inboulder | 1 year ago | on: Show HN: FastGraphRAG – Better RAG using good old PageRank

PageRank for better centrality seems neat, but it still doesn't address the probably unsolvable flaw with RAG, the reason why RAG basically can't work. All RAG DBs under-perform expectations because RAG fundamentally can't find relationships between words necessary to find the information the user cares about. Weird right, isn't this what the 'attention' mechanism is supposed to be good for? It just isn't good enough.

Example: Say you're searching an article and you want to know what occupation a mentioned person has, let's say the person 'Sharon,' is mentioned to have attended several physical chemistry conferences but her occupation is never explicitly mentioned. There's a very good chance every single rag approach will fail to return correct results, will fail to make this connection between 'occupation' attends conference, type of conference and infers 'chemist'. I could go on, but this sort of error is pervasive along all types of information when trying to retrieve with RAG. In the end, solutions like the above seem to just sort of reinvent other query methods, SQL, pagerank etc, with extra steps... there's little point in vectorization at that point...

inboulder | 15 years ago | on: Study: If aliens exist, they probably want to destroy us

I think this article makes a fantastically gross error, the conclusion is fine, however the authors gloss over the fact that any space-faring life has a high probability of being machine-intelligence, not squishy biological life which 'evolved in the same manner as on earth'. (note, this is already the trend with our space exploration)

inboulder | 15 years ago | on: Study: If aliens exist, they probably want to destroy us

You're neglecting many reasons extra terrestrial life may pose a threat.

The most obvious is they may want our planet, they want to live here, and if they've managed to travel across the vast void of space, wiping out humanity probably won't be particularly challenging for them.

Also, your second point is invalid, territorial reasons are not void. We may pose no threat now, however a technologically superior civilization may conclude we pose a future threat, and so wipe us out now before we can become one.

Also, the old 'dangerous biology from somewhere else!' is almost entirely null and void, organisms are adapted to their environment, they usually pose negligible risk to any other environment already inhabited by biological organisms. This is why, for instance we don't treat organisms from thermal vents as 'oh noes, biohazard material'.

"Cheezburger has been a profitable business since inception. We have been profitable every single quarter, and never had a quarter with negative cash flows. "

Oh come on now, how could you have negative cash flow? Your whole business model is based around publishing content on the web you didn't create, (and 99% of the time probably don't even own the rights to), this is not exactly an expensive business to run.

>> For example, Java, can you tell me the difference between volatile and synchronized as it regards the memory model without looking it up? What's a happens-before relationship and how is it relevant to those keywords? What's the transient modifier do?

>I didn't claim to be a Java guru. Very few Java programmers actually need to know the answers to those questions in day-to-day programming; I could probably (if asked to, which I'm not, thankfully) write thousands or tens of thousands of lines of Java without ever needing to know the answer to those.

You're wrong, and this proves the point. This isn't 'guru' level, the workings of volatile and synchronized is even on the basic SCJP test. This may not come up in your domain, but if the project deals with threading, an experienced dev will be more productive than you right off the bat, after two weeks, and probably after a year.

In fact, threading is pretty tricky, so it's likely you will be counter-productive to the team until you've made all the Java threading mistakes you need to make in order to understand why your code is bad. And, you might never know your code is bad unless a domain experienced Java dev explains it to you.

Domain experience matters.

"Ernest Hemingway than Kurt Vonnegut"

I think you're trying to make a 'smart' reference but are confused. Overall, Vonnegut was generally at least as, or more concise; there is an entire page in _For Whom the Bell Tolls_ dwelling on the sweat on someone's brow.

inboulder | 15 years ago | on: Why do the Japanese draw themselves as white?

This doesn't explain or even address why the Japanese favor 'large round eyed' actors in ads for beauty products, why darker skinned Japanese women are not featured on TV, and why the current depictions of beauty in Japan eschew many traits common to classical Japanese portrayals of beauty.

It is glaringly obvious that European ideals of beauty have enormously affected the Japanese aesthetic, especially including anime; almost any Japanese person you meet will readily admit to this, to claim otherwise takes willful ignorance.

"Isaac Newton or Emily Dickinson" funny you should have mentioned both of these folks, they both died virgins. The world might have been better, but they never got to experience an important part of being human.

inboulder | 15 years ago | on: Why Reddit's Founder was "Terrified" to Launch New Startup, Hipmunk (YC S10)

"hipmunk" (I really hate domain squatters if this is best URL you guys could find available?) looks good, but I wonder if it's all flash 'agony' and name recognition (hey you got cnn to write an article already, sweet hook up!). As far as I can tell it has a pretty 'info graphic' interface, but doesn't really do the thing that would get me to use it: save money on flights.

Does hipmunk do anything different? It doesn't look like it can tap into sabre, ryan air db, etc, looks like it just scrapes and organizes, nor does it look like it has any fancy back end db of extensive flight info with a smart heuristics engine to predict future prices. So, beyond help those who have trouble visualizing a schedule, I'm not sure how this is any better than farecast et all. Can hipmunk predict if a particular flight's price (not willy nilly flights, I'm looking at you farecast) will go up or down?

inboulder | 15 years ago | on: Ask HN: Best Startup City - Outside the USA?

From growing up in, and visiting London frequently, I don't really agree. London is as, or more expensive than, NYC. Programmers are expensive in London, and in dealing with the British tech culture, they don't seem to have the 'entrepreneurial spirit' I'm used to in the US, it seems less 'young, talented, take on the world attitude' and more about working at satellite offices for IBM etc.

If I was going to pick somewhere in the EU, I'd go for Berlin.

inboulder | 15 years ago | on: On ‘Mad Men,’ The Allure of Messy Lives

Anyone else get bored with it after the first season? I mean, it's an ad agency, there's only so many plot-lines before it just became a soap opera. I also didn't understand how the main character hardly said a word, yet people seemed to think he was interesting, the writing wasn't very sensical.
