Backup Notes

2007 Jul 13, 8:30I bought an external backup drive a few weekends ago. I've previously setup a Subversion repository so I decided to move everything into the repository and then back it up. So in went the contents of all of my %USERPROFILE% and ~ directories with a bit of sorting and pruning. Not too much though given its much easier to dump in everything and search for what I want then to take the time to examine and grade each file. What follows are the notes I took while setting this up. It takes me a bit of time to look up the help on each command so I figure I'll write it all down here for the benefit of myself and potentially others...

Setting Up the Backup Drive For Linux
I first changed the filesystem on the drive to ext3. I plugged it into my USB2.0 port and ran fdisk:

sudo fdisk /dev/sda

Useful commands I used to do this follow mostly in order:

m

help

p

print current partitions

d

delete current partition

n

create new partition (I used the defaults)

w

write changes and exit

Then I formatted for ext3.

sudo mkfs.ext3 /dev/sda1

I made it easy to mount:

sudo vim /etc/fstab
# added line to end:
/dev/sda1 /media/backup ext3 rw,user,noauto 0 0

I setup the directory structure on the disk

mount /media/backup
sudo mkdir /media/backup/users
sudo mkdir /media/backup/users/dave
sudo chown dave:dave /media/backup/users/dave

After all that its easy to make a copy of the Subversion repository:

mount /media/backup
cp -Rv /home/dave/svn /media/backup/users/dave/
umount /media/backup

Next on the agenda is to add a cron job to do this regularly.

Subversion Command Reference
On a machine that has local access to the Subversion repository you can check out a specific subdirectory as follows using the file scheme:

svn co file:///home/dave/svn/trunk/web/dave%40deletethis.net/public_html

Note also that although one of my directories is named 'dave@deletethis.net' Subversion requires the '@' to be percent-encoded.
Other useful subversion commands:

svn help

help

svn list file:///home/dave/svn/

list all files in root dir of svn depot

svn list -R file:///home/dave/svn/

list all files in svn depot

svn list -R file:///home/dave/svn/ | grep \/$

list all directories

svn status

List status of all files in the working copy directory as in - modified, not in repository, etc

svn update

Brings the working copy up to date wrt the repository

svn commit

Commit changes from the working copy to the repository

svn add / move / delete

Perform the specified action -- occurs immediately

Setting up Windows Client for Auto Auth into SVN
When using an SVN client on Windows via svn+ssh its useful to have the Windows automatically generate connections to the SVN server. I use putty on my Windows machines so I read the directions on using public keys with putty.

putty.exe dave@deletethis.net
cd .ssh
vim authorized_keys # leave the putty window open for now
puttygen.exe
Click the 'generate' button
Move the mouse around until finished
Copy text in 'Public key for pasting into OpenSSH authorized_keys file:' to putty window & save & close putty window
Enter Key passphrase & Comment in puttygen
Save the private key somewhere private
pageant.exe
'Add Key' the private key just saved.

Checking out using Tortoise SVN
On one of my Windows machines I've already installed Tortoise SVN. Checking out from my SVN repository was really easy. I just right clicked in Explorer in a directory and selected "SVN Checkout...". Then in the following dialog I entered the svn URI:

svn+ssh://dave@deletethis.net/home/dave/svn/trunk/web/dave%40deletethis.net/public_html/

Note again that the '@' that is part of the directory name is percent-encoded as '%40' while the '@' in the userinfo is not.

Windows Command Line Check Out
On my media center I didn't want to install Tortoise SVN so rather I used the command line tool. I setup pageant like before the only difficulty was getting the SVN command line tool to use putty. With the default configuration you can use the SVN_SSH environment variable to point at a compliant SSH command line tool. The trick is that its interpreted as a backslash escaped string. So I set mine thusly:

set SVN_SSH=C:\\users\\dave\\bin\\putty\\plink.exe

The escaping solved the vague error I received about not being able to create the tunnel.backup technical personal windows svn linux subversion

MoHo Living

2007 May 13, 12:16My parents and grandmother came to visit the weekend before this current weekend, starting Friday May 4th. They arrived via their new motor-home which is quite the machine. Of course its my parents motor-home so its very well decorated inside including drapes and mini-chandelier. I didn't have a memory card for my camera at the time but I'm sure my parents will put up photos on their new blog dedicated to their motor-home at some point in the future.

At any rate, they parked the motor-home in an RV park in Issaquah so that Friday night I drove over to them and we ate at the conveniently closely located Pogachas. The next day they came over and I showed them the various cool looking things my computer connected to my flat screen TV can do. This includes Vista Media Center showing my photos from recent trips and Google Earth mapping out our respective homes and my recent trips (and Paris). Additionally, we played Wii which, unsurprisingly based on anecdotal evidence from varied sources across the Internet, was a seeming hit. Mom broke records playing bowling with my dad and I, Dad did an excellent job fishing, and Grandma's slow but steady win's the race approach to cow racing worked very well.

