• Experimenting with other search engines

  - by Bill Graziano

  I’ve been a Google user so long I can hardly remember what I used before it.  Alta Vista maybe?  Or Yahoo.  I’ve tried Bing off and on but it never really stuck.  I probably care more about search engines than your average user because of their impact on SQLTeam.com.  Lately I’ve been trying two other search engines and actually switched to one of them. I’ve played with Blekko a little in the past.  They have some interesting ways to “slice up” your results.  For example, searching on “SQL Server /blogs /date” should just search all the recently updated blogs.  Those two extra words on the search are slashtags.  The full list of slashtags runs from /forums to just see forums to /twitter to /nikon to /reviews and on and on and on.  I laughed when I saw they had slashtags for both liberal and conservative.  I’d hate to find any search results that don’t match my existing worldview :)  You can also create your own slashtags.  I created a mini-search engine for the SQL Server blogs that I read.  You can search it for “backup” at http://blekko.com/ws/backup+/billgraziano/sql-sites.  I uploaded my OPML and it limited the search to just those sites.  It seems like the site is focusing more on curating results and less on algorithms.  This is an interesting site for those power searchers.  There are some great ways to curate results using slashtags.  For 99% of my searches (type words, click on one of the first few links) slashtags are overkill.  They do have some good information on page and site ranking though so I’ll probably send some time looking through that. Blekko recently got my attention again when they said they were banning “content farms” - and that includes eHow and experts-exchange.  I always feel used when I click on a link to EE and find myself scrolling all the way to the bottom to see if I can find the answer.  Sometimes it’s there but sometimes it tells me I need to pay first.  I’ve longed for a way to always exclude certain sites.  Blekko might be taking a hammer to a problem that needs a scalpel but it’s an interesting choice.  (And some of the comments in the TechCrunch link are interesting if you’re a search nerd.) DuckDuckGo is an odd name for a search engine.  Their big hook is that they don’t have search history.  If you wade through your Google account you can probably find the page where it stores your search history.  It was pretty enlightening to find mine.  It was easy to disable but that got me started looking at other search engines.  DDG (or DukGo) just feels like Google used to in the old days.  The results are good enough and the site is fast. Searches will return a snippet from WikiPedia or other site (like StackOverflow) at the top.  I think the idea is to answer the question without needing to visit the site.  I’m not sure that’s a good thing for SQLTeam.com. The only thing I really miss is image search.  You can add a “!i” at the end of any search and it will search the images on Bing.  Bing doesn’t have a great image search but it works for most of what I need.  They call these exclamation marks “!bangs” and they are kinda, sorta like slashtags.  I’ve been using DuckDuckGo now for a few weeks and I’m pretty happy with it.  I use Chrome for my browser and it was an easy switch to make.  It’s still a little surprising seeing my search results come up in a different format.  I’m starting to get used to it though.

