• Hard Drive Formatting and Unmounting Errors

  - by Lucas Carther

  I'm trying to format a hard drive using Ubuntu 11.10. Every time that I attempt to format it from the Disk Utility, I get the error saying the device is busy, and under details it says: /dev/sda1 is mounted Then when I try to unmount it from the disk utility, it shows that the operation has failed and says: Error unmounting: umount exited with exit code 1: helper failed with: umount: only root can unmount UUID=70D6-1701 from /boot/efi

• Cloning a dual boot system from HDD to SSD

  - by Alex

  I'm planning on replacing my laptop's HDD with a 256GB SSD, but I have a dual-boot (12.04 and Windows 7) setup and I'd like to be able to directly migrate Ubuntu over without having to reinstall and lose all of my settings. GParted reports the following partition setup on my HDD. I am, of course, able to modify it if necessary. /dev/sda1 (NTFS) 66.92 out of 200.00 MB used I'm honestly not sure what this partition is for. Maybe for Windows 7 system files? I'm hesitant to mess with it. (edit; it turns out it is a partition for Windows recovery files in the event of OS corruption, so I don't want to remove it. Plus it also appears to be a major pain to remove anyways) /dev/sda2 (NTFS) 116.35 out of 339.06 GB used (boot) This partition is the C:/ drive on my Windows installation. I don't use it on my Ubuntu installation, except it is the boot partition and thus has grub on it. /dev/sda4 (extended) > /dev/sda5 (ext4) 14.49 out of 91.34 GB used > /dev/sda6 (linux-swap) 5.92 GB These are my Ubuntu partitions. /sda5 contains my documents and all of the files I use on Ubuntu, and (as far as I know) the system files for Ubuntu itself (it's the partition I created when prompted by the Live-DVD installer). /sda6 is, of course, the swap partition which I only need for hibernation (6GB of RAM). /dev/sda3 (NTFS) 9.89 out of 14.75 GB used This is an annoying partition that Lenovo created to store some drivers and files that I might need later on. For example, it allows me to use OneKeyRecovery for a quick factory recovery if absolutely necessary, not sure if that'll work on an SSD. It also contains not-so-important files for bloatware installation. In total, my HDD only has about 150GB of files on it so it should fit comfortably on the SSD. The problem is, I want to exactly migrate my files, partitions, OSes, MBR, etc. from my HDD to my SSD and I'm not quite sure how to do this. I've seen CloneZilla referenced before, but I'm not all too experienced and the documentation for it quite frankly seems a bit like a foreign language to me. So, put simply, is there any way I can exactly clone this HDD to an SSD without a massive headache? Also, if it matters, I'll probably be using an external hard drive case (as recommended in online tutorials) to externally attach the SSD to my laptop during the cloning process due to the lack of two hard drive slots in the machine.

• migrating product and team from startup race to quality development

  - by thevikas

  This is year 3 and product is selling good enough. Now we need to enforce good software development practices. The goal is to monitor incoming bug reports and reduce them, allow never ending features and get ready for scaling 10x. The phrases "test-driven-development" and "continuous-integration" are not even understood by the team cause they were all in the first 2 year product race. Tech team size is 5. The question is how to sell/convince team and management about TDD/unit testing/coding standards/documentation - with economics. train the team to do more than just feature coding and start writing test units along - which looks like more work, means needs more time! how to plan for creating units for all backlog production code

• Is OOP hard because it is not natural?

