  • Is there a blog tool with support for tagging posts, only displaying posts with certain combinations

    - by Philip
    What I want: A blog. I can tag posts, e.g. "A" or "B" or "all," and then you can either 1) click to only view posts tagged "A" or "all" or 2) even more ideally, I can set it so you automatically see posts tagged "A" or "all" when you log in. LaTeX support--I can type in LaTeX in the editor and it will show the math properly. No anonymous anything--must sign up and be logged in to view and comment Not as important, but convenient: Admin controls, e.g. detailed statistics, see who posts or views what when, control who posts / views, etc. Hosting: Ideally, if there's some software I can install on "my" own server, that would be ideal. But if we can't host it, it'd still be good to find some free (or maybe even paid) service elsewhere that would host the blog if it provided those tools. Any thoughts? I have no experience with this. Thanks!

  • Missing audio and problems playing FLV video converted from 720p .mov file with FFMPEG

    - by undefined
    I have some .mov video files recorded from a JVC GC-FM1 HD video camera in 720p mode. I have FFMPEG running on a Linux box that I upload files to and have them encoded into FLV format. The video appears to be encoding ok but there is no audio in the resulting FLV file and when I play it back in Flash Player in a browser or on Adobe Media Player, the video pauses at the start. It appears that Adobe Media Player waits for the progress bar to reach the end of the video before starting the playback - i.e. the video will load, the picture pauses, the progress bar seeks to the end as if the video was playing then when it reaches the end the video picture starts. There is no audio on the video. I am noticing this in the video player I have built with Flash 8 using an FLVPlayback component and attached seekBar. The seek bar will start moving as if the video is playing but the picture remains paused. Here are some outputs from my FFMPEG log and the command I am using to encode the video - my FFMPEG command called from PHP - $cmd = 'ffmpeg -i ' . $sourcelocation.$filename.".".$fileext . ' -ab 96k -b 700k -ar 44100 -s ' . $target['width'] . 'x' . $target['height'] .

  • How to make MAMP PRO / XAMPP secure enough to serve as production webserver? Is it possible?

    - by Andrei
    Hi, my task is to setup a MAMP webserver for our website in the easiest way so it can be managed by my colleagues without experience in server administration. MAMP PRO is an excellent solution, but some guys don't suggest to use it for serving external requests. Could you explain why it is bad (in details if possible) and how to make it secure enough to be a full-scale and not-only-local webserver? Is there a better solution? Update There is a discussion on the MAMP website. XAMPP developers say that one can make their product secure: The default configuration is not good from a securtiy point of view and it's not secure enough for a production environment - please don't use XAMPP in such environment. Since LAMPP 0.9.5 you can make your XAMPP installation secure by calling »/opt/lampp/lampp security«. Could you comment it?

  • apache performance improvements and maxclients

    - by updog
    I know this has been asked a few (thousand) times around the internet but I was hoping someone whose in the know might be able to comment on my particular setup. I have a web server hosting one site (php/codeigniter) with a wordpress blog in a sub directory. The server has 2GB RAM, 3GHz CPU and I have offloaded the static assets to CloudFlare which is has reduced bandwidth for the actual server by almost 75%. The problem I have is when an email campaign is sent out that links to the site or blog, it slows down. Below is my settings in apache2.conf. Average apache process size is 80M and there is 1.5GB available for apache. <IfModule mpm_prefork_module> StartServers 8 MinSpareServers 5 MaxSpareServers 20 MaxClients 20 MaxRequestsPerChild 2000 </IfModule> I have already setup and installed apc and built some caching into the site and used w3totalcache on the blog. The number of concurrent users is around 2-300 when there is a campaign, are there any further optimisations before

