  • performance of vmware-machine on different computers

    - by bxshi
    I'm working on a filesystem improving project, and found a paper says the cheating on benchmark, and it gives a solution that use VMs could help others to reproduce our result. And the question is, if I have made a specific vmware virtual machine, will it runs the same at different computer and platform? For example, I have a virtual machine which is 1G RAM, 4G HD and 2G one-core CPU. Will that runs the same at a qual-core 3G CPU and a 2.4G P4? What if the computer have 4G RAM? Will vmware use some buffer mechanism to improve performance? If that's true, does it means the VM runs on a 2G RAM host will slower than on a 4G host? Hope you can help me on that, or just told me where could I find the answer.

  • Windows 7 installation: drive selection doesn't show drive letter

    - by FrozenKing
    I am eager to get this answer i.e. in Windows 7 when we format the computer there is a problem that when we have to select drive for formatting, it doesn't show drive letter. *I need a solution wherein when I format I want to know its drive letter so that I may not be confused while formatting. *See the difference between windows xp and windows 7. I want windows 7 to show drive letters like windows xp. Does any one know why windows 7 doesn't show drive letters.

  • How to ignore query parameters in web cache?

    - by eduardocereto
    Google Analytics use some query parameters to identify campaigns and to do cookie control. This is all handled by javascript code. Take a look at the following example: http://www.example.com/?utm_source=newsletter&utm_medium=email&utm_ter m=October%2B2008&utm_campaign=promotion This will set cookies via JavaScript with the right campaign origin. This query parameters can have multiple and sometimes random values. Since they are used as cache hash keys the cache performance is heavily degraded in some scenarios. I suppose there's a not so hard configuration on cache servers to just ignore all query parameters or specific query parameters. Am I right? Does anyone know how hard is it in popular web cache solutions, to create ? I'm not interested in a specific web cache solution. It would be great to hear about the one you use.

  • Ubuntu 10.10 strange USB file Permissions

    - by Christian Hubinger
    Hi, I'm developing a cross-plattform application that is delivered an run dirctly form an USB stick. As FAT32 ist the only FS working well for this (rw on windos/linux/mac) we use it as the FS for the stick. My Problem is that from Ubuntu 10.4 - 10.10 something changed at mounting the stick is mounted with files: rw-rw-r directories: rwxrwxr-x and (that is really strange) the Win32 Version of the application app.exe: rwxrwxr-x I tried for quit a while to find out where this is configured but could not find it - simple udev rule with MODE="0777" simpyl gets ignored. Any kind of idea help is very, very welcome, as not being able to find a solution for this is a real show stopper. thanks in advance and kind regards, Chris

  • Create Windows Bootloader/Boot into Windows from Ubuntu

    - by Kincaid
    I have computer that dual-boots (or tri-boots) Windows 8 Release Preview, Windows 7, and Ubuntu 12.04. Grub boots between Windows 8 and Ubuntu; for which I use primarily. Recently, I have decided I wanted to remove Ubuntu, as I hardly used it. As a stupid mistake, I deleted the Ubuntu partition before changing the bootloader to replace Grub. Whenever I know boot the machine, it gives me the "grub-rescue" prompt -- I am unable to boot into either Windows (8 nor 7), nor Ubuntu (except via USB, of course). I do not have any Windows 7/8 recovery media, so that isn't an option. Please note that after I deleted the Ubuntu partition, I put the PC into hibernate, and then turned it on. This means the C:\ [Windows 8] drive cannot be mounted. I don't know if that is bad, but it definitely doesn't make things better. I am currently booting Ubuntu via USB, in an effort to restore the Windows bootloader solutions. I have looked into using boot-repair to solve the problem using the instructions here, although after attempting to apply the changes, it gave the error: "Please install the [mbr] packages. Then try again." I don't know why I'm getting this error; is there a way to install the 'mbr packages?' I honestly don't know what exactly they are, nor how to install them. Is there any options I have not yet exhausted to be able to boot back into Windows, in the case that there is a better way? In the end, I want to set the bootloader to boot into Windows 8, but booting into either Windows 7 or 8 is fine -- I can use EasyBCD from there. Is there a simple solution to this? I've checked BIOS, and I haven't been able to find a way to boot into Windows. Any help would be greatly appreciated.

