Designing Data-Intensive Applications [1] is a good book all around for creating application and management of the data that they provide including NoSQL.

There are a few services like https://digitaltipjar.com/faq

I'm looking for one that was a browser plugin - you click it every site you want to support (if that site opted in).

Then, your monthly spend eg. $5 is split between all of the sites you chose to support.

It let users commit to paying $N per month for their favorite sites, without having to calculate "should I give 1 or 10.." etc.

Anyone remember this? I saw it on a few webcomics
EFS is also slower than EBS, for I/O intensive workloads is not recommended.

A positive thing with EFS is that it can be shared across AZ while EBS needs to be snapshotted and then imported to the other AZ.
I built the site using Ruby on Rails, and ended up trying all the PDF libraries I could find. In the end I had to use six different libraries and tools to solve various problems with parsing or transforming PDFs.

The libraries I use are: pdf-reader [1], prawn [2], prawn-templates [3], origami [4], qpdf [5], and pdftk [6].

There's a new PDF library for Ruby called hexapdf [7], and it looks really promising. I think it might even be able to replace all six of these libraries, but it's released under the AGPL license, and commercial licenses are not available yet.

Could you please eliminate all the calls for webservers for fonts etc, I don't need those parties to know when I launch apps.
All true except that a transaction can have around 400 inputs per standard size transaction. You were assuming a single input. This means Bitcoin-based protocols can handle 8B users per month, which is more payments than the ACH handles per month.

The scaling of marginal vs. NRE costs (not to mention core-limited vs. pad-limited chip area) has put us in the somewhat odd situation that it's actually cheaper to crank out an SoC capable of running an emulator than it is to implement the thing you want in < 1% of the transistors.

I remember from university how solar is great for cheap and cheerful power applications, and fairly easy to set up. This platform is great idea! My 2 cents: can there also be a 'pitch-like' page or infographics explaining the basic configuration of solar power for newbies? This could encourage beginners to join in and share more, so there will be a nice diversity of simple hacks and ingenious projects.

I asked the HN community for feedback on using Swagger Codegen, AutoRest last year: https://news.ycombinator.com/item?id=12485310

They're essentially the same but written in different languages (Java vs C#/TypeScript).

Eventually we picked Swagger Codegen due to its active community and wide-range of supported languages/frameworks.
Awesome factoid!
> Not ranting or trolling, but in the vast majority of cases I've come across, PostgreSQL or even mySQL or SQLite would have been a better choice.

This is ranting.

I am a Postgres proponent but saying that PostgresSQL/mySQL/SQLite is the better choice in the vast majority of cases the parent has come across is reckless. The words were well chosen making the rant not that obvious.

There aren't good or bad DBs. Every DB has its strengths and respective trade-offs. As much I like Postgres, there so many use cases to use also other DBs and also NoSQL ones. I am not feeding the troll and starting reasoning why NoSQL can be terrific or SQL can be a big struggle, I am on both sides, both SQL and NoSQL have their place.

It's sad that a thread which is about learning NoSQL gets hijacked by a unrelated top comment opposing NoSQL.

OP makes the implicit assumption that all lightning network payment channels are p2p in which case the 20M users per month upper limit is true. From what I understand, the plan is to have a network of supernodes which settle on the blockchain. Users will interact with these nodes instead of true p2p. Lightning network opponents argue that these supernodes will become mini banks in some ways and will need to follow KYC norms. While it's possible to do p2p payment channels without interacting with any third party, the high transaction fees make it impractical. From the Lightning Network paper [0] :

> If all transactions using Bitcoin were conducted inside a network of micropayment channels, to enable 7 billion people to make two channels per year with unlimited transactions inside the channel, it would require 133 MB blocks (presuming 500 bytes per transaction and 52560 locks per year).

Notice the 2 channels per year. These 2 channels will be opened with a supernode (operated by eg- Coinbase, Gemini, Blockstream etc). I glanced through the document but they don't seem to acknowledge the requirement for these supernodes.

It's hard to cut through all the FUD, trolling, memes and propaganda to get to the meat of the debate, so I'm not too sure my understanding is accurate, feel free to correct me.

>The fact that you can't verify sources easily is not a symptom. It's a fundamental problem with the Internet today

Verifying sources is easier than ever. In the 80s it was a major time investment to verify anything. Today, if your source is available in written form - whether that's a newspaper, a research paper or a book - I can more likely than not start reading it within five minutes.

Fake news and trolling are much more a symptom of cheap and easy publishing, and the exposure they can get in today's attention economy. Outrage spreads faster than you can fact-check it
True, but there's a lot of people out there that have genuine knowledge about whatever the subject is, and if you wait a few days usually you'll be able to find multiple sources to verify or dismiss any claim.

