The character ꞵ

What is this character? A search through Google tells me that it's "latin small letter beta" and points me to a French Wikipedia article, fr:Ꞵ, which uses it as its title. How is this different from the ordinary beta character, β? The voiced bilabial fricative article seems to distinguish between β and Ꞵ, saying that a certain sound can be transcribed β "or more properly Ꞵ", so I hesitate to redirect to Beta. Nyttend (talk) 03:49, 30 March 2016 (UTC)Reply

Interesting -- it seems to be used exclusively for some Bantu languages. Latin large letter beta appears to have a descender. I hope someone knows what this is about; I'm quite curious. --jpgordon::==( o ) 04:37, 30 March 2016 (UTC)Reply
It's already mentioned in the beta article, so I think it makes sense to redirect there. The proposal to add it to Unicode (which is linked from the French article) lists some uses and points out that it's likely to be rendered differently from Greek beta (more upright, and with a serif on the descender). Unicode has always distinguished letters of different scripts even if they look almost identical (like o, ο and о). -- BenRG (talk) 04:40, 30 March 2016 (UTC)Reply
Apparently it was added to Unicode in version 8.0. In the relevant code chart, it's in a section titled "Letters for African languages" --69.159.61.172 (talk) 08:18, 30 March 2016 (UTC)Reply

Please recommend hardware.

I have this rack mount R5400 Dell machine and my internal hard drive crashed. Now the data is recovered but I need to purchase a new drive. I want a 15,000 rpm, 3.5" (the old one was a VelociRaptor 10,000 rpm). Could anybody recommend something that will work for me a long time?

How big is the drive that you want?--Phil Holmes (talk) 11:07, 31 March 2016 (UTC)Reply

300 GB.

HGST IDK Deskstar 3.5 inch 3TB Internal Hard Drive looks like a good choise. Some stat's are here: [1]. VelociRaptor may be OK in an enterprise system when it is going to be replaced in the 3 year hardware recycle. Whereas for your requirements Deskstar is probable better. However, I would welcome other comments. I take it that 300 GB was a typo. Can I take it also, that this for a small business that doesn’t want the hassles and cost of frequent hardware replacements.

Thank you for the answers. I am surprised. What is wrong with having internal boot drive of 300 GB. I checked Amazon and found that they don't even make 300 GB VelociRaptors anymore. They start with 600 GB. Am I so out of sync with modern times? As a matter of fact I've had half of my disk empty and the disk is full of software I either downloaded or created myself. I keep my SQL server on three external hard drives. Everything has worked fine until a month ago. I will look into your recommendations but large gigabytes scare me. --AboutFace 22 (talk) 21:39, 31 March 2016 (UTC)Reply

application that maintains perspective on subject when film is moving

I have seen this of late, and have no idea what it is called-old video that is shaky or taken from television news is somehow straightened to focus on the subject, therefore the captions at the bottom and even the shape of the screen often come out warped. It's a neat application, but I have no idea what one even calls such a thing. Help?--Kintetsubuffalo (talk) 10:49, 31 March 2016 (UTC)Reply

