It's a bit like red wine, every week there's a new study proving the opposite of what the previous study said.
Is not like newer Lenovo's ThinkPads are much more upgradable than an M1 you know?
I’m a bit confused how you’ve taken the “shocking” part so extremely out of its immediately adjacent context.

“This is assuming that a person *without any media exposure* at all would still find the homeless situation shocking”

How could a hypothetical person without any media exposure at all be informed by the extensive media coverage?
Viral Instagram photographer has a confession: His photos are AI-generated
I'm in the same boat, I just got on it earlier.

My first Mac was a mid-2012 MBP. I loved it, and it lasted until my then-two-year-old poured a glass of milk into the keyboard in 2016. I used various Windows machines for a while, then bought a new MBP in 2018. I had that one for less than a year because I realized I just wasn't using it much - I always had laptops issued to me for work, and a Linux box on Linode that I could SSH/RDP into.

When the M1 came out I bought a 14" MBP. It's only got 8GB of RAM, but it's faster in actual usage for anything but graphics-heavy gaming than my (admittedly, aging) gaming desktop.

I used to be fine programming in Windows, and that was before WSL/WSL2. These days the experience is much better but it's still easier just to dual boot or SSH/RDP.

macOS, OTOH, has gotten a ton better in that time. There are a few nagging things I don't like but it generally just stays out of my way and lets me treat it like a Linux box with a nice, relatively consistent WM.

I still have my Windows desktop because it's better suited for gaming and has better support. If not for that I'd be full macOS.
> On HN I trust someone who's inviting nit-picking by saying "this is SOP, google it your damn self" a lot more than I trust someone citing their sources [...]

There's the old "trust but verify" saying that's relevant here. The person that cited their sources at least did some of that work for you, whereas the other person might have based their claim on random shit they overheard on the subway.

I don't understand this idea that showing less of your work is somehow more convincing.
I thought it had to do with coil whine.
Texas is planning to make a public investment in space
it's not safe.
I’d start one as soon as possible. Even an audience of 10 people is better than an audience of 0 people.

Secondly, I’d explore more channels rather than Twitter. Reddit, HN, and even Facebook Groups (yep, there are still people using those).

Third, I’d look deep into my network to see if there was anyone that could amplify the message. I’d ask every single friend I have and beg them to share. Even 1 RT could make a difference.
The battery life (and in some cases, horrifically bad TN panel screens) are what kills these older ThinkPads, Latitudes, etc for daily drivers. If I’m spending so much time at my desk that being tethered doesn’t matter I’d be better off building a desktop with modern hardware, which confers the biggest benefits of ThinkPads while also being vastly more powerful and expandable. If space is an issue, ITX builds solve that pretty neatly.

Really, somebody needs to develop power-sipping ARM motherboard board replacements (much as xyte.ch does with x86) for the various business notebook models.
I strongly prefer to get all of my activities out of the way as early as possible. I have ADHD and a looming afternoon activity locks me into place and I cannot be productive until that afternoon activity is set to start. Its a curse.
Maybe because those who are trying to diet are already obese?
> TikTok says it will ensure that ads are placed in front of users who are “truly paying attention” and that brands will only pay for ads if a user has “voluntarily” watched it for at least six seconds, or has interacted with it within the first six seconds.

So that's interesting. What are advertisers going to do to lure me into watching ads for longer than 6 seconds? Tiktok makes it extremely easy to flip through videos instantly and I'll often (not always) judge I don't like a video in under two seconds.

> With this pay-if-they-engage feature, TikTok is making bold claims that are either dubious and unscientific or selling an invasion of privacy – or both. In claiming that ads will be delivered to “emotionally” and “tangibly” engaged users, TikTok is suggesting it could read people’s emotions. However, it fails to provide details on how the feature would actually work. To date the only technologies that purport to gather such precise, highly sensitive data are what are called “emotion recognition” technologies.

> Experts have repeatedly criticized “emotion recognition” as unverified pseudo-science that, even if it were possible, would result in highly intrusive forms of surveillance. Yet, TikTok has commissioned various projects on emotion recognition, even delving into contentious neurotechnology / neuromarketing approaches. For instance, TikTok conducted a study in partnership with MediaScience which creepily resembles what Focused View claims to be able to do.

I have fun with Tiktok but it will never get camera, microphone, or contacts access on my iPhone.

Could it be measuring the gesture used to swipe? Angry swipes might be different than non-angry swipes, for example.
"So long as you are awake enough to be safe and aim at the target, you can shoot a gun."

