> 2. Pick a simple device. Don't start with the USB stack or Ethernet. Maybe try to reimplement the UART driver first.

A UART driver is great; then if you want to do Ethernet, virtio-net is a good start, and then carefully pick your physical ethernet card; something descriptor based will let you reuse the descriptor concepts you already learned. Realtek cards get a lot of shade, but aren't too bad to interface with and they're very popular; if you've got a bunch of computers, you've probably got at least a few realtek nics. Ethernet is cool, because then you can start communicating with the world (although there's a lot of stuff to get tcp going)
THC infused foods are actually quite simple to make, and no spraying is needed.

THC is fat soluble so at the most basic level, infusing butter with cannabis flower will yield cannabutter which can then be used as a substitute for butter in just about any dish eg. The classic pot brownies you hear of.

The only complexity is dosing, which can be somewhat estimated if you can guess the potency of the flower. It's all a bit back of the napkin math, but you can get a decent estimate. One of my side projects (learning Vue.js) was a edible calculator for doing just this: http://www.scientificedibles.com

No, it’s common - particularly among people who were on Twitter in its earlier days; 2007-11. A whole lot of people I know came together during those years via Twitter, as well as blogs and offline meetups, but Twitter was the glue that kept people interacting day-to-day, and plenty of those people remain good friends. Indeed I pretty much met my partner over Twitter in 2010, we got together after group social gatherings in 2011 and now we have a wonderful son together.

Things are very different now that it’s so dominated by politically-charged rhetoric and piling on, and I can understand that new social connections would more likely get drowned out these days.

Forth is very expressive. You just need to know how to use it. Like Lisp, you build the language you need in it, and then write that.
Totally agree not trying to be critical of YC. Situations like Juicero, Theranos, this topic, et al scams, are interesting to observe.
A startup is just so difficult that you really can't get away with stuff like that and survive.

It's very rare you can fire your dev team and get away with it, your product will not be good enough for years on end while you learn and grow. On the flip side customers will wonder why their point of contact is now gone if you fire the main contact they were dealing with. Plus how are you going to get more of these customers now?
> Nobody is preventing you

You were advocating in favor of using the government to "enforce a contract" or whatever, on people doing what they want with the phone that they own.

> You buy the phone or you buy a librephone.

And if someone buys an iPhone they should have the full right to do whatever they want with it, and the government should absolutely not be preventing people from doing so.

> Let’s leave the government out altogether.

Yes, lets ensure that the government never prevents anyone from doing what they want with the phone that they purchased.

So if you take back your previous statements, and instead agree with me that the government should not prevent people from doing what they want with their phone, then cool.

But otherwise, if you disagree, then you would be the one advocating in favor of using government coercion here against people.

Can confirm. I spent many years in the Midwest and it is very common for strangers there to engage you in conversation randomly just to be nice. In contrast, in most East Coast cities, whenever people start up a conversation without an immediately apparent goal, it is to set up an ask for money.
Brief mention in the post, but FYI to the thread - .NET Foundation is an independant non-profit (501c6) foundation that supports the .NET open source community. It's run by a community elected board and funded by member donations and a diverse group of corporate sponsors. This is a great example of the kind of work they do to support the community.

Disclaimer: I was on staff at .NET Foundation 2016-2019.

It doesn't really matter what language you use at the high level, as long as it is calling a highly-optimized, aggressively-compiled, native-instruction-set kernel for most of the work.
But in this you can also see the difference between an American and many others. I find the "how are you greeting" very tiring nomatter how I am. When I am being asked the question I internally go through an assessment of, how am I today, how interested is the person, how much do I want to share of this. It takes significant mental effort.

When I was a teenager I did a one year high school exchange to the US and for a long time I really struggled with the daily "what's up?". I was going through the above internal dialogue more than 10 times a day struggling to come up with an answer. Even, when I learned to just answer "yeah what's up" internally the dialogue would often still be triggered.
Thanks for the details. I'll do some more digging.

Also, why do you think a CIA-affiliated site would do a write-up on this? Seems like it makes soldiers and their secure info look bad.
Getting into YC is an accomplishment, but you clearly don't have a real business yet. To paraphrase a saying... the reason that startup politics is so vicious is because the stakes are so small.

It's painful but in general I'd try to move on and be thankful that you were able to end your journey with that CEO early, after only a year and a half! Life is too short.