  • SQL Saturday 43 in Redmond

    - by AjarnMark
    I attended my first SQLSaturday a couple of days ago, SQLSaturday #43 in Redmond (at Microsoft).  I got there really early, primarily because I forgot how fast I can get there from my home when nobody else is on the road.  On a weekday in rush hour traffic, that would have taken two hours to get there.  I gave myself 90 minutes, and actually got there in about 45.  Crazy! I made the mistake of going to the main Microsoft campus, but that’s not where the event was being held.  Instead it was in a big Microsoft conference center on the other side of the highway.  Fortunately, I had the address with me and quickly realized my mistake.  When I got back on track, I noticed that there were bright yellow signs out on the street corner that looked like they said they were for SOL Saturday, which actually was appropriate since it was the sunniest day around here in a long time. Since I was there so early, the registration was just getting setup, so I found Greg Larsen who was coordinating things and offered to help.  He put me to work with a group of people organizing the pre-printed raffle tickets and stuffing swag bags. I had never been to a SQLSaturday before this one, so I wasn’t exactly sure what to expect even though I have read about a few on some blogs.  It makes sense that each one will be a little bit different since they are almost completely volunteer driven, and the whole concept is still in its early stages.  I have been to the PASS Summit for the last several years, and was hoping for a smaller version of that.  Now, it’s not really fair to compare one free day of training run entirely by volunteers with a multi-day, $1,000+ event put on under the direction of a professional event management company.  But there are some parallels. At this SQLSaturday, there was no opening general session, just coffee and pastries in the common area / expo hallway and straight into the first group of sessions.  I don’t know if that was because there was no single room large enough to hold everyone, or for other reasons.  This worked out okay, but the organization guy in me would have preferred to have even a 15 minute welcome message from the organizers with a little overview of the day.  Even something as simple as, “Thanks to persons X, Y, and Z for helping put this together…Sessions will start in 20 minutes and are all in rooms down this hallway…the bathrooms are on the other side of the conference center…lunch today is pizza and we would like to thank sponsor Q for providing it.”  It doesn’t need to be much, certainly not a full-blown Keynote like at the PASS Summit, but something to use as a rallying point to pull everyone together and get the day off to an official start would be nice.  Again, there may have been logistical reasons why that was not feasible here.  I’m just putting out my thoughts for other SQLSaturday coordinators to consider. The event overall was great.  I believe that there were over 300 in attendance, and everything seemed to run smoothly.  At least from an attendee’s point of view where there was plenty of muffins in the morning and pizza in the afternoon, with plenty of pop to drink.  And hey, if you’ve got the food and drink covered, a lot of other stuff could go wrong and people will be very forgiving.  But as I said, everything appeared to run pretty smoothly, at least until Buck Woody showed up in his Oracle shirt.  Other than that, the volunteers did a great job! I was a little surprised by how few people in my own backyard that I know.  It makes sense if you really think about it, given how many companies must be using SQL Server around here.  I guess I just got spoiled coming into the PASS Summit with a few contacts that I already knew would be there.  Perhaps I have been spending too much time with too few people at the Summits and I need to step out and meet more folks.  Of course, it also is different since the Summit is the big national event and a number of the folks I know are spread out across the country, so the Summit is the only time we’re all in the same place at the same time.  I did make a few new contacts at SQLSaturday, and bumped into a couple of people that I knew (and a couple others that I only knew from Twitter, and didn’t even realize that they were here in the area). Other than the sheer entertainment value of Buck Woody’s session, the one that was probably the greatest value for me was a quick introduction to PowerShell.  I have not done anything with it yet, but I think it will be a good tool to use to implement my plans for automated database recovery testing.  I saw just enough at the session to take away some of the intimidation factor, and I am getting ready to jump in and see what I can put together in the next few weeks.  And that right there made the investment worthwhile.  So I encourage you, if you have the opportunity to go to a SQLSaturday event near you, go for it!

