On one hand, it’s fun to imagine what a truly full-stack rewrite of the internet would allow us to do, and what it would look like.

On the other hand, the current internet feels like a good approximation of the best trade offs for performance vs. usability in most areas, and I doubt a full rewrite would fundamentally change much about how we use the internet.
Wine doesn,t work great with Microsoft software, because they would take advantage of undocumented APIs, but W6W31 may be old and basic enough to work...

Title is somewhat misleading as we have seen air quality this bad in China. The US embassy in Beijing has recorded AQI > 700 in 2013 for example.
They may prefer it, but why should I?

Or they may never have thought about running on a different device. Why should I do the work to do it?

This was not done with the idea of portability, maintainability, or even good engineering practice.
They never asked me. Instead they resorted to name calling, personal attack. So understand why I don't feel inclined to continue this conversation and put more effort into it.
What could be more hacker-like than managing to string together a set of technologies like web browsers, HTTP/WebSockets and containers to let people develop apps?

If people can build apps on Google Forms + IFTT/Zapier or on Bubble.is etc then an entire programming environment plus database seems like it should be enough to build things on too.
The only way for Europe to get good tech companies is to create a business friendly environment. They seem unwilling to do that.

I doubt the implications are a primary motivator considering the US has been increasingly distancing itself from China anyway. Considering the makeup of academics it seems a lot more likely that you simply don't get to support republican affiliated talking points without having enough clout to survive a credibility attack.

Even if your evidence and procedures are correct you'll still be accused of something vague and indefensible like racism because your observations are somehow at fault for contributing to racist attitudes. As long as Social Justice, and by extension so social politics, focuses on belligerantly attacking any potential for dissent the situation is only going to gravitate more towards voluntary censorship.

I see that on netflix's info page it calls it a "documentary drama hybrid". That's a weird but accurate description, because as a documentary it's too biased and makes me feel that it tries too hard to push it's agenda to me. I agree with most of it's points, I deleted my facebook account several years ago, but they way this "docu-drama" represents its points makes me unable to take it seriously, because there's just too much drama in it.

> A half billion apps sound way more than needed....

'Half a billion' figuratively speaking is not much, if you account for all internal apps in enterprise (ex approval flow for weekly cafeteria menu). If there are millions of small and medium enterprise then there would be millions of cafeteria menu app.
This is the natural way, which most people would resent and reject. Screwed up incentives need to be fixed first.

We have been using Twilio and we're sending them hundreds of dollars a month. I'm about to drop it because of their 2FA requirement. Either they accept customers that know how to manage passwords or they don't. I don't give my phone number to ANYONE any more.
The simplest answer is that journalism relies heavily on credibility and BuzzFeed's brand has almost none of that as far as the public is concerned. If this was the WaPo or NYT they could probably get away with the usual "We'd tell you but that would be unprofessional."
I think the problem is bigger than that. Consider the NYC housing market. Even though there's almost no vacant real estate, rents are always rising due to the constant flipping of property. I say flipping since most of these purchases don't fundamentally improve the property in any meaningful way. Moreover, this continues despite the city having one of the highest capital gains tax rates in the US.

If investors had access to an alternative asset class that allowed them to realize decent YoY appreciation without undertaking risky construction, demand would cool down significantly. The end result (in the long run) would be sustainable property values and affordable housing for the middle class.

How automating memberships for businesses may transform our cities
Hey HN!

Thanks for sharing your thoughts with us before!

Our company Withfriends makes it easy to sell memberships for your business.

We started it after we learned that people want to become members of local businesses.

We learned that by building a prototype and seeing 1 in 20 customers choose to support a business by buying a membership as an upsell during checkout - enough to increase revenue for any business by 60%!

We then joined YC, believing we were onto something huge.

But there were bad signs:

A) Practically no local business sells memberships, but Patreon exists B) Kickstarter funded a company for this market, then shut it down C) Withfriends was growing ok, but not startup growth

Here's the real pain point, in a quote: "We're looking to sell memberships, but we don't want to do anything new. Can you help us?"

Local businesses are spread thin. They can envision a membership program, but have no time to set it up or execute any part of it.

The best way to serve them is to completely automate memberships by integrating with POS and e-commerce platforms that they use.

This requires a lot of hacking. The code for our Eventbrite integration surprised the Eventbrite team. We invented our IndieCommerce integration live on screenshare with a bookshop. And so forth.

