MapReduce as a paradigm and technology was popular about a decade ago and then died shortly after in favour of Hive, Spark etc.

Pretty confident that not a single developer anywhere in this world would be first thinking of MapReduce. Just like they wouldn't jump straight to Cobol.
You can easily run a workload with 20tb/day on a single thread ripper.

My last contract we wrote a c tool that did dsp on 10tb/day data with a latency of 50 microseconds. We are using less than 10% of the CPU on that.
WSU also recently came out with the delicious Cosmic Crisp apple. https://en.wikipedia.org/wiki/Cosmic_Crisp
Wouldn’t we be observing the outer 30% (or 1%) though? From the diagram on the page you linked it seems that the granules in the photo exist in the photosphere, where convection is the dominant mode of energy transfer. That said, none of the conduction could happen without radiation further inside.
No but I'm going to say that archaic humans, once they acquired that knowledge, probably passed it on religiously. It's literally the single most important discovery in the history of mankind.
Whatever else may be in various vape juices, nicotine itself is about as harmful as caffeine. A mild stimulant, addictive, (as far as we know) harmless in normal doses, and will kill you instantly if you get a few grams at once. IIRC caffeine isn't a good pesticide tho, whereas nicotine is great, so YMMV if you're an aphid.
Comments moved to https://news.ycombinator.com/item?id=22188800. That submission is currently at #1 on the front page, so it's likely to keep the discussion going for longer.
Reminds me a lot of how the first version of objective-C was implemented
I fully agree, but our business need was to stream log files (e.g. tail -f) and to search for snippets in them and to produce statistic counters (e.g. |grep|wc)

While I can imagine situations where ElasticSearch is the best solution, I have seen it mostly used in situations that would be better served with simple command-line tools, similar to what the author demonstrated with awk vs. Hadoop.
The've also cut the electricity to unions that they don't agree with. That doesn't seem so democratic does it.
We've merged that discussion hither.
You can, but don't forget, that you have to by miners, get cheap electricity and if you want a result, you have to have major share of hash power. Other way you will not be able to include transactions if majority pools will not agree to include them too.

Don't forget, that this pool should be part of criminal organizacion because I don't think any businessman will invest hundreds of millions of dollars and risk his mining operations shut down.
Yeah the city sets prices based on the square footage being renovated and:

> "The valuation data is based on information provided by a variety of sources, including without limitation, local contractors, design professionals, cost estimators or nationally published construction cost data books or websites."

https://sfdbi.org/sites/default/files/Cost%20Schedule_0.pdf

So it looks like SF figures $98/sq ft. + $10,561 for the kitchen remodel and $8/sq ft. for reroofing, etc.

In either case, even if it did cost 3-4x that permit amount, we'd be talking about 10x the median household income instead of 12x over those 5 years. Still just a crazy situation.
The same argument is true of WiFi over a network cable. Depends on the packet loss on the way down. You also potentially might have to send more data for security reasons too.

Also, if the satellite is halfway between them (without taking the curvature of the earth into account, assuming a flat earth and the signal only goes through one satellite), the signal still has to travel 5590 km to cross the Atlantic (at almost c). Probably a solvable problem but not a trivial one.
As a possible middle-ground: I'm using Graylog with a lot of success, but my log volumes are rather modest (medium sized corporate network switches/routers/firewalls/servers log aggregation and processing)
Apple Stores in China Closes Down After Coronavirus Outbreak
Coronavirus Outbreak Is the Best Thing to Ever Happen to Corona Beer's Brand
I pick up smoking a few in a gap of a few months. Then I feel guilty and stop for a few months. I have been smoking about 50 cigs year. Truth is I don't think I can really quit. Forget addiction, I just like it that much. It is so much fun. I remember my first cig. It was so much fun. That's all it took
Notebooks also inline visualizations more naturally than the repl, which makes them really nice for the data analysis workflow.
There are a handful of reasons I’ve been farting around with SBCs, but one of them is an informational website for an outdoor attraction with no good spot to string power.

Not quite how this article meant solar-powered, but still some useful food for thought.
Not a meaningful amount of capital though.
The cameras are also a great deterrent just for being there. After installing some on our vacation house, our gardener told us there's almost never junk flyers anymore.
I interpret climate inaction not as science ineptitude, but as defecting in a prisoners dilemma sense.

