Smart India Hackathon: Horrible experience
Background:- Our task was to do load forecasting for a given area. Hourly energy consumption data for past 5 years was given to us.
One government official asks the following questions:-
1. Why are you using deep learning for the project? Why are you not doing data analysis?
2. Which neural network "algorithm" you are using? He wanted to ask which model we are using, but he didn't have a single clue about Neural Networks.
3. Why are you using libraries? Why not your own code?
Here comes the biggest one,
4. Why haven't you developed your own "algorithm" (again, he meant model)? All you have done is used sone library. Where is "novelty" in your project?
I just want to say that if you don't know anything about ML/AI, then don't comment anything about it. And worst thing was, he was not ready to accept the fact that for capturing temporal dependencies where underlying probability distribution ia unknown, deep learning performs much better than traditional data analysis techniques.
After hearing his first question, second one was not a surprise for us. We were expecting something like that. For a few moments, we were speechless. Then one of us started by showing neural network architecture. But after some time, he rudely repeated the same question, "where is the algorithm". We told him every fucking thing used in the project, ranging from RMSprop optimizer to Backpropagation through time algorithm to mean squared loss error function.
Then very calmly, he asked third question, why are you using libraries? That moron wanted us to write a whole fucking optimized library. We were speechless at this question. Finally, one of us told him the "obvious" answer. We were completely demotivated. But it didnt end here. The real question was waiting. At the end, after listening to all of us, he dropped the final bomb, WHY HAVE YOU USED A NEURAL NETWORK "ALGORITHM" WHICH HAS ALREADY BEEN IMPLEMENTED? WHY DIDN'T YOU MAKE YOU OWN "ALGORITHM"? We again stated the obvious answer that it takes atleast an year or two of continuous hardwork to develop a state of art algorithm, that too when gou build it on top of some existing "algorithm". After listening to this, he left. His final response was "Try to make a new "algorithm"".
Needless to say, we were completely demotivated after this evaluation. We all had worked too hard for this. And we had ability to explain each and every part of the project intuitively and mathematically, but he was not even ready to listen.
Now, all of us are sitting aimlessly, waiting for Hackathon to end.😢😢😢😢😢26
After you automate away task into a tool or program, do you tell your boss or keep it to yourself so they remain amazed at your efficiency and productivity?
And for data analysis ones, that you have godly data processing skills as you can somehow read a 1,000,000 line log file and find the root cause and other insights in an hour or minutes?5
I think another intriguing job asides programming is engineering (*for some*). A week has past and I've been on the hike assisting my beloved brother on his contracted engineering job while I am less occupied. The job is based on 🗼Tower analysis and It's quite risky as you'd have to climb up to 56 meters high just to take readings of antennas, and fix some other stuffs. The only thing I find intriguing about this job is his love for it, funny enough he also thinks I love the job too and I guess I'm guilty for his thoughts (*Sorry bro, I love the job for you not me*).
With my little experience so far on my *new brotherly job* I noticed the most hectic task isn't going up and down the tower taking readings but at the end of all operations, he'll have to gather the values and snapshots he took while on the tower to prepare reports on msword & excel for the other buttwags at the office (or home I guess)
then archive and sends via mail. Seeing this lengthy process I was forced to ask why he wasn't using any reporting tool like Jotforms or any other equivalent and I was willing to look up some recommendations for him, his reply was: "I'm already used to this form of reporting, its what I was trained with and what the company provided, nevertheless a friend of mine suggested something of such weeks back but I would have to pay monthly fee for its usage which is quite on the high side and I don't think I'd prefer that."
Sounds convincing but not enough, okay here is another deal: You use an android phone right? and at my office we work on system automation (*basically does not know what I do for a living probably thinks I'm a hacker the illegal one*), how about i design you an android app for you to capture the tower data and a PC software for you to auto generate the msword & excel reports, I can get this ready for you in less than 5 nights (*I've got less task on my desk, and was willing to take the timeout to prepare the solution that he needed, all I needed to hear for a kick start was an "Okay" just to be sure he wants it*) I suggested and re-assured but up to this point he still declined my offer and is willing to stick with his current reporting pattern (*Me died*).1
Today I had a full-day job interview for a junior data scientist position.
