• change browser to open weblinks in thunderbird

  - by Bevor

  Hello, because it's almost obvious that either Thunderbird or Firefox freeze my whole system after some time, I'd like to not use FF at the moment and let Thunderbird run only for a short time as long as I check e-mails. Thunderbird web links should be opened with opera from now. For that I went in Thunderbird to Preferences-Advanced-General-Config Editor and set the following: network.protocol-handler.app.http -> /usr/bin/opera network.protocol-handler.app.https -> /usr/bin/opera network.protocol-handler.warn-external.ftp -> true network.protocol-handler.warn-external.http -> true network.protocol-handler.warn-external.https -> true Moreover I changed in Gnome in System-Preferences-Prefered Applications Opera as webbrowser and I checked in FF that it should warn if FF is not the default browser (obviously it isn't anymore). Unfortunately all of these settings doesn't work. Thunderbird still opens web links with FF. Any explantions why? (I already restarted Thunderbird although I don't have to, but no effect)

• I'm applying for a position at a startup. To whom should I address my cover letter?

  - by sapphiremirage

  One of the co-founders answered questions about the company when the job was posted, but I feel like I shouldn't assume that he's the one who is in charge of hiring. Since it's relatively new and has a lot of name overlap with other things already on the web, it's hard to find any information about the company online, much less the name of their hiring manager. I'm not even certain that they do have a hiring manager, since I seem to remember that they are just an 8 person team. I've heard that "To whom it may concern" is tacky, and normally I would say something along the lines of "Dear Head of Human Resources", but that clearly doesn't work in this case. Any idea what my salutation should be? Later Edits: Final Version: To Joe Programmer and/or the AwesomeStartup.com hiring team, (+ a few words in first paragraph explaining why I am addressing Joe Programmer) I've already sent the email, so nothing you say here will save me. However, feel free to comment on my decision if you think your words be useful to future generations. Old Version (left here because some people responded to it): To the hiring manager for internships at Awesomestartup.com, Additionally, because so many people made comments about the content of my letter: I did spent several hours writing the cover letter itself and making sure that it was awesome. After spending such a long time working on the important part, I asked this question because I wanted to make sure that it wouldn't get passed over by some human who was having a bad day and decided that my salutation was inappropriate. Not likely when the most likely reader of that email is a programmer type, I know, but I figured that it wouldn't hurt not to be sloppy.

• Stuck on Login PhpMyAdmin

  - by TMP

  Hi. I've isntalled phpmyadmin via apt-get. I've set the apache env-vars to the correct user:group. I've set ownership of /etc/apache2 and /etc/phpmyadmin to this user:group. I've restarted both apache2 and mysql several times. My Problem: When I access [ServerIP]/phpmyadmin I get the login screen, I enter the information, and i'm right back at the login screen, with not even an error "permission denied" or "password wrong" or whatever. The only things thats different is the URL: Instead of the Original http://[ServerIP]/phpmyadmin/index.php I am now at http://[ServerIP]/phpmyadmin/index.php?token=[Long Hex string here] However, still the login dialog. My Question: How Do I fix this?

• ASP.NET MVC 3 (C#) Software Architecture

  - by ryanzec

  I am starting on a relatively large and ambitious ASP.NET MVC 3 project and just thinking about the best way to organize my code. The project is basically going to be a general management system that will be capable of supporting any type management system whether it be a blogging system, cms, reservation system, wikis, forums, project management system, etc…, each of them being just a separate 'module'. You can read more about it on my blog posted here : http://www.ryanzec.com/index.php/blog/details/8 (forgive me, the style of the site kinda sucks). For those who don't want to read the long blog post the basic idea is that the core system itself is nothing more than a users system with an admin interface to manage the users system. Then you just add on module as you need them and the module I will be creating is a simple blog post to test it out before I move on to the big module which is a project management system. Now I am just trying to think of the best way to structure this so that it is easy for users to add in there own modules but easy for me to update to core system without worrying about the user modifying the core code. I think the ideal way would be to have a number of core projects that user is specifically told not to modify otherwise the system may become unstable and future updates would not work. When the user wants to add in there own modules, they would just add in a new project (or multiple projects). The thing is I am not sure that it is even possible to use multiple projects all with their own controllers, razor view template, css, javascript, etc... in one web application. Ideally each module would have some of it own razor view templates, css, javascript, image files and also need access to some of the core razor view templates, css, javascript, image files which would is in a separate project. It is possible to have 1 web application run off of controllers, razor view templates, css, javascript, image files that are store in multiple projects? Is there a better was to structure this to allow the user to easily add in module with having to modify the core code?

