Guys kindly help me with my design..here are the details..this is about bluetooth programming and interfacing.

i have to program a particular cellphone to communicate with pc through bluetooth...how am i going to do that?i dont have any idea about bluetooth protocols.the problem is i only know how to access the rs232 parallel port of a pc.. that means the bluetooth module must be connected to that rs232 of the pc so i can access it easily through programming the pc.my objective is just send bit signals from the cellphone then access it from the pins of the rs232.particular signal corresponds to a particular action in the pc which is interpreted by the program in the pc.i will use c++ to access and analyze bit signals sent by the cellphone .is there any bluetooth module which can be connected to rs232 parallel port directly?i find it hard also studying programming in the cellphone especially its bluetooth.any1 there can help me...guys please help me or else my teacher will not allow me to graduate this year.iam college graduating student...tenx!Godbless!

I want to configure my linux machine as a router? i have a ppp0 broadband connection.?

I also have another m/c(linux) connected using crossover. the linux router i was taking abt has 2 ethernet interfaces.... one for the ppp0 broad band connectiona and the other one for the other linux machine. i want to have net access in another machine as well... how do i do that without using squid??

I want to configure my linux machine as a router? i have a ppp0 broadband connection.?
Enable packet forwarding on your linux machine by editing /etc/sysctl.conf or by setting /proc/sys/net/ipv4/ip_forward to 1. Using iptables, allow forwarded traffic from the other system to pass through and also SNAT it before it leaves for internet.
Reply:No need to use squid. Just configure simple iptables rules in your linux box. you will find on in iptables HOW TO. Before doing this you would need enable routing in ur linux box. All these details are in the same HOWTO go get it and start working.


Waise you can also try ipcop distro, its very easy to install, configure and rock solid in performance.

What classes will I need to take to become a quality game programmer?

I have searched everywhere for classes that I should take and I came up with these:





Game Programming (duh)


C++ Programming (or maybe Java)


Assembly Level Programming


Computer Architecture


Software Engineering


Computer Graphics


Data Structures


Algorithms


Communication Networks (for MMOs)


AI and Expert Systems


Human Factors (for drop-dead interfaces)


Linear Algebra


Vector Calculus (0_o)


Physics





Have I missed anything, or have I included anything that will be unneccesary? I sincerely hope that Vector Calculus will not be needed because quite honestly, it scares the *censored* outta' me.





Also, while your thinking about that one, here are a few more questions...





2.What is the average salary for a decent programmer? An expert programmer? How about one that barely managed to get the job?





3.How coveted is this job? How much competition will I have?





4.If I decided to take only the game programming classes, would I be incredibly behind if I have not learned C++?

What classes will I need to take to become a quality game programmer?
C++ is a must.


Java will be nearly useless for a professional game programmer for a company that produces console games.





Java is only useful if you do some website games.





Software engineering isn't needed, but it does encompass lots of the theories of game programming.





AI is important, as well as GPU programming (graphics programming).





Physics and Math are extremely important. Study as much as you can and understand it, don't just "get the grade", understand. Vector calculus is just the beginning my friend, you'll be needing to take probably 5 different types of calculus.





Most of the time a computer sciences or computer engineering 4 year degree will cover all you need to know.





2. A decent programmer starts out at about 50k/year. An expert is around 90k/year. Lead programmers earn usually 100k/year salaries, ones in big companies.


The poor quality ones are usually left at grunt level work at entry level salaries





3. It is a growing demand, with growing competition. If you are good, you will get the job. That's all I have to say.





4. Yes, you need to learn C++. Game programming REQUIRES C++, you wouldn't be able to even think about taking such a class without C++ knowledge.





It sounds like you are just picking and choosing courses. Bad idea.





Take a 4 year college degree in either Computer Sciences or Computer Engineering. You'll learn all you need to learn about programming from there, and you'll be better exposed to game elements if the school has a game design club.

Camcorders, what does this all mean?

My husband and I just received out tax refund and one of the things we need to get with it is a new Camcorder. We just had our first baby and I rely don't want to miss his first steps and all those other things... The only problem is I have been kinda out of touch with technology lately so I have no idea what all this crap means anymore!





Suddenly I'm looking at a huge list of stuff like Recording Formats like HDV, HDD, Mini DV, Hi-8, MD Digital, S-VHS-C, S-VHS, DV, Micro MV, VHS-C, Digital-8, Flash Media, Blu-ray, ect...


Recording Speeds, Image Stabilizers, MPEG Movie Mode Resolutions, Memory Card Types, Output and Imput Interfaces...





