Search ranking for important keywords has gone down drastically [duplicate]

- by Vaivhav

This question already has an answer here: How to diagnose a search engine ranking drop? 5 answers Firstly, we are a small entrepreneurial team of 3 persons and I am more like an amateur webmaster of the company's website as we cannot really afford a technical guy/department right now. A few weeks earlier, our website traffic and rankings for most keywords decreased overnight. I did a lot of reading henceforth and learned about Penguin 2.1 which people said is the reason for the drop. Something like this had never happened before. Now, I have gone through the entire Google webmaster help section. It says there that if a manual penalty is taken against us, we would notice a message in Manual Actions page. So far, we haven't received any notice from Google for web spam. Some SEO guys I contacted said they found spam links in our backlink profile. I do believe I had mistakenly purchased a cheap link/SEO scheme when I was yet very new to SEO. This was more than a year back but since then we have been legitimate. Moreover, how do I find out which is a spam link and which is not? Our content is all original, refreshing and the best you will find in our niche. We also have a blog but on a different domain (wordpress.com) from where we send out anchored links to our business website. Is this a good thing to do? Now, how should we proceed and recover our traffic/rankings. I tried searching in webmasters for a way to reach google and ask them why the traffic has decreased suddenly, but I couldn't find a contact form or something. Can someone please go through our website and help in making things more clear regarding the reason for the drop, along with a solution. Will really appreciate this as I can't get to figure this out and its taking a lot of time. Vaivhav

Links opened by left-click in IE8 take forever compared to middle-mouse button

- by Bigbio2002

When I use the middle mouse button to open a link in a new tab, it works instantly. However, if I left-click the link to open it normally, IE8 freezes for about 5 seconds before the popup window opens. I'm sick of all the slowness and the glitchiness and the memory hogging, and I just want it to work as well as all the other browsers out there. Anybody else experiencing this and have any tips? Note: It's not the Java SSV helper or the Skype addon (because I have those disabled). I'm looking for some advanced solutions that I can try. (God, I hate IE8, but I'm a loyal Microsoft follower so I refuse to switch to Firefox. )

How to handle fine grained field-based ACL permissions in a RESTful service?

- by Jason McClellan

I've been trying to design a RESTful API and have had most of my questions answered, but there is one aspect of permissions that I'm struggling with. Different roles may have different permissions and different representations of a resource. For example, an Admin or the user himself may see more fields in his own User representation vs another less-privileged user. This is achieved simply by changing the representation on the backend, ie: deciding whether or not to include those fields. Additionally, some actions may be taken on a resource by some users and not by others. This is achieved by deciding whether or not to include those action items as links, eg: edit and delete links. A user who does not have edit permissions will not have an edit link. That covers nearly all of my permission use cases, but there is one that I've not quite figured out. There are some scenarios whereby for a given representation of an object, all fields are visible for two or more roles, but only a subset of those roles my edit certain fields. An example: { "person": { "id": 1, "name": "Bob", "age": 25, "occupation": "software developer", "phone": "555-555-5555", "description": "Could use some sunlight.." } } Given 3 users: an Admin, a regular User, and Bob himself (also a regular User), I need to be able to convey to the front end that: Admins may edit all fields, Bob himself may edit all fields, but a regular User, while they can view all fields, can only edit the description field. I certainly don't want the client to have to make the determination (or even, for that matter, to have any notion of the roles involved) but I do need a way for the backend to convey to the client which fields are editable. I can't simply use a combination of representation (the fields returned for viewing) and links (whether or not an edit link is availble) in this scenario since it's more finely grained. Has anyone solved this elegantly without adding the logic directly to the client?

A Linux DHCP server that will listen on an non-broadcast (tap) interface?

- by TomOnTime

Are there any Linux DHCP servers that will listen to what Cisco calls an "unnumbered" interface, or what others might call a "NBMA" (non-broadcast) interface. I have a Linux system that connects to a number of others using GRE tunnels. The machines on the other end send DHCP requests to this machine, I can see them with tcpdump. However, ISC DHCP 3.0.3 refuses to listen to the interface because it is non-broadcast. The interface I'd like DHCP to listen to is: tap2 Link encap:Ethernet HWaddr removed-for-privacy inet6 addr: removed-for-privacy/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:518 errors:0 dropped:0 overruns:0 frame:0 TX packets:510 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:196242 (191.6 KiB) TX bytes:52425 (51.1 KiB)

SEO title tag and earning a high rank on search engines [closed]

