• Is listing developer's full names in splash screen or about box still a widely spread and desirable practice?

  - by Pierre 303

  Just like in the closing credits of movies, some software vendors list the full names of the team that worked on the piece of software you are using. They are usually displayed in the splash screen (Photoshop) ... or in the about box (Traktor). In the demoscene, it is a mandatory practice, like in the movie industry. How do you see that in your own software? Is there any reason why not doing it? Is there any reason encouraging companies to do it?

• Software solution from the 2000's, should I attempt to patch or remake the whole thing?

  - by ShadowScripter

  I was sent out to discuss a system that a certain company is currently using and what should be done with it. The company manufactures various carton displays. This system was developed to keep track of clients, orders and prices. Lots have happened since the system was created and the system is now, as the manager described it, "locked up" and "problematic", which I translate as "not dynamic" and "unstable". Some info about the system It was developed around the year 2000 Fairly small system, 2-5 users, 6 forms, ~8 tables with average quantities of data Built on early Visual Basic, forms created with the drag and drop design. Interface is basically just a window with a menu and some forms Uses MSSQL database (SQL2005 server) to store data and ODBC driver to query, data was migrated from excel before this system, and before excel it was handled, calculated and written by hand and paper Users work in Microsoft XP environment (and up) Their main problem is that they can't adjust and calculate prices, can't add new carton types etc, correctly anymore because they can't (or rather, they don't know how to) touch the data on the server. I suggested 3 possible solutions Attempt to patch the current system Create a fresh new interface (preferably similar environment, VB.net or VB based) Bring it back to an Excel solution, considering it is such a small system There might be more options, but these are the ones I could think of. My questions are What should I recommend and why? What is or could be the pros and cons of these alternatives? Are there other (possibly better) alternatives?

• svn-based versioning tool, problem with network timeout

  - by Scarlet

  My dev team was committed a versioning tool based on Subversion to run on Windows (our svn client is sliksvn). We're developing with Delphi XE2, should that matter. We're asked to implement a "check for updates availability" feature, which has to work as follows: Connect to the SVN repo via svn+ssh protocol; See if there are changes to receive and list them; Let the user decide if he wants to receive changes or not. We don't have a great knowledge on svn, so we thought to implement that thing client side by a certain number of CreateProcess calls that wrap directly proper svn commands. Anyways what we perceived is that if network problems should arise, such like a connection drop, svn client hangs forever waiting for the operation to close instead of failing for timeout. We know that CreateProcess can be given a timeout argument, but it wouldn't be correct to use it, as we can't know from outside how long will be the svn operation taking to complete. Is there any way to avoid that deadlock?

• getting Jomsocial profile fields [closed]

  - by niravshah_php

  I am developing a custom module in Joomla for searching user profile in many ways. I want country, state and some other custom profile fields to be searched. I have tried importing jomsocial library class of profile fields, but I have one issue. I have no object to pass into that function as a parameter. I have tried to fetch field values from database, but I got them in as a single string which is not filtered. Can anyone help me to use jomsocial library in custom module Joomla?

• Are SMART goals useful for programmers?

  - by Craig Schwarze

  Several organisations I know use SMART goals for their programmers. SMART is an acronym for Specific, Measurable, Achievable, Relevant and Time-Bound. They are fairly common in large corporations. My own prior experience with SMART goals has not been all that positive. Have other programmers found them an effective way to measure performance? What are some examples of good SMART goals for programmers (if they exist).

