Sometimes I just don't know what to say anymore

I'm working on my engine and I really wanna push high triangle counts. I'm doing a pretty cool technique called visibility rendering and it's great because it kind of balances out some known causes of bad performance on GPUs (namely that pixels are always rasterized in quads, which is especially bad for small triangles)

So then I come across this post https://tellusim.com/compute-raster... which shows some fantastic results and just for the fun of it I implement it. Like not optimized or anything just a quick and dirty toy demo to see what sort of performance I can get

... I just don't know what to say. Using actual hardware accelerated rasterization, which GPUs are literally designed to be good at, I render about 37 million triangles in 3.6 ms. Eh, fine but not great. Then I implement this guys unoptimized(!) software rasterizer and I render the same scene in 0.5 ms?!

IT'S LITERALLY A COMPUTE SHADER. I rasterize the triangles manually IN SOFTWARE and write them out with 64-bit atomic image stores. HOW IS THIS FASTER THAN ACTUAL HARDWARE!???
AND BY LIKE A ORDER OF MAGNITUDE AT THAT???

Like I even tried doing some optimizations like backface cone culling on the meshlets, but doing that makes it slower. HOW. Im rendering 37 million triangles without ANY fancy tricks. No hi-z depth culling which a GPU would normally do. No backface culling which a GPU with normally do. Not even damn clipping of triangles. I render ALL of them ALL the time. At 0.5 ms

Today I discovered that we have a CSV export button for an order transaction system, on a page which is completely disconnected from the rest of the website.

It is only being called by an internal server, used by our Data department.

They run selenium to click the button.

Then they import the CSV into a database.

That database is accessed by an admin panel.

That admin panel has an excel export button.

Which is clicked by our CFO. But he got bored of clicking, so he uses IFTTT to schedule a download of the XLS and import it in Google Sheets.

That sheet uses a Salesforce data connector.

Marketing then sends email campaigns based on that Salesforce data...

I've been doing interview prep for almost two months now (off and on). Doing this course online to better understand algorithms and doing Leetcode problems here and there. Definitely not putting in 6 or even 8 hours a day into studying since I'm working, but fuck I feel so discouraged when I'm not even able to get an "easy" problem.

I really want to get better, and I know it takes a lot of patient and practice when it comes to problems. I try my best to tell myself "you haven't learned this yet" or "you'll get it soon", but in the end I just feel so discouraged that I want to quit practicing for interviews.

I hate that this profession requires people to spend X months or even years studying for an interview. That the 3-5 years of relative and good work experience means nothing more than passing a resume screening to get to a coding interview where they ask you a problem you'll never face in your career at X company.

Do I hate the process because I'm just bad at algorithms I don't use often? Or would I feel like it's just and fair if I understood things easier and were able to land jobs easily because I get all the algorithms?

I just want to be better.

That's not an ERROR. That's a SUCCESS.

My team now does daily mini-standups: what you did, what you will do, what's blocking u

But with this wfh, I feel like slacking more or just seen to have less critical work to do... but not sure if the other guys are just "padding their list" or actually really busy.

So wondering when I have nothing to do for work/no defined deadlines or deliverables... How do you look busy?

I do have a lot of optional tech debt improvement work I could do but basically these are like backlog... And not really fun.

Developers have given semicolons a lot of power

The app I worked on is going for production into 36 sites starting from tomorrow.
Wish me luck.

Okay guys, this is it!

Today was my final day at my current employer. I am on vacation next week, and will return to my previous employer on January the 2nd.

So I am going back to full time C/C++ coding on Linux. My machines will, once again, all have Gentoo Linux on them, while the servers run Debian. (Or Devuan if I can help it.)

----------------------------------------------------------------

So what have I learned in my 15 months stint as a C++ Qt5 developer on Windows 10 using Visual Studio 2017?

1. VS2017 is the best ever.
Although I am a Linux guy, I have owned all Visual C++/Studio versions since Visual C++ 6 (1999) - if only to use for cross-platform projects in a Windows VM.

2. I love Qt5, even on Windows!
And QtDesigner is a far better tool than I thought. On Linux I rarely had to design GUIs, so I was happily surprised.

3. GUI apps are always inferior to CLI.
Whenever a collegue of mine and me had worked on the same parts in the same libraries, and hit the inevitable merge conflict resolving session, we played a game: Who would push first? Him, with TortoiseGit and BeyondCompare? Or me, with MinTTY and kdiff3?
Surprise! I always won! 😁

4. Only shortly into Application Development for Windows with Visual Studio, I started to miss the fun it is to code on Linux for Linux.
No matter how much I like VS2017, I really miss Code::Blocks!

