  • Coding in Other (Spoken) Languages

    - by contagious
    Something i've always wondered, and I can't find any mention of it anywhere online. When a shop from, say Japan, writes code, would I be able to read it in english? Or do languages, like C, php, anything, have Japanese translations that they write? I guess what i'm asking is does every single coder in the world know enough english to use the exact same reserved words I do? Would this code: If (i < size){ switch case 1: print "hi there" default: print "no, thank you" } else { print "yes, thank you" } display the exact same as I'm seeing it right now in english, or would some other non-english-speaking person see the words "if", "switch", "case", "default", "print", and "else" in their native language? EDIT - yes, this is serious. I didn't know if different localiztions of a language have different keywords. or if there are even different localizations at all.

  • Carrier Wave not completing upload to Rackspace Cloud Files

    - by Zack Fernandes
    Hello, I have been attempting to get file uploads to Rackspace Cloud Files online all night, and finally tried the Carrierwave Plugin. Although the plugin worked right away, when I tried viewing the file uploaded (an image) it was broken. Upon further testing, I found out that files would upload to Cloud Files, however were just a fraction of their original size. I can't seem to figure out what's worng, and any help would be greatly appreciated. My code is as follows. models\attachment.rb class Attachment < ActiveRecord::Base attr_accessible :title, :user_id, :file, :remote_file_url, :file_cache, :remove_file belongs_to :user mount_uploader :file, AttachmentUploader end uploaders\attachment_uploader.rb class AttachmentUploader < CarrierWave::Uploader::Base storage :cloud_files def store_dir "#{model.user_id}-#{model.id}" end end

  • Configuring log4net appenders via XML file *and* code

    - by Dave
    I started to play with log4net today and so far, I really like it. In order to preserve our current logging functionality, the app needs to create a new log file whenever the application is started. The log file name has the date and time stamp encoded in it. Currently, I've got log4net configured via an XmlConfigurator, which works great, except that the filename for my RollingFileAppender is hardcoded in the configuration XML file. I'd like to continue to use the XmlConfigurator, but after calling Configure(), I want to get at the RollingFileAppender and, in code, change its file value to be a dynamically-generated string. The sample documentation online seems to be down right now, but I've poked through the SDK reference, and it looks like I could use the Heirarchy and GetAppenders() to do what I need to do. Am I on the right track?

  • Infix to Postfix and unary/binary operators

    - by Jaapjan
    I have a piece of code that converts an infix expression to an expression tree in memory. This works just fine. There's just one small trouble. I just connect work out how to involve the unary operators correctly (the right associative ones). With the following infix expression : +1 + +2 - -3 - -4 I would expect an RPN of: 1+2++3-4-- Yet, none of the online infix-post converters I can find handle this example in the way I would expect. Does anyone have a clear explanation of handling right associative operators, specifically the binary ones that can be mistaken for the unary ones?

  • Convert perl one-liner into a script

    - by Stefan Lasiewski
    I find alot of perl one-liners online. Sometimes I want to convert these one-liners into a script, because otherwise I'll forget the syntax of the one-liner. For example, I'm using the following command (from nagios.com): tail -f /var/log/nagios/nagios.log | perl -pe 's/(\d+)/localtime/e' I'd to replace it with something like this: tail -f /var/log/nagios/nagios.log | ~/bin/nagiostime.pl However, I can't figure out the best way to quickly throw this stuff into a script. Does anyone have a quick way to throw these one-liners into a Bash or Perl script?

  • Creating a directory in linux assembly language

    - by Jayson Kane
    I am trying to create a small assembly program to create a folder. I looked up the system call for creating a directory on this page: http://www.ctyme.com/intr/rb-8144.htm It says that it is identified by 27h. How would I go about implementing the "mkdir somename" in assembly? I am aware that the program should move 27 into eax but I am unsure where to go next. I have googled quite a bit and no one seems to have posted anthing about this online. This is my current code (I don't know in which register to put filename and so on) section .data section .text global _start mov eax, 27 mov ???????? .... int 80h Thanks

  • PHP client for asmx service

    - by Carlos Mora
    A few days ago I was in charge of the development of some webServices for a client, the thing is that the client also asked for a php client that consumes the webservices. The service were published online on a server, with public access, right now I can see the wsdl from any computer, but when trying to consume it with PHP it shows me an error that says something about HTTP header and blablabla, that happened before I connected with a VPN to the server where the service is being hosted, after doing the VPN just by curiosity I reloaded the php client, and I don't know why... It did worked.... Q: Can anybody tell me why did this happened?

  • How do you implement file drag-and-drop upload in Google Chrome?

