How to achieve efficiency?

We live in a society where everything evolves faster and faster and it needs to be easier to.

It's human nature that we want to get faster and better tools then we already have, we have always want to be better, faster and more efficient. On the work floor we speak of operation efficiency. There are even people who only work on ways to improve their business efficiency. They use mind-maps, charts and other methods to analyze what can be improved. Seeing or doing things different can also lead to efficiency. The opposite is also possible, less efficiency than before has to be detected as soon as possible and the cause of that has to be corrected as soon as possible to counteract deterioration.

Efficiency is often associated with easy. And this is true, but that is only correct for the final solution and the implementation of the tasks themselves.

Before you can achieve efficiency, you mostly need to solve a problem. And in order to solve that problem you need clever and creative persons who need that little dare combined with a problem solving brain.

We clarify efficiency here on the basis of an example.
The problem: Solving complex calculations in a simple way.
The solution: The program Excel, the tool of choice to solve difficult calculations. Enter some numbers in the cells, write a formula in another cell and you have your solution in no time.

Most people don't realize it but before you even could dream of this solution there was a very long and complicated process preceded before this solution has been reached. A computer program as "excel" needed to be invented. Without such a program, we were forced to use slower systems such as a calculator or our own brains, with many formulas had to be written out.

But such a program would never come there when nobody would have invented the computer. And the computer would not have been there if the transistors, and many chips aren't invented at first if we didn't made the radio first. So we can go on this way, until we arrive at the invention of the wheel. Everything depends on one another. One can not exist without the other. But the other must first be invented, so we can invent another. And therefore we need creative humans with a clever mind to make inventions.

Evolution
In the evolution of the wheel to where we are now, there is a constant that I just want to enter: Time, and speed. The first inventions took thousands of years to evolve, but according to the more inventions existing the faster new things could be invented. This means that we live in a constant acceleration, where everything evolves faster and faster. On this day, a single person can not keep up as we could do in prehistoric times. But everything of course began in the prehistoric times, when some creative types invented the first wheel, the first spear, the first huts, the first animal husbandry and many more. By increase efficiency you can not only do more but you and everything around you can improve so things get better or work faster than before.

Conclusion
The preparatory work of an efficient system is often very complicated. We need thous clever inventors with their creative, problem-solving spirits who need just that little bit courage to go further. Do you know the ones who invented something by putting their teeth into a project and never let that go for the rest of his life? Those are the people who change the world, and improve efficiency and making everything easier, so we can achieve more on an easier and more efficient way.

We need to be grateful for the creative minds here on earth.

How to make the smallest jpg files with no quality loss for my website

Since Google does worry about the page load speed of websites. Maybe you checked the loading time of your website checked with PageSpeed ​​Insights from Google and you want to have your graphic files with lossless compression.
You also want to let your website load very quickly in the browser of your visitor. Because users of your website don't want to wait any second longer as necessary. They will leave your website if it's has a long load time. And another advantage: Google can crawl your WebPages faster, that means Google crawl more pages in a same time-segment.

To get the smallest jpg files for your website you can use the free FastStone PhotoResizer.

To get the smallest files without quality loss with this program you need to set some settings right.

The JPEG Format Settings
Set the Quality to 75 percent.
Photometric settings: make no change.
Color Subsampling can be set to High (Smaller File Size).
Smooting: 0 to avoid blurry images.
Check on the Optimize Huffman table.
Check on the Progressive mode. This option let the browser load jpg files in phases from the website, and makes the files much smaller.
Uncheck the Keep EXIF / IPTC Data.

Check on Use Advance Options and click it to set the options
If necessary resize them to a smaller size.
Set the filter to Lanczos2 (Sharper), for no quality loss.
Set the DPI to 96 or 72 for x and y, there's no need to set this higher because a computer screen have a maximum of 96 dpi that they can display, and a website is always seen on a computer screen. The web is not made to be printed. Now you can save the options to a file and load this settings at any time.

Speed is everything
Now you know to make the smallest and fastest jpg files for your website. A big improvement for your website load speed means also more visitors that stay on your website and a less loading time means that visitors read more pages in less time because they don't need to wait for loading big jpg files.

Network cable speed recognition and what type of network cable do you need in which case


There are plenty of networking opportunities and network cables available. But there are so many types of network cables that it's difficult to know witch type of network cable you exactly need.

Witch network cable do I need?
If you want to work with Cat5e and Cat6 than you need a 1000 Mbps network switch (Ethernet Switch) for a remarkable improvement in the throughput of the data. Several network cables with category Cat5 connection to a 1000 Mbit switch goes also. For example, with 10 PCs connected to a network with Cat5 network cables you can get maximum speed of 100 Mbits 1 computer can still reach there maxiumum speed of the 1000 Mbit swich.

A 1 GB network that does not mean there goes 1GB over the cable, but the data goes in pairs added together,250 MB in 1 pair.

Types of data speeds of network cable
Cat4 10 MBit = 1,25 MByte
Cat5 100 MBit = 12,5 MByte
Cat5e 150 MBit = 18,75 MByte
Cat6 250 MBit = 31,25 Mbyte

On this site you can calculate from Megabytes to MBits and vise versa:

Specifications of network cables
UTP: Unshielded Twisted Pair, the normal network cables.
STP: Shielded Twisted Pair, network cables for in noisy environment.

With Cat5 you have UTP and FTP cables. If you aren't routing the cable along power cables, transformers, fluorescent fixture, etc. than you can use UTP cable. Otherwise you have FTP and FTP cable connectors. In FTP, the equipment must also support FTP. In FTP, the wires and the cable is shielded. The veins of Cat6 cables are always shielded. Cat6 cables are much more expensive. In CAT4 you often see that there are only 2 pairs, 4 threads can be used. Cat4 2 pairs are also used for the transmission of the signals. Cat5 also send the data in 2 pairs. In Cat5e all 4 pairs are used.

Conditions for network cabling 
The cable can't be longer than 7 meters from the connection to the computer..
The (thicker) network cable between the 2 connection boxes is allowed up to maximum 100 meters.

What are Cross linked network cables?
Cross linked cables are used to connect 2 computers with each other without using a hub or router to connect with. These network cables are not suitable for network connections.

This applies to all types of straight network cables. Whether it's CAT4, 5, 5e or 6. Doesn't matter if it are UTP or STP cables. Cross-link cables are in most cases not work unless you have a special NIC that can switch itself (as in certain IBM notebooks). From Cat5 you can not extend the cables with coupling connectors to use patch cables.

The future: Cat7
There is a Cat7 network cable in development.

These cables would theoretically transfer data of 10GB.
These aren't yet fully developed so fiber optic cables are currently the only good solution for such data rates.
