Big data describes data sets that are so large or complex that traditional data processing applications are inadequate. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization, querying and information privacy. The term often refers simply to the use of predictive analytics or certain other advanced methods to extract value from data, and seldom to a particular size of data set.

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.
Thanks,
Yves

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.

Hey,
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.
Thanks

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
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.…

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.

HI,
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.

Hi,
couple of years ago, our client developed a "Document Management" system for their own (it has specific business rules).
Currently, they have 10 million documents and 8 TB of information.
They currently have the system running in 2 platforms (both perfomes slow):
1. Windows Environment (Windows Server 2012 R2, MS SQL Server 2012 R2 and IIS)
2. Linux (Red Hat Linux 6, mySQL and Apache)
As you guess, managing this system have become terrible difficult because of 2 main reasons:
1. Displaying 'search results' or 'document reports' (list documents and properties) takes more than 30 minutes (in employee's computers).
2. To backup they have to do it in serveral steps (and the night is not enogh to make a full backup) (in employee's computers)
So, they have requested to us to improve their system, we are developers.
Also, they have request to us to propose a new platform for managing the new improved Document Management system.
We have done our research in google, but we are not satisfied on what seams to be the new platform so I would like to receive tour recommendations or suggestions about it.
What we initially think is that using the folloiwing should do the work just fine:
- Amazon Elastic (filesystem)
- Amazon DinamoDB (database)
- Apache Hadoop (web server)
- php/laravel (programming)
Your comments are very welcomed.
Thanks a lot.

Hoping to get some opinions.
Plain and simple. I would say 90% of our data stored on the network are PST files created from Outlook. Now when I say 90%, I am talking about hundreds and hundreds of GB, maybe even a TB of data that consists of purely PST files.
What do other companies do to combat people "needing" to save 10 years of email history? I know one of my options is buy more storage, but want to know what other options are out there, or what other people are doing.

I've loaded several months of data to Hive using SAS. I have confirmed that everything loaded successfully and can query the data with no issues.
However, when I move to using an Impala editor (local here Hue/Hadoop) and refresh/update the tables, I get an error when running the following query: SELECT * from data_table LIMIT 1000.
The error is:
Your query has the following error(s):
IllegalStateException: null
Seems that it cant see the table.
Any ideas?

I've been searching for non javascript based charts/graphs to display mysql data. We currently use nvd3 but that is becoming a problem when trying to integrate our software with other products.
I need at least 5 or 6 leads showing the possibilities of creating nice looking charts/graphs to represent mysql based data without needing js behind it, at all. Obviously, we'll have to build the intermediate between the charts/graphs and mysql but first trying to find if there are any such solutions.
I've come across a few html5 things but nothing that is really definitive and truly usable today. I'm looking for any and all alternatives to using JS which can show nice charts/graphs.

Choosing an appropriate provider for your company’s email security can be difficult as email security is a key element in the overall security of a business. A company’s email is an open door for malicious hackers who can potentially drive your business into the ground with one rogue email. There are a few options with regards to a solution but it all depends on picking the right fit for your business. This blog post is dedicated to the options businesses face when choosing their email security.
Generally, the most popular choice for a company are appliance or software solutions. These appliances are great for focusing on certain aspects of email security such as data privacy and spam and virus protection. This option is also easy to install and not very expensive. However, these software solutions require a lot of  "hands on" updates which do not come with the benefits of realtime threat intelligence or the big data analysis that can be performed across the entire network of a cloud provider and can be quite slow to update. These appliances operate by themselves and require occasional attention from the beholder of the software.
Another option businesses have are hosted email security services where the provider is simply hosting an appliance or application to take some management out of the customer’s hands. This option would be considered appealing as the customer …

Hi, I am trying to use something similar to a vlookup in dax and am not able to get it working..
I've attached an example workbook.
In table "Sheet1" I have got a column named "BucketID" which is generated from a formula (from dates being completed or not --- giving me a string of 1's and 0's...) -- I am trying to take that string of numbers, and look it up from table "BucketID" --- by looking up the tableID and then providing the corresponding text.... (this output/formula will be in column "Bucket"
can anyone help me?

I am try to migrate SQL server data to Google big query server my data size of table is 285 GB. how to migarte it.
I have a couple of tables in a database that are using the LONG data type. It's a horrible data type and we need to get rid of it. The question is what do I replace it with? I've narrowed it down to LOB, BLOB, or CLOB but the differences between those seem subtle and I can't quite figure out which is the best choice and why. Some of the LONG fields are storing bitmap image data. Others are storing HTML markup text. I'm OK with using a different data type for each of those. I just need to get rid of the LONG.
