Decreasing Boot Time

Microsoft has made available a program to analyze and decrease the time it takes to boot to WindowsXP

The program is called BootVis

Uncompress the file.

Run BOOTVIS.EXE

For a starting point, run Trace / Next Boot + Driver Delays

This will reboot your computer and provide a benchmark

After the reboot, BootVis will take a minute or two to show graphs of your system startup.

Note how much time it takes for your system to load (click on the red vertical line)

Then run Trace / Optimize System

Re-Run the Next Boot + Drive Delays

Note how much the time has decreased

Mine went from approximately 33 to 25 seconds.

Digital Camera Guide

Digital Camera Guide

By Hadi Yanuar   21.09   Tidak ada komentar:

So, it's time for a digital camera huh? Well, buying one can be more than a little difficult. What types of features should you look for? Well, this guide will tell you that plus get you a little more familiar with what these cameras are capable of.

Megapixels

When it comes to megapixels, the more the better. I recommend a minimum of 2, but 3 or 4 is great. We did a test to see if a camera with 2.3 megapixels (actually 1.92 - 1600 x 1200) could produce a good quality 8x10.

Turns out it can, if you have the right paper and printer. We used HP Premium Plus photo paper with an HP 970 series printer and made a fantastic 8 x 10. Remember, I was a professional photographer before I got into computing, so I know a good print when I see it :-)

The resolution at 8x10 (we had to crop in to make the picture proportional to 8x10) was only 150 DPI. Most printers would not make a real good 8x10 at that resolution, but this one did. So, if you want to be sure you can get good 8 x 10s, you may want to go with a 3 megapixel camera or better (that gives you around 200 DPI at 8x10 size, still not quite the optimum 300 DPI, but it looks good with the right printer).

Optical vs Digital Zoom

You've probably noticed that most digital cameras have both a specification for digital and optical zoom. Pay the most attention to the optical zoom.

The optical zoom magnifies (zooms in) using glass. The digital zoom basically crops out the edge of the picture to make the subject appear closer, causing you to lose resolution or to get an interpolated resolution (i.e. the camera adds pixels). Neither of which help image quality.

Finally, make sure you get enough (optical) zoom. A 2x zoom isn't going to do much for you. A 3x is the average you'll find in most digital cameras will probably be good for most uses. More on lenses later.

Connection

How does the camera connect to your computer? If you have a USB port in your computer, you'll want a camera that can connect via USB as opposed to a slow serial connection.

On the other hand, if your computer doesn't have a USB port, is there a serial connector available for the camera you're looking at? If so, is it a special order and how long does it take to get it?

Storage

What does the camera use to store images with? If it uses a memory stick, make sure you consider buying additional sticks when you get your camera. A typical 8 meg memory stick that comes with a 2 megapixel camera only holds 5 or 6 images at the camera's best quality.

Some cameras use a 3.5 inch disk for storage. Be careful of these!

Although it may sound like a good idea, a 3 megapixel camera at high resolution produces a 1 meg file (compressed!). That's only 1 picture per disk.

Here's a few more things to look out for when trying to make your digital camera purchase.

Picture Formats

When you're trying to decide on which digital camera to get, check and see how many different picture formats it supports.

You want something that can produce both uncompressed (usually TIFF) and compressed (usually JPEG) images. I personally use the high quality JPEG setting on my camera for most of my shooting. TIFFs are just too big and the difference in quality is not ascertainable by mere mortals.

You also want to be able to shoot at a lower resolution than the camera's maximum. That way, If you're running short on memory, you can squeeze a few more shots on your memory stick.

Auxiliary Lens / Flash

This was a biggie for me. While a 3x zoom may work for the "average" user, I needed something that allowed me to do some wide angle work as well as have a good telephoto lens.

So, the camera I purchased a few months back was a Nikon Coolpix 990 (note that this isn't the only camera that can accept lenses). It has auxiliary lenses that screw into the filter ring on the front of the lens. I now have an ultra-wide fisheye lens plus a nice telephoto.

In addition to lenses, I wanted a good flash. The flash that is built into most of these cameras gives you a top range of 15-20 feet - at best. I wanted a camera that could take a powerful auxiliary flash (again, the Nikon isn't the only camera that fits this requirement, but I liked it better than the rest). If you need more reach than the small built in flash can deliver, then make sure you can attach an external flash to any camera you consider.

As an added bonus, if you get a camera that can take an external flash, you can place that flash on a bracket and eliminate red-eye.

Flash Distance

Speaking of flashes, make sure you check the distance the built in flash is good for. You don't want a camera with a wimpy flash that only travels a few feet (well, unless you can get an external flash for it as described above).

Battery Type

This may not sound important, but it is. Anyone who owns a digital camera can tell you they eat batteries the way a sumo wrestler eats at a buffet.

Make sure the camera can run on regular (or rechargeable) "AA" type batteries. You don't want a camera that eats through expensive lithium batteries every 10 shots or so.

