  • Correct way to do timer function in Python

    - by bwawok
    Hi. I have a GUI application that needs to do something simple in the background (update a wx python progress bar, but that doesn't really matter). I see that there is a threading.timer class.. but there seems to be no way to make it repeat. So if I use the timer, I end up having to make a new thread on every single execution... like : import threading import time def DoTheDew(): print "I did it" t = threading.Timer(1, function=DoTheDew) t.daemon = True t.start() if __name__ == '__main__': t = threading.Timer(1, function=DoTheDew) t.daemon = True t.start() time.sleep(10) This seems like I am making a bunch of threads that do 1 silly thing and die.. why not write it as : import threading import time def DoTheDew(): while True: print "I did it" time.sleep(1) if __name__ == '__main__': t = threading.Thread(target=DoTheDew) t.daemon = True t.start() time.sleep(10) Am I missing some way to make a timer keep doing something? Either of these options seems silly... I am looking for a timer more like a java.util.Timer that can schedule the thread to happen every second... If there isn't a way in Python, which of my above methods is better and why?

  • Is there something like clock() that works better for parallel code?

    - by Jared P
    So I know that clock() measures clock cycles, and thus isn't very good for measuring time, and I know there are functions like omp_get_wtime() for getting the wall time, but it is frustrating for me that the wall time varies so much, and was wondering if there was some way to measure distinct clock cycles (only one cycle even if more than one thread executed in it). It has to be something relatively simple/native. Thanks

  • python logparse search specific text

    - by krisdigitx
    hi, I am using this function in my code to return the strings i want from reading the log file, I want to grep the "exim" process and return the results, but running the code gives no error, but the output is limited to three lines, how can i just get the output only related to exim process.. #output: {'date': '13', 'process': 'syslogd', 'time': '06:27:33', 'month': 'May'} {'date': '13', 'process': 'exim[23168]:', 'time': '06:27:33', 'month': 'May'} {'May': ['syslogd']} #function: def generate_log_report(logfile): report_dict = {} for line in logfile: line_dict = dictify_logline(line) print line_dict try: month = line_dict['month'] date = line_dict['date'] time = line_dict['time'] #process = line_dict['process'] if "exim" in line_dict['process']: process = line_dict['process'] break else: process = line_dict['process'] except ValueError: continue report_dict.setdefault(month, []).append(process) return report_dict

  • Is System.nanoTime() consistent across threads?

    - by obvio171
    I want to count the time elapsed between two events in nanoseconds. To do that, I can use System.nanoTime() as mentioned here. The problem is that the two events are happening in different threads. Since nanoTime() doesn't return an absolute timestamp but instead can only be used to calculate time differences, I'd like to know if the values I get on the two different threads are consistent with the physical time elapsed between the two events.

  • Rendering another Action without changing URL?

    - by Michael Stum
    I have this code in my Rails 3 controller: def index now = Time.now.utc.strftime("%m%d") redirect_to :action => "show", :id => now end def show begin @date = Time.parse("12#{params[:id]}") dbdate = params[:id] rescue ArgumentError @date = Time.now.utc dbdate = @date.strftime("%m%d") end @date = @date.strftime("%B %d") @events = Event.events_for_date(dbdate) end So basically index is just a specialized version of show, hence I want it to execute show, render the show.html.erb view - but I do not want to change the URL like redirect_to does. I have tried this approach: def index now = Time.now.utc.strftime("%m%d") params[:id] = now show render :action => "show" end Now, this works, but it just smells badly. I'm new to Ruby and Rails, so I just wonder if there is something fundamentally wrong or if there is a better way to do this?

  • How to Track Number of Changes Occured in a Column? T-SQL - SQL Server

    - by user327387
    For example, i have a column named EmployeeName. Every time a user changes/fix his name, i need to keep a count. If he changes his name twice, then count is 2. Also, i need to store the time of every change employee makes on EmployeeName e.g. if the name essentially is James and time created is 9:00 AM and then employee changes to John on 11:00 AM, i need to preserve this new time and new value as well as the previous one which is James at 9:00 AM. I hope its clear! Thank you guys...Best Answer will be chosen... If this requires a trigger, giving a sketchy pseudo-code will be very much appreciated.

