• Unable to install applications (Oneiric)

  - by yayu

  When I use the software center to install something, I get the error: An unhandlable error occured There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks on using the command line: $sudo apt-get install <something> E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. I am unable to install anything. How do we fix this?

• Windows 2003 to log on no matter how it turned off

  - by Arya

  I have a windows server 2003, which I use Teamviewer to connect to. When there is a power failure, and the computer restarts, it will not load Teamviewer. It gets stuck on a screen which asks why the computer was turned off. There is no keyboard or mouse connected to the server and I need Teamviewer to open every time. I don't want the screen asking why it was turned off to show up ever. I turned off Shutdown Event Tracker by doing the following: Open gpedit.msc Computer Configuration Administrative Templates System click Display Shutdown Event Tracker and then selected the disable radio button. Is this enough to prevent that screen to show up again? or is there anything else I need to change?

• Why does the player fall down when in between platforms? Tile based platformer

  - by inzombiak

  I've been working on a 2D platformer and have gotten the collision working, except for one tiny problem. My games a tile based platformer and whenever the player is in between two tiles, he falls down. Here is my code, it's fire off using an ENTER_FRAME event. It's only for collision from the bottom for now. var i:int; var j:int; var platform:Platform; var playerX:int = player.x/20; var playerY:int = player.y/20; var xLoopStart:int = (player.x - player.width)/20; var yLoopStart:int = (player.y - player.height)/20; var xLoopEnd:int = (player.x + player.width)/20; var yLoopEnd:int = (player.y + player.height)/20; var vy:Number = player.vy/20; var hitDirection:String; for(i = yLoopStart; i <= yLoopEnd; i++) { for(j = xLoopStart; j <= xLoopStart; j++) { if(platforms[i*36 + j] != null && platforms[i*36 + j] != 0) { platform = platforms[i*36 + j]; if(player.hitTestObject(platform) && i >= playerY) { hitDirection = "bottom"; } } } } This isn't the final version, going to replace hitTest with something more reliable , but this is an interesting problem and I'd like to know whats happening. Is my code just slow? Would firing off the code with a TIMER event fix it? Any information would be great.

• Where is the time spent?

  - by 280Z28

  Game development is a large process. In your experience, how are the total hours for releasing a game divided over the following major areas. I believe this is useful because few people (none?) are really good at all the areas, so this helps me balance the cost of items I'm not so good at when estimating the complexity of creating a game. Modeling and raw asset creation (textures, audio) Level design Gameplay design Programming Testing Marketing

• Server to server replication and CPU and 32k\ corrupt doc

  - by nick wall

  Summary: if database contains a doc with 32K issue or corrupt, on server to server replication it causes marked increase in CPU in nserver.exe task, which effectively causes our server(s) to slow right down. We have a 5 server cluster (1 "hub" and 4 HTTP servers accessed via reverse proxy and SSO for load balancing and redundancy). All are physically located next to each other on network, they don't have dedicated network\ ports for cluster or replication. I realise IBM recommendation is dedicated port for cluster. Cluster queues are in tolerance and under heavy application user load, i.e. the maximum number of documents are being created, edited, deleted, the replication times between servers are negligible. Normally, all is well. Of the servers in the cluster, 1 is considered the "hub", and imitates a PUSH-PULL replication with it's cluster mates every 60mins, so that the replication load is taken by the hub and not cluster mates. The problem we have: every now and then we get a slow replication time from the hub to a cluster mate, sometimes up to 30mins. This maxes out the nserver.exe task on the "cluster mate" which causes it to respond to http requests very slowly. In the past, we have found that if a corrupt document is in the DB, it can have this affect, but on those occasions, the server log will show the corrupt doc noteId, we run fixup, all well. But we are not now seeing any record of corrupt docs. What we have noticed is if a doc with the 32K issue is present, the same thing can happen. Our only solution in that case is to run a : fixup mydb.nsf -V, which shows it is purging a 32K doc. Luckily we run a reverse proxy, so we can shut HTTP servers down without users noticing, but users do notice when a server has the problem! Has anyone else seen this occur? I have set up DDM event handlers for many of the replication events. I have set the replication time out limit to 5 mins (the max we usually see under full user load is 0.1min), to prevent it rep'ing for 30mins as before. This ia a temporary work around. Does anyone know of a DDM event to trap the 32K issue? we could at least then send alert. Regarding 32K issue: this prob needs another thread, but we are finding this relatively hard to find the source of the issue as the 32K event is fairly rare. Our app is fairly complex, interacting with various other external web services, with 2 way data transfer. But if we do encounter a 32K doc, we can't look at field properties, so we can't work out which field has issue which would give us a clue as to which process is culprit. As above, we run a fixup -V. Any help\ comments on this would be gratefully received.