- by Josh White

Possible Duplicate: What are the best ways to increase your site's position in Google? One of the most basic SEO techiniques is including accurate description below 64 characters in the tags of each page. I was wondering if is considered ethical SEO to set up the contents based on a search keyword for example. So if the user searches for 'apples pictures' for example, then the title of the webpage would be 'apple pictures'. Note that the search keywords accurately describe my website contents because the title will always relate to the body of the webpage and 85-90% of the terms searched for will return corresponding results. Is this considered a good seo practice and is it ethical? Also, can someone explain what the idea is behind "linking"? I read somewhere that it is a good seo practice to link other websites and it is good when other websites link you. Does this mean that I should include as many links to other websites as possible (that are somehow relevant to my websites goal), also if I joined forums/services and posted my website url in the signature, would that still be considered other websites linking me?

WMV file won't play in Windows Media Player

- by user1053768

I have a .wmv file I uploaded to my website. When I click the link to the video, the video plays in Windows Media Player without any problems. However, on some systems when the user clicks the link, Windows Media Player gives them the error: Window Media Player cannot play the file. The player might not support the file type or might not support the codec that was used to compress the file All I did was copy the video to the server and store the URL in a database. Why are users getting this error? How can I fix it?

Wget site mirror, links with rel="<content>" not followed

- by Pacifika

Whilst creating a site mirror using wget 1.12 on Ubuntu links with a rel attribute set are not downloaded: <a href="link" rel="tag">text</a> Rel="tag" is a microformat (By adding rel="tag" to a hyperlink, a page indicates that the destination of that hyperlink is an author-designated "tag" (or keyword/subject) for the current page). My WordPress theme uses this for link to tags, so 99% of the site is ignored. Edit: it turns out all my permalinks use rel="bookmark" and are skipped as well. I'm using the following wget command (this ignores robots.txt and also follows nofollow links): wget -mkp -e robots=off http://site How do I make wget follow links with rel set?

Second network card configuration not working.

Run a command from Windows 7 Start Menu

- by Abhijeet Patel

I'm trying to run commands such as "cmd.exe", "appwiz.cpl" etc by typing it in the Search box of the Start Menu in Windows 7 (x86). I'm able to do this just fine in Vista. After typing in "cmd" I notice that I see a link to "Programs" in the start menu so it seems that "cmd" is being recognized but when I click on "Programs" link which is shown,I get the following message. "These files can't be opened. Your internet security settings prevented one or more files from being opened" P.S. - I'm not looking for enabling the "Run" command to show in the Start Menu Any help would be much appreciated

How to fix this navigation issue in my site?

- by David

First off I use webs.com for the creation of my site. I have a very basic layout. List of links of the left and content on the right with a heading up top. Now in my list of links every link is an article that I wrote, I have about 25 links going down the left hand side of my site. Problem is when I try out new themes that support horizontal navigation as opposed to vertical navigation I get either a messy overflow of links Or a link called "more" which lists the rest of the articles in a drop down-list across my site. What I wish I had was a simple horizontal navigation like" "home, about, articles" and when the user clicks on articles it would then bring them to a page containing all my articles there. I would prefer it to be in a table like display. That way is not a long list. Anyways any ideas on how I can fix this issue im having? Please let me know if you need more information.

Need to hookup HP dv7-3085dx with Nvidia GeForce GT 230M to my Dell 30 inch LCD 3007WFP at max resol

- by user14660

I recently bought an HP laptop (dv7-3085dx) (http://reviews.cnet.com/laptops/hp-pavilion-dv7-3085dx/4505-3121_7-33776108.html) which is supposed to have a pretty good video card (NVIDIA GeForce GT 230M). The card is supposed to output a max resolution of 2560x1600 which is also the max resolution of my monitor (http://www.ubergizmo.com/15/archives/2006/02/dell_3007wfp_on_dell_2001fp_action_8_megapixel_desktop.html). Now I bought an HDMI to dual link dvi (http://www.amazon.com/gp/product/B002KKLYDK/ref=oss_product) cable...this is after Best Buy's 70 dollar hdmi to dvi (perhaps it was 'single' link?) didn't give me the best resolution. In windows 7, when I try to set the max resolution for my 30 in monitor, I only get 1280x800...which is absurd. The monitor is great, I love the laptop and the video card supposedly supports such resolutions. So I can't figure out why I'm not getting better resolution (by the way, when i "detect" my monitor in windows 7, it is shown correctly as DELL 3007WFP!).

