• Help reinstalling Ubuntu on macbook pro

  - by pipsqueaker117

  Ok. I recently installed ubuntu on my macbook pro. Unfortunately, while trying to install the nvidia graphics drivers the system wouldn't reboot, the screen grey for hours. I concluded that I had broken ubuntu, and proceeded to boot into osx and remove the ubuntu partitions. After I had done that, after a reboot, I noticed that "boot linux from hd" was still listed in the bootloader (i'm using rEFIT). I dismissed it. Now, I'm trying to reinstall ubuntu, using the same USB that I successfully installed with earlier. Now, however, when the ubuntu installer is on the "copying files" part this error (more or less) pops up. ERRNO 5: We're sorry, the installer crashed. This error frequently is caused by faulty installation media, the hard disk being too hot... and so on and so forth. I'm not sure what's causing the problem, but I have a hunch that whatever's the reason that's causing linux to show up in rEFIT is the root reason. If anyone could respond, that would be great. PS, and unfortunately no, i do not have a time machine backup.

• Should I use my real name in my open source project?

  - by Jardo

  I developed a few freeware programs in the past which I had signed with my pseudonym Jardo. I'm now planning to release my first open source project and was thinking of using my full real name in the project files (as the "author"). I thought it would be good to use my name as my "trademark" so if someone (perhaps a future headhunter) googles my name, they'll find my projects. But on the other side, I feel a bit paranoid about disclosing my name (in the least case I could be getting a lot of spam to my email, its not that hard to guess your private email from your name). What do you think can be "dangerous" on disclosing your full name? What are the pros and cons? Do you use your real name or a pseudonym in your projects? I read this question: What are the advantages and disadvantages to using your real name online? but that doesn't apply to me bacause it's about using your real name online (internet discussions, profiles, etc.) where I personally see no reason to use my real name... And there is also this question: Copyrighting software, templates, etc. under real name or screen name? which deals with creating a business or a brand which also doesn't apply to me because I will never sell/give away my open source project and if someone else joins in, they can write their name as co-author without any problems...

• Tips for Making this Code Testable [migrated]

  - by Jesse Bunch

  So I'm writing an abstraction layer that wraps a telephony RESTful service for sending text messages and making phone calls. I should build this in such a way that the low-level provider, in this case Twilio, can be easily swapped without having to re-code the higher level interactions. I'm using a package that is pre-built for Twilio and so I'm thinking that I need to create a wrapper interface to standardize the interaction between the Twilio service package and my application. Let us pretend that I cannot modify this pre-built package. Here is what I have so far (in PHP): <?php namespace Telephony; class Provider_Twilio implements Provider_Interface { public function send_sms(Provider_Request_SMS $request) { if (!$request->is_valid()) throw new Provider_Exception_InvalidRequest(); $sms = \Twilio\Twilio::request('SmsMessage'); $response = $sms->create(array( 'To' => $request->to, 'From' => $request->from, 'Body' => $request->body )); if ($this->_did_request_fail($response)) { throw new Provider_Exception_RequestFailed($response->message); } $response = new Provider_Response_SMS(TRUE); return $response; } private function _did_request_fail($api_response) { return isset($api_response->status); } } So the idea is that I can write another file like this for any other telephony service provided that it implements Provider_Interface making them swappable. Here are my questions: First off, do you think this is a good design? How could it be improved? Second, I'm having a hard time testing this because I need to mock out the Twilio package so that I'm not actually depending on Twilio's API for my tests to pass or fail. Do you see any strategy for mocking this out? Thanks in advance for any advice!

• Attempting to install ubuntu 11.10

  - by Orin

  I installed version 9 sometime ago and since have forgotten the process for partitioning, or the layout is different. I have 5 partitions but only have windows xp installed on the pc in question with that being the one of those 5 partitions which is ntfs 34444 mb its - a 40gig hard-drive. My first question is... is there a way to get a screen shot of the partitioner when I am running the demo session straight from disc... these 5 partitions are fragmenting the other 4ish gig needed to install.. I get an error message which says go back and make sure 1 partition has at least 2.5 gig or so. But I have no idea what I am supposed to set these remaining 4 partitions to in order to proceed.. I have read up on install guides and understand that one must be "/" root and another as swap... but to no avail thus far have the correct combo. A few screen shots will no doubt help you guys answer as I'm baffled as to what specific details to give as each one has various settings on inspection, and I don't really feel like writing it all down manually then posting specs for each one

