Not OP but I've got a 6 month old. I got some good advice from strangers and am compelled to pay it forward.

I highly recommend the book Happiest Baby on the Block, and even more so, the video (still sold as a DVD, but you can also stream online[1]). There are a lot of shorter videos of the author, Harvey Karp doing his thing if you want a taste[2]). The basic idea is that because humans have to be born early due to skull size, babies have a virtual 4th trimester. For the first 3-4 months of life the best way to help them is to simulate the womb environment using the 5 S's: swaddling, sucking reflex, swaying (really more like jiggling), shhing (white noise), side or stomach position (for calming, not for sleeping). The right combination of these will activate a "calming reflex".

Another good starter resource I recommend is the Wonder Weeks book and app. It marks out periods when your baby will be going through a "leap" in cognitive ability, which often are accompanied by fussy behaviour that seems to come out of nowhere. It's very reassuring to understand that your baby, who you think you had figured out, is currently a bit overwhelmed because they are all of a sudden seeing clearly beyond 8 inches or understanding that things are related to other things, and knowing that the fussing is a natural adjustment period to new skills and awareness makes their sudden shifts in behavior interesting rather than distressing.

There are also 3-4 pages of great advice in the book Bringing up Bebe on the French approach to "sleep teaching", which revolves around taking a few minutes to watch a baby who wakes up crying instead of just picking them up right away, thus giving them a chance to fall back asleep naturally, combined with the idea of establishing a window between midnight and 5am when you calm a crying baby down with any method other than feeding. This helps them to establish the idea of nighttime and hopefully means that the parents can get some sleep. 4 hours of uninterrupted sleep is a godsend, especially for a breastfeeding mom.

A couple of books that should appeal to a lot of the HN crowd are Emily Oster's Expecting More and Cribsheet which looks at various aspects of pregnancy and childcare from a research-focused perspective.

Sleep training is really tough, and there are a lot of books out there that repeat the same ideas. I found Sleep Sense to have a pretty clearly laid method for "camping out" or "graduated extinction" aka "Ferberizing", both of which are more gentle than Weissbulth's full cry it out approach. YMMV and there are a lot of strong opinions on this. I'm in the middle of this so I'm less confident to make recommendations.

Feel free to email me.

Clovertown was basically two Core 2 Duos in a multi-chip module, and capable of multi-socket system configs. The AMD fans at the time snickered at the MCM, for being a hack and a workaround, not a "true" quad core part. AMD didn't launch the "true" quad core server part until a year after Clovertown. That was the "Barcelona" Opteron 23xx, and it was terrible, and broken. To me that was when AMD faded.
Except the people who put those sub prime mortgages in probably didn’t apply rigorous statistical analysis to their situation.
I think what you're missing is that the comment you replied to never suggested OTPs are a replacement for e2e encryption. He only said that we can't take OTPs away from the bad guys.

I've mentioned this before, but I'd like to write a children's book that teaches one-time-pads. The book ends with little Jimmy getting hauled away by the feds for doing illegal math. Fun for children and parents!

The point of course, is to make clear how futile encryption restrictions are, and to perhaps make people wonder if it's really "the land of a free" when a child can commit a crime by doing some math. Fortunately, I think we're still a ways off from encryption being a crime.
In college we had a project to write a compression/decompression utility.

We had to implement all the data structures from scratch and implement several compression schemes.

I got the simplest one, run length encoding, working but couldn't get the fancier LZ77 stuff to work correctly. Mostly because I had trouble implementing some of the data structures required in C++, from scratch.

The professor had a few of the better students present their programs and one of them demonstrated that not only could they make smaller files than WinZip, they did it faster too.

It absolutely blew my mind and that's probably the day I realized I needed to really step up my game and put in the work if I wanted to be successful in this field.
Killing in self-defense is justifiable. Encryption is designed to hide information. Hiding information for privacy is also justifiable.

I think I will also start working on something like this on the side that encapsulates my budgeting knowledge. Should be a fun project. Thanks for posting and good luck.

No, not having guns at worst would deprive minorities of the ability to protect themselves. It is not only a hobby; it is also an effective means of self-defense.

There are 10^80 electrons in the universe, Eddington thinks.

