This is basically to keep tests in place for MySQL order bys ... which I know make absolutely no sense, but if there's a requirement and someone changes something I like a test to break to tell them I didn't put the order by in there for nothing.

I never knew you could have a horrible Christmas day, I just never knew.

So yes, it's been an injuringly long day, and I'm this close to falling off and falling asleep but I promised myself I'd blog today, so here we go.

One, it's insanely hilarious how I promise myself I'll blog about inane shit like today, and not blog about the stuff I'm doing technology wise, must make note to blog about:
1. Signed Javascript Apps.
2. Deploying them.
3. Making a Rails plugin.

Two, I cannot dance. I'm just not cut out like that. No I'm serious man, I'm sure I'm defective in that way, and my sweet sister has asked me to dance at her wedding on a grand total of four songs. I swear, I was going to fall down and die when I heard that. I mean, yeah four whiskeys later I'm doing all kinds of things on the dance floor, but you're talking about serious choreographer stuff here. I know I'm part of my family and all ... but ugh man, I suck at dancing. The problem is we Sindhis take out wedding dances very very seriously. I remember a time when I was a kid, and dancing used to be fun and I used to be able to do hand stands and be funny and that was acceptable. Now ... well let's not go into that. I know two songs I'll be dancing on so far. Bring It On and Partner. Wheee.

Three, New Years' I will be in Bombay partying it up with friends, so whopeee!!

Four, Christmas ... I did fairly nothing. I've been adding a custom search to the lyrics website and it's not working out well, so I need to work on that a tonne.

Five, I've been playing Devil May Cry 3. And it is damn damn damn kickass.

I think I'll sleep now. I want tomorrow to be a nice day. A merry and nice day.

Gift List ... Final

Posted In: . By Sid

This time, ordered according to priority.

1. NYC vacation: No questions asked. This is and always will be number one.

2. MacBook Pro: I have decided I don't want to go to jail before the age of 30, hence killing Mr. Dude for his black MacBook Pro is not something I want to do.

3. iTouch: It's just so damn pretty. And plus music addiction is so my thang.

4. Books: Somewhat last on the list, because well ... I'm smart already, reading is for people who don't have MacBooks.

5. Uber - God like power: This I know I won't get. But what the hey. I want stuff like teleportation (most important), ability to read people's minds (very cool), super batting power (I'm Indian what to tell you), carrom skills (I just really suck at carrom)

So yes, beer makes me want gifts. You didn't know that did you?

 

Ruby StringIO and clone

Posted In: , , . By Sid


>> a = StringIO.new("abcd")
=> #<StringIO:0xb6e1b354>
>> b = a
=> #<StringIO:0xb6e1b354>
>> b.read
=> "abcd"
>> b = a
=> #<StringIO:0xb6e1b354>
>> b.read
=> ""


Notice the hash signature for b is the same as the hash signature for a. Which is why even though you re-assign it to point to a it's already read the contents of the StringIO you created and hence nils out.

Now see this.


>> a = StringIO.new("abcd")
=> #<StringIO:0xb70570a0>
>> b = a.clone
=> #<StringIO:0xb7055994>
>> b.read
=> "abcd"
>> b = a.clone
=> #<StringIO:0xb7053464>
>> b.read
=> ""


The first time you clone a and point it to b, it creates the hash signature as "#<StringIO:0xb6d968ac>" and the second time you clone it it creates a different hash signature "#<StringIO:0xb7053464>". Hence, multiple clone calls actually still point to different memory space, but it's still the same variable?

Now see this.

>> a = StringIO.new("abcd")
=> #<StringIO:0xb7042240>
>> b = a.clone
=> #<StringIO:0xb7040bfc>
>> b.read
=> "abcd"
>> b.rewind
=> 0
>> b = a.clone
=> #<StringIO:0xb703d1dc>
>> b.read
=> "abcd"
>> b
=> #<StringIO:0xb703d1dc>


Apparently when I clone an object, it still retains the property that StringIO has been read. Which behaves uniquely for StringIO considering the read pointer concept. But yes, somethings amiss.

Are you smart enough?

Posted In: , . By Sid

Would you put lines on your resume that essentially say:

"(bullet point) I am smart"
"(bullet point) I am awesome"

The premise initially is you would only add a line that says you're smart if you think people wouldn't think that when they read your resume or met you.

But, if that's common sense, then are you smart enough to realize that smart people don't put lines on their resume that say they're smart, for people who don't have enough time to assess that. So, are you smart enough to say you're smart, when all the smart people are really scared of looking like they're trying to hard.

