When I took admission in the electronics department I never thought that I would do code or design something called as the website, to learn something, where coding stuff would be included, was next to impossible for me, I thought I just need to learn about circuits but as semesters passed I realized being an engineer doesn't mean to restrict yourself in just one field you need to learn a variety of things to excel in your career. Genuinely speaking I never loved coding and that was the main reason I took electronics as my department but I never did know that at a point in time I have to learn it anyway.
At first, it was too frustrating as to do something you don’t like at all is a very tiring thing but as time passed I started liking things I started learning things. Beforehand I wasn’t aware of a single programming language but as I learned one then I felt it wasn’t that tough, all that needed was practice. Then I came to know that the websites I saw can be made by me too. At first, I was fantasized about how people made this but as I started learning and making my websites I enjoyed it and more I enjoyed more I wanted to learn new things, and this way I opted for web development.
And as said creating software isn’t that easy. There are a ton of things to be considered. The more you create the more you will learn. There are three responses to a piece of design – yes, no, and WOW! “Wow is the one to aim for”. And with this aim, I looked forward to excelling myself. I started from basic HTML and reached till react and this journey was amazing. I started loving to learn more and more and am still trying to gain more knowledge to make more beautiful websites. And as said “A successful website does three things: It attracts the right kinds of visitors, guides them to the main services or products you offer, collect Contact details for future ongoing relations.”
I will try to fulfill these criteria and excel further!!

Stereotype Threat
Perception Becoming Reality
June 7, 2015
I remember learning about sterotype threat in my into psychology class, but at that point it was just a fact that I had to engrain into my head in order to regurgitate it back onto yet another multiple choice exam. Until now, I've never really thought about my relationship with sterotype threat and how it has affected myself, my friends, and my peers.
I think the greatest way to combat stereotype threat would be to create a neutral environment where no individual's innate, unchangeable qualities are accentuated. Everyone should of course still be traeated as an individual, but every individual should be treated as if they are on a level playing field. I think DBC has already done a great job of this in emphasizing the growth vs fixed mindset and defining intelligence as a malleable entity rather than a fixed quantity. This maked me think that I have experienced stereotype threat in my DBC experience in that I have been projecting my beginner-ness onto myself. There have been a few times where I have gotten frustrated and fallen into a loop of "I'm such a noob, I can't learn this" thoughts, but DBC and especially the other people in my cohort have done a great job of being encouraging and assuring me that even a noob can do this.


Speech
Ian Stockford's speech to the Association of Colleges Annual Conference.
Good afternoon and thank you for the invitation to come and speak with you today.
As you know, I’m here to talk about the quality of GCSE and A level marking. We’ve just heard from one of the exam boards about their take on this subject and I’ll be talking a little more about the regulator’s role in this process.
I’d like to begin by saying that I don’t believe there is a ‘crisis’ in exam marking, as suggested by the title of this session. But that’s not to say that there aren’t concerns which have been expressed by a number of people within the sector about the quality of marking, and – given that you’ve chosen to attend this session above others that are available to you – probably by many in this room.
We know from our annual perceptions survey that, of those that chose to respond, around 60% of headteachers and a third of teachers don’t believe that the marking of GCSEs is accurate. The proportion is a little lower for A levels at 44% of headteachers, but this still reflects concerns amongst those that responded to our YouGov poll following the summer 2014 exams. But what are the facts? And is the apparent concern over quality of marking justified?
I hope to reassure you in the next few minutes that the system is not in crisis and, along with that, I’ll outline what we’re doing to secure delivery of high quality marking by exam boards.
I’d start by saying that we absolutely recognise that the current system is not perfect. Early last year we published the results of a year-long investigation into the quality of GCSE, AS and A level marking in England. That report concluded that, in general, there are good controls around the marking system delivered by exam boards. But, of course, there is always room for improvement, and in our report we identified potential actions in several areas.
