  • Where is PostSharp.Public 1.5 DLL ?

    - by jfneis
    Fellows, I'm going crazy with looks like a really stupid problem. I'm trying to build a simple example using PostSharp as a log AOP utility. I've not installed PostSharp, and I don't want to, I want to reference the necessaries DLLs, change my .csproj and see everything working. Change the project and add references was kind of easy, byt just after adding the LogAttribute to a method I got two errors: Error 1 'Log4PostSharp.LogAttribute' is not an attribute class C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 17 10 LogWithPostsharpCmd Error 2 The type 'PostSharp.Extensibility.MulticastAttribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'PostSharp.Public, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b13fd38b8f9c99d7'. C:\Dev\LogWithPostsharp\LogWithPostsharpCmd\Program.cs 18 22 LogWithPostsharpCmd The first error really looks like consequence of the second, but here is the deal: the PostSharp.Public.* simply doesn't exist in the downloaded .zip. Is there something that I'm not getting? Thank you in advance. Filipe

  • issues with horizontal scrolling using jQuery.ScrollTo / jQuery.SerialScroll

    - by kapil.israni
    Hi, I am trying to develop auto horizontal scrolling for our website using - jQuery.ScrollTo / jQuery.SerialScroll. I am not sure if this is the best jquery library to do that, but if there's something better, please let me know. Here's the behavior that I want, check out foursquare's "Recent Activity" list. The data that will refresh will come from a ajax request that I make every few seconds using window.setInterval. I am not really a CSS/java script guy so I havent been able to figure out jQuery.SerialScroll. Here's the website - look at the "Live job Feeds" list. Currently the list does refresh the data coming from the ajax call, but I dont see the effect, the animation, in fact I dont even think serialScroll is being used. Right now I am doing a - $('#feed-ticker').prepend(content) to pre-append the newly arrived data. You can do a view source to look at the current code. Any help would be really appreciated. Thanks.

  • best way to save data in ipod touch/iphone objective-c

    - by Leonardo
    Hi all, I am writing a very simple application, for iphone. Unfortunately I am really a newbie. What I am trying to do is to save data at the end of a user experience. These data are really simple, only string or int, or some array. Later I want to be able to retrieve that data, therefore I also need an event id (I suppose). Could you please point out the best way, api or technology to achieve that, xml, plain text, serialization... ? many thanks Leonardo

  • Team Foundation Server Setup/Access

    - by Angel Brighteyes
    What I need: A TFS 2010 Setup that allows 2 application developers to access the TFS from remote locations. How it is setup: Server 2008 Standard 2g Ram 300g HD space SharePoint Server 2007, using SQL Server 2005 SQL Server 2008 Standard Team Foundation Server 2010 IIS 7 Sharepoint Bindings: TFS.DynAccount.Me:80; TFS:80 TFS Bindings: TFS.DynAccount.Me:8080; TFS:8080 Using DynDNS service to account for the dynamic ip address being used, this is a requirement for the moment until I can get a better isp package. Access using Local Accounts Server is not setup on a domain, or as a domain. Consequently I did not setup AD services. Problem: When logged into TFS using my credentials TFS\AdminUser through the DynDNS account TFS.DynAccount.Me I recieve the 'Red X of Death' on the Documents and Reports folder. When logged into the TFS through the local peer to peer network using the same credentials TFS\AdminUser I do not receive the 'Red X of Death' problem. Further Troubleshooting: When users 'Right Click' the 'TeamProject1' Click 'Show Project Portal' it tries to take them to http://TFS:8080 instead of http://TFS.DynAccount.Me:8080, which doing further research I am assuming that it is because team foundation server was setup with a local name of TFS instead of 'TFS.DynAccount.Me' as specified here in Visual Studio Magazines: The Red X of Death. Users can Access the Team Portal for SharePoint via http://TFS.DynAccount.Me/TeamCollection/TeamProject so it is not like we are dead in the water or anything. However, as most employees/staff are prone to do, they have expressed a great distaste for having to do it this way and just be patient until the current project is finished since we are under a very strict deadline. Is there a way to set this up differently, or change some settings someplace, reinstall it, point a CName record for our domain website to the DynAccount (e.g. TFS.OurDomain.com points to TFS.DynAccount.Me, which consequently does allow access to the http site without issues), or something. I really don't feel like after all the time and effort I have spent into, first the cost, second the bloody install, third learning SharePoint well enough, fourth the hours into days spent on this, fifth more troubleshooting, sixth employee headaches to just let it lay where it is at. I figure in my spare/off time I would keep trying to get this to work. So I really appreciate any help any one can give me. I know this is probably something really stupid simple that I will 'Face Palm' over, but at the moment the stress and frustration just has me beat. Thank you again, this community has always been a great help.

