Ask HN: Thoughts on the universal Linux packages called “snaps”?
I noted that Ubuntu/Canonical is pushing Snaps recently but don't hear much discussion about it, I see it as an "Electron for Linux distributions" (not necessarily in a bad way), sounds good for the Linux ecosystem!

How about performance?, anyone have experience working with this as a developer? (I'm a designer), share your thoughts!

I recently installed the Spotify Snap [1] on Ubuntu and was really easy and works flawlessly.

Does robinhood run their own prop group or just sell their order flow to Goldman, etc? What a scummy organization...
Just to play devils advocate on this, this isn't very free market. How is this not clearly choosing winners and losers? What about the plastic bag producing companies and their shareholders? The government is choosing multi-use bag makers over single use bag makers.

I feel like this is "common sense" enough that people don't fight it, but if it is a more complex (and more important) issue like climate change and banning polluting power sources, it all the sudden becomes an ideological and philosophical issue and we have to just wait until the economics are just right to see whether we'll survive or not.

Why can't we treat polluting our air and water in the same way? Just because we don't have to see the pollution blowing around the roadway we aren't going to worry about it?

The problem is that businesses initially built around genuinely amateur money-making on the side (Airbnb, eBay, Etsy, I'm sure many others) tend to attract professionals who often push many of the initial users out. And the higher volumes are more attractive for the businesses mediating the service so they don't have much incentive to really stop it.

It does open up the opportunity for new entrants to come in that are like "X but in the old days." Though it's now harder with a big incumbent and the cycle will probably repeat again if they're successful.
I think the point of the whole article is that GM was able to make sure people only use the system when it was capable of working, where as Tesla's system can be used when it shouldn't be. He gets very distracted through out and accidentally mentions how good Tesla's self driving is.

As an aside, I rather Tesla's strategy to GM's. In 10 years when the tech is there, will this Cadillac simply handle freeways better? Seems like the car is locked in to a specific subset of self driving for the life of the car.
I don't disagree with anything you wrote nor do I see how it contradicts anything I wrote. Just because it works doesn't make it right and running to the government and using the long arm of the law IMO should be reserved for egregious crimes lest it become regressive and commonplace.

This whole recent update to Snapchat has been horrible in almost every way. Haven't heard a single good thing from the people I know who use it. My question is how does an update that is almost universally hated by the user base get through to production? Does Snapchat not have any user feedback in their design or is it simply "How can we make more money"?

Seems to me Snapchat forgot the most important thing about a products profitability: the customers.
Out of 1,332 words, 92 (7%) were spent on issues particular to women, and some of those 92 words were spent praising the egalitarian nature of her marriage/how much her husband helps. I think you're projecting a lot.
Grant Cardone is one.
Rural American mail trucks are being replaced with barely-running junk minivans or really whatever can be purchased for the cheapest possible amount, probably the lease emission-aware solution I can think of. I’m not sure if these are workers providing their own transportation on contract or what, but I have seen some very sketchy vehicles delivering mail in multiple states around the US lately.
That’s bad, but it’s not to exploit influence over you for profit.
I've seen what you describe as "hissy fits" (and well-reasoned, substantive comments for that matter) come from all points of the political and ideological spectrum. The most deeply embedded sociopolitical view I'm aware of is the natural human bias that "it's the $otherSide that's responsible for misbehavior".
Thanks for taking the time to bring up these counterpoints!

>why should it have some cost different than the cost of 'promoting' something when you upvote

If this is a blocker, show both! My recommendation to add the tiniest bit of friction only to the anonymous negative was an attempt to reflect existing site guidelines. My apologies if terminology is a distraction; I did add "censuring" as a better word.

>mods' argument that meta is bad for actual conversation

Up/down votes are currently only public on the receiver's side, and this meta gamification powers HN. Would revealing the other side of the equation deter abuse of anonymous control (with an acceptable level of side effects)? All I can answer for sure is that intervention for downvote abuse (if any) is behind-the-scenes for now.

