• Business Choices and Evony

  - by Robert May

  Recently, I’ve been playing a game called Evony, and I finally decided to quit the game and thought I should warn others who might be tempted.  I also find a lot of insight with this game as an example.  A few of the companies that I’ve worked with or worked for have been like this and they are NOT good places to be. Evony is a joke designed to milk as much money out of people as possible.  As a professional software developer who mentors teams on how to build better software, here's what I see: They obviously offshore all development and have little oversight over that offshore development, and they probably have a small team at that.  Evidenced by the poor grammar throughout the game. They're seeking to maximize revenue and pushing to do as little development as possible, which would mean a small team. They're horribly understaffed in the customer support department as evidenced by never replying to this forum and never responding to bug reports or help requests (I've had one open with no response AT ALL for over a month . . .) They have way inadequate testing, no CI, and probably no automated unit tests.  You can see this by the poor grammar throughout the game and the type of bugs that show up. They aren't following a formal development process (no Agile, Waterfall, or anything else) as evidenced by their lack of predictable release cycle and lack of visibility. I'm guessing that the internal code base is terrible, otherwise, there wouldn't be an "Age II" that had nothing more than a new visual interface and a few rule tweaks.  This is also evidenced by the itty bitty scope of bug fixes and their inability to really fix bugs. Their Architect sucks.  Really, 42k user is all you can handle on a single server?  Could you REALLY not come up with a better way to scale to handle users?  They've built isolated worlds, instead of a single continuous world. Back to milking people for money--to really progress, you have to spend money. All of this adds up to knowing, deliberate actions on the part of management.  They CHOOSE to do this (like AOL choosing to send more discs instead of improve quality). So, what can we learn? This game will never really improve, since the bosses don't care, they're only in it for the money. The game will never have good support.  Again, the owners don't care. Giving them money only perpetuates this scam (and yes, I've given them money, way too much money. :() They don't care if you quit.  There's a new sucker born every day. Don't EVER go to work for them.  I've worked both with and for people like this and the culture is NEVER good. Ah well. Technorati Tags: Evony

• Software Tuned to Humanity

  - by Phil Factor

  I learned a great deal from a cynical old programmer who once told me that the ideal length of time for a compiler to do its work was the same time it took to roll a cigarette. For development work, this is oh so true. After intently looking at the editing window for an hour or so, it was a relief to look up, stretch, focus the eyes on something else, and roll the possibly-metaphorical cigarette. This was software tuned to humanity. Likewise, a user’s perception of the “ideal” time that an application will take to move from frame to frame, to retrieve information, or to process their input has remained remarkably static for about thirty years, at around 200 ms. Anything else appears, and always has, to be either fast or slow. This could explain why commercial applications, unlike games, simulations and communications, aren’t noticeably faster now than they were when I started programming in the Seventies. Sure, they do a great deal more, but the SLAs that I negotiated in the 1980s for application performance are very similar to what they are nowadays. To prove to myself that this wasn’t just some rose-tinted misperception on my part, I cranked up a Z80-based Jonos CP/M machine (1985) in the roof-space. Within 20 seconds from cold, it had loaded Wordstar and I was ready to write. OK, I got it wrong: some things were faster 30 years ago. Sure, I’d now have had all sorts of animations, wizzy graphics, and other comforting features, but it seems a pity that we have used all that extra CPU and memory to increase the scope of what we develop, and the graphical prettiness, but not to speed the processes needed to complete a business procedure. Never mind the weight, the response time’s great! To achieve 200 ms response times on a Z80, or similar, performance considerations influenced everything one did as a developer. If it meant writing an entire application in assembly code, applying every smart algorithm, and shortcut imaginable to get the application to perform to spec, then so be it. As a result, I’m a dyed-in-the-wool performance freak and find it difficult to change my habits. Conversely, many developers now seem to feel quite differently. While all will acknowledge that performance is important, it’s no longer the virtue is once was, and other factors such as user-experience now take precedence. Am I wrong? If not, then perhaps we need a new school of development technique to rival Agile, dedicated once again to producing applications that smoke the rear wheels rather than pootle elegantly to the shops; that forgo skeuomorphism, cute animation, or architectural elegance in favor of the smell of hot rubber. I struggle to name an application I use that is truly notable for its blistering performance, and would dearly love one to do my everyday work – just as long as it doesn’t go faster than my brain.

• Questions about identifying the components in MVC

  - by luiscubal

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

• It is CX a new concept?

  - by Isabel F. Peñuelas

  The Marketing Industry and the Web Industry are talking about CX since some time. However it is only very recently that the concept has reached some common meaning accepted by the analysts’ and the IT community. The new CX model depends on two previous facts: the expansion of the social media, and the impact of the new advanced features of mobile devices regarding brand-customer interaction. CXsers vs UXers First there is some need of disambiguity between User Experience and Customer Experience. User Experience -UX, is a much well established concept related with the design of user interactions for particular devices. UX people are interested on multiple touch points of digital interfaces while CX people are interested on all kind of interfaces including physical ones. UX is an evolution of Web Usability, while CX is a marketing concept. UX is an instrument of User Experience. CX in fact is all about Connections and Interactions. Connections Dan Draper, the creative director Mad Men, understands very well that to market effectively means to connect with people, and the best way to connect to people is to use the connections people have with other people: understanding Social Media connections and taking the customer pulse of customers on those medias, and are strong facilitators of CX strategies.  Interactions We can very simply define CX as the relationship that a customer establishes with a brand through multiple touch points (interactions, channels) through the entire life cycle of his relationship- direct or indirect with the brand. Interactions can be grouped on Customer Journeys through multiple touch points defined as the path a customer follows to achieve a goal. Processes A customer journey today usually starts at the moment he surfs the Web, then he takes a purchase decision; purchases the product;  request a particular service and finally recommends or do not recommends the product.  Customer Journeys are processes, and to analyze customer journeys there exists today a broad offering of modern Customer Journey tools very similar actually to the use cases or UML activity diagrams for IT systems design. As a summary CX is nothing more and nothing less than applying process analysis methods for better understanding how to create value through customer interactions across the multiple user´s touch points with the brand.

