• What electronic user-story-mapping tools can you recommend?

  - by azheglov

  Agile software development relies heavily on a work item type called user stories. For example, you have a backlog full of user stories and you can select a few of them to work on during the next sprint. But where and how do you find user stories to put into the backlog? There is a popular technique for doing that called story mapping. Jeff Patton invented it and here is the definitive guide on how to do it. The question is, what electronic tools are out there that support Patton's story-mapping technique? I've done a bit of research, found Pivotal and Rally plug-ins (but I'm not a customer of either) and I'm currently experimenting with SilverStories. What other tools are out there? What have you used? What do you (not) recommend? Why? UPDATE: Some people who wrote comments seem to lean towards an answer that applying this technique is simply impossible with an electronic tool and we should just accept that. Can't someone write it up as an answer?

• Are there any actual case studies on rewrites of software success/failure rates?

  - by James Drinkard

  I've seen multiple posts about rewrites of applications being bad, peoples experiences about it here on Programmers, and an article I've ready by Joel Splosky on the subject, but no hard evidence of case studies. Other than the two examples Joel gave and some other posts here, what do you do with a bad codebase and how do you decide what to do with it based on real studies? For the case in point, there are two clients I know of that both have old legacy code. They keep limping along with it because as one of them found out, a rewrite was a disaster, it was expensive and didn't really work to improve the code much. That customer has some very complicated business logic as the rewriters quickly found out. In both cases, these are mission critical applications that brings in a lot of revenue for the company. The one that attempted the rewrite felt that they would hit a brick wall at some point if the legacy software didn't get upgraded at some point in the future. To me, that kind of risk warrants research and analysis to ensure a successful path. My question is have there been actual case studies that have investigated this? I wouldn't want to attempt a major rewrite without knowing some best practices, pitfalls, and successes based on actual studies. Aftermath: okay, I was wrong, I did find one article: Rewrite or Reuse. They did a study on a Cobol app that was converted to Java.

• Entry / JR Php Programmer - What do I learn next?

  - by dtj

  I got very interested in programming toward the end of college. Took a few classes, but learned most everything on my own via books and such. Its mostly been Php and MySQL. Right out of school, I got a job working at a company for 2 years (web media) and ended up learning a lot of stuff and programming some things for them. I am no longer at that company but I am looking for my next steps as a programmer. I really enjoy Web Development and Php and MySQL seems to be my thing. Basically, I know how to do CRUD operations, i am mediocre at OOP and still have more to learn, I know HTML and CSS quite well, I know my way around a Unix terminal and can access MySQL through it and set up cron jobs and such. I know some basic Javascript. Whats a good next step? I don't anything about 3rd party services, PDO, APIs (twitter, facebook, etc), Drupal / Joomla, Unit Testing, E-Commerce, PECL, PEAR ....in other words A LOT I get easily overwhelmed by the amount of stuff there is to learn, so I'm sort of trying to find a path. Right now, I'm digging into OOP more, as that seems like a good conceptual first-step. Any suggestions?

• Get entities ids from two similar collections using one method

  - by Patryk Roszczyniala

  I've got two lists: List<Integer, ZooEntity> zoos; List<Integer, List<ZooEntity>> groupOfZoos; These operations will return collections of values: Collection<ZooEntity> cz = zoos.values(); Collection<List<ZooEntity>> czList = groupOfZoos.values(); What I want to achieve is to get list of all zoo ids. List<Integer> zooIds = cz ids + czList ids; Of course I can create two methods to do what I want: public List<Integer> getIdsFromFlatList(Collection<ZooEntity> list) { List<Integer> ids = new ArrayList<Integer>(); for (ZooEntity z : list) { ids.add(z.getId()); } return ids; } public List<Integer> getIdsFromNestedList(Collection<List<ZooEntity>> list) { List<Integer> ids = new ArrayList<Integer>(); for (List<ZooEntity> zList : list) { for (ZooEntity z : zList) { ids.add(z.getId()); } } return ids; } As you can see those two methods are very similar and here is my question: Is it good to create one method (for example using generics) which will get ids from those two lists (zoos and groupOfZoos). If yes how it should look like? If no what is the best solution? BTW. This is only the example. I've got very similar problem at job and I want to do it in preety way (I can't change enities, I can change only getIds...() methods).

