  • SQL Code Smells

    - by Lijo
    Hi Team, Could you please list some of the bad practices in SQL, that novice people do? I have found the use of "WHILE loop" in scenarios which could be resolved using set operations. Another example is inserting data only if it does not exist. This can be achieved using LEFT OUTER JOIN. Some people go for "IF" Any other thoughts? Thanks Lijo

  • Problem in finalizing the link list in C#

    - by Yasin
    My code was almost finished that a maddening bug came up! when i nullify the last node to finalize the link list , it actually dumps all the links and make the first node link Null ! when i trace it , its working totally fine creating the list in the loop but after the loop is done that happens and it destroys the rest of the link by doing so, and i don't understand why something so obvious is becoming problematic! (last line) struct poly { public int coef; public int pow; public poly* link;} ; poly* start ; poly* start2; poly* p; poly* second; poly* result; poly* ptr; poly* start3; poly* q; poly* q2; private void button1_Click(object sender, EventArgs e) { string holder = ""; IntPtr newP = Marshal.AllocHGlobal(sizeof(poly)); q = (poly*)newP.ToPointer(); start = q; int i = 0; while (this.textBox1.Text[i] != ',') { holder += this.textBox1.Text[i]; i++; } q->coef = int.Parse(holder); i++; holder = ""; while (this.textBox1.Text[i] != ';') { holder += this.textBox1.Text[i]; i++; } q->pow = int.Parse(holder); holder = ""; p = start; //creation of the first node finished! i++; for (; i < this.textBox1.Text.Length; i++) { newP = Marshal.AllocHGlobal(sizeof(poly)); poly* test = (poly*)newP.ToPointer(); while (this.textBox1.Text[i] != ',') { holder += this.textBox1.Text[i]; i++; } test->coef = int.Parse(holder); holder = ""; i++; while (this.textBox1.Text[i] != ';' && i < this.textBox1.Text.Length - 1) { holder += this.textBox1.Text[i]; if (i < this.textBox1.Text.Length - 1) i++; } test->pow = int.Parse(holder); holder = ""; p->link = test; //the addresses are correct and the list is complete } p->link = null; //only the first node exists now with a null link! }

    - by Gal V
    Hello all, I'm trying to read all filenames from a specified (server- not client) folder, and insert all the filenames into a javascript Array. It should behave like the Directory.GetFiles method in ASP.NET C#. I created a new array, and I just need the loop method (Javascript or jQuery) to iterate in the specific folder, and insert all the filenames into the array. Thanks all helpers!

  • Why is System.arraycopy native in Java?

    - by James B
    I was surprised to see in the Java source that System.arraycopy is a native method. Of course the reason is because it's faster. But what native tricks is the code able to employ that make it faster? Why not just loop over the original array and copy each pointer to the new array - surely this isn't that slow and cumbersome? Thanks, -James

  • How to convert records including 'include' associations to JSON.

    - by 99miles
    If I do something like: result = Appointment.find( :all, :include => :staff ) logger.debug { result.inspect } then it only prints out the Appointment data, and not the associated staff data. If I do result[0].staff.inpsect then I get the staff data of course. The problem is I want to return this to AJAX as JSON, including the staff rows. How do I force it to include the staff rows, or do I have to loop through and create something manually?

  • Ordering Wordpress posts by most recent comment

    - by James
    I'm wanting to order Wordpress posts by the most recent comment. To the best of my knowledge this isn't possible using the WP_Query object, and would require a custom $wpdb query, which I can easily write. However, I then don't know how to setup the loop to run off this object. Can anyone help?

  • Editing Neo Slider to move in one direction

    - by user2106416
    I have a website with brandspace theme from pixelentity. Currently, the slider move from right to left ( auto transition) . But, when the slider reaches the last image, it will go back to the first image by making all previous images sliding back from left to right. I want to make the slider to have a normal transition,i.e. going back to first image but still with the image sliding from right to left. Below is the slider.php code.: <?php $t =& peTheme(); ?> <?php list($pid,$conf,$loop) = $t->template->data(); ?> <?php $w = $t->media->width(940); ?> <?php $h = $t->media->height(300); ?> <div class="peSlider peVolo" data-autopause="disabled" data-plugin="<?php echo apply_filters("pe_theme_slider_plugin","peVolo"); ?>" data-controls-arrows="edges-full" data-controls-bullets="disabled" data-icon-font="enabled"> <?php while ($slide =& $loop->next()): ?> <?php $link = empty($slide->link) ? false: $slide->link; ?> <?php $img = $t->image->resizedImg($slide->img,$w,$h); ?> <div data-delay="4" <?php echo $slide->idx == 0 ?

  • Issues with LINQ (to Entity) [adding records]