Still it's worth the effort to do a few legal consults to know your options. Litigation is one, but it's emotionally draining and could drag on for years. How good was your bookkeeping? Did you have a vesting agreement? Did you sign away your IP? Did you sign any non disparage agreements - you could be sued for damages, especially if those communications are written.
This falls into the category of the classic “Stupid shit that most programmers believe”.

Fundamentally, the problem is that if you’re trying to validate an e-mail address as being correct and you’re not sending an actual e-mail message to that address, then you’re doing it wrong.

I am American. I have transitioned from saying "How are ya?" as a greeting to "Good [day,morning,evening]" etc. It's every bit as polite and does not feign concern.
Incorrect. Pfizer, Moderna, and J&J use a pre-fusion stabilized sequence. AZ does not.

However, all currently used vaccines are just the spike (S) protein plus possible non-COVID proteins (in the viral vector vaccines), so none will induce antibodies against the COVID N protein.

I imagine it might be possible to guess whether someone was vaccinated with the AZ vaccine based on whether they have antibodies that are specific to the site that’s modified in the stabilized sequences. I don’t think anyone does a test like that.
> It's accepted truth among gamers and power users, that ECC is waste of budget.

A waste of budget at what price?

Are they actually looking at $80 of ram becoming $90, or are they looking at it becoming $160 and slower? Which is about what I see when I go check newegg.

I don't think you can extrapolate current decisions to a world where adding ECC is 12% of the RAM budget and 1-2% of the total budget.
> wonder if there is space for a twitter clone

Mastodon have been a pleasant alternative to Twitter for me, but the experience is highly dependent on the instance (server) you choose to join. But the fact that virtually every server is community owned, contains no ads or algorithmic feed is making a huge difference.
You would be lucky if any actual THC is involved, nowadays its mostly synthetic semi-legal cannabinoids in the black market, at least in Germany (apparently even in some coffee shops in the Netherlands). The market desperately needs to be regulated.
Ask HN: How to cope with the death of a dear person?
My father-in-law passed away three days ago. As it happens with these things, it was too soon. It's always too soon. He was like a second father to me.

He had a career in the Italian navy, a retired Admiral. He was a great storyteller, and had a tough and difficult character, but lots of good things, deep inside. Full of integrity, honorable.

Thankfully we moved back to Italy a few months ago after a dozen years abroad, and spent this time mostly with him and his wife, in their hometown, Venezia. I can't imagine what it would be if we stayed in San Francisco, and this death happened at distance.

Does any of you have a time machine at hand? Both me and my wife would like to tell him how much we love him, and hear his great stories one last time.

Missing that, any suggestion on how you coped with death?

It is not my first time; but it is the first time in the last decade or so. I know, I'm lucky.

One last thing: I don't want to just "ask", but I'd like to contribute something. This is my suggestion for you, actually my prescription for you: if you still have parents, or parents-in-law that you really love, invite them out for dinner, and ask them to tell you stories of their past. Then, before saying goodbye, tell them how much you love them. One day, far away in the future I hope, you will thank me.
Thanks.

Required 'brew install wget' first for me. ;-)
I like cowboy boots as a substitute for dress shows, a nice pair of dress boots are dress shoes that I can be on my feet on all day, without killing my feet (even ones with a high cut heel).

I also have leather soled pre-aged oilskin boots that have been covered in mud at various points in their life (the best 50 bucks I ever spent - you cant go wrong with 50 dollar pair Tony Lama boots, the pre-aged material means they felt wore-in right from the first time I pulled them on) - yet clean up nice enough that I can wear them to a meeting, as well as rubber soled western style boots for work (two otherwise identical pairs, one in steel toe, the other in not steel toe - I loath the narrow toe box of the steel toe ones).

That said, I don't wear boots or anything with a hard heel inside my house, for fear my downstairs neighbors would kill me in my sleep. ;-)

As far as me? I'd love a ranch, with cattle, but in the mean time, I'm perfectly fine being all-hat, no-cattle, besides, a cowboy hat is practical here in Texas (was in Washington too), and frankly so are boots most of the time too, besides, western shirts generally look nice, and wear well too.
That paper demonstrates that the vaccine provides a stronger response to the part of the virus that the vaccine tries to get you to respond to than actually getting sick does.

It does NOT demonstrate that the vaccine provides any response to other parts of the virus. And it almost certainly does not, while getting sick does.

