• error wordpress, adjusted sidebar.php to show latest 10 posts

  - by Andy

  Hi, I'm trying to edit my sidebar.php file in my current them WP is using to display the last # of posts (only the titles) as links. I tried using the example of http://codex.wordpress.org/Integrating_WordPress_with_Your_Website but I always get the error on the line that states where the file wp-blog-header can be found. the error when opening the index blog page where the sidebar should be shown: // Get the last 3 posts. Warning: require(/blog/folder/wp-blog-header.php) [function.require]: failed to open stream: No such file or directory in /blog/folder/wp-content/themes/default/sidebar.php on line 7 So what is wrong? Is there a way to permanently embed a function in my html template page that retrieves the latest few posts everytime an article is displayed on the template page? the code: <?php require('/the/path/to/your/wp-blog-header.php'); ?> <?php $posts = get_posts('numberposts=10&order=ASC&orderby=post_title'); foreach ($posts as $post) : start_wp(); ?> <?php the_title(); ?> <?php the_excerpt(); ?> <?php endforeach; ?>

• Caching sitemaps in django

  - by michuk

  I implemented a simple sitemap class using django's default sitemap app. As it was taking a long time to execute, I added manual caching: class ShortReviewsSitemap(Sitemap): changefreq = "hourly" priority = 0.7 def items(self): # try to retrieve from cache result = get_cache(CACHE_SITEMAP_SHORT_REVIEWS, "sitemap_short_reviews") if result!=None: return result result = ShortReview.objects.all().order_by("-created_at") # store in cache set_cache(CACHE_SITEMAP_SHORT_REVIEWS, "sitemap_short_reviews", result) return result def lastmod(self, obj): return obj.updated_at The problem is that memcache allows only max 1MB object. This one was bigger that 1MB, so storing into cache failed: >7 SERVER_ERROR object too large for cache The problem is that django has an automated way of deciding when it should divide the sitemap file into smalled ones. According to the docs (http://docs.djangoproject.com/en/dev/ref/contrib/sitemaps/): You should create an index file if one of your sitemaps has more than 50,000 URLs. In this case, Django will automatically paginate the sitemap, and the index will reflect that. What do you think would be the best way to enable caching sitemaps? - Hacking into django sitemaps framework to restrict a single sitemap size to, let's say, 10,000 records seems like the best idea. Why was 50,000 chosen in the first place? Google advice? random number? - Or maybe there is a way to allow memcached store bigger files? - Or perhaps onces saved, the sitemaps should be made available as static files? This would mean that instead of caching with memcached I'd have to manually store the results in the filesystem and retrieve them from there next time when the sitemap is requested (perhaps cleaning the directory daily in a cron job). All those seem very low level and I'm wondering if an obvious solution exists...

• ASP.NET MVC - Binding a Child Entity to the Model

  - by Nathan Taylor

  This one seems painfully obvious to me, but for some reason I can't get it working the way I want it to. Perhaps it isn't possible the way I am doing it, but that seems unlikely. This question may be somewhat related: http://stackoverflow.com/questions/1274855/asp-net-mvc-model-binding-related-entities-on-same-page. I have an EditorTemplate to edit an entity with multiple related entity references. When the editor is rendered the user is given a drop down list to select related entities from, with the drop down list returning an ID as its value. <%=Html.DropDownListFor(m => m.Entity.ID)%> When the request is sent the form value is named as expected: "Entity.ID", however my strongly typed Model defined as an action parameter doesn't have Entity.ID populated with the value passed in the request. public ActionResult AddEntity(EntityWithChildEntities entityWithChildEntities) { } I tried fiddling around with the Bind() attribute and specified Bind(Include = "Entity.ID") on the entityWithChildEntities, but that doesn't seem to work. I also tried Bind(Include = "Entity"), but that resulted in the ModelBinder attempting to bind a full "Entity" definition (not surprisingly). Is there any way to get the default model binder to fill the child entity ID or will I need to add action parameters for each child entity's ID and then manually copy the values into the model definition?

• LINQ query code for complex merging of data.

