大資料處理平台與案例

大資料能夠在國内得到快速發展,甚至是國家層面的支援,最為重要的一點就是我們純國産大資料處理技術的突破以及跨越式發展。在網際網路深刻改變我們的生活、工作方式的當下,資料就成為了最為重要的資料。尤其是資料安全問題就更為突出,前階段的Facebook使用者資料洩漏所引發産生的一系列問題,就充分的說明了資料安全問題的嚴重性。大資料發展的必然趨勢就是将會深刻改變我們的工作和生活方式,無論是企業還是個人也都必然會成為其中的一個“資料”。選擇什麼樣的大資料處理,不僅僅考慮是簡單、易用,更重要的是能夠確定資料的安全!

目前國内的hadoop大資料處理平台可以說是比較雜亂的,有國外的、有在國外版本基礎上二次開發,卻很少有做原生态開發的。而至于做原生态開發的,目前已知也就是大快搜尋了。是以,個人一直很喜歡大快搜尋産品手冊封面上的一句話:讓每個程式員都能開發大資料 底層技術從此觸手可及!在這裡我也是直接把大快搜尋的手冊封面圖拿來了做了文章的封面。

大資料可以說是從搜尋引擎誕生之處就有了,我們熟悉的搜尋引擎,如百度搜尋引擎、360搜尋引擎等可以說是大資料技處理技術的最早的也是比較基礎的一種應用。大概在2015年大資料都還不是非常火爆,2015年可以說是大資料的一個分水嶺。随着網際網路技術的快速發展,大資料也随之迎來它的發展高峰期。

整個大資料處理技術的核心基礎hadoop、mapreduce、nosql系統,而這三個系統是建立在谷歌提出的大表、分布式檔案系統和分布式計算的三大技術構架上,以此來解決海量資料處理的問題。雖然說大資料處理技術最早興起于國外,但就目前大資料處理技術的應用還是我們國内做的要比較好。從近兩年國家對大資料的扶持力度,我們可以很明顯的感覺到大資料正在與我們的生活、工作深刻的結合。

大資料處理平台與案例

大資料的應用開發一直是過于偏向底層,面臨的問題就是學習難度大,所涉及的技術面也是非常廣泛,這在很大程度上了制約了大資料的普及,這也是大部分大資料處理平台都面臨的突出問題。大快搜尋所推出的大資料一體化開發架構基本上是很好的解決了這樣的問題。它把大資料開發中的一些通過的,重複使用的基礎代碼、算法封裝為類庫,降低了大資料的學習門檻,降低了開發難度,很好的提高了大資料項目的開發效率。大快的一體化開發架構由資料源與SQL引擎、資料采集(自定義爬蟲)子產品、資料處理子產品、機器學習算法、自然語言處理子產品、搜尋引擎子產品,六部分組成。采用類黑箱架構模式,使用者直接調用大快的相關類即可完成,過去複雜的編碼工作。

大快的大資料通用計算平台(DKHadoop),已經內建相同版本号的開發架構的全部元件。關于DKhadoop大資料處理平台的案例,其實感興趣的可以去大快的網站上查詢一下,裡面有很多案例分享。個人所知的是DKhadoop的政務大資料處了解決方案非常好!大家也可以在大快網站上查詢一下這方面的方案資料。

What is the difference between 180cm and 160cm? The mechanism of human growth and height has been revealed

The height of a person depends mainly on the length of the long bones (femur of the lower extremities, tibia). The growth of long bones includes the longitudinal growth of bones and the maturity of bones (to put it bluntly, the length of the legs).

Human bones begin to form as early as february of gestational age. After that, as the process of growth and development continues to grow larger and thicker, the bones of women do not stop growing until they are about sixteen years old, and men grow to about eighteen years old.

What is the difference between 180cm and 160cm? The mechanism of human growth and height has been revealed

At the junction of the developing bone and the backbone, there is a thin layer of cartilage called a growth plate. The cartilaginocytes continue to divide to form new cartilage, which is then replaced by hard real bone, so that the bone can grow. Long bones grow longitudinally little by little, and their height continues to increase, just like sesame blossoms.

