• 12.10 Wireless networking

  - by user108594

  I downloaded ubuntu 12.10 using WUBI and cannot connect to the internet. I removed it and downloaded ubuntu 12.04 still cannot connect. This I assume rules out the program being the problem. I reinstalled 12.10. When loaded I get the same message W/red (x) stating Internet not connected. I went to the Settings drop down box and it does not reveal the network list but (enable networking has a ck mark). Am running a HP Laptop with a w/7/64 OS that has a kill switch that indicates (orangeno connection) I downloaded 12.10 on my desktop (on the same network) and everything OK. I tried to follow the instructions in the help menu but got lost and confused . Sincerely Dan Additional Info per request Broadcom 802.11b/g Wlan Internal pc [hp laptop] P.S. I've been out of town for about a month. TKS for your gitback I did install 12.10 via cd and everything ok,but retried alongside 7 and unable to connect to internet,also took laptop and hard wired using ethernet cable and everything ok. stumped again and running out of ideas!!!

• Grub2 attempting to boot hd1 when it should boot hd0

  - by JoBu1324

  I'm attempting to perform a "normal" install on a USB3 SSD (I don't know if it is noteworthy, but I don't have a swap partition). The installation proceeds normally (I'm installing from a USB2 device I created using LiLi Boot, with a copy of Ubuntu 12.10 64bit that I downloaded directly from the source. The system I'm running Ubuntu on has had a more traditional installation of ubuntu running on it without issue (also 12.10), so I know that everything works A-OK when booting from a 7200RPM internal disk. There are a number of oddities that I've noticed so far, including graphics corruption, but the first and most pressing issue is that Grub2 refuses to recognize the correct hd. From /boot/grub/grub.cfg: if [ x$feature_default_font_path = xy ] ; then font=unicode else insmod part_msdos insmod ext2 set root='hd1,msdos1' if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd1,msdos1 --hint-efi=hd1,msdos1 --hint-baremetal=ahci1,msdos1 b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 else search --no-floppy --fs-uuid --set=root b58ee4f7-d41d-400a-b7b8-18bd1f0ae9d3 fi font="/usr/share/grub/unicode.pf2" fi This is from a 100% fresh install of linux (first boot), which was installed while no hard drives were connected to the system, other than the USB2 LiLi drive. The system refuses to boot unless I change the hd1,msdos1 - hd0,msdos1 in the grub menu at boot, when it is the only disk device connected to the PC. What options are left for me to troubleshoot this issue? I've been racking my brains and taxing the internet trying to dig up something on this problem, but now I'd like to see if the Ubuntu community can rise to the challenge and help me fix this boot problem. This is the second time I've attempted this particular setup. The first time, after days of wasted time, I managed to get it to boot every other boot - i.e. every even boot it would boot into Ubuntu like it was happy; every odd boot it would boot into the BusyBox or Grub prompt. At one point it complained that it couldn't find /dev/disk/by-uuid/[the disk], which I found most perplexing, since the disk was there and booted before and after the occurrence (with intervention).

• How to get "Fn" keys to work (Asus 4830T)? (specificly, the "suspend" key)

  - by Pointy

  I've got an Asus 4830T onto which I've just re-installed 12.04 because I installed an SSD. I was running 12.04 before too, which had been upgraded over a few releases. At some point on that old install, I had gotten all the "Fn" keys to work, or at least all the ones I cared about. (Oh except I think the screen brightness keys never worked.) I have no recollection of what I did. Anyway now things are fine, and some of the Fn keys work: the one to turn of the trackpad and the one to turn off wireless (grr I hate that one). However, the "suspend" key for some reason does not work. Now the system will suspend and resume just fine, but I'm having to do it from the menu. Is there an easy (or hard) way to make those work? I'm running straight Ubuntu but with Xfce installed as my normal desktop. (In other words, it's not Xubuntu, though I doubt it matters.) I recall at some point having found some arcane mapping mechanism to bind the Fn keys to actions, but I can't find it now. (I'm perfectly OK with editing weird files; I'm a long-time Unix user.) (Very long-time.)

