As far I know there is current shortage in the new GPU market. High prices has nothing to do with tariff.

Can we stop posting twitter treats?

See a lot of criticism here. For a math new grad who wants to break in software development, what similar guide would HN recommend? I'm specially interested in backed.

I prefer the guide to be extensive like this one because it give me a sense of what I know and don't know.

Do you have any sources?

Thank you Lex. I think your podcast are the most interesting in the internet. But...

Readings books is awesome because you are getting the condensed knowledge that someone have spend maybe decades of their lives to compile. When I listen to a podcast the same applies to a lesser extend. The problem is Lex does not ask interesting questions. He dwells into philosophical and common questions i.e "What is the meaning of life", "is math invented or discovered". This questions are interesting but are not in the guest field of expertise which in turn causes them to give a generic response. This devalues the quality of the podcast.

I believe A* should always give the minimum path as long the heuristic is optimistic. It will become a greedy search if the heuristic is pessimistic. If the heuristic is "perfect" i.e heuristic(x to y) = min_cost(x to y) the the search will be optimal (i.e no nodes that do not belong with the path will be explored)

Yep after playing around with it for a bit it didn't give a minimum path. I believe something is wrong with the heuristic you are using.

Edit: You can prove A* will give a min path as long as: heuristic(x to y) <= min_cost(x to y). Problem seems to be here https://github.com/ssaric/algoviz/blob/master/src/util/GridN... I think it should be a matter of removing "times 100"

The other day I brought a large furniture and no other option but to transported with the trunk of my car open. The car has "protective" beep system whenever the car drives with the trunk open or with seabelt off. So my car was beeping the trip...it almost drived me insane.

It is so sad that I can no longer control what my own car does. This is only about to get worse as tech improves.

Heck our phones and computers are probably sending thousand of telemetric information right now and we don't know or control. It just a matter of time until cars do that to, and we cant not longer control who to utilize our own cars.

Yeah, when threadripper came out I believe it offered the same performance as intel I9 for about half the price. Why did AMD choose such aggressive pricing? Because they have the desire to grow. If Intel and AMD had the same market it would not make sense to put out a product for half the price as your competitor. So if Intel and AMD had the same share, we would probably still paying 1000+ dollars for intels I9.

I don't think that's the heart of the question. My question is is better for innovation if two companies have equal market share or if one has a smaller market share? I trying to argue that it is better if one company has a smaller market share.

Case 1: Netflix. Netflix caused innovation in the movie rental industry. But when Netflix first began it had much smaller market share compared to blockbuster. Would Netflix innovate again? Sure, but I doubt it would do anything revolutionary again. Most likely it would grow stagnant, once the new market stabilizes between hulu, HBO, disney, amazon etc.

Case 2: Apple. Apple was the underdog in early 2000s and that caused then to innovate, while Microsoft had grown stagnant. Today both Apple and Microsoft sort of have similar market shared and they don't really compete with each anymore. Microsoft shifted to cloud, and dropped windows phone. Apple keeps doing what they are doing with marginal upgrades to iphones, and mac. I don't really expected to come up with another "iphone" level innovation any time soon.

Case 3: Amazon. No big company is really trying to compete with amazon this days. I don't see Google or Facebook coming up with own online stores. It just not worth it to compete. While they are a lot of smaller online stores.

Case 4: Automobile industry. Sure they are new car models each year...but it is nothing revolutionary. Simple marginal upgrades over last year model. It was not until an underdog (tesla) tried to gain market share that we have seen any sort of innovation from them.

Most of the innovation today happens at smaller companies, and they eventually either succeed and become the next Apple and Google, fail and go out of business, or they get bough by the big companies.

I think a clearer is example would be with telecom companies. Say A and B, are telecom with equal market share. A, could "compete" in an attempt to gain market share and install a gigabit bandwidth, but this will only cause cause company B to retaliate and instant gigabit bandwidth as well. Therefore the market share and revenue will fluctuate back to equal. But both companies would have lose the money involved in installing the higher bandwidth. Therefore if the market share is equal the best strategy would be "tic for tac" i.e wait until you opponent does something. Which has two equilibrium either constant tic for tact. Or waiting for the opponent does a move.