The main problem is how much time and effort one is willing to invest into debunking the fake news stories? For the most of people answer is: not any, if possible. Even I will look at maybe 2-3 pages of google results and twitter feeds and give up, presume it's true. It's the same problem as computer security: it's all about the balance between the goal and convenience. It's just not convenient to double-check every fact that you read, you'd just do that whole day long or go crazy, so we choose to trust them...
Ha, thanks, fixed!
Completely subjective is too strong! Music is art but harmony is mathematical.
You put your public (and private if you want) pgp key on there. Then you make public posts on your social media signed with that key. This way, you show everyone that you own these accounts or websites or whatever.

If any of the proofs changes, it puts it on a timeline. If your account has a hard reset it notifies all your followers.

Basically its safeish key sharing in the modern world.
Persistent storage remains a complicated problem. Attaching volumes on the fly with docker volume abstraction works well enough for most cloud workloads, whether on-demand or spot, but it's still easy to run into problems.

This is leading to rapid progress in clustered/distributed filesystems and it's even built into the Linux kernel now with OrangeFS [1]. There are also commercial companies like Avere [2] who make filers that run on object storage with sophisticated caching to provide a fast networked but durable filesystem.

Kubernetes is also changing the game with container-native storage. This seems to be the most promising model for the future as K8S can take care of orchestrating all the complexities of replicas and stateful containers while storage is just another container-based service using whatever volumes are available to the nodes underneath. Portworx [3] is the great commercial option today with Rook and OpenEBS [4] catching up quickly.

RethinkDB handles joins just fine :)
And while we are talking about costs, make sure you check for unused WBA volumes frequently, as you still pay for them if they aren't attached/used - and sometimes a dev will create a provisioned iops drive and forget to delete it and you pay a lot for those volumes..
Probably for the same reason that predictive models are described as powered by “AI” instead of by “statistical learning”: Some terms are simply more in vogue even if they’re more vague.
A meaningful fraction of the problems remote workers face are related to the organization, communication habits, and workplace culture of the organization for which the worker works remotely.

For example, some great tool for video chat is only applicable if it is adopted as a default means of communication within the company. The remote worker typically cannot drive adoption. To the extent that they can, if it is only used to communicate with remote workers and not within the workplace the remote workers are less integrated into the ordinary flow of the company.
Author here, feedback is more than welcome. I tried to be very detailed and explain how the whole thing works. There will be more posts about webpack/react in near future.
Thanks for straightening out my confusion!
NoSQL is a great fit for OLAP-type systems where there's tons of high volume writes, eventual consistency (or BASE in general) is good enough, strict schema is not enforced and the consumer - data scientist or a customer service rep etc is not affected too much if they have to wait a few extra seconds for the search results to come back.
Intel’s CPUs are such and impressive and obvious showcase of the evolution of a product. The early chips like the 4004 are downright primitive, and each product leapfroggged and obsoleted the one before it, right up until the Pentium IV.

Each chip brought a huge new feature or performance gain. It’s also amazing how fast they went from a hobbyist chip to a full-feature chip that could do anything the rest of the market could.
IMF head: I can not afford investing in Bitcoin
So thought experiment: the incentive to stay on L2 is anonymity & lower transaction fees. Therefore as usage goes up transaction fees will raise but more will be pushed to L2 in order to avoid those fees, & in effect reducing them

So let's say things have exploded: transaction fees are twice my salary. If I get stiffed on L2 I'll have to pay more in fees than my salary. So my recourse will be to sue my employer into paying the transaction fee

Same happened to me. I "lost" my all my credit. It was not promotional, but something I had paid. They informed me on March 31th that I wouldn't be able to use that credit after May 1st. :-(
P.S. They had no expiration policy in place when I added the credit.

Now I am happy with AWS.
They probably didn't even realize they were fixing it. That happens sometimes.
Mt. Gox was a centralised custodian. Layer 2 systems like Lightning Network are not, because they can't run away with your money. If they try to cheat, you can always withdraw your money.
It's might become harder than you think.

Especially modern stuff. I've been talking with a lot of hobbyist drone owners lately and several folks are working on fascinating projects using a fleet of semi-autonomous lightweight fixed wing and quad drones along with modern autonomous aircraft techniques.

These things are small (you could hold them one handed on a crowded bus), fast (even the quads break 140mph), can be quiet (especially the fixed wings) and have cellphones.

One of the projects I saw was proving that an automated drone network could create a full coverage, high resolution video coverage of a parking lot even with drones having to leave the site to get fresh batteries.

They're working for a team that has a DARPA grant, so...
There's a mechanism exactly for this purpouse in Linux: pivot_root. It's used in the standard boot process to switch from the initrd (initial ramdisk) environment to the real system root.

ec2-spotter classic uses this, but you can also make a pivoting AMI of your favourite Linux distribution.

One thing to watch out for is how to keep the OS automatic kernel updates working. AMIs are rarely updated and you're going to have a "damn vulnerable linux" if you don't get the updates just after booting a new image.
Watson is probably a capability overreach thanks to some marketing gurus at IBM.

If you think about complex games like Chess, or Mario, or Find Waldo, and then think about the abstractions we use to reason about very complex topics, they aren't terribly different. Games like Cities:Skylines are being looked at seriously for modeling civic infrastructure.

