Madison WI still uses salt, but we also use a lot of a mixture of sand and salt, which looks like pure sand from a distance, and liquid salt solution sprayed directly on dry roads before snowstorms when possible. The city claims that both of these methods, while not eliminating salt, greatly reduce its use.

The city also puts out piles of sand-salt for residents to use, so I usually grab some at the start of the winter. The mixture is easier to store than either sand or salt by themselves. For instance, a pile of salted sand won't freeze solid.

Salt works by freezing point depression. You can throw salt on sheet ice and it will melt the ice, until it gets too cold. Calcium chloride works to even lower temperatures.
Apple can design custom everything and has the economy of scale to justify it. The PC space is also more competitive, Apple managed to associate their brand with luxury and charge a huge premium for their hardware, a laptop with equivalent specs would struggle massively to sell at the same price when you could purchase similarly powerful laptops for half the cost that would run the same software.

At this point Apple can design any gimmicky piece of hardware, stick their logo on it, sell it for three times the price of equivalent third party products and still run out of stock on launch. You can't beat that.
Hi! I'm excited to share a preview of natto, a spatial UI for writing and manipulating JavaScript. It's kinda like a mix of JS playground, script runner, API client, JSON viewer, and datavis tool. Here's a demo video https://twitter.com/_paulshen/status/1370404362325876737

If you're interested, I recommend checking out the tutorial https://natto.dev/tutorial to get a tour of the features. The "coolest" feature right now is the ability to drag a column header out of a table pane.

I get quite excited thinking about the "future of code" and think natto explores some ideas in that direction. I'm actively working on this (have lot of ideas) so stay tuned for updates. thanks!
And that's the reason.

OEM are very risk averse. They only produce cookie cutter designs because most of their buyers themselves look for most casual buyers.

Create sharable links with different images, so you can share the same article multiple times, e.g. on twitter keeping your feed nice and clean.

For those interested in the details, it renders an html page with custom metatags and immediately redirects to the target. Redirect happens in js, so crawlers actually display our metatags vs the target ones. It's just a hack I've tested a while ago, a couple marketer friends liked it and so I decided to make it into a micro SaaS.

If you want to try it out, I recommend to have a blog post handy. (also, credit card are disabled, but I like to keep the landing page "final".)
Microsoft experimented with bold ideas with their surface series. They have fantastic displays (3:2, 4K, multi touch), keyboards, and touchpads. But they have the same issues as Apple’s devices, you cannot open the machine and change components, and the I/O are a bit limited (USB 3, SD, USB-C, propriety port for charging).
Kicking out Apple manufactoring won’t happen, because it’s actually dangerous to Chinese manufactoring. Apple is currently one of the only companies who could deal with being banned in China. It won’t be cheap or easy, but Apple could move manufactoring. They already have a deal with an Indian company who makes older iPhones for the indian market.

Apple is also one of the few companies who can either absorb the additional cost or even pass it on to customers.

But IF Apple was to move manufactoring it would set a dangerous precedence for other companies and potentially start a supply chain completely outside China.
Well, they only "should be able to have them" to the degree that there's a sufficient market for someone to make and sell them. There are no guarantees that the product you want to buy is one for which there's a sufficient market to sell.

It's odd to say you don't need docker when you use systemd to solve a lot of the same problems. It's not that you don't need what docker provides, it's that you're getting it elsewhere. It's not like systemd is far less complex, either.

Docker containers are really just bundled-up processes. Once you move beyond things that come in statically linked binaries, it's nice to have a common packaging format, especially one that has such an expansive ecosystem and buy-in from every major cloud provider.
I think you really hit the nail on the head. Software engineering is quite hard, it's also a very broad field now, and you have to love it to do well.

I'm not sure I follow. The fact that a nuclear grid doesn't require storage is precisely why it's so much better. In order to make renewables viable we'd need to redirect a huge portion of our storage capacity away from electric vehicles and towards grid storage instead.

> That is, if you assume we'll need nuclear power, you're basically assuming we're not going to solve the climate crisis.

How on earth does this make sense? The country that has come closest to solving the climate crisis (France) is heavily nuclear. Their carbon intensity of electricity is 1/7th that of Germany.
That's very helpful and adds a lot of clarity.

