How to Install latest angular version

2019-06-14T01:21:00.002-07:00

Its pretty much easy and here's a list of steps for a beginner:

Install latest nodeJS from https://nodejs.org/en/download/
Incase if nodeJS is already installed then update your npm with command "npm update"
Install the latest angular-cli on global level using command "npm install -g @angular/cli@latest", This command is also required if you already have angular-cli older version installed, it will update it to the latest version for new project. As of now Angular 8.0.3 is the latest version.
Once you install the latest angular-cli then run "ng new your-project-name-goes-here" with what ever options you like. To know more about the available options list visit https://angular.io/cli/new

PHP Code for Web / Content Scraping

2016-10-31T08:24:00.002-07:00

Hi,

Today I am happy to share you a PHP code snippet / sample which scraps web content from website's far more faster then you think. Although this is just a sample, but you can code a awesome extension for your website or system which reads multiple website's in no time for new and better content.

Simple PHP Scraper
PHP has a DOMXpath function. I’m not going to explain how this function works, but with the script below you can easily scrape a list of URLs. Since it is PHP, use a cronjob to hourly, daily or weekly scrape the desired data. If you are not used to creating Xpath references, use Chrome plugin by selecting the data point and see the Xpath reference directly.

<?php
error_reporting(0);

$arr = array('URL_LINKS_GOES_HERE1','URL_LINKS_GOES_HERE2'); // insert list of URLs to scrape

echo "<table>";
foreach ($arr as &$value) {

$file = $DOCUMENT_ROOT. $value;
$doc = new DOMDocument();
$doc->loadHTMLFile($file);
$xpath = new DOMXpath($doc);

$elements = $xpath->query("XPATH_OF_CONTENT_ELEMENT"); // insert Xpath reference.
    
if (!is_null($elements)) {
 echo "<tr>";
 echo "<td>".$value."</td>";
  foreach ($elements as $element) {
 
 $nodes = $element->childNodes;
    foreach ($nodes as $node) {
      echo "<td>".$node->nodeValue. "</td>\n";
    }
 
  }
  echo "</tr>";
}

}
echo "</table>";
?>

Find the Nearest Number which ends with zero in JAVA

2016-03-17T23:05:00.000-07:00

Simplest Code:

// round it off to zero - Number ending from 1 to 9 will become zero.

int MyNumber = new Double(MyNumber / 10).intValue();
MyNumber = MyNumber * 10;

// Compile and Run to Test it out

public class toZero{

public static void main(String []args){
int MyNumber = 1556;

MyNumber = new Double(MyNumber / 10).intValue();
MyNumber = MyNumber * 10;

System.out.println(MyNumber);
}
}

Enable Column Sorting in a jtable - java

2016-03-08T20:31:00.002-08:00

Easiest way to enable sorting in a jtable in desktop java is write line of code

jTableObject.setAutoCreateRowSorter(true);

JSON and JAVASCRIPT differences and code difference

2016-01-18T02:25:00.003-08:00

Javascript Array:

var obj = [];

obj.push = 'Some VALUE'; Or var obj = ['SomeVALUE', 1, 2];

now to access them use obj[0] -- 0 stands the index No.

***********************************************

JSON Array and manipulations:

Example

var obj = { name : value, anotherName : anotherValue }; // if JS Variable used

var obj = { 'name' : 'value', 'anotherName' : 'anotherValue' }; // if JS Strings are used

Or Else

ips[ipId] = {};

ips[ipId]['name'] = value;

ips[ipId]['anotherName'] = anotherValue;

now -

JSON.stringify(object); // gets you the string of the JSON Object

// No need to parse, no need to use JSON.parse as the variable holds the JSON Object only.

if you want to create a JSON Object from string or reverse engineer JSON.stringify() Method then use JSON.parse();

Also, You can use string variables to specify the names of the properties:

var name = 'name'; // name is variable - changing its value often

obj[name] = value; // note that their are no single quotes near name variable;

name = 'anotherName';

obj[name] = anotherValue;a

Sublime Text Editor for Coders

2015-08-09T06:24:00.003-07:00

Sublime Text is a sophisticated text editor for code, markup and prose.
You'll love the slick user interface, extraordinary features and amazing performance.

