Google: this sha-1 collision is really gonna fuck up the internet more than anything else today

Cloudflare: hold my beer

Me : I'll make a small game in an hour or so.

12 hours later

Me: It's almost done just need to fix some collision

6 hours later

Me: Just need to fix the speed .

12 hours later

Me : ... the game, it is not finished yet ...

Admin work, because its all manual:

- Each new project has to fill out an Excel tab in a workbook, with a list of all the major tasks and who is responsible. This then needs to be used to create a Gantt chart, manually, in the same tab, showing in what month a task starts and ends.

- Every month we have to manually enter status updates into a powerpoint slide on a shared deck. Which has a collision at least once per month.

- Once a quarter we need to do something similar as the powerpoint slides, but into a word doc instead.

- Once a week we need to track our time on projects in a tool that can't be integrated with (no API or anything). Meaning we can't link up a ticket tracking system to it, so again, all manual.

- Once every 6 months a new round of research funding opens up and we write proposals. The status for which are tracked in another Excel spreadsheet, manually, once a week until the deadline.

- The instructions for what to do with the proposals are so vague and badly documented that there is an unwritten rule, that for the first time you will have to ask a bunch of questions to the project manager. This is accepted by everyone and its just the done thing.

- Everything is stored in a dropbox style system, which has become so cluttered I can only find resources by saving the links sent out previously.

- Some of these updates / reports also get a 1 hour meeting for everyone to stand up and read out what they've entered.

- From time to time random things will need to be reported on to the higher ups (how many publications, research papers, patents, times and dates etc.). Again rather than a tool, a new Excel spreadsheet is whipped up and emailed to everyone on the team. Whoever sent it out, then has to merge the 20+ copies into 1 doc.

- Some of the staff (mostly the devs), use a ticket tracking system to keep track of everything. Management refuse to use it to track the things they need. Instead we have to copy paste from it into the word docs, powerpoint, excel etc.

- By far the most annoying. Management force all the above as they need the info for finance, accounting, legal etc etc. So we have to do it, but whenever there is a question from legal, management send the question to us. So despite having documented every facet of everything imaginable, it all gets ignored in favour of endless emails.

I once tried to to put an end to all of this madness by proposing the use of a ticket tracking system, and then building reporting tools on top of it.

... I was told that it "wasn't appropriate". Still don't know what that means.

It's pretty good deal, if you ask me !!
Gotta buy one, so that I can be online even after I'm dead, earth gets destroyed, sun gets turned into Black hole and collision of milky way and Andromeda Galaxies.

How do I don’t over complicate things?

Background: I’m currently working for a game with some base project. It alr has pretty complicated ai and some other system.

Today, I was asked by boss to help him set up a test environment for testing taking damage of a character.

First I tried to read up how the battle system and ai works in the base project. Figured, it’s overkill for this testing purpose.

Then, tried to use some plugin to automate the ai and movement. Make the enemy follow the target and stuff.

Alr spending half day, then suddenly realised all I need is just to make one script that takes damage on collision.

Why am I still a programmer? 😭

an 18 year old youtube multimillionaire known as McSkillet lost $200,000 on csgo skins and $700,000 gambling and trading csgo skins so he fell into depression. he took his $265,500 McLaren supercar and ran into the highway in opposite direction to commit suicide, but in doing so he also killed a mom and a 12 year old girl from the car collision explosion.

life is very hard to be an 18 year old teenage millionaire, better commit suicide instead.

how do you guys feel about this?

So, I'm still not certain if it's actually a bug or merely my lack of experience, but I've been working on a 2D platformer game (using only C++ and SDL2) for roughly 2 years now (on and off; sometimes off for months) and I'm extremely embarrassed about this, but for the life of me, I cannot seem to get the player character's movement and collision physics working properly. It's driving me absolutely insane.

