Carbon zero would probably mean not putting any new carbon into the cycle. Not all carbon emissions are positive contributions to net carbon, if they’re just reusing carbon that was already being cycled through.

Consider as a thought experiment a world where we suddenly have limitless but “clean” power (ie. fusion comes sooner and better than even the most optimistic expectations) and we start doing carbon capture that also produces burnable hydrocarbons as a byproduct. Running an ICE off that fuel doesn’t put any new carbon into the air, it just recycles what was already there. Obviously this isn’t likely, but it illustrates the premise in an exaggerated way.

More practically, in theory wood from farmed, new growth trees fits this mold, but in practice it’s not a terribly efficient or clean fuel once you take all the externalities out. And obviously you’re not gonna power a car on it.

But fundamentally, the main thing we need to do to get to zero is stop breaking the planet’s own sequestration of all the carbon that was in the atmosphere before it was hospitable to modern life. At this point doing that is very much a political problem, we probably have the tech to replace the energy we’d lose from that, we just aren’t willing to build it out fast enough.
I don’t think you’re “bumping against the same “free” forces somehow”, because you seem to have given away the whole pizza for free for 6 months.

I think you need to study companies that transitioned from a free to a paid product rather than compare yourself against businesses that increase their regular sales through free samples.
Agree. While it's great that the engineering manager understands engineering compensation and the nuances between different models, it's the HR departments that need to be educated on engineering compensation.
Especially in organizations that include a high share of non-technical workers, the divide between engineering vs. non-engineering will be huge. Even standard benchmarking models compare companies based on the city & commute time instead of a whole region, country, continent.
Another happy propranolol user!
Both fat and glugose have more than order of magnitude better energy density (both MJ/kg and MJ/litre).

Human metabolic efficiency for mechanical work is about 22-25% (measured on a bike) and about 80% efficient in intake (food -> fat). If you take that into account human energy storage is still several times better.
Meta: We never like to point out media bias of NYT, but have a bias for pointing out how biased anyone else is.

NYT gets a free pass.

Can you imagine a comment that starts with something like this:

“Oh look a NYT article where government is good." What a shock.

—-
But I digress. I agree, we should point out bias, but shouldn’t reduce the entire article to “What a shock”. Otherwise, we’d throw away every newspaper since they’re all biased. Right?
For me it happened randomly, but I think you can start searching for good content through good keywords or good people that you already know. This will create first good seeds and then the system will proceed with random improvements and through feedback loop.

Weather or not I care is really not your concern.
This was a great read. Previously I have implemented some IoT telemetry using a simple protobuf spec using delta encoding and batching a few samples together for each send, so it sends a lot of zeros.

Protobuf uses variable length encoding so most small integers will be sent as 1 byte. The first 16 in the spec use 1 byte overhead to show there is a non-zero value, and subsequent use 2 bytes. So you want to pack all your mostly-zero (or zero deltas) values at the end of the packet, and use the first 16 for your commonly changed values. And it's always useful to determine your desired data resolution and just convert a potential 8-byte double to 2 or maybe 3 bytes length integer (with a fixed multiplication). This also works storing in SQLite: use a View to read out the values in the end-format, and store them as integers in a raw table.

This was _good enough_ for what I was doing but it's great to see how far you can go if you need extreme.
Make your product freemium. You could even gradually move features into paid plans.
Is there another video yet?

The real achievement here is reading the old hard drive. He's recovered most of the software. Even cracked some old user passwords.

The machine is vanilla - it's a Motorola 68010. The peripherals are standard for the era. It might have some strange MMU, because it's from the era when Motorola had a good CPU but was years late with the MMU.
(If Motorola had finished a decent MMU out the door within 2-3 years after the 68000, the whole history of computing could have been different.)

The software could be run in an emulator, if anyone wanted to run that flavor of Unix System V.
ARM's HMP made sense for mobile devices like phones. I don't see any use for big.LITTLE designs on workstations or servers.
I keep hoping JetBrains will fold some of the interesting ideas in MPS into their more mainstream editors.

malleable code that remains valid on manipulation. Is there such outside graphical programming?
If you use TikTok for a while the algorithm will quickly figure out what you like to watch. It’s far better than the YouTube algorithm, for example.
This is a good development. In the last 5 Netflix-produced movies I watched the white heterosexual male was always the predator, women were the victims, and minorities were the saviors. Watch “The weekend away” for an example. At least they could continue from the 90’s and stick with the Russians being the bad guys. Why involving us white dudes /s
It's food for a specific niche though. More broadly, the US government does have a strategic grain reserve, holding wheat, corn, sorghum, and rice. Or at least, there was one, until 2008 when food prices spiked and the grains were all sold off. The reserve, called the Bill Emerson Humanitarian Trust, continues to exist to this day, but only holds cash/securities and no longer holds grains/commodities.
GP has already gotten a lot of value out of them, so if keeping them isn't costing much, I'd say grandfather them in for free.
Thanks.

