Perangkat lunak ArcView sudah tidak dikembangkan lagi oleh ESRI dan untuk selanjutnya digantikan oleh ArcGIS sebagai penerusnya. Namun masih banyak praktisi Sistem Informasi Geografis yang masih menggunakan ArcView , salah satuny adalah ArcView 3.3, sebagai perangkat lunak utama dalam pekerjaan spasialnya. Kendala muncul seiring dengan perkembangan sistem operasi Windows yang telah sampai pada Windows 7. Banyak orang mulai beralih menggunakan Windows 7 sebagai sistem operasi utama pada perangkat komputernya.

Kendala muncul ketika banyak praktisi SIG yang berusaha melakukan instalasi ArcView 3.3 ada Windows 7. Proses instalasi ArcView GIS 3.3 terkadang berhasil diinstal namun tidak dapat dijalankan atau bahkan proses instalasi tidak dapat berjalan sama sekali. Hal ini mungkin disebabkan tidak sesuainya program Arcview 3.3 dengan Windows 7. Namun permasalahan tersebut bukanlah tanpa pemecahan sama sekali. Kita tetap dapat melakukan instalasi ArcView GIS 3.3 pada Windows 7 dengan langkah-langkah yang akan diuraikan dibawah ini.

Tips Studio Spasial - Windows 7 memang bukan operating system baru, namun bagi praktisi Sistem Informasi Geografis (SIG) saya yakin masih banyak yang menemui kesulitan ketika menggunakan sistem operasi windows 7 sebagai sistem operasi dasar dalam PC atau laptopnya. Banyak kendala ketika kita melakukan instalasi program-program GIS maupun ekstensi-ektensi program SIG yang bertebaran diluar sana. Misalnya ketika melakukan instalasi ArcGIS 9.3 dan update ArcGIS 9.3.1, instalasi XTools Pro 5.2, atau instalasi ERDAS 9.2.

Berikut ini adalah salah satu contoh error saat instalasi ekstensi ArcGIS XTools Pro 5.2 : Microsoft.VC80.OpenMP,type=”win32″,version=”8.0.50727.762″,publicKey Token=”1fc8b3b9a1e18e3b”,processorArchitecture=”x86″‘. Please refer to Help and Support for more information. HRESULT: 0×800736FD. assembly interface: IAssemblyCacheItem, function: Commit, component: {1E507087-0819-45E0-A01F-C8B3B9A1E18E}

Setelah diperhatikan dan browsing sana-sini ternyata OS Windows 7 memiliki limit / pembatasan penulisan registry. Sehingga ketika kita melakukan instalasi sebuah program yang melakukan update atau penulisan registry melebihi jumlah yang diperbolehkan dalam setting registry maka instalasi program akan gagal. Untuk mengatasi Registry Size Limit tersebut maka dapat kita lakukan langkah berikut ini, namun sebelumnya uninstall terlebih dahulu program yang gagal anda instal :

1. Buka window perintah Run dari Start > All Programs > Accesories > Run. Window perintah Run dapat diakses juga dengan kombinasi Tombol Keyboard Windows + R.
2. Ketik Regedit untuk membuka Registry Editor.
3. Pilih Yes jika ada pertanyaan UAC (User Account Control).
4. Pilih HKEY_LOCAL_MACHINE.
5. Pilih System.
6. Pilih CurrentControlSet.
7. Pilih Control.
8. Double Klik pada RegistrySizeLimit. Secara default nilainya adalah 5d00000 atau 97517568.
9. Isi dengan angka yang lebih besar seperti ffffffff atau 4250967296
10. Klik Ok.
11. Restart komputer.
12. Instal kembali program yang anda diperlukan.

Menggunakan langkah diatas maka masalah Registry Size Limit pada windows 7 sudah dapat teratasi.

The workshop is a great place for reusing items formally destined for the landfill. Even if you do not have a shop or craft area you can always donate the items mentioned in the following paragraphs to friends, schools, shops, youth center. The concept of reusing is as limitless as your imagination.

Screws, bolts, picture hooks, plant hangers, curtain hooks, and hinges are common hardware items used in most homes. Although not overly costly when purchased a few pieces at a time, they can add up over the years. Salvage any reusable hardware and parts from old cabinets, furniture or mechanical items before discarding. These can easily be organized and stored in plastic containers of different sizes. Shop with this in mind and purchase items like peanut butter or mayonnaise in clear plastic containers. These are our favorite as they are recyclable, sturdy and you can easily determine the jar’s contents at a glance. When buying screws and bolts avoid the small plastic packages and try to find a store that sells these items out of bulk bins. You save money and packaging too.

