You are in the middle of doing your work, suddenly you realized your computer hang up. But the problem is, you have not saved your work! Dont panic! There is a solution for that! And you can surely save your file!

Heres how:

Yes, Bluetooth, which took years to get catch on, seems to be reaching a tipping point.  You can tell because even mid-priced automobiles now incorporate it. Thus it has become a telecommunications tool for small and mid-size business people — not just a luxury technology for Fortune 500 executives anymore.

Bluetooth technology has been around for a dozen years.  For much of that time it was an obscure technology that not many people used.  According to research firm IC Insights, shipments of Bluetooth were virtually nil as recently as the year 2000. 

We should not be surprised by the slow uptake. It’s got an unusual name, which is hardly descriptive. Most people I know had no clue what Bluetooth actually was for the longest time — and were afraid to ask.  And until recently, there was also the issue of the price. I actually had Bluetooth in my BMW back in my corporate days (now I’m an entrepreneur and these days can only afford Toyotas).  But back then it was a super expensive option — almost $2,000 and had to be special ordered and took months to get.

In the last year or two, that seems to have changed.  Suddenly Bluetooth is everywhere you look.  The trend is expected to continue with Bluetooth becoming even more ubiquitous.  According to IC Insights, shipments of Bluetooth are forecast to rise 47 percent during 2007.

Bluetooth is a wireless technology.  It is commonly used to let you access your cell phone with a wireless headset.

All those people sitting in airports and standing in checkout lines appearing to talk to thin air – no, they’re probably not Secret Service agents.  They are just using Bluetooth.  If you look closely, you’ll see they’ve got small Bluetooth earpieces over one ear.

Bluetooth has other uses besides the cell phone.  For instance, you can use it for a wireless headset to listen to music, or to wirelessly connect a mouse to a laptop.  It has a fairly short distance range – six to 30 feet is typical. Essentially it creates a wireless cloud around a small area.

Bluetooth is a great liberator for entrepreneurs and business owners.  It takes the mobile convenience of the cell phone to the next level.  A Bluetooth headset is not nearly as unwieldy as a corded headset for your phone.  With your phone on your desk, you can move around in your office easily.  You will still have your hands free to take notes or look up important information on your computer.  Clip your phone to your belt or on your purse and you can be anywhere and conduct business.

One of the most interesting places where Bluetooth is showing up is in the car. With hands-free Bluetooth integration in your car, and features such as dial by name capability programmed into your phone, you can even call that client while on the road to let him or her know you’ve run into traffic and will be late.

Today, even mid-priced automobiles like my Toyota RAV4 come with integrated Bluetooth to allow you to talk hands free using the car’s stereo speakers.  You can buy a variety of Bluetooth aftermarket car kits, too.

Why is Bluetooth seemingly everywhere all of a sudden?  Several factors:

1. Today the public is more aware of the dangers of trying to drive a car while holding a cell phone in one hand.  Some might argue that the driver is still distracted with a hands-free phone, but at least both hands are on the wheel.
2. Bluetooth chipset technology has dropped in price, making Bluetooth devices more affordable.
3. The technology has improved, working seamlessly with more cell phones and other electronic devices.  It’s more secure.  There are now smaller wireless headsets, and more choices. Many of the world’s major electronics manufacturers, such as Motorola, offer Bluetooth products.  You can even buy such interesting gadgets as Bluetooth sunglasses.

And with prices that continue to drop, Bluetooth is affordable even for startup entrepreneurs on a tight budget.  A brand-name Bluetooth headset can be purchased for as little as $30.  Factory-installed Bluetooth capability in a new car goes for as little as a few hundred dollars in some models.

Serakah.. kemaruk besar.. kepala.. lupa diri
Campur aduk menjadi satu

Berkacalah …
apa yang kau lakukan pada negeri ini
apa yang kau berikan pada negeri ini
apa yang kau sangsikan pada negeri ini

ingatlah….
semua ada yang mengatur
semua akan ada balasan-Nya
semua akan kembali pada-Nya

Saling tuduh…
sumpah serapah…
caci maki …
menjadi satu alunan yang merdu bagi kita semua

Hai kamu semua….
Eling lan Waspodo
Sing becik bakal ketitik
Sing Olo bakal Ketoro

There are several variables related to port range in sysctl, mine is different from the default value, although I didn’t modify anything.

I can’t bear the annoying automate login attempts any more and decided to give it a try. It’s easy to change:

Add a line in the file /etc/ssh/sshd_config:
Port 3456

Reload sshd
#/etc/rc.d/sshd reload

I opened another putty client to test the login, everything worked fine. The great thing is the old ssh connection is still active after the sshd modification and reload, I always have the chance to revert the configuration back if it doesn’t work.

To protect its exploiters of phishings, Yahoo! converted its log-in authentication communications protocol, as they declared June 16. The newly protocol asked a specific authentication process edition on the client end and refused access if it didn’t match. IM services Pidgin and Kopete were recently affected by this.

Pidgin developers comprised the first to respond to the crisis. They had discovered the authentication protocol modification done debug reports from the proprietorship Yahoo Messenger from Xandros, the only Linux guest still using Yahoo!, and returned to an more previous host version. The number of servers still using the old authentication communications protocol is steady dwindling, thereby doing higher opportunities of connectivity troubles. Pidgin opposed by disenabling old versions of Yahoo Messenger in their up-to-date version 2.5.7 and supporting Yahoo!’s revised protocol. Pidgin users should from now on be using the update and targeting the scsa.msg.yahoo.com server.

The Kopete IM service acknowledged as is trouble and attached the new Yahoo! authentication to its Subversion repository on Midsummer’s Day, to estimate from a web log by developer Matt Rogers. Rogers also asked a retagging of KDE to include the fix for the KDE 4.3 release coming up in July.
