  • How to get Bash shell history range

    - by Aniti
    How can I get/filter history entries in a specific range? I have a large history file and frequently use history | grep somecommand Now, my memory is pretty bad and I also want to see what else I did around the time I entered the command. For now I do this: get match, say 4992 somecommand, then I do history | grep 49[0-9][0-9] this is usually good enough, but I would much rather do it more precisely, that is see commands from 4972 to 5012, that is 20 commands before and 20 after. I am wondering if there is an easier way? I suspect, a custom script is in order, but perhaps someone else has done something similar before.

  • How to clean completly select2 control?

    - by Candil
    I'm working with the awesome select2 control. I'm trying to clean and disable the select2 with the content too so I do this: $("#select2id").empty(); $("#select2id").select2("disable"); Ok, it works, but if i had a value selected all the items are removed, the control is disabled, but the selected value is still displayed. I want to clear all content so the placeholder would be showed. Here is a example I did where you can see the issue: http://jsfiddle.net/BSEXM/ HTML: <select id="sel" data-placeholder="This is my placeholder"> <option></option> <option value="a">hello</option> <option value="b">all</option> <option value="c">stack</option> <option value="c">overflow</option> </select> <br> <button id="pres">Disable and clear</button> <button id="ena">Enable</button> Code: $(document).ready(function () { $("#sel").select2(); $("#pres").click(function () { $("#sel").empty(); $("#sel").select2("disable"); }); $("#ena").click(function () { $("#sel").select2("enable"); }); }); CSS: #sel { margin: 20px; } Do you have any idea or advice to this?

  • Opening a xul file in response to a toolbar extension button click

    - by Graham
    I'm currently building my first Firefox extension, and am having a little difficulty with one piece of functionality. I'd like to open a new browser tab in response to a button click on the toolbar. The new tab should contain the contents of a webpage, together with some extra buttons. At the moment I've created a separate xul file for the contents of the new tab: <?xml version="1.0"?> <?xml-stylesheet href="chrome://global/skin/" type="text/css"?> <window id="myapp-report-window" title="Example 4.5.1" xmlns:html="http://www.w3.org/1999/xhtml" xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"> <script type="application/x-javascript" src="chrome://myapp/content/main.js" /> <toolbox> <toolbar id="nav-toolbar"> <toolbarbutton label="This-is-going-to-do-some-stuff"/> </toolbar> </toolbox> <iframe id="myapp-report-frame" flex="1"/> <script type="text/javascript"> function loadPage(url){ document.getElementById('myapp-report-frame').setAttribute('src',url); } </script> </window> This xul file is launched via this javascript, referenced from the main myapptoolbar.xul: gBrowser.selectedTab = gBrowser.addTab('chrome://myapp/content/report.xul'); var newTabBrowser = gBrowser.getBrowserForTab(gBrowser.selectedTab); newTabBrowser.addEventListener("load", function(){ loadPage('http://www.somedynamicallysetwebsite.com'); }, true); The problem that I'm having is that the loadPage function is not being found, so the src attribute of the iframe is never set. I'm sure it's some silly scoping problem, but I'm very new to firefox extensions (day 2!) so any help would be much appreciated. Thanks for looking! Graham

  • How do I enable mod_deflate for PHP files?