Saying to myself WTF is all this and what the heck does it mean. I googled it and read some stuff but wiki and these other sites speak a different language sometimes to me. They assume I'm all hight tech and leave me scratching my head looking dumb...





The last thing I rely want is to go into the store and know nothing. I was a salesmen...

Camcorders, what does this all mean?
It sounds as though you don't want to spend very much for anything you won't understand how to use. In this case, I would recommend either Mini-DV or Flash Media. In general stay away from things like Hi-8 and Blu-ray because they really can be difficult to work with.





Mini-DV stands for Mini-Digital Video. It records onto a small tape that you put in the camera. It is good for simplicity, reliability, and video quality. Generally you can record about 60 minutes on one tape. When you want to put the video on your computer or a DVD, you hook the camera to the computer with a cable and use a special program to import the video. Usually a program for this comes with the camera. Then you can use a program (sometimes the same program) to edit it if you want and burn it to a DVD that you can then stick into a DVD player and watch on the big screen!





Flash Media just means the camera records onto a small flash stick, like those usb sticks or "flash drives" you always see. This format is a little more complicated than mini-dv, because it depends on what kind of flash stick you use. For instance, there are memory sticks, sd cards, compact flash, etc. I wouldn't recommend this format unless you are willing to dive into all this.





It also sounds as though you don't have any idea where to start looking in terms of companies and models. Here is where I can help you. For Mini-DV cameras I can highly recommend the Panasonic PV-GS320. I own the slightly higher end version of this, the PV-GS300, and can attest to its ease of use and quality. Other than that I can recommend the Elura line of camcorders by Canon. They are pretty much made for people just like you who need ease of use and simplicity. They are very popular.





All that other stuff you mentioned like recording speeds, image stabilizers, mpeg movie mode resolutions, bla bla bla... You really don't need to worry about any of that except for image stabilizers. Image stabilizers simply stabilize the image that is being recorded to the tape or flash stick or whatever. In other words, they take most of the natural hand shake out of the video. All cameras have some kind, whether it's Electronic of Optical. Optical is superior to Electronic, but usually means you pay more too. So it's up to you.





People make a big deal out of HD (high definition) these days. You really don't need to worry about it. SD (standard definition) works just as well. If you don't have an HDTV you won't see it anyway.





I hope I didn't confuse you more. I'm more into the higher end of the camcorder thing, like the ones they use on movie sets for big productions.





Google is a wonderful resource for this too. Here are a few links:

Vb 2008 learning help ?

since i am using computer from 5 to 6 years.i have good command over computers internet etc. now i want to start to learn programming from basic to advance. i dont have any knowledge of language fundamentals. i have seen VB 2008 i have designed some basic interfaces in it. but later i came to know that i must have good concept of OOPS or C or c++. few told me you cant learn VB2008 without learning vb 6 or Vb .net 2003. if i will start learning that it will take 6 or more months and than VB2008. its not look great for me. i dont want develop hardcore giant and multinetwork applications. i am planning to develop midrange of applications relating to inventory accounts etc. my question is


it is possible to learn directly VB 2008 or i have to learn vb 6 and more. i always wonder how can u lern writing lots of codes betwen the lines. guide me in this more suggetions also.

Vb 2008 learning help ?
VB 2008 would be a great starting place. VB6 is not, 2008 is more tuned towards object oriented programming. You can dive right into this stuff, I did. You'll find that if you learn 2008, you'll be able to understand most of VB6, and possibly some of C and C++. The underlying philosophy of most computer languages are the same, so pick one that's pretty easy (VB is a great choice) and that is going to be a valuable skill for your future.
Reply:You can start learning it directly without the need of learning 6.0 and other versions. Take my example, i'm a vb 2005 hobbyist who didnt start from 6.0 or 2003.The best way to learn vb2008 is the video tutorials from the microsoft site from where you download vb. It's 100% beginner friendly. I truly recommend it.

from where to begin ?

Vb 2008 leaning guide?
If you are a beginner, the best place to start is reading a book called:





"Visual Basic 2005 step by step".


Although this book is about VB 2005, VB 2008 is the same.





Here is the download link:

By the way, Microsoft also provides online tutorials.

HELP me OUT!!?

I need advice.. quick!


I have got a simple circuit to control an LED via the parallel port (thru a Turbo C 3.0 program) but i somehow cant manage it...!





the outportb(PORT, value) command doesnt seem to work!!





i connected the +ve leg of the LED to the D5 connector and the -ve leg to the ground (hole 18) of the parallel port... used the outportb() function but nothing happened!!!





what could be the problem? am i connecting the LED in a wrong way??