  - by Stacey

  I've posted this before, but I worded it poorly. I'm trying again with a more well thought out structure. Re-writing this a bit to make it more clear. I have the following code and I am trying to figure out the shorter linq expression to do it 'inline'. Please examine the "Run()" method near the bottom. I am attempting to understand how to join two dictionaries together based on a matching identifier in one of the objects - so that I can use the query in this sort of syntax. var selected = from a in items.List() // etc. etc. select a; This is my class structure. The Run() method is what I am trying to simplify. I basically need to do this conversion inline in a couple of places, and I wanted to simplify it a great deal so that I can define it more 'cleanly'. class TModel { public Guid Id { get; set; } } class TModels : List<TModel> { } class TValue { } class TStorage { public Dictionary<Guid, TValue> Items { get; set; } } class TArranged { public Dictionary<TModel, TValue> Items { get; set; } } static class Repository { static public TItem Single<TItem, TCollection>(Predicate<TItem> expression) { return default(TItem); // access logic. } } class Sample { public void Run() { TStorage tStorage = new TStorage(); // access tStorage logic here. Dictionary<TModel, TValue> d = new Dictionary<TModel, TValue>(); foreach (KeyValuePair<Guid, TValue> kv in tStorage.Items) { d.Add(Repository.Single<TModel, TModels>(m => m.Id == kv.Key),kv.Value); } } }

• Log off from Remote Desktop Session does not closing Session, showing the login screen again on Wind

  - by Santhosha

  Hi As per requirement we have written one custom GINA. I have observed one interesting behavior in Windows XP 32 Bit(SP2). Customized GINA internally calls windows default Windows GINA(msgina.dll) and shows one extra window as per our requirement. I used to do remote desktop to XP machine from my machine. After replacing Windows GINA with customized GINA I tried to log off from the XP Machine(I am Using Remote Desktop Connection to log in), Log off completes successfully(After showing saving your settings, Closing network connections etc) and I will get log in screen which we get during log on, this is not expected comapred to other flavors of Windows OD. Where as in other operating systems such as Windows XP 64 Bit/ Windows 2003 32/64 Bit even after replacing the Windows Gina with custom GINA remote desktop session closes after log off from the machine. I have tried installing Novell GINA on Windows XP 32 Bit but i have not find any issue with that. I have Tried upgrading XP SP2 to SP3, still i am facing the same issue. Whether anyone faced Such issues when worked with Windows GINA? Thanks in advance Santhosha K S

• General many-to-many relationship problem ( Postgresql )

  - by David

  Hi, i have two tables: CREATE TABLE "public"."auctions" ( "id" VARCHAR(255) NOT NULL, "auction_value_key" VARCHAR(255) NOT NULL, "ctime" TIMESTAMP WITHOUT TIME ZONE NOT NULL, "mtime" TIMESTAMP WITHOUT TIME ZONE NOT NULL, CONSTRAINT "pk_XXXX2" PRIMARY KEY("id"), ); and CREATE TABLE "public"."auction_values" ( "id" NUMERIC DEFAULT nextval('default_seq'::regclass) NOT NULL, "fk_auction_value_key" VARCHAR(255) NOT NULL, "key" VARCHAR(255) NOT NULL, "value" TEXT, "ctime" TIMESTAMP WITHOUT TIME ZONE NOT NULL, "mtime" TIMESTAMP WITHOUT TIME ZONE NOT NULL, CONSTRAINT "pk_XXXX1" PRIMARY KEY("id"), ); if i want to create a many-to-many relationship on the auction_value_key like this: ALTER TABLE "public"."auction_values" ADD CONSTRAINT "auction_values_fk" FOREIGN KEY ("fk_auction_value_key") REFERENCES "public"."auctions"("auction_value_key") ON DELETE NO ACTION ON UPDATE NO ACTION NOT DEFERRABLE; i get this SQL error: ERROR: there is no unique constraint matching given keys for referenced table "auctions" Question: As you might see, i want "auction_values" to be be "reused" by different auctions without duplicating them for every auction... So i don't want a key relation on the "id" field in the auctions table... Am i thinking wrong here or what is the deal? ;) Thanks

• mprotect - how aligning to multiple of pagesize works?