  • REST api ambiguity and WADL

    - by JDonner
    I have a REST api that's ambiguous, something like (this isn't the specific problem, just gives an idea of the ambiguity): /toplevel/${customer_number}/some_command/more stuff /toplevel/${customer_number}/${some_product_name_anything_goes}/more stuff We've been getting away with it because our .htaccess file lists the more specific 'command' form before the general ${product_name} version, and the first match wins. Now though, we're writing a WADL, and, as you might expect, we're having trouble with our chosen tool consuming the WADL, because the API is ambiguous. My questions are: a) Does the WADL spec speak to whether they can validly represent ambiguous APIs? b) Tool support - in your experience, do tools choke on ambiguous WADLs? (if ambi. WADLs are allowed then those are weak tools but, you'd want to be on the safe side) c) Just any experience with ambiguous REST apis, most especially wrt WADLs, really. For the curious, here's the latest spec: As far as I can tell it doesn't specifically address this, I guess it really comes down to how tools handle it. Thanks.

  • Freeware Programmer Calculator

    - by AdamC
    There have been lots of times in the past where a good programmer-oriented calculator would've saved me a lot of time. Lately, I've been doing quite a lot of bit manipulation, and having to do build/run to debug my calculations feels really slow. I've looked for something like this in the past, but found nothing that worked very well. The only thing that comes close is this one from AnalogX, but I can't get it to work or really do anything on my vista box which is where I'm doing most of my work at the moment. (btw - please send comments about my vista usage here;). Anyway, I'm looking for something for simple calculations using a C-like syntax with support for proper precenedce, operators, etc. Bonus points for cross-platform. The python interpreter was a great idea and is totally cross-platform. For windows only SpeQ is amazing. Thanks for the suggestions.

  • How to throttle login attemps in Java webapp?

    - by Jörn Zaefferer
    I want to implement an efficient mechanism to throttle login attemps in my Java web application, to prevent brute-force attacks on user accounts. Jeff explained the why, but not the how. Simon Willison showed an implementation in Python for Django: That doesn't really help me along as I can't use memcached nor Django. Porting his ideas from scratch doesn't seem like a great either - I don't want to reinvent the wheel. I found one Java implementation, though it seems rather naiive: Instead of a LRU cache, it just clears all entries after 15 minutes. EHCache could be an alternative for memcached, but I don't have any experience with it and don't really want to intoduce yet another technology if there are better alternatives for this task. So, whats a good way to implement login throttling in Java?

  • How to Redirect Visual Studio F12 Shortcut Key to Object Browser in C# Project

    - by AMissico
    For C# projects, I would like to have the F12 "Go to Definition" shortcut key to open the Object Browser and select the type under the cursor position. This is the behavior for VB.NET projects, which I really like. I think the Object Browser is more helpful than IntelliSense in some cases. I really do not need a text representation of the metadata. How do I duplicate the F12 / "Go to Definition" functionality in a C# project? Is there a different shortcut key for C#? I am not talking about the Alt+Ctrl+J shortcut key that displays the Object Browser.

  • Rename "Event" object in jQuery FullCalendar plug-in

    - by Jeff
    GREAT PLUGIN!!! BUT... choice of word "Event" to mean a "calendar entry" was particularly unfortunate This is a wonderfully well-written plug in, and I've really impressed people here at work with what this thing can do. The documentation is astonishingly thorough and clear. Congratulations to Adam! HOWEVER, this plug-in refers to entries in the calendar as "Events" -- this has caused a lot of confusion in my development team's conversations, because when we use the word "Event" we think of things like onmouseover, click, etc. We would really prefer a term like CalendarEvent or CalendarEntry. I am not all that experienced with jQuery yet, so am wondering if there is a simple way to alias one of those terms to this plug-in's Event/Events object? (I know we could recode the plug-in directly, but our code will then break when we download an update.) Thanks!

