Btrfs Arch-based rescue images

From linux-btrfs mailing list today :
http://comments.gmane.org/gmane.comp.fi … btrfs/3150
Hello everyone,
As Linus discovered, the new btrfs disk format in 2.6.31-git can be
problematic if your FS gets forward rolled to the new format and you end
up bisecting back to the old code.
It would also be nice to have a way to run btrfsck on a root filesystem
and do other assorted tasks. So, I'm making live boot usb images for
both x86 and x86-64.
They should have enough to get your filesystems mounted and they also
include git, gcc, make and enough to compile the kernel. These are
based on the Arch 2.6.30 distro with just the btrfs newformat code
added.
I've got the 32 bit image uploaded, and I'll queue up 64 bit overnight.
If anyone is feeling brave, just dd the image onto a usb stick and
rescue boot away.
They work on both of my test boxes, but a little extra testing would be
nice.

An arch based bootdisk that's only 30MB? I've got a way to go!
It says "Many utils are supplied by busybox" so I'd call it loosely based on Arch.

Arch-based medical distro

I started a simple project to build an arch-based distro for medical professionals
The base install is ready and my own-developed simple medical apps are in development to be included...
I was searching for more apps to include (medical image viewer, electronic medical records) and I found a lot of options, and have no idea what to include and where to start.. I never used any of them, (still a medical student), and I was wondering anyone could help in bringing birth to this distro?
Suggesting apps, or maybe helping in building and packaging apps not available in the official repo or the AUR? or even only testing?
Any interest?!

No worries - far better to be occasionally over enthusiastic, then never enthusiastic enough. There simply may be more productive ways to channel that enthusiasm: more productive both for you, your would-be users, and the rest of the arch community.
First, let me highlight the real problem with spin-off distros. You certainly could put together an installation iso with all the right stuff for a medical professional to put an arch-based system on their computer and start using it. But are you going to commit to maintaining it and doing all the hard work that really comes with maintaining a distrobution? If not, the best case scenario is that your distro would be a passing fad, and you'd get (probably less than) your 15 minutes of micro-fame. The more realistic scenario is that your distro would be just a fart in the wind - and as a result, so too would be your enthusiasm for contributing in other ways.
In contrast to all this, there are very productive ways to channel any such enthusiasm. A majority (if not all) of the great things about archlinux have come from one person scratching their own personal itch, then sharing the products with the community. This way they are giving back to the community - but it is not purely selfless: they are appreciated by the community. How small would be your target audience for the new distro? You'd tell a few collegues, and maybe one or two of them would share it with a few of theirs ... pretty small. But if you see software that could be useful to medical professionals that is lacking in archlinux and instead you make/improve AUR packages, or even set up an unofficial repo with the precompiled binaries, then any medical professional who searches the AUR can find your products.
Further benefits of this approach are that now your contribution will likely last much longer. There will be more users to benefit from it, and more to appreciate your contribution. And when you inevitably get too busy to maintain a few of the AUR packages, or the repo, there will be a much larger pool of potential volunteers to take over - thus preserving the 'legacy' of your contribution.
I suppose this all lends itself well to a parable of sowing seeds on different types of ground. Suffice it to say that being a successful farmer may have more in common with being a successful archer than one would first suspect.
And in contrast to my initial answer of "No", I would be happy to help you get PKGBUILDs working for all the tools you would like to make available in the AUR or in a custom repo. I also suspect many others here would be much more welcoming to this as well.

It sounds like you destroyed your boot partition and the recovery partition. Depending on it's age, your MacBook Air might be able to do a net boot. Plug and ethernet connection into it and attempt to boot. If it has the right firmware, it will find a net boot configuration on the net and boot that. Then it will give you a Recovery Partition like display and allow you to reinstall the OS X version that came with it.... assuming that it was Lion or ML. If your computer came with Snow Leopard, then even the net boot won't work.
At that point you need a bootable USB Key, or an external DVD drive AND a Snow Leopard installation DVD.
An Apple Store, if there is one nearby, MAY be able to get you going again. However, whatever is on the SSD now will be toast too.

