While stumbling around on the net in frustration trying to answer this question, I ran into http://owncloud.org/. I was very skeptical at first as it seemed like a very new project. I figured it was worth a try though.

As I prepared for the install (by reading all the docs I could find about the project), I got really super excited. I was going to toss it up on my virtual machine but I got so excited that I ended up doing the install to my ‘production’ system (well about as “production” as it gets for my personal home system…still I don’t like to muck it up). All went well and it was quite easy to get working really fast.

I uploaded a few files and enabled a few plugins and thought ‘Ok. Not perfect. But a decent start.’ As I poked around on the site I really began to like it.

Here is a run down of the plugins I am using.

Files:
Simple enough. You can create text files or directories and you can upload files. When I created a text file I was able to edit it with a basic editor that does most everything I need. I created a few directories and uploaded a few things. The download button worked for files but not for folders. The share button was nice as i could share with a person, group, or public. Most seemed to work as expected.

The only two things I really feel should be addressed are:
1) When uploading a file, all I see is a spinning icon. No display of progress or how much longer the upload will take.
2) It would be nice if I could upload a folder. I tried a few things but they didn’t seem to work. Uploading a file just works, but folders were not working.

Music:
I was surprised and delighted to see that after uploading a (legit!) music MP3 download in the Files section that the tracks appeared in the Music section. The player was working and everything seemed pretty good. The interface was a bit kludgy but it wasn’t hard to figure out. I decided to upload more music. A new album I got for Christmas. An album I ripped to FLAC (like I do all my CD’s). A good 90% of my music collection is in FLAC. The music player stopped working. It didn’t start working until I deleted all the FLAC files.

This was highly disappointing and in my opinon really needs to be addressed…

Contacts:
Simple interface. Handles all the contact information one would expect it to hold.

I do wish there was a notes section.

Calendar:
I set a few appointments/events and while it worked I don’t know how much I will end up using it. I am going to try to use it more because something seems off about it but I can’t place what. Maybe it is just me. But until I can figure out what is bothering me, I can’t write a just and descriptive review of it.

Gallery:
This didn’t seem to auto update after uploading files. Maybe it just had not had the chance to scan. However, a manual scan picked up the files. The preview pictures seemed to be only partial center portions of the image and as such the thumbnail view didn’t really show anything useful in the pics I uploaded. However, clicking on them brought up the full image and I was very please about how easy it was to navigate.

No comments on things to do here.

Bookmarks:
Basic bookmarking feature. Nothing too special. Works just as I expected it to. I found another webpost suggesting that I should be able to link my browser on KDE (Rekonq) to the bookmarks feature. I have not tried this yet, but if it does work that would be very nice as it would be my own bookmark sharing utility.

Over all I am very impressed and I can’t wait to see what they do in the future.

System->Administration->Disk Utility

Now because I don’t want to seem too childish in whining about the results, I will not post the vendor names.

As a standard benchmark, a 5$ USB disk from Newegg.

I found it very interesting (and worthy of this post) simply because of the fact that these flash drives have such terrible write speeds. I understand that each company handed out 100′s of these flash drives and that 5$ each would add up quickly so they went for a much cheaper alternative. Still, it is rather annoying that the write speeds are so terrible. Especially on a 4GB drive. That is a decent amount of space for the files I carry around but at a max of 2.3MB/s transferring files to fill that would be roughly half an hour at peak speeds. Closer to an hour more than likely.

Then again, I really can’t complain too much. I did get a bunch of free flash drives that I am sure I can find a use for.

Thanks to all the vendors who gave me free schwag!

Anyway, I have been completely submerged with that project and basic day-to-day life and I have not had much of anything to post recently. Now that it is over (well till work sends me to the next round of RH training), I am finally getting around to working on some of my other projects. Hopefully I will be posting more about those as I go along.

I am not the best at this but I have found it entertaining. I am a bit disappointed in the GPU and wished it was faster, however, I am really impressed at the speed of the dual core 1.6Ghz processor/Radeon 6310 considering how little power it draws.

I am doing this experiment on Ubuntu and ran into a few issues that I thought I would post here.

