Reflection on Today

It's been four years. It's a beautiful day, and I have just finished the last class* that I will take as an undergraduate student. Kind of a scary thought, in many ways. In the fall, I will start medical school, the next phase of my life. There are still a few months before I do that, however.

In other news today, I had my first opportunity to see the new world-class facilities to go with the world-class doctors that make up the Johns Hopkins Hospital:

The main public areas are beautiful and might be what someone already expects when they think of a top-notch hospital, but rest assured that this is brand new. Hopefully all of the improvements for patients designed into the facility are already being realized.

A nice anecdote I heard today while observing a surgery involved the old operating rooms at Hopkins, now no longer in use (I don't know what the future plans for them are):
  • The old ORs had been in operation for 110 years (granted they've been upgraded and renovated over the years).
  • The first and last scheduled (i.e. non-emergency) operation to be performed in the OR suite was a shunt revision.
All in all, a good day.

*That last class happened to be 520.222 Computer Architecture with Prof. Jenkins; I have to say that this has been one of my favorite classes and professors during my time at Hopkins and I would highly recommend anyone with an inclination toward CS/EE/ComputerE consider taking this class as an elective. The material is very interesting, and yet sufficiently challenging without being overwhelming (though some may disagree with my evaluation). Update 5/8: See also this Washington post article on the new Hopkins building.

Articles on Medicine...and One on Amtrak (Mar 2012)

It has been awhile since I link-blogged, but I think I have a few interesting ones lined up, so here goes:

A few months ago, Wired published a nice long article looking at science, correlation, and causality. It uses the failure of the drug torcetrapib as a lead-in example, and also discusses some interesting stuff on diagnosing back pain. Read here.

The NYU School of Medicine has begun to supplement its anatomy classes with computer simulations. The future is here. It won't replace traditional dissection labs completely, but has a lot of potential to enhance medical education. (New York Times)

Biomedical engineering? How about an artificial heart that doesn't beat? The amazing story here, courtesy of Popular Science.

Now that you're all read out, consider taking some real time off from the world. This Washington Post columnist writes about her experience on a cross-country Amtrak trip, where the destination was the journey.

Verizon Wi-Fi for All Devices: Mac, Linux, Blackberry, iPhone, Android, and more

See bottom of post for minor UPDATE 2/5/2012.

Two and a half years ago, Verizon announced a partnership with Boingo to offer free wi-fi to its FiOS and DSL (3 Mbps or higher only) customers. Although it was a welcome addition, especially because of Boingo's coverage in airports, it was criticized for only supporting Windows devices, while everyone else was left out in the cold. The initial version of the software also had issues installing with the Firefox web browser. I had tried to install the software about a year or two ago and had not been successful, but today I am happy to report that the service actually works much better than expected.

The first piece of good news is for Windows users: Verizon has updated its software so that it is no longer browser dependent to install. You can do so by going to http://www.verizon.net/wifi/.

The second piece of good news is arguably the bigger one of the two. When you go to get set up Verizon Wi-Fi, you will be asked to create a username and password to use with the service. You are then asked to download the software. However, you don't actually need the software, although it makes the Wi-Fi much easier to use on Windows. For all other platforms, you can simply use Boingo's web login page. Yes, that's right. Remember that username and password you created? After you connect to the Boingo wireless network and get to the Boingo splash page in your browser, click on the dropdown that says "Roaming Login". Choose "Verizon Business" and enter the username and password that you set up earlier. You need to include "@verizon.net" as part of the username. This means that any device with a web browser can now use "Verizon Wi-Fi" where there is a Boingo hotspot! The fact that Verizon doesn't report this method seems to be a large oversight on their part. Or perhaps they want to keep the number of Wi-Fi users down because the more users that use the service, the more they have to pay Boingo.

It is possible you will not be allowed to register for the service at http://www.verizon.net/wifi/. without being on a Windows machine, but such a restriction, if it exists, is minor compared to not being able to receive the service at all, and is easily worked around by tech savvy users. It is also possible that this capability to login with just a username and password was only added recently. Nevertheless, it is extremely useful and I hope that other people will benefit from this knowledge, which I have not seen reported elsewhere online.
Note: Boingo's website may show more hotspots than Verizon's list, but that is because Boingo users are allowed access to some partner hotspots, while Verizon users cannot access those hotspots (you might be my friend, but your friend is not necessarily my friend too). However, this also theoretically means Verizon users can access non-Boingo international hotspots that also list "Verizon Business".

Minor Update 2/5/2012: It appears that not all Verizon Wi-Fi listed hotspots can necessarily be used as described in my post. I've discovered that the Marriott Long Island "ibahn" SSID doesn't seem to have Verizon listed as a roaming provider, even though the Windows app can log on. Go figure.

Chase Credit Cards and Credit Reports

Good news for many Chase credit card holders!

Many Chase credit cards are popular because of the rewards programs and sign on bonuses associated with them. However, many of those cards feature a "No Preset Spending Limit" (NPSL) feature. Chase used to not report the credit limit on those cards to credit agencies, which could lead to a poor credit score because of a high credit utilization ratio (statement balance divided by available credit). I recently decided to contact them to see if they would consider reporting the limits and was pleased to find out that starting this month (November 2011), and because of customer requests, NPSL cards' credit limits will now be reported. I was able to verify that this is the case via creditkarma.com's free credit monitoring service.

On the Interview Trail: Transportation in the Northeast

First, a little background for those unfamiliar with the medical school application process: students preparing to enter medical school the fall after they graduate from college, like me, take the MCAT anytime from the summer before junior year to the summer after junior year of college. Then, during the summer of their junior year, they submit their AMCAS application, a sort of common application for most medical schools in the United States. Once the AMCAS has been submitted, secondary applications which provide supplemental information specific to each school are submitted. After schools review both the content of the AMCAS and secondary application, they decide whether or not to offer a personal interview to the applicant. The interview always comes before an acceptance; no applicant is accepted without one. Interviews are usually held from fall through March.

I have been to a few interviews, but the most time consuming aspect of interviewing is traveling to and from the interview. I don't have a car, so I opted to take public transportation. Here, I'll just address the options as they apply to the Northeast (i.e. DC to Boston). My options have been plane, train (Amtrak), and bus (BoltBus, Megabus, Greyhound, etc.).


After having experienced both trains and buses so far, I have to admit that Amtrak is my preferred way to travel. At least up to New York, it is faster than a plane when you consider security and check-in times, as well as accessibility (Baltimore Penn Station is much closer to Hopkins than BWI Airport). Also, Amtrak ticketing is much more flexible; should plans change last minute, you can cancel any unprinted ticket and receive a full refund. Try that with a plane ticket, which is more expensive to start with.


While the BoltBus has WiFi and is cheaper than Amtrak, it is noticeably more cramped. Amtrak has wide seats and a lot of legroom, and very large overhead compartments (most suitcases that you would have to check on an airplane can even fit up there). Amtrak also has food for purchase onboard, and a tray table on which you can eat either the onboard food or food you bring on the train. Plus it is a handy place to put your laptop compared to your lap. Amtrak also has plans to put WiFi on all of its Northeast Regional trains in the future (currently it is only on Acela trains and in major stations in the Northeast Corridor).

The other main disadvantage of the BoltBus is that it takes longer than Amtrak and is subject to traffic conditions on I-95. All that said, the advantages of Amtrak seem to outweigh the higher cost of the ticket. Of course that may not be true for everyone, but I wager that for most people, $30 or so would be worth the upgrade from a bus to Amtrak.

The one case in which I could see using the plane would be for a trip up to Boston. Boston is far enough from DC/Baltimore that a train or bus affair ends up taking a good part of the day. However, if this country invests in high speed rail infrastructure, then that trip would also be competitive by train, though not any time in the near future because of how long that infrastructure would take to develop.

Anyways, that was a fairly long and rambling post. In short, don't forget about Amtrak the next time you travel in the Northeast.

Footnote: I strongly believe our country should invest in high-speed rail. If you look carefully, the opponents of such investment usually have a vested interest in the automobile, petroleum, or airline industries. As far as those that complain about the amount of money the federal government throws at Amtrak, consider that the interstate system is also largely funded by the federal government.

Patients or Cases?

I'm glad to see that medical schools are incorporating activities to reinforce the human side of medicine, which, in today's rushed pace, is sometimes forgotten.

NextBus GPS Tracking for Johns Hopkins Transportation

The NextBus service is now used to track:
  • Blue Jay Shuttle

  • Homewood-Peabody-JHMI shuttle (aka "JHMI shuttle")

  • Keswick-Homewood-Eastern-JHMI shuttle

  • Homewood-Mt. Washington shuttle

The NextBus website includes a map that shows real-time locations of shuttles overlaid on a street map.

To obtain an estimated arrival time, you can:
  • Visit the NextBus website

  • Call (410) 834-2833 and enter your stop number.

  • Send a text to 41411 with "hopkins 123" where 123 is the stop number.

Stop numbers are posted at each stop and can also be looked up by Route/Direction/Stop on the NextBus website.

Johns Hopkins Blue Jay Shuttle

For the most current information on the Blue Jay Shuttle, including a map of the routes and list of the stops, visit the JHU Parking and Transportation webpage. At the time of this post, the only way to view individual route paths is through the NextBus interactive GPS map (click on "Select Routes...").

Here is a one page reference listing all the routes and stops with their NextBus numbers, as well as hints as to where each stop is found without a route map. (This is an unofficial document that I made, and there are no guarantees made as to the accuracy of the information.)

The JHU Gazette has also published an informative article on the new service, available online.

Blue Jay Shuttle stop sign

Hopkins has posted information on the new routes of the Blue Jay Shuttle (which replaces the old Security Escort Van service), effective August 24th. In summary:
  • 5:45pm-11:15pm: There are 5 fixed routes (Red, Blue, Green, Orange, Pink/Purple) that depart every 30 minutes from Mason Hall with the first departure at 5:45pm and last departure at 10:45pm. Although the Gazette reported that there would be 10 vans running the routes, it currently (8/23) appears that each route will be run by only one van, each of which takes about 20-25 minutes to drive the full loop. One van alternates departures along the Pink (:15) and Purple (:45) routes, so each of those routes only has hourly service. Shuttles operate daily, excluding holidays. All shuttle stops will be marked with a sign. No schedule for specific stops is available at the time of this post.

  • 11:15pm-2:00am: Call (410) 516-8700. All vans operate point-to-point service. An estimated pickup time will be provided.

  • 2:00am-4:00am: The same service as from 11:15pm-2:00am, but fewer vans will operate.

Pro tips:
  • To board anywhere other than Mason: flag van with a J-Card.

  • To drop-off anywhere other than Mason: tell the driver when approaching the stop.

  • Vans only stop at designated stops, except for emergencies or disabilities. According to the Gazette article, students can request a ride to Mason Hall or the nearest stop if they would need to walk more than a few blocks to their destination.

NextBus has also been deployed with the Blue Jay Shuttle. See my other post for details.

Updated 8/23/2011 9:48pm with information regarding Pink/Purple.