• Sync Google Calendar with SharePoint Calendar

  - by dataintegration

  The ADO.NET Providers for Google and SharePoint make it easy to retrieve and update data in both Google's web services and SharePoint. This article shows how the SQL interface to data makes it easy to build applications that need to move data from one source to another. The application described here is a demo Windows application that synchronizes calendar events between Google and SharePoint, but the RSSBus Providers can be used to achieve integrations on both the .NET and the Java platforms, including more sophisticated features like full automation. Getting the Events Step 1: Google accounts can have several calendars. Obtain a list of a user's Google Calendars by issuing a query to the Calendars table. For example: SELECT * FROM Calendars. Step 2: In order to get a list of the events from a given Google Calendar, issue a query to the CalendarEvents table while specifying the CalendarId from the Calendars table. The resulting events can be further filtered by using the StartDateTime or EndDateTime columns. For example: SELECT * FROM CalendarEvents WHERE (CalendarId = '[email protected]') AND (StartDateTime >= '1/1/2012') AND (StartDateTime <= '2/1/2012') Step 3: SharePoint stores data in Lists. There are various types of lists, e.g., document lists and calendar lists. A SharePoint account can have several lists of the same type. To find all the calendar lists in SharePoint, use the ListLists stored procedure and inspect the BaseTemplate column. Step 4: The SharePoint data provider models each SharPoint list as a table. Get the events in a particular calendar by querying the table with the same name as the list. The events may be filtered further by specifying the EventDate or EndDate columns. For example: SELECT * FROM Calendar WHERE (EventDate >= '1/1/2012') AND (EventDate <= '2/1/2012') Synchronizing the Events Synchronizing the events is a simple process. Once the events from Google and SharePoint are available they can be compared and synchronized based on user preference. The sample application does this based on user input, but it is easy to create one that does the synchronization automatically. The INSERT, UPDATE, and DELETE statements available in both data providers makes it easy to create, update, or delete events as needed. Pre-Built Demo Application The executable for the demo application can be downloaded here. Note that this demo is built using BETA builds of the ADO.NET Provider for Google V2 and ADO.NET Provider for SharePoint V2, and will expire in 2013. Source Code You can download the full source of the demo application here. You will need the Google ADO.NET Data Provider V2 and the SharePoint ADO.NET Data Provider V2, which can be obtained here.

• Download files from a SharePoint site using the RSSBus SSIS Components

  - by dataintegration

  In this article we will show how to use a stored procedure included in the RSSBus SSIS Components for SharePoint to download files from SharePoint. While the article uses the RSSBus SSIS Components for SharePoint, the same process will work for any of our SSIS Components. Step 1: Open Visual Studio and create a new Integration Services Project. Step 2: Add a new Data Flow Task to the Control Flow screen and open the Data Flow Task. Step 3: Add an RSSBus SharePoint Source to the Data Flow Task. Step 4: In the RSSBus SharePoint Source, add a new Connection Manager, and add your credentials for the SharePoint site. Step 5: Now from the Table or View dropdown, choose the name of the Document Library that you are going to back up and close the wizard. Step 6: Add a Script Component to the Data Flow Task and drag an output arrow from the 'RSSBus SharePoint Source' to it. Step 7: Open the Script Component, go to edit the Input Columns, and choose all the columns. Step 8: This will open a new Visual Studio instance, with a project in it. In this project add a reference to the RSSBus.SSIS2008.SharePoint assembly available in the RSSBus SSIS Components for SharePoint installation directory. Step 9: In the 'ScriptMain' class, add the System.Data.RSSBus.SharePoint namespace and go to the 'Input0_ProcessInputRow' method (this method's name may vary depending on the input name in the Script Component). Step 10: In the 'Input0_ProcessInputRow' method, you can add code to use the DownloadDocument stored procedure. Below we show the sample code: String connString = "Offline=False;Password=PASSWORD;User=USER;URL=SHAREPOINT-SITE"; String downloadDir = "C:\\Documents\\"; SharePointConnection conn = new SharePointConnection(connString); SharePointCommand comm = new SharePointCommand("DownloadDocument", conn); comm.CommandType = CommandType.StoredProcedure; comm.Parameters.Clear(); String file = downloadDir+Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@File", file)); String list = Row.ServerUrl.ToString().Split('/')[1].ToString(); comm.Parameters.Add(new SharePointParameter("@Library", list)); String remoteFile = Row.LinkFilenameNoMenu.ToString(); comm.Parameters.Add(new SharePointParameter("@RemoteFile", remoteFile)); comm.ExecuteNonQuery(); After saving your changes to the Script Component, you can execute the project and find the downloaded files in the download directory. SSIS Sample Project To help you with getting started using the SharePoint Data Provider within SQL Server SSIS, download the fully functional sample package. You will also need the SharePoint SSIS Connector to make the connection. You can download a free trial here. Note: Before running the demo, you will need to change your connection details in both the 'Script Component' code and the 'Connection Manager'.

