MeetMeego.org has the dirt on the details of Nokia's next two MeeGo devices [German]. To sum up: the first device, the (very) long-awaited N9, has a similar design to the N900 - a horizontal sliding 4-line keyboard, but this time with a tiltable screen, a 1GHz ARM Cortex A8-based processor, a 12MP camera with Carl Zeiss lens, and HDMI out. It will be a developer device, distributed at developer conferences such as the MeeGo Conference in San Francisco in a couple of days.

I believe that one of the cores is dedicated to running the baseband.
Technically most dual core phones are triple core. Two application cores (running Android etc) and another arm 9 running baseband (running a real time microkernel).

Sorry to ask this, but exactly is the "baseband" ? Network signal demodulation/decoding and analysis ?

Don't be sorry.
Yes it does that (in a dsp) and holds the telephony stack (GSM etc) . Telephony functions are exposed to the OS as a service and the application (that is the main os) does not (and can not) govern them in order to maintain network access.

"Actually, dual-core phones have existed for years already. For example N96 sports 2xARM9 cores and it was released already back in 2008. So yeah, they're definitely not a new thing and even back then it managed to last the whole day without recharging.

No, N96 did indeed use both cores for applications. After all, why even market it as a dual-core phone if only one was in use? The problem -- as far as I understand it -- was that all applications ran in single-threaded mode, which obviously means that they'd still use only one of the cores at a time. And since both cores were clocked at only 264Mhz -- half of what competing phones did at the time or even less -- it made all the applications really sluggish and slow.
It was a really half-assed attempt at dual-core systems from Nokia and it would have been a bigger hit if they had actually redone their apps to use multi-threading and added support for that in the OS itself. I owned a N96 for a while and moved on to N900 later on, haven't regretted it even once :]

"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.

"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 »
