I was hoping for a better CROSH/HTerm (ChromeOS's builtin terminal emulator) but ended up with some weird something else that I don't understand nor want anyway.

Just curious: Have you tried Gate One at all? https://github.com/liftoff/GateOne

I wrote it to solve the problem of, "I need to SSH right now but I don't want to install anything." I've been improving it pretty steadily for about two years now and people seem to like it. I've even got paying customers so it's certainly usable for at least a few people ;)

If you try it and you think it sucks send me a long, detailed ranting email (you can use the feedback form at liftoffsoftware.com if you want). I love em! What's more useful than honest, detailed feedback? I always fix what I can.

i already told that it's possible but "connecting to local terminal from chrome" is not that possible. maybe you can do it over local SSH connection.

Well, if you're using Chrome on Linux you can just run Gate One ( https://github.com/liftoff/GateOne ) on your desktop and connect to https://localhost/ . That'll let you access SSH or whatever terminal program you like. I use it every day! (full disclosure: I wrote Gate One =D )

> (if you don't hack or bridge the chrome)

i already said that. can you serve Gate One as Chrome Extension? No.

>> Oh, I mean I wasn't impressed with the terminal emulator itself. At least when I tried it, it seemed to have problems with some ctrl-sequences (as in, other things would get them instead of whatever I was running in the terminal emulator). This is true, my go-to text mode editor (yes you can laugh) nano has Ctrl-O for write-out and that brings up the ChromeOS open dialog instead. It's most irritating. I might wait…

Heat is absolutely a problem with the current Pixel. My suspicion is that the Pixel can probably cool itself well under loads you would expect in ChromeOS, but if you fall outside of that usage pattern it becomes problematic.

Hahaha! Have you even used Gmail?

Lots of games (Running Fred, I'm looking at you!) will also peg the CPU at 100%, obviously. Then there's the fact that there's a lot of bad code (JavaScript) out there that does things like downloading 50MB worth of email addresses into an Array :)

Browsers are really bad at this; I wonder how many years it's been since the GIF rendering code was touched in most implementations.

Interesting. On my phone pages loaded with animated GIFs are slow as molasses but on my regular ol' Linux (Core i7, Intel graphics) desktop I don't think I've been to a page where I experienced any sort of slowness.

For example, this page: http://imgur.com/a/Htgmq (Animals Staring, SFW)

That'll bring my Samsung Galaxy S4 (a very current quad-core phone) to a crawl but my desktop won't even get the chrome process above 10%. Maybe it's GPU-related? I wonder if Chrome for Android even uses the GPU, hmm...

At least when I tried it, it seemed to have problems with some ctrl-sequences (as in, other things would get them instead of whatever I was running in the terminal emulator). I also was not very impressed with the weird cursor fading thing it does. Right now I'm running Debian Wheezy on my Pixel with a recent kernel that I built myself (the 3.0.whatever…

Interesting, I was thinking about getting one for browsing/webapp use and remote development over ssh. In addition to the screen, I also like that ChromeOS sounds like it handles OS updates much better than anything else - free, seamless, automatic OS updates for life apparently. Better than Windows 8 trying to turn the computer into a giant tablet or OS X creeping further towards being a giant iOS device. Or linux d…

I have a Samsung ARM Chromebook and I use it all the time. Way more than I thought I'd use it. I bought it as a testing platform for Gate One (https://github.com/liftoff/GateOne) but I end up using it most when, "someone on the Internet is wrong." (haha).

So I'll be chilling out in my Lay-Z-Boy with my family watching a kids movie (that we've watched like six times), surfing the web on my phone and lo and behold someone will say something that needs an old fashioned Internet whomping--with references, snide remarks, and lots of puns. The type of thing for which a phone (software) keyboard isn't suited. As in, "I cannot let this person's false statement go unchallenged!"

So I dash to the office ("Honey, where's my super suit?") and I have a choice to make: Un-cable and remove my nicely-mounted (on a cool swiveling arm!) dual-SSD Acer S5 laptop and haul it back to the living room (you know, so I can share the experience with my family =) or I could grab the Chromebook which is conveniently located near the door and has only a single, tiny power connector.

In less than 60 seconds (maybe 30 if I don't grab a drink on the way back!) I will be back in my Lay-Z-Boy, furiously typing away on the Chromebook. Saving the world from the ignorant, shills, and Microsoft fanboys.

Why not spin up an Ubuntu VM in VMware or virtualbox? I'm not knocking the koding terminal, but "I want a Unix environment without dual-booting" is a fairly standard VMware use case.

Spinning up a Virtualbox, especially on a machine with low resources unfortunately is a kill. Besides the Terminal, Koding has features like private Groups, Collaboration, Online editor and so on. That means once you create and begin to use a VM, you can access it from everywhere without any hassle with just one login!

Pretty much took the first few words out of my mouth, there. The fact that this is accessible from any web browser I think is the killer feature. I can't install putty or access ssh on every machine I use.

Basically, this is just plain awesome. Cheers!

I was hoping to try this on my iphone... I made it past registration but the site doesn't seem too mobile (small screen) friendly after that. I wasn't able to read or close the modal that came up.

Those aren't nearly big enough! See instead: http://rainbowdivider.com/, or better yet http://totallytransparent.tumblr.com/ (note that in the latter one only the animated images are GIFs)

But now, a trick, to make browsers even angrier (which is starting to come up as a use-case in, e.g., forum signatures and avatars):

1. set the GIF to a non-native scale (e.g. width="100" height="100");

2. apply a CSS animation to it, where the CSS animation loops a filter() value on the GIF. For example, filter: hue-rotate() the GIF through a 360 degree cycle every 2s. For maximum pain, apply a filter: blur(). (Warning: this last one may actually crash your browser, or at least cause severe artifacting on random parts of the page. I've been intending to report it to Chrome's bug-tracker for a while...)

I believe this causes as much havoc as it does, because GIFs are always decoded on the CPU, and the results of decoding GIF frames and scaling them to display size are never cached; instead, each time a GIF transitions to a new frame, it writes the frame-delta directly on top of the previous frame's video memory. So, when you apply a GPU-bound filter to a CPU-bound write-heavy texture, you give the GPU's pipeline a pessimal case.

I have $1000 here waiting for you if you can break from one container to another. I need valid proof in the form of source code for your exploit. send it to hello @ koding.com and we will paypal you the money.

Is this offer open to anyone or just the person you are replying to?

Anyone ;)

Does anyone know what Koding.com actually does? I watched both videos, read the "NOW PUBLIC" blog post, and I feel like it might be awesome - but I don't know. Is there a page that details what the product actually is? Kinda feel dumb for even asking, but I can't seem to find out?

They are providing an easy way to create a sandbox to code or learn to code. A simple use case would be if you were to teach a class on coding that required a Linux environment to compile C, but the students brought their own laptops, you could A. Struggle with all the possible laptop configurations and how to install VMs and/or the proper packages on those computers or B Use koding.com and have everyone do their pro…

Thanks for the reply. Sounds neat. Sure be nice if Koding had even a single web page the said this. :)
