• I work on local copies of files and upload them to a remote server on save. What version control sys

  - by 10goto10

  Here's my situation: My files are on a remote server (Linux). When I want to edit a file at home on my Windows machine, my editor (PSPad) downloads a copy. When I save the document, my editor uploads it to the server, overwriting the previous version. Is there a version control system, preferably GUI driven, that can handle this situation? Additional info: I probably can't install elaborate software on the remote server, but can on my own computer. Concurrent Versions System (CVS) is installed on the remote server. Uploading/downloading goes through an FTP-to-SFTP bridge set up with Bitvise Tunnelier.

• How to embed a web browser control in a cross-platform application?

  - by Gil

  hi, I need to write quickly this application: a simple window that wraps a web browser control, that runs html pages. The Browser UI (e.g. Navigation buttons) should be suppressed. As a .net developer, I would embed the WebBrowser OCX in a Windows Form. But this has to run on Mac as well!! I found the following cross-platform candidates. Which one would you choose (in terms of simplicity, stableness, community support, etc.): 1) wxWidgets (www.kirix.com/labs/wxwebconnect.html) 2) QT: www.youtube.com/watch?v=Ee8eRwjbcFk&feature=related 3) MONO: www.mono-project.com/WebBrowser Thanks!

• Is there a "dual user check-in" source control system?

  - by Zubair

  Are there any source control systems that require another user to validate the source code "before" it can be checked-in? I want to know as this is one technique to make sure that code quality is high. Update: There has been talk of "Branches" in the answers, and while I feel branches have there place I think that branchs are something different as when a developer's code is ready to go into the main branch it "should" be checked. Most often though I see that when this happens a lead developer or whoever is responsible for the merge into the main branch/stream just puts the code into the main branch as long as it "compiles" and does no more checks than that. I want the idea of two people putting their names to the code at an early stage so that it introduces some responsibility, and also because the code is cheaper to fix early on and is also fresh in the developers mind.

• How would you use version control for personal data, like a personal website?

  - by nn

  This is more a use-case question, but I generate static files for a personal website using txt2tags. I was thinking of maybe storing this information in a git repository. Normally I use RCS since it's simplest, and I'm only a single user. But there just seems to be a large trend of people using git/svn/cvs/etc. for personal data, and I thought this may also be a good way to at least learn some of the basics of the tool. Obviously most of the learning is done in an environment where you collaborate. So back to the question: how would you use use a version control system such as git, to manage a personal website?

• What are the merits of using the various VCS (Version Control Systems) that exist to track Drupal pr

  - by ZoFreX

  I'm trying to find the best version control strategy for my workflow with Drupal. I have multiple sites per install and I'm pretty sure I'll have a separate repository for each website. As far as I know, the VCSs worth considering are: SVN Bazaar (bzr) Git Mercurial (hg) I know how these compare to each other in general, but want to learn their merits/demerits for Drupal. If you're using (or have used) any of these for Drupal: What is your setup? What about the VCS you chose works well for managing Drupal projects? What doesn't?

  - by sunpech

  What is the difference between uninstalling a program through Control Panel, and uninstalling via the Program's uninstall.exe? Example: C:\Program Files (x86)\Notepad++\uninstall.exe In general, I read that it's better to uninstall a program via window's Control Panel. But for the programs that have their own uninstall.exe, is there any real difference between the un-installations? Is the Control Panel's cleaner in removing dependencies?

