> There are a lot of distributed systems books I love, but I haven't found an accessible introduction I particularly like yet.

I'd highly recommend Martin Kleppmann's Desgining Data Intensive Applications [0] as an introductory book on distributed systems.

> Here's Jaso Sorenson describing the design of DynamoDB

For the uninitiated, Jaso played a key role in S3's evolution and was one of S3's founding engineers along with the then CTO and now Distinguished Eng, Alan Vermeulen (who's probably Jeff Dean of Amazon), who btw is an expert speaker. Such a shame folks outside of Amazon don't get to see his numerous talks. Absolute legends.

> Colm MacCarthaigh talking about some principles for building control planes.

Jaso also built "one of the most complex distributed systems ever built at AWS", what then later formed inspiration for AWS HyperPlane and the NetworkLoadBalancer by a team led by Colm, who inturn, was a founding eng with Route53 (first-ever 100% uptime public service at AWS?), VPC, and CloudFront among other very fancy security things.

> I've (Marc Brooker) been doing this stuff for 15 years in one way or another, and still feel like I'm scratching the surface.

Well, he's being humble here. Marc's internal wiki pages on various designs he's come up with over the years for AWS are absolute gold mines, in that they explain his thought process, his experimentation, and his research with existing publications. Along with Colm (and a few others), he's is a prolific speaker internally at AWS with some of his talks ranked in the top 10 consistently. His recent contributions with EC2/EBS and Lambda mean he's worked with the largest and most complicated distributed systems there ever has been at AWS (imo, of course).

There are others like Eric Brandwine (Security), James Hamilton (Data Centers), Peter Vosshall (Silk, EC2, and Architecture), Becky Weiss (VPC and Lambda), David Yancek (IoT, NoSQL), Andrew Certain (DB), Tim Rath (DB), Stefano Stefani (DB, Warehouse, AI), Brad M (S3), Nafea B (Hardware), MSW (EC2/OS), A Ligouri (EC2/OS), Hall Cary (Builder Tools), Marvin T (Kinesis) et al who don't get a mention in the blog post but have been every bit gigantic in their contributions at AWS since forever. The recent recruits at the top rungs of eng at AWS have considerable pedigree coming in, as well. Exciting times, for sure.

I wish they'd release those internal videos (and CoEs) on a case-to-case basis to public. That'd go a long way in contributing to the distributed systems literature... apart from resuming to write blogs and papers abt their systems [1] like the NetEng/Route53 team once did.

Yeah, being a western currency, Libra competes more with RMB than with Euros or Dollars. It's more what the CFP franc is to Euros than an anti-Dollar. If the power grows too big, it may get nationalized like how the BEIC got nationalized.

the US job market for coders is kind of saturated anyway, and given the extreme selectivity tech companies apply to job applicants, avoiding coding might be a good thing for people in that particular sub-population. i mean it will probably save ex-cons a lot of heartache. our beloved tech employers are likely to discriminate against ex-cons just like they do other minorities and protected classes. what is the point of raising an ex-con's hopes of getting a coding job? the tech companies are going to find some reason or other to reject them anyway.

A few dozen sensors can go a long way, for example a municipality can find that a particular pipe is consistently pushing 100gpm, despite serving residential customers that don't normally have that kind of even usage. This implys a leak on that section of pipe, making a root cause analysis (and shutting off just the worst leaks in the system, rather than the whole town) much easier to do.
At least in the US, not sure about the EU, but unless your profession is explicitly exempt salaried employees are still owed overtime. Unless a job explicitly states the number of hours an employee is to work it's assumed it's 40 hours.

Of course there are exceptions, such as programmers.

I'm the wrong guy to answer this but I believe the ports are available to one pipeline, so no independent pipelines, but instructions behind the 'head' can hop over the head if the head is stalled, if there are execution units free. Instructions can get reordered, over quite a wide window, something like 200 instructions (look up the reorder buffer, ROB, although there's another windows which affects this, something to do with retiring instructions).

<https://en.wikipedia.org/wiki/Re-order_buffer>

Come to think of it, I don't know how the ports are used. I am entirely unqualified to answer this question :)

Ouch. I’m pretty comfortable asserting that Equifax most certainly did not have “pillars in the field” on staff. Not to say they were all incompetent, but that’s a Trump-level exaggeration. This former Equifax “countermeasures manager” is apparently woefully unqualified for any security job. Not because they were breached, but just because of how out of touch he is with every statement he makes.
It's about 1000x better than "Designing Distributed Systems" which is basically just a book about Kubernetes. (Should have known, since its written by Brendan Burns).
That's an interesting thought. I will say that non-memorable is not the same as non-important. "Did I drive under a bridge" isn't the same as "did I leave the oven turned on" or "did I lock the front door".

