Recenty I have studied a lot about Bitcoin and Blockchain. The technology behind these things is amazing. And people are going mad over it. But, are we really going to the right direction? I have doubts.

Bitcoin was targeted to be a decentralized system. But in the present scenario, if BTC.com, AntPool and ViaBtc somehow merge, they will own more than 51% of the total computational power of the Bitcoin network. And if that happens, they will have full control over the whole network and will be able to replace the whole Bitcoin Blockchain with their forged entries if they want. By the way, btc.com is China based and owns 29.6% of the total computational power of the Bitcoin mining network. Forget about merging, if btc.com grows independently, who can assure that they would never cross the 51% threshold? Same problem exists with other Blockchain systems too. Are these systems really decentralized as they advertise? I really doubt now.

In the Global Blockchain Congress currently taking place in Kolkata, India, 'IT' officials from PWC India and IBM India start their speaks right after a popular cryptography professor from Belgium and a Blockchain entrepreneur from Brazil.

Every word these 'IT officials' uttered showed how shallow and business minded the IT managers and marketers are.

Hello fellow Devs,

I have developed a small Android library for handling HTTP POST and GET requests. Anyone who is looking for an easy way to perform HTTP calls, can use this library. It supports post requests with JSON and Multipart Form data, file uploading and Get request with URL parameters.

Hope it will help you guys.

I have been working on IoT projects for last five years. After using MQTT in many of my projects I have realized that there is a huge learning curve for the beginners to understand and implement MQTT in their projects. The packet structure of MQTT is complex and MQTT packets are difficult to debug. Also customizing the open source MQTT brokers are also difficult for the beginners, and sometimes even for the experts.

To make IoT and Messaging simple, I am designing a new protocol which uses JSON packets for data exchange and is far less complex than MQTT. I am also developing an open source project which will contain a server (with load balancer support), a python client, a Javascript client and a python based load balancer. I hope this project will reduce the development time as the protocol is easy to understand and the open source code is fully modular & easy to customize.

This will be my very first contribution to the open source community. Wish me luck!

I started my career 7 years back (at the same company I am currently working) as an Asp.net developer. My company used to work in Microsoft domains back then. 5 years back one of our directors decided to dig into the open-source technologies and move away from Microsoft. And I was the first employee who was assigned to learn python. I thought about switching the company so that my 2 years of asp.net experience doesn't go waste. But I didn't as I started liking python. It was easy, powerful, clean, and same code ran on every fucking platform. And I was introduced to open-source.

Don't know best or worst, but this decision definitely changed my view about software development. I understood that money is not everything, passion is also important. The open-source community runs on passion and dedication. And I love the way it works. The bottom line is, I am happy. And python is beautiful.

I am working on a project which I want to make open source. The problem is, I have never launched any open source project and I do not know any platform to reach people (I am not talking about hosting the project, I am talking about making people know, use and take part in the project). I believe this project will help a lot of people who works on IoT, chat services or distributed real time servers.

Can anyone help? Thanks in advance.

Ubuntu users in the floor, it's time to be proud 😂

I like iOS human interface design much more than the Android's material design, though I am an Android user. It has some unimportant design components IMO. I feel that the default action bar title is too big. Also that floating action button is weird sometimes. It hides some important portion of the contents in poorly designed apps.

**phone rings**
- Hello
- Hi. I am calling from *some MNC*. We have a job opportunity for you. Do you have any plans to switch?
- What's the domain?
- It's asp.net and Xamarin.
- Sorry, I do not work on that anymore. Please let me know if you have any openings in Python.

**phone rings again**
- Hello
- Hi. I am calling from *another MNC*. We have a job opportunity for you. Do you have any plans to switch?
- What's the domain?
- It's python.
- Sorry, I do not work on that anymore. Please let me know if you have any openings in asp.net.

My story for last four years. I guess I have found the most humble way to reject the job calls.

I was thinking my Android Studio is broken 😂😂

I am working on a pub-sub based protocol (like MQTT) with some added features. I am developing a python based server for my protocol which can be run on distributed architecture with load balancing without any tweaks. I am planning to make this server and the protocol open source.

