  • Help regarding no sql databases like hadoop, hbase etc

    - by user560370
    I am new to the distributed NoSQL databases like Hadoop, Cassandra, etc. I have few questions for which I seek an expert advice: Can you list problems/challenges one will generally face when making a shift from the present conventional database like MySQL to these large cluster-based databases? What are the difficulties, if any, when one needs to adapt to a newer version of these open source projects? Can you list out the things which are generally stored/kept in memcached for fast rendering of the page? How can I understand the source code of open-source projects so that I can build on it and maybe give back to the community? Above questions may sound to be idiotic and basic but please it's a request for the experts to answer the above questions in detailed and to best of their abilities.

  • Using Nokogiri to scrape groupon deal

    - by hyngyn
    I'm following the Nokogiri railscast to write a scraper for Groupon. I keep on getting the following error when I run my rb file. traveldeal_scrape.rb:10: warning: regular expression has ']' without escape: /\[0-9 \.]+/ Flamingo Conference Resort and Spa Deal of the Day | Groupon Napa / Sonoma traveldeal_scrape.rb:9:in `block in <main>': undefined local variable or method `item' for main:Object (NameError) Here is my scrape file. require 'rubygems' require 'nokogiri' require 'open-uri' url = "http://www.groupon.com/deals/ga-flamingo-conferences-resort-spa?c=all&p=0" doc = Nokogiri::HTML(open(url)) puts doc.at_css("title").text doc.css(".deal").each do |deal| title = deal.at_css("#content//a").text price = deal.at_css("#amount").text[/\[0-9\.]+/] puts "#{title} - #{price}" puts deal.at_css(".deal")[:href] end I used the exact same rubular expression as the tutorial. I am also unsure of whether or not my CSS tags are correct. Thanks!

  • Http Hanlder must be reset with each deployment. How can I add this functionality to the web.config

    - by user42942
    My application is a dotnet 4 hybrid - MVC in some areas, web forms in others. This application was recently upgraded to dotnet 4 and includes a lot of older code and some mismatched parts. Unfortunately it includes a telerik component that requires me to run the Application pool in classic mode. In order to fix this (in IIS7) I have to add a handler mapping to the IIS configuration. This mapping is basically a wildcard mapping that points the wildcard path "*" to the %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll. The problem I am running into is this: For some reason this mapping gets dropped when deploying the site. So, can I add the functionality of this mapping to the web config? If so, How? Or is there another solution to make this manually added mapping "sticky" so that it remains in place during and after a deployment? (I am also asking this on StackOverflow, as I'm not sure if this should be a coding question or a Server question)

  • Appending html code to a section inside a dialog window isn't working in IE6

    - by user338413
    I'm using jQuery's validation on a form. When the form is validated, I'm using a submitHandler to fill a dialog with data from the form then I open the dialog to display it. Works great except for in IE6. Nothing displays. I've tried initializing the dialog before and after running the validation code but neither makes a difference. Here's the validation code: $("#acct").validate({ ... submitHandler: function() { fillVerificationDialog(); $("#verification_dialog").dialog('open'); return false; } }); Here's the fillVerificationDialog: function fillVerificationDialog() { $("#dialog-data").empty(); $("<span class='label'>").text("First Name: ").appendTo("#dialog-data"); $("<span class='value'>").text($("#firstname").val()).appendTo("#dialog-data"); $("<br/>").appendTo("#dialog-data"); ... }

  • creating ports and initiating communication between client and server

    - by dave
    what i need is a server that listens to 5060 port , when the client sends data to that port the server should open up another port ( any port after 1250 i believe ) and forward the clients data to that port keeping 5060 idle so it can perform the same function for the next client so basically i need the server to a) open up multiple ports one for each client b) get the voice data from the client and be able to send voice data to that client i m looking into the hardware specs and other such details of the scenario so i dont have time to make such a program myself if theres a code that i can run directly ( both server and client side ) on visual studio .net 2010 that will perform these tasks then that would be extremely helpful thanks alot in advance

