I've been thinking a lot about good programmers lately. I think the only real requirement to become a good programmer is a genuine love of the work (which is no different from any other trade I imagine). If you don't actually love programming you can still achieve a level of proficiency that ...

Questions/Help  - 
 
My printer's been working well for awhile now so I feel like it's time to break it by trying to make it print better ;)

I've noticed that I've got some artifacts that look a lot like the "ringing" described in the post linked below.  I'd like to spend some time tuning the machine to see if I can eliminate this stuff but I'm wondering if there's a more current guide like this and in particular, one that covers the i2 Prusa Mendel and Marlin firmware.

Any recommendations?

So this is interesting, maybe someone more familiar with this hardware can explain?

I have a new Chromebook (Lenovo Thinkpad Yoga 11e) and while digging around inside looking for ways to expand the internal storage I found two banks of four chips that I figured were the RAM (4Gb) and flash/ssd (16Gb).

I Googled the chips and what I found didn't add up to me.  The two sets are made of four chips with matching numbers, however the spec sheets for these numbers are both for Samsung SDRAM?

Maybe it's all part of the RAM and the chips are used in pairs or something like that, but it seemed weird to me.  If so, I'll have to pull the machine apart again to try and locate the flash, because that's what I'm really interested in messing with :)

I'll try and post the photos as well.

Having spent a few days using the Thinkpad for real work I wanted to follow-up on my first impressions review and illustrate the reasons why I think this machine is a keeper. IMG_1097.JPG. First off all of the positive points from my first impressions post hold true. The keyboard is really, ...

Issues and Problems  - 
 
Hey all,

I notice that often when my Chrombook goes to sleep it disconnects the flash storage (USB, SD Card, etc.) and when I wake it up I get the "whoa there!" warning.  This causes problems when I've got chroots running on those devices.

With my old Chromebook this wasn't as bad but with the new one often it won't re-mount these drives without a reboot, which is really a hassle.

Is there a way to tell ChromeOS to not do this? :)  I'm guessing that it's entering some power-saving mode that turns off the interface hardware for these devices but Google is pretty opaque about letting you fiddle with the details of power management so that's just a guess.

Anyone else have this issue and/or a solution?

Having read this through I can see now why this is more of a problem on the new Intel-based machine vs. my old ARM one.  Ideally it would treat the SD card the same as the internal eMMC (I assume eMMC, I haven't taken it apart yet) but I get that there's potentially a USB bus in the middle there.

As you may know a little more than a year ago I traded in my Apple Macbook Air 11 for a $300 (now $200) HP Chromebook. That machine demonstrated (for the lowest possible cash outlay) that I could not only get by, but thrive using an inexpensive Linux-based laptop as my "daily driver".

Just thought I'd share this (since I seem to post most when I'm breaking things :)

My trusty i2 Prusa has been printing so long now that I actually wore out the plywood groove mount. I noticed some weird stuff on my prints and then watched it a bit and notice the hot-end "wiggling", even though the bolts are all tight.

I'm not sure how many hours are on it, but I've had it for about three years, and it's worked at least half that time... :)

I'm tempted to print another i2 just because I know how to make it work for sure, then print something new so I've got a working back-up :)

WristReader: a long-lasting, water-resistant ebook on your wrist; worth pursuing?

http://jjg.preposter.us/wrist-reader-for-pebble.html
WristReader is a Pebble app version of an idea for a minimalist e-reader that came out of some research I had read on how constrained reading devices can make reading easier for people who struggle with reading and a number of e-reader user interface conversations Preston & I have had.

Here's a couple photos of the chips mentioned in my other post, one is from the top of the board (under the keyboard) and the other from the bottom.

Just above his right knuckle appears to be an msata ssd. If you have time can you update on what that is? I really want one of this bad boys but I want to run linux on it and want a bigger HD like you.

+Nicholas Reynolds if the machine holds up until the warranty expires (which it feels like it could) I might give that a go.

I started trying to figure out which chips on the board at the flash but when I started looking up the parts thee numbers didn't add up, so I may need som pointers there.

Any resources you can recommend?
