• How do you balance between "do it right" and "do it ASAP" in your daily work?

  - by Flot2011

  I find myself pondering this question times and times again. I want to do things the right way, to write a clean, understandable, correct code that is easy to maintain, but what I really do pretty often is writing a patch upon patch just because there is no time, clients are waiting, a bug should be fixed overnight, the company is losing money on this problem, a manager is pressing hard etc. etc. I know perfectly well that in a long shot I am wasting much more time on these patches, but as this time is spread over months of work, nobody cares. Also, as one of my managers used to say, we don't know if there will be this long shot if we will not fix it now. I am sure I am not the only one entrapped in this endless real/ideal choices. So how you, fellow programmers, are coping with this?

• Does having a higher paid technical job mean you do not get to code any more?

  - by c_maker

  I work at a large company where technical people fall roughly in one of these categories: A developer on a scrum team who develops for a single product and maybe works with other teams that are closely related to the product. An architect who is more of a consultant on multiple teams (5-6) and tries to recognize commonalities between team efforts that could be abstracted into libraries (architects do not write the library code, however). This architect also attends many meetings with management and attempts to set technical direction. In my company the architect role is where most technical people move into as the next step in their career. My questions are: Do most companies work such a way that their highest paid technical people are far removed from writing code? Is this a natural tendency for a developer's career? Can a developer have it all (code AND set direction?)

• Role of MBR in the booting process

  - by pg4421

  I am new to stack overflow. So please correct me if my question seems irrelevant or stupid. I read here in Booting Process : The job of the primary boot loader is to find and load the secondary boot loader (stage 2). It does this by looking through the partition table for an active partition. When it finds an active partition, it scans the remaining partitions in the table to ensure that they're all inactive. When this is verified, the active partition's boot record is read from the device into RAM and executed. The question is that I am having a Hard disk which has two Operating System images windows and ubuntu and hence both partitions in which they reside are active. Then why do we have only one active partition always? (I know that active partition is one of the primary partition but then why we are giving special reference to one primary partition? ) I am confused a bit. Please solve my query. Thank you so much.

• Dump an arbitrary object To Html String

  For debugging purposes me and my collegue wanted to dump details of the arbitrary object, and created function that uses LINQPad Dump functionality (thanks to http://stackoverflow.com/a/6035014/52277 and original http://linqpad.uservoice.com/forums/18302-linqpad-feature-suggestions/suggestions/447166-make-dump-extension-method-available-in-visual-s discussion)    public static string DumpToHtmlString<T>(this T objectToSerialize)        {            string strHTML = "";            try            {                var writer = LINQPad.Util.CreateXhtmlWriter(true);                writer.Write(objectToSerialize);                strHTML = writer.ToString();            }            catch (Exception exc)            {                Debug.Assert(false, "Investigate why ?" + exc);            }            return strHTML;        }You will need to add the linqpad executable as a reference in your project.TO DO similar in plain text ,look at https://github.com/ServiceStack/ServiceStack.Text StringExtensions , e.g. JsonSerializer/CsvSerializer or http://objectdumper.codeplex.com/

• Writing a basic C Shell - understanding argv[] [on hold]

  - by Flame

  I have an assignment for my class to write a basic C Shell. I have found many pages that explain parts of it and some fully implemented code. I'm not going to copy, i'm just using it right now as a way to get started. So I'm at the beginning of this project obviously. One example I am looking at parses the user's input and stores a pointer to the beginning of the argument in char *argv[3]; Am I just misunderstanding this or would this technically break if there are more than 3 arguments? (say /a.out arg1 arg2 arg3 etc). Would I wanna malloc this somehow? I know a.out is considered argv[0], and the arguments argv1 - however many there are. It's probably bad practice to have too many arguments for a program, but I still would at least want to address it as I don't know what my TA's are going to use to test my shell.

• Mouse on screen lags

  - by Jeggy

  I just made a fresh install of Ubuntu 13.10 64bit on my Dell XPS 15 laptop. My mouse lags/glitches/blinks each time something is loading in Ubuntu. when a youtube video is playing in the background it blinks all the time, and it also blinks for each character that I write, it's very annoying. It also blinks for each time the Blinking Cursor in a text field blinks. When I have just booted up my laptop it can be away for a second or more (than after it comes back it goes away for a second or more and this happends for awhile), so I have no chance of seeing the mouse on my screen.

• Help with cron syntax

  - by Randy

  I need to setup a cronjob on my webhost. The documentation for my webapp reads as follows: you will need to create following cronjob: /public_html/cake/console/cake -app /public_html/app master Also, I want any output written to a log file. My hosts documentation says this: You can have cron send an email everytime it runs a command. If you do not want an email to be sent for an individual cron job you can redirect the command's output to /dev/null like this: mycommand /dev/null 2&1 Can someone help me write the cron job? I dont know the syntax at all. Thanks for the help!