  • Should I ignore the occasional Invalid viewstate error?

    - by Richard Ev
    Every now and then (once every day or so) we're seeing the following types of errors in our logs for an ASP.NET 3.5 application Invalid viewstate Invalid postback or callback argument Are these something that "just happens" from time-to-time with an ASP.NET application? Would anyone recommend we spend a lot of time trying to diagnose what's causing the issues?

  • Can this loop be sped up in pure Python?

    - by Noctis Skytower
    I was trying out an experiment with Python, trying to find out how many times it could add one to an integer in one minute's time. Assuming two computers are the same except for the speed of the CPUs, this should give an estimate of how fast some CPU operations may take for the computer in question. The code below is an example of a test designed to fulfill the requirements given above. This version is about 20% faster than the first attempt and 150% faster than the third attempt. Can anyone make any suggestions as to how to get the most additions in a minute's time span? Higher numbers are desireable. EDIT: This experiment is being written in Python 3.1 and is 15% faster than the fourth speed-up attempt. def start(seconds): import time, _thread def stop(seconds, signal): time.sleep(seconds) signal.pop() total, signal = 0, [None] _thread.start_new_thread(stop, (seconds, signal)) while signal: total += 1 return total if __name__ == '__main__': print('Testing the CPU speed ...') print('Relative speed:', start(60))

  • Accessing the params hash for year and month rails and using in helper

    - by Matt
    So I took some php code and turned it into a calendar with a helper to make a simple calendar. I got my data from inside the helper: def calendar_maker a = Time.now b = a.month d = a.year h = Time.gm(d,b,1) #first day of month Now I want to try and do it with parameters within my method #from the helper file def calendar_maker(year, month) a = Time.now b = month c = year h = Time.gm(d,b,1) #first day of month #from my html.erb file <%= @month %> and <%= @year %> <%= params["month"] %><br /> <%= params["action"] %><br /> <%= params["year"] %><br /> <%= calendar_maker( @year, @month) %> #from controller file def calendar @month = params[:month] @year = params[:year] end Anyways mistakes were made and not finding documentation anywhere or not looking in the right place. How do I get this to work with my params hash. Thanks for the help.

  • Is it possible to plot a single density over a discrete variable?

    - by mattrepl
    The x-axis is time broken up into time intervals. There is an interval column in the data frame that specifies the time for each row. Plotting a histogram or line using geom_histogram and geom_freqpoly works great, but I'd like to use geom_density to get a filled area. Perhaps there is a better way to achieve this. Right now, if I use geom_density, curves are created for each discrete factor level instead of smoothing over all of them.

  • Changing new Tomcat settings from the defaults in STS Eclipse

    - by Ribeye
    I find myself continually having to delete my Tomcat 7 server in STS Eclipse and re-installing. Each time I have to then: a) increase start up time from 45 sec and b) increase Tomcat memory by adding something like this on the "VM Arguments" under the "Arguments" tab: "-XX:MaxPermSize=512m -XX:PermSize=512m -Xms256m -Xmx1024m -XX:-UseGCOverheadLimit" How do you change defaults for a) and b)? Google has plenty of info on changing these one time, but I want to change the defaults for a "new", and on this the search is coming up a blank. Thanks

  • SQL Server Query Question

    - by Lp1
    Running SQL Server 2008, and I am definitely a new SQL user. I have a table that has 4 columns: EmpNum, User, Action, Updatetime A user logs into, and out of a system, it is registered in the database. For example, if user1 logs into the system, then out 5 minutes later, a simple query (select * from update) would look like: EmpNum User Action Updatetime 1 User1 I 2010-01-01 23:00:00:000 1 User1 O 2010-01-01 23:05:00:000 I'm trying to query the Empnum, User, Action, I(in time), O(out time), and the total time.

