• Windows 7 and 11.10 side by side from scratch what am I doing wrong?

  - by Bill.Caffery

  I have tried everything I can think of at this point and I'm at a total loss. I have a 2TB drive I want to install Windows 7 and 11.10 (both are 64 bit) side by side, but once I install Windows it must need gpt to work or something because no matter how many times I've removed it, it always returns. If I use gdisk and set the disk as mbr, Windows won't load. Now this last time I ran gdisk and tried to boot into Windows before I installed Ubuntu all the way and ended up at a grub rescue prompt. Any help please? Also let me say I have been searching and reading for days and have tried everything I can find to make this work so this isn't a one time event, it's continual.

• How to transfer a domain from 101domain to another registrar ?

  - by Wookai

  A friend of mine bought a domain name on 101domains, and now wants to have his website hosted on my servers. I would like to have full control of the DNS records, and thus would like to change the NS records to point to my DNS server. I can't find how to do that on their control panel. I can access the listing of DNS records for the domain, but cannot change it. Thus, I would like to transfer it to another registrar, that I know allows to do all these changes. How can I do that ?

• How can i get ubuntu to run smoother?

  - by Knuckles

  I am relatively new to ubuntu [I've used it before and loved it but one day i just randomly couldn't connect to the internet anymore so i switched back to windows... also netflix doesn't work in ubuntu...] and I've noticed that when i used it before everything ran very smoothly and the window animations and stuff like that were just beautiful. now though, everything is choppy and just ugly really. I wanna say its because i was using an older kernel but i really don't know. Anyway, i guess my point is, How can i get it to look pretty again? i really do wish i could be more descriptive but... yeah... I'm on Maverick btw. if anymore information is required i will happily oblige, just let me know.

• Wireless issues BCM4311

  - by user207757

  I have been working with a nice Gent but I am getting stuck. I am just getting back in to Linux and Ubuntu was recommended. I like the look so far but the wireless isn't working I run the update and when it says complete it hangs at the end. Please let me know what to do at this point. "wl: Running module version sanity check. - Original module - No original module exists within this kernel - Installation - Installing to /lib/modules/3.11.0-12-generic/updates/dkms/ depmod.... DKMS: install completed." Hangs here!! Thanks for all your help, D.C.

• How to tackle archived who-is personal data with opt-out?

  - by defaye

  As far as I understand it, it is possible to opt-out (in the UK at least) of having your address details displayed on who-is information of a domain for non-trading individuals. What I want to know is, after opt-out, how do individuals combat archived data? Is there any enforcement of this? How many who-is websites are there which archive data and what rights do we have to force them to remove that data without paying absurd fees? In the case of capitulating to these scoundrels, what point is it in paying for the removal of archived data if that data can presumably resurface on another who-is repository? In other words, what strategy is one supposed to take, besides being wiser after the fact?

• If I am developing a hosted payments page, what should the infrastructure look like?

  - by marcamillion

  If I am not storing credit card info, do I have to be concerned with PCI-compliance? I will be using a payment processor with a bank in my country. Literally just taking the credit card info and passing it to the gateway and processor. I would love to get an idea of the various technologies I might need to consider from an software architectural point of view. What are the best practices in terms of accepting credit cards and reducing fraud risk on my end? I will be creating the app in Rails.

• Determining if a visitor left your server

  - by Jeepstone

  We have an Apache server running a PHP website. The site is an e-commerce shop. We currently use Barclays as the payment provider but are seeing a lot of customers drop out at the point at which we transfer them to the payment gateway (hosted with Barclays) I can see specific instances in the shop where orders have been created but not paid/failed but I need to ascertain if the user has definitely left our server (or just failed to reach Barclays). Is there anything in any of the server/access logs that states when a user transferred to a different domain?

• I want to try and find and RFC for Business Listings.

  - by nc01

  I'm trying to figure out how to find out if there's a good standard format for sharing business information such as: Business Name Address - well-defined fields Lat,Lng Coords Business Type - maybe from a well-defined enum, my starting point contains Retail,Food,Drink,Coffee,Service Hours of operation - including a spot for 'except laksdasd' or 'sometimes we open late' which could be just plain language Business Keywords - don't know if this is asking too much. how well do http meta tags work in practice? So, if no such thing exists, is this something I can submit to IETF? I can't currently find it on http://www.rfc-editor.org/cgi-bin/rfcsearch.pl , and vCard doesn't suit my needs.. Thanks!

• How can one get involved in the Ubuntu Brainstorm team?

