Ask HN: How difficult is it to shift a database?
We are planning to move from Neo4j in the future to a more cheaper option like OrientDb or IBMGraph. Can some one help us to know how difficult this process is going to be.
But processing does increase the "obviousness" of the information content.

E.g. projecting the data onto independent dimensions doesn't change the information it contains, but it highlights that those dimensions are indeed independent. Decomposing a multimodal distribution into a mixture of unimodal distribution gives more insight than just viewing it as a bunch of data mushed together. And so on.

I think there should be a branch of information theory that quantifies the obviousness of information and how it is changed by various data processing methods.

Richard Serra's most controversial piece, Tilted Arc, was removed after 8 years from a plaza in front of a building in Manhattan because "those who worked in the area found the sculpture extremely disruptive to their daily routines, and within months the work had driven over 1300 bureaucratic employees in the greater metro area to sign a petition for its removal."

"Serra states that the case exemplifies the U.S. legal systems preference towards capitalistic property rights over democratic freedom of expression."

There's a paper about this, a bit old at this point, covers the toxic effect you describe:

It doesn't matter how many algorithms or sensors are consulted or combined to form judgment. If an attacker can obtain a self driving vehicle's hardware, and if enough tests can be performed per seconds, the attacker can train images that fool it.

Your idea is similar to an appeal to security through obscurity. Might work sometimes, but not generally.

(Noise does not help, because you can still discover a gradient to descend by averaging repeated trials.)
Label switching is a pretty old concept. We had it at Inmos around 1990 and it wasn't new then.
I think the grandfather post is mainly saying that not thinking this through a lense of risk and reward, that can end up giving kids some good outcome is an error (and for sure having a happy father IS better than a depressive one, so if the cave diving risk is sufficiently low, then it makes sense to do it). This line of thought is also probably similar to what that guy thought (to think it is worth the risk to live like that). In that case, you have a slope of risk that starts reasonably and ends up unacceptable, but where you can't easily pinpoint where to draw the line.

Whether you "buy" the simple causal graph that he used as an example is a minor point.

Those might be reliable but you could achieve the same reliability on commodity hardware for a lower price if you write distributed software and plan for failure.

My SIP server software (for a startup I hope to launch soon) can have its power cable pulled and nobody will realise because the server besides it just took the process over. For the price of a single mainframe I can put hundreds of servers all around the world and still come out cheaper.

Oh, nice. The author presented the subject here in Brazil in 2004. If anyone reading this is from South America, FISL is a great event with great talks (though most of them in Portuguese). The organization is having some financial trouble for this year's edition, but hopefully they'll overcome it.
The current compiler was written with the aim of quick development till 1.0 is reached (because in the initial development phase, there are obviously many other important things to focus on). So, yeah the toolchain has some issues, eg. there are very few (if any) optimizations. Also, only 32 bit is supported.

There are AFAIK no plans to add 64 bit support before bootstrapping phase because the current toolchain architecture isn't that great and will be heavily improved during 1.x cycle.

If some of these projects go on to produce open source software of worth it won't all be for nothing.

Associating the ERC-20 protocol with the current mania and nonsense of cryptocurrencies doesn't seem fair. It's simply a method of creating a sub-currency, which yes is often unnecessary but marketing is a powerful force so it happens.

Having seen small rural communities try and fail to create their own local currency years ago it's only a matter of time before some try again digitally.

Years ago I made a "real time web based traffic map" for a USDOT/MODOT project. We used traffic sensors made by 3M that sent data to a local 911 center that was also setup under the same project.

The sensors sent traffic counts every few minutes and I used that data to draw greeen/yellow/red lines of the areas covered on a road map.

> The same thing (but reverse) with asking children whose fathers didn't go on an adventure and see if they would've preferred a more adventurous father!

Yes, each child only knows one half of the story, as it were. But the knowledge imbalance is not symmetrical. The child whose father has died understands boredom and dissatisfaction in other ways... perhaps his mother is boring, or sometimes nags him, and even his adventurous (now dead) father surely disappointed him sometimes, and so on.

The child who has not experienced death really has no idea what that suffering is like. It's just utterly callow to think his opinion has equal weight.
To me "eating clean" means eating mostly vegetables by volume and mostly fat and protein by weight. For instance typical ketogenic/paleo diet. Eating "dirty" is theoretically doable. If one prototypical example of eating "dirty" is having a standard supermarket cake slice or mound of cereal and milk to fulfill daily caloric needs, then it is actually harder to maintain a "dirty" diet. Satiety becomes an unattainable goal. We simply cannot handle the insulin spikes well. We get hungry and cravings are more intense with such a diet. It is essentially impractical. It may also explain why there are so many obese in the world. "Eating clean" can be used as a marketing term to get people to fork over huge bucks for an oversold concept. But fundamentally, "eating clean" the way I define it is very cheap, tasty, and pragmatic. Especially for losing weight and maintaining a low weight.

> Flownet was a long way from "orders of magnitude" (factors of 10) better.

