I think the article assumes that "from scratch" means that you have to make those, too (including the kiln), and including all the tools you need to mine the graphite.
"The technology also promises to be more secure than ordinary Wi-Fi as the light is unable to travel through walls, meaning that connections are more secure and there is less interference between devices."

I don't understand how there could be "less interference" between devices.. Ok I get the transfer range, but how about particles in the air, birds, etc? Wouldn't packet loss be an issue here if something interrupts the stream? Unless you had multiple transmitters repeating the data...

5 Reasons Not to Choose JIRA for Your Agile Project
Example of the problem with mass transit : http://www.uwgb.edu/dutchs/pseudosc/masstransit.htm

1) Money: generally speaking, depending on the number of passengers mass transit is a little cheaper (1 person), about the same (2 pers) or much more expensive (a family of 4-5) than public transport.

If you take into account that home -> work -> shopping -> home with public transport turns into home -> city center -> other city center -> work -> city center -> shopping -> city center -> other city center -> home ... The point is that there are many kinds of trips where the routes taken by public transport cause it to be more expensive than a car.

In the cities where I've worked, mass transit (2x bus + train) was only 20-30% cheaper than a car and only if you lived out in the suburbs and worked in the city. The other way around (living in city, working a bit out of the city), mass transit was more expensive than the car. Living in city, working in city, a fold-up bike was far more convenient.

2) Time: mass transit doesn't go where I live, and doesn't leave/arrive when I need to leave/arrive. Furthermore, it's regularly non-operative when I need it. This limits what I can do (I stayed late, we ordered in pizza, then hang out with a friend ... oops it's 22h30 ... no more buses to my place until 6 am. Yes it only happened to me maybe 5 times over a decade but fuck that shit)

3) Baggage limits: when using mass transit I can carry 25 kilograms. If I don't care about comfort of myself and other passengers, maybe 40-50 is possible. I don't imagine I will be able to do that anymore when I turn 60. If I have my kids with me, 20 kg is pushing it, and if I'm either slightly ill or ... I can barely take anything at all.

When I go shopping, I buy for the week at least (by far the least bothersome way to do shopping imho, a lot faster, and also 30% or so cheaper) I come home with 30-40 kilograms usually. Can't use public transport for that.

This is ignoring that a lot of things can't be reasonably/safely transported using public transport, like DIY building supplies (ladder, long bars, 2 by 4s, ...). This includes anything heavy or above a certain very restrictive size limit.

4) Comfort. I don't even get why they bother with 1st class on trains. Let's not pretend that even 1st class has 1/10th the comfort of a car. Commuter trains are torture.

Mass transit is usable as a commute solution. It cannot reasonably replace a car. We need to fix transport and mass transport as it currently exists is not the answer.
Let me explain then.

In a scenario where you use land to grow food, if you don't own the land you can't say you control it. How this that the case? You can state you control it without owning it, and use that land to grow food. However, that control only lasts if only one person has access to the land. If I decide to dig up all of your crops and use the land for my own use, then do you really have control of the land? No. Neither would I in this scenario, anyone could undo the changes I made as well.

Ownership enables exclusive control. When it comes to managing resources, there is no reliable control without exclusive control.

In other words, in this case, there's no point in making the distinction between ownership and control.

"Instead of tolls"? Why not both? Tolls should pay for mass transit. It's a win win. Want to take your car? Good, you are then paying tolls that subsidizes someone else taking the bus. I thought almost all cities that have congestion fees use them to pay for more public transit?

If only we had self-driving cars. Everyone talks about them as if they are a done thing, but they're still under development and it seems there are still huge problems to overcome. That includes technical and legislative issues. Even if those problems can be overcome, will people actually want to buy them? Will they be able to afford them, or will these effectively be luxury/status-symbol vehicles? I think it's too easy to succumb to Nirvana Fallacy when we discuss them.

Superior only for a specific group of people. People who want a tiny chunk of binary info. A niche market, but one that exists.

You are claiming a universal inferiority. Deriving a universal principle from your own singular experience.

That inability to recognise the existence of other viewpoints, and other markets, is why you need a designer's empathy.
My guess.. we're talking years of investment in a (presumably monolithic) "huge" Delphi system.

