Alibaba has developed another DB called OceanBase (open source).

AFAIK, you can't buy new 6502s any more (nor can you buy the 6510 actually used in the C64). You can buy 65c02 chips, but those are slightly incompatible with the 6502 and 6510 on the opcode level.
This is one cool hack.

You can't construct deep neural network from only linear parts because consecutive layers can be always combined into single transformation matrix. That's why you need alternating linear and nonlinear operations.

I wonder if it's possible to design special purpose low resolution floating point circuit that maximizes this effect while preserving enough linearity. Then you have fast DNN network pipeline constructed from just summation and addition.

Good job, fantastic. Don't let the parent complainer get you down, you really nailed it. There's a reason everyone uses React and you're a large part of that reason. Kudos.
I think it's just general cynicism. Most people, despite us being in the startup space, tend to put down or dismiss those with huge ambitions.
It still seems rather ambitious to me. 2022 is coming up pretty quick. If I were a betting man I'd bet they will push back to 2025-2027.
That's an absolutely beautiful website by a framework I hope to never use again.

React feels so much nicer and it's use of Vanilla JS makes it so much easier to debug. It's a breath of fresh air.
You're right. Fixed.

(I habitually type it "Javascript" but it is indeed supposed to be "JavaScript".)
Honestly, we have to bend everything out of shape to make any functional software for any domain, using any technology. It is just natural that people have problems identifying wether stuff suits their problem or not.

Our project management app - paymoapp.com is built on Sencha and we're a bit worried. We spent a lot of resources building ext6 apps on top of the old ext4 core - hopeful Idera won't do crazy stuff, it's a good framework worth saving.

> Really, it's the news agencies which are the worst offenders in this regard, which is doubly bad because they will actually sacrifice clarity and accuracy to avoid these words.

News agencies do not sell clarity and accuracy, they sell advertising views. Enough of the suppliers of advertising views will stop supplying that good for news agencies to sell if they encounter a “fuck”, even in a context where it wouldn't earn an FCC fine, that news agencies have a clear economic incentive to avoid the word.

Mars is way closer.

Mars has a more terrestrially-similar gravity level.

Mars has way more solar power.

Ceres is basically vacuum, can't aerobrake. And its gravity well is so small you also can't take advantage of the Oberth effect.

Mars' atmosphere shields you from the vast majority of solar radiation (so no risk of death from acute radiation poisoning), from all micrometeorites, and even a significant amount of galactic cosmic radiation. It also provides global access to gaseous CO2, nitrogen, argon, and even some water vapor.

Mars can be terraformed.
Thanks. I did read all of this and I'm pretty sure I get most of it. :)
I found terminal sounds, fricatives and sibilants to be at a mininal distracting with RNN for "car" and "street", and at worst unintelligable. In particular, the terminal sound in "Christmas" was completely lost in the noise for me at 10dB with RNN, but was perfectly fine in Speex.

For "car" RNN sounded as good or better than Speex at all noise levels.

That rnn_hack is significantly better for me. 5dB on that sounds strictly better than 10dB on the original to my ear for "babble" and "street". I also noticed that the for the parts that sound the worst to me at 10-15dB in the original RNN, the signal is completely missing in the 0dB RNN version, so perhaps the signal is in the same band as the noise at that part?

Either way it's a tough tradeoff because I suspect that low bitrate encodings will love the nearly empty signal in the bands that are generated by the original, but the seemingly rectangular cutoff/introduction of the noise was much more jarring to me than the reverberation added by Speex (though I didn't like that in Speex, it didn't seem to add to my effort to understand the way that.
You answered your own question: military applications.

The US Armed Forces would pay a LOT of money to move 100+ tons of personnel and materiel anywhere on earth with a flat landing spot in under 60 minutes.

You could have tanks on the ground that were fully operational in under 3 hours (probably half that if they left the BFR packed and fueled for takeoff at all times), or a disaster recovery base set up within 24 hours of the winds dying down (to pick a more topical example.)

Let's imagine a more extreme example to make the point clearer. Imagine you have to become a live-in carer for an elderly relative, and they rely on you to take care of their every need, with very little in the way of time off. Can you see that such a situation, whilst still something that can be carried with dutifully with a minimum of fuss, could still be emotionally draining for someone? If so, what do you think causes the situation to be emotionally draining?

Hi-

I worked on this along with some other people.

Here's what a demo looks like:

You can try a really cool demo made with it here:

It fills your room with water and has ducks swimming around. The sound changes if you dive underwater, and if you press the screen, the ducks will swim towards you. This is a video of what it looks like:

How? Is there a simple solution that would work in the U.S. as well? Most people I've heard that are reasonably informed about it here invariably end up with, "It's complicated, because it's a combination of issues spanning mental health, law enforcement, drug policy, etc..."
I can't come up with a scenario where the BFR ship would make an emergency water landing. (Of course, it could just be that I lack knowledge or imagination.) Airliners can do them because they glide, so water landings are a possibility after fuel exhaustion or engine failure. BFR won't glide well enough to land softly, so it would have to be a propulsive water landing. And if you can land propulsively in the water, surely you can land propulsively at the landing pad.
"Car culture" generally brings out the same primate programming you see in the "comments section". There's a level of pseudo-anonymity that brings out the aggressive asshole in all of us and make it unsafe for the most vulnerable.

