Intel Xeon Processor 7500 Series

In regard of the Intel Xeon Processor 7000 Series, currently there are models which run from 7520 to 7560, and I'm wondering whether any higher model numbers have been announced by Intel for future availability. I tried Yahoo! Search, but wasn't able to get any relevant results. Thanks again. Rocketshiporion ♫ 01:56, 26 January 2011 (UTC)[reply]

Intel's next generation server chips will have a different naming scheme, with the "E7" designation basically replacing the 7000 series. See: [1]. Dragons flight (talk) 13:30, 27 January 2011 (UTC)[reply]

Qualcomm Brew Jailbreak

Are there any tools out there that can jailbreak Qualcomm's BREW or there new Brew MP platform and allow one to run unsigned Brew applications? And, possibly, does any custom Brew firmware exist? I'm interested in this because I might want to try programming on the upcoming HTC Freestyle. --Melab±1 ☎ 02:21, 26 January 2011 (UTC)[reply]

BREW is still not broken and probably will not be for a very long due to lack of interest and the complexity of its security. I know that while Verizon used BREW there was no activity in this regard and BREW had very few game choices. Meanwhile, the platform beneath BREW at the time, J2ME, had lots of activity including many big companies like EA making games. --Tatsh (talk) 21:16, 26 January 2011 (UTC)[reply]

Trackbacks for Wikipedia articles

I'm trying to trace mentions of Wikipedia articles in the wider web. Searching the URL of the article in Google throws up some links, but not most as they are embedded or shortened. Topsy performs this service for Twitter ([2]), but is there anyway of doing it for the Internet at large, or at least, say, the blogosphere? Appreciate any related tips, Skomorokh 03:10, 26 January 2011 (UTC)[reply]

Hyperlinks are unidirectional - so there's no way to generate a complete index of all pages that contain links to a specific article. You can search through massive indexes of web-pages that have been spidered and analyzed; but you'd be essentially writing your own search engine in the process. Or, you can use the indexes of major commercial web-search-engines. Google used to support a "link: keyword, for example you could query linkto:en.wikipedia.org/wiki/Albatross - but I just experimented, and I don't think the results are significantly different than searching without the special keyword.

A Google search for who links to me finds other websites, such as http://www.linkpopularity.com/.

Why do you want to do this? The idea creeps me out a bit, but if it's for academic purposes there are some snapshots of fairly large fragments of the web that you might be able to get access to. 67.122.209.190 (talk) 05:50, 27 January 2011 (UTC)[reply]

YouTube comments

If you make a comment in reply to someone and it never shows up, is it actually there? Because there's been one occasion where I replied to someone, I was never able to see what I wrote, yet they replied to my comment. However, the comment that I thought never showed up was visible on my cell phone. But in another instance where the same thing happened, the comment was never visible on either my computer or phone. How do I know if it's there or not? I don't want to make a double post days after writing the original comment. 24.189.87.160 (talk) 03:53, 26 January 2011 (UTC)[reply]

It sounds like it could be a caching problem, so that you are not seeing the most current version of the page: you could try Ctrl+F5 to force the page to reload (that works in most browsers under Windows and Linux, but you may need a different command on other systems). --Colapeninsula (talk) 15:19, 26 January 2011 (UTC)[reply]

Cross-compiling C++ programs for Mac OS X on Linux host

(I first asked this here)

Is it possible to cross-compile C++ porgrams on Linux host machine for Mac OS X target machine? 85.131.56.200 (talk) 06:15, 26 January 2011 (UTC)[reply]

Possible, but not easy. In principle the GNU Compiler Collection (which includes a C++ compiler) can cross-compile with almost any combination of systems, though you need to recompile GCC for each different combination of host and target system. So in practice, it's not simple. Googling produces a few answers, here's one discussion[3] which recommends IMCROSS[4] although they say it's not very simple. --Colapeninsula (talk) 15:26, 26 January 2011 (UTC)[reply]

One project that has succeeded in doing this at least once is OpenTTD. Should be compatible. [5] A problem you may often run into with cross-compiling is whether or not ALL the libs you use will work. 90% of the time everything Glibc and other libs do on Linux works on Windows (Mingw) and Mac OS X/Darwin; sometimes you might see missing headers, missing functions/macros, etc. As far as ports that you can plug into a compiler targeting OS X, I have never seen that. --Tatsh (talk) 21:01, 26 January 2011 (UTC)[reply]

