  • The way to find out whole picture width in PGF (Latex)

    - by drasto
    I've got a latex macro that draws a picture using PGF and Tikz according to given parameters. The width of picture drawn depends on these parameters. PGF automatically calculates the resulting width of any picture drawn so the user does not have to set it explicitly(like for example when using latex build in picture environment). However I need to know the width of picture that will be drawn. Of cause I could calculate it as the PGF does but this is going to be quite some work(a lot of if statements...). Is there a way to ask PGF what is the width of picture that is to be drawn (some command I expect)? Either inside tikzpicture environment or just after it? Thanks for help.

  • zend framework 2 autentification using DbTable failure

    - by josepmra
    I have followed the zend instructions for implement my web Authentication using a database table. It's exactly the same code, but when render the page, the following exceptions appears: Zend\Authentication\Adapter\Exception\RuntimeException File: C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Authentication\Adapter\DbTable.php Mensaje: The supplied parameters to DbTable failed to produce a valid sql statement, please check table and column names for validity. produced by this other: Zend\Db\Adapter\Exception\InvalidQueryException File: C:\xampp\htdocs\pfc\vendor\ZF2\library\Zend\Db\Adapter\Driver\Mysqli\Statement.php Mensaje: Statement couldn't be produced with sql: SELECT `users`.*, (CASE WHEN `password` = ? THEN 1 ELSE 0 END) AS `zend_auth_credential_match` FROM `users` WHERE `mail` = ? Seems to be that Statement.php can not execute the sql of above, but I send the sql by phpmyadmin replacing the ? for strings and work ok. I am sure that $dbAdapter works ok also because I have tested it and the columns name are "mail" and "password". This in my code, also I put the $dbAdapter test code. $dbAdapter = new DbAdapter(array( //This DbAdapter Work ok sure!! 'driver' => 'Mysqli', 'database' => 'securedraw', 'username' => 'root', 'password' => '' )); $fp = function($name) use ($dbAdapter) { return $dbAdapter->driver->formatParameterName($name);}; $sql = 'SELECT * FROM ' . $qi('users') .

  • How to do validation on both client and server side for a service which is a store procedure(return a complex type)

    - by Tai
    Hi I am doing Silverlight 4 In my database, I have a store procedure(having two parameters) which returns rows (with extra fields). So i have to make a complex type for those rows on my Models. And Making a service to call that function import store procedure. The RIA will automatically create a matching Entity(to the complex type) and an operation for me. However, I don't know how to validation the parameters of the operation on both client and server side. For example, the parameter must be an integer only (and greater than 10) or datetime only. below is my xaml code. I am using DomainDataSource control and don't know how to validate the two field parameter.It has two TextBox to let the user types in the value of parameters. Plz help me, thank you <riaControls:DomainDataSource AutoLoad="False" d:DesignData="{d:DesignInstance my1:USPFinancialAccountHistory, CreateList=true}" Height="0" LoadedData="uSPFinancialAccountHistoryDomainDataSource_LoadedData" Name="uSPFinancialAccountHistoryDomainDataSource" QueryName="GetFinancialAccountHistoryQuery" Width="0" Margin="0,0,705,32"> <riaControls:DomainDataSource.DomainContext> <my:USPFinancialAccountHistoryContext /> </riaControls:DomainDataSource.DomainContext> <riaControls:DomainDataSource.QueryParameters> <riaControls:Parameter ParameterName="fiscalYear" Value="{Binding ElementName=fiscalYearTextBox, Path=Text}" /> <riaControls:Parameter ParameterName="fiscalPeriod" Value="{Binding ElementName=fiscalPeriodTextBox, Path=Text}" /> </riaControls:DomainDataSource.QueryParameters> </riaControls:DomainDataSource> <StackPanel Height="30" HorizontalAlignment="Left" Orientation="Horizontal" VerticalAlignment="Top"> <sdk:Label Content="Fiscal Year:" Margin="3" VerticalAlignment="Center" /> <TextBox Name="fiscalYearTextBox" Width="60" /> <sdk:Label Content="Fiscal Period:" Margin="3" VerticalAlignment="Center" /> <TextBox Name="fiscalPeriodTextBox" Width="60" /> <Button Command="{Binding Path=LoadCommand, ElementName=uSPFinancialAccountHistoryDomainDataSource}" Content="Load" Margin="3" Name="uSPFinancialAccountHistoryDomainDataSourceLoadButton" /> </StackPanel> <telerik:RadGridView ItemsSource="{Binding ElementName=uSPFinancialAccountHistoryDomainDataSource, Path=Data}" Name="uSPFinancialAccountHistoryRadGridView" Grid.Row="1" IsReadOnly="True" DataLoadMode="Asynchronous" AutoGenerateColumns="False" ShowGroupPanel="False"> <telerik:RadGridView.Columns> <telerik:GridViewDataColumn Header="Account Number" DataMemberBinding="{Binding AccountNumber}"/> <telerik:GridViewDataColumn Header="Department Number" DataMemberBinding="{Binding DepartmentNumber}"/> <telerik:GridViewDataColumn Header="Period code" DataMemberBinding="{Binding PeriodCode}" /> <telerik:GridViewDataColumn Header="Total Debit" DataMemberBinding="{Binding TotalDebit}" DataFormatString="{}{0:C2}"/> <telerik:GridViewDataColumn Header="Total Credit" DataMemberBinding="{Binding TotalCredit}" DataFormatString="{}{0:C2}"/> <telerik:GridViewDataColumn Header="Period Total" DataMemberBinding="{Binding PeriodTotal}" DataFormatString="{}{0:C2}"/> <telerik:GridViewDataColumn Header="Year To Date" DataMemberBinding="{Binding YearToDate}" DataFormatString="{}{0:C2}"/> </telerik:RadGridView.Columns> </telerik:RadGridView>

