This is why SSD is better than HDD

As we know that the technology is becoming in the fist of people day by day. And devices are becoming smaller yet performances are getting faster and faster. Well, today we are going to talk about that kind of evolution.

Comparing HDD vs SSD.
SSD = stands for Solid State Drive and HDD stands for Hard Disk Drive.

They are both storage devices where computer saves all its data. How fast the computer will load and how fast a file will open up, it all depends on the speed of the storage device.

Let's talk about HDD first:
IBM invented HDD in 1956. There are some discs (yes if you break one you will find few discs which staked on top of another) inside the HDD and computer reads or write on the discs by using magnetism. The speed of HDD depends on how fast the disc spins, if it spins faster the speed will be fast as well.

Let's talk about SSD now:
Usually what ever mechanism is used in pen-drives and memory-cards the same mechanism is used in SSD as well. It saves the data by using some complex circuits. So now let's compare between these tow.

HDDSSD
1. More Physical Damage1. Less Physical Damage
2. Nosy, Vibration and heat2. No Nosy, Vibration or Heat
3. Consumes More Power3. Consumes Less Power
4. Boot up 30-40 Sec4. Boot up 10-13 Sec
5. Writes = 50-120MBps5. Writes = 200-500MBps
6. Opens a file 30% Slower6. Opens a file 30%Faster

Well, I hope you have learned something about your computer drives today and now you know why SSD is better than HDD. To be honest, the noise of my laptop's hard drive (although it's way quieter than a desktop) some times pisses me off, so now I'm thinking of shifting to SSD.

How can you search any website contents without visiting that site?


Did you know that you can search contents of any websites without even visiting that specific site?
Well, let's talk about that in this post. You might be thinking why can't you use a search engine of that site? Of course you can, but what if that site doesn't have any search engine at all? Or maybe it has one but in desktop version only, and when you visit that site using a mobile then you can't find any search box like this site.
Ad

To overcome that problem there is a simple solution and that is search it by using Google. Yes, you can search deep contents (not only titles) of a site with Google as well. As you probably have already seen in the picture above and worked out, but let me explain it if you didn't understand it fully.

There are tree sections here:
1. Your search query.
2. The tag which tells the Google where to search.
3. The specific site.

For example:  facebook site:amazingtips247.co.uk Now as you can see green highlighted word is what I searched. The yellow highlighted word (site:) word and the website right after it (amazingtips247.co.uk) told Google that I wanted the results from that specific website and not from other websites.

Note: It's better to put www. before any website otherwise google may show you results of the popular website with that name first and might show results from other similar site too. And one more thing is that you can only a result if Google has indexed that site/page.

I hope you've learned something useful today. :)

I got shocked by Facebook's tracking!

Well, I really got shocked when Facebook showed me the ad below!
OK, let me tell you why I got shocked. Yesterday I bought a switch from eBay by using my tablet, and to connect the internet I used my phone as a hotspot and my browser was Chrome.


And when I was on Facebook I was using, Laptop, Firefox as browser and Wi-Fi for internet connection. As you can see that there is no connection between these devices and browsers. Ok if you still didn't get it let me break it down out for you.
Ad

When I bought the switch:

Device: Tablet
Browser: Google Chrome
Internet connection: My mobile phone as a hotspot.


When the Facebook ad showed up:

Device: Laptop
Browser: Mozilla Firefox
Internet connection: Wi-Fi

Well, now you can see that there is no connection between these two situation, but how come Facebook still managed to show me the ad so accurately?

That was not coincidence, because I never searched that switch with that browser as far as I can remember. But how did it show that specific ad on the day that I bought it? Does it mean that big companies exchange cookies (browsing histories and stuff) with each other?

In this case:
  • Google Chrome
  • Mozilla Firefox
  • eBay
  • Facebook
  • Mobile network
  • Wi-Fi modem provider

Are they all connected?

Remember when you visit a site (You might find 99.99% or maybe 100% sites are like this nowadays) it stores a cookie on your computer about your browsing behaviour. It does that by the help of a script and the browser. So when you go to that particular site again, they can find out what was your browsing behaviour last time. Now if one website can read another  website's cookies then that means that website's cookie is not secure enough or they probably sharing the info with each other.

