• Shared to Dedicated or Amazon CloudFront to improve performances and keep secured?

  - by user978548

  I have a Wordpress which currently takes about 1.8s to 2.5s for the home page to completely load in my country. The page weight is about 700Ko (static content included). In order to increase performances, I'm considering two solutions: Switching to a dedicated host. Using amazon s3 cloudfront to serve static contents. My current shared hosting have servers in a neighboring country but not exactly in mine, and both amazon and the dedicated hosting have some, so that's already an advantage. So considering all that, I still have three questions remaining: Currently having a low traffic (100 unique visitors/days, but growing) will it make a huge difference between my shared hosting and a dedicated server ? Knowing that I already use a cookie-less domain to deliver static contents (but using a redirection to the same server), would using amazon s3 make a real difference ? Talking about the cons of dedicated vs amazon s3, if I choose for the dedicated server something like Ubuntu server and do daily package updates and have only port 80 open, would it be sufficient in terms of security (in comparison with my current shared hosting which manage everything for me) ?

• How to SEO Optimize Javascript Image Loader?

  - by skibulk

  I am building an image-centric catalog website. It catalogs collectible gaming cards numbering 100,000+ pages. Competitor sites recieve millions of hits each month, so with the possibility of excessive traffic, I need to moderate image bandwidth while also optimizing for image SEO. I'm looking for some tips on doing so. Each page on the site features one card with appropriate tags and descriptions. There are however four images for each card - one on matte cardstock, one on foil cardstock, one digital, and one digital foil. In a world with unlimited bandwidth and no-wait page loads, I'd simply embed all four images on the main product page with titles, alt tags, and captions to rank them according to their version keyword. In reality a javascript gallery image loader seems appropriate. Here is a simplified example of my current code. Would this affect SEO in any way? Should I be doing anything differently? Note that I don't want to create a page for each image as I'd have to duplicate the card tags and descriptions on each one, diluting PR for the main page. Thanks for any insight! <script type="text/javascript"> document.write(' <img src="thumbnail1.jpg" data-src="version1.jpg"> <img src="thumbnail2.jpg" data-src="version2.jpg"> <img src="thumbnail3.jpg" data-src="version3.jpg"> <img src="thumbnail4.jpg" data-src="version4.jpg"> '); </script> <noscript> <img src="version1.jpg"> <img src="version2.jpg"> <img src="version3.jpg"> <img src="version4.jpg"> </noscript>

• How can I pass referrer header from my https domain to http domains?

  - by nutcracker

  My website is 100% https. I have links to other http domains. The referrer header is not set when linking from a https page to a http page. From http://en.wikipedia.org/wiki/HTTP_referrer If a website is accessed from a HTTP Secure (HTTPS) connection and a link points to anywhere except another secure location, then the referer field is not sent. I would prefer that other domains can see the referrer so that they know that traffic comes from my domain. Is there a way to force this header or is there another solution? Update I've done some basic testing using a redirect: http page -- link to http --> 301 redirect --> http page = referrer intact https page -- link to https --> 301 redirect --> http page = referrer blank https page -- link to http --> 301 redirect --> http page = referrer blank https page -- link to http --> 302 redirect --> http page = referrer blank The referrer is lost when linking from a https page to a http redirect page on my own domain. So there is no referrer on the redirect.

• How can I tell GoogleBot that a subdirectory is now a subdomain?

  - by cwd

  I had about a million pages of a catalog indexed under a subdirectory, and now that's moved to a subdomain. GoogleBot is crawling each one of them and getting a 301 redirect to the new location. Even though I have set up the redirect rule in the apache sites-enabled configuration file, (i.e. it's early on when apache does the redirect - PHP is not even getting loaded), even though I have done that, the server isn't handling the load well. GoogleBot is making around 5 requests per second, and on top of my normal traffic that is hiking up the CPU for a few hours at a time. I checked in Webmaster Tools and the corresponding documentation for a way to let Google know that the content had been moved from a subdirectory to a subdomain, but with little luck. Basically the most helpful thing I saw said to just send 301 headers for the new location. How can I tell GoogleBot that a subdirectory is now a subdomain? If that is not an option, how can I more efficiently send 301 redirects out for a particular subdomain? I was thinking perhaps the Nginx server but I'm not sure that I can run both Apache and Nginx side by side on port 80 for different subdomains.