  - by user299988

  Hi, I am not understanding the 'aligning allocated memory' part from the mprotect usage. I am referring to the code example given on http://linux.die.net/man/2/mprotect char *p; char c; /* Allocate a buffer; it will have the default protection of PROT_READ|PROT_WRITE. */ p = malloc(1024+PAGESIZE-1); if (!p) { perror("Couldn't malloc(1024)"); exit(errno); } /* Align to a multiple of PAGESIZE, assumed to be a power of two */ p = (char *)(((int) p + PAGESIZE-1) & ~(PAGESIZE-1)); c = p[666]; /* Read; ok */ p[666] = 42; /* Write; ok */ /* Mark the buffer read-only. */ if (mprotect(p, 1024, PROT_READ)) { perror("Couldn't mprotect"); exit(errno); } For my understanding, I tried using a PAGESIZE of 16, and 0010 as address of p. I ended up getting 0001 as the result of (((int) p + PAGESIZE-1) & ~(PAGESIZE-1)). Could you please clarify how this whole 'alignment' works? Thanks,

• VEMap and a GeoRSS feed(hosted separately)

  - by Alexis Abril

  The scenario is as follows: A WCF web service exists that outputs a valid GeoRSS feed. This lives in its own domain as a number of different applications have access to it. A web page(on a different site) has been created with an instance of a VEMap(Bing/Virtual Earth map object). Now, VEMap can accept an input feed in this format via the following: var layer = new VEShapeLayer(); var veLayerSpec = new VEShapeSourceSpecification(VEDataType.GeoRSS, "someurl", layer); map.ImportShapeLayerData(veLayerSpec, onComplete, true); onComplete is a callback function I'm using to replace the default pin graphic with something custom. The question is in regards to "someurl", which is a path to a local xml file containing the geographic information(georss simple format). I've realized this feed and the map must be hosted in the same domain, so I've created a generic handler that reads the remote feed and returns it in the same format. var veLayerSpec = new VEShapeSourceSpecification(VEDataType.GeoRSS, "/somelocalhandler.ashx", layer); When I do this, I get the VEMap error("z is null"). This is the same error one would receive when trying to access a remote feed. When I copy the feed into a local xml file(ie, "feed.xml") there is no error. The order of operations is currently: remote feed - local handler - VEMap import If I'm over complicating this procedure, let me know! I'm a bit new to the Bing Maps API and might have missed something. Any assistance is appreciated.

• MySQL Cursor Issue

• Iterate through main function in C?

  - by Mohit Deshpande

  Here is my main function: int main(int argc, char **argv) { LoadFile(); Node *temp; char *key; switch (GetUserInput()) { case 1: temp = malloc(sizeof(Node)); printf("\nEnter the key of the new node: "); scanf("%s", temp->key); printf("\nEnter the value of the new node: "); scanf("%s", temp->value); AddNode(temp); free(temp); break; case 2: key = malloc(sizeof(char *)); printf("Enter the key of the node you want to delete: "); scanf("%s", key); DeleteNode(key); free(key); break; case 3: PrintAll(); break; case 4: SaveFile(); break; case 5: return 0; break; default: printf("\nWrong choice!\n"); break; } return 0; } The only problem with it is that after any case statement breaks, the program just exits out. I understand why, but I don't know how to fix it. I want the program to repeat itself each time even after the case statements. Would I just say: main(argc, argv); before every break statement?

