Things to Do on the Internet When You’re Bored



Internet of Things (IoT) basically refers to internetworking and interconnection of computing devices, machines, objects, that are usually embedded with unique identifiers and have the ability to transfer data over a large and wide network. It is referred to as the connection of millions of physical devices via Internet usually used for collection and sharing of data. IoT primarily involves conversion of human intelligence towards digital intelligence by just merging the digital world and physical devices. The internet of things integrates the interconnection of the human culture with the digital information systems. The main concept of IoT was implemented with the arise of wireless internet that became more pervasive. The devices that we use in our day to day lives such as connected thermostats, ATM machines, wearable gadgets and even traffic lights all make up the IoT.

Why Internet of Things has become more relevant and important..?

Through IoT, all physical devices are connected with internet and hence it can be more beneficial in streaming of data used for collection & sharing of data. Some of the main reasons due to which IoT has become an important part of our developing economy are as follows:-

• Automation in transport systems:-

IoT when implemented in the transport systems especially in traffic monitoring systems has all the more improved in reducing the traffic flows, consumption of fuels, and hence will result in saving many lives.

• Education combined with IoT:-

With the advent of IoT in education sectors, it has enabled to bolster the security of the campus, enhancement of the educational institutions to manage their key resources, and also provide a better access of information to teachers, parents, and students.

The use of some automated software which mainly aim at the easy management of the entire school administration by connecting several networks to a single database server will be more efficient. This can be implemented with the help of school ERP softwares such as CampusCare which is one of the prime tool mainly used for the hi-tech education system.

• Ensures Security & Safety of Students:-

The IoT has proved itself efficient in ensuring security of students inside the campus. The RFID technology is combined with IoT to track and easily access information regarding the student’s real-time location while being on-site which is a major benefit for parents & teachers to ensure about their child’s safety. Some of the effective devices that can be used by students includes the RFID wristbands and Smart ID-cards by which their exact location can be tracked at any time.

• Cost Savings & Increased Energy Efficiency:-

Inside the school & college premises use of IoT technology can be made more efficient to the educational administrations by reducing cost of heating, air-conditioning and lighting. Smart temperature sensors can be easily installed inside the classrooms and also the industrial sectors, by connecting these sensors to heating systems to monitor the temperature conditions. Through IoT system connected to heating systems, windows will automatically open & close, turn up & down the radiators and also will control the heating systems thus ensuring a balanced & normal room temperature and no wastage of energy.

• Financial & Accounting Sectors:-

The IoT can help the school administration in case of tallying the accounts by just connecting the payment system to a central database server and then monitoring & reporting of accounts can be automatically without any manual intervention.

• Enhances student performance:-

The use of IoT in the field of education provides a student-centered approach where the wearable gadgets and muse headbands are devices used by students that can have a potential far beyond the daily routine documentation. Thus, it will help in monitoring the heart rate and brain signals and therefore benefits teachers and parents to receive alert notifications of any distracted thoughts and thus keep their children stay focused.

Along with the positive side of the use and implementation of IoT system, there are also some of the challenges faced and they are as follows:-

• Lack of Financing:-

The wearable gadgets and smart devices are sources of hi-tech technology that are not easily available at cheap rates and hence are very expensive. Hence, there needs to be a large financial support for the implementation of such devices.

• Implementation:-

One of the biggest challenges faced in the implementation of IoT is Interoperability among the smart gadgets’ manufacturers. Since the IoT connects with the small scale industries, there can be problems of compatibility where the manufacturers of small-scale industries cannot work smoothly with each other. Hence, they are at a risk where the monopoly of their market can be affected.

• Loss of Privacy and Data Security:-

Nowadays, our everyday devices are rapidly connected to the Internet and therefore there can be a threat that all confidential information regarding the user can be easily hacked by any unauthorized users. Hence, security of confidential data is not ensured to a large extent.

• Technologically controlled life:-

The use of hi-tech technologies in our daily lives has become so prominent that in the near future days we will be completely dependent on the technology and hence it will drastically reduce human interaction skills across the society.

