  • Use Those Schemas, People!

    - by BuckWoody
    Database Schemas are just containers – they aren’t users or anything else – think of a sub-directory on the hard drive. In early versions of SQL Server we “hid” schemas, placing all objects under “dbo”, which gave the erroneous perception that Schemas are users. In SQL Server 2005, we “un-hid” or re-introduced schemas within the database. Users can have a default schema (a place where their new objects go), you can add new schemas and transfer objects between them, and they have many other benefits. But I still see a lot of applications, developed by shops I know as well as vendors, that don’t make use of a Schema. Everything is piled under dbo. I completely understand this – since permissions can be granted to a schema, they feel a lot like a user, so it’s just easier not to worry about both users and schemas when you create a database. But if you’ll use them properly you can make your application more understandable and portable. You should at least take a few minutes and read more about them – you owe it to your users: http://msdn.microsoft.com/en-us/library/ms190387.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Zune API Library for Ruby

    - by kerry
    Those of you who know me, know my favorite music player is the Zune. For some reason it seems most of my spare time lately seems to be creating Zune API libraries for different languages (I have a PHP one as well).  Here’s another one for Ruby!  If you use it, let me know.  I would love to hear what people are working on. It’s hosted at github, and very easy to use. zune_card = Zune::ZuneCard.for('a_zune_tag') Checkout the README for deets on what fields the object will have.

  • Google webmaster Verification failed.

    - by KMC
    I have a site created by Ruby on Rails. I had verified against Google Webmaster Tool some months ago, which was successful. One day webmaster starts giving me Re-verification fails. I tried again to verify my site using Meta tags and HTML files. But I kept having "Verification failed. The connection to your server timed out." Since then, Google stop crawling my site's content - though, somehow google still crawl my PDF contents on my site.

  • Infrastructure to effectively set up experiements and learn from them

    - by David
    Open-org.com is in the early stages of creating our first product, a place on the web, where one can ask lawyers questions at a fraction of their normal costs. An early stage front page can be found here. I got inspired by this video, which is recommended by Jeff Atwood, which talks about getting feedback faster, which is the reason for this question. The problem Needless to say, we want our conversion rates to be as high as possible. Therefore, we want to be able to rapidly set up a new experiment where we change something on the site (like moving an image slightly, rewriting a sentence etc.). We then want to present the modified page to a random subset of the users. After that we will compare the conversion rates of the experiment with another version. I could very well imagine that we want to run 10-100 experiments simultaneously and it would be nice to have features, where experiments that obviously have worse results will be ended before schedule. My question Does infrastructure to support the whole process exist? A short description of our infrastructure... We use EC2 and PHP and have a script to automatically start up new instances with all needed software. Still, starting up a new server for every experiment, seems like a bit of overkill, so I am wondering what other options exist. Btw. If you feel like working for Open-org.com, you can pick a task, and start working, or suggest a new task. All profits are given out to the contributors.

  • Is there an equivalent to the Max OS X software Hazel that runs on Ubuntu?

    - by Stuart Woodward
    Is there an equivalent to the Max OS X software Hazel that runs on Ubuntu? "Hazel watches whatever folders you tell it to, automatically organizing your files according to the rules you create. It features a rule interface [..]. Have Hazel move files around based on name, date, type, what site/email address it came from [..] and much more. Automatically put your music in your Music folder, movies in Movies. Keep your downloads off the desktop and put them where they are supposed to be." This question probably won't make sense unless you have used Hazel, but basically you can define rules via the GUI to move and rename files automatically to make an automated workflow.

  • Why does F. Wagner consider "NOT (AI_LARGER_THAN_8.1)" to be ambiguous?

    - by oosterwal
    In his article on Virtual Environments (a part of his VFSM specification method) Ferdinand Wagner describes some new ways of thinking about Boolean Algebra as a software design tool. On page 4 of this PDF article, when describing operators in his system he says this: Control statements need Boolean values. Hence, the names must be used to produce Boolean results. To achieve this we want to combine them together using Boolean operators. There is nothing wrong with usage of AND and OR operators with their Boolean meaning. For instance, we may write: DI_ON OR AI_LARGER_THAN_8.1 AND TIMER_OVER to express the control situation: digital input is on or analog input is larger than 8.1 and timer is over. We cannot use the NOT operator, because the result of the Boolean negation makes sense only for true Boolean values. The result of, for instance, NOT (AI_LARGER_THAN_8.1) would be ambiguous. If "AI_LARGER_THAN_8.1" is acceptable, why would he consider "NOT (AI_LARGER_THAN_8.1)" to be ambiguous?

