My understanding is there are a number of things that have to be right. In addition to rigidity and precision of the machine itself (bushing quality, rod runout), the speed, layer height, temperature, and filament regularity are all import

I recently read up quite a bit on FDM robots, and in my opinion it would be a shame to pass up the opportunity to build a robot yourself, and even design one yourself. The cartesian machines are more or less variations on a theme, and most

If the scandals described in this article and Taibi's articles are the result of a few bad actors, and if the result of these scandals is a broad perception on the part of the public that the entire financial sector is corrupt, then Go

I think a large part of making better coffee is a matter of iteration, or trial and error. If you do something and it tastes better, you keep doing it. But you're never sure if there's some patch of the search space that you mis

I agree. Apple has used the geometry of the device to assist more with cooling, and shares the heat sink among components, and uses one large slow fan. This kind of thing really pushes my buttons. It's 10" high, which is unexpec

twbrownaw is exactly right. If the private key is already in a secure location then there is no need to move it to a secure location. So, any report that the public keys were stored with the private keys means nothing by itself.

Without being surprised I'm a little curious about the statement that the game required access to the server, in order to run. I'm curious how statements like that get made, because it seems like it's just a matter of time before the truth

Part of the reason it comes up frequently is that a large number of educated, experienced programmers have decided that a toolbox without OOP is a better toolbox, than a toolbox with OOP. But, it is difficult to throw out a bad tool when th

It is straightforward to convert stack instructions to 3-address instructions, by keeping a counter -- a stack pointer -- that points into the register file. As instructions are decoded the stack pointer is read and the current reading is

It's great to see people using Chuck's work, and in particular it's wonderful to see your reaction. I think it would be easy to recoil at the strange tools, not to mention the difficulty of programming the thing. I agree it's a fascinatin

Are you able to boot all the cores and get them functional? I like the design of these chips too, especially how each core "blocks" on its message queue by instantly going to sleep, taking zero power -- and then instantly wakes up the mome

It would have been better if I had specified absolute values in the formula. I hope the point came through. (It appears I'm unable to edit this particular comment.)

If we're on embedded hardware, or can't use floats for some reason, we use 22/7. It's called fixed point arithmetic. Most CPUs have an integer instruction that multiplies into a double-precision integer result, and an instruction that tak

Yes, Jon's metric for measuring the value of an approximation is wrong and so is his conclusion.

Yes that was my mistake. Sorry about that. It must happen because of the byline above the box where one types in the top-level comment. Thanks for mentioning that it's a frequent error, that makes me feel better.

22/7 is a better approximation of pi than 3.14 because 22/7 is closer to pi than 3.14. The hypothesis of the article is wrong. I believe Colin [EDIT: I meant Jon McLoone, the author of the article. Sorry Colin!] is counting only full digi

(pi - 22/7) < (pi - 3.14). 22/7 is closer to pi than 3.14.

This article introduces concatenative langauges, but it doesn't explain why they matter. In my work, I found that the lack of syntactic marking for arguments of function calls is a devastating drawback. Coming back to my own function defin

What's happened here is that Sony has discovered a previously undetected attack that occurred in April. So this second attack is not as new as one might think.

Game consoles have been successful so far with closed systems, and they've learned over the years how to improve their security, a key one being forced firmware updates.

I don't know how WoW phrases it, but the promise "buy a subscription and get one month free" is not the same in the mind of the customer as the promise "free one-month trial". The first gives a more accurate description of what will happen

In 2002, Yahoo! began a serious effort to compete with Google in search by buying Inktomi (plus Altavista and FAST). In what must have been early 2004, I came over with the rest of the Inktomi crew to work on search. The Inktomi people we

When you say "they would dig into their network" do you mean that first, the VCs recommend that you hire the executive, and then the executive hires his impressive contact -- the one who is supposed to make magic? What do you suppose is goi

"Bring[ing] everyone else to your pace" by increasing latency struck me as a really nice idea. It suggests an additional feature that could be added to a site like Hacker News, where each reader can choose an update interval, and have news

Allowing a tyrant to exert his will may result in less freedom for others. Judging by the technical way you couched your argument, I think you're aware of the subtle way freedom works. It wasn't difficult for me to get what Steve was talk