• What should a Python developer know while learning Ruby?

  - by C J

  I have been a Python programmer for about 18 months, consisting of one internship and a few side projects, and I consider myself pretty comfortable in the language. However, there seems to be a lot of attention on Ruby in the programming field, but not a lot on Python anymore. So in learning Ruby, are there going to be Pythonic things that are just bad practices in Ruby? What should I watch out for, and what should I avoid?

• Pre-rendered fire. Where to find? [on hold]

  - by Vladivarius

  I'm studying game programming. I haven't yet implemented generated fire rendering in my ,,engine'' so I'm looking for some pre-rendered fire textures for early demo-scenes, but they seems strangely difficult to find. I'm currently using some that I ripped from DMC but I want to try out different ones. Does anyone know where to find these? Software that could generate them would also be ok. Thanks :)

• When creating a library for a simple program, what must I do to protect others from its lack of thread safety?

  - by DeveloperDon

  When creating a library for a simple program, is it more cost effective to make it thread safe or is there a way to detect the program's use in a multithreaded program and ASSERT() or otherwise determine (preferably at compile or link time) that it may create problems. Related help for this question would be automated tool support for finding potential problems with thread safety, programming language features that enforce it,

• 3D models overlapping each other

  - by Auren

  I have a problem at the moment when I draw some models to teach me more about 3D game programming. The models at the moment overlaps each other from some angles witch makes sense since the game at the moment draws from left to right, line after line. However my question is: Is there any easy escape from this issue or is there any way that you could draw the in-game world from the players position? I would really appreciate if someone could give me some answers on this.

• How to change the icon of an aplicatication at the LxPanel on Lubuntu?

• Why the Ubuntu App Developer website is not showing content about development for desktop?

  - by Zignd

  Looks like they removed every content that is not related with development for desktop. For example when you click in "Get Started" tab there is only information about the Ubuntu Touch and its SDK, when you click on "Resources" tab and then on "Programming languages" you only see C++, JavaScript and QML (no Python, Java, Mono, etc). You also can't find any information about Quickly, try clicking on "Quicky" at "Resources" in the website bottom and you will see a "Page not found" error. Is the site under maintenance or something else?

• Employer admits that its developers are underpaid and undervalued. Time to part ways?

  - by Psionic

  My employer recently posted an opening for a C# Developer with 3-5 years of experience. The requirements and expectations for the position were fair, up until the criteria for salary determination. It was stated clearly that compensation would depend ONLY on experience with C#, and that years of programming experience with other languages & frameworks would be considered irrelevant and not factored in. I brought up my concern with HR that good candidates would see this as a red flag and steer away. I attempted to explain that software development is about much more than specific languages, and that paying someone for their experience in a single language is a very shortsighted approach to hiring good developers (I'm telling this to the HR dept of a software company). The response: "We are tired of wasting time interviewing developers who expect 'big salaries' because they have lots of additional programming experience in languages other than what we require." The #1 issue here is that 'big salaries' = Market Rate. After some serious discussion, they essentially admitted that nobody at the company is paid near market rate for their skills, and there's nothing that can be done about it. The C-suite has the mentality that employees should only be paid for skills proven over years under their watch. Entry-level developers are picked up for less than $38K and may reach 50K after 3 years, which I'm assuming is around what they plan on offering candidates for the C# position. Another interesting discovery (not as relevant) - people 'promoted' to higher responsibilities do not get raises. The 'promotion' is considered an adjustment of the individuals' roles to better suit their 'strengths', which is what they're already being paid for. After hearing these hard truths straight from HR, I would assume that most people who are looking out for themselves would quickly begin searching for a new employer that has a better idea of what they're doing in the industry (this company fails in many other ways, but I don't want to write a book). Here is my dilemma however: This is the first official software development position I've held, for barely 1 year now. My previous position of 3 years was with a very small company where I performed many duties, among them software development (not in my official job description, but I tried very hard to make it so). I've identified local openings that I'm currently qualified for, most paying at least 50% more than I'm getting now. Question is, is it too soon for a jump? I am getting valuable experience in my current position, with no shortage of exciting projects. The work environment is very comfortable, and I'm told by many that I'm in the spotlight of the C-level guys for the stuff that I've been able to accomplish during my short time (for what that's worth). However, there is a clear opportunity cost to staying, knowing now with certainty that I will have to wait 3-5 years only to be capped at what I could potentially be earning elsewhere this year. I am also aware that 'job hopper' is a dangerous label to have, regardless of the reasons.

