  • How to Get Current Weather via Web Services

    - by Brandon
    I am attempting to get the current weather given a zip code or a set of latitude/longitude coordinates. It appears that best practice to do this (and how NOAA does it) is to get the XML feed for a weather station. Example: http://www.weather.gov/xml/current_obs/KEDW.xml The only problem is that NOAA doesn't provide a good way to find the closest weather station given a zip code or coordinates and I did not see any hosted web services out there that will provide this mapping. Does anyone know of any web services to get the nearest weather station given a zip code or coordinate input? If not, does anyone have any great solutions to look into that provide similar information as NOAA does but takes in a zip code or coordinates?

  • Python progression path - From apprentice to guru

    - by Morlock
    Hi all, I've been learning, working, and playing with Python for a year and a half now. As a biologist slowly making the turn to bio-informatics, this language has been a the very core of all the major contributions I have made in the lab. (bash and R scripts have helped some too. My C++ capabilities are very not functional yet). I more or less fell in love with the way Python permits me to express beautiful solutions and also with the semantics of the language that allows such a natural flow from thoughts to workable code. What I would like to know from you is your answer to a kind of question I have seldom seen in this or other forums. Let me sum up what I do NOT want to ask first ;) I don't want to know how to QUICKLY learn Python Nor do I want to find out the best way to get acquainted with the language Finally, I don't want to know a 'one trick that does it all' approach. What I do want to know your opinion about, is: What are the steps YOU would recommend to a Python journeyman, from apprenticeship to guru status (feel free to stop wherever your expertise dictates it), in order that one IMPROVES CONSTANTLY, becoming a better and better Python coder, one step at a time. The kind of answers I would enjoy (but feel free to surprise the readership :P ), is formatted more or less like this: Read this (eg: python tutorial), pay attention to that kind of details Code for so manytime/problems/lines of code Then, read this (eg: this or that book), but this time, pay attention to this Tackle a few real-life problems Then, proceed to reading Y. Be sure to grasp these concepts Code for X time Come back to such and such basics or move further to... (you get the point :) This process depicts an iterative Learn/Code cycle, and I really care about knowing your opinion on what exactly one should pay attention to, at various stages, in order to progress CONSTANTLY (with due efforts, of course). If you come from a specific field of expertise, discuss the path you see as appropriate in this field. Thanks a lot for sharing your opinions and good Python coding!

  • Is this so bad when using MySQL queries in PHP?

    - by alex
    I need to update a lot of rows, per a user request. It is a site with products. I could... Delete all old rows for that product, then loop through string building a new INSERT query. This however will lose all data if the INSERT fails. Perform an UPDATE through each loop. This loop currently iterates over 8 items, but in the future it may get up to 15. This many UPDATEs doesn't sound like too good an idea. Change DB Schema, and add an auto_increment Id to the rows. Then first do a SELECT, get all old rows ids in a variable, perform one INSERT, and then a DELETE WHERE IN SET. What is the usual practice here? Thanks

  • Objective-C runtime reflection (objc_msgSend): does it violate the iPhone Developer License Agreemen

    - by GamingHorror
    Does code like this (potentially) violate the iPhone Developer License Agreement? Class clazz = NSClassFromString(@"WNEntity"); id entity = [clazz entityWithImage:@"Icon.png"]; SEL setPositionSelector = NSSelectorFromString(@"setPosition:"); objc_msgSend(entity, setPositionSelector, CGPointMake(200, 100)); I'm working on code that dynamically allocates classes from XML and calls methods on them via objc_msgSend. It's just very convenient constructing my objects that way but it worries me because i have no idea whether this is ok or violates the License by dynamically executing code or maybe even calling private (?) API functions. They wouldn't be documented if they were private, right? Can someone shed some light on this? Have you had an App approved or rejected using code similar to the above? I'm pretty sure that this is ok but i wan't to hear it from someone else! :)

