I'm not a data scientist, but I think selection of data, without a larger timeline 'might' be seriously skewing the perspective.

2008 was a huge crash in financial systems. Using that year as a base-line or anything within the few years after, during the recovery 'might' not be reflective of what the actual landscape looks like.

I'm surprised to see 2% of Series A > $50m, but how many were there in 2006, 2007?

Also, the conclusion that the venture market is changing also may be a perspective. Did the venture market change, or did the economics of the companies change? This may be a straw-man argument, but the capital needs of companies like Uber and MagicLeap, where they are RAISING billion dollar rounds could skew the data significantly. How does that effect the actual venture market change? Don't we need to throw out the high and the low?
So then it is not correct to say a semantic patch is a lint rule. Rather semantic patches are both tools that attack the same problem from different angles. Arguably semantic patches are far superior if they can really be made to work.

> I, personally, have seen many projects burning thousands a month in database costs because they prefer replicating the environment for testing branches.

If this is the premise for serverless database it's a weak start. If you really need lightweight DBMS for testing just run MySQL or PostgreSQL in Docker. If you really need access to production-like data (e.g., a lot of it so you get realistic distributions) run the same DBMS on cheap hardware or cheap instances. In both cases you can use persistent volumes and shut down when things are not in use. Few people really care if it takes a few minutes to spin up the test environment.

As for the main point of Aurora offering a "Serverless" architecture it looks as if what they've really done is enabled the DBMS compute layer to scale up and down quickly. I wonder if this optimization fell out of pushing redo log management down into the storage layer. (See Section 3.1 https://www.allthingsdistributed.com/files/p1041-verbitski.p... for details.)
What?
Have the 3 letter orgs fallen of their rockers?
Are the 3 letter orgs now Tin Hat Wearing Conspiracy Theorists? They are crazy to think china is tracking our communications with hardware embedded or pcb embedded components!! wackos!

As they used to say about anyone who would suggest such a thing; dismiss the conspiracy theorists they are crazy.

Remember the 3 letter orgs called the guy who said long throw mics were in Comcast cable boxes? He ripped one open on public access tv to reveal it.

Remember when the 3 letter orgs called the guy who said they have a search engine that made all private comms of the world (INCLUDING AMERICANS) key word searchable? Snowden blew that one wide open. Who is the traitor the people spying on all our comms or the guy who exposed it? unclear.

Metadata" by their definition is all our footprint and text source of the comm.

Wow, they have the audacity to suggest a china national corporation would embed surveillance components in devices worldwide. The Gods must be crazy.
I hope the project didn’t have ill intentions but it would be good to make sure the rebase wasn’t accidental because “git” is famous for letting people perform surprisingly-irreversible actions on repos.
> I think the game that impressed me most at the time was Need For Speed 2 Special Edition, before the card I had it installed and played, but the "Special Edition" was for being compatible with 3DFX and adding additional features, in addition to the smoothed textures, in a track mosquitoes were sticking to the screen, I do not remember what other special features.

I think NFS2SE had transparent glass if you had a 3DFX card, or maybe that was NFS3, I remember wishing I had one either way!

Just seems like a clusterfuck to get the damn thing, the foundation exam is dead simple. I'm totally unsurprised by the dwindling popularity of amateur radio here. Even if the difficulty isn't the driving factor, I'm sure it deters lots of people who otherwise would be interested.

"There is a risk of letting any company "beholden to foreign governments" inside the country's telecommunications infrastructure, he said."

At it's face value this is indeed true. However, it is interesting there is no mention of Samsung then, right? Why would they be exempt from this recommendation, especially given Samsung phones are hundreds or perhaps thousands of times more prevalent than Huawei and ZTE phones in the US.

Shouldn't the argument from the FBI, CIA, and NSA be that US citizens shouldn't purchase any non-US manufactured phone? I'm skeptical as to the true purpose of the statement. This might possibly indicate that for whatever reason Huawei and ZTE don't play ball with the US when it comes to surveillance and the US intelligence agencies don't like it. If anything, this just raised the probability of me purchasing one of these phones. I'll probably stick with BlackBerry, but I will at least consider these next time I need to buy a new phone.
Yes, Genius for news is a fair analogy. You do have to actually justify your tag with a coherent argument, so it would take a fair bit of effort. Something like "CNN is fake news" wouldn't really pass muster.