In the above case everything was different the device, browser and the Internet connection but they still able to predict accurately that means there must be something that connect them. We are living in a time when we're being tracked so remotely yet so accurately that it boggles our mind. We don't want to be tracked but we can't stop surfing the web either.

Anyway, if you find this helpful then feel free to share this with your friends who still think that they are not being tracked.

Shortcut way of Copy & Paste


If you use computer frequently then you probably come across copying and pasting a lot. People usually go for the normal way of copy and paste or if someone want to do that a bit faster then they use keyboard shortcuts. But in this post you will find out how easily you can copy and paste faster and you won't have to go through all those hassles.

Ad

This called right click dragging.

Just right click and hold which ever file or  folder you want to copy and then drag it to the destination folder and then release it. You will see a context menu with some options.

Copy here: It will copy the original file.
Move here: It will bring the original file to the destination folder.
Create shortcuts here: It will just create a shortcut of the original file.
Cancel: It won't do anything.

Shortcut way of text selecting.
  1. One click and drag: selects charter to charter.
  2. If you click twice and hold on the second click then drag it will select word by word.
  3. If you click 3 times and hold on the third click and then drag, it will copy paragraph to paragraph.

Celebrities Speak Out On Fame and Materialism


What ever they are saying kind of makes sense because once someone gets almost everything what they want in life, then they don't have any new things left to enjoy, and what ever they see they think oh I've already got that one or I can get that at any time. Once they get bored in everything they try to calm down and look for love and think how can they mix with normal people (because rich people hate each other), but they can't because normal people think rich people are way too high above them so they don't want to mix with them. And that's when these rich people feel lonely and start saying oh money doesn't buy you love. Well, money certainly buy many things which could be source of love.

Why rich people feel lonely?
As I've said rich people always compare wealth of each other and think how can they get more money than each other and because of that they start hating each other. And when they don't find love in rich people they try to come back to the poor people, but poor people stay away from them because they think you can't trust the rich people or rich people are way to high above them so it's better to stay away from them.  Now you get the result loneliness.

If they don't like money, why don't they give it away and start living as normal people? There are plenty of poor people in the world. They will keep saying these words but they can leave their lavish lifestyle.

Go to the people who are in need of money and say "Money doesn't buy you love" they will certainly show you what money can do and what it can't. You probably for forgot where and how to spend your money.

Some comments:
* [They should give away their money then. stop whining about everything lol]

* [Fame, materialism and all the rest of it only enhances the life you currently have. you can be perfectly happy without it, but if you choose to pursue it, i think that's perfectly fine too as long as you don't let it override your life]

Sorry! I had to show other side of the story because these ultra rich people became so rich that now they think that money is almost useless, but I'm with the poor people because I know very well how it feels if you don't have much money or you don't have it all.

Toilet tissue Alert with ultrasonic sensor

Well, it might sound odd that you need an alert to know when your toilet tissue is running out. This is just an idea and maybe helpful as well if someone can make it even precise and reliable. And it could be a luxury item for rich people, but anyway I made this as an example. Let's first see what you need to make it.
Ad

  • 1x RGB led.
  • 1x Ultrasonic Sensor.
  • 1x Arduino Board.
  • Few jumper cables.
  • And the sketch below.

The Sketch
int redPin = 4;
int greenPin = 5;
int bluePin = 6;

int trigPin2 = 8;
int echoPin2 = 9;

#define COMMON_ANODE
void setup() {
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
  Serial.begin (9600);

  pinMode(trigPin2, OUTPUT);
  pinMode(echoPin2, INPUT);
}

void setColor(int red, int green, int blue)
{
#ifdef COMMON_ANODE
red = 255 - red;
green = 255 - green;
blue = 255 - blue;
#endif
analogWrite(redPin, red);
analogWrite(greenPin, green);
analogWrite(bluePin, blue);
}


void loop() {
Serial.println("\n");

    int duration2, distance2;
    digitalWrite (trigPin2, HIGH);
    delayMicroseconds (10);
    digitalWrite (trigPin2, LOW);
    duration2 = pulseIn (echoPin2, HIGH);
    distance2 = (duration2/2) / 29.1;

