  • High Jinks, Hi Jacks, Exceptional DBA Awards and PASS

    - by Rodney
    The countdown to PASS has counted down.  The day after tomorrow I will board a plane, like many others, on my way for the 4th year in a row to SQL PASS Summit.  The anticipation has been excruciating but luckily I have this little thing called a day job as a DBA that has kept me busy and not thinking too much about the event. Well that is not exactly true since my beautiful wife works for PASS so we get to talk about SQL from the time we wake up until late in the evening. I would not have it any other way and I feel very fortunate to be a part of this great event and to have been chosen as the Exceptional DBA Award judge also for the 4th year in a row.  This year, I will have been again tasked with presenting the award to the winner, Mr. Jeff Moden and it will be a true honor to meet him in person as I have read many of his articles on SSC and have attended his session at PASS previously.  The speech is all ready but one item remains, which will be a surprise to all who attend the party on Tuesday night in Seattle (see links below).  Let's face it, Exceptional DBAs everywhere work very hard protecting our data stores, tuning queries, mentoring, saving money, installing clusters, etc and once in a while there is time to be exceptionally non-professional and have a bit of fun. Once incident that happened this year that falls under the High Jinks category was when my network admin asked if I could Telnet into a SQL instance and see if I could make the connection through the firewall that he had just configured. I was able to establish a connection on port 1433 and it occurred to me that it would be very interesting if I could actually run T-SQL queries via a Telnet session much like you might do with an SMTP server. With that thought, I proceeded to demonstrate this could be possible by convincing my senior DBA Shawn McGehee that I was able to do so. At first he did not believe me. It shook his world view.  It was inconceivable.  What I had done, behind the scenes, of course, was to copy and rename SQLCMD.exe to Telnet.exe and used it to connect and run a simple, "Select * from sys.databases" on the SQL instance. I think if it had been anyone other than Shawn I could have extended this ruse indefinitely but he caught on within 30 seconds. It was a fun thirty seconds though. On the High Jacks side of the house, which is really merged to be SQL HACKS, I finally, after several years of struggling with how to connect to an untrusted domain like in a DMZ with a windows account in SSMS, I stumbled upon a solution that does away with the requirement to use SQL Authentication.  While "Runas" is a great command to use to run an application with a higher privileged account, I had not previously been able to figure out how to connect to the remote domain with SSMS and "Runsas". It never connected and caused a login failure every time for the remote windows domain account. Then I ran across an option for "Runas",   "/netonly".  This option postpones the login until a connection is made and only then passes the remote login you supply when you first launch SSMS with the "Runas" command. So a typical shortcut would look like: "C:\Windows\System32\runas.exe /netonly /user:remotedomain.com\rodlandrum "C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\Ssms.exe" You will want to make sure the passwords are synced between the two domains, your local domain and the remote domain, otherwise you may have account lockout issues, but I have found in weeks of testing this is a stable solution. Now it is time to get ready to head for Seattle. Please, if you see me (@SQLBeat) or my wife (@Karlakay22) please run up and high five me (wait..High Jinks.High Jacks.High Fives.Need to change the title) or give me a big bear hug if you are strong enough to lift me off the ground. And if you do actually do that, I will think you are awesome and will not embarrass you by crying out for help or complaining of a broken back or sciatic nerve damage. And now the links to others who have all of the details. First, for the MVP Deep Dives 2, of which, like John, I was lucky enough to be able to participate in this year. http://www.simple-talk.com/community/blogs/johnm/archive/2011/09/29/103577.aspx And the details of the SSC party where the Exceptional DBA of 2011, Jeff Moden, will be awarded. http://www.simple-talk.com/community/blogs/rebecca_amos/archive/2011/10/05/103661.aspx   Cheers!