Add "secure" in cookie by httpd server

- by Abhishek

How do I have to configure my httpd server to add "Secure" in the cookies? I tried the one in the below link, http://blog.modsecurity.org/2008/12/fixing-both-missing-httponly-and-secure-cookie-flags.html but this did not seem to be working. I inspected the cookie via firebug and found that the cookies have "HttpOnly" but not "Secure". I double checked the configurations and they the same as mentioned in the link. I also noticed that the server response time goes bit high when doing it by mod_security. Is there a better way to do it? Any ideas or pointers to configurations would be helpful

I've found two methods: 1. The StackOverflow Method Create a new local html file with just the links eg <a href="http://podcast.cbc.ca/mp3/sundayeditionstream_20081125_9524.mp3">Sunday Edition 25Nov2008</a> Open the file in the browser, right click the link and File Save Link As. 2. The SuperUser Method Install the Firefox addin Iget. (Be sure to use the right version for your Firefox version.) Tools Downloads Enter url in field. Are there any other ways?

How to make Google recognize language for a multilingual website?

- by Julien Fouilhé

Few weeks ago, I implemented translation functionality for the website of my company. The website is now available in french and english and I did look on the internet the best way to do if we want to do not lose any ranking and to have our pages on Google. Here is what I did: I did set a response header: Content-Language:en and Content-Language:fr My URLs are formatted as: http://www.website.com/en/... and http://www.website.com/fr/... My html tag is set with a lang attribute: <html lang="en"> and <html lang="fr"> There is a <link rel="alternate" hreflang="en" href="EnglishPageUrl"> on french pages and a <link rel="alternate" hreflang="en" href="frenchPageUrl"> on english pages. But Google keeps referring to some english pages when I'm doing a search on french engine, knowing that the website was first only available in english. Is that normal? Do I have to wait still, it has been now almost one month, I thought it would be okay...? Thank you.

Lead Programmer definition clarification

- by Junaid

I am working on PHP and MySQL based web application for more than 5 years now. I started my career from Intern - Jr Developer - Software Developer - Sr. Software Engineer [Team Lead] that's what I am nowadays. I was looking at the link at Wikipedia regarding who is a lead programmer. The link states the following: A lead programmer is a software engineer in charge of one or more software projects. Alternative titles include Development Lead, Technical Lead, Senior Software Engineer, Software Design Engineer Lead (SDE Lead), Software Manager, or Senior Applications Developer. When primarily contributing in a high-level enterprise software design role, the title Software Architect (or similar) is often used. All of these titles can have different meanings depending on the context. My current job responsibilities are more or less like a Development Lead and to some extent near Software Architect because I usually design the core structure of new products and managing 2-3 project simultaneously and in the meantime involved in assisting other teams regarding the structural design of their projects, I am usually on call with clients along with project managers, I code most of the time when my team stuck somewhere / workload / integrating some third party API and etc. Primary reason of this writing is to know if I qualify for a Development Lead Title? in accordance with my above mentioned job descriptions?

Chrome drag and drop download links

- by Brad

In Chrome, I used to be able to take a link to a file and just drag to a folder on my system. Chrome would then download whatever resource was at the URL for the link and put it into the folder dropped into. This was particularly handy when using Gmail. If there was an attachment, I could just click and drag it into a folder, and Chrome would download it for me to the correct place. Now I have to hit download, and then drag from the download bar when it is finished. Has this feature been removed? Is there any way to bring it back?

HTTP resource caching / fetching

- by Bobby Jack

I'm trying to optimise a page, and I'm seeing some strange behaviour. Each time I click on a link to the page, all resources are fetched from the server, responding with 200s. However, when I refresh the page (specifically, F5 in Firefox), all resources return a 304 and - of course - the page loads much faster as a result. The main page returns a 200 in both cases. In the refresh case, If-Modified-Since headers are sent with the requests to the resources. However, in the 'clicking a link' case, they are not. What's the reason for that, and can I control it?

Second monitor not detected

- by Gabriel

Hi I have two VGA monitors, my GPU is ATI PowerColor 6850 which has two DVI slots, I use adapters for both VGA monitors. If I connect any the two monitors in the first slot it will work right away (along the plugin confirmation sound). And if I connect any of both monitors to the second slot I won't get anything, nor a signal or confirmation sound. I also tried auto detecting via Catalyst Control Center and Windows Desktop Resolution. I have the latest drivers installed. EDIT: I found this on the Spec Description: Display Connectors DL-DVI-I/SL-DVI-D And in NewEgg: 2 x DVI (1 Single Link, 1 Dual Link) Could this have anything to do with my issue?