    - by Chris R
    I've found several tutorials online about implementing file drag/drop with Firefox 3.6 (they involve using a FileReader object to get the file binary data). However, I cannot create a FileReader object in Chrome on Windows or Mac. Does anyone know what the API is to read and manipulate data from a drag-and-dropped file in Chrome? If I can get the binary data of the file, I already have the rest of the code to perform the upload. Note: I've also tried using the getAsBinary() function call on the file object of the drag event (event.dataTransfer.file) but I believe that is a Mozilla-specific function and not implemented in Chrome. Also, I'm not interested in a solution using google gears or one that requires a user to select files from a dialog. I'm specifically trying to implement a drag-and-drop file upload.

  • How to prepare for a Java test?

    - by Zenzen
    Ok so in two days I have a test for my dream job (well it's an internship, but still!) and for quite some time now I've been reading the SCJP Guide book in order to prepare myself. BUT seeing how slow my reading speed is I guess finding a website with some "java essentials" or "standard java test questions" and going through it in those 2 days would be a better idea. Don't misunderstand me, I do have java experience and it's "only" an internship, but we all know how programming tests look like and how tricky they can be. So are there any online resources you could recommend me? I know 2 days is not much, but well I was informed bout the test 1-2days ago.

  • multiple login pages in ASP.NET forms authentication

    - by Brad
    My bank's website has 2 login pages for online banking. On the first page, I enter my username. If I don't enter a valid username, I get an error message, and do not get to the 2nd page. The 2nd page displays a picture based on my user name, and has me enter my password. If I manually type a URL to a page inside the site after entering my username but before entering my password, I am redirected back to the first login page. Is there a good way to implement this in ASP.NET with Forms Authentication? I only get 1 loginUrl in my web.config. I am fairly certain my bank uses Java.

  • How can I skip the current item and the next in a Python loop?

    - by uberjumper
    This might be a really dumb question, however I've looked around online, etc. And have not seen a solid answer. Is there a simple way to do something like this? lines = open('something.txt', 'r').readlines() for line in lines: if line == '!': # force iteration forward twice line.next().next() <etc> It's easy to do in C++; just increment the iterator an extra time. Is there an easy way to do that in Python? I would just like to point, out the main purpose of this question is not about "reading files and such" and skipping things. I was more looking for C++ iterator style iteration. Also the new title is kinda dumb, and i dont really think it reflects the nature of my question.

    - by Stephen Murby
    Hi, I am looking to be able to pull a list of current OU's from Active Directory I have been looking at some example code online for sometime, but O don't seem to be able to get this to work. string defaultNamingContext; DirectoryEntry rootDSE = new DirectoryEntry("LDAP://RootDSE"); defaultNamingContext = rootDSE.Properties["defaultNamingContext"].Value.ToString(); DirectorySearcher ouSearch = new DirectorySearcher(rootDSE, "(objectClass=organizationalUnit)", null, SearchScope.Subtree); MessageBox.Show(rootDSE.ToString()); try { SearchResultCollection collectedResult = ouSearch.FindAll(); foreach (SearchResult temp in collectedResult) { comboBox1.Items.Add(temp.Properties["name"][0]); DirectoryEntry ou = temp.GetDirectoryEntry(); } The error I get is There provider does not support searching and cannot search LDAP://RootDSE Any Ideas? for each of those returned search results I want to add them to a combo box. (shouldn't be too hard)

  • Parsing JPEG file format: Format of entropy-coded segment (ECS) segments?

    - by me2
    I'm having difficulty understanding the ITU-T T.81 spec for the JPEG file format. Hopefully someone else here has tried to parse JPEG files and/or knows about the details of this file format. The spec indiates that the ECS0 segment starts after the SOS segment but I can't find where in the spec it actually talks about the format of the ECS0 segment or how do detect its start. Simple JPEG implementations online are of limited help because they assume many things about the JPEGs they parse. Can anyone point me in the right direction?

  • UVa #112 Tree Summing

    - by unclerojelio
    I'm working on UVa #112 Tree Summing. I have what I think should be a working solution but it is not accepted by the online judge due to a basic misunderstanding of the problem on my part. Consider the following inputs: -1 (-1()()) 77 (77(1()())()) or diagrammatically, the trees look like: -1 77 / \ / \ () () 1 () / \ () () According to at least two working solutions, the correct output for the above inputs is: yes no However, I don't understand why the second one should be 'no'. It looks to me like the rightmost path of the tree should give the proper sum. What am I missing?

  • Deploying web service

    - by baron
    I am trying to build a webservice that manipulates http requests POST and GET. Here is a sample: public class CodebookHttpHandler: IHttpHandler { public void ProcessRequest(HttpContext context) { if (context.Request.HttpMethod == "POST") { //DoHttpPostLogic(); } else if (context.Request.HttpMethod == "GET") { //DoHttpGetLogic(); } } ... public void DoHttpPostLogic() { ... } public void DoHttpGetLogic() { ... } I need to deploy this but I am struggling how to start. Most online references show making a website, but really, all I want to do is respond when an HttpPost is sent. I don't know what to put in the website, just want that code to run. Some links i've tried so far: http://my.execpc.com/~gopalan/dotnet/webservices/webservice_server.html http://www.beansoftware.com/asp.net-tutorials/deploy-asp.net.aspx http://msdn.microsoft.com/en-us/library/6x71sze4%28VS.80%29.aspx http://www.c-sharpcorner.com/UploadFile/rajaduraip/SimplestwaytoCreateNDeployWebServices12232005054219AM/SimplestwaytoCreateNDeployWebServices.aspx

  • Is there any project estimation tool to give estimate for web design/ development work?

