Asian Games 2019: For India to win more medals in swimming

They train in the same city, but in different locations. Yet, during their compelling performances in the Asian Games, teenager Srihari Nataraj and Virdhawal Khade who is palpably the elder statesman of the Indian swimming team, were woven together in their pursuit of excellence by some threads like singularity of purpose, insatiable hunger to improve and relentless hard work.

They are also the flag-bearers of a sport in India which will soon find it hard to compete with other disciplines if it is not already in that position. More importantly, however, they represent different parts of the spectrum of the Indian swimming story – Khade, soon to be 27, representing what could have been and Nataraj, 17, what could possibly be.

Let us consider some facts before we take that discussion up. At the Asian Games, Indians have so far secured places in half a dozen finals, with Khade’s fourth place finish in the 50m freestyle final being the best. They also earned reserve berths in two finals and rewrote National records eight times. And, the two men in focus accounted for six records and four finals.

Virdhawal Khade’s fourth-place finish in men’s 50m freestyle is India’s best result swimming so far in the games. AFP

There have been questions, mostly from those who probably do not appreciate the standard of swimming in the continent, about the value of the National records since they did not lead to medals. A look at the medals tally in the Asian Games offers a helpful hint. Japan and China have cornered bulk of the medals.

And only five other countries claimed any medals, Singapore’s Olympic Games champion Joseph Schooling winning two gold medals from under the noses of the swimmers from the ‘Big Two’ in the 50m butterfly final in 23.61 seconds and in 100m butterfly final with a Games Record time of 51.04. Korea, Hong Kong, Kazakhstan and Vietnam figured in the charts with at least a medal.

Of course, the statistics do not augur well for India but there is hope yet. It has to be believed that the two men will have done a fair bit in raising the profile of the sport with their consistent performances at the GBK Aquatic Centre in Jakarta.

One has made it a habit of lowering the National Record each time he enters the pool – and Nataraj had already shown that he could do it in the Commonwealth Games – while the other rewrote a couple of sprint records that he set as a teenager nine years ago. They are both driven by the desire to excel at the highest of platforms – the Olympic Games in 2020.

With due respect to all those who have nurtured these champions, it is time for Swimming Federation of India (SFI) to script a professional course. Many years ago, swimming received a shot in the arm when Australian Eric Arnold coached the Indians, notably Khajan Singh. It is time that a similar boost of inspiration comes by and helps talented swimmers raise their own standards.

With Bengaluru now boasting of a world-class aquatics centre in the Padukone-Dravid Centre of Excellence, it should be possible for the Sports Authority of India (SAI) to tie up with it so that the country’s best swimmers could train there – with their own coaches and perhaps with those commissioned from overseas.

Khajan, who won the 200m butterfly bronze medal in the Asian Games in Seoul in 1986, is among those who cry themselves hoarse that India does not lack talent. Clearly, the country needs a modern high-performance plan that will ensure that the really talented youngsters – and there are a few like Advait Page and Neel Roy – are groomed to win medals at the continental level.

Perhaps, the teenagers can try and discover the NCAA route that high jumper Tejaswin Shankar has taken. Nataraj would be worried if his grades will get him to a good university or not. His timings and potential will help. Surely, India’s sports establishment can find him a solution, without his having to take a study loan to find the right environment to evolve more rapidly.

It is important that he does not go the same route as Maana Patel, the 18-year-old backstroke swimmer from Ahmedabad, who was in the TOPS list in 2016. By insisting on her remaining in the Gujarat capital, some officials stunted the chances of her growth. Worse, the 18-year-old’s injury woes have kept her away from competition for a year now – and from the Asian Games.

It is time for the SFI to wake up to the reality that the sport faces a threat from many other disciplines, especially with many states announcing lucrative rewards for medal winners in the Asian Games. There is no doubt that swimming is a visual delight, but for the sport to stay relevant, it is imperative that it invests a lot more in discovering and honing talent.

The best people in the business, including some from overseas, must come together and find a way to take the elite swimmers, especially Nataraj, to the next level. Without exception, the talented in any sport need a great deal of planning to rise and be counted at the international level. It can only be hoped that the backstroke swimmers are nurtured with care.

Else, four years later, we would be talking about missed opportunities. Again. And Nataraj may well be the Khade that we would be speaking of. In hushed and poignant tones

Importance of Accident Insurance

 

Think about a state of affairs wherever the bread winner of the family gets concerned in associate accident throughout a vacation trip. the full family would ought to face innumerable hassle when the incident, with the exception of the mental trauma. The introduction of a policy to fulfill the implications of such unforeseen things became a reality within the 1800s. although it’s ordinarily named because the accident insurance, it’s constant options as that of the incapacity financial gain that’s provided to numerous those who meet with accidents.

 

A number of people are not aware of the correct purpose of the personal accident insurance cover. It does not serve the sole purpose of providing financial support to individuals who face accidents during a trip for which they have been insured. It is a policy that completely covers all the expenses that occur due to an accident. This can be either daily or monthly payments and in case of death due to an accident, a lump sum payment can also be done. One of the most inexpensive forms is that of accidental death and dismemberment. The various insurance agencies which offer such policies differ from each other in many aspects. There are various ways to buy such an insurance coverage and each agency provides coverage to only a set of requirements.

