    Making LaTeX Beamer Presentations

    I came across this nicely compiled page on :
    how to make Latex Beamer Presentations

    If you want to create overhead presentations (á la Powerpoint) with LaTeX, you can do so by using Beamer class, which creates surprisingly professional and sophisticated documents that you can then display using any pdf viewer (e.g., such as Adobe Acrobat). The advantage of using LaTeX over a program like Powerpoint is that it doesn't require expensive software for either creating or displaying your presentation; it thus makes the presentation truly "portable".

    Greasemonkey script to Replace URLs in webpage

    Yesterday night i made this script which replaces urls with their alternatives in a webpage. What r its usage :

    • Ad blocking (Replacing such URLs with blank so that clicking them will result in nothing.
    • Unblocking some sites :) . At many places sites are just blocked by url names so it replaces them with ip.(for example i did same for youtube as its blocked in my college). you can modify script to include more such urls.
    You will need firefox with Greasemonkey extension installed to use this script.
    Here is the script : Right Click to install

    Java JRE/JDK installation

    To verify that the installation was successful, execute

    java -version

    The output should look something like this if everything is well

    java version "1.5.0_05"
    Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
    Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode)

    If the version does not match what you just installed then you might have JRE/JDK installed previously

    Multiple JRE/JDK installed

    If you have multiple JRE or JDK installed (e.g. 1.5.0 and 1.4.2) and want/need to switch between them, you can use update-alternatives to do so.

    Example: Choosing which java executable to use:

    update-alternatives --config java

    Example: Choosing which javac executable to use:

    update-alternatives --config javac

    And so on in that fashion for the remaining executables related to Java. You can look in /etc/alternatives to see what one can configure with update-alternatives.

    It's not too late to be a genius

    Nice article from creating passionate users :

    In the web/tech world (and many other domains), it seems the Big Ideas belong to the Young. Barely 27, David Heinemeier Hansson, creator of the Ruby on Rails framework, has changed the world and given the Ruby language a reason to live. Then there's Caterina and Stewart, creators of Flickr. Then there's Larry and Sergey, the "boys" behind Google, and Jeff Bezos was just 30 when he founded Amazon.


    It's never too late to make a difference. Just...keep...trying s***. And remember the quote from the 90-something woman who, when asked about her regrets said, "If I'd known I was going to live this long, I'd have taken up the violin at 60. I'd have been playing for almost 40 years by now..."

    The Story Behind These Company Names

    Here are some interesting encounter how these companies got their name :...

    Apache - It got its name because its founders got started by applying patches to code written for NCSA’s httpd daemon. The result was ‘A PAtCHy’ server -– thus, the name Apache.

    CISCO - Its not an acronym but the short for San Francisco.

    Hewlett-Packard (HP) - Bill Hewlett and Dave Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett, and the winner was NOT Bill…the winner was Dave.

    Apple Computers - Steve Jobs was three months late in
    filing a name for the business because he didn’t get any better
    name for his new company. So one day he told to the staff: “If
    I’ll not get better name by 5 o’clock today, our
    company’s name will be anything he likes…” So at 5
    o’clcok nobody come up with better name, and he was eating Apple
    that time… so he keep the name of the company ‘Apple Computers’.

    Enabling and disabling services during start up in GNU/Linux

    In any Linux distribution, some services are enabled to start at boot up by default. For example, on my machine, I have pcmcia, cron daemon, postfix mail transport agent ... just to name a few, which start during boot up. Usually, it is prudent to disable all services that are not needed as they are potential security risks and also they unnecessarily waste hardware resources.

    The start-up scripts are stored in the '/etc/init.d/' directory. So if you want to say, enable apache webserver in different run levels, then you should have a script related to the apache webserver in the /etc/init.d/ directory. It is usually created at the time of installing the software.
    This article describes how can we enable or disable different services during boot in different kind of distros like Redhat, Debian, Gentoo

    The Best Places To Launch A Career

    The top 50 employers for new college grads

    It's now clear, for instance, that to attract the best and the brightest, companies are no longer competing only with others in their industry. More open to career experimentation than previous generations, college grads are applying across a swath of industries. The result: No. 4-ranked Goldman Sachs (GS ) could just as easily be vying with No. 43 Teach for America and No. 13 Google (GOOG ) as with No. 9 JPMorgan (JPM ) and No. 22 Lehman Brothers (LEH ) for the very same applicant. The intensely competitive market for top young talent means companies have to fine-tune their game.