Some things users love about Sublime Text

Goto Anything

Use Goto Anything to open files with only a few keystrokes, and instantly jump to symbols, lines or words.
Triggered with Ctrl+P, it is possible to:

Type part of a file name to open it.
Type @ to jump to symbols, # to search within the file, and : to go to a line number.

These shortcuts can be combined, so tp@rf may take you to a function read_file within a file text_parser.py. Similarly, tp:100 would take you to line 100 of the same file.

Multiple Selections

Make ten changes at the same time, not one change ten times. Multiple selections allow you to interactively change many lines at once, rename variables with ease, and manipulate files faster than ever.
Try pressing Ctrl+Shift+L to split the selection into lines and Ctrl+D to select the next occurrence of the selected word. To make multiple selections with the mouse, take a look at the Column Selection documentation.

Command Palette

The Command Palette holds infrequently used functionality, like sorting, changing the syntax and changing the indentation settings. With just a few keystrokes, you can search for what you want, without ever having to navigate through the menus or remember obscure key bindings.
Show the Command Palette with Ctrl+Shift+P.

Distraction Free Mode

When you need to focus, Distraction Free Mode is there to help you out. Distraction Free Mode is full screen, chrome free editing, with nothing but your text in the center of the screen. You can incrementally show elements of the UI, such as tabs and the find panel, as you need them.
You can enter Distraction Free Mode using the menu.

Split Editing

Get the most out of your wide screen monitor with split editing support. Edit files side by side, or edit two locations in the one file. You can edit with as many rows and columns as you wish.
Take advantage of multiple monitors by editing with multiple windows, and using multiple splits in each window.
Take a look at the menu for split editing options. To open multiple views into the one file, use the menu item.

Instant Project Switch

Projects in Sublime Text capture the full contents of the workspace, including modified and unsaved files. You can switch between projects in a manner similar to Goto Anything, and the switch is instant, with no save prompts - all your modifications will be restored next time the project is opened.

Plugin API

Sublime Text has a powerful, Python based plugin API. Along with the API, it comes with a built in Python console to interactively experiment in real time.

Customize Anything

Key Bindings, Menus, Snippets, Macros, Completions and more - just about everything in Sublime Text is customizable with simple JSON files. This system gives you flexibility as settings can be specified on a per-file type and per-project basis.

Cross Platform

Sublime Text is available for OS X, Windows and Linux. One license is all you need to use Sublime Text on every computer you own, no matter what operating system it uses.
Sublime Text uses a custom UI toolkit, optimized for speed and beauty, while taking advantage of native functionality on each platform.

6+ Reasons Why Authors Should Avoid GoDaddy

2015-06-04T23:01:00.002-07:00

There was a time when I had almost 40 domains with GoDaddy. I started using them ten years ago, back when GoDaddy was a new website with dungeon low prices.
Now I don’t own a single domain with GoDaddy.
Here are seven reasons why you should move away from GoDaddy:

#1 GoDaddy Has Terrible Support

I had one client who had constant trouble with her email because GoDaddy support constantly gave her wrong advice. She would have a small problem with her email and would call GoDaddy. By the end of the call her email would be totally broken.
Finally, she hired me to conference in with the GoDaddy representative and interrupt each time the GoDaddy rep would give her bad information. I had to interrupt a lot.
Update: GoDaddy has made some improvements in the last few years in the support arena. They offer better support than they used to. I don’t think this reason alone is reason to move away from them. But it is not the only reason to avoid GoDaddy.

#2 GoDaddy is Overpriced

GoDaddy lures customers in with prices that look low.
GoDaddy makes it look like .com domains cost $1.99 per year when in reality domains cost $10 for the first year and $15 for every year after that.
Price Comparison:

GoDaddy ($24.94/year)
- $14.99/year for Domain Renewal
- $2.95/year for Email Forwarding
- $7.00/year for WhoIs Protection
Na*********.com ($13.57/year)
- $10.69/year Domain Renewal
- $0.00/year Email Forwarding
- $2.88/year for WhoIs Protection

GoDaddy also charges you extra for things Na******** throws in for free, like landing page customization. Now these prices go on sale from time to time so your millage may vary. The key is to focus on the renewal price. Sale prices typically only apply to the first year.