You may be thinking of "motion tracking" software. We have articles at Match moving and Image stabilization that may be helpful. --Thomprod (talk) 12:33, 31 March 2016 (UTC)Reply
Distorting the image seems like an odd way to do it. I realize that leaving it undistorted would allow the image to go partially out of frame, but that seems preferable, to me. If the shaking isn't too bad, you could crop the frame a bit so as to not see black bars intruding on the frame. Or maybe you could just extend the last column of pixels out to look a bit better than black bars. StuRat (talk) 15:12, 31 March 2016 (UTC)Reply
I'm nearly positive that OP is talking about some form of image stabilization. The images don't get distorted, the frame does. So instead of a guy jumping around the frame, the frame jumps around a (nearly) stationary guy [2]. This has become hugely popular in the past 5 years or so (or longer?) Here's an entire subreddit devoted to stabilized .gifs, here [3] is another. Here [4] is a tutorial on how to do it. SemanticMantis (talk) 15:48, 31 March 2016 (UTC)Reply
Right, but then you have to decide what to do about the part of the image that goes off the frame. There are several options:
1) Distort the image so it doesn't go off the frame.
1a) Compression at the edge(s) that goes off frame.
1b) Stretching at the edge(s) that falls short (or just extending the last pixel, as I suggested).
2) Shrink the image down so that no parts goes off the frame. This would still have black bars, on one or more sides, changing in size.
3) Crop the frame so the parts of the image falling short of the original frame no longer do.
4) Some combo of the above. StuRat (talk) 15:56, 31 March 2016 (UTC)Reply
HERE and HERE are some good examples. In the original StarTrek footage, the camera was bounced around as the cast of the show jiggled around in their seats...the result is fairly convincing. When you stabilize the image to remove the camera bounce - it reveals just how lame the actors look when they are doing this! Aside from curiosity value, there is value in stabilizing an image - for example in hand-held camera footage where some camera jiggle is inevitable, and undesirable.

Windows 10

My desktop runs Win7 Home Premium, SP1. It has an Intel Celeron CPU G540 @ 2.50 GHz, 6.00 GB installed RAM, 5.90 GB usable. I receive the offers to install Win10, which say my system is suitable. Is it worth installing, or would it be stretching my system's resources a bit far? Thanks, @@@@

Others have had more experience with this than I have, but this says that it meets the minimum requirements. However, that is not enough to give a good experience. My daughter is running it on a computer that had only 4GB of RAM, and it was quite sluggish. I bumped it up to 6GB and she saw a noticeable difference. A little later I raised it to 8GB, but she didn't comment about the difference. So I think 6GB will be OK. (But memory is about $5 per GB, so you can add two 2GB sticks for about $20.) My guess is that the processor will give you performance about like what you are used to. Bubba73 You talkin' to me? 20:21, 31 March 2016 (UTC)Reply

Would a 4K Galaxy Note 6 have shorter battery life?

Sure it's a phablet and rumored to have a slightly bigger 6 inch screen so the battery will be big but the tech is so new that the only 4K phone (only 8 months older than the Galaxy Note 6) just interpolates what the 4K pixels should be from a 1080p image. Otherwise the CPU and GPU load would cause poor battery life. As much as I believe we need ubiquitous 4K OLED phablets to enter the future if it doesn't browse for 10 hours like the Note 4 or 5 or is fake 4K for endurance then anything my eyes might see would make so little difference I'd just get a 1440p Note instead.

4k on a phone/tablet ? Can you possibly tell the difference on a screen that small ? Seems like worrying about how many angels can be carved on the head of a pin, to me. StuRat (talk) 03:08, 1 April 2016 (UTC)Reply
  • "Can you possibly tell the difference on a screen that small"
Yes, the tiny colon in the corner of my s key looks cloth-like because of the black lines between the pixels and it's rendered at 441 pixels per inch. Anything that's a uniform lighter color has pixel texture, at least if I squint from 4 inches. I also see color haloing from the right side of the pixels being redder than the left (mild). A 1440p screen that is 5.7 inches would only shrink the pixels to 76% as big. I think I could still see them then, but maybe only on primary color backgrounds since the subpixels look like this (I can see the 1080p texture up to about the distance I normally use the phone (half foot) if I squint). The inevitable 6 inch screens (from smaller bezels) would make them 80% as big. Also, there are some slight benefits to a more than a minimal retina screen. It'd be cool to browse Google Maps satellite with a magnifying glass. Scratches so small that you wouldn't even care if the white pixels were really white won't show the subpixels as much or at all (I don't use a protector because it makes the thickness feel less futuristic and even with care it'll likely get microscratched eventually). If it's so humid it fogs where you touch the parts under the fog will look better. And water on the screen won't make the subpixels as obvious (hey you can use a non-waterproof phone with wet hands or in the shower if you're really, really careful) That said 4K is such a minor, minor plus that there's a lot of things I'd rather have instead. Like 0.3 inches less bezel or mobile Java or a handlaser that can cut wood to play with (whether it's part of a phone or not). Sagittarian Milky Way (talk) 01:37, 2 April 2016 (UTC)Reply

