Visual imagination
In short: my visual imagination is cheating, adjusting known pictures for every new description.

I read a lot of books, some of them are non-fiction, so I just perceive and justify models (e.g. psychological, economical, mathematical etc).

But when reading fiction, especially description of nature, cities, house interiors, I map the place author describes to some completely familiar places, using "nearest neighbour" principle. Of course, my brain slightly modifies that pictures, so from the long look they seem like what the author described. But it's not so.
I didn't seen medieval towns, and when reading about them, I imagine my own XXI-century town, just without billboards.

This is very sad. It highly reduces pleasure of such visual descriptions, and all I can get from the book are emotions, thoughts, relationships.

I tried to imagine not automatically, that is, to control the process and create pictures of really new places I've never seen, but brain "turns off", and the headache starts.

I have auditory type of cognition and not very good sight.

So what could you advice to develop better visual imagination?
the problem is that's already the case and the reason why HSR won't work that well in the first place.

imagine though that there's a fleet of self-driving cars ready to take you to HSR stops. best of both worlds?
That California business AMT ("franchise tax" of $800 a year, even if your business earns $0, or negative dollars, even if your business is a nonprofit) is a small business assassination program. I moved to California unaware of it, and was unable to migrate my non-profit to help fellow combat veterans with civilian reintegration, because the AMT was around my operating budget for the year. That's not a lot, but I can tell you that combat veterans have come to me asking for help, and I am unable to provide assistance except from my own pocket. California is infuriating.

I can definitely see a use for checking the integrity of the decrypted/decompressed data. Of course, implementation bugs or hardware defects could wreck your data after that stage, but increasing coverage can still help.

Verifying data integrity isn't exactly the same as authenticating a message, so I think you'd probably want to use a simpler scheme for that. For example, a basic CRC would suffice for most use cases there.
That's decades from being a substitute, and throwing more money at the problem seems unlikely to alter that fact.
This is nearly correct. Rather than the weight of air volume the cylinder could contain, you want the weight of a volume of air equal in volume to the cylinder (including its walls) -- and you seem to have the wrong sign on the measured weight and the cylinder weight. Your equation says that the measured weight is equal to the buoyancy force, plus the weight of the cylinder, minus the weight of the helium, which would be weird.

(weight of helium) = (measured weight) + (buoyancy force, which is the weight of an equal volume of air at the appropriate pressure) - (weight of cylinder)

We can 1) punish people who hire others to commit crimes for them; 2) punish groups of individuals for conspiracy.
Does supplementing this protein cause the brain to absorb it at the same rate as exercise? Doesn't exercise increase the brain's ability to absorb certain chemicals (probably a bad way to phrase it, mentioned elsewhere on this page).
How many highways run without subsidies?
HSR makes a lot of sense to me in general, but...

LA->SF is a terrible route because of geography. SF is northwest of LA, but the first thing the train does is head 50 miles East.

The quoted fares were laughable. The proponents were claiming the fare would be somewhere around $50 when existing San Jose->Sacramento service (a much shorter route) cost $40.

The insistence on running HSR all the way into SF is a bad idea as part of the initial plan. San Jose makes a better terminus: San Jose is served by Caltrain, Amtrak Capitol Corridor, and ACE, which provide connections to most of the Bay Area.

The plan should have started with an MVP and gone from there. "Merced to Bakersfield" is not useful. I would have gone with Los Baños to San Jose which could have served commuters. Then extend it to Merced and the rest of the Eastern Central Valley to help solve the Bay Area housing price problem.
Just to add some details:

- Static typing -- Type hints enable restriction of the dynamic typing behavior of default Python to mimic static types

- Type inference -- Not familiar with the particular behavior of type inference of Haskell, but yes.

- No JVM -- Definitely no JVM, but not particularly high performance so...there is that.

- Good pre-made web framework -- Lots of good ones, Python ecosystem is fairly rich in general, but ones I have used: Django, Pyramid, Flask, etc.
>We're already heavily subsidizing airlines to schedule flights to nowhere.

Can you expound upon this, or give examples of taxpayer dollars subsidizing flights to "nowhere"?
> And as of last time I researched it, a few years ago, there wasn't an HSR line in existence that didn't net revenue for the state.

There are only two HSR lines that are profitable (one line into Tokyo and the Paris - [edit]Cannes line). The rest are all subsidized include the Acela Express (search for all the references on HN throughout the years).

The US decided to build cargo rail which has given us part of an amazing logistic infrastructure. In other words, the US picked cargo over humans.

Exciting release! I played with the force layout on canvas to graph reddit conversations http://ramiro.org/tool/graphit/

It's harder to get interaction done with canvas compared to SVG, but for large graphs the performance gains are huge. Curious to dive into the other new features.

Thanks for this incredible piece of software mbostock!

