Sorry------Is reading music similar to typing on a computer keyboard?Yes sheet music and computer keyboard typing are in essence both just typing letters.For computer keyboard typing the letters are the letters of the alphabet.For reading music the letters are three variants of the notes C D E F G A B. These first variant are the 7 ivory (white) keys on a piano keyboard.The letters assigned to the 5 ebony keys are C# D# F# G# A# known as C sharp D sharp etc. They are also assigned Db Eb Gb Ab Bb known as D flat, E flat etc. That's a bit technical but C D F G A sharp are the same notes as D E G A B flat. It's just a different way of naming the same note like the way French and English Alphabets have slightly different alphabets. The sharps and flats are assigned depending on the type of music that is being played. Also in relation to the answer - reading and playing from sheet music is more complicated than typing on a keyboard because reading sheet music and playing an instruments requires both left and right hand are typing two different sets of letters at the same time where as with computer typing the left and right are typing the same letters which is easier------How do you clean out a computer keyboard?Well yes, Unless its a laptop, all the keys should be removable, just make sure you know where to put them all when your done.

Well that air comes into the laptop from somewhere. A lot of times that somewhere is under the keyboard. Mr. Kitty may have blocked that flow of air and you may have overheated the whole thing. Not much to be done now, really. First fix the keyboard. Then let's hope nothing else is wrong.

You should be able to listen to what you are playing through the computer speakers while you are playing------how the hell you put (that on top of this ) N in a english keyboard!!!!!!!!!!?Press the key Alt0241 in the numeric keypad. (lowercase) or Alt0209 for Capital letter. (You press the Alt key and keep it pressed while you type the numbers in the numeric keyboard (on the right side of the keyboard)) Alternatively there is an application in Windows usually found under Start>All Programs>Accessories>System Tools>Character Map (or for the more computer literate ...WINDOWSSYSTEM32charmap.exe) And with that you have all the characters, accents and all you will need and you just copy and paste. By the way is called a 'tilde'------Why can't I pop the keys out from the keyboard?I really, really do not recommend removing keys from keyboards, as they are not really designed for removal and cleaning. Using a moist cleaning cloth to wipe the surface of the keyboard along with a vacuum brush to pull things out from between the keys is a much safer approach. If you must, the snaps are located at the top or bottom (usually top) of each key. Start with a non-critical key just in case you damage it trying to figure out where your particular key snaps on.------Keyboard/Piano. How do I get better?I am sorry but for $30 the only kind of keyboard you will be able to get is maybe a Baby Grand Piano. from Fisher Price. Toys R' Us, KB Toys, Target, and KMart all do not offer quality instruments. Those are the cheap ones that are more like "toys" than they are instruments. Learning from one of those keyboards will become very frustrating and your child will probably end up quitting. You can always try searching Musician's Friend for keyboards. Make sure its 88 weighted keys w/ proper action. You can pay with a credit card on their website so you will only be paying $20 something a month. Anything below 88 keys w/o proper weighted keys is substandard. You will never get the feel of a real piano with anything less. Not to mention your son wo not be able to learn lots of pieces with a limited amount of keys. Anyways. if you do manage to find one for under $30 odds are it's going to break anyways. at that kind of price you can rest assured your getting what your paying for. . Also if your son intends on slamming the keys and breaking the keyboard perhaps he is not ready to play
What's the Best Way to Sanitize a Laptop's Keyboard, Screen and Mouse?
What's the Best Way to Sanitize a Laptop's Keyboard, Screen and Mouse?
