• Unable to boot ubuntu 11.10 from external usb drive

  - by user45006

  I'm new to Ubuntu (and actually all things Linux) as of this morning, so please excuse any stupid mistakes I may be making. I recently bought an external hard drive for my newly built PC (that is running windows 7 if it matters). I would like to install Ubuntu onto the external drive and boot from there. I downloaded Ubuntu 11.10 and made a bootable cd, unplugged my internal HDDs, plugged in the external drive, installed Ubuntu 11.10 on the external drive via the installer, and replugged in my internal HDDs. Then I set my bios boot order to: Boot from USB-HDD - Boot from Hard Disk - Boot from CD/DVD. Now when I restart I get the message "Starting Operating System..." (or something like that, I forget exactly what it says) that lingers on the screen for a moment and then windows starts. Any idea what the problem may be? ~Relevant info~ BIOS version: Award Software International, Inc. F2, 2/22/2011 Ubuntu Version: 11.10 External Hard Drive: Western Digital My Passport Essential 500GB Portable Hard Drive (Black) ~Things I've already tried~ 1) Unplug internal HDDs so that only external drive was plugged in via usb. Same thing happened only obviously my BIOS could not detect any hard drives besides the external one. When booting received error "Could not detect operating system" 2) Formatted external hard drive and re installed. It didn't make a difference, however interestingly when I booted from cd the ubuntu installer said it detected ubuntu 11.10 on the external hard drive. 3) Within BIOS I've messed around with every boot order combo I could think of both in the "Hard Disk boot order" screen and the "Boot order" screen. I'm a little confused of why there are two screens for this. 4) Held F12 during startup which opens (what I think is) the one time boot screen and it gave me the options "Hard Drive", "cd/dvd", "USB-FDD", "USB-cdrom", "USB-HDD", and "USB-something else I can't remember what it was". I tried all of them, but the same thing as before happened each time. ~References~ I noticed several people on askubuntu have tried to do something similar if not the exact same. In fact, I even found a post that pretty much outlines step by step exactly what I did... only their's worked. /jealous. Linky: Install Ubuntu or Kubuntu on a External USB Drive I'm willing to try a different version of ubuntu - it's not like my heart is set on 11.10, but it's a pain to open my case and unplug my internal hard drives so I'd prefer not to do this unless someone is reasonably confident it'll work. Thank you for all of your help in advance! I'm really looking forward to exploring Ubuntu!

• How do I take responsibility for my code when colleague makes unnecessary improvements without notice?

  - by Jesslyn

  One of my teammates is a jack of all trades in our IT shop and I respect his insight. However, sometimes he reviews my code (he's second in command to our team leader, so that's expected) without a heads up. So sometimes he reviews my changes before they complete the end goal and makes changes right away... and has even broken my work once. Other times, he has made unnecessary improvements to some of my code that is 3+ months old. This annoys me for a few reasons: I am not always given a chance to fix my mistakes He has not taken the time to ask me what I was trying to accomplish when he is confused, which could affect his testing or changes I don't always think his code is readable Deadlines are not an issue and his current workload doesn't require any work in my projects other than reviewing my code changes. Anyways, I have told him in the past to please keep me posted if he sees something in my work that he wants to change so that I could take ownership of my code (maybe I should have said "shortcomings") and he's not been responsive. I fear that I may come off as aggressive when I ask him to explain his changes to me. He's just a quiet person who keeps to himself, but his actions continue. I don't want to banish him from making code changes (not like I could), because we are a team--but I want to do my part to help our team. Added clarifications: We share 1 development branch. I do not wait until all my changes complete a single task because I risk losing some significant work--so I make sure my changes build and do not break anything. My concern is that my teammate doesn't explain the reason or purpose behind his changes. I don't think he should need my blessing, but if we disagree on an approach I thought it would be best to discuss the pros and cons and make a decision once we both understand what is going on. I have not discussed this with our team lead yet as I would prefer to resolve personal disagreements without getting management involved unless it is necessary. Since my concern seemed more of personal issue than a threat to our work, I chose to not bother the team lead. I am working on code review process ideas--to help promote the benefits of more organized code reviews without making it all about my pet peeves.

