a_d··on A brief history of the peace symbol
Article makes the point that the symbol commonly used for peace, originally was a logo for nuclear disarmament. Well, the common-use meaning is not that far apart :) A nuke-free Earth would be one of the biggest, if not the biggest contributors to world peace.

(From the tone of the article, I was worried that the symbol originally meant something quite different from what it has come to mean today. But no. Same ballpark.)

a_d··on New Video of F-117s Flying Out of Tonopah Despite Their Fates Being Sealed
You may be right. I just don’t know why the old style pc games died. I just attempted one possible explanation —- For sure there is more to it.

it just seems to me that LucasArts (adventure games like Monkey Island), MicroProse, Sierra, Westwood, Firaxis, Brøderbund etc just died in a span of 10 years and PC games just never got back to their older style.

Wow. Had no idea that Sid Meier was connected to this game. His Railroad Tycoon (esp RT2) is one of the greatest "business simulations" of all time!

>Also, manuals in XX century were great. They were often decent books by themselves, full of information and lore. Somehow, this concept was abandoned around 2000 +/- couple years

Very interesting point. I wonder why did this happen? I believe the manuals/books with backstory/guides that came with the box, added to the engagement with the game. Why did they go away? Seems like a needless regression :)

Sometimes I lament that the entire character of PC games changed as well during the same timeframe, as they become more console-ish/FPS-style, rather than adventure/puzzle/strategy/sim style. But then I remember that probably every generation romanticizes the good old days. Technology advancement explains the shift to FPS (better game engines, graphics cards, leading to more immersive worlds and movie-like narratives + multiplayer is exciting), but doesn’t explain the death of the game “manual/novel/book” :)

>This was far & away one of my most cherished games.

Hmmm...going by this thread, I am really surprised that there are so many of us who like this game. This is quite cool actually! :)

The original manual was about 200 pages! I can’t find it anywhere online. It goes into tons of other things — like the construction of this plane and dogfighting tactics (even though this plane isn’t designed for it) :)

>It was probably the most I read when I was 14

True for me too. I remember that game. Reading the manuals for all the Jane's and Microprose's games, and taking them very seriously, was definitely a childhood highlight.

Btw, I found that GoG has F-117A and the reviews are awesome. I hope these are genuine reviews because they definitely echo my experience :-) Here is the link: https://www.gog.com/game/f117a_nighthawk_stealth_fighter_20

"...it will keep you on the edge of the seat.."

"This game is in the top three of all PC games I have ever played."

Definitely echoes my colored-by-nostalgia-memories :)

Edit: I have a question — what is the best way to play this game on a MacBook? (Without installing windows or Linux)

One of the closest experiences to flying this thing came in 1991, in the form of "F-117A Stealth Fighter" PC game, made by MicroProse. It was a masterpiece for its time in terms of the detailed console one had to learn to fly this. If you never play the game, you should just consider flipping through the incredible manual: http://www.abandonia.com/files/extras/25631_game_extra_1.pdf

The game and the manual had a ton of jargon that one had to learn to play the game, adding to the feeling of being in a real sim :) The section on evasion and defense systems was especially charming (Basically, this game was a dream for a kid who was into PC games and flying sims). The paper version that came with the box explained tons of small details about the plane e.g. how radar absorption paint works (I learned later from a documentary that F-117 had to be repainted after every mission, making maintenance very expensive).

Two highlights of the gameplay were: a) landing on an aircraft carrier and b) learning capabilities of different types of missiles and how to deploy them (i.e. one was forced to read the manual!).

When I hear about F-117, I can't help remember this hidden-gem PC game.

a_d··on Portrait of an Artist as an Old Man: Mel Brooks in His 90s
Yes. Roast beef sandwiches, Potato salad and soup :)
a_d··on Portrait of an Artist as an Old Man: Mel Brooks in His 90s
Mel Brooks features in two Joseph Heller (of Catch-22 fame) books: No laughing matter and From Coney Island to here. It is amazing to read about how Mario Puzo (of The Godfather), Mel Brooks, Joseph Heller, Speed Vogel spent their evenings together, playing cards, eating dinner, watching TV and just ‘shooting some shit’ as friend do. The passages in the book reminded me of impressionist painters gathered in a Parisian cafe talking about where to get cheap turpentine (as depicted in the book ‘Lust for life’). Worth a read! There is also an article where two old friends (Brooks and Heller) meet again:https://www.washingtonpost.com/archive/entertainment/books/1...

Also, in one of the brilliant episodes of Jerry Seinfeld’s Comedians in Cars Getting Coffee, he pays a visit to Mel Brooks and Carl Reiner (with Chinese Take-out food) — I highly recommend watching that to get a glimpse of sharp incisive wit in full action at age 90!

a_d··on Implementing Neural Turing Machines
“how the memory contents of a NTM are initialized may be a defining factor in the success of a NTM implementation”

Does it mean that one can expect better explainability in the future from these models?

a_d··on The secret call to Andy Grove that may have helped Apple buy NeXT
I am amazed how much truth there is in these paragraphs, esp for B2B cos.
a_d··on What if people were paid for their data?
Any suggestions on good sources: Where can I learn more about it? (Thanks for the comment. Very curious to learn more.)
a_d··on Unauthorized Access to or Acquisition of Chili’s Grill and Bar Guest Data
This is a very easy list of things they want you to do:

1. Contact the nationwide credit-reporting agencies as soon as possible to 2. Add fraud alert 3. Place a “security freeze” on your credit account: with experian, trans union, equifax 4. Watch Bills, Statements and Mailing Lists 5. Contact the Federal Trade Commission, if you suspect or know that you are the victim of identity theft (report to their fraud dept) 6. If you believe you are a victim of identity theft you should immediately report same to law enforcement and/or your state attorney general

Serious question: given that this happens quite frequently (with with Equifax! One of the places where you must go to report this stuff), are there any services that do some of the above steps automatically on your behalf?

Also, this was posted here a while ago: some excellent advice —> https://www.kalzumeus.com/2017/09/09/identity-theft-credit-r...

a_d··on What if people were paid for their data?
If someone were to figure out the exact mechanics of this, then this could become universal basic income.

I have thought a lot about what trapped intangible value all of us have, such that ‘if’ there was a market for it, we could get paid. Our personal data, with opt-in volunteering, is certainly at the top of the list. The other potential personal markets that have very similar characteristics (to personal data), but don’t exist are:

1) Home equity: Americans have $6.2T in home equity that could be “sold”

2) Driving data: get paid for carrying free sensors so that one helps map the world, so we get to self driving sooner in more cities

3) Opinions: large scale polling for everything, from movie trailers to startup landing pages to new products/ads — everything

4) Fact checking: crowd sourced journalism; often Reddit crowds figure out the truth/source faster than pro journalists; there ought to be a market for “if I know something, Eg some insider info, I could improve on the state of public truth”

5) Goodwill: one of the most amazing things I stumbled upon was www.reddit.com/r/borrow; people ask for money and strangers give money; I would never have predicted this to exist. I believe goodwill and benevolence is one of the largest untapped markets.

There are probably several other (and better) examples: point is that royaltiess/annuities from such markets could be part of UBI in the future.

a_d··on What to do with too much advice
There a lot of great points on this thread. We need more distinction between contextual and non-contextual advice. If one is ‘at the board’ working through a problem — then a hint or solution, moves the problem forward. On the other hand, if one is just ‘leisurely browsing advice listicles’ without being at the board, facing the problem, then most likely you are just ingesting dopamine-flavored noise.

Advice without context from anyone — whether it is PG, pmarca or Richard Feynman or {_your_fav_successful_survivor_} - would be useless, unless you are working/thinking about the problem that they are giving solutions for. Help only works if you are looking for something. Also sometimes it is good to just enjoy problem-solving and figuring things out. We are too quick to look for advice — and I get why: because no one wants to “reinvent the wheel”; There are too many standardized administrative things with startups that can be just solved by looking up advice; no problem with that; but sometimes it is worth struggling through a problem even though geniuses like PG and pmarca can give a solution quickly.

Abundant capital has led to too many VCs with too many blog posts looking to differentiate with their advice, under the guise of differentiation, content marketing, “proprietary deal flow” etc. If content is “bait” then you are at the bad end of the line.

