  • Book Review: Professional ASP.Net MVC4

    - by Sam Abraham
    The past few weeks have been particularly busy as I continue to dedicate a bigger portion of my free time to refreshing my memory and enhancing my knowledge of best practices pertaining to technologies we plan on using for a major upcoming project. In this blog post, I will be providing a brief overview of my latest reading “Professional ASP.Net MVC4” by Jon Galloway, Phil Haack, Brad Wilson and K. Scott Allen. This book is a must read for web developers looking to enhance their MVC expertise with best practices and tips shared from recognized industry experts. This book takes the reader on a 16-chapter long journey towards being a better ASP.NET MVC developer with chapter 16 putting all information covered in practical context by dissecting the implementation of Nuget.org, a real-life open-source, ASP.NET MVC project.  All code samples referenced in this book are conveniently accessible via NuGet, a free, open-source Library package manager that installs as a Visual Studio Extension. Chapters 2, 3 and 4 thoroughly cover MVC’s various components: Controllers “C”, Views “V” and Models “M” respectively. Chapter 5 covers additional extension methods (Helpers) provided to speed and ease the use of common HTML elements such as forms, textboxes, grids, to name a few… Chapter 6 tackles built-in validation while providing examples and use cases on implementing custom validation that plugs into the MVC framework. Chapters 7 thru 13 discusses the latest on Membership, Ajax, Routing, NuGet and the ASP.Net Web API. Chapters 12 (Dependency Injection) and 13 (Unit Testing) demonstrate a big competitive advantage of MVC with its ease of test-ability and plug-ability. Chapters 14 and 15 targets the advanced developer showcasing how to extend MVC to customize and replace every piece in the framework.In conclusion, I strongly recommend Professional ASP.NET MVC 4 as an excellent read for both developers already using MVC as well as those getting started with the framework.   Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group.  You can access my reviews of books I recently read: Professional ASP.NET Design Patterns Professional WCF 4.0 Inside Windows Communication Foundation Inside Microsoft SQL Server 2008 series

  • mitigating lost emails when switching provider

    - by sam
    were about to change to gmail from a webmail provided by our hosting provider, i understand changing the mx records and all. But my main worry was if there would be any emails that would fall through the gaps of the two systems during change over. Im not familiar with the ins and outs of how the mx record works, is it like a dns record change, ie. it needs to propagate ? If thats the case would there be a period were its left my current email provider but not switched to the new gmail account ? Thus allowing emails not be delivered or worse lost ?

  • Ubuntu 12.04 shut down freezes

    - by sam
    I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

  • Value of links on negative review pages

    - by Sam Healey
    A general assumption with SEO is more links = higher rankings. What I would like to know is does Google know what those links are referring to. I.e. if somebody gives a product a good review on their personal blog and links the review to another companies website (who are selling the product), would Google take consideration for the review/description link. Essentially would Google know that this link refers to a product. So if somebody is looking to buy a product, Google would know to include this page because the previous link said it sells products rather than just having information on products. Then to take this further, does Google know if a link is positive or negative. For example, If somebody creates a post saying, do not visit example.com, example.com is bad because of blah blah blah. Would Google know that the link is getting bad feedback and therefore would it have a negative affect on rankings, or would Google go oh its just another link and give it better rankings?

  • google webmaster showing 6 pages submitted 0 indexed, yet i can see them all there when i search in google?

    - by sam
    I have a small 'brochure' type site with 6 pages, i can see them all the pages showing up in google when i search for my site. But in webmaster tools under the sitemaps section it says 6 submitted, (the blue bar of the graph), but the indexed pages - the red bar is showing 0 indexed pages, even though they seem to be indexed ? any idea why this is ? I dont really think its that important as the pages are still indexed, but it just seems odd. =================================================== UPDATE 9/3/12 having just looked in google webmaster its showing that there are 11 pages indexed, under the health index status tab.. but under the optimization sitemap tab it shows 6 urls submitted but only 1 indexed ? please see images bellow index status: Sitemap status:

  • Install a Mirror without downloading all the packages in the official repository

    - by Sam
    I first gonna explain the situation : ( The two PCs are running Ubuntu 12.04 ) I have a Laptop which is connected to a wifi connection, and a Desktop which can not be connected to Internet ( the modem is too far from it ), and i want to install some software to the last one. ( the two PCs are connected with an Ethernet cable ) I've already searched for a solution, but all i found was the use of some softwares that should have been already installed on the "Internet-less PC". ( Keryx, APTonCD ... ) What I want to do is to create a mirror in my laptop which contain the packages i have in this one ( situated in /var/cache/apt/archive ) and i don't want to download all the packages from the official repository, I don't need them. Can someone tell me if this is possible ? Thank you.