• Collision in PyGame for spinning rectangular object.touching circles

  - by OverAchiever

  I'm creating a variation of Pong. One of the differences is that I use a rectangular structure as the object which is being bounced around, and I use circles as paddles. So far, all the collision handling I've worked with was using simple math (I wasn't using the collision "feature" in PyGame). The game is contained within a 2-dimensional continuous space. The idea is that the rectangular structure will spin at different speed depending on how far from the center you touch it with the circle. Also, any extremity of the rectangular structure should be able to touch any extremity of the circle. So I need to keep track of where it has been touched on both the circle and the rectangle to figure out the direction it will be bounced to. I intend to have basically 8 possible directions (Up, down, left, right and the half points between each one of those). I can work out the calculation of how the objected will be dislocated once I get the direction it will be dislocated to based on where it has been touch. I also need to keep track of where it has been touched to decide if the rectangular structure will spin clockwise or counter-clockwise after it collided. Before I started coding, I read the resources available at the PyGame website on the collision class they have (And its respective functions). I tried to work out the logic of what I was trying to achieve based on those resources and how the game will function. The only thing I could figure out that I could do was to make each one of these objects as a group of rectangular objects, and depending on which rectangle was touched the other would behave accordingly and give the illusion it is a single object. However, not only I don't know if this will work, but I also don't know if it is gonna look convincing based on how PyGame redraws the objects. Is there a way I can use PyGame to handle these collision detections by still having a single object? Can I figure out the point of collision on both objects using functions within PyGame precisely enough to achieve what I'm looking for? P.s: I hope the question was specific and clear enough. I apologize if there were any grammar mistakes, English is not my native language.

• How bad does it look to have left a job soon after starting? [closed]

  - by unitedgremlin

  I have a job I would like to leave. On advice from friends and parents I have stayed. Their primary concern is that it would look bad on my resume if I left only after a few months of joining. My concerns with the job are as follows: When I started it was preferred I provide and use my own equipment. Could be out of business in a few months from lack of cash flow Poor code quality: memory leaks and lack of error handling. The same mistakes continue to be made even though I have raised the issue. It has become evident that co-workers do not understand memory management rules of the platform and are not interested in learning them. Yet, there is still surprise from them when strange bugs continue to crop up. As a result don't feel I will learn from co-workers. Plus, fixing the the lingering bugs and trying to keep up on new feature development is like a game of whack-o-mole that never ends. I don't believe in the companies vision or its ability to execute on the ideas anymore. My ideas and suggestions for very small tweaks are quickly dismissed. And so more than half or so have come back as bugs that we end up needing to address. I have been told to wait on fixing bugs in codes until we can talk to the original author. I don't feel I am allowed to take initiative to just fix/change things and do what I think is best. Everything needs consensus even for a bug fix before any work is done. I am adopting a shut-up and just do what I am told approach to save myself from ulcers. Lots of meetings (I am personally not involved in all of them which is good) but the sheer amount reminds me of days at a big corporation. Why is everyone around me always meeting? It's a small company. I can count everyone on my toes and fingers. I can say with certainty I have no interest in working with any of them again. This is the first time I have truly worked with a group of so called "B and C players". Ultimately, I think it is my fault for not doing a better job evaluating the team and company before joining. But I have generated a better set of questions when probing companies in the future. My questions are: How bad does it look to have left a job soon (few months) after starting? What would be the best way to explain my concerns and reasons for leaving without badmouthing the company? Should I stick it out to what I believe will be the soon end of the company?

• Is it unusual for a small company (15 developers) not to use managed source/version control?

