  • Which is more maintainable -- boolean assignment via if/else or boolean expression?

    - by Bret Walker
    Which would be considered more maintainable? if (a == b) c = true; else c = false; or c = (a == b); I've tried looking in Code Complete, but can't find an answer. I think the first is more readable (you can literally read it out loud), which I also think makes it more maintainable. The second one certainly makes more sense and reduces code, but I'm not sure it's as maintainable for C# developers (I'd expect to see this idiom more in, for example, Python).

  • How ReSharper saved the day

    - by Randy Walker
    The Back Story: As a Microsoft MVP awardee, one of the many benefits is free software, books, and various products.  Some of the producers/manufacturers ask for reviews in exchange, others just ask for a brief mention (nothing is ever really free).  But considering that some of the products are essential to my everyday computing, I never mind mentioning their names and evangelizing their products. One of these tools just happened to save me a countless number of hours.  With the release of Microsoft’s Visual Studio 2010, JetBrains released their new 5.0 version of ReSharper. The Story: My specialty is Visual Basic development.  I am not, and probably will never be a C# developer.  As such, trying to figure out how to debug a C# project, that was written 2 years ago by a contract developer, let’s just say it’s a painful process. I have a special class for config file reading and writing, written in C#.  I kept getting exceptions when the reader would get to a line that had an xml comment in it.  It took me a couple of hours to narrow down where it was happening and why, but I couldn’t figure out the best way to fix it.  It was a for loop that was implicitly casting the type of the variable.  I knew I need to explicitly cast the variable type, but only after the type was verified.  So after I finally got some of the code written, ReSharper gave me some suggestions on how to write the code better. One of the ways was to safely cast the variable into the type I wanted.  Blammo, no more exceptions in a way I hadn’t anticipated.  Instead of having to check the type before I cast it.  Beautiful, simple, and taught me a better way to code C#. Kudos JetBrains … now if it only worked better with VB (then it could be called ReBasic, ReVB, RE???)

  • Returning Value of Radio Button Jquery [migrated]

    - by Jerry Walker
    I am trying to figure out why, when I run this code, I am getting undefined for my correct answers. $(document).ready (function () { // var answers = [["Fee","Fi","Fo"], ["La","Dee","Da"]], questions = ["Fee-ing?", "La-ing?"], corAns = ["Fee", "La"]; var counter = 0; var $facts = $('#main_ .facts_div'), $question = $facts.find('.question'), $ul = $facts.find('ul'), $btn = $('.myBtn'); $btn.on('click', function() { if (counter < questions.length) { $question.text(questions[counter]); var ansstring = $.map(answers[counter], function(value) { return '<li><input type="radio" name="ans" value="0"/>' + value + '</li>'}).join(''); $ul.html(ansstring); var currentAnswers = $('input[name="ans"]:checked').map(function() { return this.val(); }).get(); var correct = 0; if (currentAnswers[counter]==corAns[counter]) { correct++; } } else { $facts.text('You are done with the quiz ' + correct); $(this).hide(); } counter++; }); // }); It is quite long and I'm sorry about that, but I don't really know how tostrip it down. I also realize this isn't the most elegant way to do this, but I just want to know why I can't seem to get my radio values. I will add the markup as well if anyone wants.

