  • Good and easy way to share files on local machine

    - by jb
    I would like to have a directory that has following properties: Many users can copy files into it These files can be deleted/changed by these users (user A can delete/modify file that was copied into this directory) it cant be done using normal file permissions (because permissions are retained on copy). Here is what I found on the net: brainstorm idea blueprint Some use cases: Sharing music on local machine Simple git repository sharing (just make a bare repository writeable to many people) --- i know that there are solutions like gitosis Allow many developers to modify test instance of php app without giving them root (i guess they would copy files) --- I'm leading a team of nonprofit junior developers and I need to keep that one simple! EDIT AFAIK setting SGID bit is not enugh, it only affects newly created files --- and basic workflow for these use cases ivnolves copying and other operations (which cleave file's gid unchanged)

  • Live boot from hard disk problem

    - by user172277
    I've installed Ubuntu Desktop 13.04 32bit. Next I configured /etc/grub.d/40_custom to boot live system from ubuntu.iso (also Desktop 13.04 32 bit) I used configuration: menuentry "Ubuntu 13.04 Desktop" { loopback loop /boot/ubuntu.iso linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=/boot/ubuntu.iso noeject noprompt splash -- initrd (loop)/casper/initrd.lz } and it works OK. Later I made some changes on my installed ubuntu. I made some configuration, installed additional packages and so on. After that I made backup using remastersys tool. Remastersys gave me new ISO file. So I wanted to use it. And here was first problem. Remastersys creates only initrd.gz file. So I changed the grub configuration form: initrd (loop)/casper/initrd.lz to: initrd (loop)/casper/initrd.gz But after that, when I reboot my system I get error: /init: line 3: can't open /dev/sr0: No medium found Any ideas how to fix it? Best Regards, Bartosz

  • Recovery from URL structure change?

    - by Dejan Pelzel
    in July this year, we have changed the URL structure of the website from: Post: domain.com/blog/post/986/dance/heart-beats-dance-video-by-chinatsu/ Category: domain.com/blog/index/cosplay/ to Post: domain.com/dance/heart-beats-dance-video-by-chinatsu-986/ Category: domain.com/cosplay/ Everything was (supposedly) properly redirected with 301 redirects and it first seemed that the traffic returned after a couple of days, but it has now been close to 2 months and things keep going worse although Google is slowly indexing the changes. What is worrying me even more is that the Pages crawled per day from Webmaster Tools started drastically dropping a few days ago and has just reached a new low in months (from over 2000 to 700). Should I be worried or will things sort out eventually?

  • Difference in fans on Windows 7 and Ubuntu 12.04

    - by Timo
    I have bought a Hp Pavilion DV7 with Core i7 CPU and installed Ubuntu 12.04 on dual boot with Windows 7 alongside. Apart from the difference in battery life (although that's fixed with Jupiter), I have another problem with the fans. On Windows my fans work perfectly and the laptop is cool, but it seems to overheat in Ubuntu. It becomes quite hot and it looks like my fans are not working under Ubuntu. I think I'm having the same problem as How can I keep the cpu temp low?, but since I cannot comment because of the lack of reputation (?), I post the question as a new thread. I think the result of the overheating is that my keyboard doesn't seem to follow when I start typing a long text. It just freezes and types the last letter multiple times. For example: when I type the word freezes, it shows freeeee so the zes changed into eee...

  • Should I update blog posts or rewrite them as technology (and me) changes?

    - by Rachel
    I started a programming blog earlier this year, and since I started it some things have changed. Some changes are due to technology changing, some changes are due to my code libraries improving, and some (ok, probably most) are due to me changing as I learn more. I want to go back and completely re-write certain blog posts. Is it better to rewrite posts to remove old information and update them with new stuff, or to create entirely new posts and possibly take down old ones? I'm not talking about small changes to the code, or an extra few sentences, but complete rewrites with new code, new information, etc. Some things to consider are comments on the post, subscribers who receive updates when new posts are created, and user bookmarks.

  • Accidentally Uninstalled Ubuntu Desktop and Anacron. Reinstalled. What Can I Expect?

    - by Volomike
    Unfortunately when I installed the cron package to take a look at it, I didn't realize that I was also uninstalling Ubuntu Desktop and Anacron. Crap!!! So, I then did apt-get install anacron ubuntu-desktop, which also removed fcron. However, I need to know what instability issues I may now encounter because I have done this change and changed it back. I mean, now that anacron is back and ubuntu-desktop is back, am I out of the woods? Or, will I lose any important jobs that need to run periodically from anacron?

