Germany's biggest Craigslist-like service recently added a service like this for purchases that are shipped. I sold my previous MacBook using the system and found it really stressful to wait for the buyer to confirm the item. In my case, it was just someone who was a little bit slow and just forgot, but I can imagine abuse in the system. Same thing happens with PayPal buyer's protection.

I can't think of a better system though, to be honest.

> Charging a 70kwh car battery would require a 4.2 MW charging cable/site

Think of it this way: no passenger car EV today can make full use of a 350 kW CCS charger. If this battery can enable a flat charging curve at 350 kW, then it would only take 17 minutes to charge a 100 kWh battery from 0 to 100% state of charge.
I really enjoyed this article. It reflects my experience.

I used to have a teacher that would say “Any day I don’t learn anything new, is a day that I died.”

I’ve always been good at picking up new stuff, and understanding difficult concepts, but these days, I have made a conscious decision to do one thing, and do it as well as possible. I’m probably at 90%. I’m fully aware that I’ll never be 100%.

That makes it fun. I like challenges.
Angry posts about UX like this one are something making the Apple ecosystem uniquely worth it to me. These are often influential people pointing loudly at fairly obvious (or non-obvious) issues and Apple (kind of) have to respond.

Meanwhile Android (and other) products are so fragmented and people are so used to things not working that nothing will ever change.

More people should be angrier about bad UX to make companies start to care. Fix your damn glaring issues. Test your stuff. I am aware that this is hindered by people primarily looking for cheap- instead of reliable products.
I'm considering making the next move in my career, can you expand on the top firms and by full name so I can find them?

Much appreciated :)
Could there be a valid reason for this ?

For example: A trend may be appearing where hackers gain control of the GPUs of unsuspecting users and then mine crypto in the background. The GPU uses more power and slows down given the user a bad experience. Nvidia wants to decrease the value of such hacks and decided to cripple the hardware.

Similarly reducing the incentive for employees to mine with company equipment and electricity.

> I feel like this article is pointing a gun at the wrong faces. These companies are most likely doing this as a form of social giving.

No, they're doing it because they know they can severely underpay these workers and treat them badly, knowing that they have no recourse to push back.

People who run such businesses rarely have any pure motive. It's all about the profit and they don't care who suffers in the pursuit of it.

Now if they'd provided the prisoners with a decent wage for their work, that would be a different matter, and indicative of some good intent. But none of these companies are going to do that, when they know they have a source of people they can continually exploit.

"As a market practitioner of many decades" -- I like that phrase.

In the first phase, it was purely retail speculation.
However, we are now entering into a new phase. ETFs are being issued. This makes it easier for institutional money to buy. Also scary. I'm not concerned about "fast money" (hedge funds), but rather "slow money" like pension funds.

Final phase: I notice that investment banks are slowly beginning to open cryptocurrency trading desks. They may trade directly, but mostly they are interested in derivatives. That is my biggest fear. How is that any different than CDS on MBS/ABS/CDO? (Credit default swap on sub-prime mortgage bonds) In short: The underlying was junk loans. Derivs on crypto feels like the same wolf, but in a different skin!

This is a big one (for me at least). A downside of being more knowledgeable on a lot of topics than the people around you is that you can develop a certain hubris that's not good for learning. Learning something new you absolutely suck at is a great way to regain some humility. And having some humility is absolutely needed when you want to be teachable.

These matters are quite complicated and very tough to handle with means tests, or piles of one-time cash. Instead we need to acknowledge that the US has created a worsening class of the generationally impoverished. Bear in mind that the federally defined poverty line is deeply flawed, and people living such lives are often severely impoverished.

Then we can have a conversation about benefits cliffs, which actively discourage people from even trying to better themselves by withdrawing benefits faster than people can improve their lives and forcing people to dismantle their lives before they even qualify for aid.

I have not been tested on the fundamentals of programming taking interviews from FAAGM and other famous tech companies. Instead I've been asked "puzzle" questions that generally have nothing to do with the millions of lines of code I've written in the past nor anything to do with what I will do for the company. All those questions on leetcode are 95% unrelated to actual problems IMO.

95% of every web app, mobile app, or native app is just very basic stuff. How often do you need to be able reverse the first half of signally linked list? Or compute the most amount of water that will fill a vertical grid. Or find the largest rectangle in a bitmap. Or divide to giant integers. Or solve sudoku puzzles?

The interview should not be "can you solve a puzzle that took 50yrs of programming before someone noticed the solution". It should be "will you be productive on our team". I don't feel most tech interviews actually check for that. In fact I know several people who got through the interviews at the last company I was at (one of the top 4 tech companies) that were not productive at all. Sure they could answer the leetcode type puzzles but they couldn't actually get work done. Many of them were eventually let go when enough colleagues reviewed them poorly.

The article claims these interview questions test for fundamentals and I agree that fundamentals are important. I just don't agree the leetcode style questions asked test for that.
"Believing we're the only intelligent life in the universe is an epic violation of the Copernican Principle."