Its night and day when you are on a bicycle versus a car. I get conversations and interactions with people while biking that makes the experience so much more "human" (for lack of a better word).

The one that you understand and have skills, knowledge, abilities, or relationships that you can apply.

I know that's kind of cliche but there are opportunities and/or places to help all over the place. It's a matter of finding the ones that you can a) get passionate about and b) be successful at. And this applies to startups, non-profits, or even that internal project.

Personally, I work to support Austin Disaster Relief Network - https://adrn.org/ - which is a group of ~150 churches in Central Texas that come together to help people during flood, fire, hurricane, and anything else. We are background checked and badged to cross the emergency tape and help the Red Cross, local PD, or whoever else is on the scene. The focus first is helping people immediately.. while their house is still on fire. And then help them get back on their feet.

While I have first aid training, my specific role is helping on the technology side. When something happens - like Hurricane Harvey - we can stand up a 25 person call center in under an hour. It's powered by Cisco phones plugged into a local Asterisk/FreePBX server connected to Twilio. (I'm a former Twilio employee but they're not involved.) In the field, ADRN uses simple web and mobile apps to collect victim info and issue gift cards. It's tied into geolocation services and person databases to reduce fraud. There are online/offline modes for when you're in the field where there is no connectivity. There are a ton of technical roles required!

And the underlying aspect of all of this is that we design, build, and deploy technology with the HOPE that it never gets used. If it's used, that means something horrible happened.

And btw, Harvey isn't over for people in the field. All help is appreciated - https://adrn.org/disaster-relief/hurricaneharvey/
It wasn't merely an accident. The US had a superior context which enabled something like IBM to exist and thrive.

Name another country circa 1911 that could have produced IBM and enabled it to acquire such vast global scale at its peak. There are only a handful of nations that can even be considered as possible.

IBM came out of the US for the exact same reason Fairchild, Intel, Cisco, Silicon Graphics, Motorola, Texas Instruments, HP, Sun, Xerox, AMD, Apple, Qualcomm, etc. all did.

Well, the mountaineer reason of ”because it’s there”, which honestly is probably the more honest and moral of the two. To become a ”mulit-planet species” in a real sense we need more earthlike planets, else the iss in orbit around the moon would be enought to make the claim. Consider that we don’t cout ourselves as an underwater species just by virtue of submarines. Even if we made a self sustaining underwater base and condemneded people to live there forever it would just be those poor people living underwater, we aren’t suddenly a underwater species.
I see two things:

1) making data and facts more available and easier usable for everyone. This includes good sources, polished data streams and - the most neglected thing I suppose - good UI for non-techs.

2) Decentralize applications, plug in interoperability. OStatus is a good example of this. We need to reduce datasilo hoarding monopolies. This also partly plays into 1)

There are probably huge strides that can be taken in healthcare, food, energy, transportation and finances. The challenge is that most of these industries are heavily regulated so you go in optimistic then get inundated with endless waves of bureaucracy, and end up making a new version of Twitter.

Why?

We know for a fact that GC'ed langauges can e.g. prevent double-free for ever and ever. Obviously, this is modulo the language/runtime implementation, but if there are bugs there you fix them once and every single program out there gets the fix instantly.

Similarly for many other types of 'dangerous' bugs.
Then either the readme in the proposal is wrong or the unknown babel preset is wrong

Assuming the relocation of work is only due to arbitrage in wages and not bypassing environmental or human rights causes, then how is it decided what can be arbitraged, and who gets to decide this?

Are people allowed to go to Walmart and choose to buy something for less money than the mom and pop store? Are traders allowed to take advantage of pricing differentials in different markets? Are employers allowed to relocated outside of San Francisco to find less expensive employees?

You can try to stop the market from reaching equilibrium...but I have a feeling you won't win in the end, at least not without some help from the armed forces.
Systematic if it's in a controlled and repeatable environment. Not so systematic if you need a robot to assemble your table in the middle of your living room. You can't achieve Ikea's scale by completely assembling everything in a factory because it increases shipping, storage and logistic costs-- not to mention complicating moving the furniture into your new home.
"Too big" isn't a thing. "Too expensive per flight" is.

In aircraft, cost per flight is roughly proportional to aircraft size, so "too big" can be indirectly a problem.

With rockets, the difference between fully/rapidly reusable and expendable (or even partially reusable) is so vast that "too big" is basically irrelevant.

In his presentation, Musk showed the expected per-flight costs. BFR would be cheaper /per flight/ than Falcon1. ...and if you dig into last year's presentation, the projected per-flight costs are lower even than Rocketlab's Electron. PER FLIGHT.
> in the end the government of the PRC has the capability to coerce the company to exert influence in a direction we almost certainly wouldn't like.

