[Moto X Q&A] insanitybit:
I saw the two kernels listed in the 'kernel' section - both use -O3 optimization, as opposed to the default -O2.

For those who don't know, -O2 is used by the stable Linux kernel. It is used for a reason - -O3 optimizations can significantly increase the size of the executable code with the benefit being slightly faster code (ex: loop unrolling increases code size but removes iterator). A larger binary is more difficult to cache.

This is why in *many* cases a -O3 kernel is *slower* than a -O2 or even a -Os kernel, and this goes for many programs.

So, I'm curious, anyone actually benchmarked? Any kernel devs looked at the size difference in -O2 compiled kernels and -O3's?

It would be very interesting to know, because I've seen such mixed results myself when optimizing code using -O3.
[Moto X Q&A] DJLamontagneIII:
I've been testing -Ofast and -O3 for a wile with my kernels and I would say ive seen most performance gains in benchmarks and real life scenarios from the ROM being compiled with higher optimization than the kernel but there is a slight performance bump with the kernel being compiled with -O3/-Ofast. I have seen older weaker devices with low memory be somewhat counterproductive with the increased size so I would drop it down to -Os which would turn off all the flags that increase size than I'd add some flags that would be on by default under -O3. Really its all the fun of it tho you can experiment a bit figure out some of the flags that are enabled under -03 that are causing issues and turn them off. You can find some info on the different flags here http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html... http://www.linaro.org/blog/android-...aro-android-2011-10-and-future-optimizations/.

[Xperia SP General] QBerto:
1. There's no need to change kernel to root

2. U can't install custom kernel with locked bootloader,u're ure giving instructions to brick phones

3. There's no need for towelroot to have internet acces to work

4. And talking about Towelroot, there's a thread with towelroot in this forum (about three actually)

5. There are recoveries for locked booleaders, also there's an index with it in general

5. What with all ad f.ly and ad links? are u trying to make money? put a link to the original thread or the links of creators if is not your work

6. Red is a really bad color to be the main in the thread

just sayin'
[Xperia SP General] Tech N You:
Apologies on first part for letting adfly links on the tutorial wasn't aware of this rule.

Secondly towelroot gave error on my Xperia SP that "Please make sure you are connected to internet" that's why I advised to stay connected likewise SuperSU would take Internet connetion to download then why not to be on safe side :)

As considered with that custom kernel flashing thing thank you for correcting me! You saved a blunder mishap and prevented it from happening thanks a LOT!:highfive::cool::angel:

I always give credits to the one who created the original stuff! I NEVER TAKE CREDITS FOR OTHER'S WORK

And RED is a color that is easily hilighted and people actually pay more attention to words written in red rather than any other color :eek::p

Just Saying:D
[Xperia SP General] QBerto:
:good:

Wut? Towelroot now needs internet conection? D: maybe sounds paranoic, but don't like xD

and one more thing, you can install SU from the zip w/o recovery, just open the zip with a file manager and look into 'common' folder, there's a Superuser.apk in there, install as normal APK, and you can update binaries with the zip w/o internet too (just open SU app and click normal, the same as you said)
[Xperia SP General] Tech N You:
As for being paranoic check this out http://www.shadowandy.net/2014/06/geohots-towelroot-features-one-click-root-many-kitkat-devices.htm and read cooment of guy named Alin guess I am not the only one facing this issue :rolleyes:

As far as SU is considered I told both the method stop daydreaming and check the post clearly :p

[ONE Q&A, Help & Troubleshooting] gwimmel:
Hey, so i recently tried Retroarch on this phone and noticed some stuttering in everything i try to play with it, i then looked through the settings and apparently the OS reported refresh rate said it was 63Hz, I then tried the calibrate refresh rate option and that said it was 63.4Hz. I've tested this on several other apps/games as well that have a locked framerate, and to my dismay, they also stuttered about 3 frames every second.

This is a pretty major issue for me, because everything looks and feels very unpolished and it's distracting to me. What i wanna know is, if it's possible to force feed the display 60Hz, and if the display would even handle it properly without any doubling or skipping of frames. If any of you have a solution for this, I would be very grateful.

