  • Am I correctly handling duplicate URLs for my homepage?

    - by Rob Goldstein
    I own a Job Search site named www.conservationjobboard.com and have a concern about how the domain is viewed by search engines. The issue is that when the site was first designed, the default page was left as default.php, but the homepage was actually JobBoard.php. To handle this, the default.php page performed a redirect to the JobBoard.php file when www.conservationjobboard.com/ was requested. The main problem resulted because the redirect was a temporary redirect causing search engines to index conservationjobboard.com/ and conservationjobboard.com/JobBoard.php as 2 separate pages. This has since been corrected to use the .htaccess file so that JobBoard.php is now the default file for the root directory eliminating the need for the redirect. Problem is that search engines still show both URL's in search results (one including JobBoard.php and one that ends with /). Another potential problem is that some of my early backlinks are to conservationjobboard.com/JobBoard.php while the rest are to conservationjobboard.com The 2 outstanding questions are as follows: 1. Is my domain still being penalized by search engines like Google for having duplicate homepage URL's? 2. Are all of the back links to my homepage being considered as the same now or is the total number of back links being split between the 2 different URL's? If you think there are still issues with how we have this set-up, I was wondering if you could give me advice on what we should do differently. Thanks.

  • Why did numbered list stop working after I hit Enter?

    - by Michael Leach
    I have a numbered list like: 1.0 Excel 2010 1.1 Introduction to Excel 2010 1.1.A. A general overview of Excel 2010, geared towards beginners 1.1.B. There are 3 videos in this series I put the cursor at the end of the last line on 1.1.B and hit Enter. The next line should begin with 1.1.C but nothing appears when the cursor returns to the next line. Another example, if I put the cursor at the end of 1.1.A and hit enter, I should get a new 1.1.B and the original 1.1.B should be renamed to 1.1.C. After hitting enter, a new 1.1.B doesn't appear and the previous 1.1.B drops all the way to the next page. So the next bullet number that should come up doesn't come up. I tried Microsoft Fix It to reset the Registry and that didn't work either. This is very frustrating. Does anybody know how to fix this?

  • When to move into a CRM system?

    - by Dan
    I have a client that is currently managing around 5000+ contacts via Outlook. There is also a BES Express installation in place. There are a couple problems. First, there is a corrupt contact in there somewhere that is preventing either a cabled or over the air sync of the complete list to a blackberry. The second, is that it just seems to be getting a bit unruly. They currently have a license for ACT, which I'm trying to get them to move into, but at what number does the contact list need to be at to migrate away from using Outlook/Exchange and into a real CRM solution?

  • Difficulty in running Tomcat v7.0 with Eclipse Juno

    - by user1673718
    I get the following error when I run my JSP file in Eclipse-Juno with Tomcat v7: 'starting Tomcat v7.0 server at localhost' has encountered a problem. Port 8080 required by Tomcat v7.0 server at localhost is already in use. The server may already be running in another process, or a system process may be using the port. To start this server you will need to stop the other process or change the port number(s). I have Oracle 10g installed in my System. When I type "http://localhost:8080" it opens the Oracle 10g license agreement so I think Oracle 10g is already running in that port. To change the port of Tomcat I tried Google, which said to change the port in the "C:\Program Files\Apache Software Foundation\Apache Tomcat 7.0.14\conf\httpd.conf" file But at "C:\Program Files\Apache Software Foundation\Apache Tomcat 7.0.14\conf" there was no httpd.conf file. I only have "catalina.policy,catalina.properties,context,logging.properties,server,tomcat-users,web" files in that conf folder. I use windows XP.

  • adding keyboard shortcuts for OSX terminal or xterm

    - by I J
    Is there a way to add a keyboard shortcut for a terminal command in OSX. Basically most of the times i open the terminal app in MAC in order to ssh into a certain server foo. What I want to do is add a keyboard shortcut (say ^k) so that on a terminal when I do that, it runs "ssh foo" in the terminal. Thanks PS: I think if there is something for the xterm in linux then it should work for the terminal too. So this might not be an OSX specific question. PS2: I want the shortcut to do carriage return with the "ssh foo". If its just "ssh foo", then I can write an alias in .bashrc. My goal is to minimize the number of keystrokes I've to do at the end of the day.

