• SSH new connection begins to hang (not reject or terminate) after a day or so on Ubuntu 13.04 server

  - by kross

  Recently we upgraded the server from 12.04 LTS server to 13.04. All was well, including after a reboot. With all packages updated we began to see a strange issue, ssh works for a day or so (unclear on timing) then a later request for SSH hangs (cannot ctrl+c, nothing). It is up and serving webserver traffic etc. Port 22 is open (ips etc altered slightly for posting): nmap -T4 -A x.acme.com Starting Nmap 6.40 ( http://nmap.org ) at 2013-09-12 16:01 CDT Nmap scan report for x.acme.com (69.137.56.18) Host is up (0.026s latency). rDNS record for 69.137.56.18: c-69-137-56-18.hsd1.tn.provider.net Not shown: 998 filtered ports PORT STATE SERVICE VERSION 22/tcp open ssh OpenSSH 6.1p1 Debian 4 (protocol 2.0) | ssh-hostkey: 1024 54:d3:e3:38:44:f4:20:a4:e7:42:49:d0:a7:f1:3e:21 (DSA) | 2048 dc:21:77:3b:f4:4e:74:d0:87:33:14:40:04:68:33:a6 (RSA) |_256 45:69:10:79:5a:9f:0b:f0:66:15:39:87:b9:a1:37:f7 (ECDSA) 80/tcp open http Jetty 7.6.2.v20120308 | http-title: Log in as a Bamboo user - Atlassian Bamboo |_Requested resource was http://x.acme.com/userlogin!default.action;jsessionid=19v135zn8cl1tgso28fse4d50?os_destination=%2Fstart.action Service Info: OS: Linux; CPE: cpe:/o:linux:linux_kernel Service detection performed.

• What are the advantages of version control systems that version each file separately?

  - by Mike Daniels

  Over the past few years I have worked with several different version control systems. For me, one of the fundamental differences between them has been whether they version files individually (each file has its own separate version numbering and history) or the repository as a whole (a "commit" or version represents a snapshot of the whole repository). Some "per-file" version control systems: CVS ClearCase Visual SourceSafe Some "whole-repository" version control systems: SVN Git Mercurial In my experience, the per-file version control systems have only led to problems, and require much more configuration and maintenance to use correctly (for example, "config specs" in ClearCase). I've had many instances of a co-worker changing an unrelated file and breaking what would ideally be an isolated line of development. What are the advantages of these per-file version control systems? What problems do "whole-repository" version control systems have that per-file version control systems do not?

• Finding a problem in some task [closed]

  - by nagisa

  Recently I competed in nation wide programming contest finals. Not unexpectedly all problems were algorithmic. I lost (40 points out of 600. Winner got ~300). I know why I lost very well - I don't know how to find actual problem in those obfuscated tasks which are life-blood of every competition. I think that being self-taught and not well versed in algorithms got me too. As side effect of learning things myself I know how to search for information, however all I could find are couple questions about learning algorithms. For now I put Python Algorithms: Mastering Basic Algorithms in the Python Language and Analysis of Algorithms which I found in those questions to my "to read" list. That leaves my first problem of not knowing how to find a problem unsolved. Will that ability come with learning algorithms? Or does it need some special attention? Any suggestions are welcomed.

• How does dependecy injection increase coupling?

  - by B?????

  On the Wikipedia page on dependency injection, the disadvantages section tells us this: Dependency injection increases coupling by requiring the user of a subsystem to provide for the needs of that subsystem. with a link to an article against dependency injection. Dependency injection makes a class use the interface instead of the concrete implementation. That should result in decreased coupling, no? What am I missing? How is dependency injection increasing coupling between classes?

• Writing algorithm on 2D data set in plain english

  - by Alexandre P. Levasseur

  I have started an introductory Java class and the material is absolutely horrendous and I have to get excellent grades to be accepted into the master's degree, hence my very beginner question: In my assignment I have to write algorithms (no pseudo-code yet) to solve a board game (Sudoku). Essentially, the notes say that an algorithm is specification of the input(s), the output(s) and the treatments applied to the input to get the output. My question lies on the wording of algorithms because I could probably code it but I can't seem to put it on paper in a coherent way. The game has a 9x9 board and one of the algorithms to write has to find the solution by looking at 3 squares (either horizontal or vertical) and see if one of the three sub-squares match the number you are looking for. If none match then the number you are looking to place is in one of the other 2 set of 3 sub-squares (see image to get a better idea). I really can't get my head around how to formulate the solution into the terms described above or maybe it's just too simple, here's what I was thinking: Input: A 2-dimensional set of data of size 9 by 9 to be solved and a number to search for. Ouput: A 2-dimensional set of data of size 9 by 9 either solved or partially solved. Treatment: Scan each set of 3x9 and 9x3 squares. For each line or column of a 3x3 square check if the number matches a line (or column). If it does then move to the next line (or column). If not then proceed to the next 3x3 square in the same line (or column). Rinse and repeat. Does that make sense as an algorithm written in plain english ? I'm not looking for an answer to the algorithm per se but rather on the formulation of algorithms in plain english.

