  • .NET Deployment Framework

    - by Khash
    Many people use Nant or Powershell for deployment of their apps to different servers/environments. These are based on scripting while some solutions allow deployment to be embedded in code like Migrator.Net and other Ruby inspired Db deployment/migration frameworks in .NET. I was wondering if there are any frameworks for .NET for application deployment that would allow developers to embed full deployment inside code. Things like copying files, creating web apps in IIS, stopping and starting services and so on.

  • What freeware/floss tools are available to help load data into SPSS?

    - by tardate
    I'm looking for a solution for producing SPSS format data files for loading into SPSS. The few offerings I can find are all commercial. Has anyone experience with generating SPSS-format data files using open-source, freeware or home-grown solutions? I'm not even sure that the file format is "open". Any hints appreciated (any language is fine, although java, perl or ruby preferred).

  • Problem with GetDefaultPrinter() over a VPN c++

    - by Ian Crowder
    I am writing an application that gets its dimensions from the paper ratio of the default printer of the local computer. This all works well unless the default printer is over a VPN. When this is the case, calling GetDefaultPrinter() takes too long. I need to find a way to put a time constraint on GetDefaultPrinter() and if it exceeds that constraint, break out of the function. Any possible solutions would be great. Thanks, Ian

  • java max heap size, how much is too much

    - by brad
    I'm having issues with a JRuby (rails) app running in tomcat. Occasionally page requests can take up to a minute to return (even though the rails logs processed the request in seconds so it's obviously a tomcat issue). I'm wondering what settings are optimal for the java heap size. I know there's no definitive answer, but I thought maybe someone could comment on my setup. I'm on a small EC2 instance which has 1.7g ram. I have the following JAVA_OPTS: -Xmx1536m -Xms256m -XX:MaxPermSize=256m -XX:+CMSClassUnloadingEnabled My first thought is that Xmx is too high. If I only have 1.7gb and I allocated 1.5gb to java, i feel like I'll get a lot of paging. Typically my java process shows (in top) 1.1g res memory and 2g virtual. I also read somewhere that setting the Xms and Xmx to the same size will help as it eliminates time spend on memory allocation. I'm not a java person but I've been tasked with figuring out this problem and I'm trying to find out where to start. Any tips are greatly appreciated!! update I've started analyzing the garbage collection dumps using -XX:+PrintGCDetails When i notice these occasional long load times, the gc logs go nuts. the last one I did (which took 25s to complete) I had gc log lines such as: 1720.267: [GC 1720.267: [DefNew: 27712K->16K(31104K), 0.0068020 secs] 281792K->254096K(444112K), 0.0069440 secs] 1720.294: [GC 1720.294: [DefNew: 27728K->0K(31104K), 0.0343340 secs] 281808K->254080K(444112K), 0.0344910 secs] about 300 of them on a single request!!! Now, I don't totally understand why it's always GC'ng from ~28m down to 0 over and over.

  • Code Golf: Evaluating Mathematical Expressions

    - by Noldorin
    Challenge Here is the challenge (of my own invention, though I wouldn't be surprised if it has previously appeared elsewhere on the web). Write a function that takes a single argument that is a string representation of a simple mathematical expression and evaluates it as a floating point value. A "simple expression" may include any of the following: positive or negative decimal numbers, +, -, *, /, (, ). Expressions use (normal) infix notation. Operators should be evaluated in the order they appear, i.e. not as in BODMAS, though brackets should be correctly observed, of course. The function should return the correct result for any possible expression of this form. However, the function does not have to handle malformed expressions (i.e. ones with bad syntax). Examples of expressions: 1 + 3 / -8 = -0.5 (No BODMAS) 2*3*4*5+99 = 219 4 * (9 - 4) / (2 * 6 - 2) + 8 = 10 1 + ((123 * 3 - 69) / 100) = 4 2.45/8.5*9.27+(5*0.0023) = 2.68... Rules I anticipate some form of "cheating"/craftiness here, so please let me forewarn against it! By cheating, I refer to the use of the eval or equivalent function in dynamic languages such as JavaScript or PHP, or equally compiling and executing code on the fly. (I think my specification of "no BODMAS" has pretty much guaranteed this however.) Apart from that, there are no restrictions. I anticipate a few Regex solutions here, but it would be nice to see more than just that. Now, I'm mainly interested in a C#/.NET solution here, but any other language would be perfectly acceptable too (in particular, F# and Python for the functional/mixed approaches). I haven't yet decided whether I'm going to accept the shortest or most ingenious solution (at least for the language) as the answer, but I would welcome any form of solution in any language, except what I've just prohibited above! My Solution I've now posted my C# solution here (403 chars). Update: My new solution has beaten the old one significantly at 294 chars, with the help of a bit of lovely regex! I suspected that this will get easily beaten by some of the languages out there with lighter syntax (particularly the funcional/dynamic ones), and have been proved right, but I'd be curious if someone could beat this in C# still. Update I've seen some very crafty solutions already. Thanks to everyone who has posted one. Although I haven't tested any of them yet, I'm going to trust people and assume they at least work with all of the given examples. Just for the note, re-entrancy (i.e. thread-safety) is not a requirement for the function, though it is a bonus. Format Please post all answers in the following format for the purpose of easy comparison: Language Number of characters: ??? Fully obfuscated function: (code here) Clear/semi-obfuscated function: (code here) Any notes on the algorithm/clever shortcuts it takes.

