• Client Side Prediction

  - by user13842

  I have a question regarding Client Side prediction. Ive tried to search topics about my specific problem but couldn't find anything which really answered my problem. Most tutorials and explanations assume that the Client sends messages like "Move my player up by 1 Position", but what if i send messages like "Set my player's velocity to x"? Since it's hard to explain with text, i made a graphic explaining my problem. The main problem is, that the player sets his own velocity, due to Client Side Prediction, earlier than the Server. So if 2 different velocities overlap, the Server would get out of sync. How can i tackle that problem? Thanks a lot. Graphic: http://img27.imageshack.us/img27/6083/clientpred.png (Ignore the 5.5cm)

• What are the challenges and benefits of writing games with a functional language?

  - by McMuttons

  While I know that functional languages aren't the most commonly used for game writing, there are a lot of benefits associate with them that seem like they would be interesting in any programming context. Especially the ease of parallelization I would think could be very useful as focus is moving toward more and more processors. Also, with F# as a new member of the .NET family, it can be used directly with XNA, for example, which lowers the threshold quite a bit, as opposed to going with LISP, Haskell, Erlang, etc. If anyone has experience writing games with functional code, what has turned out to be the positives and negatives? What was it suited for, what not? Edit: Finding it hard to decide that there's a single good answer for this, so it's probably better suited as a community wiki post.

• LXDE will not suspend when laptop lid is closed, and will die when woken up

  - by user46061

  I am not an experienced Linux user, although I have been using Ubuntu occassionally some time already. ( Since Feisty Fawn probably? ). Now I installed Ubuntu 11.10 and it is nice ( well, after I installed LXDE, Unity sucks and I didn't really like gnome-fallback-session ), but it has one problem: After being suspended, when I wake my computer up, it starts up and in about 5 seconds it dies. Like a normal shutdown. Then, when I start it again, the screen stays blank, so I have to hard-turn it off - only then, when I turn it on, it works. It is an MSI laptop, about 3-4 years old. The second problem is: After installing LXDE, when I close the laptop lid, it does not suspend. I can only suspend using the shutdown menu - and the waking up problem remains. Many thanks for your time and advice guys.

• Why do so many people dislike C++?

  - by General K

  Beginners and professional, on blogs, in forums and chatrooms - people say it everywhere: C++ oh dear god no The short form of the question: For what reason is C++ so widely disliked and people are horrified by the imagination of using it for some project? I have been using a lot of different languages, including C++ by now, and I can only say that I really like it. I'm far more horrified by Delphi than by C++. Actually, I find it's an almost perfect, compiled language! I've been doing a lot of different projects in C++ as well, ranging from 3D video games to webservers and emulators for old video game consoles. And I still do not see the problem everyone else seems to have with it! It was hard for me to get into it of course, as it is quite complex and has a lot of depth, but after that it's simply great.

• Ubuntu on low powered laptop

  - by zkent

  First off, I am new to Ubuntu. I come from a Windows background (DOS before that) and am loving it so far. I installed it on an older Dell laptop that I wanted to get another year out of. I set this machine up primarily as a LAMP development machine for a project I am working on. The machine is a Vostro 1500 and it has 4GB RAM (maxed) and an upgraded hard drive. I can't watch YouTube videos for long before it starts to overheat and start acting sporadic. I can live without YouTube but every so often the application switching (alt-tab) gets slower and begins not showing all applications and the Dash home quits displaying properly. I am sure I am asking a lot of this old machine. What I really want to know is: are there any settings in Ubuntu that allow me to lower the graphic effects (fade-ins, transparencies, fancy transitions, etc) that would be less taxing on the video card?

• How can I download and make an Ubuntu CD from inside a booted Ubuntu Live CD?

  - by miguel

  I have an older laptop with a ADA hard disk I can't really buy a new one so I want to erase Windows Vista on my computer and only have Ubuntu so that I can have more space. How do I make it go directly to my blank CD? My Windows Vista is messed up and I can't even get into it. I want to download the new version of Ubuntu while in Ubuntu. I downloaded it but it didn't go directly to the blank CD. I tried to copy all of Ubuntu onto the CD once it was downloaded but it says there was an error while copying. What should I do?

