So I'm working on a computer vision project that grabs video from my webcam and detects faces in each frame. Earlier yesterday morning I was capping out at 30 frames per second, which is what I believe to be the max for my webcam. As the day became night and I was wrapping up my work on a portion of the project, I noticed that my newly compiled version was only getting around 8 frames per second. Confused, I looked into my frame grabbing + face detection code.
"Maybe I can only detect faces in a certain region of the image, based on where the face was in the previous image?" No, still 8fps. Hmm.
"How about I lower the resolution of the image, that would definitely help!" I tried that, but no speed boost came either. What??
I start to dig deeper. Maybe I'm not linking my libraries correctly, and it's using an older library I compiled. So I recompile that. Nothing.
"Am I low on resources?" I close out of all my other apps. Nothing.
Okay, wtf. Now I just comment out the face detection code entirely, and only grab webcam frames.
8fps. ?????
Suddenly, I get an idea. I get out of my desk, walk over to the doorway of my room, and flip the light on. I sit back down, and run my code.
30fps.
The stupid webcam switches to "night mode" when it detects low light, which restricts its ability to output frames at high speed and caps at 8fps. Damn, I felt like a fool 😂5 -
How priorities work #1
High priority : Client request to change button color to red
Low priority : improvement that will boost product's speed and robustness6 -
My last phone with keyboard, bought not so long ago. I miss ssh to my srv over a phone sometimes. But I do not miss hacking android to move graphic memory to standard memory to boost Os speed...

Cisco.
It’s a prime example of “Don’t get attached to the company just because of one thing.” I have three of their routers that I bought used. WRT160N, WRT310N, and WRT610N. They all looked aesthetically pleasing and I thought all would be fine and dandy. Until I got a internet boost. Going from 12/1.5 up/down to 250/25 up/down.
HOWEVER, MY ROUTERS CANNOT REACH EVEN HALF THE SPEED DOWN.
Best part was when I called, they said that they couldn’t fix it because of one thing that all the routers have in common.
Legacy.
I’ve tried dd-wrt all with no luck. And they have the audacity to recommend another product of theirs?!?17 -
I fucking love it!
After a full day of refactoring old shitty code into a glamorously sparkling epicness of bytes, the whole thing worked flawlessly and on speed.
Quite satisfactory. 😊
Templating in TWIG, especially using inheritance and includes, is so much more fun than doing it in raw PHP!

Guys, we need talk raw performance for a second.
Fair disclaimer - if you are for some reason intel worker, you may feel offended.
I have one fucking question.
What's the point of fucking ultra-low-power-extreme-potato CPUs like intel atoms?
Okay, okay. Power usage. Sure. So that's one.
Now tell me, why in the fucking world anyone would prefer to wait 5-10 times more for same action to happen while indeed consuming also 5-10 times less power?
Can't you just tune down "big" core and call it a day? It would be around.. a fuckton faster. I have my i7-7820HK cpu and if I dial it back to 1.2Ghz my WINDOWS with around lot of background tasks machine works fucking faster than atom-powered freaking LUBUNTU that has only firefox open.
tested i7-7820hk vs atom-x5-z8350.
opening new tab and navigating to google took on my i7 machine a under 1 second, and atom took almost 1.5 second. While having higher clock (turbo boost)
Guys, 7820hk dialled down to 1.2 ghz; 0.81v
Seriously.
I felt everything was lagging. but OS was much more responsive than atom machine...
What the fuck, Intel. It's pointless. I think I'm not only one who would gladly pay a little bit more for such difference.
i7 had clear disadvantages here, linux vs windows, clear background vs quite a few processes in background, and it had higher f***ng clock speed.
TL;DR
Intel atom processors use less power but waste a lot of time, while a little bit more power used on bigger cpu would complete task faster, thus atoms are just plain pointless garbage.
PS.
Tested in frustration at work, apparently they bought 3 craptops for presentations or some shit like that and they have mental problems becouse cheapest shit on market is more shitty than they anticipated ;-;
fucking seriously ;-;16 -
Not bad for a test over WiFi 😮
Still, how I long for fiber... Then I won't need to use a VPN to boost my speed lol... Not that I'll stop using one...

Im tasked to investigate a stored proc that is slow at certain times ( 20-30mins ) and fast at other times ( 10-15 secs ).
After following suggestions i found out that adding NOLOCK hint on all the select queries makes the execution time fast ( 10-20 secs) .
Although i know that adding NOLOCK means a dirty read of possible incorrect data, does it justify the performance boost?
Speed or data correctness?4 -
I just released version 2.0 of my UI package.
Laravel Livewire & Bootstrap 5 UI starter kit. This package is a modernized version of the old laravel/ui package for developers who prefer using Bootstrap 5 and full page Livewire components to build their projects. It also comes with a few features to boost your development speed even more.
