• Writing a "Hello World" Device Driver for kernel 2.6 using Eclipse

  - by Isaac

  Goal I am trying to write a simple device driver on Ubuntu. I want to do this using Eclipse (or a better IDE that is suitable for driver programming). Here is the code: #include <linux/module.h> static int __init hello_world( void ) { printk( "hello world!\n" ); return 0; } static void __exit goodbye_world( void ) { printk( "goodbye world!\n" ); } module_init( hello_world ); module_exit( goodbye_world ); My effort After some research, I decided to use Eclipse CTD for developing the driver (while I am still not sure if it supports multi-threading debugging tools). So I: Installed Ubuntu 11.04 desktop x86 on a VMWare virtual machine, Installed eclipse-cdt and linux-headers-2.6.38-8 using Synaptic Package Manager, Created a C Project named TestDriver1 and copy-pasted above code to it, Changed the default build command, make, to the following customized build command: make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 The problem I get an error when I try to build this project using eclipse. Here is the log for the build: **** Build of configuration Debug for project TestDriver1 **** make -C /lib/modules/2.6.38-8-generic/build M=/home/isaac/workspace/TestDriver1 all make: Entering directory '/usr/src/linux-headers-2.6.38-8-generic' make: *** No rule to make target vmlinux', needed byall'. Stop. make: Leaving directory '/usr/src/linux-headers-2.6.38-8-generic' Interestingly, I get no error when I use shell instead of eclipse to build this project. To use shell, I just create a Makefile containing obj-m += TestDriver1.o and use the above make command to build. So, something must be wrong with the eclipse Makefile. Maybe it is looking for the vmlinux architecture (?) or something while current architecture is x86. Maybe it's because of VMWare? As I understood, eclipse creates the makefiles automatically and modifying it manually would cause errors in the future OR make managing makefile difficult. So, how can I compile this project on eclipse?

• Dubious permissions on plist Problems installing Jenkins

  - by Code Droid

  I am trying to install jenkins on 10.6.8 In order to do this I needed to modify the jenkins plist which was owned by root. I gave myself (the admin) permissions to modify this file and added the admin as the user in the plist for jenkins. Now the problem is that launchctrl sees my permission change as a security issue and will not launch something about dubious permissions on plist. I changed owner to root, and removed admin permission to write but launchctrl still views the permissions as dubious? Time for a reinstall? How should I have set the plist in the first place? and what should I do now?

• How can I tell what user account is being used by a service to access a network share on a Windows 2008 server?

  - by Mike B

  I've got a third-party app/service running on a Windows 2003 SP2 server that is trying to fetch something from a network share on Windows 2008 box. Both boxes are members of an AD domain. For some reason, the app is complaining about having insufficient permissions to read/write to the store. The app itself doesn't have any special options for acting on the authority of another user account. It just asks for a UNC path. The service is running with a "log on as" setting of Local System account. I'd like to confirm what account it's using when trying to communicate with the network share. Conversely, I'd also like more details on if/why it's being rejected by the Windows 2008 network share. Are there server-side logs on 2008 that could tell me exactly why a connection attempt to a share was rejected?

• Installing Windows Mobile SDK without Visual Studio

  - by Tester101

  Is it possible to install the Windows Mobile SDK without having Visual Studio? I am using SharpDevelop to write a Windows Mobile application, but I need to use an assembly in the Windows Mobile 6.0 SDK. When I try to install the SDK I get a message that says Visual Studio is a prerequisite, and I am un able to install it. Is there a way to trick it in to thinking Visual Studio is installed; maybe a registry entry that can be added or something, or am I just hosed? Is there a reason I need to pay for Microsoft's IDE, or is this just a way for Microsoft to make some extra money? Thanks,

• Demantra USA Based Companies and SOX Compliance

  - by user702295

  A USA based company is assessing Demantra Trade Promotion Management (TPM) capability.  It appears that SOX is necessary in their case due to the nature of what TPM does and the necessity for auditability.  Do we have any detail on SOX compliance for Demantra? Answser ------- SOX compliance with regards to IT: 1.  Requires auditing of data changes done by who, what, when     a. Audit trail profiles can be set up for key financial series and view them in audit trail reports     b. One functionality we do not have which typically is asked for is user login history. We have only        active sessions, history is not available. 2.  Segregation of duties     a. With respect to TPM, you could have deduction and financial analyst for settlement be different        from promotion creator, promotion approver or sales team.     b. Budget Approver for funds can be different from funds consumer.     c. Promotion creator can be different than promotion approver     d. For a US customer you may have to write some custom scripts to capture promotion status change        and produce an external report as part of compliance. One additional requirement is transparency of forward commitments entered into with retailers / distributors for trade spending, promotions.  Outside of Demantra - Consumer Goods Trade Funds Analytics.

• Efficiently checking input and firing events

  - by Jim

  I'm writing an InputHandler class in XNA, and there are several different keys considered valid input (all of type Microsoft.XNA.Framework.Input.Keys). For each key, I have three events: internal event InputEvent XYZPressed; internal event InputEvent XYZHeld; internal event InputEvent XYZReleased; where XYZ is the name of the Keys object representing that key. To fire these events, I have the following for each key: if (Keyboard.GetState().IsKeyDown(XYZ)) { if (PreviousKeyState.IsKeyDown(XYZ)) { if (XYZHeld != null) XYZHeld(); } else { if (XYZPressed != null) XYZPressed(); } } else if (PreviousKeyState.IsKeyDown(XYZ)) { if (XYZReleased != null) XYZReleased(); } However, this is a lot of repeated code (the above needs to be repeated for each input key). Aside from being a hassle to write, if any keys are added to/removed from the keys (if functionality is added/removed), a new section needs to be added (or an existing one removed). Is there a cleaner way to do this? Perhaps something along the lines of foreach key check which state it's in fire this key's event for that state where the code does the foreach (automatically checking exactly those keys that "exist") rather than the coder?

• Which Single Source Publishing tools and strategies are available?

  - by Another Registered User

  I'm about to write a 1000-Pages Documentation about a huge programming framework. The goal is to bring this documentation online into an web platform, so that online users can search through it and read it online. At the same time, the text has to be made public in PDF format for download. And at the same time, the whole thing needs to go into a printed book as well (print on demand, they want a giant PDF file with the whole book). The PDF files: The whole content is divided into several chapters. Every chapter will be available as a standalone PDF eBook. And finally, all chapters will be available in one huge printed book. Is LaTeX capable for something like that? Can it be used for Single Source Publishing? Or would I have to take a look at other technologies like DocBook, etc.?

• When to increase AWS RDS MySQL Server instance to larger CPU/RAM?

  - by rksprst

  I'm wondering at what stage do I need to increase the image for the RDS MySQL server to a larger CPU/RAM instance. The CPU utilization graph is near 0. The Avg Free Memory is around 150MB. The Avg Swap Usage is 420MB. Read Latency is 0-20ms/op it spikes up randomly. Avg write latency is on average 5ms/op but spikes up to 10-20ms/op. Are there some common rules here that I should follow? Thanks!

• High server load - [jbd2/md1-8] using 99.99% IO

  - by Alex

  I've been having spike in load over the last week. This usually occurs once or twice a day. I've managed to identify from iotop that [jbd2/md1-8] is using 99.99 % IO. During the high load times there is no high traffic to the server. Server specs are: AMD Opteron 8 core 16 GB RAM 2x2.000 GB 7.200 RPM HDD Software Raid 1 Cloudlinux + Cpanel Mysql is properly tuned Apart from the spikes, the load usually is around 0.80 at most. I've searched around but can't find what [jbd2/md1-8] does exactly. Has anyone had this problem or does anyone know a possible solution? Thank you.

• "Integratable" but not "integrated" GPL

  - by mgibsonbr

  There has been much debate over whether or not merely linking to a piece of code makes it a derivative work. I know FSF says "yes", so according to them I can't dynamically link a non-GPL compatible program to a GPL library and distribute the whole. But I could do that for private use, as long as no code is released to the public. That made me wonder: what if I don't redistribute the GPL code at all? If my program can work alone (reinforcing my claim that it's not a derivative work), but can do more if the GPL library is also installed to the system, couldn't I just release my application under my own licensing terms - without including any GPL code - and post instructions for anyone interested to separately download the GPL code and do the integration "for their private use"? I know it's against the "spirit" of the GPL, so I'm not suggesting it's a good idea to do that. However, this question is bugging me for some time, specially because of the implications of each answer: If I can not do that: can I write another library with a similar API? (before answering "of course you can", remember that having the same API would allow both libraries to be swapped at will by my customers - so I don't need to work too hard on my library or even make it "working". How to determine if a similar program is just similar or is a circumvention attempt?) If I can do that: can I also be paid to perform the service of installing the GPL library for a customer? (I sell them my program, install it in their machines, download and install the GPL library too) can I put the two programs in the same website? In two different CDs? (I know I said the idea was not to redistribute the GPL code, I'm just thinking in excuses people could use to claim they're not redistributing even though they are)

• I am looking for a script where users can create groups cms/social interaction site

  - by Paul

  I am trying to find a Content Mangement/social interaction script that requires a person to be a part of a group. Specifically: My daughter is a cheerleader and there are a number of cheer groups she is involved in and also has friends in many others. A lot of them could use some kind of website where they can share information between their team members and coach. The coach being the controller of the group and who can join etc. "Group Leader"? One can only join the group if invited or given a password or some such security. There would be multipel groups or in this case multiple cheer squads who were registered as groups and the cheerleaders a part of their group. The coach or group leader would have control of the group calender and they may have their own calendars and be messaging between them and/or other social interactions. IN a perfect world they could modify their own pages individualy. Communication could go globally or only to the group and a "friends or buddy" system. I think you get the idea. I really like OCportal and what it does and can do but it does not have the group funcitionality I am looking for. Perhaps I am just going to need to see about getting aprogrammer to write an add on for me if ther is nothing like this out there. But if you know of any I would appreciate being pointed in that direction.

• Unit testing internal methods in a strongly named assembly/project

  - by Rohit Gupta

  If you need create Unit tests for internal methods within a assembly in Visual Studio 2005 or greater, then we need to add an entry in the AssemblyInfo.cs file of the assembly for which you are creating the units tests for. For e.g. if you need to create tests for a assembly named FincadFunctions.dll & this assembly contains internal/friend methods within which need to write unit tests for then we add a entry in the FincadFunctions.dll’s AssemblyInfo.cs file like so : 1: [assembly: System.Runtime.CompilerServices.InternalsVisibleTo("FincadFunctionsTests")] where FincadFunctionsTests is the name of the Unit Test project which contains the Unit Tests. However if the FincadFunctions.dll is a strongly named assembly then you will the following error when compiling the FincadFunctions.dll assembly :      Friend assembly reference “FincadFunctionsTests” is invalid. Strong-name assemblies must specify a public key in their InternalsVisibleTo declarations. Thus to add a public key token to InternalsVisibleTo Declarations do the following: You need the .snk file that was used to strong-name the FincadFunctions.dll assembly. You can extract the public key from this .snk with the sn.exe tool from the .NET SDK. First we extract just the public key from the key pair (.snk) file into another .snk file. sn -p test.snk test.pub Then we ask for the value of that public key (note we need the long hex key not the short public key token): sn -tp test.pub We end up getting a super LONG string of hex, but that's just what we want, the public key value of this key pair. We add it to the strongly named project "FincadFunctions.dll" that we want to expose our internals from. Before what looked like: 1: [assembly: System.Runtime.CompilerServices.InternalsVisibleTo("FincadFunctionsTests")] Now looks like. 1: [assembly: System.Runtime.CompilerServices.InternalsVisibleTo("FincadFunctionsTests, 2: PublicKey=002400000480000094000000060200000024000052534131000400000100010011fdf2e48bb")] And we're done. hope this helps

• XML Schema For MBSA Reports

  - by Steve Hawkins

  I'm in the process of creating a script to run the command line version of Microsoft Baseline Security Analyzer (mbsacli.exe) against all of our servers. Since the MBSA reports are provided as XML documents, I should be able to write a script or small program to parse the XML looking for errors / issues. I'm wondering if anyone knows whether or not the XML schema for the MBSA reports is documented anywhere -- I have goggled this, and cant seem to find any trace of it. I've run across a few articles that address bits and pieces, but nothing that addresses the complete schema. Yes, I could just reverse engineer the XML, but I would like to understand a little more about the meaning of some of the tags. Thanks...

• How to ...set up new Java environment - largely interfaces...

  - by Chris Kimpton

  Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

• failover cluster file replication

  - by user156144

  I have a Windows 2008 R2 failover cluster server. I am going to move one of our window services onto this new server. The service writes some trace information to a log file on the local harddrive. This will become a problem when it is moved to cluster server when cluster A become unavailable and cluster B takes over and now there are 2 places where I need to look for log files. Is there a way to make sure regardless of which cluster is on, I get one complete log file? I have been researching this and there is something called DFS replication but i was wondering if there is something better that works with failover cluster... I prefer not having to update my code. I can specify it to write log files to a different location by changing app.config file but no code change...

• The power of explicit social networks

  - by me

  Last week I had the pleasure to write a guest post on the Oracle WebCenter blog  with the topic The Power of Social Recommendations where I described Implicit and Explicit Social Recommendations models and how they relate to a Social Engagement Strategy. Now let's look at a real live example. Apple has implemented an explicit Social Network model with So what ? Users do this already on Facebook and Twitter!  (see ZDNet blog post : Ping: Apple should leave social to Facebook, Twitter) BUT there are some major  advantages: "100 % control over the explicit Social Network ->  direct customer relationship without a social intermediary like Facebook or Twitter Total  access to the Social Graph ->  own the Social Graph data from their users and no need to "buy" it from external social network providers Integrated into the core business model ->  harvest all Social Graph data  to provide  highly personalized and trusted recommendations Isn't this the dream of any company which thinks about their social media strategy?  and guess what - Oracle Social Network is all about this - building explicit Social Networks with seamless integration into  your core business processes and applications follow me on twitter:  http://twitter.com/peterreiser Enterprise2.0, enterprise2.0, social networks, social media, apple

• Windows Azure Mobile Services: New support for iOS apps, Facebook/Twitter/Google identity, Emails, SMS, Blobs, Service Bus and more

  - by ScottGu

  A few weeks ago I blogged about Windows Azure Mobile Services - a new capability in Windows Azure that makes it incredibly easy to connect your client and mobile applications to a scalable cloud backend. Earlier today we delivered a number of great improvements to Windows Azure Mobile Services.  New features include: iOS support – enabling you to connect iPhone and iPad apps to Mobile Services Facebook, Twitter, and Google authentication support with Mobile Services Blob, Table, Queue, and Service Bus support from within your Mobile Service Sending emails from your Mobile Service (in partnership with SendGrid) Sending SMS messages from your Mobile Service (in partnership with Twilio) Ability to deploy mobile services in the West US region All of these improvements are now live in production and available to start using immediately. Below are more details on them: iOS Support This week we delivered initial support for connecting iOS based devices (including iPhones and iPads) to Windows Azure Mobile Services.  Like the rest of our Windows Azure SDK, we are delivering the native iOS libraries to enable this under an open source (Apache 2.0) license on GitHub.  We’re excited to get your feedback on this new library through our forum and GitHub issues list, and we welcome contributions to the SDK. To create a new iOS app or connect an existing iOS app to your Mobile Service, simply select the “iOS” tab within the Quick Start view of a Mobile Service within the Windows Azure Portal – and then follow either the “Create a new iOS app” or “Connect to an existing iOS app” link below it: Clicking either of these links will expand and display step-by-step instructions for how to build an iOS application that connects with your Mobile Service: Read this getting started tutorial to walkthrough how you can build (in less than 5 minutes) a simple iOS “Todo List” app that stores data in Windows Azure.  Then follow the below tutorials to explore how to use the iOS client libraries to store data and authenticate users. Get Started with data in Mobile Services for iOS Get Started with authentication in Mobile Services for iOS Facebook, Twitter, and Google Authentication Support Our initial preview of Mobile Services supported the ability to authenticate users of mobile apps using Microsoft Accounts (formerly called Windows Live ID accounts).  This week we are adding the ability to also authenticate users using Facebook, Twitter, and Google credentials.  These are now supported with both Windows 8 apps as well as iOS apps (and a single app can support multiple forms of identity simultaneously – so you can offer your users a choice of how to login). The below tutorials walkthrough how to register your Mobile Service with an identity provider: How to register your app with Microsoft Account How to register your app with Facebook How to register your app with Twitter How to register your app with Google The tutorials above walkthrough how to obtain a client ID and a secret key from the identity provider. You can then click on the “Identity” tab of your Mobile Service (within the Windows Azure Portal) and save these values to enable server-side authentication with your Mobile Service: You can then write code within your client or mobile app to authenticate your users to the Mobile Service.  For example, below is the code you would write to have them login to the Mobile Service using their Facebook credentials: Windows Store App (using C#): var user = await App.MobileService                     .LoginAsync(MobileServiceAuthenticationProvider.Facebook); iOS app (using Objective C): UINavigationController *controller = [self.todoService.client     loginViewControllerWithProvider:@"facebook"     completion:^(MSUser *user, NSError *error) {        //... }]; Learn more about authenticating Mobile Services using Microsoft Account, Facebook, Twitter, and Google from these tutorials: Get started with authentication in Mobile Services for Windows Store (C#) Get started with authentication in Mobile Services for Windows Store (JavaScript) Get started with authentication in Mobile Services for iOS Using Windows Azure Blob, Tables and ServiceBus with your Mobile Services Mobile Services provide a simple but powerful way to add server logic using server scripts. These scripts are associated with the individual CRUD operations on your mobile service’s tables. Server scripts are great for data validation, custom authorization logic (e.g. does this user participate in this game session), augmenting CRUD operations, sending push notifications, and other similar scenarios.   Server scripts are written in JavaScript and are executed in a secure server-side scripting environment built using Node.js.  You can edit these scripts and save them on the server directly within the Windows Azure Portal: In this week’s release we have added the ability to work with other Windows Azure services from your Mobile Service server scripts.  This is supported using the existing “azure” module within the Windows Azure SDK for Node.js.  For example, the below code could be used in a Mobile Service script to obtain a reference to a Windows Azure Table (after which you could query it or insert data into it):     var azure = require('azure');     var tableService = azure.createTableService("<< account name >>",                                                 "<< access key >>"); Follow the tutorials on the Windows Azure Node.js dev center to learn more about working with Blob, Tables, Queues and Service Bus using the azure module. Sending emails from your Mobile Service In this week’s release we have also added the ability to easily send emails from your Mobile Service, building on our partnership with SendGrid. Whether you want to add a welcome email upon successful user registration, or make your app alert you of certain usage activities, you can do this now by sending email from Mobile Services server scripts. To get started, sign up for SendGrid account at http://sendgrid.com . Windows Azure customers receive a special offer of 25,000 free emails per month from SendGrid. To sign-up for this offer, or get more information, please visit http://www.sendgrid.com/azure.html . One you signed up, you can add the following script to your Mobile Service server scripts to send email via SendGrid service:     var sendgrid = new SendGrid('<< account name >>', '<< password >>');       sendgrid.send({         to: '<< enter email address here >>',         from: '<< enter from address here >>',         subject: 'New to-do item',         text: 'A new to-do was added: ' + item.text     }, function (success, message) {         if (!success) {             console.error(message);         }     }); Follow the Send email from Mobile Services with SendGrid tutorial to learn more. Sending SMS messages from your Mobile Service SMS is a key communication medium for mobile apps - it comes in handy if you want your app to send users a confirmation code during registration, allow your users to invite their friends to install your app or reach out to mobile users without a smartphone. Using Mobile Service server scripts and Twilio’s REST API, you can now easily send SMS messages to your app.  To get started, sign up for Twilio account. Windows Azure customers receive 1000 free text messages when using Twilio and Windows Azure together. Once signed up, you can add the following to your Mobile Service server scripts to send SMS messages:     var httpRequest = require('request');     var account_sid = "<< account SID >>";     var auth_token = "<< auth token >>";       // Create the request body     var body = "From=" + from + "&To=" + to + "&Body=" + message;       // Make the HTTP request to Twilio     httpRequest.post({         url: "https://" + account_sid + ":" + auth_token +              "@api.twilio.com/2010-04-01/Accounts/" + account_sid + "/SMS/Messages.json",         headers: { 'content-type': 'application/x-www-form-urlencoded' },         body: body     }, function (err, resp, body) {         console.log(body);     }); I’m excited to be speaking at the TwilioCon conference this week, and will be showcasing some of the cool scenarios you can now enable with Twilio and Windows Azure Mobile Services. Mobile Services availability in West US region Our initial preview of Windows Azure Mobile Services was only supported in the US East region of Windows Azure.  As with every Windows Azure service, overtime we will extend Mobile Services to all Windows Azure regions. With this week’s preview update we’ve added support so that you can now create your Mobile Service in the West US region as well: Summary The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services. We’ll have even more new features and enhancements coming later this week – including .NET 4.5 support for Windows Azure Web Sites.  Keep an eye out on my blog for details as new features become available. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Crypto-Analysis of keylogger logs and config file. Possible?

  - by lost.

  Is there anyway Encryption on an unidentified file can be broken(file in question: config file and log files from ardamax keylogger). These files date back all the way to 2008. I searched everywhere, nothing on slashdot, nothing on google. Ardamax Keyviewer? Should I just write to Ardamax? I am at a loss of what to do. I feel comprimised. Anyone managed to decrpyt files with Crypto-analysis? More Information-- There are log files in the folder and a configuration file, "akv.cfg". Is it possible to decrypt the files and maybe getting the attackers email address used to receive the keylogger logs? I've Checked ardamax.com. They have an built-in log viewer. But its unavailable for download. If superuser isn't the proper place to ask, know where I might get help?

• How much system and business analysis should a programmer be reasonably expected to do?

  - by Rahul

  In most places I have worked for, there were no formal System or Business Analysts and the programmers were expected to perform both the roles. One had to understand all the subsystems and their interdependencies inside out. Further, one was also supposed to have a thorough knowledge of the business logic of the applications and interact directly with the users to gather requirements, answer their queries etc. In my current job, for ex, I spend about 70% time doing system analysis and only 30% time programming. I consider myself a good programmer but struggle with developing a good understanding of the business rules of a complex application. Often, this creates a handicap because while I can write efficient algorithms and thread-safe code, I lose out to guys who may be average programmers but have a much better understanding of the business processes. So I want to know - How much business and systems knowledge should a programmer have ? - How does one go about getting this knowledge in an immensely complex software system (e.g. trading applications) with several interdependent business processes but poorly documented business rules.

• Can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate?

  - by jt0dd

  There are many situations where the validity of the timestamp attached to a certain post (submission of information) might be invaluable for the post owner's legal usage. I'm not looking for a service to achieve this, as requested in this great question, but rather a method for the achievement of such a service. For the legal (in most any law system) authentication of text content and its submission time, the owner of the content would need to prove: that the timestamp itself has not been altered and was accurate to begin with. that the text content linked to the timestamp had not been altered I'd like to know how to achieve this via programming (not a language-specific solution, but rather the methodology behind the solution). Can a timestamp be validated to being accurate to the time that the content was really submitted? Can data be stored in a form that it can be read, but not written to, in a proven way? In other words, can I save & store a user's submission in a way that proves that the data has not been altered, and that the timestamp is accurate? I can't think of any programming method that would make this possible, but I am not the most experienced programmer out there. Based on MidnightLightning's answer to the question I cited, this sort of thing is being done. Clarification: I'm looking for a method (hashing, encryption, etc) that would allow an average guy like me to achieve the desired effect through programming. I'm interested in this subject for the purpose of Defensive Publication. I'd like to learn a method that allows an every-day programmer to pick up his computer, write a program, pass information through it, and say: I created this text at this moment in time, and I can prove it. This means the information should be protected from the programmer who writes the code as well. Perhaps a 3rd party API would be required. I'm ok with that.

• Can't make SELinux context types permanent with semanage

  - by Safado

  I created a new folder at /modevasive to hold my mod_evasive scripts and for the Log Directory. I'm trying to change the context type to httpd_sys_content_t so Apache can write to the folder. I did semanage fcontext -a -t "httpd_sys_content_t" /modevasive to change the context and then restorecon -v /modevasive to enable the change, but restorecon didn't do anything. So I used chcon to change it manually, did the restorecon to see what would happen and it changed it back to default_t. semanage fcontext -l gives: /modevasive/ all files system_u:object_r:httpd_sys_content_t:s0` And looking at /etc/selinux/targeted/contexts/files/file_contexts.local gives /modevasive/ system_u:object_r:httpd_sys_content_t:s0 So why does restorecon keep setting it back to default_t?

• SQL Server Snapshot Replication Subscriber (Editable or Read-Only)

  - by NateReid

  I need to create a copy of my SQL 2008 R2 Enterprise database and have it located on the same server as the original. I will be using this second copy of the database as the target of a mostly read-only website. I understand that if I create this copy of the database using snapshot replication that all data changes in the subscriber database will be overwriten in the event of the next replication. The web application will try to write to this database to record login attempts, etc and will fail if its source database is read-only. In my case I do not need to keep these auditing records and they can therefore be overwriten each time a new snapshot is applied. My question is whether SQL Server forces the subcriber database to be read-only and is there any way around this? Thank you, Nate
