Windows ships with two calculators. The normal one and a scientific one that can be enabled in the View menu of the calculator. The normal calculator offers basic functionality while the scientific one adds functionality that most users do not need. The normal calculator in Windows uses a small window which appeals to many users.

I’m not sure what is causing it but I do know that a lot of users have difficulties opening PDF files in browsers. In my former tech related job I had to find a way to find out why those pdf documents were not shown in the Browser correctly and how it would be possible to fix this issue and make them display correctly.

Thunderbird saves the attachments together with the mail message which means that the mailboxes can grow rapidly if you regularly receive large attachments. This slows down Thunderbird eventually and could also pose a storage problem if you use the default profile location to store your emails.

Windows Media Player 11 is constantly monitoring several folders in the My Documents folder structure for media changes. If you do not use WMP 11 as your main media player you might be wasting resources caused by this monitoring. By default the My Music, My Pictures and My Videos folders are monitored and new files are automatically added to the Windows Media Player 11 library.

The message “Windows cannot open this file2 is always displayed when a user tries to execute a file with a file extension unknown to Windows. Windows is giving the user the option to search the Internet for clues on how to handle that file or pick a software from the list of installed applications of this computer.

Windows XP has a very confusing way of listing files in directories. Let me give you a small explanation. How would Windows XP sort the files abc1, abc101, abc4, abc401, abc8 ? No, it is not like I have ordered them in the last sentence. The default order for those files would be abc1, abc4, abc8, abc101 and abc401. The reason behind this is that Windows XP considers the numbers to be just that which means that 101 is a larger number than 4 or 8.

Did it ever happen to you that a double-click on a file lead to moving the file instead for a pixels in the direction that you moved the mouse ? If you try to double-click a file and move the mouse for more than four pixels after the first click the file will be moved instead of executed.

I recently visited a friend of mine who had a huge problem with his computer. His main hard drive was filling with data rapidly although he only had the operating system and some applications installed. It turned out that System Restore was using more than 12 Gigabytes of space on this drive alone.

The hard drive properties window gives information about used and free space both in numbers and as a pie chart, offers a Disk Cleanup button, a way to change the drive description and it is the location where you turn drive compression and drive indexing on and off. If you have more than one hard drive you might want to get their information all at once instead of right-clicking the hard drives one at a time.

My dllcache folder in system32 has a size of almost 450 Megabytes on my Windows partition. The dllcache is used to replace a system file (dll) that has been changed with the original one. It bothers me that this feature of Windows takes up so much space on my hard drive. It is even more serious in my case because I decided to have a rather small Windows partition, every byte counts if you know what I mean.

If you do use Opera you might have noticed that Opera seems to always bring up the save to dialog and you have to browse to the download location even if you downloaded a file of the same type just a minute ago. The line “Remember choice and do not show dialog again” is grayed out and can’t be checked as well.

Windows Media Player adds context items to the right-click menu of several multimedia files even if you do not use this player to play those files. It would be nice to get rid of those items in the context menu to decrease the size of the menu and have only options in there that are needed. There is however no obvious option to remove the three entries which means that we once again have to rely on the Registry to fix this issue.

Nothing can be more frustrating than to listen to some great tune on Internet Radio which suddenly starts to skip ruining all the fun. The following, pretty obvious method, helps most of the time if you regularly experience stutters, slowdowns or skippings when listening to Internet Radio.

Emails can be send to several recipients at once by using the CC or BCC fields which send a Carbon Copy or Blind Carbon Copy to the recipients listed there. Using the BCC option is useful if you want that every recipient is only able to see his email address and not the email of everyone else who receives a message.

I was specifically asked by a reader if it was possible to search Mediafire for files like videos, music and applications and you know I can’t say no if one of my reader requests something. Mediafire is a file hosting site like Rapidshare and Megaupload with apparently no storage limitation and a file size limit of 100 Megabyte.