• Oracle Magazine: Getting started with SQL Analytics

  - by KLaker

  I am currently working on a series of podcasts covering the broad categories of our SQL analytical functions and features and while I was doing some research I came across of series of four articles in the Oracle Magazine. This series of article is written by Melanie Caffrey who is a senior development manager at Oracle. She is a coauthor of Expert PL/SQL Practices for Oracle Developers and DBAs (Apress, 2011) and Expert Oracle Practices: Oracle Database Administration from the Oak Table (Apress, 2010). The four articles are under the banner "Technology: SQL 101" and parts 9, 10, 11 and 12 cover SQL analytics. Here are the links to the four articles: Jan 2013 Having Sums, Averages, and Other Grouped Data March 2013 A Window into the World of Analytic Functions May 2013 Leading Ranks and Lagging Percentages: Analytic Functions, Continued July 2013 Pivotal Access to Your Data: Analytic Functions, Concluded The articles cover topics such as GROUP BY, SUM, AVG, HAVING, window functions, RANK, FIRST, LAST, LAG, LEAD etc.   The great news is that  you can try out the examples in this series. All you need is access to an Oracle Database instance. All the schemas, data sets and SQL statements that you will need can be downloaded from a link included in the January article.    I hope you find this series of articles useful.

• Caching strategies for entities and collections

  - by Rob West

  We currently have an application framework in which we automatically cache both entities and collections of entities at the business layer (using .NET cache). So the method GetWidget(int id) checks the cache using a key GetWidget_Id_{0} before hitting the database, and the method GetWidgetsByStatusId(int statusId) checks the cache using GetWidgets_Collections_ByStatusId_{0}. If the objects are not in the cache they are retrieved from the database and added to the cache. This approach is obviously quick for read scenarios, and as a blanket approach is quick for us to implement, but requires large numbers of cache keys to be purged when CRUD operations are carried out on entities. Obviously as additional methods are added this impacts performance and the benefits of caching diminish. I'm interested in alternative approaches to handling caching of collections. I know that NHibernate caches a list of the identifiers in the collection rather than the actual entities. Is this an approach other people have tried - what are the pros and cons? In particular I am looking for options that optimise performance and can be implemented automatically through boilerplate generated code (we have our own code generation tool). I know some people will say that caching needs to be done by hand each time to meet the needs of the specific situation but I am looking for something that will get us most of the way automatically.

• What techniques would you use for a next generation java web application?

  - by jakob

  I'm working at a site similar to Foursquare and Yelp, with approximately 100000 unique requests each week that generates content, growing steadily. We are currently using: Seam as Java web framework. MySQL as DB Hibernate as ORM Hibernate Search as Index EhCache for Caching. Since our site is slowly growing out of the current setup and has a lot of legacy code, it is time for us to start thinking about a major refactoring/changing setup. Web framework We are not ready to change the language but we are leaning towards Spring Web Framework, since: Seam is no more. Almost all of us have worked with Spring and liked it. DB and ORM We have done a little research and we are thinking about MongoDB. Index Do we need to have a separate Index if we use MongoDB? Cache ? So my question is basically: If you take Spring Web Framework and MongoDB into consideration, how would a good setup be for a web application that is growing and handles a lot of logged in users generating input and performing searches?

• Hosting WCF over internet

  - by user1876804

  I am pretty new to exposing the WCF services hosted on IIS over internet. I will be deploying a WCF service over IIS(6 or 7) and would like to expose this service over the internet. This will be hosted in a corporate network having firewall, I want this service to be accessible over the internet(should be able to pass through the firewall) I did some research on this and some of the pointers I got: 1. I could use wsHTTPBinding or nettcpbinding (the client is intended to be .net client). Which of the bindings is preferable. 2. To overcome the corporate I came across DMZ server, what is the purpose of this and do I really need to use this). 3. I will be passing some files between the client and server, and the client needs to know the progress of the processing on server and the end result. I know this is a very broad question to ask, but could anyone give me pointers where I could start on this and what approach to take for this problem.

