You are underestimating 1) the number of CA's embedded in your browser, 2) how easy it is to get one of those CA's to issue a cert for someone else's domain.
Why? Leftist people would also get more diverse recommendations. They'd be exposed to arguments such as the importance of maintaining western values etc. I actually did an experiment of wading through videos recommended based on anti-Merkel stuff. There are very few reasonable discussions and mostly it's horribly populist and poorly researched stuff.
While there's no harm in supplementing with small doses of Magnesium, it's also very unlikely to be the sole causative or curative factor in most people's depression. I'll address your studies individually:

[1] Refers to case studies (e.g. clinical anecdotes) of depression recovery following magnesium administration, but the number of cases is omitted. More importantly, there are no placebo controls to differentiate between spontaneous or placebo response and response to the magnesium supplementation. Finally, the article is in the context of severe magnesium deficiency, which is a strong selection bias that prevents the anecdotes from being extrapolated to the general population anyway. (Yes, I am aware that much of the US population does not meet FDA guidelines for magnesium intake, but that's not the same as being deficient in magnesium in the body).

[2] Is a good example of the importance of noting which journal the article was published in: In this case, it was published in Medical Hypotheses, which is dedicated to promoting diversity in debate by publishing hypothesis and fragmentary ideas that don't yet have enough real evidence to publish elsewhere. The first study it cites is from 1921, which was not placebo-controlled. The second study cited is from a journal dedicated to Magnesium research, but more importantly which pre-selected for patients with hypomagnesia. In other words, the study examined whether Imipramine (an anti-depressant) or magnesium supplementation were more effective in elderly type 2 diabetes patients who were known to have hypomagnesia.

[3] Refers to animal studies, but 3 of the 4 cited articles are about magnesium in migraine headaches. Perhaps the full-text articles have some embedded murine studies, but otherwise I don't see much evidence for magnesium treatment in humans here.

In short: It can't hurt to supplement, but it's unlikely to be curative. More importantly, recommending weak or unproven supplements to depressed patients can send them down a path of attempted self-medication with supplements that do not work, when proper medical treatment can work much more quickly and effectively.

The attack described in the article (web server compromise) would not necessarily give you access to the DNS of your domain (that's putting a lot of eggs in one basket).

It's certainly an effective defense-in-depth mechanism.
It's just an artifact of 32-bit addressing. Addresses are just an integer from 0 to (2^31 - 1). Using a smaller address space may be possible (although it is still very limited), but dealing with anything other than exactly 32 bits is a TON of extra work, and so it's not reasonably to accomodate what is really a non-issue.
When I was an undergrad, many years ago in my home state of Ohio, community colleges were definitely looked down on as being "lesser" than four-year universities, even if the universities were offering two-year Associates programs.

However, the State of Ohio overhauled how it helps funds state universities, where funds are allocated based on graduation rather than enrollment. As a result, state universities have started shifting more and more students to take low level courses at whatever community college, or colleges, they partner with. In particular, students with higher drop-out risk also get sent over to the community college.

I think that, along with many of the State's public universities slashing tuition on entry-level courses have helped improve the cost burden of higher education, particularly for those high-risk groups where they only take a few classes and fail to complete the program.
>They could have simply adopted blitz chess rules, where the goal is to capture the opponent king, and leaving your king in check is not illegal, to avoid all this extra computation...

Those are not blitz chess rules. The goal of blitz is still checkmate, not capturing the opponent's king. USCF, FIDE, WBCA all agree, leaving a king in check is an illegal move and loses the game as soon as it is pointed out.
Funny, I have the same lockups with Chrome. Middle-clicking a new link (to open in a new tab) freezes the entire browser (all tabs) until the new tab is done loading. I believe it's a extension problem (uBlock Origin, EFF Privacy Badger), but I don't really want to get rid of any of them.

Speechless.
Untreated meaning what? Un-medicated? I don't see that as a bad thing. The cause of depression is seldom one that medication alone can overcome.

Therapists... they're probably useful for some people.

For others, man what they wouldn't give to just have a few more friends, or something to do / some place to go where they felt welcome and needed. Medication doesn't help give people purpose or cure the underlying behavior that prevents them from building friendships.