[arch-based] TP-Link TL-WN822N losses

Hi. I need your help adjusting something wrong with my Arch-based distro and USB WiFi adapter: the last one is a TP-Link TL-WN822N.
The issue is this one: it often happens that automatically network disconnects from the home's WiFi network, not only when the computer is locked, but even if I'm surfing the internet or just using it.
Maybe this will help someone understanding something more specifically:
$ lsusb | grep TL-WN822N
Bus 001 Device 005: ID 0cf3:7015 Atheros Communications, Inc. TP-Link TL-WN821N v3 / TL-WN822N v2 802.11n [Atheros AR7010+AR9287]
If you need some other tests, I obviously will do it.

Here's a list of Arch-related distros. There are probably more floating around somewhere.

Making arch-based distro

Hello.
I started to make Arch-based distro. I have fully installed Arch + Openbox.
I have a couple of questions:
- How can I make an ISO from installed system I have?
- I haven't installed drivers for my graphics because if I respin it into a new system, users with nvidia graphics, for e.g. will involve with problems then. How can I avoid that, i mean, is there a script that will recognize graphics and download drivers for it?
That's all for now. Arch with Openbox and some setup rox.

Probably fully depends on the quality of AIF. The current method is very KISS and easy.

Bodhi Linux Arch-based build, need dev(s) and supporting team members

Hello forum,
First, apologies if I have posted this topic in the wrong thread. I am writing to inquire as to whether or not there are any other Arch users and/or developers that would be interested in assisting Jeff Hoogland with his new distro, Bodhi Linux, and working on an Arch-based build. Bodhi Linux is a Ubuntu-based distribution that uses Enlightenment as the desktop environment and is focused on promoting the light weight, beauty, and speed of Enlightenment while remaining minimalist. Jeff has plans to release a Fedora-based version of Bodhi in the future, as well as an Arch-based build, but he would need some help, specifically with the OS disc itself. He can work on the Enlightenment side of things. Is there anyone interested in working on such a project? If you haven't heard of Bodhi Linux already, please visit http://bodhilinux.com/

Greg_S. wrote:ANOKNUSA, you think it's wasted energy? "Throw-away distro" is it?
Sorry if this seems unduly harsh. I wasn't trying to troll, but merely reiterating what others here have said. The Bodhi Linux developers are certainly within their right to direct their efforts in any way they wish. However, they have two serious conceptual flaws they need to consider and overcome:
1) Are the devs planning on releasing both x86 and AMD64 versions of Bodhi? Even if not, this still means that once the project gets going, they'll need to build the entire E17 compilation three times a week; if so, they'll need to do so six times a week. This is very tedious and time-consuming for a group of people working in their spare time, with no financial backing or chance for compensation. Naturally, it leaves very little time to maintain the rest of the repos, discuss/research/pursue further development, track bug reports, etc. The latter is worth noting, since
2) The devs will need to keep track of bugs and development roadmaps for three different distros, each with their own kernel patches, boot/init protocols, etc. They'll need to build separate packages and "tune" separate repos for each spin, provide a forum(s) able to handle questions regarding each spin, with devs and moderators specializing in each spin.
This is an awful lot of work to simply "showcase E17 and give it the 'love' it deserves." The Enlightenment devs are the ones providing the weekly snapshots on SVN; the Bodhi devs just package them. If promotion of Enlightenment DR17 is the ultimate goal, it could be better accomplished by establishing and promoting a PPA for Ubuntu, a PKGBUILD or PUR for Arch, and a (name of unofficial repo here) for Fedora. This would make an up-to-date version of E17 readily available, and require only promotion and packaging on the part of the maintainers. Bug reports could be sent directly to the Enlightenment folks with no need for an intermediary, as well as to the appropriate distro, rather than sending them to Bodhi which must then check to see if the problem is one extant in the base distro concerned before applying efforts to fix the problem. Just think: you get a bug report and begin to reseach it, only to find out it's a problem you inherited from Ubuntu which in turn inherited it From Debian [unstable]. Where does that leave you? If you do manage to fix the problem, then the only decent thing to do would be to share whatever patch/code changes you made with the folks upstream anyway.
I ain't trying to be a killjoy here, and I'm definitely not trying to discourage the commitment and spirit of contribution the Bodhi folks obviously have; just the opposite. Besides, it does look like you found at least one Archer willing to help you guys, so whatever ends up happening, I wish you all good luck with it.

New FaunOS Live Arch-Based DVD/USB Distro Now Available

Hello fellow archers,
We have just released the latest version of FaunOS. Since this version of FaunOS is the answer to the most important question in the universe, we have named it "fortytwo."
FaunOS-fortytwo contains many improvements over previous releases and more packages (575 total). Improvements, in no particular order, include:
- Improved wireless support, both wlassistant and knetworkmanager are now included.
- Improved automatic X configuration with 3D acceleration.
- Better boot splash support. We have moved to fbsplash which seems to work pretty consistently and has lead to a faster boot time.
- A new boot option for quickly booting into a console-based system with no X windows.
- A new boot option for machines that hang when booting from DVDs using piix modules.
- Ability to save FaunOS session back to a multi-session DVD-+R or DVD-+RW.
- Permanent Arch Linux Installer using archin.
- Permanent FaunOS Installer for creating additional FaunOS USB drives from within FaunOS and for performing a "frugal" install to hard drive. Frugal install (not to be confused with Frugal Linux) installs the compressed FaunOS files to a hard drive permanently leading to an "unbreakable desktop" meaning the end user can totally ruin everything at runtime. To revert back to the starting point all the user has to do is reboot the machine and everything goes back to normal since all changes happen in ram, unless the FaunOS session is saved at boot time.
- FaunOS is probably the only live distro that can perform two kinds of installations.
- New added packages include: wlassitant, madwifi, firmware packages for ipw2100 and ipw2200, ndiswrapper, lynx for text-based web browsing, and kmobiletools accessing phone books and other information on mobile phones.
- All packages have been upgraded to the latest from the Arch repos as of today, 8/27/2007.
- And, most importantly, a new logo.
We have also decided to stay away from the evil 2.6.22 kernel which seems to have created more bugs and headaches than introducing new features, no flame war intended. The latest 2.6.21-faunos kernel is based on the stock arch kernel with the addition of the fbsplash patch from genpatches.
There are those people that may think FaunOS is bloated, but we like to think that it is a muscular and strong live Linux distribution, thanks to Arch. Of course keeping with Arch's KISS principal, we have tried to make FaunOS simple and easy enough for anyone to use.
You can get the latest version at:
http://www.faunos.com/downloads/faunos-fortytwo
A new wiki has been created at http://wiki.faunos.com. Feel free to contribute and change the wiki as you wish.
Our support and discussion forums can still be found at http://forum.faunos.com
We can definitely use some mirrors for our downloads. We will also be creating a torrent shortly and can use some seeders. Please let us know either here or in the FaunOS forums if you can help in any way.
We'll see ya at the FaunOS forums!
So long and thanks for all the fish,
Raymano

We have simply used larch but with some additions and changes:
- FaunOS uses a slightly modified version of larch with the added ability to build a live system from a preinstalled partition on the harddrive.
- Added fbsplash capabilities to the initial initrd images and kernel.
- Applications on FaunOS are preconfigured and integrated to work out of the box.
- Some kernel specific modules/packages have been compiled for the FaunOS kernel, e.g. ndiswrapper.
- All services are pre-configured to execute out of the box.
- All available codecs are included.
- 3D desktop using beryl is preconfigured to run on intel based graphics cards and some ATI cards with a click of a button.
- Network management is simplified with use of knetworkmanager and wlassistant.
- Storage are is included on the FaunOS device to share files with other platforms.
- R/W access Windows parititions by clicking on an icon in KDE.
- Common grub booting on USB and DVD. With multiple boot options for graphical and non-graphical system.
- FaunOS's own mkxorgconf utility was added (using hwd) for better automatic configuration of graphics cards. This includes setting up AIGLX.
- Easily performs frugal install of the live FaunOS system to hard drive, including saved overlays. This was not part of the original larch scripts.
- Use of sudo to allow the user to perform certain system wide configuration tasks.
- Integrated flash java and mplayer plugins for Firefox.
- Ability to put a computer running FaunOS into sleep (suspend-to-ram), remove the FaunOS media, boot and work on other computers with the FaunOS device, return to the original computer, insert the FaunOS device, turn on the computer and continue working where you left off. This in not possible with latest Arch Linux because of the kernel.
- And we believe, most importantly, you can hand a FaunOS DVD to a user with no knowledge of Linux and say go try this out.

