• dpkg reports error on package icaclient

  - by Photonics1

  I installed the icaclient (it's a client for Citrix) a while back. I don't exactly remember what I did to get it working but it was enervating. I had to install some old packages not even avaiable for ubuntu (12.04) and in the end I used some stuff from old rpms. Anyway the client is more or less working now but I always get a dpkg error when installing or updating something. The (translated) error message is something like: dpkg: Error while processing icaclient:i386 (--configure): subprocess installed post-installation-script return errorcode 2 I just want to tell dpkg to ignore this or remove this post-install-script but I don't know how. Thanks!

• Audio libraries for PC indie games [closed]

  - by bluescrn

  Possible Duplicate: Cross-Platform Audio API Suggestions What options are out there these days for audio playback/mixing in C++? Primarily for Windows, but portability (particularly to Mac and iOS) would be desirable. For a small indie game, potentially commercial, though - so I'm looking for something free/low-cost. My requirements are fairly basic - I don't need 3D sound, or many-channels - simple stereo is fine. Just need to be able to mix sound effects and a music stream, maybe decoding one or more compressed audio formats (.ogg/.mp3 etc), with all the basic controls over looping, pitch, volume, etc. Is OpenAL more-or-less the standard choice, or are there other good options out there?

• Not assigning Bugs to a specific user

  - by user2977817

  My question: Is there a benefit to NOT assigning a Bug to a particular developer? Leaving it to the team as-a-whole? Our department has decided to be more Agile by not assigning Bugs/Defects to individuals. Using Team Foundation Server 2012, we'll place all Bugs in a development team's "Area" but leave the "Assigned To" field blank. The idea is that the team will create a Task work item which will be assigned to an individual and the Task will link to the Bug. The Team as a whole will therefore take responsibility for the Bug, not an individual, aligning to Scrum - apparently. I see the down side. The reporting tools built into TFS become less useful when you cannot sort by assigned vs unassigned, let alone sorting by which user Bugs are assigned. Is there a benefit I'm not seeing? Besides encouraging teamwork by putting the responsibility on the team-as-a-whole instead of an individual?

• Moving dozens of existing standalone retail sites to one central inventory database: what should I know going in?

  - by palintropos

  This will be the first project of this scale that I have attempted, and the first time I have run a website at all (much less dozens) using an off-site database. In particular, I'd like to know: what sort of optimizations I should read up on to make this run as smoothly as possible? any pitfalls/gotchas wiser, more experienced folk are aware of I should be on the lookout for, and what damage-control and preventative measures I should take against the nightmare scenario of the main server (hosting the database) having an outage, grinding over 100 websites to a halt (because they have no access to the product data).

• Can't get whole picture on the screen of a new monitor

  - by Gillian

  I have a 24inch, VM2453mh-LED, Viewsonic monitor using a Radeon 6570HD video card. Both are new. Viewsonic says the optimum size is 1920x1080. At this size the picture is beautiful, but it overlaps the screen vertically and horizontally. I am using Ubuntu 11.10, the Gnome 3 version, not Unity. On the Overview screen, the vertical icons are nearly off screen. Only the right edge shows. I opened the monitor's control menus to see if I could adjust it, but both the H/V Position and Horizontal Size are grayed out. I tried a 1600x1200 setting, and the picture was in bounds, but the quality was less, and it was stretched horizontally. The two monitor menu options were grayed out just like with the 1920x1080 setting. Can someone tell me how to resolve this problem?

• Receive anonymous users' input by web upload form or email. Any online service for that?

  - by sja

  Are you aware of any online service or online "platform" allowing users, not previously registered, to upload pairs of picture+comment to a database? It would be a collaborative database of picture+comment pairs. I'm not going wiki or googlegroup, picasa or such because I'd like the user to have the least to do to participate, that is e.g.: take a picture with his phone and email it to an email to an email address. Or go to a web page with an upload form, type in a description, hit OK and that's it. And the goal is also that it be as hassle-less to put up as possible. Yeah I know, it can't programme itself to my requirements :) by I'm suspecting there's a tool or tool combination going a decent way through my needs. Thanks for any info/advice! SJA (NB the final goal is a kind of crowd-sourced census of specific urban items. If you have comment about the potential for spam-overload of my idea, other than "you're doomed", you're welcome!)

• What is important when starting GUI programming, and pick from widget libraries [closed]

  - by jokester

  I have been a CLI programmer, and recently I found it will be a plus to learn GUI programming. In past, my experience and knowlegde was a bit messy. So you may imagine many detour were there in my way, that is true. And I want to avoid getting lost again if possible. When googling about existing GUI framework, I found it is hard to choose my start point from GTK, QT, and lot of less famous peers. What are important factors when you guys are facing that problem? Will it be a good idea to pick a small enough library and feel its fundamental ideas?