  • Sql Server Prevent Saving Changes That Require Table to be Re-created

    When working with SQL Server Management studio, if you use the Design view of a table and attempt to make a change that will require the table to be dropped and re-added, you may receive an error message like this one: Saving changes is not permitted.  The changes you have made require the following tables to be dropped and re-created.  You have either made changes to a table that cant be re-created or enabled the option Prevent saving changes that require the table to be re-created. In truth, its quite likely that you didnt enable such an option, despite the error dialogs accusations, as it is enabled by default when you install SQL Management Studio.  You can learn more about the issue in the KB article, Error message when you try to save a table in SQL Server 2008: Saving changes is not permitted. Warning: As the above article states, it is not recommended that you turn off this option (at least not permanently), as it will ensure that you do not accidentally change the schema of a table such that data is lost.  Do so at your peril. The simplest way to bypass this error is to go into Option Designers and uncheck the option Prevent saving changes that require table re-creation.  See the screenshot below. The main reason why you will see this error is if you attempted to do any of the following to the table whose design you are saving: Change the Allow Nulls setting for a column Reorder columns Change any columns data type Add a new column The recommended workaround is to script out the changes to a SQL file and execute them by hand, or to simply write out your own T-SQL to make the changes. Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • CLR 4.0: Corrupted State Exceptions

    - by Scott Dorman
    Corrupted state exceptions are designed to help you have fewer bugs in your code by making it harder to make common mistakes around exception handling. A very common pattern is code like this: public void FileSave(String name) { try { FileStream fs = new FileStream(name, FileMode.Create); } catch (Exception e) { MessageBox.Show("File Open Error"); throw new Exception(IOException); } The standard recommendation is not to catch System.Exception but rather catch the more specific exceptions (in this case, IOException). While this is a somewhat contrived example, what would happen if Exception were really an AccessViolationException or some other exception indicating that the process state has been corrupted? What you really want to do is get out fast before persistent data is corrupted or more work is lost. To help solve this problem and minimize the chance that you will catch exceptions like this, CLR 4.0 introduces Corrupted State Exceptions, which cannot be caught by normal catch statements. There are still places where you do want to catch these types of exceptions, particularly in your application’s “main” function or when you are loading add-ins.  There are also rare circumstances when you know code that throws an exception isn’t dangerous, such as when calling native code. In order to support these scenarios, a new HandleProcessCorruptedStateExceptions attribute has been added. This attribute is added to the function that catches these exceptions. There is also a process wide compatibility switch named legacyCorruptedStateExceptionsPolicy which when set to true will cause the code to operate under the older exception handling behavior.

  • Oracle Applications Global User Experience

    - by ultan o'broin
    Today, we're launching Oracle's first ever blog for global user experience (UX) applications issues. We'll be talking about how we design and develop applications for global use, looking at the cultural factors, internationalization (I18n), localization (L10n) and language used for a start. We will also discuss how we study and work with real users so that our customers have applications that allow them to be productive regardless of where they are located in the world. In addition, we will inform you about any globally-related events we know about, and about product features, development frameworks, tools, information and relevant to our worldwide customers. Also, of course, we hope to hear from you, too. If you have anything you want to know about our global user experience, a localization you'd like, or cultural feature you think would be useful, then let us know. If you have any tips or guidelines you'd like to share in this space, then this blog is for you too! As far as global user experience is concerned, you don't have to be lost in translation. Hence the name of the blog!

    - by Levente Nagy
    I am totally new to Linux, i installed it yesterday, since than i my fans are really loud, i did not have this problem on windows. I saw this post on this site How to control fan speed? But i am totally lost with it because im a new user to Ubuntu when i arrive to that page i see these lucid (utils): utilities to read temperature/voltage/fan sensors 1:3.1.2-2: all precise (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu1: all quantal (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu2: all raring (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.2-2ubuntu1: all saucy (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all trusty (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all So what is lucid? trusty? saucy? and other? i thought its some kind if a ubuntu type (sorry for beeing silly here) i checked my ubuntu version it just says Ubuntu 12.10 So which one i need to download? I saw there are terminal commands, im new to that too, will it cause some problem if i just copy and paste? PS: I saw my graphics card is undetected as well i have a ATI Mobility radeon HD 3200, could that cause the problem too?