The high capita emitters (AU/US/CA/NZ) are refusing to slow down economic growth (each country has to slow down to different degrees, depending on their existing energy mix), and are relying on other nations to make progress.

Rich countries will adapt. Poor country may not have the resources to do this, and thus climate inaction is an inequality issue, not just a scientific issue.

Politicians respond to votes and slowing economic growth is not popular.

Either rich countries will willingly sacrifice growth to help the poor of the world (not going to happen), or we encourage international cooperation. This is what's happening (Paris, Kyoto), albeit with defectors who need to be punished.
GNU lambdas are incredibly evil. In order for lambdas to capture their environment and yet still be available as a function pointer, the compiler makes the stack executable and stores the trampoline code on the stack.

C++ lambdas don't suffer from this problem.
One common query was to check the FTP server on our side for access from a customer server, so that we can help with troubleshooting as to why they couldn't connect. Turns out, in many cases less-technical customers mistyped the hostname or left out the .com at the end.

tail -n 10000 /var/log/ftp.log | grep -i $CUSTOMER_IP | tail -n 5
The idea here is that stock prices are determined by the people who want to pay for that stock. It's not a function of the company's operational success.

What you are saying is circular reasoning, you essentially say that company performance matter because many people think that is should matter. There's no causality relationship here, essentially people think that matters because other people thing that matters.
Possibly found a major security issue and just don't want to spend the effort to fix it?
The issues here are simply too complicated for juries to decide--particularly the amounts of money.

If Apple was simply using devices it purchased from Broadcom, Broadcom should be responsible for all the damages.
If you paid cash, in virtually every case you'd pay exactly the same price because most merchants don't provide cash discounts. If your merchant does provide a cash discount, I would suggest taking advantage of it. But if they don't provide a cash discount, you're still paying that 2% margin anyway without receiving any benefit from it.

Likewise, except for small businesses whose owners don't actually price in the cost of their own time and labor, it's not entirely obvious to me that the cost of accepting credit card payments actually is any more expensive than the cost of handling cash, which is probably why cash discounts are rare. The main exception to that seems to be gas stations (which usually have a lower price for debit cards and not straight cash), except even in that case, I get an even bigger discount by using Costco's gas station, which doesn't have any such discount. You do address this point...

> > Once upon a time, it was beneficial for a merchant to accept credit cards, it lowered their costs for handling cash, which meant they saved money and the 2% cost for each transaction was reasonable. In a world where everyone is using credit cards for every purchase, that 2% is essentially a tax instead.

That makes no sense. If the cost of receiving credit card transactions is 2%, that doesn't imply that the cost of receiving any other kind of transaction is 0%. If there's no cash discount, the difference in cost to the consumer is zero anyway. But the difference in cost to the merchant isn't 2% either, because if they accepted a different form of payment, the difference in cost would be 2% minus the cost of accepting that different form of payment. (And if they didn't accept any form of payment at all, the cost would effectively be 100% because there would be no sales). In a world where credit card sales are ubiquitous, if anything, credit cards become a better deal for merchants because there's less economy of scale for cash-handling services.

All in all, I would even suspect there are instances where credit card rewards end up providing a net positive to a sufficiently devoted cardholder simply because most people are not going to expend the time and effort necessary to maximize their credit card rewards. It's just like Vegas in that sense--while it's true that "the house always wins", casinos will also comp you rooms and drinks, and there are documented instances in which you would expect to be better off playing video poker or blackjack for long enough to get a free room (assuming perfect play, which means memorizing a small decision tree). Why is this possible? Because the vast majority of people don't play perfect blackjack or video poker. Businesses plan for average-case expected customer behavior and not best-case (or worst-case from their perspective).
Tried and it was horribly slow. We add about 5TB of logs per day, and the ES index wasn't able to keep up, despite having 256 GB RAM and 2x Intel Xeon 6-core
A lot of people smoke in Portland, Oregon and Oslo, Norway. At least that is my impression as I don’t have any facts or figures. But of the people I do see smoking, a significant portion of them are young. Another interesting to me observation is the way cigarettes smoke smells in Portland vs. Oslo. I don’t smoke, and don’t enjoy the smell and damage it does to the environment. If only people could properly dispose of their cigarette butts and snooze packets.
I was looking for a list of the Maynard's laws mentioned in the article. Turns out the author is called Maynard and he just made them up on the spot.
Wawa data breach: Hacker is selling 30M credit cards on the dark web
I once did a motorcycle trip across Canada when I was young, poor, and eager to ride motorcycles. One night my plan was to make it to my friend's place in Montreal, but it got late and I was still in Ontario. Ontario is long. It's not easy to appreciate how long Ontario is. It was dark and I was tired, but I wasn't seeing any campgrounds and didn't want to spend money on a motel. So I kept pushing, as one does at that age, thinking I'd simply will myself to stay awake.

