It's Hexadecimal isn't it? Wheres stephj when you need him?
Yeah, it's hex, but to convert it to any other format would still just be numbers. We need to figure out what the numbers mean. I did have a look at it earlier and fancy giving it a go. Not sure where to start so I'll just jump in and see what happens. (Later, after work)
Meh..... numbers.....
I'll pass.
If it were masonic/occult symbols I may be interested.

Maybe when converted to decimal the number refer to chapters from the book of revelations
A bit more juicy for you?
The answer is 42.

I must admit to having had a bit of a dabble at this, as it was plastered all over the daily papers today. Tried a bit of classic cypher stuff, but to no avail, yet.
If I find the location of the Holy Grail, I'll get back to you.
As I have already got the hex values from the screen shot above, typed into a text file, and if anyone else fancies a crack at it, it's attached here in order to save you having to punch the data in yourself.
Good Luck!
PS. 'Punch' is a reference to a mainframe machine's 80 column punched cards. Very old hat now, but old terms die hard!
PPS. Ever wondered why console screens, (Window's CMD.EXE)/(Linux Konsole shell), are always 80 columns across? Might the two be related?
The truth is out there. Literally. There's a pastebin of some computer code that resolves the puzzle.
The hex has to be turned into an .exe or some such sorcery. I'll track down a link...

It would also appear that the hex digits are 32 bit 80386 or later machine code, so lets do this step at least.
The following 'C' code takes the file HEXCODE.TXT and converts it to the binary file HEXCODE.BIN
HEXCODE.ZIP contains HEXCODE.BIN
Code:
#include <stdio.h>
main()
{
char hex[16];
char buffer[100];
int i;
FILE *in,*out;
if((in=fopen("hexcode.txt","r"))==NULL)
{
printf("Can't open input HEXCODE.TXT\n");
return(1);
}
if((out=fopen("hexcode.bin","wb"))==NULL)
{
printf("Can't open output HEXCODE.BIN\n");
return(1);
}
while(fgets(buffer,100,in))
{
sscanf(buffer,"%02X %02X %02X %02X %02X %02X %02X %02X %02X %02X %02X %02X %02X %02X
%02X %02X",
&hex[0],&hex[1],&hex[2],&hex[3],&hex[4],&hex[5],&hex[6],&hex[7],
&hex[8],&hex[9],&hex[10],&hex[11],&hex[12],&hex[13],&hex[14],&hex[15]);
fwrite(hex,1,16,out);
}
fclose(in);
fclose(out);
return(0);
}
This file can then be loaded into a dissassembler. The command line version of DEBUG.EXE has an inbuilt disassembler, but it can't cut it as it is only 16 bit. The freeware version of IDA being an excellent tool for the job. Once you have told it that the code is 32 bit and the code starts at offset 0, it reveals the following code. Time to brush up your 32 bit x86 assembler.

There are one or two things to note about this code. It appears to have been hand written, as it is does not carry the signature of a compiler. It has probably designed to run on a Linux OS distro, as there is no usual 'Windows' end/exit/return to the procedure, namely a RET instruction. Instead it uses an INT 80h interrupt. also note the DEADBEEF reference at 0x17
This code is used to decrypt a message hidden in the CYBER.PNG file itself, which is the image in the first post.

It's really obvious so I'm guessing you already checked that, but:

Yup thats where I am starting
http://pastebin.com/ciaXzHzY
Got that file from a Xoom build and tried to recompile again.
What source kernel is this exactly?
linux/usb/android_composite.h
Its already a part of 50x, are your paths set properly?
Check to see if your build path actually includes everything it should
this is the new tegra kernel from google, 2.6.39, working on dj steve server
And the new errors
http://pastebin.com/Lec1F2vt
Solved and onto new issues http://pastebin.com/XGBr8rFn
Ripped the kernel from another Tegra2 device, and ran the defconfig and it compiled, just waiting to hear if it works or not.
Did it worked? If you want maybe I could help a bit

We re-worked the kernel to add our stuff and came up with a bunch of errors, but after working at it, I'm down to just one error.

