Recover deleted file on Linux

2011-11-22T21:54:00.001-08:00

If you deleted a file on linux based OS accidentally, and want to recover it, lsof command may help you.

lsof is a Linux tool which can show open files and network connections, and even recover deleted files.

If you have ever deleted a file by mistake; been clearing up log files, or just used rm without thinking, there is a way of recovering that deleted file. For example, to recover a missing access_log used by Apache you can search for it via this command:

$ lsof | grep access_log

which output will be similar to:

httpd 26120 apache 42w REG 253,0 5852 12222531 /apachelogs/access_log (deleted)

The key word to look for here is deleted in brackets. The good news is a process (26120) still has the file open and without this process keeping the file open we would have lost the file permanently. So, with the Apache daemon helping us out we can view the missing info by looking inside the proc filesystem, the process id (26120), and finally in the file descriptor (fd):

$ cat /proc/26120/fd/42

This outputs the contents of my deleted access_log which shows the data is still there. All you need to do now is simply redirect the contents back to /apachelogs/access_log, like this:

$ cat /proc/26120/fd/42 > /apachelogs/access_log

Now you have recovered your access_log with all the data back to its original location. (You should also restart Apache). lsof can do much more, however, this is one example which could save the day.

Feel free to share other useful example of lsof here (in comments).

Hacking Firefox : Useful Addons

2011-09-20T23:05:00.000-07:00

After using firefox for almost 8 years, I think that there are so many firefox Addons without which my life wouldn't be so comfortable. In the progression of Hacking firefox to make browsing easy, here are few most used Firefox addons:

Firebug : Firebug integrates with Firefox to put a wealth of development tools at your fingertips while you browse. You can edit, debug, and monitor CSS, HTML, and JavaScript live in any web page.

YSlow : YSlow analyzes web pages and why they're slow based on Predefined & Custom rules for high performance web sites.

Pagespeed : Very Similar to YSlow provided by Google.

ColorZilla : a color picker, which is used to find any color code just by hovering mouse.

Xmarks Sync : is a bookmarking add-on. Keep your bookmarks, passwords and open tabs backed up and synchronized across computers and browsers.

GreaseMonkey : Customize the way a web page displays or behaves, by using small bits of JavaScript. Read Introduction to GreaseMonkey for a kick Start.

FoxClocks : FoxClocks lets you keep an eye on the time around the world - or just your local time - by putting small clocks in your statusbar.

AdBlock Plus : Annoyed by adverts? Troubled by tracking? Bothered by banners? Install Adblock Plus now to regain control of the internet and change the way that you view the web.

ChatZila : A clean, easy to use and highly extensible Internet Relay Chat (IRC) client.

Cookies Manager+ : Cookie manager that allows view, edit and create new cookies. It also allows show extra information about cookies and allows edit multiple cookies at once, as well as backup/restore them.

!(How to Kill PHP Performance)

2011-08-26T21:33:00.000-07:00

Wrap sting in single quote instead of double quote As PHP searches variable inside "..." but not in '...'
echo is faster than print print returns valus on success which degrades the performance.
Use echo‘s multiple parameters (or stacked) instead of string concatenation
Use pre-calculations set the maximum value for your for-loops before and not in the loop. ie: for ($x=0; $x < count($array); $x)
Unset or null your variables to free memory, especially large arrays.
Use require() instead of require_once() where possible
Use full paths in includes and requires less time spent on resolving the OS paths.
Close your database connections when you’re done with them.
Avoid use of @ Error suppression with @ is very slow.
Methods in derived classes run faster than ones defined in the base class.
Use pre-increment over post-increment
Use strict code, avoid suppressing errors, notices and warnings thus resulting in cleaner code and less overheads.
Avoid PHP scripts (unless cached) compilation on the fly every time you call them. Install a PHP caching product (such as APC, memcached or eAccelerator or Turck MMCache) to typically increase performance by 25-100% by removing compile times.
Try to use static pages
PHP scripts are be served at 2-10 times slower by Apache httpd than a static page.
else if statements are faster than select statements aka case/switch.
In OOP, declare a method as static, if it can be . Speed improvement is by a factor of 4.
$row[’id’] is 7 times faster than $row[id], because if you don’t supply quotes it has to guess which index you meant, assuming you didn’t mean a constant.
Use
$_SERVER[’REQUEST_TIME’] instead of time() or microtime() when script starts
When parsing with XML in PHP try xml2array, which makes use of the PHP XML functions
Use isset where possible in replace of strlen. (ie: if (strlen($foo) < 5) { echo “Foo is too short”; } vs. if (!isset($foo{5})) { echo “Foo is too short”; } ).
Incrementing an object property (eg. $this->prop++) is 3 times slower than a local variable.
Incrementing an undefined local variable is 9-10 times slower than a pre-initialized one.
Use ip2long() and long2ip() to store IP addresses as integers instead of strings.
When using header(‘Location: ‘.$url); remember to follow it with a die(); as the script continues to run even though the location has changed or avoid using it all together where possible.
Just declaring a global variable without using it in a function slows things down. PHP checks If it exists or now.
Not everything has to be OOP, often it is just overhead, each method and object call consumes a lot of memory.
Make use of the countless predefined functions of PHP, don’t attempt to build your own as the native ones will be far quicker; if you have very time and resource consuming functions, consider writing them as C extensions or modules.
Profile your code. A profiler shows you, which parts of your code consumes how many time. The Xdebug debugger already contains a profiler. Profiling shows you the bottlenecks in overview