• Lack of Menial Staff:-

The unskilled workers are the ones who are most affected by the invasion of automation in our daily lives. This can lead to large extent of unemployment which can thus be overcome by education.

The IoT has already taken a priority in our everyday lives, even without the realization by many of us. As technology is continuing to grow and develop day by day, so too will the use of IoT for many of our basic interactions. Thus the Internet of Things in the near future will revolutionize our daily lives. It is up to us on how we decide that our daily lives are willing to be controlled by hi-tech technologies. If implemented correctly, it will automatically adapt to our basic needs and thus will benefit society as a whole.

Importance Of Surveillance Technology In The Schools




The school is one of the densely populated establishments in the community. Filled with youths, it is one place where energy exudes, and where minds are sometimes full of curiosity and ideas. The young often look for adventure, especially in schools where pranks are often a part of the student’s agenda for the day. For some, they do pranks for fun, but still, it surely is not fun for the victim. Sometimes pranks by students also include vandalism or destroying school properties. It becomes a problem on the part of the administration since these dirty pranks will go on unless they find a way that would be the best deterrent against it. Finding out the perpetrator or prankster may sometimes be successful especially when there is a witness to the action. However, in some cases, they remain undiscovered. The school’s best solution to this is to make use of surveillance technology. This makes use of equipment that would record what is happening in a designated area focused by the surveillance equipment. The equipment commonly used by public establishments is a CCTV (closed circuit TV). The following reasons give the importance of surveillance technology in the school:

1. It rightly points out to the exact perpetrator of the prank, destruction, or vandal- This leads to faster and easier decision for disciplinary action on the persons involved. False accusations or blaming the innocent is not justifiable with the presence of a CCTV.

2. It serves as a deterrent for future misbehavior by prankish students- Those who are aware already of the surveillance equipment in the campus would now have second thoughts on doing their act. Prevention here is admirable as it lessens security risk also inside the campus.

3. It supports positively the security guards of the school- With this; the security personnel can concentrate more on eyeing other prime security threats in the campus. This would set at ease the school administrators and give their concentration on the student and teacher’s performances and benefits instead.

These factors on the importance of surveillance technology in the schools are of primary importance inside the schools. It will be advantageous also for the community where the school is situated. With a CCTV, for instance, the youths will have something that would remind them that there are things that society will not approve of or some actions we do would not be beneficial for everybody concerned.

Run Time Analysis in ABAP




The ABAP runtime analysis enables you to analyze the elapsed run time for individual objects such as transactions, programs, or function modules, or subobjects such as modularization units or commands. An ABAP runtime analysis is especially useful for individual objects that are CPU-intensive (see Workload Analysis).

An ABAP runtime analysis has three phases:

1. Limiting the data to be measured: In this phase, you decide which object is to be analyzed. You also decide the type of aggregation that is used (full aggregation, aggregation per calling position, no aggregation) and whether to use filter options (for modularization units or commands).

2. Measuring the data: You can measure or record the run time data either in the same user session in which the ABAP runtime analysis is running, or in a separate user session. You can also start the ABAP runtime analysis for an R/3 work process and record the run time data for an object that is being processed by that work process.

3. Analyzing the data: When using full aggregation, you analyze the data in the hit list, which provides a log record for each called modularization unit or instruction. For runtime analyses using no aggregation or aggregation per calling position, there are further hit lists, such as table hit lists or a call hierarchy.

To access the initial screen of the ABAP runtime analysis, in any R/3 screen choose System >> Utilities >> Runtime analysis >> Execute.

The runtime-analysis results are either saved to an operating system file on the current application server for up to 8 days, or transferred to the frontend. The results file can be loaded into the ABAP runtime analysis from the frontend at any time.

The R/3 System parameter abap/atrasizequota specifies how much memory should be reserved in the file system to store the results data. The R/3 System parameter abap/atrapath specifies where the results data are stored in the file system. In the field Short description, enter a short text to identify your analysis.

In the screen area In the current session, select and specify the object to be analyzed. To execute the object, choose Execute. Alternatively, you can use In a separate user session to access an R/3 work process (see slides Obtaining Run Data).

