> Bargain scope, not time

I've started applying this and it's amazing how well this works.

Of course sometimes it's just not possible to reduce the scope any further, but the key point is that the stakeholders just want something, anything and as soon as possible at that.

You give them that and suddenly there's much less pressure and you can focus on delivering the rest, or sometimes dropping it entirely because in hindsight it wasn't that important.

There's a similar phenomenon occuring when playing planning poker - often the estimate is not what anyone wanted, but the one that the most could agree on, which is usually way off. I thought of solving this by having a single transferable vote, but I hadn't had a chance to play planning poker for over a year now, so I have no data on its effectiveness.

> I can’t explain why.

I think one reason might be that being interactive lets the player contribute to the enjoyment themselves, which lowers the bar for what the developer has to achieve. Give people blocks and ways to move them and some will have endless of fun building something creative whereas with a movie the author is responsible for making sure the blocks are arranged in an interesting fashion.

For me though I think a large part is also simply that I am more into games than movies/music so have spent a lot more time looking into the indie scene there.
What if instead of mapping positions to 2D points and finding the closest point among 9 samples, you mapped positions to 1D coverage values and picked the maximum value among the 9 samples? Would this make antialiasing easier to implement? What about using 4 samples rather than 9?

I'm concerned that the results turn a single point into a square rather than a circle. Would using non-square-grid point distributions alleviate this?

Perhaps this could be useful for GPU line rendering, though it's a texture-space algorithm and won't solve drawing a thin line in the first place (which I don't know if it's easier than a thick line or not).

I recently discovered a problem in this domain of modulo reduction. I'm looking for a way to create a smaller index for Ethereum accounts that are in the range of 0 to 2^160 [1]. It's mainly to reduce gas storage cost [3].

Most folks I asked about it, ended up concluding that I'll end up with this pidgeon hole effect where it'll become likely that an index is suggested multiple times [2].

It may not be super cryptographically-sophisticated: But what I want is a hash function that's (at least) somewhat aware of collisions without using too much storage. Bloomfilters were recommended - but it seems they need to much storage too. I need to be able to map Ethereum accounts to a smaller sized domain e.g. 0 to 2^32 to safe storage costs in smart contracts.

Since I asked on Stackexchange, the problem has become kind of stale and I stopped working on it. But it's fascinating and I should continue to dive deeper...

Interesting article! Thanks

RedVentures is pretty much the 1000lb gorilla in SEO lead gen. They also have a pretty large patent library and aren't afraid to use it. This includes a patent on zip code search which our last startup was on the receiving end of an infringement claim.[1]

If you are a reporter or investigative journalist I'd encourage you to do some poking around into the business model behind APlaceForMom.com and the FTC action to spin off Caring.com and the overall effect on the nursing home industry.

I can go on a major rant about RV, their moves to rollup the majority of the lead gen industry but due to prior legal interactions with them I'll refrain from painting a target on my back any further than I have.

> it’s good for software robustness that file formats and hardware use different endianness, as it forces you to read things byte-by-byte rather than lazily assuming you can just read 4 bytes and cast them directly to an int32.

Except that it is very bad for performance. As far as CPUs are concerned little-endian has definitely won, most CPU architectures that have been big endian in the past (e.g. PowerPC) are now little endian by default.

If all new CPU architectures are little endian this means that within a decade or two there won't be any operating systems that support big endian anymore.
If you continue to flood a country with people who are willing to work for lower wages, supply and demand for employment and wages will continue to work as intended. People look around and they wonder why for 60 years wage increase has largely stagnated. It's not a mystery. So then, unwilling to accept the root cause as one that must be addressed, some seek government intervention to artificially increase wages. Then you're left with a large and ever increasing supply of workers but the demand for workers will necessarily decrease because you can't just suddenly double the cost to run a business and expect the employer to say no problem, I'll have just as many employees as before.

We know this doesn't work because we've been trying it for a long time. It seems to me that some people, when faced with failed policies, will think "we just haven't done this enough yet." As though if we were only increasing the minimum wage even higher the effects would be the opposite of what we've seen in the past.

