• Rspec > testing database views

  - by Sean McCleary

  How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

• C# Type comparison

  - by Sean.C

  This has me pooped, is there any reason the following: public abstract class aExtension { public abstract bool LoadExtension(Constants c); // method required in inherit public abstract string AppliesToModule // property required in inherit { get; } public abstract string ExtensionName // property required in inherit { get; } public abstract string ExtensionDescription // property required in inherit { get; } } public class UK : aExtension { public override bool LoadExtension(Constants c) { return true; } public override string AppliesToModule { get { return "string"; } } public override string ExtensionName { get { return "string"; } } public override string ExtensionDescription { get { return "string"; } } } would return false for the following expressions: bool a = t.IsAssignableFrom(aExtension)); bool b = t.BaseType.IsAssignableFrom(aExtension)); bool c = typeof(aExtension).IsAssignableFrom(t); bool d = typeof(aExtension).IsAssignableFrom(t.BaseType); bool e = typeof(aExtension).IsSubclassOf(t); bool f = typeof(aExtension).IsSubclassOf(t.BaseType); bool g = t.IsSubclassOf(typeof(aExtension)); bool h = t.BaseType.IsSubclassOf(typeof(LBT.AdMeter.aExtension)); bool i = t.BaseType.Equals(typeof(aExtension)); bool j = typeof(aExtension).Equals(t.BaseType); T is the reflected Type from the calss UK. Stange thing is i do the exact same thing just on an external assembly in the same application and it works as expected...

• Firefox all but freezes during large file upload; Ajax progress bar infeasible; IE6 works fine

  - by Sean

  I want to provide a progress bar for my users who upload very large files. I did some reading and implemented what should be a pretty straightforward solution: I have a <form> element that contains an file input element; its target is set to the ID of a hidden iframe. On the server side, there's some Spring magic that attaches an object to the user's session; the progress of the upload can be queried from this object. After submitting the form, I start a repeating Ajax call using setInterval that queries the server for the percent-complete using the aforementioned session object. The call repeats every half-second, skipping the Ajax call if the previous call has not yet completed. I use the data from the call to update the width of an onscreen element. When the server call reports that the upload is complete, I clear the interval timer. I created a 100-megabyte file and uploaded it using my interface. This is using Firefox 3.6.3. What I found is that although the upload takes 20-25 seconds, the progress bar doesn't get updated until the very end. Moreover, the entire browser is basically frozen until the upload completes. I assumed that my method must be flawed, but I tried the same page using IE6, and was utterly amazed when it behaved as I had designed it to--the progress bar got updated every half second, and the whole upload only took about 15 seconds, much faster than Firefox. I don't have many add-ons installed, but I tried disabling Firebug and restarting my browser. This marginally improved the performance--I got perhaps a single additional progress bar update mid-upload--but still far from acceptable. Can anyone tell me what I can do to bring Firefox's performance up to the level of IE6? Ugh, I can't believe I actually typed that. EDIT: I just tried uploading a large file from a Firefox 3.6.3 browser on a different machine than the one that's running my web server, and it worked fine. Huh.

• C# Function Inheritance--Use Child Class Vars with Base Class Function

  - by Sean O'Connor

  Good day, I have a fairly simple question to experienced C# programmers. Basically, I would like to have an abstract base class that contains a function that relies on the values of child classes. I have tried code similar to the following, but the compiler complains that SomeVariable is null when SomeFunction() attempts to use it. Base class: public abstract class BaseClass { protected virtual SomeType SomeVariable; public BaseClass() { this.SomeFunction(); } protected void SomeFunction() { //DO SOMETHING WITH SomeVariable } } A child class: public class ChildClass:BaseClass { protected override SomeType SomeVariable=SomeValue; } Now I would expect that when I do: ChildClass CC=new ChildClass(); A new instance of ChildClass should be made and CC would run its inherited SomeFunction using SomeValue. However, this is not what happens. The compiler complains that SomeVariable is null in BaseClass. Is what I want to do even possible in C#? I have used other managed languages that allow me to do such things, so I certain I am just making a simple mistake here. Any help is greatly appreciated, thank you.

