  • What's wrong with Lotus Notes / Lotus Domino?

    - by user20242
    I have a client who is using Lotus Domino for their web application/server platform. The client has two "web developers" who are more comfortable with Lotus Domino than more mainstream tools and technologies and are not enthusiastic about making a switch. I have been asked to provide an assessment of why it may be prudent to migrate to a different web application platform. I would be particularly interested in understanding deficiencies related to the platform as I have very little knowledge of Domino but am very familiar with other platforms. In addition to the fact that Apache has over 70% of web server market, IIS over 21%, and Lotus almost 0%, what other reasons would you give for moving away from this platform?

  • Is Mac OS X open source?

    - by hasen j
    I learned recently (on superuser) that Mac OS X uses the bash shell. I also know that OS X has a UNIX core. I was searching for information about OS X and Open Source on google, but what I found was this site: http://www.opensource.apple.com/ Which seems to include the source code for OS X. For instance, one of the links reads: Mac OS X 10.5.7 Source So, is OS X open source? There's an Apple Public Source License, but I'm bad at understanding legalese. Update Extra/Bonus question: Besides the kernel, What about the various other pieces? The X server? Window Manager? File explorer? etc. What's open source and what's not?

  • What is the best way to configure Apache or AWS to support a Rails multi tenancy application that allows each customer to have their own domain name?

    - by Ryan Arneson
    I'm building a Rails 3 SaaS site that allows for multi-tenancy. When a customer signs up they put in their own domain name, e.g. example.com. I need example.com to point to my SaaS application and serve them their content. My questions are as follows: Do I need to create an Apache vhost for each customer using their own domain? Is there an easier way with CNAME's to just have the customer point to the IP address of my server(s) that then forwards the request onto my application through some catch all vhost? Would I be able to create the CNAME record for the customer so they don't have to do any setup? Would this be a case better suited to Amazon Web Services? Any help or explanation or corrections on my understanding of dns would be appreciated. I'm a developer so the server ops portion of this is a bit cloudy.

  • Connecting CR 2008 and Oracle database: "TNS file could not be opened"

    - by anand
    I am trying to connect to an Oracle database using CR 2008 drivers for oracle (specifically OLE db driver). When I try to connect I provide the correct connection parameters however I keep getting "TNS file could not be opened" error. I am very confused about this message does this mean I am missing some component? From my understanding the driver should be able to connect. Currently on the computer running Crystal reports there is only has Crystal reports 2008 installed. Do i need to install the oracle instant client on the CR computer in order to make a proper connection? Any suggestions would be greatly appreciated!

  • Far jump in ntdll.dll's internal ZwCreateUserProcess

    - by user49164
    I'm trying to understand how the Windows API creates processes so I can create a program to determine where invalid exes fail. I have a program that calls kernel32.CreateProcessA. Following along in OllyDbg, this calls kernel32.CreateProcessInternalA, which calls kernel32.CreateProcessInternalW, which calls ntdll.ZwCreateUserProcess. This function goes: mov eax, 0xAA xor ecx, ecx lea edx, dword ptr [esp+4] call dword ptr fs:[0xC0] add esp, 4 retn 0x2C So I follow the call to fs:[0xC0], which contains a single instruction: jmp far 0x33:0x74BE271E But when I step this instruction, Olly just comes back to ntdll.ZwCreateUserProcess at the add esp, 4 right after the call (which is not at 0x74BE271E). I put a breakpoint at retn 0x2C, and I find that the new process was somehow created during the execution of add esp, 4. So I'm assuming there's some magic involved in the far jump. I tried to change the CS register to 0x33 and EIP to 0x74BE271E instead of actually executing the far jump, but that just gave me an access violation after a few instructions. What's going on here? I need to be able to delve deeper beyond the abstraction of this ZwCreateUserProcess to figure out how exactly Windows creates processes.

  • Is it possible to create a read-only user account for security auditing purposes?

    - by user2529583
    An organization requires several administrators to have a role of a security auditor. They must have read-only (via network/remote) access to Windows Server 2008 / R2 systems and have permissions to view the server configuration. They must not be able to make any other changes to the server or the network, like restarting or making any configuration chanages. However I can't find any built-in settings for a user like this. The closest thing is the "Users" user group [1], however from my understanding every user in the domain is in this group and cannot view the domain server's configuration. So, what are other options of implementing a read-only user account in Windows Server 2008? [1] http://technet.microsoft.com/en-us/library/cc771990.aspx

  • One bigger Virtual Machine in Cloud

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with e.g. 12 cores? ------------------------------- | VM (12c) | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | VM (4c) | VM (4c) | VM (4c) | ------------------------------- | Bare Metal (8c) | ------------------------------- I need this information to have a bigger picture to continue.

