                                 Decoding the life of a computer engineer:

                                      Life and experiences of Md. Islam

 

     “Never think you know enough. Because in the ever changing and improving world of technology what you know today might just be obsolete tomorrow,” said my interviewee Md. Islam. A recent graduate from City College of New York and the current software engineer at a startup company. As I sat in the quite New York public library and listened to him talk about his life experiences, one thing became very clear to me; This was not just an advice he had for me but a rule that he himself follows. Mr. Islam has always loved working with computers and through determination and patient he was able to turn his love into a career.

     His love for computer goes back to his high school years. Md. Islam went to a New York high school. He loved spending time in the computer lab. Learning about different functions in the computer and what it can do was always fascinating to him. Right after high school he enrolled in City College of New York. One of his favorite aspect of college was the internships he did. One of his first internship was in a research institute, where he worked with other engineers on designing and programming Python based front-tend software. He has also interned for companies such as JP Morgan Chase &CO. and Gleam Inc.  As an intern most of his job involved working with other engineers and developing different software. According to Mr. Islam, Internships are important for all students regardless of the major they study. Because even though sometimes doing these internships can add long hours and extra stress on the students academic life, experiences and the life skills that are acquired through these internships are well worth it. He believes that college play an important role in building a successful career and life. But some of the skills that are needed in the real world to be successful cannot be learned in a classroom. Mr. Islam credit a lot of his life success to the knowledge he attained from college and the experiences he acquired from internships.

       His first official job was with IBM. When asked about the application process his answer was “Long”. The process started with an online application, then a 4-hour technical interview over the phone including an online coding and language portion as well. Followed by an on the job training/interview. According to him, the whole process took about a week before he was offered the job. As it turns out lot of the responsibilities of a software engineer includes working with other software engineers in a group, on different projects within a specific time frame. Many of these projects consists of team collaboration, daily or weekly meetings, writing reports, and emails to the supervisors or project managers. A lot of these projects also included a big presentation in front of the boss or the board at the end.

       Now IBM isn’t the only company Mr. Islam has worked for.  He is currently employed at a startup company called Gemini. Not to confuse with the Zodiac sign. As defines in their website: “Gemini is a next-generation digital asset exchange and custodian headquartered in New York City. We are fully-licensed and fully-regulated. We allow both individual and institutional customers to buy, sell, and store digital assets (e.g., bitcoin, ether, or Zcash). Gemini.com is a firm that deals in storing and exchanging cryptocurrency and digital assets. According to Md. Islam the application for this job followed similar guidelines as IBM.

     A lot of the work Mr. Islam did for both IBM and Gemini were group projects. To get an idea of his day to day responsibilities and communications, he gave me a little peek into the duties of a software engineer. At IBM most of the communications were done through email. About 5 to 6 emails were received and sent in a day between coworkers and project managers. Along with daily or weekly meetings depending on the complexity of the projects. At Gemini the process is a bit different. Engineers usually meet daily to discuss their projects. A lot of the communications at Gemini is done through a platform called Slack. Mr. Islam and his group messages each other from within the app about any progress, questions, or confusion they might have on the project. Slack is a messenger-based platform primarily design to work in office environment. It follows the same principle as modern-day Facebook messenger or WhatsApp. Slack is mostly used as a mean of communication between peers and colleagues. When it comes to project managers or the boss emails are still the best form of communication. According to Mr. Islam at Gemini about 3 or 4 email is exchanged in a week but within slack an average 10 to 15 messages are exchanged in a day. At both jobs completion of a projects often times required either a written report or a presentation.

   In a world where technology influences all aspects of our life. Sometimes choosing computer science as a major become a logical choice for a lot of students. I went into this interview thinking it was just another project I have to do for my class. But after doing this interview, talking to Mr. Islam, I realized why I chose computer science as my major. We may lead different lives, but our love and passion to learn about computers and its impact on our life is the same. Listening to him talk about his experience and his obstacles with the changing world of technology, has reassured me of my choice. Because one day I hope to be in a position like Md. Islam and be able to encourage an aspiring engineer to follow his or her goal and give them the guidance, that I have received from Md. Islam.

 Guggenheim Technology Internal Audit

 Midtown, Manhattan NY

 

   Dear Sir or Madam,

                                      My name is Delwar Hussain. I am currently a first-year student at City College of New York with a major in computer science. I am applying for an internship with the Guggenheim technology. Guggenheim technology’s is an amazing firm with investments, corporate and public funds with an earning of well over $200 billion worth of assets. Not to mention Guggenheim technology has won 2 consecutive Lipper Award in a row. Working for firm such as this would be an honor and an accomplishment. I believe, I am a strong candidate for this internship because the requirements for this internship is the experience I have acquired working in the hospitality business.

   Excellent communication and leadership skills are the first thing required in this business. Along with the ability to follow company rules and policies. To be adaptive and be logical in any given situations and the aptitude to deal with customer service and management communications. As a server I learned how to work with teams and be a team player and help my coworkers. I was also a server trainer for both companies and as a trainer I was responsible for training new employees with the day to day jobs. To sit with the management and give them reports and evaluations of the trainees. I am also well versed on the Microsoft Office suite 2010 and 2016. Along with office 365.

