• Which credentials should I put in for Google App Engine BulkLoader at development server?

  - by Hoang Pham

  Hello everyone, I would like to ask which kind of credentials do I need to put on for importing data using the Google App Engine BulkLoader class appcfg.py upload_data --config_file=models.py --filename=listcountries.csv --kind=CMSCountry --url=http://localhost:8178/remote_api vit/ And then it asks me for credentials: Please enter login credentials for localhost Here is an extraction of the content of the models.py, I use this listcountries.csv file class CMSCountry(db.Model): sortorder = db.StringProperty() name = db.StringProperty(required=True) formalname = db.StringProperty() type = db.StringProperty() subtype = db.StringProperty() sovereignt = db.StringProperty() capital = db.StringProperty() currencycode = db.StringProperty() currencyname = db.StringProperty() telephonecode = db.StringProperty() lettercode = db.StringProperty() lettercode2 = db.StringProperty() number = db.StringProperty() countrycode = db.StringProperty() class CMSCountryLoader(bulkloader.Loader): def __init__(self): bulkloader.Loader.__init__(self, 'CMSCountry', [('sortorder', str), ('name', str), ('formalname', str), ('type', str), ('subtype', str), ('sovereignt', str), ('capital', str), ('currencycode', str), ('currencyname', str), ('telephonecode', str), ('lettercode', str), ('lettercode2', str), ('number', str), ('countrycode', str) ]) loaders = [CMSCountryLoader] Every tries to enter the email and password result in "Authentication Failed", so I could not import the data to the development server. I don't think that I have any problem with my files neither my models because I have successfully uploaded the data to the appspot.com application. So what should I put in for localhost credentials? I also tried to use Eclipse with Pydev but I still got the same message :( Here is the output: Uploading data records.

• What file format can represent an uncompressed raster image at 48 or 64 bits per pixel?

  - by finnw

  I am creating screenshots under Windows and using the LockBits function from GDI+ to extract the pixel data, which will then be written to a file. To maximise performance I am also: Using the same PixelFormat as the source bitmap, to avoid format conversion Using the ImageLockModeUserInputBuf flag to extract the pixel data into a pre-allocated buffer This pre-allocated buffer (pointed to by BitmapData::Scan0) is part of a memory-mapped file (to avoid copying the pixel data again.) I will also be writing the code that reads the file, so I can use (or invent) any format I wish. However I would prefer to use a well-known format that existing programs (ideally web browsers) are able to read, because that means I can visually confirm that the images are correct before writing the code for the other program (that reads the image.) I have implemented this successfully for the PixelFormat32bppRGB format, which matches the format of a 32bpp BMP file, so if I extract the pixel data directly into the memory-mapped BMP file and prefix it with a BMP header I get a valid BMP image file that can be opened in Paint and most browsers. Unfortunately one of the machines I am testing on returns pixels in PixelFormat64bppPARGB format (presumably this is influenced by the video adapter driver) and there is no corresponding BMP pixel format for this. Converting to a 16, 24 or 32bpp BMP format slows the program down considerably (as well as being lossy) so I am looking for a file format that can use this pixel format without conversion, so I can extract directly into the memory-mapped file as I have done with the 32bpp format. What raster image file formats support 48bpp and/or 64bpp?

• InvokeRequired not reliable?

