"Jquery autocomplete with coldfusion",
"I'm trying to do a simple jquery autocomplete using ColdFusion, based on Jens great example.\n\nHTML:\n\n<form name=\"merchantSearch\" id=\"merchantSearch\" method=\"post\" action=\"/index.cfm/shop.store/\"> \n <input type=\"text\" name=\"state\" id=\"state\"/>\n <input type=\"submit\" name=\"submit\" id=\"submit\" value=\"\" class=\"searchButton\"/> \n <input type=\"hidden\" name=\"merchantID\" id=\"merchantID\"/>\n </form>\n\n\nThe entire json struct shows in the select box. When you click on one, it populates it with the entire struct. The autocomplete seems really confused about what to do with the json.\n\nColdFusion:\n\n <cfloop query=\"request.qMerchants\">\n <cfset request.merchantStruct = StructNew()>\n <cfset request.merchantStruct[\"merchantID\"] = #request.qMerchants.merchantID#>\n\n <cfset request.altText = altText...\"\n <cfset request.merchantStruct[\"label\"] = #request.qMerchants.merchant#&#request.altText#>\n\n <cfset ArrayAppend(request.merchantArray, request.merchantStruct)>\n</cfloop>\n\n\n<cfoutput> \n #serializeJSON(request.merchantArray)#\n</cfoutput>\n\n\nJquery:\n\n$(document).ready(function(){\n\n $(\"#state\").autocomplete( \n \"xhr/merchantAutoComplete.cfm\", \n {\n minLength:2, \n minchars:2,\n autoFill:false,\n select:function(event,ui) {\n $(\"#merchantID\").val(ui.item.merchantID);\n $(\"#merchant\").val(ui.item.merchant);\n }\n }\n ); \n\n});\n\n\nThe CF file returns the json formatted data, but it stays as json. The results end up like:\n\n[\n {\"label\":\"AAA 112 pts\\/$\",\"merchantID\":6},\n {\"label\":\"BBB 64 pts\\/$\",\"merchantID\":62},\n {\"label\":\"CCC 48 pts\\/$\",\"merchantID\":277},\n {\"label\":\"DDD 144 pts\\/$\",\"merchantID\":278},\n {\"label\":\"EEE 80 pts\\/$\",\"merchantID\":279}\n]\n\n\nAnd selecting one puts the whole json struct in the select box. I assume I have the right group of jquery, jquery UI, and css files to get anything back, but I'll post them just to make this really bloated:\n\n<script src=\"/assets/js/jquery/jquery.autocomplete.js\"></script>\n<script src=\"/assets/js/jquery/jquery1.4.2.js\"></script>\n<link rel=\"stylesheet\" href=\"/assets/css/jquery.autocomplete.css\" type=\"text/css\" media=\"screen, projection\" />\n<script src=\"/assets/js/jquery/jquery-ui-1.8.2.js\"></script>\n\n\nI'm sure its a 'label/value' issue, but nothing seems to help. Any suggestions would be awesome..Thanks!! Jon\n\nStill haven't figured this out. I think the remote call is returning a properly formatted json struct. Looks like: \n[{\"value\":\"FedEx Office 48 pts per $\",\"id\":578},{\"value\":\"Fergie Shoes.com 88 pts per $\",\"id\":784}]\n\nthe autocomplete js looks like:\n\n $(document).ready(function(){\n $(\"#merchantLabel\").autocomplete( \n \"xhr/merchantAutoComplete.cfm\", \n { \n select:function(event,ui) {\n $(\"#merchantID\").val(ui.item.id); \n return false;\n }\n }\n ); \n });\n\n\nThe html looks like:\n\n <form name=\"merchantSearch\" id=\"merchantSearch\" method=\"post\" action=\"/index.cfm/shop.store/\"> \n <input type=\"text\" name=\"merchantLabel\" id=\"merchantLabel\"/>\n <input type=\"submit\" name=\"submit\" id=\"submit\" value=\"\" class=\"searchButton\"/> \n <input type=\"hidden\" name=\"merchantID\" id=\"merchantID\"/> \n </form>"

The closest thing to a login attempt request that I see is a HTTP Request called '/_ah/conflogin', though it is a get request and not a post and the only variable present there is something called 'state'. \n\nAm I approaching this all wrong. Will Jmeter allow me to load test an authorized app in app engine? I found very scare resources on this online..Though I have found Google IO talks mentioning Jmeter as a stress testing tool for a web app in engine but with no details as to how to.

