  • Why won't the floppy mount?

    - by dboarman-FissureStudios
    The 1.44Meg floppy won't mount in my Nautilus file browser. When I try to mount it, it says there is no media in the drive. Yet, I can write to the floppy through the terminal using the 'cp' command. I can enter the command: mount -t ext2 /floppy and it mounts. I have also run a check and the disk itself is 100% clean. So, why can't I get the nautilus browser to open up the floppy? Is there a way to see the actual floppy from the terminal?

  • Postgres error messages in Apache error log

    - by Warren Pena
    I'm running Apache 2.2, PHP 5.2, and Postgres 8.2 on Windows, and I'm seeing something funky in Apache's error.log file. Occasionally, I'll see the message "row number -1 is out of range 0..-1" pop up over and over. Unlike all the other lines in that log file, there's no timestamp or log level. Just that exact string. Googling around, it appears that message is, character for character, a common Postgres error message, but is not an Apache error. I've seen it happen multiple times, and on several different servers. I can't seem to reproduce it, though. I've tried throwing all sorts of error ridden database queries and result set inquiries at Postgres via PHP, and none of them seem to trigger that line being written to the log file. Is it possible for Postgres errors to be ending up in my Apache log file, and if so, how? What would trigger an error message like that? Thanks!

  • php APC uptime problem

    - by hamlet
    I am on LAMP with Alternative PHP Cache. It worked fine until yesterday when I updated the website and changed a few mySQL queries (I don't see the how it would affect APC opcode cache) Today I see that the load has increased on the server and I see in Alternative PHP Cache, that the uptime of APC is somewhere around 15 minutes then it gets restarted. At this point the APC cache is only about 20% full of the available 30Mb. Using for opcode cache only. During this 15 minutes the cache works fine (99,8% cache hits). After this unwanted restart the APC cache is empty. Why is it restarting? Where can I find the logs for it? Thanks, Hamlet

  • what are good blogs to read relating java, spring, hibernate, maven?

    - by c0mrade
    To continue to question further I'm more interested in blogs, websites who once in a while release a tutorial, tip or best-practice on the topics I mentioned. For ex : http://net.tutsplus.com/ is very good website to follow if you wanna learn about or upgrade your knowledge about CSS, HTML, Javascript, PHP .. Is there a website like this for Java and related technologies?

  • Single django instance with subdomains for each app in the django project

    - by jwesonga
    I have a django project (django+apache+mod_wsgi+nginx) with multiple apps, I'd like to map each app as a subdomain: project/ app1 (domain.com) app2 (sub1.domain.com) app3 (sub3.domain.com) I have a single .wsgi script serving the project, which is stored in a folder /apache. Below is my vhost file. I'm using a single vhost file instead of separate ones for each sub-domain: <VirtualHost *:8080> ServerAdmin [email protected] ServerName www.domain.com ServerAlias domain.com DocumentRoot /home/path/to/app/ Alias /admin_media/ /usr/local/lib/python2.6/dist-packages/django/contrib/admin/media <Directory /home/path/to/wsgi/apache/> Order deny,allow Allow from all </Directory> LogLevel warn ErrorLog /home/path/to/logs/apache_error.log CustomLog /home/path/to/logs/apache_access.log combined WSGIDaemonProcess domain.com user=www-data group=www-data threads=25 WSGIProcessGroup domain.com WSGIScriptAlias / /home/path/to/apache/kcdf.wsgi </VirtualHost> <VirtualHost *:8081> ServerAdmin [email protected] ServerName sub1.domain.com ServerAlias sub1.domain.com DocumentRoot /home/path/to/app Alias /admin_media/ /usr/local/lib/python2.6/dist-packages/django/contrib/admin/media <Directory /home/path/to/wsgi/apache/> Order deny,allow Allow from all </Directory> LogLevel warn ErrorLog /home/path/to/logs/apache_error.log CustomLog /home/path/to/logs/apache_access.log combined WSGIDaemonProcess sub1.domain.com user=www-data group=www-data threads=25 WSGIProcessGroup sub1.domain.com WSGIScriptAlias / /home/path/to/apache/kcdf.wsgi </VirtualHost> My Nginx configuration for the domain.com: server { listen 80; server_name domain.com; access_log off; error_log off; # proxy to Apache 2 and mod_wsgi location / { proxy_pass http://127.0.0.1:8080/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } Configuration for the sub.domain.com: server { listen 80; server_name sub.domain.com; access_log off; error_log off; # proxy to Apache 2 and mod_wsgi location / { proxy_pass http://127.0.0.1:8081/; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_max_temp_file_size 0; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } } This set up doesn't seem to work, everything seems to point to the main domain. I've tried http://effbot.org/zone/django-multihost.htm which kind of worked but seems to have issues with loading my css,images,js files.