• Cron job running successfully suddenly reports script is not found

  - by Ted B

  What might cause cron to suddenly report a file it is supposed to run is "not found," when the file hasn't been touched, and in fact, the entire system hasn't been touched since it last ran successfully? I have a cronjob schedule I define by doing sudo crontab -e In it, I have dozens of cron jobs that run successfully.. I do not have a PATH specified, and I use absolute paths to call all my scheduled scripts, setting the PATH in them as needed. I do not specify a SHELL in the crontab. All scripts identify the shell as their first line. Without me touching the system, a particular job defined in the middle of other jobs will suddenly stop running. To debug this, I added an output redirection to a log file. In that, the output clearly shows the output of the script successfully running time after time for weeks, and then suddenly the following appears: /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found /bin/sh: /home/iupress/bin/sync-email_images: not found If I do the ls command, copying and pasting that exact path from the error message, it clearly reports the file is still there (no surprise). Yet the log continues to report that file is "not found" until I take action. I can run the script manually and it runs just fine. If I do sudo crontab -e and save the file, the job runs on the next scheduled time, putting its output in the log, no longer reporting the script is "not found". It seems to me the contents of the script trying to be run are irrelevant since cron doesn't even process the file because it is "not found". I have a job scheduled below the one that is encountering this problem that I know is continuing to run, because I have its output mailed to me. So I know cron is running and continues to run at least one other job, even after it suddenly reports this job's script is "not found". All my lines end with a newline. I had no periods in the crontab until I added the redirection to a log file. I have now added a PATH specification, but left the absolute paths in the jobs. Unfortunately, I have no idea if and when this problem will occur. It will likely be weeks from now. By the way, I am running a script to syncronize the clock, and I see the time is exactly what it should be.

• iTorque for a simple arcade game

  - by Herfus

  I have a basic understanding of programming, but I am no programmer. I've had a couple of a semesters with java programming, so we're talking pretty basic here. I have some scripting experience with game editors where I've created a few (simple) encounters, boss AI, abilities, events and so on. I've mostly done level design with UDK, Source and several other toolsets for a few years now, but I'd like to divert some of the focus to iphone-development. I've participated in a few development projects (source, udk, daot) where I've had a variety of roles (yet never beyond simple scripting). I have just finished prototyping an Iphone game (using game maker) and begun a bit more precise planning on what I'll have to do for the real version. The game is fairly simple, perhaps the best comparison in scope and complexity would be Doodlejump for iPhone. The reason I created the prototype was not just to answer a few questions about the gameplay, but to get some insight into what kind of problems I might face when trying to develop the real thing. I've been looking for engines that I can use for this. iTorque looks, so far, like the best option with a scripting language and WYSIWYG-editor. However the price is fairly steep and I'd like to prepare myself as much as possible before jumping into this, which is why I'm going to ask a few questions here. What kind of difficulties do you think I might run into, considering what you've read so far? Not just with torque, but development in general. I'm making this question mostly to have someone to reality check me. I usually achieve to do what I'm trying to do with scripting, but something tells me there's a very big difference between scripting an AI or an event and creating game logic. Will it be too much of a leap? Just how simple is it to use the Torque scripting language? Obviously I don't expect to be prepared, I expect it to be a learning process. However, I'd still like to be at least a bit confident on the time I'll have to dedicate to this first.

• Ubuntu is booting on acer e1-510 laptop, but screen displays nothing

  - by user287602

  Tried loading ubuntu 12.04 (32-bit as well 64 bit) through bootable usb , on a brand new 64-bit acer E1-510 laptop. It shows the 'Try ubuntu without installing screen' and I selected that option. But instead of showing ubuntu's logo(which implies it is loading). I get a blank screen. The screen is on, but it shows nothing. I tried the same on an old model laptop acer aspire 5738 and it worked like a charm. However, I realized that Ubuntu is actually booting on E1-510 and only the display is not working. How did I arrive at this conclusion? When I select on 'Try ubuntu without installing screen', after about 8-10 seconds I see that the WiFi indicator light on the laptop panel switches on(just like when we boot up a Windows OS or even Ubuntu ). I got an idea that the system booted Ubuntu. To confirm this, I tried to adjust volume using keyboard shortcuts. Voila, I can hear the sound of adjusting volume! That means it has already booted Ubuntu. I confirmed this with another step. I pressed the power button once and after two seconds I pressed ENTER. It began the process of switching off and within 5 seconds the laptop was powered off. You may ask, Why is this a confirmation that Ubuntu has booted? This is because in Ubuntu when you press on power button, a dialog box opens with shut down, restart, suspend option- and the shut down option is already selected by default; so all I have to do is press ENTER to shut down. This again proved that Ubuntu was indeed up and running. Unlike previous 'AskUbunutu' posts about Acer e1-510, I must mention that my laptop came WITH the Legacy BIOS mode, so its not really a problem to boot ubuntu from a bootable pendrive. Only the screen is not working. In case you need to know, I am running Windows 7-Ultimate 64 bit on acer e1-510.