When I do this I will get 4 holes, see picture in the link below. Can someone please help me solve this problem\n\nhttp://i.stack.imgur.com/EY3uD.jpg"

"How can I encode this query string?",
"I'm trying to implement a payment processor. In order to validate that the response is legitimate, I have to take the query string and append a validation key, then perform an MD5 hash and match my hashed values to theirs.\n\nThe payment processor is generating their hash based on a querystring like the following:\n\n\n trnId=10000041\n &messageText=Duplicate+Transaction+%2D+This+transaction+has+already+been+approved\n &trnAmount=11.20\n &trnDate=6%2F8%2F2011+12%3A32%3A20+PM\n &trnEmailAddress=john%2Edoe%40gmail%2Ecom\n &avsMessage=Address+Verification+not+performed+for+this+transaction%2E\n &ref1=aab02ccd%2D7d17%2D4d09%2Da30c%2Dad6324fe33f1 \n\n\nNow if I were to call QueryString[\"messageText\"] I would get \"Duplicate Transaction - This transaction has already been approved\". I can't use that, as I need the + and %2D\n\nSo to generate my string I do something like this:\n\nNameValueCollection queryString = new NameValueCollection(QueryString);\nqueryString.Remove(\"hashValue\");\n\nList<string> parameters = new List<string>();\nforeach(string qs in queryString.Keys)\n parameters.Add(qs + \"=\" + HttpUtility.UrlEncode(QueryString[qs]));\n\nstring value = string.Join(\"&\", parameters.ToArray());\n\n\nMy resulting string:\n\n\n trnId=10000041\n &messageText=Duplicate+Transaction+-+This+transaction+has+already+been+approved\n &trnAmount=11.20\n &trnDate=6%2f8%2f2011+1%3a05%3a09+PM\n &trnEmailAddress=john.doe%40gmail.com\n &avsMessage=Address+Verification+not+performed+for+this+transaction.\n &ref1=aab02ccd-7d17-4d09-a30c-ad6324fe33f1 \n\n\nThat is a little closer, but with 2 issues, the dashes and periods are not encoded, and the encoding generated lowercase instead of upper case. %2f instead of %2F.\n\nIs there any way to fix this without doing a string.replace? A different method I could call that would provide the results I want?"

"WCF service contract design. Is a use case controller appropriate?",
"First off, apologies if this question has been asked before but I couldn't find anything that answers this directly.\n\nHere's my problem. I've inherited a product which has been designed to be so flexible that populating pretty much every combobox and textblock on the (silverlight) form requires a service request. Some of the screens take upward of 15 separate requests just to populate!\n\nNow I've worked with WCF web services on a number of occasions and having service contracts split into small discrete operations has never been too much of a hit,..sadly this is not the case for this project. So it left me wondering...\n\nThere are no plans to expose the service outside of our own walls. There are no plans to write another client for this particular service. So couldn't I just write a 'use case controller' at the service end? So, in a 'create complaint' screen, instead of having a list of requests like...\n\n\nGetComplaintTypes\nGetCustomerTypes\nGetAreaDetails\nAnd so on...\n\n\nto populate the form I would just have a single operation contract called 'GetCreateComplaintData'. It seems crazy to have so many operations exposed in such granularity when there's only one client which then has to aggregate and synchronise all these requests into something meaningful. Why not expose something meaningful in the first place?\n\nMore to the point, if you don't intend on exposing the service API to third parties isn't this a better strategy than exposing CRUD ops for tables in the DB?\n\nAll help and opinions are appreciated.\nThanks in advance."