  • Oracle tuning optimizer index cost adj and optimizer index caching

    - by Darryl Braaten
    What is the correct way to set the optimizer index cost adj parameter for Oracle. As a developer I have observed huge performance improvements as this parameter is lowered. Common queries are reduced from 2 seconds to 200ms. There are lots of warnings on the net that lowering this value will cause dire issues with the database, but no detail is given on what will start going wrong. I am currently only seeing only an upside, much improved application performance and no downside. I need to better understand the possible negative repercussions of adjusting these parameters.

  • Embedded Javascript in Master Page or Pages That Use Master Page throw "Object Expected Error"

    - by Philter
    I'm semi-new to writing ASP.Net applications using master pages and I've run into an issue I've spent some time on but can't seem to solve. My situation is that I have a master page with a structure that looks like this: <head runat="server"> <title>Test Site</title> <link rel="Stylesheet" type="text/css" href="Default.css" /> <script type="text/javascript" language="javascript" src="js/Default.js" /> <meta http-equiv="Expires" content="0"/> <meta http-equiv="Cache-Control" content="no-cache"/> <meta http-equiv="Pragma" content="no-cache"/> <asp:ContentPlaceHolder ID="cphHead" runat="server"> </asp:ContentPlaceHolder> </head> <body> <form id="form1" runat="server"> <div id="divHeader"> <asp:ContentPlaceHolder ID="cphPageTitle" runat="server"></asp:ContentPlaceHolder> </div> <div id="divMainContent"> <asp:ContentPlaceHolder ID="cphMainContent" runat="server"></asp:ContentPlaceHolder> </div> </div> </form> </body> I then have a page that uses this master page that contains the following: <asp:Content ContentPlaceHolderID="cphHead" runat="server"> <script type="text/javascript" language="javascript" > function test() { alert("Hello World"); } </script> </asp:Content> <asp:Content ContentPlaceHolderID="cphMainContent" runat="server"> <fieldset> <img alt="Select As Of Date" src="Images/Calendar.png" id="aAsOfDate" class="clickable" runat="server" onclick="test();" /> <asp:Button runat="server" CssClass="buttonStyle" ID="btnSubmit" Text="Submit" OnClick="btnSubmit_Clicked"/> </fieldset> </asp:Content> When I run this page and click on the image I get an "Object Expected" error. However, if I place the test function into my Default.js external file it will function perfectly. I can't seem to figure out why this is happening. Any ideas?

  • Any way to colorize specific days in FullCalendar?

    - by Bryan Field-Elliot
    Using FullCalendar, is there any way I can programmatically colorize specific days differently than the rest of the days? For example, in the "month" or "week" views, I'd like to colorize days with no events on them "red", and days with some events (but not yet a full schedule) "yellow". Days with a full schedule would be colorized normally (white background). Are there any callbacks or CSS tags I can take advantage of to add this behavior? Thank you.

  • Is there any descent open-source search engine solutions?

    - by Nazariy
    Few weeks ago my friend asked me how hard is it to launch your own search engine service with list of websites that suppose to be crawled time to time. First what come at my mind was Google Custom Search however pricing policy is quite tricky and would drain your budget if you reach 500K queries per year. Another solution I found here was SearchBlox, which can be compared to Google Mini service. It's quite good solution if you planing to cover search over small amount of websites but for larger projects it is not very handy. I also found few other search platforms like Lucene, Hadoop and Xapian which seems to be quite powerful solutions to reach Google search quality, and Nutch as a web crawler. As most of open-source projects they share same problem, luck of comprehensive guidance of usage, examples and it's expected that you are expert in this subject. I'm wondering if any of you using this solutions, which of them would you recommend, and what should I be aware of?

  • TrueCrypt with ext2/3 partition write access under Mac OS X Snow Leopard ?

    - by ssc
    I'm using a TrueCrypt volume with an ext3 partition under Snow Leopard with MacFUSE. I can mount ordinary (unencrypted) ext3 partitions read/write from the shell by adding command line arguments as shown in "Mounting ext3 in Snow Leopard…". However, TrueCrypt mounts the partition read-only and I don't see any way to 'sneak in' the required additional arguments. How do I mount it read/write? I was hoping for a similar solution as for mounting NTFS, but diskutil info /Volumes/my_volume/ does not return a UUID; it does tell me Read-Only Media: No Read-Only Volume: Yes though...

