• Programming language for simple program?

  - by jamherst

  I am wondering about which programming languages people see fit to create a program idea that I had. I am looking to create a fairly simple program whose main functions are adding to, managing, and searching through a database of people, all through a polished GUI. It will be for use in the business world, so I think Windows would be the priority, but Mac and Linux support wouldn't be bad. Also, eventually I would like to add the ability for an instance of one program on a computer to interact with other instances on the same network, mainly through the sharing of a database. Most of my experience is in Java, but I don't particularly like the appearance of Java GUIs, so I'm looking for an alternative. I noticed that a lot of people have suggested C++ or C# in similar posts, so what are some of the advantages/disadvantages of one or both if that is your suggestion. Thanks for any help in advance.

• Windows 8 on my new i7 Macbook Pro

  - by Bob Hardister

  Using bootcamp I installed Windows 8 on my new Macbook Pro 15" (not a retina screen version), which has OS X 10.8.2, 2.6 Ghz Core i7 with 8 GB RAM.  I followed the simple procedure outlined here. The only problem I had was the wireless device driver wasn't provided. I had to find and download it myself. Even so it only provided 5G not 2G protocol support. I downloaded a Broadcom driver.   I was able to enable the Hyper-V features on Windows 8 and look forward to using VMs. So far so good :)

• Ubuntu 11.0 HDMI Video Card No 5.1 Audio

  - by ryandlf

  I am using Ubuntu and XMBC on my HTPC and have chosen the Radeon HD5570 Video card which has an HDMI output. In the sound preferences there is no surround sound option for the video card just stereo and although I can get sound through it in XBMC, my receiver does not state Dolby Digital on movies that are in fact Dolby so its definitely not giving me the true sound it should. Does this card not support surround sound through HDMI and I somehow missed it? If that is the case does anyone have suggestion that has been tested and works? Id like to know its going to work before investing in yet another video card.

  Kernel Linux : la version stable 2.6.38 est disponible Elle optimise la fonction de résolution de la couche VSF La version stable 2.6.38 du noyau Linux vient d'être rendue disponible et annoncée officiellement par Linus Torvalds.

• How to recover Wordpress on GoDaddy hosting after reseting database password? [migrated]

  - by Tom Brito

  I did reset my database password, so I could enter the phpMyAdmin, but now my Wordpress installation can't connect to the database. I tried to access the "wp-config.php" (should be at http://mysite.com/wp-config.php right?) but, again, I get the "can't connect to database" message. Also, now when I try to access the file manager on the GoDaddy hosting, I get "The page isn't redirecting properly". I did e-mail the GoDaddy support, and I'm researching while they do not answer. Not sure if it's a GoDaddy or Wordpress issue. Is there any way to fix Wordpress, or I'll need to re-install it?

• Sending Mass Emails

  - by Larry Anderson

  I have a massive list of users who registered for accounts and opted into a mailing list on my web site and I am interested in sending out a weekly newsletter. How should I go about doing this. I tried sending it out through my host server, but I received a notice stating that if I did it again they would kick me off the server. Are there any good companies that are designed for this type of thing? I need to find a company that will support this and show me some sort of report about how many emails get opened, deleted, opened then deleted, etc. Any recommendations?

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• How can I implement full disk encryption for a disk containing Ubuntu with plausible deniability?

  - by Rupert

  I would like to have a disk that: has Ubuntu installed is fully encrypted is setup in such a way as to make denial of the existence of the Ubuntu install plausible Truecrypt provides the last two features but only for Windows: http://www.truecrypt.org/docs/?s=sys-encryption-supported-os The alternate installer for Ubuntu provides the first two features but not the last. I imagine that plausible deniability would be achieved by, at least: Having two installs of Ubuntu and 2 passphrases (or keyfiles) which would unencrypt each one. Moving any unencrypted data (such as /boot) onto a USB stick Are there any programs out there which support this feature set for Ubuntu?