#3 GoDaddy is Hard to Use

I cringe any time I hear a novice say they bought a domain on GoDaddy.
GoDaddy spends so much time trying to up-sell customers that it is hard to buy what you came to buy. If you don’t know what you are doing, you may find yourself paying for all sorts of things you don’t need. These added services can make your domain harder to use.
You have to be fairly savvy to use GoDaddy and not get ripped off.

#4 GoDaddy Hosting is Slow

iThemes, a major WordPress theme development company, blasted GoDaddy for overselling hosting space. GoDaddy puts thousands of websites on a single server. All those websites compete for server processing time and bandwidth. This causes the sites to run slow, especially if any of them are popular. The GoDaddy speed issues are exacerbated by the fact that Google now penalizes slow sites on its search results.
Not only is the hosting slow but making server changes is slow as well.
If you change the wrong thing you may not know anything is broken for thirty minutes and it may take another thirty minutes to “unchange” whatever it is you broke.

#5 GoDaddy Gives Too Little Control

Not only is GoDaddy slow but their server back end is difficult to use and limited. Instead of giving users an industry standard admin interface (like cPanel or Plesk), they give users a proprietary admin interface that is more interested in selling you more GoDaddy products than in giving you the tools you need.
This makes it harder (i.e. more expensive) to do simple things on GoDaddy.

#6 GoDaddy Uses Smut to Sell

Some people are more concerned about the moral degradation of our country than others. Many people feel the country is moving in the wrong direction. Let me just say that GoDaddy is no force for good in our culture. GoDaddy notoriously has the most offensive Super Bowl ads every year. Each year they submit ads that are deemed too inappropriate even for TV.
They then feature these “too hot for TV” ads on their homepage.
Even the ads that do get approved objectify woman’s bodies and degrade women into objects of lust for the purpose of making money. This is inappropriate, uncalled for, and not something conscientious people should support with their money. If we allow companies to manipulate our sexual desires to make a profit, how can we say we are any better than animals?
Authors can do better than GoDaddy.

#7 GoDaddy Backed SOPA & PIPA

GoDaddy backed one of the most destructive laws ever to threaten the internet. It was only after 50,000 GoDaddy users left in protest that they changed course.
While I applaud GoDaddy for finally coming out against SOPA, the fact is that we can’t trust them to protect the internet. It also shows us that if enough people transfer away from GoDaddy due to the offensive ads, that they might change course on that as well.

The Good News

You are not stuck with GoDaddy.
There are also a lot of better hosting providers.

Security considerations in websites

2014-08-19T10:19:00.000-07:00

Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption. Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of web development as a whole. Scripts can be used to exploit websites by granting unauthorized access to malicious users that try to collect information such as email addresses, passwords and protected content like credit card numbers.

Some of this is dependent on the server environment (most commonly Apache or Microsoft IIS) on which the scripting language, such as PHP, Ruby, Python, Perl or ASP is running, and therefore is not necessarily down to the web developer themselves to maintain. However, stringent testing of web applications before public release is encouraged to prevent such exploits from occurring. If some contact form is provided in a website it should include a captcha field in it which prevents computer programs from automatically filling forms and also mail spamming.
Keeping a web server safe from intrusion is often called Server Port Hardening. Many technologies come into play to keep information on the internet safe when it is transmitted from one location to another. For instance Secure Socket Layer Encryption (SSL) Certificates are issued by certificate authorities to help prevent internet fraud. Many developers often employ different forms of encryption when transmitting and storing sensitive information. A basic understanding of information technology security concerns is often part of a web developer's knowledge.
Because new security holes are found in web applications even after testing and launch, security patch updates are frequent for widely used applications. It is often the job of web developers to keep applications up to date as security patches are released and new security concerns are discovered.

Practical web development

2014-08-19T10:01:00.001-07:00

Basic

In practice, many web developers will have basic interdisciplinary skills / roles, including:

Graphic design / web design
Information architecture and copy-writing/copy-editing with web usability, accessibility and search engine optimization in mind

The above list is a simple website development hierarchy and can be extended to include all client side and server side aspects. It is still important to remember that web development is generally split up into client side coding, covering aspects such as the layout and design, and server side coding, which covers the website's functionality and back-end systems.

