Ask HN: Would you pay a service that enables you to send updates to visitors
I'm working on this product by which I hope to convert the visitors who are not willing to commit their email to your service just yet. Our service collects their emails on your behalf to send them updates (which you will send) about their interest/product.

For example, let us say you run a phone blog and you have a lot of visitors and very few give out their email addresses. This way you cannot reach the visitors again for a followup update about the things they were interested in. Our service collects the emails of the visitors for sending updates about the particular phone they were interested in. You can then send updates to that list about that particular phone and turn them into returning visitors and maybe make them purchase that phone through a referral link after it is launched.

Do you find value in a service like this, that helps you send super relevant updates to your visitors who aren't yet committed enough to give you their email address? Would you pay for such a service?
I think your first part is right - and would fit the general trend of people earning less and having longer hours or less convenient schedules - but the second part seems way off. Running, jogging, hiking, and cycling seem at least as popular as ever, which would also fit the theory that sports which have a larger logistical and equipment footprint are more affected by the general decline in economic security. Something like diving or mountaineering costs a lot more in time just to acquire the skills you need to go on a trip but almost anyone can slip on some athletic shoes or ride a bike casually.
Used car + gas + insurance + repairs is certainly not cheaper than an high-end Macbook + electricity to run it.
I like the integration of the Continuous Integration, Continuous Deployment, Continuous Delivery compares to GitHub.

> GMOs are no more risky than traditional breeding and mutagenics

It can be argued the risks are adequately protected against, but to say they are equal just seems like intransegence. As technologies advance the potential utility and risks raise together. Would you not be more concerned by an adversary weaponising modern GE than traditional breeding?
Owning a car is one thing. It depends on where you live, where you work, and your preferences.

However, I literally would not have been able to have done any job I've ever had without the ability to drive. (I'm not talking about commuting although that's been the case, but driving to customer sites, driving to remote transportation with one job, etc.)

To say nothing about countless travel experiences which wouldn't have been possible without driving. Even my friends in cities like SF who don't own cars and use Uber extensively, still rent cars and use Zipcar on a regular basis.
> Samsung's design breaks correctly written user-land code.

Are you sure? From the article, it sounds to me that the real cause of the error is an incorrect assumption made by the GCC people.
KDB+ does have some disadvantages though.

Requiring a schema makes it ill-suited to many use cases since in many situations you don't know the schema ahead of time. And the biggest for me is poor Hadoop/Spark integration. JDBC is not a great choice since you have poor predicate pushdown support and it prevents say Spark from going specifically to the node with the data.

I don't know if this is true. I think I agree with you, but have no idea if the data supports it. Sports and outdoor leisure activities sometimes seem more accessible than ever.

A lot of comments about how expensive cars are. Do Americans really have to borrow money to buy cars? Where I come from, the used car market is huge. They're about the price of a laptop or a couple of smartphones. Even young people can afford them.
While the article says more technology in cars might entice millenial buyers, I feel like tech in cars is actually a disincentive for anyone interested in technology. With a few notable exceptions, most car tech seems like embarrassing garbage that's hardly enticing when it's brand new, much less at the end of a typical car's lifetime. Car development doesn't keep pace with things like smartphones, people keep cars much longer, and automakers don't seem inclined to offer much in the way of updates once they have your money.
How can they write that as a plus when it is the same screen size and resolution as the previous model

If I make a display with twice the pixels, ten times the size, and give it 16-bit dithering color, will you call it obviously better based on more pixels + larger?

Or are there factors other than dimensions and pixel count that affect how we evaluate display technology?
The danish tax system is "simpler" than that of the United States, but it is very far from "simple and all inclusive".
Wow, that's very neat! Thank you! Does Clang support this as well?

It looks like I don't need the main.o(.text) line either, which is good because that would be a large burden on users of the library.

Also, just noting for others, I had to use .text : { libco.o(.rdata); } since my char array was const.

That turns the address from a compile-time constant into a pointer. This function is used tens of millions of times a second, so that cost would add up. I covered this in my initial post, though :/
"Human in loop" swapping floppies. Byzantine.
Pretty sure those two things (scratch/scuff on the jet black and thickness) are completely unrelated. It's scratches because of how they've created the finish. It could weigh 10kg and be 20cm X 20cm X 20cm and it would still scratch.
I'm not in Denmark but in a very similar European country. I don't want the high taxes. The current taxes and mandatory payments feel unfair.