• Single hardware unit to protect web servers and implement smart publishing

  - by Maxim V. Pavlov

  Thus far we've been using the combination of Forefront TMG 2010 as an edge firewall + intrusion prevention system + web site publishing mechanism in the data center to work with a few web server machines. Since we develop on ASP.NET, we are IIS and in general - Microsoft crowd. Since TMG is being deprecated, we need to come up with a hardware alternative to protect and serve our data center web cloud. Could you please advise a hardware or virtual appliance solution that can provide routing, flood prevention and smart web-site publishing (one IP - many web sites based on domain name filter) all in one. Even if it is hard to configure, as long as it covers all these features, we will invest to learn and replace TMG eventually.

• Ubuntu: Alternative task-switcher to what is provided in compiz

  - by user22106

  I'm running Ubuntu 11.04 and really enjoying it. The task switcher default in Ubuntu shows a list of small icons for each running app much like the windows task switcher. It's fast and effective. I enabled Compiz and noticed that the task switcher changed to one with small thumbnails showing a smaller version of each window. Nice, but it slows the task manager down to about 0.5 seconds to display, which for me is far too long. Have googled the forums and it's a very common problem with ubuntu/compiz. I want to run compiz as it provides so many other features, but the slow task switcher is just not going to run with me. So was wondering if there is some way of NOT letting compiz override the task switcher, or, if there is some other task switcher that I can install which will not be slow like the compiz one. Any help would be appreciated.

• Huwawei E220 broadband dongle not working

  - by Roshnal

  The problem is, I have used Ubuntu from 6.10 upto 11.10. And upto 11.04 I used my same USB 3G dongle to connect to broadband and it worked fine. But 2 days ago I upgraded to Ubuntu 11.10 and broadband is not working. It detects my dongle and creates a connection without a problem, but when connecting it just keeps on and on for a long time and then say I'm offline. So I did a clean install and the same thing occurred. But I also have a netbook and its got Ubuntu 11.10. I tried using the same dongle for internet on that netbook and it worked fine without any issues. But this isn't a problem with my USB port on my main machine or something like that because I'm also using Windows on my main machine (dual-boot) and its working fine. My hardware: Main computer (one that I'm trying to connect): 2.8GHz dual core Intel 2GB RAM 500GB Sata II HDD 384MB Video Memory (Intel G31/G33 chipset) Ubuntu 11.10 (32bit) My NetBook (broadband working fine): 1.6GHz Intel Atom (dual core) 1GB DDR3 RAM 250GB HDD 128MB Video Memory (Intel something-I-can't-remember) Ubuntu 11.10 (32bit) My dongle is a Huawei E220 and ISP is Dialog GSM (I'm in Sri Lanka) So any idea why this is? I really love Ubuntu and this is bugging me off.. Any help greatly appreciated. Regards, Roshnal

• telnet - is there a maximum line limit?

  - by benc

  I am working on several servers that use HTTP for transport of commands. What I have encountered is that some of the commands I am trying to issue by hand are very long GETs, several lines, and that when I telnet from my Mac to my Solaris system, I cannot seem to cut and paste the line successfully. I get a couple bounching sounds (which I assume is a control-g - bell) and then it never pastes everything. From trying to break it up into smaller pieces, I am getting the impression that TELNET, or my bundled telnet client or server has a maximum line length that I had never bumped into. I did some googling and superusering, but did not find anything definitive.

• Why is my query soooooo slow?