• Java EE 8 update

  - by delabassee

  Planning for Java EE 8 is now well underway. As you know, a few weeks ago, we conducted a three part Java EE 8 Community Survey (you can find the final summary here). The data gathered have been very influential for the next steps. You can now expect over the coming weeks and months to see updates on the various specifications that compose the Java EE platform. Some Specification Leads are busy gathering additional feedback regarding what they should focus their efforts on (e.g. CDI 2 survey). Other Specification Leads have already publicly exposed what they think should be one of the focus for the evolution of the specification they lead.  For example, adding Server-Senet Events (SSE) support in JAX-RS is being discussed here and adding MVC support is being discussed here. Please remember that the fact we are now discussing any feature does not insure that it will be included in the proposal, nor in any particular update to Java EE. We can expect additional enhancements, changes and evolutions as we get closer to the finalisation of the different specifications... and there is still a long way to go with these specification proposals! Linda DeMichiel, Java EE Co-Specification Lead, has recently posted a draft proposal for the Java EE 8 Platform specification. Linda's goal is to recruit people and companies supporting this proposal before submitting it to the JCP.  This draft proposal is very interesting reading as it contains relevant information on the plans for Java EE 8 such as : The themes: Support for the latest web standards (eg. HTTP 2.0)  Continue to work on ease of development Improve the infrastructure for cloud support Alignment with Java SE 8 New JSRs to be added to the platform: J-Cache Java API for JSON Binding Java Configuration Plans for the Web Profile Plans on technologies to prune in Java EE 8, ... So if you haven't done it yet, I really encourage you to read the Java EE 8 draft proposal! Our goal for the Java EE 8 specification is for it to be finalized in the second half of 2016. It is important to note that we are in the early days of Java EE 8 and at this stage everything (themes, content, timing, etc.) is preliminary. Everything still needs to be discussed, challenged and agreed within the different Java Community Process (JCP) Experts Groups (EGs). Some EGs that still need to be formed! It could also means that the roadmap will have to be adjusted to follow the progress being made in the different EGs. This is also a good occasion to remind you that participation within those upcoming JCP Experts Groups is encouraged. Contributing in an EG is an effective lever to influence what Java EE 8 will become! Finally, as things get more concrete, we will share details on how to engage in the different Java EE 8 related Adopt-a-JSR initiatives, another way to contribute. You can also read other posts related to Java EE 8, here at The Aquarium blog. Just look for articles with the 'javaee8' tag.

• Why is my laptop so sluggish? Or Damn You Facebook and Twitter! Or All Hail Chrome!

  - by John Conwell

  In the past three weeks, I've noticed that my laptop (dual core 2.1GHz, 2Gb RAM) has become amazingly sluggish.  I only uses for communications and data lookup workflows, so the slowness was tolerable.  But today I finally got fed up with the suckyness and decided to get to the root of the problem (I do have strong performance roots after all). It actually didn't take all that long to figure it out.  About a year ago I converted to Google Chrome (away from FireFox).  One of the great tools Chrome has is a "Task Manager" tool, that gives you Windows Task Manager like details for all the tabs open in the browser (Shift + Esc).  Since every tab runs in its own process, its easy from Task Manager (both Windows or Chrome) to identify and kill a single performance offending tab.  This is unlike IE, where you only get aggregate data about all tabs open.  Anyway, I digress.  Today my laptop sucked.  Windows Task Manager told me that I had two memory hogging Chrome tabs, but couldn't tell me which web page those tabs are showing.  Enter Chrome Task Manager which tells you the page title, along with CPU, memory and network utilization of each tab.  Enter my amazement.  Turns out Facebook was using just shy of half a Gb of RAM.  Half a Gigabyte!  That's 512 Megabytes!524,288 Kilobytes! 536,870,912 Bytes!  Or 4,294,967,296 Bits!  In other words, that's a frackin boat load of memory.  Now consider that Facebook is running on pretty much 96.3% (statistics based on absolutely nothing) of every house hold desktop, laptop, netbook, and mobile device in America, that is pretty horrific! And I wasn't playing any Facebook games like FarmWars or MafiaVille.  I just had my normal, default home page up showing me who just had breakfast, or just got finished with their morning run. I'm sorry...let me say that again...HALF A GIG OF RAM!  That is just unforgivable. I can just see my mom calling me up:  Mom: "John...I think I need a new computer.  Mine is really slow these days" John: "What do you have running?" Mom: "Oh, just Facebook" John: "Ok, close Facebook and tell me how fast your computer feels" Mom: "Well...I don't know how fast it is.  All I do is use Facebook" John: "Ok Mom, I'll send you a new computer by Tuesday" Oh yea...and the other offending web page?  It was Twitter, using a quarter of a Gigabyte. God I love social networks!

• What are the drawbacks of sending XML to browsers and let them apply XSLT?

  - by MainMa

  Context Working as a freelance developer, I often made websites completely based on XSLT. In other words, on every request, an XML file is generated, containing everything we need to know about the page content: the name of the user currently logged in, the top menu entries, if this menu is dynamic/configurable, the text to display in a specific area of the page, etc. Then XSL process (caches, etc.) it to HTML/XHTML page to send to the browser. It has a good point to make it easier to create small-scale websites, especially with PHP. It is a sort of template engine, but which I prefer to other template engines because it's much more powerful than most of template engines, and because I know it better and like it. It is also possible, when need, to give an access to raw XML data on demand for an automated access, without the need to create separate APIs. Of course, it will fail completely on any medium-scale or large-scale website, since, even with good caching techniques, XSL still degrades overall website performance and requires more CPU serverside. Question Modern browsers have the ability to take an XML file and to transform it with an associated XSL file declared in XML like <?xml-stylesheet href="demo.xslt" type="text/xsl"?>. Firefox 3 can do it. Internet Explorer 8 can do it too. It means that it is possible to migrate XSL processing from the server to the client side for 50% of users (according on browser statistics on several websites where I may want to implement this). It means that those 50% of users will receive only the XML file at each request, thus reducing their and server's bandwidth (XML file being much shorter than its processed HTML analog), and reducing server's CPU usage. What are the drawbacks of this technique? I thought about several ones, but it doesn't apply in this situation: Difficult implementation and the need to choose, based on the browser request, when to send raw XML and when to transform it to HTML instead. Obviously, the system will not be much more difficult then the actual one. The only change to make is to add XSL file link to every XML, and to add a browser check. More IO and bandwidth usage, since the XSLT file will be downloaded by the browsers, instead of being cached by the server. I don't think it will be a problem, since XSLT file will be cached by the browsers (like images, or CSS, or JavaScript files are cached actually). Possibly some problems on client side, like maybe problems when saving a page in some browsers. Difficulty to debug code: it is impossible to obtain an HTML source the browser is actually using, since the only displayed source is the downloaded XML. On the other hand, I rarely go look at HTML code on client side, and in most cases, it is unusable directly (whitespace being removed).

