  • Android: how to share code between projects signed with the same certificate

    - by tomash
    In Android documentation concerning code signing we can read: "By signing multiple applications with the same certificate and using signature-based permissions checks, your applications can share code and data in a secure manner." How exactly such code sharing can be done? Is it possible to release main application and multiple exchangeable plugins then discover them at runtime? What does source code looks like and what are advantages over "standard" intents calls from/to different APK packages?

  • Addresses stored in SQL server have many small variations(errors)

    - by MAW74656
    I have a table in my database which stores packing slips and their information. I'm trying to query that table and get each unique address. I've come close, but I still have many near misses and I'm looking for a way to exclude these near duplicates from my select. Sample Data CompanyCode CompanyName Addr1 City State Zip 10033 UNITED DIE CUTTING & FINISHIN 3610 HAMILTON AVE CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE. CLEVELAND Ohio 44114 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVENUE CLEVELAND Ohio 44114 10033 UNITED DIECUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44144 10033 UNITED FINISHING 3610 HAMILTON AVE CLEVLAND Ohio 44114 10033 UNITED FINISHING & DIE CUTTING 3610 HAMILTON AVE CLEVELAND Ohio 44114 And all I want is 1 record. Is there some way I can get the "Average" record? Meaning, if most of the records say CLEVELAND instead of CLEVLAND, I want my 1 record to say CLEVELAND. Is there any way to par this data down to what I'm looking for? Desired Output CompanyCode CompanyName Addr1 City State Zip 10033 UNITED DIE CUTTING & FINISHING 3610 HAMILTON AVE CLEVELAND Ohio 44114

  • Python: slow read & write for millions of small files

    - by Jami
    I am building directory tree which has tons of subdirectories and files. The total directory count is somewhere along 256^32 subdirectories with 256 files in each end which are only a few bytes long. I did this so I would have fast access to these files (since i'm not searching and i'm just directly accessing then via a known file path) I have a python script that builds this filesystem and reads & writes those files. The problem is that when I reach more than 1Gb of total filesize, the read and write methods become extremely slow. Here's the function I have that reads the contents of a file (the file contains an integer string), adds a certain number to it, then writes it back to the original file. def addInFile(path, scoreToAdd): num = scoreToAdd try: shutil.copyfile(path, '/tmp/tmp.txt') fp = open('/tmp/tmp.txt', 'r') num += int(fp.readlines()[0]) fp.close() except: pass fp = open('/tmp/tmp.txt', 'w') fp.write(str(num)) fp.close() shutil.copyfile('/tmp/tmp.txt', path) I previously tried performing linux console commands but it was slower. I copy the file to a temporary file first then access/modify it then copy it back because i found this was faster than directly accessing the file. I think the cause of the slowdown is because there're tons of files. performing this function 1000 times sometimes reach 1 minute now, but before (when there were only a few files, 1000 calls was performed for only less than 1 second) How do you suggest I fix this?

  • Learning Spring MVC For web-projects

    - by John
    I have looked at Spring MVC a few times briefly, and got the basic ideas. However whenever I look closely it seems to require you already know a whole load of 'core Spring'. The book I have for instance has a few hundred pages before it gets onto Spring MVC... which seems a lot to wade through. I'm used to being able to jump in, but there's so much bean-related stuff and XML, it just looks like a mass of data to consume. Does it simplify if you put the time in, or is Spring just a much bigger framework than I thought? is it possible to learn this side of it in isolation?

  • Localized License Agreements in Visual Studio Setup Projects?

    - by byanity
    I've added a EULA using VS2005's built in License Agreement UI form in a Setup Project. This form has a LicenseFile property that you set to an RTF file that displays the EULA. Assuming I have a number of translated RTFs, how can I make the EULA that is displayed point to the appropriate RTF localized to the user's Windows CurrentCulture settings? I've seen some articles on WiX but at this point I need to stick with our current installation setup. Thanks!

  • Using svn with xampp for php projects

    - by idrish
    I have heard a lot about version control and would like to work on it. I read some tutorials about the same. However i am not quite sure how svn works with xampp. I have installed svn, Tortoise svn and made the necessary changes in xampp. For instance i copied the two required modules to c:/xampp/apache/modules and also made changes to the conf file in apache. Here are the changes made in c:/xampp/apache/conf/httpd.conf. # Configure Subversion repository <Location /svn> DAV svn SVNPath “C:\svn” AuthType Basic AuthName “Subversion repository” AuthUserFile “c:\svn_conf\passwd” Require valid-user </Location>t I created the repository at c:/svn and also created the password file. However when i visit http:/localhost/svn i get a 404 page not found error. Where am i going wrong. what am i missing.? Any pointers?? Thanks in advance.

