Photo Gallery Software - reads from a local directory - watches folder- user and group permissions

- by Darkflare

Use Case: Photos are organised in a folder structure by date (by software lightroom/picasa) Want to run a local webserver to host a web gallery from (already know how to run lamp etc) I want to be able to attach metadata to the photos (probably through a database not residing in the photos folder) such that they can be tagged/categoried/albumed without affecting the original photos I want to be able to assign permissions to different albums to set users I want the software to watch the photo source folder for changes so that new photos are indexed ready for applying metadata and albums. I'd like the software to handle the rendering of numerous file types (photo formats) as well as video formatts I am language agnostic so php/python heck even c#, just want software that forfills the requirements. The main reason I am asking this question here as I am unsure what this software would even be called so google searching is quite difficult! Thanks for reading.

keeping connection open all time in sql

- by Costi

I have developed a Windows application in c# in which multiple users can add some numbers and their name and can view the data entered. The problem that I have is that the sever is on my laptop and every time I log off or close my laptop, they are losing connection to the DB and can not add or view any more. It seems that the port is closed or something. Is there a way to keep the port and their connection established all the time even when I'm logging out?

Architecture for a site "blog"/"news reel"

- by DavidScherer

I really don't want to undertake handling blog/news posts within a site I'm working on and would much rather use some other software that's fairly bare-bones that will manage the posts and then I can just pull posts from the DB or an API. Does anyone have any experience with a nice, lightweight OS Blog type software that has either an API or is basic enough to simply pull Data from the database? I really only need the software for managing, I plan to display all the posts programatically through MVC.

Recent Ubuntu update prevents MySQL root access

- by Rhys

I recently updated my Ubuntu (10.04 LTS) server (apt-get update, apt-get upgrade), and everything works fine, apart from the root access to my MySQL database. phpMyAdmin, CakePHP, and essentially all connections return similar access errors. For example, PMA returns 'Connection for controluser as defined in your configuration failed.' I have tried to find similar examples of this instance, but cannot find assistance in what configuration I should be changing to restore root log in access. The same issue has occurred on two servers. One has additional users so I could get around it, but the other is a new development server with only root MySQL access, so I am stuck on how to resolve this.

What is 'Ubuntu Unity' (for the Desktop)?

- by Martin

Ok, so there's the buzz of Canonical (wanting to) switch for new Ubuntu version from the GNOME default desktop to their own Unity shell. (I hope that's accurate.) It seems I can not totally fathom what Unity actually is. For looking at its homepage it currently is firmly targeted at netbooks and the somehow different usage model on these. Is it a classical desktop? -- Taskbar? Shortcuts? Is the difference between Ubuntu(GNOME)+Unity more/less pronounced than the difference between Ubuntu and Kubuntu? Will "my parents" be able to get the interface if they've been using the classical gnome desktop so far? Edit: I would not like to split this up into more specific questions, as What is Unity? is exactly what the people I set up Ubuntu boxes for will ask me if they hear that the newer Ubuntu version is using that instead of the Desktop -- and it might well happen someone phrases it like that :-) I will certainly not give them the link to the HP as the explanation there does not lay out if it is a desktop or something more or something less: (It does not for me - therefore I'm asking here.) Unity is designed for netbooks and related touch-based devices. It includes [...] that makes it fast and easy to access [...] while removing screen elements that are rarely used in mobile and netbook computing. (emphasis mine) -- the explanation there doesn't even mention the desktop-PC! Unity has a vertical task management panel on the left-hand side and a menu panel at the top of the screen. [...] This sounds like a re-themed normal desktop. Clicking on an icon will give the target application focus if it is already running or launch it if it is not already running. If you click the ... Aha. Sounds like Windows 7. ... icon of an application that already has focus, Unity will activate an Expose-style view of all the open windows associated with that application. No clue what that's supposed to be. So it would really be nice if someone could explain for non desktop-design-terms experts what Unity is.