  • Large invoice database structure and rendering

    - by user132624
    Our client has a MS SQL database that has 1 million customer invoice records in it. Using the database, our client wants its customers to be able to log into a frontend web site and then be able to view, modify and download their company’s invoices. Given the size of the database and the large number of customers who may log into the web site at any time, we are concerned about data base engine performance and web page invoice rendering performance. The 1 million invoice database is for just 90 days sales, so we will remove invoices over 90 days old from the database. Most of the invoices have multiple line items. We can easily convert our invoices into various data formats so for example it is easy for us to convert to and from SQL to XML with related schema and XSLT. Any data conversion would be done on another server so as not to burden the web interface server. We have tentatively decided to run the web site on a .NET Framework IIS web server using MS SQL on MS Azure. How would you suggest we structure our database for best performance? For example, should we put all the invoices of all customers located within the same 5 digit or 6 digit zip codes into the same table? Or could we set up a separate home directory for each customer on IIS and place each customer’s invoices in each customer’s home directory in XML format? And secondly what would you suggest would be the best method to render customer invoices on a web page and allow customers to modify for best performance? The ADO.net XML Data Set looks intriguing to us as a method, but we have never used it.

As an industry, we’ve spent many years analyzing all the data that’s been collected. Yes, that data has been invaluable in helping us make better decisions like where to open new stores, how to assort those stores, and how to price our products. But the recent advances in technology are now making it possible to analyze and deliver that data very quickly… fast enough to impact a potential sale in near real-time. Let me give you two examples. Salesmen in car dealerships get pretty good at sizing people up. When a potential customer walks in the door, it doesn’t take long for the salesman to figure out the revenue at stake. Is this person a real buyer, or just looking for a fun test drive? Will this person buy today or three months from now? Will this person opt for the expensive packages, or go bare bones? While the salesman certainly asks some leading questions, much of information is discerned through body language. But body language doesn’t translate very well over the web. Eloqua, which was acquired by Oracle earlier this year, reads internet body language. By tracking the behavior of the people visiting your web site, Eloqua categorizes visitors based on their propensity to buy. While Eloqua’s roots have been in B2B, we’ve been looking at leveraging the technology with ATG to target B2C. Knowing what sites were previously visited, how often the customer has been to your site recently, and how long they’ve spent searching can help understand where the customer is in their purchase journey. And knowing that bit of information may be enough to help close the deal with a real-time offer, follow-up email, or online customer service pop-up. This isn’t so different from the days gone by when the clerk behind the counter of the corner store noticed you were lingering in a particular aisle, so he walked over to help you compare two products and close the sale. You appreciated the personalized service, and he knew the value of the long-term relationship. Move that same concept into the digital world and you have Oracle’s CX Suite, a cloud-based offering of end-to-end customer experience tools, assembled primarily from acquisitions. Those tools are Oracle Marketing (Eloqua), Oracle Commerce (ATG, Endeca), Oracle Sales (Oracle CRM On Demand), Oracle Service (RightNow), Oracle Social (Collective Intellect, Vitrue, Involver), and Oracle Content (Fatwire). We are providing the glue that binds the CIO and CMO together to unleash synergies that drive the top-line higher, and by virtue of the cloud-approach, keep costs at bay. My second example of real-time marketing takes place in the store but leverages the concepts of Web marketing. In 1962 the decline of personalized service in retail began. Anyone know the significance of that year? That’s when Target, K-Mart, and Walmart each opened their first stores, and over the succeeding years the industry chose scale over personal service. No longer were you known as “Jane with the snotty kid so make sure we check her out fast,” but you suddenly became “time-starved female age 20-30 with kids.” I’m not saying that was a bad thing – it was the right thing for our industry at the time, and it enabled a huge amount of growth, cheaper prices, and more variety of products. But scale alone is no longer good enough. Today’s sophisticated consumer demands scale, experience, and personal attention. To some extent we’ve