Is there a way to use sharepoint as the back-end versioning and storage for my custom document manag

I want to build a custom document management web application that ties in with sharepoint for the actual document versioning and storage. I'm hoping for something like a sharepoint widget that I can plug into my web application that would allow me to tie in with sharepoint and download documents, make edits to them, and upload them back to sharepoint, with sharepoint handling all of the versioning and storage. If WSS is the answer to this, are there licensing issues that I need to consider? Thanks.

Free downloadable products in Magento

- by Aaron Newton

Hello Magento boffins. I am using Magento to build an eBooks site. For the release, we plan to have a number of free downloadable books. We were hoping that it would be possible to use the normal Magento 'catalog' functionality to add categories with products underneath. However, since these are free downloadable products, it doesn't really make sense to send users through the checkout when they try to download. Does anyone know of a way to create a free downloadable product which bypasses the checkout altogether? I have noticed that there is a 'free sample' option for downloadable products, but I would prefer not to use this if I can as I plan to use this field for its intended purpose when I add paid products.

Will Apple's new "originally written in" clause affect your decision to target the iPhone?

- by Michael Aaron Safyan

So, you've probably heard about Apple's change to its agreement to prohibit source-to-source translation, thereby blocking translation from Flash (in CS5) and also from Android (via XMLVM). You may also have read about a response by a well-known Adobe developer, and calls to boycott development for the iPhone. Given that this audience is a better representative of the developer community than those who post comments on the NYT, Digg, and other news sites, I was wondering what your opinions were about this decision. Will any of you switch to Android from the iPhone or avoid development on the iPhone as a result of this? Since this is fairly subjective, I am making this a community wiki. Also, please, keep things civil.

How can I get the data from an ajax request to appear inside a div?

- by Aaron Brokmeier

I am unable to get the data from my ajax request to appear inside <div class="l_p_i_c_w"></div>. What am I doing wrong? I know the function inside my_file.php works, because if I refresh the page, then the data shows up where it should. jQuery: $.ajax({ type: "POST", url: "my_file.php", dataType: 'html', success: function(data){ $('div#myID div.l_p_c div.l_p_i_c_w').prepend(data); } }); HTML: <div class="l_p_w" id="myID"> <div class="l_p_c"> <div class="l_p_i_c_w">  </div> </div> </div> CSS: .l_p_w { width:740px; min-height:250px; margin:0 auto; position:relative; margin-bottom:10px; } .l_p_c { position:absolute; bottom:10px; right:10px; width:370px; top:60px; } .l_p_i_c_w { position:absolute; left:5px; top:5px; bottom:5px; right:5px; overflow-x:hidden; overflow-y:auto; }

Creating a customized video using Flash and XML

- by Aaron Ladage

The problem: I have to create a Flash video (in CS3) that will query a MySQL database and display that data at certain points in the video. The bigger problem: I'm not a Flash/ActionScript developer, so this is all very foreign to me! I've divided this project into two parts: a.) dynamically generate an XML feed from the data using PHP (using an ID number passed in the URL's query string), and b.) be able to work with it in Flash. I've got the first part working, but am pretty lost in Flash. I can parse the XML, but I'm not sure how to set the data up as variables and attach it to a video's cue points. Can anyone point me in the direction of a good tutorial or offer some advice?

Is there an algorithm to securely split a message into x parts requiring at least y parts to reassem

- by Aaron

Is there an algorithm to securely split a message into x parts requiring at least y parts to reassemble? Obviously, y <= x. An example: Say that I have a secret message that I only want to be read in the event of my death. As a way to ensure this, I give a fraction of the message to ten friends. Now, I can't guaranty that all my friends will be able to put their messages together to recover the original. So, I construct each message fraction in such a way so as to only require any 5 friends to put their parts together to reconstruct the whole. However, owning less than 5 parts will not give anything away about the message, except possibly the length. My question is, is this possible? What algorithms might I look at to accomplish this? Clarification edit: The important part of this is the cryptographic strength. An attacker should not be able to recover the message, either in whole or in part with less than y parts.

