  • Keeping track of dirty blocks on a block device

    - by mikeY
    I'm looking for a way to keep track of what blocks on a block device are modified after a point in time. How I eventually want to use this for is to keep two 2TB disks in sync, one which only comes online (connected through USB) once a month. Without knowing what blocks have been modified, I have to go through the whole 2TB every time. I'm using a recent GNU/Linux OS and have C and Python experience. I'm hoping to avoid writing kernel level code as I don't have any experience in that area whatsoever. My current theory is that there should be some hooks somewhere where my code can get called when a disk flush is performed. Any ideas?

  • Track each URL and Parameters sent from Form

    - by Arjun
    Simple question really for anyone who's been through this: I have a form that I'm placing on a site. This form submits some parameters to a site which then sends some parameters using "GET" to another site, which then opens the third site. Now the first 2 sites pass so quickly that I can not see what parameters were passed using the URL. I can do a manual check using source code but its too long and complex. I just need a simple tool or hint or firefox addon on how to track every single URL (wven if it has a META redirect) so I can read parameters being sent via the form. Thanks

  • Keeping track of threads when creating them recursively

    - by 66replica
    I'm currently working on some code for my Programming Languages course. I can't post the code but I'm permitted to talk about some high level concepts that I'm struggling with and receive input on them. Basically the code is a recursive DFS on a undirected graph that I'm supposed to convert to a concurrent program. My professor already specified that I should create my threads in the recursive DFS method and then join them in another method. Basically, I'm having trouble thinking of how I should keep track of the threads I'm creating so I can join all of them in the other method. I'm thinking an array of Threads but I'm unsure how to add each new thread to the array or even if that's the right direction.

  • OnClientClick event for keeping track of prints?

    - by Ram
    Hello, I am trying to keep track of prints that are made for a page. The page has Print this page link. And the code for it is like below: This is written in .cs file as there are many conditions for displaying this. And i am appending here using String Builder. sbOutput.AppendFormat("<td align=\"right\" valign=\"bottom\"><div style =\"float:right;text-align:right; valign:bottom;width:200px\"class=\"print_button notPrinted\"><a class=\"notPrinted\" href=\"#\" onclick=\"window.print();\">PRINT THIS COUPON </a><img src=\"images/print-icon-34x34.gif\" class=\"notPrinted\" align=\"absmiddle\" /></div> </td></tr></table>", couponid, Userid, locationid); Do i have to use onclientclick or something else?? Thanks so much in advance.

  • How to track down a Blue Screen of Death triggered by an (usermode) application

    - by mhenry1384
    We have a .Net application consisting of mixed managed and unmanaged code. We have a number of reports of users getting BSOD while using our application. These blue screens happen on different versions of Windows. Mostly XP but one user claims it happens on Windows 7. Some users see it happening when doing one thing, other see it happening when doing something completely different. Of course, we cannot reproduce the problem. Needless to say, I'm stumped. A user mode application shouldn't be able to blue screen the OS so we are running into a bug in a common kernel space application, perhaps buggy antivirus software? Does anyone have any tips on how to track something like this down? We don't have access to a computer where this is happening so we wouldn't be able to hook up a kernel debugger or anything like that.

  • Github + keep file but dont track changes

    - by Mike
    I have a codeigniter framework thats using github. Within this application I have several files that i will want to have in the repo but not track any changes on.. Example is: i deploy a new installation of this framework to a new client, i want the following files to be downloaded (they have default values 'CHANGEME') and i just have to make changes specific to this client IE(database credentials, email address info, custom css styling). // the production config files i want the files but they need to be updated to specific client needs application/config/production/config.php application/config/production/database.php application/config/production/tank_auth.php // index page, defines the environment (production|development) /index.php // all of the css/js cache (keep the folder but not the contents) /assets/cache/* // production user based styling (color, fonts etc) needs to be updated specific to client needs /assets/frontend/css/user/frontend-user.css currently if i run git clone [email protected]:user123/myRepo.git httpdocs and then i edit the files above, all is great.. until i release a hotfix or patch and run git pull. All of my changes are then overwritten.