delivered that on websites via the magic of cookies, your willingness to log in, and sophisticated data analytics. What store manager wouldn’t love a report detailing all the visitors to his store, where they came from, and which products that examined? People trackers are getting more sophisticated, incorporating infrared, video analytics, and even face recognition. (Next time you walk in front on a mannequin, don’t be surprised if it’s looking back.) But the ultimate marketing conduit is the mobile phone. Since each mobile phone emits a unique number on WiFi networks, it becomes the cookie of the physical world. Assuming congress keeps privacy safeguards reasonable, we’ll have a win-win situation for both retailers and consumers. Retailers get to know more about the consumer’s purchase journey, and consumers get higher levels of service with the retailer. When I call my bank, a couple things happen before the call is connected. A reverse look-up on my phone number identifies me so my accounts can be retrieved from Siebel CRM. Then the system anticipates why I’m calling based on recent transactions. In this example, it sees that I was just charged a foreign currency fee, so it assumes that’s the reason I’m calling. It puts all the relevant information on the customer service rep’s screen as it connects the call. When I complain about the fee, the rep immediately sees I’m a great customer and I travel lots, so she suggests switching me to their traveler’s card that doesn’t have foreign transaction fees. That technology is powered by a product called Oracle Real-Time Decisions, a rules engine built to execute very quickly, basically in the time it takes the phone to ring once. So let’s combine the power of that product with our new-found mobile cookie and provide contextual customer interactions in real-time. Our first opportunity comes when a customer crosses a pre-defined geo-fence, typically a boundary around the store. Context is the key to our interaction: that’s the customer (known or anonymous), the time of day and day of week, and location. Thomas near the downtown store on a Wednesday at noon means he’s heading to lunch. If he were near the mall location on a Saturday morning, that’s a completely different context. But on his way to lunch, we’ll let Thomas know that we’ve got a new shipment of ASICS running shoes on display with a simple text message. We used the context to look-up Thomas’ past purchases and understood he was an avid runner. We used the fact that this was lunchtime to select the type of message, in this case an informational message instead of an offer. Thomas enters the store, phone in hand, and walks to the shoe department. He scans one of the new ASICS shoes using the convenient QR Codes we provided on the shelf-tags, but then he starts scanning low-end Nikes. Each scan is another opportunity to both learn from Thomas and potentially interact via another message. Since he historically buys low-end Nikes and keeps scanning them, he’s likely falling back into his old ways. Our marketing rules are currently set to move loyal customer to higher margin products. We could have set the dials to increase visit frequency, move overstocked items, increase basket size, or many other settings, but today we are trying to move Thomas to higher-margin products. We send Thomas another text message, this time it’s a personalized offer for 10% off ASICS good for 24 hours. Offering him a discount on Nikes would be throwing margin away since he buys those anyway. We are using our marketing dollars to change behavior that increases the long-term value of Thomas. He decides to buy the ASICS and scans the discount code on his phone at checkout. Checkout is yet another opportunity to interact with Thomas, so the transaction is sent back to Oracle RTD for evaluation. Since Thomas didn’t buy anything with the shoes, we’ll print a bounce-back coupon on the receipt offering 30% off ASICS socks if he returns within seven days. We have successfully started moving Thomas from low-margin to high-margin products. In both of these marketing scenarios, we are able to leverage data in near real-time to decide how best to interact with the customer and lead to an increase in the lifetime value of the customer. The key here is acting at the moment the customer shows interest using the context of the situation. We aren’t pushing random products at haphazard times. We are tailoring the marketing to be very specific to this customer, and it’s the technology that allows this to happen in near real-time. Conclusion As we enable more right-time integrations and interactions, retailers will begin to offer increased service to their customers. Localized and personalized service at scale will drive loyalty and lead to meaningful revenue growth for the retailers that execute well. Our industry needs to support Commerce Anywhere…and commerce anytime as well.

  • Can defect containment metrics be readily applied at an organizational level when there is only a consistant organizational process framework?