  • Using the Specification Pattern

    - by Kane
    Like any design pattern the Specification Pattern is a great concept but susceptible to overuse by an eager architect/developer. I am about to commence development on a new application (.NET & C#) and really like the concept of the Specification Pattern and am keen to make full use of it. However before I go in all guns blazing I would be really interested in knowing if anyone could share the pain points that experienced when use the Specification Pattern in developing an application. Ideally I'm looking to see if others have had issues in Writing unit tests against the specification pattern Deciding which layer the specifications should live in (Repository, Service, Domain, etc) Using it everywhere when a simple if statement would have done the job etc? Thanks in advance

  • Why don't Direct2D and DirectWrite use traditional COM objects?

    - by David Brown
    I'm toying with a little 2D game engine in C# and decided to use Direct2D and DirectWrite for rendering. I know there's the Windows API Code Pack and SlimDX, but I'd really like to dig in and write an interface from scratch. I'm trying to do it without Managed C++, but Direct2D and DirectWrite don't appear to use traditional COM objects. They define interfaces that derive from IUnknown, but there appears to be no way to actually use them from C# with COM interop. There are IIDs in d2d1.h, but no CLSID. Of course, I'm really new to COM interop, so perhaps I'm just missing something. Can someone shed some light on this situation?

  • Storing user info in Session using an Object vs. normal variables

    - by justinl
    I'm in the process of implementing a user authentication system for my website. I'm using an open source library that maintains user information by creating a User object and storing that object inside my php SESSION variable. Is this the best way to store and access that information? I find it a bit of a hassle to access the user variables because I have to create an object to access them first: $userObj = $_SESSION['userObject']; $userObj->userId; instead of just accessing the user id like this how I would usually store the user ID: $_SESSION['userId']; Is there an advantage to storing a bunch of user data as an object instead of just storing them as individual SESSION variables? ps - The library also seems to store a handful of variables inside the user object (id, username, date joined, email, last user db query) but I really don't care to have all that information stored in my session. I only really want to keep the user id and username.

  • Using Nearest Neighbour Algorithm for image pattern recognition

    - by user293895
    So I want to be able to recognise patterns in images (such as a number 4), I have been reading about different algorithms and I would really like to use the Nearest Neighbour algorithm, it looks simple and I do understand it based on this tutorial: http://people.revoledu.com/kardi/tutorial/KNN/KNN_Numerical-example.html Problem is, although I understand how to use it to fill in missing data sets, I don't understand how I could use it as a pattern recognition tool to aim in Image Shape Recognition. Could someone please shed some light as to how this algorithm could work for pattern recognition? I have seen tutorials using OpenCV, however I don't really want to use this library as I have the ability to do the pre-processing myself, and it seems silly that I would implement this library just for what should be a simple nearest neighbour algorithm.

  • PHP and SwfUpload

    - by balanza
    Hi, I'm trying to implement SwfUpload in my web page, and I'm using php to save files on server. As is the first time I use this component, I choose to run the algoritm is suggested from the SwfUpload team (http://swfupload.org/forum/generaldiscussion/214): I've put it in a file and I've said the control to use it as code file. It didn't work, as I'm asking help, but what really drives me crazy is that i really don't know how to debug that stuff! The request to the file is encapsulated into the flash object, and i can't get any feedback from it if something goes wrong. Anyone is more experienced than me about this control? Thanks

  • Python serialize lexical closures?

    - by dsimcha
    Is there a way to serialize a lexical closure in Python using the standard library? pickle and marshal appear not to work with lexical closures. I don't really care about the details of binary vs. string serialization, etc., it just has to work. For example: def foo(bar, baz) : def closure(waldo) : return baz * waldo return closure I'd like to just be able to dump instances of closure to a file and read them back. Edit: One relatively obvious way that this could be solved is with some reflection hacks to convert lexical closures into class objects and vice-versa. One could then convert to classes, serialize, unserialize, convert back to closures. Heck, given that Python is duck typed, if you overloaded the function call operator of the class to make it look like a function, you wouldn't even really need to convert it back to a closure and the code using it wouldn't know the difference. If any Python reflection API gurus are out there, please speak up.

