• How can I be prepared to join a company?

  - by Aerovistae

  There's more to it than that, but this title was the best way I could think of to sum it up. I'm a senior in a good computer science program, and I'm graduating early. About to start interviews and all whatnot. I'm not a super-experienced programmer, not one of those people who started in middle school. I'm decent at this, but I'm not among the best, not nearly. I have to do an awful lot of googling. So today I'm meeting some fellow for lunch at a campus cafe to discuss some front-end details when this tall, good-looking guy begs pardon, says he's new to campus, says he's wondering if we know where he can go to sign up for recruiting developers. Quickly evolves into long conversation: he's the CEO of a seems-to-be-doing-well start-up. Hiring passionate interns and full-times. Sounds great! I take one look at his site on my own computer later, immediately spot a major bug. No idea how to fix it, but I see it. I go over to the page code, and good god. It's the standard amount of code you would expect from a full-scale web application, a couple dozen pages of HTML and scripts. I don't even know where to start reading it. I've built sites from scratch, but obviously never on that scale, nor have I ever worked on one of that scale. I have no idea which bit might generate the bug. But that sets me thinking: How could someone like me possibly settle into an environment like that? A start-up is a very high-pressure working environment. I don't know if I can work at that pace under those constraints-- I would hate to let people down. And with only 10 employees, it's not like anyone has much time to help you get your bearings. Somewhere in there is a question. Can you see it? I'm asking for general advice here. Maybe even anecdotal advice. Is joining a start-up right out of college a scary process? Am I overestimating what it would take to figure out the mass of code behind this site? What's the likelihood a decent but only moderately-experienced coder could earn his pay at such a place? For instance, I know nothing of server-side/back-end programming. Never touched it. That scares me.

• Image first loaded, then it isn't? (XNA)

  - by M0rgenstern

  I am very confused at the Moment. I have the following Class: (Just a part of the class): public class GUIWindow { #region Static Fields //The standard image for windows. public static IngameImage StandardBackgroundImage; #endregion } IngameImage is just one of my own classes, but actually it contains a Texture2D (and some other things). In another class I load a list of GUIButtons by deserializing a XML file. public static GUI Initializazion(string pXMLPath, ContentManager pConMan) { GUI myGUI = pConMan.Load<GUI>(pXMLPath); GUIWindow.StandardBackgroundImage = new IngameImage(pConMan.Load<Texture2D>(myGUI.WindowStandardBackgroundImagePath), Vector2.Zero, 1024, 600, 1, 0, Color.White, 1.0f, true, false, false); System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); myGUI.Windows = pConMan.Load<List<GUIWindow>>(myGUI.GUIFormatXMLPath); System.Console.WriteLine("Windows loaded"); return myGUI; } Here this line: System.Console.WriteLine("Image loaded? " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Prints "true". To load the GUIWindows I need an "empty" constructor, which looks like that: public GUIWindow() { Name = ""; Buttons = new List<Button>(); ImagePath = ""; System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); //Image = new IngameImage(StandardBackgroundImage); //System.Console.WriteLine( //Image.IsActive = false; SelectedButton = null; IsActive = false; } As you can see, I commented lines out in the constructor. Because: Otherwise this would crash. Here the line System.Console.WriteLine("Image loaded? (In win) " + (GUIWindow.StandardBackgroundImage.ImageStrip != null)); Doesn't print anything, it just crashes with the following errormessage: Building content threw NullReferenceException: Object reference not set to an object instance. Why does this happen? Before the program wants to load the List, it prints "true". But in the constructor, so in the loading of the list it prints "false". Can anybody please tell me why this happens and how to fix it?

• Enterprise with eyes on NoSQL

  - by thegreeneman

  Since joining Oracle a few months back, I have had the fortune of being able to interact with a number of large enterprise organizations and discuss their current state of adoption for NoSQL database technology.   It is worth noting that a large percentage of these organizations do have some NoSQL use and have been steadily increasing their understanding of its applicability for certain data management workloads.   Thru those discussions I’ve learned that it seems one of the biggest issues confronting enterprise adoption of NoSQL databases is the lack of standards for access, administration and monitoring.    This was not so much of an issue with the early adopters of NoSQL technology because they employed a highly DevOps centric approach to application deployment leaving a select few highly qualified developers with the task of managing the production of the system that they designed and implemented. However, as NoSQL technology moves out of the startup and into the hands of larger corporate entities, developers with a broad skill set that are capable of both development and I.T. type production management are in short supply and quickly get moved on to do new projects, often moving to different roles within the company.  This difference in the way smaller more agile startups operate as compared to more established companies is revealing a gap in the NoSQL technology segment that needs to get addressed.    This is one of places that a company such as Oracle has a leg up in the NoSQL Database front.  A combination of having gone thru a past database maturization process,  combined with a vast set of corporate relationships that have grown hand in hand to solve these types of issues, Oracle is in a great place to lead the way in closing the requirements gap for NoSQL technology.  Oracle's understanding of the needs specific to mature organizations have already made their way into the Oracle’s NoSQL Database offering with features such as:  One click cluster deployment with visual topology planning,  standards based monitoring protocols such as SNMP, support for data access for reporting via standard SQL  and integration with emerging standards for data access such as MapReduce.  Given the exciting developments we’re driving in the Oracle NoSQL Database group, I will have a lot more to say about this topic as we move into the second half of the year.