  - by Jay

  I've heard it thrown around on a lot of blogs that Ubuntu Brainstorm is the "graveyard of good ideas". I have a bit of a passion for average end-users suggesting the kinds of software they want and they way they think their applications and computers could work. I'm interested in joining the Ubuntu Brainstorm team, maybe to facilitate ideas not getting buried and making it not seem like a dead platform. Unfortunately I'm not very plugged into the "community" so I'm not sure how to go about it. I was hoping someone might be able to point me in the right direction. Thanks.

• XORG Issues- reported bug, what next

  - by user94927

  On Ubuntu 11.10 64 bit, after watching a video on VLC, I started getting screen freezes and unresponsive keyboard, and the mouse moves but clicking it doesn't do anything. I created a bug (1055240) and provided additional information but I'm not sure what happens next. I ran apport-collect 1055240 as suggested and somewhere during that process it told me to ask my question on Ask Ubuntu. So I'm wondering if y'all can tell me what I need to do? AFAIK I have provided the additional information that was requested. My PC is getting close to the point of becoming unusable- I just don't know which flash video is going to be the next one to cause it to lock up :-(

• Force apt-get to ask all install equations again?

  - by user204744

  I made a mistake. I answered the wrong way when installing something with apt-get. Now, when I purge it and reinstall it, it doesn't ask me the question any more. How do I force apt-get to ask me the question again? I'd really rather do this through the package manager than making the changes manually; that's the whole point of using a package manager.... The package in question is jackd. The first time I installed it, I answered "no" to the question about real-time priority. Now, I wish I'd said yes. However, even though I purge and install it again, I don't get the question. (I have tried dpkg-reconfigure jackd -- that doesn't give me any questions to answer.)

• Website creation preparation [closed]

  - by Loki

  I am in the pre-coding phase of creating a website. I know that it will be account based (users have to register/login to use the features). I also know that the server will have to do certain operations that are timer based, that is to say that user will have events that will trigger at a point chosen by the user and do something. I am searching for a good choice in server-side technology, and was wondering what my options are and what the best choice is. I would prefer open technology and something that doesn't use interpreted languages (Java, .net). My first thought is PHP + PGSQL for serverside and HTML+CSS+JS for clients, but I am still looking at my options.

• Distorted text in programs

  - by Teneff

  I've installed Ubuntu 11 with gnome and in some point the text in the programs becomes unreadable like this. It's not only the text, but even the desktop background looks awful. I've tried to add section in xorg.conf, but it didn't helped out. Section "Device" Identifier "g33/X3000" Driver "intel" BusID "PCI:0:2:0" Option "ModeDebug" "on" Option "MonitorLayout" "LCD,VGA" Option "DevicePresence" "true" EndSection And this is what the lshw returns about the VGA *-display description: VGA compatible controller product: 82945G/GZ Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 02 width: 32 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:16 memory:dfe00000-dfe7ffff ioport:8800(size=8) memory:e0000000-efffffff memory:dfe80000-d$

• How do I best remove an entity from my game loop when it is dead?

  - by Iain

  Ok so I have a big list of all my entities which I loop through and update. In AS3 I can store this as an Array (dynamic length, untyped), a Vector (typed) or a linked list (not native). At the moment I'm using Array but I plan to change to Vector or linked list if it is faster. Anyway, my question, when an Entity is destroyed, how should I remove it from the list? I could null its position, splice it out or just set a flag on it to say "skip over me, I'm dead." I'm pooling my entities, so an Entity that is dead is quite likely to be alive again at some point. For each type of collection what is my best strategy, and which combination of collection type and removal method will work best?

• Calculate initial velocity of a 3d vector-based projectile

  - by Frotty

  Okay, so I got a Projectile with 2 Vectors, position and velocity. I now want to calculate the initial velocity for it in order to reach a specific point on the map. Or actually, how high has the start z-velocity to be (because x and y are probably defined by a speed variable) in order for the projectile to hit the marked position. The projectile is influenced by a constant gravity vector. All calculations are done 32 times per second. I want this, because I don't want to use a parabola function, so the projectile can still be influenced by other sources, simply adding some velocity. I didn't really find anything referring to that topic and would be glad for every helping answer, Thanks.

• Package version updates policy

  - by Sandman4

  Not sure if here it's the right place to ask, if not - please point me to the right direction. Let's say there's a package, for the sake of real-world example - bind9. In Precise and in Quantal it's version 9.8.1. The original developer (ISC) currently provide versions 9.8.4 which is a bugfix release in the 9.8 line, and 9.9.2 which is a "new features" branch. It looks like when a security issue is encountered, the specific bugfix is backported into 9.8.1. Now the question: Why maintainers don't just update to the latest bugfix release ? Why to backport only certain patches ? Is it intentionally or just there's no maintaner who would take the effort to update to the latest bugfix release ?

