• Is there a limit on the number of threads that can be spawned simultaneously?

  - by georgesl

  Yesterday I came across this question: How can i call robocopy within a python script to bulk copy multiple folders?, and I though it might be a good exercise for multithreading. I though of spawning as many threads as files needed to be copied, each routine having an exception handling system to prevent the whole copying process from crashing (and log -using mutex on the log file - if there was an error). My question: Is there a limit on the number of thread you can spawn almost simultaneously? If yes, what is the limiting factor? My question is focused on PC desktop, but I welcome any answer on different hardware (embedded systems, calculus clusters, etc.).

• Ubuntu 12.04 Battery problem

  - by Rahul

  I have my laptop ( Dell Inspiron 14R) on dual boot with Ubuntu 12.04 and Windows 7. While using Windows 7, I used to get about 2.5-3 hours on battery fully charged (with my cellphone connected for 3g Internet). The battery is almost 2 years old. But in Ubuntu 12.04, I'm getting only about 1-1.5 hrs on battery. I tried installing jupiter, also tried some tweaks that were mentioned in the forums, like editing the grub file. But nothing seems to work. I am not sure if any app is draining the battery. The one application that I use always is firefox. It's always open. Is there any way I could get at least 2.5 hrs of battery time?

• Problems after upgrading from 10.04 to 12.04

  - by Paul D

  I upgraded to 12.04.1 from 10.04 recently and am running the Gnome Classic (no effects) desktop. I spent a couple of days tweaking the appearance and behaviour but there are two issues that I can't resolve. The mouse cursor frequently disappears, especially when scrolling through web pages or hovering over links/icons with tooltips. Moving the mouse brings the pointer back but it vanishes again almost immediately. Note I don't have unclutter or Parallels installed. The screen no longer fades to black when left idle for too long - it just cuts out. Bad news when watching content online. Any tips greatly appreciated. Cheers...

• How can I reinstall GRUB Bootloader on MBR after installing Kubuntu?

  - by Agnes

  I installed Ubuntu, but then installed Kubuntu over it (formated Ubuntu Partition) because Ubuntu is not compatible with almost any hardware on my PC. Problem is I'm stuck with an old GRUB that says Ubuntu in the options because in my attempts to make it compatible with my hardware I got an old Grub with an image with an Earth that says Debian. How can I replace the GRUB with the one Kubuntu is supposed to install. I don't want to modify just the text, or the command to install on /sdaX, I want to actually re-write the MBR with the latest grub (reinstall the bootloader). Thanks.

• Intel GMA 4500M screen resolution problem

  - by I Heart Ubuntu

  I was previously running 10.10 on my Acer Aspire laptop. It has Intel GMA 4500M integrated graphics and worked just fine. Great display, sharp, crisp, etc. I decided to do a fresh install of 11.10 Oneiric and now am having problems. Originally I was getting the dreaded blank screen where the brightness was turned almost completely off. Some searching pulled up several easy fixes (editing GRUB). Right now I am still having one issue. The screen resolution is stuck at a max of 1024x768 giving me a distorted screen. Is there any way to fix this issue? I've Googled, searched Ask Ubuntu and also spent time on the forums looking for a solution. Thus far, nothing. Apparently, was and still is a concern in Natty? Any help would be greatly appreciated.

• What most games would benefit from having

  - by Phil

  I think I've seen "questions" like this on stackoverflow but sorry if I'm overstepping any bounds. Inspired by my recent question and all the nice answers (Checklist for finished game?) I think every gamedev out there has something he/she thinks that almost every game should have. That knowledge is welcome here! So this is probably going to be an inspirational subjective list of some sorts and the point is that anyone reading this question will see a point or two that they've overlooked in their own development and might benefit from adding. I think a good example might be: "some sort of manual or help section. Of course it should be proportional to how advanced the game is. Some users won't need it and won't go looking for it but the other ones that do will become very frustrated if they can't remember how to do something specific that should be in the manual". A bad example might be "good gameplay". Of course every game benefits from this but the answer is not very helpful.

• When to learn the command line version of a programming tool?

  - by explorest

  Almost every programming tool has a command line version; many of which also have a gui version. It takes a lot of time and memorization effort to learn the different commands and various options/switches of the command line version. So I have a couple of questions (which are not necessarily mutually exclusive): 1) When would you bother learning/memorizing the commands in the command line version of a tool which also comes in a gui version ? 2) What tools should I learn the command line version of ? .... compilers ? version control system ? etc, etc

• 404 code/header for search engines, on removed user content?

  - by mowgli

  I just got an email, from a former user on my website He was complaining that Google still shows the contact page he created on my site, even though he deleted it a month ago This is the first time in many years anyone requests this I told him, that it's almost entirely up to Google what content it wants to keep/show and for how long. If it's deleted on the site, I can't do much, other than request a re-visit from the googlebot The user-page already now says something like "Not found. The user has removed the content" TL;DR: But the question is: Should I generally add a 404 header (or other) for dynamic user content that has been removed from the site? Or could this hurt the site (SEO)?

• How do I run Microsoft Explorer 8 plus on Ubuntu?

