• 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)

• VMWare Unity Mode with Ubunty 12.10

  - by Nick

  This is a very difficult thing to search for, and find an answer to because of the unfortunate choice VMWare and Ubuntu both having something called "Unity". My host operating system is Windows 7 - 64 bit, running VMWare Workstation 9.0.1. I have a virtual machine running Ubuntu 12.10 - 64 bit. When I attempt to put VMWare in "Unity mode", I get the following message: The virtual machine cannot enter Unity mode because: - Unity is not supported on the guest operating system. From the VMWare site, there is nothing listed that says that Ubuntu is not supported for this... and I have installed the latest vmware-tools on the guest operating system. It seems like a lot of people have had this issue, but I haven't seen a good resolution to it yet. Does anyone know how to get Unity mode working with Ubuntu?

• How do I find out on which partition is my Windows?

  - by Perlnika

  I have fully functional Windows and Ubuntu that is broken (I accidentaly broke it) and want to do reinstall. With Live-CD, I can see: 3 NTFS partitions, one ext4 and one unknown. How do I find out which partitions belong to Windows? I thought that I might delete everything that wasn't NTFS, but I was afraid. Now I am using: Install Ubuntu alongside them option, but I guess that this will leave my broken Ubuntu untouched. So, again, I need to know which partitions to merge (perhaps add partitions of broken Ubuntu to new Ubuntu?). Please, how can I learn how my system is divided? Thanks a lot.

  - by Matheus

  I'm having a trouble when trying to install Skype on my Ubuntu 12.04.1 x64. My notebook have compatible hardware with Ubuntu. My previous OS installed on this machine was the Ubuntu 12.04 x64 and Skype was working great, but I got a formatation and I installed the New ubuntu 12.04.1.

Something like i have the skype-bin package missing (or broken). I can't find it on Software center. I tried to install it by downloading a deb package with the skype-bin package but it ask for a lot another packages! I tried install the .deb package from the official Skype site, but I got the same error! Any Help? Sorry about my bad English, I'm Brazilian

• Split large file, have arbitrary start index number

  - by nEJC

  I do a lot of file manipulation on my system and in one particular batch job I end up with around 16 Gb file. I need to prepare this data into smaller chunks for another process. I split it into 10k lines per file and numeric index, padded to 5 digits split -a 5 -d -l 10000 large_input_file /out_path/out. This way I end up with files named out.00000 out.00001 ... The problem is that this way indexing always starts with 0. Is there a way to set it to arbitrary starting index? man reveals nothing ...

• What effect does using itemprop="significantLinks" on anchors have for SEO and what is the ideal use?

  - by hdavis84

  I'm practicing application of microdata via http://schema.org. Anyone who's browsed the documentation there knows that there's a lot of need for improvement for more clear understandings on use for each property. My question on this post is more about the "significantLinks" property and how it effects SEO for on page, in content anchored text. Does anyone have any more information regarding whether its good to use for link optimization? I understand what schema.org means that it's to be used on "non-navigational links" and those links should be relevant to the current page's meaning. But will using this property hurt SEO or make SEO better for each page?

• Where can I get a list or data base of light reflectance values for different materials?

  - by mikidelux

  I'm implementing lighting for a WebGL app but I'm not an artist so I don't know how to generate or where to obtain a list of materials with its values (diffuse, specular, ambient and shininess). I've been searching a lot but with no luck. Is there any list or DB I might have overlooked? Any common repository or something similar? Thanks in advance. Note: English is not my main language, let me know if you don't understand something and I'll try to rephrase it.

• Progressing past CRUD applications in PHP?

  - by Anonymous -

  I've been programming in PHP for about a year and am at the following stage: Have a good 'feel' for the language Can create CRUD applications competently Can utilize an MVC structure to allow for future expansion of code Using the points listed above, I've created a number of my own applications for practise - including but not limited to; a forum, social network etc. My question may be a little vague but should hopefully be answerable. I feel as though there isn't anything else I would need to know about PHP to allow me to create websites, though I'm sure I'm wrong. What advanced/complex PHP topics could I look at that have a real-world use and will allow me to enhance both my skill as a programmer and applications in general? Recently I've looked a lot more at javascript/jQuery allowing me to give my applications a richer user interface which has been a great learning experience and proving very useful.

