Google is unvailing its chromebook. (Yeah another piece of tecnology to help google reach its goal of World Domination)
Its said to boot in 8 seconds, eliminates backups and updates, and will Replace(kill) Windows.
What Do you think About It?
Also offtopic on my offtopic thread but will XDA support HDTVs that are web connected. Meaning will there be any developement.?
Most people have never heard of cloud computing so i predict a slow adoption rate and a very, very small market share.
Mine showed up totally unexpected yesterday. It's fast and different. Rooting is done by a switch near the battery. Comes with 100 mb (verizon) free for 2 years. However, got it working with AT&T today.
Would love it to be compatible with Android apps, however, it can be dual booted with Android or most any other OS.

You got an actual chromebook?! I'm assuming not a CR-48 as that was all supposed to be done ... and I keep hearing June 15th or whenever for the official ones ... ?
I'm exited to get my hands on one. I love my little CR-48 but it can be as slow as an old dog. The latest updates have really helped though, I notice the time it takes to reconnect to WiFi after sleep has been cut in half, if not more. I just think the single core kind of holds it back for the most part. Not a whole lot of difference from some of the newer specs I had seen, but apparently they are quite speedy. A dual core will do that, considering the OS itself is so lite - such a minor bump would obviously result in a pretty drastic performance boost.
The update with a more 'official' file manager and media playback was nice to see, if not late.
I'll never be pulled from my desktop, or even more proper notebooks, but the Chrome OS angle is definitely a neat and handy one at that. In terms of practicality, some things just aren't the same / comparable.
And I think the cloud term sort of swings people for a loop ... the cloud is essentially the internet. Obviously. I just think the term results in people over-thinking it. When you explain it like that people seem to 'get it' more.
As best as I can tell it's the CR-48. It has a codename of Mario. Non branded.
Cloud computing is a different paradigm than traditional. However with Dropbox, box.net and Sky drive, I have about 40gb of storage available.
There are some interesting sites on the web about Chromebook. The facinating (but somewhat confusing) thing about the entire concept is the lack of a "desktop". Running everything from a browser is clunky.
I am going to re-check my CB to see what it's packed with.
I was pleased that I can use my AT&T sim and that I am not married the Verizon. Would love to use as a phone... better yet, will be trying to dual boot Android to use the apps available.

Yeah sounds like a CR-48. Lucky guy, heard they ended shipment a while ago. I love the look of the unbranded notebook myself, totally sleek and totally sexy.
Finding workarounds for most tasks can be a little overwhelming, but once you spend some time looking around you get some good suggestions from people on what may be a good method / alternative.
I like the idea myself, a lite and speedy OS that doesn't require 'protection,' fast boots and returns from sleep at an amazing rate and also not having all sorts of **** shoved down your throat.
It's obviously not going to be a legitimate replacement for all, but as a secondary notebook it can hold its own. And for those that have netbooks for simple and not so demanding tasks, this could easily replace their devices. 'Cloud computing' isn't as complicated, or daunting, as some want to make it out to be.
Just another option for the people, and something I could see being pretty successful for a select group / market share.

Google released a bad update, I don't know why people yell at others for being upset. We didn't see threads like this at all for 4.11 or 4.12. Its obvious that Google obviously needs to work on this as people don't post threads like this for no reason.

I have almost only good experiences with the 4.2, generally feel more stable and haven't noticed any sluggish behaviour. Only problem Im having is with bluetooth, it won't remember profile selections for my paired devices. So everytime I connect to my phone for internet access I need to go and tick internet access under profiles
Sent from my Galaxy Nexus
The majority of people come here for solid technical advice, and some of this discussion hardly inspires confidence. We also need confidence in Google as we have invested in their product and it is perfectly legitimate to raise concerns about the 4.2 update that they pushed to our devices
If you use Bluetooth, for example to tether, then you will have been thrown by the changes to the interface. It was not obvious how to connect, and is actually quite inconsistent in that clicking the device name disconnects which is different to what's needed to connect.
One of the advantages the Nexus has over the Mini is the 16:10 screen great for widescreen movies. It's no surprise then that loss of USB mount (a feature available when many of us decided to buy the Nexus) has hit us hard. Yes there is a paid App which might allow movie streaming but I use the USB to extend storage for the huge game files we must download and so this is a major loss.

