• What standard superseded 830-1998?

  - by user1564158

  I have been looking into how to document software projects more formally, and I have learned about IEEE 830-1998: Recommended Practice for Software Requirements Specifications. However, as you can see from that link, it has been superseded. I know that 830-1998, and probably even 830-1993, are probably just fine for use. However, if nothing else, I would like to know what standard has superseded it. In this case it may not matter, but if other standards are superseded for more technical things, I think it would be a good idea to link somewhere what standard superseded another (if it is not another one in the same line (830, in this case)). It is worth mentioning that: The most recent standard when searching for "Software Requirements Specifications" or "Software Requirements" on the IEEE Standards Association website is 830-1993, The 2004 (current) version of SWEBOK references 830-1993 (paragraph 2.5), The document's Wikipedia article doesn't mention that the standard was superseded. TLDR: How do you find what standard superseded another, and which one took 830-1998's place?

• Screencast: "Unlocking the Java EE Platform with HTML5"

  - by Geertjan

  The Java EE platform aims to increase your productivity and reduce the amount of scaffolding code needed in Java enterprise applications. It encompasses a range of specifications, such as JPA, EJB, JSF, and JAX-RS. How do these specifications fit together in an application, and how do they relate to each other? And how can HTML5 be used to leverage Java EE? In this recording of a session I did last week at Oredev in Malmo, Sweden, you learn how Java EE works and how it can be integrated with HTML5 front ends, via HTML, JavaScript, and CSS.

• Configuring Vmware virtual machines to run under different IPs and PC specs

  - by Alex

  Right now I'm using a simple VmWare virtual machine with preinstalled Win 7. The IP is assigned automatically (it's the same as main OS IP). Is it possible to create several virtual machines that have different hardware specifications and different IP addresses? Here is what I mean regarding these issues: Specs: Certainly, you can easily change some specifications in the Settings menu (RAM size, HDD size), but what about advanced settings? For example: advanced settings for the Processor: is it AMD (2500+,4000+, etc.. ) or Intel (core 2, Pentium, etc..) Ram - is it Corsair 4 Gb 1333 Mhz or Kingston 2 x 2 Gb 866Mhz or something else? Hdd - Is it Seagate Barracuda 80 gb 5400 Rpm or is it Samsung 500Gb 7200 Rpm or some random SSD? Programs that work under a Virtual Machine shouldn't have a clue if that's a VmWare or not. IPs: Every program that's launched under main OS use the real IP: 93.56.xx.xx All programs that are launched under virtual machine A use IP 1: 74.78.xx.xx All programs that are launched under virtual machine B use IP 2: 84.159.xx.xx I believe that you have to use either VPN or Proxy to solve this problem. The Sum Up: The idea is to create 2-3 independent virtual machines with different hardware specifications and IP addresses. Programs that work under a certain Virtual Machine shouldn't have a clue if that's a VmWare or the real PC. Any ideas/tips or experience regarding configuration will be appreciated!

• Planning development when academic research is involved

  - by Another Anonymous User

  Dear fellow programmers, how do you do "software planning" when academic research is involved? And, on a side note, how do you convince your boss that writing software is not like building a house and it's more like writing a novel? The gory details are below. I am in charge of a small dev team working in a research lab. We started developing a software with the purpose of going public one day (i.e. sell and make money off that). Such software depends on, amongst other things, at least two independent research lines: that is, there are at least two Ph.D. candidates that will, hopefully, one day come out with a working implementation of what we need. The main software depends also on other, more concrete resources that we as developers can take care of: graphics rendering, soft bodies deformation, etc. My boss asked me to write the specifications, requirements AND a bloody GANTT chart of the entire project. Faced with the fact that I don't have a clue about the research part, and that such research is fundamental for the software, he said "make assumptions." For the clarity of the argument, he is a professor whose Ph.D. students should come up with the research we need. And he comes from a strictly engineering background: plan everything first, write down specifications and only then write down code that "it's the last part". What I am doing now: I broke down the product in features; each 'feature' is, de facto, a separate product; Each feature is built on top of the previous one; Once a feature (A) has a working prototype the team can start working on the next feature (B), while QA for is being done for A (if money allows, more people can be brought in, etc.); Features that depend on research will come last: by then, hopefully, the research part will be completed (when is still a big question) ; Also, I set the team to use SCRUM for the development of 'version 1.0', due in a few months. This deadline could be set based on reasonable assumptions: we listed all required features, we counted our availability, and we gave a reasonable estimate. So my questions, again, are: How do I make my boss happy while at the same time get something out the door? How do I write specifications for something we -the developers- have no clue whether it's possible to do or not? (We still haven't decided which libraries to use for some tasks; we'll do so when we'll need to) How do I get the requirements for that, given that there are yet no clients nor investors, just lots of interests and promises? How do I get peace in the world? I am sure at least one of my questions will be answered :) ps: I am writing this anonymously since a potential investor might backfire if this is discovered. Hope you'll understand. However I must say I do not like this mentality of 'hiding the truth': this program will likely benefit many, and not being able to talk openly about this (with my name and my reputation attached) feels like censorship. But alas, I care more about your suggestions now.