• Randomly Freezes - How Can I Diagnose the Problem?

  - by j0rd4n

  At random times, Ubuntu 10.04 freezes, and I have to do a hard shutdown. It was upgraded from 9.10 which didn't freeze. First, is this is common problem with a quick answer, and if not, what can I do to diagnose it? I've tried checking application/kernel logs, but nothing gives me a clue as to what caused the problem. My guess, is that since the OS froze, no logs could be updated. Ideas? SOLUTION: Solved it. My particular problem was my graphics card (integrated Radeon 9000 series). netconsole revealed I was getting the error: "reserve failed for wait". After trial-and-error, I manually configured my video card and disabled hardware acceleration. Completely fixed the issue. Here is what I did: Manually Created xorg.conf Ubuntu automatically configures xorg.conf and doesn't use a file. To edit this file, you have to tell Ubuntu to explicitly create one and then edit it. Here are the steps: Restart system Hold Shift as GRUB boots Select root terminal in GRUB login menu Execute: X -config xorg.conf.new Copy: cp xorg.conf.new /etc/X11/xorg.conf Disable Hardware Acceleration The following is specific to my Radeon card, but I'm sure other cards have a similar setup. Edit xorg.conf Find "Device" section for graphics card Uncomment "NoAccel" option and set to "True" Save + reboot Hope that helps.

• Fosfor EPUB Reader

  - by Geertjan

  Instead of creating a fullblown NetBeans Platform application for doing WYSIWYG editing for EPUB, similar to Sigil, I decided to focus purely on the very narrow scope of EPUB reading. The scope is narrower and, since the application will be a lot less ambitious and smaller, a pure JavaFX implementation makes sense. When you somehow get, e.g., buy, an EPUB file, you typically read it on a tablet or mobile device. However, some people in the world, e.g., me, still have laptops. Therefore, I'm creating a small JavaFX application that unzips EPUB files, into a temp directory, and then loads them into a JavaFX WebView. Arabic support: For an application like this, simplicity is the most important thing. Very few buttons, very few options, preferably no configuration of anything. Just let the user open the EPUB file and read it, that's it, nothing fancy. CSS stylesheets and images are correctly read. It's exactly what it looks like, a reader for EPUB files. The back and forward buttons are working and you can also switch to the table of contents. When it is complete, which it pretty much is right now, publishers of EPUB files can make this small app available from their site, to simplify life for their readers, since it will run easily and well on all operating systems.

• Advice on reconciling discordant data

  - by Justin

  Let me support my question with a quick scenario. We're writing an app for family meal planning. We'll produce daily plans with a target calorie goal and meals to achieve it for our nuclear family. Our calorie goal will be calculated for each person from their attributes (gender, age, weight, activity level). The weight attribute is the simplest example here. When Dad (the fascist nerd who is inflicting this on his family) first uses the application he throws approximate values into it for Daughter. He thinks she is 5'2" (157 cm) and 125 lbs (56kg). The next day Mom sits down to generate the menu and looks back over what the bumbling Dad did, quietly fumes that he can never recall anything about the family, and says the value is really 118 lbs! This is the first introduction of the discord. It seems, in this scenario, Mom is probably more correct that Dad. Though both are only an approximation of the actual value. The next day the dear Daughter decides to use the program and sees her weight listed. With the vanity only a teenager could muster she changes the weight to 110 lbs. Later that day the Mom returns home from a doctor's visit the Daughter needed and decides that it would be a good idea to update her Daughter's weight in the program. Hooray, another value, this time 117 lbs. Now how do you reconcile these data points? Measurement error, confidence in parties, bias, and more all confound the data. In some idealized world we'd have a weight authority of some nature providing the one and only truth. How about in our world though? And the icing on the cake is that this single data point changes over time. How have you guys solved or managed this conflict?