Screen brightness is an isolated issue I suspect not caused directly by Android, as most people don't see it.
Everything runs just as fast as 4.1.
Quick Office has a coding problem, not Android.
Stop.
I have only seen 1 real bug in 4.2 and that's the missing December bug.

It is most certainly NOT as fast for me, just because it is ok on your device please don't assume everyone else's is the same!
I actually love 4.2. A little lag here and there, but I owned a Huawei Ascend with like a 500 mHz processor, a Samsung Sidekick 4G with a 1 gHz processor, and a Kindle fire. Seriously Google isn't perfect (but they are damn close) they released an update you don't like, does that mean you should cry and hit the new thread button? No, it means you should just flash 4.1.2 and save server space. Especially when there are 100 other topics exactly as useless as yours. We don't need more of them.

Has nothing to do with Prism, the heuristics on the backlight seems to allow it to ramp up and down faster than it did before. In fact before the N7 seemed to be very stubborn to change levels, now it's a little too fast perhaps.
No matter what version or ROM I'm using I don't use automatic brightness. I use the lowest setting and adjust when I need to.

Hating it and loving it ? - wow these are strong words for an OS. Just like W8 people just can't work out whether its the cool thing to be for it or against it yet even though there's no need to take sides or feel possessive about it - we're all here just users equally dependant upon the working of Google aren't we?
One sure thing though - bugs will iron out but things like the way Bluetooth works now and the loss of USB mount are major hits for those of use dependant on those features for the last 4 months.
USB mounting was never part of 4.1... why are people suggesting it was? You needed root and stickmount or a custom ROM.
Stickmount will update eventually. Stop blaming Google for breaking something they never supported in the first place.

Hey everyone,
So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast. :good:
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.
Caveats
There is a (theoretical) security risk, in that seeding /dev/random with /dev/urandom decreases the quality of the random data. In practice, the odds of this being cryptographically exploited are far lower than the odds of someone attacking the OS itself (a much simpler challenge).
This may adversely affect battery life, since it wakes every second. It does not hold a wakelock, so it shouldn't have a big impact, but let me know if you think it's causing problems. I can add a blocking read to the code so that it only executes while the screen is on. On the other hand, many of us attribute lag to lacking CPU power. Since this hack eliminates almost all lag, there is less of a need to overclock, potentially reducing battery consumption.
If you try it, let me know how it goes.
ROM builders - feel free to integrate this into your ROMs (either the .apk / application, or just the rngd binary called from init.d)!
If anyone's interested, I've launched a paid app on the Play store for non-xda users. As I add features I'll post the new versions here as a thanks to you guys (and xda community at large for being such a great resource). But if anyone's interested in the market's auto-update feature, just thought I'd mention it.
Cheers! :highfive:

Just wanted to share this with anyone who hasn't found it through the portal or general thread popularity yet, the original thread can be found here.
As you can see, this .apk (it's easiest to download it from the original thread which has a QR code) claims to increase speed and fluidity in any ROM on any device. Having installed the .apk and set it up correctly, I don't see any significant difference whatsoever. The phone feels marginally faster but I'm almost certain this is just a placebo in my case. HOWEVER, I am very clearly in the minority here as there have been 499 posts in that thread almost all of which are praising the OP, so you should definitely try this out. There are no downsides to it and it doesn't even involve flashing. Just download and install an .apk and turn the thing on and all should work.
Please post any results with as much information as possible here too, it may be down to NexusHD2 JB

