There’s a lot of context for these projects that an accountant would grok.

There are things like MWBE goals, where minorities must be contractors and have qualifying employees on these projects. Sometimes finding those employees is challenging. There are also labor peace agreements where the union demands a certain number of positions to keep their membership happy. (Laid off construction guys won’t vote for the union leadership)

There are a lot of stories about this stuff. Keep reading if you’d like to learn more.
Didi has been accepting payment via credit card for at least a few months now. It can be a pain to set up and doesn't always work but at least it's possible now.
There are things that could be done to make US healthcare a lot healthier economically.

They are all politically impossible to get through our political system.

One important thing to understand is that the billions and trillions that are wasted are income and livelihoods for millions of people, and they have huge political power.
Using a public agency to build stuff ? That’s socialism yo.
I can't talk about football with serious fans because they are obsessed with minutia, personalities, who did what, what games they have to win etc. In a way its revealing of who cares enough because you have to invest (waste) hours to keep up with that sort of stuff. What you're describing sounds like kind of a meta-football discussion about rules etc that I'd enjoy.
Why not let the US Digital Services be asked to step in for this project? They could either save the project or abandon what has been done and start afresh with a better and leaner approach. Or they could make an assessment whether the solution being envisioned is still relevant to the current situation.
Software vulnerabilities in Indian Railways' ticket booking code
I honestly used to browse the web without an adblocker and bounce from the site if it was too bad. About a year ago I ended up getting so fed up with not being able to visit pretty much any site that I installed one. I’m totally fine with being served ads, and recognize that it will even come with some not so friendly user tracking. Surely it must be possible to both serve me your content and ads at the same time. My only explanation is that it is pure laziness on all sides. The content maker gets paid if they display ads, the ad network gets paid if they fill ad slots, and the advertiser somehow sells more product (this I’m more skeptical of). So no one in that chain ever bothers to think of the end user.
They have an English UI now :)
> [...] My point is that to execute randomly downloaded code is realistically impossible to secure, practically used to deliver malware and usually used against the interests of the user of the computer. [...]

This argument has been rehashed over and over again. Some of the mass appeal of the web, as a platform, is that random arbitrary code can be downloaded and run inside a sandbox. It appears that these web technologies will continue to be used regardless of any security implications.

If users demand something like JavaScript or WebAssembly, do you have an alternative proposal to satisfy them?
I wonder how big a hole this is going to dig in Apple’s balance sheet. I have known many people who bought new iPhone because old one was getting too slow, not because they wanted even more thinner phone. This is especially true with families where cost of replacing iPhone is so prohibitive that no one wants to do it unless it’s absolutely needed. Now that this issue hasn’t got so much media attention I would think iPhone upgrades will hit major breaks.
I understand that the macbook pro is not perfect. Personally, I hate the touchbar.

The build quality, dev environment, multiple desktops are all critical to me being productive.

I've been using all three major OSs for years and I feel the most productive on the mac and I feel like the UX is the best.

I've been investigating other comparable laptops on the market in an attempt to "see what else is out there" because there are some things I don't like about the macbook pro direction (touchbar gimmick).

All of this is leading into my question: What laptop competes with the macbook pro in terms of build quality (i feel like I'm holding a hunk of metal and it's really satisfying), screen (1880p), trackpad, keyboard, and battery life?

Not to mention on top of all of that I get facetime and imessage which integrates with my phone. My laptop automatically unlocks because I have the apple watch.

I have an open mind and would love a linux laptop, but it really feels like nothing even comes close in comparison.
Yes, we're looking at the same page and I'm not being sarcastic. Despite the images, the total size of the page and its assets is <64KB and it loads extremely quickly.

For comparison, this page and its assets is >160KB and yet it contains a fraction of the content:

> I have no knowledge of New York subterranian transit, but at some point you have to step back and ask yourself if the expenditure is worth it, simply based on the value of the dollar. I think it is.

That may be true. But if NYC could get five times the amount of new track for the same money, I'd prefer that. Or spend the money revamping parts of the crumbling control systems. Or pay down debt.

The point is that NYC shouldn't spend more money than it has to.
I know how it feels. SVM's are an old and tried classification method that was in fashion before the DL craze.

> An SVM model is a representation of the examples as points in space, mapped so that the examples of the separate categories are divided by a clear gap that is as wide as possible. New examples are then mapped into that same space and predicted to belong to a category based on which side of the gap they fall.