What are some problems (or peculiarities that otherwise didn't exist) with the push based setup?

At another BigCloud, pull/push made for tasty design discussions as well, given the absurd scale of it all.

General consensus was, smaller fleet always pulls from its downstream; push only if downstream and upstream both have similar scaling characteristics.
It's a pay as you go model. There's a small base fee, plus costs that scale as you use it. Originally, I had a 2 tier model, for basic and premium. But the feedback that I got from the beta users was that it wasn't granular enough. People who used it less wanted to pay less than the tiers could offer. So I switched to the pay as you go model.
I mean, there’s always at least one reality where this happens: the one where climate disasters escalate to the point where human civilization is no longer able to extract new carbon to put into the atmosphere.

The goal is to find a different reality than that one.

Do remember that, while it does make coffee insipid, the milk some people add in theirs is a good source of vitamins, calcium and protein.
The fact that it has "calories" shouldn't deter them from using it, especially if, like most people (at least where i live), you aren't overweight, and do not need to reduce your energy intake

I do agree that coffee with milk has no taste tho
I'm a dev too, my machine is a dual core haswell.

It depends very much what you're doing of course (compiling linux kernel repeatedly perhaps) but if you have a little you can get a heck of a lot out of it with experience, although you surely will hit a wall sometime. But 32 cores not enough is just unimaginable for me.
We are all worsened if the cheap baby formula has a 20% chance of killing your baby.
This may say some true things, but I sincerely hope no anorexic person ever finds this article.
Just trying to figure this out.

So the low power high power cores do seem to be inspired by the M1. If they can implement that easily in x86 is another thing but if anyone can Intel can I guess.

The half prescion fps are obviously aimed at ML but how on earth are the hoping to compete with gpus on this front? Where is the use case on this (genuine question).

The complex numbers bit makes me think of quantum circuit simulation (but that could be bias on my part as that's what I'm looking at). But this is a relatively small field at the moment, and just through normal use nvideas backend simulator blows cpu performance out of the water (both for speed and number of qubits simulated).

I assume I'm missing the point here and it is heavily used in compression or something but again if someone had an idea of the usecase for complex number instructions that would be useful!
Thank you
I'm interested, what are you doing that can eat all those cores>
You know that experiment with the grapes and the chimpanzees? They gave chimpanzees 2 grapes a day for a long time, then gave them 3 grapes (for a week). Then they went back to 2 grapes and the chimps started throwing feces at the researchers.

When I was growing up, (nearly all?) online news was free and wasn't paywalled. It's only in the last decade or so that they started paywalling it, even for content from the "before time".

What was once free now costs money, and it feels like I'm getting ripped off, even though I might rationally appreciate that ad profits have gone down, or whatever the reason is.
Why do so many people use the head==tail as full condition?

You can use the entire buffer and not waste one slot by doing:

push:
buf[writeidx % bufsize] = x;

writeidx++;

pop:
x = buf[readidx % bufsize];

readidx++;

Unsigned integers, you get size by doing: writeidx - readidx;
Then you check size==0 or size==bufsize to detect empty/full.

So call them something else. What’s the difference? Microsoft don’t want an official looking store selling windows licenses just like Gucci don’t want it for handbags.

In the case of licenses they are usually even “real” licenses just repurposed e.g re-sold from defunct companies. The only thing bad about them is that Microsoft don’t want them sold. Which is understandable as they lose revenue when they are sold.
I ran into this as well. I had an attempted launch a month ago with a different pricing model, and people were pissed. They loved the product so much that they were angry at the prospect of having to choose to not use it (because they didn't like the price). I've since adjusted the model to fit all of the feedback that I gathered from that experience, and I've sampled the users to get their feedback on the new pricing model, and it seems positive, so hopefully there aren't complaints this time around.