  • Advice on a good comeback strategy after years of java abstinence

    - by simou
    It's almost 5 yrs since I left the java IT-project/enterprise business. Before I was a highly skilled enterprise developer / OO architect with more than 10 years experience in the business. I was proficient in many of those enterprise related technologies, including DWHing. Since then I haven't been doing any large scale programming, a little bit of C, Python, some dips into Scala, hacking a small java-plugin framework, opengl, but only as fun projects. Now I want to re-enter the java stage again, i.e. I'm looking for job opportunities as a developer. But I fear I might have lost much of my former punching strength, e.g. I would have to give my SQL knowledge a deep refreshing breath, re-visit basic stuff like design patterns, enterprise architectures, etc. and probably learn the new stuff like EJB3.1, JEE 6 too. I also missed the whole scrum craze. So from your own experience, what subject should I tackle first? Like technology (which ones?) or design skills (uml..)? But what I'm also wondering is since the basic design / architectural principles haven't changed much by now, what would be the chance on the job market for someone like me who left the java-world at a time where everything was less fragmented and EJB2.1 and XDoclet were de-facto standards? And how could I convince a potential employer that I'm still an effective on-the-job learner? Should I rather aim for "junior positions" ? Lots of questions but I'd be really glad if you could share your (encouraging :) thoughts with me. cheers! (btw I'm based in Austria)

  • KERPOOOOW!

    - by Matt Christian
    Recently I discovered the colorful world of comic books.  In the past I've read comics a few times but never really got into them.  When I wanted to start a collection I decided either video games or comics yet stayed away from comics because I am less familiar with them. In any case, I stopped by my local comic shop and picked up a few comics and a few trade paperbacks.  After reading them and understanding their basic flow I began to enjoy not only the stories but the art styles hiding behind those little white bubbles of text (well, they're USUALLY white).  My first stop at the comic store I ended up with: - Nemesis #1 (cover A) - Shuddertown #1 (cover A I think) - Daredevil: King of Hell's Kitchen Trade Paperback - Peter Parker: Spiderman - One Small Break Trade Paperback It took me about 3-4 days to read all of that including re-reading the single issues and glancing over the beginning of Daredevil again.  After a week of looking around online I knew a little more about the comics I wanted to pick up and the kind of art style I enjoyed.  While Peter Parker: Spiderman was ok, I really enjoyed the detailed, realistic look of Daredevil and Shuddertown. Now, a few years back I picked up the game The Darkness for PS3.  I knew it was based off a comic but never read the comic.  I decided I'd pick up a few issues of it and ended up with: - The Darkness #80 (cover A) - The Darkness #81 (cover A) - The Darkness #82 (cover A) - The Darkness #83 (cover A) - The Darkness Shadows and Flame #1  (one-shot; cover A) - The Darkness Origins: Volume 1 Trade Paperback (contains The Darkness #1-6) - New Age boards and bags for storing my comics The Darkness is relatively good though jumping from issue #6 to issue #80 I lost a bit on who the enemy in the current series is.  I think out of all of them, issue #83 was my favorite of them. I'm signed up at the local shop to continue getting Nemesis, The Darkness, and Shuddertown, and I'll probably pick up a few different ones this weekend...

  • File format for animated scene

    - by stephelton
    I've got a custom OpenGL based rendering engine and I'd like to add support for cinema-type scene animation. The artist that is helping me uses primarily 3DSMax. I'd like a file format for exporting and importing this data. I'm also in need of a file format for skeletal animation data, which may have an impact here. I've been looking at MAXScript to manually export this stuff, which would buy me the most flexibility, but I have virtually no experience with 3DSMax itself, so I get a little lost when it comes to terminology. So I'd like to know what file formats exist for animated scene data, and whether they are appropriate for my use (my fear is that they will be way too broad for my fairly simple needs.) The way I view animated scene data is basically a bunch of references to [animated] models with keyframe-based matrices describing their orientation over time. And probably some special camera stuff to handle perspective. I might also want some event type stuff for adding/removing objects. Is this a sane concept?

  • Ranking hit after WP site migration

    - by Ben
    I migrated my site from its old domain over a month ago. I followed WMT completely, including 301 redirects from every existing URL to the new domain, and then submitting a change of address. Traffic continued as normal, but then a few days after submitting the change of address traffic plummeted to about 20-30% of what it was previously. Most of my traffic come from organic search, and I can see that for the keywords I had targeted before and performed well with and am now ranking much much lower for. In some cases for low competition keywords I've only lost a few places, for higher competition terms I have really suffered. This has started to pick up a bit (one of my keywords I have risen from 195 to 100 in the last week), but it seems to be a very slow process. How seamless is this process normally? I was under the impression that this would not affect my rankings too severely, but it has now been a month since the move and recovery seems to be very slow, if at all. Is it likely that I've missed something? The only change is that I have moved what was the home page to be more of a sub-page, and now in its place is a magazine-style home page. I understand that links to the old site will now be pointing to the latter which means that rankings for some keywords attributed to the old home page will take a hit, but even on other pages that seem to fit in exactly the same page structure as the previous site I have seen a drop in rankings. Any help would be greatly appreciated. Thanks!