PS: ALSO LEMME KNOW OF SOME COOL PARALLEL PORT INTERFACING PROGRAMS USING TC 3.0!!! I'M A STUDENT OF BS

HELP me OUT!!?
Ok, as for the harware connections on a parallel port, I've got no clue. However, TC3.0 is a DOS version, if I remember correctly. You don't say what os you're trying to run the program under, either. So, given that here are potential problems I see for the program.





1). Trying to run a DOS port control program under Windows. This is almost invariably a problem someone will hit these days. In Win9x, this isn't usually a problem. In any Windows Someflavor other than that, Windows wants your program to know the secret handshake before it will give up the hardware to your program's control. Quick Dirty Fix: Use DOS from MS-DOS or Win9x on a bootable diskette to run your software.





2). You're not sending the right value to the parallel port to make the LED work. The value doesn't set the bit that the +pin is connected to. Change the value so it does!





3). You've got everything working, but the LED isn't lighting. Well either it's A. the LED isn't any good (test it!) or B. the pulse width coming from the parallel port isn't wide enough to light the LED for an observable time. Send more pulses coming fast and see what happens.





4). Re-check all standard parameters, like the port number of the LPT one final time and cross all fingers and toes!





5). If all else has failed and you suspect the code is at fault, then try the URL below for examples.








This is what I know from experience in programming communications ports and what little electronics I know. I hope you find your answer here. Good luck!

Unable to uninstall PCTools Antivirus?

I've had this program for about a year. I installed the Vista SP1 and suddenly have problems. Tried to restore to before SP1 but the restore hung on the Registry for 4 hours till I finally shut it down and rebooted to the latest good boot through Safe Mode. So, now my problem with PCTools antivirus is that I can't get into it AT ALL to stop it and I can't uninstall it unless I do (wanted to install a different antivirus). In process of trying, I've run across all sorts of errors and PCTools won't help at all since it's a free version. These are some of the things I've done/seen while working on this:





1) Removed it from the startup menu - but it's still running





2) Installed newest version hoping that it would overwrite the old and I would be able to get into it. Well, I could but the old version was still running! And I could not get online anymore. After an hour on phone with my IP who told me he could see my modem, I restored back to before I installed new version. Could get onliine but get the following messages every time I startup:





Message Title: Microsoft Visual C++ Runtime Library


Program Path: C\Program Files\PCTools Antivirus\PCTAVSvc.exe

This was followed by:





Runtime Error!

This application has requested Runtime to terminate it in an unusual way. Contact the application support team.





3) At one point, I opened a text file from PCTools and found this:

I don't know what to do nor do I know if my computer is being protected anymore. I've gotten various error codes and have gone to the PCTools site to see what to do about it but every time I have to uninstall the program to perform the fix and I can't uninstall it! The one suggestion PCTools gave me was to go to Safe Mode and uninstall it but that doesn't work either. Everytime I try to uninstall it I get an error that says I can't because it's running.

Unable to uninstall PCTools Antivirus?
Use ForceUninstaller(c) it reads the log from when the file was first installed and everywhere it was installed to and undo's those changes then removes the files

Apply functional decomposition in this project?

A text file contains the names of the students and their scores. Write an interactive program that does the followings: 1. Displays a menu list that has five options a.Getting the total number of students; b.Getting the average scores; c. Getting the highest score and the student's name; d. Getting the lowest score and the student's name; e. List the names and scores with the descending order of the scores. f. Quit. 2. Once the user picks one option except option f, the program should display the appropriate information first , then once the user types any key stroke, the menu should reappear. If the users choose option f, then the program terminates.Apply functional decomposition in this project. Specify the function interfaces in the source code. No global variables are allowed.

Apply functional decomposition in this project?
Functional decomposition in this context refers to breaking the program down into various functions - for example, a function for the menu, a function for option a, another function for b, etc. The alternative would be (if you were using C) to write the entire program in the main function.





Writing an entire program in one function would technically be valid, but the code would not be too readable to someone else, or even yourself after a few days/weeks/years so leads to difficulties in maintaining the software if a new feature needs to be added, or a bug is discovered.

This is a little hard to draw without monospaced text, so I'll try to describe it.





At the top layer is your box for interfaceA, which has method1.





On the second layer you'll have two boxes - one for classA, another for classB. I think the "implements" arrow is a dashed line with a not-filled-in arrowhead. Also off to the side you'll have ClassC, with a normal line, no arrowhead, connecting it to ClassB (since classB has private ClassC a).





On the bottom layer you'll have classD with the "extends" arrow - which I think is a normal line with a filled in arrowhead, pointing to classB.





