i need collect logs devices firewall, printers, routers, switches, proxy-servers, mail-servers, db-server, anti-virus software , other softwares both linux , windows platform. able single open-source tools syslog-ng ? there other similar or different open-source logging tool can serve purpose single-handedly? mostly depends on other devices. if can send logs in standard syslog (rfc3164 or rfc5454), syslog-ng can receive them. depending on devices, can install syslog-ng client , collect logs files if needed. for windows, need other tool can collect logs windows eventlog , forward syslog logserver syslog-ng can receive them. there both free , commercial tools can (for example, commercial version of syslog-ng).

i have string want split 2-digit pieces. tried using regex so: import re s = "123456789" t = re.sub('..', ".. ", s) print(t) i expected 12 34 56 78 9 instead got '.. .. .. .. 9' . 9 not bother me, because know have number of digits, how can tell re.sub not replace actual digit dot? using python shell 3.5.1 edit checked 3 answers, , work, findall seems faster (and more elegant imo ;p ): import time import re s = "43256711233214432" = 10000 start = time.time() while i: -= 1 re.sub('(..)', r"\1 ", s) end = time.time() elapsed = end - start print("using r\"\\1 \" : ", elapsed) = 10000 start = time.time() while i: re.sub('..', r"\g<0> ", s) -= 1 end = time.time() elapsed = end - start print("using r\"\g<0> \" : ", elapsed) = 10000 start = time.time() while i: ' '.join(re.findall(r'..|.', s))

i have page listing customers: /customers/ the order of customers on page not sequential: 1st: id 111 2nd: id 567 3rd: id 345 etc that's because sql query lets user select customer order based on first name, last name, or nickname. "select customer_id customers status = 1 order " . $customer_order so when on 2nd customer in example above: /customer/567/ so problem want display previous , next button this, can't figure out how: <a href="111">prev</a> <a href="567">current</a> <a href="345">next</a> i managed previous link working in while loop it's ugly. tried using current(), prev(), , next() failed. most solutions i've seen on stackoverflow sequential ids either -1 or 1 current id, or "limit 1" in query i'm sure doesn't work in situation after testing this. any ideas? you can assign row number query , use row number identify previous , next

we know c doesn't support operator overloading.can tell me if so, how able use less sign in #include directive , in comparison also? or functionality provided called else , defined in language? many symbols in c have different meaning depending on context. example: * can mean either multiplication or pointer dereference. such dual meanings makes bit tricky write c parser , trickier provide helpful error messages when code doesn't compile. note dual meaning not operator overloading. 2 separate operators. when comes #include directives answer processed pre-processor. after pre-processor step < , > gone - line has been replaced entire contents of include file.