These actions included the need for better monitoring of marking quality and for quantification of that quality of marking. It highlighted the need for better capture of the data during live marking and mechanisms to feed those data back into the marking process. This is to drive improvement during the live marking process but also in post-hoc analyses. The work also identified the need to re-design the enquiries about results and appeals system so that when there are genuine errors in marking there is an appropriate system in place to address these instances. And, I’ll say more on this in a moment. The report highlighted the need for improvements to be made to the design of mark schemes and also the need for improvements in the understanding of the marking of those within the system.
So what are we doing on this?
One important consideration for any regulator is that its regulations don’t stand in the way of innovation and, indeed, that we incentivise developments that are going to add quality. An important innovation in marking that was discussed at length in our report, and is in the process of contributing to improvements in the system is the introduction and increased role of on-screen marking.
On-screen marking has a number of direct benefits. Yes, it helps to improve the security and speed of the logistics around marking, but it also facilitates item level marking. That is the distribution of parts of a single student’s exam paper across a number of examiners. This approach reduces the effect of bias caused by student responses to the rest of the exam paper and allows examiners to focus solely on the quality of response they are considering at that moment. This approach also reduces the influence of a single examiner on an individual student’s script balancing any slight variations in standard across the question paper.
The immediate and electronic availability of the granular data from the marking process opens up a wealth of opportunities for exam boards to implement some sophisticated examiner monitoring and has the potential to improve marking quality through better identification and removal of anomalous marking.
But there are a number of indirect benefits too for us as regulator. The live monitoring processes that exam boards use provides us with the potential for a valuable data led insight into the controls exam boards have in place. We’re currently looking at ways that we could use these data from exam boards to better effect to enable us to hold exam boards to account without this use of the data having any unintended consequences on the exam boards’ practices.
Along with the technical and technological benefits, we do recognise that the move to on-line processes also introduces its own challenges. These include the technological barriers that it presents to some examiners – meaning that they may feel unable to confidently engage in marking – and the potential for the electronic marking systems to represent a critical point of potential failure in the successful delivery of marking. We will be taking a keen interest in the way that the exam boards are addressing these challenges and managing any risks that exist.
As I mentioned, our report also highlighted the importance of mark scheme design and the need for action in this area. In the lead up to the summer 2015 exam series, exam boards produced quality of marking action plans focusing on assessments where they had previously identified particularly large numbers of changes through the enquiries process.
When it comes to the design of mark schemes for extended and complex responses there is no magic solution. Indeed, the aspects that make an effective mark scheme can be somewhat counter intuitive. What we do require from exam boards, however, is to have effective processes in place to be able to evaluate the performance of their qualifications and to act on the findings of those evaluations. So rather than a magic solution, we expect exam boards to evaluate and refine their mark schemes on an on-going basis to optimise their designs.
Taken together this paints a picture of a number of quite significant incremental changes that should have a positive impact on the quality of marking year on year.
So how do we square that with the perceptions of reducing marking quality?
Part of the problem are the data widely used as a proxy for quality of marking. Typically the data used for this purpose comes from the enquiries about results system. However, it’s not reasonable to make assumptions about the direct link between EAR data and marking quality. And there are two primary reasons why the assumption is flawed:
It’s the second of these points that I’d like to focus on. One of the distinctive things about general qualifications in the UK is the combination of question types that exam boards use to assess students. These include short answer or objective questions which only have one right answer. They also include questions which require longer answers for which markers need to apply an element of judgement. Therefore it is entirely possible that for this type of question, a student might legitimately be given a different mark by two different markers marking the same answer, who are equally capable and experienced. That would not necessarily mean that either mark is wrong, as both could represent a reasonable application of the mark scheme.
Earlier this year we carried out some research looking at how potential marking errors are reviewed as part of the enquiries about results process. We found evidence that, in the current system, exam boards rightly correct genuine marking errors but that they can also sometimes change legitimate marks. This can give a misleading impression about the number of marking errors made and means that enquiries are not a good proxy measure of marking quality.