  • CFHTTP and IIS 7 Connection Failture (NOT SSL)

    - by Dave Quested
    I'm trying to do a very simple CFHTTP GET call to a local website running on IIS7, however it throws a 408 Connection Failure. I've done all the obvious things: The site is listed in the hosts file locally I've added the CFHTTPPARAM tags for IIS compression issues (deflate;q=0) Surfing to the URL in the browser works fine Doing a CFHTTP to google.com works fine, no local sites work at all. When searching on Google there are others that have had this, but no solutions. Anyone successfully got through this issue?

  • iGoogle Stack Overflow Gadget [closed]

    - by Charango
    Since SO's question database is becoming an excellent first point of call for finding answers to coding problems, some people (like me) might like to be able to fire up searches from their iGoogle home page, among the other searches you might launch from there. I've created a very simple gadget to do this, and put the source below. My hope is that this might provide a foundation on which community members with better ideas for performing this function, or ideas for enhancing it, can update it. Perhaps we could make it configurable to search via a site scope search from Google and / or a question search, for instance. I've hosted and registered this first version but if anyone makes changes and can host a new version / new pics elsewhere, please feel free. <?xml version="1.0" encoding="UTF-8"?> <Module> <ModulePrefs title="Stack Overflow Search" author="Community Wiki" author_email="[email protected]" author_affiliation="Stack Overflow" author_location="The Internet" author_aboutme="All sorts" author_link="http://stackoverflow.com" author_quote="Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law." description="Stack Overflow is rapidly becoming one of the best resources for finding answers to your programming questions.

  • How can i display a MFC CHtmlView inside a dialog?

    - by Lothar
    I found a lot of links on the internet for this question but i don't understand their (partial) solutions. One of the main problems seems that i'm builing all dialogs by hand without dialog resource files or the Visual Studio Application Wizards. So i would need pure C++ code that i can type into my Editor. There is also some reference to a "CWebBrowser2" control, but a grep on the VC directory does not give me any results, so where can i find this?

  • Tomcat deployment overwrites context.xml

    - by Kristoffer
    Hi, I'm pretty new to Tomcat in general, so please point out if got anything wrong. My question is regarding updates to already deployed apps, using the Tomcat manager. But first thing first. I'm using the META-INF/Context.xml for storing connection info for the database connections, so this is unique to every server the application is deployed to. I'm not sure if this is optimal but it's the only way I know. So, when updating the application, it's important that this file doesn't get modified, because I don't want to have to go in and remake all changes every time I update my app. For updating, I'm using the Tomcat Manager, and I've tried different approaches but everything seems to build on the process of undeploy, then deploy the new version. This way, the Context.xml gets removed/replaced by an empty Context.xml file. So my question is basically, how do I update a running webapp, and at the same time having the Context.xml left untouched? Btw, I'm running Tomcat 6.0.24.

  • minimal rsync installation on windows xp?

    - by Aman Jain
    Hi I want to install rsync on windows xp. I have searched the web, but most of the solutions suggest using cygwin, but is there any other way to do this? I don't want to install cygwin because it takes lot of space. Moreover, I need to make it communicate with a rsync daemon on Linux, therefore alternatives to rsync on windows won't help. Thanks

  • Next generation of command shells?

    - by ignatius
    I am curious about if there is any project about a replacement for the current unix-shells (like bash, ash, rsh ...), at least adding some new ideas or paradigm in this area. I was searching but i found very few information, this project http://en.wikipedia.org/wiki/Friendly_interactive_shell seems interesting, but not so diferent from the nowadays solutions. What do you think? Do you imagine a linux-distribution on 2020 that still having bash? How can be an evolution of this programs? Br

  • Changing Opacity of All Elements but One Div

    - by waiwai933
    I'm trying to fade all elements on a webpage except for one div. I've been able to fade all the elements with the following jQuery: $('*').css('opacity', .3); However, it seems as if opacity is a property that inherits from parent elements, even if I explicitly set the opacity of the div to 1. I'm drawing a blank as to any solutions right now, so can I have some help here?

  • Ubuntu 13.04 to 13.10: Filesystem check or mount failed [migrated]

    - by SamHuckaby
    I attempted to upgrade from Ubuntu 13.04 to 13.10 today, and mid upgrade the system started flaking out, and eventually locked up entirely. I was forced to restart the computer, and am now unable to get the computer to boot up at all. When I boot currently, it takes me to the GRUB menu, and I can choose to boot normally, or boot in an older version. I have tried several things, which I list below, but no matter what, when I try to finish booting into Ubuntu, I receive the following error: Filesystem check or mount failed. A maintenance shell will now be started. CONTROL-D will terminate this shell and continue booting after re-trying filesystems. Any further errors will be ignored root@ubuntu-computername:~# I have fun fsck -f and everything appears correct, no errors are reported. and it passes all 5 checks. If I run fdisk -l then I get the following information: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 4096 bytes / 4096 bytes Disk identifier: 0x00010824 Device Boot Start End Blocks Id System /dev/sda1 * 2048 608456703 304227328 83 Linux /dev/sda2 608458750 625141759 8341505 5 Extended Partition 2 does not start on physical sector boundary. /dev/sda5 608458752 625141759 8341504 82 Linux swap / Solaris Disk /dev/sdb: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0fb4b7e8 Device Boot Start End Blocks Id System /dev/sdb1 8192 625139711 312565760 7 HPFS/NTFS/exFAT I am considering just installing a new OS on the other disk, that currently has nothing on it, and then just attempting to scrape my data off the old disk (thankfully I didn't encrypt the files). Really my question is this: Can I salvage this Ubuntu install, or should I give up and just reinstall?
