• What strategy to use when starting in a new project with no documentations?

  - by Amir Rezaei

  Which is the best why to go when there are no documentations? For example how do you learn business rules? I have done the following steps: Since we are using a ORM tool I have printed a copy of database schema where I can se relations between objects. I have made a list of short names/table names that I will get explained. The project is client/server enterprise application using MVVM pattern.

• What are the files in /dev/input/ and what they do?

  - by Pouya

  I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

• What level of detail to use in an interface members descriptions?

  - by famousgarkin

  I am extracting interfaces from some classes in .NET, and I am not completely sure about what level of detail of description to use for some of the interface members (properties, methods). An example: interface ISomeInterface { /// <summary> /// Checks if the object is checked out. /// </summary> /// <returns> /// Returns true if the object is checked out, or if the object locking is not enabled, /// otherwise returns false. /// </returns> bool IsObjectCheckedOut(); } class SomeImplementation : ISomeInterface { public bool IsObjectCheckedOut() { // An implementation of the method that returns true if the object is checked out, // or if the object locking is not enabled } } The part in question is the <returns>...</returns> section of the IsObjectCheckedOut description in the interface. Is it ok to include such a detail about return value in the interface itself, as the code that will work with the interface should know exactly what that method will do? All the current implementations of the method will do just that. But is it ok to limit the possible other/future implementations by description this way? Or should this not be included in the interface description, as there is no way to actually ensure that other/future implementations will do exactly this? Is it better to be as general as possible regarding the interface in such circumstances? I am currently inclined to the latter option.

• 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?

• Enforcing Constraints Upon Data Documents of Various Formats

  - by Christopher Berman

  This seems like the sort of problem that must have been solved elegantly long ago, but I haven't the foggiest how to google it and find it. Suppose you're maintaining a large legacy system, which has a large collection of data (tens of GB) of various formats, including XML and two different internal configuration formats. Suppose further that there are abstract rules governing the values these files may or may not contain. EXAMPLE: File A defines the raw, mathematical data pertaining to the aerodynamics of a car for consumption of the physics component of the system. File B contains certain values from File A in an easily accessible, XML hierarchy for consumption of a different component of the system. There exists, therefore, an abstract rule (or constraint) such that the values from File B must match the values from File A. This is probably the simplest constraint that can be specified, but in practice, the constraints between files can become very complicated indeed. What is the best method for managing these constraints between files of arbitrary formats, short of migrating it over to an RDBMS (which simply isn't feasible for the foreseeable future)? Has this problem been solved already? To be more specific, I would expect the solution to at least produce notifications of violated constraints; the solution need not resolve the constraints. ============================== Sample file structures File A (JeepWrangler2011.emv): MODEL JeepWrangler2011 { EsotericMathValueX 11.1 EsotericMathValueY 22.2 EsotericMathValueZ 33.3 } File B (JeepWrangler2011.xml): <model name="JeepWrangler2011"> <!--These values must correspond File A's EsotericMathValues--> <modelExtent x="11.1" y="22.2" z="33.3"/> [...] </model>

• What should you include in a development approach document?

  - by Liggy

  I'm in the middle of co-producing a "development approach" document for off-shore resources as they ramp up onto our project. The most recent (similar) document our company has used is over 80 pages, and that does not include coding standards/conventions documents. My concern is that this document will not be consumable and will therefore fail. What should be in a development approach document? Are there any decent guidelines on this topic? EDIT: The development approach document should detail the practices and techniques that will be used by software developers while software is designed, built, and tested.

• Is there such a thing as having too many private functions/methods?

  - by shovonr

  I understand the importance of well documented code. But I also understand the importance of self-documenting code. The easier it is to visually read a particular function, the faster we can move on during software maintenance. With that said, I like to separate big functions into other smaller ones. But I do so to a point where a class can have upwards of five of them just to serve one public method. Now multiply five private methods by five public ones, and you get around twenty-five hidden methods that are probably going to be called only once by those public ones. Sure, it's now easier to read those public methods, but I can't help but think that having too many functions is bad practice.

• The SQL Server Setup Portal

  - by BuckWoody

  One of the tasks that takes a long time for the data professional is setting up SQL Server. No, it isn’t that difficult to slide a DVD in a drive and click “Setup” but the overall process of planning the hardware and software environment, making decisions for high-availability, security and dozens of other choices can make the process more difficult. And then, of course, there are the inevitable issues that arise. Microsoft supports literally hundreds and even thousands of combinations of hardware and software drivers from vendors you’ve never even heard of. Making all of that work together is a small miracle, so things are bound to arise that you need to deal with. So, to help you out, we’ve designed a new “SQL Server Setup Portal”. It’s a one-stop-shop for everything you need to know about planning and setting up SQL Server. As time goes on you’ll see even more content added. There are already whitepapers, videos, and multiple places to search on everything from topic names to error codes. So go check it out – and if you have to do a lot of SQL Server Setups – and especially if you don’t – bookmark it as a favorite!

