• sudo: source: command not found

  - by HorusKol

  I've been updating some of the default profile for bash, and saw from the tutorials I was following that I could reload the new profile with the new environment settings by using: source /etc/bash.bashrc The only thing is - the new environment variables were only available to my current user - and were ignored when I used sudo. They only became available to sudo when I closed my terminal session and rejoined. When I try to use: sudo source /etc/bash.bashrc I get the error: sudo: source: command not found Is there a simple way to load in the new bash profile settings for sudo without having to close the terminal and restart?

• Unity iOS optimization and draw calls

  - by vzm

  I am curious of what methods I should approach in optimizing my Unity project for iOS hardware. I have very little image effects running (directional light with low res shadows) and I used the combine children script from the standard assets to lessen the load on the CPU. My project currently runs with 45-57 draw calls at non-intensive segments and up to 178 at intensive segments. I heard that static batching relieves some of the stress, but the game has the environment moving around the player instead of the player moving around the environment. Is there any alternative that I may look towards to improving the draw call number?

• Tp_smapi on Thinkpad T440

  - by user2597381

  I have a Thinkpad T440 with Ubuntu 14.04 (using i3wm). I have had trouble installing tp_smapi. I successfully installed it with dpkg -- can't remember whether I used apt or just downloaded it somewhere -- but I can't load the module. When I use modprobe on tp_smapi, I get this: "modprobe: ERROR: could not insert 'tp_smapi': No such device or address" Note that this is different from the error I get when I mistype the module name. I read somewhere that I might have to rebuild my kernel for it to work, but I'd thought that the kernel I was using (3.13.0-24) had that already set up. Has anyone gotten it to work? I hate how Lenovo manages the batteries!

• Best way for a mailing list in Android

  - by Asgard

  I want to create a mailing list function based on an address book included in the application, (NOT the user's contacts) for example I have the addresses [email protected] [email protected] [email protected] [email protected] [email protected] every email addresses, must be associated with a specific section, the various section should be selected through a checkbox list. every section may have more than an email. I have yet created a working email sender that support the simultaneous sending to many email but I don't know what is the best way to store and load the address in the application and how realize this.

• Boot problem with Ubuntu 11.10

  - by leonard

  So, I am an Ubuntu newbie, and I don't know a thing about it. I tried to install restricted extras (am I using it right?) through terminal, but it seems I failed :) maybe because during installation the internet connection crashed... anyway, I restarted and I got the Ubuntu intro screen at the boot, and then a black screen appeared with this information: checking battery state I restarted and it showed something else, so I rebooted for 5 times. Then a screen appeared *starting bluetooth *pulseaudio configured for per-user sessions saned disabled; edit /etc/default/saned I tried this: My fresh installation doesn't load. (PulseAudio problem) but didn't know how to save so I just skipped to update-grub, anyway nothing helped. What do I do?

• image viewer: png vs gif

  - by David Oneill

  I have a bunch of files that have .png extension. However, some of them are actually gif files. Any of the files, I can open them w/ gimp or view them in firefox, but when I try to open them with the Eye of Gnome viewer, it gives an error "Could not load image: Fatal error reading PNG image file: Not a PNG file" Is there: Another image viewer that can open files with incorrect extensions that I could use as default? It would need to have the ability to zoom in and out on images, and scroll through all the images in a folder via arrow keys. An automated way to rename the files that are actually gif files to the correct extensions? Choice 2 is preferred, but I don't now how to tell what type they are. I would be able to put together a bash script to do the renaming if there is a command that could tell me what type they are.

• Do you use to third party companies to review your company's code?

  - by CodeToGlory

  I am looking to get the following - Basic code review to make sure they follow the guidelines imposed. Security code analysis to make sure there are no loopholes. No performance bottlenecks by doing a load test etc. We have lot of code coming in from third parties and is becoming laborious to manage code reviews and hence looking to see if others employ such practices. I understand that it may be a concern for some and would raise the question "Well, who is going to make sure the agency is doing their job right?" But basically I am just looking for a third party who can hold all vendor code to the same standards.