  • Chaotic behavior of a dead pixel on my iMac 24"

    - by Vincent Robert
    Since I bought my iMac last year, I have a white pixel on the left of my screen. I'm ok with that, one pixel is not much and I know about dead pixels policies. My problem is about understanding this "dead" pixel. But this pixel has a strange behavior. At first, it seems to be always white, but it is actually working ok under certain conditions: the mouse pointer a contextual menu Dock icons a QuickLooks video played in fullscreen other spaces than "1" The "QuickLooks fullscreen video" and "other spaces" are the one that disturb me the most. In these modes, my pixel is working fine, so it must be a software problem since my pixel is working correctly in those modes. Any ideas?

  • Mapping of memory addresses to physical modules in Windows XP

    - by Josef Grahn
    I plan to run 32-bit Windows XP on a workstation with dual processors, based on Intel's Nehalem microarchitecture, and triple channel RAM. Even though XP is limited to 4 GB of RAM, my understanding is that it will function with more than 4 GB installed, but will only expose 4 GB (or slightly less). My question is: Assuming that 6 GB of RAM is installed in six 1 GB modules, which physical 4 GB will Windows actually map into its address space? In particular: Will it use all six 1 GB modules, taking advantage of all memory channels? (My guess is yes, and that the mapping to individual modules within a group happens in hardware.) Will it map 2 GB of address space to each of the two NUMA nodes (as each processor has it's own memory interface), or will one processor get fast access to 3 GB of RAM, while the other only has 1 GB? Thanks!

  • Multiple ServerRoot directives in single apache

    - by fip
    i came across a apache httpd 2.2 configuration recently in which multiple ServerRoot-directives were defined, each followed by individual prefork Settings. Sort of like this: ServerRoot root1 <IfModule prefork.c> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> [vhost-configs] ServerRoot root2 <IfModule prefork.c> StartServers 10 MinSpareServers 10 MaxSpareServers 20 MaxClients 250 MaxRequestsPerChild 0 </IfModule> [vhost-configs] In my understanding these are global settings one overriding the other. But is that true and is it still true with the second ServerRoot directive between the prefork blocks? Thank you in advance EDIT They are not in different conditional blocks and both server roots are used in that way that files with relative paths to both are correctly included. I just wondered if a <ServerRoot> would initiate a new scope in which all global statements would not override the configuration of previous ones.

  • All my folders and files on my flash drive have been renamed automatically and I can no longer open them... I need those files

    - by jennifer
    I opened up my flash drive this morning and all of my folders and files are normal, except for one folder and all its included files, which is the most important folder. The subfolders and files are renamed with bizarre characters and when I click to open them, a pop-up appears saying it's not accessible and the filename or directory name is incorrect. I don't want to reformat the flash drive because I'd lose all those files. Is there a way for me to restore it or something? I would attach a screen shot, but apparently new users do not have that privilege. If you have a vague idea of what I'm talking about, let me know and I can email you screenshots so you can have a better understanding. Any help is greatly appreciated!

  • Help! I've learned jQuery... now I want to learn JavaScript

    - by Derek Adair
    I am a self-taught web developer/programmer. I started out about two years ago by learning how to make simple dynamic websites with HTML/CSS/PHP. Then I started dabbling with animation... Enter jQuery I've become quite proficient with jQuery over the last year and I've even started making my own plugins. I've spent most of my effort learning how to beautify websites with fancy effects and what not. Upon tackling my first full-blown application, I realized how under-developed my knowledge of JavaScript actually is. jQuery has allowed me to rely on its framework so heavily that I rarely use any interesting functions, techniques, or whatever that are 'native' to the JavaScript language. For example: I have a basic understanding of what a closure is... but I am unsure where this technique can actually benefit me. Although as I understand it, that's what my jQuery plugins do with (function ($){//plugin code here})(jQuery). I've seen many posts/blogs/whatever about memory leaks and circular references which is concerning. I'm frustrated because I can wrap my head around the basic concepts of what these are just by reading the articles, but I'm finding that the deeper I go the more I don't understand. The vocabulary alone is burdensome. Let alone how to actually use these techniques/functions/language features. I am trying to figure out what I don't know I'm looking to gather any advice, techniques, articles, books, videos, snippets, examples, potential pitfalls... really anything you have regarding application development with JavaScript/jQuery.