Apparent Calming

Does playing on the computer calm the brain?.. a bit like watching TV? Has any research been done on this apparent effect?--178.101.224.162 (talk) 00:02, 1 April 2016 (UTC)Reply

Yes there have been quite a few studies, here is a systematic review of studies related to the use of video games in a clinical setting. The conclusions are not yet very strong but promising. Vespine (talk) 01:58, 1 April 2016 (UTC)Reply
Here is a specific study addressing reducing pre-operative anxiety in children, which in my opinion very well fits the definition of "calming". Vespine (talk) 01:59, 1 April 2016 (UTC)Reply
I should expect it would very much depend on the game you were playing. Some are designed to be relaxing, where there is no time limit or competitor. Solitaire comes to mind.

What happens if data centers are destroyed by nature or bombers?

How will the Internet survive? What will businesses do if they store massive amounts of data at data centers? 140.254.70.25 (talk) 19:24, 1 April 2016 (UTC)Reply

The internet was designed to survive some cities being destroyed by thermonuclear explosions. As for businesses, the stupid ones (the ones who only store data in one data center) will lose all their data, while the smart ones (the ones who make regular backups stored in widely scattered locations) won't. --Guy Macon (talk) 20:18, 1 April 2016 (UTC)Reply
The idea that the Internet was designed as a communications network to withstand a nuclear war is a myth. The Internet started as simply an experiment in networking computers so people could use them remotely, which was a big deal at the time as the smallest computers were the size of a couple filing cabinets and cost as much as a house. (The grain of truth behind the myth is that RAND and the DOD considered that packet switching would be more resilient in the face of large-scale network disruption, but "withstand a nuclear war" was never a formal ARPANET objective.) As to the original question, well, then those data centers will be destroyed. If you're following good practices you have backups in separate locations, but it will still cause disruption. The Internet is just a bunch of computers that talk to each other. There's nothing magical about it. The Internet wouldn't do any better than any other infrastructure, like the electrical grid or water system. --71.110.8.102 (talk) 21:25, 1 April 2016 (UTC)Reply

It's a bit of an overstatement to say that "stupid" businesses keep their data in one location. Many small businesses either have backups in a nearby but not identical location. And many use backup services. If whatever disaster there is destroys the data centers and the business's computer, that's not necessarily stupidity but more bad luck.

Whether this is stupid or not, it depends on how valuable the data are, and how high is the risk of multiple destruction of data center and business computer in one go.

Used printer, only Windows XP drivers available

Could I install the drivers of a used printer, which only has Windows XP drivers available? The model was discontinued, so there is no "take a look at the manufacturer's web-page for updated drivers." The most recent drivers are for XP, but I have only Windows 8.1 and a secondary computer with Ubuntu. Would Windows 8 accept the old drivers? Could I run the drivers using WINE in Ubuntu?--Scicurious (talk) 23:05, 1 April 2016 (UTC)Reply