If we can train a system to reason about things using the abstractions we also use, and they're as successful as a human is using those abstractions (or better), then we've "won" in a sense.

Find Waldo isn't too far removed from "find the right screw in the parts bin" at a factory.
KolibriOS is the fork of the 32-bit version of MenuetOS, which is already open source, so they're both valid for that matter.
I'm really confused. Is this intended as a programmer's tool? Or as an end user tool?

If I understand it, create an HTML form, submit to server, spit back PDF. This has been built into ColdFusion for about a decade, and it is trivial. [and I assume other server side software can do the same thing].

Aside from that, the bulk of the PDF Forms I download these days can already be filled out with Acrobat. I'm not sure what benefit you're offering me in time savings.
Seems like it wasn't great even before any accident.

It is mentioned under the 8086.

Intel also produced the 8088 around the same time. This processor was based on the 8086, but with half of the data bus disabled. This loss in bandwidth hurt performance, but as it still had access to up to 1MB of RAM and ran at higher frequencies, it was faster than Intel's previous eight-bit processors.
> EXDAMS [...] a thought experiment

Ah, good point.

> "generally practical for two or three decades" [...] the first practical products

I was thinking of "we now know how to do this" (snapshot and replay (and input log)), rather than "and it's a product".

Which seems sometimes valid, and sometimes not. We know how to make a 4K/eye VR HMD with existing parts, and it's simply a market failure that one's not on my desk. But for other things, "know how to do it, sort of, in a lab" and "know how to do it, practically, for real" can be greatly separated in time and effort.

Agreed. If you approach QM as

Ask HN: When do posts get flagged?
Recently, I made a comment in the thread 'Our minds can be hijacked': tech insiders who fear a smartphone dystopia' ( https://news.ycombinator.com/item?id=15421704 ).

Shortly after, my comment was flagged! I thought my comment to be very polite, so I was quite surprised by this.
Could anyone tell me what the flagging criteria are in general, or more specifically: why my comment was flagged? This was my comment:

Just because I understand it differently from you doesn't mean I don't understand it.

And I should be clear that I'm really lamenting about something bigger, which is the tendency for "always defect" strategies to get normalized as "smart" in our collective economy's various prisoners' dilemmas. We suffer collectively because of it.

More concretely: right now because of how cheap, bad quality mortgages artificially inflated housing prices around 2008, and again today, and because of the stagnancy of wages, most people I know cannot afford to buy or rent without compromising their well-being significantly.

If "cheap" mortgages weren't so rampant, how would property values even have been able to inflate like they did? They wouldn't... it'd be a totally different market. I think home values would be much closer to their physical value, reflecting the state that they're in rather than some abstract, speculative potential value. There would be less incentive for speculators to hold on to them for the sake of "investing" and more reason for people to hold on to them for the sake of living in them.

Just where does that money circulate back to? Right now it circulates back to the most wealthy, those who this article is talking about, those who are usurping their feudal lordships right now.

Where I live, there is a housing trust that bars people from buying its houses to rent them, and protects houses from bubbles. When people want to sell the houses, they have to sell them through the trust, where the amount they could lose or gain from market fluctuations alone is capped at 25%. If they made improvements on the house, they are able to sell it at a higher value. The houses are significantly less than market value. And are much higher quality than rental properties.

It's basically the Nobel Progressive-Left Prize now.

Bob Widlar, who started at Fairchild, was my childhood hero. I literally last week built a power supply with a µA723, a 1967 Fairchild originated part (although mine was an SGS Thompson clone) because it's still pretty damn well one of the best parts out there even after 50 years. Good times. I wish I was born a lot earlier than I was if I'm honest.

Bob Widlar, for reference, was quite a character: http://www.electronicdesign.com/analog/what-s-all-widlar-stu...

"...if humans do have a big capacity for peace shouldn’t we expect to find more accomplished people on this list?"

Go look at the list of Nobel Peace prize winners:

https://en.wikipedia.org/wiki/List_of_Nobel_Peace_Prize_laur...

Some of the winners probably didn't deserve the prize and are now disappointing to see on this list (e.g. Obama or Arafat).

Some of the winners are symbols of inspiration rather than people who have accomplished much themselves (e.g. Malala Yousafzai).

However, there are a lot of highly accomplished people on this list who have made a huge impact on the world. Many of them just aren't as famous as some of the disappointments.

Alfred Nobel was a merchant of death. The fact that people striving for peace now feel honored by a Nobel Prize is deeply ironic, but perhaps this also shows that, even among those of us with the most blood on our hands, there exists the yearning for a more peaceful future.

There are many things the author didn't think about. With Segregated Witness, the signatures don't need to be part of the 1MB block. Also for multi-sig we will be using aggregatable Schnorr signatures, so multi-sig won't take that much space. Still, the cost of an on-blockchain transaction will probably go up to $1000-10000 in current US dollars, so I believe even having an on-chain transaction will get too expensive for most people. For the short term lightning should be a relief though until the community can come up with the next scaling solutions (after implementing Mimblewimble as well)