  - by zvrba

  One can often hear that OOP naturally corresponds to the way people think about the world. But I would strongly disagree with this statement: We (or at least I) conceptualize the world in terms of relationships between things we encounter, but the focus of OOP is designing individual classes and their hierarchies. Note that, in everyday life, relationships and actions exist mostly between objects that would have been instances of unrelated classes in OOP. Examples of such relationships are: "my screen is on top of the table"; "I (a human being) am sitting on a chair"; "a car is on the road"; "I am typing on the keyboard"; "the coffee machine boils water", "the text is shown in the terminal window." We think in terms of bivalent (sometimes trivalent, as, for example in, "I gave you flowers") verbs where the verb is the action (relation) that operates on two objects to produce some result/action. The focus is on action, and the two (or three) [grammatical] objects have equal importance. Contrast that with OOP where you first have to find one object (noun) and tell it to perform some action on another object. The way of thinking is shifted from actions/verbs operating on nouns to nouns operating on nouns -- it is as if everything is being said in passive or reflexive voice, e.g., "the text is being shown by the terminal window". Or maybe "the text draws itself on the terminal window". Not only is the focus shifted to nouns, but one of the nouns (let's call it grammatical subject) is given higher "importance" than the other (grammatical object). Thus one must decide whether one will say terminalWindow.show(someText) or someText.show(terminalWindow). But why burden people with such trivial decisions with no operational consequences when one really means show(terminalWindow, someText)? [Consequences are operationally insignificant -- in both cases the text is shown on the terminal window -- but can be very serious in the design of class hierarchies and a "wrong" choice can lead to convoluted and hard to maintain code.] I would therefore argue that the mainstream way of doing OOP (class-based, single-dispatch) is hard because it IS UNNATURAL and does not correspond to how humans think about the world. Generic methods from CLOS are closer to my way of thinking, but, alas, this is not widespread approach. Given these problems, how/why did it happen that the currently mainstream way of doing OOP became so popular? And what, if anything, can be done to dethrone it?

  - by Hjke123

  Ok I have recently made some mistakes with installing some operating systems that I should have just kept on a live cd not ubuntu but another os and with my ocd when I saw my lot's of different partitions I just wanted to reset my computer so it boot's up and doesn't load any os and I have to put in my ubuntu live cd and install that and that would be my only os on this computer so I want to know how I can just wipe my entire hard drive so when it boot's I get to put my live cd in and start anew?

• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduct from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that dividing up a program into more function improves its design is a common thing taught at school, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• Wubi installation: I get os freezes which make me have to hard reboot

  - by user54774

  Wubi installation has been going a success for me, but one problem is that I get freezes, My Mouse works I can move it round but I can't click or right click. Sometimes my keyboard works and so I can shutdown safely using commands, but other times the keyboard doesn't work. One example of this is when I was running minecraft and youtube. and to off the laptop the only way was to hard reboot. Does anyone have a solution to this?

• Hard link not works under MacOS in GUI mode

  - by AntonAL

  Hi, i faced a little strange behavior, while using hard links. From terminal, i create a text file 1.txt and a hard link "to this file" nano 1.txt mkdir dir ln 1.txt ./dir/ I check the resulting hard link and see, that it's contents is the same, as of "original" file. less ./dir/1.txt I change the initial file ... nano 1.txt ... and see, that changes was reflected in hard-link less ./dir/1.txt I change content of hard-link (more correct, of course - file, being referenced with hard-link) ... nano ./dir/1.txt ... and see, that changes are reflected in initial file less 1.txt Until now, all going well... Now, I close terminal and start playing with created files (1.txt and ./dir/1.txt) from Finder. When i change on this two files with TextEdit, changes are not reflected in another file. Just like the hard link was teared off... Whats going on here ?

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• How to setup Thinkpad features on Thinkpad T500

  - by gijoemike

  I have a IBM-Lenovo Thinkpad T500. I was previously a exclusive windows user, but recently installed ubuntu and loving it because of speed and interface. The only thing is that I don't get some features that I came to enjoy in windows. I need help setting these up: Hard-drive protection - active protection software that pauses drive when there is movement My printer doesn't work (can't find the driver for this one): canon Ip2600 A way to change which graphics chip to use while in OS. I have both the integrated and non integrated (dual-graphics). (If not easy to setup, I know there's a way to do it before it boots, but don't know how). CPU performance level - in windows you can pick "high performance", "power saver", etc.. to save batteries. My integrated camera w/light - it works but need an app where I can record videos, take snapshots, etc. can't find one that works. Thanks!

• USB install from second internal hard drive in a MacBook Pro

  - by aaron.anderson

  I am trying to install Ubuntu (among others) on a second internal hard drive on my MacBook Pro. I have an 80 GB internal SSD with OS X on it, along with a 750 GB internal HD with a few partitions, one of which being for Ubuntu. I currently have rEFInd installed for switching between the OS's. I was wondering how one would go about installing Ubuntu from the USB install stick. I have followed the instructions on creating a bootable USB. Once this is bootable, could I just hold the Option key on startup, and it should appear in the menu? Or am I missing something?