Yahoo mail moving out of Beta

2011-05-25T03:42:00.000-07:00

Today Yahoo! announced that Yahoo! Mail will move out of beta and become generally available for millions of users in the coming weeks. With this latest version of Yahoo! Mail (available in multiple markets and multiple languages), Yahoo! offers a faster, safer, easier and constantly connected experience across all devices that keep the conversations going — anytime, anywhere.

Faster : Yahoo! put an emphasis on improving performance and delivered an experience that is at least 2x faster than previous versions. Whether you are on DSL, cable or dial-up, you’ll notice a dramatically faster Yahoo! Mail.

Safer : Yahoo! upgraded our SpamGuard system and Mail Anti-Phishing Platform (YMAP) to reduce spam and phish-laced emails by an additional 60% -- that’s on top of the billions spam messages Yahoo! block each month.

Easier : Yahoo! introduced even easier ways to connect and to share, organize and store online conversations and media content. Yahoo! added the ability to quickly reply to your Facebook friends, view inline photos and videos to engage and delight users, deeper integration with Yahoo! Messenger to support multi-mode scenarios, and new Apps like YouSendIt and All My Purchases to extend our eco-system.

Constantly Connected : And Yahoo! has made sure that these are seamless experiences that travel with you – allowing people to engage with Yahoo! Mail on a PC, iPhone, Android or tablet device.

The end result is a personally relevant communications experience — one that drives deeper engagement with consumers, excites advertising partners, and allows the teams to deliver continued innovation rapidly.

Firefox Bookmark Keyword Hack

2011-05-09T22:54:00.000-07:00

Previously I specified few firefox hacks to ease your daily internet surfing. Here I'm trying to explain how to use Firefox Bookmark Keyword hack.

Firefox provides a nice feature to Bookmark a URL and opening that for different input provided. E.g. If you want to search "Barack Osama", you can simply type "yahoo Barack Osama", and it will directly give your the search results.

Lets do it step wise.

Open the desired URL e.g. http://search.yahoo.com/search?p=Barack+Osama
Bookmark the page
Go to Organise bookmarks (FF version < 4.0) or Show All Bookmarks (FF version >= 4.0)
Search for the book-marked page here e.g. ysearch
Expand the property of bookmark (below "tag")
Replace the search string "Barack Osama" with %s
Enter keyword using what you want to do the search e.g. "yahoo"
DONE!

Type e.g. "yahoo < your name > " and enjoy the search results.

Don't limit yourself to this, create more bookmarks. Like for my personal use, I've setup many bookmarks like:

Facebook name search "fb < name >" (http://www.facebook.com/search.php?type=users&q=%s),
Bugzilla search "bug < bug id >",
Yahoo search "yahoo < search string >",
Microsoft bing search "bing < search string >",
Google search "google < search string >".

Delicious has a new owner, AVOS - founder of YouTube

2011-04-27T23:36:00.000-07:00

Yahoo! is excited to announce that Delicious has been acquired by the founders of YouTube, Chad Hurley and Steve Chen. As creators of the largest online video platform, Hurley and Chen have firsthand expertise enabling millions of consumers to share their experiences with the world. Delicious will become part of their new Internet company, AVOS.

Reasons to let Yahoo! transfer your bookmarks

• Continue uninterrupted use of Delicious.

• Keep your Delicious account and all your bookmarks.

• Enjoy the same look and feel of Delicious today plus future product innovations.

What happens if you do not transfer your bookmarks

• Delicious in its current form will be available until approximately July 2011.

• After that, you will no longer be able to use your existing Delicious account and will not have

access to your existing bookmarks or account information.

