  • How can I solve this SAT direct corner intersection edge case?

    - by ssb
    I have a working SAT implementation, but I am running into a problem where direct collisions at a corner do not work for tiled surfaces. That is, it clips on the surface when going in a certain direction because it gets hung up on one of the tiles, and so, for example, if I walk across a floor while holding both down and left, the player will stop when meeting the next shape because the player will be colliding with the right side rather than with the top of the floor tile. This illustration shows what I mean: The top block will translate right first and then up. I have checked here and here which are helpful, but this does not address what I should do in a situation where I don't have a tile-based world. My usage of the term "tile" before isn't really accurate since what I'm doing here is manually placing square obstacles next to each other, not assigning them spots on a grid. What can I do to fix this?

  • SIMPLEST way to set up password protection for a static site, with basic admin UI?

    - by Joseph Turian
    I have a static site. I would like the simplest approach to password protecting a directory, with a basic admin UI for adding/removing users. I will have so few users that I don't care about performance. I don't care if it's PHP or Django or whatever, I just want a complete software package. Apache basic auth isn't good, because you can't log out. Nor is there a UI for adding users. I tried throwing everything behind Django auth and serving the files through Django. However, Chrome treats all my text/css headers as text/plain, so I don't get any stylesheets showing. I can't use mod_xsendfile on my server because I can't reconfigure Apache to add new modules. I think this approach is overkill anyway. I can try configuring Nginx's X-Accel-Redirect, however that requires implementing all the Django code for auth myself, and I'd prefer an existing solution. However, this is my backup plan. Is there a code package that implements authentication with basic admin for a static site?

  • Should I use a separate 'admin' user as my "root sudo" or grant sudo to my 'app' user?

    - by AJB
    I'm still wrapping my brain around the Ubuntu 'nullify root' user management philosophy (and Linux in general) and I'm wondering if I should 'replace' my root user with a user called 'admin' (which basically has all the powers of the root, when using sudo) and create another user called 'app' that will be the primary user for my app. Here's the context: I'll be running a LNMP stack on Ubuntu 12.04 Server LTS. There will be only one app running on the server. The 'app' user needs to have SUPER privileges for MySQL. PHP will need to be able to exec() shell commands. The 'app' user will need to be able to transfer files via SFTP. And I'm thinking this would be the best approach: nullify 'root' user create a user called 'admin' that will be a full sudoer of root, this will be the new "root" user of NGINX, PHP, and MySQL (and all system software) grant SUPER privileges to 'app' in MySQL Grant SFTP privileges to only the 'app' user. As I'm new to this, and the information I've found in researching it tends to be of a more general nature, I'm wondering if this is a solid approach, or if it's unorthodox in a way that would cause issues down the road. Thanks in advance for any help.

  • How to direct a Network Solutions domain name to an html website hosted on Google Drive? [on hold]

    - by Air Conditioner
    To begin with, I'd wanted to take advantage of HTML, CSS, and so on to build a website that looks and works just as I'd like it to. I took a look around on how I could make that work, and I soon saw a lifehacker article showing that its possible to host website files on google drive. I then made sure that the folder containing the files was shared publicly throughout the web, and I now have a working 'google drive hosted' domain for the website. However, I did want to have the custom domain, and so I registered one with network solutions. So now, I'm curious on how I should direct my Network Solutions domain to the index.html I'm hosting on google drive. Would anyone have an Idea?

  • Enormous data and PHP errors

    - by salamis
    I am currently using the following HighCharts:HighStock:Charts: http://www.highcharts.com/stock/demo/data-grouping in order to display the data returned from the server. We retrieve the data from a MySQL database and is really big. We are storing sensor metrics every 1 second. After a while we got the following error: [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4756882 bytes) in C:\\wamp\\www\\admin\\getTrends.php on line 156, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP Stack trace:, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 1. {main}() C:\\wamp\\www\\admin\\getTrends.php:0, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 2. getTrendsDataAI() C:\\wamp\\www\\admin\\getTrends.php:33, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 3. printResults() C:\\wamp\\www\\admin\\getTrends.php:102, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 4. createData() C:\\wamp\\www\\admin\\getTrends.php:230, referer: http://localhost/admin/trends.php [Wed Sep 12 00:15:56 2012] [error] [client 127.0.0.1] PHP 5. implode() C:\\wamp\\www\\admin\\getTrends.php:156, referer: http://localhost/admin/trends.php What is the best solution to return this data as JSON object to HighStocks for viewing? And how can we overcome the PHP limitation? Shall we return chunk of data each time? How do they usually present enormous amount of data to the users and creating charts and reports from this data? Another big problem that we need to overcome is that the returned JSON object is enormous. At this point is around 20-30 mbs and it will be much larger in the future. Is it ok to return this data to the user and perform everything client side? Any suggestions or thoughts welcome.