This is a complicated thing, since there's no guaranteed cure for everyone, there's no reason to be concerned if people seek different ways to combat this deeply personal problem they face.

Some generic advice... eat healthy, get some exercise in the sun, keep your room clear from distractions (tv / laptops / cellphones) so you can sleep... just do the best you can. One foot in front of the other. Try and be social if you have the energy for it.

And that is an absolutely fair point. Police departments will need to evaluate the cost/benefit of any equipment they use. (And damage that equipment can cause to roadways also factors in as well.)
Has anyone here actually tried ayahuasca and can share their experience?
> Why didn't ITT seek accreditation so that credits were transferable?

Accreditation and transferability are different issues; ITT was accredited (were it not, it could not have participated in federal aid programs.)

> It seems like it would instantly increase the value of what they are selling.

Like Corinthian, what they were selling was largely fantasies, specifically targeted to demographics who were unlikely to recognize that they were fantasies. Were ITT intending to sell a legitimate education, sure, transferability would increase the value, but they were never going to sell legitimate education at the mass-market volume and premium prices they were trying to sell at.
Judging from history, cheap colleges in the post-war decades worked just fine for the boomers.
The 2000mAh value seems low for what's available these days.

I graduated with a BS degree in the UC system and many years later decided to get another in the CSU system and even then there were difficulty getting transfer credits for base classes to get the second degree.
Santa Rosa Junior College[1]. I just looked up AMATYC rankings, and apparently they haven't placed since 2003-2004. I'm not sure if that's because of their math department degrading, or other colleges stepping up their game, or some failure at the state K12 level in supplying fundamentals (since the contest is based on student performance). It's possible my information is somewhat out of date (I went through there around 2000), but the first of my children will be making choices about colleges in a few years, and I was leaning towards recommending it (but haven't closely looked at it again recently).

From my experience at that time, it didn't feel significantly different than the campus I transferred to, except that the math classes at the Junior College were actually significantly harder, or at least more intense.

Good point, but if you make the comparison with the web, you can find the more popular pages using a search engine, and you can find those lesser known jewels by using services like HN :)
Dayton OH, no grants or anything. I've listed ITT on my resume, but never had a real discussion with an employer about it. They see Deans List (laughably easy) and just check their box. As the adjacent poster was saying, I may just leave them off future resumes, or put my degree as a footnote. Being a Web Developer for well over 10 years at this point trumps the value of any degree.

I think my only point was that it's _only_ value was what employers thought of them, which had a low rank on the value scale as it was, and now even that's gone. At this point I spent 40k for _literally_ nothing.
On the other hand, setting up https is a different skill set from the types of distributed systems that Umbra is trying to be, and I still find it to be confusing even though things like Let's Encrypt have made the process a lot easier.

Still, I've been around the space for a long time and I don't remember hearing too much about the Umbra project before today. That's usually a bad sign, especially given that they don't have a whitepaper.

There are a few major problems that slaughter projects like this:

1. They don't respect scalability constraints.

2. They don't actually understand what it takes to achieve privacy.

3. They don't realize that they've set up a centralized system.

4. They don't understand a lot of things about decentralization. This stuff is hard.

The only whitepaper I could find for the whole system was for ShadowChat, which says they use AES-256-CBC to encrypt the chat. AES is a symmetric encryption algorithm, and a strange choice for a chat protocol. Furthermore, CBC is not great at hiding patterns, and chat will often have a lot of patterns. Not necessarily going to cause problems, but it's another decision that I think is pretty weak, especially when there are better standards already out there.

As for anonymous cryptocurrency, there have been a lot of attempts at creating anonymous cryptocurrency and they are generally garbage. Either the mixing leaks information, or there is a reliance on central services, or other major problems.

Shadowcash claims to be a Proof-of-Stake cryptocurrency, which is a consensus system that has been pretty highly discredited among the more well respected researchers. The threat model is definitely different, and in general is a lot weaker both in terms of attack-resistance and in terms of decentralization that traditional Proof-of-Work. Even Ethereum has yet to come up with a Proof-of-Stake algorithm that they feel comfortable committing to, and they were so certain they'd get there that they added a feature which will break the currency unless they hardfork to PoS (at least that was the idea - given that PoS is not ready, they will probably just hardfork to a not-intentionally-broken PoW).