And when things are called like "vehicle" "car" "boat" "driver" and "sports car" it all makes a whole lot more sense than classA classB and classC :)

parallel port interfacing or operating system (with focus on device driver recognition) projects are preferred..!

I think you should look around on sourceforge.net for something that addresses what you're looking for
Reply:anything dealing with robotics with a twist of AI. controling a robot (or some other machine) via usb would be cool. wireless device driver recognition would be off that hook (i.e. bluetooth)

Programming?

I'm new to C and C++ programming and I've learn them through books and online tutorials. But all the tutorials I've encountered only provide lessons that teaches us how to take inputs from the keyboard. Is there anyway to write a program that takes input from other I/O interfaces such as serial ports, parallel ports or usb? What are the knowledge that I need and the steps on learning that? I would be very grateful if anyone could provide me some links of the tutorials. Thank you very much.

For reading input from usb ,etc you need to use driver apis. Not that easy.

Help on College?
Almost any 4 year college or university will require you to take a core curriculum that includes science, foreign language, history, English, and a number of elective courses. These courses are required of everyone pursuing a BA, BS etc. However depending on your major and the college that you are in at your particular institution the requirements may be different. Plan on at the bare minimum having to take at least 2 semesters of English/Composition, Social Sciences etc. You may be able to take courses closely connected to your major or mathematics with your elective hours, but you will definitely have to complete the other core requirements to graduate.
Reply:You certainly sound like you're going to be unusually well-prepared. However, as for that course, did you notice at the bottom of the page describing it, for prerequisites it lists "Senior standing"? In other words, this class is for college seniors. There's years of CS courses that are required, too.





As for all the other courses you have to take: Yes, check out the web page I cite below. It lists a lot of other things, English, history, liberal arts, all of that stuff. However, those are requirements only if you wish to get a degree (which I highly recommend). If all you want to do is take the CS and Math stuff, then I'm sure UNR is like every other university and will let you take stuff as a "townie", that is, take courses just because you're interested in the topic. You'd still have to convince the teacher that you're qualified. And usually any credits you earn in this way will not be allowed to apply towards a degree requirements if you later change your mind about getting one.





I'd advise you to get a good education. Who knows how things will be a decade from now. A lot of programming jobs are, and will continue, disappearing to India, Russia, and elsewhere. If that's all you know how to do, you may be really screwed in the future.


Programming advise?

since i am using computer from 5 to 6 years.i have good command over computers internet etc. now i want to start to learn programming from basic to advance. i dont have any knowledge of language fundamentals. i have seen VB 2005 i have designed some basic interfaces in it. but later i came to know that i must have good concept of OOPS or C or c++. few told me you cant learn VB2005 without learning vb 6 or Vb .net 2003. if i will start learning that it will take 6 or more months and than VB2005. its not look great for me. i dont want develop hardcore giant and multinetwork applications. i am planning to develop midrange of applications relating to inventory accounts etc. my question is


it is possible to learn directly VB 2005 or i have to learn vb 6 and more. i always wonder how can u lern writing lots of codes betwen the lines. guide me in this more suggetions also.

Programming advise?
to learn visual basic 2005 or later without visual basic 6 knowledge, you must have a project in mind.





and good housekeeping of files, good utilities to troubleshoot the codes, good backup of files, lots of rest after thinking about the codes etc.





to master the basic knowledge of visual basic 2005 or later, you need at least 6 months or more unless you have a teacher beside you.





work hard and you can make it to the programmer's desk.

How do I create an ObjectDock docklet?

WinCustomize's website sucks (I can't believe they actually try to sell subscriptions for that crap) and I can't find anything on how to create an ObjectDock docklet. I know that it has to be an old API-style DLL, which I can write in C++, but I can't find any documentation on what functions I need to write! And I can't search worth crap on that worthless website.





Can anyone help? Does anyone know? I'm trying to write a proxy docklet that will allow .Net programmers to create docklets by implementing a .Net interface. I know there's already something like that written by Littleboy, but it doesn't work. Please, someone, point me in the right direction?

Places with the strictest gun control also have higher crime rates, look at New York City and Washington D.C. I had a dear friend killed at Virginia Tech on 4/16/2007 and I am not in favor of strict gun control. I like knowing I can defend myself from intruders to my home as opposed to waiting for a cop to show up and possibly being too late.
Reply:I have nothing against citizens bearing arms - that is a right guaranteed by the constitution. I do think that there needs to be some greater method of background research done before someone is allowed to get one, and there needs to be stiffer responsibilities for those that allow a weapon to be sold/obtained by someone that was found to legally not be fit to possess a weapon. If someone bypasses the system and gives a person a gun that didn't pass the background check, only for the gun to be used in a murder, then the seller should also be on trial for murder. Sellers need to be as responsible as the users of the guns.