When faced with a problem, find someone who can help — All other times, just do the work and enjoy problems :-)

(Did I just give advice? Can’t tell)

a_d··on Interview with Sam Altman from the High Growth Handbook
Oh hey Elad! You are welcome. You should know that everyone I know who has interacted with you, speaks incredibly highly of your wisdom —- I am amazed by the breadth you cover —- as these people work on things ranging from Longevity to SaaS to Crypto! I have always admired your wide ranging interests and sharp wisdom (We have never met, but have been an indirect beneficiary of your wisdom — we have a number of common folks). Your personal investing track record is enviable too! Any insights on how you pick who/what to bet on? (Is there a self interview in the book ? :-))
a_d··on Interview with Sam Altman from the High Growth Handbook
I consider sama to be an extraordinary investor and thinker (I know this is the most consensus thing one could say on HN). The personal bets on Boom, Helion Energy, Cruise and many others are really phenomenal (even the re-bet on Reddit) -- not just for being early/contrarian for their time, but also necessary for the world for these companies to succeed.

The highlights of this interview imo are the following pieces of advice:

1) get a coach sooner than later

2) always keep revisiting what is urgent vs important and keep prioritizing; if in 'war-mode' then users, team, revenue above all else; ignore things that don't amount to much (potential candidates: investor updates, press, conferences etc -- they are not more valuable than users)

3) don't get too far away from the product (some things cannot be delegated early on)

4) "boards hate surprises...and boards hate feeling like you’re trying to hide bad news". Be open. Ask for help.

Really great points.

I feel that the point about the role of the CEO in a downturn is under-explored in this interview (felt rushed). This is rich territory (and relevant). The discussion about specific examples of things that don't merit CEO time veers into 'made-up territory' quickly and doesn't feel relevant -- e.g. some "[CEOs] then stop going to the executive team meeting (that’s a very bad idea)" -- I don't see as many companies as these two, but no CEO stops going to an executive team meeting (infact, bad CEOs go to too many of those! as they enjoy 'playing CEO' :)). If a CEO stops going to an executive team meeting, that is quite counter-intuitive and interesting in many respects in of itself (e.g. there is a fire; CEO doesn't want to be CEO etc) :-) I feel Elad should have pressed more as an interviewer rather than rushing to the next point.

Overall, always good to hear sama's views -- he is an incredibly important investor of our age (my prediction). And Elad thanks for working on this book. For a few $$ everyone can get this wisdom -- you did a great service for entrepreneurs. Congrats on the launch.

a_d··on Health Insurers Are Vacuuming Up Details About Customers
Whenever someone says that AI and IoT would automate insurance underwriting, I start to fret — because it very quickly starts to imply more and more data collection. This is like pre-crime but for your health. Meaning, you start paying high premiums right away because later in life you might be at a high risk for a specific condition. (I know this already happens for smoking, but that is declared on a form — not by a company sending a drone to spy on you)

Since this is a startup forum — I believe health insurance to be so dark and morbid (with things like companies haggling with living relatives about ventilator care) — there is got to be a better way! (I realize this is more of a lament than a constructive suggestion)

a_d··on Coinbase reportedly gets approval from US regulators for tokenized securities
Tokenized securities are like a record of ownership, written and maintained on a ledger. They are like normal shares, governed by securities laws of the land. They could have dividends and could trade between two parties. Not sure what exactly you are asking?
a_d··on Coinbase reportedly gets approval from US regulators for tokenized securities
I can also imagine startup equity being tokenized. Where an exchange like Coinbase acts like SecondMarket (now called Nasdaq Private Market). This might be a great way for early employees and founders to get liquidity before the company IPOs. It would change the startup game completely. A lot of things to look forward to here.
a_d··on Coinbase reportedly gets approval from US regulators for tokenized securities
Tokenized securities are private securities that comply with securities laws using Reg D, specifically Rule 506(c). In some cases they are Reg A+ (that come with JOBS act provisions used for crowdfunding). They are very important for the ecosystem for two reasons:

1) because ICOs are very important way of fundraising and they need to become compliant

2) they make illiquid assets like private real estate RIETs more liquid

Since KYC/AML is enforced and investor accreditation is key to buying these securities, this will reduce scam and legitimize ICOs and security tokens overall.

I can’t wait to see all the interesting possibilities with making illiquid assets more liquid using tokens to represent shares. This is an exciting development. Congrats to Coinbase.

a_d··on Ask HN: Favorite note-taking software?
Products from www.literatureandlatte.com deserve a mention on this list - they are called Scrivener and Scapple. I realize they might not be for everyone (both are paid), but I find them delightful.
a_d··on Ask HN: 2018 Summer Reading List?
I have a sort of meta-question, Specifically about non-fiction work: if one gets the central idea contained in the book (say, from a blog or Podcasts or YouTube video of author explaining the ideas) - Is it still useful to read the entire book?

If a book is fundamentally about “ideas” — aren’t there more efficient ways available today (that were not pre-internet) to learn those ideas more quickly?

As an example: There is a Dave Rubin podcast where Jordan Peterson lays out the 12 Rules of Life very clearly and concisely. If one knows the rules and understands them, is it still necessary/important to read the book?

I wonder, just how much “reading the entire non-fiction book” is increasingly now an archaic way to ingest new ideas?

a_d··on Napoleon as Organizational Designer (2009) [pdf]
Adding more “micro army” pods would exponentially increase the coordination costs / communication overhead. If communication is the main challenge then decentralizing power would lead to more org ineffectiveness (centralized/command-control structures would be better).

Anyway, as I commented earlier: I think the authors miss the central innovation that enabled org innovation — which is all the tech Napoleon developed around messaging!

a_d··on New species of flying penguin discovered on 1km sand strip island in New Zealand
“Although the island is predator free, and the birds are safe from predation, there are still large threats facing this small population. Sand dunes are particularly vulnerable to erosion and turbulent seas have cut away much of their habitat. Climate change and storm surges also threaten the species’ survival.”

I wonder why the population isn’t thriving. Elsewhere in the article they are referred to as a “threatened population”. Not sure what’s the threat.

Anyway, interesting study.

a_d··on Napoleon as Organizational Designer (2009) [pdf]
The authors don’t do enough to sell the basic org design framework well. Then they use this (somewhat weak) framework to analyze Napolean’s org design. Makes it a v confusing paper. (Also, the hero worship throughout the paper makes it seem like everything Neapolean did, fits their beautiful theory. Too much fitting going on :))

“Strategy should utilize the five basic principles of organizational design: division of labor, unity of command, authority and responsibility, spans of control, and contingency factors.”

What!? No one designs orgs like this. Orgs are designed around:

A) “Axis of Excellence” (Eg if you want functional excellence in your org - ie the best salesperson to lead sales, the best marketer to lead marketing - then you organize around functions likes Sales, Marketing, Engineeing etc). OR,

B) “Max{Collaborative Output} and Min{Communication Overhead}” needs - Eg if people across functions need to collaborate closely to produce a business result then one create those units accordingly - they could be line of business units ( eg textile: spinning, packaging etc) or geo-based units.

Looking at the framework they use makes me wonder what useless theories are being taught in MBA schools :-)

The most interesting bit in the paper is about messaging. Seems like Napoleon invented HipChat/Slack of his day to make his orgs work more smoothly. That was quite cool!

“Napoleon utilized the existing technology of the Chappe’s semaphore telegraph to improve his message traffic. He maximized its potential by constructing towers across Europe creating a communications web that would cover his expanding empire (Elting, 1988). When messages were too long or not as important to use Chappe’s telegraph, Napoleon relied on the European postal system. He made improvements by creating an express courier service. Messages were carried in a lock box with a logbook that showed the date and time of arrivals and departures of couriers to each post house”

a_d··on Why Envy Might Be Good for Us
“Namibian hunter-gatherers deride those who stand out.“

It depends on what the goal is. If the goal is to produce abnormal outsized returns: they likely come from standing out. Being somewhat contrarian against the tribe helps with finding new pastures - infact it might be the only way.

If the goal is to maximize egalitarianism, which is a worth-while goal, then having mimetic/conforming attitudes would be a virtue. Envy is a by-product of our mimetic desires.

a_d··on The Benefits of Thinking Small (2010)
Such a great comment. I will use this hamburger example from now on to make the point I was trying to make! :)
a_d··on As Bitcoin declines, Coinbase’s app is dropping in popularity
Coinbase’s app is an investment/trading app. In a full-blown bear market, it is natural for this to happen.
