Suppose you're going on a 100 mile trip and you want to know how much better off you are if you replace your 50 mpg car with a 100 mpg car. You now only need 1 gallon of gas instead of 2. Even if the car can run without gas, you aren't any better off than a savings of 2 gallons for the trip. You're not > million times better off.

To some extent it's fallen off because we've reached (somewhat) of a plateau. Originally all mining was done using CPU resources, but the first big jump up in hashrate came as folks started to figure out GPU mining. As GPU mining grew more popular, the hard core geeks started looking at FPGAs and eventually we made it to full blown ASIC miners. The last big explosion of hashrate was driven by the bulk of miners adopting ASIC hardware of one flavor or another. Now that the majority of miners are on SHA256 ASICs the only gains to be made are by shrinking the die and increasing the transistor count but even those hard earned gains are going to be quickly diminished as ASIC hardware "catches up" to Moore's law.

As for hash power leaving the network, if you are mining as a business then you are 100% at the mercy of 1) how much you pay for electricity and 2) market price for coins. Given how many schemes exist for stealing either computing power or electricity I imagine the margins will converge on a negative number at a large enough scale.
> I guess it depends on how you define uninhabited - if I've got a 50,000 acre ranch with a 2800 sq ft house on it, most people are going to call the bulk of that land uninhabited.

Okay, but then then suburbs are uninhabited too. The neighborhood I'm in has 1500-2000 sqft houses on 10ksqft lots. That's 80-85% uninhabited, especially once you start to add up the amount of extra land for streets, ditches, canals, parks, etc. I bet most suburban landscapes are 90% uninhabited.
> Zipcar can track the cars using GPS but they told me they can’t turn off the engine remotely.

A less extreme (and litigious) option could be to just turn on the car's alarm remotely. It would make the prospect of stealing one far less attractive to thieves if it was known that the alarm would start blaring at some random point after they've driven off with it.
The same way you would calculate the password and if you knew the site salt and the per-user salt.

Or the password in case there's just a user_pw+salt :)

In that case it's simply that the "site salt" is the "password" you after it, since you know the 2 other variables you just randomly generate the 3rd one, hash it and see if it matches.

Just like most developments in the bitcoin world, I'm having a lot of trouble figuring out what this thing actually does and why I want it. Isn't the whole major selling point of Bitcoin that it isn't physical and is instead totally digital? What does a "bitcoin command line" even mean?

"With this pocket-sized device, if you are an entrepreneur or developer, you can now instantly buy or sell digital goods and services at the command line using Bitcoin." Isn't that already all possible with just bitcoin itself? Why would I buy this thing?
What science needs, I believe, is not another tool for making TeX more usable for information interchange, but a simple (much simpler than LaTeX, whose complexity and user experience is terrible), web-oriented standard language for typing in libre scientific and technical documents that browsers would support (or it can be translated to valid HTML+CSS seamlessly). Web documents are cheaper and more accessible to people, we should concentrate on those. I don't know if there is usable language and platform of this kind already. When we'll have that, tools for converting web documents to other less important formats such as paper-printable ones can be created.

This is because this is entirely intended for software defined radio and modular radio - around which the entire point is the RF component does not contain as much signal processing logic, and that is done in software. Restricting software defined radios to specific frequencies in hardware would take away the entire point of modular/software defined radio.
For a long time I thought the Apple va Android rivalry was invented by the two companies so that all the press would be about them, rather than Microsoft being given the default position as the incumbent.

I think I was overestimating them, but once again think that's a feasible strategy, Tesla vs Apple fanbois arguing on the internet could be the best thing to ever happen to all-electric vehicles, and leave petrol and hybrid cars looking archaic, rather than the current paradigm where its Tesla vs the old industry.
In most places, you don't hail a cab on the streetcorner by raising your hand. In most US cities, you call dispatch.
This was surprising to me! I always figured my Zipcar wasn't much of a target for thieves because: It has a big Zipcar logo emblazoned on it (slows down turnaround of the car if you're trying to sell it), it has the custom Zipcard locking mechanism, which is tied into the car's alarm system, and each car has GPS in it, which you'd think would lead the cops right to them.

Wondering what use these cars are to thieves? Is it just a quick way to grab a ride somewhere (maybe out of town)? Are they actually selling these cars intact to people to be repainted/refitted and sold? Or are they sold for scrap/parts?

> The 21 Bitcoin Chip means your 21 Bitcoin Computer has access to a constantly replenished source of bitcoin.

> This means you can now write programs that connect to the Bitcoin network just as easily as they connect to the Internet.

It sounds like the mining is intended to create a constant supply of bitcoins so you don't have to "top up" your wallet. Then the bitcoins are used to process things (putting information in the blockchain) and you're also selling access to run sandboxed code on your machine - presumably code which interacts with the blockchain.

They've phrased this terribly by saying you're selling "digital goods and services", overly broad and meaningless words.
First off, the sales happened between 2003 and 2011, so nothing has happened in at least 4 years. Plus, the 9500 rifles sold are a drop in the bucket compared to the Colt and Century Arms weapons in common use.[1]

Second, the weapons in question were sold to local Mexican governments.[2] The investigation appears to stem from the German government not trusting all elements of the Mexican government to use the weapons responsibly.

It was an attempt to dump thousands of rifles the German Army didn't want any more. Some subset of the rifles got in the hands of dirty Mexican cops and were either used by said cops in support of the cartels or stolen on behalf of them. The impact is minimal and HK is not supplying the drug cartels.

16x16 TetraVex Solver updated (step-by-step visualization)
Hi everyone!

I have updated the solver I presented to you yesterday (16x16tetravex.xyz).

- Now it is able to produce a step-by-step visualization of the solving process. For this purpose, click on [Solve (step-by-step)];

- Today, during the conception of this step-by-step solution, I realized that my solver was in fact looking for ALL the solutions instead of one. I have corrected this issue: it is now at least 2x faster;

- The source code of the random puzzles generator is now online.

Thanks.

> New drugs come from universities, and from people motivated by the combination of public-spiritedness and academic success.

Ahh, hmm, I'm wanting to ask if you know anyone working on drugs without sounding rude.

In my experience they are like doctors. Lilly researchers do enjoy the thought of helping people, but mostly in the abstract. In the concrete they like complaining about people and regulation :) they also very much like living the "good life".

I'm not saying we'd lose all drug researchers if it were nationalized, but I do think we'd lose a lot of them -- at the end of the day, most people do want money, and end up being motivated to pursue careers which are financially rewarded. A full time doctors without borders just wouldn't work IMO.

As to the claim that drugs come from universities... You can take an interesting research finding and turn it into a potential drug... but there's a tremendous amount of work remaining, which isn't particularly interesting / researchy, and still requires someone very smart to do it. Essentially the more financially motivated people in academia are the ones who volunteer for what is often a fool's errand (a failed drug). I think the "new drugs come from universities" position is also true in the sense that "biologists get degrees from university" -- but as others pointed out, that sense is true for all industries.
God, how is that marketing? Honestly, how is that just seen as 'marketing'? How did they justify even writing that sentence with a clear conscience?

This is just infuriating. This is just taking advantage of stupid/impatient people who will order to get rich quick, and not read anything about what they're doing. It's taking advantage of people, knowing full well they don't understand what you're marketing to them.

Seriously, think about the uproar if this were medicine; buy this pill to cure your cancer.*

*Pill doesn't actually cure cancer, but somewhere a doctor is able to help you with that.

What I don't get is this: the freemium pricing model is often used, but what few people seem to know is that selling below cost is also called "predatory pricing" [1] and it is illegal. And there are good reasons for that. So... why are we letting the market get ruined by this phenomenon?

Sadly these days it seems that anyone disagreeable is a "troll".