I personally don't agree with a gun being more protection - it has been proven that individuals that have guns for protection are more likely to die during the commition of a crime against them than those without. That speaks way too much to me. And I have a 2 year old that is extremely curious and crafty - I would be too afraid for her safety having a gun in the house. But I am lucky to live in a country where that is MY choice - not something that I am forced to do.

questions -


A ) some mentioned it has 2 pixel piplines so i asked xfx help desk 3 times . they replied it has 4 pipelines as far as they know !! they make it .. what is as far as they know mean ?


B ) can a same chipset shipped by NVidia ( in this case 6200 ) have pipelines shut of by vendor ( XFX ) ?


C ) can one trust Nvidia/ATI ?

Nvidia chipset pipeline confusion ... ?
A. it depends on how the manufacturer makes it, 2 pixel pipelines is REALLY outdated these days.


B. Yes.


C. Yes (my video card is from Nvidia)
Reply:Remember that the GeForce 6200 and the GeForce 6200LE are DIFFERENT video cards, in which in your ase, the 6200 has 4 pixel pipelines and the 6200LE has TWO pixel pipelines.





If I remember correctly, yes they can. I remember that there is actually no 6200LE reference board made by NVidia, it was simply made by the third party manufacturers.





Yes, I trust them both. But since they're both business, they do some sort of sneaky practices here and then.
Reply:Maybe you or help desk is referring to different item.





I don't see why they want to do that.





Sure.

How do I configure 2 Hard Drives?

1 Hard Drive


-- Seagate Barracuda


-- 7,200 rpm / 250 gig


-- ST3250823AS p/n for the hard drive








I just bought a 2nd hard drive





Specs


Western Digital -Raptor X


Model WD1500AHFD


Interface SATA 1.5Gb/s - 150GB


RPM 10,000 - Cache 16MB





I have plenty of sata ports on my mobo and physical connection of hard drive is straightforward.








What is the best path to follow so the Raptor hard drive(new one) becomes my C: drive(Operating system on this) and the Seagate(original one) becomes the D:





thanks

How do I configure 2 Hard Drives?
As I understand you dont want to keep your current operating system, because you already said you can reinstall windows again. well so now you just need to make some changing in your hard drive jumpers, have a close look of your both hard drives in bottom area you can easily found jumpers, set the jumper of your 1st Raptor hard drive as Master and other slave to other one. now confirm that your both drives are working together correctly? if positive then boot your system with your operating system CD and go on, complete your windows installation. if you have any kinda problem then just remove your segate one and leave your Raptor drive now install your OP again, after when your system has been installed completely plug your segate drive. good luck
Reply:You can copy old drive to new drive and then erase old drive and reformatt to be empty.Then just switch sata cables.
Reply:Personally, I'd keep the Seagate as the primary drive, since they're more reliable than Western Digitals, but if you want to make the migration without going through the process of installing OS and applications from scratch on the new drive, invest in a copy of Norton Ghost. Ghost your old drive to your new one, change your boot priorities in the BIOS and then reformat the old drive.
Reply:Your final choice would be best. Install the new drive only, reinstall a new O/S, then add the old drive as a slave. It will automatically be renamed "D" drive when you reinstall. Delete the O/S off the original drive or it may cause problems. Nothing should be lost, but might want to back up first.

How to Hook Windows API?
Look up spawn functions. I have used following.





strcpy(thisProgram, "OneWin.exe");


spawnl(P_WAIT, thisProgram, thisProgram, runParameters, NULL);





You can only only control other programs if they have input parameters.
Reply:I have been working with some API stuff lately myself, and I think if you enter the name of the app you want to interface with, and 'API' afterwards, you will probably find what you are looking for. You may also want to enter the letters 'SDK' after the name, as sometimes the guides to the API's for products are included in the SDK's. The 'Win32 API' is the main one to check out for Windows related stuff. For Yahoo Messenger, you might type something like


"Yahoo Messenger API SDK" into a search engine.

hey mate,





firstly i dont know if you are experienced with PCs but all i can say is unless you are very experienced NEVER alter your C//WINDOWS folder ...trust me bad things can happen ..





ok what you need to do is really quite simple:





google 'free website blocker' there will more than likely be some kind of software option there for you. once youve found some software that you like the sound of, download it and press 'RUN'. most of these programs will be able to block websites based on keywords, searchs, URL, and basically any other way you can think...





and best of all most of these prograsm will be less than 5 megabytes so it wont affect your PC harddrive size availaible..





hope this helps mate,,





peace
Reply:You Click the start button, then Control Panel, Then click Internet Options, Click on the Security Tab now you will see 4 icons one of those icons is red with a line in the middle called Restricted Sites Click on that once so that it is highlighted then click Sites now add the site(s) that you want to ban.
Reply:you can use third party software like NetDog : http://www.netdogsoft.com , it's easy,, just add website to "Always blocked website list" in NetDogAdmin.exe, none will be able to open it.