Not necessarily, because the principle collides with observer bias in this case. I don't think it's valid in this context.

"There are so many other explanations for Fermi Silence"

Of course. I'm not concerned about the explanations themselves though - more about the emotional dimension; the attachment to the underlying idea. Lots of people seem to yearn for the ETI to exist at all. They'd be fine with any of the explanations you mentioned to be true, as long as the core concept is protected.

"None of this requires aliens who will teach us anything, one way or the other."

My point is not that they would, or that it's a logical scenario. My point is that humans exhibit a strong cultural need for this type of narrative.

I'm interested in this anthropologically, so to speak. I don't really care about the actual aliens (or the lack thereof).
I have a personal theory about the great filter:

The great filter is evolution converging to a local maxima and not evolving creatures capable of higher intelligence.

We're scared about the mass extinctions on Planet Earth while at the same time they were the ones that cleared the field for different animals to evolve. Case in point, the Dinosaurs going bust paved the way for small mammals (then large mammals, etc)

"But couldn't we have intelligent dinosaurs" maybe not? (Because of a bunch of stuff that only came later like animal packs, family life, etc - though it might be argued that some dinosaurs had that)

Then we have the fact that mammals are born much more frail than other species and needs "a family" to take care of them for a while (and human's big heads made that "while" into "a lot of time")

But without that you don't get societies organizing. And the bigger the society the more you can do with it.

Every musician/singer that is famous, sounds unique—like themselves and no-one else.

I keep coming across, in many fields, people saying that their subject can be learnt but not taught. Botvinnik (founder of the Russian School of Chess) said it about chess! I think it's true of jazz. You have to learn it for yourself, by listening to what you love and selecting from it and emulating what you love.

Also a yubikey being able to hold 25 of those is kind of pathetic.

Used Kubevirt for a while in my homelab, for my netbsd/tribblix/omnios vms, but in the end decided to switch over to hashicorps nomad for that purpose.
Kubevirt was doing alright, but it always felt like it had too many bells and whistles. Networking was an issue too, at least for me.

In the end nomad took over and i had great experience, with it. Consul + Nomad is an amazing synergy. Everything just works, but you still have control over everything and your installation does not feel like a blackbox that just tells you to eat dirt sometimes. Deploying vm's with nomad&consul agents inside + and running zones [0] on vm's was not trivial (mostly networking issues again), but it was actually fun to do. Which i guess is the reason i stuck with nomad.

One thing that nomad is missing is better CSI implementation. They are getting better at it, but back then it was an issue. Documentation in general is not that great compared to k8s, gladly there is a gitter community that can is very active and dedicated. Still not having to mess with piles and piles of yaml feels great.

Currently i have downsized my homelab to a few droplets and am running mostly podman workloads, but i would recommend nomad to anyone who wants to have fun.

tldr: Kubevirt is a great product, but nomad does the same thing and is fun to work with.

Prisons don’t incarcerate people. If the money from sales go to prisons and inmates then there is no incentives for judges or prosecutors to incarcerate anyone. If money somehow are connected - this should probably be changed. The fact of selling products to the market is not a problem here.
> once i have access to the computer the keys are somewhat free to use

Once you have access and either root or pass whatever extra authentication the access requires.

> storing the key encrypted on a drive where its only accessible using a passphrase

The extra failure mode here is that someone can copy the key and crack your password offline on their own time.

> using something that was touched and left a mark and some glue.

At that point a camera catching your password should also be a potential threat. But yeah, if that's something you're realistically worried about then it's not a great solution for you.

Show HN: One Way Dungeon – A game I've been developing in the last five months
Five months ago, I quit my job and started making a game alone. One Way Dungeon was what came of it. And the accomplishment of a life goal.

I'll continue supporting the game and adding new content to it. But not at full time. I'm going back to a "normal life".

(For those who don't want to install it or don't have Android, you can play it here: https://vaskivodev.gitlab.io/onewaydungeon/builds/release-1-...)

I welcome all and any criticism. And I hope you like it.
Thank you!
The point was plateauing, not that what you make doesn't taste great to you. Making stuff that tastes great to an average person isn't hard, you'll reach there really quickly, it is improving after that point that is hard.
Intel 11th Generation Core Tiger Lake-H Performance Review:Fast and Power Hungry
Since I started interviewing applicants, my two favourite questions are:

a) What's the difference between an array and a set?

b) Describe how a hash table works.

The reasons are:

a) It is important to know the difference between ordered and unordered collections and I don't want to be in a position where I don't trust that my teammate will use the right data structure in their PR.

b) a hash table works with the same principles on which scalable services are built: database sharding, traffic loadbalancing (with stickiness), kafka stream processing, etc.

In my experience, those two questions are a good indicators on how the interviewee will perform in the rest of the interview.