• Can't install alternate CD from USB?

  - by mattias

  Hi im trying to install ubuntu 12.04 with full hard disk encryption. After downloading and installing the Ubuntu live CD, I learned that truecrypt doesnt support full disk encryption on linux. I also learned that the best way to get "nearly full disk encryption" on ubuntu is by installing it from the alternate install CD. I tried that, but something is wrong with my CD reader/burner so it doesnt boot up when i insert the cd. My thought here was to take the .iso that I downloaded on my unencrypted Ubuntu system, use Unetbootin to make the usb drive. The usb drive used for this is exactly the same brand as one that I know has worked with a previous ubuntu live system on the same computer. I also used unetbootin for that usb, but I created it from windows that time. The usb stick boots up fine and i get through the first couple of steps in the installation process. However, After a while I get a "box" with the following error message "Load Installer components from CD" There was a problem reading data from the CD-ROM. Please make sure it is in the drive. If retrying does not work, you should check the integrity of your CD-ROM. "Failed to copy file from CD-ROM. Retry? " Then I cant get any further. I googled a lot and found this page which seems to tackle this very problem: http://www.dotkam.com/2010/11/29/ins...mage-from-usb/ I tried to do what it said. After pressing TAB, I wrote : cdrom-detect/try-usb=true without quotes because that's what i think is right. When I press TAB, there already is a text saying : /ubnkern initrd=/ubninit vga=788 -- quiet which can be removed. I have tried to both delete the text before the "--" and just inserting cdrom-detect/try-usb=true before it. Any idea of what can be wrong? I would like to do a full system encryption, or as full as it is possible. I dont want to just encrypt my /home folder. Maybe this isn't the easiest way. I use SanDisk usb sticks. I know there is a problem with U3 launcher on some SanDisks, but I never had to remove U3 before from similar disks, and the alternate install does boot up, so I dont think using U3 removal would help me. Any help or indication to an easier way to do this would be appreciated

• Representing complex object dependencies

  I have several classes with a reasonably complex (but acyclic) dependency graph. All the dependencies are of the form: class X instance contains an attribute of class Y. All such attributes are set during initialization and never changed again. Each class' constructor has just a couple parameters, and each object knows the proper parameters to pass to the constructors of the objects it contains. class Outer is at the top of the dependency hierarchy, i.e., no class depends on it. Currently, the UI layer only creates an Outer instance; the parameters for Outer constructor are derived from the user input. Of course, Outer in the process of initialization, creates the objects it needs, which in turn create the objects they need, and so on. The new development is that the a user who knows the dependency graph may want to reach deep into it, and set the values of some of the arguments passed to constructors of the inner classes (essentially overriding the values used currently). How should I change the design to support this? I could keep the current approach where all the inner classes are created by the classes that need them. In this case, the information about "user overrides" would need to be passed to Outer class' constructor in some complex user_overrides structure. Perhaps user_overrides could be the full logical representation of the dependency graph, with the overrides attached to the appropriate edges. Outer class would pass user_overrides to every object it creates, and they would do the same. Each object, before initializing lower level objects, will find its location in that graph and check if the user requested an override to any of the constructor arguments. Alternatively, I could rewrite all the objects' constructors to take as parameters the full objects they require. Thus, the creation of all the inner objects would be moved outside the whole hierarchy, into a new controller layer that lies between Outer and UI layer. The controller layer would essentially traverse the dependency graph from the bottom, creating all the objects as it goes. The controller layer would have to ask the higher-level objects for parameter values for the lower-level objects whenever the relevant parameter isn't provided by the user. Neither approach looks terribly simple. Is there any other approach? Has this problem come up enough in the past to have a pattern that I can read about? I'm using Python, but I don't think it matters much at the design level.

• How do I take responsibility for my code when colleague makes unnecessary improvements without notice?

  - by Jesslyn

  One of my teammates is a jack of all trades in our IT shop and I respect his insight. However, sometimes he reviews my code (he's second in command to our team leader, so that's expected) without a heads up. So sometimes he reviews my changes before they complete the end goal and makes changes right away... and has even broken my work once. Other times, he has made unnecessary improvements to some of my code that is 3+ months old. This annoys me for a few reasons: I am not always given a chance to fix my mistakes He has not taken the time to ask me what I was trying to accomplish when he is confused, which could affect his testing or changes I don't always think his code is readable Deadlines are not an issue and his current workload doesn't require any work in my projects other than reviewing my code changes. Anyways, I have told him in the past to please keep me posted if he sees something in my work that he wants to change so that I could take ownership of my code (maybe I should have said "shortcomings") and he's not been responsive. I fear that I may come off as aggressive when I ask him to explain his changes to me. He's just a quiet person who keeps to himself, but his actions continue. I don't want to banish him from making code changes (not like I could), because we are a team--but I want to do my part to help our team. Added clarifications: We share 1 development branch. I do not wait until all my changes complete a single task because I risk losing some significant work--so I make sure my changes build and do not break anything. My concern is that my teammate doesn't explain the reason or purpose behind his changes. I don't think he should need my blessing, but if we disagree on an approach I thought it would be best to discuss the pros and cons and make a decision once we both understand what is going on. I have not discussed this with our team lead yet as I would prefer to resolve personal disagreements without getting management involved unless it is necessary. Since my concern seemed more of personal issue than a threat to our work, I chose to not bother the team lead. I am working on code review process ideas--to help promote the benefits of more organized code reviews without making it all about my pet peeves.