Please do some research into a topic before spewing complete nonsense. Competitive shooting and marksmanship involve a lot of different things. Adequate sleep and being focused/alert are some of the core components to good marksmanship.
Yet another extension of what Zuckerberg unleashed.
I don't know what there is to disagree with. Softbank did exactly what the tweets say a16z did/is doing, except 5 years ago. Except Softbank is 10x larger in size. They have already suffered a huge loss, except they are dripping in debt, and there's still plenty more for Softbank to fall. 5 years ago Softbank was considered a Tier 1 company as well. They are now what the tweets believe a16z will become in a few years. The final stage will be liquidation of their positions to pay off debt, which will critically injure Silicon Valley for years.
Conspiracy Theorists Are Coming for the 15-Minute City
> I experienced a deep realisation that our thoughts manifest from nowhere and not from ourselves (words fail me here) and that the construct of 'me' was completely false and was just a reverberation of my environment. I understood there was no me.

A way to frame such an experience (a version of which I've had too) is to say that we realize that the purpose we've been having for our striving is bogus. e.g. There's no special "me" that's important to make look good, that needs respect and fame etc.

But that doesn't mean we lose all striving. We just find a new, more wholesome, purpose for it.

I think Eckhart Tolle talks about this. There are other perspectives, too, that one can garner by reading philosophy. (e.g. Aristotle's Nicomachean Ethics, which puts virtue as most worth striving for; there're also much simpler takes on what's worth striving for in an ego-less sense, which are paradoxically harder to intellectually grok while being much more commonly espoused in practice, such as love for home, and family).
Those are close to the same thing, though. _Obviously_ there exist people outside a family who are more qualified for any given thing than any of the people in the family.
Earlier, on HN I read that it improves lifespan and now it is associated with early death.
Am I wrong to have suspicions about the possibility that food conglomerates may have funded this study? I am not a conspiracy theorist, but with the number of dietary science that turned out to be wrong over time, I must be skeptical about every new study.

I’ve learned about Long Covid after Dianna Cowern aka The Physics Girl started mentioning on her Twitter (https://twitter.com/thephysicsgirl) that she has it. Unfortunately she had to be admitted to ER recently due to it. In the comments to her posts I’ve seen a lot of folks from the US recommending doctors specializing in long covid. Hope you recover soon! This disease is awful.

It surprises people that the US had, relatively speaking, more copyright hoops for creators to jump through than most of the rest of the world prior to harmonizing with the Berne Convention.

Only once that can be done cheaply. Which so far is not the case.

Basically electric cars are cheaper to drive than cars burning fossil fuels which in turn are cheaper to drive than cars burning synthetic fuels.

As prices of things like batteries and renewables come down. Synthetic fuels might become cheaper than fossil fuels since you typically need lots of energy for producing synthetic fuels. If the amount of energy gets low enough it might get close enough to simply charging a battery with the energy and using it. But we're a very long way from that.
The key word is "If". Since we don't generally read other peoples code, we tend to rewrite the whole damn thing every 10-15 years (sometimes 4 years).

The reality is it all comes down to testing. If S1.0 has a unit test that says "Person should not get financial help", S2.0 should also have a unit test that says "Person should not get financial help", and work the same.

Of course my unit test name is designed to enrage, but let's be honest, we're writing code that makes these decisions.
I used to work for an industrial automation company, building custom-designed computers (the entire system, including the motherboard) that control manufacturing lines. The units we used to design, being field upgradeable, were far less reliable than the units where the memory and CPU were soldered to the motherboard. That wasn't an option for mass storage at the time. Vibration and heat do amazing things to components that are removable. Also, components that are soldered on the mainboard, by not using a socket, generate less heat. The interconnect can also be faster. So yes, upgradeability does tend to decrease reliability. By the time I left that company they had switched to entirely non-upgradeable units because they were far more reliable.
2012 MBP was indeed my final reliable Apple product. I "upgraded" away from it unfortunately (because jobs always paid for these things) which resulted in me throwing away at least 3 newer models, which simply stopped working. I'm gladly off Apple for 2 years now!
That seems like a security issue if podman can do that without root access, yes?

As in -- on a multi-user machine, this could be a problem.
> The quality of the code is irrelevant,

Until it needs to be maintained, or has weird bugs.

> As long as the output gives you what you need, the code quality ultimately is an efficiency play. But as AI coding improves, it can refactor itself, so it's a short-term problem.

Not sure how this is going to work on large codebases.
It's definitely relevant. Some upper caste individuals, from my personal experience, tend to expect things to be done for them by others. It doesn't matter what position the other person holds, the only thing that matters is the authority given by caste
That was beautifully said.
They claiming a statistically significant hazard ratio within 1-6 years of a single survey response, that covers only the previous 24 hours? No other factors considered?

This doesn't pass the smell test.
it is though?

Compare the Teams app vs running Teams on Edge in the web. Big difference.
Don't a lot of drug addicts only eat once a day?

And what about obese people eating three big meals a day?

I feel great when I stop eating by 2 PM. Sleep better, have more vivid dreams, and more energy the next day.