The next day I drove them to Seattle and we walked around Pike's Place. My parents made dinner that night at my place which was very good and made my apartment actually smell like cooked food. Also, we exchanged Christmas gifts. For the past two years I've flown back to my parents' house for Christmas and ended up with gifts I couldn't take with me in both directions. Those I left at their house they drove up and I was able to give them the ones I left at my place. They started the drive back the next day. I really enjoyed seeing them here.motorhome family personal nontechnical

San Francisco Trip

2007 May 11, 7:48After Carissa and Elijah's wedding Sarah and I went to San Francisco. We drove in, well Sarah drove anyway, still in the PT Cruiser Sunday morning and checked into our hotel, Hotel Diva. I was originally concerned that I wouldn't fit in as I don't really consider myself a diva, however the hotel was cool. They have Internet rooms setup in various themes, the front desk is always staffed, our room had a very modern look, and when we entered the flat-screen over the front desk was playing an episode of Aqua Teen Hunger Force.

We walked around a bit before going to the SF Museum of Modern Art. There was a Picasso exhibit at the time which we could see for only $3 more. It felt kind of wrong like my ticket was super-sized. I think the most memorable piece I saw was three white panels which consisted of three blank panels. Art. Sure. After that Sarah wanted to see the giant Hello Kitty store she had heard of from her sister. We ended up going to the Westfield Shopping center which has a disappointingly average sized Hello Kitty store. Apparently the giant one is gone. That night we went to First Crush for dinner. I had a flight of wine which consists of three one-third sized glasses of various but complimentary wines. It was a great restaurant in terms of food, drink, atmosphere and service.

The next morning we were even more the tourists when we went down to Fisherman's Wharf and Pier 39. We visited the famous wax museum and purchased multiple pounds of taffy. On the way back to the Oakland airport we got to experience a little traffic as part of the 580 freeway had collapsed the morning we arrived and was still under repair on our way out. We survived of course and I think the trip went rather well.sanfrancisco personal california sfmoma nontechnical

Commenting Wishlist

2007 May 1, 4:33In the past I've come up with ideas for software and find that the very idea is implemented soon after. So this time rather than getting down about it I'm going to make it work for me. I'll state what I want to use and hope that its magically implemented. In order to uniformly support comments on my website I want a web service with the following features:

• Allow users to view and add comments for any particular URI.
• Use OpenID and optionally Card Space to identify users.
• Use a captcha system that's optionally cute or humorous.
• Has atom or rss feeds of the comments available.
• Doesn't require users to register.
• Doesn't require any extra steps for commenting on a URI that no one has commented on.

I'm going implement this now so no one go off and do it before me so that I can use it without having to do anything...technical homepage

Movie Times

2007 May 1, 3:48The Sunday of the weekend before last I had friends over and we watched Antitrust and Sneakers. Watching Antitrust makes me wonder if Bill Gates has seen it. Tim Robbins plays a character that is essentially based on him but so over the top that its ridiculous.

A few days before that I watched The Prestige with Sarah. I can't tell if I was or wasn't supposed to know what was going on until the end but it was cool anyway. I didn't know until later but David Bowie plays Tesla which is just awesome all the way around.

We also watched The Illusionist sometime before. Both movies are adaptations of novels with stage magicians set in turn of the century England. And I enjoyed both of them. I thought one would be a rushed attempt by one studio to compete with the another on the same ground but that doesn't seem to be the case. I've noticed this before with those asteroid disaster movies and the two movies about Truman Capote. It turns out Wikipedia has a huge list of competing similar movies.personal movies nontechnical

Trivia

2007 Apr 21, 11:38This previous Wednesday, I went to trivia at the Wilde Rover. Our team consisted of Sarah, myself, Jane, Eric, Rachel, and Ansen. Before the last round we were 16th (out of ~32) but after the final round we were 6th! The previous time Sarah played there the exact same thing happened. Of course you must be in the top five to win money (or last place who gets their money back). You could say, of those who didn't get any money we did the best! I didn't contribute too much except for spotting a street from Paris in the picture round and knowing which generation the Wii is of Nintendo home consoles. Mostly I focused on increasing our bill =)bar game personal trivia nontechnical

Bunny Weekend

2007 Apr 8, 3:46This weekend was fun. Sarah and I went out for Jane's Birthday. We ate at a little Italian restaurant where our group was almost too large for the place and afterwards went to the Viceroy lounge. The website apparently isn't very representative because although I looked at it before going out and I'd been to the place previously, I didn't realize it was the same location until we got there.