• Parameterized StreamInsight Queries

  - by Roman Schindlauer

  The changes in our APIs enable a set of scenarios that were either not possible before or could only be achieved through workarounds. One such use case that people ask about frequently is the ability to parameterize a query and instantiate it with different values instead of re-deploying the entire statement. I’ll demonstrate how to do this in StreamInsight 2.1 and combine it with a method of using subjects for dynamic query composition in a mini-series of (at least) two blog articles. Let’s start with something really simple: I want to deploy a windowed aggregate to a StreamInsight server, and later use it with different window sizes. The LINQ statement for such an aggregate is very straightforward and familiar: var result = from win in stream.TumblingWindow(TimeSpan.FromSeconds(5))               select win.Avg(e => e.Value); Obviously, we had to use an existing input stream object as well as a concrete TimeSpan value. If we want to be able to re-use this construct, we can define it as a IQStreamable: var avg = myApp     .DefineStreamable((IQStreamable<SourcePayload> s, TimeSpan w) =>         from win in s.TumblingWindow(w)         select win.Avg(e => e.Value)); The DefineStreamable API lets us define a function, in our case from a IQStreamable (the input stream) and a TimeSpan (the window length) to an IQStreamable (the result). We can then use it like a function, with the input stream and the window length as parameters: var result = avg(stream, TimeSpan.FromSeconds(5)); Nice, but you might ask: what does this save me, except from writing my own extension method? Well, in addition to defining the IQStreamable function, you can actually deploy it to the server, to make it re-usable by another process! When we deploy an artifact in V2.1, we give it a name: var avg = myApp     .DefineStreamable((IQStreamable<SourcePayload> s, TimeSpan w) =>         from win in s.TumblingWindow(w)         select win.Avg(e => e.Value))     .Deploy("AverageQuery"); When connected to the same server, we can now use that name to retrieve the IQStreamable and use it with our own parameters: var averageQuery = myApp     .GetStreamable<IQStreamable<SourcePayload>, TimeSpan, double>("AverageQuery"); var result = averageQuery(stream, TimeSpan.FromSeconds(5)); Convenient, isn’t it? Keep in mind that, even though the function “AverageQuery” is deployed to the server, its logic will still be instantiated into each process when the process is created. The advantage here is being able to deploy that function, so another client who wants to use it doesn’t need to ask the author for the code or assembly, but just needs to know the name of deployed entity. A few words on the function signature of GetStreamable: the last type parameter (here: double) is the payload type of the result, not the actual result stream’s type itself. The returned object is a function from IQStreamable<SourcePayload> and TimeSpan to IQStreamable<double>. In the next article we will integrate this usage of IQStreamables with Subjects in StreamInsight, so stay tuned! Regards, The StreamInsight Team

• iPhone: Software Development And Distribution

  - by xsl

  I have a few quick questions about the iPhone software development. I did some research about the topic, but there are a few specific things I would like to ask here, because I will have to estimate the cost of the required hardware and software, before I am allowed to buy anything. I never did any Mac development nor have I ever owned an iPhone, so needless to say this is quite hard for me. I will buy an iMac mini with 2 GB RAM for iPhone development. I will have to use it at the same time as my regular PC, but the majority of the time I won't use the Mac at all. Do I have to buy an additional monitor, a mouse and a keyboard or is there a better solution? I will have to port a C library to the iPhone platform and develop an iPhone application that uses the ported library. Do I need anything else than the iPhone SDK to do this? If I use an external library (see above), can I test the application with the integrated emulator, or is it recommend to buy the device? In a later phase of the project I will have to buy an iPhone, but I will have to wait until the iPhone 4 is released here in Europe, because the application requires a camera. In addition to this I will have to send data to a remote webservice. Aside from these two things I don't require any other features. Can I just buy the iPhone online from another country (the iPhones here are sim locked), or should I buy one with a contract? When the application is ready, it will be installed on a few iPhones owned by our customer. Because of security reasons it is crucial that there is no third party involved in this process (i.e. the application should not be distributed on the app store). Is this possible?

• calling CreateFile, specifying FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE.

  - by alexander-daniels

  Before I describe my problem, here is a description of the program I'm writting: This is a C++ application. The purpose of my program is to create file on RAM memory. I read that if specify FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE when creating file it will be loaded direct to the RAM memory. One of blogs that talk about is this one: http://blogs.msdn.com/larryosterman/archive/2004/04/19/116084.aspx I have built a mini-program, but it not achieves the goal. Instead, it creates a file on hard-drive on directory I specify. Here's my program: void main () { LPCWSTR str = L"c:\temp.txt"; HANDLE fh = CreateFile(str,GENERIC_WRITE,0,NULL,CREATE_ALWAYS, FILE_ATTRIBUTE_TEMPORARY | FILE_FLAG_DELETE_ON_CLOSE,NULL); if (fh == INVALID_HANDLE_VALUE) { printf ("Could not open TWO.TXT"); return; } DWORD dwBytesWritten; for (long i=0; i<20000000; i++) { WriteFile(fh, "This is a test\r\n", 16, &dwBytesWritten, NULL); } return; } I think there problem in CreateFile function, but I can't fix it. Please help me.