• Wifi won't enter working net after hard reboot

  - by Terry Smith

  I rebooted the hard way after my system jammed again because FF eats all the ram. (that's a different problem) I've always gotten away with it, but not this time. The system came up ok BUT it absolutely refuses to log onto the local house wifi net. I know the net is ok as the Windows box I'm writing this on is on it right now. I deleted the connection and rentered the password but it will not go on. /var/lib/NetworkManager/NetworkManager.state says everything is turned on. I know this is my fault but I'd really like to get back on the net. The machine is a Toshiba Satellite. Any suggestions?

• Get Unity to read in objects name without the need to hard code

  - by N0xus

  I'm trying to get away from having to hard code in the names of objects I want my code to use. For example, I'm use to do it this way: TextAsset test = new TextAsset(); test = (TextAsset)Resources.Load("test.txt", typeof(TextAsset)); What I want to know, is there a way to have so that when I drag my test.txt file onto my object in Unity, my code automatically gets the name of that object? I'm wanting to do this so once I write the code, I don't need to back in and change it should I wish re-use it.

• A Good Developer is So Hard to Find

  - by James Michael Hare

  Let me start out by saying I want to damn the writers of the Toughest Developer Puzzle Ever – 2. It is eating every last shred of my free time! But as I've been churning through each puzzle and marvelling at the brain teasers and trivia within, I began to think about interviewing developers and why it seems to be so hard to find good ones.  The problem is, it seems like no matter how hard we try to find the perfect way to separate the chaff from the wheat, inevitably someone will get hired who falls far short of expectations or someone will get passed over for missing a piece of trivia or a tricky brain teaser that could have been an excellent team member.   In shops that are primarily software-producing businesses or other heavily IT-oriented businesses (Microsoft, Amazon, etc) there often exists a much tighter bond between HR and the hiring development staff because development is their life-blood. Unfortunately, many of us work in places where IT is viewed as a cost or just a means to an end. In these shops, too often, HR and development staff may work against each other due to differences in opinion as to what a good developer is or what one is worth.  It seems that if you ask two different people what makes a good developer, often you will get three different opinions.   With the exception of those shops that are purely development-centric (you guys have it much easier!), most other shops have management who have very little knowledge about the development process.  Their view can often be that development is simply a skill that one learns and then once aquired, that developer can produce widgets as good as the next like workers on an assembly-line floor.  On the other side, you have many developers that feel that software development is an art unto itself and that the ability to create the most pure design or know the most obscure of keywords or write the shortest-possible obfuscated piece of code is a good coder.  So is it a skill?  An Art?  Or something entirely in between?   Saying that software is merely a skill and one just needs to learn the syntax and tools would be akin to saying anyone who knows English and can use Word can write a 300 page book that is accurate, meaningful, and stays true to the point.  This just isn't so.  It takes more than mere skill to take words and form a sentence, join those sentences into paragraphs, and those paragraphs into a document.  I've interviewed candidates who could answer obscure syntax and keyword questions and once they were hired could not code effectively at all.  So development must be more than a skill.   But on the other end, we have art.  Is development an art?  Is our end result to produce art?  I can marvel at a piece of code -- see it as concise and beautiful -- and yet that code most perform some stated function with accuracy and efficiency and maintainability.  None of these three things have anything to do with art, per se.  Art is beauty for its own sake and is a wonderful thing.  But if you apply that same though to development it just doesn't hold.  I've had developers tell me that all that matters is the end result and how you code it is entirely part of the art and I couldn't disagree more.  Yes, the end result, the accuracy, is the prime criteria to be met.  But if code is not maintainable and efficient, it would be just as useless as a beautiful car that breaks down once a week or that gets 2 miles to the gallon.  Yes, it may work in that it moves you from point A to point B and is pretty as hell, but if it can't be maintained or is not efficient, it's not a good solution.  So development must be something less than art.   In the end, I think I feel like development is a matter of craftsmanship.  We use our tools and we use our skills and set about to construct something that satisfies a purpose and yet is also elegant and efficient.  There is skill involved, and there is an art, but really it boils down to being able to craft code.  Crafting code is far more than writing code.  Anyone can write code if they know the syntax, but so few people can actually craft code that solves a purpose and craft it well.  So this is what I want to find, I want to find code craftsman!  But how?   I used to ask coding-trivia questions a long time ago and many people still fall back on this.  The thought is that if you ask the candidate some piece of coding trivia and they know the answer it must follow that they can craft good code.  For example:   What C++ keyword can be applied to a class/struct field to allow it to be changed even from a const-instance of that class/struct?  (answer: mutable)   So what do we prove if a candidate can answer this?  Only that they know what mutable means.  One would hope that this would infer that they'd know how to use it, and more importantly when and if it should ever be used!  But it rarely does!  The problem with triva questions is that you will either: Approve a really good developer who knows what some obscure keyword is (good) Reject a really good developer who never needed to use that keyword or is too inexperienced to know how to use it (bad) Approve a really bad developer who googled "C++ Interview Questions" and studied like hell but can't craft (very bad) Many HR departments love these kind of tests because they are short and easy to defend if a legal issue arrises on hiring decisions.  After all it's easy to say a person wasn't hired because they scored 30 out of 100 on some trivia test.  But unfortunately, you've eliminated a large part of your potential developer pool and possibly hired a few duds.  There are times I've hired candidates who knew every trivia question I could throw out them and couldn't craft.  And then there are times I've interviewed candidates who failed all my trivia but who I took a chance on who were my best finds ever.    So if not trivia, then what?  Brain teasers?  The thought is, these type of questions measure the thinking power of a candidate.  The problem is, once again, you will either: Approve a good candidate who has never heard the problem and can solve it (good) Reject a good candidate who just happens not to see the "catch" because they're nervous or it may be really obscure (bad) Approve a candidate who has studied enough interview brain teasers (once again, you can google em) to recognize the "catch" or knows the answer already (bad). Once again, you're eliminating good candidates and possibly accepting bad candidates.  In these cases, I think testing someone with brain teasers only tests their ability to answer brain teasers, not the ability to craft code. So how do we measure someone's ability to craft code?  Here's a novel idea: have them code!  Give them a computer and a compiler, or a whiteboard and a pen, or paper and pencil and have them construct a piece of code.  It just makes sense that if we're going to hire someone to code we should actually watch them code.  When they're done, we can judge them on several criteria: Correctness - does the candidate's solution accurately solve the problem proposed? Accuracy - is the candidate's solution reasonably syntactically correct? Efficiency - did the candidate write or use the more efficient data structures or algorithms for the job? Maintainability - was the candidate's code free of obfuscation and clever tricks that diminish readability? Persona - are they eager and willing or aloof and egotistical?  Will they work well within your team? It may sound simple, or it may sound crazy, but when I'm looking to hire a developer, I want to see them actually develop well-crafted code.

