 What's the best unbiased estimator for a series random variables?3 AnswersI guess it is just a Gaussian distribution (Normal dist.). Since it has the smallest uncertainty (from quantum point of view) or variance.I guess it is just a Gaussian distribution (Normal dist.), since it has the smallest uncertainty (from quantum point of view) or variance.It is the OLS estimator (with Gauss-Markov approximations and normality), by Fisher's theorem on Maximum Likelihood Estimators.

 What is a JavaScript callback function?4 Answers5 vote down star 4 I understand passing in a function to another function as a callback and having it execute, but I'm not understanding the best implementation to do that. I'm looking for a very basic example, like this: var myCallBackExample = { myFirstFunction : function( param1, param2, callback ) { // Do something with param1 and param2. if ( arguments.length == 3 ) { // Execute callback function. // What is the "best" way to do this? } }, mySecondFunction : function() { myFirstFunction( false, true, function() { // When this anonymous function is called, execute it. }); } }; In myFirstFunction, if I do return new callback(), then it works and executes the anonymous function, but that doesn't seem like the correct approach to me.I don't think Bloomberg is a very good company. I am an excellent web developer and have gotten multiple offers from other companies with big names, but was rejected by Bloomberg. They are too demanding during the job interview and it becomes a game of how well you can interview as opposed to how talented an employee you are and how much you can contribute to the growth of the company.A callback function is a piece of JavaScript code that executes after the main function that the callback is attached to executes successfully.Show More Responsesudaykanth, I would say that a .forEach() would be the most common and most basic use of a callback function. I'm just writing this to help anyone that might have a hard time thinking up a quick example if the come across this question themselves. Example: var numArray = [ 1, 2, 3 ] ; numArray.forEach( function( i ) { console.log( arr[ i - 1 ] ) } ) ; // logs out // 1 // 2 // 3

 What is the difference between RAID 0 & RAID 5?2 AnswersIt should a simple question if you have worked with computers & HDDs. RAID 0 - Block striping (req. 2 HDDs) and no mirroring or parity RAID 5 - Block striping with 1 dedicated parity drive (req. 3 HDDs)To expand on the previous answer, RAID 0 improves HDD performance dramaticaly, but since there is no mirroring if one drive dies data is lost. RAID 0 should never be used on a system with critical data. In RAID 5, performance is slower, but it allows for the failure of a HDD with no loss of data. Consider instead, RAID 10. It requires a minimum of four HDD's, but provides an increase in performance with redundancy.

 25 horses in a race. 5 horses can run as a group. what's the minimum # of runs required to find the fastest horse.2 AnswersI think 5. Split the horses into 5 groups of 5 then compare the time of the winners of each group. If time comparison is not allowed, then I'd say 6 races i.e. get all the winners to run one last race.Here is a different version of the problem but the answer is here - http://www.programmerinterview.com/index.php/puzzles/25-horses-3-fastest-5-races-puzzle/

 How do you handle irate clients that are having technical trobules and need to work immediately.3 AnswersRefrain from using technical jargon when explaining technical problems and solutions to clients and speak confidently.Approach the situation with 'we' working on the issue. Know that your are there to help solve this and act towards that, being calm and accurate towards solution. Even if the solution is that you will have to find out more and have to return to solve this issue.Ask for the ip address, then ask if it is an on or near-air emergency. Ask for the symptoms and if others are experiencing the same problem. If no one else is then have them jump on another pc if possible/feasible. Remote into the pc or tx the ip to the relevant trouble-shooter.

 How would you scale access to a system like Twitter2 AnswersThere's probably no real correct answer, though the solutions go from common to esoteric in a pretty normal progression: caching, shared-cache like memcache, optimize usage, prefetch, then get creative. This is more about testing reasoning and how far you'll go to solve a problem.I was thinking geographically distributed servers.
