  • Out of space despite lots of free space remaining

    - by Kristian Thomsen
    When upgrading Ubuntu from 11.10 to 12.04 I discovered an unexpected problem. The upgrade was stopped because there wasn't enough free space for the installation. I managed to free some space and do the upgrade but now a prompt appears after logging in saying I'm out of space. This prompt asks me if I want to examine the problem. The "Disk Usage Analyser" is opened. In the top it says: Total filesystem capacity: 47.0 GB (used: 13.5 GB available: 33.4 GB) Folder -- Usage -- Size / -- 100% -- 12.5 GB usr -- 44.8 % -- 5.6 GB home -- 30.3 % -- 3.8 GB lib -- 13.0 % -- 1.6 GB var -- 9.1 % -- 1.1 GB boot 2.5 % 309.5 GB and a lot of small contributors like: etc, opt, sbin, bin etc. I do not really understand this problem since the analyser in the top says that I have 33.4 GB left in this file system. What can I do to make Ubuntu use the remaining space? Running df -i in the terminal gives: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda7 610800 576874 33926 95% / udev 213451 563 212888 1% /dev tmpfs 218524 486 218038 1% /run none 218524 3 218521 1% /run/lock none 218524 7 218517 1% /run/shm /dev/sda8 2264752 16371 2248381 1% /home What does this mean?

  • Free Updates and Errata for Oracle Linux

    - by Lenz Grimmer
    ISO images of the Oracle Linux installation media as well as individual binary RPMs (and the sources) of major and minor releases (Updates) have always been freely available for download, use and distribution, ever since we started the Oracle Linux support program. We're now taking this a step further: in addition to the above, we will now also provide updated packages or errata for free from separate yum repositories on http://public-yum.oracle.com. If you would like to keep your Oracle Linux system up to date, you can now do so by subscribing your system to the respective "_latest" repository for your distribution, e.g. "ol6_latest" for Oracle Linux 6. See the installation instructions on the public yum front page for details on how enable these repositories. If you would like to also receive free updates to the Unbreakable Enterprise Kernel Release 2, make sure to enable the "[ol6_UEK_latest]" repository as well - updates to the kernel will be made available from this separate channel until it is included in the next set of installation media. Now what does this mean for Oracle Network Support? Getting access to the updates and errata was just one part of the offering – the following benefits will still only be available with an Oracle Linux Support Subscription only: Full indemnification against intellectual property claims. Use of base functionality in Enterprise Manager 12c for Linux and Enterprise Manager OpsCenter for provisioning, patching, management and monitoring of Oracle Linux Access to additional software channels on the Unbreakable Linux Network (ULN) (e.g. DTrace beta releases or ASM support packages) Wim also published a blog post with his take on the announcement.

  • Newbie worried about CASE tool.

    - by Jason Evans
    Hi there. I'm looking for some guidance on CASE tools and whether my concerns are valid. Recently I was in a meeting between my employer and an external software company which have a CASE tool currently in beta. They demonstrated this tool to us, showing how you build a UML model in Enterprise Architect (or something like it) and then, through their tool, that UML model is transformed into a Visual Studio project, with C# files, stored procedures for SQL Server, code for the data layer, WCF stuff, logging code and allsorts. Now, admittedly, I don't see the point in this, as in I'm not convinced it will save that much time (plus it feels like overkill). The tool authors said that a trial of the tool at another company had saved a team there 5 weeks of development time (from 6 weeks down to about 1 week) using this tool. I find the accuracy of that estimate hard to believe. My main concern is whether using this tool is going slow down my productivity. For example - Say I have a UML model which I built a VS solution from. Now, I want to rename a class method to something else; will this mean having to update the UML model first and then rebuilding the code? Is this how case tools normally work? Something I will need to check with the authors is the structure of the generated VS solution. I like the Domain Driven Design way of project structure - Infrstructure, Services, Model, etc. I doubt very much this tool will do that. Also, I've been playing around with Entity Framework Code First and think it's a great way to build the data model. I have nice repositories, unit of work classes and other design patterns that work well with EF. I have data anootations and stuff like that working great. By not having EF (the CASE tool uses it's own data layer code) I'm concerned that this tool's data layer code might not be a nice to integrate in the UoW pattern, repositories, etc. This I will need to verify when I get a closer look at the generated code. What are other people's experiences with CASE tools? Am I being paranoid about nothing? Am I being unfair - are my negativities unfounded? EDIT: I like to use TDD/BDD for building my code, and using a CASE tool looks like it will make this difficult. Again, any feedback on this would be great. Cheers. Jas.