First, I downloaded and installed the latest ATI driver set. Second, I downloaded AMD’s Accelerated Parallel Processing (APP) SDK.

http://support.amd.com/us/gpudownload/Pages/index.aspx

http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx

I installed the drivers and made sure they were working. After that I extracted the files out of the SDK. AMD provides a install script that I ran with sudo privileges” `sudo Install-AMD-APP.sh`. This installed the SDK to /opt/AMDAPP and it added the PATH to /etc/profile. I had to install a few packages before I could get the samples to compile.

`sudo apt-get install libglew1.5-dev libglu1-mesa-dev libgl1-mesa-dev mesa-common-dev libdrm-dev libxau-dev libx11-dev build-essential make`

There may be more packages required. I tried to list the important ones, but I may have missed a few as I did an install of basic compilers before undertaking this OpenCL project.

Once all the tools were in place, I granted access to the /opt/AMDAPP for my user and started the compile process.

`sudo chmod -R user:user /opt/AMDAPP`
`cd /opt/AMDAPP`
`make`
`cd /opt/AMDAPP/samples/opencl/bin`

If everything compiled and worked out then all the sample binaries should be in that directory and should be executable.

If anyone has any comments or suggestions, please post below.

Two things actually did happen to me over this past Memorial Day weekend. Two things that were such non-events that I almost didn’t remember I did them. Even after I remembered, it took a comparison between Linux and another OS before it hit me of just how big of a deal this actually was to me. Once the full realization of what I had done sunk in I knew right away that I love Linux and all the people who contribute to it just a little more then I had before.

Non-Event #1

I had a 64bit Debian Squeeze install. Nothing special on it, in fact it was a very stripped down install. This was primarily a “Repository Server” for me. It was my local mirror for Debian Lenny and Squeeze, Ubuntu 10.04, CentOS 5, and Scientific Linux 6. A big hard drive with a very little OS footprint. Well, it wasn’t on a battery backup because I didn’t care enough. We got hit with a brown out that blew the power supply. My bad luck comes in to play with the fact that the power supply is a special one that I don’t have a replacement for and to buy a replacement would cost as much as the computer originally cost me.

So what to do? Well I pulled the drive out, and plugged it into a less powerful spare box. Booted the box, and the only major change was that instead of my two network cards being eth0 and eth1, they were now eth2 and eth3. The rest of the system ran just fine. I made a few changes to the network card properties and as far the network/computer were concerned the box wasn’t any different. My scripts all continued to run, the other computers still used it for pulling updates, and every one went on doing their thing. A complete non-event.

What makes this special then?

Well it occurred to me that many years ago when I still had a Windows XP box and my motherboard died, I had tried to take my hard drive out and plug it into a new system. Not only did it not work, but it complained that I had invalidated my license key! I had to do a backup (with a Live Linux cd) followed by a re-install. A co-worker pointed out that when they tried doing it with Windows Vista, they got the logo with the scrolling bar and it would never boot any further. They too had to re-install. In fact, from everyone in my (albeit very limited) group no one could think of a time when they were able to do this successfully with Windows *without* using a 3rd party migration tool.

This is why it was a non-event to me that was so very special. My Linux swap had no licensing issues. There was no halted booting. There was no re-install of my OS and programs with near endless updates for the updates. There was no pain, no suffering, no gnashing of teeth, nor was there even a sign of a feint hint of a headache in the foreseeable future. That’s how easy it was. I just swapped the disk and had my server back up and running with nearly no downtime or incident!

I Love Linux.

Non-Event #2
My laptop runs an older version of Ubuntu (because I am too dang lazy to update…thats why). It has been behaving rather odd recently. I knew it was the hard drive because when things went really wrong I could hear it slam the arm against the drive and spin down just moments before the laptop would hang. I have been too lazy to upgrade, so that should tell you that I don’t care enough about this laptop to swap the hard drives. Well I fired up a program by clicking its GUI icon and nothing happened. Huh. Try it again. Nothing. Try it from the command line and it refused to run. The heck? So just for grins I tried to run it with gdb. Oh boy, was it not happy. Huh. It ran fine earlier this morning. A random thought made me check the md5sum of the file vs what it was supposed to be. It didn’t match. Great. So I ran badblocks and guess what? I had a BUNCH of them! Arg. I knew it was coming so I couldn’t blame anyone but myself.