      Serial.print("2nd Sensor: ");
      Serial.print(distance2);
      Serial.print("cm  ");
 
    if (distance2 >=9) {  // Change the number for long or short distances.
 setColor(255, 0, 0);
 delay(1000);
  setColor(0, 0, 0);
    }
   else if (distance2 >=7 && distance2 <=9) {  // Change the number for long or short distances.
 setColor(255, 208, 0);
 delay(1000);
  setColor(0, 0, 0);
    }
      else if (distance2 <=7) {  // Change the number for long or short distances.
 setColor(101, 255, 0);
 delay(1000);
  setColor(0, 0, 0);
    }
 else {

    }
 
delay(3000); // 3 seconds delay
}

Now let me explain what it does. Because it works by calculating the distance between the sensor and the tissue roll, so you might have change it according to your need. In this case it turns on the red led when the distance exceeds 9cm. And if the distance is 7cm to 9cm it turns on the amber led, and the if it's less than  7cm it turns on the green led. After take a rest for 3 seconds and then starts the sensor again to see how much tissue has been used. You can make it take the measurement after each 5 or 10 minutes if you want by changing the number to what ever amount you want.

How to see someone else's analytics data of URL shortened by Google

Have you ever come across this (goo.gl/lILGlq) kind of URL  where you can't see what you clicking on?
Well, that is a short url for a long one and it can even track how many people have clicked on that link when and where are they from. This kind of url people use to see activity on that particular link and sometimes spammers and hackers use it to send visitor to a fishing site where they try to steal information from you.
Ad

The url which you've seen at the top is from Google URL Shortner. And if you see anywhere goo.gl/... then that means it's from Google URL Shortner. So if you think something wrong with the link and you want to investigate more about the link then you can follow the steps below.

  1. Go to this site https://goo.gl/#analytics/goo.gl/ (don't worry I'm not sending you to a dodgy site it's Google's own site)
  2. Now after the last / slash put the shortened URL in the case lILGlq and then put /day  
  3. Then hit the enter key. Full URL should look like this https://goo.gl/#analytics/goo.gl/lILGlq/day
That's it, now you know how to see  the stats of an unknown url shortened by Google. Enjoy!!

Arduino For Loops Explained

Well, this the best ever explanation about "For Loop" I have ever found. In this post I will see 3 kind of sketch and how they work. So let's start with the first one.
Ad

Sketch 1
int led = 4;

void setup() {
pinMode (led,OUTPUT);
}

void loop() {

digitalWrite (led, HIGH);
delay(500);

digitalWrite (led, LOW);
delay(500);

digitalWrite (led, HIGH);
delay(500);

digitalWrite (led, LOW);
delay(500);

digitalWrite (led, HIGH);
delay(500);

digitalWrite (led, LOW);
delay(500);

digitalWrite (led, HIGH);
delay(500);

digitalWrite (led, LOW);
delay(500);

digitalWrite (led, HIGH);
delay(500);

digitalWrite (led, LOW);
delay(500);

delay(3000);
}

The above sketch seems too long and you might think it probably does a very complicated task. Well, it although it seems like that but it only turns a led on and off 5 times then wait for 3 seconds and it starts the task all over again. You can do the same task with less code by using a "for" statement.

Sketch 2
int led = 4;
int i;

void setup() {
pinMode (led,OUTPUT);
}

void loop() {

for (i=0; i<5; i++){
  digitalWrite (led, HIGH);
delay(500);
  digitalWrite (led, LOW);
delay(500);
}
delay(3000);
}

Now you can see that sketch 2 looks very nice and tidy and does exact same task as sketch 1, this is the miracle of the for statement. Let me explain about it a bit.

for (i=0; i<5; i++){
digitalWrite (led, HIGH);
delay(500);
digitalWrite (led, LOW);
delay(500);
} 

Three thing are going on in the brackets after the for ().

i=0; "i" is a reference point of something that you want it to start from. For example: If you write i=3 that means you want the code between the two yellow curly brackets to run from number three. So if your code is (i=3; i<10; i++) so it will run 7 times only and not 10 times.
i<5; It means that if "i" (which is equal to 0 in the sketch) is less than 5 then run the code (what ever code you put in between the yellow brackets) until it reaches equal to 5.
i++  Well, this bit of code adds value of 1 each time the code between yellow brackets has been run. For example: if the code has been run once it will add one and if it has run for 4 times it will add 4+1=5 so after adding the last 1 it will stop because the "i" is equal to 5 now and 5 is not less than 5 so the "For Statement" will stop there and ignore what ever code is between the yellow brackets.
Ad

Note:
Remember after reaching the maximum number it will only ignore that particular for statement and it will continue to run other codes.