ZFS for Database Log Files

- by user12620111

I've been troubled by drop outs in CPU usage in my application server, characterized by the CPUs suddenly going from close to 90% CPU busy to almost completely CPU idle for a few seconds. Here is an example of a drop out as shown by a snippet of vmstat data taken while the application server is under a heavy workload. # vmstat 1 kthr memory page disk faults cpu r b w swap free re mf pi po fr de sr s3 s4 s5 s6 in sy cs us sy id 1 0 0 130160176 116381952 0 16 0 0 0 0 0 0 0 0 0 207377 117715 203884 70 21 9 12 0 0 130160160 116381936 0 25 0 0 0 0 0 0 0 0 0 200413 117162 197250 70 20 9 11 0 0 130160176 116381920 0 16 0 0 0 0 0 0 1 0 0 203150 119365 200249 72 21 7 8 0 0 130160176 116377808 0 19 0 0 0 0 0 0 0 0 0 169826 96144 165194 56 17 27 0 0 0 130160176 116377800 0 16 0 0 0 0 0 0 0 0 1 10245 9376 9164 2 1 97 0 0 0 130160176 116377792 0 16 0 0 0 0 0 0 0 0 2 15742 12401 14784 4 1 95 0 0 0 130160176 116377776 2 16 0 0 0 0 0 0 1 0 0 19972 17703 19612 6 2 92 14 0 0 130160176 116377696 0 16 0 0 0 0 0 0 0 0 0 202794 116793 199807 71 21 8 9 0 0 130160160 116373584 0 30 0 0 0 0 0 0 18 0 0 203123 117857 198825 69 20 11 This behavior occurred consistently while the application server was processing synthetic transactions: HTTP requests from JMeter running on an external machine. I explored many theories trying to explain the drop outs, including: Unexpected JMeter behavior Network contention Java Garbage Collection Application Server thread pool problems Connection pool problems Database transaction processing Database I/O contention Graphing the CPU %idle led to a breakthrough: Several of the drop outs were 30 seconds apart. With that insight, I went digging through the data again and looking for other outliers that were 30 seconds apart. In the database server statistics, I found spikes in the iostat "asvc_t" (average response time of disk transactions, in milliseconds) for the disk drive that was being used for the database log files. Here is an example: extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 2053.6 0.0 8234.3 0.0 0.2 0.0 0.1 0 24 c3t60080E5...F4F6d0s0 0.0 2162.2 0.0 8652.8 0.0 0.3 0.0 0.1 0 28 c3t60080E5...F4F6d0s0 0.0 1102.5 0.0 10012.8 0.0 4.5 0.0 4.1 0 69 c3t60080E5...F4F6d0s0 0.0 74.0 0.0 7920.6 0.0 10.0 0.0 135.1 0 100 c3t60080E5...F4F6d0s0 0.0 568.7 0.0 6674.0 0.0 6.4 0.0 11.2 0 90 c3t60080E5...F4F6d0s0 0.0 1358.0 0.0 5456.0 0.0 0.6 0.0 0.4 0 55 c3t60080E5...F4F6d0s0 0.0 1314.3 0.0 5285.2 0.0 0.7 0.0 0.5 0 70 c3t60080E5...F4F6d0s0 Here is a little more information about my database configuration: The database and application server were running on two different SPARC servers. Storage for the database was on a storage array connected via 8 gigabit Fibre Channel Data storage and log file were on different physical disk drives Reliable low latency I/O is provided by battery backed NVRAM Highly available: Two Fibre Channel links accessed via MPxIO Two Mirrored cache controllers The log file physical disks were mirrored in the storage device Database log files on a ZFS Filesystem with cutting-edge technologies, such as copy-on-write and end-to-end checksumming Why would I be getting service time spikes in my high-end storage? First, I wanted to verify that the database log disk service time spikes aligned with the application server CPU drop outs, and they did: At first, I guessed that the disk service time spikes might be related to flushing the write through cache on the storage device, but I was unable to validate that theory. After searching the WWW for a while, I decided to try using a separate log device: # zpool add ZFS-db-41 log c3t60080E500017D55C000015C150A9F8A7d0 The ZFS log device is configured in a similar manner as described above: two physical disks mirrored in the storage array. This change to the database storage configuration eliminated the application server CPU drop outs: Here is the zpool configuration: # zpool status ZFS-db-41 pool: ZFS-db-41 state: ONLINE scan: none requested config: NAME STATE ZFS-db-41 ONLINE c3t60080E5...F4F6d0 ONLINE logs c3t60080E5...F8A7d0 ONLINE Now, the I/O spikes look like this: extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1053.5 0.0 4234.1 0.0 0.8 0.0 0.7 0 75 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1131.8 0.0 4555.3 0.0 0.8 0.0 0.7 0 76 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1167.6 0.0 4682.2 0.0 0.7 0.0 0.6 0 74 c3t60080E5...F8A7d0s0 0.0 162.2 0.0 19153.9 0.0 0.7 0.0 4.2 0 12 c3t60080E5...F4F6d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1247.2 0.0 4992.6 0.0 0.7 0.0 0.6 0 71 c3t60080E5...F8A7d0s0 0.0 41.0 0.0 70.0 0.0 0.1 0.0 1.6 0 2 c3t60080E5...F4F6d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1241.3 0.0 4989.3 0.0 0.8 0.0 0.6 0 75 c3t60080E5...F8A7d0s0 extended device statistics r/s w/s kr/s kw/s wait actv wsvc_t asvc_t %w %b device 0.0 1193.2 0.0 4772.9 0.0 0.7 0.0 0.6 0 71 c3t60080E5...F8A7d0s0 We can see the steady flow of 4k writes to the ZIL device from O_SYNC database log file writes. The spikes are from flushing the transaction group. Like almost all problems that I run into, once I thoroughly understand the problem, I find that other people have documented similar experiences. Thanks to all of you who have documented alternative approaches. Saved for another day: now that the problem is obvious, I should try "zfs:zfs_immediate_write_sz" as recommended in the ZFS Evil Tuning Guide.

