Many people just enjoy their workouts. Of course there is a small number of obsessives in any activity. Of course there are people that hate working out but just want the result. But from years of experience I can tell most people just feel good both during and after their gym visits.

im using slack at work , and why should i use IRC or XMPP
with slack ? and why it is so bad they cancel it ?
realy.. its just tool .. why i need IRC on top of that?
Now that's a competitive edge...
This was in fact the business of the infamous Color startup[0]. For those not familiar, they raised a ridiculous amount of money, then shut down and returned most of it to the investors. My favorite memory of Color was when they became a landmark when they bought a massive office in downtown Palo Alto, got hit with zoning restrictions which forced them to use the ground floor for retail or leave it empty (they left it empty).

It's possible to judgde the relative positions of the photographers by eye based on some of the waves directly under the lighthouse. In Eric's picture there are some distinct crests immediately below the lighthouse door. In Ron's picture the exact same crests are on a diagonal line from the door toward the lower left corner of the frame. Tracing this imaginary line "out of the picture" would lead us to Eric's position, which means that Eric is to the left of Ron.
Do you know this wouldn't have an effect or do you guess it wouldn't?

In the end, support chrome is simply supporting another Internet-Explorer-era. Maybe not as IE but it would be very similar.

> but suppression of dialects was never a major part of the campaign

From the article:

The initial goal of the campaign was for all young Chinese to stop speaking dialects in five years, and to establish Mandarin as the language of choice in public places within 10 years.

> Hokkien is still spoken by many Singaporean.

Again, the article shows that in 1980 81.4% of Chinese Singaporeans spoke a Chinese language at home that wasn't Mandarin. In 2015 it's 16.1%.
Ask HN: Why use Redis?
Why not skip network path completely and use in-process, embedded instance which still does replication in the background.

I love Redis but I prefer all those, GETs are not sent over the network each time I need that data.

Is anyone aware of such implementation? We are using Rust and Go in our app.

In a medical context, double blind means neither the patient or the doctor knows if the patient is receiving the drug being tested or a placebo.

I'm not sure how that would work for software, but it sounds like a much larger experiment than is currently customary.
Let me give you an example. While I was furniture shopping for my house, FB showed an ad of a nice boutique furniture store which opened less than a mile from where I lived. Since this was a new store, it had no Yelp reviews and had no word of mouth references. I visited the store and absolutely loved and bought a number of large items from there. I believe this is a positive development and these ads, at least to me, are a lot better than some of the non targeted things I see.

Wasn't he shooting continuously for 45 minutes? That's 3% of a day. Wouldn't he have a shot of the same millisecond of any photos taken during that time?
Sorry but I do not agree at all. First, the fact that they chose the same photo might not necessarily mean that photo is the "optimal choice" according to some algorithm: it can perfectly be a coincidence. I find it even more improbable that a tool that selects "the best photo of a bunch" is useful for a significant portion of the photographers (as in "it gives results according to their tastes") unless it takes into account only basic measures and they can use it in specific instances (e.g. find the photo with the best light exposure).
Amazing! Programmers are needed in each discipline. This is such a transdisciplinary project.

Did you read my comment? Progress is awesome and inevitable, but how we deal with it and how we deal with the people who's careers are made redundant by it is what we need to discuss. We need to give people options, whether that's retraining and financial support, universal basic income, or whatever. Currently the money just goes upwards - the progress, innovation are owned by the elite as intellectual property. We need to find a different way where the fruits of this progress are distributed to benefit humanity as a whole, not used to further exploit the masses.
Flatiron Health was just acquired by Roche for 2 billion dollars. A few years ago Flatiron purchased a company called Altos Systems and as a net result acquired an EMR and patient data for 20%+ of cancer patients in the US. A major part of Flatiron's business was de-identifying patient data and flipping it to pharma companies. They do contribute to some FDA studies and submit papers here-and-there, but the largest sources of income are the EMR and pharma, pharma, pharma.

Are you really comfortable with one company owning so many parts of patient care? I'm not.
Our VR surgical training startup has been working for the last few months towards a big medical conference this week where we're showing multiple training procedures for multiple customers on Oculus Rift, as well as having our own booth. The headsets all stopped working the morning of the conference.

Fortunately one of our engineers figured out we could get our demo rigs working by setting the clock back a few days. This could have been a huge disaster for our company if we hadn't found that workaround though. Pretty annoyed with Oculus about this
So the alternative is stop FB from targeting you so that you get less relevant content?

I spend >30min of my time on FB. As long as I find relevant content (which includes ads) I am good. I am not saying FB is the best source for all to find content but I do like to see updates from my friends and pages I follow and if relevant ads are sprinkled in between, I am a happy user.
I evaluated InfluxDB at my previous company. Settled for TimescaleDB in the end due to the querying power of Postgres.

Influx had some real quirks with nested queries (wrong data being returned). TimescaleDB is probably a bit slower and less compact but with our data (a few GBs/day) it wasn't our biggest problem.

A few months back I gave a Trader Joe's blueberry muffin to my son.

https://www.fooducate.com/app#!page=product&id=B7329F0C-B3E6...

As usual I cut it in half straight down the middle. As usual I paid no attention to cutting it. I was just about to hand it to him when I noticed something strange, so I quickly took a photo...

https://www.dropbox.com/s/8tjrwql37i7ujjn/muffin.jpg?dl=0

The chances of the cut aligning the way it did, the blueberries lining up the way they did, the cut cutting the blueberries exactly in half, the blueberries ending up in this exact formation, me buying this specific muffin, the rotation of the muffin when I cut it....

