This is a great headline-grabber but I still see landing a man on Mars as being an awful long way off.

I heard Jerry Pournelle talking about this and he said something like landing a man on the Moon and establishing a lunar colony is an engineering problem. Landing a man on Mars is a science problem.

The difference? We can already do the former. it's simply a question of money and the will to do it. The problems are basically solved.

Landing a man on Mars has far bigger problems. The round trip (or even one way) journey with current propulsion technology will take an incredibly long time (upwards of 2 years). How do you keep someone alive that long? What about the psychology of isolation? Sustained radiation exposure is a real problem.

Personally I see manned spaceflight, particularly to other planets, as being largely a propaganda exercise until:

1. The cost of lifting into orbit (per kg) goes down. Way down. Like 2 or even 3 orders of magnitude; and

2. We have a much faster means of propulsion to make journey lengths manageable.

(1) is probably the easiest to solve. SpaceX's launch prices are actually quite low (but those are fairly low orbits; launching to another planet is more expensive). Virgin Galactic and other private suborbital efforts will (hopefully) lead to a dramatic cost reduction of getting into orbit.

(2) is a fundamentally hard problem. Ideas such as solar sails and the like are far from being practical (plus with a solar sail, how do you get back?). Magnetic fields as solar sails is an interesting idea but has a whole bunch of other problems.

Otherwise you need to eject mass to give you velocity. That mass is something you have to carry. The more mass (fuel) you carry, the less effective each gram is (in delta-V terms).

What I think will probably drive this is the coming earthbound resource shortages (inevitable unless we drastically reduce population; it's simply a question of when) that will drive a permanent presence in space. Once you have a huge industrial manufacturing capacity in space, the economics completely change.

EDIT: I agree with other comments in that a one-way (colonization) mission makes far more sense but I'm still unconvinced this will happen anytime soon, probably not in my lifetime.

Mars does have some interesting properties though if a colony can become self-sustaining:

1. Lower gravity. This actually makes the idea of a space elevator far more feasible [1]; and

2. Mars has features that extend beyond the atmosphere. The atmosphere is ~11km thick. Olympus Mons is 25km high.

I've read seemingly informed speculation that if we (the human race) had evolved on Mars, we'd already be heavily spacebound since it would be far, far easier.

This is what might justify colonizing Mars. Not that that is an easy problem.

Looks interesting - snagged dis.co.vu, now I just need a startup for it or something.

Just two minor issues, though: the option to remove a domain seems to be missing, and it's not clear that the free domain limit is 2. But everything else's peachy.
Keep in mind that the map software itself was created by Apple. Also keep in mind that there is almost certainly some sort of SLA/contract ensuring continued access to Google Maps data for some time period, and that it would not be particularly impossible to switch to, say, Bing-powered map graphics.
No near-instant confirmation, maybe. At first glance not a big problem for users, but can run you into a lot of problems

It is not. Educate yourself.
Define "few years". If we put some numbers and suppose after taxes and not living in their car or on the street, OP is able to save $150k a year. That would take just over 13 years to accumulate the $2M. A bit less if 7% annual total market returns continue. $70k is a modest investment income, definitely won't provide the lifestyle OP was enjoying during the accumulation phase.

The games rigged; even a top earner like OP can't break into the lowest echelons of wealth and lifestyle by working for a living.
Chart 1 is interesting. It shows "labor input utilization" (that is, how much people are actually working) finally almost catching up to long-term trend after the 2008 crash. Maybe now we can get some wage inflation!
Wait what? The secondary market value is why people are willing to buy new cards, it lets people justify spending a lot of money on new cards.
> I will often get "fingerprinted" with a very valid browser, then continue my work after treating their site as an API; ie: talking directly to the backend (or rendered HTML page) and no one else.