• Render 2D textures on a 3D object's face

  - by www.Sillitoy.com

  I am not familiar with 3D graphics, and I'd like to know the right way to render some 2D figures on different points of a wider face of a 3D object. My 3D object is just a cube representing a poker table. I have a 2D png for players' placeholders, and I'd like to render these figures on the 3D object where needed. An alternative solution would be to render the whole face with a big picture containing all the placeholders figures. However, it would be a waste of memory and thus less efficient. What do you suggest?

• How do I tell my boss he made the wrong choice? [migrated]

  - by SomeKittens

  Recently, our biggest product failed majorly because we'd only used outsourced labor to do it, and they never tested anything, etc. Finally, our CEO decided that the US team should learn the code and fix it up. (Not a total rewrite, but lots of formatting/style changes, refactoring, etc). However, he knows next to nothing about programming (thankfully, he admits it). He had been grooming me to take on the project manager position, but I had to go back to college. Now he gave it to another programmer who is naive and inexperienced. I don't feel the naive programmer will do nearly as well. The CEO's reasoning is that the naive programmer can work full time and I can only do part time, so the less senior programmer could put more work into it. How can I convince him that 15 hours of my time is worth more than the other guy's 40?

• Does putting types/functions inside namespace make compiler's parsing work easy?

  - by iammilind

  Retaining the names inside namespace will make compiler work less stressful!? For example: // test.cpp #include</*iostream,vector,string,map*/> class vec { /* ... */ }; Take 2 scenarios of main(): // scenario-1 using namespace std; // comment this line for scenario-2 int main () { vec obj; } For scenario-1 where using namespace std;, several type names from namespace std will come into global scope. Thus compiler will have to check against vec if any of the type is colliding with it. If it does then generate error. In scenario-2 where there is no using namespace, compiler just have to check vec with std, because that's the only symbol in global scope. I am interested to know that, shouldn't it make the compiler little faster ?

• No startup sound

  - by Laci Bacsi

  Despite numerous attempt, and advise, this is what I applied. sudo cp /usr/share/sounds/ubuntu/stereo/* /usr/share/sounds/ Type this: cd /dev ls -l |less find 14, [0-...] This file for audio you can type cat /etc/passwc >/dev/dsp dsp if speaker device This is not a big deal but I'm an OCD person, so I would like that it works. An other issue is the screensaver, I can not watch movies. I understand that Ubuntu default settings are "Turned off start up sound, and 10 min screensaver auto" If I would be allowed to a suggestions, it is the followings: Is that so problematic to create a check box to check or un check this futures, just to be able to enjoy your product fully? Furthermore I'm reading a lot of similar issues on blogs... Annoying

• Whats steps can I suggest to achieve the best Geolocation Result [migrated]

  - by Matt

  We are using Geolocation (getCurrentPosition()) in a website to determine a users position when using our site from a mobile device. I want to write an article explaining how the user can obtain the best results. Am I correct in assuming: Enabling GPS will yield the best result when in rural areas (less buildings to obscure line of sight to the satelites) Enabling Wi-Fi will yield the best results when in urban areas (generally more Wi-Fi hotspots available) Is it true that Android phones have better results from silently harvesting Wi-Fi hotspot details? Any links to reference material on this are appreciated

• I've totally missed the point of distributed vcs [closed]

  - by NimChimpsky

  I thought the major benefit of it was that each developers code gets stored within each others repository. My impression was that each developer has their working directory, their own repository, and then a copy of the other developers repository. Removing the need for central server, as you have as many backups as you have developers/repositories Turns out this is nto the case, and your code is only backed up (somewhere other than locally) when you push, the same as a commit in subversions. I am bit disappointed ... hopefully I will be pleasantly surprised when it handles merges better and there are less conflicts ?

• Problem on application with asp in IIS 7.5 with oracle 11g

  - by Hichem

  We have an application developed with .Net on server 2008 R2 and IIS 7.5 wich is linked liked to oracle 11g on another server. Our problem is that we lose the service every two or three or more. The application stops and we have to restart IIS or the server to continue the job (the number of users is less then 50). We have no error message. Do you know anything to do to avoid this situation, something like: A parameter to put on asp pages A parameter to switch on or off on the server or on the database

• Alternatives to sql like databases

  - by user613326

  Well i was wondering these days computers usually have 2GB or 4GB memory I like to use some secure client server model, and well an sql database is likely candidate. On the other hand i only have about 8000 records, who will not frequently be read or written in total they would consume less then 16 Megabyte. And it made me wonder what would be good secure options in a windows environment to store the data work with it multi-client single server model, without using SQL or mysql Would for well such a small amount of data maybe other ideas better ? Because i like to keep maintenance as simple as possible (no administrators would need to know sql maintenance, as they dont know databases in my target environment) Maybe storing in xml files or.. something else. Just wonder how others would go if ease of administration is the main goal. Oh and it should be secure to, the client server data must be a bit secure (maybe NTLM files shares https or...etc)

• 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?