You could try the XP driver. If that doesn't work, you might be able to find a generic driver for 8.1 that works. I'd look for drivers for similar models. Also, if it can't be used as a printer, and it's an all-in-one unit, you can probably still use it as a copier. StuRat (talk) 23:14, 1 April 2016 (UTC)Reply
I don't have the printer at hand, someone would send it to me. The printer I would get for free, but I'd have to pay for the shipping. So, what are the chances that I will work as a printer? --Scicurious (talk) 23:20, 1 April 2016 (UTC)Reply
My guess is that I would estimate about a 80% chance that it would print just fine if you told Windows 8 that it was a Laserjet 4 (if it's a laser printer) a Deskjet (if it's an inkjet) or an Epson (if it's a dot matrix). I would estimate a 10% chance that Windows 8 will find a working driver when you hook it up, and I would estimate a 20% chance that Windows 10 will find a working driver. Try googling "windows 8 rasterblaster 9000 (or whatever the model is) driver" and see if anyone else has got it working. Also, don't pay for shipping if you cannot find an online source for ink/ribbons/cartridges. I had to recycle a perfectly good Commodore dot matrix that was working fine under XP because the ribbons became unavailable (nothing beats wide greenbar fanfold for studying and marking up program listings). --Guy Macon (talk) 23:52, 1 April 2016 (UTC)Reply
The cost for shipping a printer has to be almost as much as a new inkjet printer costs, so I wouldn't bother with an iffy one. If it's a really expensive printer, like a color laserjet, then maybe it's worth the risk. StuRat (talk) 06:02, 2 April 2016 (UTC)Reply
That's indeed the case.Scicurious (talk) 11:55, 2 April 2016 (UTC)Reply
Printing in Linux is done via the CUPS (Common Unix Printing System); it can be installed via Ubuntu's package manager; it normally uses foomatic to handle convert the document to the printer-specific commands. It will be autoinstalled alongside CUPS. It should be possible to share the printer from Ubuntu to Windows; you might need SAMBA on Unbutu for this. LongHairedFop (talk) 14:23, 2 April 2016 (UTC)Reply
Another thought, install a Windows XP emulator on your PC and use that to print. I'd only try this method if nothing else works. StuRat (talk) 15:13, 2 April 2016 (UTC)Reply
Yes, agree with StuRat. If you have the time – strongly suggest installing a VM on Ubuntu. VirtualBox will do and its free. For this, it is far better than Wine. Then just instal Windows into it. The Windows XP drivers should then drive the printer. The bonus is, that once you have a VM, you can run many other operating systems with out affecting the primary OS that your computer runs on. Another advantage of a VM is when you get one of those scam telephone calls, asking if you have a problem with your computer running slow etc. One can play along with their game and waist their time too. The scam usually involves them convincing you to down load some remote access software like TeamViewer for example. They then – before your very eyes – do things on screen that may look impressive to some – and then demand payment. Should one then suspect a scam and question, they get the hump and start deleting your files – to which you have just given them access to. However, if you direct them to a VM and they endeavour to mess that up. One only has to click on 'roll back' and the OS is back to normal. Ho, Ho. Also, a VM is very much worth installing because it make you computer less dependant on a singular OS and frees it up.--Aspro (talk) 17:14, 3 April 2016 (UTC)Reply

Microsoft Word vs XL: sibling rivalry?

Time for my annual visit to the Computing Desk.

  1. In XL, a spreadsheet opens at the place it was last used. In Word, a document always opens at the start.
  2. In XL, merely copying a cell or group of cells into the clipboard for use elsewhere, without changing the source sheet, prompts the system to ask whether you want to save. No such thing applies in Word.

Since these softwares are siblings, why were these features organised so differently? -- Jack of Oz [pleasantries] 00:12, 2 April 2016 (UTC)Reply