Strange sound issues with Ubuntu 11.10

- by DNA

I am having strange issues with sound and volume with Ubuntu 11.10 I've noticed very often, especially when I get my computer out of sleep, it lacks sound even though the volume slider is cranked all the way up. But when I plug my headphones in and then take them out, it seems to kick start my sound back! What gives? What daemon in /etc/int.d needs to be restared with the restart command to fix this? I have the following in my init.d folder /etc/init.d/alsa-restore and /etc/init.d/alsa-store Also, my start up ubuntu sound doesn't play either....

How do I organize a GUI application for passing around events and for setting up reads from a shared resource

- by Savanni D'Gerinel

My tools involved here are GTK and Haskell. My questions are probably pretty trivial for anyone who has done significant GUI work, but I've been off in the equivalent of CGI applications for my whole career. I'm building an application that displays tabular data, displays the same data in a graph form, and has an edit field for both entering new data and for editing existing data. After asking about sharing resources, I decided that all of the data involved will be stored in an MVar so that every component can just read the current state from the MVar. All of that works, but now it is time for me to rearrange the application so that it can be interactive. With that in mind, I have three widgets: a TextView (for editing), a TreeView (for displaying the data), and a DrawingArea (for displaying the data as a graph). I THINK I need to do two things, and the core of my question is, are these the right things, or is there a better way. Thing the first: All event handlers, those functions that will be called any time a redisplay is needed, need to be written at a high level and then passed into the function that actually constructs the widget to begin with. For instance: drawStatData :: DrawingArea -> MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO () createStatView :: (DrawingArea -> IO ()) -> IO VBox createUI :: MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO HBox createUI storeMVar field = do graphs <- createStatView (\area -> drawStatData area storeMVar field) hbox <- hBoxNew False 10 boxPackStart hbox graphs PackNatural 0 return hbox In this case, createStatView builds up a VBox that contains a DrawingArea to graph the data and potentially other widgets. It attaches drawStatData to the realize and exposeEvent events for the DrawingArea. I would do something similar for the TreeView, but I am not completely sure what since I have not yet done it and what I am thinking of would involve replacing the TreeModel every time the TreeView needs to be updated. My alternative to the above would be... drawStatData :: DrawingArea -> MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO () createStatView :: IO (VBox, DrawingArea) ... but in this case, I would arrange createUI like so: createUI :: MVar Core.ST -> (Core.ST -> SetRepWorkout.WorkoutStore) -> IO HBox createUI storeMVar field = do (graphbox, graph) <- createStatView (\area -> drawStatData area storeMVar field) hbox <- hBoxNew False 10 boxPackStart hbox graphs PackNatural 0 on graph realize (drawStatData graph storeMVar field) on graph exposeEvent (do liftIO $ drawStatData graph storeMVar field return ()) return hbox I'm not sure which is better, but that does lead me to... Thing the second: it will be necessary for me to rig up an event system so that various events can send signals all the way to my widgets. I'm going to need a mediator of some kind to pass events around and to translate application-semantic events to the actual events that my widgets respond to. Is it better for me to pass my addressable widgets up the call stack to the level where the mediator lives, or to pass the mediator down the call stack and have the widgets register directly with it? So, in summary, my two questions: 1) pass widgets up the call stack to a global mediator, or pass the global mediator down and have the widgets register themselves to it? 2) pass my redraw functions to the builders and have the builders attach the redraw functions to the constructed widgets, or pass the constructed widgets back and have a higher level attach the redraw functions (and potentially link some widgets together)? Okay, and... 3) Books or wikis about GUI application architecture, preferably coherent architectures where people aren't arguing about minute details? The application in its current form (displays data but does not write data or allow for much interaction) is available at https://bitbucket.org/savannidgerinel/fitness . You can run the application by going to the root directory and typing runhaskell -isrc src/Main.hs data/ or... cabal build dist/build/fitness/fitness data/ You may need to install libraries, but cabal should tell you which ones.