Okay, so I know a lot about nothing and a little about something, but curious why that has sections for definitions but they're commented out, therefore it's using the same definitions multiple times?
Most of them are the same, not sure if that'd matter, but others, such as this one, are defined differently three times.. Not sure if that means the first or the last is used..
{ "pclk", "hclk", 54000000, true },
What I would try, and you probably already have, is strip out all of the duplication leaving the correct/intended values, or fix the ifdef's so they aren't commented out and are being used.
Code:

Hi!
If you're beginning Java like me, then share your code here!
Simply use the code tags.
Here's my latest application:
Code:
package name;
import java.util.Scanner;
public class Name {
public static void main(String[] args) {
Scanner user_input = new Scanner(System.in);
String first_name;
System.out.print("Enter your first name: ");
first_name = user_input.next();
String surname;
System.out.print("Enter your surname: ");
surname = user_input.next();
String age;
System.out.print("How old are you: ");
age = user_input.next();
String full_name;
full_name = first_name + " " + surname;
System.out.println("You are " + full_name + "." + "You are also " + age + " " + "years old.");
System.out.println("Note that some of this information may not be true, since it it the information you or someone/something else provided.");
System.out.println("You got a problem with that?!?!");
System.out.println("Thank you for using my awesome Java application!");
}
}
So, post yours!!
Right. I see there aren't many people Beginning Java round here.

Nope. I had 1 semester of Java well over a year ago. I forgot most of it since I started c++, which I forgot also the day after the semester ended.
I was learning c#, but then i realized that it's a crap language and im not going to get anywhere using it, so i started learning Java, which i'm trying hard to remember, and as you have seen, i have.
Yea Java is the **** right now. C++ is good for windows only. I have to see if I can continue taking Java in college instead of C++. And it is so much easier than C++ or any C language for that matter.
I used to study Java but my college wants C++. I think Java is easier when it comes to GUI.

for(i=0;i<=oldlen;i++)
{
newstring=oldstring.substring(0,i)+insert+oldstring.substring(i);
if(newstring.length()==startlen)
System.out.print(newstring+"\n");
else
genanag(newstring,startstring.substring(oldlen+1,oldlen+2));
}
}
}
When you run it you get this :

COOL!
Unfortunately I'm not uo to that stage yet. Moving onto Joptionpane next, whatever that is.LOl. Where'dya learn Java.
Allow me to do some experimental BB Code programming!

I have been programming for years, originally in COBOL.
The ability to code in Java came from learning C#, from previously learning C++, itself from C. (Other languages include Fortran, 370 Assember, PC Assembler and RPG III/IV, but none of these have much in common with object orientated programming.)
While the C# and Java communities seem to take great delight in throwing brickbats at each other from their respective trenches, there is not really a great deal of difference between the two languages, not any that are worth getting upset about!
Right let's make it do something vaguely useful.......... This was originally coded in C# as a solution to the following post.
http://forum.xda-developers.com/showthread.php?t=1435629
ISO6346 defines the layout of serial numbers and the checksum digit for intermodal containers. (The 20 and 40 ft metal containers used to ship almost everything these days.) :- http://en.wikipedia.org/wiki/ISO_6346
This code takes the first ten characters of the serial number and calculates the checksum digit. The argument must be of the form ABCD123456 or there is no response:
Code:
public class ISO6346
{
public static void main(String[] args)
{
String Input = args[0].toUpperCase();
int i,j,k;
if(Input.matches("[A-Z]{4}[0-9]{6}"))
{
k=0;
for (i=0; i<10; i++)
{
j = Input.charAt(i);
if (j > 64 && j < 91)
k += ((j - 55) + (j - 56) / 10) << i;
else
k += (j - 48) << i;
}
k = ((k % 11) % 10);
System.out.print(Input.substring(0,4)+" "+Input.substring(4)+" "+k);
}
}
}
Results in:
Code:
C:\Program Files\Java\jdk1.6.0_23\bin>JAVA ISO6346 TOLU473478
TOLU 473478 7
C:\Program Files\Java\jdk1.6.0_23\bin>
Compare the result with the image in the top right of the Wikipedia page.......... and that concludes the case for the defense, Your Honour!
As my current Project is based on JSP, I'll share the crap I'm doing now :
Function for Inserting datas into database (Anyways the database should be connected before doing this [includes code] + --> Connection con = null; PreparedStatement ps = null
Code:
public boolean FunctionName(String name, String address, String phoneno)
{
boolean flag = false;
try {
ps = con.prepareStatement("insert into TABLE_NAME(FIELD_1,FIELD2,FIELD_3) values(?,?,?)");
ps.setString(1,name);
ps.setString(2,address);
ps.setString(3,phoneno);
ps.executeUpdate();
flag = true;
}
catch(Exception e) {
System.out.println("Error in Insertion"+e);
}
return flag;
}
+
HTML / JSP Design Page should be there to get values from user (Textbox)
+
JSP action page should be there to trigger action when user clicks the button on the design page.
Where would anyone here recommend starting to learn Java from? Online, books, classes? Just starting out and not sure which is the best place to go first? I have dl Java sdk and eclipse but that's about as far as I'm at.