Thank you, my only concern is for this new knowledge to be somewhat applicable. With Rails the upside was that I could do a ton of different small-medium-sized projects - there is always a place to spin up a quick Rails server to do some parsing / automate stuff.

If I try to pick something really esoteric I may end up not using it as much. What would be the most area of application for Prolog? I looked up the Wiki of course, but curious to hear a bit more casual perspective.

> with the price of air fares why would you not fly other than for the TSA?

1) You can't build airports in downtown cores, which unavoidably adds 30 minutes at each end.

2) Boarding an airplane with one door is intrinsically slower than boarding a train with many doors. Again, that adds time at embark/disembark.

3) Extra weight on an airplane inherently costs a lot of money, which means that trains will always be more spacious and comfortable.

I got so sick of Spotify randomly taking up 100% of a core that I switched to Apple Music. Yes, I actually found iTunes to be more stable…
When I see people talking about Closure, I don't see them talking about the power they get from metaprogramming. It's almost the opposite, people talk about the safety of FP, and power from Category Theory.

For C++ templates, you get that impression and multiply by a few googols.

Now, Ruby and Python communities do claim to gain power from metaprogramming. I can say that Python metaprogramming is something completely different from Lisp's one, but Ruby's is more similar. Yet, both communities put a hard limit on the amount of "magic" you should use on your programs (where Ruby's limit is way higher than Python's), so it can not become the panacea that it is in Lisp.

Metaprogramming is one of the main selling points of Lisp, the only other being how easy it is to implement. Other languages have other features to show.

HSR is California was always a bit of a gamble because there's three mountain chains to cross between LA and SF, which makes for expensive mountain crossings. But I'm perplexed as to why they're having cost overruns in the flat Central Valley.

After the NE Corridor, a Chicago hub network would make the most sense for high speed rail. The Northeast Corridor is already profitable (in isolation), but is also the best spot for HSR, so for another network one shouldn't expect profitability from day one.
I picked up Go a few years ago for my current side project. I have also been using it at my day job for the past few months. I have been able to improve performance on the order of 5-10x. In some cases I have beat out existing C++ code by 3x with care taken on the algorithm used.
Zend Framework 3 Released
The 2015 federal transportation bill allocates $48B to transit over 5 years and $205B to highways.

I've never understood why people frequently describe transit spending as a "government subsidy" but would never say the same thing about the much larger highway spending.

If you don't insist on adding tolls everywhere to make highways break even, why hold transit to a higher standard?
Un-peace in the Middle East comes as much from (IMO, inevitable) mismanagement by the British Empire ( and later the US ) as anything. Of course, the primary thing is the failure of the Ottoman Empire, with the death-blow by the Kemalists in 1920-1922.

There's literally a book - "A Peace To End All Peace" ( ISBN-13: 978-0805088090 )dedicated to numbing your brain with a thousand blows to show this.

Technology seems to be at odds with many people's sense of what is human and with human identity. It's a story as old as that of Captain Ned Ludd. I saw this very closely in my most recent gig. I put a (very crude) machine learning element into the flagship product and the reaction was a lot fear. Geez, I was just trying to keep operators from breaking (expensive) things. Again, though, the incentives were not with that. But the perception was "they're takin' 'er jerbs."
Trains allow more people from a more diverse spectrum of socio-economic conditions to work or live in and around an area. If you're a keen isolationist, whether for more or less discriminatory reasons, you almost certainly will vote to avoid useful public transport.

Besides, wealthy land owners have drivers on staff. Or don't have to commute to work on a schedule, so an occasional small ferry is good enough (cough... Marin).

It's all pretty awful, but not that hard to understand once you look at the more tacit end of public behavior.

You're really going to accept this version at face value? Seems like a hyperbolic description to me.
> It's ludicrous that we in this country can't have modern infrastructure.

https://www.youtube.com/watch?v=gkf2MQdqz-o is a survey of American domestic and foreign policy that goes into this question. The speaker is a distinguished US diplomat of the post-war era, who also served as Nixon's Mandarin interpreter when he first went to China. His short answer is that for interlocking reasons that make it hard to change, military spending is the only kind of stimulus spending that's politically feasible in the US, and infrastructure spending hasn't yet been able to break that lock, though it needs to.
With low internet speeds, lack of underground power lines, lack of public transportation, lack of walkable neighborhoods, and roads that have a lot more potholes/bumps than roads in other rich countries this makes me think we don't have modern infrastructure. We do have 6+ lane highways but....
It would only be twice as fast as current transportation, and if it succeeds it'll still get stuck in traffic, because a 5 person car with 1 person in it is a total waste of space.
If you are being active, you probably want to be able to do more. Move easily, see things, predict ahead, etc.

When you are not active, you don't need to be doing those things as much.