  • De-index URL paremeters

    - by Doug Firr
    Upon reading over this question is lengthy so allow me to provide a one sentence summary: I need to get Google to de-index URLs that have certain parameters appended I have a website example.com with language translations. There used to be many translations but I deleted them all so that only English (Default) and French options remain. When one selects a language option a parameter is aded to the URL. For example, the home page: https://example.com (default) https://example.com/main?l=fr_FR (French) I added a robots.txt to stop Google from crawling any of the language translations: # robots.txt generated at http://www.mcanerin.com User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /*?l= So any pages containing "?l=" should not be crawled. I checked in GWT using the robots testing tool. It works. But under html improvements the previously crawled language translation URLs remain indexed. The internet says to add a 404 to the header of the removed URLs so the Googles knows to de-index it. I checked to see what my CMS would throw up if I visited one of the URLs that should no longer exist. This URL was listed in GWT under duplicate title tags (One of the reasons I want to scrub up my URLS) https://example.com/reports/view/884?l=vi_VN&l=hy_AM This URL should not exist - I removed the language translations. The page loads when it should not! I played around. I typed example.com?whatever123 It seems that parameters always load as long as everything before the question mark is a real URL. So if Google has indexed all these URLS with parameters how do I remove them? I cannot check if a 404 is being generated because the page always loads because it's a parameter that needs to be de-indexed.

  • Analysing Group & Individual Member Performance -RUP

    - by user23871
    I am writing a report which requires the analysis of performance of each individual team member. This is for a software development project developed using the Unified Process (UP). I was just wondering if there are any existing group & individual appraisal metrics used so I don't have to reinvent the wheel... EDIT This is by no means correct but something like: Individual Contribution (IC) = time spent (individual) / time spent (total) = Performance = ? (should use individual contribution (IC) combined with something to gain a measure of overall performance).... Maybe I am talking complete hash and I know generally its really difficult to analyse performance with numbers but any mathematicians out there that can lend a hand or know a somewhat more accurate method of analysing performance than arbitrary marking (e.g. 8 out 10)

  • Seeking a free Lint for C which programmers will *want* to use

    - by Mawg
    When I try to persuade others to Lint their code I always get excuses - too difficult to set up, too difficult to understand, false positives, etc (most of which translates to too lazy, too stupid or too afraid of new things). Is there any way that I can make Linting easier? We code in C using Netbeans. Can I incorporate Splint into Netbeans? I did find a Splint GUI which was quite good, but there was no way to lint a directory tree. Any ideas? Thanks in advance

  • Best tool to understand source

    - by cache
    I have a source code for a project. I am working on porting it to another device as the current source code is for a linux environment. I am having some error on the newly ported code. So i was thinking it would be best to once again understand the whole source code and this will help me localise the errors. Now the problem is that i tried using 'gdb' for linux to debug the code but it does not help. So is there any tool that I can use to trace the program line by line ? By doing so i can understand the program flow. Please Help !

  • Google Fetch issue

    - by Karen
    When I do a Google fetch on any of my webpages the results are all the same (below). I'm not a programmer but I'm pretty sure this is not correct. Out of all the fetches I have done only one was different and the content length was 6x below and showed meta tags etc. Maybe this explains other issues I've been having with the site: a drop in indexed pages. Meta tag analyzer says I have no title tag, meta tags or description even though I do it on all pages. I had an SEO team working on the site and they were stumped by why pages were not getting indexed. So they figure it was some type of code error. Are they right?

  • Share Mulitple Classes as one dll or a lib with Mulitple Projects

    - by JNL
    Currently I have some shared class files(.cpp and .h) which I include them in around 20 Projects. Currently I have to include them in all of the projects. So if I get some business requirments and I change some of the shared(.cpp or .h) files I have to include them in all the 20 Projects which is kind of tedious. Is there a way where I can create a shared dll or library and include it all of my Projects. So if I have to change it, I just have to change it once and then just Add Reference to include that dll or library which contains all the shared(.cpp, .h) files. Any help/recommendations regarding the same, will be highly appreciated. I am using VS2012 for VC++.

  • Build & Install Ruby Gems with Rake

    - by kerry
    Are you using rake to build your gems?  Have you ever wished there were an install task to install it to your machine?  I, for one, have written something like this a few times: 1: desc 'Install the gem' 2: task :install do 3: exec 'gem install pkg/goodies-0.1.gem' 4: end 5:  That is pretty straightforward.  However, this will not work under JRuby on Mac where the command should be ‘jgem’.  So we can enhance it to detect the platform, and host OS: 1: desc 'Install the gem' 2: task :install do 3: executable = RUBY_PLATFORM[/java/] && Config::CONFIG[/darwin/] ? 'jgem' : 'gem' 4: exec "#{executable} install pkg/goodies-0.1.gem" 5: end This is a little better.  I am still not comfortable with the sloppiness of building a shell command and executing it though.  It is possible to do it with strictly Ruby.  I am also going namespace it to integrate better with the GemPackageTask.  Now it will be accessed via ‘rake gem:install’ 1: desc 'Install the gem' 2: namespace 'gem' do 3: task :install do 4: Gem::Installer.new('pkg/goodies-0.1.gem').install 5: end 6: end   I have included this in the goodies gem 0.2, so go ahead and install it!  ‘gem install goodies’

  • Software/Hardware Development?