"In pandas, is inplace = True considered harmful, or not?",
"This has been discussed before, but with conflicting answers:\n\nin-place is good!\nin-place is bad!\n\nWhat I'm wondering is:\n\nWhy is inplace = False the default behavior?\nWhen is it good to change it? (well, I'm allowed to change it, so I guess there's a reason).\nIs this a safety issue? that is, can an operation fail/misbehave due to inplace = True?\nCan I know in advance if a certain inplace = True operation will "really" be carried out in-place?\n\n\nMy take so far:\n\nMany Pandas operations have an inplace parameter, always defaulting to False, meaning the original DataFrame is untouched, and the operation returns a new DF.\nWhen setting inplace = True, the operation might work on the original DF, but it might still work on a copy behind the scenes, and just reassign the reference when done.\n\npros of inplace = True:\n\nCan be both faster and less memory hogging (the first link shows reset_index() runs twice as fast and uses half the peak memory!).\n\npros of inplace = False :\n\nAllows chained/functional syntax: df.dropna().rename().sum()... which is nice, and offers a chance for lazy evaluation or a more efficient re-ordering (though I don't think Pandas is doing this).\nWhen using inplace = True on an object which is potentially a slice/view of an underlying DF, Pandas has to do a SettingWithCopy check, which is expensive. inplace = False avoids this.\nConsistent & predictable behavior behind the scenes.\n\nSo, putting the copy-vs-view issue aside, it seems more performant to always use inplace = True, unless specifically writing a chained statement. But that's not the default Pandas opt for, so what am I missing?"

"AVAudioPlayer throws breakpoint in debug mode",
"Every time I load the app it stops as if I had set a breakpoint on this line:\n\nself.audioPlayer = \n [[[AVAudioPlayer alloc] initWithData:[dataPersister loadData:self.fileName] \n error:&outError] autorelease];\n\n\nThere's no breakpoint above or any place near this line. It only happens when I run the app in debug mode and nothing crashes after the breakpoint. The app works as nothing happened when I click \"Continue program execution\".\n\nThis is the loadData method, which is called with initWithData:\n\n-(NSData*)loadData:(NSString*)fileName\n{\n NSString *dataPath = [self.path stringByAppendingPathComponent:fileName];\n dataPath = [dataPath stringByStandardizingPath];\n NSData *data = [[[NSData alloc] initWithContentsOfFile:dataPath]autorelease ];\n return data;\n}\n\n\nThe loadData function seems to be working fine. The requested mp3 file is loaded and played without any problems after the breakpoint.\n\nDo you have any idea what I'm doing wrong?\n\nEDIT:\nI ran a backtrace when it stops at the breakpoint. This was the output:\n\n\n(lldb) bt\n* thread #1: tid = 0x1c03, 0x30df1724 libc++abi.dylib`__cxa_throw, stop reason = breakpoint 1.2\n frame #0: 0x30df1724 libc++abi.dylib`__cxa_throw\n frame #1: 0x36403a24 AudioToolbox`ID3ParserHandle::ID3ParserHandle(void*, long (*)(void*, unsigned long, unsigned long, unsigned long, void**, unsigned long*)) + 452\n frame #2: 0x36403b0e AudioToolbox`ID3ParserOpen + 142\n frame #3: 0x3635bd16 AudioToolbox`MPEGAudioFile::ParseID3Tags() + 58\n frame #4: 0x3635b9aa AudioToolbox`MPEGAudioFile::ParseAudioFile() + 26\n frame #5: 0x3631723e AudioToolbox`AudioFileObject::DoOpenWithCallbacks(void*, long (*)(void*, long long, unsigned long, void*, unsigned long*), long (*)(void*, long long, unsigned long, void const*, unsigned long*), long long (*)(void*), long (*)(void*, long long)) + 166\n frame #6: 0x36316480 AudioToolbox`AudioFileOpenWithCallbacks + 612\n frame #7: 0x31f4c1ec AVFoundation`-[AVAudioPlayer initWithData:error:] + 120\n\n\n\"SOLUTION\": It turns out, if I disable exception breakpoint for all exceptions and only use breakpoint for Objective-C exceptions the problem disappears.