Or maybe people will just learn to exercise regularly and stay healthy? That seems more likely than the collapse of society.
And the documentation is good too! (And that means that it's good, not like most software with "good documentation" where "good" means that it has reasonable feature coverage.)
Trains are are a commitment to the long term future. To me they are visionary in the sense that they show confidence in stability and continuity that extends over multiple generations. Whether big engineering of this kind is actually the right choice or not is another question that I cannot answer. But I would be sad to think that America (and I'm not American) didn't have that vision any more.
Hello, just put up this quick walkthrough on how to use a native library with Amazon Lambda. Any feedback or suggestions would be greatly appreciated!
The route is a pretty poor outcome of special interests. I recall reading that the best engineering firms in the world said that we should essentially have a hub and spoke approach (i.e. you have a very straight high-speed line from LA to SF and then you have spurs that connect all of the small towns to that main pipe). Instead, the route curves around to get to every small town that wanted a whistle-stop.

I would personally love to see high-speed rail. SF->LA feels better to me but your observation that San Jose is connected to the bay area already and makes a great terminus is really good. Plus, I live in Oakland so I'd like it even more if it came right into my backyard :)
"small business assassination program"...

Thank you. Thats exactly what I would classify it as. Drown the startup in a bathtub (using a bit of Grover Norquist rhetorical flourish there). I am just not bright enough to see what the upside of this fee is, especially in CA which I thought was a business/startup friendly state.
"Relative obscurity" is a matter of perspective. Within my fields, I'm far better known than Drew.

And that's the key difference here -- we have both been very successful in doing what we want to do. We just want to do different things, that's all.

I have tried using the parental controls on YouTube, but stuff always seems to slip by with the recommendations they show on the side bar.

This allows me to keep out unwanted videos but still offer some learning opportunities.
German here, what did you just say?!/s
If a state or national government in another first-world country had decided to build a high-speed rail system in 2008, when California did, they would have made significant progress by now -- they might even be operational on part of the line, or even all of it.

When the richest country in the world can't get this kind of infrastructure project off the ground, it's a sign of serious dysfunction. There are way too many interest groups that are able to block development of infrastructure and housing projects in this country.

I find learning a language (syntax, constructions) easy. What is hard, is learning its ecosystem, good practices, gotchas.

In this sense, a totally new framework / ecosystem for a known language is as difficult as learning a new one.

Is Bosnia considered Western? Genocide there in 1992-1995.

On a road trip, a Serbian in-law had us stop by this beautiful bridge in Bosnia. Built in the 1500s with Ottoman architecture, which is odd for that area. I took photos there, smiling and having fun like an idiot. Only after leaving and checking wikipedia on my phone did I see that the relative failed to tell me about the massacres that happened there by the Serbs. Women, children, rape, etc.

If I remember my finance right you never want to use your option until the very end since baked into the price of an option there is a premium for time which decreases the closer it is to expiration. That is why black sholes works pretty well.

Generally, proteins you eat get broken down by the digestive system into their component amino acids. There are some notable exceptions where proteins can apparently get absorbed intact, but generally proteins are broken down upon injestion. Supplementing intra-venously might be the only option.
The facts on the ground suggest that Google does not have trouble delivering high-quality software, so your arguments aren't very convincing. To me the biggest issue is that their customer-facing software is often not what people want, but that isn't really a development process issue.

Well the scenario I'm envisioning is that sign-then-encrypt guarantees that no signatures were stripped off in transit, that's all. It prevents people from saying that an encrypted message (which they were unable to read) came from them, even though they didn't encrypt it.

I think it's probably most important in trust on first use scenarios, where an MITM in position during trust on first use can strip off a plaintext signature and re-sign the encrypted message with their own key - if there's a signature inside the ciphertext that matches the signature outside, you can detect something like that.

Not sure that it really comes up much, though.

Yes, pretty much what I was looking for. Although I personally wouldn't use that just because of the design. I also use that hackerish "homebrew" optics for my terminal, but I actually can't get used to it anywhere else than in there.

However, I guess I have some minor differences in mind (like a different layout and other voting system), but it's probably not enough to justify the creation of a new tool.

I love that you suggested YNAB here but I have one significant problem with it that doesn't have a consistently good workaround.

Reimbursements.

When I m out with friends and the restaurant doesn't split the bill I'll often cover it then get paid back with cash or PayPal. YNAB doesn't seem to handle this very well.

Then wirh longer term reimbursements it gets worse. Either you forget that you are owed or you float the debt.

I still recommend YNAB. but that specific problem means it's not on my "reliable" list.

Varoufakis[1] and Blyth[2] argue that it might be impossible to create models of the economy. They both warn that there is a seductive quality to math, but that "elegance" is an oversimplification that can easily unravel when given the chaos of the real world.
