Here in Germany I tested twice. Once, I took one of several online providers who send you a test kit - I think it was some 20 Euros or something similar - and you follow the procedure they give you and send the test kit back. You get an email and a website with the result after a few days. This is just for your own information, you cannot use such results in court, for example.

Another time I asked my local city water lab. They had no procedure for some random guy from the public, since those other companies exist and already make it convenient, but they still did not even try to send me away and the big lab boss himself handled my case, explaining the procedure and all, and taking the water samples back from me. Price was similarly little.

By the way, that second time I tested a very commonly sold entry-level Italian portafilter machine, a Rancilio Silvia with a brass boiler that even today contains lead. Following the sampling procedure I had agreed upon with the lab boss as the correct one the lead values I got back significantly exceeded the limits. And about those limits, the medical limit is zero. That the official limit is higher is because our society is unable to get us to that desirable level.

.

By the way, a good chelator for lead is DMSA, which is produced very cheaply in China. Russians produce "Unithiol" (DMPS) which is best against mercury, and somewhat good against lead (and a lot of other stuff). I actually got Russian Unithiol even though DMPS also is produced here in Germany as "Dimaval". I never used EDTA derivatives for chelation, but I have many years of.. experience with DMSA and DMPS. See somewhere in my comment history. That is why I took lead a bit more seriously and why I tested my portafilter machines. I now have an Ascaso Steel Uno PID whhere the manufacturer took great care to eliminate anything that could be problematic in all components - plus, it's a really good portafilter machine :)
There's plenty of material on those topics already. In fact, another big book about graphics was discussed on HN yesterday.

The areas where we need new books relate to multi-user games and scaling. How do you build a really big world? How do you manage terabytes, or even petabytes, of remotely stored content? How do you deal with client/server lag? How do you deal with content loading during fast motion? How do you do automated level of detail generation and impostoring? In worlds with user-generated content, how do you do quality control? How do you deal with overload due to excessively detailed content? How do you make a modern layered clothing system? How do you deal with too many players in the same area?
If parents could turn their children into tech company CEOs, how could we get non-borderline-autistic weirdos? That's the real question lol. But honestly, I'd expect that the actual result would be that severe autism which results in disability could largely be selected out, but neurodivergency would mostly fade into the background of the data. It's still around for a reason, and I personally am thankful even if I do have trouble with eye contact. If my sensory sensitivities were significantly worse though, or I had co-morbid epilepsy, I might want a tweak or two.
If you are worried about space i recommend that you look at the surface area of earth and the volume of space that’s accessible to us underneath the surface.

1) So news dropped today which was a big red day across the board to begin with. So if we want to quantify let's ballpark the ESG drop news in a -1B marketcap? I remind you Tesla is (amazingly) a 750B company. If they think that a -1B on hugely red day can make it harder for them to raise capital, then they are better off closing shop on all their Gigafactories because evidently there is no point in continuing the enterprise

2) Yes, it's exactly like that, punishing those who burn oil hurts those who mine oil, if it doesn't it only means that those who burn oil found a way to hide from ESG rating by becoming a private company and getting financed elsewhere eg. via private equity or using old fashioned bank loans and credit lines, or even by convincing clients to pay in advance or with less delay.

Actions and desires have consequences, the passion that people have for climate change has consequences, when you wanna get to zero you don't get to skip anything and even companies which people are emotionally attached to (such as Tesla) have to comply.
That’s maybe revenue for 20-30 engineers at a moderate (though less than 100) %age of Silicon Valley salary. While they aren’t having to do the full render engine work I don’t think it’s going to be a purely nominal amount of work.
Indeed comparing with CPython, which the link is about.

Indeed CPython is not JIT and PyPy is, but CPython is unfortunately usually what you get, comparing with PyPy would not be fairer since the goal is to speed up "vanilla" CPython.