This seems like just the kind of behavior that an ML approach could easily identify. Even just feeding a trained model your basic request log data would show you as quite a different kind of user: you're not fetching images, javascript, etc and would have a substantially different traffic profile. Obviously you could get around that by scripting a browser, but that just kicks the can down the road: a scripted browser will still likely behave in some measurable way different than a human-driven browser, and the specifics of those differences are unlikely to be found by intuition but rather by ML which can hone in on things we wouldn't think of. For example, the time spent in certain pages/activities, or the position of the cursor on links being clicked (when you tell a headless browser to click a link, do the mouse coordinates in the click event look normal or are they at the upper left coordinate of the link's position?) etc. The more data you feed such an approach the more details it can use to find anomalies that differentiate humans from bots.
Hurting the bottom line just means the workers get shafted (pay cuts or layoffs). Even with a fine shareholders still get their dividends.

No, to really drive the point corporate officers need to go to jail.
This means you could advertise roles only for people over 40.

True, but I have never seen this once in practice.
One design decision that comes to mind is Muon's significant whitespace. Having that makes it much easier to do parser error recovery, which in turn made it easier to build the language server. Another one is that I initially had the rule that all typenames had to start with a capital letter, and nothing else could. Which simplified parsing even further, but turned out to be too restrictive, so I got rid of that. Your question is something I've wondered about too. How can the design of a language co-evolve with its tools? If you have pointers to existing research on this I would be interested to learn about it.
One way is via Photomultiplier http://en.wikipedia.org/wiki/Photomultiplier
essentially the photoelectric effect is used to create a cascade of electrons, the created current can be measured and related to the energy of the original photon (which is h * f, where h is Planck's constant and f = c/lambda is the light frequency.)

Why? Just because the criminal could be from India and you’re from there too? There is no need for shame; you are not responsible for the actions of everyone from your country.

Increasing cycle count (and thus, battery life) of all big batteries by 33% would be a huge deal though.
How would it be possible for them to not manipulate results? The very definition of a search engine is ranking and filtering sites based on a query.
The point is we don’t know. We will never know which new knowledge is created and which new problems will be caused. But only by allowing open and free trade of ideas will we be able to quickly solve them.

But to take your point and run with it…why is “because it’s ethical” a worthy goal? That seems to be circular reasoning, and also relies on one concept of “ethical”. How do we define what is ethical?
Hi Chris,

Not sure if you are asking a question or not.
To clarify, my understanding is that there is a greater risk of death when detoxing from alcohol,although it is possible to die from benzo withdrawal it is not as common. My information comes from registered nurses who worked in Rehabs, and years of interaction with a lot of ex-drunks. I did a very light search last night, but did not find anything that gave good comparisons.
> If you pay the California rate then you will be putting way more money into salaries then needed, which could drown your company in hard times.

This doesn't follow. You can still be profitable by hiring people who add value, and paying them a consistent percentage for that value, regardless of location. Assuming of course that everyone is working remotely regardless of location, and time zones are a non-issue. (remote vs. local could have legitimate salary impacts, as well as time zone availability, due to potential increased burden on the business).

If your business's profit is based on the ability to exploit reduced living costs, then your business is at least partially focused on trading in salary differences (arbitrage?). That has it's own problems (like splitting your focus), but is probably OK as long as the margin you're making from it is lucrative. As this margin decreases you're spending more and more time trading in salaries and less time focus on your product. That's perfectly fine business wise as long as you're still making a profit, although at some point you may turn into an agency / recruiter (pivot?!?).

If however, your business's profit is based purely on providing a valuable product, you still benefit from a much wider pool of talent (thus reducing overall salaries due to supply) even without exploiting living costs. You can ignore location (assuming again time zone isn't an issue) and pay based on percentage of value. Plus you can still focus primarily on your product, instead of becoming a salary trader!

You are right about being able to predict either, but the specific quantity described in A is the slope, while in B it is the inverse of the slope.
You're assuming macro-economics is concrete, peer reviewed science. Lot's of people disagree. The great depression lasted way longer than it should have because of the anti-deflationary measures put into place, like slaughtering millions of livestock to prop up commodity prices while starving, out of work people looked on in horror. If prices had been allowed to fall, wage rates could have come down to a price where hiring made sense.

