A nice time to plug a lovely Bertrand Russel Essay, "In Praise of Idleness":
http://harpers.org/archive/1932/10/in-praise-of-idleness/

I think there are likely many organizational and societal benefits here not listed in the OP article. Many of the comments here seem overly focused a simplistic costs_savings = hours_saved - days_off equation.

Wildly speculative examples (for further research, if you will):
* As quality of care increases, healthcare costs diminish (actually mentioned in the article)
* Workers with free time are more likely to be informed citizens resulting in better policy -- yuge, broad benefits. Spreads the happiness.
* Workers with more time are more raise children that will contribute more to GDP (because, e.g., they have time to help with homework -- I'm not even kidding)
* Healthier workers remain in the workforce longer (adding more to GDP before drawing retirement)
* Healthier workers cost less to maintain (because they're healthier).
* Etc.

Do I know any of these are true? No. But I do know that this is a complex system. Measuring a couple things and thinking you have an answer seems silly to me.
It is ok if you aren't 100% productive sometimes.
Yes for both.
It was a bit of an eye opener when I saw an old NT 4.0 server again. I think it had around 500 Mhz and 128MB, i.e. quite a beast for its time. All clicks had immediate on-screen results, a real pleasure to navigate, felt like a 90FPS game. Same was true even for something like iPhone 3GS and iOS3. Nowadays processors are so fast that software doesn't need to be optimized much anymore, and this is what we got. Upside is we can soon have true cross platform GUI apps that are smooth everywhere - until the next big platform like AR comes.
But it asks for confirmation and almost always suggests more than one option. Although it isn't smart enough to remember what you chose and suggest this variant in future.
I really wanted salad fingers to pop out of my screen.

Thanks for that.
That explains it for food -- but you also always tip bartenders (just like waiters, essentially their entire income is tips, so stiffing them is just as bad), taxis, barbers/hairdressers and massage therapists.
How to better protect your IoT devices from hackers
I'm not the parent, but I'd probably surmise that images are usually encoded in blocks to allow the image blocks to be decoded in parallel.

If you're asking why they use the zigzag (within a block) instead of a Hilbert curve, IIRC (quite fuzzy on this, so take it w/ a gran of salt and verify) the reason is that it allows for better spatial encoding (imagine having a ripple in one corner and going out - that's essentially what you want to encode w/ your DCT). Using a Hilbert curve would preserve locality, but I don't think it would line up with the spatial distribution of frequencies in an image.
And what if the competition isn't fair already?

What if I just want to rent out one room in my home on the side, not as a business? Why, then, should I be subject to the same requirements as a huge corporation with dedicated multistory buildings, many more customers, staff, and so forth?

To me, it sounds like the taxi industry pre-Uber. Lots of questionable-value regulation created by incumbents that doesn't really hurt anyone in the real world when it's mostly ignored.

Great links! Thank you :)
No and I completely understand agree with you. If you look at the amount of fees and insane amount taxes US citizen pay on airfares though it seems quite reasonable that the Federal government might might use some of that for improving air travel by building smarter hubs in more strategic places.

Having bikes chained everywhere is a common sight in China and other developing countries -- even in developed countries where biking is a popular mode of transportation like the Netherlands.

This is less common in the US. I wonder if Americans will tolerate having bikes everywhere, like the Chinese or the Dutch do.
Try going for a run. You get some alone time, the exercise does you good and the endorphins released afterwards can ease the problem

I find myself more energized getting straight to work after a run.

I have heard that Electrons move about a millimeter second (although electromagnetic emanations propagate at the speed of light). This is allegedly the benefit of 'optical' computing.
"Shoot for the moon. Even if you miss, you'll land among the stars."

Funnily enough the moon is much closer than the stars. ;)

I think success is a matter of preparation, opportunity/luck and 'hard work' in the form of dedication when the opportunity presents itself.
> The entire computer industry, well, the entire technology industry is founded on compute power becoming cheaper each year.

