There are three different ways to optimize a website for mobile devices: Responsive design Responsive design is probably the most popular choice, and olen the easiest to implement (but it helps if it's implemented from the get-go and not as an afterthought). It uses CSS media queries Apps And Mobile Advertising to specify different styles for different situation, such as small screens (like on mobile devices). Basically, it's telling the browser to use these styles if the screen is smaller than 960px, and these other styles if the screen is smaller than 640px The HTML remains the same whether the user is mobile or not. Dynamic Serving With dynamic serving, mobile users are served separate content transparently. The server tries to detect if the visitor uses a mobile device, and serves them separate HTML/CSS suited for their screen. The downside of this approach is that the device detection needs to be flawless (which it ojen isnt), or the visitor may ...

Ask HN: How can I work towards building a company while employed? 392 by mr_puzzled | 179 comments on Hacker News. I will start a job as a software dev and with the job offer comes a bunch of contract clauses that basically lets the company own all IP while employed. I am from a third world country, so I won't be able alter the contract clauses. With these restrictions in place, what can I do while employed to have a better chance of succeeding when I do start a company? My plan : - continue learning while on the job - prepare for interviews so that I can apply to companies that are friendly to side projects (stripe, gitlab, github and a bunch of other such companies. Please mention companies that are ok with remote workers and are side project friendly, even startups paying $30,000 work for me) - build side projects in my free time that demonstrate my skills - maybe participate in Pioneer.app tournaments so I can network - basically work on stuff that won't become a company...

I can see your local web servers 425 by jamesfisher | 137 comments on Hacker News.

Apps and Mobile Advertising A mobile marketing strategy doesn't stop at just optimizing your website for mobile visitors though. Depending on your business, you may also want to consider building an app and using mobile advertising platforms to reach your customers where they spend a lot of their time. These days it might seem like everyone has their own app, but it's for a good reason: a study by Compuware found that 85% of mobile users prefer apps over mobile web browsing. Most likely this is because apps offer a lot more creative freedom and advanced features than simple web pages can, mobile optimized or not. The shift from web browsing to apps is also one of the major forces that are driving much of the mobile advertising market, which is absolutely booming as shown in the study from eMarketer. From having previously been neglected by many because the consensus was that mobile users had very little commercial worth, it is now starting to gain ser...

Scrum is fragile, not Agile 449 by pplonski86 | 267 comments on Hacker News.

Introduction : All the requirements for the system should be included in a clear and concise document.  For this, it is necessary to organize the documents of requirements in the form of sections and subdivisions.  There are several ways to structure the requirements documents.  Several ways and standards have been proposed for organizing SRS.  One of the main ideas to standardize the structure of the document is that with the available standard, each SRS will fit a certain pattern, making it easier for others to understand (this is one of the roles of any standard).  Another role in playing these standards is that, when there is a need to specify different aspects, they help in ensuring that analysts do not forget some of the major assets.   The IEEE standard recognizes the fact that their requirements may be required to organize different projects individually, that is, there is no such method which is suitable for all projects.  It provides diffe...

Introduction: - Requirements specification requires the use of some specification language.  Language should support the desirable qualities of SRS - variability, understanding, unambiguous, and so forth.  Apart from this, learning and using languages ​​should be easy.  As no one can expect, many of these characteristics in the specification language selection conflict.  For example, to avoid ambiguity, it is best to use some formal language.  But a natural language can be better for ease of understanding.   Although formal notifications are available to specify the specific properties of the system, natural languages ​​are now often used for specific requirements.  If formal languages ​​are to be used, they are often used to specify special qualities or specific parts of the system, and these formal specifications are usually contained in the overall SRS, which is in a natural language.  .  In other words, the overall SRS is usually in a ...

Having rules about what various things a SRS ought to indicate will help in totally determining the prerequisites. SRS must address are: • Usefulness • Execution • Plan requirements forced on a usage • Outside interfaces Thoughtfully, any SRS ought to have these parts. On the off chance that the conventional way to deal with necessity examination is being pursued, at that point the SRS may even have divides relating to these. Be that as it may, practical prerequisites may be indicated by implication by determining the administrations on the articles or by indicating the utilization cases. Useful Prerequisites :- Useful necessities determine which yields ought to be delivered from the given sources of info. They portray the connection between the information and yield of the framework. For each utilitarian prerequisite, a point by point depiction of the considerable number ...

H.264 is Magic (2016) 436 by dpeck | 124 comments on Hacker News.

Introduction: - The original goal, one SRS should have some qualities and different needs should be there.  Desirable features of components of SRS and SRS.   A good SRS-   1. Correct   2. Complete   3. Undoubtedly   4. Verifiable   5. Compatible   6. Rank for importance and / or stability   7. Convertible   8. Following   An SRS is correct   An SRS is completed if the software has to do everything and SRS software responses are specified for all sections of input data.  Purity and perfection go hand in hand;  While purity ensures that what is specified is done correctly, perfection ensures that everything is actually specified.  Correction is an easy asset to set up completely because it involves checking essentially every requirement in order to ensure that it represents the user's requirement.  On the other hand, perfection is the most difficult asset to install;  To ensure com...

