XMPP (eXtensible Messaging and Presence Protocol)

I am studying android. The android framework provides lots of useful services for the applications. One of them is XMPP service. This is for a kind of open source IM. It can be summarized like this.

XMPP is for a technology for streaming XML over a network.

It is standardized by IETF. RFC 3920 for XMPP core and RFC3921 for XMPP IM.
XMPP was called jabber at the beginning because it had been developed in that name as a open source project. After standardized, the name changed to more formal XMPP. Still some people call it jabber.

Please look at here for more detail.

Native Client

Google announced it's new project at the very early stage.
Native Client is an open-source research technology for running x86 native code in web applications. They feel that the current web-based applications have lots of limitation to be a replacement of the desktop versions.
Instead of creating a new OS, they seems to decide to use web browsers as an OS.
It is perfectly Googlistic.
I think it is noteworthy. I will see how it evolves.

Please look at here for more detail

Nokia's new Touch UI?


It has been surfaced out of blue.
Some people (including me) may have been disappointed with Nokia S60 Touch UI shown with XpressMusic device.

Nokia is preparing something big behind scenes. Look at the screenshot above.
Please look at here for more detail.

FireFox 3.1 Beta 2 arrived


Mozilla release a second beta of FireFox 3.1 (my favorite browser).
My favorite update is TraceMonkey. It gives firefox a fast speed that is on a par with Google Chrome. Actually Chrome is very slow in my PC for some reason. I did not figure it out. So I set back to FireFox 3.1 Beta 1. But I always have missed the speed of Chrome.
Now, it is FireFox's turn to speed up with the same technology that is behind the speed of Chrome.

I love Firefox.

Here is some updates list.

  • Added a new Private Browsing Mode.
  • Added functions to make it easy to clear recent history by time as well as remove all traces of a website.
  • New support for web worker threads.
  • The new TraceMonkey JavaScript engine is on by default for web content.
  • Improvements to the Gecko layout engine, including speculative parsing for faster content rendering.
  • Removed the new tab-switching behavior based on feedback from user
  • support for new web technologies such as the <video> and <audio> elements, the W3C Geolocation API, JavaScript query selectors, CSS 2.1 and 3 properties, SVG transforms and offline applications.

3. Don’t neglect your customers’ most important need: a better price.
4. Make it easy for partners to customize your product.
5. Business isn’t a sprint; it’s a marathon. Be persistent.

I like 1, 2, 5 personally.

SUN takes a serious step to survive

Even though I though SUN would not an exception to this harsh economic downturn, I could not believe this. Their stock plunged down under 90% of the price of last year.
http://news.cnet.com/8301-1001_3-10097208-92.html?tag=newsLeadStoriesArea.0
Some analysist suggest that there might be a buyout by HP, IBM or DELL as the price of SUN is really low compared to it's real value.

Video Telephony on Windows Mobile

I am interested in Video Telephony on Windows Mobile.
Actually I am not an expert in this field.
As a part lead, I would like to get a general idea about VT.
So I decided to collect material on the internet.
Here are the links I found on that journey.
I focused on CSVT (Circuit Switch based Video Telephony) that is a standard for 3G networks.
Europe, Japan and Korea support this.

LG KC910, successor of Viewty


LG is really doing well recently. They are showing another their good product. 
It seems a really high-end device.  8-MPixel Camera, AGPS, WQVGA (3 inch).
This will be available in October.

See the source here

Sony Ericsson announces SDK for Xperia Panel


Sony Ericsson XPeria is not just another Windows Mobile Device. They are trying to do something like OpenOS. Windows Mobile is also one of OpenOS platforms. But Sony Ericsson seems to like to go beyond that. They releasees SDK for Panel interface.

Even though the hardware is developed by HTC, the software is in control of Sony Ericsson itself. A glimpse of that showcase gives me a good feeling.

Google Chrome (Google's own browser - open source)

The rumor has been around for a long time that google is developing their own browsers for their web applications. Now it surfaced again with clearer indication. (Now it is official)
The name is revealed as Chrome and the comic is up on the surface to show their design concept and how it will work.

Update: Now it is official. Google will announced it and hosted a conference to talk about Chrome.

Update2: I tried it. It seems faster but sometimes slow. Because it is using lots of processes, the situation where lots of process are already running slow the performance. Anyway, a few features are really my tastes. Secret mode, Detachable tab, Own task manager, and source inspector.

AppStore, Android Market, SkyMarket


Application store war begins.
Apple is leading the market with AppStore.
Android follows the trend with Android Market which is very similar to AppStore.
Finally Microsoft is trying to catch up with SkyMaket (I am not sure if this is a final name).

Now we will see what Nokia brings about Application Store. Will they provide it via Ovi?

HTC S740 (Diamond Variant)

HTC is really good at using a source to make lots of line ups.
They are adding a keypad and a qwery keypad.
It is a little long and thick now. Actually this phone seems to be based on Windows Mobile Smartphone (non touch device)

More screenshots

Palm Treo Pro (850)


Look at the new phone form Palm
They seem to fail to load up their own os in the new phone.
It is still Windows Mobile 6.1 based.
The look inherits from their own successful Palm Centro.