No, we've just gotten used to it. So now, like any junkie with a bad habit we're going to have to get used to doing without that. Or deal with the increased electricity bill.

> The board of directors will respond to pressure from the investors (or get replaced), and will replace company leadership if needed to continue advancement in technology.

Company leadership being replaced is not going to magically change the laws of nature.

At some point even Intel investors will have to accept that there are such things as physical laws and nature doesn't care one bit about your quarterly earnings reports.
Personally, I prefer to miss rush hour on the other side of it ;)
> PHP ~6

Ah, you mean good old PHP 4294967289?
HH transpilation was introduced in 2010. Depending on when exactly you look in 2010, FB had between 350-600M active users (https://www.yahoo.com/news/number-active-users-facebook-over...).

Many websites don't ever get to 350M users, so it's safe to say that plain PHP will satisfy your startup for a long time. Also, PHP7 is pretty much on par with HHVM in real-world scenarios: https://kinsta.com/blog/the-definitive-php-7-final-version-h...
Naming schema reminds me of this encoding used to refer to variants of conway's game of life, where numbers correspond to the conditions by which cells are created/maintained/destroyed etc.

It's interesting to see games in their 'traditional' sense be abstracted to fundamental components which can then be used to codify variants. Gives me hope for the whole "modding/remixing" culture.
As others pointed out, it's an overreach to call this artificial intelligence.

What the authors showed is that by training standard machine learning algorithms (random forests, logistic regression, gradient boosting, and a shallow neural net) on readily-available signals from the medical record (e.g., prior diagnoses), you can increase the c-statistic from 0.728 to 0.764. These machine learning techniques are well-suited to the data set and the empirical evaluation is strong, so this work should really stand on its own without trying to brand it AI.

There is some very high quality work on artificial intelligence in medicine being done today. Google Brain published a validation study of a convolutional net to diagnose diabetic retinopathy in December, and Stanford published similar work but applied to skin cancer. NIPS 2016 had an excellent Machine Learning for Health workshop with several works-in-progress:

This version of Zelda is astonishingly great - very different to others in the franchise.

It's a completely free and open world, no grinding required, with simple gameplay yet with challenging layers that appeal to the folks with wanting more, a beautiful environment with amazing weather and climate differences and so on.
Above all there is no in-app purchases required. It's a reminder of what games on the iPad could have been.
You were lucky and unlucky. You have probably worked hard but you may also have been co-founder of a bad startup and lost everything. Or you could have gone bankrupt because of medical bills.

You definitely should work hard but by no means there is a guarantee you will succeed. You also need some luck.
More precisely, it is a big corporate hotel chain thing for those properties that are more likely to host business people who can expense the cost.

I second gitolite. It was great for preventing force push by newbies :)
What about Gitlab? Isn't that more popular than gitolite?
I think there was a question about that: they had some issues with two different standards and decided it was better to pick one type and use that at all locations even if they had to bring it up themselves.
Ah, missed that :)
I would think that, nowadays, reading and writing memory are major bottlenecks, too, to the extent that spending time decoding instructions can be a gain if it allows for a denser instruction stream.

For machine learning applications, I don't think the end game is to have complex CPUs, though.

Assuming that brains have managed to find more than a local optimum and that our understanding of them is somewhat accurate, ditching all those caches, translation buffers, etc. most of the bus bandwidth, and moving computation towards memory is the way to (eventually; we need to learn a lot before that's feasible) go for machine learning applications.

Does the brain even have instruction decoders?
None - you cannot get stuck in this game. And besides - we have Google these days of the really tough stuff.
I don't know enough about the US market to have an informed opinion, though there are a few differences I'm sure play a part:

1. Lots of different languages and cultures in the EU make it easier for startup airlines to quickly grow from their local base. So, for example, you see WizzAir and BlueAir competing successfully with Ryanair and Easyjet in Eastern Europe. Transavia from the Netherlands, Norwegian from Norway, Vueling and Volotea from Spain, Germanwings/Eurowings from Germany.