• What should I aware of , when preparing a document of website for later maintenance use?

  - by user782104

  The development team has finished a website and my duty is to prepare a document so that other programmer can maintain the website with ease . As I am inexperience of that, I would like to ask what should be mentioned (document structure) in that report? So far my idea is only prepare a ERD diagarm for database and flow chart for each function. Any other suggestions, eg. what cookies stored ? Thanks

• Sources of requirements? [closed]

  - by user970696

  I was reading a book about SW engineering the other day and it went like: Sources of both functional and non-functional requirements are: law (for specific cases) business and user requirements etc. //what else then? So the question is, what other sources of requirements there are when an analyst is gathering the information? Lets consider a desktop app for mobile operator. As for the comment, I do not think this is a broad question as the books usually mention 1-2 sources. I would like to know more, if anyone can help.

• What grammatical tense should I write my specifications in?

  - by John

  We are currently writing functional and technical specifications in a two column format; summary sentence and technical detail. The details often refer to an appendix with diagrams, layout designs ect. However I am struggling with what tense to write it in: With past tense as if the work is done I struggle to show highlight extensions of exiting work. Future tense as in it needs to do X starts to sound like a to do list or Tense neutral very hard as it has either going to be done or is done. To add further confusion this specification may be read by people who do not have English as a first language.

• What is an “implementation plan”?

  - by Abe Miessler

  I was recently given the task of creating an implementation plan document. When I asked for an example of one that I could look at, I was told to look at the Project Plan that had already been created an use that as a base. I'm still a bit confused on what I should be creating. Can anyone point me to a good example out there or to something that explains what this is and more importantly the details about what it should contain.

• Whats steps can I suggest to achieve the best Geolocation Result [migrated]

  - by Matt

  We are using Geolocation (getCurrentPosition()) in a website to determine a users position when using our site from a mobile device. I want to write an article explaining how the user can obtain the best results. Am I correct in assuming: Enabling GPS will yield the best result when in rural areas (less buildings to obscure line of sight to the satelites) Enabling Wi-Fi will yield the best results when in urban areas (generally more Wi-Fi hotspots available) Is it true that Android phones have better results from silently harvesting Wi-Fi hotspot details? Any links to reference material on this are appreciated

• Why not XHTML5?

  - by eegg

  So, HTML5 is the Big Step Forward, I'm told. The last step forward we took that I'm aware of was the introduction of XHTML. The advantages were obvious: simplicity, strictness, the ability to use standard XML parsers and generators to work with web pages, and so on. How strange and frustrating, then, that HTML5 rolls all that back: once again we're working with a non-standard syntax; once again, we have to deal with historical baggage and parsing complexity; once again we can't use our standard XML libraries, parsers, generators, or transformers; and all the advantages introduced by XML (extensibility, namespaces, standardization, and so on), that the W3C spent a decade pushing for good reasons, are lost. Fine, we have XHTML5, but it seems like it has not gained popularity like the HTML5 encoding has. See this SO question, for example. Even the HTML5 specification says that HTML5, not XHTML5, "is the format suggested for most authors." Do I have my facts wrong? Otherwise, why am I the only one that feels this way? Why are people choosing HTML5 over XHTML5?

• In what stage of development should comments be written?

  - by CurtisHx

  I'm a student working an internship at a larger company, writing small business apps in C#. I've noticed that I don't comment my code as I write it. Rather, I comment my code when I'm in the debugging stage of development. As I'm tracking down bugs, I'll run across a block that makes me think "hmm...that might confuse someone in the future. I'd better comment that", and I'll add the appropriate comments. All of my comments are done this way. Is this an appropriate way of commenting? Should comments be written as the code is written? Or does it really matter when the comments are written, as long as they adequately explain why this block is used?

• Installing nVidia drivers for Quadro FX 880M on 10.10 caused shutdown/startup issues.