I've read articles and tutorials, referenced books, and posted about it in game development communities (e.g., gamedev.com, Discord servers, etc.), but even though the fundamental structure and explanations made sense, getting the code to work has been unsuccessful, albeit not completely so, but if I get one thing working, another thing breaks. It feels like I'm trying to repair a vase that fell off of a skyscraper and turned to dust on the street below.

I've always been a very tech savvy person with a fiery passion for programming, electronics and game/software/embedded/web development, but to be honest, having such a difficult time with things like this that — in theory, at least — seem like trivial bumps in the road have made me feel like I'm never going to be successful in this field. But regardless of the depressing thoughts of worthlessness, my passion doesn't let me stop trying. Who knows, maybe it'll have to remain just a hobby. 😕

When you have to made a little game with javascript, and because it's your first game you made a beautiful maze with lot of wall.

Ahahah... i'm shit.
I forgot wall have collision.

I'm here now, with 40 different fuckin' walls and much if and else if conditions.

I hate me.

Yeah i know, I can just change my maze but no... I'm lazy. Cry against the collisions is better.

Have good day.

I had an idea because the Czech Railways keep complaining that someone needs to develop a system that would detect cars and people on railroad crossings... I would call it TCAS - Traffic Collision Avoidance System (just like the one used in airplanes) ... someone already made one, and named it TCAS :-|

Major rant incoming. Before I start ranting I’ll say that I totally respect my professor’s past. He worked on some really impressive major developments for the military and other companies a long time ago. Was made an engineering fellow at Raytheon for some GPS software he developed (or lead a team on I should say) and ended up dropping fellowship because of his health. But I’m FUCKING sick of it. So fucking fed up with my professor. This class is “Data Structures in C++” and keep in mind that I’ve been programming in C++ for almost 10 years with it being my primary and first language in OOP.

Throughout this entire class, the teacher has been making huge mistakes by saying things that aren’t right or just simply not knowing how to teach such as telling the students that “int& varOne = varTwo” was an address getting put into a variable until I corrected him about it being a reference and he proceeded to skip all reference slides or steps through sorting algorithms that are wrong or he doesn’t remember how to do it and saying, “So then it gets to this part and....it uh....does that and gets this value and so that’s how you do it *doesnt do rest of it and skips slide*”.

First presentation I did on doubly linked lists. I decided to go above and beyond and write my own code that had a menu to add, insert at position n, delete, print, etc for a doubly linked list. When I go to pull out my code he tells me that I didn’t say anything about a doubly linked list’s tail and head nodes each have a pointer pointing to null and so I was getting docked points. I told him I did actually say it and another classmate spoke up and said “Ya” and he cuts off saying, “No you didn’t”. To which I started to say I’ll show you my slides but he cut me off mid sentence and just yelled, “Nope!”. He docked me 20% and gave me a B- because of that. I had 1 slide where I had a bullet point mentioning it and 2 slides with visual models showing that the head node’s previousNode* and the tail node’s nextNode* pointed to null.

Another classmate that’s never coded in his life had screenshots of code from online (literally all his slides were a screenshot of the next part of code until it finished implementing a binary search tree) and literally read the code line by line, “class node, node pointer node, ......for int i equals zero, i is less than tree dot length er length of tree that is, um i plus plus.....”
Professor yelled at him like 4 times about reading directly from slide and not saying what the code does and he would reply with, “Yes sir” and then continue to read again because there was nothing else he could do.

Ya, he got the same grade as me.

Today I had my second and final presentation. I did it on “Separate Chaining”, a hashing collision resolution. This time I said fuck writing my own code, he didn’t give two shits last time when everyone else just screenshot online example code but me so I decided I’d focus on the PowerPoint and amp it up with animations on models I made with the shapes in PowerPoint. Get 2 slides in and he goes,
Prof: Stop! Go back one slide.
Me: Uh alright, *click*
(Slide showing the 3 collision resolutions: Open Addressing, Separate Chaining, and Re-Hashing)
Prof: Aren’t you forgetting something?
Me: ....Not that I know of sir
Prof: I see Open addressing, also called Open Hashing, but where’s Closed Hashing?
Me: I believe that’s what Seperate Chaining is sir
Prof: No
Me: I’m pretty sure it is
*Class nods and agrees*
Prof: Oh never mind, I didn’t see it right