  - by geekrutherford

  A stored procedure used in our production environment recently became so slow it cause the calling web service to begin timing out. When running the stored procedure in Query Analyzer it took nearly 3 minutes to complete.   The stored procedure itself does little more than create a small bit of dynamic SQL which calls a view with a where clause at the end.   At first the thought was that the query used within the view needed to be optimized. The query is quite long and therefore easy to jump to this conclusion.   Fortunately, after bringing the issue to the attention of a coworker they asked "is there a where clause, and if so, is there an index on the column(s) in it?" I had no idea and quickly said as much. A quick check on the table/column utilized in the where clause indicated indeed there was no index.   Before adding the index, and after admitting I am no SQL wiz, I checked the internet for info on the difference between clustered and non-clustered indexes. I found the following site quite helpful OdeToCode. After adding the non-clustered index on the column, the query that used to take nearly 3 minutes now takes 10 seconds! Ah, if only I'd thought to do this ahead of time!

• Setting up a shared media drive

  - by Sam Brightman

  I want to have a shared media drive be transparently usable to all users, whilst also sticking to FHS and Ubuntu standards. The former takes priority if necessary. I currently mount it at /media/Stuff but /media is supposed to be for external media, I believe. The main issue is setting permissions so that access to read and write to the drive can be granted to multiple users working within the same directories. InstallingANewHardDrive seems both slightly confused and not what I want. It claims that this sets ownership for the top-level directory (despite the recursion flag): sudo chown -R USERNAME:USERNAME /media/mynewdrive And that this will let multiple users create files and sub-directories but only delete their own: sudo chgrp plugdev /media/mynewdrive sudo chmod g+w /media/mynewdrive sudo chmod +t /media/mynewdrive However, the group writeable bit does not seem to get inherited, which is troublesome for keeping things organised (prevents creation inside sub-folders originally made by another user). The sticky bit is probably also unwanted for the same reason, although currently it seems that one userA (perhaps the owner of the mount-point?) can delete the userB's files, but not vice-versa. This is fine, as long as userB can create files inside the directory of userA. So: What is the correct mount point? Is plugdev the correct group? Most importantly, how to set up permissions to maintain an organised media drive? I do not want to be running cron jobs to set permissions regularly!

• Two graphical entities, smooth blending between them (e.g. asphalt and grass)

  - by Gabriel Conrad

  Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

• how do i automatically add a new route to the routing table?

  - by Robbie Mckennie

  I'm looking at linking two networks with a long range Ethernet bridge. I know I can connect my two networks with a router, but my problem is how will my computers know where to send packets if I don't add the route manually? I COULD add them manually, but it seems like a hassle. I have very very limited knowledge of RIP (I know it has something to do with routing), but I don't know how to use it. edit: My vision for the network would be the 2 networks (which are currently independent home networks), connected by a microwave Ethernet link. I assumed i'd need a router on one end of the bridge, to handle communication between the 2 networks.

• Platform game collisions with Block

  - by Sri Harsha Chilakapati

  I am trying to create a platform game and doing wrong collision detection with the blocks. Here's my code // Variables GTimer jump = new GTimer(1000); boolean onground = true; // The update method public void update(long elapsedTime){ MapView.follow(this); // Add the gravity if (!onground && !jump.active){ setVelocityY(4); } // Jumping if (isPressed(VK_SPACE) && onground){ jump.start(); setVelocityY(-4); onground = false; } if (jump.action(elapsedTime)){ // jump expired jump.stop(); } // Horizontal movement setVelocityX(0); if (isPressed(VK_LEFT)){ setVelocityX(-4); } if (isPressed(VK_RIGHT)){ setVelocityX(4); } } // The collision method public void collision(GObject other){ if (other instanceof Block){ // Determine the horizontal distance between centers float h_dist = Math.abs((other.getX() + other.getWidth()/2) - (getX() + getWidth()/2)); // Now the vertical distance float v_dist = Math.abs((other.getY() + other.getHeight()/2) - (getY() + getHeight()/2)); // If h_dist > v_dist horizontal collision else vertical collision if (h_dist > v_dist){ // Are we moving right? if (getX()<other.getX()){ setX(other.getX()-getWidth()); } // Are we moving left? else if (getX()>other.getX()){ setX(other.getX()+other.getWidth()); } } else { // Are we moving up? if (jump.active){ jump.stop(); } // We are moving down else { setY(other.getY()-getHeight()); setVelocityY(0); onground = true; } } } } The problem is that the object jumps well but does not fall when moved out of platform. Here's an image describing the problem. I know I'm not checking underneath the object but I don't know how. The map is a list of objects and should I have to iterate over all the objects??? Thanks