  • ZendX_JQuery dialogContainer usage

    - by Kalle Johansson
    Hi ! I'm aming to make use of the ZendX_JQuery dialogContainer view helper, in order to produce a modal window, were users can input specified information(for example send a message). I'm trying to use the dialogContainer view helper in this fashion. First of, include the ZendX library in the applications library folder. Secondly, include the following row in the initViewHelper method within the Bootstrap.php file "$view-addHelperPath('ZendX/JQuery/View/Helper/', 'ZendX_JQuery_View_Helper');" third, adding the following conditional enabling of js in the layout.phtml "<?php if($this->jQuery()->isEnabled()){ $this->jQuery()->setLocalPath($this->baseUrl() .'/js/jquery/js/jquery-1.4.2.min.js') ->setUiLocalPath($this->baseUrl() .'/js/jquery/js/jquery-ui-1.8.custom.min.js') ->addStylesheet($this->baseUrl() .'/js/jquery/css/ui-lightness/jquery-ui-1.8.custom.css'); echo $this->jQuery(); } ?>" fourth, creating my Application_Form_JQueryForm extending ZendX_JQuery_Form "<?php class Application_Form_JQueryForm extends ZendX_JQuery_Form { private $form; public function init() { $this->form = $this->setAction(Zend_Controller_Front::getInstance()->getBaseUrl() . '/index/index') ->setMethod('post'); $this->form->setDecorators(array( 'FormElements', 'Form', array ('DialogContainer', array( 'id' => 'tabContainer', 'style' => 'width: 600px;', 'title' => 'Send a private message to Kalle', 'JQueryParams' => array( 'tabPosition' => 'top', ), )), )); $topic = new Zend_Form_Element_Text('topic'); $topic->setValue('topic') ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $textarea = new Zend_Form_Element_Textarea('textarea'); $textarea->setValue('post a comment') ->setAttribs(array( 'rows' => 4, 'cols' => 20 )) ->setRequired(true) ->setValidators(array('validators' => array( 'validator' => 'StringLength', 'options' => array(1,15) ))) ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('HtmlTag', array('tag' => 'dl')))); $submit = new Zend_Form_Element_Submit('submit'); $submit->setLabel('Send your comment') ->setDecorators(array( 'ViewHelper', 'Description', 'Errors', array('Description', array('escape' => false, 'tag' => 'span')), array('HtmlTag', array('tag' => 'dl')))) ->setDescription('or <a href="/index/index/send/false">Cancel</a>'); $this->form->addElements(array($topic, $textarea, $submit)); } }" This form is then instanciated in the controllers action method, and called in the view. And so to the problem of mine, no matter what i try, in order to for instance set, the width of the dialogContainer or any other parameter (color, css, height, so on and so forth), this being in the JQueryForm's setDecorator part for the form, i can't seem to get any change whatsoever in the resulting modal when called in the view, any help in the proper direction would be greatly appreciated Thanks in advance, Kalle Johansson

  • Looking for a very bare and basic blog system?

    - by Shedo Chung-Hee Surashu
    Does anyone know of a user-hosted blog which can be an alternative to WordPress only, it should only have the bare necessities of a blog. I'll just take it from there. It should only have the following: Admin Account (for posting, editing, etc) Archive System Posting System with character limitation (For the Read More links.) Accept Comments from other users (only requires the user's name and email and / or website, then the actual comment). Pages (Allows me to create pages for custom content.) The reason I want this is because WordPress is already too bloated up that there are a ton of features that I don't need. I'd mostly be satisfied with a blogging system that has the above feature-set and I'll just work my way to add my own feature as I require it along the way.

  • Create user in Oracle 11g with same priviledges as in Oracle 10g XE

    - by Álvaro G. Vicario
    I'm a PHP developer (not a DBA) and I've been working with Oracle 10g XE for a while. I'm used to XE's simplified user management: Go to Administration/ Users/ Create user Assign user name and password Roles: leave the default ones (connect and resource) Privileges: click on "Enable all" to select the 11 possible ones Create This way I get a user that has full access to its data and no access to everything else. This is fine since I only need it to develop my app. When the app is to be deployed, the client's DBAs configure the environment. Now I have to create users in a full Oracle 11g server and I'm completely lost. I have a new concept (profiles) and there're like 20 roles and hundreds of privileges in various categories. What steps do I need to complete in Oracle Enterprise Manager in order to obtain a user with the same privileges I used to assign in XE? ==== UPDATE ==== I think I'd better provide a detailed explanation so I make myself clearer. This is how I create a user in 10g XE: Roles: [X] CONNECT [X] RESOURCE [ ] DBA Direct Asignment System Privileges: [ ] CREATE DATABASE LINK [ ] CREATE MATERIALIZED VIEW [ ] CREATE PROCEDURE [ ] CREATE PUBLIC SYNONYM [ ] CREATE ROLE [ ] CREATE SEQUENCE [ ] CREATE SYNONYM [ ] CREATE TABLE [ ] CREATE TRIGGER [ ] CREATE TYPE [ ] CREATE VIEW I click on Enable All and I'm done. This is what I'm asked when doing the same in 11g: Profile: (*) DEFAULT ( ) WKSYS_PROF ( ) MONITORING_PROFILE Roles: CONNECT: [ ] Admin option [X] Default value Edit List: AQ_ADMINISTRATOR_ROLE

  • What is the difference in RAM speeds?

