So there it fucking goes.

Hi. I'm WillibertXXIV.
I'm not a programmer by trade; I have a more than fulltime job as a cook. As for the last year, I spent pretty much all my free time, overlapping my sleep time, to learn how to code.

All that so I can create a game that I started working on the same day I started my learning process. So far it's shit and it's going to stay that way for a long time. Only I can say this. It's my baby. It's fucking ugly and shit but it's mine.

Yesterday I broke it. I broke my baby. I don't know how it fucking happe. When I went to sleep I had a steady 175fps, nice realtime lightning and player / enemy that flowed like running water. I worked really hard to make that happened. Profiling, writing better code, profiling, etc. It's still not good, it's less shit.

I woke up, beautiful day. Not too warm, not too cold, that sweet spot right in the middle. Girlfriend already made the coffee. Perfect. Woke up, sat down to start my morning time work before going to my realjob and

BAM

Everything is shit, 20fps max. That one thing, gfx.waitforpresent, showing up in the profiler eating everything as the game run. Movements are now of stroboscopic nature. Light is still ok but what good does it do now fucking piece of shit. I'm not qualified enough for this shit.

Fuck,
Fuck this,
Fuck this shit,
Fuck this shit i'm out of here.

Just optimized a bottleneck function in a program down from 160ms to 3ms. First time I've ever used a profiler, and it feels awesome.

The other day, I customer of ours asked me to try to improve the performance of an application of his in a particular method. The method in question taking more than 5 minutes.
I took a look at what it did in the profiler, and it shocked me. More than 100k selects to the database, to retrieve 116 records...
I took a look at the code... Scores of selects in nested loops inside other nested loops inside of... That seemed normal to them...
At the end after we improved it's performance it took 3 seconds...
What shocks me the most is that the customer is a developer himself, really knowledgeable and has an order of magnitude more experience than I do. Am I too anti "worthless database round-trips"? Is that normal? :S

I'm so fucking done with net neutrality. the only ones who want it are verion, comcast, and other big isps.

fuck them.

this is fucking merica. nobody wants it, and this is a government designed for the people. I guess it only works in theory.

the talk about this has been fucking exhausting. how much clearer could it be?

how does it keep coming up? so much of the economy is online. why would congress want this? this should be a fucking fundamental right. no bs, just fast speeds everywhere. i hate all the isps thinking that because the world is so reliant on the internet, they control everything.

isps are a service. that's it.

they're not a profiler or advertiser, just a service.

and if that changes, I'll buy a bunch of flash drives and go offline.

bottom line, we should have privacy, neutrality, and a safe web. fuck those greedy bastards.

This is what happened today in our dayli:

Lead: We need to profile our software

Me: You can use the chrome devtools as remote profiler, even on prod, or make HAR files for later inspection.

Lead: Yeah but no that’s just collecting data on every tick, we need something like “has been called x times”

Me: Yeah but you can filt -

Lead: Yeah no, so back when I wrote code in Delphi...

Me: *oh god no not this again*

Lead: ... We could have clicked a button in our IDE and it would wrap the function call with the API call to profile that function ...

Me, to the secret dev group in slack: doesn’t a simple method decorator and node performance api help with that?

The people in the group: We had this topic last Friday all day...

Me: oh well *get’s coffee and ignores lead*

I despise it when software developers remove features because "too few people use them".

Is this what those shady telemetry features are for? So they can pick which useful features to get rid of because some computer rookies whined that it is "feature creep" rather than just ignoring it?

Now I have to fear losing useful (or at least occasionally convenient) features each time I upgrade, such as Firefox ditching RSS, FTP, and the ability to view individual cookies. The third can be done with an extension, but compatibility for it might be broken at some point, so we have to wait for someone to come up with a replacement.
Also, the performance analysis tool in the developer tools has been moved to an online service ("Firefox profiler"). I hope I don't need to explain the problems with that.

But perhaps the biggest plunge in functionality in web browser history was Opera version 15. That was when they ditched their native "Presto" browsing engine for Chromium/Blink, and in the process removed many features including the integrated session manager and page element counter.

The same applies to products such as smartphones. In the early 2010s, it was a given that a new smartphone should cover all the capabilities of its predecessors in its series, so users can upgrade without worrying a second that anything will be missing. But that blissful image was completely destroyed with the Galaxy S6. (There have been some minor feature removals before that, such as the radio and the three-level video recording bitrate adjustment on the S4, but that's nothing compared to what was removed with the S6.).