• Syntax Highlighting for Gherkin (Cucumber Language)

  - by Liam McLennan

  SyntaxHighlighter is the de facto standard for syntax highlighting on the web. I am currently working on a tool for publishing BDD specifications on the web and I want syntax highlighting. Unfortunately, SyntaxHighlighter does not support Gherkin, the language Cucumber and SpecFlow use to define BDD specifications. Writing new language parsers for SyntaxHighlighter is very easy, so I implemented one for Gherkin. Here is what a syntax highlighted Gherkin file looks like: # A comment here Feature: Some terse yet descriptive text of what is desired In order to realize a named business value As a explicit system actor I want to gain some beneficial outcome which furthers the goal @secretlabel Scenario: Some determinable business situation Given some precondition And some other precondition When some action by the actor And some other action And yet another action Then some testable outcome is achieved And something else we can check happens too Like all SyntaxHighlighter brushes to use this one you need to install the brush (shBrushGherkin.js). I have also used a custom theme to get it just the way I wanted it (shThemeGherkin.css). If you would like to use my Gherkin brush you may download the code and example page.

• Shuffling algorithm with no "self-mapping"?

  - by OregonTrail

  To randomly shuffle an array, with no bias towards any particular permutation, there is the Knuth Fischer-Yeats algorithm. In Python: #!/usr/bin/env python import sys from random import randrange def KFYShuffle(items): i = len(items) - 1 while i > 0: j = randrange(i+1) # 0 <= j <= i items[j], items[i] = items[i], items[j] i = i - 1 return items print KFYShuffle(range(int(sys.argv[1]))) There is also Sattolo's algorithm, which produces random cycles. In Python: #!/usr/bin/env python import sys from random import randrange def SattoloShuffle(items): i = len(items) while i > 1: i = i - 1 j = randrange(i) # 0 <= j <= i-1 items[j], items[i] = items[i], items[j] return items print SattoloShuffle(range(int(sys.argv[1]))) I'm currently writing a simulation with the following specifications for a shuffling algorithm: The algorithm is unbiased. If a true random number generator was used, no permutation would be more likely than any other. No number ends up at its original index. The input to the shuffle will always be A[i] = i for i from 0 to N-1 Permutations are produced that are not cycles, but still meet specification 2. The cycles produced by Sattolo's algorithm meet specification 2, but not specification 1 or 3. I've been working at creating an algorithm that meets these specifications, what I came up with was equivalent to Sattolo's algorithm. Does anyone have an algorithm for this problem?

• BDD/TDD vs JAD?

  - by Jonathan Conway

  I've been proposing that my workplace implement Behavior-Driven-Development, by writing high-level specifications in a scenario format, and in such a way that one could imagine writing a test for it. I do know that working against testable specifications tends to increase developer productivity. And I can already think of several examples where this would be the case on our own project. However it's difficult to demonstrate the value of this to the business. This is because we already have a Joint Application Development (JAD) process in place, in which developers, management, user-experience and testers all get together to agree on a common set of requirements. So, they ask, why should developers work against the test-cases created by testers? These are for verification and are based on the higher-level specs created by the UX team, which the developers currently work off. This, they say, is sufficient for developers and there's no need to change how the specs are written. They seem to have a point. What is the actual benefit of BDD/TDD, if you already have a test-team who's test cases are fully compatible with the higher-level specs currently given to the developers?

• Variant Management– Which Approach fits for my Product?