  - by LordScree

  It's not really a technical question, but there are several other questions here about source control and best practice. The company I work for (which will remain anonymous) uses a network share to host its source code and released code. It's the responsibility of the developer or manager to manually move source code to the correct folder depending on whether it's been released and what version it is and stuff. We have various spreadsheets dotted around where we record file names and versions and what's changed, and some teams also put details of different versions at the top of each file. Each team (2-3 teams) seems to do this differently within the company. As you can imagine, it's an organised mess - organised, because the "right people" know where their stuff is, but a mess because it's all different and it relies on people remembering what to do at any one time. One good thing is that everything is backed up on a nightly basis and kept indefinitely, so if mistakes are made, snapshots can be recovered. I've been trying to push for some kind of managed source control for a while, but I can't seem to get enough support for it within the company. My main arguments are: We're currently vulnerable; at any point someone could forget to do one of the many release actions we have to do, which could mean whole versions are not stored correctly. It could take hours or even days to piece a version back together if necessary We're developing new features along with bug fixes, and often have to delay the release of one or the other because some work has not been completed yet. We also have to force customers to take versions that include new features even if they just want a bug fix, because there's only really one version we're all working on We're experiencing problems with Visual Studio because multiple developers are using the same projects at the same time (not the same files, but it's still causing problems) There are only 15 developers, but we all do stuff differently; wouldn't it be better to have a standard company-wide approach we all have to follow? My questions are: Is it normal for a group of this size not to have source control? I have so far been given only vague reasons for not having source control - what reasons would you suggest could be valid for not implementing source control, given the information above? Are there any more reasons for source control that I could add to my arsenal? I'm asking mainly to get a feel for why I have had so much resistance, so please answer honestly. I'll give the answer to the person I believe has taken the most balanced approach and has answered all three questions. Thanks in advance

• Is there any alternative to TeamViewer VPN? [closed]

  - by Dzmitry Lahoda

  TeamViewer VPN connection mode lets you create a virtual private network (VPN) between two TeamViewer computers. Two computers connected via VPN act as in a common network. This allows you to access the resources of your partner's computer and vice versa. What other programs can do the same thing? EDIT I made VPN connection using TeamViewer. But Test ping button opens console where I just see "destination host is unreachable" or "request timed out".

• How do I configure AT&T's Uverse 2Wire 2701HGV-B Gateway into DMZPlus Mode?

  - by MasD

  I subscribed for AT&T's Uverse service and they shipped me a Wire 2701HGV-B Router/Gateway/Firewall/WiFi. I would like to configure AT&T's hardware to have less control and use my trusted Linksys WRT54-G router between my computers and the 2Wire Gateway. This seems to be a common configuration for Uverse users with this hardware in other forums, but requires a "DMZPlus" mode that I'm unfamiliar with.

• FTP Error: 550 Cant change directory to /: Permission denied

  - by Alessandro Merletti de Palo

  I installed Pureftpd and Ispconfig3 on my server. Starting from the point I'll probably uninstall ispconfig3 and make things directly on the server, now I am so stubborn I really want to see where's the problem. I created a ftp user through ispconfig, named amdpftp. It is related to a server user named web7. It logs in with username and password, but if i try to ls, it tells me: FTP Error: 550 Cant change directory to /: Permission denied I thought many things, like: 1. It is a problem of permissions. I went to /var/www/clients/client0/web7 , it was immutable and owned by root. Chattr -i and chown web7:client0 changed permissions, but with no effect. I restored to root:root, and made it immutable again. 2. I make some mistakes in the pureftpd installation: Wrong, it works pretty fine. The pureftpd.log doesn't seem to say anything bad. 3. The pureftpd.log file is only the pureftpd one, I should also check the mysqld functionality, as it is in a mysql database that user, password and working directory are stored. I enabled logging in the my.cnf, but also in the ispconfig database operation there wasn't anything wrong. Then I mkdir testftp in /var/www, chown web7:client0, and edited amdpftp user root directory from /var/www/clients/client0/web7 into /var/www/testftp . Guess what? It worked. So, now I know: 1. The PureFtpd works pretty fine 2. The mysql ispconfig database as well 3. The username and password of the virtual user created by ispconfig into pureftpd work 4. The correlation between username and password and the user web7 and the group client0 does work. What kind of magic has been cast upon the ispconfig directories [/var/www/clients/*] that block ftpusers to operate?

  I installed Linux Mint 12 on my Dell Studio 15 and everything worked perfectly up until I tried updating the STA Driver for the Broadcom (BCM4312) wireless controller. I've tried these bash commands in order and I still don't have wireless. sudo apt-get install b43-fwcutter sudo apt-get install b43-fwcutter firmware-b43-installer I've also tried uninstalling everything with synaptic package manager including broadcom-sta-common and broadcom-sta-source, then restarting and running the above commands which didn't work either. What's the best way to do this on a Dell Studio 15?

