> The crown vic police interceptor (which is likely what the op is talking about) is a fairly "modern" vehicle

Yes, it is.

> I'm not sure when they stopped making them, but it had to be sometime in the early-2000s, maybe a bit later.

The CVPI (Crown Victoria Police Interceptor) and the Crown Victoria itself were retired in 2011. Their immediate replacement from Ford was a Taurus based Interceptor sedan and SUV. Most officers I know derided the new Interceptor platform for having less acceleration and smaller interior space than the old CV platform. Where I live, the Dodge Charger police vehicle became much more popular after the CVPI was retired.

> The one potential issue with a crown vic that would make it more dangerous that other cars is that it had a saddle fuel tank. Ford did not learn the lesson of their Pinto. Rear-end accidents with a crown vic had the potential to turn in to fiery death-traps. It wasn't until a police detective here in Phoenix got horribly injured (but survived) did they make modifications to police fleet vehicles (I think they put in a racing fuel bladder or something like that in the tanks). I don't believe such modifications were implemented for standard civilian crown vics...

This is correct. The last revision of the CVPI (2004 to 2011) had a ton of safety improvements, including to the gas tank.

> Regardless, the crown vic isn't the same as much older vehicles. While it likely isn't up to modern crash standards, it is still a fairly new vehicle that does have crumple zones and such, and won't spear someone thru the heart with the steering column in a front-end collision.

It's still one of the safer (for the driver) cars on the road today, though its weight and bulk make it more likely to cause the most damage to other vehicles in any accident it's involved in. And you're exactly right about the steering column, it's a breakaway design. I know this because I've had to replace a dash component that required unbolting the steering wheel and column.

It's an interesting study. One thing I'm not sure about is: were the participants in (any kind of) pain originally? Was it chronic, or acute?

Intuitively, and from my experience of 15 years of fighting with chronic pain, it's incredibly hard to emphasize with anything at all when you're in serious pain. It's hard to even think about anything other than pain. I'd say - again, from the perspective of a chronic pain patient - that reducing the pain with medication makes it possible to have empathy towards others. Obviously, I have no neurochemical data to back this up, I'm just saying how it looks like to me, psychologically.

If I had to guess, I'd say that being in pain does little good for empathy and it's a memory of being in pain that counts. When I'm in pain I'm not going to care too much about yours, but when I was in pain, and I remember it clearly, I'm going to care a lot.
As a keyboard jockey, you’re liable to get RSI, as I did — as such, I’ve been using a fountain pen for nearly 20 years. You use much less pressure when writing, and it’s great using a pen that you don’t have to throw away.

My two Lamy 2000’s have been going strong for many years. But even a cheap Lamy Safari can last just as long.

If you’ve never tried a fountain pen, strongly suggest you do.
I use Monodraw[1] on my Mac, I really like it because it's ascii rather than image or vector based which makes including the diagrams in markdown really easy.

> Most of the residential developments in the last half century has been what are called 'urbanisations'

Any data to back this up? I've checked eurostats [1] and the numbers don't support this assertion: 66% of all dwellings are flats (there are no flats in spanish urbanisations), and only 12% are detached houses (the most common building type in urbanisations).

Also, notice that these numbers are the larger (for % of people living in flats) and smaller (for % of detached houses) in all of Europe!

> I'm guessing companies assumed he'd leave in 3-5 years and didn't want to invest the time.

3-5 years is a pretty long stretch in this industry. The longest I’ve ever held a job is just barely 5 years. Most tech employers— at least the smart ones— know the average bounce rate in the industry is high. Older employees tend to value stability, for various reasons. So I don’t buy your argument.

If there’s a reluctance to hire older devs, I suspect it’s because they have higher salaries and maybe because they are (inaccurately) perceived as being unlikely to know or want to learn new tech.

I've been looking for something like this for quite some time. I was hoping Cloudflare will offer it but they haven't

My main questions are
How do we know if we can trust them with our data?
How fast are they compared to Cloudflare ?

