Compare directories on separate workstations

I am having a terrible time trying to come up with a way to compare two directories stored on separate computers. Any tips would be greatly appreciated.
A little background: I am writing an rmi application that provides file sharing an backups of music, videos pictures, etc. The problem is I want to compare a directory on the client machine against a directory on the server so that I can display what is missing in a JTree. I created a class that takes two files as arguments and creates tree nodes from them that are color coordinated. This works great as long as I run the client and server on the same machine. I didn't realize that I couldn't pass the directory stored on the client machine as a "File" to the server and have all the subdirectories intact.
I assume I will have to come up with some way of representing the directory and all is subdirectories in some way that I can pass to the server. However I am at a loss at this point. Maybe an XML representation of the directory? Any suggestions would be appreciated.
Thanks in advance,
Dan

Hi fromhereon,
If you're using RMI, you can manage the client sending a simple list of the files(an array of String) present in his directory and you compare its content with the directory content on the server side. IMO, there's no need to jam the application with XML files which need to be build, parsed or validated.

I tried to search about the built-in oracle procedure that compares (Directories, initialization parameters, roles, profiles, tablespaces, users, redo logs) between two different databases but I did find it ..
So if any on knows it please forward it to me as soon as possible.
Thanks all.

Wrong forum. The Database General might be more apropriate. Also you should read this: http://www.catb.org/esr/faqs/smart-questions.html very carefully. If you would have used google before dumping your question here in the wrong forum you might have gotten solutions as well:

Dynamic Link on Separate workstations cs6?

I am an editor working through a server with a motion graphics artist. We are trying to use dynamic link so that when the AfterEffects artist makes a change to the file, it's automatically changed in my edit. However, when working on two separate stations it seems that in order to update the changes I have to "edit original" on my premiere project, which then opens my AfterEffects and the project. Is there a way around this so I can just click something to "update" the aftereffects comp instead of opening everything up, then having to close it again?

As Harm says, you are on a road that leads to problems
PPro does not like to directly edit networked files... the most you can do is keep your "original" files on a server, copy to a workstation to edit, and copy back to the server when done

Does GoldenGate director need a separate license?

I also checked the GoldenGate product page on www.oracle.com, sounds like the GoldenGate Director has gone, it is called GoldenGate management pack. Please also help to confirm. Thanks

Hi,
GoldenGate Director is now part of Oracle GoldenGate Management pack.
Oracle GoldenGate Director requires separate license and complete licensing information of all the Oracle GoldenGate products is available at below link.

How is Director different then Flash, and which is better for
game development, web based games or otherwise?
What is latest or best version of Director avaialble today?

Hi Ripps.
The question of Director vs Flash has been asked many times.
I have a FAQ page relating to this with links to articles at:
http://www.fbe.unsw.edu.au/learning/director/resources/FAQ/web.asp#5
Here's another link to an article called
The Best Kept Secret in Town - Application development with
Macromedia Director
http://webddj.sys-con.com/read/45623.htm
It also compares Director to Flash from an application
development point of view.
The Director Podcast had an episode on Director vs Flash. It
can be downloaded from:
http://www.magicgate.com/podcast/director/shownotes/director_podcast_ep20_06_13_06.html
The short answer is that Director is superior to Flash in
many ways including
* supports real-time 3D
* has a greater range of digital media support
* supports plugins (Xtras) to allow the software to be
extended
* Director can access operating system commands
Flash is better than Director in some areas. So, if you want
to create a game or some other application, your
choice of tool will depend on what exactly you want it to do.
To your other question, the current version of Director is MX
2004. This is version 10. There's a 10.1 and 10.1.1
update that are free to download. Adobe have announced that
Director 11 will be released by the end of this year.

Chmod Multiple Directories via Terminal Script or Applescript

Hey everyone!
Im managing multiple labs and unfortunately need to change some directories on my workstations in order for my network users to access Applications with no errors. So i'm looking to create an Applescript or terminal script (not to fluent with terminal scripts yet) that will chmod 777 all of the directories I need to open. Can anyone help?
Does anyone how to prep a Applescript where I can just add in the directories that I need to modify?

I don't reccomend chowning any folder on a lab machine 777.
I manage over 700 macs in a university environment and almost no software requires that frivolous of a permissions scheme. most temp files will be written to the user's home directory, at most you want to set applications 0775, or 0755
but if you want to change the perms on a specific list of programs / folders then you can put all the names of each folder in a text file and loop through that
-------------this is your script------------------
#!/bin/bash
file="your text file"
for i in $( cat $file ); do
chown -R 0775 $i
done

Poor Rendered Video Quality PE7

Hi All,
I've been running the trial of PE7 for a few weeks comparing against my existing copy of Pinnacle 10 and trial of Power Director. I love the interface and edit abilities, however when I generate DVD files and view them the result from PE7 is of a much lower quality than from Pinnacle or Power Director.
I'm using the default quality settings in each of the programs and viewing all with the same DVD viewing software (AVS Player). The originating AVI that was edited was captured using Pinnacle, but I imported it into PE7 and rendered a PE7 DV AVI for editing to make sure I was working with PE defaults. The picture seems to be more grainy and less vibrant in color with PE7. Of course having the big black "PE7 Trial" directly across the middle of the screen doesn't help with comparison (what possessed them to put the watermark directly across the focal point of the viewfinder?), but I'm pretty certain the PE7 files are not as good.
Is there some setting that I'm missing that would make the video from PE7 that much worse than the other two products? I can't believe that the Adobe product would be that much worse without someting I'm doing wrong or missing.
Thanks in advance for any suggestions!

