You can look for slow queries, then try to understand why by getting the query execution plan. You can alternatively also look for queries with a high standard deviation, which can hint of queries that get slower as there are more rows associated with a user.

Once you have the execution plan, you can either optimize the query, optimize the schema (add indices), or simply optimize the application (e.g: narrow the scope of the query, reduce call count). That however, won't allow you to horizontally scale.

The only realistic way to horizontally scale is sharding. Replication will slow down your writes as more machines are added and that simply does not scale. Using the same database for everything and everyone is a lousy way to go. Eventually you will need to keep things on different machines at some point.

Then, don't put large blobs into a database and store just the blob IDs in your database. Use another data store for that. Analytics, logging, etc doesn't belong into an OLTP database. Use another database for that not your OLTP one.

Seeing it here too. Curious that I haven't heard anything from Google about this. Usually whenever there's any kind of temporary outage with a Google service we get spammed with tens of emails letting us know.

I think he correctly points out, though, that the games industry and culture have a massive self-esteem problem. For the most part, when it gets kicked, it just lays there and takes it. He may be a touch effusive in his positivity about games, but it's for a reason.

You can argue the gaming subculture shouldn't care what people outside of it think, but it's too often been picked on and used as a scapegoat for societal ills. Ignoring that kind of 'opinion' is a bad idea.
I think Apple seriously underestimates its appeal towards creatives. I've been buying Apple products for 10 years because of their ease-of-use with creative software. As they slowly move away from PC's and professional media standards I see their market share diminishing.

They are heading down the path of lowest common denominator just like Microsoft in the early 2000's. I expect the same fate awaits them as someone else fills that role.
I don't have any issues with the battery life of my 6S+, and I'm not sure there are any other phones with a substantially better battery life on the market. I know there are a number of Android models that claim 24+ hour battery life, and so does the 6S+. I do know that a number of Android models ship w/ a 3,700 mAh battery while the 6S+ ships with only 2,950 mAh, but the real world usage claims have them in the same ballpark.

My last Android (Samsung Galaxy Nexus) had AWFUL battery life (3,700 mAh battery, btw) and I had a couple of spare batteries with me at all times. My iPhone 6S+ gets me from 0500 to bedtime nearly every night without a charge throughout the day. According to the release notes I should expect another hour of battery life with the iPhone 7, so it's not like they took things away and decreased the battery life.

For me, and that's all that matters in MY buying decisions, better durability and extended battery life at the cost of a port that I have never used on this phone are an unequivocal upgrade.

I wonder how much of that "premium" segment is owned by Beats? Regardless of their quality, this CNN article[0] claims that beats owns a quarter of the total headphones market and over half of the "premium headphones" segment.

These other stats claim that Apple & Beats, combined, account for 70% of future purchase plans for teens.[1] Th definitely have the edge with regards to marketing.

And also, looks like just recently Bluetooth headphones are outselling wired headphones.[2]

With Apple controlling Beats, and Beats nearly controlling the headphones market, I still think this problem will end up affecting a mere niche demographic one year from today.

Unless these were gifts, you paid for them. If the phones were "free" or just a penny from a mobile carrier, the real price of the phone was hidden in the monthly service charge. That's why you had to sign a long-term service contract to get the "free" phone.

Thank goodness the carriers have been moving away from that kind of deceptive pricing.

Hi, former non-US student here, I got an internship (J1 visa) in a US university in a lab. I got it thanks to one of my teacher. He knew a US professor and gave me the opportunity to talk to him. The professor did not even need a new student in the lab, but I proved him that I could be useful (showed some of my projects). The university took care of most of the paperwork. I hope this can help you.

Users remember their emails, they don't always remember their nicknames especially if they had to select an alternative nickname because the one they usually chose was already used...

Honestly, it's ruthlessly pragmatic business reasons. Is it ideal? No but in the end, it's the most painless for most users...

And, also most users on that particular site have little computer experience, so it does affect how they react and how we work. If it were something targeting the HN crowd, I'd probably have enforced email validation and would see a much lower drop in conversion due to it because people on HN are used to that and do not have a problem with it.

So, validations and UI workflow have to be adapted to your audience and your business and that's the main point really.

In this particular case, we did experiments with enforcing email validation for a subset of new signups or even allowing a small number of signups to signup with a username instead of an email. So we do have data...

Most of the work I do for other customers doesn't touch those areas of their app, so I only have relevant on hand experience on that particular site but I think it's important to mitigate the recommendation of "Always validation emails" or "Always use regexp" and try to think of the best experience for the kind of users you're targeting.

Sometimes in HN, people talk in absolutes when things are instead very context-dependent.

I'm deeply confused as to how you misinterpreted my comment so much. I was explicitly referring to (2) which is why I quoted that in full. That's also why I explicitly said "So if I'm renting out my home on AirBnB, or even a full floor of a 4 family brownstone...".

Maybe, but neither of the links you provide are "on this topic", (to wit, the legality of discriminatory renting via a commercial intermediary like AirBnB.) Both are regarding discriminatory listings via hands-off listing venues, which is a very different issue.

The point is the referenced constitutional right to "intimate associations", and you have not established that the use of AirBnB somehow nullifies this constitutional right.
Could you maybe go over some experiences of your PhD that are orthogonal to those of Karpathy? I'm really interested and I'm sure there are others who are as well.
> Anything over 2ms is not acceptable for live music. That's the difference between a band sounding "in-time" to "needs practice"

Obviously you want your in-ear sound to be as exact as possible, but a 2 ms difference will not make a band sound bad. I remember hearing 9 ms was the threshold for live music, but I can't find any references. If it truly is lower I would love to read some source material.