You can tell from the code that the "exploit" here is abusing keychain sharing.

iOS has a feature where you can pack a surprising amount of generic data into keychain storage, intended for passwords or auth credentials.

iOS also lets app developers opt-in to shared credential storage, so that if you have multiple apps, the user only needs to login once. Here's a blog post on how to do it: https://evgenii.com/blog/sharing-keychain-in-ios/

A little-known quirk of the iOS keychain is that it persists across app installs. This is useful because if multiple apps share credentials in the keychain, you don't want uninstalling one app to log you out of other apps.

If an American company tried this (looking at you Branch.io), would it be banned by Apple? Maybe? That seems to be the controversy here.

Perhaps Apple needs to rethink its keychain sharing API and make the user opt-in to credential sharing.

Also a keychain management tool would be nice, so users can see what data apps are permanently storing on their devices (even if the app is uninstalled).
As a student most of the way through a Java course, I'm wondering what Java is still used for. Java applets are dead, Android is moving on to Kotlin (apparently Google got in legal trouble with Oracle even though Java is "open source?"), and I can't think of any desktop applications that use Java anymore. Java is supposed to be able to "run anywhere," yet C++ is more portable because it doesn't require the JVM to run.

Yet clearly I'm mistaken, since Java is still one of the most popular languages.

Edit: also please help me understand - do I have to pay for a license even though Java is open source? Is this normal for other languages too?
I have been working on SceneRadar.

This tool displays you timestamped alerts (nudity, sex, violence or gore). So if you plan to watch a film with your child, your parents or other conservative relatives - you know when the danger scenes are going to hit you.

The answer to 0 is "call your local permitting office". For real, these people are usually really nice. At first they will probably talk over your head because most of their work is with seasoned developers but as soon as they understand you are a noob they can usually talk you through what you need to do.

System76 is probably one of the least bold laptop manufacturers because they can't afford to be. As other comments have noted, much of their hardware are largely rebadged devices from other manufacturers such as Clevo, because the main selling point of System76 appears to be the software experience and hardware integration.

If you want great design that matches a Mac (overall, better in some areas, worse in others), look at the flagship ThinkPad models, Microsoft Surface devices, etc. There are many laptops that have "standout design features" such as convertible designs, novel display and input options including pen-and-touch, etc. If anything, I think Macs lag behind in these innovations, although they have other benefits.

Definitely depends on the specifics of the individual policy, many policies (that I've had) don't list winter tires as a requirement for wintertime, but sometimes you can get a discount on your premium for having winter tires if you live in a snowy area, which then would have a tire requirement in the policy.
Exactly. Whether a major corporation technically could do ”the right thing” at the expense of their own bottom line is a moot point, and it’d take a fundamental shift in our society for that to change. Rather, getting them to act in a way that’s beneficial to as many people as possible is a matter of economic incentives and regulation.
I hadn't even contemplated that. Thank you. That's an important use case.
Oracle's administration interface is horrible. It's an obtuse nonsensical hierarchy, probably specified by someone non-technical writing a requirements document in a vacuum. It'll take you an afternoon to figure out how to get your instances set up, upload your initial image etc. Also your instances will always be behind NAT (having internal IPs), which is odd.

Its redeeming feature is having a free tier that isn't Google. The problem with using Google's cloud is that if someone hacks your account and runs up infinite charges as a personal user, you can't file a credit card dispute without disrupting your entire relationship with Google.

The cloud market still has healthy competition - eg Linode, DigitalOcean, Vultr, and innumerable smaller companies. Patronize them, rather heading than to a different behemoth.

> "We don't need Docker" was also on the front page of Hacker News.

To be clear, the platform does not support "short selling" of the shares in another member. So, there is no effective way to deliberately drive down the reputation of another member.

Shares are traded in a fixed size of 100. Each BUY transaction increases the share price by 0.01. Each SELL transaction, reduces the share price by 0.01.

When you join the service, shares in your profile become available to trade by every other member. Members discover each other primarily based on services offered/needed. Today, if you like someone on a network, you might choose to "follow" or "like" them. We offer an alternative, whereby you "invest" in them.

A follow or like from you to someone else makes the connection and allows you to view their network activity. An investment on SELLFF does the same "and" allows you to benefit from any upside in the value of that investment. As the person you invest in goes up in value, so do you. Not a bad situation really.