• Serializing a part of object graph

  - by Felix

  Hi all, I have a problem regarding Java custom serialization. I have a graph of objects and want to configure where to stop when I serialize a root object from client to server. Let's make it a bit concrete, clear by giving a sample scenario. I have Classes of type Company Employee (abstract) Manager extends Employee Secretary extends Employee Analyst extends Employee Project Here are the relations: Company(1)---(n)Employee Manager(1)---(n)Project Analyst(1)---(n)Project Imagine, I'm on the client side and I want to create a new company, assign it 10 employees (new or some existing) and send this new company to the server. What I expect in this scenario is to serialize the company and all bounding employees to the server side, because I'll save the relations on the database. So far no problem, since the default Java serialization mechanism serializes the whole object graph, excluding the field which are static or transient. My goal is about the following scenario. Imagine, I loaded a company and its 1000 employees from the server to the client side. Now I only want to rename the company's name (or some other field, that directly belongs to the company) and update this record. This time, I want to send only the company object to the server side and not the whole list of employees (I just update the name, the employees are in this use case irrelevant). My aim also includes the configurability of saying, transfer the company AND the employees but not the Project-Relations, you must stop there. Do you know any possibility of achieving this in a generic way, without implementing the writeObject, readObject for every single Entity-Object? What would be your suggestions? I would really appreciate your answers. I'm open to any ideas and am ready to answer your questions in case something is not clear.

• production vs dev server content-disposition filename encoding

  - by rgripper

  I am using asp.net mvc3, download file in the same browser (Chrome 22). Here is the controller code: [HttpPost] public ActionResult Uploadfile(HttpPostedFileBase file)//HttpPostedFileBase file, string excelSumInfoId) { ... return File( result.Output, "application/vnd.ms-excel", String.Format("{0}_{1:yyyy.MM.dd-HH.mm.ss}.xls", "????????????", DateTime.Now)); } On my dev machine I download a programmatically created file with the correct name "????????????_2012.10.18-13.36.06.xls". Response: Content-Disposition:attachment; filename*=UTF-8''%D0%A1%D1%83%D0%BC%D0%BC%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D0%BD%D0%B8%D0%B5_2012.10.18-13.36.06.xls Content-Length:203776 Content-Type:application/vnd.ms-excel Date:Thu, 18 Oct 2012 09:36:06 GMT Server:ASP.NET Development Server/10.0.0.0 X-AspNet-Version:4.0.30319 X-AspNetMvc-Version:3.0 And from production server I download a file with the name of the controller's action + correct extension "Uploadfile.xls", which is wrong. Response: Content-Disposition:attachment; filename="=?utf-8?B?0KHRg9C80LzQuNGA0L7QstCw0L3QuNC1XzIwMTIuMTAuMTgtMTMuMzYu?=%0d%0a =?utf-8?B?NTUueGxz?=" Content-Length:203776 Content-Type:application/vnd.ms-excel Date:Thu, 18 Oct 2012 09:36:55 GMT Server:Microsoft-IIS/7.5 X-AspNet-Version:4.0.30319 X-AspNetMvc-Version:3.0 X-Powered-By:ASP.NET Web.config files are the same on both machines. Why does filename gets encoded differently for the same browser? Are there any kinds of default settings in web.config that are different on machines that I am missing?

• Ruby ICalendar Gem: How to get e-mail reminders working.

  - by Jenny

  I'm trying to work out how to use the icalendar ruby gem, found at: http://icalendar.rubyforge.org/ According to their tutorial, you do something like: cal.event.do # ...other event properties alarm do action "EMAIL" description "This is an event reminder" # email body (required) summary "Alarm notification" # email subject (required) attendees %w(mailto:[email protected] mailto:[email protected]) # one or more email recipients (required) add_attendee "mailto:[email protected]" remove_attendee "mailto:[email protected]" trigger "-PT15M" # 15 minutes before add_attach "ftp://host.com/novo-procs/felizano.exe", {"FMTTYPE" => "application/binary"} # email attachments (optional) end alarm do action "DISPLAY" # This line isn't necessary, it's the default summary "Alarm notification" trigger "-P1DT0H0M0S" # 1 day before end alarm do action "AUDIO" trigger "-PT15M" add_attach "Basso", {"VALUE" => ["URI"]} # only one attach allowed (optional) end So, I am doing something similar in my code. def schedule_event puts "Scheduling an event for " + self.title + " at " + self.start_time start = self.start_time endt = self.start_time title = self.title desc = self.description chan = self.channel.name # Create a calendar with an event (standard method) cal = Calendar.new cal.event do dtstart Program.convertToDate(start) dtend Program.convertToDate(endt) summary "Want to watch" + title + "on: " + chan + " at: " + start description desc klass "PRIVATE" alarm do action "EMAIL" description desc # email body (required) summary "Want to watch" + title + "on: " + chan + " at: " + start # email subject (required) attendees %w(mailto:[email protected]) # one or more email recipients (required) trigger "-PT25M" # 25 minutes before end end However, I never see any e-mail sent to my account... I have even tried hard coding the start times to be Time.now, and sending them out 0 minutes before, but no luck... Am I doing something glaringly wrong?