Advanced

Some more advanced web developers will also have these interdisciplinary skills / roles:

GUI (Graphic User Interface) design
Audio, Video and Animation processing and encoding (for web usage)
Flash Capabilities (animation, audio, video, scripting)
Web content management system Deployment and/or Content management infrastructure design, development and integration
Web applications development, integration and deployment
Web server stress testing (how much traffic can a web server running a specific application endure before collapsing)
Web site security analysis & testing
Web site code optimization (which is an important aspect of search engine optimization)
Project management, QA and other aspects common to IT development
Advanced customized admin panel (For end-users)
Database integration with web applications

Negative sides of the Zodiac Signs

2014-08-15T04:58:00.004-07:00

Don`t we all hide a certain aspect of our personality from the world? Nobody`s an angel and there is a wicked side to everyone.

Here`s revealing what your friend or lover will probably never ever tell you or even you will not tell anyone - the darkest and deepest secrets of the different sun signs

Aries
Most Arians tend to be chauvinistic, there is nobody who they think is worthy enough of even standing before them. Well, if that were true all the leaders of the world would be Aries. Their ego is bigger than the universe and dare you hurt it, you would have to deal with that vicious tongue of theirs that pierces straight through the heart. And last but not the least, they are insanely self-obsessed.

Taurus
The lazy bulls have this special quality about them that surely sets them a thousand miles apart from the rest and that is called avarice. Greed can drive them insane; they crave for all the luxury in the world but don`t want to work hard for it. Funny, isn`t it?

Gemini
Do you really think your Gemini friend listens when you share your problems with him/her? For one, they do not and even if they do, then all that we can say is God bless you. Geminis only know how to talk, they never listen. Well, only sometimes when they think the gossip to be juicy enough and at the blink of an eye they will be telling your most intimate secrets to everybody.

Cancer
The crabs are so nice that it hurts, but they do have a wicked side like everybody else, may be not as wicked though, and depends on how you look at it. They tend to be clingy and dependable, emotionally unstable and freak out at the silliest of things.

Leo
Now, how can a dangerous animal like Lion be nice? Proud and loud, Leos, just like their fire mates Aries, have a thing for being boisterous. Cross their line of fire and you`d be sorry you met them in the first place.

Virgo
Their sugar coated words should never be trusted. Beneath that calm and composed exterior is a cunning person who doesn`t really mean it when he/she says that they admire you. And yes, how can one forget about their knack for perfection or rather irritating need to poke their nose in every matter, whether it concerns them or not, all the time.

Libra
No the scales do not turn in their favour, not this time. Vanity conscious and power hungry, this air sign literally takes the symbol of their sign, the scales too seriously. They can be so finicky and obsessed about equality that it makes them go crazy.

Scorpio
You probably were expecting a lot of "good things" about the Scorpio and well, you wouldn`t be disappointed. There are actually a lot of good things that you didn`t know (or already knew) about them. Manipulative, selfish, controlling all that`s fine but the best thing is they never forgive. Revenge is a dish best served cold and the Scorpio out of all the signs understands it the best.

Sagittarius
The saying - "promises are meant to be broken" was probably by a Sagittarius. To a Sagittarian, life without adventure is so plain and boring that they need to do everything adventurous (read stupid) to get their adrenaline pumping, even if it means breaking someone`s heart (but they do realize it later).

Capricorn
Goats and devilish? You`d probably say no way but here`s letting you on a little secret-they are selfish, very selfish indeed. One has to give it to the Capricorns for maintaining such a saintly image.

Aquarius
Aquarians have a deep desire for fame and they will do anything for it. Being detached is one thing and backstabbing is another but to an Aquarian they are all the same. They do so unintentionally though, if that is any consolation.

Pisces
Round and round the fish goes, planning the next best move to get what it wants. Sweet on the outside and "God knows what" on the inside, Pisceans can be really deceptive and manipulative. A grown up Piscean may even cry or bawl like a kid to get what he wants.