  • Ajax call from Bookmarklet

    - by Adam Haile
    I am trying to create a bookmarklet that, upon clicking, would request some information from the user (a url and a couple other fields in this case) and then send that data to a php page on my server and then display the result. I would like to do an Ajax call for this so that I don't actually redirect to the new page, just get the data but I assume I would run into the "Same Origin Policy" limitation of Ajax.... is there any known way of basically doing the same thing? Also, what would be the best way to pass the parameters? I already have a mechanism in place to recieve the parameters as a post message from a form...is there any way I could just reuse this?

  • php resize image

    - by haohan
    I have a class to read and output the image content, if $width is set, it will resize the image, and then output it. If I call the function like this $image-readImage('123.jpg'); , it can output the image file correctly, but when I call $image-readImage('123.jpg'); , it just display a black image with resized width & height. And I tried to replace the code from @imagejpeg($thumb, null, 100); to @imagejpeg($image, null, 100); will works~ - protected function readImage($fileName, $width = 0) { if ($width <= 0) { return @file_get_contents($this-destination . '/' . $fileName); } else { $imageSize = @getimagesize($this-destination . '/' . $fileName); $actualWidth = $imageSize[0]; $actualHeigth = $imageSize[1]; if ($actualWidth <= $width) { return @file_get_contents($this-destination . '/' . $fileName); } $height = (100 / ($actualWidth / $width)) * .01; $height = @round($actualHeigth * $height); $image = @imagecreatefromjpeg($this-destination .

  • Strange \n in base64 encoded string in Ruby

    - by intellidiot
    The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

  • ASP.NET MVC F# controller action ignoring parameter

    - by Matt H
    Hi. I have a C# ASP.NET MVC project but my controllers are written in F#. For some reason, the following code doesn't work properly. namespace MvcApplication8.Controllers open System.Web.Mvc [<HandleError>] type ImageController() = inherit Controller() member x.Index (i : int) : ActionResult = x.Response.Write i x.View() :> ActionResult The parameter of the action is seemingly ignored. http://localhost:56631/Image/Index/1 = The parameters dictionary contains a null entry for parameter 'i' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Index(Int32)' in 'MvcApplication8.Controllers.ImageController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters The controller otherwise works fine. I know that plenty of people have written F# mvc code, so, any ideas where I'm going wrong?

To make a parameter optional its type should be either a reference type or a Nullable type. Parameter name: parameters Any suggestion...

  • What are the default values for arch and code options when using nvcc?

    - by Auron
    When compiling your CUDA code, you have to select for which architecture your code is being generated. nvcc provides two parameters to specify this architecture, basically: arch specifies the virtual arquictecture, which can be compute_10, compute_11, etc. code specifies the real architecture, which can be sm_10, sm_11, etc. So a command like this: nvcc x.cu -arch=compute_13 -code=sm_13 Will generate 'cubin' code for devices with 1.3 compute capability. Please correct me if I'm wrong. Which I would like to know is which are the default values for these two parameters? Which is the default architecture that nvcc uses when no value for arch or code is specified?