We will report data for this year’s enquiries about results in December, but they have risen year on year, and I probably won’t be giving too much away in anticipating a continuation of that picture this year.
Rather than using the enquiries system as a source of data of marking quality it is more important to consider the effectiveness of that process in delivering what it is intended to do – address instances of marking errors. As I’ve said, the significant concern that our research uncovered was the potential for students to be awarded additional marks where the original mark they received represented a perfectly reasonable interpretation of the mark scheme. This is problematic from the perspective of fairness across the system since schools or parents who can afford to pay for a review of their marks may be given an unfair advantage, not because they are getting marking errors corrected that they wouldn’t otherwise but simply because they are seeking a legitimate mark that they have been awarded to be overturned.
To reflect these findings, we will soon be holding a public consultation on proposed changes to be made to our regulation of the enquiries about results system and I hope you will engage with that consultation process. These changes would go hand in hand with other changes that seek to further improve and provide greater transparency on the quality of marking.
For example, we are going to identify metrics which will help us to more directly measure the quality of marking avoiding the current reliance on enquiries data as a proxy. We are conducting research in this area and when we have developed some proposals for this suite of metrics we will invite exam boards and other stakeholders to agree the best approach for measuring and reporting on marking quality.
Finally, we welcome all efforts to encourage good teachers to play their part in marking and awarding. I know that marker capacity and planning are being actively considered by exam boards and we will continue to engage with them to assure us of their ability to get the job done and to the highest possible quality.

Members of the kite surfing clubs “Spilt” and “Komin” were preparing for a new season by cleaning the beach when they came across a pile of battered bottles. A young member of the club, Matea Medak-Rezic, noticed that one of the old bottles had a message inside.  I hope we can keep in correspondence. I said I would write. Your friend always, Jonathon. Nova Scotia '85." The message and the bottle had travelled across the Atlantic Ocean, through the straights of Gibraltar, around the Mediterranean Sea, and into the Adriatic Sea before washing up on the Dalmatian coast. That's a journey of around 4,000 miles as the crow flies, but this bottle probably made a journey at least five times longer.
 A 13-year-old Russian, Daniil Korotkikh, was walking with his parents on a beach when he saw something glittering in the sand. “I saw that bottle and it looked interesting,” Korotkikh said. “It looked like a German beer bottle with a ceramic plug, and there was a message inside.” His father, who knows German, translated the letter, which was carefully wrapped in cellophane and sealed with a medical bandage. It said, “My name is Frank, and I'm five years old. My dad and I are traveling on a ship to Denmark. If you find this letter, please write back to me, and I will write back to you.” The letter, dated 1987, included an address in the town of Coesfeld.

These first couple of weeks have been an amazing ride. Do read my first blog summarizing my project and objectives here. In the following blog, I'm going to summarize my work, the objectives I completed successfully and the work that still remains to be done in this regard.
Objectives completed:
Most of my time during these weeks was spend on writing operator tests for the ONNX ops. I successfully wrote about 60 tests for different operators. One big hurdle I was able to overcome was the poor performance of models. I realized the source of this error after I came across a few discrepancies in the tests, and fixed them asap. I got to learn a lot in this process, as I wasn't used to writing tests before.
The second big achievement was loading quite a few ONNX models into Flux. I was able to load the SqueezeNet, DenseNet121, ResNet50, VGG19, ZfNet, GoogleNet into Flux. While most of the models except for GoogleNet and ZfNet had a pretty good performance (the VGG19 actually had a slightly better performance that the VGG19 currently hosted on Metalhead.jl), I came across a few legacy issues in a few models.
The GoogleNet and ZfNet models had Local Response Normalization layers, which Flux currently doesn't support. So, I had to manually bypass this entire layer. As a result, the performance was affected.