Dale,
The test of each program would be to author a DVD (use RW, so you don't spend a bunch of $ on test DVD's) and then watch that through a DVD software player on the computer, or on a set-top player to TV.
As for the display in the programs, there are a couple of things to look at. In PE, if your DV AVI Clip shows a green line, above the Timeline, it does not require Rendering. If it's red, just hit Enter, to Render it. If you Rt-click on the Display Monitor, you can choose Fit, or one of several resolutions - choose 100% and see if your display improves. Fit is basically a "draft preview," sized to fill the Display Monitor, where 100% should show the actual detail.
It's been a long time, and several versions ago, since I last used Pinnacle, but I was less than impressed by its "monitor" back then. However, I am going both from memory and also this was on a previous laptop. Though it also had a 17" monitor, the rez was way down (totally different GPU), than what I am now using.
I have Power Director on my workstation (dual 21" CRT Hitachi 915's), and I see no difference between it's display, and that in P-Pro2, when I switch it to 100%. They both look the same to me. Do not have PE on the workstation, and do not have Power Director on the laptop, so I cannot compare those in an A-B situation.
Going back a couple of versions of P-Pro, Adobe went from DirectShow display to a common display engine for all of their programs. It has been my experience, when setup to 100%, that their displays are equal to, or better than, any program using DirectShow. This is for footage that does not need to be Rendered, or that has been Rendered, and is for 100%, and not Fit. I do not know if Pinnacel and Cyberlink still use DirectShow.
One last item to consider is the display settings on your monitor. Because Adobe does not use DirectShow any more, you could have differences there. I'd spend just a bit of time with the settings on your monitor, both in the Windows' Display, and in your GPU's utilities, to see if you can "calibrate" your monitor for best viewing of the Adobe display engine. In my nVidia Quadro 4500FX control panel, I have one setting for "Print Work," and one for "Video," and my needs fluctuate between the two. I also use Adobe Photoshop's Adobe Gamma utility to set things up for my print work. It is no longer included in the latest CS3-CS4 Photoshop.

A formal request.

I would like to formally address an issue regarding Adobe's
support of the Linux platform.
As a professional, I have been using Linux for years. I
started my technical consulting and support business running Linux
primarily on my desktops and servers, using productivity
applications such as OpenOffice, Firefox, Thunderbird, GNUCash, and
others to get work done. I have gotten along great with it, and am
proud to say that to this day, I am an avid Linux user and
supporter. I haven't been able to find one reason to switch to
another platform with my business yet.
Recently I was contracted by an elementary school district in
Northern California to convert all of their student computer labs
from Windows 2000 workstations to Linux/LTSP thin clients. This is
a common situation for educational institutions these days, as
software licensing is becoming a rather large headache for those
with limited IT budgets, not to mention the ease of administration
with thin client networks compared to the traditional
workstation/server network model.
I am on school 2/7, setting up servers and reconfiguring
aging clients to boot from the network...myself and the district's
IT staff could not be happier with the way things are working out -
with one exception.
Unfortunately, the time I have primarily used setting up
Linux LTSP computer labs have been dealing with getting Firefox
Flash and Shockwave players working correctly. Here is our standard
lab setup for the 7 schools to be converted:
- HP Proliant ML370 G5 server (dual quad-core Intel Xeon
64-bit processors, 8GB RAM)
- Neoware e100 thin clients (32-bit, 128mb RAM)
- Ubuntu Linux (64-bit server edition 7.04)
Our first issue was Flash. Although Flash 9 has been released
for Linux (although much later than it was for Windows/Mac), the
only architecture it supports is i386 (32-bit). This required a
*completely* separate install of Firefox (the 32-bit version),
alongside the standard 64-bit version installed with Ubuntu 64-bit.
This took a lot of time (and money for the schools) to accomplish.
I found, after much research and headache, a script which attempts
to automate the technical nightmare that is installing 32-bit
browsers/plugins in a 64-bit environment. It is here:
http://ubuntuforums.org/showthread.php?t=202537
. This, I thought, was the end of a big hurdle to get the schools
migrated to Linux.
Unfortunately, it wasn't. The 32-bit version of Firefox,
being a browser with a different CPU architecture, does not
correctly talk to default Ubuntu installed printer libraries. I
doubt many who develop for Ubuntu could have caught this, since it
is the community that plugs these holes, specifically for these
types of situations.
So, even if the students could now use Flash-enabled
websites, they could now not print anything from their browsers.
The next (major) roadblock is Shockwave. Now, it seems that
Adobe is completely ignoring Linux support for Shockwave all
together. There are no indications of any Linux support for the
Shockwave player/Firefox browser plugin for Linux. This is a MAJOR
issue, as the students' curriculum use Shockwave-enabled websites
to learn. Basically, if we can't get Shockwave running on our Linux
network, the students will be missing out on a major educational
portal, which means the learning process that goes on in school is
crippled. This would all be due to the lack of support Adobe is
giving the Linux platform.
On top of these issues, the fact that Adobe is only releasing
its players in 32-bit architectures is extremely hard to believe.
Even if Shockwave is ported to Linux, the possibilitiy of it (or
Flash) being compiled for 64-bit architectures is but a far cry in
the woods for a Starbucks double espresso. I simply do not see how
Adobe is holding back on putting their resources to unifying their
Internet-standard web products such as Flash and Shockwave. In my
(very humble) opinion, Adobe is doing a great disservice to the
Internet community as a whole, and is being very irresponsible as a
major software company that so many people rely on for their
Internet experience.
Please give more of your resources to the development of
unifying your web-based players such as Flash and Shockwave. It was
said in an article here:
http://www.linux.com/feature/32077
, that Adobe would make a Shockwave player for Linux if they
received a "few thousand requests".
Well, take a look at this online petition to get Shockwave on
Linux:
http://www.petitiononline.com/linuxswp/petition.html
. If you click on "View Current Signatures", you will find as of
2007/09/12, 10:29am PDT, 26,275 signatures have been added. A 'few
more' than a 'few thousand', don't you think?
I eagerly await a response from any Adobe representative on
this issue. I am determined to get what so many are asking for, and
I am willing to spend even more of my time to show Adobe what they
need to see from the people they are working for.
Thank you for your time.
Sincerely,
Jordan Erickson

Thank you Adobe for your ignorance in questions of amd64
flash. There is so much advertising is passing by and not stopping
on my computer that i probably saved myself a fortune on traffic. I
am so much thankful to you for not releasing BIG products like
Photoshop to Linux platform which gave me a good opportunity to
check out open source alternatives. I am not a designer, but rather
all around computer enthusiast, so my Photoshop skills were still
very well implemented in Gimp, even though i am not doing design
for life. However I am not Adobe hater. I still use Adobe Acrobat,
even though i know some very good alternative products, question of
price is irrelevant, since all of them are free.