  • Are whole VM images backed up on Amazon EC2/S3?

    - by John
    I've been trying to get my head around Amazon Web Services as a VPS provider. My understanding is a EC2 instance running Windows is basically a Windows VM, very similar to renting a VPS from a more traditional hosting provider. I don't want to have complex backups, either to administer or to restore - if my restore involves installing SVN, MySQL, Jira, etc on a new box before I can even try to restore the backup then it's not great to me. What I really want is a service which backs up my entire VM... if the PC running the VPS dies then the VM image is installed on a new PC and off we go again. With Amazon being all about flexibility and elasticity, I wondered if they have this service? I can't figure it out from reading their docs.

  • default gateway of a host

    - by varun
    if my understanding is correct, the following is what happens when a host A wants to communicate with a machine X outside its network. 1) The host ,checks it routing table to find out if there is any direct routes to the machine. 2) It finds out that the machine is outside its network and has to sent the packets to the default gateway(router) R. 3) The host sents an ARP broadcast to get the mac of the router R. 4) After getting the MAC, the host creates a packet with src IP and MAC as that of the host A, dest IP of the remote machine X and dest MAC of the router R. 5)The router R receives the packet, either drops its or sents its to its next hope, which can be another router or the remote machine X itself. Can anyone explain, how the steps would be, if i set the default gateway of the host A as host A itself...?

  • Duck type testing with C# 4 for dynamic objects.

    - by Tracker1
    I'm wanting to have a simple duck typing example in C# using dynamic objects. It would seem to me, that a dynamic object should have HasValue/HasProperty/HasMethod methods with a single string parameter for the name of the value, property, or method you are looking for before trying to run against it. I'm trying to avoid try/catch blocks, and deeper reflection if possible. It just seems to be a common practice for duck typing in dynamic languages (JS, Ruby, Python etc.) that is to test for a property/method before trying to use it, then falling back to a default, or throwing a controlled exception. The example below is basically what I want to accomplish. If the methods described above don't exist, does anyone have premade extension methods for dynamic that will do this? Example: In JavaScript I can test for a method on an object fairly easily. //JavaScript function quack(duck) { if (duck && typeof duck.quack === "function") { return duck.quack(); } return null; //nothing to return, not a duck } How would I do the same in C#? //C# 4 dynamic Quack(dynamic duck) { //how do I test that the duck is not null, //and has a quack method? //if it doesn't quack, return null }

  • best practice with memcache/php - multi memcache nodes

    - by user62835
    So I am working on a web app - that has to be built for scalability. It stores frequent MySQL querys into the cache. I have pretty much everything built and ready to go - but I am concerned on best practices on handling where to cache the data. I've talked to a few people and one of them suggested to split each key/value across all the memcache nodes. Meaning if i store the example: 'somekey','this is the value' it will be split across lets say 3 memcache servers. Is that a better way? or is memcache more built on a 1 to 1 relationship?. For example. store value on server A till it faults out - go to server B and store there. that is my current understanding from the research I have done and past experience working with memcache. Could someone please point me in the right direction in this and let me know which way is best or if I completely have this mixxed up. Thanks

  • Change Data Capture or Change Tracking - Same as Traditional Audit Trail Table?

    - by HardCode
    Before I delve into the abyss of Microsoft documentation any deeper, I'd like to know if someone experienced with Change Data Capture and Change Tracking know if one or both of these can be used to replace the traditional ... "Audit trail table copy of the 'real table' (all of the fields of the original table, plus date/time, user ID, and DML action field) inserted into by Triggers" ... setup for a database table audit trail, where the trigger populates the audit trail table (which is all manual work). The MSDN overview documentation explains at a high level what Change Data Capture and Change Tracking are, but it isn't clear enough to me, and doesn't state outright, that these tools can be used to replace the traditional audit trail tables we've made so often. Can someone with any experience using Change Data Capture and Change Tracking save me a lot of time, or confirm that I am spending time looking at the right tool? The critical part of our audit trail is capturing all changes to a table's fields (on INSERT, UPDATE, DELETE), when it happened, and who did it. These changes are commonly provided to an end user chronologically via an audit trail report. Which is another question ... Change Data Capture or Change Tracking is the solution, I'd assume that this data can be queried just like data from a normal table? EDIT: I need a permanent audit trail, irregardless of time. I see that Change Data Capture has to do with the transaction logs, so this sounds finite to me.