• Take Two: Comparing JVMs on ARM/Linux

  - by user12608080

  Although the intent of the previous article, entitled Comparing JVMs on ARM/Linux, was to introduce and highlight the availability of the HotSpot server compiler (referred to as c2) for Java SE-Embedded ARM v7,  it seems, based on feedback, that everyone was more interested in the OpenJDK comparisons to Java SE-E.  In fact there were two main concerns: The fact that the previous article compared Java SE-E 7 against OpenJDK 6 might be construed as an unlevel playing field because version 7 is newer and therefore potentially more optimized. That the generic compiler settings chosen to build the OpenJDK implementations did not put those versions in a particularly favorable light. With those considerations in mind, we'll institute the following changes to this version of the benchmarking: In order to help alleviate an additional concern that there is some sort of benchmark bias, we'll use a different suite, called DaCapo.  Funded and supported by many prestigious organizations, DaCapo's aim is to benchmark real world applications.  Further information about DaCapo can be found at http://dacapobench.org. At the suggestion of Xerxes Ranby, who has been a great help through this entire exercise, a newer Linux distribution will be used to assure that the OpenJDK implementations were built with more optimal compiler settings.  The Linux distribution in this instance is Ubuntu 11.10 Oneiric Ocelot. Having experienced difficulties getting Ubuntu 11.10 to run on the original D2Plug ARMv7 platform, for these benchmarks, we'll switch to an embedded system that has a supported Ubuntu 11.10 release.  That platform is the Freescale i.MX53 Quick Start Board.  It has an ARMv7 Coretex-A8 processor running at 1GHz with 1GB RAM. We'll limit comparisons to 4 JVM implementations: Java SE-E 7 Update 2 c1 compiler (default) Java SE-E 6 Update 30 (c1 compiler is the only option) OpenJDK 6 IcedTea6 1.11pre 6b23~pre11-0ubuntu1.11.10.2 CACAO build 1.1.0pre2 OpenJDK 6 IcedTea6 1.11pre 6b23~pre11-0ubuntu1.11.10.2 JamVM build-1.6.0-devel Certain OpenJDK implementations were eliminated from this round of testing for the simple reason that their performance was not competitive.  The Java SE 7u2 c2 compiler was also removed because although quite respectable, it did not perform as well as the c1 compilers.  Recall that c2 works optimally in long-lived situations.  Many of these benchmarks completed in a relatively short period of time.  To get a feel for where c2 shines, take a look at the first chart in this blog. The first chart that follows includes performance of all benchmark runs on all platforms.  Later on we'll look more at individual tests.  In all runs, smaller means faster.  The DaCapo aficionado may notice that only 10 of the 14 DaCapo tests for this version were executed.  The reason for this is that these 10 tests represent the only ones successfully completed by all 4 JVMs.  Only the Java SE-E 6u30 could successfully run all of the tests.  Both OpenJDK instances not only failed to complete certain tests, but also experienced VM aborts too. One of the first observations that can be made between Java SE-E 6 and 7 is that, for all intents and purposes, they are on par with regards to performance.  While it is a fact that successive Java SE releases add additional optimizations, it is also true that Java SE 7 introduces additional complexity to the Java platform thus balancing out any potential performance gains at this point.  We are still early into Java SE 7.  We would expect further performance enhancements for Java SE-E 7 in future updates. In comparing Java SE-E to OpenJDK performance, among both OpenJDK VMs, Cacao results are respectable in 4 of the 10 tests.  The charts that follow show the individual results of those four tests.  Both Java SE-E versions do win every test and outperform Cacao in the range of 9% to 55%. For the remaining 6 tests, Java SE-E significantly outperforms Cacao in the range of 114% to 311% So it looks like OpenJDK results are mixed for this round of benchmarks.  In some cases, performance looks to have improved.  But in a majority of instances, OpenJDK still lags behind Java SE-Embedded considerably. Time to put on my asbestos suit.  Let the flames begin...