route http and ssh traffic normally, everything else via vpn tunnel

- by Normadize

I've read quite a bit and am close, I feel, and I'm pulling my hair out ... please help! I have an OpenVPN cliend whose server sets local routes and also changes the default gw (I know I can prevent that with --route-nopull). I'd like to have all outgoing http and ssh traffic via the local gw, and everything else via the vpn. Local IP is 192.168.1.6/24, gw 192.168.1.1. OpenVPN local IP is 10.102.1.6/32, gw 192.168.1.5 OpenVPN server is at {OPENVPN_SERVER_IP} Here's the route table after openvpn connection: # ip route show table main 0.0.0.0/1 via 10.102.1.5 dev tun0 default via 192.168.1.1 dev eth0 proto static 10.102.1.1 via 10.102.1.5 dev tun0 10.102.1.5 dev tun0 proto kernel scope link src 10.102.1.6 {OPENVPN_SERVER_IP} via 192.168.1.1 dev eth0 128.0.0.0/1 via 10.102.1.5 dev tun0 169.254.0.0/16 dev eth0 scope link metric 1000 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.6 metric 1 This makes all packets go via to the VPN tunnel except those destined for 192.168.1.0/24. Doing wget -qO- http://echoip.org shows the vpn server's address, as expected, the packets have 10.102.1.6 as source address (the vpn local ip), and are routed via tun0 ... as reported by tcpdump -i tun0 (tcpdump -i eth0 sees none of this traffic). What I tried was: create a 2nd routing table holding the 192.168.1.6/24 routing info (copied from the main table above) add an iptables -t mangle -I PREROUTING rule to mark packets destined for port 80 add an ip rule to match on the mangled packet and point it to the 2nd routing table add an ip rule for to 192.168.1.6 and from 192.168.1.6 to point to the 2nd routing table (though this is superfluous) changed the ipv4 filter validation to none in net.ipv4.conf.tun0.rp_filter=0 and net.ipv4.conf.eth0.rp_filter=0 I also tried an iptables mangle output rule, iptables nat prerouting rule. It still fails and I'm not sure what I'm missing: iptables mangle prerouting: packet still goes via vpn iptables mangle output: packet times out Is it not the case that to achieve what I want, then when doing wget http://echoip.org I should change the packet's source address to 192.168.1.6 before routing it off? But if I do that, the response from the http server would be routed back to 192.168.1.6 and wget would not see it as it is still bound to tun0 (the vpn interface)? Can a kind soul please help? What commands would you execute after the openvpn connects to achieve what I want? Looking forward to hair regrowth ...

XboxMP Helps You Find Multiplayer Games for the Xbox

- by Jason Fitzpatrick

Searching for the perfect versus or cooperative Xbox multiplayer game can be challenging–the game publisher says it plays four but what exactly does that mean? XboxMP catalogs games with detailed breakdowns of what the multiplayer experience actually entails. You can search first generation Xbox games, Xbox 360 games, and Xbox Live Arcade games with a variety of detailed criteria including the number of players it supports for local, system link, and online play (it may be a deal breaker, for example, that the only way to play the game with 4 players is to have two Xboxes or an Xbox live account). In addition to the multiplayer game data each game listing also includes addition information about the general game play including peripheral support and other features.

recent unreliable wireless connection

- by gabkdlly

Recently, my internet connection over wireless ( via a Netgear KWGR614 router ) has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista, nor on a Desktop running Windows 7 ( this machine is connected with an ethernet cable ). The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP or WPA to encrypt the wireless network. Is it possible that someone is jamming my signal ?

ata error: UnrecovData Handshk

- by Aaron Digulla

I just saw this message in my log (openSUSE 11.3, Linux 2.6.36.2): ata6.00: exception Emask 0x10 SAct 0x1 SErr 0x400100 action 0x6 frozen ata6.00: irq_stat 0x08000000, interface fatal error ata6: SError: { UnrecovData Handshk } ata6.00: failed command: WRITE FPDMA QUEUED ata6.00: cmd 61/58:00:9f:69:00/00:00:00:00:00/40 tag 0 ncq 45056 out res 40/00:04:9f:69:00/00:00:00:00:00/40 Emask 0x10 (ATA bus error) ata6.00: status: { DRDY } ata6: hard resetting link ata6: SATA link up 3.0 Gbps (SStatus 123 SControl 300) ata6.00: configured for UDMA/133 ata6: EH complete Two questions: Which disk caused the error? I search /sys and /proc but couldn't find a way to map ata6 to a device (/dev/sdaXY) When such an error happens, does Linux retry the disk operation? Or do I have a corrupt filesystem?