  • Code Golf: Shortest Turing-complete interpreter.

    - by ilya n.
    I've just tried to create the smallest possible language interpreter. Would you like to join and try? Rules of the game: You should specify a programming language you're interpreting. If it's a language you invented, it should come with a list of commands in the comments. Your code should start with example program and data assigned to your code and data variables. Your code should end with output of your result. It's preferable that there are debug statements at every intermediate step. Your code should be runnable as written. You can assume that data are 0 and 1s (int, string or boolean, your choice) and output is a single bit. The language should be Turing-complete in the sense that for any algorithm written on a standard model, such as Turing machine, Markov chains, or similar of your choice, it's reasonably obvious (or explained) how to write a program that after being executred by your interpreter performs the algorithm. The length of the code is defined as the length of the code after removal of input part, output part, debug statements and non-necessary whitespaces. Please add the resulting code and its length to the post. You can't use functions that make compiler execute code for you, such as eval(), exec() or similar.

    I am working on SportsStore example on chapter 4 from the following book and getting stuck... Pro Asp.net mvc framework I get the following error: The current request for action 'List' on controller type 'ProductsController' is ambiguous between the following action methods: System.Web.Mvc.ViewResult List() on type WebUI.Controllers.ProductsController System.Web.Mvc.ViewResult List(Int32) on type WebUI.Controllers.ProductsController ..

  • How to Obtain Data to Pre-Populate Forms.

    - by Stan
    The objective is to have a form reflect user's defined constraints on a search. At first, I relied entirely upon server-side scripting to achieve this; recently I tried to shift the functionality to JavaScript. On the server side, the search parameters are stored in a ColdFusion struct which makes it particularly convenient to have the data JSON'ed and sent to the client. Then it's just a matter of separately iterating over 'checkable' and text fields to reflect the user's search parameters; jQuery proved to be exceptionally effective in simplifying the workload. One observable difference lies in performance. The second method appeared to be somewhat slower and didn't work in IE8. Evidently, the returned JSON'ed struct was seen as an empty object. I'm sure it can be fixed, though before spending any more time with it, I'm curious to hear how others would approach the task. I'd gladly appreciate any suggestions. --Stan

  • Spring WS & Validator interceptor

    - by mada
    I have a endpoint mapping a webservice which is used to insert in the dabatabase some keywords: @Transactional(readOnly = false,isolation= Isolation.SERIALIZABLE) public Source saveKW(...). The input is a request. I would like to add an interceptor on the method in order to validate the parameters. this one will read some values from the DB. i would like that this interceptor is EMBED in the transaction declared for the endpoint (or this opposite). In other words, i want them to be in the same transaction. Ideally im looking for something like this with annotation: @Transactional(readOnly = false,isolation= Isolation.SERIALIZABLE) @validator("KeyWordValidaor.class") public Source saveKW(...) where KeyWordValidaor will be class validating the parameters. Have you any idea or short examples to implements this like this way or in a other real way?

  • Using Hidden Markov Model for designing AI mp3 player

    - by Casper Slynge
    Hey guys. Im working on an assignment, where I want to design an AI for a mp3 player. The AI must be trained and designed with the use of a HMM method. The mp3 player shall have the functionality of adapting to its user, by analyzing incoming biological sensor data, and from this data the mp3 player will choose a genre for the next song. Given in the assignment is 14 samples of data: One sample consist of Heart Rate, Respiration, Skin Conductivity, Activity and finally the output genre. Below is the 14 samples of data, just for you to get an impression of what im talking about. Sample HR RSP SC Activity Genre S1 Medium Low High Low Rock S2 High Low Medium High Rock S3 High High Medium Low Classic S4 High Medium Low Medium Classic S5 Medium Medium Low Low Classic S6 Medium Low High High Rock S7 Medium High Medium Low Classic S8 High Medium High Low Rock S9 High High Low Low Classic S10 Medium Medium Medium Low Classic S11 Medium Medium High High Rock S12 Low Medium Medium High Classic S13 Medium High Low Low Classic S14 High Low Medium High Rock My time of work regarding HMM is quite low, so my question to you is if I got the right angle on the assignment. I have three different states for each sensor: Low, Medium, High. Two observations/output symbols: Rock, Classic In my own opinion I see my start probabilities as the weightened factors for either a Low, Medium or High state in the Heart Rate. So the ideal solution for the AI is that it will learn these 14 sets of samples. And when a users sensor input is received, the AI will compare the combination of states for all four sensors, with the already memorized samples. If there exist a matching combination, the AI will choose the genre, and if not it will choose a genre according to the weightened transition probabilities, while simultaniously updating the transition probabilities with the new data. Is this a right approach to take, or am I missing something ? Is there another way to determine the output probability (read about Maximum likelihood estimation by EM, but dont understand the concept)? Best regards, Casper