• CPAN mirroring problem in cpan::mirrror

  - by user304122

  I am on a corporate PC that forces mcshield on everything that moves. I get blocked when trying to mirror on :- . . . . . . authors/id/J/JV/JV/EekBoek-2.00.01.tar.gz ... updated authors/id/J/JV/JV/CHECKSUMS ... updated Could not stat tmpfile '/cygdrive/t/cpan_mirror/authors/id/J/JW/JWIED/Mail-IspMailGate-1.1013.tar.gz-4712': No such file or directory at /usr/lib/perl5/site_perl/5.10/LWP/UserAgent.pm line 851. authors/id/J/JW/JWIED/Mail-IspMailGate-1.1013.tar.gz At this point, I get the Virus scanner mcshield sticking its Awr in.

Just cannot get it to skip the module failing module to complete other WIED modules. Any ideas ?? .

• Metaprogramming - self explanatory code - tutorials, articles, books

  - by elena

  Hello everybody, I am looking into improving my programming skils (actually I try to do my best to suck less each year, as our Jeff Atwood put it), so I was thinking into reading stuff about metaprogramming and self explanatory code. I am looking for something like an idiot's guide to this (free books for download, online resources). Also I want more than your average wiki page and also something language agnostic or preferably with Java examples. Do you know of such resources that will allow to efficiently put all of it into practice (I know experience has a lot to say in all of this but i kind of want to build experience avoiding the flow bad decisions - experience - good decisions)? EDIT: Something of the likes of this example from the Pragmatic Programmer: ...implement a mini-language to control a simple drawing package... The language consists of single-letter commands. Some commands are followed by a single number. For example, the following input would draw a rectangle: P 2 # select pen 2 D # pen down W 2 # draw west 2cm N 1 # then north 1 E 2 # then east 2 S 1 # then back south U # pen up Thank you!

• Using Unicode in fancyvrb’s VerbatimOut

  - by Konrad Rudolph

  Problem VerbatimOut from the “fancyvrb” package doesn’t play nicely with UTF-8 characters. Minimal working example: \documentclass{minimal} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{fancyvrb} \begin{document} \begin{VerbatimOut}{\jobname.test} é \end{VerbatimOut} \input{\jobname.test} \end{document} Error message When compiled using pdflatex mini, this gives the error File ended while scanning use of \UTFviii@three@octets. A different error occurs when the sole occurrence of é above is replaced by something else, e.g. é */: Package inputenc Error: Unicode char \u8:### not set up for use with LaTeX. – indicating that in this case, LaTeX succeeds in reading a multi-byte UTF-8 character, but not knowing what to do with it (i.e. it’s the wrong character). In fact, when I open the produced .test file manually, it contains the character é, but in Latin-1 encoding! Proof: when I open the files in a hex editor, I get the following: Original file: C3 A9 (corresponds to LATIN SMALL LETTER E WITH ACUTE in UTF-8) Written file: E9 (corresponds to é in Latin-1) Question How to set VerbatimOut up correctly? filecontents* (from “filecontents”) shows that it can work. Unfortunately, I don’t understand either code so I cannot fix fancyvrb’s code by replicating the logic from filecontents manually. I also cannot use filecontents* instead of VerbatimOut because the former doesn’t work within a \newenvironment, while the latter does. (Oh, by the way: vanilla Verbatim instead of VerbatimOut also works as expected. The error seems to occur when writing the file, not when reading the verbatim input)