My iMac G5's Hard Drive Has Most Likely Failed

So my hard drive has been having problems since November 2005, but the computer has been barely holding out, until now. The computers just dead. I got this message from
It happened at the most random time. Yesterday morning, I turned on my computer and opened Safari. Everything went just fine, and about 3/4 way through loading the apple startpage, the entire computer froze up.
I tried disk utility but it froze while verifying and repairing disk permissions (about 1/8 started and it froze) and when I did verify disk, it came up with a popup window stating:
Error: The underlying task reported failure on exit
And then in the Disk Utility information window where it says the status that its at (Checking....) it said this:
Checking HFS Plus Volume
Checking Extents Overflow File
Checking Catalog File
Invalid Sibling Link
Volume Check Failed
The underlying task reported failure on exit.
1 HFS volume checked
1 volume could not be repaired because of an error
Then I ran fsck in single-user mode, and i got this:
#fsck -fy
disk0s3: I/O timeout
(4, 7808)
I'm not sure what the coordinates mean. I'm thinking they might be the coordinates to a bad sector that may be screwing EVERYTHING up because the computer failed to recognize the bad sector, and close it off of any further use.
After that I ran diskutility in single-user mode thinking maybe the GUI version was corrupted... but I let the diskutil verifyPermissions /dev/disk0s3 run for an hour and nothing showed up on the screen so i just decided to stop, shut down, and go to bed.
So now i've figured, my iMac has given me enough trouble as it is. ive had so many problems with it... ever since november 2005 (5 months into owning it) it has had the following hard drive error code show up in extended test for the Apple Hardware Test ever since... and about 1 hour ago, i retested it, and sure enough this came up:
**ERROR*CODE***ERROR*CODE**
2STF/8/3: S-ATA Bus O-Master
**ERROR*CODE***ERROR*CODE**
I'm really not happy with mac right now. I think their 1 year warranty is useless and they pretty much leave you screwed if you dont buy their applecare protection plan.
I have a windows 98 (upgraded from 95) that i bought way back in 1997, and its still functional... with the same hard drive... same everything... and it works just fine... except for the memory is small because back then 128 GB was the biggest it got) :P
so a 5 GB hard drive going on its 10th working years, and this 150 GB hard drive failed after 14 months... all i've gotta say is: Apple, thats pretty pathetic... especially after you mock PC in their commercials for "breaking down". Ive actually had less problems with all of my 3 PCs combined then I've had with this **** iMac.
So now heres what i'm trying to figure out. i'm wondering, what kind of hard drive i shuold buy to replace it... i tried the DIY hardware replacement ordering page but it says that the apple website couldnt find it (http://www.apple.com/support/imac/g5/diy/).
I wasnt planning on buying from the apple DIY anyway, but I wanted to see if it would specify a type of hard drive. Where is the popular website to go to buy these things, and how expensive will it be for me to replace it with a hard drive about as big as my current one).
Or should I not throw my hard drive away yet, and invest hope in it somehow. I heard DiskWarrior could do the trick, but I dont want to have to spend $80 on a piece of software that might not even work out right. And all the free ones you have to download to your mac... but too bad for me, my mac wont even start up... (well it does but when it gets to the desktop, its pretty much unfunctional... just a moving mouse that wont do anything).
Is there some renouned website (as crucial.com is for memory) among these forums that you might suggest?
I'm open and desperate for any input i can get. The sooner the better
Thanks in advance

Hey look, its my friend Charlie from my Disk Permissions Error -36 post.
Here's our thread from last time. Alot of the stuff there still pertains: http://discussions.apple.com/thread.jspa?threadID=620422&tstart=0
It turns out the reformat I did only worked for a little while. Then last friday, my kernel was corrupted, and so i did "Erase All" but skipped the "Zero All Data" figuring that it wouldnt be necessary since I wasnt discarding my drive, so there wasnt anything to secure from anyone recovering private data. It worked for 4 days after that, and now I'm here again. With problems.
Do you remember getting disk I/O errors on disk0s3?
If you remember way back then, I had gotten this error when I did diskutil list in Terminal:
Aug 30 21:42:08 mark-imac-g5 kernel[0]: disk0s3: I/O error.
/dev/disk0
#: type name size identifier
0: Applepartitionscheme *149.1 GB disk0
1: Applepartitionmap 31.5 KB disk0s1
2: Apple_HFS Macintosh HD 148.9 GB disk0s3
I'm running DiskWarrior right now (borrowed it from a friend... didnt feel up to paying the $80 & have it potentially not work) and its stuck at this message:
Rebuilding Directory Data
[ |||||||||||Solid Progress Bar||||||||||| ]
Step 5: Locating Directory Data
[\\\\\\\Barbershop-like Progress Bar\\\\\\\]
Speed inhibited by disk malfunction (Skip) (Cancel)
Its been stuck there for about an hour, and I'm assuming its not going to work as you suggested it wouldn't
It's too late to do any good now, but if you ever run the
hardware test and get an error code, you should have Apple
look at it. If you were getting that error code 5 months
after the computer was new, a replacement drive would have
been covered under your warranty.
I wish I had actually done so. I was a mac-noob back then so I had no idea what anything was, and I was still getting used to the actual working-with-a-mac thing (ive been a Windows user for most of my life except for working/helping teachers with their macs at school... i was always the computer-person in school... it was pretty awesome :P)
I have to disagree with the other posters. I don't think >DiskWarrior is going to help you. Data Rescue II might help >you to get some files off your hard drive if you have files >on there that aren't backed up. But my experience was that >when I got the error in the hardware test, DiskWarrior >didn't work.
Right now I have everything backed up that I need, so it's not like i'm using DiskWarrior to get my data back. I just want a program to be able to tell the hard drive that these certain sectors that are acting up and causing the hard drive to fail are ruined and to not use them anymore. If its not just 1 sector, but the entire hard drive that is failed, I'm not even gonna bother salvaging it (even though i'm sure if it was completely failed there would be no way of getting it back that deep into failure).
I read at this website about someone else who had a similar problem to mine (http://www.desktoppublishingforum.com/bb/archive/index.php/t-901.htmldiskwarrior+speed+inhibited+by+diskmalfunction&hl=en&gl=us&ct=clnk&cd=2):
ElyseC - 07-14-2005, 11:52 PM
And now the latest reply from Marc the support tech:
There have been a handful who have seen success after four
or five days with the "speed inhibited by disk
malfunction" message. There have also been a few
up to a week. From there, admittedly, the state
of the drive has to be pretty damaged for DiskWarrior to
run so long, although the speed DiskWarrior can work is
also related to the speed of the processor, so four days
for a G3 is different than four days for a G5.
She later posted this:
,..for a variety of reasons I ended up letting DW chug away on my drive for a few days shy of an entire month.