  - by marocanu2001

  InvalidOperationException: Cross-thread operation not valid: Control 'progressBar' accessed from a thread other than the thread it was created ... Now this is not a nice way to start a day! not even if it's a Monday! So you have seen this and already thought, come on, this is an old one, just ask whether InvokeRequired before calling the method in the control, something like this: if (progressBar.InvokeRequired) {           progressBar.Invoke  ( new MethodInvoker( delegate {  progressBar.Value = 50;    }) ) }else      progressBar.Value = 50;    Unfortunately this was not working the way I would have expected, I got this error, debugged and though in debugging the InvokeRequired had become true , the error was thrown on the branch that did not required Invoke. So there was a scenario where InvokeRequired returned false and still accessing the control was not on the right thread ... Problem was that I kept showing and hiding the little form showing the progressbar. The progressbar was updating on an event  , ProgressChanged and I could not guarantee the little form was loaded by the time the event was thrown. So , spotted the problem, if none of the parents of the control you try to modify is created at the time of the method invoking, the InvokeRequired returns true! That causes your code to execute on the woring thread. Of course, updating UI before the win dow was created is not a legitimate action either, still I would have expected a different error. MSDN: "If the control's handle does not yet exist, InvokeRequired searches up the control's parent chain until it finds a control or form that does have a window handle. If no appropriate handle can be found, the InvokeRequired method returns false. This means that InvokeRequired can return false if Invoke is not required (the call occurs on the same thread), or if the control was created on a different thread but the control's handle has not yet been created." Have  a look at InvokeRequired's implementation: public bool InvokeRequired {     get     {         HandleRef hWnd;         int lpdwProcessId;         if (this.IsHandleCreated)         {             hWnd = new HandleRef(this, this.Handle);         }         else         {             Control wrapper = this.FindMarshallingControl();             if (!wrapper.IsHandleCreated)             {                 return false; // <==========             }             hWnd = new HandleRef(wrapper, wrapper.Handle);         }         int windowThreadProcessId = SafeNativeMethods.GetWindowThreadProcessId(hWnd, out lpdwProcessId);         int currentThreadId = SafeNativeMethods.GetCurrentThreadId();         return (windowThreadProcessId != currentThreadId);     } } Here 's a good article about this and a workaround http://www.ikriv.com/en/prog/info/dotnet/MysteriousHang.html

• How to use JSF's h:selectBooleanCheckbox with h:dataTable to create one object per row?

  - by c0d3x

  I have a Facelets page with a h:dataTable. In each row of the h:dataTable there is a h:selectBooleanCheckbox. If the checkbox is selected a new Object should be created with the data out of the corresponding row. How do I do this? How to get the selected rows or their data in a backing bean? Or would it be better to do it with h:selectManyCheckbox?

• Configure Apache to use different Unix User Accounts (www-data) per Site.

  - by BrainCore

  An Apache 2.x Webserver with default configurations from the ubuntu/debian repositories will use the www-data unix account for apache2 processes handling web requests. Assuming that apache is serving two different sites (domain1.com and domain2.com), is it possible for apache to use unix user www-data1 when handling requests to domain1.com, and use unix user www-data2 when handling requests to domain2.com? The motivation is to isolate the code for each domain name from one another.

• Why is numpy's einsum faster than numpy's built in functions?