   I am currently available and would like to request an interview at your convenient time and place. Thank you for your consideration. Hope to hear from you soon. My contact information is (347) 435-8630 or dhussai000@citymail.cuny.edu

            More Buses, Less Fusses: Improving CCNY Shuttle Service

 

 

Introduction:

 

In the city, public transport is not only a part of daily life, it is essential. According to the MTA, nearly 400 thousand people ride the buses in NYC every day(1). With so many people taking the bus, one would expect the service to be exceptional. However, we have found the opposite to be true. The CCNY Shuttle tends to be crowded, and people are waiting longer than they would like for each shuttle. That is why we are proposing to increase the number of shuttles running by one bus (through purchases or rental) during hours of peak ridership, and to eliminate the 145th stop on the shuttle route. These actions would both decrease how crowded the buses are while at the same time decreasing the time it takes for the next bus to arrive. This will not only improve the wellbeing of the students, but improve the college as a whole.

 

Action plan:

 

Increase the Number of Shuttle Buses by one:

Removing Shuttle Stop:

• Coordinate with Wendy Thornton at Student Affairs to remove the stop at 145th street.
• Present survey (figure 1) as evidence as needed. (See cost benefit section and/or reference section)

Figure 1

• Once approved contact George Varian in facilities management to coordinate the new route.
  • Wendy Thornton: Interim Vice President of Student Affairs
    • Office: Wille Administration Building, 160 Convent Avenue, Room A 204
    • Phone: 212-650-5425
    • Email: studentaffairs@ccny.cuny.edu

 

Cost/Benefits:

 

            There are monetary costs associated with this endeavor. The two options are summarized below. A more detailed breakdown is available in the reference section (3).

   If we were to rent a bus, it would require less paperwork and a more streamlined approach. All costs would be included in the listed price. We would also have less liability as the rental service would cover the insurance as well. However, if we purchase the shuttle bus and hire our own workers as well as insure ourselves, we can save $464,602.86 over the course of 7 years. Even after the initial purchase the purchase plan is still cheaper. Clearly the purchase option is the least expensive choice both in the short term as well as the long term.

            There is a cost associated with the loss of the shuttle stop at 145th street. Some students use this stop, but according to our survey, 69% of the people riding the shuttle are taking it to the 125th stop. Also, an overwhelming number of responses (93.2%) indicated that they would prefer less stops if it would mean that there would be a greater frequency of shuttles.

            If this plan of action is taken, there are numerous benefits for the students. Surprisingly, out of over 100 students surveyed, 41.7% said that the shuttle was moderately crowded with 38.6% saying that the shuttle was very crowded. 52.3% of students also said that they wait 5-10 minutes for the shuttle, and 28% said they wait 10-20 minutes for the shuttle. Increasing the number of shuttles running would both decrease the amount of time to wait for the shuttle, as well as the number of people on the shuttle when it arrives. In addition to the direct benefits to the students, there are potential benefits for the college as well. Having a more robust shuttle service could be marketed to potential students, which would increase the tuition revenue for the school.

Memory cards are one of the most convenient way to store and transfer all kind of information. In this modern world where pretty much everything requires some sort of computer programming, Memory cards have become somewhat irreplaceable. Memory card have been around since the invention of computers and comes in many forms and sizes. But for this description I will focus on The Micro Memory Card.

 

History of Micro SD card:

SD cards (Secure Digital) was first introduced back in 1999 by the joint effort of SanDisk, Panasonic (Matsushita Electric) and Toshiba. In 2000 the three companies created the SDA (Secure Digital Association) and SD-3C, LLC. SD-3C, LLC is the company that provides licenses and control all property right associated with the SD memory card and SD products. In 2003 SanDisk introduced the MiniSD cards and in the same year SDA accepted MiniSD as a small form factor of it SD production. A MiniSD card has a length of 21.5mm and width of 20mm. Around the time smart phones were becoming popular in the consumer market. Chief engineers of Motorola and SanDisk conceived that the MiniSD card were simply too large to operate and fit into the phones storage compartment. Thus, in 2005 SDA accepted and announced MicroSD cards as its newest small form factor SD production. At first MicroSD cards were to be announced under the name TransFlash (T-Flash or TF); However due to a naming conflict with T-Mobile SDA later renamed the product as MicroSD cards.

Figure 2 Comparison of MiniSD and MicroSD card

Types of memory card and abbreviations:

There are currently 3 types of Memory cards in the market with different speed range.  MicroSDSC, MicroSDHC, MicroSDXC. All microSD cards have a length of 15mm and width of 11mm. MicroSDSC (Micro Secure digital standard capacity) is SDA’s first micro memory card. It has maximum storage capacity of 2GB (Giga byte) with transfer rate of 25MBPS (Megabyte Per Second). MicroSDHC (MicroSD High Capacity) introduced in 2006 has maximum storage of 32GB with transfer rate of 50MBPS. Micro SDXC (MicroSD eXtended Capacity) introduced in 2009 has the most storage capacity with up to 2TB (Terabyte) and transfer rate of 312MBPS. However, as computer and smartphones are becoming faster, more speed was added to the microSD cards. Depending on purpose of the memory card different category of speed is added. Refer to figure 3.

