Ah good point, I thought this would work in our favor. Curious if it works in theirs. Thank you for pointing it out.
I’ve always kind of had a problem with the whole idea of describing a loan as ”predatory”. I know it’s the accepted vernacular, but it’s really a loaded term. “Predatory” removes the borrower’s agency and reduces him to a helpless gazelle, walking around the savannah one day when all of a sudden a “predator” jumps out and suddenly he has a loan! Is this really how it works? You wake up one day to find a “predatory” loan preying on you? These loans aren’t walking around attacking the general public. Yes, they’re marketed unethically. Yes, they take advantage of the borrower’s lack of financial education. Yes their repayment terms are usury and unfair. But they don’t stalk people and force them to become borrowers. I think someone should come up with a less inflammatory word for these loans. Maybe “exploitative loans?”

Somewhat, but I feel better understanding that time/code was spent understanding the problem better, and with that knowledge I'm now able to make something cleaner/simpler/more concise.
I first encountered this kind of shopping center in the suburbs of Philadelphia. Main Street at Exton struck me as incredibly strange - it's a strip mall dressed up to look like an urban downtown, right down to parallel parking spots on the street. Once you do park, it is actually fairly walkable.

A couple of years later, after having moved to Philadelphia, there was something I wanted to grab at a store in Main Street at Exton. There's a regional rail station a half mile from the shopping center, so I hopped a train. The absurd thing about this particular arrangement, which otherwise sounds like a great way to connect nearby markets, is that there is no sidewalk between the train station and the shopping center. The station sits where a major local road meets a major highway, so one way or another, you're crossing six lanes of traffic to get past the local road, and you have to cross two major highway four-lane on/off ramps as you go under the highway overpass, walking along a beaten grass path with only a curb between you and the traffic.

Exton Mall's another mile up the road, and while there's sporadic sidewalks between the two malls, I've never bothered with that walk.

Given the proximity of this shopping center to public transit, I don't think it's a big leap to suggest that the decision to exclude sidewalks was at best a classist choice, at worst a racist choice.

I live in a part of Philadelphia that's unusually pedestrian friendly, all things considered. I can walk to pick up groceries (except I get those delivered), the hardware store, coffee shops, restaurants, galleries, all manner of everyday things that, when I lived in the exurbs, I had to hop in the car and drive anywhere from 5-30 minutes to get to, and it's fantastic. We've also got more methods of public transit than almost anywhere in the world (not saying the coverage is great, mind you), and I've been here long enough that despite all the challenges that come with living in an old urban center, I hope I never have to go back to a suburban lifestyle.

It was clear from the moment I pulled up to "Main Street" that these psuedo-downtowns miss the point.
>> sometimes provide information to Boeing to help them compete against Airbus, for example.

I've always wondered how that works so that employees dont know about the gov involvement. I suppose they could hire a "consultant", but someone in the company still needs to know dont they?
>Given this, I think it's reasonable to demote FP to the level of "feeling", at least in general conversation. Discussions within a certain language community, or in the context of a book or article, are a different matter of course since a formal, contextual definition can be given there.

This was largely what people thought of mathematics before euclid formalized geometry. An exact definition exists for FP as it did for geometry and like geometry we will instantly recognize the definition of FP when someone finally decides to translate our intuition into formalization.

On the other hand I understand de data model of git and can't to the most basic shit without looking up which invocation I need via search engine/man pages.

The problem is they're using bad heuristics. Just because a service runs 24 hours a day doesn't mean it's using a significant amount of battery. The harder problem is, just because a service uses a significant amount of battery doesn't mean it's doing nothing useful.

If I want my email app to download my emails as they come in because I'm on a slow network connection, I want it to do that even if I get a lot of emails. Especially then. Even if that means I have to charge my phone every day instead of every week.

What they should be doing is using a blacklist instead of a whitelist. Not because they're actually going to be able to blacklist every misbehaving app (though they could certainly catch the most popular offenders), but because that's how you get developers to change their behavior.

If everybody is restricted by default then there is no incentive for bad developers to do better. They get restricted, they weren't going to get whitelisted either way, so they go on making a wasteful app. By contrast, if making a wasteful app could get you blacklisted and restricted when you wouldn't have been otherwise, well now you've got a deterrent. Meanwhile they wouldn't be defaulting to breaking well-behaved apps that are designed to efficiently run all the time.

This is one of those things where I wonder if we are just so inured to the idea of currency that we cannot conceive of people that don't work that way. It's really hard not to bring anachronism into history and try to put yourself in the mindspace of people who didn't necessarily have the same unconscious framework of thought baked into them.

