Sorry for the delayed response.

It has allowed me to work on some very cool robotics, and IoT projects. I've been able to learn a ton in the process about how computers work. Things like having to learn about how our FreeRTOS scheduler works, have been a fun process and provide some insight (albeit not 1:1) on how larger scale OS's work.

I feel like it's also made me a better programmer on the higher level stuff too. Hard to explain why though. It's not the kind of thing that makes obvious sense. It's not like knowing how to efficiently pack bytes into a struct, somehow helps you be a better Scala or iOS developer. That's just not the case. Rather, there's something about knowing the low-level stuff that just eases my mind when it comes to writing higher level code. I've always been the type of person that gets distracted by needing to know the deeper layer of how something works.

Even in undergraduate classes like biology, I needed to know HOW that mitochondria ACTUALLY handles metabolism. That's what I mean when I say that the lower level stuff "eases my mind". I can call a higher level function, or use some higher level framework, with a clear understanding of how it could (and probably) is implemented. That makes me a better developer, because I can stop asking questions and start making things.
When can get .myname for $35/year I will be happy with Amazon having .amazon.

Seriously why don't the ISPs of the world just collude and reprogram all DNS servers to equate .x to .x.com or some arbitrary consencus-chosen TLD to spite these corporations' displays of power, and make it meaningless/impossible to own .x? People can then go to http://news.ycombinator/ if they wish, and then Y-Combinator can go ha-ha at Amazon for their shenanigans.
amp-analytics is disabled in AMP for email now, but it seems likely they would enable it in the future. This would mean that clicks that don't load a new page but expand an accordion, jump to a part of the page, or switch to a new tab, could be tracked, and conceivably it could be linked to a user account.

So, at the moment, AMP for email is similar to regular HTML emails, but AMP lays the groundwork for more in-depth snooping into reading of emails.

I remember the days of hiding text in the same color font as the background so that grepping would make your page the top result.

A simple "-site:somesite.com" removes those, or just scroll past them. Keyword spam is easy to ignore because the title of the page, the domain, or the path often has nothing to do with what you're searching for, and the preview text is nonsensical.

The dumber search is, the easier it is for the bad actors to game it and drown out the legit sources.

The dumber search is, the easier it is for users to ignore the crap and find what they're looking for, even if it's not the first result. The "smart" omission of results has the effect of removing a lot of useful ones too. Google's claims that they have X number of results for a search is essentially meaningless if you can't actually see them all.
This hints at a common sentiment I see on HN. The idea that everything you and I buy and do is very considered and intelligent. But the great unwashed masses don't put such thought into their purchases, and are being "duped" by evil conspiratorial marketing. If only everybody else was as smart as us, right?

Have you considered that maybe the majority of successful companies in the world are fulfilling customer wants and needs and thus making what you call Pareto improvements? And maybe it's just that the other "dumb people" derive joy from different stuff?

The market sorts these things out. It is mostly efficient. Not perfectly. But mostly. A company that is providing net-negative value to the world is a short-lived company.

I've noticed the same with song lyrics when I try to find a particular song I've heard somewhere. Hundreds of results of the same handful of "top" pop music industry artists but anything alternative is hard to find, even if the search query very clearly is not a good match for those popular results. I know the stuff I'm look for is out there, but it just won't show up.

I've switched to Firefox over the last few weeks. It definitely feels faster on my desktop PC which runs Linux, also no problem in Windows when dual-booted.

Though there are two big issues imo:

- When running Firefox on my late 2013 Macbook Pro, it doesn't feel as fast as Chrome or Safari, it feels very sluggish. I am forced to use h264ify to force YouTube to use h264 instead of VP8/9 as it makes my Macbook Pro turn into a steam engine. Besides the fact that this is Google's fault and its "monopoly?", it all around just feels slower elsewhere as well and it takes more power compared to even Chrome it seems to me.

- Lastly it does not sync all of my settings that I want. Why does it not do that? I run Firefox on Linux, MacOS, and Windows and I have to change my settings everywhere every time I make a change and it's a pita. Google Chrome just syncs all of my settings across all of my devices except for extension settings (which is a bummer).
I've been thinking about this some recently. Is some scheme like the following remotely plausible?

- Have a piece of hardware in-frame that can show hashes that is hooked to the operating cameras.