• Best approach for tracking dependent state

  - by Pace

  Let's pretend I work on a project tracking application. The application is a database backed, server hosted, web application. In this application there are Projects which have many Activities which have many Tasks. A Task has two date fields an originalDueDate and a projectedDueDate. In addition, there are dynamic fields on the Activities and the Projects which indicate whether the Activity or Project is behind schedule based on the projected due dates of the child tasks and various other variables such as remaining buffer time, etc. There are a number of things that can cause the projectedDueDate to change. For example, an employee working on the project may (via a server request) enter in a shipping delay. Alternatively, a site may (via a server request) enter in an unexpected closure. When any of these things occur I need to not only update the projectedDueDate of the Task but also trigger the corresponding Project and Activity to update as well. What is the best way to do this? I've thought of the observer pattern but I don't keep a single copy of all these objects in memory. When a request comes in, I query the Task in from the database, at that point there is no associated Activity in memory that would be a listener. I could remove the ability to query for Tasks and force the application to query first by Project, then by Activity (in context of Project), then by task (in context of Activity) adding the observer relationships at each step but I'm not sure if that is the best way. I could setup a database event listening system so when a Task modified event is dispatched I have a handler which queries for the Activity at that point. I could simply setup a two-way relationship between Task and Activity so that the Task knows about the parent Activity and when the Task updates his state the Task grabs his parent and updates state. Right now I'm stuck considering all the options and am wondering if any single approach (doesn't have to be a listed approach) is jumping out at others as the best approach.

• Dropping multiple objects using an array in Actionscript?

  - by Eratosthenes

  I'm trying to get these fireBalls to drop more often, I'm not sure if I'm using Math.random correctly. Also, for some reason I'm getting a null reference because I think the fireBalls array waits for one to leave the stage before dropping another one? This is the relevant code: var sun:Sun=new Sun var fireBalls:Array=new Array() var left:Boolean; function onEnterFrame(event:Event){ if (left) { sun.x = sun.x - 15; }else{ sun.x = sun.x + 15; } if (fireBalls.length>0&&fireBalls[0].y>stage.stageHeight){ // Fireballs exit stage removeChild(fireBalls[0]); fireBalls.shift(); } for (var j:int=0; j<fireBalls.length; j++){ fireBalls[j].y=fireBalls[j].y+15; if (fireBalls[j].y>stage.stageHeight-fireBall.width/2){ } } if (Math.random()<.2){ // Fireballs shooting from Sun var fireBall:FireBall=new FireBall; fireBall.x=sun.x; addChild(fireBall); fireBalls.push(fireBall); } }

• What are possible reasons why a calendar entry in OWA is at a different time than in Outlook?

  - by Ken Pespisa

  We have two Exchange 2003 servers, our primary server and a front-end server that hosts Outlook Web Access (OWA). When I open my boss' calendar via Outlook 2007 (from my Outlook client as well as hers) I see the event scheduled for 10:30 am. When I open her calendar via Outlook Web Access, the same event is scheduled for 4:30 am. I don't understand Exchange well-enough to imagine how this is possible. If you have any ideas why this could be happening, I greatly appreciate it. I'd also very much appreciate any insight you have to how this could be possible. There must be some cached data on the front-end server that causes the calendar entry to appear at a different time, I suppose. Any insight into how Exchange manages that cache and where I could look for an issue would be very helpful. Thank you!

• Recommended readings for a sofware construction mini-course [on hold]

  - by Aivar

  I'm going to organize a mini-course for CS students who have completed CS1 (Python) and CS2 (Java). I'd like to show them more principled approach to programming practice and design, something along the lines of McConnel's Code Complete. If I had enough copies of Code Complete, I would assign some readings from that book. Can you recommend some freely available material (books, blog posts, articles, essays) for such a course? (I'd prefer to avoid topics specific to OOP and focus on more universal principles.)