• Basic Google Analytics Click Tracking and/or Overview

  - by Alan Storm

  This is a really basic Google Analytics question. Apologies in advance if it's not appropriate here, but I've had a lot of luck on Stack Overflow and this seems like the best Stack Exchange site for a question like this. I'm trying to understand how Google Analytics goals work, or if they're the right feature to be using for my situation. Most of the documentation I find online refers to the old version of the UI, not the new one. I have a website, let's call is blog.example.com. This website drives traffic to an ecommerce store, let's call that store.example2.com. I want to get reports on which links from blog.example.com are being clicked through leading to store.example2.com. How do you do this in Google analytics? Are goals the right area to be looking? Do I setup the goals on store.example2.com or blog.example.com? Or both? Is there any canonical user guide (free or paid) that covers how this works? I'm a competent programmer, but it's years since I dealt with conversion tracking on any serious level, and we've progressed well beyond my frozen caveman pixel tracking knowledge. Thanks in advance

• Antenna Aligner Part 3: Kaspersky

  - by Chris George

  Quick one today. Since starting this project, I've been encountering times where Nomad fails to build my app. It would then take repeated attempts at building to then see a build go through successfully. Rob, who works on Nomad at Red Gate, investigated this and it showed that certain parts of the message required to trigger the 'cloud build' were not getting through to the Nomad app, causing the HTTP connection to stall until timeout. After much scratching heads, it turns out that the Kaspersky Internet Security system I have installed on my laptop at home, was being very aggressive and was causing the problem. Perhaps it's trying to protect me from myself? Anyway, we came up with an interim solution why the Nomad guys investigate with Kaspersky by setting Visual Studio to be a trusted application with the Kaspersky settings and setting it to not scan network traffic. Hey presto! This worked and I have not had a single build problem since (other than losing internet connection, or that embarrassing moment when you blame everyone else then realise you've accidentally switched off your wireless on the laptop).

• Analytics - Where do my drop offs go?

  - by BadCash

  I have a website set up with Google Analytics (through the Wordpress plugin "Google Analytics for WordPress" by Joos de Valk). When I check out the visitors flow in Google Analytics, it shows something like this: (home) - 43% drop-offs /page-2/ - 10% drop-offs ... etc ... I have also set up events for external links. My main "goal" of the website is to drive traffic to my Android app on Google Play, so I have a couple of different links to that that are all set up as events. Everything seems to be working, my events show up when I go to Content - Events in Google Analytics. However, it seems to me that some percentage of the users that are reported as "drop-offs" in fact have clicked on one of the external links. But there's no info about the reason of those drop-offs in the Visitors flow-chart. I can of course check out each specific event category, event action and set "other" to Content/Page, which (I guess) shows the number of visitors who triggered a specific event on a specific page. It just seems like such a complicated way of going about this! So, is there a way to get a more detailed picture, including events, in the Visitors flow chart? Something like: (home) - 43% drop-offs Event Action: "Google Play"=50%, "Youtube"=10%, (not set)=40%

• Google suddenly only indexes https and not http

  - by spender

  So all of a sudden, searches for our site "radiotuna" give out the result as an HTTPS link. https://www.google.com/?q=radiotuna#hl=en&safe=off&output=search&sclient=psy-ab&q=radiotuna&oq=radiotuna&gs_l=hp.12...0.0.0.3499.0.0.0.0.0.0.0.0..0.0.les%3B..0.0...1c.LnOvBvgDOBk&pbx=1&bav=on.2,or.r_gc.r_pw.r_qf.&fp=177c7ff705652ec3&biw=1366&bih=602 We only use https for the download of two specific files (these urls are resources used for autoupdate functionality of an app we distribute). All other parts of the site should be served over http. We wouldn't like to see any other traffic over https, nor any of our site links to appear in search engines as https. I'd like to address this issue. It seems that the following solutions are available: hand out an https specific robots.txt as such: User-agent: * Disallow: / and/or at app-level, 301 permanent redirect all requests (except the two above) to HTTP if they come in as HTTPS. My concern with the robots method is that, say (for some reason) google decided not to index http pages, disallowing https pages might mean that google has nothing left to index with disastrous consequences for our ranking. This means I'm inclined to go with a 301 redirect. Any thoughts?