- In each frame show the hash of the previous frame (low latency would be required, as would the transmission of the full-quality original).

- Publish the original seed and the final hash (and, since the original is broadcast, the whole chain of hashes can be verified).
This is not about hosting an LTE 'access point'. It's about creating a access point which uses an LTE uplink. I agree, the title is somewhat misleading.
There is no adblock thing. Chrome isn't disabling adblockers. They are changing the API to speed it up and extension developers are whining because they have to make some changes which will give users better performance.
Interoperable instant messenging too... and generally being able to move data from one application to another.
If you put in an exact model then I suspect the results will be very different.

The other infuriating thing that's related is if you're trying to find a schematic or service manual, Google thinks you're just looking for the (often useless) user manual. Searching for the user manual does not make it think you're looking for the service manual... it's absolutely idiotic, because who would search for "service manual" but actually want a user manual? Beyond some weird conspiracy theory involving anti-right-to-repair, I can't explain why.
> Besides the number of ips what are the advantages?

That is the primary advantage ... or rather all the consequences of having globally unique addresses for everything available with minimal administrative overhead.

> ipv6 vs ipv4 Which one is better for privacy?

Rarely makes a difference (web tracking happens via cookies anyway), and IPv6 has a huge potential of enabling less centralized protocols.

> Which one is better for security?

IPv6, because one flat address space without translators is easier to reason about and doesn't need so many workarounds to make connections work.

> Which one is better for speed?

According to what large content companies publish, IPv6 is usually quite a bit faster (lower latency), rarely slightly slower.

> Which is easier to configure?

IPv6

> Which is better for end user?

Directly? Doesn't really matter. Indirectly? IPv6.

> Which is better for advanced user / net admin?

IPv6 hands down.

> Which is better for companies?

IPv6, unless you have to deal with legacy software that doesn't want to speak IPv6.
Thank you. I was hoping for a more definitive answer, may be a reference to an explicit test involving memory dump analysis.
Would you have needed fast home internet without the web being popular though? Granted, they didn't look as good, but I know plenty of sites that loaded more quickly 15 years ago when my internet speed was less than a percent of what it is now.

Of course, the past is always rosy, especially when you were young, and new things are always exciting and lose their novelty when you get used to them, but I found the internet much more interesting back then.
Like all such quotations which are taken out of their natural context (and even their wording is altered), it all depends on many factors. For instance, whether or not the choice comes down to only these two options, whether there is a prominent hierarchy of power at play, is the cost of being a maverick among the conformists majority a justified one, etc.

But if a person has their ego and individualism in check and trust their instinct to be in benefit of their larger group and their goal, then sure it is justified to proceed now and ask for forgiveness later.

That's not true according to the latest IPCC report, which estimates "equilibrium climate sensitivity" to a doubling of CO2 (which hasn't happened so far) to be between 1.5 and 4.5 degrees C.

Incidentally, the 1.5 to 4.5 degree C uncertainty range is unchanged for decades, illustrating the lack of progress in this field of science.

Why this article is upvoted is very odd. The article does bring up an interesting topic, there are issues with the incentives SEO places. Just like the incentives that directories placed, anyone remember AAAA Plumbing Services? Or before that, with paying writers per word/line (I'm looking at you books from the 1800s)

Aligning incentives is hard. And it's interesting. But the arrogance of the person who wrote the article is amazing, not to mention the cognitive dissonance he must experience. I personally couldn't get over that to really appreciate the larger topic being covered.

The weakness of GPUs is that the minimum amount of work is incredibly high for acceleration to make sense. If you have a batch with less than 10000 units of work then you shouldn't even think of writing a GPU kernel. GPUs will never used for stream/network processing workloads because no one wants to wait for a buffer to fill up. A FPGA could in theory offer the same throughput but with a much lower latency.
I’m also not fully satisfied with Safari (poor control over privacy — content blocking is weaker than uBlock Origin, and you can’t disable cookies and javascript on a per-site basis).

Wouldn't the router only have a route for 192.168.0.x or whatever to go to the private interface? Why would a packet still addressed to the public IP get routed to the private network interface?

So how would you address a device on the private network from outside?

edit: I read your other response. Fair enough, if your ISP is sending you privately addressed packets they could get through.
The Weekly Review: A Productivity Ritual to Get More Done
No, there are none. Not a single operational long-term storage facility for highly radioactive waste.