• Your favorite LiveCD

  - by sova

  Perhaps this is a question better suited for linux.se but since I have servers on all environments I was wondering what your favorite LiveCD is. Wiki defines this, for those unfamiliar, as a CD or DVD containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive. Live USB flash drives are similar to live CDs, but often have the added functionality of automatically and transparently writing changes back to their bootable medium. I tend to stick with Knoppix, and today I have to register the machine on the network before I can get any of my utilities running via IP. Any suggestions?

• System doesn't boot due to a "[drm: drm_crtc_helper_set_config] * error * "

  - by Albin

  I have a problem with the new Ubuntu 12.10. It finished installing correctly, but when I restart my computer an error message appears: [15.854296] [drm: drm_crtc_helper_set_config] * error * failed to set mode on [CRTC: 10] * checking battery state [17.814209] [drm: drm_crtc_helper_set_config] * error * failed to set mode on [CRTC: 10] and that screen does not advance. I also tried booting from the recovery mode and it starts, but it's too slow loading windows and also shows me a window with an error message: Sorry Ubuntu 12.10 has experienced an internal error More Details: Executable path /usr/bin/xorg I have used Ubuntu since the 2008 version and never had this problem. I hope you can help me. Computer Specs: compaq sr2015la AMD sempron 2Gb. RAM 80Gb Hard Drive Translated from the original Spanish

• How can you monitor internet download usage?

  - by dv3500ea

  Some broadband providers impose a monthly download limit, charging extra if you go over. It is also quite easy to exceed some of the lower limits just by installing/updating packages and 'normal' browsing (which to me includes streaming TV programs and movies). This means that you need to limit the amount you use the internet, yet it is hard to know when. The System Monitor helps a bit with this by giving a total received/total sent in the networking section of the Resources tab. However, this is reset every reboot. It would be good if there was a way to have a monthly total received so you can know how close you are to exceeding your limit and maybe even be given warnings if it looks like you are going to exceed the limits. Does anyone know of a way to achieve this?

• Blank Screen ... No Bios Loading Screen Either

  - by SwissStar

  I don't even know how long it's been but I had given up. until now. My screen does not come on AT ALL, not even and the Bios loading screen. I have to connect it to my TV in order to see. But there's one thing that has always started it back up, and that is by running a hard ware Diagnostics * Provided by DELL* . It is definitely has something to do with Ubuntu. I know that for sure, because I remember running an update and BAM . That was it for the screen. How could I restore my screen back to Life ? I have a Nvidia Graphics Card.

• Programers first day at work [closed]

  - by peraueb8921

  Next week I am getting my first job as a programmer in a well known company. I have worked in other companies before, but mostly in IT department. As you can understand, I am very determined to succeed in there. I have found some related articles in the Web, but I am not even sure they are written from developers. So I am asking you, to tell us about what will you do in another way if you could "reverse" the time, and what can I do to succeed. Of course "work hard" is one of them but what about book/article reading, certifications, good practises to make good impression to my team leader or whatever else you think would help? I know that it maybe fit better at wordplace.stackexchange.com, but this is a programmer oriented post and can only be answered by experienced programmers. Thank you.

• Installing Ubuntu before or after upgrading from Vista to Win 7?

  - by amh

  I just got a new SSD hard drive for my thinkpad laptop. I just installed Vista with the factory CDs. On my old OS, my main OS was Ubuntu but I do want to keep Windows on a separate partition as a dual booth system. I definitely want to upgrade to Win 7 though and I will get it in a few days. My question is: should I install Ubuntu now and then upgrade to Win 7 in a few days? or is that going to mess up with the grub (or something else)? If that is the case, then I'd rather wait to install Ubuntu until after I upgrade to Vista. P.S. I know that probably any kind of mess done by the Win upgrade could be fixed, but I just want to avoid wasting time.

• Algorithm for determining grid based on variably sized "blocks"?