 

The cost incurred in getting this insurance varies with respect to the needs of a person. Situations that have less chances of occurrence such as traveler’s accidental death insurance are lesser than that of injury when not at work which require a lot of medical attention. Moreover, missing work on account of such accidents would normally tend to cost more. There is a misconception that accident insurance pays for a very long period of time. It is usually paid in percentages with death getting a hundred percent payment. Increase in payment is done for certain special cases like meeting with an accident while wearing a seat belt and so on.

 

The main reason why a lot of individuals purchase this insurance policy is to supplement the already existing insurance coverage. Getting the benefits of foregone income is the most attractive aspect of this special personal accident insurance policy. You never know when you might meet with an accident and cause huge financial burden to your loved ones. In such situations, the emotional turmoil faced by people around you would be incomparable. Most of these unexpected expenses can be easily met when a personal accident insurance cover is taken.

Some Errors Made in Data Recovery

Software users usually expertise panic and frustration once the files on their machines cannot be accessed. It’s usually significantly nerve-racking for homeowners of small- and medium-sized businesses. they do not have the resources that giant corporations command, and a loss threatens to place them out of business permanently.

 

 

Data recovery services provide recovery assistance to the business owner, retrieving lost files for a fee. However, some people will try to recover the files themselves to save money. This can be done in some instances; however, if mistakes are made, the data might never be found.

 

Probably the biggest mistake is getting in a hurry, coupled with poor planning. Recovering from a data disaster recovery is usually the last thing a small-business owner plans to address. Unfortunately, it’s also one circumstance that can quickly shut their doors. When disaster strikes, they will try anything that they might have heard, often worsening the situation. The best advice is to shut off the machine, sit back calmly and formulate a plan.

 

Another mistake some people make is opening the hard drive case. They think they will discover the problem by peeking inside. Because of the delicate components in a drive, this sometimes spells doom for the data contained on the drive. This task should be entrusted to a data recovery service that maintains the proper equipment for the job.

 

When a laptop or pc won’t boot up, even when the hard drive spins up, the likely culprit is a logical failure. This often happens when system files have been corrupted or deleted. A user with a little knowledge of computer operations may try to re-create the drive’s partition. They know the data is still there; they just need to repair the system. Unfortunately, this can also lose data permanently.

 

Akin to partition re-creation, formatting the drive before the files are recovered will also result in permanent loss. Formatting overwrites all of the files on the disk. The chances of a successful recovery are slim to none.

 

Even if the user knows that recovery is performed before system repair, he may try to save the data back on the same drive, another big mistake. The area where the original files were stored may be perceived by the system as available. Therefore, the computer may write some of the recovered file over the unrecovered files, deleting them before they can be retrieved. Recovered files should always be written to alternate locations, such as an external drive or a secondary internal drive.

 

When the computer owner finally realizes that the drive should be taken to a data recovery specialist, he should always provide the recovery engineer with as much relevant information as possible. This is especially important when server recovery is needed. Servers can be designed with one of several RAID configurations, each with its own recovery procedure. Failure to provide all of the pertinent information hurts the chances for a successful recovery.

What to Do In Order to Get the Best Homeowners Insurance Possible

Even though you might not legally be required to have homeowner’s insurance (depending on your state), you will still need it. If you’re a new homeowner, your mortgage lender will most likely require coverage in order to get your loan. If you have already paid the home off, it’s still a good idea to search for best homeowners insurance rates so that you can get coverage to protect you in any case that you either lose your home or are about to lose your home, for any number of reasons (a lawsuit, fire, flood, etc.)

 

 

How do you get the best rates? By shopping around. Take a minute to search a reliable site for quotes and compare those quotes to learn about the different companies, coverage options, and policy details. Read over each offer carefully, including the fine print. Know exactly what the coverage costs, which should ideally be the home, property, and contents. Some companies may require you to purchase home contents insurance separately.

 

Do not confuse the amount you paid for the house with the costs of rebuilding it. Construction prices only ever go up, not down. The value of a house only goes down after time, unless you make significant upgrades. If your house has “disaster-resistant” features or security equipment and technology, insurance companies will likely offer a nice discount. You can do things like reinforce your roof, modernizing your electrical systems, getting an alarm system installed, etc.

 

Try your best to maintain a good credit score. If your credit is bad, it’s going to be more difficult to get the best homeowners insurance rates. Try your best to catch up with your bills and increase your credit score as quickly as you can. Prove to potential insurers that you are successfully improving your personal credit.

 

How to Get the Best Homeowners Insurance Rates

Try to obtain any discount you can. Most insurance companies offer some type of discounts to entice new homeowners and to keep current customers loyal. The types of discounts available vary from one company to the next. As mentioned above, there ARE usually discounts for having a weather-proof and burglar-proof home. However, you might also get a discount for paying annually instead of monthly, or for being a non-smoker. Some insurance companies really do offer discounts if all the people living in the home are non-smokers.