I had lots of messages in my Thunderbird mail accounts. More than 1200 send messages and more than 1500 incoming message. The send messages alone had a size of more than 25 Megabytes while the incoming a combined size of more than 800 Megabytes. This made my decision to clean up the mails even easier.

I think it is really interesting that a lot of unusual problems start to appear on blogs and websites that users have with Windows Vista. Makes me think why no one found out about it during the extensive beta tests but that is another story. The How-To Geek is reporting a problem with large zip files under Windows Vista.

Not long ago, my system popped out a dialog saying “Error” in the title and offering two ways to go in form of two buttons below it – Yes and No. I was trying hard for a while to find out about the right answer but I never really did find it because I did not know what the error was all about. I suppose I’ve saved the world by choosing the right answer, the world didn’t blow up after all… And now seriously :)

Bin and Cue, Img and Iso files are CD and DVD formats that store all the information of the CD or DVD. Users come across them on many occasions such as Linux distributions, Open Source software distributed on CDs and of course when downloading files from P2P networks, ftp, irc or the Usenet.

Kline over at Connected Internet posted an interesting article detailing 10 simple ways to speed up Windows Vista. I actually tweaked Windows Vista right when I unpacked my notebook which had Windows Vista Home Premium preinstalled, got rid of a lot of useless stuff that I did not need anyway.

While the automatic update function in Windows XP and Vista is a good way to keep your system up to date with the latest patches it has the nasty habit to nag the user after downloading the patches to the computer. I suppose everyone has received a message that asks the user if he wants to reboot now or reboot later in XP or the dialog box that asks you to restart your computer to finish installing important updates in Windows Vista.

Did you ever have the problem that you wanted to change the file association of a certain file type but were not able to ? The normal way of right-clicking the filetype, clicking on Properties, then on the Change button next to the Opens With entry and browsing to the executable did not work for me because the executable was not added as the default software.

Frozen iPods are more common than you might think. Read on before you go out and buy a new iPod just because you can’t get your old one fixed. As I said, frozen iPods are common and there are a few steps that you can undertake that will most likely fix the iPod and get it out of it’s frozen state.

Don’t you hate it when someone sends you an email containing links or other email addresses that are so long that your email program uses several lines to display them ? This is apparently a matter of how the email client in question is handling urls and emails that are to long to be displayed in one line.

My biggest complaint that I have when using Open Office is the speed of the application. It loads terribly slow for instance and it only topped by the time GIMP needs to startup. Way to slow to edit a document quickly in my opinion. The guys at Zolved found a way to speed up Open Office by editing a few settings in the software’s settings.

The Windows taskbar is not only useful for showing which programs and folders are currently active on your system but can also he customized to store permanent shortcuts to applications and folders as well as links to Internet websites. I would like to show you how to configure your taskbar to add your favorite websites as well as links to your most commonly used applications and folders to it.

P5chin who is a regular reader of my blog send me a tip which I immediately had to write about. I don’t know a single computer user who is not unhappy with all the cables, power sources and external devices cluttering the place on and beneath the desk.

It’s been a long time since Wildbits started to provide an amazing and free music identification software called Tunatic which helped me many times identify a song I loved. This happened for instance when I recorded Internet radio streams without information about the artist or the song name. I bet you’ve happened to be in such situation too.

The defragmentation tool that ships with Windows is pretty basic and does not offer features that are needed for instance if you have more than one partition or hard drive. Some users would like to defrag all of their hard drives at once while they go to work or sleep.

I mentioned three days ago in my blog that the Autopatcher team released the June 2007 patches for Windows Vista and just now they announced that the updates for XP can be downloaded as well from their sites. In case you missed the last post here is what Autopatcher does.

Relakks offers a easy and anonymous way to be on the Internet by tunneling all traffic through their service which is based in Sweden. This effectively means that your home IP is not revealed to websites, p2p clients and servers and all other computers and servers that you are connecting to.