• openvpn: after changing to server mode, client does not create TUN device

  - by lurscher

  i had a previously working configuration with the config files used in a previous question However, i've changed this now to the following configuration using server mode, everything on the logs seem fine, however the client doesn't create any tun interface, so i don't have anything to connect to, presumably, i need to add or push some route commands, but i don't have any idea at this point what i need to do.

  I created a custom syntax file, and but none of the files in $VIMRUNTIME seem to load.

• Website for facilitating interactive discussion ?

  - by shan23

  I had heard of websites that would allow two or more people to share a common text editor, so that changes to the text can be made and simultaneously viewed by all participants in real time - this kind of websites is ostensibly used for conducting interviews online. I know they exist (I had read of them in a tech magazine), but I can't seem to find the right search term for google to throw me a correct link. So, I'm asking you guys, as you might have used it before, or know what I'm talking about.

• Bidirectional real-time sync of large file tree between two distant linux servers

  By large file tree I mean about 200k files, and growing all the time. A relatively small number of files are being changed in any given hour though. By bidirectional I mean that changes may occur on either server and need to be pushed to the other, so rsync doesn't seem appropriate. By distant I mean that the servers are both in data centers, but geographically remote from each other. Currently there are only 2 servers, but that may expand over time. By real-time, it's ok for there to be a little latency between syncing, but running a cron every 1-2 minutes doesn't seem right, since a very small fraction of files may change in any given hour, let alone minute. EDIT: This is running on VPS's so I might be limited on the kinds of kernel-level stuff I can do. Also, the VPS's are not resource-rich, so I'd shy away from solutions that require lots of ram (like Gluster?). What's the best / most "accepted" approach to get this done? This seems like it would be a common need, but I haven't been able to find a generally accepted approach yet, which was surprising. (I'm seeking the safety of the masses. :) I've come across lsyncd to trigger a sync at the filesystem change level. That seems clever though not super common, and I'm a bit confused by the various lsyncd approaches. There's just using lsyncd with rsync, but it seems this could be fragile for bidirectionality since rsync doesn't have a notion of memory (eg- to know whether a deleted file on A should be deleted on B or whether it's a new file on B that should be copied to A). lipsync appears to be just a lsyncd+rsync implementation, right? Then there's using lsyncd with csync2, like this: http://www.axivo.com/community/threads/lightning-fast-synchronization-with-csync2-and-lsyncd.121/ ... I'm leaning towards this approach, but csync2 is a little quirky, though I did do a successful test of it. I'm mostly concerned that I haven't been able to find a lot of community confirmation of this method. People on here seem to like Unison a lot, but it seems that it is no longer under active development and it's not clear that it has an automatic trigger like lsyncd. I've seen Gluster mentioned, but maybe overkill for what I need? UPDATE: fyi- I ended up going with the original solution I mentioned: lsyncd+csync2. It seems to work quite well, and I like the architectural approach of having the servers be very loosely joined, so that each server can operate indefinitely on its own regardless of the link quality between them.

• Electronics Recycling

  - by Evan Carroll

  Is it common practice to not pay for recycling electronics? I find it kind of funny that scrap metal demands such a premium but electronics recycling gets nothing. My dad owns a stereostore and throws away hundreds of radio head-units a month is there anything useful or profitable that can be done with electronics on such a mass scale? http://stselectronicrecyclinginc.com/index.php/electronics-recycling http://www.basscomputerrecycling.com/?page_id=30 http://www.computerrecyclecenter.com/services.htm None of them seem to pay anything for the scrap.

• IIS 7 Cannot Access Website

  - by UberError

  We can access our website from other systems, but when logged into the local machine where the site is hosted it does not resolve to the site... for example: http://mysite.com/folder/page.aspx gets a 404.... from the local machine we also cannot ping mysite.com ... What are some common things to check to troubleshoot this issue? I'm new to IIS 7 so sorry for the vague question.