  • Good language to learn in order to build small websites

    - by mkoryak
    I want to start building websites and charging people for them! My problem is that the stack that know well does not lend itself to quick development, or cheap hosting. I am looking for languages that satisfy the following criteria: Fast to develop in Can find cheap hosting for it Bonus points if it can also be 'enterprisey'

  • tcpdf - HTML table showing up way too small

    - by LinuxGnut
    Hi folks. I'm using tcpdf (http://www.tcpdf.org/) to generate PDFs of some tables and images. The images are loaded without an issue, but I'm having issues with the writeHTML() function. I can't seem to control the font sizes or table width/height through the HTML, so I end up with a tiny, tiny, tiny table that you have to print of and squint at to even attempt reading. I've tried editing the table itself, CSS, even putting the table itself inside an h1, but nothing is changing the font size. I have the font size in tcpdf set to 16, but this also has no affect. Has anyone else run into this issue?

  • Standard Practice for Continuous Integration of Maven Multi-module projects

    - by James Kingsbery
    I checked around, and couldn't find a good answer to this: We have a multi-module Maven project which we want to continuously integrate. We thought of two strategies for handling this: Have our continuous integration server (TeamCity, in this case, but I've used others before and they seem to have the same issue) point to the aggregator POM file, and just build everything Have our continuous integration server point at each individual module Is there a standard, preferred practice for this? I've checked Stack Overflow, Google, the Continuous Integration book, and did not find anything, but maybe I missed it.

  • Pure-JavaScript projects in NetBeans?

    - by Matt Zukowski
    This seems like it ought to be obvious, yet I can't figure it out. I do a lot of JavaScript coding, and I really like NetBeans. Unfortunately I can't figure out how to create a "JavaScript" project in NetBeans. If I go to File - New Project, my only options are "Java", "Ruby", and "NetBeans Modules". I don't want any of these. My project consists mostly of JavaScript, with a little bit of CSS. I ususally just end up creating a "Ruby" project, but this seems retarded, since I don't actually have any Ruby code. Why isn't there an option to create a "JavaScript" or "Web" project, or at least a "Generic" project that doesn't revolve around a specific language? Am I missing something here?

  • Asp.net mvc small amount data storage

    - by Trimack
    Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

  • Supporting more than one codebase in ANSI-C

    - by Ilker Murat Karakas
    I am working on a project, with an associated Ansi-C code base. (let me call this the 'main' codebase). I now am confronted with a typical problem (stated below), which I believe I would be able to solve much easily if I had an object-oriented language at hand. The problem is this: I will have to start more than one codebases; i.e. I will have to start supporting a parallel codebase (even maybe more in the future). The initial codebases for all the new (i.e. parallel) codebases will initially be identical as the old (i.e. 'main') codebase. As we are talking about the 'C' language, I have till now been thinking of adding '#ifdef' statements to code, and writing the branch-spacific code inside those 'ifdef' blocks. Hoping that I made the problem clear (enough!), I would like to hear thoughts on clever patterns that would help me handle this problem elegantly in Ansi C. Cheers

  • Delphi Pascal / Windows API - Small problem with SetFilePointerEx and parameter FILE_END

    - by SuicideClutchX2
    I know I am about to be slapped by at least one person who was helping me with this API. Alright I have been able to use SetFilePointerEx just fine, when setting the position only. SetFilePointerEx(PD,512,@PositionVar,FILE_BEGIN); SetFilePointerEx(PD,0,@PositionVar,FILE_CURRENT); Both work, I can set positions and even check my current one. But when I set FILE_END as per the documentation no matter what the second parameter is and whether or not i provide a pointer for the third parameter it fails even on a valid handle that many other operations are able to use without fail. For Example: SetFailed := SetFilePointerEx(PD,0,@PositionVar,FILE_END); SetFailed := SetFilePointerEx(PD,0,nil,FILE_END); Whatever I put it fails. I am working with a handle to a physical disk and it most definitely has an end. SetFilePointer works just fine its just a little more trouble than I would like. Its not the end of the world, but whats happening.

  • Are there any MVP Frameworks projects out there?

    - by Greg Malcolm
    MVC is used a number of popular frameworks. To name just a few, Ruby on Rails, ASP.NET MVC, Monorail, Spring MVC. Are there any equivalent frameworks using any variant of MVP? Most of the examples I've found online seem to be custom implementations of the pattern rather than reusable frameworks. Suggestions need not be specific to any particular programming language, my interest is mostly academic.