• Best terminal environment for Cygwin/Windows?

  - by Anders Sandvig

  Today I run Cygwin with rxvt using the following startup line: rxvt -bg black -sl 8192 -fg white -sr -g 150x56 -fn "Fixedsys" -e /usr/bin/bash --login -i This gives me a resizeable native Windows window which is much better than the standard "DOS box" the default cygwin.bat provides. However, the current configuration does have a couple of issues: I am not able to enter non-ASCII characters into the terminal window (i.e. æ, ø, å and Æ, Ø, Å, which I use semi-frequently. In fact, the terminal will not even accept them when I paste them into the window. If I paste a string like "bølle" (Norwegian for "bulley"), all I get is "blle". I am not able to render UTF-8 character, they only show as ?, even if they are supported by the font (i.e. when rendering the same characters in ISO-8859-1 they show just fine.). I am running English Windows Vista with locale and keyboard layout set to Norwegian (ISO-8859-1 character set?), but I've had the exact same issue on Windows 2000 and XP. Anyone knows how to fix this (i.e. a better way to configure rxvt)? Apart from the issues mentioned above, I'm very happy with rxvt, so if I find a way to resolve them I'd like to continue using it. However, if the issues are not (easily) solvable, are the any other good terminal solutions for Cygwin? Update The solution provided by Andy and Mattias (editing the .inputrc file) did solve the input problem, but output rendering is still an issue. Output is fine when I render in ISO-8859-1, but when using UTF-8 I only get ? for non-ASCII characters. This behavior is consistent between rxvt, urxvt (under Cygwin XFree X Server), mintty and PuttyCyg. Is there a similar configuration file where output encoding can be set (i.e. the equivalent of setting output locale on a Linux system)?

• Matplotlib PDF export uses wrong font

  - by Konrad Rudolph

  I want to generate high-quality diagrams for a presentation. I’m using Python’s matplotlib to generate the graphics. Unfortunately, the PDF export seems to ignore my font settings. I tried setting the font both by passing a FontProperties object to the text drawing functions and by setting the option globally. For the record, here is a MWE to reproduce the problem: import scipy import matplotlib matplotlib.use('cairo') import matplotlib.pylab as pylab import matplotlib.font_manager as fm data = scipy.arange(5) for font in ['Helvetica', 'Gill Sans']: fig = pylab.figure() ax = fig.add_subplot(111) ax.bar(data, data) ax.set_xticks(data) ax.set_xticklabels(data, fontproperties = fm.FontProperties(family = font)) pylab.savefig('foo-%s.pdf' % font) In both cases, the produced output is identical and uses Helvetica (and yes, I do have both fonts installed). Just to be sure, the following doesn’t help either: matplotlib.rc('font', family = 'Gill Sans') Finally, if I replace the backend, instead using the native viewer: matplotlib.use('MacOSX') I do get the correct font displayed – but only in the viewer GUI. The PDF output is once again wrong. To be sure – I can set other fonts – but only other classes of font families: I can set serif fonts or fantasy or monospace. But all sans-serif fonts seem to default to Helvetica.

• Item rendered via a DataTemplate with any Background Brush renders selection coloring behind item.