For your information, actually this device is made by HTC.
It is based on MSM7201. It includes Wi-Fi, GPS, Bluetooth.

HTC Dream (Android) soon to be available ?


HTC Dream has been around for a while. It was expected to be out in 3Q of this year. Actually there was a rumor it would be delayed though Google and HTC denied it.
Anyway now we can see a few glimpse of that rumored phone.

I am not sure how much impact will it bring to the market.
As someone said, now all depends on the software.
We will see later.

It's been a while. Start again.

I have been away from blogging.

But it turned out a huge burden to me.
I will try it again now.
This time I start from a small things.

This is my new ways to post articles.
1. List up all the hot or interesting issues
2. Try to comment briefly on those things (usually in a line)
3. Supply the links around the topic

HTC Diamond (is it real iPhone contender?)


While iPhone3G news is booming up, there are another tubulent event going.
HTC announced their flagship model of this year, Diamond.
It is Windows Mobile 6.1 Professional based SmartPhone. But it does not look like a just another Windows Mobile Phone. It looks to have its own UI and style.

Look at the following link,
http://www.engadgetmobile.com/2008/05/06/htc-touch-diamond-hands-on/
It looks really cool. I would like to get my hands on it.
It is sleek and sexy. I like the back design of the device.
Diamond is not just a look. The features are great.
3.2 M Camera, HSDPA, WiFi, YouTube, GPS... wow, it has all in its 11mm thick.

3G iPhone (2nd Generation)

Lots of news and rumors are telling 2nd Generation iPhone is imminent.
A few interesting features
1. GPS chip
2. Shiny black plastic back panel for improving the phone's antenna.
3. Immersion's haptic feedback
According to China-based Commercial Times, Foxconn is ramping up to ship 3 million 3G iPhone during the month of June.

This news is not good for competitors.
Sorry, Samsung (Instinct), Nokia (Tube), BlackBerry. You need more speed to catch up iPhone

Starting again

I has been away from my blog for a while. I was busy and lasy. I took over the responsibility of leading a small part (about 15 people). It was not easy task. These days, I feed a little bit old. I would like to go back to my fever days.

Here goes today's hot topic.
- Sanyo may selloff to Panasonic
. Around the globe, the mobile phone players are having difficulities. Lots of emerging companies (specially from Taiwan, China) are comming. The competing is getting fiercer. They always have to try a new one. If they fail to catch up the latest technology, design and trends, they just fade. Motorola is an example. Sanyo looks like no exception.

3G iPhone rumor
- It is a little bit old news. Rumor mills are running for 3G iPhone. I will see if I can get 3G iPhone in this summer.

MID (Mobile Internet Device)
- This is a new trend. Look at the HTC Shift. Actually I had been in this kind of market a few year ago. At that time it was not mobile. It was a Web Screen Phone. We thought Web Pad as a next generation. But the timing was bad. We failed to get the attention of large audience. Now this trend is coming back.

Dell mobile phone with Google, Garmin mobile phone

Dell mobile phone with Google
- Last year, there had been lots of rumor about Dell's mightbe new strategy in consumer market. They hired Motorola vice president and bought ZING systems for music. Some people had an inkling that they would reveal smartphone in this year (2008). Now, the rumor mill is running again. MarketingWeek say about the Googld Android phone from Dell. It says it will be revealed at 3GSM in Barcelona in the next Month. From the recent market specially in the US, smartphone seems to be a leading factor.

Garmin mobile phone
- One more surprise. Garmin, one of the best GPS navigator developers, announced their first mobile phone (named nuvifone) in the market. It gets intersting. Some of consumer players, such as Dell, iriver, Garmin, and Apple are joining mobile phone market. This will change the landscape of the mobile market. The troubling issue in the mobile market was the usability. The traditional mobile phone players have been failing to achieve this goal. But this consumer-oriented players are very good at easy user interface. This year would be a milestone for easier mobile phone userability.

Motorola may exit handset biz, Google to rescue WiMAX

Motorola may exit its handset biz
- One of the analyst said about the possiblity the giant mobile handset maker may exit the handset business to save the company. From the last year, we are seeing lots of smoke from Motorola. It had been no.1 in the handset market. It is no.2 that is having really big trouble. Samsung is following very closely. At this year's end, we will see Motorola as no.3 or none. It is getting interesting.

Google to rescue WiMAX
- I had though WiMAX (WiBro in Korea) is in great danger because Sprint is troubled last year. They broke up with Clearwire and did bad in their business. This year seems to be not a good year for launching a new (maybe expensive) service while the world economy is so shaking. It is really surprise that Goolge invested money to WiMAX. Let's see what will happen in the second half of this year.

Etc
- Nokia bought TrollTech
- Mobile UI by Mozilla [1,2]
- Skyfire full browser on Windows Mobile
- AT&T will launch MediaFLO next week
- Sky Dayton step down
- Kyocera is pulling out of china

Rumor: Apple includes WiMAX in the notebook

Rumor: Apple might include WiMAX in their notebook products, especially for ultra portable one.
- Apple might introduce new notebook lineups in this time Macworld. And it can contain WiMAX in it. I am sure of that. Apple always surpised us and can do the same thing again. A few hours later we will know what Steve has for the surprise.