Strong plastic jugs from juice, milk, or detergents make excellent storage containers for tools, rags or parts in the workshop. At a section near the top of the jug remove all but a flap of plastic to attach it to a wall or post. Any rough spots can be filed off or covered with tape. Drill a few holes in the bottom for drainage and use in the same way outside in the garden and for storing clothespins.

Any clothing or towels too ragged to donate to a thrift store still have value. Cut the material into squares of different sizes to use as cleanup rags. Many garages, cabinet shops and backyard mechanics will gratefully accept excess rags. Sewing groups would gladly accept the buttons and zippers gleaned from the clothing. Children’s programs and daycare centers also use buttons for crafts.

Small household appliances that are no longer working can be salvaged for parts. If you are not familiar with this type of operation don’t attempt it - you can always donate them to handymen types that you may know, or appliance repair classes in your community. Handles from pots and pans can come in handy for fashioning custom tools, or they can be used to make a storage box easy to carry. Old utensils can be bent and made into various picks and scrapers.

The workshop can become a veritable stew pot of reuse ideas. As it is not a place commonly viewed by guests or neighbors it will not matter so much if the look is compromised by the reused items. Of course, the most important thing is the fact that you are reducing your landfill contribution by taking the matter into your own hands and making a difference!

Care for the environment? Want to save the planet? Then you must think in terms of fuel efficiency, non-polluting, and eco-friendly transport. The answer lies in purchasing and using a hybrid car. They not just make a statement that I care but are compact and fuel efficient.

Here are some insights that may just tempt you to buy a hybrid.

1. Made of lightweight materials hybrids are small in size. The engine is designed to be fuel efficient. When the car halts at a signal, the engine will automatically shut down and restart when the car shifts into gear.
2. These cars have the advantage of being powered by a gasoline engine and an electric motor that takes care of acceleration.
3. The batteries of the electric motor recharge automatically by harnessing the kinetic energy produced during braking.
4. Hybrid car engines produce less emission, give better mileage, idle less, and are fuel efficient.
5. The aerodynamic design reduces drag and the tires are made of a special rubber that reduces friction.
6. The battery has high capacity and is made of nickel-metal-hydride. The battery can run the hybrid when called for.
7. The power-train technology enables using two power sources and enhances fuel efficacy.
8. There are many choices. You can have a hybrid from Honda, Ford, Toyota, GMC, and Chevrolet.
9. If your transportation of choice is a hybrid then the US Government will applaud your choice by giving you significant tax breaks.
10. Using a hybrid means you are active in ensuring the air is clean and that you are a concerned citizen who wishes to save fuel which is precious.

Maximize usage by “pulse and glide.” This means finding the ideal point where electric and gas energy are equally utilized. Generally this ideal lies between 30-40 miles per hour. Stabilization of energy is learnt by practice it really cannot be taught. Another important aspect is that you benefit if you don’t rush around and drive at the prescribed speed limit. If you glide, instead of accelerate then you can make a saving of as much as 10 cents a gallon. Lastly check and maintain tire pressures. This will help lengthen the life of the tires and help you save fuel. Reduced tire pressure studies indicate reduces gas mileage by as much as 10%.

Before you say “yes” to buying a hybrid car, you must do in depth research on hybrids, the pros and cons. Talk to manufacturers and owners. Test drive the different makes and check which one would suit your life-style. Some hybrids are ideal for city driving while others are more efficient on open roads.

Even if the buying price is steep the fuel that you save along with incentives like tax breaks make a hybrid a good and sensible choice.

Hi-tech ways to capture enough sunlight per day every day to power everything in a home or business hasn't been discovered yet. The current cost of solar panels can run into thousands of pounds, which would require the panels to produce electricity for years without maintenance in order to see a return on investment.

Many people use solar panels, which can be placed on a side of a roof to attract sunlight during the day to heat a small number of rooms and water. Solar panels can be purchased at a number of locations throughout the UK, as well as online. Panels do a great job of helping families and businesses to conserve energy. Hopefully, solar panels will become a part of daily life, in order to prevent the disappearance of natural resources and to maintain energy conservation. In the recent 2006 Budget announcement by Gordon Brown, millions of pounds have been allocated to helping homes and businesses take advantage of renewable energy and the benefits that it brings. This is a welcoming strategy by the government. More and more homes are also attaching mini-wind turbines to their homes to boost the electricity generated by solar panels, British Gas (Centrica) have recently been looking for volunteers to pilot this with.

Developing countries with sunny climates such as Africa are the perfect place to take advantage of this renewable energy especially in rural areas that are not connected to the national grid for electricity. There needs to be a commitment from the G8 and other government around the world in providing funds to achieve this.
