  • How to provide value?

    - by Francisco Garcia
    Before I became a consultant all I cared about was becoming a highly skilled programmer. Now I believe that what my clients need is not a great hacker, coder, architect... or whatever. I am more and more convinced every day that there is something of greater value. Everywhere I go I discover practices where I used to roll my eyes in despair. I saw the software industry with pink glasses and laughed or cried at them depending on my mood. I was so convinced everything could be done better. Now I believe that what my clients desperately need is finding a balance between good engineering practices and desperate project execution. Although a great design can make a project cheap to maintain thought many years, usually it is more important to produce quick fast and cheap, just to see if the project can succeed. Before that, it does not really matters that much if the design is cheap to maintain, after that, it might be too late to improve things. They need people who get involved, who do some clandestine improvements into the project without their manager approval/consent/knowledge... because they are never given time for some tasks we all know are important. Not all good things can be done, some of them must come out of freewill, and some of them must be discussed in order to educate colleagues, managers, clients and ourselves. Now my big question is. What exactly are the skills and practices aside from great coding that can provide real value to the economical success of software projects? (and not the software architecture alone)

  • Read-only lock on a SharePoint site collection, or Why can't I edit anymore?

    - by PeterBrunone
    Monday morning, the calls started.  For some reason, long-time users were unable to edit list items.  I figured we had a permissions issue, so I popped in to look at the Site Settings -- and found that I couldn't.  A quick trip to Central Administration showed that I was still listed as a Site Collection Administrator, but I had no power at all on the site collection in question.A quick glance at the logs told me that the server had recently shut down unexpectedly (this is a Hyper-V virtual machine).  Apparently, in the confusion, somehow SharePoint decided to lock the site collection as Read Only.  This can be remedied in one of two ways:1)  In Central Administration, go to Application Management->SharePoint Site Management->Site collection quotas and locks.  Once you have arrived, select the correct application and site collection, and you will have the opportunity to view and set the lock status of the collection (it most likely will be set to "Read-only", and you'll want to move that radio button to "Not locked").2)  Fire up stsadm and issue the following command:stsadm -o setsitelock -url http://myportalsitecollection -lock none

  • Find points whose pairwise distances approximate a given distance matrix

    - by Stephan Kolassa
    Problem. I have a symmetric distance matrix with entries between zero and one, like this one: D = ( 0.0 0.4 0.0 0.5 ) ( 0.4 0.0 0.2 1.0 ) ( 0.0 0.2 0.0 0.7 ) ( 0.5 1.0 0.7 0.0 ) I would like to find points in the plane that have (approximately) the pairwise distances given in D. I understand that this will usually not be possible with strictly correct distances, so I would be happy with a "good" approximation. My matrices are smallish, no more than 10x10, so performance is not an issue. Question. Does anyone know of an algorithm to do this? Background. I have sets of probability densities between which I calculate Hellinger distances, which I would like to visualize as above. Each set contains no more than 10 densities (see above), but I have a couple of hundred sets. What I did so far. I did consider posting at math.SE, but looking at what gets tagged as "geometry" there, it seems like this kind of computational geometry question would be more on-topic here. If the community thinks this should be migrated, please go ahead. This looks like a straightforward problem in computational geometry, and I would assume that anyone involved in clustering might be interested in such a visualization, but I haven't been able to google anything. One simple approach would be to randomly plonk down points and perturb them until the distance matrix is close to D, e.g., using Simulated Annealing, or run a Genetic Algorithm. I have to admit that I haven't tried that yet, hoping for a smarter way. One specific operationalization of a "good" approximation in the sense above is Problem 4 in the Open Problems section here, with k=2. Now, while finding an algorithm that is guaranteed to find the minimum l1-distance between D and the resulting distance matrix may be an open question, it still seems possible that there at least is some approximation to this optimal solution. If I don't get an answer here, I'll mail the gentleman who posed that problem and ask whether he knows of any approximation algorithm (and post any answer I get to that here).

