• Black stripe appears to the right of the screen, impossible to get rid of

  - by Gabriele Cirulli

  After clicking the "Auto Config" button on my Acer AL2216w screen a stripe appeared on the right of the screen where the screen doesn't "exist" and I can't seem to take the screen viewport back even by using the OCD setting and moving it to the right. The left part of the screen is also hidden and I'm not able to see what's going on there. The PC is connected to the screen through a DVI adapter and a VGA cable. I also use multiple monitors and this is the second monitor. Anyway this seems not to be a related issue, as this used to happen even when I only had a single monitor. I managed to fix this issue once but it was more than two years ago and I can't remember what I did, and out of all of the things I've tried so far (connecting the screen to another PC and performing auto adjustment, switching the cables, etc.) none worked. Here's how it looks: Can anyone help me fix this?

• Why does my SQL Server use AWE memory? and why is this not visible in RAMMap?

  - by Marnix Klooster

  We have a Windows Server 2008 R2 (64-bit) 8GB server where, according to Sysinternals RAMMap, 2GB of memory is allocated using AWE. As far as I understood, this means that these pages stay in physical memory and are never pushed out. This causes other apps to be pushed out of physical memory. In RAMMap, on the Physical Pages tab, the Process column is empty for all of the AWE pages. We run SQL Server on that box, but (through SQL Server Management Studio, under Server Properties - Memory, under Server memory options) it says is configured not to use AWE. However, when stopping SQL Server, the AWE pages are suddenly gone. So it really is the culprit. So I have three questions: Why does RAMMap not know/show that a SQL Server process is responsible for that AWE memory? Why does SQL Server Management Studio say that AWE memory is not used? How do we make configure SQL Server to really not use AWE memory?

• IPsec Policy Agent flip-flopping demand start/auto start in Windows Server 2008?

  - by Steve Wortham

  Looking through the event logs on my web server I noticed a strange pattern. The following events have been occurring over and over again, always back to back: The start type of the IPsec Policy Agent service was changed from demand start to auto start. The start type of the IPsec Policy Agent service was changed from auto start to demand start. Each one produces event id 7040 from the Service Control Manager. And sometimes this will happen 20 times in one minute. Any idea what would cause this? I've been trying to pinpoint an intermittent performance problem for the past several days and this is the most peculiar thing I've found so far. I'm running Windows Server 2008, SQL Server 2008, and ASP.NET 3.5 w/ MVC 1.

• Email client supporting multiple accounts

  - by TGP1994

  I've been using Microsoft Outlook for a very long time, although one thing that has bugged me is how multiple email accounts are handled. As far as I can tell, there isn't a set and straightforward way of managing multiple accounts in one instance of outlook. For example, when I create an email, saving it as a draft will by default dump it into the first personal folder that I have open, which in my current case, is not where I want it. I would like all trash, spam, drafts, contacts, etc. etc. to be handled on a PF by PF basis. Now to my question: Is there a way to accomplish the task of email account "segregation" in Outlook (2007 is my current version), or is there another client that handles this in a more organized fashion? Note: I don't use most of the features in outlook (I hardly even need special formatting for my messages), I generally just send and read mail, and get a few attachments, so leaving Outlook wouldn't be too much of a stretch for me.

• ATI Driver for HP Pavilion dv2 notebook?

  - by Greg Mattes

  I'm looking for a Windows XP Professional (32-bit) ATI video driver for an HP Pavilion dv2 (model 1118nr). I've downloaded and run several drivers packages, but none have worked so far. The notebook has a sticker on it that reads, "ATI Radeon Premium Graphics 3000 Series" The notebook has an AMD Athlon Neo 64 CPU and it came with Vista 64, but I have a requirement to run 32-bit Windows XP. Does such a driver exist, and if so, where is it? I've tried the AMD ATI graphics drivers portal, but the "Mobility Radeon" section does not list the 3000 series. The "Radeon" section does list the 3000 series, but the package I downloaded and installed from there was not helpful. I also selected "All Graphics - Notebook" on the "Search Drivers and Downloads" page, then selected "Windows XP Professional/Home" on the OS drop down, pressed "Submit", and downloaded and installed the only choice (this single choice is listed twice), but again, it didn't seem to help.

• Gimpshop 2.8. Available for Win & Mac. No Linux version?