I got several games for my Wii through Sarah's connections including Wii Play and The Legend of Zelda: Twilight Princess. We played both of them and I thought Find Mii was especially fun.

Sarah's bunny is getting pretty big. Its been biting through wires now includig part way through the power cord to the cable box. You'd think after getting to the copper that it would learn to stop. At any rate, it didn't hide any eggs. I don't have any new photos but you can see the old bunny photos via my Vizicious tool.personal nontechnical seatle wii

Delicious shortcut tag

2007 Apr 8, 3:05Shortcut Tag?
I just saw this on another user's delicious links: a link to ESV search that's tagged with, among other things, "shortcut:esv". When viewed on del.icio.us there's a text box that lets you search using that link. I hadn't seen this before, but it seems pretty cool and I'm surprised I hadn't seen it previously. A delicious post with such a tag ends up looking like the following: I tried searching for information on this and I've found other delicious users doing the same thing, but nothing about the tag itself. If you know any information especially official information from del.icio.us itself please post links in reply to this post. So without further preface here's what I've learned about the del.icio.us shortcut tag.

How-to
To get a search box in your del.icio.us links make a post that satisfies the following requirements:

1. One of the tags must begin with the text 'shortcut:'. You can have more text following that in the tag if you like but it must at least start with 'shortcut:'.
2. The 'url' you post must be a shortcut url rather than an actual URL. It must contain a '%s' with a lowercase 's'. When you enter text into the textbox on the del.icio.us page the text will replace the '%s' after being percent-encoded. For example 'http://www.google.com/search?hl=en&q=%s' is the shortcut url for Google and if you type 'foo bar' into the textbox the URI you will navigate to would be 'http://www.google.com/search?hl=en&q=foo%20bar'.

Complaints
This is neat but I do have a few complaints:

1. The text from the textbox is percent-encoded before replacing the '%s'. Most sites use application/x-www-form-urlencoded which encodes spaces as '+' rather than '%20'.
2. The shortcut url format seems to be taken from Mozilla's Firefox Custom Keywords. Its a shame it wasn't based on something more adaptable like the OpenSearch URL template syntax.
3. A '%s' in the url means technically what you're submitting to del.icio.us isn't a URI as defined by the standard.
4. Allowing text after 'shortcut:' means you can't look at all of a user's shortcut using this tag.

The next step is to create a tool to sync my IE7 search providers with my shortcuts saved to delicious...technical howto tagging tool tag delicious

Weekend Humor

2007 Mar 13, 8:16Over the weekend I went with Jon and Sarah to see Zach Galifianakis perform at The Moore who was awesome of course. I hadn't been to The Moore before but it was very cool. The space is very vertical with two levels of balconies making it seem small in the other dimensions. We were on the middle level so when Zach climbed off the stage to talk to the audience we couldn't see him.

Before the show we ate at The Steelhead Diner. I enjoyed my chicken sandwhich but the place seemed a little full of itself with salt and pepper that had been infused with this and that. At any rate it had a nice atmosphere and good food which I suppose is the point.

The opening act for Zach was another comedian whose name I don't recall. He was pretty funny but seemed to do just a tad too much pandering to the Seattle audience. "The administration should do something different than what they're doing currently!" *Audience Cheers* is sort of equivalent to "Its great to be here in... Seattle!" *Audience Cheers*.personal seattle nontechnical

Plane Wackiness

2004 Apr 22, 6:44My interview was scheduled for Monday starting at 8am, so when I signed up for the trip and MS suggested a departure time of 4:30pm on Monday I thought that'd be good. Unfortunately the entire process ended at 4:15pm and it takes a little more than 15 minutes to get from Redmond to Seattle and then through the whole airport deal. So after the taxi ride to the airport and waiting in line for like 20 minutes its 5:30pm and I'm at the front of the line asking this woman for a new ticket.

Woman: *typing* Well I can get you to LA... Me: Yeah well that's the right state. Woman: *still typing* Oh... Hmm... Uhoh... *other non-words* Me: *waiting patiently* ... Woman: Are you ready to run? Here's your ticket. Gate C11.