• RTFMobile

  - by ultan o'broin

  It may seem obvious but it’s worth stating again. The idea that mobile users are going to read lots of user assistance on their devices is just wrong. So, Jakob Nielsen’s post Mobile Content Is Twice as Difficult serves as a timely reminder for anyone thinking of putting manuals as a form of user assistance onto mobile phones. There is also an excellent post on UXMag.com, explaining that one of the ways to screw up with your iPhone app is to throw an old-style user manual into the user experience: 10 Surefire Ways to Screw Up Your iPhone App.   (Image copyright and referenced from UX Magazine 2010)   Instead, user assistance  alternatives—if any at all—include one-time tours, graphics, in-context instructions, and so on. Not so sure that importing “humor” and “personality” work so well in the enterprise app space, myself. However, the message is clear: iPhone users don’t read manuals. Great message. Users will figure it out, and if they can’t, well then your app’s UX is a problem and the app will fail. Shame some teams are obsessed with figuring out ways to port existing manuals to mobile platforms without any thought for the UX. Razorfish’s Scatter/Gather blog says it all: One thing that is particularly discouraging, most material currently available on “Creating Content for the iPad” or similar themes turns out to be about getting traditional content onto, or into, the iPad. Now, manuals for non-end users in PDF format on eReaders is a different matter. I have research on that, but it’s for another post.

• Basic Connections Through Socket Server

  - by Walrus

  I'm designing a simple 2 player RTS with Stencyl, a program that uses blocks for coding. The current code updates lists whenever an actor moves (new X and Y), and I'd want the server to update the game state with each change to the list. However, to start off: I don't even know how to set up a socket server. Stencyl has taught me the basics of logic, but I've yet to learn any programming languages. I've downloaded a Smartfox 2X socket server that I'm intending to use. Right now I'm only looking to make baby steps; I want to do something to this effect: "When someone connects to the server, open insert file here". How can I do this? My intention is to have this file be the game client. Is this "open file when connected" method the best way to go about this? When answering: assume that I know nothing, because really, though I have done research (I know that UDPTCP for real time), implementation-wise I know nothing.

• "Failed to create swap space" error during installation

  - by Welsh Heron

  I've been trying to install Ubuntu for the past two days or so, but I've been running into a problem: every time I run the installation program on the LiveCD, I always get the same (or a very similar) error: "Failed to create Swap space The creation of swap space in partition #3 of SCSI5 (0,0,0)(sda) failed." So far, I've run DBAN (Darik's Boot and Nuke) on my HDD once, to make absolutely sure that everything on it had been erased. Then, I simply put in the LiveCD, and let it run the automated install. I get the above error directly after I tell it to automatically partition the HDD (it will work for a second or so, then this will pop up), forcing me back to the screen that lets me choose whether I want to automatically or manually partition the HDD. Well, after failing to install the software manually, I did a little research and learned enough about partitioning Linux to use the 'Manual partitioning' option. I partitioned the HDD as follows (it's a 1TB drive): /home - (the rest)- ext2, / - 20GB - ext2, /boot - 100MB - ext2, /swap - 8GB /EFIboot - 40MB The only difference when I tried this method was that I got THIS message: "Failed to create Swap space The creation of swap space in partition #2 of SCSI5 (0,0,0)(sda) failed." Basically, the only difference was that there was now a '2' instead of a '3'. If I may ask, what exactly am I doing wrong? I've tried looking around the internet (that's basically all I've done for the last two days), but no one seems to have the same problem that I have, and I've tried most of the solutions for similar problems (DBAN, formatting partitions in ext2 format, etc). The only thing I haven't tried is using the terminal to manually partition the HDD...and I actually DID try to do this, but I wasn't able to get past 'su' 's password demand, so I wasn't able to use the terminal. Thank you for your help in advance. ~Welsh

