  • Triggering an action when a specific volume is connected

    - by ereOn
    I have a USB key that contains my keepass2 password database and I'd like to perform some actions when it is plugged into my computer, namely: Auto-mount it to some specific location When the mounting is done properly, launching keepass2 on the password database file Simple tasks I guess, but I can't find how to do that. I'm using Ubuntu 12.10, and it auto-mounts the device as a "media usb-key" and tries to open the images on it (even though there are none). What is the best way to do that and to disable the ubuntu auto-mounting (so it doesn't conflict) ?

  • #OOW 2012 @PARIS...talking Oracle and Clouds, and Optimized Datacenter

    - by Eric Bezille
    For those of you who want to get most out of Oracle technologies to evolve your IT to the Next Wave, I encourage you to register to the up coming Oracle Optimized Datacenter event that will take place in Paris on November 28th. You will get the opportunity to exchange with Oracle experts and customers having successfully evolve their IT by leveraging Oracle technologies. You will also get the latest news on some of the Oracle systems announcements made during OOW 2012. During this event we will make an update about Oracle and Clouds, from private to public and hybrid models. So in preparing this session, I thought it was a good start to make a status of Cloud Computing in France, and CIO requirements in particular. Starting in 2009 with the first Cloud Camp in Paris, the market has evolved, but the basics are still the same : think hybrid. From Traditional IT to Clouds One size doesn't fit all, and for big companies having already an IT in place, there will be parts eligible to external (public) cloud, and parts that would be required to stay inside the firewalls, so ability to integrate both side is key.  None the less, one of the major impact of Cloud Computing trend on IT, reported by Forrester, is the pressure it makes on CIO to evolve towards the same model that end-users are now used to in their day to day life, where self-service and flexibility are paramount. This is what is driving IT to transform itself toward "a Global Service Provider", or for some as "IT "is" the Business" (see : Gartner Identifies Four Futures for IT and CIO), and for both models toward a Private Cloud Service Provider. In this journey, there is still a big difference between most of existing external Cloud and a firm IT : the number of applications that a CIO has to manage. Most cloud providers today are overly specialized, but at the end of the day, there are really few business processes that rely on only one application. So CIOs has to combine everything together external and internal. And for the internal parts that they will have to make them evolve to a Private Cloud, the scope can be very large. This will often require CIOs to evolve from their traditional approach to more disruptive ones, the time has come to introduce new standards and processes, if they want to succeed. So let's have a look at the different Cloud models, what type of users they are addressing, what value they bring and most importantly what needs to be done by the  Cloud Provider, and what is left over to the user. IaaS, PaaS, SaaS : what's provided and what needs to be done First of all the Cloud Provider will have to provide all the infrastructure needed to deliver the service. And the more value IT will want to provide, the more IT will have to deliver and integrate : from disks to applications. As we can see in the above picture, providing pure IaaS, left a lot to cover for the end-user, that’s why the end-user targeted by this Cloud Service is IT people. If you want to bring more value to developers, you need to provide to them a development platform ready to use, which is what PaaS is standing for, by providing not only the processors power, storage and OS, but also the Database and Middleware platform. SaaS being the last mile of the Cloud, providing an application ready to use by business users, the remaining part for the end-users being configuring and specifying the application for their specific usage. In addition to that, there are common challenges encompassing all type of Cloud Services : Security : covering all aspect, not only of users management but also data flows and data privacy Charge back : measuring what is used and by whom Application management : providing capabilities not only to deploy, but also to upgrade, from OS for IaaS, Database, and Middleware for PaaS, to a full Business Application for SaaS. Scalability : ability to evolve ALL the components of the Cloud Provider stack as needed Availability : ability to cover “always on” requirements Efficiency : providing a infrastructure that leverage shared resources in an efficient way and still comply to SLA (performances, availability, scalability, and ability to evolve) Automation : providing the orchestration of ALL the components in all service life-cycle (deployment, growth & shrink (elasticity), upgrades,...) Management : providing monitoring, configuring and self-service up to the end-users Oracle Strategy and Clouds For CIOs to succeed in their Private Cloud implementation, means that they encompass all those aspects for each component life-cycle that they selected to build their Cloud. That’s where a multi-vendors layered approach comes short in terms of efficiency. That’s the reason why Oracle focus on taking care of all those aspects directly at Engineering level, to truly provide efficient Cloud Services solutions for IaaS, PaaS and SaaS. We are going as far as embedding software functions in hardware (storage, processor level,...) to ensure the best SLA with the highest efficiency. The beauty of it, as we rely on standards, is that the Oracle components that you are running today in-house, are exactly the same that we are using to build Clouds, bringing you flexibility, reversibility and fast path to adoption. With Oracle Engineered Systems (Exadata, Exalogic & SPARC SuperCluster, more specifically, when talking about Cloud), we are delivering all those components hardware and software already engineered together at Oracle factory, with a single pane of glace for the management of ALL the components through Oracle Enterprise Manager, and with high-availability, scalability and ability to evolve by design. To give you a feeling of what does that bring in terms just of implementation project timeline, for example with Oracle SPARC SuperCluster, we have a consistent track of record to have the system plug into existing Datacenter and ready in a week. This includes Oracle Database, OS, virtualization, Database Storage (Exadata Storage Cells in this case), Application Storage, and all network configuration. This strategy enable CIOs to very quickly build Cloud Services, taking out not only the complexity of integrating everything together but also taking out the automation and evolution complexity and cost. I invite you to discuss all those aspect in regards of your particular context face2face on November 28th.