    An Introduction to AJAX

    AJAX (Asynchronous JavaScript and XML) is the latest boom in the Web development world. AJAX helps developers narrow the gap between desktop and web applications — Google Earth, Flicker and MS Outlook Express Web Version are some of the applications powered by AJAX.

    Asynchronous means that you can make a request to a server and perform other actions while the server is processing your request -- and on the arrival of the response required actions can be performed -- as opposed to conventional web applications, in which the user has to sit back and stare at the blank screen while the server is processing the request.

    India Joins China in Censoring Websites

    "On the directions of the government of India, Indian ISPs have started censoring and blocking web properties. This was first noticed by Indian bloggers and upon inquiring with their respective ISPs, the actions are confirmed. Unfortunately, Blogspot and TypePad are the targets till now."
    There's an ongoing discussion of the censorship on GoogleGroups. The rediff.com coverage linked above indicates that the blocking is based on a list issued by India's Department of Telecommunications.
    This is a list of ISPs already known to be blocking these domains.
    India's Department of Telecommunications (DoT) passed an order to ISPs Friday to block several websites. The list is confidential. Indian ISPs have been slowly coming into compliance. SpectraNet, MTNL, Reliance, and as of Monday afternoon, Airtel. State-backed BSNL and VSNL have not started yet but likely will soon.
    The known list of blocked domains is *.blogspot.com, *.typepad.com and geocities.com

    Dual Processor vs Dual Core

    It has always been a frequent question "Will I benefit from multiple processors?" With the growing popularity of dual core processors, the topic is more important than ever! Will multiple processors or a dual core processor be beneficial, and what are the differences between them? These are the questions this article will attempt to lay to rest.

    A major question for some people getting ready to buy a high-end system is whether they want or need to have two processors available to them. For anyone doing video editing, multi-threaded applications, or a lot of multitasking the answer is a very clear 'yes'. Then the question becomes whether two separate processors (as in a dual Xeon or Opteron system) is the way to go, or whether a single dual-core CPU (like a Pentium D or Athlon64 X2) will do just as well. Dual CPU vs dual core -- which is better?!

    It's 2025. Where Do Most People Live?

    It's 2025. Where Do Most People Live? from PhysOrg.com

    Researchers at the Center for Climate Systems Research (CCSR), a part of The Earth Institute, have developed a high-resolution map of projected population change for the year 2025.

    [...]

    It's 2025. Where Do Most People Live?

    The map indicates that the greatest increases in population density through 2025 are likely to occur in areas of developing countries that are already quite densely populated. In addition, the number of people living within 60 miles of a coastline is expected to increase by 35 percent over 1995 population levels, exposing 2.75 billion people worldwide to the effects of sea level rise and other coastal threats posed by Global warming

    How to create a patch

    Generating patches, files containing the difference between files, is the domain of diff programs.
    Creating Patch :

    diff -Naur olddir newdir > new-patch


    Note: the symbol > will redirect the output to the file new-patch.

    To apply the patch
    go to olddir and do :

    patch -p1 <new-patch

    And if you want some files to be excluded from doing a diff use -x option like

    diff -Naur -x *.o olddir newdir > new-patch
    this will exclude .o files when doing a diff

    Searching with find

    The find command is one of the darkest and least understood areas of Linux, but it is also one of the most powerful. The biggest problem with find is that it has more options than most people can remember -- it truly is capable of doing most things you could want.

    The most basic usage is this:

    find -name "*.txt"

    That query searches the current directory and all subdirectories for files that end in .txt.

    The Myth of the New India

    "An NYT op-ed on The Myth of the New India reports that only 1.3M Indians are participating in the so-called new economy of BPO, leaving 400M have-nots without a piece of the pie. Despite recent gains, nearly 380M Indians still live on less $1 a day, setting the stage for rural and urban conflict."

    From the article: "No labor-intensive manufacturing boom of the kind that powered the economic growth of almost every developed and developing country in the world has yet occurred in India. Unlike China, India still imports more than it exports. This means that as 70 million more people enter the work force in the next five years, most of them without the skills required for the new economy, unemployment and inequality could provoke even more social instability than they have already."


    Few Comments :
    A Dollar fetches a lot of things in India, and i'm surprised that a lot has been assumed and written about without checking the facts. as of today, a dollar equals about Ruppees 45.84 (that was yesterday's rates). a Dollar fetches a lot of stuff, in fact i will give 2 examples - one for the metropolitan poor man with a dollar and the poor man in the rural india

    Wikipedia 3.0: The End of Google?

