Full disclosure: former iRobot engineer speaking - Coincidentally, for the latest Roomba (the 980), we did have a camera on the robot which did visual SLAM for precisely that purpose...the idea being it would map your house while it went, a

Thanks for the info! My experience in the past was mainly with large LN2 dewars, with liquid helium refrigerators added to re-condense the N2 gas back to a liquid, limiting the pressure (and limiting how often you needed and LN2 refill!). W

I can't think of the manufacturer of the top of my head, but there are definitely off-the-shelf options. They are used on the LN2 tanks and dewars you see at a lot of electronics (and I'm sure other) manufacturers, and I'm pr

From what I can see, the course you mentioned looks very cool, however it seems a lot of the slides and linked papers are password protected. Do you have copies mirrored and/or know if the professor would be OK with these being shared?

Haha, I was just about to reply to your comment with nearly the same thing! I think one day I may need to do a book on C++ for embedded folks. Chapter 1 will be "Please don't use std::string!".

No No No! Don't apologize, its a great question! And to be fair I'm absolutely against "cargo cult" programming, and my point was actually that when you are doing C++ in this type of environment, you can't always st

I'm pretty sure it is! ( I'm also pretty sure that for a subset of the HN crowd, you may have just proven Linus's point :-P )

As other's have stated, that is just Linus's opinion, which he is entitled to. It's also even understandable given his position managing all of the Linux kernel and git development work, and the large number of people who con

Out of curiosity, I'm wondering why you say: "Charitable organizations don't give homeless people privacy for fear of the human things they will do, like drink, use drugs, have sex, etc."? I know very little about how mo

Out of curiosity, have you heard of project cybersyn? https://en.m.wikipedia.org/wiki/Project_Cybersyn

The original story mentioned drinking 5-hour energy drinks, or their generic equivalent. Take a look at the nutrition label. 2000% B6 and over 8000% B12! http://www.energytin.com/blog/wp-content/uploads/2011&#

Fair enough, and I'm not defending the "it will kill you" line, I was just pointing out that they were likely referring to DI water, not distilled as mentioned in the comment, since others may not have heard of / known t

by TFortunato 10y ago
FWIW, they aren't talking about distilled water, they are talking about DI water (deionized), which is different and more reactive / corrosive. Yeah, a sip isn't going kill you, but I wouldn't make a habit of it either.

Very cool! Money came mainly from sales, but we also offered training courses and had a large services and maintenance division, since the tools did require periodic maintenance. A lot of these tools also have "consumables", just

This is true. The wafer carrying "foups" mentioned are actually an acronym for Front Opening Unified Pods, which is what carry the wafers from machine to machine in batches of up to 25 wafers at a time. They are typically UV opaqu

In many cases, sure, however there are definitely cases where microcontrollers still make sense, i.e. real-time control, low power applications. I work in embedded systems, and a lot of the reason you would choose a microcontroller is all o