What's the best way to sanitize a laptop's keyboard, screen and mouse?Disinfectant wipes are my preferable sanitizer. If you using rubbing alcohol, you might damage the keyboard------Can i hook a pc keyboard up to my laptop?You can as long as it has the correct port. If the keyboard has a USB connector, just plug it into one of the USB ports on your Laptop. If the keyboard has a PS2 connector, your Laptop must also have a PS2 port for the keyboard. Sometimes a PS2 to USB adapter will work. Good Luck and keep your computer away for young children; they can choke on small items such as the keyboard keys and some also have small springs. The Laptop keyboard keyboard can be replaced - check this option out from a reputable computer store.------Why is my keyboard not working?It has nothing to do with the motherboard. Your problem must be either the keyboard or the usb driver since a wifi and usb keyboard use the USB port to communicate. Not having anything to go on regarding your system, P. C. , desktop, Mac, laptop? You may have to change the usb port settings to legacy setting for it to recognize the keyboard using that port. Still, if everything is the same in your bios as before this adventure, and If you already destroyed the old windows that you had, your best bet is to use a keyboard that uses the standard keyboard port since it is the only way for the system to recognize a keyboard before a windows installation------are keyboard and piono the same thing? do they have any differences?Yes, of course keyboards are smaller than pianos. Keyboards are electronic, because they are plugged in. But a major thing to note is that though the range of a piano is much larger because it has more keys (usually it can go higher and lower than a keyboard), the keyboard can give you different tones. Usually you can press a few buttons and voila, your keyboarding can sound like a church choir. Press a few more buttons, and you get a drum. My old keyboard from the late 90s even has fireworks, so any new keyboard should probably have cooler tones. Another major difference is that in most cases, a keyboard's keys are not as hard to play as a piano. With a piano, the strike of a key makes a hammer hit a string on the inside, which makes the sound. On a keyboard, one touch of the key simply registers an electronic pitch stored into the "computer" of the keyboard. I started piano on a keyboard, then graduated to an upright piano. For beginners, it is usually more cost-effective to buy a $50-$100 keyboard that can easily be donated or thrown away if the student chooses not to continue than to purchase a $10,000 beautiful baby grand piano that would be heart-wrenching to get rid of. If you plan on learning to play the piano, I recommend that you start with a keyboard first so you do not end up wasting precious money if you do not continue. Other than that, the keys are the same, and people do not have a problem transitioning from keyboard to piano or vice versa, aside from the weight of the keys. Good luck!------Apple Adjustable KeyboardThe Apple Adjustable Keyboard is an ergonomic keyboard introduced by Apple Computer, Inc. in 1993 for the Macintosh family of personal computers. The keyboard attaches to the computer via the Apple Desktop Bus port. The last Apple computer released compatible with this keyboard without using a USB to ADB adapter was the Power Macintosh G3 (Blue and White), as it was the last one with the Apple Desktop Bus. It aimed to solve repetitive stress injuries resulting in carpal tunnel syndrome, after several computer keyboard manufacturers were sued for poor design. The Apple Adjustable Keyboard came with contoured plastic wrist rests, and a separate keypad with function keys and arrow keys. This was the third and last time Apple offered a separate numeric keypad. Unlike its predecessors, it was not sold separately. The keyboard also included volume buttons and a record button on the right side of the keyboard. It was hinged at the top, allowing the user to adjust the angle between the right and left sides of the keyboard. The split came between the key pairs: 5/6, T/Y, G/H, and B/N. The space bar floated midway between the two parts. Although the keyboard addressed several ergonomic problems, it was reviewed poorly due to using a large amount of desk space, mainly because of the optional palm rests. The keyboard uses Alps SKFS switches, which provide tactile feedback with a slightly "clicky" feel.

As much as 20ms total in circuits ( the distance to the loudspeaker) is well achievable by bad design and it makes a MIDI keyboard painful experience for a competent player.Make your system to react as soon as possible to a keypress. Leave debouncing delay for the key scanning software and let it affect only to the time when the releasing of the key is taken into the account. Playing a sound a little too long is much less annoying than a delayed start. A simple debouncing strategy in software is to scan the keys say in every 3 millisecond if the caused 0...3 ms extra delay is not a problem. The maximum value 3 ms is equivalent with about 1 meter extra distance to the speaker which can be acceptable------What photograph-manipulation application matches my specific feature wishlist?I'm curious why you think Photoshop doesn't meet what you want, when it clearly does match everyone of your requirements:Fast. How fast is fast? CS5 runs really well for me. This question reminds me of: Adobe Camera Raw is updated constantly to support the latest raw formatsHDR: CS5's HDR capability is fantastic (ihmo)Macros: Photoshop supports VBSCript, Javascript, and AppleScript. Javascript has it's faults, but given how performant the stackexchange sites are, there is no denying in the right hands, it's incredibly powerful (LIKE A NINJA RIDING ON THE BACK OF A PIRATE)Image Processing: It's photoshop.Images Search tag, yada yada: Photoshop comes with Adobe Bridge with integrates seemlessly with what you want.Mac support: Yep. Runs on a mac.I suspect you are looking for something that is very specific to how you work, and it's very unlikely that you are going to find something. The good news is, if you're inclined, GIMP is open source, so you could add the features you want to the source, and commit them for addition to the mainline------Get bluetooth keyboard working identically to built-in keyboardTroubleshooting is a process of elimination and often requires patience.As a starting