• Defining work days and work time

  - by user2553268

  I'm working on development of SMS parking software, and I'm stuck at one point for a month... I need to implement periods of payment (or work time, of a work day, if you will). Here's the problem: For an example, traffic wardens work from Monday to Saturday. From Monday to Friday, the work times are from 07:00 to 21:00, and on Saturday, the work time is from 07:00 to 14:00. The project request was, that the customer can pay parking by SMS unlimited, which I did, but didn't implement this logic. I started with making a table for this periods of payment, it consists of: dayofweek (INT, for use with mysql function DAYOFWEEK, to tell me which day in week is the current date), work_start and work_stop (DATETIME, for defining starting and ending the work day), but I'm unsure if I should use DATETIME, beacuse of the date, or should I use only TIME. The idea is this: If you send an SMS, at 20:50, Monday, it should be valid until 07:50, Tuesday (it's payed by the hour). Extending the time of payment, regarding the work time in week. Currently, it works with extending time by the hour without this rule. Really would use some help, or some ideas, I'm stuck with this for quite some time...

• Exchange 2010 Deployment Notes - ISA 2004 Server Issue

  - by BWCA

  An interesting ISA 2004 tidbit … While we were setting up our Exchange 2010 ActiveSync environment, we encountered a problem where we could not successfully telnet over port 443 from one of our ISA 2004 Servers to our Exchange 2010 Client Access Server Array. When we tried to telnet over port 443 from the ISA Server to the Client Access Server Array name, we would get a “Could not open connection to the host on port 443: Connect failed” error message. Also, when we used portqry over port 443 from the ISA Server to the Client Access Server Array name, we would get a “Error opening socket: 10065” and “No route to host” error messages. It was odd because we did not have any problems with using ping or tracert from the ISA Server to the Client Access Server Array and our firewall firewall policy was allowing 443 traffic to pass through. After some troubleshooting, we were able to telnet and use portqry over port 443 successfully if we stopped the Microsoft Firewall service on the ISA 2004 Server.  So, it was strictly a problem with ISA.  Eventually, we were able to isolate the problem to a ISA 2004 Server System Policy setting as shown below (to modify the System Policy, right-click Firewall Policy and click Edit System Policy). Under the Diagnostics Services – HTTP Connectivity verifiers Configuration Group, you need to enable the configuration group under the General tab to resolve the problem.  After we enabled the setting, we no longer had a problem.

• Trigger IP ban based on request of given file?

  - by Mike Atlas

  I run a website where "x.php" was known to have vulnerabilities. The vulnerability has been fixed and I don't have "x.php" on my site anymore. As such with major public vulnerabilities, it seems script kiddies around are running tools that hitting my site looking for "x.php" in the entire structure of the site - constantly, 24/7. This is wasted bandwidth, traffic and load that I don't really need. Is there a way to trigger a time-based (or permanent) ban to an IP address that tries to access "x.php" anywhere on my site? Perhaps I need a custom 404 PHP page that captures the fact that the request was for "x.php" and then that triggers the ban? How can I do that? Thanks! EDIT: I should add that part of hardening my site, I've started using ZBBlock: This php security script is designed to detect certain behaviors detrimental to websites, or known bad addresses attempting to access your site. It then will send the bad robot (usually) or hacker an authentic 403 FORBIDDEN page with a description of what the problem was. If the attacker persists, then they will be served up a permanently reccurring 503 OVERLOAD message with a 24 hour timeout. But ZBBlock doesn't do quite exactly what I want to do, it does help with other spam/script/hack blocking.

