  • bug: deviation from requirements vs deviation from expectations

    - by user970696
    I am not clear on this one. No matter the terminology, in the end the software fault/bug causes (according to a lot of sources): Deviation from requirements Devation from expectations But if the expectations are not in requirements, then stakeholder could see a bug everywhere as he expected it to be like this or that..So how can I really know? I did read that specification can miss things and then of course its expected but not specified (by mistake).

  • Java(standard, non standard) or Non Java based Web developement [closed]

    - by LivingThing
    I am new to web development. Initially i thought i would be learning LAMP or WAMP to acquire web developement skills but recently i came across Standard Java based (JSP, servlets) and Non standard Java based (GWT). My question is related to if and how LAMP can be compared with Java (standarad or non stadard) technologies. Is LAMP even comparable to Java based tech or it does something else or something more or less ? what requirement for a web developement projects require the choice that which of these 'technologies' should be choosen ? Thank YOu

  • Adding Windows 2008 R2 Standard 64 bit DC to Windows 2008 Standard 32 bit Domain

    - by user137652
    All of our domain controllers (2) are Windows 2008 Standard 32 bit. We are trying to add a Standard 2008 R2 64 bit domain controller to the forest but for some reason during DCPROMO, we receive the following error: "to install a domain controller into this active directory forest,you must first prepare the forest using "adprep/forestprep" etc We went ahead an ran adprep /forestprep on our established domain controller and allowed time to replicate. When attempting to execute dcpromo again, we receive the same error. What gives?

  • Why is the "Standard Account" option disabled (grayed-out)

    - by Clayton Hughes
    I just installed Win7 64bit on a new hard drive, and I created a user account through the OOBE. I want to make my user account a standard user. However, if I go into "User Accounts" and select "Change my account type", the standard user option is greyed out--this account apparently has to be an administrator. I thought maybe it was the only admin account on the machine, so I tried to create a new user account named "Administrator", but was told I couldn't, because one already exists. What gives? What do I have to do to run as a standard user?

  • Libraries for developing NCPDP SCRIPT based systems (a standard for e-prescribing)

    - by Kaveh Shahbazian
    What are (based on experiences) best (commercial or open source) libraries for developing NCPDP-based systems? Background: NCPDP (National Council for Prescription Drug Programs) is a not-for-profit, ANSI-accredited, standards development organization. One of it's standards is the SCRIPT Standard for Electronic Prescribing, which allows PHARMACY, PRESCRIBER (i.e. Physician) and PAYERS (patient or more often insurer) communicate. So the SCRIPT standard is about data transmission. Problem: One step in implementing such systems is to develop models for data based on SCRIPT standard. These models should have utilities for serializing/deserializing to/from SCRIPT binary format and SCRIPT XML format (there are two distinct formats here; both must be supported). Here rises the problem (for me at least). To develop this subsystem for handling the model, implementing serializing and deserializing facilities and keep it uptodate with the SCRIPT standard specifications is a lot of work; it needs it's own team and team management issues (to support a standard implementation). So I am looking for a solution to this problem; to keep standard implementation out of the way and focusing on main problems. Thanks to all (Thankyou Freiheit for your hints!) Edit 2: Thanks to all for help! NCPDP (National Council for Prescription Drug Programs) is an standard for e-prescribing. It defines two formats for message transmission: binary and XML. Implementing XML is somehow easier because it is a standard format which in turn gives us more tooling options. The binary format has a very big specification and time-consuming to implement. I did not find an open source solution to work with. So I am looking for commercial alternatives. Edit 1: Please guide me; what's wrong with this question?

  • Change environment variables as standard user (Windows 7)

    - by SealedSun
    When clicking on "Advanced system settings", I need to login as the administrator and hence only edit the administrators environment variables (in addition to the machine wide ones). How do I edit the environment variables of a standard user? Details With the migration to Windows 7, I decided to work as a standard user instead of an unprivileged administrator. Works well so far but I encountered a tiny problem: When I try to change per user environment variables via the control panel I have to login as an administrator. But since I run that part of the control panel as the administrator I can only edit the administrators variables. How am I supposed to edit my own environment variables? Without resorting to extreme measures, such as editing the registry (as suggested in "Is there any command line tool that can be used to edit environment variables in Windows?" )