  - by Jorge M. Treviño

  Finally got around to upgrading 12.04 to 12.10. One of the nice things about the new version is that Gimp 2.8 is in the repositories. Installed and it's a far cry from the 2.2, 2.4 and 2.6 versions which were —at least from my untrained point of view– next to unusable. Now 2.8 is a much more intuitive, for Photoshop users at least, and I'm trying to really learn it. Browsing around, I found that there's s new version of Gimpshop, something that was a sorely amateurish attempt to a PS interface over an old Gimp version and sure to mess up your system. Seeing "2.8" prominently displayed in the page, I decided to try the Windows version. Oddly, there's a Mac version too but no Linux one. The link directs one to a non-existent file in one of the cloud storage sites. After the Win version was installed, I fired it up and, surprise!, it's exactly the same as I can tell without diving into menus and dialogs, as the plain vanilla Ubuntu version I have installed. Can anybody shed light on what goes on here? Is this a scheme to get inadvertent users to install some "optional extras" that come with the installer? Very curious about it (thanks God I'm not a cat ).

• How do I use a virtualbox guest machine as a gateway?

  - by Igor Zinov'yev

  I have a certain problem. I am working on an Ubuntu machine, but I have to use a windows 2003 server guest to connect to a Stonegate VPN to be able to manage our client's website. I have already asked if I could connect to a Stonegate VPN in Ubuntu, but so far got no answer. And I couldn't connect to it using network manager's strongswan plugin. So I want to use my guest Win2003 as a gateway to be able to SSH to the remote server. Is that possible? Thank you very much in advance, if this is possible in any way, it will save me a lot of trouble!

• Best way to indicate more results available

  - by Alex Stangl

  We have a service to return messages. We want to limit the number returned, either allowing the caller to specify the max number to return, or else to use an internal hard limit. We also have thought it would be nice to include in the response whether more messages are available. The "best" way to go about this is not clear. Here are some ideas so far: Only set the "more messages" indicator if the user did not specify a max limit, and the internal max limit was hit. Same as #1 except that "more messages" indicator set regardless of whether the internal hard limit is hit, or the user-specified limit is hit. Same as #1 (or #2) except that we internally read limit + 1 records, but only return limit records, so we know "for sure" there is at least one additional message rather than "maybe" there are additional messages. Do away with the "more messages" flag, as it is confusing and unnecessary. Instead force the user to keep calling the API until it returns no messages. Change "more messages" indicator to something more akin to an EOF indicator, only set when the last message is known to have been retrieved and returned. What do you think is the best solution? (Doesn't have to be one of the above choices.) I searched and couldn't find a similar question already asked. Hopefully this is not "too subjective".

• What is Ubuntu's Definition of a "Registered Application"?

  - by Tom

  I've run into this a few times when installing apps from source, and during the occasional hack with update-alternatives. So far, it's only been a minor annoyance (ie, not got in the way of the end-goal) but it's now a frustration as it's pointing to a hole in my knowledge-base... so when I get a message that 'foo' is "not a registered application" (or I can't use foo's default icon cuz Ubuntu has no knowledge of 'foo'): (1) what defines a "registered application"? (2) how can I define an application installed from source (and likely residing in $HOME/bin/app-name) such that it packs the same functionality as a package installed from a .deb? (if the solution is not self-evident from answer 1) Example: I download and unpack daily dev builds of sublime-text-2 to /home/tom/bin/sublime-text-2. I've created a *.desktop file with appropriate shortcuts, etc. But the icon for sublime cannot be display in any launcher even if I provide a full pathname to the option. The solution is to install a 2nd instance of sublime from a deb package. When I install sublime-text-2 from a .deb package, it installs under /usr/bin && /usr/lib, the installed .desktop file is stored under /usr/share/applications, and the relevant line reads: icon=sublime_text. Where's the linkage I'm missing? Somehow Ubuntu knows how to exact the icon from sublime_text in the latter, but not in the former (again, even with a full path provided).