• Best container to store this information

  - by user2368481

  I'm trying to write a smallish system as a homework excercise, I don't have much experience with containers and I'm not sure the best way of storing this data would be: Incident Records object holds instants of Incident Report. Report is a superclass which has 3 subclasses, Police, Fire or Medical. Record must must record which of these types apply, and which response teams are to be involved. So Record has to keep track of the Report objects, the type of the report (Police, Fire or Medical) and the teams involved in the reports. I was initially thinking of an array but that wouldn't be sufficient to hold all the info. Record<>---------Report<|----------Police, Fire or Medical

• Programming Windows Identity Foundation - ISBN 978-0-7356-2718-5

  - by TATWORTH

  This book introduces a new technology that promises a considerable improvement on the ASP.NET membership system. If you ever had to write an extranet, system you should be aware of the problems in setting up membership for your site. The Windows Identity Foundation promises to be an excellent replacement. Therefore the book Programming Windows Identity Foundation - ISBN 978-0-7356-2718-5 at  http://oreilly.com/catalog/9780735627185, is breaking new ground. I recommend this book to all ASP.NET development teams. You should reckon on 3 to 5 man-days to study it and try out the sample programs and see if it can replace your bespoke solution. Rember this is version 1 of WIF and give yourself adequete time to read this book and familiarise yourself with the new software. Some URLs for more information: WIF home page at http://msdn.microsoft.com/en-us/security/aa570351.aspx The Identity Training Kit at http://www.microsoft.com/downloads/en/details.aspx?displaylang=en&FamilyID=c3e315fa-94e2-4028-99cb-904369f177c0 The author's blog at http://www.cloudidentity.net/

• Looking for parallel programming problem

  - by Chris Lieb

  I am trying to come up with a problem that is easily solvable in a parallel manner and that requires communication between threads for a test. I also am trying to avoid problems that require require random waits, which rules out dining philosophers and producer-consumer (bounded buffer), two of the classics. My goal is for the student to be able to write the program in less than 20-30 minutes in front of a computer not knowing of the problem beforehand. (This is to prevent preparation more than to come up with something novel.) I am trying to stress the communication aspect of the program, though the multi-threaded nature is also important. Does anyone have some ideas? Edit: I'm using Google Go for the language and testing comprehension of the goroutines/channels combo vs an actors library that I authored.

• How to run/test JavaScript? [closed]

  - by user702

  I'm reading David Flanagan's "JavaScript: The Definitive Guide, 6th ed". It only actually tells users how to run JS code on page 311, where users are told of the following solutions: "Client-side JavaScript code is embedded within HTML documents in four ways: Inline, between a pair of <script> and </script> tags From an external file specified by the src attribute in a <script> tag In an HTML event handler attribute, such as onclick or onmouseover In a URL that uses the special javascript: protocol." I was wondering what professional JS developers use to write and test their code: Do they use a good text editor with syntax high-lighting + autocompletion, hit F5 in the browser to reload the page every time they make a change, and use some add-on in the browser to investigate errors? Or are there full-fledged IDE's similar to MS VisualStudio for non-web languages?

• How can I improve these online java programming puzzles I wrote for my (middle/high school) students?

  - by Arcymag

  I'm teaching some middle and high school students programming right now, and I found that some of them really liked online programming puzzles. So I created http://www.kapparate.com/coder/ , and right now there's 4 categories of puzzles. All the puzzles are set up right now so that variables are pre-initialized, and the user plugs in some code in the middle. For example, the problem might say these are pre-initialized: int x = ????; int y = ????; int z; and then the program might ask the student to write the final line of code: z = x + y;. Now I know I could go a long way in improving the usability of this site (like having an area that lists the pre-defined variables), but I was wondering if this concept seems sound. I know some sites have kids fill in functions, but not all of my students know what functions are yet, and I'm trying to introduce online programming puzzles before that.

• possible to use an IP derived from Dynamic DNS in htaccess IP allow/deny commands?

  - by user115745

  On a website I manage, I want to use an .htaccess file to allow access to a certain administrative directory only from my home IP address, which is dynamically assigned by my ISP and therefore changes -- not regularly, but it does happen. I also have an account from DynDNS and have one of the auto-update clients making sure it always points to my actual home IP address. I don't actually host anything at home; I just have set up the Dynamic DNS account. Is there any way to combine these features: that is, is it possible write the .htaccess allow/deny commands at my outside webhost in a way that my home IP address is not hard coded into the command, but instead is somehow derived from the Domain Name that the DynDNS has assigned me, by doing a real-time lookup every time the directory's .htaccess file is hit? Thank you.