• If you had to reinvent a new syntax for regular expressions, what would it look like?

  - by Timwi

  Regular expressions as they are today are pretty much as concise and compact as they can be. Consequently, they are often criticised for being unreadable and hard to debug. If you had to reinvent a new syntax for regular expressions, what would it look like? Do you prefer the concise syntax they already have (or a different but similarly concise syntax)? If so, please justify why you think regular expressions deserve to be this concise, but your favourite programming language doesn’t (unless it’s Perl). Or do you think regular expressions should have a slightly more spaced-out syntax and look a bit more like operators and syntax elements normally do in programming languages? If so, provide examples of what you think the syntax should look like, and justify why it is better than the current syntax. Or do you think there shouldn’t even be a special syntax for regular expressions, and instead they should be constructed from syntax elements already present in the programming language? If so, give examples of a syntax that might be used to construct such regular expressions.

• programming practices starting

  - by Tamim Ad Dari

  I have taken my major as computer science and Engineering and I am really confused at this moment. My first course was about learning C and C++ and I learned the basics of those. Now I am really confused what to do next. Some says I should practice algorithms and do contests in ACM-ICPC for now. Others tell me to start software development. But As I started digging its really a vast topic and there are many aspects of these, like web design, web-development, iOS-development, android... etc many things. And I am really confused about what should I do just now. Any advice for me to start with?

• DataTables warning (table id = 'example-advanced'): Cannot reinitialise DataTable while using treetable and datatable at the same time

  - by Nyaro

  DataTables warning (table id = 'example-advanced'): Cannot reinitialise DataTable while using treetable and datatable at the same time. Here is my code: <script src="jquery-1.7.2.min.js"></script> <script src='jquery.dataTables.min.js'></script> <script src="jquery.treetable.js"></script> <script> $("#example-advanced").treetable({ expandable: true }); </script> <script> $('#example-advanced').dataTable( { "bSort": false } ); </script> Actually I wanted to get rid of the sorting part of the datatable coz it was giving error in treetable display so i want the sorting part from the datatable out and keep other functions like search and pagination. Please help me out. Thanks in advance.

• When should JavaScript generate HTML?

  - by VirtuosiMedia

  I try to generate as little HTML from JavaScript as possible. Instead, I prefer to manipulate existing markup whenever I can and only generate HTML when I need to dynamically insert an element that isn't a good candidate for using Ajax. This, I believe, makes it far easier to maintain the code and quickly make changes to it because the markup is easier to read and trace. My rule of thumb is: HTML is for document structure, CSS is for presentation, JavaScript is for behavior. However, I've seen a lot of JS code that generates mounds of HTML, including entire forms and content-heavy modal dialogs. In general, which method is considered best practice? In what circumstances should JavaScript be used to generate HTML and when should it not?

• How stressful can a paid side project be?

  - by systempuntoout

  I have developed several side projects for my pleasure at home after my daily job hours and I have never been under pressure with them because you know, if it does not work It can be fixed tomorrow with no rush. I'm tempted to start a paid side project with a contractor and I would like to know, from your experience, if it could be bearable or too stressful. With this paid project I can decide the total amount of hours work in a week upfront and, speaking of my daily job, it has peeks of stressful weeks but also quiet days. How stressful can be a paid side project?

• On mobile is there a reason why processes are often short lived and must persist their state explicitly?

