College Textbook Lifehacks

Python as a first language: a roadmap to getting started.

I personally prefer Java as a first language. Put non-technically, it is a lot less convenient, so you get a more realistic idea of how computers work. Nonetheless, Python is an amazing language (with convenience as one of it’s values) so it makes sense as a gentle introduction. It’s also a popular language for data science and machine learning, so it’s great to have experience with.

The 3 ingredients you need to get started:

The Python Language Interpreter: when you write some code in a text file and save it as a .py file, the Python interpreter is what turns that code into commands that your computer can then actually preform. This is necessary.

An Integrated Development Environment (IDE): An IDE is like a helpful text editor for programming. Some basic features include auto-complete, typo and mistake catching, and automatic text coloring to make some parts of your code easier to find. This is optional but highly recommended.

Some learning resources: We’re going to need something about programming basics, problem solving in computer science, using an API, learning how to use google and stackexchange, data types, control structures, and then maybe an object-oriented programming intro, and eventually all the neat advanced features of the python language. Then we need to learn how to use Numpy (for scientific computing), Pandas (for easy data storage), and Tensorflow (machine learning!). Add some handy cheat-sheets for python, numpy, pandas, and Tensorflow, and we’re good to go.

Other posts will adress download, installation, and resources.

A curriculum:

Like I said up above, we need to know how to do the following. Save this and make it a checklist.

Learn to use google to answer questions about installing or using python, any packages, or computer science.

This also includes getting to know how to search Stackexchange, the website for coding questions n’ stuff.

How to install python 3 and get set up

How to install an IDE like Eclipse (with PyDev), IDLE, or Notebook++.

Programming basics: how does python work? What does the language look like? How does tabbing work?

Understand basic logic, including AND, OR, XOR, NOR, NAND, XNOR, Implies, and If…Else statements.

Variables: what are they, how do I set one and change it?

Basic math in Python.

Data types: what kinds of variables can I have? How does my computer store data? How do I use those types of data? What are the key commands and operations I know how to do?

Control structures: if, else, elif, for loops, while loops, break, continue

Methods! What are they, how do I make one, what can I do with it?

The open() command, the all() command, other neat built-in methods

<function name>= lambda <your variables>: <single line method>

Problem solving in computer science: now do fizbuzz.

What’s a package?

Importing packages, installing packages you don’t have with PIP

Using an API: how do I find one and how do I read it?

object-oriented programming in Python: what’s a class, how do I make one, how do I reference and instantiate one, methods, class vars, etc

Error handling: how to do exceptions

All the neat advanced features of the python language: iterators, generators, list comprehensions, enumerate, range, assert, with…as, etc.

Read through the Numpy API (for scientific computing), data types, matrices, stats, methods, etc. A short detour through scikit would be helpful.

Read through Matplotlib.pyplot API, plotting, plotting options, histograms, scatterplots, etc.

Pandas (for easy data storage), data frames, series, built-in operations on columns and rows, loading from a CSV, saving as a csv, apply, etc

Tensorflow (machine learning!) For basic stuff, shoot for knowing how to use the estimator package, which is discussed elsewhere on this blog. Also get to know the nitty gritty, including tensors, layers, tensorboard, etc.

To all my freshman babies who are panicking right now about how much your college textbooks cost: Yeah, you’re right, that’s some highway robbery. No, you don’t have to lie down and take it. You have options. Follow my advice and fly on your own debt free wings.

1. Forgoe the bookstore entirely. Sometimes you can get a good deal on something, usually a rental, but it’s usually going to be considerably more expensive to go through official channels. Outsmart them, babies.

2. Does your syllabus call for edition eight? Get edition seven. Old editions are considered worthless in the buyback trades, so they sell for dirt cheap, no matter how new they are. It’s a gamble, sure; there might be something in edition eight you desperately need, but that never happened to me. However, I’ve only ever pulled this stunt for literature/mass comm/religious studies books, so I don’t know it would work in the sciences.

3. Thriftbooks.com, especially for nonfiction and fiction. Books are usually four or five dollars unless they’re really new, and shipping is 99 cents unless you buy over 10$ in books, in which case shipping is free. 

4. Bigwords.com. It will scan every textbook seller on the internet for the lowest price available, and will do the same to find the highest price when you try to sell your books back at the end of term. Timesaver, lifesaver.

5. In all probability, your library offers a service called interlibrary loan which is included in your tuition. This means if your library doesn’t carry a book you can order it for free from any library nationwide in your library’s network and it will be shipped to you in a number of days. Ask a librarian to show you how to search for materials at your library as well as though interlibrary loan; you’ll need to master this skill soon anyway.  If you get lucky you can just have your required reading shipped to you a week before you need to start reading, then renew vigorously until you no longer need to item. I’m saving over 100$ on a History of Islam class this way.

You professors might side-eye you for bringing an old edition or a library copy, but you just smile right back honey, because you can pay your rent and go clubbing this month. You came here to win. So go forth and slay.

How to Read From a Textbook

Hi guys! So I’ve noticed that a lot of people, including myself, struggle with reading directly from a textbook and actually retaining all of the information. 

Well my friends I am here to change that [queue the victory music]. Recently I discovered a reading strategy known as the SQ3R technique. It stands for Survey, Question, Read, Recite, Review. I’ve found this technique to be extremely helpful when it comes to reading through textbooks, and so now I’m passing this information onto my dear followers.