    - by jasondavis
    I am building a new PC with the intel i7-930 processor. I am wanting to use 12gb of RAM for it (6x2gb sticks). Here is some of the RAM I am looking at G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit Desktop 2 of these 3 stick kits. They are rated at 1600 however some of the user reviews on that product say they xcould not get it to run at 1600 and the supplier who makes the RAM made a comment that "I7 doesn't support over DDR3 1066" So I am curious, I do not know much about this, I know the more GB of RAM the better but as for the speeds, I am not sure how much of a difference it makes. So can someone explain to me what the difference in performance may be based on speeds of 1200 vs 1600 ram?

  • How to protect comments in Microsoft Word

    - by TestSubject528491
    I have inserted personal comments into a Word document, which I am distributing to other authors. How do I send them the file without them being able to see my comments? I can "hide" comments by going to the Review ribbon and deselecting Comments under Show Markup, but then when I close and reopen the file, the comment reappears. The same thing happens when I choose Final instead of Final Showing Markup. Is there a way to make comments only visible to the author by whom they were written?

  • OpenVPN vs. IPSec - Pros and Cons, what to use?

    - by jens
    interestingly I have not found any good searchresults when searching for "OpenVPN vs IPSec": I need to setup a private LAN over an untrusted network. And as far as I know, both approaces seem to be valid. But I do not know which one is better. I would be very thankfull If you can list the pro's and con's of both approaches and maybe your suggestions and experiences what to use. Update (Regarding the comment/question): In my concrete case the goal is to have any number of Servers (with static IPs) be connected transparently with each other. But a small portion of "dynamic clients like road warriors" (with dynamic IPs) should also be able to connect. The main goal is however having a "transparent secure network" run top of untrusted network. I am quite a newbie so I do not know how to correctly interprete "1:1 Point to Point Connections" = The solution should support Broadcasts and all that stuff so it is a fully functional network... Thank you very much!! Jens

  • Dependency Properties and Data Context in Silverlight 3

    - by Noam
    Hello, I am working with Silverlight 3 beta, and am having an issue. I have a page that has a user control that I worte on it. The user control has a dependency property on it. If the user control does not define a data context (hence using the parent's data context), all works well. But if the user control has its own data context, the dependency property's OnPropertyChanged method never gets called. Here is a sample: My Main Page: <UserControl x:Class="TestDepProp.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:app="clr-namespace:TestDepProp" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="400" Height="100"> <Grid x:Name="LayoutRoot" Background="White"> <Border BorderBrush="Blue" BorderThickness="3" CornerRadius="3"> <StackPanel Orientation="Horizontal"> <StackPanel Orientation="Vertical"> <TextBlock Text="Enter text here:" /> <TextBox x:Name="entryBlock" Text="{Binding Data, Mode=TwoWay}"/> <Button Content="Go!" Click="Button_Click" /> <TextBlock Text="{Binding Data}" /> </StackPanel> <Border BorderBrush="Blue" BorderThickness="3" CornerRadius="3" Margin="5"> <app:TestControl PropOnControl="{Binding Data}" /> </Border> </StackPanel> </Border> </Grid> </UserControl> Main Page code: using System.Windows; using System.Windows.Controls; namespace TestDepProp { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); MainPageData data = new MainPageData(); this.DataContext = data; } private void Button_Click(object sender, RoutedEventArgs e) { int i = 1; i++; } } } Main Page's data context: using System.ComponentModel; namespace TestDepProp { public class MainPageData:INotifyPropertyChanged { string _data; public string Data { get { return _data; } set { _data = value; if (PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs("Data")); } } public MainPageData() { Data = "Initial Value"; } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } } Control XAML: <UserControl x:Class="TestDepProp.TestControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:app="clr-namespace:TestDepProp" > <Grid x:Name="LayoutRoot" Background="White"> <StackPanel Orientation="Vertical" Margin="10" > <TextBlock Text="This should change:" /> <TextBlock x:Name="ControlValue" Text="Not Set" /> </StackPanel> </Grid> </UserControl> Contol code: using System.Windows; using System.Windows.Controls; namespace TestDepProp { public partial class TestControl : UserControl { public TestControl() { InitializeComponent(); // Comment out next line for DP to work DataContext = new MyDataContext(); } #region PropOnControl Dependency Property public string PropOnControl { get { return (string)GetValue(PropOnControlProperty); } set { SetValue(PropOnControlProperty, value); } } public static readonly DependencyProperty PropOnControlProperty = DependencyProperty.Register("PropOnControl", typeof(string), typeof(TestControl), new PropertyMetadata(OnPropOnControlPropertyChanged)); private static void OnPropOnControlPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { TestControl _TestControl = d as TestControl; if (_TestControl != null) { _TestControl.ControlValue.Text = e.NewValue.ToString(); } } #endregion PropOnControl Dependency Property } } Control's data context: using System.ComponentModel; namespace TestDepProp { public class MyDataContext : INotifyPropertyChanged { #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion } } To try it out, type something in the text box, and hit the Go button. Comment out the data context in the controls code to see that it starts to work. Hope someone has an idea as to what is going on.