• How do I trust an off site application

  - by Pieter

  I need to implement something similar to a license server. This will have to be installed off site at the customers' location and needs to communicate with other applications at the customers' site (the applications that use the licenses) and an application running in our hosting center (for reporting and getting license information). My question is how to set this up in a way I can trust that: The license server is really our application and not something that just simulates it; and There is no "man in the middle" (i.e. a proxy or something that alters the traffic). The first thing I thought of was to use with client certificates and that would solve at least 2. However, what I'm worried about is that someone just decompiles (this is build in .NET) the license server, alters some logic and recompiles it. This would be hard to detect from both connecting applications. This doesn't have to be absolutely secure since we have a limited number of customers whom we have a trust relationship with. However, I do want to make it more difficult than a simple decompile/recompile of the license server. I primarily want to protect against an employee or nephew of the boss trying to be smart.

• How to handle new domain names?

  - by michael

  I have a new product which I'll call a pen ink reloader. I have a website using my products name, for example, www.inkywink.com which I want to have accessed by searches for keywords such as "pen ink", "pen out of ink" "ink for pens" etc. , since nobody knows that a pen ink reloader exists. I see that its quite difficult to get on front page for these keywords since they have lots of competition. However I notice that the exact phrases I want to rank highly for are available as domains. I purchase "www.penink.com" and "penoutofink.com" which for arguments sake are highly searched and the perfect keywords to get eyes on my money site www.inkywink.com . Two questions: 1. What is my best option to leverage those names so that they appear near top of searches so that I can get traffic to my money site? Do I just have them redirect 301 to inkywink.com or should I create small original content on each with links to my main site? 2. If I just have them redirected to inkywink.com, am I able to use keywords in metatag and headers for each site separately or do they all automatically obtain the same headers and tags as the site to which theyre redirected ? Thanks to anyone who can help as I'm a real newbie to all this.

• High Performance SQL Views Using WITH(NOLOCK)

  - by gt0084e1

  Every now and then you find a simple way to make everything much faster. We often find customers creating data warehouses or OLAP cubes even though they have a relatively small amount of data (a few gigs) compared to their server memory. If you have more server memory than the size of your database or working set, nearly any aggregate query should run in a second or less. In some situations there may be high traffic on from the transactional application and SQL server may wait for several other queries to run before giving you your results. The purpose of this is make sure you don’t get two versions of the truth. In an ATM system, you want to give the bank balance after the withdrawal, not before or you may get a very unhappy customer. So by default databases are rightly very conservative about this kind of thing. Unfortunately this split-second precision comes at a cost. The performance of the query may not be acceptable by today’s standards because the database has to maintain locks on the server. Fortunately, SQL Server gives you a simple way to ask for the current version of the data without the pending transactions. To better facilitate reporting, you can create a view that includes these directives. CREATE VIEW CategoriesAndProducts AS SELECT * FROM dbo.Categories WITH(NOLOCK) INNER JOIN dbo.Products WITH(NOLOCK) ON dbo.Categories.CategoryID = dbo.Products.CategoryID In some cases quires that are taking minutes end up taking seconds. Much easier than moving the data to a separate database and it’s still pretty much real time give or take a few milliseconds. You’ve been warned not to use this for bank balances though.

• Providing SSH tunnling, what to think about when configuring Ubuntu Server

  - by bigbadonk420

  Recently I've considered, mostly as a pet project, to set up accounts for a closed group of users via SSH to my box with the purpose of SSH tunnling things like web traffic -- some of it for friends that live abroad and perhaps also to help some people bypass national censorship. There's some things I imagine that I need to do, such as: Disabling shell access by setting the shell to /bin/false or similar. Get some software that can track bandwidth usage on a per-user basis historically Make sure that each user can only use a certain amount of bandwidth. The reason I'm posting here to begin with is to look around and get some pointers regarding what kind of things I should read up on, as well as hearing if there are any software recommendations for doing what I'm trying to do. I already know a bit since I've actually gotten SSH tunnling up and running already, I just don't feel like letting it loose to other people without restrictions and some basic monitoring. I'm primarily trying to learn here, so if you think this is a Very Bad Idea (or if you have a better idea on how to do this) then by all means say so, but please include some information on how to do it :) (I'm also open to trying things like OpenVPN but it seems really hard to set up, also I've heard SSH more often works in locked down environments)

• How to document requirements for an API systematically?