Suddenly I startled awake with the awareness that I had fallen asleep and had been riding while asleep (presumably just for a second or two). What shocked me awake was realizing that these lines of Coleridge's poem had been playing in my head:

Softly and smoothly went the ship,
Moved onward from beneath.

I checked into the next motel.
Gateway Timeout Error
There are many HTTP status codes sends to the users and one of them is 504 gateway timeout error and this error occurs when your request is unable to complete by servers. When you visit any site then the site grants your request and sends it to web servers and if your request is unable to complete then the server sends back the error to you.
> But not when printing to stdio.h text streams; \n turns into the right line ending.

Only on some, but not all, compilers. I got varying behaviour until I went ahead and did it myself.
https://www.cuesinfo.com/blog/504-gateway-timeout-error/
We have 5TB per day, which may or may not break Graylog. Before evaluating ES, we used Logstash, but that couldn't keep up at around 2TB+ per day.
The nice thing about LEO is that everything deorbits automatically.
Out of my personal go-to c++ libs, the only ones I missed are the stb libraries (https://github.com/nothings/stb/, in particular the image ones are very popular) and maybe ImGui, but that might be too niche.

Also I would love to have a nice c++ lib for uuids. It's in boost of course.. but well that's boost. Outside of that there is one, but it requires GSL.
Best job recruiting post ever grateful dead inspired maybe?
I love the simple and lightweight interface, but everything is hard to discover.

Sourcehut? Sounds great- I'd love to replace my Gogs/gitlab instance with something more lightweight. Let's download the source and run it.
I guess click on "git" on https://git.sr.ht/? Wait that's where I already am with no indication that that is the selected tab.
Ok maybe the link for sourcehut? https://sourcehut.org/
Cool. There's some links about pricing, ignore that and click on "100% free and open source software"
Now I am just at a list of what appears to be about 20 repos, all with helpful names like sr.ht-apkbuilds.

I can tell that this person has put a ton of work into making something that is probably fantastic, but it is really all presented in an undiscoverable way. I still have no idea what language this project is written in, how to deploy or maintain it.

I assume https://git.sr.ht/~sircmpwn/git.sr.ht might be what I want, but it still looks like the inscrutable mess that reminds me of hgweb. There's not even a readme on the first page, let alone the source or anything useful. There's a link to https://man.sr.ht/git.sr.ht/installation.md. Which looks like it might be what I want, but I guess I'm old and at this point I've lost interest.

I'm definitely being crotchety, but I wish this information was organized in a more useful way. I can tell Drew has put a lot of time into it, but I don't feel like it is being shared in an effective way. And I would definitely never pay for software like this. Please someone tell me I'm crazy and this UI makes perfect sense to them.
Might be worth taking a look at ripgrep[1].

You can also do XMPP over HTTP (long-polling aka bosh, or websockets). If people really want to add a layer, it is doable :)
I'm working to implement alerts via calendar events right now actually. I already have alerts based on web push, but frankly the web push notifications API sucks. You only get the notifications on one device, they are delayed by random amounts of time (hours in some cases), the UI for enabling them is spammy and lame, and Safari doesn't support them.

Calendar events suck too because there's no standard way to add an event to a system calendar across platforms. Even the same browser on different platforms acts differently.
Not gonna put a single dent in FAANG. Humans love centralization, we don't like to have things scattered around. It's in our nature, hence there will always be FAANG companies that will have more data than everyone else.

Best case scenario EU will have some centralization on their own where people will come and give data there which will achieve nothing more than having EU joining FAANG club.

Worse case scenario? EU will implement same stuff like China with their great firewall continuing the current trend to have Splinternet instead of Internet
I guess I would never buy a PIR sensor for $50. You can get them for $6, so that's what I anchor off of. Not that I'd expect your product to be close to $6, but $50 PIR sensors are way overpriced, so I wouldn't ever think to compare to those.

Despite heavily automating my own home and being the person who sets everything up for my extended family, it seems I'm probably not your target market. Sounds like you have some cool tech though!
There with you, 17 years - , clean for 1.5 years.