  - by C. Chadwick

  Jürgen Kunz – Director Product Development – Oracle ORACLE Deutschland B.V. & Co. KG Introduction In a difficult economic environment, it is important for companies to understand the customer requirements in detail and to address them in their products. Customer specific products, however, usually cause increased costs. Variant management helps to find the best combination of standard components and custom components which balances customer’s product requirements and product costs. Depending on the type of product, different approaches to variant management will be applied. For example the automotive product “car” or electronic/high-tech products like a “computer”, with a pre-defined set of options to be combined in the individual configuration (so called “Assembled to Order” products), require a different approach to products in heavy machinery, which are (at least partially) engineered in a customer specific way (so-called “Engineered-to Order” products). This article discusses different approaches to variant management. Starting with the simple Bill of Material (BOM), this article presents three different approaches to variant management, which are provided by Agile PLM. Single level BOM and Variant BOM The single level BOM is the basic form of the BOM. The product structure is defined using assemblies and single parts. A particular product is thus represented by a fixed product structure. As soon as you have to manage product variants, the single level BOM is no longer sufficient. A variant BOM will be needed to manage product variants. The variant BOM is sometimes referred to as 150% BOM, since a variant BOM contains more parts and assemblies than actually needed to assemble the (final) product – just 150% of the parts You can evolve the variant BOM from the single level BOM by replacing single nodes with a placeholder node. The placeholder in this case represents the possible variants of a part or assembly. Product structure nodes, which are part of any product, are so-called “Must-Have” parts. “Optional” parts can be omitted in the final product. Additional attributes allow limiting the quantity of parts/assemblies which can be assigned at a certain position in the Variant BOM. Figure 1 shows the variant BOM of Agile PLM. Figure 1 Variant BOM in Agile PLM During the instantiation of the Variant BOM, the placeholders get replaced by specific variants of the parts and assemblies. The selection of the desired or appropriate variants is either done step by step by the user or by applying pre-defined configuration rules. As a result of the instantiation, an independent BOM will be created (Figure 2). Figure 2 Instantiated BOM in Agile PLM This kind of Variant BOM  can be used for „Assembled –To-Order“ type products as well as for „Engineered-to-Order“-type products. In case of “Assembled –To-Order” type products, typically the instantiation is done automatically with pre-defined configuration rules. For „Engineered- to-Order“-type products at least part of the product is selected manually to make use of customized parts/assemblies, that have been engineered according to the specific custom requirements. Template BOM The Template BOM is used for „Engineered-to-Order“-type products. It is another type of variant BOM. The engineer works in a flexible environment which allows him to build the most creative solutions. At the same time the engineer shall be guided to re-use existing solutions and it shall be assured that product variants of the same product family share the same base structure. The template BOM defines the basic structure of products belonging to the same product family. Let’s take a gearbox as an example. The customer specific configuration of the gearbox is influenced by several parameters (e.g. rpm range, transmitted torque), which are defined in the customer’s requirement document.  Figure 3 shows part of a Template BOM (yellow) and its relation to the product family hierarchy (blue).  Figure 3 Template BOM Every component of the Template BOM has links to the variants that have been engineeried so far for the component (depending on the level in the Template BOM, they are product variants, Assembly Variant or single part variants). This library of solutions, the so-called solution space, can be used by the engineers to build new product variants. In the best case, the engineer selects an existing solution variant, such as the gearbox shown in figure 3. When the existing variants do not fulfill the specific requirements, a new variant will be engineered. This new variant must be compliant with the given Template BOM. If we look at the gearbox in figure 3  it must consist of a transmission housing, a Connecting Plate, a set of Gears and a Planetary transmission – pre-assumed that all components are must have components. The new variant will enhance the solution space and is automatically available for re-use in future variants. The result of the instantiation of the Template BOM is a stand-alone BOM which represents the customer specific product variant. Modular BOM The concept of the modular BOM was invented in the automotive industry. Passenger cars are so-called „Assembled-to-Order“-products. The customer first selects the specific equipment of the car (so-called specifications) – for instance engine, audio equipment, rims, color. Based on this information the required parts will be determined and the customer specific car will be assembled. Certain combinations of specification are not available for the customer, because they are not feasible from technical perspective (e.g. a convertible with sun roof) or because the combination will not be offered for marketing reasons (e.g. steel rims with a sports line car). The modular BOM (yellow structure in figure 4) is defined in the context of a specific product family (in the sample it is product family „Speedstar“). It is the same modular BOM for the different types of cars of the product family (e.g. sedan, station wagon). The assembly or single parts of the car (blue nodes in figure 4) are assigned at the leaf level of the modular BOM. The assignment of assembly and parts to the modular BOM is enriched with a configuration rule (purple elements in figure 4). The configuration rule defines the conditions to use a specific assembly or single part. The configuration rule is valid in the context of a type of car (green elements in figure 4). Color specific parts are assigned to the color independent parts via additional configuration rules (grey elements in figure 4). The configuration rules use Boolean operators to connect the specifications. Additional consistency rules (constraints) may be used to define invalid combinations of specification (so-called exclusions). Furthermore consistency rules may be used to add specifications to the set of specifications. For instance it is important that a car with diesel engine always is build using the high capacity battery.  Figure 4 Modular BOM The calculation of the car configuration consists of several steps. First the consistency rules (constraints) are applied. Resulting from that specification might be added automatically. The second step will determine the assemblies and single parts for the complete structure of the modular BOM, by evaluating the configuration rules in the context of the current type of car. The evaluation of the rules for one component in the modular BOM might result in several rules being fulfilled. In this case the most specific rule (typically the longest rule) will win. Thanks to this approach, it is possible to add a specific variant to the modular BOM without the need to change any other configuration rules.  As a result the whole set of configuration rules is easy to maintain. Finally the color specific assemblies respective parts will be determined and the configuration is completed. Figure 5 Calculated Car Configuration The result of the car configuration is shown in figure 5. It shows the list of assemblies respective single parts (blue components in figure 5), which are required to build the customer specific car. Summary There are different approaches to variant management. Three different approaches have been presented in this article. At the end of the day, it is the type of the product which decides about the best approach.  For „Assembled to Order“-type products it is very likely that you can define the configuration rules and calculate the product variant automatically. Products of type „Engineered-to-Order“ ,however, need to be engineered. Nevertheless in the majority of cases, part of the product structure can be generated automatically in a similar way to „Assembled to Order“-tape products.  That said it is important first to analyze the product portfolio, in order to define the best approach to variant management.

