> The latter leg is still pretty close to "populated areas" (just outside various towns along the route), but the track was specifically made for that train (taking required minimum curvature etc into account) and point-to-point connection (fewer junctions).

How many grade crossings are there on that route? This train, at least through Hallandale/Hollywood, needs to deal with a grade crossing every half mile (800m) or so. Considering the crap that went on during the effort 20 years ago to get FEC to stop using horns at certain times of day convincing people that a train should be allowed to do 100+ mph down that line is a non-starter.
That's still a local phenomenon though if the numbers were even big enough to make a big difference in traffic and pricing.

Completely the opposite for me.

At least booking.com allows reviews only when you booked. And when I read the comments most point out real problems or benefits of the different housings.

AirBNB reviews on the other hand are painfully useless.

And Google is the worst, with a shitload of review from people that look like that probably didn't even went to the place, or just disliked being denied on a discount of something, so you jget useless 5 stars review that say "best food ever" and 1 star reviews for "super rude server, worst restaurant ever" for the same average restaurant, and nothing in between to tell you what the place actually feels like or what food is good/bad there.
I'm not an economist but I'm pretty sure that the price of housing is determined by supply and demand.

Wouldn't housing be more affordable if more houses would be allowed to be built?

Cities seem to enjoy banning people from using their own property as they deem fit. Instead less bureaucracy with faster and cheaper costs for building housing would curb this phenomenon at the roots.

This doesn't solve issues where there isn't enough land (like an island) but in most cases it should work.
Five years ago I had a phone with buttons and rarely had to stop the impulse of trowing it into a wall because google kept installing updates to apps I don't want and can't do more than factory reset.

Sure, I didn't have a fancy app to look at the timetable for the bus, but there was a wap-page I could use and frankly the apps are about as frustrating but now because touch interactions so often go wrong without real buttons.

And I use both vim and ssh daily, rarely wishing I had an new app to replace them with.
Some people are naturally early birds. Either by long ingraned habits. I used to get up fairly early without an alarm until we had kids. Now I can't sleep in enough (nor am I allowed to ;).

I find it hard to believe you _only_ use Septa to get around Philadelphia. I have the regional rail pass for my commute as well and Philadelphia's public transportation system is not great for getting anywhere in the city. I uber all the time to get around Philadelphia to supplement my Septa pass. It still definitely beats a car payment, insurance and the hellhole of parking though.

At least compared to NYC, where I could hop on the subway to anywhere in the boroughs.
Thoroughly Modern Mongo: Modernising the MongoDB Codebase
Free transit is mostly an edge case. It's almost always limited to small cities or municipal areas (including in Europe), and often target the elderly and students. There are interesting consequences to free public transit, such as picking up some new kinds of riders at the same time as turning off other riders. But it can be pretty effective in the right cases.

Baltimore has a free shuttle bus called the Charm City Circulator. It's not intended to move people around the city. Instead it's targeted at a central problem area that may otherwise be prone to increased traffic congestion, pollution, and slower or lower ridership. It also facilitates tourism and gives an incentive for workers to live in/near the downtown area.

The CCC is popular enough that it's hard to get on one heading downtown in the mornings because they're so packed with people heading to work. And strangely enough, it's much cleaner and with fewer undesirable riders than regular (paid) buses in the city. This is probably due to the historically segregated layout of the city and the particular routes these buses take. The biggest problem with the CCC is it hasn't been funded or maintained properly, so these strange custom shuttles are breaking down and there's nothing to replace them. As a result they had to cut down some of the routes, while they also expanded the most popular route to travel farther north.
Using Metadata to Find Paul Revere
Well... I don't particularly agree with everything this guy is saying, but he is right about the internet of things. In my experience, it is quite useless, and it is a danger to privacy. One of the my friends constantly uses Amazon Alexa and Siri for even the most basic questions like, "What is x + y?" which could be easily done faster on a desk calculator. Either I am a person who likes to make things more inconvenient for myself, or I just don't understand modern technology.
How did you resolve it? Did anything happen to the employee?
I use a 6 year old phone. It has a third party extra thick battery and a microSD card slot. It does the core functions of a phone just as well as a modern one (voice call, SMS, clock, calculator, flashlight, music player). The camera is worse, but if I cared about quality I'd use a standalone camera. As for apps/Internet, it's roughly the same as modern phones: a whole lot of barely usable garbage only suitable for emergency use when you don't have access to a desktop. It seems to me that any modern phone would be a downgrade.

I work on some Mac applications that, at times, try to exceed what MacOS applications are capable of doing.

They almost always break between MacOS releases. Usually the cause is that Apple improved various security restrictions in Gatekeeper. What tends to happen is that older builds work fine, but any new builds don't work well.

But, what's interesting is that the page at https://worthdoingbadly.com/assets/blog/appkitcompat/appkit_... doesn't list any bundle hashes. I always assumed that Apple's hacks for backwards compatibility were tied to the bundle hash, and not the specific application.
I don't disagree that the topic is important, I just think we have much better critiques being written on that topic regularly, from both inside and outside the tech industry.