• Faster s3 bucket duplication

  - by Sean McCleary

  I have been trying to find a better command line tool for duplicating buckets than s3cmd. s3cmd can duplicate buckets without having to download and upload each file. The command I normally run to duplicate buckets using s3cmd is: s3cmd cp -r --acl-public s3://bucket1 s3://bucket2 This works, but it is very slow as copies each file via the API one at a time. If s3cmd could run in parallel mode, I'd be very happy. Are there other options available as a command line tools or code that people use to duplicate buckets that are faster than s3cmd?

• Sliding div in jquery

  - by Sean

  I am trying to make a toolbar type section on the top of my site. I just need one div that will be hidden by default, and a button that will be hanging off the bottom of that div. When it is clicked, the div should slide down (with the button still on bottom). And upon clicking, it should slide back up. Here is what I currently have: <div id="account_toolbar" style="background-color:#fff;"> <div id="toolbar_contents" style="display:none;"> This is the account toolbar so far </div> <div id="button" style="background-color: #ff0000;"><%= image_tag "templates/_global/my_account.png", :id => "my_account_btn", :style => "float: right; margin-right: 100px;" %></div> </div> The image tag is using ruby/rails syntax, so pay no attention to that. It will render like any other image tag. Here is the jquery i'm using: $('#my_account_btn').click(function () { $('#toolbar_contents').slideToggle(); }); So, this is actually working for the most part. My problem however is that the spacing where the toolbar content div goes, pushes the account button down. When it slides up or down it temporarily attaches itself to the bottom of the div, then jumps back down once it is finished sliding (leaving a gap between the bottom of the hidden div and the top of the account button). I hope that makes sense. thanks

  This is my very first php code and I can't seem to get it to work. (I'm using Eclipse) <html> <body> <?php echo 'Hello World!'; $txt = "I <3 you!"; $num = 19; ?> </html> </body> When I run it (http://localhost/Assignment3.0/index.php), I get: Not Found The requested URL /Assignment3.0/index.php was not found on this server. Apache/2.2.22 (Ubuntu) Server at localhost Port 80 But when I run this (http://localhost/), I get: It works! This is the default web page for this server. The web server software is running but no content has been added, yet. So what could be the problem? Where's my "Hello World!"? Also, for Stackoverflow formatting, how do I start a new line w/o adding a blank line in between?

• Converting byte[] of binary fixed point to floating point value?

  - by Sean Donohue

  I'm reading some data over a socket. The integral data types are no trouble, the System.BitConverter methods are correctly handling the conversion. (So there are no Endian issues to worry about, I think?) However, BitConverter.ToDouble isn't working for the floating point parts of the data...the source specification is a bit low level for me, but talks about a binary fixed point representation with a positive byte offset in the more significant direction and negative byte offset in the less significant direction. Most of the research I've done has been aimed at C++ or a full fixed-point library handling sines and cosines, which sounds like overkill for this problem. Could someone please help me with a C# function to produce a float from 8 bytes of a byte array with, say, a -3 byte offset?