Could you perhaps explain how it works in your country or other countries, in such matters? I'm not necessarily knocking any non-US or non-UK judiciaries or jurisprudence(s); in fact if anything I find US or UK systems poisonous too - as you describe it - to a high degree in some cases.

But how does a modern, complex and non-homogeneous society aribiter cases without turning "poisonous" or odious to some members?

To my knowledge much of Europe, M.E., Asia and even S. America are composed of largely homogeneous populaces with a smattering of outsiders at best.

The buildout in the article doesn't work. You can't plug in that 4-lane SAS SFF-8087 splitter cable into that motherboard. You're only getting 8 hard drives per motherboard with that setup, not 32.

That puts the cost of 192 TB at more like $6240‬, not $4945. Could be less if you find a good deal on mini-SAS PCIE cards, but still going to be substantially higher than $4945.
In a first world country like the US most people can save if they want to. It is not the 1%, more like the 80%.

Think about it this way. Imagine your household income is $50k, the median. But for one year, you decide to live like you are at $30k, barely above poverty. It may be a difficult year but there is no reason you can't manage, 1 in 5 people live their entire life with that. At the end of the year, you are left with $20k. You can now start living your life like anyone with a median income will. Because of that 1 frugal year, you are left with a average balance of $20k for your entire life. No more living paycheck to paycheck. And even better, when you die, your children will inherit these $20k so they won't need that year of poverty to keep their balance positive. So these $20k will actually last forever.

Of course, it is a simplification, but the idea is that keeping savings is just a matter of living with the paycheck of a few months ago instead of the last one.

Now what are the benefits of having an average of $20k that you won't touch.

First, it is insurance. Insurance costs you money in the long run, that's how insurance companies pay their employees. That sum is your own insurance for small things, like phones.

Second is that you can take advantage of opportunities, like volume discounts. Money will make you save money.

For those who are above the poverty line, the reason they can't save is lack of discipline. Not "the 1%". But to be fair, society in North America doesn't really help, with ads everywhere and credit everything.
It's spreading in Singapore, which doesn't have anything but heat. Average highs range from 86-90 year round.
Great idea - and this is an odd comment: I think you're pricing it too low relative to the number of people in the market. Just my gut - could well be wrong, wrong, and wrong again.
Do you have a source on that?

Really what is happening here is that companies that advertise on Facebook push conversions to Facebook to “close the loop”.

Unless a company is advertising a service on Facebook, there is nothing to push to them for this purpose. Are there Yelp and OpenTable ads on Facebook targeting users booking reservations? Have you pulled your results and see those?
With all due respect, that's not an answer, that's just reiteration of the same statement with a "because it would be better". The answer to "why" is a rationale and yours so far is "bad people doing bad things so better somehow force business to make sure their clients are legit and make things transparent", which is a perfectly fine opinion, but devoid of any actual analysis. That's my interpretation, though, and my apologies if it's incorrect and not what you've meant - I don't intend to introduce a strawman here.

I would recommend actually analyzing the pros and cons. What are the benefits for the society, why they're real (not a snake oil/security theatre, where bad actors would be easily able to work around), and why they overweigh the harm from the negatives (e.g. the obvious privacy concerns).
I think most people agree that a country needs a well regulated, armed militia to protect itself from nasty invading forces. But arming amateurs and everybody around is about as safe as everybody rolling out their own encryption algorithm.

It's odd, the safer our societies become, the more fearful people get.

My theory is the law of diminishing returns. We’ve made incredible progress in identifying and minimizing risks of disease and accident. Once we deal with those, we go down the list to the next one.

At this point, we’re working on things that are relatively minor risks, but still treat them as if they were high risks.
I think a lot of people are aware of prolactin because a lot of overweight men have manboobs and don't want them. But up to you, at least you're testing liver and cholesterol -- not everyone can say that. I listed it first because if someone would only agree to test one thing and nothing else, I think it should be prolactin.

Well the suggestion wasn't for me personally, it was for people doing keto. My contention is that if any of those numbers are off, they're probably wrong or missing something about keto.

Ask HN: Why was system admin re-branded as devops?
I am thirty seven years old who has been in the field for 11 years on-and-off. This just gives you only an idea of when I started. I have experience in writing web software for various commercial applications. I don't have experience with scalable design, unit testing, continuous development, or agile development methodologies. I am comfortable with the mechanics of writing small programs.