• Choosing between PHP and Java

  - by user996459

  I've recently started University, studying Computing and IT. My Uni focuses on Java. My study will consist of mathematics, 'boring' IT related stuff and several Java units such as: -Software development with Java, -Object-oriented Java programming, -Relational databases: theory and practice (using Java), -Developing concurrent distributed systems (using Java), -Software engineering with objects (using Java). I'm trying to determine whenever I should focus on Java and self study it in my free time so that I can actually learn and become a competent Java programmer by the time I graduate, or, only do enough Java to get the degree but in my free time self study PHP and related web technologies. Job market in my area appears to be balanced for the two, salary and availability wise. Regardless of which patch I'd take getting a job should not be a problem however Java does seem to pay almost insignificantly more. In terms of my interest and career expectations, I don't have anything specific planned. I very much enjoy writing code but I don't really care what kind. So far I equally enjoyed writing C, AutoIT, vb.net, PHP and even Java. Basically, I'm happy as long as I get to type in code (be it low level programming or web back-end scripting). So the question really is, would my Uni and their Java focus profit me should I choose PHP? Or should I buy what my university is selling and stick to Java like a fly sticks to poop...? Apologies for cryptic writing, still learning English

• VirtualBox: Why are some USB devices disabled?

  - by torbengb

  Overview: My Host OS is Ubuntu 10.10 and guest OS is WinXP on the VirtualBox version downloaded from Oracle including "VirtualBox 4.0 Oracle VM VirtualBox Extension Pack" so that USB passthrough works. This works in general (I was able to back up my iPhone to iTunes in the guest OS), but some devices aren't available even though they're ptrovided in the VirtualBox settings. Specifics: In the VirtualBox settings for the guest OS, there's the part where you can select which of your USB devices should be visible to the guest OS. I've selected several devices including the iPhone. So far so good. Then an iOS upgrade came along; my iPhone is now in DFU mode (or recovery mode?) and represents itself not as "iPhone" but as "iPhone (DFU mode)". I have now also added this device to the list of USB devices that the guest OS should see -- but it doesn't see this device. Questions: Am I right in expecting that the guest OS ought to see the DFU device when I add it in the VirtualBox settings? What steps do I need to take so that the guest OS will really see the DFU device?

• Platformer Enemy AI

  - by hayer

  I'm currently developing a platformer shooter. The game is multiplayer and while my net code could use some real work I have put that off for the time, so currently I'm trying to implement the AI. The game is pretty simple; Players run around on a map filled with a X amount of zombies that try to eat their brains, classic and overused I know. Weapons spawn at random intervals around the map. The problem is that the zombies, when they find their pray the have to follow it for some while.. And here is the problem, running the AI navcode seems to take for ever. So here is the ideas I have come up with so far Have the AI update at different intervals with a maximum of Y ms with no updates. Have the zombies assigned to groups of zombies. One is appointed the leader of the group who finds the way to the player - the rest just follows the leader. If the leader dies another one of the zombies in the group is appointed president of the zombie swarm. If there is less than five zombies in a group they try to meet up with other zombies.(Aka they are assigned to a different group and therefor a new leader) Multi-threading option one or two? For navigation I have some kinda navmesh(since the game is not tile-based) that tells the zombies where they can walk etc. If anyone else got some ideas on how to do navigation I would love some input. For LoS(zombie - player) I have split the map into grids. If the players grid is connected to the zombies grid(if I go with option two I would only need to check if leader zombies grid is connected to player, aka less checks) - if they are connected and there is more than 250ms since last check do a raytrace.. This is my first time programming AI so input on any field is appreciated.

• Can not access Internet (DNS names do not resolve) after update today

  - by Aras

  I have been using Precise for a few weeks now for work with no problem. Today, I am not able to access any website using either wired or wireless connections. I installed the updates today which included nautilus, xserver, and a new kernel (3.2.0-24). After restarting I no longer was able to browse the Internet using firefox or chrome. Trying to ping google in terminal gives ping: unknown host google.ca I have tried: Connecting to wireless or wired networks (both working on other machines) Restart the machine and boot with previous Kernel Manually configure opendns on my wired connection Restart the network and the laptop and the wireless card Without any success so far. I am not sure where to go next. Please let me know the cause of the issue or help me troubleshoot it. Note that the laptop does receive an ip address, and it can ping ip address of google.ca (74.125.127.94) but not the domain name, or any domain name for that matter. This system was upgraded from 11.10 to 12.04 more two weeks ago.

• Linux - Scriptable email client?

  - by Phog

  Hi, I'm writing a simple UI for the visually impaired using a speech synthesizer. I've looked all over the internet for an email client which I can script to fit these purposes but to no avail. I believe several CLI email clients(eg MUTT) allow sending emails with command line arguments only. But I've yet to find a client that can download the emails, decode them and then dump them to a text file. The best candidate so far seems to be mailx, but it seems like it needs quite a lot of babysitting to fit my needs. Any suggestions for scripting-friendly email clients? Am I missing something fundamental about MUTT? Are there any libraries/programs that help me decode the MIME encoding used in todays emails from a maildir? Should I just bite the bullet and write a script for mailx? Thanks in advance.

