It's pretty easy to run into render performance issues with React, especially on older machines, when you have a very dynamic UI. At work, we dynamically generate several SVG charts and "badges" on certain pages. Putting even one of those onto a page without any optimization created about a half second delay between actions on my high-end machine, so we had to spend some time making sure that things weren't re-rendering needlessly and that DOM nodes were getting reused. But even if that seems like an atypical use case, we had similar issues rendering complex tables, purely due to the amount of DOM nodes needing to be put onto the page at once. So it might not be an everyday kind of problem, but I don't think it's uncommon to run into performance issues with React.
> Remarkably bad at human and helping humankind.

I would say that the way how Uber aggressively expanded throughout the world has massively helped humankind. Because of Uber, many countries have changed their taxi laws, and many local competitors have sprouted up. More efficient taxi and ride-sharing services help save the environment and make cities nicer. Of course this is quite theoretical but I believe Uber was the needed company to push the mass transit development forward.
I always thought job loss was something that happens to other people until I got laid off despite being an ‘A player.’ Now I assume it is just a matter of time no matter the role.

This is the reality for everyone under at-will employment. Even if you are the best at your job, outside circumstances like changes in strategy, funding and leadership can make you a target for ‘managed offboarding.’
Not really at the early stages from what I can tell. There is definitely a correction happening in late stage pre-IPO and recent-IPO companies. In part because everyone is realizing that SoftBank are actually the dumb guys in the room, when the prior common view was that they were the smart money. A lot of these crazy valuations (Uber, WeWork, Slack, etc) that are getting cut were set by them.
Theres also a crazy amount of enterprise purchases who dont care about storage. Everything is stored off device, and an MDM is keeping whats on the device to a minimum.

Companies would still be buying 32GB by the truckfull if it was available. Apple was right to discontinue it because 32GB wasnt enough to run the OS anymore, while also being a usable phone.

Since you cant run a phone without iOS, and stripping the OS down isnt an option, I think they should be legally required to be truthful in advertising and sell it as a 50-55GB iPhone, probably 50 if they plan on using some of the space for device upgrades.
It's form factor too, not just price point. The form factor is the only reason I switched from Android, and I'd happily pay the full iPhone 11 price for a phone the size of an SE with iPhone 11 internals.
There's a new Apple Watch.

They run on investments (still haven't made a profit). If investors get shy (due to fear of recessions) then they have to cut back the pipe, and uber is forced to layoff.

Yeah I remember trying a demo that was literally trying to do this, just on our Mac Performa 5200 over a 14.4 modem (you had to pre-download the "map"). Even the design is eerily similar.
Some time, in not so distant future, we will have abundant, almost infinite, almost free, renewable energy. We will forget what an energy bill is, because administration overhead will be higher than the price of the energy itself. It will just be an inconspicuous tiny item on the city taxes. And we won't think it's amazing. We'll take it for granted. It will become new normal. Just like now we don't remember any more what it feels like not being reachable by phone when you go out for dinner with your friends.

I bought a new SE earlier this year, but managed to completely shatter the screen twice and gave up on it. Still holding onto a 6S.
There's a few libraries which implement this for all units in e.g. SI, like boost units or nholthaus/units on github. There's also the safe numerics lib in boost which catches UB and other issues around integer operations preferably at compile time and, if not possible, at run-time.

Different ideas for different people.

The general concept is, either it lasts for weeks or it lasts for one day, if it lasts for 3 days you'll forget to charge it, if it lasts for weeks it's okay if you forget, a small reminder can tell you to charge it enough for a day in a few minutes.

The trade off is insane in comparison, the Apple Watch is capable of a ton of things you just can't do in a longer battery-life product, things like phone calls, cellular connection, sharp graphics and quality voice replies. Meanwhile the garmin products have fantastic readability outdoors on their low res, low power transflective LCDs.

They simply are on a different roadmap and each roadmap has its own constraints.
I feel the same, I’ve had an SE since it launched. The devices released since then are just too big. I was hoping we would see something new in that form factor during today’s event.

11 128 GB - $749

11 256 GB - $849
Because the 128 a sweet spot and most people don't have a need for more. The 64 size is just enough to push most intensive users over the hump and in to iCloud subscriptions. I'm sure Apple has all the analytics on how much space is being used by their users and how much iCloud subscriptions would take a hit with an 128 offering.
Color me cynical, but 20-25 years ago companies were touting what the "future of healthcare" looked like.

They, and the people they were marketing to, would have been appalled if at the time they could have seen at what it became. At least in the United States.
Is it possible to have a softphone app on the iPod Touch?

You would just need a wireless hotspot that the iPod would always be connected to, to use it as a phone (or maybe people can start bucking the trend of always being connected).

It's the same size as the SE, except a hair thinner, and has a 3.5mm headphone jack!