It also DOESN'T address the question of which provides a better response to novel variants of COVID-19.
I remember taking a doing-biz-international course - one thing that was stressed was that personal space is different for different cultures, you can back someone into a wall if your normal speaking distance is larger than someone else's.

FYI for Americans a good rule of thumb is that Americans are comfortable at roughly an arm's length - reach out and touch someone's shoulder with your knuckles - after taking that course this became a company greeting ....
The software side, they’re so far ahead it’s ridiculous. Google couldn’t put out a watch to match the generation 3 Apple Watch today. They probably couldn’t even do that in 2-3 years. Same goes for Microsoft’s and Amazon.
>You can see from the figures released by various governments on testing rates vs cases that the false positive rate on tests is very low

This sounds like circular logic, or I'm misunderstanding what you mean. How were these "cases" confirmed? By testing? It would help if you cited the figures where the reliability of the tests can easily be seen.

Btw, my point was exactly that the issue isn't with the test itself but the interpretation thereof. Most people do not understand how they work and so they don't understand that even healthy people can test positive depending on the criteria we use to define "positive". But positive doesn't mean sick and it doesn't necessarily mean infectious either. By itself it doesn't mean anything.
By coincidence, my uncle got the covid nearly at the same time he got his Pfizer shot. Later, the symptoms became too serious. It seems that the vaccine didn't have enough time to protect him. He went to the hospital where he discovered he got the covid. He was under oxygen for weeks. Luckily, he recovered, but lost so much weight and now feels very weak. This is just one example, I don't know whether it would be different or similar in general. Nevertheless, it is still a reason to think that maybe it is not a good idea.

My experiences with Sales in the driver's seat have been pretty bad.

One Sales exec thought it was hilarious to petulantly insist that our products be "zero cost, perfect, and shipping yesterday", dismissing out of hand small stuff like iron triangle, budgets, P&L, schedules, etc.

Another Sales exec, troubled by our excessive salaries (read: below market), denigrated our dev and ops teams by saying "All y'all do is type on the computer all day. How hard could that be?"

Etc.

(I don't know that engineering lead orgs are any better, overall. I've yet to experience the mythical balanced combo Sales, Engineering, and Support org.)
Voice over IP: Protocols and Standards (1999)
I have the same question. End-to-end http3, especially with the WebTransport API (available to test behind a flag in chrome), will be a huge boon to real-time games and conferencing. Http3 to the origin and http3 support in cloudflare workers (including sending and receiving datagrams and bidirectional streams I hope) will I think really push the web forward once more and more browsers and backends being to support the protocol.

Anyone from cloudflare know if this is on the roadmap?

Ask HN: Is this a theory/rule in Mathematics?
Hi all, I recently was daydreaming and had this silly thought experiment about adding two random integers chosen from an infinite set. I tried searching online for something similar to my thinking but came up short on explanations.

I have no real background in mathematics outside of undergraduate calculus, so was wondering if the more math-curious people here could point out some rule/theory this may be related to, or find some illogical gap in my daydream :) So here goes...

If you pick out two random integers from an infinite set and add them, there would be a 66.66% chance of that sum turning out to an even number. This is based off two conclusions:
1. There is 50/50 chance of picking out an even or odd integer from infinity
2. 2 of the 3 possible sums would lead to an even sum (odd+odd=even, even+even=even, odd+even=odd)

So if you were to keep taking two random integers from this infinite set (which would be for... infinity), you'd come up with an infinite set of integers which now 66.66% are made up of EVEN numbers.

If you were to keep repeating this process of pulling two numbers from your freshly created infinite set of summed integers, each new iteration of that set would be an infinity made up of more and more even numbers over time. So each set would get closer to a 100% collection of even numbers, but never quite getting there as it approaches infinity (the percentile of even numbers in your sets over time could be plotted out as an asymptote). You end up with an infinity of sets, all approaching a complete infinity of even numbers.

...

Very, VERY, useless(?) and random daydream, but it got me curious to see if one of my basic assumptions about working with infinity is wrong, or find others who have done similar though experiments (I'm confident I'm not the only one).

Thanks in advance to anyone for their input.