The real question is should I work, or should I work?

I should work.

Who put kryptonite in my tea?

Some days you wake up feeling like the man of steel. You feel like you take on a hail of bullets and have a Harry Potter to show for it.

Some days someone puts kryptonite in your tea. And you just want to kill something.

You know how some people just never have any luck ordering pizza. You know me then. I've never had a good experience ordering a pizza home, like ever! I don't know why I still do it. I just don't. Every single time I order a pizza it comes in late. So yeah, I can deal with it you know, I'm not exactly the kind of guy that likes to eradicate a people.

Pizza guys are great though, they do this thing with the "I'll give you a 50% off on your next purchase with us" which is so awesome!

Because well you get 50% percent off AND you have to be darft enough to order pizza home from the same idiots who got your pizza late to begin with. I never really followed up with the discount so I don't know if it would happen, but I'm willing to bet they would have got that late too.

What really gets to you though is when you throw your hands up and say:

"Dude, the pizza place is 10 minutes away from the office there really is no excuse for an hour and a half delay. I don't want a discount man, just do something about how you take your orders."

Now, somehow in some weird pigmy ass interpretation Mr. Pizza guy (nameless) interprets that as a "Please say something about discount offers that will insult me."

"Sir, I am prepared to offer you a 15% discount now .... or 50% off on your next purchase."

Honestly man, whoever came up with that kind of an offer should be shot. But more honestly, the guy who took either side of that offer should be mutilated.

Don't ever do that to anyone. Ever. It's just very very hollow. To incite that someone is being greedy is to err. But to incite that someone is being greedy and to make them choose between two options that both have "Sell your soul to me, because I deliver pizza late and throw money at people who complain" is just shit. Have some balls. Take some responsibility, it's okay to go hungry for one night but the satisfaction of telling the pizza guy to shove it makes my day anyday.

And one more thing, don't give in to the rickshawallahs ... ever! Stand your bloody ground, if you belong to Pune, make it your home. Don't let some asshole take it away from you because you're too lazy to walk a few minutes. Make the effort, it's always worth it.

Useful Unix Tricks I Stole

Posted In: , . By Sid

Here's some useful Unix tricks I use/should be using at work everyday.

Useful Unix Tricks

Useful Unix Tricks Part 2

Big props to Paul Gross

 

If you have code that uses DateTime.now you ask yourself "How's my test supposed to pass?" and your pair says "I'd peg it at 1 out of ten times" and if your pair is Rohan Kini you know you have a way out.

Let's set it up right. I have this object:


class User

def initialize
@time_of_birth = DateTime.now
@name = "The dude"
end

def take_over_the_world
p "#{self.name} is taking over the world"
end

end


The tests for which look like


def test_if_use_is_born_with_right_defaults
the_dude = User.new
assert_equal the_dude.time_of_birth, DateTime.now
assert_equal the_dude.name, "The dude"
end


Now obviously a few milliseconds might have past since the execution of User.new so odds are your test will fail even though they should pass.

Here's how you change things around a bit.

In your user class you need to abstract the DateTime.now bit, so you can override things in your test


class User

def date
DateTime.now
end

def initialize
@time_of_birth = date
@name = "The dude"
end

def take_over_the_world
p "#{self.name} is taking over the world"
end

end


And in your test override the new date method you created.

NOW = DateTime.now

class << User

def date
NOW
end

end

def test_if_use_is_born_with_right_defaults
the_dude = User.new # Will use now because you've overridden User::date in the context of this test
assert_equal the_dude.time_of_birth, NOW
assert_equal the_dude.name, "The dude"
end

 

IntelliJ EAP/M2 on Ubuntu

Posted In: , , . By Sid

If your using the Ruby plugin with Intellij which by the way is way feckin' awesome your should be suffering some performance issues. Intellij eats up about 300 to 400 megs easily and it's really deathly slow. Especially if you try running your tests out of IntelliJ.

Here's something to speed things up a bit. Open up #{idea_directory}/bin/idea.vmoptions and make it look like this:


-Xms300m
-Xmx512m
-XX:MaxPermSize=99m
-ea
-XX:+UseConcMarkSweepGC
-server


The first line specifies that idea should load up with 300 megs, this is good because it ensures idea doesn't go "allocate allocate allocate" because it has sufficient memory ot begin with.

The second line specifies max memory. You can up this number. My dell has only one gig hence I keep it at 500 megs.