  - by drrwebber

  XML Component Dictionary capabilities are provided in conjunction with the CAM Editor toolset.  These dictionaries accelerate the development of consistent XML information exchanges using standard sets of dictionary components. The quick tutorials are aimed at showing the 'how to' of the basic capabilities to jump start use of XML dictionaries with the CAM Editor. The collection of dictionary tutorials videos run for a total of approximately 20 minutes.  Each video can be reviewed individually also. Learn how to use the dictionary functions to create dictionaries by harvesting data model components from existing XSD schema, SQL database table schema, or simple Excel / Open Office spreadsheets with tables of components listed.Also included are tips and functions relating to use of NIEM exchange development, IEPD and EIEM techniques.These videos should be viewed in conjunction with reviewing the overall concepts and techniques described in the companion video on the CAM Editor and Dictionaries overview.  The approach is aligned with OASIS and Core Components Technical Specification (CCTS) standards specifications for XML components and dictionaries.Dictionary collections can be stored locally on the file system, or local network, or collaboratively on the web or cloud deployment, or can be shared and managed securely using the Oracle Enterprise Repository (OER) tool. Also included are techniques relating to the use of the NIEM approach for developing XML exchange schema and IEPD packages.  This includes generating reuse scores, wantlist, and cross reference spreadsheets. Included in the latest release of the CAM Editor is the ability to use the analyse dictionary tool to determine duplicate components, conflicting component definitions, missing component descriptions and so on.  This ensures high quality dictionary component specifications.  Using the CAM Editor you can also create MindMap models and UML physical models of your dictionary components sets. For a complete guide to using the CAM Editor see the main YouTube video tutorials website and the CAM Editor website.

• Ubuntu (i386 - 32bit) 12.04 LTS [DESKTOP] - Freezes During Preparing to Install

  - by Michael Ecklund

  I know this is for the Desktop version of Ubuntu, but I definitely plan on installing the server as well. I just want a GUI to manage my server. Here is what I have done: Placed Ubuntu i386/32bit 12.04 LTS [DESKTOP] disc in the disc tray. The disc loads fine. Clicked install Ubuntu. Without checking the download updates while installing or install this third-party software. Clicked continue. Mouse cursor turns to spinning circle and remains a spinning circle while the screen freezes its place at "Preparing to install Ubuntu". I tried not checking any of the boxes and clicking continue. I tried checking Download updates while installing. I tried checking Install this third-party software. I tried checking BOTH Download updates while installing AND Install this third-party software. Does anyone else face this very same issue? Is there a workaround for this problem? Do I need to use a lower version of Ubuntu? If so, which version do you recommend for my system specifications? My system meets the system requirements. Here are my exact system specifications. (Custom modifications: 320GBx2 HDD && 256MB AGP GFX card && 1GBx2 RAM)

• Fastest Memory (within reason) for a MotherBoard [on hold]

  - by sampson

  I was wondering if it would be OK to use DDR3 3000 memory with Asus Maximus VI Impact MotherBoard, Intel® Core™ i3-4130T Processor and Steamcom's FC8 case The purpose of this machine is for a HTPC (Home Theater Personal Computer) system, only, no gaming. The case is fan less as is the CPU cooling system. Also, would it be worth it, heat wise, to go past the 1600 memory type? I mean, would DDR 3000 make the box that much faster to make it worthwhile? The Processor has a TDP rating of 35 W. The memory specifications for the processor are: Memory Specifications Max Memory Size (dependent on memory type) 32 GB Memory Types DDR3-1333/1600 # of Memory Channels 2 Max Memory Bandwidth 25.6 GB/s ECC Memory Supported ‡ Yes The FC8 case's heat displacement system is rated at 95 W TDP