  • Fastest way to run a JSON server on my local machine

    - by Mohsen
    I am a front-end developer. For many experiemnets I do I need to have a server that talks JSON with my client side app. Normally that server is a simple server that response to my POSTs and GETs. For example I need to setup a server that saves, modifies and read data from a "library" database like this: POST /books create a book GET /book/:id gets a book and so on... What is the fastest and easiest technology stack for database and server in this case? I am open to use Ruby, Nodejs and anything that do the job fast and easy. Is there any framework (on any language) that do stuff like this for me?

  • Problem installing Oracle 10g Express edition

    - by abhi
    I have installed Oracle 10g Express edition in Ubuntu 10.10 and it doesn't show or ask to give my password during installation. When I click on "start database" it gave the warning "Operation failed, abhi is not a member of 'dba' group." and when clink on "Run SQL command line" it shows /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh: 114: [[: not found When I click on "GOTO Database home page", it opens Mozilla's "Ubuntu Google search page". Can anyone help me get my Oracle to work or tell me how to remove that because it is also not getting removed. I tried all the commands that are given as suggestions by Ubuntu. Please help me because I don't want to format my Ubuntu.

  • How to write functionally in a web framework

    - by Kevin Burke
    I love Rich Hickey, Clojure and Haskell and I get it when he talks about functions and the unreliability of side-effecting code. However I work in an environment where nearly all the functions I write have to read from the database, write to the database, make HTTP requests, decrement a user's balance, modify a frontend HTML component based on a click action, return different results based on the URI or the POST body. We also use PHP for the frontend, which is littered with functions like parse_str(), which modifies an object in place. All of these are side-effecting to one degree or another. Given these constraints and the side-effecting nature of the logic I'm coding, what can I do to make my code more reliable and function-able?

  • Where can I find accessible bug/issue databases with complete revision history

    - by namenlos
    I'm performing some research and analysis on bug/issue tracking databases and more specifically on how programmers and teams of programmers actually interact with them. What I'm looking for involves understanding how those databases change over time. So what I don't need for example: is a database of all the bugs of some open source project as the bugs exist today. What I do need is a complete set of revision history for every issue/bug in the database. This would enable me to pick a specific datetime and say here were the list of all the issues/bugs that existed at that moment in time. Anyway know of some publicly accessible issue/bug databases that expose this revision data? Ideally, the revision would look something like this (shown for a single bug, with two revisions) ISSUEID PRI SEV ASSIGNEDTO MODIFIEDON VALIDUNTIL 1 2 2 mel apr-1-2010:5pm apr-1-2010:6pm 1 2 3 steve apr-1-2010:6pm NULL

  • How to SET TIMING ON for parallel upgrades to 12c?

