That Go concurrency is threads is the point of the article. It says this explicitly: "You can think of goroutines as threads, it's a fairly good mental model. They are truly cheap threads". If OS threads become as cheap as us

The problem with Kuhn is that his central thesis of incommensurability as it is commonly interpreted is false. Classical mechanics arises as a specific limit of quantum mechanics. Galilean invariance arises as a specific limit of special re

You can trivially redirect all clients to node 1 whether or not there is a partition, and voila, you have a CAP system under that definition. If clients can be partitioned from servers then we're back in the original scenario in which

Read latency doesn't have to be impacted by linearizibility. Write latency is higher, but we have to do a fair comparison. If a non-consistent database acknowledges a write it doesn't have to have made that write visible, so compa

by jules 8y ago
Consistency in the CAP sense has a precise meaning: all reads see all completed writes. That is, if the database has told some client that their write succeeded, then it is not allowed to still serve other clients the old data. Inconsistenc

It is true: if you allow clients to switch then you can have all three C,A,P.

The CAP theorem has been truly disastrous for databases. The CAP theorem simply says that if you have a database on 2 servers and the connection between those serves goes down, then queries against one server don't see new updates from

Values that have that ratio might be good, but I'm not sure about the magnitude because maybe the average number of votes is too high so that the prior overwhelms the data. The scores get pulled towards that ratio as you increase the m

Have you tried the simple Bayesian approach with a Beta prior? [1] I'd be interested to learn how it does. pretend_upvotes = 4 pretend_downvotes = 4 def score(item_upvotes, item_downvotes): upvotes = item_upvotes + pretend

Julia combines rapid prototyping with a well designed language and good execution speed. Matlab only has the first of those three. Julia can plot eigenvalues no problem. Almost exactly the same code works.

The KL divergence is also called relative entropy. Unlike the ordinary entropy, relative entropy is invariant under parameter transformations. The maximum relative entropy principle generalises Bayesian inference. The distribution relative

I know, you have to flip some other quantities besides velocities, but I didn't want to make it more complicated.

It gets even weirder. The laws of physics are time reversible as far as we know. Very basically, it means that if you froze our universe and reversed all the velocities of the elementary particles, and then restarted the simulation again, i

You're completely right that there is nothing revolutionary about viewing a point in spacetime as a point (x,y,z,t) in 4 dimensions. If that was what special relativity was about then it would be very boring! The x,y,z directions are c

This is the same argument that gets brought up for every language feature. I remember the days when lambdas were controversial. Lambdas used to be seen as crazy complicated magic that normal programmers wouldn't be able to understand,

This is the opposite of the monorepo philosophy: everyone always uses the most recent version of the code to minimise hassle. I wonder if minimal version selection works nicely initially, but becomes more of a hassle over time because you&#

That's right. For a fully connected layer the matrix is of dimension (batch size) x (number of neurons in layer k) which gets multiplied by a matrix of dimension (number of neurons in layer k) x (number of neurons in layer k+1). People

by jules 8y ago
Fully connected layers are matrix-vector multiplication (which turns into matrix-matrix if you do an entire batch at once). Convolutional layers are lots of tiny dot products. You can rewrite that as matrix-matrix multiplication.

The algorithms with the best asymptotic complexity aren't used in practice because they are slow for the n we care about. In practice optimising matrix multiplication comes down to making efficient use of SIMD, multiple cores and cache

Copy on write handles most cases fine. You can also still use such a system as a repl: just add more lines and don't modify previous lines. If you do that then nothing needs to be re-executed. Since most people work with small data set

What if notebooks re-executed all cells in order as you type? That would solve the ordering and hidden state problem. To speed that up you could take a snapshot of the program state at each cell and re-execute from the snapshot of the cell

That it would hurt vulnerable populations who live in a region that becomes uninhabitable is undoubtedly true and I didn't argue against that, but that is not the end of humanity, which is what you claimed.