  - by Heinrich

  I am currently working on a project, where I have to analyze the requirements of two given IT systems, that use cloud computing, for a Cloud API. In other words, I have to analyze what requirements these systems have for a Cloud API, such that they would be able to switch it, while being able to accomplish their current goals. Let me give you an example for some informal requirements of Project A: When starting virtual machines in the cloud through the API, it must be possible to specify the memory size, CPU type, operating system and a SSH key for the root user. It must be possible to monitor the inbound and outbound network traffic per hour per virtual machine. The API must support the assignment of public IPs to a virtual machine and the retrieval of the public IPs. ... In a later stage of the project I will analyze some Cloud Computing standards that standardize cloud APIs to find out where possible shortcomings in the current standards are. A finding could and will probably be, that a certain standard does not support monitoring resource usage and thus is not currently usable. I am currently trying to find a way to systematically write down and classify my requirements. I feel that the way I currently have them written down (like the three points above) is too informal. I have read in a couple of requirements enineering and software architecture books, but they all focus too much on details and implementation. I do really only care about the functionalities provided through the API/interface and I don't think UML diagrams etc. are the right choice for me. I think currently the requirements that I collected can be described as user stories, but is that already enough for a sophisticated requirements analysis? Probably I should go "one level deeper" ... Any advice/learning resources for me?

• Site failing randomly - could it be Cloudflare or something weird in the JS?

  - by James

  I've been working on a simple site that uses javascript to fade through some fullscreen background images as well as some other simple animations. I've tested the site on Chrome, Safari, FF and Opera on OSX, IE8+ on Win7 and Chrome & FF on Ubuntu and everything looks as I'd expect it to. However, I've had reports of the site failing to load (stops at the stage where the background fades up) on Safari and Chrome on OSX and Win. I can't replicate this on any setup so I'm finding it impossible to troubleshoot. Google's instant preview shows the site fine as does most of the options at browsershots.org so I'm really scratching my head. I'm running the site's traffic through Cloudflare and I'm wondering whether anyone can see (or knows from other sites) why Cloudflare might be mangling the JS or causing a problem somehow (I don't get any errors in the JS error console). Of course, if you can replicate the problem on your machine and can suggest an area to look at that would be amazing but I'm hoping that, like me, you don't see any problem with the site! Here's the site: http://www.bighornrevelstoke.com Thanks, James

• With Google Analytics, is it possible to check a specific page in Multi-Channel conversion attribution?

  - by Emmett R.

  I'm somewhat new to Google Analytics, and I'm trying to track all conversions that are assisted by a particular landing page, because I don't expect an instant purchase. I have e-commerce tracking set up. Due to the constraints of the associated ad campaign, I can't include the source/medium code in the url when people go to the landing page, and all of my traffic to the landing page is likely to be direct, so I'm not sure how to tell Multi-Channel marketing that it's a significant page. I know how to add events to a page, but I'm still figuring out what they can and cannot do. Would creating a redirect from the landing url to an identical url+source/medium code work? Any advice on how to accomplish this would be greatly appreciated. Tracking the final sale conversion is not the issue. Ecommerce reporting is functioning just fine on the site. I just want to report the landing page as an assist, whenever it shows up in the funnel, and I need to be able to do that across multiple visits.

• How do I find information on who links to my sites?

  - by bobdobbs

  I'm trying to figure out if there's a free way to get information on backlinks to my site. I've had webmaster tools and google analytics set up for years. But I can't find access to data about site backlinks in either toolset. Webmaster tools, under 'traffic'-'links to your site' gives me the same message for all of my sites: "No data available". I haven't been able to find anything in GA that gives any information on backlinks. I've heard of using "links:" as an operator in google search, but for each of my sites, this returns either zero or very few results in cases when I know I have many backlinks. Most of the links simple aren't shown. My thinking is that google maintains a graph of who links to my site, so I figured that they might let me see it. But I can't figure out how. I've found this tool on a spammy website: http://www.backlinkwatch.com. It offers more data than google on my backlines, and offers more results in exchange for a paid subscription. The data it offers for free looks good, but the results are limited and the site has popups and obnoxious ads. So, in short: how do I get data on who links to me? Is there a free way?