Get another 4 slides in before:
Prof: Stop! Go back one slide
Me: .......alright *click*
(Professor loses train of thought? Doesn’t mention anything about this slide)
Prof: I er....um, I don’t understand why you decided not to mention the other, er, other types of Chaining. I thought you were going to back on that slide with all the squares (model of hash table with animations moving things around to visualize inserting a value with a collision that I spent hours on) but you didn’t.
(I haven’t finished the second half of my presentation yet you fuck! What if I had it there?)
Me: I never saw anything on any other types of Chaining professor
Prof: I’m pretty sure there’s one that I think combines Open Addressing and Separate Chaining
Me: That doesn’t make sense sir. *explanation why* I did a lot of research and I never saw any other.
Prof: There are, you should have included them.
(I check after I finish. Google comes up with no other Chaining collision resolution)

He docks me 20% and gives me a B- AGAIN! Both presentation grades have feedback saying, “MrCush, I won’t go into the issues we discussed but overall not bad”.

Thanks for being so specific on a whole 20% deduction prick! Oh wait, is it because you don’t have specifics?
Bye 3.8 GPA

Is it me or does he have something against me?

This semester, we have a lecture called IT Security by a guy, who absolutely know his subject.
Nevertheless, he wanted to show us that sha256 is broken by an existing collision. (Google that, fellow ranters!)
There are two pdf files by google researchers, that show the caption „SHAttered“ both on different backgrounds, although they give the same SHA-hash.
He then tried to share us these two files by moodle and wondered, why he uploaded the same file twice.
Guess what happened? The moodle backend checks new uploaded files for their ... hash ... and then decides, weather to upload or the file is already existing. So, it did just a new symlink to the old file.
Ironic, that an exercise, that should show us sha collision failures on sha collision 😃

"Hey i see you use a CollisionShape2D to detect collision, now go fuck yourself because only Area2D supports custom collision signals"

Ok thanks

If life gives you key, hash it without collision 😀

Question and Update.
First of all, I would like to thank @ScriptCoded for an idea in the previous post, so then I have beautiful terrain now, and the complete world map generated like plots, and each of them consists of 5x5 different plots defined by neighbors :) Hired a digital artist who is working on much nicer plots as well.

The new issue is regarding the zoom.
The map is saved as JSON with the pixel-perfect location of each generated plot so I am detecting the collision with the mouse based on their location. After I zoom in, the script is still comparing the pixel location of the element, but the real screen is scaled already so the pointer is off (image2). The problem is described in image3 as well. How can I still get the canvas relative value of the mouse instead of the x,y coordinate on the current zoomed screen?

my longest coding session was from 10am to 2am, so 16hrs
was in first semester of uni and we had to build the game "breakout" using a predefined guideline.
i had to program the collision detection of a ball against some blocks that had to be destroyed
took a long time for me to do the task, as i'm not the fastest coder (and often neither the smartest😅) and had to fight a bunch of bugs too.
in the end it kind of worked but the performance was horrible at best

In my previous rant i complained about no irregular sprite collision detection libraries.

So after messing up with curves and line in p5.js I gave up on creating the fish like a complete caveman.

I wrote a simple vector paint program which can return the set of points on console logging, and here is the result

Achieving decent 2D collision detection using ray casting in unity is kinda hard. I have immense respect for gameplay programmers.

I'm almost there though...

Ok people told me to make a collision library...um really stupid question but I’ve never tried that or thought of it. Thank you in advance but does anyone want to point me toward some nice resources... THANKS also I did ye classic aliases sudo to fucking

I was trying to build a simple 2D (drag the fish to eat other fish) game in JavaScript, cause why not there are already many libraries i will certainly find one for my use.

I'm already familiar with p5.js thanks to Daniel Shiffman and his coding train sessions.