  • How to Set Ubuntu 12.04 to it's factory settings like when u first installed it?

    - by Cameron
    Well, this is a simple answered question, from the title, but my real problem is hard af. I have set ubuntu to use root, then it wouldn't let me log into the admin account only root and guest I deleted the admin account, remade another, then attempted to disable root account. This failed - I messed up the password, the original password was "root" I also didn't set a password for my new admin account, so It says it has one, whats the default password for it? I can't moderate my ubuntu system at all now. I have tried to drop to cmd shell thing, it asks for the root password, i type 'root' and any other possible passwords, it doesn't work. To reset ubuntu to factory settings i have found that i could enter the following code: sudo dpkg-reconfigure -phigh -a sudo Requires admin password, that I cant find out without root password and I don;t know. My goal is to try to fix this without remaking a bootable usb for ubuntu, because I lost the one i made for this. so If i can't, please say so. If you can help thanks!

  • What characteristic of a software determines its operational scope?

    - by Dark Star1
    How can I classify whether a software is a medium with the ability to grow into an enterprise level software or whether it is already there? And how should I use the information to choose the appropriate language/tool to create the software? At first I was asking whether Java or PHP is the best tool to design enterprise level software, however I've suddenly realized that I am unable to put the software I'm tasked with redesigning into the proper scope so I'm lost. Edit: I guess I'm looking for tell tale signs in software that may tip the favour towards enterprise level type software in the sense of functional and operational characteristics; functional: what it does (multi-functional), Architectural characteristics such as highly modular. operational: multi-sourced and multi-homed, databases, e.t.c. To be honest the reason I ask is because I'm skeptical about the use of PhP to design a piece of employee and partial accounting software. I'm more tipping towards the use of JSP and an hmvc framework such as JSF, wickets, e.t.c. where as the other guy wants to go the PhP way although I'm not experienced with PhP, as far as I know it's not an OO oriented language hence my skepticsm towards it.

  • I can't install Ubuntu on my Dell Inspiron 15R at all

    - by Kieran Rimmer
    I'm attempting to install Ubuntu 12.04LTS, 64 bit onto a Dell Inspiron 15R laptop. I've shrunk down one of the windows partitions and even used gparted to format the vacant space as ext4. However, the install disk simply does not present any options when it comes to the partitioning step. What I get is a non-responsive blank table As well as the above, I've changed the BIOS settings so that USB emulation is disabled (as per Can't install on Dell Inspiron 15R), and changed the SATA Operation setting to all three possible options. Anyway, the install CD will bring up the trial version of ubuntu, and if I open terminal and type sudo fdisk -l, I get this: Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xb4fd9215 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 29044735 14481408 7 HPFS/NTFS/exFAT /dev/sda3 29044736 1005142015 488048640 7 HPFS/NTFS/exFAT /dev/sda4 1005154920 1953520064 474182572+ 83 Linux Disk /dev/sdb: 32.0 GB, 32017047552 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62533296 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xb4fd923d Device Boot Start End Blocks Id System /dev/sdb1 2048 16775167 8386560 84 OS/2 hidden C: drive If I type 'sudo parted -l', I get: Model: ATA WDC WD10JPVT-75A (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 41.1MB 41.1MB primary fat16 diag 2 41.9MB 14.9GB 14.8GB primary ntfs boot 3 14.9GB 515GB 500GB primary ntfs 4 515GB 1000GB 486GB primary ext4 Model: ATA SAMSUNG SSD PM83 (scsi) Disk /dev/sdb: 32.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 8589MB 8588MB primary Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

