Nitric Oxide supplements

A nutritional supplement called Glycocarn is believed to increase blood levels of nitric oxide, and has been used to enhanced athletic performance.

Side effects
Enhanced athletic performance may result in over exercising.

Nitric oxide is irritating to the eyes and the respiratory tract. Inhalation may cause pulmonary edema , may also affect the blood , resulting in formation of methaemoglobin. In more severe cases can lead to death.

Supplements story
I have tried many NO supplements over the last 5 years and have just recently found one that is the best! I was a longtime user of Bsn products & still use some & also along the way have tried samples of ALL the others. I was out of my n.o.xplode & was cruisin into gnc to pick up my ever growing pricetagged no xplode when the lady behind the counter (built like a brick****house)told me i’m wasting my money & showed me force factor.. i have been using it for two weeks now & never thought i would be training this intense! i have to force myself to stop cause i think i might hurt myself! even though there is no fatigue! no pain! the pump that i am getting is skin splitting! i’m just sayin.. this is hands down the nitric oxide supplement to get right now!

How to setup Linux as NAS?

Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to heterogeneous clients.

Heterogeneous clients?

• A lot of people use SAMBA instead, as it is also works with any Windows PCs on the LAN. Setting up SAMBA share in Ubuntu is really easy.
• You'll have to use something like uShare if you want to use upnp with xbox 360. 
• You can also run torrent client with remote access on NAS

Over here we use a computer that largely function as a NAS (although it also serves as a web host and database host as well). NFS (Network File System) is really all you need. You can put the remote storage into your file system and when it is mounted, you can write to it as if it were part of the hard disk in the local computer. It isn't secure enough to use across the Internet, but for LAN use, it is fine.

NFS is built into the kernel, or provided by a kernel module. You probably need some support files - exactly what depends on your distro. This is the standard HOWTO:

Security
Are you planning on sharing your filesystem over the internet (not just a LAN)? I really would advise you against that unless you know exactly what you are doing. How about running a web server if you want to make some files public?

How to find my cellphone?

Cellphone is small device and it get out of sight easily. To find the cellphone easier read these simple tips:

• Call it or send free sms from computer so you can hear it ring
• If cellphone is sat to silent, than close the lights to make room darker. There is chance that you will be able to see the cellphone light.
• If the TV or other device that produce noise is on, turn it off so you can hear sounds better.
• If cellphone sat to silent produce sounds when battery needs recharging then just wait a while.
• Lost things get found automatically many times so extensive search may not be the best way to find cellphone.
• Check living room couch. The cellphone may got stucked in there.

Maintaining Perfect Blood Sugar Level

Normally in mammals, the body maintains the blood glucose level at a reference range between about 3.6 and 5.8 mM (mmol/L, i.e., millimoles/liter) (64.8 and 104.4 mg/dL).
  
How to Control Blood-Sugar Levels Naturally?

Sugar is hidden in foods in many forms and is often used in more than one form in processed foods. To help restore healthy blood-sugar levels, avoid all forms of sugar, including sucrose, glucose, maltose, corn syrup, honey, maple syrup, barley malt, and molasses.

To help maintain steady blood-sugar levels, eat a diet high in fiber, especially soluble fiber, which slows down the digestion and absorption of carbohydrates and prevents rapid increases in blood sugar levels.

carbohydrates can easily convert into sugar if consumed

Can you feel your sugar level?

When you skip a meal your sugar level drops so it's good to take a quick snack to increase sugar level again.
Regular exercise and fit body helps lower blood sugar levels. When you feel that you have too much energy start exercising.

 

How to eat Spirulina?

Spirulina is a blue-green algae which is used as a nutritional supplement in many regions of the world. Blue-green algae, also known as cyanobacteria, are famous for thriving in very harsh conditions, and they often store large amounts of nutrients to sustain themselves when their environment is compromised. 
 
How to eat spirulina powder?
You can mix it with a bit of protein shake to dilute the flavor if you don't like the flavor and mix in a blender. That worked great for me in the past when I used the powder. As the blender is running with water/juice or whatever...then add the powder little by little.

Spirulina tablets can be taken with water

Spirulina is a food, so it would make sense that the more you ate of this food, the less you would be hungry for other food.

On top of that, it is probably the best food on this planet!

Best Battery Chargers?

Let's see how compare different battery chargers..

• Number of batteries that can be charged
  Bigger number of battery slots gives opportunity to charge large number of batteries without using quick charging that may reduce battery lifespan
  
• Supported bateries types
  If you have many devices that use rechargeable batteries consider buying charger that can charge different battery types.
  
• Auto turn-off function
  Charging full battery use electricity without need and reduce battery lifespan
  
• Charging speed
  Higher charging speed allows to charge batteries when in hurry, many times you are in hurry and can't charge all night long.

Other features: testing, discharging, reconditioning (multiple discarge), etc.

-rw-r--r-- 1 pavlo pavlo 3.4M 2007-05-15 05:53 handbook.pdf
drwxr-xr-x 2 pavlo pavlo 4.0K 2007-04-10 00:25 iso
ls iso/
rhel-5-client-x86_64-disc6.iso

cd - change directory (navigate to some directory):

Code:

cd iso

Code:

cp ../handbook.pdf .

mv - move a file (also used to rename files):

Code:

mv handbook.pdf howto.pdf

rm - remove a file:

Code:

rm handbook-draft.pdf

mkdir - make directory:

Code:

mkdir new

pwd - show your current location:

Code:

pwd
/home/pavlo/example/iso

date - display date and time

Code:

date
Tue May 15 06:07:45 UTC 2007

some commands are distribution specific, such as apt in Debian. Example:

Code:

Which bluetooth stereo headset?

Which bluetooth stereo headset should I choose? The same manufacturer as bluetooth device is recomended. This should bring best compatibility although the bluetooth has own standards. Most headsets have built-in microphone. Headsets differ in weight, comfortablity, sound and fancy look. Now let's have a look at some headsets.

This headset seems to be good for running but it's not as good.

.

Weight is also very important when moving but often not cheap. Well you can always buy second hand (why?)

Classical headset  for voip communication. If one ear is not covered even better so you can listen to environment sounds. Microphone in front of mouth offers best sound.

This headset comes with some controls for music and telephony. It has build in small microphone. See also our Guide to communications equipment.

Install GUI for Ubuntu Server - Useful commands

Xubuntu vs. Kubuntu Comparison

What is the difference between Kubuntu and Xubuntu?


System requirements:

• Kubuntu require 512 MB Ram to install (Xubuntu 192 MB)
• Xubuntu will work faster especially on older computers
• 8+ GB hard drive for comfortable install and updating (both)

Xubuntu is lighter version of Ubuntu and was designed for older computers while Kubuntu use heavyweight KDE desktop suite.

Xubuntu is Ubuntu with Xfce desktop

Xubuntu use simple Xfce desktop instead of Gnome and lightweight programs like AbiWorld and Gnumeric instead of memory hungry KOffice that come pre-installed with KUbuntu. 

What's official?

Kubuntu is "the official Ubuntu derivate" so it has better compatibility with upgrade system, packet management and online support. More websites and tutorials usually talk about "Kubuntu"


Summary:

Xubuntu is easy enough for a first Linux install for determined beginner that have used computer. Kubuntu is great and simple choice for new computer and people who are familiar with KDE. Both can be installed by total beginner and offer decent Linux experience.

Steampunk decoration items

These steampunk items were spoted in a shop window and I decided to make a shot. What really made the decision was steampunk-like decorated wine bottle. Drink responsibely.

Acutally the shop style is more like clean tech lines, with silver color and metal feel...