There are very few people in the world that would be capable of playing within a 2 ms tolerance (but maybe you're just holding you in-ear reference to a higher standard to allow for human error).

Edit: here's an interesting resource, not much data but they did find problems start between 10-20ms.

Perhaps that's why the pragmatic programmer book was so big on text files for everything. Even if all you have is grep and find they'll work.
It would be so easy to beat this though (if you want the analog hole route), ultimately that gets decoded and sent to the speakers in the headphones, rip the headphones apart.

Unless they start doing serious hardware anti-tamper in headphones I don't think it's a real risk.

No, it should not. Security involves policy decisions; for instance, "how should I respond when confronted with an expired certificate with a valid signature", or, "how should I handle a certificate when I can't verify whether it's been revoked", or "how should I handle a valid certificate for a pinned domain".

Sometimes the answer is "just go ahead but lose the green bar".

Sometimes the answer is "pop a click-through warning". (We click through these warnings, but they bounce significant numbers of end users).

Sometimes the answer is "scream bloody murder to the browser vendor".

What does it even mean to trust a signature? Do we trust things that come from hierarchical PKIs? Would we rather rely mostly on key continuity, like SSH does? Do we want to build something like Moxie Marlinspike's Convergence, long term, so we can choose which authorities we trust?

All of these concerns that I listed could be handled in an encryption capability that resided directly in the transport layer. But we'd inevitably come up with concerns that were difficult to handle there --- for instance, if it's part of TCP/IP, the code is mostly kernel resident, and maybe it's super hard (even harder than it is now) to get Curve25519 deployed.

This isn't so much insight on my part as it is the stated conclusion, about security in particular, of Saltzer, Reed, and Clark's "End To End Argument In Systems Design", which is one of the foundational documents of the Internet:

http://web.mit.edu/Saltzer/www/publications/endtoend/endtoen...

Push things as far towards the application layer as they'll go, and keep the lower-layer protocols dumb, so they don't get in the way.

Here's a more reasonable approach that probably addresses the concerns you have about there being multiple app-layer crypto protocols:

> When you plug an audio cable into a smartphone, it just works.

No, hardware-wise you're still going through a DAC, and the complex audio subsystem of the OS is still deciding, upon receiving the connection signal, to re-route the application audio through that headphone DAC. Or not. Jack or Lightning doesn't change this.

> Apple can choose which manufacturers get to create Lightning-compatible audio devices.

Sure. Or you can use the included lightning-jack adapter and just use normal, un-DRM'd headphones.

>Once Apple gets the ability to add DRM, the record industry gets the ability to insist that Apple use it

See my first point: the audio jack wasn't your last guardian of freedom.

>In other words, if it’s impossible to connect a speaker or other audio device to an iPhone without Apple software governing it

Use the adapter. And see the first point.

> the only way to connect an iPhone 7 to a recording or mixing device will be over the suboptimal Bluetooth connection or a dongle provided by Apple.

Aha! They finally acknowledge the adapter! But do they acknowledge that it's functionally identical to a built-in DAC?

> It's possible that iOS or specific apps will be able to disable the dongle.

It's also possible the phone will halt and catch fire if you run an unapproved app. But disabling the dongle would be moronic. For one thing, they'd be incurring the wrath of ADA-defender groups.

>the converter you rely on to hear your phone on your hearing aids—just became less useful.

See previous point.

>But you shouldn’t have to depend on a manufacturer’s permission to use its hardware however you like.

Then don't even buy Apple. They've been locked down in so many other ways for a long time.

Anyhow.

The simple explanation (see Occam's Razor) is that the designers noticed that they were using valuable internal space for a redundant connector (considering the hardware has been able to route audio over Lightning for a long time), and figured they could reclaim that space for something else. Clearly, people disagree with this change. The market will tell.

>> When any evidence comes out that shows that a specific portion of UG is probably not true, they crow triumphantly about how language is really fundamentally something ineffable and pseudo-mystical, not able to be computed by logic.

I think the overwhelming mass of work critical of Chomsky treats it as a computational object; the emphasis changes from global computability to local inference: what can a learner infer about the structural properties of a language? How can people parse complex sentence structures and ascribe meaning to them? Hence the rapid adoption of machine learning for explaining human behavior in psycholinguistics, developmental linguistics, and historical linguistics. Nothing pseudo-mystical there.

Nothing.

The question is, who is going to win: the legion of teenagers and young adults who listen to audio via the headphone jack, or device makers?

(It's the legion.)

If you had a replacement that was better - cheaper, less of an annoyance than $5 headphones plugged into a cheap phone - then you might win. But the proposed replacement is superexpensive, battery-powered wireless headphones. When the no-strain-relief Apple cables break, probably within weeks, you're supposed to buy another superexpensive set. That's not going anywhere with the horde of teenagers. It's a non-starter.
1. Apple has already publicly stated this is not about DRM and, at least when it comes to music, they have been very anti-DRM for a long time.

2. Apple earbuds aren't the only one's you can use. There are lots of lightning compatible headphones and they've been around a while.

3. This is not 'The End of Headphones Jacks'. It's one phone manufacturer. Globally iPhone market share is less than 20% so if you want a headphone jack you have a lot of great options.
I assumed it had a DAC, but can't find a source that says either way.