About AVOS

AVOS is a new Internet company founded by Chad Hurley and Steve Chen who, in 2005, founded YouTube, the world’s largest online video platform. Before YouTube, Hurley and Chen were early employees at PayPal, a leading online payment service that is now part of eBay. Delicious will become a part of AVOS, based in San Mateo, California.

Learn more about moving your bookmarks.

Thank you for using Delicious. Yahoo! has appreciated having you with us, and we are pleased to be able to transfer Delicious to an incredible new owner -- you're in good hands.

IE9 Release Candidate (RC)

2011-02-10T21:08:00.000-08:00

I never liked IE personally to use, specially IE6 which gave so many heart attacks (headache precisely) to almost every web developer and I'm a victim too. But after listening so many feedback and research work, I'm keen to try the new IE9 RC, and I hope this become irrelevant

Few good points in terms of performance and standards, which I hope stands true are

Faster with real world sites
Faster script engine
Improved rest of the browser
Network cache Tuning
New Compiler optimization

Become a better developer

2011-02-04T01:21:00.000-08:00

Search for the term ‘better developer’ and you find nearly 61 million results. It seems like everybody has an opinion on how to become a better developer, even the bad developers will tell you how to be a better programmer. After reading many of these programming self-help articles on being a better developer I found that the core message was all the same! If I could boil down the advice of all these results into a succinct list of how to be the best developer we are left with the following…

Read Everything
Learn Fast
Practice What You Know
Try New Things
Strive for Simplicity
Write and Teach
Assume Nothing
Question Everything
It is Not Personal
Rinse and Repeat

There is no one Golden Rule for becoming a better developer. Instead of single rule or a unifying theory of software development we have a set of core beliefs and best practices.

Here is the insight from many other developers on how to be a better software developer. In reading their advice, think what is universally true for all developers. What can we learn from each other, no matter

the development platform or programming language we use?

Dropping key on huge MySQL table

2010-06-29T08:53:00.000-07:00

Table alteration is never a cheap task to do, specially when dealing with large tables containing hundreds of GB data. ALTER TABLE may be required to add/remove column or indexes. Easiest solution to run it on production is to take the server one by one out of rotation, alter table, put it back in and sync up the data in between with other servers.

However, If it can't be done the only solution adopted by normal users is to fire the ALTER TABLE on production ending in ages to finish it, resulting in website down.

If some key is need to be dropped with the condition of no writes, we have one alternate solution for the same, to make ALTER TABLE faster.

Say there is some huge test table containing lot of data:

CREATE TABLE `test` (

`rollno` INT UNSIGNED NOT NULL DEFAULT '0',

`name` varchar(100) DEFAULT NULL,

`score` MEDIUMINT UNSIGNED DEFAULT '0',

PRIMARY KEY (`id`),

UNIQUE KEY `name` (`name`)

) ENGINE=MyISAM;

Now If there is a requirement to drop unique key 'name', so create a new table say test_new:

CREATE TABLE `test_new` (

`rollno` INT UNSIGNED NOT NULL DEFAULT '0',

`name` varchar(100) DEFAULT NULL,

`score` MEDIUMINT UNSIGNED DEFAULT '0',

PRIMARY KEY (`id`)

) ENGINE=MyISAM;

Flush both tables with read lock:

mysql> FLUSH TABLES WITH READ LOCK;

Open another terminal. And go to the mysql/data/ directory. Do the following:

mysql/data/test $ mv test.frm test_old.frm; mv test_new.frm test.frm; mv test.MYI test_old.MYI; mv test_new.MYI test.MYI;

Table definitions are switched here. The table definition of test now doesn't contain unique key.

Now unlock the tables in the main window. And run repair tables to remove any issues.

mysql> UNLOCK TABLES;

mysql> REPAIR TABLES test;

+---------------+--------+----------+-------------------------------------------+

| Table         | Op     | Msg_type | Msg_text                                  |

+---------------+--------+----------+-------------------------------------------+

| test.testhack | repair | warning  | Number of rows changed from 0 to 20000000 |

| test.testhack | repair | status   | OK                                        |

+---------------+--------+----------+-------------------------------------------+

The repair table rebuilds the indexes. It is faster since it skips the use of key_cache for rebuilding the index (which is used in a normal alter table scenario).

Note, don't forget to take the backup in the advance in case if anything goes wrong.

What is the need?
Sometimes it is needed that you want to execute some scripts automatically at your page using some client side language (e.g. Javascript). Some good examples are like Mob Wars, Mafia wars or FarmVille where attacks etc are automatically done with certain defined rules . Another example may be automatically retrieving data from other sites to make two sites more interconnected.