  • chat application: pubsubhubbub vs xmpp

    - by sofia
    I'm unsure on the best stack to build a chat application. Currently I'm thinking of two main options: facebook tornado cons: does not use the main chat protocol xmpp but pubsubhubbub pros: i really like its simplicity for development (webserver + webframework); pubsubhubbub also seems simpler as a protocol than xmpp; and i know python xmpp + bosch, punjab, ejabberd cons: don't know erlang; overall seems a bit harder to develop pros: uses xmpp protocol The chat app will need to have the following: Private messages Public rooms Private rooms Chat history for rooms (not forever, just the last n messages) html embedding url to chat room Both options seem scalable so that's not really my worry (we're thinking of running the app in amazon's ec2 as well). I know there's a project that builds a xmpp server using tornado but it's not ready for production use and our deadline isn't that big. Basically my main worry is ease of development vs somehow regretting later using pubsubhubbub to develop a chat app but I read somewhere that PubSubHubbub might eventually replace XMPP as REST replaced SOAP - so what do you think?

  • Split NSData objects into other NSData objects with a given size

    - by Cedric Vandendriessche
    I'm having an NSData object of approximately 1000kb big. Now I want to transfer this via bluetooth. This would be better if I have let's say 10 objects of 100kb. It comes to mind that I should use the -subdataWithRange: method of NSData. I haven't really worked with NSRange. Well I know how it works, but then to read from a given location with the length: 'to end of file'... I've no idea how to do that. Some code on how to split this into multiple 100kb NSData objects would really help me out here. (it probably involves the length method to see how many objects should be made..?) Thank you in advance.

  • Mysql Sub Select Query Optimization

    - by Matt
    I'm running a query daily to compile stats - but it seems really inefficient. This is the Query: SELECT a.id, tstamp, label_id, (SELECT author_id FROM b WHERE b.tid = a.id ORDER BY b.tstamp DESC LIMIT 1) AS author_id FROM a, b WHERE (status = '2' OR status = '3') AND category != 6 AND a.id = b.tid AND (b.type = 'C' OR b.type = 'R') AND a.tstamp1 BETWEEN {$timestamp_start} AND {$timestamp_end} ORDER BY b.tstamp DESC LIMIT 500 This query seems to run really slow. Apologies for the crap naming - I've been asked to not reveal the actual table names. The reason there is a sub select is because the outer select gets one row from the table a and it gets a row from table b. But also need to know the latest author_id from table b as well, so I run a subselect to return that one. I don't want to run another select inside a php loop - as that is also inefficient. It works correctly - I just need to find a much faster way of getting this data set.

  • importing pywiiuse to test out

    - by Patrick Burton
    This is probably a simple problem. But I downloaded the pywiiuse library from here and I also downloaded the examples. However when I try to run one of the examples I end up with import issues. I'm not certain I have everything configured properly to run. One error I receive when trying to run example.py: Press 1&2 Traceback (most recent call last): File "example.py", line 73, in <module> wiimotes = wiiuse.init(nmotes) File "/home/thed0ctor/Descargas/wiiuse-0.12/wiiuse/__init__.py", line 309, in init dll = ctypes.cdll.LoadLibrary('libwiiuse.so') File "/usr/lib/python2.7/ctypes/__init__.py", line 431, in LoadLibrary return self._dlltype(name) File "/usr/lib/python2.7/ctypes/__init__.py", line 353, in __init__ self._handle = _dlopen(self._name, mode) OSError: libwiiuse.so: cannot open shared object file: No such file or directory I'm really just starting out with this library and don't really see any documentation on how to configure pywiiuse so any help is much appreciated.

  • Algorithm and data structure learning resources for dynamic programming

    - by Pranav
    Im learning dynamic programming now, and while I know the theory well, designing DP algorithms for new problems is still difficult. This is what i would really like now- A book or a website, which poses a problem which can be solved by dynamic programming. Also there is the solution with an explanation available, which i would like to see if i cant solve the problem even after butting my head at it for a few hours. Is there some resource that provides this sort of a thing for several categories of algorithms- like graph algorithms, dynamic programming, etc? P.S. I considered Topcoder, but the solutions there are not really appropriate for learning to implement efficient solutions.

  • Java Concurrency: CAS vs Locking

    - by Hugo Walker
    Im currently reading the Book Java Concurrency in Practice. In the Chapter 15 they are speaking about the Nonblocking algorithms and the compare-and-swap (CAS) Method. It is written that the CAS perform much better than the Locking Methods. I want to ask the people which already worked with both of this concepts and would like to hear when you are preferring which of these concept? Is it really so much faster? Personally for me the usage of Locks is much clearer and easier to understand and maybe even better to maintain. (Please correct me if I am wrong). Should we really focus creating our concurrent code related on CAS than Locks to get a better performance boost or is sustainability a higher thing? I know there is maybe not a strict rule, when to use what. But I just would like to hear some opinions, experiences with the new concept of CAS.