I turned on MythTV and watched more Science Fiction shows while I pulled the 80GB drive out of my laptop. Using a laptop-2-USB adapter I plugged it into my main computer. I found a smaller 40GB laptop drive that was in great shape, and I plugged it into my main computer with another adapter. I inspected the bad drive and it seemed that all the problems were in the 10GB root partition. There were three partitions: root, a small swap, and the rest in the home partition. For some reason the big home partition didn’t register problems, yet.

Using dd with the “conv=noerror,sync” option (lots of bad sectors that dd had to replace with 0′s) I copied the root parition (10GB) to the 40GB drive. I created a small 2GB swap partition on the 40GB drive, and dumped the rest into /home. On the 80GB drive /home had most of the space but I was only using ~5GB. Therefore, I mounted the two /home partitions and rsynced the data with proper permissions (no errors were reported). I had to edit the /etc/fstab of the new drive to edit the UUID’s of the new swap and home partition but that was it. I slapped the new drive into the laptop and booted it up. No problems at all. However, I did still have bad sections of 0′s, remember? And these 0′s were in the midst of various programs which would cause plenty of problems. I ran debsums and sure enough several packages reported problems. I reinstalled those packages and re-ran debsums. All good!

In total with all the file transfers, it was only about 3 hours while my attention was mostly watching a Science Fiction show that was almost as un-memorable as the replacing of the drive. Now my laptop has a working hard drive in it and appears to be in great shape.

What makes this special then?

As I was discussing this with my co-workers we came up with several pitfalls had this been attempted under Windows.

First, Windows doesn’t have a separate partition capabilities for its ‘Documents and Settings’ aka /home information (at least none that we are aware of without using third party tools of which at least one of us has tried with little success). Therefore the separating of all the users files from system files would have been quite painful.

Second, while a dd of a windows drive would have worked it would have a) required a Linux box or live cd (but we may just not know of a Microsoft alternative though I am sure there are paid-for 3rd party tools) and b) would have required shrinking the NTFS partition to the smaller drive size before transferring. The shrinking of the file system *could* have resulted in _more_ corruption depending on how it was done.

Third, program installation and program file tracking in Windows is absolutely terrible. There is NO other way of saying that without resorting to foul and inappropriate language. Unfortunately that language is almost necessary to describe how terrible Windows is at tracking and installing programs. Microsoft just simply doesn’t have a good package manager (they don’t even have something that rates higher then terrible). Therefore, even after a partition transfer with bad sectors there would be no way to check all the files installed by various programs to determine which files/programs needed to be re-installed. A bit-by-bit copy would have been just as broken.

Fourth, as discussed earlier in Non-Event #1 transferring installs between computers can be a huge pain. Now in this case since all the hardware was the same except for the hard drive, hopefully one wouldn’t have problems. Still how many people have changed a few items in their computer and had to re-activate their Windows license? A quick Google search says A LOT! I am glad this threat doesn’t hang over me in the Linux world.

Since a bit-by-bit copy doesn’t seem to have very good chance of working in the Windows world (in this example), maybe a migration would work. However, we are not aware of a good Microsoft provided migration tool. You would have to install Windows to the new drive, then use a third party tool (which would probably cost even more money) to migrate your programs, files, and tools.

Since migration is iffy and going to cost more money, the only alternative that has any good chance of working without paying more money would be to do a complete re-install. A re-install that would take a LOT of time and effort with FAR too many updates of the updates of the updates. And that is just for Windows. After that you have to install all of your programs and transfer your files.

Regardless of how you manage to rebuild the Windows laptop, it is going to be painful. It is VERY doubtful it could have been done in the same time frame. Especially if one devotes time and attention to watching a movie (or should I say multiple movies with a Windows install). The only hope of doing it in that time frame is if you already have all the third party tools needed. Even if you could get it all copied, you still have ZERO ways of checking your programs to find out which ones got corrupted, much less a easy way of repairing those files. To put it bluntly, some one in this position is screwed.

I guarantee that *I* could not have done that much work and effort over something that should be so trivial and easy without going stabby-stabby on the laptop and/or the closest Windows developer I could find. Under Linux it was a non-event. It just worked. Nothing at all to get frustrated about.

