microscopic font on youtube

I just logged into my youtube account and suddenly I find everything in a microscopic typeface in which it did not formerly appear. It's about one-third the size of any reasonable font and I fear physical injury from reading it. How can I change it back to a normal font size? And why did it change? Michael Hardy (talk) 05:14, 21 June 2013 (UTC)[reply]

Perhaps the browser got zoomed out? Try using control and the + plus key to zoom the text back in. Control and the mouse wheel could work, too. --Mark viking (talk) 06:01, 21 June 2013 (UTC)[reply]
If it were the browser, then youtube would not be the only site on which this happens. Michael Hardy (talk) 21:21, 22 June 2013 (UTC)[reply]
YouTube's been undergoing radical (IMHO as a relatively long-time user) changes recently, so it could just be some type of glitch you're experiencing. If what Mark suggested isn't the case, try logging out and logging back in. --Yellow1996 (talk) 18:35, 21 June 2013 (UTC)[reply]
Firefox does text size changes on a per website basis. Hinted at here and workround requested here. I guess you are not using Firefox or you would be used to this happening. Thincat (talk) 22:28, 22 June 2013 (UTC)[reply]

What hub has THE MOST USB ports you have EVER seen (that I can buy?)

I don't think a 28-port is enough of a USB hub in the long-term. --70.179.161.230 (talk) 06:27, 22 June 2013 (UTC)[reply]

The biggest I've found is 49 ports at [1]. If you read our article USB hub it goes into what the maximum number of devices you can get nesting hubs and such, which is 127-#of hubs; it looks like you can only layer them up to seven layers too. What are you using this for that 28 isn't enough and that there is no alternative for?Phoenixia1177 (talk) 10:35, 22 June 2013 (UTC)[reply]
Wow and I thought the 6 I used to have on my old desktop was overkill! --Yellow1996 (talk) 20:20, 22 June 2013 (UTC)[reply]
(edit conflict) This thread I uncovered seems to support what Phoenixia said; and one of the commenters also mentioned an 80-port hub... but I discovered that it's only for charging stuff. Still interesting, though. --Yellow1996 (talk) 20:28, 22 June 2013 (UTC)[reply]
Would I be able to BUY that forty-niner hub? Do you know where I'd get a good deal on it? --129.130.36.175 (talk) 20:25, 22 June 2013 (UTC)[reply]
Right here. Yours for only $1,539.90! --Yellow1996 (talk) 20:32, 22 June 2013 (UTC)[reply]
Wow-ee! Thanks anyway, but how about for under $100? --70.179.161.230 (talk) 05:47, 23 June 2013 (UTC)[reply]
I seriously doubt that you'll find any with that many hookups for under a $100. Moreover, there seems to be some indication that the bigger hubs don't have large power outputs, so depending on use, may not be that useful. What is it you are trying to do? Perhaps there is another way. If not, you might be better served by nesting smaller hubs. How many ports do you actually need for your purposes? You might also consider buying an old computer and using it for a second collection of nested hubs; given that the bigger hubs are one unit, if it fails, you lose the whole thing; multiple cheap pieces may be easier to maintain (this depends on your needs though).Phoenixia1177 (talk) 06:51, 23 June 2013 (UTC)[reply]

Sorry for not wording it correctly. What I meant to say was: "What USB hub will offer the most ports for under $100?"

Also, I have two laptops (one of which will stay at home at all times.) I suppose once I get to connect the 126th / 127th device, I'll probably afford a new laptop anyway, so the one that currently travels will be another stay-at-home. --70.179.161.230 (talk) 11:10, 23 June 2013 (UTC)[reply]