• My internet connection slows or dies unexpectedly

  - by genesis

  I installed Ubuntu 10.04 once again and I'm having some problems which I had before, but I have no idea how I solved them. On Windows, everything's working fine and I had no problems with this. My problem is that sometimes, when browsing through the internet, webpages just start to load really slow, sometimes it doesn't load anything at all (Error 118 (net::ERR_CONNECTION_TIMED_OUT): The operation timed out.) and it starts to work after few minutes. My IPv4 settings are automatic (DHCP), and IPv6 settings are Ignored/Disabled. I think my previous problems had something to do with IPv6, but I'm not sure.

• Knowing state of game in real time

  - by evthim

  I'm trying to code a tic tac toe game in java and I need help figuring out how to efficiently and without freezing the program check if someone won the game. I'm only in the design stages now, I haven't started programming anything but I'm wondering how would I know at all times the state of the game and exactly when someone wins? Response to MarkR: (note: had to place comment here, it was too long for comment section) It's not a homework problem, I'm trying to get more practice programming GUI's which I've only done once as a freshman in my second introductory programming course. I understand I'll have a 2D array. I plan to have a 2D integer array where x would equal 1 and o would equal 0. However, won't it take too much time if I check after every move if someone won the game? Is there a way or a data structure or algorithm I can use so that the program will know the state (when I say state I mean not just knowing every position on the board, the int array will take care of that, I mean knowing that user 1 will win if he places x on this block) of the game at all times and thus can know automatically when someone won?

• Html 5 clock, part ii - CSS marker classes and getElementsByClassName

  - by Norgean

  The clock I made in part i displays the time in "long" - "It's a quarter to ten" (but in Norwegian). To save space, some letters are shared, "sevenineight" is four letters shorter than "seven nine eight". We only want to highlight the "correct" parts of this, for example "sevenineight". When I started programming the clock, each letter had its own unique ID, and my script would "get" each element individually, and highlight / hide each element according to some obscure logic. I quickly realized, despite being in a post surgery haze, …this is a stupid way to do it. And, to paraphrase NPH, if you find yourself doing something stupid, stop, and be awesome instead. We want an easy way to get all the items we want to highlight. Perhaps we can use the new getElementsByClassName function? Try to mark each element with a classname or two. So in "sevenineight": 's' is marked as 'h7', and the first 'n' is marked with both 'h7' and 'h9' (h for hour). <div class='h7 h9'>N</div><div class='h9'>I</div> getElementsByClassName('h9') will return the four letters of "nine". Notice that these classes are not backed by any CSS, they only appear directly in html (and are used in javascript). I have not seen classes used this way elsewhere, and have chosen to call them "marker classes" - similar to marker interfaces - until somebody comes up with a better name.

• Sometimes tabs in notepad++ won't make a new window when dragged out

  - by darenw

  Long-time Linux user on a Windows 7 machine, using Notepad++ to edit multiple text files. Sometimes I can drag a tab out of the notepad++ window onto the desktop to get a new notepad++ window. This is a very nice feature. But sometimes when I try to drag a tab out, nothing happens. I don't see what is different about these tabs or the files they contain. It is repeatable; the same tab still won't make a new window. I'm not familiar enough with Windows and its strange ways to begin to guess what is going on, unless it's a bug. How can I make all tabs draggable-to-new-windowable, no exceptions?

• Sucking Less Every Year ?