  • Coda-like experience for Ubuntu

    - by Dillon Gilmore
    I'm a web developer who's going to transition from using Mac OS X to Ubuntu. I've been using Coda for some time, only because it makes web development easy. I know a full fledged app isn't available for Linux, but would like to know about apps that specialize in the same tasks that Coda offers. I plan on switching to Vim for code editing, I'm extremely proficient and will install the Janus plugin and be good to go for editing code. One thing that makes editing on Coda so amazing is its extremely good at SFTP, you can drag and drop files and/or folders from your local drive to the server. Also, you can edit code directly on the server. The problem here, is that using Vim I don't know of a way to edit code on a remote server, while using my own Vim settings and plugins. To solve this, I would like to know of a good SFTP client OR a good SFTP CLI. A CLI that could synchronize your files after a file has been modified would be perfect, but not necessary. Now, one of the biggest and best features of Coda is its ability to view your databases. You get to create a database, create tables, add stuff, delete stuff and view the contents of the table (all this without writing a single SQL statement). I will admit that databases are my weak point, but is a very important part of my job. If there is a tool that specializes in databases would be perfect. I wouldn't prefer to use the command line for database stuff, but if there is a CLI for databases that I'm missing could potentially be useful. So I guess I'm asking for two things. A tool that makes databases easier to visualize and a tool that assists in pushing my local code to a server.

  • Build & Install Ruby Gems with Rake

    - by kerry
    Are you using rake to build your gems?  Have you ever wished there were an install task to install it to your machine?  I, for one, have written something like this a few times: 1: desc 'Install the gem' 2: task :install do 3: exec 'gem install pkg/goodies-0.1.gem' 4: end 5:  That is pretty straightforward.  However, this will not work under JRuby on Mac where the command should be ‘jgem’.  So we can enhance it to detect the platform, and host OS: 1: desc 'Install the gem' 2: task :install do 3: executable = RUBY_PLATFORM[/java/] && Config::CONFIG[/darwin/] ? 'jgem' : 'gem' 4: exec "#{executable} install pkg/goodies-0.1.gem" 5: end This is a little better.  I am still not comfortable with the sloppiness of building a shell command and executing it though.  It is possible to do it with strictly Ruby.  I am also going namespace it to integrate better with the GemPackageTask.  Now it will be accessed via ‘rake gem:install’ 1: desc 'Install the gem' 2: namespace 'gem' do 3: task :install do 4: Gem::Installer.new('pkg/goodies-0.1.gem').install 5: end 6: end   I have included this in the goodies gem 0.2, so go ahead and install it!  ‘gem install goodies’

  • grub workaround for cannot find UUID in dual boot system fails and now grub won't boot anything

    - by keepitsimpleengineer
    New clean install of x86 11.10 desktop. Dual boot with windows XP and Linux on separate drives. After install grub will not boot Windows, but by changing boot drive boots fine. When I go to fix this I find from http://bootinfoscript.sourceforge.net/ and a link to http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:search my problem, the message on the grub boot error screen: error: no such device: 6??????? So I follow the Step2 and compare the output of: sudo blkid and sudo nano /boot/grub/grub.cfg The UUIDs in both match for the Windows drive, so I do the fix in Step 4 "remove the search lines for …" in /usr/lib/grub/grub-mkconfig_lib, commenting out the three lines as before? # if fs_uuid="`${grub_probe} --device ${device} --target=fs_uuid 2> /dev/null`" ; then # echo "search --no-floppy --fs-uuid --set ${fs_uuid}" # fi I run sudo update-grub and check /etc/default/grub.cfg and see that it now identifies the Windows partition not by UUID, which I suppose is the workaround. But now when I try to boot 11.10 Desktop, I get: error: no such partition… … and when I try to boot Windows, I get: error: invalid signature. So Now, how do I fix this… The boot problem and find a workaround that works?

  • Best way to implement mouse-based movement in MMOG

    - by fiftyeight
    I want to design an MMO where players click the destination they want to walk to with their mouse and the character moves there, similar to Runescape in this manner. I think it should be easier than keyboard movement since the client can simply send the server the destination each time the player clicks on a destination. The main thing I'm trying to decide is what to do when there are obstacles in the way. It's no problem to implement a simple path-finding solution on the client, the question is if the server will do path-finding as well, since it'll probably take too much Computation power from the server. What I though is that when there is an obstacle the client will send only the first coordinate it plans to go to and then when he gets there he'll send the next coordinate automatically. For example if there is a rock in the way the character will decide on a route that is made of two destinations so it goes around the rock and when it arrives at the first destination it sends the next coordinate. That way if the player changes destination is the middle he won't send unnecessary information. Is this a good way to implement it and is there a standard way MMOGs usually do it? EDIT: I should also mention that the server will make sure all movements are legal and there aren't any walls in the way etc. In the way I wrote it should be quite easy since all movements will be sent in straight lines so the server will just check there aren't any obstacles along that line.