Quite a few models used asymmetric padding. As advised by my mentors, I used to convert most of the asymmetric paddings into symmetric ones, with a little depreciation in performance. For example, padding of the form (0,0,2,2) was implemented as (1,1,1,1). This was fine as far as a few models were concerned, but many showed asymmetric padding which cannot be converted to symmetric ones, without changing the expected output shape. For example, changing (0,0,1,1) to symmetric padding isn't possible. The only way around this would be to introduce support for asymmetric padding in Flux.I got to learn a lot in this process. I found errors in a few ONNX models and I opened issues in the respective ONNX repositories (here). I also encountered an error in Flux layers, which was changing the type of output as compared to the input. The issue I raised in Flux can be found here.
I also opened a Pull Request in FluxML/Metalhead.jl, where I added four more models to the Metalhead repository. The PR can be found here.
Objectives for the next three weeks:
Implementing Local Response Normalization (LRN) in Flux. I'm currently working on this and implementing it by referring to the research paper by Krizhevsky et al, which can be found here.
Keras.jl: I have already begun work on this (here). Rather than generating code, (like ONNX.jl does), I'm working on loading Keras models directly into Flux. I've been able to get the MNIST classifier loaded into Flux. The current impediments in this domain include increasing performance of the models. The MNIST model loaded doesn't have a good accuracy, so I need to investigate the reason behind this. Also, once I get this running for MNIST, I will expand its functionalities to include other complicated models.
ONNX.jl models: The ONNX models repository is updated frequently. As soon as the correct models are updated, I will resume testing and loading them into Flux.
Conclusion:
The next few weeks are certainly going to test my programming skills. However, I'd like to thank my mentor,
Phil Tomson for taking time out from his schedule to help me and for his continuous support and guidance.
I'm pretty confident that I would be able to meet most of the objectives under his supervision.
Hoping for the best!

Iraq officials: Protesters surge toward Baghdad’s Green Zone
by Qassim Abdul-Zahra, The Associated PressBAGHDAD — Iraqi security and medical officials say protesters have pushed closer to the Green Zone, Baghdad’s fortified seat of government, after security forces pulled back following a night of violent altercations.
The officials said Saturday that protesters took control of the strategic Khilani Square and part of Sinak bridge leading to the Green Zone, which houses Parliament and several foreign embassies.
Security forces are still deployed on part of the bridge in order to block the protesters from pushing into the Green Zone.
Officials say a roadside bomb killed three people and wounded 18 late Friday near Tahrir Square, the epicenter of the protest movement. Another roadside blast in the southern city of Nassiriya wounded 18 that same evening.
The officials all spoke on condition of anonymity in line with regulations.

It is easy to implement row grouping using the flexible template driven approach of the p-table. In this example, sorting is enabled by default to sort the data by brand initially and then a rowGroupMetadata object is created to represent how many rows a brand should span along with the rowIndex of the group. Similarly multiple field grouping can be implemented as well.
Group customers by their representative.

In our free time, we enjoy goofing off on the piano! Here's a clip -enjoy!
Meet the Girls in the Balloon!
Thanks for taking a look through our website! Right now, we're both high school seniors at the Plymouth Canton Educational Park. A year ago, HTML and CSS were just scary acronyms, and notepad was an unused icon burried deep inside our computer. However, after a year filled with coding, computer programming classes, searching for lost semicolons, copious amounts of caffeine, and an amazing Comerica Internship, we've certainly changed! In our free time, we enjoy hanging out with friends (and catching up on sleep!) We're looking foward to college next year and going into technology-related fields.Past Computer Classes:

- Social Media Icons thanks to DesignDeck
- We modified source code from menucool to create a javascript slideshow on the front page. We changed the size, the number of slides, added captions etc.
- We also used the Jquery javascript library (found here )and the garagedoor function from gayadesign to create the navigation animation. We modified the effect by changing the size, adding our own icons, adding our links so it would look like the icons were simply "bumping" upwards instead of being like a "garage door."


