I have two almost identical images of the same size that I want to compare. I'd like to over-lay them one on top of the other and vary each image's transparency so that I can compare them. Anyone know of any software that does this?
View 4 RepliesMy company requires a proxy server that requires a manual configuration to use. Many Ubuntu apps, however, do not respect the HTTP proxy settings.Is there anyway to modify my local firewall settings to automatically forward IP traffic to the company proxies in the same way a transparent proxy might work?Would I need to set-up my own local, transparent squid proxy which itself forwards to the company proxy?
View 1 Replies View Relatedfollowing on from [URL] I was having a little think about how to make this concept more secure. its easy enough to separate known and unknown clients out via MAC address. but that system is easier to break than it is to set up either, sniff out a mac address already connected to the system, and spoof that address.or, more simply, set a static IP on your wifi device, and avoid the redirection completely. so, is anyone aware of a relatively straight forward setup that would allow me to identify clients on my network without relying on MAC address, would more forcefully separate out known and unknown hosts (vlan??). As well as doing so without alerting them to the fact, and without requiring known hosts to do anything special, or install software. Or requiring any more hardware than I have already. (hardware = a debian box with 2 NIC's acting as a gateway between all internal network, and the billion router which handles the outside world not getting in, and a WAP attached to the internal side of the network. also somewhere I have a wifi card that I could attach to the server to replace the AP) I assume some sort of authentication mechanism is required, but I dont know much more past that.

screen -x lftp -X hardcopy /dev/fd/1
screen -x lftp -X hardcopy /dev/stdout
It works if I use a regular file instead, so why doesn't it print to stdout when I use /dev/fd/1? I do this with other applications don't have an option to write to stdout and it works, so what does GNU/Screen do that makes it not work?
I'm trying to setup iptables to send web (tcp?) traffic through Squid and Privoxy transparently (to save having to setup everything per browser and hoping they honor their settings). I know I have done this before but I can't find the old config nor remember the exact options needed to do this.What I am wanting specificially is for Privoxy to grab the data as it leaves the browser, do its thing then pass it on to Squid before sending it down the line, then doing the same incoming (Privoxy -> Squid -> requesting app).

View 6 Replies View RelatedOnce I launch google chrome
14.0.792.0 (Developer Build 88942 Linux) Ubuntu
(problem happens across various chrome versions and firefox too)
and I visit a site with graphics, still image or ....., I get a screen overlay of the website image positioned near top left of my monitor which overlays its graphics on top of windows of other applications. Interestingly, when I kill chrome the image disappears, then reappears on re-launch of chrome. Somehow chrome is controlling the rendering of its video memory, from killed tabs, outside of its own window.
This I have seen for firefox as well. Its been happening for few months, not on every browser launch but daily nonetheless. The video corruption also prevents mouse cursor cut N paste of text on any application which happens to have its window overlayed in this manner.
I have all the latest updates
ubuntu 11.04
nvidia driver 270.41.19
screen captures of offending overlay do not show up, though I could photograph my screen if need be. Have stopped using beta chrome daily builds, now using default google chrome to verify whether symptoms disappear.
I see no apparent errors in system log or X server log
I have followed a few guides on using video overlays to obtain a watermark. i am suppose to use the Bluescreen video effect along with the composite transition in kdenlive.
I run the following versions of software:
lucid lynx 10.04
FFMPEG compiled from svn
x264 compiled from git
Kdenlive 7.7.1
Kino 1.3.4
melt 0.5.6 from a PPA
Medibuntu repos
My video I want the watermark over is a kino captured file which is dv avi type 2 (open dml).I have done Bluescreen video effect along with the composite transition but the video clip which the video watermark plays on top of ends up getting darker. for the bluescreen color i have chosen red which is the closest red i could pick next to the spinning logo. the lighting changes on it and gives it an undesirable effect as far as how dark it it. i tried other colors but then the logo either disappears or the spinning logos black video background covers up my video. the reason for my "video" watermark is because it is a spinning logo (not a picture) which can be obtained in .mp4 format here:[url]
My goal is to put that on top of some xbox 360 modern warfare 2 gameplay. i haven't uploaded an example of how dark it makes the footage look yet but it does.
I am running Linux from a DVD, not installed. I am not good with installing software, but since the DVD cannot be corrupted, I am content to operate this way. Lately, I have been having problems that previously did not occur. When I try to click on the checkbox to get rid of emails, it doesn't register in most cases, or when it does, I am clicking multiple times so it registers twice, meaning it is unchecked again. Even more frustrating is some issues that are affecting my ability to update my business. I am trying to modify spreadsheets (text not calculations).
Whenever I try to click & drag to select something to change, it keeps jumping around to select only some of what I want, something else or some combination of the 2. When I try to copy and paste several fields from 1 column to another, everything from the several fields in the source column ends up together in the last field in the target column. I am also trying to download some images from a website. There is a single column of links to the images. I have to click on the link to get to the image in order to copy it, then back out to continue looking for more links to do the same.
My computer keeps jumping back 2 steps, then forward 2 steps, and sometimes I lose my place in that list. I could deal with it if it were a small number of links, but this is a list of probably close to 20,000 links. Again, i am operating off of a live DVD so this should not be corruptible, but this has just started happening, and has been an issue the last several sessions.
Unsure of what caused this but please reference the screenshot to see my problem. I'm not using any special graphics driver, just whatever the distro decided to use upon install.

