Picasa for Mac, akhirnya…

Posted on by
2

Saya adalah seorang pengguna Picasa, sebuah perangkat lunak dari Google untuk organizing dan editing file-file foto yang ada di komputer kita. Selama ini Picasa hanya bekerja di sistem operasi Windows dan kemudian dapat berjalan pula di Linux (via WINE). Sayangnya Picasa versi Mac waktu itu belum ada. Ini yang jadi agak menyusahkan saya sebagai pengguna Mac (pindahan dari Windows & Linux sebelumnya :P). Walaupun sebenarnya ada sih plugin untuk iPhoto yang dapat membantu kita untuk upload foto-foto digital kita ke Picasa Web Album (PWA).

 
Nah, sekarang pada Mac users yang juga pengguna Picasa dapat bernafas lega. Tanggal 5/1/2009 kemarin Google telah mengumumkan bahwa versi Beta dari Picasa for Mac telah dapat di download dan digunakan. Picasa ini dapat digunakan sebagai alternatif untuk iPhoto-nya Mac.

[Linux] Merge Multiple PDF Files Into One File

Posted on by
2

I’m using Linux Mint on my Dell GX260 desktop. It’s another Linux distro based on (and compatible with) Ubuntu Linux. Therefore this installation tutorial might be more suitable for you who’s using Ubuntu and anyother distro based on it. But overall, you can install the package on any Linux distro you’re using now.

1. Install Ghostscript  (PostScript and PDF language interpreter and pre‐viewer), use command:

# sudo apt-get install gs

sudo apt-get install gs

2. Install PDFtk (A handy tool for manipulating PDF), using command:

# sudo apt-get install pdftk

sudo apt-get install pdftk

3. run the command line

Merge 2 files (or more) into one file:
pdftk doc_1.pdf doc_2.pdf doc_3.pdf cat output doc_combined_123.pdf

pdftk

Other Commands:

Using Handles:
pdftk A=doc_1.pdf B=doc_2.pdf cat A B output doc_combined_12.pdf

Using Wildcards:
pdftk *.pdf cat output doc_combined.pdf

Split Selected Pages from Multiple PDFs into one new PDF file:
pdftk A=one.pdf B=two.pdf cat A1-7 B1-5 A8 output combined.pdf

Encrypt a PDF using default 128-Bit Strength and Withhold All Permissions:
pdftk mydoc.pdf output encrypted_doc.128.pdf owner_pw your_password_here

Same as Above, Except a Password is Required to Open the PDF:
pdftk mydoc.pdf output encrypted_doc.128.pdf owner_pw blablabla user_pw helloworld

Same as Above, Except Printing is Allowed (after the PDF is Open):
pdftk mydoc.pdf output encrypted_doc.128.pdf owner_pw blablabla user_pw helloworld allow printing

Decrypt:
pdftk encrypted_doc.pdf input_pw helloworld output decrypted_doc.pdf

Sigma 30mm f/1.4 EX DC

Posted on by

 Anyone (specially Nikon users) have ever use Sigma 30mm f/1.4 EX DC? I have and I’m satisfied with it.

So, what is about this lens anyway?

  • Large Maximum Aperture of F1.4
  • The most appropriate coating for digital SLR cameras
  • Two SLD (Special Low Dispersion) glass elements and an hybrid aspherical lens, provides the utmost correction for all types of aberrations
  • Equipped with HSM (Hyper Sonic Motor) system. IT WORKS for Nikon D40/D40x/D60 for autofocus

I bought it because i want to have a big aperture lens to shoot in low light. My D40x kit lens (18-55mm) was way out of it. Buying Nikkor 50mm/f1.8 or 1.4 also not an option because it cant do autofocus in my D40x. Well, then I found this Sigma 30mm f/1.4 EX DC.

With 1.5x crop factor sensor of my D40x (now D80), at 30mm it becomes a 45mm lens equivalent. So this lens is perfect to shoot for street photography and general shots. I tried to shot the lens wide open at f/1.4. This lens puts a new spin to street photography at night WITHOUT a tripod. At f/1.4, image quality in very low light conditions with a minimum shutter speed of 1/30 and an ISO setting of 800 or higher – made some pretty nice images.

When you stop down to about f/1.8 to f/2 under low light conditions, the image quality just seems to improve and sharpness and detail improves. Under normal lighting conditions, this lens seems to be sharpest at f/4 – f/5.6.

Nah ada yang mo sharing soal SETTING/KONFIGURASI koneksi Flash dengan modem dan O/S pilihan masing-masing? Bisa email atau taruh link di comment box deh :) Kalo soal network quality jangan komplain ke saya yah. Terus terang saya ga bisa bantu heheheheh tapi kali-kali ajah ada officer Telkomsel yang berkompeten dengan layanan tersebut yang mantengin blog saya ini (seperti halnya telkomsel blackberry prepaid)

Installing MySQL for Python on Mac OSX Leopard

Posted on by

Yesterday, I have a sudden request from sysadmins group to make a web data presentation from their OVO data. I’ve already had some kind of template for the web apps using CodeIgniter based framework. The only “work” to do now is how to get, process and displaying the data from raw. It’s gonna be supplied via text file.

So, I came up with an idea to use Python to do collection, conversion and inserting into database :P Ya ya ya, I actually I just wanna try to learn Python and use it in a production environment :D So, it’s gonna be my first Python application hehehehehe.

My yukiyanagi (MB403LL/A MacBook) is already equipped with Python 2.5.1. Done with file checking, reading, parsing etc. It’s now time to put all parsed data into database.
What you need to do are:

  1. Download MySQL from dev.mysql.com/downloads and install it as instructed in the documentation.
  2. Download and extract the MySQL for Pythom from sourceforge.net. I’m using MySQL-python-1.2.2.tar.gz
  3. Open Terminal and go to the directory where MySQL-python-1.2.2.tar.gz was unpacked to.
  4. It’s better to delete build/ directory, just in case your installation might be interfered with any previous builds
  5. edit file site.cfg, and edit the value of mysql_config to the correct PATH where your mysql_config reside. Mine is:

    # The path to mysql_config.
    # Only use this if mysql_config is not on your PATH, or you have some weird
    # setup that requires it.
    mysql_config = /usr/local/mysql/bin/mysql_config

  6. After that, run the build and installation script.

    python setup.py build
    python setup.py install

During “python setup.py build”, you might have some problem here like I did. It seems that there is an extra ‘mysql’ in the path that the shared object looks for the .dylib. You may get an error like this:

ImportError: dlopen(./_mysql.so, 2): Library not loaded: /usr/local/mysql/lib/mysql/libmysqlclient_r.15.dylib

Referenced from: ./_mysql.so
Reason: image not found

The solution is by making a symlink from /usr/local/mysql/lib to /usr/local/mysql/lib/mysql

cd /usr/local/mysql/lib
ln -s /usr/local/mysql/lib mysql

Another error which might be occured is gcc related like the picture below:
MySQL for Python installation error

Line 47 of /usr/local/mysql/include/mysql.h is:

#include <sys/types.h>

Line 93 (and 93) of /usr/include/sys/types.h is:

typedef unsigned short ushort; /* Sys V compatibility */
typedef unsigned int uint; /* Sys V compatibility */

All you need to do is comment those 2 lines (dont forget to make the backup first)
and do the “python setup.py build”.
Voila! Everything will be running well.