point, I'd try to reset both the macOS Bluetooth Device List and Bluetooth Controller. IMPORTANT: This will reset all connected Bluetooth devices, including any wireless keyboard or mouse, so they will need to be reconnected.Before commencing, you will need to have the Bluetooth icon showing in the menu bar. If it is not there, open System Preferences > Bluetooth and enable the option Show Bluetooth in Menu Bar.Resetting the macOS Bluetooth Device List and Bluetooth ControllerFollow these steps:After doing the above, test your keyboard for a while to determine if it's now working better.If it's not, there are other things we can try/test for on the MBP side of things. However, before doing that, the next step should be confirming the keyboard itself is okay. If possible, test the keyboard with another computer and confirm it's working okay with that. If it isn't, then replace your keyboard batteries of make sure they're fully charged and test again.Let me know how you go up to this point and if necessary we'll proceed further------Learning piano via MIDI keyboard questionsQuestion 1) I use an 88 key Roland stage piano with midi out when I need it. Stage because it saves space and fairly portable (still 25kg) and have sometimes packed it away in flight case when not being used. Still requires a dedicated space in any room.Question 2) I got fully weighted because its main purpose was to learn how to play classical piano, but as user15664 says in his post there are different purposes. Also see this previous post: How to gain velocity feelQuestion 3) A good brand piano will feel and sound good. You can listen to demo's yourself on-line but you will probably have to rely on reviews of the hammer action for the feel (since you are new to it)In your original statement, you said you wanted to toy with music production. Majority of cases for which it will be better to use good software pianos. The whole skillet is different and not as necessary to have fully weighted keys (i.e. arranging and tweaking velocities and notes as oppose to flawless playing in a recorded take)And finally, I would reccomend second hand as Digital Pianos depreciate in value like cars.------What features are cursor controlled on the A380 Navigation Display?As far as I know the whole FMC (or as it is called in an airbus: MCDU) is controlled by this cursors. So you don't have the limited options by just using scratchpad and line select keys, but you can graphically interact with the items on the screen by using the cursor.A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight management of the flight plan. Using various sensors (such as GPS and INS often backed up by radio navigation) to determine the aircraft's position, the FMS can guide the aircraft along the flight plan. From the cockpit, the FMS is normally controlled through a Control Display Unit (CDU) which incorporates a small screen and keyboard or touchscreen. The FMS sends the flight plan for display to the Electronic Flight Instrument System (EFIS), Navigation Display (ND), or Multifunction Display (MFD).Wikipedia - Flight Management System------How to test which button is stuckIn the first instance, maybe give the keyboard a damn good blow with a can of compressed air, in case there is debris under the keys. Biscuits are GREAT for screwing up keyboards.Failing that, I would give Dell technical support a call and explain your problem as it is still under warranty. It would save you some time if you ran through the diagnostics (F12 on boot up and then select the diagnostic option) before calling. It might save them getting you to do it while on the phone.(sorry if this does not apply to you-) Over here in the UK, if you tell them that you're comfortable changing the keyboard and ask nicely, they will just send the part and let you do it yourself. Not sure whether this will work in your neck of the woods but worth a go nevertheless, nothing to lose right?Trying to fix it yourself might end in a completely broken key. If you are lucky enough to remove the key without snapping the plastic, the scissor mechanism is a pain the backside to put back together again------How to change keyboard layout by USB dongle?There are several parts to this question.1) Can you make some kind of hardware that permutes keys from an USB keyboard as if it were a customized Dvorak keyboard?Yes, you can. You can use any embedded computer that has both an USB host and a USB client port. However, you will have to write the software for that yourself: It's very unlikely that ready-made software for that exists. The software will have to translate HID events from the physical keyboards to the HID events corresponding to the Dvorak layout, but that is not very difficult.2) Will you be allowed with your own private keyboard or your own piece of hardware that you can put between an existing USB keyboard and a PC in a high security place?If the people who are responsible for security are not completely stupid, they will allow no extra hardware at all - no keyboards you carry with you, no commercial "dongles", no custom self-made "dongles". And you'll get on the watch list for even asking.So if you are asking because you need a Dvorak layout in such a place, this is not a viable solution------How windows boots up in hibernate mode using keyboard?The Wikipedia article was imprecise, and I already fixed that. It's true that hibernation ends up with exactly the same device power state as when regular shutdown is applied. But while that state is called a "shut down", in modern computers some basic electronic modules still function. It's the motherboard that decides what to do, once it gets in that state - according to it's construction and features designed by manufacturer.These features are eg. powering up by WakeOnLAN, keyboard shortcut, mouse move or time-preset launch. Or even pressing the front power button, which is not a real circuit breaker like in "the old times", but just an electronic, low-power "sensor" that, when pressed, allows that inner electronic module to know you want to power the rest of modules on.To completely shut the computer (motherboard) down, you still have to completely unplug it's power sources or, in case of some desktop PC-s, use the power switch on the PSU.Mind though, that RAM is truly powered down when in hibernation state. It's content gets stored on the hard drive right before shutdown and then gets recovered when you start computer again.

