Also, be aware that many non-expert attempts to develop compression algorithms turn out to be flawed. However, it sounds like you've developed a compression pre-processor specifically targeting JSON-like structures, which seems like a much more plausible accomplishment than a non-expert developing a brand new general-purpose compression algorithm that can beat LZW.
All that said, if I were considering hiring you I would be much more interested in your ability to rigorously analyze the strengths and limitations of your algorithm (rather than the algorithm itself). Plus, without that rigorous analysis it makes it much more difficult for me to judge the quality of your algorithm.
Strangely enough, this was the exact dilemma that Clarissa faced in in Episode 29 of Clarissa Explains it All, "Poetic Justice," in which she developed a program that generated poetry. When her program's poetry won the school's contest, she decided to publicly relinquish her award to her computer. http://en.wikipedia.org/wiki/List_of_Clarissa_Explains_It_Al...
Node.js and client-side JavaScript should treat security issues differently because they face different risks. E.g. A DoS against client-side Javascript is not a big deal (because it might slow down a single browser, or even just a single tab within a browser). However, on the server side, a DoS could take down an entire service which is much more significant.
Thus you could say that V8 is "secure" on the client side but "insecure" on the server side because of the different risk assessments. It is poor security practice to take software designed for one security environment and assume it will be secure in other environments. If Node.js wants to have a secure system they will need to take these security issues into consideration and harden their system appropriately.
(1) The vulnerability report exists in the "shadowy ground between the reports that are clearly crackpot and the reports which are clear enough that you can evaluate them with confidence" (from the blog)
(2) "Oh, we recognized it immediately. But it was so obviously wrong that we began to fear that we were missing something." (from the comments)
(3) "this entire investigation took five days to complete, plus another day or two to complete the necessary paperwork." (from the blog)
This blog post paints a picture that Raymond's organization does a bad job triaging reports and prioritizing investigations. It's a waste of five days to analyze an "obviously wrong" vuln report, just on the off chance that there is something deeper. How about spending five minutes emailing the author of the vuln report, explaining why it doesn't appear to be a vulnerability, then asking if there is anything deeper?
It's also crazy to spend a day or two filling out TPS reports on a crank vulnerability alert.
If an organization takes security seriously then it should spend increasing amounts of time on increasingly plausible vulnerability reports.
The article is so close to a direct Feynman quote that it makes me wonder if the author was subconsciously plagiarizing Feynman. Normally, I wouldn't mind (subconscious plagiarism is everywhere). But in an article about intellectual honesty I would expect the author to "bend over backwards" to identify and declare potential sources of plagiarism. ;-)
Posting articles such as this one is very helpful because it pushes useful esoteric knowledge into our consciousness. HN is particularly suited because the community's up-votes convince us that our time will be well spent looking into such articles.
