• What program do you use to write technical documentation?

  - by Tatu Ulmanen

  I'm writing an architecture/technical documentation for an inhouse project and I'm becoming more and more frustrated with Microsoft Word as I seem to use most of my time getting things to align correctly. Word has horrible usability issues but I didn't come here to rant, rather I'd like to know whether there exists something more suitable for the job. The point of this documentation is to provide a "big picture" of the system, and as such I'm not generating documentation from source code but rather writing it all by hand. Are there any alternatives to Microsoft Word for writing properly formatted technical documentation with less frustration?

• Lesser-known Github features that I'm missing out on with Bitbucket? [closed]

  - by Ghopper21

  I've been using Bitbucket for my small-team development projects, with the assumption that it is more-or-less a Github clone with pricing that is better for my situation and support for Mercurial (which I don't need). However, I'm seeing there are material-if-not-overwhelming differences, e.g. Github's appealing and useful branches page versus Bitbucket's overly simple branch drop-down list. This makes me wonder: what else am I missing out on? What are the lesser known Github features that folks like me using Bitbucket to save money are missing out on? EDIT: following closure, I've asked for advice on making this question productive over at meta. See here.

• Re-sizing the form without scaling the GUI

  - by Bmoore

  I am writing a turn based strategy game in C#. My GUI implementation consists of class that extends Form containing a class that extends Panel. When I render the GUI I draw to the paint method in the panel. I am trying to figure out what is the best way for handling form re-size events. I know I want a minimum window size, but I would prefer to not have a maximum or a set size. Ideally the GUI would reveal more/less of the map as the user changes the window size. I would like to avoid scaling the graphics if at all possible. What is the best way to handle re-size events?

• When designing a job queue, what should determine the scope of a job?

  - by Stuart Pegg

  We've got a job queue system that'll cheerfully process any kind of job given to it. We intend to use it to process jobs that each contain 2 tasks: Job (Pass information from one server to another) Fetch task (get the data, slowly) Send task (send the data, comparatively quickly) The difficulty we're having is that we don't know whether to break the tasks into separate jobs, or process the job in one go. Are there any best practices or useful references on this subject? Is there some obvious benefit to a method that we're missing? So far we can see these benefits for each method: Split Job lease length reflects job length: Rather than total of two Finer granularity on recovery: If we lose outgoing connectivity we can tell them all to retry The starting state of the second task is saved to job history: Helps with debugging (although similar logging could be added in single task method) Single Single job to be scheduled: Less processing overhead Data not stale on recovery: If the outgoing downtime is quite long, the pending Send jobs could be outdated

• Project OpenPTK Release 2.1 Available

  - by Scott Fehrman

  The OpenPTK owners are pleased to announce that release 2.1 is available.  It has been "tagged" in the svn repository. See the download page for details.   This release is an update to version 2.0.  This release contains bug fixes, enhancements to existing capabilities, and new features.  The most notable change in this release is the use of maven, instead of ant, for the build process.  The adoption of maven has made the project more modular, reduced its download size (less bundled jar files) and will enable the future support of Project OpenPTK in a maven repository. For full details, see the OpenPTK version 2.1 Release Notes

• creating a list of consecutive integers in c#

  - by Alex Bransky

  If there's already a way to get a List<int> of consecutive integers without a loop in C#, I don't know what it is, so I created a method for it.         public static List<int> GetIntegerListFromRange(int start, int end) {             if (end < start) {                 throw new ArgumentException("Faulty parameter(s) passed: lower bound cannot be less than upper bound.");                }             List<int> returnList = new List<int>(end - start + 1);             for(int i = start; i <= end; i++) {                 returnList.Add(i);             }             return returnList;         }

• Have you worked with a well designed application?

  - by Vilx-

  Inspired by this question, I started wondering - is there or has there ever been such a thing as a "well designed application"? One where the architecture would be perfect and no refactoring would ever be needed; code would be easy to read and understand even for someone new to the project; changes could be done with a 100% certainty that they won't break anything; etc? I must admit that whatever codebases I've worked with, they've all been more or less a mess. Even code that I start myself only stays organized at the start, and then slowly deteriorates as the time passes. I'm even starting to accept this as part of life and can't figure out whether I should be worried about that or not. So... is there such a thing as a "well designed application"? Or is all our code so shitty that there isn't even a point in trying to make it better, because it will never be good anyway?

• Is there a correlation between complexity and reachability?

  - by Saladin Akara

  I've been studying cyclomatic complexity (McCabe) and reachability of software at uni recently. Today my lecturer said that there's no correlation between the two metrics, but is this really the case? I'd think there would definitely be some correlation, as less complex programs (from the scant few we've looked at) seem to have 'better' results in terms of reachability. Does anyone know of any attempt to look at the two metrics together, and if not, what would be a good place to find data on both complexity and reachability for a large(ish) number of programs? (As clarification, this isn't a homework question. Also, if I've put this in the wrong place, let me know.)

