How does this compare to the “official” Jupyter desktop app: https://github.com/jupyterlab/jupyterlab-desktop

The scanner uses some neural nets and an IR camera to see if everything around the iris checks out. So you can’t (easily at least) scan some disembodied eyes, or your dog’s eyes.

The orb does a round of “liveness” checks before the retina imaging to ensure someone’s not trying to scan their dog / detached eyeball.

Theodore Gray, cofounder of wolfram research, was responsible for notebooks I believe.

I wrote the Notebook user interface for Mathematica and led the user interface group for over 20 years.

It allows iCloud or obsidian syncing. I tried to set it up with Dropbox because I didn’t trust iClouds conflict resolution and couldn’t get it to work.

With proof of stake, a complete chain history is not strictly required by validating nodes. You don’t want everyone to delete it, but it’s not required for consensus.

I believe they’re treated as byte sequences: https://go.dev/ref/spec#String_types

I’d imagine they would, kind of like the levels of arbitrators and courts today.

The article said the neighbours first vote that work is done. Most of the time that could work. But it also mentions the neighbours could collude to steal the collateral. In that case courts could get involved and force money be returned etc.

I’m very far from a legal expert, but smart contracts seem like a potentially useful tool, within the current system. Not as a complete replacement.

HN is basically the “Dad internet”.

They’ll instinctively shoot down all your ideas, but their accumulated experience is helpful once in a real discussion.

The example in the article had a way to enforce contract breaking - the person had to put up collateral until the work was done.

There’s problems with that particular mechanism, but in general if contracts can automatically decrease someone’s money, reputation, access etc, they can do enforcement.

I think with any weird new technology, fundamentally no knows if it’s going to work.

People who can’t see or imagine use cases become sceptics.

But others who piece together enough observations to tell themselves stories of why it will work become believers.

But neither can explain why the tech will or won’t work, so we end up with technobabblers and angry sceptics.

I suspect that blockchains won’t need to reference external data to be useful.

If the data on chain becomes valuable enough, an ecosystem of open source, auditable programs operating on it seems powerful to me.

And yeah tx fees are facemeltingly expensive right now, but scalability tech is making gradual progress.

I think professional software devs won’t get much value from copilot.

OpenAI’s demo from a few months back showed it as a sort of bridge to convert natural language instructions into APIs calls. Eg converting “make all the headings bold” to calls to a word doc api.

Most of the comments here are opinions on what other people should do to stop climate change.

For those that have read up on it, What are the highest impact things the average hacker news reader can do over the next few years?

The flickering is concerning. Kind of suggests their NN hasn’t learned basic object persistence yet.

An iPhone 12 weighs 164g [1], so, through the magic of the metric system, it needs to displace a minimum of 164ml of water to float.

The iPhone has an external volume of 14.67cm * 7.15cm * 0.74cm = 77.62cm^3 = 77.62ml. So it would need to be about 2x the volume to float.

It exploded mid air just after landing burn started.

In this video you can hear engines start then an immediate explosion https://mobile.twitter.com/TheFavoritist/status/137689513012...

Possible the burn started late right above the ground. But I reckon we would have seen a larger explosion on the cameras in that case.

- The passphrase for the Trust Wallet is saved as a screenshot on his iPhone.

Could the photos have been uploaded to iCloud and compromised from there? Or accessed from another device?

Keep the python brand and fix these things in a new backwards incompatible python release. Call it Python 4.

I’m sure it’ll only take a couple of years for everyone to migrate

I feel semver combines two separate ideas into the meaning of v1:

By labeling as v1 you're:

- communicating the package is stable and will be maintained

- communication that breaking changes will now increment the major version (saying nothing about stability, backported bug fixes, or any maintenance)

I wish they were not combined. Incrementing major versions frequently on early stage projects would make them work better with package managers, but without the expectation of maintenance from the community.

Not incrementing major versions makes it hard for package managers to make sensible decisions.

A consequence of the complexity is that some devs stay below v2 forever because it’s easier. Backwards incompatible changes pile up in v0.x’s. It’s then really difficult for consumers to install two versions of the same package, which can happen with diamond dependencies.

I think I lucked out with a strong stomach, though I do perform better on days I eat after exercise.

Just to counter all the early-bird routines here:

Wake up 1130, muesli, start work 1200.

Lunch late afternoon depending on hunger, about 30 mins.

Work until 2000 or 2100 then get some food

High intensity excerise for 30 mins, shower.

Then depending on energy levels either more work, side projects, or just browsing internet from 2300 to 0200.

FYI, the basic features mentioned are available in plain macOS.

Remap caps lock to control in system preferences.

Then ctrl-p: up, ctrl-n: down, ctrl-b: left, ctrl-f: right

ctrl-d for forwards delete, also ctrl-a/e for home/end, ctrl-u/k for delete line forwards/backwards

Works in almost all text entry boxes with no config or other software.

It could definitely help a lot of unbanked people. But that seems to be a nice benefit rather than the core mission.

From the white paper:

"Libra’s mission is to enable a simple global currency and financial infrastructure that empowers billions of people."

They do this by issuing coins in exchange for fiat money, which is held by the reserve.

"Interest on the reserve assets will be used to cover the costs of the system, ensure low transaction fees, pay dividends to investors who provided capital to jumpstart the ecosystem [...]. Users of Libra do not receive a return from the reserve."

Conceptually this is a bank, but with no interest returned to users, no financial oversight from governments, controlled by Silicon Valley's top companies.

It’s targeted at countries that don’t have such wide adoption of credit/debit cards.

There's a very similar project called Interledger.

It uses the same mechanism of credit payments over multiple hops. But denominates each hop in a particular (possibly different) asset to help settling the credit between peers.