I take it you mean Microsoft Excel? I've not ever observed your second feature in more than 25 years of use of the product. --Tagishsimon (talk) 00:21, 2 April 2016 (UTC)Reply
Yes, Microsoft Excel. Well, that's odd. I've been using Excel in various versions in various workplaces and at home, on different computers, also for about 25 years, and it's something I've always noticed and wondered about. -- Jack of Oz [pleasantries] 01:31, 2 April 2016 (UTC)Reply
So what exactly do you do to precipitate this? iirc, my mo is to mark a group of cells with mouse or shift & cursor keys, then ctrl-c or ctrl-x to copy to the clipboard, and ctrl-v to paste. Nada save. --Tagishsimon (talk) 01:40, 2 April 2016 (UTC)Reply
Yes, that's exactly it. I just opened an existing document, marked a cell with the mouse, used Ctrl-C to copy, then pressed Close - and I was asked, as I always am, whether I wanted to save or not. I made precisely zero changes to the document, so there's nothing to save. I then tried an experiment, by opening a document and closing it again without copying anything, and it closed without further ado. So, it's definitely the act of copying something that sparks something in the software's brain. -- Jack of Oz [pleasantries] 04:14, 2 April 2016 (UTC)Reply
Doesn't happen on my ancient version of Excel 2003.--Phil Holmes (talk) 10:54, 2 April 2016 (UTC)Reply
It doesn't happen in my version of Excel either, but one possibility is that there is some macro running that has actually made a change to the spreadsheet. This can happen in Word too. There is a possibility that this macro might be malware. If you don't use macros, it might be wise to disable them. Dbfirs 11:21, 2 April 2016 (UTC)Reply
I'd never noticed #1, but #2 drives me crazy.
I wouldn't assume there's any rhyme or reason to it. For one thing, Word and Excel aren't siblings; they're pretty much different species. (Heck, even Excel-on-Windows and Excel-on-Mac aren't siblings; they're merely cousins.)
I can tell you based on software I maintain that perfectly maintaining the "dirty bit" (i.e., the one that's set whenever you make a significant change to the document/spreadsheet, and cleared when you save it) can be really hard. There's lots of ways for the code to get just slightly confused, to accidentally set the bit when the user starts doing something that merely could change the document, and then not account for the fact that the user might hit 'Cancel' or otherwise not make a significant change after all.
My conclusion is that it hasn't been a priority for Microsoft to stamp out all bugs of the form program-claims-document-is-dirty-when-it-isn't-really, and consequently, there's a certain level of them. —Steve Summit (talk) 12:11, 2 April 2016 (UTC)Reply

Anyone have any clues about query #1? -- Jack of Oz [pleasantries] 00:01, 3 April 2016 (UTC)Reply
Nope, but I have a good apropos article - [6]. Going back to the save issue, I had understood you to mean it prompted a save when you hit ctrl-c, rather than determining a need for a save when exiting the spreadsheet. I can't recall what my excel experience was in that respect, and am too lazy to crank up a windows box to see :( --Tagishsimon (talk) 00:21, 3 April 2016 (UTC)Reply
But not too lazy to come here and expend keystrokes to tell me you're too lazy.  :)
Thanks for the link. -- Jack of Oz [pleasantries] 06:46, 3 April 2016 (UTC)Reply

If any of your cells contain dynamic data (possibly macros, possibly links to external spreadsheets/data sources, definitely the use of temporal functions such as the TODAY() function), then you will be prompted to save every time you close the file, even if you haven't edited it. I'm not sure what could cause it specifically to occur only when you copy a cell (and not occur when you don't copy a cell), but the act of copying must trigger some function/macro that Excel interprets as being a change from the base file that was opened. Good luck, and let us know if you figure it out! Zunaid 11:47, 3 April 2016 (UTC)Reply

Security Reviver

I attempted to load the malwarebytes anti-virus and got "Security Reviver" instead. It says it has found two highly serious malwares. . . and his is on a new machine! What is happening? Is this legitimate? --Halcatalyst (talk) 17:13, 2 April 2016 (UTC)Reply

If you thought you were installing one product and got another instead, it's surely a scam. There are lots of fake malware scanners that find fake malware on your machine to entice you to buy the professional version that will claim to remove it while actually doing nothing.
To avoid making this mistake in the future, find the wikipedia article for the software (Malwarebytes in this case), and click the link in the sidebar to get to the official web site. Also, install an ad blocker (uBlock Origin may be the best) so that you won't see ads that look like download buttons. -- BenRG (talk) 18:15, 2 April 2016 (UTC)Reply

