  • Ubuntu suddenly won't boot on a Mac

    - by emchristiansen
    I installed 11.10 in dual-boot mode following instructions here: https://help.ubuntu.com/community/MactelSupportTeam/AppleIntelInstallation Everything worked fine, until I recently updated from Mac OS 10.6.x to the latest 10.6.x (this was a minor update prompted by OS X). The update made the rEFIt screen disappear, so I ran Boot Repair and reinstalled rEFIt and everything worked. I accidentally left my computer without power while booted into Ubuntu, until it presumably died or hibernated itself. I have been unable to boot into Ubuntu since. I didn't see the GRUB screen when I selected Linux the rEFIt chooser. Then I reinstalled rEFIt and the Linux option disappeared from the rEFIt chooser. This is a link to the boot info collected by Boot Repair: http://paste.ubuntu.com/755543/ Any help would be appreciated, especially an explanation of what all these components are (EFI, MBR, GPT, GRUB), where they live on disk, how the system knows to find each component, and how they relate to each other. Thanks!

  • Morgan Stanley chooses Solaris 11 to run cloud file services

    - by Frederic Pariente
    At the EAKC2012 Conference last week in Edinburg, Robert Milkowski, Unix engineer at Morgan Stanley, presented on deploying OpenAFS on Solaris 11. It makes a great proofpoint on how ZFS and DTrace gives a definite advantage to Solaris over Linux to run AFS distributed file system services, the "cloud file system" as it calls it in his blog. Mike used ZFS to achieve a 2-3x compression ratio on data and greatly lower the TCA and TCO of the storage subsystem, and DTrace to root-cause scalability bottlenecks and improve performance. As future ideas, Mike is looking at leveraging more Solaris features like Zones, ZFS Dedup, SSD for ZFS, etc.

  • What is the best solution for document archiving?

    - by Anders Wallenquist
    I'm looking for a utility that helps me (and my colleagues) to archive documents in a systematic manner (Like Zeitgeist but permanent). The utility have to clean-out old document from desktops and store them on a server (as automatic as possible and consistent) maybe from just a few locations (Document directory) Documents shall be stored on cheap large media for many years to come - hard disk and file system maybe? Easy to maintain and manage for a small organization. Documents have to be easy to find and restore One systematic manner could be a directory-structure by year, month, user or user, year, month. Its a plus if documents could be linked to a project, if documents could be search-able and if document could also be mail, IM-discussions not only OpenOffice traditional documents. Any ideas?

  • Workflows in SharePoint 2013, Part 1

    - by Sahil Malik
    SharePoint 2010 Training: more information Hooray! My latest article is now online on code-magazine. And this time, it’s about “Workflows in SharePoint 2013” – and there will be a part 2 of this next month. Here is a starter .. If we have been friends for a while, you must know my opinions about workflows in SharePoint 2010 and SharePoint 2007. I didn’t think they were very good, especially from a performance and scalability point of view. Frankly I think Microsoft should have called them “workslows.” Though, I don’t think it was the implementation in SharePoint that was the issue, it was fundamental issues with Workflow Foundation, compounded by the nature of SharePoint that acerbated the issues. Well, I am happy to say that Workflows in SharePoint 2013 are something I feel quite comfortable recommending to anyone, and I hope to make that case in this article. Read more ..

  • Is windows a "second class citizen" in the django community?

    - by Daniel Upton
    I'm currently doing R&D for a web application which we plan to host ourselves initially and then allow customers to self host. My task has been evaluating web frameworks to see which would give us the biggest productivity initially and ease of maintence while also allowing us to easily support deployment to customer controlled environments. Our team has experience with ASP.NET (MVC and Webforms) and Ruby on Rails. Our experience with rails is that windows deployment is a very taboo subject and any questions on IRC or SO are met with knee jerk "why not linux" responses.. However in this case our target market may be running windows or linux servers. Is this also the case in django land? Is it possible with rubbish performance? Is it possible with lost of pain? Is it seen as reasonable and not treated as a completely stupid idea for not wanting to run linux?

  • How to Encrypt Your Home Folder After Installing Ubuntu

    - by Chris Hoffman
    Ubuntu offers to encrypt your home folder during installation. If you decline the encryption and change your mind later, you don’t have to reinstall Ubuntu. You can activate the encryption with a few terminal commands. Ubuntu uses eCryptfs for encryption. When you log in, your home directory is automatically decrypted with your password. While there is a performance penalty to encryption, it can keep private data confidential, particularly on laptops that may be stolen. HTG Explains: What Is RSS and How Can I Benefit From Using It?