The problem with this is that each image is then stretched to fit on one page, whereas I would like to keep the original dimensions of the images and put as many as possible on one page in the PDF file before moving on to another page.
I just set-up my fedora-14 live usb on an 8gb usb hard drive but I see the space left on '/' is less than 800mb (I created a 3.5gb persistent file) like so:

--overlay-size-mb 3500 Fedora-14-x84_64-Live-Desktop.iso /dev/sdc1
but I still don't have much space to install programs.
Is there a way to trick yum into installing programs under /home/liveuser/programs instead ?:

I finally dropped Gnome and am trying to put together my own custom Xclient-style desktop, with Xmonad as my WM. My question: Do any of the desktop widget systems out there support fixed, transparent overlay of the screen? My idea was something like this: I want, for example, my desktop clock widget not to be stuck in some dock taking up screen space; but instead, it would overlay the screen in one corner, with its background transparent. That way I could always see it, but it wouldn't gobble up screen space in a separate menu bar.
View 2 Replies View RelatedI am trying to create a LiveUSB with persistent overlay. Here is what I am doing ...
1. I create my own LiveCD image.
# LANG=C livecd-creator --config=centos-livecd-desktop.ks --fslabel=CentOS-5.4-<arch>-LiveCD
2. Insert and format the USB (I'd tested FAT and EXT).
3. Create the filesystem on the USB.
# livecd-iso-to-disk --overlay-size-mb 2500 CentOS-5.4-i686-LiveCD.iso /dev/sda1
4. Test it.
# umount /dev/sda1
# sudo kvm -hda /dev/sda1 -m 256 -vga std
The process seems to be fine but when I boot I receive the message: "Unable to find persistent overlay using temporary" complaining about failing mount /overlay.
If I watch inside LiveOS/ I can find the overlay file: overlay-jimezam_lab-d9d04988-3b00-4a2d-8207-43007ac71ef1.
I am just spent half an hour hunting for a thing that should be totally available already:USB install images of Ubuntu, knoppix and all the others.And, the only good way are so far complicated tutorials where you extract the stuff from an CD image. Why??Hasn't everybody notices that CDs/DVDs are vanishing big time? That more and more systems don't have the readers anymore? Instead of following a 10 point instruction list, it would be nice to just be able to download a Ubuntu 8.10 or whatever USB image and be able to beam that DIRECTLY to a USB stick with a dd command.
Or am a missing something here? Does this exist?It should by no means be mariginal, considering how important USB stick in specific and flash memory in general have become.
i have custom programs written in Basis pro5. Standard output to a pdf virtual printer works fine. Using pdftk to overlay on to a form is hit or miss....

View 2 Replies View RelatedI've been able to kludge a kill script which finds the correct pid for the kdeserver (or gnome server) after my system comes up in run level 5 so I can drop back to run level 3 mode. Lots of experimentation showed me that using telinit 3 and telinit 5 would occasionally leave the video memory in a mess and I would have the black screen of death.
I set the security parameter setting to autologin for me since I am the only user of my machine, but I still have to kludge the default setting under sysconfig (the DEFAULT_WM) under Window Manager to pick a certain window manager, so it takes time to manually switch the desktop.
Right now I can leave the gui and drop back to cli, but painful experimenting showed me that killing the X server is a no no. Right now I kill the kde server, which sends the SIGTERM to the X windows manager, which then figures out that it has to shut down.
Questions: Is there a better way of doing this? Apparently openSUSE figures that we have multiple users logging into the gui desktop, so the gui is always kept running and a login window with the desktop manager option forces the user to login in. With autologin, this never happens, but no choice of desktop is possible on the fly.
Can some type of script be set up to painlessly enable this to happen? And what is the best way of bringing either the Gnome or KDE desktop manager down gracefully? I do get lots of error messages as the system attempts to recover and X shuts down. It appears that apparently the single user with autologin is left out in the cold.

I've searched for answers in google, but get not i wanted. I wanted to prepare bootable iso from usb under Ubuntu. Fine, there's UNetBootin, dd if= of= command etc. But I am concerned and the specific type of iso images booting - AntiVirus rescue cd's.
Using UNetBootin i could only prepare thumb drive to boot Dr. Web Rescue CD, but neither Kaspersky Rescue Disk nor F-Secure Rescue CD couldn't be preapred well (NOTE that my BIOS can boot livecd from usb drive!). Using dd if= of= command also didn't worked, cause prepared thumb couldn't boot - get errors: "Missing operating system" or "Could not find kernel image: linux". Is it that i must install grub/lilo or syslinux on thumb, then edit .cfg file and then copy image, or what? I'm concerned only on AV Rescue Disk's, like: Kaspersky, F-Secure, GData Boot CD, BitDefender Rescue Disk etc. I've booted (and it worked) Symantec boot cd but it's based on WinPE and i had prepared thumb under Windows 7, so it's a completely different story.
I have Bootable USB Drive Assistant in my Ubuntu 9.04 but when i try to choose some of those cd's, i get error that "It isn't installable CD image, so application can't use it" or something like that. What application do i have to use then?