  • C++ Ambiguous call to Overloaded Function (const variety)

    - by Joe
    After researching this online, I've only found solutions that don't apply to my problem, so please bear with me. Code snippet: typedef my_map_t<int const *, float> _test; my_map_t::const_iterator not_found = my_map_t::end(); if (_test.find(&iKeyValue) == not_found) { _test[iKeyValue] = 4 + 5; // not the actual code, but here for simplicity } The compiler complains that there's an ambiguous call to my_map_t::end(). This makes sense, because the only difference is the return type. Output: error C2668: 'std::_Tree<_Traits>::end' : ambiguous call to overloaded function Normally you can disambiguate the call by casting the parameters, but end() has no parameters. Any ideas?

  • Threads, Sockets, and Designing Low-Latency, High Concurrency Servers

    - by lazyconfabulator
    I've been thinking a lot lately about low-latency, high concurrency servers. Specifically, http servers. http servers (fast ones, anyway) can serve thousands of users simultaneously, with very little latency. So how do they do it? As near as I can tell, they all use events. Cherokee and Lighttpd use libevent. Nginx uses it's own event library performing much the same function of libevent, that is, picking a platform optimal strategy for polling events (like kqueue on *bsd, epoll on linux, /dev/poll on Solaris, etc). They all also seem to employ a strategy of multiprocess or multithread once the connection is made - using worker threads to handle the more cpu intensive tasks while another thread continues to listen and handle connections (via events). This is the extent of my understanding and ability to grok the thousand line sources of these applications. What I really want are finer details about how this all works. In examples of using events I've seen (and written) the events are handling both input and output. To this end, do the workers employ some sort of input/output queue to the event handling thread? Or are these worker threads handling their own input and output? I imagine a fixed amount of worker threads are spawned, and connections are lined up and served on demand, but how does the event thread feed these connections to the workers? I've read about FIFO queues and circular buffers, but I've yet to see any implementations to work from. Are there any? Do any use compare-and-swap instructions to avoid locking or is locking less detrimental to event polling than I think? Or have I misread the design entirely? Ultimately, I'd like to take enough away to improve some of my own event-driven network services. Bonus points to anyone providing solid implementation details (especially for stuff like low-latency queues) in C, as that's the language my network services are written in.

  • Function that prints something to std::ostream and returns std::ostream?

    - by dehmann
    I want to write a function that outputs something to a ostream that's passed in, and return the stream, like this: std::ostream& MyPrint(int val, std::ostream* out) { *out << val; return *out; } int main(int argc, char** argv){ std::cout << "Value: " << MyPrint(12, &std::cout) << std::endl; return 0; } It would be convenient to print the value like this and embed the function call in the output operator chain, like I did in main(). It doesn't work, however, and prints this: $ ./a.out 12Value: 0x6013a8 The desired output would be this: Value: 12 How can I fix this? Do I have to define an operator<< instead? UPDATE: Clarified what the desired output would be. UPDATE2: Some people didn't understand why I would print a number like that, using a function instead of printing it directly. This is a simplified example, and in reality the function prints a complex object rather than an int.