  - by Mike L

  I have a ListBox which uses a DataTemplate to render databound items. The XAML for the datatemplate is as follows: <DataTemplate x:Key="NameResultTemplate"> <WrapPanel x:Name="PersonResultWrapper" Margin="0" Orientation="Vertical" Background="{Binding Converter={StaticResource NameResultToColor}, Mode=OneWay}" > <i:Interaction.Triggers> <i:EventTrigger EventName="MouseDown"> <cmd:EventToCommand x:Name="SelectPersonEventCommand" Command="{Binding Search.SelectedPersonCommand, Mode=OneWay, Source={StaticResource Locator}}" CommandParameter="{Binding Mode=OneWay}" /> </i:EventTrigger> </i:Interaction.Triggers> <TextBlock x:Name="txtPersonName" TextWrapping="Wrap" Margin="0" VerticalAlignment="Top" Text="{Binding PersonName}" FontSize="24" Foreground="Black" /> <TextBlock x:Name="txtAgencyName" TextWrapping="Wrap" Text="{Binding AgencyName}" HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0" FontStyle="Italic" Foreground="Black" /> <TextBlock x:Name="txtPIDORI" TextWrapping="Wrap" Text="{Binding PIDORI}" HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="0" FontStyle="Italic" Foreground="Black" /> <TextBlock x:Name="txtDescriptors" TextWrapping="Wrap" Text="{Binding DisplayDescriptors}" Margin="0" VerticalAlignment="Top" Foreground="Black"/> <Separator Margin="0" Width="400" /> </WrapPanel> </DataTemplate> Note that there is a value converter called NameResultToColor which changes the background brush of the rendered WrapPanel to gradient brush depending on certain scenarios. All of this works as I'd expect, except when you click on any of the rendered ListBox items. When you click one, there is only the slightest sign of the selection coloring (the default bluish color). I can see a trace bit of it underneath my gradient-brushed item. If I reset the background brush to "no brush" then the selection rendering works properly. If I set the background brush to a solid color, it also fails to render as I'd expect. How can I get the selection coloring to be on top? What is trumping the selection rendering?

• jquery validator message styling error in IE08 only when customised using errorPlacement function

  - by John Slaytor

  Going back to the errorplacement solution by Nadia (http://stackoverflow.com/questions/860055/jquery-override-default-validation-error-message-display-css-popup-tooltip-like) I have tried it and it works like a charm in Safari and Firefox but causes IE08 to bypass the jqueryvalidator and go straight to the server side validator. My code is this - as soon as I insert 'error element.... it is unstable in IE08. All help much appreciated <script type="text/javascript"> $(document).ready(function() { $("#sampleform").validate({ rules: { dinername: "required", venue: "required", contact: "required", dinertelephone: "required", venuetime: "required", numberdiners: "required", dineremail: { required: true, email: true}, datepicker: { required: true,date: true} }, messages: { dinername: "Your name?", numberdiners: "How many guests?", dinertelephone: "Your mobile?", venue: "Which restaurant?", venuetime: "Your arrival time?", datepicker: "Your booking date?", dineremail: "Please enter a valid email address", }, errorElement: "div", errorPlacement: function(error, element) { element.before(error); offset = element.offset(); error.css('right', offset.right); error.css('right', offset.right - element.outerHeight()); } }); }); </script> <script type="text/javascript"> $(function() { $("#datepicker") .datepicker({minDate: 0, maxDate: '+6M +0D',dateFormat: 'DD, d M yy',onClose: function() {$(this).valid();} }); }); </script> The relevant webpage is http://www.johnslaytor.com.au/nilgiris/forms/bookingform/bookingform.html

• How to access C arrays from assembler for Windows x64?

  - by 0xdword32

  I've written an assembler function to speed up a few things for image processing (images are created with CreateDIBSection). For Win32 the assembler code works without problems, but for Win64 I get a crash as soon as I try to access my array data. I put the relevant info in a struct and my assembler function gets a pointer to this struct. The struct pointer is put into ebx/rbx and with indexing I read the data from the struct. Any idea what I am doing wrong? I use nasm together with Visual Studio 2008 and for Win64 I set "default rel". C++ code: struct myData { tUInt32 ulParam1; void* pData; }; CallMyAssemblerFunction(&myData); Assembler Code: Win32: ... push ebp; mov ebp,esp mov ebx, [ebp + 8]; pointer to our struct mov eax, [ebx]; ulParam1 mov esi, [ebx + 4]; pData, 4 byte pointer movd xmm0, [esi]; ... Win64: ... mov rbx, rcx; pointer to our struct mov eax, [rbx]; ulParam1 mov rsi, [rbx + 4]; pData, 8 byte pointer movd xmm0, [rsi]; CRASH! ...

