How to create a bootable Ubuntu Linux (10.04) USB installation for Macintosh

- by vdavidovski

I tried searching the Internet, but could not find a decent tutorial explaining how to create a bootable Ubuntu Linux (10.04) USB installation that could be run not only on a PC but also on Macs and MacBook Pros. In addition, I tried refit, but ended with "Missing operating system" error. Here is basically the layout of my bootable under PC Ubuntu USB drive (using MBR): Partition 1 (ext3, bootable) - Ubuntu Linux 32 bit, contains also grub2 bootloader. Partition 2 (ext3) - Ubuntu Linux 64 bit. Partition 3 (fat32) - contains data. What would be the best way to enable this drive to boot under Mac OS X? And if refit has to be used, could I simply have one more partition on the USB drive containing it? Thanks!

How to hide the mouse cursor

- by MvG

I'm building a kiosk using Ubuntu Precise on a touch screen. Now I'm looking for the appropriate way to make the mouse cursor disappear. As people know where they are pointing, displaying an arrow under their finger is useless, and having an error where they last pointed even more so. My best bet would be some kind of cursor theme consisting only of transparent cursors. I'm a bit surprised to find no UI to switch and maybe install cursor themes the default Unity UI, but as I won't be using Unity, that's not much of a problem. It appears that the alternatives listed in update-alternatives --list x-cursor-theme all refer to .theme files, so I searched the package list for those. The resulting list does not list any likely candidates, i.e. no packages containing “invisible” or “transparent” in their name. So far, some googled result yielding a readme for “XCursor Transparent Theme” is my best bet. That would mean compiling those sources myself, perhaps putting them into my PPA. I'm also a bit sceptical about that result as said readme is dated from 2003. And I'm not sure that I'm not making things overly complicated. After all, there is quite some support in Precise for touch devices, so I don't believe I'm the first one who wants to get rid of his mouse cursor. Is there another way which doesn't involve user-compiled binary code? Is there a theme package for transparent cursors which I've overlooked? Is there some other mechanism to make the cursor disappear without changing the cursor theme? I'll be using Matchbox WM, Firefox and Java applets, so I'll be happy with any solution working under such a setup. I'm not interested in any solutions twiddling with Gnome or Compiz, as I'll not be running either.

Intel 5100 AGN disconnects and then disables my Verizon FiOS Actiontec router

- by Anthony

I am a new user (my first trial) of Ubuntu and booted up my Windows Vista laptop up with the Ubuntu CD. I was able to connect wirelessly to my router and stay connected for about a minute. After that it would disconnect and my router would be disabled: none of my other wireless devices would see the signal any longer, as if it disappeared. I would have to cycle the router's power toggle off/on to get it to come back on and put out a signal again. This happened repeatedly. I experienced no other problems trying the software (i.e., accessed my files w/o issue). I did not attempt to connect with an Ethernet cable. Here are the specs on my system: laptop is HP Pavilion dv5 Notebook PC system type is 64-bit operating system CPU is Intel Core 2 Duo P8600 2.4GHz ram is 4 GB network card is Intel WiFi Link 5100 AGN I read elsewhere in this forum that 64-bit systems may not be compatible with Ubuntu. Can anyone help me with this? I'd really like to be able to use this op system.

Building a linux system

- by webyankee

I am worried about hardware compatibility. I have several older PCs with various hardware and wish to install Linux onto them. I have several ideas about what I would like to do. first, I am a novice and know just enough to get me into trouble in a lot of areas. I can not find adequate descriptions of the usage between a desktop and a server version of Linux. When would you want to choose to build a server instead of a desktop and can you change a desktop to a server if you need higher functionality? I wonder if I should use 32 or 64 bit? I believe 32 bit on older (P1 or P2 systems) would be the safe way to go. what is the extent can these systems be used? Can they used to play high end graphics on-line games or just simple browsing and word processing? How do I determine what programs the system can use? I have pondered on the idea of linking several systems together to make one big computer. I know this can be done with some functionality improvement. Any Ideas about this?

Why create a Huffman tree per character instead of a Node?

