Free software that allows me to set 2 desktop images for my 2 monitors

Normally I use DisplayFusion or UltraMon, but those programs are a bit overkill. At least I can use the free version of DisplayFusion. But I was wondering if there is a program that simply detects the screensize, allows me to pick two images and chose to fill or expand or tile, combines the pictures into one (while taking the relative position of the monitors into account) and creates a new desktopimage (and sets it).

QBASIC programs for finding n prime numbers

After I saw an article Prime numbers in wikipedia, I got that there is no formula for prime numbers. But in the QBASIC there are some programs for finding n prime numbers. Can't we use modified form of it in finding general term(formula) of prime numbers in real life mathematics? sahil shrestha 14:45, 19 June 2016 (UTC) — Preceding unsigned comment added by Sahil shrestha (talk • contribs)

Where you put them, at the top, they'd likely be missed by other user and not answered. -- Finlay McWalter··–·Talk 17:44, 19 June 2016 (UTC)[reply]

There are many algorithms for generating prime numbers. Some one of those algorithms is used by the QBASIC program you saw. When we say there is "no formula" for prime numbers, this means there is no way of directly computing, say, the 1000th prime number. The only thing you can do is run a prime number generation algorithm and throw away the first 999 numbers it generates. (You will find that the 1000th is 7919.) --Steve Summit (talk) 19:30, 19 June 2016 (UTC)[reply]

@Sahil shrestha:@Sahil shrestha:, Check out this -

FOR n = 2 TO 100
FOR k = 2 TO n / 2
flag = 0
r = n MOD k
IF r = 0 THEN
flag = 1
EXIT FOR
END IF
NEXT k
IF flag = 0 THEN PRINT n,
NEXT n

— Preceding unsigned comment added by Aryan hindustan (talk • contribs)

There are actually faster algorithms to find the nth prime for large n than to compute all the smaller primes but the basic point stands: There is no known efficient way to do it. The faster algorithms only means it becomes feasible (with a lot of computing power) for primes below 10²⁶ instead of 10¹⁹ or something like that. PrimeHunter (talk) 13:32, 20 June 2016 (UTC)[reply]

HTML form entry for money amount

I have the following code:

<p>Payment amount (USD): $<input type="number" size=10 maxlength=17 min="0.01" step="0.01" value = "1.00" name="amount"><br>

It works, but is a bit ugly, because while $1.23 shows up correctly, $1.20 shows up as $1.2 and $1.00 shows up as $1. How can I fix this ? StuRat (talk) 15:50, 19 June 2016 (UTC)[reply]

The quick answer is "with JavaScript" - you can't do it with the HTML alone. See, for example, this Stack Overflow thread. Tevildo (talk) 17:34, 19 June 2016 (UTC)[reply]

Well, that sucks, doesn't it ? I will just leave it poorly formatted rather than complicating things with more Javascript. Thanks for the answer. StuRat (talk) 15:11, 20 June 2016 (UTC)[reply]

HTML form entry for hidden numbers ?

Similar to the above, the type can be "number", in which case it is forced to be numeric, or "password", in which case it is not displayed, but replaced by asterisks. Is there a way to have both attributes, say for credit card numbers, which should both be forced to be numeric and hidden ? Or must we again use Javascript to do so ? StuRat (talk) 15:14, 20 June 2016 (UTC)[reply]

This is probably easier to do at the server end - leave the input type as "password", and check that the value is numeric as part of the form validation. But, yes, if you want to do it in the client, you'll need JavaScript. Tevildo (talk) 19:11, 20 June 2016 (UTC)[reply]

Thanks again. Looks like they need lots more capabilities in plain old HTML, to me. I wonder why it is still so basic, after all these years. StuRat (talk) 04:13, 21 June 2016 (UTC)[reply]

Pattern matching in functional languages

What makes this so special (according to FP adherents)? Couldn't this functionality be implemented in other languages easily? Like parsing an XML structure? There must be libraries for this in any language. --Hofhof (talk) 23:54, 19 June 2016 (UTC)[reply]

Well, in most languages (with the notable exception of the LISP family), libraries are very limited in what syntax they can use.