  • Data recovery on Ubuntu 11.10?! (after crashing with Seagate 320GB)

    - by Sam
    Just installed 11.10 last week and decided to transfer iTunes music (from Windows dual boot) to my Seagate 320GB. I left it in, restarted, clicked Ubuntu at the boot screen, and then it froze after a few lines of code! I think I got to 3.7086 or something before I pressed CTRL+ALT+DEL and the system restarted after another few lines of code. I am completely new to Ubuntu so after Googling, I made a live CD with 10.04, the most stable release I've heard, and I'm typing this from there now. However, when I go to mount my partition, only the Windows Vista partition (308GB) is there! It has all my Windows files but my Ubuntu 11.10 ones are nowhere to be found. I need to restore these pictures I transferred from my camera using Shotwell the other day... any help is appreciated! p.s. 11.10 has never crashed on me in my trial week, so I'm guessing it's the Seagate hard drive's fault. However, now I'm running it on 10.04 and it works fine.

  • How can I stop LibreOffice from randomly crashing?

    - by Sam Mercier
    Libreoffice keeps on crashing randomly. It will do this when I am typing and when I am switching desktops or anything. There is no patter to it. I need some help here. Anyone had this problem or problem similar to it? Anyone have found a fix. Also it seems to happen especially prominently after my screensaver has started. I would say it happens about 97% of the time after that. This is an annoying bug and is keeping my productivity low.

  • check when a page was first seen by google

    - by sam
    Is there a way to see when a page was first published, by checking when it was first cahced by google (obviously its not 100% fool proof because there is a couple of days delay in some cases but it will give you a good idea.) The only other way i could think of checking it published date is if the page / post had a publicly viable time stamp on it, but in the case im looking for it, it dosnt have a publicly visible time stamp.

  • Architecture for a template-building, WYSIWIG application

    - by Sam Selikoff
    I'm building a WYSIWYG designer in Ember.js. The designer will allow users to create campaigns - think MailChimp. To build a campaign, users will choose an existing template. The template will have a defined layout. The user will then be taken to the designer, where he will be able to edit the text and style, and additionally change some layout options. I've been thinking about how best to go about structuring this app, and there are a few hurdles. Specifically, the output of the campaign will be dynamic: eventually, it will be published somewhere, and when the consumers (not my users, but the people clicking on the campaign that my user created) visit the campaign, certain pieces of data will change, depending on the type of consumer viewing the campaign. That means the ultimate output of the designer will be a dynamic site. The data that is dynamic for this site - the end product - will not be manipulated by the user in the designer. However, the data that will be manipulated by the user in the designer are things like copy, styles, layout options, etc. I'll call the first set of variables server-side data, and the second client-side data. It seems, then, that the process will go something like this: I'll need to create templates for this designer that have two dynamic segments. For instance, the server-side data could be Liquid expressions, and the client-side data Handlebars expressions. When the user creates a campaign, I would compile the template on the back end using some dummy data for the server-side variables, and serve up a handlebars template to the Ember app. The user would then edit the template, and the Ember app would save all his edits to the JS variables that were powering the template. This way he'd be able to preview the template. When he saves, he'll send back the selected template, along with all the data and options he's made. When it comes time to publish, the back-end system will have to do two things: compile the template with Handlebars using the campaign data, and then compile the template with Liquid using the server-side data Is my thinking roughly accurate about this, or is there a simpler way?