You are under no obligation to answer, I think we are all just curious: Why do you need so many USB ports? Mingmingla (talk) 16:29, 23 June 2013 (UTC)[reply]
The large-quantitied hubs are generally geared towards companies, making the prices quite high (because they'd have a lot more money to spend than the average home user.) So, you probably won't find one that large for under $100. --Yellow1996 (talk) 17:28, 23 June 2013 (UTC)[reply]
The MondoHub (28 ports) from your initial post seems to be the winner of the "most ports for less than $100" award. I found this blog post which seems to confirm it. And I also am curious just what you need so many USB ports for. Dismas|(talk) 01:10, 24 June 2013 (UTC)[reply]
If I buy a primary item (in this case, a computer itself), I soon end up buying secondary accessories / components, bells-and-whistles, and other odds-and-ends to expand the functionality of the computer.
I may even buy a power-extender that is intended to keep a laptop's battery charged longer in case of a power outage just through feeding power through the USB back into the laptop, while all other times, the power-extender gets charged.
But if there are more humorously frivolous uses through USB connections, I'd like to find them out too. (I do hope to find a wireless power hub in order to mitigate clutter at the same time, however.) --70.179.161.230 (talk) 16:37, 24 June 2013 (UTC)[reply]
Sounds cool! Thanks for explaining your motivations to us! :) --Yellow1996 (talk) 17:05, 24 June 2013 (UTC)[reply]
Oh, and I thought the OP was replicating my Cheap-o RAID of 21 USB devices.
I set up a RAID of 20 flash drives for quad redundancy (up to 3 drives may fail) once. The hubs are USB-3. They support 16 devices (including one USB fan, because the array heats up quite a bit) each.
And that's the reason I bought two large hubs. It generates less waste heat than 5 small hubs (the tiny DC supplies are quite inefficient - that would be even more waste heat), and you don't need another HUB to connect those. - ¡Ouch! (hurt me / more pain) 05:57, 25 June 2013 (UTC)[reply]
Sounds like fun! How efficient did your setup prove to be? --Yellow1996 (talk) 16:02, 25 June 2013 (UTC)[reply]
It's close to saturating the USB-3 interface (and the PSU, unfortunately); however, it's not even close to a "real" RAID. It's meant for fault tolerance rather than performance. It uses a rectangular setup, 4x5, which can be rebuilt "by row" or "by column." The RAID will rebuild by column as well as by row if there's one device missing. The price is that of the 20 drives, only the equivalent of 12 drives can be used for data - the rest is used for XOR checksums.
The advantages - it's as cheap as triple-fault resistant systems get, and it's quite responsive even when rebuilding (and a 12:20 ratio isn't TOO bad either at that price).
Visit my talk page if you want more info about it, - ¡Ouch! (hurt me / more pain) 09:10, 27 June 2013 (UTC)[reply]
Ah, thanks for explaining more in depth for me. RAID is not one of my strong areas of knowledge, but luckily I was able to process all that you said ;) thanks again! --Yellow1996 (talk) 16:09, 27 June 2013 (UTC)[reply]
Do you have a link to information on that power extender? The power circuitry in a laptop isn't designed to allow the entire system to be powered through a USB port. The internals of the laptop need several voltages to operate, and they are regulated down from the battery voltage. They aren't designed to take a 5V supply from one of the outputs and convert it to the other voltages required by the system. I suppose the power extender could have keep other USB devices powered without draining the laptop battery, but I wouldn't trust it unless the other devices were routed through it, rather than assuming that they'll be on a common power bus inside your computer. 209.131.76.183 (talk) 12:57, 25 June 2013 (UTC)[reply]

Caterpillarpillar India country head profile

Hello,

I was looking for Caterpillar's country head's profile but I did not get any details about him.. — Preceding unsigned comment added by 98.214.113.170 (talk) 17:13, 22 June 2013 (UTC)[reply]

This is not really the right desk for this question, but I'll answer anyway. The country head for India and other parts of southeast Asia is Kevin Thieneman, also the president of Caterpillar Forestry Projects. It's hard to find much information about him, but here is a link to an interview he did last year. Looie496 (talk) 17:48, 22 June 2013 (UTC)[reply]

What is THE strongest, most protective phone case for the Samsung Galaxy Victory?

Best Buy didn't have one by Otterbox. I looked at Otterbox's website, and couldn't find any case intended for the Galaxy Victory either.

Sadly, Otterbox was the only case I have ever trusted to protect my phone in any fall / shock-inducing event. I have one on my old phone - the Xperia Play.

Is there a case for the Galaxy Victory that is at least as tough as, if not tougher than the Otterbox? Thanks. --70.179.161.230 (talk) 05:18, 23 June 2013 (UTC)[reply]

This page deals with your exact problem, and includes an e-mail from Otterbox on the matter. I found this case which has got pretty good reviews compared to others. You should probably wait for a user who has personal experience, though. Good Luck! --Yellow1996 (talk) 17:41, 23 June 2013 (UTC)[reply]

Sandisk USB drive needs to be formatted?

