Classical equations of friction gives a constant relationship between weight and maximum acceleration from friction. And that applies fairly well to most pairs of materials.

But it applies less well to rubber. Rubber has significant natural adhesive qualities, so a normal force of zero Newtons gives a non zero acceleration. This adhesion dominates low weight acceleration. This is why performance cars tend to have larger tires. See dragsters for the logical conclusion. Without that adhesive quality, performance cars would prefer smaller tires for reduced air resistance.

The classical coefficient of friction model is one of "spherical frictionless cows in a vacuum" white lies we tell students to prevent them from getting overwhelmed by the hairiest differential equations imaginable.
You realize that we are talking about Google, right? These examples are hilarious, but also a little insulting to employees who actually need unions. Which does not include any Google employees.
Yes, it's a violation of sovereignty. It's probably illegal under those countries' laws. But it's legal for the US government to do abroad, and breaking other countries' laws and sovereignty to obtain intelligence is more or less the entire job of our intelligence agencies. This is the job of every foreign intelligence agency. Otherwise they'd just be investigative journalists.

Friendly countries spying on each other is super common. The US bugged Angela Merkle's cell phone! We do this. Everyone knows we do. They live with it, because they spy on us, too.

For good and ill, this sort of thing has been considered playing by the rules for decades. You can compare the response to the Russia assassination campaigns on British soil, which (when too public to ignore) created a big public response because that sort of thing was considered out of bounds previously. And the response to American kidnap-and-torture plots in Europe.

That's not to say we don't catch, try, imprison, and deport spies in the US and other countries do the same against us. But this is all part of a decades-long iterated prisoner's dilemma about what the "rules" are in international espionage.

I'd prefer 1000 times an AI that can explain to me why an opposite-colored bishop ending is drawish or why knights are more valuable near the center, and can come up with those and more new concepts/relationships/models on its own (regardless of whether we have given it the game rules or not), than a black box that is excellent at beating you at chess but you can't understand or trust. Adversarial examples (false positives) are supporters for this preference.

The US respects the rights people have, and the US gives tremendous opportunity. Is it perfect? Of course not. Are there issues that need to be addressed? Of course there are.

But to compare the US to a developing country is simply profoundly ignorant and a display of such privilege that it shows one simply can't even fathom what a developing country actually is.

I've been there. I've been all over the US, I've volunteered in homeless shelters in the US, I've travelled extensively in southeast Asia. The homeless in the US would be considered extravagantly wealthy in many places in southeast Asia. Southwest Asia too, I've been deployed there more than once.

The US is not a developing country or anything near it. We're the premiere first world country, and we provide opportunity beyond the wildest dreams many people worldwide can ever imagine. That's why the people in real developing countries generally want to come here.

Could not agree more. I hate the world we are building with SaaS type software where the user (me) has no control at all over versions, when/where, etc. I honestly think I may prefer the old "buy a shrink-wrapped copy" approach. Back then it was rare to run into bugs, and nobody ever "upgraded" me without me knowing and radically changed the UI. Maybe I'm just being grouchy and "get off my lawn"ish, but dang.
Actually, the cmd/ctl-z advice is actually moderately useful. If you type it immediately after the closing formatting character it undoes the wysiwyg formatting. (I'm not arguing against a way to turn the wysiwyg input window off, however.)
That's an extremist perspective against advertising (and seemingly only online ads) while ignoring the economics behind it. Call it what you want, but you know and understand the implicit agreement is ads in exchange for content. Clearly you're getting plenty of value otherwise you wouldn't be accessing the content in the first place.

But sure, some will have this position and it's relatively minor across the population, but you're starting to see more things behind subscriptions and paywalls as a result.

I don’t see how that data is all that valuable. There’s the inherent network effect of needing to install it to send/receive money from a friend who did.

But a surprising number of people will pay for instant transfer(almost all of that 300m probably comes from this), and the debit cards they get to take in a portion of the merchant transaction fees. They’ll probably be profitable off that, with p2p as a loss leader to drive installs

Not that it is necessarily true. There could be lots of data that some people are not aware of and that only senior people are privy to, but if that is not shared with the team developing the software then that is in itself not a great sign.

What are they using reddit for, though? Serious question. You can probably find 10x-100x the number of people who would use a site just for amusing cat GIFs vs. a location for actual discussion, but the users of each are looking for fundamentally different things. Reddit built itself on being a text-forward group of forums. The new redesign is, frankly, a dark-pattern horrorshow designed for eyeballs at the expense of deeper engagement. They're keeping old.reddit around for a reason.

> It doesn't seem possible to give "no explicit rules", unless you count "making an illegal move equivalent to a loss" as giving no explicit rules. Which doesn't seem like anything but word laundering.

The model is learning from game trajectories offline. Illegal moves will be assigned a very low probability because they do not appear in real games (whoever may be playing those games, whether in a simulation or in the real world). AlphaGo/AlphaZero did in fact mask out illegal moves in the MCTS tree search, but MuZero does not:

> MuZero only masks legal actions at the root of the search tree where the environment can be queried, but does not perform any masking within the search tree.This is possible because the network rapidly learns not to predict actions that never occur in the trajectories it is trained on.

And in ALE, all inputs are always legal, it's just that they may be useless and a waste of a 100ms turn. So for ALE it doesn't matter.