Amazon MP3: no-DRM, iriver w10 gsm, A-VBS, SlingPlayer on iPhone

Amazon MP3 : completely ready for the war againt DRM protected MP3
- The last of the big 4 majors joined Amazon MP3. Amazon provides no-DRM MP3 music contents to the customer. DRM is the issue debated for a very, very long time. I hope we can see much more DRM-free musics.

iriver w10 GSM : another just iphone-like phone
- iriver has been known as one of the most creative company in the digital world. w10 is a shame on them. I hope they can do better than this. I would like to believe them.

A-VBS and MPG : another broadcast format
- Samsung developed A-VBS and LG developed MPG are another formats for mobile broadcasting. These are out of reach of carriers. These can be deployed independently. It could be good for the broadcasting companies who would not need to pay money to the carrier. But, too many options sometimes are not good.

SlingPlayer on iPhone
- iPhone always could be a hype and a good platform that show your product shiny. When a company shows that something is working on iPhone, it appears to them that they are one of the top most important company. iPhone lacks very important thing. Even though it has wi-fi, it does not have 3G capability. From my personal experience, iPhone platform looks to be unstable. Youtube crashes, Safari crashes. I hope these cons are addressed on the 3G iPhone.

The 5 phases of a Hype Cycle (from gartner group)


What are the 5 phases of a Hype Cycle?


1. "Technology Trigger"
The first phase of a Hype Cycle is the "technology trigger" or breakthrough, product launch or other event that generates significant press and interest.

2. "Peak of Inflated Expectations"
In the next phase, a frenzy of publicity typically generates over-enthusiasm and unrealistic expectations. There may be some successful applications of a technology, but there are typically more failures.

3. "Trough of Disillusionment"
Technologies enter the "trough of disillusionment" because they fail to meet expectations and quickly become unfashionable. Consequently, the press usually abandons the topic and the technology.

4. "Slope of Enlightenment"
Although the press may have stopped covering the technology, some businesses continue through the "slope of enlightenment" and experiment to understand the benefits and practical application of the technology.

5. "Plateau of Productivity"
A technology reaches the "plateau of productivity" as the benefits of it become widely demonstrated and accepted. The technology becomes increasingly stable and evolves in second and third generations. The final height of the plateau varies according to whether the technology is broadly applicable or benefits only a niche market.

2008 Predictions: Open, Smartphone, Mobile Advertising, WiMax

Open
- Open will be a key in 2008. Last year we have seen lots of open access strategy from carriers and manufacturers. I hope carrier loose the their too much tight grip on the control.
700MHz auction (whoever will win, it goes open access),
Google Android (open mobile platform),
iPhone SDK (now real smartphone),
Verizon's open access strategy,
AT&T already open (according to their announcement)

Smartphone
- 2008 will be the year of smartphone. 2007 is the year of the beginning of smartphone market. Actually smartphone has been started much earlier. But it did not take off. With successful iPhone launch and Google android, mobile business succeeded to draw the attentions. We can see huge amount of smartphone device in 2008. Touch screen or not is important. Everybody will want a smartphone instead just rudimentary mobile handset.
Apple iPhone in 3G
Google Android
Blackberry new device like iPhone
Samsung BlackJack3 (?)
LG touch screen phone (PRADA phone, KS20)
Dell's entering to smartphone market
HP
HTC
Lots of taiwanese windows mobile companies (ASUS, GIGABYTE, ...)

Mobile Advertising
- As the screen size is getting bigger and the processor power is getting better, there is a good oppotunity for mobile advertising. There have been many experiments about mobile advertising. In the next year we can see some fruits. Google and Microsoft are also battling in this field. Yahoo, too. Let's see who will win.
Microsoft
Google
Yahoo

WiMax
- This is the year Sprint promised to provide the WiMax to all around the US. Actually I am not sure if this will be a success or not. I am suspicious about the WiMax. Even though they look to create a big market, I think it would be a small niche market. There are lots of alternatives. HSDPA, EV-DO, and 4G.
Sprint
ClearWire
Samsung
Intel

Broadcom won over Qualcomm, Amazon DRM-free Music

Broadcom won over Qualcomm
- Qualcomm chips that infringe 3 patents of Broadcomm are immediately barred from the U.S. market except EV-DO chips with sunset period. Qualcomm always are talking about the workaround. But it has a big flaw. The manufactures who are using those infringing chips already completed the development and is on the way of shipping. Usually the workaound is switching the flawed(?) chip to the new one that workaround the patents. As this is h/w change, the carrier could want to evaluate the device thoroughly. This is not good. I think Qualcomm find the another way to solve the patent problems. There are lots of patent issues with Nokia, Broadcom. If this kind of unreliability conitinues, many of their customers turned away. Worse, the small companies who do not have much resource will lose lots of money.

Amazon DRM-free Music
- Amazon is trying to compete with iTunes. Even more, they are chaning the digital music market. Lots of customers have complained about the irritaing DRM protection. Even though they paid money, they cannot use the bought music freely. I wish Amazon succeed and change the music market.