• RelayCommand sender from ItemsControl item

  - by Padu Merloti

  I've been using MVVM's RelayCommand with success to bind actions to XAML, but I'm having a small problem with my ItemsControl. <ItemsControl ItemsSource="{Binding Devices}" > <ItemsControl.ItemTemplate> <DataTemplate> <Grid Width="100" Margin="4" > <Button Command="{Binding Path=SelectDeviceCommand}" > <Grid> <Image Source="img_small.png"></Image> <Image Source="{Binding Path=Logo}" /> </Grid> </Button> </Grid> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> In my view model: public RelayCommand SelectDeviceCommand { get; set; } private ObservableCollection<Device> Devices; Devices = CreateListOfDevices(); private void InitializeCommands() { SelectDeviceCommand = new RelayCommand((s) => MessageBox.Show(s.ToString())); } How do I define my SelectDeviceCommand in my view model in order to receive object that is bound to that item? My SelectDeviceCommand is not even being called... (but that I guess is because I need to make my Device a mini-viewmodel and implement the SelectDeviceCommand in it, is that correct?)

• Strange behavior due to wx.Frame.SetTitle

  - by Anurag Uniyal

  In a wxPython application, which i am porting to Mac OSX, I set title of app frame every 500msec in update UI event, and due to that all the panels and windows are refreshed. That seems strange to me and almost halts my application which has many custom drawn controls and screens. I wanted to know what could be the reason behind it, is it normal for MAC? Here is a self-constrained script which replicates the scenario using timers. It keeps on printing "on paint" every 500ms because in timer I set title every 500ms. import wx app = wx.PySimpleApp() frame = wx.Frame(None, title="BasePainter Test") painter = wx.Panel(frame) def onPaint(event): dc = wx.PaintDC(painter) print "onPaint" painter.Bind(wx.EVT_PAINT, onPaint) def loop(): frame.SetTitle(frame.GetTitle()) wx.CallLater(500, loop) loop() frame.Show(True) app.SetTopWindow(frame) app.MainLoop() My system details: >>> sys.version '2.5 (r25:51918, Sep 19 2006, 08:49:13) \n[GCC 4.0.1 (Apple Computer, Inc. build 5341)]' >>> wx.VERSION (2, 8, 10, 1, '') >>> os.uname() ('Darwin', 'agyeys-mac-mini.local', '9.8.0', 'Darwin Kernel Version 9.8.0: Wed Jul 15 16:55:01 PDT 2009; root:xnu-1228.15.4~1/RELEASE_I386', 'i386')

• Add objects in relationship not work using MagicalRecord saveWithBlock

  - by yong ho

  The code to perform a save block: [MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) { for (NSDictionary *stockDict in objects) { NSString *name = stockDict[@"name"]; Stock *stock = [Stock MR_createInContext:localContext]; stock.name = name; NSArray *categories = stockDict[@"categories"]; if ([categories count] > 0) { for (NSDictionary *categoryObject in categories) { NSString *categoryId = categoryObject[@"_id"]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"categoryId == %@", categoryId]; NSArray *matches = [StockCategory MR_findAllWithPredicate:predicate inContext:localContext]; NSLog(@"%@", matches); if ([matches count] > 0) { StockCategory *cat = [matches objectAtIndex:0]; [stock addCategoriesObject:cat]; } } } } } completion:^(BOOL success, NSError *error) { }]; The Stock Model: @class StockCategory; @interface Stock : NSManagedObject @property (nonatomic, retain) NSString * name; @property (nonatomic, retain) NSSet *categories; @end @interface Stock (CoreDataGeneratedAccessors) - (void)addCategoriesObject:(StockCategory *)value; - (void)removeCategoriesObject:(StockCategory *)value; - (void)addCategories:(NSSet *)values; - (void)removeCategories:(NSSet *)values; @end The json look like this: [ { "name": "iPad mini ", "categories": [ { "name": "iPad", "_id": "538c655fae9b3e1502fc5c9e", "__v": 0, "createdDate": "2014-06-02T11:51:59.433Z" } ], }, { "name": "iPad Air ", "categories": [ { "name": "iPad", "_id": "538c655fae9b3e1502fc5c9e", "__v": 0, "createdDate": "2014-06-02T11:51:59.433Z" } ], } ] Open the core data pro, You can see only stock with the name of "iPad air" has it's categories saved. I just can't figure out why. You can see in the saveWithBlock part, I first find in the context for the same _id as in json, and then add the category object in the relationship. It's working, but not all of them. Why is that?

