As geeks, we're well aware of the importance of running as a normal user instead of as root (UNIX/Linux/BSD) or administrator (Windows). However, while this should be common knowledge to anyone reading OSNews, it's often hard to illustrate just how important it is - until now, that is. A report by BeyondTrust looked at how many security bulletins issused by Microsoft are mitigated by simply... Not running as administrator.

"So in summary... Google has pulled the plug on support on a protocol they've helped popularize, after years of promising interoperability, for reasons that are dubious at best, and in a way that leaves people who don't jump to the new Hangouts app unable to talk to their contacts without any feedback that their IMs aren't getting through... And they've done that with no warning to anyone. I imagine there's a bunch of people out there wondering where some of their buddies have gone, or why their messages aren't getting responses, because this isn't documented anywhere." Google really messed this up. Such a dick move.

The Tizen Greek Community has some screenshots of a very recent build of Tizen running on a Samsung GT-i8800. It looks wholly unremarkable.

Joint statement to The Next Web from Microsoft and Google: "Microsoft and YouTube are working together to update the new YouTube for Windows Phone app to enable compliance with YouTube's API terms of service, including enabling ads, in the coming weeks. Microsoft will replace the existing YouTube app in Windows Phone Store with the previous version during this time." Good to know these children stopped acting like little pricks. Can we have full Google support in Windows 8 now, please?

Yahoo is acquiring Tumblr, the microblogging and social networking website, for $1.1 billion USD. Tumblr offers little revenue but lots of eyeballs if Yahoo can monetarize them. Now Yahoo is bidding for Hulu, the streaming video service. After years of ineffective responses while Google, Facebook, and others took large chunks of the online advertising market, Yahoo is fighting back. Can Yahoo reignite the momentum it had at the turn of the century? What do you think?

"Sources have described iOS 7 as 'black, white, and flat all over'. This refers to the dropping of heavy textures and the addition of several new black and white user interface elements." I couldn't be happier.

"Ilja van Sprundel, a security researcher with IOActive, has discovered a large number of issues in the way various X client libraries handle the responses they receive from servers, and has worked with X.Org's security team to analyze, confirm, and fix these issues."

"Google is facing a new antitrust probe by the U.S. Federal Trade Commission into whether the company is using its leadership in the online display-advertising market to illegally curb competition, people familiar with the matter said." Sucks to be Google today, apparently.

"In the midst of the major press blitz surrounding its annual I/O Conference, Google dropped some unfortunate news about its instant messaging plans. In several places around the web, the company is replacing the existing 'Talk' platform with a new one called 'Hangouts' that sharply diminishes support for the open messaging protocol known as XMPP (or sometimes informally Jabber), and also removes the option to disable the archiving of all chat communications. These changes represent a switch from open protocols to proprietary ones, and a clear step backward for many users." That's why I always say: only suckers trust companies.

"The wave of departures is a sign of internal struggle, but amidst all the bad news, there is a glimmer of hope. According to an anonymous HTC executive cited by WSJ, the crucial HTC One is selling 'pretty good so far'. The executive revealed that HTC sold about five million One units since launch, a performance that is deemed encouraging. However, sales have been limited by the persisting supply issues that still plague the production of the HTC One." Finally some good news for HTC. Five million units amidst supply constraints is very impressive.

"Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). Unlike last generation, you don't need to be some sort of Jedi to extract the PS4's potential here. The Xbox One and PS4 architectures are quite similar, Sony just has more hardware under the hood. Weâll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that itâs usually the lowest common denominator that determines the bulk of the experience across all platforms. On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques." AnandTech does its usual in-depth thing.More News »

Users must be part of the 'wheel' group AND be added to /etc/sudousers in order to have access to sudo. Additionally, to use sudo you have to enter your own password. It's not specifically allowed. Once you use it successfully it will let you continue issuing additional commands via more calls to sudo without a password but only for a given amount of time between calls.
'su' doesn't require any group - just that you know the password for that user, root or otherwise.
Not quite.
On Linux/Unix there is typically only one administrator user - root. Rarely do you ever add another user to the 'root' group. Instead, you give people the privilege to switch user to the root user using su or sudo. See above.
On Windows you actually add users to the Administrators group. To properly do it the UNIX/Linux way you would not do that, but use the 'runas' command instead. It can be successfully done - I've done it before - but it is a major PITA as Windows is not designed to work that way.
Under UNIX/Linux, this is how all software is designed to run.
However, Microsoft has historically contributed to pushing for users to need Admin rights in order to use their daily software. Until Office 2002/2003, Office required Admin rights to run. Only recently (VS2005/2008/2010?, not sure which) did Visual Studios drop the requirement for developers to need admin rights in order to debug software.
It's not that administrators did not want to force people to not have admin rights to use their computer. It's that the software available for Windows - even software from Microsoft - required it!
It's only a problem so long as software is designed to require admin rights to function.
Vista and Win7 are making a big show of it. You don't see so many issues now with it because either the vendors got smart and updated their software to not need it (which has happened), or (where that was not possible, or available yet to the user) people turned it off; and with Win7 the default level was toned down.
