGABYTE!!
So you can shove your swap and closed applications up your ass but I bet you that you won't get 1GB contiguous memory that way!
Now there will be a meeting about this issue and another related to the issues with 32-bit JVM tomorrow. The only problem is that this issue only occures if you used up most of your memory and then try to open our software. So upper management will probably deem this issue minor and won't allow us to upgrade to 64-bit... in 20fucking1910
I recently joined a new company where work is quite different than my previous company.
Every day at work is challenging for me. There is good exposure to learn technology in depth. But time constraint to deliver module like under 3 days does not let me learn my work, also I am not satisfy with the quality of my code that I provide, it more looks like a patch. In my previous company I was favorite developer of my team but here I feel like a fresher who doesn't know from where to start.
Even I feel like my presence does not make any impact in office as I am just like an extra player of the team. I am slow at my work because I learn then I code due to which my manager does not consider me for any new work. I feel like left out in my team.
Once I overheard one of my colleague he called me helpless and were making fun of me. With every passing day I am losing my confidence.
I have no github reputation. It's like I am jack of all trades but master of none.
Every day is like big fight day in office.
I know our only way to survive in this industry is to keep on learning but in smart way. I am not sure what's that smart way?
Any advice would be helpful.5
I'm a fan of writing tests right after you write every module. I actually think it's doable.
But I'm not a big fan of traditional TDD, which is defined as: first writing the tests, making them fail, writing code until tests don't fail.
My experience with traditional TDD when writing library code is that you start with this very naive idea of what is needed, so you write classes and functions and a lot of times they look like overly simplistic pseudocode.
So what do you do? You scratch that, you delete those classes/functions several times.
I think this discovery process that your code is naive is slowed the fuck down by doing TDD.
I'd rather write a theoretical API in a readme file, then write code, and then write the tests, you can even withhold writing the tests, but never leaving them for another day, just so that you don't waste time writing tests that you're going to scratch.
There's always a time constraint, and most of us can't afford bikeshedding.
Traditional TDD feels like an esoteric thing, it tries to make programming a series of steps, it actually sounds like an infommercial.

I just read a rant about Java by a guy who moved from JS/python.
FFS, until now you were using some aberration of OOP by creating "objects" and making them however you want instead of sticking to concept of blueprinting and managing your classes in a way shit happens properly.
Yes, I do hate js/python-like langs if I would have to do something big in them, because I need to constraint my program so it works predictably every time. I don't feel like I'm doing that by putting some arbitrary key-value pairs into some random object :v
Java and her sexier sister Kotlin ftw and nothing gonna change my mind <316
Don't you just love it when you ask Hibernate to fetch some data from DB and it does that for you.?And also updates a few more tables on its way. And inserts a few more rows. And updates another couple of fields..
Isn't that just amazing? I mean.. What could be more satisfying than getting an "ORA-00001: unique constraint (some.constraint) violated" while issuing a FUCKING **GET** METHOD?5
Oh boy, kotlin and its world of statics and lambdas are glorious 💗💗💗
I just finished this attendence counter app i have been working on for last 4 days.its quite simple so i tried to add as much constraints as possible:
-Good practices and minimal warningy
-Viewmodel and livedata
-everything in kotlin
Although i already have worked with room and livedata previously but i dont even have a hello world experience in kotlin . However it doesn't felt that bad tho for a newbie
Every code here is so small . Synthetic binding? Love at first sight.Although at some places its irritating , not having ?: Operator or its ugly 'when' logic, but overall its Awesome!!7
!Rant && !Believe what I am seeing 😓
Just downloaded Android studio 3 to give kotlin a go to find out their designer is soooo much better now, I tried editing an activity with constraint layout and many elements inside without a single freez 😨5
Yep, today was a Monday. Had a request to truncate some tables. Set up a script to disable constraints, truncate, and re-enable constraint. It ran flawlessly. Too bad I ran against the wrong schema, though. Ran it against a dev schema instead of the requested itest schema, because the dev schema was stuck in my head. Well, I guess I tested it in dev. Against some developers schema. But, hey, it worked flawlessly. Because, you know, when you are pointing at the wrong place, it will always work. Every time.3
GOD ALMIGHTY I HATE SWIFT & XCODE...
