  • Career path decisions

    - by MindFold
    Hi all, I'm on a verge of quitting my current job as a .NET programmer. i'm 25 years old and have been a .NET programmer in the past 5-6 years, but now i wonder if maybe i should take this opurtunity and try some other things, like RT\Embedded or Driver development. My pro\cons: i love .NET since you can write enterprise systems with it, learn cool development methodologies and practice many patterns i want to learn RT\Embedded\Driver since its at the heart of so many things and i'm feeling this is a black hole for me. My question are: Is making career leaps a good idea? How can i manage to get myself into a job in RT\Embedded as my whole Resume has c# written all over it. What should i bet my cards on this days? android? java? flash? silverlight? etc?

  • C-library consists of asynchronous DNS resolver

    - by egiakoum1984
    Need to find a asynchronous DNS resolver implemented in C (except Sofia Resolver) which supports DNS queries for NAPTR, SRV and A records. It would be desired to support internal caching. Any suggestions/recommendations? Currently looking at ldns which supports NAPTR, SVC and A queries. But, If I have understood correctly, it is not asynch DNS resolver.

  • How much does Website Development cost nowadays?

    - by Andreas Grech
    I am thinking of setting up my own freelance business but coming from a workplace that offers a particular service to huge clients, I do not know what are the current charges for websites are nowadays. I know that as technology just keeps changing and changing (most of the time, for the better...), the amount you charge for a single website is constantly differing. Like for example, I don't think static websites (with just static html pages) are that expensive today, no? (as i said, I might be mistaken since I haven't really touched on this freelance industry yet) So, freelance web-developers out there, can you give me estimates on how much you charge for your clients? Some examples of websites that I want to know an approx charge: ~10 static html pages ~10 dhtml pages (with maybe a flasy menu on the top/side) Database driven websites with a standard CMS (be it the one you developed, or an existing one) Database driven but with a custom-built cms for the particular client Using an existing template for a design Starting the design from scratch etc... I know that the normally clients don't really care about the technologies used to construct their websites, but do you charge differently according to which technology you use to build the website with?; as in, is the technology a factor when setting the price? ...being ASP.Net, PHP, Ruby On Rails etc... Also, how do you go on about charging your clients for your services? What are the major factors that you consider when setting a price tag for a website to a client ? And better yet, how do you even find prospective clients? <= [or should I leave this question for a different post?] Btw, in your post, also mention some numbers (in cash values, be it in USD, GBP, EUR or anything) because I want to be able to take calculate some averages from this post when some answers stack up

  • Enterprise Native Mobile Application Development

    - by ahsteele
    I tend to believe that developing mobile applications in an enterprise environment is best suited by developing intranet web applications. That said I have been asked to think about whether there are specific enterprise applications that could only be accomplished or would be more successful as native applications. I am curious as to what the Stack Overflow community thinks. Note: As an organization we primarily use BlackBerry devices but are other platform curious.

  • wpf & validation application block > message localization > messageTemplateResource Name&Type

    - by Shaboboo
    I'm trying to write validation rules for my data objects in a WPF application. I'm writing them in the configuration file, and so far they are working fine. I'm stumped on how to localize the messages using messageTemplateResourceName and messageTemplateResourceType. What I know is that the strings can be writen in a resource file, given a name and referenced by that name. I get the idea, but i haven't been able to make this work. <ruleset name="Rule Set"> <properties> <property name="StringValue"> <validator lowerBound="0" lowerBoundType="Ignore" upperBound="25" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="msg1" messageTemplateResourceType="Resources" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.EnterpriseLibrary.Validation" name="String Length Validator" /> </property> </properties> </ruleset> Where is the resource file and what value do I pass to messageTemplateResourceType? I have tried writing the messages in the shell project's resource file but no sucess trying to retrieve the value. I only get the default built-in message. I've tried messageTemplateResourceType="typeof(Resources)" messageTemplateResourceType="Resources" messageTemplateResourceType="Resources.resx" messageTemplateResourceType="typeof(Shell)" messageTemplateResourceType="Shell" messageTemplateResourceType="Shell, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" I've also tried adding a new resource file in the shell project, and adding a resource file to the data object's library. I'm all out of ideas Does anyone have any suggestions? I'm not even married to the idea of resource files, so if there are other ways to localize these messages I'd love to know! thanks

  • Is there a Scheduler/Calendar JS Widget library?