Once we got used to this method, we've built the following integrations in one month:

Square, Squarespace, Shopify, TeeSpring, ChowNow, Toast, Eventbrite, IndieCommerce, & Upserve

Now any business can connect their POS or e-commerce platform to Withfriends in 15 minutes, and start selling memberships automatically. We generate profitable memberships from their data, insert membership upsells into their checkout, and automate discounts for members.

That's what we launched here today, and we think this will help small business thrive.

Isn't that port required if users want keyboards with true N-key rollover?
It sounds like she published an internal memo, somebody else leaked it, and the personal information was a fourth party's.
Lowering salary costs is one reason. The other potential reason is to vastly increase the talent pool.

If it's only about the first reason then management will cut salaries as deep as possible, if it's only about the second then they'll keep salaries at the same level and just change the job description. I suspect for most companies final pay scales depend on the weighting of two reasons. A lot of companies will try to have their cake and eat it too with location-based pay, but that approach will neuter the benefits of opening up for remote work, and its efficacy will only degrade further over time.
Something I’ve observed is middle management is doing more of the doing. That is to say, they are cutting out their (younger) subordinates. This is happening as they want to be in the best position to survive layoffs. I sadly have overseen the talent reviews aka lay-off rankings and I’ve heard from colleagues that this is happening at their companies too.
Where are you sourcing your stat from? It's hard believe that the millions of developers in China, India, SE Asia, East Europe, etc. are outnumbered by people in New York and San Francisco.

Cripes, US$150k is good money in London and that's a considerably higher cost location than rural Kansas.
Hmm, is it that hard?

Vehicle table -- ID, TypeId, Make, etc. (123, 456, ...)
TypeId table -- ID, Type (456, motorcycle)
Motorcycle table -- ID, HandleBarStyle, etc. (456, Low Rider, ...)
Automobile table -- ID, TrunkSpace, etc. (789, ...)

You can pretty easily add extra information to any id as long as you know where to look, and that can be a simple enum column to define the concrete type (and thus what data to grab). Its an easy enough join, isn't it?

The data modelling isn't the hard part really. Pulling it into an application in a nice way is probably harder. I don't often use languages with sum types professionally so maybe this is way off base but I don't see an issue.
the app needs a volume control. It's playing at the same loudness as the system's volume, which is not right for a background music app. It prevents you from listening to it while also listen to someone on a video call!
It will take years for markets to even out. Think SV vs rural Alabama. Paying market rate for the talent is table stakes. And I do agree, there will be less incentive to pay SV rates, so engineers living in SV will have to work even harder to demonstrate in the interviews that they are worth the money. Interesting times are coming.
This is exactly what I'm getting from twitter. My feed are the latest updates shared by the people I follow. I don't see clickbait, I don't see outrage, I have a curated feed aligned with my interests. It's true that about once in a couple of months Twitter decides to switch the order of tweets from the latest to the most recommended, but that's easily fixed in two clicks. The moment twitter removes the option to see the feed in chronological order is the moment I delete twitter.
> Being pseudonymous is key, but it's also the valuable part.

That does not seem to be they key on Facebook.
Recently I've been reading well-cited/exciting academic studies for edutainment. Since you want more intellectual content you might also enjoy doing the same. Of course, I skip most of the methodology section.

The Google Scholar widget has a new feature where you can save articles for later perusal. You can also subscribe to alerts with new academic studies on your topic of interest.

Youtube can also be way more intellectual than most people appreciate. Because of Audible, Youtube, HN, Marginal Revolution, and Google Scholar, I no longer have the patience for most articles on current events. I just keep abreast of the major developments. I definitely ignore most local news (shudder). I'm usually surprised when it rains out. Who cares.
Yet NYT still threatened to doxx Slate Star Codex.
No, it’s being driven by the lowest common denominator for engagement, which is distinct from personal preferences.

For a self-contained example, spam in large Facebook groups always rises to the top, because many people comment asking it to be deleted, causing the algorithm to show it to more people, some of which comment, until a moderator finally kills the post.

These kinds of side effects do not happen in a voting based system or a straight chronological feed.
Why not just say that then
I hope that person that leaked her memo had a ridiculous amount of social capital built up with her, though I seriously doubt it.

As previously mentioned, the library. The argument that one has to wait sometimes is superfluous. Anyone saying such a thing isn’t a regular library user.