• Programmer + Drugs =? [closed]

  - by sytycs

  I just read this quote from Steve Jobs: "Doing LSD was one of the two or three most important things I have done in my life." Now I'm wondering: Has there ever been a study where programmers have been given drugs to see if they could produce "better" code? Is there a programming concept, which originated from people who where drug-users? Do you know of a piece of code, which was written by someone under the influence? EDIT So I did a little more research and it turns out Dennis R. Wier actually documented how he took LSD to wrap his head around a coding project: "At one point in the project I could not get an overall viewpoint for the operation of the entire system. It really was too much for my brain to keep all the subtle aspects and processing nuances clear so I could get a processing and design overview. After struggling with this problem for a few weeks, I decided to use a little acid to see if it would enable a breakthrough, because otherwise, I would not be able to complete the project and be certain of a consistent overall design"[1] There is also an interesting article on wired about Kevin Herbet, who used LSD to solve tough technical problems and chemist Kary Mullis even said "...that LSD had helped him develop the polymerase chain reaction that helps amplify specific DNA sequences."

• Why do some bad websites rank well?

  - by BradB

  Consider the following scenario: you are pitching SEO/Website Optimisation to a prospective client and you explain to them the importance of great copy and content, how acquiring links (ethically) can increase page rank, why the quality of the HTML build matters (H1, H2 tags, w3c validation etc), why keyword research is beneficial, you may drop in a few Google Webmaster Guideline or Matt Cutts references to back up your claims and rubbish the "back hat" approach as being no longer effective for good measure. Your advice is ethical and in the eyes of best practices, spot on. Then, the client points out to you some of their long established competitors on Google and you see these competitor websites ranking in the top spots (1 to 3) for medium to highly competitive search phrases that your client wants to compete for. These websites totally contradict your ethical approach and pretty much violate every best practice previously noted. They even out perform other "white hat" competitors who are in accordance with the above guidelines. I experienced this today. One of these well ranking websites had: About six microsites with more or less the same copy and a slightly varied layout Little or not textual content I would almost say duplicate content across the sites, but there was so little of it it could barely qualify for being duplicate All the content in Flash (with a music track that kicked in on each page load, not so much of an SEO issue - but it helps paint the picture) Keyword stuffing behind the Flash file with a bunch of black text on black background in the style of keyword 1 keyword 2,keyword1,keyword 2,keyword 2 keyword 3 and so on... The exact keyword stuffed combination present on every page of the website A bunch of clearly self made links from poor quality forums and directories with little or no Page Rank Links exchanged across the microsites How do you explain your way out of this when this hard evidence is sat in front of you undermining your great pitch?

• 12.04.1 no audio through HDMI

  - by JoJo

  having a bit of an issue with getting audio to go through HDMI. Here are the base specs: OS: Ubuntu Desktop 12.04.1 x64 CPU: AMD A10-5800K 3.8G 4M FM2 R Mobo: MSI FM2-A75MA-E35 OS: Ubuntu 12.04.1 LTS Vid Card: (integrated on CPU) AMD Radeon HD 7660D HDMI sound works fine under Win7 (after mobo and vid drivers are installed), so it's not physically broken. Audio through the normal headphone jacks works fine under Ubuntu. Looking at the audio panel, there is no HDMI output at all. aplay -l also reports only: card 0: Generic [HD-Audio Generic], device 0: ALC887-VD Analog [ALC887-VD Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 In additional drivers there are two versions: ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER ATI/AMD PROPRIETARY FGLRX GRAPHICS DRIVER (post-release update) The first installs, but problem persists. I do get more resolutions to pick from. Second version does not, reporting it failed installation and to find details at: /var/log/jockey.log Looked at the log, and it's insanely long, if necessary I can get it to you guys. Did more research and some had luck by manually installing the drivers, so tried to give that a shot by following this: https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6 starting at 3.1 Manually installing Catalyst 12.6. I immediately had 2 issues, (1) the AMD website does not provide any drivers for Linux, and (2) the following command did not work: sudo sh amd-driver-installer-12-6-x86.x86_64.run --buildpkg Ubuntu/precise sh: 0: Can't open amd-driver-installer-12-6-x86.x86_64.run Some other posts stated to update "alsa-drivers", but that also did not work as install command for the new version of them did not work. I forget the exact issue, but similar to above, cannot open / cannot find. Any help would be greatly appreciated!

