  • Migrating from Physical SQL (SQL2000) To VMWare machine (SQL2008) - Transferring Large DB

    - by alex
    We're in the middle of migrating from a windows & SQL 2000 box to a Virtualised Win & SQL 2k8 box The VMWare box is on a different site, with better hardware, connectivity etc... The old(current) physical machine is still in constant use - I've taken a backup of the DB on this machine, which is 21GB Transfering this to our virtual machine took around 7+ hours - which isn't ideal when we do the "actual" switchover. My question is - How should I handle the migration better? Could i set up our current machine to do log shipping to the VM machine to keep up to date? then, schedule down time out of hours to do the switch over? Is there a better way?

  • Distributing a function over a single dimension of an array in MATLAB?

    - by Alex Feinman
    I often find myself wanting to collapse an n-dimensional matrix across one dimension, and can't figure out if there is a concise incantation I can use to do this. For example, when parsing an image, I often want to do something like this. (Note! Illustrative example only. I know about rgb2gray for this specific case.) img = imread('whatever.jpg'); s = size(img); for i=1:s(1) for j=1:s(2) bw_img = mean(img(i,j,:)); end end I would love to express this as something like: bw = on(color, 3, @mean); or bw(:,:,1) = mean(color); Is there a short way to do this?

  • Changing ylim (axis limits) drops data falling outside range. How can this be prevented?

    - by Alex Holcombe
    df <- data.frame(age=c(10,10,20,20,25,25,25),veg=c(0,1,0,1,1,0,1)) g=ggplot(data=df,aes(x=age,y=veg)) g=g+stat_summary(fun.y=mean,geom="point") Points reflect mean of veg at each age, which is what I expected and want to preserve after changing axis limits with the command below. g=g+ylim(0.2,1) Changing axis limits with the above command unfortunately causes veg==0 subset to be dropped from the data, yielding "Warning message: Removed 4 rows containing missing values (stat_summary)" This is bad because now the data plot (stat_summary mean) omits the veg==0 points. How can this be prevented? I simply want to avoid showing the empty part of the plot- the ordinate from 0 to .2, but not drop the associated data from the stat_summary calculation.

  • How to learn Ruby on Rails as a complete Programming Beginner?

    - by Alex
    I want to build a scalable dynamic Web Application. I have never programmed an Object Oriented language before. Or, let's just say I am completely new to programming, because the previous experiences aren't worth talking about. I know I have a really big task ahead of me ^^ but I wanted to get into coding for the last 10 years and now that I'm finally doing it, I would like to know how to get there in the most efficient way. Any good books/tutorials you could recommend? Would it really make sense to learn other, better documented languages before learning RoR? Or would it be better for a beginner to learn C# with ASP.NET first? Thank you for your help in advance ;-)

  • Linq ChangeConflictException occurs when submitting DataContext changes

    - by Alex
    System.Data.Linq.ChangeConflictException: 2 of X updates failed. at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at PROJECT.Controllers.HomeController.ClickProc(Int32 id, String code, String n) This is what I get very often. This action is done thousands of times a day, and I get this exception about once every 5 seconds. From what I understand it happens when something changes in the database in the period between creating DataContext and updating it. Am I right? How can I fix it? Update I just debugged the error and found the following: Table name: dbo.Stats current value: 9852039 original value: 9852038 database value: 9852039 The Stats table is updated constantly. So how can I still make LINQ save the changes. With "classical" SQL Server access through SqlDataCommand I never had problems like that.

  • How can I increment a Smarty variable?

    - by alex
    I am not usually a Smarty guy, so I'm a bit stuck. I want to echo the index of an array, but I want to increment it each time I echo it. This is what I have... <ul> {foreach from=$gallery key=index item=image} <li> <img src="{$image}" alt="" id="panel-{$index++}" /> </li> {/foreach} </ul> It doesn't work. Is the best way to do this to pre-process the array before handing it to Smarty? Is there a way I can do this using Smarty?

  • RSA key length and export limitations

    - by Alex Stamper
    I know, there are a lot of limitations to the length of used key (import and export limitations for nearly each country). Usually, it varies from 64 to 256 bits. To use more bits, it is obligatory to ask permission from authorities. But it is recommended to use 1024 bits keys for RSA as minimum! Does it mean that I cannot just use RSA without any problems with law and so on?

  • Does this incorporate JavaScript closures?