• Are people getting away with the "follow 1000s and then unfollow" Twitter trick? [closed]

  - by Baumr

  It seems that more and more people are trying to 'cheat' their way into more Twitter followers. The basic mechanism is: Follow thousands of people on Twitter with the hope that they'll follow you back. Once it reaches a point you're happy with, start gradually unfollowing them. That way, at the end of the day, it'll look like a lot of people follow you unconditionally. I've seen self-proclaimed social media and SEO experts do this. It's clear they want to look influential — and will use black hat social media tactics to do so. I can see how it can work, so is Twitter letting them get away with it? Should it?

• My Inbox: How to save changes coming from disconnected POCOs

  I receive a lot of random emails from developers with Entity Framework questions. (This is not a request for more! :)) If I’m too busy to even look or if it’s something I can’t answer off the top of my head, I swallow my pride and ask the person to try the MSDN forums. If the email is from a complete stranger and has gobs and gobs of code that email will surely get a "please try MSDN forums" reply.  But sometimes I’m not in my usual state of “too...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Is there an opposite for the term "Backporting"?

  - by Avian00

  As I understand, the term "Backporting" is used to describe a fix which is applied in a future version which is also ported to a previous version. Wikipedia definition is as follows: Backporting is the action of taking a certain software modification (patch) and applying it to an older version of the software than it was initially created for. It forms part of the maintenance step in a software development process... For example: A problem is discovered and fixed in V2.0. The same fix is ported and applied to V1.5. What is the term when this is done in the opposite direction? The problem is discovered and fixed in V1.5. The same fix is ported and applied to V2.0. Would the term "Backporting" still apply? Or is there a term such as "Forwardporting" (which amusingly sounds a lot like "Port Forwarding")?

• Ubuntu 12.04 intermittently fails to wake up from sleep

  - by stacksia

  When I put my Ubuntu 12.04 machine into sleep, sometimes on waking up, it fails, logs me out, and takes me back to login screen. When I log back in, it tells me some unexpected error happened, but it fails to let me report the bug. This has started to happen recently, but I don't know what triggered it. uname -a Linux [name] 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux The issue seems similar to Xorg intermittently restarts after suspend. But in my case I am not sure if it is a Xorg issue. I looked at xorg logs, but didn't notice anything indicating an error. I know I am not providing a lot of info, but I am not sure where (e.g. which log files) I should seek for more info.

• Will the world depend less of developers?

  - by nmiranda

  Hi everybody, yesterday I had a little chat with a friend that is in the field of development as I am. And he told me that he planned to change of business, I mean, he wants to get off developing cause he doesn't think that it has future. "There will come days were you could have a job as a developer but you would never get rich" he said. "Nowadays is more important to have an idea and develop it in a product than being a software developer. Today you can find a lot of applications that can help you to make it. We have already non-sql databases, better cases than 10 years ago and other tools much of them free, everything is directed to depend less of developers and you'll see it more 10 years from now" Do you agree with that?

• Adding users to multiple/all sites in Google Webmaster Tools?

  - by Christian

  I didn't find an answer to this, but maybe I didn't use the right terms for my search. So I'm sorry if this is a duplicate. Anyway, my situation is this: the company I work at manages a lot of sites (100+), and we've recently put them all into Google Webmaster Tools under my Google account, which was tedious enough. Now two coworkers are supposed to be added as users for each site, so they can see the data and manage stuff there as well. But I can only find an option to add users for a single site, not for all sites that are currently associated with my account. Do I really have to go through more than a hundred sites one by one and add the two users to each of them, or is there some way to add both users to all/multiple sites at once?

• Ubuntu 12.04 appearance

  - by lightnight

  I have just updated my old Ubuntu 11.04 to the 12.04 version and I really dislike the new appearance. Is there anyway I can go back to the old appearance? Here are some examples of the things I would like to change: the omnipresent orange colour (for example, colour of the folders, colour of the little x on the top right of the window etc.); used to be blue. The icons on the right vertical bar are unreadable: the dropbox icon has become a light grey shapeless blob, the battery icon does not indicate, as it did before, when electricity is plugged in and when it isn't. everything is just grey and orange (I chose the Radiance theme, the other ones are even worse). There used to be a lot of options choosing the shape of the windows and so on, where has all that gone? Thanks for your help!