TORQUE of disks!!!!!?

Three flat disks (of the same radius) that can rotate about their centers like merry-go-rounds. Each disk consists of the same two materials, one denser than the other (density is mass per unit volume). In disks 1 and 3, the denser material forms the outer half of the disk area. In disk 2, it forms the inner half of the disk area. Forces with identical magnitudes are applied tangentially to the disks, at the outer edge of disks 1 and 2 and at the interface of the two materials for disk 3





(a) Rank the disks according to the torque about the disk center, greatest first (use only the symbols %26gt; or =, for example, 1=2%26gt;3).


(b) Rank the disks according to the rotational inertia about the disk center, greatest first (use only the symbols %26gt; or =, for example, 1=2%26gt;3).


(c) Rank the disks according to the angular acceleration of the disk, greatest first (use only the symbols %26gt; or =, for example, 1=2%26gt;3).

TORQUE of disks!!!!!?
Torque is defined as the product of tangential force and the dist. of its application point from the centre, so it is in the same ratio as the latter


(a) 1=2%26gt;3


The rotational inertia of disk two will be least because the denser material is closer to the centre so


(b) 1=3%26gt;2


we know, Torque = Moment of Inertia * Ang. acceleration.


so α = T / I


Torque of 1 and 3 are in the ratio √2 and their I are equal. so α for 1 is lesser. Also T for 1 and 2 is equal and I for 1 is higher so α for 1 is less. But the relation between 3 and 2 cannot be said until the relation between the densities of the materials is not provided. we can only say that


(c) 3%26gt;1%26lt;2


Refraction?

Three sheets of plastic have unknown indices of refraction. Sheet 1 is placed on top of sheet 2, and a laser beam is directed onto the sheets from above so that it strikes the interface at an angle of 26.8° with the normal. The refracted beam in sheet 2 makes an angle of 30.6° with the normal. The experiment is repeated with sheet 3 on top of sheet 2, and with the same angle of incidence, the refracted beam makes an angle of 37.3° with the normal. If the experiment is repeated again with sheet 1 on top of sheet 3, what is the expected angle of refraction in sheet 3? Assume the same angle of incidence.





I've tried 57.1 degrees on my webassign and it is wrong. Any help is appreciated b/c I don't know what to do on this problem anymore. Thanks.

Refraction?
Here's the way I would do the problem:





From experiment 1 (sheet 1/sheet 2) we know that:


n1 * sin(26.8) = n2 * sin (30.6)





From experiment 2 (sheet 3/sheet 2) we know that


n3 * sin(26.8) = n2 * sin(37.3)





The equation for the experiment in question is


n1 * sin(26.8) = n3 * sin θ


and we want to solve for θ.





From the first two equations we have that


n1/n3 = sin(30.6)/sin(37.3)





Plugging this into the equation we are trying to solve we get


sin(30.6)/sin(37.3)*sin(26.8) = sin θ


θ = arcsin (sin(30.6)/sin(37.3)*sin(26.8))


θ = 22.256 degrees
Reply:Wow this is a great question. I'm no help. I thought that the angle of incidence equaled the angle of reflection, so all angles are equal unless they are not exactly parallel. I'm confused.


Could I defragment my hard disc even though Gateway formatted my new hard disc backwards?

o.k where to start! I am on second p.c from gateway w/vista this year.I have had problems with aol not responding and losing connection constantly.Plus numerous other handy little problems.I wound up getting a new hard drive 1 month after purchase because I tryed to do a factory re install after all the little problems. The re install caused me to lose my boot manager and I had no recovery period .So they send me a new hard drive partitioned backwards" yea that is what I said"!I have 0 recovery partition now.I am wondering can I defragment my hard disc,if it is formatted backwards already?Yea I know crazy.This is only a portion of the story.Not to mention the fact that my atm interface "made by gateway"isnt vista combatible neither is intel active management.And they wont help me substitute them they just say uninstall vista.I bought the comp with vista folks!!My advice buy a hp.

Could I defragment my hard disc even though Gateway formatted my new hard disc backwards?
yes
Reply:In your opinion its backwards. Can you access files ? Can you save files ?





If so, its not hardward backwards.





Give defrag a try.





