  • Does the order of conditions in a WHERE clause affect MySQL performance?

    - by Greg
    Say that I have a long, expensive query, packed with conditions, searching a large number of rows. I also have one particular condition, like a company id, that will limit the number of rows that need to be searched considerably, narrowing it down to dozens from hundreds of thousands. Does make any difference to MySQL performance whether I do this: SELECT * FROM clients WHERE (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar) AND company = :ugh or this: SELECT * FROM clients WHERE company = :ugh AND (firstname LIKE :foo OR lastname LIKE :foo OR phone LIKE :foo) AND (firstname LIKE :bar OR lastname LIKE :bar OR phone LIKE :bar)

  • Can I use the emacs keyboard macro counter as a command prefix?

    - by Sean M
    I'm working on a project in emacs where I'd like to use a keyboard macro that changes slightly with each iteration. When I saw the keyboard macro counter in the manual, that looked like exactly what I needed - but as far as I can tell, that inserts an incrementing number into the current buffer. I want to use an incrementing number as a prefix to another command. For example, instead of inserting 3 into the buffer on the third execution of the macro, I'd like to be able to execute C-u 3 M-x my-command, followed by C-u 4 M-x my-command on the next iteration. Is there way to create a keyboard macro that does this? My specific task is "zipping" two blocks of text in the same buffer together, but even if there's an alternative way to do that specific thing, it'd be good to know the answer to the general question.

  • Deleting Part of An Array in Java to Free Memory on Heap

    - by kate
    I am implementing a dynamic programming algorithm for the knapsack problem in Java. I declare the array and then initialize its size to be [number of objects][capacity of knapsack]. When my number of objects or my capacity gets too large, I get a memory error because I run out of space on the heap. My questions is: If I delete rows from my double array as I go along, will Java free the memory as I delete? Or does Java reserve that memory space for the size of the array I originally created? If it's the latter, is there a way to manually free the memory in Java? Thanks for your Help!

  • Is C# compiler not reporting all errors at once at each compile?

    - by Joan Venge
    When I am compiling this project, it show like 400+ errors in the Error List window, then I go to error sites, fix some, and the number goes to say 120+ errors, and then after fixing some more, the next compile reports like 400+ again. I can see that different files are coming in in the Error List window, so I am thinking the compiler aborts after a certain number of errors? If so, what's the reason for this? Is it not supposed to gather all the errors that are present in the project even if they are over 10K+?

  • Should you apply a language filter to a randomly generated string?

    - by Tim
    A while back I created a licensing system for my companies new product, as well as all products after this one. As with a lot of licensing systems mine generates codes: 25 character product and registration codes, as well as 16 character module unlocking codes. My question is, since some parts of these generated codes are random should I apply a language filter to it to avoid any embarrassing language being given to the end users? I chose to as it was not difficult at all. But has anyone else ever came across something like this? Any viewpoints as to if it is worth the effort?

  • Javascript Phone Swap

    - by Batfan
    I've been trying to find a way to do this but, have not found many resources that specifically relate to this situation. I need a javascript (can make use of Jquery if need be) to swap phone numbers on a site. 2 numbers would be specified. One would show on the site by default. The script needs to be able to create a cookie and do this by recognizing a value in the URL string. For Example: http://www.site.com/index.html?value= '?value=' would be the value. This URL (with the additional variable) would bring the user to the same site but, the variable in the string would set the cookie and display a different number. The default number would not be displayed again until the cookies were removed. Due to the situation with my server, I cannot make use of PHP ( I know, that would make things alot easier :P ) Any help would be greatly appreciated.

  • Plotting a grouped 2 dimensional vector in MATLAB

    - by Hossein
    I am trying to make a plot of a 2-dimensional vector (2D Plot). But I don't want all the datapoints to have the same color on the plot. Each datapoint corresponds to a group. I want to have different colors for each group of datapoints. class=[1 3 2 5 2 5 1 3 3 4 2 2 2] says each datapoint belongs to which group X=[x1,y1;x2,y2;x3,y3;.....] the number of these datapoints are the same as the number of elements in the class vector. Now I want to plot these based on colors.

  • too many threads due to synch communication

    - by MasoudIzzy
    I'm using threads and xmlrpclib in python at the same time. Periodically, I create a bunch of thread to complete a service on a remote server via xmlrpclib. The problem is that, there are times that the remote server doesn't answer. This causes the thread to wait forever for a response which it never gets. Over time, number of threads in this state increases and will reach the maximum number of allowed threads on the system (I'm using fedora). I tried to use socket.setdefaulttimeout(10); but the exception that is created by that will cause the server to defunct. I used it at server side but it seems that it doesn't work :/ Any idea how can I handle this issue?

