When i read your post and tried to create a ECS account, it struck me that the issue could be related to a firewall that blocks the FTP/HTTP requests. Here is a user complaining of a similar issue. https://www.alibabacloud.com/forum/read-159

Are you a developing an Android App and require to know the minimum support version on Android Studio ? The minimal support version of the Android OS that you select in Android Studio directly correlates to the Version of Android API on an Android Phone. The API version controls what functionalities (as provided for by the API) are available on an Android device. https://en.wikipedia.org/wiki/Android_version_history While developing an App, selecting a version of Android (eg 7.0 is Android Nougat) enables you to use functionalities (upto API level 24 in Android Nougat) for your App development. The downside, logically is that an app developed for Android Nougat with API level 24 will not deploy on an Android device whose OS version is < 7. Hence the reason why in the Android App config, you have to select a minimum version of the API so that your app can be deployed on devices that were shipped with an earlier Android OS version (Kitkat - API 19-20, Lollipop API 21-22). Once you select an Android Version as minimal support version , you also need to download the corresponding SDK platform and build tools for that version. One hack for testing purposes is to change the minSDKVersion in your App Config (build.gradle) and deploy the app on a android device with a earlier legacy version of Android like JellyBean (Version 4.x API Level 16) or Kitkat (Version 4.x API 19-20) to see if your code base will build for older devices.

When i read your title, i thought you were asking for a tool like Sketch UP , where you can create (not make) a software and then load it on a viewer (ViewUP) elsewhere. How can i make a software that load 3d object and can manipulate it? Looking at your explanation, I think your question is about individual graphics formats like Maya, and how to create a 3d Modelling tool (a basic version). You need to do a bit of research on existing (open) 3d format. From what i just now searched 3d ' standards ' are a diverse topic in itself. If you are aiming to create something for a college project or a simple prototype , i would urge you to look at WebGL. Note - For practical purposes, nobody would want to create their own 3D modelling tool, because of the sheer amount of work it is, and the commercials cannot justify it when there are excellent 3d modelling tools ( freeware and proprietary) available to do the job for you. 3D modelling tools are not developed by individuals but institutions that also play a significant role in defining the computing standards based on industry requirements, which has paved the way for the development of industry specific modelling and simulation environments, ( Simulink, Matlab, AutoDesk Maya, 3DStudio Max, Blender and many others ) offering 3d modelling capabilities. Developing a full fledged 3D modelling tool requires a comprehensive understanding of GPU programming and OpenGL ( the hardware implemented state machine) that all Graphic APIs use to create graphics, particularly 3d. You should also take a look at this brief on CUDA , and the associated docs for GPU programming . There are higher level libraries that one can use to generate 3d Graphics . Learn Open GL is my favourite site to introduce beginners to the subject.

Sketchup is great for making 3d models and publishing to the cloud. You can use the ViewUp app to check your 3d models on your smartphone device.

Building relationships is an extremely difficult aspect at organizations, but its always based on Trust. Ive been trying to enlist people to work with me on Java, Perl, Game Dev projects for 3-4 years now and i realize that Trust is the single most important factor when it comes to building relationships. The few ones that still show interest in working with me i am extremely patient with . Their failure to deliver as per my expectations often goes unnoticed on the outside, as i realize that the Trust that i have in their person outweighs the dissatisfaction of the project not moving at the speed i wish to. If i sense i cant Trust a person, then within a moments notice i am showing them out of the door, albeit extremely politely, citing our interests dont match, or i do the "its not you its me routine :D"

Well if you are the highly irritable kind, and a consummate techie , then i suggest explaining to people (higher ups you trust) that you are facing problem entering .NET stream . Seek an assurance (written) that once this activity is done, you can go back to developing apps in android and kotlin. It is always good to have mentors in an organization who are non-technical so that their perspective enables you to perform better, and rise higher in the organization. But agreed that Kotlin and .NET are two different streams, and you should be careful about which project you are putting your heart and soul into. At the end of the day in IT companies, techies are 'resources', and due to staffing compulsions, asking a developer to cross-skill into another area of technology is not an alien concept. The larger (and more professional ) the company , the lesser the likelihood of such a cross-skilling activity being planned, though i can tell you that market needs and industry compulsions, are strong drivers that can influence even the best of organizations towards cross-skilling its employees.

I just discovered Bounty Source via searching for a missing feature for a terminal based Twitter Client. This website seems to have a good list of features/ bugs that need to be developed/fixed for open source projects, and you can find some interesting pro-bono work there for a start.

I dont think you need to go far as implementation details and compiler design to know if they are technically job-worthy. My opinion was - Assuming the position is for a Python programming beginner, they must have sound knowledge of the difference between an interpreter and a compiler So a question would be What is the difference between a compiler and a interpreter ? This level of knowledge in my opinion is a must if you are interested in the science that drives Programming Languages and not merely having a superficial interest in Python . Implementation details are more for the advanced Programmer, who has interest in the internals of the language. Compiler Design fundamentals are not an area i would ask even an advanced Programmer in a job interview, unless i am asking him to join me on a Compiler Design project .

Programming is a Science,and the Programming Language in question becomes an implementation of such a Science. Assuming the position is for a Python programming beginner, they must have sound knowledge of the difference between an interpreter and a compiler, and you should also throw in a question of how Java works , since it brings in the concept of byte code based virtual machines. I myself am a Perl programmer learning Python, so the first thing i try to learn as a Python programmer is how its data structures are implemented. The key , in my opinion , to learning the nuances of a language, is a thorough understanding of its data structures(arrays, hashes, trees) , and hence by necessity its data types. Concepts likes OOPS, and classes, are programming language independent, but based on the need of the project, one can always throw in a few questions to ascertain their knowledge of how Classes, Objects are represented in the language, and their degree of proficiency can also be gauged by nuances like how is poly morphism implemented ,and how basic memory management is done in the language. As a Javascript programmer, a basic understanding of the DOM is a backbone to being a good JS programmer. By current web programming standards , there is an over dependence on Jquery and other libraries, so one can indulge JS programmers on key questions of writing performant, secure code that they need to be aware of. Good debugging skills are essential for any JS programmer, as unlike Java it is not an easy language to quickly understand others code. So if you are tasked with being a JS programmer in an organization, you must be able to debug code yourself and figure out constructive solutions to problems you / others are facing.

"and its intended to serve small businesses in accounting" Are you trying to therefore create a General Ledger , that will enable small businesses to do their accounting online. First step is to check how existing accounting softwares are 'modelled'. There are industry standards for UML / Entity Relationship Modelling which are implemented from the ground up by the Enterprise Companies like Oracle and SAP. Research the Data Model for Oracle Financials , which should be based on the Industry Standard. I am creating a Retail Tech solution from the ground up, and i am using the published ARTS data model from OMG as the data model,which is the industry standard for retail tech solutions including Oracle. Of course its a long road ahead, as the data model is ginormous,but i start by focussing on the core concepts in ER modelling, working up to the actual database schema. am thinking of implementing a single database that will track users and their linked database This is a nuance / feature of your solution and you can plan better in a bottom up manner, rather than the top down way that you are using to design your accounting solution. The point from an enterprise perspective is that its the Business Need that drives the innovation , the technology, and the implementation, not the other way around. To offer an on-demand Accounting Solution online to multiple customers, you have to check how existing solutions like SalesForce is built, and once you have a general understanding of the same, you can think of improvements / modifications.
