    - by Techn0guy
    Okay so I have sowered the internet for a long time trying to solve my problem. I have a table with my whole site in it and would like for it to stretch to fit the user's web browser size. Here is all the site's code atm <body> <table width="100%" border="0"> <tr> <td width="525" rowspan="2"><img src="My Images/Speaker.png" width="525" height="772" ondragstart="return false" /> </td> <td width="697" height="16"> *Flash Video Here* </td> </tr> <tr> <td><img src="My Images/Vymil.jpg" width="822" height="597" ondragstart="return false"/></td> </tr> </table> </body> </html> Any helpful solutions would be greatly appreciated

  • Regularly update database without browser/user

    - by Chris M
    I currently have a MySQL database which I was hoping to use to store regularly updated data from a temperature sensor connected to the internet. I currently have a page that, when opened, will grab the current temperature and the current timestamp and add it as an entry to the database, but I was looking for a way to do that without me refreshing the page every 5 seconds. Detail: The data comes from an Arduino Ethernet, posted to an IP address. Currently, I'm using cURL to grab the data from the IP, add a timestamp and save it to the DB. Obviously only updates when the page is refreshed (it uses PHP). Here is a live feed of the data - http://wetdreams.org.uk/ChrisProject/UI/live_graph_two.html TL;DR - Basically I need a middle man to grab the data from the IP and post it to a MySQL Edit: Thanks for all the advice. There might be a little bit of confusion, I'm looking for a solution that (ideally) doesn't require a computer to be on at all (other than the Server containing Database). Since I'm looking to store data over long periods of time (weeks), I'd like to set it up and leave a script running on the server (or Arduino) that gets the temp and posts it to the Database. In my head I would like to have a page on the server that automatically (without any browser open, or any other prompting other than a timer) calls a PHP script. Hope that clears things up!

  • Flash browser game - HTTP + PHP vs Socket + Something else

    - by Maurycy Zarzycki
    I am developing a non-real time browser RPG game (think Kingdom of Loathing) which would be played from within a Flash app. At first I just wanted to make the communication with server using simply URLLoader to tell PHP what I am doing, and using $_SESSION to store data needed in-between request. I wonder if it wouldn't be better to base it on a socket connection, an app residing on a server written in Java or Python. The problem is I have never ever written such an app so I have no idea how much I'd have to "shift" my thoughts from simple responding do request (like PHP) to continuously working application. I won't hide I am also concerned about the memory and CPU usage of such Server app, when for example there would be hundreds of users connected. I've done some research. I have tried to do some research, but thanks to my nil knowledge on the sockets subject I haven't found anything helpful. So, considering the fact I don't need real time data exchange, will it be wise to develop the server side part as socket server, not in plain ol' PHP?

  • How to detect that cookies are disabled in browser with AngularJS

    - by user2943082
    I use an AngularJS in my current project and try to implement feature which detects does cookies are disable in browser. I have tried to use an AngularJS module "ngCookies" for resolve this issue. The main idea of this feature is to try to create some cookie, then check does this cookie was created and show message if it wasn't. But it didn't worked. Controller: someProject.controller('CookieCtrl', ['$scope', '$cookieStore', function($scope, $cookieStore) { $scope.areCookiesEnabled = false; $cookieStore.put("TestCookie", "TestCookieText"); $scope.cookieValue = $cookieStore.get("TestCookie"); if ($scope.someValue) { $cookieStore.remove("TestCookie"); $scope.areCookiesEnabled = true; } }]); View: <div class="main" data-ng-controller="CookieCtrl"> <div class="warning_message" data-ng-show="!areCookiesEnabled"> <span data-ng-bind="areCookiesEnabled"></span> </div> </div> Can anybody tell me where is my mistake?