• Small hiccup with VMware Player after upgrading to Ubuntu 12.04

  The upgrade process Finally, it was time to upgrade to a new LTS version of Ubuntu - 12.04 aka Precise Pangolin. I scheduled the weekend for this task and despite the nickname of Mauritius (Cyber Island) it took roughly 6 hours to download nearly 2.400 packages. No problem in general, as I have spare machines to work on, and it was weekend anyway. All went very smooth and only a few packages required manual attention due to local modifications in the configuration. With the new kernel 3.2.0-24 it was necessary to reboot the system and compared to the last upgrade, I got my graphical login as expected. Compilation of VMware Player 4.x fails A quick test on the installed applications, Firefox, Thunderbird, Chromium, Skype, CrossOver, etc. reveils that everything is fine in general. Firing up VMware Player displays the known kernel mod dialog that requires to compile the modules for the newly booted kernel. Usually, this isn't a big issue but this time I was confronted with the situation that vmnet didn't compile as expected ("Failed to compile module vmnet"). Luckily, this issue is already well-known, even though with "Failed to compile module vmmon" as general reason but nevertheless it was very easy and quick to find the solution to this problem. In VMware Communities there are several forum threads related to this topic and VMware provides the necessary patch file for Workstation 8.0.2 and Player 4.0.2. In case that you are still on Workstation 7.x or Player 3.x there is another patch file available. After download extract the file like so: tar -xzvf vmware802fixlinux320.tar.gz and run the patch script as super-user: sudo ./patch-modules_3.2.0.sh This will alter the existing installation and source files of VMware Player on your machine. As last step, which isn't described in many other resources, you have to restart the vmware service, or for the heart-fainted, just reboot your system: sudo service vmware restart This will load the newly created kernel modules into your userspace, and after that VMware Player will start as usual. Summary Upgrading any derivate of Ubuntu, in my case Xubuntu, is quick and easy done but it might hold some surprises from time to time. Nonetheless, it is absolutely worthy to go for it. Currently, this patch for VMware is the only obstacle I had to face so far and my system feels and looks better than before. Happy upgrade! Resources I used the following links based on Google search results: http://communities.vmware.com/message/1902218#1902218http://weltall.heliohost.org/wordpress/2012/01/26/vmware-workstation-8-0-2-player-4-0-2-fix-for-linux-kernel-3-2-and-3-3/ Update on VMware Player 4.0.3 Please continue to read on my follow-up article in case that you upgraded either VMware Workstation 8.0.3 or VMware Player 4.0.3.

• Proper Usage of Arrays and Functions [closed]

  - by Ssegawa Victor

  Can some one help me write a C code that solves the following problem. PROBLEM Consider the faculty registrar who has to process results for 1st year 1st semester students. Students offer five courses CSC 1100, CSK 1101, CSC 1104, CSC 1105 and CSC 1106. The courses have credit units 4,4,4,3 and 3 respectively. Lecturers provide course work and exam marks. For each course, course work constitutes 40% of the final mark while the exam constitutes 60% of the final mark. The role of the registrar is to Compute the final mark for each student for each course. The final mark must be a whole number Compute the grade and grade point of the students for each course they offered. According to senate regulations, grades and grade points are awarded to final marks according to the following criteria Range Grade Grade Point 90 – 100 A+ 5.0 80 – 89 A 5.0 75 – 79 B+ 4.5 70 – 74 B 4.0 65 – 69 C+ 3.5 60 – 64 C 3.0 55 – 59 D+ 2.5 50 – 54 D 2.0 45 – 49 E 1.5 40 – 44 E- 1.0 0 – 39 F 0.0 Put a comment ‘Retake’ to a student for every course where the Grade Point is less than 2.0 Compute the cumulative grade point average CGPA for each student. The senate formula for CGPA is GGPA =(?_(i=1)^(i=N)¦?CU _i×GP _i ?)/(?_(i=1)^(i=N)¦CU i) Put a comment “Progress” for any student whose GGPA is greater than 2 and “Stay Put” on a student whose CGPA is less than 2 You are required to create a c program that considers a class of 25 students and: 1.Initializes an array ‘student’ which stores student names 2.Initializes arrays for course work and exam for each course. ‘cw_csc_1100’ and ‘ex_csc_1100’ store course work and exam marks (respectively) for CSC 1100. The same approach is considered for all other courses 3.Initializes the coursework and exam marks arrays with marks between 0 and 99 4.Write appropriate functions that will generate the final marks, generate grades, generate grade points, generate cumulative grade points, generate comments for students and comments for courses per student 5.Create appropriate arrays for final marks and insert the data there using the appropriate functions 6.Without having to create any extra arrays, use the functions created to generate a report per student that looks like the one bellow. Student Name: Ngubiri Course Unit Final mark Grade Grade Point Course Comment CSC 1100 43 E- 1.0 Retake CSK 1101 50 D 2.0 CSC 1104 59 D+ 2.5 CSC 1105 70 B 4.0 CSC 1106 65 C+ 3.5 CGPA 2.47 Overall Comment Progress NB It is advisable that the indices are used to identify the owners. Eg if student[x] is John, then cs_csc_100[x] should be a mark for John since the index is the same

• Does the method of adjustment matter, or just the final calibration?

