I got laser surgery done and that left a big scar on my neck, can confirm 10 years later I'm still functioning properly. Now the liver is different but from reading the article it seems this was just a stupid non-life-threatening decision taken by a surgeon who thought he was painting on canvas
First, Chinese government has no human rights abuse in Tibet; they developed the area and treat the people well.
Second, corruption is everywhere, if there is not China, there will be another country. The election system is not to find the people loyal to voters.
He is not just a mechanic operating on inanimate objects, his "handiwork" was the insides of a person. Letting vanity get to your head and signing your initials inside of them is a gross violation of the autonomy of that person -- they never consented to such a thing.
I moved from Austin to SV, tried to do a start up there and all.

In my experience the average startup scene (angels, VCs, tech talents, etc) are pretty much all bush league when compared to Silicon Valley, despite some of the glaring flaws of SV startup scene. There are exceptions to the rules, but I was mostly unimpressed during my time there.

Austin Ventures was the biggest VC in town back then (probably still is), and I've heard that the unwritten rule for the firm is that they do not invest in first time founders.

That tells you how risk-averse and "open minded" Austin tech scene is.

But with Tim Ferriss's reputation and background, Austin is a great place to be because he gets to be the big fish in the small, growing pond. I'm sure he's doing very well at the local speaker scene.
Article author actually makes a great point and it stands regardless of your ability to cash out within 1%. Big investors on current markets can whip out huge profits for themselves by using techniques such as front running, wash trades, willybot, spoofing etc. Exchanges are not even prohibited from doing their own secret trades and using their own internal database and full knowledge of all other players.

If you are a trader with deep pockets, you should immediately realize all above established techniques (which is illegal on stock market) can generate you huge profits in no time in crypto market. Big players would literally have all the strings to play the market according to their will. Currently prices are 100X higher and 1% difference seems irrelevant but in mature markets 1% move is news worthy event.

I think its also worth pointing out that less than 1000 entities owns 40% of the bitcoins. I wouldn't be surprised if set of entities are willing to burn short term cash to inflate the prices just to attract other large scale investors in the game. This is like burning tinder to start the fire. The end game usually is massive cash outs as soon as fire has started. Typically this would kill the fire but in some cases it may keep going. In any case, the bad news to small investors is that expect to get killed at any point in time when your big brother decides to cash out. Until then, party on.
SQLAlchemy makes dropping down to SQL where necessary incredibly easy. There where necessary you can tune the queries, but where not necessary you can let the ORM create them for you.

This gives you a lot of flexibility and power, but as zzzeek mentioned, you need to know SQL to understand how what the ORM is inefficient and to be able to replace it as necessary while still letting the ORM do what it is really good at.
> I'm as socially liberal as you get, and I find it nauseating how many topics or dissenting opinions are simply out-of-bounds in Silicon Valley.

Saying this in such a generic form, without actually mentioning what any of the topics or dissenting opinions are, raises a red flag for me.
Are there programmers these days that actually don't know SQL? I find that hard to believe, that's gotta be like a CS 101 course.
> ...in order to use ORMs effectively, you still need to know SQL. My contention with ORMs is that, if you need to know SQL, just use SQL since it prevents the need to know how non-SQL gets translated to SQL.

This is presuming that you will never come across ORM being used almost exclusively in any future projects. After all, ORM doesn't seem to be going anywhere (even with all the hate against it). One could make an argument that learning both effectively would provide a better general foundation.
Thanks for so many good examples and generally a decent writeup. You say you've considered writing articles; I'd say it's a good idea.

Favouriting this comment for reference the next time I have to bring this topic up here.
How should India regulate the ticking time bomb called Bitcoin?
He is on point. The common way to approach any questioning of the common way of thinking is to always deny, never admit to anything and make counter accusations.

The questions are never answered, and the counter accusations are aggressive charicatures that most often has little relation to what was claimed.

I personally find this more scary than McCarthyism because while it used the judicial process, the current attitude is to rule by mob with no process and without hearing both sides.

Our democracy is fragile and rely on us respecting the rule of law . These people have the power to ruin people’s lives and use it. They should be ashamed for risking our democracy in this way for short term gain, in the naive belief that democracy is the default state of a society.
If you lose a job, you just lose the income stream and 2 weeks of salary at most (+ whatever time it takes to find a new job). With an investment there's a risk of losing the asset entirely. Rental property gets buried in a landslide, company goes bankrupt, gold gets stolen etc. There's also the risk of not making any return at all: rental property remains vacant, company barely breaks even, gold only tracks inflation etc.

> investment in bonds backed by the US government.

Those bonds have a correspondingly low yield, to reflect their low risk.
You were doing it wrong then. EF does not eagerly load child collections. You cannot even configure it to do so.

As someone else suggested, you probably had lazy loading enabled, and some of your code tried - e.g. through reflection - to get all properties.

EF has some of it's own issues - but you can most certainly create composite primary keys, composite foreign keys and work with projections right from within the code.

None of the issues the original author had with SQLAcademy and Hibernate are really a pain in EF.

Some prefer to switch off lazy loading in EF and instead either explicit eagerly load specific child collections or explicitly load them right before use.

In EF you can do

var customers = Customers.Include(c => c.Orders).Single(c => c.CustomerNo == '1234')

This will load Customer '1234' with the Orders collection eagerly loaded.

I suspect a lot of inequality is due to better access to wider markets. How rich could you get if your marketplace was just your village? Now, with the internet and cheap global transport, an entrepreneur has access to the globe, and so can make much more money.
Market cap makes more sense for a stock, because it's in the range of the value for a company, and a whole company is something that does get bought and sold. This idea doesn't make any sense for a crypto.

I always wondered about that. Especially since people (and hucksters, trying to sell their wares) refer to Bitcoins as crypto currency.

I'm not a financial wiz kid, but market cap for a currency doesn't make any frigging sense to begin with.

Sure, you can count the amount floating around for a currency on various levelse (ususally expressed in mx) but I never felt that it makes sense to define this as "market cap".

The whole situation really reminds me of the Dutch tulip mania (https://en.wikipedia.org/wiki/Tulip_mania, the first speculative bubble in history).

At least with your "investment" there you were able to plant pretty flowers. Here, I fear, that a lot of small investors will get burned very, very badly.

"All tokens which will ever exist were created on day one and pre-distributed to people who signed onto the project very early." It sounds to me like they are pretty up front about their intention to take all of your money. That is how they started. Same for Bitcoin, only Bitcoin hides it behind a schedule of mining fees so it is more Ponzi scheme while this is more television priest.
That is something I still don't understand about the modern Netflix recommendation engine. Before the percentage system, it would literally recommend things to me that it predicted I'd give two stars. It's probably still recommending things in that range today, but I gave up consulting it.
Not to sound like an asshole but we've read this type of "interviews with VCs" at least weekly lately...and they ALL say the same stuff over and over. Its all "great founders", "great market", "great team" dreamy stories.
Are you saying that it's appropriate to give arguably good unsolicited advice to strangers about their appearance?
The problem with the word "generics" is that it already meant something else in programming language theory. If I used reflection to implement a serialisation function in Java or C#, it could be generic with respect to the data-type of the value passed in, but not parametric. A parametric polymorphic function strictly has the same behaviour for all types, a generic one has type-dependent behaviour. This matters of course when we want to reason about programs.

Thank you very much for sharing this
A normal corporate stock price and hence market capitalization, is entirely a function of its actual book value (assets minus liabilities) and a factor representing expectations of future profits.

Bitcoins price and hence market capitalization, is entirely based on speculative buying and selling. It has no value if there are no speculative buyers, and that day will come.

What really saddens me is that the noble aspirations of Bitcoin being a decentralized, transparent medium of exchange and store of value, have been so totally crushed in the face of crazy bubble scale speculation.
Austin sucks. Don’t move here.
Wow Github could do with some "pagination" for large files - opened the link on my not-i7-macbook and felt the performance hit...
Ofcourse, and that's a good thing, but networked doesn't have to be the internet. Why have that connected to the internet? And not some setup where it is physically or at least reasonably physically seperated. Those values would also be fine on the LAN. Not networked is safer than networked, but connecting them to the actual internet (via usually not more than some basic router) is the other extreme.
> the gentrification is out of control

I'm a native Texan[0] and I have to say, I wonder where all of the angst about gentrifying Texas has come from over the last twenty years. Everyone has been gentrifying Texas for as long as I've been alive[1]. I watched my hometown go from a sleepy Dallas bedroom suburb 30 minutes from anything to six-figures of population and now a proper business headquarters in its own right. It even has its own live music venue and three (THREE!) actual rail public transportation stations. I never thought I'd see the day.

Nobody seemed to much care when it was Californians[2] selling off their million-dollar beach houses and buying four-acre ranchettes in the Dallas, Houston, and Austin suburbs. But now that Californians[2] are selling off their two-million-dollar inland houses and buying townhouses in the city, people cry foul.

What do people expect to happen when a lot of folks show up and want to live in an area? Folks have always gone where the jobs are and now some of those jobs pay a shitload of money and are actually located inside the urban area. I mean, I guess we could keep doing the other thing we've been doing in abundance, which is making one solid Metroplex from the Red River to Hillsboro, but that seems a little wasteful these days, especially since the reservoirs don't look like they can keep up...

0 - I write this only as "where I come from," not as any particular authority on anything besides my own vision.

1 - A lot longer than the average tech worker these days, for sure.

2 - Not a dog on Californians, just they're the most common folks to pack up and move east, particularly since moving west gets a little damp.
Even for films you haven't seen, it's a pretty terrible system. I didn't see Good Will Hunting until maybe a decade after it came out, but I was aware of it and knew it starred Matt Damon. If I had looked for it on Netflix and found a cover with Robin Williams, I might have wondered - was this another film with the same title?
Yes, but my question wasn't "What if you had an unavoidable scar from laser surgery", my question was "would you feel harmed if I burnt my initials into some not-normally visible part of your skin" for no other reason than to say that I was there?

Even minor scarring adds to the bodies burden in healing, so I think it's hard to definitively say that the laser inscribed initials did not cause any harm or increased risk at all. After all, these were not strong, healthy people -- they were sick enough to require liver surgery... and one of them had to have followup treatment which is when the initials were discovered.

If I understand correctly, the victims are getting gagged. Not the news medias. They can publish stuff and they did in the past, like that The Fifth Estate thing. So I could have heard about it but I didn't. From the news or from people. Maybe the news don't talk about it often enough or that the population don't care.
I mean, stored procedures are fine, but I don't think that actually solves anything? Except maybe for reducing the amount of SQL code you have to send back and forth and (in some databases) allowing for a few more optimizations?

If you use stored procedures, all you've done is move part of the model into the database, so you have to update the stored procedures as part of a deployment. You still need to have the SQL code written out somewhere, and you still need to have something in the application code that knows which procedures exist and how to use the data they return in business logic.

This article is pure FUD with lies.

1) The spread is not "plus or minus $500", it's a lot less. See for yourself:

http://bitcoinity.org/markets/bitstamp/USD

At this particular moment the spread is $23 on Bitstamp, zero on GDAX, $11 on Bitfinex, zero on Kraken, zero on it it (where "zero" is something under a dollar, there's not enough precision to display it).

2) Yes, you can cash out, a lot. There are dozens of huge exchanges where the daily volume is in billions.

https://coinmarketcap.com/currencies/bitcoin/#markets

For instance, Bitfinex USD/BTC 24-hr volume is $1.2 billion.

And that's just one currency pair on one exchange.

What benefit do you think it would have to bring up what he dissents on if he is correct? Assuming he is correct that would risk proving his point in a way that distracts from the debate he is trying to start.
Only temporarily.

Once issues stop getting public attention they try again and usually succeed.
Given your description of your job, I have a quick question:

I have found that when I speak, I rarely command attention and captivate as some others do. Probably something in my speech patterns. Perhaps they are slightly more apologetic / geeky / nice than others. People may interrupt me or turn away, even people who respect me.

When I do get rapt attention, such as teaching a class, I get an impostor syndrome because I'm not that used to it. I don't let it show - and I finish my thoughts. But I feel my speech is more rambling and unfocused than it should be. I have so many asides that I want to get to, and I like to speak using true sentences so I hedge what I say sometimes, and other times don't make overly ambitious claims.

Is there a way I can improve this? What do you see in your experience?
> shady consideration for the money - check until proven otherwise.

I don't think that actually is correct. The Mozilla Foundation is a non-profit, as has already been pointed out above. As such, they specify a mission and then are legally forced to invest all money that they make/get into this mission.

And in their mission statement, they specify that "Individuals’ security and privacy on the Internet are fundamental and must not be treated as optional." (Principle 4 in the Manifesto).

So, they cannot legally do shady stuff. And even if that means nothing else to you, the rule with law violations still is "Innocent until proven otherwise".
I've never hunted in Germany, and New Zealand has very different hunting, but from all the Europeans that I've talked to, deer hunting is a managed system.

It's not as simple as "keep the woods overpopulated". For starters, you tend to want to keep a good bloodline going. So hunters will cull off the deer of weaker bloodlines.

You also don't want excessive competition, because you don't want malnourished deer. So there is incentive to keep the numbers at a manageable level.

Lastly, there is actually a legal minimum number of deer that hunters need to shoot a year. They are required to harvest a certain number of animals.
Yeah. Pre-enlightnment...

But a certain amount of wealth distribution could improve the life quality of those born with less potential.
Quick response to some of the comments here:

- WebRTC is great in theory, terrible in practice (doesn't work very well), and still needs a bootstrapping server. So it is better to have a reliable websocket based server as the default/fallback, and WebRTC progressively enhanced.

- Signal and Whatsapp, as others have pointed out, are far from being comfortable as being private (they already know too much, phone number, etc.), and don't have the convenience of a browser based app.

- Yes, this app should be using the Web Crypto API (it is what we switched over to, for our P2P cryptographic user accounts: https://github.com/amark/gun/wiki/auth ) to reduce dependency on the server. You can use the `integrity` attribute to help out with this, but ultimately unless somebody installs it as an Electron app or something, browser based crypto has its limitations.
