Ask Slashdot: Provisioning Internet For Condo Association?

Cerlyn Get a Bulk Contract and the provider does the work (257 comments)

While the majority of comments so far seem to presume the condo association wants to run their own ISP, there is no reason in most of the United States that they have to do so.

Just like your condo association should be able to get "bulk cable", satellite, or Uverse/FIOS/IPTV service, you can purchase bulk Internet in a similar manner. You can even combined bulk TV, Internet, and/or phone service if you want. Even satellite companies have partners who can take care of Internet service nowadays, or can use Ethernet themselves to distribute TV service to the building.

This offloads all the DMCA, etc. work to the service provider, although there are a few catches. The first is that you are paying for service to all units; if a unit owner does not pay their dues, state laws may prohibit you from cutting off service (and even if you could your contract still might require you to pay for it). The second is that most providers currently hooked to your building presume not everyone in your building is using their service; you will need to make sure they provide you enough bandwidth to cover the increased subscription rate.

The third item is that these tend to be long-term contracts; the longer you commit to, the better the potential discount tends to be. However these contracts also include clauses allowing automatic increases in rates.

I looked into this once for a condo association myself; and while a local survey suggested owners wanted such bulk contracts, when confronted with the financial costs (and our rate of non-payment) they tended not to.

Ask Slashdot: How Is Online Engineering Coursework Viewed By Employers?

Cerlyn Re:Professional Engineer stamp is the way to go. (201 comments)

Disclaimer: For mechanical engineers, I personally think that getting a PE often is a good move.

However since this is Slashdot, I would argue that for computer engineers this is not always true, or at least the easiest thing to do in the United States.

While completing college, I took and passed the Engineering-In-Training state exam for Electrical Engineering. I then worked for several years with various employers, some of which had PE's above or adjacent to me in the hierarchy; others of which did not.

The electrical engineering exam for PEs seems to be bending-over backwards to reverse the small percentage of licensed EE's relative to other disciplines. When I looked into this a year ago it was possible to take a purely computer-oriented exam without a lot of the power, electromagnetics, and other topics. The state certifying board where I currently live seemed more than willing to consider justification statements proving that work I did while not under the supervision of a PE could be credited as work experience.

At the time I also was a member the local NSPE/state society, attending meetings with lots of other PEs, and being flooded with offers of legal and civil engineer training courses.

But I never could get PE certification before my EIT expired. The catch was I could not find enough PEs that would be willing to sign of on me as a personal reference, largely because most felt uncomfortable with their knowledge about what I had done.

And since there are so many exclusions to when you can use the term "Engineer" without a PE in most states, I ran out of PEs to ask.

For Mechanical Engineers getting your PE often can be a good thing. But for Electrical Engineers and Computer Engineers especially it can be a chicken & egg problem.

Ford System Will Warn, Correct Lane-Drifting Drivers

Cerlyn The RISKS Digest covered this in 2006 (469 comments)

I'm surprised that I do not see a link to the RISKS article about how a motorist was trapped in a traffic circle for 14 hours yet.

The technology in the RISKS entry was a bit more advanced (lane occupation detection) than what seems to be described in this article.

(And if someone cannot it figure out from the date, the RISKS entry was an April fool's joke; but a lot of people took it seriously at the time.)

Why Any Competing Whois Registry Model Is Doomed

Cerlyn Article is about IP Address sales, not DNS/WHOIS (63 comments)

I don't think many people are getting the point of this article, although I admit it is a bit confusing. While it is true that the article talks about alternative DNS systems and WHOIS; what Paul really seems concerned about is the part of the WHOIS system used to look up who is currently allowed to use a given IP address range, and is responsible for activity originating from it.

The current authorities which run this part of the WHOIS system have rules and restrictions about how and why IP address blocks on the Internet can be assigned from one party to another. Among the things cited by the article which currently are not permitted are obtaining IP address for perceived future needs when you have not already exhausted what you have, or simply buying IP addresses for no use at all speculating they can be sold for more money later.

Some parties do not like these rules, and want to establish their own system for buying and selling IP addresses which is not subject to the rules currently in place. They could kind-of do this right now, but the transfer of ownership would not be recorded in the old system.

This is potentially a bad thing, as suppose someone attacks you from IP address 1.2.3.4. And for some reason, reverse DNS on that IP address fails to work. If there is more than one system tracking ownership of who currently has the right to use this IP address, how do you find the right administrator to contact? And what if someone updated their contact information or the fact the IP block had been sold in one system, but forgot to do so in another?

