I was thinking "what if you increase the frequency to where the eye doesn't care" then I thought about how radio waves pass through our bodies and I remembered: wait a second, there is just one radiomagnetic spectrum!!!

As a page I googled states: "Optical radiation called light is the same thing as x-ray radiation is the same thing as microwave radiation is the same as infrared radiation is the same as radio waves."

0f course, when I think of radio waves they radiate out all over the place - but so does most light that isn't a laser.

Is there a "laser" in the higher, safe radio frequencies (which just pass through the body)? By laser I mean it's super focused with very tight parallel rays.

Could this be put in place of this system? After all the hard part of this system is aiming the laser, which this article says is done through active "sonar" (an acoustic beacon which is then localized).

Why not then target it with a radio "laser"?

Worth reading is very subjective. I think you are looking at popular opinions. The current system works that way as opposed to some randomized insertion in between. One often problem with popular opinion is that readers might jump on that trail and build a deep thread, which probably reduce the incentive to read any further by either skipping the middle to the end, ir simply ignore the rest.

Would be an interesting research to conduct if randomness can help based on say user karma. For cryto and security we know there are certain users seen as “goto”, so their opinions weigh much more and might end up being the top all the time. I’d like to see some “penalty” by promoting the less-popular users (not comment).

The target audience for GitMeet includes any developer who is working on an open source project and needs other contributors to fix bugs or work on subprojects within the repository. GitMeet provides popup tips to encourage users to contribute to projects they have joined and enables project creators to award "developer reputation" to developers who have provided helpful contributions to the project. Currently there are no payments involved with GitMeet, however, the main goal of the site is to encourage long term collaboration on a project.

There are services like strike that offer custodial lightning channels, and will aggregate and send onchain tx's: https://medium.com/@ACINQ/introducing-strike-a-stripe-like-a...

While the network has such low fees as today, there is no need to increase the blocksize. Increasing the blocksize (or time) effects scalability in epic ways -- ie: Ethereum requires at least 500GB SSD to run -- so the minimum cost of entry is at least $300. Meanwhile 10m/1MB blocks still runs on $20 RPis.

I am not against mods to consensus to increase the block size, but there are more critical problems like solving tx malleability and new tx format (segwit) that provide more value today.

I mostly agree with all that. Although in some areas like the rural US West, very secondary roads are pretty common. This becomes a bigger problem as more and more people depend on computers to tell them where to go without thinking much about it.

Of course, this isn't really a new problem. People have died following roads on paper maps that weren't suitable for, say, winter travel.

> It is not expected that updating npm will kill the complete system it is on...

I don't disagree with you at all on that. The reality is, however, that sometimes "shit happens".

I'm more of a sysadmin than a developer and I learned many, many years ago that even the smallest little updates can "go wrong" and take the rest of the system with it. After getting burned a few times, even a baby will learn to stop touching a hot stove.

Yes, but in that case your production servers would still be humming along just fine, no?
This seems to be the case with a lot of cryptocurrencies. They spread themselves too thin before they've even begun solving the core problems they need to solve. It would be enough to get a DAG-based distributed ledger/coin running and running well, but throw in all the extra nonsense and it's just a mess of poor prioritization.

Hmm... I did not mean for my reply to be an apology for IOTA, though reading it now I can easily see how it looks like it.

I'm not trying to rewrite history and say that "IOTA was never intended to be decentralized". I'm saying, as the article points out, that IOTA is effectively centralized, and the plan for moving to being decentralized is fatally and irretrievably flawed.

I also think the rhetoric about being a currency for the "Internet of Things" is a nonsensical claim at best. The fact that the coins does not deliver on anything it promises does not mean that it is worthless, because it still delivers on other things that people find useful.

I'm not sold on IOTA (I have no holdings myself) just as I am not sold on the other big centralized competitors (Ripple or Stellar), but I don't think it's significantly worse than either of those in terms of what it delivers.

LOSERS
I'm a little confused here. All trials have to be reported within 12 months of completion, and the law goes into full effect in February. So the tool gives the trials which have been overdue for some part of February?

The "US govt could have imposed fines" part seems to be way off too (unless maybe it's in thousands?). It says they can levy fines of $10k/day. Just clicking on one company, Bassett Healthcare, shows there is 1 trial overdue by 32 days. Only 22 days have elapsed in February (when it sounds like this portion of the law went into effect), so shouldn't that company be able to be fined at least 22*$10k=$220k? It has the total for all companies at $290k on the home page.

Maybe I'm misunderstanding something, but the tool doesn't have a lot of description that I could find.
To me it's like the junk food of software. Convenient, but it's hard to make an argument for it beyond that IMO.
Has anybody analysed how karma works for submissions that make the front page? It feels like there's either a rate limit on how much karma you can earn from a submission, or the amount of karma earned per upvote is inversely proportional to the number of upvotes, or something.

I've noticed that I earned 1 karma for 1 upvote for the first few upvotes, and also 1 karma for 1 upvote when the article's been off the front page for days but people are still reading and occasionally upvoting it. But in between it's definitely not a 1:1 - maybe more like 10:1 or even less.