First I met the team which was only like half of everyone because apparently everyone was gone on Fridays. However the few there were really nice.
First task is to do some basic data analysis stuff even though I already spent a week on the coding challenge and sent them all my code/tasks. I log into my machine and create a new virtual environment but can't for the life of me figure out how to use the command line in windows to install packages. Turns out there is some problem with their proxy and they have to log me in on that. Then I am struggling on the keyboard because it's for a language different that my mother tongue and it takes me 3x as long to so the most simple things. All my shortcuts are out the window. Haven't a hard time typing parentheses and brackets. Start freaking out and have a panic attack mid task. I'm sweating bullets. I didn't even make it to the simple visualization tasks much less the models at the end. Time gets called and we all go to lunch and I'm freaking out on the inside the entire time. Angry at myself because I know I am better and just couldn't think.
After lunch I present my code and results from a coding challenge I did weeks prior. People from other teams get invited and I end up getting grilled for 2 hours by 15 people. Questions are flying in from all sides. They ask me almost everything I know about machine learning and some more. Under stress I forgot the name of the optimizer I used and couldn't answer some easy stuff because my mind was racing.
Right now I am on the train home and my body physically hurts. I am disappointed with myself and wish I could have shown up better. Never really froze up like this before.2
"Dear TitanLannister : You are in the final year. A lot of shit is happening around u. its now time to make a career and take tough decisions. What would you do?"
CHOICE 1: COMPETITIVE
>>>>background : "a lot of super companies like wallmart, fb, amazon, ms, google,.. etc simply takes a straight coding test for fresher placement. They ask tough bad ass level questions, but with right guidance, a hell ton of dedicated hours of coding, and making it to the top of various coding tests could make you a potential candidate"
>>>>+ve points :
- "You got the teachers and professionals with great experience to guide you"
- "a dream job come true.you can go there and join teams that interests you"
- "it was your first exposure to computer world. maybe you would like doing it again, after 4 years"
>>>> -ve points:
- "You have always been an average 70 percentile guy. The task requires 2000-3000 hours of coding an year. it will be hard and you always grow bored out of this pretty quickly"
- "Even If you did that , you stand a lesser chance because your maths is shitty.There are millions running in this race with brains faster than your IDE"
- "your college will riot with you because they expect 75% attendance"
- "You are virtually out of college placements, in which , even though shitty companies come and offer even shittier 4LPA packages($6000 per annum), would take a tough logical/aptitude based test for which you won't be able to prepare"
CHOICE 2: PROFESSIONAL WORK
>>>>background: "you always wanted to create something , and therefore you started taking android based courses. you have been doing android for over 2 years and today you know a lot of things in android. you might be good in other professional lines like web dev, data analytics, ml,ai, etc too if you give time to that"
>>>>+ve points :
- "you will love doing this, you always did"
- "With the support of a good team, you will always be able to complete tasks and build new things quickly"
- "Start ups might offer you the placement, they always need students with some good exposure"
>>>>-ve points :
- "Every established company which provides interesting dev work takes their first round as coding, and do not considers your extra curricular dev work. So you are placing your all hopes in 1 good start up with super offerings that would somehow be amazed by your average profile and offer you a position"
- "start ups are well, startups and may not offer a job security as strong as est. companies"
- "You are probably not as awesome dev as you think you are. for 2 years, you have only learned the concepts , and not launched more than 1 shitty app and a few open source work"
CHOICE 3: NON CODING
>>>>background: "companies coming in college placements have 1-2 rounds of aptitude,logical reasoning , analysis based questions and other non tech tests. There are also online tests available like elitmus,AMCAT, etc which, when cleared with good marks help receive placements from decent established companies like TCS, infosys, accenture,etc"
>>>>+ve points :
- "you will eventually get placed from college, or online tests"
- "there will be a job security, as most of these companies bonds the person for 2-3 years"
>>>> -ve points:
- "You really don't like this. These companies are low profile consultant/services based companies which would put you in any area: from testing to sales, and job offers are again $5000-6000 per annum at max"
- "Since it includes college, the other factors like your average cgpa and 1 backlog will play an opposing role"
- "Again, you are a 70 percentile avg guy. who knows you might not able to crack even these simple tests"
Ugh... I am fucking confused. Please be me, and help.The things that i wrote about myself are true, but the things that i assumed about super companies, start ups or low profile companies might not be correct, these points comes from my limited knowledge ,terrified and confused brain, after all.