Okay, but that's kinda like saying eating healthy is good because you get to deprive oneself of donuts: that is, I feel like it's mixing up the cost and benefit. The point of the work is (from what I'm understanding here) to make it less feasible for bots to flood a server with requests, but doing the throttling server-side would have the exact same effect more consistently (i.e. in a way that's not easily evaded by GPU/FPGA/ASIC acceleration and doesn't punish normal users).

I've just read all the comments here, it's a roller-coaster ride but is exactly what I saw with my self-hosted GL.

Each new release there'd be a new release with great new features - yay! - followed by 3-4 patch releases to fix the bugs. You eventually get worn down by it and don't bother using these things.

I see the same with other dual licensed stuff. Kong is a good example - bugs that actually stop routing traffic are eventually acknowledged, but with no feedback unless I keep chasing them. However i'll get regular emails with new products. They've got a new Service Mesh they announced recently. There's not a chance in hell i'll use it until they fix the bugs/issues i've reported in the core product.

You should re-read my post, as it wasn't myself that fears a recession is looming.

The broader discussions within the markets are that one is on the horizon. I'm not so confident.
RMI has been pushing hydrogen cars for a while. I was never a big fan of their analysis there - so take their conclusions with a bit of a grain of doubt.

Ironically gas and solar / wind sometimes go together with gas filling gaps in generation on a more flexible basis. Interesting to read here that gas will be "crushed". That will need some huge battery capacity - not saying its not possible but...

Coal though - if article was coal is going to be crushed - sure.
> People should also be aware that disabling DDIO comes at a significant performance cost. So far as the researchers know, chips from AMD and other manufacturers aren't vulnerable because they don't store networking data on shared CPU caches.

Again, performance gains leak sensitive data and the solution is to disable some features (and loose performance as well). Seems that Intel chose between performance x security, and security lost.

> Intel DDIO is enabled by default on all Intel Xeon processor E5 family and Intel Xeon processor E7 v2 family platforms. (from https://www.intel.com/content/www/us/en/io/data-direct-i-o-t...)

Seems that it was used in 2012-2014 processors, so it's an attack on 5-years-old processors. Perhaps the impact isn't that great nowadays, but I couldn't find it the same attack can be made in more recent CPUs.
They spent a lot on R&D and bet the company on kickstarters. Their direction also constrained them to Garmin-like products rather than heading off Android Wear or Apple watch (even fitbit can't compete after buying their guts)

It's not so simple, because energy consumption is restrained by its cost. There are also grids that will need expansion and maintenance, and both solar and winds need either baseline energy backing (such as nuclear or gas) and/or storage.

If her iPhone 5 is still running iOS 6, she is correct.
I think it might be a reaction to either a) what amounts to the same story with a different name over and over or a reaction to b) a number of stories that seemed to be out for blood against tech.

Epstein had connections to rich and powerful people in tech... And entertainment, and politics, and really all industry.

I think it's just a hard story to keep up with. Too many connections without enough investigation to if those connections are tied to his crimes (yet).

Now you have a giant phone, tons of photos, and no backup. People with the bigger phone are probably more likely to be buying the extra $36/yr, not less.
I'm not antenna knowledgeable nor plasma knowledgeable.

Is there a layman's explanation about what the advantages / why there are advantages here?

It talks about turning off the plasma antenna, is that any different than simply not using a regular antenna? ... or what they mean by stealth or "resistance to electronic warfare and cyber attack".
Thats why no one talks about it cumulatively. By cumulative logic every new iPhone release is the most interesting ever by definition because its... cumulative.
>there are no compact Android phones either

On Samsung Galaxy S6 and later models, one can tap the home button three times to shrink the screen so that everything can be reached with one thumb. It's called "one-handed mode". I can't say I've used it very often, but when I need it, it's there.
If you see "useWhatever"... then it has a hook.

And you already have to wonder if a function has state if you didn't write it. If you did, you should know.
> Caltech doesn't have demographic quotas; there's the exception.

They don't have quotas, but Caltech has gone to considerable effort to lower the male/female ratio to address the problems mentioned in my comment.

They were male only before 1970, and then started admitting undergraduate women. When I was a student there, in the late '70s and early '80s, around 15% of the undergraduates were women, and this imbalance was the #1 complaint by far among both the male and female students about campus life.

Caltech worked on improving this by actively recruiting female students. They didn't change admission standards or give any preferences to females when evaluating applications, but they tried hard to make sure than more females applied, and that those accepted didn't pick another school over Caltech.

For example, as a male with good enough grades and test scores to get into Caltech but only about average for an incoming Caltech student, Caltech was indifferent to whether or not I applied, or whether or not I accepted when they offered admission.

For a female with the same grades and test scores, they would have reached out and tried to convince her to apply, and there is a good chance they would even have sent someone in person to argue the case for Caltech to her and her parents.