  - by AdityaGameProgrammer

  Sucking Less Every Year A trail of thought that had been on my mind for a while Quoting directly from the post I've often thought that sucking less every year is how humble programmers improve. You should be unhappy with code you wrote a year ago. If you aren't, that means either A) you haven't learned anything in a year, B) your code can't be improved, or C) you never revisit old code. All of these are the kiss of death for software developers. How often does this happen or not happen to you? How long before you see an actual improvement in your coding ? month, year? Do you ever revisit Your old code? How often does your old code plague you? or how often do you have to deal with your technical debt. It is definitely very painful to fix old bugs n dirty code that we may have done to quickly meet a deadline and those quick fixes ,some cases we may have to rewrite most of the application/code. No arguments about that. Some of the developers i had come across argued that they were already at the evolved stage where their coding doesn't need improvement or cant get improved anymore. Does this happen? If so how many years into coding on a particular language does one expect this to happen?

• Why is Ubuntu One slow to sync in 11.10, either backup or any sub-folder contents?

  - by pst007x

  I have been trying to sync my documents folder of 1.4GB, it still hasn't worked and it has been syncing for a month. The top level syncs, files and folders in the Document folders, but contents of sub-folders just hang. (Gave up and stopped syncing this folder) However,I have tried using the backup facility in 11.10, to backup to Ubuntu One.... I upgraded my HDD space in Ubuntu One. It has been going now for 24hours-ish and only backed up what looks like a couple of percent. (By the way what an excellent idea to backup to Ubuntu One, if only we could get it to actually work! :-o) The odd thing is I can sync to drop box within hours, rather than months. This is bad, and has been an issue since Ubuntu One's release. I have reported this problem and there were promises in later releases this would be fixed, but it hasn't. Canonical cannot help either... I posted on several blogs, a lot of people have the same problem but no fixes. So do I use dropbox or another service, until it is sorted, as Ubuntu does not seem to see this as an issue, I think a fix will be a long time in coming. (However,I love the potential of Ubuntu One and the integration with the OS) Yes my internet speeds are fine, etc... :-) No firewall (sudo ufw status: STATUS: INACTIVE), No Proxy, etc NB: I have raised this as a separate question to others posted here, because my question relates to Ubuntu 11.10, though I have commented elsewhere for help. Plus my question also relates to deja-dup backup to Ubuntu One. Thanks

• How can a single disk in a hardware SATA RAID-10 array bring the entire array to a screeching halt?