What is Greasemonkey?
"Greasemonkey is a Firefox extension that allows you to write scripts that alter the web pages you visit." Using Greasemonkey extension many script can be executed as a hack to the Firefox to make your work smoother.

How to install?
Download from http://www.greasespot.net/, install and restart the browser (Firefox). Scripts can be installed then after. It name must end in .user.js

Monster acquired Yahoo! Hotjobs for $225 million

2010-02-03T21:10:00.000-08:00

After Yahoo! search, Yahoo! Hotjobs is also sold. Monster, one of the best known in online employment websites, announced about the acquisition of Yahoo! Hotjobs for $225 million. These two giants now have a 3 year traffic deal as part of the acquisition.In a statement "The sale of Yahoo HotJobs to Monster, and the three-year traffic agreement with Monster, represent an attractive opportunity for Yahoo. The transaction will provide Yahoo with an upfront cash purchase price of $225 million; the ability to focus more on its core business and delivering exceptional experiences to its users, partners and advertisers; and the opportunity to drive longer-term value through the traffic agreement by allowing Yahoo to continue to generate revenue from the online recruiting space while continuing to provide users with valued online career and recruiting services."
Monster is one of the largest in terms of traffic and user world wide, while Yahoo! has brand associated with its product. Yahoo seems to be selling some of its less strategic assets, as last month Yahoo! also sold Zimbra to VMWare, though still has some of the Zimbra technology.

HipHop for PHP project from Facebook

2010-02-03T01:07:00.000-08:00

Today, Facebook shared one of its cool project - HipHop for PHP. Over 90 percent of Facebook servers are now using HipHop as the project opens to the community, promising better performance and scalability.

What is the use?
HipHop can reduce the CPU usage at the server even by 50% depending on the page executing PHP code. Reducing the overhead this way, it can help in scaling complex PHP websites. As per Facebook latest news, HipHop has shown incredible results for Facebook.

How does It optimize?
HipHop doesn't work like a compiler technically, instead HipHop programmatically transforms your PHP source code into highly optimized C++ and then uses g++ to compile it. HipHop executes the source code in a semantically equivalent manner and sacrifices some rarely used features — such as eval() — in exchange for improved performance. HipHop includes a code transformer, a reimplementation of PHP's runtime system, and a rewrite of many common PHP Extensions to take advantage of these performance optimizations.

It's not complete yet, but beta software can be tried before trying it out. I need to still try it out.

Oracle Finalizes Acquisition of Sun

2010-01-28T22:07:00.000-08:00

Finally much awaited deal of sun Acquisition by Oracle is done. As per the latest newsletter from sun:

"We are pleased to announce that Oracle has completed its acquisition of Sun Microsystems and Sun is now a wholly owned subsidiary of Oracle. With this news, we want to reiterate our commitment to deliver complete, open and integrated systems that help our customers improve the performance, reliability and security of their IT infrastructure. We would also like to thank the many customers that have supported us throughout the acquisition process.

There is no doubt that this combination transforms the IT industry. With the addition of servers, storage, SPARC processors, the Solaris operating system, Java, and the MySQL database to Oracle’s portfolio of database, middleware, and business and industry applications, we plan to engineer and deliver open and integrated systems - from applications to disk - where all the pieces fit and work together out of the box.

Performance levels will be unmatched. Oracle’s software already runs faster on Sun SPARC/Solaris than on any other server or operating system. With Sun as a part of Oracle, each layer of the stack will be engineered to further improve performance, reliability and manageability so that IT will be more predictable, more supportable, and more secure. Customers will benefit as their system performance goes up and their system integration and management costs go down.

In addition, our open standards-based technology will give customers choice. Customers can purchase our fully integrated systems, or easily integrate our best-of-breed technologies with their existing environments. Our open technology also enables customers to take full advantage of third party innovations. Oracle also plans to extend its partner specialization program to include Sun technologies to better enable partners to deliver differentiated and value-added solutions to customers.

As always, our primary goal is 100% customer satisfaction. We are dedicated to delivering without interruption the quality of support and service that you have come to expect from Oracle and Sun, and more. Oracle plans to enhance Sun customer support by improving support access, offering better interoperability support between Oracle and Sun products and delivering services in more local languages. Support procedures for your existing Sun and Oracle products are unchanged, so for now you should continue to use the same channels you’ve been using. Customers can continue to purchase products from Sun in the same way they did prior to the acquisition. We will communicate any changes to this through regular channels.