  • Reattaching an object graph to an EntityContext: "cannot track multiple objects with the same key"

    - by dkr88
    Can EF really be this bad? Maybe... Let's say I have a fully loaded, disconnected object graph that looks like this: myReport = {Report} {ReportEdit {User: "JohnDoe"}} {ReportEdit {User: "JohnDoe"}} Basically a report with 2 edits that were done by the same user. And then I do this: EntityContext.Attach(myReport); InvalidOperationException: An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. Why? Because the EF is trying to attach the {User: "JohnDoe"} entity TWICE. This will work: myReport = {Report} {ReportEdit {User: "JohnDoe"}} EntityContext.Attach(myReport); No problems here because the {User: "JohnDoe"} entity only appears in the object graph once. What's more, since you can't control how the EF attaches an entity, there is no way to stop it from attaching the entire object graph. So really if you want to reattach a complex entity that contains more than one reference to the same entity... well, good luck. At least that's how it looks to me. Any comments? UPDATE: Added sample code: // Load the report Report theReport; using (var context1 = new TestEntities()) { context1.Reports.MergeOption = MergeOption.NoTracking; theReport = (from r in context1.Reports.Include("ReportEdits.User") where r.Id == reportId select r).First(); } // theReport looks like this: // {Report[Id=1]} // {ReportEdit[Id=1] {User[Id=1,Name="John Doe"]} // {ReportEdit[Id=2] {User[Id=1,Name="John Doe"]} // Try to re-attach the report object graph using (var context2 = new TestEntities()) { context2.Attach(theReport); // InvalidOperationException }

  • Keeping track of leading zeros with BitSet in Java

    - by Ryan
    So, according to this question there are two ways to look at the size of a BitSet. size(), which is legacy and not really useful. I agree with this. The size is 64 after doing: BitSet b = new BitSet(8); length(), which returns the index of the highest set bit. In the above example, length() will return 0. This is somewhat useful, but doesn't accurately reflect the number of bits the BitSet is supposed to be representing in the event you have leading zeros. The information I'm dealing with rarely(if ever) falls evenly into 8-bit bytes, and the leading 0s are just as important to me as the 1s. I have some data fields that are 333 bits long, some that are 20, etc. Is there a better way to deal with bit-level details in Java that will keep track of leading zeros? Otherwise, I'm going to have to 'roll my own', so to speak. To which I have a few ideas already, but I'd prefer not to reinvent the wheel if possible.

  • need help with C++ using maps to keep track of words in a INPUT file

    - by eNetik
    Let say i have a text file with today is today but tomorrow is today tomorrow then using maps how can i keep track of the words that are repeated? and on which line it repeats? so far i have each string in the file read in as a temp and it is stored in the following way: map<string,int> storage; int count = 1 // for the first line of the file if(infile.is_open()){ while( !infile.eof() ){ getline(in, line); istringstream my_string(line); while(my_string.good()){ string temp; my_string >> temp; storage[temp] = count } count++;// so that every string read in the next line will be recorded as that line. } } map<string,int>::iterator m; for(int m = storage.begin(); m!= storage.end(); m++){ out<<m->first<<": "<<"line "<<m->second<<endl; } right now the output is just but: line 1 is: line 2 today: line 2 tomorrow: line 2 But instead.. it should print out(no repeating strings): today : line 1 occurred 2 times, line 2 occurred 1 time. is: line 1 occurred 1 time, line 2 occurred 1 time. but: line 1 occurred 1 time. tomorrow: line 2 occurred 2 times. Note: the order of the string does not matter. Any help would be appreciated. Thanks.

  • How to track deleted self-tracking entities in ObservableCollection without memory leaks

    - by Yannick M.
    In our multi-tier business application we have ObservableCollections of Self-Tracking Entities that are returned from service calls. The idea is we want to be able to get entities, add, update and remove them from the collection client side, and then send these changes to the server side, where they will be persisted to the database. Self-Tracking Entities, as their name might suggest, track their state themselves. When a new STE is created, it has the Added state, when you modify a property, it sets the Modified state, it can also have Deleted state but this state is not set when the entity is removed from an ObservableCollection (obviously). If you want this behavior you need to code it yourself. In my current implementation, when an entity is removed from the ObservableCollection, I keep it in a shadow collection, so that when the ObservableCollection is sent back to the server, I can send the deleted items along, so Entity Framework knows to delete them. Something along the lines of: protected IDictionary<int, IList> DeletedCollections = new Dictionary<int, IList>(); protected void SubscribeDeletionHandler<TEntity>(ObservableCollection<TEntity> collection) { var deletedEntities = new List<TEntity>(); DeletedCollections[collection.GetHashCode()] = deletedEntities; collection.CollectionChanged += (o, a) => { if (a.OldItems != null) { deletedEntities.AddRange(a.OldItems.Cast<TEntity>()); } }; } Now if the user decides to save his changes to the server, I can get the list of removed items, and send them along: ObservableCollection<Customer> customers = MyServiceProxy.GetCustomers(); customers.RemoveAt(0); MyServiceProxy.UpdateCustomers(customers); At this point the UpdateCustomers method will verify my shadow collection if any items were removed, and send them along to the server side. This approach works fine, until you start to think about the life-cycle these shadow collections. Basically, when the ObservableCollection is garbage collected there is no way of knowing that we need to remove the shadow collection from our dictionary. I came up with some complicated solution that basically does manual memory management in this case. I keep a WeakReference to the ObservableCollection and every few seconds I check to see if the reference is inactive, in which case I remove the shadow collection. But this seems like a terrible solution... I hope the collective genius of StackOverflow can shed light on a better solution. Thanks!

