`entr`: How is update ID'd? noatime troubles? &, why -r not work with -d?

问题 I have a script regularly appending to a log file. When I use entr (discovered here) to monitor that log file, and I then touch the log, everything works fine, but when the script appends to the file, entr fails. This may be because I have noatime set in my fstab - but that only stops the updating of the access time not the modify time, so this confuses me. I've checked and while atime is not updating, ctime ( ls -lc ) definitely is. Could entr really be depending on atime? I use noatime

Convert ctime to unicode and unicode to ctime python

由 拈花ヽ惹草 提交于 2019-12-11 02:46:34
问题 I have converted a ctime value to unicode 1295478503.6789999 to 'Wed Jan 19 18:08:23 2011' Can I go backwards? From the second line to the first? 回答1: You want the Python time module, specifically the strptime() function. (How'd you convert from ctime to unicode/string? Probably with time.strftime(). So it makes sense to look for the inverse direction of that, which is time.strptime().) Here's a good Google query for this, too: http://www.google.com/search?q=python+parse+time+string Sample:

Is There an Upper Bound in my locale for Time Related Information?

由 别等时光非礼了梦想. 提交于 2019-12-11 02:39:32
问题 Is there a definition somewhere in the standard namespace that sets forward: Months in a year Days in a week Hours in a day Minutes in an hour Seconds in a minute The struct tm has contains member variables that must be in these ranges, but I can't find the defined limits anywhere. I'm not even sure if there are locales defined where these wouldn't match the conventional set (12/7/24/60/60). Even if there aren't potential users with other range limits, I'd sure like to use a define from the

Initializing static struct tm in a class

由 ぃ、小莉子 提交于 2019-12-10 15:27:53
问题 I would like to use the tm struct as a static variable in a class. Spent a whole day reading and trying but it still can't work :( Would appreciate if someone could point out what I was doing wrong In my class, under Public, i have declared it as: static struct tm *dataTime; In the main.cpp, I have tried to define and initialize it with system time temporarily to test out (actual time to be entered at runtime) time_t rawTime; time ( &rawTime ); tm Indice::dataTime = localtime(&rawTime); but

How to fix missing time related no member in global namespace errors on MacOSX?

问题 I'm trying to compile a project on the command line on Maverick 10.9. The project compiles perfectly on Linux. Apparently, there seems to be an issue with ctime on MacOSX.

【原创】Python处理海量数据的实战研究

由 六月ゝ 毕业季﹏ 提交于 2019-12-08 19:20:41
最近看了July的一些关于Java处理海量数据的问题研究，深有感触，链接： http://blog.csdn.net/v_july_v/article/details/6685962 感谢July ^_^ 他用的是Java的Hash Map等方法做了处理，讲解的非常深刻入骨 我也一时兴起，想拿Python试试刀，看看Python对于海量数据的处理能力如何。无奈在百度和Google输入“Python 海量数据”都无果。可能是国内使用python的不多，用python处理海量数据的就更少了。不过这浇灭不了我的欲望，哈哈 打算拿July的其中一个问题来试验一下： 海量日志数据，提取出某日访问百度次数最多的那个IP。 July给出的解决方案： 方案1：首先是这一天，并且是访问百度的日志中的IP取出来，逐个写入到一个大文件中。注意到IP是32位的，最多有2^32个IP。同样可以采用映射的方法，比如模1000，把整个大文件映射为1000个小文件，再找出每个小文中出现频率最大的IP（可以采用hash_map进行频率统计，然后再找出频率最大的几个）及相应的频率。然后再在这1000个最大的IP中，找出那个频率最大的IP，即为所求。 下手吧！ （一）生成数据 我首先构造1亿个IP，这些IP前两段都是“10.197”，后两段为0-255的随机数 把这1亿个IP存入一个文本文件中 Python代码如下：

c/c++ microsecond timestamp

由 妖精的绣舞 提交于 2019-12-08 07:52:37
问题 I used this piece of code to get timestamp in microsecond in c/c++. but it doesn't look like microsecond. also i don't know if there is any way to format it. timeval curTime; gettimeofday(&curTime, NULL); int milli = curTime.tv_usec / 1000; unsigned long micro = curTime.tv_usec*(uint64_t)1000000+curTime.tv_usec; char buffer [80]; //localtime is not thread safe strftime(buffer, 80, "%Y-%m-%d %H:%M:%S", localtime(&curTime.tv_sec)); char currentTime[84] = ""; char currentTime2[80] = ""; sprintf

问题 I am reading a datetime from database in a ColeDateTime format. I want to convert it to CTime to get the date month year and time. CString repDt; //**this will hold the datetime which i read from Database** COleDateTime dt; //**my datetime format is mm/dd/yyyy.** dt.ParseDateTime(repDt); **//this line of code gives exception** CTime t(dt.GetYear(), dt.GetMonth(), dt.GetDay(), dt.GetHour(), dt.GetMinute(), dt.GetSecond()); m_time=t.GetTime(); Please give me some solution how could I do this?

Convert historical time to GMT

由 痴心易碎 提交于 2019-12-07 19:37:53
问题 I need to convert some string times in the format "2011061411322100" into GMT - my first attempt is below. However, the problem is that the times are coming from another PC and is a historical time. So I am not getting the times in real time so I cannot simply get the GMT from the local time on the box that my code is running. The problem is that if my code is running during a time change, the time change will have occurred on my box but not on the remote box where I am getting the times. I
