3,014,157 | 0 | <p>Rox suggested WordPress. I would second that. You don't need your own domain to start a Wordpress blog. Just go to wordpress.com and sign up. You will probably get an address like wordpress.com/. The advantage would be that when you get your own domain, you probably can export all your content and import it in your own wordpress installation on that domain.</p> |

34,526,156 | 0 | HTML5 Notification With PHP <p>I noticed Facebook started using the HTML5 notification for desktop and I thought I would start dabbling in it for fun for my blog. My idea is pretty simple: new blog comes out, apache cronjob runs every X minutes and calls a file, does some PHP wizardry and out goes the notification. </p> <p>I have looked online and found examples using <a href="https://codeforgeek.com/2014/10/desktop-notification-like-facebook-using-html5/">node.js and angular</a>, but I'm not comfortable using either of those so I'd rather stick with PHP. </p> <p>Here is my process: The user goes to my blog and will click a button to allow notifications. For brevity, the below code sends the users a notification when they click the "notify" button. This works perfectly, and in theory should subscribe them to any future notifications. </p> <pre><code>if ('Notification' in window) { function notifyUser() { var title = 'example title'; var options = { body: 'example body', icon: 'example icon' }; if (Notification.permission === "granted") { var notification = new Notification(title, options); } else if (Notification.permission !== 'denied') { Notification.requestPermission(function (permission) { if (permission === "granted") { var notification = new Notification(title, options); } }); } } $('#notify').click(function() { notifyUser(); return false; }); } else { //not happening } </code></pre> <p>You can see the <a href="https://jsfiddle.net/qdb1d414/">fiddle</a> of the above. </p> <p>Access to the user is granted and now I should be able to send them notifications whenever I want. Awesome! I then write up a blog entry and it has the ID of XYZ. My cronjob goes and calls the following PHP script, using the above node.js example as a template.</p> <p>(In this example I am just calling the script manually from my phone and watching my desktop screen. Since my desktop is "subscribed" to the same domain, I think the following would/should work.)</p> <pre><code>$num = $_GET['num']; $db = mysql_connect(DB_HOST, DB_USER, DB_PASS); if($db) { mysql_select_db('mydb', $db); $select = "SELECT alert FROM blog WHERE id = ".$num." && alert = 0 LIMIT 1"; $results = mysql_query($select) or die(mysql_error()); $output = ''; while($row = mysql_fetch_object($results)) { $output .= "<script> var title = 'new blog!'; var options = { body: 'come read my new blog!', icon: 'same icon as before or maybe a new one!' }; var notification = new Notification(title, options); </script>"; $update = "UPDATE blog SET alert = 1 WHERE id = ".$num." && alert = 0 LIMIT 1"; mysql_query($update) or die(mysql_error()); } echo $output; } </code></pre> <p>I then check the database and blog entry XYZ's "alert" is now set to "1", yet my desktop browser never got notified. Since my browser is subscribed to the same URL that is pushing out the notification, I would imagine I'd get a message. </p> <p>Either I'm doing something wrong (perhaps PHP isn't the right language for this?), or I'm misunderstanding the spec. Could somebody help point me in the right direction? I think I'm missing something. </p> <p>Thanks a lot. </p> <p><strong>Update 1</strong></p> <p>According to the comments, if I just call a script with this in it:</p> <pre><code> var title = 'new blog!'; var options = { body: 'come read my new blog!', icon: 'same icon as before or maybe a new one!' }; var notification = new Notification(title, options); </code></pre> <p>It should hit all devices that are subscribed to my notifications. I tried this on my phone but my desktop still didn't get a notification. I still think I'm missing something as my notifications seem stuck to one device and can only be called on page-load or on click as opposed to Facebook which sends you notifications even if the page isn't open in your browser. </p> |

You could then put the comparison logic within the <code>Line</code> class in the <code>compareTo</code> method. The logic there will test whether the slope and the intercept match, and if so return <code>0</code>. Other results could return <code>1</code> or <code>-1</code> to enforce ordering, if you want.</p> <p>Obviously, you don't need to implement this interface to effect your desired results. However, as this is homework, doing so will allow you to play around with some features of the JDK, like using sorted Lists, etc. With a sorted list, for example, you could obviate the need for a nested loop, as you would only need to compare the object in question against one you just removed from the <code>Iterator</code> in the previous iteration to see if you need to add it to an existing linelist or start a new one.</p> |