  • Which of these URL scenarios is best for big link menus? [seo /user friendly urls]

    - by Sam
    Hi folks, a question about urls... me and a good friend of mine are exploring the possibilities of either of the three scenarios for a website where each webpage has a menusystem with about 130 links.: SCENARIO 1 the pages menu system has SHORT non-descriptive hyperlinks as well as a SHORT canonical: <a href:"design">dutch design</a> the pages canonical url points to e.g.: "design" OR SCENARIO 2 the pages menu system has SHORT non-descriptive hyperlinks wwith LONG canonical urls: <a href="design">dutch design</a> the pages canonical url points to: dutch-design-crazy-yes-but-always-honest OR SCENARIO 3 the pages menu system has LONG descriptive hyperlinks with LONG canonical urls: <a href="dutch-design-crazy-yes-but-always-honest">dutch design</a> the pages canonical url points to: dutch-design-crazy-yes-but-always-honest Currently we have scenario 2... should we progress to scenario 3? All three work fine and point via RewriteMod to the same page which is fetched underwater. Now, my question is which of these is better in terms of: userfriendlyness (page loading times, full url visible in url bar or not) seo friendlyness (proper indexing due to the urls containing descriptive relevant tags) other concerns we forgot like possible penalties for so many words in link hrefs?? Thanks very much for your suggestions: much appreciated!

  • is redirecting mydomain.eu & mydomain.net to mydomain.com using .htacess spammy?

    - by sam
    a client has asked my to develop their site, they already own 3 domains, mydomain.eu, .net and .com they want all the traffic from .eu and .net to redirect to .com, ive explained to them that it is not that relevant as people will search for them in search engines rather than typing in the domain, but they still would like me to do it. As far as i know this is fine to do from an Seo point of view but i thought id just double check ..

  • Setting up a shared media drive

    - by Sam Brightman
    I want to have a shared media drive be transparently usable to all users, whilst also sticking to FHS and Ubuntu standards. The former takes priority if necessary. I currently mount it at /media/Stuff but /media is supposed to be for external media, I believe. The main issue is setting permissions so that access to read and write to the drive can be granted to multiple users working within the same directories. InstallingANewHardDrive seems both slightly confused and not what I want. It claims that this sets ownership for the top-level directory (despite the recursion flag): sudo chown -R USERNAME:USERNAME /media/mynewdrive And that this will let multiple users create files and sub-directories but only delete their own: sudo chgrp plugdev /media/mynewdrive sudo chmod g+w /media/mynewdrive sudo chmod +t /media/mynewdrive However, the group writeable bit does not seem to get inherited, which is troublesome for keeping things organised (prevents creation inside sub-folders originally made by another user). The sticky bit is probably also unwanted for the same reason, although currently it seems that one userA (perhaps the owner of the mount-point?) can delete the userB's files, but not vice-versa. This is fine, as long as userB can create files inside the directory of userA. So: What is the correct mount point? Is plugdev the correct group? Most importantly, how to set up permissions to maintain an organised media drive? I do not want to be running cron jobs to set permissions regularly!

  • Lenovo e530 no wireless Ubuntu 13.04

    - by Sam
    For some reason my wireless will not work on my Lenovo e530. I am dual booting ubuntu and windows 8 and my wireless works in windows. I saw online that I should run rfkill. I did that but only bluetooth shows up. There is no difference when I press the wireless fn key either, but it does block bluetooth (as it should). I'm really wanting to get into Ubuntu but this is holding me back. To clarify the wireless device does not show at all after running rfkill.

  • Question aboud Headings For Professionals <H1>... <H9> in SEO & Browsercompatibility Differences

    - by Sam
    We all know the importance ans significance of Headings for Professional Webmasters. These were known for professional developers as <h1>Heading 1</h1> h2 ... h6. As a daring webdeveloper I lately needed more short headings for complex structured document and i thought what the hell and went ahead and used in css h1,h2,h3,h4,h5,h6{ } h7{ } h8{ } h9{ } My experiment turned out to pay back. But only in Firefox, Safari, Chrome etc, not in Internet Explorer 8. Q1. Who(&When) decided that All headings should go upto h6, and not h4 or h7? Q2. Why h7 -h9 work perfect in all major browsers, except IE8? Q3. What is the significance for Bing,Yahoo and Googld in terms of recognition or headings h1 ~ h9? obviously h1 is more important than 2, but do they differentiate between h5 and h6? or not anymore after h3?

