> They're not "meaning" anything, they're literally saying that adding an index sorts the table by the indexed column, with a little picture showing this change to the table itself.

No, I don't think so. That's one interpretation of what they said. Since that's clearly not correct, why should we assume that's what it means? That's dishonest reading.

If I'm explaining to a beginner how an index works -- which is literally what this article is doing -- then I don't see why I wouldn't refer to an index as a specially sorted version of the records in the table. That's not a huge difference from what the author actually wrote. Yeah, you might prefer that the author had said "organized" rather than "sorted", but those two words are synonyms in plain English.

Look, here's the statement in context:

> What indexing does is, sets up the column your search conditions are on, in a sorted order to assist in optimising query performance.

> With index on company_id, table would look like this <image>

> Now, due to sorted order, the database knows which records to examine and when to stop.

> The main point of having a index is to cut down the number of records/rows in a table which needs to be examined by the database, to speed up the searching queries.

If you look at an index physically, it does literally store the values being indexed. That's why indexes take up disk space and require I/O. They're actually duplicating information. It does actually take the column values from the table and "sort" or "organize" the columns covered by the index. They're organized into a B-tree [usually], but the values from the table for the indexed columns are there and they are organized in a way you can describe as "sorted." The big difference is that the pages of the index, rather than having leaf records like a table, instead reference the records directly (often using an identifier tied to the clustered unique index).

I don't know if this is common, but I have a lot more missed audio bits in Facetime than I do in other apps when I talk to my family in a third world country. I suspect what you are saying is correct. Modern apps are built for the weakest link while Facetime is built for the strongest.
Definitely easier to use than any of the alternatives. An intuitive video calling system should do just that: video (and/or audio), not chat.

Firstly; she has not heard of WhatsApp, it would have to be taught to her that it is a chat app that has additional functionality to allow phone and video calls.

Blank stare.

She does not chat and has no interest in doing that.

The UI of WhatsApp is confusing and unintuitive if you assume you know nearly nothing except that you want to make a video call.
Not to completely minimize it, but that says local attacker, not remote attacker. So someone would still have to gain access to the system in question in the first place.

I assume "tear down 1 unit, build 5-10 units" is OK? Otherwise, what you're suggesting just leads to more suburban sprawl. There isn't room in SF, NYC, etc for infill development (from vacant lots) at the scale necessary to make a dent in housing prices.

Beating 2FA is almost always SMS hijacking, but sometimes it's social engineering where the attacker has figured out just the right script to tell support ("oh, I dropped my phone and it won't turn on...") to get it disabled.

Forgive me - I typically try to adhere to the ideal that posts on HN should be constructive and refrain from snark and sarcasm, but this particular comment chain has become so circular and repetitive that the only response I can think of at this point is, “No shit!”.

This is just an empty ad hominem.

Is the data accurate or is it inaccurate?

Is the interpretation of the data valid or is it invalid?

Either SpaceX is or it is not involved in a lot of close calls in orbit. These are not facts up for interpretation, they either are or they aren't.

Whether a given rate is alarming or not is a value judgement, certainly, but if there has been a significant increase in rate, and SpaceX has been responsible for that increase, then the facts speak for themselves.

So, what is your take on the facts as they've been reported?

You said "the only visual data that needs to be sent across network is the positioning of facial features and hand movements". To extract facial features and hand movements is non-trivial and requires video analysis and may hence involve lag.
This is a philosophical gap that society in general needs to bridge.

Data is truth. If we discover bias in data that tells us something about the world. I can't fix systemic racism with a SQL statement. But I can tell you where it happened.

Society can decide what classes are protected and data can tell us when that happens. It is then up to the offending entity to change their behavior.

In other words bias in data isn't unethical but bias in action can be.
it's the other way :D, since i bought the house in 2015, my gains are paper gains (~200%), but my property taxes are real loses, since they've grown almost twice as well.
Humans look to others as sources of truth and use them for examples to base their behaviour on. If there were no other people around and a person had no emotions at all, their eating and sleeping would become irregular, just like these flies, because there is nobody giving them cues about how to act. This isn’t really evidence of depression imho, but does show they have social awareness which is neat and which makes sense
That's pretty much what I said in my last line. The problem is, "opening up more" generally tends to mean things like less masking and less social distancing. So to the extent that Rt is pushed down by mitigation measures, Rt gets pushed back up when those mitigation measures end.

