I think perhaps the more interesting question (more interesting than what you label something) is how much functionality you develop before trying to get people to actually use your product.

At least in the space I’m working in (issue trackers) we had to build quite a lot of functionality up front to get people to seriously test out our product [0]. The reason being that we’re in a space where we’re convincing people to switch away from existing solutions so they’re not likely to overlook glaring omissions in functionality.

So the question you should be asking yourself is - how much functionality do I need to build to get meaningful feedback?

It's not a single app. Apple and Google provided common APIs, but there isn't an Apple/Google "app".

There are lots of different legal requirements, and the app points towards the local testing regime for example which is different in every country.

I self-hosted Matomo for a year and a half (and took over the AUR package for it and improved it in the process). It was no trouble to run, but I ended up uninstalling it late last year, for a few reasons: its interface is painfully slow (and that’s nothing to do with my 1GB/1 vCPU VPS—I’ve interacted with a decent-sized instance at innocraft.cloud and it was similar), and I seldom looked at it, and I couldn’t think of any way in which anything I found in the analytics would change my behaviour, and server-side analytics are good enough (better on some ways, worse in others), and I value speed. So all up, I figured: why am I slowing all my users down with this 50KB of JavaScript (of which I frankly need less than 1KB), and why am I keeping this software going?

So now I pull out GoAccess (which reads the server logs) from time to time. I find that my Atom feed is the vast majority of traffic to my site, which Matomo couldn’t tell me. I should implement pagination on the feed and see if that helps. (Or limit the number of items in the feed, but conceptually I rather like everything being accessible from the feed. Wonder how many feed readers support pagination?)

It serves the purpose of labelling a process of deliberation over a set of choices. Whether that deliberation is deterministic or not is a red herring.

The rabbit hole goes deep here. Formal concept analysis is essentially the study of certain galois connections on lattices derived from relations on sets. You can generalize relations to profunctors on categories and galois connections to adjunctions.

In addition to the other comments about not forking, I will add this disadvantage of forking:

I have thought in the past that if your forking technology is a branch in git, you can still merge changes (or cherry-pick, etc.), so all is not lost in terms of creating features or fixing bugs which should affect both platforms. However...

The problem there becomes refactoring. If you're e.g. using Java, with e.g. IntelliJ, you can e.g. rename methods and all usages will also get renamed. That's good, and that feature doesn't just speed you up, it also encourages you to do the refactoring at all, leading to better code long-term.

However, if you have n branches, IntelliJ is only going to refactor the branch you're on. After you've merged the change into the other branch, all the features custom-developed for that branch will still use the old e.g. method name, you'll have to update those usages by hand, which is a lot of work.

If you keep the code in one codebase (e.g. feature flags, config file, whatever), if you refactor something, all the usages (even in code hidden behind the feature flags) will also get renamed.

That's an interesting idea. I should look into that when I eventually upgrade. A stubborn part of me left the monitors in landscape because I occasionally play games, but I end up never doing that on my desktop.

Because I prefer to use the same model of monitor when doing a grid, so I don't think I want to add to my existing setup, because my monitors are discontinued, and they're displayport only for 4K60.

> your electronic devices confiscated and searched

I don't know where on earth you got that from. The police can and do need to get a warrant in order to confiscate or search the accused person's devices or belongings. The warrant needs to explain with probable cause, why those specific devices/belongings are relevant to the case and need to be searched. If the cops can't provide probable cause for searching a device, they aren't allowed to do so.

> the proponent of a claim bears the burden of proving it

Hence why I said that it is the accuser's responsibility to provide any and all relevant evidence. You are going one step further and saying that the accuser should give up all claims to privacy, in the entirety of their life. Ie, if I want to press charges against someone for robbing me in a dark alley, I need to allow the police to search my house. This is a ridiculous way to structure any criminal justice system.

I've been doing user interviews in the morning; it's been working quite well so far. I'm in CA and a lot of my customers are on the east coast (NYC), so waking up a little early to respond to emails, DMs, etc., has meant I ease into development around noon. I also made a Slack team for myself and users when I started the project, so if I'm in the middle of building a feature and on the fence about whether or not to build, I'll poll the Slack group for some quick feedback. IMO Slack is just low-touch enough to be background noise while code wrangling. There's been a lot of excellent use case comparison and unprompted feedback from that community as a result.
Show HN: Train Neural network racecars to drive around F1 racetracks
I am inclined to agree, but I think we need to be careful not to paint the "decentralised" approaches as perfect. Neither solution is perfect, as both make different trade-offs. I share your privacy concerns and whether it's a "bad idea" or not.