  • Ricoh Aficio 1515ps - How can I get the scanner to scan? (printing works)

    - by nutty about natty
    For similar screenshots and story, see: How to define my Samsung SCX3200 multifunction printer? and for a possible solution: How can I get an Epson TX560WD scanner working? Thanks! Edit n°1 installed xsane (via Ubuntu Software Center), launched it and get the following: Clicking on "Help" yields: I tried 4) man sane-dll which yields No manual entry for sane-dll I uninstalled "Simple Scan": didn't help. I tried 3) but aborted due to unsettling warning ;) wasn't that brave (or desperate). Maybe it's due to 1) and I'm stuck with it? Is it really not possible that a driver for either Windoze or Mac OS would also support scanning via Ubuntu? Edit n°2 Resorted to Windows XP and the Network TWAIN Driver ScanRouter or the "lite" version (which I found elsewhere) might also work (under Linux??); but it's more than I need. Thought about WINE, but also that seems to rely on SANE... So still no luck with this device's scanning capabilities with Linux (but good enough (via xp) for my purposes)...

  • Mapping drives on MacOSX (Leopard/Snow Leopard) permanently inside LAN

    - by Shyam
    Hi, How do I "map" shared folders on a Mac, permanently? With map, I do not mean 'connect', but permanently add it to the system so it exists after reboot. Since workstations tend to shutdown, I wonder also the symptoms and cures in case that happens. In Linux, this can be done using the fstab file, but I noticed that volumes are mounted in a different structure than Linux. I need this to backup some workstations, doing a recursive job over a single directory, that should contain the shared folders. I use Terminal to access the main system, so by preference, the solution would be nice that works within a bash shell vs GUI. I can access all folders in Finder. Thanks!

  • Unleash AutoVue on Your Unmanaged Data

    - by [email protected]
    Over the years, I've spoken to hundreds of customers who use AutoVue to collaborate on their "managed" data stored in content management systems, product lifecycle management systems, etc. via our many integrations. Through these conversations I've also learned a harsh reality - we will never fully move away from unmanaged data (desktops, file servers, emails, etc). If you use AutoVue today you already know that even if your primary use is viewing content stored in a content management system, you can still open files stored locally on your computer. But did you know that AutoVue actually has - built-in - a great solution for viewing, printing and redlining your data stored on file servers? Using the 'Server protocol' you can point AutoVue directly to a top-level location on any networked file server and provide your users with a link or shortcut to access an interface similar to the sample page shown below. Many customers link to pages just like this one from their internal company intranets. Through this webpage, users can easily search and browse through file server data with a 'click-and-view' interface to find the specific image, document, drawing or model they're looking for. Any markups created on a document will be accessible to everyone else viewing that document and of course real-time collaboration is supported as well. Customers on maintenance can consult the AutoVue Admin guide or My Oracle Support Doc ID 753018.1 for an introduction to the server protocol. Contact your local AutoVue Solutions Consultant for help setting up the sample shown above.

  • One domain hiding two servers

    - by George DSeas
    For our SaaS web-app we have two identical servers in two geographically separated data centers. FOO_1 is the production server and does real-time (MySQL master-slave) replication to its backup F00_2. We want our users to always go to THEFOO.COM which somehow points to the production server. So even if FOO_1 dies, we can just switch THEFOO.COM to redirect to FOO_2 so the failure is transparent. This switch can be manual or automatic but without failback (if FOO_1 somehow becomes available again). Is there a way to do this with DNS? I am getting stuck with ANAME and CNAMEs configuration. We don't use sub-domains, just straight domains. If not, what are other options? Does it make sense to just have a web server at LOVELY_FOO.COM and just redirect all traffic? I also looked at load balancers but didn't see a solution for across data centers/network providers.