Also, the SV reality distortion field hasn't infected all the tech industry. In the companies I worked, nobody was convinced we were changing the world, we're just writing some tools for cash.
Land prices determine the larger share of a house price. That depends on what other purposes than housing, the land can be put to. Also infrastructure cost, taxes and transportation.

And nobody is going to build a new house if they can't make good money on it. So its all tied up in interest rates, expected rate of return for capital etc.

Supply can matter say in a depressed area where folks are in a hurry to get out from under a mortgage. But nobody is making money there. Its not a typical house price at all.
Yep, I've sheared some tools trying to get them off. Being able to rent a car with air tools would be nice for DIY stuff. It would probably be too expensive insurance wise though.

Seven things I’ve learned building a browser app in WebGL
Awesome, thanks! I'll try these.
Let's remember this, from the last few years, written by numerous major media editorial pages (paraphrasing, of course): "Silicon Valley never tackles the big issues. They just invent frivolous new gadgets which no on really needs, or some new app that shares pictures of cute kittens or is the next social network. They should focus on big picture issues - hunger, housing, crime, etc."

Those are harder to approach and solve, and you need more patience for results. Now we see complaining that the nifty gadgets aren't coming like they used to. Hmm.
The only thing worse than a useless blockchain project is a useless article that doesn't provide any value but just parrot what other people say, in the most distracting an attention seeking way possible.

If you want to make a point about why blockchain is unnecessary, write an intelligent article about it. This "article" provides 0 value and it's so obvious that they just want to get traffic.
I used to maintain a Finder plugin that added icon overlays to files, and added menu items to right-click menus.

It worked by injecting code into Finder at runtime, and then swapping method implementations for various classes. (Mac developers call this swizzling.)

We basically had to reverse engineer Finder every time Apple shipped a new version of MacOS. Later, as the process grew more common, we had to add tricks to make sure that we could work smoothly with other similar plugins.

I jumped for joy when Apple released the Finder Extension API!

I don't think it's just nostalgia and survivorship bias. The median quality of content on the Internet has become objectively much worse, mostly due to a race to the bottom and a race to make the most "viral" thing to cash in quick. Media has always been a bit of a deflationary race to the bottom but this is quite extreme.

Top 5 Project Management Trends in 2018
> Firstly, It doesnt have to be illegal.

Yes, in the US, for government to break up a company, there must be something illegal done.

> This doesnt happen in any other industry, not with any other company and definitely not in any industry as lucrative as search ads.

Clearly, you are posting from an alternative universe where Microsoft, who has held overwhelmingly long-term dominance in at least two different markets significanlty longer than Google has existed (desktop OS and enterprise productivity suite.)

> Thirdly, Search is critical infrastructure.

If true, that would be a reason for it to be a public utility, not to break a Google. But if we can't even get a consensus that actual internet access should be a public utility, good luck making the case that search is.

> How do we know that publishers do not self-censor content critical to Google lest they get bumped from search.

In systems with due process, punishments aren't based on “how do we know X is not true”, but instead in “here is the evidence by which we know X is true”.

Take small microphone element that captures human speaking range vibrators and connect it to equally small retroreflector. Then you can read the sound from any angle using laser/sensor next to each other. There would be no electrical or radio frequency transmissions at all.
Hunger, crime, these are not technological issues solvable by tech companies, unless your idea of a solution involves building a more effective police state. These are political issues our leadership has neither the will nor incentive to solve.

Yes, deliberate practice is my favourite topic.

I find ego to be persistent, expansive and not very deliberate. Mythical or fictional identities are deliberate, perhaps through their ephemeral nature, limitless yet constrained. For me it's a way of tapping into a play/flow state and compartmentalising away stress and uncertainty. As a teenager the mythic entity was my self; as an adult I have had to turn elsewhere to find that spark (this was a very painful lesson).

Part of Flagler's motivation for building the railroad was beach property rights. The government at the time incentived railroad construction by granting land along the sides of the rails extending several miles.

By building the railroad Flagler gained rights to most of Florida's east coast beach property. So in a sense, Miami was a giant public works project.

Are we going to be willing to do the same for space exploration?

Swap out the stock distribution - I'm assuming Android here - for something like AOSP, leave off the Google-specific bits (i.e. do not install 'gapps' or anything which depends on it, install the mock-google-bits instead if you want to run something which depends on Google play services. Use F-Droid instead of the Google play store. Voila, a phone which does not do silly updates behind your back, does not install apps you do not want and which should last for years and years - mine is about 7.5 years old now.
Some survival bias maybe, but I agree, content was better, and I believe mostly because there was more work put into the content. Today a lot of work goes into presentation, into using words in common enough dictionary ( see https://blog.xkcd.com/2015/09/22/a-thing-explainer-word-chec... )

But don't forget that there was less content, and soon the era of blogs rose, for which I read a fascinating description lately:
