  • What kind of database to use in .NET

    - by Chris
    I'm writing a program in C# that will need to store a few Data Tables on the user's computer and load them back when he restarts the program: Up to about 10000 records consisting of text and integers. I don't want to use a CSV file, and I had some trouble with SQLite. Are there any other good options to try?

  • Missing } in XML expression

    - by Chris
    I have an external javascript file that I want to, upon include, write some HTML to the end of the web page. Upon doing so though I get the error Missing } in XML expression on the line that uses dropdownhtml. Here is my code var dropdownhtml = '<div id="dropdown"></div>'; $(document).ready(function(){ //$(document).append(dropdownhtml); alert(dropdownhtml); }); The XHTML webpage that includes this file does so like this: <script type="text/javascript" src="/web/resources/js/dropdownmenu.js"></script> Doing either append or alert throws up the same error, what is going wrong?

    - by Chris
    I'm trying to store an Image in my website so I can use it easily but I found this php code from here and I can't quite make much sense of it..

    - by Chris Porter
    What's the best way to make an element of 100% minimum height across a wide range of browsers ? In particular if you have a layout with a header and footer of fixed height how do you make the middle content part fill 100% of the space in between with the footer fixed to the bottom ?

  • Kids don’t mark their own homework

    - by jamiet
    During a discussion at work today in regard to doing some thorough acceptance testing of the system that I currently work on the topic of who should actually do the testing came up. I remarked that I didn’t think that I as the developer should be doing acceptance testing and a colleague, Russ Taylor, agreed with me and then came out with this little pearler: Kids don’t mark their own homework Maybe its a common turn of phrase but I had never heard it before and, to me, it sums up very succinctly my feelings on the matter. I tweeted about it and it got a couple of retweets as well as a slightly different perspective from Bruce Durling who said: I'm of the opinion that testers should be in the dev team & the dev *team* should be responsible for quality Bruce makes a good point that testers should be considered part of the dev team. I agree wholly with that and don’t think that point of view necessarily conflicts with Russ’s analogy. Yes, developers should absolutely be responsible for testing their own work – I also think that in the murky world of data integration there is often a need for a 3rd party to validate that work. Improving testing mechanisms for data integration projects is something that is near and dear to my heart so I would welcome any other thoughts around this. Let me know if you have any in the comments! @Jamiet

(tags: oracle otn fusionmiddleware b2b) Java 2 Go!: How to write a simple yet “bullet-proof” object cache "So, while we were thinking hard to come up with the most efficient, generic and elegant way of finally implementing our weak and soft caches, Mr. Eric Chan, who is one of the main architects in Oracle Beehive team, had a very interesting breakthrough. In short terms, he thought of a very nice way of combining both WeakReference and SoftReference in our weak and soft caches so that they would provide exactly the same functionality without having to deal with those reference queues at all. Basically, instead of using a plain HashMap as our backing storage, we used a java.util.WeakHashMap in both our cache implementations. The hat trick was what and how to store things in it." - Eduardo Rodrigues (tags: oracle java sun) @jamet123: First Look – Oracle Data Mining "[Oracle Data Mining] is a nice product for Oracle database customers and well worth looking into.

  • The Social Business Thought Leaders - Steve Denning

    - by kellsey.ruppel
    How is the average organization doing? Not very well according to a number of recent books and reports. A few indicators provide quite a gloomy picture: Return on assets and invested capitals dropped to 25% of its value in 1965 in the entire US market (see The Shift Index by John Hagel) Firms are dying faster and faster with the average lifespan of companies listed in the S&P 500 index gone from 67 years in the 1920s to 15 years today (see Creative Disruption by Richard Foster) Employee engagement ratio, a high level indicator of an organization’s health proved to affect performance outcomes, does not exceed on average 20%-30% (see Employee Engagement, Gallup or The Engagement Gap, Towers Perrin) In one of the most enjoyable keynotes of the Social Business Forum 2012, Steve Denning (Author of Radical Management and Independent Management Consultant) explained why this is happening and especially what leaders should do to reverse the worrying trends. In this Social Business Thought Leaders series, we asked Steve to collapse some key suggestions in a 2 minutes video that we strongly recommend. Steve discusses traditional management - that set of principles and practices born in the early 20th century and largely inspired by thinkers such as Frederick Taylor and Henry Ford - as the main responsible for the declining performance of modern organizations. While so many things have changed in the last 100 or so years, most companies are in fact still primarily focused on maximizing profits and efficiency, cutting costs, coordinating individuals top-down through command and control. The issue is, in a knowledge intensive, customer centred, turbulent market like the one we are experiencing, similar concepts are not just alienating employees' passion but also destroying the last source of competitive differentiation left: creativity and the innovative potential. According to Steve Denning, in a phase change from old industrial to a creative, collaborative, knowledge economy, the answer is hidden in a whole new business ecosystem that puts the individual (both the employee and the customer) at the center of the organization. He calls this new paradigm Radical Management and in the video interview he articulates the huge challenges and amazing rewards our enterprises are facing during this inevitable transition.

  • FairWarning Privacy Monitoring Solutions Rely on MySQL to Secure Patient Data

    - by Rebecca Hansen
    FairWarning® solutions have audited well over 120 billion events, each of which was processed and stored in a MySQL database. FairWarning is the world's leading supplier of privacy monitoring solutions for electronic health records, relied on by over 1,200 Hospitals and 5,000 Clinics to keep their patients' data safe. In January 2014, FairWarning was awarded the highest commendation in healthcare IT as the first ever Category Leader for Patient Privacy Monitoring in the "2013 Best in KLAS: Software & Services" report[1]. FairWarning has used MySQL as their solutions’ database from their start in 2005 to worldwide expansion and market leadership. FairWarning recently migrated their solutions from MyISAM to InnoDB and updated from MySQL 5.5 to 5.6. Following are some of benefits they’ve had as a result of those changes and reasons for their continued reliance on MySQL (from FairWarning MySQL Case Study). Scalability to Handle Terabytes of Data FairWarning's customers have a lot of data: On average, FairWarning customers receive over 700,000 events to be processed daily. Over 25% of their customers receive over 30 million events per day, which equates to over 1 billion events and nearly one terabyte (TB) of new data each month. Databases range in size from a few hundred GBs to 10+ TBs for enterprise deployments (data are rolled off after 13 months). Low or Zero Admin = Few DBAs "MySQL has not required a lot of administration. After it's been tuned, configured, and optimized for size on initial setup, we have very low administrative costs. I can scale and add more customers without adding DBAs. This has had a big, positive impact on our business.” - Chris Arnold, FairWarning Vice President of Product Management and Engineering. Performance Schema  As the size of FairWarning's customers has increased, so have their tables and data volumes. MySQL 5.6’ new maintenance and management features have helped FairWarning keep up. In particular, MySQL 5.6 performance schema’s low-level metrics have provided critical insight into how the system is performing and why. Support for Mutli-CPU Threads MySQL 5.6' support for multiple concurrent CPU threads, and FairWarning's custom data loader allow multiple files to load into a single table simultaneously vs. one at a time. As a result, their data load time has been reduced by 500%. MySQL Enterprise Hot Backup Because hospitals and clinics never stop, FairWarning solutions can’t either. FairWarning changed from using mysqldump to MySQL Enterprise Hot Backup, which has reduced downtime, restore time, and storage requirements. For many of their larger customers, restore time has decreased by 80%. MySQL Enterprise Edition and Product Roadmap Provide Complete Solution "MySQL's product roadmap fully addresses our needs. We like the fact that MySQL Enterprise Edition has everything included; there's no need to purchase separate modules."  - Chris Arnold Learn More>> FairWarning MySQL Case Study Why MySQL 5.6 is an Even Better Embedded Database for Your Products presentation Updating Your Products to MySQL 5.6, Best Practices for OEMs on-demand webinar (audio and / or slides + Q&A transcript) MyISAM to InnoDB – Why and How on-demand webinar (same stuff) Top 10 Reasons to Use MySQL as an Embedded Database white paper [1] 2013 Best in KLAS: Software & Services report, January, 2014. © 2014 KLAS Enterprises, LLC.

