Have you ever met people with children?

Generally, strict hours enable simple, well-defined coordination with others. You often _need_ that kind of agreement when others are taking care of your children in your behalf, e. g. schoolteachers, partners, grandparents.
I know too little chemistry to say if this is viable or not, economically speaking, but here are a couple of questions that I have:

- ammonia/NH3 is highly corrosive IIRC, and also toxic. Do we have good ways to handle it in a safe manner?

- while capitalism has its drawbacks one thing it usually manages is to get funding for anything that seems like a good investment. And while I can understand why Exxon or Shell might stay clear there are many more who doesn't have their own oil fields and should be happy to get on the next big thing?

Don't misunderstand me: this sounds extremely cool and useful, but those two questions immediately crossed my mind.
Roger Gordon (http://www.greennh3.com/) has a design for a small-scale ammonia production system that individual farmers could drive from their own wind turbines. It produces no methane. He has not found investors yet.

Driving these big polluters out of business would be a great service to the world, and could be profitable besides. They don't just leak methane, they also release huge amounts of CO2. They have no reason to leak methane; it even costs them money. They are just sloppy.
How are you handling the data? I see your just asking companies to email you, but then somehow you have positions - do you pull them automatically or do you process them by hand?

I ask because we just finished a job round, and it was so annoying posting our job on all the specialist job boards that apply to us. Every single one had a different enough form that I had to spend time working out how it would be displayed, what went where, dealing with the various problems (eg, we offer full time and part time and the number of sites that make you choose one was frustrating.). I would love there to be a standard data file format where I could have written up our job once, then just uploaded the same file/URL to each job site.

That said, well done for starting this and I wish you luck in tackling this problem.
FYI, purchasing with a credit csrd likely extends that by another full year, if not two years. Check your card benefits.
Surely this would be an energy storage option, rather than a generation option.

You heat up water during the day, to generate electricity at night.

Aristotle’s work (or rather the work attributed to Aristotle) has survived,[0] so you can read it for yourself.

It allows you to connect a private network to any other network, including the internet, without allowing hosts on that network access to hosts on the private network. It’s a form of access control. What is your justification for saying that access control measures are not security controls? That is so incredibly contrived.

"England's got a new Queen" seems to have 1.5m views - how is that a more popular search term than "richard nixon" or "marilyn monroe"?

I can only assume it's some kind of google suggested term after people type england, and then they click on it thinking it's breaking news ...

But it seems a weird outlier
If anyone is interested in what could happen during an actual nuclear war, I’m reading a novel on the subject called Arc Light by Eric L Harry.

It’s quite good so far. Weirdly terrifying, given that the action and writing is so clinical. So far it’s just fairly plain events. No drama or tears. And yet... terrifying and somehow moving.

> And yet we’re made to swallow the fact that he’s an exceptionally good person

Are we? Wolfe has stated in interviews that Severian is not supposed to be seen as a good person, but rather a deeply flawed one.

> an amazing leader whome people follow with no afterthought

Severian only starts to draw a following once he becomes autarch, and then people aren’t following him as much as the office (or the effects of the office). Elsewhere, it is Severian who tags along with various people he meets.

> the Chosen One who brings the era of the New Sun.

Did you go on to read The Urth of the New Sun? I won’t spoil it here for others, but that book does reveal that Severian’s “chosenness” and “saving of the planet” isn’t ultimately all it was cracked up to be.

As for lack of character growth, it is strange that you list Dorcas an example, because IMHO her gradual development over books 1–3 (with the coda in book 4) is a poignant aspect of the work.

And incidentally, novels where a protagonist tours a world full of odd characters, and the author does not particularly develop these characters or even the protagonist, is a well-established literary genre that goes back many centuries (the picaresque).
It's worth checking that claim against the Ninth Circuit's decision [1], because the court said:

> We emphasize the narrowness of our First Amendment holding. We do not hold that all software is expressive. Much of it surely is not ... We hold merely that because the prepublication licensing regime challenged here applies directly to scientific expression, vests boundless discretion in government officials, and lacks adequate procedural safeguards, it constitutes an impermissible prior restraint on speech.

> Also, I'm sure plenty of people at NASA and other space agencies have thought of this, and there are probably some good reasons for not doing it, but why not take some deep core samples and look through them with a microscope for anything moving?

I would guess the difficulty of taking that sample would be one reason - in particular, the difficulty of building, shipping and operating necessary hardware. The best we've done so far is AFAIK the 5m thermometer-tipped drill on the Insight lander, which drilled ~30cm down and broke. We really need cheaper access to Mars for such missions, so that we could send more and heavier hardware for less.

The linked source is directly from Adobe and directly contradicts the claim that "you need 13.1 to launch in 64-bit."

The source says:

> Photoshop CS6 and CC only install a 64-bit version on Mac OS.

Further, it says:

> Photoshop CS5 installs a version that can launch in either 32 bit or 64 bit when you install on a 64-bit version of Mac OS (Mac OS X 10.5 or later).