Is code like this a "train wreck" (in violation of Law of Demeter)?

- by Michael Kjörling

Browsing through some code I've written, I came across the following construct which got me thinking. At a first glance, it seems clean enough. Yes, in the actual code the getLocation() method has a slightly more specific name which better describes exactly which location it gets. service.setLocation(this.configuration.getLocation().toString()); In this case, service is an instance variable of a known type, declared within the method. this.configuration comes from being passed in to the class constructor, and is an instance of a class implementing a specific interface (which mandates a public getLocation() method). Hence, the return type of the expression this.configuration.getLocation() is known; specifically in this case, it is a java.net.URL, whereas service.setLocation() wants a String. Since the two types String and URL are not directly compatible, some sort of conversion is required to fit the square peg in the round hole. However, according to the Law of Demeter as cited in Clean Code, a method f in class C should only call methods on C, objects created by or passed as arguments to f, and objects held in instance variables of C. Anything beyond that (the final toString() in my particular case above, unless you consider a temporary object created as a result of the method invocation itself, in which case the whole Law seems to be moot) is disallowed. Is there a valid reasoning why a call like the above, given the constraints listed, should be discouraged or even disallowed? Or am I just being overly nitpicky? If I were to implement a method URLToString() which simply calls toString() on a URL object (such as that returned by getLocation()) passed to it as a parameter, and returns the result, I could wrap the getLocation() call in it to achieve exactly the same result; effectively, I would just move the conversion one step outward. Would that somehow make it acceptable? (It seems to me, intuitively, that it should not make any difference either way, since all that does is move things around a little. However, going by the letter of the Law of Demeter as cited, it would be acceptable, since I would then be operating directly on a parameter to a function.) Would it make any difference if this was about something slightly more exotic than calling toString() on a standard type? When answering, do keep in mind that altering the behavior or API of the type that the service variable is of is not practical. Also, for the sake of argument, let's say that altering the return type of getLocation() is also impractical.

How important, if at all, is what school you go to towards your job prospects coming out of college? That is, how much difference is there between how a graduate of MIT/Stanford/etc treated vs RIT vs Monroe Community College vs Joe's Discount Diploma shop? I'm asking specifically outside of the education itself, and more towards the perceived value of your degree to prospective employers. What do you think?

Which physics phenomenons can be simulated properly with Box2d or bullet physics? [on hold]

- by user3585425

Knowing that box2d or bullet physics can't simulate Newton's cradle (because of multiple bodies being in contact at the same time if I understand correctly), is there a sets of physics phenomenons that imply two or more objects that still can be simulated properly ? For example, I'm thinking about lightweight objects launched towards heavyweight objects. If the object is destroyed on contact, this would not make a difference if the energy is not transmitted correctly on impact.

How can I deal with actor translations and other "noise" in third-party motion capture data?

