What is compliant code

Fifteen percent volumetric dimensional stability can be analyzed as allowing for about 2. In comparison, the calculated linear dimensional stability limit of 2. I believe linear dimensional stability values, not volumetric dimensional stability values, should be determined for SPF for better comparison with other roof insulation and building components. Simply knowing a manufacturer has an evaluation report is not enough.

There is a difference between code approval and code acceptance. Code approval results from a product meeting specific criteria listed in model building codes. Code acceptance means a product is accepted by a code official for use on a case-by-case basis. When a manufacturer provides an evaluation report for SPF acceptance, the installer must provide this information to the code official having jurisdiction. The code official has the right to accept or deny the product's use.

Manufacturers should provide documentation that includes substantiation for code compliance at the time products are purchased. Otherwise, a read of the variable argument can, itself, expose a vulnerability.

Semantics of volatile do not guarantee the atomicity of compound operations that involve read-modify-write sequences such as incrementing a value. That guarantee requires that no unsynchronized methods in the class expose the value and that the value is inaccessible directly or indirectly from other code. VNAEX2: This guideline can be ignored for systems that guarantee that bit, long and double values are read and written as atomic operations. Failure to ensure the atomicity of operations involving bit values in multithreaded applications can result in reading and writing indeterminate values.

Many JVMs read and write bit values atomically, even though the specification does not require them to. Do not assume that declaring an object reference volatile guarantees visibility of its members. According to the Java Language Specification , Section 8. Notably, this applies only to primitive fields and immutable member objects.

The visibility guarantee does not extend to non-thread-safe mutable objects, even if their references are declared volatile. A thread may not observe a recent write from another thread to a member field of such an object. Declaring an object volatile to ensure the visibility of its state does not work without the use of synchronization, unless the object is immutable.

In the same way that frequently exercising build and deployment steps reduces operational risks, exercising compliance on every change, following the same standardized process and automated steps, reduces the risks of compliance violations. Compliance is not just about security, but it is a major aspect of it.

To explain this a little bit more: developer teams need to strive for compliance e. Compliance related requirements are most often non functional requirements. All of this helps your organization with your regular business processes, thus ensuring business continuity. Compliance rules can be defined by different departments in your organization. Or another one from the CISO department: intranet based application are never to be deployed with a public endpoint e.

It is tedious, time consuming and error prone to check for these rules manually each time a software application is deployed. Once a new version of a software application is deployed, it is evaluated automatically against these rules. As a result the rules should prevent any application from being deployed if the application violates the rules. This way, the process can be repeated for every deployment.

The compliance rules are embedded into the DevOps way of working. Compliance policies are written as code and stored in a source code version control system. One or more rules make up 1 compliance policy. Stakeholders or external regulators define the functional policies, developers implement them.

There are special software tools on the market which help developers write the policies. Above mentioned tools hook up in several stages of the software development life-cycle. In terms of feedback: the faster you know whether or not your software applications are compliant the faster you can fix it. Fixing compliance rules in an earlier stage is also much cheaper than fixing them in production. Compliance rules usually come from non-technical people in the organization. Developers need to translate these rules from a human readable format e.

A key principle here is the decoupling the specification, implementation and enforcement of compliance rules.

Semantic elements - main , nav , section , article , aside , footer should always be used to describe contents of a website instead of using a div. Attributes values should be enclosed in double quotation marks " " rather than single quotation marks ' '. Provide a descriptive alternate text for images. For images used for decorative purposes e. Writing a content in all capital letters signifies shouting.

Lowercase letters should be used for your content likewise elements, attributes and values. Handle all typography and styling using CSS. Naming things can be daunting but pays off in the long run when we get it right. Id and class names should be descriptive. It needs to relate to the content, not the presentation. Peradventure we decide to change the color of notification in the future, it would only affect the CSS file leaving the markup untouched.

However, if the first approach was used, we would need to update the class name within the markup to reflect the change.
