The Anatomy of an All-Nighter

This is already posted on my other blog, but I thought I’d reblog this, since the content here quite relates to what a mechanical engineer experiences at least a few times throughout his or her degree.

Swamped with work, somehow people still persevere and finish the job.  But how?  Probably through all nighters.  We’ve all done them at some point and it’s obvious that they aren’t good for our health.  Kindly sent to me by one of my blog readers, here’s an infographic on just what an all nighter really means to our health.

Maybe after this, we will all think twice about pulling all nighters!

Meeting Deadlines

Nobody really knows how long things take to get done.  When someone sets a project deadline, there is a high chance that there will be a delay.  Everyone has the thought of, “it won’t take me that long to do that, I just need to do X, Y, and Z”.  Nope.  A lot of people know it and think they can manage their time well, still nope.  A lot of people say “start early”.  While that sounds like common sense, a lot of people don’t do it.  Everyone thinks “oh I still have lots of time”.

For my fourth-year design project (8-month project), my team spent the first two weeks not really doing anything productive.  As a result, our team is now behind in a lot of the documentation work that should have been finished in the first term.  Also, one of our group members had to leave for personal reasons.  That took away 25% of our manpower.  It sounds like we’re not in that good of a situation.  To remedy it, each member of our team puts in twice the amount of time than what the professors expect.  The professors expect 8 hours a week for each person.  We each put in 16.  The idea of this is to help our team catch up from the setbacks we’ve gone through.  If we started earlier, we probably wouldn’t be in as bad of a situation.

For my Thunderbots project, a deadline for the robot design was set for 11 February 2012.  A design review was to be held so that everyone could help iron out anything wrong with the design.  Out of three designs for separate systems on the robot, none of them were finished completely.  I was in charge of designing the ball dribbling system with another teammate.  At the beginning, we didn’t really do much.  We didn’t really have a clear direction.  Once the project picked up we spent more and more time per week.  As we put more time into it, the more design problems we were faced with.  If we had more time, we could have tackled these issues sooner instead of dealing with them the night before.  We each probably spent at least 50 hours over 8 weeks getting the design ready.  We discussed a lot about how something would work or what would work better etc.  The night before the design review, we stayed up till 4am getting the design ready.  There were still some things missing in the design, but we felt we had enough to present for the design review.  It turns out that at the design review, we seemed to be better prepared than everyone else.  But regardless, we couldn’t meet the deadline.  If we spent more time at the start, maybe things would have been different.

We finished this CAD model in a night using notes and sketches that we prepared from our previous discussions

Starting early means less rushing at the end.  That’s what it comes down to.  Starting early reveals design problems sooner that can be fixed.  People just need to realize that time is of the essence from the start.  People in previous years try to make that point clear to students younger than them, but it almost always takes their own personal experiences for them to realize what has happened.  Everyone on the team needs to share the same mindset of starting early.  Even if one person starts early, it will be difficult for the one person to progress on things that depend on the entire team.  Regardless, the earlier a team starts, the less headaches there will be in the future.

Label Your Axes!

I don’t try to be up to date in American politics such as the upcoming presidential election in 2012, but I did come across this picture with the following caption, “Mitt Romney claimed this morning that he created more jobs in Massachusetts as governor ‘than this president’s created in the entire country.’ This chart shows the reality of President Obama’s strong record on job creation—21 straight months of it. Share it with your friends to get the truth out.”

I’m sure Obama’s campaign staff are quite competent (since after all, Obama became president), but I have no idea what those numbers on the vertical axis means.  On the top right corner it does say “Private sector monthly change, thousands” and then beneath it, it says,  “Total, excluding census”, which leads me to believe that that is a legend, but isn’t a monthly change in jobs different than the total number of jobs?  Am I reading it wrong?  With two entries in the legend, I thought I would see two graphs.  When it says “monthly change”, I’m assuming they refer to the “monthly change in jobs”, but it isn’t explicitly said.  The title implies that the units of the vertical axis are in numbers of jobs.

According to the caption, it seemed like the campaigners wanted to show that Obama did in fact create more jobs than Mitt Romney, but the chart doesn’t show that.  The graph just shows job creation differences between the two administrations over time.  It doesn’t show Mitt Romney’s personal contribution to job creation.

The graph does show the democrats in a positive light psychologically since jobs created being larger than zero is generally seen as a good thing.  Even if I don’t understand the units being shown there, it is a weapon to be used in the battle for the administration.

I thought making graphs were supposed to make things easier for people to understand?  Only if it is labeled properly.

Busy Time Ahead!

So it’s almost the end of the semester (~2 weeks), and the work still hasn’t stopped piling up. Little by little I’ll go through my giant to do list and by that time it’ll be the end of the semester and just in time for exams. A little bit more work then and it’ll be Christmas Break. Here are some things that I still have left to do for the next two weeks:

  • Capstone Design Project – Critical Function Prototype
  • Japanese 100 – Oral Exam
  • Japanese 100 – In-Class Composition
  • Manufacturing Processes – Term Project
  • Sensors and Actuators – Lab Report
  • New Venture Design – Business Plan
  • Thunderbots – Dribbler Design CAD

It will take a lot of work, but I’m up for it. At times, I feel that I’ve done so much work in one day that my whole body feels exhausted not physically, but mentally. Sitting there toiling away in front of the computer to finish that lab report, assignment, or intense research on Google for another project really takes its toll me. Taking study breaks are totally worth it. In fact, part of my study break is writing this post. Another form of study break that I take is playing Tetris. Here’s a video of me playing from a about a year ago. Enjoy!

Looking back at this video, I can probably play way better now!

Hello World

Hi I am Henry and I am one of the new blogger in this space.  For the next little while, I will be posting little tidbits about my life as a mechanical engineering student.  Right now, I’m in the middle of my fourth year studies in mechatronics engineering.  I am also a gamer and lately I’ve been indulging in a little bit of StarCraft II (and Modern Warfare 3 as soon as I get my hands on it).  I don’t really know what else to say here.

Anyway, here is a nice video of scientists investigating the nature of why cats land on their feet…in zero gravity…