• HTML5 and Visual Studio 2010

  - by Harish Ranganathan

  All of us work with Visual Studio (or the free Visual Web Developer Express Edition) for developing web applications targeting ASP.NET / ASP.NET MVC or Silverlight etc.,  Over the years, Visual Studio has grown to a great extent.  From being a simple limited functionality tool in VS.NET 2002 to the multi-faceted, MEF driven Visual Studio 2010, it has come a long way.  And as much as Visual Studio supports rapid web development by generating HTML mark up, it also added intellisense for some of the HTML specifications that one has otherwise monotonously type every time.  Ex.- In Visual Studio 2010, one can just type the angular bracket “<” and then the first keyword “h” or “x” for html or xhtml respectively and then press tab twice and it would render the entire markup required for XHTML or HTML 1.0/1.1 strict/transitional and the fully qualified W3C URL. The same holds good for specifying HTML type declaration.  Now, the difference between HTML and XHTML has been discussed in detail already, though, if you are interested to know, you can read it from http://www.w3schools.com/xhtml/xhtml_html.asp But, the industry trend or the buzz around is HTML5.  With browsers like IE9 Beta, Google Chrome, Firefox 4 etc., supporting HTML5 standards big time, everyone wants to start developing HTML5 based websites. VS developers (like me) often get the question around when would VS start supporting HTML5.  VS 2010 was released last year and HTML5 is still specifications under development.  Clearly, with the timelines we started developing Visual Studio (way back in 2008), HTML5 specs were almost non-existent.  Even today, the HTML5 body recommends not to fully depend on the entire mark up set as they are still under development specs and might change in the future. However, with Visual Studio 2010 SP1 beta, there is quite a bit of support for HTML5 based web development.  In fact, one of my colleagues pointed out that SP1 beta’s major enhancement is its ability to support HTML5 tags and even add server mode to them. Lets look at the existing validation schema available in Visual Studio (Tools – Options – Validation) This is before installing Visual Studio 2010 SP1 Beta.  Clearly, the validation options are restricted to HTML 4.01 and XHTML 1.1 transitional and below. Also, lets consider using some of the new HTML5 input type elements.  (I found out this, just today from my friend, also an, ASP.NET team member) <input type=”email”> is one of the new input type elements according to the HTML5 specification.  Now, this works well if you type it as is  in Visual Studio and the page renders without any issue (since the default behaviour is, if there is an “undefined” type specified to input tag, it would fall back on the default mode, which is text. The moment you add <input type=”email” runat=”server” >, you get an error Naturally you don’t get intellisense support as well for these new tags.  Once you install Visual Studio 2010 Service Pack 1 Beta from here (it takes a while so you need to be patient for the installation to complete), you will start getting additional Validation templates for HTML5, as below:- Once you set this, you can start using HTML5 elements in your web page without getting errors/warnings.  Look at the screen shot below, for the new “video” tag which is showing up in intellisense (video is a part of the new HTML5 specifications)     note that, you still need to hook up the <!DOCTYPE html /> on the top manually as it doesn’t change automatically  (from the default XHTML 1.0 strict) when you create a new page. Also, the new input type tags in HTML5 are also supported One, can also use the <asp:TextBox type=”email” which would in turn generate the <input type=”email”> markup when the page is rendered.  In fact, as of SP1 beta, this is the only way to put the new input type tags with the runat=”server” attribute (otherwise you will get the parser error mentioned above.  This issue would be fixed by the final release of SP1 beta) Going further, there may be more support for having server tags for some of the common HTML5 elements, but this is work in progress currently. So, other than not having runat=”server” support for the new HTML5  input tags, you can pretty much build and target HTML5 websites with Visual Studio 2010 SP1 Beta, today.  For those who are running Visual Studio 2008, you also have the “HTML5 intellisense for Visual Studio 2010 and 2008” available for download, from http://visualstudiogallery.msdn.microsoft.com/d771cbc8-d60a-40b0-a1d8-f19fc393127d/ Note that, if you are running Visual Studio 2010, the recommended approach is to install the SP1 beta which would be the way forward for HTML5 support in Visual Studio. Of course, you need to test these on a browser supporting HTML5 such as IE9 Beta or Chrome or FireFox 4.  You can download IE9 Beta from here You can also follow the Visual Web Developer Team Blog for more updates on the stuff they are building. Cheers !!!