A few worth taking seriously are Monero, Zcash (though Zcash depends on new/fancy/less-trusted crypto - zkSnarks), and JoinMarket. Everything else that's got academic strength behind it is too early to have a user-ready implementation.

That's just my two cents. Maybe in a few weeks there will be a whitepaper that covers the full strategies of Umbra and it ends up being pretty good. But I don't think so, given that the few decisions that I could find already suggest that this is a platform built by amateurs.
We actually added a "optimize for size" flag pretty recently.
Not a specialist in the field, but I note the journal where both those papers appear, Medical Hypotheses, explicitly disavows peer review, and was founded by a fellow [1] who seems to have spent his entire professional life under something of a shadow. I'd take those hypotheses with a grain of salt. But, if I were feeling myself unduly miserable (which happens sometimes), I might also take magnesium supplements for a while just to see what effect it might have on my state of mind.

So many people using online advertising tools face similar issues. As many said here, setting the right success metrics + using the right tools to measure them is key for a Facebook Ads campaign to work well.

The first thing to understand is how different Facebook metrics are from your metrics.

Clicks on Facebook Ads are not visits, for instance, and the drop-off you're seeing is just normal.

Then, Facebook allows to track many events that can help you acquire the right people, including the one who stick, whether your product is B2B or C. There are 1.7bn people on Facebook, meaning getting the right ones is more than possible.

Experience is key, I work in the field and I can already tell you that your ad and bidding options were probably not good enough to get the right users. You basically asked Facebook to drive traffic to your website, never to generate long lasting customers... so to me, Facebook did what you asked for.

If you want to be successful on Facebook, you must use their Pixel, and optimize towards events that define success for you.

Place the Pixel on your site now, even if you don't plan to buy ads on Facebook right away. Set some standard events on key pages (e.g. purchasing a subscription or similar). This will help you for the next time, as you will be able to create lookalike audiences based on your best users. This audience, ANDed with some interests will allow you to target your ads to the right people. Combining this with a good ad, and a good bidding option (e.g. oCPM optimized towards subscriptions) will probably lead you to posting much better results on your blog next time.

This reminds me of a boardgame, played with 8 queens on a chess board, that was part of the National Mathematical Games Championship when I was in high school (in Portugal). It's called Game of the Amazons [1], and each player owns 4 queens. They take turns moving one of their queens to a valid position and then placing a stone within "sight" of this queen. Stones block cells and the first player to not be able to move any of his queens loses. Quite dynamic, and fun to devise successful strategies.

Cool paper by the way!

Non-stable channels get frequent builds, so it's not implausible it's a new binary.
The text writeup on the Alto restoration is now at https://news.ycombinator.com/item?id=12437018
The average branching factor for chess is about 35 moves, so verifying check would typically require looking at roughly 35 moves, while verifying checkmate would require about 1,225 moves. I'm surprised that a factor of 35 is enough to push it over the edge, but I guess Ethereum contracts need to be fairly limited.

I wonder if it's cheaper to verify a proof of checkmate that someone else computes. I'm not sure exactly what such a proof would look like, but there are lots of problems where finding a proof is hard, but verifying one is easy. Then you could make the checkmating player prove that it's checkmate and provide that proof along with their final move, and the contract could just verify it.

OV certs do almost nothing to prevent MITM attacks. Unless you expect users to recognize when an OV cert is replaced with a DV one.

Moreover, HPKP means that I have to trust my first visit to a site. Any new site could be MITMed. Heck, HPKP means that anyone that gets to MITM your domain can wreck it for however long a Pin is valid.

Startup Tech Stack Debate
Unfortunately in my case it was a private, non-profit university which had accelerated degrees (5 semesters squeezed into each year) - I'm rather dissapointed at how it turned out for the price (almost 50k!) and I wish i would have just put that money towards an actual, recognized university instead.

