HI,
Is there any tool which can easily change color of an image?
I heard of gimp. But I can't figure out how to use it to change color of an image (e.g. change the color from white to blue).
I'd like to record what I hear coming out of the main audio jack on my Mac. Nothing fancier than that. I'm aware of Audio Hijack Pro but that really does much more than I'm looking for and comes with a steep price tag. If it's the only tool that can do the job that's fine but I was hoping to find something that simply captured all audio coming from the computer and dumped it to a file.
Thanks in advance!
I have a FreeNAS server with 3 x 2 To disks in raidz1. I would expect to have about 4 To of space available. When I run zpool list I get:
[root@freenas] ~# zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
main_volume 5.44T 3.95T 1.49T 72% ONLINE /mnt
I was expecting a size of 4 To.
Also, used space as reported by zpool list does not match what's reported by du:
[root@freenas] ~# du -sh /mnt/main_volume/
2.6T /mnt/main_volume/
There are quite a few things that I dont yet completely understand about ZFS. But at the moment I am mostly worried that I misconfigured my system and that I dont have any storage redundancy. How can I make sure I did not do an horrible mistake ...
For the sake of completeness, here is the output of zpool status:
[root@freenas] ~# zpool status
pool: main_volume
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
main_volume ONLINE 0 0 0

Considering a machine with IIS 7.5/PHP 5.2/asp.net and mysql/MSSQL available, which webmail would you pick?
Don't think it's relevant but the mail server is installed on localhost, and is hmailserver.
If it's one using asp.net it'd be a bonus, but PHP is ok as well and probably offers more choices.
"Client side" look and feel definitely needed, flash/silverlight/ajax not a problem.
I have also seen this question, but being asked almost 2years ago and being focused on php webmails, I thought that some better option could've been released in the meantime.
I'd like to use Markdown for documents to be exchanged with a colleague of mine. The ideal workflow would be IMHO editing the source in any plaintext editor while simultaneously viewing it in a browser. The client viewer should be able to redraw the text after each save automatically, and ideally even always switch to the most recent source file (so I don't need to navigate there manually).
It'd be nice if I could (was allowed) modify the viewer a bit, things like using trailing spaces for line breaks are really terrible (I don't see them, my editor strips them, git complains about them, etc.).
I'm interested in a software capable of this and easy to modify, and also in your opinions on the described workflow.
Hi, I'm looking for a way to minimize the net traffic use with my netbook mobile internet connection. Recently I managed to install Opera Mini on the XP and the opera approach of compressing the data helped a lot. But I would like to do the same with my favorite browser using http proxy that compress the data "on the fly". But searching for "compression proxy servers" I could not find any working host/port links. Is it a brand-new technology and therefore expensive or rarely available?

Any suggestions?
The tablespace in Oracle 10g is almost 100% used.
Size (MB) = 571,768.0
Used (MB) = 571,534.0
I just deleted (and committed) thousands of records in a table that belongs to a schema associated with that tablespace. Surprisingly, no space was freed up according to the Tablespaces page on Enterprise Manager.
Question: is there anything that I need to do to force Oracle to release the space corresponding to the deleted records?
I'm a dyslexic and i generally use arial for most things, since its probably the most readable font for me. However i'd like to have a fixed width font with similar charecteristics (sans serif, distinct, 'simple' characters etc) since some things break with non fixed width fonts, but at the same time, most of the 'standard' fonts are harder to read for me- any suggestions?
I'm developing a Nagios plugin in Perl (no Nagios::Plugin, just plain Perl). The error condition I'm checking for normally comes from a command output, called inside the plugin. However, it would be very inconvenient to create the error condition, so I'm looking for a way to feed test output to the plugin to see if it works correctly.
The easiest way I found at the moment would be with a command line option to optionally read input from a file instead of calling the command.
if($opt_f) {
open(FILE, $opt_f);
@output = <FILE>;
close FILE;
}
else {
@output = `my_command`;
}
Are there other, better ways to do this?
I'm hoping to implement a VPN whereby about 200 concurrent users can log in to briefly access my network. I had a look at OpenVPN and this seemed excellent, but was hoping that there would be a less costly option on a per-concurrent-user basis.
I've no need for particularly strong security, and my only other requirement is that I would need to be able to add users in bulk via csv or similar.
Does anyone have any suggestions?
I've finally decided that pen and paper/whiteboards are not up to the job as my workload increases so I'm looking for a good task tracking system.
I need something that can track tasks in categories (projects) and allow me to assign priority to each task.
I've tried iTeamWork which requires projects to have an end time which is no good for me as at least one of my projects is ongoing. I also tried Teamly which was required tasks to be set to a specific day which is no good as tasks sometimes take more than a day and I would like them organised by priority rather than specific days.
Preferably looking for something hosted but I'm happy to install on our servers if it supports PHP/MySQL.
Oh, and an iPhone client would be the icing on the cake!
Can anyone recommend anything?
We have Google apps in our company for mail delivery, our business can't pay the business version yet, however, we need to control the attachment types that employees download.
We recently switched from another hosting provider who recomended us to plug Google Apps for mail when we moved the domain, we had a firewall before which was able to prevent certain file types to be downloaded.
I know the business version has section for filtering mail (postini services). Is there a hack around my problem? Anyone ever had this problem? Thank you!
UPDATE:
The main problem is gmail apps uses ssl connection, can this be changed ? how can i get the firewall to filter files only allowing *.doc, *.xls y *.pdf.
At the beginning of this year I took a VPS for my website because I was running against the resource limits from a shared hosting.
Here are the things I know:
2GB memory, with 1GB swap
Debian X64 server ED installed
Software running on the webserver:
mysql
apache
postfix
pop3
imap
amavisd
clamd
cron
fail2ban
munin-node
pure-ftpd
spamd
nginx
Now for the setup:
Nginx listens on port 80 and handles the static files, the php side is done by apache2 running mod_php in combi with apc(no var caching!).
Iam using a pretty 'busy' drupal and phpbb stack on the server, for drupal iam using boost and authcache to handle of the server load with a pressflow stack. phpbb is just phpbb3 with some mods installed, but has at max 30 users online at a time..
The problem is that its staring to use the swap after a few days after a reboot and thus the site becomes slower.
I'v added pictures of monit and munin, so maybe somebody can help me out...