  • "My account" or "Your account" labels

    - by Ferdy
    I have somewhat of a strange question that is not really technical, but I do hope to collect meaningful advice. I'm building a large web application, basically a photo sharing community site. As part of this site, logged-in users can go to their profile, from which they can see their own things (images, comments, votes) as well as edit their details and preferences. Users can also see profiles of others users (their images, comments, votes), but of course not edit their details. The question I have is simple but it keeps bothering me: What to call the personal links and content of a user? Should they be named "Your": Your images Your profile ... ...or "My": My images My profile ...or perhaps named, even if you're logged in: Fledder's images Fledder's profile As unimportant as it may sounds, I'm really looking for advice in this area. I'm particularly interested in any standards, why an option is preferred, and in which contexts it is preferred.

  • What's the best way to explain parsing to a new programmer?

    - by Daisetsu
    I am a college student getting my Computer Science degree. A lot of my fellow students really haven't done a lot of programming. They've done their class assignments, but let's be honest here those questions don't really teach you how to program. I have had several other students ask me questions about how to parse things, and I'm never quite sure how to explain it to them. Is it best to start just going line by line looking for substrings, or just give them the more complicated lecture about using proper lexical analysis, etc. to create tokens, use BNF, and all of that other stuff? They never quite understand it when I try to explain it. What's the best approach to explain this without confusing them or discouraging them from actually trying.

  • Visual Web Developer 2008 Express and XHTML 1.1 (not applying)

    - by Mike Valeriano
    Hello. I may be missing something since I'm not used to work with IDEs for web development, so please understand if I'm doing something stupid. I've picked a copy of Beginning ASP.NET 3.5 in C# and VB to try and learn this thing quickly. I'm no HTML guru, but I know something about the DTDs and I want to either use XHTML 1.0 Strict or XHTML 1.1 while learning the ins and outs of ASP.NET. Following the book (just started actually), I'm not having any trouble understanding the concepts, since I have a C# background, but what I don't understand is how VWD goes about applying the schema you select for validation. The book explains that the drop-down list on the toolbar is enough to set this, so that's what I did: I've selected XHTML 1.1 (since there is no 1.0 strict option, what I find really odd) and then started the project. The thing is that the code generated automatically for the Default page had the XHTML 1.0 transitional DTD. Every other page added had the same DTD, even though XHTML 1.1 is still the selected schema in the drop-down list. I decided to test it out and there it was: inserting some text in the design view and then applying a bold formatting just inserted < b tags on the code. Changing color does add a span tag with added CSS though. What I want to know is: if I want strict XHTML (or 1.1) should I just code it manually? Or is there a "fix" for this problem (having a schema selected but not applied by the IDE)? Am I missing something really easy and dumb? I have no problem with coding it manually - I actually prefer doing that. The thing is that I really wanna try this WYSIWYG approach for once, since some developers swear by it. Plus I don't know yet if I'll need special tags for ASP.NET, so I think having them inserted automatically should be the best practice. I couldn't find any similar problems around (MSDN, Google, here), and as far as the book goes (up to the point I've read), this is the expected VWD behavior, which I find suspect at least. Sorry for the long text (and poor English - not my primary language). Thanks in advance for any help/tips.

  • Polygon triangulation

    - by Saurabh
    Hey, I am working on nesting of sheet metal parts and am implementing Minkowski Sums to find No Fit Polygons for nesting. The problem is I can give only convex sets as input to the code which calculates Minkowski sums for me. Hence I need to break a concave polygon, with holes into Convex sets. I am open to triangulation also, but I am looking for a working code on VC++ (6.0). I am slightly running short on time as my whole code is ready and just waiting for input in the form of convex sets. I would really appreciate if somebody with prior experience can help me in this. I have gone through other posts but did not find anything matching to this. I am a student of mechanical engineering and really dun have much idea about computer languages. All I can handle is compiling a code on VC++ and incorporate it with my existing code. Looking forward to responses!! Thanks Warm regards Saurabh India