• What arguments can I use to "sell" the BDD concept to a team reluctant to adopt it?

  - by S.Robins

  I am a bit of a vocal proponent of the BDD methodology. I've been applying BDD for a couple of years now, and have adopted StoryQ as my framework of choice when developing DotNet applications. Even though I have been unit testing for many years, and had previously shifted to a test-first approach, I've found that I get much more value out of using a BDD framework, because my tests capture the intent of the requirements in relatively clear English within my code, and because my tests can execute multiple assertions without ending the test halfway through - meaning I can see which specific assertions pass/fail at a glance without debugging to prove it. This has really been the tip of the iceberg for me, as I've also noticed that I am able to debug both test and implementation code in a more targeted manner, with the result that my productivity has grown significantly, and that I can more easily determine where a failure occurs if a problem happens to make it all the way to the integration build due to the output that makes its way into the build logs. Further, the StoryQ api has a lovely fluent syntax that is easy to learn and which can be applied in an extraordinary number of ways, requiring no external dependencies in order to use it. So with all of these benefits, you would think it an easy to introduce the concept to the rest of the team. Unfortunately, the other team members are reluctant to even look at StoryQ to evaluate it properly (let alone entertain the idea of applying BDD), and have convinced each other to try and remove a number of StoryQ elements from our own core testing framework, even though they originally supported the use of StoryQ, and that it doesn't impact on any other part of our testing system. Doing so would end up increasing my workload significantly overall and really goes against the grain, as I am convinced through practical experience that it is a better way to work in a test-first manner in our particular working environment, and can only lead to greater improvements in the quality of our software, given I've found it easier to stick with test first using BDD. So the question really comes down to the following: What arguments can I use to really drive the point home that it would be better to use StoryQ, or at the very least apply the BDD methodology? Can you point me to any anecdotal evidence that I can use to support my argument to adopt BDD as our standard method of choice? What counter arguments can you think of that could suggest that my wish to convert the team efforts to BDD might be in error? Yes, I'm happy to be proven wrong provided the argument is a sound one. NOTE: I am not advocating that we rewrite our tests in their entirety, but rather to simply start working in a different manner for all future testing work.

• Keeping your options open in a cloud solution

  - by BuckWoody

  In on-premises solutions we have the full range of options open for a given computing solution – but we don’t always take advantage of them, for multiple reasons. Data goes in a Relational Database Management System, files go on a share, and e-mail goes to the Exchange server. Over time, vendors (including ourselves) add in functionality to one product that allow non-standard use of the platform. For example, SQL Server (and Oracle, and others) allow large binary storage in or through the system – something not originally intended for an RDBMS to handle. There are certainly times when this makes sense, of course, but often these platform hammers turn every problem into a nail. It can make us “lazy” in our design – we sometimes don’t take the time to learn another architecture because the one we’ve spent so much time with can handle what we want to do. But there’s a distinct danger here. In nature, when a population shares too many of the same traits, it can cause a complete collapse if a situation exploits a weakness shared by that population. The same is true with not using the righttool for the job in a computing environment. Your company or organization depends on your knowledge as a professional to select the best mix of supportable, flexible, cost-effective technologies to solve their problems, whether you’re in an architect role or not.  So take some time today to learn something new. The way I do this is to select a given problem, and try to solve it with a technology I’m not familiar with. For instance – create a Purchase Order system in Excel, then in Hadoop or MongoDB, or even in flat-files using PowerShell as an interface. No, I’m not suggesting any of these architectures are the proper way to solve the PO problem, but taking something concrete that you know well and applying that meta-knowledge to another platform will assist you in exercising the “little grey cells” and help you and your organization understand what is open to you. And of course you can do all of this on-premises – but my recommendation is to check out a cloud platform (my suggestion would of course be Windows Azure :) ) and try it there. Most providers (including Microsoft) provide free time to do that.

• Is is possible to get a patch included in the current release? If so, how?

  - by Oli

  So a while back I reported a bug in Compiz's Place Window plugin. It's a fairly major regression for people affected by it: mainly those using Gnome-Fallback, judging by the reports. A patch surfaced a short time later. I created a PPA for testing and everybody involved so far is reporting the issues are fixed. It even fixes another bug. I've done testing with a standard Unity desktop and can say (for my testing) no adverse effects were visible. I want to get this pushed to Ubuntu right now for two main reasons: I'm selfish. I don't want to need to update my PPA every time a new version of Compiz is pushed to 12.04. I don't want Ubuntu users seeing their windows flying around because of a silly little bug. I want this patch pushed to Ubuntu's version of Compiz as soon as possible, so we can mark these bugs fixed and move on with our lives. Whose leg do I have to hump to get this pulled into Ubuntu right now? I don't maintain this project and it's an upstream thing but it's fairly integral to Ubuntu. I could go to Compiz but I imagine that if they accept the patch, it'll be months (at least a release) before it's anywhere near Ubuntu. And when I do find the right person, how can I make the process as slick as possible for them? I want them to see my request, go "Yup, that all looks great, done" and that be it. I don't want seventeen rounds of emails addressing aspects of the patch. More importantly, I don't want to waste their time either. And what do I have to provide them? My packaging skills are... lamentable. This was my first attempt at patching a package for redistribution so I've probably made every single packaging error known to man. Will they be happy with the original patch (so they can apply it themselves) or should I repackage things so the diff/changelog is a little cleaner (it took me a few goes and the versioning is all over the place). Note: This question is about Compiz but I'd prefer if answers could address other styles of package too so we have an authoritative and comprehensive thread of how to get things fixed.