I wish there was something like Signal but for DNS. Similar in the way that you don't have to trust them to know they are not doing nefarious things with your dns queries.

That’s decidedly not my experience. I’ve certainly been presented with bills for every single thing I’ve done at a hospital, including visits that I was assured I would not be billed for. I’ve even spent months trying to work out arrangements with hospitals and insurance only to have my bills sent to collections. The thousands of people who file bankruptcy each year for medical bills would likely wonder what you mean, too.

Where gerdesj says "Miguel's method", xe is talking about the init and rc system written by Miquel van Smoorenberg (originally for Minix and later ported to Linux) that copied some, but far from all, of AT&T System 5 init, rc, and adjuncts.

gerdesj is specifically referring to the well-known problem that the helper utilities and functions for rc scripts varied wildly from operating system to operating system.

It's worth noting that the Debian people introduced another set of conventions recently, in 2014, with rc scripts in the Debian variant of the van Smoorenburg system now interpreted by a /lib/init/init-d-script command instead of a shell.

Acetaminophen/paracetamol is really only toxic in higher doses due to its metabolism, as only the intermediate metabolite NAPQI is toxic, but that cannot build up in low doses.
Well it's anecdotal but when we have tried something similar (Buy on our website and use the app as a 'dumb client') on a couple of different apps they refused to accept it.
What's funny is that many young people in the industry now would never think of staying at one place for 3-5 years cause they don't want to invest the time.

A neighbor of mine is in his 60s and lost his job the same way. He can run rings around anyone I know but he can't find a job or even get an interview.

> 2. I'm not so sure that smart people should be coding.

It depends on their attitude. The smarter the better, IMO, as long as they understand that the code they're writing isn't for them. They can go hack on some personal project if they want to flex their "I'm so clever" muscles, but if they're writing commercial code, that code is for the dumbest of the dumb who will ever have to maintain it. If someone can focus their intellect towards making their code clear and simple then great.

Of course, as you say, someone who's competent but has a slightly humbler intellect will just automatically write simpler code.

That's distressingly vague, especially when he provides screenshots of the recent termination emails. If there wasn't more to this, you'd expect the history of that other account, which is pretty clearly relevant here, to be laid out in a lot more detail.

I agree that Google is prone to arbitrary and Kafkaesque behavior, but this instance smells fishy.

> Wind, tiny earthquakes or even birds walking along the roof displace the tiles ever so slightly and they loose contact. Once the circuit is broken it is difficult to find and fix the fault. Even worse a short circuit can lead to heating and fire danger. Turns out regular solar panels are way easier and cheaper to work with.

How can you say this much about an unreleased product to which you have zero insight on technical details? This is even more bs than if the tiles never come to market...

Also, you can’t call a machine-bored tunnel a “tube” and expect to be taken seriously. Questioning lofty, sci-fi-is goals? Fine and reasonable. Gaslighting actual, tangible products? Sounds shady.
That's hilarious. Knowing how to us vi(m) is a valuable skill (and one I lack sadly) but you only really neeeeeeed to know if if your IT role involves working on random remote systems.

As a software developer that has never been an issue for me. I can think of only one or two times in my whole life I was working on some random server and didn't have pico/nano available. And even then I think I was just able to use sftp to edit it with my local editor of choice.
The neighbor I mention in my other post told me he'd work for $30K if they offered insurance and he'd stay for at least five years. As a software engineer, I know he can run code rings around anyone.
Even better: use iTerm's tmux integration!

In my current workflow, I ssh into a server and then run "tmux -CCu attach -t main", which will open all the windows and tabs that I had open previously, but as regular iTerm windows and tabs. It's possible to also maintain tab/window colors and such, but I found all that to be a bit fiddly.
Lots of people (e.g. [0], [1], [2]) have blogged the Feynman technique, which seems to have been first documented in Gleick’s biography [3]. The various descriptions identify the following four steps:

* write down the name of a concept

* write down an explanation of the concept in plain English, identifying the bits you don’t know

* review the explanation, going back to source material if there is something that you haven’t yet explained, and repeat step 2

* simplify the language and rewrite bits where you have paraphrased the source material

A small, concise explanation IMO can be: software is an implementation/modelisation of an idea. So not a product.