  • Interview with Ronald Bradford about MySQL Connect

    - by Keith Larson
    Ronald Bradford,  an Oracle ACE Director has been busy working with  database consulting, book writing (EffectiveMySQL) while traveling and speaking around the world in support of MySQL. I was able to take some of his time to get an interview on this thoughts about theMySQL Connect conference. Keith Larson: What where your thoughts when you heard that Oracle was going to provide the community the MySQL Conference ?Ronald Bradford: Oracle has already been providing various different local community events including OTN Tech Days and  MySQL community days. These are great for local regions both in the US and abroad.  In previous years there has been an increase of content at Oracle Open World, however that benefits the Oracle community far more then the MySQL community.  It is good to see that Oracle is realizing the benefit in providing a large scale dedicated event for the MySQL community that includes speakers from the MySQL development teams, invested companies in the ecosystem and other community evangelists.I fully expect a successful event and look forward to hopefully seeing MySQL Connect at the upcoming Brazil and Japan OOW conferences and perhaps an event on the East Coast.Keith Larson: Since you are part of the content committee, what did you think of the submissions that were received during call for papers?Ronald Bradford: There was a large number of quality submissions to the number of available presentation sessions. As with the previous years as a committee member for the annual MySQL conference, there is always a large variety of common cornerstone MySQL features as well as new products and upcoming companies sharing their MySQL experiences. All of the usual major players in the ecosystem will in presenting at MySQL Connect including Facebook, Twitter, Yahoo, Continuent, Percona, Tokutek, Sphinx and Amazon to name a few.  This is ensuring the event will have a large number of quality speakers and a difficult time in choosing what to attend. Keith Larson: What sessions do you look forwarding to attending? Ronald Bradford: As with most quality conferences you can only be in one place at one time, so with multiple tracks per session it is always difficult to decide. The continued work and success with MySQL Cluster, and with a number of sessions I am sure will be popular. The features that interest me the most are around the optimizer, where there are several sessions on new features, and on the importance of backups. There are three presentations in this area to choose from.Keith Larson: Are you going to cover any of the content in your books at your MySQL Connect sessions?Ronald Bradford: I will be giving two presentations at MySQL Connect. The first will include the techniques available for creating better indexes where I will be touching on some aspects of the first Effective MySQL book on Optimizing SQL Statements.  In my second presentation from experiences of managing 500+ AWS MySQL instances, I will be touching on areas including SQL tuning, backup and recovery and scale out with replication.   These are the key topics of the initial books in the Effective MySQL series that focus on performance, scalability and business continuity.  The books however cover a far greater amount of detail then can be presented in a 1 hour session. Keith Larson: What features of MySQL 5.6 do you look forward to the most ?Ronald Bradford: I am very impressed with the optimizer trace feature. The ability to see exposed information is invaluable not just for MySQL 5.6, but to also apply information discerned for optimizing SQL statements in earlier versions of MySQL.  Not everybody understands that it is easy to deploy a MySQL 5.6 slave into an existing topology running an older version if MySQL for evaluation of many new features.  You can use the new mysqlbinlog streaming feature for duplicating master binary logs on an older version with a MySQL 5.6 slave.  The improvements in instrumentation in the Performance Schema are exciting.   However, as with my upcoming Replication Techniques in Depth title, that will be available for sale at MySQL Connect, there are numerous replication features, some long overdue with provide significant management benefits. Crash Save Slaves, Global transaction Identifiers (GTID)  and checksums just to mention a few.Keith Larson: You have been to numerous conferences, what would you recommend for people at the conference? Ronald Bradford: Make the time to meet and introduce yourself to the speakers that cover the topics that most interest you. The MySQL ecosystem has a very strong community.  The relationships you build with presenters, developers and architects in MySQL can be invaluable, however they are created over time. Get to know these people, interact with them over time.  This is the opportunity to learn more then just the content from a 1 hour session. Keith Larson: Any additional tips to handling the long hours ? Ronald Bradford: Conferences can be hard, especially with all the post event drinking.  This is a two day event and I am sure will include additional events on Friday and Saturday night so come well prepared, and leave work behind. Take the time to learn something new.   You can always catchup on sleep later. Keith Larson: Thank you so much for taking some time to do this I look forward to seeing you at the MySQL Connect conference.  Please stay tuned here for more updates on MySQL.

  • what is best book to learn optimized programming in java [closed]

    - by Abhishek Simon
    Possible Duplicate: Is there a canonical book for learning Java as an experienced developer? Let me elaborate a little: I used to be a C/C++ programmer where I used data structure concept like trees, queues stack etc and tried to optimize as much as possible, minimum no. of loops, variables and tried to make it efficient. It's been a couple of years that I started writing java codes, but it is simply not that efficient in terms of performance, memory intensive etc. To the point: I want to enter programming challenges using java so I need to improve my approach at things I program. So please suggest me some books that can help me learn to program better and have a chance in solving challenges in programming.