• Webcast Q&A: Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter

  - by kellsey.ruppel

  Last Thursday we had the third webcast in our WebCenter in Action webcast series, "Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter", where customer Sean Mattson from HDS and Rob Vandenberg from Oracle Partner Lingotek shared how Oracle WebCenter is powering Hitachi Data System’s externally facing website and providing a seamless experience for their customers. In case you missed it, here's a recap of the Q&A.   Sean Mattson, Hitachi Data Systems  Q: Did you run into any issues in the deployment of the platform?A: There were some challenges, we were one of the first enterprise ‘on premise’ installations for Lingotek and our WebCenter platform also has a lot of custom features.  There were a lot of iterations and back and forth working with Lingotek at first.  We both helped each other, learned a lot and in the end managed to resolve all issues and roll out a very compelling solution for HDS. Q: What has been the biggest benefit your end users have seen?A: Being able to manage and govern the content lifecycle globally and centrally and at the same time enabling the field to update, review and publish the incremental content changes without a lot of touchpoints has helped us streamline and simplify the entire publishing process. Q: Was there any resistance internally when implementing the solution? If so, how did you overcome that?A: I wouldn't say resistance as much as skepticism that we could actually deploy an automated and self publishing solution.  Even if a solution is great, adoption of a new process can be a challenge and we are still pursuing our adoption targets.  One of the most important aspects is to include lots of training and support materials and offer as much helpdesk type support as needed to get the field self sufficient and confident in the capabilities of the system.  Rob Vandenberg, Lingotek  Q: Are there any limitations regarding supported languages such as support for French Canadian and Indian languages?A: Lingotek supports all language pairs. Including right to left languages and double byte languages such as Chinese, Japanese and Korean Q: Is the Lingotek solution integrated with the new 11g release of WebCenter Sites? A: Yes! In fact, Lingotek is the first OVI partner for Oracle WebCenter Sites  Q: Can translation memories help to improve the accuracy of machine translation?A: One of the greatest long term strategic benefits of using Lingotek is the accumulation of translation memories, or past human translations. These TMs can be used to "train" statistical machine translation engines to have higher and higher quality. This virtuous cycle is ongoing and will consistently improve both machine and human translations.  Q: We have existing translation memories from previous work with our translation service provider. Can they be easily imported in to the Lingotek solution for re-use? Q: Yes, Lingotek is standards compliant. We support TM import in both the TMX and XLIFF formats. Q: If we use Lingotek as a service to do our professional translation and also use the Lingotek software solution, do we get the translation memories to give us a means of just translating future adds and changes ourselves? A: Yes, all the data is yours, always. Lingotek can provide both the integrated translation software as well as the professional translation services. All the content and translation memories are yours. Q: Can you give us an example of where community translation has proved to be successful?A: The key word here is community. If you have a community that cares about you, your content, and the rest of the community, then community translation can work for you. We've seen effective use cases in Product User Groups content, Support Communities, and other types of User Generated content, like wikis and blogs.   If you missed the webcast, be sure to catch the replay to see a live demonstration of WebCenter in action!   Hitachi Data Systems Improves Global Web Experiences with Oracle WebCenter from Oracle WebCenter

• Standards Matter: The Battle For Interoperability Continues

  - by michael.rowell

  Great Article, although it is a little dated at this point. Information Week Article Standards Matter: The Battle for Interoperability goes on Summary If you're guilty of relegating standards support to a "nice to have" feature rather than a requirement, you're part of the problem. If you want products to interoperate, be prepared to walk away if a vendor can't prove compliance. Don't be brushed off with promises of standards support "on the road map." The alternative is vendor lock-in and higher costs, including the cost of maintaining systems that don't work together. Standards bodies are imperfect and must do better. The alternative: splintered networks and broken promises. The point: "The secret sauce to a successful 'working standard' isn't necessarily IETF or another longstanding body," says Jonathan Feldman, director of IT services for the city of Asheville, N.C., and an InformationWeek Analytics contributor. "Rather, an earnest and honest effort by a group that has governance outside of a single corporation's control is what's important." In order to have true interoperability vendors as well as customers must be actively engaged in the standards process. Vendors must be willing to truly work together and not be protecting an existing product. Customers must also be willing to truly to work together and not be demanding a solution that only meets their needs but instead meets the needs of all participants. Ultimately, customers must be willing to reward vendor compliance by requiring compliance in products and services that they purchase and deploy. Managers that deploy systems without compliance to standards are only hurting themselves. Standards do matter. When developed openly and deployed compliantly standards deliver interoperability which provides solid business value.