Introduction to Nintendo 64 Programming (1999)
It is unlikely that you will need to sit in a bank and fill out forms to get a card. You will have no more hoops to go through than in-game tokens.

Which makes me wonder, why haven't there been in-game tokens made universal yet? I don't do Facebook but didn't they once have a large Zynga game thing on the go, very much tied into the platform?

A monopoly on a virtual currency should have happened by now, one that only buys stuff in games, unlocking features etc., transferable to mates.

If this had happened then it would not be that much of a leap to make the virtual token be handy for real world things. Crypto-nonsense would not be needed, it could just be like a classic in-game token.

If the tokens can be cashed out to hard currency great. But some people might never need to do that. They could buy music and apps with mummy and daddy doing the top ups.
Lagrange points are not points. They are areas of space. This a typical "spherical chickens" problem. They are mathematical points when calculated from other mathematical points. The earth is not a point, nor is the moon or any other body. Add in the effects of distant bodies (jupiter et al) and the Lagrange "point" is best thought of as a Lagrange area.

A spacecraft will not gravitate to the center of the area, nor is a spacecraft guaranteed to stay in the area naturally. It will be nudged out eventually. So the normal approach is for spacecraft or orbit the area, pretending it is a point when it isn't. This is still an unstable orbit and requires station keeping.

Station keeping in deep space is hard. Without easy reference to earth locations (no gps) it is hard to remotely determine exactly where the satellite actually is. So you need local, on-orbit, sensors to track stars and the sun. But it is still going to take fuel.

If L points were points, If objects could be caught and stay there, the rocks would by now have bunched together into lagrange moons. Those moons would create new L points between them and other bodies, creating layers of new perturbations, until the system breaks down into chaos. These aren't "parking places in space".
“When you do business with banks or other lending institutions, you are explicitly granting them the right to exchange your payment information with other institutions and CRAs.”

It’s not like we have a choice. Every such business participates. I suppose it’s possible to avoid credit reporting by not having a bank account or utilities or a job, but that’s not a very practical way for most people to live.

I don’t see the point in blaming banks instead of credit reporting agencies. They’re all part of one big system that works together. All parts of the system make it the way it is. It’s no more sensible to try to blame an individual component of the system than it is to debate whether to blame a murderer’s hands or his legs.

In this case, I think the concern goes:

FB exerts increasing control over, and insight into, financial transactions. Alongside excessive insight into most other aspects of personal lives. The result becomes the sort of MegaCorp that cyberpunk novels are built off of. Except, you know... I don't think William Gibson ever expected the future megacorp to have sprung up from an undergrad pivoting his Hot or Not rip-off.
> I think most countries criticizing this don’t have an active organ harvesting and internment camp operation against ethnic and religious groups, though.

That's true, though I have a feeling the "guests" at the US black sites would've preferred to be transferred to Chinese Gulags. Were Libya, Iraq or Syria drunk driving accidents? I suppose we might disagree here.

Everybody always claims they do the terrible things they commit to make the world a better place tomorrow. Who you support in their doings and who you call a villain is up to you. I suppose if HN was created in China and majority Chinese, most here would argue differently.
Crypto in this case does mean cryptographic currency, and it is indeed part of an Cypherpunks wet dream, which is a movement since the 80s to 90s[0][1], and Bitcoin was largely enabled by people of this movement[2][3]. They basically strive to build society with cryptographic methods.

Cyberpunk on the other hand is just a science-fiction genre, which mostly play in futuristic orwellian dystopias and people like to draw comparisons to them.

A median US household receives employer subsidized health care. In many cases, those plans are high-deductible and thus inadequate, because it could still mean having personal expenses to the tune of $7000-8000 a year of post-tax dollars.

This is also being done at the expense of those who are not eligible for subsidies on the Health Care marketplace, but do not receive employer subsidized health care.
Nation in nation state is pretty recent addition and already dying off (fortunately), but the state owing allegiance to its citizens (ever imperfect) is better than slide back to feudal-authoritarian corporation that is in no way on the hook for anything towards the common man.