Whenever I update software to a new version or upgrade my smartphone, I would like it to become MORE capable, not LESS (and to hell with that "less is more" nonsense).

So I'm making a music game, and I've been struggling to fend off this large sound latency issue. There is like a ~80ms of latency, which is a total deal-breaker for music games.
So I've been polling everything using a profiler, but nothing came up... Until just now, I realized:
IS IT MY F*<KING KEYBOARD THAT IS LAGGING?

I pulled my iPhone out, opened the Notes app, and recorded the screen as I smacked the keyboard.

Whaddaya know, exactly after 5 frames (in 60fps) of the sound of me punching the keyboard, the letter shows up.

Now I need to take *this* lag into account :facepalm:

0 bytes of heap allocated per cycle! Figuring out the Unity profiler actually helped me improve my C# optimization. <3

Figured out the root cause of slow code by using a profiler in an afternoon (more like an hour but needed to confirm/investigate)...

Team spent over a week trying to figure it out using logging and debugging...

Even after I told them to use a profiler...

Guess now I've justified my position of being the highest paid dev on the team.

I just know how to use other tools besides a hammer.

I need to performance monitor our web app. I have been working on some speed improvments since some of our customers have complained. My boss wants me to be able to produce stats which he can use (and abuse) to highlight to customers that we have got quicker. I am currently looking at blackfire for PHP profiling to help with speeding things up but I need a top site overview for everything. Our stack is PHP (no framework), JS (jquery + vanilla), MySQL on Windows mainly. On premise solutions would be good since we don't traditionally run in the Cloud. Our system isn't SaaS and is installed on dedicated data centre servers or on premise

## Scripting myself out of the company

who needs an expensive profiler, when you can make thread dumps and compile them into a flamegraph for free without any risk of outages!

Though what bothers me is that I'm yet to come across a person in this company who knows how to read them (besides me)...

Are flamegraphs really THAT unpopular?

I mean.. you can represent the whole profile in a single image!

I have discovered the power of YourKit. Really helped me track down the problem of a ton of threads and a slow application.

Long story...
I'm a junior-ish dev (worked 3 year part time in a small company)
I've been assigned the happy task of doing some performance profiling on our windows application to see where we can work to make the app run smoother.

Visual studio profiler keeps crashing when generating the report when I do CPU sampling.
I'm a very unhappy Dev right now.

Java's garbage collector must be broken - it failed to get rid of this dumpster fire another dev called "source code". But, hey, at least the profiler works.

Don't ever give you work mail when you create an account to download a profiler , that decision is chasing me for the last 4 years , stalking saleswoman even came to the office without letting us know and nowadays I get freak mails from them

Bloody fucking Android! Updates, updates and more updates! My development Nexus 5X won't allow me to sideload apps since it updated... Hello, printf debugging! Goodbye, profiler and debugger!

My hate for Android grows with each version after 4.0.$something... 2 was shit, I missed 3, 4 was OK, and since then it's going steeply down.

And don't get me started on Material Design...! Good luck figuring out what's a button and what's a label...

And what's up with the "let's keep all apps running all the time to save a few ms on start" philosophy!? Who thought that is a good idea!? Yeah, System.exit(0) works, but... Is it so hard to determine when it's not needed anymore (has no services running etc.)? Why should a web browser (for example) stay in memory after I quit? Minimize is a thing (Home button), why make it so confusing?

Another thing - feedback-less async tasks - why? I like to know when it is working in the background... How the hell am I supposed to find out if it is supposed to do this or if it is frozen?

And Android deciding to kill your process whenever it pleases without any callback... Happened to me once with an Activity in the foreground (no exceptions anywhere in my app, it just quit). How do you do IO properly? It seems you can't guarantee some file or socket or something that must be closed doesn't stay open (requiring to restart Bluetooth 'cause the socket wasn't closed, for example)...

That feeling you get when all seems well and you've been running your application in production for months, only to learn it's been soaking up memory like a sponge and frequently paging the ops team after hours...

Thanks to Google for at least keeping the local performance analysis tool in the Chrome developer tools.

Firefox Profiler is a joke.

Had a watchdogs type dream, but my profiler kept bugging up and I ended up in the bunker trying to fix it until I woke up. I no longer play that game