Right now, apparently, there is a shortage of labor caused by the government paying people more to stay home than they're worth to pay to do work. It's something to keep in mind. Work is only worth so much. It doesn't make sense for a fast food restaurant to pay someone $30/hour. So, when minimum wage increases, those people simply aren't hired. So now instead of whatever wages they might have been paid, they now make $0 (or however much is coming out of your taxes for them to stay home).

There are other factors like the cost of housing that make this more complicated, but "we just need to force businesses to pay people more" ignores many important factors contributing to this situation. Which is why nothing gets better. It's time to try something different, not double or triple down on things that just don't work.

I thought it was a reasonably conservative estimate. If you polled people, and asked them if they would give up being free from having to wear a mask in all settings where they have to interact with people outside their immediate family, for a 5% longer lifespan, I think we can safely say most would not agree to that exchange.

I think any reasonable estimate of the quality of life degradation caused by all-day masking would result in the conclusion that masking children does more harm than good.

But for the sake of argument, if we polled people, and found the value was indeed 5%, then would you agree that masking children does massively more harm than good? I just want to know if you hold the same logical axioms as I do, or else this exercise is pointless.

>>Sometimes people inconvenience themselves to help others (not just themselves).

But you're not just inconveniencing yourself. You're inconveniencing tens of millions of children.
In my observation unfair downvotes come, when people are angry at something and looking at anything that looks like a scapegoat to direct that anger, which can be anyone not expressing the same mindset they have. Which was you by asking that question that apparently was enough to mentally puts you in the "stupid treehugger camp". I would not worry about it too much and try to not take it personal.

Their rational explanation is probably "how you can be so stupid for not knowing that common knowledge".

And well, even though I am indeed a treehugger, I also knew about the efficency of dishwashers before and also assumed it to be common knowledge, but I would never downvote someone because of a genuine question adding to the conversation.

Indeed, reading file headers byte by byte also avoids alignment issues on some CPUs. At least older ARM CPUs trapped misaligned reads (not sure if this is still the case though).

These aren't colour images - they're all coloured after the fact.

What the sensors do is to take images in multiple wavelengths. Each individual channel is still monochrome and "real colour"-images are produced by interpreting them as red, green and blue with various weights depending on calibration.

If you look at the actual sensor wavelengths, you'll notice that they don't cover the same frequency spectrum as RGB sensors or human eyes. It's all interpretation and calibration (that's why the Mars rover have a colour calibration plate on them).

Another method (often used with astrophotography) is using a single monochrome sensor and put RGB filters in front of it, take separate pictures with each filter and recombine them (done on Earth).

You can see the frequency bands of the filters used in MERs Spirit and Opportunity here: https://mars.nasa.gov/mer/gallery/edr_filename_key.html

(the rovers used 16 different filters, so no RGB there)
This technique is not new. E.g. I remember it described in ARM system developer's guide published back in 2004.

It shows how to use unsigned 64-bit multiplication to restrict a range of a 32-bit random number generator to 0..N. No shifts are needed, as the result is in the upper 32-bit register.
Not that it matters now, but I’ve recently learned about generic-data-surgery [1], a library that let’s you take a record X and return a record X with an added field Y. Pretty cool stuff, considering it’s all strongly typed. You would need to do the JSON serialisation _after_ the addToken step, but that shouldn’t be a problem.

The UK was actually considering giving the Falklands to Argentina before the war. The invasion ruined whatever goodwill was there, justified the costs of maintenance, further legitimized those opposing a potential handover and rationalized further security spending.

If there's a common thread here, it might be the use of an external crisis by the Argentine gov to deflect from domestic problems. Of course that depends on your perception of the CCP. Some regard the CCP's governance as non-problematic and wouldn't agree.

Marc Andreessen on Investing and Tech
You are correct. NASA employs artists to generate published press images.

The individual pictures sent by the spacecraft are indeed monochrome images taken with different filters. These filters don't usually correspond with RGB and calibration is required to approximate human perception.

Most of the time there's no equivalent at all (this applies to pretty much all deep space imagery) and the colours are basically made up (the intensities aren't - they correspond to frequency responses, just not necessarily within the human vision spectrum).