One last sketch I want to finish this post with.
Sketch 3
int led = 4;
int i;

void setup() {

pinMode (led,OUTPUT);

for (i=0; i<10; i++){
  digitalWrite (led, HIGH);
delay(500);
  digitalWrite (led, LOW);
delay(500);
 }
}

void loop() {
 
}

The sketch 3 is very helpful when you trying to run a code for certain amount of times then turn it off until you click the reset button and turn it on again.

That's all for this post I hope you've fund it helpful. :)

Google is planning to add an ad blocker to Chrome

Are you one of those who hates seeing too many annoying ads everywhere when you visit a site? There are many websites where you will find ads after every few lines or there might me not any content at all besides ads. Yes that is very frustrating! and sometimes you clicking next after next still you can't find the main thing that you wanted.
Ad

Well, very soon those annoying ads can be blocked by Google's own web browser Chrome as wsj says. This feature will be available in both Desktop and Mobile version. Although many people (visitors) maybe very happy to see this feature but many publisher may not be happy at all, specially those who are heavily dependent on their ad revenue.

If you read the article properly you'll see that Google might trying to filter certain kind of ads from appearing on the site. We can think of few things here.

1. Will Google block their own (Adwords) ads?
If that's true then Google will lose huge amount of money. By the way who want's to be hurt by himself? If you didn't understand then let me explain you. Adwords is a Google's own program, through which advertisers show their ads on different sites (this site is one of them). So imagine someone comes to this site by using Chrome and Google blocks the ads. So in that case Google will lose money, even though it might be small amount (because this site small) but imagine you add 100,000 of sites like this.

2. Google maybe wanting to block other ads.
Well, recently I've seen many ads network similar to Google on different websites and it's probably Google doesn't pay much to their publishers, they are too busy pleasing advertisers maybe that's why publishers are looking for alternative way to Google. So when Google saw that publishers are going away so they came up with this idea that just block the other network ads and just show Googles ads.

If they think like this then it's very bad idea, because eventually publishers will find out and might leave Google altogether. That's because publishers get less money from Google ads and that's why they try to make a bit extra from other networks. So if Google blocks other income source then of course they will go away. Instead of  taking care about the publishers and think about how they can keep them happy with Google they came up with this idea.
Ad

3. Blocking ads becoming a good source of income.
You probably don't know that the ad-blockers doesn't always block all the ads. The developers of ad-blockers let some ads to show on the site even though you've listed the site in your block ads list. That's because those ad network has paid the ad-blocker developers not block their ads. So Google maybe thinking of getting that market too. It's all about money. :(

4. Visitors should know this.
Well, this not true that all the sites are ad infested. You might find many click-bait site which full of ads and you think all the other sites will be the same. No, not at all. You will find many decent sites which doesn't use too many ads to annoy readers. They know that they need readers and you know that you need the good contents. So if you block ads from all sites then those good site might lose interest and stop producing good contents or maybe block you from accessing. And that won't be good, because how many sites are you going to pay for their contents?

Here is one thing I just want to finish with that Google Chrome is pretty famous web browser, it can effect many people. Here is one snapshot of browsers people have been using to see this site. Total number of hits 17,486 all the browsers combine, and 9,273 hits just from the Google Chrome.

Well, I think visitors should understand that they shouldn't block the ads at least from those sites that they are getting benefit from. Otherwise it's kind of selfishness that you want the good things from them but you don't want to sacrifice anything.

Control speed of a small DC motor with push button

Long time ago I made video about PWM where I used an Arduino to control the power. In that video I used 3 sketches, one for slow speed, one for medium and one for fast speed. I had to upload different sketch to make the motor spin in different speed.
Ad

Although I tried my best to find out how I can use one sketch and set different speed, but could not find it at that time. And here I've found it and it works fine, but the problem is you have to reset before you send another command. I think it's still way better than the other one which I made earlier.