  • Windows Phone 7 Development &ndash; Useful Links

    - by David Turner
    Here are some excellent links for anyone developing for Windows Phone 7: J.D. Meier’s Windows Phone Developer Guidance Map – this is immense.  Also check out the Silverlight version Justin Angel’s site – some really great articles on unlocked roms, automation and Continuous Integration Windows Phone 7 Development Best Practices Wiki Jeff Blankenburg’s 31 days of Windows Phone 7 This post of Links to sample code for Windows Phone Tim Heuers blog, particularly this post of Tips and Tricks Kevin Marshall's blog, particularly the epic WP7 Development Tips Part 1 post Code Samples for Windows Phone on MSDN If you have unlocked your phone for development, then you can use the WPConnect tool to connect to the device rather than using the Zune client.  I found it useful to pin a shortcut to WPConnect in my Start Menu. The Performance Counters displayed when you debug your app on a device are useful for seeing things like frame rate and memory usage, this page on MSDN explains what the numbers mean.  Jeff Blankenburg covers this in more details on his blog I also came across this set of links to tutorials recently which looks very useful.

  • We're Back: I'm Here

    - by [email protected]
    After a busy Fall and Winter post-Oracle OpenWorld 2009 Oracle's Application Strategy Blog is back. More on what we've been up to shortly. Me, I'm blogging here for the first time. After nearly 6 years at Oracle working on the Oracle Fusion Middleware business I've recently joined the Oracle Applications team. For me, what's old is new again. Prior to working on applications infrastructure at Oracle...and at BEA Systems before that...I worked at PeopleSoft in a number of roles spanning Enterprise Performance Management, Supply Chain, Public Sector and Financial Services and more. Some of the acronyms are the same, there are (of course) some new ones too. But what I'm really excited about is the intersection of Enterprise Applications and Applications Infrastructure that's happening right now. "Aligning IT with Business Strategy" has been the buzzphrase for longer than we can all remember---but what I've seen over the past 5 months makes me start to believe that it's finally starting to happen.

  • A better way to do concurrent programming

    - by Alex.Davies
    Programming to take advantage of multicore processors is hard. If you let multiple threads access the same memory, bad things happen. To avoid this, you use the lock keyword, but if you use that in the wrong way, your code deadlocks. It's all a nightmare. Luckily, there's a better way - Actors. They're really easy to think about. They're really safe (if you follow a couple of simple rules). And high-performance, type-safe actors are now available for .NET by using this open-source library: http://code.google.com/p/n-act/ Have a look at the site for details. I'll blog with more reasons to use actors and tips and tricks to get the best parallelism from them soon.

  • T-SQL Tuesday - IO capacity planning

    - by Michael Zilberstein
    This post is my contribution to Adam Machanic's T-SQL Tuesday #004 , hosted this time by Mike Walsh . Being applicative DBA, I usually don't take part in discussions which storage to buy or how to configure it. My interaction with IO is usually via PerfMon. When somebody calls me asking why everything is suddenly so slow on database server, "disk queue length" or "average seconds per transfer" counters provide an overwhelming answer in 60-70% of such cases.

  • How do I get Flash 10.2 RC + Crystal HD for HW accelerated video to work?

    - by Gee
    I have a netbook with a N450 Atom and a BCM70012 aka Crystal HD card. On Windows 7 I can play HD flash video with very little CPU usage because of the RC of Flash 10.2. I did some reading and saw posts claiming that the Crystal HD card is finally supported by the newer Flash 10.2 RC in Ubuntu but I can't get it to work. I can confirm that flash 10.2 is loaded and used, and there's even a HW acceleration option that is enabled in the settings but performance is horrible. From what I read, the Crystal HD card is supposed to be enabled on 10.10 by default - I don't know if it is. I tried installing drivers for it in various ways but HD flash video is still a slideshow So does anyone have it working? If so, how'd you set it up?

  • Video Encoding library for C++ game

    - by Paulo Pinto
    I'm looking for a video encoding library in C++ that I can use to record game footage. It can not be an external application like Fraps, it must be a library. Ideally the encoding can be done in real time without affecting game performance too much, although this is not a must have requirement. Another preference is that the video file being saved from the game is already compressed and ready to be used by most video players without any further processing. I realize that this might not be possible especially for real time encoding, so I would accept a trade off of having to process the file later for better compression and/or better file format. I'd like to hear about your experience integrating the library into a game if possible and any interesting trade offs you had to make. Some libraries support more that one file format or codec, so advice on the file format would also be appreciated.

  • Just updated, after reboot my computer won't start up again

    - by Alex
    I have a macbook that I use on occasion which dual boots Ubuntu and OSX (It has rEFIt installed). I turned it on for the first time in a while and it needed a bunch of updates. So I let it run, and restarted it when it asked. When it was booting up, it got stuck at a light blue screen. There was nothing on the screen to indicate that it was doing anything - I figured it just got stuck or something, so I turned it off and back on. (I suspect now it was actually working, but I had no indication that it hadn't just frozen) Now I can't access either OSX or my Ubuntu partition. When I choose ubuntu on the rEFIt menu, it shows "No bootable device -- insert book disk and press key". If I try to start up OSX is looks like it starts loading, but instead of an apple logo there's a crossed out circle icon.