• Travelling at Magenic

  - by Chris G. Williams

  I occasionally get asked if we travel "a lot" at Magenic. Sometimes the question comes from job candidates. Other times it's clients, recruiters or friends. To give a simple yes or no answer would be a disservice to the person asking the question. So here is my standard answer:It depends.(That was the short version.  Here's the long version...)We do have some guys that are more "national" in focus, and they can travel a fair amount. They also receive a little extra in compensation for doing so. It's a balancing act, and not necessarily a one-size-fits-all situation. Not everyone is well suited to constant travel. Some folks enjoy it and some folks hate it.With our local guys, our general policy is to TRY and keep them close to home whenever possible, but sometimes the needs of the client will dictate otherwise. (As Spock would say... the needs of the many outweigh the needs of the few, or the one.)In most cases though, we really do try to avoid sending our guys on extended travel gigs (i.e. every week for 6 months) when a simple kickoff trip and occasional visit will do. This depends on the nature of the gig, of course. Some types of work lend themselves to this model better than others. Additionally, this can and does vary by office. If one office is having trouble staffing a gig (not enough available bodies) and another office has a few too many folks on the bench, well... you can connect the dots. But again, we try to keep that to a minimum.Lastly, we all have our own thresholds for what we consider "a lot" of travel. There are two parts to this threshold:Half of it is whatever you're accustomed to already. The other half is being honest with yourself about how much you [like/hate] dealing with airports, car rentals, taxis, hotels, disruptions to your workout schedule, time away from friends/family, etc.Knowing a bit about yourself will definitely help you decide how much travel is too much for you.

• Analysing SQLBits Feedback

  - by jamiet

  Earlier this week I received all the feedback that people offered on my session at SQLBits 7 in York – “SSIS Dataflow Performance Tuning” (the video is available online if you wish to see it). As you may have gathered from previous posts on this blog and my less-SQLy-focused Wordpress blog I am a big fan of collecting and tracking both personal and public data and session feedback lends itself very well to tracking because it is quantitative rather than qualitative; by that I mean attendees are invited to provide marks out of ten rather than (or, in the case of SQLBits, as well as) written comments. The SQLBits feedback is also useful because they use a consistent format – the same questions are asked each time – this means it is particularly easy to to track whether the scores that people give are trending up or down. I suspect that somewhere the SQLBits organisers have a big Analysis Services cube (ok, perhaps its an Excel pivot table) that allows them to analyse these scores per conference, speaker, track etc.… and there’s no reason that we as session speakers cannot do the same thing. To that end I have started to store my feedback in an Excel spreadsheet of my own which in the interests of transparency is available for public viewing (only a web browser required) on SkyDrive at http://cid-550f681dad532637.office.live.com/view.aspx/Public/Misc/Personal%20SQLBits%20Session%20Feedback.xlsx. I have used a pivot table to aggregate all that feedback and here is a screenshot: I am hereby making a public plea to the SQLBits organisers (on the off-chance that they are reading) to please continue to keep the feedback format consistent in the future and I encourage them to publish all of the feedback in an anonymised form. I would also encourage anyone doing conference speaking to track their conference feedback in the same way that I am doing so that you get an insight into whether or not you are improving over time. It is not difficult to setup and maintaining it as you do more sessions takes very little effort. Storing feedback data like this leads me to wider thoughts about well-known conventions and data format standardisation. Let’s imagine a utopia where there were a standard set of questions for capturing session feedback that were leveraged at every conference regardless of subject matter, location or culture; that would give rise to immense cross-conference and cross-discipline analysis – the data analyst in me goes giddy at the thought of it. It is scenarios like this that drive my interest both in data formats such as iCalendar, microformats and RDF, and in emerging movements such as the semantic web and linked data, all things which I have written about in the past. I don’t know whether we will ever reach the stage where every piece of data has structured, descriptive metadata associated with it but I live in hope. @Jamiet

• My Doors - Why Standards Matter to Business

  - by [email protected]