Heck, even last year I talked to another University to look into electrical engineering and only 1, ONE, class would transfer. All others wouldnt count because since they were a private school, their curriculum was different than most. Thats not something they put in brochures.
> Never mind pushy. How do rude salespeople even exist?

They exist because people who give in to avoid conflict exist, so pushy and rude both, in certain contexts and with certain target audiences, work in sales.
Commander William Adama: There's a reason you separate military and the police. One fights the enemies of the state, the other serves and protects the people. When the military becomes both, then the enemies of the state tend to become the people.
Being able to "level with someone" who is not like you is a learnable skill. Given the studied and demonstrable bias towards cultural (human culture, not "tech culture"), racial, and gender similarity when selecting for fit, not doing so, and contributing to continued disparities and injustices within this industry and society at large, is immoral and unethical and you should stop.

And it's foolish besides. You would "enjoy" talking to me, so long as I cared to play the game you want to play. There's no reason for that to continue once I've got the job (though at this point in my career I don't need to play your as monkey).

The third rail in these discussions is that, in tech, it is very likely that I also look like you and it is very likely that I speak similarly enough to you. I get a free pass for a lot of things from that. My lack of "culture fit" is by choice, because I think tech culture is a tire fire of gross mentalities and I don't mind criticizing it. Others have an uphill slog that is not of their choice.
Interesting article, particularly the economic details about why this train seems to be so expensive compared to high-speed rail in the rest of the world and the future-proofing aspects.

> I cancelled after one of the "professors" showed up hung over.

For the record, professors occasionally showing up hungover is by no means means confined to ITT. I went to a fairly good public university, and I had a few professors who came to an early-morning class obviously hungover once or twice (and 1 of them was a pretty good teacher). I'm quite sure the same thing sometimes happens at Ivy League schools as well.
This, too. Most startup compensation packages seem to be 20% (or more) below market rate + lottery tickets.
An update over the course of the previous 19 hours [1][2]; apparently that foreseeable future ended 10 hours after you posted this excellent reminder. They have begun closing [3] all outstanding github issues for v3 with the text:

Bootstrap 3 is no longer being officially developed
or supported.

All work has moved onto our next major release, v4.
As such, this issue or pull request is being closed
as a "won't fix." For additional help and support,
we recommend utilizing our community resources.
Thanks for your understanding, and see you on the
other side of v4!

Psychedelic experiences, like any drug experience are highly dependent on dosage, which is not standardized for Ayahuasca, as well as setting, and many other factors. Hence expect to hear a variety of experiences. It's generally gonna be quite a high dose of DMT from what I've heard so quite mind blowing.
Navy (reserve) vet here - I definitely agree that culture can be taught but unfortunately you have to find someone willing to learn. And unfortunately, most software developers aren't of the military "situationally adaptive" mindset but rather the "I'm a hot commodity where the hell is the ping pong table" mindset.

It's far easier for most young companies with ping pong tables to hire developers that like ping pong than actually endeavor to build a company culture and attempt to instill those values into their hires.
I don't know for sure, but I believe that memory addresses are generally represented as an unsigned integer of one of a few sizes. 24MB is well over the maximum value for a 16-bit integer (approx. 65K) so they simply used the next larger size -- a 32-bit integer (max size approx. 4B) -- and figured that most of the address space being un-mapped wouldn't be a problem. This is common in most computers because the allowed memory size grows at an exponential rate with increased size for the addresses.
This is interesting:

Craig: Had you and Jeff stayed close?

Shel: Not really. When he replaced me in my original job and I
was moved into the CTO slot, I was nominally in charge of
architecture, but in fact that just meant rubber stamping
projects that were 95% complete by the time I saw them. That
was all after having told me that my job was mine as long as I
wanted it. And I didn’t have resources other than myself to
work on anything I was interested in either. So I would say we
were not really on particularly friendly terms at that point.
It's too bad they never covered distribution in their original game licensing (that allowed publishers to get the Nintendo official seal on the packaging). I wonder if consoles/companies of today are correcting that to account for future distribution models.
I agree although some ceremony can add to your trip.