On your recover partition, is it hidden ? Give it a try by hitting F8 when you boot and see if there is a recovery option. I'm not saying go back to Factory Settings ( unless you messed up one time (like me)) but see if it's there.

Question about adding a 2nd drive and making it the primary?

Current configuration


--------------------------------------...


Sony Vaio desktop


P4 3.0 512mb


win xp sp 2


1 Hard Drive


-- Seagate Barracuda


-- 7,200 rpm / 250 gig


-- ST3250823AS p/n for the hard drive








I just bought a 2nd hard drive





Specs


Western Digital -Raptor X


Model WD1500AHFD


Interface SATA 1.5Gb/s - 150GB


RPM 10,000 - Cache 16MB





I have plenty of sata ports on my mobo and physical connection of hard drive is straightforward.








What is the best path to follow so the Raptor hard drive(new one) becomes my C: drive(Operating system on this) and the Seagate(original one) becomes the D:





thanks


40 minutes ago - 3 days left to answer.


Additional Details


37 minutes ago





can i


1) remove existing seagate drive


2) install raptor drive in its place


3) do a fresh install of operating system


4) then after o/s and drivers are loaded on the raptor, then hook up the 2nd drive





Will I have to reformat the 2nd drive if i shift it from C: to D:?

Question about adding a 2nd drive and making it the primary?
The easiest way to do this is:





1. Remove old hard drive.


2. Install the Raptor and install Windows on it.


3. After Windows has been installed and stable, connect the second hard drive.


4. Make sure that the Raptor is the first boot device in the BIOS.


5. The old drive should show up as the next drive letter after C: and all of your optical drives - you can change drive letters in Computer Management.





You don't need to format the old drive. It will show up as a second hard drive.


World of Warcraft Help!!!- Need very experienced players/computer users?

Hello all. I play a popular online MMORPG called World of Warcraft. I am recieving a message that states that I am experiencing a WoW Error (a W.orld o.f W.arcraft Error). This is the message I am recieving...





This application has encountered a critical error:





ERROR #134 (0x85100086) Fatal Condition


Program: C:\Program Files\World of Warcraft\WoW.exe





Failed to open archive interface.MPQ: The system cannot find the file specified.











Now when i attempt to WoW repair it states that WoW is ''seriously damaged and will need to be reverted to an earlier version''. When i click okay it then states that ''the amount of data required to repair World of Warcraft is too large.'' then it says ''Please reinstall. ''


When i try to uninstall it says '' Sorry, uninstallation failed ''Uninstall.xml'' could not be read ''








Any help would be GREATLY appreciated.








Best Regards,

Reply:Dude WTF u dont have to reinstall...That happens to me all the time its just blizzard tryin to mess with ur mind nothins wrong its just blizzzard SUCKS just wow is good sometimes... Report It

Reply:do you have the cd rom becuase if u download it on the computer they're more risk of errors since it downloads from internet if u dont hav cd rom buy it and try Report It

Reply:Actually the best thing to do would be to go to Program files go to your WOW folder open it...then right inside there is a repair program that will run and make sure all the files are there. Report It

Reply:Til around level 12, stick to your starting zone doing all the quests there, the quests will eventually be gone in that zone, and towards the end of the quests, you will get one that moves you onto the next zone.





As far as money is concerned, noone likes beggars, I'd suggest not begging for money on your realm as it will give you a bad rep fast, lots of ignores, and if you plan on playing that character all the way to 70, later on you might find that noone will want to instance with ya because they think you are greedy and might even have you on ignore already. Besides, asking for gold on the forums is worthless anyways, there are hundreds of servers in wow which are not connected to each other, and chances of finding someone from your server on your faction who is willing to give someone gold for nothing is very slim.





Just quest, fastest way to level in the game, and the higher level you get, the more gold you will get.

Reply:did you try deleting the wtf file of wow? that worked for me.
Reply:Yes, you will probably have to delete physically the wow folder. Enter my computer, go to program files and delete the wow folder. You can also try deleting the file by going to the control panel, add/remove program and remove wow.


If not, you should call or write to the wow staff.
Reply:WOW!!! that sounds pretty bad %26gt;.%26lt; that happened to me before but only once i dunno what to do sorry :(
Reply:You have to completely Uninstall World of Warcraft NOT DELTETE Uninstall it then turn off your computer and reinstall it so that the files are new to it and dont move your mods or certain files out to save Download time you have to Uninstall the whole thing and then reupdate it for it to be fixed
Reply:This has happened to me before and what you will need to do is go into your your program files under "my computer" and physically delete all world of warcraft files. You could also ask the tech department on their website they emailed me detailed instructions on how to do it.( I am no expert on computers so you might want to get the info from them since it been awhile that had to do this)

Bt home hub network attached storage?

hi there


is there a way i can attach a external hard drive or even a spare p.c to my home hub and then use it as a network attached storage device


however i am currently using both the ethernet connections on the hub so i would have to use the spare usb connection,but i suppose i could allways swap the p.c next to the hub to a usb connection giving me a spare ethernet connection


if you can then can you recommned some software that has a easy to use interface,so it can used by anyone


cheers guys !

