I've taken a very different path to a smart home - and I don't have any regrets. First - the house was built as any dumb-house would be - 3 and 4 way switches really are, with copper in the walls. I wired for alarm, but didn't bother to hook it up right away.

What is working now? The alarm is connected to a raspberry pi so I can hook into it. Now it arms/disarms at a set time each day so I don't have to remember to do it. It can text/email me when states that I care about have changed - like when the power is out, or the alarm goes off.

Z-wave - for a few light switches that really matter to me, mostly outside lights. Most are on a cron job to do what I want, but a web UI lets you take control.

Wi-fi thermostat with an API - no 3rd part website needed. Why can't they all be this way? I can turn the system off when I'm out of town and fire it up before I get home. I also wrote some stuff to log usage each day along with the weather. Adding the alarm system status with the HVAC status and it will text me if the A/C is running and a window is open.

Garage door, custom GPIO hack to the opener. Now with the alarm status it can make sure it is shut each night. I can open/close it from a web page, but that is rarely used.

Alexa skill - this is the latest piece and the only one that needs Internet to keep working (except sending email, of course). It ties into all the other pieces and gives voice control to the parts that make sense for me. I won't let it disarm the alarm, I just don't trust a 3rd party to do that.

I pieced this together so I could learn and have something to play with, but now it is just nice. The best part is if something quits working, I'm not left in the dark like the guy in the article - I just have to get off my butt and hit the light switch or walk out and open the garage door.

I have something against smart home stuff that requires the company to stay in business and keep their servers up and running, but that comes at a cost - I have to roll my own. At least I know who to complain to when it is broken.

I messed around with writing OSes when I was around the same age, and I found x86-64 to not have much of an overhead relative to plain x86.

Getting into long mode itself is just a tiny bit of boilerplate at the very beginning. If you didn't plan on using paging then you need to do a bit more work to identity map everything, but if you already did the extra virtual address space means you can just map all physical addresses (that are hooked up to anything) linearly somewhere and not have to play games with mapping/unmapping things just so the kernel can access them briefly. You lose the ability to have the processor save state on context switch for you via the TSS, but that's not very hard to do yourself either. The ins and outs of running something in compatibility mode are quite complicated, but there's no reason to involve yourself in that if you're writing your own toy OS.

Overall I'd say 32-bit dodges a few things, but I wouldn't call it much easier.

Their best goto-market is probably licensing and embedding in various existing consumer devices: battery-less TV remotes, external temperature sensors, cyclometers, etc. Otherwise, distribution and advertising becomes an uphill climb to typical startup doom.
Wow, I love the randomness of coincidences like this.

I got to know Anders over 20 years ago, he was clearly crazy intelligent, and great fun, because he would always go off in funny what-if scenarios. Checking his blog confirms that he's still doing exactly this, and still thinking very hard about it. :-)

Why not rent and move over? I'm guessing you also work over the hill, the savings in your time would be worth it.
Most of the neurogenesis studies are done in rodents. So the conclusion should be carefully taken, especially for something like neurogenesis which varies wildly across species.

Running promotes neurogenesis, but also enriched environment, many drugs, genetics etc. Its effect in mice is also somewhat elusive at this point: we aren't sure whether it promotes learning or forgetting.

That being said, all the nice cognitive effects from exercise probably all due to endorphins (literally endogenous morphine) released in the brain afterwards.

You misinterpreted me. I was saying that digging a hole is the classic _useless_ project.
Hmm, I remember the design from a year or so ago if I'm not mistaken and it seemed the same.
How much did you invested on this project at real business figures? I mean, if you invested 100 hours and you choose an hourly rate of $ 100, you ended up investing $ 10k and a $ 10k is pretty low.

How much does this large company should invest to implement your side project themselves? This is another number to take into account.

If you ask me, $ 10k is nothing, it is the price for a less than two weeks custom project without too much negotiation, far from acquisition price, also think in all the work you should done to close this deal (including lawyers).
Google has weathered those same issues just fine.

In my experience, the success rate is a lot higher than 0.01%, I'd guess it to be more in the 5-10% range with a little due diligence applied to the idea and its founders. That's a pretty good bet/gamble for three-letter-title founders and anyone with equity north of 1% for the remainder of this boom cycle.

But I agree that startups are a terrible proposition for those with 0.5% or less, which is a matter of choice for the employee who could go get a higher expected return from any of the big tech companies for equivalent (and maybe even much less) time and work. This subject has been rehashed many times on HN.

As for society, um, the US (at least) is a "society" composed of many people who treat buying state lottery tickets as a retirement plan. MVP startups IMO are far less toxic than that. That said, when I made a little $$$, the most toxic thing I encountered was several supposed friends suddenly begging me to fund their ideas because VC wouldn't. @#%$ that, I have plenty of my own ideas to bootstrap with my hard-earned cash.
~10 P/E is ratio for a well established, stable business - ones that maybe deliver 10% growth.