Apparent kompare bug(s)

I apologise in advance for the length of this 1st-Arch-post-in-years. I value context more than brevity, I guess. Hopefully this is the longest post I'll throw at Arch for a long, long time.
I looked around (quite) a bit before filing this post. I've used Arch off-n-on since 0.4, know the Arch site, the basics about Arch, and most of the "gotcha's" farly well - but I'm no sysop, either.
I have a project I've been needing and meaning to work on for years (and which continues to compound itself while I don't); a huge set of backups on CD/DVD of all my data (my *life*, really) for well over a decade - letters, graphics, email, the first 40 pages of my book, you name it. Over the years this 'little' library has grown to over 10 GB compressed (30,000 files, *most* of them ARCHIVES). My guess is that 2-4 GB (compressed) of the data is important, some very much so.
My archive collection consists of many recursed archives themselves, and they're in about 8 or 10 different formats, to boot (even *.ice, LMAO). Many are further embedded several levels into the main archives (yes, I know that's a bad idea, but I didn't know that when I created them...). I BADLY need to unpack all this stuff, find and toss the duplicates, and truly organise (and efficiently backup) the remainder. This effort will obviously require a lot of automation (or else my heirs will either do it, or not).
I'd found a couple of useful tools in the Windows world years ago, but I don't buy software and the key piece of my suite was shareware that disabled itself after 30 days - not nearly enough time to plow through this boatload of bits.
A few months back I built a system with an Athlon XP 3500+ on an Asus A8N-E mobo w/512MB and 120 GB and 250 GB HD's. I'm hoping to go the RAID route soon - Linux software RAID, in fact. The 250 GB HD is running off an add-in PCI ATA card; both HD's have a UDMA channel all to themselves. The machine's got 4 extra fans, a nicely oversized 485W P/S, and the on-board sensors consistently show it running cool. I'm quite sure this isn't a H/W problem (I'm having no others; I built it myself...). This machine has been absolutely rock-solid in every other regard. I LOVE the system; now if I can simply use it for this one basically administrative project.
I finally have both the speed and the space required to tackle this now-monster project. When I "came home" to Arch a few months ago, I wanted to try several WMs/DMs; GNOME, KDE, E17, fluxbox and ratpoison (at least) are all loaded on my system, and I've booted most at least once. I'd assumed I'd have a LOT of options as to the tools to use.
I've been man-paging and googling and pacman -Q'ing (followed by more googling) for a couple of weeks through the course of my testing thus far, while trying various wrappers in various WMs. My concluson: Houston, we have a problem! <S>Maybe</S> Several.
In the past I've been partial to KDE (that's quickly changing), and it's what I started with this time around. As such, kompare seemed the obvious route to go, and had MOST (NOT all) of the functionality I needed (I also very much like it's GUI). Of course, kompare is simply a wrapper for diff (several diff variants, in fact, potentially). It's possible that diff is the problem. Hopefully further testing (and/or comments here) will make that determination more clearly.
Subsequent googling has revealed that the diff version shipped with Arch likely hasn't been completely functional at all levels in almost *5 YEARS* now. Diff's codefile timestamp is Sept. 3, *2002*! Version 2.8.1 (3.4 is current - just like *kompare*'s current version is 3.4). Additionally, directly below diff in that listing is diff3. Diff's codefile size is about 60K; diff3's is about 20K. *However*, they both have the same timestamp AND version # !!!
A *completely cosmetic* bug (http://bugs.kde.org/show_bug.cgi?id=138347) is fairly clearly the same bug as (https://bugs.launchpad.net/ubuntu/+source/kdesdk/+bug/45466 - 3-1/2 *YEARS* earlier!), and seemingly a trivial patch for a competent maintainer to create, at that. I've verified (w/o even trying) that this bug is resident in my system as we speak. Of course it is - the version of diff Arch is currently shipping was compiled almost a YEAR before the FIRST of the 2 bug reports above were filed! My Arch desktop O/S was installed less than a month ago using the 0.7.2 base ISO (kompare's timestamp is Jan. 20, 2007; version 3.4 - and it's a wrapper for a piece of code last compiled in 2002? What, the 2.0 kernel?). I've aggressively maintained my system current since my very recent install. See how well kompare/diff work on YOUR system...
Indeed, from the kompare bug page, it's hard to believe it's EVER been stable - or even used (see http://bugs.kde.org/simple_search.cgi?i … &offset=20 and just keep on clicking "View More Results" - or get yourself an energiser bunny to do it for you, maybe).
I copied the backups from CD's/DVD's to a clean, freshly-showered 64 GB (62.8, actually) ext3 partition (4K blocksize, defaults otherwise, journal included). I set up a top-level directory in this partition with 15 directories beneath it, one for each of my backup discs (whose contents range in size from 50 MB to 4.36 GB). I copied one archive to each directory, then unpacked them one at a time from the command line, removing the archive copy as I went. I ended up with about 15 GB of active data (25%).
I first configured kompare to use diff (w/no C/L options) running under KDE. As kdiff3 is kompare's preference, however, why is kdiff3 not already in the repos?
I'd not used it before, so I wasn't familiar with kompare's UI. I started out working with a few smaller subsets of the data I knew were near-perfect copies of each other and that wouldn't overload the filesystem. It seemed to act strangely; while I expected it to be well-optimised, both HD activity and CPU utilisation seemed extremely low for extended periods (and note my setup doesn't allow for a HDD LED for the HD on the controller card, where ALL the disk activity is going on).