  - by Ophion

  Lets start with three arrays of dtype=np.double. Timings are performed on a intel CPU using numpy 1.7.1 compiled with icc and linked to intel's mkl. A AMD cpu with numpy 1.6.1 compiled with gcc without mkl was also used to verify the timings. Please note the timings scale nearly linearly with system size and are not due to the small overhead incurred in the numpy functions if statements these difference will show up in microseconds not milliseconds: arr_1D=np.arange(500,dtype=np.double) large_arr_1D=np.arange(100000,dtype=np.double) arr_2D=np.arange(500**2,dtype=np.double).reshape(500,500) arr_3D=np.arange(500**3,dtype=np.double).reshape(500,500,500) First lets look at the np.sum function: np.all(np.sum(arr_3D)==np.einsum('ijk->',arr_3D)) True %timeit np.sum(arr_3D) 10 loops, best of 3: 142 ms per loop %timeit np.einsum('ijk->', arr_3D) 10 loops, best of 3: 70.2 ms per loop Powers: np.allclose(arr_3D*arr_3D*arr_3D,np.einsum('ijk,ijk,ijk->ijk',arr_3D,arr_3D,arr_3D)) True %timeit arr_3D*arr_3D*arr_3D 1 loops, best of 3: 1.32 s per loop %timeit np.einsum('ijk,ijk,ijk->ijk', arr_3D, arr_3D, arr_3D) 1 loops, best of 3: 694 ms per loop Outer product: np.all(np.outer(arr_1D,arr_1D)==np.einsum('i,k->ik',arr_1D,arr_1D)) True %timeit np.outer(arr_1D, arr_1D) 1000 loops, best of 3: 411 us per loop %timeit np.einsum('i,k->ik', arr_1D, arr_1D) 1000 loops, best of 3: 245 us per loop All of the above are twice as fast with np.einsum. These should be apples to apples comparisons as everything is specifically of dtype=np.double. I would expect the speed up in an operation like this: np.allclose(np.sum(arr_2D*arr_3D),np.einsum('ij,oij->',arr_2D,arr_3D)) True %timeit np.sum(arr_2D*arr_3D) 1 loops, best of 3: 813 ms per loop %timeit np.einsum('ij,oij->', arr_2D, arr_3D) 10 loops, best of 3: 85.1 ms per loop Einsum seems to be at least twice as fast for np.inner, np.outer, np.kron, and np.sum regardless of axes selection. The primary exception being np.dot as it calls DGEMM from a BLAS library. So why is np.einsum faster that other numpy functions that are equivalent? The DGEMM case for completeness: np.allclose(np.dot(arr_2D,arr_2D),np.einsum('ij,jk',arr_2D,arr_2D)) True %timeit np.einsum('ij,jk',arr_2D,arr_2D) 10 loops, best of 3: 56.1 ms per loop %timeit np.dot(arr_2D,arr_2D) 100 loops, best of 3: 5.17 ms per loop The leading theory is from @sebergs comment that np.einsum can make use of SSE2, but numpy's ufuncs will not until numpy 1.8 (see the change log). I believe this is the correct answer, but have not been able to confirm it. Some limited proof can be found by changing the dtype of input array and observing speed difference and the fact that not everyone observes the same trends in timings.

• How can I make these images download on a seperate thread?

  - by Andy Barlow

  Hello!! I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really apreciated. Thank-you kindly. Andy Barlow private class CatalogAdapter extends ArrayAdapter { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

• Subterranean IL: Volatile

  - by Simon Cooper

  This time, we'll be having a look at the volatile. prefix instruction, and one of the differences between volatile in IL and C#. The volatile. prefix volatile is a tricky one, as there's varying levels of documentation on it. From what I can see, it has two effects: It prevents caching of the load or store value; rather than reading or writing to a cached version of the memory location (say, the processor register or cache), it forces the value to be loaded or stored at the 'actual' memory location, so it is then immediately visible to other threads. It forces a memory barrier at the prefixed instruction. This ensures instructions don't get re-ordered around the volatile instruction. This is slightly more complicated than it first seems, and only seems to matter on certain architectures. For more details, Joe Duffy has a blog post going into the details. For this post, I'll be concentrating on the first aspect of volatile. Caching field accesses To demonstrate this, I created a simple multithreaded IL program. It boils down to the following code: .class public Holder { .field public static class Holder holder .field public bool stop .method public static specialname void .cctor() { newobj instance void Holder::.ctor() stsfld class Holder Holder::holder ret }}.method private static void Main() { .entrypoint // Thread t = new Thread(new ThreadStart(DoWork)) // t.Start() // Thread.Sleep(2000) // Console.WriteLine("Stopping thread...") ldsfld class Holder Holder::holder ldc.i4.1 stfld bool Holder::stop call instance void [mscorlib]System.Threading.Thread::Join() ret}.method private static void DoWork() { ldsfld class Holder Holder::holder // while (!Holder.holder.stop) {} DoWork: dup ldfld bool Holder::stop brfalse DoWork pop ret} If you compile and run this code, you'll find that the call to Thread.Join() never returns - the DoWork spinlock is reading a cached version of Holder.stop, which is never being updated with the new value set by the Main method. Adding volatile to the ldfld fixes this: dupvolatile.ldfld bool Holder::stopbrfalse DoWork The volatile ldfld forces the field access to read direct from heap memory, which is then updated by the main thread, rather than using a cached copy. volatile in C# This highlights one of the differences between IL and C#. In IL, volatile only applies to the prefixed instruction, whereas in C#, volatile is specified on a field to indicate that all accesses to that field should be volatile (interestingly, there's no mention of the 'no caching' aspect of volatile in the C# spec; it only focuses on the memory barrier aspect). Furthermore, this information needs to be stored within the assembly somehow, as such a field might be accessed directly from outside the assembly, but there's no concept of a 'volatile field' in IL! How this information is stored with the field will be the subject of my next post.