  • Oracle TIMESTAMP w/ timezone data type confusion

    - by JuiceBox1337
    When would you use TIMESTAMP w/ timezone as opposed to TIMESTAMP w/ local time zone? When data is stored in a column of data type TIMESTAMP w/ local tz, the data is normalized to the database time zone, and the time zone displacement is not stored as part of the column data. When users retrieve the data, Oracle returns it in the users' local session time zone. Isn't that much more useful? I can't think of a reason why I'd want to use TIMESTAMP w/ timezone and get back some gobble gook with a UTC offset.

  • SQL Server deadlock issue

    - by George2
    Hello everyone, I am using SQL Server 2008 Enterprise. I am wondering whether dead lock issue is only caused by cross dependencies (e.g. task A has lock on L1 but waits on lock on L2, and at the same time, task B has lock on L2 but waits on lock on L1)? Are there any other reasons and scenarios which will cause deadlock? Are there any other way which will causes dead lock -- e.g. timeout (a S/I/D/U statement do not return for a very long time, and deadlock error will be returned) or can not acquire lock for a long time but not caused by cross-dependencies (e.g. task C needs to get lock on table T, but another task D acquire the lock on table T without releasing the lock, which causes task C not be able to get lock on table T for a long time)? thanks in advance, George

  • Maven + SSDM Build and Runtime Environment Automation

    - by Randy
    Preface: My Company, like most, has several run-time environments and several release versions which themselves are composed of different versions of various jars. For example, let us consider release versions 1.1, 1.2, and 1.3 of Software X, which may be deployed to a developer computer, testing, or production. Software-x-1.1 is itself composed of jarA-0.9.1 and jarB-0.7.5, but software-x-1.3 is composed of jarA-1.7.31 and jarB-0.8.1. Currently we use Spring's PropertyPlaceholderConfigurer to configure run-time variables (such as database credentials), however, properties also change with release versions. We also use Maven 2 POM version 4 to specify which versions of our code need to be used. We place the version numbers of our jars as properties within profiles (dev,test,prod) inside of the parent pom and then reference those version numbers in all project poms. As of right now, we have no way to specify which project versions pertain to a given release other than the most current one. Moreover, we deploy our run-time configurations to the SSDM pickup which then configures and creates the services defined by the built versions of our software. -- Questions: Is there any procedure/tool we can use to build our product by merely providing the run-time environment and version number? IE "build 1.1 dev"? Is there anyway we can store the required jar versions for each release build? We are currently versioning all files, including the parent pom, but merely versioning the parent pom does not record which release version is pertinent to that parent pom. What else can we do to further automate the process of builds? For example, if we could manage run-time configurations within the parent pom that would be a step in the right direction, but that seems like a violation of scope. Any tool outside of our framework is inconceivable at this point, but not in the far future. Summary: How can we automate our build process to the fullest extent without being error prone?

  • First Come, First Served process scheduling

    i have 4 processes: p1 - bursts 5, priority: 3 p2 - bursts 8, priority: 2 p3 - bursts 12, priority: 2 p4 - bursts 6, priority: 1 Assuming that all processes arrive at the scheduler at the same time what is the average response time and average turnaround time? For FCFS is it ok to have them in the order p1, p2, p3, p4 in the execution queue?

  • JApplet behaving unexpectedly

    - by JohnW
    import java.awt.Graphics; import java.awt.Image; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.JApplet; import javax.swing.Timer; public class CountingSheep extends JApplet { private Image sheepImage; private Image backgroundImage; private GameBoard gameBoard; private scoreBoard scoreBoard; public void init() { loadImages(); gameBoard = new GameBoard(sheepImage, backgroundImage); scoreBoard = new scoreBoard(); getContentPane().add(gameBoard); getContentPane().add(scoreBoard); } public void loadImages() { sheepImage = getImage(getDocumentBase(), "sheep.png"); backgroundImage = getImage(getDocumentBase(), "bg.jpg"); } } Update guys: Alright, first of all, thank you very much for all the help you've given so far (specifically creemam and Hovercraft Full of Eels), and your persistence. You've helped me out a lot as this is incredibly important (i.e. me passing my degree). The problem now is: The program works correctly when nothing but the GameBoard class is added to the JApplet, however, when I try to add the ScoreBoard class, both Panel classes do not show on the Applet. I'm guessing this is now down to positioning? Any ideas? EDIT: Gone back to the previously asked question Hovercraft, and found it was due to the layout of the contentPane and the order at with the components were added. Thanks to all of you so much. People like you make the development community a bit of alright.