After 3 runs in a row w/o a single errant file being found, I made a 2-byte mod to a small, non-critical text file that was part of the archive I was currently komparing, rebooting to make DAMNED sure cache was cleared, and reran kompare; identical results. The change STILL wasn't detected (the changed file still showed as being an exact copy of the original). The output I was getting was quite weird: usually, the 'kompare' would run at what seemed a rational speed; after a while a response screen would then open, *completely* devoid of data or messages. Immediately after that an odd dialogue box popped up; the title bar said "Error!", but the *message* was, basically, "No Duplicates Encountered." (or some such), or, more commonly, the same one I encountered repeatedly while searching the internet: "Could not parse diff output." (presumably because kompare still wasn't passing the proper parameters to diff). The program crashed about 1/2 the time (actually, give it a big enough block of data, and it'll crash every time). I was stunned 4 days later when ONE run (an exact duplicate of one I'd already attempted several times) resulted in "proper" output - *PERFECT*, with a complete and correct analysis - and completely unreproduceable, even after rebooting. It's ("It's" = proper analysis/output has) happened 3 times since, twice while working with data sets I would term 'trivial'.
So, in 2 weeks I got 3 runs w/o errors. I assure you I was trying at least 2 runs most days; a 1/2-dozen some days. By then, I also knew that kompare under KDE wasn't my only option - and I knew a bit more.
I use the "usual" repositories. When I finally checked diff's compile date, my jaw dropped: Sept. 3, *2002* !!! It's version 2.8.1; the current stable release is 3.4, and 3.5 is currently available for D/L (albeit not released). V. 2.8.1 works with the 2.6 kernel about as well as the original GWBasic compiler ('interpreter') does in WinXP...and may have been this way for a long time.
More research (difficult, given the age of what little kompare documentation is available on the web). The primary maintainer apparently got removed from maintaining the package in 2003 (and, I presume, other packages, as well) for what appeared to be 'apathy' (MY words). He 'forgot' to include an update after saying he would do so (a patch to pass the appropriate parameters to diff, hopefully fixing the "Could not parse diff output." message, and maybe even straighten out my anomolies, as well).
Kompare hasn't been updated since. Diff3 IS currently being maintained. Actually, even though diff3 has apparently replaced diff, *kompare* prefers kdiff3. For that matter, from my reading thus far, diff, diff3, vimdiff and cmp ALL may possibly be useable (the latter would require some scripting). Further, ALL the following may possibly be made able to work as wrappers (in decreasing order of likelihood, IMNSHO): kompare, krusader, meld, and emelFM2.
So, diff is broken, and it doesn't appear that it's going to be fixed...I personally was a bit consternated when I realised just how off-the-rails kompare was. I see a function such as that provided by kompare as both *critical* AND as a 'black box' function - it HAS to work. Just like the ALU MUST compute 2+2 = 4, or the 'computer' becomes a boat anchor...
So, I D/L'ed meld (for GNOME; it runs under KDE but no help is avalable), then emelFM2 (written for E17, I believe). I've spent the past week trying various combinations of (a) kompare, krusader, meld and emelFM2 as wrappers for diff under (b) KDE, GNOME, and E17. The results have been SO inconsistent it's scary. This includes both giving apparently proper results with a big job on rare occasion (but not consistently reproduceable), and VERY bizarrely, on one occasion, wiping a brand new, 64 *GB* ext3 partition CLEAN. I assure you the remainder of my testing will be on a dedicated partition! This HD is almost braad-new and has given me ZERO other trouble.
Meld was the most consistently performing diff setup I used (on any WM; it worked on them all).
I plan to spend the next 1-2 weeks doing some detailed and structured testing of all possible combos of wrapper/driver/WM, rather than just diff. I also plan to see if it's possible to pass command-line parameters to diff from kompare (if I have the time to spend ANY more w/kompare; kompare clearly isn't what I need - even though it had the . Yes, I *do* know how many combos of 4 wrappers, 4 drivers, and 3 WM's there are (48); my college major was statistics, LOL. And 48 test runs is adequate to test each combo, ONCE...
To me, this task is like big sort jobs were on mainframes a (human, not computer!) generation ago: potentially very large, critical tasks, the results of which aren't always easy to manually double-check. Surely many, if not most, users have a manner of doing this. Diff has apparently been broken for maybe 5 years and THAT wouldn't have gone unnoticed - am I one of the VERY few to even try to use kompare? What do the rest of you use?
Note that after locating and reading as much kompare documentation as possible (I read more BUG reports than anything), I made several important discoveries:
(a) kompare isn't really set up for binary files; it's intended for use with text files. You can specify an option to force a text-mode search, but you apparently canNOT do the reverse.
(b) It err'ed out comparing two M$ 'Word' files, stating they "were binary"...
(c) Worst of all, for me: These files have been archived to CD or DVD, usually repeatedly, and then copied back to disk (I've lost 3 good-sized archives this way - which does serve to somewhat justify my apparently obsessive need to backup files). Kompare does do individual file comparisons (ie, if you specify both files on the command line) byte-by-byte (block-by-block, whatever), but if you request that it compare *directories*, filename and size are all it considers (it appears from the sparse documentation I've seen that this is corrected in the *current* version, . The duplicate-file tool suite I used in Windows did an MD5 hash on *every* file, no matter the size; I *knew* when a bit error had creeped in, and usually knew fairly quickly. Not finding out you have a bad backup until it's the only copy of your data you have left is no good!
Anyone have any suggestions on doing this task efficiently and reliably in Arch?
Again, I believe this to be an upstream problem in a way, but my guess is that if we were using the *current* diffutils to match the KDE version (and a maintainer had done his job in a timely fashion) this bug would NOT exist. My advice, at least until Arch can get diff3 (or, preferably, kdiff3) packaged, STAY AWAY FROM kompare !!! At least with anything critical, at least until this issue is better understood.
Kompare (and diffutils, as well, IMO) needs to be removed from the 'public' repo's until it's close to fixed, at least. Just pkgbuild'ing the current diffutils version (or kdiff3!) is likely the easiest way out. Who knows, MAYBE I'll take a stab at that myself. No promises.
For ANYONE still reading, WOW! TIA. Really. Sorry for the tome.