  • Building Single Page Apps on the Microsoft Stack

    - by Stephen.Walther
    Thank you everyone who came to my talk last night on Building Single Page Apps on the Microsoft Stack. I’ve attached the slides and code samples below. Here’s a quick summary of the talk. I argued that Single Page Apps are better than traditional Server Side Apps because: Single Page Apps are Stateful – In a traditional server-side app, whenever you navigate to a new page, all of your previous state is lost. It is like rebooting your computer whenever you perform any action In a Single Page App, Your Presentation Layer is Not Miles Away – In a traditional server-side app, because everything happens on the server, your presentation layer is separated from the user by space and time. In a Single Page App, the presentation layer is in the browser and not the server (which is the right place for a presentation layer). A Single Page App Respects the Web – It is easier to take advantage of HTML5 and related standards when building a Single Page App. Next, I recommended using the following four technologies when building a web application: Knockout – This is how you create your presentation layer. ASP.NET Web API – This is how you expose JSON data from your web server and perform server-side validation. HTML5 – This is how you implement client-side validation. Sammy – This is how you implement client-side routing and create a Single Page App with multiple virtual pages. There are code samples in the download (look in the Samples folder) which demonstrate how all of these technologies work when building Single Page Apps. Powerpoint Sample Code

  • How do I stop my ethernet network connection from dropping?

    - by Sean Hill
    My ethernet-based network connection doesn't stay up consistently. I'm running a ping against the gateway and it will: Work for a minute Freeze, time out, or give multi-second response times Repeat If it's stuck and I disable/enable networking through the network manager applet everything will work fine again for a minute. After 280 packets transmitted I'm getting 41% packet loss. I've tried a different cable and connection to the gateway but this had no effect. The distance to the gateway is just about 3 feet. Seems to work fine if I switch over to Windows, but Ubuntu is my main OS and I can't even use it right now as I depend on the network. My setup... OS: Ubuntu 11.04, dual-booting Windows 7 Mobo: Gigabyte Z68X-UD4-B3 CPU: Intel Core i7 2600K Edit A little clarification... Network Manager is still showing me as connected, but I am unable to reach to gateway or anything beyond. At no point does NM suggest the connection is lost and calling ifconfig shows that I still have an IP address. I tried connecting to a different gateway with a different cable and the same problem arises. As requested: lspci | grep -i eth 07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • Ubuntu...I love you, I hate you

    - by gregarobinson
     I have been working on seeing if a .NET 3.5 application will port over to Linux, Ubuntu to be specific. I started with version 9.01, then 9.10 and now 10.04 as I find more and more that I need from Mono. I have a dual boot on a dev box, Windows 7 and Ubuntu. An upgrade from Ubuntu 9.01 to 9.10 caused my mouse and keyboard to lock up. I was able to boot from a 9.10 cd. Then, I upgraded to 10.04 as I needed Mono 2,2. Upgrade worked, lost my windows boot though. it seems grub somehow jumped in and messed up the windows boot. After Googlign liek crazy and trying this and that, these 2 links finally got me my windows boot back:http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector http://support.microsoft.com/kb/927392So, I am now thinking about trying SuSe instead as I hear\read it's more stable. I think a lot of my pains have been related to learning and getting use to Linux.

    Good day, I'm currently finding out why I have lost all of my website's rank in google. I don't even appear in google results by the domain. But other sites do link me and they appear in the google results. I think it's all about leaving my site two months alone and finding out I had 20k in comment spam, which I completely deleted and fixed with filters and adding a new Disqus comment service. Thing is, I added my site to Google Webmaster Tools and I'm finding out several awful things. For example, when I click in Google Fetch As GoogleBot. I receive this error message below in response to my request. And I don't even know what's the real problem and how to fix it. I simply don't get it. This is what appears: Date: Wednesday, July 20, 2011 9:43:35 AM PDT Googlebot Type: Web Download Time (in milliseconds): 55 HTTP/1.1 403 Forbidden Date: Wed, 20 Jul 2011 16:43:36 GMT Server: Apache Vary: Accept-Encoding Content-Encoding: gzip Content-Length: 248 Keep-Alive: timeout=2, max=100 Connection: Keep-Alive Content-Type: text/html; charset=iso-8859-1 403 Forbidden Forbidden You don't have permission to access / on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request. Do you guys know anything about this problem ? I need to have Google crawl my site again. I used to have a really nice google result in the past three years. Now, there's nothing. thanks,