I bought a SanDisk Cruzer USB drive and used it on my MacBook for a few days with no problems.

When I inserted it into my friend's Toshiba laptop running Windows 7 Home, I received a message that I need to format the drive before I can use it.

I removed it and reinserted it into my MacBook. Finder gave me an error message that the disk I inserted was not readable by the computer.

Disk Utility seems to think it is a Firebird 64MB drive.

Some Googling revealed that this sometimes happens to brand new Cruzer drives which were sold unformatted. However, I had already been using the drive for a few days with no problems. Perhaps it could be a difference between Windows and Mac filesystems (such as Windows trying to read the drive as an NTFS drive)?

How do I fix my SanDisk Cruzer USB drive and get my data back? — Preceding unsigned comment added by 121.7.178.163 (talk) 13:10, 24 June 2013 (UTC)[reply]

I discovered some very helpful suggestions on this page. Looks like there is a lot of freeware that can do exactly what you want; though there are other things to try as well. As for getting your drive back up and running, you'll probably have to format it, but try some of those methods in the link first. (also, I think for most of them you'll need to put it into a windows computer...) Good luck! --Yellow1996 (talk) 16:01, 24 June 2013 (UTC)[reply]

Programming a bot to create city articles with census data for the Sorani Kurdish Wikipedia

Is anyone on here experienced in programming bots to create articles (like Rambot creating articles on the English Wikipedia on US cities back in 2003)?

A user from the Sorani Kurdish Wikipedia wants a bot to create articles on Iraqi cities in Sorani Kurdish. I found census data at http://cosit.gov.iq/pdf/2011/pop_no_2008.pdf (Archive) that has information on Iraqi cities. Would anyone know how to write a bot to automatically generate articles with this data?

Double USB on external Hard drive...?

A couple of days ago I discovered a 20GB (Toshiba) external hard drive in a junk pile (I'm not making this up!) And, sure enough, it works great. However, there's something odd I noticed about the USB cable - namely, it is a wire that branches off into two USB plugs! One of them has a thinner wire, and when plugged into my laptop does nothing except activate the green light on the front of the drive. The other plug's branch is a thicker wire, and when that one is plugged in I can hear the drive's inner mechanisms and my laptop recognizes it and I can remove/add files etc. One of the folders said it was modified in 1999 so I think it is an old drive; also the outer casing makes it very clear that it is using USB 2.0, which makes me think I might be right as to the age of it. So my question is: why the double USB wire? Has anyone seen something similar before? Thanks! --Yellow1996 (talk) 21:59, 24 June 2013 (UTC)[reply]

I've seen that before. The second one is supposed to give the drive extra power so that it doesn't overload the usb port, so its power demand is spread over two. 82.44.76.14 (talk) 22:22, 24 June 2013 (UTC)[reply]
Okay - makes sense; I had suspected it had something to do with power but wasn't sure because "one had ought to be enough!" ;) I'll have them both plugged in from now on (since I don't really ever have more than one device plugged into USB at once.) Thanks! --Yellow1996 (talk) 15:54, 25 June 2013 (UTC)[reply]

Is there a cable modem + wireless router that'll stay running in a power outage?

I appreciate that my laptop will still run, but in a power outage, I'm out an internet connection.

Is there any modem + wireless router that'll have some sort of battery backup? Any kind of mechanism that'll keep it running when the power's out? Hopefully. Thanks. --70.179.161.230 (talk) 02:46, 25 June 2013 (UTC)[reply]

Look at getting a UPS to keep your modem running. Of course, that only helps if the cable company's equipment also does not lose power. RudolfRed (talk) 04:51, 25 June 2013 (UTC)[reply]

Converting Currency to Text in Excel without losing formatting

Hi there,

I've got a bit of a conundrum. I've got an enormous excel sheet with lots of columns, many of which are formatted as currency. So essentially, the actual data that's in the fields is "7", "8.5", etc. However, the way they display in Excel is "£7.00", "£8.50", etc.