The generations before us worked during the greatest economic boom in history, were mostly employed in safe and high paying government jobs (still are), bought houses before their values tripled, and are now receiving monthly pension payments that are almost twice what most young people earn through work. My effective tax rate is more than 50% (including mandatory pension payments that are more than 10% of my pre-tax pay). A good part of that goes to pay the pensions of existing retirees. A third of my remaining pay goes into paying rent for the apartments owned by the older generation. In the end, I get around 1.5k euro out of the 7k I cost my company (employers also have to pay additional social and pension payments).

Looking at the current luxurious lifestyle of the older generations, and the rapidly ageing population, and increasing youth unemployment — I want out.
What does that have to do with having an easily scratchable finish???
> A formal system cannot in general prove that it is reliable, i.e. that if it proves statement P then P is true

This implies second order logic. It is not clear to me, whether the loss of consistency is warranted. Type Theories are tried to avoid inconsistence. However high the order of the processing logic is, its only reason to exist is to output first order theorems, those we can prove decidable.

> But with this article, the hope is that a formal system can show that the statement about itself is probably true.

Probabilty is not good enough. The Bayesian Conspiracy sure is strong, but I'd prefer to stay with first order logic and finite state machines that are provably correct.

> > The short answer is that this theorem illustrates the basic kind of self-reference involved when an algorithm considers its own output as part of the
universe

Isn't that what differential equations are for? I'm tired of the liars paradoxon. Intuitively, I've settled on the presumption that paradoxa always rest on wrong assumptions.

I'm no mathematician, but I refuse the notion that I am inherently unable to be certain. That's why algorithms are by my preferred definition bound to be deterministic. I'd like to be able to tie this in with the Chomsky Hierarchy, albeit I am not that advanced. I'm no mathematician and I'm impressed by quines. I guess, the halting problem implies that quines cannot always be predicted. Heuristics help there and that's what stochastic is all about.

Let me be clear. The paradoxon "this sentence is a lie" is neither a sentence, nor a lie. That's a question of definition. Of course I'm in no position to say a similar thing about Goedels incompleteness theorem, and I even referred to it's result in higher order logics, but I still doubt the relevance, as many seem to be ignorant of his former completeness theorem.

The higher order logic and self reference is related to recursively enumerable grammars low in the Chomsky Hierarchy. Though, if ordered by magnitude, I'd call it higher. I hope, if the goal is natural language, we don't need to aim that high. If you want a computer that computes computers, though, go for it.

> A formal system cannot achieve this by simulating itself.

The type of self similarity used in quines or the liars paradox seems to play an important role in what we perceive as intelligent. Although, I stipulate, the intelligence involved is the ability to tell the difference between a misleading liars paradox and constructively provable quines. Of course, a machine that doesn't need verification from the supervising developer would be akin to a perpetuum mobile.

It is easy to supervise the AGI's output by the less intelligent machines that have to do the output. The focus is on optimizing the processes, not the inability to assert safety guidelines.

Edit: mixed up the order of the Chomsky Hierarchy.
Thanks! Couldn't have done it without our great community and team. How can we help to improve the design of GitLab?
Also, if we're including cost of a data plan for the phone, I think it's only fair to include gas and maintenance in the cost of the car.
Well sure, but that doesn't make him an idiot.
> In other countries, taxes are complicated (no citation needed).

Lots of citations needed actually, from what I know of it the Belgian tax system sounds pretty similar to the Danish one for employees (most taxes are held directly on salary, there's a year-end tally for deductions and the like if necessary), tax rate is ~40% of income.
InfluxDB is perfect for these use cases. It's a single Go binary with excellent performance and use of resources.

I find it fascinating that a review of an extremely complex piece of technology devotes 1,500 words to the color of the back of the thing. What a world.
It's interesting to me how much effort is being spent on adding tools like issue tracking, build pipelines, deploy management, etc. vs just providing good hooks for standalone tools that do all those things.

We have discussions about Jenkins vs Concourse, where to keep ansible vault passwords, should documentation live in Github wiki or in Confluence (apparently "tech" documentation in the form, "business" documentation in the latter - what if it's both? Who decides?), and so on.

There is something nice about being able to go to a single place and saying "OK, it's all here in this box". Github has made inroads with some of this stuff, but not quite enough. Gitlab could try and do all this, but then people will moan ("I prefer JIRA/Trello/whatever").