  • Unable to cast transparent proxy to type &lt;type&gt;

    - by Rick Strahl
    This is not the first time I've run into this wonderful error while creating new AppDomains in .NET and then trying to load types and access them across App Domains. In almost all cases the problem I've run into with this error the problem comes from the two AppDomains involved loading different copies of the same type. Unless the types match exactly and come exactly from the same assembly the typecast will fail. The most common scenario is that the types are loaded from different assemblies - as unlikely as that sounds. An Example of Failure To give some context, I'm working on some old code in Html Help Builder that creates a new AppDomain in order to parse assembly information for documentation purposes. I create a new AppDomain in order to load up an assembly process it and then immediately unload it along with the AppDomain. The AppDomain allows for unloading that otherwise wouldn't be possible as well as isolating my code from the assembly that's being loaded. The process to accomplish this is fairly established and I use it for lots of applications that use add-in like functionality - basically anywhere where code needs to be isolated and have the ability to be unloaded. My pattern for this is: Create a new AppDomain Load a Factory Class into the AppDomain Use the Factory Class to load additional types from the remote domain Here's the relevant code from my TypeParserFactory that creates a domain and then loads a specific type - TypeParser - that is accessed cross-AppDomain in the parent domain:public class TypeParserFactory : System.MarshalByRefObject,IDisposable { …/// <summary> /// TypeParser Factory method that loads the TypeParser /// object into a new AppDomain so it can be unloaded. /// Creates AppDomain and creates type. /// </summary> /// <returns></returns> public TypeParser CreateTypeParser() { if (!CreateAppDomain(null)) return null; /// Create the instance inside of the new AppDomain /// Note: remote domain uses local EXE's AppBasePath!!! TypeParser parser = null; try { Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); } catch (Exception ex) { this.ErrorMessage = ex.GetBaseException().Message; return null; } return parser; } private bool CreateAppDomain(string lcAppDomain) { if (lcAppDomain == null) lcAppDomain = "wwReflection" + Guid.NewGuid().ToString().GetHashCode().ToString("x"); AppDomainSetup setup = new AppDomainSetup(); // *** Point at current directory setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; //setup.PrivateBinPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin"); this.LocalAppDomain = AppDomain.CreateDomain(lcAppDomain,null,setup); // Need a custom resolver so we can load assembly from non current path AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve); return true; } …} Note that the classes must be either [Serializable] (by value) or inherit from MarshalByRefObject in order to be accessible remotely. Here I need to call methods on the remote object so all classes are MarshalByRefObject. The specific problem code is the loading up a new type which points at an assembly that visible both in the current domain and the remote domain and then instantiates a type from it. This is the code in question:Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); The last line of code is what blows up with the Unable to cast transparent proxy to type <type> error. Without the cast the code actually returns a TransparentProxy instance, but the cast is what blows up. In other words I AM in fact getting a TypeParser instance back but it can't be cast to the TypeParser type that is loaded in the current AppDomain. Finding the Problem To see what's going on I tried using the .NET 4.0 dynamic type on the result and lo and behold it worked with dynamic - the value returned is actually a TypeParser instance: Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; object objparser = this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); // dynamic works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // casting fails parser = (TypeParser)objparser; So clearly a TypeParser type is coming back, but nevertheless it's not the right one. Hmmm… mysterious.Another couple of tries reveal the problem however:// works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // c:\wwapps\wwhelp\wwReflection20.dll (Current Execution Folder) string info3 = typeof(TypeParser).Assembly.CodeBase; // c:\program files\vfp9\wwReflection20.dll (my COM client EXE's folder) string info4 = dynParser.GetType().Assembly.CodeBase; // fails parser = (TypeParser)objparser; As you can see the second value is coming from a totally different assembly. Note that this is even though I EXPLICITLY SPECIFIED an assembly path to load the assembly from! Instead .NET decided to load the assembly from the original ApplicationBase folder. Ouch! How I actually tracked this down was a little more tedious: I added a method like this to both the factory and the instance types and then compared notes:public string GetVersionInfo() { return ".NET Version: " + Environment.Version.ToString() + "\r\n" + "wwReflection Assembly: " + typeof(TypeParserFactory).Assembly.CodeBase.Replace("file:///", "").Replace("/", "\\") + "\r\n" + "Assembly Cur Dir: " + Directory.GetCurrentDirectory() + "\r\n" + "ApplicationBase: " + AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "\r\n" + "App Domain: " + AppDomain.CurrentDomain.FriendlyName + "\r\n"; } For the factory I got: .NET Version: 4.0.30319.239wwReflection Assembly: c:\wwapps\wwhelp\bin\wwreflection20.dllAssembly Cur Dir: c:\wwapps\wwhelpApplicationBase: C:\Programs\vfp9\App Domain: wwReflection534cfa1f For the instance type I got: .NET Version: 4.0.30319.239wwReflection Assembly: C:\\Programs\\vfp9\wwreflection20.dllAssembly Cur Dir: c:\\wwapps\\wwhelpApplicationBase: C:\\Programs\\vfp9\App Domain: wwDotNetBridge_56006605 which clearly shows the problem. You can see that both are loading from different appDomains but the each is loading the assembly from a different location. Probably a better solution yet (for ANY kind of assembly loading problem) is to use the .NET Fusion Log Viewer to trace assembly loads.The Fusion viewer will show a load trace for each assembly loaded and where it's looking to find it. Here's what the viewer looks like: The last trace above that I found for the second wwReflection20 load (the one that is wonky) looks like this:*** Assembly Binder Log Entry (1/13/2012 @ 3:06:49 AM) *** The operation was successful.