  • Keeping track of business rules within IT department?

    - by evaldas-alexander
    I am looking for the best way to keep track of the business rules for both developers and everybody else (support staff / management) in a startup enviroment. The challenge is that our business model requires quite a lot of different business rules, which are created pretty much on the fly and evolving organically after that. After running this project for 3+ years, we have so many of such rules that often the only way to be sure about what the application is supposed to do in a certain situation is to go find the module responsible for that process and analyze its code and comments. That is all fine as long as you have one single developer who created the entire application from the scratch, but every new developer needs to go over pretty much entire codebase in order to understand how the application works. Even bigger problem is that non technical employees don't even have that option and therefore are forced to ask me pretty much every day how some certain case would be handled by the application. Quick example - we only start charging for our customer campaigns once they have been active for at least 72 hours, but at the same time we stop creating invoices for campaigns that belong to insolvent accounts and close such accounts within a month of the first failed charge. That does not apply to accounts that are set to "non-chargeable" which most commonly belongs to us since we are using the service ourselves. The invoices are created on the 1st of each month and include charges from the previous month + any current balance that the account might have. However, some customers are charged only 4 days after their invoice has been generated due to issues with their billing department. In addition to that, invoices are also created when customer deactivates his campaign, but that can only be done once the campaign is not longer under mandatory 6 month contract, unless account manager approves early deactivation. I know, that's quite a lot of rules that need to be taken into account when answering a question "when do we bill our customers", but actually I could still append an asterisk at the end of each sentence in order to disclose some rare exceptions. Of course, it would be easiest just to keep the business rules to the minimum, but we need to adapt to changing marketplace - i.e. less than a year ago we had no contracts whatsoever. One idea that I had so far was a simplistic wiki with categories corresponding to areas such as "Account activation", "Invoicing", "Collection procedures" and so on. Another idea would be to have giant interactive flowchart showing the entire customer "life cycle" from prospecting to account deactivation. What are your experiences / suggestions?

  • How can I track hits to areas of my web application?

    - by Tyson
    We have a growing web application, and we currently use Google Analytics and Chartbeat to track usage and engagement (although we're open to alternatives). Unfortunately, both are geared towards content-based sites where everything is about the URL. Our URLs contain object IDs, making them less useful independently, and causing us to grow beyond Google Analytics' 50,000 unique URLs per day. How can we track hits to areas of our web application, essentially ignoring parts of the URLs?

  • How do they keep track of the NPCs in Left 4 Dead?

    - by f20k
    How do they keep track of the NPC zombies in Left 4 Dead? I am talking about the NPCs that just walk into walls or wander around aimlessly. Even though the players cannot see them, they are there (say inside rooms or behind doors). Let's say there's about 10 or so zombies in a hallway and inside rooms. Does the game keep all of those zombies in a list and iterate through giving them commands? Do they just spawn when the user is within a certain radius or reached a special location? Say you placed the 4 units (controlled by players) on completely different places throughout the map. Let's assume you aren't being swarmed and then you have not killed any of these aimless NPCs. Would the game be keeping track of 10 x 4 = 40 zombies in total? Or is my understanding completely off? The reason I ask is if I were to implement something similar on a mobile device, keeping track of 40 or more NPCs might not be such a great idea.

  • How to keep track of user images when using a CDN? [closed]

    - by Programmer
    We are considering moving our user profile images from the local server to the Rackspace CDN (Cloud Files). However, how do you keep track of where each user's profile image is located on the CDN? Wouldn't you have to store the CDN URL for each user image in the local Database and query it every time you display a user image? Isn't that slower than accessing a user image directly on the local server which requires no such DB query to retrieve since you already know where it is stored based on the user's User ID? What if a user has an album of pics? How would you keep track of all those images that belong just to that one user? What about the order of those pics? In the case of the Rackspace CDN, we're looking at using a Container for each individual user to help keep things more logically organized, but we don't know what the best way to track all of it is since the CDN provides a seemingly random URL for each image. To make matters worse, you can't even delete a non-empty Container belonging to a user when they delete their account, you actually have to delete each object inside the Container one-by-one before deleting the Container itself. It doesn't end there, you can't even have nested Containers or "sub-folders", and you can't rename a file (you must copy it with a new name and delete the old one manually). It just sounds so incredibly more complicated then we thought it would be, and it certainly does not feel "intuitive" compared to local storage, so we don't know what to do. Please help.

  • How to track humans, but not spiders?