  - by Alexandre Jasmin

  Most mobile platforms (such as Android, iOS, Windows phone 7 and I believe the new WinRT) can kill inactive application processes under memory pressure. To prevent this from affecting the user experience applications are expected to save and restore their state as their process is killed and restarted. Having application processes killed in this way makes the developers job harder. On various occasions I've seen a mobile app that would: Return to the welcome screen each time I switch back to it. Crash when I switch back to it (possibly accessing some state that no longer exists after the process was killed) Misbehave when I switch back to it (sometimes requiring a restart or tasks killer to fix) Otherwise misbehave in some hard to reproduce way (e.g. android service killed and restarted at the wrong time) I don't really understand why these mobile operating systems are designed to kill tasks in this way especially since it makes application development more difficult and error prone. Desktop operating systems don't kill processes like that. They swap out unused pages of memory to mass storage. Is there a reason why the same approach isn't used on mobile? Mobile hardware is only a few years behind PC hardware in term of performance. I'm sure there are very good reasons why mobile operating systems are designed this way. If you can point me to a paper or blog post that explain these reasons or can give me some insight I'd very much appreciate it.

• Programming logic to group a users activities like facebook. E.g. Chris is now friends with A, B and C

  - by Chris Dowdeswell

  So I am trying to develop an activity feed for my site, Basically If I UNION a bunch of activities into a feed I would end up with something like the following. Chris is now friends with Mark Chris is now friends with Dave What I want though is a neater way of grouping these similar posts so the feed doesn't give information overload... E.g. Chris is now friends with Mark, Dave and 4 Others Any ideas on how I can approach this logically? I am using Classic ASP on SQL server. Here is the UNION statement I have so far... SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic,U.Fname + ' ' + U.Sname As FullName, 'said ' + WP.Post AS Activity, WP.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN WallPosts AS WP ON WP.userID = U.userID WHERE WP.Ctime IS NOT NULL UNION SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic,U.Fname + ' ' + U.Sname As FullName, 'commented ' + C.Comment AS Activity, C.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN Comments AS C ON C.UserID = U.userID WHERE C.Ctime IS NOT NULL UNION SELECT U.UserID As UserID, L.UN As UN,Left(U.UID,13) As ProfilePic, U.Fname + ' ' + U.Sname As FullName, 'connected with <a href="/profile.asp?un='+(SELECT Logins.un FROM Logins WHERE Logins.userID = Cn.ToUserID)+'">' + (SELECT Users.Fname + ' ' + Users.Sname FROM Users WHERE userID = Cn.ToUserID) + '</a>' AS Activity, Cn.Ctime FROM Users AS U LEFT JOIN Logins L ON L.userID = U.UserID LEFT OUTER JOIN Connections AS Cn ON Cn.UserID = U.userID WHERE CN.Ctime IS NOT NULL

• Programming languages, positional languages and natural languages

  - by Vitalij Zadneprovskij

  Some programming languages are modeled on machine code, like assembly languages. Other languages are modeled on a natural language, the English language. Others are not modeled on either machine code or natural language. Languages such as PROLOG, for example, don't follow either model. I came across this Perl module Lingua::Romana::Perligata, that allows to write programs using a syntax that is very similar to Latin. Are there programming languages that have less positional syntax? Are there other languages or modules that allow you to write in syntaxes inspired by other natural languages, like French, Hebrew or Farsi? There is a very long list on Wikipedia, but most of those projects are dead. There is a related question on StackOverflow. The answer that was accepted is "Use Google".

• What should JavaScript be renamed to [closed]

  - by Evan Plaice

  Background: I have been watching Douglas Crockford's series of presentation about JavaScript History (which I highly recommend) lately and a one comment of his specifically piqued my attention. The trademark for 'JavaScript' is owned by Oracle History: Due to time constraints at Netscape, the language was literally written in weeks and released in very buggy form. To make it seem more appealing, Netscape picked JavaScript to appeal to the massively growing population of Java developers. Unfortunately, this pissed off Sun and stirred up a lot of controversy between the two organizations. At some point, they came to an agreement whereby Netscape was given permission to use the name as long as Sun owned the trademark. Some people incorrectly refer to JavaScript as ECMAScript because that's where the standard for the language is registered but, aside from it's current marketing-driven label, it doesn't really have a name. Fast Forward Sun goes down only to be swallowed by Oracle, who has no reservations about litigating for profit, now owns the name. So... If Oracle decides and forces JavaScript to take on a new name, what name would best represent the language?

• Can notes/to-dos in code comments sent to code-reviews result in an effective refactoring process?

