It seems the wifi router comes with AT&T u-verse does not work with Apple TV. Apple TV could not find the wifi network from the build in u-verse wifi router. I found one workaround, that is to turn off the build in Wifi, use an old wifi router (D-Link DI-524) for Wifi instead. But there is still problem with the mirroring from iPad to Apple TV. Since I still have my previous LinkSys wrt54g router, I set it up as second router behind the DI-524, and connecting both the Apple TV and iPad to wrt54g. That worked. Another side benefits is wrt54g is a newer/more powerful router, and could broadcast wider range. So in a summary the architecture from internet to apple TV is something like below.
You may wonder why I add this extra D-Link DI-524 old router. The problem was I could not easily connect LinkSys wrt54g (the newer router) to u-verse modem. So I used the old router as a bridge. If someone has idea to make it work without this extra router, please let me know. (Email: minjie DOT xu AT gmail DOT com; or twitter @stlplace)
There is another problem with setup AT&T u-verse which is not related to Apple TV. The problem is when creating new account at their web site, they prompt for secret question/answer, it appears they don’t take any space in the answer. It was a programming error (web page text field validation) in my opinion, since I have done some web programming lately. The workaround is not to type any space. Simple enough.
This is also after using cable internet for about 8 or 9 years, I am switching to AT&T. I was using their DSL before switching to cable. The main reason is their service is cheaper, another factor is the cable had some connection issues lately.
(Update 05-07-2015) Came across this post regarding how to make direct connection from linksys wrt54gl to uverse router. I tried it but was not successful. It does not like the new local ip address 10.0.0.1 for linksys. But the theory there (conflicting local ip address between uverse and wrt54gl) seems holds, as I saw people discuss similar problem on linksys support forum.
One big complaints on the new iPad is its lack of multitasking support. From technical perspective, I think that’s because iPad will be use iPhone OS, currently at 3.2 beta, and it does not support multitasking. It does support iPod (listening to music) and another task such as browsing web though. Some developers speculate Apple will support multitask in its iPhone OS 4.0.
Oh well, my point here is not just about iPhone/iPad multitasking. My point is trying to discuss whether multitasking, work both for us human beings and for the computers (ultimately controlled by us and supposed to help us work more efficiently). To be honest I don’t have the answer. But I read one interesting article when I google “multitasking makes you stupid”. I did not intensionally typed in those words, it just stands out when I typed “multitasking” in my browser google toolbar (another one is multitasking myth). Anyway, here are an interesting article from the Atlantic (2007)
My logitech V200 mouse is more than 3 years old. Recently it acts a bit strange, basically the clicking does not work very well: for instance, when I intended clicking once, it will click twice, vice versa. So I was looking for a replacement for some time. I found the VX Nano is a good one.
nVidia got no love from the street these days. After yesterday’s earning (earning call here), the stock dropped more than 10% today amid weak (margin) forecast. This exemplifies that the market tends to be short sighted.
From Reuters, Hard disk pioneers won Physics nobel: France’s Albert Fert and Germany’s Peter Gruenberg won the 2007 Nobel Prize for physics on Tuesday for a breakthrough in nanotechnology that lets huge amounts of data be squeezed into ever-smaller spaces.
My take: Hard disk has changed the way we live and work, as we can find it in MP3 players or computers. But hard disk makers are not good investments in general. One can look at Seagate (STX), Western Digital (WDC) long term chart (5, 10 years) to see its so so performance. I think this industry is just too competititive and chronic price cuts makes the profit too thin.
Good technology does not necessarily translate into (very) profitable business. I think Google is a rare specie in the tech arena, with its unique business model and almost monopoly postion in the market, and the ever lower cost of hard drives to store its data
1) Howard Schultz, Chairman of Starbucks, talked about competition from McDonald and Dokin Donuts.
Starbucks is not an advertiser. If other companies are going to advertise and promote specialty coffee, Starbucks is going to benefit in the long term,” he said.
2) iPhone price cut and iPod touch launch: Steve Jobs announced Apple will cut 8GB iPhone from $599 to $399, discountine to offer 4GB iPhone, and offer an iPod touch, which is “an iPhone without phone capability”. In other words: iPod touch will have touch screen, music and video capability, WiFi, Internet, etc. You can check out latest iPod lineup from apple.com
I found some interesting articles about AT&T and IBM. They are written by Wu Jun, a research scientist at Google. I like Wu Jun’s writing style (humorous), and his business perspective of the two companies (very good).
Here is the link to AT&T articles; and here is link to IBM series. Both are in Chinese, and there are 6 articles for each company.