5. Big software suites (2,792 files) are interesting, but I prefer libraries and frameworks to work on.

----------------------------------------------------------------

For future reference, I'll answer a possible question I may have in the future about Windows 10: What did I use to mod/pimp it?

6. Kate
Enhanced text editor I like a lot more than notepad++. Aaaand it has a "vim-mode". 👍
https://kate-editor.org/

7. kdiff3
Three way diff viewer, that can resolve most merge conflicts on its own. Its keyboard shortcuts (ctrl-1|2|3 ; ctrl-PgDn) let you fly through your files.
http://kdiff3.sourceforge.net/

8. Link Shell Extensions
Support hard links, symbolic links, junctions and much more right from the explorer via right-click-menu.

9. Rainmeter
Neither as beautiful as Conky, nor as easy to configure or flexible. But it does its job.
https://www.rainmeter.net/

10 WinAeroTweaker

Of course this wasn't everything. I also pimped Visual Studio quite heavily. Sam question from my future self: What did I do?

1 AStyle Extension
https://marketplace.visualstudio.com/...

2 Better Comments
Simple patche to make different comment styles look different. Like obsolete ones being showed striked through, or important ones in bold red and such stuff.

No matter how much fun it will be to do full time Linux C/C++ coding, and reverse engineering of WORM file systems and proprietary containers and databases, the thing I am most looking forward to is quite mundane: I can do what the fuck I want!
Being stuck in a project? No problem, any of my own projects is just a 'git clone' away. (Or fetch/pull more likely... 😜)
Here I am leaving a place where gitlab.com, github.com and sourceforge.net are blocked.

But I will also miss my collegues here. I know it.
Well, part of the game I guess?

This week I started a new job.

My role changed from "Full-stack-web-developer-sysadmin-DBA-helpdesk-strange-person-fixing-stuff-around" to "Back-end Developer".

Moreover, it's a full remote position (so difficult to find in Italy!), so:
1. I can wake up 1.5 hours later;
2. I don't have to waste anymore 2 hours every fucking day driving in traffic to reach the workplace;
3. I can use my fucking bathroom;
4. I can drink hot tea in August without being criticized. 😀

I'm fucking happy!

Holy fuck this new GitHub feature is amazing!!!
It's called GitHub Actions and you can easy automate your work flow using a simple graphical editor!
I need to test this out right fucking now!

To all you fuckers out there giving bad app rating because some shit does not work on your shitty phone and you are to fucking lazy to report the bug via the fucking "send log to dev"-button that pops up with the exception.
Go fuck yourself.
And to all the user whose bugs I fixed and did not change their Bad rating - fuck you too.
And oh.. The fucktards that did not even install the app and give a Bad rating because i am your competitor - guess what...fuck you.

Are you even a dev if you haven't done this once?

My dad found a phone a few weeks ago and asked me what he should do with it. Knowing how much it hurts to lose personal data, I said I could try to find the owner and send it back.

My first attempt was to search through the files on the SD card in order to find an identifying document (CV, bill, address...) but there were only family pictures.

My second attempt was to unlock the phone and check the information about the owner and the accounts linked to it. But for this to be possible adb has to be enabled. Good thing is that that particular brand shows an option for activating adb on the recovery menu.

But then, it's Android Oreo and I haven't found a way to lift the lock pattern. I thought I could bruteforce it over the shell (as I found there could be about 1300 possibilities for 2 to 5 point patterns), but there is the same attempt throttling as on the screen so that would take ages.

Finally, I found the owner in the most "social" way : The phone was displaying the weather for a particular place. It turns out that there are only 3K inhabitants in that city, si I thought that a big enough Facebook group might help me find the owner. So I posted a message on a 500 people FB group dedicated to this city with a selfie of the owner : someone identified her within 20 minutes.

Mission accomplished 😎

If you see someone coding at mcdonalds, starbucks etc.

"Excuse me, would you like a fork for that spaghetti"

It's just me or?

Stackoverflow.

This couldn't be any truer, in our totally flawed education system.

I fucking hate CNET already. I mean who likes a website which autoplays a video everytime you visit them, with 200% volume.

But this time, I am just so fucking annoyed. Here is the title of an article:

"iPhone 8, X's wireless charging is a game changer for Android"

And the subtitle:

"When it comes to Apple, plenty of Android phone makers are monkey see, monkey do."

FUck you motherfucker. "Monkey see, monkey do". Are you fucking kidding me you cunt?

Remeber your 3D touch bullshit? Your fucking wireless charging will be bullshit too.

"the rest of the phone users make do with messy cables."

Maybe you're a fucking imbecile who doesn't know how to manage simple cables and ends up with broken wires.

You know who looks like a monkey? Some apple users who uses that shitty looking wireless earphone, which looks like monkey's dick you asshole.

Fuck off!