It feels like there are probably some really interesting rules involved :)

It takes a while in the beginning, then you learn what works and what doesn't, which thankfully aligns fairly well with the community values as I see them. Here's a distillation of how I see them:

* Comment when you have something to contribute. The contribution can be small, even just adding your own experience. A "me too" comment will likely get downvoted. A "Me too. I often experience/feel this when..." will likely be left neutral or upvoted, depending on topic and content.

* Assume the other party in a discussion or argument is acting in good faith. Try to look for alternate interpretations for offensive or upsetting comments, and ask, if at all ambiguous. Even if it's clear the opinion is at odds with your own, don't condemn someone outright, ask why (and try to do so in a way that doesn't sound like you're setting them up).

* Tangents are okay. Responding to a particular comment but addressing the conversation is okay. Try to make it obvious when you are not addressing the person you replied to specifically. Context matters, especially for those that see the reply, and it's easy for them to assume it's supposed to be meant as a rebuttal to them when they've been seeing lots of rebuttals.

> other developed countries don't have so many homeless people

Not true.

Here are per-night homeless statistics from UN:

China has 2.6 million
Russia has 5 million
Ukraine 1 million
Germany 860,000
US has 554,000
...

But more profoundely, by homeless ratio, the US is not even close.

Germany, New Zealand, Czech Republic, Canada, the UK, Australia, Sweden, Luxembourg, Croatia, Bosnia, Russia, Peru France, Austria, the Netherlands, China and Greece -- ALL have higher homeless ratios than the United States. The US is in 33rd place for overall worldwide homelessness as a percentage of the population.

If your systems are designed for greater modularity, then it would be easier to replace board X version 2, in a vehicle that was manufactured when version 2 was the production-ready part, with a board X hardware version 8, with firmware 8.0-2.2 installed to emulate the part that was shipped with the vehicle.

The important thing is that identical inputs yield identical outputs. The rest of the vehicle doesn't care what's in the black box.

Then you wouldn't have to warehouse old, obsolete parts. You just have to warehouse old, obsolete embedded-software developers. That's probably cheaper if you have enough volume.

Also, if your company is still programming in assembly instead of a higher-level language, such as C, which has been available for 45 years now, I can safely say you are all hoist on your own petard. If you really want reliability, there's always Ada. You can't expect the 80196 to stick around forever.
> More simply, Facebook will change when users stop using it.

While I totally agree with this, I'm wondering where that tipping point would be with them.

They have (depending on who you believe) somewhere north of 200 million users with some estimates in the 500 million range. Does losing 100 million users impact them at all or their bottom line?

At what point do you think they would actually start changing? How much revenue would they have to lose before they started to make noticeable reforms?
Right, but most of them are getting landfilled at the worst, right? As I understand it, the majority of the garbage is coming from countries that have no commercial-scale waste disposal except ocean dumping.
Martin Shkreli wasn't targeted by the government for prosecution. Shkreli got the max sentence for a crime he committed because he was out spoken about how he was not remorseful his crimes, nor did he show any capacity to even understand the seriousness of his actions. He also encouraged others to commit crimes for him during his sentencing. Judicial discretion isn't always perfect, but enforcing the max on an obvious danger to society was the correct course of action in his case.
There is some serious amounts of cynicism and negativity in these comments. The article is an interesting introduction. The style is a little all over the place, but hardly worth closing it over.

I don't remember exactly what tool does this, but one package manager (can be homebrew but long time ago I used homebrew) warns users if you are running it as root, since it should install packages as the user.

I think npm could implement a similar strategy and educate the users how packages should really be installed.

Rubinstein makes the point (which I wholeheartedly agree with) that game theory is a lot like fables. They might help you interpret a certain situation in a certain way, but they have no value in actually predicting anything. I'm not sure how it will ever get there. If someone comes up with a goal function and actually makes predictions which work in the real world then yes, I would of course change my mind.

I share some of the criticisms already stated in other comments. The biggest offender here in my opinion is that it jumps to too many subjects. Trees as graphs, yes, but they are a whole subject of their own. This post should broken down in at least 4 or 5 posts. Moreover, its mixes vastly different concerns: byte level optimization is an interesting topic too, but it has nothing to do with graph per se.

On the positive side: relevant illustrations. I also liked that the code implementation is one that use explicit edges. Too often in books, it is either the adjacency matrix or the linked list ones. The former is inconvenient when you need to add a node, and the latter doesn't let you put weight on edge. So these "academic" implementations are not well suited for groking concept by playing with code.

I work a lot with graphs and there is a big value in having a general enough graph implementation. Last week I implemented a trie class with it, and this week a transducer. Both in two hours, debugging included. Other things such as serialization came from free from the library. Of course, that not optimal data structure, but it is fine for my use cases.

In your post, you don't use the fact that trees are graph to avoid duplicate code explanations, instead you explain it first for a tree, then details the graph one. It should be the reverse: how to use a graph implementation to create a tree. And then only if this implementation does not fit the memory or performance requirements of the app, rewrite a more specialized data structure.
