  • Minimal "Task Queue" with stock Linux tools to leverage Multicore CPU

    - by Manuel
    What is the best/easiest way to build a minimal task queue system for Linux using bash and common tools? I have a file with 9'000 lines, each line has a bash command line, the commands are completely independent. command 1 > Logs/1.log command 2 > Logs/2.log command 3 > Logs/3.log ... My box has more than one core and I want to execute X tasks at the same time. I searched the web for a good way to do this. Apparently, a lot of people have this problem but nobody has a good solution so far. It would be nice if the solution had the following features: can interpret more than one command (e.g. command; command) can interpret stream redirects on the lines (e.g. ls > /tmp/ls.txt) only uses common Linux tools Bonus points if it works on other Unix-clones without too exotic requirements.

  • Tools\addin's for formating or cleaning up xaml?

    - by cody
    I'm guessing these don't exist since I searched around for these but I'm looking for a few tools: 1) A tool that cleans up my xaml so that the properties of elements are consistent through a file. I think enforcing that consistence would make the xaml easier to read. Maybe there could be a hierarchy of what comes first but if not alphabetical might work. Example before: TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4" TextBox Grid.Column="1" Margin="4" Name="t2" Grid.Row="3" Example after: TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4" TextBox Name="t2" Grid.Row="3" Grid.Column="1" Margin="4" (note < / has been remove from the above since control seem to have issues parsing whe the after section was added) 2) Along the same lines as above, to increase readability, a tool to align properties, so from the above code example similar props would start in the same place. <TextBox Name="myTextBox1" Grid.Row="3" Grid.Column="1" Margin="4"/> <TextBox Name="t2" Grid.Row="3" Grid.Column="1" Margin="4"/> I know VS has default settings for XAML documents so props can be on one line or separate lines so maybe if there was a tool as described in (1) this would not be needed...but it would still be nice if you like your props all on one line. 3) A tool that adds X to the any of the Grid.Row values and Y to any of the Grid.Column values in the selected text. Every time I add a new row\column I have to go manually fix these. From my understanding Expression Blend can help with this but seem excessive to open Blend just to increment some numbers (and just don't grok Blend). Maybe vs2010 with the designer will help but right now I'm on VS08 and Silverlight. Any one know of any tools to help with this? Anyone planning to write something like this...I'm looking at you JetBrains and\or DevExpress. Thanks.

  • NPE annotation scenarios and static-analysis tools for Java

    - by alex2k8
    Here is a number of code snippets that can throw NullPointerException. 01: public void m1(@Nullable String text) { System.out.print(text.toLowerCase()); // <-- expect to be reported. } 02: private boolean _closed = false; public void m1(@Nullable String text) { if(_closed) return; System.out.print(text.toLowerCase()); // <-- expect to be reported. } 03: public void m1(@NotNull String text) { System.out.print(text.toLowerCase()); } public @Nullable String getText() { return "Some text"; } public void m2() { m1(getText()); // <-- expect to be reported. } Different people have access to different static-analysis tools. It would be nice to collect information, what tools are able to detect and report the issues, and what are failing. Also, if you have your own scenarious, please, publish them. Here my results FindBugs (1.3.9): 01: Parameter must be nonnull but is marked as nullable 02: NOT reported 03: NOT reported IntelliJ IDE 9.0.2 (Community edition): 01: Method invocation text.toLowerCase() may produce java.lang.NullPointerException 02: Method invocation text.toLowerCase() may produce java.lang.NullPointerException 03: Argument getText() might be null

  • Dynamic Data Extract Tools

    - by Kevin McGovern
    I've been searching around for a few weeks now for a tool that either is fully built or a direction of something I could build for dynamically extracting data via a web interface. Basically, what I'm looking for is a way to give users a list of all available data objects from our database and then let them pick ones from the list they'd like to view and set parameters then export the results to an excel file. Right now we're doing it purely with SQL statements but we have hundreds of objects so as you might imagine, those statements are really complex and prone to errors. It would be great if there was a tool available to do this or if someone had an idea of an easy way to organize this. Any help would be greatly appreciated. We've looked at BI tools like QlikView and Tableau but that is probably overkill for what we're trying to do. The open-source BI tools we've looked at seemed really primitive in their functionality. The other thing we looked at was MSAS (our DB is SQL Server) but I'd prefer something that was more database-agnostic and lived on a web server instead of on the database.