2. The population distribution in Europe lends itself ideally to the LCC model (point-to-point networks and sector times under 5 hours). We have lots of regional cities with sufficient populations to warrant basing a few aircraft and opening up profitable routes. That's why Europe has the densest regional/secondary route network in the world.

3. The LCC explosion really started in the early 2000's (despite Easyjet first flying in ~1995 iirc). It exploded thanks to a perfect storm of airspace liberalisation, cheap aircraft leases 'post 9/11', widespread internet adoption (so LCCs could cut out travel agents and GDS fees) and booming EU economies fuelling consumer demand for flights and travel.

The open question is whether or not Europe will see consolidation within the LCC market but I personally don't think it will any time soon. LCC passenger count is still growing at ~6%/year.

Curious about opinions about this model of interviewing?

I think a lot of software engineers are not good or simply afraid of presenting in front of others. It's one of the most common fears that people have. That doesn't mean they're not good team players and it most certainly doesn't mean that they are not good engineers.

One of the main goals of this interview process seems to be discovery of talent that doesn't do well on whiteboard interviews. I don't know if they have considered the amount of talent they won't be discovering, because these people are not good at presenting in front of strangers which are judging the quality of their presentation.
Assume the worst, that they will share every last detail with {any,every}one. Can you live with that? will it jeopardize your side income at all?

Proceed accordingly.
How do I interpret Missing BMI as a risk factor. In the ML: Neural Networks run BMI Missing was considered a top 10 risk factor. The body text said this about BMI Missing: "This study suggests that missing values, in particular, for routine biometric variables such as BMI, are independent predictors of CVD."

I'm having a hard time wrapping my brain around this concept.

Thanks
I tried two online vendors that were actively soliciting customers but when push came to shove they couldn't deliver. Right around the same time I ordered an FPGA dev kit and an NVIDIA board, solved the problem I was dealing with and moved on.

Still, I would have very much liked to play around with the 'phi'.

> Admittedly I never bought any myself, my employer picked up some 31S1P from a local server OEM for testing when they were massively discounted.

That's the kind of deal I was looking at too. Maybe they were massively discounted because they were already EOL'd?
That's fair, but it is a different issue from wages not being regulated.
No. JUST DO IT.
I found this incredibly interesting. I need to play with CBMC [1] sometime. I've always been fascinated by the idea of perfect programs, because so much of my time is spent tracking down bugs. And because so much of my PII and finances depend on software that is decidedly not perfect.

I would like to know more about how this works:

> The formal verification tool effectively runs this function with all possible seed values and checks if the assert() is violated in any of the cases. But it uses a more much efficient method to accomplish this than running the function

Or are the "prove_" functions some sort of DSL that don't actually get executed as ordinary C code?

Ok, I give up.

I ventured into this to try to show my fellow libertarians that most times we are our own worst enemy. We can find common ground and make progress without having to break out Hayek every five minutes. I still believe that, but I've had enough for one day.

"...I feel like you still, deep down, believe that the government has this secret cabal of smart people who are going to step in and, for example, sensibly define all of our products for us...."

No. I do not. I believe in consent of the governed, and making progress through reaching agreement on items that both sides can accept. That's it. Thanks for the chat.
I'm not really much of an insider, I haven't used a travel agent either ! I'm just a developer who has recently entered the travel industry :)

What I do think is that you're not getting much of a discount going online (and agencies get their own exclusive deals too) - what you do get buying with an online travel agency (OTA) (and I personally like) is more control, but at the expense of advice and experience. If you're comfortable taking the risk of taking wrong choices and like setting your own itinerary, online offers more "freedom". However, it seems that customers 50 and over value the agents' experience a lot. Personally, there are several things I would have missed if I booked flights myself: legroom, connection times, the fact that you need to have a ticket be the same "segment" to get protected if things go wrong - although separate "segments" can be cheaper, etc., and, most importantly, someone to call if things go wrong (as they unfortunately often do in travel), who will have more leverage with the supplier than a mere customer. Of course, there must be good and bad agents, as with all services. Also, agents don't make much money (if any) on air tickets anymore, they rely on hotel and cruise and other ancillary services to make their money (or a service fee).