Now, for Go/chess/shogi, they generate the training data for the supervised learning part by reusing MuZero for MCTS self-play. They don't mention how legal moves are handled there; they might be masking out like in AlphaZero. You could argue that this is, in some indirect way, 'explicit rules'. But since the MuZero is already learning to predict moves' value and which moves actually get taken, I see no reason that the MCTS self-play couldn't implement an instant-loss rule without any problem or slowing down training all that much, removing even that objection.
Yes, but an adaptive format could allow static layout, while a static format inherently can not allow an adaptive layout.

> Is there any way that tweet could have been written that would have satisfied you, without actually agreeing to change course right away?

Not passive-aggressively suggesting that the problem is with the user and not the tool. "The goal is for workflows to evolve" effectively means "this is how it's going to be, you'll have to adapt (even if it's worse for you)".

My workflows have thankfully "evolved" to use different tools. Zulip and Discord both still use markdown input, and I no longer use Slack for anything.
> Would we still have Twitter? Reddit? Steam? Whatsapp?

How many of those broke old workflows to introduce new ones with no clear benefits?

But that's not the point. We're not talking here about broad services like Reddit, Twitter, or Steam. We're talking about something more akin to a libary. You shouldn't break interfaces in a library without a strong, compelling reason.

Do things need to change eventually? Absolutely. Do they need to change today, because someone decided that the old workflows they don't like need to break for everyone? Maybe not. There's perhaps some room between the two.

It's been my experience that business software often represents a deep investment in a given workflow. Sometimes to the point where businesses are willing to spend a great deal of money to preserve those workflows and integrate new things into them - MuleSoft springs to mind.

Which is not to say that you're wrong. It's absolutely possible to develop new, improved software that's better in critical ways. Sometimes people and businesses are willing to put up with temporary regressions and inconveniences to gain substantial improvements. To use the above comparison, I've seen artists invest the time in learning how to draw all over again in order to jump from paper to digital.

What Slack has done is take away what was a perfectly functional workflow for many people. This doesn't look like a temporary regression or inconvenience. This looks like a permanent, hard break without substantial obvious benefits for people who used the old workflow. Communicating with users in a way that telegraphs very clearly that Slack doesn't care at all is just gilding the lily.

The infuriating thing is that these would be some of the easiest possible features to add a toggle for. There's nothing wrong with liking drafts that float to the top, or rich text editing, but when a significant portion of your users is extremely upset about a tiny UX behavior like this, even if they end up being a minority, there's no excuse to not add an opt-out.
A lot of software doesn’t have to be “hosted” anywhere. The first question I usually have when trying out some web-based software is: “Why on earth can’t this be a native application that I just download and run? Why are they shoving a web browser and server into this thing?” With a cross-platform native application, you bypass the whole on-prem vs hosted question entirely.

I wonder how often the answer is simply “We know lots of JavaScript programmers and not a lot of Qt programmers.” Talk about the tail wagging the dog.

As a user, I strongly favor software I buy once, download, and run as-is, forever, untethered to the Internet.
Ask HN: What is a simple tool for parsing and analyzing log files?
Hi there,
I have a small app (frontend, backend, database) with <100 users. I would like to use my log files to analyze basic metrics, like for example
- number of requests
- number of comments created
- number of shared links
per unit of time.

All of this runs on one single server, no big infrastructure, no big data. I am unable to find a SIMPLE tool to collect my logs in some way, parse them, and visualize them in histograms for example.

I know there exist ELK stack, Splunk, Graylog and many others, but all these solutions are much too complex. Especially I do not want to spend weeks setting this up correctly. Further more, most of these solutions need an extra server for aggregating the logdata in some timeseries db.

I would be very happy if you know about any opensource tool which can do this job.
This is honestly a major contributor to the badness of software in general.

Ideal software would be continually fine-tuned and shrunk -- there'd be no bi-annual massive redesign, no change for change's sake alone. Instead of bored devs sitting around an office looking for ways to integrate $FRAMEWORK_OF_THE_MONTH and get those coveted resume points, a well-run project would make something work well and then they'd leave well enough alone, focusing only on bugfixes, performance, and other "boring" projects that don't make for big press releases. Changes to working products should be as surgical and minimal as possible.

A good compensation structure that would prioritize stability and consistency would pay an ongoing royalty to the relevant technical people based on the product's performance, uptime, and minimal crash/bug occurrence. "Hours worked" would be minimally relevant. One wonders if so many people would be so desperate to desecrate their production infrastructure if a high-quality work product and compensation were actually correlated.

But because we can't break out of the assembly-line 40-hours-per-week mentality, we pay developers as if they're line workers, and there's always got to be something on the line to keep those worker bees buzzing, regardless of the aggregate negative impact of constant uncoordinated meddling in complex systems.

This reminds me of /ꜧ/ which is used as a hypothetical phoneme that sounds [h] at the beginning of a syllable and [ŋ] (as in "ing") at the end of one. Since a given context can only ever have either [h] or [ŋ], there are interesting philosophy of science questions over why we shouldn't analyze it as /ꜧ/. (Though I don't think anyone actually thinks /ꜧ/ is right.)
Maybe you should stop thinking Ubuntu is Linux and actually try different window managers. I’m of the opinion that Ubuntu sucks, but that doesn’t really impeach the stability of Linux.

Though, if you want to get into it, Linux does actually suck. Really the only thing good about it is the software/hardware compatibility and the performance. OpenBSD is such a nicer system, it’s not even funny. Unfortunately, most users won’t find it practical as a non-server OS.