    - by Mario
    I am using LINQ to Entity in a project, where I pull a bunch of data (from the database) and organize it into a bunch of objects and save those to the database. I have not had problems writing to the db before using LINQ to Entity, but I have run into a snag with this particular one. Here's the error I get (this is the "InnerException", the exception itself is useless!): New transaction is not allowed because there are other threads running in the session. I have seen that before, when I was trying to save my changes inside a loop. In this case, the loop finishes, and it tries to make that call, only to give me the exception. Here's the current code: try { //finalResult is a list of the keys to match on for the records being pulled foreach (int i in finalResult) { var queryEff = (from eff in dbMRI.MemberEligibility where eff.Member_Key == i && eff.EffDate >= DateTime.Now select eff.EffDate).Min(); if (queryEff != null) { //Add a record to the Process table Process prRecord = new Process(); prRecord.GroupData = qa; prRecord.Member_Key = i; prRecord.ProcessDate = DateTime.Now; prRecord.RecordType = "F"; prRecord.UsernameMarkedBy = "Autocard"; prRecord.GroupsId = qa.GroupsID; prRecord.Quantity = 2; prRecord.EffectiveDate = queryEff; dbMRI.AddObject("Process", prRecord); } } dbMRI.SaveChanges(); //<-- Crashes here foreach (int i in finalResult) { var queryProc = from pro in dbMRI.Process where pro.Member_Key == i && pro.UsernameMarkedBy == "Autocard" select pro; foreach (var qp in queryProc) { Audit aud = new Audit(); aud.Member_Key = i; aud.ProcessId = qp.ProcessId; aud.MarkDate = DateTime.Now; aud.MarkedByUsername = "Autocard"; aud.GroupData = qa; dbMRI.AddObject("Audit", aud); } } dbMRI.SaveChanges(); //<-- AND here (if the first one is commented out) } catch (Exception e) { //Do Something here } Basically, I need it to insert a record, get the identity for that inserted record and insert a record into another table with the identity from the first record. Given some other constraints, it is not possible to create a FK relationship between the two (I've tried, but some other parts of the app won't allow it, AND my DBA team for whatever reason hates FK's, but that's for a different topic :)) Any ideas what might be causing this? Thank!

  • IPC between multiple processes on multiple servers

    - by z8000
    Let's say you have 2 servers each with 8 CPU cores each. The servers each run 8 network services that each host an arbitrary number of long-lived TCP/IP client connections. Clients send messages to the services. The services do something based on the messages, and potentially notify N1 of the clients of state changes. Sure, it sounds like a botnet but it isn't. Consider how IRC works with c2s and s2s connections and s2s message relaying. The servers are in the same data center. The servers can communicate over a private VLAN @1GigE. Messages are < 1KB in size. How would you coordinate which services on which host should receive and relay messages to connected clients for state change messages? There's an infinite number of ways to solve this problem efficiently. AMQP (RabbitMQ, ZeroMQ, etc.) Spread Toolkit N^2 connections between allservices (bad) Heck, even run IRC! ... I'm looking for a solution that: perhaps exploits the fact that there's only a small closed cluster is easy to admin scales well is "dumb" (no weird edge cases) What are your experiences? What do you recommend? Thanks!

  • Simaltaneous connections with PHP and SOAP?

    - by Dov
    I'm new to using SOAP and understanding the utmost basics of it. I create a client resource/connection, I then run some queries in a loop and I'm done. The issue I am having is when I increase the iterations of the loop, ie: from 100 to 1000, it seems to run out of memory and drops an internal server error. How could I possibly run either a) multiple simaltaneous connections or b) create a connection, 100 iterations, close connection, create connection.. etc. "a)" looks to be the better option but I have no clue as to how to get it up and running whilst keeping memory (I assume opening and closing connections) at a minimum. Thanks in advance! index.php <?php // set loops to 0 $loops = 0; // connection credentials and settings $location = 'https://theconsole.com/'; $wsdl = $location.'?wsdl'; $username = 'user'; $password = 'pass'; // include the console and client classes include "class_console.php"; include "class_client.php"; // create a client resource / connection $client = new Client($location, $wsdl, $username, $password); while ($loops <= 100) { $dostuff; } ?> class_console.php <?php class Console { // the connection resource private $connection = NULL; /** * When this object is instantiated a connection will be made to the console */ public function __construct($location, $wsdl, $username, $password, $proxyHost = NULL, $proxyPort = NULL) { if(is_null($proxyHost) || is_null($proxyPort)) $connection = new SoapClient($wsdl, array('login' => $username, 'password' => $password)); else $connection = new SoapClient($wsdl, array('login' => $username, 'password' => $password, 'proxy_host' => $proxyHost, 'proxy_port' => $proxyPort)); $connection->__setLocation($location); $this->connection = $connection; return $this->connection; } /** * Will print any type of data to screen, where supported by print_r * * @param $var - The data to print to screen * @return $this->connection - The connection resource **/ public function screen($var) { print '<pre>'; print_r($var); print '</pre>'; return $this->connection; } /** * Returns a server / connection resource * * @return $this->connection - The connection resource */ public function srv() { return $this->connection; } } ?>

  • Very high-pitched noise when computer does something intense?

    - by Starkers
    "Intense" is the best word I can use to describe it because I'm not sure what it is, whether it's RAM, GPU or CPU. If I pan the camera in unity: A high pitched noise issues from the computer. The picosecond I start panning the sound starts. Stops the picosecond I stop panning. If I start an infinite loop: 2.0.0p247 :016 > x = 1 => 1 2.0.0p247 :017 > while x < 2 do 2.0.0p247 :018 > puts 'huzzah!' 2.0.0p247 :019?> end huzzah! huzzah! huzzah! An identical high pitched noise can be heard. I don't think it's the GPU due to this simple experiment. Or any monitor-weirdness (although the sound does sound like one of those old CRT monitors if you're old enough to be young when those things were about) The CPU? Or maybe my SSD? It's my first SSD and the first time I've heard this noise. Should I be worried? Regardless, what's causing this sound? I can't think what would cause such high frequency vibrations. I built the PC myself. Not enough heat paste on the CPU? Too much? Just no idea what's going on. Info: CPU Type QuadCore Intel Core i5-3570K, 3800 MHz (38 x 100) Motherboard Name Asus Maximus V Extreme Flash Memory Type Samsung 21nm TLC NAND Video Adapter Asus HD7770