- by Omega

For a school assignment we're supposed to make a Java implementation of a compressor/decompresser using Huffman's algorithm. I've been reading a bit about it, specially this C++ tutorial: http://www.cprogramming.com/tutorial/computersciencetheory/huffman.html In my program, I've been thinking about having Nodes that have the following properties: Total Frequency Character (if a leaf) Right child (if any) Left child (if any) Parent (if any) So when building the Huffman tree, it is just a matter of linking a node to others, etc. However, I'm a bit confused with the following quote (emphasis mine): First, every letter starts off as part of its own tree and the trees are ordered by the frequency of the letters in the original string. Then the two least-frequently used letters are combined into a single tree, and the frequency of that tree is set to be the combined frequency of the two trees that it links together. My question: why should I create a tree per letter, instead of just a node per letter and then do the linking later? I have not begun coding, I'm just studying the algorithm first, so I guess I'm missing an important detail. What is it?

What's the proper term for a function inverse to a constructor? Deconstructor, destructor, or something else?

- by Petr Pudlák

Edit: I'm rephrasing the question a bit. Apparently I caused some confusion because I didn't realize that the term destructor is used in OOP for something quite different - it's a function invoked when an object is being destroyed. In functional programming we (try to) avoid mutable state so there is no such equivalent to it. (I added the proper tag to the question.) Instead, I've seen that the record field for unwrapping a value (especially for single-valued data types such as newtypes) is sometimes called destructor or perhaps deconstructor. For example, let's have (in Haskell): newtype Wrap = Wrap { unwrap :: Int } Here Wrap is the constructor and unwrap is what? I've seen both, for example: ... Most often, one supplies smart constructors and destructors for these to ease working with them. ... at Haskell wiki, or ... The general theme here is to fuse constructor - deconstructor pairs like ... at Haskell wikibook (here it's probably meant in a bit more general sense). The questions are: How do we call unwrap in functional programming? Deconstructor? Destructor? Or by some other term? And to clarify, is this terminology applicable to other functional languages, or is it used just in the Has

Internet Explorer 9 is coming Monday to a web near you

- by brian_ritchie

Internet Explorer 9 is finally here...well almost. Microsoft is releasing their new browser on March 14, 2011. IE9 has a number of improvements, including: Faster, Faster, Faster. Did I mention it is faster? With the new browsers coming out from Mozilla, Google, and Microsoft, there have been a flood of speed test coverage. Chrome has long held the javascript speed crown. But according to Steven J. Vaughan-Nichols over at ZDNET..."for the moment at least IE9 is actually the fastest browser I’ve tested to date." He came to this revelation after figuring out that the 32-bit version of IE9 has the new Chakra JIT (the 64-bit version doesn't). It also has a DirectX-based rendering engine so it can do cool tricks once reserved for desktop applications. Windows 7 Desktop Integration. Read my post for more details. Unfortantely, they didn't integrate my ideas...at least not yet :) Hot new UI. Ok, they "borrowed" some ideas from Chrome...but that is the best form of flattery. Standards Compliance. A real focus on HTML5 and CSS3. Definite goodness for developers. So, go get yourself some IE9 on Monday and enjoy!

Fix: Cant Change or Remove Visual Studio 2008 from DVD

If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image). I believe this is because of the path used to install the 32-bit Visual Studio program. When you run the setup.exe off of the disk, you get this: Clicking on Change or Remove Visual Studio 2008 brings up this dialog: But not long after it appears, it disappears to be replaced with: Microsoft Visual Studio 2008 Setup A problem has been encountered while loading the setup components. Canceling setup. FIX: Use Add or Remove Programs Launch the Add or Remove Programs dialog in Windows, and find Microsoft Visual Studio Team System 2008 Team Suite ENU (or whichever SKU you installed). Click Uninstall/Change. From here you should be able to change your installed components of Visual Studio successfully: Thanks to Brendan for the tip! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

How to see whats taking up space on your hard drive

- by sam

Im thinking of switching to one of the macbook pro retinas with a 256gb ssd, im making the move from a 512gb hd, which at the moment is split into a 60bg windows partition (which i dont think im going to have on my new machine) and a 440gb main partition of the main partition ive got 140gb free. So all in if i disregard the 60gb windows part ive got about 200gb free so im using 300gb, which is still a bit to much, ive had this machine 4/5 yrs so its likely to be clogged with files that i no longer need, is there a tool that i can use to view my current hd and see whats taking up the most room, so i can begin to see where i can cut down ? just for a bit of background my current machine runs osx.

First Project a big one, How much should we charge?

