  • User accounts in FTP

    - by Brad
    I have an FTP server(proftpd on debian) that I'm going to allow a couple friends access to, and I want some safety nets in place, just in case. These are some of the things I'd like to do: Jail the accounts to their home directories and impose a cap on the amount of data they can upload Allow them access to a shared folder(via symlink or something) where they have full access(Also with a storage cap, but larger) Allow my own account full access to the system(Using groups I guess) Not allow anonymous access, or allow it with its own folder, separate from the shared user folder Currently, I've got the accounts set up and jailed, but it seems like the symlink that I put in is not allowing them to visit the shared folder. I suppose this has to do with them not having read permissions anywhere but their own home directories, or maybe it's something else, I'll continue to look into it and provide any information that is requested. Is what I'm trying to do possible? Any tips or resources that you can share are appreciated. Thanks.

  • Uses of persistent data structures in non-functional languages

    - by Ray Toal
    Languages that are purely functional or near-purely functional benefit from persistent data structures because they are immutable and fit well with the stateless style of functional programming. But from time to time we see libraries of persistent data structures for (state-based, OOP) languages like Java. A claim often heard in favor of persistent data structures is that because they are immutable, they are thread-safe. However, the reason that persistent data structures are thread-safe is that if one thread were to "add" an element to a persistent collection, the operation returns a new collection like the original but with the element added. Other threads therefore see the original collection. The two collections share a lot of internal state, of course -- that's why these persistent structures are efficient. But since different threads see different states of data, it would seem that persistent data structures are not in themselves sufficient to handle scenarios where one thread makes a change that is visible to other threads. For this, it seems we must use devices such as atoms, references, software transactional memory, or even classic locks and synchronization mechanisms. Why then, is the immutability of PDSs touted as something beneficial for "thread safety"? Are there any real examples where PDSs help in synchronization, or solving concurrency problems? Or are PDSs simply a way to provide a stateless interface to an object in support of a functional programming style?

  • Lenovo Ideapad Unstable Touchpad Cursor

    - by vicban3d
    I recently installed Ubuntu 14.04 on my Lenovo Yoga 2 Pro and there is a problem with the touchpad. Whenever I lift my finger from the touchpad or click, the cursor moves a little bit to a random direction which makes me miss the target I wanted to click. This is very annoying and I couldn't find a solution online. Can anyone tell me whether there is a solution to this problem and how would I fix it? Thanks in advance.

  • DB auto failover in c# does not work when the principal server physically goes offline

    - by user62521
    I'm setting up DB auto failover in C# with SQL Server 2008 and I have a 'high safety with automatic failover mirror' using a witness setup and my connection string looks like "Server=tcp:DC01; Failover Partner=tcp:DC02; database=dbname; uid=sewebsite;pwd=somerndpwd;Connect Timeout=10;Pooling=True;" During testing, when I turn off the SQL Server service on the principal server the auto failover works like a charm, but if I take the principal server offline (by shutting down the server or killing the network card) auto failover does not work and my website just times out. I found this article where the second last post suggests that its because we are using named pipes which does not work when the principal goes offline, but we force TCP in our connection string. What am I missing to get this DB auto failover working?

  • Oracle Solutions supporting ICAM deployments

    - by user12604761
    The ICAM architecture has become the predominant security architecture for government organizations.  A growing number of federal, state, and local organizations are in various stages of using Oracle ICAM solutions.  The relevance of ICAM has clearly extended beyond the Federal ICAM mandates to any government program that must enable standards based interoperability like health exchanges and public safety.  The state government endorsed version of ICAM was just released with the NASCIO SICAM Roadmap. ICAM solutions require an integrated security architecture.  The major new release in August of Oracle Identity Management 11gR2 focuses on a platform approach to identity management.  This makes it easier for government organizations to acquire and implement a comprehensive ICAM solution, rather than individual products.  The following analysts reports describe the value of the Oracle Solutions: According to The Aberdeen Group:  “Organizations can save up to 48% deploying a platform of  (identity management) solutions when compared to deploying point solutions” IDC Product Flash, July 2012:  “Oracle may have hit the home run grand slam in identity management recently with the announcement of Oracle Identity Management 11g R2." For additional information on the Oracle ICAM solutions, attend the Webcast on October 10, 2012:  ICAM Framework for Enabling Agile, Service Delivery. Visit the Oracle Secure Government Resource Center for information on enterprise security solutions that help government safeguard information, resources and networks.

    I want to sell software online and I need an easy to implement payment processing system. What I'm actually going to be selling is an activation code (one per purchase) that would activate the trial version of a product. I was about to use this one but I just found out that people without a paid email account (not hotmail or yahoo) can't process their orders, which I'm sure would discourage many, if not most, of the possible buyers.