• My Feelings About Microsoft Surface

  - by Valter Minute

  Advice: read the title carefully, I’m talking about “feelings” and not about advanced technical points proved in a scientific and objective way I still haven’t had a chance to play with a MS Surface tablet (I would love to, of course) and so my ideas just came from reading different articles on the net and MS official statements. Remember also that the MVP motto begins with “Independent” (“Independent Experts. Real World Answers.”) and this is just my humble opinion about a product and a technology. I know that, being an MS MVP you can be called an “MS-fanboy”, I don’t care, I hope that people can appreciate my opinion, even if it doesn’t match theirs. The “Surface” brand can be confusing for techies that knew the “original” surface concept but I think that will be a fresh new brand name for most of the people out there. But marketing department are here to confuse people… so I can understand this “recycle” of an existing name. So Microsoft is entering the hardware arena… for me this is good news. Microsoft developed some nice hardware in the past: the xbox, zune (even if the commercial success was quite limited) and, last but not least, the two arc mices (old and new model) that I use and appreciate. In the past Microsoft worked with OEMs and that model lead to good and bad things. Good thing (for microsoft, at least) is market domination by windows-based PCs that only in the last years has been reduced by the return of the Mac and tablets. Google is also moving in the hardware business with its acquisition of Motorola, and Apple leveraged his control of both the hardware and software sides to develop innovative products. Microsoft can scare OEMs and make them fly away from windows (but where?) or just lead the pack, showing how devices should be designed to compete in the market and bring back some of the innovation that disappeared from recent PC products (look at the shelves of your favorite electronics store and try to distinguish a laptop between the huge mass of anonymous PCs on displays… only Macs shine out there…). Having to compete with MS “official” hardware will force OEMs to develop better product and bring back some real competition in a market that was ruled only by prices (the lower the better even when that means low quality) and no innovative features at all (when it was the last time that a new PC surprised you?). Moving into a new market is a big and risky move, but with Windows 8 Microsoft is playing a crucial move for its future, trying to be back in the innovation run against apple and google. MS can’t afford to fail this time. I saw the new devices (the WinRT and Pro) and the specifications are scarce, misleading and confusing. The first impression is that the device looks like an iPad with a nice keyboard cover… Using “HD” and “full HD” to define display resolution instead of using the real figures and reviving the “ClearType” brand (now dead on Win8 as reported here and missed by people who hate to read text on displays, like myself) without providing clear figures (couldn’t you count those damned pixels?) seems to imply that MS was caught by surprise by apple recent “retina” displays that brought very high definition screens on tablets.Also there are no specifications about the processors used (even if some sources report NVidia Tegra for the ARM tablet and i5 for the x86 one) and expected battery life (a critical point for tablets and the point that killed Windows7 x86 based tablets). Also nothing about the price, and this will be another critical point because other platform out there already provide lots of applications and have a good user base, if MS want to enter this market tablets pricing must be competitive. There are some expansion ports (SD and USB), so no fixed storage model (even if the specs talks about 32-64GB for RT and 128-256GB for pro). I like this and don’t like the apple model where flash memory (that it’s dirt cheap used in thumdrives or SD cards) is as expensive as gold (or cocaine to have a more accurate per gram measurement) when mounted inside a tablet/phone. For big files you’ll be able to use external media and an SD card could be used to store files that don’t require super-fast SSD-like access times, I hope. To be honest I really don’t like the marketplace model and the limitation of Windows RT APIs (no local database? from a company that based a good share of its success on VB6+Access!) and lack of desktop support on the ARM (even if the support is here and has been used to port office). It’s a step toward the consumer market (where competitors are making big money), but may impact enterprise (and embedded) users that may not appreciate Windows 8 new UI or the limitations of the new app model (if you aren’t connected you are dead ). Not having compatibility with the desktop will require brand new applications and honestly made all the CPU cycles spent to convert .NET IL into real machine code in the past like a huge waste of time… as soon as a new processor architecture is supported by Windows you still have to rewrite part of your application (and MS is pushing HTML5+JS and native code more than .NET in my perception). On the other side I believe that the development experience provided by Visual Studio is still miles (or kilometres) ahead of the competition and even the all-uppercase menu of VS2012 hasn’t changed this situation. The new metro UI got mixed reviews. On my side I should say that is very pleasant to use on a touch screen, I like the minimalist design (even if sometimes is too minimal and hides stuff that, in my opinion, should be visible) but I should also say that using it with mouse and keyboard is like trying to pick your nose with boxing gloves… Metro is also very interesting for embedded devices where touch screen usage is quite common and where having an application taking all the screen is the norm. For devices like kiosks, vending machines etc. this kind of UI can be a great selling point. I don’t need a new tablet (to be honest I’m pretty happy with my wife’s iPad and with my PC), but I may change my opinion after having a chance to play a little bit with those new devices and understand what’s hidden under all this mysterious and generic announcements and specifications!

• Dealing with a badly formatted CSV file

  - by Josh K

  I have an exceptionally bad CSV file. Although I "solved" the problem in the end by manually writing scripts to process and reprocess this specific file I wanted to know if there were any other solutions out there. You have a CSV file that has all the fields terminated by | (pipe) characters. Running a quick check shows you that there are 53 fields in the file. The person who gave you the file claims there there are only 28 fields. Not all of the fields have information in them. For example there are five custom_field_{num} fields which may or may not have data. How would you get this into a database nicely? The ideal solution (and one I searched high and low for) would be to just throw it all into a table with no column names or specifications. Then remove any columns that were completely blank and then give them titles and specifications.