Most of the pain around developer/business workflow around us at the moment actually comes down to the fact that nobody has _really_ thought about providing a great unified UX for all of this.

Part of the concern is people want to be "flexible". No, dictate, just make sure what you dictate is a better solution to what people have.

If GitLab get it right, github could be a minor player (unless they keep up) in a few years time.
I have always felt NetBeans lagged behind Eclipse (and Idea) under Sun and even more so under Oracle. I think transferring to Apache would be a good thing overall for the NetBeans project.
SpaceX: Giant Leaps, Deep Troughs, but No Plateaus
Thank you! We're always trying to build great new tools that are helpful.
I'm in Norway. In the city I'm at, a car is definitely a luxury. We have a used one that is only used to transport heavy goods (kitty litter) and go out of town occasionally. I still walk to the grocery store and most places in town or ride the bus.

However, we would go out of town before we had a car... because public transportation is really a thing. City to city. Not all-inclusive, but enough that one can travel to the outdoors so long as you are willing to walk or cycle as well. It just takes slightly more planning is all.

I could have never had this sort of car-less freedom in the states. Living in a larger city was probably one thing, but getting from city to city - or city to the outdoors - was quite another entirely.
Only the absolute worst ones, and you're ignoring the cost of repairs (significant on a junker), fuel and other consumables, insurance, in many cases parking and tolls, and in some cities you pay property tax or other non-trivial annual levies.

In a large city just parking alone can be a MacBook every couple of months unless your employer subsidizes it.
Depending on what switch you're plugging into, this could easily be Cisco Portfast or similar catching you out.

When the port goes active (layer 2 link) the switch inspects but doesn't forward packets to try and ensure you've not just added a loop into your ethernet network. After a minute or so, if everything looks normal, the switch then starts letting the device talk to the rest of the network.

If you don't know about it then this can be annoying at best as you seem to have a layer2 link but DHCP can seem to take an age to start working :)
Yeah, I take a lot of flack from this from other people. But I'm sorry; I'm not going to write the code in GNU as (and that godawful AT&T syntax) or nasm/yasm (and require another tool to build the library), require a second compiled object for the library, and lose compatibility with Visual C++ and Clang.

Also, apologies to HN. I wasn't trying to turn this into a "help me with my problem" discussion. I was just pointing out how adding extra security can have unintended consequences to other applications with an actual example.
I stopped reading this on mobile because backchannel.com has the most initiative intrusive dropdown-popup nag every 10-20 seconds demanding you log in.
I bought a Ubiquity a few months ago, and found out that it couldn't communicate over wireless with a Raspberry Pi's USB-WiFi dongle (with drivers in mainline kernel) sitting 3 meters away. Before I bought it, the same dongle was acting just fine as access point for the whole home network of 3-4 phones/tablets and 1-2 computers; it could easily handle browsing, updating Android/iOS apps, and YouTube video streaming. And it still is doing that just fine after I sadly had to return the Ubiquity!

Now of course this is just my own anecdote. But it remains a fact that WiFi setup can be incredibly hit-or-miss, and there's no reason in principle why two devices 3 meters away should have occasional 2-3 seconds packet delays.

Just a few years ago I was in love with Github and felt nothing could ever displace it. But as time went on, they just fell asleep at the wheel. I've been using Gitlab for the last six months and there is no chance I would ever go back to being a paying customer of Github. I'm so glad to hear GitLab raised more money to keep going!
This would probaly not work on some shitty audio cards with shitty drivers that have explicitly removed "stereo mix" for "copyright purposes".
Ask HN: Do banks use OLTP or event sourcing to process money transactions?
We were having a "lunch" discussion if banks still take every transaction and write it to an OLTP database, or do they use event sourcing. The fact that ATMs need to provide money when disconnected, or the fact that transaction takes 24h to approve suggest it might not be a direct OLTP transaction. Anyone implemented a bank system care to shed some light on the matter ?
Let's be serious here. I'm French, all for high taxes and all but please let's not delude ourselves thinking that American people pay "around 50%" taxes. As soon as you have enough money to afford it, you'll pay a tax lawyer to get that down to about 15% or something, thanks to a bajillion hidden tax system loopholes allowing the rich to get an advantage on the less fortunate.