One advantage of SVM's is that they don't use all data points to decide on the separation plane, just the closest points to the gap (the support vectors), making it more invariant.

Another advantage is that they can efficiently perform a non linear classification using the kernel trick, implicitly mapping their inputs into high dimensional feature spaces (here kernel means a distance function between two data points).

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

https://en.wikipedia.org/wiki/Positive-definite_kernel

I recommend Andrew Ng's ML course for learning about SVM's.
I just moved to NY from SF earlier this year, and I agree, it feels so much safer.
Ah yeah, I haven't had one with the touchbar yet, and I hope they figure out the folly of those before I need a new laptop.
Sure - NYC isn't crime free. But you're ignoring the actual data that shows the prevalence per capita to be substantially lower than SF.
Can't be worse than local politicians. The Corps would do the management and contract with local engineering concerns --at reasonable prices. Bring them from Texas, Illinois, who cares, so long as they can do the job.
> So, even if a miner mines a block with only 0-fee transactions, they are still rewarded with a small amount of Bitcoin "from nowhere".

Sure, but as long as there are transactions with fees in the mempool, then mining 0-fee transactions has an opportunity cost. Currently that's about 5 BTC per block, compared to the 12.5 BTC reward (https://www.smartbit.com.au/charts/transaction-fees-per-bloc...). It's possible that forgoing the transaction fees will make mining for you unprofitable if margins are thin.

Also, larger blocks are more likely to be orphaned, so including 0-transaction fees increases that risk (very slightly) with no additional reward (though currently the orphan rate appears to be basically zero, even with full blocks)

Carbon Ads are a good bet. Downside being the network is invite only.
It looks interesting but it definetly needs a "how to install/compile" doc. I cloned the github repo but I am kind of lost there.
Amazon started doing this. Absolutely hate it.
Yeah for real, I cant wait for the day a criminal gets busted because they used an AML/KYC enabled payment channel run by Goldman Sachs on bitcoin’s lightning network
But why include those transactions in the block at all? It’s perfectly valid to mine a block containing no transactions other than the block reward.
And what happens if the person in front of the person in front has reclined, he has worst of both worlds, and now it's late, cabin lights are off, and the person has been on another flight for 12hrs prior to connecting. When you also recline you slide you legs under the seat in front, perhaps this can mitigate the pain? Is it pain or just more uncomfortable? What height are you I'm 179cm I managed, and I recline, and I dont have a problem when the person in front reclines. My friend is 190cm and he has no problem, although of course he'd rather people didn't recline. Any time someone has complained about the person in front reclining the cabin crew have always explained it is in there right to do so?

I think you might just not be suited to traveling in economy if you need to demand the person doesn't recline, you've made his/her journey significantly worse by choosing a chair incompatible with your frame - yes its suck if your tall.
This question is a bit out my domain, but I believe the answer boils down to being able to re-use one antenna for send and receive with push-to-talk, but for full-duplex communication you either need another antenna, or more complex signal processing.
Out of curiosity, how did you end up with this beast at the time? According to that German site, only a few thousand were made and sold.
Why would anyone believe the bitcoins will end up going to charity?
It's not very interesting, and starts with a rant about HN.
The real question to me is what else do consumers don't know about the products they are buying from Apple, Amazon and other big companies. Look at the great length we have to go to make sure there was no foul play.

Monero and associated technologies have no scaling solution on the table. It is a problem.

Monero’s tx fees are low due to lack of use, they go up way faster than bitcoin’s even with RuffCT and adaptive blocksizes.
It will be interesting to see how other companies which base their products on Lithium ion batteries deal with similar degradation. For example, How will Tesla handle this scenario? Will they slow down the car when the battery performance is not adequate? Interesting to see how companies make tradeoffs.
I wonder how possible it would be to visually extract crypto keys baked into the processor for newer models

AFAIK the Intel ones use public-key encryption[1], so you would not really gain anything. They obviously thought of this.

[1] http://inertiawar.com/microcode/ - 2048-bit RSA too, so not really breakable in the near future either.
Closer to this, but with different numbers.
Imagine the limit of a $0 exemption for the US estate tax. What an unbelievably unpopular and inconvenient thing. The middle class selling dead parents houses to cover inheritance. Many small businesses dismantled. Liquidating stock portfolios in poor market conditions. Those of any means whatsoever would jump through hoops to avoid the harm and hassle. The burden and overhead of the gifting and paperwork would consume excessive amounts of time in what is not useful economic activity.