So, in the short term, you have some pressure for high promiscuity/low intelligence, but over time you'd have a very fragile society, and the slower reproducing more intelligent society would be more successful in the long run either because it obliterated the less intelligent ones in war, or just because it was able to overcome things like natural disaster, child mortality, hunger, cold, heat and disease

my son (not yet 14yo) has learnt to write a few games in Roblox

he's learnt Lua, object orientated programing client side/ server side distributed programing (and how to optimse the speed)

he's also learnt that the people who run the platform will screw you over in many different ways (he's learnt a few tricks to semi counter this)

he's learnt that advertising can be useless and costly,

learnt people are extremely fickle, there's a far amount of people who have money to throw around

learnt that doing good graphics is harder than it seems.
(also learnt how to use blender)

also that game dynamics and subtile changes can have big real world changes to peoples experiances

also that UI and UX are important

also to train other (kids) how to program - for money

I'd say as a learning platform it has been fantastic, he's not made much real money, but has earned a far amount of robuks (platforms currency) that's he's spent in game
The guy literally launched his own car (that his car company produced), into Mars orbit using a rocket that his other company built.

Both of these companies have become the largest companies in their respective fields and can arguably be labeled the two most complex and highest barrier to entry industries. Sending humans into orbit has only been accomplished by large nation states, no company has even done that besides SpaceX. As for car manufacturing, it’s been over 50 years since a new competitor has entered, and only Ford and Tesla have never gone bankrupt.

To anyone trying to argue this isn’t the most accomplished human alive, give me a friggin break
The speed of deposition is super variable. In fluvial environments, I've seen reports of feet per year, which put recent sites (i.e. medieval) under 40+m of sediment.

Under which encoding is this part of the article true? In any given Unicode encoding, isn't it either the case that U+BF27 doesn't contain the byte 0x27 or that U+0027 does contain the byte 0x00? In really obsolete encodings like UTF-1, I guess the principle is correct, but I still can't find any where that particular example actually works exactly as described.

I have a dark suspicion that their best target market might be to pretend they're not algorithmic, but actually being so.

Most people, almost by definition, have rather ordinary tastes. They will want to imagine that it's slightly better than average, but not outrageous.

I don't know much about fashion, but I see it a lot in food marketing. Restaurants differentiate themselves on trendy but safe choices. It works down from the high end: Gordon Ramsey splashes something with truffle oil, and a few years later you can get New Burger King Truffle Fries. A lot of "mom & pop" restaurants are just heating up things off of Sysco trucks.

I don't mean that to sound snobbish. People should enjoy whatever they like. I'm slightly turned off when it's marketed as being really innovative while smaller, more interesting things languish, but that's just the market at work.

As it applies here, I suspect that most people really could be very happy with algorithmically applied clothing. A truly personal stylist would be much more expensive and outside of most people's comfort zones anyway -- unless they did basically the same thing as the algorithm.

What Stitch Fix can offer is the illusion that you're being truly stylish without any of the risks. Which is a fine thing, as far as I'm concerned, if it makes them happy. That excludes a market which really does want a truly personal, human stylist, but I suspect that market isn't nearly as large, and even smaller if you ask them to pay what hours of attention would really cost.
So true. That fact that people consider it normal to commute from Fredericksburg, VA to Tysons/Ashburn/Reston is bonkers.

Fredburg to DC isn't quite so bad - at least there's commuter rail and slug lines. But exurb-to-suburb commuting should never be something that's encouraged.