    - by SwarthyMantooth
    Sincere apologies if this is the wrong place to ask this. I am a computer engineering student and I'm currently on my first co-op of the required 5 I have to take, and I've noticed that all I'm really given is software engineering jobs. I love developing software, but I don't want to lose out on the hardware aspect of computers, as having a hybrid knowledge of the two is why I chose this major in the first place. So I guess my question is: Are there any software engineering jobs that still allow you to handle and interface with hardware on a very low level? Or am I to be forced to choose which focus I love more?

  • Redirecting non existing post to homepage; is that good for SEO?

    - by BlackEagle
    I am checking my website out on Google Webmasters and I am seeing an astonishing 5000 links that could not be found by Google's Crawlers. That's normal, because my website is built in a manner that users can drop their own things, which also lead to 404 pages. Not a problem at all if I can find a workaround of course... So my question is: what if I made a function or a mod rewrite that will check if the link exists (a post for example) and if not, it will redirect it to the home page. Is this good for SEO? Will Google see this as 'link found'? How do I have to look at this problem?

  • TSQL formatting - a sure fire way to start a conversation.

    - by fatherjack
    There are probably as many opinions on ways to format code as there are people writing code and I am not here to say that any one is better than any other. Well, that isn't true. I am here to say that one way is better than another but this isn't a matter of preference or personal taste, this is an example of where sloppy formatting can cause TSQL to weird and whacky things but following some simple methods can make your code more reliable and more robust when . Take these two pieces of code, ready...(read more)

  • How does Google Analytics aggregate the Count of Visits (Frequency & Recency Report)?

    - by Brian Dant
    Here's my simple understanding of Count of Visits: Each person that comes to my site gets one "count" for each visit. They are put into a bucket of people with the same number of total counts -- if you visit twice, you are in the two bucket, if you visit six times, you are in the six bucket. From there, a report (Frequency & Recency) makes a line for each bucket and reaches into the bucket and totals the number of people in that bucket, putting that total in the second column. My Question: Will a two month report automatically put someone into two buckets, and put them on two separate lines in the Count of Visits table? This explaination makes it seem like a two-month long report will put the same person into a bucket twice, one bucket for each month. The two-month report will then show that person's visits on two different lines, instead of aggregating them. Example for Clarification: Bob comes to my site three times in January and seven times in February. I run a report for Jan 1 -- Feb 28. Will Bob be on both the Three Count line and the Seven Count line, or will he be on the Ten Count line?

  • How to set up Google DFP (DoubleClick for Publishers) for a site?

    - by Manoj Kumar
    I have a website and I have an AdSense account as well. I have integrated AdSense and ads are also getting displayed (480 x 60). Somewhere I read that I can manage the ads that are being shown in my website (480 x 60) and filter out the ads on a CPM/CPC basis. NOTE: I don't have any ads to be displayed on other's websites. I just want to show other's ads on my website. Now, can I use Google DFP to manage the ads? I mean is Google DFP useful for me to filter the ads and get me more revenue?

  • Database Maintenance Scripting Done Right

    - by KKline
    I first wrote about useful database maintenance scripts on my SQLBlog account way back in 2008. Hmmm - now that I think about it, I first wrote about my own useful database maintenance scripts in a journal called SQL Server Professional back in the mid-1990's on SQL Server v6.5 or some such. But I digress... Anyway, I pointed out a couple useful sites where you could get some good scripts that would take care of preventative maintenance on your SQL Server, such as index defragmentation, updating...(read more)

  • Is there a modern (eg NoSQL) web analytics solution based on log files?

    - by Martin
    I have been using Awstats for many years to process my log files. But I am missing many possibilities (like cross-domain reports) and I hate being stuck with extra fields I created years ago. Anyway, I am not going to continue to use this script. Is there a modern apache logs analytics solution based on modern storage technologies like NoSQL or at least somehow ready to cope with large datasets efficiently? I am primarily looking for something that generates nice sortable and searchable outputs with the focus on web analytics, before having to write my own frontends. (so graylog2 is not an option) This question is purely about log file based solutions.