  By Brian Dayton on April 8, 2010 9:27 PM "Standards save money." "Standards accelerate projects." "Standards make better solutions." What do these statements mean to you? You buy technology solutions like Oracle Applications but you're a business person--trying to close the quarter, get performance reviews processed, negotiate a new sourcing contract, etc. When "standards" come up in presentations and discussions do you: - Nod your head politely - Tune out and check your smart phone - Turn to your IT counterpart and say "Bob's all over this standards thing, right Bob?" Here's why standards matter. My wife wants new external doors downstairs, ones that would get more light into the rooms. Am I OK with that? "Uhh, sure...it's a little dark in the kitchen." - 24 hours ago - wife calls to tell me that she's going to the hardware store and may look at doors - 20 hours ago - wife pulls into driveway, informs me that two doors are in the back of her station wagon, ready for me to carry - 19 hours ago - I re-discovered the fact that it's not fun to carry a solid wood door by myself - 5 hours ago - Local handyman, who was at our house anyway, tells me that the doors we bought will likely cost 2-3x the material cost in installation time and labor...the doors are standard but our doorways aren't We could have done more research. I could be more handy. Sure. But the fact is, my 1951 house wasn't built with me in mind. They built what worked and called it a day. The same holds true with a lot of business applications. They were designed and architected for one-time use with one use-case in mind. Today's business climate is different. If you're going to use your processes and technology to differentiate your business you should have at least a working knowledge of: - How standards can benefit your business - Your IT organization's philosophy around standards - Your vendor's track-record around standards...and watch for those who pay lip-service to standards but don't follow through The rallying cry in most IT organizations today is "learn more about the business, drop the acronyms." I'm not advocating that you go out and learn how to code in Java. But I do believe it will help your business and your decision-making process if you meet IT ½...even ¼ of the way there. Epilogue: The door project has been put on hold and yours truly has to return the doors to the hardware store tomorrow.

• Windows 8/Surface Lunch Event Summary

  - by Tim Murphy

  Today was a big day for Microsoft with two separate launch event.  The first for Windows 8 and all of it’s hardware partners.  The second was specifically to introduce the Microsoft Windows 8 Surface tablet.  Below are some of the take-aways I got from the webcasts. Windows 8 Launch The three general area that Microsoft focused on were the release of the OS itself, the public unveiling of the Windows Store and the new devices available from its hardware partners. The release of the OS focused on the fact that it will be available at mid-night tonight for both new PCs and for upgrades.  I can’t say that this interested me that much since it was already known to most people.  I think what they did show well was how easy the OS really is to use. The Windows Store is also not a new feature to those of us who have been running the pre-release versions of Windows 8 or have owned Windows Phone 7 for the past 2 years.  What was interesting is that the Windows Store launches with more apps available than any other platforms store at their respective launch.  I think this says a lot about how Microsoft focuses on the ability of developers to create software and make it available.  The of course were sure to emphasize that the Windows Store has better monetary terms for developers than its competitors. The also showed off the fact that XBox Music streaming is available for to all Windows 8 user for free.  Couple this with the Bing suite of apps that give you news, weather, sports and finance right out of the box and I think most people will find the environment a joy to use. I think the hardware demo, while quick and furious, really show where Windows shine: CHOICE!  They made a statement that over 1000 devices have been certified for Windows 8.  They showed tablets, laptops, desktops, all-in-ones and convertibles.  Since these devices have industry standard connectors they give a much wider variety of accessories and devices that you can use with them. Steve Balmer then came on stage and tried to see how many times he could use the “magical”.  He focused on how the Windows 8 OS is designed to integrate with SkyDrive, Skype and Outlook.com.  He also enforced that they think Windows 8 is the best choice for the Enterprise when it comes to protecting data and integrating across devices including Windows Phone 8. With that we were left to wait for the second event of the day. Surface Launch The second event of the day started with kids with magnets.  Ok, they were adults, but who doesn’t like playing with magnets.  Steven Sinofsky detached and reattached the Surface keyboard repeatedly, clearly enjoying himself.  It turns out that there are 4 magnets in the cover, 2 for alignment and 2 as connectors. They then went to giving us the details on the display.  The 10.6” display is optically bonded to the case and is optimized to reduce glare.  I think this came through very well in the demonstrations. The properties of the case were also a great selling point.  The VaporMg allowed them to drop the device on stage, on purpose, and continue working.  Of course they had to bring out the skate boards made from Surface devices. “It just has to feel right” was the reason they gave for many of their design decisions from the weight and size of the device to the way the kickstand and camera work together.  While this gave you the feeling that the whole process was trial and error you could tell that a lot of science went into the specs.  This included making sure that the magnets were strong enough to hold the cover on and still have a 3 year old remove the cover without effort. I am glad that they also decided the a USB port would be part of the spec since it give so many options.  They made the point that this allows Surface to leverage over 420 million existing devices.  That works for me. The last feature that I really thought was important was the microSD port.  Begin stuck with the onboard memory has been an aggravation of mine with many of the devices in the market today. I think they did job of really getting the audience to understand why you want this platform and this particular device.  Using personal examples like creating a video of a birthday party and being in it or the fact that the device was being used to live blog the event and control the lights and presentation.  They showed very well that it was not only fun but very capable of getting real work done.  Handing out tablets to the crowd didn’t hurt either.  In the end I really wanted a Surface even though I really have no need for one on a daily basis.  Great job Microsoft! del.icio.us Tags: Windows 8,Win8,Windows 8 Luanch

