• ROI in choosing a CMS solution

  - by Tio

  At the company I work for we need a CMS. The question is, what to choose, for me I think the best solution is to develop one of our own, but we ( my boss and I ), talked about using Drupal. But my boss is completely non-technical, and want's to take a lot of shortcut's which for programming is utterly bad. Too many shortcut's ( and that's why just last Friday we had a bug on one of our systems that caused a lot of panic ). So I'm trying to investigate on the ROI of using already existing CMS solutions VS developing our own customized CMS ( based on a open source library or not ). So that I can sell this to my boss. I'm almost sure that developing a customized CMS is the best for our small company. After a search on google I found this: Choose between a commercial, open source, or customized CMS, but the link is from 2003, it has some truth's, but the world changed a lot from 2003. But I can't seem to find anything else about it. I've developed my own CMS, so I know it's not the most easy thing to do, and that it takes time. Can someone give me any tips? EDIT: With CMS I mean Content Management System, to manage the webpages of our clients.

• crippling repeating "pciehp card not present" notifications

  - by Nanne

  When using ubuntu (12.04, both installed and on a live usb) I get a lot of these messages: pciehp 0000:00:1c.5:pcie04: Card not present on Slot(37) pciehp 0000:00:1c.5:pcie04: Card present on Slot(37) And with a lot I mean about 20 per second. This has a crippling effect, and I would like to get rid of it :) The computer is a packard bell easynote BG48-U-100 DC. I tip I picked up from some fedora/redhat error here was to look at lspci -vnn. I have pasted the part about "00:1c.5" here: http://pastebin.com/0sfsiqW2 For what good it may do, here is the lsmod of my machine: http://pastebin.com/DQZy1kAL From that first pastebin I think to conclude that it has to do with the module shpchp, which seems to me (aka: google) to have something to do with ACPI. That's as far as I've come in disecting this. Can anyone help me along further? What can I do, check etc? I did see this topic but my intentions are not to surpress the error message: I know how to do this (from that topic ;) ), but I'm looking for a real sollution. Finding the problem on the internet does suspect me to believe it is neither an ubuntu specific nor a packard-bell specific problem.If you google the problem it seems that is present on several other distribution/hardware combo's as well, and it looks like the advice is to remove one of the drivers? I have no clue as to which driver I should look at and and what would be the effect of just removing it. I have seen this topic which is old-ish, but describes my problem and is about a similar computer. The solution in this topic was to compile a new kernel using a spanish guide, which seems a bit extreme to me, so I'm kinda hoping for a better solution than that.

• Large enterprise application - clients wish to use duplicate e-mails addresses?

  - by Alex Key

  I'd like to know people's opinions, reactions to clients and technical work arounds (if applicable), to the issue of an enterprise application where a client wishes to use duplicate e-mail addresses? To clarify, when I say duplicate e-mail addresses I mean within the same client system, having multiple users that have the same e-mail address. So not just using generic e-mail addresses but using the e-mail address of another user. e.g. Bob Jenkins: [email protected] James Jeffery: [email protected] Context To give this some further context, in the e-learning sector it is common that although all staff in an organisation must complete e-learning - they may not have their own e-mail address so they choose to use their managers e-mail address. Albeit against good practice in public sites... it's a requirement we've over and over again where an organisation is split between office based staff and perhaps e.g. staff in a warehouse. Where problem lies Mr Steak, good point, the problem lies in password resets and perhaps in situations where semi-personal information could be sent (not confidential enough to worry about the insecurities of email). Perhaps reminders for specific system actions, which would be confusing for the unintended party to see (if perhaps misreading the e-mail's intended recipient) Possible solutions System knowing the difference between a "for the attention of" and direct to the person e-mails, including this in the body text. Using alternative communication such as SMS Simply not having e-mails sent to people who are not the intended recipient. Providing an e-mail service ourselfs (not really viable for a corporate IT dept) Thoughts?