• Table cell in a split-view controller - selected cell becomes deselected when called by reloadData

  - by bpapa

  I'm working on a universal app that uses a SplitViewController to present a master-detail view. In the iPad HIG on Split Views, Apple states: In general, indicate the current selection in the left pane in a persistent way. This behavior helps people understand the relationship between the item in the left pane and the contents of the right pane. This is important because the contents of the right pane can change, but they should always remain related to the item selected in the left pane. So I'm trying to maintain selection state on the left. Easy enough when the user taps, I just remove the deselectRowAtIndexPath:animated: message from tableView:didSelectRowAtIndexPath: implementation. But, I also want the selection state to show up by default (without a user tap). I wound up putting this in my tableView:cellForRowAtIndexPath: implementation: if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { if (cellShouldBeSelected) cell.selected = YES; else cell.selected = NO; } The behavior I'm seeing, is that when the cells finall appear, for a fraction of a section the cell is indeed selected, but then the selection disappears without any user interaction. Any ideas? I set the new clearsSelectionOnViewWillAppear property to NO, but that doesn't seem to fix it, and it shouldn't really matter because I'm marking the cell as selected long after viewWillAppear is called - I'm actually doing it after some network activity and then sending the table view a reloadData message.

• Fixing color in scatter plots in matplotlib

  - by ajhall

  Hi guys, I'm going to have to come back and add some examples if you need them, which you might. But, here's the skinny- I'm plotting scatter plots of lab data for my research. I need to be able to visually compare the scatter plots from one plot to the next, so I want to fix the color range on the scatter plots and add in a colorbar to each plot (which will be the same in each figure). Essentially, I'm fixing all aspects of the axes and colorspace etc. so that the plots are directly comparable by eye. For the life of me, I can't seem to get my scatter() command to properly set the color limits in the colorspace (default)... i.e., I figure out my total data's min and total data's max, then apply them to vmin, vmax, for the subset of data, and the color still does not come out properly in both plots. This must come up here and there, I can't be the only one that wants to compare various subsets of data amongst plots... so, how do you fix the colors so that each data keeps it's color between plots and doesn't get remapped to a different color due to the change in max/min of the subset -v- the whole set? I greatly appreciate all your thoughts!!! A mountain-dew and fiery-hot cheetos to all! -Allen

• LINQtoSQL Custom Constructor off Partial Class?

  - by sah302

  Hi all, I read this question here: http://stackoverflow.com/questions/82409/is-there-a-way-to-override-the-empty-constructor-in-a-class-generated-by-linqtosq Typically my constructor would look like: public User(String username, String password, String email, DateTime birthday, Char gender) { this.Id = Guid.NewGuid(); this.DateCreated = this.DateModified = DateTime.Now; this.Username = username; this.Password = password; this.Email = email; this.Birthday = birthday; this.Gender = gender; } However, as read in that question, you want to use partial method OnCreated() instead to assign values and not overwrite the default constructor. Okay so I got this : partial void OnCreated() { this.Id = Guid.NewGuid(); this.DateCreated = this.DateModified = DateTime.Now; this.Username = username; this.Password = password; this.Email = email; this.Birthday = birthday; this.Gender = gender; } However, this gives me two errors: Partial Methods must be declared private. Partial Methods must have empty method bodies. Alright I change it to Private Sub OnCreated() to remove both of those errors. However I am still stuck with...how can I pass it values as I would with a normal custom constructor? Also I am doing this in VB (converted it since I know most know/prefer C#), so would that have an affect on this?