• WCF Routing Service Filter Generator

  - by Michael Stephenson

  Recently I've been working with the WCF routing service and in our case we were simply routing based on the SOAP Action. This is a pretty good approach for a standard redirection of the message when all messages matching a SOAP Action will go to the same endpoint. Using the SOAP Action also lets you be specific about which methods you expose via the router. One of the things which was a pain was the number of routing rules I needed to create because we were routing for a lot of different methods. I could have explored the option of using a regular expression to match the message to its routing but I wanted to be very specific about what's routed and not risk exposing methods I shouldn't via the router. I decided to put together a little spreadsheet so that I can generate part of the configuration I would need to put in the configuration file rather than have to type this by hand. To show how this works download the spreadsheet from the following url: https://s3.amazonaws.com/CSCBlogSamples/WCF+Routing+Generator.xlsx In the spreadsheet you will see that the squares in green are the ones which you need to amend. In the below picture you can see that you specify a prefix and suffix for the filter name. The core namespace from the web service your generating routing rules for and the WCF endpoint name which you want to route to. In column A you will see the green cells where you add the list of method names which you want to include routing rules for. The spreadsheet will workout what the full SOAP Action would be then the name you will use for that filter in your WCF Routing filters. In column D the spreadsheet will have generated the XML snippet which you can add to the routing filters section in your configuration file. In column E the spreadsheet will have created the XML snippet which you can add to the routing table to send messages matching each filter to the appropriate WCF client endpoint to forward the message to the required destination. Hopefully you can see that with this spreadsheet it would be very easy to produce accurate XML for the WCF Routing configuration if you had a large number of routing rules. If you had additional methods in other services you can simply copy the worksheet and add multiple copies to the Excel workbook. One worksheet per service would work well.

• Is there a usage count for packages or programs?

  - by math

  Motivation: I want to remove applications I do not use to speed up my package processing tasks like dist upgrades, regular updates, but also for saving disk space and other reasons. I know this is a complex topic so first I will ask my question and second I will give some answers I already found out. Question: How do I find out which package I did not used at all? For example I always use the VLC so I could remove totem package. (Which I could have been used some day, yes.) Of course package dependencies could force me to have programs installed which I will never use. Notes: Find the packages which consume much space via synaptic: Select "Status" in lower left, select "Installed" in upper left, sort column on "size" in upper right. Then you can decide which big packages you really need. Use aptitude autoremove Use ubuntu-tweak's Janitor for removing old kernel packages, old configs, apt-cache entries, etc. Manually search for applications for a given task that you usually solve with your standard app. E.g. Movie player, Music player, Office program, Browser etc. (BTW: this is what I want to be helped with my question) When removing packages I always favour "apt-get purge" over "aptitude remove --purge" as aptitude often will also remove essential packages due to package dependencies. E.g. when removing "evolution" (as I use thunderbird) aptitude wants to remove also "ubuntu-desktop" and 756 other packages as well, while apt-get just removes evolution and its helping pacakges like evolution-common. Ubuntu lense gives me most recent used applications which are candidates for keeping :) Employ deborphan as I read in this related answer: How do I clean up my harddrive? I should certainly keep essential packages: Keep only essential packages This question is pretty much a duplicate of How to see what installed packages I have never used for cleaning purposes but covering only few aspects. However one answer suggests to use a program called unusedpkg but the link seems down. There is also a program called Kleen http://code.google.com/p/kleen/ but it won't compile in 11.10. However I hacked it to compile but the results are unusable, as for example the g++ package was marked as not used for 203, but actually I used it seconds ago for compiling Kleen itself ;) So don't use this tool. On http://wiki.debian.org/DebianPackageInformation I read the the package popularity-contest will produce log files with usage statistics. Unfortunately I didn't enabled the popularity contest so I can't find this log file.

• Solaris 11

  - by user9154181

  Oracle has a strict policy about not discussing product features until they appear in shipping product. Now that Solaris 11 is publically available, it is time to catch up. I will be shortly posting articles on a variety of new developments in the Solaris linkers and related bits: 64-bit Archives After 40+ years of Unix, the archive file format has run out of room. The ar and link-editor (ld) commands have been enhanced to allow archives to grow past their previous 32-bit limits. Guidance The link-editor is now willing and able to tell you how to alter your link lines in order to build better objects. Stub Objects This is one of the bigger projects I've undertaken since joining the Solaris group. Stub objects are shared objects, built entirely from mapfiles, that supply the same linking interface as the real object, while containing no code or data. You can link to them, but cannot use them at runtime. It was pretty simple to add this ability to the link-editor, but the changes to the OSnet in order to apply them to building Solaris were massive. I discuss how we came to invent stub objects, how we apply them to build the OSnet in a more parallel and scalable manner, and about the follow on opportunities that have emerged from the new stub proto area we created to hold them. The elffile Utility A new standard Solaris utility, elffile is a variant of the file utility, focused exclusively on linker related files. elffile is of particular value for examining archives, as it allows you to find out what is inside them without having to first extract the archive members into temporary files. This release has been a long time coming. I joined the Solaris group in late 2005, and this will be my first FCS. From a user perspective, Solaris 11 is probably the biggest change to Solaris since Solaris 2.0. Solaris 11 polishes the ground breaking features from Solaris 10 (DTrace, FMA, ZFS, Zones), and uses them to add a powerful new packaging system, numerous other enhacements and features, along with a huge modernization effort. I'm excited to see it go out into the world. I hope you enjoy using it as much as we did creating it. Software is never done. On to the next one...