Why do you have to click the reset button every time?
Well, that because (if you use the sketch below) then when you send a command to the Arduino board to spin the motor in one speed, it goes into loop by turning the motor on and off for certain amount of time. And it works so fast that it doesn't even have time to get another command, so it's ignores it as if nothing really happened. That's why you have to click the reset button to bring it back from the loop.

The sketch
const int motor =  5;      // the number of the motor pin

const int button1Pin = 2;     // the number of the pushbutton pin
int buttonState1 = 0;         // variable for reading the pushbutton status

const int button2Pin = 3;     //
int buttonState2 = 0;         //

const int button3Pin = 4;     //
int buttonState3 = 0;         //

void setup() {
  // initialize the motor pin as an output:
  pinMode(motor, OUTPUT);
  // initialize the pushbutton pins as an input:
  pinMode(button1Pin, INPUT);
  pinMode(button2Pin, INPUT);
  pinMode(button3Pin, INPUT);
}

void slow(){
  digitalWrite(motor, HIGH);
  delay(15); // Change the numbers if you need to.
  digitalWrite(motor, LOW);
  delay(40); // Change the numbers if you need to.
  slow();
}

void medium(){
  digitalWrite(motor, HIGH);
  delay(15); // Change the numbers if you need to.
  digitalWrite(motor, LOW);
  delay(20); // Change the numbers if you need to.
  medium();
}

void fast(){
  digitalWrite(motor, HIGH);
  delay(30); // Change the numbers if you need to.
  digitalWrite(motor, LOW);
  delay(10); // Change the numbers if you need to.
  fast();
}


void loop() {
  // read the state of the pushbutton value:
  buttonState1 = digitalRead(button1Pin);
  buttonState2 = digitalRead(button2Pin);
  buttonState3 = digitalRead(button3Pin);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState1 == HIGH) {
    // turn Motor on:
    slow();
  } else {
    // Nothing
  }

   if (buttonState2 == HIGH) {
    // turn Motor on:
    medium();
  } else {
    // Nothing
  }

  if (buttonState3 == HIGH) {
    // turn Motor on:
    fast();
  } else {
    // Nothing
  }
}

The sketch is in action below
I hope it helped you.

Do you turn your PC off every day or keep it on

Are you going to keep your computer on or turn it off when you finish your work? If you have that question in your mind then you will find the answer here. There are some benefits of both of keeping it on and turning it off. So it all depends on you. Some people think that it will cause harm to the PC if you turn it off and that's completely false thinking. If you shut it down correctly then it will not cause any harm to your PC in fact it's beneficial.
Ad

Can you just pull the plug off?
Well, you never ever do that, if you do then that might cause big problem. To turn it off there is way of shutting down, use it to turn it off safely.


Advantages of turning it off every day
  1. Less usage of electricity: Usually desktop/PC consumes quite a bit of electricity, so by turning it off you will be saving some electricity that means you have pay less electric bill.
  2. Solving Temporary problems of the system: By working continually the system might developed some temporary problems. So if turn it off and then turn it back on again it can solve those problems. Well, this case I think "Restart" option is better.
  3. Protection from slowness: If you use it for long time it might get slower, but if you give it a break by turning it off it will regain the normal speed again.
  4. Relief from the fan and notification sound: Well, I haven't use noisy PC for long time but in the shop (where I work) the till makes so much noise and I hate that, some times I feel like breaking it down. But then again think that if I do so I'll lose my job. So by turning it off it won't drive you crazy.
  5. Durability: Well, of course if you use less of something it makes the thing last longer.

Ad
Disadvantages of turning it off
  1. Start up time: You might feel uncomfortable to turn it on and off all the time, and it might even take some time each time you turn it on. Plus if you turn it off without saving the file (which you were working on) you might lose it for ever, unless you have got back up for that file.
  2. Electricity usage: It is true that when you keep your PC on it keeps consuming the electricity, but if you are doing some projects and sometimes you just want to turn it off for few minutes then it's better to put in "Sleep" or "Hibernation" mode. If you do that it won't effect your work and it will consume minimum amount of power.
Summary:
If you think that you're not going to use it for long time then it's better to shut it down. But if you think you will use it in few minutes then it's better to keep it in "Sleep" mode.