Here's a discussion on the topic: http://ivc.lib.rochester.edu/pretty-pictures-the-use-of-fals...
The ubiquity of this issue really points to a deeper, admittedly unsolvable issue: morality is not a shared value of significance. Every discussion of security assumes that the primary threat is a purposely malicious actor, not an accident prone one. I understand that people see the shared morality issue as an unsolvable one which is why we try to solve the problem at the software/hardware level. But that looks unsolvable too (as per the article).

> You are knee-jerk reacting to keywords you have been taught to hate

Quite the contrary, my french culture and education has taught me to have great respect for authority and for startup nation bullshit newspeak. But since then, i have developed some form of critical thinking.

> You need to work on that, first of all.

I tried. In their publications section, out of 7 items, there are: 2 that don't have a link; 1 about text/image similarity analysis; 1 about sentiment analysis; 1 about situated knowledge and the "user-researcher"; 1 that's behind a paywall (the one describing the EUNOMIA project); 1 that's not even a scientific paper but an "information hygiene" guide

In their "Deliverables" section we find more information. I find it strange that documents are labeled "Dissemination Level: Public", or "Type of deliverable PUBLIC" which suggests acquaintance with the surveillance/military industrial complex, as originally exposed in the critique linked in the article i was mentioning: https://hub.libranet.de/wiki/paulfree14/The(20)critical(20)E...

From these documents, a few quotes which may raise eyebrows:

- the [blockchain] framework offers embedded mechanisms for preserving privacy with the use of digital signatures and cryptographic hashes

- each information element that it is stored in the P2P distributed file storage a specific token will be generated by the Storage Serve

- The AAA Server is responsible for the authentication, authorization and accounting. Any entity that wishes to connect to the EUNOMIA infrastructure needs to communicate with this server.

- The Discovery Server provides means to allow the discovery of other services and corresponding metadata, including their public keys

- deleted posts will be removed from associated cascades, P2P databases and the EUNOMIA Blockchain ledger
Most scientific astronomical images are based on capture of specific bandwidths and frequencies, which are then assigned colours for visual interpretation.

Given that many of the frequencies are beyond the limits of human vision (ifra-red, microwave, and radio, at the low end, ultraviolet, x-ray, and gamma-ray at the high), this is somewhat out of necessity.

The individual channels largely record intensity, so in that regard they're similar to B&W photographs, but the intensities are of specific bands, rather than a wide range of bands as in silver-halide based photographs. There may be some frequency variation recorded and interpreted as well, I'm not certain of this.

That said, I'm pretty sure that there's also an eye to aesthetic and public appeal of landmark released images.

This link shows and discusses multi-spectral images, showing the channels individually for several objects:

I didn't say anything about consumers caring whether a program was written in C++ or Rust, and I don't think consumers care about that. I talked about whether the product is full of memory unsafety or not. Where that is a relevant aspect of your product, Rust is far, far more productive--it's more or less impossible to produce a large C++ program without exploitable memory unsafety bugs, while it's fairly tractable in Rust. Where it is not, I expect productivity gains to be modest at best.

My point here is that there is pretty much no sized team that will deliver a C++ program with equivalent functionality to Rust, when considering security as part of the feature set. We know that about 70% of CVEs in memory unsafe programs come directly from exploitation of UB, that there is no commensurate increase in CVEs in safe languages, and that only about 1% of LOC is unsafe--so weighing the percentage security bug reduction is pretty easy. But not all customers prioritize security very much, so Rust's benefits over C++ in this context will have to be downgraded according to how highly they value a 70% reduction in CVEs. That is why I said it depends on the product--you can't come up with a flat "productivity" metric, like you seem to want, that applies the same to every situation.

Romania as it is today only formed in 1918 but its three major provinces Transylvania, Wallachia and Moldavia managed to stay distinctively Romanian through out their history.

Before WWI the nation found itself positioned at the crossroads between three major empires and during its tumultuous history suffered from their repeated attempts to dismember the country.

It did not benefit from the favourable geographical position such as Britain had, nor from managing to expand and conquer new territories, which always meant bringing back riches and slaves for the colonising country.

This is a nation which has endured a lot and deserves some respect when its history is brought up.