The trouble is, when I try and merge them into Word (2010 - same version of Excel), it loses all the formatting - and so my figures will display as "7" or "8.5" (or indeed "5.125") rather than "£7.00", "£8.50" or "£5.13"). I've attempted to use the "Confirm file format conversion on open" options on Word but they're not working for me.

Is there a way I can convert the Currency columns to Text columns without losing the currency formatting, and then import them directly as text into Word?

thanks

Seal Boxer (talk) 12:25, 25 June 2013 (UTC)[reply]

This is discussed in a Microsoft knowledgebase article here, and also here, which explains how you can use formatting codes in the merge fields to control how the amounts appear. Alternatively you could use the formula =TEXT(amount,"£#,##0.00") (in the spreadsheet) to convert the values to text in the right format first. AndrewWTaylor (talk) 13:34, 25 June 2013 (UTC)[reply]

Calculating text length tin SVG

I'm writing a program that puts out an xml file containing SVG. It contains variable text and I have to check if the text fits in a certain space (think of a box) or not. Googeling, I can see many people asking questions about that but haven't seen an answer (just workarounds). 77.3.170.153 (talk) 15:03, 25 June 2013 (UTC)[reply]

I don't think it is possible to do that using the SVG file alone, if that's what you're asking for. You can't calculate the width without knowing the detailed structure of the font, and that information is not included within an SVG file, at least not by default. What programming environment are you working in? Looie496 (talk) 15:12, 25 June 2013 (UTC)[reply]
Currently I'm using perl (module SVG), but I won't necessarily stick to that. And I need to calculate the text length when the SVG is still incomplete. With SVG there seems to be somthing like getComputedTextLength, but I need this beforehand, not in the final SVG file. 77.3.170.153 (talk) 15:59, 25 June 2013 (UTC)[reply]
As Looie496 says, text doesn't really have dimensions in abstract - those dimensions only exist in the context of a concrete font in a real render. To do this kind of thing you need an offscreen rendering context (whether that's a Cairo context, a browser widget, an invocation of imagemagick, or whatever) into which you do a temporary render of the text, and from which you can then extract the size of the resulting objects. Naturally if you're doing this a bunch, you want to try to keep that context around for a bit so you can reuse it, as much of the cost of this is generating the context in the first place. And I'm sure you're aware that the SVG you generate might not render with those dimensions on someone else's system (e.g. in someone else's browser), particularly if they don't have exactly that font. -- Finlay McWalterTalk 16:17, 25 June 2013 (UTC)[reply]
(ec) As I am the one generating the SVG I do have some control on which fonts should be used by a client rendering the picture. OK, I can have a half-baked file sent to another program to check the length, but this is not exactly what I have in mind. Ideally, the generating program (perl, or whatsoever) should have a function that returns the bonding-box for a given font and text. 77.3.170.153 (talk) 16:34, 25 June 2013 (UTC)[reply]
Of course one way around this is to use a fixed-width font, if that's possible. Or to use the maximum character width for the font. Looie496 (talk) 16:28, 25 June 2013 (UTC)[reply]
Unfortunately I need some astrological symbols and I'm pretty sure they are not part of any widespread fixed width font. 77.3.170.153 (talk) 16:34, 25 June 2013 (UTC)[reply]
Fixed width (monospace) only fixes the size of characters with respect to others in that same font (at that size). Rendering the same string on my machine with Cairo produces the following sizes for all the monospaced fonts:
      Andale Mono (129.0, 15.0)
      Webdings (108.0, 13.0)
      DejaVu Sans Mono (130.0, 15.0)
      TlwgMono (131.0, 13.0)
      PixelCarnageMonoTT (118.0, 11.0)
      Liberation Mono (130.0, 15.0)
      Courier 10 Pitch (130.0, 12.000000000000002)
      Nimbus Mono L (131.0, 13.0)
      Consolas (119.0, 14.000000000000002)
      Inconsolata (108.0, 13.0)
      Tlwg Typo (131.0, 13.0)
      Courier New (131.0, 13.0)
      FreeMono (131.0, 13.0)
      Ubuntu Mono (109.0, 15.0)
      Monospace (130.0, 15.0)
...which shows the folly of relying too closely on these kind of metrics when one wants to know how something will render on someone else's machine. For example, if the OP were to decide to use Consolas and lay things out accordingly, if someone viewed it on a machine without Consolas, which instead substituted Ubuntu Mono, the resulting text object would be 20% wider than they'd anticipated. -- Finlay McWalterTalk 17:45, 25 June 2013 (UTC)[reply]
For Cairo (which has a php binding), here's a simple program that does it (I wrote it in Python, but it's just a matter of syntax changes to make it php):
#!/usr/bin/python                                                                                                   
import cairo