    - by DM.
    I have a Liquid Web VPS account, I've made sure that mod_deflate is installed and running/active. I used to gzip my css and js files via PHP, as well as my PHP files themselves... However, I'm now trying to do this via mod_deflate, and it seems to work fine for all files except for PHP files. (Txt files work fine, css, js, static HTML files, just nothing that is generated via a PHP file.) How do I fix this? (I used the "Compress all content" option under "Optimize Website" in cPanel, which creates an .htaccess file in the home directory (not public_html, one level higher than that) with exactly the same text as the "compress everything except images" example on http://httpd.apache.org/docs/2.0/mod/mod_deflate.html) .htaccess file: <IfModule mod_deflate.c> SetOutputFilter DEFLATE <IfModule mod_setenvif.c> # Netscape 4.x has some problems... BrowserMatch ^Mozilla/4 gzip-only-text/html # Netscape 4.06-4.08 have some more problems BrowserMatch ^Mozilla/4\.0[678] no-gzip # MSIE masquerades as Netscape, but it is fine # BrowserMatch \bMSIE !no-gzip !gzip-only-text/html # NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48 # the above regex won't work. You can use the following # workaround to get the desired effect: BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html # Don't compress images SetEnvIfNoCase Request_URI .(?:gif|jpe?g|png)$ no-gzip dont-vary </IfModule> <IfModule mod_headers.c> # Make sure proxies don't deliver the wrong content Header append Vary User-Agent env=!dont-vary </IfModule> </IfModule>

  • Host hijacks USB printer from VirtualBox machine

    - by jackhab
    I have Ubuntu 9.1 running Windows XP in VirtualBox. Windows XP is a print server (there is no Linux driver for our printer). The printer is connected via USB and its USB filter is added to virtual machine settings. The problem is that every several hours Ubuntu tries to access the printer (trying to install it) and disconnects it from the virtual machine. The printer remains disconnected until I connect it again manually. I thought it is a problem with Windows power management but disabling sleep/standby in Windows didn't help. Please, advise.

  • How to get nested chain of objects in Linq and MVC2 application?