Arch based distro - same repository?

hey,
i got a question.
let's say i'm making a new ,archlinux based distro. must i use own repositorys then or can i just use archs repositories? i won't really make a new distro (no time for that) but i always asked myself this question.
pure curiosity.

Ιf it's rolling, I guess there is no problem, but you need to make it clear (on the distro site for example) that the most of work done is thanks to the Archlinux devs, if you are gonna use the official repos.
Chakra-project for example is Arch+KDEmod, thus it currently* uses the official repos.
*they are gonna make their distro, afaik, non-rolling.

Arch Linux Xen Image

Has anyone tries making a Xen image of Arch (as a guest OS)? I want to do it so I can run arch on a xen cluster I have access to, but i'm not sure where to start O.o

I run Arch on a Linode, not by using their premade image but rather starting from scratch myself.
Linode provide kernels outside the Xen guests, which made the whole thing quite easy.
Here's a rough summary of how I managed it:
1) Install a minimal base Arch system in a virtual machine. I used the FTP iso and Virtualbox.
As Linode provides kernels, I left out the following packages:
kernel26, kernel26-firmware, kernel26-headers, grub and all initcpio and klibc packages.
2) chroot into the new system. Modify fstab to match the Xen disk layout. Configure the network
interfaces and anything essential to boot.
3) Exit the chroot, cd into the directory where it resides and tar the entire filesystem up:
tar -zcpvf filesystem.tar.gz ./
4) Boot the Xen guest with a livecd of some sorts. Linode provide Finnix.
5) Mount the Xen disks and copy the filesystem tar to the Xen machine.
6) Untar the OS:
tar zxpvf filesystem.tar.gz ./
7) Restart your Xen guest into the Arch filesystem and configure away.
I know it's not very detailed, but I did this quite a while back and have just recalled it
all from memory ^u^
Good luck!

Dark arch shadow on images

Hi! I'm trying to trouble shoot a problem I'm having with my camera. There is a dark shadow-looking arch that is showing up on almost all of my images. I'm having this problem with multiple lenses so I know it's a camera issue and not a lens one. Has anyone seen this before? Any ideas as to what is causing this? Thanks for your help!

I'm wonder if there isn't a "hair" on your sensor (technically there are two filters in front of the sensor so it's not really on the "sensor" but on the glass filter in front of the sensor.)
To test this,
1) please set your camera to Av mode.
2) Find a plain image with little to no contrast (the more plain, the better). A plain white wall or white ceiling works extremely well.
3) Set the camera to it's MINIMUM f-stop (run the main dial (top near the shutter button) the the lowest f-stop possible and take an exposure. If your lens goes down to f/3.5 use f/3.5. For this test if you are shooting a plain scene such as a white wall it actually does not matter if your subject is in focus or if the shutter speed is too slow to hand-hold the camera.... that's because we're not trying to study the scene but rather than shadow cast onto the sensor).
4) Set the camera to it's MAXIMUM f-stop this will likely be f/22 but some lenses do f/32 -- again, but adjusting the main-dial (near shutter button) to the highest value. The high f-stop will require a much longer exposure time. Take an exposure.
Unload the images and look at them on your computer.
If the shadow is caused by something resting on the "sensor" (really the filter in front of the sensor) then you'll have a weak but broad shadow at low f-stops and sometimes it may be very hard to even notice that it's there. But the image taken at a high f-stop will have a much more distinct shadow.
This can explain why you only see the problem in "some" images.
If it is on the "sensor" -- don't panic. It's very easy to clean if you know how.

Error trying to mount the DVD to a network based ISO image in Windows 2008 Hyper-V RC0