I thought to build the game with p5.js with the play and 2Dcollide libraries, but it turns out they don't have a custom irregular sprite collision detection neither the other thousands libraries which are rotting on github.

Guess, I need to build somethig own my own.

And I also hate it, cause I have to design those fishes, the main game logic, this collision detection function and levels

I need a coffee with a coding partner

I just hate trends...
A few years ago, if a website would show customized content (like news, posts) we would say that the job is done by a robot, scripts, filters...
Now days is AI this, AI that... Buy this bike, it as collision sensors so it's AI powered... New washing machine with inteligent AI.. You don't have to set half or full load because the AI will do that for you...

lol started using unity a couple of days ago and with the tutorials and everything it was all going merry and well. I followed the roll a ball tutorial word by word and letter by letter. the game worked perfectly, well....
at least in unity.
Thing is, I build the game and boom.
I have a working game with no collision detection(basically not working). didn't touch unity for 4 days now. Fuck I hate when this happens.

Accidentally avoiding all collision detection...

this has been a rollercoaster but damn it's looking decent so far. Next is trying to further speed things up using Cython! (owait no, MicroPeni$ paywalled me from Visual Studio fucking 2010)

Just realised - even if I are usually on collision course with central IT they save me a whole lot of "can you help me with this?" by not letting us do anything ourselves. Printers, new software, settings, startpages, drivers, browsers etc. Everything has to go through them.

Add the fact that the last Windows machine I've had was a P4 when XP came out and I'm in the clear for a whole lot of helping out. "Sorry but I only use Debian and OS X, but you could ask our IT people" :)

If one of these fucking deformable object simulations would actually do contact and collision right, that'd be greeeeeeeeeeeeeeeeeeeeeeeeeat.
😐

How am I supposed to grab the shit with a robot gripper, if shit doesn't do contact friction right? Gah!

Storing unique v4 uuids in db, collision detect or not?

When you used a whole Day to make a Ball kill a player, and All you had to do, was to allow collision while simulating physics.. Damn i stared myself blind on that shit!

I have to build a database migration that generates user handles. The user handles are unique within an organization. The user can change them. The auto generated handles are either the first name + last name, or the business name depending on which user type it is. Unless it would be a duplicate. Duplicates auto increment if the handle is taken. The character limit for a user handle is the same length as first name plus last name so I have to check for possible overflow if I add digits. I also have to see if the generated name is in the DB already because a user could have custom entered the result of the auto generation.

This has to be programmed async. The DB driver is using a transaction but multiple calls have to be made to check if the generated handle exists for that organization. Also I have to check the migration script itself for possible duplicates. 3/4 of the users have a handle and with the scale there will definitely be duplicate names.

My idea is if there is a collision, use a UUID and let the users pick something nicer next time they log in. Business says “Reeeeeee!!!! The users shouldn’t see a UUID!!! You can do this!!!” Absurd uniqueness requirements. Absurd backfill procedure. Absurd business rules.

- C-Suite: What the fuck this is not at all what I needed!! My whole company is on collision course with a liquidity crisis. You fucking idiot what did you do I’m so stressed oh noo
- This twat: I don’t ask questions to not stress you out

So when installing an rpm there is a file collision check. When you add a file to an rpm package with cmake / cpack it unfortunately adds parent directories your file goes into, which will give you conflicts with other packages. But well you have that beautiful feature to exclude directories from being added:
CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
Now somehow it failed. Turned out it would not work if my path ended with a backslash. Brush my banana! Like "/etc/sysctl.d" is a different animal than "/etc/systclt.d/". - But at least that's nothing against the strangeness of the "mv" command in those respects.

How much of "unique" the string that is the current epoch in milliseconds converted to base 36 ?
I know it is not universal. But require such a bad luck to have collision no ?
I am gonna use it for "transaction" primary key. (Every time a user pay, it it a new trasantion).
Uuid are very long, i need to put this pk in qr-code later
Thoughts ?