• Visual Studio 2010 editor painfully slow [closed]

  - by Daniel Gehriger

  I'm running out of patience with MS VisualStudio 2010: I'm working on a solution containing ~50 C++ projects. When using the editor, I experience a lag of 1 - 2 seconds whenever I move the cursor to a different line, or when I move to a different window, or generally when the editor losses and gains focus. I went through a whole series of optimizations, to no avail: installed all hotfixes for VS2010 disabled all add-ins and extensions disabled Intellisense deleted all temporary files created by VS2010 disabled hardware acceleration unloaded all but 15 projects disabled tracking changes closed all but one window and so on. This is on a Dual Core machine with SSD harddrive (verified throughput 100MB/s), enough free space on HD, Windows 7 Pro 32-bit with 3GB of RAM and most of it still free. Whenever I type a letter, CPU usage of devenv.exe goes to 50 - 90% in process monitor for 1 - 2 seconds before returning to 5%. I used Process Explorer to analyze registry and file system access, and I only notice frequent accesses to the .sln file (which is quiet small), and a few registry reads, but nothing that would raise a red flag. I don't have this problem with solutions containing less projects, so I'm inclined to think that it's related to the number of projects. For your information, the entire solution has been migrated over the years from VS2005 to VS2008 to now VS2010. Does anyone have any ideas what else I could do to resume work on this project, other than returning to VS2008?

• what is message passing in OO?

  - by Tom

  I've been studying OO programming, primarily in C++, C# and Java. I thought I had a good grasp on it with my understanding of encapsulation, inheritance and polymorphism (as well as reading a lot of questions on this site). One thing that seems to popup up here and there is the concept of "message passing". Apparently, this is something that is not used whilst OO programming in today's mainstream languages, but is supported by Smalltalk. My questions are: What is message passing? (Can someone give a practical example?) Is there any support for this "message passing" in C++, C# or Java?

• Good resources for language design

  - by Aaron Digulla

  There are lots of books about good web design, UI design, etc. With the advent of Xtext, it's very simple to write your own language. What are good books and resources about language design? I'm not looking for a book about compiler building (like the dragon book) but something that answers: How to create a grammar that is forgiving (like adding optional trailing commas)? Which grammar patterns cause problems for users of a language? How create a compact grammar without introducing ambiguities

• I have a stacktrace and limit of 250 characters for a bug report

  - by George Duckett

  I'm developing an xbox indie game and as a last-resort I have a try...catch encompassing everything. At this point if an exception is raised I can get the user to send me a message through the xbox however the limit is 250 characters. How can I get the most value out of my 250 characters? I don't want to do any encoding / compressing at least initially. Any solution to this problem could be compressed if needed as a second step anyway. I'm thinking of doing things like turning this: at EasyStorage.SaveDevice.VerifyIsReady() at EasyStorage.SaveDevice.Save(String containerName, String fileName) into this (drop the repeated namespace/class and method parameter names): at EasyStorage.SaveDevice.VerifyIsReady() at ..Save(String, String) Or maybe even just including the inner-most method, then only line numbers up the stack etc. TL;DR: Given an exception with a stacktrace how would you get the most useful debugging infromation out of 250 characters? (It will be a .net exception/stacktrace)

• DDD and validation of aggregate root

  - by Mik378

  Suppose an aggregate root : MailConfiguration (wrapping an AddressPart object). The AddressPart object is a simple immutable value object with some fields like senderAdress, recipentAddress (to make example simple). As being an invariant object, AddressPart should logically wrap its own Validator (by the way of external a kind of AddressValidator for respecting Single Responsibility Principle) I read some articles that claimed an aggregateRoot must validate its 'children'. However, if we follow this principle, one could create an AddressPart with an uncohesive/invalid state. What are your opinion? Should I move the collaborator AddressValidator(used in constructor so in order to validate immediately the cohesion of an AddressPart) from AddressPart and assign it to aggregateRoot (MailConfiguration) ?

• New Job Over Budget

  - by moneylotion

  I recently started a new job as a contract developer, and my non-developer boss of about two weeks ago gave me the task to re-create an app from another language and developer that he will reuse with multiple clients (replacing the front-end), that I estimated would take longer than his estimate of 12 hours. Two weeks later, I'm 230% over-budget. I admit this was my 2nd web app, I had been a wordpress developer in the past, so I am somewhat new to code igniter, but not shabby php by any means. My boss hired me knowing this and I was clear that it would take longer than his 12 hours. He's seen me in the office on task for 2 weeks, he should be somewhat prepared for this bill. Do I expect the full amount of hours, or do I filter against how much of learned? Can I bill for research as a developer?