It's unfortunate to me that the default python interpreter, so widely used for scientific computational purposes, is so much slower than the JS interpreter you get in your web browser, and then we're being happy +24% benchmark results about this when 30x faster is known to be possible (e.g. with JIT).
I'm "old" (~50) and I don't take it as age related. It just sounds like you are at a point in your life where you have different priorities and should look for jobs that match those.
This is for an enzyme, not bacteria, but to answer your question bacteria still need water, so if you keep the plastic dry it should be fine even in such a world.

PET soda bottles will be sterilized, then sealed. The outside is dry and won't decompose. You won't be able to re-close it and leave it out though.

For things that need to stay wet, like drain pipes, you would add chlorine and use PVC which is unlikely to be edible to bacteria.
Yeah, good point. Theoretically, a more optimized enzyme might be able to do it at ambient temperatures, which they mention in the article as a target. Assuming the search space for enzyme mutations isn't already exhausted.
That sounds like the former, to be honest. What I meant was, is there a black market of the big wheels of fake parmesan, with forged serial numbers, claiming to be approved by whatever body controls the name Parmigiano Reggiano. A plastic bag of grated cheese that says "100% grated parmesan" feels like it's not trying to claim to be real Parmigiano Reggiano. I can see why a Consortium would want to impose a strict definition in order to protect their product.
You can directly with gstreamer, but it's a bit of a hassle to set up. You could try this python convenience library: https://git.aweirdimagination.net/perelman/minimal-webrtc-gs...
I’d be careful with this. You dont want to build a reputation of building buggy software and have sloppy work.

That's a much smaller threat than if the organism itself were to be applied directly to plastics.

Designer organisms aren't generally well-suited to spreading in the wild and even if they were, they could be engineered to require a certain dependency that they would die without. But yes, still theoretically it's possible.
The vast majority of the mathematics required to really understand ML is just probability, calculus and basic linear algebra.
If you know these already and still struggle it's because the notation is often terse and assumes a specific context. Regarding this the only answer is to keep reading key papers and work through the math, ideally in code as well.

For most current gen deep learning there's not even that much math, it's mostly a growing library of what are basically engineering tricks. For example an LSTM is almost exclusively very basic linear algebra with some calculus used to optimize it. But by it's nature the calculus can't be done by hand and the actual implementation of all that basic linear algebra is tricky and takes practice.

You'll learn more by implementing things from scratch based on the math than you will trying to read through all the background material hoping that one day it will all make sense. It only ever makes sense when implementing and by continuous reading/practice.
No, they produce water and CO2. Nothing toxic, unless you don't give enough air (so obviously make sure to give enough air).

This isn't some theory - right now, today, lost of plastic is being burned, and it works just fine. They try to keep is off the radar because of misinformed people thinking it's bad.
What would cause them to be an environmental issue? As far as I know they can be built in a safe manner and there is plenty of space for them.
At Brex we tried to speed up the typecheck speed in CI by saving and reusing the build output from the incremental cache.

It worked pretty well for the most part, and I would recommend looking into this for most teams since it's a pretty quick win. Most typecheck steps went from minutes to low-double-digit seconds (admittedly still slower than I would have hoped).

But occasionally there would be gigantic spikes back to minutes for seemingly small changes that seem like they should have been incrementally check-able. I suspect these might have something to do with circular dependency chains, but didn't have bandwidth to dig deeper.

I wish TypeScript's incremental checking mechanism and file formats was a bit better documented and less opaque, so people could better reason about and optimize typechecking performance, and possibly build support into other systems to perform & share some of the analysis they're already doing to avoid wasted work. That and to make it less of a giant blob for the entire codebase, and more of a set of files that are incrementally and individually update-able for better cache granularity and faster updates.
Argo, flux, fleet, gitlab pull based…. Does anyone have recommendations for a good comparison blog post?
This is something that makes more sense as a business ran out of your garage than as an investment opportunity. Someone hand-pruning stack overflow search results wouldn't need much to keep the lights on and could just sign up a certain number of clients.