1. Survey

The first step in this process is to get a basic idea of what you’re going to be reading. Most textbooks have chapter outlines or a brief summary at the beginning of each chapter. Take about five minutes to skim through these. By doing this, you’ll have the basic structure of what you’ll be learning in your head. 

2. Question

This step will be repeated multiple times throughout your reading, so pay attention! Within each chapter, there are section titles that give you a vague idea of what the next few paragraphs will be about. This step asks that you turn the section title into a question. For example, we’ll say that our section title is “The Changing Role of the States.” You can turn this into questions such as “how did the role of the states change” and “which states changed and how.” When you turn the titles into questions, you end up looking for the answers while you’re reading rather than simply reading. This stops you from reading the same line over and over again.

3. Read

This one’s the obvious one. Read your textbook. Take notes while you’re reading. Write down all the important definitions, concepts, names, dates, etc. But remember to take breaks! Taking a three minute break for every twenty minutes of reading allows information to settle in your brain. It also helps with memory retention.

4. Recite

I’ll admit I’m still a bit uncomfortable with this step but it’s helped me a lot with remembering what I’ve read. Basically, this step asks you to summarize what you’ve just read out loud. I do this after each section, and then I summarize the whole chapter once I’ve finished the chapter. (Pro Tip: If you’re uncomfortable with talking to yourself, try talking to a recording device or summarize to a nearby friend.)

5. Review

Review, review, review. I cannot stress this enough. Read over your notes the day after, then the week after. Studies show that you remember 60% more of the material you learned when you review it the next day. Don’t forget you can review with more than just your notes! Make flashcards or foldables with the most important information in the chapter and quiz yourself! So many textbooks have quizzes online for each chapter, so use them!!!! I find mind maps to be super helpful in studying too. Reviewing is a super important step, so don’t think that you can forget about studying just because you’ve read through a chapter!

I might include that, as of recent, many professors have been saying that there is a fourth ‘R’ to this process: Relate. With this step you simply relate the information you’ve just read back to something important in your life. When you make connections with your reading, it becomes easier to remember the material. 

Well that’s all I’ve got for you guys for now. I hope this helps at least a few of you. Keep on studying guys, and good luck on finals!  ╚(•⌂•)╝

I’ve been here 8 hours I think they’re ready to kick me out.

finished my infographic project for chem!

The basics of Research Methods. There’s so much to learn in AS and more is added in the second year. In an exam you could be asked to state which hypothesis is being used in an example, which experimental method would be best for a situation, or to create your own research plan.

did some review for our botany quiz on monday! i accidentally fell asleep throughout the entirety of our teacher’s three-hour lecture, but thank the heavens for powerpoint presentations aaaa

the thesis progress journal

it’s all based on louise desalvo’s concept of a process journal for writers, from her book ‘the art of slow writing’ which i read way back in 2014 but has stayed with me all this time. she based that concept on sue grafton’s journal, which “stands as a record of the conversation she has with herself about the work in progress.” desalvo talks about her own process journal : “to plan a project, list books i want to read, list subjects i want to write about, capture insight about my work in progress, discuss my relationship to my work (what’s working and what’s not, whether i need to make changes to my writing schedule, how i’m feeling about the work)” 

her view of the concept is so interesting and can easily be applied to grad school : “keeping a process journal helps us understand that our writing is important work. we value it enough to plan, reflect, and evaluate our work. a process journal is an invaluable record of our work patterns, our feelings about our work, our responses to ourselves as writers, and our strategies for dealing with difficulties and challenges.”

she says, and i quote : “our progress journals are where we engage in the nonjudgmental, reflective witnessing of our work. here, we work at defining ourselves as active, engaged, responsible, patient writers.” and like ???? yes, go off louise!

every week i make an entry with my three to five priorities. since i currently still have seminars, my entire week cannot be dedicated to my thesis, so these priorities allow me to really focus on specific things. they can be bigger or smaller depending on the amount of time i have to work on my thesis.

every day i work on my thesis, i make an entry. i try to answer two questions : “what did i do that day to make progress on my thesis?” as well as “how am i feeling & what i can do to feel better?” i also choose two to five specific tasks to achieve that day and write about the progress. for example, if my task is reading an article, i’ll write it down, check the box once i do it and write a summary of the “experience” (how was the article, was it useful for my research, should i read more of that author’s work, etc.) that way, i can look back at previous tasks, know what happened and learn from it.

i also use the journal almost like a bullet journal (the OG kind) with ongoing lists of important things. of course, there are some to do lists here and there (even though i prefer having my comprehensive task list on todoist), but it’s mostly things like

names of people who have helped me so i can thank them in my thesis

call numbers of books to borrow or archives to consult

research hypotheses 

things to look for in the archives i consult

questions to ask my professor/advisor/archivist/etc.

issues that need to be fixed in my thesis

books/articles to read

additional things to research

i also use it as a regular notebooks for all things thesis. one of my seminars this semester is a methodology course, so i take notes in my journal as reference. i also sometimes will write some reading notes if i don’t have my computer on me, such as key quotes or arguments. also, all of my notes from meetings/calls/emails with my advisor are put in the journal, as well as a any pertinent meeting notes (with an archivist, fellow student, my mom, etc.) lastly, sometimes it just becomes a catch all for brainstorm sessions and random thoughts.

for me, this thesis progress journal is the best way to take a step back from the actual work and reflect on what i’m doing, good or bad, and what i can do to make things better, but most importantly, it allows me to understand my progress.

stats notebook index set up lookin hella fine
