The Google Go Experience

I have always wanted to check out the Go language sooner but unfortunately enough couldn’t have a go… Today I googled if there are any debian packages for Google Go and luckily I found one… It’s of course not an official release from the Go team. Still it interested me. I downloaded the file and installed the package. Yeah, it works! This is the first time I am playing with Go, so no issues have been encountered. But the debian package requires me to overwrite some of the GCC files. Again, I am not a serious C/C++ programmer, so I don’t know if that has damaged my GCC to any extent.

Oh yeah, I forgot to mention I am on Ubuntu 9.04 🙂 I downloaded the package from this link: http://drop.io/gccgodeb/asset/gccgo-4-5-0-1-i386-deb

It’s nearly a 27 MB of download. I downloaded and double clicked to install it. The installation failed with some errors. So, I pointed back to the Original Source Page (Author’s Blog Post) of the package and re-read carefully. I had to use the command line to set “–force-overwrite” mode to the dpkg utility so that it could overwrite files at it’s discretion. Here’s the command:

sudo dpkg --force-overwrite -i gccgo_4.5.0-1_i386.deb

1	sudo dpkg --force-overwrite -i gccgo_4.5.0-1_i386.deb

Now, for quick demo, I downloaded the sample “Hello World!” source code from the official Go website at http://golang.org/ 🙂 (Hey, wasn’t it http://go-lang.org the last time I visited it? No way, both URL works now 😀 )

package main

import "fmt"

func main() {
  fmt.Printf("Hello, ??\n")
}

package main

import "fmt"

func main() {

fmt.Printf("Hello, ??\n")

}

PS: I am sorry that my Syntax Highlighter doesn’t yet have the Go syntax highlighting patterns. Neither does my code editor! But still I used the code block, just out of a good practice! 😛

Then I compiled the source (after naming it masnun.go) with the following command:

gccgo masnun.go

1	gccgo masnun.go

It created the file a.out . I ran it from the command line again:

masnun@ubuntu:~/Desktop$ ./a.out
Hello, ??
masnun@ubuntu:~/Desktop$

masnun@ubuntu:~/Desktop$ ./a.out

Hello, ??

masnun@ubuntu:~/Desktop$

It was pretty easy in fact! I am going to play with Go at my leisure to check out what it has to provide the developers with… I love Python, let’s see if Go can give me anything more than Python 🙂

Thanks to Google, we have another programming language to do our bidding! Happy programming!

Sending Mail Via Postfix: A perfect Python Example :)

8 Comments on Sending Mail Via Postfix: A perfect Python Example :)

I have been playing with Postfix for the last couple of days. I have already posted a perfect php class for sending email with attachments in a previous post. The Python example I posted earlier does the job for me but it was not perfect like the php one.

After digging a while, I found a nice way to do the same for python as well. I have just tested the codes and the result is perfectly what I desired 🙂

Here’s the code:

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
import os

def sendMail(to, fro, subject, text, files=[],server="localhost"):
    assert type(to)==list
    assert type(files)==list


    msg = MIMEMultipart()
    msg['From'] = fro
    msg['To'] = COMMASPACE.join(to)
    msg['Date'] = formatdate(localtime=True)
    msg['Subject'] = subject

    msg.attach( MIMEText(text) )

    for file in files:
        part = MIMEBase('application', "octet-stream")
        part.set_payload( open(file,"rb").read() )
        Encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment; filename="%s"'
                       % os.path.basename(file))
        msg.attach(part)

    smtp = smtplib.SMTP(server)
    smtp.sendmail(fro, to, msg.as_string() )
    smtp.close()

# Example:
sendMail(['maSnun <masnun@gmail.com>'],'phpGeek <masnun@leevio.com>','Hello Python!','Heya buddy! Say hello to Python! :)',['masnun.py','masnun.php'])

import smtplib

from email.MIMEMultipart import MIMEMultipart

from email.MIMEBase import MIMEBase

from email.MIMEText import MIMEText

from email.Utils import COMMASPACE, formatdate

from email import Encoders

import os

def sendMail(to, fro, subject, text, files=[],server="localhost"):

assert type(to)==list

assert type(files)==list

msg = MIMEMultipart()

msg['From'] = fro

msg['To'] = COMMASPACE.join(to)

msg['Date'] = formatdate(localtime=True)

msg['Subject'] = subject

msg.attach( MIMEText(text) )

for file in files:

part = MIMEBase('application', "octet-stream")

part.set_payload( open(file,"rb").read() )

Encoders.encode_base64(part)

part.add_header('Content-Disposition', 'attachment; filename="%s"'

% os.path.basename(file))

msg.attach(part)

smtp = smtplib.SMTP(server)

smtp.sendmail(fro, to, msg.as_string() )

smtp.close()

# Example:

sendMail(['maSnun <masnun@gmail.com>'],'phpGeek <masnun@leevio.com>','Hello Python!','Heya buddy! Say hello to Python! :)',['masnun.py','masnun.php'])

I should feel sorry now that 2009 is leaving me, leaving us! I have had the most eventful year in 2009 🙂

First things First
What were the things those happened first time in my life?

— I sat for University Admission test.
— Got chances in SUST CSE and 4 disciplines in KU.
— My University life began.
— Started free lancing seriously.
— Started earning money at a regular interval.
— Went to BAD picnic and my first tour with the BAD family into the Sunderbans 🙂
— Joined my first Job (At Leevio as a software engineer).
— Attended the first ever FICC.
— Stood 3rd in my first Uni term final 🙂
— Started using Ubuntu seriously
— Started working with WP API
— Worked on GAE and other Python stuff 🙂

What else?
— BAD won the cricket championship. I was an active part in the gallery.
— Met a bunch of cool friends.
— Lost a few fake ones as well.
— My brother got chance in Khulna Zilla School 🙂

Wishlist for 2010
I would wish only one thing — A laptop in 2010 🙂

I am really contended with what I have got in life. I am happy with what I got in 2009. Thanks to the Almighty Allah for everything HE has blessed on me 🙂 I just pray that nothing bad happens in 2010 😀

I pray to the Almighty so that HE bestows his blessings upon those who have a worse life than me. I have nothing more to expect 🙂

Good Bye 2009, Welcome 2010! 🙂