  • standard deviation on excel

    - by user270692
    so I have 3 data sets, which all came from the first data set using the excel program. all consisted of random numbers from =randbetween(0,100) starting from A2:A102 which is 100 integers. for data set b I had to enter=SUM(A2+5) press enter and drag it down to get the integers for cells B2:B102 and for C I had to do multiplication t get it. I did =PRODUCT(A2:A102*5). so everything was taken from data set A. now I did the formulas needed to do sample standard dev and mean(average) . for data set a and b the standard deviations were the same but the mean was larger in data set B of course because I added 5 to each cell in set A. my question is why wouldn't the standard deviation be the same for data set C also? if im using the info from data set A? and how do I calculate the standard deviation (sample) by hand so I can explain why the standard dev doesn't change but the mean does. I don't know what numbers to include in the formula for sample standard deviation.

  • What is the standard place for static library files on Unix/Ubuntu

    - by Max
    Hi, I am trying to install a library manually, well actually just put it in a sensible location preferably in my LIB path. I have a lib[...].a file and a bunch of headers pertaining to that static library file. If I look under /usr/lib/ I see only .so files, likewise for /lib/, /lib32/ etc. I figure I could chuck it in there, but is there any place where it can get cozy with other .a files or is that as good place as any? I'm not an library expert, but I'm pretty sure it won't matter functionally, but I'd like to learn conventional best practice. Also, where is the standard place to put the headers? Thanks!

  • The C++ Standard: Book Recommendation.

    - by Nawaz
    I'm planning to buy this book: The C++ Standard: Incorporating Technical Corrigendum No. 1 http://www.flipkart.com/standard-british-standards-institution-incorporating-book-0470846747 Since it's cost is too much for me (being an Indian we've the habit of buying only low-price edition books :D), I want to make sure if this is the correct edition/version of the Standard. So I need some good advice if I should go for it, or there is better option for me which I'm unaware of. PS: I want to buy hard copy, not PDF.

  • Force import module from Python standard library instead of PYTHONPATH default

    - by jrdioko
    I have a custom module in one of the directories in my PYTHONPATH with the same name as one of the standard library modules, so that when I import module_name, that module gets loaded. If I want to use the original standard library module, is there any way to force Python to import from the standard library rather than from the PYTHONPATH directory, short of renaming the custom module and changing every reference to point to the new name?

  • Calculating moving average/stdev in SAS?

    - by John
    Hye guys, I included a screenshot to help clarify my problem: http://i40.tinypic.com/mcrnmv.jpg. I'm trying to calculate some kind of moving average and moving standard deviation. The thing is I want to calculate the coefficients of variation (stdev/avg) for the actual value. Normally this is done by calculating the stdev and avg for the past 5 years. However sometimes there will be observations in my database for which I do not have the information of the past 5 years (maybe only 3, 2 etc). That's why i want a code that will calculate the avg and stdev even if there is no information for the whole 5 years. Also, as you see in the observations, sometimes I have information over more than 5 years, when this is the case I need some kind of moving average which allows me to calculate the avg and stdev for the past 5 year. So if a company has information for 7 years I need some kind of code that will calculate the avg and stdev for, lets say, 1997 (by 1991-1996), 1998 (by 1992-1997) and 1999 (1993-1998). As i'm not very familiar with sas commands it should look (very very roughly) like: set var if year = i then stdev=stdev(year(i-6) untill year(i-1)) and average = avg(year(i-6) untill year(i-1)) Or something like this, I really have no clue, I'm gonna try and figure it out but it's worth posting it if I won't find it myself. Thanks!

  • Does Objective-C have a Standard Library?

    - by Roman A. Taycher
    Most somewhat modern programming languages have a standard library? It is my impression is that there isn't a decent sized standard library for Obj-C , rather that it relies mostly/all on Cocoa and that (plus people not wanting to use GNUstep) is why Obj-C is only used on macs)? Is this true/to what extent? Are there any standard obj-c collections? (note I haven't done any Obj-C programming and am not to likely to try it in the near future, I'm just curious). P.S. are there a any decent non-Cocoa/Gnustep Libraries? are they non-apple, are they open source, well documented?

  • How and when is something considered industry standard?