• Basic IP address structure

  - by dannymcc

  We currently have a few servers, around 30-40 workstations and 16 phones. Each device has a static IP address. As an example the standard settings for a new workstation is; IP: 192.168.1.XXX Subnet: 255.255.255.0 Gateway: 192.168.1.99 DNS: 192.168.1.50 As I am slowly exploring new server OS's and virtualisation etc. I am getting close to wanting a wider range of IP addresses. What I would like to do is seperate the devices by IP as follows: Servers 192.168.1.XXX Workstations 192.168.2.XXX Printers 192.168.3.XXX Phones 192.168.4.XXX VM's 192.168.5.XXX Is this a bad idea, or is this a common way of doing things? My biggest concern is the phones and subnet masks. The phones are managed by our provider although I have access to the server that runs them. Would I need to change the subnet mask to 255.255.0.0 on all devices? Or only those that change? For example, the phones don't need to connect to any other devices other than other phones and the phone server. So if I have the phones on 192.168.1.XXX with a subnet mask of 255.255.255.0 and then moved everything I had complete ownership/control of to 192.168.X.XXX with a new subnet mask of 255.255.0.0. Would that work?

• Control-Backspace (unix-kill-rubout) for readline?

  - by Xepoch

  In readline(3) I should be able to map Control-Backspace to the same function as Control-W (unix-kill-rubout). Regardless of what I put in ~/.inputrc I'm unable to get this to be recognized. \C-\b: unix-kill-rubout ...for instance does not work. Can I map Control-Backspace to the unix-kill-rubout in readline?

• Shaping outbound Traffic to Control Download Speeds with Linux

  - by Kyle Brandt

  I have a situation where a server makes lots of requests from big webservers all at the same time. Currently, I have not control over the amount of requests or the rate of the requests from the application that does this. The responses from these webservers is more than the internet line can handle. (Basically, we are launching a DoS on ourselves). I am going to get push to get this fixed at the application level, but for the time being, is there anyway I can use traffic shaping on the Linux server to control this? I know I can only shape outbound traffic, but maybe there is a way I can slow the TCP responses so the other side will detect congestion and this will help my situation? If there is anything like this with tc, what might the configuration look like? The idea is that the traffic control might help me control which packets get dropped before they reach my router.

• Remap control key in gnome-terminal?

  - by Colin

  I just installed Ubuntu to get more familiar with it since I'll be using it in a new job shortly. I use Macs at home and in my current job, so I'd like to make it as Mac-like as possible. I've remapped the command and control characters using the following .xmodmap: remove control = Control_L Control_R remove mod4 = Super_L Super_R add control = Super_L Super_R add mod4 = Control_L Control_R Which works great for everything except the terminal, since Ctrl-C is now mapped to CMD-C, and still conflicts with what I'd like to use to copy. Is there any way I can remap the Control key just for the terminal? I'm willing to consider gnome-terminal alternatives if required.

• Structuring Access Control In Hierarchical Object Graph

  - by SB2055

  I have a Folder entity that can be Moderated by users. Folders can contain other folders. So I may have a structure like this: Folder 1 Folder 2 Folder 3 Folder 4 I have to decide how to implement Moderation for this entity. I've come up with two options: Option 1 When the user is given moderation privileges to Folder 1, define a moderator relationship between Folder 1 and User 1. No other relationships are added to the db. To determine if the user can moderate Folder 3, I check and see if User 1 is the moderator of any parent folders. This seems to alleviate some of the complexity of handling updates / moved entities / additions under Folder 1 after the relationship has been defined, and reverting the relationship means I only have to deal with one entity. Option 2 When the user is given moderation privileges to Folder 1, define a new relationship between User 1 and Folder 1, and all child entities down to the grandest of grandchildren when the relationship is created, and if it's ever removed, iterate back down the graph to remove the relationship. If I add something under Folder 2 after this relationship has been made, I just copy all Moderators into the new Entity. But when I need to show only the top-level Folders that a user is Moderating, I need to query all folders that have a parent folder that the user does not moderate, as opposed to option 1, where I just query any items that the user is moderating. Thoughts I think it comes down to determining if users will be querying for all parent items more than they'll be querying child items... if so, then option 1 seems better. But I'm not sure. Is either approach better than the other? Why? Or is there another approach that's better than both? I'm using Entity Framework in case it matters.