  - by Chantz

  So I was facing weird graphics drivers issues due to the default nouveau drivers that came installed with Ubuntu 10.10 hence I installed the latest nVidia graphics drivers & I the weird graphics issues stopped happening. So far so good, but when I tried to shut down the laptop it got stuck at the window with text 15, shutting down... modem-manager: Caught signal 15, shutting down... init: Disconnected from system us init: dbus main process (1107) killed by TERM signal And this happens .everytime.without.fail. I tried updating the kernel and any/all drivers through update manager but it stil happens. Not only this even the startup screen is totally screwed up. It just displays Ubuntu 10.10 in text with 3 dots. But that is acceptable. To power cycle down the laptop each and everytime for shutdown is not cool. Same goes for when I try to restart. Interesting thing is if I try to shutdown the laptop when I am on the login screen it does so without any problems. I googled & many people seem to face the same issue but I couldn't find any silver bullet hoping to find one here.

• What norms/standards should I follow when writing a functional spec?

  - by user970696

  I would like to know what documents (ISO?) should I follow when I write a functional specification. Or what should designers follow when creating the system design? I was told that there was a progress in last years but was not told what the progress was in (college professor). Thank you EDIT: I do not speak about document content etc. but about standards for capturing requirements, for business analysis.

• Writing better timesheet

  - by gunbuster363

  Recently, my company started to require us to fill out a monthly timesheet, writing down everything you do in office. A timesheet contain 29-31 days, depends on the number of days of the month. I need to write the things I did in every row of the excel file, which represent a day. This timesheet embarrasses me, because something like this can happen: I spent Monday writing a program, and the program was done. Because my boss didn't give me other program to write, basically I am just sitting there and pretending I am busy in the following days before my boss gives me another assignment. Of course I should not write it in the timesheet as it is. I can write it in the timesheet that I write the program using 4 days, but it makes me feel very inefficient. I can separate the process into 1) write the program, 2)deploy the program, 3)test the program, but that can make the process so long like 3 weeks, really. Have you encountered such a situation? How would you deal with this? EDIT: some people said I should be more proactive about asking for more assignments, but here is the situation: the boss of my boss gives some jobs to my boss, then my boss gives the jobs to me, sometimes I can also see my boss being quite less busy. One of my colleagues said that I should not ask for another assignment in a proactive manner, because it would be a headache for my boss to think a job out of nowhere for me. I don't want the things turn out like that, really.

• Is a functional spec a part of the System requirement spec?

  - by user970696

  I wonder, sources like wikipedia or templates I found shows that Functional spec is a part of System requirement documents. I always thought that SRD is just overall decsription of the system, with all functional and non functional requirements. Yet I thought that Functional spec is more detailed and it is a separate document, while SRD is high level customer-created description (how is this one called then?) Could anyone help to make this clear for me?

• Patterns and conventions to document changes while developing

  - by Talysson

  Let's say I'm developing a second version of an API, and there's some changes in method names and so on from the previous version. What's a good way to document these changes ? I mean, is it better to document while changing (but, maybe, there will be more changes before the release, so I think it could be more work than necessary) or write down some topic and document after all the changes are done ?

• Information system using JQuery [on hold]

  - by user105300

  I would like to develop an information system for a school which will provide a single integrated source of information about any student who studies there. A full student profile will be built up year-by-year, as each student progresses through a degree program from their first point of contact with the university. Which type of JQuery should I use ? Which aspect or feature of it would be useful ? Also, which layer of the three-tier architecture does JQuery belong to ? It would be great if you could help me. Thank you.

• UnmarshalException: unexpected element

  - by Tom Brito

  I'm working with JAXB, and I'm having trouble to unmarshall a file; The following lines, on the beginning of the file, are causing trouble: <!DOCTYPE package PUBLIC "+//ISBN 0-9673008-1-9//DTD OEB 1.2 Package//EN" "http://openebook.org/dtds/oeb-1.2/oebpkg12.dtd"> <package xmlns="http://openebook.org/namespaces/oeb-package/1.0/" unique-identifier="uid"> If I delete all the !DOCTYPE it gives no Exception, but it doesn't load any value either.

• How do I edit an XML file with Perl?