    - by Sonny Boy
    Hey all, I'm currently working on a proposal for my organization which includes a shift from waterfall development methodology over to a Scrum framework. As I work for a university, citations for all of my work is extremely important. As I was looking to add a citation for my statement of Agile being the industry standard, I kind of hit a wall. Who is it that decides when something become industry standard and how is that decision made?

  • Most useful Python modules from the standard library?

    - by EOL
    I am teaching a graduate level Python class at the University of Paris, and the students need to be introduced to the standard library. I want to discuss with them about some of the most important standard modules. What modules do you think are absolute musts? Even though responses probably vary depending on your field (web programming, science, etc.), I feel that some modules are commonly needed: math, sys, re, os, os.path, logging,… and maybe: collections, struct,… What modules would you suggest I present, in a 1 or 2 hour slot?

  • How do the size standard libraries compare for different languages

    - by Roman A. Taycher
    Someone was recently raving about how great jQuery was and how it made javascript into a pleasure and also how the whole source code was so small(and one file). I looked it up on www.ohloh.net/ and it said it was about 30,000 lines of javascript, when I tired curl piped to wc it said about 5000 lines(strange discrepancy that, maybe test suites, ect?). I thought well it isn't that strange since javascript from what I've heard has a lot of fun dynamic tricks, so you can probably get away with a small library. But then I thought what about other high level languages, the ones with large standard libraries and wondered how big the standard are for python/ruby/haskell/pharo(smalltalk)/*ml/ect. (libraries not vm stuff to the degree its possible to separate it) Anybody know? Any details (comment/blank/code lines , test code lines, lines in language vs lines in ffi/byte-code) are appreciated! edit: ps. since it started this me asking about jQuery as a bonus if you could please list the size of mega frameworks, a megaframewok provides so much that people using an x megaframework in language y might sometimes refer to programming in xy or even x rather then in y (ie. : qt, jQuery, etc.).

  • Is a coding standard even needed any more?

    - by SomeKittens
    I know that it's been proven that a coding standard helps enormously. However, there are many different tools and IDEs that will format to whatever standard the programmer prefers. So long as the code's neat/commented (and not a spaghetti mess), I don't see the need for a coding standard. Are there any arguments for the development of a coding standard (we don't have one, but I was looking into creating one)?

  • 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?

  • Alternative Python standard library reference

    - by Ender
    I love Python; I absolutely despise its official documentation. Tutorials do not count as library references, but that appears to be what they're attempting. What I really want is the ability to find a class in the standard library and view documentation for all of its properties and methods. Actionscript, MSDN, and Java all do this just fine (although each with their odd quirks). Where is this for python? For example, I wanted to sort a list. mylist.sort(). Awesome. But what if I wanted it sorted in descending order? Official documentation is not - much - help. Or what if I wanted to specify a key function? That's also supported: mylist.sort(key=lamba item: item.customVar)- but documented...where? I understand that Python's approach to OOP may not be equivalent to Java et. al. Maybe list isn't actually a class - maybe it's just a function that returns an iterable when the tachyon beams are set to glorious and the unboxed hyper enumeration is quantized, but...I don't care. I just want to know how to sort lists. (Apologies for the angst - too much caffeine today)

  • Where to find algorithms for standard math functions?

    - by dsimcha
    I'm looking to submit a patch to the D programming language standard library that will allow much of std.math to be evaluated at compile time using the compile-time function evaluation facilities of the language. Compile-time function evaluation has several limitations, the most important ones being: You can't use assembly language. You can't call C code or code for which the source is otherwise unavailable. Several std.math functions violate these and compile-time versions need to be written. Where can I get information on good algorithms for computing things such as logarithms, exponents, powers, and trig functions? I prefer just high level descriptions of algorithms to actual code, for two reasons: To avoid legal ambiguity and the need to make my code look "different enough" from the source to make sure I own the copyright. I want simple, portable algorithms. I don't care about micro-optimization as long as they're at least asymptotically efficient. Edit: D's compile time function evaluation model allows floating point results computed at compile time to differ from those computed at runtime anyhow, so I don't care if my compile-time algorithms don't give exactly the same result as the runtime version as long as they aren't less accurate to a practically significant extent.