If CS5 install can launch in 64-bit, it wouldn't make sense for CS6 to be 32-bit only from the first version.

Even further, I know from personal experience that your claim is highly unlikely. This is a screenshot of Photoshop CS5 (12.0.4) running in 64-bit on my machine (High Sierra). Noticed it says "12.0.4 x64."

https://imgur.com/a/nCTghcy

I am not sure of the source of your information, but it's simply incorrect.

Edit: This is another article directly from Adobe.

It says:

> On Windows, both Adobe Photoshop CS6 and Adobe Photoshop CS6 Extended have the option to run natively in either 32-bit or 64-bit editions. On Macintosh, only a 64-bit edition is available.

I disagree. A lot of those pdas were very expensive already. They just weren’t good enough.
Why Is Ruby Slower on Mac? An Early Investigation
The goal I believe is to be 1:1 in multiple currencies (or maybe 0.9:1 or 1.1:1 as close as possible -- so if you were to buy libra with japanese yen it would cost 1:1, or possibly they'd do it based on the highest of the pegged currencies, so if euro is highest they'd go w/ 1:1 euro, then when you cash out to usd directly from libra, you'd go off the current euro:usd differential.

It's definitely complicated, and I think going to be a management / development nightmare. The best thing would've been just go with USD, or Euro since those are the most used funds currently then have a built in forex exchange to instantly change local currencies to libra based on their usd/euro pairing rate.

Many California municipalities mandate a certain number of parking spots per housing unit, and also restrict the height of buildings. These laws act to reduce housing density, so that owning a car is required.

> It allows you to connect a private network to any other network, including the internet, without allowing hosts on that network access to hosts on the private network.

I am not saying that. It simply isn't an access control measure.
I'm sure there are people in Japan that are dishonest or forget, or get sick and don't come into work on the relevant day.

The app possibly could handle most of it, there surely has to be a point somewhere where the decision to share the room has been made, but hasn't been formalised yet. There may be a system where it requires both of you to agree to rent the room, so you aren't left with an unpaid bill, you may be left without a room that you needed though, which may be worse.
I didn't read it as saying car free living was illegal, rather that city planning laws make it impossible to achieve in practice. But it is a bit ambiguously phrased.

I thought in 2007 and I still think today the fundamental reason why there was space for the iPhone to be the phenomenon it was is that
1) The success of the iPod let them dictate terms to AT&T and get subsidies no one else could while keeping the customer experience clean in a way competitors couldn't (US phones had an unbelievable amount of crapware in the mid 00s, including great ideas like flashing the firmware to prevent camera phones from transferring photos over USB and forcing you to use a carrier service that covost $1/photo)
2) Microsoft's antitrust hangover prevented their mobile department from strong arming carriers earlier on

Microsoft's real mistake post iPhone release (and definitely post Android release) was not immediately making Windows phone free, OSS would have been nice, but I think most manufacturers moved to Android as their flagship because they got it free.
Almost every platform seems to have believed in web apps at some point. Nokia did an attempt with Symbian, Palm had WebOS, Samsung tried that with Tizen, Apple with iPhones, Microsoft for Windows 8, Mozilla's Firefox OS...

I'm sure I forgot a few. All attempts failed quite completely.
> that anyone who wishes to use violence legitimately (aka legally) must get permission from the monopoly holder.

Yes, but then I kinda fail to unambiguously see what you mean by "unsavory" - if these groups are successfully regulating the use of violence within their territory, that means they're providing the most basic function of a state. It just seems to be a fact about society that new states originally get started mostly when "roving bandits" start providing basic security within some stable territory and thus acting as "stationary bandits". It's not that clear why the fact that these groups are "unsavory" should be an obstacle to acknowledging this dynamic.
The origin of physical currency -- coins -- happened 2000 years after money was invented. Coins were invented as a way to provision armies.

It worked like this: soldiers were paid in coins. Taxes were required to be paid only with the new coins. The only way to get the coins, to pay your taxes with, was to sell supplies to soldiers who had coins. Armies supplied, check.

Facebook has an opportunity to force its coin into use by a similar stratagem: offer advertisers a discount (at first!) if paid in Libra. Advertisers can only get Libra from Facebook account holders. Advertisers have to sell at a discount, for Libra, to get enough Libra, but they get it back in the advertising discount. If buyers want these discounts, they need to get Libra from Facebook.

Soon, Facebook controls the economy of the world.

It was recently explained to me that Facebook only wishes they could be as evil as Google, but they were way behind. (Google passed Microsoft sometime back.) This could leapfrog Facebook far beyond Google's dreams.

Are we in for Dystopia? I can't see how not, unless they fuck up so it's both too hard to use and too easy to get ripped off.
The Viking landers era was different. There was money for space exploration. Nowadays, space missions need to continuously prove their value, which I think changes how they're presented and ultimately their mission profiles.

You send a probe to find life, it found no life? No money for the mission ops next year, cut the comms and go do something else. You send a probe to perform scientific measurement around life-bearing capability past and present? You can exploit the sunk-cost fallacy to request ops budget year after year, because it's now hard to just cut people off from a firehose of sweet science data. "Look how much we got for X$, for a few extra Y$ we can have a whole year more of that!".

