> They promise modern process isolation and fail to deliver it.

Before one makes such a statement, one has to define "modern process isolation" in a very formal way, so that not anybody (neither Intel nor the customer) can redefine the meaning as they desire. I am not aware that Intel gave such a formal definition that they claim to obey to (but perhaps fail). So any operating system can only rely on very weak guarantees for the processor to provide "isolation" (using quotes since I have not defined the term "isolation" formally). Thus the OS has to implement stronger isolation primitives that it desires by itself (by using the weak primitives that the processor provides).
On the contrary, this is probably good news as we are nearing the carrying capacity of our planet. I don't think birth rates will ever decline to the extent that the global population collapses but a declining birth rate is really something to celebrate.
I agree it's a good move from Microsoft to make Excel more accessible. It's just not something I was expecting the first time I stumbled upon the problem.

I have a programming background so I'm used to searching everything in English, even though that's not my native language.

I inserted sqrt() in my non-English Excel and it didn't work. I thought I had a completely broken version of the program.
Took a while to figure out it was a language problem!

I was a single parent for six years and regret not a minute of it. But my own mother’s advice to me many years ago was, “Don’t have kids. They mess up your life and I regret it.” Although I wouldn’t have existed otherwise I am sorry for her that society 50 years ago dictated that she had to have kids.

I loved this quote in the article:

> One commenter called Dutton “an utterly miserable, cold-hearted and selfish woman.”

It’s the commenter who was selfish, presuming some obligation on the part of Ms Dutton.
Art hasn't always been about scarcity there's a long history of public art, in ancient Egypt far from being scarce art was everywhere but art was effectively sponsored by the government in ancient Egypt. You didn't sell art to a collector you were sponsored by the government to make art that was everyone to enjoy.
In general, I think that readers/posters/commenters here at HNews are above (? not sure if it's the right word) the average population in terms of reading, thinking, planning ahead (and are even able to discuss planning strategies like "should I go waterfall or RUP or Agile or XP or...").

And it's easy to notice that this subject arises many points-of-view without any effort.

Extrapolate that to the whole population, where some pregnancies happen without planning, without even noticing, without previous discussion between the couple, or even without too much thinking ahead for single-alone parents.

Yes, given that each child is different, it's no surprise that hardly anyone is prepared to be a parent, and that parenthood can last even after you have grandchildren, becaus yes, even when your child marries and get their own children, you'll might end up helping here and there.

I really appreciate that people outspeak about how hard is to be a parent, because the easier way is to do like those who are inside the cold pool.
Ask HN: Finding an advisor or cofounder?
Hi all,

I am a software engineer who is making a lot of progress on a personal project that I believe would make a great business. I am able to handle the technical work by myself for now, but I really need someone with experience in the industry I am targeting - healthcare & medicine.

I am not keen on blindly reaching out to healthcare professionals in my city/abroad, but I am willing to do it. I am just curious if there are any people on here who work in my target industries and might be willing to discuss my concept. I am open to anything from a quick email conversation to a possible co-founder for this business, should it get to that point. For those who are interested, you can reply here or find my email in my profile.

For the sake of discussion, any insight into finding non-technical founders in other industries would be greatly appreciated.

Thanks!

I don't understand one part. If you read from an arbitrary memory location (during speculative execution, I get all that) how does that read pull data from a different process? Aren't all addresses virtual until they go through the MMU and get translated to a physical address depending on the process?

Or does this work only because the kernel exists in the same virtual address space, hence KPTI as a mitigation?

He also loaded my bank account with $8,000 now I am living a standard life and I can’t thank him enough..He’s blunt and honest..And he respects whatever agreement you make with him..You all should give him a try for your credit score boost.. send him an email : Gmail: cyberghosthacker830 OR Outlook: cyberghosthackers

Can confirm. I visited just after Trump left, and the air was pretty good.

Also, I've heard from locals that they're starting to relocate dirty industries to nearby cities that foreigners tend not to visit. I visited one, and there were a few days of pretty bad smog (but blue skys some days, too).
When I worked for a large company and had to cross an international border that was considered risky (e.g. China) we were issued a special phone and laptop just for that trip. They were wiped after each use. If one was especially paranoid it doesn't seem unreasonable to destroy the devices after use.

This way we could consent to search because the devices were blank. It's highly inconvenient and I hope the US doesn't turn into a high risk border.

> "The difference in mind between man and the higher animals, great as it is, certainly is one of degree and not of kind."