The thing about hitler/nazi comparisons is that it is more likely than not to be a "shooting twee-twee bird with AA cannon" comparison. So out of proportion to the topic that even hyperbole do not start to cover it.

But then the internet age seems to have lost all sense of nuance. There is no like or dislike, only love or hate, etc. And don't "you" dear claim indifference, that is going to really fan the flames.
Yes, consumers are much more willing to pay for content-driven services - after all they are mostly consuming, not creating. But if you observe niches and prosumers (who are creators), they are already paying for software. And niches can be huge on global scale: think about running, cycling, gym training. Or pets, dogs, horses. Investing. Knitting. Photography.

You are totally right that they are currently much more reticent to pay for software than businesses but based on my anecdotal observations, I think that the trend line is growing and accelerating. I also think that for consumer businesses, you have to be a bit more creative with your monetization models. Cost/benefit calculation of subscription model is an easy task for small businesses, but consumer spending has always been much more erratic in the physical world also, thus subscription models are not necessarily the best fit for consumer space.
> they aren't prohibiting operating systems, they _might_ be prohibiting installation of operating systems that are not approved on certain types of devices that ...

"prohibit installation" means to ban.

"operating systems that are not approved on certain types of devices that ..." means specific operating systems.

So, the FCC "might ban specific operating systems"; you've paraphrased what the title says.
I can send money via various electronic fund transfer systems that do exist, not just through credit cards. There even exist standards, like SWIFT, to do this internationally. So yes, banks can transfer in a very similar way as bitcoin.
That's a good point. It still costs far less than what they would pay a medallion owner, however. And they get a car.

The idea behind 'only revenue growth matters' is that if you have an exponential growth curve then the actual numbers don't matter as long as they are positive.

If you're making tiny margins on every $1 of revenue then you'll still be a billion dollar profit business quite quickly if you grow that revenue by 100% every week. $100 sales and $1 profit this week? No problem, wait awhile and soon it's $1 billion profit off of $100 billion revenue.

Whether this model is realistic is obviously very much up for debate. Just because you grow 100% for the last 50 weeks says nothing about what will happen on week 51 when the easy source of growth is gone but your burn rate has to increase further to keep afloat... Of course, with scale you might be now making $2 off every $100 and your profit is now growing enough anyway?

Either way, using any single number as a proxy (or even complex finance without understanding the operating market) is never going to give you a perfect picture of anything.

Sadly, there are also those lined up to take your job, after you 'blow the whistle'. And not even that far away - your old coworker, your intern, pretty much anybody that wants the job and rationalizes the evil into "the company is responsible, not me".

I refused, as a contractor, to create radio software that broadcast on a restricted band (ambulance). It was desirable in some markets where that band was repurposed as industrial use. Broadcasting allowed faster connections than monitoring the channel(s) until the base station was discovered.

I argued it was contrary to regulation. But "everybody else does it". I argued it was wrong to create interference on critical service channels. It fell on deaf ears.

Then I argued as a Contractor I'd be personally liable. They tried to cajole me into doing it anyway. I flatly refused. Begrudgingly they accepted my legal/financial argument. I was reassigned.

Another Engineer (employee) stepped up instantly and volunteered to make the change. In the same meeting. Without a moment's hesitation.

So, I'm not confident an appeal to our better natures will be effective here.
How is this not equivalent to a theoretical "The ATF Might Ban Specific [Gun] Operating Systems"? The ban isn't on the OS, the ban is on the gun (or in this case, high-powered radio).
I don't know, but you probably won't be able to put groceries from some stores in that car... unless said stores shell out 30% or something crazy.
I disagree - saying they might ban operating systems, with no context, leaves out the fact they're only talking about modular radio systems or software defined radio systems.

Edit: also to be clear, as another comment pointed out, this doesn't have any impact on test/kit equipment that is not compliant with FCC regulations anyway and requires a separate license to use - this is targeting consumer equipment. So I still think it's pretty misleading.