  • Profiling help required

    - by Mick
    I have a profiling issue - imagine I have the following code... void main() { well_written_function(); badly_written_function(); } void well_written_function() { for (a small number) { highly_optimised_subroutine(); } } void badly_written_function() { for (a wastefully and unnecessarily large number) { highly_optimised_subroutine(); } } void highly_optimised_subroutine() { // lots of code } If I run this under vtune (or other profilers) it is very hard to spot that anything is wrong. All the hotspots will appear in the section marked "// lots of code" which is already optimised. The badly_written_function() will not be highlighted in any way even though it is the cause of all the trouble. Is there some feature of vtune that will help me find the problem? Is there some sort of mode whereby I can find the time taken by badly_written_function() and all of its sub-functions?

  • .htaccess redirect question

    - by russp
    I have a slight problem with .htaccess redirect. I have a dynamic site with 2 levels of variables - content="type -(alpha)" and ID="number" but this is very not seo friendly what I really would like to create is a rewrite rule that generates a "friendly" url for serach engines & users alike. Very much like WordPress does. Each ID is already unique (obviously) and on creation is creating a unique "permalink" field so for example ID=1 has a "permalink field" as "2009/10/27/page title" and ID=100 would be "2010/10/27 page title". I would like folder/wall.php?content=type&ID=number to redirect to folder/permalink.php/html/htm (don't mind a non dynamic extension) Any clues? - this is not right (I know) but it also "breaks" my css file RewriteEngine On RewriteRule wall/content/(.*)/ID/(.*)/ wall.php?content=$1&ID=$2 RewriteRule wall/content/(.*)/ID/(.*) wall.php?content=$1&ID=$2

  • [Android] Text inserted in the edittext is overwritten

    - by Paul
    Hello.. I'm a beginner and am making a calculator (fairly easy), but it's happening the following problem: When Cline in "1" button for example, he enters this number in the EditText, but if you click again the number is overwritten instead of the inserted his side as desired. How do the numbers were placed side by side without overwriting those already there? Note: The layout of buttons and etc. I did in. XML, so I'm not using the keyboard native Android. Thanks!

  • Information stored in a cookie file

    - by jklmuk
    Thanks for you help in advance. I am trying to figure out the structure of the cookie file, more specifically i want to be able to determine the expiry time. From the cookies i have created they all appear to be in a standard format. Name, Value, website,followed by 5 numbers and a star. See example below. name value www.website.co.uk/ 1536 3041141504 30135951 1632526096 30135949 * Obviously the expiry time is one of the numbers, the question is which one. From experiments I have determined that the first and fifth number don't seem to change. In a case where i generated three cookies at the same time with a 1000 second time difference i noticed that the fourth number appeared to increase by 2000 suggesting that this has a connection with the expiry time. Can anyone confirm if i am heading in the right direction? And does any one know how i convert this to a human time and date(preferably in php but any language would give me a starting point) thanks Jason

  • Ideas on limiting content to single printed page?

    - by James Skidmore
    I have 5-6 text areas that users fill out in a template (a couple of columns, basically a newsletter format). I'm needing to limit their content to one printed page, but I'm having a hard time coming up with practical solutions. The printed format (margin, font size, etc.) will be the same for all users, as it's printed from a central source. I've had a couple of ideas, but all of them seem rather unreliable and difficult to implement: Determine height of content using JavaScript and estimate the number of printed pages from that. The problem with this is that browser font sizes can vary, it's only a rough estimate (pixels to inches), etc. Limit the number of characters. This is problematic because there are various text fields, certain characters (like M) take up more space than others (like I), and line breaks obviously count for much more. What ideas do you all have? I appreciate your help!

  • Counting variables per observation per month in Sas.

    - by John
    Hey guys, a quick question, I have data of the following sort: Ticker _ Date _ Fem Analyst (dummy 1 if true) AA _ 04/2001 _ 1 AA _ 04/2001 _ 1 AA _ 04/2001 _ 1 AA _ 05/2002 _ 1 AA _ 05/2002 _ 1 AA _ 07/2002 _ 0 AA _ 04/2003 _ 1 and so on.. What I want to receive is the following: Ticker _ Date _ Number of fem analyst AA _ 04/2001 _ 3 AA _ 05/2002 _ 2 AA _ 07/2002 _ 0 AA _ 04/2003 _ 1 So an easy counting algorithm that allows me to count for the number of analysts per company per month (the date is in 01/04/2002 format but I also have a month count variable which can be used too) Any ideas?