How to read fb message on uc browser without messenger


I've noticed that many people wanted to know how they can see Facebook messages in UC Browser without getting redirected to Facebook Messenger app. Facebook really made life hard for many people. I don't really get it, why do they have to redirect everyone to their app? They should have left the web option, because not everyone like all the heavy apps to clog their phones. Anyway, after so many request as you can see below.

  • how can i see fb messege with out seen it in uc browser 
  • how to open fb msg without using messanger on uc browser
  • how to read fb message on uc browser without messanger
  • messages in fb without messenger in uc browser
  • uc browser to see messages
I thought let me just download the UC Browser and and find out if there is any option of seeing fb messages so that people don't have to download the messenger. And after playing around with it sometime here is what I've found.
  1. Click on settings.
  2. Browsing Settings
  3. Website Preferences
  4. Others
  5. Desktop
Well, that's how you turn mobile sites into desktop sites in UC Browser. And because you can still see your messages in desktop mode so that's why you will be able see with uc browser too. But I'm little bit disappointed because although you can see messages in uc browser, but it's very limited and basic version of Facebook message. It's still better than nothing I guess, because many people have visited my other post which got completely different setting than this one. I'm kind of feeling sorry for those people who saw the post and thought (well, this setting is not the right one for us).

Anyway I hope this helps you, if it did feel free to share with your friends. :)

How Google has changed showing ads over the years

If you are a AdSense publisher then you probably already know that there are so many policies about how you should place an ad code on your site. And one of them is "Publishers should avoid website layouts in which the ads push content below the fold. These layouts make it hard for users to distinguish between the content and ads."
Ad


Well, I'm really curious to know that Google tells us how we should place the (farther away from the content) so that people don't click it without knowing that it's not the part of the content. And at the same time they are going from full visibility to stealth. Why is that?  I think they have found out that if the ads are  visible too much people don't click on it, so they earning less money. And that's why they are going so stealth that it's almost hard to notice the "ad" sign.

On one website I read that it is good because now advertisers can get more visits. Well, then my question would be what if other publisher do the same (go almost invisible like Google)? That will serve the same purpose I guess. OK I understand that if someone just click on an ad and don't really like destination (advertiser's) page, he might lose money. That's why advertisers don't like this kind of clicks. That's right, but Google don't charge them if someone clicks on an ad and then don't stay on the destination page for some time anyway. So the question still remains, If Google can go stealth then why not other publishers?

Once upon a time advertisers would like to die just to get a little space on some website and now they getting free hits (those hits that people don't stay on their sites for about 30 seconds or so) and publishers have to provide free space for them. What a time to living in! :(

Why can't I turn on my mobile hotspot (Androind)? Solved

If you use your mobile as a hotspot a lot like me then you probably have come across this problem. And the problem is that after turning the hotspot off it still stays half green and you can't turn it back on again. It simply doesn't respond. So how can you solve this problem then?
Ad

Well, here is the solutions:
Solution 1: Just restart you phone and it will be normal again.
Solution 2: For this one you don't need to restart you phone.
  1. Click on the gear icon just above the hotspot icon, as you can see in the picture above.
  2. Then choose "Tethering and Mobile hotspot".
  3. Over here you might see the hotspot is off, just click on it.
  4. Now you will see a slide bar just next to "Mobile hotspot", just click on it to turn it on then might turn it off if you want to.
That's it the problem is solved. I hope it helped you. Thanks for reading, feel free to come back for more tips like this. :)

Samsung Galaxy S8 Plus BEND Test

Most of us probably see it in the dream but in real life we can't afford to buy one. And some people have way lot of money to waste, here is one guy who tried to compare "Samsung Galaxy S8 Plus BEND Test vs iPhone 7 Plus!" to see how they cope with bend resistance.

Ad

First he bragged about iPhone 7 Plus's cover, it's supper tough and all that but at the end found out that Galaxy S8 Plus is more tougher than iPhone 7 Plus. He thinks the bend point of iPhone is where the sim card tray is. Although that is quite week point but I think he put more pressure on that point that's why it bended. Otherwise you can clearly see where ever he put a bit of pressure he just ripped it off, as you can see near the camera.


