Question

Extension Talk

Answer 1

@ikram002p Heres the post xD

Answer 2

ok start , why its more flexible/fast than before ?

Answer 3

Anchient chinese secret XD

Answer 4

But in all seriousness, First off i optimized various JS (not all, still have LOTS of work to do)

Answer 5

come on i thought it would be open source extension xD

Answer 6

I then fixed some CSS errors that where just repetitive causing unneeded CPU stress

Answer 7

Its not

Answer 8

about 80% of the extension is server side lel

Answer 9

only 20% is the JS and CSS x'D

Answer 10

This helps relieve lag from the extension greatly as well xD

Answer 11

Also i optimized various JSON Data... So that helps.

Answer 12

There's other things i still need to do though xD

Answer 13

yeah, also adding it to chrome was fast i thought its external server

Answer 14

Theres litterally basically Nothing in the extension, its just a JS command pulling in the scripts from my server... or rather leading to a assets file leading to all the files

Answer 15

http://ultrilliam.com/openstudy-enhancment/test-1/savedata.php This is the user save data string... Which soon will replace looking through a bunch of files for everything (server side scripts)

Answer 16

It will only display data from the user currently logged in

Answer 17

neat!

Answer 18

the encryption mechanism as well as loading a specific key to login a user was a pain...
This way nobody could cheat the system logging into another user... you physically have to login as a user on os for it to work... That in itself was hell to do... xD

Answer 19

i didn't know that os have such cute bug xD

Answer 20

anyway gtg now. again nice work Bravo.

keep the question open so people would ask u more.

Answer 21

Will do :p

Answer 22

@TheSmartOne @Nnesha @pooja195 @AlexandervonHumboldt2 @GreenCat This would be the place to ask questions, or suggest, things about the extension... Etc Etc

Answer 23

Thanks

Answer 24

I think todays project will be the desktop notifications making a return and being configurable... :P

Answer 25

Interesting, :)

Answer 26

Answer 57

give memy a back >_>

Answer 58

give what now back? O-o

Answer 59

OH

Answer 60

Sorry, it was causing errors cause your user wasnt defined on page load... Sozzry xD

Answer 61

Just annoying... Not really harmfull errors ._. (annoying as in taking up console room... LOL)

Answer 62

Actually the extension causes more CPU stress, injection is costly. Plus loading from remote rather than local is also damaging. It adds the need for an extra DNS resolve.

Answer 63

^True, this is why i actually only inject a script to add a <script> tag, then it adds the other various <script> tags, so it loads as though it was the normal os document...
it adds minimum stress, which is what allowed me to achieve higher speed, I then added the various bug fixes and client side script errors to speed the normal OS up. :P

Answer 64

Im glad theres someone else here who has knowledge xD

Answer 65

@Jaynator495 Chrome has some really good profiling tools, you may actually want to profile your extension.

Answer 66

Alright, done... What i came up with was my extension uses 20-50 (tops)mb of memory... and hardly any CPU (2%-10% max on a celeron dual core @1.50Ghz)..
I'm careful about adding new features and take into account how much lag they may cause.

if my extension never lost memory usage, and would only go up, in 7.5 minutes it would use 200mb-1gig(tops) of memory.
This is of course because of the JQuery in the beginning used to append everything, meaning when eventually i get to implement my extension side by side with OpenStudy everything will be located where it should, and use much much less. (assuming i'm the one that gets to add it and not OS!)

However openstudy in 7.5 mins if it didn't stop using memory, (as in it never lost any memory usage and just kept going up) will use 128 GIGS of memory... HOLY CRAP...
110GB-127GB from KnockOut events! WOW...

And this is why i need to fix OS so it no longer uses knockout! or at least update it where maybe it uses less memory, don't know haven't looked into it xD

Answer 67

WHOOPS I GAVE THE WRONG LINK!

Answer 68

@pooja195 's post i cant😂😂the phone the phone is ringing!

Answer 69

I thought i was on my extension pot XD

Answer 70

so what is this?

Answer 71

@Jaynator495 your extension initializes at 42307 kB for me, on initial page loads the CPU usage spikes to 100% which can induce tab hangs. If you are certain on going this route use RequireJS which would likely fix and accomplish what you want to do.

My primary beef with it is it requires downloads from a web server, which is horribly slow on dial-up. (Yes, dial-up is still common.)

Another nit pick, you say:
> 128 GIGS
... lord almighty how much RAM does your computer have?

Answer 72

LOL, Jay has like a lot of computers ;p

Answer 73

But I know that doesn't mean the RAM adds up.