18,043,445 | 0 | <p>So you basically want to <em>detect</em> whether a file is an ISO file or not, and not so much check the file, to see if it's valid (e.g. incomplete, corrupted, ...) ?</p> <p>There's no easy way to do that and there certainly is not a C# function (that I know of) that can do this.</p> <p>The best way to approach this is to guess the amount of bytes per block stored in the ISO. Guess, or simply try all possible situations one by one, unless you have an associated CUE file that actually stores this information. PS. If the ISO is accompanied by a same-name .CUE file then you can be 99.99% sure that it's an ISO file anyway.</p> <p>Sizes would be 2048 (user data) or 2352 (raw or audio) bytes per block. Other sizes are possible as well !!!! I just mentioned the two most common ones. In case of 2352 bytes per block the user data starts at an offset in this block. Usually 16 or 24 depending on the Mode.</p> <p>Next I would try to detect the CD/DVD file-systems. Assume that the image starts at sector 0 (although you could for safety implement a scan that assumes -150 to 16 for instance).</p> <p>You'll need to look into specifics of ISO9660 and UDF for that. Sectors 16, 256 etc. will be interesting sectors to check !!</p> <p>Bottom line, it's not an easy task to do and you will need to familiarize yourself with optical disc layouts and optical disc file-systems (ISO9660, UDF but possibly also HFS and even FAT on BD).</p> <p>If you're digging into this I strongly suggest to get IsoBuster (<a href="http://www.isobuster.com" rel="nofollow">www.isobuster.com</a>) to help you see what the size per block is, what file systems there are, to inspect the different key blocks etc.</p> |

5,328,493 | 0 | IBAction Doesn't Get Called in Subview <p>I am creating a simple app that let's the user view movies after clicking buttons. The first screen you see is the Main Menu with 2 buttons. One of them sends the user to a sub view which I coded as this in an IBAction method:</p> <pre><code>ViewConroller *nextView = [[ViewController alloc] initWithNibName:@"NextMenu" bundle nil]; [self.view addSubview:[nextView view]]; [nextView release]; </code></pre> <p>This part is fine except that the sub view shows a 20 px bar across the bottom of the previous view. I looked around and none of the solutions like <a href="http://stackoverflow.com/questions/3032773/my-view-is-displaying-y-20-dispite-its-frame-set-to-y-0-after-rotation-it-snaps">this one</a> work for me. This isn't even the main problem. On the sub view, whenever I click a button, the app explodes. The IBAction methods break before even executing a line inside the method. Here, in the goBack IBAction method, I am trying to dismiss the subview and go back to the main menu:</p> <pre><code>[self.view removeFromSuperview]; </code></pre> <p>My connections are correct in my XIB files and everything seems to be in order. The buttons just aren't executing. I'm not sure if it has to do with adding the sub view or what. I have done a lot of searching around on google and this website, but I still can't find a solution. </p> <p>Here is an example of the error I'm getting:</p> <pre><code>Terminating app due to uncaught exception 'NSInvalidArgumentException, reason: '-[__NSCFType goBack:]: unrecognized selector sent to instance 0x5640b70' </code></pre> <p>Hopefully you guys can help me out, this is really quite frustrating.

324,323 | 0 | <p>A view is barely more expensive to the computer than writing out the query longhand. A view can save the programmer/user a lot of time writing the same query out time after time, and getting it wrong, and so on. The view may also be the only way to access the data if views are also used to enforce authorization (access control) on the underlying tables.</p> <p>If the query does not perform well, you need to review how the query is formed, and whether the tables all have the appropriate indexes on them. If your system needs accurate statistics for the optimizer to perform well, have you updated those statistics sufficiently recently?</p> <p>Once upon a long time ago, I came across a system where a query generator had created one query that listed seventeen tables in a single FROM clause, including several LEFT OUTER JOIN of a table with itself. And, in fact, closer scrutiny revealed that several of the 'tables' were in fact multi-table views, and some of these also involved self outer joins, and were themselves involved in self outer joins of the view. To say "<em>ghastly</em>" is an understatement. There was a lot of cleanup possible to improve the performance of that query - eliminating unnecessary outer joins, self joins, and so on. (It actually pre-dated the explicit join notation of SQL-92 - I said a long time ago - so the outer join syntax was DBMS-specific.)</p> |

