The programming port of all the FP PLC’s support OPEN MEWTOCOL-COM. This is very useful when you want to monitor PLC values/bits or to set PLC values or bits via your COMPUTER. You can use any language such as Basic, C, Pascal, Assembler or even if other suppliers of PLCs can send ASCII Strings, they can talk to our PLCs to exchange data.
shc是一個(gè)加密shell腳本的工具.它的作用是把shell腳本轉(zhuǎn)換為一個(gè)可執(zhí)行的二進(jìn)制文件.
用shell腳本對(duì)系統(tǒng)進(jìn)行自動(dòng)化維護(hù),簡(jiǎn)單,便捷而且可移植性好.
但shell腳本是可讀寫的,很有可能會(huì)泄露敏感信息,如用戶名,密碼,路徑,IP等.
同樣,在shell腳本運(yùn)行時(shí)會(huì)也泄露敏感信息.
shc是一個(gè)加密shell腳本的工具.它的作用是把shell腳本轉(zhuǎn)換為一個(gè)可執(zhí)行的二進(jìn)制文件.
這就很好的解決了上述問題.
tar zxvf shc-3.8.tgz
cd shc-3.8
make test
make
make test
make Strings
make install 這一步需要root權(quán)限
使用方法:
shc -r -f script-name 注意:要有-r選項(xiàng), -f 后跟要加密的腳本名.
運(yùn)行后會(huì)生成兩個(gè)文件,script-name.x 和 script-name.x.c
script-name.x是加密后的可執(zhí)行的二進(jìn)制文件.
./script-name 即可運(yùn)行.
script-name.x.c是生成script-name.x的原文件(c語(yǔ)言)
PTypes (C++ Portable Types Library) is a simple alternative to the STL that includes multithreading and networking. It defines dynamic Strings, variants, character sets, lists and other basic data types along with threads, synchronization objects, IP sockets and named pipes. PTypes also offers message queues as an alternative method of thread synchronization. Its main `target audience is developers of complex network daemons, robots or non-visual client/server applications of any kind
an approach for capturing similarity between words that was concerned with the syntactic similarity of two Strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.

內(nèi)存管理程序，功能與FASTMM相似，PLEASE NOTE: There are two ways to install BigBrain. You may use the
memory manager code natively compiled into your EXE or you can use
an included external DLL which will allow you to share memory across
multiple DLLs with one central place for memory management. Using the DLL
allows your application to share Strings, and serves the same purpose
as the ShareMem unit included with Delphi. BigBrainShareMem.dll should
be 100％ compatible with the DelphiMM.dll and could even simply be renamed
to DelphiMM.dll to simplify deployment.