• Windows 7 Phone Database Rapid Repository – V2.0 Beta Released

  - by SeanMcAlinden

  Hi All, A V2.0 beta has been released for the Windows 7 Phone database Rapid Repository, this can be downloaded at the following: http://rapidrepository.codeplex.com/ Along with the new View feature which greatly enhances querying and performance, various bugs have been fixed including a more serious bug with the caching that caused the GetAll() method to sometimes return inconsistent results (I’m a little bit embarrased by this bug). If you are currently using V1.0 in development, I would recommend swapping in the beta immediately. A full release will be available very shortly, I just need a few more days of testing and some input from other users/testers.   *Breaking Changes* The only real change is the RapidContext has moved under the main RapidRepository namespace. Various internal methods have been actually made ‘internal’ and replaced with a more friendly API (I imagine not many users will notice this change). Hope you like it Kind Regards, Sean McAlinden

• Estudio de caso: CFO de At&T le apunta a la tecnología para transformar las Finanzas Globales

  - by RED League Heroes-Oracle

  AT&T es una de las pocas multinacionales modernas que han participado de todas las etapas anteriores de la innovación de las telecomunicaciones, de Alexander Graham Bell como inventor solitario, a Bell Labs, a los lanzamientos acelerados en las fundiciones de AT&T. La tecnología es el corazón de todo lo que AT&T hace, incluyendo sus inversiones en innovaciones tecnológicas para permitir que las finanzas de AT&T trabajen más estratégicamente con los negocios para asegurar que las inversiones en las iniciativas de crecimiento sean exitosas. Según John Stephens, Vicepresidente Ejecutivo y director financiero de AT&T, la empresa ha trazado un plan de inversión de tres años para mejorar y aumentar sus redes IP de banda ancha alámbricas e inalámbricas. El plan incluye la implementación del servicio 4G LTE para 300 millones de personas en los Estados Unidos, expansión de IP de banda ancha de alta velocidad a unos 57 millones de hogares de clientes y una expansión de la fibra a 1 millón de clientes corporativos adicionales en su área de servicio de telefonía fija. "La necesidad de velocidad es mayor que nunca, y este proyecto es nuestro paso hacia la innovación para ofrecer tal velocidad," dice Stephens. Como AT&T moderniza su infraestructura global, sus procesos operacionales se hacen tan poderosos como su red. Ha sido una tarea grande y compleja, pero Stephens se complace al decir que el departamento de finanzas de AT&T ha adoptado su papel de catalizador corporativo. Empezó con un concepto simple: "Vamos a hacer que todos hablen en el mismo idioma". Esto llevó a la consolidación de sistemas financieros heredados de las empresas adquiridas. No fue una tarea sencilla, dado que la empresa pasó por más de cinco adquisiciones importantes y un sinfín de otras transacciones. En 2007, AT&T tenía 17 aplicaciones apenas en la función de cuentas por pagar. Hoy, el número se ha reducido a dos. Asimismo, hubo 50 sistemas de reportes gerenciales oficiales y ahora hay tres, con planes de excluir uno de ellos. Al tener un único lenguaje volcado a las Finanzas en toda la empresa, el equipo de finanzas de AT&T ha eliminado las varias versiones de los mismos datos, reduciendo la posible confusión en las discusiones y en las decisiones de estrategia de negocios. Estos pasos también han reducido los costos y aceleraron la toma de decisiones. "Lo lindo de los sistemas es que permiten que la gente talentosa con habilidades analíticas usen su tiempo en esa zona, en vez de gastar tiempo en recolección, agregación y organización de los datos," señala Stephens. "Tenemos un proceso eficiente y eficaz que hace que nosotros, dejemos a la gente libre para dedicarse a aquello en que son realmente buenos. Y tenemos un equipo de alta calidad y ellos están en su mejor punto cuando son capaces de hacer su función para apoyar a la unidad de negocio”AT&T es una de las pocas multinacionales modernas que han participado de todas las etapas anteriores de la innovación de las telecomunicaciones, de Alexander Graham Bell como inventor solitario, a Bell Labs, a los lanzamientos acelerados en las fundiciones de AT&T.