8,893,436 | 0 | <p>Quick question: is the image the same every time or specific to a customer order? I presume it is different or you wouldn't be asking.</p> <p>To clarify: attachments are okay if you sending out invoices/delivery notes/order confirmation. However you are advised to setup your email so that the IP address can be verified directly. You are also advised to use a SPFrecord in your DNS so that the remote mail server can check that your server is allowed to send emails for you. Furthermore, in your order success page you can also ask your customers to add you to their address book, in that way your emails will not be marked as SPAM, regardless of whether you have SPF records and things setup. The only thing is you cannot guarantee customers will do that, so the SPF records and the IP reverse lookup is best. You can also use DomainKeys DKIM for the likes of Yahoo mail - mail delivery isn't what this question is about so you will have to Google DKIM for yourself...</p> <p>Otherwise, attaching an image is simple. See the example at the top of the page of the Zend Programmers Reference Guide on attachments:</p> <p><a href="http://framework.zend.com/manual/en/zend.mail.attachments.html" rel="nofollow">http://framework.zend.com/manual/en/zend.mail.attachments.html</a></p> <p>Keep reading the comments for clarification on how to get the image data included.</p> <p>Hope that helps!</p> |

27,350,762 | 0 | Chain of functions for variadic template arguments <p>I am trying to design a generic, type-safe way to load interleaved data into a OpenGL VBO. My problem is now how to organize the various glVertexAttribPointer() calls. I have defined the buffer data descriptor as follows.</p> <pre><code>template <typename T> struct Descriptor { T vertex; }; template <typename T, typename U> struct Descriptor { T vertex; U normal; }; ... </code></pre> <p>This is basically now all well and simple. However, my problem is that the template functions to actually set the attributes turned out as follows.</p> <pre><code>template <template <class> class Desc, typename T> void setAttributes(const Desc<T>& desc) { // set attributes for vertices ... glVertexAttribPointer(0, sizeof(desc.vertex), ...); } template <template <class, class> class Desc, typename T, typename U> void setAttributes(const Desc<T, U>& desc) { // set attributes for vertices ... glVertexAttribPointer(0, sizeof(desc.vertex), ...); // set attributes for normals ... glVertexAttribPointer(1, sizeof(desc.normal), ...); } ... </code></pre> <p>Basically the problem is that I still ended up with a lot of repetition. Is there a way break these down into two template functions where one only sets vertex attributes and one sets only normals? In pseudocode something like the following.</p> <pre><code>template <class Desc, class T, Args...> void setAttributes(Desc desc) { setVertexAttributes(...); // somehow decide that if there are args left, call again... } template <class Desc, class U, Args...> void setAttributes(Desc desc) { // ...ending up here setNormalAttributes(...); } </code></pre> |
4,805,554 | 0 | Database Snapshot SQL Server 2000 <p>We have a large database that receives records concerning several hundred thousand persons per year. For a multitude of reasons I won't get into when information is entered into the system for a specific person it is often the case that the individual entering the data will be unable to verify whether or not this person is already in the database. Due to legal reqirements, we have to strive towards each individual in our database having a unique identifier (and no individual should have two or more.) Because of data collection issues it'll often be the case that one individual will be assigned many different unique identifiers.</p> <p>We have various automated and manual processes that mostly clean up the database on a set schedule and merge unique identifiers for persons who have had muliple assigned to them.</p> <p>Where we're having problems is we are also legally required to generate reports at year end. We have a set of year-end reports we always generate, however it is also the case that every year several dozen ad hoc reports will be requested by decision makers. Where things get troublesome is because of the continuous merging of unique identifiers, our data is not static. So any reports generated at year end will be based on the data as it existed the last day of the year, 3 weeks later if a decision maker requests a report, whatever we give them can (and will) often conflict direcly with our legally required year end reports. Sometimes we'll merge up to 30,000 identifiers in a month which can greatly change the results of any query.</p> <p>It is understood/accepted that our database is not static, but we are being asked to come up with a method for generating ad hoc reports based off of a static snapshot of the database. So if a report is requested on 1/25 it will be based off the exact same dataset as our year end reports.</p> <p>After doing some research I'm familiar with database snapshots, but we have a SQL Server 2000 database and we have little ability to get that changed in the short-to-medium term and database snapshots are a new feature in the 2005 edition. So my question would be what is the best way to create a queryable snapshot of a database in SQL Server 2000?</p> |
15,087,397 | 0 | <p>Since your scheduled task is actually changing the permissions on the error log file, the only viable options I can see are:</p> <p>1) Make the scheduled task not write to the error_log. Add the following to the top of the cron job:</p> <p><code>error_reporting(E_NONE);</code></p> <p>2) Make the scheduled task write to the system log (event viewer in windows) by issuing the following command at the start of your scheduled task (PHP file):</p> <p><code>ini_set('error_log', 'syslog');</code></p> <p>3) If all of the above do not suit you, you can try scheduling the task as the IIS User/Group. This would insure that the permissions are met and error 500 is no longer caused. </p> <p>There is no magic fix to this, you can either change the scheduled task so it has the same UID/GID as the PHP process, or you can stop logging in the scheduled_task. </p> |