Living and travelling in big European cities (London,Paris,Vienna,Munich,Prague,Dusseldorf,Dresden,Linz,Bratislava), I strongly disagree. Commute times are mostly in favor of public transport (especially where separated from individual traffic, e.g. the underground), even with transfers: cars are gridlocked, trains move (and in most cases, they move on time).

Oh, but there's all those pesky people in public transit - well, that's what distinguishes a city from living out in the woods, no?

I wrote a fairly popular Python library to easily generate short UUIDs (encoded with base57):

https://github.com/stochastic-technologies/shortuuid

Since it turned out that most uses didn't actually need a UUID and just needed a random string, I figured I'd maximize the randomness per bit and added a .random() call that returns a short string that is taken from os.urandom().

It would probably be good if you asked yourself whether you actually need a UUID or a random string, and used the right tool for the job. Using a UUID when you want a random string and vice versa leads to these kinds of problems.
Sorry, i just happened to hear the exact same story at an event recently. :)
To be honest they should teach JavaScript instead of Python in highschools. Websites ('web apps'..) are a big deal in, atleast, teenager's life, so they could atleast install Tampermonkey plugin and script some functionality for their favorite websites.

Meanwhile after learning python if you won't work in IT is useless. Plus requirement to install Python, include python in PATH and use CMD to launch .py scripts is a detterant, while with Javascript you just press F12 in browser and bam - development environment ready and lets you to manipulate open web page, which is also more exciting than console applications.

Ottawa researcher to students: Don't be scientists due to 'dismal outlook'
The 80s are widely considered as the golden age of hacking, but what the hell? I just bought ten microcontrollers that can run Lua/Python/C for $20, there are full-blown computers for $5, and all the supporting ecosystem (sensors, components, etc) is cheaper than most toys.

I am very optimistic about the future, given that people (and children) these days have trivially cheap access to powerful programmable and easily connectable computers, and hopefully they'll start to demand more and more that all their other devices are equally hackable. If most people have a microcontroller at home that they made themselves that controls the coffee maker, they will want to be able to connect other stuff around the house up, and that can only be done with open protocols.

The next few years are going to be very interesting on the maker scene.
I am doing something similar to this. My setup includes multiple temperature sensors in addition to a Raspberry Pi thermostat which controls my heating system. The thermostat also acts as a HomeKit server, and so can be controlled using Siri - which is really just a fun party trick more than anything else.

(I know Nest and Ecobee can probably do all of this out of box -- my reasons for building this were just to tinker and learn)

Here's what I use:

Sensors:

Since these are likely to run on batteries, you'll need to choose a platform with allows for low enough power consumption that you aren't draining the batteries too quickly. This is suitable for the microcontroller-based options (Arduino, ESP8266, NodeMCU, Particle), but not for R-Pi (due to too-high power consumption). In addition to the platform, your code will also need to take advantage of power saving opportunities, like going to sleep and disabling battery-draining radio services like WiFi, waking up periodically to take a measurement, enable WiFi and emit the metric before going back to sleep.

For my temperature sensors, I chose to the $19 Particle Photon [1] for the following features:

- Built-in WiFi
- Built-in REST API (goes through Particle's cloud REST API)
- Add a temperature sensor like TMP36 [2] to it and your sensor hardware is done.

Thermostat:

For this I use a Raspberry Pi (plugged into wall power) + a relay breakout board to interface with my heating system. My thermostat needs to periodically do things like access google calendar, keep a log of temperature data, to run a HomeKit server [3] [4], and to be ever-ready to respond to REST requests from the internet (eg. IFTTT). So, it's more like a real server, for which RPi was much more appropriate.

Data Storage:

Many options here. Take a look at Phant [5] from SparkFun form something quick and simple.

Aha, perhaps that is the issue: if Portland, billed as mass-transit friendly, sucks this much w/r/t MT, it's understandable that people would try it and say "well if this is the best mass transit can do, then no thanks."

Edit: Went to check the map - and yes, it does look very...rudimentary. http://trimet.org/maps/img/trimetsystem.png
There's a whiff of the 'no true Scotsman' fallacy about this though. The OP was suggesting that some designers are focusing on the decorative aspects of design because that's what looks good on a Dribbble profile. Given that 'making pretty designs' is a learnable skill and that at least some companies will hire people based on that skill, you're going to find a non-negligible number of people employed as designers whose primary skill is in making things that look good, rather than things that work well.