And FWIW, we downsized to a TH to be closer to work. Couldn't be happier. I now walk to work; my wife cycles. We're in walking distance to all local schools. And a short bike ride to dining and shopping. I don't know why more people don't do the same. The house cost was in the same ballpark as the single-family we owned previously.
You're focusing all on the math, but nothing on what it means to the person. Three questions:

1. How much are your monthly expenses?

2. How much of that is your mortgage payment?

3. If you had no payment, what would you do with that money?

Let's take an example:

1. Monthly expenses are $10,000 a month.

2. Mortgage is $4,000 a month.

3. If you had an extra $4,000 a month, you could work part time and volunteer more at that coding camp.

3. Because you have $80,000 saved, you could take a 6 month road trip, and still have time to find another job.

3. You could use that for one of the 15 side projects you've been thinking of.

3. You could go on a fancy vacation every year with your family.

3. All the while, no bank can evict you from your house, because you fully own it.

Are any of those things really worth foregoing extra 4-6% rate of return? For many people, they are. All it takes is no payments.
Does average monthly salary mean much if the majority is really poor? Assuming you are middle class, here. Also: you probably mean iPhone 12. The 6 is quite old.

I remember my 6 very well as I fell on my motorcycle and I pulled this banana shaped phone out of my pocket.

It is more like comparing the game to real life to see how they hold up and teach how real life works than using a game simulation to say that's how life works.

I disagree too.

HN's layout is plain and simple and effective. It loads fast and unlike the vast majority of websites these days, it actually loads all its content from the same domain. I'm so sick of popping open uBlock Origin's inspector panel to block junk on so many websites these days and finding that the site domain is little more than a blank frame which loads in all its content from dozens of external domains.

Fascinating blog post. However I don’t know why it took him so long to reach out to Facebook support, everyone knows that to get your account unlocked you just need to write a viral blog post about your experience and use your existing popularity to ensure someone at Facebook reads it, realises you’re not one of their typical peasant end users and unlocks your account for you.
> Many people seem to solve the "automate DNS" by putting their DNS credentials on the server which serves their website. This is the worst thing from a security perspective.

Indeed. That's why I have a single machine that I use for running acme. (Maybe people don't realize that you don't have to run the acme client on the same machine where the certificate will ultimately be deployed?) It contains all my keys (ssh keys, acme account keys, API tokens) in an encrypted database and a set of scripts for getting updated certificates and installing them. This machine has no open incoming IP ports, only outgoing SSH and HTTPS connections. It also contains copies of all my source code and deployment scripts. I could in theory tear down my entire production infrastructure and rebuild it with a single command from this machine.
Google is better than all other alternatives in that regard. They have a feature called Advanced Protection where you add your 2FA U2F keys and if you lose them your account is gone. No social engineering possible.

When I got my Covid shot at Safeway they asked for it. I just didn't fill it out and no one even asked for it. I still had the record show up in Washington's vaccination DB, so it wasn't for that either.

I hope them asking for it didn't discourage someone without an SSN from getting their shot, since immigration status isn't relevant to eligibility.

I don't think Facebook 2FA is terribly secure. They definitely err on the side of usability. I was using TOTP on Instagram and I forgot to backup my Google Authenticator before wiping my iPhone. But I was then able to just go the the settings on a logged-in device and disable 2FA without 2FA. And it wasn't like I had logged into that device recently, either. I only had to 2FA Instagram once, years ago.

> The average price of American homes, in real terms, is now the highest it's ever been

I understand that the price of a stereotypical suburban home is well out of reach for many and this isn't great and should be worked on in a smart way. The middle class has continuously been hammered for many reasons and it would be healthier for America for this to be improved dramatically and better for individual communities for people to have a real stake in the well-being of the area.

Just to throw a few devil's advocate points into the mix, I believe a full and complete economic analysis may show that the price per SQ foot of residential living space per person may actually be about the same or even less than it was in the past. I think some variables that need to be considered are the increasing sizes of homes, the decreasing average family size (many siblings in the past had to share bedrooms, which I believe is far less common today), and inflation, among others.
> Beating 2FA is almost always SMS hijacking

That's most definitely not true, as someone who works in this space. Plain old phishing is much more common, where the hacker tricks a user into entering their code into a malicious website.

To echo OP, this is why it's important to support non-phishable types of 2FA.

Adult with ADHD here: You would not develop ADD from media. That's not how this works.