And even if you take into account the price of college, health care and everything, you'll get to about the same amount but the whole point in the US system is that you do NOT have to pay for other people, cause who needs solidarity in a society.
Exactly this has crossed my mind many times. What's the point of having a super thin phone with really nice design if you're going to keep it in a thick pink rubber literally all the time?
100% free sets up perverse incentives. The minimum subsidy is 70% and there are effective price controls. So the actual bill is often higher in the US for those with decent insurance.
Running a used car for a year costs much more than buying another Macbook.
I think for many, cause and effect are reversed from your theory. Hobbies that more or less require a car are less popular with people that do not need a car otherwise, or are moved to locations & styles that are accessible without one.

Not having a car limits my outdoor locations to what I can reach by bike and public transport (and my holiday travel locations), but it's hard to justify the hassle of a car just for that. Still enough interesting locations around.
The whole car pride is a thing of the past. It used to define who you were and prove your success. People are simply evolving and take the car for what it is, it's simply transportation and you shouldn't make a big deal out of it, nor you should go in massive debt for it. If the car industry wants to change, making better quality, cheaper car, less polluting and smaller or more intelligent, it might benefit them a lot.

Maybe for people who only use cars for the monthly Ikea trip but there are a world of use cases where ownership makes sense, basically any time you want to use a vehicle as "mobile storage of stuff".
Show HN: The Barometer Is Back, and It's Built on Big Data
IC IVAU instructions are broadcast to all cores in the same 'inner shareable domain' (all cores running the same OS instance are in the same inner shareable domain)
> Why not mention the lack of SD card slot or removable battery?

Because only a tiny but vocal minority cares about it.

iCloud is taking care of photos, there are large GB models and most people needing more battery life are just buying those $10 lipstick USB chargers.
because nobody needs an sd card slot. and nobody replaces their battery. at least not in an iphone. i've owned 4 iphones since 2009 and _never_ had to replace a battery. the phones are still working, btw. (well, the 4s battery would need a replacement - after 4! years)

these two are just bs benchmarks. like floppy disks and dvd drives.

edit: the display. well, i'd go so far as to say that nobody in the industry has as good as displays as apple. and nobody needs higher resolutions on that physical space when they already can't see pixels anymore.
>that'll be at least another 50$

Maybe for the bare minimum liability. But if there's a lien on the car (because it's leased or financed) then you're required to have comprehensive insurance. Combined with the fact that a new driver will have higher rates and I think you'd be hard pressed to find a rate below $150 a month.

>oh wait! theres also the various fees

And maintenance. 4 oil changes a year, tires, brakes, belts and other things that need to be replaced regularly probably adds another $1000 per year.

Cars are definitely an excessive expense. I know because I've owned (at least) one my whole life. Then again, my car affords me the ability to live in an area where the cost of living is far below New York, San Francisco, Vancouver or Toronto.
I think they were referring to unintended risks. There's probably less chance modify a plant in an inadvertently bad way with GE as its more precise. But yes if you want to weaponise an organism, it easier with GE.

However, from my understanding, the regulations of GMOs are much more stringent than for other types of breeding.

You can traditionally breed a potato to have high levels of solanine and i'm not sure whether regulations would stop it from going to market.
I think by hiring a team. It's time to get serious now. Because Github gets it: https://dribbble.com/github
That is a very simplistic attitude. First of all, I have met countless entrepreneurs who support this "scheme", just to counter your anecdotal evidence. Second, shouldn't a "welfare scheme" benefit the poor, not exist at the expense of them? Are you arguing that the danish welfare system failed in what could be considered it's most essential undertaking? Third, "benefits the majority at the expense of the productive few" doesn't ring true to me. You make it sound like the "productive few" do not receive the same benefits as everyone else, and that the fact that everyone else receives benefits is inconsequential. It's not. Time and again (financial) equality in society has proven to be immeasurably beneficial, in so many regards.
Hey Paul - All great notes. We believe in a single solution from idea to production. More about that here: https://about.gitlab.com/direction/#scope

We hope to make it easy to go to a single place for everything needed for development from issue boards, CI, analytics, etc. The unified UX for this tool is key and we are hiring a great team to support that goal.

Later today we're having a live event to talk more about that vision and answer questions. https://page.gitlab.com/20160913_unveilingmasterplan_landing...

Again, love the notes and how you're thinking about this. Happy we are aligned!

I'm pretty sure you can argue for personal car ownership in a self-driving world. Do you want to get into a shared vehicle right after the guy who puked up his dinner? Have you ever been in a public restroom? Some people will not want to use shared transportation. Other people may see ownership and customization of a self-driving car as the ultimate status symbol.
