• Visual Studio 2010 on Macbook Air

  - by Kyle B.

  Does anyone here run Visual Studio 2010 (or VS12 RC) on a Macbook Air? I have the current model with 4GB ram, 13" screen, and 256GB SSD drive. Before I go through the effort of configuring this, I'd like to know if anyone from the community has done this and: Was the performance acceptable? If it is, I plan to get a larger cinema display monitor as a second display and do all my coding on this machine ditching my desktop. Did you use Boot camp, Parallels, or VMWare? I feel to maximize performance that boot camp would be necessary to make the most utilization of the memory, but am not sure if this completely necessary. I'd prefer to use a VM, but wasn't sure if this was practical and would value your input before buying a license. Did you also run anything else on the Windows installation, such as SQL Server express, IISExpress, etc? Did performance lag after a certain point? Note: I would have asked this in superuser.com, but felt this applied more directly to the programming community.

• Is there a SUPPORTED way to run .NET 4.0 applications natively on a Mac?

  - by Dan

  What, if any, are the Microsoft supported options for running C#/.NET 4.0 code natively on the Mac? Yes, I know about Mono, but among other things, it lags Microsoft. And Silverlight only works in a web browser. A VMWare-type solution won't cut it either. Here's the subjective part (and might get this closed): is there any semi-authoritative answer to why Microsoft just doesn't support .NET on the Mac itself? It would seem like they could Silverlight and/or buy Mono and quickly be there. No need for native Visual Studio; cross-compiling and remote debugging is fine. The reason is that where I work there is a growing amount of Uncertainty about the future which is causing a lot more development to be done in C++ instead of C#; brand new projects are chosing to use C++. Nobody wants to tell management 18–24 months from now "sorry" should the Mac (or iPad) become a requirement. C++ is seen as the safer option, even if it (arguably) means a loss in productivity today.

• C printf not working on ubuntu 13.10 terminal

  - by Blaze Tama

  First, im new in ubuntu so please bear with me. I need to create a C based program for a course in my university. I was using opensuse and its konsole when i was in the university's lab. So basically i need to install opensuse on my system or using a vmware. But i feel lazy to do that, so i tried to run it on my ubuntu instead of opensuse. However, no C code seems working on ubuntu's terminal. The compiling is success, but its not running, or at least the printf is not running. This is my code, a very very simple one : #include<stdio.h> #include<unistd.h> #include<stdlib.h> int main() { printf("test"); return 0; } When i compile it with gcc test.c -o test everything work fine and i get an executeable file. Then i try to run it by ./test, but the printf is not printed. No error or warning was shown. Am i missing something? Note : my gcc is the new one, it should has no problem. Thanks for your help :D

• Setting up dual monitors, Xorg.conf issues

  - by JTS

  I just got a new computer (W520, Graphics card nVidia GF106 [Quadro 2000]) and installed ubuntu on it using wubi. I have everything working, so I wanted to set it up to be able to use two monitors with an extended screen. I figured I had to edit Xorg.conf, but the file didnt exist. So I tried to create it by booting in recovery mode, and executing Xorg -configure but I am getting these errors: (EE) Failed to load module "vmwgfx" (module does not exist, 0) (EE) vmware: Please ignore the above warnings about not being able to load module/driver vmwgfx (++) Using config file: "/root/xorg.conf.new" (==) Using system config directory "/usr/share/X11/xorg.conf.d" (EE) [drm] No DRICreatedPCIBusID symbol Number of created screens does not match number of detected devices. Configuration failed. ddxSigGiveUp: Closing log Any idea how I can get Xorg -configure to work, so that I can have an xorg.conf file that I can edit to enable twinview? EDIT: Another way I could ask the same question to solve this problem is, why can't I boot with an xorg.conf file generated by nvidia-xconfig? Is there something in the generated xorg.conf file that might need editing?

• How to re-add RAID-10 dropped drive?

