I had this question after viewing Advice for vb.net web application structure with code generator - refactoring, rewrite, change ORM?.

Hi Mr. tablaFreak,

Actually i was looking for similar code generator that enables me to create data-intensive asp.net web application in vb.net and after reading this article i think this is the best performance approach for CRUD operations with big data, but i am really not aware of how to bind class records to write literal HTML code in the code behind as you mentioned, so kindly provide your your code generator along with few samples that can help for the same

Your assistance is highly appreciated.

Hi experts, I'm having trouble sending file to .asp server using ajax as the code shown below. I've observed that too much character could hinder the asp server not to receive, sending an error says; "The source you are looking for has been removed, had its changed or is temporarily unavailable". My question is, Is there other way forcing the server to receive big data using Ajaz like the way i used below? What approach should i use to handle big data to send .asp server? Thanks experts!

In this article, I read "Even in the optimistic scenario, just mining one bitcoin in 2020 would require a shocking 5,500 kWh, or about half the annual electricity consumption of an American household."


So, I am trying to understand what exactly is meant by "mining one bitcoin."

Does this mean looking through the entire ledger to trace the history of a single bitcoin?

How large is that ledger, in record count...

Does the BlockChain database format have any query capabilities?

Please tell me what you can, since I find this entire problem very daunting.

Hi there,

I know its kinda a ridiculous question since the Cisco Nexus Series is high end data center hardware and the Cisco SG500X is SMB. But for my home lab I am planning for the future and a good friend who runs a big data center wanted to sell me some nice Cisco Nexus Stuff. So I could get them very very cheap few hundred bucks vs. the around 1k for the SG500X-24. To be specific it would be a Nexus 5596UP with a 2248TP expension.

Would you go for the Nexus or for the SG500X? What are the gotcha's with the Nexus?

I know that the SG500X does L3 stuff out of the box. The Nexus 5596UP needs the L3 Module and the right License file for it. Also the Nexus 5596UP can't do 100MBit but I guess that's solved with the 2248TP Expension.

I'm building a Microsoft Access application with a login authentication feature, I wanted to avoid the need for users to enter a login and password each time they need the use the app and then thought of using biometrics . How can I implement the use of a biometric login to a Microsoft Access application.
I'm working on an ad campaign management app. There's a feature there advertisers can assign caps for campaign based on spending or conversions in daily, monthly or lifetime basis and there would be multiple caps per ad campaign. As soon as one campaign reaches the 80% we will send notification to all publishes and once caps are reached we have to stop the campaign immediately. We're receiving thousands of event per second. Currently what i'm doing is querying reporting table every second but it's quite inefficient and sometimes campaigns already exceeded the caps when I detect it. So my question is;

What're the existing efficient programmatic or architectural solution's in industry to handle these kind of situations?
I have large numbers PDF document, from which I need to extract text. The extracted text I use for further processing. I did this for a small subset of documents using Tesseract API in a linear approach and I get the required output. However, this takes a very long time when I have a large number of documents.

I tried to use the Hadoop environment processing capabilities (Map-Reduce) and storage (HDFS) for solving this issue. However, I am facing problem to implement Tesseract API into the Hadoop (Map-Reduce) approach. As Teserract converts the files into intermediate image files, I am confused as to how intermediate result Image files of Tesseract-API-process can be handled inside HDFS.

I have searched and unsuccesfully tried a few options earlier like:

    I have extracted text from PDF by extending FileInputFormat class into my own PdfInputFormat class using Hadoop-Map-Reduce, for this i used Apache PDFBox to extract text from pdf, but when it comes to scanned-pdf's which contains image, this solution does not give me the required results.

    I found few answers on the same topic stating to use -Fuse and that will help or one should generate image files locally and than upload those into hdfs for further processing. Not sure if this is the correct approach.

Would like to know approaches around this.

I have an audio file, many actually, that are an interview between the interviewer and interviewee.  The same person is asking questions in each file, while the people answering are different.

I need to separate the answers out by generating silence over the interview questions. I'm currently doing this by hand with audacity, but it is extremely time consuming.

Any help would be greatly appreciated.  I am a software developer, but audio is not my area, so code is am option if there isn't a program available.


copy that search into a browser
Google with videos larger than 20 minutes

I am looking for mob (like tony sprano tv show "the spranos" on hbo television) documentary about taxi drivers
Please dont completely edit search to

tony sprano taxi cab

to find tony sprano riding a taxi cab because this is an algorithm question

Tony sprano riding a taxi cab is an example to a correct answer but isnt the only correct answer to the question but please dont edit the answer too much

All the results are video games playing
People filming themselves playing xbox or playstation or nintendo

Seems like all the specific searches are something else.
So this is more of a big data question.

I usually just watch netflix.com because it is easier than something specific.
Most people just watch regular tv because tv is easy to turn on

this question is a puzzle and not looking for a link the meaning of + and - symbols
so if you have a better picture of google custom search terms that is not the answer.
Note: this question is not homework and is not a puzzle for a job interview -YET.…

I am ready introduction to oracle goldengate:



Oracle GoldenGate is a comprehensive software package for real-time data integration and replication in heterogeneous IT environments. The product set enables high availability solutions, real-time data integration, transactional change data capture, data replication, transformations, and verification between operational and analytical enterprise systems. Oracle GoldenGate 12c brings extreme performance with simplified configuration and management, tighter integration with Oracle Database, support for cloud environments, expanded heterogeneity, and enhanced security.

In addition to the Oracle GoldenGate core platform for real-time data movement, Oracle provides the Management Pack for Oracle GoldenGate—a visual management and monitoring solution for Oracle GoldenGate deployments—as well as Oracle GoldenGate Veridata, which allows high-speed, high-volume comparison between two in-use databases.

so it is for ETL and replication, but what is Oracle GoldenGate for Big Data? goldengate is not for big data, right?

please share you idea.

Hi All,

I'd like to know what kind of performance suggestion and tweak for very large VM deployment ?

I've got one VM running Tableau application which process data from multiple SQL Server databases, then it crunches the numbers before presenting it to the Executive management team.

The specs:

16x vCPU
112 GB vRAM
1 TB D:\ as Thin Provisioned VMDK on VMFS 5

somehow it is running slower every month. So what's the best practice recommendation for deploying such large VM ?

Any tips and suggestion would be greatly appreciated.
could i see the

how can individuals know which numbers not to call; if they cant see the list

I am not sure which zone this question should be in so please add zones.
We have a table that lists dates as a number (double), ie, 20170417.
We would like to place this as a date into a date field, preferably in the format YYYY-MM-DD
What's the most efficient way to accomplish this?

I am trying to find sample dataset about (cloud) storage server file access logs to conduct my research project. Can anyone please suggest any ideas or places to find this type of sample files? I think maybe something like FTP server's log dataset. because my project focus on file access not web page access.

Thanks in advance.