  • PeopleSoft 8.52 iPad Certification

    - by Dave Bain
    One of the real gems in the PeopleTools 8.52 release is the certification of PeopleSoft applications running in the Safari Browser on an iPad.  It is nice that PeopleSoft is not constrained by technology like Adobe Flex/Flash, so announcements like this "Adobe drops plans for mobile Flash support" do not limit our mobile solution to custom mobile development. There are parts of PeopleSoft applications that operate better on iPads than others.  One of the best is Workcenters.  Workcenters were new to PeopleTools 8.51 and we are starting to see more and more adoption of them.  Workcenters are roll based landing pages that eliminate difficult navigation by providing access to most links, pages, and reports a user in a role needs.  One of the nicest I’ve seen is the Supply Manager Workspace.  Here are some links to screenshots of what a WorkCenter looks like on an iPad: Here's the standard PeopleSoft Login Page The Supply Manager Workspace looks great full screen on an iPad iPad has a great user interface to zoom, here's a screenshot of an upclose view of an analytic. Touch one of the analytics and it drills into the details. Go ahead and give it a try.  WorkCenters and Dashboards are starting to show up across applications.  For a quick one to try, navigate to the PeopleTools->Integration Broker->Integration Network WorkCenter.  It’s new in PeopleTools 8.52.

  • Using Behavior Trees and Events together

    - by weichsem
    I am beginning to work with behavior trees and am unsure how events should be handled within the tree. Lets say we have a space game where the player is dogfighting with a handful of other ships, some friendly some not. The player destroys a ship and the rest of the hostile ships should then start to retreat. How was should the shipWasDestroyed event effect the other ship's behavior trees so that they start running the retreat behavior? One way I could think of doing this is have all the conditions I care about be high level nodes that effectively state change the ship. This would mean I'd have to check all of these state change conditions on every frame the behavior tree was run, even if they are very rare occurrences. I'd prefer not doing this for performance and complexity reasons. From looking at the Halo papers on behavior trees it seems that they handled this by dynamically placing nodes into the tree when the event occurred. It seems like calculating where the new node should go could be problematic depending on the current state of the running behavior. How is this normally handled?

  • Need help with exploring a USB drive

    - by Bob Getsla
    When I plug in a USB drive, I see it on the left hand edge of the Unity desktop (11.10, 64 bit) but when I try to explore it, VLC starts and tries to play whatever it can find in the USB drive. This behavior began when I updated from 11.04 to 11.10. I literally cannot look into the contents of any of the USB drives I have, because I cannot stop VLC, nor can I do anything when I click Open other than watch VLC start up. This is very frustrating because it makes my USB sticks essentially useless. HELP! I'm sure that there is something a wizard could do about this, but I am not a wizard, and I am at my wits ends. Trying to get to the System Settings menu works, and I can see the setup for "Removable" devices, and they are all set to "Ask" but that is clearly not what is happening. So it looks like I must reach for the command line, but where do I go to find the settings for what the desktop does when I plug in a USB drive and wish to explore the file structure in it and possible copy a file into the USB or from the USB drive. Right now, VLC media player is always getting in my way. :-(

  • How can I set my resolution to 1280x1024 on an Acer Aspire Revo 3700?

    - by torbengb
    I've just set up a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. Almost everything works OK, but the graphics are not OK: the recommended Nvidia driver is activated but the monitor is not detected, so the resolution is wrong. How can I make Ubuntu detect my monitor? How can I get the proper resolution (1280x1024) in Ubuntu? I know that my monitor is not a CRT but an LCD: it's a BenQ, model T905, with 1280x1024 resolution at 60Hz, connected via a normal VGA cable. DVI or HDMI is not an option. When I go to SystemPrefsMonitors, I get: It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead? YES NO If I say NO then I get a window: or for YES I get this: In both cases I don't see that I can fix this problem. The main reason for getting this new computer was that I was sick of having graphics problems on the old one with a very ugly solution that didn't give me hardware support - but at least I got the resultion. Why is this so difficult... sigh!

  • Google affecting my SERP Rank?

    - by Asad Moeen
    The following are some of my website's details. Home-page: [thebluewaffles].[com] Keywords: Blue Waffles- Rest of the keywords are post/subject specific. Site Description: Health Articles Blog Site Age: 1.5 years A short history: When I started my website, the few things in my mind when posting content were at-least 500 words on each page and writing of all the articles with to the point information. I didn't go really fast with it which is why I only have about 15 articles in 1.5 years. The SEO strategy was more simple. I shared links through Social Marketing websites and some Article Sharing websites after which I could see my website's rankings in top 5 SERP results. I ranked good enough for about 8 months continuously but didn't keep updating content due to which there were some 3 rough months when no content was posted due to some personal work. The SERPS dropped to 2nd page in April and almost started disappearing in May. I asked a lot of people about it and most came up with the reason of "no updates to site" so I started updating my site again since the day, November has almost started and I see no signs of my website's ranking. Another important point is that when I post a new article, and do a title search in Google, I see it ranks good enough for the first 10 hours and then disappears. What could be wrong here?