Here's a concrete example of a case where pattern matching is useful to make this clearer. In Python (and many other languages) if you look up a value in a map/dictionary and it isn't present, you get an exception (KeyError in Python's case). Python encourages you to use exception handling for this ("EAFP"). You can write

        try:
            ...  # do something with d[k]
        except KeyError:
            ...  # do something if k isn't in d

But that code is wrong if the thing you do with d[k] might also raise a KeyError. And even if it can't do that now, it might change in the future, so this pattern is fragile. You can't just move the code out of the try block, because code after the try block is run after the KeyError handler also. The only universally correct approach is

        try:
            x = d[k]
        except KeyError:
            ...  # do something if k isn't in d
        else:
            ...  # do something with x

This is now long and confusing, and still has the problem that if the except code throws an exception, Python will confusingly report the KeyError as the context for it, even though conceptually this is an if statement, and it doesn't do that for if statements. For all of these reasons, I often just write if k in d: ...d[k]... else: ... instead, despite its problems (code duplication and a potential race condition in threaded code).

In Haskell, you write

        case lookup k d of
          Nothing ->
            ...  -- do something if k isn't in d
          Just x ->
            ...  -- do something with x

This is the right syntactic structure for what I'm trying to do: it looks like an if statement, but it avoids a duplicate lookup by putting the result in x at the same time. The Nothing and Just clauses can be in either order (like the Python if statement, but unlike Python try, where except must precede else).

Introducing this kind of control-flow construct in a library would be difficult in most languages (except the LISP family). You would likely have to pass the patterns as strings (which would be parsed inefficiently at run time), and the code in the two clauses as anonymous in-line functions (if the language supports that). To bind x, you would probably have to name it in the function arguments and put the same name, or its numerical position, in the quoted pattern. You would need significant runtime reflection support in the language to make it all work. The patterns, being quoted, would not be correctly syntax highlighted. Since readability is a major advantage of this approach in the first place, it probably wouldn't be worth it.

For more complicated patterns, a library could be useful, even if it's string-based, as it could save writing a lot of code. Regexes are an example of that. I think the value of ML-style pattern matching is mostly in the simpler cases. -- BenRG (talk) 01:43, 20 June 2016 (UTC)[reply]

Win 7 keeps creating a new "My Documents" folder

When I first installed Win 7, I moved My documents to a separate physical hard drive and then renamed it as "Data" (I hate the twee names Microsoft uses). This was no problem but I keep getting a new My Documents folder created. It is created in the separate HDD where "Data" is located but it is called "My Documents". No matter how many times I delete this folder it just gets generated again. How can I persuade Win7 that my "Data" folder IS my "My documents" folder and stop it generating new ones?

Thanks, Gurumaister (talk) 14:31, 20 June 2016 (UTC)[reply]

On the "My Documents" folder, right click, choose "properties" and give it a new path. Windows will ask to move the files to the new path. --Hans Haase (有问题吗) 16:31, 20 June 2016 (UTC)[reply]

Virtual PC

Peeps, I don't know if this is too much of a botheration, I know it is, but here it goes.

My system info:

Windows 7 Ultimate Service Pack 1

Intel(R) Core(TM) i3-2350M CPU @ 2.30GHz 2.30GHz

8.0 GB (2.65 GB usuable)

32-bit Operating System

"Guidance"/"Link" received:

1) [1]

2) [2]

A) Press CTRL+F, than insert: Now, you can write the name for your new Virtual Machine and the location to store the virtual machine file. – On link "1".

The location of link (1) and (2) defines that I should use the OS name I’m planning to install, am I right? – I’m planning to install Window XP, Windows 7 Ultimate Service Pack 1, and Windows 10 Professional (64-bit). Btw, can I use 64-bit on a Virtual PC, of a 32-bit Original PC?

B) Press CTRL+F, than insert: In the next window, you can select the amount of RAM memory to assign to your virtual machine. – On link "1".