• Examples of "hidden" humor in programming books? [closed]

  - by Maglob

  Every now and then while reading programming books, I find more a less hidden jokes, passage of texts written in witty, tongue-in-cheek fashion, right there in middle of more serious text. These make me giggle and I remember these for years :) Such as The Java Programming Language, documentation about currentTimeMillis(): "The time is returned in a long, so it will not overflow until the year 292280995, which should suffice for most purposes. More sophisticated applications may require the Date class." Common Lisp The Language, 2nd ed, in index: "kludges, 1-971" What good "hidden" jokes you have come across while reading programming books?

• screen flickering

  - by lilicus

  When using some applications (LibreOffice, Chrome) it happens that screen flicker (just for a second, or even less than a second) or screen turns into black and then back to normal again... it all happens very fast (usually when clicking with the mouse)... for example, I was searching something in google chrome and list of possible results appeared - when I double click on the search text area (not list of possible results) screen flicker... or when changing border lines in LibreOffice Calc... I managed to create screen shot while using LibreOffice Calc. I am using Nvidia 313 drivers-updates on Ubuntu 13.04. What could be the problem?

• How do I implement URL rewriting in my .htaccess file?

  - by Alan

  I'd like to do some URL rewriting (Why? See this question.) so that instead of users seeing addresses like labouseur.com/course-compilers.html they can instead see and use simply labouseur.com/course-compilers (Even better, maybe I should restructure that so that it's courses/compilers.) I'm using a Linux-based shared hosting service for my website, so I do not have administrative control of the server, but I do have control over .htaccess. The references I've read online seemed less than clear to me, so I'm looking for a little clarity and advice here. Thanks!

• Can GJK be used with the same "direction finding method" every time?

  - by the_Seppi

  In my deliberations on GJK (after watching http://mollyrocket.com/849) I came up with the idea that it ins not neccessary to use different methods for getting the new direction in the doSimplex function. E.g. if the point A is closest to the origin, the video author uses the negative position vector AO as the direction in which the next point is searched. If an edge (with A as an endpoint) is closest, he creates a normal vector to this edge, lying in the plane the edge and AO form. If a face is the feature closest to the origin, he uses even another method (which I can't recite from memory right now) However, while thinking about the implementation of GJK in my current came, I noticed that the negative direction vector of the newest simplex point would always make a good direction vector. Of course, the next vertex found by the support function could form a simplex that less likely encases the origin, but I assume it would still work. Since I'm currently experiencing problems with my (yet unfinished) implementation, I wanted to ask whether this method of forming the direction vector is usable or not.

• ubuntu is becoming more unstable

  - by Michael Hennessey

  I find ubuntu extremely unstable with mouse freezes (that can be corrected with control key), constant Compiz crashes ( with ATI non proprietary drivers also), problems installing drivers ( why would I want a video driver that fails to play most games, with loss of function of so many games (BZ flag?? has been around for years with no problems). I get the feeling that there is so one in your dept who is intentionally making poor and unstable choices for less than altruistic reasons. Whatever happened has been worsening ever since Unity became a choice. I have tried Kubuntu, Mint, Lubuntu and several other variants with similar poor results. Be aware I have used Ubuntu for many years.

• 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?

• Is it normal for 12.04 to occupy almost 4GB? Also, related questions

  - by Grant

  I'm using a ASUS EeePC 901 and have some basic questions/issues. I installed 12.04 on the 4GB drive, selecting the option to erase it before doing so. Immediately after the installation I saw that Update Manager had over 100 updates pending. I attempted to install these, but was told that I had less than 100 MB remaining. Does the OS occupy all the other space? It seems that the best solution is to install 12.04 on the 16GB drive. Is this true? If I do this, what is the best way to erase the 4GB drive afterwards?

• Eclipse: AVD not appearing

  - by dgood1

  I have installed the ADT bundle for 32 bit. Using Ubuntu 12.04 Updated it a bit and installed the 2.3.3 Android version. I have Eclipse Indigo. When I use the Android Virtual Machine manager, after choosing a device, I get the progress bar after pressing "Start" but it disappears when it finishes and no virtual machine appears. No errors, too. I fear it would be a problem with my RAM (Laptop's = 512(or less). Allocated to Device = 128 - 300), having been told by a teacher that the emulator requires 2 GB RAM. I would like confirmation and/or solution.

• What is the benefit of the "download will begin shortly" page?

  - by Fammy

  I've noticed many websites that host files for downloads have an interstitial page between the download link/button and the actual start of the download. Terminology on the page may include "Your download will begin shortly. If it does not, try this direct link". What is the purpose of this page? It seems to draw away from the general experience of downloading a file. Is this beneficial for bookmarking? Less experienced users? Analytics?