"What is the preferred way to validate data in an AngularJS app?",
"I've heard of a couple of different approaches to providing the validation specs to an Angular UI. \n\nOne is to build it in on the UI side with a configuration file specifying such things as field length, which fields are required, and valid selections as examples of items to be validated.\n\nAnother approach is to have the UI query a service on the backend to provide these validations by pulling them out of a database. There is a logical grouping of validations, so the service would specify the group ID and the validations would be returned.\n\nI can see advantages to both, but the database side may start to feel like a UI framework instead of just a set of validations. You still need to specify the endpoints for CRUD operations, but putting that in the backend would make the whole thing pretty heavy.\n\nThanks"

"Using ajax response as the function's argument",
"I'm trying to use the ajax response as an argument for the function drawing the chart with google charts.\n\nThis is the JS code:\n\ndata.addRows([['One', 5], ['Two', 2]]);\n\n\nAs you can see, the argument contains a couple of square brackets with the \"chart's unit\" name and its value. Everything works. However when I pass ajax responseText as the argument, it doesn't work at all.\n\ndata.addRows(xmlhttp.responseText);\n\n\nThe PHP code returns json_encode($value), where the $value variable is this string:\n[[one, 5], [two, 2]]\n\nSo as the result I get:\n\n\"[['one', 5], ['two', 2]]\"\n\n\nBTW. I also tried removing double quotes from the string in the JS code - still no results.\n\nWhat's wrong? The firebug gives me some strange errors: Argument given to addRows must be either a number or an array...\n\nHow should I fix this?"

"How to attach EventTrigger in code behind in Silverlight 4",
"My question is the following:\n\nI have a grid and I attached the SelectedIndexChanged event the following way in the xaml file:\n\n\"<cc:DetailViewGrid AutoGenerateColumns=\"False\" HorizontalAlignment=\"Stretch\" Margin=\"0,0,0,0\" Name=\"dgAcitivityList\" VerticalAlignment=\"Stretch\" ItemsSource=\"{Binding EntityList}\" SelectionMode=\"Single\" IsReadOnly=\"False\">\n <interactivity:Interaction.Triggers>\n <interactivity:EventTrigger EventName=\"SelectionChanged\">\n <interactivity:InvokeCommandAction Command=\"{Binding SelectedItemChangeCommand}\" CommandParameter=\"{Binding SelectedItem, ElementName=dgAcitivityList}\"/>\n </interactivity:EventTrigger>\n </interactivity:Interaction.Triggers>\"\n\n\nBut I want to attach this event in code behind. I ctreated an own grid that is inherited from windows grid, and I put this code to own control.\n\n public override void OnApplyTemplate()\n {\n //base.OnApplyTemplate();\n\n System.Windows.Interactivity.EventTrigger selectedItemChangedTrigger = new System.Windows.Interactivity.EventTrigger(\"SelectionChanged\");\n\n System.Windows.Interactivity.InvokeCommandAction action = new System.Windows.Interactivity.InvokeCommandAction();\n\n action.CommandName = \"{Binding SelectedItemChangeCommand}\";\n\n action.CommandParameter = string.Format(\"{{Binding SelectedItem, ElementName={0}}}\", this.Name);\n\n selectedItemChangedTrigger.Actions.Add(action);\n\n System.Windows.Interactivity.Interaction.GetTriggers(this).Add(selectedItemChangedTrigger);\n\n base.OnApplyTemplate();\n }\n\n\nIs this solution proper? It's not working but I'm not sure that I should put this code in the OnApplyTemplate() method."