So what you’re telling us is that you don’t communicate well, or at all, with other people. Other people who will, later, have to maintain your code.
Just noticed how no one has mentioned how the criminalization of drug users creates thousands of free prison workers.
I can't understand how prisons can be private... it creates an incentive for them to lobby keeping drugs illegal. There are so many horror stories, like prisons saying that they'll close if they don't get some more prisoners.
> China is a dirty old dinosaur of an economy, it has double the carbon emissions of the US while only generating 2/3 of the GDP!

I think there's a distinction to be made between diseases that are infectious and those that are not. If you have cancer and you want to attend an event, that's nobody's business because they're not going to catch it from you. If however the disease you have is serious and highly-transmissible then that's another matter entirely.
Weird. I've been using it for months with non-issue. Another comment suggested that maybe it doesn't last on mobile?

Crypto-Trading System in Python with Flask
Hi All

I'm studying the bachelor in IT, and teaching myself some things.
I've seen that with the cryptos, there is a big volatility. So i thought i can use this volatility to make some profits.
That's the Reason i built https://prinillus.ch

It's a crypto-Trading system that uses the api from pro.coinbase.com.
So you must open an account on pro.coinbase.com, open an api, and give the api-details to prinillus.

if you opened an account and gave in the api-details, the system can make trades for you.
It's a non-profit-System for me, as you can disable transfer in your api-permissions.
So my System is here just for you.

It works by different strategies, which you can see on the system itself. It also works with thresholds, so it nevers sells while not making any profit.
You can set a currency with a strategy, and let the system trade for you. It will use your Euro-Wallet to buy and sell. All Prices are in Euro.

As by now, im setting up an own mail-server, for info-mails and such stuff. (to mail with own domain)

The Code itself is on a private github (of course without the database).

Anyone interested in helping to improve or collaborate?
Is there anyone willing to invest?

Let me know under prinillus@gmail.com
checks price 40.3k...yeah it really plummeted. Everyone who upvoted this is a FUDster
In reality most mining happen with under-clocked GPU cores (and admittedly overclocked VRAM), and at very stable temperatures. The GPU that is used 24/7 for mining will be far less stressed than a GPU that is powered on and off, and cycles through a lot of thermal changes throughout the day
I made my own, but it only works for me heh. I know myself really well, I know what I need, so it's a somewhat simple task. Creating an actually useful one that anyone can install and use seems much, much harder.

I like Google's TTS and it was incredibly annoying to integrate with my bot. I realize they don't want you using it for free for your own purposes, but damn.

The choice for the prisoners is making $4.50 a day or sitting in their cell doing nothing to improve their life. Don’t act like this isn’t still exploitive to the point of it obviously being a false sense of choice —- especially with the BS that America will lock people up for. If a 14 year old kid in Alabama gets caught with a joint isn’t it convenient that the corporations in the state suddenly have access to a fresh new indentured servant — quite a nice replacement for slavery you guys have worked out for yourselves. If you want to see how civilized countries rehabilitate people see how prisons in Norway are run.

>Overdoses aren’t contagious.

But they do tend to cluster. Many people overdose because their supply is unusually strong, or they're clean and use what they would've taken at their previous tolerance. Knowing this we can expect more overdoses to happen in black markets, and the recently released (from rehab, prison, hospital, etc).
Yes, your USB key needs to have resident key support. I'm looking forward to the Solo key (which is now one or two years delayed from when it was originally supposed to come out), which will apparently support thousands of resident keys.

You don't need so many for SSH, but it's great for usernameless/passwordless auth with websites.
It's very apt. The only issue I take is the point to work on something important rather than something interesting. Sure, you can find interest at sufficient depth in nearly any topic if you're a good scientist, but you'll miss out on the truly groundbreaking stuff--the long tail stuff.

For example (obvs YMWV), when I started graduate school in the mid-aughts, my interest was piqued by a little studied RNA modification called pseudouridine. I actually had another prof in the department ask why I didn't want to work on something "important". Turns out it was pretty important for improving human health and reducing disease in unforeseen ways. If I hadn't followed my gut interest that said "hmm?" when I first learned about it, I would have missed out on something grand.

Maybe what I would add is the pursuit of a PhD, IMHO, is a privilege. It's a time to drift and wander around a topic of interest; not a time to bust your ass. It's a time for pious interrogation of the universe. You should not be gunning for money or fame or success, but rather focused on making connections with other scientists to come up with answers to interesting questions about how things work.

So who can spend so many of their prime years possibly not accomplishing anything of value? Someone who is privileged. I am all, all, all for opening up doors to everyone, but the risk is that "getting a PhD" turns into the pursuit in and of itself. We are seeing this now more with people assuming the higher degree is simply the next step after a masters or bachelors degree. It wasn't designed for that.

But with all this being said, I love how humanity evolves and I'm down for enabling anyone who hustles to get ahead. If this is what society thinks a PhD should become, then let's try it out. But people need to make sure they realize the way things used to play out after the degree are no longer the rule but more of the exception.
