I don't think we know the entirety of what happens in the skin with UV exposure. We are pretty sure that vitamin D is good, and that cancer is bad, and that seems to be all that people talk about, but there are a lot more things happening that we don't fully understand.

I suspect when we know more, the best answer is going to be moderation. But it's really anybody's guess right now.

I agree in theory, but doing so would have been very difficult practically. The IPv4 header structure is very rigid, and it wouldn't have been possible to just add more bits to the src/dst fields without breaking things.
The only reasonable route I've seen would have been to add an "area code" or "country code" to the Options fields and have huge border routers to translate packets between different locales. It would have solved one problem, only by creating an arguably much worse one.

Every of the lightning talks itself had about 20 short different topics,
And as I wrote these were examples, you didn't expect someone to re-enumerate them here all to refute your statement. You can easily find them yourself.
Have look at this page, where others listed their favorites, there are many more.
But I don't think from your reply you didn't look at the list of sessions yourself.

I agree with you and the other posters actually, but I think the efficiency compared with typed work is the reason it’s having such a slow adoption. Another thing to remember is that there is always a mild Jevons paradox at play; while it's true that it was possible in previous centuries, teacher expectations have also increased which has straining the amount of time they would have grading handwritten work.

I agree on both points; government work can involve very little real work with no real stress of being fired. Similarly, doing meaningless work will destroy your soul and will make you hate your time in the office even more. I'd even go so far as to say caring deeply about your profession is a western value, and trying to work as little as possible is going to be difficult in a western country

The most outrageous anti-Indian sentiments I ever heard came out of the mouths of other, very slightly different Indian immigrants. So I doubt "Indian" is a monolithic identity. This is, of course, by no means specific to India. The vitriol that my Vietnamese in-laws reserve for Vietnamese who were born 30km from where they were born is incredible.

Yep. There are plenty of small manufacturing companies that have embedded programming projects that aren't sexy or cutting edge, but are just little STM32 or similar chips running bare metal no-OS code for all kinds of simple little devices for different industries. I've been doing that work for the past twenty years. It scratches my engineering itch, but also lets me work pretty independently, put in my mostly stress free 40 hours a week, and then go home and not think about it.

They are considered radioactive by their primary target audience in the US, have been surpassed in various ways outside the US, seem to be focused on a few boondoggles internally rather than fixing what is broken in their core business, and their CEO has been distracted by other ventures.

I expect this decline to continue indefinitely. I also wonder when the stock price will reflect the company's past and projected results.

I tend to be conservative with my estimates, because a very large fraction of web traffic comes from bots and crawlers with no human involved. That is a bit unfortunate, really. I know there are 'proof of work' schemes to mitigate this but I don't like to introduce artificial complexity to my website, unless I really have to.

When I talk about visitors arriving at my website from RSS feeds, I am not counting requests from feed aggregators or readers identified by their 'User-Agent' strings. Those are just software tools fetching the feed. I'm not talking about them. What I am referring to are visits to HTML pages on my website where the 'Referer' header indicates that the client came from an RSS aggregator service or feed reader.

It is entirely possible that many more people read my posts directly in their feed readers without ever visiting my site, and I will never be aware of them, as it should be. For the subset of readers who do click through from their feed reader and land on my website, those visits are recorded in my web server logs. My conclusions are based on that data.

It's not for me, but:

- Google is an American company

- GrapheneOS Pixel support depends on Google's Pixel support (and has been affected by Google's decision to open-source less of their Pixel trees)

- This OS promises to maintain the usable app store + cloud experience

- OS maintenance isn't dependent on a bunch of volunteers/donations

- You can just buy this from an official reseller rather than making your own or having a sketchy website pre-install a custom ROM for you.

I think GrapheneOS has the better developers when it comes to privacy and security, but there are reasons to go for the reliability of a corporate entity you pay for support over hacking together an alternative.

No it's still my network that I'm on. I don't have to be a good neighbor because I also own all the adjacent hardware.

There's already a body of laws that incentivize against violating copyright. It lunacy to stack on additional ones in service of the same goal. That's like saying that it's both illegal to speed, and it's also illegal to tell your friends that you'll be there in 15 minutes when you'd have to speed to get there sooner than 20, whether or not you actually do the speeding.

Devices are not legal persons, they can't sign contracts on your behalf, nor can they commit fraud on your behalf. If a bogus is attestation is necessary in service of interoperability, that's a technical detail not a legal one. If what you want is copyright enforcement, focus on the crime not the circumstance under which a such a crime is possible.

I would aim... Away from the glare of the software world.

There are plenty of smallish companies that just bob along. If you pinch your nose for long enough you quickly become indispensable, and your productivity will rarely be very challenged.