The other problem is that even if a designer is conceiving the product holistically, if that design is communicated in the form of PNGs or PDFs, it's unlikely that their vision is going to be understood correctly. In a collaborative environment, everyone needs to be part of the design process, because many aspects of good design require an understanding of the thought process that leads to the product as an outcome. The idea of the designer as a visionary who conceives the product and then hands off designs for other people to build is a seductive one, but it very rarely works.

I've been wondering what is the analogue of syntax highlighting for natural languages. Still experimenting with it, but most promising is simple keyword highlighting. I've written a Chrome extension that does this:

https://chrome.google.com/webstore/detail/highlit/cooahmcpma...

Interestingly, keyword highlighting apparently helps some type of dyslexic people focus their attention on the text. With the web full of distractions, I've noticed similar effect myself. Keywords also seem to help skimming, when you're reading the text with a specific purpose in mind.
Good point. A few weeks ago I made a similar point here on HN, that web dev is good for starting.

Given more thoughts, I am fairly conflicted/confused about web apps vs Python :)

Web apps, as you've said, are pretty straightforward, minimal setup, extremely easy to relate to. I guess many folks who aren't familiar with coding have an idea for web site or two. That makes it a great motivator, no doubt. If a friend asked where to start, I'd probably point to this direction. HTML5 games is a pretty good choice too, and Phaser is a neat framework to start with.

However, there are a few problems with this approach.

First, most of the development/studying would be more about the details of browsers/jQuery/javascript itself. How to get the content of this input, how to attach this event, etc. The problem is that it doesn't do much to teach the mindset of programming. You know, when to apply for loop, when while loop, etc.

The other problem is that web dev is moving much much faster than most of the education systems in the world. In 2010, you probably would have taught about jQuery. In 2015, you probably would use vanilla JS as it's good enough, modern browsers are following the standards well enough. And then you have all the html5 elements (video, etc), css3 properties which are fairly important nowadays but didn't exist 5 years ago (or the browser support was poor).

So, web dev might work quite well for motivated individuals and equally motivated teachers but probably less so for mainstream education (i.e. highschools).

Turing reneges on drug price cut, rival’s version sells well
As an animé fan I was surprised how low the "Manabi Line" is. Less than 3000 sales is about break-even, and that's for a production that was the work of many people (the Japanese model is (generalizing broadly) to sell more expensive products to dedicated fans; CDs can be around $30 (but are often "deluxe" versions with lots of special features) and in the case of animé a single DVD can be $60 and a series will be spread across 4 or more volumes).

So I think there is a sustainable business model where, rather than trying to go mass-market, you sell a specialized product to a much smaller number of very dedicated fans.
You can't actually get the USD$5/AUD$7 version from piaustralia/littlebird though. It's a kit for AUD$25 (plus AUD$7 shipping) and no other option.

I ordered one from PiHut in the UK because that was the cheapest I could find (AUD$16 including shipping).
No, I think in many projects designers are decorators - which leaves no one in charge of the user experience from the point of view of the user.

In the same way that a full-stack Linux expert isn't going to understand how someone without 5+ years of command line experience approaches a computer, a trained designer with an experienced eye is always going to struggle to point themselves in the place of a naive user.

Good UI needs to be tested for design assumptions and for user taskflow. The testing needs to be repeated every time changes are made. For any business with a web site that sells to customers, this is at least as important as unit tests in code.

IME designers aren't often interested in this. Some are, but many simply don't get it. And even if they are, there's pressure to see UX as a machine for driving conversions (hence the same Bootstrap template with the same social proof and the same calls to action everywhere), and not so much as a way to make the customer experience more positive.

The proof is that many sites are broken in some fundamental way. I was on a logistics site yesterday trying to organise a redelivery, and the site simply didn't do what I needed. The graphics were pretty, but it obviously hadn't been tested properly, and many elements were broken.

Yesterday's example was unusually bad, but similar issues aren't unusual.

Being a professional coder who is now studying design one thing I've discovered is that most people underestimate the scope of good design and seem to want to narrow the designer just down the prett visuals, discounting anything unseen (eg process).

Another difficulty is that much good design is obvious in hindsight, think iPad but the act of whittling away what is unimportant is a key part of the job.

Or yeah maybe you've just dealt with poor designers.