  - by dukeofgaming

  I want to start/improve a culture of collective code ownership at my company but at a geographically distributed level... I'd say there is some current collective code-ownership mentality, but only at single geographical sites. This is a follow-up to this question: What is the politically correct way of refactoring other's code? I'm just wondering if submitting *just code comments* for code reviews (we have ReviewBoard, possibly upgrading to Crucible) could actually be an effective mechanism to get the conversation started on improving code, without having others feel territorial about their code. For example, if I add: //ToDo: Refactor this code and that code because of reasons X and Y Then, submit it for code review, and it gets accepted... it could be considered as an agreement (which I think is sometimes harder to get with new code up front). At the same time, the author (and others) might have an easier time digesting and accepting the proposal; rejecting a proposal because it might break things will not longer be a valid reason and therefore the fear of making a change is lost... and at the same time, do not invest 10 hours optimizing something that no one thinks it is worth it and opposes to it just out of fear. This is all conjecture, but I'm feeling something like this (submitting refactoring notes in code comments at the code-review process) would work. Has anyone done something like this in practice?, if so, what have been the results?

• How can I move from Java and ColdFusion to Ruby on Rails?

  - by Ciaran Archer

  Currently I work with ColdFusion 9+ and some Java in a Windows environment. Prior to ColdFusion, my background was in Java and JSP. I'm considering a move towards Ruby on Rails, as I think it would be a real challenge, keep things fresh, and provide more job opportunities. In order to get into it, I started to build my personal website in Rails 3.0. But what else can I do to make this transition from what I know now to Ruby and Rails? Are there specific or idiomatic aspects of Ruby or Rails I should keep in mind when switching over from a ColdFusion and Java mindset?

• Review quality of code

  - by magol

  I have been asked to quality review two code bases. I've never done anything like that, and need advice on how to perform it and report it. Background There are two providers of code, one in VB and one in C (ISO 9899:1999 (C99)). These two programs do not work so well together, and of course, the two suppliers blames each other. I will therefore as a independent person review both codes, on a comprehensive level review the quality of the codes to find out where it is most likely that the problem lies. I will not try to find problems, but simply review the quality and how simple it is to manage and understand the code. Edit: I have yet not received much information about what the problem consists of. I've just been told that I will examine the code in terms of quality. Not so much more. I do not know the background to why they took this decision.

• Looking for good Regex book

  - by Cyberherbalist

  I've been trying to get a good grounding with Regular Expressions, and am looking for a single book to do so. I've been going through Amazon.com's listings on this subject, and I've identified a few possibilities, but am unsure which would be best for a C# developer who can write very simple Regexs, but wants to learn more. On a scale of 0-9 where 0 is knowing how to spell "Regex" but nothing else, and 9 where I could write a book on the subject out of my own head, I would place myself at 2. Which of the following would be your choice: Mastering Regular Expressions by Jeffrey E F Friedl Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan Sams Teach Yourself Regular Expressions in 10 Minutes by Ben Forta Beginning Regular Expressions (Programmer to Programmer) by Andrew Watt Regular Expression Recipes for Windows Developers: A Problem-Solution Approach by Nathan A. Good Regular Expression Recipes: A Problem-Solution Approach by Nathan A. Good Now, according to Amazon, "Regular Expressions Cookbook" (REC) above is rated the highest according to user ratings, but only based on 20 reviews. The first one, "Mastering Regular Expressions" (MRE) is rated second based on 140 reviews. This alone suggests that MRE might be by far the best one. But is it best for a relative beginner? Would I perhaps be better getting "Beginning Regular Expressions" (BRE) instead, to start with? Please help me resolve my confusion!

• Software for "High-level" source code (C++) Management

  - by Korchkidu

  after a lot of small-medium projects, I have a lot of libraries and test programs here and there. Also, I must admit that some of the "best practices" I learnt are not that "good" IMHO. In particular, documenting your code and making a "high-level" documentation is not useful in practice: High-level documentation are not maintain up to date = I prefer to read the source code directly; Browsing generated developer documentation is a pain (IMHO) = I prefer to read the source code directly. For that reason, I am looking for a tool who could help me organize all my source code directories in a more "readable manner". What I need is a tool which: Maintains an UML diagram from C++ source code. I don't need source code generation from UML; USE CASE: I am in this super-tool, I notice a design issue, I change the source code, when I get back, the UML diagram is updated; Maintains easily browsable call graphs; Lists references to methods, variables, etc. For example, when I want to see where/when a method is called; Helps writing pseudo-code from C++; Embeds a nice C++ source code browser; Is Open Source would be great; Works at least on Win7. The focus of this tool should be to browse source code to understand what's going on. For example, when you have a newcomer and you need him to go through source code. Do you know any great tool? Thanks in advance. PS: please do not answer doxygen (great tool however).