One thing to remember about digital cameras, they do eat through batteries. I recommend getting some Nickel Metal Hydride rechargeable for it. I have some for mine and they have saved me a fortune.

Final Notes

Choosing a digital camera isn't easy. There's a huge selection out there and only you can determine which features you need.

For instance, if you shoot wildlife photos, a small 3x zoom probably isn't going to cut it (unless you can attach auxiliary lenses to it). If you shoot lots of close-ups, make sure the camera has some sort of macro capability. If you shoot big group photos indoors, an external flash may be necessary.

My advice is to make a list of things you want to be able to do with the camera then go to somewhere that can help you make a good purchase decision.

Finally, buy the BEST camera you can possibly afford. Or wait until the price drops on one with the type of features you want.

Converting to NTFS

Converting to NTFS

By Hadi Yanuar   21.03   Tidak ada komentar:

Your hard drive must be formatted with a file system such as FAT, FAT32 or NTFS so that Windows can be installed on to it. This system determines how files are named, organised and stored on the drive. If you’re not using it already, NTFS (New Technology File System) is recommended for Windows XP because of the additional functionality it offers. If your PC came with Windows XP pre-installed then there’s a chance that you’re already using NTFS. If you’ve upgraded from Windows 98 or Windows Me you may still be using FAT or FAT 32. The option to change over to NTFS would have been available during the upgrade process. Don’t worry if you skipped this as it’s possible to convert at any time from within Windows XP without losing any data.

The recommended option

There are a number of features in Windows XP that will only work if the NTFS file system is present, which is why it’s suggested you make use of it. File and folder permissions, encryption and privacy options are just some of those you’ll be able to access. In particular, those of you who have set up user accounts will find NTFS invaluable. For instance, if you continue to use FAT or FAT32 anyone with physical access to the drive will be able to access the files and folders that are stored there. However, with NTFS you’ll be able to use a level of encryption (Professional Edition only) that will enable you to protect your data.

You’ll also find NTFS more reliable in that it’s more able to recover from disk errors than its FAT or FAT32 counterparts. A log of all disk activity is kept so should a crash occur, Windows XP can use this information to repair the file system when your PC boots up again. To find out what file system you’re using, open My Computer, right-click your main hard drive and choose Properties. Take a look at the General tab to see confirmation of the file system that’s in use.

Convert now

You can use the convert tool in Windows XP to change the file system on your hard disk from FAT or FAT32 to NTFS. The whole process is safe and your existing data won’t be destroyed. To begin, click Start -> Run, type cmd and press [Return]. At the command prompt type convert c: /fs:ntfs and press [Return] (where ‘c’ is the letter of the drive you’re converting). When you try and run the convert utility, it’s likely that Windows XP will be using your paging file so the process won’t be completed immediately. Therefore, you’ll see a brief message on screen informing you that the conversion will take place instead the next time Windows starts up. Having restarted, the Check Disk utility will run, the conversion will be performed automatically and you may find that your PC will reboot twice more.

The benefits

With your drive now running NTFS, it’s time to take advantage of the new options that are available. Having created a number of different user accounts you can now control the level of access that’s granted to individual users. For example, there are going to be certain files and folders that you’ll want some users to be able to access but not others. If you have Windows XP Professional Edition you can do this immediately.

Right-click any file or folder, choose Properties and select the Security tab. A dialog will be displayed showing the names of all your users. Alongside will be two columns which enable you to select levels of access for each of them, the permissions include Full Control, Modify, Read and Write. You can then check the appropriate box to determine whether or not to Allow or Deny a particular permission. For Windows XP Home Edition users, the Security tab won’t be immediately available. To access this option you’ll need to restart your PC, pressing [F8] until a menu appears. Next select Safe Mode and wait for Windows XP to start up. You can then set your options in the same way.

Another feature is NTFS compression. It’s quick and seamless as your file or folder is decompressed automatically when you access it. (Don’t confuse this with a Zip compression utility where the files need to be extracted before they can be accessed.) Although you may have used NTFS compression on a file or folder, there’s no way of telling just by looking at it. To remedy this, open My Computer, click Tools -> Folder Options and select the View tab. Under Advanced settings, scroll down and check the option ‘Show encrypted or compressed NTFS files in color’, then click Apply and OK. Take a look at your compressed items in My Computer and you’ll see the text label has changed from black to blue. Something else that’s exclusive to Professional Edition users is the Encrypting File System (EFS). You can use this to protect your important data so that no one else can read it. Your encrypted files and folders will only be accessible when you have logged into your user account successfully.

Computer Maintenance

Computer Maintenance

By Hadi Yanuar   20.58   Tidak ada komentar:

You may not realize it, but your computer and your car have something in common: they both need regular maintenance. No, you don't need to change your computer's oil. But you should be updating your software, keeping your antivirus subscription up to date, and checking for spyware. Read on to learn what you can do to help improve your computer's security.