  - by thiesdiggity

  I have a problem that I can't seem to solve. We have a Ubuntu server setup with RAID-10 and two of the drives dropped out of the array. When I try to re-add them using the following command: mdadm --manage --re-add /dev/md2 /dev/sdc1 I get the following error message: mdadm: Cannot open /dev/sdc1: Device or resource busy When I do a "cat /proc/mdstat" I get the following: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [r$ md2 : active raid10 sdb1[0] sdd1[3] 1953519872 blocks 64K chunks 2 near-copies [4/2] [U__U] md1 : active raid1 sda2[0] sdc2[1] 468853696 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdc1[1] 19530688 blocks [2/2] [UU] unused devices: <none> When I run "/sbin/mdadm --detail /dev/md2" I get the following: /dev/md2: Version : 00.90 Creation Time : Mon Sep 5 23:41:13 2011 Raid Level : raid10 Array Size : 1953519872 (1863.02 GiB 2000.40 GB) Used Dev Size : 976759936 (931.51 GiB 1000.20 GB) Raid Devices : 4 Total Devices : 2 Preferred Minor : 2 Persistence : Superblock is persistent Update Time : Thu Oct 25 09:25:08 2012 State : active, degraded Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 Layout : near=2, far=1 Chunk Size : 64K UUID : c6d87d27:aeefcb2e:d4453e2e:0b7266cb Events : 0.6688691 Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 0 0 1 removed 2 0 0 2 removed 3 8 49 3 active sync /dev/sdd1 Output of df -h is: Filesystem Size Used Avail Use% Mounted on /dev/md1 441G 2.0G 416G 1% / none 32G 236K 32G 1% /dev tmpfs 32G 0 32G 0% /dev/shm none 32G 112K 32G 1% /var/run none 32G 0 32G 0% /var/lock none 32G 0 32G 0% /lib/init/rw tmpfs 64G 215M 63G 1% /mnt/vmware none 441G 2.0G 416G 1% /var/lib/ureadahead/debugfs /dev/mapper/RAID10VG-RAID10LV 1.8T 139G 1.6T 8% /mnt/RAID10 When I do a "fdisk -l" I can see all the drives needed for the RAID-10.

• How to prevent window list "confusion" when detaching eclipse views?

  - by amotzg

  I'm detaching eclipse views to float on my other screen in order to get more coding space on the first screen. When doing that, the detached windows appear in ubuntu's window list applet with the eclipse icon but with no title. Then, when pushing the main eclipse button on the window list, one of the detached views will get to front but not the main eclipse window. When using Alt+tab I can also see the extra eclipse icons but choosing the correct one for the main window works and make it the active window while also showing all detached childs. Other applications behave as expected, e.g. gimp floating panels don't show on the windows list and this is also the case with SlickEdit, Firefox child windows all show on window list but gets the focus correctly, etc. I can see the the workspace switcher show my two screens but in 'Monitor preferences' I see my two screens as one big screen. I'm working with ubuntu 10.04.4 under a VMware Workstation 7.1.3 build-324285. 'uname -a' output: Linux ubuntu 2.6.32-40-generic #87-Ubuntu SMP Tue Mar 6 00:56:56 UTC 2012 x86_64 GNU/Linux The desktop screen shot with the problem, ununtu's version, and Monitor preferences. How can I solve it and make only the main window show in window list or at least get activated when pushing it's button on the window list?

• JEOS

  - by john.graves(at)oracle.com

  JEOS stands for Just Enough Operating System.  It is  great environment for building virtual machines without all the clutter of a windowing system, games, office products, etc.  It is from Ubuntu and you install it using the Ubuntu server install, but rather than picking a standard install, press F4 and choose “Install a minimal system.” Note: The “Install a minimal virtual machine” is specific to VMWare and I plan to use VirtualBox. Be sure to include Open SSH in the install so that it installs sshd. *** Also, if you plan to install XE, you’ll need to modify the partitions to have a larger swap space (at least 1.5 G). *** Once the install is done, I find it useful to install a few other items. Update Ubuntu apt-get update Install some other tools apt-get openjdk-6-jre Yes, java will be included in any of the WebLogic installs, but I need this one if I want to do remote display (for config wizards, etc). apt-get gcc Some apps require to rebuild the kernel modules, so you’ll need a basic compiler. Install guest additions (Choose the VirtualBox Devices->Install Guest Additions…” option.  This sets up a /dev/cdrom or /dev/cdrom1.  You’ll need to manually mount this temporarily: sudo mount /dev/cdrom /mnt Then run the linux .bin file. Update nofile limits.  Most java apps fail with the standard ubuntu settings: edit /etc/security/limits.conf and add these lines at the end: *     soft nofile 65535 *     hard nofile 65535 root  soft nofile 65535 root  hard nofile 65535 These numbers are very high and I wouldn’t do this on a production system, but for this environment it is fin. To get rid of the annoying piix error on boot, add the following line to the /etc/modprobe.d/blacklist.conf file blacklist i2c_piix4