Whatever is popular for the moment is just that: popular for the moment. It will pass. Almost never does a book need to be read the year it comes out. I mean, after all, if you value books, you value in-depth reading that provides perspective. As an example, when “Thinking Fast and Slow” first came out, getting it at even larger central branches was tough. Fast forward a few years and now every library has a few copies just sitting there. If one worries that if they don’t get it while it’s hot that it might be gone forever, then trust me, it probably wasn’t worth your time. The quality good books (both fiction and non-fiction) stay in the library system decade after decade.

If you aren’t familiar with intra-library loans, learn how they work. Super easy and you can get the books that are older, but not as heavily stocked, quite easily.

On tech books, get access to your nearest university, ideally a tech university library. Most will get you a card with certain conditions - and nearly all will let you visit and read forever with no questions if you’re professional about it. There are also private libraries (sadly rare) and some have good tech collections. Tech gets old and useless quick which is why most public libraries don’t stock stuff like O’Reilly. Which may be helpful to think about the value of spending one’s time reading something that will be DOA in 5 years or less. But if you are committed to a particular tech track or need for work, buy the book. That’s the cost of professional improvement. Don’t try to millennial your way around that. If you use ILL though, you can usually still borrow tech classics like K&R.

The modernist clamor for “the new” is dumbing down recent generations. Maybe what people really need to do is to read the existing books in the stacks so they can stop wasting time and money chasing the latest hip and trendy best seller that will supposedly cure all our ills.
Honestly, as a data scientist, most of the time when people move to the browser/cloud, I feel more like a michellin chef who's now been told that they now have to cook everything on a george foreman grill.

That I lease from someone else.

Any by the way, it's in their kitchen, not yours.

And the power cord is administrated by someone else.

In all seriousness, there's no fundamental reason why an IDE CAN'T work in a browser. Its just that I feel like we're constantly regressing and this is all just a subtle way for an external corporate to capture me so that I can't opt out. The amount of time i have to spend at work negotiating with other parties/budgets/silos/corps dealing with remote environments and software, when I could have done the whole thing in half the time with a 5k budget on a local machine...

It doesn't feel like we're moving forward...maybe moving back to medieval guild craftsman, because control is being taken out of my hands and I'm forced to sign up to respective software/environment guilds to do my work?
Lines of code on average is a terrible measure of productivity.

I’ve solved problems with 6 lines of code that took me a week to think of. Other days I write 600 lines of code.

I would argue that the former 6 lines I wrote is much more productive than the 600 lines.
I'm also starting to really hate this direction in software design where all buttons are either flat with the UI or hidden through some cryptic menu or swipe gesture or even worse, they're unavailable to the user, all for the sake of simplicity.

If you were to teleport 2003 me into the present, I would have no idea how to use most front ends of today's websites or smartphones.
Ubuntu 18.04 host but I ran it from docker.
My take-away from the abstract is that this is not about open science and reproducibility per se but about academic disciplines that have emerged to study those things.
Same here, but with US postal codes. Having grown up on the west coast I didn't realize some started with a zero until embarrassingly late in life.
This is probably way better achieved by a $5/mo VPS.

Benefits:

- way faster

- always on (presumably battery backed)

- you're not responsible for disk or hw failures

- better internet (faster, redundant connections)

- cheaper ($60/year vs $100 upfront)

- not fighting architecture differences

- comes with a public v4 address

- usually comes with a v6 address too

Downsides:

- data isn't under your control and is subject to military espionage

- your internet connection to move larger files to/from the remote device may not be great

FreeNAS is a good choice. Should last you for years, baring any kind of weird/unusual hardware problems (which aren't expected anyway). :)
I've enjoyed working from home for the past four years but have serious reservations about how well it would have worked for me at the beginning of my career. Though I came into the labor market with a good degree from a good school, there was so much to learn and much of that happened informally and organically while in the physical presence of others with more experience. Perhaps the nature or structure of work will adapt in such a way that those early in their careers will not be hampered by being remote but in the meantime it does seem like there is going to be a need for extra patience in developing younger employees into higher levels of productivity.
I want to love this. I leave these stations on in the background anyway and being able to change them like a radio station is a desirable feature.

It's missing 2 key features that will prevent me from using it and recommending it to everyone I know:

1) No volume control. You could argue this is more a failure of my browser, but it's easier if you just add a volume control. Bonus points if up/down arrows controls work to control it. Really, all the youtube keyboard controls would be helpful here.