Two non-events that took very little of my time. Two non-events that would have destroyed my weekend had I been a Windows user. My sincere thanks to all those who put their time and effort into Linux to make these non-events.

I Love Linux. It just works.

Nevertheless, I didn’t want to have bad information posted on my blog so I decided to update.

If you try to use my old post for compiling on SL6 or CentOS you end up with an error message like reader mailo got:
make[2]: Nothing to be done for `install-exec-am’.
make[2]: Nothing to be done for `install-data-am’.
make[2]: Leaving directory `/usr/src/redhat/BUILD/zabbix-1.8.5′
make[1]: Leaving directory `/usr/src/redhat/BUILD/zabbix-1.8.5′
+ install misc/conf/zabbix_agent.conf misc/conf/zabbix_agentd misc/conf/zabbix_agentd.conf misc/conf/zabbix_agentd.win.conf misc/conf/zabbix_server.conf misc/conf/zabbix_proxy.conf /var/tmp/zabbix-1.8.5-root/etc/zabbix
install: omitting directory `misc/conf/zabbix_agentd’
error: Bad exit status from /var/tmp/rpm-tmp.54232 (%install)
RPM build errors:
Bad exit status from /var/tmp/rpm-tmp.54232 (%install)

This is due to a new directory structure in misc/conf/zabbix_agentd. Lennart at Andrew Farley's blog caught the fix.

Here are the steps to compile now.
1) Download the zabbix spec file into ~/rpmbuild/SPECS/

2) Edit the spec file
2a) Change line 6 from "Version: 1.8.3" to "Version: 1.8.5"
2b) Change line 382 from "install misc/conf/zabbix_{a*,s*,p*} $RPM_BUILD_ROOT%{_sysconfdir}" to "install misc/conf/zabbix_{a*,s*,p*}.conf* $RPM_BUILD_ROOT%{_sysconfdir}"

3) Download Zabbix 1.8.5 from zabbix.com into ~/rpmbuild/SOURCES/

4) Download the patch file into ~/rpmbuild/SOURCES/

5) Build your RPMS!

So all together on the command line:
$ cd ~/rpmbuild/SPECS/
$ wget http://repo.andrewfarley.com/centos/specs/zabbix.spec
$ sed -e 's/1.8.3/1.8.5/' -i zabbix.spec
$ sed -e 's/p\*\}\ /p\*\}.conf\*\ /' -i zabbix.spec
$ cd ~/rpmbuild/SOURCES/
$ wget http://repo.andrewfarley.com/centos/specs/zabbix-centos-log-and-pid-paths.patch
$ wget (find download link from here)
$ cd ~/rpmbuild/SPECS/
$ rpmbuild -bb --target=`uname -m` zabbix.spec

That should be it! So far this is working for me. If I come across any other issues I will fix them here.

Once again, major props to Andrew. And props to Lennart for the fix.

[EDIT] Eric G built RPMs for 1.8.5 and 1.9.3 below in the comments. If you just want to install the RPMs instead of building from source you should be able to use his repo. Thanks Eric G!

I got introduced to Shmoocon and am planning on attending that this year. I also got to meet several craftsmen/women, artists, and shops that are in the OKC area. I can’t wait to explore their shops.

While I did enjoy the fact that they had performers playing in the atrium all day, they didn’t have the speakers setup properly for speech. The music groups sounded great, however, the groups that just talked sounded muffled and muted if you weren’t next to them. They had three guys up there one time and they looked like they were having a great time but I couldn’t understand a word they were saying. Something about bad movies I think. They could have just been making Charlie Brown teacher noises for all I know. Wha-wa-wa-wa-waaa

I did have issues with how the event was run. Every time I asked a question to one of the staff it seemed that they had to call someone else. In fact, it seemed to be the same 2 or 3 people that questions were asked to. One guy (attendee) I talked to kept asking the staff about the event programs which didn’t show up until almost 5pm on Saturday. No one seemed to be able to give a reason for why besides issues with the printer (again, only a few people seemed to know about what was going on). The guy didn’t seem too thrilled as he claimed they had paid for an ad in the program. Not only was the program missing for the majority of the event, but he didn’t see the ad in the program. I heard them offer a refund, but still…Eek! Feel bad for the guy. He seemed to be excited about the ad too…

**Warning: over heard conversation**
It wasn’t just me who noticed the confusion. Several of the vendors were openly complaining about the vendor room to each other. One even joked about packing up half way through the day. I don’t know how much of that was HaHa joking vs joking-but-kinda-serious-too. Either way it can’t be good when the vendors joke like that in front of staff and attendees.