The whole thing is getting so complex that I think about scrapping this project sometimes. I need your inspiration guys. Really, I need it. I know this protocol will be good enough to help people working on IoT, chat or any pub-sub based application if I can complete it. Cheer me up, please.

I work in a small scale company based on Kolkata, India. It's my first job and I have been working here for last 6 and half years. Now I am the technical lead there.

I love my job. I love taking new challenges which I need to solve on my own (most of the times). My working hours are 9am to 6pm. Hardly I have to stay late at office. Even if I have any client meeting after 6, I do it from home. I am never tired on Mondays, I love to join my office. I can do my personal projects after reaching home, sometimes even in the office. All these goods come with a small price, I get less salary than my friends who are working on the MNCs (e.g. IBM, TCS, HP etc). They are frustrated though, with their jobs, with their bosses, with the long working hours. I am not. Sometimes I feel bad that I earn less. But that feeling doesn't stay much longer. It goes away whenever I join the office and get a new thing to do.

I have rejected offers from many companies. That includes all the major MNCs working in India. I feel bad about that sometimes, just like currently I am feeling. One my friend (a really bad developer) is roaming in the New York city, he is there for an onsite project. I know I can't go their, at least now. And that feels bad.

What should I do? Does it make me an idiot to stay in a company for more than 6 years? Should I switch and join an MNC like everyone does? I am confused. Pretty confused.

Python3's asyncio is awesome.

In an IoT server we used python2 socket programming with multi-threading. Recently I have changed the socket layer to python 3 asyncio and performance was far better. I am not gonna use multi-threading anymore.

What do you guys think about asyncio?

In a recent venture, I had to use an office suite and a photo editing software regularly. As a Linux user, I tried using Libreoffice and gimp. But that was just a mess. My other project partners were using MS office. Format, image alignments, fonts.. everything was messed up. Same happened wih the gimp. I know Photoshop, learnt while studying. Gimp was just no match to that. I was forced to go back to Windows. And I was surprised that the latest MS office and Adobe Creative Cloud were excellent. MS office was smoother and faster than Libreoffice.

I love linux. I have tried all the major distros and I love all of them. But I would still say that Linux is not the best option for day to day non-dev tasks. Whatever Richard Stallman and the Open Source Community say, Linux lack good softwares, at least some good document, photo, audio and video editing softwares.

The IT head of my Client's company : You need to explain me what exactly you are doing in the backend and how the IOT devices are connected to the server. And the security protocol too.

Me : But it's already there in the design documents.

IT Head : I know, but I need more details as I need to give a presentation.

Me : (That's the point! You want me to be your teacher!) Okay. I will try.

IT Head : You have to.

Me : (Fuck you) Well, there are four separate servers - cache, db, socket and web. Each of the servers can be configured in a distributed way. You can put some load balancers and connect multiple servers of the same type to a particular load balancer. The database and cache servers need to replicated. The socket and http servers will subscribe to the cache server's updates. The IOT devices will be connected to the socket server via SSL and will publish the updates to a particular topic. The socket server will update the cache server and the http servers which are subscribed to that channel will receive the update notification. Then http server will forward the data to the web portals via web socket. The websockets will also work on SSL to provide security. The cache server also updates the database after a fixed interval.

This is how it works.

IT Head : Can you please give the presentation?

Me : (Fuck you asshole! Now die thinking about this architecture) Nope. I am really busy.

Recently my company has bought a patented product from the IIT, Kharagpur, India (those who are not from India just Google this name. It's one of the most esteemed engineering colleges in India). I can not provide the details of the product, but let's talk about the technology stack they used.

The software module of this product was built using VB 6 (yes, you read that right) and MATLAB 6.0 (released in 2000), and used MS Access for database. Remember, the product was built in 2015 and patented in 2016 or 17. The people who built the software were mostly final year B.Tech CS (equivalent to B.S.) students and one IIT professor.

This shows what we need to change in the CS education. Do I need to say more?

Usually I develop in python, mongo, cordova and node. Few days back I installed Windows on my laptop cause I needed to use the Visual Studio for a specific task. Then I thought that if I can setup the python, mongo, cordova and node stack on Windows then I don't need to switch between Linux and Windows frequently. And that was a horrible decision.