I've been told that top travel agents are worth their weight in gold (and are paid as such!), the guys working for the Elite travel division make the lives of business and luxury travel a lot better, they know the arcane commands in the mainframe-terminal GDSs by heart and can do permutations that are simply not allowed in most web interfaces.
I don't think that's true, any more than thinking that everybody will be zombifed heroin addicts in the absence of drug prohibition.

If this is what our criminal justice system has come to, we have a lot more to worry about than just AI.
I never read an intro so well calculated to make me not give a shit about startups.

That's quite an insightful comment. Reminds me of an article about sea squirts who literally eat their brain once they are settled and have no longer a use for moving [1]

You tolerate cars everywhere, so why not?
Quite so. Hard work will absolutely help you advance in your endeavors, but if your hard work advances others more than it advances you - which is true for an awful lot of people - then you are being used and when your utility is exhausted you will be cast aside without a second thought.

This argument is not, as some have claimed, an excuse for apathy. Rather, it argues that accepting the prevailing socioeconomic norms is foolish for anyone who is not close to the apex of society. The level playing field and other such political tropes are false, there is abundant evidence of this, and anyone who tells you otherwise either lying to you or to themselves.
This could be a signal that people who don't visit the doctor often are more likely to develop CVD. It makes sense—if caught early, risk factors like high BMI, high blood pressure, and high LDL cholesterol can be treated and thereby prevent heart attacks and other cardiovascular events.
Here are some options you can take.
- If you work for someone, then talk to your manager about your issue and see if you can get a lighter work load
- Another option is to take some time off in order to address the issue
I think the point here is providing a simple, lightweight solution. GitLab encompasses much, MUCH more than repository hosting.

Does anyone know of a good AMI or Docker container that's got all this already set up, as far as it's possible?

(I know it doesn't look complicated, but if there's a decent "standard" already out there...)
oh ok. I wish your startup made it. If yes, could you share your experience so that we could learn more?
I whole-heartedly disagree with your conclusion and tone, but am up voting because it is an interesting question I've wondered about. At what point did these people say "screw everything I was taught, I'm going to spread disinformation and promote harmful policies to make some $$$"? While we've made lots of progress on the hard science aspects of preservation, I think the social science aspect is woefully behind
Intel Virtual Conference for IoT Developers
Nowhere in that article does he say that hard work doesn't matter at all.

>What I have learned in this short period of time is that the pervasive narrative of “if you work hard you will get on” is a complete myth. It’s not true and we need stop saying it. This is because “working hard, and doing the right thing” barely gets you to the starting line. Furthermore, it means something completely different depending on to which context you’re applying this particular notion. So much more is required.

If you note what he says at the end of that paragraph, it becomes obvious that what he's trying to get across is that you absolutely need hard work, but that will give you only the bare minimum to have a chance and it's definitely not a guarantee that you will do well.
nope. Even though we were referred to YC.

This is an absolutely great maxim for people who are fortunate or wise enough to be working on developing their own abilities and position.

That's nowhere near 90% of Python. It's strange because everyone thinks Python is an easy language to learn, but that's not True at all. It's easy to pick up and be productive with it in a very short time, yes, but the interpreter has so much going on you can't learn everything in years.
If you happen to learn everything about protocols, the interpreter gotchas, there is the standard library which is also huge, and if you got everything in it, there is the ecosystem, which is so large nobody can know about every package. And I did not talked about the whole new world of Python3, asyncio and the whole old world of Twisted.