• Cannot Boot, How to recover

  - by Kendor

  Am running 11.10 64-bit with Gnome-shell. Something happened late Friday whereby my machine never gets to the login screen. I do get to an Ubuntu splash logo, after that I get a text screen that it hangs on. The screen is referring to issues with mounting various network resources, including VMWare and also some references to my NAS that are in fstab. If I hit "esc" I can get to the GRUB menu and into recovery console. If I try to do a file system check, I run into a similar error screen that I see when trying to boot normally. A possible clue here is that during my last good session I made some mods to the /etc/hosts file to reference another system which I'm connecting to with Synergy. I don't believe I have hardware issues as I'm able to boot properly with a Live USB and connect to my network/Internet. A few more tidbits. I have regular Dejadups backups on my NAS. I have a good Clonezilla whole drive image which is 4-6 weeks old.. My home is encrypted. I thought I'd try blowing away my hosts file via live USB, but when I mounted the hard drive everything was read-only and I couldn't figure out how to replace it. P.S. I logged in via CLI and modded the host file to remove the entry I'd made, to no avail. System continue to gets stuck on the following: CIFS VFS: default security mechanism requested. The default security mechanism will be upgraded from ntlm to ntlmv2 in kernel version 3.1s Would love some sober advice on how to attack this.

• Five years old Ubuntu system - dist-upgrades always went fine, however some tasks remain

  - by knb

  I have a PC with a current Ubuntu distribution installed. I've upgraded many times since 5.10. It always went well, however some tools or features were kind of left behind in a unsatisfactory state: grub to grub2 - is it an really necessary to switch the boot loader some time to grub2. Upgrading this scares me abit. I still have ext3 devices - is it worth upgrading to ext4? should I wait for btrfs? hibernation and suspend- it only worked in 5.10, since 6.04 it was messed up. Should I really care? Any chance to repair this myself? Simply by cleanup or hacking config files. It is a desktop PC after all. So energy saving functionality is not really needed. I am using vmware workstation 6.5 and the latest kernel that supports it is 2.6.32. This is my default kernel now, ignoring 2.6.35. Am I missing anything important in the new kernel now?

• One monitor getting spilled over into other monitor: how to do a 100% reset of gnome graphics configuration

  - by Paul Nathan

  I had to kill a VMWare process and afterwards, my monitor's configuration is buggy. I have 2 monitors in a side-by-side configuration. My right-hand monitor is the secondary monitor. Upon its right-hand side there are about 50 pixels showing from the left side of the lefthand monitor (ie, as if it was wrapped around). Further, my mouse clicks are registering as about 50 pixels sideways from where they should be. It's as if those 50 pixels between monitors got gobbled. What have I done? I've reset the screen configuration in multiple ways, using xrandr, multiple monitors app, etc. This persists in different side-by-side configurations, and also persists with another user. It does not occur with XFCE. Resetting the Window manager with the Compiz reset WM app does not fix this. I've concluded the burn-to-the-ground approach is likely the best, and would like to do a 100% reset of my graphics settings. It's an Intel integrated chipset. Removing ~/.config/monitors.xml did not work. Also, interestingly, the mouse can mouse-over the 50 errant pixels on the rhs of the right-hand monitor. I hypothesize that it's a compositing problem occurring at the layer where the background, selection, and clicks are caught. Also, inverting the right-hand monitor removes the issue, but renders the screen unusable. Even more datapoints: This happens in KDE as well Sometimes logging into Gnome and running xrandr --output DVI1 --auto resets it, but the issue immediately reappears when I press alt-tab. With Compiz Application Switch turned on, the workspace is 'pushed back' a bit, and the slice on the RHS follows it as well. I'm wondering if it's a flaw in the compiz workspace compositing configuration. I suspect the error was in the compositing configuration. I installed 11.10.

• Why won't my graphics work in Ubuntu 12.04 LTS?

  - by user170974

  I'm very new to Ubuntu and to Linux in general, and took the leap and formatted my PC to Ubuntu 12.04 LTS very recently :) I seem to be having some trouble getting my graphics card to run properly, I looked over what information I could find but I still cannot get it up and running and figured this was a good place to ask for help. The information I can find on my graphics is as follows: (Terminal command) lspci outputs: 01:05.0 VGA compatible controller: Advanced Micro Devices, Inc.