"Boutique" to me means high end tradespeople focusing on a specific point of view over growth. I can't imagine a search service fitting that category and allowing advertisements. That's not what either party involved is there for.
Eating large chunks of Parmigiano-Reggiano off of a large wheel is AMAZING.
Hence the "So it's something that had be delayed.", and not "this is something impossible".

Javascript has the benefit of having billions of dollars allocated to it from Google/Microsoft/Apple to hire dozen of amazing engineers full time over decades to work on it.

Python has existed since 1994, yet in 2011, the Python Software Fundation budget was less than $40K: https://pyfound.blogspot.com/2012/01/psf-grants-over-37000-t...

We are talking a difference of funding of 6 order of magnitudes. Not to mention one is a language that has to stand on its own, the second has an accidental monopoly on the most popular plateform in the world.

So it had to be delayed, unlike for JS.

My point is that the courts are going to have a hard time with this.

We use plastic in many places with the idea that it’ll never rot.

Obviously we want plastic to eventually biodegrade, but I wonder what sorts of chaos would be caused by it.
Wouldn't this be extremely dangerous if a form of "plastic rot" was created? Things like PVC sewer pipes, or any long-lived plastic parts in cars/equipment could now degrade over time, which could create huge costs to find alternative materials. After all plastic is pretty useful because it is biologically and chemically inert.

The ones they put in here are between 40-60cm wide for reasons I can't fathom.
"Proprietary" was bad wording, technically other people can use etcd... I mean to say inflexible & incompatible. Someone suggested supporting Consul 8 years ago (nearly functionally equivalent to Etcd), was requested for years by like a thousand people, never happened. Somebody even submitted a PR I think, but it was quashed. I/O should have been abstracted at the very beginning as loosely-coupled pluggable layers.

> If yes then that would mean that anybody that deals with "Parmigiano Reggiano"-based-products would have to request some kind of access (userid&pwd, or some ssl-certificate, etc...) and submit transactions (basically like a mini-bank only for this specific type of cheese)?

They need a fancy scanner and the right software to verify these embedded trackers anyway. Just sell scanners configured to verify the cheese to anybody that cares to verify their cheese.
Youre right in all of those. Except, we don't want the product of another successful project management and software development. We want to move forward.

Current games also take 10^10 as long to create compared to the games of 1970s. The effort was put into making these games. They materialized. The next generation of games wont materialize without someone putting in the effort and the money.
Hi!
I co-led the billing stack re-write at Uber circa 2017 and it was an absolute nightmare.
Some of the unexpected hard things that are not mentioned in this article:
- Manage promotion was very complex
- Modeling money (we used to model it as cents ie 1/100 of the common denomination ... turns out it broke a lot of countries like Japan where the Japanese Yen doesn't have cents)
- Timezone is a hellhole

One interesting open source project was https://killbill.io/

One of the particularly amusing things I’ve noticed in right wing agitprop things like this is how badly they are at imitating actual leftist discourse. Nobody talks like that IRL except in the minds of RWNJs. I can’t think of a single left leaning space I’ve been a part of in the past five years where someone would say that and it wouldn’t go unchallenged or people would look at them very weirdly. It’s such a fundamental misunderstanding of the underlying dynamics.

It’s one of the most obvious tells, I’m just surprised that they are still this bad at it after so many years.

In their defence it doesn’t matter in practice, the target audience simply does not care or know the difference.
Well I hope there's a way to remove those trackers, I always put the rinds in soups and stuff so it would piss me off a lot to learn there's some non-food related stuff in it.
I might be wrong about the exact historical reason.

But the way I see it "spectral decomposition of A" is a way to express A as a sum of orthogonal, rank-1, operators. A = \sum l_i u_i u_i^T. Those l_i are the eigenvalues; u_i are the eigenvectors.

The eigenvectors look a whole lot like the "modes" in a Fourier decomposition. And if you plot (i, l_i), the eigenvalues are a bit like the "spectrum" (the amplitude of each mode).

