You will need some sort of signal transport for sending ICE negotiation data in JSON. Because the two peers need to know how to coordinate how to connect to each other before actually connecting. It can be a websocket server, REST API, email, QR codes, carrier pigeon, etc.

Also in general, I highly recommend webrtc-adapter.

Time it yourself by spinning the bottle right after you begin pouring, and you will notice that it is still faster. ;)

It's interesting because in some parts of Northern Mexico, you would think that use of "tú" didn't exist. NO ONE uses it, not even relatives or husbands and wife.

My dictionary defines abuse as "cruel and violent treatment of a person or animal". What is cruel specifically about setting expectations about what needs to be done? There is nothing cruel about requiring kin to call you sir especially when you can show that you deserve their respect.

It's an authoritarian parenting style, and I don't think anyone really likes it. But there's nothing here to suggest any marginal physical or emotional abuse. I personally know a few traditional Mexican families where the father is addressed as "sir" as a sign of respect but still knows how to care for their children.

It's probably too late now to make it easy. At that age, I wasn't particularly inspired to do things my parents didn't enjoy doing. This article[0] suggests it's around 1-3 years old (toddlers).

Does it work without a mobile data connection? Regardless this is a great idea and I would love to know what it would take to convince other banks to do the same.

I'm halfway into the video and it seems like an impressive use of half a million lines of code. The developer(s) is a UV artist himself and says the algorithm's process is close to how he would do things himself. He discusses the entire algorithm but it comes down to identifying different features like hard flattish surfaces, cones, strips, smooth surfaces, etc and handling them independently.

It's probably not open source. It says email Quel Solaar for licensing. He is targeting game studios before moving on to film vfx studios.

Yes, I plan to let him know soon!

EDIT: I found out he is providing extra credit for textbook errors.

No, in section 3.4.1.1 General-Purpose Registers in 64-Bit Mode of the Intel® 64 and IA-32 Architectures Software Developer’s Manual, it says, "32-bit operands generate a 32-bit result, zero-extended to a 64-bit result in the destination general-purpose register."

`xor eax, eax` actually generates 0x31 0xc0, and `xor rax, rax` generates 0x48 0x31 0xc0. 0x90 decodes to xchg eax, eax in all modes except long mode, which has no effect. In long mode, the opcode 0x90 has no effect still but is no longer equal to xchg eax, eax.

Do they usually go in detail about what happened after they figure things out?

I agree that it's not convincing. But I think over the phone it makes it close to indiscernible.

New comment by eboyjr in "Highlights from the OpenStreetMap conference"

eboyjr — Tue, 28 Aug 2018 03:55:03 +0000

tldr; There was a State of the Map event July 28-30 in Milan, Italy.

There was a lot of discussion of vector tiles and that eventually the homepage of OpenStreetMap.org would use vector tiles.

There are a few tools for fighting vandalism, but they aren't at the level of replacing a human editor.

A new data model for OpenStreetMap was discussed and there is discussion to whether they should improve the current one or replace it entirely.

There is a proposal for a new public transport schema to help make routing problems easier while also making it simpler for mappers to use.

Grants to the OpenStreetMap Foundations helped bring reps from underrepresented communities to the conference. Also, gender diversification was discussed.

What kind of technical support does one need for an app like this? These people apparently need oh so much help with navigating it's many features.

I've been using it for a while now. The new position of the new tab button on the top left take some getting used to but I do think it looks really great.

Ask HN: What are my options for interviewing and negotiating advice?

I am currently approached by a startup who wary of working with me because of schedule conflicts from my university courses. They would like to know how much money I am expecting for this job. Of course I have many questions for approaching this. Should I offer to work hourly? Should I 'pro-rate' my salary accounting for the hours I would be available to work? What kinds of arrangements can I expect will be suitable for a similar company?

What I would really like to know is: Aside from posting here, I think the general audience would like to know what resources are available for working through this. Are there companies who provide this? People in the community?

It would be interesting to know why they get these country names. And I would guess most people here know that french fries were created in Belgium.

Good to hear that the Earth is settling somewhere that it won't affect us instead. This is newsworthy to me if it decreases the likelihood of new earthquakes in the area.