  • How to start and maintain an after-work project

    - by Sam
    I work as a full time developer. My workplace, however, is very limiting in the technologies and programming languages I can use. All of the work is done in C++. It is clear that C++ is rapidly losing (or maybe already lost) its leading position. (please don't flame me, I have years and years of C++ experience, and I love this language, I am merely stating a fact). I have a few ideas for java/android projects as well as a project I would like to implement in C#. I see this as a way for me to stay current with the job market's trends and I hope that it will help me find my next job in a more up to date area. So here's the problem, my normal workday is 10-11 hours, after finishing with the kids and house chores I get about 1-2.5 hours before I am too tired to think much less code. at that point I am going to bed frustrated, disappointed with myself for not being able to stick with my plans, and then I wake up the next morning to do it all again. I have a few hours more during the weekends but clearly I would need to do something different if I want to reach any of my goals. Is there any way for me to make better use of the time I have? Did any of you guys have a similar problem, and had succefully resolved it?

  • Project Management Techniques (high level)

    - by Sam J
    Our software dev team is currently using kanban for our development lifecycles, and, from the reasonably short experience of a few months, I think it's going quite well (certainly compared to a few months ago when we didn't really have a methodology). Our team, however, is directed to do work defined by project managers (not software project managers, just general business), and they're using the PMBOK methodology. Question is, how does a traditional methodology like PMBOK, Prince2 etc fit with a lean software development methodology like kanban or scrum? Is it just wasting everyone's time as all the requirements are effectively drawn up to start with (although inevitably changed along the way)?

  • All in a Day's Work: Unblocking Multiple Downloaded Files with a Single Command

    - by Sam Abraham
    Files downloaded using Internet Explorer retain Internet Zone permission level and hence are “Blocked” by default on Windows 7 machines. Honestly, while an added overhead for developers; I really appreciate this feature as it provides a good protection layer for casual web users. My workaround is to simply unblock the downloaded zip file (if download was a zip file) which, in turn, unblocks the files stored within. Today however, I was left with a situation where I had to “Open” and “Copy” the content rather than “Save” a zip file. That of course left me with a few dozen files I have to manually unblock. A few minutes of internet search lead me to the link below which worked like a charm: 1-Download streams.exe from SystInternals - http://technet.microsoft.com/en-us/sysinternals/bb897440.aspx 2-Go to command prompt (cmd.exe) 3-Navigate to where you have streams.exe installed 4-Use command line switches: streams.exe –s –d “<folder path>” This removed the Internet Zone restrictions from all files under “<folder path>” and its subfolders as well. [Deleted :Zone.Identifier:$DATA] References: http://social.technet.microsoft.com/Forums/en-US/itproxpsp/thread/806f0104-1caa-4a66-b504-7a681d1ccb33/

  • Looking for a better Factory pattern (Java)

    - by Sam Goldberg
    After doing a rough sketch of a high level object model, I am doing iterative TDD, and letting the other objects emerge as a refactoring of the code (as it increases in complexity). (That whole approach may be a discussion/argument for another day.) In any case, I am at the point where I am looking to refactor code blocks currently in an if-else blocks into separate objects. This is because there is another another value combination which creates new set of logical sub-branches. To be more specific, this is a trading system feature, where buy orders have different behavior than sell orders. Responses to the orders have a numeric indicator field which describes some event that occurred (e.g. fill, cancel). The combination of this numeric indicator field plus whether it is a buy or sell, require different processing buy the code. Creating a family of objects to separate the code for the unique handling each of the combinations of the 2 fields seems like a good choice at this point. The way I would normally do this, is to create some Factory object which when called with the 2 relevant parameters (indicator, buysell), would return the correct subclass of the object. Some times I do this pattern with a map, which allows to look up a live instance (or constructor to use via reflection), and sometimes I just hard code the cases in the Factory class. So - for some reason this feels like not good design (e.g. one object which knows all the subclasses of an interface or parent object), and a bit clumsy. Is there a better pattern for solving this kind of problem? And if this factory method approach makes sense, can anyone suggest a nicer design?