Conclusion:
As per this experiment we can say that Samsung Galaxy S8 Plus is more stronger than iPhone 7 Plus.

Realtek RTL8192EU doesn't support windows 8 (solved)


Recently I bought a WiFi adopter called "Realtek RTL8192EU Wireless LAN 802.11n USB 2.0 Network Adapter" and when  tried to install it on my laptop I got a problem. But after solving it I thought why not share with other people some one can get benefit from it.
Ad

So here is what happened. After putting the CD in and running the auto run I came across few options. Windows, Mac OSX, Linux, User Manual and Brows CD. So I clicked "Windows" because my laptop runs on windows. After that a window popped up asking for permission to install the drivers. I got scared and thought never know they might install virus on my PC, so I closed it and thought let me do it in another way. And that was plugging the adopter first and let PC find the driver or guide it to the actual folder where the driver is.

So I plugged in the adopter let PC to look for the driver, when it didn't find I clicked "Windows" to install it normally but this time it started saying that "Sorry! We do not support this operating system!!". I thought forget it and let me find the driver folder in the CD.  So I opened the driver folder by following this path "Browse CD >> Windows >> RTWLANU_Driver >> WinX64" and copied the WinX64 folder and pasted on my desktop. After that I plugged the adapter again, and this time it automatically installed the driver and I could see WiFi2 has been created.

Note:
In the final driver folder RTWLANU_Driver you will find some more driver folders for other windows and operating system, please choose which ever right for your system.
That's all, I hope it helps you. :)

Train your pets with custom commands


This is why I love Arduino so much, it opens so many ways of innovations. Recently I saw a video where someone was giving her/his cats food when they were ringing the bell. So after watching that video I thought why not make multiple button with different commands so that it can express the exact thing that it wants.
Ad

For example: You make  one button for food, one for water and one for go to toilet. Or maybe make 5/10 different buttons for different food, so if the cat doesn't like one kind of food it will ask for different one and that's how you might even find out his best food.

Some people might say well you can make a cat feeder so what's the point making buttons?
That's right and even I can make the cat feeder as well if I want to, but this is for those people who enjoy feeding their pets and by doing this you are giving the cats/dogs more choice of foods and stuff.

What do you need to make it work?
* 1× Arduino board.
* 1× Catalex Serial mp3 player with micro sd card.
* 3× Push button switches.
* 3× 10k ohm resistors.
* Some jumper wires.
* And finally the sketch, which you can find right below.

Note:
Remember you need to have three soundtracks in your SD card and rename it by 001, 002 and 003. if you don't know how to run a mp3 player with Arduino then please read this post first I have explained it in details.

The sketch
#include <SoftwareSerial.h>
#define ARDUINO_RX 5//should connect to TX of the Serial MP3 Player module
#define ARDUINO_TX 6//connect to RX of the module
SoftwareSerial mySerial(ARDUINO_RX, ARDUINO_TX);
static int8_t Send_buf[8] = {0} ;

#define CMD_SEL_DEV 0X09
#define DEV_TF 0X02
#define CMD_PLAY_W_VOL 0X22

const int buttonPin1 = 8;
int buttonState1 = 0;

const int buttonPin2 = 9;     // the number of the pushbutton pin
int buttonState2 = 0;         // variable for reading the pushbutton status

const int buttonPin3 = 10;
int buttonState3 = 0;

void setup()
{
    mySerial.begin(9600);
          Serial.begin(9600);
      delay(500);//Wait chip initialization is complete
      sendCommand(CMD_SEL_DEV, DEV_TF);//select the TF card 
      delay(200);//wait for 200ms

     pinMode(buttonPin1, INPUT);
     pinMode(buttonPin2, INPUT);
     pinMode(buttonPin3, INPUT);
}

void loop() {
  buttonState1 = digitalRead(buttonPin1);
  buttonState2 = digitalRead(buttonPin2);
  buttonState3 = digitalRead(buttonPin3); 

  if (buttonState1 == HIGH) {
sendCommand(CMD_PLAY_W_VOL, 0X1E01);//This doorbell is for friends and family.
  }
 
else if (buttonState2 == HIGH) {
sendCommand(CMD_PLAY_W_VOL, 0X1E02);//This doorbell is for post men.
  }