In fact, the complex exponentials (the modes in the Fourier decomposition) are also eigenvectors of a specific operator (the Laplacian).

Math people are good at finding connections between things.
If 80% are good submissions it’s a useless filter and should be dropped.
Unfamiliar with WebExtensions API, but is there no polyfill type tool for the v2/v3 API, which can be specified at "build" time?
This is an interesting paper by the Brave search team:

Essentially “goggles” allow anyone to create their own algorithm and share it. It’s a really interesting concept. Definitely worth reading the paper.
I know you had several points in this comment but this stuck out to me

> Then more DAs are choosing to prosecute fewer crimes and negotiating down serious crimes that would trigger alerts (usually felonies) to lesser crimes so the data that is there may not be representative of the situation.

Isn’t this representative of the situation? They didn’t get a felony and the background check shows they didn’t get a felony? Are background checks supposed to be extra punishment on top of what the judicial system determines?
Yes; would be silly to dictate people's font sizes and the like. Perhaps we can then agree that there are certain configs that do belong, and others that might be less wise to include [if your boss dictates that you use Arial 10pt, get another job!]

I don't think you need to worry about choosing one path over the other. If you want to do "non-boring" things, you can still do them while working for a more conservative/mundane company. The latter can provide a solid foundation for you to explore the former.

When I was in college I was pretty entrepreneurial. Since graduating and starting my career over the past few years, I've built a good foundation for myself (getting my own place, saving money, and growing in my career in a way that's complementary to my personal interests), and I'm now ramping back up to the levels of thinking and dreaming that I used to do (if not moreso).

Edit: relating to your mention of the importance of relationships, note that you need to make connections with people that do the things you're interested in and keep your mind oriented towards that. I have entrepreneurial and creative friends. You have your mentor. You might benefit from meeting people that are closer to you in terms of how far along they are on the path towards what you're interested in - people to grow with and mutually inspire and encourage.
So many tech companies are bloating the interview process with seven or more interviews. For my current role I did several interviews and the record during my most recent cycle was ten IIRC. The particularly annoying part is that most of the time the rounds are almost complete duplicates of each other just with a different person.

edit: I just checked my calendar and I had nine meetings/interviews with Cruise before they rejected me.

The Fed's $2.7T mortgage problem
Every node in the cluster "knows" the network address of the Leader. It knows because a) it's part of the Raft cluster configuration, and b) every follower "heartbeats" to the Leader periodically.

So it's actually pretty simple for a given node to contact the Leader. If a node receives a request which must be performed on the Leader, and that node is not itself the Leader, it can do one of the following things:

1) reject the request with an error, but this isn't really a production-viable option.

2) reject the request with an error, but tell the client where the Leader can be found, so the client can retry the request, this time sending the request to the Leader.

3) transparently forward the request to the leader, wait for the Leader to execute the request, get the response, and return the response to the client. In this case the client doesn't even know the forwarding to the Leader happened.

rqlite supports mode 2 and 3, client can choose which behavior it wants, on a request-by-request basis. Option 3 is the default.

Hey thanks for showing me this. What lies beyond the starter plan in concrete terms?
The explanation isn't great, but the reasoning is that people will already have their IDE running TypeScript + type checking running on commit, so adding that onto the process just slows it down without much real gain.

(This is of course assuming that most type errors are largely localized enough that your IDE will find them).

I'm sure I got fucked this year: one of those sites said in big letters at the top "we attribute all transactions until midnight to today," so I chose them.

I gave them thousands of dollars (hoping to get some of it back as credit card points). I immediately got an email saying "Thanks for your payment at 1:30 AM (not my timezone, tomorrow)." I was livid, and I had no recourse.

I don't even know how to check for the fine and pay it. I'm just waiting for an IRS nastygram at this point, so I can contest their "processing fee" on my credit card.
In general, the rind is put into food and removed before eating. Kind of like you are making the liquid into a sort of cheese tea... or the way you would season something with a sprig of rosemary, a cinnamon stick, or other spices that you remove before eating.