Why the fuck does it take a horrendous amount of time to muck about with layout constraints. Why the heck does xcode choose to add constraint layouts to elements that already have pissing constraints! Why does dealing with something as trivial as tables have to be so god damn fucking involved when HTML and CSS let me create and style tables in fuck all lines.
And what the hell is up with how pissing long xcode takes just to figure out that 1 extra line of code I've just added. You jump to another file and xcode finally decides to be an ide again and bitch at the fact that you've forgotten to add some parameter or that they've decided to rename paramter "x" since version fuck nows what.
Working with abstract classes is fun, lets use protocols (because interfaces are too old school) and then lets tack on something we call extensions and then lets make people piss about with convenience initializers.
And lord almighty, what the fuck is up with casting, what all this ?! BS. What's wrong with just checking if the value is null in the first place, or whats wrong with giving something an initial value, oh because having to unwrap shit is more elegant right??
And good god, I need to own a fucking cinema screen just to have the storyboard open, there's less fucking panels on the Sistine Chapel ceiling
then there is in xcode.1
IT'S CAPS RANT TIME!
MYSQL ERRORS ARE SO USELESS! AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHH
I JUST WANT TO ADD A FOREIGN KEY BUT 'Cannot add foreign key constraint' KEEPS COMING UP, AND THE STACK OVERFLOW ANSWERS INDICATE THAT IT COULD BE -LITERALLY- ANYTHING!
THIS IS OF COURSE, AFTER PHPMYADMIN GIVES ITS OWN ERRORS FOR TRYING TO USE THE DESIGNER TO ADD THE RELATION. IT ONLY WANTS UNIQUE FOREIGN KEYS, DESPITE ONE OF THE MAIN USES OF FOREIGN KEYS BEING MANY-TO-MANY AND ONE-TO-MANY RELATIONS!3
Asking Android Studio to convert your layouts to ConstraintLayout is the equivalent of asking a two legged horse to do your laundry.2
On my home machines, I am a dual booter (job is .net) but Ubuntu is running 90% of time. Last night I tried installing a printer but failed miserably. Due to time constraint I had to boot that fucking resource molester of win10 which sux even more on low end box like mine.
Now am red eyed & angry. Fucking printer .8
Android studio is a PATHETIC excuse of an IDE!! And managing a constraint layout inside a scroll view is worse than having my nails pulled out while a bamboo is growing into my spine at record time! Screw this piece of shit IDE!! I suck at front end bad enough to have to deal with its buggy frontend IDE!! Aaaah!!!! - pulls lumps of hair out-14
Constraint Layout is the best thing Google has ever made for responsive Android design, when it works.
Half the time it suddenly stops finding any elements I want to attach my selected one to, so it can't constrain what I want it to constrain.
A restart fixes it though...1
(Fyi: I was an intern.)
It took me hours of time to recognize, that one of the necessary tables just used an oracleDB Date as a timestamp, which lead to a violation of the primary key constraint on interactions taken place in less than one second.
Me: (explaining the problem to CW)
CW: "Yup, we know."
Him: i get this error when i insert into table, ForeignKey_contraint failed, what can i do?
Me: you have to obey the constraint, make sure it exists in the other table first
Him: ok i did that but i still get ForeignKey constraint error
Me: yeah that table has a couple foreign keys
Him: could you give me a very specific example how to insert into this table
Me: ........ here is a command to remove constraints on the table
Him: thanks, that fixed it!