WRN: It is recommended to inspect your application on whether this is intentional or not. WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue. Notice that the fusion log clearly shows that the .NET loader makes no attempt to even load the assembly from the path I explicitly specified. Remember your Assembly Locations As mentioned earlier all failures I've seen like this ultimately resulted from different versions of the same type being available in the two AppDomains. At first sight that seems ridiculous - how could the types be different and why would you have multiple assemblies - but there are actually a number of scenarios where it's quite possible to have multiple copies of the same assembly floating around in multiple places. If you're hosting different environments (like hosting the Razor Engine, or ASP.NET Runtime for example) it's common to create a private BIN folder and it's important to make sure that there's no overlap of assemblies. In my case of Html Help Builder the problem started because I'm using COM interop to access the .NET assembly and the above code. COM Interop has very specific requirements on where assemblies can be found and because I was mucking around with the loader code today, I ended up moving assemblies around to a new location for explicit loading. The explicit load works in the main AppDomain, but failed in the remote domain as I showed. The solution here was simple enough: Delete the extraneous assembly which was left around by accident. Not a common problem, but one that when it bites is pretty nasty to figure out because it seems so unlikely that types wouldn't match. I know I've run into this a few times and writing this down hopefully will make me remember in the future rather than poking around again for an hour trying to debug the issue as I did today. Hopefully it'll save some of you some time as well in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  COM   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • adding mongo to path

    - by Mike
    Bit of a noob question. I have downloaded MongoDb and installed it here /Users/mike/downloads/mongodb In order to start it, I then have to 'cd' into the 'bin' /Users/mike/downloads/mongodb/bin and run ./mongod (to start the database) and ./mongo (to start the mongo shell) The problem is that I can only work with python and ruby scripts using the mongo shell if I have those scripts stored in the same bin directory, and I don't think that's the ideal set up. Will exporting the path allow me to access mongo from outside the bin? For example, I would prefer to have my ruby scripts in /sites/ruby and be able to access mongo by starting ruby in /sites/ruby. If exporting to path is the solution, how do I do that. I'm using a mac

  • Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 server?

    - by Vorleak Chy
    I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me. I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate. Does anyone know a solution?

  • Edge Detection on Screen

    - by user2056745
    I have a edge collision problem with a simple game that i am developing. Its about throwing a coin across the screen. I am using the code below to detect edge collisions so i can make the coin bounce from the edges of the screen. Everything works as i want except one case. When the coin hits left edge and goes to right edge the system doesnt detect the collision. The rest cases are working perfectly, like hitting the right edge first and then the left edge. Can someone suggest a solution for it? public void onMove(float dx, float dy) { coinX += dx; coinY += dy; if (coinX > rightBorder) { coinX = ((rightBorder - coinX) / 3) + rightBorder; } if (coinX < leftBorder) { coinX = -(coinX) / 3; } if (coinY > bottomBorder) { coinY = ((bottomBorder - coinY) / 3) + bottomBorder; } invalidate(); }

  • I'm scared for my technical phone interview for an internship!

