Awesome story and well written.
Why can't it be contractual when death is the alternative? What if I agree to provide X in exchange for someone's kidney? That can't be contractual? Unless there is imminent threat of death, I can see a contract that is entered into by one of the parties in order to avoid death as meeting every condition of consent.
People say there is a bubble, but Marc Andreessen is right that the situation is completely different now. When we started in 1998, our whole startup was on one dialup line, as a T1 was really expensive. We had to take turns downloading files. This was in San Mateo, California, not the middle of nowhere. The sysadmins once put out a request to the developers one time to physically show up and help move all of the servers. Our colo site got mad at us because we packed so many servers in that it overtaxed their air conditioning. Who buys their own servers now?

Now everybody is connected. You really can expect a huge number of normal non-technical people to be able to use your website to do everyday mundane tasks like hail a cab or order food. As Marc points out, all the stupid ideas from the bubble all work now. In 2000, selling pet food online was stupid. Now people buy so much online that physical retail businesses that sell generic stuff like pet food are going out of business.

Not sure if I can can communicate how utterly strange the internet was to most people in 1998. There had never been anything like it. People knew it would change everything, and they were right. It just needed a decade and a half for everyone to get network, get a client machine they liked (iPhone), and learn how to use it. I think Marc is right: this is the deployment phase of the technology. I do not think there will ever be another internet bubble. The next bubble will be in some new technology that does not work yet, like biotech or self-driving cars.

Or, maybe people are now so well-informed and information is in such a tight feedback loop that there will never be that kind of bubble ever again. Bubbles come from ignorance and a slow feedback loop. People forget how hard it was to find information in the past: you literally had to know where to physically go to get it. Now some dude in rural China can find out more about the meeting schedule of subcommittees the North Dakota legislature next week while sitting on the toilet than most people in North Dakota could in 1995 without at the very least making a bunch of phone calls all the time or living in Bismarck and going to the capital ever day: http://www.legis.nd.gov/ I was so confident of that sentence that I guessed that to be true and only searched for the site after writing that sentence: yup, there's an app for that.
Python would be nice if everybody uses Python 3. Simple dynamic and most of the Open source stuff is scriptable using python. So daily automation is a real possibility. Atleast that's what I am doing.
I'm using firefox 50 until it's not safe to do so. When the time comes, it's going to be hard to choose from bad & worse.

Firefox is the only browser out there that supports text-only page zooming! And until recently, the only browser that supported these total-conversion extensions like Vimperator.
By 2000 everyone knew there was going to be a big correction. Few accurately imagined how big. It was like going to the doctors because you knew something was 'a little off' and finding out that you were going to die in three months. Then talking to all your friends and realizing that everyone you knew had the same disease.

Initially many thought it would be similar to the early 90s recession. I.E. A few layoffs with everyone getting hired back again two years later. It wasn't until 2002 that people realized that springtime wasnt coming back.

It wasnt just places like pets.com that crashed. You had every single non-tech company simultaneously scaling back IT initiatives. At the time there was still a large cohort of management types who considered the Internet more of a fad than a new paradigm. These types took full advantage of the shifting winds to cut deeply into anything tech related. This broad overcorrection did a massive amount of damage to the industry.

You can still see the impact crater. Remember the big talent shortages during 2008-2012? Thats because you no longer had a cohort of mid career professionals to draw from. Only the thin number of people who survived the collapse and a bunch of novices who were just getting started. Everyone was missing that valuable group of mid career 8-12 years of experience etc... Basically a generation of careers strangled. Which is why you'll often see no sympathy for the 'talent shortage' complaint. Five years after cutting everything and leaving people to starve you have the same cohort of managers demanding to know "where are all the people with five years of recent experience"
what about Boston Dynamics, the military contractor. There's also Festo, Fanuc, Reis, I'm sure there are a ton of other robotics companies that we don't hear about because most robotics companies are marketing to very specific applications on the business side rather than the consumer side.
I once went to a code review in a very, very large (but now defunct) corporation. The author of the code did not allocation the memory they were writing into. There were 8 people at the code review. I could not convince a single person that writing into unallocated memory was a bad idea. "Allocating the memory would be slow", they countered. "And besides, we've tested it and it doesn't crash".

Sometimes you can help people become better programmers. Sometimes you can't. Try not to stick around in positions where you don't have the ability/opportunity to make a positive contribution, is my best advice.

But assuming that the person is willing to listen to you, all of the above seem like good approaches.
Reading anything written by a company like trendmicro can be really annoying.

They tend to litter all their discoveries with FUD in order to maximize their sales.
It's not so much as trouble with pointers as trouble with visualizing algorithms and data structures. Try implementing some moderately complex one in C. It reads like a monster. A dynamic language like Python would have a simpler implementation but at the cost of performance (Why do beginners need performance).
Even random apks are analyzed by the same service that is used by the play store.

It is still more dangerous, but known signatures are detected.
This is so awesome on so many levels.

Congratulations byteCoder!

I've had to witness my brother in law dying because of cancer. It's horrible.

Removing the option the ability to disable javascript was a deal breaker for me. Luckily I could sort of restore this much needed feature through extensions.

The other browser that got it and offered a quick menu to disable/enable javascript was opera with the f12 or quick preferences menu, not sure if this option survived opera selling out and becoming a chrome skin.

Pocket was another thing not needed to disable in firefox, it was proprietary and had vulnerabilites when a better opensource alternative existed, mozilla got a lot of flak for this. Then they bought it for millions of $ to leverage the users to get into mobile.

Hello was again another unneeded thing to disable right away (yay more extensions!), it leaked the local IP and added vulnerability.It was such a popular feature that it got removed a few versions later.

Those 3 really infuriated me and a portion of the firefox users community.

I can't tell about the memory usage, I've bought a 16GB RAM laptop a few years ago to free myself from firefox memory issues, I do know that once in a while I have to quit firefox because it's consuming too much memory and cpu while idle.

by the time e10s arrived, there was no "vast majority of users" anymore for firefox. Having not heard of it means mozilla communication sucks. Anyways e10s is disabled in my firefox, I do not remember why.

I'm not sure what you mean by firefox being the last browser to support xp, 6 months ago I tried to install firefox on windows xp and installer denied to install telling me it does not support xp anymore. I think I installed pale moon instead and opera so maybe firefox is not the last one to support xp.

Signed extensions caused an uproar and some people left firefox over this because it's removing freedom from user and giving more power/control to firefox. I had to drop a couple extensions that refused to comply with mozilla demands or were not updated.

And there are other things like this, and when all this happens while bug report dating of years or decades are still waiting to be dealt with or closed as WONTFIX because you do not matter enough, well...
> Newspapers aren't credible anymore because they continuously make the conscious decision to run bullshit stories full of twisted truths in the pursuit of sales, as they have always done.

Sources for that claim please?

Of course there were always plenty of papers that operated like that (tabloids etc), but I doubt they were as influential in main political discussion as e.g. Fox News seems to be today.
It's nice to see innovation in the railways. Kinda sad in the UK we don't seem to do much, if any, innovation these days :(

I honestly don't believe breitbart and the guardian are equally bad. There have always been varying degrees of bias and different degrees of standards.

The right spins this as everyone is equally biased in order to justify there readers picking their own alternative facts to justify whatever positions they hold however improbable.
SoftBank raised $100 billion (!!) for investment: https://techcrunch.com/2017/05/20/softbank-vision-fund-first.... It's no wonder that SoftBank seems like it participates in many startup funding rounds.

This seems like a bad idea - there are only so many good startups at any given moment to fund, so a lot of the money will go towards non-viable startups.

> The US market is where pharmaceutical companies expect to recoup their R&D costs.

They could do this in two ways - having high margins on their drugs, and/or selling a lot of drugs. It is no surprise to see pharma lobbying against tight laws on prescriptions, or anything that gets in the way of the 'market' getting access to their products. Not coincidentally, the opioid crises means they get to sell more drugs.

Or Haskell if you want to go the FP route while CL or Clojure for the Lisp. Or python for dynamic (atleast more popular than Ruby which is more concentrated on Rails ecosystem).

I repeatedly tried "living in another search-engine" for a month at a time. I tried Bing, DDG and Yahoo. If I didn't search for something easy (like "population new york") the results were useless and superficial.

Searching for something like "programatically create credit memo magento" yielded the user documentation on how to create a credit memo while Googles first result was the relevant API page with the second being forum posts explaining how to do what I wanted.

If you need specific results and don't get them, you go back to Google.

>It's not unreasonable to wait until battery costs come down so mass adoption comes naturally.

But how will battery costs come down if no one invests in it? You sound like the people in my country, forever waiting for the price of wind turbines to drop.

The Danish, German and Dutch government handed out massive subsidies for the first wind parks. Now, because of those subsidies, subsequent wind turbine parks can be built without any subsidies.

But that would've never been possible without those initial investments.
>A 40-year study published in 2012 found that writers are more likely than people in other, less creative occupations to suffer from mental illnesses such as bipolar, depression, and general anxiety disorder.

This bothers me. It's correlated but the following analysis assumes at least partly that being a writer is one possible factor for depression. Very common mistake most HNers are probably aware of.

For a science writer to read papers so wrongly is rather ironic.

So wait, this means that if it weren't for safety and emission standards I'd be able to go out and buy a new car for 4000 dollars and a used car for a tiny fraction of that? I get that others want safety, but for me that's not as important as avoiding debt. Shouldn't I have the right to make that choice on my own?
I'd be very curious about the stats. Above 35-40 you quickly notice a change in momentum. At least a car might have better brakes and stability.

Very true – the price hasn't really moved in response to this news, which makes very little sense to me. I'd be shorting if I could figure out how.

Chrome has other advantages as well.

If you buy into the Google Suite then you get synched profiles. Firefox has the same but the account is only useful for keeping Firefox in sync whereas Google's also give you access to all their other products, plus oauth to third party services.

Google Chrome exists inside of an ecosystem, which means that is stays simple. On the other hand, Mozilla has a tendency of treating the browser as a goal in itself, which is understandable but creates things like the Pocket extension and other UX complexities.

Android's unremovable Google search doesn't open the default browser but presents the result in a Chrome WebViewer.
There is no guarantee that battery costs will come down naturally. The point of the subsidy is to help drive demand long enough so that the market forces have time to work on bringing those costs down. And even then, there is no guarantee that this will work. But batteries are a critical technology for many reasons (particularly the grid), so it makes sense to target this technology specifically. Look at what the CSI program did to CA's solar industry for an example of how fast a well planned incentive program can bootstrap an industry.

Also, CA already has a cap and trade program (a bill just passed to extend the program another 10 years). It has been around since 2012.

How is the charging time and mileage on Zoe vs. Model X?
One thing the author didn't touch upon is the amount of manpower available on both sides. I am under the impression that Google has much less people involved in the construction of their browsers.

therapy is more useful than drugs, even if drugs are needed eventually.

I have similar feelings, I started my own startup just out of college and feel like that was a waste of time.

I had never shipped any code more than college assignments, there were some classes on entrepreneurship and business but they were so shallow, I had no professional experience and little knowledge outside of academia, I had no network or audience, I didn't know how to run a team which consisted of my college buddies.

After working in a big corporation, big startup, bootstrapped startup and more environments I feel way more prepared and motivated, I know now how to do most of the things I didn't, I have a much bigger network and I know how an actual workplace functions and I feel confident enough I can do it myself.
Thank you for finding the joke laughable.
Time for a new search engine maybe?

Duckduckgo seems like the obvious alternative search engine these days, but how much of their own indexing do they do? It seems from some casual googling (no, the irony of that is not lost on me) that they mostly rely on Bing or Yahoo as the backend.

Some thoughts:

Search engines should be a lot easier to build in 2017 than they were two decades ago when Google started out. We don't have to store the index in DRAM to avoid hard drive seek times like they did; we can use SSDs.

Having a good quality ranking metric could offset shortcomings in the size of the index. PageRank is okay, but we could do better by punishing sites that link to low-quality content.

Speaking of PageRank, the PageRank patent expires in a couple years, I believe. So, constructing ranking algorithms that build on PageRank will soon be an option.

It's hard to compete with Google and Bing in terms of hardware resources, but probably the minimum investment to build a useful search engine is probably at lot lower than what we might think.

A lot of the basic software infrastructure is probably already written. I don't know what the state-of-the-art in web crawlers is, but in 2017 I doubt that one would have to write one from scratch.

Maybe there's a way to build a shared/federated distributed index.

Running the project as a non-profit might be the best way to maintain trust of users. Not having any ads at all (like Wikipedia) might be a good way to one-up Google's previous policy of no ads/news on the front page.
This is not true for even the best entrepreneurs of our times...many are divorced multiple times so gambling on staying married is a bigger risk. Elon Musk and Sergey Brin are just a couple examples. Your spouse can dump you at any second no matter how secure you think your relationship is.

You may be correct but surely you recognize that the left can just as easily be accused of the same bias you attribute to the right?

The real problem is diverging narratives and very little constructive communication between. Both sides have very valid concerns that aren't understood by the other.

I don't like Python, but I have to admit that it ticks most of the boxes of an ideal starter programming language, unlike CL, Clojure, other Lisps, Ruby, or C/C++.
Completely agree. They can be lucky if these panels power on board electricity and air conditioning (in new trains that have those) but that's about it.

A diesel locomotive and full trainsets is hundreds of tons heavy. You can't propel these with a handful of solar panels on top.