• Is the tap-to-click issue solved

  - by AWE

  I'm just an average Joe when it comes to computing (maybe less then the average Joe) but I hate tap-to-click. In system and settings there is no touchpad tab? Is it true that this has been fixed? I'm using Dell inspiron N5110 xinput list: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PS/2 Generic Mouse id=13 [slave pointer (2)] This is really strange because Dell is one of the top manufacturers in laptops and Ubuntu one of the top distros in Linux and Canonical claims that they are working closely with Dell.

• How can I compile an IP address to country lookup database to make available for free?

  - by Nick

  How would I go about compiling an accurate database of IP addresses and their related countries to make available as an open source download for any web developer who wants to perform a geographic IP lookup? It seems that a company called MaxMind has a monopoly on geographic IP data, because most online tutorials I've seen for country lookups based on IP addresses start by suggesting a subscription to MaxMind's paid service (or their less accurate free 'Lite' version). I'm not completely averse to paying for their solution or using the free one, but the concept of an accurate open source equivalent that anyone can use without restriction appeals to me, and I think it would be useful for the web development community. How is geographic IP data collected, and how realistic is it to hope to maintain an up-to-date open version?

• Dolphin search bar missing. How can i get it back?

  - by Ike

  A while ago, my search bar went missing in dolphin. If the search toolbar is checked for view/unhide, nothing shows up. I noticed if i check and uncheck the button to hide/unhide it, a small, thin content-less bar slightly pushes the rest of the toolbar up. i tried reconfiguring with dpkg, purging and reinstalling, etc. i left it alone as i thought it would be fixed in an update, but today i upgraded daolphin and it's still gone. any thoughts?

• Fiddler - A useful free tool for checking Web Services (and web site) traffic

  - by TATWORTH

  Recently I had reason to be very glad that I had Fiddler. I was able to record some web service traffic and identify a problem as Fiddler can record both the call to a web service and response from the web service. By seeing the actual data traffic I was able to resolve a problem found in testing in less time than it has taken me to write this blog entry! This tool is also useful for studying general web site traffic. Fiddler is available from http://www.fiddler2.com/fiddler2/ There are training videos available on the above site.

• How do you describe your profession in a public place or conference?

  - by Jenko

  I've often been in situations where non-technical people ask me, "So, what do you do?" ... and I've found it somewhat hard to describe that I spend the entirely of my days pouring over colored text. Of course, its quite reasonable to say "I design software" or "I develop computer applications", but that still feels somewhat "lame" and generic. So how do you describe your profession in public situations? are there any insights for those of us less gifted in public speaking?

• How often do CPUs make calculation errors?

  - by veryfoolish

  In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

• Why is the superblock last mount time in the future?

  - by user69541

  Future time: Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set." FIXED. According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance: mjh@mjh-desktop:~$ sudo service ntp start [sudo] password for mjh: ntp: unrecognized service mjh@mjh-desktop:~$ mjh@mjh-desktop:~$ sudo apt-get install update Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package update mjh@mjh-desktop:~$ sudo service ntp start ntp: unrecognized service mjh@mjh-desktop:~$ Suggestions?

• Is programming as a profession in a race to the bottom?

  - by q303

  It seems to me that the programming industry is in a race to the bottom. If we take the practices of: Not taking time to implement best practices Using other's people code as much as possible (custom code as a liability) Using increasingly higher level languages to improve productivity GUI based development "tools" that greatly simplify "programming" and do not require people to understand the plumbing behind the code These things imply to me that we are in a race to becoming like any other office worker. It is in the employer's interest for things to not require skill (easier to replace), for things to be prebuilt (less project time). My point here is that a) is there a misalignment between skill and the economic interests of the employer? and b) if there is, how do you mitigate it to enforce professional standards?

• Is there a word or description for this type of query?

  - by Nick

  We have the requirement to find a result in a collection of records based on a prioritised set of search criteria against a relational db (I'm talking indexed field matching here rather than text search). The way we are thinking about designing the query is to begin with a highly refined and specific set of criteria. If there are no results for this initial query we want to progressively reduce the criteria one by one in order of reducing priority, querying each time such a less specific set of criteria until we find a result we can accept. Alternatively, we have considered starting with a smaller set of criteria and increasing until we have reduced number of results down to the last set. What I would like to know is if an existing term to describe this type of query exists? So that we can look to model our own on existing patterns and use best practice.

• Is ROA a specific form of doing SOA?