I understand that this was their first big event and believe me, I don’t know if I could have done as good of a job. However, having attended several big events I do kinda understand how things should work. There should be a hierarchy chain of command. There should be certain people responsible for certain actions/items/events and held responsible for those actions/items/events. The people who know every detail should NOT be running around putting out fires as that should be COMPLETELY delegated out to another responsible party. They should only be there to oversee the whole picture.

Relying on a handful of people to run the whole event HAS to be stressful on everyone. Stressful for the people doing everything, stressful for the people relying on leadership, stressful for the vendors, and aggravating for the attendees.

I can’t wait for next year. I really hope that they don’t get discouraged by the craziness and they they learn from it to put on a better show next year.

I also really hope that they get Abney Park next year. But that is probably just a fanboy fantasy on my part I was REALLY pleased to hear several people playing Abney Park on their portable music players though.

This year was so much better then last year. They really stepped up their game and put on a great weekend*. Sure there were a few hic-ups with things, but they seemed to recover pretty fast.

* Not that last year was bad, they just really improved.

The only complaint that I have is that they put on the tutorial sessions on Friday morning. I wasn’t able to convince work to let me off for the day and while talking to a few others on Saturday it seemed that they also had similar complaints about being unable to make it.

Oh well. Hopefully they can move the Friday events to the afternoon or on Sunday next year…or that I can convince work to give me the day off

Having worked with Linux personally and professionally for over 11 years now along with Unix, HPUX, Irix, and Solaris on occasion, I thought I would offer my thoughts on the article. Especially since he seems to have gotten really close to describing me without ever meeting me…

“No. 1: We don’t use sudo”
The first ‘Wow, that is what I do’ moment was near immediate. The quote “the first thing we do is sudo su -” pretty much describes me to a ‘T’. That is almost always the first command I run when I boot into an Ubuntu live cd.

The only “objection” I have to this is, there are certain times when sudo is necessary. I admin a few servers that are as locked down as tight as we can get them. The root account is locked in every way. The root account and all activity are tracked and monitored. Any admin running commands as root (or su), get flagged on our monitoring system. The only way to work on that box is sudo for the sole purpose of tracking and monitoring what each admin does on that box. It works well and that is about the only time I use sudo.

“No. 2: We use vi”
Damn straight.
Thanks to the Single UNIX Specification, I KNOW that vi is going to be on every system by default. So I KNOW that I have a great editor at my fingertips no matter what system I am on.

“No. 3: We wield regular expressions like weapons”
XKCD jokes aside, if one knows how to wield and document regular expressions one can do near anything.

“No. 4: We’re inherently lazy”
Fully agree. This is why I do everything I can to master the Bash shell. I can automate so much of what needs to be done it isn’t even funny. It may take me a while, and I monitor everything closely, but it gets done and chances are good I don’t have to do it again. Which means I can devote my time to something else AND I have another solution/script in my code repository I can re-use later if need be with little effort.
Oh! Also, screw Angry Birds. Frozen Bubble is where it is at.

“No. 5: We prefer elegant solutions”
I am just going to re-quote Paul on this one because he nailed it perfectly.
“If there are several ways to fix a problem or achieve a goal, we’ll opt to spend more time developing a solution that encompasses the actual problem and preventing future issues than simply whipping out a Band-Aid. This is related to the fact that we loathe revisiting a problem we’ve already marked “solved” in our minds. We figure that if we can eliminate future problems now by thinking a few steps ahead, we’ll have less to do down the road. We’re usually right.”
Can I get an Amen? Amen!

“No. 6: We generally assume the problem is with whomever is asking the question”
I don’t like to be thought of as arrogant, so I try not to be even if others think I have earned it. I will investigate and I will honestly try to find a solution to a one-off-random-happen-chance error, but if I can’t reproduce it chances are I am going to chalk it up to user error. Why? Because it almost always is (sorry; just a bit of the arrogance slipping out). If it happens twice, I will set traps and monitor log files. If I can catch the error, chances are really good that I am going to do what I can to find a solution as long as time, effort, and $$$ permit. I also HATE the Band-Aid philosophy as an admin. I want an elegant permanent solution if I can get one.