I'm reminded of an old doctor approaching retirement who told me longevity was largely luck and genetics.
I must have expressed myself incorrectly. Generating coding problems automatically with ChatGPT doesn't mean you just throw whatever to the candidates. You can both auto generate AND curate. The part I'm against it is manually creating problems.

There are several reasons for this. One of the biggest problems with FAANG interviewing is that questions get leaked almost instantly. I spent days creating a brand new original problem, and it got leaked by the second time I asked it. ChatGPT gives you a unique problem for each candidate.

There is also the angle of leaning in the tech. I would encourage candidates to use any means to review the code as they would in the workplace, including IDE, web search, and LLMs. If these tools are going to revolutionize the way we work, I want to see how well people can use them.

Lastly I'm also intrigued by the dynamics of this kind of interview. As an interviewer I have asked the same question 50 times and I have seen all variations of answers. But what if the problem is relatively new to me? This seems closer to a pair programming exercise with two colleagues working together to solve a problem.
> maintain secure communications that can't be tapped by the authorities

That's...interesting. Which authorities can't tap them? The cartel ones, the local gov, the feds, the feds' consultants from other places, or the technical authorities who know how this gear works?
I get that in other software stacks you might want to avoid mocks and stubs due to friction, but in JavaScript what's the big deal? Mocks are easy– just do it.

His 4th point in the conclusion at the end:

> I wanted a cheap travel laptop I could replace without blinking an eye at the price.

It's pretty easy to get ~10 years out of a good laptop from Apple. I'll be shocked if this guy is still using his Thinkpad in 10 years, and even if he does, that he didn't create more e-waste by swapping parts that he wouldn't have had to sticking with the MacBook.
Yeah, it's still best in class I think; I just bought a new Mazda and did some comparison test driving, and although I'm not as happy with it as the 2016 offering, the 2021 design is still great.

This is the 2016 climate control cluster I preferred: https://cdn.shopify.com/s/files/1/1225/1056/products/317144_...

What was nice about it was the three dials for all controls.

This is what they have now:

https://cars.usnews.com/pics/size/776x517/images/Auto/izmo/i...

I think this is aesthetically better, but they turned the fan speed and vent settings into push buttons instead of dials. Whereas before I could set this without looking, now I often have to look to verify my settings. So in that sense, I wasn't happy about that change.
100 lines of poorly written code (by AI or humans) added to a 1M line codebase is easy to spot and fix by the dedicated humans who have that whole system mapped out in their heads.

Having AI write a 90% accurate 1M line (or "parameter") codebase all at once, (which seems to be the expectation here), is the "risk" you're overlooking. No human will be able to know where to start debugging that. At least not yet. But will yet come before incredibly dangerous amounts of AI written code is pushed into critical systems everywhere, by naively optimi$tic opportuni$t$?
Old Apple laptops, like the 2012 mentioned, yes. Newer ones don't really last long anymore.
Raspberry Pi device could let you create a private 5G network on the go
I think a legitimate criticism of this article is using the clickbait "Software 2.0" label for something that's – as very well described by the same article – so very different from "Software 1.0." Considering ALL software, the intersection of uses cases where Software 1.0 and Software 2.0 truly compete are a very narrow niche. In the real world Software 2.0 will thrive in the next decades but Software 1.0 will be there just as much as it is today.
If you make all your code as pure function, then testing is easy.

First thing to do: Stop using class. Ask yourself first: Should i use a class here and there ?

Wait, i miss something here: Writing pure functions is hard ?
Between sea levels rising and the risks of tsunamis, I certainly would not want to live anywhere near the coast. It’s a nice place to visit though.
> TikTok is suggesting it could read people’s emotions

I assume that isn’t too hard for a company which has a big and well labeled dataset? I’m pretty confident that Spotify knows exactly when I’m sad, because at those times I like to listen to very certain music. I’m also sure that Google has the same capabilities (and is probably implicitly using them already, as their ad model automatically tests the ad’s performance across different groups?)
Performance didn't have any influence on section selection at my colleges. Is that normal somewhere else?
Ask HN: PDF reader for reading journal articles on mobile?
I mostly browse the internet on my phone, and have no trouble reading most content. The biggest exception is pdfs, in particular of journal articles. Obviously pdfs are intentionally constrained to display text is a certain way, and when it's optimized for an letter size page it's hard to work with on a phone. I either have to pan back and forth or try turning the phone landscape wise and viewing the page at full width. Has anyone found a tool that makes it easier to view pdfs on the phone? It seems like it would be a common use case.
The "correctness" of neural networks is a vasy field of active research, with many prominent minds in deep learning as well as traditional CS theory working on it. We have many results for small scale networks, but I don't know of any results that can "prove" the correctness of an image classifier, for example. After some point, the correctness of such methods becomes very ill-defined, since unlike the normal programming world where everything is mostly in binary, here you will have to answer questions with some variation of "this is 98% likely" with no scope for 100% certainity.
Because code is faster and more correct than a neural net if written reasonably. With code you don't need several gpus to calculate a sum of several million records in database.
if you have some kind of evidence to believe that, you wouldn't be wrong. But without that evidence, yes, you'd be wrong to have suspicions just based on disagreeing with the result.
Not always. People thought Facebook had an insane seed valuation. Google was “very expensive” upon IPO.
Overall, my productivity & creativity looks like a gently downsloping graph throughout the day. There are some dips and surges, but in general that is the trend. Three hours first thing in the morning is significantly more valuable -- I prioritize my work/side/personal life so that on any given day I make sure I stack the important stuff earlier if I can.

