It's not just about confidence though. Yes, for some people, the question of whether they're a good enough programmer might stem from (social) insecurity, and I think what you're saying might be a very good answer for them.

But others, including myself, ask the question because we want to, as you say, 'always be learning'. We might be insecure, for example, about getting stuck at some equilibrium that isn't optimal, and just fishing for where to go next.

For example, it was through similarly-themed threads on HN that I learned about functional programming. I learned how important immutability might be, and to try and keep my functions and methods pure, even if I'm not going all in on the functional stuff.

Hell, even just thinking in terms of separating data from code was a revelation that I might have missed without HN functional weenies constantly submitting articles that boiled down to that as a point.

Anyways, not disagreeing with you necessarily, just nuancing.
I keep seeing the fallacy that all currency value is based on future expectations.

Here's a thought experiment... in the US, work full time while getting paid in Bitcoin. Make all transactions in Bitcoin. At the end of the year you'll need to file a tax return. Your final options are:
1. Buy some USD to pay your taxes.
2. Go to jail.

Demand for fiat currencies is ultimately underpinned by them being the only instrument accepted for payment of taxes.
Compared to changes of traditional currencies, two years is incredibly fast.
Rule of thumb is that the Santa Cruz mountains are green and the East Bay Hills are brown. When I moved to the Bay Area, I was taught that this is how you orient yourself: if green is on your left and brown on your right, you're going north; if green is on your right and brown on your left, you're going south; if you're driving toward brown, you're going east; and if you're driving toward green you're basically in the mountains already or on one of the bridges.
This is one of the worst article I read in a long time - also I couldn't disagree with it more.
I like eating salads and my friends like eating stakes - Venmo and Square Cash makes it so easy for us to spend time together and split money in a sensible way (how splitting it in a half would be sensible in this case?). Saying that this make friendship transactional is just bullshit - it makes them honest. And people thinking they they are charged for friendship because they have to pay for their own meal need to rethink it.
Not in my neck of the woods. If you sent a Venmo request amongst us you would be invariably called an asshole (and it wouldn't be a kind way of saying it, that sort of thing is real shitty). We use Venmo to push money around (Square Cash is nicer, but that ship has sailed), but it's more like "ehh, $25 is about right and I'll get it next time so the rounding will work in my favor".

We are not doing down-to-the-penny nonsense because that would be silly and we are not dunning our friends because that would be awful.

Most people in California don't realize that the air quality in the San Francisco Bay Area is actually worse than in Pittsburgh [1].

Moreover, after growing up in Pittsburgh and living in Seattle, I can tell you that Seattle definitely has less sunlight (it's not even close) than Pittsburgh. So much less that my doctor had to prescribe my Vitamin D to address a deficiency I had when I moved there (after living in Pittsburgh my whole life, no problems).

If your entire economy has been based on consumer spending for decades and you decide to incentivize people to save instead of spend, you basically just destroyed your own economy. Maybe it's theoretically possible to restructure the economy first and then switch to hard money, but you haven't proposed how to do that.

If you save money by investing it, it does increase. Only if you save money by hoarding it does it just sit there.
The Tail End – Wait but Why
I wonder if these could be used to produce panels on a remote planet/planetoid. I.e. could you use this to create a bunch of panels to place on the moon, even with the low efficiency you'd still save a lot by not having to ship them.

Yeah. Even in the UK - which is behind much of continental Europe in terms of banking - you can send money to anyone's bank account immediately and for free given their account number. Neither of these things are true in the US (at least going via the bank, hence why Venmo / Square Cash / etc exist).
I wonder how it compares to Threema. Signal's servers are located in the US, and the service requires you to provide a phone number, which is a deal breaker for me.
When I spend more at dinner, I eyeball the cheque and ask for a little more to be put on my card. If we're alternating between who picks up the tab, I'm mindful about buying them drinks. Venmo just makes cash-only, "no more than 2 cards" dining and vacation booking easier.

Note that I've had friends try to split bills to the penny. I tell them to stop, because both our times are worth more than that. (The exception being if I know they need the extra cents, in which case it still seems more reasonable to round down in their favour.) That kind of gentle social shaming is productive and something I've noticed a lot of people my age shy away from.

TL; DR If you think Venmo is ruining your friendships, it probably isn't Venmo.
What if you just happen to enjoy steak and your friend enjoys chicken? Then in the 50-50 split, you could be seen as "abusing" the system if you two go out to dinner often, yes?
Thank you for these links
I think it was 50/50 even though initialy I thought that the front end would take longer since I wanted to just use the bare minimum features from Vulcan.js.

Since Vulcan is still an early stage project there were (and still are) some stuff that I needed to change also some stuff in the backend.