  • Javascript function programming — receiving elaborate parameters

    - by Barney
    I'm writing a Javascript function that would manipulate an array written on-the-fly and sent as a parameter. The function is written as follows: function returnJourney(animation,clean){ var properties = {}; // loads of other inane stuff for(i in animation[0]) properties[animation[0][i]] = animation[0].i; // heaps more inane stuff } The animation in question is a set of parameters for a jQuery animation. Typically it takes the format of ({key:value,key:value},speedAsInteger,modifierAsString). So to kick off initial debugging I call it with: returnJouney(({'foo':'bar'},3000),1); And straight off the bat things are way off. As far as I see it this would have returnJourney acknowledge clean === 1, and animation being an array with an object as its first child and the number 3000 as its second. Firebug tells me animation evaluates as the number 3000. What am I doing wrong?

I am correct in using the GoTalk username 09xxxxxx as the DID, aren't I ? I've tried using my phone number but it makes no difference.

  • problem reading a csv file in python

    - by Hossein
    Hi, I am trying to read a very simple but somehow large(800Mb) csv file using the csv library in python. The delimiter is a single tab and each line consists of some numbers. Each line is a record, and I have 20681 rows in my file. I had some problems during my calculations using this file,it always stops at a certain row. I got suspicious about the number of rows in the file.I used the code below to count the number of row in this file: tfdf_Reader = csv.reader(open('v2-host_tfdf_en.txt'),delimiter=' ') c = 0 for row in tfdf_Reader: c = c + 1 print c To my surprise c is printed with the value of 61722!!! Why is this happening? What am I doing wrong?

  • Construction an logical expression which will count bits in a byte.

    - by danatel
    When interviewing new candidates, we usually ask them to write a piece of C code to count the number of bits with value 1 in a given byte variable (e.g. the byte 3 has two 1-bits). I know all the common answers, such as right shifting eight times, or indexing constant table of 256 precomputed results. But, is there a smarter way without using the precomputed table? What is the shortest combination of byte operations (AND, OR, XOR, +, -, binary negation, left and right shift) which computes the number of bites?

  • Minimized window position in WPF

    - by DrLazer
    I am trying to save the position of a custom dialog to the users registry, so that when they reload the same dialog, it appears in the same place they moved or resized it to previously. I am saving the windows X position Y position Width and Height. It all works fine except for when the dialog is minimized. If the dialog is minimized and the user right clicks the dialogs representation on the taskbar (windows 7) they can click "close this window". Strangely, the number -32030 gets saved in the registry as the X and Y positions but the width and height get saved correctly. Any idea where this number comes from and what to do in this situation thx

  • managedQuery - trying to make 2 data points show when clicked

    Here is what I have now: ListAdapter buildPhonesAdapter(Activity a) { String[] PROJECTION=new String[] { Contacts._ID, Contacts.DISPLAY_NAME, Phone.NUMBER, Email.DATA }; Cursor c=a.managedQuery(Phone.CONTENT_URI, PROJECTION, null, null, null); return(new SimpleCursorAdapter( a, android.R.layout.simple_list_item_2, c, new String[] { Contacts.DISPLAY_NAME, Phone.NUMBER, Email.DATA }, new int[] { android.R.id.text1, android.R.id.text2 })); } ListAdapter buildEmailAdapter(Activity a) { String[] PROJECTION=new String[] { Contacts._ID, Contacts.DISPLAY_NAME, Email.DATA }; Cursor c=a.managedQuery(Email.CONTENT_URI, PROJECTION, null, null, null); return(new SimpleCursorAdapter( a, android.R.layout.simple_list_item_2, c, new String[] { Contacts.DISPLAY_NAME, Email.DATA }, new int[] { android.R.id.text1, android.R.id.text2 })); } Need the 2 variables to show when cursor is picking this new option - I need Email.CONTENT_URI, and Phone.CONTENT_URI, to show when picked - I can get each one to show but need them both to show at same time.

  • data type trouble in php

    - by user225269
    I don't know why but the data type in this code makes a trouble when the id in the url starts with the number zero like this: http://localhost/exp/update.php?id=03A43 In this case the id is 03A43. And my query looks like this: mysql_select_db("school", $con); $result = mysql_query("SELECT * FROM student WHERE IDNO=".(int)$_GET['id']); ?> There is no problem in the design if the id does not start with the number zero. What might be the proper data type for numbers beginning in zero?
