Advertising on Wikipedia
I'm suddenly seeing ads on Wikipedia. One right under the article title, and another right above an article's table of contents. I am NOT happy. I thought Wikipedia would never run ads? Was referred here from the Help Desk. On the last page with ads, the first was for weight loss tips, and the second was for an online game. Right now, there's an anti-drunk driving ad below the title. — Preceding unsigned comment added by 98.193.228.251 (talk) 01:35, 7 October 2012 (UTC)


 * Would you take a screenshot of the relevant portion of the page and upload it to an image-sharing site like Imgur? That would enable us to see exactly what's going on. Goodvac (talk) 01:38, 7 October 2012 (UTC)


 * Sure. Here you go: http://i1271.photobucket.com/albums/jj637/backagain2012/Ads.png. It's zoomed out to 80%. Also, accessing Wikipedia through an https:// connection removes the ads, and a full scan of my computer came up clean. 98.193.228.251 (talk) 01:46, 7 October 2012 (UTC)


 * Wow, that certainly is odd. What happens if you click "about this ad"? And can you right click on the image of one of the ads and paste the url of it here? I also see some text-link advertising on that screenshot (the underlined orange links). Where do those go? Goodvac (talk) 01:50, 7 October 2012 (UTC)


 * Fixed. Clicking "about this ad" brought me to a page for some browser toolbar, which was not malicious(even told me how to uninstall it), but didn't benefit me at all, and was installed without my knowledge or consent. Uninstalled the toolbar, and the ads are gone. 98.193.228.251 (talk) 02:00, 7 October 2012 (UTC)


 * Excellent. Glad it's gone. Goodvac (talk) 02:03, 7 October 2012 (UTC)


 * Yes, we recently had a similar case here. I'll mark this resolved. StuRat (talk) 04:42, 7 October 2012 (UTC)


 * How can you know that the toolbar was not malicious? Maybe you have now a worm installed in the background.


 * Every now and then someone appears here with the problem of wikipedia showing ads. OsmanRF34 (talk) 10:24, 7 October 2012 (UTC)


 * Well, Wikipedia sometimes does show "fundraising banners" at the top of pages that look like ads. –– Anonymouse321 (talk • contribs) 23:15, 8 October 2012 (UTC)
 * Which was not malicious(even told me how to uninstall it), but didn't benefit me at all, and was installed without my knowledge or consent. Anything that installs itself without permission, serves no good purpose, and puts ads where they don't belong is malicious adware in my book. I saw a similar toolbar placing ads on Wikipedia on a friend's computer and they asked me to get rid of it, he didn't know where it came from but I determined it came bundled with uTorrent.

http
i make an http get request for a jpg allowing gzip compression. the response is a code 200, and the "transfer-encoding" header says: "chunked". the same packet has gzip data (apparently random data), being the start of the image. how do i pick out witch future packets have the rest of the image? thank you, 70.114.254.43 (talk) 02:28, 7 October 2012 (UTC)


 * A level enquiry before we go any further: when you say "packets", do you mean TCP/IP packets, or do you mean HTTP chunks? Marnanel (talk) 02:34, 7 October 2012 (UTC)

tcp/ip, sorry. 70.114.254.43 (talk) 04:26, 7 October 2012 (UTC)


 * The combination of protocol(TCP), source address (the web server), source port (probably 80), destination address (your machine), and destination port will all be the same for each packet of the response. Docdave (talk) 04:15, 8 October 2012 (UTC)


 * Note than, on any system derived from, or influenced by, Berkeley Sockets, then the Operating System takes care of directing the data to the network socket handle. Your program just need use one of (C-like code given)


 * with appropriate error checking and retrying for partial reads or writes.
 * However, if you mean how to find then next packet in a network packet sniffer, then check its documentation, or ask here, with the name of the tool. CS Miller (talk) 05:34, 8 October 2012 (UTC)

software problems
i have a software for my chemist shop named cross of swil ltd. it can not take its daily back up. when i want to take back up it shows pkzip  can't open:d:/backup/c0212/bk071012.zip for write access! backup processing has completed now,testing the backup

pkunzip:  can't find:d:/backup/c0212/bk07101.zip testing completed.Rikisupriyo (talk) 11:21, 7 October 2012 (UTC)


 * You should make sure there is enough space on whatever device is your d:. Beyond that, because Cross is a proprietary application aimed at a very narrow market segment, it's pretty unlikely that anyone here will have any experience with it. You'd be much better advised to contact the dealer who installed it for you. -- Finlay McWalterჷTalk 14:01, 7 October 2012 (UTC)


 * Another possibility is that the software isn't authorized to open that file in that folder. If so, you would either need to change the folder to grant broader permissions, or have the backups run as "root" or "Administrator", depending on the O/S.


 * As far as root cause analysis, what happened between when the backups worked and when they stopped working ? StuRat (talk) 19:44, 7 October 2012 (UTC)


 * Sorry if it's presumptious, but have you even tried navigating to d:/backup/c0212/ and seeing what's there? Maybe your d: drive somehow unmapped it self of failed, or filled up (as suggested above), that would be the 1st thing to check. Vespine (talk) 02:43, 8 October 2012 (UTC)

how can i fix PKZIP: Rikisupriyo (talk) 11:27, 11 October 2012 (UTC)
 * By following Finlays and Vespines advice. PKZIP's errorcode 15 means: "The named .ZIP file is read-only or locked by another application and can not be modified. This may also occur on a Network drive if you do not have adequate access to that file to allow you to modify it." http://www.ousob.com/ng/pkzip20/ng208b4.php  Check how much diskspace is available (the most likely cause of your problem). Check if that folder on that drive is exists and is writable. Check if another program is using that same file (e.g. antivirus). You can even try creating that file manually (e.g. in Notepad). It can also be a permissionproblem. They (talk) 13:19, 13 October 2012 (UTC)