In the case when one company's market share is smaller than the other it is always better to "invest" or compete.

Yes it oversimplified. Suppose that a = b, i.e both companies has the same market share. Also suppose that when both companies has equal market share their innovations rates are the same, same price etc. The model has two equilibrium both companies compete in which their market share fluctuates around a = b. and we get a sort of predator-pray model[1]. Both companies do not compete their market share stays the same.

What does it means to compete? It could mean many things like not putting lower prices, delaying innovations until competitor has release their own etc.

Consider two company A and B. A has market share 'a' and B has b. n is the total market. Then a + b = n.

A's reward for competing will be n - a = b.

A's risk for competing will be a, (it's remaining market share).

A's will compete as long as the reward is greater than risk.

This will reach an equilibrium at a = b.

From the game theorist point of view I think its better if one company is the underdog. Think about it, if one company is the underdog, one company has a lot to gain by competing, while the other has a lot to lose if they don't compete. Therefore we get competition. Now, the more equal the market share of the companies the grater the risk and less the reward for competition... A better strategy would be not to undercut your competitor and instead divide the market share. Which leads to stagnation.

Do people here think it sound reasonable?

Edit: Mathematically the argument would be as follows:

Consider two company A and B. A has market share 'a' and B has b. n is the total market. Then a + b = n.

A's reward for competing will be n - a = b.

A's risk for competing will be a, (it's remaining market share).

A's will compete as long as the reward is greater than risk.

This will reach an equilibrium at a = b.

I study at FIU... I just don't see the point this bridge. Why would you spend 10+ million dollars on a bridge to cross a street, when the same problem can be solved by a simple crosswalk? We already have one of these bridges... and the majority of people don't bother to use it and simple take the cross walk. It just such a waste of money.

Why do say that Linux will only ever support Level 3? Is there some fundamental limitation?

AmazonPrime video does not delivers HD content in Linux... I tried everything switching browsers, changing User agent, wine, running virtual box. I seems some type of DRM is not implemented yet in Linux. Netflix is the same I think.

I happily pirate content now.

Yep, having used Tinder's paid boots and seeing no results. And then making a new profile with the same photos and bio! and getting results within minutes left me feeling rob and manipulated.

Rewriting one of my earlier comments: I have used Tinder (owned by Match) before and it was one of the must frustrating experiences ever.

First, they do shady things with your data. Since I made a Tinder account I been getting constant ads for random dating sites. This have been going on for months. God knows how many companies now have my data.

Second, they employ dark patterns:

1) Easy account deletion. Why does that matter? Because they own nearly all dating sites. Including: "BlackPeopleMeet.com, Chemistry.com, Delightful, FriendScout24, HowAboutWe, Match.com, Meetic Group, OkCupid, OurTime, People Media, PlentyOfFish, Tinder, Twoo, Hinge" So, they don't care if they lose a user as long as they can shuffle them around.

2) They will keep a tab of the number of users who have like you. Then eventually that user will shown to you and you will swipe left or right. In that case the tab count will decrease. This is a complete scam. They would withhold these users to push to a pay subscription. Example: https://i.redd.it/e13yeek795x21.jpg . Moreover, most of these likes a bots and fake profiles.

3) Fake notifications: https://i.redd.it/r0lheira9rh31.jpg

4) Shadows-bans: I saw that my profile was getting no matches. So I made a new profile, ban! a match within minutes. Essentially they shadow ban users as a form of Neg.

--I meant they would not* show me the person, so the notification persisted. Pushing people towards paying and unblocking their likes.

I would advice most people to stay away from online dating. Especially if you social anxiety or low self esteem. Why would you place the chances of finding love in the hands of a corporation?