• GRUB2 panic: "No such partition"

  - by Android Eve

  I managed to install 10.04 on a system that already has 8.04 (separate partitions, of course). It also installed GRUB2 onto the MBR. After discovering that there is no menu.lst anymore, I edited /etc/grub.d/40_custom to point to where my other OS partitions are: menuentry "Ubuntu 8.04" { set root=(hd0,0) linux /boot/vmlinuz-2.6.24-28-generic initrd /boot/initrd.img-2.6.24-28-generic } menuentry "Windows 7 Ultimate 64-bit" { set root=(hd0,2) chainloader (hd0,2)+1 } GRUB2 displays the menu with those entries but when I select any of them, it refuses to load them, saying "No such partition". I know the partitions are there, as 10.04's "Disk Utility" sees them without any problem. How do I get GRUB2 to recognize them?

• Simple alternating text in Visual Basic 2008

  - by Josh Grate

  I have a simple completed program, but i would like to add one more feature to it but I'm not sure how. I have it set up to send a message automatically every 7 seconds when a text field is selected, repeating the message of course. What I would like for it to do is alternate between two separate messages, instead just repeating the one. I would like the new program to post at an interval of 12 seconds. Can you help me? Here is my coding. Public Class Form1 Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick SendKeys.Send(TextBox1.Text) SendKeys.Send("{ENTER}") End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Timer1.Enabled = True Timer1.Interval = (TextBox2.Text) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Timer1.Enabled = False End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Timer1.Enabled = False End Sub End Class

• Why is the dash so unresponsive, and is there a way to fix this?

  - by Jon

  I just upgraded to 12.04. When I press the super key to open the dash, there's a lag of 1-3 seconds before it displays, with no other programs running. (This is similar, but not identical, to the issue described in Dash application search unresponsive at startup about 11.10.) At login time, this lag is up to 10 seconds, and sometimes the dash doesn't respond at all to the super key. In contrast, the launcher Kupfer immediately responds to its hotkey, in milliseconds, and responds to my typing an application name also in fractions of a second. Is there a way to load the dash in memory or a RAM disk of some sort to make it more responsive?

• How to replace GRUB with BURG without overwriting MBR?

  - by StepTNT

  I'd like to install BURG but I don't want it to overwrite my MBR. That's because I've got two bootloaders in my system : Default Windows 7 in MBR Grub in /dev/sda2 With the first power button, it will boot into Windows and with the second button it boots from /dev/sda2, loading Grub and then Kubuntu. Now I want to replace GRUB with BURG. I've installed Burg with burg-install /dev/sda2 --force because I don't want my MBR to be overwritten (pressing the first power button MUST load Windows and avoid showing any sign of Linux). Setup was completed without errors, If I open burg-manager it loads my settings, allowing me to change them and to test everything with burg-emu, so I've changed my settings but the second power button still loads GRUB (Even a different version from the default Kubuntu one). How can I replace GRUB that's on /dev/sda2 with BURG and without overwriting MBR?

• How to crawl a webPage with dynamic content added by javascript

  - by blunderboy

  I guess there is a news that Google bots have the capability to understand our javascript code. It means this is possible to fully crawl a webpage which has lazy loading feature enabled. I am using Apache Nutch to crawl websites but I don't think it has the capability to fetch the URLs being injected in HTML page by javascript when the page is scrolled down. I see a lot of websites doing lazy loading for performance issue. So Can somebody please explain me how can i crawl the data which comes in HTML page on lazy load. (On scrolling the page down).

• Why does Live-USB boot freeze at the moving dots?

  - by Caleb

  I am currently trying to boot into Ubuntu 12.04 x86 using a USB. I used Untetbootin to do all that boot crap and what not. But for some reason Ubuntu wont load pass that screen with the dots and the purple background. What happens is the dots all light up once, then they go back to white then they all light up at the same time and then it just gets stuck there. Ive even tried using an x64 copy (since my CPU supports it) but have no luck with that either. Ive even tried different DISTRIBUTIONS of Linux and all have failed with loading. Please help

• How do I communicate with an IronPython component in a C#/XNA game?

  - by Jonathan Hobbs

  My XNA game is component-oriented, and has various components for position, physics representation, rendering, etc, all of which extend a base Component class. The player and enemies also have controllers which are currently defined in C#. I'd like to turn them into Python scripts, but I'm not sure how to interact with those scripts. The examples in Embedding IronPython in a C# Application suggest I'd have to create a wrapper class (e.g. a Script component) which compiles a Python script, and call the Update methods of the component in the script Is this the most effective way of working with a Python object? I feel that I'm missing something in my research - there must be a way to load up a script, instantiate a Python object and then work directly with it from within C#. Or is the wrapper required?

