土法煉鋼 - 合併兩張eps圖檔

在fedora　執行gimp

開啟你要合併的那兩個檔案(A,B)

然後再新增一個檔案　設定尺寸大小　直接把A,B的圖案複製過去

再另存新檔成eps

收工 XD

在soekris net4521安裝 openwrt

超級無敵簡單　囧

去抓
openwrt-x86-2.6-jffs2-128k.image
openwrt-x86-2.6-jffs2-64k.image
openwrt-x86-2.6-ext2.image

看你喜歡哪一種檔案系統　就裝哪一個　(我是用ext2那個)

http://kamikaze.openwrt.org/7.09/x86-2.6/　這邊可以抓


然後把你的CF卡接到linux電腦上　直接用dd複製就好了　(記得改成你的CF卡位置)

dd if=openwrt-x86-2.6-ext2.image of=/dev/sdX

然後接上去就可以開機了

只是他們的console baud rate 是 38400
Soekris BIOS好像是 19200

可是開機後我要做啥啊　囧

查詢學校發表paper篇數

1. 進入Web of Science

http://isiknowledge.com/?DestApp=WOS

(1). Publication name 輸入期刊名稱,
ex: IEEE Transactions on Vehicular Technology

(2). Timespan 選全部年份 之後再作篩選
(別人的心得 不要問我為什麼 XD)

(3). Citation Databases: 選前兩個就好 (其實我也不確定 -.-)
Science Citation Index Expanded (SCI-EXPANDED) --1977-present
Social Sciences Citation Index (SSCI) --1977-present

2. 篩選搜尋結果

(1). 左邊有個Publication Years
按下去展開後有一個"more options / values... "
然後按more options去篩選你要的年份

選完後按"refine"

(2). 然後再按左邊的Institutions 一樣按more options
就可以看到所有學校的發表篇數
NCTU= NATL CHIAO TUNG UNIV
選完後按"refine"

搭配(1),(2)就可以查出每個學校在每一年分別有幾篇paper


如果要再細分系所 只能一個一個點進去看 然後用人腦演算法去判別 XD

iperf - 測速率軟體

iperf --help
Usage: iperf [-s|-c host] [options]
iperf [-h|--help] [-v|--version]

Client/Server:
-f, --format [kmKM] format to report: Kbits, Mbits, KBytes, MBytes
-i, --interval # seconds between periodic bandwidth reports
-l, --len #[KM] length of buffer to read or write (default 8 KB)
-m, --print_mss print TCP maximum segment size (MTU - TCP/IP header)
-p, --port # server port to listen on/connect to
-u, --udp use UDP rather than TCP
-w, --window #[KM] TCP window size (socket buffer size)
-B, --bind bind to , an interface or multicast address
-C, --compatibility for use with older versions does not sent extra msgs
-M, --mss # set TCP maximum segment size (MTU - 40 bytes)
-N, --nodelay set TCP no delay, disabling Nagle's Algorithm
-V, --IPv6Version Set the domain to IPv6

Server specific:
-s, --server run in server mode
-U, --single_udp run in single threaded UDP mode
-D, --daemon run the server as a daemon

Client specific:
-b, --bandwidth #[KM] for UDP, bandwidth to send at in bits/sec
(default 1 Mbit/sec, implies -u)
-c, --client run in client mode, connecting to
-d, --dualtest Do a bidirectional test simultaneously
-n, --num #[KM] number of bytes to transmit (instead of -t)
-r, --tradeoff Do a bidirectional test individually
-t, --time # time in seconds to transmit for (default 10 secs)
-F, --fileinput input the data to be transmitted from a file
-I, --stdin input the data to be transmitted from stdin
-L, --listenport # port to recieve bidirectional tests back on
-P, --parallel # number of parallel client threads to run
-T, --ttl # time-to-live, for multicast (default 1)

Miscellaneous:
-h, --help print this message and quit
-v, --version print version information and quit

[KM] Indicates options that support a K or M suffix for kilo- or mega-

The TCP window size option can be set by the environment variable
TCP_WINDOW_SIZE. Most other options can be set by an environment variable
IPERF_, such as IPERF_BANDWIDTH.