    - by Anders Svensson
    I am getting all confused about how to solve this problem in Linq. I have a working solution, but the code to do it is way too complicated and circular I think: I have a timesheet application in MVC 2. I want to query the database that has the following tables (simplified): Project Task TimeSegment The relationships are as follows: A project can have many tasks and a task can have many timesegments. I need to be able to query this in different ways. An example is this: A View is a report that will show a list of projects in a table. Each project's tasks will be listed followed by a Sum of the number of hours worked on that task. The timesegment object is what holds the hours. Here's the View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Report.Master" Inherits="System.Web.Mvc.ViewPage<Tidrapportering.ViewModels.MonthlyReportViewModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Månadsrapport </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h1> Månadsrapport</h1> <div style="margin-top: 20px;"> <span style="font-weight: bold">Kund: </span> <%: Model.Customer.CustomerName %> </div> <div style="margin-bottom: 20px"> <span style="font-weight: bold">Period: </span> <%: Model.StartDate %> - <%: Model.EndDate %> </div> <div style="margin-bottom: 20px"> <span style="font-weight: bold">Underlag för: </span> <%: Model.Employee %> </div> <table class="mainTable"> <tr> <th style="width: 25%"> Projekt </th> <th> Specifikation </th> </tr> <% foreach (var project in Model.Projects) { %> <tr> <td style="vertical-align: top; padding-top: 10pt; width: 25%"> <%:project.ProjectName %> </td> <td> <table class="detailsTable"> <tr> <th> Aktivitet </th> <th> Timmar </th> <th> Ex moms </th> </tr> <% foreach (var task in project.CurrentTasks) {%> <tr class="taskrow"> <td class="task" style="width: 40%"> <%: task.TaskName %> </td> <td style="width: 30%"> <%: task.TaskHours.ToString()%> </td> <td style="width: 30%"> <%: String.Format("{0:C}", task.Cost)%> </td> </tr> <% } %> </table> </td> </tr> <% } %> </table> <table class="summaryTable"> <tr> <td style="width: 25%"> </td> <td> <table style="width: 100%"> <tr> <td style="width: 40%"> Totalt: </td> <td style="width: 30%"> <%: Model.TotalHours.ToString() %> </td> <td style="width: 30%"> <%: String.Format("{0:C}", Model.TotalCost)%> </td> </tr> </table> </td> </tr> </table> <div class="price"> <table> <tr> <td>Moms: </td> <td style="padding-left: 15px;"> <%: String.Format("{0:C}", Model.VAT)%> </td> </tr> <tr> <td>Att betala: </td> <td style="padding-left: 15px;"> <%: String.Format("{0:C}", Model.TotalCostAndVAT)%> </td> </tr> </table> </div> </asp:Content> Here's the action method: [HttpPost] public ActionResult MonthlyReports(FormCollection collection) { MonthlyReportViewModel vm = new MonthlyReportViewModel(); vm.StartDate = collection["StartDate"]; vm.EndDate = collection["EndDate"]; int customerId = Int32.Parse(collection["Customers"]); List<TimeSegment> allTimeSegments = GetTimeSegments(customerId, vm.StartDate, vm.EndDate); vm.Projects = GetProjects(allTimeSegments); vm.Employee = "Alla"; vm.Customer = _repository.GetCustomer(customerId); vm.TotalCost = vm.Projects.SelectMany(project => project.CurrentTasks).Sum(task => task.Cost); //Corresponds to above foreach vm.TotalHours = vm.Projects.SelectMany(project => project.CurrentTasks).Sum(task => task.TaskHours); vm.TotalCostAndVAT = vm.TotalCost * 1.25; vm.VAT = vm.TotalCost * 0.25; return View("MonthlyReport", vm); } And the "helper" methods: public List<TimeSegment> GetTimeSegments(int customerId, string startdate, string enddate) { var timeSegments = _repository.TimeSegments .Where(timeSegment => timeSegment.Customer.CustomerId == customerId) .Where(timeSegment => timeSegment.DateObject.Date >= DateTime.Parse(startdate) && timeSegment.DateObject.Date <= DateTime.Parse(enddate)); return timeSegments.ToList(); } public List<Project> GetProjects(List<TimeSegment> timeSegments) { var projectGroups = from timeSegment in timeSegments group timeSegment by timeSegment.Task into g group g by g.Key.Project into pg select new { Project = pg.Key, Tasks = pg.Key.Tasks }; List<Project> projectList = new List<Project>(); foreach (var group in projectGroups) { Project p = group.Project; foreach (var task in p.Tasks) { task.CurrentTimeSegments = timeSegments.Where(ts => ts.TaskId == task.TaskId).ToList(); p.CurrentTasks.Add(task); } projectList.Add(p); } return projectList; } Again, as I mentioned, this works, but of course is really complex and I get confused myself just looking at it even now that I'm coding it. I sense there must be a much easier way to achieve what I want. Basically you can tell from the View what I want to achieve: I want to get a collection of projects. Each project should have it's associated collection of tasks. And each task should have it's associated collection of timesegments for the specified date period. Note that the projects and tasks selected must also only be the projects and tasks that have the timesegments for this period. I don't want all projects and tasks that have no timesegments within this period. It seems the group by Linq query beginning the GetProjects() method sort of achieves this (if extended to have the conditions for date and so on), but I can't return this and pass it to the view, because it is an anonymous object. I also tried creating a specific type in such a query, but couldn't wrap my head around that either... I hope there is something I'm missing and there is some easier way to achieve this, because I need to be able to do several other different queries as well eventually. I also don't really like the way I solved it with the "CurrentTimeSegments" properties and so on. These properties don't really exist on the model objects in the first place, I added them in partial classes to have somewhere to put the filtered results for each part of the nested object chain... Any ideas?

  • Why would certain browsers request all pages on my ASP.Net Web site twice?