  • small code redundancy within while-loops (doesn't feel clean)

    - by wallacoloo
    So, in Python (though I think it can be applied to many languages), I find myself with something like this quite often: the_input = raw_input("what to print?\n") while the_input != "quit": print the_input the_input = raw_input("what to print?\n") Maybe I'm being too picky, but I don't like how the line the_input = raw_input("what to print?\n") has to get repeated. It decreases maintainability and organization. But I don't see any workarounds for avoiding the duplicate code without further decreasing the problem. In some languages, I could write something like this: while ((the_input=raw_input("what to print?\n")) != "quit") { print the_input } This is definitely not Pythonic, and Python doesn't even allow for assignment within loop conditions AFAIK. This valid code fixes the redundancy, while 1: the_input = raw_input("what to print?\n") if the_input == "quit": break print the_input But doesn't feel quite right either. The while 1 implies that this loop will run forever; I'm using a loop, but giving it a fake condition and putting the real one inside it. Am I being too picky? Is there a better way to do this? Perhaps there's some language construct designed for this that I don't know of?

  • Small Python optional arguments question

    - by ooboo
    I have two functions: def f(a,b,c=g(b)): blabla def g(n): blabla c is an optional argument in function f. If the user does not specify its value, the program should compute g(b) and that would be the value of c. But the code does not compile - it says name 'b' is not defined. How to fix that? Someone suggested: def g(b): blabla def f(a,b,c=None): if c is None: c = g(b) blabla But this doesn't work, because maybe the user intended c to be None and then c will have another value.

  • Image processing on bifurcation diagram to get small eps size

    - by yCalleecharan
    Hello, I'm producing bifurcation diagrams (which are normally used in nonlinear dynamics). These diagrams identify abrupt changes in topologies due to stability changes. These abrupt changes occur as one or more parameters pass through some critical value(s). An example is here: http://en.wikipedia.org/wiki/File:LogisticMap_BifurcationDiagram.png On the above figure, some image processing has been done so as to make the plot more visually pleasant. A bifurcation diagram usually contains hundreds of thousands of points and the resulting eps file can become very big. Journal submission in the LaTeX format require that figures are to be submitted in the eps format. In my case one of such figures can result in about 6 MB in Matlab and even much more in Gnuplot. For the example in the above figure, 100,000 x values are calculated for each r and one can imagine that the resulting eps file would be huge. The site however explains some image processing that makes the plot more visually pleasing. Can anyone explain to me stepwise how go about? I can't understand the explanation provided in the "summary" section. Will the resulting image processing also reduce the figure size? Furthermore, any tips on reducing the file size of such a huge eps figure? Thanks a lot...

  • One big executable or many small DLL's?

    - by Patrick
    Over the years my application has grown from 1MB to 25MB and I expect it to grow further to 40, 50 MB. I don't use DLL's, but put everything in this one big executable. Having one big executable has certain advantages: Installing my application at the customer is really: copy and run. Upgrades can be easily zipped and sent to the customer There is no risk of having conflicting DLL's (where the customer has version X of the EXE, but version Y of the DLL) The big disadvantage of the big EXE is that linking times seem to grow exponentially. Additional problem is that a part of the code (let's say about 40%) is shared with another application. Again, the advantages are that: There is no risk on having a mix of incorrect DLL versions Every developer can make changes on the common code which speeds up developments. But again, this has a serious impact on compilation times (everyone compiles the common code again on his PC) and on linking times. The question http://stackoverflow.com/questions/2387908/grouping-dlls-for-use-in-executable mentions the possibility of mixing DLL's in one executable, but it looks like this still requires you to link all functions manually in your application (using LoadLibrary, GetProcAddress, ...). What is your opinion on executable sizes, the use of DLL's and the best 'balance' between easy deployment and easy/fast development?

  • Sharing user controls acrros multiple websites

    - by Jasper
    Hello, I am currently working on a project which involves three different websites with a lot of common functionality. At the moment the common functionality is placed in a different website full of user controls. The problem is sharing the user controls across the multiple websites. Looking around on SO and other websites, the only solution seems the be using virtual directories. As this is a workable solution (we us this at the moment) it doesn't seem as a "clean" solution. Which "best practices" exist on sharing common functionality (including the GUI/HTML) between different site? Is it (for example) possible to create a single Web Application project and deploy subdirectories (each with their own web.config) to different production environments?