    - by Marie
    [EDIT 2.0 ]Hello everyone. This is my second phone interview for a development internship. My very first one was okay, but I didn't get my dream internship. Now, I'm facing fears about this upcoming interview. My fears include the following: I'm 19 years old. The thought of 2 lead developers interviewing me makes me think that I'll know so little of what they'd want me to know. Like they will expect so much. I'm a junior having these panic attacks that I did not get in the other internship. I have a little voice saying "You didn't get the other one. What makes you think you'll get this one?". I'm scared that I'll freeze up, forget everything I know, and stutter like an idiot. I'm still traumatized by the last one, because I really really wanted that internship, and I even studied very hard for it. When I was in the interview, I was so nervous I couldn't think clearly. As a result, I didn't do as well as I know I could have. The minute I hung up, I even thought of a better solution to the interview question! Any tips for a soon-to-be intern (hopefully!)? Thank you! P.S. I'm preparing by using this guide for phone interviews.

  • How to disable or edit Google Chrome Developer Tools shortcut?

    - by HoLyVieR
    There is a shortcut in the Google Chrome Developer Tools which happen to trigger every times I try to type the [ or ] character in the console. The shortcut in question probably is Alt+[, Alt+^ or [ and it moves the tabs (of the Chrome Developer Tools) to the last selected one. This shortcut is simply blocking me from typing the [ or ] in the console and I want to either disable it or edit it to something else. How can I edit or disable that shortcut ? Note : I'm not really using the shortcut in the developers tools, so if it's only possible to disable all shortcut it would be a viable solution.

  • Where do I place XNA content pipeline references?

    - by Zabby Wabby
    I am relatively new to XNA, and have started to delve into the use of the content pipeline. I have already figured out that tricky issue of adding a game library containing classes for any type of .xml file I want to read. Here's the issue. I am trying to handle the reading of all XML content through use of an XMLHandler object that uses the intermediate deserializer. Any time reading of such data is required, the appropriate method within this object would be called. So, as a simple example, something like this would occur when a character levels: public Spell LevelUp(int levelAchived) { XMLHandler.FindSkillsForLevel(levelAchived); } This method would then read the proper .xml file, sending back the spell for the character to learn. However, the XMLHandler is having issues even being created. I cannot get it to use the using namespace of Microsoft.Xna.Framework.Content.Pipeline. I get an error on my using statement in the XMLHandler class: using Microsoft.Xna.Framework.Content.Pipeline.Serialization.Intermediate; The error is a typical reference error: Type or namespace name "'Pipeline' does not exist in the namespace 'Microsoft.Xna.Framework.Content' (are you missing an assembly reference?)" I THINK this is because this namespace is already referenced in my game's content. I would really have no issue placing this object within my game's content (since that is ALL it deals with anyways), but the Content project does not seem capable of holding anything but content files. In summary, I need to use the Intermediate Deserializer in my main project's logic, but, as far as I can make out, I can't safely reference the associated namespace for it outside of the game's content. I'm not a terribly well-versed programmer, so I may be just missing some big detail I've never learned here. How can I make this object accessible for all projects within the solution? I will gladly post more information if needed!

  • EC2 instance store cloning or to ebs via gui management console

    - by devnull
    I have found similar questions here but the answer are either outdated or are from the command line. The case is this. I have an EC2 instance using instance store (this was the only AMI available for Debian 6 in Ireland). Now through the AWS GUI I can do a snapshot of the instance volume and/or even create a volume. But an image made from the snapshot doesn't boot. What is the best solution to either clone an EC2 instance that uses instance store OR from the created snapshot of the instance store to launch a new EBS instance (identical clone) FROM the gui aws management console and not command line ? Before turning this down consider that there is not similar question on how to do it via the aws management console. hint can't be done is not an appropriate answer. As you can create a snapshot of the instance store backed instance and/or a volume and create an AMI from that snapshot.