• SQL Server: Clustering by timestamp; pros/cons

  - by Ian Boyd

  I have a table in SQL Server, where i want inserts to be added to the end of the table (as opposed to a clustering key that would cause them to be inserted in the middle). This means I want the table clustered by some column that will constantly increase. This could be achieved by clustering on a datetime column: CREATE TABLE Things ( ... CreatedDate datetime DEFAULT getdate(), [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (CreatedDate) ) But I can't guaranteed that two Things won't have the same time. So my requirements can't really be achieved by a datetime column. I could add a dummy identity int column, and cluster on that: CREATE TABLE Things ( ... RowID int IDENTITY(1,1), [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (RowID) ) But you'll notice that my table already constains a timestamp column; a column which is guaranteed to be a monotonically increasing. This is exactly the characteristic I want for a candidate cluster key. So I cluster the table on the rowversion (aka timestamp) column: CREATE TABLE Things ( ... [timestamp] timestamp, CONSTRAINT [IX_Things] UNIQUE CLUSTERED (timestamp) ) Rather than adding a dummy identity int column (RowID) to ensure an order, I use what I already have. What I'm looking for are thoughts of why this is a bad idea; and what other ideas are better. Note: Community wiki, since the answers are subjective.

• xCode: iPhone Swipe Gesture crash

  - by David DelMonte

  I have an app that I'd like the swipe gesture to flip to a second view. The app is all set up with buttons that work. The swipe gesture though causes a crash ( “EXC_BAD_ACCESS”.). The gesture code is: - (void)handleSwipe:(UISwipeGestureRecognizer *)recognizer { NSLog(@"%s", __FUNCTION__); switch (recognizer.direction) { case (UISwipeGestureRecognizerDirectionRight): [self performSelector:@selector(flipper:)]; break; case (UISwipeGestureRecognizerDirectionLeft): [self performSelector:@selector(flipper:)]; break; default: break; } } and "flipper" looks like this: - (IBAction)flipper:(id)sender { FlashCardsAppDelegate *mainDelegate = (FlashCardsAppDelegate *)[[UIApplication sharedApplication] delegate]; [mainDelegate flipToFront]; } flipToBack (and flipToFront) look like this.. - (void)flipToBack { NSLog(@"%s", __FUNCTION__); BackViewController *theBackView = [[BackViewController alloc] initWithNibName:@"BackView" bundle:nil]; [self setBackViewController:theBackView]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.0]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES]; [frontViewController.view removeFromSuperview]; [self.window addSubview:[backViewController view]]; [UIView commitAnimations]; [frontViewController release]; frontViewController = nil; [theBackView release]; // NSLog (@" FINISHED "); } Maybe I'm going about this the wrong way... All ideas are welcome...

• Dynamically populated NSPopUpButtonCell menu in an NSOutlineView

  - by Mo

  I’m working with an NSOutlineView which has two columns. My dataSource supplies the outline view with a tree of items of a custom class which represents file types (that is, you initialise it with a UTI). The first column is the display name of the file type (e.g., “Source code”, “Interface Builder NIB document”, etc.). The second column is an NSPopUpButtonCell which is supposed to allow the user to pick a handler for the given document type (think of Xcode’s “File Types” preference pane, and you’re pretty much there). I can generate an NSMenu for a given item in the tree, populated with options based upon the Launch Services database entries for the UTI, complete with the relevant application icon and and so on. In fact, the menu itself works wonderfully, populated by way of NSPopUpButtonCellWillPopUpNotification. The problem is, try as I might, the cell when the menu isn’t popped up always contains precisely one of two things: either an empty string, or the default text for the cell, the former if the result of -handlerName on the item (the attribute assigned to the column) is non-nil, the latter otherwise. Moreover, I’m manually calling -selectItem: on the NSPopUpButtonCell instance, which just seems Wrong. In contrast, the left-hand column, which is just an NSTextFieldCell, everything just works (although granted, all it’s got to do is read the value from the item and present it). (Disclaimer: I’m fairly new at Cocoa UI stuff; I know Objective-C, and lots of other programming languages, but I’ve not a huge amount of experience of building Mac OS X UIs, so be gentle).