    - by Thomas Owens
    Defect containment metrics, such as total defect containment effectiveness (TDCE) and phase containment effectiveness (PCE), can be used to give a good indicator of the quality of the process. TDCE captures the defects that are captured at some point between requirements and the release of a product into the field, indicating the overall effectiveness of the entire process to find and remove defects. PCE provides more detail at each phase of the software development life cycle and how the defect detection and removal techniques are working. Applying these metrics makes sense at a level where you have a well-defined process and methodology for product development, often a project. However, some organizations provide a process framework that is tailored at the project level. This process framework would include the necessary guidance for meeting certifications (ISO9001, CMMI), practices for incorporating known good techniques (agile methods, Lean, Six Sigma), and requirements for legal or regulatory reasons. However, the specific details of how to gather requirements, design the system, produce the software, conduct test, and release are left to the product development teams. Is there any effective way to apply defect containment metrics at an organizational level when only a process framework exists at the organizational level? If not, what might be some ideas for metrics that can be distilled from each project (each using a tailored process that fits into the organizational process framework) that captures defect containment metrics to discuss the ability of the process to find and remove defects? The end goal of such a metric would be to consolidate the defect containment practices of a large number of ongoing projects and report to management. The target audience would be people in roles such as the chief software engineer and the chief engineer (of all engineering disciplines) for the organization. Although project specific data would be available, the idea is to produce something that quantifies the general effectiveness of all tailored processes across all ongoing projects. I would suspect that this data would also be presented as part of CMMI, ISO, or similar audits to demonstrate process quality.

  • JDeveloper Users - We Want to Hear Your Opinion

    - by Shay Shmeltzer
    One of our goals as product managers is to make sure that customers are happy with the product we deliver. We only get to interact with a small number of developers in a face-to-face way and get feedback and there are a lot of other developers who we don't get a chance to meet. To try and get more complete input, we created an online survey that will help us learn about usage patterns and the level of satisfaction JDeveloper users have with various features and aspects of their work with the tool.  It would be great if you could take 5 minutes and complete this online survey here. The survey is aimed at anyone using JDeveloper, whether for ADF development or any other type of development and for any version.  Hopefully this survey will help us deliver a product that better answers your needs and will help us make your JDeveloper usage experience better. Note - this is a new survey which is unrelated to the previous one that was focused on learning needs. Once you are done with this survey and if you would like to provide more feedback, note that we are also looking specifically for Java developers who are using Mac, as well as developers who are interested in building extensions to JDeveloper.

  • SQL SERVER – Difference between DATABASEPROPERTY and DATABASEPROPERTYEX

    - by pinaldave
    Earlier I asked a simple question on Facebook regarding difference between DATABASEPROPERTY and DATABASEPROPERTYEX in SQL Server. You can view the original conversation there over here. The conversion immediately became very interesting and lots of healthy discussion happened on facebook page. The best part of having conversation on facebook page is the comfort it provides and leaner commenting interface. Question Question from SQLAuthority.com: What is the difference between DATABASEPROPERTY and DATABASEPROPERTYEX in SQL Server? Answer Answer from Rakesh Kumar: DATABASEPROPERTY is supported for backward compatibility but does not provide information about the properties added in this release. Also, many properties supported by DATABASEPROPERTY have been replaced by new properties in DATABASEPROPERTYEX.- source (MSDN). Answer from Alphonso Jones: The only real difference I can see is one, the number of properties contained and the other is that EX returns a sql_variant while DATABASEPROPERTY returns only int. Answer from Ambati Venkatasiva: Both are system meta data functions. DATABASEPROPERTYEX Returns the current setting of the specified database option. DATABASEPROPERTYEX returns the sq-varient value and DATABASEPROPERTY returns integer value. Answer from Rama Sankar Molleti:  Here is the best example about databasepropertyex SELECT DATABASEPROPERTYEX('dbname', 'Collation') Result SQL_1xCompat_CP850_CI_AS Whereas with databaseproperty it retuns nothing as the return type for this is integer. Sql_variant datatype stores values of various sql server supported datatypes except text, ntext, image and timestamp. Answer from Alok Seth:  SELECT DATABASEPROPERTYEX('AdventureWorks', 'Status') DatabaseStatus_DATABASEPROPERTYEX GO --Result - ONLINE SELECT DATABASEPROPERTY('AdventureWorks', 'Status') DatabaseStatus_DATABASEPROPERTY GO --Result - NULL Summary Use DATABASEPROPERTYEX as it is the only function supported in future version as well it returns status of various database properties which does not exists with DATABASEPROPERTY.