  • Encoding h.264 with libavcodec/x264

    - by Leviathan
    I am attempting to encode video using libavcodec/libavformat. I'm trying to change the standard output-example.c from ffmpeg source. The AVI file is created on the disk, but the only sound is encoded. I tried adding a lot of options for x264 from here. All the other codecs works fine, mpeg2, mpeg4, mjpeg, xvid. In addition to specifying the parameters x264, I also set the codec to AVOutputFormat structure. That's all I've done. AVOutputFormat *pOutFormat; // in header file av_register_all(); AVCodec *codec = avcodec_find_encoder_by_name("libx264"); pOutFormat = guess_format("avi", NULL, NULL); pOutFormat->video_codec = codec->id; The debug output of my application: Output #0, mp4, to 'D:\1.avi': Stream #0.0: Video: libx264, yuv420p, 320x240, q=10-51, 500 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: aac, 44100 Hz, 1 channels, s16, 128 kb/s [libx264 @ 0x694010]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x694010]bitrate tolerance too small, using .01 [libx264 @ 0x694010]profile Main, level 2.0 [libx264 @ 0x694010]frame I:150 Avg QP:14.76 size: 2534 [libx264 @ 0x694010]mb I I16..4: 75.9% 0.0% 24.1% [libx264 @ 0x694010]final ratefactor: 17.57 [libx264 @ 0x694010]coded y,uvDC,uvAC intra: 42.7% 92.4% 47.4% [libx264 @ 0x694010]i16 v,h,dc,p: 11% 14% 2% 73% [libx264 @ 0x694010]i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 21% 18% 29% 5% 8% 10% 3% 3% 2% [libx264 @ 0x694010]kb/s:506.79

  • Getting PCM values of WAV files

    - by user2431088
    I have a .wav mono file (16bit,44.1kHz) and im using this code below. If im not wrong, this would give me an output of values between -1 and 1 which i can apply FFT on ( to be converted to a spectrogram later on). However, my output is no where near -1 and 1. This is a portion of my output 7.01214599609375 17750.2552337646 8308.42733764648 0.000274658203125 1.00001525878906 0.67291259765625 1.3458251953125 16.0000305175781 24932 758.380676269531 0.0001068115234375 This is the code which i got from another post Edit 1: public static Double[] prepare(String wavePath, out int SampleRate) { Double[] data; byte[] wave; byte[] sR = new byte[4]; System.IO.FileStream WaveFile = System.IO.File.OpenRead(wavePath); wave = new byte[WaveFile.Length]; data = new Double[(wave.Length - 44) / 4];//shifting the headers out of the PCM data; WaveFile.Read(wave, 0, Convert.ToInt32(WaveFile.Length));//read the wave file into the wave variable /***********Converting and PCM accounting***************/ for (int i = 0; i < data.Length; i += 2) { data[i] = BitConverter.ToInt16(wave, i) / 32768.0; } /**************assigning sample rate**********************/ for (int i = 24; i < 28; i++) { sR[i - 24] = wave[i]; } SampleRate = BitConverter.ToInt16(sR, 0); return data; }

  • Issue using GAE appcfg.py

    - by JustSmith
    I get nothing out of appcfg.py besides the default output. I'm trying to upload some data to my development project with no luck at at all. From the instructions on the Google App Engine page the steps are as follows: Edit app.yaml update with appcfg.py make upload script upload with appcfg.py After step one I try to run the update and it never shows any success. The following commands product the same output: appcfg.py appcfg.py update appDir appcfg.py update appDir/ appcfg.py update /appDir If i try to follow the instructions from the appcfg.py output and type help upload and get: "help <action>" I get a response from the system, This command is not supported by the help utility. Try "update /?". cause I'm calling the system help command. If I use the command appcfg.py help upload I get the same result as just typing appcfg.py Can someone show me examples of the syntax to update the dev site, upload data to it and get appcfg.py to actually give help on its commands? Also I'm just assuming that the upload script and the .csv file that are being uploaded are in they myApp directory. Appreciate any help,

  • Loop with a while

    - by ookla
    Very basic question.. but I'm missing the point.. I have this data on my table: ID SITEID SECTION 1 1 posts 2 2 posts 3 1 aboutme 4 1 contact 5 2 questions The output is an array. I can't change it. I want to make this output on php with a single for loop with that array: <h1> sections for site 1 </h1> posts aboutme contact <h1>sections for site 2 </h1> posts questions I'm trying to do something like this, where $sectionsArray is my output. And I want to check if siteid is the same, then make a loop.. for ($j=0;$j<sizeof($sectionsArray);$j++) { while (siteid==1){ echo "<h1>'.$sectionsArray['siteid'].'</h1>'; } echo "<A href='section.php?id='.$sectionsArray['id'].' '">'.$sectionsArray['section'].'</a>; } But I don't get the logic of "grouping" the results with a while.. INSIDE a loop. Any light will be welcome. Thanks