  • Deploying SSIS to Integration Services Catalog (SSISDB) via SQL Server Data Tools

    - by Kevin Shyr
    There are quite a few good articles/blogs on this.  For a straight forward deployment, read this (http://www.bibits.co/post/2012/08/23/SSIS-SQL-Server-2012-Project-Deployment.aspx).  For a more dynamic and comprehensive understanding about all the different settings, read part 1 (http://www.mssqltips.com/sqlservertip/2450/ssis-package-deployment-model-in-sql-server-2012-part-1-of-2/) and part 2 (http://www.mssqltips.com/sqlservertip/2451/ssis-package-deployment-model-in-sql-server-2012-part-2-of-2/) Microsoft official doc: http://technet.microsoft.com/en-us/library/hh213373 This only thing I would add is the following.  After your first deployment, you'll notice that the subsequent deployment skips the second step (go directly "Select Destination" and skipped "Select Source").  That's because after your initial deployment, a ispac file is created to track deployment.  If you decide to go back to "Select Source" and select SSIS catalog again, the deployment process will complete, but the packages will not be deployed.

  • Free NOSQL database for use with C# client [closed]

    - by Mitten
    I've never used NOSQL databases before, but so far it seems like the best data storage solution for my project. I am going to implement a datamining application. The data I would like to mine is thousands of documents which cannot be imported into datamining applications. To make to import easier and faster (than importing thousands of documents) I am planning to import these documents into a NOSQL database first and when import NOSQL database into datamining software. At the very least once I have all the data in NOSQL database I should be able to code simplest datamining logic myself. Am I correct that NOSQL databases allow to creates records of data, but they don't mandate all the records to adhere to the same data schema (same column names/types in a classic table oriended SQL databases)? I think for each document I would create a row/entry/object (not sure what is the correct term is in use in NOSQL world) which would be a string id, few (columns) with unstructured text data, and a dozens of columns mostly of datetime and integer types. From its name NOSQL does not support SQL query syntax, but it support locating the object(row/entry?) by its unique id. Does NOSQL support qyuering objects using property=value syntax? Unfortunately most of free NOSQL db only support Java/C++ clients, which free NOSQL db would you recommend for a C# programmer?

  • How do you dive into large code bases?

    - by miku
    What tools and techniques do you use for exploring and learning an unknown code base? I am thinking of tools like grep, ctags, unit-tests, functional test, class-diagram generators, call graphs, code metrics like sloccount and so on. I'd be interested in your experiences, the helpers you used or wrote yourself and the size of the codebase, with which you worked with. I realize, that this is also a process (happening over time) and that learning can mean "can give a ten minute intro" to "can refactor and shrink this to 30% of the size". Let's leave that open for now.

  • How to check any undocumented methods provided by apple?

    - by Mahbubur R Aaman
    The following tools is provided by Apple dlopen dlsym objc_getClass sel_registerName objc_msgSend Those are listing Objective-C selectors, or strings. Objective-C selectors are stored in a special region of the binary, and therefore Apple could extract the content from there, and check if you've used some undocumented Objective-C methods. How to utilize these tools to find undocumented Objective-C methods? EDIT: Recently, one of my App rejected due to using one undocumented methods. -[UIDevice setOrientation] Since, selectors are independent from the class you're messaging, even if my custom class defines -setOrientation: irrelevant to UIDevice, there will be a possbility of being rejected.

  • Haskell: Best tools to validate textual input?

    - by Ana
    In Haskell, there are a few different options to "parsing text". I know of Alex & Happy, Parsec and Attoparsec. Probably some others. I'd like to put together a library where the user can input pieces of a URL (scheme e.g. HTTP, hostname, username, port, path, query, etc.) I'd like to validate the pieces according to the ABNF specified in RFC 3986. In other words, I'd like to put together a set of functions such as: validateScheme :: String -> Bool validateUsername :: String -> Bool validatePassword :: String -> Bool validateAuthority :: String -> Bool validatePath :: String -> Bool validateQuery :: String -> Bool What is the most appropriate tool to use to write these functions? Alex's regexps is very concise, but it's a tokenizer and doesn't straightforwardly allow you to parse using specific rules, so it's not quite what I'm looking for, but perhaps it can be wrangled into doing this easily. I've written Parsec code that does some of the above, but it looks very different from the original ABNF and unnecessarily long. So, there must be an easier and/or more appropriate way. Recommendations?

  • What tools to use for efficient link building?

    - by Evgeny
    As most SEO experts keep saying, it is not just the content that you have - but also a hefty amount of quality incoming links to your content that is important -- these are the two ways to get to the top of the search results. The question is where do I find the incomnig links? One way I know is Google Blog Search, it can be used to find blogs with related information to your content and some allow to leave comments. The comments usually consist of your name, e-mail and website. If you put your keyword instead of your name, then the keyword turns into a link to your website. Unfortunately most blogs put rel=nofollow on such links, but some blogs don't do that. What other ways are there to find quality pages to put keywords links back to your website? Quality link usually means: located on a page with relevant content does not have a rel=nofollow in the <a has a relevant keyword as in <a href=websitekeyword</a the page with the link has high PageRank (3+) and TrustRank