Also - there were some problems with the DNS records and almost a day was spent working on it.
If you have more money or simply don't mind spending a lot on them in restaurant, then this strategy forces me to pay way more then I would otherwise - while I get nothing in return. Well, except socialization which is worth something.

But I still like splitting check much more. It allows me to spend/not spend how I want regardless of whether I am least or most willing one to pay for more expensive things. If I drink/eat a lot I pay a lot and I don't have to feel bad about somebody else paying it. And if I want to save money, I don't drink and don't have to worry about friend eating a lot.
Really? I thought it was the 2nd incarnation of the Klan that was known for anti-Catholicism. I thought the first incarnation was basically pro-Confederacy terrorists who probably cared little about Catholicism.
In my extensive work travels over the last decade I was surprised how many do not for reasons other than ignorance. In the US, the ISPs explicitly & implicitly denying tethering usage made for a very confusing time late 2000's/early 2010's. When VZW(and the other big 3, I presume) gobbled up the smaller competitors they banned tethering, then charged extra for it(after or until the toothless FCC intervention?). Masking user agents, creating on-site APs out of old linux laptops+Mobile Data USB and the flaky USB data port enabled routers worked around these restrictions well enough. Have these policies been changed by the providers to where it is simple for average users w/out system tweaks or custom ROM features?

The fun thing there is that other than photovoltaics, maybe (I don't personally understand them well enough to say for sure), the other two alternatives you are mentioning are also "nuclear -> heat -> mechanical force -> electricity" chains :)

Is just that some of the infrastructure is pre-existing.

This assumes you want anything to do with the front end :).

Maybe a better tact at why JavaScript first: people are far more likely to hire junior front end people than junior backend.
I'm with you. Even without the factor of not being able to afford it, isn't having autonomy over your own purchases and finances a good thing? It's not 'cheap', it's responsible and avoids money getting in the way of friendships.
Seattle is shown to be even worse in the winter months than Pittsburgh on that chart.

Ignoring the specifics of my examples, which really aren't important, the problem is the frequency with which these process failures happen. If the board is in a near-constant state of mayhem and flux because the sales director makes a list of "super urgent" bugs that have come out of a client meeting (because, of course, categorisation of bug urgency is not something mere mortals can really handle - everything is always urgent) and the art director has suddenly decided to make another list of visual flaws he's spotted, and so on, then no one can really get anything done because it all surprisingly quickly turns into a mess. I find Trello enables this sort of behaviour because the barrier to entry is so low, and I say this because I've seen it happen several times.

As I said upthread, Trello is adequate if you've got a project manager vigilantly pruning the board - but if you have the resources for a project manager able to do that, then why not just get them to use something that's really much better suited to the purpose?

Anyway, this is just my opinion based on my experience. Trello is a good tool for certain things. I don't think it's a great tool for managing a software project with a team of more than about three people, and even if you can make it work, I think most teams would really just benefit from using either JIRA or equivalent, or maybe GitHub Projects (which I haven't tried, but it looks quite good).

Thanks for your reply.

The best bootcamps (in terms of placement rates with SV companies) are equivalent to 12 week long interviews that the interviewee pays for.

They screen for people who already know a good bit, and are really good at interviewing in general.

Then they put those people through an intensive 3 month long coding interview and place the people who make it through.

The problem with this business model is that there is a small supply of people that are capable of making it through, are willing/able to pay $10k+ to do it, and are willing/able to go 3 months without pay.

It's a joke to think that Joe JobChanger is really going to pick up all the skills and knowledge he needs to get a job at Google in 3 months.

Professional programmers with years of experience regularly spend that long just practicing white board problems to get try to get a job at Google.

The amount of students who can do that is just too small to build an industry around.

I am categorically not interested in the idea that freeways cost too much, because public transit (at the level of speed, frequency, capacity, and comfort that would be competitive with driving) also costs too much.

>It also helps shift the balance between denser housing, vs. the sparse housing available if everyone assume there will be fast transit.

This is a fallacy. The limitations on housing density are driven by residents of the urban core and inner suburbs. It doesn't matter to them how bad transportation is for people who can only afford the outer suburbs. Increasing the pain of living in low-density outer suburbs will not create more housing in the urban core and inner suburbs.

Just seems like part of an evolutionary process. Very rarely is software released where version 1.0 is perfect. Maybe if government currencies allowed for these things, they would also be better by now.

This is part of the reason why bitcoin remains highly speculative. People point this out like it's a bad thing - the only people who have it are just investors, speculating. But this is part of the process that bootstraps bitcoin's value, so that when it does become more practical to use, actual value is being transferred.

The fixed supply doesn't really make sense if you want BTC to function as a unit of exchange (rather than a commodity). I won't go in to the reasons why since they have been elaborated on by many other people.