I think deep down we all inherently know this. This is largely why I try my best (although it is difficult) to eat mostly vegetarian. I think if it were a matter of survival killing and eating is natural, however what we do with live stock and factory farming is obviously unethical.

It's hard to watch footage of the process, from birth, life, and ultimate death of animals in captivity. It reminds me of a video game I played called "Prey" (great game, worth playing even today).

A recent film that strikes this chord but misses the chance to drive it home is "Arrival" (2016). Another recent film is "Bladerunner 2049" (looking at the farming practices of both protein and replicants)

There are countless documentaries on Netflix (and likely other services) regarding factory farming animals which are worth watching. They certainly helped clear some of my own ideological barriers.

Pinyin input for Chinese is similarly phonetic. Supposedly there is a method popular in Taiwan based on strokes.

Reading characters is a bit faster, but only because you had to memorize 10,000 of them already. People reading English will similarly chunk many of the words they are familiar with so that they are not so much read as they are recognized.
I married my wife 10 years ago. When we got married she was ready to have "at least 3 kids". Now she is not even sure she wants 1.

I know it sounds selfish and absurd but we enjoy our life so much: all of our time we spend with each other, we travel 4-5 times a year to different countries, on the weekend we go for hikes in some national parks close to us. I could go on, but the theme is that we enjoy a lot our company and both me and her we are terrified of changing this.

And if that was not the selfish part here it comes: I am actually afraid for both me and her when we are old that no one will come to visit or we won't have friends in this late stage in our life, we have moved to different countries 3 times.

Those that have more or less the same lifestyle, how and what do you deal with this? I am quite interested in learning how others cope with the selsifh feeling that you should have someone to be with you.
Or he could just go to his local post office and get a box and ship it there.
The first few times I casually mentioned I had never been interested in having kids, the reactions were unreasonably vitriolic: "Well, you aren't a good person and should stay away from them then!!" and "You look like the sort of person who doesn't want kids", etc. I eventually learned not to bring it up.

Thankfully I was never forced into it by marriage or otherwise. People who want children can have them and people who don't want them should not be shamed into it. Kids would be better off being genuinely wanted.

I personally was an accident kid, born before abortion was legalized and there was always a subtextual theme of being unwanted in my childhood. I decided early that I would not have a kid unless I really wanted one. And I never did have the desire. I'm glad I stuck to it and didn't give in to the immense peer pressure.
Ask HN: Life saving study tips/hacks for CS
Hi HN,

I'm about to take a few MIT OCW courses (namely calculus, discrete math and algorithms, For those of you have gone through a similar program (or a regular University Curriculum), how did you study effectively, is there any process for taking/reviewing notes ? Any advice is greatly appreciated.

Thanks
I've thought about this idea and have a proposed mechanism for it...

We dont have very strong opinions outside our areas of expertise of knowledge, we dont have the inclination or the capacity to really.

Whereas within our area of expertise we have cultivated our understanding to be able to fully appreciate and love great works, but also truly understand and thus hate the depths of failure of poor work.

I suppose this is similar to the original uncanny valley effect. A part of our mind is highly specialized at recognizing other humans with an amazing attention to detail. Real humans are registered by the system and pass, quasi-human things register and fail alarmingly, rocks and trees merely dont register.
I've never done it intentionally, but as someone who occasionally has lucid dreams #2 definitely seems accurate. Much of the time I lucid dream it's when I'm sleeping extremely lightly right before I wake up.

In fact, I know that I'm dreaming and that if I open my eyes (somehow separate from opening or closing my eyes in my dream) I will wake up. Sometimes I might shout or say something in my dream and I actually say it out loud and that wakes me up as well.
I mean, I was definitely just joking. But I also think it’s a reality that we have to accept that despite our best intentions, much of what we make will be consigned to the dustbin of history. Only a small percentage of our products will ever break through that barrier to becoming truly useful in a lasting way. That’s not a failure in my eyes; that’s the reality of innovation, and the system is working the way it has to.
People love comparing countries for their non-mental healthcare (physiological care?), but I never seem to hear about countries that actually have good, functioning mental healthcare systems.

New Zealand has what could be described as a well-functioning (most of the time) healthcare system, if you break your arm, it's not a worry at all. But the mental healthcare system is a complete shitshow.

It's an absolute disgrace, especially considering that NZ has the highest youth suicide rate in the world.