  • MVVM Madness: Commands

    - by JP
    I like MVVM. I don't love it, but like it. Most of it makes sense. But, I keep reading articles that encourage you to write a lot of code so that you can write XAML and don't have to write any code in the code-behind. Let me give you an example. Recently I wanted to hookup a command in my ViewModel to a ListView MouseDoubleClickEvent. I wasn't quite sure how to do this. Fortunately, Google has answers for everything. I found the following articles: http://blog.functionalfun.net/2008/09/hooking-up-commands-to-events-in-wpf.html http://joyfulwpf.blogspot.com/2009/05/mvvm-invoking-command-on-attached-event.html http://sachabarber.net/?p=514 http://geekswithblogs.net/HouseOfBilz/archive/2009/08/27/adventures-in-mvvm-ndash-binding-commands-to-any-event.aspx http://marlongrech.wordpress.com/2008/12/13/attachedcommandbehavior-v2-aka-acb/ While the solutions were helpful in my understanding of commands, there were problems. Some of the aforementioned solutions rendered the WPF designer unusable because of a common hack of appending "Internal" after a dependency property; the WPF designer can't find it, but the CLR can. Some of the solutions didn't allow multiple commands to the same control. Some of the solutions didn't allow parameters. After experimenting for a few hours I just decided to do this: private void ListView_MouseDoubleClick(object sender, MouseButtonEventArgs e) { ListView lv = sender as ListView; MyViewModel vm = this.DataContext as MyViewModel; vm.DoSomethingCommand.Execute(lv.SelectedItem); } So, MVVM purists, please tell me what's wrong with this? I can still Unit test my command. This seems very practical, but seems to violate the guideline of "ZOMG... you have code in your code-behind!!!!" Please share your thoughts. Thanks in advance.

  • Application threads vs Service threads

    - by zerayaqob
    What are the advantages/disadvantages in placing a lengthy network access code in a thread in an activity or a thread in a service? How would it affect the application? I am writing a streaming audio player and from what I've read so far putting the code in a service will still end up blocking the application so a new thread is needed, does anyone know if it makes more sense to put this piece of code in a service. Thanks

  • Apache Config with Wildcard/Non-Wildcard Subdomain Mix

    - by SoupNutsy
    I have the domain, we'll call it "mydomain.com" and I want the following virtual hosts set up to resolve in the following way: mydomain.com / www.mydomain.com to point to /var/www/ dev.mydomain.com to point to /var/www/dev/ *.mydomain.com (all other subdomains) to point to /var/www/old My apache configuration is currently set up as: NameVirtualHost 1.2.3.4:80 <VirtualHost 1.2.3.4:80> ServerAlias *.mydomain.com DocumentRoot /var/www/old </VirtualHost> <VirtualHost 1.2.3.4:80> ServerName mydomain.com ServerAlias www.mydomain.com DocumentRoot /var/www </VirtualHost> <VirtualHost 1.2.3.4:80> ServerAlias dev.mydomain.com DocumentRoot /var/www/dev </VirtualHost> Unfortunately, this is not working as I expected. With this configuration, only the first (wildcard) VirtualHost entry works properly. What is the right way to configure Apache to do this?

  • What are common anti-patterns when using VBA

    - by Ahmad
    I have being coding a lot in VBA lately (maintenance and new code), specifically with regards to Excel automation etc. = macros. Typically most of this has revolved around copy/paste, send some emails, import some files etc. but eventually just ends up as a Big ball of mud As a person who values clean code, I find it very difficult to produce 'decent' code when using VBA. I think that in most cases, this is a direct result of the macro-recorder. Very helpful to get you started, but most times, there are one too many lines of code that achieve the end result. Edit: The code from the macro-recorder is used as a base to get started, but is not used in its entirety in the end result I have already created a common addin that has my commonly used subroutines and some utility classes in an early attempt to enforce some DRYness - so this I think is a step in the right direction. But I feel as if it's a constant square peg, round hole situation. The wiki has an extensive list of common anti-patterns and what scared me the most was how many I have implemented in one way or another. The question Now considering, that my mindset is OO design, what some common anti-patterns and the possible solutions when designing a solution (think of this - how would designing a solution using Excel and VBA be different from say a .net/java/php/.../ etc solution) ; and when doing common tasks like copying data, emailing, data importing, file operations... etc An anti-pattern as defined by Wikipedia is: In software engineering, an anti-pattern (or antipattern) is a pattern that may be commonly used but is ineffective and/or counterproductive in practice

  • Visual Sourcesafe, sharing: commits to wrong location

    - by Snake
    I have a project under my management. It has the following structure: $/Code/MainSolution $/Code/Branches I want to branch the MainSolution in $/Code/Branches So I do it, (it works perfectly), I set a working folder for that project and do a 'get latest'. But when I open that solution in Visual Studio 2005 it identifies every file as new (+ sign in front of the file) and when I commit it it goes to $/Data/NameOfTheBranch Why does it do that? Why doesn't it follow MY rules?

  • Moving from WCF RIA Beta to RC: best practices?

    - by Duncan Bayne
    I have an existing WCF RIA project built on the Release Candidate; I'm now moving to the Release version & have discovered many changes. David Scruggs made the following comment on his (MSDN) blog: "If you’ve written anything in SIlverlight 4 RIA Services, you’ll need to rewrite it. There has been a lot of refactoring and namespace moves." Having made a brief attempt to compile the old solution with the new RIA framework I'm inclined to agree. My current plan is to: remove the Silverlight Business Application projects from the Solution rebuild the EF4 items from the database create a new Silverlight Business Application project re-add the files (XAML, CS) from the old Silverlight Business Application project Does this sound like a reasonable approach? I think it's cleaner than trying to manually alter the existing project.