DON'T MISS The Right Job for Zodiac signs

2014-08-15T04:57:00.004-07:00

There are no right or wrong people or right or wrong jobs. This situation is more like the right people stuck with the wrong career option, or the wrong people taken for the right job. So, how will we deal with this confusion? Let`s take a look at what astrology has to say about this. Let your zodiac sign help you guide your career path. You never know, you might just make the most of it, starting today!

Aries:

Aries make great artists and sportsmen. People of this sign cannot take too much of interference with their work. These guys make great researchers, scientists and engineers too. They like to work at their pace and in their style. No, that doesn`t mean they can`t take orders, but try letting them be on their own and they`ll come up with the best results!

Taurus:

Taureans are creative souls. They have a taste for art and are talented entertainers. These guys cannot go by the hardcore corporate rules. They find it hard to breathe in a dishonest environment. Being great money managers, banking and accounting jobs are also great career options for them.

Gemini:

Geminis make outstanding journalists. Due to their innate nosy nature, these people fit perfectly in this profession. A Gemini person has strong verbal skills; a talk show host is a great option too! Translators, Public Relations, company HR and other such professions are more suitable for this bunch.

Cancer:

Cancerians can find their perfect stop as a judge or a lawyer. With their perfect sense of judgment, and ability to not let wrong happen, these people will do just great. Being affectionate and very caring, they make great nurses too! As writers, artists and filmmakers, Cancer is known to outshine most other signs.

Leo:

Leo loves to be the center of attraction, a clerical job involving backend paperwork would be so frustrating for him. A Leo actor might be the most satisfied person on earth! With oh-so-much-attention, what more could he ask for! These guys make excellent spokespersons or publicists.

Virgo:

Computer scientists, engineers, financial advisers and architects; you`ll find Virgos perform outstandingly in these professions. With an eye for detail, these jobs are some of the best options for this lot.

Libra:

Librans have a balanced temperament. These people know how to balance things and are very serious about making no mistakes in that. With such unbiased approach, Librans prove to be great teachers and counselors. Librans also have a thing for beauty. Stylists, beauticians and interior decorators are also some perfect options for them. The legal field attracts Librans and most Librans are doing well as lawyers and judges.

Scorpio:

Scorpions are very dedicated and hard working professionals. They are very secretive and at the same time, willing to know other people`s problems and secrets. These people will fit well as investigators. They also make great therapists and hypnotists. Don`t be startled to find a scorpion working in the science lab or as a researcher.

Sagittarius:

Sagittarians are the always-happy ones. They like solving problems and bringing a smile on others` faces. Psychiatrists, school counselors, customer service desks, managers, they`ll excel in all these career options!

Capricorn:

With a very high level of concentration, Capricorns prove to be perfect doctors and electrical engineers; they are the perfect choice for project managers too! Work which requires a lot of reading, analyzing and writing are also perfect for them.

Aquarius:

Aquarians are free birds, restricting them to a 9 to 5 schedule will suffocate them. The urge to do something different, independently, makes flexible working conditions favourable for this sign. Excellence in the field of science and technology is expected from an Aquarian person. Social work and politics are also preferable fields for them.

Pisces:

Pisceans have very strong visual imagination. A creative field such as animation is one of the best options for them, with confirmed success! Other career options include photography, filmmaking, and teaching.

4 Strategies For Remembering Everything You Learn

2014-08-15T04:56:00.003-07:00

If you're going to learn anything, you need two kinds of prior knowledge:

• knowledge about the subject at hand, like math, history, or programming

• knowledge about how learning actually works

    The bad news: Our education system kinda skips one of them, which is terrifying, given that your ability to learn is such a huge predictor of success in life, from achieving in academics to getting ahead at work. It all requires mastering skill after skill.

   "Parents and educators are pretty good at imparting the first kind of knowledge," shares psych writer Annie Murphy Paul. "We're comfortable talking about concrete information: names, dates, numbers, facts. But the guidance we offer on the act of learning itself — the 'metacognitive' aspects of learning — is more hit-or-miss, and it shows."

To wit, new education research shows that low-achieving students have "substantial deficits" in their understanding of the cognitive strategies that allow people to learn well. This, Paul says, suggests that part of the reason students perform poorly is that they don't know a lot about how learning actually works.

