  • Why does plymouth start so late?

    - by Marky
    It appears that starting with 11.04 Plymouth starts so late in the boot process. Sometimes I only have a split second to see it before it transitions to the login screen. This is the same for 11.10. Compared to 10.04 and 10.10, Plymouth starts only a couple seconds or so after Grub and is very visible within the entire boot process. Is there something that can be done to have Plymouth run earlier? I have experienced this on 3 different machines and on 2 of these machines, I've been running Ubuntu since 10.04. So it's not just my notebook's hardware that is causing this. *One a side note, the boot process is one of the ugliest parts of modern Linux. Ubuntu is not excluded. After almost a decade, (I forget but was bootsplash the first?) this still has only been partly solved. For a couple of seconds ugly text is still seen when shutting down. On several ocassions, the same ugly text is seen when logging out of a session. It's never as smooth as you want it to be. Splash themes are great, don't get me wrong. It's just the transitions that are way off and you get glimpses of what's underneath. I'm used to this but for those new to Ubuntu and coming from Windows. It is a turn off.* pardon the rant. :)

  • how to design network for connectivity between private and corporate LANs?

    - by maruti
    there is a bunch of servers connected to shared storage in a private LAN (10.x.x.x). this privateLAN is managed by a windows server (DHCP, DNS and directory services) these hosts need to be from outside of the datacenter Eg. Remote desktop. can the NIC2 on each of the hosts be connected to the other public LAN (compromising speed or security? what are improtant considerations: additional hardware? like switches? routing&DNS software? currently available hardware : Dell Powerconnect 6224 switch .... planning this for storage network. software: windows 2003 server for DHCP, DNS, A/D ? would it be more flexible to use Linux distributions like IPCOP, Untangle etc? all that I am looking for is good isolation between private and other networks, avoid DHCP, DNS, AD clashes.

  • Windows 7 login automically puts "IIIII....." in password, so it is impossible for me to login?

    - by xaisoft
    I have no idea why this is happening. I have ran multiple malware programs, I have run anti-virus programs, I even restored to an early point in time. The keyboard letter "I" doesn't appear to be stuck, I am using an external keyboard by the way. When I reboot the computer and get to the login screen, when I press ctrl-alt-del to login, it the password textbox starts putting "IIIIIIIIIIII......", it only stops when I bang on the keyboard. I also noticed at one point that my caps lock on turned caps off and caps lock off turned caps on and some other weird behavior. I have tried search online for similar issues, but no luck.

  • Synchronizing 3 servers over IP

    - by user93078
    I'm setting up a medical server for a hospital that has doctors located in 3 different locations, meaning there would be 3 servers (1 in each location). All 3 servers would just have the following software: Ubuntu Server 12.04 minimal MySQL, PHP 5, Apache The medical software which would read/write to the MySQL database Remote admin apps like Nagios & Webmin Rsync for backup (rsync-over-ssh) as a cron job and the doctors at each location would access patient & billing data from their respective servers. What I'd like is, that each of these servers all have synchronized info (especially the mySQL database's) - let's say on an hourly basis each of these servers synchronize data to a common remote server and the data is then brought down to each of the servers. I know an easier way would be to have the medical app running on a remote web server, but since this is medical that we're talking about and knowing how common it is in our area for the net to go gown, I wouldn't like a web based scenatio. Is such a setup possible? Would this be the right way to do things or is there a better way to this? Would really appreciate views and comments (or how to set this up) on this.

  • Being rocked...

    - by ZacHarlan
    After almost four and half years, I finally escaped from the world of telemarketing.     I'm now at a place that writes really good code, values testing, does routine code reviews, collaborates with each other so continuously and effectively somebody should make a documentary about it!   Today alone, I had two really smart and well respected developers go line by line through my code and show me how to make it better.  Seriously, people pay really good money for something like this and they don't get near the quality of feedback as I got!     +1 for me finally getting to a point in my career where i get to work with some of the best of the best in the software world!   I've been rocked by the fact that places like this actually exist.     I've been Rocked by the sheer size, complexity and simplicity of our website.     Most importantly I've been ROCKED by the fact that this many smart people check their egos at the door, gel together and look for ways to make software better than how they found it.  This is how to grow a business with tech... hire great people and watch them go!   Seriously, bravo.

  • Video freezes when larger than a certain size

    - by Poyan
    I have a weird problem playing video files. I have a fairly new (a few years old) graphic card that should and has played up to 1080p video files without much a lot of trouble. I seem to be having a weird issue where the video plays back fine if the window is below a certain size, but as soon as the windowsize increases, the picture freezes. The audio still plays. Usually this is mitigated by killing som applications. Especially GTK (?) apps seem to cause this lag, like having a Nautilus window open usually triggers this error for me. With hardware rendering I get the error regardless of application. I have tried enabling software rendering in VLC and that eliminates the problem (but I get other problems using software rendering, so I've avoided it). I know this is pretty fuzzy, but I'm not sure how to approach this problem. Do you have any idea? EDIT: Some more information. I have the correct and latest drivers installed. My graphics card is a Nvidia 7600 GT.

  • Have to reset wireless frequently on iPad / Macs connected to Cisco WRV200

    - by retailevolved
    I have a Cisco WRV200 set up in our small office. The wireless signal works great for PCs, but I have found that Macs and iPads have to frequently reset the connection. It will be working for about 10 minutes, then stop. To fix it, I just turn off Airport and turn it on again. On an iPad, I have to go into settings, shut the wireless off, and then turn it on again. The router is broadcasting mixed B/G on channel 6. Security is WPA-PSK2. Anybody out there had similar issues with their router? How can I fix it?

  • "ant" is not recognized as command in Windows

    - by user1294663
    This is my first time developing Android applications. I'm developing an Android app on Eclipse on Windows 7. I would like to run the Android app from the Windows 7 command line interface. I have my Android device connected to the PC. The workspace directory that I use to store the Android project is C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I opened the command line interface and I changed the working directory to the Android workspace directory. cd C:\Users\Guest\Desktop\Software Applications Development\Java\Android Moblie Applications Projects\Eclipse Indigo for Java EE x64-bit\project workspace I included Android sdk platform tools directory into the PATH environment variable. c:\Users\admin\Android-sdks\platform-tools Then I entered this into the Windows 7 command line interface: ant debug I have this error message on the cmd: ant is not recognised as an internal or external command, operatable program or batch file. What is the solution to this problem?

  • How to programmatically control slave computer on BIOS level?

    - by PovilasSid
    I want to run some test on hardware level. My goal is to create or find a way to control one computer from another down to BIOS settings changing. For example: Master computer sends a signal for slave to restart and opens BIOS settings dialog. Master computer sends a signal to slave to change BIOS parameters and then restart. Then slave fully boots up master starts up some software on slave. Then software finishes operations cycle continues till certain conditions are met. I know that I am looking for a complex thing but mainly what I need are correct keywords because now I am being flooded by BIOS configurations tutorials. Main concerns: Is it possible without using any custom tailer chip? How can master monitor salve`s hardware activity? How to let master handled more than one slave? How what connections are needed to create this kind of setup? (cables)

  • Blocked port 25 on Windows 7 64 bit

    - by Michal Gow
    Strange problem. I have 2 computers connected to Wifi router. One with Windows Vista & second with 2 operating systems: SUSe Linux and Windows 7 64bit on it. Computer with Vista can connect to SMTP server of my email provider (and any other) using port 25, and can connect to a mail server using telnet mail.server.com 25 if this port is open. Computer with dual operating system can (using Linux) do the same. The same computer, with the same hardware (Wifi card etc.), and using the same WiFi router, cannot however use Port 25 and cannot Telnet into any smtp server. So the problem is in Windows 7. I did uninstall all antivirus software and disabled the firewall. The problem is still here. Is there way how find out which software is blocking this port?

  • Is there a common programming term for the problems of adding features to an already-featureful program?

    - by Jeremy Friesner
    I'm looking for a commonly used programming term to describe a software-engineering phenomenon, which (for lack of a better way to describe it) I'll illustrate first with a couple of examples-by-analogy: Scenario 1: We want to build/extend a subway system on the outskirts of a small town in Wyoming. There are the usual subway-problems to solve, of course (hiring the right construction company, choosing the best route, buying the subway cars), but other than that it's pretty straightforward to implement the system because there aren't a huge number of constraints to satisfy. Scenario 2: Same as above, except now we need to build/extend the subway system in downtown Los Angeles. Here we face all of the problems we did in case (1), but also additional problems -- most of the applicable space is already in use, and has a vocal constituency which will protest loudly if we inconvenience them by repurposing, redesigning, or otherwise modifying the infrastructure that they rely on. Because of this, extensions to the system happen either very slowly and expensively, or they don't happen at all. I sometimes see a similar pattern with software development -- adding a new feature to a small/simple program is straightforward, but as the program grows, adding further new features becomes more and more difficult, if only because it is difficult to integrate the new feature without adversely affecting any of the large number of existing use-cases or user-constituencies. (even with a robust, adaptable program design, you run into the problem of the user interface becoming so elaborate that the program becomes difficult to learn or use) Is there a term for this phenomenon?

  • Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

    - by Blankman
    I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.

  • Windows 7 does not 'wake up' from Sleep mode

    - by the watchmaker
    I'm new to Windows 7, so I don't know if this is normal. When the computer is idle for 30 minutes, the screen goes black and no key pressing or mouse movement will bring the computer out of standby. The computer is still running (fans and hard drive noise) but it will not respond and the screen remains black. The only way to get a response is to press and hold the power button until it goes off, then switch it back on. When it turns on it says "Resuming Windows" and then goes black again. Is this normal? Can the time-out delay be increased? Is there a better workaround than switching the PC on and off?

  • Problem with screen redrawing at DOS app in VmWare Player

    - by MicTech
    I have very old DOS Application (CadSoft Eagle - PCB Designer) and I want to work with it on my workstation with Windows 7. Then I install Windows 98 and that software into VmWare Player. But that software has serious problem with redrawing screen. It's very slow in comparison with my Intel Celeron 333MHz with Windows 98. I have same problem if I try to use DOSBox on Windows XP (same Celeron 333MHz). I also trying run this application directly on Windows XP (same Celeron 333MHz) with compatibility mod set to "Windows 98", but I get "(0Dh): General Protection Fault". Can someone give me good advice how I solve that?

  • What is the R Language?

    - by TATWORTH
    I encountered the R Language recently with O'Reilly books and while from the context I knew it was a language for dealing with statistics, doing a web search for the support web site was futile. However I have now located the web site and it is at http://www.r-project.org/R is a free language available for a number of platforms including windows. CRAN mirrors are available at a number of locations worldwide.Here is the official description:"R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R. R provides a wide variety of statistical (linear and nonlinear modelling, classical statistical tests, time-series analysis, classification, clustering, ...) and graphical techniques, and is highly extensible. The S language is often the vehicle of choice for research in statistical methodology, and R provides an Open Source route to participation in that activity. One of R's strengths is the ease with which well-designed publication-quality plots can be produced, including mathematical symbols and formulae where needed. Great care has been taken over the defaults for the minor design choices in graphics, but the user retains full control. R is available as Free Software under the terms of the Free Software Foundation's GNU General Public License in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows and MacOS."

  • how to remotely open an URL in Firefox in a specific profile?

I am trying to open an URL from a bash script to have it open in profile "test", like this: firefox -P "test" http://www.example.org/ However that opens it in profile "software" anyway. Any ideas?

  • I'm using a compatible active DisplayPort to DVI adapter with EyeFinity, why does my monitor still flicker?

    - by Christopher Galpin
    I specifically chose an active DisplayPort <- DVI adapter for use with EyeFinity right out of my graphic card vendor's list of confirmed compatible adapters. Yet the screen fails horribly, it blinks on and off constantly, sometimes the graphics go screwy and the appropriate resolutions won't be available. Sometimes the resolution will be available but I'll discover it's only with interlaced refresh rates and bounces up and down. I have to switch the resolution back and forth, again and again, to get it to work correctly, and then it fails again and the process must be repeated the moment the monitor is turned off or I reboot. It's maddening. What is wrong? Is my GFX card supplying insufficient voltage? (Firmware tweaks allegedly help some people, but my card's isn't modifiable.) Could the adapter be defective? Is it not "active" enough for my card and I need an expensive powered adapter? Is this endemic to DisplayPort in general?

  • Ubuntu on Samsung NP700Z5B - no Grub

    - by copolii
    I just bought a Samsung NP700Z5B laptop. Gorgeous machine and great performance! I do 2 things when I get a new laptop: Format the HD and install Winblows from a CD to ditch the bloatware Install some variant of Linux on it (lately Ubuntu) Step 1 worked fine (until earlier today), but I haven't been able to install Ubuntu on it for the past 3 days! I've tried Mint12, Ubuntu 12.04, Ubuntu 11.10, Ubuntu 11.04 and Ubuntu 10.04. The live CD and the installations all run fine and report no problems, but when I reboot grub is nowhere to be found! The system goes directly to Winblows! I've tried booting from the liveCD and re-installing grub via the chroot and purge & reinstall methods (https://help.ubuntu.com/community/Grub2) and neither makes a difference. I've also tried copying the boot sector: dd if=/dev/sda of=linux.bin bs=512 count=1 and putting it on c: then setting bcdedit to add the entry to the Windows bootloader with no results. Earlier today I decided to try and set my boot partition as an EFI boot partition ... bad choice, now I don't even have the Winblows boot loader. I've officially ran out of ideas. Tried calling Samsung, but they're closed (they'd probably say something stupid along the lines of "Samsung recommends Windows 7" ... I've had Dell say that to me). Any help would be greatly appreciated. Update 1 Tried re-installing 12.04 and now I get the screen continously turning off and back on, but still no sign of booting ... it has been doing it for 15 mins so far (I set the boot partition type to ext2 instead of ext4) Update 2 Well ... this just gets better and better. I inserted the installation USB key to reboot it and the flickering stopped for about a minute (remained on) then it started turning off and on again

  • What would be a good topic for research on "edge of multiple processors / computers programming" topic?

    - by Kabumbus
    This is a subjective discussion so we can express our dreams and hopes here. A "topic" must be like a task with point to have as end result a software poduct. A "topic" must be mainly about "Software engineering", "Algorithm and data structure concepts" and perhaps "Design patterns". I mean let us try to look what is not already there? What can be developed in fiew month and give a breakthrue / start a new leap / show somethig not realized before in science of f multiple computers programming? What i see is already there: LAN / wire and other infrastractural programms for connecting on device level MPI/ Bit torrent/Jabber protocols / APIs / servers for messaging on top Boost and analogs on evry OS in most languages for multithreading there are lots of CUDA like on computer frameworks for fast calculating on computers GPUs What I personally do not see out there is a crossplatform framework for multiple processes interaction. Meaning one that would allow easy creation of multyple processes running in paralell inside one hoster app on one machine. In level not harder than needed for threads creation (so no seprate server apps - just one lib doing it all) Is there ny such lib and what can you propose for research topic?

  • Entry level engineer question regarding memory mangement

    - by Ealianis
    It has been a few months since I started my position as an entry level software developer. Now that I am past some learning curves (e.g. the language, jargon, syntax of VB and C#) I'm starting to focus on more esoteric topics, as to write better software. A simple question I presented to a fellow coworker was responded with "I'm focusing on the wrong things." While I respect this coworker I do disagree that this is a "wrong thing" to focus upon. Here was the code (in VB) and followed by the question. Note: The Function GenerateAlert() returns an integer. Dim alertID as Integer = GenerateAlert() _errorDictionary.Add(argErrorID, NewErrorInfo(Now(), alertID)) vs... _errorDictionary.Add(argErrorID, New ErrorInfo(Now(), GenerateAlert())) I originally wrote the ladder and rewrote it with the "Dim alertID" so that someone else might find it easier to read. But here was my concern and question. "Should one write this with the Dim AlertID, it would in fact take up more memory; finite but more, and should this method be called many times could it lead to an issue? How will .NET handle this object AlertID. Outside of .NET should one manually dispose of the object after use (near the end of the sub)." I want to ensure I become a knowledgeable programmer that does not just rely upon garbage collection. Am I over thinking this? Am I focusing on the wrong things?

  • Encrypt shared files on AD Domain.

    - by Walter
    Can I encrypt shared files on windows server and allow only authenticated domain users have access to these files? The scenario as follows: I have a software development company, and I would like to protect my source code from being copied by my programmers. One problem is that some programmers use their own laptops to developing the company's software. In this scenario it's impossible to prevent developers from copying the source code for their laptops. In this case I thought about the following solution, but i don't know if it's possible to implement. The idea is to encrypt the source code and they are accessible (decrypted) only when developers are logged into the AD domain, ie if they are not logged into the AD domain, the source code would be encrypted be useless. Can be implemented this ? What technology should be used?