BigNum in pure javascript
npm install --save bn.js
```js const BN = require(‘bn.js’);
var a = new BN(‘dead’, 16); var b = new BN(‘101010’, 2);

There are several prefixes to instructions that affect the way the work. Here is the list of them in the order of appearance in the function name:
i
- perform operation in-place, storing the result in the host object (on
which the method was invoked). Might be used to avoid number allocation costsu
- unsigned, ignore the sign of operands when performing operation, or
always return positive value. Second case applies to reduction operations
like mod()
. In such cases if the result will be negative - modulo will be
added to the result to make it positiveThe only available postfix at the moment is:
n

When doing lots of reductions using the same modulo, it might be beneficial to use some tricks: like Montgomery multiplication, or using special algorithm for Mersenne Prime.
To enable this tricks one should create a reduction context:
js
var red = BN.red(num);
where num
is just a BN instance.
Or:
js
var red = BN.red(primeName);
Where primeName
is either of these Mersenne Primes:
'k256'
'p224'
'p192'
'p25519'
Or:
js
var red = BN.mont(num);
To reduce numbers with Montgomery trick. .mont()
is generally faster than
.red(num)
, but slower than BN.red(primeName)
.
Before performing anything in reduction context - numbers should be converted to it. Usually, this means that one should:
Here is how one may convert numbers to red
:
js
var redA = a.toRed(red);
Where red
is a reduction context created using instructions above
Here is how to convert them back:
js
var a = redA.fromRed();
Most of the instructions from the very start of this readme have their counterparts in red context:
a.redAdd(b)
, a.redIAdd(b)
a.redSub(b)
, a.redISub(b)
a.redShl(num)
a.redMul(b)
, a.redIMul(b)

Gear Check
What’s in your bag?
Pack smart and use the bag-check service on race day.
Like many distance races, the Blue Cross Broad Street Run offers a gear check service for runners. This convenient service shuttles your gym or duffle bag from the starting area to the finish line.
Not only does this mean that you can wear sweats before the start of the race, but you can also bring along some dry clothes, socks, and shoes for post-race.
Things you might want to pack:
- change of socks, shoes, or sandals
- change of clothes
- a hat
- favorite sports recovery bar
- sunglasses/sunscreen
- wet wipes
- tissues
- extra safety pins for attaching the race bib
- band aids
Things not to pack in your gym bag:*
- money
- cell phone
- keys
* We realize that many runners need these items for race day. In those cases, we suggest wearing an elastic waist pouch (it’s like a fanny-pack that doesn’t bounce around) on race day. Also, while tying keys to shoelaces is a common practice of runners, please realize the risk you run of loosing your keys.
How to use the gear check
- Look for the yellow school busses above the start line area.
- Bring your own gym or duffel bag for your gear.
- Mark your bag with the tag supplied on race day. Any bag that is not properly marked will not be accepted.
- Place your bag on the bus that displays the number that corresponds to your race bib. This system is designed to help you locate your bag at the finish area.
- At the finish, display your official race number to the volunteers and your items will be returned. Please be patient and courteous, as this is a big job for our volunteers to handle.

Amicus Curiae is a free student resource for Political Science students, Lawyers, Paralegals, etc. My application allows for these users to search through a live court docket database. This is my Capstone project from Suncoast Developers Guild utilizing a full stack environment. I used HTML 5, CSS 3, and React.js to create the front end to allow for full CRUD support. I utilized C#, .NetCore, ORMs, and EntityFramework for my back end to allow for full CRUD functionality in my endpoint controllers.
This project is a functional version of minesweeper created in React.js making an axios call out for the game board. The game comes with several separate difficulties and is fully functional for a play through. Just watch out for the mines!
Color Picker allows the user to fully manipulate the color spectrum playing with Hue, Saturation, and Light. This is a feature test application showing the dynamic functionality of slide bars. I created this using React Hooks to practice with the more dynamic tools.