RFID Checks Student Attendance in Arizona

Cerlyn May have to do with Student Loans and Refunds (554 comments)

If you have any student loans, universities in the United States are required to report your last date of attendance, if you are attending at least half time or not, and other information to the National Student Loan Data System. This may be an automated way that they are trying to get information for this.

While I imagine universities are not going to rush to using the last date you showed up in class versus the current date for refund and grading (withdrawal with no grade versus withdrawal-failing/withdrawal-pass, etc.), I could easily see universities using this data in the event of a grade dispute or similar issue.

Truth Or Dare — What Is the Best US Cell Company?

Cerlyn Re:T-Mobile, UMA, and $0.10 per minute (395 comments)

A slightly clarification here:

UMA service with T-mobile is basically a way to use 802.11 access points as an alternative "cell phone tower" with T-mobile. Nothing stops you from using a UMA-capable phone with standard GSM cell phone towers (unless you tell the phone not to).

In general, T-mobile bills UMA calls *the same* as calls started on the cell phone network. So if you have a post-paid plan, UMA usage typically comes out of your normal minute bucket(s); if you are using a $0.10/minute pre-paid plan, you pay $0.10/minute (as the previous poster mentioned).

There are NO additional fees required for UMA calling versus GSM calling. Turning on 802.11 support might reduce your phone's battery life between charges though.

That said, there used to be some add-on plans which allowed unlimited UMA-initiated calls for a flat rate. But these no longer seem to be offered. In general, the future of T-Mobile's UMA service is unknown, as it is primarily Blackberry phones that tend to support it.

Security In the Ether

Cerlyn Cloud Computing Security Is Another Name for DRM (93 comments)

While they may sound different, the Cloud Computing security problem seems to be almost identical to any other Digital Rights Management problem. Both are concerned with only exposing what the information owner wants exposed to the underlying hardware/provider/user/etc.

It's just a question of whose "Cloud" you are trying to secure information on, and who the "user" of said information is supposed to be.

Boston University Working On LED Wireless Networks

Cerlyn Re:LED Pay Phone Tap (179 comments)

Having seen devices like these in the past, chances are it is a telecommunications device for the deaf, in this case designed for payphones.

I presume there would have been instructions printed on the front of the device that would go something like this: If a deaf or hard-of-hearing person wants to make a phone call, they insert coins, then dial the number of interest. When they see the light on the other end flashing randomly (i.e. not a ringing or busy signal), they can press a key on the payphone's touch-tone pad a few times to cause a prerecorded voice to announce the TTD's presence.

If the party on the other side starts typing with their own Teletype device, the TTD on the payphone will then open up to reveal its own display and keyboard. The reason it cannot be opened up without hearing a remote TTD first (at least on the units I have seen) is to prevent vandalism on what is obviously an uncommon and slightly expensive piece of equipment.

Frogger Synchronized to Real-Life Traffic

Cerlyn Cerlyn writes  |  more than 2 years ago

Cerlyn (202990) writes "In order to celebrate 30 years of Frogger, Tyler DeAngelo and his friends created a version of Frogger synchronized to actual vehicles on 5th Avenue in New York City.

Unlike a previous dangerous attempt at recreating the game, this version fits safely inside of a Frogger Arcade cabinet, and pictures and videos of the construction of the game are available as well."

Playing a Video Game Marathon for Charity

Cerlyn Cerlyn writes  |  more than 6 years ago

Cerlyn (202990) writes "Members of the LoadingReadyRun comedy group are playing a marathon session of the Desert Bus video game to support the Child's Play charity. Child's Play goal is to provide toys, games, books and cash to a variety of hospitals within the United States as well as abroad.

While this video game marathon may seem straightforward, the goal of Desert Bus is to make a series of eight-hour trips from Tucson, Arizona to Las Vegas, Nevada in real-time without pausing, and the amount of time members of LRR are willing to play the game depends on how much in donations they receive. So far, they have driven the bus for 17 hours, and have another 73 hours paid-in-advance to go..."

Cerlyn (202990) writes "The Kennedy Space Center, where the high-tech Space Shuttle launches and can land, is actually part of a wildlife sanctuary. But in order to deal with the alligators, coyotes, wild boar, and other animals which pose a risk to the space facility, NASA takes an extremely low-tech approach.

The Miami Herald has an article on John Tanner, who has been in charge of trapping wildlife around the Kennedy space center for over 40 years. So whether you have an alligator beneath an ice machine or inside of a missile silo, Tanner's your best bet."