- by confuzzled

Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

Alternatives for HP ProtectTools on EliteBook 2530p

- by AlexDuggleby

Hi, I'd like to use the HP fingerprint sensor on my Elitebook 2530p. The system is a fresh Win7 Enterprise 64-bit and we are looking for an alternative to the HP ProtectTools Security Suite, which seems a bit bloated. We have tried the UPEK ProtectorSuite (both WBF and stand-alone edition) and they say they can't find the fingerprint device. The device shows up in device manager, in the BioMetric system configuration I have enabled logon to Windows and Domain credentials. Are there any other fingerprint login software (free or commercial) that you can recommend. Thanks in advance, Alex

Vector vs Scalar velocity?

- by Serguei Fedorov

I am revamping an engine I have been working on and off on for the last few weeks to use a directional vector to dictate direction; this way I can dictate the displacement based on a direction. However, the issue I am trying to overcome is the following problem; the speed towards X and speed towards Y are unrelated to one another. If gravity pulls the object down by an increasing velocity my velocity towards the X should not change. This is very easy to implement if my speed is broken into a Vector datatype, Vector.X dictates one direction Vector.Y dictates the other (assuming we are not concerned about the Z axis). However, this defeats the purpose of the directional vector because: SpeedX = 10 SpeedY = 15 [1, 1] normalized = ~[0.7, 0.7] [0.7, 0.7] * [10, 15] = [7, 10.5] As you can see my direction is now "scaled" to my speed which is no longer the direction that I want to be moving in. I am very new to vector math and this is a learning project for me. I looked around a little bit on the internet but I still want to figure out things on my own (not just look at an example and copy off it). Is there way around this? Using a directional vector is extremely useful but I am a little bit stumped at this problem. I am sorry if my mathematical understanding maybe completely wrong.

Why is my fresh install of 12.04 running slow?

- by user75129

Hey guys I'm a new linux user, I figured it would be the best for the laptop I just purchased because it's said to be faster than Windows 7. I'm currently dual-booting with Windows 7 Professial and Ubuntu 12.04. The laptop I am using is the LG X Note P210 Specs: Intel Core i5 470UM Dual Core clocked at 1.33GHz 12.5" HD LED LCD Screen at 1366 by 768 4GB DDR3 @ 1333 MHz RAM Integrated Intel HD Graphics Card 4 Cell Battery with 3150mAh It comes loaded Windows 7 Home Premium 64-Bit, it runs fine on that but my Ubuntu 12.04 runs slower than it and I don't understand why, it definitely has decent specs to run even a 64-bit operating system and do some gaming. Granted I know it's not the best but for a laptop it does the job so Ubuntu should work especially since it's said to make older units with worse specs run even better. I'm not all that familiar with coding and all so what are things I can do to optimize speed without overclocking? Boot up is fine, its program response time I believe, once Im in the actual OS, it lags, slows down, apps stop working, take forever to load up apps.

Screen goes grey in Remote Desktop Connection from windows 7 to ubuntu server

I recently got a 64 bit ubuntu server based on Ubuntu Desktop 12.04 "Precise Pangolin". However I can't seem to connect to it properly from my windows 7 64 bit machine. I can get to the login screen for ubuntu, and it seems to succeed in logging in, but then the screen just goes grey before anything comes up. (too low rep to post a picture) I installed xrdp on the server and attempt to connect using the standard windows Remote Desktop Connection program. I also ran the following 2 commands on the ubuntu machine to try get it to run but it was no help. echo "gnome-session --session=ubuntu-2d" > ~/.xsession and sudo apt-get install gnome-session-fallback

Setting up Kerberos SSO in Windows 2008 network

- by Arturs Licis

We recently introduced Kerberos (SPNEGO) Single Sign-on in our web-portal, and tested it on a Windows network with Windows 2003 domain controller. Now, trying to test it on Windows 2008 R2 controlled network, SSO just doesn't work due to defective tokens. Up to the moment I was pretty sure that there's something wrong about environment and that were NTLM tokens. We double checked IE settings etc, but nothing helped. Then we checked the following settings for both users (logged on a client test-machine, and the one used as a Service Principal): This account supports Kerberos AES 128 bit encryption. This account supports Kerberos AES 256 bit encryption. .. and error message changed to ' GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256CTS mode with HMAC SHA1-96 is not supported/enabled) It makes me think that Internet Explorer receives Kerberos tokens at all times, and there's just some configuration missing, or it was ktpass.exe to be incorrectly executed. Here's how ktpass.exe was invoked: C:ktpass /out portal1.keytab /mapuser USER /princ HTTP/[email protected] /pass *