  • The Arab HEUG is now a reality, and other random thoughts

    - by user9147039
    I just returned from Doha, Qatar where the first of its kind HEUG (Higher Education User Group) meeting for institutions in the Middle East and North Africa was held at Qatar University and jointly hosted by Damman University from Saudi Arabia. Over 80 delegates attended including representation from education institutions in Oman, Saudi Arabia, Lebanon, and Qatar. There are many other regional HEUG organizations in place (in Australia/New Zealand, APAC, EMEA, as well as smaller regional HEUG’s in the Netherlands, South Africa, and in regions of the US), but it was truly an accomplishment to see this Middle East/North Africa group organize and launch their chapter with a meeting of this quality. To be known as the Arab HEUG going forward, I am excited about the prospects for sharing between the institutions and for the growth of Oracle solutions in the region. In particular the hosts for the event (Qatar University) did a masterful job with logistics and organization, and the quality of the event was a testament to their capabilities. Among the more interesting and enlightening presentations I attended were one from Dammam University on the lessons learned from their implementation of Campus Solutions and transition off of Banner, as well as the use by Qatar University E-business Suite for grants management (both pre-and post-award). The most notable fact coming from this latter presentation was the fit (89%) of e-Business Suite Grants to the university’s requirements. In a few weeks time we will be convening the 5th meeting of the Oracle Education & Research Industry Strategy Council in Redwood Shores (5th since my advent into my current role). The main topics of discussion will be around our Higher Education Applications Strategy for the future (including cloud approaches to ERP (HCM, Finance, and Student Information Systems), how some cases studies on the benefits of leveraging delivered functionality and extensibility in the software (versus customization). On the second day of the event we will turn our attention to Oracle in Research and also budgeting and planning in higher education. Both of these sessions will include significant participation from council members in the form of panel discussions. Our EVP’s for Systems (John Fowler) and for Global Cloud Services and North America application sales (Joanne Olson) will join us for the discussion. I recently read a couple of articles that were surprising to me. The first was from Inside Higher Ed on October 15 entitled, “As colleges prepare for major software upgrades, Kuali tries to woo them from corporate vendors.” It continues to disappointment that after all this time we are still debating whether it is better to build enterprise software through open or community source initiatives when fully functional, flexible, supported, and widely adopted options exist in the marketplace. Over a decade or more ago when these solutions were relatively immature and there was a great deal of turnover in the market I could appreciate the initiatives like Kuali. But let’s not kid ourselves – the real objective of this movement is to counter a perceived predatory commercial software industry. Again, when commercial solutions are deployed as written without significant customization, and standard business processes are adopted, the cost of these solutions (relative to the value delivered) is quite low, and certain much lower than the massive investment (and risk) in in-house developers to support a bespoke community source system. In this era of cost pressures in education and the need to refocus resources on teaching, learning, and research, I believe it’s bordering on irresponsible to continue to pursue open-source ERP. Many of the adopter’s total costs are staggering and have little to show for their efforts and expended resources. The second article was recently in the Chronicle of Higher Education and was entitled “’Big Data’ Is Bunk, Obama Campaign’s Tech Guru Tells University Leaders.” This one was so outrageous I almost don’t want to legitimize it by referencing it here. In the article the writer relays statements made by Harper Reed, President Obama’s former CTO for his 2012 re-election campaign, that big data solutions in education have no relevance and are akin to snake oil. He goes on to state that while he’s a fan of data-driven decision making in education, most of the necessary analysis can be accomplished in Excel spreadsheets. Yeah… right. This is exactly what ails education (higher education in particular). Dozens of shadow and siloed systems running on spreadsheets with limited-to-no enterprise wide initiatives to harness the data-rich environment that is a higher ed institution and transform the data into useable information. I’ll grant Mr. Reed that “Big Data” is overused and hackneyed, but imperatives like improving student success in higher education are classic big data problems that data-mining and predictive analytics can address. Further, higher ed need to be producing a massive amount more data scientists and analysts than are currently in the pipeline, to further this discipline and application of these tools to many many other problems across multiple industries.