The UseConcMarkSweep is way cool, because it's an alternate garbage collection algorithm which the JVM uses and is way efficient if your running a dual core.

The server argument to the JVM is good for long running processes because the JVM optimises it that way.

Thanks to Chris Stevenson for this life saver.

 

The return of the warlord

I know I haven’t posted in forever. But hey, I was busy :P

I’ve spent the past six weeks in Bangalore attending ThoughtWorks University which is their training programming for freshers like me.

I’ve learned loads of technology, not to mention agile methodologies. We got to spend a good amount of time with the Chairman of the company, who is by far the nicest boss I’ve met aside from my brother and previous Project Manager of course.

I’m at home now.

I’m also reading this book called "The curious incident of the dog in the night-time" It’s great!

 

You have a textarea and you're rendering the text you get from it on a page.

Textarea Input:

This is on the first line.

This is on the second line.

This is on the third.

Browser Output:

Now that sucks.

Firefox print preview eyuck!!

I mean, it's actually pretty nice, it's us who were screwing up but c'mon everyone keeps saying all these nice things about firefox it's about time someone played Devil's advocate!

Problem: Firefox's print preview ate up pages 197-200 pages of a 300 page print preview and for some reason rendered the rest as un-tabulated HTML even though in the HTML source the HTML was perfectly formatted, other browsers Safara, Opera (notice me not saying IE) displayed things perfectly.

The shakedown:
1. We were inserting page break's programmatically using CSSs'


<div style = "page-break-after: always;"></div>


2. Somewhere in the code there was a float: left and float: right trying to create a div that exists side by side on the same page like I do with my sweet brother. Unfortunately, and I can't stress this enough only one float can exist in this town bubba! Use a float and a margin if you like, it's good CSS, I learnt it from the O'Reilly book.

leftElement {
float: left;
}

rightElement {
margin-left: some_number em;
}

PS: Use "em" please ... don't use "px" be more in-support-of-resizing-fonts/usable/awesome. em is based on the font-size of the element and pixels are just poison if you resize.
Also, as the paranoid boy in me keeps insisting use a div with a style that clears everything to make sure you have no float's affecting something else's behaviour.

<div style = "clear: both;"></div>


3. Somehow the extra float: right killed the page-breaks we tried to insert ... how and why I cannot tell ... and will probably never be able to find out, but to gain something from this, try using the Firebug extension, it is seriously the shiznit of the time. So if your page-breaks aren't working as expected or anything isn't for that matter give it a shot, good stuff!

Usually on a Ubuntu install you install rails via


sudo gem install rails


But, sometimes this leaves the symlinks in the vendor/plugins folder broken. You fix it as follows


sudo apt-get install rails


Who'd have thought you need to both eh? Well, the new Rails install guide for Ubuntu Fesity fawn tells you to do so, but not why.

Anywho, if you need by any chance to downgrade a version like I did. Apparently rake tasks that use ActiveRecord objects don't work quite well on Rails - 1.2.2 so I had to go down to Rails - 1.6.6


sudo gem install rails -v1.6.6


Go to http://packages.ubuntu.com and get the specific version of Rails from there.

EDIT:

The reason for this is, by default your server will first look for Rails inside your MY_APP/vendor folder, and since those symlinks are broken will complain since an install using gem doesn't put Rails inside the /vendor folder, it only creates symlinks.

A fix is just to delete what's in the MY_APP/vendor folder.

Here's the shakedown, both essentially do the same thing, they take what's in the ActiveRecord, use the Model and take the information back to the database but there's one very important difference between the two.

Save incorporates all your filters (validates_uniqueness_of etc.) but update does not. So you say, oh pishaw big bloody deal! Well, I'll why this really is a big deal ...

Say you have a Model and a filter


my_models (
id int,
number int,
name varchar(200),
status boolean
)

validates_uniqueness_of :number, :scope=>:status


What this does is, is asserts the uniqueness of the combination of 'number' and 'status'. Yeah, yeah Mr. Fan, Manowar get on with it.

So you have a delete method which goes:


@model=MyModel.find(id)
@model.status=0
@model.save


Now, we assume that there is another entry into the my_models table which has the same 'number' as the entry we're trying to update but a different 'status' say false. And on deletion we're setting this 'status' attribute to false. The point to note is that the save method will fail on the validate_uniqueness_of callback filter, but it will fail silently, and that my men is what introduces a bug.

Use update in scenarios like that, it works out well.