Thanks.
[ONE Q&A, Help & Troubleshooting] tj11112129:
I'm having this same issue with my phone as well, and it even effects flappy bird. I know its not the most serious issue in the world but for games that require fluid motion and somewhat precise timing, such as emulators or flappy bird, its enough to make me stop wanting to play the games altogether. Does anyone know why the phone (Oneplus One) runs at 63hz and is there any way to change it or somehow fix the issue with video stuttering in apps on phones that run at uneven refresh rates, such as 56hz, 59hz, or 63hz?
[ONE Q&A, Help & Troubleshooting] JTC3:
Did you ever find a fix? Everything on the phone is flawless, its just the stuttering is the only thing bugging me!! :mad:
[Sony Smartwatch] julz:
Hi, as you may know my Google developer account has been suspended. I have lodged appeals to have Google reconsider their decision but they have failed to respond. This is not uncommon for them and is quite disappointing. A petition has already been started by another developer to get Google to treat developers more fairly. If you would like to show your support, please sign up on the link below. For every 10 sign ups via my link below, I will make one of my watchfaces available for free to download. I had just created over 10 new watchfaces when my account was shut down.

Many thanks for your support!

Petition link:

http://www.change.org/p/sergey-brin..._medium=email&utm_campaign=mailto_link_mobile
[Sony Smartwatch] gandalf_grey91:
No problem, signed the petition straight away. Its a pleasure to support you, even in such a small way. Thanks for all the hardwork. I have enjoyed using your watchfaces. Really sorry about what Google have done. You kind of get the feeling that devs working on Android Wear will not suffer the same treatment.

Although new watchfaces would be nice, I have lost all of your free-to-download watchfaces from Play store, when I flashed the KK 4.4.4 update for my phone. Any chance you could upload them somewhere and make those available for download?
[Sony Smartwatch] julz:
Thanks mate!

Guess what... as of about 60 seconds ago Google has decided to reinstate my account! I will be selectively republishing my watchfaces - only those that are original designs though just to be safe.

My offer to release a free watchface for every 10 petition signatures still stands though and I will release them here free when each target is met. The watchfaces will still be available to purchase via Google Play (once I'm set up again).
[Sony Smartwatch] gandalf_grey91:
Thats great. Glad to hear google saw sense.
[Sony Smartwatch] kill_dano:
post your watches on the amazon market. That's why competition is good.
[Sony Smartwatch] julz:
Hi, yes this is something I've started the process of doing but will hold off now as my google account is back online. Unfortunately the time and effort spent publishing to amazon takes time away from actually designing new watchfaces. It takes me about 15-20 mins per app to get it prepared and listed on amazon or google as I need to do the graphics for each.
[Sony Smartwatch] enigma_x:
I think the reason to close the account in the first place was due to the violation brands name/designs. I warned about this in some post and put a link to the page which had alot of information for developers/designers what they need to know when designing something that already exists. But cant find that post anymore. Hmmm... Odd... Anyway, the problem is mostly that people uses other designs/part of the designs or brand name as part of their own designs. Just checked Play store and it seems to be that they removed those watchfaces violating other brands like Rolex etc. Am I right?

[Sony Smartwatch] julz:
Thanks for this. Yes it was although what finally triggered my account suspension was based on an incorrect ruling. That is why I was able to get my account back and took precautions to prevent further issues by removing all my other watchfaces that were a potential risk.

Thanks for the links, I'll have a look into them for future reference.

Think that it was actually better that Google did something than any of those companies demanding their legal rights. It might have been nasty situation.

Yes, exactly right... I had already started to make modifications such as removing logos but I think it is safer just to remove them all and start with my own designs.
[Kindle Fire Q&A, Help & Troubleshooting] jimmybob123:
Hi,

I installed the newest OtterX ROM on my Kindle Fire 1st gen and then was notified of a CM update. So i downloaded and installed the update. When I rebooted its gives me an error message of "Encryption unsuccessful" and reset tablet. Every time I reset the tablet it gives me the same "Encryption unsuccessful..." message. So I got pissed off and wiped everything from the kindle fire and tried to reinstall but lo and behold I lost all my flashable zips from on my /sdcard folder!! Duh!!

I use Mac OsX and whenever I goto the terminal to run adb, it doesn't list my device (I'm booted into recovery TWRP 2.7.0.0 btw). I'm stuck and can't flash or push any zip files to my kindle fire now, because dab doesn't list my device. BTW, dab has successfully worked on this device previous to loading the new CM update. I can't mount the USB drive from TWRP either with OtterX.

How can I get my Fire to work again???

Thank you!!