- by Charles

I'm working on a game, and I've run into a problem with motion capture data. My team is using 3DS Max 2011 and trying to put free motion capture files on our models. The problem we're having is it has become extremely hard to find motion capture data that stays in place. We've found some great motion captures of things like walking and jumping but the actors themselves move within the data, so when we attach these animations to our models and bring them into XNA, the models walk forward even when they should technically be standing still (and then there's also the problem of them resetting at the end of the animation). How can we clean up, at runtime or asset-processing time, the animation in these motion capture files?

Internet connection problems can be frustrating. Rather than mashing F5 and desperately trying to reload your favorite website when you experience a problem, here are some ways you can troubleshoot the problem and identify the cause. Ensure you check the physical connections before getting too involved with troubleshooting. Someone could have accidentally kicked the router or modem’s power cable or pulled an Ethernet cable out of a socket, causing the problem.

Training v. Teaching

- by Chris Gardner

Originally posted on: http://geekswithblogs.net/freestylecoding/archive/2014/05/28/training-v.-teaching.aspxAs some of you may know, I recently accepted a position to teach an undergraduate course at my alma mater. Yesterday, I had my first day in an academic classroom. I immediately noticed a difference with the interactions between the students. They don't act like students in a professional training or conference talk. I wanted to use this opportunity to enumerate some of those differences. The immediate thing I noticed was the lack of open environment. This is not to say the class was hostile towards me. I am used to entering the room, bantering with audience, loosening everyone a bit, and flowing into the discussion. A purely academic audience does not banter. At least, they do not banter on day one. I think I can attribute this to two factors. This first is a greater perception of authority. In a training or conference environment, I am an equal with the audience. This is true even if I am being a subject matter expert. We're all professionals. We're all there to learn from each other, share our stories, and enjoy the journey. In the academic classroom, there was a distinct class difference. I had forgotten about this distinction; I had the professional familiarity with the staff by the time I completed my masters. This leads to the other distinction. These was an expectation of performance. At conference and professional training, there is generally no (immediate) grading. This may be a preparation for a certification exam, but I'm not the one responsible for delivering the exam. This was not the case in the academic classroom. These students are battling for points, and I am the sole arbiter. These students are less likely to let the material wash over them, applying the material to their past experiences. They were down taking notes. I don't want to leave the impression that there was no interact in the classroom. I spent a good deal of time doing problems with the class on the whiteboard. I tried to get the class to help me work out the steps. This opened up a few of them. After every conference or training class, I always get a few people that will email me afterward to continue the conversation. I am very curious to see if anybody comes to my office hours tomorrow. However, that is a curiosity that will have to wait until tomorrow.

How do I maintain a really poorly written code base?

- by onlineapplab.com

Recently I got hired to work on existing web application because of NDA I'm not at liberty to disclose any details but this application is working online in sort of a beta testing stage before official launch. We have a few hundred users right now but this number is supposed to significantly increase after official launch. The application is written in PHP (but it is irrelevant to my question) and is running on a dual xeon processor standalone server with severe performance problems. I have seen a lot of bad PHP code but this really sets new standards, especially knowing how much time and money was invested in developing it. it is as badly coded as possible there is PHP, HTML, SQL mixed together and code is repeated whenever it is necessary (especially SQL queries). there are not any functions used, not mentioning any OOP there are four versions of the app (desktop, iPhone, Android + other mobile) each version has pretty much the same functionality but was created by copying the whole code base, so now there are some differences between each version and it is really hard to maintain the database is really badly designed, which is causing severe performance problems also for fixing some errors in PHP code there is a lot of database triggers used which are updating data on SELECT and on INSERT so any testing is a nightmare Basically, any sin of a bad programming you can imagine is there for example it is not only possible to use SQL injections in literally every place but you can log into app if you use a login which doesn't exist and an empty password. The team which created this app is not working on it any more and there is an outsourced team which suggested that there are some problems but was never willing to deal with the elephant in the room partially because they've got a very comfortable contract and partially due to lack of skills (just my opinion). My job was supposed to be fixing some performance problems and extending existing functionality but first thing I was asked to do was a review of the existing code base. I've made my review and it was quite a shock for the management but my conclusions were after some time finally confirmed by other programmers. Management made it clear that it is not possible to start rewriting this app from scratch (which in my opinion should be done). We have to maintain its operable state and at the same time fix performance errors and extend the functionality. My question is, as I don't want just to patch the existing code, how to transform this into properly written app while keeping the existing code working at the same time? My plan is: Unify four existing versions into common code base (fixing only most obvious errors). Redesign db and use triggers to populate it with data (so data will be maintained in two formats at the same time) All new functionality will be written as separate project. Step by step transfer existing functionality into the new project After some time everything will be in the new project Some explanation about #2, right now it is practically impossible to make any updates in existing db any change requires reviewing whole code and making changes in many places. Is such plan feasible at all? Another solution is to walk away and leave the headache to someone else.