• How do you fix "failed command: IDENTIFY DEVICE" showing up in dmesg?

  - by Neil

  I just got a new Mushkin 60gb SSD, and it's now my primary drive in the ata1 spot. I've been getting these failed command: IDENTIFY DEVICE errors which are preventing rebooting and shutdown. Does anyone know what these could be caused by, or how to start troubleshooting? I've tried these kernels: 2.6.32-22-generic 2.6.31-17-generic And they both have the same error. Here is a link to my entire dmesg. And the relevant ata1.00 parts below: [ 59.804237] ata1: drained 256 bytes to clear DRQ.

• adding hard drive failed

  - by dennis ditch

  i was using von welch's instructions at http://v2kblog.blogspot.com/2007/05/adding-second-hard-drive.html] to install a 500 gig seagate drive to write the recordings to. everything seemed to be going ok until mkfs /dev/sdb1 then we get an error message mkfs.ext2: inode_size (128) * inodes_count (0) too big for a filesystem with 0 blocks, specify a higher inode_ratio (-i) or lower inode count (-N) my son is trying to help me but this is beyond him. our knowledge of unix/linux is very limited. at work the support people just sent me a line by line cook book. i would appreciate any help you can give us. the computer is a gateway mdp e4000 . mythbuntu is installed on a pata drive and we are adding a sata drive for the second drive. the bios sees the drive.