• Oracle OpenWorld Session: “Business Driven Development with BPM: Lessons from the Real World”

  - by Ajay Khanna

  One of key values that BPM promises is “Business Empowerment”. People closest to the processes, who participate in the process every day, are the ones who know most about the process. These are the people who run day-to-day operations, people who triage customer issues, people who envision improvements and innovations. It is, therefore, imperative that when a company decides to use BPM technology to automate their business processes, business people take the driver’s seat. BPM is not an IT only project. Oracle BPM suite has been designed keeping this core tenet of BPM, Business Empowerment, in mind. The result is business user centered design of Process Composer. Process Composer is designed to let business users document their processes, analyze them using simulation, create web forms, specify business rules and even run them in testing mode using process player, to see if the designed process meets their needs. This does not mean that IT has no role in this process. In fact, Oracle BPM Suite has made it very easy for Business and IT to collaborate. The same process can be shared among business, and IT stakeholders and each can collaborate to create model-driven, process based executable applications. A process may need to integrate with multiple systems via various mechanisms, and IT leads system and data integration effort. IT helps fine tune the performance of process applications and ensures that the deployment of process application meets scalability and failover standards. In this session, we saw Harish Gaur and Satya Narayanan from Oracle demonstrate roles Business and IT play in BPM projects and how Oracle BPM Suite enables business and IT collaboration to design and automate process based applications. They also discussed real life customer stories. Some key takeaways from this session: There are no IT projects, only business initiatives, requiring IT support Identify high impact processes – critical, better BPM ROI Identify key metrics to measure process performance Align business with IT layer

• Showing Egde Shaped Event Duration in StreamInsight using Debugger

  Whilst writing some courseware I wanted to be able to see the start and end times of Edge shaped events from within the debugger.  A quick recap on Edge events At the start of the event you do not know the end time and most probably cannot work it out or you should be using one of the other shapes. You enqueue an event (Start Edge) with the start time and payload of the event.  The end time of the event is set to infinity When you see the end edge come through, you enqueue another event (End Edge) with the previous start time and payload and restate the event’s end time.  This is the Retract Event All seems simple enough.  The problem is the debugger is a little shy about showing you what you need but you can get it to show you everything by also reading this article Here’s what I mean. Here is what the Event Debugger looks like by default when viewing 2 complete edge events.  Notice how all the end times are set to infinity   The above does not tell you for how long an event was valid.  I then add the “NewEndTime” column to the debugger output and there I can now see the duration of events.  You will see the Retract events (End Edge) have the same start time and payload as their respective start events (Start Edge)   You can follow the exact same logic when looking at Interval shape events.  They look a little different on the output adapter but using this article you can easily see what is happening.

• Non-blocking ORM issues

  - by Nikolay Fominyh

  Once I had question on SO, and found that there are no non-blocking ORMs for my favorite framework. I mean ORM with callback support for asynchronous retrieval. The ORM would be supplied with a callback or some such to "activate" when data has been received. Otherwise ORM needs to be split of in a separate thread to guarantee UI responsiveness. I want to create one, but I have some questions that blocking me from starting development: What issues we can meet when developing ORM? Does word "non-blocking" before word "ORM" will dramatically increase complexity of ORM? Why there are not much non-blocking ORMs around? Update: It looks, that I have to improve my question. We have solutions that already allows us to receive data in non-blocking way. And I believe that not all companies that use such solutions - using raw SQL. We want to create more generic solution, that we can reuse in future projects. What difficulties we can meet?

• How do I force apt-get to install a package that will not install due to a bug introduced by Ubuntu 11.10?

  - by Hemm

  Ubuntu 11.10 separated out python-profiler from the Python standard library due to licensing philosophies. (According to what I could Google, correct me if I'm wrong.) This is an active bug since October for 11.10. I have Python 2.7.2 installed, so the dependency errors are wrong. 'apt-get check' does not resolve the problem. What is the best way to resolve to this? Thank you. sudo apt-get install python-profiler Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: python-profiler : Depends: python (>= 2.5) but it is not going to be installed Depends: python (< 2.8) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

• Compute the AES-encryption key given the plaintext and its ciphertext?

  - by Null Pointers etc.