  • Mobile Apps: An Ongoing Revolution

    - by Steve Walker
    a guest post from Suhas Uliyar, VP Mobile Strategy, Product Management, Oracle The rise of smartphone apps have proved transformational for businesses, increasing the productivity of employees while simultaneously creating some seriously cool end user experiences. But this is a revolution that is only just beginning. Over the next few years, apps will change everything about the way enterprises work as well as overhauling the experiences of customers. The spark for this revolution is simplicity. Simplicity has already proved important for the front-end of apps, which are now often as compelling and intuitive as consumer apps. Businesses will encourage this trend, both to further increase employee productivity and to attract ‘digital natives’ (as employees and customers). With the variety of front-end development tools available already, this should be a simple mission for developers to accomplish – but front-end simplicity alone is not enough for the enterprise mobile revolution. Without the right content even the most user-friendly app is useless. Yet when it comes to integrating apps with ‘back-end’ systems to enable this content, developers often face a complex, costly and time-consuming task. Then there is security: how can developers strike a balance between complying with enterprise security policies and keeping the user experience simple? Complexity has acted as a brake on innovation, with integration and security compliance swallowing enterprise resources. This is why the simplification of integration, security and scalability is so important: it frees time and money for revolutionary innovation. The key is to put in place a complete and unified SOA integration platform that runs across the entire enterprise and enables organizations to easily integrate and connect applications across IT environments. The platform must also be capable of abstracting apps from the underlying OS and enabling a ‘write-once, run- anywhere’ capability for mobile devices - essential for BYOD environments and integrating third-party apps. Mobile Back-end-as-a-Service can also be very important in streamlining back-end integration. Mobile services offered through the cloud can simplify mobile application development with a standard approach to dealing with complex server-side programming and integration issues. This allows the business to innovate at its own pace while providing developers with a choice of tools to speed development and integration. Finally, there is security, which must be done in a way that encourages users to make the most of their mobile devices and applications. As mobile users, we want convenience and that is why we generally approve of businesses that adopt BYOD policies. Enterprises can safely encourage BYOD as they can separate, protect, and wipe corporate applications by installing a secure ‘container’ around corporate applications on any mobile device. BYOD management also means users’ personal applications and data can be kept separate from the enterprise information – giving them the confidence they need to embrace the use of their devices for corporate apps. Enterprises that place mobility at the heart of what they do will fundamentally transform their businesses and leap ahead of the competition. As businesses take to mobile platforms that simplify integration, security and scalability we will see a blossoming of innovation that will drive new levels of user convenience and create new ways of working that we are only beginning to imagine.

  • How to check that I have recovered from Penguin 2.0?

    - by Simon Walker
    I have 3 year old website which has been hit by Penguin 2.0 in May. The website traffic dropped almost 30%. I have been working hard from last 2.5 months on the website and my website's traffic recovered in last week of August. In fact, I am receiving more traffic then ever. When I look at the stats, I find my website's search engine visibility has been improved. It is now appearing for more search queries. My website's impressions have also increased. What I am worried about is that my website is nowhere in top 5 pages for keywords having high competition and carrying the highest search volume. They are few in number but important. Should I consider my current situation as recovery or it's just the partial recovery? If it is only partial, then how come traffic is more then it was before penguin 2.0?

  • Amazon Affiliate search using a movie title

    - by Matt Walker
    I am currently working on a movie trailer site. I have over 300 movies and I do not want to add an amazon affiliate link to each one individually. Does amazon offer any sort of api that will allow me to use a movie title to search for a dvd on amazon? Ex. For the movie skyfall, the amazon affiliate link would be amazon.com/search/dvd/skyfall/affiliateid ^ I just made the link up as i don't know how their system works, but I just want it to do a search on the movie title Thanks in advance for any help you can give me!

  • How to Prevent Site For Penality [on hold]

    - by Simon Walker
    I have been working hard to recover site from Penguin 2.0 and I was successful in it. A week before Penguin 2.1 one of my competitor created thousands of spam backlinks in just 2 days. The timing is more than perfect to make my website victim of Penguin 2.1. I have disavowed all those dirty links and regularly updating the disavow sheet for poor backlinks. Is there else I can do with the site to recover faster. http://bit.ly/fvbyLg

  • Retail Link data storage requirements

    - by Randy Walker
    I was asked today about how much data an average Retail Link analyst (Walmart vendor) would consume.  I thought I would write this small post for future reference. Of course this vastly depends on the amount of skus, how long you want to archive data, and if you want store level sales. Most reports take up very little space. Most times when you download a report (total sales per sku for last week), you will overwrite the previous week’s report.  However, most users will take the data inside their downloaded report, and add it to a database or larger excel spreadsheet.  This way, the user has a history of the sales of each item/sku per week over the last 2+ years.  I would estimate 1 user to consume around 1-2 gb of space, at most, over the course of 2 years. If you start archiving store level sales those numbers can drastically increase up to 10gb or more very quickly.