    - by Mike Dietrich
    Have you asked yourself how to get timings in an Oracle Database 12c upgrade for all statements? When you run the parallel upgrade via catctl.pl, the parallel upgrade Perl driving script in Oracle Database 12c, you may also want to get timings written in your logfile during execution. As catctl.pl does not offer an option yet the best way to achieve this is to edit the catupses.sql script in $ORACLE/rdbms/admin as this script will get called all time over and over again throughout all steps of theupgrade run. Just add these lines marked in RED to catupses.sql and start your upgrade: Rem =============================================Rem Call Common session settingsRem =============================================@@catpses.sql Rem =============================================Rem  Set Timing On during the UpgradeRem =============================================SET TIMING ON; Rem =============================================Rem Turn off PL/SQL event used by APPSRem =============================================ALTER SESSION SET EVENTS='10933 trace name context off'; -Mike PS: This may become the default in a future patch set

  • Questions about identifying the components in MVC

    - by luiscubal
    I'm currently developing an client-server application in node.js, Express, mustache and MySQL. However, I believe this question should be mostly language and framework agnostic. This is the first time I'm doing a real MVC application and I'm having trouble deciding exactly what means each component. (I've done web applications that could perhaps be called MVC before, but I wouldn't confidently refer to them as such) I have a server.js that ties the whole application together. It does initialization of all other components (including the database connection, and what I think are the "models" and the "views"), receiving HTTP requests and deciding which "views" to use. Does this mean that my server.js file is the controller? Or am I mixing code that doesn't belong there? What components should I break the server.js file into? Some examples of code that's in the server.js file: var connection = mysql.createConnection({ host : 'localhost', user : 'root', password : 'sqlrevenge', database : 'blog' }); //... app.get("/login", function (req, res) { //Function handles a GET request for login forms if (process.env.NODE_ENV == 'DEVELOPMENT') { mu.clearCache(); } session.session_from_request(connection, req, function (err, session) { if (err) { console.log('index.js session error', err); session = null; } login_view.html(res, user_model, post_model, session, mu); //I named my view functions "html" for the case I might want to add other output types (such as a JSON API), or should I opt for completely separate views then? }); }); I have another file that belongs named session.js. It receives a cookies object, reads the stored data to decide if it's a valid user session or not. It also includes a function named login that does change the value of cookies. First, I thought it would be part of the controller, since it kind of dealt with user input and supplied data to the models. Then, I thought that maybe it was a model since it dealt with the application data/database and the data it supplies is used by views. Now, I'm even wondering if it could be considered a View, since it outputs data (cookies are part of HTTP headers, which are output)