• Trac problem: AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule"

  - by Janosch

  This problem already has been described mutliple times in different mailing lists, but no solution has yet been published. My original setup is as follows (but in the mean time i have a simpler one on Windows 7): Ubuntu server with apache 2.2 and python 2.7 virutal python environment created with virtualenv installed babel, genshi and trac in this order using pip in the virtual environment Trac seems to run fine with tracd, but when visiting it through apache, i get the following error in an official trac error page: AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule" The stacktrace looks like this: Traceback (most recent call last): File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/web/main.py",line 473, in _dispatch_request dispatcher.dispatch(req) File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/web/main.py", line 154, in dispatch chosen_handler = self.default_handler File "/srv/trac/python-environment/lib/python2.5/site-packages/Trac-0.13dev_r10668-py2.5.egg/trac/config.py", line 691, in __get__ self.section, self.name)) AttributeError: Cannot find an implementation of the "IRequestHandler" interface named "WikiModule". Please update the option trac.default_handler in trac.ini. I already tried a lot to get down to the root of the problem, for me it looks as if all nativ trac components refuse to load. When one explicitely imports these components in the wsgi handler, some of them start to work somehow. Since i suspected the virtual environment, i dropped it, and manually copied all dependencies (babel, genshi, trac, ..) to one directory, and added this directory to system.path in the wsgi handler. I get exactly the same error. Since this setup is now independend from the environment, one can easily try it out on any other machine (windows or linux) running apache 2 and python 2.7. On my Windwos 7 machine, i got exactly the same problem. I zipped together the whole bundle, one can download it from http://www.xterity.de/tmp/trac-installation.zip . In the apache configuration (Windows 7 machine) i use the following settings: Alias /trac/chrome/common "D:/workspace/trac-installation/trac-resources/common" Alias /trac/chrome/site "D:/workspace/trac-installation/trac-resources/site" WSGIScriptAlias /trac "D:/workspace/trac-installation/apache/handler.wsgi" <Directory "D:/workspace/trac-installation/trac-resources"> Order allow,deny Allow from all </Directory> <Directory "D:/workspace/trac-installation"> Order allow,deny Allow from all </Directory> <Location "/trac"> Order allow,deny Allow from all </Location> And my handler.wsgi looks like this: import os import sys sys.path.append('D:/workspace/trac-installation/dependencies/') os.environ['TRAC_ENV'] = 'D:/workspace/trac-installation/trac-environments/Esp004' os.environ['PYTHON_EGG_CACHE'] = 'D:/workspace/trac-installation/eggs' import trac.web.main application = trac.web.main.dispatch_request Has anybody got an idea what could be the problem, or how to find out where it comes from?

• Why Does Wireless Gear Degrade Over Time?

  - by bahamat

  I saw this originally posted on slashdot, but their comment format is not conducive to actually getting a correct answer. Having directly experienced this phenomenon myself, I'm now asking here where I think I can actually get an educated answer. Here's the original question verbatim: Lately I have replaced several home wireless routers because the signal strength has been found to be degraded. These devices, when new (2+ years ago) would cover an entire house. Over the years, the strength seems to decrease to a point where it might only cover one or two rooms. Of the three that I have replaced for friends, I have not found a common brand, age, etc. It just seems that after time, the signal strength decreases. I know that routers are cheap and easy to replace but I'm curious what actually causes this. I would have assumed that the components would either work or not work; we would either have a full signal or have no signal. I am not an electrical engineer and I can't find the answer online so I'm reaching out to you. Can someone explain how a transmitter can slowly go bad? Common (incorrect, but repeated) answers from slashdot include: Back then your neighbors didn't have wifi, now they do. They drowning you out. I don't think this is likely because replacing the access point with a new one and using the same frequencies solves the problem. Older devices had low transmit power. Crank that baby. As mentioned by a FreeBSD wireless developer this violates regulations and can physically damage the equipment. It was also mentioned that higher power in one direction is not necessarily reciprocated. This shows higher bars, but not necessarily a better connection. Manufacturers make cheap crap designed to wear out. This one actually may be legitimate although it is overly broad. What specifically causes damage over time? Heat? Excessive power? So can anyone provide an informed answer on this? Is there any way to fix these older access points?