These efforts paid off, with the male/female ratio steadily improving. They are now at about 55% male/45% female.
People wouldn't have booed because other than journalists, the theater was filled with Apple employees.

"Of those laid off, more than 85% are based in the U.S., 10% in the Asia-Pacific and 5% in Europe, the Middle East and Africa, according to the source."

Interesting. This hit seems to be mostly localized to the US. During their last mass layoff in July, employees from all over the world were affected.

> If we get healthcare spending down to 11.3% of GDP like France, we still have to find about $2 trillion per year in taxes to cover that cost.

Are you asserting $2T in taxes is somehow worse than the current $3.5T we pay for healthcare (taxes, premiums, out-of-pocket)?
Neat. Either is quite possible. When I wants to change jobs, I cast a very wide net. Last time, I did on-site interviews with something like 14 companies.
He was absolutely instrumental to the early success. In some places they were actively breaking the law just to operate there, and Kalanick was able disrupt the system and make Uber important enough to change the laws.

However, that doesn't mean he should still be CEO. Kalanick also created a company culture that became more and more toxic as it grew larger. Lyft was arguably on the ropes and might've failed without the #DeleteUber movement caused by all of the Uber scandals. Without Lyft for competition Uber might actually have the pricing power to be profitable now, but as it stands I'm not sure how viable they are in the long-term.

I use AutoSleep on Apple Watch 4. It is good at poking me after a few days of not sleeping enough with a message like: "You slept for 5:38 last night, and have a sleep debt of 12%". That's enough of a poke to get my sleep back on track.

I've also used it to experiment a bit with how drinking at night affects my sleep. (noticeably!). I could do that with just how I feel, but the hard data is easier to correlate later.
So you're officially saying that it will be too cheap to meter?

As you surely know, that's been said before, mostly about nuclear fusion and fission breeder reactors, both of which have inexhaustible resources. What's different this time? There's still absolutely massive amounts of major equipment needed in a wind/solar dominated energy system.
I agree it's not intuitive at first. As someone pointed out on Twitter (can't find link at the moment):

A good mental model is that the second argument to useEffect defines which pieces of state that effect syncs with.

useEffect(() => {}, undefined) // Sync with all state

useEffect(() => {}, []) // Sync with no state

useEffect(() => {}, [a, b]) // Sync with `a` & `b`

People who want to take high quality pictures and don’t really care about video.

32GB of video at 4K is still ~2 hours of video at 30fps. I take a fair amount of pictures, but I don’t think I have taken 30 minutes of video in the last 4 years.

Yep. You don't find many EEs left in the US these days, unless they work at a military contractor. All the electronic hardware design work went to Taiwan and China, because that's where all the manufacturing for it is. What's left is government-related (military) stuff that obviously can't be outsourced to Asia, and some commercial stuff that they keep in-house for various reasons.

Basically, the US is a really bad place to be an electrical engineer specializing in electronic hardware, but it's a great place to be a software engineer or developer.
Uber and Lyft are not necessarily efficient. This SF study claims increased pollution levels https://advances.sciencemag.org/content/5/5/eaau2670

I don’t get why Uber isn’t profitable. Their marginal cost is only higher than zero because they choose to lose money.

Their fixed costs are servers and engineering. If they set their prices higher than what drivers are willing to accept they should make money.

I don’t see how “basic economics” is the enemy. Their enemy is setting expectations too high. If they were happy with a profit of $100M a year they would be sustainable forever.
These sorts of threads appear for every announcement. I chuckled seeing another user claim that it wasn't exciting because they didn't have something like Animojis to announce, that feature being a desperate "please try to buy this phone we're trying to justify this awkward face unlock thing".

It's an incremental update that also brings huge new features to the "low priced" version. And it'll do great.
Came here to make the same comment.

I don’t think Apple has confirmed any EOL for the SE. It’s not sold in the USA anymore, but isn’t it still produced in India for that market (maybe ending now that the 11 is announced, I’m not sure)?
> Now we're instead having a discussion about Android phones and Animojis?

Because you & apple during the presentation made is sound like computational photography in phones was something ground breaking and never before seen. Its been in the Pixel phone for years.

That has nothing to do with a shortage of engineers. There are plenty of engineers, just none that are willing to work for 70k a year.

There is a salary divide between what big companies can pay, and what little companies can pay. That's drawing a significant portion of the talent away from the smaller labor market.

Either the smaller companies need to consider hiring more junior engineers (of which there are plenty). Or they need to make their offers more attractive.

If the article had a title of, "Ada is a great language for embedded", then great. But it's implying that Ada is the only language that exists today that can accomplish this task, and that's just not true. Rust is merely one example, and the best I know. And the tooling of these modern languages perhaps are better reasons to use them than Ada.

But yes, perhaps I was too critical, it's mainly the title that is a little misleading, and then the content didn't express anything specific about Ada that other languages don't also have.