  I'm tasked with creating database tables in Oracle which contain encrypted strings (i.e., the columns are RAW). The strings are encrypted by the application (using AES, 128-bit key) and stored in Oracle, then later retrieved from Oracle and decrypted (i.e., Oracle itself never sees the unencrypted strings). I've come across this one column that will be one of two strings. I'm worried that someone will notice and presumably figure out what those two values to figure out the AES key. For example, if someone sees that the column is either Ciphertext #1 or #2: Ciphertext #1: BF,4F,8B,FE, 60,D8,33,56, 1B,F2,35,72, 49,20,DE,C6. Ciphertext #2: BC,E8,54,BD, F4,B3,36,3B, DD,70,76,45, 29,28,50,07. and knows the corresponding Plaintexts: Plaintext #1 ("Detroit"): 44,00,65,00, 74,00,72,00, 6F,00,69,00, 74,00,00,00. Plaintext #2 ("Chicago"): 43,00,68,00, 69,00,63,00, 61,00,67,00, 6F,00,00,00. can he deduce that the encryption key is "Buffalo"? 42,00,75,00, 66,00,66,00, 61,00,6C,00, 6F,00,00,00. I'm thinking that there should be only one 128-bit key that could convert Plaintext #1 to Ciphertext #1. Does this mean I should go to a 192-bit or 256-bit key instead, or find some other solution? (As an aside, here are two other ciphertexts for the same plaintexts but with a different key.) Ciphertext #1 A ("Detroit"): E4,28,29,E3, 6E,C2,64,FA, A1,F4,F4,96, FC,18,4A,C5. Ciphertext #2 A ("Chicago"): EA,87,30,F0, AC,44,5D,ED, FD,EB,A8,79, 83,59,53,B7.

• One codebase - lots of hosted services (similar to a basecamp style service) - planning structure

  - by RickM

  We have built a service (PHP Based) for a client, and are now looking to offer it to other clients as a hosted service. For this example, think of it like a hosted forum service, where a client signs up on our site, and is given a subdomain or can use their own domain, and the code picks up the domain, checks it against a 'master' users table, and then loads the content as needed. I'm trying to work out the best way of handling multiple clients. At the moment I can only think of two options that would work: Option 1 - Have 1 set of database tables, but on each table have a column called 'siteid' - this would mean every query has to check the siteid. This would effectively work with just 1 codebase, and 1 database. Option 2 - Have 1 'master' database with all the core stuff such as the client details and their domain. Then when the systen checks the domain, it pulls the clients database details (username/password/dbname) from a table, and loads a second database. The issue here is security of the mysql server details, however it does have the benefit that they are running their own database instead of sharing one. Which option would I be better taking here, and why? Ideally I want it to be fairly easy to convert the 'standalone' script to the 'multi-domain' script as we're on a tight deadline.

• What's the best way to learn/increase problem-solving skills?

  - by tucaz

  Hi all! I'm not sure this is the right place to ask this question, neither if this is the right way to ask this question but I hope you help me if it is not. I work as a programmer since I was 15 (will be 24 next week) so learning programming logic was somehow natural during the course of my career and I think that it helped me to get pretty good problem-solving. One thing none of us (programmers) can deny is that programming logic helps us in a lot of fields outside computer programming. So I'd say it is a very valuable resource that one should learn. My girlfriend is not a programmer and graduated in college on a non related course (Foreign Relations) because she didn't know what to study back then. As the years passed she discovered that she liked Logistics and started to work with it almost two years ago. However, since she does not have a technical background (not even basic Math) she is really having a hard time with it. She is already trying to catch up with Math, but even simple questions/brain-teasers are hard to her. For example, trying to find the missing numbers of this sequence: 0, 1, 1, 2, 3, 5, 8, _, _, 34 and so on. We know that this is Fibonacci but if we didn't we would probably be able to get to the correct answer just by "guessing" (using our acquired problem-solving skills). I'm not sure if problem-solving skills or logic are the correct name for it, but this is what I mean: quick solve problems, brain-teasers, find patterns, have a "sharp" mind. So, the question is: what is the best way for someone to learn this kind of skills without being a programmer (or studying algorithms and such)? If you say it is a book, could you please recommend one? Thanks a lot!

• How to fix "Disk drive for /boot/efi is not ready or not present"?

  - by N.N.

  After I updated BIOS/UEFI version to 1101 on an Asus P8Z68-V PRO motherboard Ubuntu (11.10) did not boot. After POST all I saw was a black screen with a blinking cursor in the top left corner. I booted an Ubuntu 11.10 live-CD and set the flag for the 20 MB partition before my boot partition to "bios_grub". Then I was able to boot and login. But now every time I boot and Ubuntu loads I get the following message: Disk drive for /boot/efi is not ready or not present. Continue waiting or press s to skip or m for manual recovery. I am able to login if I choose to ignore it by pressing s, but what does this message mean? How can I fix what the message warns about? After logging in I have noticed that /boot/efi is empty. The following forum post speaks of the same issue ubuntuforums.org/showthread.php?t=1893030. Updating to the latest BIOS/UEFI - version 3203, did not have any effect on this issue.