• Poor performance after reinstalling to a USB drive

  - by anonymous

  I am currently running Ubuntu 11.10 off of a SanDisk 16GB USB. I installed it using a Live USB with the following partition configuration: 6GB Primary /dos FAT32 5GB Logical / ext4 5GB Logical /home ext4 I don't have a hard disk, and don't see myself getting one anytime soon. I rely solely on this 16GB, and two other 4GB USBs, one of which I used as the LiveUSB. I bring the USBs around, and even use the install at work. I previously used an install that used a swap file. It functioned fine for the most part, save for a few slow moments, but I came across this post, and it got me thinking about my USB's life, so I reinstalled with the current config. My problem now is that it is slower. Applications like Firefox would hang more often. In my previous setup (the automatically partitioned setup), Firefox would start hanging if I was running an unzip or install task on the same partition as /. Now however, it would hang if I had another window open i.e. the system settings window. My guess is that it may have something to do with the swap file or the install being on a Logical partition rather than a Primary partition, but I don't know. Any insight as to why it has slowed down?

• Configuring network to set wlan0 as primary

  - by Sheed

  I recently had to rebuild my pc and decided to go for ubuntu 14.04. I think the mistake I made was I started from a 12.04 install disk instead of the 12.10 disk I'd used previously and when given the option set my primary connection as ethernet (because the wireless option didn't work). After upgrading to 14.04 etc, I managed to get the wireless working, or more using steps like ifconfig -a and the likes I managed to prove that the wireless card etc. is all installed and working. However every time I boot without a hard wired connection plugged in I get the message "waiting for network configuration". I can then once it's booted without a network get my wirless working using sudo ifconfig wlan0 up iwlist wlan0 scan This seems to kick the wireless module into life and it appears in the GUI and I can then select a network, however all the options like edit network and disconnect etc are all greyed out. What I would like of course is if the WLAN0 was just set as my primary default network so I've been looking for a solution to this and it would seem that I need to adjust the old /etc/network/interfaces file but when I try to do so using the sudo vi /etc/network/interfaces command I, well I simply have no idea what I'm doing. Other than that typing :q! gets me out of there before I do to much damage! As far as I can tell (by navigating to the file in the GUI) the output of my /etc/network/interfaces is as follows: (obviously not including the " in each line that's just to break the heading rule of the #) "# This file describes the network interfaces available on your system "# and how to activate them. For more information, see interfaces(5). "# The loopback network interface auto lo iface lo inet loopback "# The primary network interface auto eth0 iface eth0 inet dhcp If this is the case then this clearly doesn't contain what it should do but I don't how to fix it. Nor do I even know if I'm on the right track. Any help would be appreciated thanks :)

• Just installed Ubuntu 12.04. When booting, all I get is a black screen with cursor

  - by user66378

  Installation appears to go fine. After rebooting, I get my motherboard loading screens, but when it comes time for Ubuntu to boot, I just get a black screen with a blinking white underscore in the top-left - same as I got when waiting for the install CD to load, except it lasts forever. The only keypress it seems to recognize is ctrl+alt+del, which reboots. Letters don't register, function keys w/ or w/o modifiers do nothing. I've installed Ubuntu 12.04 twice and got the same error. The first time, I installed it as the only OS, and had it take up the whole disk. The second time, I installed Windows 7 first, then Ubuntu by specifying custom partitions. After this install, it would boot straight to Windows without showing grub. I used EasyBCD to add the Ubuntu installation to grub, and this got grub to show, and let me select it, but it led back to the same error described up top. I've had Linux Mint 11 and 12 installed on this PC, but was unable to get previous versions of Ubuntu to install (always had errors while installing, not after). Hardware: Intel Core i7-2600K Sandy Bridge 3.4GHz (3.8GHz Turbo Boost) LGA 1155 ASUS SABERTOOTH P67 (REV 3.0) LGA 1155 Intel P67 SATA 6Gb/s USB 3.0 ATX Intel Motherboard EVGA 01G-P3-1371-TR GeForce GTX 460 (Fermi) CORSAIR Vengeance 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Western Digital RE4 WD5003ABYX 500GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive

• how to deal with controller mutations

  - by Milovan Zogovic

  During development process, things are constantly changing (especially in early phases). Requirements change, UI changes, everything changes. Pages that clearly belonged to specific controller, mutated to something completely different in the future. For example. Lets say that we have website for managing Projects. One page of the website was dedicated to managing existing, and inviting new members of specific project. Naturally, I created members controller nested under projects which had proper responsibility. Later in the development, it turned out that it was the only page that was "configuring the project" in some way, so additional functionalities were added to it: editing project description setting project as a default ... In other words, this page changed its primary responsibility from managing project members to managing project itself. Ideally, this page should be moved to "edit" action of "projects" controller. That would mean that all request and controller specs need to refactored too. Is it worth the effort? Should it be done? Personally, I am really starting to dislike the 1-1 relationship between views and controllers. Its common situation that we have 1 page (view) that handles 2 or more different resources. I think we should have views completely decoupled from controllers, but rails is giving us hard time to achieve this. I know that AJAX can be used to solve this issue, but I consider it an improvisation. Is there some other kind of architecture (other than MVC) that decouples views from controllers?

• Battery life low on notebook using ubuntu 11.10 vs. windows 7

  - by les

  Im using a brand new Dell XPS notebook (bought mar 2012) which has 4.5 hrs battery life using a 6 cell battery-when i use windows 7. The machine uses an Intel core 17 2670qm processor, and a 64 bit operating system. I downloaded Ubuntu 11.10 and installed it on a USB drive, which is how i use it. I still have Windows 7 on the machine. When the machine is booting up I hit F12, and run Ubuntu from the flash drive instead of the machine booting Windows, as it normally would. On the Ubuntu menu, on the top right area, there is a battery menu, which shows how long to charge battery, or how much life left etc..with a fully charged battery the most Ubuntu will give me is 1.5 hrs. I've adjusted all power setting etc by clicking on the battery meter where i can make these adjustments, and have even turned down the brightness on the monitor. I've read through these questions here, and a user wrote to install Ubuntu 12(?)(the alpha version) when it's out this month(april), and this has better power management. Other forums (Ubuntu wiki) state that windows 7 controls power management effectively because it's configured to work with the hardware. I'd like to install Ubuntu and wipe windows but can't because of this issue. I need my notebook to go hours, not an hour and a bit. Can anybody recommend possibly a good software to use, that will work with the machines bios under Ubuntu? Another thought of mine, is- since I didn't yet wipe windows off my hard disk, is windows still possibly controlling the power mgmt aspect on the machine? I've thought of calling tech support at Dell and asking for help there, maybe Dell has something (a tweak?), I can download that'll work under Ubuntu. Looking forward to any help/suggestions i can get here, i'm really stuck on this..

• How to Boot or "enter" into ubnutu 11.04 (Natty Narwhall) on PS3 after installing it?

  - by Xdm

  After failing to install ubuntu 11.04 Desktop version (burned on a dvd, because iso's file size was 726 Mb), in tried the alternate version (about 686 Mb) which i burned into a CD. During the installation process, i manually partitioned the hard drive using ext3. After the installation, the CD ejects itself and i hit "continue". In the k boot prompt i hit "enter" on my the keyboard. I see i welcome message in a dark background (a kind of full screen terminal/console called CLI i think) and was asked to enter my user name and password. After that, instead of booting into the beautiful desktop of Ubuntu, i saw this: ubuntu@my_name$ It was like a line of command i think, where you can use "sudo" commands. It is called a non-graphic mode i think. My my REAL problem is to enter Ubuntu 11.04 with the chocolate-colored background and the African music drum. I tried many commands to boot into the graphic mode of the system such as Ctr+Alt+F7 but nothing happened. In this case, i just saw numbers showing available blocks. I DON'T UNDERSTAND. I also tried startx and sudo startx without result. I DO bought a PS3 BOTH for gaming and for Ubuntu because i can't afford buying a PC. Please help me with my trouble dear Ubuntu 11.04 users. I am counting on you. All the best Xdm