  - by Stu Thompson

  Prelude: I'm a code-monkey that's increasingly taken on SysAdmin duties for my small company. My code is our product, and increasingly we provide the same app as SaaS. About 18 months ago I moved our servers from a premium hosting centric vendor to a barebones rack pusher in a tier IV data center. (Literally across the street.) This ment doing much more ourselves--things like networking, storage and monitoring. As part the big move, to replace our leased direct attached storage from the hosting company, I built a 9TB two-node NAS based on SuperMicro chassises, 3ware RAID cards, Ubuntu 10.04, two dozen SATA disks, DRBD and . It's all lovingly documented in three blog posts: Building up & testing a new 9TB SATA RAID10 NFSv4 NAS: Part I, Part II and Part III. We also setup a Cacit monitoring system. Recently we've been adding more and more data points, like SMART values. I could not have done all this without the awesome boffins at ServerFault. It's been a fun and educational experience. My boss is happy (we saved bucket loads of $$$), our customers are happy (storage costs are down), I'm happy (fun, fun, fun). Until yesterday. Outage & Recovery: Some time after lunch we started getting reports of sluggish performance from our application, an on-demand streaming media CMS. About the same time our Cacti monitoring system sent a blizzard of emails. One of the more telling alerts was a graph of iostat await. Performance became so degraded that Pingdom began sending "server down" notifications. The overall load was moderate, there was not traffic spike. After logging onto the application servers, NFS clients of the NAS, I confirmed that just about everything was experiencing highly intermittent and insanely long IO wait times. And once I hopped onto the primary NAS node itself, the same delays were evident when trying to navigate the problem array's file system. Time to fail over, that went well. Within 20 minuts everything was confirmed to be back up and running perfectly. Post-Mortem: After any and all system failures I perform a post-mortem to determine the cause of the failure. First thing I did was ssh back into the box and start reviewing logs. It was offline, completely. Time for a trip to the data center. Hardware reset, backup an and running. In /var/syslog I found this scary looking entry: Nov 15 06:49:44 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_00], 6 Currently unreadable (pending) sectors Nov 15 06:49:44 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_07], SMART Prefailure Attribute: 1 Raw_Read_Error_Rate changed from 171 to 170 Nov 15 06:49:45 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_10], 16 Currently unreadable (pending) sectors Nov 15 06:49:45 umbilo smartd[2827]: Device: /dev/twa0 [3ware_disk_10], 4 Offline uncorrectable sectors Nov 15 06:49:45 umbilo smartd[2827]: Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error Nov 15 06:49:45 umbilo smartd[2827]: # 1 Short offline Completed: read failure 90% 6576 3421766910 Nov 15 06:49:45 umbilo smartd[2827]: # 2 Short offline Completed: read failure 90% 6087 3421766910 Nov 15 06:49:45 umbilo smartd[2827]: # 3 Short offline Completed: read failure 10% 5901 656821791 Nov 15 06:49:45 umbilo smartd[2827]: # 4 Short offline Completed: read failure 90% 5818 651637856 Nov 15 06:49:45 umbilo smartd[2827]: So I went to check the Cacti graphs for the disks in the array. Here we see that, yes, disk 7 is slipping away just like syslog says it is. But we also see that disk 8's SMART Read Erros are fluctuating. There are no messages about disk 8 in syslog. More interesting is that the fluctuating values for disk 8 directly correlate to the high IO wait times! My interpretation is that: Disk 8 is experiencing an odd hardware fault that results in intermittent long operation times. Somehow this fault condition on the disk is locking up the entire array Maybe there is a more accurate or correct description, but the net result has been that the one disk is impacting the performance of the whole array. The Question(s) How can a single disk in a hardware SATA RAID-10 array bring the entire array to a screeching halt? Am I being naïve to think that the RAID card should have dealt with this? How can I prevent a single misbehaving disk from impacting the entire array? Am I missing something?

• See network computer description in Explorer

  - by John Gardeniers

  When viewing the list of network computers in Windows Explorer on a Win 7 machine there appears to be no way of readily seeing the description field, which makes that pretty well useless. I believe this problem started with Vista but I'm seeing it for the first time because I was fortunate enough to skip over Vista. We're currently rolling out Win 7 on new boxes and although I'm changing the naming system to something more sensible, the old boxes have names such as FWS01, FWS02, etc. Managing a network of computers with such names is made more difficult when you can't readily see who's machine each one is. Googling the problem brought up a workaround involving creating a shortcut on an XP machine and copying that to the Win 7 box but that's a long way from ideal. Is there some kind of hack that can be applied to machines, the operator of which needs to be able to see the description field?

• Effect of using dedicated NVidia card instead of Intel HD4000

  - by Sman789

  Short version: Can someone please advise me of the effect of adding a dedicated NVIDIA GeForce GT 630M card to an Ubuntu laptop in terms of power consumption and performance gains/losses when doing general productivity tasks and booting up. Also, how good are the closed source, open source, and Bumblebee drivers for these newer cards compared to support for the Intel HD4000? Long version/Background, if any info here is helpful: I'm thinking of ordering a laptop from PC Specialist (a UK company who actually sell machines without Windows pre-installed) with the following specifications: Genesis IV: 15.6" AUO Matte 95% Gamut LED Widescreen (1920x1080) Intel® Core™i5 Dual Core Mobile Processor i5-3210M (2.50GHz) 3MB 4GB SAMSUNG 1600MHz SODIMM DDR3 MEMORY (1 x 4GB) 120GB INTEL® 520 SERIES SSD, SATA 6 Gb/s (upto 550MB/sR | 520MB/sW) Intel 2 Channel High Definition Audio + MIC/Headphone Jack GIGABIT LAN & WIRELESS INTEL® N135 802.11N (150Mbps) + BLUETOOTH Now, as I want this laptop mainly for work and not for games, I would be more than content with the HD4000 integrated chip which comes with the processor. However, for compatibility reasons, I am not able to get the specs I want unless I choose a NVIDIA GeForce GT 630M 1GB graphics card, which I don't have a great deal of use for. I'm willing to buy it, however, as it's still cheaper than any other laptop with the specs I want. However, I know that Linux power management isn't fantastic with open-source graphics drivers, and I don't much about Bumblebee. Basically, whilst I'm happy to 'tolerate' the card being there, I don't want to experience any negative effects on the rest of my system (battery, performance etc) and if there are likely to be any, I might reconsider my purchase. So if anyone can advise me on the effects, I would be very grateful, since I doubt I can just turn the card off. Thankyou for any assistance :)