Our neighbors are the 7pm family. They own their own business and they're out the door at the crack of dawn to tend to things. The kids have always gone to bed at 7pm, except the teenager of course. So such families do exist, but I think it's important that the whole family be on the same schedule, for the reasons you mention.
At least you have keyboard shortcuts. On macos you don’t get anything that isn’t a menu item.
I doubt it deters people who are just going to grab it anyway.
I have a large investment in Meta and Snap in anticipation of TikTok getting banned in 2023.
Better still - I upgraded my gaming desktop with a new CPU the day Microsoft messed up the upgrade detection for Windows 11. The first time I booted it with the new CPU it showed me the "Upgrade to Windows 11" screen for the first time. I though "Oh, cool, my CPU must have been the bottleneck. Sure, go for it."

Turns out, it was just coincidental timing and my desktop lacks TPM. It's still running Windows 11 and I've not run into any issues, but AFAIK I won't be able to re-install it if I ever format the drive.
It doesn't know it's happy or not ?
Ah makes sense! I’m no expert.
Supreme Court rejects appeal of man arrested for Facebook police parody
Likely this is because people who are dieting are overweight. This is looking at damaged people and then drawing a conclusion. Pretty good chance these people would have died similar deaths regardless of diet. Better study would compare them to a control group to determine if risk went down or if life expectancy went up.
> In what way is even our modern scientific secularism not ultimately the same kind of faith that the author thinks is "dumb"?

That is the correct answer! How will you refute it?

Oh. Big disappointment: you have no refutation, just a lot of insults.

I refuse to download TikT0k. I won't even use the web app version. It fingerprints your browser, which should be a banned practice, but they get away with it and have no accountability. YouTube has ripped TikT0k 'best of TikT0k' videos so I'm not missing out really.
The vast majority of what people do is this, yes. Just like how most of the time, we're all running on autopilot and our behaviors are pretty much just following scripts. "Meat robots".

But it's not 100%.

It really is.

These ICOs were essentially considered "free money". Mint a coin, put some power behind it, profit.

This isn't a business, it's a get rich quick scheme.
Not the same thing... Also there can't be scientific evidence that anything improves lifespan.
“Among participant with three meals per day, a meal interval of ≤4.5 hours in two adjacent meals was associated with higher all-cause mortality.” So people who ate three meals a day ALSO fared poorly? Am I reading that right?
Can someone interpret the Hazard Ratios for me? What is a HR of 1.3 or 1.8 actually saying?
All software is riddled with errors and for most purposes that's fine. Any developer, stakeholder, whatever, who thinks otherwise is living in a parallel universe.

It may be possible in the future to have "for all practical purposes flawless" software, which might make sense for select special applications. That would be a new thing though, rather than something we have and could lose due to adopting AI development.
Thanks I've been debating this. 8GB just feels wrong but I hate to pay that Apple upgrade premium.
Frequent changes mean his shit doesn't work.
This is not a study about "intermittent fasting", it is about people who skip meals. I don't know why they skip meals, they don't know why they skip meals, but I would not assume these are all super health conscious people engaging in deliberate intermittent fasting.
Yeah, but take all of those with huge grains of salt. Some of them will only run the vendor’s custom kernel, others have library/driver incompatibility issues, the non-Pi SBC ecosystem is a bit of a crapshoot. And I say that as someone whose primary non-Pi experience is with the fairly well-supported Jetson Nano. You quickly realize why Raspberry Pi is so beloved.
> I don't know of one that can do 20% of what AWS can do.

We only use a few AWS products: Route53, EC2, VPC, EBS, and S3/Glacier. This feels like <20% of what AWS can do today.

Are these use cases not yet covered? I'd be OK with Route53 not being in the box, but surely we have VMs, storage and backups sorted by now, right?
Most technological advances haven't been explicitly for the purpose of collecting information about the gullible, addicted masses. Nor have they been easier to avoid.
This seems at odds with the numerous studies on longevity and caloric intake being strongly correlated.