I am a researcher of bad deeds by corprocratic elites that run our world and if you didn't see this coming five years ago when folks like myself were shouting from the tree tops about these globalist controlled tracking devices then idk what to tell ya. If you are on the internet you have a link established with someone who is watching every move and unless you use an anonymous encrypted VPN to conceal everything you do and do not use social networking or any major search engine except startpage.com then the matrix already has you. And if you believe it is only the few companies named think again. A recent piece of legislation passed by the house and senate allows companies like telcos to get paid govt subsidies to forward information to these alphabet agencies AND more significantly removes any abilities you had to pursue a litigation based remedy against the companies doing this. And since it wasn't the govt spying on you directly, they now have an out for illegally collecting information on citizens. PS this was going on looooooong before the PATRIOT ACT was passed and this is the norm and not the exception. When SHTF economically here all too soon they will know who you are and who you may turn to for help. They will have completed their psychological profiling and prediction algorithms based on your past behavior and will know what you will do and when you will do it with stunning accuracy..
And if you scoff about this, you haven't done your research. Anybody remember that [open]BSD has those backdoors paid for by tax dollars? You think BSD is alone?

Most roms available are based on android, and only a few demo operating systems have been created that are not based on android for the Nook Color.
The Ubuntu Touch demo works for the most part.
Someone got open WebOS working on the Nook Color, but it might take a while to get it working on your part.
You could always port over your own OS if you are that desperate.
If you really want a kinda non google rom and that works well I would have to suggest the original rom that came with the Nook. Even though it is still running android it was modified by Barnes and Noble and is different than the android interface.

I work on a project designed to compromise the data collection. Look up OpenPdroid and the auto-patcher. All system and app calls for data will still go through, but you will be able to either block or spoof the data returned.

From the posts I think many are not realizing that the spy features are BUILT IN TO THE CORE apps and frameworks of the OS especially where proprietary gapps are included. You could disable certain features but then it also wouldn't function properly for your own purposes. And if it is based on android it probably is riddled with the same issues.

Dump Google Apps / Get OpenPDroid ... Use ixquick Search Engine
I'm running CM 10.1 but I don't install Google Apps which makes a huge difference! GApps is the most invasive, nosiest app I have ever seen! Without that on your tablet you do not have to register the device or provide any info at all... no "setup"... Then I use pandaapps.com and other alternative app sites/ways to get apps. Right after flashing a ROM I also disable all location/GPS crap and go into the browser settings and do the same before enabling wifi. Then I make ixquick.com the search engine. On top of that I am working on installing OpenPDroid but it's not the easiest thing to do yet... the auto-patcher that works in Windows to compile the ROM and PDroid patches doesn't work with every ROM. But OpenPDroid will allow you to control what info and access apps get, by (for example) setting PDroid to give the app null, fake, or random data in place of real data. It's still not perfect but it's a lot better....

After reading the article, I'm glad I'm not the only one who's experiencing this issue. I've noticed my Nexus 7 slows down and becomes less responsive during heavy writing task(downloading stuff at high speed, stuttering browser, etc).
Before anybody jumping in and saying they don't have the issue, the point is it does happen and it happens to other devices as well. Same issue can be said for Galaxy Nexus, Asus Transformer Infinite Transformer Prime. A good way to test this is to see how your tablet performs when you download something over 1MB/s or 2MB/s.
The reasons some people don't see this are:
1. It's hard to tell in short term. Usually the memory i/o speed degrading starts to show after 6 months to 1 year or longer depending on the quality of the flash memory they use.
2. Interfering factors. Many people think the lag is caused by ROM or kernel. It could be true in some cases.
3. Inconsistent quality control during manufacture. I'd assume that out of some bad batches, there will be also some good units. Also not every device use the exact same flash memory chips.
4. Personal usage difference. Flash memory's life span depends on the limited number of writing/reading. So the degrading rate also depends on each individual. Some people are heavy users who constantly perform copying/reading/removing actions on the device while some others may only use it for internet access which results in less taxing work.
Actually the i/o speed issue is one main reason I'm looking forward to next generation Nexus 7. Just hope ASUS can use better quality flash memory next time.

