For most of the projects where the DB really mattered, throughout my 10+ freelancer carrier, it came down to one thing that client really cared about. Performance. Nothing else mattered, not license price, not whistles and bells, not hype. My clients wanted to have data in front of their eyes the same second when they clicked the button. And when you have a table with 100 million rows in it, and an application is not loading data from that table to show it to its users in the same second, you already lost the battle.

Out of my tries, my clients tries, and my friends tries, only one DB was up to this task. Not Maria, not Access, not Oracle, not NoSQL, not MSSQL, not MySQL - all of them failed. The only one was PostgreSQL.

And before starting to bash me, please do this. Make a small application that will show a map, put 100 million points of interest on that map, that are contained in the table we talk about, and now as you scroll the map, select the middle of view as your circle and select on a small radius only those points of interest inside that radius. No more then a thousand points of interest, lets say. When you do that within a second, you got yourself a good database. For me PGSQL was the only one capable to do this reliable.

I heard that’s why several countries denied testing initially even when symptoms matched: “you can’t have coronavirus because there’s no coronavirus in <country>.” Which is rather stupid considering <country> can’t “have” coronavirus if they just deny testing.

I'm pretty sure it is on by default: I'm both happy and paranoid about this.

I've found a phone using this. The spouse left the phone on the car: It fell off a bit past where we had stopped. This was on a mountaintop, in the countryside, traveling back from Sweden to Trondheim - not too far from the Swedish border. Location services meant we could head out and look for it. We could see if it was moving (it wasn't, so it likely wasn't stolen) and we were able to use my phone to find his. It was pretty accurate, even in that location. The phone was only a few months old. It had some scratches, but was otherwise fine. (I think the screen is now going out, but he drops his phone regularly at work and the waiting time for a new screen was 5-6 months to get the screen).

But I do understand that it means that governments could track us: Companies obviously are and I shudder to think of a motivated, angry ex or a motivated stalker. Turning the phone off doesn't help, and I don't know how far "turning off tracking" goes since there are ways to get, at least, a general location using tower information. I keep hoping that it'll turn into a greater good sort of thing, but this will only happen if governments change laws to better match people's behaviors so long as they aren't endangering others. I don't think that would happen in the US without major change, but I have hope where I'm at.

I agree, but how to monetize?
The book is not hard to read. Each chapter is written independently and hence the chapters can also be read independently. Each chapter presents in an accessible manner some ideas taken from a couple of Lamport's seminal papers.

In this sense, I believe reading Paxos from this book (chapter "Chapter 4 State Machine Replication with Benign Failures") would be much easier than reading Lamport's "Paxos Made Simple" paper. Actually, chapter 4 is a great read even if you know Paxos.
I don't agree there is a common definition of end-to-end encryption. Ask a random, non-technical co-worker what they think it means and you might get an answer that matches Zoom's marketing claims.

Uh no. You definitely can.

MVC isn't unique to those frameworks or languages. It's just an architecture. You can find many MVC frameworks in js.

Secondly, you don't need MVC architecture to build HN. You can use a different pattern and still have a server side rendered app that reloads on each page click.

Also, afaik HN uses firebase to expose an api. You can directly store data to firebase from client side. So you still don't need those full stack frameworks to build HN.
You are the architect of the application. If the application requires distributed database then it's your task to implement that in order to fulfill client's requirement. PGSQL has nothing to do with your skills and/or capabilities to comprehend said situation. You can do distributed database even with Access, or even with simple files.
And this is something that should be a call for change in government, a call for change in leadership, and a change in how the laws are structured. Perhaps better police/FBI training. And so on.

I'll also mention that these things are memorable because they are outliers in general, and sometimes spectacular. This is why we remember plane crashes and ignore the numerous shower accidents that kill folks.
Well I was 18-19 so to me these were myths I heard re-told.

But all I know is that they had been throwing hardware on a MySQL install to make it work better.

He migrated them to postgres and they got much better performance and could get away with less hardware than they had with mysql.

I'd be willing to bet that at least one of the participants was using Firefox. Jitsi unfortunately currently has a bug that drastically lowers performance for everyone when Firefox is involved, which is why some instances are blocking it.

Strange and snarky comment for a "Chief Technical Officer". Software constantly evolves, it's a process of continuous refinement.

Zoom's past success may have been partially attributed to "1st gen engineers" hitting the jackpot. Zoom's fate right now rests on the ability of those "2nd generation engineers" to keep the show going.

It's just a form of guided meditation where you focus your attention on the practitioner's touch, so it does exactly what meditation does (which is potentially relaxation, reduction in anxiety, reduction in pain perception, improvement of mental health).

> I mean if you just want to ignore the fact that all over Europe, you can pay rent, buy groceries, and live your life solely by using bitcoin, then I guess there's no arguing with you.

That's a massive exaggeration. I can guarantee you 99.99% of landlords will not accept Bitcoin as payment. Most major stores will not accept Bitcoin.

Are there a couple of hipster places in major cities that may accept Bitcoin? Sure, presumably you can waste your money exclusively dining and shopping there, if that's your thing.

Pretty much nobody is going to do that in their daily life though, except to write one of these "I lived only on Bitcoin for a month" blog posts. That's because Bitcoin sucks as a currency. Right now, a single transaction to go through in about ten minutes will cost almost a dollar. It's just not practical.

Of course you can also get one of these Bitcoin credit cards and pay almost everywhere in the whole world. Again, that's not Bitcoin used a currency, that's Bitcoin used as a gimmick payment platform.

