Netbeans will not start? Perhaps it does!

Unable to start Netbeans in Ubuntu, reinstalling it doesn’t help, installing a different version doesn’t help, tried to install from Software Centre, install from terminal apt-get command, install using the offline .sh installer, install different bundle… no luck.

From System Monitor Processes tab, it appears that the Netbeans is running, and the task appear at launcher, but I just can’t find the program on any workspace. Until I found the little 3px line on one of my workspace, on one of the display.

The program window was just too small to be found. No minimum window size? Who know?
Move the cursor onto it, click & drag to resize it, and now I’ve got my Netbeans back.

The program window move the cursor onto it click & drag to resize it Netbeans window

It may happens to any other software that doesn’t have a minimum windows size, or on other operating system. If you have a same problem, don’t reformat your pc 🙂

Linux command – 1.6 – File size & disk space

df – report file system disk space usage

Show information about the file system on which each FILE resides, or all file systems by default.

Usage:

df [OPTION]... [FILE]...

Options:

-a, --all include dummy file systems
-B, --block-size=SIZE use SIZE-byte blocks
-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)
-H, --si likewise, but use powers of 1000 not 1024
-i, --inodes list inode information instead of block usage
-k like --block-size=1K
-l, --local limit listing to local file systems
--no-sync do not invoke sync before getting usage info (default)
-P, --portability use the POSIX output format
 --sync invoke sync before getting usage info
-t, --type=TYPE limit listing to file systems of type TYPE
-T, --print-type print file system type
-x, --exclude-type=TYPE limit listing to file systems not of type TYPE
-v (ignored)
--help display this help and exit
--version output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.

Example: display available disk space

$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vzfs 30G 21G 9.3G 70% /
none 512M 4.0K 512M 1% /dev
/dev/vzfs 30G 21G 9.3G 70% /var/named/run-root/var/run/dbus

du – estimate file space usage

Summarize disk usage of each FILE, recursively for directories.

Usage:

du [OPTION]... [FILE]...
du [OPTION]... --files0-from=F

Options:

-a, --all
write counts for all files, not just directories

--apparent-size
print apparent sizes, rather than disk usage; although the apparent size is usually smaller, it may be larger due to holes in (`sparse') files, internal fragmentation, indirect blocks, and the like

-B, --block-size=SIZE
use SIZE-byte blocks

-b, --bytes
equivalent to `--apparent-size --block-size=1'
-c, --total
produce a grand total

-D, --dereference-args
dereference FILEs that are symbolic links

--files0-from=F
summarize disk usage of the NUL-terminated file names specified in file F

-H
like --si, but also evokes a warning; will soon change to be equivalent to --dereference-args (-D)

-h, --human-readable
print sizes in human readable format (e.g., 1K 234M 2G)

--si
like -h, but use powers of 1000 not 1024

-k
like --block-size=1K

-l, --count-links
count sizes many times if hard linked

-m
like --block-size=1M

-L, --dereference
dereference all symbolic links

-P, --no-dereference
don't follow any symbolic links (this is the default)

-0, --null
end each output line with 0 byte rather than newline

-S, --separate-dirs
do not include size of subdirectories

-s, --summarize
display only a total for each argument

-x, --one-file-system
skip directories on different file systems

-X FILE, --exclude-from=FILE
Exclude files that match any pattern in FILE.

--exclude=PATTERN
Exclude files that match PATTERN.

--max-depth=N
print the total for a directory (or file, with --all) only if it is N or fewer levels below the command line argument; --max-depth=0 is the same as --summarize

--time
show time of the last modification of any file in the directory, or any of its subdirectories

--time=WORD
show time as WORD instead of modification time: atime, access, use, ctime or status

--time-style=STYLE
show times using style STYLE: full-iso, long-iso, iso, +FORMAT FORMAT is interpreted like `date'

--help
display this help and exit

--version
output version information and exit

SIZE may be (or may be an integer optionally followed by) one of following:
kB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P, E, Z, Y.

Examples: display size of a directory

$ du -hs /path/to/dir
9.2G	/path/to/dir

stat – display file or file system status

Usage:

stat [OPTION]... FILE...

Options:

-L, --dereference
follow links

-f, --file-system
display file system status instead of file status

-c --format=FORMAT
use the specified FORMAT instead of the default; output a newâ line after each use of FORMAT

--printf=FORMAT
like --format, but interpret backslash escapes, and do not outâ put a mandatory trailing newline. If you want a newline, include n in FORMAT

-t, --terse
print the information in terse form

--help
display this help and exit

--version
output version information and exit

The valid format sequences for files (without --file-system):
%a Access rights in octal
%A Access rights in human readable form
%b Number of blocks allocated (see %B)
%B The size in bytes of each block reported by %b
%C SELinux security context string
%d Device number in decimal
%D Device number in hex
%f Raw mode in hex
%F File type
%G Group name of owner
%h Number of hard links
%i Inode number
%m Mount point
%n File name
%N Quoted file name with dereference if symbolic link
%o I/O block size
%s Total size, in bytes
%t Major device type in hex
%T Minor device type in hex
%u User ID of owner
%U User name of owner
%w Time of file birth, human-readable; - if unknown
%W Time of file birth, seconds since Epoch; 0 if unknown
%x Time of last access, human-readable
%X Time of last access, seconds since Epoch
%y Time of last modification, human-readable
%Y Time of last modification, seconds since Epoch
%z Time of last change, human-readable
%Z Time of last change, seconds since Epoch

Valid format sequences for file systems:
%a Free blocks available to non-superuser
%b Total data blocks in file system
%c Total file nodes in file system
%d Free file nodes in file system
%f Free blocks in file system
%i File System ID in hex
%l Maximum length of filenames
%n File name
%s Block size (for faster transfers)
%S Fundamental block size (for block counts)
%t Type in hex
%T Type in human readable form

Example: display file system status

$ stat -f /
  File: "/"
    ID: 2b6896ea6511332f Namelen: 255     Type: ext2/ext3
Block size: 4096       Fundamental block size: 4096
Blocks: Total: 2090580    Free: 1663166    Available: 1558309
Inodes: Total: 524288     Free: 421462

Alternative way to display file size using ls command

$ ls -lah filename | awk '{ print $5}'

Floating Point Precision

When ASP CInt( ( 0.3 - 0.2 ) * 10 ) gives you 1, but PHP (int) ( ( 0.3 - 0.2 ) * 10 ) gives you 0;

When MySQL SELECT CAST( 3 * ( 1.0 / 3 ) AS SIGNED ) gives you 1, but MSSQL SELECT CAST( 3 * ( 1.0 / 3 ) AS INT) gives you 0;

How accurate the result you can expect from your web application?

floating point

When your web application is built on top of the myth of the floating point, you can’t even expect 0.1 from JavaScript (0.3-0.2), it gives 0.09999999999999998…

Disassembling HTC Touch 3G

Unlike those wealthy geeks (hint hint), I don’t always have some latest coolest high tech gadgets to unbox.

All I’ve are those broken or antique devices like alarm clocks, electronic toys, radio, laptops, to be assembled.

It all began with ruining my dad’s antique calculator when I was a kid. It wasn’t my fault, he did not keep his screwdrivers away from me, who to blame?

It’s been a long time I didn’t do such thing. My natural instinct is unstoppable again, when my 4 y.o. HTC Touch 3G become untouchable…

HTC Touch 3G

* Problem rectified after replaced the broken digitizer with new one.

It is not safe to rely on the system’s timezone settings

Issue:

  • Warning: date() [function.date]: It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function.