Inner workings of a MicroSD card:

MicroSD cards are convenient for their size. It is the smallest in its class and still able to store large amount of data. MicroSD cards mostly consist of 8 pins and circuitry. The pins are used to connect the card to the host device to read, write and transfer data. Everything else is done using Flash Memory. Flash memory uses electrons to store data in the card circuit cells and if needed can erase a whole block of data in an instant (Flash); As oppose to one at a time, thus the name “Flash Memory”.

A modern twist on an old trial:

An experiment on Dice roll probability

 

 

Delwar Hussain

Writing for Engineers

10/30/2018

 

 

 

Abstract:

The Dice rolling experiment is a simple way to see and measure probability. With each roll, a different sum is produced. When all the data is gathered, we will be looking for the most probable sum between all the rolls. Using Microsoft Excel, I am able to simulate the Dice rolls by using excels’ rows, column and functions. With each row producing different output of sum and ultimately using excels frequency function I am able to see that the most probable sum of the 100 dice throw is 7. Using the same Excel method, I have done the experiment with 1000 dice roll with the highest sum of being 7 as well.

 

 

 

Introduction:

With any probability experiment, we are dealing with uncertainty and trying to asses’ quantitative data. However, using data analysis, we are able to study and evaluate those uncertainty or measurements. In this experiment, we are rolling or scrolling down a pair of dice and studying each changing outcome and finally measuring a singular frequency for each outcome within expanding field 100 and 1000 rolls.

Hypothesis:

In this experiment, I am trying to see the outcome of dice roll experiment. Given 2 dice rolls with 36 possible combinations (Each die = 6 side, thus 6*6= 36), out of 100 rolls. The probability of seeing sums with higher number would be greater.

Materials

    Computer, Microsoft Excel and Microsoft Excel functions(fx).

Methods

Step 1: Label all the rows according to their perspective functions. Ex. Number of throws, die1, die 2, and sum. Letter A-I representing the column heading in Microsoft excel.

Step 2: Rolling the dice. To simulate a die roll in excel I used =RANDBETWEEN(1,6) function, for both dice. (1,6) to mimic 6 sides of a die.

 

Step 3:  Finding the sum. For sum, I used =B3+C3 function. B is die 1 column and C is die 2 column.

Step 4:  Select and drag. Using excels select and drag ability I selected the entire row of function starting with number of throws to sum and drag down to 100 from the corner. Thus, mimicking 100 dice throw.

Step 5:  Possible sum and frequency. Listing every possible sum, I could receive for each dice throw. Starting with smallest being the 2 (1+1), or the largest 12(6+6). To find the frequency of each sum in my 100 dice throw I first labeled a row frequency than underneath put in the function =COUNTIFS(D:D,”2″). In this equation D:D represent the column D. Because we are looking doe the frequency of a specific number in that column. Column D contains the sum of each throw. To use this function just click on D and it will select the entire column D. With 2 representing the frequency I am looking for. As I continue down 2 is being replace with the next number holding all other aspect of function constant.

Step 6: Looking for probability. Now I was trying to see what the probability of each frequency. For this, I simply take my frequency and divide it by the number of throws.

Step 7: Making a graph. To show my experiment in graph I start with the frequency and sum first. Selecting column G and H than choosing a bar graph from the insert ribbon (The box on top of the worksheet) and excel will put the data into the graph. Using the same method but with column Hand I we can also show a graph on relationship between frequency and probability.

The same methodology was used to create the 1000 dice experiment as well.

Result

The Result from Experiment A, 100 dice roll.

The result from Experiment A, 100 rolls

The result from Experiment B, 1000 dice rolls.

 

Analysis:

The purpose of this lab was to see the probability of dice roll, and my hypothesis was that the highest sum of the dice rolls would be the most frequent. However, as we can see from both experiment, sum with the greatest frequency and the probability is 7, with 6 different combinations between 2 dice. In the first trial with 100 rolls, we see that 7 is highest sum I can get. From the 100 rolls, 7 had a frequency of 16 and out of 100 probabilities of 16%. In the 1000 rolls experiment we have the similar findings. Where 7 was again the highest sum we could receive from those dice rolls. Even with a greater field of experiment sum 7 had a frequency of 189 with a 19% probability. From this 2 graph we can understand that in probability the number with the highest combination can impact the outcome. However, looking at the graph, we can also see that as the field of data expands our frequency and the graph starts to smooth out.

With the 100 experiment even though we have a highest sum the probability and the graph is not consistent. However, looking at the graph for 1000 experiment, we see that frequency and the probability is much smoother. In addition, as the experiment field expanded our sums started to cluster and higher number in the middle became very close.

Conclusion

This experiment was intended to show the probability of dice rolls and throughout this experiment. When studying probability there is never certain answer, but we can make educated assumptions from doing experiments. As we have in this dice roll lab. We can see that in probability even though there is no 1 answer, sum with the greatest combination does play a role.