• Organizing single page code well with Notepad++

  - by Hudson

  I've a c# file that will contain, most likely 10,000+ lines of code. I'd like to break this file into tabbed segments, so I can organize each method into a certain tab and label the tab something like : initial setup, helper functions,execution logic,list structures,global variables, etc. If I were using PHP I would have separate files and use include(); to include the separate files. What can be done, following the same style, with c#?

• How do I get "ruby" to do what "ruby1.9.1" does?

  - by Daniel

  I want to start off by saying... I really don't need to be using 1.9.2. I understand that you don't ever, ever use Python 3.2, so if the common advice is that I should use 1.8, I'll do that. But don't tell me to do that because it's easier. Whatever version I should be using, though, the question is still relevant: What's a good way to make one command do another command? (I suppose I could write a c program to launch ruby1.9.1, call the executable ruby, and put it in my bin, but this seems like less than a good idea)

• How can I show Thunderbird Lightning tasks and events in the Gnome Clock applet?

  - by Niriel

  We used to have this functionality with Evolution: clicking on the date-time in the gnome panel would show a list of events/tasks/appointments from the Evolution Calendar. As an interesting side effect, one would receive alarm notifications even when Evolution wasn't running. Now that Thunderbird is the default email client, I'd imagine that there is a similar functionality for Lightning (Thunberbird's calendar). I just can't find it. Maybe it's not ready ?

• Temporary R+W CIFS share for non-root accounts?

  - by Coder

  I want to set up a cross platform mail client (Thunderbird), and so far I want to use NAS as a profile store. The NAS is CIFS based, and can be mounted on both Windows and Ubuntu. Also the locking works fine for mutex, and setup seems to work as a proof of concept. The problem is the Linux mount. Since I'm using a laptop, I'm not always connected to network, hence, I can't use the /etc/fstab to set up CIFS share with a modified group id. And the share has to be mounted using mount -t cifs ..., which causes it to be owned by root, and owned so badly, that it can't be chowned to the regular user account. This causes read only issues for Thunderbird, which seem to be solved if Thunderbird is launched via sudo. But I would like to avoid that and use a script to mount the share on-demand to a profile location, with profile based privileges and access rights. Is there a way to achieve that?

• Cloned partition not seen correctly by disk utility & gparted

  - by enrico

  Some days ago I cloned my /dev/sda1 partition with clonezilla in partition-to-partition mode to /dev/sda3. It worked, but now that I've finished the setup of system in /dev/sda3, I wanna reinstall /dev/sda1 for other stuffs. This partition is NOT mounted, but ubuntu's DISK UTILITY thinks it is, while it doesn't see as mounted the currently active / partition /dev/sda3. This is the df- TH output : Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 ext4 32G 6.2G 24G 21% / udev devtmpfs 2.2G 13k 2.2G 1% /dev tmpfs tmpfs 845M 906k 844M 1% /run none tmpfs 5.3M 0 5.3M 0% /run/lock none tmpfs 2.2G 115k 2.2G 1% /run/shm /dev/sdb1 fuseblk 321G 147G 174G 46% /Dati Gparted instead, sees /dev/sda1 as NOT mounted (checked with Information option), but it display the BOOT flag on this partition, while the real booted partition /dev/sda3, hasn't it.

• How do I install a DVD decryption library?

  - by rocket101

  I recently built a computer running Ubuntu 11.10. It works great, except for one thing. With some video DVDs, when I insert them into my drive, the movie player just says "An error occurred. Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed." My mac plays the DVD just fine. What is a DVD decryption library, and how can I install it? Thanks! EDIT: I need LEGAL way to do this. All I want is to be able to use this computer as a HTPC!

• Why does Ubuntu only detect one USB LAN adapters at a time?

