• syslog ip ranges to specific files using `rsyslog`

  - by Mike Pennington

  I have many Cisco / JunOS routers and switches that send logs to my Debian server, which uses rsyslogd. How can I configure rsyslogd to send these router / switch logs to a specific file, based on their source IP address? I do not want to pollute general system logs with these entries. For instance: all routers in Chicago (source ip block: 172.17.25.0/24) to only log to /var/log/net/chicago. all routers in Dallas (source ip block 172.17.27.0/24) to only log to /var/log/net/dallas. Finally, these logs should be rotated daily for up to 30 days and compressed. NOTE: I am answering my own question

• What You Said: How You Find New Books

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your tips and tricks for finding fresh books to enjoy. Now we’re back with tips ranging from the old school to the digital. SJ highlights several of the most popular web-based tools for finding new books: Goodreads.com is quick and easy. Yournextread.com is fun and helps a lot. But I gotta be honest, Amazon’s suggestions are probably the most useful to me. TheFu suggests checking out award-winning lists and one rather quirky way to pick a good Sci-Fi book: For scifi, see Hugo winning books. Life is too short to read bad books. Sometimes that leads to an author with an entire series of books to enjoy. I really enjoy some of the scifi from the 40s and 50s. Wells stuff is always timeless too (and free). I’m less happy with Nebula winners–-different type of writers and not my personal taste.

• Firmware/driver for Broadcom wifi card, PowerBook G4 running Ubuntu 12.04 [duplicate]

  - by user107831

  This question already has an answer here: How to Install Broadcom Wireless Drivers 40 answers This is my first time working with Ubuntu (or Linux), so please be patient. I am running Ubuntu 12.04-powerpc "Precise Pangolin" on a Mac PowerBook G4 with 1.67GHz processor. The firmware/driver for the wifi card is missing. For reasons not worth explaining, I cannot physically plug the computer into the network. I have another computer, a MacBook Pro running OSX, from which I can download files and port them by USB thumb drive. The wifi card in the PowerBook G4 is by Broadcom. The chip is BCM4306, rev. 3. The PCI number is 14e4:4302. I have downloaded b43-fwcutter_015-14_powerpc.deb and dropped it into the Home folder on the Ubuntu machine. However, it will not install. When I double-click, it opens with Ubuntu SoftwareCenter, but the "Install" button is inactive: I can't click it. There's a message beside the inactive button saying, "An older version of 'b43-fwcutter' is available in your normal software channels. Only install this file if you trust the origin." If I "right-click" the .deb file and open with Archive Manager, it shows me the "DEBIAN" and "usr" folders, but I'm unsure what to do from there...and fairly certain this is not the right way to do things. Maybe I have the wrong version of b43-fwcutter for my machine/version of Ubuntu? The documentation for this problem is a mess. It refers to all sorts of out-of-date Ubuntu versions and to an array of different "cutter" and firmware files. Maybe I'd be able to figure this out if I were a more seasoned Ubuntu user, but I have no idea why Sofware Center won't let me do the install. I would be VERY grateful for an explanation of how to get the wifi card working on this machine again. Thank you!

• PeopleSoft 8.52 iPad Certification

  - by Dave Bain

  One of the real gems in the PeopleTools 8.52 release is the certification of PeopleSoft applications running in the Safari Browser on an iPad.  It is nice that PeopleSoft is not constrained by technology like Adobe Flex/Flash, so announcements like this "Adobe drops plans for mobile Flash support" do not limit our mobile solution to custom mobile development. There are parts of PeopleSoft applications that operate better on iPads than others.  One of the best is Workcenters.  Workcenters were new to PeopleTools 8.51 and we are starting to see more and more adoption of them.  Workcenters are roll based landing pages that eliminate difficult navigation by providing access to most links, pages, and reports a user in a role needs.  One of the nicest I’ve seen is the Supply Manager Workspace.  Here are some links to screenshots of what a WorkCenter looks like on an iPad: Here's the standard PeopleSoft Login Page The Supply Manager Workspace looks great full screen on an iPad iPad has a great user interface to zoom, here's a screenshot of an upclose view of an analytic. Touch one of the analytics and it drills into the details. Go ahead and give it a try.  WorkCenters and Dashboards are starting to show up across applications.  For a quick one to try, navigate to the PeopleTools->Integration Broker->Integration Network WorkCenter.  It’s new in PeopleTools 8.52.

• Collision Detection with SAT: False Collision for Diagonal Movement Towards Vertical Tile-Walls?

  - by Macks

  Edit: Problem solved! Big thanks to Jonathan who pointed me in the right direction. Sean describes the method I used in a different thread. Also big thanks to him! :) Here is how I solved my problem: If a collision is registered by my SAT-method, only fire the collision-event on my character if there are no neighbouring solid tiles in the direction of the returned minimum translation vector. I'm developing my first tile-based 2D-game with Javascript. To learn the basics, I decided to write my own "game engine". I have successfully implemented collision detection using the separating axis theorem, but I've run into a problem that I can't quite wrap my head around. If I press the [up] and [left] arrow-keys simultaneously, my character moves diagonally towards the upper left. If he hits a horizontal wall, he'll just keep moving in x-direction. The same goes for [up] and [left] as well as downward-diagonal movements, it works as intended: http://i.stack.imgur.com/aiZjI.png Diagonal movement works fine for horizontal walls, for both left and right-movement However: this does not work for vertical walls. Instead of keeping movement in y-direction, he'll just stop as soon as he "enters" a new tile on the y-axis. So for some reason SAT thinks my character is colliding vertically with tiles from vertical walls: http://i.stack.imgur.com/XBEKR.png My character stops because he thinks that he is colliding vertically with tiles from the wall on the right. This only occurs, when: Moving into top-right direction towards the right wall Moving into top-left direction towards the left wall Bottom-right and bottom-left movement work: the character keeps moving in y-direction as intended. Is this inherited from the way SAT works or is there a problem with my implementation? What can I do to solve my problem? Oh yeah, my character is displayed as a circle but he's actually a rectangular polygon for the collision detection. Thank you very much for your help.

• How can I correlate a wall jack to a user/machine on the domain?

  - by harryfino

  After reading Valve's new employee handbook, I was really interested in setting up a company map like they described on page 6: "The fact that everyone is always moving around within the company makes people hard to find. That’s why we have http://user — check it out. We know where you are based on where your machine is plugged in, so use this site to see a map of where everyone is right now." What I'm trying to figure out is: how I can tell which machine or domain user (either will do) is connected to a particular wall jack?

• Personalized Pricing

  - by David Dorf

  In past postings I've spent a fair amount of time talking about targeted promotions.  Using a complete view of the customer that includes purchase history, location history, and psychographics gleaned from social media, we can select the offer with the greatest chance of redemption.  This is done to influence shopping behavior, which might be introducing the consumer to a new product line, increasing their basket size, increasing frequency of purchases, etc. Safeway seems to be taking a slightly different approach with their personalized pricing.  In additional to offering electronic coupons and club card offers, they are also providing a personalized price for certain items based on purchase history.  So when Sally want to shop at Safeway, she first checks the "Just for U" website for three types of deals.  She starts by selecting manufacturer coupons to load into her loyalty card, then she checks the Club Card for offers like "buy one get one free." The third step is the interesting one.  Safeway will set a particular lower price for Sally good for 90 days on items she buys often.  Clearly this isn't enforcing a new behavior but rather instilling loyalty.  I would love to know exactly how they are determining the personalized price.  Of course bargain hunters can still stack the three offers so they can, for example, get their $4.99 Oatmeal for $0.72. I like this particular question and answer from their website's FAQ: My offers are not that great. Can I tell you what offers I need? That's a good idea. That functionality is not currently available, but we appreciate your input and are constantly improving our just for U program. Stay tuned for exciting enhancements! I suppose if Safeway is tracking all the purchases, they can easily determine whether the customer if profitable.  As long as the customer stays profitable, why not let them determine a few offers themselves?  Food for thought.

• Is having functionality in DB a road block to scalability?

  - by Estefany Velez

  I may not be able to give the right title to the question. But here it is, We are developing financial portal for wealth management. We are expecting over 10000 clients to use the application. The portal calculates various performance analytics based on the the technical analysis of the stock market. We developed lot of the functionality through Stored procedures, user defined functions, triggers etc. through Database. We thought we can gain huge performance boost doing stuff directly in database than through C# code. And we actually did get a huge performance boost. When I tried to brag about the achievement to our CTO, he counter questioned my decision of having functionality implemented in database rather than code. According to him such applications suffer scalability problems. In his words "These days things are kept in memory/cache. Clustered data is hard to manage over time. Facebook, Google have nothing in database. It is the era of thin servers and thick clients. DB is used only to store plain data and functionality should be completely decoupled from the database." Can you guys please give me some suggestions as to whether what he says is right. How to go about architect such an application?

• organizing images by resolution with batch files

  - by Anthony

  Doing some digging I'm trying to figure out a command line solution for organizing very large archives of images based on their resolution into folders, 1920x1080, 1600x1200, 1600x900, etc. I've come across a few post on Superuser mentioning something called ImageMagick, is that the best method to the madness I'm trying to accomplish? I've never used any command line functions/applets/tools other then those that come from Microsoft. I'm rather new to command line usage but ive been enjoying the hell out of it using Powershell, xcopy and robocopy. I am slowly trying to push myself further into the Linux world with Ubuntu running on one of my physical machines as well as a virtual machine so that's an option as well.

• Reconstruct a file from a TCP stream

  - by Abhishek Chanda

  I have a client and a server and a third box which sees all packets from the server to the client (but not the other way around). Now when the client requests a file from the server (over HTTP), the third box sees the response. I am trying to reconstruct the file there. I am using libpcap to capture TCP datagrams and trying to reconstruct the file there. Here is what I did Listen for packets on an interface Group all packets which have the same ACK number Sort the group based on SEQ number Extract data from each packet and combine them and write to the disk The problem is, the file thus generated is not exactly the same as the original file. Does everything sound correct here? Some more details: I am using C++ The packet data is being stored as std::vector<char> I did change the byte order while reading the ack number and seq number from the packet using ntohl I am not sure if I need to change the byte order for the data as well. I tried to reverse the data from each packet before combining them, even that did not work. Is there something I am missing?

• Write permission when mounting Windows shares from Ubuntu

  - by Ola Tuvesson

  I think I'm close to having my dev environment set up exactly the way I want, but one final snag remains. I'm running VirtualBox on a Windows 7 64bit host, with my dev enviroment inside a Ubuntu 12.04 guest. I want to keep the files for my projects on the host filesystem - partly so I can access them when the Ubuntu guest is not running, but also so I can use Tortoise and other Windows based tools (cough Photoshop), and it also eases my backup scheme somewhat. So I've got a folder "Rails" on my NTFS drive, which I've shared from the host with a user specifically created for the Ubuntu guest. The mount point has been set up and an entry added to fstab (cifs), using a credentials file and the options iocharset=utf8,file_mode=0777,dir_mode=07??77 This mounts fine and my Ubuntu user has both read and write permissions to the contents, but when I try to start my Rails app I get permission errors on any files the app needs to write to (e.g. the log file). What gives?

• How to verify that all files are intact prior to install?

  - by Kalle H. Väravas

  I'm working on my CMS (in PHP platform) for a long time now. The main program is done and I'm currently developing the Installer part. Installation itself will be fairly simple: Upload all files Verify that the "content/" dir has correct permissions Check if ALL files are intact and not modified [This is the subject of this question] Insert the config data and first settings Run install (Generate all DB tables and insert sample data etc.) Now the question-mark is at step 3. How do I verify ALL files? Verification itself should compare all CMS root-directories files against a list from remote location. List should contain filename, filesize and filetype. This way the user can check, that there are no unnecessary or corrupted files, that could indicated a breach in the software. I have seen some software installers do that, but I cannot find any right now and there for I'm clueless on the most optimal method for this. Of course there always is a simple array trick, but there surely must be a better and faster method?!

• How to represent an agile project to people focused on waterfall [closed]

  - by ahsteele

  Our team has been asked to represent our development efforts in a project plan. No one is unhappy with our work or questioning our ability to deliver, we are just participating in an IT cattle call for project plans. Trouble is we are an agile team and haven't thought about our work in terms of a formal project plan. While we have a general idea of what we are working on next we aren't 100% sure until we plan an iteration. Until now our team has largely operated in a vacuum and has not been required to present our methodology or metrics to outside parties. We follow most of the practices espoused in Extreme Programming. We hold quarterly planning meetings to have a general idea of the stories we are going to work on for a quarter. That said, our stories are documented on 3x5 cards and are only estimated at the beginning of the iteration in which they are going to be worked. After estimation we document the story in Team Foundation Sever. During an iteration, we attach code to stories and mark stories as completed once finished. From this data we are able to generate burn down and velocity charts. Most importantly we know our average velocity for an iteration keeping us from biting off more than we can chew. I am not looking to modify the way we do development but want to present our development activities in a report that someone only familiar with waterfall will understand. In What Does an Agile Project Plan Look Like, Kent McDonald does a good job laying out the differences between agile and waterfall project plans. He specifies the differences in consumable bullets: An agile project plan is feature based An Agile Project Plan is organized into iterations An Agile Project Plan has different levels of detail depending on the time frame An Agile Project Plan is owned by the Team Being able to explain the differences is great, but how best to present the data?

• Prepared statement alternatives for this middle-man program?

  - by user2813274

  I have an program that is using a prepared statement to connect and write to a database working nicely, and now need to create a middle-man program to insert between this program and the database. This middle-man program will actually write to multiple databases and handle any errors and connection issues. I would like advice as to how to replicate the prepared statements such as to create minimal impact to the existing program, however I am not sure where to start. I have thought about creating a "SQL statement class" that mimics the prepared statement, only that seems silly. The existing program is in Java, although it's going to be networked anyways so I would be open to writing it in just about anything that would make sense. The databases are currently MySQL, although I would like to be open to changing the database type in the future. My main question is what should the interface for this program look like, and does doing this even make sense? A distributed DB would be the ideal solution, but they seem overly complex and expensive for my needs. I am hoping to replicate the main functionality of a distributed DB via this middle-man. I am not too familiar with sql-based servers distributing data (or database in general...) - perhaps I am fighting an uphill battle by trying to solve it via programming, but I would like to make an attempt at least.

• Making Modular, Reusable and Loosely Coupled MVC Components

  - by Dusan

  I am building MVC3 application and need some general guidelines on how to manage complex client side interaction between my components. Here is my definition of one component in general way: Component which has it's own controller, model and view. All of the component's logic is placed inside these three parts and component is sort of "standalone", it contains it's own form, data needed for interaction, updates itself with Ajax and so on. Beside this internal logic and behavior of the component, it needs to be able to "Talk" to the outside world. By this I mean it should provide data and events (sort of) so when this component gets embedded in pages can notify other components which then can update based on the current state and data. I have an idea to use client ViewModel (in java-script) which would hookup all relevant components on page and control interaction between them. This would make components reusable, modular - independent of the context in which they are used. How would you do this, I am a bit stuck as I do not know if this is a good approach and there is a technical possibility to achieve this using java-script/jquery. The confusing part is about update via Ajax, how to ensure that component is properly linked to ViewModel when component is Ajax updated (or even worse removed or dynamically added). Also, how should this ViewModel be constructed and which technicalities to use here and in components to work as synergy??? On the web, I have found the various examples of the similar approach, but they are oversimplified (even for dummies) or over specific and do not provide valuable resource or general solution for this kind of implementation. If you have some serious examples it would be, also, very helpful. Note: My aim is to make interactions between many components on the same page simpler and more robust and elegant.

• need help upgrading small business wifi network

  - by Henry Jackson

  Our small business currently has 3 wireless access points around the building, each with their own SSID. Security is done with WEP (ick) and MAC address filtering (double ick). We are trying to reconfigure the setup, with these goals: wifi roaming between the access points user-based authentication that isn't as annoying as MAC address filtering. 1) The entire building is hardwired with ethernet, so I assume it should be easy to set up the routers to act as one big network, but I can't figure out how. Can someone point me in the right direction? The routers are consumer-grade linksys routers, is it possible to do this without getting new hardware? 2) For security, we will probably upgrade to WPA2, and I'm thinking of using the Enterprise version so that users can log in with a username, instead of having a single key (so if an employee leaves or something, their access can be removed). We have several on-site Windows servers, can one of them be set up as a RADIUS server, or is that best left to a dedicated machine (again, using existing hardware is good).

• Tender vs. Requirements vs. Solution Design

  - by Tom Tom

  Conventionally, which of the above documents is deemed to hold the most weight when it comes to system acceptance? I recently had a conversation along these lines: It was argued that the initial requirements / tender documentation should be used to determine system acceptance. It was said that the solution design only serves to describe the way in which the system will solve the problem, not the problem it will solve. Furthermore, it was argued that if requirements are missed during solution design, the requirements should be referenced during system acceptance and that if any requirements were missed then the original tender should be referenced. Conversely, I suggested that - while requirements may be based on the original tender - they supersede it once agreed with the stakeholders. Furthermore, during solution design, analysis is performed to address and refine these initial requirements, translating them into a system capable of meeting the actual requirements. Once signed off by the relevant users, this solution design should absolutely represent the requirements (by virtue of the fact that it's designed upon them) but actually supersedes them as the basis for system acceptance. Is one of the above arguments more valid than the other?

• Google results show .info domain instead of .com

  - by user481913

  I am on shared hosting currently and i registered this account with a .info domain as the main domain.... say MyDomain.info . However, the site runs from MyDomain.com . This is a cpanel based shared hosting account. MyDomain.info has nothing hosted at all... i.e no content files... MyDomain.com is setup as an Add On Domain and run from /public_html/MyDomain under MyDomain.info The problem is that when i type MyDomain as the keyword for search in Google , it shows result(s)for Mydomain.info although this is not the intended site and has no content hosted on itself. I tried to solve the issue by issuing a 301 permanent redirect from MyDomain.info to MyDomain.com, however Google keeps on displaying results as mydomain.info as the main site even after 1 month of the redirect. I want google to index MyDomain.com as the main site and remove MyDomain.info from the results. Also is this harmful from the seo point of view? How can i improve the seo if it is?

• Software Design Idea for multi tier architecture

  - by Preyash

  I am currently investigating multi tier architecture design for a web based application in MVC3. I already have an architecture but not sure if its the best I can do in terms of extendability and performance. The current architecure has following components DataTier (Contains EF POCO objects) DomainModel (Contains Domain related objects) Global (Among other common things it contains Repository objects for CRUD to DB) Business Layer (Business Logic and Interaction between Data and Client and CRUD using repository) Web(Client) (which talks to DomainModel and Business but also have its own ViewModels for Create and Edit Views for e.g.) Note: I am using ValueInjector for convering one type of entity to another. (which is proving an overhead in this desing. I really dont like over doing this.) My question is am I having too many tiers in the above architecure? Do I really need domain model? (I think I do when I exposes my Business Logic via WCF to external clients). What is happening is that for a simple database insert it (1) create ViewModel (2) Convert ViewModel to DomainModel for Business to understand (3) Business Convert it to DataModel for Repository and then data comes back in the same order. Few things to consider, I am not looking for a perfect architecure solution as it does not exits. I am looking for something that is scalable. It should resuable (for e.g. using design patterns ,interfaces, inheritance etc.) Each Layers should be easily testable. Any suggestions or comments is much appriciated. Thanks,

• Book Review&ndash;Getting Started With OAuth 2.0

  - by Lori Lalonde

  Getting Started With OAuth 2.0, by Ryan Boyd, provides an introduction to the latest version of the OAuth protocol. The author starts off by exploring the origins of OAuth, along with its importance, and why developers should care about it. The bulk of this book involves a discussion of the various authorization flows that developers will need to consider when developing applications that will incorporate OAuth to manage user access and authorization. The author explains in detail which flow is appropriate to use based on the application being developed, as well as how to implement each type with step-by-step examples. Note that the examples in the book are focused on the Google and Facebook APIs. Personally, I would have liked to see some examples with the Twitter API as well. In addition to that, the author also discusses security considerations, error handling (what is returned if the access request fails), and access tokens (when are access tokens refreshed, and how access can be revoked). This book provides a good starting point for those developers looking to understand what OAuth is and how they can leverage it within their own applications. The book wraps up with a list of tools and libraries that are available to further assist the developer in exploring the APIs supporting the OAuth specification. I highly recommend this book as a must-read for developers at all levels that have not yet been exposed to OAuth. The eBook format of this book was provided free through O'Reilly's Blogger Review program.