• Dual monitor, permission issue

  - by cenna75

  I had a dual monitor configuration going on for quite some time. One day, after moving the computer to another location and reconnecting everything, it changed such that I saw everything in double (being very much sober), I think it's called the 'mirrors' config. Anyway, from there on, there was nothing to be done through the system settings gui to change it back, as it wouldn't allow me to save any modification. The error I get when clicking 'save' is : "Failed to create file /home/me/monitors.xml.xxxxxx. Permission denied", xxxx being a random code, changing everytime. However, I can save all the configurations I want just fine by using the terminal, in my case: xrandr --output DVI-I-1 --right-of VGA-1 So I do have a workaround and this is therefore a question more out of curiosity. What could possibly have changed to make it impossible to do it through the gui and still letting me change the config using xrandr without being root? I'm having a hard time believing it could have anything to do with disconnecting/reconnecting the monitors... Any idea? Thanks !

• Good quality Secure Software Development Training [closed]

  - by Patrick

  Just had my annual appraisal and found out my company is willing to pay for training and exams etc! Woohoo (they kept that one quiet). I'm interested in doing a course on secure development techniques. Has anyone got any suggestions for good quality distance learning courses in secure development (I could probably get a couple of days off to attend a conference/ course if required)? We're mostly an MS .Net house but I have no particular allegiance to MS or any other programming language (though, obviously, C++ is the best language in the world). I have 12 years development experience working in (what are now) PCI:DSS environments, including designing and developing a key management system and I have some knowledge of basic attacks (XSS, injection etc). I would prefer a hard course I struggle with to a basic course I learn 3 things from (but hopefully get something right at my level). A quick google found these two course which look good: http://www.sans.org/course/secure-coding-net-developing-defensible-applications https://www.isc2.org/csslpedu/default.aspx I don't really know how to choose between them, and finding other courses isn't going to make that job any easier, so I thought I'd ask those who know. EDIT : Hmm, care to share the reason for your down vote, will help me learn how to use the site better...

• Dual Booting WIndows 7 and Ubuntu 12.04

  - by mfes

  I have Windows 7 32 bit installed on a 64 bit Laptop. I am trying to install Ubuntu 12.04.I am trying to install Ubuntu 12.04 using USB. I created the bootable usb using live usb installer. I have 6 partitions in Windows 7 of which in Windows 7, I created a partition of 50 GB and also having an unallocated space of 50 Gb. I will install Ubuntu 12.04 in any one of these space. When I am booting from USB and selecting the option of "Try Ubuntu" and In Ubuntu desktop, when I click "Install Ubuntu 12.04" , and choosing the option as " Something Else " ( I dont want to Install Ubuntu alongside Windows or want to erase Windows totally ), only 3 paritions getting listed. One is system memory reserved as 100 mb. Second is C drive and third partition is listed as a whole space ie remaining space of the entire hard disk is listed instead of partitions. I tried Gparted Editor and it also lists the same as Ubuntu 12.04 So whats the problem and how can I make the Ubuntu to detect all the partitions so that I can install in the unallocated space or in the 50 GB Partition ? ( P.S - When I try the same in my 32 bit desktop, it is detecting all the partitions )

• The very beggining research for web developing

  - by stckxchng

  It is a general question to ask what would be the easiest way to start a website, however every one need a little boost up at the begging. There are content management systems, or admin panels, or some people have developed their own systems and many more diffirent things people use at the very beggining. Among others my way was looking for a very lightweight cms and develop a system on to it, unfortunately I couldn't find a good system to develop on, for example I decided to develop on snewscms (the lightest weight cms) but it is really hard to manage since it is not developed with object oriented programming standarts and I thought it would be a mistake to continue developing on to such a system. On the other hand starting to code from the core would be weak about security, and using a massive cms like joomla or drupal will not be good since there will be many things that are unused and moreover I will not feel well when I don't know what I am controlling since it is not easy to know every part of them. What I am asking is what would you do if you had lost all the files you are currently using today, where would you start from? What tool would you use? Or is there a lightweight and well coded tool to get start with?

• For photography use, is Unity is overheating my laptop? Should I try OpenSuse instead?