• What is ethical/unethical while seeking help on the web with programming assignments?

  - by HelpNeeder

  I have used the web and Stack Overflow extensively during the past month or so in creating my final project for my C# class. I have used so much code that I didn't write myself that I feel I am being unethical by not giving proper credit to the people who helped me; or the websites that have provided excellent examples. Is it unethical to publish work which was created by me, even though its hardest problems were solved by other people? Should I credit these people for helping me with my assignment? Or the web sites which provided examples?

• Do you use i-->0 for backward loops?

  - by maaartinus

  Some people write for (int i=N; i-->0; ) doSomething(i); instead of for (int i=N-1; i>=0; --i) doSomething(i); for backward loops. The --> "operator"1 looks very confusing at the first glance, but it's trivial: i-->0 simply parses as (i--)>0, and once you get it, you see it immediately. The main disadvantage is the strange look. The advantage is that you'll get it always right (unlike the more verbose version offering the possibility to forget something, which really happened to me a couple of times). What do you think about using the --> "operator"? 1First time I saw the funny term in a comment to this question today.

• Learning the nuances of a language (C++)

  - by prelic

  So I'm a recent college graduate, and I really enjoy working in C++; I worked with it a lot in school, and would like to pursue a career writing in C or C++. The problem I'm having is that I'm trying to learn the nuances of C++. I'm not talking about the basics, or even advanced concepts like templates, namespaces, etc...I'm talking about the real nitty-gritty stuff like undefined behavior and stuff like that. When I'm interviewing, and they put a bizarre piece of C++ code in front of me, and ask me what the output will be, I want to be able to nail those questions. Obviously experience is a great way to learn, but when I write code for practice, I [obviously] know what it does. Reading open-source projects have been good practice, but I find that there tends to be an enormous learning curve just understanding the organization of the code (because the projects tend to be large). So basically what I'm asking is, what should I do now? Any tips are greatly appreciated!

• Process monitoring in Linux environment?

  - by poly

  I'm trying to write a multi threaded/processes application and it need to know how to monitor a process from another process all the time. So here is what I have, I have a 2 processes, each with multiple threads that handle the network part, then another 2 process also with multiple threads that interact with DB and with the network processes, what I need to do is that if for example one of the network processes goes down the DB process start sending to the live network process until the second one is up again. I'm using fifo between the DB and the network process. I was thinking of sending messages with message passing all the time but not sure whether this is a good idea or I need to use some other IPC for this issue, or probably neither is good and I need to use entirely something else?

• Writing a Data Access Layer (DAL) for SQL Server

  In this tip, I am going to show you how you can create a Data Access Layer (to store, retrieve and manage data in relational database) in ADO .NET. I will show how you can make it data provider independent, so that you don't have to re-write your data access layer if the data storage source changes and also you can reuse it in other applications that you develop.

• Rewriting software using Agile methodologies

  - by Asier

  Suppose you have to rewrite an entire application using Agile methodologies, how would you do it? I guess you could write a big bunch of user stories based in the behavior of your current system. And then implement them in small iterations. But this wouldn't mean that we have the requirements UP FRONT?? Also, when would you start releasing? Agile says we should release early and often, but it doesn't make much sense to release before the complete rewrite has been completed. Anybody has used Agile before to rewrite software? How did you do it?

• Program/Wrapper (how do you call it) to automate a certain script

  - by user10324

  In this question a script is provided, that minimizes all the other windows except the active one. But the thing is, to trigger this script a (shortcut) key-combination has to be pressed. I would love it, if it would be possible to automate this behavior, i.e. no matter what I do, only the active window is not minimized. This way I cannot view more then one open window at the same tine, which is what I'm after. Is it possible to write a script, that does this ? I a question I asked a while ago (where I learned about the above script), someone said, the proper way to do this, would be through a wrapper through which every program starts. I would also be very happy with a more sloppy solution, like activating this script 100 times per second (simulating pressing the shortcut combination a 100 times per second), if it is feasible - although I was warned, that that may not be a very good idea.

• What framework for text rating site?

  - by problemofficer

  I want to start a "rate my"-style site. The rated objects are mostly texts. I want it to be rather simple. Features I need: object rating (thumb up, thumb down) object comments object tags related object presentation based on tags user authentication and management private message system sanity checks for text inputs (i.e. prevention of code injections) cache open source runs on GNU/Linux I would gladly take something that is tailored for my scenario but a generic framework would be fine too. I simply don't want to write stuff like user authentication that is been written a million times and risking security flaws. Programming language is irrelevant but python/php preferred.
