Data on radio channels is common! All you need is a "radio" and a "modem," and there are many variants of either.

These kinds of radio channels are already allocated to 'business' or 'government' service by the FCC. The user has licensed the use of one or more in a specific geographical area. These channels are 2.5kHz wide, but the old fashion was 5kHz bandwidth. They were allocated with FM audio in mind, which is what the portable radios do. You're normally allowed to run data on these channels.

The radio used at each node is probably a "mobile" radio intended for mounting in a vehicle but configured as a kind of base station by adding a DC power supply. Motorola has been selling microprocessor controlled, frequency-synthesized radios since the early 1980's, and the earliest one I know of used a 6800 processor (actually Hitachi 6300 series clone of M's cpu). The channel is probably shared with the maintenance chatters because the county already had the license, a radio fleet, and a shop to maintain the radios. By changing a "CTCSS" or "PL" tone to one that is different to the ones used by the voice radios, the maintenance chatters don't have to hear squawks and whistles all day and night.

The modem is probably an FSK kind of modem with a rate of something like 1200 bps. This works by representing 0 and 1 with different audio tones and is very simple with complete integrated silicon available during the 1980's. It's interfaced to the radio's audio input and output, the computer/modem needs a way to cause the radio to transmit, and it is nice to have a signal to show whether the radio channel is busy or idle. Otherwise it is probably a serial interface to the local controller at each site. The modem itself may have a microprocessor to do simple tasks like ensure the transmitter does not get stuck on by a fault or to prevent transmitting when the radio is receiving a signal already.

As far as the protocol goes, it can be anything and is probably something extremely simple: My address, length, payload, checksum.
cURL can handle gopher. I was actually surprised Firefox couldn't. I guess they removed it at a some point.
I used two 24"-27" monitors for several years to do web development, but then I stopped. There was a definitely advantage to having an entire web page visible while I was working on CSS. It was also great to compare full code windows side-by-side (like when refactoring).

The problem for me was neck and shoulder strain. Constantly turning to the left or right always gave me problems. My posture degraded as I naturally moved farther back from the keyboard to take things in.

I dropped the second monitor a few years ago. My physical problems have gone away. I enjoy looking straight ahead now, and as others have mentioned, using a laptop on the train to code no longer feels limiting.
> I'd hope that serious investors know the difference between accrual and cash accounting.

This comment surprises me a little. Have you ever met a serious investor that doesn't know the difference?
I don't know the details on this particular case, but its not on the face of it ridiculous.

Currently, European oil and gas corporations are pushing for a carbon tax. The reason is that they think they'd displace a lot of coal usage if both where priced accurately. In the US the coal lobby is currently stronger than the gas lobby (even with cracking).

Corporations compete, even in lobbying, sometimes this leads to surprisingly positive sounding outcome.

(I say "sounding" as its not clear if the worse-than-carbon-for-climate-change methane that gas production produces would be costed properly if gas companies are driving the "carbon" tax)
I don't understand why Google can not roll this out internationally from the start. Why only US and UK?

The content is not subject to old copyright contracts, which is typically the argument not to launch something in Europe and its crazy copyright situation. And twitch is available everywhere.

If Google wants this to become a success, shouldn't they roll this out to as many people as possible and hope for network effects?
That seems illogical to me. I spend 90% of my time at my desk with a 2-monitor setup. When I have to use a laptop I do, but it would be counter-productive to use it all the time.
IBM Model M, mouse, loads of screen vs poor keyboard, trackpad, tiny screen. I don't get it.
why does your teacher need a license? background check, sure, but license?
True. A few years ago we still needed to build our own laser cutter[1]. Few places provided laser time and turn-key systems were super expensive. We eventually published the design and more than 200 hacker spaces and universities had the same problem and built the system as well. These days lots of people can find a hacker space with good tools very close to them.

I just started a new job in meteorological model development and even though the company is now quite large, everyone in my team is running Ubuntu with only one 24" monitor. At first I felt it was cramped but now I feel that it allows me to finish off small micro tasks first before I interchange between windows. Using two monitors, I'd often leave things/code unfinished because I'd shift all my attention to another screen.

Money isn't really an object at any kind of serious tournament - everyone has/ can borrow all the cards they need to play.
In my country certain electronics engineering jobs require a license. The licensing system and the exams are a joke, they don't test for engineering ability at all, more like trivia and formula-memorization tests.

Fortunately, only a small subset of jobs (radio and TV operations) require it, and the best graduates don't want to work those jobs anyway. Most engineering companies ignore it if it isn't legally required for the position. They instead look at where the applicant got their degree and relevant experience.

A large part of the problem I think is that screening thousands of engineering grads properly for engineering competence would be prohibitively expensive and time-consuming for the government, and no one wants to admit the system is broken.

I suspect any government initiative to regulate software development is going to run into similar problems. I wonder how the medical and legal industries do it.
People aren't going to stop watching their favorite personalities just because they switch to YouTube. The only thing YouTube has to do is convince some big names that they can make more money on their site. And that should be easy to do, if it is in fact true. A couple of small streamers are surely going to try it, and if they report good results, more and more people will switch.