Hi everyone! I'm in need of some help regarding the approach to my bachelor thesis.
The practical stuff is basically clickstream/task and usability analysis on an existing platform and creating mockup improvements for some processes. I was thinking about using a spider to generate a tree (or another datastructure) regarding all the different tasks available and then trying to optimise said tree, thus automatically optimising the processes within. I'm having however issues imagining how this optimisation might be generalised for more than this one platform.
Basically, I'm a bit lost and grasping for any pointers in any direction regarding these ideas.3
I created a sample project while I was an intern to help me and my teammates analysis everything going on with an app very handy. I wasn't assigned to the task but I worked after office hours to complete it. I worked so much after it and very few people appreciated it.
Now after three years, when I'm a team-lead and we suddenly got this requirement from our client same as I worked on internship, I cried of happiness.
Nothing goes in vein. Everything you work with your heart helps you some or the other way.
Top 12 C# Programming Tips & Tricks
Programming can be described as the process which leads a computing problem from its original formulation, to an executable computer program. This process involves activities such as developing understanding, analysis, generating algorithms, verification of essentials of algorithms - including their accuracy and resources utilization - and coding of algorithms in the proposed programming language. The source code can be written in one or more programming languages. The purpose of programming is to find a series of instructions that can automate solving of specific problems, or performing a particular task. Programming needs competence in various subjects including formal logic, understanding the application, and specialized algorithms.
1. Write Unit Test for Non-Public Methods
Many developers do not write unit test methods for non-public assemblies. This is because they are invisible to the test project. C# enables one to enhance visibility between the assembly internals and other assemblies. The trick is to include //Make the internals visible to the test assembly [assembly: InternalsVisibleTo("MyTestAssembly")] in the AssemblyInfo.cs file.
Many developers build a POCO class in order to return multiple values from a method. Tuples are initiated in .NET Framework 4.0.
3. Do not bother with Temporary Collections, Use Yield instead
A temporary list that holds salvaged and returned items may be created when developers want to pick items from a collection.
In order to prevent the temporary collection from being used, developers can use yield. Yield gives out results according to the result set enumeration.
Developers also have the option of using LINQ.
4. Making a retirement announcement
Developers who own re-distributable components and probably want to detract a method in the near future, can embellish it with the outdated feature to connect it with the clients
[Obsolete("This method will be deprecated soon. You could use XYZ alternatively.")]
Upon compilation, a client gets a warning upon with the message. To fail a client build that is using the detracted method, pass the additional Boolean parameter as True.
[Obsolete("This method is deprecated. You could use XYZ alternatively.", true)]
5. Deferred Execution While Writing LINQ Queries
When a LINQ query is written in .NET, it can only perform the query when the LINQ result is approached. The occurrence of LINQ is known as deferred execution. Developers should understand that in every result set approach, the query gets executed over and over. In order to prevent a repetition of the execution, change the LINQ result to List after execution. Below is an example
public void MyComponentLegacyMethod(List<int> masterCollection)
6. Explicit keyword conversions for business entities
Utilize the explicit keyword to describe the alteration of one business entity to another. The alteration method is conjured once the alteration is applied in code
7. Absorbing the Exact Stack Trace
In the catch block of a C# program, if an exception is thrown as shown below and probably a fault has occurred in the method ConnectDatabase, the thrown exception stack trace only indicates the fault has happened in the method RunDataOperation
8. Enum Flags Attribute
Using flags attribute to decorate the enum in C# enables it as bit fields. This enables developers to collect the enum values. One can use the following C# code.
he output for this code will be “BlackMamba, CottonMouth, Wiper”. When the flags attribute is removed, the output will remain 14.