What is the correct way to install ATI Catalyst Video Drivers (fglrx)? Ubuntu Precise Installation Guide But it does not seem to work, since running fglrxinfo in terminal gives: display: :0.0 screen: 0 OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301) OpenGL version string: 1.4 (2.1 Mesa 9.0.3) What am I doing wrong here?

I did however reinstall ubuntu 12.04 LTS, and re-tried both with no success. Reintalling ubuntu did however fix the broken dependencies problems, etc.

Then why doesn't it show in the command to to show listening ports?

• Mirroring of Apps across servers

  - by user1038814

  We wish to host multiple apps across multiple servers. What we are looking for (ideally) is an existing solution which will work. For example, normally to do it we'd follow a route (for failover) like: App is installed on one server along with mysql database App is also installed on a second server. Rsync is used to mirror the files over to the second server and ensure consistency MySQL is installed with a Master-Slave setup. We use a service such as DNS Made Easy which has a DNS failover. If one server goes down it automatically routes traffic to the backup server We have done the above a few times and generally its fine. The issue I have here is that the above is for one app. What I would like to look at is how we can manage for multiple apps and if there is a layer (such as VMWare) that has complete mirroring built in at the OS level? For example how do web hosts currently do it when they ensure that more than one machine is running a bunch of hosted websites. If you were running hosting and you had 200 clients on a server you would want the same clients across 2 or more servers and want everything mirrored. Any advice would be much appreciated.

• Code Golf: Code 39 Bar Code

  - by gwell

  The challenge The shortest code by character count to draw an ASCII representation of a Code 39 bar code. Wikipedia article about Code 39: http://en.wikipedia.org/wiki/Code_39 Input The input will be a string of legal characters for Code 39 bar codes. This means 43 characters are valid: 0-9 A-Z (space) and -.$/+%. The * character will not appear in the input as it is used as the start and stop characters. Output Each character encoded in Code 39 bar codes have nine elements, five bars and four spaces. Bars will be represented with # characters, and spaces will be represented with the space character. Three of the nine elements will be wide. The narrow elements will be one character wide, and the wide elements will be three characters wide. A inter-character space of a single space should be added between each character pattern. The pattern should be repeated so that the height of the bar code is eight characters high. The start/stop character * (bWbwBwBwb) would be represented like this: # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # # # ### ### # ^ ^ ^^ ^ ^ ^ ^^^ | | || | | | ||| narrow bar -+ | || | | | ||| wide space ---+ || | | | ||| narrow bar -----+| | | | ||| narrow space ------+ | | | ||| wide bar --------+ | | ||| narrow space ----------+ | ||| wide bar ------------+ ||| narrow space --------------+|| narrow bar ---------------+| inter-character space ----------------+ The start and stop character * will need to be output at the start and end of the bar code. No quiet space will need to be included before or after the bar code. No check digit will need to be calculated. Full ASCII Code39 encoding is not required, just the standard 43 characters. No text needs to be printed below the ASCII bar code representation to identify the output contents. The character # can be replaced with another character of higher density if wanted. Using the full block character U+2588, would allow the bar code to actually scan when printed. Test cases Input: ABC Output: # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # # # ### ### # ### # # # ### # ### # # ### ### ### # # # # # ### ### # Input: 1/3 Output: # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # # # ### ### # ### # # # ### # # # # # ### ### # # # # # ### ### # Input: - $ (minus space dollar) Output: # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # # # ### ### # # # # ### ### # ### # ### # # # # # # # # ### ### # Code count includes input/output (full program).

• Changing the Android emulator locale automatically

  - by Christopher

  For automated testing (using Hudson) I have a script that generates a bunch of emulators for many combinations of Android OS version, screen resolution, screen density and language. This works fine, except for the language part. I need to find a way to change the Android system locale automatically. Here's some approaches I can think of, in order of preference: Extracting/editing/repacking a QEMU image directly before starting the emulator Running some sort of system-locale-changing APK on the emulator after startup Changing the locale settings on the emulator filesystem after startup Changing the locale settings in some SQLite DB on the emulator after startup Running a key sequence (via the emulator's telnet interface) that would open the settings app and change the locale Manually starting the emulator for each platform version, changing the locale by hand in the settings, saving it and archiving the images for later deployment Any ideas whether this can be done, either via the above methods or otherwise? Do you know where locale settings are persisted to/read from by the system? Solution: Thanks to dtmilano's info about the relevant properties, and some further investigation on my part, I came up with a solution even better and simpler simpler than all the ideas above! I have updated the answer below with the details.

