I try the BM ILOG CPLEX Optimization Studio/Version: 22.1.1.0/Build id: Community Edition for my thesis, but the data is too large for it.
My data have 52 columns and 676 rows, after running, I got "Exception from IBM ILOG CPLEX: CPLEX Error 1016: Community Edition. Problem size limits exceeded" and it asked me to buy another version. However, its too costly for 1 time use.
So now, anyone hepl me to find a free version that i can download and run my data?
I also forgot my student IBM ID password (I ask for send an email to my mail but get nothing).
As you can read at

You could either use the Free Academic Initiative Cplex version or run Cplex in the Cloud with Free Credit

I just found Visual Studio Code (http://code.visualstudio.com) and wanted to give it a try. But when I read the license terms (yes - I really did) I saw the following point:
TIME-SENSITIVE SOFTWARE. The software will stop running on 31/12/2016 (day/month/year). You will not receive any other notice. You may not be able to access data used with the software when it stops running.
This seems a bit strange. What happens after the end of the year - in the worst case I will not be able to use it any more, or maybe it will not be free any more but I need to pay? There might be other reasons for this term - does anyone know?
This is a great question. I am a Program Manager on the Visual Studio Code team and happy to try to answer it.
Typically our pre-release software has an expiration defined in the license to encourage moving to officially released versions of products when they become available. Released products generally have different license terms, support policies, data collection policies, etc.
Visual Studio Code follows this model. It is currently in "Beta" and has a 31 Dec 2016 termination date in its license. We chose that date because we felt it was well outside the timeframe in which we would delare general availablity ("GA" or "1.0") and become an officially released product. The in product expiration helps with compliance because the product will not run after the license expires.
When we declare GA we will make two significant changes to the license. First, we are removing the termination date from the license and from the product. Second, we will allow users opt-out of data collection. VS Code will continue to be free and Insiders builds will always be Beta.
Thanks again for asking the question, I hope this explanation makes it more clear. I'll post a link to this in our wiki.
How can I find how much memory is neo4j using on in server. I know min and max memory that I have defined. I want to know the current usage. I am using Everyman Lib in my cakephp code
Oracle JDK ships with a nice tool called jVisualVM, see http://docs.oracle.com/javase/7/docs/technotes/guides/visualvm/ for details.
When starting up you can attach to local running java processes, select the one for Neo4j. This gives you access to a lot of JVM internal information, memory consumption is one of them.
The Microsoft node.js sql server driver (https://github.com/Azure/node-sqlserver) has not had any commits for 11 months. Anyone know what's going on with this effort? My company is using it actively, but has run across some issues that led me to the repo and the discovery that it seems to have been abandoned. Lots of open bugs also.
Should we give up on this driver and try another? Any recommendations?
Microsoft, please weigh in here.
I emailed the Microsoft main contributor and he was very helpful, although he did admit that officially MS has never declared one way or the other if they were going to continue support. Guess we'll wait and see.
In regards to my original problem - this info may help someone.
I was using queryRaw and listening for events to build the response. This method allows the user to submit multiple sql queries in one request (just separate them with ;). A large text datatype field was getting truncated and I couldn't figure out why. Turns out that the 'more' parameter that is supplied by the driver means that you must concatinate the return data.
Lots of trial and error when figuring out this driver.
The internal application which my team works on is currently on a version 10.y.z.build_number.
During a discussion if the next release is significant enough for 10.y+1.z.build_number or it should be 10.y.z+1.build_number I suggested that we could keep it simple and align the version numbers with the calendar.
For example the next release would be 13.8.1.build_number which stands for the 1st release for August 2013. The September one would be 13.9.1.build_number.
The idea has been discarded for now.
For a paid application I can imagine that having the 1st number is useful to easily distinguish between releases with free upgrades and major releases which require paid update. x+1.y.z would be paid and x.y+1.z would be free.
After a quick search I found Jeff Attwood's What's In a Version Number, Anyway?.
However for an unpaid internal application I cannot think of weak points for the calendar-aligned version numbers and the beauty of simplicity speaks to me. As one of the comments on Jeff Atwood's post says: Microsoft Office 2003 is a far more meaningful name than Microsoft Office 11.
The question:
Is my vision clouded by enthusiasm and are there known issues for calendar-aligned version numbers?
For an internal application, the information that the version needs to convey is the revision or commit of the sources from which said app is built.
Since you have access to the VCS managing that app sources, the version can help bug reporting like: "found in revision xxx".
That is far more valuable that a date-based tag, which can be subject to interpretation in order to find the exact version of the sources exhibiting a bug that need to be reporting.
You can combine that with any version policy you want, with tags: git, for instance, can generate a unique version number based on SHA1 + a tag. See:
"Deriving application build version from git describe - how to get a relatively straightforward string?"
"Simulating a global revision number with git"
But the idea remains: date is a metadata managed by a VCS or a build scheduler like Jenkins/Hudson/TeamCity... It doesn't have to be in the public version number of the app.
What need to be in that version number is an info allowing to get the exact sources from which that app was built.
I have a question regarding SCORM report generation.
I have tried to load some SCORM 2004 packages in moodle and I saw tracks in database that stores questions and learner_response.
But my question is can we implement functionality of storing each option of multi choice questions like articulate shows in it features.(http://www.articulate.com/products/ao-features.php - See individual answers section in which whole options are being displayed.).
I am aware that only interactions get recorded in db. Can SCORM supports feature of storing whole options of multichoice questions?
How are you launching your SCORM 2004 courses in Moodel? Are you using the SCORM Cloud Moodle mod to play your SCORM 2004 courses in Moodle? If so, you can find the data that you're looking for in the Reportage section of SCORM Cloud in the "All Interactions" report. More information on the Moodle Mod is located here.