9. Implementing the Base Type for a Generic Type
When developers want to enforce the generic type provided in a generic class such that it will be able to inherit from a particular interface
10. Using Property as IEnumerable doesn’t make it Read-only
When an IEnumerable property gets exposed in a created class
This code modifies the list and gives it a new name. In order to avoid this, add AsReadOnly as opposed to AsEnumerable.
11. Data Type Conversion
More often than not, developers have to alter data types for different reasons. For example, converting a set value decimal variable to an int or Integer
Hi So I need some solid advice from you all wonderful people.
I think i am now ready to look into job side of this world, but have lots of doubts , read my story.
I have been learning android for last 2 years. Most of the time i have been trying to understand how stuff works in android , but i have also gained a few other skills ( python programming, kotlin/flutter basics data analysis basics, testing, some graphic designing, aweful web dev ,etc). But i really want to work with Android. I don't have any specific Salary figure in mind, but i guess my knowledge is better or atleast par with most of the good android developers.
So i want to know how is this fresher/placement thingy work?
1.) GETTING KNOWN? : How can i make some good android based company aware that I am available for hiring? Should i start emailing every android related company that i know of? Should i start listing my profile on recruitment sites like linkedin or internshala? This year it is being said that companies will come for placements. From the status of my college, they are going to give me way to less $ , nd i know am not going to like any of them, but i guess i have to sit for them too.
2.INTERVIEW OR DIRECT PLACEMENTS? A little pre-context: i am currently starting my 4th year in clg. Afaik , 4th year isnt that strict and their can be leniency in terms of attendance. But my college is a place full of political cun*s in the name of directors and HODs and I don't know if they are again going to enforce the old 75% mandatory criteria. Plus if the company is from a different state/country , then my attendance would definitely not suffice.
So mainly i am unsure if somehow a company hires me, i would be able to start immediately. I heard that there are interviews for job recruitment after which the candidate is binded with an agreement to do some months training followed by permanent working after college completion.
This type of agreement is very much suitable for me, since from what my friend tells me, trainings can be lenient and understanding regarding exam preparations nd stuff.
So what do company usually chooses? Binding a fresher on immediate working basis or do they consider graduate completion?
Also, i suck at competitive coding. Do i need to polish myself on that or some company is willing to give me chance on the basis of my other skills 🙈(okay, no kidding , that's a serious question. I need to either work on getting better in competitive or build more apps based on that)
3.) ANDROID OR EVERYTHING? From what i have heard, working as a professional fresher is more like being an allrounder than being a domain specialist. But as i already stated, i really dig android and that's no small framework. I may di other stuff too, but won't interest me nd my output might be less efficient than expected.
So freshers can really be asked to do any stuff? Or can i still be in the area i like being into?
4.) COMPANY OR START-UP? Yeah, this is a general debate starter. Ignoring the business side of the conversation ( job safety vs more salary, experience, etc) the thing that's most important for me is the presence of a team. I want someone to assign me a task, whose vision i could follow, from whom i could learn, and some other people who are supportive and doing the same amount / similar work that am doing . This is so much import8 for me that i can easily ignore other factors for a better team. I once took a call from a startup ceo who hired me, a 2 month old android beginner at that time, as the "lead android developer"
But if am being on a team where i am supposed to do any random stuff that is assigned, then obviously this whole point of "visionary, helpful leader, guiding team, "etc goes moot9