• Fresh start outside Google's crapbox [on hold]

  - by Krzysztof Minister Bytu

  I might have been experimenting with my website too much and Google first cut the flow of visitors considerably and now I didn't get one for 4 days already. It's a joke that they've done this, because I've put a lot of work into it, but that's a topic for another day. My question is about further avoiding it. I want to take the partly improved design from that website onto a new one and get a new domain name. The question is: in that case, do I have to change the hosting option (it has my old website name in the address), or is changing the domain enough for Google to treat it as something new from a "fresh user". In other words, does Google get through the domain address and log into the actual hosting address? I'd hate to waste another few months of hard work, so I prefer to take every possible precaution but not paying for another hosting would make things easier on the wallet.

• Ubuntu 12.04 cannot start

  - by user57215

  I just installed Ubuntu 12.04 64bit, and I cannot start it. I tried twice. The first time, I used a CD I burned. (The CD works for my another computer, so it is OK.) After wubi did something in Windows, it rebooted. Then the screen was stuck where there is an ubuntu logo at the center and 5 dots below. I waited for more than half hour, it was still there and nothing happened. The second time, I installed 11.10, then upgrade to 12.04 in a the newly install 11.10. BTW, the 11.10 did start. After upgrading, I rebooted the computer, it was stuck at the same place. Any one can help me on this? The computer is AMD Phenom II X4 965 + ATI RADEON HD4870. Thanks a lot!

• Bluetooth automatic mouse connection not working

  - by Ray B.

  I'd like my HP Bluetooth Mouse x4000b (no usb dongle) to connect automatically when starting my HP laptop (Ubuntu 14.04), but I can't succeed in it : I'm forced to do it manually by clicking the "connect" button. I know this topic has been answered many times, but no solution worked for me. Here's what I tried so far : Creating the file /etc/default/bluetooth with lines : HIDD_ENABLED=1 HIDD_OPTIONS="--connect F0:65:DD:7D:EC:A0 --server" Putting hciconfig hci0 reset at the end of /etc/init.d/bluetooth Putting /etc/init.d/bluetooth stop sleep 1 /etc/init.d/bluetooth start in /etc/rc.local None of these solution worked, I've read a lot of topics but couldn't find a solution ... that's why I'm asking that here, hoping you can help me troubleshooting that. Thank you ! Ray

• Online Syntax Colorizer

  - by lavanyadeepak

  Online Syntax Colorizer For those of us who share code snippets along with articles the most daunting problem would be to preserve the syntax colorizations. There are a few ways to manage through this additional requirements: Tweak and point the color picker in the article textearea. Import the code to a word processor and then copy the code. However, the word processor would unnecessarily swell the contents with too much of formatting contents. Quick Online Colorizer: http://tohtml.com/ (This supports a lot of languages including autodetection). I would also recommend if GWB could link to this website and auto-colorize the code when we paste it in our articles.

• What does well written, readable tests look like?

  - by Industrial

  Doing unit testing for the first time at a large scale, I find myself writing a lot of repetitive unit tests for my business logic. Sure, to create complete test suites I need to test all possibilities but readability feels compromised doing what I do - as shown in the psuedocode below. How would a well written, readable test suit look like? describe "UserEntity" -> it "valid name validates" ... it "invalid name doesnt validate" ... it "valid list of followers validate" ..

• Install software with 12.04

  - by tigris

  Just freshly installed from 12.04 after using 11.04 and dist-upgrading to 11.10 a few months back, figured a fresh installation was due. First thing I noticed is that synaptic is no longer installed by default. I've no issues with this, and assume the approach to install packages is now via the ubuntu software center. However, I notice there are a lot of packages missing. I was looking for "vagrant", which I've had to install manually with a sudo apt-get install, but was hoping to use GUI for most things. Surely there is a GUI way? I also noticed when checking for "vim", it comes up with gVim and a little note at the bottom saying "show 2 technical items", which when clicked shows the vim I was looking for. Just curious what the expected GUI way is of installing these supposed "technical packages".