  • Design pattern for procedural terrain assets

    - by Alex
    I'm developing a procedural terrain class at the moment and am stuck on the correct design pattern. The terrain is 2D and is constructed from a series of (x,y) points. I currently have a method that just randomly adds points to an array of points to generate a random spread of points. However I need a more elaborate system for generating the terrain. The terrain will be built form a series of re-accuring terrain structures eg. a pit, jump, hill etc. Each structure will have some randomness assigned to it, each height of hill will be random, pit size will be random etc. Each terrain structure will have: A property detailing the number of points making up that structure A method for generating the points (not absolutely necessary) My current thinking is to have a class for each terrain structure, create a fixed amount of terrain elements ahead of the player, loop over these and add the corresponding points to the game. What is the best way to create these procedural terrain structures when they are ultimately just a set of functions for generating terrain elements? Is a class for each terrain element excessive? I'm developing the game for iphone so any objective-c related answers would be welcome.

  • when to introduce an application services tier in an n-tier application

    - by user20358
    I am developing a web based application whose primary objective is to fetch data from the database, display it on the UI, take in user inputs and write them back to the database. The application is not going to be doing any industrial strength algorithm crunching, but will be receiving a very high number of hits at peak times (described below) which will be changing thru the day. The layers are your typical Presentation, Business, Data. The data layer is taken care of by the database server. The business layer will contain the DAL component to access the database server over tcp. The choices I have to separate these layers into tiers are: The presentation and business layers can be either kept on the same tier. The presentation layer on a separate tier by itself and the business layer on a separate tier by itself. In the case of choice 2, the business layer will be accessed by the presentation layer using a WCF service either over http or tcp. I don't see any heavy processing being done on the Business layer, so I am leaning towards option 1 above. I also feel for the same reason, adding a new tier will only introduce the network latency. However, in terms of scalability in case I need to scale up or scale out, which is a better way to go? This application will need to be able to support up to 6 million users an hour. There will be a reasonable amount of data in each user session, storing user's preferences and other details. I will be using page level caching as well.

  • How to back up server with rsync, preserving ownership/permissions without root login

    - by olilarkin
    I am setting up a backup server on which I want to run rsync over ssh to backup content on other servers every night. I would like to set up ssh keys to make it password-less, but I want to preserve ownership of files and permissions. There are a number of users on the server to be backed up which won't all exist on the backup server. What would be the best way to do this? I guess the backup job will need to connect as root to , but I don't want to enable root ssh access on the servers. thanks for any tips, oli ps, all servers are running UBUNTU Server 12.04 LTS and are behind a university firewall.

  • Finding out whether files are added, changed or deleted on a FTP server

    - by futureelite7
    I've recently been given the task to migrate about 200GB of data from one dedicated server to another. As this will take a week or more, I've been taking a snapshot of the current files on the FTP server using wget's mirror feature. However, since other users will probably be uploading / changing stuff in the meantime, the snapshot that I have made will not include the most recent changes. Since I only have access to FTP on this server, I'm planning to write a script that will recursively do a FTP stat on all files in the FTP folder, and compare the directory listing against the snapshot I have locally. If there are differences in the number of files, then I know files have been added or deleted. If the modification dates have been changed, then I know the files have been changed, and should redownload those files specifically. Am I missing anything in my approach, or are there any possible improvements to this approach?

  • Windows 7 loses access to network drives

    - by dubRun
    Ok this is an odd one, but is happening often enough its getting quite annoying. I recently installed Windows 7 on my work computer (about 2 months ago) and every so often I lose access to network shares on our work network. Its one server in particular - other shares are still working fine. I have a number of folders mapped as a drive, and all of the ones on a particular file server have lost access. If I try to access the machine directly (\fileserver\d$) it doesn't work either with this message: Windows cannot access \fileserver\d$. You do not have permission to access \fileserver\d$. Contact your network administrator to request access Once I reboot the computer, access is restored like it should be. The computers are all on a domain and my user has administrator level access to the server in question.