Good way to manage blog/news? [closed]

I really don't want to undertake handling blog/news posts within a site I'm working on and would much rather use some other software that's fairly bare-bones that will manage the posts and then I can just pull posts from the DB or an API. Does anyone have any experience with a nice, lightweight OS Blog type software that has either an API or is basic enough to simply pull Data from the database? I really only need the software for managing, I plan to display all the posts programatically through MVC.

Ubuntu App Submission won't allow the "free" bubble to be checked

- by Compt

I am at the final stages of the Ubuntu App Developer Showdown, and I'm right at the point where I am submitting my app. The problem I run in to however, is that even though buy is at $0.00, it will not allow me to click on the "free" button, and keep that configuration saved. So when I go to "preview your app", it shows it saying "USD $0.00 ---- Buy" instead of saying "Free ---- Install". So I was wondering if it makes any difference or not.

Fail to start windows after Ubuntu 11.10 install

- by user49995

Computer: HP Pavilion dv7-6140eo OS: Originally Win7 I recently decided to try out Ubuntu, and I decided to dual-boot it with Windows 7. First I googled some how-to's, then I downloaded Ubuntu onto a memory stick and made a second partition (I originally only had one partition that I shrunk and used the unallocated space to install onto during the Ubuntu install). During the install I set format type to xt4 (or something, it was the default option), chose the "in the beginning" option and set the last option as "\". The install was successful. Although, when I restarted my computer I weren't able to choose which operating system to start; it went right into windows. After showing the windows logo for half a second before rebooting, I get a blue screen (see bottom of the page). Trying to fix it, I deleted the newly made partition I had just installed Ubuntu onto (seeing it wasn't working either). This made no difference. I proceeded with installing Ubuntu again, so I would at least have a functioning computer, and now Ubuntu works fine (on it now). The only difference on start-up is that I get a Grub window asking me to between several options including Linux and Windows 7 (loader). Now, if I choose Windows 7, I get the message "Windows was unable to start. A recent software or hardware change might be the cause". It recommends me to choose the first option of the two it provides; to start start-up repair tool. The second option being starting windows normally. If I start windows normally, the same thing happens as earlier. My computer does not have a windows installation CD. Although, it has (at least it used to, if I haven't screwed that too up) a 17gb recovery partition. In addition I made an image of the computer onto a external hard drive when I first got it. Though, I have no idea how to use either. If anyone has any idea how I can make windows work again or reinstall it (already backed up my files) it would be greatly appreciated. I still prefer to dual boot between the two functioning operating systems, but I will settle for a functioning windows 7. Thanks a lot for any replies. Blue screen: A problem has been detected and Windows has been shut down to prevent damage to your computer. If this is the first time you've seen this Stop error screen, restart your computer.

Box2D platformer movement. Are joints a good idea?

- by Romeo

So i smashed my brains trying to make my character move. As i wanted later in the game to add explosions and bullets it wasn't a good idea to mess with the velocity and the forces/impulses didn't work as i expected so something stuck in my mind: Is it a good idea to put at his bottom a wheel(circle) which is invisible to the player that will do the movement by rotation? I will attach this to my main body with a revolute joint but i don't really know how to make the main body and wheel body to don't collide one with each other since funny things can happen. What is your oppinion?

Ubuntu missing from hard drive boot

- by Eoghan

Ubuntu is the only OS installed on my Acer netbook. Few, if any, problems until, with no warning, it vanished from the boot list for the hard drive. I have been a ble to create a bootable USB to be ablee to use the netbook but have not been able to restore Ubuntu to the hard drive boot list. As you can probabaly tell from the way the problem is described, I am a complete novice so any help you can give should assume no knowledge at all on my part and should be written as if for a simpleton. Thank you.