Limit the data for output:

The Program part tab lets you limit the recording of data to specific program parts. For this you must specify the program and its type (program, global class, or subprogram), and the procedure to be measured. By selecting Within and below, you extend the recording of data to include program parts and instructions within the program parts you specified.

In addition, you can limit the recorded data by choosing Specific units. This enables you to record the data between either static points, such as the ABAP instructions SET RUNTIME ANALYZER ON and SET RUNTIME ANALYZER OFF, or between dynamic points, such as the menu options Runtime analysis Switch on (Transaction code RON) or Runtime analysis Switch off (Transaction code ROFF).

Under Duration and Type, you can specify the maximum size of the results file and the maximum recording duration. Select the aggregation level. Selecting Full aggregation causes one record to be created for each program part or instruction. Selecting Aggregation per calling position causes one record to be created in the results file for each calling position. Selecting No aggregation causes a record to be written in the results file for each call.

The ABAP runtime analysis is normally used with a top-down procedure. First, record the run data for an individual object with full aggregation and identify critical program parts and instructions. Next, limit the recorded data to the critical program parts and instructions, and set the aggregation level to per calling position or no aggregation to receive more detailed information.

10 Ways to Cool a House Without Air Conditioning




Sleeping on the front porch after a hot summer day was a straight out necessity. The upstairs of the 1940’s farm house had turned into a sauna and sleeping in the upstairs bedrooms was not possible. Even after the sun went down, the upstairs seemed to get hotter. Let’s look at some ways to cool a house without air conditioning?

Now that I spend time trying to figure out how a home can be more energy efficient, I think back to those hot summer days and wonder two things:

1. Where was the air conditioner?

I have seen several articles floating around that talk about air conditioning as being an unnecessary appliance. That people have gotten soft, and if people would just handle the heat like a caveman, they wouldn’t need those energy wasting air conditioners.

Growing up in that Northwest farm house, air conditioning was not expected. Sleeping on the front porch a few times a year was. The air conditioner was only for city folks that were not lucky enough to live on a farm.

Where was the air conditioner? It was still in the Variety Store Catalog.

2. Why did the upstairs get so hot in the evening?

When you’re sleeping on the front porch and your 10 years old, you don’t really care why the upstairs is so hot. It’s not something you try to figure out before you find yourself sleeping on the porch again. You like sleeping on the porch.

If the upstairs is too hot for sleeping and you would rather not risk sleeping on the porch, or anywhere else outside, then considering why the upstairs and the whole house is so hot in the evening becomes an important issue to solve.

Air conditioners are fairly energy efficient appliances, but they’re not free to operate. With the constant grinding of the A/C and the power bill increasing by the hour, a person has a tendency to think about why the upstairs is so hot and ways to cool a house.

Years Later:

The old farm house was being moved to a new location and I had a chance to look in the attic while part of the roof was removed. Instead of the attic being the dark, spooky cave of my childhood, it was an inviting place to explore with plenty of natural light.

I was surprised to see that the attic had nothing in it. No old magazines, no old socks or toys, no old carcasses of rats or cats. Of course, there was no insulation either and I could look down the chimney chase from the attic clear to the basement. This is a good place to start to answer the question of ways to cool a house.

The roof had no attic ventilation at the roof peak or the eves. The only ventilation was provided by two gable vents, one at each end of the attic. The roof shingles were always a dark color.

I understand very well now why the upstairs of this old house was so darn hot after a hot summer day. The attic collected the heat all day and then shared it with the downstairs all evening.

How to keep the attic from overheating and ruining a good night sleep.

Here’s 10 ways to cool a house before you add air conditioning. These will help your attempt to keep the home livable in the evenings – try these retrofits and improvements.

1. Solar powered attic fan

A solar powered attic fan works very well and is a one time investment in the amount of $450 to $800. When installed on your roof, the self-contained solar unit exhausts hot air from the attic whenever the sun hits the solar array with enough bright direct sunlight to operate the fan.

Best operation occurs when attic ventilation is added along the eve’s and the roof peak ventilation is limited.