• BlackBerry Technical Specification

  - by Sam

  I'm having trouble locating BlackBerry techical specifications and their website is a mess. They also don't have a number that I can use to easily contact them. This isn't exactly a coding question, but what does the BlackBerry audio API look like, and where can I get technical specifications on audio? Specifically, I'm trying to find out more information on Audio-In, specifically, through the Mic-In on the 3.5 mm jack. Unfortunately, before I can proceed, I need to know such things like sampling rate, data width, etc. Direction to the right resource or if you know off of the top of your head is appreciated.

• MS DOS function like ipconfig to get system performance specs?

  - by JustADude

  I am aware of MSINFO32, but I'm wondering if there is a MS DOS command similar to ipconfig in order to get system specifications? I would like for the system specifications to be displayed in the MS DOS prompt. I would like to see at least: CPU RAM BUS speed Thanks for any insights. Edit: I am unable to install any other software, so just have to use existing DOS programming commands to extract this information. Thank you again. 2nd Edit: Whoops. Using Windows XP and Windows Vista.

• AuthnRequest Settings in OIF / SP

  - by Damien Carru

  In this article, I will list the various OIF/SP settings that affect how an AuthnRequest message is created in OIF in a Federation SSO flow. The AuthnRequest message is used by an SP to start a Federation SSO operation and to indicate to the IdP how the operation should be executed: How the user should be challenged at the IdP Whether or not the user should be challenged at the IdP, even if a session already exists at the IdP for this user Which NameID format should be requested in the SAML Assertion Which binding (Artifact or HTTP-POST) should be requested from the IdP to send the Assertion Which profile should be used by OIF/SP to send the AuthnRequest message Enjoy the reading! Protocols The SAML 2.0, SAML 1.1 and OpenID 2.0 protocols define different message elements and rules that allow an administrator to influence the Federation SSO flows in different manners, when the SP triggers an SSO operation: SAML 2.0 allows extensive customization via the AuthnRequest message SAML 1.1 does not allow any customization, since the specifications do not define an authentication request message OpenID 2.0 allows for some customization, mainly via the OpenID 2.0 extensions such as PAPE or UI SAML 2.0 OIF/SP allows the customization of the SAML 2.0 AuthnRequest message for the following elements: ForceAuthn: Boolean indicating whether or not the IdP should force the user for re-authentication, even if the user has still a valid session By default set to false IsPassive Boolean indicating whether or not the IdP is allowed to interact with the user as part of the Federation SSO operation. If false, the Federation SSO operation might result in a failure with the NoPassive error code, because the IdP will not have been able to identify the user By default set to false RequestedAuthnContext Element indicating how the user should be challenged at the IdP If the SP requests a Federation Authentication Method unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the NoAuthnContext error code By default missing NameIDPolicy Element indicating which NameID format the IdP should include in the SAML Assertion If the SP requests a NameID format unknown to the IdP or for which the IdP is not configured, then the Federation SSO flow will result in a failure with the InvalidNameIDPolicy error code If missing, the IdP will generally use the default NameID format configured for this SP partner at the IdP By default missing ProtocolBinding Element indicating which SAML binding should be used by the IdP to redirect the user to the SP with the SAML Assertion Set to Artifact or HTTP-POST By default set to HTTP-POST OIF/SP also allows the administrator to configure the server to: Set which binding should be used by OIF/SP to redirect the user to the IdP with the SAML 2.0 AuthnRequest message: Redirect or HTTP-POST By default set to Redirect Set which binding should be used by OIF/SP to redirect the user to the IdP during logout with SAML 2.0 Logout messages: Redirect or HTTP-POST By default set to Redirect SAML 1.1 The SAML 1.1 specifications do not define a message for the SP to send to the IdP when a Federation SSO operation is started. As such, there is no capability to configure OIF/SP on how to affect the start of the Federation SSO flow. OpenID 2.0 OpenID 2.0 defines several extensions that can be used by the SP/RP to affect how the Federation SSO operation will take place: OpenID request: mode: String indicating if the IdP/OP can visually interact with the user checkid_immediate does not allow the IdP/OP to interact with the user checkid_setup allows user interaction By default set to checkid_setup PAPE Extension: max_auth_age : Integer indicating in seconds the maximum amount of time since when the user authenticated at the IdP. If MaxAuthnAge is bigger that the time since when the user last authenticated at the IdP, then the user must be re-challenged. OIF/SP will set this attribute to 0 if the administrator configured ForceAuthn to true, otherwise this attribute won't be set Default missing preferred_auth_policies Contains a Federation Authentication Method Element indicating how the user should be challenged at the IdP By default missing Only specified in the OpenID request if the IdP/OP supports PAPE in XRDS, if OpenID discovery is used. UI Extension Popup mode