It's a culture-wide issue.

Henry Roediger and Mark McDaniel, psychologists at Washington University in St. Louis and coauthors of "Make It Stick: The Science Of Successful Learning," say that "how we teach and study is largely a mix of theory, lore, and intuition."

   So let's cut through that lore. Here are learning strategies that really work.
Force yourself to recall.

The least-fun part of effective learning is that it's hard. In fact, the "Make It Stick" authors contend that when learning if difficult, you're doing your best learning, in the same way that lifting a weight at the limit of your capacity makes you strongest.

It's simple, though not easy, to take advantage of this: force yourself to recall a fact. Flashcards are a great ally in this, since they force you to supply answers.

Don't fall for fluency.
When you're reading something and it feels easy, what you're experiencing is fluency.
It'll only get you in trouble.

Example: Say, for instance, you're at the airport and you're trying to remember which gate your flight to Chicago is waiting for you at. You look at the terminal monitors — it's B44. You think to yourself, oh, B44, that's easy. Then you walk away, idly check your phone, and instantly forget where you're going.

The alternative: You read the gate number. Then you turn away from the monitor and ask yourself, what's the gate? If you can recall that it's B44, you're good to go.
Connect the new thing to the old things.
"The more you can explain about the way your new learning relates to prior knowledge," the "Make It Stick" authors write, "the stronger your grasp of the new learning will be, and the more connections you create that will help you remember it later."

When you're weaving in new threads into your pre-existing web of knowledge, you're elaborating.
One killer technique is to come up with real-life examples of principles you've just uncovered. If you've just learned about slant rhyme, you could read poems that exhibit it. If you've just discovered heat transfer, you could think of the way a warm cup of cocoa disperses warmth into your hands on a cold winter's day.

Reflect, reflect, reflect.

Looking back helps. In a Harvard Business School study , employees who were onboarded to a call center had 22.8% higher performance than the control group when they spent just 15 minutes reflecting on their work at the end of the day.

"When people have the opportunity to reflect, they experience a boost in self-efficacy," HBS professor Francesca Gino tells us. "They feel more confident that they can achieve things. As a result, they put more effort into what they're doing and what they learn."
While reflecting may seem like it leads to working less, it leads to achieving more.

5 Great Open Source Project Management Platforms

2014-05-15T00:25:00.002-07:00

5 Great Open Source Project Management Platforms

Written on April 9, 2014 by samad_aidane in Tools & Techniques

Open-source has been gaining momentum for some time now. It seems that every year, more companies have been adopting open-source solutions to meet their business objectives. In fact, the results of the 2013 Future of Open Source Survey revealed that 62 percent of respondents believe that more than 50 percent of purchased software will be open source in the next five years.
Open-source software is most often-used for one of four reasons:

Low Cost
Better Security
Freedom from Vendor Contracts
Better Quality

While these four characteristics probably don’t raise any eyebrows, the reason users choose open source software might.
76 percent of respondents to an Accenture survey rated the quality of open source software as its most attractive feature. The next two most desirable characteristics? 71 percent said Reliability, while 70 percent cited Security. Price didn’t even make the top three, though it would be unwise to write off the cost savings of implementing open-source software.
Not to mention the freedom. Choosing open source software means that your business isn’t chained to a particular software vendor. If a platform is underperforming, it can be dropped.
This flexibility is particularly relevant for project management. The needs of large enterprise level projects vary widely from the requirements of small startup companies, so not getting locked in to a vendor contract is a huge plus.
Let’s examine five open source options for project management. These applications were selected for their variety of features and ease of use. It’s important to note that not all of these platforms are free, because free isn’t always synonymous with open-source.
Redmine
A popular solution in the open-source community, Redmine offers project managers a range of options for how to organize their upcoming tasks. Redmine’s controls are comprehensive and feature private and public projects, all with dedicated subprojects. Managers can also control user access through role-based controls.
Redmine features a number of project management standards, like Gantt charts and calendars as well as documents and file management, but this software really shines when used for tracking bugs and system issues. Redmine was built with the Ruby on Rails framework, and works across platforms.
EGroupWare
Especially easy to install, EGroupWare offers project managers a solution for addressing any potential interoperability issues with importing and exporting CVS files.