The keyboard itself could be bad, could have a loose or broken connection from the PS2 connector to anywhere inside the keyboard. Or the port on the computer has gone bad. You can get a PS2 keyboard for about $20.00 these days, i would try connecting a different keyboard and see if it works or buy a USB keyboard in case the PS2 connection is messed up. If a friend has a spare keyboard, i would try borrowing it and see if that works. As for what would cause this to happen, could be age on the keyboard as in wear and tear mostly. It just gets worn out after a while or depends on how good the keyboard was made, a good keyboard lasted me years.

Some phone wall chargers connect to a USB port then back to your phone. Your keyboard would have to have a USB port. Next. Having a converter, that makes a USB port from a different port on your keyboard. Another would be bluetooth. But I do not know how that would work out with the information from the keyboard to transfer to the phone. With a lab top. Connect your phone to the lab top using the USB from your charger. I hope one or more of these possabilitys work. Good luck.

The board was very dusty and while attempting to clean it I swiped multiple keys at once and then had no volume. I did not press the volume/mute buttons. I've tried everything I can think of, but to no avail. Is there a combination of keys to press to cause this? Or is the keyboard dying? Thanks------how to turn off my pc without a mouse and keyboard?The mouse and the keyboard are your only input devices. Cut the power off.

Best of luck, you really can not go wrong anymore out there. they are all fine now a days. its mostly about preference. Are you going to be playing it through speakers or not? (This will determine if you want nice speakers on the keyboard itself) do you want light up keys. do you want the ability to connect to an amp or computer. etc. (it can get complicated but mostly any keyboard out there will work for beginners. Hope this helps.------Keyboard percussion instrumentA keyboard percussion instrument, also known as mallet percussion, is a chromatic melodic percussion instrument arranged in a similar pattern to a piano keyboard and played with hands or percussion mallets. Keyboard instruments for children, such as ones used in the Orff Schulwerk, may be diatonic or pentatonic. Despite the name, keyboard instruments such as the celesta and keyboard glockenspiel are not considered keyboard percussion, owing to the different skills required to play them. These instruments are percussion instruments in most senses but are part of the keyboard section rather than the percussion section of an orchestra. Keyboard percussion instruments do not possess keyboards as such, but instead follow the arrangement of the keyboard. Keyboard percussion instruments include marimba, xylophone, vibraphone, glockenspiel, and tubular bells.How can I get the smell out of my keyboard bag?First unplug it then pop out all the keys and clean it with a clorox wipe or something like that, then clean each individual key and put them back in the keyboard.

I simulated this with Virtual Machines. I started Notepad in my host, left my mouse in this Kali Window, then used the keyboard to bring up the Host Notepad window. All worked to that point, but then the mouse clearly came with me to Notepad.VMware simulates this because there are two different machines. But it is done with one single monitor and the mouse still goes with the keyboard. You can see this happen on screen.So I really do not think this will work------How do I turn the power off of my Logitech LX710 Keyboard?I do not believe Logitech includes power buttons on their keyboard - mainly because there is not much power running through it at all times whereas there's a power switch on the mouse because the laser sensor is constantly on and drains much of the power. In other words, you would have to remove the batteries to turn the power off on the keyboard, but in reality it's not necessary because it does not draw much power on standby.------Keyboard matrix circuitA keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys-sufficient for a full five octaves of range (61 notes). By scanning these crossings, a keyboard controller can determine which keys are currently pressed. .------In china how do they type chinese with computers when there are english letters on the keyboard?Well, I have seen and used a Japanese keyboard, and I am pretty sure Chinese and Japanese use the same system.