[I assume] the pool of eligible downvoters continues to grow; maybe when the time comes the next step will be another moderator rather than crowdsourcing -- the precedent of hiding individual comment scores seems relevant.
This is literally the standard market solution for externalities, and follows the same basic logic as carbon taxes, cap-and-trade for SO2/NOx emissions, and so forth.
Thanks! Looking forward to hearing early feedback. I'm still in line.
I just quit a job where I dealt with both self-managed and micromanaged roles, and I was much more productive (and better rewarded) in the self-managed one. I found I'm better at managing lateral relationships, eg data-scientist to data infra, or data infra to devOps, than being micromanaged on a ticket queue. I was surprised that I enjoyed fairly mundane backup or recovery tasks, because I could see user impact directly.

The micromanaged situation had strange priorities as well; the overhead of trying to figure out why we were doing so much stupid stuff just added to the frustration.
My understanding is that as a professional couple, that is "service businesses", my wife and I are hit super-damn-hard by the new tax law.

Apparently working for your income, rather than rent-seeking or capital investment, is something to be discouraged in the modern economy.

I feel guilty when I get a soothie somewhere and don't have my straws and decide to go ahead and get a plastic one because I really want to drink it on the way home. Definitely good to have though. You need a nice pipette thing to clean them but it really isn't that hard.

Would a self-driving car need perfect dead reckoning? I was able to update my assumptions about my distance and location based on street signs before I had GPS...
I agree with this completely! Bitcoin evangelist Trace Mayer always harps on keeping your private keys and not using exchanges to hold large amounts of coins. And Mayer's an investor in Kraken, one of the big exchanges. I have taught my friends this and they all had interest in it, but some skeptical if they trusted in themself enough to hold onto their coins offline.
I usually check AirBnB but lately the best prices after fees are higher than mainstream hotel brands. To a certain extent this is controlled by property owners more than AirBnB itself, they've figured out they can charge more.

The result is that while I used to go to AirBnB for the discounts, it's now becoming a premium brand with a premium price.

It may be worth noting that I always opt for "whole place." It may be different if you're willing to get just a room.
Curious though, would you buy this car over a Tesla (basing your decision on the self driving features only)? The reason I ask is because if I buy a Tesla, I have the idea that one day it will be completely self driving one day. With this Cadillac, I would expect it to only do this specific subset of self driving for the life of the car.
Regardless of what you, I or others in 'our' sphere might think, there's a lot of traction in playing the conservative card when it comes to cars hurtling down roads.

Every day that goes by without a shift to autonomous driving, we lose 70 or so people in the US alone. Why this isn't being treated as a Manhattan- or Apollo-scale project, I don't understand.

A conservative approach is not what's called for here. We can afford to break a few eggs on the way. Sounds heartless... but sorry, that's what the math says.

If anything, the undergrads should be your only dating pool. Older women come with too many entitlements and strings attached and you're essentially on the clock to start a family with them.
Apart from the "texting and trading"-part I don't get why it's appalling at all! Other than that it's a playful and stylish ad about the "to the moon" crypto inside joke.
> npm is not for managing system software

Debatable but irrelevant.

I'm not saying npm is a good or bad system package manager, just that running arbitrary scripts for requested packages and their dependencies is hardly unique.

It's oblivious to single out npm as a package manager that allows you to be pwned by packages in whatever repo you pull from.
I feel like they could drop the price by making them read-only. I just want to read full-size pdfs.

Not all continuous optimization algorithms can handle arbitrary equality constraints, especially if they effectively make the optimization domain discrete. You might be able to do an encoding of NP-complete problems that is purely continuous, but if I read the LIPO paper correctly, there is a known exponential lower bound for their problem, so that would just make the NP-complete problem harder.