  • Combining database tables

    - by zSysop
    Hi all, I have two tables which look kind of similar and i was thinking about combining them and thought i would get some input from everyone. Here's what they currently look like: Issues Id | IssueCategory | IssueType | Status | etc.. ------------------------------------------------- 123 | Copier | Broken | Open | 124 | Hardware | Missing | Open | CopierIssueDetails Id | IssueId | SerialNumber | Make | Model | TonerNumber | LastCount --------------------------------------------------------------------- 1 | 123 | W12134 | Dell | X1234 | 12344555 | 500120 HardwareTicketDetails Id | IssueId | EquipmentNumber | Make | Model | Location | Toner | Monitor | Mouse ----------------------------------------------------------------------------------- 1 | 124 | X1123113 | Dell | XXXX | 1st floor | 0 | 1 | 0 What do you guys think about combining these two tables into one. Would it be a good idea or is it better to keep them separated like this? Thanks in advance for any suggestions.

  • bottle.py on EC2 micro instance causes 2 order of magnitude slowdown

    - by user61633
    Cross-posted from StackOverflow: I wrote a little toy script to solve this type of game, and put it on my new micro EC2 instance. It works perfectly, but while it takes around 0.5 seconds to run a local version, and takes under 0.5 seconds to run both the local and the bottle.py version on my home computer, running the bottle.py version on the EC2 instance takes over 2 minutes. Python has the cpu pegged at 99% the entire time. Only 7.4% memory usage, consistently, and no swapping. The only guess I have is initialization time for bottle.py on EC2, but if it were that, why would it be ~200x faster on my own computer with bottle.py?

  • Is there a way to make this perl code capture stderr as well as stdout from a tcsh?

    - by mikelong
    open UNIT_TESTER, qq(tcsh -c "gpath $dir/$tsttgt; bin/rununittests"|); while(<UNIT_TESTER>){ reportError($ignore{testabort},$tsttgt,"test problem detected for $tsttgt:$_ ") if /core dumped/; reportError($ignore{testabort},$tsttgt,"test problem detected for $tsttgt:$_ ") if /\[ FAILED \]/; writelog($tsttgt,$_); } close UNIT_TESTER; I have tried to redirect stderr to stdout using this syntax but it didn't work: open UNIT_TESTER, qq(tcsh -c "gpath $dir/$tsttgt; bin/rununittests >& "|); I have also read the discussion on the perl FAQ but that was in relation to bash: http://www.perl.com/doc/FAQs/FAQ/oldfaq-html/Q5.15.html

  • Multiple resultsets from Oracle in Odp.net,without refcursors

    - by James L
    SQL Server is able to return the results of multiple queries in a single round-trip, e.g: select a, b, c from y; select d, e, f from z; Oracle doesn't like this syntax. It is possible to use reference cursors, like this: begin open :1 for select count(*) from a; open :2 for select count(*) from b; end; However, you incur a penalty in opening/closing cursors and you can hold database locks for an extended period. What I'd like to do is retrieve the results for these two queries in one shot, using Odp.net. Is it possible?

  • How to copy and paste code with retaining the format

    - by Sab
    This question may have been asked before but I was unable to find any solution. So here goes: When I browse and see some code that I would like to copy I simply use ctrl+c and ctrl+v. Most of the time this works fine. But in some cases (websites like stackoverflow and others ) when I copy the code and paste it , it only comes on one line in eclipse. I have tried pasting this code into eclipse and select all and hitting auto format but this doesnt help either. I have also pasted the code into komodo and word. But to no avail. The code simply refuses to align itself. Does anyone know any solution to this?