Sincerely,
A Math Noob
> On a tangential note, I'd like to take a moment to recognize the amount of work that Apple has put into its accessibility features. Assistive Touch on the apple watch will probably serve a remarkably small portion of the user base

On a similar note I’d like to point out that accessibility affects everyone. You don’t need to be disabled to enjoy accessibility. My eyes are fine, (I think), but I find the iPhone X’s lowest screen brightness too bright iOS’s blue filter to be barely effective, so I use a custom color filter (almost full red) and “Reduce white point” and am super happy it’s an option. People used and probably use assistive touch for things that don’t compensate a disability, but just add useful features. The back tap shortcuts are just a nice feature. The zoom is nice if you want to show something to someone a bit further away. I could go on.

As someone with perfectly fine hands I love this feature because one thing I hate about modern smart watches (RIP Pebble) is that you have to touch and inevitably smudge up the screen. Bam, problem single-handedly (what pun are you talking about?) solved. Massive kudos. The other, more obvious advantage is that your other hand stays free, of course.

> and perhaps costs more to develop than the return they'll ever see on it.

As you see, the user base for such features is bigger than you may think. Besides collecting some easy sympathy points for helping disadvantaged people, Apple also seems to be huge in the business of servicing small, but under-served and vocal minorities (where can someone who wants a modern, small phone go?), which will turn into strong advocates for their brand.
I can understand Troy's rationale, but I would prefer someone else than the .NET Foundation. The foundation should focus on .NET and not be a kitchen sink of everything written in .NET.

I don't assume that is what the gp is saying.

The more obvious point is that the forces that result in inequality don't originate in crypto, and any serious attempt to oppose these forces should target the origins.
We absolutely have enough data to rule out meaningful ADE. Study after study (the phase 3 trials and all the ongoing surveillance) indicates a massive reduction in the rate of severe infection among vaccine recipients.

Sure, one can quibble about whether maybe some of the very small number of people who got a vaccine more than a couple weeks before a severe COVID case had a form of ADE, but that’s like saying that we haven’t ruled out that seatbelts might kill people. In both cases, the risk that a protective measure harms the recipient is massively outweighed by the degree to which the protective measure protects the recipient.

> Of course it can be solved, just not on a public pseudonymous forum.

Here is an important observation I think I've made over the years:

All else being equal, the HN model (full names voluntary, IRL connection voluntary i.e only username and password, long lived profiles encouraged) has been better for interesting civil discussions.

Why?

Full name policies only encourage this explosive mix:

- People who don't realize the foolishness of commenting publicly using their full name on a controversial case.

- People with fake but real-looking accounts.

- People who realize it is stupid but does it anyway sometimes because even newspaper comments sections deserve some adult voices.

Very many of the people you'd want to hear from are silent because they don't want your name mixed in with the regulars in the comments there.
Superluminal speed is called "instant" in physics.
I should have qualified that I meant it in the context of overwork. Almost nothing we do is so crucial that sacrificing people’s lives to overwork so the deadline can be met is morally justifiable.

There are very few mission critical, literally life saving exceptions. 99% of it all is not: if the TPS reports are done a week or two late, no one dies and nothing explodes.
TBH I think right now it's more of an incentive thing. Consider that:

a) Attackers would have to develop the POC. This will require a somewhat different skillset than typical exploitation, so there's effort involved.

b) Rowhammer is best for privilege escalation. For desktop users (where the most money is) privesc is already pretty trivial - no need for fancy exploits, you can pretty much just ask for root or use a much more straightforward exploit.

c) Exploit devs don't typically like a lot of attention. You don't want to be the first person selling rowhammer exploits unless you can charge out the ass for it, because you're gonna get way more attention for it.

These incentives aren't super technical, they're mostly market driven, and it's why we don't see fancier attacks in practice, even if they're practical. As one attacker I know was saying to me, they wish they had an excuse to do the fancy thing, but it's never worth the investment when you can own boxes way more easily. Another hacker said "I don't want a Krebs article on me because I did something clever".

NSA's incentives are not super difference, except they're not as directly financial. They also have crazy resources to fuck around with this stuff, so it would make sense that they'd demo it in a lab. Would they actually deploy it? Eh, doubtful. Against another advanced defender rowhammer should be pretty detectable by monitoring ECC metrics, and again, why would you do something fancy when you can just buy 0days - the USG purchases hundreds a year from private companies and develops more themselves.
On HN to uphold civil discussion it’s best to avoid dismissive references and assumptions directed at “you”. Best to address the idea alone with your example/argument, rather than the imagined speaker. Otherwise it can be interpreted as needlessly antagonistic and will be downvoted.