  - by Steve

  A company produces software (and hardware) that is used to both perform automatic adjustments on electronic test equipment as well as perform calibrations of the same equipment. The results of the calibrations are put onto a certificate of calibration that is sent to the customer along with the equipment. This calibration certificate states various conditions of the calibration, such as what hardware (models/serial numbers) and software (version) was used to perform the calibration, as well as things like environmental conditions, etc. Making the assumption that the software used to produce the data (and listed on the calibration certificate) used on the certificate of calibration must have gone through a "test/release" process and must be considered "released" software - does this also mean that the software used for adjustment must also be released? I believe that the method (software/environmental conditions/etc) used or present during adjustment doesn't matter, all that really matters is the end result of the calibration, the conditions present during the calibration, and whether or not the equipment was within the specifications. The real question I'm hoping to get answered: Is there a reputable source (e.g. NIST or somewhere similar) that addresses this question? (I have searched...) The thinking is that during high volume production runs, the "unreleased" system can be used to perform adjustments, as long as a released system is used to perform the calibrations, since the time required to perform the adjustments is much longer than the calibration. This unreleased system will eventually become released for use, but currently is not. Also, please not that there is a distinction between "adjustment" and "calibration". The definition from BIPM International vocabulary of metrology, 2.39: Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or secondary standard) and, in a second step, uses this information to establish a relation for obtaining a measurement result from an indication. Followed by NOTE 2 (emphasis in original text): Calibration should not be confused with adjustment of a measuring system, often mistakenly called "self-calibration", nor with verification of calibration As a side note, I'm not sure why this got down voted. It's regarding software and it's use before and after release for use. I believe there is a best practice that can be applied and this is (hopefully) not primarily opinion based.

• SEO effects of intermix of WP blog, custom PHP site and FB app game

  - by melbournetechlover

  We're a melbourne tech company in the process of building a custom site in PHP. We plan to launch a "pre-launch" page which is also custom coded (CSS3 on twitter bootstrap framework + HTML5 front end and PHP back end). On that site will be a link to a blog - the idea behind this is to build up ranking for a variety of relevant keywords prior to the full site going live (given the majority of the site is a member only community anyway so the blog is really the main way we'll be able to execute on-site SEO. Ideally, we would like to install wordpress in a subdirectory on our servers and just customise the header to look the same as the landing page of the website. But some questions and concerns... Is there any detrimental effect on SEO efforts in having two separate systems (one custom PHP, the other an installation of wordpress) to manage the blog vs the rest of the site? Are there any benefits or detriments to installing on a sub domain such as blog.sitename.com vs. sitename.com/blog. My preference would be sitename.com/blog as it feels neater - but open to suggestions based on knowledge of Google preferences. Separately, we are building a Facebook app which is under another site name. Again because we are launching this app first, from an SEO perspective, would it actually be better to run it from a sub domain on the main site - e.g. gamename.mainsitename.com instead of on app.gamename.com? Currently we have it on app.gamename.com, but if there are SEO benefits to moving it to the other domain and server then we'll do it. Basically we don't want to have our SEO efforts divided - will Google algorithms prefer two sites heavily referring traffic, or is it better to focus our efforts on one. I guess that's the crux of the issue. But the other one is - does Google care about traffic accessing a page built for the Facebook app iFrame - does that count toward rankings? Sorry I hope these questions aren't too complex - but we're in the tech world every day and still can't seem to find a good answer to these ones...hence I'm taking to the forums!! Free beer for whoever can give me a solid answer!

• Accessing SQL Server data from iOS apps

  - by RobertChipperfield

  Almost all mobile apps need access to external data to be valuable. With a huge amount of existing business data residing in Microsoft SQL Server databases, and an ever-increasing drive to make more and more available to mobile users, how do you marry the rather separate worlds of Microsoft's SQL Server and Apple's iOS devices? The classic answer: write a web service layer Look at any of the questions on this topic asked in Internet discussion forums, and you'll inevitably see the answer, "just write a web service and use that!". But what does this process gain? For a well-designed database with a solid security model, and business logic in the database, writing a custom web service on top of this just to access some of the data from a different platform seems inefficient and unnecessary. Desktop applications interact with the SQL Server directly - why should mobile apps be any different? The better answer: the iSql SDK Working along the lines of "if you do something more than once, make it shared," we set about coming up with a better solution for the general case. And so the iSql SDK was born: sitting between SQL Server and your iOS apps, it provides the simple API you're used to if you've been developing desktop apps using the Microsoft SQL Native Client. It turns out a web service remained a sensible idea: HTTP is much more suited to the Big Bad Internet than SQL Server's native TDS protocol, removing the need for complex configuration, firewall configuration, and the like. However, rather than writing a web service for every app that needs data access, we made the web service generic, serving only as a proxy between the SQL Server and a client library integrated into the iPhone or iPad app. This client library handles all the network communication, and provides a clean API. OSQL in 25 lines of code As an example of how to use the API, I put together a very simple app that allowed the user to enter one or more SQL statements, and displayed the results in a rather primitively formatted text field. The total amount of Objective-C code responsible for doing the work? About 25 lines. You can see this in action in the demo video. Beta out now - your chance to give us your suggestions! We've released the iSql SDK as a beta on the MobileFoo website: you're welcome to download a copy, have a play in your own apps, and let us know what we've missed using the Feedback button on the site. Software development should be fun and rewarding: no-one wants to spend their time writing boiler-plate code over and over again, so stop writing the same web service code, and start doing exciting things in the new world of mobile data!