It was designed to overcome two limitations on the traditional piano keyboard: the large-scale geometry of the keys (stretching beyond a ninth, or even an octave, can be difficult or impossible for pianists with small hands), and the fact that each scale has to be fingered differently. Instead of a single row, the Jank keyboard has an array of keys consisting of two interleaved manuals with three touch-points for every key lever, making six rows of keys. Each vertical column of three keys is a semitone away from the neighboring ones, which are in the alternate rows. Thus within each row the interval from one note to the next is a whole step. This key layout results in each chord and scale having the same shape on the keyboard with the same fingerings regardless of key, so there is no change in geometry when transposing music. Furthermore, the use of multiple rows allows the pianist to more naturally follow the contour of their hand and accounts for the different lengths of the fingers. The configuration retains the colouring of traditional keyboards (white naturals, black sharps and flats) for pedagogical purposes. For an 88-note (full size) keyboard, there would be 264 keys in total, with each note playable by three keys in vertical alignment. In the picture above, the white keys have been coloured to show how the keys are interconnected. Instead of 123 cm (48 in) the keyboard is only 89 cm (35 in) wide, and the smaller key size allows reaching wider intervals. The Jank Keyboard caused a stir at the time of its invention, in large part due to its unique look and the intelligent design behind the keyboard. American piano manufacturer Decker Brothers put the keyboard into production around 1891, and the Paul de Janko Conservatory of Music was established in New York around the same time. There was even a manual written by W. Bradley Keeler called How to Play the New Keyboard. Despite all this, the Jank keyboard never achieved wide popularity. Music educators were not convinced that the benefits of the new keyboard were enough to challenge the traditional keyboard. Both reasons left keyboard instrument manufacturers afraid to invest in a redesigned keyboard which promised to have only marginal commercial success. Many embodiments of this keyboard have appeared since its conception. Jank himself (in German patent 25852, dated 14 January 1884) originally chose a key shape which resembled the slim, black keys on the familiar piano keyboard. A year later (in German patent 32138, dated 1 July 1885) the keys became wider and shorter. Other inventors have filed patents for keyboards which are substantially similar to his design, differing most often in key shape or instrument to which those keyboards are affixed. (For example: John Trotter English Patent 3404, 4 March 1811, William A. B. Lunn devised in 1843 under the name of Arthur Wallbridge a sequential keyboard with two parallel rows of keys, each in whole tones. Miguel Theodore de Folly, 1845,Useful Registered Design Number 448 for a geometrical keyboard for the pianoforte, Gould and Marsh , Edgar , Cramer , McChesney , Stewart , Adams , Nordb , Barnett , Reuther , and Firestone .) The most recent patents are for MIDI compatible instruments.

What's the Best Way to Clean Out the Keyboard of My Laptop?
What's the best way to clean out the keyboard of my laptop?If you run a vacuum cleaner over the keyboard you wo not damage the processor but you will damage the keyboard the best way to clean it is to go down to you local computer shop they should sell cans of compressed air for cleaning dust and the like and in you case crumbs out of a computer the pressure is not too high so it wo not do any damage------When the Keyboard Breaks: Live in ChicagoWhen the Keyboard Breaks is a live album by progressive metal supergroup Liquid Trio Experiment. The album was recorded during a live show of Liquid Tension Experiment in Chicago, Illinois. The album came about when, during the track "Universal Mind", Jordan Rudess' Roland Fantom-G8 keyboard started playing half-step higher notes on every fourth key: So I am playing along, everything's fine, but all of a sudden I started hearing these half-steps. It was as if I was playing in C but somebody else was playing in C-sharp. I was looking at John Petrucci, like, 'What the hell are you doing?' But then I saw him stop for a second, and I looked down at my hands and thought, 'What is that?' I realized that every time I played a C, the keyboard would also play a C-sharp; every time I played a G, it played a G-sharp, and so on. It was playing everything in the worst possible dissonant way.Following the song, he went off stage to figure out a solution, since he did not have his usual technician nor a substitute keyboard. In the meantime, the other three musicians decided to improvise until Jordan was ready to come back. Jordan had to stay on the phone with Roland in Japan for at least 20 minutes trying to figure out what was wrong. The other three just continued to jam with drummer Mike Portnoy giving updates every now and then (the determining point for the track splices). In the end, Rudess took John Petrucci's guitar and started jamming, then Petrucci took the bass, since Tony Levin was playing the Chapman Stick. When that jam was over, Portnoy ended up taking Levin's bass and Charlie Benante ended up playing drums. The keyboard was never fixed that night. The production of the album was not official, as it was taken from a live stereo recording from the mix off stage. Thus there was no way for it to be properly mixed so everything is how the audience heard it. The name of the album alludes to the track "When the Water Breaks" from Liquid Tension Experiment 2.