Sounds good! Chargebee and Heroku are the 2 paid services that have saved us the most time. I'm a champion of your service.

While I have your attention, some unsolicited feedback: Chargebee's core is great (and that's what we care most about), but a lot of the UX is kind of whacky and the new redesign of the Customer Portal and Signout flow was also a bit whacky and we won't be upgrading.

Last thing, small pet-peeve of mine: password rotation is annoying and is an outdated practice. Both Microsoft[1] and the FTC[2] are encouraging people to stop using it. It ends up wasting my time because I can never remember what I've incremented the last digit to (I now track it in a file). I've given your support that feedback, but doubt anything will happen unless you give the order.

Thanks to this comment I noticed mine has a hospital:

bannerhealth.com (8)

The portal where I access my records is on a third-party vendor's domain and this is likely just from Like buttons on their public site. But I wouldn't be surprised to see the name of the specialist I saw (just to look up their phone number) or a condition they treated (the portal links to articles there) in those 8 entries. Haven't bothered to download my entire history just to see...yet.

I smoked when drinking (maybe 2-3 packs/week) throughout my 20s and if smoking wasn't a death wish I still would. I enjoyed smoking and I enjoyed the camaraderie of those who would escape outside the party or pub to escape the noise and have a chat and a smoke.

It's been a long time since I've smoked. I've lost people close to me and will soon lose another due to lung cancer or emphysema. Smoking sucks, but I do miss those quite moments outside in the cool air with a cigarette.
Uh... This is serious landmine... I suggest author to change this.
> SpaceX will be pressured by the governments in the jurisdictions where their staff reside (where their physical threats of enforcement can be carried out) to selectively censor/blackout or otherwise wiretap use of the system, ostensibly for military purposes, in another tragic case of stupid, outdated nationalistic thinking trying to force its way into outer space and cyberspace. They will comply, silently and without fanfare, as all of the other telecommunications carriers have, excepting with great recognition the brave Joseph Nacchio, because they don’t want to suffer the same fate he did.

Anyone remember the SWANsat project,[0] which was going to use a VPN service[1] as its client gateway? They called it "SWANSAT LIBERTY™ Suite".

Somehow, I doubt that Starlink has anything like that in mind. But still, one could use it with any anonymity network, unless that was somehow blocked.

TLDR; it’s about software locks, using locks in Go as the exemplar.

Validating idea: group meditation using Zoom or Hangout
Hello Hackers,

I am practicing meditation since last 10 years. In my experiece, I firmly beleive meditation works best when done in group.

I am planning to build a solution where anyone can join group meditation using their phone anonymously.

But for validating the idea, I am going to use Zoom and Hangout to organise digital group meditation.

Perhaps with CCS but that is yet to be proven.
This particular code isn't about the post. It's about Bournegol, which doesn't actually exist anymore, and is actually quite hard to track down any examples of.
As another European, I'd say a market without rules and arbiters will in no way converge to an utopia of fairness and freedom.

I'm sure Google is all too happy to fight with tiny European companies and eat their lunch. But only the EU can fine Google some $B and make them really think / change.

I think the EU is on the right track with GDPR.
Plenty of native apps are also not the best example of that, and not being able to control when they really die, including background running tasks, doesn't help.
Back in high school I did a map reduce job using split, sort, and a handwritten transformation and accumulation tool. It worked!
> You need specialized equipment to triangulate receivers, multiple vehicles

It's not "specialized", more like just dedicated, because those devices are pretty simple to create. Also, mathematically, one "running" vehicle is enough, but two is minimum for the sake of precision and efficiency.

> AFAIK Starling satellites use phased array antennas,

Phased arrays do leak signals all over the place ("side lobe"). If transmit power is high enough, this can be detected miles away. Say, during military exercise, activating phased-array based FCR randomly rings RWRs of nearby jets (if the signal is not whitelisted beforehand).

> maybe he will leave some kind of backdoor... Maybe it will be surprisingly easy to "crack" your Starlink receiver and set it to a fake country code, and suddenly have access to unfiltered US-region internet from anywhere

I don't get where people get this kind of blind optimism. The reality is that traffic control can be imposed based on physical location of satellite. Plus, VPN is cheap and works just okay, except occasional take downs. This new internet won't cause any kind of paradigm shift that some people desperately try to push.