• ASP.NET and WIF: Showing custom profile username as User.Identity.Name

  - by DigiMortal

  I am building ASP.NET MVC application that uses external services to authenticate users. For ASP.NET users are fully authenticated when they are redirected back from external service. In system they are logically authenticated when they have created user profiles. In this posting I will show you how to force ASP.NET MVC controller actions to demand existence of custom user profiles. Using external authentication sources with AppFabric Suppose you want to be user-friendly and you don’t force users to keep in mind another username/password when they visit your site. You can accept logins from different popular sites like Windows Live, Facebook, Yahoo, Google and many more. If user has account in some of these services then he or she can use his or her account to log in to your site. If you have community site then you usually have support for user profiles too. Some of these providers give you some information about users and other don’t. So only thing in common you get from all those providers is some unique ID that identifies user in service uniquely. Image above shows you how new user joins your site. Existing users who already have profile are directed to users homepage after they are authenticated. You can read more about how to solve semi-authorized users problem from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages. The other problem is related to usernames that we don’t get from all identity providers. Why is IIdentity.Name sometimes empty? The problem is described more specifically in my blog posting Identifying AppFabric Access Control Service users uniquely. Shortly the problem is that not all providers have claim called http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name. The following diagram illustrates what happens when user got token from AppFabric ACS and was redirected to your site. Now, when user was authenticated using Windows Live ID then we don’t have name claim in token and that’s why User.Identity.Name is empty. Okay, we can force nameidentifier to be used as name (we can do it in web.config file) but we have user profiles and we want username from profile to be shown when username is asked. Modifying name claim Now let’s force IClaimsIdentity to use username from our user profiles. You can read more about my profiles topic from my blog posting ASP.NET MVC: Using ProfileRequiredAttribute to restrict access to pages and you can find some useful extension methods for claims identity from my blog posting Identifying AppFabric Access Control Service users uniquely. Here is what we do to set User.Identity.Name: we will check if user has profile, if user has profile we will check if User.Identity.Name matches the name given by profile, if names does not match then probably identity provider returned some name for user, we will remove name claim and recreate it with correct username, we will add new name claim to claims collection. All this stuff happens in Application_AuthorizeRequest event of our web application. The code is here. protected void Application_AuthorizeRequest() {     if (string.IsNullOrEmpty(User.Identity.Name))     {         var identity = User.Identity;         var profile = identity.GetProfile();         if (profile != null)         {             if (profile.UserName != identity.Name)             {                 identity.RemoveName();                   var claim = new Claim("http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name", profile.UserName);                 var claimsIdentity = (IClaimsIdentity)identity;                 claimsIdentity.Claims.Add(claim);             }         }     } } RemoveName extension method is simple – it looks for name claims of IClaimsIdentity claims collection and removes them. public static void RemoveName(this IIdentity identity) {     if (identity == null)         return;       var claimsIndentity = identity as ClaimsIdentity;     if (claimsIndentity == null)         return;       for (var i = claimsIndentity.Claims.Count - 1; i >= 0; i--)     {         var claim = claimsIndentity.Claims[i];         if (claim.ClaimType == "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name")             claimsIndentity.Claims.RemoveAt(i);     } } And we are done. Now User.Identity.Name returns the username from user profile and you can use it to show username of current user everywhere in your site. Conclusion Mixing AppFabric Access Control Service and Windows Identity Foundation with custom authorization logic is not impossible but a little bit tricky. This posting finishes my little series about AppFabric ACS and WIF for this time and hopefully you found some useful tricks, tips, hacks and code pieces you can use in your own applications.

