Some prominent outstanding unsolved problems (as well as some which are not necessarily so well known) include 1. The Goldbach conjecture 2. The Riemann hypothesis 3. The conjecture that there exists a Hadamard matrix for every positive multiple of 4. 4. The twin prime conjecture (i.e., the conjecture that there are an infinite number of twin primes 5.

I ntro- After walking a long distance through the forests of Neopia, you somehow stumble upon a small oasis. A trickling stream flows into a shallow pond. Pine trees dot the landscape. "What a beautiful place," you exclaim to yourself. You explore it some, and eventually find a small cave. You enter it to find refuge for your sore limbs. Just as you drift off to sleep, a small furry object pounces on your stomach with a thud. "HI! MY NAME'S TZEUK! WHAT'S YOUR'S?!" the furball happily yelps. "Eh, guest," you respond, rubbing your aching stomach. "Well, this is me and my daddy's cave. He's real nice. You'll like him," he barks. "Wait. You mean we're not alone?" you ask. At that instant, you feel a drop of saliva fall upon your forehead. You look up nervously to see who'd made it. A dark figure hovers over you. May I help you?" it growls.

Using my hand propane torch and some vinyl, I've formed winglets. Since I have to drill visible holes to mount them, I thought I'd try to get some actual data before I start drilling holes willy-nilly. Bumpy paint: I cover a lot of air shows. In the mid '80s, I was able to get up close and personal with a MIG-29, the Russian F-15 clone. Now, these things can go mach 2 but the Russkies had a problem. They can't build a quality aircraft skin to save their lives. So they came up with a unique approach to allow the plane to slip through the air. Bumpy paint. A urethane coating that looks like it has large grains of sand in it was applied before the paint to create a "zone" of separation between the poor fitting panels and the air stream. I was able to have a conversation with the designer who was touring with the aircraft(s) around the United States who was somewhat forthcoming with the information after being plied with some compliments about the MIGs. Photos of MIG attached; note bullet holes in tail. Just a thought.

33. What About Build A Delphi Challenges (in The Spirit Of Fastcode) In the spirit of http//en.wikipedia.org/wiki/Categoryunsolved_problems What kind of challenges are good proposols? http://coding.derkeiler.com/Archive/Delphi/borland.public.delphi.non-technical/2

What about build a Delphi challenges (in the spirit of fastcode) From Date : Thu, 24 Aug 2006 15:33:41 -0500 I'm thinking in start a kind of micro-open source task as challenges, where we start to see creative solutions using delphi. The idea is start to asking us question about the current state of Delphi programming, and how provide coding solutions that are: - More easy to grasp - More flexible - More resource efficient - More testable - etc... and be possible using the current available version of Delphi and capabilities of the lenguage. The idea is condense best practiques or provide more creative solutions for common problems. For example, in threads below some tals about a interesting threading idea. Multi-threading is a concept that is hard to grasp and I don't see a elegant solution made for Delphi... Other thread I start ask about if map/reduce was possible in Delphi. Others ask about generic support or templating in the language. Others ask about best way to archive some calculus and stuff that we found somebody know but with the time the solution and more important, why the solution is importan is lost. Also, a lot of us know other languages and APIs apart of Delphi/VCL and know some elegant concepts that can be applied in Delphi, but apart from some "gurus" are not used by the community at large.