  - by user169487

  First off, you should know I'm a Ubuntu newbie who has become passionate since my strangely low-priced Dell computer showed up with Ubuntu loaded on it and it could do almost everything I need from a computer. But now I've got a problem. I know, it's like asking how to use a cassette player on your computer, but in South Korea EVERY website is made to work with exclusively on MS Explorer PLUS Active X, which Microsoft finally killed with 9. Hence, I have to use 8, as there are some Korean sites I need to access for searching, banking, etc. So I see that the way to go is to load PlayOnLinux, but then I it tells me to delete these. Do I really have to do that? Should I just hit "Install Anyway"? Or would that be just asking for trouble?

• T-SQL Tuesday: What kind of Bookmark are you using?

  - by Kalen Delaney

  I’m glad there is no minimum length requirement for T-SQL Tuesday blog posts , because this one will be short. I was in the classroom for almost 11 hours today, and I need to be back tomorrow morning at 7:30. Way long ago, back in SQL 2000 (or was it earlier?) when a query indicated that SQL Server was going to use a nonclustered index to get row pointers, and then look up those rows in the underlying table, the plan just had a very linear look to it. The operator that indicated going from the nonclustered...(read more)

• Where does UBB store its settings?

  - by pjmorse

  We're moving a UBB forum from one host to another. (This is temporary; we're going to replace the forum eventually, but moving hosts has a higher priority.) We don't have a lot of experience with UBB, so we're feeling our way along in the dark. We got the UBB code installed on the new host, and we've done a dry-run database export from the original site to the new site. However, almost everything set in UBB's Control Panel section didn't come with the database export. If UBB doesn't store this data in the database, where is it stored? And if it is in the database, why would it not show up in a new forum when the database is imported? Did we somehow miss a table?

• 2D Topdown Shooter Mouse Movement

  - by Jarmo

  I'm trying to make a topdown 2D space game for my school project. I'm almost done but I just want to add a few little things to make the game more fun to play. if (keystate.IsKeyDown(Keys.W)) { vPlayerPos += Vector2.Normalize(new Vector2(Mouse.GetState().X - vPlayerPos.X, Mouse.GetState().Y - vPlayerPos.Y)) * 3; rPlayer.X = (int)vPlayerPos.X; rPlayer.Y = (int)vPlayerPos.Y; } if (keystate.IsKeyDown(Keys.S)) { vPlayerPos += Vector2.Normalize(new Vector2(Mouse.GetState().X - vPlayerPos.X, Mouse.GetState().Y - vPlayerPos.Y)) * -3; rPlayer.X = (int)vPlayerPos.X; rPlayer.Y = (int)vPlayerPos.Y; } This is what i use to move towards and away from my mouse crossair. I tried to make a somewhat similar function to make it strafe with "A" and "D". But for some reason I just couldn't get it done. Any thoughts?

• Do navigation menu links negatively impact SEO for pages' content?

  - by Rodolfo

  I've always had my doubts about navigation menus effect on SEO. You know, the vertical menus on the top that show in every page in the site linking to main sections and subsections. My issue is that if not done dynamically (i.e. after page is loaded or something), from a search engine's point of view it probably looks like a whole bunch of links in the beginning of the page, and links that probably have nothing to do with the page being analyzed, so it's probably not only confusing it, but also giving link 'juice' to the wrong pages or reducing its value. When I've asked SEO people about this, I usually get a "Google is smart, they'll recognize it as a menu and ignore it" response, but I'm not convinced (and the 'Google is smart' argument sounds almost like religion discussion to me). So does it affect SEO negatively or not? Are there any official posts on this topic?

• Failed GRUB after 10.04 to 12.04 upgrade in system with LVM

  - by Vagelis L

  I am using Ubuntu Server as a SMB server at work and two days ago I have tried to upgrade it to 12.04. After reboot, I got this grub_xput missing grub rescue> and all attempts to start from this prompt failed (missing components, although grub directory is normally set as prefix). My system sits and boots on an LVM (soft raid-5). I have read almost all posts in many forums, tried grub rescue, boot-repair, ubuntu-secure-remix with boot-repair but without positive result. This is the log of my last (and best so far) attempt to fix this system. Any suggestions? Please help.

• Eclipse Juno (4.2.1) crashes frequently after upgrading to Ubuntu12.10 from 12.04 (both 64bits)?

  - by Amit

  I was using eclipse Juno (ver 4.2.1) on my 64bit ubuntu 12.04 for almost a month or more. It was working perfectly and I really enjoyed working on it. However two days back I upgraded my machine to Ubuntu 12.10 since than eclipse Juno is working strangely irritating. It crashes frequently. I even removed the old installation completely and reinstalled everything (ADT, Subclipse, CDT etc.) What could be the possible reason behind this ? How I solve it ?