You have to make a distinction between someone who's writing a research paper, and therefore constantly checking sources, and someone who's writing fiction. For the latter, a single monitor is less distracting, but for the former, a second monitor for the sources can be beneficial.

I'm not sure it is dumb if a company spokesman says something in favor of his companies current situation.

Steve Jobs famously said the kindle would flop because "people don't read anymore"
Interestingly they've built two different versions of the typeface: Compact (for watchOS) and UI (for OS X/iOS). Compact is far closer to DIN or Roboto (with flattened vertical strokes on glyphs like the uppercase C, D and G), whereas UI is far more rounded, and looks a lot like Helvetica for some glyphs.

I was concerned based on what I'd seen of the typography of the Apple Watch that it'd be too cold and characterless (I really dislike Roboto on Android) to use across OS X and iOS, but by creating this separate UI variant they're able to make it feel like a gradual transition from Helvetica Neue. It's so similar, in fact, that I'd not be surprised if we end up seeing more font quizzes asking: ‘Arial or Helvetica …or San Francisco?’

If you'd like to see the fantasy paradise that would exist if we abolished these foolish regulations, come to England some time. Then hire the first guy in the phone book who calls himself a "plumber".

You would not believe the number of unnecessary holes in my house directly caused by a single plumber's mate (defined: guy willing to work for £8/hr) attempting to do his profession before we could physically remove him from the property.

Same goes for "builder", and to an extent even "electrician." It's amazing to watch, coming from America where people are required to be qualified for their jobs.
The main reason the MTGO economy is broken is simple: MTGO is incredibly shoddily designed and coded. It crashes all the time and has so many memory leaks they still plague users ten years after it was built.

All of the issues lead to a LOT of refunds, essentially doubling the product (tickets and cards) in circulation.

Recently, the game moved over to "4.0" which was even worse than 3.0 which has, in part, exacerbated the problem.

This actually has a knock on effect on the paper magic markets where card redemption (can turn digital cards into paper cards) has a big impact on prices. There are countless articles on MTGPrice.com about this.
Fashion and taste evolves, and not always for reasons that are easy to articulate, especially to the laity.
I disagree. Maybe because I don't exclusively do web development, but I find I'm significantly more productive with on monitor than two.

I switched from a 15" thinkpad to a 13" mackbook pro about a year ago, and even just that screen size and small resolution switch makes me feel more productive. They're comparatively speced, the only real difference is size and bulk, and that the macbook has significantly worse graphics capabilities, but in the grand scheme of things, they're basically the same underlying specs for development, just with a different screen.

Yeah, it is a bit of a pain to have to switch workspaces, or just rotate through windows to recompile something, or check a modification made to a web page compared to just turning your head a little, but because I'm forced to pay attention to one main thing at a time, I feel significantly more productive at that one thing.

It's mostly like the author said, removing additional distractions from the screen.
Using keyboard shortcuts to quickly switch work spaces seems to be the best of both worlds. It allows you to keep distractions out of sight while requiring minimal effort to quickly access other screens/windows when needed.
The flash survival rate heavily depends on how the system is configured. If you move every writable directory (/tmp, /var/log, /var/run, etc) to a tmpfs filesystem and make the main filesystem readonly, it'll live much longer (and better survive hard reboots).

It seems to resonate. One of the most mature guys I ever met had been forced in his late teen to take over running his father's construction subcontracting business, help his mother get around (they immigrated to the USA and the mother didn't speak English well), help his younger siblings graduate high school and get into college, and help make decisions about his father's cancer treatment for a year before his dad passed away.

I met him when he was about to turn 30, and after we'd known each other for a while he told me about it. He was one of the most calm and steadfast people I ever met; nothing ever got to him. And when you think about it, that's exactly the sort of maturity you'd expect that someone who was head of household for 15 years, helped raise 2-3 kids, ran a business with some tough guys working for him.

He explained it all rather matter of factly, made me reflect a lot on what maturity is. Given a really horrible set of cards, he managed to take care of everyone as best as he could and got his family through it. And things that would set almost anyone off didn't even register with him.
Individual private tutors (in the UK at least) need a background check if they teach children under 18, but not a license. Teachers of whole classrooms in schools need a QTS, which is a qualification demonstrating their skills as teachers. This seems reasonable since it gives a fairly simple way for parents and schools to evaluate whether a teacher is completely useless or not (but not that they are a great teacher - a license probably could never tell you that).

I'm interested to know why you (I assume) think licensing teachers is a bad idea.

What you're describing sounds a bit like the left-libertarian philosophy of Agorism (https://en.wikipedia.org/wiki/Agorism), and counter-economics (https://en.wikipedia.org/wiki/Counter-economics).
You can have delays for that purpose in real-time systems too. And they'd actually be consistent, instead of having variable lengths to cancel the transaction.

and almost no one ever was. Independence from family is a very modern American notion. For most of history and the world, family/clan interdependence was/is a major component of culture. Modern left-leaning societies installed government-run interdependence to replace the clan (and some rare far-left governments displaced the family)
It matters for anyone who maintains your code. "!=" is a big red flag, better to consistently use "!==".
Don't get me started on tradespeople in England. My mum calls out random people to do jobs once in a while (plastering, carpentry/joinery, decoration, general DIY) and with the exception of one plumber, they have been low skilled, lazy and they did not care for doing a proper job.

