That's a cat-and-mouse game, and the Firefox release cycle is bound to be much slower than any website interested in tracking users. The owners of the site can tweak the JS slightly, the FF devs have to get notified that the website st

Amazing achievement. It's great that they released the telemetry data as well.

I wouldn't say that's a big concern. Because you control the binaries that run on AWS Lambda, it wouldn't be too hard to move the event-based logic of invoking a function to your own custom task queue. Other AWS services are

Interesting idea. I think the biggest challenge would be to filter out noise (i.e wind blowing on the microphone). But in a limited domain such as this you can do aggressive filtering and get fairly good results in very harsh environments.

The electronic speed controllers we use in RC have a loop time of a few milliseconds and are fully programmable. Some of them are capable of sensing the current going into the motor. You can also monitor the voltage instead of/in addit

From the name I thought it was going to be a book of text generated by a Markov chain trained on HN comment data. Took me a while to figure out it wasn't. Anyway, good collection of comments. It'd be useful to have a HTML version

One way of doing this (for your particular use case, but not for the general case) would be for your "business logic" to be implemented in the client side, which as you said, can be verified easily. Then make your backend be a dum

I'd think tomjen3 meant "Yeah Theo made a fork of (...)" instead of "Yeah Theo they". Looks like he originally wrote "Yeah they made a fork (...)", then he rephrased and forgot to delete the "they&quo

The ideas behind this article are good. The author gives some guidelines that have helped them write better software. However, it makes me think about how we can make "making software" better. It seems like the best current way of

This is pretty cool, and I'm glad circuit manufacturing technology is making its way to the home. It still has a long way to go - a pick-and-place attachment would be very neat - but it's a promising step in the right direction. H

I don't have a citation on hand unfortunately but I do remember he said he'd want to "die on Mars... just not on impact."

The only part where I suggested to store a monad in a file is when I proposed it as a way of pausing a computation and resuming its execution at a later point in time. My mistake for mentioning the word "file", but I meant it in t

But that's an optimisation. Which can be switched off to get the benefits from parallelism. This is a tradeoff that programmers would traditionally have to consider, but with functional programming the compiler can figure it out for us
436.
by jdiez17 12y ago
You can use the Either monad to figure out where the computation failed and give meaningful errors. Or the Writer monad, to add logging to the computation. Being able to resume the computation is possible, due to referential transparency -

Yeah, but gus_massa calculated the upper bound of the sunlight->electric current conversion using the material we were talking about, which seems like an improvement to me. However I don't know what the ballpark efficiency of solar

by jdiez17 12y ago
From a quick search, most solar panels I can find are 15-20% efficient, so (from a quick look) this seems like a noticeable improvement, no?

Thanks for sharing this. I've been interested in Haskell for a while and I hadn't really started writing any actual programs until very recently[1]. I also wanted to learn about neural networks, and reading your source code was qu

Okay, Terminus looks pretty good. I wish rxvt could do this, too. Thanks for those links.

This is a feature I'd actually really like to have in an actual terminal. The ability to display graphics would be useful for many things.

A good type system does not prevent you from making logic errors. It's just another level of protection, like managed memory. In the same way that reference counting prevents you from leaking memory, a type system prevents certain kind

In my experience (OP's post resonates highly with me, I've also been dabbling in Haskell for a while and consider myself somewhat competent), it's a long term investment. I've been at it on and off for a while and even t

This is very interesting, thanks for sharing it. I've been looking at home automation solutions and I want to make my own - I want to be able to control every switch and socket in my house, so I'd need very inexpensive nodes. I wa

Looks like the only code they've published is here: https://svn.apache.org/repos/asf/incubator/nifi/ So it's only the site code for now. We'll have to wait, then. NiFi looks interesting...

There are a few things you should now: first, the actual physical memory of your computer is pretty much like a big array: if you were writing code in assembly and were to run it with no operating system, that's exactly what you'd

I have been learning a bit of Haskell on the side recently just for the thrill of learning something completely different to the way I'm used to writing code. My two cents so far is that using Haskell for "Real World" applica

As a 3D printing enthusiast (I've built two 3D printers of my own), the scale of this blows me away. Stereolithography is an amazing technology. It uses light to solidify a liquid resin.