Why don't you compile natively for Mac OS X? You can get GCC for it, which is what Apple seem to use themselves. Cross-compilers are normally only used if the target is an embedded device (too small to host to tool-chain), or too new (no full operating system or compiler for it yet). CS Miller (talk) 22:26, 26 January 2011 (UTC)[reply]

As far as I know, Apple now even ships Xcode and gcc pre-installed on any new Mac (starting with, IIR, MacOs 10.3 or 10.4). I certainly don't remember having to install it on any Intel-Mac, although it was an Apple Developer download for my first Powerbook G4. --Stephan Schulz (talk) 15:28, 27 January 2011 (UTC)[reply]

Harump. Apparently, my memory is crap. According to our article, Xcode is an optional install from the OS DVD with 10.4 and later. It probably migrated with me to the later version...--Stephan Schulz (talk) 15:31, 27 January 2011 (UTC)[reply]

Ubuntu and Wubi recovery

I used to run Windows Vista on my laptop with Ubuntu (10.04 LTS) installed via Wubi. Recently, it refused to boot up under Ubuntu, so I booted up under Vista, backed up the entire hard drive onto an external drive, and nuked the drive (the internal one) with Ubuntu 10.04 LTS. The machine is now a single-OS system running Ubuntu 10.04 LTS.

I would, of course, like to recover the content I had in the Ubuntu sector before the crash, but I cannot find a way to access the root.disk file containing that content. How can I do this? --Lucas Brown 16:27, 26 January 2011 (UTC)[reply]

What tool did you use to do the backup? Looie496 (talk) 17:35, 26 January 2011 (UTC)[reply]

While I've never used it, the examples at [6] suggest that the root.disk file is just a regular disk image. You should be able to mount it (as root) with mount root.disk /mnt -o loop (assuming /mnt is the desired temporary mountpoint), possibly adding an explicit -t option if the filesystem type can't be autodetected.—Emil J. 17:52, 26 January 2011 (UTC)[reply]

Taking out line breaks en mass in Word

At my office we are constantly taking pdfs and recognizing the text using OCR (optical character recognition) and then copying and pasting the recognized text into Word. The problem is that when you paste the copied text into Word, there are always numerous line breaks (carriage returns). If it’s a long document, one ends up spending a significant period of time taking these out, by going to the end of a line, hitting delete and then putting in a space.

So my question is, is there any way to take out all of the line breaks, en mass?--108.14.201.140 (talk) 21:56, 26 January 2011 (UTC)[reply]

I'm not a Word expert, but my guess is that there probably is. Why bother, though? Your first mistake was pasting it into Word. Paste it into Notepad instead. Then you can use all sorts of general-purpose text editors to massage it as you like. --Trovatore (talk) 22:10, 26 January 2011 (UTC)[reply]

You can find and replace special characters. Generally the way to do it is to search for all instances of two line breaks and change them to a string which does not appear in the text; then knock all the single line breaks on the head, and then turn the string back into double line breaks. That way you preserve paragraphs. In word 2003, expand the find box using the "more" button to see the Special button. Take it from there. --Tagishsimon (talk) 22:22, 26 January 2011 (UTC)[reply]

Yes. Press CTRL + H to open the Find and Replace dialog box. Then, in the top field, enter ^p and in the bottom field, enter nothing and press the "Replace All" button. That will remove all carriage returns. If you'd rather just remove duplicate returns, enter ^p^p instead.--Best Dog Ever (talk) 22:21, 26 January 2011 (UTC)[reply]

Strictly, if it's line-breaks and not carriage returns, you need ^l.--Phil Holmes (talk) 03:20, 27 January 2011 (UTC)[reply]

That's right if they're pressing SHIFT + ENTER instead of ENTER after every paragraph, but pure line breaks are so rare that I chose not to mention it.--Best Dog Ever (talk) 04:24, 27 January 2011 (UTC)[reply]

Doesn't word have an "import with CRLF at end-of-line" filter in the advanced open menu? CS Miller (talk) 22:27, 26 January 2011 (UTC)[reply]

I don't believe there is an advanced open menu in MS Word.--Best Dog Ever (talk) 23:48, 26 January 2011 (UTC)[reply]
