Google Phone Confirmed By HTC Insider

On the software side, they're going to build a special version of Google Maps (complete with GPS), as well as have Gmail and Calendar compatibility. It's most likely going to have Google Docs compatibility too, but that wasn't specified. What's even cooler is that Google Talk, their free VoIP app, will be part of the suite. The OS could be Windows Mobile 6, or it could be a Linux-based OS, which would be even more interesting

Principle of Software Development

I have list down some principles of software development which I have learned from my previous experience with projects,people and books.

1. Quality is #1: "Just say no" when you are asked to speed up testing, ignore few bugs, or code before agreeing on a set of requirements.
2. Production and quality are inversely related. Higher the quality lower the production and vice versa.
3. Never loose sight with customers/users: It is very important to understand the actual need of the software
4. Prioritize Requirements
5. Use strict penalty for late delivery
6. Build the right feature in prototype
7. Changes during development is inevitable
8. Don't ignore technology
9. Use Documentation standard
10. Poor requirement mean poor cost/time estimation
11. Don't reinvent the wheel
12. Keep it Simple
13. Developers cannot be testers
14. Good management is more important then good technology
15. Don't set unrealistic deadlines
16. Save Everything

How to install SVN Server

http://www.excastle.com/blog/archive/2005/05/31/1048.aspx


http://sourceforge.net/project/downloading.php?groupname=tortoisesvn&filename=TortoiseSVN-1.4.4.9706-win32-svn-1.4.4.msi&use_mirror=internap

I downloaded following file first:

Please install version controlling on our local server. Also tell me can we install the SVN on our webserver?

Another claim to unlock iPhone in next 48 hours

http://www.iphonesimfree.com/

Mansi:

Go to the college. See the guy who claim he has iPhone, See it with your eyes and also ask him if you can make a call with it. Ask the proce he paid.

In USA they are fighting to unlock iPhone and still not able to.

MySql DeadLock!!!!

I was thinking before that i will never find situations like deadlock. But today i get trapped

What happened i was working in mysql while restoring database from backup "which was in write lock" i found need to kill the process. when i do so "kills the process but never release lock" database become of no use because i cant run query "use table" here how i solve it


try 1.

i run the mysql with -A option

now i was able to use table but even execution of query "unlock tables" was not solution as other queries was already in process

try 2

i try to find which queries are in process and which process is holding lock

ps was of course not a solution

so i found "show processlist" which give me all details about the queries in queue with pid now simply typing kill from sql prompt solves the problum

Windows server 2003 Backdoor

By default a Windows 2003 Server does only allow 2 simultaneous terminal server connections for remote management. "Log Off" closes the Session and releases the connection, but "Disconnecting" such as hitting the "X" to close the Remote Desktop Client leaves your session running and leaves your connection active, so that you can reconnect if your connection information hasn't changed. But what to do if your connection information has changed and you can't reconnect and the second connection is also not available?

There is one backdoor which can be used. Since Windows 2003 there is a little known feature which helps in a "too many connections" situation. The Remote Desktop client offers an option which allows you to connect to the console. This gives you a 3rd connection. If someone is logged into the console you have to have the sufficient permissions then the session will be logged out and you can log in. If nobody is logged into the console it will let you log in.

Start -> Run -> CMD
mstsc -v:x.x.x.x /console

x.x.x.x IP of server

You will be logged in to server as normal and if you want to disconnect the bad sessions simpley on end task click on user , select user you want to disconnect and click disconnect



Older versions of the client (i.e. windows 2000) seem to ignore the -v and pop up a connection window. Use the IP number, not the hostname, to start the connection. You will continue to get the too many services error if you use the hostname.

iPhone - I like the iPhone

I liked the user interface of the phone. I think this will definitely raise the level for others and for next couple of years we will see next generation mobile phones.

Sample .mac web gallery

http://gallery.mac.com/emily_parker

I am sure we can learn/Copy lots of stuff out of this.
Some initial thoughts,
1. I notice they are not calling events every time the scrollbar is moved rather they resize the image after every n sec on the basis of the current scroller size. This way they do not make script heavy. I like the idea.
2. No Flash
3. I really found the mosaic view useful.
4. I love the way they had implemented the album viewing with changing pictures with little scrollbar movements. Love that. I had never seen that before in a web application.
5. Either you do a right click or left on an image, it brings the image to full size.
6. Overlay to write comments on the image. Also notice the shadow created by overlay itself

am very excited to open this on iPhone Safari browser and see the result. I am sure it will run on it.

FYI following are the major library used in iWeb:

Also if you noticed they are using scriptaculus and prototype.js

innoDB v/s MyISAM

three must conditions for setting forign key

In order to set up a foreign key relationship between two MySQL tables, three conditions must be met:

1. Both tables must be of the InnoDB table type.
2. The fields used in the foreign key relationship must be indexed.
3. The fields used in the foreign key relationship must be similar in data type.

The indepth of Random

generate a bit string using Random(0,1) (the length of the bit string should be ceil (lg(b-a+1)) )...
e.g. random(3,8) means we have to generate a random bit string of length ceil lg 6 which is 3... now if the decimal value of the generated bit string is > 8-3 (i.e if the bit string is either 111, 110) then repeat the procedure... finally return 3 + [decimal val. of generated bit string]...

random(a,b)
{
int dec_val = b-a+1;
while(dec_val > b-a)
{
dec_val = 0;
for j = 1 to ceil(lg(b-a+1))
dec_val = 2*dec_val + random(0,1)
}
return dec_val+a;
}

expected running time calculation: here n is b-a+1

T(n) =
Pr{getting past while loop first time}*lg n
+ Pr{getting past while loop after 2 try}*(2 lg n) + .....

Pr{getting past while loop first time}
= Pr{bit string of length ceil(lg(b-a+1)) has value <= b-a}
= p

now p >= 0.5 (can u see why?)
therefore 0.5 <= p <= 1 and p can be computed but we don't need its value to perform the asymptotic analysis...

T(n) = p(lgn) + (1-p)p(2lg n) + (1-p)^2*p(3 lg n) + .....
= p(lg n)(1 + 2(1-p) + 3(1-p)^2 + 4(1-p)^3 + ... )

now 1 + 1-p + (1-p)^2 + (1-p)^3 + .... = 1/p
differentiating w.r.t p we get 1 + 2(1-p) + 3(1-p)^2 + ... = 1/p^2

therefore T(n) = (lg n)/p

which is O(lg n) or O(lg (b-a+1)) (since 0.5 <= p <= 1, that is p cannot be arbitrarily small)

MySQL

I have configured the mysql data directory to /mnt/mysql_db

You can immediately start insert to the database. It will automatically stored in the mnt folder

To install mysql
type : yum install mysql php-mysql mysql-server

To find config file
whereis my.cnf

To modify data directory
Edit my.cnf

To check disk space
use : df or du

Simple hash function

h(x) = sum( a[0] + a[1] + ... a[n-1] )
-allowing overflow

then bucket = h(x) / prime number near 5 million

use linked list off has table of 5 million buckets...

like struct {
KEY char[21]
PVOID next; 4 byte pointer
}

generate random 10 million 20 char 'KEYS' ... it doesn't matter if they are
readable...just 0..255 in value per BYTE.


I'll want to review the code after your test.

We should get 1 million / second or higher...just my guess.

This should be in C/C++ not C# or other.

Float number handling in Shell

I was having hard time using float number in shell programming.
Shell treat any number with . as a string. Then I got a trick to use bc ( binary calculator):

Usage:
num="echo $strnum | bc"