PyML 0.7.2 - How to prevent accuracy from dropping after stroing/loading a classifier?

- by Michael Aaron Safyan

This is a followup from "Save PyML.classifiers.multi.OneAgainstRest(SVM()) object?". The solution to that question was close, but not quite right, (the SparseDataSet is broken, so attempting to save/load with that dataset container type will fail, no matter what. Also, PyML is inconsistent in terms of whether labels should be numbers or strings... it turns out that the oneAgainstRest function is actually not good enough, because the labels need to be strings and simultaneously convertible to floats, because there are places where it is assumed to be a string and elsewhere converted to float) and so after a great deal of hacking and such I was finally able to figure out a way to save and load my multi-class classifier without it blowing up with an error.... however, although it is no longer giving me an error message, it is still not quite right as the accuracy of the classifier drops significantly when it is saved and then reloaded (so I'm still missing a piece of the puzzle). I am currently using the following custom mutli-class classifier for training, saving, and loading: class SVM(object): def __init__(self,features_or_filename,labels=None,kernel=None): if isinstance(features_or_filename,str): filename=features_or_filename; if labels!=None: raise ValueError,"Labels must be None if loading from a file."; with open(os.path.join(filename,"uniquelabels.list"),"rb") as uniquelabelsfile: self.uniquelabels=sorted(list(set(pickle.load(uniquelabelsfile)))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; self.classifiers=[]; for classidx, classname in enumerate(self.uniquelabels): self.classifiers.append(PyML.classifiers.svm.loadSVM(os.path.join(filename,str(classname)+".pyml.svm"),datasetClass = PyML.VectorDataSet)); else: features=features_or_filename; if labels==None: raise ValueError,"Labels must not be None when training."; self.uniquelabels=sorted(list(set(labels))); self.labeltoindex={}; for idx,label in enumerate(self.uniquelabels): self.labeltoindex[label]=idx; points = [[float(xij) for xij in xi] for xi in features]; self.classifiers=[PyML.SVM(kernel) for label in self.uniquelabels]; for i in xrange(len(self.uniquelabels)): currentlabel=self.uniquelabels[i]; currentlabels=['+1' if k==currentlabel else '-1' for k in labels]; currentdataset=PyML.VectorDataSet(points,L=currentlabels,positiveClass='+1'); self.classifiers[i].train(currentdataset,saveSpace=False); def accuracy(self,pts,labels): logger=logging.getLogger("ml"); correct=0; total=0; classindexes=[self.labeltoindex[label] for label in labels]; h=self.hypotheses(pts); for idx in xrange(len(pts)): if h[idx]==classindexes[idx]: logger.info("RIGHT: Actual \"%s\" == Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])); correct+=1; else: logger.info("WRONG: Actual \"%s\" != Predicted \"%s\"" %(self.uniquelabels[ classindexes[idx] ], self.uniquelabels[ h[idx] ])) total+=1; return float(correct)/float(total); def prediction(self,pt): h=self.hypothesis(pt); if h!=None: return self.uniquelabels[h]; return h; def predictions(self,pts): h=self.hypotheses(self,pts); return [self.uniquelabels[x] if x!=None else None for x in h]; def hypothesis(self,pt): bestvalue=None; bestclass=None; dataset=PyML.VectorDataSet([pt]); for classidx, classifier in enumerate(self.classifiers): val=classifier.decisionFunc(dataset,0); if (bestvalue==None) or (val>bestvalue): bestvalue=val; bestclass=classidx; return bestclass; def hypotheses(self,pts): bestvalues=[None for pt in pts]; bestclasses=[None for pt in pts]; dataset=PyML.VectorDataSet(pts); for classidx, classifier in enumerate(self.classifiers): for ptidx in xrange(len(pts)): val=classifier.decisionFunc(dataset,ptidx); if (bestvalues[ptidx]==None) or (val>bestvalues[ptidx]): bestvalues[ptidx]=val; bestclasses[ptidx]=classidx; return bestclasses; def save(self,filename): if not os.path.exists(filename): os.makedirs(filename); with open(os.path.join(filename,"uniquelabels.list"),"wb") as uniquelabelsfile: pickle.dump(self.uniquelabels,uniquelabelsfile,pickle.HIGHEST_PROTOCOL); for classidx, classname in enumerate(self.uniquelabels): self.classifiers[classidx].save(os.path.join(filename,str(classname)+".pyml.svm")); I am using the latest version of PyML (0.7.2, although PyML.__version__ is 0.7.0). When I construct the classifier with a training dataset, the reported accuracy is ~0.87. When I then save it and reload it, the accuracy is less than 0.001. So, there is something here that I am clearly not persisting correctly, although what that may be is completely non-obvious to me. Would you happen to know what that is?

Mako templates use old version until I manually update template files

I periodically get this problem where all of a sudden mako is using old versions of templates, and it's not until I manually go and update the template files that they'll use the current version. I'm using ./manage.py runserver I think it's usually after I update using source control, but it's intermittent, and I can't reliably reproduce the problem.

CSharp -- PInvokeStackImbalance detected on a well documented function?

OdbcCommand on Stored Procedure - "Parameter not supplied" error on Output parameter

- by Aaron

I'm trying to execute a stored procedure (against SQL Server 2005 through the ODBC driver) and I recieve the following error: Procedure or Function 'GetNodeID' expects parameter '@ID', which was not supplied. @ID is the OUTPUT parameter for my procedure, there is an input @machine which is specified and is set to null in the stored procedure: ALTER PROCEDURE [dbo].[GetNodeID] @machine nvarchar(32) = null, @ID int OUTPUT AS BEGIN SET NOCOUNT ON; IF EXISTS(SELECT * FROM Nodes WHERE NodeName=@machine) BEGIN SELECT @ID = (SELECT NodeID FROM Nodes WHERE NodeName=@machine) END ELSE BEGIN INSERT INTO Nodes (NodeName) VALUES (@machine) SELECT @ID = (SELECT NodeID FROM Nodes WHERE NodeName=@machine) END END The following is the code I'm using to set the parameters and call the procedure: OdbcCommand Cmd = new OdbcCommand("GetNodeID", _Connection); Cmd.CommandType = CommandType.StoredProcedure; Cmd.Parameters.Add("@machine", OdbcType.NVarChar); Cmd.Parameters["@machine"].Value = Environment.MachineName.ToLower(); Cmd.Parameters.Add("@ID", OdbcType.Int); Cmd.Parameters["@ID"].Direction = ParameterDirection.Output; Cmd.ExecuteNonQuery(); _NodeID = (int)Cmd.Parameters["@Count"].Value; I've also tried using Cmd.ExecuteScalar with no success. If I break before I execute the command, I can see that @machine has a value. If I execute the procedure directly from Management Studio, it works correctly. Any thoughts? Thanks

Storing an object to use in multiple classes

- by Aaron Sanders

I am wondering the best way to store an object in memory that is used in a lot of classes throughout an application. Let me set up my problem for you: We have multiple databases, 1 per customer. We also have a master table and each row is detailed information about the databases such as database name, server IP it's located and a few config settings. I have an application that loops through those multiple databases and runs some updates on them. The settings I mentioned above are updated each loop iteration into memory. The application then runs through series of processes that include multiple classes using this data. The data never changes during the processes, only during the loop iteration. The variables are related to a customer, so I have them stored in a customer class. I suppose I could make all of the members shared or should I use a singleton for the customer class? I've never actually used a singleton, only read they are good in this type of situation. Are there better solutions to this type of scenario? Also, I could have plans for this application to be multithreaded later. Sorry if this is confusing. If you have questions, let me know and I will answer them. Thanks for your help.