    - by Deane
    Firefox is issuing duplicate requests to my ASP.Net web site. It will request a page, get the response, then immediately issue the same request again (well, almost the same -- see below). This happens on every page of this particular Web site (but not any others). IE does not do this, but Chrome also does this. I have confirmed that there is no Location header in the response, and no Javascript or meta tag in the page which would cause the page to be re-requested (if any of these were true, IE would be re-requesting pages as well). I have confirmed this behavior on multiple Firefox installs on multiple machines. Versions vary, but all are 3.x. The only difference between the two requests is the Accepts header. For the first request, it looks like this: Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 For the second request, it looks like this: Accept: */* The Content-Type response header in all cases is: Content-Type: text/html; charset=utf-8 Something else odd -- even though Firefox requests the page twice, it uses the first response and discards the second. I put a counter on a page that increments with every request. I can watch the responses come back (via the Charles proxy). Firefox will get a "1" the first time, and a "2" the second time. Yet it will display the "1," for some reason. Chrome exhibits this exact same behavior. I suspect it's a protocol-level issue, given the difference in Accepts header, but I've never seen this before.

  • Problems migrating databinding in VB.NET from Winforms to ASP.NET 2.0

    - by David
    And this was supposed to be so easy... I have existing business and data access layers that handle the retrieval and update of the data in question. These work great with the existing Winforms application (.Net V2.0) Now, in trying to write a new web-based UI, I'm running into all sorts of problems (last time I wrote asp.net code was in 1.1). Specifically, I can't data bind a text box to a business object. Oh, sure there's the ObjectDataSource but that wants to know how to do CRUD operations on the data. What I'm looking for is something that acts like the 'classic' binding objects so that, in my code, it's as simple as retrieving the object and doing a a refresh. The data component like FormView and DetailsView are so generic-looking that it's ridiculous. The existing application would have tabbed dialogs, text boxes grouped by panels, etc. On top of that, I have a directive to use master pages and unless one control causes it, I can't seem to get the content section to expand. I can't just put a text box 'below' the bottom of "Content1" and have it resize the content section - which gives me the same results as an earlier question I posted when the footer wasn't being 'pushed down' - relative position solved that but doesn't seem to solve it with placing small text boxes in the area. What I want is fairly simple. Something like: bindingobject.datasource = businessdataobject bindingobject.refresh ...and have the text boxes refresh with the new values. Likewise to have 'businessdataobject' properties updated as the user enters new data. I was able to do this with the GridView (grdRequests.DataSource = lstRequests) by making a list of asp:BoundField tags inside the collection of the GridView. Am I tilting at windmills here?

  • Intermittent bug - IE6 showing file as text in browser, rather than as file download

    - by Richard Ev
    In an ASP.NET WebForms 2.0 site we are encountering an intermittent bug in IE6 whereby a file download attempt results in the contents of the being shown directly in the browser as text, rather than the file save dialog being displayed. Our application allows the user to download both PDF and CSV files. The code we're using is: HttpResponse response = HttpContext.Current.Response; response.Clear(); response.AddHeader("Content-Disposition", "attachment;filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.End(); This is called from the code-behind click event handler of a button server control. Where are we going wrong with this approach? Edit Following James' answer to this posting, the code I'm using now looks like this: HttpResponse response = HttpContext.Current.Response; response.ClearHeaders(); // Setting cache to NoCache was recommended, but doing so results in a security // warning in IE6 //response.Cache.SetCacheability(HttpCacheability.NoCache); response.AppendHeader("Content-Disposition", "attachment; filename=\"theFilename.pdf\""); response.ContentType = "application/pdf"; response.BinaryWrite(MethodThatReturnsFileContents()); response.Flush(); response.End(); However, I don't believe that any of the changes made will fix the issue.