  Hello ! I am currently reading a book named "3D Graphics with XNA Game Studio 4.0" by Sean James and have some questions to ask : If i create a effect parameter named lets say SpecularPower and have in my effect a variable named SpecularPower , if i do something like effect.Parameters["SpecularPower"].SetValue(3) That wil change the SpecularPower variable in my effect ? And a second question, not regarding the book : If i have a spaceship and i've created a "boost" functionality that speeds up my spaceship, what effects should i implement to create the impresion oh high speed ? I was thinking of making everything except my spaceship blurry but i think there would be something missing . Any ideas ? Regards, Alex Badescu

  Hello, I am doing some work which involves drawing video frames in real time in OpenGL ES. Right now I am using glTexImage2D to transfer the data, in the absence of Pixel Buffer Objects and the like. A below answer suggests that glTexImage2D is always blocking, even if texture object referenced does is not used for any drawing. Is there a way to do a nonblocking texture upload with OpenGL ES (any version)? Thank you very much, Sean

• When OneTug Just Isn&rsquo;t Enough&hellip;

  - by onefloridacoder

  I stole that from the back of a T-shirt I saw at the Orlando Code Camp 2010.  This was my first code camp and my first time volunteering for an event like this as well.  It was an awesome day.  I cannot begin to count the “aaahh”, “I did-not-know I could do that”, in the crowds and for myself.  I think it was a great day of learning for everyone at all levels.  All of the presenters were different and provided great insights into the topics they were presenting.  Here’s a list of the ones that I attended. KodeFuGuru, “Pirates vs. Ninjas” He touched on many good topics to relax some of the ways we think when we are writing out code, and still looks good, readable, etc.  As he pointed out in all of his examples, we might not always realize everything that’s going on under the covers.  He exposed a bug in his own code, and verbalized the mental gymnastics he went through when he knew there was something wrong with one of his IEnumerable implementations.  For me, it was great to hear that someone else labors over these gut reactions to code quickly snapped together, to the point that we rush to the refactor stage to fix what’s bothering us – and learn.  He has some content on extension methods that was very interesting.  My “that is so cool” moment was when he swapped out AddEntity method on an entity class and used a With extension method instead.  Some of the LINQ scales fell off my eyes at that moment, and I realized my own code could be a lot more powerful (and readable) if incorporate a few of these examples at the appropriate times.  And he cautioned as well… “don’t go crazy with this stuff”, there’s a place and time for everything.  One of his examples demo’d toward the end of the talk is on his sight where he’s chaining methods together, cool stuff. Quotes I liked: “Extension Methods - Extension methods to put features back on the model type, without impacting the type.” “Favor Declarative Code” – Check out the ? and ?? operators if you’re not already using them. “Favor Fluent Code” “Avoid Pirate Ninja Zombies!  If you see one run!” I’m definitely going to be looking at “Extract Projection” when I get into VS2010. BDD 101 – Sean Chambers http://github.com/schambers This guy had a whole host of gremlins against him, final score Sean 5, Gremlins 1.  He ran the code samples from his github repo  in the code github code viewer since the PC they school gave him to use didn’t have VS installed. He did a great job of converting the grammar between BDD and TDD, and how this style of development can be used in integration tests as well as the different types of gated builds on a CI box – he didn’t go into a discussion around CI, but we could infer that it could work. Like when we use WSSF, it does cause a class explosion to happen however the amount of code per class it limit to just covering the concern at hand – no more, no less.  