• 12.10 upgrade broke brightness keys [closed]

  - by Chris Morgan

  I have been running Ubuntu (64-bit) on my HP 6710b laptop (Core 2 Duo with integrated graphics) for several years, and the backlight brightness keys have always worked. Since I upgraded to Ubuntu 12.10 earlier today, those keys do not work any more. The secondary function keys: Fn+F3: sleep; still works (and considerably faster than ever before!) Fn+F8: battery info; still works Fn+F9: reduce brightness; stopped working in 12.10 Fn+F10: increase brightness; stopped working in 12.10 It may also be worth while mentioning that X does not appear to be receiving the brightness events at all, or at least not sending them out further. (This I detected with a key logger I wrote for a Uni project, which uses X's Record extension; it is informed of the sleep and battery info keystrokes, but doesn't receive the brightness ones at all.) In the mean time, I know that I can use the Brightness & Lock settings screen to alter the brightness. (Wow! I can suddenly make my backlight darker than I could before—I can go right down to turning the backlight off, something I couldn't do before... but this model has a fairly dim screen, so I don't expect to use that much, if ever.) How can I get the brightness keys working again? This question is probably strongly related to I can't control my Brightness in HP Compaq 6710s.

• Unicode license

  - by Eric Grange

  Unicode Terms of use (http://www.unicode.org/copyright.html) state that any software that uses their data files (or a modification of it) should carry the Unicode license references. It seems to me that most Unicode libraries have functions to check if a character is a digit, a letter, a symbol, etc. ans so will contain a modification of the Unicode Data Files (usually in the form of tables). Does that mean the license applies and all applications that use such Unicode libraries should carry the license? I've checked around, and it appears very few Unicode software do carry the license, though arguable most of those that didn't carry the license were from companies that were members of the Unicode consortium (do they get license exemption?). Some (f.i. Mozilla) are only "Liaison Members", and while their software do not carry the license (AFAICT), they do obviously rely on data derived from those data files. Is Mozilla in breach of the license? Should we carry the license in all apps that include any form of advanced Unicode support? (ie. are bound to rely on the Unicode data files) Or is there some form of broad exemption? (since very very few software out there carries the license)

• design in agile process

  Recently I had an interview with dev team in a company. The team uses agile + TDD. The code exercise implements a video rental store which generates statement to calc total rental fee for each type of video (new release, children, etc) for a customer. The existing code use object like: Statement to generate statement and calc fee where big switch statement sits to use enum to determine how to calc rental fee customer holds a list of rentals movie base class and derived class for each type of movie (NEW, CHILDREN, ACTION, etc) The code originally doesn't compile as the owner was assumed to be hit by a bus. So here is what I did: outlined the improvement over object model to have better responsibility for each class. use strategy pattern to replace switch statement and weave them in config But the team says it's waste of time because there is no requirement for it and UAT test suite works and is the only guideline goes into architecture decision. The underlying story is just to get pricing feature out and not saying anything about how to do it. So the discussion is focused on why should time be spent on refactor the switch statement. In my understanding, agile methodology doesn't mean zero design upfront and such code smell should be avoided at the beginning. Also any unit/UAT test suite won't detect such code smell, otherwise sonar, findbugs won't exist. Here I want to ask: is there such a thing called agile design in the agile methodology? Just like agile documentation. how to define agile design upfront? how to know enough is enough? In my understanding, ballpark architecture and data contract among components should be defined before/when starting project, not the details. Am I right? anyone can explain what the team is really looking for in this kind of setup? is it design aspect or agile aspect? how to implement minimum viable product concept in the agile process in the real world project? Is it must that you feel embarrassed to be MVP?

• OOP implementation of BUFFS and Stats. Suggestion

  - by Mattia Manzo Manzati

  I am developing an MMORPG server using NodeJS. I am not sure how to implement Buffs, i mean, equipped objects or used skills have effects on the Player() which has many Stats(), some of them have a max cap... Effects can change the Stat value, increasing or decreasing it by a value, a percentage or completly rewrite the value of the stat. After a while I have decided to create a base class for buffs, which can be hidden (if they are casted from an equipped object) or shown if they came from an ability (Spell). Anyway I need suggestion how to implement it, use an array for all active buffs for a stat and have a function calculate the value of the stat affected by buffs each time I need the value of the stat or...? Other more OOP's ways to do it? I have read this What's a way to implement a flexible buff/debuff system? but this implements only a percentage system, which buffs can only say "+10%, +20%, etc...", but I would love to have an hybrid system, which can have percentage values or static values (like WoW does), and using modifiers it's hard to implement, because modifiers refers to the current value of stat :/ Thanks for suggestions :)

• What should a developer know before building a public web site?

  - by Joel Coehoorn

  What things should a programmer implementing the technical details of a web site address before making the site public? If Jeff Atwood can forget about HttpOnly cookies, sitemaps, and cross-site request forgeries all in the same site, what important thing could I be forgetting as well? I'm thinking about this from a web developer's perspective, such that someone else is creating the actual design and content for the site. So while usability and content may be more important than the platform, you the programmer have little say in that. What you do need to worry about is that your implementation of the platform is stable, performs well, is secure, and meets any other business goals (like not cost too much, take too long to build, and rank as well with Google as the content supports). Think of this from the perspective of a developer who's done some work for intranet-type applications in a fairly trusted environment, and is about to have his first shot and putting out a potentially popular site for the entire big bad world wide web. Also: I'm looking for something more specific than just a vague "web standards" response. I mean, HTML, JavaScript, and CSS over HTTP are pretty much a given, especially when I've already specified that you're a professional web developer. So going beyond that, Which standards? In what circumstances, and why? Provide a link to the standard's specification. This question is community wiki, so please feel free to edit that answer to add links to good articles that will help explain or teach each particular point. To search in only the answers from this question, use the inquestion:this option.

• Getting touchpad to work in desktop ubuntu

  - by kamziro

  I bought a small touchpad to stick on top of the keyboard, and it works fine on the windows computer, but not on my ubuntu desktop. I mean, when I do "xinput list" it shows the following: ? Virtual core pointer id=2 [master pointer (3)] ? ? Virtual core XTEST pointer id=4 [slave pointer (2)] ? ? PIXART USB OPTICAL MOUSE id=8 [slave pointer (2)] ? ? Logitech USB-PS/2 Optical Mouse id=11 [slave pointer (2)] ? ? Microsoft Wired Keyboard 600 id=13 [slave pointer (2)] ? ? Macintosh mouse button emulation id=14 [slave pointer (2)] ? ? Cirque Corporation 9925 AG Touchpad id=15 [slave pointer (2)] ? Virtual core keyboard id=3 [master keyboard (2)] ? Virtual core XTEST keyboard id=5 [slave keyboard (3)] ? Power Button id=6 [slave keyboard (3)] ? Power Button id=7 [slave keyboard (3)] ? No brand SP04-A1 id=9 [slave keyboard (3)] ? Elite Silicon USB Audio Device id=10 [slave keyboard (3)] ? Microsoft Wired Keyboard 600 id=12 [slave keyboard (3)] The Cirque Corporation touchpad (I'm assuming that's the component name) is the touchpad. Is there anything I'm missing?

• Calling a .NET C# class from XSLT

  - by HanSolo

  If you've ever worked with XSLT, you'd know that it's pretty limited when it comes to its programming capabilities. Try writing a for loop in XSLT and you'd know what I mean. XSLT is not designed to be a programming language so you should never put too much programming logic in your XSLT. That code can be a pain to write and maintain and so it should be avoided at all costs. Keep your xslt simple and put any complex logic that your xslt transformation requires in a class. Here is how you can create a helper class and call that from your xslt. For example, this is my helper class:  public class XsltHelper     {         public string GetStringHash(string originalString)         {             return originalString.GetHashCode().ToString();         }     }   And this is my xslt file(notice the namespace declaration that references the helper class): <?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:ext="http://MyNamespace">     <xsl:output method="text" indent="yes" omit-xml-declaration="yes"/>     <xsl:template  match="/">The hash code of "<xsl:value-of select="stringList/string1" />" is "<xsl:value-of select="ext:GetStringHash(stringList/string1)" />".     </xsl:template> </xsl:stylesheet>   Here is how you can include the helper class as part of the transformation: string xml = "<stringList><string1>test</string1></stringList>";             XmlDocument xmlDocument = new XmlDocument();             xmlDocument.LoadXml(xml);               XslCompiledTransform xslCompiledTransform = new XslCompiledTransform();             xslCompiledTransform.Load("XSLTFile1.xslt");               XsltArgumentList xsltArgs = new XsltArgumentList();                        xsltArgs.AddExtensionObject("http://MyNamespace", Activator.CreateInstance(typeof(XsltHelper)));               using (FileStream fileStream = new FileStream("TransformResults.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite))             {                 // transform the xml and output to the output file ...                 xslCompiledTransform.Transform(xmlDocument, xsltArgs, fileStream);                            }