• Where to find Hg/Git technical support?

  - by Rook

  Posting this as a kind of a favour for a former coleague, so I don't know the exact circumstances, but I'll try to provide as much info as I can ... A friend from my old place of employment (maritime research institute; half government/commercial funding) has asked me if I could find out who provides technical support (commercial) for two major DVCS's of today - Git and Mercurial. They have been using VCS for years now (Subversion while I was there, don't know what they're using now - probably the same), and now they're renewing their software licences (they have to give a plan some time in advance for everything ... then it goes "through the system") and although they will be keeping Subversion as well, they would like to justify beginning of DVCS as an alternative system (most people root for Mercurial since it seems simpler; mostly engineers and physicians there who are not that interested in checking Git repos for corruption and the finer workings of Git, but I believe any one of the two could "pass") - but it has to have a price (can be zero; no problem there) and some sort of official technical support. It is a pro forma matter, but it has to be specified. Most of the people there are using one of the two already, but this has to be specified to be official. So, I'm asking you - do you know where could one go for Git or Mercurial technical support (can be commercial)? Technical forums and the like are out of the question. It has to work on the principle: - I have a problem. - I post a question with the details. - I get an answer in specified time. It can be "we cannot do that." but it has to be an official answer and given in agreed time. I'm sure by now most of you understand what I'm asking, but if not - post a comment or similar. Also, if you think of any reasons which could decide justification of introducing Git/Hg from an technical and administrative viewpoint, feel free to write them down also.

• Advantages of Hudson and Sonar over manual process or homegrown scripts.

  - by Tom G

  My coworker and I recently got into a debate over a proposed plan at our workplace. We've more or less finished transitioning our Java codebase into one managed and built with Maven. Now, I'd like for us to integrate with Hudson and Sonar or something similar. My reasons for this are that it'll provide a 'zero-click' build step to provide testers with new experimental builds, that it will let us deploy applications to a server more easily, that tools such as Sonar will provide us with well-needed metrics on code coverage, Javadoc, package dependencies and the like. He thinks that the overhead of getting up to speed with two new frameworks is unacceptable, and that we should simply double down on documentation and create our own scripts for deployment. Since we plan on some aggressive rewrites to pay down the technical debt previous developers incurred (gratuitous use of Java's Serializable interface as a file storage mechanism that has predictably bit us in the ass) he argues that we can document as we go, and that we'll end up changing a large swath of code in the process anyways. I contend that having accurate metrics that Sonar (or fill in your favorite similar tool) provide gives us a good place to start for any refactoring efforts, not to mention general maintenance -- after all, knowing which classes are the most poorly documented, even if it's just a starting point, is better than seat-of-the-pants guessing. Am I wrong, and trying to introduce more overhead than we really need? Some more background: an alumni of our company is working at a Navy research lab now and suggested these two tools in particular as one they've had great success with using. My coworker and I have also had our share of friendly disagreements before -- he's more of the "CLI for all, compiles Gentoo in his spare time and uses Git" and I'm more of a "Give me an intuitive GUI, plays with XNA and is fine with SVN" type, so there's definitely some element of culture clash here.

• How do I speed up XML parsing operation?