Boolean indicating the popup mode is enabled for the Federation SSO By default missing Language Preference String containing the preferred language, set based on the browser's language preferences. By default missing Icon: Boolean indicating if the icon feature is enabled. In that case, the IdP/OP would look at the SP/RP XRDS to determine how to retrieve the icon By default missing Only specified in the OpenID request if the IdP/OP supports UI Extenstion in XRDS, if OpenID discovery is used. ForceAuthn and IsPassive WLST Command OIF/SP provides the WLST configureIdPAuthnRequest() command to set: ForceAuthn as a boolean: In a SAML 2.0 AuthnRequest, the ForceAuthn field will be set to true or false In an OpenID 2.0 request, if ForceAuthn in the configuration was set to true, then the max_auth_age field of the PAPE request will be set to 0, otherwise, max_auth_age won't be set IsPassive as a boolean: In a SAML 2.0 AuthnRequest, the IsPassive field will be set to true or false In an OpenID 2.0 request, if IsPassive in the configuration was set to true, then the mode field of the OpenID request will be set to checkid_immediate, otherwise set to checkid_setup Test In this test, OIF/SP is integrated with a remote SAML 2.0 IdP Partner, with the OOTB configuration. Based on this setup, when OIF/SP starts a Federation SSO flow, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> Let's configure OIF/SP for that IdP Partner, so that the SP will require the IdP to re-challenge the user, even if the user is already authenticated: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command:configureIdPAuthnRequest(partner="AcmeIdP", forceAuthn="true") Exit the WLST environment:exit() After the changes, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ForceAuthn="true" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> To display or delete the ForceAuthn/IsPassive settings, perform the following operatons: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the configureIdPAuthnRequest() command: To display the ForceAuthn/IsPassive settings on the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", displayOnly="true") To delete the ForceAuthn/IsPassive settings from the partnerconfigureIdPAuthnRequest(partner="AcmeIdP", delete="true") Exit the WLST environment:exit() Requested Fed Authn Method In my earlier "Fed Authentication Method Requests in OIF / SP" article, I discussed how OIF/SP could be configured to request a specific Federation Authentication Method from the IdP when starting a Federation SSO operation, by setting elements in the SSO request message. WLST Command The OIF WLST commands that can be used are: setIdPPartnerProfileRequestAuthnMethod() which will configure the requested Federation Authentication Method in a specific IdP Partner Profile, and accepts the following parameters: partnerProfile: name of the IdP Partner Profile authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it setIdPPartnerRequestAuthnMethod() which will configure the specified IdP Partner entry with the requested Federation Authentication Method, and accepts the following parameters: partner: name of the IdP Partner authnMethod: the Federation Authentication Method to request displayOnly: an optional parameter indicating if the method should display the current requested Federation Authentication Method instead of setting it delete: an optional parameter indicating if the method should delete the current requested Federation Authentication Method instead of setting it This applies to SAML 2.0 and OpenID 2.0 protocols. See the "Fed Authentication Method Requests in OIF / SP" article for more information. Test In this test, OIF/SP is integrated with a remote SAML 2.0 IdP Partner, with the OOTB configuration. Based on this setup, when OIF/SP starts a Federation SSO flow, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> Let's configure OIF/SP for that IdP Partner, so that the SP will request the IdP to use a mechanism mapped to the urn:oasis:names:tc:SAML:2.0:ac:classes:X509 Federation Authentication Method to authenticate the user: Enter the WLST environment by executing:$IAM_ORACLE_HOME/common/bin/wlst.sh Connect to the WLS Admin server:connect() Navigate to the Domain Runtime branch:domainRuntime() Execute the setIdPPartnerRequestAuthnMethod() command:setIdPPartnerRequestAuthnMethod("AcmeIdP", "urn:oasis:names:tc:SAML:2.0:ac:classes:X509") Exit the WLST environment:exit() After the changes, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/>   <samlp:RequestedAuthnContext Comparison="minimum">      <saml:AuthnContextClassRef xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">         urn:oasis:names:tc:SAML:2.0:ac:classes:X509      </saml:AuthnContextClassRef>   </samlp:RequestedAuthnContext></samlp:AuthnRequest> NameID Format The SAML 2.0 protocol allows for the SP to request from the IdP a specific NameID format to be used when the Assertion is issued by the IdP.

Based on this setup, when OIF/SP starts a Federation SSO flow, the following SAML 2.0 AuthnRequest would be generated: <samlp:AuthnRequest ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" ID="id-E4BOT7lwbYK56lO57dBaqGUFq01WJSjAHiSR60Q4" Version="2.0" IssueInstant="2014-04-01T21:39:14Z" Destination="https://acme.com/saml20/sso">   <saml:Issuer Format="urn:oasis:names:tc:SAML:2.0:nameid-format:entity">https://sp.com/oam/fed</saml:Issuer>   <samlp:NameIDPolicy AllowCreate="true"/></samlp:AuthnRequest> In the next article, I will cover the various crypto configuration properties in OIF that are used to affect the Federation SSO exchanges.Cheers,Damien Carru