So, you know I broke it again. But I guess I learnt some jazzy stuff about the configs. If you're using Rails and you keep getting these errors


Can't connect to local MySQL server through socket '/tmp/mysql.sock'(111)
Can't connect to local MySQL server through socket '/tmp/mysql.sock'(13)
Can't connect to local MySQL server through socket '/tmp/mysql.sock'(2)


You need to be editing your /etc/mysql/my.cnf as well as your /etc/mysql/debian.cnf and make them all point to either /tmp/mysql.sock or /var/run/mysqld/mysqld.sock whichever you feel works better with your Rails app.

A simple sudo /etc/init.d/mysql restart should work, if it doesn't you're a special special person with special special needs.

MySQL purge configuration

So MySQL is no fun, if you can't fool around with it. Fool around with it enough, and you'll have to just get rid of /etc/mysql/* and oddly enough apt-get doesn't replace those files if you do a clean install.

Ergo:


sudo apt-get remove --purge mysql-server
and

Then when installing Rubygems I used some stow method, which I would not recommend because this method doesn't install the gems you're installing into the current path. Which is oh so sucky. Because then to add everything to your path, you need to keep editing the .profile file.

All in all, Monday suck my balls, because everything now works. HooHaa.

The Guild - Pune Barcamp 3

Posted In: , . By Sid


This Saturday I was at the Pune Barcamp 3 and as usual it didn't fail to deliver. As a technology conference admittedly the Barcamps I've attended so far have been centered around the startup experience and mainly web technologies, but given that the people in these two spheres heavily rely on networking it's not surprising :)

There were some really interesting seminars that deserve a mention.

1. Ketan's seminar on how Eclipse is not just an IDE but can be used a plugin development IDE to develop tools that can do a whole diverse range of stuff.

2. Aditya Thatte's presentation on the upcoming Miscrosoft Silverlight. I think this one deserves a special mention for the quality of the presentation's delivery and response.

3. Freeman's presentation on open source education initiatives.

4. The presentation on how setting up base in the USA, UK and Singapore helps in terms of tax cuts. This one again deserves a special mention for the presentation as well as the content, quite an eye-opener.

Freeman said something very interesting on how the Barcamp community is almost a guild of techies who take care of each other. Cheers to that!

I'm struggling with all these versions man. Everytime I install something using apt-get or even with IntelliJ or even with IntelliJ's Ruby plugin I end up with a version that is way below par. Man, why isn't everything just ... consistent!

And then there's the fact that when the install works, it's not like in the demo. Just not like in the demo.

Skype + 64-bit Ubuntu = :(

Posted In: , . By Sid

Skype doesn't have a release for 64-bit Ubuntu distributions. I'm running Ubuntu Feisty fawn that's Ubuntu 7.04. The .deb from the Skype for Linux download page doesn't work on a 64-bit architecture.

Here's some documentation on how to work around it.

The fix didn't work for me though :( All I got after installing was a "/usr/sbin/skype doesn't exist"

 

Okay, so I removed my brand new Kubuntu install and went the old Creepy Happy People way.


Disclaimer: No matter what I say, I frikin' love Ubuntu.

So you ask me why I uninstalled Kubuntu? Because I'm now running the 64-bit Ubuntu! So you ask me why again ... two reasons:

1. The bum on this side of the screen didn't know that the Dell Latitude D620 runs an Intel Core Duo T2400 1.83GHz processor which can calculate the value of PI upto 2 million digits in 1m 21s has a 64-bit architecture! Well DUH!

2. I'm like that.

So yay for old times sake, one more Creepy Happy People pic.

So you ask what's so interesting about today? It seems like just another day, another Wednesday, another 4th of another July. Well, you would be damn wrong, oh so damn wrong!

Today is my first day at work at the ThougthWorks Pune office. I sit here on the laptop they gave me, a Dell latititude, worried sick about someone catching me blogging. Everyone around me is arguing and working, and a lot of people seem to be eating banana chips. I love those things!!!

I'm not working right now, because
1. I'm like that.
2. I'm actually going to be working on a Ruby project (dance dance dance) but the problem is the developer I'm supposed to pair with is not in town. He comes back on Monday ... till he gets back I'm a bum with a mission, setting everything up.

All I get to do is sit here and blog my ass raw. Sigh, all the good things in life elude me till I actually go out and get myself a job.

I will be posting some pictures from my first day here, so watch this space fo the shizzle mah main man!

Oh yeah did I forget to mention how awesome this place is? I mean seriously ... I can work in shorts. Pishaw to all you others who feel bad, go tear of your pants. GO!