• Flex HttpService POST limited to 543 Byte per Form field?

  - by motto

  Hi, I am getting a FaultEvent when trying to send form fields through HTTPService that contain more than 542 chars. Initializing the HttpService: httpServ = new HTTPService(); httpServ.method = 'POST'; httpServ.url = ENDPOINT_URL; //http://localhost:3001/ReportError.aspx httpServ.resultFormat = HTTPService.RESULT_FORMAT_TEXT; httpServ.contentType = HTTPService.CONTENT_TYPE_FORM; httpServ.addEventListener(ResultEvent.RESULT, OnErrorSent); httpServ.addEventListener(FaultEvent.FAULT, OnFault); Sending the request: var params:Object = {}; //params["stack"] = e.stackTrace.slice(0, 542); //length 542 = works //params["stack2"] = e.stackTrace.slice(1, 543); //length 542 = works (just to show that it's not about the content itself) params["stack3"] = e.stackTrace.slice(0, 543); //length 543 = fails I also seem to be able to create many form fields (with 542 length) so that it's not a limit of the request itself but of the form field: var params:Object = {}; params["stack"] = e.stackTrace.slice(0, 542); //length 542 params["stack2"] = e.stackTrace.slice(1, 543); //length 542 params["stack3"] = e.stackTrace.slice(2, 544); //length 542 // Length > 1600 chars The receiving party is an ASP.NET 4 site on the same domain and port. I hope someone already came across a similar restrictions or has some general advice on how to trace this problem down further. Thanks in advance.

• How can you toggle between two sets of values per data series in flot?

  - by Jedidja

  flot has built-in support for multiple data series (sample code) and also dual-axis (sample code). Assuming multiple data series (water, electricity, etc) that each have an amount (usage) and a dollar value (charge for that usage), what would the best way be to to use flot to display either the amount or dollar values for all the data series, while still supporting toggling display for each individual series? The idea is to send down all the data in one GET request and then let the client take care of everything else in Javascript. Ideally we could use triplets somehow {date, amount, charge}, and then possibly split that into two arrays for flot.

• Would this hack for per-object permissions in django work?

  - by Edward

  According to the documentation, a class can have the meta option permissions, described as such: Options.permissions Extra permissions to enter into the permissions table when creating this object. Add, delete and change permissions are automatically created for each object that has admin set. This example specifies an extra permission, can_deliver_pizzas: permissions = (("can_deliver_pizzas", "Can deliver pizzas"),) This is a list or tuple of 2-tuples in the format (permission_code, human_readable_permission_name). Would it be possible to define permissions at run time by: permissions = (("can_access_%s" % self.pk, / "Has access to object %s of type %s" % (self.pk,self.__name__)),) ?

• How can I include an external JavaScript file exactly once per partial view?

  - by AaronSieb

  I have a partial view (UserControl) that implements a simple pager in my Asp.Net MVC project. This pager needs access to a .js file that needs to be included exactly once, regardless of how many instances of the pager control are present on the parent page. I've tried to use Page.ClientScript.RegisterClientScriptInclude, but it had no effect (I assume because the code nugget was evaluated too late to impact the head control). Is there any simple alternative?

• CakePHP: Same model, set up per form validation rules?

  - by mwaterous

  I have a single model in CakePHP that has multiple forms on different pages of the site that I would like to validate differently even where the field name is the same - I have discovered that you can set 'on' to create|update which has been a handy discovery but I am wondering if there is any other way of explicitly declaring rules based on the form that was submitted? Just to rephrase for clarity, form a and form b contain fields of the same name, but if form a is submitted the fields in question should be validated differently than if they were submitted from form b. Possible?