• Ideal Multi-Developer Lamp Stack?

  - by devians

  I would like to build an 'ideal' lamp development stack. Dual Server (Virtualised, ESX) Apache / PHP on one, Databases (MySQL, PgSQL, etc) on the other. User (Developer) Manageable mini environments, or instance. Each developer instance shares the top level config (available modules and default config etc) A developer should have control over their apache and php version for each project. A developer might be able to change minor settings, ie magicquotes on for legacy code. Each project would determine its database provider in its code The idea is that it is one administrate-able server that I can control, and provide globally configured things like APC, Memcached, XDebug etc. Then by moving into subsets for each project, i can allow my users to quickly control their environments for various projects. Essentially I'm proposing the typical system of a developer running their own stack on their own machine, but centralised. In this way I'd hope to avoid problems like Cross OS code problems, database inconsistencies, slightly different installs producing bugs etc. I'm happy to manage this in custom builds from source, but if at all possible it would be great to have a large portion of it managed with some sort of package management. We typically use CentOS, so yum? Has anyone ever built anything like this before? Is there something turnkey that is similar to what I have described? Are there any useful guides I should be reading in order to build something like this?

• How to get child container reference in View Model

  - by niels-verkaart

  Hello, I´m trying to share a Data Service (Entity Manager) wrapped in a Repository from a ViewModel (called 'AVM') in Module A to a ViewModel (called 'BVM') in Module B, and I can't get this working. We use PRISM/Unity 2.0 This is my scenario: A user may open multiple Customer screens (composite view as mini shell) each with another customer (unit of work). We realize this using child containers. Each child container resolves it's own repository with its own Entity manager (the repository is a singleton within the child container). This is done in module A. The main shell has a main region manager, and each Customer screen with its childcontainer creates a scoped region. In each customer screen there is a View 'AV' (connected to ViewModel 'AVM') with a SubRegion (tab control) registered as 'SubRegion'. We create this with a 'Screen Factory' In Module B we have a Customer Orders in View 'BV' and ViewModel 'BVM'. In the constructor of Module B we get the main container by injection. In the initialize method we resolve the (main) region manager and register View 'BV' with it. In the constructor of View 'BV' a ViewModel 'BVM' is injected/created. Now this works, but the ViewModel 'BVM' cannot get the child container. It only get the main container. Is this doable, or do I have to do this another way? Thanks, Niels

• Looking for Hardware that will easily interface with my .NET code.

  - by SkippyFire

  I'm a .NET C# developer looking to do some hardware interfacing/programming. I just want something super simple to mess around with. I have done one of those basic stamp projects, but I want something with less electrical work. A self-contained piece of hardware would be fine. I'm not really looking to do embedded programming... but that would actually be pretty cool if something was capable of running .net code. I'm looking for something that would be easy to connect, hopefully via USB. Serial ports seems to be more hit or miss nowadays with laptops and netbooks. Something I can easily send data to, like a mini LCD, or series of LED's. Better yet would be something that provides feedback, like a temperature sensor. The best would be something more featured that I could talk to. I would be able to send data to it, and it would send back responses. Maybe something like a servo that could report it's position? Or maybe something that I could set parameters on? Any ideas? Thanks in advance!

• Any good tutorials or resources for learning how to design a scalable and "component" based game 'fr

  - by CodeJustin.com

  In short I'm creating a 2D mmorpg and unlike my last "mmo" I started developing I want to make sure that this one will scale well and work well when I want to add new in-game features or modify existing ones. With my last attempt with an avatar chat within the first few thousand lines of code and just getting basic features added into the game I seen my code quality lowering and my ability to add new features or modify old ones was getting lower too as I added more features in. It turned into one big mess that some how ran, lol. This time I really need to buckle down and find a design that will allow me to create a game framework that will be easy to add and remove features (aka things like playing mini-games within my world or a mail system or buddy list or a new public area with interactive items). I'm thinking that maybe a component based approach MIGHT be what I'm looking for but I'm really not sure. I have read documents on mmorpg design and 2d game engine architecture but nothing really explained a way of designing a game framework that will basically let me "plug-in" new features into the main game and use the resources of the main game without changing much within my 'main game code'. Hope someone understands what I mean, any help will is appreciated.

