• 12.04 cannot boot from USB

  - by GhostRider

  The HP Pavilion g6 notebook is unable to boot from bootable USB stick created with Linux Live USB Creator. I was able to boot other systems using the same pendrive. I have changed the boot priority using F10. When I restarted, it didn't ask for any message like Press any key to boot from When I press F19, and selected the pendrive from the available options to boot from, while restarting it gives me a message: error while trying to boot selected boot image Though I looked into the possible suggestions here, none of them worked. Looking for any help? EDIT: I was able to fix the first issue, i'e ubuntu could be installed as secure boot option in the bios was not allowing the pendrive or cd/dvd to be detected. Now once i have successfully installed ubuntu 12.04, after the restart i was unable to find it in the os menu for selection and windows8 loaded by default Ubuntu version: 12.04

• After installing Ubuntu 12.10, Windows 8.1 disappears from start up menu

  - by Vaz

  I'm very new to Ubuntu (12.10), so I apologise if I'm not clear at any point! I had a Windows 8 (upgraded to Windows 8.1) and was fed up with it, so I converted to Ubuntu 12.10. I'd hoped to Dual Boot to at least get the benefit of both worlds. I created a partition for it in Windows and installed from a LiveUSB key (and installed into that parition). So now Ubuntu works great, but Windows 8.1 no longer shows up on the start up screen (where you theoretically pick which OS you want to boot in). I was going to try "Boot Repair" as mentioned here and restore MBR, but I don't want to start messing around with stuff I'm not entirely clear with. EDIT: For any of those who stumble here with the same problem, I just read here that a user wiped out his Windows partition by accident... I checked my own computer with sudo fdisk -l and there's only one Device Boot (dev/sda1). I'm not an expert, but I'm guessing that means Windows has been written over.

• System response times --- A good Service Level Agreement?

  - by mpeterson

  In order to view system performance, I have been asked by management to give page response times for a few key pages. I want to make sure I am giving a good picture of the overall health of the system, and not just narrowing in on a single measurement. So my question is: When developing software, what metrics would you provide to your stakeholders to indicate a system that is healthy and running well? (if it is not running well, that should also be evident! Not trying to hide/obscure any problems.)

• How should I expand Jenkins to help me release? [closed]

  - by Amy Worrall

  Pushing new Sparkle releases of our internal apps is a pain. I have to make the build, make the release notes file, sign the .zip with the private key, and add a new entry to the appcast file tying everything together. I'd love it if Jenkins could help: use the commit messages for the release notes, and automatically do the rest of it. Should I be looking at writing a new Jenkins plugin, or using shell scripting, or is there something already that will do what I want? (A quick Google didn't find anything.)

• How to install a new CA certificate on Linux?

  - by Dail

  I have bought a cheap SSL certificate to run my website using NGINX. They sent me 4 .crt files: www_mywebsite_it.crt AddTrustExternalCARoot.crt PositiveSSLCA.crt UTNAddTrustServerCA.crt I have configurate www_mywebsite_it.crt and my .key on NGinx, but I also have to install the others .crt files. How can I do it? I'm using Ubuntu. (The problem is that I see correctly the SSL certificate using Firefox, Chrome and Opera but if I use Firefox 4.0.1 (the last) I get the default Firefox alert for insecure website.) Thank you!

• cryptsetup partitions not detected at boot

  - by Luis

  I installed a fresh 12.04 and tried to mimic what I had for 10.04. swap should be encrypted with a urandom key and there's another partition that will contain home and other directories. # cat /etc/crypttab | grep -v '^#' | grep -v '^$' cryptswap /dev/sda5 /dev/urandom swap encriptado /dev/sda6 # grep -e 'cryptswap' -e 'encriptado' /etc/fstab /dev/mapper/cryptswap swap swap defaults 0 0 /dev/mapper/encriptado /encriptado ext4 defaults 0 0 I also apt-get install cryptsetup When I boot, the system says (try to translate) that either the partition is not found or is not ready. I should wait, press M for manual or S to jump over. What am I missing here?