Read Rothbard's "America's Great Depression" for a good overview of the case against macro-economics and deflationary interventionism.
That entirely depends on how you use the data. If you store files that are accessed over the general internet, and each file is downloaded just once in the month, you've just quadrupled your monthly cost, thanks to AWS' high data transfer fees.
Thats a sacrifice you make when you choose the ios ecosystem. It's a compromise between secure apps, privacy and inconvenience.

Very nice work. I love hardware based projects. Regarding the FPGA isn't the Lattice ECP5 FPGA too costly for a personal project?

> The end project is a low cost combination signal generator / oscilloscope for aligning antique radios that I eventually want to sell.

What do you mean by aligning antique radio? Could you please explain a little bit on this?

Are you using lattice tools to build or open source tools?

Also is it similar to Red Pitaya board?
We don't have anything that kills the virus but doesn't kill living tissue as well. Pouring alcohol over your hands is fine because skin evolved to protect you from a harsh environment. Pouring alcohol over mucous membranes is a very bad idea.
I'm building a community for knowledge sharing (www.sivv.io). The idea is that people use this to share and discover short, structured summaries of useful ideas, knowledge or advice that they come across in the books, articles, podcasts etc that they consume. This allows people to learn more while actually reading less and is currently focused on the following topics:

- Business
- Personal Development
- Professional Development
- Behavioural Science
- Science & Technology
- Wellbeing

You can sign-up to the beta version at www.sivv.io - we are publishing new summaries daily. Any feedback would be very much appreciated - feel free to message me at info@sivv.io. Many thanks!

It very much is. When you are limited in every way you have make some cuts. This is just the cut that says that it is probably covid if it is not flu and they are from an area with test confirmed cases. And in by far most cases it is going to be correct. Probably as correct as the current test for covid.
Yes, she is a saint.

Whatever doesn't make you immortal literally can kill you, even if you do other things.

I totally forgot about that! I used to give them 1600 Pennsylvania as my address. I was bike messenger at the time so I knew all the good addresses in DC and would give them all the big federal buildings.
Call overhead would be nil, since it created the function, and thus it does not have to follow normal argument passing behavior :)

I really don't recall, but I'm guessing it was a major update. I believe this because I think I remember it being for the newer phones (iphones 4/5?) and that the update didn't include certain features on the 3g (this was a while ago for me, so I don't recall many details, sorry)

But at the same time, there was no "Warning: This will actually slow down your phone and make the user experience suck." I'm okay if a phone can't support certain features that the latest model includes. But the fact that an update actually made my older phone worse off, was quite the disappointment.
Thanks for the heads-up. It is a good way to get more, relevant information quickly.

But given that the link is an hour-and-a-half long, and that article is quite brief, it would be more accurate to say that he's filling in some of the content of his presentation with some-of-up-to-all-of his article. (But the link must have a lot more than what's in the article.)

I may listen to all of the presentation in the near future, on the chance that he will have something fresher and newer to say than things he's already said about his "war on general-purpose computers" thesis.

I appreciate him spreading such messages.
The current system isn't simple. The H1B is only one non-immigrant visa category. There's an entire alphabet soup of other categories, and that's not even getting into the permanent resident visas.

I certainly agree that the system could be rationalized, I've got a lot of my own ideas, but most reform in this area must pass through Congress. I've been paying attention to this issue for over a decade and half now, and one thing I've learned is that there isn't much enthusiasm on either side of the political aisle for major changes to the legal immigration system. Every once in a while a strong lobbying group will get a tweak or added numbers to a particular program, but the real political interest is the stock and flow of un- and semi- skilled workers from Mexico and Latin American.
Does anyone have an idea of how much a real-time tracking package would be to mount on airliners? It seems like an Iridium modem transmitting GPS to some location every 15 minutes would do. It just seems like this should be a solved problem.
There's also 50,000 annual "diversity visa" immigrants from countries with low immigration rates to the US.
There's a huge "purple squirrel" problem. Employers expect to be able to hire someone who knows Drupal, PHP, and Ubuntu. They don't want to retrain someone who knows Methode, Java, and Red Hat, even those do the same job.