The traffic is encrypted as well which makes it unlikely that someone is able to spy on it including your ISP. I have been writing about Relakks before and they had some serious troubles with their service at the beginning which turned off many users who tried the service initially.

Windows XP offers a function that is hidden deep inside the user account menu. It is possible to create a so called password reset disk that can be used to reset the password of the account is has been created for. You simply pop in the disk if you have forgotten your password and use it to create a new one.

There is normally no way to store the components of the password reset disk on an usb device because Windows XP is unable to access it during logon. It is not a problem to store the files on an USB device but you will face troubles when trying to access it if you lost your password.

Everton from Connected Internet posted a nice article where he is detailing his steps to add tags and cover artwork to his mp3 collection using a few selected freeware programs and iTunes. He suggests to use Picard for the tagging process because Picard is able to add most tags of known albums automatically.

The only information that are not added by Picard are the cover artwork and the genre. It is understandable that the genre is not being added because it is sometimes difficulty to select a genre that everyone would be comfortable with. Itunes will be used to add the cover artwork right from the iTunes store.

One of the most annoying features of Windows Vista is the login screen that displays all user accounts on the system. You have to click on one of the accounts and enter the password from that user to be able to login and use Windows Vista.

I don’t think it makes that much sense to display this information if you login with the same user most of the time. Security should also be no concern because it is not that complicated to access the data even though you do not know the password of that specific user.

The following fix should help users who do have problems with some virtual console games for the Nintendo Wii that display only a black screen after starting them while the sound remains normal. This does not work in all occasions but should work if you get the Wii menu when you press Home and works only for games that received an update for the interlaced mode.

Try out the following to see if this fixes the issue. Start the game normally until you see the black screen. Connect the Nunchuck to the Wiimote and press Home to see the menu options. Now press A + 2 + Z together which should result in a short “ping-like” sound.

This should have activated the interlaced mode. Leave the menu and you should see the normal game screen and not the black screen anymore. To change the mode again press A + 1 + Z using the same method as above.

It happens sometimes that you find duplicate mails in your inbox in Thunderbird. This could happen for instance when you pull new emails from the mail server and get disconnected during that process. It could happen then that those emails will be retrieved again when you check for mails. Thunderbird has a nice hidden variable that defines how it should treat duplicate mails and I’m going to tell you how to set it correctly so that duplicate mails are removed automatically.

After introducing Teachertube just a few days earlier I received an email pointing me to Vidipedia which is a video encyclopedia, basically Wikipedia with Videos. The principle is of course the same. You search for a phrase or browse a category on Vidipedia and one or more results are shown on the next page. If a single result exists it will be shown in video player mode which loads and plays the video automatically.

The first thing that came to my mind when I read “Attempted copyright infringement” was the term thought crime. It seems that Attorney General Alberto Gonzales is pressing the U.S. Congress to enact a sweeping intellectual-property bill that would increase criminal penalties for copyright infringement, including “attempts” to commit piracy.

Microsoft decided that The Aero interface would not be available for Windows Vista Home Basic users. I personally dislike the new trend to offer several versions of a program with different functionality naming them basic, premium and ultimate. It confuses consumers who have enough troubles to work with the operating system less alone deciding which of the many versions of Windows Vista would suit their needs.

I know that this may sound funny but I also received the error “The memory could not be read” during Windows startup. The funny thing is that this error and the error “the memory could not be written” are not related to each other. I found a fix that helped pretty fast. The memory could not be read is apparently a Java error which is causing the problem. You find a big explanation with various solutions at a official Java website.

I have lately been getting the error message The instruction at “0x62e2cc0f” referenced memory at “0×00000000″. The memory could not be “written” in Microsoft Windows XP. This happened frequently when I tried to play certain avi video files. I first thought that I had a memory problem, maybe defective RAM or bad sectors on my hard drive but soon found out that this was not the case. It took me a while to realize what it was. Once I knew where the error came from I was able to wave goodbye to the memory could not be written and watch all the avi movies on my system without problems again.