[intro, backups, bla...]I BADLY need to unpack all this stuff, find and toss the duplicates, and truly organise (and efficiently backup) the remainder.
Ok, that's what it's all about.
I'd found a couple of useful tools in the Windows world years ago, but I don't buy software and the key piece of my suite was shareware that disabled itself after 30 days - not nearly enough time to plow through this boatload of bits.
Total Commander rocks.
[killed half a dozen paragrahps or so] It's possible that diff is the problem.
Contratulations. You managed to post 3K of text but still failed to mention what the problem is.
Subsequent googling has revealed that the diff version shipped with Arch likely hasn't been completely functional at all levels in almost *5 YEARS* now. Diff's codefile timestamp is Sept. 3, *2002*! Version 2.8.1 (3.4 is current - just like *kompare*'s current version is 3.4).
http://www.archlinux.org/packages/search/?q=diffutils
You will notice that package isn't flagged out-of-date. That's because the (still current) upstream version is (tadaa!) 2.8.1. Please tell us where you found that 3.4 version.
Additionally, directly below diff in that listing is diff3. Diff's codefile size is about 60K; diff3's is about 20K. *However*, they both have the same timestamp AND version # !!!
WTF??? What listing? You know that diff and diff3 are different programs but still part of the same upstream sources, don't you?
[non-relevant nonsense...] See how well kompare/diff work on YOUR system...
They work fine.
[kompare bashing]
Take a look at the URL, bugs.kde.org, not bugs.archlinux.org. Got it?
I copied the backups from CD's/DVD's to a clean, freshly-showered 64 GB (62.8, actually) ext3 partition (4K blocksize, defaults otherwise, journal included). I set up a top-level directory in this partition with 15 directories beneath it, one for each of my backup discs (whose contents range in size from 50 MB to 4.36 GB). I copied one archive to each directory, then unpacked them one at a time from the command line, removing the archive copy as I went. I ended up with about 15 GB of active data (25%).
I think I could rest my case already at this point.
I first configured kompare to use diff (w/no C/L options) running under KDE. As kdiff3 is kompare's preference, however, why is kdiff3 not already in the repos?
It is: community/kdiff3 0.9.91-1
(I will skip some paragraphs about the actual kompare usage and come back to that at the very end.)
I use the "usual" repositories. When I finally checked diff's compile date, my jaw dropped: Sept. 3, *2002* !!! It's version 2.8.1; the current stable release is 3.4, and 3.5 is currently available for D/L (albeit not released). V. 2.8.1 works with the 2.6 kernel about as well as the original GWBasic compiler ('interpreter') does in WinXP...and may have been this way for a long time.
Please quit that bullshit and show us version 3.4 of the GNU diffutils.
Kompare hasn't been updated since. Diff3 IS currently being maintained. Actually, even though diff3 has apparently replaced diff, *kompare* prefers kdiff3. For that matter, from my reading thus far, diff, diff3, vimdiff and cmp ALL may possibly be useable (the latter would require some scripting). Further, ALL the following may possibly be made able to work as wrappers (in decreasing order of likelihood, IMNSHO): kompare, krusader, meld, and emelFM2.
Check http://websvn.kde.org/ to follow the development progress of kompare, it's part of kdesdk. diff3 is from diffutils 2.8.1 and I wouldn't call that "maintained", but you already know that. It is obviously not a replacement for diff, did you ever read the manpages? And wow, a KDE program prefers to use another KDE program!
[killed quite a bit]Diff has apparently been broken for maybe 5 years and THAT wouldn't have gone unnoticed - am I one of the VERY few to even try to use kompare? What do the rest of you use?
Again, diff is fine and I'm using kompare (or kdiff3?) almost daily, in krusader.
(a) kompare isn't really set up for binary files; it's intended for use with text files. You can specify an option to force a text-mode search, but you apparently canNOT do the reverse.
(b) It err'ed out comparing two M$ 'Word' files, stating they "were binary"...
Genius. Comparing binary files is useless. If you used MS Office you're hosed, that simple. More useful advice at the end.
Anyone have any suggestions on doing this task efficiently and reliably in Arch?
Yep.
Again, I believe this to be an upstream problem in a way, but my guess is that if we were using the *current* diffutils to match the KDE version (and a maintainer had done his job in a timely fashion) this bug would NOT exist. My advice, at least until Arch can get diff3 (or, preferably, kdiff3) packaged, STAY AWAY FROM kompare !!! At least with anything critical, at least until this issue is better understood.
Upstream, right... diffutils have nothing to do with KDE at all... Arch has diff3 and kdiff3 packaged ... it's no 'issue' at all.
Okay, I apologize for that 'tone' of mine but I get pissed easily when wasting so much time on something as this.
I know your problem very well as I'm constantly backing up stuff, comparing directories and hunting duplicates.
After unpacking everything the first step to take is to run a comprehensive check for binary duplicates. My tool of choice for that task is Total Commander (Win32 shareware, no timeout, just a minor nag screen on start, works fine with Wine). Just a few random keyboard shortcuts you might find handy (see the help file for explanations): ctrl-b, ctrl-f1(-f6), ctrl-c,y, alt-f7
After killing them, go on to compare ("synchronize") similar directories, either with Total Commander, Krusader, rsync, diff -R, whatever.
If you encounter similar named files, check the dates and kill the older ones, or compare them if they're not binary.
And so on... you know best what kind of data you got and how to split it up.
Throwing plain diff on a set of thousands of files, possibly gigabytes is a huge waste of time and computing/power resources. Adding a frontend will make it crash most of the time, especially with binary files. I think using kdiff3 to compare the Arch Linux 0.8 base beta1 iso to the beta2 one alone should suffice. A few more gigabytes of RAM might help though.