Well, it just seems impossibly unlikely for something like this to have happened, yet it did!

Correct, but there are about eight orders of magnitude more milliseconds than days, and you need another two or so orders of magnitude because not everyone is a photographer who publishes their photos. Then again, the internet is a medium that reaches many more people, which is not true of the average birthday. So one would still expect this to happen only maybe every few years.
It's made more remarkable IMO that they were two _professional_ photographers though, and that it's not just two snaps that happen to have the same timestamp, they both chose that moment to feature from the burst they probably took around that moment, the hundreds of other moments in proximity, and the thousands (I suppose? I'm no photographer) they each took throughout the day.

That's not how APIs work. You don't eliminate stupidity by thinking of each and every way the user could screw up. You simplify your API so there aren't so many ways to use it in the first place.
Nope, thanks for the tip
Any education discount? It looks like a good tool for teaching UX. Sketch and other many UX tools have education discount.
It's still Oculus fault because they didn't use a timestamped signature.

A timestamped signature on the binary would have it kept working and that's how MS intents it to work. You can leave it out if you have the desperate longing for having your software break suddenly without reason like Oculus just did.
> First, the fact that they chose the same photo might not necessarily mean that photo is the "optimal choice" according to some algorithm: it can perfectly be a coincidence.

Well, obviously it does mean that; the photo was the optimal choice according to the two algorithms used by those photographers to choose their picture.

Does that mean it would also be selected by another equally good or superior algorithm? No. But it does necessarily mean that the photo is the optimal choice according to two algorithms.
And what's the developer experience?
We do and we‘re still okay with it. It‘s an incredible piece of engineering of a database, all optimized towards a single use case:

Guaranteed single-millisecond reads and writes on a key-value store that‘s too expensive to fit in RAM.

That being said, nowadays it‘s hard to have a dataset with exactly these properties, and honestly they messed up all other use cases pretty hard.

Secondary indices are hard in practice, and so is any other structure, like sorted sets, or lists, or trees, or any kinds of analytics. They tried a lot of things (LDT) and abandoned them again.

Also, AS can be a diva at operations. The amount of brains and engineering within Aerospike is mindblowing, but it‘s like a F1 car: The fastest you can build, but everything is special and custom made and expensive to replace.

We‘re looking currently at Scylla, which is still decent at K/V (also thanks to recent hardware improvements), but wayyy more flexible from the data model side.

Count me as a single data point for the example of a teenager switching to paid Spotify as a college student (albeit discounted to half-price). When I graduate I'll probably keep paying, at the full $10/month. Apple Music is tempting for Siri integration, and Amazon and Google are certainly alternatives, but I'd rather stick with the cross-platform "underdog" that doesn't lock me into using iTunes.

Also, screw Apple Music and Tidal for "exclusives."
A person recreated from memory is still a fake, no matter how accurate you and your memory are.

And most people do boot have the skill to do a full character model at the age of 6. It takes special talent nature to do that even when old. That is even ignoring the fact that people change and adapt over time in hard to predict ways.

So this thought exercise is actually protecting your own wishes through the light of some imagined model of a person. Might as well use Tarot cards instead.

Skype for Business does. But... not the Azure/Cloud version; you have to host it on-site, and MS are rapidly replacing Skype with the less feature rich (if that's even possible!) 'MS Teams'.

Author here :) I used Apollo for the first time in this application, it was great throughout the implementation, but this was truly the worst part to implement. It came with multiple flaws in my eyes which are perhaps due to Apollo being in early stages or me just being inexperienced with it.

- updateQuery was a deprecated property when I implemented it and one should use update instead. But it wasn't and maybe still isn't possible to use update for the fetchMore scenario.

- I couldn't find any real consensus on keeping immutable data structures in Apollo. Since I favor to work with it, I kept it this way. However, in the case of pagination and deep nested data structures, you would have to fallback to a library to deal with it. Apollo adds their own immutable helper to the whole tech stack which means to adapt yet another API... I wouldn't want to do it and I think it's a bad decision to introduce yet another immutable helper. That's why I picked the object spread operator.

- I would hope that updateQuery goes away and one would be able to use writeFragement in the update property to update the paginated data. If it's possible, I would love to speak more about this topic with people more knowledgable than me in Apollo :)

The cost of subform is truly on the higher side. I understand that it's catered to a niche target group - how niche is it though? if it's managed by 2 people, 1000 customers would bring in $25.000 monthly before tax. I cannot imagine that they aim for 1000 customers only, though.
Similarly, I took German and French in school, and got quite good grades. However, I've not had much occasion to use either language since then. I did read some German news articles, so that part is sort of OK still.

I've been with my (German) girlfriend for about a year now, and have visited her family in Germany a couple of times. It has really made me realize how much of my ability to put together a sentence in German has simply vanished over the last 15-16 years. I'm boning up using Duolingo now, because I really want to be able to have a full conversation with her (not very English speaking) family.

The general consensus is that customers cost money -- not just in terms of infrastructure, but also support. Customers who do not want to pay, will never pay, but will still cost you money. It's better to aim your product at people who want to pay. Customers who want to pay will not baulk at paying (by definition). Freemium is a loss-leader marketing scheme. There may be other effective marketing schemes that don't continuously cost you money.
