The Five Essential Phone-Screen Questions

Stevey's Home Page - The Five Essential Phone-Screen Questions�

Without further ado, here they are: The Five Essential Questions for the first phone-screen with an SDE candidate:

1) Coding. The candidate has to write some simple code, with correct syntax, in C, C++, or Java.
2) OO design. The candidate has to define basic OO concepts, and come up with classes to model a simple problem.
3) Scripting and regexes. The candidate has to describe how to find the phone numbers in 50,000 HTML pages.
4) Data structures. The candidate has to demonstrate basic knowledge of the most common data structures.
5) Bits and bytes. The candidate has to answer simple questions about bits, bytes, and binary numbers.

The FizzBuzz test & programmers ... or not

Coding Horror: Why Can't Programmers.. Program?

Simple test for programming skills:
Write a program that prints the numbers from 1 to 100.
But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz".
For numbers which are multiples of both three and five print "FizzBuzz".

All teachers of programming find that their results display a 'double hump'. It is as if there are two populations: those who can, and those who cannot, each with its own independent bell curve. Almost all research into programming teaching and learning have concentrated on teaching: change the language, change the application area, use an IDE and work on motivation. None of it works, and the double hump persists. We have a test which picks out the population that can program, before the course begins. We can pick apart the double hump. You probably don't believe this, but you will after you hear the talk. We don't know exactly how/why it works, but we have some good theories.

So true. I see this in all my programming subjects!!!

Top hints are:

Tip 1: Cascading style sheets, tables, and XSLT

Tip 2: HTML entities

[ incidentally, to use non-breaking spaces, use #&160; ]

Tip 3: Multiple input documents

Tip 4: XSLT and client-side JavaScript

Tip 5: Automating style sheet creation

You can also do a similar trick using metro (which incidentally is what is actually installed on weblogic 10.3 under the covers :-)

Dunno if you can try it via java se6 built in httpserver (endpoint). Might try it out.

GNS3 - a Cisco network simulator

Woot! A colleague at work suggested the following for practicing your Cisco certifications
Graphical Network Simulator 3

This basically simulates the common hardware used by the following CISCO routers:

Cisco 3600 series (3620, 3640 and 3660), 3700 series (3725, 3745) and 2600 series (2610 to 2650XM, 2691).


The core module is the Dynamips project (http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator)

Dawn of the App Aware Network

Part of my research is looking at moving apps from the core of the network to the edge (or network aware devices).

Web services (and XML-RPC and REST) and Enterprise Service Bus fit this model quite nicely.

XML accelerator Devices such as Cisco AON or Cisco ACE (ex-Reactivity) or IBM Datapower can be used to replace the Web services routing function required by modern distributed applications into the network.


The implication?

This changes the model of application development from a software-architecture centric viewpoint into a services oriented architecture.

And the commoditisation of this will drive costs down for enterprises and will harm revenue for middleware vendors.

The edge is here.
Why not go a step further? How about pushing application processing to the edge of the network?
In my Faculty [Engineering and IT]/School of Computing and Communications, we are developing Mobile Health applications using 'motes' - tiny devices running a pico-net (and a mutant version of Java)

Ditto with Post2Blog

The issue with free code is that is rarely is updated when the underlying API’s change.