• How to allow IAM users to setup their own virtual MFA devices

  - by Ali

  I want to let my IAM users to setup their own MFA devices, through the console, is there a single policy that I can use to achieve this? So far I can achieve this through a number of IAM policies, letting them list all mfa devices and list users (so that they can find themselves in the IAM console and ... I am basically looking for a more straight forward way of controlling this. I should add that my IAM users are trusted users, so I don't have to (although it will be quite nice) lock them down to the minimum possible, so if they can see a list of all users that is ok.

• Why is the size of antivirus greater than that of anti malware? [on hold]

  - by Mistu4u

  Recently my computer was attacked by different kinds of worms and my computer was slowed down. So I tried to remove them by installing Avast free antivirus. The worms were copying themselves rapidly. But after installing avast, I observed it only blocked new copy of the worms to be created but could not delete the already created worms, even it could not find worms in a good amount. Then I downloaded Malwarewbyte Anti Malware and to my surprise I found out its service was way too better than Avast antivirus. It detected and deleted almost 2065 worms and malwares from my computer and now my computer is doing fine. As far as I know, anti malware functionality is also included in Antivirus, But then also its performance is poor. Now my question is if performance of antiviruses are meat to be poor than Antimalwares, then why the size of Avast is 179Mb and the size of Malwarebyte is 9.81mb?

• Inheritance, commands and event sourcing

  - by Arthis

  In order not to redo things several times I wanted to factorize common stuff. For Instance, let's say we have a cow and a horse. The cow produces milk, the horse runs fast, but both eat grass. public class Herbivorous { public void EatGrass(int quantity) { var evt= Build.GrassEaten .WithQuantity(quantity); RaiseEvent(evt); } } public class Horse : Herbivorous { public void RunFast() { var evt= Build.FastRun; RaiseEvent(evt); } } public class Cow: Herbivorous { public void ProduceMilk() { var evt= Build.MilkProduced; RaiseEvent(evt); } } To eat Grass, the command handler should be : public class EatGrassHandler : CommandHandler<EatGrass> { public override CommandValidation Execute(EatGrass cmd) { Contract.Requires<ArgumentNullException>(cmd != null); var herbivorous= EventRepository.GetById<Herbivorous>(cmd.Id); if (herbivorous.IsNull()) throw new AggregateRootInstanceNotFoundException(); herbivorous.EatGrass(cmd.Quantity); EventRepository.Save(herbivorous, cmd.CommitId); } } so far so good. I get a Herbivorous object , I have access to its EatGrass function, whether it is a horse or a cow doesn't matter really. The only problem is here : EventRepository.GetById<Herbivorous>(cmd.Id) Indeed, let's imagine we have a cow that has produced milk during the morning and now wants to eat grass. The EventRepository contains an event MilkProduced, and then come the command EatGrass. With the CommandHandler, we are no longer in the presence of a cow and the herbivorious doesn't know anything about producing milk . what should it do? Ignore the event and continue , thus allowing the inheritance and "general" commands? or throw an exception to forbid execution, it would mean only CowEatGrass, and HorseEatGrass might exists as commands ? Thanks for your help, I am just beginning with these kinds of problem, and I would be glad to have some news from someone more experienced.

• How to pass a filename by drag-and-drop to a shortcut in Windows

  - by Kendall Frey

  I have a program program.exe and a document document.txt, and to open the document, I can drag document.txt onto program.exe. So far so good. Now I want to call it with a command-line parameter -param so that the full command line is program.exe -param document.txt Unfortunately, I can't do this with drag and drop, so I need to fire up cmd and type in the command manually. This takes too long, and I need an easier way. How can I create a shortcut that I can drop the file onto, and have it call the program with the command-line parameter? I tried setting the shortcut to program.exe -param "%1", but that didn't work, because it appeared to pass only the file name, and not the path, and since the current directory was the one with the program and not the one with the document, it couldn't find the document.

• How can I use iteration to lead targets?