But... Be aware. "Bullshit jobs" can be enjoyed only by the right mind. Most people find them miserable anyway, it doesn't really matter if they are easy, or low effort.
(This means also that I disagree with recommending to become Project or Product Manager - when those roles are properly useless... They are also soul crushing, with layers of stress on top)

I had one of these. Comfortable income; not big tech but well over USA median. Remote. Put in 5-15 hours a week.

Strongly recommend against it.

What I would recommend instead is have a hard look at what's causing pain in your current situation. Try and get as concrete as possible. Try going one level deeper from 'world is hyper capitalistic' to what hurts. When I talk to people that express similar views there is usually some other deep hurt that is going unaddressed. ie 'im not being valued for my work', 'I have a deep fear I will not be able to provide or be valued', 'I like tech, but the current structure of tech employers doesnt fit well with me(weird noises in offices are deeply uncomfortable)' etc.

It's almost counterintuitive but 60 hard hours / week at something you enjoy and thrive in will be easier and feel like 5 hours at something you hate. Most everyone has a desire to feel valued and needed, so look for what that can be for you. Note prestige of impact != internal satisfaction. If you enjoy serving tea, then doing that for little money (and lots of time) will feel better in the long run than doing a few hours of tech work you despise.

Also... strongly recommend tuning out from the internet / news / social media. Sensationalist headlines can obscure our felt experience of life.

Reading between the lines of your post, Im not sure if what you want is a job with low hours or to solve your deep unhappiness? If I told you I had a job that paid well but you would still be happy would you take it?

It's funny back in the Google Reader days monetizing via RSS was quite common. You'd publish the truncated version to RSS and force someone to visit the site for the whole version, usually just in exchange for ad views. Honestly while it wasn't the greatest use of RSS it was better than most paid blogs today being ad-wall pop-up pay-gate nightmares of UX.

"Details on how you get an IP and what it looks like changed but..."

This is exactly what I'm talking about. When you have problems with your IP network, that's the first thing you try and figure out, "what's my address? Why is that my address? Did it change? If so, why? Are other devices able to get packets? What are their addresses? Why can those addresses get packets but this address can't?"

I recently passed the CCNA again and they really spend a lot more time on IPv6 compared to 15 years ago. It inspired me to go go all in this time and configured my home network with a PD allocation from my ISP. I also came up with some fun labs and even got a IPv6 sage T-shirt from Hurricane Electric.

> I went on holiday with someone a few weeks ago who is toughing it out with a no-Whatsapp dumbphone. He missed the train home because he got locked out of the holiday cottage and couldn't get in touch with anyone.

While WhatsApp is definitely the default messenger in many European countries, SMS and calling still exists and works on every phone. It'll cost you extra because of carrier shenanigans, but it's not like nobody has phone numbers anymore because of WhatsApp.

> Only the edge equipment would need to be IPv4+ aware.

"Only"? That's still the networking stack of every desktop, laptop, phone, printer, room presentation device, IoT thing-y. Also every firewall device. Then recompile every application to use the new data structures with more bits for addresses.

And let's not forget you have to update all the DNS code because A records are hardcoded to 32-bits, so you need a new record type, and a mechanism to deal with getting both long and short addresses in the replay (e.g., Happy Eyeballs). Then how do you deal with a service that only has a "IPv4+" address but application code that is only IPv4-plain?

Basically all the code and infrastructure that needed to be updated and deployed for IPv6 would have to be done for IPv4+.

> It's a strange mix of very good tech talks and left-wing extremism.

That last polarisation and othering is odd, unnecessary, divisive and not generally representative of 39c3 talks nor the CCC.

Antifascism is a long tradition among humanists and European hackers and not related to "left-wing extremism".

Why do you find it necessary to discredit the message of that talk? What's the supposedly extremist message in there?

You are not bypassing the router, the devices need to get their packets from somewhere, and it is only like a forever-open port if the router/firewall decides it is.

My ISP router supports IPv6 but blocks all incoming connections by default, which is kind of like what NAT does as a side effect.

It sounds like insanity because we tend to assume that no NAT means no firewall, because NAT has some firewall-like properties, and on the most basic networks, that's the only "firewall" there is. But none of the security features of "NAT as a firewall" are exclusive to IPv4, in fact, IPv6 has an advantage because the much larger address space makes a full scan practically impossible.

> there are likely too many students to maintain a high standard of education anyway.

Right on point. I find particularly striking how little is said about whether the best students achieve the best grades. Authors are even candid that different LLMs asses differently, but seem to conclude that LLMs converging after a few rounds of cross reviews indicate they are plausible so who cares. The apparences are safe.