Instead, the algorithm promises to actually match that lower bound, while always being at least as good as random search, and offering exponentially large improvements in certain cases. Not exactly the kind of claim that has implications for P =? NP.
Pyenv is great. On our Macs we've had zero issues installing older, specific versions of Python, every time. Highly recommended. (Getting it working properly with zsh was a bit frustrating, but that's my own fault.)
Not really. Hell banning is a silent action. You don't tell the user they were banned.

You got several warnings, and then you were told you were banned.

EDIT: just for clarity: I'm not a mod.
Answer: it doesn't.

Genetic algorithms and the like are pretty much all terrible. They're ways of approximating your gradient, and fall to the curse of dimensionality. The only reason Uber and open.ai published their papers on evolutionary strategies (something pretty different from what people think of as genetic algorithms) is that current policy gradient methods are really bad as well, allowing what is effectively random search to do well.

It's kinda like how Bayesian hyperparameter optimization is pretty terrible and 2x random search almost always beats it easily.
Even Honda has autonomous driving. The Honda Sensing on Honda's 2018 is great - just like what they showed in the video here.
Do you have a citation for that? It sounds plausible but I bet the real situation is more complicated.

The highway speed limit may be 70mph, say, but from an emissions point of view, for most cars the ideal speed is more like 60mph.

From a safety point of view, the ideal speed will depend largely on traffic conditions. 85mph might be fine in light traffic on a straight road in clear weather in daylight, less so in other conditions. That seems like a good argument for lowballing the speed limit (assuming that you're correct about that).

I hate seeing these extremist bans. I was homeless in California when the bag ban went into effect. Following hot on the heels of the bag ban a hepatitis epidemic broke out in Southern California. I believe these two things are related.

I have a permanently compromised immune system. Reusing bags is problematic for me. However, I use grocery bags as trash bags. I almost never buy trash bags. This has basically been true my entire adult life. I bet a lot of people reusing grocery bags are buying trash bags separately.

I am very concerned that when we outright ban disposable bags and utensils we create a health risk that may go unrecognized.

Using metal straws and trying to clean them between uses strikes me as very problematic. That strikes me as a tremendous opportunity to foster antibiotic resistant infections.

I really wish the world would stop and wonder why such products are so popular instead of decrying them as clearly lazy and evil and no-good-nik. Because I fear that a lot of people will mysteriously die of illness and wondering if there is a connection to the ban of disposable items will mark you as a loony.
the whole field of modern "ai" is about 6 years old (since AlexNet won ImageNet), so 18 months is quite a long time.

More importantly, a review of flash performance is something that can be reasonable to perform, as another more long term reliability oriented one also can be.

The lesson for Snapchat, and really any new software company, is that design updates need to roll out slowly. You cannot drop a boat load of changes on users. Facebook learned this early on when they introduced the new wall and news feed. Now they allow you to preview design changes before they get fully rolled out.

The design changes aren't necessarily bad, it still looks and operates fine. Snapchat just made the rookie mistake of changing everything at once before anyone could orient themselves around the changes.
But it's turtles all the way down. How does the public know that they're getting the data and not a surrepetitiously modified version? At some point you're relying on the system to be truthful about its contents.
Duration of 1h??

That's... astonishing.
> Their decision to limit the initial problem domain is genius

I believe it's called "Level 4" autonomous driving. It's meant to drive only on safe routes for which the carmakers have already tested their technology.

In theory, all self-driving cars should be classified as Level 4 right now, because I don't think any of them is good enough for being classified as Level 5.
"Head to head" is an unfortunate way to compare automobiles, like playing chicken.

Probably the Cadillac. I have no expectation of a Tesla or anyone else having a 100% autonomous vehicle during the lifetime of current cars, much less one that it retrofitted to current hardware.

I suspect there’s a market for those parents who travel with work or are otherwise away from home for a time wanting to “drop in” and see the kid.

