If I every have security or body guards, I know what they will be wearing.

If I every have security or body guards, I know what they will be wearing.

Passwords are tricky things.

On one hand it is often said to have unique, complex passwords for each website and every computer. On the other hand we can only remember so much before resorting to password books, spreadsheets of logins and sticky notes on monitors.

In years of part time computer consulting I have seen a bunch of different ways of approaching the password problem. Some have used the same four letter password for everything, occasionally appending a set of numbers if the site requires 6+ characters and numbers to be involved. Others have small address books with websites listed alphabetically with their logins and unique passwords. And recently I have seen an excel spreadsheet with websites, logins and passwords all neatly typed up with notes.

I have done my best to help secure everyone with decent password practices, or at least those best suited to the individual. For those with short and frequently used passwords I had them create a complex password for critical logins like e-mail and computer accounts. Those with small books are actually doing alright, even if their unique passwords are all one word with a number appended or pre-fixed every now and then. And for the individual with a spreadsheet, I could not stop the practice so I made them used an encrypted disk image to hold the password, encouraging them to store it on a flash drive, along with a printed copy as backup.

The challenge for most people in passwords is creating those that are complex enough yet memorable. I found the best method for people is in taking a phrase they know or like and altering it into something unrecognizable. For example a famous quote:

One day, Sir, you may tax it.

– Michael Farady in response to British Prime Ministers Gladstone’s question, “What good is electricity?”.

Then take a short segment of it, “you may tax it”, which is eleven characters and use that as a basis. Add in capitalization of each word, replace characters with numbers and maybe add a few extra on the end. For bonus points add in non-alphanumeric characters. To show how it looks:

  • youmaytaxit – remove the spaces
  • YouMayTaxIt – capitalize
  • Y0uM4y74xIt – replace letters with numbers
  • Y0uM4y&4x!7 – use the shift key
  • Y0uM4y&4k!7 – replace letters with their phonetic counterpart, or similar looking characters
  • Y0uM4y&4k!767 – add some number (the year Faraday died)

The beginning may still look recognizable but the end looks like random characters. A trick to use is just hold down shift for a particular segment, I find that most passwords become muscle memory so after adding in numbers throw in a shift key to get those odd characters.

Of course some websites don’t like this very much. I recently tried to update all of my credit card passwords only to find my sweet new passwords was not accepted due to some unacceptable characters.

Finally I don’t use the unique password for every site technique. Instead I have a half dozen or so passwords that are used depending on how secure that login needs to be. Internet forums have a simple six character password while banks and sites that store credit card information have longer, more complex passwords. Every now and then I introduce a new password and sort of shift everything down a level.

The best thing to do is practice so that password becomes set in muscle memory. Of course if you have ever have to login used an iPhone then all bets are off.

And what a face he has.

And what a face he has.

Why

So why bother with this Facebook thing? What good can come of it when you have been getting by so far just fine?

  • Establishing new venues of communication for reaching a client base, be it a recently published book or an upcoming art show.
  • Find old friends from high school or college. You may not have thought of them for a while or lost contact over the years.
  • Stay in contact with younger family members. While letters, phone calls and e-mail may work for siblings, other relatives may only communicate through Facebook.
  • Establish a place to share photos between friends, if they are already on Facebook.

Communicating

There are four main methods of talking to other people on Facebook. First I would like to define several areas.

A “Wall” is space in a profile where items are posted such as status updates, photos, links and the like. Your newsfeed is your main Facebook page that shows updates from all of your friends, this is where most people spend their time.

  • Write on a wall. This puts the message on either your own or someone’s else’s profile visible to everyone.
  • Comment on an item. You can add comments to items that put onto someone’s wall such a status update (writing on your own wall) or a posted video.
  • Direct message. This is like Facebook e-mail that can be send to multiple people. It also keeps tracks of conversations between so it appears as a thread.
  • Instant messaging. This is just instant messaging through Facebook’s built in client.

Privacy

Assume everything is available for everyone to read on the entire internet. Even if they say it is not just put up what you would be fine saying or showing to everybody.

At first it was just for University students, and all was good. Then the high schoolers came and there was slight grumbling. And once it was opened to all suddenly those drunken pictures could be seen by coaches, parents and potential employers. While it can’t become available to more people now it is good to keep in mind that everyone can see it.

Profile

I get asked a lot about what information to put into the profile section. And the best advice is whatever you want. You can a wealth of information on your favorite books and quotes or leave it blank since you see this is a communication tool. It depends on your goals for Facebook.

On Friends

Some people collect them, others horde a select few. You don’t have to add everyone who asks since some may be random (from collectors) and others you may just not like.

To add friends either search for them by name or e-mail. You can also have Facebook go through your address book to check for people already on Facebook. Or just wait for people to come to you.

As for removing friends, the option is at the bottom of the left column of their profile page. When you do this they are not informed and they can only find out by seeing that you don’t show up on their friends list.

Building software is not that relaxing.

Building software is not that relaxing.

 

I need a good CAD program on my mac laptop (Powerbook so no Windows emulation) and I have found my choices quite limited. As a student I want something free, legally free. Not due to not wanting to pirate software, rather there is not much software our there to pirate for what I am looking for.

Taking the advice of a TA I looked into the QCad community edition. The company releases their CAD software commercially with the binaries released under GPL. I like free open source software when available so I thought I would try it out.

I needed to build it myself, I have never done this before. I turned to my good friend Google and found this post. This gave rough instructions on how to do it and assumed a much deeper knowledge of the process then I had. I was starting from scratch. Here is what I did:

  1. I already had XCode and X11 installed on my computer from a while back so I did not need to install them. They can either be installed from the system install disks or downloaded from Apple (XCode at least).
  2. Next I downloaded and installed fink. fink is a program/terminal command that allows for easy acquisition and installation of packages.
  3. With fink I installed qt3mac by using the terminal command “fink install qt3mac” followed by the supplementary packages qt3mac-shlibs, qt3mac-apps and qt3mac-doc. These are installed by adding the “-shlibs” onto the fink install command.
  4. Next I used cd to go to the directly with QCad in it (the one that was downloaded) and set the path to qt3mac by using the command “export QMAKE=/sw/share/qt3mac” and “export QMAKESPEC=/sw/share/mkspecs/macx-g++”. This sets the correct paths for the build command of QCad.
  5. At this point I realized that I did not actually have gcc installed, I reinstalled it using the XCode installer. gcc is a C++ compiler or a collection of compilers. I think at least.
  6. There site I originally found has instructions regarding a patch but I could not figure out how to get it to work. So I skipped this.
  7. cd to the qcad directory /scripts/ and enter “./build_qcad.sh”. This will start the build of the program which should result in a nice QCad.app program to drop into your applications folder.

For me building the program failed. I think I needed the patch but since I could not apply it (alright I don’t know how) it failed. While doing all of this I found a pre-packaged version of QCad on this nice website. I think I also saw an intel version floating around somewhere, don’t know where I saw it though.

So none of this had to be done if I had just found this pre-compiled version first.

Ironically I finally opened up QCad to find out that it does not do what I need it to do.

I have installed Vectorworks 2009 instead with a student license and will try that out now. I could just break down and go use SolidWorks at one of the computer labs on campus, I just want to have a copy for me to use.

Congratulations to the JPL team for five years on Mars with Opportunity today.

Congratulations to the JPL team for five years on Mars with Opportunity today.

After finishing it all it may be wise to consider options if there are no acceptance letters waiting. 

Here is a list of ideas that I have gathered from what my friends (physics majors) are considering or what I have considered as an alternative:

Teach for America

I applied for Teach for America and got in, but when I received my first acceptance I weighed the options and my dedication to each one and withdrew my Teach for America application. I was excited to do it but I feel that graduate school is a better choice for me right now.

Teach Abroad (I wanted to do Japan)

I wanted to teach in Japan. Actual any excuse that would allow me to live in Japan for a year would have been awesome.

Travel for a year

Taking a year off to travel as a gap year seems like another viable option. It would be a definite breather before plunging into graduate school.

Get a non-academic job

I did not want to get an actual job, several of my friends (in physics) however want to make this thing called “money”. Some of the things I have heard being considered:

  • Engineering job
  • Weapons research
  • Nuclear Technician for the Navy
  • Pilot in the Air Force
  • Product testing for a Telecom company

The best thing to do for this is to go to a Science and Technology Career fair, especially since these jobs will be geared towards jobs in the local area. Unless of course you don’t want to stay in the area. For the jobs as engineers it depends on what type of background you have in physics, for me I have had a good course in Electronics and have also learned how to do accurate machining in a machine shop. I would probably apply to be an electrical engineer if was to choose. 

After any one of these there is always the option to re-apply to graduate school or defer acceptance to follow a particular dream (like living in Japan). Of course there are innumerable options out there.

\Now to wait for the machinations of graduate committees.

Now to wait for the machinations of graduate committees.

With the online application complete, letters of recommendation secure and the personal statements done there is not much left to do. With the online application submitted a period of worry can start over whether documents like GRE test scores, official transcripts and letters of recommendation actually made it to the universities.

So far the universities with an online letter of recommendation system are not able to process letters mailed in and check them off on the online application. For one they said that the application was complete even though the listed a letter as missing. When in doubt you can e-mail the department but keep in mind that they have mountains of paperwork and sorting to do what with all of the stuff coming in.

To keep myself sane (an important thing to do) I made another list. If you cannot tell I am a fan of lists, especially in this process. I altered my previous school list with just the non-applications tasks I had remaining such as registering and uploading secondary information to asking about transcripts.

Just make sure everything arrives by the due date, my challenge was in the letters of recommendation. When everything was in relax there is nothing else you can do. At this point it might be wise to make sure that you are scheduled to graduate on time.

Personal statements are the only thing fully in our control.

Personal statements are the only thing fully in our control.

Personal statements are hard. Hard to start, hard to write and hard to finish.

They feel like the most important part of an application and at the point of writing they are. Though not because they can influence an application completely, rather it is because it is the last and only thing wholly in our control in the later stages of an application.

GPA is set, letters are written and test scores are in. The only major aspect that can be changed is the personal statement. And so it feels so vital to the process.

I did a lot of pre-writing for my statement. I did several rounds of brainstorming, a couple outlines at least two false starts. Eventually I just gave in, sat down and wrote until I could think of no more. I wrote stream of consciousness with notes interjected into the writing and bracketed phrases that needed to be changed depending on the school. Once finished with this free write I went back and color coded comments according to if they are for editing, adding more in or just venting.

It sat on my desktop for a day before I went at it again. I kept every version I made just so I did not lose anything and so I could see how it evolved if I ever looked back at it. With a decent draft done I sent it off to two people who I trusted to edit it (both recently attained masters degrees in English related subjects) and give general advice.

My first draft was written on November 16th and the final version for all of the schools were finished December 9th. I have written previously about my experience writing the personal statement, mostly while I was in the depths of it.

One thing I found lacking on the internet was a personal statement for physics graduate school, so I am posting the general template I used for each school. I do this as a reference and I ask that no one copy it or plagiarize it in any way. Keep in mind that those reading these are not staff members but physics professors, who I would say are fairly smart people. And if someone can find this to copy so can they. For this draft I left blocks of text blank with [University] or [Professor], I filled these in with what I learned by talking to the professors, not just off the websites.

It is the intellectual challenge that drew me into science, the challenge of walking to the edge of the known and searching for the next step. I found this pursuit before my years at university through books such as Michio Kaku’s Hyperspace and Stephen Hawking’s The Universe in a Nutshell. These authors gave me an idea of how to think about the world as a physicist and what it could mean. When I read their words I did not know about the mathematical formalism behind the theories or even the idea such formalism existed. However, I did know that I wanted to study physics and enhance the knowledge of humanity. This aspiration has led me to apply to the [Department] at [University].

While many of my peers were beginning research positions with professors, I spent my junior year at Edinburgh University studying Astrophysics.

At Edinburgh my particle physics professor encouraged me to go to CERN’s last public open day. At CERN I found the work and challenges of the Compact Linear Collider completely fascinating. The guide gave a brief rundown of their current challenge involving the large electric field of the beam breaking down the walls of the waveguides. While she explained, I experienced a direct connection between classroom theory and a real problem faced by an experimental scientist. 

It was the combination of my trip to CERN and my year of astrophysics courses that led me to the fields of space and solar physics. I enjoyed learning about stellar structure and evolution in my courses and the experimental aspect of plasma and high-energy physics at CERN demonstrated to me what can be done in a research setting. Most of my exposure to these fields has come from reading professors’ research and attending various colloquia at my university.