  • Hybrid Graphics on Windows 7/Ubuntu 12.04 Dual Boot

    - by Noob.
    Alright, so here's the situation: I am using an ASUS UL80VT with two graphics cards: Integrated intel graphics and NVIDIA G210M I was running an Ubuntu 12.04 - Windows 7 dual boot (on separate partitions).The machine worked perfectly (including the display drivers) without me needing to install anything special or change any settings. However, my hard drive was corrupted and I lost all my data yesterday, so after it was replaced, I installed Ubuntu 12.04 64x again after installing Windows 7. I booted up Ubuntu after installation, and noticed it was by default using Unity 2D... Gnome 3.4 wasn't working properly either, so I guessed that the NVIDIA G210M driver wasn't installed/working and the OS was instead using the integrated graphics. I checked the "Additional Drivers" thing, but there were no proprietary drivers listed there, so I went to the NVIDIA website, downloaded the driver directly and installed it. I restarted, but there was no change. After this, I read somewhere that I should change my SATA in the BIOS to "Compatible" rather than "Enhanced". This worked fine and fixed the problem (both Unity and Gnome were working perfectly) but then when I tried booting up Windows 7, I recieved the BSOD. So I changed it back to Enhanced, and once again, the NVIDIA 210M graphics isn't working on Ubuntu, but on Windows 7 it is. I do not want to keep changing from Enhanced to Compatible every time I reboot to Ubuntu and neither do I want to simply just use one OS. Note that NVIDIA 210M and integrated graphics work perfectly on Windows 7. Also, I don't care about switching between them, I just want to be able to use the NVIDIA one. What can I do so that both Windows 7 and Ubuntu work and NVIDIA G210M works on Ubuntu?

  • IT Optimization Plan Pays Off For UK Retailer

    - by [email protected]
    I caught this article in ComputerworldUK yesterday. The headline talks about UK-based supermarket chain Morrisons is increasing their IT spend...OK, sounds good. Even nicer that Oracle is a big part of that. But what caught my eye were three things: 1) Morrison's truly has a long term strategy for IT. In this case, modernizing and optimizing how they use IT for business advantage. 2) Even in a tough economic climate, Morrison's views IT investments as contributing to and improving the bottom line. Specifically, "The investment in IT contributed to a 21 percent increase in Morrison's underlying profit.." 3) The phased, 3-year "Optimization Plan" took a holistic approach to their business--from CRM and Supply Chain systems to the underlying application infrastructure. On the infrastructure front, adopting a more flexible Service-Oriented Architecture enabled them to be more agile and adapt their business and Identity Management helped with sometimes mundane (but costly) issues like lost passwords and being able to document who has access to what. Things don't always turn out so rosy. And I know it was a long and difficult process...but it's nice to see a happy ending every once in a while.

  • Scale a game object to Bounds

    - by Spikeh
    I'm trying to scale a lot of dynamically created game objects in Unity3D to the bounds of a sphere collider, based on the size of their current mesh. Each object has a different scale and mesh size. Some are bigger than the AABB of the collider, and some are smaller. Here's the script I've written so far: private void ScaleToCollider(GameObject objectToScale, SphereCollider sphere) { var currentScale = objectToScale.transform.localScale; var currentSize = objectToScale.GetMeshHierarchyBounds().size; var targetSize = (sphere.radius * 2); var newScale = new Vector3 { x = targetSize * currentScale.x / currentSize.x, y = targetSize * currentScale.y / currentSize.y, z = targetSize * currentScale.z / currentSize.z }; Debug.Log("{0} Current scale: {1}, targetSize: {2}, currentSize: {3}, newScale: {4}, currentScale.x: {5}, currentSize.x: {6}", objectToScale.name, currentScale, targetSize, currentSize, newScale, currentScale.x, currentSize.x); //DoorDevice_meshBase Current scale: (0.1, 4.0, 3.0), targetSize: 5, currentSize: (2.9, 4.0, 1.1), newScale: (0.2, 5.0, 13.4), currentScale.x: 0.125, currentSize.x: 2.869114 //RedControlPanelForAirlock_meshBase Current scale: (1.0, 1.0, 1.0), targetSize: 5, currentSize: (0.0, 0.3, 0.2), newScale: (147.1, 16.7, 25.0), currentScale.x: 1, currentSize.x: 0.03400017 objectToScale.transform.localScale = newScale; } And the supporting extension method: public static Bounds GetMeshHierarchyBounds(this GameObject go) { var bounds = new Bounds(); // Not used, but a struct needs to be instantiated if (go.renderer != null) { bounds = go.renderer.bounds; // Make sure the parent is included Debug.Log("Found parent bounds: " + bounds); //bounds.Encapsulate(go.renderer.bounds); } foreach (var c in go.GetComponentsInChildren<MeshRenderer>()) { Debug.Log("Found {0} bounds are {1}", c.name, c.bounds); if (bounds.size == Vector3.zero) { bounds = c.bounds; } else { bounds.Encapsulate(c.bounds); } } return bounds; } After the re-scale, there doesn't seem to be any consistency to the results - some objects with completely uniform scales (x,y,z) seem to resize correctly, but others don't :| Its one of those things I've been trying to fix for so long I've lost all grasp on any of the logic :| Any help would be appreciated!

  • Distributed transactions and queues, ruby, erlang

    - by chrispanda
    I have a problem that involves several machines, message queues, and transactions. So for example a user clicks on a web page, the click sends a message to another machine which adds a payment to the user's account. There may be many thousands of clicks per second. All aspects of the transaction should be fault tolerant. I've never had to deal with anything like this before, but a bit of reading suggests this is a well known problem. So to my questions. Am I correct in assuming that secure way of doing this is with a two phase commit, but the protocol is blocking and so I won't get the required performance? It appears that DBs like redis and message queuing system like Rescue, RabbitMQ etc don't really help me a lot - even if I implement some sort of two phase commit, the data will be lost if redis crashes because it is essentially memory-only. All of this has led me to look at erlang - but before I wade in and start learning a new language, I would really like to understand better if this is worth the effort. Specifically, am I right in thinking that because of its parallel processing capabilities, erlang is a better choice for implementing a blocking protocol like two phase commit, or am I confused?

  • How to disable "N" Wireless Mode RTL8192 (Thinkpad Edge 15 Core i5) in natty

    - by Gustavo Rubio
    I've seen many owners of thinkpad edges which are supossed to be linux-friendly having problems with wireless adapter. I've found several links inside askubuntu and in ubuntuforums which have a lot of work-arounds for those problems, mine seems to be wierd though. I use my laptop on both my office and at home. At home I have a router which is A/B/G and here at home the wireless connection works just fine, using a WEP key. But in work I have a B/G/N wireless router and it doesn't work, my guess is that this adapter works with N modes but somehow this is buggy in the bundled driver in natty. I've tried to disable the "N" mode in the router but that didn't work. Later I went to realtek website, downloaded their driver and compiled myself, kinda seems to work most of the time but sometimes some websites keep trying to load or load just parts of it and images start to look like their links are broken and so on, much like what you get when you were loading a page and suddenly the connection is lost. This problem, as I said, is only using the realtek driver from their website. Dmesg gives me this a lot of these: [ 5869.049454] rtl8192se_update_ratr_table: ratr_index=0 ratr_table=0x00000ff5 [ 5879.240563] DHCP pkt src port:68, dest port:67!! So I thougth I might as well switch back to the original driver which seems to work just fine on A/B/G wireless networks but not on N networks so if anybody knows how to disable that mode from within the driver please let us know :) Thanks in advance! PS: I do found a link to a similar question and it was answered but let me remind you I'm NOT using the intel version of wireless for my thinkpad but the realtek (RTL8192SvB)

  • How To Backup Of MySQL Database Using PhpMyAdmin

    - by Jyoti
    It is very important to do backup of your MySql database, you will probably realize it when it is too late. A lot of web applications use MySql for storing the content. This can be blogs, and a lot of other things. When you have all your content as html files on your web server it is very easy to keep them safe from crashes, you just have a copy of them on your own PC and then upload them again after the web server is restored after the crash. All the content in the MySql database must also be backed up. If you have spent a lot of time making the content and it is only stored in the Mysql server, you will feel very bad if it gets lost for ever. Backing it up once every month or so makes sure you never loose too much of your work in case of a server crash, and it will make you sleep better at night. It is easy and fast, so there is no reason for not doing it. Step 1: Log into phpMyAdmin on your server. Step2: You can select the database that you would like to backup from the drop-down menu called Database. Step 3: A new page will be loaded in phpMyAdmin showing the selected database. In order to proceed with the backup click on the Export tab. Step 4: The options that you should select apart from the default ones are Save as file which will save the file locally to your computer in an .sql format and Add DROP TABLE which will add the drop table functionality if the table already exists in the database backup as shown below. Step 5: Click on the Go button to start the export/backup procedure for your database. A download window will pop up prompting for the exact place where you would like to save the file on your local computer. It is possible that the download starts automatically. This depends on your browser’s settings.