  • Object hierarchy returned by WCF Service is different than expected

    - by robalot
    Good Day Everyone... My understanding may be wrong, but I thought once you applied the correct attributes the DataContractSerializer would render fully-qualified instances back to the caller. The code runs and the objects return. But oddly enough, once I look at the returned objects I noticed the namespacing disappeared and the object-hierarchy being exposed through the (web applications) service reference seems to become "flat" (somehow). Now, I expect this from a web-service…but not through WFC. Of course, my understanding of what WFC can do may be wrong. ...please keep in mind I'm still experimenting with all this. So my questions are… Q: Can I do something within the WFC Service to force the namespacing to render through the (service reference) data client proxy? Q: Or perhaps, am I (merely) consuming the service incorrectly? Q: Is this even possible? The service code looks like… [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] public class DataService : IFishData { public C1FE GetC1FE(Int32 key) { //… more stuff here … } public Project GetProject(Int32 key) { //… more stuff here … } } [ServiceContract] [ServiceKnownType(typeof(wcfFISH.StateManagement.C1FE.New))] [ServiceKnownType(typeof(wcfFISH.StateManagement.Project.New))] public interface IFishData { [OperationContract] C1FE GetC1FE(Int32 key); [OperationContract] Project GetProject(Int32 key); } [DataContract] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class Project { [DataMember] public wcfFISH.StateManagement.ObjectState ObjectState { get; set; } //… more stuff here … } [DataContract] KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class C1FE { [DataMember] public wcfFISH.StateManagement.ObjectState ObjectState { get; set; } //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement")] [KnownType(typeof(wcfFISH.StateManagement.C1FE.New))] [KnownType(typeof(wcfFISH.StateManagement.Project.New))] public abstract class ObjectState { //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement.C1FE", Name="New")] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class New : ObjectState { //… more stuff here … } [DataContract(Namespace = "wcfFISH.StateManagement.Project", Name = "New")] [KnownType(typeof(wcfFISH.StateManagement.ObjectState))] public class New : ObjectState { //… more stuff here … } The web application code looks like… public partial class Fish_Invite : BaseForm { protected void btnTest_Click(object sender, EventArgs e) { Project project = new Project(); project.Get(base.ProjectKey, base.AsOf); mappers.Project mapProject = new mappers.Project(); srFish.Project fishProject = new srFish.Project(); srFish.FishDataClient fishService = new srFish.FishDataClient(); mapProject.MapTo(project, fishProject); fishProject = fishService.AddProject(fishProject, IUser.UserName); project = null; } } In case I’m not being clear… The issue arises as there is a difference in (the name spacing) that I expect to see (returned) is different from what is actually returned. fishProject.ObjectState should look like... srFish.StateManagement.Project.New fishC1FE.ObjectState should look like... srFish.StateManagement.C1FE.New fishProject.ObjectState looks like... srFish.New1 fishC1FE.ObjectState looks like... srFish.New …“Help me Obi-Wan Kenobi, you’re my only hope!”

  • Detect and monitor changes to MySQL database

    - by Wolfpack'08
    I use Drupal, and instead of having to use the formal interface to make small changes to a site all the time, I am wondering if there is a way to determine what modifications Drupal makes to the database so that I can make them manually the next time. For example, if I use Drupal’s interface to add a module to the site, I would like to be able to find out what database entries it changes/adds so that if I want to add another module, I can add or change the file or database entry myself instead of having to go through Druapl. This way, I can have better control over the system as well as gain a greater understanding of how it works underneath. My environment is Windows XP, MySQL latest stable, phpmyadmin.

  • Virtual machine won't connect to networking interface

    - by Keyo
    I have moved my virtual box hard drive (.vdi file) from windows7 on a laptop, to windows7 on a desktop. No big deal I thought. The OS is ubuntu 10.10. Now networking is broken. I don't have a solid understanding of windows networking, maybe someone can help. Anyway, the networking no longer works. I've tried to setup eth0. I have virtualbox setup in bridge mode, my wifi connection on windows to an intel card on the virtualbox side. I think it might be something to do with windows not allowing the connection to bridge properly (security issues). I've provided some screenshots, which will hopefully help.

  • How can I use a batch shortcut to open multiple Windows Explorer folders, and a Notepad file?