  • Inexpensive Business Checks

    - by Randy Walker
    One of the most annoying things when setting up a business is paying the outrageous fees for business checks.  When starting out, rather than pay the $150 for the handful of computer printable checks, I had bought software that would create the checks for me.  But if you didn’t know, those little digits at the bottom of a check are magnetically encoded and requires special ink. Fortunately, my current bank has one of the best bill pay websites, so I have exclusively used it.  But since I recently had to open a new bank account, I went off in search of a cheap alternative for business checks.  A bit wary of some of the printers, I opted for TechChecks and was extremely surprised a few days later when my checks arrived in perfect condition.  (I recommend the diamond prismatic red-blue-green checks.  Beautiful and very professional looking.) It was perfect timing as well, since I now have to reorder some checks for another account.

  • 12.04 - why does the network icon dissapear every time my machine is turned off

    - by Howard Walker
    After spending an hour or two working out how to find the network Icon, I find that when I reboot the machine, I have to go through the whole procedure again. 1. The network menu is not there - so first I have to find the terminal. This has no particular location that I can find but usually I have to type terminal in the dash. 2. Then I have to type nm-applet in terminal 3. The network manager icon then appears, but only works if the terminal window remains open. Shut down the terminal window and the network disappears. This is a pain - plus I have to type my password in every time, which is another waste of time, thought this has always been a problem. So can anyone tell me how to make the web automatically connect at startup without any intervention from me.

  • Design: How to model / where to store relational data between classes

    - by Walker
    I'm trying to figure out the best design here, and I can see multiple approaches, but none that seems "right." There are three relevant classes here: Base, TradingPost, and Resource. Each Base has a TradingPost which can offer various Resources depending on the Base's tech level. Where is the right place to store the minimum tech level a base must possess to offer any given resource? A database seems like overkill. Putting it in each subclass of Resource seems wrong--that's not an intrinsic property of the Resource. Do I have a mediating class, and if so, how does it work? It's important that I not be duplicating code; that I have one place where I set the required tech level for a given item. Essentially, where does this data belong? P.S. Feel free to change the title; I struggled to come up with one that fits.

  • Storing data offline with javascript

    - by Walker
    My question is about storing data offline and potentially whether I will need to bring in an outside programmer or could this be learned within a few weeks? The website I am working on will have an interface where users will login and go through a series of quizzes in the form of checkbox, drop down menus, and others. Each page/quiz area could have 20-100 total checkboxes in a series of 3-5 rows because of the comprehensive nature of course. This I can do - I know how to code the quiz and return a correct or incorrect answer based on each individual checkbox and present a cumulative score (ie: you got 57% correct). The issue lies in the fact that I would like to save the users results and keep them informed of their progress. When they complete all of the quizzes, I would like to have a visual output of their performance in each area. Storing the output from their results offline is where I think I may run into a problem with my lack of coding experience. I would also like to have a sidebar with their progress of each section (10-15) with a green percentage completion bar or a % correct which would draw from this. I have never had to code something that stores information like this offline - so back to my question - would it be better to learn the language needed or bring in a coder/developer for the back end stuff.

  • Googlebot requesting invalid url

    - by Rob Walker
    I have a web app which emails me exceptions automatically. This morning there was an error relating to a url: /Catalog/LiveCatalog?id=ylwpfqzts id is invalid (should be a guid) and caused an error parsing. Everything was handled correctly, and an error page is returned. But what was odd is that the user-agent reported itself as Googlebot and the IP is registered to Google. The URL would never have been generated by my web app but doesn't look particularly malicious. Anyone ever seen anything like this?

  • Website Registration Date

    - by Matt Walker
    I recently registered a website : cinematrailers.net. I was aware that this domain was expired ( registered in 2007 until 2011) My question is when I go to view the registration date on this domain, it says 2012 instead of 2007. Why is that when it was clearly registered in 2007? And will this affect seo? I was under the assumption that the domains age would be great for seo, but now I'm not sure.

