halpert commented on Dino 0.3: Video calls and conferences – encrypted and peer-to-peer   dino.im/blog/2022/02/dino... · Posted by u/larma

From the article:

"Peer-to-peer calls require more bandwidth than calls routed through a server and are thus not suited for a large number of participants. In the future, we plan to also develop calls via a forwarding server to solve resource issues on the client side and to allow for calls with more participants."

It's even worse than that. P2P means that connection differences between peers also makea difference. User A might see users B and C, but user B might on see A due to a connection difference between user B and C. It is very annoying to enter a group chat and hear:

User B: Is user C's stream dead for anyone else? User A: I see user C. User C: Sorry, what? I'm right here.

Honestly, other than a 1-1 chat, I can't think of a situation where p2p is worthwhile. Even then, it's almost always better to use an SFU.

Click-bate garbage. A truthful headline would have been “Company with 130 mil dollars US operational loss in 2021 expected to pay no federal tax.” Of course that wouldn’t get clicks and is not newsworthy at all.

It depends on why they have an operation loss. If they’re leasing the trademark from a Cayman island shell corporation, then that would be noteworthy.

Well, of course. It's zero-sum. For everyone who gets fiat out, there has to be someone who put fiat in.

The way they measured this may not be meaningful, though.

halpert · 4 years ago
The amount of fiat available, and it’s value is not constant so it’s not really zero sum.

If you use Go or gRPC, then you're probably using HTTP/2. I've seen both used, at least somewhat, by every company I've done work for in the last 5-6 years.

The default Go http server is 1.1, no?

P2P group video calls don’t work well unfortunately. Most people barely have enough upload bandwidth to upload one video stream. Needing to upload a stream per peer is a nonstarter for most people.

Yea exactly. This is survivorship bias - the prospects of today look at the winners of yesterday to guide their entry on how to communicate, they’re slightly more likely to get funded, etc

It’s reinforcement learning over decades

Emulating the past for success in the future is a form of idea homogenization.
halpert commented on Case against OOP is understated, not overstated (2020)   boxbase.org/entries/2020/... · Posted by u/tejohnso
taurath · 4 years ago
In my mind, state is the real enemy impacting: comprehension, brittleness towards making changes, and the surface area exposed to potential bugs. OOP as frequently implemented, while claiming to encapsulate state, ends up creating so much more.

In accordance with this view, I think project architecture should be approached with an emphasis around how much state is necessary for it to run. This is why simulations like say someone making a game or simcity with like relatively independent entities that map to something in real life use OOP. If you're writing a service doing requests, you want as minimal state as possible. Singletons are state. Initialized/non-static objects are state. The smaller amount you have the easier it is to reason about the system.

As I write this however, I worry a little that my view is overly simplistic, or maybe applicable only to domains that I have worked in. If anyone wouldn't mind poking holes in this argument or offering examples I would appreciate it.

Sorry, but state is everything. If you don’t have state, then you’re essentially doing useless work computing an answer that is already known. Computation is only useful because of state.

PragmaticPulp · 4 years ago
> I find your warning a bit unfair as there are literally no CTA inside the blog content promoting our product

It’s obviously blog content designed to promote your product, hosted on the company’s product website. I don’t see how the FYI is unfair.

I added it because the content was valuable but HN can be finicky about blog posts from companies advertising their own products. Trying to get ahead of indignant dismissals.

halpert · 4 years ago
Where do they promote the product? It looks like they’re using a random http library.

Okay at the risk of being offensive, all the comments before mine are made by overly intellectual fools.

I'm not usually so insulting--but as a father of two, if my 3 year old and 1.5 year old could only read one book, it would have to be "Oh, the places you'll go" by Dr. Suess.

Sorry to stomp on Das Kapital and its ilk, but if you get only one book, I can't imagine a better first message to convey than the endless possibilities inherent in each of us.

The world is your oyster! Even if you're old and have wasted most of what you were given. Especially today, in some of the most amazing times that have ever existed (even if you didn't draw the long straw). Today is SO much better than most of history.

What’s amazing about Dr. Suess is how much creativity and fun he packs into a very simply written book. Most children’s books are so asinine. “Sally went to the farm. She saw a pig. Sally can drive a tractor. Etc. etc.” There is rarely a point to the book. Dr. Suess uses similarly simple language: “You can think about red. You can think about pink.” While simple, the underlying message is usually profound, and that makes it so much more interesting.
halpert commented on Gut microbe linked to depression in large health study   science.org/content/artic... · Posted by u/pella
aszantu · 4 years ago
Someone been telling me, my depression comes from bacteria, I KNOW! Pain is... if I eat something plant based, depression and suicidal thoughts come back. Takes about 4 days after I ate the offending food, stays for 3 days, then I'm back to normal and energetic.

Latest experiment was one teaspoon of fermented green squash daily, seemed to work out okay for 5 days or so, then depression came back, BUT I could smell it in my armpits 1-2 days before the thoughts were back.

https://gutsense.org has a lot about fiber - the only fiber I can use seems to be animal based, like eggwhites

halpert · 4 years ago
That seems pretty crazy. What have you tried to remedy the issue? Fecal transplant?