  • Python Webkit browser's inspector is missing a few things

    - by NoBugs
    I'm using a Webkit browser inspector like this. When I run it in Ubuntu 12.10, I'm getting errors when using the inspector. For example: ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Go to line" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Filter" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Search Previous" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Search Next" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "a:" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "%d of %d" not found. (geany:2487): Gdk-CRITICAL **: IA__gdk_error_trap_pop: assertion `gdk_error_traps != NULL' failed ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Sources Panel" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Toggle breakpoint" not found. ** Message: console message: file:///usr/share/webkitgtk-1.0/webinspector/UIString.js @42: Localized string "Painting" not found. I also noticed the breadcrumb/slider bar doesn't show when you have the console in the lower half: I don't remember this in earlier versions, and when I use the GTK3 version (from gi.repository import WebKit etc) it has similar problem, and is even worse, scrollbars don't have arrows at top and bottom. Am I missing a step on initializing the Webkit inspector or English locale for it? I would like to debug this issue, but since the inspector object isn't a webview object, I'm not sure I can add an inspector to the inspector? (like how you can use F12 when inspector is its own window in Chrome/Chromium, which lets you debug that inspector). It should be possible, but maybe not with pyGTK?

  • Python script not working when run from browser directly

    - by splatterdash
    I'm trying to run this script: import re, os def build_pool(cwd): global xtn_pool, file_pool xtn, xtn_pool = re.compile('\\.[0-9a-zA-Z]{1,4}$'), [] file_pool = [files for files in os.listdir(cwd) if os.path.isfile(files) and xtn.search(files)] # Lists all the file extension in the folder for file in file_pool: if not xtn_pool.__contains__(xtn.search(file).group()): xtn_pool.append(xtn.search(file).group()) return xtn_pool.sort(), file_pool if __name__ == '__main__': import sys #if path is given, change working directory to path if len(sys.argv) >= 2: os.chdir(sys.argv[1]) build_pool(os.getcwd()) #if no path is given when running, do renaming in current folder else: build_pool(os.getcwd()) print('The folder contains the following extensions: ') for i in range(0, len(xtn_pool)): print(repr(i+1) + '.

')) xtn_pick = xtn_pool[opt-1] # Lists all the file with the chosen extension xtn_file_pool = [file for file in file_pool if file.endswith(xtn_pick)] print('There are {0} files with the {1} extension.'.format(len(xtn_file_pool), xtn_pick)) xtn_new = input('Input replacement extension: ') # The actual renaming process for file in xtn_file_pool: os.rename(file, file[:-len(xtn_pick)+1] + xtn_new) directly from my file browser (Nautilus), but for some reason it's not working. When I run it from terminal (python3 scriptname.py) it works fine as intended. But when I just click the script file in Nautilus, choose 'Run in Terminal', it always stops after asking 'Input replacement extension: '. How can I make this script run without using the terminal?

  • How to force client browser to download images from server rather using its cache

    - by anonim.developer
    Assume a simple aspx data entry page in which admin user can upload an image as well as some other data. They are stored in database and the next time admin visits that page to edit record, image data fetched and a preview generated and saved to disk (using GDI+) and the preview is shown in an image control. This procedure works fine for the first time however if the image changes (a new one uploaded) the next time the page is surfed it shows previously uploaded image. I debugged the application and everything works correct. The new image data is in database and new preview is stored in Temp location however the page shows previous one. If I refresh the page it shows the new image preview. I should mention that preview is always saved to disk with one name (id of each record as the name). I think that is because of IE and other browsers use client cache instead of loading images each time a page is surfed. I wonder if there is a way to force the client browser to refresh itself so the newly uploaded image is shown without user intervention. Thanks and appreciation in advance,

  • PHP download page: file_exists() returns true, but browser returns 'page not found'

    - by Chris
    I'm using PHP for a file download page. Here's a snippet of the problem code: if (file_exists($attachment_location)) { header($_SERVER["SERVER_PROTOCOL"] . " 200 OK"); header("Cache-Control: public"); // needed for i.e. header("Content-Type: application/zip"); header("Content-Transfer-Encoding: Binary"); header("Content-Length:".filesize($attachment_location)); header("Content-Disposition: attachment; filename=file.zip"); readfile($attachment_location); die("Hooray"); } else { die("Error: File not found."); } This code works absolutely fine when testing locally, but after deploying to the live server the browser returns a 'Page not found' error. I thought it might be an .htaccess issue, but all .htaccess files on the live server are identical to their local counterparts. My next guess would be the live server's PHP configuration, but I have no idea what PHP setting might cause this behaviour. The file_exists() function always returns true - I've checked this on the live server and it's always correctly picking up the file, its size etc., so it does have a handle on the file. It just won't perform the download! The main site is a Wordpress site, but this code isn't part of a Wordpress page - it's in a standalone directory within the site root. UPDATE: is_file() and is_readable() are both returning true for the file, so that's not the problem. The specific line that is causing the problem is: readfile($attachment_location) Everything up until that point is super happy.

  • How to disable SSLCompression on Apache httpd 2.2.15?

    - by Stefan Lasiewski
    I read about the CRIME attack against TLS Compression (CRIME is a successor to the BEAST attack against ssl & tls), and I want to protect my webservers against this attack by disabling SSL Compression, which was added to Apache 2.2.22 (See Bug 53219). I am running Scientific Linux 6.1, which ships with httpd-2.2.15. Security fixes for upstream versions of httpd 2.2 should be backported to this version. # rpm -q httpd httpd-2.2.15-15.sl6.1.x86_64 # httpd -V Server version: Apache/2.2.15 (Unix) Server built: Feb 14 2012 09:47:14 Server's Module Magic Number: 20051115:24 Server loaded: APR 1.3.9, APR-Util 1.3.9 Compiled using: APR 1.3.9, APR-Util 1.3.9 I tried SSLCompression off in my configuration, but that results in the following error message: # /etc/init.d/httpd restart Stopping httpd: [ OK ] Starting httpd: Syntax error on line 147 of /etc/httpd/httpd.conf: Invalid command 'SSLCompression', perhaps misspelled or defined by a module not included in the server configuration [FAILED] Is it possible to disable SSLCompression with this version of Apache Webserver?

  • Look Inside WebLogic Server Embedded LDAP with an LDAP Explorer

    - by james.bayer
    Today a question came up on our internal WebLogic Server mailing lists about an issue deleting a Group from WebLogic Server.  The group had a special character in the name. The WLS console refused to delete the group with the message a java.net.MalformedURLException and another message saying “Errors must be corrected before proceeding.” as shown below. The group aa:bb is the one with the issue.  Click to enlarge. WebLogic Server includes an embedded LDAP server that can be used for managing users and groups for “reasonably small environments (10,000 or fewer users)”.  For organizations scaling larger or using more high-end features, I recommend looking at one of Oracle’s very popular enterprise directory services products like Oracle Internet Directory or Oracle Directory Server Enterprise Edition.  You can configure multiple authenicators in WebLogic Server so that you can use multiple directories at the same time. I am not sure WebLogic Server supports special characters in group names for the Embedded LDAP server, but in this case both the console and WLST reported the same issue deleting the group with the special character in the name.  Here’s the WLST output: wls:/hotspot_domain/serverConfig/SecurityConfiguration/hotspot_domain/Realms/myrealm/AuthenticationProviders/DefaultAuthenticator> cmo.removeGroup('aa:bb') Traceback (innermost last): File "<console>", line 1, in ?

Follow the instructions here, being sure to change the authentication credentials to the Embedded LDAP server to some value you know, as by default they are some unknown value.  You’ll need to reboot the WebLogic Server Admin Server after making this change. Now configure JXplorer to connect as described in the documentation.  I’ve circled the important inputs.  In this example, my domain name is “hotspot_domain” which listens on the localhost listen address and port 7001.  The cn=Admin user name is a constant identifier for the Administrator of the embedded LDAP and that does not change, but you need to know what it is so you can enter it into the tool you use. Once you connect successfully, you can explore the entries and in this case delete the group that is no longer desired.

  • Most basic, low power home surveillance system

    - by cbp
    I am thinking of setting up a simple but effective surveillance system for my house that is: Very low powered (preferably no PCs left running out of stand-by mode) Cheap. When motion (or sound) is detected, I would like it to: Send an email/phone alert to me Record and upload video to the web (in case they steal the camera) So I imagine a system where I leave a netbook PC in stand-by mode and have it woken up by a motion detector. This initiates software to send alerts and periodically upload recorded video to the web. The software part is easy for me, but I'm not really a gadget-man so I'd like some advice on using a motion sensor of some sort to wake up the PC. Does anyone have some good advice? I know there are a couple of questions dealing with this topic already (see here: http://superuser.com/questions/3054/looking-for-a-moderately-priced-home-surveillance-setup, and here: http://superuser.com/questions/2929/can-you-suggest-a-great-home-security-setup-anti-burglars-e-t-c) - I am seeking more specific information with this question.

  • Controlling the fontsize across multiple browsers

    - by Matthias
    Hello, I've got 3 browsers on my WinXPpro: Firefox 3.5.2, Opera 10 and IE 7. Alle pages are displayed fine in FF. Opera and IE seem to have a very similar issue: Both upsize fonts eventhough zoom mode in both browsers is set to 100%. I tend to believe that this might be a system-wide setting, somewhere. Does anyone know this problem? Thanks in advance.

  • Getting ERR_DNS_FAIL when loading a local webserver page?

    - by NickA
    When I go to a page hosted on a machine on a local network, I get a "The page cannot be found" error with "ERR_DNS_FAIL" in the title. Any ideas what this is or why I am getting it on my computer? I've tried in Firefox, IE and Chrome. Other computers on the network load the page just fine. I'm pretty sure it is from the hostname. I am able to access the page if I browse to it using the IP of the machine. However, it has two hostnames and both are giving the ERR_DNS_FAIL error. I tried restarting the browsers or rebooting the machine, but neither helped. EDIT: ISSUE RESOLVED ON ITS OWN!

  • Is it a bad idea to run an asp.net app pool with the same identity as IIS's anon user?

    - by Andrew Bullock
    Subject says it all really, Thinking on security terms, I want to give each site on my server its own user account, so that they can't access each other's data. I also want to use integrated authentication for sql so i dont have any passwords knocking about in connection strings. Is it a bad idea to use the same account for the app pool identity and the anon user account for iis (im interested in answers for both v6 and 7)? Edit: ive seen this post describing how IIS7 allows you to automatically use the same account, but the question of whether its a good idea or not remains ;) If so, why? Thanks

  • rr.com appended to URL and I don't know why

    - by Steph
    I've been having some pretty bad and intermittent internet connectivity issues. I keep getting timeouts on my browsers, or what appears to be timeouts on my browsers. In Chrome it's generally error 21. FF it times out. And so on. While this is happening, I can go into the command line and ping or traceroute the same domain and it works fine. I use my cellphone on the same network and it's fine connecting to the same domain. And when it fails, it's all domains that are down in all browsers, chrome, FF, etc. I also noticed that when I try to connect to 192.168.1.1 it says in chrome did you mean www.192.168.1.1rr.com but when I enter https://192.168.1.1 it's fine. It only seems to do this in Chrome. This is making me think I have a virus. I did some researching about something called road runner, but I can't find any related traces. I also ran a full virus scan using nod32 (eset) and nothing. Any suggestion or help would be greatly appreciated. The intermittent loss of total internet access is really annoying and I'm worried about why it's trying to append the rr.com domain in Chrome. I suspect I'm dealing with two different issues, but you never know. Also for the DNS I'm using Google's DNS servers, the famous 8.8.8.8 and 8.8.8.4

  • Server Administration

    - by Kassem
    Hi everyone, My client asked me for a job description of a system administration because I might be assigned this position along with the other guy I'm working with. To be honest, I do not know much about a System Administrator's job but I'm willing to learn. Questions: What are the security requirements of a server? * What are the key responsibilities in a system admin's job description? What are some of the day to day tasks of a system admin? What is the average monthly salary of a system admin? Note: I will be working inside a Windows environment. But your replies do not necessarily need to be constricted to a Windows environment. (*) Other software I know will be required are: Windows Server 2008 IIS 7.0 MS SQL Server .NET 4.0 Runtime Let me know if there are other things I should be aware of as well. Thanks!