However, the fixed supply does incentivize holders (ahem hodlers) to increase the value of the coin - whether that is by starting companies that use BTC, spamming HN with BTC/Reddit related posts, etc. It's an interesting way of arranging a bunch of people in a sort of distributed boiler room.

That said, once the mining subsidy completely ends (assuming BTC is still actively used then) its possible we will see some calls to increase the supply. Otherwise the transaction fees will need to become huge (or the price will need to rise 1-2 orders of magnitude) to support current levels of mining activity.

This (widely disparate eating patterns between friends) used to be a problem, but then we hit on a solution: at the end, when the bill comes, each person adds up what they ate/drank, and adds 30% to that (which covers the tax + tip). Some items can be ordered "for all", and the persons who did that take ownership of those too. It's worked beautifully so far.

I'd agree that Californian snow-driving skills are a joke, and that Tahoe isn't actually that difficult compared to New England winters.

However, there really are terrain types that CA has (and Google tests its self-driving cars on) that just don't exist back east. There's nothing like CA 1 on the east coast, with windy 15mph switchbacks and a sheer several hundred foot drop into the ocean if you miss a curve. Nor do they regularly have to deal with the road being closed because of rockslides, or Tesla drivers who pass you illegally.

It's more of a consequence of an absence of policy (like with net neutrality -- nothing stopping ISPs from traffic-shaping and restricting content without "regulation" of some sort) than the presence of one.

Employers are free to impose whatever restrictions on "moonlighting" they want on their employment contracts (and tech's routinely non-unionized workers are put in a position where they have no choice but to accept them)

California actually has laws in place that make it illegal for employers to do things like add non-compete clauses to their employment contracts (and these laws also render said clauses to be unenforceable).
The same and possibly much more could be said about Syria and Russia. Remember in the early days of the civil war when ISIL had just entered the Syrian theatre and was capturing territory? Back then ISIL seemed to target anti-Assad areas more than Assad.. Rebels would complain that the Syrian air force would soften rebel targets prior to ISIL assaults. In fact, look at who has benefited the most from the rise of ISIL, i would argue it is Assad. The west and Turkey have almost completely abandoned their mission of deposing him because of ISIL. Also Russia has hardly done much against ISIL (much less than Turkey it could be argued). But nobody talks about Syria (and by extension Russia) supporting ISIL.

I see where you're coming from and i admit there seems to have been murky dealings on some level between the two, but I think whatever connection may have existed between Turkey and ISIL is overstated. Undoubtedly Turkey's past open border policy had been used by ISIL, buts it had also been used by the other rebels and even the Kurds and western govts like the Americans. Also Turkey has other better client groups to do their bidding; in fact groups like Nusra front and Ahrar al sham have long been giving the Kurds a hard time. And unlike ISIL, none of these other groups have ever attacked Turkey.

Ask HN: Marketing hacks for techies
Hi,
I know that I personally suck at marketing. I also know that there are quite a few Show HNs that have so much potential but just remain undiscovered because their creators where not marketing gurus.

Do people have any ideas for marketing hacks for techies?

Other than paying for Fb/Google ads or show HN.
That would put them at 20-30 watts-peak per square meter, or $0.50 to $0.33 per Wp if the cost is $10/m^2. At the lower efficiency, crystalline silicon modules are already cheaper. At the higher efficiency, it may be cheaper than crystalline silicon modules but just slightly. It would need to reach commercial-scale production very soon to avoid being overtaken by the relentless manufacturing optimization of standard c-Si technology.

Another problem is that "less than $10 a square meter" is almost certainly an estimate referring to scaled-up commercial production. Printing 100 m^2 of devices for that test site did not cost under $1000.

Finally, I'd wonder about lifetime and endurance. Crystalline silicon itself is extremely durable. With good supporting materials and thermomechanical design, c-Si modules can go 30 years before they degrade below 75% of original rated output. (There are at least a few solar modules installed in the early 1980s that are still working fine.)
> genetically engineer some photosynthesis in to skin

The "infrastructure costs" for making that possible will probably outweigh any benefit, unless you also genetically engineer people to be immobile brains connected to bat-wing-like collection surfaces.

Even with energy-conversion inefficiencies, it makes much more sense to construct/build something big and immobile that indirectly collects that energy which we can then tap.
I think for some parts the problem is not really specific to tech people. It's just very difficult to integrate milieus that differ that much in income. People living on six figure annual income just have different needs than people trying to get by with magnitudes less.

When I did not had much money, I consistently prefered cheaper option. 50-50 would mean that either my richer friends can not eat what they like due to me being there or I can not socialize with them as often. Alternatively they could pay more often, but it would be hard to keep that fair and I would not like leaching off theirs money either.
I'm also thinking of the Virgin River Gorge on I-15 in Southern Utah, which isn't just steep and winding, but also extremely narrow and windy, and yet supports interstate speeds.