• What do you mean by the expressiveness in a programming language?

  - by prosseek

  I see a lot of the word 'expressiveness' when people want to stress one language is better than the other. But I don't see exactly what they mean by it. Is it the verboseness/succinctness? I mean, if one language can write down something shorter than the other, does that mean expressiveness? Please refer to my other question - http://stackoverflow.com/questions/2411772/article-about-code-density-as-a-measure-of-programming-language-power Is it the power of the language? Paul Graham says that one language is more powerful than the other language in a sense that one language can do that the other language can't do (for example, LISP can do something with macro that the other language can't do). Is it just something that makes life easier? Regular expression can be one of the examples. Is it a different way of solving the same problem: something like SQL to solve the search problem? What do you think about the expressiveness of a programming language? Can you show the expressiveness using some code? What's the relationship with the expressiveness and DSL? Do people come up with DSL to get the expressiveness?

• Implementing Naïve Bayes algorithm in Java - Need some guidance

  - by techventure

  hello stackflow people As a School assignment i'm required to implement Naïve Bayes algorithm which i am intending to do in Java. In trying to understand how its done, i've read the book "Data Mining - Practical Machine Learning Tools and Techniques" which has a section on this topic but am still unsure on some primary points that are blocking my progress. Since i'm seeking guidance not solution in here, i'll tell you guys what i thinking in my head, what i think is the correct approach and in return ask for correction/guidance which will very much be appreciated. please note that i am an absolute beginner on Naïve Bayes algorithm, Data mining and in general programming so you might see stupid comments/calculations below: The training data set i'm given has 4 attributes/features that are numeric and normalized(in range[0 1]) using Weka (no missing values)and one nominal class(yes/no) 1) The data coming from a csv file is numeric HENCE * Given the attributes are numeric i use PDF (probability density function) formula. + To calculate the PDF in java i first separate the attributes based on whether they're in class yes or class no and hold them into different array (array class yes and array class no) + Then calculate the mean(sum of the values in row / number of values in that row) and standard divination for each of the 4 attributes (columns) of each class + Now to find PDF of a given value(n) i do (n-mean)^2/(2*SD^2), + Then to find P( yes | E) and P( no | E) i multiply the PDF value of all 4 given attributes and compare which is larger, which indicates the class it belongs to In temrs of Java, i'm using ArrayList of ArrayList and Double to store the attribute values. lastly i'm unsure how to to get new data? Should i ask for input file (like csv) or command prompt and ask for 4 values? I'll stop here for now (do have more questions) but I'm worried this won't get any responses given how long its got. I will really appreciate for those that give their time reading my problems and comment.

• Android Camera without Preview

  - by eyurdakul

  I am writing an android 1.5 application which starts just after boot-up. This is a service and should take a picture without preview. This app will log the light density in some areas whatever. I was able to take a picture but the picture was black. After googling like crazy, i came across a bug thread about it. If you don't generate a preview, the image will be black since android camera needs preview to setup exposure and focus. I've created a surfaceview and listener but the onSurfaceCreated event never gets fired. I guess the reason is, the surface is not being created visually. I've also seen some examples of calling the camera statically with MediaStore.CAPTURE_OR_SOMETHING which takes a picture and saves in the desired folder with two lines of code but it doesn't take a picture too. Do i need to use ipc and bindservice to call this function or do you have any suggestion to achieve my goal (taking a picture without preview) and if so, would you give me a small piece of code as example?

• Assistance with building an inverted-index

  - by tipu

  It's part of an information retrieval thing I'm doing for school. The plan is to create a hashmap of words using the the first two letters of the word as a key and any words with the two letters saved as a string value. So, hashmap["ba"] = "bad barley base" Once I'm done tokenizing a line I take that hashmap, serialize it, and append it to the text file named after the key. The idea is that if I take my data and spread it over hundreds of files I'll lessen the time it takes to fulfill a search by lessening the density of each file. The problem I am running into is when I'm making 100+ files in each run it happens to choke on creating a few files for whatever reason and so those entries are empty. Is there any way to make this more efficient? Is it worth continuing this, or should I abandon it? I'd like to mention I'm using PHP. The two languages I know relatively intimately are PHP and Java. I chose PHP because the front end will be very simple to do and I will be able to add features like autocompletion/suggested search without a problem. I also see no benefit in using Java. Any help is appreciated, thanks.
