Fix Scanner Failure Message on HP Officejet 4500 printer

After buying $50 worth of ink, my HP Officejet 4500 printer threw up a "Scanner Failure" error, rendering it useless. I took it out back to "fix it", but then decided to fix it. Basically, I had to remove the cover, the glass and then lift up the scanner bar and plop it back down on the track. Here are the visuals of that process.

Android FusedLocationProviderClient

In hopes of obtaining GPS location faster, I implemented the FusedLocationProviderClient and removed the old LocationManager.GPS_PROVIDER. Below is a snippet of the new simpler approach that I used in the latest update of Widespread Augmented Reality.

setContentView(R.layout.main);

wargps = (EditText) findViewById(R.id.wargps);

locbtn = (Button) findViewById(R.id.locbtn);

locbtn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

FusedLocationProviderClient fusedLocationProviderClient = 
LocationServices.getFusedLocationProviderClient(getApplicationContext());


Task task = fusedLocationProviderClient.getLastLocation();

task.addOnSuccessListener(new OnSuccessListener () {

@Override

public void onSuccess(Location location) {

if(location!=null) {

wargps.setText(location.getLatitude()+" "+location.getLongitude());

locbtn.setText("Got Location");

}}});

}

});

Android Picasso vs s33me code

I spent several hours tweaking my own loading of images into an Android ListView. The problem was that the images would not load until I scrolled the screen and even then the lag was unacceptable.

My program performed the following:

Download a non indexed list of geotag data that includes the image URL into ArrayList rowdatalist

Loop through the rows in rowdatalist and Async create the bitmap from the image URL in each row

The customRowAdapter for the ListView will have a ViewHolder that sets the holder.imageView from the bitmap decoded from the URL.

Essentially, this produces statements like the following:
holder.imageView = (ImageView) convertView.findViewById(R.id.row_image);
holder.imageView.setImageBitmap(rowdata.getBitmap());
This is from inside the object rowdata

public Bitmap getBitmap() {

if (bitmapurl != null && !bitmapurl.equals("")) {

new ImageLoadAsync(context).execute(bitmapurl);

} else {

// default image if nothing from url

bitmap = BitmapFactory.decodeResource(context.getResources(), R.drawable.war4a);

}

return bitmap;

}

This is the background thread portion of the Async call:

@Override

protected Bitmap doInBackground(String... urls) {
            
String surl = urls[0];

Bitmap bm = null;

try {

URL imageUrl = new URL(surl);

bm = BitmapFactory.decodeStream(imageUrl.openStream());

} catch (IOException e) {

e.printStackTrace();

bm = BitmapFactory.decodeResource(context.getResources(), R.drawable.war4a);

}

return bm;

}

This is just a portion of the cumbersome code. As an experienced programmer, I should have known not to reinvent the wheel, but I just could not help myself

At the end of the day, this line of code replaced all that nonsense

Picasso.with(context).load(rowdata.getBitmapUrl()).into(holder.imageView);



			

HTML / CSS Freeze Page Header

I want to freeze the title portion of the page so that it is always visible while the main list of images scrolls freely below. See an example at augmented reality geotags.
Below is my code. The "bottom" and "top" parameters seem to be the key; however, be advised that I have not yet tested this on a variety of screen configurations.

#titlepane {

float:left;

background-color: #ffffff;

width:100%;

padding:10px;

bottom:65%;

position: fixed;

box-shadow: 8px 8px 10px #999999;

z-index:2;

}


#scrollbelowtitle {

position:fixed;

float: left;

clear:left;

top: 35%;

padding: 10px;

height: 500px;

width: 100%;

overflow-y: scroll;

z-index:1;

}

Hydra Command Line Arguments on Lenovo Yoga Book/Debian Linux.

Example of Hydra command line arguments that seem to be running through the iterations.

sudo hydra -l myusername -P /usr/share/dict/rockyou.txt -o output.txt thetarget.com http-post-form "/login.cfm RetURL=%2FDefault%2Easp%3F:login_name=^USER^&password=^PASS^:S=logout myusername" -vV -f

Replace myusername with your user name

Replace target.com with yourwebsite.com

Replace login_name with yourwebsite's variable for user name (Hint: View form source code)

Replace password with yourwebsite's variable name for password (Hint: View form source code)

Do not let this run through completion or to success if target.com is not a website that you own, unless you want to go to jail.