• getting started as a web developer [closed]

  - by kmote

  I have over 10 years of programming experience building (Windows-based) desktop applications and utilities (VC++, C#, Python). My goal over the next year is to start transitioning to web application development. I want to teach myself the fundamental tools and technologies that would be considered essential for building professional, online, interactive, visually-stunning, data-driven web apps -- the kind described in Google's recently released "Field Guide: Building Great Web Applications". So my question is, what are the primary, most commonly-used technologies that seasoned professionals will need in their tool belt in the coming years? My plan was to start coming up to speed in Javascript, HTML5, & CSS, and then to do a deep dive into ASP.NET and Ajax, along with SQL DBs. (I was surprised to not be able to find a single book at Amazon with a broad, general scope like this, which caused me to start second-guessing this approach.) So, seasoned professionals: am I on the right track? Are there some glaring omissions in my list? Or some unnecessary inclusions? I would welcome any book suggestions along these lines as well.

• Do your own design jobs and make it look professional

  - by Webgui

  Looks and design is becoming more and more important for customers and organizations event when we deal with internal enterprise applications. However,  many web developers who work on business apps end up not investing resources on the design. The reason may be that they ran out of time so with their client's pressure there was no choice but to skip past the design process. In some cases, especially in sall software houses, there are no trained professional designers and the developers have to do both jobs. Since designing web applications can be very complex and requires mastering several languages and concepts, unless a big budget was allocated to the project it is very hard to produce a professional custom design. For that exact reasons, Visual WebGui integrated Point & Click Design Tools within its Web/Cloud Development Platform. Those tools allow developers to customize the UI look of the applications they build in a visual way that is fairly simple and doesn't require coding or mastering HTML, CSS and JavaScript in order to design. The development tools also allow professional designers easier work interface with the developers and quicly create new skins. So if you are interested in getting your design job done much easier, you should probably tune in for about an hour and find out how.

• Javascript is not loading

  - by Oden

  Hey, I've got a problem with JavaScript under Ubuntu, that drives me crazy. I'm using Gedit for my web sites since I'm an Ubuntu user. When I start a new website I create (usually with the gnome terminal) folder structure, and I copy the files I need into them. The next step is creating an index.html where I build the design and basic JavaScript functionality. JavaScript is stored in a sub-folder of the project and when i try to load one using the tag in the header, my whole page body disappears. If the source contains a script tag with its own body, and its not the first its code wont run. I've tried to solve the problem by setting chmod to 777 with sudo chmod -R 777 . but nothing changed. CSS is loading correctly, but JS isn't. I'm using the newest version of apache, no mod_rewrite stuff, but i get the same problem when I run the html from file (file:///...) Do anyone know how to solve this problem?

• Blatant copyright theft

  - by Tom Gullen

  Found a user on the forum trying to solicit business for his website, a good user reported it and I checked the website out. Firstly and most dangerously it's attempting to sell our original software, which is open source. Our open source software is around 15mb big and he's serving a 50mb download and trying to sell it for $20. He's also stolen our CSS/images/site design in general which is all custom built. I attempted to open reasonable discussion with him, and he responded promptly saying he would remove offending materials if he could just have 3 days to sort it out which I accepted. I'm not sure what his plan was because everything on that site is offending material. Anyway he messaged back saying the site was offline, and it was, but it went back online shortly afterwards. It's pretty sickening that someone is selling open source work as their own, (the site about us page references him as the sole developer etc etc, it's unbelievable to read it). I want to shut it down, what are my options? I'm going to contact his domain registrar, web host, and Paypal (that's how he's selling the program). Any other ideas?

• How to turn off screen (DPMS) together with locking session in KDE?