> used a rotary phone to navigate a phone menu

That’s impossible. Rotary phones use pulse dialling exclusively, but phone menus/trees require the tone dialling of push button and touch-screen phones. I have never heard of any phone menu/tree, even at the dawn of their implementation in the late 80s when rotary phones were still common, supporting pulse based dialling.

> So they attempted trickery to pay them less as "independent" contractors

An Uber driver is the very definition of an independent contractor. Many drivers also drive for Lyft. How can they be “employees” of Uber while also driving Lyft? Or doing Door Dash?

If Uber drivers were employees, they would have to work where and when assigned. As it is now, Uber drivers come and go as they please.

I am not sure how an Uber driver is any different than a freelance journalist or musician.

Many (if not most) ASTs, especially in batch compilers, do not preserve comments, whitespace, or even all of the actual syntax. Even the diagnostics information you're referring to are insufficient to reproduce the whitespace.

Further, what Roslyn does is quite interesting even on top of preserving all of that. It does so in a way that lets it incrementally re-parse parts of the program without touching the rest- including position information for the rest of the file after the change, which has all shifted to match.

None of this was standard practice anywhere when Roslyn was designed, though it's starting to be picked up in other projects since.

preamble: I think game theory is super useful and applicable.

It's when people hear an analysis and remember experiences in their past where, had they applied that same analysis, they would have been completely wrong and maybe even achieved a much worse outcome for themselves.

Another take is that some situations have chaos-like properties when approximation analysis is applied to them. The diameter of a ball isn't going to explode several orders of magnitude wrong and into negative space.
Eh indeed, and it could even be that schizophrenia (whatever its "base principle" is in the brain) exists in some people born blind, but presents itself in such a different way that it's misdiagnosed for something else (so categorically, that we already have another name for it).

But I think it's really worth investigating. Could yield important knowledge and may lead to new forms of treatment perhaps.

I'm confused. Why would it be interesting for a startup to be earning $4k MRR? Are all the points because of the transparency?

< $48k/yr with someone working even 20 hrs/wk is a worse proposition than getting a mid-level 9-5 job in the US.

I don't think it'll fly, here is why:

Our product is a XMPP client, which can't work if it is not actively running in the background, so we were working with making apps run in background on Android for over 10 years, since version 2.0.

The trend is clear: with every update, we get more restrictions. Not only bg services are killed off from memory by aggressive memory managers of crappy phone vendors, Google themselves push developers to rely on proprietary FCM services. The writing is on the wall, and one day background services in Android will simply cease to work, all in the name of better battery life and customer care. So this OpenPush service will be short lived, it'll likely be disallowed to work in this form in Android 12 or 13.

The only proper long-term solution here is an anti-monopoly legislation, that would make Google allow Android users to subscribe to a third-party push notification service. Such service is, actually, a relatively simple: current FCM is just a modified XMPP connection that a phone keeps, and it will be easy to replicate and deploy.

Apple is guilty of this, too. A proper anti-monopoly legislations should target them as well, and not only make them allow third-party app stores, but third party push notifications as well.

This control of push notification services and restriction creep that occurs on both platforms makes Google's and Apple's grip on their respective OSs much tighter than Microsoft's grip on Windows ever was. This tyranny must be stopped, and I don't believe it can be done without legal action, by technical means only.

If you have income and you're young, you can afford to take risks. Big tech is disproportionately represented in SPY/QQQ so if we're in a massive bubble it's all going down anyway.

I consider active investing to be a hobby. I get a kick out of seeing earnings reports come in from companies I'm invested in. Again, I've dramatically outperformed SPY over 10 years and the gains have nearly secured my retirement as someone in his early 30s.

I occasionally hedge with SPY puts or gold calls if I think we are in an actual correction. If it's sustained I would do that over selling.

Insurance is about risk pools, if Level 5 becomes a reality the risk of a human driver will go up, and has more and more people adopt level 5 (which they will contrary to what people on here think) the number of human drivers to spread that risk over will go down, small risk pools with increasing amount of risk means higher premiums

The problem I have with this as a solution is that the environments where custom kernel modules or kernel modifications in general are being used as a layer of security are already largely customizing these threats out.

Disabling kernel module loading, or restricting it to signed modules shuts down many of the vectors without using out of tree code. There are many security switches that are generally left off in widely distributed kernels that provide deep protection when you don't need to support everyone's project and app.

For specific distributions like those listed this is fine, but those also generally aren't used in higher assurance environments either.