• IRM and Consumerization

  - by martin.abrahams

  As the season of rampant consumerism draws to its official close on 12th Night, it seems a fitting time to discuss consumerization - whereby technologies from the consumer market, such as the Android and iPad, are adopted by business organizations. I expect many of you will have received a shiny new mobile gadget for Christmas - and will be expecting to use it for work as well as leisure in 2011. In my case, I'm just getting to grips with my first Android phone. This trend developed so much during 2010 that a number of my customers have officially changed their stance on consumer devices - accepting consumerization as something to embrace rather than resist. Clearly, consumerization has significant implications for information control, as corporate data is distributed to consumer devices whether the organization is aware of it or not. I daresay that some DLP solutions can limit distribution to some extent, but this creates a conflict between accepting consumerization and frustrating it. So what does Oracle IRM have to offer the consumerized enterprise? First and foremost, consumerization does not automatically represent great additional risk - if an enterprise seals its sensitive information. Sealed files are encrypted, and that fundamental protection is not affected by copying files to consumer devices. A device might be lost or stolen, and the user might not think to report the loss of a personally owned device, but the data and the enterprise that owns it are protected. Indeed, the consumerization trend is another strong reason for enterprises to deploy IRM - to protect against this expansion of channels by which data might be accidentally exposed. It also enables encryption requirements to be met even though the enterprise does not own the device and cannot enforce device encryption. Moving on to the usage of sealed content on such devices, some of our customers are using virtual desktop solutions such that, in truth, the sealed content is being opened and used on a PC in the normal way, and the user is simply using their device for display purposes. This has several advantages: The sensitive documents are not actually on the devices, so device loss and theft are even less of a worry The enterprise has another layer of control over how and where content is used, as access to the virtual solution involves another layer of authentication and authorization - defence in depth It is a generic solution that means the enterprise does not need to actively support the ever expanding variety of consumer devices - the enterprise just manages some virtual access to traditional systems using something like Citrix or Remote Desktop services. It is a tried and tested way of accessing sealed documents. People have being using Oracle IRM in conjunction with Citrix and Remote Desktop for several years. For some scenarios, we also have the "IRM wrapper" option that provides a simple app for sealing and unsealing content on a range of operating systems. We are busy working on other ways to support the explosion of consumer devices, but this blog is not a proper forum for talking about them at this time. If you are an Oracle IRM customer, we will be pleased to discuss our plans and your requirements with you directly on request. You can be sure that the blog will cover the new capabilities as soon as possible.

• Is there a term for quasi-open source proprietary software?

  - by mwhite

  Say a company wants to keep development of new features of a piece of software internal, but wants to make the source code for previous versions public, up to and including existing public features, so that other people can benefit from using and modifying the software themselves, and even possibly contribute changes that can be applied to the development branch. Is there a term for this sort of arrangement, and what is the best way of accomplishing it using existing version control tools and platforms?

• Quick question - how to comment if-else structure?

  - by serg555

  Lets say you have: if(condition) { i = 1; } else { i = 2; } and you need to put comments explaining if and else blocks. What's the most readable way of doing it so someone can easily pick them up at first glance? I usually do it like this: //check for condition if(condition) { i = 1; } else { //condition isn't met i = 2; } which I find not good enough as comments are located at different levels, so at quick glance you would just pick up if comment and else comment would look like it belongs to some inner structure. Putting them like this: if(condition) { //check for condition i = 1; } else { //condition isn't met i = 2; } doesn't look good to me either as it would seem like the whole structure is not commented (condition might be big and take multiple lines). Something like that: //check for condition if(condition) { i = 1; //condition isn't met } else { i = 2; } would be probably the best style from comments point of view but confusing as a code structure. How do you comment such blocks?