  • Should I learn FLEX, is it a marketable enough?

    - by aceinthehole
    I haven been recently laid off and was considering what to learn in the down time while trying to get another job. I had heard that Adobe's FLEX was starting to become more in-demand, and have seen it increasingly on job postings. Has anyone else been successful (career wise) in learning FLEX? Is it worth spending time to learn FLEX to add a bullet point to a resume, and lead to a possible job or should time be spent else where?

  • Anyone NOT using a Web Framework? Why?

    - by tom
    I'm well aware of the many reasons to use a web framework. I'm just wondering whether anyone out there is using absolutely no web framework whatsoever to develop their web projects. I would really love to know the reason(s) why you're not using a web framework. For the sake of this discussion, your programming language of choice does not matter. Some possibilities for discussion: You don't hide behind an ORM. You don't rely on any sort of templating system. You think MVC is a really nice TLA but lacks an essential vowel or two. No need for any additional javascript framework tomfoolery. You just write as much code as possible in your native programming language(s). Summary of reasons thus far: Language learning opportunities. Specific performance reasons (write-intensive transaction processing). Seeking more nuanced control over your data and applications (less abstraction). You're building your own framework! Prove to yourself that you can succeed (or fail) just like the big framework-building gurus. Integration issues with unpopular/legacy technologies (exotic databases or protocols come to mind). Big company, lots of code, no talent nor buy-in present to move to a web framework. Some frameworks really lock you in and cannot perpetually grow along with your needs. These few black sheep don't make it easy to jump outside of the framework, write some custom code, and easily jump back in. When you finally escape the asylum, you'll never look back.

  • FLOT: How to make different colored points in same data series, connected by a line?

    - by Mega Matt
    Hi all, I think I may have stumbled onto a limitation of Flot, but I'm not sure. I'm trying to represent a single data series over time. The items' "State" is represented on the Y-Axis (there are 5 of them), and time is on the X-Axis (items can change states over time). I want the graph to have points and lines connecting those points for each data series. In addition to tracking an item's State over time, I'd also like to represent it's "Status" at any of the particular points. This I would like to do by changing the color of the points. What this means is a single item may have different Statuses at different times, meaning for a single data series I need a line that connects different points (dots) of different colors. The only thing I've seen so far is the ability to specify the color for all points in a given dataseries. Does anyone know if there's a way to specify colors individually? Thanks.

  • unix shell, redirect output but keep on stdin

    I'd like to have a shell script redirect stdout of a child process in the following manner Redirect stdout to a file Display the output of the process in real time I know I could do something like #!/bin/sh ./child > file cat file But that would not display stdout in real time. For instance, if the child was #!/bin/sh echo 1 sleep 1 echo 2 The user would see "1" and "2" printed at the same time

  • Python implementation of avro slow?

    I'm reading some data from avro file using the avro library. It takes about a minute to load 33K objects from the file. This seem very slow to me, specially with the Java version reading the same file in about 1sec. Here is the code, am I doing something wrong? import avro.datafile import avro.io from time import time def load(filename): fo = open(filename, "rb") reader = avro.datafile.DataFileReader(fo, avro.io.DatumReader()) for i, record in enumerate(reader): pass return i + 1 def main(argv=None): import sys from argparse import ArgumentParser argv = argv or sys.argv parser = ArgumentParser(description="Read avro file") start = time() num_records = load("events.avro") end = time() print("{0} records in {1} seconds".format(num_records, end - start)) if __name__ == "__main__": main()