B1) How much MB should I select for Windows XP, Windows 7 Ultimate Service Pack 1, and for Windows 10 Professional (64-bit)? What do you guys suggest and could/should I/is it possible to insert the maximum for all three Operating System (OS)? – I don’t wish to ever look back in my life to perform this task again (to create the same OS Folders again), so, how much MB should I select for each OS?

B2) Is the networking Tick box option necessary? If it is unticked, will it create any problem with my internet usage of any kind, inside and outside (original PC) of my Virtual PC?

C) Press CTRL+F, than insert: As we selected the dynamically expanding virtual hard drive, we will specify the maximum storage space for it to grow in the next window. – On link "1".

C1) The above image of point (C), the Location is the same as the point (B), I’m putting all three OS on E drive, exactly; let me know if I’ll be facing any issues with the following.

C2) The image below point (C) specifies a maximum limit. What do you guys suggest and could/should I/is it possible to insert the maximum for each (all three OS)?

D) Press CTRL+F, than insert: Or select Open an ISO image to select an image with the installation files to install an operating system on your new virtual machine. – On link "1".

D1) I understand what Link "2" say and I’m guessing when I come to this stage I have to select the "Access a physical drive" feature. That being said, I’m planning to install all three OS via a "pendrive". The image above defined inside point (D) doesn’t display a USB port. If I keep my pendrive in, will it display when I’m at this stage?

D2) Press CTRL+F, than insert: Wait for the installation wizard to appear and follow the – On Link "2". - It say the installation will follow through as it does usually.

Q: Will it switch my PC off/reboot my PC when I install any of the OS? If so which one(s) will create this issue?

Apostle (talk) 19:17, 20 June 2016 (UTC)[reply]

It seems like you've mixed questions with instructions copied from elsewhere, and it's hard to tell which is which. I don't know what "Press CTRL+F, than insert" means either.

First, upgrade to 64-bit Windows. Product keys are the same for 32-bit and 64-bit editions, so you don't need to buy a new copy of Windows. As it is, only 2.65 GB of your 8 GB of RAM is being used; the rest is wasted. It's unlikely that Virtual PC will be able to use it either (it's not impossible but I doubt it). You will have a hard time running Windows virtual machines with less than 3 GB of total RAM.

After you've upgraded, I would probably allocate ~2GB of RAM to the VM (if you run one at a time). You can easily change that value later (you don't have to recreate the VM or reinstall the guest OS).

"The name for your new Virtual Machine" is for your reference; call them whatever you want.

Disk size doesn't matter much; choose 20GB or something unless you plan to install a ton of stuff on the guest drive.

If you start a VM with your thumb drive unplugged, then plug it in, it will most likely be connected to the guest (that's the default behavior), and you can then install Windows in the guest. If that doesn't work, look in the menus for a way to explicitly connect USB devices to the guest.

If you uncheck "network", the VM will probably be unable to access the Internet at all.

You will not need to reboot your host machine when installing any guest OS. -- BenRG (talk) 21:25, 20 June 2016 (UTC)[reply]

BenRG:I'm disallowed to upgrade cause I play rather than work

Yes I'm trying to install these OSs so that I can install all the softwares and all the games I have.

Sorry for the delay in getting back to you Ben. Btw, you have to press CTRL+F after entering in the links page guided in this post, in the web browser you are on.

Apostle (talk) 11:24, 22 June 2016 (UTC)[reply]

Don't understand what you mean by "play rather than work". Nowadays x64 compatibility even for games is rarely worse than x32. And there are a small number of games which require x64 or won't work so well under x32 (2GB of RAM can be limiting). Heck even 8 years ago things weren't that different (except games using more than 2GB was rare). As far as I know, there's no Windows licence for "play" which doesn't allow the installation of x32, Windows starter editions are long dead and in any case I believe even these allow the install of x64 versions and aren't really that suitable for most play or work and you indicated you have Ultimate anyway. If you look at something like the Steam survey, you find 84.63/95.42 Windows users are using some x64 [3]. Furthermore for those odd times where you do need a VM, you'll be far better of using a VM which works well because it has sufficient RAM and so does your main OS then you would where both are struggling. BTW, due to limitations around 3D hardware acceleration support, gaming even 8 year old games under VMs isn't always a pleasant experience. You're better of running as many games as you can under your native OS. In other words, all roads strongly suggest you're far better of running a x64 OS natively. If you mean this isn't a computer you administrate and whoever owns it doesn't want you playing games, well running them on a VM isn't particularly likely to please them either.