Problems Setting up NFS

Hi.
I've been having problems setting up NFS on a LAN at home. I've read through all the Arch NFS-related threads and looked at (and tried some of) the suggestions, but without success.
What I'm trying to do is set up an NFS share on a wireless laptop to copy one user's files from the laptop to a wired workstation. The laptop is running Libranet 2.8.1. The workstation is running Arch Linux with the most up-to-date (as of today) software, including NFS.
I have the portmap, nfslock, and nfsd daemons running via rc.conf, set to run in that order.
I've re-installed nfs-utils and set up hosts.deny as follows:
# /etc/hosts.deny
ALL: ALL
# End of file
and hosts.allow as follows:
# /etc/hosts.allow
ALL: 192.168.0.0/255.255.255.0
ALL: LOCAL
# End of file
In other words, I want to allow access on the machine to anything running locally or on the LAN.
I have the shared directories successfully exported from the laptop (192.168.0.3), but I have not been able to mount the exported directories on the workstation (192.168.0.2).
The mount command I'm using at the workstation:
mount -t nfs -o rsize=8192,wsize=8192 192.168.0.3:/exports /exports
There is an /exports directory on both machines at root with root permissions. There is an /etc/exports file on the NFS server machine that gives asynchronous read/write permissions to 192.168.0.2 for the /exports directory.
I receive the following message:
mount: RPC: Program not registered
This appears to be a hosts.allow/hosts.deny type problem, but I can't figure out what I need to do to make RPC work properly.
Some additional information, just in case it's helpful:
This is the result if running rpcinfo:
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100024 1 udp 32790 status

Running ps shows that the following processes are running:
portmap
rpc.statd
nfsd

rpciod
rpc.mountd
Thanks for any help here!

Hi ravster.
Thanks for the suggestions. I had read the Arch NFS HowTo and did as you suggested get rcpinfo for the server machine. The Libranet NFS server is configured rather different since the NFS daemons are built into the default kernel.
Since I needed to complete the transfer immediately, I gave up for now trying to set up NFS and used netcat (!) instead to transfer the files from the Libranet laptop to the Arch workstation. The laptop will be converted to Arch Linux soon so I think I'll be able to clear things up soon. I haven't had any problems setting up NFS with homogeneous (i.e., all Arch or all Libranet) computer combinations.
Thanks again.

Unable to Open Bex report from SAP APO User Menu

Hi All,
I am an SAP APO consultant, and have not miuch expereice in BEx reporting. As APO uses Build in BI for reporting and pulling history from either external BW or R/3.
Now my issue all BEx reports we use are assigned ot my user menu and when I select a report, I would expect report to open but an excel sheet opens and closes and nothing happens. However I am able to open this reports from my desktop menu selecting Business explorer and Analyzer and linking my SAP system. I use Excel 2007 , Is this some compactibilty issue or is there anything I need to do?

Hi KV,
There's a couple of possible root cause why you dont see properly the Bex Report.
Can you share to me the APO version and the BW software component being used?
In case this is still in the 3.x, 4.x APO, I think, a separate BW add on is needed for you to run your BEx report properly. You can ask your basis team for this separate installation.
Btw, is this report working before, meaning was it pulled successfully already in the past?
Can you try doing this again in a separate workstation, as the BW add on is installed separately per workstation.
Its possible that this is also an auth issue that the user you are using is not capable enough to run BEx.
As of now, I have not encountered any Bex issue that is related with the Excel version, I have tried running Bex in Excel 2007 no issue also. I think it maybe more related with the OS you are using, if its in Vista already what I know is you need to add your excel as a trusted document before you can run bex fro Vista.
Let me think of other possibilities.
Hope this helps.

How to combine images from several different shoots into one

Have LR 3.6 for Win xp.
I have 4 differernt photo shoots that I want to combine into one big single catalogue. I want to be able to rank and choose images from all 4 shoots at the same time so I can get the best ones identified.
Each shoot is already in its separate catalogue but I cant figure out how to get all 4 shoots to show up at once so I can rank the best shots and maybe even make a collection of my best images from the 4 shoots.
How might I do this??
Thanks Suzzie

My primary suggestion is that you watch the many videos by Julianne Kost provided in the Adobe site about organizing in the Library Module in LR 4, or read one of the many good LR books. If you want to venture on your own here's a very shorthand description of one of many ways to do what you want. Choose which Catalog you want to use. Open that Catalog and choose "Import from Another Catalog" under the File Menu in the Library Module. Select the images and import them to your chosen main catalog. Once all are in the same Catalog either Keyword all similar images you wish to compare, or make separate Collections of each one. Use the Compare function in the Library ("c" key) and eliminate the one you don't want. Unless you have one client viewing your images in LR and you don't want them to see that you have other images for other clients, I would suggest you use only a single catalog from here on out.