• Summary of our Recent Pull Request Enhancements on CodePlex

  Over the past several weeks, we’ve been incrementally rolling out a bunch of enhancements around our pull request workflow for Git and Mercurial projects. Our goal is to make contributing to open source projects a simple and rewarding experience, and we’ll continue to invest in this area. Here’s a summary of the changes so far, in case you’ve missed them. As always, if you have any feedback, please let us know, whether on our ideas page or via Twitter. Support for branches You can now pick the source and destination branches for your pull request, whether you’re sending one from your fork, or using it within a project to collaborate with your other trusted contributors. A redesigned creation experience Our old pull request creation form was rather lacking. It asked for a title and comment in a small modal dialog, but that was about it. We knew we could do better, so we rethought the experience. Now, when you create a pull request, you’re taken to a new page that let’s you select the source and destination, and gives you information on the diffs and commits that you’re sending, so you can confirm that you’re sending the right set of changes. Inline code snippets in discussion If users comment on code in your pull request, we now display a preview of the snippet of relevant code inline with their comment on the discussion. Subsequent replies on that line are combined in a single thread to preserve your context. No more clicking and hunting to find where the comments are. And you can add another inline comment right from the discussion area. Comment notifications You can now elect receive an e-mail notification if a user comments on your pull request. If it’s on a line of code, we’ll display the relevant code snippet in the e-mail. Redesigned diff viewer Our old diff viewer hadn’t been touched in a while, and was in need of an update. We started with a visual facelift to use standard red/green colors for additions/deletions and remove the noisy “dots” that represented spaces and that littered the diff viewer. Based on feedback that the viewable region for diffs was too small, especially for smaller screen resolutions, we revamped the way the viewport for the code is sized, and now expand it to fill the majority of the browser height when scrolling down. The set of improvements we implemented here also apply anywhere diffs are viewed, not just for pull requests.

• If most of team can't follow the architecture, what do you do?

  - by Chris

  Hi all, I'm working on a greenfields project with two other developers. We're all contractors, and myself and one other just started working on the project while the orginal one has been doing most of the basic framework coding. In the past month, my fellow programmer and I have been just frustrated by the design descisions done by our co-worker. Here's a little background information: The application at face value appeared to be your standard n-layered web application using C# on the 3.5 framework. We have a data layer, business layer and a web interface. But as we got deeper into the project we found some very interesting things that have caused us some troubles. There is a custom data access sqlHelper type base which only accepts dictionary key/valued entries and returns only data tables. There are no entity objects, but there are some massive objects which do everything and then are tossed into session for persitance. The general idea is that the pages (.aspx) don't do anything, while the controls (.ascx) do everything. The general flow is that a client clicks on a button, which goes to a user control base which passes a process request to the 'BLL' class which goes to the page processor, which then goes to a getControlProcessor, which at last actually processes the request. The request itself is made up of a dictionary which is passing a string valued method name, stored procedure name, a control name and possibly a value. All switching of the processing is done by comparing the string values of the control names and method names. Pages are linked together via a common header control that uses a combination of javascript and tables to create a hyperlink effect. And as I found out yesterday, a simple hyperlink between one page and another does not work because of the need to have quite a bit of information in session to determine which control to display on a page. My fellow programmer and I both believe that this is a strange and uncommon approach to web application development. Both of us have been in this business for over five years and neither of us have seen this approach. My question is this, how would we approach our co-worker and voice our concerns and what should we do if he does not want to accept the criteic? We both do not want to insult the work that has been done, but feel that going forward will create a nightmare for development. Thanks for your comments.

• Keep coding the wrong way to remain consistent? [closed]

  - by bwalk2895

  Possible Duplicate: Code maintenance: keeping a bad pattern when extending new code for being consistent, or not? To keep things simple let's say I am responsible for maintaining two applications, AwesomeApp and BadApp (I am responsible for more and no that is not their actual names). AwesomeApp is a greenfield project I have been working on with other members on my team. It was coded using all the fancy buzzwords, Multilayer, SOA, SOLID, TDD, and so on. It represents the direction we want to go as a team. BadApp is a application that has been around for a long time. The architecture suffers from many sins, namely everything is tightly coupled together and it is not uncommon to get a circular dependency error from the compiler, it is almost impossible to unit test, large classes, duplicate code, and so on. We have a plan to rewrite the application following the standards established by AwesomeApp, but that won't happen for a while. I have to go into BadApp and fix a bug, but after spending months coding what I consider correctly, I really don't want do continue perpetuate bad coding practices. However, the way AwesomeApp is coded is vastly different from the way BadApp is coded. I fear implementing the "correct" way would cause confusion for other developers who have to maintain the application. Question: Is it better to keep coding the wrong way to remain consistent with the rest of the code in the application (knowing it will be replaced) or is it better to code the right way with an understanding it could cause confusion because it is so much different? To give you an example. There is a large class (1000+ lines) with several functions. One of the functions is to calculate a date based on an enumerated value. Currently the function handles all the various calculations. The function relies on no other functionality within the class. It is self contained. I want to break the function into smaller functions (at the very least) and put them into their own classes and hide those classes behind an interface (at the most) and use the factory pattern to instantiate the date classes. If I just broke it out into smaller functions within the class it would follow the existing coding standard. The extra steps are to start following some of the SOLID principles.