A process that I've heard some financial people developing (highly secret/proprietary/potentially valuable) software use when traveling is:

1. Store confidential data on company servers or a secure/trusted/audited cloud service.

2. Protect that data with two factor authentication, ideally with an ephemeral/rotating factor.

3. Incorporate a duress code into one of the auth factors (e.g. "add one to the google authenticator result when logging in or you get fake data/get permanently locked out until you human-authenticate to regain access"), ideally both.

This is far from perfect, but reasonably secure and not terribly inconvenient in practice. Additional layers of protection can be added to the duress process, like defaulting to under-duress behavior until a certain timeframe (i.e. you're being searched at the airport and not during your appointment time slot), or when from an unrecognized network location. Like all duress-code-based responses, it is vulnerable to humanity (e.g. torture/intimidation).

This is a funny statement, because it is prefaced with a pretense of abandoning human exceptionalism, and then goes on to ask a question with implicit human exceptionalism; As if the ants need humans to take care of them even though they've been around for ~92 million years.
UK citizen here. I'm not aware of any policy in the UK that forces travellers to hand over their device passwords - i.e. not in the same draconian way that's happening in the US. Border control in the UK is pretty well overstretched as it is. I don't think they've got the resources to perform this type of intrusion, even if they wanted to.
I wouldn't call the concept of parenthood cultural. There's a pretty substantial biological component.
Diagrams on how to negotiate with people around the world
I have three boys, aged 6 months to 4 years. It is extremely hard work and a major life change, especially if you get started in your 30s (as I did) after having already established yourself financially and professionally (yes, the resources makes it easier, but you've also had the time and resources to habituate yourself to a comfortable and self-oriented life, and you're not quite as robust as you were in your 20s, when an all-nighter was not a big deal). It also puts strains on even strong marriages.

But it has lots of irreplaceable moments and provides a general sense of satisfaction for well-spent effort. I echo several comments on the joy of seeing my boys develop as people, learn, ask questions, and explore. Even the squabbles bring back fond memories of my own childhood tussles with my two brothers, and how those interactions are part of children learning how to relate to other people.

Aside from all that, once they are born (and beforehand for my wife and me), the profound sense of duty to care for them compels putting any thoughts of self aside. We alone chose to create them and we alone are responsible for raising them to be good adults. I'm not going to shirk such an important duty in life. Such a sense of duty is a cultural norm encouraged by community moral condemnation of those who fail to adhere. I reluctantly support such condemnation as essential for the successful continuation of our civilization. As such, I say that parents who shirk their duties are committing a moral wrong and should be criticized.

The article doesn't come out and say it, but it seems to suggest that this is widespread. I don't think that is true. Watching my parents' generation embrace grand-parenthood, and the explicit statements that many of them make about the importance of family, convinces me that the vast majority push through the tough parts and find the overall experience to be the most important thing they did in life.

Final point, and one that I am cautious to make for not wanting to offend anyone needlessly: I know plenty of singles and couples who are childless, and several that are childless by choice. Suffice it to say that my anecdotal view is that sadness, eccentricity, and empty hedonism seem to develop over time in these couples, especially in the women.
> We've just seen the one, but we've only had the capability to detect something like that for ~5 years. So in the absence of further data, it's reasonable to conclude that `Oumuamua-like objects pass through the solar system once every 10 years

No it's not. It's impossible to deduce anything from a sample size of 1. (And yes I realise that this invalidates my point as well.)
Yes, meltdown only works if the kernel is in the same address space. Also, the kernel maps the whole physical memory as part of its address space somewhere (kernel phyiscal map), so if you can read kernel memory, you can read all phyiscal memory.

And you are right, KPTI is a full fix for Meltdown (but not Spectre).
I was just thinking about this the other day. Large familial units have pretty much been the modus operandi of humanity since the beginning. It's not just adults taking care of kids, the kids take care of the kids also. Each generation has their own sense of responsibility for the generation before them because that's the established culture. After a couple generations, the responsibility loses its feeling of work and simply becomes an expected aspect of life.
You clearly haven't been paying attention or reading about how this works.

Heartbleed was touted as being bad by those that didn't read too far into it. You could scrape memory, sure. But it was always random fragments. This lets you make targeted address attacks. Force a process to use that memory space through a NOOP and now you can start scraping at will. Or you can just do an entire memory dump and pull things out in plaintext (like scraping Firefox passwords, which we've seen done already).

The only reason this isn't worse is it requires the ability to execute code on the machine. It has high (near absolute) impact, but low-to-moderate on the ease of execution.