  • C++ Iterator lifetime and detecting invalidation

    - by DK.
    Based on what's considered idiomatic in C++11: should an iterator into a custom container survive the container itself being destroyed? should it be possible to detect when an iterator becomes invalidated? are the above conditional on "debug builds" in practice? Details: I've recently been brushing up on my C++ and learning my way around C++11. As part of that, I've been writing an idiomatic wrapper around the uriparser library. Part of this is wrapping the linked list representation of parsed path components. I'm looking for advice on what's idiomatic for containers. One thing that worries me, coming most recently from garbage-collected languages, is ensuring that random objects don't just go disappearing on users if they make a mistake regarding lifetimes. To account for this, both the PathList container and its iterators keep a shared_ptr to the actual internal state object. This ensures that as long as anything pointing into that data exists, so does the data. However, looking at the STL (and lots of searching), it doesn't look like C++ containers guarantee this. I have this horrible suspicion that the expectation is to just let containers be destroyed, invalidating any iterators along with it. std::vector certainly seems to let iterators get invalidated and still (incorrectly) function. What I want to know is: what is expected from "good"/idiomatic C++11 code? Given the shiny new smart pointers, it seems kind of strange that STL allows you to easily blow your legs off by accidentally leaking an iterator. Is using shared_ptr to the backing data an unnecessary inefficiency, a good idea for debugging or something expected that STL just doesn't do? (I'm hoping that grounding this to "idiomatic C++11" avoids charges of subjectivity...)

  • Ensuring non conflicting components in a modular system

    - by Hailwood
    So lets say we are creating a simple "modular system" framework. The bare bones might be the user management. But we want things like the Page Manager, the Blog, the Image Gallery to all be "optional" components. So a developer could install the Page Manager to allow their client to add a static home page and about page with content they can easily edit with a wysiwyg editor. The developer could then also install the Blog component to allow the client to add blog entries. The developer could then also install the Gallery component to allow the client to show off a bunch of images. The thing is, all these components are designed to be independent, so how do we go about ensuring they don't clash? E.g. ensuring the client doesn't create a /gallery page with the Page Manager and then wonder why the gallery stopped working, or the same issue with the Blog component, assuming we allow the users to customize the URL structure of the blog (because remember, the Page Manager doesn't necessarily have to be there, so we might not wan't our blog posts to be Date/Title formatted), likewise our clients aren't always going to be happy to have their pages under pages/title formatting. My core question here is, when building a modular system how to we ensure that the modules don't conflict without restricting functionality? Do we just leave it up to the clients/developer using the modules to ensure they get setup in a way that does not conflict?

  • Copying photos from camera stalls - how to track down issue?

    - by Hamish Downer
    When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs). None of the programs at the top of the cpu list in top are related to copying photos. There is not much in the logs - from /var/log/syslog Dec 2 16:20:52 mishtop dbus[945]: [system] Activating service name='org.freedesktop.UDisks' (using servicehelper) Dec 2 16:20:52 mishtop dbus[945]: [system] Successfully activated service 'org.freedesktop.UDisks' Dec 2 16:21:24 mishtop kernel: [ 2297.180130] usb 2-2: new high-speed USB device number 4 using ehci_hcd Dec 2 16:21:24 mishtop kernel: [ 2297.314272] usb 2-2: New USB device found, idVendor=04a9, idProduct=3146 Dec 2 16:21:24 mishtop kernel: [ 2297.314278] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Dec 2 16:21:24 mishtop kernel: [ 2297.314283] usb 2-2: Product: Canon Digital Camera Dec 2 16:21:24 mishtop kernel: [ 2297.314287] usb 2-2: Manufacturer: Canon Inc.

  • Can't change settings for Mobile Broadband Dongle - Button is greyed out

    - by Ross LIndsey
    I was with VirginBroadband.com.au (Australia). My huawai 3G Dongle was working great on Ubuntu, However I have changed ISP's. I unlocked the modem, and put in the new SIM. I have tested this in my Windows PC and it connects to the new (Optus) Network A-OK and it all works. When I put this dongle (the same one that was working fine in Ubuntu) into that same Ubuntu Netbook it simply won't connect. When I try to go into the dialog to try and add or change settings the button to change or update settings is greyed out, I can't select it. Apparently since this dongle was already recognized the Broadband Setup Wizard won't start, and I have no idea how to get it to start (presuming it has the ability to configure an already recognized dongle). What do I have to do to either enable the ability to change the configuration for this setup, or to blow away the one that is set up so the Broadband Wizard will re-start and let me configure a new one. Can anyone provide simple instructions for doing this? I'm using Ubuntu with the Cinnamon Desktop

    I have been looking all over the web, and tried every suggestion I found to get the nvidia drivers working on my computer with Ubuntu Gnome 14.04, with no luck. Every time I install a driver or choose to use the driver from addition drivers, when I reebot, I cannot log in again. It gets stuck at the logo screen. I need to go to the ALT + CTRL + F1 to purge all nvidia traces so I can get back. Is it possible to install the new nvidia drivers? I just upgraded from 13.10 to 14.04, I have an Asus N550VJ which has hybrid graphics with Intel 4000 / Nvidia 750M What Im looking for is to try the primus functionality to disable the discreet card and enable it whenever I want to play or run heavy graphic stuff. When I was in 13.10 I was using bumblebee, but, since, the nvidia prime is supposedly mature enough, I wanted to try it. Is this possible for Ubuntu Gnome 14.04. I read there was a bug with gdm, but also, saw that it was already fixed. Thank you very much for your help. Im not that well versed in linux.

  • How to build Visual Studio Setup projects (.vdproj) with TFS 2010 Build ?

    - by Vishal
    Out of the box, Team Foundation Server 2010 Build does not support building of setup projects (.vdproj). Although, you can modify DefaultTemplate.xaml or create your own in order to achieve this. I had to try bunch of different blog post's and finally got it working with a mixture of all those posts.   Since you don’t have to go through this pain again, I have uploaded the Template which you can use right away : https://skydrive.live.com/redir?resid=65B2671F6B93CDE9!310 Download and CheckIn this template into your source control. Modify your Build Definition to use this template. Unless you have CheckedIn the template, it wont show up in the template selection section in the process task of build definition. In your Visual Studio Solution Configuration Manager, make sure you specify to build the setup project also. You might get this warning in your build result: “The project file “*.vdproj” is not support by MSBuild and cannot be build. Hope it helps. Thanks, Vishal Mody Reference blog posts I had used: http://geekswithblogs.net/jakob/archive/2010/05/14/building-visual-studio-setup-projects-with-tfs-2010-team-build.aspx http://donovanbrown.com/post/I-need-to-build-a-project-that-is-not-supported-by-MSBuild.aspx http://lajak.wordpress.com/2011/02/19/build-biztalk-deployment-framework-projects-using-tfs2010/

  • what is the best program to capture my workings as an AVI or MPEG

    - by raihanchy
    I have already used recordmydesktop, xvidcap and kazam. My sound working fine with other audio or videos. xvidcap doesn't record sound at all. I have tried many ways. If I try as: 'padsp xvidcap', it also gives error, like: /dev/dsp cannot found or missing. I have changed it to /dev/snd. Still no effect. Even I can record sound through gnome-sound-recorder - after pressing record button, I open pavucontrol. Then from Recording tab, I choose 'Monitor of Analog Stereo'. But if I run xvidcap, I don't get that option in pavucontrol. kazam works a bit slow. It records at the beginning of the captured video. But for unknown reason, it eventually the sounds just go off. Also the video is not smooth as xvidcap. Though Kazam output as H64/MP4. Record my Desktop also doesn't give sound. Can you guys please help me, either - how to get sound with xvidcap or how kazam could be record nicely. I am looking something Camtasia, as used for Windows. Thanks in advance. Raihan

  • How to reduce the fan noise and how to increase battery life in ubuntu 11.10/12.04?

    - by mehdi
    I have a brand new Sony Vaio S series laptop.(VPCSA2DGX) It came factory installed with Windows 7 professional Edition 64bit. Runs Intel core i5, 500 GB HDD , 4GB Ram. First I installed ubuntu 11.10 64 bit along side Windows to dual boot. Later,since the problem did not solve, I installed ubuntu 12.04 64bit along side Windows to dual boot. However the problem keeps annoying me. Problem: When running ubuntu 11.10/12.04, the battery lasts only about 1.5 hours. The Fan runs loud and continuously. And there is a lot of heat generated. System monitor shows less than 5% CPU used. My laptop enjoys hybrid graphic and I tried turning off ADM graphic card and keep Intel graphic card on. However I can not get the Fan noise or heat to go away and consequently the battery drain continues. BTW, in windows, the laptop gives 4-5 hours of battery power, Fan is silent and there is no heat problem. Any ideas on how to reduce the fan noise and how to increase battery life in ubuntu 11.10/12.04?