• Slow writing HDD speed, Ubuntu 12.04 64-bit, Thinkpad T520i

  - by pyc

  It seems that (but I'm not completely sure), that when I'm copying files from gigabit network to HDD, I can't use full potential of the network which in my case is about 60 MB/s, because HDD writing is so slow like lower than 10 MB/s, and also it's slowing down the whole system which becomes pretty much unresponsive, almost impossible to work with. Copying files to samba share residing at Ubuntu machine, connected to share from Windows 7, I'm completely sure my network equipment is OK, and there's no CPU intensive process on Ubuntu except smbd getting about 10-20% from time to time which I think is OK. Something here is burried deep I think, maybe even in kernel. Already tried to switch from AHCI to compatibility mode, and turning acpi on and off - nothing helped. So it's like HDD buffer is full and emptying slowly while machine is sluggish, load is about 3 to 4. Somebody experienced the similar problems? Some help on troubleshooting process and identifying the cause would be helpful too :) Thanks!

• Sites with overlapping code-bases. Developing multiple sites with little changes

  - by Web Developer

  I have to develop 3 different sites video.com for hosting video audio.com for hosting audio docs.com for hosting docs. domain names for example only Almost 80% of the functionality is the same for all the three, with remaining 20% being completely different features... How do I handle this? How does sites like SO handle this? I am developing this in YII framework and was thinking of having these different features as modules but in this case the menu/code links in html code can become difficult.

• Are HTTP requests cached? [closed]

  - by nischayn22

  Many HTTP requests are sent repeatedly by browsers on almost every page load, such as requesting the jQuery .js file etc. Since these are already used on too many sites doesn't modern browsers keep a cache for this? I am thinking of a system where the browser has a cached copy of the .js file used very very frequently. On a new request for the .js file, it sends the server a request for a hash of the .js file (provided the server can reply to that) and compares the returned hash with the cached copy's hash... rest is intuitive.

• Nautilus is extremely slow

  - by Maxim

  I am on Ubuntu 11.04. And Nautilus is very slow. It opens directories for 3-5 seconds even if a directory contains just a few small files. Even selecting of a file or directory with narrow keys is extremely slow and it rises my CPU usage up to 100%. It makes it almost unusable. But I noticed that if I start my nautilus as superuser: $ gksu nautilus then it works just fine. It is fast and responsive. So what can I do to fix this? Any help is really appreciated.

• How is your working time distributed between coding and thinking?

  - by mojuba

  ...in percentage. For example 60/40 or 90/10 or 100/0. My hypothesis is that the bigger the proportion of time you spend thinking the smaller your code can be as a result (and the less time will be needed to write it down). Think more, write less, in other words. Do you think it is true? As a side note, I think in typical software companies thinking is not part of the culture anyway: you are usually supposed to be sitting there at your computer typing something. You will almost definitely be noticed by your managers if you wander about with a blank look thinking over your next steps with your code. Too bad.

• All windows decorations disappear after I maximize any window

  - by korda

  When I maximize some of the windows all decorations disappear (by all, I mean on all windows)... Is that common issue on Unity or I'm just unlucky to have some prone to that bug configuration? Anyone have idea how to fix this? It won't fix after unmaximize. It seems like maximazing window simply crashes window decorator. Decoration isn't displayed for all existing windows and any new ones. Only way I found to fix this is to run compiz --replace (but this ruins current windows placement - all windows end up on same desktop). It happens almost every time I maximize window.

• Is it a good idea to make a game for one aspect ratio and arbitrary screen resolution?

  - by Mimars

  After several very small games I have decided to make something more standalone (2D) and playable. However, I have met the problem of every game that is going to be played in more screen resolutions. Basically, after some research I see that there are several solutions. This seems to be the simplest one: Let's say I define a constant aspect ratio for the game (16:9) and the whole game will be created for a resolution 1680 x 1050. The game will be rendered in this resolution and then I will be able to scale the render to match the player's display resolution. Therefore the game might be playable on almost any resolution, while it would keep the aspect ratio. So, if the game was run on 4:3 display, the top and the bottom of the display would be filled with black color. It seems easy, but my question is - Is this a good approach for a simple game? The game will be simple, but I want to maintain high quality.

• Programming a trading strategy

  - by Rob

  Excuse me if I'm not descriptive enough, as I do not have much of a background when it comes to these things: How would I go about coding a primitive trading strategy and link it to some sort of artificial trading environment? Where do I start, and what are some other essential questions I should be asking? I am interested more in doing this because it interests me than making returns. Ideally it utilizes random/historical market data and doesn't actually execute any real trades. My background: I'm almost done my undergrad degree in computer science, and have had intro finance and economic courses. Familiar mostly with C and Java.

• Adding a short delay between bullets

  - by Sun

  I'm having some trouble simulating bullets in my 2D shooter. I want similar mechanics to Megaman, where the user can hold down the shoot button and a continues stream of bullets are fired but with a slight delay. Currently, when the user fires a bullet in my game a get an almost laser like effect. Below is a screen shot of some bullets being fired while running and jumping. In my update method I have the following: if(gc.getInput().isKeyDown(Input.KEY_SPACE) ){ bullets.add(new Bullet(player.getPos().getX() + 30,player.getPos().getY() + 17)); } Then I simply iterate through the array list increasing its x value on each update. Moreover, pressing the shoot button (Space bar) creates multiple bullets instead of just creating one even though I am adding only one new bullet to my array list. What would be the best way to solve this problem?