 

Get all of the information regarding your house and its construction materials prepared, as you might be required to provide a lot of details during the application process. Do you have a garage connected to the home? What kinds of materials were used to construct the roof? Be sure and answer correctly so that you can get the right insurance for your needs.

Virtualized Server Farm Challenges

Although server farm virtualization is far from being a new concept, the introduction of a Virtual Machine Monitor for servers based on Intel Architecture by VMware Inc. first, and other vendors subsequently, has made it in the last few years a very hot topic. Many firms have just started to introduce virtualization, and some have not even yet, but many others are already coping with a new set of specific issues due to virtualization. In this article we shall explore two related issues some people believe will play a significant role in the near future: VM stall and VM sprawl.

 

 

VM stall

IT departments have often decided to start the virtualization process for their server farm by focusing on servers belonging to one of the following categories:

  • Development servers.
  • Test servers.
  • Servers with low utilization rate.
  • Old servers no longer supported by the HW vendor but whose application stack is still required.
  • Unsupported operating systems (e.g., Windows NT 4.0).

This choice was grounded on several good motivations like the following:

Mitigation of the of the unsatisfactory performance risk. Excessive latency due to the virtualization layer overhead may produce unexpected performance problems whose business impact may be acceptable for development and test systems, but unacceptable for production systems. Moreover, generally speaking, the lower the current utilization, the lower the risk of having performance problems after virtualization.

 

High HW maintenance savings. Financial savings due the reduced number of physical servers are larger when the consolidation ratio is larger; that makes servers with low utilization ideal for server virtualization.

 

Mitigation of the support risk. At the beginning several SW vendors were reluctant to support their SW in a virtualized setting (actually some still are). Several IT departments decided to ignore this reluctance for development and test servers but they could not definitely do the same for production systems.

 

Over the time Virtual Machine Monitor scalability has improved and several risks play now a minor role. As a consequence it is quite natural to wonder whether the scope of the virtualized server farm can be further expanded. Some IT departments are reluctant to go along this way; a fact that has been described elsewhere with the expression VM stall and classified as an important issue that needs to be tackled. We must actually first wonder whether this is an issue. Firms are not introducing, or at least they should not introduce, virtualization for the sake of virtualization but only because virtualization delivers significant benefits with minimum risks. If not, we are no longer in the realm of serious business investment.

 

Let consider for instance the decision of whether virtualizing or not production servers. Would the benefits offset the risks? Clearly the answer to this question depends on many factors that need to be carefully examined. If you virtualize 100 low-utilized uniprocessor servers you should expect to have significant HW maintenance savings; if you virtualize two highly-utilized 8 core servers you should not; and you should expect to run the risk of having excessive latency particularly if the workload is I/O intensive.

 

We all know that there are benefits of virtualization that can make attractive to virtualize a server even though no consolidation benefit is accrued. If you put a single VM on top of a Virtual Machine Monitor you do not have any consolidation benefits, but you still have the possibility to move your VM to another server to perform HW maintenance without having to rely on the complex technologies like High Availability clustering.

 

In conclusion, an accurate analysis of business benefits, costs and risks is more and more important to assess whether further expansion of the virtualized server farm can be useful.

 

VM sprawl

While some people are worried because server farm virtualization is not progressing at a faster pace, others are worried for the opposite reason that virtualization is making much easier to deploy new operating system instances (a phenomenon described by some as VM sprawl). Indeed in the past to instantiate a new OS instance first required to go through the long process of procuring a new HW box on which to install that OS instance. With Virtual Machine Monitors everything is far faster: with just a few clicks you may have your own OS instance up and running.

 

Well, that may look wonderful but it actually paves the way to a whole new set of issues: the new OS instance has to be maintained, SW licenses have to be paid, and so on. Was that OS instance really required? And if so, who will take care of discarding it when it is no longer required? In short server farm virtualization has freed us from the issue of server sprawl but it has replaced it with the new issue of OS instances sprawl.

 

This phenomenon was expected and SW vendors are already offering products that help to put discipline in the VM instantiation process so that the VM sprawl risk is mitigated. Preventing the VM sprawl by creating a strong control process has unfortunately the side effect of reducing the flexibility introduced with virtualization. An alternative approach is to adopt a weaker control process and use regularly tools to check whether VMs are actually being used. We have decided to follow this strategy by adding new functions to our virtual servers monitoring tool ( WASFO Data Collector). If a VM has been little utilized for long time, or even worse if it has been off for long time, it may well be that nobody actually needs it any more. We can automatically collect information like VM uptime, utilization and others that provide good hints of whether the VM should be discarded.

 

Conclusions

VM stall and VM sprawl are phenomena that albeit producing opposite consequences can co-exist in a datacenter. A firm may experience VM sprawl in currently virtualized server farm (i.e., creation of useless VMs) and be reluctant to further expand the scope of that server farm by virtualizing other servers.