    Semantic Web + Wikipedia’s Ontoworld = Ultimate Answer Machine

    Here is an intereseting article

    The Semantic Web (or Web 3.0) promises to “organize the world’s information” in a dramatically more logical way than Google can ever achieve with their current engine design. This is specially true from the point of view of machine comprehension as opposed to human comprehension.The Semantic Web requires the use of a declarative ontological language like OWL to produce domain-specific ontologies that machines can use to reason about information and make new conclusions, not simply match keywords.
                                         However, the Semantic Web, which is still in a development phase where researchers are trying to define the best and most usable design models, would require the participation of thousands of knowledgeable people over time to produce those domain-specific ontologies necessary for its functioning.

When the eBay auction for the last of the page's real estate ends tomorrow at 1:42 pm EST, Tew will have earned much more than $1 million.

    India Awakens

    Fueled by high-octane growth, the world's largest democracy is becoming a global power. Why the world will never be the same
    Even if you have never gone to India--never wrapped your food in a piping-hot naan or had your eyeballs singed by a Bollywood spectacular--there is a good chance you encounter some piece of it every day of your life. It might be the place you call (although you don't know it) if your luggage is lost on a connecting flight, or the guys to whom your company has outsourced its data processing. Every night, young radiologists in Bangalore read CT scans e-mailed to them by emergency-room doctors in the U.S. Few modern Americans are surprised to find that their dentist or lawyer is of Indian origin, or are shocked to hear how vital Indians have been to California's high-tech industry. In ways big and small, Indians are changing the world.

    Inside the Linux Boot Process

    This article explores the Linux boot process from the initial bootstrap to the start of the first user-space application. Along the way, you'll learn about various other boot-related topics such as the boot loaders, kernel decompression, the initial RAM disk, and other elements of Linux boot.

    When a system is first booted, or is reset, the processor executes code at a well-known location. In a personal computer (PC), this location is in the basic input/output system (BIOS), which is stored in flash memory on the motherboard. The central processing unit (CPU) in an embedded system invokes the reset vector to start a program at a known address in flash/ROM. In either case, the result is the same. Because PCs offer so much flexibility, the BIOS must determine which devices are candidates for boot. We'll look at this in more detail later.

    When a boot device is found, the first-stage boot loader is loaded into RAM and executed. This boot loader is less than 512 bytes in length (a single sector), and its job is to load the second-stage boot loader.

    When the second-stage boot loader is in RAM and executing, a splash screen is commonly displayed, and Linux and an optional initial RAM disk (temporary root file system) are loaded into memory. When the images are loaded, the second-stage boot loader passes control to the kernel image and the kernel is decompressed and initialized. At this stage, the second-stage boot loader checks the system hardware, enumerates the attached hardware devices, mounts the root device, and then loads the necessary kernel modules. When complete, the first user-space program (init) starts, and high-level system initialization is performed.

    Vim tips: Using viewports

    A really useful feature in Vim is the ability to split the viewable area between one or more files, or just to split the window to view two bits of the same file more easily. The Vim documentation refers to this as a viewport or window, interchangeably.
    You may already be familiar with this feature if you've ever used Vim's help feature by using :help topic or pressing the F1 key. When you enter help, Vim splits the viewport and opens the help documentation in the top viewport, leaving your document open in the bottom viewport.

    Learn how to comment

    This wikipedia tells about different commenting styles and how they can be helpful while programming.
    http://en.wikipedia.org/wiki/Comment#Summary

    Comments could summarise code or explain the programmer's intent. This is called the why rather than how approach. The two are often close, but not always. According to this school of thought, restating the code in plain English may be a waste of time; the need to explain the code may be a sign that it is too complex and should be rewritten.