The US plan is Yukka Mountain (https://en.wikipedia.org/wiki/Yucca_Mountain_nuclear_waste_r...) proposed in 1987 and not yet open.

Germany has a similar story with Gorleben (https://en.wikipedia.org/wiki/Gorleben_salt_dome), which was proposed in 1973 and also isn't actually operational. The prototype, also in an old salt mine, nicely showed how difficult these projects actually are when brine flooded the storage area, corroded the containers, and mixed with the contained polonium, cesium, etc.

Read https://en.wikipedia.org/wiki/High-level_radioactive_waste_m... for the full overview. It's full of great sentences like:

> Governments around the world are considering a range of waste management and disposal options, although there has been limited progress toward implementing long-term waste management solutions

Won't work: SEOs already send user signals by literally paying normal, average persons to once in a while do a search for something and click on each result until they arrive at example.tld.

The thinking is that Google tracks keywords + clicks, and if people search for "keyword" and aren't satisfied with the info on domain1, domain2 and domain3 (demonstrated by clicking on the next result) but are satisfied after visiting example.tld (demonstrated by not clicking on any other results), Google will rank example.tld higher.

It's not cheap, and I consider it to be more Voodoo than proven fact, and most SEO people are generally more the religious type than the scientist, so they won't run tests. They do it, see that they rank well and continue to do it. I've suggested sacrificing chickens, but nobody listens to me (or they won't admit that they do).
Yes, I’m saying the timing is not the best because this one was serious and is still fresh; if you’re already discontent with Firefox, articles trying to convince you to switch won’t do the job, right now.
Correct. If you were to create an actual “access point” you will have the FCC and other agencies knocking on your door within minutes.
I don't think there's a need for an amp cache with amp4email. The privacy concerns that make an amp cache necessary don't apply in the same way, only the security concerns that require a safe html subset. So an imap client could cache the amp js locally, and render dynamic content by querying the sender directly.

I could be wrong though, but I believe that works.

> You can link the exact same intrinsics in a rust binary to get the same intrinsics.

Intrinsics are not library functions. You don’t link them anywhere. They’re processed by compiler not linker, and for SIMD math, each one usually becomes a single instruction. Linked functions are too slow for that.

> This is nothing about rust or not.

When I code C and write y=_mm_rsqrt_ps(x) I know I’ll get my rsqrtps instruction. When I write y=_mm_div_ps(_mm_set1_ps(1), _mm_sqrt_ps(x)) I know I’ll get slower more precise version. I don’t want compiler to choose one for me while converting a formula into machine code.
Ask HN: Do you ever regret having kids?
For the HN users who have kids, do you ever regret having them?

I saw this article and was wondering what you think about it?

I have two kids and a wife. Love the kids but sometimes feel resentment that I got married young and cannot pursue some of my other interests, like entrepreneurship for example. Wife's looks have also faded and the rare intimacy just compounds this feeling.

Would like to hear different perspectives.
They don't need to support it. It's the exact same linking process as from a c binary.
I guess it's explained elsewhere here aswell, but the "lazy IO" discussed is pretty much a bug: you read a file to String, but this String is loaded from the lazily while you consume it. But the problem is: you already get the String thinking all is well, but if something happens to the file handle you get a runtime error. This shouldn't happen with pure values.
Our real problem with the use of gasoline isn't really how much of it we use but rather how we use it so inefficiently, which of course leads to more usage and related pollution than necessary. IIRC, gasoline vehicles are only 20% or so efficient, while diesel vehicles are a bit better. And contrary to what you say, if we move more towards electric vehicles in a big way then I could foresee a day when we instead burn gasoline or some other fossil fuel equivalent in a more centralized and much more efficient manner, much like we do with natural gas today, and then use the electricity generated by that to power cars.

As to the PM 2.5 thing, like I said a lot of that gets oxidized to CO2 anyway, which adds up over time. Lately the EPA has been making a lot of noises about regulating this stuff, except that it turns out that much of it comes from places like our own kitchens. And nobody really wants the EPA involved with that part of it, hence the efforts to reign them in somewhat. But of course any talk of potentially restraining the EPA here is personified as "evil" in the press.