  • Top 25 security issues for developers of web sites

    - by BizTalk Visionary
    Sourced from: CWE This is a brief listing of the Top 25 items, using the general ranking. NOTE: 16 other weaknesses were considered for inclusion in the Top 25, but their general scores were not high enough. They are listed in the On the Cusp focus profile. Rank Score ID Name [1] 346 CWE-79 Failure to Preserve Web Page Structure ('Cross-site Scripting') [2] 330 CWE-89 Improper Sanitization of Special Elements used in an SQL Command ('SQL Injection') [3] 273 CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') [4] 261 CWE-352 Cross-Site Request Forgery (CSRF) [5] 219 CWE-285 Improper Access Control (Authorization) [6] 202 CWE-807 Reliance on Untrusted Inputs in a Security Decision [7] 197 CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') [8] 194 CWE-434 Unrestricted Upload of File with Dangerous Type [9] 188 CWE-78 Improper Sanitization of Special Elements used in an OS Command ('OS Command Injection') [10] 188 CWE-311 Missing Encryption of Sensitive Data [11] 176 CWE-798 Use of Hard-coded Credentials [12] 158 CWE-805 Buffer Access with Incorrect Length Value [13] 157 CWE-98 Improper Control of Filename for Include/Require Statement in PHP Program ('PHP File Inclusion') [14] 156 CWE-129 Improper Validation of Array Index [15] 155 CWE-754 Improper Check for Unusual or Exceptional Conditions [16] 154 CWE-209 Information Exposure Through an Error Message [17] 154 CWE-190 Integer Overflow or Wraparound [18] 153 CWE-131 Incorrect Calculation of Buffer Size [19] 147 CWE-306 Missing Authentication for Critical Function [20] 146 CWE-494 Download of Code Without Integrity Check [21] 145 CWE-732 Incorrect Permission Assignment for Critical Resource [22] 145 CWE-770 Allocation of Resources Without Limits or Throttling [23] 142 CWE-601 URL Redirection to Untrusted Site ('Open Redirect') [24] 141 CWE-327 Use of a Broken or Risky Cryptographic Algorithm [25] 138 CWE-362 Race Condition Cross-site scripting and SQL injection are the 1-2 punch of security weaknesses in 2010. Even when a software package doesn't primarily run on the web, there's a good chance that it has a web-based management interface or HTML-based output formats that allow cross-site scripting. For data-rich software applications, SQL injection is the means to steal the keys to the kingdom. The classic buffer overflow comes in third, while more complex buffer overflow variants are sprinkled in the rest of the Top 25.

  • Google's process for publishing/modifying pages [closed]

    - by Glenn Dayton
    I'm assuming that a group of people at Google have control of certain sections of google.com, but how does Google make sure that employees don't accidentally or intentionally sabotage the website? Does Google use Adobe Contribute or some similar product for sharing/publishing the website. Do employees use WebDAV, FTP, SFTP, or SSH to publish the site. Since Google has hundreds of thousands of servers it probably takes some time for its servers to update. Do they transmit the new copy of the website to all servers before publishing at once? This question does not apply to Google editing a database and having a page reflect the database's changes. It applies to employees editing the source code and/ or back end of the site.

  • Enabling EUS support in OUD 11gR2 using command line interface

    - by Sylvain Duloutre
    Enterprise User Security (EUS) allows Oracle Database to use users & roles stored in LDAP for authentication and authorization.Since the 11gR2 release, OUD natively supports EUS. EUS can be easily configured during OUD setup. ODSM (the graphical admin console) can also be used to enable EUS for a new suffix. However, enabling EUS for a new suffix using command line interface is currently not documented, so here is the procedure: Let's assume that EUS support was enabled during initial setup.Let's o=example be the new suffix I want to use to store Enterprise users. The following sequence of command must be applied for each new suffix: // Create a local database holding EUS context infodsconfig create-workflow-element --set base-dn:cn=OracleContext,o=example --set enabled:true --type db-local-backend --element-name exampleContext -n // Add a workflow element in the call path to generate on the fly attributes required by EUSdsconfig create-workflow-element --set enabled:true --type eus-context --element-name eusContext --set next-workflow-element:exampleContext -n // Add the context to a workflow for routingdsconfig create-workflow --set base-dn:cn=OracleContext,o=example --set enabled:true --set workflow-element:eusContext --workflow-name exampleContext_workflow -n //Add the new workflow to the appropriate network groupdsconfig set-network-group-prop --group-name network-group --add workflow:exampleContext_workflow -n // Create the local database for o=exampledsconfig create-workflow-element --set base-dn:o=example --set enabled:true --type db-local-backend --element-name example -n // Create a workflow element in the call path to the user data to generate on the fly attributes expected by EUS dsconfig create-workflow-element --set enabled:true --set eus-realm:o=example --set next-workflow-element:example --type eus --element-name eusWfe// Add the db to a workflow for routingdsconfig create-workflow --set base-dn:o=example --set enabled:true --set workflow-element:eusWfe --workflow-name example_workflow -n //Add the new workflow to the appropriate network groupdsconfig set-network-group-prop --group-name network-group --add workflow:example_workflow -n  // Add the appropriate acis for EUSdsconfig set-access-control-handler-prop \           --add global-aci:'(target="ldap:///o=example")(targetattr="authpassword")(version 3.0; acl "EUS reads authpassword"; allow (read,search,compare) userdn="ldap:///??sub?(&(objectclass=orclservice)(objectclass=orcldbserver))";)' dsconfig set-access-control-handler-prop \       --add global-aci:'(target="ldap:///o=example")(targetattr="orclaccountstatusevent")(version 3.0; acl "EUS writes orclaccountstatusenabled"; allow (write) userdn="ldap:///??sub?(&(objectclass=orclservice)(objectclass=orcldbserver))";)' Last but not least you must adapt the content of the ${OUD}/config/EUS/eusData.ldif  file with your suffix value then inport it into OUD.

  • At what size of data does it become beneficial to move from SQL to NoSQL?

    - by wobbily_col
    As a relational database programmer (most of the time), I read articles about how relational databases don't scale, and NoSQL solutions such as MongoDB do. As most of the databases I have developed so far have been small to mid scale, I have never had a problem that hasn't been solved by some indexing, query optimization or schema redesign. What sort of size would I expect to see MySQL struggling with. How many rows? (I know this is going to depend on the application, and type of data stored. the one that got me thing was basically a genetics database, so would have one main table, with 3 or 4 lookup tables. The main table will contain amongst other things, a chromosome reference, and a position coordinate. It will likely get queried for a number of entries between two potions on a chromosome, to see what is stored there).

  • Vantec NexStar NAS Encloser - Writing large files

    - by peter
    Hi, I have one of these 'Vantec NexStar LX - NST-475LX-BK' drive enclosures. It is a NAS drive. When I write a file to the device using eSata, or a SMB share I cannot write files over 2GB. I think this is because the drive is formatted with FAT32. But when I access the device using FTP it doesn't matter. I can write files of any size. E.g. I wrote one on there last night which was 30GB. Does this make any sense? Why? I guess the most important thing for me is data integrity.

  • C# WebForms and Ninject

    - by ipohfly
    I'm re-working on the design of an existing application which is build using WebForms. Currently the plan is to work it into a MVP pattern application while using Ninject as the IoC container. The reason for Ninject to be there is that the boss had wanted a certain flexibility within the system so that we can build in different flavor of business logic in the model and let the programmer to choose which to use based on the client request, either via XML configuration or database setting. I know that Ninject have no need for XML configuration, however I'm confused on how it can help to dynamically inject the dependency into the system? Imagine I have a interface IMember and I need to bind this interface to the class decided by a xml or database configuration at the launch of the application, how can I achieve that?

  • Should I just always Convert.ToInt32 my integers to account for potential nullable integers?

    - by Rowan Freeman
    If my MSSQL database contains a data type that is NULL (i.e. null is allowed) then ORMs, such as EntityFramework in my case, create .NET objects that are nullable. This is great, and the way I use nullables is like this: C# int? someInt = 5; int newInt = someInt.Value; // woot VB.NET Dim someInt As Integer? Dim newInt As Integer = someInt.Value ' hooray However, recently I had to make a change to the database to make an Id field no longer NULL (nullable). This means that .Value is now broken. This is a nuisance if the Id property is used a lot. One solution that I thought of is to just use Convert.ToInt32 on Id fields so it doesn't matter if an int is nullable or not. C# int newInt = Convert.ToInt32(someInt); // always compiles VB.NET Dim newInt As Integer = Convert.ToInt32(someInt) ' always compiles Is this a bad approach and are there any alternatives?