It was not possible to make a "superset" of IPv4, if only because one of the early major blockers was that BSD Sockets suck by leaking low-level details of addressing so you'd have exactly the same argument of "why should I bother writing entire second copy of connection code in my application" for any superset you want to imagine.

Similarly, we have 30 years of experience that vendors will happily break optional headers or flags.

It seems like the industry is going to be forced to rediscover and implement capability based security models and process isolation by consumer demand.

It is impossible for the average user to reason about a different security model for each app, the only way for anyone to be confident about what a program is not doing is to move to a world where apps don't work by default, and a list of boxes need to be checked which enable network or file access and cause features to work.
Apple is the closest to the right answer here, but enabled-by-default and opt-out has to go away.

I tried using beads. There kept being merge conflicts and the agent just kept one or the other changes instead of merging it intelligently, killing any work I did on making tasks or resolving others. Still haven't seen how beads solves this problem... and it's also an unnecessary one. This should be a separate piece of it that doesn't rely on agent not funging up the merge.

This is the $1T question. What happens when Tesla finally gets valued as a car manufacturer, with side businesses in cheap but unreliable solar, and over-priced grid storage?

The self-driving car boondoggle has persisted for the better part of a decade, without a come-to-Jesus moment on the stock price. The pivot to robotics is clear fraud, yet retail stock investors are all to willing to keep the stock price high.

Musk has to lose a lot more reputation with the public before Tesla stock starts being valued based on the reality of Tesla.

Palm Treo/Pre and BlackBerry users! And probably Clicks users too. It's not a matter of "Does Russian language use the Latin script?" (it doesn't), but rather "What is the least annoying method to input Cyrillic on a BB-style keyboard, which doesn't have enough buttons for the йцукен layout?". Phonetic layouts such as яверты or яшерты were very popular for such devices back in the day.

I guess, it takes one, to know one. It's a long-standing belief of mine that those who expound the toughest lines, the harshest laws, and the strictest regulations are the same people that actually would make these laws necessary, if they had the opportunity. Curiously enough it often are the socially conservative "law & order" factions, so I am not surprised that the right-wingers are made from similiar cloth.

Of course, and to be fair, many of the ultra-rights do not even pretend, they say openly that they are against the rule of law. So nepotism, cronyism, and corruption are obviously on the table.

Yes, but not as much as you think.

A lot of silicon on a GPU is dedicated to upscaling and matrix multiply.

Ultimately GPU's main use is multimedia and graphics focused.

> On the down side they also help the extroverts and the confident, and you have to be careful about preventing a bias towards those.

This is true, but it is also why it is important to get an actual expert to proctor the exam. Having confidence is good and should be a plus, but if you are confident about a point that the examiner knows is completely incorrect, you may possibly put yourself in an inescapable hole, as it will be very difficult to ascertain that you actually know the other parts you were confident (much less unconfident) in.

If the buggy implementation relies indirectly on the assumption that 2^n - 1 is composite, by performing a calculation that's only valid for composite values on a prime value, there won't be a separate path for the failing case. If the Mersenne numbers don't affect flow control in a special way in either implementation, there's no reason for the path coverage heuristic to produce a case that distinguishes the implementations.

The problem is that the scheduled end of ipv4 was reached in 1990.

But attempts at providing replacement were stymied - IETF went not-invented-here finally getting v6, while USGOV went with CLNS, and meanwhile vendors hemmed and hewed to avoid spending any money on actually implementing changes and then allowed NAT availability to crush arguments and mandates.
by btilly | 2026-01-02 22:06:08+00:00
Current statistics are that a bit over 70% of websites are IPv4 only. A bit under 30% allow IPv6. IPv6 only websites are a rounding error.

Therefore if I'm on an IPv6 phone, odds are very good that my traffic winds up going over IPv4 internet at some point.

We're 30 years into the transition. We are still decades away from it being viable for servers to run IPv6 first. You pretty much have to do IPv4 on a server. IPv6 is an afterthought.

I forward emails to myself constantly (articles, videos, podcasts, random tasks), but my inbox quickly becomes a janky todo list that I never look at.

Built this with Claude Code over a few weekends:

1. Forward anything to save@itforlater.com

2. It auto-categorizes into read/watch/listen/do (uses Firecrawl + OpenAI to parse the content)

3. You get one daily digest with everything organized

No app to download. Just email in, email out.

When you sign up, you'll verify email addresses you want to allow sending from.

Been using it myself for a month and it's replaced my chaotic "bookmark everything" system.

Free to use. If there's interest, I'll open source the core and potentially offer a hosted version with extras (custom categories, integrations)—but a free tier will always exist.

Try it at https://itforlater.com. Happy to answer questions about the architecture or take feature requests.