    - by jitendra
    Is there any project estimation tool which gives estimates for web design/ development work? I don't have to calculate Price just want to calculate estimated time. Just for example, for things like: Page creation (layout in XHTML) CSS creation Content creation (Word to HTML, including images in some pages) Bulk PDF upload PHP Script for Form Testing all pages I need like Items Quantity Time for each task(min) Estimated total (in hour) PDF upload x 30 = 2 min = 60 Min pages with images x 30 = 15 min for each = 60 Min Is there any simple JQuery calculator power with JQuery? Where we can add add/remove custom thing to calculate time? Or any other free online/offline tool ?

  • C++ Ambiguous call to Overloaded Function (const variety)

    - by Joe
    After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

    I'm trying to get YouTube feeds with the python gdata library.

  • Alternative to google map api, so that I can use it on a HTTPS/SSL encrypted website.

    - by Zeeshan Rang
    I have a question regarding map api. I was using the the google map api in my website before. But since I have encryption the site using HTTPS/SSL support, the google map api stopped working. I checked online, and realised that google has a Premier account only that would allow me to use HTTPS supported maps api and it cost $10,000 per year. I do not this kind of money with me. So, can you give any other alternative to have a map api on my website. Anything that could give me driving directions would be fine. Regards Zeeshan

  • Is wordpress a good platform for webapp development?

    - by darlinton
    I am planning a webapp to control bank paying orders. In a quick review, the user goes online and creates a payment order. This order goes to other people that pays it and register the payment on the system. The system keeps track of all the payments, keeping the account balance up-to-date. The system needs a login system, bank integration, and to support at some point thousands of clients. We can find articles on the web about the benefits of using wordpress platform to build webapps. However, I could not find discussion with counterarguments to user wordpress. As the platform the most important choice in webapp project, I would to know more about the pitfalls and harms for choosing wordpress. The question is: What are the benefits and harms for choosing wordpress as a development platform for a webapp that need to be integrated with other system (backend systems) and to handle thousands of users (does it scale up?)?

  • How to give you website customers a secure feeling

    - by Saif Bechan
    I was wondering how you can give your website customers the confidence that you are not tinkering with the database values. I am planning on running a website which falls in the realm of an online game. There is some kind of credit system involved that people have to pay for. Now I was wondering how sites like this ensure there customers that there is no foul play in the database itself. As I am the database admin i can pretty much change all the values from within without anyone knowing i did. Hence letting someone win that does not rightfully is the winner. Is it maybe an option to decrypt en encrypt the credits people have so i can't change them. Or is there maybe a company i can hire that checks my company for foul play.

  • How to set up 3rd party developer portal

    - by Michael
    I am developing a web service and depend on 3rd party developers to write client applications for it. I need to set a developer portal, a web site where existing and potential developers would find documentation html pages doc files for download libraries downloads wiki forums support ticketing system. There should be a public part and a part protected by login. I want only logged in users to submit tickets, for example. I don't want to host it. I would prefer a generic design based on a sensible template, where I can add minimal customization, such as logo. I don't want to add code to get any of the above functionality. I will do all that if necessary, but I'd hope there would be an online service to do thing like that. What services would you guys recommend?

  • possible to create sql query with table wildcards?

    - by Rees
    this is probably a simple question, but i have been unable to find a solution online, any help would be much appreciated. I'm trying to create an SQL query in PHP and would like to somehow apply a wild card to the TABLE filter... something perhaps like.... select * from %table%. However, I have only so far been able to see filters for column values not table names. as an example i would have tables such as: jan_table_1 feb_table_1 jan_table_2 feb_table_2 and would want to say, select only tables with a "jan" prefix... or "1" suffix. Is there a quick and easy solution to this that I have not seen? Thanks in advance!

  • Multiple merchant accounts with Activemerchant gem.

    - by sosborn
    I am developing a rails site that will allow a group of merchants (5 - 10) to accept credit card orders online. I plan on using the Activemerchant gem to handle the processing. In this case, each merchant will have their own merchant accounts to handle the payments. Storing banking information like that is not something I am a fan of. This could be solved by queing orders and allowing the merchant to log in to the site, input their credentials and process the order. However, if I go that route then it seems to me that I would have to store the customers' credit card information temporarily until the merchant has the opportunity to log in and process the order, which to me is the greater evil. Has anyone dealt with this situation? If so, what are the options available and what pitfalls should I look out for? In my mind, security customer credit card information is priority number one with the merchant account information a close second.