“No. 7: We have more in common with medical examiners than doctors”
Once again he hits the nail on the head. Ties right in with the last point. I have detailed monitoring setup with Zabbix for my network and my systems and I expand its capabilities and items it monitors weekly. When something happens, I want the log files to tell me what happened, why, and what I need to do to prevent it from happening again.

“No. 8: We know more about Windows than we’ll ever let on”
Damn monkeys that call themselves Windows Admins. Don’t get me wrong, there are plenty of smart Windows Admins. However, the really bad ones that piss me off are the ones that cause all the trouble. The idiots that really drive me crazy are the ones that wave their MCSE’s around like it is proof they know something, then are completely incapable of thinking outside of the step-by-step guide given to them. These idiots often say ‘It works! Now don’t touch it!’ and won’t do even the basics such as applying security updates (MCSE = Making Computers Susceptible to Exploit). If you ask them to do basic tasks they give stupid excuses (or worse promises) to make you leave so they can hurry back to their desktop games (aka MCSE = Minesweeper Consultant / Solitaire Expert). They have no idea what they are doing. They click this button, then click that button, then click agree, next, next, finish, and then assume that everything is ok. Don’t bother wasting your time telling them they configured something wrong. They will dig up some tutorial book for Windows NT 3.5 as proof for their Windows Server 2008 configuration. These idiots are so scared that someone will force them to learn something new that they are usually the most vicious defenders of buying off the shelf software (God help you if you get caught in their fanatics if someone suggest they learn a new OS! Even another version of MS Windows will set them off!). These idiot admins CAN’T fix problems on their own so they HAVE to buy support and they absolutely depend on management buying whatever they need (MCSE = Management Conned by Something Expensive).
This means whenever something of theirs breaks and that breakage even hints at disturbing anything in the Linux realm, ___I___ have to fix it. Nothing would make me happier then to never touch another Windows box and ditch any and all ‘knowledge’ I have of it, but as long as these idiots are still around I will probably have to fix their servers for them.

PS: Why is it that for every MCSE that I meet who actually knows what he is talking about, I end up dealing with 10 who I am surprised that they managed to fill out their name on the test correctly? Also, if the test is so damn easy and cheap that these idiots can get one, why is it such a highly esteemed certification? That still baffles me to no end….

“No. 9: Rebooting is almost never an option”
I wouldn’t say ‘never an option’…but the last reboots I had were due to kernel updates, a bad nic card I needed to replace, and to run a diagnostic on the root drive that required it to be offline. I will agree with this statement “If the problem occurred once and was “fixed” by a reboot, it’ll happen again.” I have seen this with Windows, OSX, and Linux. Something goes weird and the user reboots every time. Soon they are rebooting several times a day because they never fixed the problem.

My servers have high uptime because they are stable and I know everything running on them and how to fix those programs/services when (if) they have issues. My uptimes can span years and are on legit servers. Not a box that sits in the corner of the room that no one ever logs into.

On the flip side of the coin, I know someone who was hacked pretty bad because he refused to update while he was chasing the holy 5 nines. The hole they got in through had been patched over 9 months previous to the hack. This is why I watch all the security lists for Debian and CentOS (the distros on my servers) and I am more then willing to sacrifice a silly uptime number to apply a security patch.

Lastly, I can’t think of a better way to end this then the statement he had. So I am just going to quote Paul one last time.

“If some of these traits seem antisocial or difficult to understand from a lay perspective, that’s because they are. Where others may see intractable, overly difficult methods, we see enlightenment, born of years of learning, experience, and most of all, logic.”

I am totally going to swipe their code….
1) New way of reading files
# Old way
while read line
array[i]="$line"
i=$((i + 1))
done < file
#New way
mapfile array < file

2) Just visit the website and read up part 3 on the ‘read’ command
In short, you can now supply default text in the read command.
read -e -p "What is your user name? " -i $USER

Thats all for now. I am sure I will find more new tidbits soon.