  - by gertvdijk

  First of all, I'm aware a similar question for GNOME is asked here: "Switch off laptop backlight when locking screen". Objective I would like to turn off my screen on locking the session for power saving reasons. Actual problem Locking the screen on Kubuntu (KDE) inevitably triggers the screensaver as far as I can see. There's no screensaver option other than 'Blank screen' together with its background colour set to black that comes just close to my goal. It blanks the screen, but doesn't turn off the screen. Screen's backlight will still be on and not saving any power. Current workaround A workaround via a script + shortcut key is possible, however, it's just a workaround since it doesn't trigger on all ways to lock the session. Therefore, I think it should be possible to have it done more elegantly, for example by providing this option in KDE's configuration dialog of the screensaver. The workaround I am now using is the following. A script that locks the screen and turns off the screen: #!/bin/bash qdbus org.freedesktop.ScreenSaver /ScreenSaver Lock xset dpms force standby and let it run with a shortcut key via a custom menu entry. It works. Here's why I consider it to be a workaround rather than a solution. It doesn't work for other ways to trigger the locking of the session. My actual question(s) Do I need to touching/patching KDE's source? If not what are my options? If so, could someone point me to where I can get started? what do you think is the recommended place in the GUI for configuration? I'm using Kubuntu 12.04 and willing to upgrade to KDE 4.9 or waiting for the 12.10 release.

  - by Tom

  i have tried several times to install ubuntu using wubi, i can't use a disc as i have a notebook computer and there is no optical drive. the download and installation all seem to work well but whenever i try to boot ubuntu at the windows 7/ubuntu menu it comes up with this error screen. I have used both the C: drive and the D: drive to install Ubuntu several times each, it's always unsuccessful. "Windows has failed to start. a recent hardware or software change might be the cause. To fix the problem: Insert your windows installation disc and restart your computer Choose your language settings and then click 'next' Click repair your computer. If you do not have this disc, contact your system administrator or computer manufacturer for assistance.

• Velvet screen after grub selection

  - by Spleen

  After a fresh install of Ubuntu 11.10 64-bit, the boot seems to stop after selecting the ubuntu option (same with the rescue one) in the grub menu. At first I thought this was related to grub-efi, as I've had similar problems after a Ubuntu 11.04 update which replaced grub-efi with grub-pc and got me stuck on a "elf magic" grub console (https://bugs.launchpad.net/ubuntu/+source/apt/+bug/800910). While the 11.04 problem was resolved with a simple chroot and apt-get install from the live cd, that solution doesn't work this time. The drive with the bootloader is a sata3 ssd with 64 gb gpt (sdb1 20 mb efi boot partition fat16, sdb2 60 gb root ext4 and sdb3 4 gb swap) on a msi e350ia-e45 mainboard with a pair of 2 TB ext4 mbr drives for photos/music/movies. I've tried a few grub-install/update-grub with boot-directory sdb1 from chroot, but I cant seem to go anywhere. Even this guide: http://en.gentoo-wiki.com/wiki/Grub2#EFI (ofc I replaced grub2 with grub in the grub-install and efibootmgr commands) doesnt seem to get me anywhere. Any help or ideas are appeciated ;) edit: I guess its the combination of gpt/uefi that also seems to haunt f16 edit: same with 12.04 beta btw

• What are some best practices for minimizing code?

  - by CrystalBlue

  While maintaining the sites our development team has created, we have come across include files and plugins that have proven to be very useful to more then one part of our applications. Most of these modules have come with two different files, a normal source file and a min file. Seeing that the performance and speed of a page can be increased by minimizing the size of the file, we're looking into doing that to our pages as well. The problem that we run into is a lot of our normal pages (written in ASP classic) is a mix of HTML, ASP, Javascript, CSS, and include files. We have some pages that have their JS both in include files and in the page, depending on if the function is only really used in that page or if it's used in many other pages. For example, we have a common.js and an ajax.js file, both are used in a lot of pages, but not all of them. As well as having some functions in a page that doesn't really make sense to put into one master page. What I have seen a few other people do online is use one master JS file and place all of their javascript into that, minify it, gzip it, and only use that on their production server. Again, this would be great, but I don't know if that fully works for our purposes. What I'm looking for is some direction to go with on this. I'm in favor of taking all of our JS and putting it in one include file, and just having it included in every page that is hit. However, not every page we have needs every bit of JS. So would it be worth the compilation and minifying of the files into one master file and include it everywhere, or would it be better to minify all other files and still include them on a need-to-use basis?