You may pay someone for his/shes expertise and time and resources, but you can't pay him/her as you pay a car, a cheese, a house.

Since things change and need regular maintenance so consultancy/time it's not exactly a oneshot thing many try to sell the idea of software as a product before and as a service after.

Those people are really scared and disturbed by the idea of culture, knowledge and free communication because that means in the first place demolish 90% of them, and secondly reduce the remaining 10% from "human-gods" to mere "workers/expert" for hire.

Since our society do not really learn nor remember things well they cyclically find new/old way to keep their model up. In the past with mere ignorance and marketing, after with lock-in, after with total lock-in (cloud/* as a services) even after with controlling production by mere scale diversity (they became too big to have real newcomers that may undermine their throne) and private knowledge (thanks to continuous schools reforms and careful media push).

Sometime they arrive to a point society explode so they have to back up, they loose something but quickly recover. That's the cycle.

I don't think developers would be eligible for bounties for vulnerabilities found in their own projects.
For example, I find that technical interviews for experienced developers tend to be harder, which makes me infer an "up or out" culture. A dev with 20 years of experience isn't even evaluated for normal individual contributor roles, instead they are chief code wizard or unqualified.

Younger devs, especially college hires, are given more leeway to train on the job and grow into their level of aptitude and interest. A similarly intelligent and driven middle aged dev won't be offered the same chances.

The final decision to terminate is usually taken by a human, not an algorithm. However, that human is not allowed to speak to you because anything they say is a potential liability in court or in PR terms.

Companies exist to produce profits for their owners. Without public regulation, you should not expect fair and faithful service. If you no longer represent a revenue opportunity - since they clearly decided just that - then you no longer exist.

The solution is often to try to align the incentives of the company with your own, with public shaming campaigns like this one.
I looked for studies supporting your statement. The evidence is conflicting, and there appears to be no conclusive evidence one way or the other, although some people certainly are fond of repeating this as if it's fact.
Shouldn't be up to the app store owners to provide evidence against an app and then remove it? Where is the transparency here? These are huge corps. They can well afford to at the very least state why they're blocking a certain app, not just to the dev themselves, but to the public as well. There's a power imbalance here and the onus is on Google/Apple/etc to do the right thing, the way I see it.

Most police forces use VLC to view CCTV recordings and other multimedia evidence. It's an entirely logical choice of software, but it presents an obvious risk in the current climate. I would imagine that many intelligence services use VLC for similar purposes.

A nation-state adversary with a VLC RCE 0day could do some serious damage; if they also have an 0day for a popular model of CCTV DVR, they've got the keys to the kingdom. Those DVRs will never get patched and a nation-state adversary could dream up all sorts of ways to induce a police officer or an intelligence agent to play a media file, but at least we can harden VLC.

In short, the two fields just look similar, but are actually extremely different fields.

Physical simulations need to preserve entropy, maximum principle, energy conservation and other kinds of conservation, preservation of consistent states, convergence in case of finer mesh.

There are multiple equations which model different forms of fluid:
1. Incompressible Euler (For liquid)
2. Compressible Euler (For non-viscous gases)
3. Navier Stokes Equations (For viscous liquids)

There are multiple solver methods:
1. Finite Difference
2. Finite Element
3. Discontiguous Galerkin Finite Element
4. Finite Volume Method

There are multiple equation methods:
1. equation splitting is just one of the many methods possible.

Just because the equation is unique does not mean that the solution is unique. Single equation provably have multiple and even infinite solution for the same initial condition. Computer graphics fluid simulation does not care (with a good reason) about this and hence, often their simulations even though they look kind of nice, are often incorrect since they do not demonstrate various physical characteristics that must be preserved.

In contrast, the qualitative/quantitative constraint in physical simulations are very strict. You need to know a lot of theoretical math to even understand if you are even computing the correct solution.