  I'm creating a dig like site with wordpress, TDO Mini forms and Vote it up where people who live in the city can log on, post their ideas of how to improve the city and have others vote. on the home page there are 2 columns. right is the TDO submit form. left are the "Most Wanted" items. the posts with the highest rating. I've found an impressive lack of information on this plugin. im not great with php but i can make do most of the time. I want to output the post title, post author, links for yes and no votes as well as have the titles in the left column list in most popular order. preferably id like the home pages to have only the top 5 or so highest rated posts. I cant find any way to output that information as i need. I was really hoping there was a simple way to call the highest rated post titles in the loop for the main page but there doesnt seem to be a way. Bout the only thing i've found is the DisplayVotes tag which isnt incredibly helpful. does anybody know how i can accomplish this, or can provide some expert advise? help would be immensely appreciated.

• How to install DBD::mysql on OS X Server 10.6?

  - by Zoran Simic

  Trying to install DBD::mysql on OS X Server 10.6 (mac mini server). But I'm missing the mysql headers apparently. Since mysql is already part of OS X Server 10.6, I would like to NOT install anything else (no fink or darwin ports installs), just whatever's needed to get DBD::mysql installed and working. Do you know how I could do that? Do I have to install the headers somewhere? And if so, where?

• Applescript from Mac App says "Expected end of line but found \U201c\"\U201d."

  - by Rasmus Styrk

  I am trying to perform a copy/paste for my to the the last active app, here's my code: NSString *appleScriptSource = [NSString stringWithFormat:@"\ntell application \"%@\" to activate\ntell application \"System Events\" to tell process \"%@\"\nkeystroke \"v\" using command down\nend tell", [lastApp localizedName], [lastApp localizedName]]; NSDictionary *error; NSAppleScript *aScript = [[NSAppleScript alloc] initWithSource:appleScriptSource]; NSAppleEventDescriptor *aDescriptor = [aScript executeAndReturnError:&error]; The problem is that on some computers it works just fine, but on others it fails. My error output from error that is returned by executeAndReturnError is: 2012-06-13 17:43:19.875 Mini Translator[1206:303] (null) (error: { NSAppleScriptErrorBriefMessage = "Expected end of line but found \U201c\"\U201d."; NSAppleScriptErrorMessage = "Expected end of line but found \U201c\"\U201d."; NSAppleScriptErrorNumber = "-2741"; NSAppleScriptErrorRange = "NSRange: {95, 1}"; }) I can't seem to figure out what it means or why it happens. We tried copying the generated apple-script code into the Apple Script editor, and here it works just fine. My App is sandboxed - i have added the bundle identifiers for the key "com.apple.security.temporary-exception.apple-events" for the apps i want to support. Any suggestions?

• Toggle Blind Effect

  - by flipflopmedia

  Is there a way to alter this script to be used as the blind effect. // Andy Langton's show/hide/mini-accordion - updated 23/11/2009 // Latest version @ http://andylangton.co.uk/jquery-show-hide // this tells jquery to run the function below once the DOM is ready $(document).ready(function() { // choose text for the show/hide link - can contain HTML (e.g. an image) var showText=''; var hideText=''; // initialise the visibility check var is_visible = false; // append show/hide links to the element directly preceding the element with a class of "toggle" $('.toggle').prev().append(' '+showText+''); // hide all of the elements with a class of 'toggle' $('.toggle').hide(); // capture clicks on the toggle links $('a.toggleLink').click(function() { // switch visibility is_visible = !is_visible; // toggle the display - uncomment the next line for a basic "accordion" style //$('.toggle').hide();$('a.toggleLink').html(showText); $(this).parent().next('.toggle').toggle('slow'); // return false so any link destination is not followed return false; }); }); FYI- Where it says: var showText=''; var hideText=''; It was originally: var showText='Show'; var hideText='Hide'; I deleted the Show/Hide Text because I am applying the link to different areas of text. I like the Blind effect, vs. this Toggle effect, and need to know how to apply it, if possible. I cannot find a basic Blind effect script that allows the use of applying the link to ANY text, vs. a button or static text. Thanks! Hope you can help! Tracy