    - by ModelHX
    I've recently built a computer with an SSD in it (my first) and am in the process of moving a select few of my Steam games to the SSD and symbolically linking them to where they're supposed to be on the main (mechanical) hard drive so that Steam doesn't throw a fit and I get maximum performance. To this end, I'm finding myself repeatedly navigating to both target folders to move the relevant files and opening a specific Notepad file to enter the relevant paths into a template I've got set up that I paste into the Windows command prompt to create the symlink. This is annoying. I've read up a little bit on batch shortcuts, and have a basic understanding on how to use one to open programs and files. However, I'm finding a lot of confusing suggestions on how to use batch shortcuts to open specific folders in Windows Explorer, and none of them deal with opening multiple folders at once. Any assistance on writing the shortcut would be greatly appreciated. Thank you for your time.

  • AStar in a specific case in C#

    - by KiTe
    Hello. To an intership, I have use the A* algorithm in the following case : the unit shape is a square of height and width of 1, we can travel from a zone represented by a rectangle from another, but we can't travel outside these predifined areas, we can go from a rectangle to another through a door, represented by a segment on corresponding square edge. Here are the 2 things I already did but which didn't satisfied my boss : 1 : I created the following classes : -a Door class which contains the location of the 2 separated squares and the door's orientation (top, left, bottom, right), -a Map class which contains a door list, a rectangle list representing the walkable areas and a 2D array representing the ground's squares (for additionnal infomations through an enumeration) - classes for the A* algorithm (node, AStar) 2 : -a MapCase class, which contains information about the case effect and doors through an enumeration (with [FLAGS] attribute set on, to be able to cummulate several information on each case) -a Map classes which only contains a 2D array of MapCase classes - the classes for the A* algorithm (still node an AStar). Since the 2 version is better than the first (less useless calculation, better map classes architecture), my boss is not still satisfied about my mapping classes architecture. The A* and node classes are good and easily mainainable, so I don't think I have to explain them deeper for now. So here is my asking : has somebody a good idea to implement the A* with the problem specification (rectangle walkable but with a square unit area, travelling through doors)? He said that a grid vision of the problem (so a 2D array) shouldn't be the correct way to solve the problem. I wish I've been clear while exposing my problem .. Thanks KiTe

  • http proxy caching headers

    - by David Hagan
    I have a service for which I'm about to upgrade the authentication. However, I'm trying to ensure that I make the right decision about where the encryption algorithms occur. I currently have two options: option 1) the authentication module is deployed to the client as a javascript library over https and executes client-side, so that the client can POST back an encrypted string. option 2) the authentication module is kept server-side so that the client need only POST back an unencrypted string. I know that many http proxies cache/log the query-string (and therefore any query parameters), but does anyone know of any http proxies that cache the headers as well? If the headers are being cached, then I'll clearly want to encrypt the password inside the SSL encryption, because to my understanding the headers of an HTTPS request may not always be encrypted (depending on the capabilities of the browser etcetera). Can anyone shed any light on the caching of headers by http proxies? Do you have one that does, or know of one that does?

  • Windows Server 2012 and Ubuntu 12.04.1 under Hyper-V

    - by Technicolour
    I've set up an instance of Ubuntu 12.04.1 LTS under Hyper-V 2012. However it seems to be nondeterministic as to whether or not it completes the boot process. I get a Kernel Panic, "IO-APIC + timer doesn't work!", which from my research is caused by not having integration services correctly installed? It was my understanding that the integration services were all now baked into the kernel? It should then be fine to update the OS (including any kernel updates, as I'm guessing that's what has happened) Being able to rely on this successfully booting would be great as I intend on using ssh for crisis situations.

  • Server 2008 Hard Faults

    - by claw
    Hey all, plase bear with me as I haven't looked at a server in a very long time. The problem I am having is with a Windows 2008 Standard FE Service Pack 2 Intel Xeon X3430 @ 2.40 2.39 GHZ 4 GB Memory 64 Bit There seems to be no problems other than the physical memory peaking at 91%, always with over 100 Hard Faults Per Second. To my understanding hard faults should be fairly rare on a machine with. Are there any logs I can show you? Or investigate myself. The general performance of the machine is ok, i can access SBS2008 and change settings fairly smoothly without hangs etc. However, we connect to the server and do quite a bit of SQL via an application. For a record to retrieve say 20 rows, it can take 20+ seconds. Thanks in advance, Jamie EDIT: What the server is used for: IIS ASP Web Service SQL 2008 List item Exchange unable to upload screenshots due to low reputation - why doesnt my SO work here :)