  - by thebourneid

  I have a movie collection catalogue with local links to folders and files for an easy access. Recently I reorganaized my entire hard disk space and I need to update the links and I'm trying to do that automatically with Perl. I can export the data in a XML file and import it again. I can extract the new filepaths with the use of File::Find but I'm stuck with two problems. I have no idea how to connect the $title from the new filepath with the corresponding $title from the XML file. I'm dealing with such files for the first time and I don't know how to proceed with the replacement process. Here is what I've done till now use strict; use warnings; use File::Basename; use File::Find; use File::Spec; use XML::Simple; use Data::Dumper; my $dir_target = 'D:/Movies/'; my %titles_locations = (); find(\&file_handler, $dir_target); sub file_handler { /\.iso$/ or return; my $fn = $File::Find::name; $fn =~ s/\//\\/g; $fn =~ /(.*\\)(.*)/; my $path = $1; my $filename = $2; my $title = (File::Spec->splitdir($fn))[2]; $title =~ s/(.*?)\s\(\d+\)$/$1/; $title =~ s/~/:/; $title =~ s/`/?/; my $link_local = '<link><description>Folder</description><url>'.$path.'</url><urltype>Movie</urltype></link><link><description>'.$filename.'</description><url>'.$fn.'</url><urltype>Movie</urltype></link>' unless $title eq ''; $titles_locations{$title} = {'filename'=>$filename, 'path'=>$path }; } my $xml_in = XMLin('somepath/test.xml', ForceArray => 1, KeepRoot => 1); my $title = {'key1' => 'title', 'key2' => 'links'}; foreach my $link (keys %$title) { } print Data::Dumper->Dump([$title]); my $xml_out = XMLout($xml_in, OutputFile => 'somepath/test_out.xml', KeepRoot=>1); And here is a snippet of the data I need to edit. If found imdb and dvdempire link - do not touch. if found local links replace, otherwise insert. I'm willing to complete the code myself but need some directions how to proceed further. Thanks. <title>$title</title> ....... <links> <link> <description>IMDB</description> <url>http://www.imdb.com/title/VARIABLE</url> <urltype>URL</urltype> </link> <link> <description>DVD Empire</description> <url>http://www.dvdempire.com/VARIABLE</url> <urltype>URL</urltype> </link> <link> <description>Folder</description> <url>OLD_FOLDERPATH</url> <urltype>Movie</urltype> </link> <link> <description>OLD_FILENAME</description> <url>OLD_FILENAMEPATH</url> <urltype>Movie</urltype> </link> </links>

• Doing XML extracts with XSLT without having to read the whole DOM tree into memory?

  - by Thorbjørn Ravn Andersen

  I have a situation where I want to extract some information from some very large but regular XML files (just had to do it with a 500 Mb file), and where XSLT would be perfect. Unfortunately those XSLT implementations I am aware of (except the most expensive version of Saxon) does not support only having the necessary part of the DOM read in but reads in the whole tree. This cause the computer to swap to death. The XPath in question is //m/e[contains(.,'foobar') so it is essentially just a grep. Is there an XSLT implementation which can do this? Or an XSLT implementation which given suitable "advice" can do this trick of pruning away the parts in memory which will not be needed again? I'd prefer a Java implementation but both Windows and Linux are viable native platforms. EDIT: The input XML looks like: <log> <!-- Fri Jun 26 12:09:27 CEST 2009 --> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Registering Catalina:type=Manager,path=/axsWHSweb-20090626,host=localhost</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Force random number initialization starting</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Getting message digest component for algorithm MD5</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>Completed getting message digest component</m></e> <e h='12:09:27,284' l='org.apache.catalina.session.ManagerBase' z='1246010967284' t='ContainerBackgroundProcessor[StandardEngine[Catalina]]' v='10000'> <m>getDigest() 0</m></e> ...... </log> Essentialy I want to select some m-nodes (and I know the XPath is wrong for that, it was just a quick hack), but maintain the XML layout. EDIT: It appears that STX may be what I am looking for (I can live with another transformation language), and that Joost is an implementation hereof. Any experiences? EDIT: I found that Saxon 6.5.4 with -Xmx1500m could load my XML, so this allowed me to use my XPaths right now. This is just a lucky stroke so I'd still like to solve this generically - this means scriptable which in turn means no handcrafted Java filtering first. EDIT: Oh, by the way. This is a log file very similar to what is generated by the log4j XMLLayout. The reason for XML is to be able to do exactly this, namely do queries on the log. This is the initial try, hence the simple question. Later I'd like to be able to ask more complex questions - therefore I'd like the query language to be able to handle the input file.

• VS 2010 SP1 BETA – App.config XML Transformation Fix

  - by João Angelo

  The current version for App.config XML tranformations as described in a previous post does not support the SP1 BETA version of Visual Studio. I did some quick tests and decided to provide a different version with a compatibility fix for those already experimenting with the beta release of the service pack. This is a quick workaround to the build errors I found when using the transformations in SP1 beta and is pretty much untested since I’ll wait for the final release of the service pack to take a closer look to any possible problems. But for now, those that already installed SP1 beta can use the following transformations: VS 2010 SP1 BETA – App.config XML Transformation And those with the RTM release of Visual Studio can continue to use the original version of the transformations available from: VS 2010 RTM – App.config XML Transformation