How do I get rid of Win7 update KB2952664?

I am running Win7 and most definitely do NOT want to install Windows 10. I also don't want those annoying reminders and persuaders for Windows 10 that Microsoft likes to install on my PC. For that reason, I now check all Windows updates before I install them and tell Windows to 'hide' any that are to do with upgrading to Windows 10.

I somehow seem to have installed update KB2952664 which is related to Windows 10. I have used the update uninstall facility to get rid of it and what happens is both interesting and very annoying: First, I uninstall it and it does, indeed, disappear from my list of installed updates. But, second, when I restart my PC, the update reappears on the list with today's date as its installation date. This is despite the fact that my update settings say that Windows should leave updates for me to install - and I have not reinstalled that update.

Can anyone tell me how I can get rid up KB1952664 and how I can stop it reinstalling automatically? Gurumaister (talk) 06:07, 22 June 2016 (UTC)[reply]

Windows folder view setting changes for no apparent reason

To give you a bit more info, one of the most basic ways goolge chooses if a search result should be "high" in the results is how many OTHER websites link to it. If you have dozens of different websites linking to your site, it will appear higher in the results. If you just made a stand alone site and no one else links to it, there very little you can do to your website to "force" google to make your result higher, using things like keywords.

ENIAC and an earlier computer

Milestones in Computer Science and Information Technology by Edwin O'Reilly says of ENIAC: "... a more accurate claim would be 'worlds first automatic, general-purpose, electronic, decimal, digital computer."

So what if "decimal" is omitted - what is an earlier automatic, general-purpose, electronic, non-decimal, digital computer? Bubba73 ^{You talkin' to me?} 23:47, 22 June 2016 (UTC)[reply]

There were many such earlier computers, the various mechanical computers designed by Charles Babbage and Ada Lovelace predate the ENIAC by over a century, for example. History of computing hardware is a good place to look for some more examples. --Jayron 32 23:52, 22 June 2016 (UTC)[reply]

Yes, but which one was automatic, general-purpose, electronic, and digital but not decimal? Bubba73 ^{You talkin' to me?} 00:49, 23 June 2016 (UTC)[reply]

If you accept electromechanical, the Z3 was automatic, general purpose and digital computer. However, it is also decimal, so isn't what you are looking for. The ABC wasn't programmable, so fails the general-purpose requirement. Which leaves us with Colossus as the only pre-ENIAC electronic computer left. It was electronic, digital, automatic and programmable. However, it used biquinary values to represent decimal numbers, so perhaps that is why it is precluded by O'Reilly. - Bilby (talk) 01:09, 23 June 2016 (UTC)[reply]

And Colossus was not a general-purpose computer. Bubba73 ^{You talkin' to me?} 01:14, 23 June 2016 (UTC)[reply]

The first automatic, general-purpose, electronic, digital, binary computer was the Manchester Baby, which post-dates ENIAC. See List of vacuum tube computers for the list in chronological order. Tevildo (talk) 19:00, 23 June 2016 (UTC)[reply]

I think (although this is just personal speculation), the "automatic" exclusion might play a part as well. ENIAC (despite the name) wasn't fully-automatic until September 1948 - before then, it was programmed with a plugboard, like Colossus. The Baby was automatic from the word go (June 1948), although ENIAC had run with manual programs before that date. Tevildo (talk) 19:15, 23 June 2016 (UTC)[reply]

I think that automatic referred to its operation. Once the plugboards were set, it would run on its own, unlike a calculator. Bubba73 ^{You talkin' to me?} 20:42, 23 June 2016 (UTC)[reply]

Colossus wasn't designed as general purpose, but it was arguably Turing complete, based on Wells. - Bilby (talk) 07:53, 24 June 2016 (UTC)[reply]