[Music: Ivar Peersen - Lyrics: Ivar Peersen]
[* = excerpt from Norwegian author Aksel Sandemose, book Vi pynter oss med horn]
Dei for ifra nord
Mot ei anna tid
Bak låg brende ord
Framfor dei ei ny strid
Dei såg såg stormar i det fjerne
Men haldt fram og beint
Inn mot jordas kjerne
Frå tidleg mot seint
I see a darkness overwhelming
I see that there is no light for me
I don't care if it leaves me blind
I don't care if I'm left behind
I see a white horse's head
I see it's dead stare fixed at me
I do not fear its eyes
Curse myself, return it twice
I see walls to high to climb
I see nothing on the other side
I should have roamed another space
I should have been another place
*Dei daue gror opp av havet og ropar så sårt mot land.
Dei ropar bak alle skuter, som kavar seg tungt forbi
I am among ghosts when I should rest
I cannot tell the worlds apart
I do not heed the words they say
There is no dream of another day
I hear a silence, deafening
Drowning the deserts, that is my destiny
I no longer wish to see
The threads they've spun for me.
Dei for ifra nord
Mot ei anna tid
Bak låg brende ord
Framfor dei ei ny strid
Dei såg såg stormar i det fjerne
Men haldt fram og beint
Inn mot jordas kjerne
Frå tidleg mot seint


The norse verse is translated as:
"We put on horns."

They came from north
towards another time (/era/reign).
Behind lay a burning word
ahead lay yet another toil (/feud/battle)
They saw storms in the distance
but persisted boldly and brave
into the earths core
from early to late (meaning: restlessly).

The two extra lines are translated as:
The dead rise from the water and wail scornedly to shore
Calling from behind all ships that ladenly crawls by.

Yeah, I like the Norse version better. Sounds like a kickass sailor's song. Thanks to *I will keep him anonymous* Norwegian dude form Orkut who knows Mixed Martial arts!

You should see the segment from the Metal, A Headbanger's Journey movie where the song plays. Beautiful stuff.

 

Being a victim of malware spread via USB, I felt this post is quite justified. Have you had the experience wherein you plugged in your USB drive and double-clicked on it and nothing happened ... and everytime from then on that you've tried to eject a drive didn't work. Well, people you've infected your drives and computers for long enough.

Here's how to deal with it:

1] For your drive, plug it into a Linux PC and delete the autorun.inf file or do it using a Windows PC without double-clicking on the drive icon. By not double clicking on the drive icon your basically not running the code in the autorun.inf file.

2] For your PC, a format and re-install is the best solution, but in case you're not infected and looking for a solution, here's what to do via Thushan Fernando's blog:
1. Start > Run, type in 'gpedit.msc' without the quotes, this will show you the Group Policy Editor.
2. Goto 'Computer Configuration' > 'Administrative Templates' > 'System' and select 'Turn Off Autoplay'
3. When the properties for the policy pops up, check 'Enable' and select 'All Drives' and hit OK.

Cheers and stay safe!

There are three kinds of people in this world. Those that believe the ends justify the means, those that don't and then there's the types who could care less about the end.

It's all about the means.

Do something for the heck of doing it, not for the end result. It's quite liberating. More fun than liberating, really.

Hence,

my luck = (((whole world's bad luck) / (no. of people in this world)) * (no. of people who watch My Name Is Earl)) cubed

And since everyone in this world knows and watches My Name Is Earl.

Ubuntu is the man

Posted In: . By Sid

Okay, I remember I did this post when I was really frustrated with the whole Ubuntu scenario, but I gotta say ... I've really grown to love this OS. And here's why:

1] It takes me exactly half an hour to do a Ubuntu re-install as opposed to a crappy one or two hour windows install. Although reinstalling stuff on Ubuntu involves a lot of downloading, I guess one way around is to download all the packages you need and use an install CD. Will post about that.

2] It's FREE! I mean, I don't have to worry about ripping stuff, and breaking the OS. Btw, that's how I broke my last windows install, WMP 11 was just too tempting.

3] Breaking Ubuntu happens, but not as often and unexpectedly as breaking Windows used to happen. Plus, with Ubuntu mostly everything is transparent so the fixes are about 50% obvious, the times that they're not obvious the forums rule!

4] I agree Ubuntu doesn't look as sophisticated and slick as Windows does, but hey that's part of the charm.

5] Hardware support can be an issue, but hey if you're smart enough to try installing some esoteric device you're smart enough to make it work.