• Dualboot (Win 8 / Ubuntu 13) is stuck at 'switching to clocksource'

  - by Daniel Puscht

  for days I have been crawling the web for solutions to my problem, but couln't find any. Here it is: I got a new Laptop (ASUS Vivobook S200E) with Win 8 OEM preinstalled. I wanted to create a dual-boot system with Ubuntu 13 next to it. I read about UEFI and that I have to turn of Secure Boot and use the existing EFI partition as bootloader for Ubuntu. So I did. I also ran boot-repair reinstalling the GRUB. The result is when I start the computer I get into the boot menu. So far, so good. When I pick Win everthing is fine. But when I choose Ubuntu (recovery) the system starts, but gets stuck at the line '[1.806366] Switching to clocksource tsc'. I already tried other versions of Ubuntu (12.04.2, 12.10). I played with boot-repair (using the recommended fix, setting everything manually). But nothing works. It's always the same issue. I read that it could be a problem concerning graphic drivers, but this I can hardly believe. If this is any help, boot-repair gave me this link to post in fora. http://paste.ubuntu.com/5810391/ Thanks for any help in advance

• Javascript Event in Innerhtml Resulting from PHP Server Script

  - by user144527

  I'm (very slowly) making a website, and I'm creating a search engine for the database, which is essential to organize the dependencies during data entry. Anyway, what I would like is to type a few keywords into a box, have a menu pop up with various search results, and have the box fill with the ID number of the selected entry when it's clicked. Currently, I have a document called search.php which fills a div called search-output using xmlhttp.open() and the innerhtml property. Everything is working perfectly except for filling the original search box with the ID number when clicking. My first attempt was to add an onclick event to each entry in the output from search.php. Unfortunately, I found that javascript inserted into innerhtml is not run for security reasons. I've been Googling for hours but haven't been able to find a solution. How can I get the original search text box to fill with the correct ID when I click it? Is what I'm doing a good setup for the results I desire, or is there a better way to integrate search features into data entry?

• Making document storage in Sharepoint a breeze (leave the Web UI behind)

  - by deadlydog

  Hey everyone, I know many of us regularly use Sharepoint for document storage in order to make documents available to several people, have it version controlled, etc.  Doing this through the Web UI can be a real headache, especially when you have multiple documents you want to modify or upload, or when IE isn’t your default browser.  Luckily we can access the Sharepoint library like a regular network drive if we like. Open Sharepoint in Internet Explorer (other browsers don’t support the Open with Explorer functionality), navigate to wherever your documents are stored, choose the Library tab, and then click Open with Explorer. This will open the document storage in Explorer and you can interact with the documents just like they were on any other network drive J  This makes uploading large numbers of documents or directory structures super easy (a simple copy-paste), and modifying your files nice and easy. As an added bonus, you can drag and drop that location from the address bar in Explorer to the Favorites menu so that it’s always easily accessible and you can leave the Sharepoint Web UI behind completely for modifying your documents.  Just click on the new favorite to go straight to your documents.   You can even map this folder location as a network drive if you want to have it show up as another drive (e.g N: drive). I hope you found this as useful as I did