The UK has no plan to make the app "mandatory", and they are well aware of the demographic issues that would cause, especially with large areas of elderly populations. That's why there's such a focus on the traditional approach to contact tracing.

RE decentralised vs centralised, the trade-off isn't so simple though in my view - the decentralised app requires the creation of a list of the "infected", which is synced to everyone. That means those who get infected suffer a fairly large "loss" of privacy compared to those not infected. The centralised approach "averages" the two by not broadcasting an infected list. It isn't hugely difficult to use time-based correlation with a calendar or diary to work out if a given person was infected etc, if you have access to the list and database (which we should assume in a threat model people have). The question is if this is a design goal or not.

In addition to the app is traditional "public health authority" contact tracing. That in itself is very privacy-invasive though, and I think people are ignoring it in favour of talking about the app - collecting names and contact info of everyone someone was in contact with, storing this into an IT system, then contacting them etc. Data retention concerns etc and privacy risks here seem significant, yet there has been more focus on the apps than on this traditional approach.

> U.S. overall rates of COVID death are dramatically lower than the UK and Sweden

Is 10% less than the 2 worst european countries really worth applauding? Also 10% isn't dramatic in my book.
Average US death rate for the last 7 days is still 5 times higher than France for example. [Edit: this is bad metric, see comments below, my bad.]

> so they went for flattening the curve which they succeeded with

We cancelled a bunch of routine treatment and surgery in order to provide surge capacity. We converted existing wards into new ICUs. We had to take unqualified student nurses and convert them to temporary nurses[1], we took doctors from their specialities and got them to cover other work. Finally, we stopped admitting certain groups of people to hospital altogether. Look at the death rate in care homes.

> They got away with 40,000

That number is for people who died after having a positive test. Many people are not being tested, so there are many deaths of people not included in that figure.

At the moment we think the true number is at least 50% higher, so the real number is 60,000.

And there are different ways to count death. If the UK used the same method to count covid-19 deaths as it does to count flu deaths we'd see over 100,000 deaths.

[1] ...and we said we'd pay them, but now they've finished a lot of them are finding that they're not going to be paid.

This is a great example of why this is a tricky area to legislate.

On the one hand it seems crazy that Basecamp’s business model should be significantly impeded by Apple’s rules.

On the other hand, we need some way to prevent people from just installing their own platforms.

Given their track record, I don’t expect a gaming platform from Facebook to be benign.

But let’s assume it is.

If Facebook can install its own gaming App Store, so can anyone else.

And that opens the door to all manner of bad actors who distribute gaming platforms aimed at addicting kids, extracting personal information, etc.

They have long failed to enforce their terms of use against Trump's account despite him posting tweets that violate them, despite other accounts that posted the same text verbatim having the tweets removed and/or being banned from the platform.

I can't think of any high-profile liberal politicians who have such a blatant disregard for the rules of the platform, so that must be what you're referring to, right? Or is your contention that rules like "don't use our platform call for violence" are themselves political censorship targeted at conservatives?

1. You ignored more than half the post you're responding to, and sidestepping the question. Can I assume that you think police killing 5 children and burning 61 houses was justified? A simple "yes" or "no" would suffice.

2. It's clear you're more interested in blaming anyone other than the cops than you are in preventing children from dying or houses from being burned. That's a serious ethical problem you have there.

3. If we're going to play the blame game, then surely MOVE and the police are both to blame.

They're not. What version of "every country" do you have in mind? Most other countries also failed at contact tracing early on. The only country in Europe that had and used effective contact tracing was Germany. Almost everywhere else it has made little or not contribution.

If you look at the epi curves then the UK, France, Spain, and Italy have had basically the same outbreak (France a little less). So there is no need to wonder why the UK is special because it isn't. There is plenty to say about which European countries responded well and which didn't and why even Germany's response was markedly inferior to countries like Vietnam but that has to start from a data driven perspective that doesn't pretend that the UK is particularly special.
I agree with you. I have a degree in electrical engineering and use that book to quickly remind myself how something that I haven't used in a long time works and get an overview of practical do's and don'ts.

Segment alignment. Not read alignment.

Large model memory allocators would allocate memory on segment boundaries. This is more or less essential if you need to use more than 64K of memory in your program.

An 8-bit paragraph size (rather than the 4 that were used) would've forced all segment allocations to 256-byte boundaries, so that's where the fragmentation issue comes from.