I would suggest switching to anyone who'se using a ripped copy of Windows ... it's a good feeling to know you're not breaking any laws :D

 

Update

Posted In: . By Sid

Whew!! A lot has happened over the past few weeks, and a lot really means a lot.

One, Rohit and I won first prize at the intechxication intra project competition and we won the prize for the best mobile computing project at the inter college competition... which is odd because ours really has no mobile computing as such, I think the college had trouble classifying our project.
We would or could have won the inter all the way too, but our second judge was a real asshole, he never even saw our demonstration :( Throughout our presentation he just kept nodding ... I was so enthusiastic about it, total turn off, but hey I put my best foot forward and at the end of the day, that's all that matters. Plus, we won 5k and we're entering another competition hopefully :)

Two, my project is finally over and done. It works great, exactly as expected which makes me immensely happy. This also renders me aimless in life, which is fun and sad at the same time. Odd feeling really, not having to think about it, but I guess there's a time and place for everything.

Three, I am so not good with details. From now on, I'm going to be that person who runs around with a pad and writes down things, like e-mail addresses especially.

Four, I had some stuff in mind to blog about as regarding technology ... but it's all just completely slipped out of my mind. The past three weeks have been really amazing that way, everything working and all. I guess I'll blog it out as it comes to me.

Five, I had an excellent time with the folks at ThoughtWorks at their family day!! I learned I am very very very BAD at bowling, and no this is not good bad, but bad bad. My second try I managed to smack the ball at the ceiling, yes ceiling. Temporarily, I think it would do me some good to put my bowling career on hold. That and I sprained my right wrist, very sad news I know, painful though. I had to draw up the charts for my project stall with that wrist. Feels better now, and I'm actually thinking of giving the whole bowling thing another go. :D

BookEazy

Posted In: , . By Sid

The post that follows is the honest truth and bear in mind, I know it sounds to good to be true :) But it isn't ... it's just awesome.

Every Friday the movies in Pune change in the theatres. Last Friday, the movie change was to 300. Now if you've been on the internet or been watching TV you would be affected by this buzz 110% The 300 is a gory movie about an epic David Vs. Goliath battle.

My point though is how I went for the movie. Now you must understand E-Square is one of the more popular multiplexes in town and going for a Friday night movie at 9:30 without prior bookings is unheard of!

But I did it.

Yes sir. I sadly even showed up five minutes late :) But my tickets were still there for me.

All thanks to the guys at BookEazy. BookEazy is a movie ticket booking service which allows you to book tickets online and pay for them on arrival at the theatre. You don't have to come early/wait in line ... none of that jazz, just book your tickets and enjoy your BookEazy movies as one of my friend eloquently puts it.

The service is awesome, in the sense you don't have to worry about advance bookings at all, just book online, as soon as you book tickets you get a confirmation SMS which you can show to one of BookEazy's special counters at the theatre of choice and get your tickets immediately :)
You can even check out show times for your favourite movies for free on the website.

Plus, you even get to know your seat layout and stuff, online :)



I couldn't emphasize this enough, how convenient this service has been. Trust me, how much ever I say it, it won't be enough. You have to go through it to believe it. I got my tickets at the theatre in under 10 seconds.

Frequent moviegoer or not, the convenience cannot be denied.

Rails and Scaling

Posted In: , , . By Sid

Okay, so I love Rails. But, Rails has an issue with scaling. A fresh install of Rails for instance comes with sessions implemented in the file system. That's all well and good for a development box, the issue arises when you're serving more than a small number of clients.

Serializing data shared by processes in a file is doable. You can use identity stamps and all that jazz, but it slows things down I imagine.

So the alternative is using my favourite ... tables! Or in our case ActiveRecord, the layer of ORDBMS on top of your database.

It's quite simple. All you need to do is find this line in your config/environment.rb and uncomment it.





After this is done, set up the tables by running.


rake db:sessions:create
rake db:migrate

Toggle the code!

Update:

Alrightie then, first rule of entrepreneurship, don't believe in technology (hype). Hmmm, so the ActiveRecord method of storing sessions that Rails ships with is not so good.

Rails is excellent to say the least in the development environment, but production on the other hand involves a lot of fun.

Right now, I'm going to settle for a 60GB hard-drive 1GB memory 15 inch wide screen Xubuntu production box.

Also, for production sake, the alternative's to the ActiveRecord method of storing sessions; you could use SQLSessionStore for sessions, or better still the better performing memcached.