Database Connection code (Mysql is discussed) :
Code:
package com.db; //Package name optional
import java.sql.*;
public class DbConnection()
{
Connection con = null;
PreparedStatement ps = null;
ResultSet rs = null; //ResultSet is useful for Select queries
public DbConnection() //Create a constructor
{
try {
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost/DATABASE_NAME","root",""); //I guess root is default in Mysql
}
catch(Exception e) {
System.out.println("Error in Connection"+e);
}
}
}

The best reference for Core Java (ie, Java SE) I'd recommend "The Complete Reference Java Seventh Edition (Or Fifth Edition) by Herbert Schildt"
And don't start studying Java using IDE (like Eclipse or Netbeans)
Start writing code using simple Notepad or Notepad++ and compile it in Command Prompt. This is the best way for freshers.

Thanks guys I'll look into both of these. I'm looking forwards to learning all i can. Fingers crossed

As Java used to be owned by Sun, before they themselves were bought by Oracle, there is a whole load of documentation beginning here:
http://docs.oracle.com/javase/
As well as here:
http://www.oracle.com/technetwork/java/javase/overview/index.html
The API documentation is useful when you need to find which method of which object you need to do the job.
Simple java code
one of first for math (ax^2+bx+c)
Code:
int a=2; //example
int b=3;
int c=4;
for (int i = 0; i<=100;i++){
if((a*(i*i)+b*i+c)==4)
system.out.println(i);
}
That is beyond me! If I had more time, I would be learning Java quicker.

Hi devs! I'm pretty noob in programming. While working on a simple Java program in Eclipse, related to formatting strings, I came around a problem where I'm not getting an output which is expected from the lines of code.
Here's the code:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
But I got this as output:
But from the code, the expected output is this, right??
Where did I go wrong??
Hi, you could try using the following. I think it should work but I also have limited knowledge of Java.
Set these variables inside for loop
int square = i*i
int cube = i*i*i
Replace the f.format line and the print output with the following.
System.out.format("%10d%10d%10d", i, square, cube)

That worked Veeman! :good: :victory: But I had to add a \n to get a new line. Thanks a ton! cheers!
Btw, can you give a detail about that?? about, why it happened?? Thanks again..

I think your problem was just using the format wrong.
Sent from my Nexus 7 using Tapatalk HD
Here's why your original code produces the results it does. 'veeman' is correct in that is not the way you would normally use a formatter. Instead you would use the format() method of System.out to present the output how you want it, as shown in post #2 above.
Your original code has created a Formatter with the default constructor. i.e. nothing passed as parameters in the call to create the 'new' object.
From the documentation in: -
http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Formatter.html
we have: -
public Formatter()
Constructs a new formatter.
The destination of the formatted output is a StringBuilder which may be retrieved by invoking out() and whose current content may be converted into a string by invoking toString(). The locale used is the default locale for this instance of the Java virtual machine.
Click to expand...

Therefore, the destination of this object, (i.e. where its output is going to), is the Formatter's own internal appendable Stringbuilder object.
By using f.format(....) you are writing to the end of this stringbuilder object.
This explains why you are printing out a string that increases by the next term each time.
To make your code use the formatter correctly, you need to do something like this:
Code:
import java.util.*;
public class FormatDemo {
public static void main(String[] args) {
Formatter f=new Formatter();
for (int i=0;i<10;i++) {
f.format("%d\n",i*i*i);
}
f.out();
}
}
Code:
C:\PROGRA~1\Java\JDK17~1.0_0\bin>javac FormatDemo.java

It's fine here - it's not related to phones so doesn't belong in any of the other Q&A or app development forums.
I'm a little surprised by this though. I can see what it's doing, but have no idea why it would. Admittedly I'm not au-fait with Java yet, but I know enough about C based languages to say, "eh?"
Edit: I take that back - just read your post properly
Yeah okey. I got it.. Thanx everyone for the reply. Actually there is another careless mistake in the program I pasted above. But anyway good for me that you guys knew what I was trying to ask. Thanx again! :highfive:
Hello,
my code dont give me something back, no error, nothing.
the "global_actions_view_cover.xml" is in "layout-sw360dp-xhdpi".
whats wrong with my code?
Code:
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
XResources.hookSystemWideLayout("android", "layout", "global_actions_view_cover", new XC_LayoutInflated() {
@Override
public void handleLayoutInflated(LayoutInflatedParam liparam) throws Throwable {
XposedBridge.log(LOG_TAG + "global_actions_view_cover");
}
});
}
thanks for helping
That'll only be inflated if your device's width is higher than 360dp and it's an XHDPI device. Not sure what will happen if there are multiple matches.
See this for more info.