  • Bash Script to Back Up Backs Up Itself

    - by Jay LaCroix
    I have the following bash script that creates a tar.gz of my filesystem on a Kubuntu PC. The problem is, that it also tries to backup the tar.gz backup file, even though I am storing the backup in /tmp and omitting /tmp from the backup. I am wondering why it's backing up the file in /tmp even though I told it not to. #!/bin/bash # init DATE=$(date +20%y%m%d) sudo tar -cvpzf /tmp/`hostname`_$DATE.tar.gz \ --exclude=/proc \ --exclude=/lost+found \ --exclude=/sys \ --exclude=/mnt \ --exclude=/media \ --exclude=/dev \ --exclude=/tmp \ --exclude=/home/jlacroix/Desktop \ --exclude=/home/jlacroix/Documents \ --exclude=/home/jlacroix/Music \ --exclude=/home/jlacroix/Pictures \ --exclude=/home/jlacroix/Projects \ --exclude=/home/jlacroix/Roms \ --exclude=/home/jlacroix/Videos \ --exclude=/home/jlacroix/.VirtualBox\ VMs \ --exclude=/home/jlacroix/.SpiderOak \ / scp /tmp/`hostname`_$DATE.tar.gz jlacroix@Pluto:/share/Recovery/Snapshots sudo rm /tmp/`hostname`_$DATE.tar.gz

  • VirtualBox / Ubuntu 10.04 Server

    - by SevenCentral
    I created a virtual machine using VirtualBox 3.2 and Ubuntu Server 10.04 x64. Everything works fine. I logged in. I mounted the VBoxGuestAdditions.iso file. However, I can't for the life of me find where in the operating system this was done so I can get the additions installed. I've tried /media, /cdrom, /mnt, etc... I'm obviously new at this. Can someone help figure out how to install the guest additions and how to locate the mounted file? Thanks.

  • Can the NVIDIA ION chipset handle streaming and gaming reasonable well?

    - by true_gritt
    I'm considering getting a small-footprint "nettop" computer to use as a home theater PC with my Samsung LN40A550 HDTV. I've been looking at systems like the AS Rock ION HT330, the Acer AspireRevo 3610, or the Asus EeeBox PC EB1501. These are all systems with NVIDIA ION chipset (Intel Atom N330 dual core CPU + NVIDIA GeForce 9400 GPU). Is the NVIDIA ION chipset powerful enough to support media streaming at HD resolutions (e.g. via Boxee, Hulu, Netflix) and casual gaming (e.g. World of Warcraft, Madden NFL) reasonably well without herky-jerky video output?

  • Using Linode as a proxy server wrapped in DNS to bypass paid internet services

    - by snihalani
    I have a linode server that I use for development. I was thinking of using that as a proxy server. I have noticed that most paid connections allow DNS queries but don't allow http until I pay them. I verified this by flushing my dns cache and nslookup some random websites. How do I create a proxy server that allows me to may be wrap my packets from my computer in DNS packets, relay to my linode server with ssh key authentication and act as a broker? Thanks.

  • C++ (And other languages) - Learning from source code examples.

    - by Gabe
    I found that the most effective way for me to learn html and css was to simply find a site, right click, view the source code, and see how it worked. I'm in the process of learning c++ and I think examples/source code to look through would help me a good deal. So, how can I do this? Are there online sites that serve this purpose? Any other recommendations on learning would be great, too.

  • Can someone recommend a Compact Flash card to be used as a boot disk/fixed disk.

    - by Hamish Downer
    I have an early Acer Aspire One netbook, and the flash drive is really slow at writing. I've taken it apart to add more RAM, but I've pretty much stopped using it. I've read about people replacing the SSD with a Compact Flash card and a CF to ZIF adapter but I've also read about some Compact Flash cards where the manufacturer has permanently disabled the boot flag to stop people doing this kind of mod. (Can't find the link any more though). (Although I have just found some info about CF cards that says "Most CompactFlash cards by default identify themselves as removable media instead of fixed disk" and that this is an issue for Windows. So my most specific question is: can someone recommend a compact flash card that does allow the boot flag to be set and to be set as Fixed Disk? Please say whether you've done it yourself, or just heard about it from someone else. Beyond that, is this generally a problem?