What is expected Income From a Website

What Is The Expected Income From a Website ...By Scott Cameron

Initial Nothing Period

One bad thing about creating a website is that there is a “Nothing” period in the money you can generate. Building a website takes time and to begin with you can’t even have visitors until you have your site built and populated with content. If done well that step may take some time and effort. Then depending on the type of website you have built it may even take quite a bit of time before you even earn your first dollar. But don’t worry the long term rewards from a website really outweigh this initial “Nothing” Period.

First Dollar

It may take some time for you to make your first dollar but once you do you have passed the hardest step of making a successful website. The first dollar is the turning point where you are no longer in the “Nothing” period and you are earning money. Yes I know 1 dollar isn’t much to talk about but all you need to do now is grow your traffic and enhance your website and that 1 dollar will turn into more.

Growth

Once you pass the 1 dollar mark your website will grow and soon earn 100 dollars then 1000 dollars and as long as you work on it, it will grow. The best thing about a website is that you can take time off and you will still be earning money. Let me explain; If you build your website up to say $1000 a week and this is based off a steady flow of traffic you could take a month off and you will still be earning $1000 a week with very little effort. In most cases if you implement your traffic building techniques right after your month off you could possibly be on even more money each week.

Potential

The potential of earning money online is not very limited, with enough work, the right knowledge and the right mind set you can potentially make millions online. There are people that work solely online and earn in excess of 10 million plus a year.

Expected Income

Even though there is a huge potential to make millions this is usually only for a very few amount of people that make it that big. We should really concern ourselves with the more expected income over time. For most people they will earn nothing while they are building and writing content for their website. Once the site is done and online, initially you still won’t make any money. With constant effort in building traffic to your website after around a few months you will likely start to have enough traffic to be making some money. To start with it won’t be too much money but after about 6 months to a year your website could potentially be making you a few thousand a month or more. With constant work and dedication within a few years your website could be making you thousands each week with little or no input from you. Maintaining the income for you website will involve very little effort in most cases (if any effort at all).

Disclaimer: This is just a rough guide to show you some expected incomes you may see. The information on this page does not guarantee that you will earn anything at all, you have to understand that everyone’s conditions are different

Top Ten Software Architecture Mistakes

2013-08-16T10:50:00.000-07:00

Top Ten Software Architecture Mistakes by Niclas Nilsson

Scoping Woes. "This is the sort of situation where a simple travel booking system ends up with full expense claim management facilities being built into it, with inevitable repercussions for project costs, timescales and quality...It is really true that no security is needed beyond simple login? Once logged into the system can users really perform any system operation?"

Not Casting Your Net Widely. "A related mistake that many of us have made is to focus on just a couple of our system stakeholders – classically the acquirer (who is paying for the system) and the end users get all of the attention."

Just Focusing on Functions. "…unless the system exhibits a whole range of qualities (such as performance, security, maintainability and so on) it is unlikely to be successful."

Box and Line Descriptions. "There are two reasons why the [single, all inclusive] huge Visio picture doesn’t work well as an architectural description: firstly, it’s trying to show too much information in a single representation, and secondly, no one is really sure quite what each of the different types of symbol that you’ve drawn mean."

Forgetting That It Needs to be Built. "Common things to watch out for related to building the system include designs that the developers or testers don’t really understand, technologies that they aren’t enthusiastic about or don’t have the time to learn, and new technologies that don’t yet have good tool support or perhaps impose a new and unfamiliar way of working."

Lack of Platform Precision."…its no longer sufficient to simply say that you “need Unix and Oracle” when specifying your platform. You need to be really precise about the specific versions and configurations of each part in order to ensure that you get what you need. This will allow you to avoid the situation where you can’t deploy your system because someone has helpfully upgraded a library for one part of the platform without realising that it means that something else will no longer work."

Making Performance and Scalability Assumptions. "Start considering performance and scalability early, create performance models to try to predict key performance metrics and spot bottlenecks and get stuck into some practical proof-of-concept work as your design ideas are forming. This will all help to increase confidence that there aren’t any performance and scalability demons lurking in your design."