  • EVENT RECAP: Oracle Health Sciences Conference

    - by cwarticki
    Monaco served as an intense location for this year's Oracle Health Sciences User Group conference.  It was a "Grand Prix" event with nearly 200 attendees from all over the world.  In a country famous for high performance race cars, luxury super yachts and lifestyles of the rich & famous, the conference was very Ellison-esque. I think the Superyachts were being paired with Exadata. The OSHUG staff were fantastic . Robin and Taylor (pictured left) from Drohan Management took care of all the details and were wonderful to get to know. I met with some real Oracle loyalists.  Stan Sachar,  I.T. Manager for Westat, and the Focus Group co-chair for Admin Configuration Mgmt (ACM).  Westat was an early adopter of Oracle Clinical for clinical trial projects with installations in 1997-98.  I had a chance to talk with Stan during the reception and he is an Oracle advocate and evangelist. He's invested in his career in using Oracle products. (Stan Sachar pictured right with Dick Wolnick from Oracle, on left) I also met with Mirco Becker from Grunenthal Gmbh.  He's been working with the Argus product for over 6 years.  He's a big user of Oracle Support. Mirco attended my support best practices session and was actively engaged and asked several questions.  He's excited to adopt those best practices and work more efficiently and effectively with Support. Finally, I thank the many who attended my session.  I admit, the beautiful weather and view of the ocean was a distraction, but nonetheless my mission was to provide you with all the necessary support resources for Health Sciences users. You will find a copy of my presentation on the OSHUG website. Bon Voyage Monaco.  Thanks for the memories.  I'll see everyone next year, in Miami. -Chris WartickiGlobal Customer Management

  • 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. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) dmesg | tail -f [ 14.024709] EXT4-fs (sda5): re-mounted. Opts: errors=remount-ro,commit=0 [ 14.026443] EXT4-fs (sda7): re-mounted.

  • Network(ing) to the Limit

    - by Oracle OpenWorld Blog Team
     By Karen Shamban While Oracle OpenWorld attendees are networking, there's an Oracle Global IT team that builds and maintains the massive networks that help run the show. The objective? To keep things running as seamlessly and smoothly as possible, constantly evaluate priorities, mitigate risk, and be ready for whatever might happen -- because things do happen when there are 50,000 plus attendees, tens of thousands of devices, unexpected requirements, and a constant flow of up-to-the-minute information. Here's just some of what it takes to keep the conference going, network style: 100 Oracle network, voice, and desktop engineers; security, risk management, and other IT experts, who come in from 17 countries  1000+ network switches 300+ miles of copper and fiber 485 wireless access points 2,500 wired laptops 300 VoIP phones And just where are all these networks and devices deployed? This is what the team had to build and manage: Moscone North, South, and West, including: The keynote hall Oracle DEMOgrounds in the Exhibition Halls Hundreds of session rooms Connection Centers, Social Avenue, Lounges Registration The Howard Street Tent and Taylor Street Cafe tented venues Oracle Square (Union Square) Yerba Buena Gardens Masonic Auditorium Sessions and demos at 8 hotel venues That's a whole lot of networking going on. And here's the kicker: the team has only 4 days to bring get it all up and running across these many venues, and exactly 12 hours to take it all down once the show ends. The Global IT team puts in the equivalent of 152 24-hour days for set-up, 227 24-hour days of support during the conferences, and then tears it all down in about 20 24-hour days. And in case you were wondering, the planning for next year's Oracle OpenWorld starts ... next week. No rest for the weary.  Now THAT's networking!  So hats off to the Global IT team -- the job ain't easy, but somebody's got to do it, and they do it remarkably well.