The following article describes two ways of speeding up hard drives in Windows Vista. The first tip describes a way to speed up SATA drives and the second to speed up USB drives. Both options can be easily configured in the Device Manager. Advanced write caching features are supported by Windows Vista but not enabled by default. I’m not sure why Microsoft decided to disable the feature by default but it surely helps system performance to enable it. Just make sure you have an SATA drive installed.

It was possible to define the percentage that the System Restore feature in Windows XP allocated from a hard drive. Windows Vista has System Restore build in as well but no obvious way to define the percentage of the hard drive that System Restore allocated. Microsoft thought it would be a good idea to hide the setting well and allocate 15% of the hard drives capacity to System Restore. On a 300 Gigabyte drive System Restore would allocate 45 Gigabytes of space !

In their drive for a uncomplicated system they restrict user possibilities to create a system the way they like. It is becoming a closed system with the owner of the computer being a user instead of someone who can actively alter his system the way he wants. To change the System Restore size in Microsoft Windows Vista you have to rely on the command line utility vssadmin.

If you thought that the last Multi-touch technology videos that I have been showing here at Ghacks have been cool then you should see this one. This one is a presentation by Jeff Han who is a research scientist for NYU’s Media Research Lab during TED (Technology, Entertainment, Design) 2006. Jeff Han describes his technique the following way: “Our technique is force-sensitive, and provides unprecedented resolution and scalability, allowing us to create sophisticated multi-point widgets for applications large enough to accommodate both hands and multiple users.”

Thunderbird displays only the message count of unread mails of every folder by default. I tried to find a way to display the count of all messages instead which would help me get a better overview of the amount of mails inside a folder. I wanted to make sure that the unread messages number would still be shown as well.

The option to activate the message count for all mails is kinda hidden in Thunderbird. You need to enable the “Show Expanded Columns” option first which can be done by going to Tools > Options, selecting the Advanced tab and checking “Show Expanded Columns in the Folder Pane”.

I knew that something like that was going to happen eventually and it did happen with the releases of “Stranger Than Fiction” and “The Holiday”. Mick B posted the story on a new blog that he apparently created just for the purpose of bringing the news to the world. He rented the two DVD movies (from Sony Pictures) and tried to play them on his Sony DVP-CX995V DVD player. Both DVD movies did load until the splash screen was shown and stopped loading from that moment on. After 60 seconds the DVD player did turn itself off with no apparent reaso

We all know the drill. You want to buy clothes in a shop or online and have troubles finding clothes that perfectly fit. A device called Intellifit tries to revolutionize shopping by measuring your body and suggesting those clothes from selected brands that fit the best. This is done by scanning the body once for about 10 seconds using radio waves that make it possible to get an accurate body measure with hundreds of measure points of which many or used in the clothing industry today.

Readyboost is a disk caching system introduced in Windows Vista that relies on flash memory to boost system performance. The effect is not that noticeable but some users swear on it and I do not want to discuss the usefulness of Readyboost. The USB device has to meet some requirements before it can be used for Readyboost mainly that it needs to meet certain read speeds. Many older USB devices do not meet these requirements and refuse to be used as Readyboost devices in Windows Vista.

DVD region codes, how I hate them. I never quite understood why every player and dvd created had to have a region code implemented to prevent playback of DVDs from other regions. If I was to move from the United States to Germany or Britain I would have to import all DVDs for my US DVD player because I would not be able to play DVDs sold in Germany or Britain on that player. The other possibility would be to buy a European DVD player which would not play my US DVDs that I purchased back in the States.

A reader of my site asked which program I was using to transfer files between my local computer and my dedicated server. The question looks easy to answer at first glance but actually it is not that easy. I’m actually using two ways to connect to my dedicated server depending on the tasks at hand. I use Putty to connect to my dedicated server when I want to administrate it: create new virtual hosts, ftp accounts and the like. I do use WinSCP for all other tasks, mainly for opening a secure connection to my dedicated server which uses SSH.