• LiveCD/USB boot issues with Ubuntu 12.04 on blank drive

  - by Richek

  Not sure how common this issue is, or even how badly I may be missing something simple, but I am a first time usuer having some serious problems. Some background: old HDD running Windows 7 developed too many bad sectors and is bricked. I'm attempting to install Ubuntu 12.04 on a fresh 1TB drive by booting from a liveCD USB flash drive. I've not been able to get past the initial menu screen, however, as the process stalls out shortly after selecting an option (both boot from drive and install to drive). I've tried multiple USB drives as well as CDs, modified the boot order, flashed BIOS, and even tried booting with only the flash drive and the keyboard connected with the same results.Typically what I observe is that the OS begins what I think is compliling, listing drivers and components before freezing on one. When the keyboard is plugged in, its the keyboard driver, before I flashed BIOS, it was a BIOS related item, now its an unknown entry. The computer seems to be reading the drive (idicated by USB light flashing or CD drive reving) for roughly 10 minutes with no progress, followed by the drives going quiet. Some spec info: Motherboard: ASUS P5Q Pro, BIOS version 2102 (latest version), Intel chipset CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz help would be appriciated!

• Web dev/programmer with 4.5 yrs experience. Better for career: self-study or master's degree? [closed]

  - by Anonymous Programmer

  I'm a 28 year-old web developer/programmer with 4.5 years of experience, and I'm looking to jump-start my career. I'm trying to decide between self-study and a 1-year master's program in CS at a top school. I'm currently making 65K in a high cost-of-living area that is NOT a hot spot for technology firms. I code almost exclusively in Ruby/Rails, PHP/CodeIgniter, SQL, and JavaScript. I've slowly gained proficiency with Git. Roughly half the time I am architecting/coding, and half the time I am pounding out HTML/CSS for static brochureware sites. I'd like to make more more money while doing more challenging/interesting work, but I don't know where to start. I have an excellent academic record (math major with many CS credits, 3.9+ GPA), GRE scores, and recommendations, so I am confident that I could be admitted to a great CS master's program. On the other hand, there is the tuition and opportunity cost to consider. I feel like there are a number of practical languages/tools/skills worth knowing that I could teach myself - shell scripting, .NET, Python, Node.js, MongoDB, natural language processing techniques, etc. That said, it's one thing to read about a subject and another thing to have experience with it, which structured coursework provides. So, on to the concrete questions: What programming skills/knowledge should I develop to increase my earning potential and make me competitive for more interesting jobs? Will a master's degree in CS from a top school help me develop the above skills/knowledge, and if so, is it preferable to self-study (possibly for other reasons, e.g., the degree's value as a credential)?

• Emacs stops taking input when a file has changed on disk [migrated]

  - by recf

  I'm using Emacs v24.3.1 on Windows 8. I had a file change on disk while I had an Emacs buffer open with that file. As soon as I attempt to make a change to the buffer, a message appears in the minibuffer. Fileblah.txt changed on disk; really edit the buffer? (y, n, r or C-h) I would expect to be able to hit r to have it reload the disk version of the file, but nothing happens. Emacs completely stops responding to input. None of the listed keys work, nor do any other keys as far as I can tell. I can't C-g out of the minibuffer. Alt-F4 doesn't work, not does Close window from the task bar. I have to kill the process from task manager. Anyone have any idea what I'm doing wrong here? In cases it's various modes not playing nice with each other, for reference, my init.el is here. Nothing complex. Here's the breakdown: better-defaults (ido-mode, remove menu-bar, uniquify buffer `forward, saveplace) recentf-mode custom frame title visual-line-mode require final newline and delete trailing whitespace on save Markdown mode with auto-mode-alist Flyspell with Aspell backend Powershell mode with auto-mode-alist Ruby auto-mode-alist Puppet mode with auto-mode-alist Feature (Gherkin) mode with auto-mode-alist The specific file was a markdown file with Github-flavored Markdown mode and Flyspell mode enabled.

• What are some good ways for an intermediate programmer to build skills?

  - by Jordan

  Preface: I work mostly in Python, and Web Dev languages (HTML, CSS, Javascript and Jquery, PHP) I'm proficient at coding but I want to get better. In larger more advanced projects my programming skills break down. The more code there is the more trouble I have fitting all the pieces together. I understand syntax well, and I can catch and correct errors fairly easier. But the more advanced it gets the more I struggle. I believe I have a good understand of the basic and nuts and bolts of programming and I understand what's going on, but when it comes to larger projects, especially ones with heavy math involved my confidence flags and I start making mistakes. It's not that I can't do it, I'm just not used to doing it. Does anyone have any advice for someone who knows programming, but wants to get better? The only tutorials I can really find are beginner basic type stuff. Basically what I'm saying is I want to be confident when I'm tackling advanced projects, but I can't because I have little experience dealing with difficult situations.