2) YouTube sometimes detects my bitrate incorrectly and I need to manually set it to highest. I don't know why this happens, but it does. Let me change that somehow on your site. Even if I have to opt-in to seeing a full youtube player to set it, that's ok.

I would also like a convenient way to get this on my TV. I wonder which android TV devices can install PWAs now.
They'd pay the consumption taxes on everything they purchase.
More sophisticated analysis is required. You should look at the beta of Facebook at the time and determine whether the market reacted positively to the acquisition, or if the move was inline with Facebook's exposure to the market
I remember hearing that Nvidia were working on an audio spatialiser using their RTX hardware/expertise, but I can't recall hearing about it after 2018 or so, which is where the project I was working on that I wanted audio spatialisation for ended.
No. Vertica excels at being a column store database - a data model fit for analytics and OLAP. You should pretty much never use Vertica nor column stores for OLTP/transactional use cases.

It's not about the columns being wide, per se that is important in Vertica - although that is a benefit. It is about columnar storage and optimized querying, over row storage and optimized writing.

It would be the other way around - SQL Server or other transactional databases for that part. Actually, these days, SQL Server supports column store indexes on top of transactional tables- which gives you HTAP - hybrid transactional/analytical processing. A few other systems do this (Oracle too).

If you do HTAP, in a way you could even avoid using Vertica for data warehouse/OLAP use cases. Or you can build a separate dimensional data model in SQL Server and keep everything in there.

But if you already have Vertica, which is quite fast and good at OLAP queries on dimensional models, use it for that (enterprise data warehouse), and feed data from transactional systems in.

Productivity in this case is fairly simple to calculate = Cost/Duration.

You can factor in the time (presumably that’s paid for so you should have a real number) and cost of materials (On-site use historical or replacement cost) yourself.

Your points holds more generally though, especially when there aren’t clear prices paid.
I always thought it was simpler to explain by using the only trick linear algebra has: switch to a basis where your problem is easiest, then switch back.

Sylvester's law of inertia proves existence + gram-schmidt constructs that change of basis
Maybe this is another good reason to wear a mask!

Particulate matter in wood smoke is supposedly around 0.4–0.7 μm which which is a little bigger than a SARS-Cov2 virus particle at 0.1 μm so an N95 mask should handle both (not sure about paper surgical masks, almost certainly better than nothing for wood smoke).
If you can find a copy of this, I'd recommend it
"Conceptual Schema and Relational Database Design: A Fact Oriented Approach" by Nijssen and Halpin. They presented a richer model (NIAM) for designing databases than the ER model by Codd/Date, though CJ Dates book is useful to. Both of these are out of print now, but anything by Halpin or Date would be a useful addition. To design databases relational theory and normal forms are the language you'd need to understand - they're not very hard though seems they aren't as widely taught any more.
you can avoid nullable cols by using separate physical tables for each concrete type with surrogate PKs from a common sequence. these can be concatenated back together in a view (with no performance hit if you're careful not to hide indexes and predicate pushdowns). FKs then can reference the appropriate concrete table and in case you need an FK on some union you can use an indexed view instead.

I've used this approach for modeling entities that are polymorphic in object-land and haven't felt particularly underequipped - more robust indexed view support would be nice but that's active research territory (one of the hardest problems in computer science, materialize.io looks promising!)
>Imagine a system that allows third-party login (Facebook / AppleID / whatever) - then the account has either a username/password hash or an oauth token or some other kind of structured data.

What I've seen most often is you have to deal with account merging but lets say you do really want either/or...

Wouldn't you just have your third party tables (each with their own idiosyncrasies) and in your user table you'd have login_type and login_id columns? You know which table to hit by type using the id?
Strongly disagree, by definition it's the abuse that compromises the metric not the abusability. The distinction is important because it means that with a large and rapid enough rotation of obfuscated targets you can find out what you need while mitigating the bulk of intentional metric abuse.
The review process is a complete sham. If you honestly believe it’s a measure of your productivity and not a post-hoc rationalization based on a restricted promo and bonus pool I have a bridge to sell you.

Most managers will think an employee who spends 10 hours working and 30 hours schmoozing/promoting their work is more productive than someone who spends 60 hours grinding the tasks given to them.