------Voice control and keyboard shortcutsSpeech recognition usually refers to software that attempts to distinguish thousands of words in a human language. Voice control may refer to software used for sending operational commands to a computer or appliance. Voice control typically requires a much smaller vocabulary and thus is much easier to implement. Simple software combined with keyboard shortcuts, have the earliest potential for practically accurate voice control in Linux.------Logitech G110 keyboard randomly stops working while playing games?Check if you plugged the keyboard in an USB 3.0 port by accident. Those Logitech keyboards with a display act funny when in an USB 3.0 port. I had the issue with both my G19 and a G510 keyboard. If in a normal USB 2.0 port, it could be an issue with the Logitech software. They did away with their SetPoint software for having constant issues and their gaming keyboard software is not fully optimized either. Check for an update to see if that would solve the problem.------What does the " symbol mean in a keyboard piece when attached to a note?Check this out.Thumbing is the act of playing with one or both thumbs on the keyboard below the keyboard on which the rest of fingers are playing. This technique was developed in the late 19th century, and fell out of use after 1930. While at first an organist not used to this technique will only be able to use it to play isolated sustained pitches, organists accustomed to this technique are capable of playing moving lines, although the speed possible is less than that of using all five fingers. A composer who wants to use this technique would be wise to spend some time at an organ console to find out what is physically possible as far as the reach of a hand. Failing that, a composer should refer to a piano keyboard to verify that the requested hand positions are comfortably possible. When notating a passage using this technique, one should place the notes to be thumbed on a separate staff between the "right hand" and "left hand" staves. One should also mark the notes to be thumbed with a "" symbol.
Are Online Exam Proctoring Services Efficient and Trustworthy?
Are Online Exam Proctoring Services Efficient and Trustworthy?
According to an article of the German news site "Spiegel online": short summary of the article in English:There was a test exam that was supervised externally using the students smart phone and computer. The student used his own computer where he had to install a special software. After some technical trouble, the connection to the proctor had been established. The student had to identify showing his passport, he had to present the room to the proctor via his mobile phone camera. He ensured that there are no illegal tools (additional books etc.) or other persons in the room.The mobile phone was then set up to show the student as well as his computer and keyboard. The tool on the computer enabled access of the proctor to everything that is shown. Then the test started and the proctor appeared to continuously observe him. However, the student tried cheating and was VERY successful by doing so. The student was able to read from an undetected cheat-sheet that was pinned to the wall in some distance.The student managed to open some book and to read in his notes, despite this was not allowed. Finally he even stood up and walked around in the room. The proctor did not react. All this cheating remained undetected. The proctoring service has some statistics that mentions 4000 detected cheating attempts in more than 63000 online exams. The article finally raises the question how many more undetected ones took place. From my personal experience in IT security: A computer system (and especially a room) that is under the student control should never be used for such an exam since its security cannot be guaranteed.Clone the monitor signal, have a secial kernel driver in lace, have the exam running in a virtual machine, ..., there are many ideas. Some might work, some won't. It is a similarly difficult task as reventing cheating in online games: A lot of effort goes in ut you NEVER get rid of cheaters. As long as there is some motivation (there definitively is for university exams!), you will find eole heling you cheat.