  • Make seems to think a prerequisite is an intermediate file, removes it

    - by James
    For starters, this exercise in GNU make was admittedly just that: an exercise rather than a practicality, since a simple bash script would have sufficed. However, it brought up interesting behavior I don't quite understand. I've written a seemingly simple Makefile to handle generation of SSL key/cert pairs as necessary for MySQL. My goal was for make <name> to result in <name>-key.pem, <name>-cert.pem, and any other necessary files (specifically, the CA pair if any of it is missing or needs updating, which leads into another interesting follow-up exercise of handling reverse deps to reissue any certs that had been signed by a missing/updated CA cert). After executing all rules as expected, make seems to be too aggressive at identifying intermediate files for removal; it removes a file I thought would be "safe" since it should have been generated as a prereq to the main rule I'm invoking. (Humbly translated, I likely have misinterpreted make's documented behavior to suit my expectation, but don't understand how. ;-) Edited (thanks, Chris!) Adding %-cert.pem to .PRECIOUS does, of course, prevent the deletion. (I had been using the wrong syntax.) Makefile: OPENSSL = /usr/bin/openssl # Corrected, thanks Chris! .PHONY: clean default: ca clean: rm -I *.pem %: %-key.pem %-cert.pem @# Placeholder (to make this implicit create a rule and not cancel one) Makefile: @# Prevent the catch-all from matching Makefile ca-cert.pem: ca-key.pem $(OPENSSL) req -new -x509 -nodes -days 1000 -key ca-key.pem $@ %-key.pem: $(OPENSSL) genrsa 2048 $@ %-cert.pem: %-csr.pem ca-cert.pem ca-key.pem $(OPENSSL) x509 -req -in $ $@ Output: $ make host1 /usr/bin/openssl genrsa 2048 ca-key.pem /usr/bin/openssl req -new -x509 -nodes -days 1000 -key ca-key.pem ca-cert.pem /usr/bin/openssl genrsa 2048 host1-key.pem /usr/bin/openssl req -new -days 1000 -nodes -key host1-key.pem host1-csr.pem /usr/bin/openssl x509 -req -in host1-csr.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 host1-cert.pem rm host1-csr.pem host1-cert.pem This is driving me crazy, and I'll happily try any suggestions and post results. If I'm just totally noobing out on this one, feel free to jibe away. You can't possibly hurt my feelings. :)

  • Python DictReader - Skipping rows with missing columns?

    - by victorhooi
    heya, I have a Excel .CSV file I'm attempting to read in with DictReader. All seems to be well, except it seems to omit rows, specifically those with missing columns. Our input looks like: mail,givenName,sn,lorem,ipsum,dolor,telephoneNumber [email protected],ian,bay,3424,8403,2535,+65(2)34523534545 [email protected],mike,gibson,3424,8403,2535,+65(2)34523534545 [email protected],ross,martin,,,,+65(2)34523534545 [email protected],david,connor,,,,+65(2)34523534545 chris[email protected],chris,call,3424,8403,2535,+65(2)34523534545 So some of the rows have missing lorem/ipsum/dolor columns, and it's just a string of commas for those. We're reading it in with: def read_gd_dump(input_file="blah 20100423.csv"): gd_extract = csv.DictReader(open('blah 20100423.csv'), restval='missing', dialect='excel') return dict([(row['something'], row) for row in gd_extract]) And I checked that "something" (the key for our dict) isn't one of the missing columns, I had originally suspected it might be that. It's one of the columns after that. However, DictReader seems to completely skip over the rows. I tried setting restval to something, didn't seem to make any difference. I can't seem to find anything in Python's CSV docs (http://docs.python.org/library/csv.html) that would explain this behaviour, but I may have misread something. Any ideas? Thanks, Victor