  • Should I consolidate multiple identical VMs into BSD jails?

    - by Josh
    We run a number of Openfire XMPP/Jabber servers. Due to the way Openfire works, we cannot easily run multiple Openfire instances on one server, so I have 5 identical VMware ESXi VMs, each with CentOS, MySQl, Java, and Openfire. They're the exact same, except for their IP addresses, the actual Openfire MySQL database and it's config file. I am wondering if this is the optimal configuration, or if it would be better to move these VMs to a single FreeBSD machine and put each one inside a FreeBSD jail. Specifically, I am wondering if the benefit of VMWare's Transparent Page Sharing (TPS) would outweight the cost of running 5 identical OSes. Would I end up using less memory with one large FreeBSD machine and java running in bsd jails?

  • Project Euler 14: (Iron)Python

    - by Ben Griswold
    In my attempt to learn (Iron)Python out in the open, here’s my solution for Project Euler Problem 14.  As always, any feedback is welcome. # Euler 14 # http://projecteuler.net/index.php?section=problems&id=14 # The following iterative sequence is defined for the set # of positive integers: # n -> n/2 (n is even) # n -> 3n + 1 (n is odd) # Using the rule above and starting with 13, we generate # the following sequence: # 13 40 20 10 5 16 8 4 2 1 # It can be seen that this sequence (starting at 13 and # finishing at 1) contains 10 terms. Although it has not # been proved yet (Collatz Problem), it is thought that all # starting numbers finish at 1. Which starting number, # under one million, produces the longest chain? # NOTE: Once the chain starts the terms are allowed to go # above one million. import time start = time.time() def collatz_length(n): # 0 and 1 return self as length if n <= 1: return n length = 1 while (n != 1): if (n % 2 == 0): n /= 2 else: n = 3*n + 1 length += 1 return length starting_number, longest_chain = 1, 0 for x in xrange(1, 1000001): l = collatz_length(x) if l > longest_chain: starting_number, longest_chain = x, l print starting_number print longest_chain # Slow 31 seconds print "Elapsed Time:", (time.time() - start) * 1000, "millisecs" a=raw_input('Press return to continue')

  • How do I implement the bg, &, and bg commands functionaliity in my custom unix shell program written in C

    - by user1631009
    I am trying to extend the functionality of my custom unix shell which I earlier wrote as part of my lab assignment. It currently supports all commands through execvp calls, in-built commands like pwd, cd, history, echo and export, and also redirection and pipes. Now I wanted to add the support for running a command in background e.g. $ls -la& Now I also want to implement bg and fg job control commands. I know this can be achieved if I execute the command by forking a new child process and not waiting for it in the parent process. But how do I again bring this command to foreground using fg? I have the idea of entering each background command in a list assigning each of them a serial number. But I don't know how do I make the processes execute in the background, then bring them back to foreground. I guess wait() and waitpid() system calls would come handy but I am not that comfortable with them. I tried reading the man pages but still am in the dark. Can someone please explain in a layman's language how to achieve this in UNIX system programming? And does it have something to do with SIGCONT and SIGSTP signals?

  • Postgres error messages in Apache error log

    - by Warren Pena
    I'm running Apache 2.2, PHP 5.2, and Postgres 8.2 on Windows, and I'm seeing something funky in Apache's error.log file. Occasionally, I'll see the message "row number -1 is out of range 0..-1" pop up over and over. Unlike all the other lines in that log file, there's no timestamp or log level. Just that exact string. Googling around, it appears that message is, character for character, a common Postgres error message, but is not an Apache error. I've seen it happen multiple times, and on several different servers. I can't seem to reproduce it, though. I've tried throwing all sorts of error ridden database queries and result set inquiries at Postgres via PHP, and none of them seem to trigger that line being written to the log file. Is it possible for Postgres errors to be ending up in my Apache log file, and if so, how? What would trigger an error message like that? Thanks!