> ...sick in November....

An acquaintance of mine was actually sick in November with COVID-like symptoms. They had a dry cough that was so nasty, doctors tested them for whooping cough (pertussis) and it was negative. And, it actually was not too long after their office got a visit from some overseas partners from China. IIRC, they even said one of the Chinese visitors had a bit of a cough at the time. I think this is pretty strong circumstantial evidence that they may have had the virus. At the very least, it's enough evidence that this person should definitely get an antibody test as soon as practical.

Edit: I initially forgot to include that the pertussis test was negative, although that was certainly implied.

It merits skepticism. But, is it a lack of the scientific method that's motivating the backlash? Or, is it that the claim falls within an unpopular marginality?

The obvious rebut is that it's unpopular, because it lacks scientific method. In other words, mainstream is mainstream due to merit and can be used as source of truth. If anyone takes this view, I hope they're very conscious of it, because in my opinion this viewpoint can't last long.

It's even worse if you use iMessage. If you take out your usual SIM card to replace it with a foreign one, people can't iMessage you anymore, unless they use your Apple ID (email address) for it.

It depends a lot on the implementation strategy. Some databases have GIS features, allowing you to query all points within a radius directly. I know oracle can do this, but it’s a paid addon (spatial and graph) and I don’t know how well it scales.

On databases that have good scanning behavior you can use a geohash approach instead. Insert all points with a geohash as key, determine a geohash bounding box that roughly fits your circle, query the rows matching that geohash in their key, run a “within distance” filter on the results client-side. I used that approach in hbase and it could query really fast. I suspect it would perform well on pretty much any mainstream sql db, but admittedly I haven’t tried it.
John Gray: Why this crisis is a turning point in history
Hi, mediasoup co-author here.

TL'DR': Pornhub uses mediasoup.

I've read many comments here asking about "how mediasoup is different than XXX" or about "mobile apps". I think the Overview in the website should be self explanatory, I'll just paste a fragment here:

https://mediasoup.org/documentation/overview/

---------------------
Design goals of mediasoup and its client side libraries:

- Be a SFU (Selective Forwarding Unit).
- Support both WebRTC and plain RTP input and output.
- Be a Node.js module in server side.
- Be a tiny JavaScript and C++ libraries in client side.
- Be minimalist: just handle the media layer.
- Be signaling agnostic: do not mandate any signaling protocol.
- Be super low level API.
- Support all existing WebRTC endpoints.
- Enable integration with well known multimedia libraries/tools.

Use cases:

- Group video chat applications.
- One-to-many (or few-to-many) broadcasting applications in real-time.
- RTP streaming.
> ...Ediger and his team dropped molecules one by one onto a surface as if they were Tetris pieces, allowing them to find snug fits.

Let's assume a 40kg super mirror was made from the same base silica[1]/tantala[2] substrate as the legacy mirror. Let's also assume 50% distribution by mass.

That's a (20kg/60.08g/mol)+(20kg/441.893g/mol) ~= 378.1mol tetris endgame.

So if we took this analogy quite literally and wanted to build 1 mirror in 10 years, you'd have to play precision atomic tetris a mere 17 orders of magnitude faster than this guy[3].

Not going to lie...sure does make watching grass grow sound a lot more pragmatic.

Agile Project Management Tools for 2020 [Ultimate Guide]
TBH, that should be easily doable for any database. I've built something like this with SQLite and on another occasion with Elasticsearch (where it's obviously much easier). If you leverage Geohash, and precalculate the geohash for every location, you don't even need any builtin geo-capabilities from the database.

Keep in mind that building an ecosystem up is sort of a lifetime-scale project, so we're mostly talking about rather un-controlled experiments running for decades. A more recent book I'm going through that I like is Martin Crawford's
"Creating a Forest Garden: Working with Nature to Grow Edible Crops"

In the section on soil fertility, you can find tables quantified in terms of pees per area, depending on the breakdown of what you already have planted.

He avoids the term "Permaculture" because like "organic" or "bio" it's turned into this whole badly defined spiritual thing, instead of just being about growing as much food as possible, with as few inputs as possible, with perennial plants.
In my experience when people are able to "fix" performance issues by moving from sql database a to sql database b it's because they understand database b and how to optimise for it. Not because the database is better or worse. My company was "saved" moving from postgress to mysql. The difference was the guy and his specific knowledge, not the database technology.

i wish there was a management layer that runs and operates high availability postgres databases on AWS/GCP/Azure...but is significantly cheaper.

AWS RDS makes it impossible to export snapshots to s3 (because the native snapshot storage is super expensive).

RDS db.m5.xlarge w/ 5000 GB costs 1000$

Why is there no SAAS that lets me BYO my own EC2 and just runs and gives me a dashboardy experience ESPECIALLY for snapshots and restores ?
mediasoup is a SFU that must be deployed in a reachable server, so STUN is not needed at all. You may need a TURN server if a client has a restrictive firewall that blocks UDP. mediasoup is not a TURN server but you can deploy a TURN server (i.e. coturn) in your backend.
Configuring is stupid. People need to be able to work in different environments, so software needs to do the right thing by default.

Email doesn't distinguish between messages that can be actioned by any one of a group and messages that need to be actioned by you specifically (there are a bunch of unreliable hacks that sort of work most of the time). So you're never going to be able to get the right notification behaviour in a reliable way.
I don't code in node, nor am I a developer. The overhead of using a package manager, when I can copy and paste just feels unnecessarily.