• Insert Or update (aka Replace or Upsert)

  - by Davide Mauri

  The topic is really not new but since it’s the second time in few days that I had to explain it different customers, I think it’s worth to make a post out of it. Many times developers would like to insert a new row in a table or, if the row already exists, update it with new data. MySQL has a specific statement for this action, called REPLACE: http://dev.mysql.com/doc/refman/5.0/en/replace.html or the INSERT …. ON DUPLICATE KEY UPDATE option: http://dev.mysql.com/doc/refman/5.0/en/insert-on-duplicate.html With SQL Server you can do the very same using a more standard way, using the MERGE statement, with the support of Row Constructors. Let’s say that you have this table: CREATE TABLE dbo.MyTargetTable (     id INT NOT NULL PRIMARY KEY IDENTITY,     alternate_key VARCHAR(50) UNIQUE,     col_1 INT,     col_2 INT,     col_3 INT,     col_4 INT,     col_5 INT ) GO INSERT [dbo].[MyTargetTable] VALUES ('GUQNH', 10, 100, 1000, 10000, 100000), ('UJAHL', 20, 200, 2000, 20000, 200000), ('YKXVW', 30, 300, 3000, 30000, 300000), ('SXMOJ', 40, 400, 4000, 40000, 400000), ('JTPGM', 50, 500, 5000, 50000, 500000), ('ZITKS', 60, 600, 6000, 60000, 600000), ('GGEYD', 70, 700, 7000, 70000, 700000), ('UFXMS', 80, 800, 8000, 80000, 800000), ('BNGGP', 90, 900, 9000, 90000, 900000), ('AMUKO', 100, 1000, 10000, 100000, 1000000) GO If you want to insert or update a row, you can just do that: MERGE INTO     dbo.MyTargetTable T USING     (SELECT * FROM (VALUES ('ZITKS', 61, 601, 6001, 60001, 600001)) Dummy(alternate_key, col_1, col_2, col_3, col_4, col_5)) S ON     T.alternate_key = S.alternate_key WHEN     NOT MATCHED THEN     INSERT VALUES (alternate_key, col_1, col_2, col_3, col_4, col_5) WHEN     MATCHED AND T.col_1 != S.col_1 THEN     UPDATE SET         T.col_1 = S.col_1,         T.col_2 = S.col_2,         T.col_3 = S.col_3,         T.col_4 = S.col_4,         T.col_5 = S.col_5 ; If you want to insert/update more than one row at once, you can super-charge the idea using Table-Value Parameters, that you can just send from your .NET application. Easy, powerful and effective

• Are they asking too much of me?

  - by Tesserex

  Or am I just whining? Background: I work for a "startup," which I put in air quotes because the company has been around for 4 years. We have about 40 employees in three offices, 9 here plus some part time. We have a good amount of investment and bring in about 75% of what we spend (so not profitable just yet.) Standard work week is supposed to be about 60 hours, but they justify that as we have to be online when our international (Taiwan and Vietnam) offices are awake. When I started the job 6 months ago, I spent about a month prototyping an iphone app and did really well on my own. They also found out about my facebook applications and how many users they got. Putting 2 and 2 together (and winding up at -7) they realized 1. I'm independent and innovative (because I was able to use stackoverflow to answer my iOS questions instead of bugging my superiors) and 2. I must have an eye for marketing (since my fb apps grew totally organically without me doing any advertising), and assigned me to a project optimizing adwords campaigns. Today I got reviewed, and then chewed out, by our CEO for not totally rocking this project. Now I thought I was doing ok, but the CEO said the project is stagnant and they're expecting more from me. But since it's a startup, they play loose with job roles and I've had plenty of other things to do in the past three months. Every time I ask what's most important, I get conflicting responses depending who I ask, and the end result is that almost everything has equal priority - high. I could go on about how I don't think adwords is worthwhile for us since our profit margin is so slim, and how we should be trying to improve our website first, but that's not the point. I also have explained to the office director (who originally assigned me the project, not the CEO) that I don't actually know anything about marketing, I'm just a decent programmer, but they think my general smarts will prove capable of tackling this challenge. The CEO also clarified that he wants a more technical and algorithmic approach to the problem. So is there something I can do to address this? Combined with my existing and confusing workload, should I be raising an issue? Or should I do the grown up thing and give it my all, asking for help when I need it and hoping for the best? Sorry if this is very rant-ish.

