Why Do they Hack?

We would be generalizing too much if we were to put all illegal and unethical computer users into the same category. Motives and goals vary too much. Some online activities are aimed at stealing money or merchandise; some online activities will pirate software (especially games) without affecting the original. More than a few illegal online activates are undertaken by thrill seekers, who do not intend any harm be may cause problems simply by ‘trespassing’. Then there are also a few honest ‘white hat’ individuals who hack in order to report inherent weaknesses to those in authority.

The motives and goals for criminal hacking it both complex and obvious. In the end a criminal hacker want to steal. The psychology that lead to this desire is complex, yet unimportant for the victim. The obvious goal is theft of property and money, and the obvious solution to this is better security.

Piracy, the illegal copying of something such a software or film, is not the same as stealing an object, but it is still illegal. The mindset behind this is probably not as corrupt as a hardened criminal. The individual wants something without paying for it, yet would almost certainly not steal in a direct manner. They might copy a music recording, but they would never steal a CD from a retail shop. The original owners of the copied material are losing potential revenue from this, but the actual loss is hard to calculate. Often those pirating the material would not be willing to pay for it, so there was no real potential sale. Yet this remains unethical as the efforts of those creating the material are not rewarded.

Many hackers will break in to the security of the system merely for the thrill. This is a form of rebellion, and it has some psychological roots in belongs to a social group while being rejected by society as a whole. Early 1980s hacking seems to have been done primarily by teenagers, who eluded authorities for a time. Like most teenage rebellion this was a stage they ultimately outgrew.

Hackers often see their activates as ‘art’, and ignore the (perhaps serious) criminal aspects or their endeavours. Yet despite their motive and intentions they run the risk of causing serious damage to important computer systems. Software and hardware security measures must be used to prevent this damage. There are companies such as Supremanic providing top quality finger print scanning system.

Physical security, protecting the company building, never goes out of style. If fact it tends to have a significant influence on computer and internet security. Fingerprint recognition has used by many high end security installation for many years. It has now started to become commonplace for midrange smartphones. Hacker, for all their ingenuity, will always have a difficult time with fingerprint recognition.

Generation Changes in Air Travel

Air travel changes with technology, social situations and politics. Since a generation ago there have been many changes.

Jet Lag

The world is still the same size, but technology has compensated to changing time zones in a few ways. Just having a better flight condition, so we don’t get dehydrated, so we might get some sleep, makes all the difference when we arrive. Carbon fibre components in aircraft help this situation considerably.

Cost

In the 1980s it cost the average person three weeks wages to fly to the USE or UK. Now it is about one week’s wage.

Booking Online

It is much more convenient to book with the internet than it ever was to use a travel agent or book over the phone. This reduces the cost as we are not paying for an individual to serve us. Sydney airport transfers are easily made on the internet.

Book an airport shuttle Sydney wide on the net, and save time and money.

Security
Much more strict that a generation ago. Who would have thought there would ever be a restriction on bringing liquids on board?

At the same time the security checks are actually quicker than before. And baggage weight allowances have increased.

Entertainment

In the 1990s everybody in the plane watch the same film(s). Now it is common for each seat to have its own screen and a wide choice of films. It is also becoming increasingly common to use Wi-Fi on a plane.

Politics of the Destination

US President Trump has tried to set limitations on travel from some countries. This was hardly an issue in the 1990s. Though most of these proposed restrictions have not been upheld.

Dress Regulations

Long ago people dressed up when they took a plane trip. After plane travel became commonplace they started to dress for comfort, and in anticipation for the weather at their destination. We have tended to become neatly casual when dressing for aircraft, and do not have high expectations of others.

In early 2017 a pair of teenagers were turned away from a flight because of inappropriate attire. Many people were surprised by this, and surprised that airlines still had dress regulations. What is underreported is that the two teenagers were flying on an employee pass, so were considered to be representatives of the airline; restrictions are more severe and more likely to be reinforced in these situations.

Most airlines do have dress codes, but they are fairly tolerant when it comes to reinforcing them. As long as passengers are reasonably attired there is nothing said.