So I want to do this: People is the action, string Height, string searchHigh, sting searchLow /Groups/People/Tall/searchHigh and this /Groups/People/Short/searchLow i map both and the first route works, but the second gets appended to the first when go to the short tab.

• is it possible to set per-file options for Nedit like you can do for emacs/vim

  - by Nathan Fellman

  With VIM or Emacs I can put comments in the file that will be VIM's settings for that file: /* * Local Variables: * mode: C * c-basic-offset: 4 * c-indentation-style: linux * indent-tabs-mode: nil * default-tab-width: 8 * fill-column: 125 * End: * * vim: et:sw=4:ts=8:si:cindent:cino=\:0,g0,(0: */ Can the same be done with Nedit?

• C# 5: At last, async without the pain

  - by Alex.Davies

  For me, the best feature in Visual Studio 11 is the async and await keywords that come with C# 5. I am a big fan of asynchronous programming: it frees up resources, in particular the thread that a piece of code needs to run in. That lets that thread run something else, while waiting for your long-running operation to complete. That's really important if that thread is the UI thread, or if it's holding a lock because it accesses some data structure. Before C# 5, I think I was about the only person in the world who really cared about asynchronous programming. The trouble was that you had to go to extreme lengths to make code asynchronous. I would forever be writing methods that, instead of returning a value, accepted an extra argument that is a "continuation". Then, when calling the method, I'd have to pass a lambda in to it, which contained all the stuff that needed to happen after the method finished. Here is a real snippet of code that is in .NET Demon: m_BuildControl.FilterEnabledForBuilding(     projects,     enabledProjects = m_OutOfDateProjectFinder.FilterNeedsBuilding(         enabledProjects,         newDirtyProjects =         {             // Mark any currently broken projects as dirty             newDirtyProjects.UnionWith(m_BrokenProjects);             // Copy what we found into the set of dirty things             m_DirtyProjects = newDirtyProjects;             RunSomeBuilds();         })); It's just obtuse. Who puts a lambda inside a lambda like that? Well, me obviously. But surely enabledProjects should just be the return value of FilterEnabledForBuilding? And newDirtyProjects should just be the return value of FilterNeedsBuilding? C# 5 async/await lets you write asynchronous code without it looking so stupid. Here's what I plan to change that code to, once we upgrade to VS 11: var enabledProjects = await m_BuildControl.FilterEnabledForBuilding(projects); var newDirtyProjects = await m_OutOfDateProjectFinder.FilterNeedsBuilding(enabledProjects); // Mark any currently broken projects as dirty newDirtyProjects.UnionWith(m_BrokenProjects); // Copy what we found into the set of dirty things m_DirtyProjects = newDirtyProjects; RunSomeBuilds(); Much easier to read! But how is this the same code? If we were on the UI thread, doesn't the UI thread have to block while FilterEnabledForBuilding runs? No, it doesn't, and that's the magic of the await keyword! It cuts your method up into its constituent pieces, much like I did manually with lambdas before. When you run it, only the piece up to the first await actually runs. The rest is passed to FilterEnabledForBuilding as a continuation, which will get called back whenever that method is finished. In the meantime, our thread returns, and can go back to making the UI responsive, or whatever else threads do in their spare time. This is actually a massive simplification, and if you're interested in all the gory details, and speed hacks that the await keyword actually does for you, I recommend Jon Skeet's blog posts about it.

• How to install Multiple ActiveX Controls per one step?

  - by Eugene

  My .ocx contains two ActiveX controls and I use both of them on one page. When user comes to page he gets two install confirmations for the same binary. After the first installation and page reload he gets one control displayed and “the website wants to run the following add-on...” yellow bar with control’s run confirmation for the other. I have only two possible solutions: Adding my CLSID’s to IE’s pre-approved control list, but I guess I cannot do it in the case of Non-Admin installation. Besides I consider this way as unreliable. Use the third control-container for hosting all other controls. It seems to my too complicated. Actually I’m not sure it can be done. Controls are used from the WEB, so I cannot use any administrative tools for installation. Is it possible to do all installation actions with one step without twice installation or run confirmation? Are there any “Best practices” for my case?