  • library put in /usr/local/lib is not loaded

    - by IARI
    Let me state in advance: One might think this question would is for server fault, but I think is is Ubuntu (config) specific. In short: I have put libwkhtmltox.so in /usr/local/lib as stated in installation instructions linked below, but it appears the library is not loaded. I am trying to install php-wkhtmltox, a php extension for wkhtmltox on my local desktop (Ubuntu 12.04). I have extracted the source and changed to the corresponding directory. After running phpize, ./configure fails at checking for libwkhtmltox support... yes, shared not found configure: error: Please install libwkhtmltox I suspect the reason the library is not loaded is that the path is not checked!? how do I proceed? Here are instructions I followed: http://davidbomba.com/index.php/2011/08/04/php-wkhtmltox/ http://roundhere.net/journal/install-wkhtmltopdf-php-bindings/

  • Working as an entry .Net Developer in the USA [closed]

    - by Abdullah
    I just have a question about .net entry level jobs in VA. I am a master degree student in field of software engineering but I am graduated from department of physics. I decided to work on Java first, but I have changed my mind because I don't have any Java programming background except Java class in master degree so I decided to work on C# because it was easy to me to work with Visual Studio and it's fun to me to work with SQL database and HTML stuffs. And I am a member of a IT consultant company in Reston where I took course from there about .net and I created online recruitment system for their web site. Now I am applying for CPT (internship) but I didn't work in a company as a .net developer so I don't have experience. Here is my question. If I get CPT and find a job, what do software companies want from an entry level .net developer? and what do they ask as interview questions?

  • Remapping Shift Selection in Gnome Terminal

    - by Gowie47
    Hey so I was hoping somebody could help me out in finding a way to get shift-selection working in gnome-terminal on Ubuntu 11.10. I found the question/bug report below but neither seem to have a solution. I use Emacs for development and being able to select my current line with shift-ctrl-a/e is something I find myself trying to do every couple of minutes. I use 10.04 at work and this is possible so I am not sure what has changed. If it matters I am using Gnome 3 Shell and I use bashish to style my terminal. Thanks in advance! https://bugs.launchpad.net/ubuntu/+source/vte/+bug/546021 http://askubuntu.com/questions/31991/using-the-shift-key-in-terminal

  • Facebook link to facebook.com/company-page doesn't work

    - by Teo
    For the last 2 days I'm trying to find the reason why my previous setup, which was a link to my websites Facebook pages doesn't work anymore. I assume that I mistakenly changed something in the Facebook developer area, but I can't remember what it was. The bottom linked my previously to the Facebook.com/company-page, now the same Bottom links me just to Facebook.com. I guess I saw some redirect in the tab, but I'm not sure since it's too fast changing to Facebook.com. The original link in the footer is correct : <a href="http://facebook.com/company-page " target="_blank" class="facebook_ico"></a>. Any ideas?

  • Ubuntu sudo not working

    - by Ron Sebastian
    I wanted to move a file to a /usr/python2.7/ but i was unable to do so, so i changed the permissions of /usr to myuser: sudo chown -R ***** /usr it worked but i realised it was a blunder when sudo stopped working after that. It says: sudo: effective uid is not 0, is sudo installed setuid root? I have seen this post where the accepted solution was to use the policykit: pkexec chown root:root /usr/bin/sudo pkexec chmod 4755 /usr/bin/sudo however, even the policykit is saying that: pkexec must be setuid root please help, i've learned a lesson and will never change permissions for /usr again. Please help me this time!

  • How to Export Email "Sent" Folder?

    - by user249493
    A client had her web site and email hosted at "company A". She was switching to "company B" but didn't want to lose her email. I set up a Gmail account, POPed into her webmail account, and pulled the entire inbox into Gmail (for later transfer to her new host). But I forgot about the "sent" folder. Although the hosting plan is still up and running, she changed her domain record to point to the new host. So I can't access the old webmail account via POP or IMAP because the email address needed for authentication now resolves to the new host. Is there any way I can get the contents of the sent folder without having to do a "forward" one message at a time (there are hundreds)?

  • Settings xorg.conf to be used with VESA driver?

    - by Fernando Costa
    I have an brand new installation of Ubuntu 9.10 (karmic version) where everything is fine except the video resolution. In Ubuntu 9.10, the file xorg.conf is empty by default. I'm using an onboard video card, and Ubuntu can not find the right resolution for me. It always uses 800x600, but I need at least 1024x768. Also, my monitor is listed as Unknown Type. Ubuntu did find the right resolution when I changed the monitor to a Samsung monitor. By the way what are the generic settings to put inside xorg.conf? What is the settings for Refresh Rate, for example, I got a resolution of 1280x800, but the Refresh Rate generally between 60 ~ 80 htz is ZERO on my resolution.. In 1024 resolution my Refresh Rate is 75 htz.. What is going on with my resolution and how to modify the Refresh Rate?? Many Thanks!

  • How much is modern programming still tied to underyling digital logic?

    - by New Talk
    First of all: I've got no academic background. I'm working primarily with Java and Spring and I'm also fond of web programming and relational databases. I hope I'm using the right terms and I hope that this vague question makes some sense. Today the following question came to my mind: How much is modern programming still tied to the underlying digital logic? With modern programming I mean concepts like OOP, AOP, Java 7, AJAX, … I hope you get the idea. Do they no longer need the digital logic with which computers are working internally? Or is binary logic still ubiquitous when programming this way? If I'd change the inner workings of a computer overnight, would it matter, because my programming techniques are already that abstract? P. S.: With digital logic I mean the physical representation of everything "inside" the computer as zeroes and ones. Changed "binary" to "digital".

  • Why do my Google sitelinks show gibberish for a PDF link?