  • Ruby string encoding problem

    - by John Prideaux
    I've looked at the other ruby/encoding related posts but haven't been able to figure out why the following is not working. Likely just because I'm dense, but here's the situation. Using Ruby 1.9 on windows. I have a set of CSV files that need some data appended to the end of each line. Whenever I run my script, the appended characters are gibberish. The input text appears to be IBM437 encoding, whereas my string I'm appending starts as US-ASCII. Nothing I've tried with respect to forcing encoding on the input strings or the append string seems to change the resultant output. I'm stumped. The current encoding version is simply the last that I tried. def append_salesperson(txt, salesperson) if txt.length > 2 return txt.chomp.force_encoding('US-ASCII') + %(, "", "", "#{salesperson}") end end salespeople = Hash[ "fname", "Record Manager"] outfile = File.open("ActData.csv", "w:US-ASCII") salespeople.each do | filename, recordManager | infile = File.open("#{filename}.txt") infile.each do |line| outfile.puts append_salesperson(line, recordManager) end infile.close end outfile.close

  • Apache htdocs in folder with unicode name

    - by Zsolti
    I have my apache (for windows) htdocs in a folder like c:\anything1\????\anything2. The problem is that in this case php won't execute any scripts from here and will display an error message like this: `Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'c:/anything1/????/anything2/index.php' (include_path='.;C:\php5\pear') in Unknown on line 0 ` If I try to open a html file, it is served by apache, so it seems that the problem appears only with php. Do you have an idea how to solve this?

  • Dual boot centOS and Win7

    - by user1855965
    I posted this on stackoverflow, but it looks like superuser would be more appropriate. I have a CentOS 5 machine that runs Windows 7 as a dual boot. CentOS is the main OS and each OS is set up in a specific hard drive. This was set up before I joined the company and I don't really have need to run Windows now. My question is: can I, from CentOS, reformat the Windows HD, change GRUB settings and get the HD to be available on CentOS? Happy to provide more info if this helps. Many thanks for your help and apologies if this is a very simple issue... I don't want to blindly test things on this machine as it is used on a daily basis by several users.

  • Are there any platforms where using structure copy on an fd_set (for select() or pselect()) causes p

    - by Jonathan Leffler
    The select() and pselect() system calls modify their arguments (the 'struct fd_set *' arguments), so the input value tells the system which file descriptors to check and the return values tell the programmer which file descriptors are currently usable. If you are going to call them repeatedly for the same set of file descriptors, you need to ensure that you have a fresh copy of the descriptors for each call. The obvious way to do that is to use a structure copy: struct fd_set ref_set_rd; struct fd_set ref_set_wr; struct fd_set ref_set_er; ... ...code to set the reference fd_set_xx values... ... while (!done) { struct fd_set act_set_rd = ref_set_rd; struct fd_set act_set_wr = ref_set_wr; struct fd_set act_set_er = ref_set_er; int bits_set = select(max_fd, &act_set_rd, &act_set_wr, &act_set_er, &timeout); if (bits_set > 0) { ...process the output values of act_set_xx... } } My question: Are there any platforms where it is not safe to do a structure copy of the struct fd_set values as shown? I'm concerned lest there be hidden memory allocation or anything unexpected like that. (There are macros/functions FD_SET(), FD_CLR(), FD_ZERO() and FD_ISSET() to mask the internals from the application.) I can see that MacOS X (Darwin) is safe; other BSD-based systems are likely to be safe, therefore. You can help by documenting other systems that you know are safe in your answers. (I do have minor concerns about how well the struct fd_set would work with more than 8192 open file descriptors - the default maximum number of open files is only 256, but the maximum number is 'unlimited'. Also, since the structures are 1 KB, the copying code is not dreadfully efficient, but then running through a list of file descriptors to recreate the input mask on each cycle is not necessarily efficient either. Maybe you can't do select() when you have that many file descriptors open, though that is when you are most likely to need the functionality.) There's a related SO question - asking about 'poll() vs select()' which addresses a different set of issues from this question.

  • Visual studio 2010 colourizers, intellisense and the rest. Where to start!!