Dress for you destination. 

Safety

There are more flight and airlines than ever before, yet accidents are becoming even less common.

Sydney Airport Shuttle Services

A Sydney Airport Shuttle is always a good way to start or return from a trip, no matter your attire or expectations. Let your vacation or business trip start the moment you leave your home.

TIGER PAINTING – ROOFS

Painting Services Sydney – Roof Painting

The material and colour of house’s roof affect the inside temperature. Some materials conduct or insulate heat, and some colours will absorb more heat than others. Darker colours, especially black, absorbs the most heat and raise the temperature inside the house. Repainting the roof in a different colour can lower the temperature inside the house, thereby reducing the summer electricity bill.

 

Research over the last generation has discovered that groups of suburban houses subjected to the Sun can create Heat islands. A Heat Island is basically an area that absorbs and retains more heat than an otherwise unoccupied area. The roofs of many houses absorb the Sun’s rays and keep the local outside temperature 1-3 Degrees warmer in the day, and up to 12 degrees warmer at night. This has a bad environmental effect, if only because of the raised air conditioning bills.

Appropriate Colours for House Painting Sydney

Australia is divided into 8 climate zones, with 69 subzone divisions. The Australian Building Codes Board (ABCB) advises on the most suitable materials and colours for roofing in each of these areas. Following these guidelines will reduce energy expenditure and electricity costs in private housing.

 

Installing solar panels on the roof of a house will mean the sun’s energy is put to good use. Electricity from solar panels can be used to cool (or heat, if necessary) the inside of a house, more than compensating for the heat of the Sun.

 

House Painting Services Sydney

For House Painters Sydney is a fairly stable situation. While there are seasonal fluctuations Sydney residents do not have to tolerate extreme conditions like snow or tropical storms. One roof material and colour does quite well for the entire year.

Talk to your painters about the right look for you house, and the best way to keep temperatures stable. The benefits are long lasting.

DENTAL SEALANTS

Dental Sealants significantly reduce decay problems in the back of the mouth.

Our back teeth have an uneven upper surface. This surface, which is used for chewing, tends to accumulate debris. This can lead to problems with decay, especially if there are small pits and fissures in the tooth. Dental sealants are an invisible coating applied to the upper surface of the molar teeth. This sealant fills in any gaps, pits, fissures or unevenness in the tooth surface, prevent problems with accumulating debris. This keeps teeth cleaner and healthier.

Children who have dental sealants applied to their back teeth have significantly lower decay problems. Cavities are reduce by 60% to 80%. This saves both the teeth and considerable money in the long term.

Modern sealants are either resin or glass ionomer based. They usually last four years, but some have reportedly lasted nine years before they needed replacement.

Wisdom Teeth Dundas

If the mouth is kept in good health there are fewer problems later in life. Wisdom teeth are one of the few exceptions to this. There is often insufficient room in the mouth for wisdom teeth to emerge properly.  Nonetheless a healthy mouth will lessen in problems that develop here.

Invisalign Dundas

Invisalign is a method of straightening teeth. It will effectively treat minor and moderate alignment problems, and has an advantage in being far less noticeable than braces. Both traditional braces and Invisalign benefit from a mouth that is free from any other issues.

Implant Dundas

Implants consist of an artificial tooth attached to the jaw with a titanium post. They are an idea method of replacing a lost tooth. Optimal dental health will reduce the need for dental implants. Keeping natural teeth is always the best option.

 

Sealants are not a permanent solution. But they will protect a child’s teeth for several years, after which time the child is in a better position to look after their mouth.

 

Flight Advice

A few flight attendants, pilots, shuttle drivers and those who fly frequently offer some experience based advice.