    - by Ravi Chhabra
    I am looking for some JavaScript based component to be used as a course scheduler which would be a cross between Google Calendar and the login time. I do not know if the right term for this is Course Scheduler but I shall describe this in more detail here. Course Scheduler The widget would be used to enter date and times of a course, as an example if I run a programming course 3 days a week on Mon, Tue and Wed every 7:00 am to 9:00am, 2 hours every day from 1st September to 30th November. I could answer various questions and the course data would be displayed in the calendar. It would also allow for non pattern based timings where each week is different from the other week etc. Question So would I end up creating something from scratch? Would it be sensible to use Google Calendar API for this? I did a Google search for some widgets, but I believe I need better keywords, as I could not find anything close to what I am looking for. Any tips? Commercial libraries would also work for me. Thanks.

  • Designing DAOs around a JSON API for iPhone Development

    - by Bob Spryn
    So I've been trying to design a clean way of grabbing data for my models in iPhone land. All the data for my application is coming from JSON API's. So right now when a VC needs some models, it does the JSON call itself (asynch) and when it receives the data, it builds the models. It works, but I'm trying to think of a cleaner method whereby the DAO's retrieve the information for me and return the models, all in an async manner. My initial thought is build a protocol for my DAOs, such that the VC would instantiate a DAO and make itself the delegate. When you requested data [DAOinstance getAllUsers] the DAO would do all the network request stuff, and then when it had the data, it would call a method on its delegate (the VC) to pass the data. So I think that's a cool solution, but realized that if I needed to use the same DAO for different purposes in the same VC, my delegate method would have to branch logic depending on which DAO instance initiated the request. So my second thought was to be able to pass 'handler' selectors to the DAO object a la typical javascript patterns. So instead of an official protocol, I would say something like [DAOinstance getAllUsersWithSelector:"TheHandlerFunctionOnMyVC:"] Then when the DAO completed its network activities, it would call the passed selector on the VC, and pass the data back. So am I headed in the wrong direction entirely here? Seems like maybe an ok way to go. Any pointers or articles on designing this kind of data layer would be sweet. Thanks! Bob

  • Rails with passenger only runs in development

    - by Ignace
    Hey, I have a problem on one of our webservers. I'll try to explain it as clear as possible, but I'm not 100% aware of all the configuration of the server. There are 2 sites running next to eachother (blcc_preprod and blcc_prod), so in the 'sites-enabled' of apache this i have a file 'blcc' like this: <VirtualHost *:80> DocumentRoot /opt/dn/blcc/www RailsBaseURI /blcc_preprod RailsBaseURI /blcc_prod RailsEnv production </VirtualHost> My config/environments/production.log (from both) looks like this(I removed all comments, because it messes with the layout) config.cache_classes = true config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true config.action_view.cache_template_loading = true config.log_level = :debug The weird thing is, that my production log dates from months ago, so something is really wrong. Could someone help? If you need more info, just ask. Thanks! Edit: Error.log from apache show the normal output for a event to the server (the situation here is that the webserver plugs in to another business (java) server via a framework) Access.log is empty Content from other_vhosts_access.log after we surf to ip/blcc_preprod is the following blcc.localdomain:80 192.168.21.194 - - [25/May/2010:08:33:04 +0200] "GET/ blcc_preprod HTTP/1.1" 500 594 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)"

  • Poco library for c++, declare namespace for custom element

    - by Mikhail
    I want to create an XML document by building a DOM document from scratch, with syntax like: AutoPtr<Document> doc = new Document; AutoPtr<Element> root = doc->createElement("root"); doc->appendChild(root); AutoPtr<Element> element1 = doc->createElementNS("http://ns1", "ns1:element1"); root->appendChild(element1); AutoPtr<Element> element2 = doc->createElementNS("http://ns1", "ns1:element2"); root->appendChild(element2); DOMWriter writer; writer.setNewLine("\n"); writer.setOptions(XMLWriter::PRETTY_PRINT); writer.writeNode(std::cout, doc); But, when I write it, I get next result: <root> <ns1:element1 xmlns:ns1="http://ns1"/> <ns1:element2 xmlns:ns1="http://ns1"/> </root> So namespace ns1 declared two times, and I want to declare it inside "root" element. Is there way to get next representation: <root xmlns:ns1="http://ns1"/> <ns1:element1/> <ns1:element2/> </root>