• Dealing with three Windows partitions in dual boot installation

  - by Tim

  For dual-boot installation of Ubuntu after Windows. Quoted from ubuntuguide If a Windows boot partition exists as a second NTFS partition, it should be left alone. If there is a Windows recovery partition also installed, it can also be left alone as long as there are only two NTFS partitions total on the hard drive (i.e. there is no NTFS boot partition as well). If there are a total of 3 NTFS partitions on the hard drive, then the third Windows NTFS partition (the recovery partition) should be removed after creating Recovery CDs from it (see here). In the last case where Windows has three partitions, I was wondering why it says the recovery partition shall be removed? Is it possible to keep the three and create another extended partition with several logical partitions for installing Ubuntu and dual-booting the two OSes? I plan to dual-boot install Ubuntu 10.04 with existing Windows 7. Following is the layout of the current partitions of my hard drive viewed from Windows 7: So must I remove the Lenovo_Recovery (Q:) partition for the same reason you give for the first question? Thanks and regards!

• Companies and Ships

  - by TechnicalWriting

  I have worked for small, medium, large, and extra large companies and they have something in common with ships. These metaphors have been used before, I know, but I will have a go at them.The small company is like a speed boat, exciting and fast, and can turn on a dime, literally. Captain and crew share a lot of the work. A speed boat has a short range and needs to refuel a lot. It has difficulty getting through bad weather. (Small companies often live quarter to quarter. By the way, if a larger company is living quarter to quarter, it is taking on water.)The medium company is is like a battleship. It can maneuver, has a longer range, and the crew is focused on its mission. Its main concern are the other battleships trying to blow it out of the water, but it can respond quickly. Bad weather can jostle it, but it can get through most storms.The large company is like an aircraft carrier; a floating city. It is well-provisioned and can carry a specialized load for a very long range. Because of its size and complexity, it has to be well-organized to be effective and most of its functions are specialized (with little to no functional cross-over). There are many divisions and layers between Captain and crew. It is not very maneuverable; it has to set its course well in advance and have a plan of action.The extra large company is like a cruise liner. It also has to be well-organized and changes in direction are often slow. Some of the people are hard at work behind the scenes to run the ship; others can be along for the ride. They sail the same routes over and over again (often happily) with the occasional cosmetic face-lift to the ship and entertainment. It should stay in warm, friendly waters and avoid risky speed through fields of ice bergs.I have enjoyed my career on the various Ships of Technical Writing, but I get the most of my juice from the battleship where I am closer to the campaign and my contributions have the greater impact on success.Mark Metcalfewww.linkedin.com/in/MarkMetcalfe

• Enable Ctrl (or Alt) + arrow keys to mimic 'home' and 'end' functionality

  - by YuKagi

  I am a long time Mac user and I'm now using a Ubuntu machine for development, and while I'm more or less used to a lot of the keyboard shortcuts, one thing I can't get used to is using the 'Home' and 'End' keys to move around lines of text. On a Mac you use "Command + right arrow" to go to the end of a line and "Command + left arrow" to go to the beginning. Is there a way to enable this kind of functionality in Linux? I'm not sure if this would be considered remapping, keyboard shortcuts, or what...