MacBook Pro HD issues; won't boot to any drive; need to recover data

*Apologies in advance for the lengthy post. I just want to be sure I include as much detail as possible. Thanks in advance for reading all of this and offering any thoughts and suggestions.
I have a 13-inch late 2011 MacBook Pro running OS 10.7.
The computer recently began booting slower and slower until finally one day it did nothing but show the gray boot screen with the apple and a spinning circle and/or progress bar at the bottom. It won't do anything else. I assume it's the HD; no surprise there. What's killing me is that no matter what I do, I can't boot to any disk, internal or external, can't mount it in target disk mode, and can't repair it or recover data, which is a first for me with any HD. However, the computer still clearly sees the drive, and the drive sounds and runs normally (meaning no clicks; appropriate amount of whirs and such).
What I've done so far:
Reset PRAM — no help
Reset SMC — no help
Boot in Safe Mode — same result as regular boot: gray logo screen with spinning wheel
Disk Utility message:
Verify Disk — "Error: This disk nees to be repaired. Click Repair Disk."
Repair Disk — gets as far as "Checking catalog file" then shows "Keys out of order". Next is "Rebuilding catalog B-tree." Then "The volume Macintosh HD could not be repaired."
fsck — same as Disk Utility: "Keys out of order (4, 22016)", "Rebuilding catalog B-tree", then "The volume Macintosh HD could not be repaired." FILE SYSTEM WAS MODIFIED." ...over and over again
If I hold Option while starting the computer, it gives me only two drives to boot from, regardless of any other external HDs or flash drives I have attached: Macintosh HD (internal), and Recovery HD (internal partition). If I choose Macintosh HD, it's hit or miss whether it prompts the Disk Utility screen or just gray-screens forever. If I choose Recovery HD, it successfully runs Disk Utility every time. Here's the thing, though — if I attach an external HD, it doesn't see it during the initial Option-startup. However, from Disk Utility I'm able to select a startup disk from the menu to restart into. It sees the externals in there every time and lets me select them as startup disks, but upon restart it returns to the gray Apple logo screen with spinning wheel and/or progress bar at bottom. Sometimes it also sees the internal Macintosh HD here, but selecting that is useless. I can't actually boot from any disk, internal or external, running full OS or even just recovery software.
I've tried using TechTool Pro 8's edisk and ProToGo bootable drives, but again, the MacBook only sees them from Disk Utility only (not on Option-start), and I can select them, but it doesn't actually boot to them; it reverts back to gray screen.
I've installed a full version of OS 10.10.2 on an external hard drive, complete with DiskWarrior 4 on it, but same problem as above — it sees it in the "Select Startup Disk" menu, but not in the initial Option-start or successful reboot.
I've tried booting from a DiskWarrior 4 DVD using C-startup. It recognizes and spins the DVD from the get-go. Eventually it boots to it (after about 20 minutes or so of reading the DVD). I'm able to launch DiskWarrior 4 and start a rebuild. However, it goes all the way through "Step 6: Constructing optimized replacement directory... Overlapped files detected: 7 ...Step 7: Finishing construction ...Step 8: Reading from disc, one moment please..." and then the computer kernel panicked. This happened several times. I reset the PRAM again, then retried DiskWarrior DVD boot, this avoided a kernel panic and it got as far as "Comparing directories... Step 9: Recording any file or folder differences; 3,449,089,956 tests..." and then DiskWarrior and the computer both freeze and I have to force shutdown.
The drive will not mount to another laptop in Target Disk Mode.
Disk Arbitrator immediately sees the the faulty laptop HD, but won't let me mount or unmount it. It's just there, grayed out.
Data Rescue 4 is able to see the faulty laptop HD through Target Disk Mode, even though the drive itself will not mount to my desktop. I am able to scan the drive using DR4, and start a data recovery process. However, DR4 is dumping all recovered data into "User Defined" ai (Adobe Illustrator) files, which makes absolutely no sense at all. What's more, the files aren't able to be opened by any program. Even files that it hasn't recovered into ai files, like txt and mpegs, cannot be opened. I've tried recovering from both the drive itself and from a clone of the drive (made through DR4), with the same result each time.
So, all of that said, I guess my first question is what the **** is going on? The drive mechanically is functioning fine, but there seems to be an issue with its readability (and the directory/files?).
What's more, why won't this laptop mount ANY drive? I should be able to Option-boot into any drive, especially if the USB ports, drives, and OS's are all fully functional, right? Is there any workaround I'm missing? Even if the internal drive and data are just screwed, what's causing a total lack of mounting or booting of any drive, internal or external?

Holy crap, I got it to work.
Essentially, I just waited until DiskWarrior reached Step 9 and told it to skip the step before it had a chance to freeze. It skipped successfully, moved on, rebuilt and replaced the faulty directory files.
So far the computer is booting like normal, I can log in, and I'm currently copying all of the data to an external as I type this.
I still have no idea why the computer wouldn't mount or boot to any drive, but I guess I'll deal with that later.

Can I move one of my subscriptions to another Adobe ID?

Sorry, I've tried to ask this through the "Available 24/7" chat, but it just says "Chat not available now" (this has happened the last 2 times I tried chat, so I guess the 24/7 thing really needs to be changed).
I have 2 subscriptions through the same Adobe ID. One is the full Creative Cloud, the other is just Acrobat Pro. I did this as I need Acrobat open on 2 workstations at work. The problem is that this causes a complete PITA. I have CC installed on my Macbook Retina for use out of the office and also installed on a heavy duty graphics workstation at work (per the license terms!). All was absolutely fine until I decided that a separate workstation also needed Acrobat on it. So I licensed another Acrobat Pro licence using the same Adobe ID thinking this was the right thing to do. What now happens is that when I try to use Acrobat on the 2nd workstation it says that it's already installed on 2 other computers. I tried telling it to force a logout on the other computers and that allowed me to use Acrobat Pro on the 2nd workstation. Of course the CC desktop app then freaks out on the original workstation and it takes about 30 minutes of repeatedly logging in and re "licensing" CC to get it working again. This is with me exiting all CC apps on my Macbook Pro (and even exiting the CC app itself) BEFORE attempting to use anything on either of the 2 workstations. All CC apps are on the latest version (auto update is on on all).
So, can I pretty please move the Acrobat Pro license to a different Adobe ID so that I can go back to pre Creative Cloud meltdown mode?

The camera connection kit can only be used to import photo/video files from a camera, SD card or USB flash drive. You can't import other types of files. You can't export any type of files using the camera connection kit.
There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.
Another option:
