Second this. Internal referral is the most reliable way to get in the door in my experience.


My interview performance actually got better once I stopped overdressing. I got more offers wearing a grey hoodie and jeans. And this was at big tech (not just startups).


Actually the same person is maintaining Bitcoin. Satoshi is Adam Back, co-founder and CEO of Blockstream.

I don’t know about that.


The FIU bridge is truss bridge, not a cable-stayed bridge, see this NTSB update [1]. The bridge collapsed because it relied on a single truss with no backup to support the weight if it failed. This created a single point of failure where the collapse of any member (diagonal segment) would collapse the entire bridge.

There is no indication that ACB contributed to this collapse, rather, this was a faulty design that would have also posed a risk using traditional construction techniques.

> didn't the wholepoint of using Bitcoin is that there is a public ledger for every move?

There is a public ledger for every public move. If you move money within your own organization there is no publicly visible effect.


BTC trades like an accelerated stock market. Instead of crashing every few decades, it "crashes" every few months.


WHY does it operate like that? Simply because there are no opening hours? It's 24/7?


All currencies trade 24/7 (if they are traded).

The volatility has quite a few causes, among them:

- Other currencies are used for all sorts of things that don't involve trading them–i.e. when have you last thought about exchanging those USD in your pocket for Euro? That creates stability. Compare to bitcoin, where almost everyone owning any keeps an eye on the market and is principally willing to buy or sell when they think they see an opportunity.

- Markets for real currencies operate under government supervision and regulation, and the facts that influence their value, such as employment numbers or GDP growth, are public, and reliable. For bitcoin, some rumour from China can move the market because nobody knows which information to trust.


In another thread I was commenting about the volatility of the currency and how it could be a vanity metric how we give value to it based on its USD conversion rate.

I think this issue will be solved when there are more places accepting BTC. Then you wouldn't need to keep an eye for when to buy/sell it. You would be able to spend it.

I read on /r/btc/ someone saying that "currently, BitCoin are like Magic The Gathering cards". And it really does!


For a worldwide market Bitcoin is tiny. It doesn't take that much real money to significantly shift its value. Regular currencies are padded by the fact that trillions of it are spread across the globe in billions of accounts. With Bitcoin you can have one guy making a measly $50m buy and the market will go crazy. Same with a sell. And then there's all of the pileon effects when the market starts to move fast and people panic.

The smaller a market is the less buffer it has against volatility.


Your argument fits, I noticed that the bigger BTC got, the smaller the volatility.


I can only think of a few the past 4 years. Granted, 2 were in the past 8 months


A 5-10% drop in a single day on the SPX would probably cause a panic. This happens on a regular basis with BTC.


I don't think it's correct to compare index to what basically is a stock.


A stock share is partial ownership of a for-profit venture for gain. Bitcoin is more akin to a precious metal or commodity, except that btc doesn't have any utility value like gold, silver or copper do.

Stocks pay dividends and entitle the owner to certain rights. Btc gives you some crypto that others trust.

Not very similar.


Arguably precious metals don't have much more utility value either.


Gold, platinum, silver and copper all have use in electronics manufacturing and jewelry. Platinum is used in catalytic converters for exhaust treatment. They are very useful.

Btc is actually a detriment to the environment without any real utility. The evidence of work algorithms burn fossil fuels and add CO2 and other pollution into the atmosphere, and at the end of the day, all you have is a bunch of useless 1s and 0s that we attribute with value that are incapable of doing anything other than represent a finite portion of a really complex math problem that we attribute value to.


> Gold, platinum, silver and copper all have use in electronics manufacturing and jewelry.

From my understanding their "actual value" is massively inflated through a similar monopoly as De Beers for diamonds (except it's China as opposed to a single company).

I agree that BTC is a massive determent to the environment and so on, but rare earth mining isn't a picnic either. While all of those materials do have practical uses, their perceived value is massively over-inflated.


Yes, they are both detriments to the environment, but precious metals provide value. Not only do they provide value, but in many cases, once they are used, they may be recycled and used again. You get to amortize the pollution over the lifetime of utility of the material until it can no longer be recovered.


The thing I love about bitcoin is that a $500 swing in a single day (or hour) is completely normal and par for the course. Sort of amusing in how ridiculous it is.


i don't think its crashed at all in the last 8 months. we've seen some shakeups, sure. But I can think of two crashes in the entire history of bitcoin.

June 2011. from 30 down to under $1, and Feb 2014 when MtGox finally imploded.

These last few have been sell offs and market manipulation which only lasted a few days.


> without copyleft we might not have the fertile collaboration of projects such as Linux, git

Why would this be the case? FreeBSD and SVN were developed without copyleft. GPL is not necessary to get people to contribute to open source.


Apple seems like a good example of where someone made a proprietary fork of a non-left license, and made only trivial contributions back.


NeXT's usage of BSD predates BSD being available under any open source license, and as such macOS/iOS's use of it seems like a direct consequence of that rather than it being under a non-left license.


I don't understand why the license at the time is relevant. The point is that if it had been copyleft, they would be required to contribute back.

It wasn't, so they weren't and didn't.


I was under the impression that FreeBSD for years depended on GNU GCC for compilation?

In which case I think it's somewhat (if not completely) misleading to say that "FreeBSD ... [was] developed without copyleft.".

This wasn't a particularly good counterexample, since Linux is more advanced and successful than FreeBSD, and same can by said about git.


By which metric is Linux more advanced than FreeBSD? Companies like Netflix use FreeBSD because its networking stack blows Linux out of the water. Further, how about Xorg, Apache, BIND, Nginx, etc? Significant amounts of userland tools and applications are written under more liberal licenses.


FreeBSD had "containers" aka Jails, more than a decade before Linux. Linux is merely more popular than FreeBSD, and that popularity has zero influence on its quality, I'd argue it might even have a negative impact on its quality in a statistical sense, when you take into consideration all the badly maintained SoC implementations of Linux.


There's a lot of talk here about TCP vs UDP vs SCTP vs x protocol.

It's important to keep in mind that this is all optimization. Don't lose sight of the big picture.

On one RTS we ended up just serializing world state over a TCP socket. If you can get away with the brute force approach then just do it. Don't optimize until you have a measurable performance problem.

While Firebase is proprietary, you can export your database as JSON and import into RethinkDB.


And then rewrite your entire app against a new API. No thanks.


I wish this was true. I am locked-in with Firebase and would love to self-host now that I have resources. Sadly I will have to rewrite the API. It's not that Firebase is not great, I just want to take control back.


To be fair, I think Horizon is one of the more promising Firebase alternatives. However, it has completely different semantics, and is quite immature at this point (look at the limitations: http://horizon.io/docs/limitations/). But if Firebase remains proprietary and Horizon continues to improve I could certainly imagine that rewriting my app will eventually start to look attractive.


Yep. The WHATWG recommends just using the term URL instead of URI.

> Standardize on the term URL. URI and IRI are just confusing. In practice a single algorithm is used for both so keeping them distinct is not helping anyone. URL also easily wins the search result popularity contest.

https://url.spec.whatwg.org/#goals


Thank you so much! I needed an authoritative source to throw at people when they try to belittle me for using URL, instead of URI. To me, URL just sounds better.


And it is more descriptive as well, in the context of web browser addresses: why call something an animal, when you can call it a dog?