  • How do I make UIWebView show a pdf file from its own app?

    - by Aakburns
    I really need to make a UIWebView open up a specific PDF document that is in my project directory. I can't seem to find any tutorials on this. I found one, but the author was not specific about some of the code. I have to assume it's got to be quite a simple bit of code. Can someone help me code UIWebView to load a PDF? Thanks.

  • Force-directed graphing

    - by David
    Hello, I'm trying to write a force-directed or force-atlas code base for a graphing application I'm building for myself. Here is an example of what I'm attempting: http://sawamuland.com/flash/graph.html I managed to find some pseudo code to accomplish what I'd like on the Wiki Force-atlas article. I've converted this into ActionScript 3.0 code since it's a Flash application. Here is my source: var timestep:int = 0; var damping:int = 0; var total_kinetic_engery:int = 0; for (var node in list) { var net_force:int = 0; for (var other_node in list) { net_force += coulombRepulsion(node, other_node, nodeList); } for (var spring in list[node].relations) { net_force += hookeAttraction(node, spring, nodeList); } list[node].velocity += (timestep * net_force) * damping; list[node].position += timestep * list[node].velocity; total_kinetic_engery += list[node].mass * (list[node].velocity) ^ 2; } The problem now is finding pseudo code or a function to perform the the coulomb repulsion and hooke attraction code. I'm not exactly sure how to accomplish this. Does anyone know of a good reference I can look at...understand and implement quickly? Best.

  • oracle's pro*C compiler and gnu C (__builtin_va_list, __attribute__, etc)

    - by Charles Ma
    I'm compiling a database library with pro*C which converts the .ppc library file to a .c file that gcc can use. However, I'm getting a lot of errors in pro*C like the following PCC-S-02201, Encountered the symbol "__ attribute__ " when expecting one of the following ... , Encountered the symbol "__builtin_va_list" when expecting one of the following The missing symbols are from a chain of standard includes like stdio.h and stdlib.h. How do I get around this issue? The library I'm compiling came from an old solaris system that we're now upgrading (to a new solaris 10 system) and the header files don't seem to use these symbols. e.g. the newer .h files has typedef __builtin_va_list va_list while the old .h files has typedef void* va_list There are a lot of things like this so I'm reluctant to go and fix all of them manually with a typedef

  • .NET COM Interop with references to other libraries

    - by user262190
    Hello,I'm up against a problem when loading a class in a managed library from a COM Interop library. basically I have some Unmanaged C++ code and a COM Interop library written in C#. And finally a 3rd library which is referenced by the COM Interop library which contains a class: public class MyClass{ public MyClass(){} } What I'd like to do is from my unmanaged c++ code, call a function in the Interop library The C++ code doesn't need to know of the existence of the third library, it's only used within the Interop. Init(){ MyClass _class = new MyClass(); } for some reason this line in Init fails "MyClass _class = new MyClass();", and I don't get very usefull error messages, all I have to go on is a few of these in my output window: "First-chance exception at 0x7c812afb in DotNet_Com_Call.exe: Microsoft C++ exception: [rethrow] at memory location 0x00000000.." and the HRESULT of the "HRESULT hr = pDotNetCOMPtr-Init();" line in my C++ code is "The system cannot find the specified file" I'm new to COM so if anyone has any ideas or pointer to get me going the right direction, I'd appreciate it, Thanks

  • running asp.net 3.5 and asp.net 2.0 in same site

    - by cori
    We're running ASP.Net 2.0 on our corporate web site, and I'd like to get it up to ASP.Net 3.5 as smoothly as possible. The project/solution architecture in VS 2005 is an ASP.Net 2.0 web project and an .Net 2.0 data access layer project which is used by the site code. Upon opening the projects in a new VS 2008 solution they seemed to be converted to .Net 3.5 with a minimum of fuss - they built correctly out of the box, deployed successfully, and seem to work just fine, which is exactly as I would expect given that .Net 2.0 and 3.5 share a common runtime. The major difference after the conversion is that the web.config file's referenced dlls are now the 3.5 versions. What I would like to do is to update the site piecemeal; as I make modifications to a given page send the 3.5 verson of that page over to our webserver and not update the whole site at once. In testing on our dev box this approach seems to be working fine - the site code is interacting with the .Net 3.5 data access layer without difficulty, a handful of pages are running 3.5 page-behind code (by this I mean that they're running assemblies built in VS 2008 - the site is using single-page assemblies for code behind), the 3.5 web.config is in place, and the bulk of the site is running code-behind assemblies built in VS2005. Everything looks great. Which makes me worried that I'm missing something. Is this architecture workable, or is there a problem lying is wait for m that I haven't considered?