2. Roof sprinkler system

Well, it works on flat commercial buildings, might work on homes too. Anything that will cool the roof surface will help keep heat from radiating into the attic space. Unfortunately, this may increase your water bill substantially. Sprinkler and hose, $20. Water bill around $300.

3. Really big trees

Shade the roof and you have a cooler attic and a cooler home. If you have a two story home and you’re just getting around to planting shade trees, this solution may take a while to materialize. One redwood tree 12 inches tall, $4.95. Expect shade in 40 years.

4. Air sealing the attic floor

Especially before adding insulation – don’t add insulation to the attic floor without air sealing the air holes and penetrations first. Best process, good drop light, knee pads, and a can of Great Stuff spray foam insulation. Material cost, $30.

5. Adding Additional roof ventilation

Ways to cool a house starts with attic ventilation. Most older homes simply do not have enough attic ventilation. Ventilation should allow air flow from the eve’s to the peak. Take out solid bird blocking and add screened vents at the eve’s. Add manufactured metal or plastic roof vents near the peak. During the installation of new roofing is the best time to add attic ventilation. Eve Soffit vents, $8.50. Roof peak vents about $12

6. Adding insulation

After air sealing, install insulation. Insulation will help slow the transfer of heat from the attic to the living space below. The more insulation the merrier. Building codes keep adding insulation, in some of the colder parts of the country, insulating to R-49 is code. That’s about 16 inches of insulation.

Don’t worry, this could be a do-it-yourself project. The big building supply stores have the material and the equipment you need to do the job.

Add insulation in the colder climates to keep warm, add insulation in the warmer climates to keep cool. Add 12 inches of blown fiberglass insulation for about $1.25 to $1.75 a square foot of attic floor space.

7. Sealing the knee wall floor connection.

Many older, two story homes have knee wall attic space. This is the space along the walls of an upstairs room that has reduced headroom along the sides of the room. You know, your standing upstairs and you must be careful to stand in the middle of the room to keep from bumping your head.

The problem is the knee wall attic is often open to the space between the floor of the upstairs room and the ceiling of the downstairs room. This means the hot air in the knee wall attic can travel right under the upstairs floor and help heat the whole house.

Stuff some insulation in a plastic bag and stuff a bag between every floor joist opening in the knee wall attic. This will keep the hot air from traveling between the floor and ceiling. Sealing these floor joist openings is important during the cooling season and the heating season. Plastic bags $.50, insulation, $1.00 a bag.

8. Sealing chimney chase

In older balloon framed homes, the chimney chase is often open and allows heat and cold transfer between all floors, clear from the attic to the basement. For effective cooling and heating, these chase corridors should be sealed off. Spray foam insulation, $7.00 a can.

9. Place Fans in Upstairs Windows

Place one or more big box fans in upstairs windows. Install them so they are blowing out the window. Close all other windows and exterior doors but leave the interior doors open all the way to the basement. Draw the cooler basement air up through the house and out the upstairs windows.

Basements are always cooler and can help cool the rest of the home. Hopefully, you don’t have a smelly tank of stove oil in the basement! A good box fan about $30.

10. Install solar panels

Usually when you install solar panels on a roof, the panels are placed on a racking system that holds the panels off the roof about 3 inches. The panels keep the suns rays from hitting the roof surface and slow heat transfer to the attic space.

One of the advantages of solar panels on a hot day is the shading they provide the roof. Maybe not as good for shade as a big redwood, but it’s still shade.

Most power companies will help you install solar panels. They know that when the weather gets hot and all those air conditioners start up, they need all the help they can get with ways to cool a house.

Wish I still had that old farmhouse with the big front porch and the big yard. I would have a few tricks ready for those hot summer evenings when the upstairs got so darn hot. After air sealing and insulating the attic, I would install a solar attic fan, mount some solar panels on the roof, place a couple box fans in the upstairs windows and roll out my sleeping bag on the front porch.

These are ways to cool a house, but you can still get a good night sleep on the front porch. Of course, these days it would take a better air mattress than it used to.

Thank you for stopping by, hope you will sleep a little cooler tonight, don’t forget to turn the light out…