• Resize content for "frame" on .aspx page which draws product content from suppliers' page

  - by zenbike

  I have a retail store site, no online sales, which displays the webpage of our supplier in a "frame" in order to have the most accurate and up to date information for our customers. (example) My issue is that the size of the page it is pulling in doesn't fit in the frame. It looks pretty poor, and part of the content is obscured. Is there a way to scale the content drawn in to the size of the frame? The same site also has an intermittent issue with the Flash banner loading. When it doesn't load, the layout of the header on the page is awful. Any ideas there will also be appreciated.

• Unable to install 12.10 on asus r500v

  - by bmdr38

  I have been unable to get beyond the grub boot screen of the live dvd/usb. The Try Ubuntu without installing, Install Ubuntu, etc menu shows, and I have tried adding/replacing nomodeset and no splash with neither helping. Even "Check disc for defects" does not display anything when selected. I am at a complete loss as to how to fix this one. I have had many successful installs in the past, but this is definitely a first for me. Just as FYI, Gfx card: Geforce GT 635M I realize this particular card has Optimus on it, however even the alternative boot/command line install fails to load. Any help would be appreciated. I realize there have been multiple threads on this, but none of the methods within them have solved this yet. Thanks

• OSB, Service Callouts and OQL - Part 1

  - by Sabha

  Oracle Fusion Middleware customers use Oracle Service Bus (OSB) for virtualizing Service endpoints and implementing stateless service orchestrations. Behind the performance and speed of OSB, there are a couple of key design implementations that can affect application performance and behavior under heavy load. One of the heavily used feature in OSB is the Service Callout pipeline action for message enrichment and invoking multiple services as part of one single orchestration. Overuse of this feature, without understanding its internal implementation, can lead to serious problems. This post will delve into OSB internals, the problem associated with usage of Service Callout under high loads, diagnosing it via thread dump and heap dump analysis using tools like ThreadLogic and OQL (Object Query Language) and resolving it. The first section in the series will mainly cover the threading model used internally by OSB for implementing Route Vs. Service Callouts. Please refer to the blog post for more details.

• Question about Partitioning

  - by Trent C

  I am looking to dual boot Windows 7 and Ubuntu 13.10. I have been using windows for work and school for over a year, and have about 100 gig of stored files (backed up of course) and some paid programs. Because of this, I really want my partitioning experience to go well. Unfortunately, I am running into a bit of an anomoly When I load GPart, I see that my sda drive is unallocated http://i.imgur.com/Hi2XhIr.png Whereas my sdb appears to contain all of the windows files and partitions, and make up my C: drive http://i.imgur.com/aaCOXje.png Is this going to be an issue, as all literature on dual boot installation references sda? How do I work around it? System Info: Lenovo IdeaPad Y570- 750GB HDD with 64GB SSD Processor: Intel® Core™ i7-2670QM CPU @ 2.20GHz × 8

• Should we consider code language upon design?

  - by Codex73

  Summary This question aims to conclude if an applications usage will be a consideration when deciding upon development language. What factors if any could be considered upon language writing could be taken into context. Application Type: Web Question Of the following popular languages, when should we use one or the other? What factors if any could be considered upon language writing could be taken into context. Languages PHP Ruby Python My initial thought is that language shouldn't be considered as much as framework. Things to consider on framework are scalability, usage, load, portability, modularity and many more. Things to consider on Code Writing maybe cost, framework stability, community, etc.

• Why does sound stop working after a while?

  I don't know how to reproduce this problem, because I don't regularly play music or sound. All I know is that, sometimes, I'll load a video (from youtube or from a local file) and there will be no sound.

• How should I handle "real time" events in an online strategy game?

  - by Hojat Taheri

  Some online strategy games have real time events. For example when you send troops to attack somewhere, the attack happens at the right time in the future. Checking the database again and again to get the list of attacks happening each second would cause heavy load. Is there any technique to achieve this goal? Another example: You want to attack a village 3 hours away, you send troops and the attack occurs 3 hours later. Should there be an script to check the database at each second to run the query at the specified time?
