Both firebase and appwrite are amazing platforms. I use firebase extensively at work, it works great and it scales.
The main problem with firebase is that you can't self host it, this means you can't easily test or replicate environments.
The emulators are limited: indexes are not enforced, copying the production database (no more than 50k documents) to my macbook pro crashes the emulator.
Also the DSL used to define security rules is not flexible enough. I've seen developers skip defining rules because they don't get it to work.
Appwrite is great and you can self host it, but it introduces concepts/APIs to query data and secure it that you have to learn. They also try to solve the problem for all platforms and languages.
JSDB tries to extremely simplify things and just use plain javascript for everything.
You should use JSDB if you love javascript.
That being said, firebase & appwrite are both production ready and JSDB is not there (yet!!)
I wish I had discovered Marcus Aurelius years ago. I would have had a much different life.
"Meditations" has definitely changed my life. I have learned to be more patient and to not let the small things bother me. I have also learned to be more mindful and to live in the present. And also how to effectively rule a global empire.
I'm surprised that it's only MacMillan and List for organocatalysis. There's plenty of others that come to mind, like Jacobsen.
Regarding MacMillan, his student used proline (which opened the whole proline organocatalysis area) and he said he had "no idea why she did that experiment". He definitely guides his students well.
To be honest this is one of the more real proposals I've seen for an Interstellar probe, and there are still many problems to be worked out as both the paper and the comments here point out.
I admire the optimism in the paper though, even if its misplaced. Maybe pooling together resources in the scientific and engineering communities to develop an interstellar probe system could give a working result, but there are some significant hurdles to overcome first. It would be a big project, taking many years to see fruition, but at the same time it could also be a game-changing development and a hugely inspiring feat.
Could we see probes in other star systems by 2075? I think its not an unreasonable suggestion.
Interstellar flight is an insane challenge. It’s one of the hardest things humankind can attempt yet still not beyond the laws of physics. That means you have to approach things from first principles and often have to invert the problem (“assume we manage interstellar flight by 2075. How did we do it?”, etc). It’s intellectually seductive in the best way.
I think it’s good to attempt such challenges, even if just conceptually, as it makes lots of other things seem a lot more achievable in contrast, sometimes almost laughably so.
I've always thought interstellar probes were kind of pointless. Even if the probe could average 10% of the speed of light, the amount of time it would take for a probe to reach its destination (all but the closest stars) and then for data to return at the speed of light is greater than the lifetime of anyone who wants to study. You'd have to send out the probe, hoping that your grandchildren wait around for the response.
Interstellar space exploration will likely be manned-only. As other threads point out, with sufficient acceleration, due to time dilation, humans can reach distant stars within their own lifetimes (at the expense of thousands of years passing on Earth).
Disagree. At 0.1c, it takes 42 years to reach Proxima Centauri (and 4 more years to get data back). The Voyager 1 and 2 probes are still operating and transmitting scientific data that people are interested in (the missions are still funded) and were launched 44 years ago and are likely to continue a few more years. So we have existence proof that people would still be interested in it over that kind of timeline.
And I know you excluded the “closest stars,” but I don’t understand why, except that it undermines your point. There are at least 3 nearby stars that could be reached by probes in a researcher’s (or at least their funding institution’s) lifetime vs just our one star system.
(Besides the 3 stars in the Proxima/Alpha Centauri system there are also at least 11 additional stars—including fusion-capable brown dwarfs—within 10 light years of the Sun.)
I disagree. It the same principle as sending something to the outer solar system. Many of the scientist who propose those things and work on the instruments and so on have long left the field by the time the missions arrive and many will soon after. Before the mission ends, a whole new group of people are working on it.
This is the same idea, you send a new an improved probe every 10-20 years and eventually you get data back and over time you have constant data stream from all kinds of different places.
> You'd have to send out the probe, hoping that your grandchildren wait around for the response.
Why would our grandchildren be less interested in interstellar exploration than we are? We need ways to organize (parts of) society for the long term, that seems way easier than inventing magical "accelerate at 1g for a decade" tech.
maybe a reason similar to whatever explains the drop in oceanic exploration among the peoples of south-east asia and polynesia several thousand years ago?
Doesn't look so bad once a program is established. It's like aging cheese - get one batch started while another is finishing up. The turnover time is just 50 years instead of 2.
Today’s new motels are often branded as “boutiques” and charge four-star rates to match that kind of exclusive service and local experience.
This is ridiculous... The idea of a "motel" is to be cheap. I'm not too fond of this article. It wasn't well written. Nothing great about it. Some chain hotels purchasing old motels and rebrand them. Whatever.
This is part of an ongoing trend of things from the 80s and 90s being rebranded as upscale for millennials who only have fleeting memories of it or family stories about it.
Millennials now have real jobs and real money now so there's money to be made by turning things from that time period upscale experiences for them to relive with nostalgia.

See TV/Hollywood. :/ Tons and tons of remakes. Some are decent enough (the 2017 Duck Tales was solid), but they're pretty clear cash/attention grabs...
The idea of a motel (“motor hotel”) is to be a convenient to motorists, often as a stopping point or destination on road trips by family vehicle. Now, that market historically has skewed more working class than that for “destination” hotels not focussed on motorists, where guests were assumed to be brought to and from the hotel by a driver—taxi, etc.—for the last/first leg, an by longer range owned or hired transport—air, usually, these days—so, yes, on average motels have been cheaper, but that is incidental rather than central to the idea of a motel.
The stereotypical cheap motel is almost guaranteed to be an unpleasant experience because of the riff-raff it attracts and the extremely low level of service/cleaning. That said, they exist to serve a need, they're not going to go out of business anytime soon.
The "rebanded" hipster motels are quite nice, I stayed at one in Marfa TX and also a different one somewhere in MA. Such motels can only exist if there's enough visitors to make them worthwhile, they also serve a need.
David Spade (Kuzco): It was me and Owen Wilson. We were going to switch jobs. I was an emperor and he was a peasant, and Carla Gugino was a princess. The first time I did my voice, I was naïvely saying, “What do you want? This kind of guy? A deep voice? Or an emperor like, ‘Ooh,’ a highfalutin guy?” And they said, “No, just your nasally, normal, annoying, sarcastic voice.”
I've used a bunch of these tools in the past as part of tools like Wordstream and Opteo. While basic, they seemed to work well enough. What would make me use our service which doesn't have the other ad management tools built into it just to do simple ab testing?
Actually, those are two of the tools we've used in the past and the one we used most recently before starting this project. They work pretty well for a/b testing, but since they have so many other ad account features they need to maintain and update, I think we will be able to offer a better a/b testing platform. Already we can test multiple ad types which the other platforms don't have in place yet. Our ad writer is more advanced also in that you can not only select a previous ad from anywhere in your account as a starting point for a new ad, you can mix and match individual ad elements from elsewhere in your account by selecting ones that have the best performance in other ads.
We hope to get a few more Google Testing options in place, like GDN and RSA (yes, you can test those too), and then expand to Bing, then facebook and twitter ads.
The subject of the antitrust suits filed against Facebook came up in a Facebook comment thread for me yesterday.
Some guy piped up and stated, essentially, that "Zuckerberg is too rich and too big and nothing will happen.". He evidently had never heard of Standard Oil or Ma Bell.
Standard Oil was broken up over 100 years ago and Bell System took 70 years of antitrust complaints (the last case ran through courts for over a decade!) and even then Bell eventually caved and broke themselves up.
Never say never and all that...but it's not like past precedence has shown us the courts are trigger happy when it comes to breaking up monopolies.