  • Help for Platform plus Plugin development by J2ee

    - by echo
    Hi, everybody. I want to develop a monitor platform which can monitor many different subjects such as database, OS, middle ware etc. The system includes two parts: 1. Report center(Show some useful chart and report) 2. Collector(Collect information from monitored subject) For the time being, I just want to monitor some parameters of oracle and Linux. And I will add more monitor subject like MS SqlServer, IBM Db2 ect. later. I need a good architecture so I can easily add new monitor module and not to disturb original framework too much. I want to develop it by the method of “Platform + plugin”. A plugin should have its own UI, setting part and something else. I plan to use struts2 + spring + hibernate to develop report center. I am not very sure how to do design this architecture for I have any “Platform + plugin” experience. I ever googled some information such as OSGI and Portlet. I am not sure which one should be my best choice. Can anyone give me some instruction about it. Your help will be appreciated.

  • openssl crypto library - base64 conversion

    - by Hassan Syed
    I'm using openssl BIO objects to convert a binary string into a base64 string. The code is as follows: void ToBase64(std::string & s_in) { BIO * b_s = BIO_new( BIO_s_mem() ); BIO * b64_f = BIO_new( BIO_f_base64() ); b_s = BIO_push( b64_f , b_s); std::cout << "IN::" << s_in.length(); BIO_write(b_s, s_in.c_str(), s_in.length()); char * pp; int sz = BIO_get_mem_data(b_s, &pp); std::cout << "OUT::" << sz << endl; s_in.assign(pp,sz); //std::cout << sz << " " << std::string(pp,sz) << std::endl; BIO_free (b64_f); // TODO ret error potential BIO_free (b_s); // } The in length is either 64 or 72. However the output is always 65, which is incorrect it should be much larger than that. The documentation isn't the best in the world, AFAIK the bio_s_mem object is supposed to grow dynamically. What am I doing wrong ?

  • Scope of "library" methods

    - by JS
    Hello, I'm apparently laboring under a poor understanding of Python scoping. Perhaps you can help. Background: I'm using the 'if name in "main"' construct to perform "self-tests" in my module(s). Each self test makes calls to the various public methods and prints their results for visual checking as I develop the modules. To keep things "purdy" and manageable, I've created a small method to simplify the testing of method calls: def pprint_vars(var_in): print("%s = '%s'" % (var_in, eval(var_in))) Calling pprint_vars with: pprint_vars('some_variable_name') prints: some_variable_name = 'foo' All fine and good. Problem statement: Not happy to just KISS, I had the brain-drizzle to move my handy-dandy 'pprint_vars' method into a separate file named 'debug_tools.py' and simply import 'debug_tools' whenever I wanted access to 'pprint_vars'. Here's where things fall apart. I would expect import debug_tools foo = bar debug_tools.pprint_vars('foo') to continue working its magic and print: foo = 'bar' Instead, it greets me with: NameError: name 'some_var' is not defined Irrational belief: I believed (apparently mistakenly) that import puts imported methods (more or less) "inline" with the code, and thus the variable scoping rules would remain similar to if the method were defined inline. Plea for help: Can someone please correct my (mis)understanding of scoping regards imports? Thanks, JS

  • st-ordering library function?

    - by chang
    I'm in the search for an implementation of an ear-decomposition algorithm (http://www.ics.uci.edu/~eppstein/junkyard/euler/ear.html). I examined networkx and didn't find one. Although the algorithm layout is vaguely in my mind, I'd like to see some reference implementation, too. Side problem: First step could be an st-ordering of a graph. Are there any implementations for st-ordering algorithms you know? Thanks for your input. I'd really like to contribute e.g. to networkx by implementing the ear-decomposition algorithm in python.

  • iPhone Development - Using NSPredicate to retrieve most recently added record from CoreData

    - by Mustafa
    I want to retrieve the most recently added record from CoreData. I was wondering if that's possible using NSPredicate? If so, how? e.g. i have a one-to-many relationship between Department and Staff, and i want to fetch the Staff record that was most recently employed. The Staff table has a date field which can be used. I don't want to fetch all the Staff records and then look for the right one. Note that CoreData stores the related records in an NSSet.