surface = cairo.ImageSurface(cairo.FORMAT_RGB24, 1000, 300)
context = cairo.Context(surface)

context.select_font_face("Georgia")
context.set_font_size(20)

xbearing, ybearing, width, height, xadvance, yadvance = context.text_extents("hello there")
print width, height
-- Finlay McWalterTalk 16:38, 25 June 2013 (UTC)[reply]
Thanks to you and curse on Murphy, I have seen and used many languages, but python and php are one of the few I haven't used before. I guess and hope cairo is available for perl and/or java, too. I'll have a google and a try. Thanks again. 77.3.170.153 (talk) 16:45, 25 June 2013 (UTC)[reply]
Ah, what a nice day today, there actualy is such a module for perl: http://search.cpan.org/~xaoc/Cairo-1.103/lib/Cairo.pm So I thanky you again and calll ths question resolved (don't know how to produce this nice button here). I'm happy. 77.3.170.153 (talk) 16:54, 25 June 2013 (UTC)[reply]
If you wanted to do it in Java, you can use Java2D instead of Cairo:
import java.awt.*;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;

public class measure{
    public static void main(String [] args){
        BufferedImage im = new BufferedImage(1000, 300, BufferedImage.TYPE_INT_RGB);
        Graphics2D context = (Graphics2D)im.getGraphics();
        FontMetrics metrics = context.getFontMetrics(new Font("Georgia", Font.PLAIN, 20));

        Rectangle2D dims = metrics.getStringBounds("hello there", context);
        System.out.println("width:" + dims.getWidth() + " height:" + dims.getHeight());
    }
}
-- Finlay McWalterTalk 17:21, 25 June 2013 (UTC)[reply]
Regrettably, no. I need the SVG output. A rasterized image won't do. 77.3.170.153 (talk) 18:10, 25 June 2013 (UTC)[reply]
You can still do Java2D for the measurement (with all the caveats I've already harped-on about) and emit an SVG by another means. But the nice thing about Cairo is it can render to an SVG context (see the 2nd example here). -- Finlay McWalterTalk 20:08, 25 June 2013 (UTC)[reply]

Copying large files from PS3 HDD?

I've downloaded a couple large videos from the Playstation Store (the PS4 announcement video, 6GB, and the E3 Press Conference, 5GB). Like all game videos from the Playstation Store, they are just plain h264 movies without DRM. But Playstation 3 only seems to support FAT32 for USB attached external drives. And I get an error when trying to copy these files because I assume they are larger than the 4GB file size limit on FAT32 volumes. Are there other ways to get files off the PS3? Perhaps through the ethernet port? --Navstar (talk) 01:00, 26 June 2013 (UTC)[reply]

Ubuntu is like windows, in so much, that the first time you encounter it there is a steep learning curve before you get the hang of it. Linux is Not Windows However, preserver for no more than the 'same time' that it took you to learn windows and you will find Ubuntu (or Mint or any other the other popular Linux distribution) way easier to use and maintain than windows. Then, in a year or two's time you'll be posting here to ask “why don’t more people use Linux? It's a breeze.” It may only be that you have come across windows first, and so a better operating system now seems strange. Had it been the other way about, you would not even give windows (with all the hoops it requires you to jump though) a first let, alone second look. --Aspro (talk) 14:36, 26 June 2013 (UTC)[reply]

On demand web graphics

Can people suggest software that is good at creating on-demand graphics for web servers. In my particular application, we have large data files and we are looking for ways to extract and plot small subsets of that data in response to user requests submitted via a web interface. What existing software packages are good at such applications? The web interface itself will probably be PHP, but we can of course call other programs to generate the images as needed.