  • Set focus to a button in a new TabItem

    - by Jan
    I use a TabControl to display a list of items. The ItemView is a separate control I wrote. <TabControl SelectedItem="{Binding CurrentItem}" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding ItemList}"> <TabControl.ContentTemplate> <DataTemplate> <ctrls:ItemView/> </DataTemplate> </TabControl.ContentTemplate> <TabControl.ItemTemplate> <DataTemplate> <TextBlock Text="{Binding ShortItemDescription}"/> </DataTemplate> </TabControl.ItemTemplate> </TabControl> If the user presses a Button a new ViewModel is added to the list of ViewModels and the TabControl displays it as a new tab. After adding the new tab is selected. <Button Command="{Binding AddItemCommand}" Content="Add item"/> Inside of the new ViewModel is a button that needs to be focused each time a new tab is added. I have tried to use the FocusManager and the Initialized event in the ItemView but these are only called for the first time I add a new tab. <UserControl x:Class="ItemView" ... Initialized="ViewInitialized"> <Grid> ... <!-- Set focus to this button --> <Button Content="Search" Command="{Binding SearchCommand}" Name="SearchButton" Grid.Column="0" Grid.Row="0"/> </Grid> </UserControl> Any ideas?

  • using jquery selector to change attribute in variable returned from ajax request

    - by Blake
    I'm trying to pull in a filename.txt (contains html) using ajax and change the src path in the data variable before I load it into the target div. If I first load it into the div the browser first requests the broken image and I don't want this so I would like to do my processing before I load anything onto the page. I can pull the src values fine but I can't change them. In this example the src values aren't changed. Is there a way to do this with selectors or can they only modify DOM elements? Otherwise I may have to do some regex replace but using a selector will be more convenient if possible. $.ajax( { url: getDate+'/'+name+'.txt', success: function(data) { $('img', data).attr('src', 'new_test_src'); $('#'+target).fadeOut('slow', function(){ $('#'+target).html(data); $('#'+target).fadeIn('slow'); }); } }); My reason is I'm building a fully standalone javascript template system for a newsletter and since images and other things are upload via a drupal web file manager I want the content creators to keep their paths very short and simple and I can then modify them before I load in the content. This will also be distributed on a CD so I can need to change the paths for that so they still work.

  • Using mod-rewrite to conditionally select existing file in a subdirectory based on Host header?

    - by Kevin Hakanson
    I'm working through a problem where I want to select a different static content file based on the incoming Host header. The simple example is a mapping from URLs to files like this: www.example.com/images/logo.gif - \images\logo.gif skin2.example.com/images/logo.gif - \images\skin2\logo.gif skin3.example.com/images/logo.gif - \images\skin3logo.gif I have this working with the following RewriteRules, but I don't like how I have to repeat myself so much. Each host has the same set of rules, and each RewriteCond and RewriteRule has the same path. I'd like to use the RewriteMap, but I don't know how to use it to map the %{HTTP_HOST} to the path. <VirtualHost *:80> DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName www.example.com ServerAlias skin2.example.com ServerAlias skin3.example.com RewriteEngine On RewriteCond %{HTTP_HOST} skin2.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin2/$2 -f RewriteRule ^(.*)/(.*) $1/skin2/$2 [L] RewriteCond %{HTTP_HOST} skin3.example.com RewriteCond %{DOCUMENT_ROOT}$1/skin3/$2 -f RewriteRule ^(.*)/(.*) $1/skin3/$2 [L] </VirtualHost> The concept behind the rules is if the same filename exists in a subdirectory for that host, use it instead of the direct targeted file. This uses host based subdirectories at the lowest level, and not a top level subdirectory to separate content.

  • Strange results from OdbcDataReader reading Sqlite DB

    - by stout
    This method returns some strange results, and was wondering if someone could explain why this is happening, and possibly a solution to get my desired results. Results: FileName = what I'd expect FileSize = what I'd expect Buffer = all bytes = 0 BytesRead = 0 BlobString = string of binary data FieldType = BLOB (what I'd expect) ColumnType = System.String Furthermore, if the file is greater than a few KB, the reader throws an exception stating the StringBuilder capacity argument must be greater than zero (presummably because the size is greater than Int32.MaxValue). I guess my question is how does one properly read large BLOBs from an OdbcDataReader? public static String SaveBinaryFile(String Key) { try { Connect(); OdbcCommand Command = new OdbcCommand("SELECT [_filename_],[_filesize_],[_content_] FROM [_sys_content] WHERE [_key_] = '" + Key + "';", Connection); OdbcDataReader Reader = Command.ExecuteReader(CommandBehavior.SequentialAccess); if (Reader.HasRows == false) return null; String FileName = Reader.GetString(0); int FileSize = int.Parse(Reader.GetString(1)); byte[] Buffer = new byte[FileSize]; long BytesRead = Reader.GetBytes(2, 0, Buffer, 0, FileSize); String BlobString = (String)Reader["_content_"]; String FieldType = Reader.GetDataTypeName(2); Type ColumnType = Reader.GetFieldType(2); return null; } catch (Exception ex) { Tools.ErrorHandler.Catch(ex); return null; } }