  - by e100

  In my 2D game, I have stationary AI turrets firing constant speed bullets at moving targets. So far I have used a quadratic solver technique to calculate where the turret should aim in advance of the target, which works well (see Algorithm to shoot at a target in a 3d game, Predicting enemy position in order to have an object lead its target). But it occurs to me that an iterative technique might be more realistic (e.g. it should fire even when there is no exact solution), efficient and tunable - for example one could change the number of iterations to improve accuracy. I thought I could calculate the current range and thus an initial (inaccurate) bullet flight time to target, then work out where the target would actually be by that time, then recalculate a more accurate range, then recalculate flight time, etc etc. I think I am missing something obvious to do with the time term, but my aimpoint calculation does not currently converge after the significant initial correction in the first iteration: import math def aimpoint(iters, target_x, target_y, target_vel_x, target_vel_y, bullet_speed): aimpoint_x = target_x aimpoint_y = target_y range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) time_to_target = range / bullet_speed time_delta = time_to_target n = 0 while n <= iters: print "iteration:", n, "target:", "(", aimpoint_x, aimpoint_y, ")", "time_delta:", time_delta aimpoint_x += target_vel_x * time_delta aimpoint_y += target_vel_y * time_delta range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) new_time_to_target = range / bullet_speed time_delta = new_time_to_target - time_to_target n += 1 aimpoint(iters=5, target_x=0, target_y=100, target_vel_x=1, target_vel_y=0, bullet_speed=100)

• Are folders and filenames starting with "icon" illegal in SMB?

  - by dash-tom-bang

  Are five letter filenames starting with "icon" illegal in SMB? I just got a Drobo FS, in part to back up the computers in my house, and it does not accept folders named 'icons', 'iconv', or indeed I tried a bunch of other icon plus one letter names. I got errors on creation of these folders although now I don't remember the exact error. It has been confirmed with Drobo support that they "veto" files and folders named like this, due to them being illegal in the SMB spec. My Google skills so far have not been sufficient to turning any information on this up, however, so I wonder if anyone knows what's up? Sadly I can create these files and folders from my Mac, which I guess connects using AFP? But then I can't see them on my Windows machines. This is of little help if it is my Windows machines that I want to back up, and those being the ones with folders named like this. Thanks.

• bash code in rc.local not excuting after bootup

  Does anyone know why a system would not execute the script code within rc.local on bootup? I have a post configuration bash script that I want to run after the initial install of VMware ESX (Red Hat), and for some reason it doesn't seem to execute. I have the setup to log its start of execution and even its progress so that I can see how far it gets in case it fails at some point, but even when I look at that log, I am finding that didn't even started the execution of the script code. I already checked to see that script has execution permissions (755), what else should I be looking at? Here is the first few lines of my code: #!/bin/sh echo >> /tmp/configLog "" echo >> /tmp/configLog "Entering maintenance mode"

• Hide Content for Printing

  - by ltang

  Current, our users can view SCORM contents using frames. We would like to disable print or hide the content for printing. So far, we have tried: @media print { body { display:none } frameset {display:none} } The above line worked very inconsistently. For example, using IE8, the print preview does not show the content but when printing without preview it shows the content. Ideally we would like to disable printing altogether when our users launch any contents. If this can't be done, we would like to hide the print content so the users will print a blank page. Additionally, we would also like to disable the print screen option if possible. Please help!!!

• Mac OS needs Windows Live Writer &ndash; badly!

  - by digitaldias

  I recently bought a new  Macbook Pro (the 13” one) to dive into a new world of programming challenges as well as to get a more powerful netbook than my Packard Bell Dot which I’ve been using since last year. I’ve had immense pleasure using the netbook format and their small size in meetings (taking notes with XMind), surfing “anywhere”, and, of course blogging with windows live writer. So far the Mac is holding up, it’s sleek, responsive, and I’ve even begun looking at coding in Objective C with it, but in one arena, it is severely lacking: Blogging software. There is nothing that even comes close to Live Writer for getting your blog posts out. The few blogger applications that do exist on mac both look and feel medieval in comparison, AND some even cost money! It looks like some mac users actually install a virtual machine on their mac to run Windows XP just so they can use WLW. I’m not that extreme; instead, I’m hoping that the WLW team will write it’s awesome application as a Silverlight 4 app. That way, it would run on Mac and Windows (as a desktop app). I wonder if it will ever happen though…   PS: The image is of me, took it with the built-in camera on the mac and emailed it to the windows PC that I am writing on :)