• FIlling a Java Bean tree structure from a csv flat file

  Hi, I'm currently trying to construct a list of bean classes in Java from a flat description file formatted in csv. Concretely : Here is the structure of the csv file : MES_ID;GRP_PARENT_ID;GRP_ID;ATTR_ID M1 ; ;G1 ;A1 M1 ; ;G1 ;A2 M1 ;G1 ;G2 ;A3 M1 ;G1 ;G2 ;A4 M1 ;G2 ;G3 ;A5 M1 ; ;G4 ;A6 M1 ; ;G4 ;A7 M1 ; ;G4 ;A8 M2 ; ;G1 ;A1 M2 ; ;G1 ;A2 M2 ; ;G2 ;A3 M2 ; ;G2 ;A4 It corresponds to the hierarchical data structure : M1 ---G1 ------A1 ------A2 ------G2 ---------A3 ---------A4 ---------G3 ------------A5 ------G4 ---------A7 ---------A8 M2 ---G1 ------A1 ------A2 ---G2 ------A3 ------A4 Remarks : A message M can have an infinite number of groups G and attributes A A group G can have an infinite number of attributes and an infinite number of under-groups each of them having under-groups too That beeing said, I'm trying to read this flat csv decription to store it in this structure of beans : Map<String, MBean> messages = new HashMap<String, Mbean>(); == public class MBean { private String mes_id; private Map<String, GBean> groups; } public class GBean { private String grp_id; private Map<String, ABean> attributes; private Map<String, GBean> underGroups; } public class ABean { private String attr_id; } Reading the csv file sequentially is ok and I've been investigating how to use recursion to store the description data, but couldn't find a way. Thanks in advance for any of your algorithmic ideas. I hope it will put you in the mood of thinking about this ... I've to admit that I'm out of ideas :s

• Thread-safe data structure design

  - by Inso Reiges

  Hello, I have to design a data structure that is to be used in a multi-threaded environment. The basic API is simple: insert element, remove element, retrieve element, check that element exists. The structure's implementation uses implicit locking to guarantee the atomicity of a single API call. After i implemented this it became apparent, that what i really need is atomicity across several API calls. For example if a caller needs to check the existence of an element before trying to insert it he can't do that atomically even if each single API call is atomic: if(!data_structure.exists(element)) { data_structure.insert(element); } The example is somewhat awkward, but the basic point is that we can't trust the result of "exists" call anymore after we return from atomic context (the generated assembly clearly shows a minor chance of context switch between the two calls). What i currently have in mind to solve this is exposing the lock through the data structure's public API. This way clients will have to explicitly lock things, but at least they won't have to create their own locks. Is there a better commonly-known solution to these kinds of problems? And as long as we're at it, can you advise some good literature on thread-safe design? EDIT: I have a better example. Suppose that element retrieval returns either a reference or a pointer to the stored element and not it's copy. How can a caller be protected to safely use this pointer\reference after the call returns? If you think that not returning copies is a problem, then think about deep copies, i.e. objects that should also copy another objects they point to internally. Thank you.

• MySQL - Structure for Permissions to Objects

  - by Kerry

  What would be an ideal structure for users permissions of objects. I've seen many related posts for general permissions, or what sections a user can access, which consists of a users, userGroups and userGroupRelations or something of that nature. In my system there are many different objects that can get created, and each one has to be able to be turned on or off. For instance, take a password manager that has groups and sub groups. Group 1 Group 2 Group 3 Group 4 Group 5 Group 6 Group 7 Group 8 Group 9 Group 10 Each group can contain a set of passwords. A user can be given read, write, edit and delete permissions to any group. More groups can get created at any point in time. If someone has permission to a group, I should be able to make him have permissions to all sub groups OR restrict it to just that group. My current thought is to have a users table, and then a permissions table with columns like: permission_id (int) PRIMARY_KEY user_id (int) INDEX object_id (int) INDEX type (varchar) INDEX read (bool) write (bool) edit (bool) delete (bool) This has worked in the past, but the new system I'm building needs to be able to scale rapidly, and I am unsure if this is the best structure. It also makes the idea of having someone with all subgroup permissions of a group more difficult. So, as a question, should I use the above structure? Or can someone point me in the direction of a better one?

I think I should be using an array to achieve the above but I'm not sure how I would set it up or how to reference certain things in the array. The other question is how can I get how many times something was repeated? The URL I have no problem with. Can anyone help me out?