How to fight for another 15cm tall space for children?

The final height of the human body depends on the situation that the body growth plate is closed, and if the growth plate is closed, the epiphyseum is closed, indicating that the bone has matured, the bone no longer grows, and the person no longer grows tall.

Geneticists say that the boy's adult lifetime height (cm) = (father's height + mother's height + 13) / 2±7.5 (cm)

The adult lifetime height (cm) of the girl = (father height + mother height - 13) / 2 ±7.5 (cm), that is, there is a 15 cm increase space between the minimum value of the child's height and the peak of the peak.

So how do you complete the height limit of 15cm before the growth plate is closed?

What is the difference between 180cm and 160cm? The mechanism of human growth and height has been revealed

What factors affect a person's height?

People gradually grow taller during growth, which is the result of bone growth and development, and is mainly manifested in the growth of lower limb bones and vertebrae.

The growth of the bones (legs) of the lower extremities is formed by the growth plates of the femur and tibia. The growth plate is located at both ends of the bone, stimulated by the growth hormone secreted by the pituitary gland, which will continue to proliferate cartilage, and the newborn cartilage will be calcified to form hard bone, so that the bone becomes longer and wider.

Therefore, the growth hormone secreted by the pituitary gland is the premise and basis for growing tall!

Growth hormone is secreted in a pulsed manner, its secretion is regulated by the growth hormone releaser produced by the hypothalamus, but also affected by gender, age and circadian rhythm, many human hormones are secreted at night from 11:00 to 2:00 a.m. Therefore, insufficient sleep time and low quality will affect height growth.

To ensure the normal secretion of growth hormone, first of all, good sleep off!

Many children have phenomena such as restless nights at night, turning over and over, which affect the quality of children's sleep, and then affect the height growth of children.

So how to ensure the quality of your child's sleep?

Children lie restless at night, sleep over and over, in Traditional Chinese medicine is a typical manifestation of spleen and stomach disharmony, starting from the root, strengthening the child's spleen and stomach is the key to ensuring sleep, but also the most critical step for children to grow tall!

Protein is the foundation of life, and the proliferation of bone cells and the development of muscles and organs are inseparable from protein. After the protein in the food enters the human body, it is digested and first decomposed into amino acids, and then the human body uses these amino acids to synthesize new human proteins. In the synthesis of protein of various amino acids, L-lysine is the most important one, without it, other amino acids are limited or can not be used, in turn, the human body only supplemented with enough L-lysine to improve the absorption and utilization of food proteins, to achieve balanced nutrition, promote growth and development.

In summary, in addition to 60% of the genetics of children growing tall, sleep quality, protein absorption, and lysine protection are the keys for children to reach the peak of height!

Multiple efforts to help children grow taller

Pediatric spleen patch, with acupuncture into the medicine, through pure Chinese medicine drugs to directly stimulate acupuncture points, and through transdermal absorption technology, directly to the lesion, fundamentally enhance the child's spleen and stomach function, so that the child's spleen and stomach to restore to the best state.

The stomach division accepts, the spleen division transports, one absorbs one luck, transforms the essence, provides for the whole body, and maintains the life activities of the body. A strong spleen and stomach ensure the quality of sleep, promote the function of the pituitary gland to secrete growth hormone, and provide the driving force for the growth plate to continuously form new cartilage, thereby ensuring the normal growth of bones.

Bazhen grows loosely, strengthens the spleen and appetizes, enhances the body's ability to transport and absorb nutrients, reserves enough protein, and ensures that the body normally decomposes the L-lysine needed for growth and development.

A large number of experiments have proved that enough lysine can stimulate the pituitary gland to increase the secretion of interleukins, and under the action of lysine, the biomolecular indicators related to bone growth produced and secreted by bone cells are significantly increased. Lysine generates bone elements to ensure the sufficiency of lysine in the child's body, thereby improving the absorption and utilization of food proteins, and doing a good job as a reserve army for body growth!

Breaking the genetic determinism, 160cm is by no means the final height of a child!