  • How to mount /tmp in /mnt on EC2?

    - by Claudio Poli
    I was wondering what is the best way to mount the /tmp endpoint in the ephemeral storage /mnt on an EC2 instance and give the ubuntu user default write permissions. Some suggest editing /etc/rc.local this way: mkdir -p /mnt/tmp && mount --bind -o nobootwait /mnt/tmp /tmp However that doesn't work for me (files differs). I tried editing the default fstab entry: /dev/xvdb /mnt auto defaults,nobootwait,comment=cloudconfig 0 2 replacing /mnt with /tmp and and giving it a umask=0777, however it doesn't work because of cloudconfig. I'm using Ubuntu 12.04. Thanks.

  • USB Thumb Drive not recognized in Hyper-V Manager

    - by Vazgen
    I have the free, standalone core Hyper-V Server 2012 running on my physical machine. I set up remote management from my Windows 8 client. When I proceed to create a virtual machine I would like to install the OS from a usb thumb drive but it is not recognized in Hyper-V Manager on my client (when the USB is plugged into the physical server) nor is it recognized in Server Manager under File and Storage Services Volumes Is there a role needed to recognize external usb flash drives? Because I think this standalone version is just core Hyper-V role and that's it... but this is such a basic functionality. Can anybody comment.

  • The weirdest css issue I have ever seen

    - by jasondavis
    Below I have 2 css codes for a div, please note that the first one does not even have a div on the page or ANYTHING with it's name on it. I can also rename it to anything. Now where the weird part comes in. The second bit of code below has a width of 520px, the only way that the div on the page will be 520px is if I leave the css code thats above that one, the 1st one with no existing div on the page HAS to be on the page for the second css code to work, At first I thought it has to be a browser caching issue, so I clear my cache and that does nothing, I then try 2 other browsers and they all have the same result. I add the 1st bit of code into the page and the second bit works, I take the first bit away and the second bit does not work. AM i overlooking something here? .commentwrappsdfsde2{width:950px;margin:0 0;padding:0;} .commentwrapper{width:520px;margin-right:auto;margin-left:auto;} Here is the whole page code <style> <!-- css for user photos--> div.imageSub img.female { border-top: 1px solid #FF3399; } div.imageSub img.male { border-top: 1px solid #3399FF; } div.imageSub img { z-index: 1; margin: 0; display: block; } div.imageSub div { position: relative; margin: -15px 0 0; padding: 5px; height: 5px; line-height: 4px; text-align: center; overflow: hidden; font-family:Trebuchet MS,Helvetica,sans-serif; font-size:12px; font-weight: bold; } div.imageSub div.blackbg { z-index: 2; background-color: #000; -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)"; filter: alpha(opacity=70); opacity: 0.5; } div.imageSub div.label { z-index: 3; color: white; } <!-- end photo block--> /* Comments */ .commentwrappsdfsde2{width:950px;margin:0 0;padding:0;} .commentwrapper{width:520px;margin-right:auto;margin-left:auto;} #comments ol.commentlist li { list-style-type:none; padding:20px; background:none; } #comments ol.commentlist li.thread-even { background:#f6f6f6; border-top:1px solid #e3e3e3; border-bottom:1px solid #e3e3e3; } #comments ul.children li ul.children,#comments .commentlist{padding:0;} </style> <div class="commentwrapper"> <div id="comments"> <ol class="commentlist"> <li class="comment thread-even " > Comment 1 </li> </ol> </div> </div>

  • Apache disable DNS lookups

    - by odeceixe
    I'm using Debian 4.3.2-1 and Apache 2 on my production server. Watching the logs, I noticed Apache is resolving client's hostnames even with HostnameLookups Off in apache2.conf. I want to avoid these lookups so I'm guessing Apache is making this DNS query because I have mod_authz_host enabled. When I try to unlink this module, I get several modules complaining because they use the Order directive. How is the clean way to go? Should I comment all Order directives like Order allow,deny Deny from all Is this the only way to stop Apache from making DNS requests? I would like to deny access to .htaccess files and some rules like that.