    "Don't document bad code – rewrite it" (The Elements of Programming Style, Kernighan & Plauger).
    "Good comments don't repeat the code or explain it. They clarify its intent. Comments should explain, at a higher level of abstraction than the code, what you're trying to do." (Code Complete, McConnell)

    graph plotting with gnuplot

    Gnuplot is a free, command-driven, interactive, function and data plotting program.
    Here i' m providing a quick reference guide for plotting graphs (as many of us don't bother to go in detailed documentation).
    On Unix/Linux systems start Gnuplot by simply typing:
    gnuplot

    first the formal syntax :

    plot {[ranges]}
    {[function] | {"[datafile]" {datafile-modifiers}}}
    {axes [axes] } { [title-spec] } {with [style] }
    {, {definitions,} [function] ...}

    To plot functions simply type: plot [function] at the gnuplot> prompt
    gnuplot> plot sin(x)
    gnuplot> splot sin(x*y/20)
    gnuplot> plot sin(x) title 'Sine Function', tan(x) title 'Tangent'


    Now for plotting data points firstly data points should be written in text file with axis ranges as columns.Data files should have the data arranged in columns of numbers. Columns should be separated by white space (tabs or spaces) only, (no commas). Lines beginning with a # character are treated as comments and are ignored by Gnuplot. A blank line in the data file results in a break in the line connecting data points. '
    Plotting a graph from data file "plot.data" , do
    gnuplot>plot "plot.data"

    Now customizing the plot :



    set xlabel "x-axis data"

    # will set a label "x-axis data" in graph
    set ylabel "y-axis data"

    set title "x vs y"
    # will set title for graph
    set xrange [0.001:0.005]
    # Change the x-axis range:
    set yrange [20:500]
    # Change the y-axis range:
    set logscale
    # plot using log scale
    set autoscale
    #let gnuplot determine ranges
    plot "file.data" with lines
    #will join data points with lines
    plot "file.data" smooth csplines with lines
    #will join plot graph using smooth curves
    Gnuplot can mathematically modify your data column by column:
    to plot sin( col.3 + col.1 ) vs. 3 * col.2 type:

    plot 'force.dat' using (3*$2):(sin($3+$1))

    To print graph (this will store graph in post script(.ps) file do this before plotting graph:

    set output "graphs.ps"
    set terminal postscript
    plot "file.data" using lines


    This will save the graph in graph.ps
    For more help type 'help' in gnuplot mode :
    gnuplot>help

    Phishing

    Now a days, phishing cases had increased so here is brief writeup to give insight a about phishing . Read Wikipedia to know about phising examples.
    Phishing is a technique used to gain personal information for purposes of identity theft, using fraudulent e-mail, instant messages that appear to come from legitimate site. These authentic-looking messages are designed to fool recipients into divulging personal data such as account numbers and passwords, credit card numbers and Social Security numbers.

    why phishing works :

    • Lack of knowledge
    • Visulal deception : Phishers use visual deception tricks to mimic legitimate text, images and windows.
      • Visually deceptive text.: Users may be fooled by the syntax of a domain name in “typejacking” attacks, which substitute letters that may go unnoticed (e.g. www.paypai.com uses a lowercase “i” which looks similar to the letter “l”, and www.paypa1.com substitutes the number “1” for the letter “l”). Phishers have also taken advantage of non-printing characters [25] and non-ASCII Unicode characters [26] in domain names.
      • Images masking underlying text. One common technique used by phishers is to use an image of a legitimate hyperlink. The image itself serves as a hyperlink to a different, rogue site.
    • Bounded attention
      • Lack of attention to security indicators: When users are focused on their
        primary tasks, they may not notice security indicators or read warning messages. The image-hyperlink spoof would ve thwarted if user noticed the URL in the status bar did not match the hyperlink image, but this requires a high degree of attention.

    Techniques used within Phishing emails:
    • Official looking and sounding emails
    • Copies of legitimate corporate emails with minor URL changes
    • HTML based email used to obfuscate target URL information
    • Standard virus/worm attachments to emails
    • A plethora of anti spam-detection inclusions
    • Crafting of “personalised” or unique email messages
    • Fake postings to popular message boards and mailing lists
    Preventing Phising :
    • If you get an email that warns you, with little or no notice, that an account of yours will be shut down unless you reconfirm billing information, do not reply or click on the link in the email. Instead, contact the company cited in the email using a telephone number or Web site address you know to be genuine.
    • Never respond to HTML email with embedded submission forms. Any information submitted via the email (even if it is legitimate) will be sent in clear text and could be observed.
    • Avoid emailing personal and financial information. Before submitting financial information through a Web site, look for the "lock" icon on the browser's status bar. It signals that your information is secure during transmission.
    • Before signing to a page check for URL(make sure it is valid page, there may be some deceptive text there,like i in place of l). Or yo can try first enteing wrong password so a nonvalid page (if it is accessing information and is redirecting to legimate page to avoid being caught) will redirect you to correct page.
    • Switc your browser: use one with anti-phising agent (like firefox)

So far, the site has been a great way to bring together people such as Prasad Kaledhonkar, who has a clue about what the white patterns emerging on tomato plant leaves are; farmer's daughter Niyatee Nilesh, who wants advice on buying agricultural land; and Shirish, from rural Maharashtra, who wants to learn about using waste water from the school kitchen to irrigate gardens and crops.