It's open source- when that happens, you can fork it and influence it in the direction that you like. I mean if the GCHQ has an active github account[1] - I think the PRC gets a pass to publish open source, let alone Alibaba.

This trope is doubly lame on Hacker News: both a personal swipe and a heat-dead cliché. Please don't comment like this here.

A couple points:

First off, in the 'backup' argument Mars isn't meant as a bomb shelter for the human species. It's a shelter for human civilization, which is a higher level and much more fragile thing. Think about the libraries of the Arab world, not "The Arabs have to exist or humanity could die out when Rome falls!"

The other argument is as a launchpad. Mars is halfway to anywhere in the same way low earth orbit is, but Mars comes with exploitable resources. In the future, we can debate whether those resources are better exploited by enormous robotic fleets and autonomous systems or with humans on site, but with current tech readiness levels nothing beats in-situ humans for adaptability. A strong Martian industrial base will produce huge returns for terrestrial society. From dense high-throughput communication networks to massive orbital manufacturing depots to idyllic ring-world habitats, everything we want to put in orbit is cheaper starting from Mars.

They're only just proving this out, but one of the theses behind Made in Space [0] is that there are all sorts of microscopic manufacturing processes - optical components and chips being the most obvious - which would benefit from manufacturing in an ambient gravity between 0-1g. Which you simply can't get on Earth.

I live in Sweden, and major power outages are rare here too (latest was in 2003 and 1983). Small ones happens from time to time. I was convinced that it was a legal requirement here too, but it turns out that's not the case. Fortunately that will be changed, so from 2020 it will be mandatory here.

But, even if it is a legal requirement, it will not always work. All that is needed is a major storm that disrupts the normal power, and it will be down for days or maybe even months...
> Then they upgraded ExtJS (can't remember if it was to Ext5 or 4.x) and deleted all the comments as 'no longer relevant'.

Oh, wow.

My observation is that treating documentation thoughtlessly is frequently a leading indicator that "treating their community like shit" is coming soon.

Product folks and developer evangelists: never do this. Never do the thing where you simply blow away a community-grown resource. If you're absolutely sure you're in a situation that's the exception, you are probably still wrong. Wait a year or two after you're sure. Then warn people and give them a year to save whatever they think is valuable.

Any other approach is telegraphing either thoughtlessness or contempt, possibly both.

Ask HN: Workflow selected by the Thiel Fellowship (2014). Is this usual?
I love Workflow and the domain of personal productivity software in general. However it's not a domain known for attracting VC (and similar) interest because it's not consumer viral or enterprise scale. For this reason, something like the Thiel Fellowship choosing Workflow seemed delightfully odd to me. Is this usual? Can anyone think of similar examples of angels/VCs/incubators/etc. going in on personal utility apps? Or was this just a one off and/or some clever business people predicted the Apple acquisition?
Look into the concept of "common intent" that I linked. It gives you all the same things obedience does, but for much more sensible, egalitarian reasons.

(And the military itself knows this; scroll further down on the same page to read about "Command intent"—which is sort of, 1. the planned incentivization that commanders and law-makers do, giving orders that will be misinterpreted and misapplied by people with conflicting preferences to give results they ultimately want, rather than giving orders that are "right" at first but which go wrong after a fifteen-layer game of hierarchical telephone; and 2. the knowledge that the orders you've been given are of this "robust under misinterpretation" type, and so knowing to not read too much about the original "Commander's intent" into them.)

Teaching a child that following orders is good, but that disobeying "bad" orders is also good, is virtue ethics, and has all the same problems as virtue ethics: there's no clear test for which virtue wins when two virtues come into conflict.

Common intent sets a much clearer standard: just understand the intent of the person giving the order—the "spirit of the law"—and then obey that, disobeying the letter of the law if-and-only-if it conflicts with the spirit of the law. This shakes out to obedience to good orders (or orders given by trusted commanders) but disobedience to bad orders (or orders given by untrusted commanders) ...except where a good law/trusted commander applies a meta-order to the effect of "please do me the favor of following the bad orders; it advances the spirit of the law in a hard-to-follow consequentialist way that you'll be able to see in retrospect."

Which is pretty much what humans who we consider to have "character" already do intuitively, so it's (hopefully) a good thing to systematize.
I worked at a company for 4 years that used Ext for everything. I got to know the framework really well. Everything you say is true, but I honestly don't miss it. I like that React (I've never used Vue), leaves this open to your choice.

Sencha really wanted their customers to lock into Ext and not be able to leave. I like that modern solutions are about choice and flexibility.
Interesting. Thanks for your reply.

The point is with a rocket, if you can't land at your original destination, you probably don't have the capability to safely land anywhere else. Maybe I'm overlooking a scenario you have in mind, but IMO you're looking at two classes of problems:

1) Problem during launch. There's been one successful use of a launch escape system in rocketry history[1], and such a system has never been developed for a shuttle type craft.

2) Problem after entering orbit. Cutting your orbital flight short isn't going to change the fact that you still have to survive re-entry stresses and have a working vertical landing system.