• "ODM" - One of the Support team's most valued acronyms

  - by graham.mckendry(at)oracle.com

  If you submit technical service requests (SRs) through the My Oracle Support portal, you may often see the term "ODM" used in updates from our Support team. ODM is an acronym for "Oracle Diagnostic Methodology", which defines a standard problem solving approach that all of Oracle Support uses for every technical SR. ODM provides a number of benefits to the SRs - both for the Support organization and for the customer - including a consistent approach, higher quality, justified solutions, and ultimately faster resolution. Screenshot: Example of an ODM "Issue Clarification" activity in a service request The Oracle Diagnostic Methodology applies to both categories of technical SRs: Consultative (question-answer topics) and Problem-Solution. There are a few KM Notes that describe the steps of ODM, however to keep things simple (and since those KM Notes appear to be a bit outdated), I'll summarize the ODM stages here as follows: Consultative ODM - Three mandatory stages: ODM Question: Clarification of the customer's exact question. ODM Answer: Thorough answer to the customer's question. ODM Knowledge Content: Reference to new or existing knowledge base content, or explanation why the particular SR does not necessarily require knowledge content. Problem-Solution ODM - Eight mandatory stages: ODM Issue Clarification: Clarification of the reported issue, including the symptoms, the steps to reproduce, and an outline of the business impact ODM Issue Verification: Confirmation of the issue being verified based on proof provided by the customer, such as screenshots, log files, or reproducing the issue during an Oracle Web Conference. ODM Cause Determination: Succinct outline of the root cause of the issue. ODM Cause Justification: Explanation as to why the root cause applies to this particular situation. ODM Proposed Solution(s): Succinct outline of the potential solution(s) to resolve the issue. ODM Proposed Solution(s) Justification: Explanation of why the proposed solution(s) will in fact resolve the issue. ODM Solution Action Plan: Detailed numbered instructions on how to execute the proposed solutions. ODM Knowledge Content: Reference to new or existing knowledge base content, or explanation why the particular SR does not necessarily require knowledge content. During these stages, you may see other optional ODM-related activities such as "ODM Data Collection", "ODM Action Plan", "ODM Research", and "ODM Test Case". Again, these structured tags help ensure a uniform methodology across your SRs. With this knowledge you should be able to develop better predictability of what's coming next in your SRs, as well as what you can do to help expedite the resolution process.

• How is fundamental mathematics efficiently evaluated by programming languages?

  - by Korvin Szanto

  As I get more and more involved with the theory behind programming, I find myself fascinated and dumbfounded by seemingly simple things.. I realize that my understanding of the majority of fundamental processes is justified through circular logic Q: How does this work? A: Because it does! I hate this realization! I love knowledge, and on top of that I love learning, which leads me to my question (albeit it's a broad one). Question: How are fundamental mathematical operators assessed with programming languages? How have current methods been improved? Example var = 5 * 5; My interpretation: $num1 = 5; $num2 = 5; $num3 = 0; while ($num2 > 0) { $num3 = $num3 + $num1; $num2 = $num2 - 1; } echo $num3; This seems to be highly inefficient. With Higher factors, this method is very slow while the standard built in method is instantanious. How would you simulate multiplication without iterating addition? var = 5 / 5; How is this even done? I can't think of a way to literally split it 5 into 5 equal parts. var = 5 ^ 5; Iterations of iterations of addition? My interpretation: $base = 5; $mod = 5; $num1 = $base; while ($mod > 1) { $num2 = 5; $num3 = 0; while ($num2 > 0) { $num3 = $num3 + $num1; $num2 = $num2 - 1; } $num1 = $num3; $mod -=1; } echo $num3; Again, this is EXTREMELY inefficient, yet I can't think of another way to do this. This same question extends to all mathematical related functions that are handled automagically.

• Complete Beginner to Game Programming and Unreal Engine 4, Looking For Advice [on hold]

  - by onemic

  I am currently a 2nd year programming student(Just finished my first year so I will be starting my second year in September) and have mainly learned C and C++ in my classes. In terms of what I know of C++, I know about general inheritance, polymorphism, overloading operators, iterators, a little bit about templates(only class and function templates) etc. but not of the more advanced topics like linked lists and other sequential containers(containers in general I guess), enumerations, most of the standard library(other than like strings and vectors), and probably a bunch of other stuff I dont even know about yet. I subscribed to Unreal Engine 4 as I was very intrigued by their Unreal Tournament announcement earlier this month, especially after hearing that UE4 is going completely C++. Of course my end goal in doing this programming program is to eventually go into game/graphics programming. Since it's my summer off, I thought what better way then to actually apply some of my skills to a personal project so I actually have a firmer understanding of C++ past what my professors tell me. My questions are this: What would be the best way to start off making a small personal game in UE4 as a project for the summer? What should I be aiming for, especially for someone that is still learning C++? Should I focus on making a simple 2D game rather than a 3D one to get started? Seeing the Flappy Chicken showcase intrigued me because before I thought the UE engine was pretty much pigeonholed into being for FPS games What should my expectations be going into UE4 and a game engine for the first time?(UE4 will be my first foray into making a game) What can I expect to gain from making things in UE4, in terms of making games and in terms of further fleshing out my knowledge of C++? Would you recommend I start off 100% using C++ for scripting or using the visual blueprints? Since I'm not a designer, how would I be able to add objects and designs to my game? For someone at my level is retaining the UE4 subscription worth it or is it better to cancel and resub when I learn enough about UE4 and C++? Lastly is there anything to be gained in terms of knowledge/insight through me looking at the source code for UE4? I opened it in VS2013, but noticed that most of the files were C# files and not cpp's. Thanks in advance for taking the time to answer.
