what. [Nov. 2nd, 2009|01:36 am]

If I were a Springer-Verlag Graduate Text in Mathematics, I would be J.-P. Serre's Linear Representations of Finite Groups.

My creator is a Professor at the College de France. He has previously published a number of books, including Groupes Algebriques et Corps de Classes, Corps Locaux, and Cours d'Arithmetique (A Course in Arithmetic, published by Springer-Verlag as Vol. 7 in the Graduate Texts in Mathematics).

Which Springer GTM would you be? The Springer GTM Test

Kindle Ad [Sep. 18th, 2009|11:11 pm]
While searching Google for "kindle dx firmware", I got this strange sponsored link:

Kindle driver - Official Site
Kindle.Amazon.com Reduced Price - now just $299. Free Shipping! No Fee Wi-Fi.

Check out where the link takes you. And "No Fee Wi-Fi?" Are they planning on rolling out a Wi-Fi version soon?

Also, what? After putting down $489 for an e-book reader, asking 80 cents for the manual is just ridiculous.

LJ's old datacenter... [Jul. 4th, 2009|02:48 am]
... had power problems yet again.

This time, the electrical vault for the building caught fire!

TV and radio stations in the building were affected as well.

ETA: Looks like a backup generator failed as well due to a fried transfer switch.

Quote about Seattle fireworks computers:

"They're not much more sophisticated than an Xbox 360," he says. "All that thing is doing is going through a list of firing commands."

Luuulz!

Wii hacked [Feb. 22nd, 2009|06:23 am]
There's lots to update you all on, but for now, I'll just mention that I hacked my Wii to play homebrew apps. Amusingly enough, hidden in the corrupt Zelda file that pwns the Wii is the following song:

The Twilight Hack Song
----------------------

This was a triumph.
I'm making a note here:
HACKED AGAIN.
It's hard to overstate our satisfaction.

Team Twiizers
We do what we must because we can.
For the good of all of us, except the ones who pirate.
But there's no sense crying over every quick plug.
We just keep on trying while there's still one more bug.
And the homebrew comes back, and we make a neat hack
For the people whose Wiis want new life.

I'm not even angry.
I'm being so sincere right now.
Even though they broke the hack and patched it.
And fixed IOS30.
And broke every fakesigned disc out there.
As they failed it hurt because
They were attacking homebrew!
Now these quick hack fixes have some beautiful holes,
So we found them fast and easily met our goals.
And I'm glad we got burned.
Think of all the things we learned
For the people whose Wiis want new life!

Go ahead and patch it.
I think I'd like to have some fun.
Maybe you'll find an undisclosed bug.
Maybe that huge one.
That was a joke, haha, fat chance!
Anyway, this homebrew's great. It's also legal to use.
Look at me still talking, when there's hacking to do.
It might take three months,
but they'll patch this one too.
I've experiments to run, there's reversing to be done
On the people whose Wiis want new life.

And believe me the Wiis want new life!
I'm busy hacking and they want new life.
I feel FANTASTIC and they'll get new life.
While you're dying they'll still be alive.
And when you're dead they'll still have some life.
STILL ALIVE, still alive

It's comcastic?! [Dec. 25th, 2008|03:30 pm]
I'm at my parents' house and the Internet is acting REALLY strange.

This morning I was getting a bunch of packet loss, less than 1mbps on cable, Comcast's DHCP was being flakey (it wouldn't lease an IP for a while... and when it did, it gave an hour lease), etc. When we finally got back online, things got even weirder. Check out these two traceroutes:Read more...Collapse )

I'm leaving for San Jose tomorrow to attend HotSec and USENIX Security. Anyone in the area want to meet up? I'm mostly free tomorrow.

Sidekick hackin' [Jul. 11th, 2008|09:28 pm]
The 3G iPhone was released today, so what did I do? ... I fixed my Sidekick. :P

A couple of days ago T-Mobile broke it. Their data service doesn't seem to give out DNS server IPs to use, so it defaults to using some really old IPs that don't work.

After lots of fiddling around to figure out exactly what the problem was, I came up with a GIANT hack of solution that gets it back on the network. It basically came down to:
  1. Finding my hacked SDK that lets me access restricted methods and fields.
  2. Decompiling the Sidekick code using jad.
  3. Figuring out how it determined what to connect to (it's not trivial... If you disable the NO_SERVICE_PANEL and service redirector flags, AND set Config._DISPATCHER to null, you can set the hostname manually in the flash).
  4. Changing some "privates" to "publics" in the decompiled java code, and recompile it.
  5. Writing an app that sets the service hostname manually (to 216.220.209.23 instead of disp.prod1.dngr.net) and sets Config._DISPATCHER to null.
  6. Uploading the app to device and running it.
  7. ???
  8. PROFIT!
Of course, my screen cable is still sorta broken, but the lovely cmat will be hooking me up with a handful of SK2s to hack together sometime soon.

iPhone [Jun. 18th, 2008|11:33 pm]
I am really tempted to get an iPhone and build a flip-out keyboard for it. It all depends on how hackable the 3G version is, so we'll see.

New Facebook app idea [Jun. 16th, 2008|03:35 am]
Idea: An application that lets you see if your friends have voted yet, and if not, lets you send them a reminder. Optionally, an "I voted!" badge on your profile or some sort of rewards system.

The data is already public record.

Cool, creepy, or just plain annoying?

Oakland [May. 18th, 2008|03:10 pm]
I didn't end up going to SHDH (I wound up going to an awesome boat party in Seattle instead), but I'm in the bay area now. Alexei and I made a reservation for a bay view room, and I signed a receipt for the bay view rate, but they gave us a shitty hillside room (with a view of their glorious HVAC units, no less, and half the size of the hillside room Tammy got) instead. I went to the front desk to inquire about this, and they gave me attitude! But I persisted, and should be getting a bay view room soon.

ALSO, they have no wifi, and my poor XO laptop doesn't have an Ethernet jack, so Internet access is kinda tricky. I'm in Tammy's room right now mooching off of her 'net connection (Windows Internet Connection Sharing).

We'll see if the Claremont Resort can redeem themselves later.

Attention Bay Area Friends [May. 10th, 2008|09:43 pm]
Are any of you planning on going to the next SuperHappyDevHouse? I'll be in the area from the 18th to the 22nd for the IEEE Symposium on Security and Privacy, but I'm considering going down a day early to go to SHDH. Do you have somewhere I could crash that night? Also, if anyone wants to meet up, I'll probably have some free time down there.

In other news, last night was the ACM's Rage Against the Turing Machine party, which was a blast. The Gates Commons was turned into a dance room, with a fancy light setup and first-year grad Peter Henry DJing. The conference rooms had XBox 360s with Rock Band and Halo 3, and the Jaech Gallery had a bar, a ping pong table, and places to sit. It was preceded by a cocktail party TGIF hosted by the CSE women grad students (featuring some fairly strong punch), and followed by a trip to Shultzy's. I'm slightly over-partied at this point, but it was tons of fun.

A couple of weeks ago, we also won the Pacific Rim Regional Collegiate Cyber Defense Competition. Apparently there will be a documentary about it airing on UWTV next month.

Sidekick update! [Feb. 26th, 2008|02:45 pm]
The RFID tag on it didn't lie -- it was actually in the security lab. tamiaka hid it in one of the drawers so Tracy's assistant could stand on the desk to install the clock.

So yay, I have mobile Interwebs again!

Today's statistics [Feb. 26th, 2008|12:39 am]
Hours at school = 12
Hours of sleep = 3
Sidekicks lost = 1
Amount of research done = 0

Oy. And I still have about an hour of work to do before I can pass out.

YARR [Jan. 24th, 2008|04:38 am]
CPU fan just died in one of my Linux servers. Luckily, I caught it before the CPU melted, but I need to keep the machine down until I get a chance to fix it (which might be somewhat hard to do, since it's part of the heatsink, and the heatsink is for a Slot A CPU). It wouldn't be so bad except that it provides DNS/NAT/etc. services for the LAN (and our domains) and the IRC gateway for my Sidekick. At least we're not running an IRC server on it anymore...

Facebook notifications leaking information [Dec. 5th, 2007|02:46 am]
I just received a month-plus old email from Facebook. I went to check the headers to confirm that yes, it was really stuck in their email queues for that long. But another thing jumped out at me: the IP address of the action originator was also included! Not only that, but the subdomain of the page used to generate the action was also included.

For example, malerin friended me today. The email contained this header:
X-Facebook: from zuckmail ([76.14.62.XX]) 
	by uwaterloo.facebook.com with HTTP (ZuckMail);
(Note: the IP address has been partially scrubbed by me)

Now, he isn't in the uwaterloo network; only two of my friends are. So, I am fairly certain he was looking at one of their profiles when he added me. If I only had one uwaterloo friend, I'd know exactly whose profile he looked at.

While this information isn't exactly a massive invasion of privacy, it does leak more information than is normally available at the web site.

(There are some other interesting parts of the email headers, such as the X-Facebook-Notify field, and the fact that tfbnw.net is mentioned a lot -- short for The Facebook Network?)

The Y2K bug resurfaces [Oct. 1st, 2007|12:50 am]
Yes, it's 2007. Yes, everyone's had over seven years to get this stuff right. And yet, the bugs still persist:



Other people told me they saw it as 2007, so I figured it was some javascript/browser interaction bullshit. A peek at the source code:

	// Y2K Fix by Isaac Powell
	// http://onyx.idbsu.edu/~ipowell
	
	if ((navigator.appName == "Microsoft Internet Explorer") && (year < 2000))
	year="19" + year;
	if (navigator.appName == "Netscape")
	year=1900 + year;

*headdesk* This is why I hate javascript.