  - by absentx

  I currently have a php script set up to do some xml parsing. Sometimes the script is set as an on page include and other times it is accessed via an ajax call. The problem is the load time for this particular page is very long. I started to think that the php I had written to find what I need in the XML was written poorly and my script is very resource intense. After much research and testing the problem is indeed not my scripting (well perhaps you could consider it a problem with my scripting), but it looks like it takes a long time to load the particular xml sources. My code is like such: $source_recent = 'my xml feed'; $source_additional = 'the other feed I need'; $xmlstr_recent = file_get_contents($source_recent); $feed_recent = new SimpleXMLElement($xmlstr_recent); $xmlstr_additional = file_get_contents($source_additional); $feed_additional = new SimpleXMLElement($xmlstr_additional); In all my testing, the above code is what takes the time, not the additional processing I do below. Is there anyway around this or am I at the mercy of the load time of the xml URL's? One crazy thought I had to get around it is to load the xml contents into a db every so often, then just query the db for what I need. Thoughts? Ideas?

• responsibility for storage

  - by Stefano Borini

  A colleague and I were brainstorming about where to put the responsibility of an object to store itself on the disk in our own file format. There are basically two choices: object.store(file) fileformatWriter.store(object) The first one gives the responsibility of serialization on the disk to the object itself. This is similar to the approach used by python pickle. The second groups the representation responsibility on a file format writer object. The data object is just a plain data container (eventually with additional methods not relevant for storage). We agreed on the second methodology, because it centralizes the writing logic from generic data. We also have cases of objects implementing complex logic that need to store info while the logic is in progress. For these cases, the fileformatwriter object can be passed and used as a delegate, calling storage operations on it. With the first pattern, the complex logic object would instead accept the raw file, and implement the writing logic itself. The first method, however, has the advantage that the object knows how to write and read itself from any file containing it, which may also be convenient. I would like to hear your opinion before starting a rather complex refactoring.

• Oracle in Romania - 1: Brand new office, "Greenest in Bucharest"

  - by Steve Walker

  The importance of Romania within Oracle's global operations was underlined the other day as a marvellous new office building was opened at Floreasca Park in Bucharest.  The importance of the new facility was further underlined by presence of Oracle President Safra Catz, who participated in the opening ceremony. Seen here opening the building alongside Oracle Romania country leader Sorin Mindrutescu, Safra Catz said, "Our presence in Bucharest is significant and the work our teams are doing here is hugely valuable to our company and to our customers and partners. Our expansion in Bucharest signals our success in the region and commitment to making a positive contribution to the Romanian economy." The office itself looks very impressive, as the photos above show.  But more importantly, it is a cutting edge "green" office building in Bucharest, offering modern, environmentally friendly solutions such as a geo-thermal pump for heating and cooling, eco-friendly and chemical free materials used in walls and floors, a complex shading system, a bio diversity garden, and water and electricity saving equipment throughout the building. Floreasca Park is styled "the greenest office building in Bucharest" and its environmental credentials are laid out in full in a comprehensive infographic. Finally, Oracle's commitment to its Romanian operation was recognised as the company is proud to have been voted the most desired employer in Romania in surveys conducted by Catalyst Solutions and Brainspotting Consultancy. So, here's to the success of the Romanian operation, an important part of Oracle's global business and further testament to the importance of EMEA's contribution to the company's success.

• My Big Break - this is my story and I am sticking to it ;)

  - by dbasnett

  The value of undertaking new and difficult tasks can have many wonderful consequences, don't you agree? Here is the story of my big break. Remember yours? During the mid 70's I was in the Navy and worked as a computer operator at the CNO's Command and Control computer system (WWMCCS) in the Washington Navy Yard. I was a tape ape, but knew that I wanted to be a systems programmer. One day the Lieutenant in charge of the OS group was running a test that required the development system to be re-booted, and I was politely hinting that I wanted out of computer operations. As he watched the accounting tape rewind to BOT and then search for where it had just been (severalminutes) he told me if I would fix "that" he would have me transferred. I couldn't say "Deal" fast enough. Up until then my programming experience had been on Edsger Dijkstra's favorite computer (sic), an IBM 1620. It took almost 6 months of learning the assembler for the Honeywell 6000 and finding the code responsible for rewinding the tape and then forwarding it. After much trial and error at o’dark thirty I succeeded. The tape barely moved and my “patch” was later adopted by many other sites. Lieutenant Jack Cowan kept his promise and I have gone on to have a varied and enjoyable career. To Jack, and the rest of the crew (Ken, Stu, Neil, Tom, Silent W, Mr. Jacobs, Roy, Rocco, etc.) I’d like to thank you all.