That article was written towards the end of FlowNet, when we were already winding it down. The work started in 1990. We built our first (and only) prototypes in 1992 (self-funded). Fast Ethernet was not introduced until 1995, and at that point our BOM cost was 20 times lower because our NICs used 100% off-the-shelf commodity hardware, and we didn't need hubs or switches. So for about a year we were 5x faster and 20x cheaper. It took five years for Fast Ethernet to completely catch up with us.

"Decency" is not something that exists in the telco world - the industry is based on shady practices but nobody wants to change that as it would put a lot of middlemen out of business.

In a world where you can watch a 1GB Youtube video in Europe that's hosted in the US at pretty much no charge, do you think it's decent to charge for texts - something that's only 160 bytes of data? Yet that's exactly what the telcos are doing.
OK, thanks. Too late to edit. Adjust flames accordingly. Of course a perceptron is not an accurate model of a biological neuron. But as a reduction to a minimal model it's still pretty darn interesting.
If they're the majority, is it fair to say "they" are insular? It likely goes both ways with the locals not thinking the Chinese students are cool or fun enough, or not bothering to make friends with them because it's just easier to keep doing what they've been doing all their lives.
just some side question...if a non-profit organization "loves your money" (which I would interpret as motivated by your money [at least partially]), would that make it not so much a non-profit organization? If that is the case, would this kind of "love your money" behavior exhibited by a non-profit organization make that organization less trustworthy to you?

Or perhaps we could further refine that "love for money" as "beyond necessity" and "within necessity"...but the problem is very difficult for an external observer to tell where the boundary lies for a particular entity -- although that boundary does exist in many cases...

A registry wouldn't do any good unless each call is backed by cryptographic proof that you own the caller ID, and every telco provider verifying this proof and rejecting any call that has fake/invalid CID.
Yes, absolutely. Red has a `parse` function, that uses EBNF-like rules, but someone has written a nice regex translator if you need that bit. It's also possible to write a nice AWK-like dialect that handles things at a higher level. I've done that in the past. One of the current limitations is that the I/O model is simple, and there is no GC yet. Those will come in the relatively near future, but if you have large files, or need long running processes, it will be more work for a while. Still doable, just not as easy.

The problem with this approach is that you would really have to offer something groundbreaking to displace C and C++ while also matching portability (only matched by Java variants) and performance (often unmatched).

The about only languages that could compete right now are extended Ada for high assurance environments and Fortran variants for HPC. They are old but not dead and quite usable if you have the dollars to buy proprietary or invest time.

Microcontrollers and constrained environments are another critical niche for C and C++, especially given proprietary compilers.

Rust does not go far enough in safety to displace Ada (or Spark variant) while not offering improved performance and comparable portability with all the pains of a new language. It also does not do build once deploy everywhere stuff Java and JS attempt. Rust is neither here nor there.

Well my SIP client app manages the loss of Wi-Fi or mobile connectivity pretty well - I loose audio for a second while it renegotiates the path through the other network link but after that it's business as usual. On a conventional call when I loose cell coverage the call is dropped, so SIP is a winner for me.

On the server side you can do amazing things with high availability like floating/virtual IPs (the IP of the SIP server is actually shared between multiple machines, and if the primary machine goes down the secondary takes over its IP and as far as the client is concerned nothing happened).

Non-GMO and organic is mostly BS of course, but it's a fact that refined carbs are cheap and plentiful, so the poor consume proportionally more of them. They simply can't afford fruit and meat. This is in part because of the infinite shelf life of processed carbs, and in part because they're heavily subsidized by the government. Also, government dietary guidelines still push people towards relatively high carb diets, and snacking is encouraged from kindergarten and up, causing insulin resistance and type 2 diabetes. The point being, the nutritional situation in the US is a clusterfuck, and GMO and organic stuff are kind of orthogonal to rectifying it.

There are factors in games that mean something 'real' probably wouldn't result in a great map. Foremost is the fact the real world doesn't care whether or not there are places where a person can get stuck. A game world has be be designed in a way that means the player can't get stuck in places they can go to, and can't go in to places where they could get stuck. Depending on the game type, the map also often acts as a 'corridor' forcing the player to move through a series of locations in order. Features like that move a game map away from something real really fast.

But at what point do you have to wonder if we're using the wrong basis? And how do you know that augmenting the data with tiny adversarial perturbations won't just leave the network vulnerable in a different direction?

It's pretty obvious how to build translational symmetry into a net that's still expressive and easy to train (convolution). But you have to spoon feed CNNs rotational and other symmetries by augmenting the training data. What you really want is a model that has all the symmetries your data has built in.

My sense is that the community at large seems to regard DL as a magic blackbox which it really is not. Complete basis of function + finite data = guarantee of wonky interpolation between samples. What you really need to do is restrict the class of expressible functions to those you need - build your prior into the model.
Can you describe the ways you have attempted, and the bad outcome, to help focus the answer/search a little more?

Java Achilles foot has always been memory use and really compute constrained environments. Things like high end video game engines are not being written in Java, Closure or Scala for these very reason.

I would be very careful about JIT performance being even close. See, the language does not even expose SIMD well. Doing anything hard realtime (heck, even more complex UI) with a JVM in the way is a big pain.