Greetings,
When I try to configre the guest OS settings to mount the CD/DVD drive to an ISO image I have setting on a file share, I consistently get an error. The only time I have been able to mount an ISO since upgrading to RC0 (I don't remember if I tested this in the BETA) is when the ISO is locally on the Windows 2008 Hyper-V server.
To be specific, I get the following error:
Virtual Machine Connection (title of the window)
Inserting the disk failed.
Failed to add device 'Microsoft Virtual CD/DVD disk'.
User account does not have sufficient privelage to open attachment '\\remoteserver\share\ISONAME.ISO'.
Error: 'General access denied error'
'NEWGUESTOSNAME' failed to add device 'Microsoft Virtual CD/DVD Disk'. (VMID 26C8B66F-5D3F-47F9-9D80-474D0F778522)
'NEWGUESTOSNAME': User Account does not have sufficient privelage to open attachement '\\remoteserver\share\ISONAME.ISO'.
Error: 'General access denied error' (0x80070005). (VMID 26C8B66F-5D3F-47F9-9D80-474D0F778522)
I am not sure what credentials it is using. It looks almost like it is using the new computer name as credentials or something like that. The account I am logged in as at the time is a Domain Admin and has access to every server and every share. I can browse to the ISO just fine through the Hyper-V Insert Disk function, it just won't take.
I have checked the Hyper-V server settings and the Guest OS settings and can't find where to specifcy what account to use to connect to remote ISOs. Anyone have any clue on what I am doing wrong?

Thanks for the various replies.
Understood it is an issue with the Hyper-V server computer account getting the files, and not the actual guest OS. At this point I think I will just copy some ISO's to the server. I did note the last time I used a "local" ISO that I had to manually type out the local path to the files on the server, as when I tried to browse to the local server drives through the console I got an error about connecting to the local server (which wasn't really local) through the network drives. I don't remember the exact error, but I know I couldn't get it to point to the ISO on the D:\ drive through the browse feature, but rather I just typed out the path and it was fine. That too seems like a bit of a buy/annoyance as I should be able to browse files local to the Hyper-V server, and not have to type out the path.
I guess I would ask MSFT to consider changing the behavior of the console just a little before RTM if it is being run remotely against the Hyper-V server, versus locally on it, if the permissions being used to get to the remote files are going to be different depending. I.E. It is not intuitive that the same exact action in the same exact console would behave any differently when the console is run on the Hyper-V server versus remotely against the Hyper-V server. I.E. Add in a pop-up when remotely connected to the Hyper-V server to let the user know that some permissions may not proxy through (or whatever verbiage you want to use).
This will pop-up more and more as people like me try to deploy Hyper-V on Core servers, and they used Hyper-V on a normal Windows 2008 server previously.
Thanks!

How to display non-URL-based thumbnail images in JTable

I'm trying to display thumbnail images as a tooltip popup for certain cells in a JTable. The thumbnail images are java image objects that have been retrieved dynamically as the result of a separate process--there is no associated URL. For this reason, I can't use the setToolTipText() method of the JTable.
My attempts to JTable's createToolTip() method also failed as it seems the ToolTipManager never calls this method for a JTable.
As a workaround, I've added a MouseMotionListener to the JTable that detects when the mouse is over the desired table cells. However, I'm not sure how to display the popup over the JTable. The only component that I can get to display over the JTable is a JPopupMenu, but I don't want to display a menu--just the image. Can anyone suggest a way to display a small popup image over the table?
Thanks.

Thank You Rodney. This explains why my createToolTip() method wasn't being called, but unfortunately I'm no closer to my goal of displaying a true custom tooltip using a non-URL image rather than a text string. If I make a call to setToolTipText(), at any point, the text argument becomes the tooltip and everything I have tried in createToolTip() has no effect. However, as you pointed out, if I don't call setToolTipText(), the table is not registered with the tooltip manager and createToolTip() is never even called.
To help clarify, I have attached an SSCCE below. Please note that I use a URL image only for testing. In my actual application, the images are available only as Java objects--there are no URLs.

Image copy to folder with name based on image creation date

Hi all,
I am new to Mac OS X and automator so I would like to know the following,
Is it possible to have an automated action that triggers when I attach my camera to USB, and who copies all images to a folder which is named according to the date when the image was created?
Example:
I attach my camera and it shows up as disk image named "NIKON D70" and the images are contained in subfolders "DCIM/100NCD70" (or actually in DCIM/*). I then want all images in these folders copied to my home directory in a subdirectory called something like "Pictures/D70/2007/20070605" where the year folder name and the date folder name should be according to current image creation date (which of course can be different for each image).
I have created a simple automation script that copies images from my camera to a folder named according to current date, but that's not good enough.
Anybody having any hints or ideas of how I can accomplish this?
Regards