HTML on Win7 / MSIE11

I'm running both MSIE 11 and Firefox on my Win7pro PC. I use a local page as my startup page to form a kindof sorted favourites page. I list obfuscated bits of it here:

 <!DOCTYPE html>
 <!-- saved from url=(0014)about:internet -->
 <html>
 <head>
 <title> Index. </title>
 <script>
   function gotopage()
   {
     var url = document.getElementById('page').value;
     if( url != "" )
     {
       url = "http://xxxxxx.invalid/" + url;
       window.open(url, '_top');
     }
   }
   document.onkeypress = function(evt)
   {
     if (evt.keyCode == 13)
        gotopage();
   }
 </script>
 </head>
 <body bgcolor="#c0c0ff">
 <h1 align=center> <a name="start"> Index.</a> </h1>
 <h2> Local </h2>
 <p>
 [ <a href="file:///D:\Data\xxxxxx.html"> xxxxxx</a>
 ] </p>
 <h2> Online </h2>
 <p>
 [ <a href="http://www.google.co.uk"> Google</a>
 ] </p>
 <p> <input type=button name=goto value="Go to page" onclick="gotopage();"> 
 <input type=text id=page size=15> </p>
 </body>
 </html>

It all works fine in firefox.

In MSIE, the local links to files on my hard drive no longer work since I added the goto textbox.

If I enclose the input para in <form> </form> then the local links work, but the Return press doesn't get detected.

If I remove the input para, the local links work.

Any idea how to make it all work simultaneously in both MSIE and in Firefox?

Thanks -- SGBailey (talk) 22:28, 2 April 2016 (UTC)Reply

I haven't tested it, but try putting <form> </form> around the input elements and changing type="button" to type="submit". -- BenRG (talk) 04:04, 3 April 2016 (UTC)Reply
In MSIE (untried in Firefox), that stops the Goto button working, it stops RETURN/ENTER working and the local URLs still don't work. Omitting the <form></form> but changing to "submit" works the same way as "button". If I can't fix it, I'll put the button and text box on a page all by themselves with a local link from my index page - but that is admitting defeat.
There must be a way to have: Internet links, local links, internet links derived by javascript from text input on a button and on Return/Enter. It seems such an obvious thing to want to do. (Note I need line 2, otherwise MSIE hiccups when page is loaded.) -- SGBailey (talk) 05:44, 3 April 2016 (UTC)Reply
After changing the number in the second line from (0022) to (0021), it works for me in IE and Firefox. (It's supposed to be the number of characters in the immediately following URL.) I also changed xxxxxx.xxx to xxxxxx.invalid. -- BenRG (talk) 09:38, 3 April 2016 (UTC)Reply
I made some additional changes/improvements, but it worked for me in both browsers before these changes. The about:internet line is taken from here. -- BenRG (talk) 09:46, 3 April 2016 (UTC)Reply
Oh well, thanks anyway - the msteries of MSIE! -- SGBailey (talk) 10:29, 3 April 2016 (UTC)Reply

White text on a black background

Hi! I am looking for a skin (or stylesheet) that shows Wikipedia with white text on a black background. Preferably Vector-based. The Quixotic Potato (talk) 03:37, 3 April 2016 (UTC)Reply

You might be able to adapt this Stylish theme. -- BenRG (talk) 09:54, 3 April 2016 (UTC)Reply
Another option is to use the accessibility options on your PC to invert all colors. Of course, this affects everything, not just Wikipedia. StuRat (talk) 17:30, 3 April 2016 (UTC)Reply

This problem has happened to me before, though it is not happening now. I have no mouse, just a touchpad and two keys (left and right) on my laptop. I came across a solution, which I have since forgotten. It involved a particular key combination (like pressing Ctrl+Shift) or pressing both left and right keys simultaneously. I found the solution with Google. Does anyone know what this solution is or was? — Melab±1 19:01, 3 April 2016 (UTC)Reply
