This is so awesome...
I tried so hard to do this..
But i just don't know about electronics and labview good enough to do what you did.

This is truely awesome.
What's the ADC bit for it?

don't we already have enough garbage in low earth orbit? give me one good reason to shoot this kind of things with no specific purposes

hmm...side winds too strong?.. iwonder how about stronger thrust at last stage to give more reaction time for the lateral thruster
 
SpaceX Falcon 9 Attempts Landing on Barge [Closeup from Barge]
April 16, 2015: The SpaceX Falcon 9 rocket's first stage is seen attempting a landing on the SpaceX barge out in the Atlantic Ocean during the CRS-6 commercial cargo mission to the International Space Station. Landing tests of the Falcon 9 rocket's reusable first stage will continue on the CRS-7 resupply mission to the International Space Station currently targeted for June 2015.

"Feedback control" this is all in some sort of lad's code, surely.

Warp Drive - post for Matt
An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel.

The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" .

Why 'baking powder' increases efficiency of plastic solar cells

' ... Infographic that shows the effect of the co-solvent on the solution of two plastic components (polymer and fullerene molecules) during the production process of the plastic solar cell. Without the co-solvent droplets of fullerene molecules are formed which restrict the efficiency of the solar cell. With the co-solvent the polymer molecules fold much more quickly, so that droplets can't be formed. Credit: TU Eindhoven / Hans van Franeker  ... '

http://phys.org/news/2015-02-powder-efficiency-plastic-solar-cells.html
The efficiency of plastic solar cells can be doubled or tripled if an extra solvent is added during the production process, comparable with the role of baking powder in dough mixture. Exactly how this works has been unclear for the last ten years. But now researchers at Eindhoven University of Technology ...

This looks to be some interesting research.
More finely tuned cholesterol management will become an important medical treatment. Recently I was very surprised when a friend our ours who is very fit, well within their correct weight band. Does not smoke, nor drink much had high cholesterol. Not exactly a prime candidate for elevated cholesterol levels, so really confused by this. This is obviously a "deciding" factor in one's overall "good health" factor so interested to see how this research pans out.

【中國如何利用百度廣告攻擊github】

最近網路世界發生了一件很重大的事情。中國當局疑似透過知名中國廠商百度的廣告機制,對提供程式碼儲存的知名廠商github發動DDoS攻擊(阻斷服務攻擊,也就是用大流量癱瘓服務)。這次的攻擊,導致從3/18到3/27之間,對github的存取容易發生錯誤。

為何要攻擊github?這要從中國的防火牆說起。中國有防火牆,藉此屏蔽對中國不利的網站。有個名為Greatfire的網站因此幫助大家辨識哪些網站已遭到封鎖。另外,有些網站也會利用github的機制,將一些被封鎖的網站備份到github上,以方便中國民眾瀏覽。

中國曾多次嘗試封鎖github,但由於github上保存的程式碼是許多程式人員從業所需要的資料,也是目前資訊圈許多先進程式碼的存放位置,中國的封鎖引來包含李開復等許多資訊人員的抗議,因此難以封鎖。

既然很難封鎖,那麼把那些可能造成問題的內容幹掉應該就可以了吧?因此,中國這次的作法是,利用百度廣告的投放機制,引導世界各地的人在沒有察覺的狀況下攻擊github特定頁面。

百度的廣告會存取一個小小的Javascript程式(http://hm.baidu.com/h.js),這個程式存放在中國。如果在中國存取這個程式不會有問題,但如果從中國以外的地方存取,連線經過防火牆,就會出現攻擊「https://github.com/greatfire/」和「https://github.com/cn-nytimes/」的指令。

也就是說,如果你是中國以外地區的人,瀏覽了一個放入百度廣告的網頁,你的瀏覽器會收到一個變造過的網頁廣告程式碼,引導瀏覽器每兩秒攻擊一次這兩個github頁面。而且,攻擊流量來自於世界各地,就是沒有中國--中國會跟別人說,這絕不是中國網軍發動的攻擊。

這兩個網頁中,https://github.com/greatfire/ 是Greatfire 的頁面,而 https://github.com/cn-nytimes/ 則是紐約時報中文網的頁面。

後來,這兩個網頁只好暫時下架網頁內容,而以程式碼取代網頁內容。這個程式碼會彈出視窗,導致攻擊無法進行下去(如附圖)。

當然,嚴格來說,只能確定這次的攻擊應該是藉由百度廣告發動。但究竟是如何嵌入這些程式碼到百度廣告當中?有人認為可能是程式碼透過防火牆送出時,遭到防火牆嵌入或是替換,但目前已不得而知,中國政府與攻擊之間的關聯也難以證明。但看到被攻擊的網頁,很明顯可以知道得利者是中國當局。

這也是我們應該憂心的部分。中國可透過許多看似無害的公司,藉由這些公司投放的程式碼,達到攻擊異己,或是竊取資料的間諜行為。這次的事件只是冰山一角,未來可能還有更多攻擊,躲在我們不知道的地方。一不小心,我們都將成為發動攻擊的一份子。

【更正】經過本人測試,英國、美國、台灣訪問hm.baidu.com均指向IP 61.135.185.140,而該IP來自中國,因此並非存放於CDN的程式碼有問題,而是存取該檔案的連線通過中國防火牆時遭到竄改。

Does anyone know what does this icon in status bar in iOS mean?

I plugged in a bluetooth headphone, and it pops on status bar along with bluetooth.

I don't think airplay status icon look like this.
Is this the icon showing the power left in the headphone or not?

It's a old ipod touch 3rd gen

我只有吃生魚丼 醋飯跟魚肉的鮮度都不錯 3樣配菜,還蠻不錯的 另外比一般丼飯特別的是有pouched egg.糖心蛋,還蠻特別的 有次有買燒魚 這家店的燒烤品質也很好 喜歡團體小聚的人也可以來這裡,蠻多酒類的,啤酒為多,印象中似手也有幾 樣清酒 有18生喔