I'm reading this article on how to deploy Rails on a mongrel cluster and Apache.

 

Toggle Code View.

Posted In: , . By Sid

I spanked out some Javascript, very useful albeit simple. It just toggle my code windows, some of them look pretty ugly. Especially the one associated with my Xubuntu-DKU2 post.

So this is what it looks like:


function toggleVisibility(obj){
if (obj.style.display=="none")
obj.style.display="block";
else obj.style.display="none";
}

Toggle this code!

Add that function to your template and this to your blog entry after the code div.

<a href = "#" onclick="toggleVisibility(getElementById('your_div_element_id'))">Toggle the code!</a>

Toggle this code!

Don't forget you're div element's id should match the id in the link.

Xubuntu woes.

Posted In: . By Sid

So, I'm having a problem with Xubuntu. The only problem ... really, rest everything is dandy.



Whenever I use Synaptic to upgrade my Firefox install or try to install some GUI like the MySQL Query Browser Synaptic tries to remove the following packages:



1. xwindow-system-core

2. xserver-xorg

3. xubuntu-desktop



When I remove these packages and restart my PC the XCFE GUI is gone, I tried restoring the packages using the shell apt-get but it didn't work. I had to re-install Xubuntu.



Someone help! I've posted this thread on the UbuntuForums



EDIT:

Problem Solved!!



Turns out, my Synaptic sources.list was jinxed. I fixed it by enabling the respositories using Applications Properties instead of manually adding them.



Cheers!



 

Playing around with MySQL UDFs

Posted In: , , , . By Sid

Okay, so I've been trying this since a long time and it wasn't working ... but I got some help and now it's working, thanks to Roland Bouman.

The end goal is as such:

Consider the tables inbox, ads, outbox. Everytime text is inserted into the inbox table a function should be called which analyses the inserted text and performs one of two operations:
1] Either the text should be inserted into the ads table, with correct specifications about what kind of ad it is.
2] The text should still be analysed and on the basis of that analysis a set of ads should be extracted from the ads table and this set should be pushed into the outbox table, to be sent out by an SMS gateway.


Now unfortunately for me, being the amateur that I am, I painted myself into a corner by selecting FLEX to generate the lexical analyser or text analyser. Never select technology without understanding the true meaning of flexibility. I would never have spent so much time against a wall, had I been able to re-write the (couple of thousand) lines of code the analyser is in, into MySQL code.

In technology terms I had to somehow ensure that a MySQL trigger would call the analyser code which would call further MySQL code.
1] MySQL Trigger - MySQL.
2] Analyser - C.
3] Further db processing - MySQL/C?

So the question arose how to go about accomplishing said goals.

MySQL UDF's:
These User-Defined-Functions allow you to install C functions as MySQL functions. It's really quite cool, kudos to the guys at MySQL for this beautiful extension mechanism.
MySQL UDF's.

MySQL C API:
Now the problem further arose, how could I pass on the results of the text analysis to MySQL code? The answer is obvious, write the MySQL db processing in the analyser itself! The UDF's allow you to return only pointers to strings, integers, doubles. No pointers to structures, unless I used some string typecasting...
MySQL C API

Problem that will "kill-you-till-you-die"
Now the problem that arose is that, everytime the MySQL C API would try to spawn a new connection it would return a "Cannot connect to server(111)" error.

I pegged it as "the client could not spawn a new connection from within the connection it was in".

According to the manual, the seventh parameter to the mysql_real_connect() unix_socket is not NULL, the string specifies the socket or named pipe that should be used. Ergo, it piggybacks the socket your already connected client uses instead of trying and failing to create a new one.

In my case, it was /tmp/mysql.socket

And now, problem solved.

A trigger on the inbox calls the function which analyses the text inserted into the inbox table and on the basis of that either inserts it into the ads table or retrieves a set of ads from the ads table and pushes an outgoing message into the outbox table.

VOILA!

Last night I spent an anguishing two hours on this small problem, before getting badly irritated and watching half of a really horrid movie.



The Regexp.test(String) function in Javascript is called as:



/^[A-Za-z]/.test("abcd");



The above expression is to test weather a string starts with a letter or not.



This is NOT the same as:



var x = "/^[A-Za-z]/";

var y = "radio-gaga";

Regexp(x).test(y);





When you pass anything to the Regexp() constructor make sure it's not delimited by the '/'s. Ergo, what works is:



var x = "^[A-Za-z]";

var y = "radio-gaga";

Regexp(x).test(y);

Assumes your filename is test_example.c and your output file will be test_example.so and you have MySQL installed in /usr/local/mysql/ with the --with-embedded-server option enabled when you configured the script.