I look at the ticket and the plane's boarding at, what do you know?, 5:30pm. So yeah I start running. I hit the security check point line and I know all about this. I take off my belt and shoes and empty my pockets into my backpack, my only luggage. I am Mr. Prepared, or maybe Prepared-ness is my middle name, whatever. I get through the line with no problem, put on my backpack and holding my shoes and belt in one hand I notice a big old clock just to my left. While I'm staring at it, it changes from 5:42 to 5:43. "Oh shit!" I think, so I start running again. I finally get to the appropriate gate and get on the plane all out of breath. I'm walking down the aisle with shoes and belt in hand, and I guess I look a bit out of sorts. I sit in my seat and I'm telling the guy next to me about my whole deal: "Ha. Yeah. I was late and with the running and the security checkpoint..." into incoherent mumbling and gesturing. So it turns out the pilot and copilot's incoming flight was way late and I ended up sitting in my seat for another 15 minutes before we could take off. All that wasted running. What a shame. Coming into LA we've been "landing" for like 20 minutes. We finally get on the ground and its 30 minutes passed the boarding time of my connecting flight. I start thinking about anyone I know who lives in LA. All the other passengers stand up and block the aisle. Then, an announcement "Will Daniel Riesney please come to the front of the plane." OK I can tell that's supposed to be my name, but how the hell am I supposed to get to the front of the plane? The people near me who have heard me talking to the guy next to me about this let me past easily enough. But now I have to explain this to each person out of ear shot to further my progress. "Hi. Excuse me. They called me to the front of the plane. Pardon me. Can I get by." And so on. Its getting more hostile the closer I get to first class. Up to this one guy. He's trying to talk on his cell phone but its not working because everybody is trying to talk on their cell phone now that we've landed. His phone connection has failed. I can't guess at what else has happened to him today but he's decided to make his Custerian last stand here between me and the rest of the plane.

Me: *continuing from previous passengers* Excuse me. Pardon me. Guy: *spinning around* WHAT!? Me: Can I please get by? Guy: What? Why? Were not going anywhere! This whole time I've been forcing my way past him. Guy: There OK your past me now! Your several feet ahead of me! Congratulations! Me: Dude, I'm sorry they called me to the front of the plane. Guy: I find that highly unlikely!

Whatever. I keep walking and like 7 people past the asshole I guess the flight attendants give up on me and start letting people off the plane. Now who feels like an asshole? Its me. I get off the plane and some airport guy has a new schedule for me. Oh good I'm thinking, I've got an hour until the next flight's boarding time at 10:30pm. So I get on a tram to travel to the other side of LAX. I wait for oncoming traffic to stop so I can climb up a stopped escalator (Incidentally right next to it is another escalator which has been closed off. Why would they do that? Escalators cannot break they just become stairs.) I get up there and wait in line for an extreeeeme amount of time and finally get up to claim my ticket. Its 10:20. I get my ticket and, yeah, the departure time is 10:30, the boarding time is 10:10. So I start running again. More security check fun. I finally find my boarding gate. I rush up...

Me: *breathing heavy* Here's my ticket Lady: Oh good your finally here. Just go right out that door, *points* down the stairs, *more pointing* and wait for the tram.

WHAT? Isn't there supposed to be a PLANE somewhere? This is what I'm thinking not what I'm saying. So I walk outside and down these steps. And I'm waiting. The lady from inside joins me.

*awkward silence* Lady: The bus should be here pretty soon. Me: So... I'm going to miss my plane huh? Lady: Oh no, see here? *points at my ticket* Your ticket is confirmed so they can't leave without you. Me: Oh good... I hope they didn't tell the other passengers that.

Lets see how many passengers I can piss off in one night. Eventually this bus shows up. I get in and the guy starts driving. "Do you know where I'm going?" I ask. "Yeah" the guy says. Great. Fine. Whatever. I don't care anymore. So we drive back around to the OTHER SIDE of the airport. You know, the side I started on. Yeah that side. So I get off the bus and walk into the small building set aside for smaller airlines. I see the frantic looking ladies manning another of these gates. They see me, check my ID and ticket, and one of them ushers me out the door next to the gate. Out the door and into a small gated area outside. So me and this new lady are just standing here. Even had I the energy to ask her what was going on its very loud what with all the planes. So we just stand here at this gate facing the planes for a while. I look at her trying to make eye contact and get some sort of acknowledgment that we are in fact waiting for SOMETHING. Eventually one of the day-glow guys appears from between some planes and saunters up. The lady hands him a paper and walks away. At the time I was kind of offended but looking back on it, maybe the lady was a deaf mute and I'm the one being insensitive. So now I follow this guy through a bunch of planes. I'm yelling "San Luis Obispo?" trying to be heard over all the ambient noise and this guy is somehow responding to me with an even tone no yelling required. I don't know how he did that. We finally get to the plane and its 10:40. So I delayed the flight ten minutes. I'm thinking its going to be really awkward when I sit down and we immediately leave. Its going to be suspicious even. But, not to worry, we wait while the flight attendant argues with the guy who brought me to the plane for another ten minutes about how many people are supposed to be on the plane. Whatever.