• Programmer, software engineer, computer scientist What's the difference? [closed]

  - by ForgottenKahz

  Possible Duplicate: What are the key differences between software engineers and programmers? What's the difference between computer science and programming? Whats the difference between a Software Architect, a Software Engineer, and a Software Developer (Programmer)? What is the actual difference between Computer Programmers and Software Engineers? Is this description accurate? What's the difference between computer science and programming? I want to know the difference between a programmer, a software engineer and a computer scientist. I'm new to the scene and I don't want to step on anybody's toes. I once gloated to a programmer that I was learning MS Access. Boy, was that a mistake. But when my father in law contracted some of his work out to software engineers their code was junk. In the world of software development, who goes by what title? Does it matter?

• Alt + # shorcut, how to remove?

  - by Qocko

  Being a World of Warcraft player, I use keyboard combinations to cast spells and "alt + #" is one of the combination, # being the key just before the 1 2 3 4 [...], under "escape" and on top of "tab" (I have a "French(canada)" keyboard). I've searched in the keyboard options, the shorcuts parts and I found nothing, I even tried to assign it randomly, hopping it'll overwrite the real shorcut but it didn't. When I press "alt + #" I have a "alt + tab" like but just for one type of window. For exemple it'll make me navigate through many instances of folder, but it won't switch to another application. It just cycle through the open windows of one application. Help me get rid of this annoying shorcut please ! Thanks in advance.

• How do I add pcie_aspm=force to my boot options?

  - by nargo7

  I just upgraded to 11.10 from 11.04 on my laptop (I don't have Windows) by downloading from the Ubuntu website. The laptop battery is in bad condition, but I was using it with the 11.04 plugged to AC all the time, and everything was fine. After installing 11.10, the laptop seems to not notice that it is connected to AC, so it shuts down a few minutes after starting. I read that I have to type pcie_aspm=force in the boot command, so I tried accessing it by pressing the "F6" key while booting, and then the other F keys, but nothing happened. I also found that I can write that instruction in the terminal window, but I don't know in which file or location. I would appreciate some help, but I am not a computer engineer, so please write the instructions in plain English.

• How to change keyboard sleep button to hibernate?

  - by Allu2

  I have a keyboard with a "sleep" button that does indeed make my computer go to sleep. The problem is that Ubuntu can't really handle sleep on my computer, causing it go into a non-responsive mode, having the CPU fan spinning at full speed and it stops receiving any input. Hibernation instead works mainly as it should. I would like to set the sleep key to hibernate, but the keyboard settings' hotkeys tab doesn't have this "sleep" keybinding and though I could make new one with hibernate --force as the command, it would require root rights to run. How can I change the keyboard sleep button action to hibernate?

• Domain held at one registry, need to redirect to subdomain on my own hosting provider

  - by Glinkot

  Hi, There are lots of questions around this general area, but I haven't seen one that exactly mirrors what I'd like to know. It's per the title really. My understanding (and what I'm told by my host) is the easiest thing is just to get the transfer key and bring the DNS across to my own hosting provider. Also I'm told by my host this doesn't affect the client's ownership of the domain itself. Basically, I have a subdomain setup with the site (this has the same IP address as the top level domain). So presumably just giving the other registrar that IP address will only refer it only to the TLD rather than the subdomain. What's the easiest way to achieve this? It's an asp.net site, I don't have a hosted directory on the client's account where I can code a redirect. Thanks all Mark

• Need to test .properties one by one in every possibility?

  - by ??? Shengyuan Lu

  For example, there are some key-value configuration in .properties file. Such like someFeatureEnable=true. It must be bool type value which will be parsed by framework, in my case it's typical Java Spring configuration. Spring will handle the configuration and throw Exception when users set someFeatureEnable=123. My question is: if there many properties in .properties file, Is it worth testing them one by one? It's quite troublesome and low priority. The .properties file is always configured by tech administrator stuff. Limited chances that they will mess up the configuration. Thanks!
