常用國道無線電頻率
http://www.jcradio.com.tw/article/state-road-radio
業餘無線電使用頻率中，法定的使用頻率範圍在VHF 144.000~146.000MHz之間、UHF
430.000~432.000MHz之間。無線電使用人數已經不如以往，在法定的範圍有執照的業餘玩家都能夠自由使用，為了達到最有效率的通訊，長期以來經過無線電玩家呼籲以及使用習慣，逐漸在一些特別常用到的場合中，會使用特定的頻率來聯絡。
另外除了 145.000MHz 與 431.000MHz 為法定緊急呼叫及遇到重大災害時所使用的緊急頻道，業餘使用者必須避免長時間聊天占用。以下提供一些經常會使用的國道頻率，給初入門的業餘玩家參考：
143.690 MHz 中部橫貫公路
143.800 MHz 平面道路交通路況
143.870 MHz 北宜公路
144.880 MHz 國道一號
146.990 MHz 蘇花公路
430.780 MHz 國光客運(中山高)
430.780 MHz 國光客運(中山高)

android marshmallow v6.0.1 wifi peap/ 紅米note miui 6 developer mode/option
https://forums.oneplus.net/threads/workaround-for-one-plus-one-after-updated-to-android-marshmallow-v6-0-1-fail-to-connect-wifi-peap.445078/
1. Turn on developer mode through multiple tap on About -> Build. (search for "enable developer mode/option", if you not get what I mean)
2. Go into developer option, look for "Use Legacy DHCP client - Use the DHCP client from Lollipop instead of the new Android DHCP client", and turn it On.
3. On your wifi again, it should be able to connect to your office / work wifi network with PEAP connection.

1)設定>關於手機>然後係miui 版本點擊數下, 直至話你已是開發人員了.
2)跟住返回上一頁(設定首頁)>其他進階設定(additional setting)>就會見到開發人員選項(Developer options).

為利使用者識別可否使用無線網路漫遊交換機制，請加入漫遊中心的單位於新增或者修改SSID名稱為TANetRoaming。
備註:
SSID(Service Set Identifier)指的是提供無線網路功能的服務組其定義一個識別代號，簡單來說指的就是無線網路識別名稱。

su 檔案 gcc gnu
在build code時除了有 .o檔案外 還有 .su檔案 (stack used)
https://gcc.gnu.org/onlinedocs/gnat_ugn/Static-Stack-Usage-Analysis.html
6.6.2 Static Stack Usage Analysis
A unit compiled with-fstack-usage will generate an extra file
that specifies
the maximum amount of stack used, on a per-function basis.
The file has the same
basename as the target object file with a .su extension.
Each line of this file is made up of three fields:
- * The name of the function.
- * A number of bytes.
- * One or more qualifiers: static, dynamic, bounded.
The qualifier static means that the function frame size is purely static. It usually means that all local variables have a static size. In this case, the second field is a reliable measure of the function stack utilization.
The qualifier dynamic means that the function frame size is not static. It happens mainly when some local variables have a dynamic size. When this qualifier appears alone, the second field is not a reliable measure of the function stack analysis. When it is qualified with bounded, it means that the second field is a reliable maximum of the function stack utilization.
A unit compiled with
-Wstack-usage will issue a warning for each
subprogram whose stack usage might be larger than the specified amount of
bytes. The wording is in keeping with the qualifier documented above.2017年6月22日 星期四
google sheet 試算表排序 (multiple columns)
http://www.wikihow.com/Sort-by-Multiple-Columns-in-Google-Spreadsheets
Google Spreadsheets are an effective way to store and manage data, and have many of the capabilities of popular spreadsheet applications like Microsoft Excel. In addition, Google Spreadsheets make it easy to collaborate with others on the the same documents. Despite their power and flexibility, it's not always intuitive for Excel users to figure out how to do some basic tasks in Google Spreadsheets, such as sorting by multiple columns. Unlike Excel, you can only sort by a single column at a time; this limitation requires you to take a different approach to sorting if you want to organize by multiple columns. Read on to learn how.
Input your data in your spreadsheet.
Decide what order you'd like to sort your information. For the purposes of this example, assume we want to to have the people in the list grouped by city, then last name, then first name.
Sort by the least important, smallest or most narrow grouping in your sort order. In this case, that would be the column with first names. Click on "sort range" then choose if "A-Z" or "Z-A" and press "Sort"
Sort by the next grouping in your sort order. In this case, that would be the column with last names.
Continue sorting by increasingly larger or more important groups in your sort order until you have the list organized as you would like.

http://kevinjiang.info/2016/01/21/Xshell%20emacs%20发送alt键/
默认在Xshell里面使用emacs的时候，Alt键是不怎么好用的，其实是没有发送到服务器端的，所以需要对其他做一个设置：
File -> Properties -> Terminal -> Keyboard
把Use Alt as Meta key这个选项勾上

Re: Problems with keyboard shortcuts using ALT key
Modify Delete
Hi,
Try the "Use Alt as Meta Key" option on Session Properties->Terminal tab->Advanced Options->Emacs Compatibility.
Also You may use Esc instead of the Alt key in yast.