  • Adding SSE support in Java EE 8

    - by delabassee
    SSE (Server-Sent Event) is a standard mechanism used to push, over HTTP, server notifications to clients.  SSE is often compared to WebSocket as they are both supported in HTML 5 and they both provide the server a way to push information to their clients but they are different too! See here for some of the pros and cons of using one or the other. For REST application, SSE can be quite complementary as it offers an effective solution for a one-way publish-subscribe model, i.e. a REST client can 'subscribe' and get SSE based notifications from a REST endpoint. As a matter of fact, Jersey (JAX-RS Reference Implementation) already support SSE since quite some time (see the Jersey documentation for more details). There might also be some cases where one might want to use SSE directly from the Servlet API. Sending SSE notifications using the Servlet API is relatively straight forward. To give you an idea, check here for 2 SSE examples based on the Servlet 3.1 API.  We are thinking about adding SSE support in Java EE 8 but the question is where as there are several options, in the platform, where SSE could potentially be supported: the Servlet API the WebSocket API JAX-RS or even having a dedicated SSE API, and thus a dedicated JSR too! Santiago Pericas-Geertsen (JAX-RS Co-Spec Lead) conducted an initial investigation around that question. You can find the arguments for the different options and Santiago's findings here. So at this stage JAX-RS seems to be a good choice to support SSE in Java EE. This will obviously be discussed in the respective JCP Expert Groups but what is your opinion on this question?

  • Average SPA weight [on hold]

    - by Emmanuel Istace
    First, sorry my noobs questions, but I'm mainly Windows Developer and not Web Developer :) I'm developing a single page application with a lot of css & javascript. For now the page is 1.3Mo composed by 5 section. Here are the rounded stats : Document : 10kb Style : 60kb Images : 450 kb (already compressed, include a big gallery thumbnails) Javascript : 700kb - 600kb of "framework" (jquery, jquery-ui, boostrap, modernizer, waypoint, ...) and 100kb of custom js. Fonts : 125kb And the site is not finished yet. (Will include gmap api, and some others...) My questions are : Do you have any statistics about the average weight of an SPA ? As this is the whole website, do you think it's acceptable ? Is lazy load (for images) a solution ? What will be impact for SEO ? Is the "200kb rule" of google still relevant ? Do you know great tools to detect which javascript code is not used during the the exection of a page and then the availability to optimize these 700kb of framework js stuffs ? Can a caching strategy be an answer ? Thank you in advance for you help ! Best regards

  • Setting up fail2ban to ban failed phpMyAdmin login attempts

    - by Michael Robinson
    We've been using fail2ban to block failed ssh attempts. I would like to setup the same thing for phpMyAdmin as well. As phpMyAdmin doesn't log authentication attempts to a file (that I know of), I'm unsure of how best to go about this. Does a plugin / config exist that makes phpMyAdmin log authentication attempts to a file? Or is there some other place I should look for such an activity log? Ideally I will be able to find a solution that involved modifying fail2ban config only, as I have to configure fail2ban with the same options on multiple servers, and would prefer not to also modify the various phpMyAdmin installations on said servers.

  • How to prevent any files from being copied onto the Desktop?

    - by Kaushik Gopal
    Gentlepeeps, Is there any solution to prevent copying of files onto the desktop? My folks and i currently have one super-common-comp in our place. And when all of the laptops are busy, we tend to do some quick surfing on this comp. I prefer to keep things freakishly organized in this comp and one thing i hate is having those off-shoot irritating forwarded downloads on my desktop. Is there some way to restrict files from being copied onto the desktop? I tried making the administrator user's desktop folder as read-only :P . That doesn't solve the problem. Any other ideas/software/solutions? cheers.

  • Proper way to remove an active / inactive LVM snapshot

    - by user2622247
    I have created a sample ruby script file for removing extra LVM snapshots from the system. For removing LVM snapshot, we are using lvremove command. This command is working fine and we can remove snapshots from the system. # sudo lvremove /dev/ops/dbbackup lvremove -- do you really want to remove "/dev/ops/dbbackup"? [y/n]: y Sometimes while removing snapshots we are getting following errors. Unable to deactivate open rootfs_12.10_20140812_00-cow (252:8) Failed to resume rootfs_12.10_20140812_00. libdevmapper exiting with 7 device(s) still suspended. The system gets frozen. We cannot fire any command or can not perform any action on it. After restarting the system, it is functioning fine. We can perform all the operations even we can delete that snapshot also. I searched about it I found these threads https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=659762 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=674682 Solution from this thread is after getting the error but I have to avoid this type of error. I have a question, Is there any better way removing LVM snapshots? So that we can avoid this type of error. If anyone needs more info feel free to ask me.