  • Layout does not show up after Activity launch

    - by Peter
    I have an activity which invokes an onItemClick and launches another activity. This activity has a static layout(for testing purposes), but only thing I see is black(I even set the text color to white to check it out). My listener list.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { //create new intent Intent item = new Intent(getApplicationContext(), Item.class); // Close all views before launching logged //item.putExtra("name", ((TextView)arg1).getText()); //item.putExtra("uid", user_id); item.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(item); // Close Login Screen onPause(); } }); My activity is here(not much to do it just launches the layout) public class Item extends Activity{ protected SQLiteDatabase myDB=null; protected String name; protected int uid; TextView yeart,year,itemname,comment,commentt,value,valuet,curr,currt; protected void onStart(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.herp); /*name=getIntent().getStringExtra("name"); uid=Integer.parseInt(getIntent().getStringExtra("uid")); itemname=(TextView) findViewById(R.id.itemName);//itemname.setText(name); year=(TextView) findViewById(R.id.itemYear); yeart=(TextView) findViewById(R.id.year); comment=(TextView) findViewById(R.id.itemComments); commentt=(TextView) findViewById(R.id.comments); curr=(TextView) findViewById(R.id.itemcurrent); currt=(TextView) findViewById(R.id.current); value=(TextView) findViewById(R.id.itemValue); valuet=(TextView) findViewById(R.id.value);*/ Database openHelper = new Database(this); myDB = openHelper.getReadableDatabase(); myDB=SQLiteDatabase.openDatabase("data/data/com.example.login2/databases/aeglea", null, SQLiteDatabase.OPEN_READONLY); }} And finally my XML layout <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <TextView android:id="@+id/itemName" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="asdasd" android:gravity="center" android:layout_marginBottom="10px" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="#fff" /> <TextView android:id="@+id/current" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Current" android:textSize="20dp" android:textStyle="bold" /> <TextView android:id="@+id/itemcurrent" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="asdasd" /> <TextView android:id="@+id/year" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Year" android:textSize="20dp" android:textStyle="bold" /> <TextView android:id="@+id/itemYear" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="asdasd" /> <TextView android:id="@+id/value" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Value" android:textSize="20dp" android:textStyle="bold" /> <TextView android:id="@+id/itemValue" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="TextView" /> <TextView android:id="@+id/comments" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="Comments" android:textSize="20dp" android:textStyle="bold" /> <TextView android:id="@+id/itemComments" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="TextView" /> </LinearLayout>

  • Passwords and Keys in Linux

    - by PeanutsMonkey
    In a fit of desperation when I had my wireless connection die on me, I thought it was a problem with the key I had created at the start when I initially configured the wireless connection and hence deleted it. The option to create the key had presented itself when I created the wireless connection. It no longer asks me to. Now I am back online, do I have re-create the password and key I had before? If so, what do I choose and why? The options I have are as follows; PGP Stored password Password keyring Secure shell key The first and last option seem to be obvious and I have no idea about the differences between the second and third options. Why do I need a stored password or password keyring in all scenarios and not just the wireless issue I ran into? EDIT 0 Further to Belisama's comment, I have amended my question. EDIT 1 As requested, I have attached a screenshot

  • Kickstarting VMWare ESX 4.1 (Error: No NIC with name bootif)