I don't know, if Asus doesn't get it right on 2 devices, all of which I have owned, I can't imagine that they will get it right on the next 2 devices. I was so tired of my laggy infinity that I just sold it on ebay. I was so tired of my laggy nexus 7 that I did a factory reset. But then again, these were essentially first generation products. Hopefully the second gen will be better (seems to contradict what I just said, haha.) I am probably going to wait for a little while before I get the next nexus, anyway. I have an expensive habit of getting the latest on launch, most of the time regretting my decisions.
I haven't seen any of the lag these sites and users complain about. Maybe its because I was more used to my Iconia A500 dragging its feet at the two year mark but I can't see how this is "laggy" or "unresponsive" at all. I think this is the result of seeing the device as "old" rather than "new" so you notice one thing and look for 100 others you never noticed. In the end though it could be worse. You could've paid a pretty penny for it to turn to crap All I can say is that I have not noticed these problems and that if they remain after a wipe and reversion to an older, version then they must have always been there.
Its flash storage over all devices. I've seen the same lag on my wifes ipad and iphone.

Well, the thing is the performance drop is very distinct and easy to see. When the device comes to a stall during some background writing/reading, then it's problem.

Every computer I have ever used - that's over a 30-year period - could have its' UI brought to it's knees with heavy I/O. It's not a surprise, really: mass storage is typically the slowest bandwidth device (ignoring things like uarts or keyboards) in the system.
The problem can be pushed into a corner - for instance using massively more RAM than is needed by the memory footprint of the kernel and apps, so that there is plenty of fast file cache available, but even in that case, a source of sustained high-speed I/O will eventually exhaust the write cache, and slow writes will start occurring and queuing up against all other I/O activity.
But that kind of thing doesn't happen in a $200 tablet. RAM ain't cheap, nor does it come for free in terms of power consumption (and thus battery size needed for a given "on battery" time).
On top of that, you have all the problems of write amplification that occurs with flash memory that performs block erasures and wear-leveling.
IMO, if you think this is something that only occurs on certain OS releases, or certain hardware, you are probably going to be disappointed with every device you ever buy. That will be the case until a non-volatile storage media exists with sustained read/write bandwidth that exceeds that of the system memory bus, and also is not affected by the number of independent transactions per GB of I/O.
BTW, the fact that someone on the internet complains about a problem with symptoms similar to those you experience does not imply that the same root cause is involved, nor does it say anything about the frequency of occurrence of those symptoms amongst the general population. I suppose that some small percentage of the world's population is tired all the time; but that doesn't mean they all have Lyme disease, nor that everybody has it.

Gruber linked to it. Joy. Prepare for this article to be linked to by every iOS fanboy from now until the end of time.
My theory is that its mostly prevalent on the 8 GB models that were only sold for a short period of time, and thats why only a few people, mostly early adopters, have seen this.
I torrent ... "things" ... at over 1.5 MB/sec.
Don't see a dip in speed at all. Try changing your IO schedulers, people.
Mine gets slow when I have less than 3gb of storage open.. Above that, it is fast. It's not a permanent problem. Try freeing up space before damning the Nexus 7.

The N4 has twice as much RAM as the N7. See my comment about file write caching above. It is quite reasonable to expect the N4 to perform better under equivalent load as there will be substantially larger free memory for write caching (everything else being equal). Simply put the N7 will hit the I/O queue wait wall first.
A statement from one or two users that "my tablet doesn't do that, what are you talking about" is just as relevant information as one or two users claiming "my tablet is always slow".
Neither report is a denial of the experiences of others; but both taken together are a demonstration that the trouble described is not universally experienced.

Simply put the N7 will hit the I/O queue wait wall first.
A statement from one or two users that "my tablet doesn't do that, what are you talking about" is just as relevant information as one or two users claiming "my tablet is always slow".
Neither report is a denial of the experiences of others; but both taken together are a demonstration that the trouble described is not universally experienced.

I'd also be surprised if most Nexus 4s have had the same amount of wear on them as the Nexus 7s. Just saying.
Your I/O scheduler definitely helps, but unfortunately software fixes can only play catch-up for so long. It's one of the things I really do dislike about flash memory-- yes, I know that spinning disk media also has wear, but I've had some drives running for...practically forever, really. I just don't feel comfortable knowing that SSDs and flash will eventually cop out because of how they're designed (but a lot of that, I'll plainly admit is a psychological thing and has little to do with the tech's actual reliability).