For general drawing, people use ImageMagick (libmagick), cairo, and GD. To do mathematical and statistical diagrams and plots there's things like matplotlib, GNU Octave, and gnuplot. There are also lots of charting libraries (which produce histograms, pie charts, and the like) such as pChart. -- Finlay McWalterTalk 10:38, 26 June 2013 (UTC)[reply]
There's another option you may consider: doing the plotting client side (in the web browser). There are several JavaScript charting libraries (which render to a Canvas element, or in some cases do things like pie charts and histograms with CSS). That way, rather than generate a PNG or SVG server side and send that, you can send the data (e.g. as JSON or XML) and render it in the browser. That can lower the amount of data you have to move on the network, but the big gain is you can make the render responsive and interactive - so the user can select what data to view, zoom around, turn labels on and off, etc. The downside of that is that it depends on the user having a newer browser. -- Finlay McWalterTalk 12:44, 26 June 2013 (UTC)[reply]
  • I think this depends to a great degree on the format of your data files and the types of information you want extracted. If they are spreadsheets or can easily be turned into spreadsheets, you might find that the easiest solution is to write macros for a spreadsheet program.

Recommender system in wikipedia

Hi ! I am currently working on recommender systems and someone mentioned to me that wikipedia had one and I can't find any mention of such thing though. Am I just blind and wikipedia does recommend articles to users depending on what they have already read ?

From what I understand, the "See also" section is filled out by users right ? Or is there any kind of system that recommends the articles which need to be in that "See also" section ? Thanks for your help ! Fperrotti (talk) 06:58, 26 June 2013 (UTC)[reply]

There's just the links in the articles. Wikipedia doesn't set a curriculum, so it's up to individual readers to set their own course through the articles. Sometimes the category links will lead you other places, and sometimes the portals on the page will have subject suggestions. Wikipedia content is sometimes linked from external things (like Wikibooks) which do set a curriculum, but the authors of a specific Wikipedia article can't know why someone came to read it, and so can't recommend where you'd go from there. The "see also" section certainly isn't a recommendation list, although it is sometimes misused as one - it should be links that are relevant to the article but that can't easily be worked into the article's text (where they'd have context) - an example of good practice is Extreme points of North America, which see-alsos other extreme-points articles. -- Finlay McWalterTalk 10:31, 26 June 2013 (UTC)[reply]
Wikipedia has an article about Recommender system about the subject, it doesn't operate one. Wikipedia also has articles on subjects like singular value decomposition which I'm surprised that article doesn't seem to link to but you do sometimes have to click around a bit on the links in an article to see what meat if any there is in Wikipedia about a topic.

SuggestBot suggests pages that may be of interest to an editor based on their edit history - so it's a bit like a recommender system. But I don't think anything in Wikipedia logs pages that you have looked at (as opposed to actually editing them) so it can't make recommendations based on what you have read.

An important point about Wikipedia is how it is structurally different from sites like Amazon and Facebook. Those deliver a personalised web experience; most visitors have an account and most of those are signed into it most of the time. That account means Amazon and Facebook know who their visitors are and deliver custom content based on their preferences, actions, and history. In contrast Wikipedia serves almost everyone the same content, with only a statistically negligible number (signed in editors) getting any kind of custom content. Amazon's and Facebook's value all lies in that individualised experience, but it comes at a massive cost to them. Wikimedia makes very effective use of cache (web cache and memcached), meaning it can serve the whole site with 1000 servers or so (I can't find an up-to-date number; it was 300 in 2008), but Amazon and Facebook both have a number of gigantic datacentres - Facebook spends half a billion US dollars a year on servers (ref). To properly support visitor-specific content over the whole visitor base at Wikipedia would mean abandoning that massively cache efficient architecture and adopting an Amazon-like architecture. So, handwaving the numbers a bit, implementing a recommender system at Wikipedia's massive scale might cost upwards of $200 million US.

Hi. When I created my Gmail account, I entered my real name in the registration form. The problem is that Gmail uses this real name as sender in the e-mails that I send to other people. How can I set Gmail to use an alternative name as sender instead? I can't find this option in Settings. Please don't tell me to create another account because I like my current account name. Thank you. --41.129.46.55 (talk) 15:23, 26 June 2013 (UTC)[reply]

Where can I find the Matlab Psychophysics toolbox?

I'm looking for the Psychtoolbox-3, but www.psychtoolbox.org is down. Does anyone know where it might be elsewhere located? Thanks in advance! --Rajah (talk) 16:02, 26 June 2013 (UTC)[reply]