• Should I switch my graphics mode in the BIOS to avoid using Bumblebee?

  - by Fawkes5

  I have just purchased a Acer 3830TG, the timeline X series. To my surprise I found out that there is no first-party support for nvidia optimus for linux. Bumblebee works great, but the battery life from the graphics card always running is not so great. I don't use linux for games so i don't really need the graphics card on, I have Windows for that. In my bios, I have the ability to change my graphics mode from switchable to integrated. If I do this, reinstall ubuntu, what will happen? Will my nvidia card just turn off? Will everything work properly, as if i'm not running an optimus laptop? Is this recommended as opposed to dealing with bumblebee? What is the best thing I could do?

• Can GJK be used with the same "direction finding method" every time?

  - by the_Seppi

  In my deliberations on GJK (after watching http://mollyrocket.com/849) I came up with the idea that it ins not neccessary to use different methods for getting the new direction in the doSimplex function. E.g. if the point A is closest to the origin, the video author uses the negative position vector AO as the direction in which the next point is searched. If an edge (with A as an endpoint) is closest, he creates a normal vector to this edge, lying in the plane the edge and AO form. If a face is the feature closest to the origin, he uses even another method (which I can't recite from memory right now) However, while thinking about the implementation of GJK in my current came, I noticed that the negative direction vector of the newest simplex point would always make a good direction vector. Of course, the next vertex found by the support function could form a simplex that less likely encases the origin, but I assume it would still work. Since I'm currently experiencing problems with my (yet unfinished) implementation, I wanted to ask whether this method of forming the direction vector is usable or not.

Everything works flawlessly. It was a seemless setup.

• Implementing RAID 1 in Ubuntu 10.04 Desktop [closed]

  - by Dibyendra

  I found many resources on implementing RAID 1 using two disk drives. But, I am confused while implementing RAID 1 using 4 RAID disks. Can we use two disks for storage and two for mirroring using RAID 1? I couldn't find the way to create RAID disk using gparted tool in Ubuntu 10.04 Desktop version. Maybe, the desktop version doesn't support RAID. I am trying to implement RAID on the existing Ubuntu installation? I have added 4 X 2TB HDD in the system and I want RAID 1 to be implemented in these 4 drives with 2 drives for storage and 2 devices for mirroring. Any help would be appreciated. Thanks! Updated: I installed Ubuntu 12.04 LTS and followed the following tutorial and it works now: www.youtube.com/watch?v=z84oBqOxsD0

• Slow Wireless Reconnect After Suspend

  - by nrhine1

  I a Broadcom 4312 using the STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues. My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.) I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/ which basically says to change this: STOP_SERVICES="" to STOP_SERVICES="networking" in the file /etc/default/acpi-support This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

• What is the Ubuntu equivalent of the Windows programs Belarc or PC Wizard?

  - by CeltaWeb

  I provide technical support for several high schools in Spain and I have been building up a inventory of the schools machines. On the windows only computers I normally run PC Wizard to quickly get a good overview of the machines hardware, software and network settings. Is there an equivalent tool preferable with a GUI and an export option to html or pdf in Ubuntu. I have tried a few options such as: Gnomes gconf-editor hardinfo (GUI) lshw (CLI) I'm just looking for an all in one application that builds a detailed profile of the installed software, hardware and network setting of a particular machine. I have found Sysinfo which is quite good, it displays the most important hardware info and allows you to save it to a text file with a neat GUI. I'm still looking for a more complete solution but it's a good start.

• Flash Retirement - HTML to be "the one"

  - by RichMill

  I will update this blog post as we get closer to the retirement of the Flash portal. As you might have read the support.oracle.com  flash site will be replaced with what you see in supporthtml.oracle.com,  once we get the rest of the features and functions ported over to the html site. The HTML site is written using Oracle's ADF stack. So we are now pretty much 100% eating our own dog food.  More details to follow.