• SMTP server to deliver mail to Rails app, how?

  - by Gunchars

  all, this is my first question and I hope I chose the right place to post it. Here's what I need help with: I've been looking for this all day and I'm having a hard time finding a SMTP mail server that would fit the following criteria: lightweight, does one thing and does it good is able to route and deliver local mail to a Rails application The second point could be accomplished in any number of ways. I'm running a VPS, so I have full freedom in how to implement this. It could, for example, put messages straight in the db, pipe them to a helper program that would then process them accordingly or also save messages in a mbox file and run a script after every received message. I'm building a small site so the traffic is not going to be a problem. If there are alternative ways to deliver messages to a Rails app, I'd gladly hear about them. Thank you. EDIT: After long searching, I think I've found what I was looking for. Exim is a mail server that can deliver local mail to pipes. Also, Rails 3 and ActionMailer can make it really easy to process the incoming mail.

• Do large number of internal broken links affect SEO?

  - by TheBigK

  We've a WordPress blog and had disqus plugin in stalled for several months. Around late August this year, the plugin created a ton of URLs that linked to non-existent location on our website. For example - Correct URL: domain.com/correct-URL/ Disqus created - domain.com/correct-URL/344322/ - Throws 404 domain.com/correct-URL/433466/ - Throws 404 So essentially, Google found a LARGE number of broken links that pointed to unknown locations on our own domain. As the count of those errors (404) rose, our site suffered massive drop in traffic and crawl rate dropped to 10% of what it was earlier. I wish to know - Can large number of (we've over 99k of them) internal broken links cause rankings to drop? I've fixed the issue in one go by creating 301 redirects for each bad URL to correct URL and removing disqus. Google however drops the count by ~1000 daily, as I mark errors as 'fixed' in Google Webmaster Tools. Is there any way to speed this up? Should I setup custom crawl rate to 'Fast' in GWT to make Google crawl our website faster? I'd appreciate your inputs and experience sharing.

  over the weekend I updated my computer to Windows 8. So far Ubuntu One was running smoothly, but ever since the update (clean, new install) Ubuntu doesn't sync any more. In Windows 7 it would start to sync at full internet speed as soon as I drop a file. But now in Windows 8, as soon as I drop a new file into the Ubuntu One folder, CPU usage goes up to about 50 % and no network traffic occurs. This stays like that for a couple of minutes, CPU usage goes back to normal and then the client says that all is in sync - which isn't true. Is it too early for Windows 8? Do others have the same problem or is there something I can do about it? I try a couple of different things, and realized that if the file size is 20 MB the files get uploaded. The original file was 1.5 GB. I also didn't work with 200, 100 and 50 MB large files. But even with 20 MB large files, the upload is very slow and not steady. The log give plenty of this error: - twisted - ERROR - Failure: exceptions.TypeError About which I don't know the meaning. By the way, the account works just fine on the Ubuntu 12.04 partition. Any help is greatly appreciated. -Peter

• Is it possible to have multiple subdomains point to the same Blogger blog?

  - by cclark

  For our application we want to have a status page which is hosted outside of the rest of our infrastructure so in case there are issues in our data center we can post updates for our users and our users will be able to access them. We registered a blog on Blogger and set it up with xyzstatus.blogspot.com and status.xyz.com. Everything seems to work fine. We need to perform some maintenance at our datacenter which will sever all connectivity so we're unable to have a redirect using nginx or apache. We'd like to do this with a short TTL CNAME DNS entry. Ideally www.xyz.com and app.xyz.com could be CNAMEd to status.xyz.com. When I setup the CNAME and go to that URL I get a Google broken robot 404 page. I figure I must need to let Google know it should associate traffic to www.xyz.com and app.xyz.com to the blog served up by status.xyz.com. But I can't see anywhere to do this in Blogger. Does anyone know if this is possible?