The worst thing is that even these idiots are in demand and struggle to return calls.
Yes and please do blog about it regularly if you feel like it - this whole thread on legacy systems is the most interesting read on HN for a long time IMHO.
Good question. The stated goal (generalizing of course) of the LVT is to replace most other forms of taxation, particularly income tax. I've seen napkin calculations where that's possible, but the other side of the question of course is the payout. Most 'realistic' estimates I've personally seen of that don't necessarily assume that a UBI will provide above a very basic living. There's usually the intention of incentivizing additional income, but the UBI at least provides the security to be selective in the job market or promote risk taking in ventures. By the way, it's also apparently commonly held among economists that the LVT is a very efficient tax with low evasion. The difficulty in implementation has historically been considered to be land valuation itself, but recent advances in things like GIS apparently make high resolution valuation feasible.

>I wonder how the medical and legal industries do it.

Do they actually do it with any success? According to this article: http://www.forbes.com/sites/leahbinder/2013/09/23/stunning-n..., medical errors represent the third leading cause of death in the United States. Medical licensing makes it hard to enter the industry, but it doesn't seem to do much good of forcing dangerously incompetent practitioners out of the industry.
Is Deutsche Bank the Next Lehman?
Indeed. If this were the old Apple the devs would have snuck in an easter egg which changes the watch face to a mouse-like cartoon character that totally isn't a copyright violation, honest.
Calling yourself a developer is pretty humble, today we have self taught people like me calling themselves engineers and architects. Unlike an actual engineer or architect who will face some kinds of consequences for failure, our current system is too easy on those who build and ship defects.

The closest I saw in my professional career to fixing this problem was at a shop which implemented ISO9000/TL9000 processes in such a way that anyone who signed off to approve a defect would have his career ruined. It seemed to work well for us.

Now that computers and electronics are directing and controlling processes and operations that have a potential to cause damage to life, property and economics, I think that at least certain areas of these "engineering" fields should require proof of competency before practice. We are drowning in stories about all kinds of defects from information leaks to process failures, and very few of the responsible parties have faced any consequences at all.
> 86 percent agree with the statement, “I am confident that eventually I will get what I want out of life.”

Could it be because they don't actually want much, or anything?

Wanting insn't that easy. You have to be inthe kind of place that let's you see what's possible without letting you get it. Too far, and you don't know what's out there. Too close, and you already have so much that no object of desire is left for you to «want».
This depends upon how you use the second screen! If you keep your email client open at all times and in view then of course it will distract you. However, if you keep several source files open at the same time then you can quickly switch between them.
I'm pretty sure that if you move just a little the image, the convnet is no longer fooled. So this kind of exploit works only for completely stationary images, and it is very to overcome.

This is exactly what I've done - the Philips BDM4065UC is a 40" 4k monitor, so the overall pixel density is about the same as a 24" 1080p. It's like having 4 x 1080p monitors in a block. Also it runs at 60hz over a single displayport cable if your output supports it.
I don't think Plato's critique there is necessarily getting at what you're intending. Plato is arguing that direct commands by a ruler are superior to written statute laws, because they allow for the use of good judgment and have less scope for bureaucratic idiocy and corruption than a lengthy statute book does. He's not against the state imposing restrictions on anyone, he just thinks it should be done by direct command of wise philosopher-kings, rather than by codified law.

His system if anything quite strongly restricted what people could do in the economic sphere. The "producers" were one of the three classes kept strictly separate (the other two being warriors and rulers), and must follow the directions of the rulers, as enforced by the warriors, in order to ensure that production is in keeping with the needs and morals of the polis.
Traveling in Europe on a limited and expensive 3G connection, I'm acutely aware I'm paying more for the bandwidth these ads consume than the advertiser is paying to display them. The ads consume 20x more bandwidth than the content.

I'm subsidizing the ads! You say ads are moral, I say as implemented, that's immoral.

I didn't say it was easy. redis is full of reinventing the wheel in the name of improved performance. This is something developers often do, but are often told it's pointless, just use built-ins.

Salvatore has found a niche where he can see these optimized implementations to their end. I would imagine there is a certain level of satisfaction that comes from thoroughly researching a topic, implementing it as best you can, and deploying it to the public you're popular with. It probably helps having firm control of the project with less red tape.

It's like a comparison between a craft woodworker and someone who would like to play around with the concepts, but doesn't have the tools, time or know how, or they're told there is no point in building your own furniture from scratch, so they are instead building Ikea furniture.

If you want to get used to working with one screen, that's perfectly sensible, but there's no need to force yourself to use only one screen all the time. You can simply get used to both environments - and I say this as someone who works with two 20" monitors and is now typing on his personal 12" laptop on a coffee shop.