    - by Owen
    Ok, before I begin I realize that there is a lot of documentation on this subject but I have thus far failed to get even basic colourization working for VS2010. My goal is to simply get to a point where I can open a document and everything is coloured red, from here I can implement the relevant parsing logic. Here's what I have tried/found: 1) Downloaded all the relevent SDK's and such- Found the ook sample (http://code.msdn.microsoft.com/ookLanguage) - didn't build, didn't work. 2) Knowing almost nothing about MEF read through "Implementing a Language Service By Using the Managed Package Framework" - http://msdn.microsoft.com/en-us/library/bb166533(v=VS.100).aspx This was pretty much a copy and paste of all the basic stuff here, and also updating some references which were out of date with the sample see: http://social.msdn.microsoft.com/Forums/en-US/vsx/thread/a310fe67-afd2-4592-b295-3fc86fec7996 Now, I have got to a point where when running the package MEF appears to have hooked up correctly (I know this because with the debugger open I can see that the packages initialize and FDoIdle methods are being hit). When I open a file of the extension I have registered with the ProvideLanguageExtensionAttribute everything dies as if in an endless loop, yet no debug symbols hit (though they are loaded). Looking at the ook sample and the MEF examples they seem to be totally different approaches to the same problem. In the ook sample there are notions of Clasifications and Completion controllers which aren't mentioned in the MEF example. Also, they don't seem to create a Package or Language service, so I have no idea how it should work? With the MEF example, my assumption is that I need to hook into the "IScanner.ScanTokenAndProvideInfoAboutIt" to provide syntax highlighting? Which would be fine if I could ever hit this method. So my first question I guess is which approach should I be taking here? Or do they both somehow tie together? My second questions is, where can I find a basic fully working project that implements bog standard basic syntax highlighting and intellisense or VS2010? Thirdly, in the MEF example when I created a Package there were a bunch of test projects created for me. I appears that the integration tests launch the VS2010 test rig somehow, but the test fails. It would be good to write my service with tests but I have no idea what/how I can test each interaction so any references to testing Language services would be helpful. Finally, please throw any resource/book links my way that I may find useful. Cheers, Chris. N.B. Sorry I realize this is part question part rant, but I have never been so confused.

  • the breakpoint will not currently be hit no symbols loaded

    - by Carlos_Liu
    I want to debug on the customer's machine (Windows Server 2003) to track a problem, and out product is based on .NET 2.0. I want to use DbgCLR.exe to debug a file AAA.dll, what I did is: install .NET 2.0 SDK on the customer's machine (to get the DbgCLR.exe) copy the symbol file AAA.pdb to the same directory with AAA.dll get the source file for AAA.dll the AAA.dll will be loaded by w3wp.exe, so in the DbgCLR Tools-Attach to Process, then I choose w3wp.exe File-Open-File open the source file and add a breakpoint in the function which will be callled but the breakpoint seems do no work because there is an warning icon on it and says : the breakpoint will not currently be hit. No symbols have been loaded for this document. On my computer (Windows XP) which has the debug version of whole source code, I did nearly the same thing as above but the different is: I attached aspnet_wp.exe to do the debug and it works What should I do to let it work on the customer's machine?

  • Error connecting to the application.

    - by ahmed
    Hi guys, let me explain you the current scenario. We have a asp.net application on framework 2 running on intranet(Windows 2003 Server and Sql Server 2000). Now we have a xp machine where we installed and configured IIS with a virtual directory pointing on the local Xp machine and this machine is connected to our intranet. We have copied the same application files of the server to this XP machine. But the thing is the connection string/database of the application is pointing towards the intranet server. The problem is when we try to run the application on the XP machine we get this error : An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) Is this query related or concerned with this site or stackoverflow ?

  • Excel 2010: How to color the area between charts?

    - by Quasdunk
    Hello, I asked this question already on stackoverflow but it hasn't been answered yet. Instead I was advised to try it here, so here I go :) So there's that simple XY-Line-Chart in Excel (2010). It is surrounded by two other graphs which are parallel but offset by the same factor in both the positive and negative direction - something like this: ---------------- (positively offset parallel graph) ---------------- (main graph) ---------------- (negatively offset parallel graph) Now I want to color the space between the main graph and the offset ones, but I just can't seem to find a way! Is it maybe possible with VBA? Or is there maybe a solution for Excel 2007?