• django url user id versus userprofile id problem

  - by dana

  hello there, i have a mini comunity where each user can search and find another user profile. Userprofile is a class model, indexed differently compared to user model class (user id is not equal to userprofile id) But i cannot see a user profile by typing in the url the corresponding id. I only see the profile of the currently logged in user. Why is that? I'd also want to have in my url the username (a primary key of the user table also) and NOT the id (a number). The guilty part of the code is: what can i replace that request.user with so that it wil actually display the user i searched for, and not the currently logged in? def profile_view(request, id): u = UserProfile.objects.get(pk=id) cv = UserProfile.objects.filter(created_by = request.user) blog = New.objects.filter(created_by = request.user) return render_to_response('profile/publicProfile.html', { 'u':u, 'cv':cv, 'blog':blog, }, context_instance=RequestContext(request)) in urls (of the accounts app): url(r'^profile_view/(?P<id>\d+)/$', profile_view, name='profile_view'), and in template: <h3>Recent Entries:</h3> {% load pagination_tags %} {% autopaginate list 10 %} {% paginate %} {% for object in list %} <li>{{ object.post }} <br /> Voted: {{ vote.count }} times.<br /> {% for reply in object.reply_set.all %} {{ reply.reply }} <br /> {% endfor %} <a href=''> {{ object.created_by }}</a> <br /> {{object.date}} <br /> <a href = "/vote/save_vote/{{object.id}}/">Vote this</a> <a href="/replies/save_reply/{{object.id}}/">Comment</a> </li> {% endfor %} thanks in advance!

• lightweight webserver to integrate on client end.

  - by Gopal

  Hi ,... I need to create a python module that will be installed on end-user machines. One of the scripts in that module should be able to receive http POSTS (usually with some JSON formatted data in the body) and then pass on that data to an appropriate python script. I can think of two ways to do this: a) Open a listening server socket on port 80, wait for that http request to come in, parse it and then pass that data to another python script depending on the url that arrived. This method will not require the end-user to install a webserver. End user only has to install the python module. b) Have a mini-webserver installed along with the python module. The webserver will do the same job as [a] via CGI without me requiring to write the CGI functionality. But then the user will have to install the web-server (ie., the hassle of yet another install). Would like to avoid that if possible. IF [b] is the easier option, what is the smallest simplest webserver there is (preferably one that can be packaged as part of the python module itself so that it does not have to be separately installed). Must be opensource of course. regards Gopal

• Why won't VS2010 RC use my existing types when I add a service reference?

  - by Johan Driessen

  I have a huge problem getting services references in VS2010 RC to use existing assemblies. Even though I have a class library with all the data contracts (classes marked with DataContract and properties with DataMember) that is shared between the service project and the consuming project (which is a class library), when I add a service reference, the data contracts are regenerated withing the service reference instead of using the existing types. When I was using VS2010 beta 2, this worked fine, and I have existing service references using the very same data contracts. But if I add a new service reference, or even update an old one, it won't use the existing types anymore. I have made a mini-test-solution, with one service, one data contract type and one console app as a consumer (all in the same solution), and there it seems to work, but that's no great comfort to me. Is there any way to see why it can't use the existing types? Edit to clearify. It works to generate the proxy classes with svcutil.exe, and point to the data contracts dll, like this: svcutil.exe http://localhost/MyService.svc /reference:[Path To DataContracts]\DataContracts.dll /n:*,MyProject.MyServiceReference /ct:System.Collections.Generic.List`1 The question is, what possible reason could there be for Visual Studio to generate its own datacontracts instead of using the existing ones even though the "reuse" checkbox is checked and the datacontracts assembly is referenced.