The rest is the fact that I think the article is wrong anyway :)

This was a really good article. I've never used a RTOS, but I'm getting into robotics and I'll keep TNeo in mind if I ever need one. I'm using bigger ARM systems capable of running Linux but I'm curious about possible performance gains from using embedded programming style on these powerful machines.
Wow, I didn't know this could happen. I've only recently started using Lombok for some side-project related stuff and this heads up comes at a really good time. Thanks!
Specifically, SDR kits are usually rated as professional and test equipment, which are not certified by the FCC. The OP is about consumer products and other FCC-certified products.
I'm only not one million times better off because I have other costs to deal with which are completely unrelated to the gas.

> The trick of direct marketing is not persuading people, it's getting in front of people who already want what you have and making it easy for them to get it.

Indeed. As we say in the software biz, find out who's already evaluating products in a given category and go after them. As lucrative as it sounds, the "educational sales cycle" is not for the young, the under-funded and the starving.
... Which is a massive amount of saved fuel!
You won't be able to succeed, regardless of cost or people.

The reason are a few words in your problem statement: "top quality" and "Windows or MacOS or Linux" equivalent. Successful products don't get built this way, where you shoot from the beginning to build something excellent and basically copy what counts as "excellent" in the market right now. The problem is that you're chasing after the current state of the art, but in the time it takes you to catch up to it, the state of the art will have moved forwards. And so on, in a Zeno's paradox situation. Eventually all your engineers will get disheartened and leave, and you write off the project as a failure.

"Nobody should start to undertake a large project. You start with a small trivial project, and you should never expect it to get large. If you do, you'll just overdesign and generally think it is more important than it likely is at that stage. Or worse, you might be scared away by the sheer size of the work you envision. So start small, and think about the details. Don't think about some big picture and fancy design. If it doesn't solve some fairly immediate need, it's almost certainly over-designed. And don't expect people to jump in and help you. That's not how these things work. You need to get something half-way useful first, and then others will say "hey, that almost works for me", and they'll get involved in the project." -- Linus Torvalds

If you want to write a new OS that has a chance of market success, you should pick one dimension that current OSes do a shitty job at. Security might be a good choice, or making it work on whatever embedded processors are in vogue with hardware startups now, or maybe give it 10x better performance when running Node.js application servers. And then let yourself suck in every other dimension. If you're building a secure OS, make sure that everything from the drivers to filesystem (if it even has one) to applications are ironclad, but let the UI suck or even omit one. If you're targeting hardware startups, make sure it works for their needs, but forget about UI, or networking other than Bluetooth, or running on x86 hardware. If you're making the fastest Node.js server around, optimize for performance, make sure it can run stock apps, but maybe the only thing it'd run on is AWS and it won't have a GUI or OS scheduler.
Terrible, misleading, ineffective marketing is still marketing.

Ditto. I'm from the north, U.P., and growing up unripe jackfruit (कटहल) was actually my absolute favorite dish, dry stir fried not the one with curry. Even in the U.S. we occasionally get the canned version which is generally Thai in origin.

It is extremely sticky, so the trick to cut it is to apply cooking oil in your hands and then cut it. :)

Interestingly I have never had ripe jackfruit.

That comic, in turn, is just another efficient mechanism for evading criticism instead of answering it: as if the number of people making a criticism, whether large or small, has any connection to how valid the critique is.

I can't imagine that Google is going to just accept this globally. As the article says, they can't possibly agree with this and then disagree with China or Russia on content censorship, and there's no way Sergey will allow that (nor a lot of other senior Google executives).

I think Google absolutely would "pull out" of the French market if it meant they could save the Chinese market.
Sure. And in fact, such blanket environmental legislation ought to be supported by Objectivists like myself. Even Rand agreed that collective legislation is appropriate to collective problems.

But my point was that, for environmentalists, harm to 'the environment' actually outweighs measurable harm to humans. Hence activities that provably killed a bunch of people are likely to merit a less stringent penalty that those likely in this case.
