Convert JPEG files to pdf

Trên Ubuntu 11.10

sudo apt-get install imagemagick: Đã có sẵn, không cần cài.

Danh sách file:

scan-_0000_Layer 8.jpg
scan-_0001_Layer 7.jpg
scan-_0002_Layer 6.jpg
scan-_0003_Layer 5.jpg
scan-_0004_Layer 4.jpg
scan-_0005_Layer 3.jpg
scan-_0006_Layer 2.jpg
scan-_0007_Layer 1.jpg

Convert lần 1:
convert scan-_000* output.pdf
thất bại vì thứ tự ngược, đánh số từ 7 tới 0 chứ không phải từ 0 tới 7.

Rốt cuộc, đành phải chạy bằng tay:
convert scan-_0007_Layer\ 1.jpg scan-_0006_Layer\ 2.jpg scan-_0005_Layer\ 3.jpg scan-_0004_Layer\ 4.jpg scan-_0003_Layer\ 5.jpg scan-_0002_Layer\ 6.jpg scan-_0001_Layer\ 7.jpg scan-_0000_Layer\ 8.jpg output2.pdf

Thực ra nếu trong tên file không có space thì chạy luôn:
convert `ls -r1 *jpg` output3.pdf

Chuyện linh tinh, note lại cho vui :)

How to report bugs effective (diet version)

Đây là cách viết bug report đơn giản và hiệu quả.

1. Summary: Sơ lược về lỗi
2. What did you do? Anh/chị đã làm thế nào mà lỗi xảy ra (tức là cách
tái hiện lỗi)
3. What happened? Lỗi xảy ra như thế nào? (chạy sai)
4. What should have happened? (Lẽ ra chương trình phải chạy thế này)
5. Và evidence (log, screenshot...) nếu có.

The Internet, January 16, 2012 - The Document Foundation (TDF)
announces LibreOffice 3.4.5, a new improved version of the
award-winning free office suite for Windows, Mac and Linux, solving a
number of bugs and further improving the stability of the program.

LibreOffice 3.4.5 represents the best choice for a free office suite
for every user, including conservative corporate users who were still
deploying LibreOffice 3.4.4.

In 2011, LibreOffice has won InfoWorld's BOSSIE Award 2011 as Best of
Open Source Software, and the Open World Forum Experiment Award of
Most-Popular Software. The awards are a demonstration of the key
improvements brought to the legacy code by a small army of close to
400 TDF developers.

LibreOffice 3.4.5 is available for immediate download from the
following link: http://www.libreoffice.org/download/. Extensions for
LibreOffice are available from the following link:
http://extensions.libreoffice.org.

Change logs are available at

(fixed in 3.4.5.1) and

(fixed in 3.4.5.2).