I second that. My 2 year old Moto G was near unusable at the end. When it reached 15% charge it would just die.
How was Apple late to the game with edge to edge displays? They only started appearing on flagships in 2017, this is their first phone release since then. Not to mention most of the "edge-to-edge" android phones are not edge to edge. The S8/Note 8, Pixel 2/2XL, LG V30, and OnePlus 5t all have significantly larger chins and foreheads than the iPhone X. The only thing I think that comes close(and I'd say beats it) is the essential phone.
Sure thought experiment:

They have more power. Let’s say they get what they want. Double the working conditions and double the wage.

Now what?

Everyone needs to eat, needs to sleep. Ok let’s raise the prices. They can afford it. I.e they can no longer afford it.

Meanwhile, since food costs more so farmland costs more. Increasing barriers to entry.

So they strike and ... the cycle continues.

Basically, goods with the highest price elasticity of demand win. And they win by leaps and bounds.
There are plenty of altcoins with short block times. One downside is that they increase the frequency of orphaned blocks and chain reorganizations.

Anyway, doesn’t it amount to the same thing? 2 MB every 10 minutes or 1 MB every 5 minutes, your node still has to do roughly the same amount of work to validate blocks.
It only seems like a waste because it's not your thing. I don't care for it, but I also don't care for 90% of what's in the tech press. Most of it is meaningless (who will remember that random funding round/the player who won't last a season five years from now?), but it's fine entertainment if that's what you want.
Difficulty of mining is adjusted every 2016 blocks to maintain a rate of one block per 10 minutes, so since the rate of block generation is set, and the reward shrinking rate is also set, you can predict when all bitcoin have been mined.
The problem NYC is facing isn't the tech. The MTA's tunnel-boring machines can be operated with far fewer people.
“On Earth” isn’t very descriptive of what the article is about. The new one is.
> [...] serve ads from the content web server and make it indistinguishable from content

This sounds like an argument for sponsored content. At least with the current ad strategy, it can be relatively easy for a user distinguish ads from content. How do we distinguish a YouTube video that ends with the statement "this video was brought to you by [sponsor not relevant to the content]" and a YouTube version of an infomercial?
Meanwhile, progressive-leaning organizations have been pushing for the elimination of SALT deductions for years, on the logic that it primarily benefits the wealthy residents in high tax states.

The Center for American Progress was urging the Obama administration to eliminate those tax deductions[1]. Politifact fact-checked a Pelosi claim, and came to the same conclusion, that the SALT deudction "is a tax deduction that disproportionately benefits higher-income taxpayers[2]". Only 10% of filers earning under $50k a year even bother claiming the deduction[3][4].

Why is HN negative against crypto?
One would expect this community to back this technology and financial/social revolution it brings.

Is it that there are ties to traditional system like SV billionaire VCs? But those same guys that are popular in HN do like crypto.

Horowitz is very much into it, YC is onboarding blockchain startups, hell even Techcrunch founder says he only invests in ICOs right now.

Is it missed out negativity?

Your thoughts?
I love to exercise. I could do it all day long. I have often walked 3-4 hours a day when the air quality is good ...

and thats the problem. Many people, myself included, live in areas where the AQI leaves me wondering if I'm actually harming myself by being outside and exercising.

Right now the Airnow AQI for Denver, PM 2.5 is yellow (Unusually sensitive people should consider reducing prolonged or heavy exertion). I think that includes people that exercise, so I won't walk. But these mathematical models leave me wondering about their accuracy, how many sensors were used, are they accurate at this exact moment, etc.

I wish there was better information at our disposal where we could make better decisions on when a dosage of exercise is worth it given a certain AQI (PM2.5, PM2.10, Ozone, etc).

Neither (a) or (b) is true, flying between Europe and Asia we pretty much get all the new planes from FinnAir A350s, to completely refurbed 777 (with brand new slimline seats as part of the 10 across densitification rollouts), to dreamliner 787s on Qatar, Oman and Norweigan (some are a few years old but many recently delivered), plus new smelling A321neos regionally. Occasionally we see an old A380 after a refurb too. All seats have the recline button. Never heard the hurt your neighbor argument - but I can't imagine them allowing you to fly if it going be mandated seat in front is upright to prevent medical injury - that would be a flight risk in the event of evacuation. You should take these arguments to FAA and airline though if you're serious rather than some unwritten code of conduct you expect the guy in front to follow when the person in front of him probably won't.