It took almost 8-10 hours to setup that shit, and still I couldn't make it work. There are so much complexities and those do not make any fucking sense! I mean why the hell I need to add the python path to the environment variables, and then again add the pip path separately. Then mongodb can not autostart. And finally I needed to make and build a package, and that waa the moment when I just scrapped it.

It takes me 2-3 hours to setup a fresh Linux box (which supports apt) including the OS installation. Same for the osX. I still wonder that why Microsoft does this! If Windows is for non-dev and non-tech people then why don't they release a Windows developer edition? Developing anything except ASP.NET and Java in Windows is a fucking nightmare for me!

Want to start a open source project, but don't know what to start with. Specially don't know how to involve people or share the idea. Any help?

Today I have created a server application on Python Tornado which can forward TCP Packets directly to HTTP request queue without any intermediate caching.

Our remote IOT devices (microcontrollers with sensors attached) send sensor reading over TCP Socket to our server and all the connected web applications can show the data instantly using long polling and the above mentioned technique.

I can play with this little guy all day long.

Why most of the Indian developers code so bad? I face it very often, with my colleagues, with the freelancers we hire, even with our clients.

I am an Indian, and I feel so much disgusted (& sad as well) when a client tell us that they have a dedicated team to rework on the code which they outsource from India. If you visit a freelancing website you will see that the Indian developers have the least price, and they bid on literally anything even without understanding what they need to do. And finally when they get a job, they complete it, but with a fully f*cked up code and the worst architecture possible.

I have a lot of friends working in IT, and I personally know that they do not have any passion about programming. They just work for money, nothing else. I don't understand, why? My 7 years of IT career is probably not long enough to find a suitable answer for this 'why'.

Anyone who knows or works on cryptography? Need a little help

MQTT - all I used to know about this is its name, untill few months back a client sent us some requirements which included MQTT. I opened its specification and I was fucking shocked! I am implementing almost similar protocol in most of my applications (which needs subscription based service) for last 3 years. I have developed IoT apps, remote monitoring systems, HMI systems using the same fucking protocol! Even I had implemented the same thing on HTTP using long polling a few years back!!

Now I feel like open sourcing my protocol. But I don't know where to start. Any help please?

I want to build up a team of developers for my new project. I always have done solo projects. And I don't want to involve my colleagues. I need to find some people whom I can work together. But don't know about any proper place to where I can go to find them.

Can someone help me with this?

I use Mac in office for daily dev and tasks, and a Lubuntu laptop for Linux related jobs. My home PC runs Ubuntu. And my personal laptop has a Ubuntu-Windows dual boot. I haven't used the Windows for more than a year. Even I do most of the basic tasks in Terminal, both in Mac and Linux.

Now I need to install a custom ROM in my Android Snapdragon based phone. And all the tools I need runs in Windows only. I don't even want to open that boot partition. 😥

Any help on this? It would be better if I can get something which runs on Linux.

So here's the deal. I am a team lead of a small company and I have a junior who is an idiot. I mean literally, idiot. We code in Python mostly and as Python is not structured as a default Java or C# project, the developer needs to be very careful so that the structure (or tiers) is maintained properly.

Now this girl, always messes up the tiers. Say one enhancement can be easily implemented in the UI tier, she would do the implementation in the core Db access layer, which may complete this particular enhancement, but breaks all the other functions (sometimes the whole project) connected to that particular module of the Db layer. She doesn't do any integration testing after updating the code, she only checks the current enhancement she is working on. When the enhancement goes to the testing phase, the testers find those broken functions and that results a re-work (most of the times done by me).

I have warned her. Even our manager has warned her. She always tells that she is working to improve herself. But I know, she isn't. She mostly chats with her boyfriends (yes, with an 's') when she has no work to do. She never upgrades herself or works on her skills.

I can easily report about her, and they will fire her without any warning (they did it already with a guy earlier). I don't want to do that again. What should I do? Any suggestions?

Oh, she has a great ego. She thinks that knows and understands everything. She will listen to your suggestions carefully, but will never follow those.