  - by EGO

  I try to connect real switch with my computer for an exam preparation, for this purpose I need more than one LAN cards, and there is only one built in LAN card in my computer. So, to get more LAN cards, I bought 4 USB Ethernet adapters (as I have 4 usb ports in may laptop 2 usb 2.0 ports, 2 usb 3.0 ports). When I plug these adapters in my computer Ubuntu only detects one LAN card from 2.0 usb ports, and one LAN card from 3.0 ports. And sometimes detects only one USB LAN from all the usb ports. Actually the real problem is Ubuntu shows these USB LAN adapters in the "lsusb", but does not list them in "ifconfig". Kontron (Industrial Computer Source / ICS Advent) is my LAN USB ethernet. abc@ubuntu:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.

• How to get faster graphics in KVM? VNC is painfully slow with Haiku OS guest, Spice won't install and SDL doesn't work

  - by Don Quixote

  I've been coming up to speed on the Haiku operating system, an Open Source clone of BeOS 5 Pro. I'm using an Apple MacBook Pro as my development machine. Apple's BootCamp BIOS does not support more than four partitions on the internal hard drive. While I can set up extended and logical partitions, doing so will prevent any of the installed operating systems from booting. To run Haiku directly on the iron, I boot it off a USB stick. Using external storage is also helpful because I am perpetually out of filesystem space. While VirtualBox is documented to allow access to physical drives, I could not actually get it to work. Also VirtualBox can only use one of the host CPU's cores. While VB guests can be configured for more than one CPU, they are only emulated. A full build of the Haiku OS takes 4.5 under VB. I had the hope of reducing build times by using KVM instead, but it's not working nearly as well as VirtualBox did. The Linux Kernel Virtual Machine is broken in all manner of fundamental ways as seen from Haiku. But I'm a coder; maybe I could contribute to fixing some of those problems. The first problem I've got is that Haiku's video in virt-manager is quite painfully slow. When I drag Haiku windows around the desktop, they lag quite far behind where my mouse is. It's quite difficult to move a window to a precise position on the screen. Just imagine that the mouse was connected to the window title bar with a really stretchy spring. Also Haiku's mouse lags quite far behind where I have moved it. I found lots of Personal Package Archives that enable Spice from QEMU / KVM at the Ubuntu Personal Package Arhives. I tried a few of the PPAs but none of them worked; with one of them, the command "add-apt-repository" crashed with a traceback. There is a Wiki page about Spice, but it says that it only works on 64-bit. My Early 2006 MacBook Pro is 32-bit. Its Apple Model Identifier is MacBookPro1,1; these use Core Duos NOT Core 2 Duos. I don't mind building a source deb for 32-bit if I can expect it to work. Is there some reason that Spice should be 64-bit only? Does it need features of the x86_64 Instruction Set Architecture that x86 does not have? When I try using SDL from virt-manager, the configuration for Local SDL Window says "Xauth: /home/mike/.Xauthority". When I try to start my guest, virt-manager emits an error. When I Googled the error message, the usual solution was to make ~/.Xauthority readible. However, .Xauthorty does not exist in my home directory. Instead I have a $XAUTHORITY environment variable. There is no way to configure SDL in virt-manager to use $XAUTHORITY instead of ~/.Xauthority. Neither does it work to copy the value of $XAUTHORITY into the file. I am ready to scream, because I've been five fscking days trying to make KVM work for Haiku development. There is a whole lot more that is broken than the slow video. All I really want to do for now is speed up my full builds of Haiku by using "jam -j2" to use both cores in my CPU. I may try Xen next, but the last time I monkeyed with Xen it was far, far more broken than I am finding KVM to be. Just for now, I would be satisfied if there were some way to use my USB stick as a drive in VirtualBox. VB does allow me to configure /dev/sdb as a drive, but it always causes a fatal error when I try to launch the guest. Thank You For Any Advice You Can Give Me. -

• Unable to login following permission changes in device manager (11.10 + Gnome)

  - by Symanuk

  (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers
