• PC shuts down when installing ubuntu?

  - by Robin002

  I'm now using ubuntu from USB, and I'd like to install ubuntu on my hard disk. I tried the option of removing Vista while installing ubuntu. However, near the end of the installation process (presumably the end because I can see some slideshows on how to start using ubuntu), the screen suddenly goes to black with white words running around on it. Soon the computer shuts down. After that, restarting leads to a black screen with only a small white cursor on the top left corner. The cursor keeps blinking and nothing happens. I found that I can alternatively choose to boot with USB by hitting F12 just when the computer starts. So I tried to reinstall ubuntu by running ubuntu on USB. One of the options of installation is to update ubuntu 11.04 to ubuntu 11.04, so it seems the ubuntu is already installed somehow. Anyways, I tried both update and delete and install option but the same thing happens as the 1st time (sometimes before reaching the end), while I still cannot start my PC as ubuntu (without USB). How may I install ubuntu properly?

• frequent abnormal shutdowns/system crashes

  - by user110353

  It's been almost 5 days since I have installed Ubuntu and almost 6th time that my laptop has been crashed entirely and it shuts down abnormally. Actually, it heats up and I have to wait for 20 odd minutes before I can turn it on again. A message appears that my PC crashed due to overheating which may damage my hard disk. The crashes happened when I tried to open some application that freeze my PC not even giving me enough time to go to system monitor and end process. Sometimes the culprit application which caused crash is Ever-pad, sometime it's team-viewer, sometimes it's some other. This is something very serious. The last crash occurred at 09:14:40. Kindly click here to view system log. I want to stick to Ubuntu and the same laptop as I had serious issues with Windows and I nearly went out to dump my laptop and purchase a more powerful system. Below are my hw/os specs. Kindly advice on how to resolve this issue Ubuntu 12.10 Kernal 3.5.0-18-generic GNOME 3.6.0 Memory 2.0GB Processor: Genuine Intel CPU [email protected] x 2 Available Disk Space: 63.7 GB Thanks in advance

• Is there a way to make IETab always open a site in Internet Explorer?

  - by reg

  Hello, IETab offers a setting that lets you define sites that should always be opened using IE's rendering engine. This is great and I use it all the time. There are a few sites, though, with which I encounter problems when I access them this way (needless to say that these have some IE-only features, otherwise I would simply use Firefox without IETab). So my question is: is there a way to make IETab (or any other extension that does the same thing) automatically open a specific list of sites in IE? To be clear: I want a way to specify a list of sites that will open an external IE process from Firefox, when clicking on those links or bookmarks from within Firefox.

• F# &ndash; Converting your C# brain to the F# way

  - by MarkPearl

  My brain still thinks in C#!!! I have been looking at F# and trying to figure out the basics of it, but all the time in the back of my mind I am going – what is the C# equivalent to this or that… It’s frustrating because I almost want a F# to C# dictionary the whole time – and simply translate my C# code to F# – which would negate the main motivation for learning F# – as I want learn functional programming - if I was simply doing C# code in a F# syntax I would be gaining nothing! So I am experiencing pain while my brain forms some new neural networks… but luckily I live in a country where we have 11 official spoken languages, and plenty more unofficial languages so I have gone through the pain of learning how to speak a new language before – and I am finding the process is almost identical in learning a programming language that promotes a different way of looking at problems (from Object Orientated to Functional). That beings said… the first thing to learn is the basic syntax… I have searched the web for appropriate places to get a translation – and have been quite disappointed with what is out there for F#. Luckily, OCaml came to the rescue. There are some really good tutorials on getting started with OCaml syntax, one in particular that stood out was the OCamal-Tutorial. What I particularly like about it is that it is doing comparisons between C based languages and OCaml. Give it a read sometime – it’s well worth it and has definitely helped me understand F# a little better.

• I don't understand how TDD helps me get a good design if I need a design to start testing it

  - by Michael Stum

  I'm trying to wrap my head around TDD, specifically the development part. I've looked at some books, but the ones I found mainly tackle the testing part - the History of NUnit, why testing is good, Red/Green/Refactor and how to create a String Calculator. Good stuff, but that's "just" Unit Testing, not TDD. Specifically, I don't understand how TDD helps me get a good design if I need a Design to start testing it. To illustrate, imagine these 3 requirements: A catalog needs to have a list of products The catalog should remember which products a user viewed Users should be able to search for a product At this points, many books pull a magic rabbit out of a hat and just dive into "Testing the ProductService", but they don't explain how they came to the conclusion that there is a ProductService in the first place. That is the "Development" part in TDD that I'm trying to understand. There needs to be an existing design, but stuff outside of entity-services (that is: There is a Product, so there should be a ProductService) is nowhere to be found (e.g., the second requirement requires me to have some concept of a User, but where would I put the functionality to remind? And is Search a feature of the ProductService or a separate SearchService? How would I know which I should choose?) According to SOLID, I would need a UserService, but if I design a system without TDD, I might end up with a whole bunch of Single-Method Services. Isn't TDD intended to make me discover my design in the first place? I'm a .net developer, but Java resources would also work. I feel that there doesn't seem to be a real sample application or book that deals with a real line of business application. Can someone provide a clear example that illustrates the process of creating a design using TDD?

• Taking two actions in monit

  - by Oddthinking

  My monit script works to detect an outage with a process and inform me when the rule is: IF DOES NOT EXIST THEN ALERT My monit script works to detect an outage and automatically fix it when the rule is: IF DOES NOT EXIST THEN START But, what I want it to do is inform me AND fix it. Two rules in a row seems to make it ignore all but the last: IF DOES NOT EXIST THEN ALERT IF DOES NOT EXIST THEN START # No alert given. I could use a custom script that does both, and IF DOES NOT EXIST THEN EXEC "my_handwritten_script" but I was trying to move away from a mess of hand-written scripts towards a clean Monit configuration. Can I configure Monit to take two actions?

• Quitting a small start-up where you are a primary developer?

  - by programmx10

  Just curious to hear from other people who may have been in similar situations. I work for a small startup (very small) where I am the main developer for a major part of the app they are building, the other dev they have does a different area of work than I do so couldn't take over my part. I've been with the company 5 months, or so, but I am looking at going to a more stable company soon because its just getting to be too much stress, overtime, pressure, etc for too little benefit and I miss working with other developers who can help out on a project. The guy is happy with my work and I think I've helped them get pretty far but I've realized I just don't like being this much "on the edge" as its hard to tell what the direction of the company is going to be since its so new. Also, even though I'm the main dev for the project, I would still only consider myself a mid-level dev and am selling myself as such for the new job search. Just to add more detail, I'm not a partner or anything in the company and this was never discussed, so I just work on a W2 (with no benefits of course). I work at home so that makes it easier to leave, I guess, but I don't want to just screw the guy over but also don't want to be tied in for too long. Obviously I would plan to give 2 weeks notice at least, but should I give more? How should I bring up the subject because I know its going to be a touchy thing to bring up. Any advice is appreciated UPDATE: Thanks everyone for posting on this, I have now just completed the process of accepting an offer with a larger company and quitting the startup. I have given 2 weeks notice and have offered to make myself available after that if needed, basically its a really small company at this point so it would only be 1 dev that I would have to deal with... anyways, it looks like it may work out well as far as me maintaining a good relationship with the founder for future work together, I made it out to be more of a personal / lifestyle issue than about their flaws / shortcomings which definitely seems to help in leaving on a good note

• Can't install Ubuntu 12.04 64-bit on a dual-drive MacBook Pro 8,2

  - by kizdp

  Good afternoon, this is the first time I participate here as I'm new to Linux. I've been trying to solve the following problem for over a week without any sign of success so I hope there's a much more knowledgeable person here that can give me a solution. I have an early 2011 MacBook Pro (8,2) with Mac OS X running in a SSD. Then, instead of the Optical bay, I have a HDD in where I would like to install Ubuntu to run it natively. I've tried to do the normal installation process, with or without rEFIt, but it seems the problem resides on the communication between the device containing the Ubuntu .iso file and the laptop. It doesn't allow communication with the boot CD or USB drive. It usually says: “Loading bootlogo...” after I click on the “boot from CD, Linux Icon”. After trying several things, I would like to know if I could install Ubuntu on the HDD as an external HDD (using a friend's Window's system) and then simply put it back into my laptop so as to become an Internal HDD again. I guess, I would have to reinstall many drivers and so on, but would this approach work? Thanks in advance and sorry for this huge block of text

• How to install pgAdmin

  - by Kifsif

  I use Ubuntu 12.04 64 bit. At first I installed pgAdmin through Software Center. But it seemed old. So, I decided to uninstal it. Then I downloaded graphic installer for PostgresQL. sudo ./postgresql-9.2.1-1-linux-x64.run I was warned that a previous version of pgAdmin is found, it will be upgraded but I'll have to restart the server. Well, installation process worked. Then I turned out in terminal again. I restarted the server /etc/init.d$ sudo ./postgresql-9.2 restart /opt/PostgreSQL/9.2/pgAdmin3/bin$ ./pgadmin3 The answer is: The program 'pgadmin3' is currently not installed. So, I can't find my pgAdmin to launch it. Could you suggest me anything?

• Connect to a particular network connection from terminal

  - by RanRag

  I am currently using Reliance netconnect USB modem. The problem I am facing is my USB modem disconnects itself at 22:00 PM IST everyday. Now, sometimes what I do is start some downloading and leave my laptop for 2-3 hours in this case if my network disconnects it is a problem for me. So, what I used to do in windows is make a python script and execute rasdial myconnection_name to automate the connection process in my absence. Now I want to achieve something similar in linux. So, what are my alternatives for rasdial like tool in linux to automatically connect to a particular connection . I am using ubuntu 12.04 and here is my nm-tool output.

• Can I upgrade my ubuntu version and change to be primary OS after originally installing with Wibu?

  - by Garrick Wann

  I have recently installed Ubuntu 12.04 using Wubi 12.04 and I now wish to upgrade to a full installation of Ubuntu 14.04, Before attempting to upgrade through the update center I did some research on upgrading from a Wubi installation (alongside windows) to a full installation making Ubuntu primary and only OS and found that it is in fact doable through the update center however it is just highly recommended to perform a full backup before doing so. I have now finished backing up all the data I need to worry about and began the upgrade process through the update center and received the following error: Your graphics hardware may not be fully supported in Ubuntu 14.04. Running the 'unity' desktop environment is not fully supported by your graphics hardware. You will maybe end up in a very slow environment after the upgrade. Our advice is to keep the LTS version for now. For more information see https://wiki.ubuntu.com/X/Bugs/UpdateManagerWarningForUnity3D Do you still want to continue with the upgrade? My questions are as follows: A. Isnt 14.04 a LTS version??? B, What are your recomendations in order to ensure my graphics driver is installed correctly and im not stuck with bad configs/install?

• Fail to boot after installation onto ASUS PC 1015PX

  - by strugglingbadly

  My new ASUS 1015PX has the usual Windows on the SDA1 partition - 100Gb, followed by SDA2 - 15Gb - as the recovery partition for Windows, and SDA3 with 183Gb for drive D:\ for windows. ASUS uses SDA4 - 19Mb for it's own use. 11.10 on an USB will load Ubuntu on a try basis and it seems OK, but every time I attempt an install, Ubuntu quickly shuts down and the restart process begins. This repeats endlessly. I've tried 10.04 Netbook Remix but that will not boot at all with the machine reporting - unknown keyword in config file gfxboot vesamenu.c32: not a COM32R image. I've gone through the above about 6 times each with the same results. I have also tried the above with the partitioning unchanged, and using gparted, with SDA3 formatted to ext4, windows D:\ reduced to 8Gb providing a 175Gb unallocated space - all to no avail. Further information: During my attempt to load 11.10, I notice that on the page which offers 3 options of loading, the first in the list includes the statement 'install INSIDE windows...' whereas the on line help shows 'install ALONGSIDE windows...'. (my caps for emphasis) I have double checked that I am using the correct download - not the install within windows option.

• Determine compression ratio for Windows compressed drive

  - by munrobasher

  Is there a Windows 7 native way to display the overall compression ratio on a Windows compressed drive? As part of our disaster recovery process, we're copying some key system folders onto 2TB external hard drive, encrypted using TrueCrypt and copied using robocopy. The drive is compressed and I'd like to see what kind of compression ratio we're getting and whether it's actually worth the performance overhead. I know that TreeSize can possibly do this (as mentioned in another post) but want a OS native way if possible. Thanks, Rob.

• How to handle knowledge handover effectively?

  - by Zizzencs

  Let's say a large enterprise opens a new office in (insert random location here) and want the new colleges up to speed as fast as possible. Let's also say this enterprise is a very typical one with a complex environment, lots of history and almost full lack of documentation. What's already been decided is that the new colleges will receive howto-style documentation for the most typical tasks and will get seme architecture documentation for some of the more complicated systems. Any ideas about improving this process? And more specifically, how should such a howto document look like to be helpful?

• How do I disable startup dll and programs in vista?

  Here is the situation. I can't get into Vista or boot into safe mode. I get blue screened either way during the loading process. I would like to try to disable as many dlls and programs from loading at boot as I can. What files in vista do I change to go about doing this? All the guides I've seen do it from within Vista. I have a BartPE bootable cd that I'm using to get into the file system. I just need to know which files to modify. Thanks much for reading

• At what point does programming become a useful skill?

  - by Elip

  This is probably a very difficult question to answer, because of its subjectivity, but even a vague guess would help me out: Now that Khan Academy is beginning to offer Computer Science lectures I'm getting an itch to learn programming again. I maybe am a bit more technical than your average computer user, using Ubuntu as my OS, LaTeX for writing and I know some small tricks like regular expressions or boolean search for google. However from my previous attempts to learn programming, I realized I do not have a natural aptitude for it and I also don't seem to enjoy the process. But I am fairly certain that a basic proficiency in programming could prove to be very beneficial for me career wise; I also often get ideas for little scripts that I cannot implement. My question is: Let's say you study programming 1 hour / day on average. At what point will you become good enough so that programming can be used for automating tasks and actually saving time? Do you think programming is worth picking up if you never have the ambition to make it your career or even your hobby, but use it strictly for utility purposes?