  • AT91SAM7X512's SPI peripheral gets disabled on write to SPI_TDR

    - by Dor
    My AT91SAM7X512's SPI peripheral gets disabled on the X time (X varies) that I write to SPI_TDR. As a result, the processor hangs on the while loop that checks the TDRE flag in SPI_SR. This while loop is located in the function SPI_Write() that belongs to the software package/library provided by ATMEL. The problem occurs arbitrarily - sometimes everything works OK and sometimes it fails on repeated attempts (attemp = downloading the same binary to the MCU and running the program). Configurations are (defined in the order of writing): SPI_MR: MSTR = 1 PS = 0 PCSDEC = 0 PCS = 0111 DLYBCS = 0 SPI_CSR[3]: CPOL = 0 NCPHA = 1 CSAAT = 0 BITS = 0000 SCBR = 20 DLYBS = 0 DLYBCT = 0 SPI_CR: SPIEN = 1 After setting the configurations, the code verifies that the SPI is enabled, by checking the SPIENS flag. I perform a transmission of bytes as follows: const short int dataSize = 5; // Filling array with random data unsigned char data[dataSize] = {0xA5, 0x34, 0x12, 0x00, 0xFF}; short int i = 0; volatile unsigned short dummyRead; SetCS3(); // NPCS3 == PIOA15 while(i-- < dataSize) { mySPI_Write(data[i]); while((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); dummyRead = SPI_Read(); // SPI_Read() from Atmel's library } ClearCS3(); /**********************************/ void mySPI_Write(unsigned char data) { while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TXEMPTY) == 0); AT91C_BASE_SPI0->SPI_TDR = data; while ((AT91C_BASE_SPI0->SPI_SR & AT91C_SPI_TDRE) == 0); // <-- This is where // the processor hangs, because that the SPI peripheral is disabled // (SPIENS equals 0), which makes TDRE equal to 0 forever. } Questions: What's causing the SPI peripheral to become disabled on the write to SPI_TDR? Should I un-comment the line in SPI_Write() that reads the SPI_RDR register? Means, the 4th line in the following code: (The 4th line is originally marked as a comment) void SPI_Write(AT91S_SPI *spi, unsigned int npcs, unsigned short data) { // Discard contents of RDR register //volatile unsigned int discard = spi->SPI_RDR; /* Send data */ while ((spi->SPI_SR & AT91C_SPI_TXEMPTY) == 0); spi->SPI_TDR = data | SPI_PCS(npcs); while ((spi->SPI_SR & AT91C_SPI_TDRE) == 0); } Is there something wrong with the code above that transmits 5 bytes of data? Please note: The NPCS line num. 3 is a GPIO line (means, in PIO mode), and is not controlled by the SPI controller. I'm controlling this line by myself in the code, by de/asserting the ChipSelect#3 (NPCS3) pin when needed. The reason that I'm doing so is because that problems occurred while trying to let the SPI controller to control this pin. I didn't reset the SPI peripheral twice, because that the errata tells to reset it twice only if I perform a reset - which I don't do. Quoting the errata: If a software reset (SWRST in the SPI Control Register) is performed, the SPI may not work properly (the clock is enabled before the chip select.) Problem Fix/Workaround The SPI Control Register field, SWRST (Software Reset) needs to be written twice to be cor- rectly set. I noticed that sometimes, if I put a delay before the write to the SPI_TDR register (in SPI_Write()), then the code works perfectly and the communications succeeds. Useful links: AT91SAM7X Series Preliminary.pdf ATMEL software package/library spi.c from Atmel's library spi.h from Atmel's library An example of initializing the SPI and performing a transfer of 5 bytes is highly appreciated and helpful.

  • Nginx user subdomains, should I proxy_pass?

    - by Kevin L.
    I am trying to setup user subdomains, serving content from specific folders: www.example.com/username served from username.example.com (just like github pages). I've looked at Nginx rewrites, but I don't want the browser to redirect--I want the domain to be username.example.com. Anyway, a comment on this question says that I cannot rewrite host, only proxy to it. I tried to setup a proxy_pass, but all of the documentation and examples show it being used to (obviously) proxy to a service on another host or port, but in my case I want to just proxy to another location on the same host and port. Is this the appropriate way to tackle this problem, and if so, what is the right Nginx config syntax?

  • How to see when stored procedures have last run

    - by Brandon Moore
    I want to see a listing of all the stored procs for each database on a server along with when the last time that store proc was run. I'm pretty good with SQL but I don't know about looking at stats like this that sql keeps so I'd appreciate a little help finding this info. EDIT: From the answers I'm getting it sounds like this is not possible the way I thought it would be. I was thinking that it could be done similarly to how you can see when a table was last accessed: select t.name, user_seeks, user_scans, user_lookups, user_updates, last_user_seek, last_user_scan, last_user_lookup, last_user_update from sys.dm_db_index_usage_stats i JOIN sys.tables t ON (t.object_id = i.object_id) where database_id = db_id() The above script was stolen from a comment on http://blog.sqlauthority.com/2009/05/09/sql-server-find-last-date-time-updated-for-any-table/.