• using Generics in C# [closed]

  - by Uphaar Goyal

  I have started looking into using generics in C#. As an example what i have done is that I have an abstract class which implements generic methods. these generic methods take a sql query, a connection string and the Type T as parameters and then construct the data set, populate the object and return it back. This way each business object does not need to have a method to populate it with data or construct its data set. All we need to do is pass the type, the sql query and the connection string and these methods do the rest.I am providing the code sample here. I am just looking to discuss with people who might have a better solution to what i have done. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Data.SqlClient; using MWTWorkUnitMgmtLib.Business; using System.Collections.ObjectModel; using System.Reflection; namespace MWTWorkUnitMgmtLib.TableGateway { public abstract class TableGateway { public TableGateway() { } protected abstract string GetConnection(); protected abstract string GetTableName(); public DataSet GetDataSetFromSql(string connectionString, string sql) { DataSet ds = null; using (SqlConnection connection = new SqlConnection(connectionString)) using (SqlCommand command = connection.CreateCommand()) { command.CommandText = sql; connection.Open(); using (ds = new DataSet()) using (SqlDataAdapter adapter = new SqlDataAdapter(command)) { adapter.Fill(ds); } } return ds; } public static bool ContainsColumnName(DataRow dr, string columnName) { return dr.Table.Columns.Contains(columnName); } public DataTable GetDataTable(string connString, string sql) { DataSet ds = GetDataSetFromSql(connString, sql); DataTable dt = null; if (ds != null) { if (ds.Tables.Count 0) { dt = ds.Tables[0]; } } return dt; } public T Construct(DataRow dr, T t) where T : class, new() { Type t1 = t.GetType(); PropertyInfo[] properties = t1.GetProperties(); foreach (PropertyInfo property in properties) { if (ContainsColumnName(dr, property.Name) && (dr[property.Name] != null)) property.SetValue(t, dr[property.Name], null); } return t; } public T GetByID(string connString, string sql, T t) where T : class, new() { DataTable dt = GetDataTable(connString, sql); DataRow dr = dt.Rows[0]; return Construct(dr, t); } public List GetAll(string connString, string sql, T t) where T : class, new() { List collection = new List(); DataTable dt = GetDataTable(connString, sql); foreach (DataRow dr in dt.Rows) collection.Add(Construct(dr, t)); return collection; } } }

• How to test a localized WPF application in visual studio 2012

  - by Michel Keijzers

  I am trying to create a localized application in C# / WPF in Visual Studio 2012. For that I created two resource files and changed one string in a (XAML) window to use the resource files (instead of a hardcoded string). I see the English text from the resource file, which is correct. However, I want to check if the other resource file (fr-FR) also works but I cannot find a setting or procedure how to change my 'project' to run in French. Thanks in advance.

• Advise on career development [closed]

  - by Mike Young

  I am an amateur programmer working at a start-up. I didn't try coding at college. I've been working for 2 months now on web development. I'm satisfied with my progress. My project will go live soon. I work on front-end and my colleague integrates my work in his. So I decided to learn back-end technologies so that I would be able to work on a project from scratch, help my company build up. I recently got to know about the technologies used by fb and was fascinated to learn ,work on them,keep motivating myself. Now I want to work on building a product from scratch, be good at database concepts, a language like ruby or python, and get to know load balancing, dynamic requests from servers, hosting a website, real time communication, secured login, implementing sophisticated search feature for the app, using git by the end of the project.I would like to be a full stack developer in due course of time and learn everything in detail. I decide to keep myself out of time frame, learn every concept in detail.I would like to use both rdbms and non relational dbm for the project. I have no experience except some beginner knowledge in html5,css and JavaScript. I would like to get some advice on how to proceed forward step by step,flow what technologies to pick up and project idea which includes all the above.

• book about psychology of decision and psychology of human

  - by boos

  I'm a unix developer and i want to make career in project/people management as first step. I think sometimes is better to have good communication skill and in general more human skill to make career more fast. Almost in Italy, a lot of people made career development more fast for his human skill and not for his technical skill. Anyone have read some book about psychology to better manage how people and personality work and to exploit decision making situation in the right way? I have found some interesting book about people personality and psychology of decision, but i am in doubt about the usefulness about reading such book. anyone have some experience in this path ? Anyone have found useful to read similar book about how people work, to manage career development in a more fast way and handle people and decision in a more useful way? i have already read peopleware. The table of content of one of this book have: 1 - Judicment and decision 2 - Euristics and sistematics error 3 - Estimating probability and frequency prediction 4 - Risk and decision 5 - rappresentation and decision 6 - Memory, attention and decision. Etc. what do you think about ?