• What to do when opensource project starts to tear apart? (or a manager tries to write code and than shouts at the team)

  - by Kabumbus

  Imagine there is an open source cross-platform project on Google code. It has lots of revisions (1000). It concentrates in itself lots technological stuff - rare stuff - it mixes top tech. It contains server, and more than one client. The project was created by a well-connected team of developers (friends) and a manager that was sponsoring project at its start up during its first few months (project now is more than a year old-sponsoring oss project is a big good deal- also gave the idea of project to developers). The project was growing in complexity and effort reqiered to continue development. Once upon a time a manager - team leader started trying to write code (he was a programmer in some other projects - not the best, but he felt like he was one). He started because one of the developers suggested an idea at the team meeting and he felt he just needed to do it on his own. He failed, and he told the dev team about it. The dev team did what he failed to do in a few days. After that, the manager feels that team codes with out him perfectly and gets the job done in short time. He felt sorry and lost and he started to crash like an old bad PC. Firstly, he started to scream (in forms of messages not in voice) he tried to tell developers that what they were doing was a bad, not-needed thing - developers kindly told him that his "beginnings" were not compilable while dev team product worked as needed. He told the developers that all work they do should be firstly discussed with him. Here is the part where we need to mention that all team members are "project owners" and logically have equal rights. The team leader suggested to the developers these options: change their dev process to go through him, or be moved from project owners to contributers. So what are our options as developers? What arguments we can provide to the team leader/manager for him to calm down? Is it possible to save the project or is it better to fork out now? An important issue is that lately we had no active ticket system, and I personally think that this was the reason the mess appeared. So... any ideas?

• Managing accounts on a private website for a real-life community

  - by Smudge

  Hey Pro Webmasters, I'm looking at setting-up a walled-in website for a real-life community of people, and I was wondering if anyone has any experience with managing member accounts for this kind of thing. Some conditions that must be met: This community has a set list of real-life members, each of whom would be eligible for one account on the website. We don't expect or require that they all sign-up. It is purely opt-in, but we anticipate that many of them would be interested in the services we are setting up. Some of the community members emails are known, but some of them have fallen off the grid over the years, so ideally there would be a way for them to get back in touch with us through the public-facing side of the site. (And we'd want to manually verify the identity of anyone who does so). Their names are known, and for similar projects in the past we have assigned usernames derived from their real-life names. This time, however, we are open to other approaches, such as letting them specify their own username or getting rid of usernames entirely. The specific web technology we will use (e.g. Drupal, Joomla, etc) is not really our concern right now -- I am more interested in how this can be approached in the abstract. Our database already includes the full member roster, so we can email many of them generated links to a page where they can create an account. (And internally we can require that these accounts be paired with a known member). Should we have them specify their own usernames, or are we fine letting them use their registered email address to log-in? Are there any paradigms for walled-in community portals that help address security issues if, for example, one of their email accounts is compromised? We don't anticipate attempted break-ins being much of a threat, because nothing about this community is high-profile, but we do want to address security concerns. In addition, we want to make the sign-up process as painless for the members as possible, especially given the fact that we can't just make sign-ups open to anyone. I'm interested to hear your thoughts and suggestions! Thanks!

• How do you automate a SharePoint 2010 deployment?

  - by Enrique Lima

  In the last couple of months SharePoint traffic (consulting, training and speaking) has picked up.  And with that also the requests for deployments.  There are good, great, bad and really bad things around this. But that is for another topic.  However part of the good and great has been the fact of organizations wanting to do a proof of concept deployment (even when WSS or MOSS has been deployed). We can go through a session (Microsoft has the SDPS concept, SharePoint Deployment Planning Services) of discovering what the customer wants to achieve from their investment in the platform and then also proceed to model the solution that would fit their needs.  But it should not stop there.  The next step should be a POC (as many have requested) to test out. Now, on to the meat of this post.  How do I deploy?  While it is a good process to watch and see all of it take place, not many have the time to sit through that.  Even more so, when that has been part of the description of deploying the platform in the sessions mentioned above. I will, though, break it into a deployment for development purposes and a deployment of a farm. Two tools (or scripts) for those two different types of deployment. First, let me address the development environment.  Around the last week in October, Chris Johnson (SharePoint Product Team) announced a SharePoint Easy Setup for Developers.  The kit itself will assist you in installing SharePoint Server (in standalone mode), the tools that go around Visual Studio, Expression Studio and the Office 2010 tools. Here is the link to Chris’ post: http://blogs.msdn.com/b/cjohnson/archive/2010/10/28/announcing-sharepoint-easy-setup-for-developers.aspx The other scenario is the use of a script in assisting you through the deployment of a farm. Now, this is not to override planning.  It should highlight the need for planning even more.  How?  Having your service accounts planned, the structure of the sites and the scale of your deployment.  Enter AutoSPInstaller.  This is a CodePlex project, and the intent behind this is not only to automate the installation but to give some meaning and get some sense out of what goes on during a SharePoint deployment. How?  Take for example the creation of the databases, when we do the initial OOB deployment by using the wizard, more times than not, we leave the names as they are.  How is that a “bad thing”?  Let’s make it a better practice to rename those Databases, and have them take on a name that is not “GUID-ized”. Having a better naming convention will not hurt, on the other hand will allow for consistency. Here is the link to AutoSPInstaller’s site on CodePlex: http://autospinstaller.codeplex.com/