He'll just have to list how much he has on each one :P

Answer 74

@TheSmartOne one browser in use = one amount of RAM usage. You do not add it up.

Answer 75

I know :P

Doesn't download things infact! anything that is cached the next session is used in a fresh copy to prevent errors... mostly because ill update things, this will eventually change when it is implemented into OS.

and oh my god what processor are you using? O_o
OpenStudy ITSELF can only get up to 50% WITH the extension on a OLD LOW QUALITY celeron processor!


And lets see...
16gb in one
8gb in another
128gb in another
256gb in another (got bored, built a RAM/CPU machine XD... should really set it up as a server at some point)
4gb in 5...
2gb in 9...
1gb in 2 sitting in my hallway...
and 256mb in computers i dont know why arent yet in the trash...

Answer 77

> Doesn't download things infact!

It very much does, it downloads CSS, and JavaScript files off of your server last time I checked. HTTP transfers are downloads.

> anything that is cached the next session is used in a fresh copy to prevent errors... mostly because ill update things, this will eventually change when it is implemented into OS.

For performance reasons that is abhorrent. Not to mention completely breaks the policy of allowed extensions on the Chrome Store. https://groups.google.com/a/chromium.org/d/msg/chromium-extensions/cfM_rfRC9fM/-1mfK7HF7e8J

Setting aside the legal issues, DNS resolution, connecting to a remote server, etc all add overhead.

Currently on a Intel (R) Core (TM) i7-6700K (not mine classmates.)

No one of those machines have 128 GB? How do you know it will grow that big if none of your machines have that much RAM?

> and 256mb in computers i dont know why arent yet in the trash...
... because that would be wasteful.

1st, technically the download is not required... It executes first then caches the file.
I use a workaround to get a fresh copy each time, but since the download comes after the exacution, it in itself is not a download...
That is unless i misunderstand the system... Dont know, haven't looked to much into it...

Who reads terms and conditions anymore? xD

Well clearly you were lying about the 100% CPU, as that would then be impossible considering i cant even get it to 10% on a quad core i5 @3.00Ghz

None of the practical use machines anyway, typically im either on the 16GB (gaming computer, userd more for coding due to its speed)
or on a 4GB laptop.
And because the chrome profile tools tell you the total ram used, total ram used assuming no ram usage went away and it only piled up.

wastefull to throw a computer away that is stuck in windows ME? I hardly see how xD

You are brutally misrepresenting what HTTP transfers are considered as, see RFC 2616. Anyone seeing as you did not comment on the resolutions, I suppose you agree they do add overhead.

> Who reads terms and conditions anymore? xD

... seriously? You do realize OpenStudy has a very strict and ridge policy on following the Terms and Conditions.

> Well clearly you were lying about the 100% CPU, as that would then be impossible considering i cant even get it to 10% on a quad core i5 @3.00Ghz

Such a lame accusations, I cannot see why you would make it. Firstly I am talking about on initialization (each injection the CPU usage jumps), secondly it fully is rational for someone to hit 100% CPU usage on initialization, for instance when V8 uses both x87 registers, and SSE registers, expect register starvation. (I do this for regression testing stuff, other Chromium developers run builds like mine.)

> And because the chrome profile tools tell you the total ram used, total ram used assuming no ram usage went away and it only piled up.

It shows you added history of allocations true, but you can set it to show the working RAM. Not sure why you started listing your RAM.

> wastefull to throw a computer away that is stuck in windows ME? I hardly see how xD
256 MB of RAM is enough to run a version of Linux or *BSD. Maybe you do not see the good in OLPC, that is just me though. The main points of my posts are clear.

Answer 81

You win this round :P

Answer 82

but your point will be mute when/if this gets implemented side by side with OS...
Also...
```
function loadjscssfile(filename, filetype){
if (filetype=="js"){
var fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript")
fileref.setAttribute("src", filename)
}
else if (filetype=="css"){
var fileref=document.createElement("link")
fileref.setAttribute("rel", "stylesheet")
fileref.setAttribute("type", "text/css")
fileref.setAttribute("href", filename)
}
if (typeof fileref!="undefined")
document.getElementsByTagName("head")[0].appendChild(fileref)
}
```
I think thats better then using a library to load scripts

Answer 83

@Opcode Not sure if you saw this...

Answer 84

I am familiar with that style, you inject by passing stuff to loadjscssfile(). It has the downside of being synchronous.

Answer 85

I'm unfamiliar to why that is a downside? ._.
