Two-for Script File

2007 Aug 6, 5:40I was messing with the XSLT to XSL Converter source which is a javascript file that can be run with cscript.exe. I've changed it to be like a very basic version of xsltproc that simply runs an XML file through an XSLT. I also wanted to run this from the command prompt without writing "cscript ..." everytime. I decided to make like perl programmers I've seen and make a JS file that works as a batch file and a JS file at the same time.

Here's a basic version of what I ended doing applied to a 'hello world' script named helloworld.cmd:

/* 2> NUL
@echo off
cscript /e:javascript /nologo "%~f0" %*
@goto :eof

    Hello World
        Says 'Hello world.' when you run it.
*/

var outText = 'Hello world.';
WScript.Echo(outText);

Running this on a command prompt gives the following:

C:\Users\davris>helloworld

C:\Users\davris>/*  2>NUL
Hello world.

However, after a little more experimentation I found this was slightly overkill for my purposes since if I rename the file to helloworld.js and just type its name like a command it is run by cscript:

C:\Users\davris>helloworld
Microsoft (R) Windows Script Host Version 5.7
Copyright (C) Microsoft Corporation. All rights reserved.

Hello world.

So this time I didn't need all that but if ever in the future I need to run a batch file then a JS file I can do it with one file...cmd js technical cscript batch xslt xsl javascript

BBQ x 2

2007 Jun 11, 3:36This past weekend I was invited to two BBQs. Consequently, the weather took a break from the heat to drizzle.

The first was a lunch BBQ in celebration of Sarah's mom getting her Masters degree. Sarah and I went to her sister's house on the East-side where we had traditional foods you might associate with a BBQ including some enjoyable sausage. There was a bit of Wii to be had and Sarah's mom killed at bowling. Sarah seemed a bit dismayed at this. I guess Sarah didn't expect it since she's had more experience compared to her mom who was playing for the first time.

For dinner we drove over to Seattle to have a BBQ at Jeannie's house. Jeannie's family and my family became friends through our church when I was born and Jeannie even babysat me. The second bit about the babysitting is how Jeannie would introduce me at the BBQ. I met her boyfriend who seems like a cool guy. He works for Microsoft as a consultant and has traveled to various countries for his job. Guests had been instructed to bring side dishes and so there was quite a spread which was eclectic as well. We brought red potatoes, humus, and pita bread. As it turns out, one of the other guests had produced humus in bulk as a supplier and apparently had a grudge against the big humus chains. We played it cool and she didn't say anything so we can only assume she didn't know it was us. Jeannie was a great hostess and I had a fun time.bbq washington personal nontechnical

Wiimote wiissues

2007 Jun 7, 5:29The other day I had the best idea for my Wii remote. Clearly I should use it to control the rotation of Tetris pieces in my N-dimensional Tetris game Polytope Tetris. One of the issues I described with Polytope Tetris is user input. Given a Wii remote the user could rotate a piece through 3 dimensions in a manner that's much easier to adjust to than particular keys on the keyboard.

Anyway, I did a little research into how this might work. I knew that the Wii remote used infrared for absolute positioning and Bluetooth for everything else (LEDs, speaker, accels.) I bought a Bluetooth adapter for my PC after realizing that none of my computers had one already. I used GlovePIE to ensure that my Wii remote could connect and successfully communicate with my computer. GlovePIE is actually pretty cool -- it provides a simple script layer over the Wii remote to control things like your mouse.

Since Polytope Tetris is in Java I looked for and found a Java library for operating with the Wii remote and a long forum thread discussing its use. I then read up on Bluetooth in Java. Apparently JSR 82 is the name of the standard that describes the API a Bluetooth stack should expose in Java. That is, to get Bluetooth working in Java one needs an additional package for Java that actually implements the Bluetooth Java API. This package would depend on the system so I suppose I can't fault Sun for not including it... Where to find such a package? I found a comparison list of implementations and tried the ones that support javax.bluetooth. None of them worked for me because none can address USB devices it seems or they cost money and I couldn't get the trial version working. I also tried bluesock (not listed on the previous list) which seemed promising and could produce an address for my Wii remote as a connected device but couldn't use that address.

And I thought that after I found the Wii remote Java library it would be easy... Oh well...java bluetooth wii technical remote jsr82 tetris polytopetetris wiimote

Phishing

2004 Aug 19, 2:52I received an email from verification@citibank.com the other day with the subject "Fraud Check Verification". Or at least that's what someone at the jumphk2.net domain would have me believe. The whole official looking email was very convincing at first glance. There's the Citibank logo image up in the left corner, the reassuring TrustE image in the opposite corner, and just the right amount of legal-ese on the bottom. The text requested me to follow a link in the email to update and verify my information. At closer examination however it becomes apparent that this is a scam. Little things start to catch your eye. The TrustE image is hosted on ebay and the Citibank logo is hosted at 65.108.92.50. Both images one might expect to be hosted on Citibank's site. The link in the email looks like its taking you to https://www.citibank.com/saw-cgi/citibankISAPI.dll?PlaceCCInfo but in fact its taking you to a page hosted at 65.108.92.50 again. The following sentence appears in the email:

If your account information is not updated within 48 hours then your ability to sell or bid on Citibank will become restricted.

Oh shit! My bid on Citibank might not go through! Seriously, they might have gone to a little more effort than just copying and pasting a scam letter meant for EBay. And the number one fact revealing the email for what it is -- I don't have a Citibank account. I had received an email exactly like this several months ago and just deleted it, but for some reason, perhaps I was in a foul mood, I decided to do something this time around. I emailed abuse at my domain, the ISP controlling their IP address, and Citibank. My domain told me there was nothing they could do. Citibank has yet to respond. As for their ISP, the following day I received an email from Leon at Alabanza's Abuse department informing me:

This account has been locked down and is now on schedule for deletion. If we can further assist you please let us know.

Fuck yeah! This was a lot better than anything I had expected. I anticipated no response from any of the letters I sent. The page is gone now. Leon rocks!

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.