The Z3 used binary, not decimal. It had a 22-bit word length and represented floating-point numbers using 7 bits of exponent, 14 bits of mantissa, and a sign. (Thus, assuming the exponent was signed, it could represent values from approximately 10¹⁹ to 10⁻¹⁹), or their negatives, with approximately 4 decimal digits of significance.) --69.159.9.187 (talk) 22:41, 23 June 2016 (UTC)[reply]

But it was electromechanical, not electronic. Bubba73 ^{You talkin' to me?} 00:00, 24 June 2016 (UTC)[reply]

True. --69.159.9.187 (talk) 05:39, 24 June 2016 (UTC)[reply]

I was presuming by decimal that they used binary, but accepted decimal I/O. Z3 apparently had decimal input and output, but not operation. - Bilby (talk) 07:50, 24 June 2016 (UTC)[reply]

As far as I can tell, there was no was automatic, general-purpose, electronic, digital non-decimal computer before ENIAC. It looks like Edwin O'Reilly was wrong. Of course the article needs to follow the sources, not my original research... --Guy Macon (talk) 08:42, 24 June 2016 (UTC)[reply]

Landline telephone amplifiers?

I have a landline telephone setup (single line, nothing fancy) that doesn't get a great signal. I've tried to look online (Google, Bing) for a device that I could plug the line in (from network interface device) to and plug the house wiring into to get the amplified signal. Do they make things like this? If so, is there a name for them I'm missing? When I search for this I get cell phone products. I'm using United States style telephones and telephone wiring. Thanx. 104.229.143.192 (talk) 23:58, 23 June 2016 (UTC)[reply]

Because of the way telephones work, it is much easier to amplify the signal going to the handset instead of the signal from the wall to the phone. Here are some typical products:

You can also complain to the phone company and ask them to send louder audio. --Guy Macon (talk) 05:18, 24 June 2016 (UTC)[reply]

Many many years ago, I did a lot of audio-visual work, which included landline telephones (which were just called telephones at the time). I was asked to turn up the volume on phones many times. The problem always turned out to be static on the line, making it hard to hear the audio. So, the problem wasn't the audio volume, it was the static. Static on telephone lines is common. It can be a loose connection - which is an easy fix - or an old wire that has corroded - which requires rerunning new wires. Once I got rid of the static, the phone's volume was just fine. So, I wonder if this is truly a case of low phone audio or loud static. 199.15.144.250 (talk) 12:34, 24 June 2016 (UTC)[reply]

COM objects in C#

(To forestall the obvious comments - can we assume it's the year 2005 for the purposes of this question? Using more up-to-date tools is not an option. Thanks.)

In VB6, to instantiate a COM object and use one of its interfaces, we can do:

Dim oTemp As Object
Dim oRealObject As MyTypeLib.IMyInterface

Set oTemp = CreateObject("MyDll.CMyClass")

If TypeOf oTemp Is MyTypeLib.IMyInterface Then
    Set oRealObject = oTemp
    oRealObject.DoThings
Else
    MsgBox "MyDll.CMyClass does not support the IMyInterface interface!"
End If

In C#, we can do something similar:

Type comType = Type.GetTypeFromProgID("MyDll.CMyClass");
var instance = Activator.CreateInstance(comType);

if (somethingOrOther)   //  This is my question
{
    IMyInterface realObject = (IMyInterface)instance;
    realObject.DoThings();
}
else
{
    MessageBox.Show("MyDll.CMyClass does not support the IMyInterface interface!");
}

What should "somethingOrOther" be? comType.Equals(typeof(IMyInterface)) returns false, even though instance does in fact implement the IMyInterface interface (and the DoThings function works properly). Thanks in advance. Tevildo (talk) 14:41, 24 June 2016 (UTC)[reply]

You should use typeof(IMyInterface).IsAssignableFrom(typeof(comType)). (From here.) The reason that comType.Equals(typeof(IMyInterface)) returns false is because for simple equality comparison, comType does not equal IMyInterface. Type.IsAssignableFrom() uses more complex comparison. Fr∧m∈Dr∧g^talk 14:56, 24 June 2016 (UTC)[reply]