Getting started

Here are some basics maintenance tasks you can do today to start improving your computer's security. Be sure you make these part of your ongoing maintenance as well.

* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.

* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.

* Install software updates immediately.

When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.)

An ounce of prevention

A few simple steps will help you keep your files safe and clean.

* Step 1: Update your software

* Step 2: Backup your files

* Step 3: Use antivirus software and keep it updated

* Step 4: Change your passwords

Developing ongoing maintenance practices

Now that you've done some ground work, it's time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.

* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.

* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program's user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk

.

* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords

.

Making a schedule

One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular "appointment" with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.

Harga Bitcoin Anjlok. Mungkin ini Penyebabnya?

Harga Bitcoin Anjlok. Mungkin ini Penyebabnya?

By Hadi Yanuar   11.52   Tidak ada komentar:

Pada tanggal 5 Januari 2015, pasar jual beli Bitcoin terbesar kedua di dunia bernama Bitstamp, terpaksa menutup situsnya dan meminta semua member untuk berhenti melakukan deposit ke wallet mereka. Trade exchange yang volume perdagangannya mencapai 15.000 Bitcoin dalam sehari itu menyatakan bahwa BitStamp telah kehilangan kurang lebih 19.000 Bitcoin (atau seharga 5,1 juta dollar AS pada saat itu). Hingga saat ini, belum diketahui pasti apa atau siapa penyebab lenyapnya sejumlah Bitcoin tersebut.
Pembobolan dalam sistem keamanan BitStamp ini membuat orang-orang teringat tentang apa yang terjadi di Mt.Gox. Harga Bitcoin anjlok sebanyak $200 dalam sehari karena ada 744.000 Bitcoin yang hilang akibat kesalahan manajemen di Mt.Gox. Tanpa ganti rugi, Mt.Gox bangkrut dan rasa percaya publik akan Bitcoin mulai melemah. Keadaan ini menyebabkan harga Bitcoin
terus menurun dari yang awalnya $800 menjadi $150 per Bitcoin. Kasus serupa terulang kembali di Bitstamp ketika pasar tersebut menutup situsnya secara mendadak. Disitulah saatnya komunitas Bitcoin mulai bertanya, “Apakah BitStamp akan berakhir seperti Mt. Gox?”
Bitstamp tutup kurang lebih selama 5 hari, dan pada saat itu, harga Bitcoin yang awalnya berada di harga 4 juta, menurun ke harga 3,5 juta. Banyak yang berspekulasi bahwa ada kemungkinan 19.000 Bitcoin yang hilang dari Bitstamp dijual dalam waktu bersamaan. Masyarakat yang sudah pesimis dengan Bitcoin, merasa bahwa harga Bitcoin akan semakin turun seperti apa yang terjadi di kasus Mt.Gox. Namun apa yang benar-benar terjadi saat ini?
Selama BitStamp tutup, harga Bitcoin memang anjlok ke harga 3,5 juta namun mencapai kestabilan di titik tersebut. Bersamaan dengan Bitcoin, komunitas pengguna mata uang digital tersebut juga bertambah dewasa. Hasil laporan dari CoinDesk menyebutkan bahwa meskipun harga Bitcoin menurun, ekosistem Bitcoin berkembang pesat jika dibandingkan dengan tahun sebelumnya. Volume perdagangan Bitcoin yang awalnya berada di angka 15 milyar dollar AS di tahun 2013, meningkat menjadi 23 milyar dollar AS di tahun 2014. Belum lagi ditambah merchant dengan penghasilan milyar dollar AS per tahun seperti Microsoft, Dell, dan Expedia yang menerima Bitcoin. Jumlah academia yang meneliti tentang Bitcoin pun meningkat tiga kali lipat dari tahun sebelumnya. Semua ini menunjukkan bahwa Bitcoin tetap bertahan meskipun diterjang dengan berbagai musibah.
Kini BitStamp.net sudah kembali beroperasi dan mereka memberikan biaya transaksi gratis kepada membernya untuk berdagang Bitcoin di tempat mereka selama seminggu demi menebus kesalahan mereka. Tidak seperti Mt.Gox, BitStamp berjanji akan mengganti rugi semua Bitcoin yang hilang kepada pemilik masing-masing. Saat ini, komunitas Bitcoin sudah mulai dewasa dan bertanggung jawab dengan keberadaan cryptocurrency yang mereka punya. Pelajaran yang dapat kita petik adalah selama kita masih percaya dengan Bitcoin, maka Bitcoin tidak akan mati. Meskipun banyak musibah yang menerpa, potensi yang dimiliki Bitcoin bukan berarti menjadi tidak berarti. Bitcoin, hingga detik ini, adalah teknologi pertama yang dapat merubah dunia finansial menjadi tempat yang lebih baik, lebih murah, dan anti politisasi.
Bukankah itu yang sebenarnya kita inginkan?