Anytime you like, you can BUY or SELL more shares. The exchange is open for trading 24 x 7.
I wonder how that fits with the Ministry of Industry and Information Technology's recent notice to 136 companies to stop their excessive collection of user data by March 17 or cease operation: https://www.miit.gov.cn/xwdt/gxdt/sjdt/art/2021/art_7e5c3fa7...

Maybe the kind of collection CAID enables is considered acceptable? Or it's just a case of different departments planning past each other.
I've found that places exempt from building codes are much more common than places exempt from health code. Be sure to read up on local plumbing, waste water, septic, etc. code. They will often dictate things like how big the septic system needs to be, how big pipes need to be etc. Generally good rules to follow if you want such a system. If you want a legal outhouse or composting toilet and/or grey water setup, there are very few places in the US which allow it so be sure to read up first.

Roll down to your post office during off hours and count the number of trucks. I live in a very small city (people used to SF or NY wouldn't even call it a "city") and we've got dozens.

Not sure where you're getting the 1000Wh/mile number, but if it's from "normal driving" it won't apply. Mail delivery is stop and start, which is much worse. (If regenerative braking was 100% it'd be fine, but it's nowhere near that.)
> I don't think this a particularly fair criticism. Deicing salt works by absorbing moisture as it lands, before it can form a sheet of ice. It's useless if it gets wet before you use it

Over here deicing is frequently done with brine because it sticks better to the road and doesn't get blown away, so I'm very skeptical about the salt being useless when it's wet.
What will make it tough is that our roads already get destroyed every winter without the help of spiked tires.

In MN the entire summer is filled with road construction already. I wouldn't be that thrilled about switching my tires 2x every year either.

The business success or failure of a movie is entirely determined by how much money it makes

Even without your movement of goalposts, a movie can still be successful without being in China.

The most successful movies in history were released, and massively profitable, before China's market opened to the rest of the world.

To maximize that success (or even to be considered a success), you must publish in China.

This is simply false. There are plenty of successful businesses, movies, video games, and other enterprises that never touch China. I hate to break it to you, but China is a non-factor for the vast majority of businesses on the planet.
Don't dense urban areas tend to have tall buildings that block the sunlight?
Exactly. My area gets snow 3-4 times per year, usually less than a foot. It is often gone within a couple of days. Our worst storm this year (roughly 15" of snow), the roads were cleared within a day or two. No way is it economical to buy snow tires; and snow tires damage roadways.

Do you have an example of a commercial that shows the car being advertised performing unrealistically in a collision?

I'm curious because most of the commercials with car collisions I could find are actually safety PSAs, not commercials for a specific make and model.

Aside from those, I found some examples of a brand showing the aftermath of a collision (very briefly) in an ad that skirts the line between being a PSA and a testimonial. Interestingly, most of these were from Subaru.

In any case, that's still quite far from the phone commercial, where the phone is put into a situation that voids the warranty, but no physical damage or any indication thereof is shown. A comparable car commercial would need to show a car in a collision (or compromising condition) that performs unrealistically and ultimately gets away completely unscathed.

My intuition would be that most car advertisers wouldn't want to associate their vehicle with such a scenario, nor set unrealistic expectations around safety critical product features, outside of maybe product placement in a James Bond film.

So, I'm very curious, do you have any examples of comparable car commercials that you could share?
This is a very simplified way of thinking about it. Costco manages to be profitable while paying more than the average to retail workers in an industry with thin margins. Whole Foods managed this too until it was acquired.

It's funny how the US is often presented hyper innovative, and economically dynamic, while at the same time it is claimed that basic issues like universal health care and workers rights - problems that are solved in many other developed countries - are intractable in the US because of "thin margins" or "the deficit".

Not directly related to the post, but developers should be aware that developer salaries will likely jump significantly this year.

The VC market is super hot right now - VC firms are being flooded with cash, and they need to deploy it. Companies are raising massive amounts of money at unprecedented valuations. A large chunk of that money is going to hire developers. The recruiting industry is seeing a huge surge in hiring in the past couple of months (source: I run a technical recruiting company (1)).

Because demand and cash available to hire developers has increased significantly in the past few months, but the supply is basically fixed, companies are offering higher salaries to attract talent. They have the cash for it.

Keep in mind that new money raised from investors will raise the value of your stock options, but rarely translates to salary increases for existing employees.