• Email Collector / Implementation

  - by Tian

  I am implementing a simple RoR webpage that collect emails from visitors and store them as objects. I'm using it as a mini-project to try RoR and BDD. I can think of 3 features for Cucumber: 1. User submits a valid email address 2. User submits an existing email address 3. User submits an invalid email My question is, for scenarios 2 and 3, is it better to handle this via the controller? or as methods in a class? Perhaps something that throws errors if an instance is instantiated in sceanrio 2 or 3? Implementation is below, love to hear some code reviews in addition to answers to questions above. Thanks! MODEL: class Contact < ActiveRecord::Base attr_accessor :email end VIEW: <h1>Welcome To My Experiment</h1> <p>Find me in app/views/welcome/index.html.erb</p> <%= flash[:notice] %> <% form_for @contact, :url => {:action => "index"} do |f| %> <%= f.label :email %><br /> <%= f.text_field :email %> <%= submit_tag 'Submit' %> <% end %> CONTROLLER: class WelcomeController < ApplicationController def index @contact = Contact.new unless params[:contact].nil? @contact = Contact.create!(params[:contact]) flash[:notice] = "Thank you for your interest, please check your mailbox for confirmation" end end end

• Redirect Desktop Internal Pages to Correct Mobile Internal Pages with Htaccess

  - by Luis Alejandro Ramrez Gallardo

  I have built a Mobile site in a sub-domain. I have successfully implemented the redirect 302 from: www.domain.com to m.domain.com in htaccess. What I'm looking to achieve now it to redirect users from: www.domain.com/internal-page/ > 302 > m.domain.com/internal-page.html Notice that URL name for desktop and mobile is not the same. The code I'm using looks like this: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress # Mobile Redirect # Verify Desktop Version Parameter RewriteCond %{QUERY_STRING} (^|&)ViewFullSite=true(&|$) # Set cookie and expiration RewriteRule ^ - [CO=mredir:0:www.domain.com:60] # Prevent looping RewriteCond %{HTTP_HOST} !^m.domain.com$ # Define Mobile agents RewriteCond %{HTTP_ACCEPT} "text\/vnd\.wap\.wml|application\/vnd\.wap\.xhtml\+xml" [NC,OR] RewriteCond %{HTTP_USER_AGENT} "sony|symbian|nokia|samsung|mobile|windows ce|epoc|opera" [NC,OR] RewriteCond %{HTTP_USER_AGENT} "mini|nitro|j2me|midp-|cldc-|netfront|mot|up\.browser|up\.link|audiovox"[NC,OR] RewriteCond %{HTTP_USER_AGENT} "blackberry|ericsson,|panasonic|philips|sanyo|sharp|sie-"[NC,OR] RewriteCond %{HTTP_USER_AGENT} "portalmmm|blazer|avantgo|danger|palm|series60|palmsource|pocketpc"[NC,OR] RewriteCond %{HTTP_USER_AGENT} "smartphone|rover|ipaq|au-mic,|alcatel|ericy|vodafone\/|wap1\.|wap2\.|iPhone|android"[NC] # Verify if not already in Mobile site RewriteCond %{HTTP_HOST} !^m\. # We need to read and write at the same time to set cookie RewriteCond %{QUERY_STRING} !(^|&)ViewFullSite=true(&|$) # Verify that we previously haven't set the cookie RewriteCond %{HTTP_COOKIE} !^.*mredir=0.*$ [NC] # Now redirect the users to the Mobile Homepage RewriteRule ^$ http://m.domain.com [R] RewriteRule $/internal-page/ http://m.domain.com/internal-page.html [R,L]