  • How to set "Run this program as an administrator" programatically.

    - by Patrick
    I'm having a problem with good ol' bdeadmin.exe in Vista. First, let's get the predictable responses out of the way: "You should not require your application to be elevated." This one does. C'est la vie. "You need to embed a manifest file." It is already compiled, it is many years old, the company that created it has no intention of doing it again, and it is installed from a Merge Module (MSM file). "BDE is obsolete, you should be using dbExpress" One and a half million lines of code. 'Nuff said. "Drop a manifest file next to the EXE." Tried that, did nothing. As a test, that same manifest file was able to make several other EXE files require elevation, just not the one I wanted. Something in there is preventing the external manifest from being read. "Create a shortcut and set SLDF_RUNAS_USER." Can't do that, it's a Control Panel applet. The only thing that worked was setting "Run this program as an administrator" under the Compatibility tab of its Properties window. I shouldn't have to tell users to do this. Bad for business. I need to have the installer do this. The MSM file uses a static path. Any ideas?

  • C# DirectSound - Capture buffers not continuous

    - by Wizche
    Hi, I'm trying to capture raw data from my line-in using DirectSound. My problem is that, from a buffer to another the data are just inconsistent, if for example I capture a sine I see a jump from my last buffer and the new one. To detected this I use a graph widget to draw the first 500 elements of the last buffer and the 500 elements from the new one: Snapshot I initialized my buffer this way: format = new WaveFormat { SamplesPerSecond = 44100, BitsPerSample = (short)bitpersample, Channels = (short)channels, FormatTag = WaveFormatTag.Pcm }; format.BlockAlign = (short)(format.Channels * (format.BitsPerSample / 8)); format.AverageBytesPerSecond = format.SamplesPerSecond * format.BlockAlign; _dwNotifySize = Math.Max(4096, format.AverageBytesPerSecond / 8); _dwNotifySize -= _dwNotifySize % format.BlockAlign; _dwCaptureBufferSize = NUM_BUFFERS * _dwNotifySize; // my capture buffer _dwOutputBufferSize = NUM_BUFFERS * _dwNotifySize / channels; // my output buffer I set my notifications one at half the buffer and one at the end: _resetEvent = new AutoResetEvent(false); _notify = new Notify(_dwCapBuffer); bpn1 = new BufferPositionNotify(); bpn1.Offset = ((_dwCapBuffer.Caps.BufferBytes) / 2) - 1; bpn1.EventNotifyHandle = _resetEvent.SafeWaitHandle.DangerousGetHandle(); bpn2 = new BufferPositionNotify(); bpn2.Offset = (_dwCapBuffer.Caps.BufferBytes) - 1; bpn2.EventNotifyHandle = _resetEvent.SafeWaitHandle.DangerousGetHandle(); _notify.SetNotificationPositions(new BufferPositionNotify[] { bpn1, bpn2 }); observer.updateSamplerStatus("Events listener initialization complete!\r\n"); And here is how I process the events. /* Process thread */ private void eventReceived() { int offset = 0; _dwCaptureThread = new Thread((ThreadStart)delegate { _dwCapBuffer.Start(true); while (isReady) { _resetEvent.WaitOne(); // Notification received /* Read the captured buffer */ Array read = _dwCapBuffer.Read(offset, typeof(short), LockFlag.None, _dwOutputBufferSize - 1); observer.updateTextPacket("Buffer: " + count.ToString() + " # " + read.GetValue(read.Length - 1).ToString() + " # " + read.GetValue(0).ToString() + "\r\n"); /* Print last/new part of the buffer to the debug graph */ short[] graphData = new short[1001]; Array.Copy(read, graphData, 1000); db.SetBufferDebug(graphData, 500); observer.updateGraph(db.getBufferDebug()); offset = (offset + _dwOutputBufferSize) % _dwCaptureBufferSize; /* Out buffer not used */ /*_dwDevBuffer.Write(0, read, LockFlag.EntireBuffer); _dwDevBuffer.SetCurrentPosition(0); _dwDevBuffer.Play(0, BufferPlayFlags.Default);*/ } _dwCapBuffer.Stop(); }); _dwCaptureThread.Start(); } Any advise? I'm sure I'm failing somewhere in the event processing, but I cant find where. I had developed the same application using the WaveIn API and it worked well. Thanks a lot...

  • Django shows too many warnings when deleting an object

    Hello! I have two models: class Account(models.Model): main_request = models.ForeignKey('JournalistRequest', related_name='main_request') key = models.CharField(_('Key'), max_length=100) class JournalistRequest(models.Model): account = models.ForeignKey(Account, blank=True, null=True) When I try to delete a JournalistRequest, It shows warning with a lot of nesting, like Are you sure you want to delete the selected ?????? ??? objects?