    - by alex
    In trying to learn JavaScript closures, I've confused myself a bit. From what I've gathered over the web, a closure is... Declaring a function within another function, and that inner function has access to its parent function's variables, even after that parent function has returned. Here is a small sample of script from a recent project. It allows text in a div to be scrolled up and down by buttons. var pageScroll = (function() { var $page, $next, $prev, canScroll = true, textHeight, scrollHeight; var init = function() { $page = $('#secondary-page'); // reset text $page.scrollTop(0); textHeight = $page.outerHeight(); scrollHeight = $page.attr('scrollHeight'); if (textHeight === scrollHeight) { // not enough text to scroll return false; }; $page.after('<div id="page-controls"><button id="page-prev">prev</button><button id="page-next">next</button></div>'); $next = $('#page-next'); $prev = $('#page-prev'); $prev.hide(); $next.click(scrollDown); $prev.click(scrollUp); }; var scrollDown = function() { if ( ! canScroll) return; canScroll = false; var scrollTop = $page.scrollTop(); $prev.fadeIn(500); if (scrollTop == textHeight) { // can we scroll any lower? $next.fadeOut(500); } $page.animate({ scrollTop: '+=' + textHeight + 'px'}, 500, function() { canScroll = true; }); }; var scrollUp = function() { $next.fadeIn(500); $prev.fadeOut(500); $page.animate({ scrollTop: 0}, 500); }; $(document).ready(init); }()); Does this example use closures? I know it has functions within functions, but is there a case where the outer variables being preserved is being used? Am I using them without knowing it? Thanks Update Would this make a closure if I placed this beneath the $(document).ready(init); statement? return { scrollDown: scrollDown }; Could it then be, if I wanted to make the text scroll down from anywhere else in JavaScript, I could do pageScroll.scrollDown(); I'm going to have a play around on http://www.jsbin.com and report back

    I am working on a browser plug-in for Firefox, and I would like to be able to do some automated testing to make sure that it's handling a variety of different HTML/JavaScript features correctly. Does anyone know of a good downloadable corpus of HTML and/or JavaScript pages that could be used for this type of testing?

  • In a Windows forms application, how can I setup can I set up the SelectedIndexChanged handle for 4 d

    - by Alex
    In a Windows forms application, within a DataGridView, I have 4 different DataGridCombobox controlshow can I set up the handler SelectedIndexChanged handler for the first combobox via the EditingControlShowing event. I added code for a second combobox but the SelectedIndexChanged didn't get wired up. Here's my code. Any advice would be appreciated. private ComboBox countryCombo; private EventHandler countryHandler; private ComboBox partCombo; private EventHandler partHandler; private void dataGridView2_EditingControlShowing(object sender, DataGridViewEditingControlShowingEventArgs e) { countryCombo = e.Control as ComboBox; if (countryCombo != null) { //remove any existing handler if there is one countryCombo.SelectedIndexChanged -= countryHandler; //add the new handler countryCombo.SelectedIndexChanged += new EventHandler(countryCombo_SelectedIndexChanged); } if (partCombo != null) { partCombo.SelectedIndexChanged -= partHandler; partCombo.SelectedIndexChanged += new EventHandler(partCombo_SelectedIndexChanged); } } private void countryCombo_SelectedIndexChanged(object sender, EventArgs e) { ComboBox box = (ComboBox) sender; //MessageBox.Show(box.Items.Count.ToString()); int rowNum = dataGridView2.CurrentCell.RowIndex; dataGridView2.BeginEdit(false); dataGridView2.Rows[0].Cells[2].Value = "abcdef"; dataGridView2.EndEdit(); } private void dataGridView2_CellContentClick(object sender, DataGridViewCellEventArgs e) { int cellColumn = e.ColumnIndex; //MessageBox.Show("Column is: " + cellColumn.ToString()); } private void partCombo_SelectedIndexChanged(object sender, EventArgs e) { ComboBox box = (ComboBox)sender; string partNumber = box.SelectedValue as string; // ToDo: now we need to get the HTSUS from the database so we can //populate the field int rowNum = dataGridView2.CurrentCell.RowIndex; dataGridView2.BeginEdit(false); dataGridView2.Rows[0].Cells[2].Value = "abcdef"; dataGridView2.EndEdit(); } } Al D.

  • packing fields of a class into a byte array in c#

    - by alex
    Hi all: I am trying to create a fast way to convert c# classes into byte array. I thought of serializing the class directly to a byte array using an example I found: // Convert an object to a byte array private byte[] ObjectToByteArray(Object obj) { if(obj == null) return null; BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); bf.Serialize(ms, obj); return ms.ToArray(); } But the byte array I got contains some other information that are not related to the fields in the class. I guess it is also converting the Properties of the class. Is there a way to serialize only the fields of the class to a byte array? Thanks

  • How do I make PyScripter work? Says it cant find python26.dll

    - by Alex
    I installed PyScript to try it out but it just wont start. It only gives me the error: "Error126: Could not open Dll "python26.dll" followed by: "Python could not be properly initialized. We must quit." I think this may have something to do with the PYTHONPATH but since I'm a newbie and dont know what it is or exactly what to put in the PYTHONPATH, after some googling, I ask here. Also, when I tried to install wxPython it was impossible becouse the PYTHONPATH could not be found.(Just a side note) I have installed ActivePython 2.6 and the PATH is set so I can access python in cmd.

  • Images are overflowing their container in IE8 with Fancybox

    - by alex
    In a sort of follow up to this question, I have another problem in IE8. When clicking the gallery and the lightbox appears, the images are overflowing their containing element (by the looks of things). Has anyone ever experienced this before? Of course, the good guys (Firefox/Safari/etc) display it perfectly. How do I fix this? Thanks UPDATE Should I just got with a new Lightbox?