  • Problem using the prependTo() in jQuery

    - by raulriera
    Hi all, I am having a problem trying to use the prependTo() function in jQuery... for some reason I can't get this to work $(" <div id="note178" class="note"> <div class="delete"><a href="/chart-notes/delete/178" onclick="$.ajax({ dataType: 'script', url: '/chart-notes/delete/178'}); return false;"><img src='/images/icons/delete.png'></a></div> <div class="timestamp">1 minute ago </div> <div class="content">ñasdas dasdasdasd conclusión</div> </div> ").prependTo(".notes").fadeIn("slow"); Although when doing it like this, it works fine $.ajax({ url:'/chart-notes/show/<cfoutput>#chartnote.id#</cfoutput>', success: function(data) { $(data).prependTo(".notes").fadeIn("slow"); // Scroll to the top of the annotations $('html, body').animate({scrollTop: $(".notes").offset().top}, 1000); // Clear the form $('#chartnote-notes').val(""); } }); The "data" response from that success function is the same <div id="note178" class="note"> <div class="delete"><a href="/chart-notes/delete/178" onclick="$.ajax({ dataType: 'script', url: '/chart-notes/delete/178'}); return false;"><img src='/images/icons/delete.png'></a></div> <div class="timestamp">1 minute ago </div> <div class="content">ñasdas dasdasdasd conclusión</div> </div> As before

  • What is the benefit of using ONLY OpenID authentication on a site?

    - by Peter
    From my experience with OpenID, I see a number of significant downsides: Adds a Single Point of Failure to the site It is not a failure that can be fixed by the site even if detected. If the OpenID provider is down for three days, what recourse does the site have to allow its users to login and access the information they own? Takes a user to another sites content and every time they logon to your site Even if the OpenID provider does not have an error, the user is re-directed to their site to login. The login page has content and links. So there is a chance a user will actually be drawn away from the site to go down the Internet rabbit hole. Why would I want to send my users to another company's website? [ Note: my provider no longer does this and seems to have fixed this problem (for now).] Adds a non-trivial amount of time to the signup To sign up with the site a new user is forced to read a new standard, chose a provider, and signup. Standards are something that the technical people should agree to in order to make a user experience frictionless. They are not something that should be thrust on the users. It is a Phisher's Dream OpenID is incredibly insecure and stealing the person's ID as they log in is trivially easy. [ taken from David Arno's Answer below ] For all of the downside, the one upside is to allow users to have fewer logins on the Internet. If a site has opt-in for OpenID then users who want that feature can use it. What I would like to understand is: What benefit does a site get for making OpenID mandatory?