But FB is stabilizing - https://www.wolframalpha.com/input/?i=facebook+p%2Fe+ratio+c... - P/E is dropping even as stock is going up. Market is betting that in a couple of years revenue growth should stabilize.
There are real benefits to using x86-64 over x86, namely, x86 is starved of general purpose registers. There are many more registers available on x86-64.

Ask HN: Which technology/language learn to dive into CS even more?
As a software engineer in Web, I worked with many technologies over the last 10 years, from server-side Perl/PHP/Python to frontend with all it's fancy JS ecosystem.
Recently my wife started taking computer science classes in Community college, and I helped her with assembly assignments. I mean, I studied it in college myself, but all it got buried in everyday work.
I really enjoyed learning more about assembly again and it's helping me at my everyday work — making my mind more open and solve problems faster.

Which languages can you recommend I should look to continue to improve myself as engineer? Better based on own expirience.
Well I just thought that bolding certain sentences in the story which are important in the story would be helpful in keeping people engaged in a long story like this. But guess I was wrong, and I reverted back to normal formatting. :-)

Facebook comments have demonstrated that having your real name attached to your internet comments does exactly nothing to stop people from saying awful things. It's a moderate deterrent at best.
It triggered a paradigm shift for me. Many of us need our regular doses of exercise to feel good. Cardio is the most importance medicine for me. This discovery also made injury and aging a little scary in a new way :shrug:
That's wrong. It's not if something is being made, it's if something is being used. Nothing is obsolete that's still doing a job.
Dear Apple: Reproducible and Verifiable Builds
The article kind of glosses over the battle with System Enhancement Associates. As a sysop (long time since I used that word), ARC was extremely popular. Then PKarc came out and it generated files that were more compact but kept the extension .ARC. SEA's product couldn't unpack those. So their product got the reputation as the one that didn't work.

The lawsuit was extremely unpopular given that they were both shareware products and the older, more established company was suing the company with a better product.

It wasn't clear now or then what else SEA could have done.
There's always the possibility he would have lived to 100 without taking vitamin supplements, but that's probably not the way to bet. In 1980 only 2.8% of the population lived to be 90, and longevity numbers skew female.
How could Uber have negative gross margin? I have a hard time believing that.

I guess it depends on what they include in COGS.
I think this pretty much depends on where you live. If you get enough sunlight on your skin then there is no need for vitamin d supplements.
Because "please wait while your lightbulbs perform a firmware update" Because you can't secure that shi... stuff? Because why?

But who will build it? The article hints that Intel (KNL) and Nvidia(+IBM) are not the front runners.
> You're not going to get skin cancer in the 10-30 minutes of sun exposure required for daily vitamin D.

Different people's skins have different sensitivities. Also, skin cancer doesn't happen in one exposure; the risk builds up over time.

> Stop clinging to that as a reason to shelter indoors and replace life with vitamins and manufactured meals.

Stop making assumptions. I personally have dark enough skin that a reasonable amount of sun exposure doesn't bother me. But that apparently didn't stop my vitamin D from being low (see my post elsewhere in this thread), so evidently I am dealing with the other thing I mentioned, the fact that your body's ability to make vitamin D from sun exposure decreases with age. So I started taking a supplement. Would you rather I just let my vitamin D be too low no matter how much sun I got?
Not quite the first! I actually had a Surface RT, and for a while you could jailbreak it and run Win32 apps, as long as they were recompiled. Obviously there wasn't much available (turns out there wasn't much motivation for recompiling apps for the tiny fraction of the tiny fraction of people with jailbroken Surface RTs, whoulda guessed), but there were a few: someone actually ported the Python runtime. It worked great!

It was always inexplicable to me that Microsoft did all that work to port the entire OS to a new architecture and then roped it off and said "No touching!". Looks like it finally wasn't a waste after all.

Edit: My bad, the title specifically said ARM64. Will leave the story up as a hopefully entertaining anecdote though.
How many hours have you put into it? Multiply the number of hours by $100.
Out of curiosity, what would the tech stack look like?

What I was picturing was:
- LCD display
- Patterned IR image projected onto eye
- Camera to read IR image on the back of retina, to figure out current focal length of cornea
- Realtime chip to adjust LCD display based on focal depth, to simulate light field image.

... The real issue is that response latency would have to be <10ms probably to avoid being disorienting.
I forgive him but this is what I received if you're curious (about 15 emails across 2 accounts within a couple of days):

"good stuff is out here on the dangerous part" - true words, and I believe if you keep on learning new stuff and making yourself better its not that dangerous anymore :-)
I'm not knocking anyone that talks about emotional pain as a reason to drink, but I want to offer an alternative theory alcoholism based on my experience. Many if not most people have settled on the theory of escape from a painful existence as an explanation, including many alcoholics. I've been battling alcohol since I was a teenager and now I'm almost 60. I've been in and out of rehab, lots of therapy and psychiatry, lots of sober time, a family with grown kids, a successful career and yet my most recent relapse almost killed me. More on that at the end.