Few employers have the capability to train any more. Whenever you encounter an employer whining about this, ask them "How many people do you have in offsite training right now?" If the answer is zero, tell them you've found their problem.
This is an excellent modern example of the tenacity of humanity.
Well, this is a boring answer but I love my 2013 15" MBP. I use it every day for work and non-work purposes. It still feels and performs like it did when I first bought it, never had it in for repair. It's really been a tremendous value.
But do you care if they gamble away their money? Surely, with the "fraudulent means" example, you care about the fraudulent means, not the money. Can't comment on the 401k thing, but I suspect a conspiracy theory. If you have proof of people buying legislation, maybe tell CNN?
My biggest challenge as a CTO is that, by nature, I'm singular in focus. If I am developing something I find it hard to context switch and review other developers' work. The best strategy I have found so far is to block certain times in the week solely for reviewing everyone's progress.
Yes. If generated from renewable sources, power should have a reasonable cost so people aren't server bitcoin mining or indoor weed farming for pennies when power is a limited resource. Prices should be smoothed out and predictable to the customer.
I don't love ads, so if you goal is to just not have ads on your product, I get it.

We had the same choice on Read the Docs, but didn't really have any other way to make money. We decided to build Ethical Ads, so that we could be proud of the ads we show, knowing we weren't adding to massive pool of data out there. I talked a bit more about it here: https://www.ericholscher.com/blog/2016/aug/31/funding-oss-ma...

We talk about what ethical advertising is here: https://www.ethicalads.io/advertising-vision/ -- and if you're building a dev-focused site, know that you have an option if you want monetization without sacrificing your values.
I tried to run it on an old 32bit pc with Linux. But it complained about not knowing the format of the executable.

As someone who lives in rural Georgia/almost Alabama...trends I see here are people having "barn houses" built for them or using some of the huge prefab outbuildings from Home Depot/Lowes dropped on a piece of property and starting with that. The "barn houses" I am talking about are current tech barns built with 2x6s and galvilum (galvanized aluminum) for roof and walls. Generally take out a barn/land loan and then have interior slab and subs come in and turn the interior into a home. A home permit would not allow such an inexpensive build and if tax assessors only come around every five years provides a significant savings...generally 10-15k over those first five years.

This is an incredibly offensive and insulting comment about people you don’t know, regarding software you openly state you don’t use on a daily basis.

I would care a lot less if we were talking about billionaires building commercial startups, but you’re literally attacking open source contributors. Moreover, my personal experience in using LiveView and interacting with the community has been the exact opposite of yours, so I find your comments to be totally misleading for people who might think that your walls of text have any nuggets of wisdom in them.

I’ve tried a lot of open source software that left me thinking, “wow, what a waste of my time.” For some reason I never felt a need to openly attack the authors of these low-commercial-value-for-the-creator, volunteer-driven projects. You might want to consider directing your critical eye toward the actual problems in this world, rather than volunteer programmers’ projects that didn’t met your personal, highly-opinionated requirements.

The parent comment is Exhibit A for why so many people refuse to get actively involved in the open source software scene, and why so many drop out.

Is there something wrong with being addicted to information?

Is that not the single thing that ties us together? Knowing this and that; then using that knowledge to connect to others? Maybe I'm missing something, but is there ever too much information?
I've been thinking I need to move up to Boulder rather than being down South of Denver, but doing so would be counterproductive since I still have another job aside from working on my product. Moving that far north would mean 2 hours a day wasted in commute, so I'll probably just live with only going up that way a few times a month for meetups.

As for the other advice, my thanks to all who responded. In the mean time, I'm going to keep trucking along working on my product and hopefully the right person will present themselves through some of the networking options that have been recommended.
No he said its easier to get to market without VC it removes VC's from "early rounds". The need for VC to grow is still going to be needed for the vast majority of new businesses.

"This effectively removes VC’s from the equation at these early rounds and turns things over to angel investors"

Even then the point still stands even angel money is still easier to get in Silicon Valley.

Wi-Fi is power hungry because it's always on. It seems like these little buttons would only need to connect when you press them, then shut off right after. It's a very minor power draw when you consider the wi-fi will only run for 15 seconds every month or so. Of course, that's my read on it - maybe it does connect to the Echo.