DIY Security. "A mistake made in many systems over the years has been to try to add security into the system using “home brew” security technology. Be it custom encryption algorithms, a developer’s own auditing system or an entire DIY access control system, locally developed security solutions are rarely a good idea. While most of us think we could probably whip up a clever piece of security technology in no time, we’re usually wrong."

No Disaster Recovery. "The key to getting resources to implement a DR mechanism for your system is to be specific and quantify the cost of system unavailability in a number of realistic scenarios. If you can also estimate the probability of the scenarios occurring then you can use these two figures to convince people that DR is important and to justify a certain level of budget to implement it."

No Backout Plan. "Make sure that whatever happens during the deployment of your system or upgrade that you have a documented, reviewed and agreed backout plan to allow you to restore the environment to its state before you started deployment."

Kyu Darein, ki Zindagi Mein Kya Hoga,

Kuchh Nahi Tau Kya, Tajurba Naya Hoga.

Tawakkul hai jo Khuda pe, na kar fikar kab kya hoga....
Bas bharosa rakh uss rab par ki .....
Wahi hoga jo manzoor-e-Khuda hoga.....

When Kshitij Nadekar finalised the house he wished to rent in Pune a year ago, he thought he would keep there for 2-3 years until he bought his own house. "The place was in an exceedingly} fairly condition and was very near my workplace. So, I forthwith signed the agreement with the owner," says the 37-year-old management govt. Nadekar had united to pay a monthly rent of Rs 5,000 and furnished with Rs 50,000 as deposit cash. However, six months later, the owner wished to extend the rent by Rs five hundred because the rentals within the space had gone up.

"I had 2 choices—pay the additional cash or rummage around for another house. My landholder told Pine Tree State that such a rise was the norm, and since nothing was mentioned within the lease agreement, I had very little choice however to pay the extra cash," he adds. Nadekar might have avoided this problem if he had scrutinized the rent agreement fastidiously and created changes that might have served his interests higher. However, most tenants don't seem to be even responsive to the points that ought to be enclosed within the rent agreement. Here are the items you ought to check whereas separation through the contract.

Is the lease giver the particular owner? Before you sign the agreement, make sure that the person you're transacting with is that the actual owner of the property.

If you fail to examine the agreement and sign it, you'll be control responsible for invasive. "Of course, if such a clause isn't mentioned, the tenant will hold the opposite party chargeable for cheating and committing fraud," adds Ahuja.

What will the rent agreement contain? A rent agreement includes the terms and conditions underneath that the property is given on rent. It specifies the rent worth and therefore the tenure that the agreement is formed, furthermore because the security quantity that has to be deposited with the owner by the tenant.

The agreement ought to conjointly clearly mention the day before that the rent is predicted to be paid. as an example, it may well be the fifth or tenth of each month.

If either party fails to honour the terms and conditions of the agreement, it'll become void and therefore the aggrieved party may claim penal charges. The tenure of a rent agreement is typically eleven months, unless otherwise per the contract. If it's for quite a year, it's obligatory for the owner to urge the document registered. The agreement ought to conjointly specify the notice amount and penalty for cancelling the agreement while not finishing the required amount. Typically, a two-month notice is served just in case of high rental properties, whereas one month's notice is decent for low rental ones. What do you have to check? A tenant ought to verify whether or not the owner has enclosed a rent increase clause within the lease agreement, that might be wont to increase the rent once a few of months.

"The best thanks to safeguard yourself is to confirm that the agreement specifies the dates on that the rent increase are applicable and therefore the proportion of increase," says Ahuja. you ought to conjointly certify that there's a clause on the sale of the house. If the owner decides to sell the house throughout the term of the rent agreement, you ought to skills several months you may get to look for an additional appropriate accommodation. it is also vital to see that each one the appliances and therefore the connections within the house square measure operating properly before you sign the agreement.

Usually, minor repair work for put in electrical appliances is that the responsibility of the tenant and he has got to purchase them. However, if the property is broken owing to negligence on your half, the owner will truly use the protection cash deposited with him for ending the required renovation. you furthermore mght have the correct to examine the documents that prove all previous bills associated with the house are paid, particularly the electricity, water and gas bills. whereas you're at it, certify to see the papers that state the land tax has been paid by the owner.