  - by SoT

  I am a perfect noob here in the Linux world. Previously was using Windows 7. Mine is an HP laptop - Intel core2duo T5470 @ 1.60GHz × 2 / 965GM with 2GB RAM. I installed Ubuntu 12.04TLS and is quite liking it's display. I really recognized it is 3D before knowing it was Unity 3D interface. My uses are image editing, home uses, downloads, browsing etc.. No video-editing/gaming at all. Being a Photography enthusiast I use image editing programs fairly more. But I am now feeling my laptop is getting a bit overheated - processor and hard-disk. I tried lm-sensor and could not make out much of it. Installed Xsensors.7. It gives the same output as lm-sensors gave me. It gives temperature for 4 things Temp1, temp2, temp3, and temp4. For "acpitz". Please guide me in this. However I wanted to ask something more. Which one is better for working with images - photography I mean - openSUSE 12.1 or Ubuntu with unity 3D? Can I get the display quality with the openSUSE distribution? I heard for laptops openSUSE uses power more efficiently, is there any truth? Please suggest me whether I should try openSUSE or not. If so with which GUI? KDE or GNOME? Thanks in advance. Regards SoT

• How do I install Kodos in 12.10?

  - by Brutus

  In previous Ubuntu version I used Kodos extensively. But the package has been dropped in 12.10. It's a neat regular expression testing tool. It's hard to find an alternative that is not Windows only (or Air, or uses action script which bails on more complicated RegEx, or works in Wine - well kinda, but not really..., etc.). So I tried to install Kodos from source, which seems to work (download sourceball and setup.py) but it won't run because of missing PyQT dependencies (that I can't manage to fulfill with anything install-able trough standard packages). I then tried to install PyQT manually (which seems to require manual install of SIP and QT too) and instead of pip I have to use configure.py and qmake. It throws error after error at me. I tried to overcome one after another for over an hour but no luck. It even managed to break Calibre and Music Brains Picard. So I purged all the stuff, reinstalled python-sipand python-qt4 from the standard packages and gave up. Has anyone managed to get Kodos running on 12.10? Or any hints on how to do it?

• Problem installing Ubuntu 14.04 into a laptop using Windows 8.1

  - by AlexanderFreud

  I have used Ubuntu on my LG laptop for several years. I lately bought an Acer Aspire V5 laptop which included Windows 8.1. I don't have any data on it; I would like to just remove it completely (that horrible Windows 8.1) and install Ubuntu. I tried using a USB device with Ubuntu 14.04 (64bit version) saved on it. I changed the BIOS configuration, putting USB device first on boot order, Windows Boot Manager last. When I try to run with USB device it doesn't work. Messages like these show up: System doesn't have any USB boot option. Please select other boot option in Boot Manager Menu. Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. insert your windows installation disc and restart your computer 2. choose your language settings, and then click "next" 3. click "repair your computer" If you do not have this disk, contact your system administrator manufacturer for assistance File \ubuntu\winboot\wubildr.mbr Status: 0xc000007b Info: the application or operating system couldn't be load...[?] required file is missing or contains errors. Could someone please write step-by-step procedures to install Ubuntu 14.04 after removing Windows 8.1 ? I already have done a second partition on the hard disk just in case.

• Is this a b43 driver problem?

  - by Nullet

  I have 13.04 on a Dell Inspiron 1564 with Broadcom 4312 WiFi card. The wl drivers cause kernel panic on linux-3.8 so I succesfully installed the b43 driver a couple of months ago. Now I have changed ISP and got a new router, and the connection drop when downloading software from internet to a 2008r2 using Remmina Client, and apt-get install on virtual machines in virtualbox. I have no idea why this suddenly became a problem.. My phone does not loose the connection, just Ubuntu. Output from /var/log/syslog after lost connection rfkill list(after disconnecting): 0: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes I can use NetworkManager to disable wireless and then enable wireless to connect again. rfkill ublock all/wifi/0 removes only Soft blocked. lshw -C network *-network description: Wireless interface physical id: 4 logical name: wlan0 serial: 78:e4:00:78:d2:05 capabilities: ethernet physical wireless configuration: broadcast=yes driver=b43 driverversion=3.8.0-32-generic firmware=478.104 ip=10.0.0.3 link=yes multicast=yes wireless=IEEE lspci 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01) After waking from suspend and when booting, it takes about 40 sec to get network connection.