As in “When I as a <Role>, expect {something} to happen, because {}”  This keeps us (the developer) from gold plating our solutions and creating less waste.  He basically keeps the code that prove out the requirement to two lines of code.  Nice. He uses SpecUnit to merge this grammar into his .NET projects and gave an overview on how this ties into writing his own BDD tests.  Some folks were familiar with Given / When / Then as story acceptance criteria and here’s how he mapped it: “Given <Context>  When <Something Happens> Then <I expect...>”  There are a few base classes and overrides in the SpecUnit framework that help with setting up the context for each test which looked very handy. Successfully Running Your Own Coding Business The speaker ran through a list of items that sounded like common sense stuff LLC, banking, separating expenses, etc.  Then moved into role playing with business owners and an ISV.  That was pretty good stuff, it pays to be a good listener all of the time even if your client is sitting on the other side of the phone tearing you head off for you – but that’s all it is, and get used to it its par for the course.  Oh, yeah always answer the phone was one simple thing that you can do to move  your business forward.  But like Cory Foy tweeted this week, “If you owe me a lot of money, don’t have a message that says your away for five weeks skiing in Colorado.”  Lots of food for thought that’s on my list of “todo’s and to-don’ts”. Speaker Idol Next, I had the pleasure of helping Russ Fustino tape this part of Code Camp as my primary volunteer opportunity that day.  You remember Russ, “know the code” from the awesome Russ’ Tool Shed series.  He did a great job orchestrating and capturing the Speaker Idol finals.   So I didn’t actually miss any sessions, but was able to see three back to back in one setting.  The idol finalists gave a 10 minute talk and very deep subjects, but different styles of talks.  No one walked away empty handed for jobs very well done.  Russ has details on his site.  The pictures and  video captured is supposed to be published on Channel 9 at a later date.  It was also a valuable experience to see what makes technical speakers effective in their talks.  I picked up quite a few speaking tips from what I heard from the judges and contestants. Design For Developers – Diane Leeper If you are a great developer, you’re probably a lousy designer.  Diane didn’t come to poke holes in what we think we can do with UI layout and design, but she provided some tools we can use to figure out metaphors for visualizing data.  If you need help with that check out Silverlight Pivot – that’s what she was getting at.  I was first introduced to her at one of John Papa’s talks last year at a Lakeland User Group meeting and she’s very passionate about design.  She was able to discuss different elements of Pivot, while to a developer is just looked cool. I believe she was providing the deck from her talk to folks after her talk, so send her an email if you’re interested.   She says she can talk about design for hours and hours – we all left that session believing her.   Rinse and Repeat Orlando Code Camp 2010 was awesome, and would totally do it again.  There were lots of folks from my shop there, and some that have left my shop to go elsewhere.  So it was a reunion of sorts and a great celebration for the simple fact that its great to be a developer and there’s a community that supports and recognizes it as well.  The sponsors were generous and the organizers were very tired, namely Esteban Garcia and Will Strohl who were responsible for making a lot of this magic happen.  And if you don’t believe me, check out the chatter on Twitter.