Introduction: - The final production software requirements specification documents (SRS).  For small problems or problems that can be easily understood;  After complete analysis, specification activity can occur.  However, an analyst will usually analyze parts of the problem and then write the requirements of that part.  In practice, problem analysis and specification of requirements overlap activities, with movement in both activities from one to another.   The first question is, if formal modeling is done during the analysis, then why are the outputs of modeling - the structures that are manufactured - are not considered as SRS?  The main reason is that modeling is usually focused on problem structure, not on its external behavior.  As a result, things like the user interface are rarely modeled, while they often make a major component of SRS.  Similarly, for ease of modeling, often incorrect situations such as "minor issues" are hardly modele...

Introduction: In comparison to modeling-based approaches, prototyping takes a different approach to problem analysis.  In prototyping, a partial system is built, which is then used by clients, users and developers to gain a better understanding of the problems and needs.  Therefore, the real experience with a prototype that implements part of the final software system, is used to analyze the problem and understand the requirements of the final software system.  A software prototype can be defined as a partial implementation of a system that aims to learn something about the solution or the solution approach to the problem.   Prototype can also be used to evaluate or evaluate a design option.  Here we focus primarily on the prototype used to understand requirements.  There are two approaches to the prototype;  Tiresome and evolutionary   In Throwaway approach the prototype is constructed with the idea that after completion of the analysis, it w...

U.S. Farmers Are Being Bled by the Tractor Monopoly 425 by jelliclesfarm | 321 comments on Hacker News.

Introduction: In object-oriented modeling, a system is seen as a set of objects.  Objects interact with each other through the services they provide.  Some objects also interact with users through their services so that users can get the desired services.  Therefore, the purpose of modeling is to identify the objects present in the problem area, by defining the class to define the class of which they enclose the information of which state and what services they provide, and relationships between the objects of different classes  Identifies, such as the overall model.  It is such that it supports the desired user services.   Object-oriented modeling and systems are being given a lot of attention in recent times.  The root cause of this is the belief that Object Oriented systems are going to be easy to build and maintain.  It is also believed that object-oriented analysis will be easy to transition into object-oriented design (and implementation)...

Ask HN: What overlooked class of tools should a self-taught programmer look into 608 by nathanasmith | 280 comments on Hacker News. 15 years ago I learned Python by studying some O'Reilly books and I have been a hobbyist programmer ever since. The books went into detail and since reading them I've felt confident writing scripts I needed to scratch an itch. Over time, I grew comfortable believing I had a strong grasp of the practical details and anything I hadn't seen was likely either minor quibble, domain specific, or impractically theoretic. This was until last year when I started working on a trading bot. I felt there should be two distinct parts to the bot, one script getting data then passing that data along to the other script for action. This seemed correct as later I might want multiple scripts serving both roles and passing data all around. Realizing the scripts would need to communicate over a network with minimal latency, I considered named pipes, Unix domain ...

Presentation: - Information stream based demonstrating, frequently alluded to as the organized examination strategy, utilizes work based deterioration while displaying the issue. It centers around the capacities performed in the issue area and the information expended and created by these capacities. It is a top-down refinement approach, which was initially called organized investigation and particular, and was proposed for creating the determinations. Information Stream Charts and Information Lexicon Information stream charts (additionally called information stream diagrams) are normally utilized duringproblem examination. Information stream outlines (DFDs) are very broad and are notlimited to issue examination for programming necessities detail. Theywere being used some time before the product building discipline started. DFDs arevery valuable in understanding a framework and can be viably utilized duringanalysis. A DFD demonstrates the progression of information through a fra...

Introduction: The informal approach to analysis is that where no defined method is used.  Like any approach, information about the system is obtained through the client, end users, questionnaires, study of existing documents, thought-churning etc.  However, no formal model system is built with this approach.  Problems and system models are essentially made up of analysts (or analysts can use some informal notation for this purpose) and are analyzed directly from the minds of analysts in SRS.   Often, with such an approach, the analyst will have a series of meetings with customers and end users.  In the initial meetings, the client and the end user will explain to the analyst about their work, their environment and their needs, as they understand them.  Any document describing the work or organization can be given with the output of existing methods of performing tasks.  In these early meetings, analysts are basically listeners, absorb the informatio...

Introduction: The basic purpose of problem analysis is to get a clear understanding of the clients' and then the information of the users that what is really desired from the software, and what constraints on the solution.  Often customers and users do not understand or know all their needs, because the ability of the new system is not often fully appreciated.  Analysts must ensure that the real needs of the customers and the users are highlighted, even if they do not know them clearly.  That is, the analyst not only collects and organizes information about the organization and its processes, but also acts as an advisor who plays an active role in helping identify the needs of customers and users.  .   The basic principle used in the analysis is similar to any complex work: split and win.  That is, split the problem into sub-problems and then try to understand every subtype and its connection to other sub-problems in an effort to understand the total pro...