    - by johnnietheblack
    I am writing a nice little PHP/MySQL/JS ad system for my site - charging by impression. Therefore, my clients would like to be sure that they aren't paying for impressions caused by robots / spiders / etc. Is there a decently effective way to decipher between human and robot, without doing something obstructive like a captcha, or requesting "no index" or something? Basically, is there some sort of "name tag" that legit spiders have on so that my site knows their presence, therefore letting me react accordingly? And, if there isn't...how do ad companies like Google defend against this?

  • Block Google requests to 16k using pf firewall

    - by atmosx
    I'd like to block access to Google search using PF after the threshold of 17500 requests (connection established) in 24h, from a host running FreeBSD 9. What I came up with, after reading pf-faq is this rule: pass out on $net proto tcp from any to 'www.google.com' port www flags S/SA keep state (max-src-conn 200, max-src-conn-rate 17500/86400) NOTE: 86400 are 24h in seconds. The rule should work, but PF is smart enough to know that www.google.com resolves in 5 different IPs. So my pfctl -sr output gives me this: pass out on vte0 inet proto tcp from any to 173.194.44.81 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.82 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.83 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.80 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) pass out on vte0 inet proto tcp from any to 173.194.44.84 port = http flags S/SA keep state (source-track rule, max-src-conn 200, max-src-conn-rate 17500/86400, src.track 86400) PF creates 5 different rules, 1 for each IP that Google resolves. However I have the sense - without being 100% sure, I didn't had the chance to test it - that the number 17500/86400 applies for each IP. If that's the case - please confirm - then it's not what I want. In pf-faq there's another option called source-track-global: source-track This option enables the tracking of number of states created per source IP address. This option has two formats: + source-track rule - The maximum number of states created by this rule is limited by the rule's max-src-nodes and max-src-states options. Only state entries created by this particular rule count toward the rule's limits. + source-track global - The number of states created by all rules that use this option is limited. Each rule can specify different max-src-nodes and max-src-states options, however state entries created by any participating rule count towards each individual rule's limits. The total number of source IP addresses tracked globally can be controlled via the src-nodes runtime option. I tried to apply source-track-global in the above rule without success. How can I use this option in order to achieve my goal? Any thoughts or comments are more than welcome since I'm an amateur and don't fully understand PF yet. Thanks

  • Track "commands" send to WPF window by touchpad (Bamboo)

    - by Christian
    Hi, I just bought a touchpad wich allows drawing and using multitouch. The api is not supported fully by windows 7, so I have to rely on the build in config dialog. The basic features are working, so if I draw something in my WPF tool, and use both fingers to do a right click, I can e.g. change the color. What I want to do now is assign other functions to special features in WPF. Does anybody know how to find out in what way the pad communicates with the app? It works e.g. in Firefox to scroll, like it should (shown on this photo). But I do not know how to hookup the scroll event, I tried a Scrollviewer (which ignores my scroll attempts) and I also hooked up an event with the keypressed, but it does not fire (I assume the pad does not "press a key" but somehow sends the "scroll" command direclty. How can I catch that command in WPF? Thanks a lot, Chris [EDIT] I got the scroll to work, but only up and down, not left and right. It was just a stupid "listbox in scrollviewer" mistake. But still not sure about commands like ZOOM in (which is working even in paint).. Which API contains such things? [EDIT2] Funny, the zoom works in Firefox, the horizontal scrolling does not. But, in paint, the horizontal scrolling works... [EDIT 3] Just asked in the wacom forum, lets see about vendor support reaction time... http://forum.wacom.eu/viewtopic.php?f=4&t=1939 Here is a picture of the config surface to get the idea what I am talking about: (Bamboo settings, I try to catch these commands in WPF)

  • Facebook Graph API authentication in canvas app and track session

    - by cdpnet
    Short question is: how can i use graph api oauth redirects mechanism to authenticate user and save retrieved access_token and also use javascript SDK when needed (the problem is javascript SDK will have different access_token when initialized). I have initially setup my facebook iframe canvas app, with single sign on. This works well with graph api, as I am able to use access_token saved by facebook's javascript when it detects sessionchange(user logged in). But, I want to rather not do single sign-on. But, use graph api redirect and force user to send to a permissions dialog. But, if he has already given permissions, I shouldn't redirect user. How to handle this? Another question: I have done graph api redirects for authentication and have retrieved access_token also. But then, what if I want to use javascript call FB.ui to do stream.Publish? I think it will use it's own access_token which is set during FB.init and detecting session. So, I am looking for some path here. How to use graph api for authentication and also use facebook's javascript SDK when needed. P.S. I'm using ASP .NET MVC 2. I have an authentication filter developed, which needs to detect the user's authentication state and redirect.(currently it does this to graph api authorize url)