Many of the testers do have free service (from referrals) that they'll get. But after that, they have to pay. I'm feeling pretty strict about it this time around.
It's nice that Google is releasing something, but the 3 datasets (https://crowdsource.google.com/about/open-source/) only cover only a fraction of the Crowdsource tasks:

Food compare: Compare the characteristics of two food images.
Response rating: Evaluate the natural-ness of a bot response.
Audio donation: Record your voice to improve speech technology.
Food facts: Tell us if a food dish has particular characteristics.
Food labeller: Tell us what food an image contains.
Semantic similarity: Judge whether two phrases have the same meaning.
Chart understanding: Judge whether charts are understandable and trustworthy.
Glide type: Glide your fingers on the keyboard to type the text that you see.
Audio validation: Listen to a short audio clip and determine if the pronunciation sounds natural in your language.
Image label verification: Tell us if images are tagged correctly.
Image capture: Collect and share photos of your part of the world.
Translation: Translate phrases and words into different languages.
Translation validation: Select which phrases are translated correctly.
Handwriting recognition: Look at handwriting and type the text that you see.
Sentiment evaluation: Decide if a sentence in your language is positive, negative or neutral.
Smart camera (Android Lollipop 5.0+ required): Point at an object and see if the camera can guess what it is.

Even in those 3 datasets, Google does not disclose the proportion/percentage of the crowdsourced contributions that are released publicly. I would not contribute to Crowdsource with the expectation that my contributions would help build a freely licensed dataset.
It seems when transferring pictures they are converted to jpeg/jpg and not as heif.
It won't work for my product. The costs per user are too high.
With some software work, you could pair differing cores. You'd just deliver a signal to a process saying 'youre about to be moved to a different core type, please recheck the capabilities'.

Then, you'd have a compatibility shim that emulates unimplemented instructions using traps for software that hadn't yet been rewritten to understand the above signal.
They’re trying anything to make themselves look like they give a fuck versus what they actually do when push comes to shove
It's a good idea, and one that I've run during the closed beta. A handful of the users have a referral credit for referring other beta users, and once we leave the closed beta, their credit will go into effect. I plan on extending the referral program after the launch as well.
Thank you for sharing this. While the police-brutality against black people were indeed very unfortunate and in no way justifiable, BLM is more like a political vechicle of a particular political agenda. Very unfortunate fact..
Both, sort of. The secret sauce to M1 battery life is a combination of OS thread scheduling and efficiency cores. The secret sauce to M1 performance is having an architecture that doesn’t need to be thermal throttled as much as in other platforms.

It’s not that Apple invented chips that are remarkably faster than Intel’s or NVIDIA’s, it’s that Apple invented an integrated experience on this new architecture with split performance & efficiency cores and did so while maintaining backwards compatibility with macOS x86 apps in a way that’s indistinguishable from M1-native apps. (So they kept the “baggage” as it were, and it still performs fine.)

I expect Microsoft’s Surface line will catch up eventually, but the disconnect between Qualcomm/Intel as chip makers and Microsoft as OS vendor will slow down the transition for a good 4-6 years easy, and we’re 2 years into this transition to ultra-energy efficient architectures with less thermal throttling. (Full disclosure, I’ve a few Apple shares.)
The politics are important to understand, but it’s insensitive to bring this up in the context of an individual soldier’s account of this situation. Like, great work with the virtue signalling, you’re very clever and informed. Maybe try reading the room a bit and being a bit more compassionate toward people who have no influence in these politics?
What's happening in the Burp-verse – Issue #11
When I tried the alpha version I remember they were transferred as HEIF files. Perhaps they've changed it recently, but AFAIR there's a setting somewhere on iOS to change the image format. Do you have it set to JPEG somehow?
The top Alder Lake desktop CPU has 16-cores, 8P+8E, compared to 8P in the 11-th gen. The E cores get around half the performance of the P cores, so the 8P+8E is get roughly the performance of a hypothetical 12P+0E CPU. The very high core parts are reserved for Xeon (a 56 core Alder Lake Xeon has been leaked, but I think the P/E split is still unknown).

What people need to realize is that a P cores takes around 4 times the die area/transistors of an E core, and use probably 3 to 4 times the power of an E core, but performance is only around double that of an E core. So with the same area, you get of the 8P+8E you can get 10P cores, not 12, and the question is if a 10P (rather than a 16P or even 12P) core Alder Lake is better than a 8P+8E. (Btw, these ratios are pretty similar as those for the Firestorm/Icestorm cores in Apple's M1.)

If your workload is very parallelizable you get more bang from your silicon and Watts with E cores than with P cores. If you have only embarrassingly paralleled workloads, you're probably better off with 32E cores than with a 8P cores.
Thanks for that. Really excellent.
big.LITTLE preceded the M1 by a long while.
Note: published in Scientific Reports means no good peer review.

>At baseline, time watching (r = − 0.12) and socializing (r = − 0.10) were negatively correlated with intelligence, while gaming did not correlate. After two years, gaming positively impacted intelligence (standardized β = + 0.17), but socializing had no effect.