We are very excited about this combination and look forward to delivering to you increased innovation through accelerated investment in Sun’s hardware and software technologies such as SPARC, Solaris, Java, and MySQL. If you weren’t able to join the live event on January 27 where we, along with Larry Ellison and other executives from Oracle and Sun outlined how this powerful combination will transform the IT industry, you are welcome to view the replay that can be accessed at oracle.com/sun.

Sincerely,

Firefox hacks to make browsing easy

2010-01-23T05:32:00.000-08:00

Undoubtedly, Firefox is the best browser available in the market. Virtually there is no limit of customization you can do with Firefox. Most of these comes as extensions (add-ons).
However, settings can also be customized easily by accessing convenient location using Firefox's "about:config" hack, which can be opened by typing it into the address bar. Steps to change settings can be followed as:

Type "about:config" in the address bar, and press enter
Search for the setting in the "Filter" bar within that
If desired search result found, double click to change the value, which can be integer, Boolean or string type
In case a setting doesn’t show up in the search, just right-click and select New to create it.
Restart Firefox

By following the above steps, different customizations can be done. I'll list a few here which may be useful for you as well.

1. Stop sites to blink the Text : Some websites have blinking text which irritates a lot. It can be stopped as

In Filter search, type: "browser.blink_allowed"
Set its the value as "false"

2. Open search result in new tab : Search has become the integral part of our net surfing, and while using Firefox, I quickly hit "Ctrl + k" or "Command + k" (mac) to type the keywords to get the results. However, either it will over-write the existing page or I need to open new tab first, which means extra key strokes. The setting to open the search results in new tab can be done as

In the Filter search, type: "browser.search.openintab"
Set its value as "true"

3. RAM (Memory) optimization when Firefox is minimized (Windows only) : RAM is a precious commodity. All the applications carry out their processing in the RAM. Many applications in some operating systems, returns unused RAM when they are minimized. The problem with Firefox arises in the way it handles RAM - Not releasing it when minimized. It can be handled using config.trim_on_minimize setting. Please note that, it (Windows only) does not reduce the amount of memory used, it just swaps memory from RAM to disk.

Create new Boolean variable "New -> Boolean" by doing right click
Name it as "config.trim_on_minimize" and set the value as "true"

4. Maximum amount of pages to be stored in memory (more) Variable browser.sessionhistory.max_total_viewers can be set to some positive number in about:config to limit the amount of pages to be stored in the memory. Default is -1, which means it automatically determines the maximum number of pages. Users not facing any memory problem may set -1. To change it

In the Filter search, type: "browser.sessionhistory.max_total_viewers"
Double click, and change value to some positive number (number of pages allowed to be stored in memory)

5. Use Firefox Bookmark Keyword

Favicon Optimization - Some facts

2009-07-07T22:19:00.000-07:00

Every time a page a requested, favicon is also downloaded if present at the server. Though favicon download doesn't affect you page response time directly, but it share the bandwidth. So better to keep favicon small (preferably less than 1 KB) & cacheable.
Favicon can be used in two ways:

Keeping the favicon.ico file in the server root directory
favicon.ico using link attribute in the header of the HTML

I consider second approach better for the following reasons

can be cached with the proper expiry header and can be served from CDN.
E.g. <link rel="shortcut icon" href="http://in.yahoo.com/favicon.ico" type="image/x-icon" />

Please note that, If favicon is changed, It name cann't be changed to clear the cache, so choose the expiry time wisely.

However there are something more to know about the second approach:

IE loads favicon before lazy-loaded components.
It increases the load on your application server.
Favicon loaded with a <link> are loaded early in the FF waterfall

Thunderbird

2009-07-04T10:03:00.000-07:00

After using Evolution & Outlook, I move to Thunderbird. Definitely it is the best mail client I ever used. However, I tried some of it useful configurable options.

A. Modifying Thunderbird's Reply Header [1] : By default while replying, you may want to include the date (timestamp). Go to Edit / Tools => Preferences / Options => Advanced => Config Editor => search for "mailnews.reply_header_type" and set it 3.

[1] http://panicbook.blogspot.com/2006/10/modifying-thunderbirds-reply-header.html

B. Lightning at Thunderbird 3.0
1. Go to 'Tools -> Add-ons'
2. Click 'Get Add-ons' tab
3. Search for "Lightning" here or at https://addons.mozilla.org/en-US/thunderbird/
4. The results will show "Lightning Nightly Updater (Unofficial)"
5. Install it
6. Restart Thunderbird
7. Go to 'Help -> Check for Latest Lightning Nightly Builds...'
8. Pop-up will show the latest Nightly Build of Lightning which is available
9. Click on Install
10. Restart Thunderbird