I am helping a programmer who works with Costco integrate to software my company sells. I don't have source code, just an understanding of the database and what the software does. If he is getting paid more than me, then I should get a job there and ask for double, I could easily work 10 times faster than this buffoon.
Not sure if I am Allowed to ask general questions here but here's the thing. I just began making Android apps. I have made a few basic of them and I use constraint layout via the layout editor in Android Studio. Is it okay? Do professionals do the same or do they actually type in the xml code?14
Took over a project where a dev created a table with no primary key and enforce a unique constraint in code. Wtf? He also always selected top 1 so if you added a record directly in the table it completely fucked the expected data.
So, when I took this piece of shit over I didn't realize what the table was and when I tried to convert it to EF it barfed since there was no PK. Was a complete PITA and had to create all new tables.
Some people shouldn't develop software!!!!!!!!!
Okay so I'm one of those developers who haven't moved to constraint layouts yet. I've been working on heavily nested layouts (for obvious reasons) and the gravity chooses to kill the fun every time :))2
When a section of the database is all using a FK constraint and you've been searching for hours but no table is actually using it as a PK...
After the "Cloud Computing" trend, the new trends these days seems to be ML, VR and AI. And while I am very excited about all these techs and the possibilities it can bring, I can't help feel that most of us are using the term "AI" a bit incorrectly.
What we are trying to do here, as far as I can see, is VI, not AI. The intelligence we see in the so called "AI"s available so far are simulated and fails to emulate real intelligence, let alone demonstrate actual intelligence and awareness. They are not fully aware. But I guess that is why there is the singularity constraint. It is no doubt that when a VI finally becomes are fully aware AI, that is indeed the point of singularity.
Anyway, leaving the future dystopian thoughts aside, a mixture of ML, "AI" and VR have made some very interesting concepts, especially in the gaming industry, which I would love to see bear fruit in the near future.2
I hate AndroidStudio when it adds constraint-layout as a dependency in my build script whenever I create a new Activity.
The bugs that make you think are the best/worst.
Had a ghost foreign key constraint from a dropped table. Cant drop it from a non existant table.
Turns out the dev copied a file for the new table and since you can technically name those foreign keys anything you want, there were no errors when he ran it.
Also sloppy/overworked dev teammates are the worst...
Also I'm pretty sure rule 2 of programming is "Never Copy and Paste"
To all android Devs who used to or still change Constraint layout as the root element of the view despite Google forcing it on us.
Your time is near....
I went remote a year ago and have had the constraint fear of losing my job, even though I know for a fact that there are other devs who do less work than me and slump around more than me. Never want to go back to office life again though.1
Getting a duplicate record error in MySQL from a unique key constraint. Trying to decide if I should fix the Java code that possibly sending a duplicate save || drop the unique constraint from the table? 😂😂😂3
# ./symfony test:unit
Propel-Exception: Unable to execute DELTE ALL statement [...] Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails.
WHY ist a UNIT TEST reaching out to a REAL data base?
And who in their right mind would create a different data base schema for the tests?
This was with a clone of the real thing. Removing the FK results in double PK-errors...5
Rant! When you live in a less technically advanced country, and everyone cheaps out on their software and hires the company that will do it for the least money and because of that it never works decently you can't reserve movie tickets on the cinema's site and get a SQL constraint error directly on screen, if you can't afford custom software buy a license for something that works out of the box ffs
(I'm goin' to see Star wars ofc.)2
Anyone who tells you there is no time constraint is on drugs. There's no such thing. At best, there are just secret deadlines that crop up as you're getting close. It's just a fucking con to get you to build unimportant shit, and work your ass off to meet some artificial deadline at the end.
Got an assignment yesterday. I was required to create an Android app. I used constraint layout for the app. However, instructor told me today not to use constraint layout. Instead use relative layout. He did not gave any explanations for it. What you think might be the reason? How many of you still use relative layout, and why?1
Am I the only one waving around when working with the Constraint Layout in android....feeling like am directing traffic