• Cloning from a given point in the snapshot tree

  - by Fat Bloke

  Although we have just released VirtualBox 4.3, this quick blog entry is about a longer standing ability of VirtualBox when it comes to Snapshots and Cloning, and was prompted by a question posed internally, here in Oracle: "Is there a way I can create a new VM from a point in my snapshot tree?". Here's the scenario: Let's say you have your favourite work VM which is Oracle Linux based and as you installed different packages, such as database, middleware, and the apps, you took snapshots at each point like this: But you then need to create a new VM for some other testing or to share with a colleague who will be using the same Linux and Database layers but may want to reconfigure the Middleware tier, and may want to install his own Apps. All you have to do is right click on the snapshot that you're happy with and clone: Give the VM that you are about to create a name, and if you plan to use it on the same host machine as the original VM, it's a good idea to "Reinitialize the MAC address" so there's no clash on the same network: Now choose the Clone type. If you plan to use this new VM on the same host as the original, you can use Linked Cloning else choose Full.  At this point you now have a choice about what to do about your snapshot tree. In our example, we're happy with the Linux and Database layers, but we may want to allow our colleague to change the upper tiers, with the option of reverting back to our known-good state, so we'll retain the snapshot data in the new VM from this point on: The cloning process then chugs along and may take a while if you chose a Full Clone: Finally, the newly cloned VM is ready with the subset of the Snapshot tree that we wanted to retain: Pretty powerful, and very useful.  Cheers, -FB

• How can I re-create Microsoft Cluster Service resource groups on a different cluster?

  - by PersonalNexus

  I use Microsoft Cluster Service on a cluster of Windows Server 2003 machines containing several dozen resource groups. In the process of migrating to newer hardware, I would like move resources to the new machines on resource group at a time spread out over a few days to ease the migration and minimize risk. I was wondering of there was a smarter way to do this than manually re-creating resources on the new and then deleting them on the old cluster? The cluster has already been set up properly, the only missing is the resource groups and the resources they contain (IP, network names, services...). I have looked through the options of the cluster admin GUI and cluster.exe's commandline options, but haven't found anything like an import/export feature to copy over the configuration of a resource or entire resource group. Does something like this exist?

• Compilation of Etherpad fails in an OpenVZ VE

  - by ulf

  Hi everyone. I’m almost giving up, this will be my last try: I try to compile Etherpad on my OpenVZ server. It’s running a Debian 5.0 as the host system, in the VE I’ve got Ubuntu 10.04. I installed Etherpad in this VE with the instructions from the official Ubuntu Wiki: https://wiki.ubuntu.com/Etherpad. Everything runs fine until it comes to compilation. After calling bin/build.sh as described in the wiki the first steps are running fine. But then I’m running into a memory error: java.io.IOException: Cannot run program "cp": java.io.IOException: error=12, Cannot allocate memory Well, I understand the error message but don’t see the cause. The command free tells me that there’s plenty memory left in this VE: total used free shared buffers cached Mem: 2415236 1140872 1274364 0 0 0 -/+ buffers/cache: 1140872 1274364 Swap: 0 0 0 Beautiful. But even repeating the compilation process doesn’t bring me any further. Any help would be appreciated.

• Windows XP - non-user input data filter message after installing wireless keyboard & mouse

  - by James

  After I installed MS wireless keyboard and mouse and associated software, I started getting this annoying message titled "Hardware installation" telling me the software I am trying to install did not pass the XP logo tests. The software is for "HID non-user input data filter" and I have two options Continue anyway or stop installation. Now, if I try to continue the installation fails, if stop installing another message pops up with a little mouse logo and the whole process repeats itself. after I am done with that message a third dialog appears. This is happening every time I boot up my PC (a desktop), I tried following an advice I found in some forum and download windows update for ID non-user input data filter, but that installation failed as well. The thing is, that both keyboard and mouse are working fine Is there anyway to get past these dialogs ?

• Windows 7 Pro x64 suffering from insomnia

  - by gemisigo

  My Win 7 Pro x64 is unable to enter sleep mode. Pressing the sleep button results in strange state where the computer starts entering the sleep mode, the display is turned off but then the whole process stops, it does not switch off the hdd, the keyboard still responds to numlock/capslock, but the display does not on anymore. I have to cut power and restart. If I remove everything (wireless mouse, external hdd, usb hub, etc.) it does enter sleep mode, but if there is something left, it does not, though every one of them has "Allow the computer to turn off this device..." checked and "Allow this device to wake the computer" unchecked. Why does it not work? It was working properly in the RC.