  • Tools for Automated Source Code Editing

    - by Steve
    I'm working on a research project to automatically modify code to include advanced mathematical concepts (like adding random effects into a loop or encapsulating an existing function with a new function that adds in a more advanced physical model). My question to the community is: are there are any good tools for manipulating source code directly? I want to do things like Swap out functions Add variable declarations wherever they are required Determine if a function is multiplied by anything Determine what functions are called on a line of code See what parameters are passed to a function and replace them with alternatives Introduce new function calls on certain lines of code Wherever possible just leaving the rest of the code untouched and write out the results I never want to actually compile the code I only want to understand what symbols are used, replace and add in a syntactically correct way, and be able to declare variables at the right position. I've been using a minimal flex/bison approach with some success but I do not feel the it is robust. I hate to take on writing a full language parser just to add some new info to the end of a line or the top of a function. It seems like this is almost what is going to be required but it also seems like there should be some tools out there to do these types of manipulations already. The code to be changed is in a variety of languages, but I'm particularly interested in FORTRAN. Any thoughts?

  • What is the most accurate/frequent report on browser usage on the Internet?

    - by Ryan Hayes
    I'm determining which browsers a new site should support. I'm looking for a respected and accurate (as possible) report on the browser versions that are currently in use. This report should, at minimum cover the % of people who use what browsers, and versions of that browser. Is there a widely accepted source for this kind of report? If so, are they regularly released and available for free? Bonus points for other metrics such as breaking down by OS, Flash versions, JS versions, etc.

  • Why do some open source projects do not allow to report issues in a public issue tracker?

    - by linquize
    Why do some open source projects do not allow to report issues in a public issue tracker? Those projects requires the issues to be reported via email, and the issues may be forwarded to people in mailing list. Users may repeatedly report the same issue if there is no public issue tracker, as they have no easy way to know what have been reported before. The project team members need to spend extra time answering those repeated issues. Some projects do have a public issue tracker, but the issues are still reported through email and they are posted only by the project team only after filtering. It does not allow anyone to report directly in issue tracker. (example: SVN) Such arrangement is not transparent nor open, which I think it violates the philosophy of open source. And it is outdated.

  • Programmatically Insert Page Break in Active Report

    - by Kevin Babcock
    I've been scouring the web for a good example, but cannot figure out how to add a page break to an Active Reports report programmatically. The reports I'm working with usually require 1-2 pages for each record. In order to support dual-sided printing of the reports I want to insert a blank page for each record that uses an odd number of pages, ensuring that each new record is printed on the front of each printed page. I'm very new to Active Reports, so any suggestions, code samples, or links are much appreciated!

  • Crystal Reports Xi - Sorting a CrossTab Report by a Summary Field

    - by Albert
    So I have a simple crosstab report that calculates number of sales in the columns, and the rows are each office. The last column on the right is a total column, which contains a summary field (via a count of the identity field) that adds up the total number of sales per office. How can I sort the crosstab data so the office with the most sales is the top row, and the rest in order under it?

  • Visual Studio 2008 Report Designer - can't turn on gridlines

    - by bob
    Microsoft in their infinite wisdom have seen fit to remove the useful "Draw Grid" and "Snap to Grid" checkboxes in the report properties dialog that were in VS 2005 but are not in VS 2008. I'm assuming they put that functionality elsewhere but I can't find it after going through what seems like every menu option available. Does anybody know how to turn on the gridlines?