• Has anyone else read "Programming video games for the Evil Genius"

  - by Martin

  I bought this book called "Programming Video Games for the Evil Genius" by Ian Cinnamon. If there is anyone who has read or is familiar with this book I am wondering if they think it is worth reading. I am interested in making video games. I have already taken intro courses in C++, Java and Python and got through okay. I've been going through this book for about a month now(SLOWLY). All I have to do is type the code exactly in the book, BUT a lot of the code is not clearly explained. I do some research online but I usually still have some trouble answering my questions. Then I found stack overflow. It's been a ton of help. Right now I am trying to make a racing game right out of this book and I got to a point where the author left a bunch of errors in his code. One of the members of this website fixed it up for me, but added some stuff that I'm having trouble understanding. I spend more time trying to figure out the authors errors and fix them or get someone to help me fix them than I actually do learning code. I REALLY want to learn how to do this and I am ready and willing to put in the time, but I'm not sure if my time would be better spent learning from a different source. Are there any veterans out there that are familiar with this book and think it's worth it/not worth it? Should I try to move onto another book? Any advice for a fresh start for someone who wants to learn some video game programming?

• Booting sequence. Ubuntu 12.04 installation and cohabitation with former OSes

  - by Stephane Rolland

  I am on the brink of installing Ubuntu 12.04 Precise Pengolin on the first primary partition of my hard-drive. (A day in History for me since I had always kept a MS windows at this first place). But I have some fears: This is my last computer available (In the past I used to have 2 or even 3 machines so I could always un/plug HDs for recovery operations and rescue) The current booting sequence is not straight forard. So as to explain the boot sequence let me briefly sum-up the history of this laptop computer. It was a dedicated Windows Vista computer. 1st and only Primary partition. Then I added Windows 7 (on the 2nd primary partition) letting the Windows Vista Boot Loader manage the boot sequence. Then I added Ubuntu 10.04 Lucid Lynx on the 1st sub-partition of the Extended Partitionm asking Grub to be the boot loader. But when I ask Grub to launch windows it launches the Vista BootLoader that manages the choice betzeen Vista and 7. So in theory Grub is on the MasterBootRecord - though I understand where the Vista BootLoader remains. Now, I will no longer use the Ubuntu 10.04 ( on extended partition) and also the Windows vista (on the first primary partition). I will install Ubuntu 12.04 on the First Primary, asking it to install a new bootloader. I want to keep the Windows 7 that is already on the Second Primary partition. And I want it to be loaded by the Ubuntu Boot loader(I don4t knoz zhich is included in this version)... And I am afraid the last point will not work.

• OT: Fixing choppy video playback on OS X

  - by terrencebarr

  This is a bit off-topic but I wanted to share because it seems a lot of people are running into issues with choppy video playback and stutter on Mac OS X. I am using a Mac Mini with Snow Leopard (10.6.8) as a home media center and it has worked great in the past, playing back music and videos from multiple sources (web, quicktime, VLC, EyeTV). A few weeks ago the video playback from all my sources started to become choppy, to stutter, and often the picture would hang for seconds at a time. Totally unusable. Drove me nuts for two weeks. After much research and trial-and-error it turns out the problem was an outdated Flash Player which seems to have messed up the video pipeline for the entire system. The short is, I updated the Flash Player to version 11 directly from the Adobe web site, rebooted the Mac Mini, and all is well again! Judging from the various posts across the web, video playback appears to be a fairly widespread problem for Mac users and I hope this helps some of you out there! And I can’t wait to get rid of Flash altogether – I can’t remember the times it has crashed my browser, hung my system, and screwed up things. Thanks Adobe ;-( Cheers, – Terrence Filed under: Uncategorized Tagged: Adobe Flash, Mac OS X