"Murder, Mayhem"
Otep - Nein.

 

I would not recommend doing this. Use synaptic as far as possible, it's way cleaner and faster. In my case, I needed some additional configuration ergo I used source.

1. Step one download the source from the official MySQL downloads page. Pick the community server, and select the MySQL source tarball.

2. I referred to this wiki about how to install MySQL on Ubuntu from source most of the time, but somewhere down the line it failed me. Anyways, on with it. After downloading, extract it using:


tar xzvf mysql-yourversionnumber.tar.gz


3. Before you proceed you need to install three packages. build-essentials, libncurses5 libncurses5-dev. I used synaptic to do this.

4. Now, add a user and group allowing MySQL to run.

sudo groupadd mysql
sudo useradd -g mysql mysql


5. Now, change your directory to the one you just extracted into and use the following options for the configure script.


./configure \
--prefix=/usr/local/mysql \
--with-mysqld-user=mysql \
--without-debug \ (I didn't use this)
--with-client-ldflags=-all-static \
--with-mysqld-ldflags=-all-static \ (In case you want to enable dynamic loading use -rdynamic)
--disable-shared \ (I didn't use this)
--localstatedir=/usr/local/mysql/data \
--with-extra-charsets=none \ (I didn't use this)
--enable-assembler \ (I didn't use this)
--with-unix-socket-path=/tmp/mysql.socket


The options I used are as below, note, I used rdynamic for dynamic loading, so that I can call C functions within MySQL statements. I used the with-embedded-server option so that I can use the lmysqld library which compiles the MySQL C API which allows me to write MySQL code within a C program.


./configure \
--prefix=/usr/local/mysql \
--with-mysqld-user=mysql \
--with-client-ldflags=-rdynamic \
--with-mysqld-ldflags=-rdynamic \
--localstatedir=/usr/local/mysql/data \
--with-unix-socket-path=/tmp/mysql.socket \
--with-embedded-server


6. After this is done.


sudo make
sudo make install


The make took some time on my machine, at this point go read a book :)

7. Okay, now once this is done. What you need to do is setup the config file for MySQL giving it some default paramters for its connections.

sudo cp support-files/my-medium.cnf /etc/my.cnf


This is assuming you're still inside the MySQL-yourversionnumber directory you extracted the downloaded tarball in.

8. Now you've got to create the GRANT tables. This is easy just run a pre-provided script.

sudo /usr/local/mysql/bin/mysql_install_db --user=mysql


9. Now, you need to setup permissions. Here is where I messed up real bad, like took me two days to get it right after four OS re-installs bad.

So, the wiki says you need to do this.


sudo chown -R root /usr/local/mysql
sudo chown -R mysql /usr/local/mysql/var
sudo chgrp -R mysql /usr/local/mysql


Which looks all good, but my install didn't have a /usr/local/mysql/var directory and it erred here, which lead to another error in the next step. That is the step when you setup the MySQL daemon.

Instead, if the code above gives you an error. Go for this. Make sure you change to the directory you installed MySQL in, i.e. /usr/local/mysql/

chown -R root .
chown -R mysql data
chgrp -R mysql .


10. Once that's done. You need to start up the MySQL daemon (process which runs in the background)

/usr/local/mysql/bin/mysqld_safe -user=mysql&


If this doesn't say something bad like STOPPED then you're in the clear.

11. Set a password for the main user.

/usr/local/mysql/bin/mysqladmin -u root password 'new_password'


Login:

/usr/local/mysql/bin/mysql


12. Now, we setup the daemon to start itself automatically when your PC boots up.

sudo cp support-files/mysql.server /etc/init.d/mysql
sudo chmod +x /etc/init.d/mysql
sudo update-rc.d mysql defaults


Again, make sure you're still in the same directory that you extracted all the files in.

And you're done!

In the 12th standard I left 16 marks in my HSC English paper, I just turned over the question and didn't write 16 marks. I felt so sad after realizing what I had done, I took an hour of my day and thought it over. I vowed to crack the next paper, which was Chemistry a fairly difficult subject for someone of my memorizing capabilities.
I got a 98 in Chem. I'd never studied as hard as that.

Two minutes ago I broke a small promise. Eyaargh! I hate it when that happens.

The point is, sometimes I mess up, but where you're from matters hardly half as much as where you're going.

So now the question is, where am I going?