Your right when I wake my n7 from sleep with no apps updating or anything running, and it moves at a ants pace. I am wrong its me I guess...right. Every user should have to unlock root and flash a kernel to change how it runs.
I read the comment you made before, its the same copy pasta stuff from when the nexus 7 didn't have issues having the storage full, back early on. This what makes xda so great, people have a issue and someone chimes in tells them they are wrong, or ten posts of "420 root it, and flash mer devs kernel"
But your right my tablet should mostly be lagging because running the launcher and maybe an app slows everything down because its designed to run an app and that's it.

EDIT: bftb0 summed up what I wanted to say far better

Nobody has denied anybody's experience. If you say that stuff happens, I believe you.

off topic = irrelevant. But nice segue.

If that happens on a stock device with no apps that's been rebooted within the past few days, and there are no other pathologies involved (e.g. nearly-full or corrupted file systems), then *probably* there is a hardware problem involved.
Look, I get it. Plenty of folks just want to use their device, not worry about details, and have it work as if it were mint. And they want it to behave that way even after customization (adding random apps). But practical experience with a wide variety of computing devices reveals that performance problems always hinge on details - sometimes incredibly tiny and obscure details. Those "details" can be any number of things - "soft" (correctable) hardware defects, bugs in the OS software, user software that is installed, all sorts of stuff. And even for technically sophisticated users isolating the root cause can be difficult. Until some detective work has occurred, there is no justification to place the blame on any specific component.
BTW, I know how frustrating it can be. My old Android phone (rooted, OC'ed & CM 7 ROM) currently can not be operated with both the messaging app and launcher app locked in memory (It only has 190 MB of RAM!). So I get to choose between losing text messages or waiting 15 seconds !!! for the launcher app to repaint the first home screen after leaving a resource-hungry foreground app such as Maps or the Browser. If I try and set up the Android LMK to do aggressive memory reclaim, the device will occasionally enter a "thrash of death" where the LMK is killing off threads as fast as they are generated - and the whole device will go frozen for minutes at a time. So, yeah, I get the frustration.
That of course is indeed "my fault". I could go back to a factory stock ROM (Eclair w/ HTC Sense - ugh). But I don't want to. I want certain features, and I want certain apps, too. You might claim that's not comparable to a user having a stock ROM device with a whole bunch of market apps installed; but until those apps can be cleared of suspicion, blame cannot conclusively be laid anywhere.
It is what it is. Computers that do not exhibit load dependent performance problems do not exist. That doesn't make things anybody's "fault" - but it is highly unlikely that Google (or Apple, whomever) is going to send someone over to your house to figure out what goes on with your tablet.
So, moaning about a problem on the internet might make someone feel better for a few minutes, but at the end of those few minutes, the problem(s) will still be there.
And BTW I completely get it that if I were to be having a performance issue on my tablet, and I wanted to clear my 72 market apps from suspicion, it would take me as many as log2(72) ~= 7 binary bisection trials (remove half of apps each trial) to finger a suspect or clear them all from suspicion). Pain in the rear to be sure; but it wouldn't be any less work on a different device - Apple, Asus, HTC, Moto, Samsung, whatever. And if it were an intermittent problem? It might take a huge effort to isolate the cause. Way longer amounts of time than simply ignoring a second or two of hesitation in the UI.
But the OP created this thread in the General section, not the Help / Q & A section; was he even interested in getting help?

I too feel this way since 4.2 update. I'm stock unrooted with 7gb free of storage.

Try rooting your device, install lagfix.
From the comments in the article linked by Op, should help.
I did not try myself since I'm not having these issues.

Werd. Lagfix made my 7 feel like new again. I scheduled it to run once a week and haven't had any problems since then.

Lagfix does fasttrim command but many kernals nowadays do that already so the effect could be placebo unless you are on the kernel that doesn't fasttrim well.