• Weird Screen while booting to install, while installing and after the install...and then the "panic occured" error

  - by Klyn

  I've decided to install ubuntu but neither ubuntu or any other linux distro won't even get to the desktop screen or work after getting there. On windows 8, everything is just fine. my new video card works perfectly and I have no problem with anything about it. then when I try to boot from ubuntu with wubi or with usb everything goes like this: 1) Grub screen...no problem at all, colors are just fine everything looks okay 2) and then linux boot screen...weird background color, over the backround there are vertical stripes of red-orange dots. but on the ubuntu logo and text, there are no dots at all! -I mean its shape is perfect- 3) desktop is about the start but * vertical stripes of red colored dots are all over the unity screen*. then when I click on ubuntu's menu, it usually switches to black screen saying something about "panic occured"...and then it restarts or it gives no respond at all. problems started after putting hd 6570 video card on my asus m5a78lm-lx video card which has amd phenom II X4 processor on it. I've searched to find something but there was no similar question that's why I'm almost sure it is kind of unique. again, I'm writing on Windows 8 right now and everything works and looks perfect. so far I've updated bios and anyone knows anything to solve this?

• Ubuntu 11.10 loads from live usb fine, but boots to black screen from harddrive. Why?

  - by Estel

  A few days ago I had a hard drive failure, which was running Windows XP (32-bit) just fine. The second hard drive in my computer held a few unimportant files, so I formatted it in the Ubuntu setup and installed 11.10 without a hitch. I had been using it for about a week, but decided to install Windows 7 (64-bit) in order to utilize Networking with my home server (running Windows Server 2000). My system is 64-bit based, and thus I had no problems installing other than a basic RAM error that required me to remove my RAM down to a single stick. I played with the settings in Windows 7 for around an hour before I shut down. After reinstalling the RAM, Windows 7 would not boot. In this, I then assumed that something about my system was rejecting Win7 and I reinstalled Ubuntu. However, now Ubuntu (11.10) boots into black screen, and I've already attempted activating the grub menu with the shift key, and following steps listed here: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen but nothing seems to work. I've reinstalled twice now, with the same result each time. Now, the very odd part about this whole scenario is that the USB I installed from has no problems booting as a live USB. This puzzles me greatly, because the hard drive boots straight to black screen and the live USB loads normally. At this point, my only theory is that the boot sector of the hard disk was somehow corrupted with Win7, and that Ubuntu was unable to completely write through. I used Darik's Boot n Nuke to wipe the drive, but was met with an error, this also puzzles me because the hard disk has no promblems reading or writing. Any suggestions/comments are appreciated. If you have a theory, I will be more than happy to oblige.

• How to start Sharepoint Development - Resources wanted [closed]

  - by user1249641

  I'm a apprentice for software development here in good ol' Germany and I've been doing fairly well with c#, asp.net mvc, entity framework and LINQ so far. My superiors want me to focus solely on our intranet development and Sharepoint development. They don't provide me with any resources to start. No books, no co-workers with actual webpart-dev-experience, seminars and the likes. There for it's do it on your own or die. I bought a book and started working through it on my virtual machine messing with the infrastructure and everything i can get a grip on. My main problem however stays the actual development. I have managed to write 2 webparts which can be used as a rudimentary ticket system(using WSP Builder and SP2007). But there it stops. Are there any comprehensive step by step tutorials or blogs out there, like the asp.net tutorials on www.asp.net which take you by the hand go over each step with you? Starting with the basic classes, going over custom css implementation, Jquery/Javascript ajax and async calls? No matter how trivial, I appreciate every help and hint you can give.