Acuitas Clinical
Patient Relationship Management including a fully paperless patient journey
This is recommended for the independent ophthalmologist who:
Want - their practice to run more efficiently and paperlessly, desire to be at the leading edge, want to enable staff to provide
a better level of patient service, welcome a less administrative heavy channel of communication with patients, wish to share
expensive diagnostic equipment, reassurance that that patient data is secure, can see the value in freeing staff and utilising
each member to share and enhance the patients journey and strive to have more control and visibility of staff/practice
performance.
Do not want – tight control on stock, locked down cash management, links with other practices. |

New Site Design
November 12th, 2014
While I was working on our JavaScrip Cheat Sheet challenge last week, I was forced to confront the fact that my current website screamed amateur. The design was sloppy, at best, my blog posts did not link back to my site, and it was completely unresponsive. The immersive part of DBC had not even begun yet, but it was painfully obvious that no one would ever hire me as long as my personal website looked like this. I decided that I needed to do something about it immediately.
My biggest challenge was overcoming my fear of design. I have always considered myself "artistically challenged". I was a straight A student my whole life in every subject, except for Art. The way my mind naturally functions, I do not notice elegant designs, cool fonts, and perfect color schemes. To overcome this fear, I signed up for a free account at teamtreehouse.com and enrolled in their building a website course.
The course is absolutely fantastic. Overall, it took me somewhere between 10 to 20 hours to get through all of the videos, quizzes, and code challenges. It was the perfect way to freshen up my CSS/HTML skills a week before Phase 1. We have learned Ruby, SQL, and JavaScript since covering CSS and HTML, and I was in need of this kind of refresher to help me remember the proper syntax. I will also more than likely be a Team Tree House member for life, as I cannot say enough about well structured and easy to follow their courses are. If you are interested in keeping your skills sharp for a small monthly fee, I strongly encourage you to check out a basic account at teamtreehouse.com
My goal was to build a simple site with a clean/sharp design. I have noticed that most web developer applications require you to send a link to your personal site, so I wanted it to look professional. I wanted to be able to display my blog, my (future) portfolio, some information about me, and the best ways to contact me. I think I have absolutely nailed it on all of these goals. On top of that, I also learned how to make my site responsive (seriously play around with your browser window and watch my website morph live right before your eyes!) and it should be fairly easy to scale as I add new blog posts each week.
I requested feedback from fellow DBC'ers who have commented on my blog in previous weeks. They all agreed that my site is infinitely better than what it was which was a good thing. Some other feedback that I received was that one person thought it was too boring and I should add some more color to it. I can definitely see his point, as it is mainly a white page, but I think this will change when I start adding more projects to my portfolio. Another great bit of feedback I received was that some of my images were too small to read in my blog posts, and so I made sure to resize them.
I also went through the process of registering my own custom domain name, frankD.co. It's not a dot com, but my last name is fairly long and hard to spell correctly, so I decided making it shorter and having a .co would ultimately be more beneficial. I am currently in the process of pointing this domain to my GitHub pages, but the process may take up to 24 hours so we will see how this all plays out.
This is my last technical blog post before moving to New York City and participating in the immersive part of DBC's curriculum. Right now it is a roller coaster of emotions. I am excited, anxious, eager, and scared. Overall I am looking forward to continuing my education and doing my best to articulate what I learn in these blog posts.
As always, thanks for reading.

submodule¶
Datasets¶
Kevin Fung - Github Alias: kkf18
Stage 2: nested class to prepare datasets. This module contains the features to create new datasets for machine learning. The idea is to first create your own Spark DataFrames stored in sets, then to finalise the Spark DataFrame sets into a dset object stored in datasets.
Statistical visualisation tools are provided in aid of feature selection.
dset objects contains the necessary data splits for machine learning e.g. feature set, label set.