Getting error code -41 when copying files to external drive

- by diego

I'm having trouble copying some files from my mac to an external hard drive: I keep getting the nondescript "error code -41". I noticed some of the files with an additional "@" permission bit had the "com.apple.quarantine" flag set. I used the "xattr" command from this article What should I do about com.apple.quarantine? to take care of the quarantine flag and sort that out (these files were copied over from another mac on my network, so I guess OS X flagged them as quarantine). That took care of the problem for those files but I still have some that I can't manually copy over to the external drive. The only other thing I've noticed is that some of these files have a an extra permission bit: "drwxr-xr-x+" which I haven't been successful in googling. Aside from that I don't see anything else. Also, Disk Utility says everything's fine. Any help would be greatly appreciated.

Intel VTune Performance Analyser 9.1 not working on Win 7 64

Got the 32bit and 64 bit versions of the Intel VTune Performance Analyser. I installed the 64bit version (I think the installed was the "EMT" one) and when I go to create a new project, upon clicking the button to select an executable to profile, no file dialog popup shows. I got an old laptop and installed the 32bit on to Windows XP and it works fine. Regarding the 64 bit version, I did try changing the compatability to XP SP3 but it still didnt work. Does anyone know how to fix this?

New video card? [closed]

- by TutorialPoint

I ran into some problems with my ATI Radeon x1200. I want it to support vertex shader 3.0, but it only does 2.0. This is because Call of Duty: Modern Warfare 2 only works with 3.0. So, I want a new video card. Can someone help me, with a more clean look to it? I bet if I would stick to some seller, I would end up with a video card that does not support what I want, or is too expansive. I really do not want it to be above $75, if possible.

How do I remove the Refresh button from the Address toolbar?

- by Iszi

I like being able to run commands straight from my Task Bar. So, I've enabled the Address toolbar on my new Windows 7 system - just like I had on my old XP system. However, the bar seems to have a mandatory minimum length (I've posted a separate question about that) that's a bit longer than I'd prefer. Additionally, a bit more horizontal space is consumed by a Refresh button at the end of it. This Refresh button appears similar to the Go button that used to show by default in older versions. That button was easily removed by changing a registry value that doesn't seem to exist in Windows 7. Is there a similar registry hack I can use to remove the new Refresh button?

Setting up a shared media drive

- by Sam Brightman

I want to have a shared media drive be transparently usable to all users, whilst also sticking to FHS and Ubuntu standards. The former takes priority if necessary. I currently mount it at /media/Stuff but /media is supposed to be for external media, I believe. The main issue is setting permissions so that access to read and write to the drive can be granted to multiple users working within the same directories. InstallingANewHardDrive seems both slightly confused and not what I want. It claims that this sets ownership for the top-level directory (despite the recursion flag): sudo chown -R USERNAME:USERNAME /media/mynewdrive And that this will let multiple users create files and sub-directories but only delete their own: sudo chgrp plugdev /media/mynewdrive sudo chmod g+w /media/mynewdrive sudo chmod +t /media/mynewdrive However, the group writeable bit does not seem to get inherited, which is troublesome for keeping things organised (prevents creation inside sub-folders originally made by another user). The sticky bit is probably also unwanted for the same reason, although currently it seems that one userA (perhaps the owner of the mount-point?) can delete the userB's files, but not vice-versa. This is fine, as long as userB can create files inside the directory of userA. So: What is the correct mount point? Is plugdev the correct group? Most importantly, how to set up permissions to maintain an organised media drive? I do not want to be running cron jobs to set permissions regularly!

Font size of emacs in ubuntu

- by Ispinfx

I use emacs in ubuntu and I use Monaco 10 as its default font. However, the font rendering seems a bit odd compared to my gnome terminal with the same font size: It's a bit smaller and not as clear as that in the terminal. I've tried to avoid simply this with size 11 but it's too large for me. How can I make it the same as its look in the terminal ? Any help is appreciated :) UPDATE: I should tell you the above on is GUI emacs running a shell, and the below is the gnome terminal. On the right are their correspond font settings. Both 100% capture with font size 10: (left: emacs, middle: terminal, right: gedit) One more (gvim's):