My mistake then. I did not intend to try and be so precise. I was thinking loosely. I have a very simple autodiff tool hand rolled (in Python) here to play with. I raise 0 to a negative exponent in the gradient of the cube root at 0. I do not get a NAN. Strictly speaking I get this:

"ZeroDivisionError: 0.0 cannot be raised to a negative power"

Is that satisfying? I do not claim anything more specific here. Sorry to be imprecise.
You left out: It's a small scale disaster for an already poor community because businesses had to shut down for several days and cut employee hours. The town seemingly doesn't know how to recover from the financial blow.
I don't know the right terminology, but maybe it's a "power" thing.

For instance, if it's two people at the same power level, it gets complicated. If it's someone at a high power level defending someone at a lower power level, it's ok.

So defending handicapped people, or kids, or puppies is ok.

I've heard stories of people breaking a car window to get a kid or puppy out, and that's pretty much universally accepted.

But defending other people at the same level as yourself might be a harder sell.

I remember reading that the difference between police and citizens is that police can give out misdemeanor tickets.

And people have to adhere to the law, but sometimes they don't.

Again, police are people. Sure they're supposed to follow the rules. But sometimes they don't.

What makes police better is that they at least have the training. So they have the knowledge of how to do it right. Whether or not they do it right in fact is an entirely separate issue.

This is a disgrace. The idea that someone is going to be a menace to prison computer systems because they read a few books is really laughable and betrays such a thorough ignorance of how these things work.

No one cares about prisons because it’s not an issue that affects most of us in any way and prisoners aren’t a powerful interest group.

The absurdities of bureaucracy are allowed to fester without checks. What does the person in charge of approving books, who is probably ignorant of technology themselves, gain from allowing a book? Nothing. What do they lose if allowing a particular book leads to problems? Potentially a lot. So they’ll only allow only the safest material for which their judgment could never possibly get questioned.

I don’t think there’s a conspiracy to keep prisoners uneducated and likely to come back to prison. There’s just no reason to for the people in charge to do better.

I don’t know how feasible it is, but if we’re going to have private prisons, maybe they should be rewarded when prisoners successfully reintegrate after their release.

You need to put the blame where it lies. CRAs simply aggregate data. They aren't the ones that grant credit. If someone opens a CC in your name, it wasn't the CRA that did it. So blame the bank or CC company for not sufficiently verifying identity.

Think about how the process works. A criminal goes online and applies for a CC, using your personal information. The CC company goes to a CRA to check credit worthiness. The CRA says "Sure, mikeash is a responsible person who pays his debts on time". The CC company says "Great!" and hands the criminal an account in your name. It's the CC company that didn't do the due diligence to verify that it was really you.

However, since the Equifax hack and the resulting backlash, the CRAs have started offering much greater consumer control to consumers. Equifax has a free service that allows you to keep your information locked and actually notify you in real time when a request is made, that you can block or allow as you wish. Basically 2FA for credit. If the other CRAs don't have that service, they soon will.

I've learned this fact in my neuropsychology class from Prof. Dr. Erik Scherder. He is nowadays semi-famous in The Netherlands even and spreads this message as loud and as far as he can.

The thing that annoys me about research like this is: it may be true, but I don't feel it. So to what extent is it really helpful?

That is until I had an accidental yet natural experiment that lasted for two weeks.

For two weeks I cycled every odd day to my work and I went to my work by metro every even day. It happened to rain every even day (and sometimes I decided to go cycling anyway on odd days, despite it raining).

At some point, after about a week, I started noticing upon reflection that I felt much better at work whenever I cycled. This reflection wasn't planned, I simply wondered why I felt not as horrible as I usually do in similar circumstances -- I was severely sleep deprived when I was reflecting on this. Since I wasn't purposefully conducting an experiment and this wasn't on my mind, I figured this showed the true strength of the effect. The second week I started zooming in on this difference and really noticed it well.

I estimate that I was about 20% cognitively more performant and 20% more emotionally stable. It didn't matter whether I had sever sleep deprivation or not. It always felt like I was about 20% better.

So, if you want to experience it yourself. Cycle on odd days (for about 20-30 minutes) and go to the metro on even days. Within 2 weeks you should have noticed a difference.
perf-tools are my favorite. The overhead is negligible, and thus any metrics you gather are very accurate. Valgrind is rarely useful, considering the execution time disadvantage.