Bt home hub network attached storage?
Get a cheap 5 port switch and this should solve your problem, best go for a NAS type drive so it become an network drive rather than one that needs a PC to work.
Reply:You could buy a 4 port switch. Connect the switch to the hub via one of the Ethernet cables - now connect up to 4 computers to the switch via Ethernet.





Here is an example with 5 ports - will be fine:

Easy programming language - more detail on what for inside.?

I am an estate agent and have used basic text programming before like on the mac i know how powerful thsi is when used to its full potential but requires a lot of work. I dont mind the work but what i want is programming software which i can link up with word and works and a database to do automated mailshots, search relevant information etc. the actual structure would be fairly simple and the interface would be very basic. I would even drop the word, works and database if the program could act as a database and word program. Would need to be fairly simple to create. I have an advanced higher in computer programming but never took it further at school so i do know roughly about design, implement and testing etc. I have got C++ but i think you would need a degree just in C++ to have any clue abotu it. Its not very user friendly.

Python. Very powerful, easy to lean and use, doesn't get in your way, can interface with any database.

Interface: Ultra ATA-100





Spindle Speed (RPM): 7200





Buffer Memory: 16MB





Average Latency (msec): 4.16





Maximum External Transfer Rate (Mbits/sec): 100





Temperature, Operating (°C): 0 to 60





Temperature, Nonoperating (°C): -40 to 70

Visual basic 2005 help?

since i am using computer from 5 to 6 years.i have good command over computers internet etc. now i want to start to learn programming from basic to advance. i dont have any knowledge of language fundamentals. i have seen VB 2005 i have designed some basic interfaces in it. but later i came to know that i must have good concept of OOPS or C or c++. few told me you cant learn VB2005 without learning vb 6 or Vb .net 2003. if i will start learning that it will take 6 or more months and than VB2005. its not look great for me. i dont want develop hardcore giant and multinetwork applications. i am planning to develop midrange of applications relating to inventory accounts etc. my question is


it is possible to learn directly VB 2005 or i have to learn vb 6 and more. guide me in this more suggetions also.

Visual basic 2005 help?
If you go to microsoft.com and search for VB 2005 you will find tons of links that will give you the options to learn from the pro's, some will offer sample code and some will offer instruction video, and for those that told you you need to learn the others first they are crazy, VB 2005 is the best and easiest of the bunch, it might take you some time surfing the links to find what you want but its there, good luck to you
Reply:You can learn vb2005 without previously learning vb.net 2003 and vb6.0. Send me an email to sumpersun@yahoo.co.uk and might be able to help you with some ebooks.

}

{


System.out.printf( "the discount is" ,c );


}


}


}


my question is how to make the answer for the second if statement the other method (ComputeDiscount)

I need help in java ((please))?
I notice you have a number of problems.





1) You cannot check if two strings are equal to each other with == you need to use string1.equals(string2). Since strings are objects the double equals sign will compare the memory addresses.





2) You're not using printf correctly (although the code will still run). To print doubles in a printf you need to put %d in place of where the number will be inserted the way you have it no numbers will be printed.





3) A variable declared in a method only exists within that method. So where you use 'n' in DisplayDiscount and 'a','b', and 'c' in ComputeDiscount, you're trying to use variables that do not exist within those methods.





4) In DisplayDiscount your if statements wouldn't make sense even if == could check equality for Strings. Notice that you have this line of code


if(d == "saturday" %26amp;%26amp; d == "sunday")


but it is impossible for a string to be both saturday and sunday. What you need to do is use OR instead of AND so the code should look like


if(d.equalsIgnoreCase("saturday") || d.equalsIgnoreCase("sunday")





5)ComputeDiscount does not return a value so in the code where you have printf("",ComputeDiscount). Even after you change the printf to include a number and add parenthesis with a value to ComputeDiscount so that it looks like this printf("%d",ComputeDiscount(3)) it still will have no value to print.





6)This is more of a style issue and your code will run just as well without it but the Java naming conventions say that method names should start with a lower case letter so it should be computeDiscount(double n) and displayDiscount(String d)