> Sure I see how simplistic social and web news has made things, and the promotion of minority views, but did we really descend that far into the Idiocracy? :(

I think the truth is closer to "individuals are smart, societies are dumb".

More interesting question to me is why the hell some firmware boots take so long now. I know laptops from years ago much, much faster than what I have now, which is otherwise much faster than them. And the firmware initialization times for some servers I've seen seem completely obscene (on the order of minutes).
THANK YOU.

I’m not enough of a dinosaur to need this yet, but this is the right approach. Advertise willingness to hire regardless of age, which works to ingrain acceptance in your own company, and shame those who don’t participate.

This is just what our industry needs.
I've been a professional developer since I was 13, in the sense that was when I sold my first commercial product, some 36 years ago.

I've gone from being the wunderkind to being the over the hill grey beard, and I've seen some shit.

What I think happens is that every 4 or 5 years, there's a cycle of devolution. The new kids in school want to be that wunderkind - they choose therefore to ignore the wisdom of their elders and forge ahead into the darkness of their own knowledge with the light of their own hubris to guide the way. Many times, this is more than enough to build something great - often though, it results in failure.

But, every year, a new round of developers hits the scene, fresh from boot camp. These bring new (old) ideas to the scene, rebranded perhaps, refactored perhaps. This somehow has a devolutionary effect on the industry as older developers get moved off the production seats into management, and there isn't an effective turnover to the new guys, who then spend a few years re-inventing things and re-gaining the experience of the previous guy.

Things get re-invented. Regurgitated. Recycled. Eventually, a kind of stability occurs - and the new programmer becomes the old guy. The seats get changed again, and we go through the cycle again.

Oddly enough, as someone who has gone from being the 13-year old wunderkind and is now the near-50 old guy, the only way I've found to survive this cyclic regurgitation is to stay focused on the user.

Nobody cares if the user is young or old - what matters is if they're using something you built.

Ageism is real. I started my career with a healthy dose of it - although in the 80's it was a lot more common to have respect for ones guru's than it is today, I nevertheless didn't want to know a lot of the 'obvious' wisdom of my elders - and now I'm 10 years away from retiring from the career, seeing it from the other side of the fence, there is a great deal of 'obvious wisdom' I see the youth of the technology world today clearly ignoring, and pretty certain they're going to re-invent in a few years time, subjectively and objectively.

In my opinion, ageism happens because its hard to train people who have just escaped the hell of modern education, and all they want is the freedom to apply their skills and develop themselves, and their identities as skilled workers. Its hard for an old person to care about the stupidity of youth, because after all - if you've got the experience - you probably had a healthy dose of it too, and well .. you came out okay right?

If we want to deal with age-related complications in this industry, we should address the source of the problem: educating people, and being educated by people, is hard.
Nikon's Small World competition winning entries
Unlikely. Probably representative of not much even if there were. Most old types like me would not seek to be a visible statistic if they couldn't find work, but quietly go off and find something else to do.

Of my similarly aged friends who were once in tech, most have now left it - some from getting bored or burnt of some aspect, others from ageism. It's an absurdly ageist sector and startups an order of magnitude worse. Worse still I have seen overt and blatant ageism on the hiring side multiple times.

Not everyone cares, and you can often work around it with even more applications, but it does get tedious hearing the euphemisms for "ew, you're old, we're all cool kids." that can translate as "You're perfect, but we think you'll get bored", "great interview, but you're a little overqualified". Hmm. My qualifications were on my CV when you invited me...

I've yet to fail to get work, but it's definitely becoming more effort.
At the office I worked at that did this, there was a docking station with two monitors a keyboard and a mouse permanently at each desk. So you could, in theory, just plug your laptop into the docking station at any desk and start working.
Ask HN: Know any websites/weblogs that explain math/ML intuitively?
I'm a huge fan of learning things intuitively. A while ago I stumbled upon http://betterexplained.com, but apart from that, I haven't seen any other website/weblog that explains math concepts intuitively or with diagrams. I know a couple of YouTube channels but I guess I'm not a learn-by-video type of person. Do you happen to know any relevant sources that don't just explain the formulae, but rather explain the thoughts and intuitions of mathematical/ML concepts?

Sure I can set up a "basic" VM with several services that have to be configured and maintained just to have this one feature, but why bother when this service and several hosted alternatives provide it for free?

One basic VM for mail, another for DNS, another for something else and soon you have a shitload of VMs, some of which are likely misconfigured and security risks.

Actually no, there is lots of tech to stop ICBMs, in launch, orbital and re-entry phase.

While degrees are not required for doing a good job It is also likely you would not go to a doctor without one, A organization is interested in accountability degrees provide that validation to some extent.

A degree does not mean anyone is fully qualified for a job just as not having a degree does not mean he cannot do it. The damning part in Equifax is that CISO did not have any prior experience in this domain (likely your friend has worked as developer before)
