Sailing with Lili from Winthrop Harbor, Lake Michigan

Sailing with Mark 

SDM

Wyjechałem, i ślad mi po tobie zaginął
życie już przeminęło, a nawet dzień nie minął,
dobre, stare małżeństwo nas już wyuczyło
jak cierpieć pięknie, jak kochać, i co nas tam łączyło

kto by mnie zrozumiał, o czwartej nad ranem,
na Manhattanie, czy gdzie-bądź tam bywałem,
kto gitarę, kto harmonijkę, kto skrzypce zrozumie?
w kajucie pocałunki, siedząc przy ognisku w dumie?

na bacówce wtedy, bogami młodymi byliśmy,
jabłkiem słodkim, grzesznym, życia smakowaliśmy
rodziną kochaną mi byłaś, ostoją jedyną

w mych oczach wciąż jesteś tą samą dziewczyną


Dziś, oczekiwać nie będę, pożądać już nie mogę,
ale być przyjacielem dobrym.. na twą dalszą drogę,
i czasami razem, wyjść na wrzosowisko
i jak w pieśni było, tam zapomnieć wszystko.

Java Servlet: starting a thread that always runs

• when Java Servlet starts it reads web.xml
• add listener implementation class to your web.xml

<display-name>your_servlet_namedisplay-name>

<listener>

<listener-class>com.your_package_name.TimedServletCallerlistener-class>

listener>

• we will use ServletContextListener interface
• create a NEW thread (Loop) inside contextInitialized(), if you did Thread.sleep without new thread the whole Servlet would pause and container would fail to start it after 45 seconds or so

public class TimedServletCaller implements ServletContextListener

{

private static int sleepMinutes = 1;

class Loop extends Thread

{

public void run()

{

while (true)

{

Log.e("Loop is running!");

takeShortNap();

// do stuff here

}

}

}

@Override

public void contextInitialized(ServletContextEvent arg0)

{

Log.e("***** TimedServletCaller.contextInitialized()");

// execute();

Thread thread = new Loop();

thread.start();

}

private static void takeShortNap()

{

Log.i(" Pausing for " + sleepMinutes + " minute(s).");

try

{

Thread.sleep(sleepMinutes * 60 * 1000);

} catch (InterruptedException e)

{

Log.e(e.getMessage());

}

}

• restart your server (Tomcat) now you can use your Servlet, but also the Loop keeps running and doing useful things like database updates, etc.

Starved Rock, Illinois

Chicago area has very few natural attractions (except sailing Great Lakes),

Starved Rock is one of them and a very popular spot to visit.

HD connector speed

When you are buying the external hard drive storage, I would recommend looking for eSATA connectors, backing up, or copying videos via USB is very slow.

USB 1.1 – 15 Mbps
FireWire (1394a) – 400 Mbps
USB 2.0 – 480 Mbps
FireWire 800 (1394b) – 800 Mpbs
SATA 1.5 – 1.5 Gbps
SATA 3.0 – 3.0 Gbps

near future:

USB 3.0 - 5Gbps
eSATA version of SATA 6G - 6.0Gb/s

“I met Uki as the Chicago Leader of GTUG, and at the time I was leading Chicago Androids myself. We hit it off from the start and jointly organized a set of well organized Android and Google tech. related events. Eventually as I left the Chicago Area, Uki took the leadership role for both groups. Uki is a thorough and tireless leader that has done a wonderful job as a host and speaker in multitude of events I attended. You can also tell that he inspires respect and admiration by the way his events are supported by his coworkers and peers.”  April 11, 2010

I am a candle

I am a candle 

which you have tried 

with all your might
to stamp right out, 

and sliced my throat 

for the thousandth time
but one bright night 

she'll light me up 

and I will shine just as bright!



In a vicious battle 

of dark and right, 

life won today, 

took all that's mine

it smothered me; 

it trampled me up 

-- left me for trash

ripped out my heart, 

it's not a wound, 

but a blazing gash

but I am a candle 

and I will shine 

just as bright!

~ Uki

Using HTML panel

I needed to create a subscript text with a link that open up a new popup with different content. Since HorizontalPanel does not work, I used HTMLPanel and use the table tag, which contained element id as shown below.


Click on below image to read the code: CSS

CSS code:

.subscript {

font-size: xx-small;

vertical-align: bottom;

}

.hyperlink_subscript {

text-decoration: none;

cursor: pointer;

color: #0099FF;

font-size: xx-small;

font-weight: normal;

}

White Space "ma" (間)

"ma" (間) - the intervals or pauses in our lives.

In Zen, "ma" (間) is about emptiness and fullness; it is that subtle space or pause between things in Japanese culture, the silence between notes in music, or the gentle gap around a single flower in ikebana (生け花).

It embodies timing, presence, and breath, hinting that emptiness can also hold profound beauty.

In architectural design, “ma” is the quiet buffer that allows each element to breathe freely. It’s a graceful pause that lets our spirit settle and allows us to appreciate what’s truly there.

IE8 and Windows7 hacked easily

I wonder if Mac vulnerabilities would be found this easy if we put effort towards it or does everyone just like to pick on Microsoft?

Evanescence "My Immortal"

I'm so tired of being here
Suppressed by all my childish fears
And if you have to leave
I wish that you would just leave
'Cause your presence still lingers here
And it won't leave me alone

These wounds won't seem to heal
This pain is just too real
There's just too much that time cannot erase

When you cried I'd wipe away all of your tears
When you'd scream I'd fight away all of your fears
And I held your hand through all of these years
But you still have
All of me

You used to captivate me
By your resonating light
Now I'm bound by the life you left behind
Your face it haunts
My once pleasant dreams
Your voice it chased away
All the sanity in me

These wounds won't seem to heal
This pain is just too real
There's just too much that time cannot erase

I've tried so hard to tell myself that you're gone
But though you're still with me
I've been alone all along