Much the same logic as the market for indoor security cameras from Canary/Nest/Arlo et al, and those seem to sell well enough. I know several colleagues who use a Nest in this way, for families and pets.
I'm one of those idiots who always forgets to bring reusable bags but since they passed similar laws in my city, I've cut down on bag use, sometimes just carrying all my items. Laws like that help because groceries no longer assume you want bags. Now you have to make a decision. So even when I do forget and have to buy a bag, I ask for the bare minimum and the clerk just stack my bag as full as possible. In the past, I think they would have left a lot more room.

I guess these laws have an impact just simply making us make a decision on the number of bags we want to be charged for.
I'm possibly starting to age out of the target market, but Snapchat has done a great job of getting me move to Instagram stories for my "social media" type content (vs. individual targeted stuff, which Snapchat still works all right for).
The fact that --help can actually DO something makes me quite upset.

That means npm is causing side effects even before reading what the user wants, or is blatantly ignoring the user's request
As the article notes, current systems are maybe Level 2ish but the guidelines are vague enough that it's hard to say for sure.
And if social media companies were legislated out of business people would figure out solutions to staying in touch and we'd avoid all the zombies we're creating [1].

Atheism is a category. Aka those without diety is the literal definition.

Just as it would be wrong of me to say "All deists believe in the same god, that is why they don't take belief in different dieties seriously", its wrong to attach belief in responsibiliity to a category like atheism.

An example of the disparate groups that qualify as atheists:
- Antitheists
- Nihilists
- Some Agnostics
- Some Buddhists
- Some Stoics

Etc....

How you arrive at "atheism which basically means follow nothing" being attached to a category is beyond my ability to understand.

Have to agree, the recent update is a head-scratcher. They made user stories considerably more confusing to use, and these same user stories are what made Snapchat successful and exciting to begin with.

I really think they should work to bring back the daily city/event stories too. For those that don't remember, they used to aggregate the biggest events and city stories on a daily basis and provide those front and center. Was a really unique way to experience a city across the world from where you are! They've since gotten rid of this, and moved it into a hidden "SnapMap" feature which is easily missed by many users.

> Are you going to read and evaluate them all?

Elsevier doesn't read or evaluate them either. They use academic peer reviewers who don't have any equity or salary from Elsevier.

> No, you want some sort of structure where you have people you trust do some sorting.

None of those people are paid by Elsevier.

> That's what the publishing system does. (Plus the editing process).

No, the publishing system provides brands. If Elsevier actually curated, hired and paid a fair salary to the peer reviewers and researchers who actually performed and evaluate the research I think you would be right. But it still seems to me they're purely a marketing middleman that takes public funding and public laborers and turns a private profit.
The reason Om cites as why Facebook won't change is similar to the reasons companies don't change in response to disruptive innovation, as described in Christensen's "The Innovators Dilemma." Big companies are too invested in a successful business model for them to easily switch to a new one overnight. Even if Zuckerberg grasps the threat to FB's brand posed by fake news and smartphone addiction, his company is streamlined to operate the way it always has been. The best he can achieve is short term fixes and lip service. Solving these problems would require Facebook to value something other than people's attention. But doing that would cannibalize their advertising business.
From my experience relying on the slider means you miss a lot of options. For example, some hosts have huge differences in pricing depending on the length of stay. I have found weird results where it's been cheaper to rent for a month than for 2 weeks at the same property.

pipenv combine pip and venv. It's not just about activating. If you install, it will create the virtualenv if it's missing.

It also, like pew, opens the virtualenv in a new shell instead of activating the current shell. A much saner approach.

The UI is also more user friendly: one entry point for everything, pretty colors and icons, auto-correct of package name, and so on.

Using Pipfiles, instead of requirements, are generally a better experience than requirements.txt since it contains dev and prod dependancies and allow separated dependancy pinning, with file hash.
With aggressive driving, it's very easy to move braking loads into the friction brakes, making a 100% loss. Even when you cycle energy out of the battery and back in via regen, there are losses (to heat).

Driving carefully in my LEAF, I can get 4.2-4.5 miles per kWh. Driving like an ass, it's easy to get that figure down under 2.