I had one incident though where the guy sat next to me was huge and naturally overflowing into my seat, I was moved to an exit seat prior to take over, I still submitted a complaint as he should been assign two seats (weather that's free if medical or covered by the airline or his pocket I don't care - not my problem). I worry that scenario happening again, but I won't be worrying about recline, speak to the airline about your specific requirements as they not going to embraced by the travelling public - upright for several hours - no thanks.

Note to very tall people: KLM and FinnAir have economy comfort, this isn't premium economy, same poor seat width, but 3" more legroom. Emirates are also looking at dividing their economy class in multiple classes presumably some with more legroom. Extra legroom seats can be booked on SingaporeAir, Malaysia, Emirates, and Oman air^. You don't need Y+ if you just want more legroom. These seats are generally only $50-$100 more per segment. ^ Not exhaustive
Reading code is the equivalent of looking at solutions for math problems... is it more helpful reading the solutions without context or with? You need to see the original problem, and how the solution came about in response to that problem. In regard to this, I would say, pick a problem that has a solution (walkthrough, if possible) available and then attempt to solve it and then honestly check your solution against the given solution.
Movie ushers? What century was the last time you visited the theatre? I go to a lot of movies, and outside of a couple of special events, I've never seen an usher in the theater.
Yes, cell phones and it's might be an issue, but they are fairly rare.
Unless you can built a $100k theatre room, there is definitely a clear winner. But if course it isn't for everyone.
The reason why Apple requires you to press the physical side button to confirm
a purchase with Apple Pay or in the App Store is because pressing the side
button can’t be faked by an app. If it was an on-screen button, a nefarious app
could present a fake Apple Pay button. With any normal app, clicking the side
button once will always lock the screen, and double-clicking will put you in
Apple Pay mode. Only Apple’s own software can override the side button like this.
Double clicking the side button to confirm a purchase effectively guarantees that
it was a legitimate payment experience.

To what end? You don't enter a password or anything when using Apple Pay, so the only thing this "nefarious" app could do is trick you into thinking that you paid for something you didn't. And wouldn't this sort of thing get caught in app review and/or get the app yanked from the store when discovered? I honestly can't figure out what the downside would be to having a "pay with Apple Pay" button on the screen.

As an aside, I don't like having to press the side button for Apple Pay on my iPhone X. I usually have to shift how I'm holding it to get the proper leverage to double-press the button. Double pressing the home button was way easier.

To my mind, this is a reasonable collection of related writings on the topic by me:

http://micheleincalifornia.blogspot.com/p/ir2.html

But I don't know that it will seem pertinent to you. So let me try to give you a nutshell version:

Average size of new homes in the US has more than doubled since the 1950s. Meanwhile, average number of occupants has dropped.

We tore down up to 80 percent of SROs, a low cost form of housing that used to be common, but now has to be explained because people don't know what they are, so here is a link in case you don't know: https://en.m.wikipedia.org/wiki/Single_room_occupancy

Healthcare in the US accounts for a crazy high percentage of expenses and this disproportionately impacts the poor.

If 20 percent or more of your income is eaten by healthcare and 50 percent or more is eaten by housing costs, life will be pretty damn bleak and UBI won't solve it. This likely is a large factor in things like the opioid crisis and rising suicide rates.

Poverty in the US should not routinely mean homelessness or being unable to afford essential healthcare. It should mean you live in a tiny speck of an apartment and you can't afford a fancy wardrobe.

The way we abandon our own people in a very rich country is monstrous and certainly promotes depression for a lot of people. I spent years homeless and asking for help to figure out how to make money online from people who make money online. The way I was treated was pretty psychologically scarring.

I'm a tough cookie and have more support than is apparent from my general lack of sufficient income. If I had less education or less social support or whatever, I would not have overcome all that. I would have been destroyed by it.

So I infer that's an issue for many Americans.

You aren't required to agree. That's just what I think.
The U.S. legislative system has to cater to everyone's interests. Which is not bad per se, but when it comes to something like this, new environmental laws will always hollow out an entire industry. No matter what new enforcement they try to enact, there'll always be someone powerful lobbying against it.