    - by Tom
    I have a website which Google lists nicely along with site links. One of the site links - to a PDF file - shows un-human gibberish e.g 67,8;45:: 56 83 @7<1. (7/0;,*;: /59( (7/0;,;<7, <7)(60:4 (9<7 /+ +2, VU I thought it might be due to the PDF's title property so I changed it. But there hasn't been an improvement to the site link. Other PDF site links are fine and display the title property as desired. Does anyone know how I might rectify this problem or what might be the cause? My uninformed guess is it's some transliteration problem between code and display text which, I suppose, means I ought to recondition the PDF file in some way. Not sure how.

  • Secure Deployment of Oracle VM Server for SPARC - updated

    - by Stefan Hinker
    Quite a while ago, I published a paper with recommendations for a secure deployment of LDoms.  Many things happend in the mean time, and an update to that paper was due.  Besides some minor spelling corrections, many obsolete or changed links were updated.  However, the main reason for the update was the introduction of a second usage model for LDoms.  In a very short few words: With the success especially of the T4-4, many deployments make use of the hardware partitioning capabilities of that platform, assigning full PCIe root complexes to domains, mimicking dynamic system domains if you will.  This different way of using the hypervisor needed to be addressed in the paper.  You can find the updated version here: Secure Deployment of Oracle VM Server for SPARCSecond Edition I hope it'll be useful!

  • Detail of acceptance criteria in user story

    - by Kai Kramhoeft
    I have the following example for a user story with acceptance criteria. I would like to know if I am allowed to describe how the GUI must be changed to support the new feature. How much detail can acceptance criteria have? This is my example: User Story: As forum administrator I will connect persons in groups, so that people can get organized. Acceptance Criteria: The creation of a person group happens below a person group pool (person group pool is an object also visually available in the current software system) The creation happens with a context menu of the persongroup pool. Below the pool one can create new groups. A person group contains: person group-ID, description, remark May that be relevant an right acceptance criteria? Because I describe how you can create a new group by opening a context menu.

  • How to prevent creation of monitors.xml?

    - by user222723
    I'm using Ubuntu on a tablet and have a problem with the screen rotation, which I can fix by removing ~/.config/monitors.xml, but sadly every time I rotate the screen a new monitors.xml is created. Is there any way to prevent this? I already tried to create an empty file with the same name as root but it was still overwritten after rotating the screen. Edit: I think I finally found the reason for the problem. Everytime the orientation is changed the new orientation is saved in monitors.xml while the original monitors.xml is saved as monitors.xml.backup. By playing around with chattr I found out that this causes Ubuntu to try to restore monitors.xml out of monitors.xml.backup after every login. So if I turn the screen to the left and then back to normal monitors.xml says "orientation=normal" and monitors.xml.backup says "orientation=left". After the login Ubuntu overwrites monitors.xml with the backup and uses its configuration and turns the screen to the left.

  • How to credit other authors in an open source project

    - by erik
    I have a pet project that I am planning to release as open source at some point in the not-too-distant future. A couple of the files use or are mostly code that was taken from a project released under the New BSD License. While I have changed it to fit my needs and added some small stuff, the algorithm and the functionality is basically exactly the same. I want to make sure that the author of the code gets credit and that the license is not broken, but I also want to make the reader aware that this is not the code as it was orignally released. How should I approach this? Should I isolate the code as much as possible and just retain the original license? Maybe put all the files that contain foreign code in their own folder and add a readme explaining what has been added/removed? There must have been tons of projects using other open source code. What is the standard approach to this?

  • Why did Git become so popular?

    - by Jungle Hunter
    Almost every article you read comparing Git and Mercurial it seems like Mercurial has a better command line UX with each command being limited to one idea only (unlike say git checkout). But at some point Git suddenly became super popular and literally exploded. Source: Debian What happened in 2010-01 that things suddenly changed. Looks like GitHub was founded earlier than that - 2008. Edit: Git 1.7.0 seems to be released at the same time: January 2012. Here are the 1.7.0 release notes and the file history with the corresponding dates.

  • Avoiding That Null Reference!

    - by TheJuice
    A coworker had this conversation with another of our developers. Names have been changed to protect the guilty. Clueless: hey! Clueless: I am using the ?? operator for null check below Nice Guy: hey Clueless: FundLoanRequestBoatCollateral boatCollateral = request.BoatCollateral ?? null; Nice Guy: that's not exactly how it works Clueless: I want to achive: FundLoanRequestBoatCollateral boatCollateral = request.BoatCollateral != null ? request.BoatCollateral : null; Clueless: isnt that equal to:  FundLoanRequestBoatCollateral boatCollateral = request.BoatCollateral ?? null; Nice Guy: that is functionally equivalent to FundLoanRequestBoatCollateral boatCollateral = request.BoatCollateral Nice Guy: you're checking if it's null and if so setting it to null Clueless: yeah Clueless: if its null I want to set it to null Nice Guy: if it's null then you're already going to set it to null, no special logic needed Clueless: I wanted to avoid a null reference if BoatCollateral is null   The sad part of all of this is that "Clueless" has been with our company for years and has a Master's in Computer Science.