  • Korea&rsquo;s Anti Abortion / Pro Life Movement

    - by Randy Walker
    The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

  • Apache2 Enabling Includes module causes svn access to quit working

    - by Matthew Talbert
    I have dav_svn installed to provide http access to my svn repos. The url is directly under root, eg mywebsite.com/svn/individual-repo. This setup has been working great for some time. Now, I need SSI (server-side includes) for a project, so I enabled this module with a2enmod include. Now, tortoisesvn can't access the repo; it always returns a 301 permanent redirect. Some playing with it reveals I can access it in a browser if I'm sure to include the trailing / but it still doesn't work in TortoiseSVN. I've looked at all of the faq's for this problem with TortoiseSVN and apache, and none of them seem to apply to my problem. Anyone have any insight into this problem? I'm running Ubuntu 9.10 with Apache 2.2.12. The only change I've made to my configuration is to enable the includes mod. Here's my dav_svn conf: <Location /svn> DAV svn SVNParentPath /home/matthew/svn AuthType Basic AuthName "Subversion repository" AuthUserFile /etc/subversion/passwd Require valid-user </Location> and here's the relevant part of my virtual host conf: <Location /svn> SetHandler None Order allow,deny Allow from all </Location> Edit: OK, I've discovered that the real conflict is between the include module and basic authentication. That is, if I disable the include module, browse to the subversion repo, enter my user/pass for the basic authentication, I can browse it just fine. It even continues to work after I re-enable the include module. However, if I browse with another browser where I'm not already authenticated, then it no longer works.

  • Crazy problem with Nginx, PHP5-FPM on Ubuntu

    - by Emmanuel
    I've been trying to get a domain from shared hosting to my new VPS. Everything was working just 100% fine, and then all of a sudden rewrites stopped working, pictures that should work started returning 404s. I've got no idea why, but for some reason on my site: http://www.onlythebible.com/ only the home page works, all the other pages depend on rewrites which were working perfectly fine at one stage, but all of a sudden stopped working. Some of the pictures like this url: http://www.onlythebible.com/bgsPreview/Matthew-8.10.jpg which doesn't use a rewrite throws a 404? I almost certain it was nothing to do with the nginx configuration. I've got suspicions that it could be something to do with php5-fpm? The funny thing is, all of a sudden it started working again. And then an hour or so later it broke again and has now gone back to only displaying the home-page and all of the links (and some of the pictures) are just showing 404s. Does anyone have an idea of what the problem might be? I'm pretty new to the whole Linux VPS thing, but this just seems very strange. *edit Here's a line from the error log which might shed some light on the problem: 2011/02/06 03:04:59 [error] 2873#0: *220 open() "/usr/local/nginx/html/bgsPreview/Matthew-8.10.jpg" failed (2: No such file or directory), client: 114.77.115.211, server: onlythebible.com, request: "GET /bgsPreview/Matthew-8.10.jpg HTTP/1.1", host: "www.onlythebible.com", referrer: "http://www.onlythebible.com/" I wonder why it's trying to find the file in /usr/local/nginx/html instead of the proper root which is /var/www/ etc... Oh, and for some reason it's just started working again... for how long I don't know. Another thing that was a bit weird, is that the pages on my website are pulled from a database. But when I edited the database, the pages didn't change... It's almost like they've been cached or something.

  • Can Castle Monorail and ASP.NET MVC coexist in the same project?

    - by Matthew
    I have a large Monorail project that we have decided we are going to move over to ASP.NET MVC. Most of the underlying system will likely be reusable, but the Controllers will of course have to be rewritten, and proabably at least some of the views. It strikes me that a low risk avenue for this is gradually convert well defined sections of the system to MVC, and perhaps as MVCContrib Portable Areas. Does anyone know if there are any non-obvious gotchas that I am likely to run into with this approach? Thanks for your input, Matthew

  • Problem with From field in contact form and mail() function

    - by Matthew
    I've got a contact form with 3 fields and a textarea... I use jQuery to validate it and then php to send emails. This contact form works fine but, when I receive an email, From field isn't correct. I'd like to want that From field shows text typed in the Name field of the contact form. Now I get a From field like this: <[email protected]> For example, if an user types "Matthew" in the name field, I'd like to want that this word "Matthew" appears in the From field.
