Actually, Skype was designed from the start to use e2e p2p communication. First thing after the Microsoft acquisition was to remove e2e and introduce dozens of new features no-one actually asked for. In addition, they turned the UI into a d

As long as each single project keeps reinventing their own Lego stubs, we won't be going forward with reuse. With Haskell and Scala's type-system we seem to come closer to universal Lego. Still, like Lego, it can be hard to combin

That quote is misattributed and I also think it is not something Dijkstra would have said. Quite the opposite actually. However, I think this quote from him is much more beautiful: In their capacity as a tool, computers will be but a ripple

Then provide useful, technically complete, secure alternatives that are vetted by the government. The expectations of your employees are changing, so the technology you provide should change along.

After Okta rudely told us, a paying customer, to pay extra or leave, we decided to survey alternatives. Four years ago, we found Keycloak and never looked back. It’s stable, customizable, well engineered and relatively easy to work with.

Yes, of course that number is sacred! Just ignore all the following examples: there are four bases in our DNA. Most animals have four feet. The vallancy of carbon (basis of life on earth) is four. We have four fundamental forces. The New Te

Reflects my thoughts exactly. Also, all the amenities are overcrowded. I've seen photos (while doing research before writing GP) and I can't imagine having to stay in such an invested place for longer than a day or two.

The cruise industry is one of the most polluting and damaging industries in the world. It ruins cities worldwide. Their ships are petri-dishes for disease, spreading it directly into our vital cities. They are blocking perfect vistas of the

Policy makers are often incorrectly or selectively writing experts to push their agenda. Confidence intervals become averages. Multi variate predictions become univariate. 30 year models become absolute truth. No wonder people lose trust.

I used (many years ago, with Mnemosyne) spaces repetition on CS and AI history. It is really useful to have this extra context available during my normal activities. It allows me to see modern development in a historic context.

HN is not Wikipedia. I am more than happy to provide evidence for my claims, but I'd be downvoting almost every single comment on HN if those were the requirements. The CFR is easy to find with a Google search. There are multiple studi

The estimates seem to be reflected by international numbers to a certain degree, ranging from 1%-3%. With the disease in exponential growth, dividing #death/#cases is not the right calculation to make, as it might take 3-5 weeks before

Well, this [1] is an article describing extensive GGO [2] and subpleural parenchymal bands in recovered patients. I have read other reports from Wuhan doctors describing these effects, but some search terms seems to be censored these days.

This is way more serious than the flu in multiple ways. First of all, estimates show that the case fatality ratio (CFR) is around 2%, which is 20x higher than the flu. This number is likely to rise when ICUs are becoming over-constrained an

As such, it helps to also study 4NF and 5/6NF (which are temporal normalisations). This allows us to refer a sale to an earlier 'version' of the product.

Your question is interesting from the perspective that the actor model could be seen as the precursor to modern object oriented programming. Both the actor model as defined by Carl Hewitt and the early object computational models as they ar

YAML is probably the least ergonomic configuration format available. [1] Even XML would be preferable, as at least most XML parsers are interchangable. [1] https://www.arp242.net/yaml-config.html

I am not an expert on the hydrogen economy, but I've consistently seen a couple of important road blocks. First, like you mention, the transport and storage of hydrogen is complicated due to hydrogen embrittlement of iron and steel. Th

Estimations work when dealing with symmetrical distributions. You might be wrong either way. But these distributions are fundamentally not symmetrical! Also, you should compare deaths with number of cases a couple of days ago (like 7), sinc

No, it does not give any information for a multitude of reasons. 1. Deaths are lagged by known cases 2. Both are skewed distributions 3. These people might have received professional care when it was available. During an outbreak, the avail