I am going to wipe the computer's memory. I am going to wipe down the computer's memory.In this example, it doesn't make any sense to use wipe down with computer memory, because that's not something that can be physically touched. I am going to wipe the car. I am going to wipe down the car.Here, I would have no idea what wiping a car isbecause you can't delete cars. On the other hand, wiping down a car generally means applying a cloth to remove dirt or water.(Note that we often omit prepositions in speech. if somebody actually said wipe the car, I would understand from context that they meant wipe down the car. As such, the expression without down is not actually wrong in regular discoursebut it wouldn't be quite as natural, and I'm trying to show the literal difference between the two.)To be more specific, compare the following situations.Sitting at a computer keyboard and typing commands: I am going to wipe the motherboard.  I am going to wipe down the motherboard.Holding a motherboard and cloth in your hand: I am going to wipe the motherboard.  I am going to wipe down the motherboard.The object in the question appears to be a blackboard, on which there is writing. This is a particular instance where the two different senses of wipe can be applied to the same thing.It can accept wipe in the sense of removing information. It can also accept wipe down in the sense of cleaning. I am going to wipe the board, so write down what I have written. I am going to remove (delete) the information from the blackboard. I am going to wipe down the board, so write down what I have written. I am going to clean the chalk off of the whiteboard.So, both are fine. Which you use is based on the specific sense you are trying to convey. Are you talking about the information represented by the blackboard or are you talking about the physical chalk marks? (Note that the final result is mostly the same, with the one sense impacting the other.)------Are ergonomic keyboards better for your health?Yes, there are many documented advantages.Copied from here and then adapted:...the adjustable keyboard was more comparison with the conventional keyboard.Tittiranonda, Rempel, et al.

(2000) Finger motion, wrist motion and tendon travel as a function of keyboard angles...the tested split keyboard configurations are beneficial in promoting a neutral wrist position, which theoretically would decrease exposure to WMSDs such as tenosynovitis in the wrist and carpal tunnel syndrome.Marklin, Simoneau (2001) Effect of setup configurations of split computer keyboards on wrist results identified a reduction of symptoms, an improvement in functional status, preference for and increased satisfaction with the alternative keyboards, and maintenance of typing speed and accuracy for both groups.Ripat, Scatliff, et al. (2006) The effect of alternate style keyboards on severity of symptoms and functional status of individuals with work related upper extremity disorders....split keyboards with a slant open angle of 10 degrees to 12.5 degrees...are effective in placing the wrist in near neutral ulnar/radial deviation when typing...and tilting the keyboard halves 20 to 30 degrees is effective in reducing forearm pronation to approximately 45 degrees.Design features of alternative computer keyboards: a review of experimental data.Analyses of...six studies indicated that the Adjustable Open-tented keyboard had a large effect on pronation and ulnar deviation...The effect of three alternative keyboard designs on forearm pronation, wrist extension, and ulnar deviation: a meta-analysisNote that there are also advantages in using a soft-touch keyboard and a keyboard without a keypad.------ASUS EeePC FnF2 ruins wireless until restartI have an Asus EeePC myself too, the 1005PE, but im using Lucid 10.04 instead. Ive bought it soon after Lucid was released, and decided to stick with an LTS release. After all, netbooks have limited hardware, and i depend on it on a daily basis, for work and college, so bleeding edge is not needed, stability and long term support comes first.At least in my particular combination, the FnF2 key works perfectly. I can (and i do) switch wireless on and off several times a day. Sometimes I have problems turning bluetooth on and off, requiring restart, but since Eee900 has no bluetooth, it shouldnt worry you.Also, I didnt have to install any driver. The ones out-of-the-box recognized my harware, from touchpad to wifi and even bluetooth. So, my suggestions are:Why not try Lucid 10.04? Its LTS, so it will be supported for 3 years instead of 18 months.If you dont use Maverick's Unity, youre already missing the biggest change in that release. So Lucid will look very similat to what youre used to.Power consumption in Lucid is smaller than Maverick. For a Netbook, battery life is crucial.Ive downloaded and installed Jupiter. Not for the Fn keys, but for power management. I strongly recommend it. It really improved my battery life from 8 to 12 hours. HUGE improvement. Check out my answer on a similar question for some info about Jupiter. And yes, it also improved Fn control by enabling OSD Notifications for every Fn key, and it does have independent bluetooth and wireless enable, something my Fn keys do not.So, why not try it? Lucid 10.04 Jupiter may be your solution for the FnF2. Even if they dont, you wont lose much compared to your current setup (Maverick minus Unity is almost the same as Lucid), and you will get some side-benefits as well, battery life and LTS support to name a few.You dont need to touch your HDD to try it... use a Live Session to see if FnF2 keys work. You can even install Jupiter in a Live Session. Or repartition your HDD to have them both installed side-by side until you feel safe about it