While I work on my research doctorate in space physics I am interested in pursuing research similar to [research] by [Professor]. My goal is to work on space related instruments and technology as well as focus on research that will aid in furthering the exploration and achievements outside of our own world. Research in space and solar science can help me pursue my goals.

I feel the most important class I took to prepare me for advanced research was my second year physics honor’s lab taught by [Professor]. This was a yearlong class designed to introduce how to conduct research. In the first quarter I was given a seemingly simple experiment, such as finding a relation between the size of a capillary and its rate of flow. There were no lab manuals or instructions, and while I was given help by the professor, every step had to be my own. The second quarter of the course was dedicated to two skills: learning LabView in order to regulate the temperature of a copper bar and learning how to fabricate parts in the department’s machine shop. In the final quarter the class collaborated on building a piece of equipment for another professor. For this I learned basic drafting, CAD software, realistic design and how to work with a group on a project.

During my time abroad I applied for several summer REU programs so I could do some real research. Unfortunately, most of the programs were too impacted and I was unable to research over the summer. At the start of this year I contacted and joined [Professor] in his Experimental Cosmology group here at UCSB. I am currently working on two projects, the first is a cryogenic heat pipe and the second is using a micron bolometer for atmospheric modeling. The goal of the heat pipe project is to create an efficient cooling system for the next balloon borne instrument, the COsmic Foreground Explorer (COFE) that the lab will launch sometime next year. For the micron bolometer, I am currently designing and building an enclosure for long term outdoor use. The goal is to predict cloud formation to facilitate several of the telescopes operated by the group in the Sierra Nevada Mountains. 

I realize I have only begun what will become a lifetime of research and discovery, and to that end I am applying to the [University]. I feel that my skills and curiosity will be a match for the program at your university. I am looked forward to participating in the research opportunities offered by the [University] specifically in [research topics]. Along with the research being done by [Professor], I am also interested in the research on [research topic 2] being done by [Professor]. My background in astrophysics and my work with [Professor] has readied me for this kind of research and participation. I consider acceptance to the graduate program at the [University] one of the best opportunities I will have to pursue my research interests will lead to an even better understanding of how the world works. 

Since this is a personal statement most of this will only apply to me but I hope that the general structure and topics will help others writing their own personal statement.

The online portion is fairly repetitive.

The online portion is fairly repetitive.

In conjunction with starting to contact school I also started with the only applications. For the most part the applications are fairly standard asking for contact info, GPA and sometimes deomographic information. Like all parts of the process it is really important to simply keep track of everything.

I listed every school with important information such as:

  • Link to online application
  • Login and Password
  • Due date
  • Unfinished sections of online application
  • Non-online documents required

While normally it is not a good idea to write down passwords I did it for the school since each one had a different requirement, some needed non alpha-numeric characters others required longer length. It is just easier to copy and paste, especially when you have an assigned username.Make a quick reference list of commonly asked information

When pulling out information from an application the required documents are either listed on the application or on the page linking to it. In some cases it is done either on the departmental website or that of the graduate school itself. I know that some of my school provided handy checklists while others sort of buried the information in odd corners.

Early on look for the requirements for the personal statement such as topic, length and formatting. I thought I was done with my personal statements and then I reread the prompt that actually required two separate essays, if I had waited until the last day to turn it in it would have been bad.

A surprise was the requirement of a resumé on a few applications. I had a resumé already made but a full year out of date, it was also written towards getting my a desk job instead of a graduate position. So this had to be rewritten and refocused to a research position highlighting independence, practical skills (machine shop, computers) and ability to overcome challenges. The resumé should complement the personal statement but not repeat material extensively.

Creating an easy reference of the following helps expedite the filling out of numerous forms:

  • Graduate date (estimate it)
  • Physics GPA
  • Overall GPA
  • Last 2-years GPA
  • GRE Scores with percentile
  • Recommender names, positions and contact information
  • For calculating GPA I used my schools GPA Calculator (written for the quarter system).

Do the online applications a little at a time and as a way to take a break from personal statements and GRE study while still progressing forward. Also start to brace yourself for the fees that come due at the end of the application.