In the case of tinder here is why: After I sign up tinder I started getting constant ads. These ads have followed me for months, to this day. Here is the most recent example: https://imgur.com/a/IJFCG0m.

Most dating apps are owned by a single company Match group. They own for example: BlackPeopleMeet.com, Chemistry.com, Delightful, FriendScout24, HowAboutWe, Match.com, Meetic Group, OkCupid, OurTime, People Media, PlentyOfFish, Tinder, Twoo, Hinge. In fact, tinder's delete account button is very conveniently placed. They don't care if you delete your account... as long as they can shuffle users around. The match group itself is owned by an even bigger corporation IAC. It owns about 150 brands worldwide. For example: TripAdvisor, Expedia, Ask.com, The Daily Beast, About.com, Dictionary.com, Investopedia, among many others.

I have a hard time believing that Tinder have any incentives to make you find date. Why would they do that? You will quit the app and they will stop making money!

I believe they use a lot of dark pattern to try to sell stuff. Here in an example: https://i.redd.it/e13yeek795x21.jpg. When I used tinder they keep the notification "there is someone that like" but they would actually show me the person. Another example of the dark patterns: https://i.redd.it/r0lheira9rh31.jpg. They also shadow-ban users among many other things.

With Quora I learned how real filter bubbles are. During the 2016 elections I used to click on a lot of anti-trump questions. The site painted me a picture that trump was a "joke" and that he no one seriously believe he had a "chance". I was genuinely chock he started winning the primaries.. and then the elections. Looking back I still can't believe that I was so out of touch with reality. I haven't use Quora since them. Nowadays I actively try to ignore Quora when it shows up in search result. But when don't the answers are often short and wrong, or blatant self promotion.

This type of tax incentives should be illegal. A lot of people argue that NYC still benefits from this deal, but we should not be thinking at a city level. But a country level, does the country benefits from this? No.

Has these type of incentives been illegal, Amazon would have to pick a city from the US and the overall US economy would be 1.5 billion richer.

The problem with incentives is that presents a "prisoner dilemma" to cities. And overall drives taxes down.

Sorry for my English.

Minimax search https://www.cs.cornell.edu/courses/cs312/2002sp/lectures/rec... How knew that a couple of line of code could be used cause so many interesting behaviors like cooperation, betrayal etc.

I don't understand this system at all. Only 1 in 200 Phd student ends up becoming a professor, yet in college we have classes of 200-250 students per professor. And some of the older professors have been teaching the same class for many many years, without attempting to change the material. They are just repeating the stuff the already know, over and over again. It seems for me a waste of human resources, for me, to put some of the smartest people in to such repetitive task. Instead, I think the hiring bar for academia positions should be lower, the classes should be smaller, and the student should receive more customize experience.

I found this whole competition for Amazon absurd. Lets think about the prisoner dilemma:

    If A and B each betray the other, each of them serves 2 years in prison
    If A betrays B but B remains silent, A will be set free and B will serve 3 years in prison (and vice versa)
    If A and B both remain silent, both of them will only serve 1 year in prison (on the lesser charge)

Now A, B are cities and the can compete(betray) or not compete(stay silent). If they both compete (1th case) is the worst outcome because Amazon does not need a tax break or incentives. It's one of the richest companies in world already!

A competes, B does not (2th case). Good for city A because they can offer an small incentive an still get Amazon, bad for city B.

A and B do not compete. Good for both as the overall economy of the country would improve.

Not a big fan of Dell but precision 5520 I think is good.

Exactly, these cases are outliers. Yet so many people fail to realize that. Take for example kidnapping, which is the 1th worry for parents, yet in the real world it fall 5000th of the threats to children (by close relative), by stranger I don't think even makes it to the list. The real threat are car crashes, suicide, and drowning which are 1th, 2th and 3th I think. The same think applies to "terrorism", it would be much more efficient to apply the resources to other causes. I think this whole "war on terrorism" and "war on drugs" if just fear mongering that politicians use to try and get elected.