  - by Lite Byte

  I'm trying to convert a set of "blocks" in to a grid-like layout. The blocks have a width of either 25%, 33%, 50%, 66%, or 75% of their container and each row of the grid should try to fit as many blocks as possible, up to a total width of 100%. I've discovered that trying to do this while leaving no remaining blocks in the original set is very hard. Eventually, I think my solution will be to upgrade/downgrade various block sizes (based on their priority or something) so they all fit in to a row. Either case, before I do that, I thought I'd check if someone has some code (or a paper) demonstrating a solution to this problem already? And bonus points if the solution incorporates varying block heights in to its calculations :) Thanks!

• Managing a remote ubuntu server

  - by erdomester

  I hire an Ubuntu server which I access remotely and I purchased a domain for my webpage. I am totally new to this server thing and to Ubuntu as well. What applications should I install on the server? I need to transfer files to the server, I guess I would use FileZilla the same way I use it to upload files to my free website. But to have a username and password should I install an ftp server and create a user on Ubuntu? My website will send automated messages to users, so do I need to install a mail server as well? What other software should I install on the server apart from a firewall and an anti-virus? Should I partition the hard drive (3TB) and how? How partitions should I create and in what size for what applications? Btw I use Windows 7 on my computer, so I am basically a windows user.

• Ubuntu 12.04 Hangs with Software Center open then opening Dash Home

  - by Josea

  I have a Dell D610 - Intel graphics - 1 Gig RAM. I have test the hard drive and RAM and both are fine. When I open Software Center, then Dash home my system locks up. The mouse cursor moves but is unresponsive if I try to right or left click anything. The keyboard is totally unresponsive and I have to hold the power button to power off! I have reinstalled from CD, did all updates but the issue persists. I tried using the track pad only, and I plugged in an external mouse also but no change. Everything else works great ! I am sick of running Vista and have no love for Metro! Thanks for any suggestions, on a scale of 1 to 10 (Newbie - Expert) I am about 3

• Microsoft Secret Event: New Tablet Unveiling?

  If you read the headline, you know what everyone thinks it will be: a new tablet computer, that Microsoft will manufacture from beginning to end. Apparently, the company believes it will be better able to compete against Apple if it controls both the hardware and the software. But why choose this location for the announcement? Wired thinks it makes sense if the tablet features Xbox live streaming. That would turn the humble device into something of a media machine. Speaking of the device itself, what kind of specs will this hypothetical tablet have? It's hard to say. Microsoft boasts software...

• How to Remove Soft Blocks Permanently in Ubuntu 12.04 LTS?

  - by BBN

  I am using Ubuntu 12.04 LTS on an Asus Eee PC 1000HA. Since I upgraded to 12.04, I have had problems connecting to wifi. When I fly, I need to disable wifi. When I try to reconnect, the "enable networking" option is no longer available. If I type in the terminal "rfkill list", the following shows up: 0: eeepc-wlan: Wireless LAN Soft blocked: yes Hard blocked: no If I type "rfkill unblock all", "enable networking" will become available and I am able to connect to wifi. How can I permanently remove this annoying Soft Block? I don't want to be typing up two lines of code. Any help would be greatly appreciated.

• 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?

• Wireless will not work in fresh ubuntu 12.04 lts installation

  - by Taake Manning

  I did a fresh Ubuntu 12.04 install on my Sony Vaio laptop, which worked perfectly with 10.04. Now my wireless won't work. I have read just about every Q&A on the subject and I have tried different solutions, including the official troubleshooting guides. My laptop is equipped with a Intel 5100 wireless device. Ubuntu recognizes the device and it's status is given as connected in nm-tool. I can ping the gateway, my own IP number and localhost. Rfkill shows no soft or hard blocks. Any ideas? I am just a few hours shy of reinstalling good old 10.04! Taake

• Why creating a new MDX language instead of extending SQL?

  - by DReispt

  I have a long experience with SQL, but recently began working with datawarehouse and OLAP technologies: building fact and dimension tables, that then are queried using MDX (MultiDimensional eXpressions). The problem is that MDX works with a completely different logic compared to SQL, and it's a whole new learning curve even for someone with a strong SQL background. Yes, MDX allows you to do things that would be hard or almost impossible with plain SQL. But sometimes it's frustrating to be hours around an MDX to do something you know you could achieve in minutes using SQL (ok, you can tell me to RTFM ...). But why go on to the trouble of creating a new completely different language when you could build on SQL, extend it to add the features needed by OLAP applications?