  - by JohnDoDo

  I have read somewhere that ROA (Resource Oriented Architecture) is SOA (Service Oriented Architecture) with specific constraints added. SOA is the abstract concept of combining discrete pieces of software and ROA is an implementation of SOA with all of the constraints of RESTful services applied to it: SOA = the concept ROA = the concept + specific implementation details I also had my share of posts saying that ROA is different than SOA, then simply fallback to statements like "ROA is REST" and "SOA is SOAP" and presenting the same more or less pertinent comparisons and differences between SOAP and REST. So just to clear up my confusion: Is ROA a specific form of doing SOA?

• Is it possible that Unity would some day switch back to Mutter?

  - by David

  I remembered that the first Unity was indeed built on Mutter, but later ported to Compiz due to poor performance. I also know Canonical practically incorporated Compiz to work closely for future Unity, so this is getting less likely. But Compiz just seems pretty outdated now that GNOME3/GTK3/Mutter is becoming more mainstreamed, and it is known to deliver some performance issue, but on the other hand Mutter seems pretty good and is still steadily developing now, I'm just wondering if anyone related to the project is still testing and evaluating the possibility of Unity on Mutter? Not that you have to tell me now if you're going to do it or not. I just wanna know if anyone is considering it. Thanks.

• New Development Snapshot

  I finally did the work necessary to improve the codegen for finally handlers. More improvements are still possible, but at least most finally handlers will now execute without touching the exception object (and hence without having to do any mapping/stack trace collection work). It also means that assembly file sizes are a little bit smaller and that the debugging experience should be improved (less exception catching & rethrowing). Changes: ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• LINQ/LAMBDA filter query by date [on hold]

  - by inquisitive_one

  I'm trying to use LINQ to SQL to retrieve earnings data for a particular date range. Currently the table is set up as follows: Comp Eps Year Quarter IBM .5 2012 2 IBM .65 2012 3 IBM .60 2012 4 IBM .5 2011 2 IBM .7 2013 1 IBM .8 2013 2 Except for Eps, all fields have a data type of string or char. Eps has a data type of double. Here's my code: var myData = myTable .Where(t => t.Comp.Equals("IBM") && Convert.Int32(string.Format("{0}{1}", t.Year, t.Quarter)) <= 20131); I get the following error when I tried that code: Method 'System.String Format(System.String, System.Object, System.Object)' has no supported translation to SQL How can I select all Eps that has a year & quarter less than "20132" using a lambda expression?

• Is the phrase "never reinvent the wheel" suitable for students?

  - by Gnijuohz

  I find myself constantly running into this expression "don't reinvent the wheel" or "never reinvent the wheel" when I ask some questions on SO. They tell you to use some frameworks or existing packages. I know where this attitude is coming from since it's unwise to waste time on something others have already solved. Or it that so? As a student, I find by using some code others wrote to solve my problem I can't learn as much as I'd like to, and I gain less insight. And sometimes I think that phrase is mainly for working programmers facing deadlines and not for students like me. Is it that bad to "reinvent the wheel"? Maybe I'm thinking it wrong? Maybe there is a way I can avoid reinventing the wheel and at the same time learn a lot?

• How to read data from a large number of files in a folder? [closed]

  - by Gary Dhillon

  I seem to be having some trouble figuring out a solution for a problem. See the thing is, my code is supposed to read a lot of data from a bunch of files. I've been thinking of two different approaches: 1) the first one seems simpler, I ask the user if they would like to examine the next file or just quit out of the program.( I believe this is simpler and would take less time to run through.) 2)It reads through all the files and outputs the results for each of them, and then a shared result for all of them.( I think this would be better for what I've been asked to do and it saves the user some hassle.) If anyone can tell me how to code either of these in C++, I would be very grateful. Here is a sample of the file: 0 -- 19 weight 0 -- 20 weight I use this to determine density and possibly ignore the weights which is a number.

• Depending on another open source library: copy/paste code or include

  - by user5794

  I'm working on a large class and started implementing new features that need graphics. I started writing the graphics functions myself, but I know that open source libraries exist that can provide me with this functionality without me having to write it myself. The problem is that I prefer the class to be self-sufficient and not dependent on any other library. If I don't write it myself, I would have to ask the user to make sure a graphics library is already installed (less user-friendly). If I write it myself, I do a lot more work than I have to. I could also copy/paste some of the relevant code into my own class, but not sure about the disadvantages of doing this (it's an open source library that matches my license, so I'm not concerned with legality, just programming-wise if there are disadvantages). So what should I do: copy paste code from the external library write the code myself so it's truly self-sufficient ask the user to download and install another library

• Facebook connect vs. OpenID

  - by digit1001

  I just started working on a new project that has a general login feature. One suggestion in a meeting was to look into Facebook Connect or OpenID as an alternative. I'm curious if there's one that has less of a learning curve, or if they can both be used on the same site. Also, when you use either, do you have them initially create the account and just get a verify True/False back that you then use to set up a local user account? I what about forgotten passwords? I'm kind of curious as to best practices for integrated this type of login with a "traditional" one where you store the user info yourself. Thanks, D