Alcoholism is beyond thought and emotion. It operates at another level. It takes Kings and Queens. It takes happy family men, while often skipping abused children who grow up to be unhappy adults that can't hold a family together. It takes spiritual and religious leaders such as Alan Watts. The list of great, productive and seemingly happy people who are destroyed by alcohol is a long one.
My theory is that is a genetic glitch that allows alcohol to get hooked into the autonomic nervous system. It's telling in "Leaving Las Vegas" a woman tells Cage's character to quit drinking and he replies "why don't you tell me to stop breathing?" Carl Sagan liked to talk about our reptilian brain. That's the way I look at it. When the lizard brain wants a drink, it's going to get a drink. Luckily for me, it's not all the time. The urge comes and goes (sometimes for years.) The gene seems to run in families. If it is cured, my bet it will be through genetic therapy.

I'm not saying that resolving emotional issues doesn't make it easier to stay sober. Many things make it easier to stay sober. Sometimes I just go somewhere where I can't get it. That helps. It's why a lot of guys stay in the Navy. They have productive sober time at sea. Finding other activities and diversions certainly help. I like to program. I've often stayed sober by programming.

My last relapse almost killed me because I'm finding as I have become older, my ability to fight it is greatly weakened. On top of that, I go into a trance-like state where I stay I will stay drunk for days and weeks at a time unless someone who knows me intervenes. That is terrible on the body and as the body weakens, the ability to resist weakens. The downward spiral can be quick and brutal.

> No, they don't. That is a specific case, wherein someone could arguably publish data, because it's public.

That is my point. Much as you may wish it to be otherwise, your home address is not private information. Quite apart from the fact that you are required to publicly disclose your home address under certain circumstances, anyone who knows your home address is free to publish it if they want to and there's nothing you can do about it. Not even RTBF changes that.

> It would be trivial to change that law

Yes, of course, but so what? Unless and until the law is changed, it is what it is.

> you have a 'user agreement' with Google

I may have granted Google a license to use my copyrighted material. I have have even signed my rights over to them. I don't know because I don't use Google Notes, so I haven't read the T's&C's. But none of that matters because the initial state for any content I create is that I hold the copyright, and so if I want to control its distribution I can. There's no need for RTBF.

The only situation under which RTBF is applicable where existing law is not is when someone wants to remove true information about themselves published by a third party. (If the information is not true then libel laws apply.)
And wouldn't most such people prefer a desktop anyway?

Well yes in terms of specs and performance, but you can't take that with you. If you do GPU work you'll really want a discrete GPU with a complete featureset. Some people were complaining about the new MacBooks having AMD cards, I presume because most DL frameworks perform best with (or in some sad cases only support) CUDA libraries.
BS. The "ethics" went out the window when the taxi cartels captured the regulators in the first place.

Don't want people to play a crooked game? Don't set one up.
A few simple use cases:

Remote heating control. Go on holiday, leave the heating in frost-protection maintenance mode in the winter, turn it on again at the airport. Come back to a warm house, but plenty of energy saved.

Sunrise/sunset lighting. I have the lights in my office set up to turn on around dusk and turn off around 3am if I haven't already gone to bed. This works so well I hardly ever think about it now. It also means the house looks occupied when I'm away.

Motion-sensing light switches. I experimented with these, but it's a harder problem than it seems. I set up a PIR switch in the kitchen, and being able to walk in/out while carrying plates/food/things without having to hit the lights manually is amazingly useful.

Problem is PIR sensors have a limited range and are easily confused by various domestic heat sources. I was going to experiment with multiple sensors and more reliable software, but got distracted by a house move. So that hasn't happened - yet.

I still think user tracking combined with light level sensors would be amazingly useful. Switches on walls are probably going to be redundant when automation really arrives.

Colours and such are much less interesting than having smart lights that work so well you only have to think about them when you want them to do something unusual.

Having said that, I have mixed feelings about voice control. I have Alexa controlling some of the lights, and I don't find it very natural. This may be an unusual view, but I think speech is a channel of emotional communication, and tone carries a lot of information.

It's second nature when talking to humans, but talking to machines falls into some kind of social uncanny valley. It's impossible to do it without being reminded that you usually think about tone while talking, but now you don't have to - so of course you still do, but think you shouldn't, even though you can't stop.

Gee I hope you can give those to your grandkids one day at that price. Why would you ever approach $1000 for simple lights and controls?
I don't get out of bed for less than $100k unless it's $10k for a local gig for a week.
