Anyone cleared Snowflake's SnowPro Certification? I need help with and information about what did you do in order to prepare for this certification. I appreciate your information.
Thank you,
Prashanth.
Snowflake did officially launch the SnowPro Core Certification publicly on Tuesday, October 29th.
To view more information about the SnowPro Core Certification, you can navigate to https://community.snowflake.com/s/snowprocertifications.
No. They dont have transparent process for certification.
First, They have only online proctoring exam, they wont even give option to choose test center on your own.
But when you start the online exam by agreeing to all their conditions (arranging external usb camera, high speed internet etc) they will suspend or stop it by giving some silly reason and tell you to choose test centre by paying $100 more.
Later when you question back they will edit the requirement document itself and tell you are not meeting the requirements. (PFA sample of their requirement change)
Funny thing is they dont even know where is their Server.
It is one of the rubbish process I have seen, Please dont take up this certification and get trapped like me.
Portland OR is mentioned
Phoenix Arizona is mentioned later

What is the difference between MuninAlert and NagiosAlert? Does NagiosAlert has more features for Alert and is better than MuninAlert ? If so, kindly explain the NagiosAlert advantages over 'MuninAlert'!
Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work.
Nagios is a monitoring (alerting) tool. Munin could be a replacenment of Cacti. Nagios tell us in real time if something is wrong: like web server down, db load average, etc.
Using munin you can see the trends and the history about why that happenend.
Nagios will alert you (via email or SMS) when something is down and needs attention NOW.
Munin is for resource usage over time, and useful for things like: Varnish is not caching as much since so and so date, what did we change to cause that? Or, we now have increased CPU usage. Why is that? It allows you to compare day, week, month and past year. Nagios does not provide that, just alerts when thresholds are crossed.
But use both..

could anyone help me answer this question:
Describe transactions and explain the main principles.
I think this link might be helpful
http://www.tutorialspoint.com/sqlite/sqlite_transactions.htm
There are many reasons for them. Among other reasons, transactions protect the integrity of your database data by allowing you to decide at the end of a session whether you want to commit the changes or revert back to the state the database was before you started making changes. Cases where you would want to revert back might be cases where an error occurs in your program while.
For example, if you are building a program for a bank that handles money transfers, you will likely make a query to update the balance in the customer's first account to be what it was minus the transfer amount. However, if you run into an error when attempting to update the second account, it would be nice to just abandon all the changes made and return both tables to their original state.
I hope the link helps.

I cannot find way how to see all packages of given author on http://pub.dartlang.org
For example, if I want see all packages of caolan on https://www.npmjs.org I can click on the author link and go to author page https://www.npmjs.org/~caolan.
As far as I know, packages on http://pub.dartlang.org also has their own authors.
That is, they has rightful owners.
For some reason I could not find a way to get an overall picture about the packages relatively of their authors.
Is this possible?
If not possible then why?
P.S.
I am amazed at all the paucity of services provided to http://pub.dartlang.org.
The impression is that nobody does this because they simply do not care about it.
Maybe there is an argument in favor of the fact that I'm wrong?
I do not think that requires huge investments.
Pub site doesn't have such feature for now.
However the sources of http://pub.dartlang.org are available on https://github.com/dart-lang/pub-dartlang/ . You can help to improve the service by submitting Pull-Requests.
You can alternatively use the json output of http://pub.dartlang.org/packages.json and http://pub.dartlang.org/packages/xxx.json to achieve what you want. I made that and you can see a raw result at http://a14n.github.io/pub-infos/packages-by-uploader.html. The collected json datas are available at http://a14n.github.io/pub-infos/datas.json. (The sources: https://github.com/a14n/pub-infos )
It is not possible yet. There have been some mentions of improving the pub site. However, nothing has happened as of yet.

I am looking to create an application for exchange rate of foreign currencies and need backend for the same. While searching for the same, i came across:
http://rate-exchange.appspot.com
http://rate-exchange.appspot.com/currency?from=USD&to=EUR&q=1 //working demo
I also find the github source for this GAE project at:
https://github.com/hippasus/ExchangeRates
Now the question I have how should I proceed. Shall I use this already deployed project named http://rate-exchange.appspot.com or deploy my own version. If I should deploy my own version then what will be steps.
Thanks in advance
Generally try to use existing code with permission and visibly give credit to avoid plagiarism. Developers who repeat work already done by others learn from the experience but risk wasting time unnecessarily. You learn from others by studying their code anyway.
You may after some experience with the other project think of ways to improve it. Liaise on Github with the original author about constructive collaboration. Sharing code is what makes free and open source software great.

i am currently undergoing the branding of a place that is in the outskirts of a major city. the situation at hand is that the place is unknown and not easy to get around, so my associates and i have planned to develop a gps application with specifics eg safari lodges, conference venues of this area and make it possible for people to download it onto their smartphones (nokia,iphone and black berry) and be able to navigate their way around.
the issue is how much would it cost to develop such an application and run it?
need an answer ASAP. thanks a mil.
The answer to this question could be 1000$, but it could be 100.000$ as well. There are so many details to a project like this that must be taken into account that it is almost impossible to answer your question more precisely.
To give an example - consider details like (but not only):
who will supply the necessary content
does the content need to be updated on a regular basis -> CMS
should the app navigate the user around in turn-by-turn style or should it be more like an interactive map
These three details alone would make a huge difference. So, the best thing you can do is contact a company or a freelance developer, brief him precisely on the matter and see how much it'll cost you.