>... Broadly, our results are in line with research on the malleability of cognitive abilities from environmental factors, such as cognitive training and the Flynn effect.
Google is making a lot of money on Maps. The consumer app is free only so you feed them free data from your rides. They also kicked out of business all competition (hard to compete with free). And as usual with monopolies, when there’s no competition, you can do what you want. Wait for it. In few years it will be shut down or will cost a lot if they no longer can sell your data to someone else.
Intel had a similar keyboard/mouse app. The experience was seemless and elegant but it was scrapped.

I've tried KDE connect but it does not compare, and is often a little buggy.
I think they added air, too.
I don’t completely agree. A MacBook Air M1 is 25% faster than a 10th generation Intel 10700K, running the same code full of floating point instructions and matrices. It’s not a simple matter of process node.

The same MacBook Air can do hour long Skype video calls with ~9% charge consumption, with no discernible heat difference on the body too.

M1 is a different beast.
They're not actually a process node ahead. Intel 10nm has slightly better density than TSMC 7nm.
Absolutely free things make people behave irrationally! Given the right prompting a free t-shirt and a "50% off your next coffee" voucher would be sufficient to hire an international team of assassins.

I bought ffp3 masks on 20th Feb 2020 since I could see what was unfolding. A month later my coworker accused me of panic buying. That was just forward planning? At no point was I panicked when I clicked the buy button in the freely available mask products.
Pretty much the latter.

This wasn’t Jackass, it was a science programme and he was the resident engineer. In theory he knew what he was doing but underestimated the risks and paid the personal consequences.
But on youtube I can just search for the topics I want to watch. Leys say I want to watch some age of empires games, I just search for age of empires and maybe some civilizations for them to play and I'll find hundreds of videos to watch. How long would it take to get something similar on TikTok? Personally I don't think that will ever happen. And age of empires is still relatively mainstream, many of the other things I regularly watch on youtube just have a few thousands of views per day in the entire world on that topic, how long would it take for TikTok to figure that out?
I have no experience with setting up pricing for stuff, but I feel like it could have helped if you already had pricing information in place before your free beta, even if it was just an estimate. Make it clear it won't stay free forever, you know?
the source of these pictures are all from ukraine. it's not far fetched to think they removed era and planted inert spacer to demoralize the enemy. in general, while the fog of war is in full effect, I wouldn't trust any one-sided intel.
KDE Connect has the problem of having KDE in the front of its name, which really limits its adoption. I'm deep in the Linux world and I only recently found out this app exists, works on GNOME and works on anything which ain't a KDE phone - I don't even know if it's a thing.

KDE developers really like their brand name, or at least putting a K in front of their name.

The picture (perhaps multiple but at least one) was a piece of hay poked right through a telephone pole, in the aftermath of some kind of storm. Not a tree. It was shown in grade school in the 80s or late 70s.
A Fun Bug? Help Wanted
My understanding is that Intel boosts power so a single core can chew through a program quicker than being inherently energy efficient (performance-per-watt). Most of the time this benefits Intel, because a core will boost-up-then-down quicker over completion of the program than a more efficient AMD processor core.

(This is my layman understanding.)

I solidly believe AMD is the king for efficiency, but I wish I could find better benchmarks showing idle power use for AMD vs Intel (not peak power use). My understanding is that Intel has deeper power states its processors settle into.

I'm surprised someone doesn't artificially limit or undervolt their Intel proc to approach or surpass what we're seeing from AMD. Would it significantly lengthen the total execution time of the program? Would there still be a significant difference in "performance"?

Performance-per-watt is important, and the total amount of power to execute the program. Would this be in Kilowatt/hours?

I want to see how many Kilowatt/hours something like Cinebench consumes on similar AMD & Intel processors, so we can derive the "real computing efficiency".
I gave away quite a bit of free labor to Google and niantic as they were launching ingress. If I had known that pokemon go would eventually be a thing, I might have thought a bit more about the power I had to shape where people would be walking every day for the next 10 years.

I guess basalt particles will sink. But if sinking is slow the top layer will get murky absorbing the light.
Yeah I can't fathom why you are doing this.

If the marginal cost is zero (i.e. this is software) they are worth more to you than any kind of incremental fee (i.e. assuming a few dollars a month, not thousands).

It's just one of the most fundamental rules of business that increasing prices is one of the most disastrous things you can do where there are expectations.

It's why there are granfather contracts all over the place.

Make your new customers delighted with your product at 'some price' and your 'alpha/beta' people feel empowered that they get it for free. You can sell them addons later.
Also the context is missing for the $0.01 Hershey’s Kiss. I wouldn’t stop for sweets in a supermarket sample offering if I had to pay for it but in a controlled study I would make a decision between the two chocolates.