In most places, I would be considered a junior developer having some mastery over smaller scale work before delving deep into software production and design topics. This confuses several people when they see my years of experience, especially recruiters who usually have to cope with their own limited sense of technical knowledge to accurately fit workers into proper roles.

Seems like I have greatly missed out on a part of the pipeline that has creeping into more developer jobs, and I (possibly a bad luck thing) somehow has continued to evade this invasion through particular jobs that don't expose me to it.

Despite that, I tell myself and others that I am not a systems admin, but a developer. I have 0 experience working with an "operations" team and have little experience with the deployment part of the pipeline, with the exception of blogs and brochure-style websites that use shared hosting services.

My understanding is that it's the people that would be doing the job of fortune 50 companies if they were trying to roll their own data infrastructure?

If developers are expected to take more roles, doesn't that turn development into "second class" work if no one is left to fill a dedicated role for software development?

With the work I do, I just "throwing it over a wall" and we pay a third party hosting service to handle it. Uptime, stability, that's usually left on them so I don't really need to think about it.

Yet if new devops work involves more and more writing code for automation systems, then perhaps we need to make a case for why has rebranding take place. Has it been mainly due to shifting more responsibilities around different people?

> At my first job there was this grizzly old engineer who was known for being pretty surly

There is a VAST difference between "surly" and "asshole".

"Surly" is the result of dealing with legions of idiots for 30+ years. Someone who demonstrates "not-an-idiot" is likely to find the "surly" person quite reasonable and trustworthy.

"Asshole" is someone who engages in behaviors to your detriment and simply CANNOT be trusted. You either need to avoid these people or actively destroy them before they get rolling.

Unfortunately, it seems that standard corporate politics is unable to distinguish between the two.

The idea of making file reads stateless is interesting. I wonder if it's atomic too? I think that might be very useful to have.
Scaleway C14 [1] gives the $2/TB/month that the title promises. Now, providing Sia storage space may be more expensive because you have to calculate costs for proof-of-storage (and may not be able to pull off the "cold storage" model, which may also only work in conjunction with a higher-priced low-latency offering), plus potentially more replication than a centralized service uses, but it does indicate that it's probably not completely unrealistic.

Ask HN: How important is math for software engineering?
I'm well aware that you can learn programming, data science, etc... without being good at math, but one thing I always keep hearing is that; the better you are with math concepts, the better your problem-solving skills become. Seeing how many things in programming derives from concepts in math (functions, vectors, matrices, etc...), do you believe having a strong foundation in math would help someone in this type of field?

I really want to hear your opinions on this, how much beneficial is math for software engineers? Does having a strong foundation lead to better problem solving? If two programmers were assigned a task and both of them have spent an equal amount of time (let's say 10k hours) practicing programmers, but one has better math knowledge than the other, would that person be able to produce a better/faster solution than the other guy?

I've said this before, but I really don't get any useful results from Google at all anymore. I have to prefix Reddit for every search to at least try to get a vaguely human answer to a question.

Of course Reddit is still gamed and has plenty of other issues, but far less than Google at this point.
It does sound like that! The mistake there was to assume the failure of one mortgage was statistically independent of the failure of another, which is obviously incorrect for many failure scenarios. In this case, it it would be similar if all nodes were in, say, the same datacenter. That doesn't appear to be the case, but there may be other dimensions on which the network lacks the required diversity to support the reliability claims (disk vendor and age...? There must be others.)
> If there was a demand for sorta-reliable, they'd build a sorta-reliable S3 and undercut you.

Amazon's goal is to get people to pay a premium to get access to their entire ecosystem of services. They don't optimize the price of each individual service. There's a lot of take it or leave it for their specific offerings. Look at how they used to have reduced redundancy as a cost saver, but don't anymore. If you want corner-cutting storage from Amazon, you get funneled into Glacier now.

So let's look at how glacier deep archive is $.99 per TB per month, with a waiting time. And Google's weird offering where it costs $1.23 per TB per month, with instant access, but you pay a bunch of money to access. That means they can't store it on tapes, but they expect to profit anyway. And they're probably not running that as a loss leader that depends on the archival data being accessed.