I have used Visio to map out my network structure, and have used the export function to create an HTML page that is searchable by IP, hostname etc. This is a really nice tool and I use it often.
However, I would like for users who do not use Internet Explorer to be able to use the search features. What are some alternatives to Visio here? I want to draw a network diagram where objects are searchable.
Thanks!
Hi, I know in these days this is very stupid question, but for study purposes. I read that when PC starts, CPU is set to read adress just under the 4GB. There should BIOS be mapped to by memory controller.
My question is, in old days, had disabling BIOS shadowing actually freed some RAM for you? I mean, even when BIOS was not shadowed to RAM directly, still adresses for BIOS MMIO access were wasted. And when you cant adress it, its like there is no extra space gained.
I have several PDFs made up of book pages' scans. The scans are made from two pages at a time and some of these scans are skewed, making text appear slightly tilted.
I'm looking for a tool that could allow me to do an automatic optimization by deskewing the scans without losing readability. I've found the GPL software briss to crop the scans in order to have a 1:1 page ratio instead of 2:1, but I don't have any tool to deskew the pages.
I stumbled upon unpaper, another open source tool that seems perfect for what I want to do, but that tool is Linux only and it doesn't work on PDF files directly.
Any hint is appreciated.
Thank you.
I'm reading about Google App Engine.
I'm creating a bunch of simple dynamic websites in java.
I'm considering to use Google App Engine and setup my clients' website on it.
In this way I've only to register a domain www.myclietdomain.com and then point that to the GoogleAppEngine application...
In this way I plan to avoid hosting costs.
Infact I'm paying even for hosting few static html pages...
Do you think that is possible to use Google App Engine for this scope?
Is there something which may:
Play music, at the very least in MP3-format
Play video in various codec's
Helps in recording video of shows from TV through a TV-in card
Helps in organizing music and videos
Works with a keyboard and mouse
Additional pluses are:
If it also is possible to browse the web through it, or at least start the web browser
Has some games. Maybe through MAME or some other emulation like SNES or something.
If it's also possible to control it through a game pad.
Hello All,
I'm in the mid of researching for one of the best hosting control panels. The server I run is Ubuntu and I have some experience with ISPConfig 2 & 3. Since I haven't explored any others available, what are the recommended ones for an Ubuntu server?
I asked because I find that there seems to be some disabling and modifications required for an Ubuntu server if I need to use ispconfig which causes the server to change its actual way of running. It's quite good though, but any more recommended ones ?
Something more organic? which doesn't require much breaking and changing.
I'm not asking for the simple one, I don't mind going extra mile to install a powerful one but just try sticking with most Ubuntu's conventions will be an ideal one for me.
And of course, if there happens to be something that meets the requirement as mentioned "Ubuntu conventions" and also simple to install at the same time, that'd be a bonus.
Thanks in advance.
Is there any simple & freeware program to fix corrupted zip files for windows platform ? I've lot of corrupted zip files and would like to recover some of the files from it