Regarding three-phase power:

The electrical outlets in your home have two power-carrying prongs. The third prong is just for safety (it connects to the ground), and should never carry power unless something is going horribly wrong. In that case, the power should hopefully prefer to reach the ground through that third wire than through your human body.

Anyhow, the voltage in those two power-carrying wires is constantly switching directions. At one moment, the left wire will be +170 volts relative to the right wire, and then they will slowly switch places over the next 1/120 of a second so the right wire is at +170 volts. They continue trading places, completing a cycle every 1/60 of a second.

At some point in this cycle, the voltage difference between the two wires will be zero, which means that no power will be flowing at that moment (power = voltage * current). On the average, the wires will deliver the same amount of power as-if they had a constant 120 volts between them, which is why people say that electricity in the USA runs at 120VAC. The peak-to-peak voltage is 170V, but the "RMS" average voltage is 1/√2 of that, or 120V.

Anyhow, those brief moments of time where no power is flowing are a problem for a power company, who would like to deliver energy in a continuous stream. So, they build their power system with three wires. Each wire reaches its maximum voltage 1/180 of a second after the previous wire. Since the voltages on each wire are sine waves, when one wire is at 0, the other wires are at +√3/2 and -√3/2 of their maximum voltages. Therefore, there is no point where the power stops. In fact, due to a mathematical quirk, the power delivery is actually constant, even though the voltages on the three wires are constantly changing.

Turing three-phase voltage into two phase voltage is pretty easy. Just pick any two of the three wires and hook them into the home. The difference of any two sine waves is just another sine wave at the same frequency, so you automatically have single-phase power. In practice, the power company will try to balance the load between the three pairs of wires by sending different pairs into different houses or even neighborhoods.

Edit: As several people have pointed out, this isn't quite how it works in real life. See the comments below for details about the hot vs. neutral wire and how both 240V and 120V are available in the home at the same time.
> But CloudFront charges $600 per month for custom SSL certificates

This is misleading. Cloudfront doesn't charge anything for putting your domains on an SSL cert that uses SNI. They only change you if you need a cert without SNI, which requires them to allocate a dedicated IP address to you.

I'm hosting my personal blog on S3 and cloudfront, with SSL, for less than a dollar a month.

Yea, the current US economy is debt-based with government bonds, which is the main way they are able to import more goods without hyperinflation.
Like others have mentioned, EFS has it's own surprises. To get decent performance, you will see a lot of recommendations to store at least 1TiB on EFS to get decent performance (so if your working set is 100MiB, store, you need 999GiB of garbage), meaning you will spend $300/mo for capacity you don't need.
My prediction is that this is wrong. They'll be able to understand widely used terms, but once you start speaking in a more creative way it will fail. At least if there is no change in the construction of AI - because the subtleties of everyday language are not 'understandable' just via empirics.

A simple bill would be to set the maximum spendable amount on any app to, say, $60. In the early days of buying video games outright, they often charged about that. Now, why the hell should it be possible to repeatedly buy absurdly-priced game items, especially when at any time the developer can further modify the code to devalue the item later (e.g. with new, even more expensive gear better than what previously seemed worth paying for)?
You are wrong in assuming I don't know about cryptography and it's fundamentals. I'm not a professional expert in them, but I do have formal theoretical and implementation experience.

The "don't roll your own crypto" is simply wrong in general. For comparison, most often injecting chemical agents into your veins in high concentration is highly detrimental, so most often the rule "don't inject highly concentrated chemicals into your blood" is valid, but sometimes the chemical is an antidote and is the only way to save a life. Therefore, in general, the rule "don't inject concentrated chemicals into your blood" isn't valid. It's the same with cryptography. There are tradeoffs at play and one needs to know what they are trying to achieve. Custom cryptography is a (rarely used) tool in the box, but it is rightfully there.

Maybe this is a misunderstanding. I certainly would tell children never to inject chemicals into their veins, but I wouldn't tell that so absolutely to an adult. I treat people here with respect and as adults. That's why I nitpick and say "don't rule your own crypto" isn't true in general.

A good book on this and related subjects is

The problem is not because cryptoassets are bad, it's because you read an investment book instead of technology book. (I read the cryptoassets book too and I think it's a great book, it's just that it's not a book to solve the specific problem you're talking about)

I can confirm from my own experience that reading pop-sci books about blockchains--although they sound really cool and do provide motivation to look further into the tech--doesn't give you any confidence about the technology itself.

