I’ve been lazy and didn’t feel like updating it till someone started asking me for more info.

ITS’ quota page

Network bandwidth is a limited shared resource constrained by cost.

Heavy use by a few users can affect service for everyone.

In an effort to maintain these resources and meet all needs, a throttling system has been put in place by ITS.

Limits are not enforced by application or content (there is no distinction between web browsing and gaming) but rather by identifying users who are found using disproportionally large amount on a daily basis.

Typically, less than 2.0% of active users are throttled at any given time.

Network hosts exceeding the daily transfer quota of 2.0 GB will become bandwidth restricted (throttled) with regard to the Internet until 5:30 AM the following morning. If throttled after 12:00 AM, the restriction will remain in effect until the next day.

Those that are throttled 3 times in 7 days will continue to be throttled for 3 days thereafter.

The current throttled restriction is a connection speed of 2.0 Mbps.

The page is slow to update based on packet flow polling intervals so you might be capped even if it says you’re aren’t.

Also, “tempest” at this time is NOT CAPPED/Throttled. My guess would be that they assign IPs dynamically and don’t have an easy way to impose caps but I’m sure it’ll be coming sometime in the future.

One more correction:
- There is no 6 gig cap. If you hit the cap three times, you’re throttled for days. (eg. 6 gigs in one day).

My life just went to hell. ITS, formally UNET has decided to start imposing bandwidth caps and then throttling.

This is what I’ve gathered (so far):

• This applied to “tempest” & the dorm network




• If a user downloads/uploads 2.0 gigabytes per 24 hour period, the user is throttled at 2 megabits/sec until 5:30 AM the next morning.




• If a user downloads/upload more than 6.0 gigabytes in a 7 period the user is throttled at 2 megabits/sec for 3 days.




• After coming out of a 3 day cap, you hit the following limits from above you get throttled again at 2megabits/sec




• LAN traffic is not throttled




• Akamai traffic is not throttled

I’ve been throttled twice so far and I’ve yet to get an e-mail or notification that this is going on so as of now these caps are ‘hidden.’ I’ve also had problems with certain files/protocols (eg. downloading a podcast that an mp3 over http) that displays behavior of being packet shaped.

I’ll update when I get more info. ITS, if you want to contact me and correct me, feel free to do so.

So I came across this page today that lets you control X-MAS lights via a webpage. I got the urge to see what I could do.

So I wrote a bunch of curl statements that let you submit the post via curl so you can submit via bash.
Lights On:
curl -d “Nb_var00=1&press=Do%20it!” http://uatree.0×58.com/submitted.html
Lights Off:
curl -d “Nb_var00=0&press=Do%20it!” http://uatree.0×58.com/submitted.html
Scroll Lights:
curl -d “Nb_var00=2&press=Do%20it!” http://uatree.0×58.com/submitted.html

Then, I wrote a bash script to always make sure the lights are off.
#!/bin/bash
while true; do
curl -d “Nb_var00=0&press=Do%20it!” http://uatree.0×58.com/submitted.html
echo lights out!
done

hehehe

Pretty interesitng hearings, this is going to be an issue pretty soon. I really hope the Government can get a technical panel or something, it’s almost as if they don’t have a grasp of exactly what is going on. Ask for specs on what Cisco is selling please, it will settle it.

Over the past few days I’ve had to explain a few things to lots of people which gets kind of annoying so I figured I’d just make a post out of it and point them to the website.

COS 125:
Problem 1:
In this problem you can’t simply divide like (/ 2 4) Why? If you divide it will output as one element, the question asks you to output it as two elements, a numerator and denominator.
You then display it as this small chunk of code:
(display numerator)
(display “/”)
(display denominator)

An example of this is posted here > COS 125 - RatNum.scm

You might be asking yourself how do I output two values? The answer it the “gcd” operator. This finds the greatest common divisor you should then be able to figure it out from there.
Public Speaking - Persuasive #2:
8-9 minutes with 30 second bumpers.
Two preparation outlines, full text in outline form.
Problem solution format (pg. 404)
Two points of refutation (mark them)
Must have visual aid.
5 source min, can be the same sources as Persuasive #1

Anything else I forgot? Feel free to post a comment.

I will be bringing the webcam back later tonight. I will also see if I can get Jeff to give me a copy of his Mobile Blog Script so I can post pictures from my phone. i am taking at least three a day that I think about posting but it isn’t worth a whole entry.

I’d love to actually work on it too but I have no idea how much time I will have. College tends to find ways to keep you busy.

We’ve spent about 4 hours on this problem but I think we finally got it! Stupid proofs, for those who might actually understand this stuff, we’re optimizing logic gates.

Anyway, here are the picks.

Papers and papers of proofs

Google hasn’t even opened it up to other Jabber servers, for example if you signup at jabber.org and try to contact someone at talk.google.com it blocks you. The same thing also applies to someone from talk.google.com contacting jabber.org.

According to this article during the launch of Discovery the shuttle hit a bird.

“Without ever having seen these camera angles before, they don’t know if debris has always shed off or if they had hit birds in the past.“

Planes have been known to have trouble with birds, never heard of space shuttles.