else if (buttonState3 == HIGH) {
sendCommand(CMD_PLAY_W_VOL, 0X1E03);//This doorbell for is normal people.
  } 
}

void sendCommand(int8_t command, int16_t dat)
{
  delay(20);
  Send_buf[0] = 0x7e; //starting byte
  Send_buf[1] = 0xff; //version
  Send_buf[2] = 0x06; //the number of bytes of the command without starting byte and ending byte
  Send_buf[3] = command; //
  Send_buf[4] = 0x00;//0x00 = no feedback, 0x01 = feedback
  Send_buf[5] = (int8_t)(dat >> 8);//datah
  Send_buf[6] = (int8_t)(dat); //datal
  Send_buf[7] = 0xef; //ending byte
  for(uint8_t i=0; i<8; i++)//
  {
    mySerial.write(Send_buf[i]) ;
  }
}

One quick note: Try not to connect the RX and TX wires before uploading the sketch, it might not work if you do so.
That's all for this post, hopefully it helps you. :)

Where can I find saved/recorded file of Voice Aloud Reader

Well, if you don't know what Voice Aloud Reader is then please read this post. In this post I just want to talk about where the sound files go when you convert the texts into audio?
Ad

You might get confused when you see the path "Recorded file: /storage/emulated/0/Android/data/com.hyperionics.avar/files/Name of your file". Actually it's very simple. Just open your "My Files" >> then open "Device storage" >> from here it's normal as you saw in the picture. "Android folder" >> then "Data" >> "com.hyperionics.avar" >> "files" >> here you will find all of you saved/recorded files.

OK, you might think it's very simple. I know it's very simple for those who already know but some people still can get confused by this "/storage/emulated/0/" path, so I thought it would be better if I share it. Anyway this app is very useful for those who don't want to read long articles, you can just make this app read for you.

Best text to speech app android (almost in any language)

Nowadays we can see many text to speech apps on play store, some of them are free and some you might need to pay for. But you never know which one is good and will work for you. So here is one I've found very useful that's why thought why not share this with every one.
Ad

If you are a regular reader of this blog then you probably already know that I wrote about another text to speech app, which is quite good and helpful, and in some cases I prefer that one.

How does it work?
  1. This app is very simple, just install it and go to what ever site you want to hear the audio of (in any language). 
  2. And share the link with "Read in Talk". If you don't know how to share a link then click here.
  3. After that it will first copy all the texts and show you in the app. Now you will have to manually choose what language the text is and select from the drop down menu.
  4. Once you've done that, now click on the play. That's all.
 If you find difficult to understand then you watch this video.
Note:
I have tried few language and couldn't make it read Arabic texts, so I'm not sure if it can read Arabic or not.
This app can be very beneficial for those people doesn't want to read long article. You can just listen to it and won't have to read A to Z.

A kid wants to be a Smartphone and she's got quite solid reason for that

A video has been made on the basis of how parents behave with their kids nowadays. Most of the time they are too busy with their work, playing games and chatting on the phone or on social networking sites. It seems like they love more of the virtual world than real world. Here is one example of that, although the video might be imaginary but the concept is pretty real.
Ad

Teacher: What do you want to be?
Student:  A Smartphone.

Teacher: Why would you like to be a Smartphone?
Student: My parents love smartphone very much.

  1. Whenever my father goes somewhere he always takes smartphone with him. But he never takes me.
  2.  My mother receives the phone call as fast as she can, when it rings. But she does not come to me even if I cry.
  3. My father plays game on his smartphone. But he doesn't play with me.
  4. I ask my father to cradle hold me, but he does not do that. But he always cradle hold  the smart phone. (She means the smart phone is always in her father's hand.)
  5. If I ask my mom to play with me, she yells at me saying don't you see I'm chatting on the phone?
  6. My father sleeps while keeping the smartphone beside his head. But he never sleeps cuddling me.
  7. My mom never forgets to charge her smartphone. But sometimes she forgets to give me food.
 I want to be a smartphone so that I can always stay beside my mom and dad.


Try to spend some time with your kids, they will remember that for ever otherwise you might end up in old people's home when you get old and no one will ask about you.