There's no shortcut, if you want to be more "enlightened", you should stop reading medium blog posts or pop-sci books and start looking into the protocol itself, run a node yourself, and try stuff out. When you do so, you'll get the "enlightment" you were looking for.
MySpace, tumbler and digg are probably good examples.
The headline seems sensationalized. The article doesn't mention a recommendation not to use, it simply was the absence of a recommendation at all.

"...asked the group to raise their hands if they would recommend private American citizens use products or services made by Apple competitor Huawei or smartphone maker ZTE."

The US Government is not in the business of recommending device brands or services to private individuals, and not making a recommendation is not the same as recommending against.
> And I must say I really enjoyed the Dutch system where you don't have to print paper every time.

Heh, when we went Amsterdam - Berlin and vice versa we had to print our tickets. We even reserved seats. I quite like that system. One has to reserve in advance if one wants to save costs though.

The downside of the Dutch system is its easy for the government and railroad employees to check where you went. There was even a recent scandal about this, where an API was public which showed the transactions. The price of the transactions could be correlated with the cities the traveller traveled to and from.

In Germany, you have more anonymity thanks to being dependent on paying with cash and paper tickets.

Look, if, with exactly the same cost attached, people don't want that by choice... fair enough. However we don't that choice. And if you travel like 3 times a year a long trip through The Netherlands the 40% discount in down time hours is already worth it. Which is not anonymous but linked to your name. The anonymous card is a joke anyway; not my definition of anonymity that is for sure.
In computational acoustics, I've seen "codes" used more commonly, especially by those who started out in the punchcard days.
Terminating is impossible. They made it that way and have told this numerous times.

Three phase power distribution is also more economical in terms of wiring. You need less conductor to distribute the same amount of power compared to running using two phase.

I read that book too, and while it does provide some good insights, it's too much biased the other way around to the point that I couldn't stand the amount of snark.

I think it's good to take a look at both sides of the story but the only way to find the truth is going deeper and learning the protocol yourself and form your own "sovereign" opinion, which is what I did after getting frustrated with tons of conflicting opinions online, which by the way turned out to be mostly propaganda to preserve their own crypto-wealth as I started learning more about the landscape.
If you were to choose a car solely because of its infotainment system, what would you go with? Thought about that as was struggling with a conference call from my car this morning.

I wonder if this thread has fallen into the trap of talking about the fashionable stuff instead of what is actually in use...in the same way a newcomer to software on HN might be forgiven for thinking that the majority of software is written in Node or Rust, and rather underrepresented the amount of Java actually in use.

When I hear Agile, experience has taught me to suspect that these guys don't spend enough time writing requirements. In the mid market web agencies Agile is a synonym for 'we don't do project management.

I visited a software company recently who are still using a lot of VB6(!), and they are having a big drive to modernize. But instead of finding a new GUI framework they just employed a Scrum-master to re-arrange the deck chairs on their Titanic and some ex-Oracle sales guys to paper over the cracks.

I suspect in the UK, if you are to be engaged on a project to implement a new feature for an enterprise customer like a bank, or you are in a mixed hardware/software environment you may see Kanban/Agile for little sub-teams, but the actual project will be running under Prince2.

Prince2 is how you do projects in UK enterprise/government, and if you are writing software as part of an enterprise project you will be under Prince2 as well. However Prince2 is pretty flexible about letting you run individual tasks the way you want, don't expect to be able to reshape requirements on the fly without having to justify how that affects the 'business case'

I would be interested to hear if that was not anyone else's experience?

This is the weirdest rationalization of three-phase power I've ever read. By your reasoning and disregarding cos phi issues, monophase power is also constant-zero power, since it's two wires anyway and one is always the opposite of the other.

The best explanation of why three I was ever given hinged on "it's the number-of-phases argmin for the needed volume of wiring".
Indeed when we lived in London I could earlier walk, then get a bus and then get a tube and that would take about an hour to get to work.

Don't know. But it makes the world more awesome.
Moving forward, developers will seek to protect the network’s ASIC resistance by slightly modifying its PoW algorithm at every scheduled hard fork, which generally occurs twice annually.

I presume they've considered this, but this seems like a dangerous approach. How will they decide which change occurs, how far advance will it be decided, and how will they keep this decision secret? Think of the potential advantage to a party who uses foreknowledge of the exact change to have ASIC's ready at the official announcement. If done on a small scale, it's possible that no one would ever know. If done on a large scale, it would be obvious after the fact that a leak had occurred, but the repercussions would likely destroy the currency.
