NASA's James Webb Space Telescope Primary Mirror Fully Assembled

Using a robotic arm reminiscent of a claw machine, the team meticulously installed all of Webb's primary mirror segments onto the telescope structure. Each of the hexagonal-shaped mirror segments measures just over 4.2 feet (1.3 meters) across -- about the size of a coffee table -- and weighs approximately 88 pounds (40 kilograms). Once in space and fully deployed, the 18 primary mirror segments will work together as one large 21.3-foot diameter (6.5-meter) mirror.

"Completing the assembly of the primary mirror is a very significant milestone and the culmination of over a decade of design, manufacturing, testing and now assembly of the primary mirror system," said Lee Feinberg, optical telescope element manager at Goddard. "There is a huge team across the country who contributed to this achievement."

While the primary mirror installation may be finished on the tennis court-sized infrared observatory, there still is much work to be done.

The 18th and final primary mirror segment is installed on what will be the biggest and most powerful space telescope ever launched. The final mirror installation Wednesday at NASA’s Goddard Space Flight Center in Greenbelt, Maryland marks an important milestone in the assembly of the agency’s James Webb Space Telescope.

Seems like every time I find a great news and article discovery system it eventually goes away. You guys created what I consider the best one out there at the time. The spiritual successor to Findory / +Greg Linden which will always be dear to my dear to my heart. Really sorry to see you go.

Why such a short sentence? This is a law enforcement official that stole in an investigation. This sort of thing should be met with the harshest sentence possible. Our justice system is insane and corrupt.

Out of curiosity, when you use fi do you know which network (t-mobile, sprint) is being used or is there a way to find out?

I thought I'd give an update to this thread, eventually the phone said that it needed to complete the setup of my account and after that step it now does connect to both networks. I also discovered that signal check does a good job of telling you what network you're on but I prefer phono since it puts a little icon on the notification bar representing the network you're on. It's much easier to just figure it out with a quick glance.

Does anybody know how to get keyboard shortcuts for doing spell checking? Things like next word, previous word, show suggestions, change spell language etc etc.  I am really used to using the spell checker on a Mac  The best spell checker I ever had was http://www.rainmakerinc.com/  but sadly the developer passed away. I would gladly pay big $ to get that level of functionality back.

I have been getting more security conscious lately. I am coming to realize that probably the most secure device I own is my iphone because of the extreme level of sandboxing it does. Hack attempts are becoming so prevalent, who knows if I have a keylogger on my mac's. I doubt it but seriously if you got your hands on my banking passwords you could do some serious damage especially if you were slow and meticulous in your attack.

One of the reasons I really like the chromebook is because of what I perceive to be their inherent security. Do extensions pretty much remove this security? Does the permission "read and change all your data on the websites you visit" which all extensions seem to need, allow the extension to read what I type in such as passwords? I would think not but... Do all extensions have the same level of access to https sites? 

I think its a matter of time before the general public gets taken for a ride by malicious code that becomes widespread before it gets caught after doing lots of damage.

Any advice?  -Thanks..

+Steven Fernandez if you have a cookie that automatically signs you into Google then the keylogger extension will not be able to grab your password. It works by reading each keypress you make, so when you type in a password box, you're owned!

I don't know if Google scans for this type of malware. There are legitimate uses for the basic techniques the extension uses, and there are probably many ways for an extension to grab your data if you give it sufficient permissions. So an automated scan would be very tricky, and I don't know if Google does manual scans. According to someone who probably should know..."I am sure Google automatically screens any extension uploaded -- but the bad guys will, of course, do their best to trick automatic screening," so he doesn't know either!

The quote is from here: http://www.linuxinsider.com/story/81925.html

Facebook Notifier (https://chrome.google.com/webstore/detail/facebook-notifier/dfjbdahfeiockocfngedbadjgjncidag) seems not to be malware. The main code looks fine but I didn't check the javascript libraries it uses, which could have been modified to hide something malicious.

Chrome actually lets you see the code! If you turn on Developer Mode in the extensions page the ID will be shown (dfjbdahfeiockocfngedbadjgjncidag for this extension). This is the same as you see in the URL for the Web Store and can also be used as a path to the files which make up the extension.
For example, the Manifest file, which describes the extension name and its permissions, is
chrome-extension://dfjbdahfeiockocfngedbadjgjncidag/manifest.json

The bit which gives the scary message when you install it is this line in the Manifest
  "permissions": [ "webRequest", "webRequestBlocking", "tabs", "http:///", "https:///" ]

The extension works by showing a "page action" badge in the address bar whenever you have a new Facebook notification. This type of extension is intended for when an extension adds functionality to a specific website. So if you design an extension to work on youtube.com, your Manifest file would ask permission for that particular site alone and the extension's badge would appear whenever the user went to Youtube.

The Facebook Notifier developer is doing something slightly different - they allow the badge on every site but show or hide it depending on whether you have a notification. The extension code only references facebook.com and google-analytics.com, but it needs permissions on every site in order to show the badge there.

What they could have done was to have a button in the toolbar, visible all the time, and change the button (or have an overlay) when there is a new notification. This would mean the permissions could be restricted to give the extension access only to facebook.com and google-analytics.com.

It's fine for now, but the worrying thing is that it has far more permissions than it needs and can be auto-updated to include malicious code. In April last year someone pointed out in the Support section that the extension does not meet the criteria for a "page action" and that requesting access to all websites "is unnecessary and suspicious," but the developer has made no changes since then. I would choose not to install this extension.

The extensions I've written have as few permissions as possible, even when it compromises functionality. For example, my dictionary extension (linked above) opens a definition page in a new tab and has no special privileges. Other dictionary extensions show definitions in a nice popup, which is better for the user, but require the same permissions as the keylogger.

Why run the beta channel?

I have several Chromebooks and most are on the beta channel but is there anywhere I can find a current list of features only available in the beta channel? I'm familiar with http://googlechromereleases.blogspot.com/ but it's not the easiest stuff to read if you just want the highlights.

The beta channel get updated every 1-2 weeks while the Stable channel only once a month (I say only but once a month is pretty Dang good) so its an ever changing list of added/deleted features.

Why on Android when I get to the share menu does it ask me if I always want to share to the same program? I know that some people probably like that but for the majority you don't want to lock yourself in with one program. The fact is once you set that up it's not all that intuitive how you turn it off. It would make more sense to me to just keep that list sorted by most frequently used at the top.

Does anybody know of a similar tool to "ip scanner pro" that would work on a Chromebook? Is this something that can be accomplished o na Chromebook?

https://itunes.apple.com/en/app/ip-scanner-pro/id404167677?mt=12
IP Scanner Pro for Macintosh scans your local area network to determine the identity of all machines and internet devices on the LAN. Powerful results, yet easy and intuitive to use. IP Scanner is all about customizing the way you view your network. You may apply custom names and icons to the devices on your network and adjust the type and amount of information you see in the network overview; don't need to see the MAC address column...don't disp...

I discovered http://apps.evozi.com/apk-downloader/ which is great for downloading any apk but so far no network scanner that through arc welder actually scans whatever ip range I happen to be sitting on. Hopefully a developer will pick up on this and port it to the chromebook. I would gladly pay for this kind of tool and many others.