  • Fix a 404: missing parameters error from a GET request to CherryPy

    - by norabora
    I'm making a webpage using CherryPy for the server-side, HTML, CSS and jQuery on the client-side. I'm also using a mySQL database. I have a working form for users to sign up to the site - create a username and password. I use jQuery to send an AJAX POST request to the CherryPy which queries the database to see if that username exists. If the username exists, alert the user, if it doesn't, add it to the database and alert success. $.post('submit', postdata, function(data) { alert(data); }); Successful jQuery POST. I want to change the form so that instead of checking that the username exists on submit, a GET request is made as on the blur event from the username input. The function gets called, and it goes to the CherryPy, but then I get an error that says: HTTPError: (404, 'Missing parameters: username'). $.get('checkUsername', getdata, function(data) { alert(data); }); Unsuccessful jQuery GET. The CherryPy: @cherrypy.expose def submit(self, **params): cherrypy.response.headers['Content-Type'] = 'application/json' e = sqlalchemy.create_engine('mysql://mysql:pw@localhost/6470') c = e.connect() com1 = "SELECT * FROM `users` WHERE `username` = '" + params["username"] + "'" b = c.execute(com1).fetchall() if not len(b) > 0: com2 = "INSERT INTO `6470`.`users` (`username` ,`password` ,`website` ,`key`) VALUES ('" com2 += params["username"] + "', MD5( '" + params["password"] + "'), '', NULL);" a = c.execute(com2) c.close() return simplejson.dumps("Success!") #login user and send them to home page c.close() return simplejson.dumps("This username is not available.") @cherrypy.expose def checkUsername(self, username): cherrypy.response.headers['Content-Type'] = 'application/json' e = sqlalchemy.create_engine('mysql://mysql:pw@localhost/6470') c = e.connect() command = "SELECT * FROM `users` WHERE `username` = '" + username + "'" a = c.execute(command).fetchall(); c.close() sys.stdout.write(str(a)) return simplejson.dumps("") I can't see any differences between the two so I don't know why the GET request is giving me a problem. Any insight into what I might be doing wrong would be helpful. If you have ideas about the jQuery, CherryPy, config files, anything, I'd really appreciate it.

  • How can I bind a javascript dialog using Knockout?

    - by Brian
    I've got a list of data in an observableArray and I want to show it in a javascript dialog window (I'm using jQuery.blockUI if it matters). Unfortunately the dialog seems to come unbound after the page is loaded. The dialog initializes correctly (the data is displayed), but it isn't updating with changes. There are no Javascript errors and I've moved the binding to after the dialog is generated and added to the document (no effect). I've also tried calling ko.applyBinding on the main div that makes up the dialog but that, for some reason, causes part of the main page to hide (the DOM is there, but they are hidden). EDIT: I've created a project on jsfiddle that reproduces the problem. The main culprit seems to be wrapping the content of the dialog in a div. If I show the content directly it seems to work (of course I can't do that, the wrappers provide a common style for our dialogs). I'm recovering from the flu and could easily be missing something obvious, but I've been trying all day and nothing is coming to me. Any ideas?

  • Slow website load with CNAME, fast when using IP

    - by Nate Strandberg
    I setup two DNS servers on my network: ns1.byte-werx.com && ns2.byte-werx.com I can ping the DNS servers and get a fairly good response time, when I dig them I also get a fairly reasonable response, but any website I filter through them is painfully slow (an upwards of 20+ seconds) -- verifiable by performing a tracert or attempting to access the URL in a browser. The DNS servers are running CentOS 6.3 and BIND9 with 500MB of memory (I figure that should be more than enough?). I have a reverse look-up zone (1.168.192) along with two website zones (www.byte-werx.com and www.stayhomedental.com) If I access the websites using their IP the page loads nearly instantly so I do not believe the issue is with the hosting server, but that is running Ubuntu Server 12.04 and Apache2 with 12GB memory. Any thoughts? I do not have the named.conf file in front of me but I can edit this post to include it if you feel it would be useful. Thanks for any advice!

  • Rsync over NFS with QoS: How to view real transfer speed?

    - by Ian Mackinnon
    We have a bandwidth limit between a Linux server and a NAS, created using 'tc' with an IP filter. When writing to an NFS mount of the NAS, rsync claims a very high transfer speed for each file and then waits a long time before acknowledging that everything has finished. The total time taken is consistent with the QoS limit and the time taken by the same transfer over FTP. Why does the write to the NFS mount report higher transfer speeds than are actually happening over the network? How can I monitor the actual bandwidth of the transfer?
