  • Double Free inside of a destructor upon adding to a vector

    - by Shawn B
    Hey, I am working on a drum machine, and am having problems with vectors. Each Sequence has a list of samples, and the samples are ordered in a vector. However, when a sample is push_back on the vector, the sample's destructor is called, and results in a double free error. Here is the Sample creation code: class XSample { public: Uint8 Repeat; Uint8 PlayCount; Uint16 Beats; Uint16 *Beat; Uint16 BeatsPerMinute; XSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat); ~XSample(); void GenerateSample(); void PlaySample(); }; XSample::XSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat) { Beats = NewBeats; BeatsPerMinute = NewBPM; Repeat = NewRepeat-1; PlayCount = 0; printf("XSample Construction\n"); Beat = new Uint16[Beats]; } XSample::~XSample() { printf("XSample Destruction\n"); delete [] Beat; } And the 'Dynamo' code that creates each sample in the vector: class XDynamo { public: std::vector<XSample> Samples; void CreateSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat); }; void XDynamo::CreateSample(Uint16 NewBeats,Uint16 NewBPM,Uint8 NewRepeat) { Samples.push_back(XSample(NewBeats,NewBPM,NewRepeat)); } Here is main(): int main() { XDynamo Dynamo; Dynamo.CreateSample(4,120,2); Dynamo.CreateSample(8,240,1); return 0; } And this is what happens when the program is run: Starting program: /home/shawn/dynamo2/dynamo [Thread debugging using libthread_db enabled] XSample Construction XSample Destruction XSample Construction XSample Destruction *** glibc detected *** /home/shawn/dynamo2/dynamo: double free or corruption (fasttop): 0x0804d008 *** However, when the delete [] is removed from the destructor, the program runs perfectly. What is causing this? Any help is greatly appreciated.

  • Quick guide to Oracle IRM 11g: Server configuration

    - by Simon Thorpe
    Quick guide to Oracle IRM 11g index Welcome to the second article in this quick quide to Oracle IRM 11g. Hopefully you've just finished the first article which takes you through deploying the software onto a Linux server. This article walks you through the configuration of this new service and contains a subset of information from the official documentation and is focused on installing the server on Oracle Enterprise Linux. If you are planning to deploy on a non-Linux platform, you will need to reference the documentation for platform specific information. Contents Introduction Create IRM WebLogic Domain Starting the Admin Server and initial configuration Introduction In the previous article the database was prepared, the WebLogic Application Server installed and the files required for an IRM server installed. But we don't actually have a configured system yet. We need to now create a WebLogic Domain in which the IRM server will run, then configure some of the settings and crypography so that we can create a context and be ready to seal some content and test it all works. This article doesn't cover the configuration of SSL communication from client to server. This is quite a big topic and a separate article has been dedicated for this area. In these articles I also use the hostname, irm.company.internal to reference the IRM server and later on use the hostname irm.company.com in reference to the public facing service. Create IRM WebLogic Domain First step is creating the WebLogic domain, in a console switch to the newly created IRM installation folder as shown below and we will run the domain configuration wizard. [oracle@irm /]$ cd /oracle/middleware/Oracle_IRM/common/bin [oracle@irm bin]$ ./config.sh First thing the wizard will ask is if you wish to create a new or extend an existing domain. This guide is creating a standalone system so you should select to create a new domain. Next step is to choose what technologies from the Oracle ECM Suite you wish this domain to host. You are only interested in selecting the option "Oracle Information Rights Management". When you select this check box you will notice that it also selects "Oracle Enterprise Manager" and "Oracle JRF" as these are dependencies of the IRM server. You then need to specify where you wish to place the domain files. I usually just change the domain name from base_domain or irm_domain and leave the others with their defaults. Now the domain will have a single user initially and by default this user is called "weblogic". I usually change this account name to "sysadmin" or "administrator", but in this guide lets just accept the default. With respects to the next dialog, again for eval or dev reasons, leave the server startup mode as development. The JDK should also be automatically detected. We now need to provide details of the database. This guide is using the Oracle 11gR2 database and the settings I used can be seen in the image to the right. There is a lot of configuration that can now be done for the admin server, any managed servers and where the deployments reside. In this guide I am leaving all of these to their defaults so do not check any of the boxes. However I will on this blog be detailing later how you can go back and setup things such as automated startup of an IRM server which require changes to these default settings. But for now, lets leave it all alone and just click next. Now we are ready to install. Note that from this dialog you can scroll the left window and see there are going to be two servers created from the defaults. The AdminServer which is where you modify settings for the WebLogic Server and also hosts the Oracle Enterprise Manager for IRM which allows to monitor the IRM service performance and also make service related settings (which we shortly do below) and the IRM_server1 which hosts the actual IRM services themselves. So go right ahead and hit create, the process is pretty quick and usually under 10 minutes. When the domain creation ends, it will give you the URL to the admin server. It's worth noting this down and the URL is usually; http://irm.company.internal:7001 Starting the Admin Server and initial configuration First thing to do is to start the WebLogic Admin server and review the initial IRM server settings. In this guide we are going to run the Admin server and IRM server in console windows, in another article I will discuss running these as background services. So for now, start a console and run the Admin server by doing the following. cd /oracle/middleware/user_projects/domains/irm_domain/ ./startWebLogic.sh Wait for the server to start, you are looking for the following line to be reported in the console window. <BEA-00360><Server started in RUNNING mode> First step is configuring the IRM service via Enterprise Manager. Now that the Admin server is running you can point a browser at http://irm.company.internal:7001/em. Login with the username and password you supplied when you created the domain. In Enterprise Manager the IRM service administrator is able to make server wide configuration. However finding where to access the pages with these settings can be a bit of a challenge. After logging in on the left you'll see a tree containing elements of the Enterprise Manager farm Farm_irm_domain. Open up Content Management, then Information Rights Management and finally select the IRM node. On the right then select the IRM menu item, navigate to the Administration section and now we have four options, for now, we are just going to look at General Settings. The image on the right proves that a picture is worth a thousand words (or 113 in this case). The General Settings page allows you to set the cryptographic algorithms used for protecting sealed content. Unless you have a burning need to increase the key lengths or you need to comply to a regulation or government mandate, AES192 is a good start. You can change this later on without worry. The most important setting here we need to make is the Server URL. In this blog article I go over why this URL is so important, basically every single piece of content you protect with Oracle IRM is going to have this URL embedded in it, so if it's wrong or unresolvable, then nobody can open the secured documents. Note that in our environment we have yet to do any SSL configuration of the service. If you intend to build a server without SSL, then use http as the protocol instead of https. But I would recommend using SSL and setting this up is described in the next article. I would also probably up the device count from 1 to 3. This means that any user can retrieve rights to access content onto 3 computers at any one time. The default of 1 doesn't really make sense in development, evaluation nor even production environments and my experience is that 3 is a better number. Next step is to create the keystore for the IRM server. When a classification (called a context) is created, Oracle IRM generates a unique set of symmetric keys which are used to secure the content itself. These keys are then encrypted with a set of "wrapper" asymmetric cryptography keys which are stored externally to the server either in a Java Key Store or a HSM. These keys need to be generated and the following shows my commands and the resulting output. I have greyed out the responses from the commands so you can see the input a little easier. [oracle@irmsrv ~]$ cd /oracle/middleware/wlserver_10.3/server/bin/ [oracle@irmsrv bin]$ ./setWLSEnv.sh CLASSPATH=/oracle/middleware/patch_wls1033/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/oracle/middleware/patch_ocp353/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/usr/java/jdk1.6.0_18/lib/tools.jar:/oracle/middleware/wlserver_10.3/server/lib/weblogic_sp.jar:/oracle/middleware/wlserver_10.3/server/lib/weblogic.jar:/oracle/middleware/modules/features/weblogic.server.modules_10.3.3.0.jar:/oracle/middleware/wlserver_10.3/server/lib/webservices.jar:/oracle/middleware/modules/org.apache.ant_1.7.1/lib/ant-all.jar:/oracle/middleware/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar: PATH=/oracle/middleware/wlserver_10.3/server/bin:/oracle/middleware/modules/org.apache.ant_1.7.1/bin:/usr/java/jdk1.6.0_18/jre/bin:/usr/java/jdk1.6.0_18/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/oracle/bin Your environment has been set. [oracle@irmsrv bin]$ cd /oracle/middleware/user_projects/domains/irm_domain/config/fmwconfig/ [oracle@irmsrv fmwconfig]$ keytool -genkeypair -alias oracle.irm.wrap -keyalg RSA -keysize 2048 -keystore irm.jks Enter keystore password: Re-enter new password: What is your first and last name? [Unknown]: Simon Thorpe What is the name of your organizational unit? [Unknown]: Oracle What is the name of your organization? [Unknown]: Oracle What is the name of your City or Locality? [Unknown]: San Francisco What is the name of your State or Province? [Unknown]: CA What is the two-letter country code for this unit? [Unknown]: US Is CN=Simon Thorpe, OU=Oracle, O=Oracle, L=San Francisco, ST=CA, C=US correct? [no]: yes Enter key password for (RETURN if same as keystore password): At this point we now have an irm.jks in the directory /oracle/middleware/user_projects/domains/irm_domain/config/fmwconfig. The reason we store it here is this folder would be backed up as part of a domain backup. As with any cryptographic technology, DO NOT LOSE THESE KEYS OR THIS KEY STORE. Once you've sealed content against a context, the keys will be wrapped with these keys, lose these keys, and you can't get access to any secured content, pretty important. Now we've got the keys created, we need to go back to the IRM Enterprise Manager and set the location of the key store. Going back to the General Settings page in Enterprise Manager scroll down to Keystore Settings. Leave the type as JKS but change the location to; /oracle/Middleware/user_projects/domains/irm_domain/config/fmwconfig/irm.jks and hit Apply. The final step with regards to the key store is we need to tell the server what the password is for the Java Key Store so that it can be opened and the keys accessed. Once more fire up a console window and run these commands (again i've greyed out the clutter to see the commands easier). You will see dummy passed into the commands, this is because the command asks for a username, but in this instance we don't use one, hence the value dummy is passed and it isn't used. [oracle@irmsrv fmwconfig]$ cd /oracle/middleware/Oracle_IRM/common/bin/ [oracle@irmsrv bin]$ ./wlst.sh ... lots of settings fly by... Welcome to WebLogic Server Administration Scripting Shell Type help() for help on available commands wls:/offline>connect('weblogic','password','t3://irmsrv.us.oracle.com:7001') Connecting to t3://irmsrv.us.oracle.com:7001 with userid weblogic ...

The domain creation created a managed server called IRM_server1 and we need to start this, use the following commands in a new console window. cd /oracle/middleware/user_projects/domains/irm_domain/bin/ ./startManagedWebLogic.sh IRM_server1 This will start up the server in the console, unlike the Admin server, you need to provide the username and password for the service to start. Enter in your weblogic username and password when prompted. You can change this behavior by putting the password into a boot.properties file, read more about this in the WebLogic Server documentation. Once running, wait until you see the line; <Notice><WebLogicServer><BEA-000360><Server started in RUNNING mode> At this point we can now login to the Oracle IRM Management Website at the URL. http://irm.company.internal:1600/irm_rights/ The server is just configured for HTTP at the moment, no SSL involved. Just want to ensure we can get a working system up and running. You should now see a login like the image on the right and you can now login using your weblogic username and password. The next article in this guide goes over adding SSL and now testing your server by actually adding a few users, sealing some content and opening this content as a user.

  • Hardware for 4 Monitors

    - by Simon
    Looking to build several systems to output to 4 monitors over DVI. I notice most of the recent Nvidia and ATI/AMD cards have dual-DVI ports. Can I simply install two of these cards to get four monitors - or are only some cards capable of running side-by-side with another? How can I tell before purchasing? Simon.

  • Inside Red Gate - Divisions

    - by Simon Cooper
    When I joined Red Gate back in 2007, there were around 80 people in the company. Now, around 3 years later, it's grown to more than 200. It's a constant battle against Dunbar's number; the maximum number of people you can keep track of in a social group, to try and maintain that 'small company' feel that attracted myself and so many others to apply in the first place. There are several strategies the company's developed over the years to try and mitigate the effects of Dunbar's number. One of the main ones has been divisionalisation. Divisions The first division, .NET, appeared around the same time that I started in 2007. This combined the development, sales, marketing and management of the .NET tools (then, ANTS Profiler v3) into a separate section of the office. The idea was to increase the cohesion and communication between the different people involved in the entire lifecycle of the tools; from initial product development, through to marketing, then to customer support, who would feed back to the development team. This was such a success that the other development teams were re-worked around this model in 2009. Nowadays there are 4 divisions - SQL Tools, DBA, .NET, and New Business. Along the way there have been various tweaks to the details - the sales teams have been merged into the divisions, marketing and product support have been (mostly) centralised - but the same basic model remains. So, how has this helped? As Red Gate has continued to grow over the years, divisionalisation has turned Red Gate from a monolithic software company into what one person described as a 'federation of small businesses'. Each division is free to structure itself as it sees fit, it's free to decide what to concentrate development work on, organise its own newsletters and webinars, decide its own release schedule. Each division is its own small business. In terms of numbers, the size of each division varies from 20 people (.NET) to 52 (SQL Tools); well below Dunbar's number. From a developer's perspective, this means organisational structure is very flat & wide - there's only 2 layers between myself and the CEOs (not that it matters much; everyone can go and have a chat to Neil or Simon, or anyone else inbetween, whenever they want. Provided you can catch them at their desk!). As Red Gate grows, and expands into new areas, new divisions will be created as needed, old ones merged or disbanded, but the division structure will help to maintain that small-company feel that keeps Red Gate working as it does.

  • Inheritance using prototype / "new"

    - by mikkol
    Hi I'm new in Javascript OO and want to know more about about inheritance. Hope you can provide some advice! I see this great post: How to "properly" create a custom object in JavaScript? which talks about how a class is inherited as I see in other websites, ex.: function man(x) { this.x = x; this.y = 2; } man.prototype.name = "man"; man.prototype.two = function() { this.y = "two"; } function shawn() { man.apply(this, arguments); }; shawn.prototype = new man; The above post claims that in order not to call "man"'s constructor while inheriting, one can use a helper like this instead: function subclassOf(base) { _subclassOf.prototype= base.prototype; return new _subclassOf(); } function _subclassOf() {}; shawn.prototype = subclassOf(man); While I understand its intention, I don't see why we can't call shawn.prototype = man.prototype; I see it works exactly the same. Or is there something I'm missing? Thanks in advance!

  • mount network drive

    - by CaptnLenz
    since i updated my ubuntu to natty narwhal(from 10.04), my mount script doesn't work anymore. The scripts mounts a folder from a NAS (WD mybookworld) in the local network to a folder in my home folder. script looked like that: #!/bin/bash sudo mount //192.168.2.222/Public/Shared\ Music/ /home/simon/Musik/ error: mount: wrong fs type, bad option, bad superblock on //192.168.2.222/Public/Shared Music/, missing codepage or helper program, or other error (for several filesystems (e.g. nfs, cifs) you might need a /sbin/mount.<type> helper program) Manchmal liefert das Syslog wertvolle Informationen – versuchen Sie dmesg | tail oder so now, because the script doesn't work anymore i decided to add the mount-process to my fstab, because the network drive should be mounted on every startup. My fstab entry looks like this: //192.168.2.222/Public/Shared\ Music/ /home/simon/Musik cifs credentials=/home/simon/.smbcredentials 0 0 But it doesn't work, too. I get a message during the startup process, that Musik couldn't be mounted. Are there any log files i can check for errors? The system is a fresh installed 11.04. Greetings

  • Inside Red Gate - The Office

    - by Simon Cooper
    The vast majority of Red Gate is on the first and second floors (the second and third floors in US parlance) of an office building in Cambridge Business Park (here we are!). As you can see, the building is split into three sections; the two wings, and the section between them. As well as being organisationally separate, the four divisions are also split up in the office; each division has it's own floor and wing, so everyone in the division is working together in the same area (.NET and DBA on the left, SQL Tools and New Business on the right). The non-divisional parts of the business share wings with the smaller divisions, again keeping each group together. The canteen One of the downsides of divisionalisation is that communication between people in different decisions is greatly reduced. This is where the canteen (aka the SQL Servery) comes in. Occupying most of the central section on the first floor, the canteen provides free cooked lunch every day, and is where everyone in the company gathers for lunch. The idea is to encourage communication between the divisions; having lunch with people in a different division you wouldn't otherwise talk to helps people keep track of what's going on elsewhere in the company. (I'm still amazed at how the canteen staff provide a wide range of superbly cooked food for over 200 people out of a kitchen in which, if you were to swing a cat, it would get severe head injuries.). There's also table tennis and table football tables that anyone can use, provided you can grab them when they're free! Office layout Cubicles are practically unheard of in the UK, and no one, including the CEOs, has separate offices. The entire office is open-plan, as you can see in this youtube video from when we first moved in (although all the empty desks are now full!). Neil & Simon, instead of having dedicated offices, move between the different divisions every few months to keep up to date with what's going on around the company; sitting with a division gives you a much better overall impression of how the division's doing than written status reports from the division heads. There's also the usual plethora of meeting rooms scattered around the place; when we first moved in in 2009 we had a competition to name them all. We've got Afoxalypse A & B, Seagulls A & B, Traffic Jam, Thinking Hats, Camelids A & B, Horses, etc. All the meeting rooms have pictures on the walls corresponding to their theme, which adds a nice bit of individuality to otherwise fairly drab meeting rooms. Generally, any meeting room can be booked by anyone at any time, although some groups have priority in certain rooms (Camelids B is used a lot for UX testing, the Interview Room is used for, well, interviews). And, as you can see from the video, each area has various pictures, post-its, notes, signs, on the walls to try and stop it being a dull office space. Yes, it's still an office, but it's designed to be as interesting and as individual as possible.

  • What configuration changes can I make to speed up extremely slow Windows VM's in ESXi 4.0.

    - by Shawn Anderson
    I've recently moved from VMWare Server to ESXi 4.0. Running on Dell T310. My VM's have been restored but they are running dog slow compared to VMWare Server. I loaded ESXi 4.0 using only default values. Where are some areas where I can tweak the performance? Even logging onto the VM's can be extremely sluggish. Trying to install software on any of them is a new experience in pain. Dell PowerEdge T310 Xeon X3460 2.80 GHz 32 GB RAM 1 HD (2 TB) I have 16 VM's on this server, but only six or so will be running during my testing. I keep an eye on the Resource Allocation and Performance tabs for the host and I never see CPU or RAM getting anywhere close to pegged. Events tab does show some notices for video RAM issues and some hints on Windows activation issues, but nothing that would point to the sort of sluggishness that I'm experiencing. 1 Windows Server 2008 R2 (64-bit) - 4 GB RAM 1 Windows 7 (32-bit) - 2 GB RAM 1 Vista (32-bit) - 1 GB RAM 3 XP (32-bit) - 1 GB RAM Over to you!

  • Lock down SFTP access on OpenSolaris

    - by Simon
    Hi all, I have an OpenSolaris 2009.06 server and I'd like to enable a user to remotely change files in a specific directory, ideally via SFTP or FTP-via-SSH. This user does not yet have an account on the machine and I'd like to create it so it's as restricted as possible. Is there a canonical way of doing this? I know about OpenSolaris' role-based access control and authorizations model, but I figure it's a lot of work (i.e., a lot I can mess up) to really lock down a full-blown user account (prevent fork bombs, make sure there's really no other file in the file system which can be written to...). Any hint is greatly appreciated. Thanks, Simon

  • Custom dedicated email server combined with Amazon AWS?

    - by Simon
    Hi there. We are considering moving our servers to Amazone EC2 cloud. The only thing that stops right now is their problems with ip ranges banned from spam mail lists like SORBS. We are considering leaving one dedicated server in our current hosting, the one which we use to send mail (and other several features we will move to EC2), in order to be able to send the mails from this smtp server instead from Amazon. So, the idea is to have our sites hosted in EC2, and when they need to send mail, redirect they to our "local" smtp server. Do you think it´s viable? Can you think on a better solution? Thanks in advance, Simon.

  • How to alter mail-from postfix?

    - by Simon
    Hi all, do anyone know how to alter the mail-from of a postfix mail server? Example, I have a postfix mail server which sends mail for the domain example.org. When a linux user, whose account is user.example.org (mapped in postfix/virtual to [email protected]), try to send an email, its mail from is [email protected]. HELO hostname: server.hostname.org Source IP: one ip here mail-from: [email protected] Problems: user.example.org instead of just user. server.hostname.org instead of just example.org. Desired mail-from: [email protected]. This is causing me problems with SPF records for example (example.org differs from server.hostname.org)... any idea of what can be the problem? Thanks in advance, Simon.

  • Error installing Network driver

    - by Simon Carpentier
    I'm tring to install NetLimiter 3 (3.0.0.10, x64) on my Windows 7 x64 machine. At the driver installation step, I'm getting an error: Error 0x8004a029: Couldn't install the network component. (InstallNdisIMDriver) UPDATE 2010-09-20: I received a response to my support request: Hi Simon, It seems that problem is rather on your system than in NL3. Too many networking applications (VPN, Virtual computers) are installed on your machine and they are preventing NL3 from proper installation. In order to install NetLimiter 3, try to disable/temporarily remove these apps. Several users had the same problem and shuffling with adapter and networking software helped them. Please, let us know which action helps you (if any). Sincerely, Jan Bilek Any thoughts on this?

  • Block a machine from accessing the internet

    - by Simon Rigby
    After some confirmation that I have thinking right in this scenario. We have a number of wired and wireless machines which presently have direct internet access. I also have a Linux (Ubuntu) server which is used as a file server for the network. Essentially I would like to be able to turn internet access on and off for machines. My plan is to block these machines by MAC address at the router. I would then set up a proxy server on the Linux box (ie Squid) so that the machines I wish to restrict can access the internet via the proxy. As I can adjust access via ACLs in squid, I would be able to switch on or off a machines access to the internet without having to further adjust the router's MAC rules. And of course I could go further and create a few scripts to assist with this admin task. Does this seem sound and have I over looked anything? Any help greatly appreciated. Simon.