  • Don’t take shoes, off, or at least walk around the plane without them. You don’t know what other travellers have been walking through.
  • Planes are periodically cleaned, but the other passengers (and yourself) could be bringing anything into the plane. Treat all surfaces as unclean.
  • The special meals, kosher, gluten free …etc. Are almost always prepared just before the flight. And they are often the first served, if you find being first an advantage.
  • Food tastes different on a plane because of the low pressure, noise and the fact that the meal must be pre-prepared. Some airlines compensate by including more salt. Avoid eating too much of the airline food.
  • Know the emergency procedure. We never know how we will react in a crisis, or how others react. It helps if we can follow a procedure in a reflex manner.
  • The water on the planes is of dubious quality; this includes the tea and coffee. Bring an empty bottle and fill it up at the airport before leaving. Do drink water, because the flight will dehydrate you, but make sure it is clean.
  • Avoid carbonated drinks – the low air pressure and the bubbly drink will make you feel bloated.
  • Caffeine and alcohol will dehydrate you, more so in the dry plane conditions.
  • You are exposed to UV light through the cabin window, much like a sunny day. Wear sunscreen or draw the shades.
  • Do some leg exercises to help you circulation. The socks that prevent deep vein thrombosis are good if you travel frequently.
  • There are dress codes, but they are rarely enforces. As long as you are neat and tidy, and not showing flesh, there is very rarely an issue. The exception is if you are on an employee pass, where you are representing the company and are expected to look the part.
  • Find a way to adapt to your destination’s time zone ahead of time.
  • An old trick, but chewing gum or a throat lozenge makes it easier for your ears to re-pressurize during accent and decent.
  • Many airlines are looking at changing all flight entertainment so they it relies on Wi-Fi. If you don’t have a Wi-Fi device you will have little to do.
  • An airport shuttle solves almost all baggage and transport issues. Pre-book an airport shuttle and avoid the hassle and logistic planning at the beginning and end of you trip.

501 of the Migration Act

In December 2014 there were changes made to section 501 of the Migration Act. Now an individual’s Visa can be cancelled if they have spent 12 months in jail or if they fail a ‘character test’. This has taken many foreign individuals by surprise. In 2016 more than 1000 visas were revoked.

Before the changes to section 501 were made there were occasional enquiries made by foreigners concerned about the future of their visa status, about one per month. Now there are about two calls per day.

 

There are many more individuals on visas who do not any enquiries because they are unaware of any issues. Some people have been in the country so long that they consider themselves citizens. But legally they belong to another country, and could be deported if they have substantial criminal history.

 

There is sometime ground for appeal in these cases; if people with Australian born children, for example. But in many cases they do not have the financial resources to appeal. If their visa is revoked they will be denied legal aid, and they often cannot afford a lawyer.

 

Several New Zealanders have had their visa revoked, often while serving time in prison. They are not told of the deportation till the prison sentence is over. About 100 New Zealanders were deported for criminal offences in the 12 months following the policy change.

 

About 2,358 non-citizens have had their visas cancelled since December 2104

Avoid Common Brushing Mistakes

  • Reusing the same toothbrush for too long. A recent internet hack has been to restore the toothbrush with boiling water, but this resorted brush doesn’t last very long.
  • Our tooth enamel is slightly softer after many meals; if we brush straight away we risk damaging the teeth. Gargle with water, and brush 30 minutes later.
  • Clean the tongue as well. This harbours bacteria and causes problems like bad breath.
  • Use a toothpaste with fluoride, or have some fluoride on your teeth with a mouthguard.
  • Hard bristles and hard brushing damage the teeth. Use a soft bristle brush and be persistent but gentle.
  • We don’t need that much tooth paste. Brush more often, but with less paste.
  • It makes all the difference as about 30% of the tooth area is between the teeth’ easily the most common place for debris to get caught.
  • Missing any section of the teeth. They are all prone to problems, and they all need cleaning.
  • Brush two to three times a day. Any more than this might be too often.
  • Clean the brush with hot water after use.
  • Always store the toothbrush with the bristles facing upward, so the moisture can drain away.
  • Keep the toothbrush away for any source of air pollution, like a toilet.
  • Ignoring any pain in the mouth is an issue.

Brushing prevents most dental issues, but not all. Teeth cannot be straightened by brushing, and wisdom teeth can will cause problems no matter what we do, often requiring extraction. But keeping our teeth clean will benefit the procedures that rectify crooked teeth and problems with partly emerged wisdom teeth.