    Little tweaks with javascript : Bookmarklets.

    A bookmarklet is a snippet of Javascript that can be bookmarked (or saved as a favorite) inside your web browser. Bookmarklets can enhance web pages, add special functionality using javascript which is supported by most browsers today and make your browsing experience a lot more efficient by offering one-click access. I will first start with basics.
    Consider a simple javascript :

    • javascript:alert('You clicked on the page');
    When you type this in browsers location bar then it will show a message box with "you clicked on the page" message. Now change this slightly :
    • javascript:function ab(){alert("hello") ;};void(setInterval(ab,1));
    Now this will repeatedly pop-up the message box in every 1-sec interval. Though this is of no use i'm just telling this to explain basics of javascript.

    Now filling form with javascript :
    • javascript:function ab() {document.forms[0].login_username.value="someText" ; } ab() ;
    Now this javascript will fill the value "someText" in field login_username of form in html page.
    And lets try to take some user-input :

    • javascript:function ab() {q=document.getSelection(); if(!q) {void(q=prompt('Text :',''))} else alert(q)} ab();
    Now this javascript will first check if some text is selected on page. If no text is selected it will prompt user for text else will show an message box with selected text. Now we can put this script to some good use : like

    • javascript:function ab(){q=document.getSelection(); if(!q){void(q=prompt('Search Text at My Blog: ',''))} location.href="http://www.technorati.com/search/ "+q+" linux?from=http://burad.blogspot.com "; }; ab();
    Now this will search the selected text on my blog or if text is not selected than prompt user for text.

    An equivalent script for searching on wikipedia is :
    • javascript:(function(){q=document.getSelection(); if(!q){void(q=prompt('Wikipedia keywords:',''))}; if(q) location.href= 'http://en.wikipedia.org/w/wiki.phtml?search='+escape(q)})()
    Now you can bookmark this script in toolbar so every tim you click on button in toolbar it will execute javascript. For example Drag this to your firefox bookmark toolbar :


    Search Burad's Blog
    Or for wikipedia
    Search Wikipedia

    Some more bookmarklets :
    Scale Images

    Sort Table

    Transpose Table

    Show Password

    So in a way they are different from bookmarks and provides extra functionality through power of javascript. Here are some more javascript bookmarklet
    You can view source for each bookmarklet by viewing page source .
    You can find more bookmarklets at : http://www.squarefree.com/bookmarklets/

    See this helpful screencast on bookmarklets.

    Some More Example at Wisdombay

    Updated : For changing documenet backgrounds :
    Change to Red
    Change to green
    Change to blue
    This may not work with pages using css

    Splash image in GRUB

    The splash image is the image shown in the background when GRUB (the GRand Unified Bootloader) is displaying the list of operating systems you can boot.

    Creating image

    1. Start the GIMP.
    2. Click on File->New or type Ctrl+N
    3. In the new image dialog, change Width to 640 pixels and Height to 480 pixels. (The image should be of size 640x480 pixels.) Now click OK.
    4. Create the image which you would like to be the splash image. It's quite fun to experiment with the various tools of the GIMP!
    5. After you have finished creating the image, hit Alt+i or right click on the image and click on Image->Mode->Indexed...
    6. In the Indexed Color Conversion dialog that appears, click on the radio button "Generate optimal Palette" and in "# of colors" enter 14. Click OK.(The image should be of only 14 colors)
    7. Now right-click on the image and click on File->Save As...Save the file as ImageName.xpm in a directory of your choice.
    You can also pickup an image and convert to required format by ImageMagik:
    convert -resize 640x480 -colors 14 picture.jpg ImageName.xpm

    Installing the Image

    • gzip ImageName.xpm
    • mount /boot
    • mv ImageName.xpm.gz /boot/grub/
    In the /boot/grub/grub.conf you have to point splashimage to newly created image i.e

    # Splash Image
    splashimage=(hd0,0)/grub/ImageName.xpm.gz

    Now you just need to reboot !!

    Here is my boot splash screen: I just added my name and Gentoo logo :

    This is converted to jpeg. As blogger doesn't support xpm images.




    And some others :Some splash images
