寧提法門

寧提法門(別名:寧提、寧體、心髓、秘密心髓、密心髓、心中心)

寧提法門是寧瑪派大圓滿（阿底瑜伽）裡的最高修法。

寧提的定義

大圓滿（阿底瑜伽）本身可分為三部：心部、界部和竅訣部。熙日森哈大師進一步將竅訣部分成外、內、密、極密四類。總的竅訣部法門，尤其是其中的極密類，被稱為“寧提(秘密心髓、心中心)”法門。

Firefly-RK3288 Development Board To Support Android 4.4 and Lubuntu

 Add   RK32XX: Pipo P4 – 4.4.4 Edition                                                              2014/08/18 update

We’ve already got a long list of upcoming Rockchip RK3288 based Android media players, but no low cost development boards have been announced to date. We can certainly expect a Radxa Rock 2 board with the Cortex A17 processor, but it might not be the only one, as Firefly-RK3288 development board powered by Rockchip RK3288 is currently being developed by another Chinese team.

Android 5.0下載地址

Q：Android 5.0下載?Android 5.0下載地址?

A：那麼該系統是在今日淩晨Google IO 2014大會上正式發佈出來的，但是該系統現在還不支援下載，預計會等到明天率先支援Nexus 5或是Nexus 7進行系統更新，至於網路中合適支援下載現在還不清楚，但是估計不會讓用戶等太久的。

　　那麼明天的Nexus 5或是Nexus 7系統更新會直接提示到用戶的手機當中，不用再找網路位址進行下載。那麼Android 5.0作出以下更新和改變：

ODROID-XU3 Development Board

Remember ODROID-XU2 development board based on Exynos 5420? The bad news is that it apparently got scrapped, but the good news is that it gave birth to ODROID-XU3 development board powered by the latest Samsung Exynos 5422 octa core big.LITTLE SoC with support for Ubuntu 14.04 and Android 4.4, including GPU 3D acceleration with the company promising a full desktop experience in Ubuntu.

葡萄柚與43種藥併服恐猝死

大多數人生病領藥時，醫師都會提醒吃藥記得配溫開水，勿搭配果汁，特別是葡萄柚汁，以免藥效受到影響。發表於「加拿大醫學會期刊」（Canadian Medical Association Journa）的最新研究則進一步發現，隨著近年來許多新藥物的研發，葡萄柚的副作用也大增，在85種可與葡萄柚產生作用的藥物中，有43種具有危險性，嚴重甚至可能出現猝死、腎衰竭的問題。

根據美國《ABC NEWS》新聞網報導，在20年前首次發現藥物與葡萄柚會產生危險副作用的研究團隊，接下來在2008~2012年期間，也持續針對不斷上市的新藥物做研究，並發現服藥配葡萄柚會導致嚴重反應的藥物數量，從17種大增至43種，其中包括降膽固醇用的藥物阿托伐他汀（atorvastatin）、羅瓦斯達汀（lovastatin）、素果膜衣錠（simvastatin），以及部分癌症與心臟用藥。

豆花DIY

鹽與豆花，看似八竿子打不著關係的兩個東西，實際上卻息息相關。

先來說說怎麼做豆花好了。首先你需要的是無糖豆漿，(用磨豆漿機)。

然後你做點處理，豆漿就可以變成豆花了。如果你撈起來瀝乾加壓去水，還可以變成豆腐哩！

Wireshark with EtherCAT debug

EtherCAT

EtherCAT is an open, high performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. The EtherCAT protocol is optimised for process data and is transported directly within the standard IEEE 802.3 Ethernet frame using Ethertype 0x88a4. It may consist of several sub-datagrams, each serving a particular memory area of the logical process images that can be up to 4 gigabytes in size. The data sequence is independent of the physical order of the nodes in the network; addressing can be in any order. Broadcast, multicast and communication between slaves are possible. If IP routing is required, the EtherCAT protocol can be inserted into UDP/IP or TCP/IP datagrams. This also enables any control with Ethernet protocol stack to address EtherCAT systems.

Build EtherLAB master kernel

http://taste.tuxfamily.org/wiki/index.php?title=Build_EtherLAB_master_kernel

Etherlab

EtherLAB developed an EtherCAT master software that runs as a Linux kernel module. As a result, it is far faster than user-space implementation. However, building the Ethercat Master implementation with a Linux kernel requires to build it using the appropriate kernel version. As we build it with PREEMPT-RT, we shall have the appropriate version for the kernel, the PREEMPT-RT patch and Etherlab. It seems that the 2.6.33 release of the kernel meet these requirements.

IEC 61800-7

Die IEC 61800-7 ist eine internationale Norm für eine universelle Schnittstelle für einen Antrieb mit variabler Drehzahl mit dem Titel "Generic interface and use of profiles for power drive systems". Sie wird von der International Electrotechnical Commission (IEC) herausgegeben. In der Norm wird diese abstrakte, universelle Schnittstelle auf vier unterschiedliche Antriebsprofile abgebildet und diese werden wiederum auf unterschiedliche Kommunikationsprofile von Feldbussen undindustriellem Ethernet abgebildet.

Win 7停止支援倒數!!!

微軟今年4月停止支援Windows XP，成功帶動企業換機潮，讓個人電腦（PC）市場今年看到回春的跡象。不知是否食髓知味，近日再傳微軟將在明年1月13日前，停止對Windows 7的主流支援服務，延伸支援則到2020年。

Using WinPcap in C# (Packet capture)

WinPcap is a very useful tool which can enables users to capture windows packets. On their website they offer a development pack but only for C/C++ programmers. So this is why I decided to write my own (simple) class for capturing packets in C# importing the wpcap.dll . Before showing the code, you must know that in order for your program to run as it should in Windows Vista/7 you must run it as administrator, otherwise it won’t even find the (network) devices.

LinuxCNC with EtherCAT

1)EtherCAT realtime HAL driver

Overview

This driver tries to provide an easy-to-expand framework for the connection of LinuxCNC to EtherCAT devices. Some of the often used Beckhoff devices like digital and analog I/O, encoder input and pulse train output are already supported just as the [Stöber] MDS5000 series of servo drives. The driver is based on [IgH's EtherCAT master] and builds a glue layer like the etherlab component. It consists of an userspace component for configuration and a RT HAL module for the data processing.

The config module reads in and parses a xml config file and provides a prepared form of configuration data via shared memory to the RT part. The RT module is organised in a global part that is common to all submodules and a .c and .h file for each supported (class off) hardware device.

Since this driver is sill under development you can find the code [here]. Feel free to test or review the code and send me suggestions and hints. There is a discussion thread about this driver in the [forum].