• Mouse click firing twice

  - by Luke

  I have recently switched to XUbuntu (14.04) and I have noticed that sometimes a mouse click is fired twice. E.g. I CTRL click a link and two tabs with the same content are opened in my browser. It's not behaviour I can reproduce consistently and seems to be random (to me). I also don't know of a good way to inspect the behaviour properly for debugging purposes. I have checked the double click time setting but this doesn't seem to have any impact on this. I also run XUbuntu (13.10) in a VM on my MacBook Air and this behaviour seems to absent there. At this point in time I can't really tell if this is related to the distribution or the fact that it runs in a VM. Any insights greatly appreciated.

• Why did 13.10 break my custom keyboard layout?

  - by con-f-use

  I was using a custom keyboard layout. Basically I modified the us-mac layout to fit my ideal of a math-heavy version of the regular us layout that also throws German umlauts into mix. It went well and worked marvelously for 6 consecutive versions of Ubuntu. Today's version Upgrade (from 13.04 to 13.10) broke that streak. I now have the usual crappy Macintosh-Layout. Now xkb just ignores my layout and all of the other changes I make in /usr/share/X11/xkb/symbols/us (tried to switch '0' and '9' everywhere and rebooted - no effect). Why is that? I suspect I have to do an extra step now for the changes to take effect or something like that. Anyone care to point me in the right direction?

• Expression Engine vs Drupal for Theming

  - by user793011

  Ive been using Drupal for years and now with work need to learn Expression Engine. Im interested in the comparison of Drupal and Expression Engine, but purely from a theming point of view (Ive no doubt Drupal is more powerful for development). Does anyone have any insights? It seems EE does give you more control over the exact html outputted, but is this necessary? I design my graphics first and Ive always been able to make exactly what I wanted in Drupal (some theme overrides could be easier, but ive got there in the end). Thanks

Improbable ou impossible à reproduire, racontez-nous votre meilleure histoire de débogage Si le débogage est l'art d'enlever les bogues, la programmation doit être l'art de les créer. Une expression chère à beaucoup de développeurs qui souligne à quel point le débogage d'une application peut être important et... problématique.

• rotate opengl mesh relative to camera

  - by shuall

  I have a cube in opengl. It's position is determined by multiplying it's specific model matrix, the view matrix, and the projection matrix and then passing that to the shader as per this tutorial (http://www.opengl-tutorial.org/beginners-tutorials/tutorial-3-matrices/). I want to rotate it relative to the camera. The only way I can think of getting the correct axis is by multiplying the inverse of the model matrix (because that's where all the previous rotations and tranforms are stored) times the view matrix times the axis of rotation (x or y). I feel like there's got to be a better way to do this like use something other than model, view and projection matrices, or maybe I'm doing something wrong. That's what all the tutorials I've seen use. PS I'm also trying to keep with opengl 4 core stuff. edit: If quaternions would fix my problems, could someone point me to a good tutorial/example for switching from 4x4 matrices to quaternions. I'm a little daunted by the task.

• Circular movement - eliminating speed ups near Y = 0

  - by Fibericon

  I have a basic algorithm to rotate an enemy around a 200 unit radius circle with center 0. This is how I'm achieving that: if (position.Y <= 0 && position.X > -200) { position.X -= 2; position.Y = 0 - (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } else { position.X += 2; position.Y = (float)Math.Sqrt((200 * 200) - (position.X * position.X)); } It does work, and I've ensured that at no point does either X or Y equal NaN. However, when Y approaches 0, it seems to go significantly faster. This surprises me, because the Y values are locked to the X, which is being incremented by a steady amount. What can I do to smooth the speed?

• Is there any complications or side effects for changing final field access/visibility modifier from private to protected?

  - by Software Engeneering Learner

  I have a private final field in one class and then I want to address that field in a subclass. I want to change field access/visibility modifier from private to protected, so I don't have to call getField() method from subclass and I can instead address that field directly (which is more clear and cohessive). Will there be any side effects or complications if I change private to protected for a final field? UPDATE: from logical point of view, it's obvious that descendant should be able to directly access all predecessor fields, right? But there are certain constraints that are imposed on private final fields by JVM, like 100% initialization guarantee after construction phase(useful for concurrency) and so on. So I would like to know, by changing from private to protected, won't that or any other constraints be compromised?