• Upgraded from ubuntu 12.04 to 12.10 issues

  - by ubuntu novice user

  I recently upgraded 12.04 to 12.10 ubuntu and then all hell broke loose. Being more specific, I have a Compaq machine and its hard disk is partitioned into 3 parts, so when I installed Ubuntu 10.04, I installed it in windows, since then have upgraded with each new ubuntu release via the update manager without any problems. I have installed the 64 bit versions. 12.10 downloaded via update manager, and initial downloading of packages was without problems, however, as it tried to install the packages, error messages appeared. The first was one about missing lib files, but I clicked to continue, since I am a relative novice on ubuntu. It continued, and during the restart process, when it was powering down, the computer hanged on the shutting down bit without rebooting for more than half an hour, so I manually shut down the machine and restarted it. Then a new error message appeared stating could not find disk, and I hit the manual fix option, and it now boots to an empty ubuntu desktop with my wallpaper but no launcher and the graphics appears as if this was put on a 640 x 480 resolution, and the screen no longer fits onto my 19" LCD. I had to use Ctrl-Alt-T to log out and then restart from there. How can I resolve this issue. Please help!

• What would be your thoughts in this situation?

  - by craftsman

  Imagine there's a businessman who has a solid internet idea. He hires you as his first employee and pays you well (also offers you shares if product generates revenue). You code the product for more than a year. But the product is not properly marketed and left almost unused. You get frustrated by loneliness and working endlessly on an unused product. You start applying at different companies. You don't get response from anyone. After a month, you realize that things are beginning to change. The businessman has started to give more attention to the product. You have defined a solid marketing plan with him. Things are almost sure to work. Suddenly one day, you get a call from a big company you yearned to work for. They invite you for an interview. If you respond to the interview and get the job, you will lose the chance to earn something from your one year hard-work. If you don't respond, you will obviously miss the chance to work in the big company. If your marketing doesn't work as well (you will know it in a couple of months), you will probably not get a chance in the big company again. What would be your decision?

• Can an Employer turn you down if you have said the fact about current work culture being bad [closed]

  - by MansonRix

  I had recently an interview where I scored good in 1st two round of technical interview . Then in the 3rd round was the managerial round where the guy started about my experience and whether I have vaptured any requirement and handled and trained any teams. This went pretty well for around 50 mins . Then there was the awkward question , Interviewer: why amI looking for a change? Me: coz I want to explore my carrier options? Interviewer: But your current company is big enough and you can explore options over there? (This was supposedly the trap) Me: Apart from that I am missing the flexibilty of working with Us and Europe based company as my current company is not that flexible. Interviewer: What exactly you don't find flexible. Me: The login time . Even if you get late by 1sec you might have to explin. Though this is not a big problem , still I will prefer flexibilty as we are working really hard. Interviewer: Allright ( Then couple of more questions) , Hope to C U Ya , that's pretty much it . Now I called up HR and they say , they are yet to get the feedback from Interviewer. Did I screw it? I mean does some one really have to pretend always by saying positive things about company and manager though not saying negative things?

• C# calendar needs Business Logic for real-time reminders? [on hold]

  - by lazfish

  I am not a super experienced C# user, though I have some experience in .Net and VB.Net. Just got this new job and my first assignment is a mission critical part of the business. It is pretty important I get it right so I was hoping for some sage advice. We have created a calendar using jQuery, C#, .Net & SQL Server 08. The calendar works but now we are wanting to add email, SMS and voice-call reminders. We are a small company and can do whatever we need to do with no restrictions on our IT environment. I have some base-line experience with Unix servers but would prefer to stay in the Micro$oft universe if it is prudent to do so. I know how to add the API calls and services to initiate these reminders (using built in email services for email and Twilio.com for SMS). I am asking for advice about how to approach a reliable and timely listener service that knows when to call the service or API for the reminder before an appointment. EG. SMS: "You have a conference call in 30 minutes." I have done some research, but it is hard to know what is a proven reliable approach. What I am looking for is an experienced opinion on a good (or the best) strategy for implementing a solution that will reliably listen for appointments and dispatch the reminders when needed.