I think I have a crush on Kotlin 🙈

Every computer needs a “cleaning keyboard” mode where the keys would be inactive while you wipe them down

So, since I hear from a lot of people (on here and irl) that Linux has a 'very high learning curve', let me share my experiences with the first time my dad touched Linux (Elementary OS) without me interfering at all! (keep in mind that he is very a-technical)

*le me boots the system* (I already did setup a user account for him and gave him the password).

Dad: *enters password and presses enter*
Me: "Hmm that went faster than expected."
Dad: "Uhm I know how to login son, it's not that hard and pretty obvious".
Me: "Alright, why don't you try to open up the default word documents editor on here! I'll be right back!"
Me: *Goes away and returns after a minute*.
Dad: *already a few test sentences typed in LibreOffice writer* it's going pretty well :)!
Me: "Oo how did you find that?!"
Dad: "Well, there's a thingy that says 'applications' so I clicked in and found it in the "Office" section, do you think I am blind or something?!"
Me: 😐. uhm no but I just didn't think you'd find it that quickly. Now try to install Chromium browser! *thinking: he'll fail this one for sure* I'll be right back :).
Me: *returns again after a minute or so*
Dad: *already searching for stuff through Chromium*
Me: "wait, how the hell did you do that so quickly, it's not the easiest thingy for most people".
Dad: "Jesus, it's not that hard! I went to the application browsing thingy, typed 'software' and then a sorta software store icon showed up so I clicked it and it opened a windows with a search bar saying something like 'search for applications/software'. clicked in it, typed 'chromium', saw it coming up, there was a very clear 'install' button, it asked for my password, I put it in and after a little it gave a notification that it was installed. Then I went to that application browsing thingy again and typed Chromium. Then I hit enter because it selected an icon called chromium...."
Me: O.o. Okay this is going very good, now open an email client and login to your email address!
Dad: *goes to application browsing thingy, types 'email', evolution icon shows up, dad clicks it, email address setup steps show up and dad follows them quickly. After about a minute, everything is setup.

I expected this to be a hard process for someone who dealt with Windows his entire life but damn, I underestimated it.
Asked him if he found it easy/what he liked about it:
"Well, it's very clear where I can find everything, default browser/email/word document editor programs are easy to find and that's about all I need so yeah, great system!"

I am proud of you, dad!

When you are so incompetent your senior gives up and writes your code for you

fuck you Java

Typical Google! :P

10 years ago, I found a vulnerability in the connection between an insurer I was working for, and the network of databases of municipalities. I was only a hacker in so far as kids who watched Hak5 are considered hackers, so I always carried this laptop with a fake access point, package sniffer, wep crack, sslstrip, etc with me.

The vulnerabilities allowed me to register a new identity, for which I requested a passport.

Walking up to the town hall desk with two passports with different names, both mine, was pretty cool.

I did not do anything malicious, and was hired to fix the issues (wep encryption on insurers trusted wifi, and municipality postgres gave write access to all third parties)

For a few days I was the coolest kid in school though!

7 am. Dog wants out. I roll out of bed after trying to pretend I am dead.

Walk down the stairs to the side door. Half asleep and notice that the door has daylight shining through on the lock side. Didn't shut it all the way the night before. Walk outside. Dog does his thing. Turn around. Doors locked.

Fuck.

Go for my phone. In the house. Go for my keys. In the house. Fuck. Fuck a duck.

Start checking my windows. One opens a fraction of an inch. Doesn't do me any good. Dog is outside with me. Freezing his ass off. It's like 5 degrees here.

Both of my neighbors don't answer their door. Life flashes before my eyes. Put my dog in my jacket to warm him up. Little 15lb rat terrier. Not made for snow.

He's fine for now. I grab a piece of rebar from my backyard and lever my window a bit more open, busting one of the locks.

And then I yell "ALEXA. OPEN THE FRONT DOOR." The voice of an angel responds. "OK." Whirrr. Click. Door opens. Sweet warmth.

I need a fake rock with a key under it.

Great Sunday.

Tips for backend developers

!geek girlfriend

Me and my partner are in the car driving. We drive by a young girl who is on her scooter. I look at my gf and ask,

Me: do you sometimes have some weird thoughts in mind (and nothing relating to sex her just so you know).

Her: well what do you mean?

Me: well i se that person scootering on the sidewalk and i imagine screaming at her like a lunatic “GET THE FUCK OFF THE ROAD PUNK” (which the little girl clearly isn't).

She laughs.

Her: yeah，i do too but it's more scientific， like sometimes i wonder how many times some one would flip. In the air if i hit them with the car or how long would it take some one to reach the ground if i pushed them off the balcony.

....

Me: silence...

Skin goes white

Her: looks at me with a big smile!!!

Im not sure if this is good or bad ;)