• Security in Software

  The term security has many meanings based on the context and perspective in which it is used. Security from the perspective of software/system development is the continuous process of maintaining confidentiality, integrity, and availability of a system, sub-system, and system data. This definition at a very high level can be restated as the following: Computer security is a continuous process dealing with confidentiality, integrity, and availability on multiple layers of a system. Key Aspects of Software Security Integrity Confidentiality Availability Integrity within a system is the concept of ensuring only authorized users can only manipulate information through authorized methods and procedures. An example of this can be seen in a simple lead management application.  If the business decided to allow each sales member to only update their own leads in the system and sales managers can update all leads in the system then an integrity violation would occur if a sales member attempted to update someone else’s leads. An integrity violation occurs when a team member attempts to update someone else’s lead because it was not entered by the sales member.  This violates the business rule that leads can only be update by the originating sales member. Confidentiality within a system is the concept of preventing unauthorized access to specific information or tools.  In a perfect world the knowledge of the existence of confidential information/tools would be unknown to all those who do not have access. When this this concept is applied within the context of an application only the authorized information/tools will be available. If we look at the sales lead management system again, leads can only be updated by originating sales members. If we look at this rule then we can say that all sales leads are confidential between the system and the sales person who entered the lead in to the system. The other sales team members would not need to know about the leads let alone need to access it. Availability within a system is the concept of authorized users being able to access the system. A real world example can be seen again from the lead management system. If that system was hosted on a web server then IP restriction can be put in place to limit access to the system based on the requesting IP address. If in this example all of the sales members where accessing the system from the 192.168.1.23 IP address then removing access from all other IPs would be need to ensure that improper access to the system is prevented while approved users can access the system from an authorized location. In essence if the requesting user is not coming from an authorized IP address then the system will appear unavailable to them. This is one way of controlling where a system is accessed. Through the years several design principles have been identified as being beneficial when integrating security aspects into a system. These principles in various combinations allow for a system to achieve the previously defined aspects of security based on generic architectural models. Security Design Principles Least Privilege Fail-Safe Defaults Economy of Mechanism Complete Mediation Open Design Separation Privilege Least Common Mechanism Psychological Acceptability Defense in Depth Least Privilege Design PrincipleThe Least Privilege design principle requires a minimalistic approach to granting user access rights to specific information and tools. Additionally, access rights should be time based as to limit resources access bound to the time needed to complete necessary tasks. The implications of granting access beyond this scope will allow for unnecessary access and the potential for data to be updated out of the approved context. The assigning of access rights will limit system damaging attacks from users whether they are intentional or not. This principle attempts to limit data changes and prevents potential damage from occurring by accident or error by reducing the amount of potential interactions with a resource. Fail-Safe Defaults Design PrincipleThe Fail-Safe Defaults design principle pertains to allowing access to resources based on granted access over access exclusion. This principle is a methodology for allowing resources to be accessed only if explicit access is granted to a user. By default users do not have access to any resources until access has been granted. This approach prevents unauthorized users from gaining access to resource until access is given. Economy of Mechanism Design PrincipleThe Economy of mechanism design principle requires that systems should be designed as simple and small as possible. Design and implementation errors result in unauthorized access to resources that would not be noticed during normal use. Complete Mediation Design PrincipleThe Complete Mediation design principle states that every access to every resource must be validated for authorization. Open Design Design PrincipleThe Open Design Design Principle is a concept that the security of a system and its algorithms should not be dependent on secrecy of its design or implementation Separation Privilege Design PrincipleThe separation privilege design principle requires that all resource approved resource access attempts be granted based on more than a single condition. For example a user should be validated for active status and has access to the specific resource. Least Common Mechanism Design PrincipleThe Least Common Mechanism design principle declares that mechanisms used to access resources should not be shared. Psychological Acceptability Design PrincipleThe Psychological Acceptability design principle refers to security mechanisms not make resources more difficult to access than if the security mechanisms were not present Defense in Depth Design PrincipleThe Defense in Depth design principle is a concept of layering resource access authorization verification in a system reduces the chance of a successful attack. This layered approach to resource authorization requires unauthorized users to circumvent each authorization attempt to gain access to a resource. When designing a system that requires meeting a security quality attribute architects need consider the scope of security needs and the minimum required security qualities. Not every system will need to use all of the basic security design principles but will use one or more in combination based on a company’s and architect’s threshold for system security because the existence of security in an application adds an additional layer to the overall system and can affect performance. That is why the definition of minimum security acceptably is need when a system is design because this quality attributes needs to be factored in with the other system quality attributes so that the system in question adheres to all qualities based on the priorities of the qualities.

• MySQL: "UPDATE command denied to user ''@'localhost'"

  - by Uncle Nerdicus

  For some reason when I installed MySQL on my machine (a Mac running OS X 10.9) the 'root' MySQL account got messed up and I don't have access to it, but I do have access to the standard MySQL account 'sean@localhost' which I use to log into phpMyAdmin. I am trying to reset the 'root' password by starting the mysqld daemon using the command mysqld --skip-grant-tables and then running the following lines in the mysql shell. mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass') -> WHERE User='root'; mysql> FLUSH PRIVILEGES; Problem is when I try to run that MySQL string the daemon spits back a ERROR 1142 (42000): UPDATE command denied to user ''@'localhost' for table 'user' as if I didn't use the -u argument when I started the mysql shell, either though I did. Any help is muchly appreciated as I am lost at this point. :/
