cycomachead··on Sitting down at work is no worse for you than standing up, study claims
I don't think it necessarily needs dismissing... It's basically saying sitting isn't so bad as long as you exercise and take breaks and move. Which...yeah...duh...?

This one of the things activity tracking devices are good at. The Apple watch has a "stand" metric, but what it's really trying to measure is if you get to N level of movement during each hour. Standing in place won't cut it. I've only ever tried the watch, but other trackers like the Jawbone, I believe should do the same thing.

The thing is, properly used sit-stand desks give people much more freedom to change their position as desired. I recently got a sit-stand desk, and it is easier to move around if I'm already standing. It's only been a couple weeks, so we'll see.

cycomachead··on Blowing the Whistle on the UC Berkeley Mathematics Department
UC Berkeley does accept earmarked donations, but there is a limit to how specific they can be. I'm not sure what that particular level is, to be clear, but I've heard it's above the "it must go to this lab / group / person" level.

Scott Shenker, a CS Prof actually has an unrelated campaign right now where he'll match his student donations 10:1, so a few friends and I have been discussing some rules lately.

cycomachead··on Beetle Blocks: Visual Code for 3D Design
Yeah, it's designed for perhaps middle-school to high school aged students, and perhaps a bit younger, but also potentially intro university classes.

BeetleBlocks is built on top of Snap! (snap.berkeley.edu) which is a re-implementation of Scratch in JS that has full lambdas, continuations (call/cc), first class lists, and bunch of other CS-y ideas in a scratch-like UI.

cycomachead··on Ask HN: Is non-adjustable mobile font size a real problem?
Dear lord. This is so simple and a great idea, even if it temporarily breaks a few sites! THANKS!
cycomachead··on Ask HN: Is non-adjustable mobile font size a real problem?
Same as the above, but i have actually pushed code changes from the Github web UI before.

I at least appreciate that github gives this option.

cycomachead··on Ask HN: Is non-adjustable mobile font size a real problem?
Yep, it's an algorithm site authors have no control over. It's definitely useful, but not something to rely on as a dev.

As someone who is visually impaired, I care more about being able to READ the site than I do about nice scrolling.

I mean, I like nice scrolling / etc., please have it, but being about to read the content is a prerequisite.

cycomachead··on Berkeley CS 61AS – Structure and Interpretation of Computer Programs, Self-Paced
(A Berkeley student who went to Aki's sections -- Hi!)

One thing I've seen is that when you're first learning a langauge and pick up bad habits, they can be really hard to break. I've heard lots of students talk about the problem this causes when interviewing, especially early on. Additionally, for languages like Python, where there is loads of (often excellent) support online it can be confusing/frustrating to have a class teach one method and find answers which are mostly unrelated.

That said, I agree with what was said. Scheme is pretty amazing :)

cycomachead··on Safari is the new IE
Speech Recognition and Synthesis are in Safari -- though I don't know to the extent that it's as complete as Chrome. Safari definitely lagged behind though...
cycomachead··on Tota11y
This is the solution...

Even 'zoom' on fixed elements as dastardly as it looks is easier to read than text that is too small.

cycomachead··on Tota11y
The reader option is awesome when it exists, but there's currently no way to set a site to always enable it. Safari itself makes the determination on a page by page basis. Or at least that used to be the case.
cycomachead··on Tota11y
As some who also has terrible vision -- dedicated text sizing is awesome, but being able to just pinch-zoom makes ALL the difference for me. So many aspects of a web page are hard to use other than just text as well. (Those "X" close icons can get pretty damn hard to decipher at times.)

No solution is perfect, but allowing zooming is simple and a huge win for me. (Even if the site still has a sticky header that wont get out of the way...)

cycomachead··on Ask HN: Blue Bottle Coffee Co just raised $70M. What makes them so unique?
In SF, aside from the great coffee there are many who love the startup aspects of Blue Bottle. They went from selling at local farmer's markets to small kiosks to full shops.

I think that, in addition to what others have said, Blue Bottle has pretty big plans for itself. Aside from SF, BB runs cafes in NYC and now Tokyo. They've acquired an LA based coffee shop and now also have LA shops, Tonx Coffee and now do mail order subscriptions. Those two were maybe a year ago? Recently they acquired / merged with Tartine Bakery which is also a lovely SF establishment.

So, I don't know why, but I've got to assume someone giving them money knows something. ;)

cycomachead··on Snap: A visual drag-and-drop programming language
Yeah...it's a known issue, but a solution is apparently in the works? (low priority though.)
cycomachead··on UCB Glitterati
It's mostly (entirely?) a joke about secret societies as a response to a DailyCal article. There's a post by FooBar which gives an explanation for the site.
cycomachead··on CS 161 – Computer Security – Syllabus and important notes [pdf]
I don't know how much I can say, but 1 section of any class is 10 hours of TA paid time. Period. Doesn't matter if you work less or more.

Though, often times, most TA's I know put in far more than their required time.

cycomachead··on News Corp. Threatens to Pull Fox Off the Airwaves If Aereo Wins
Pulling Fox News off the air seems to be yet another argument for Aereo.
cycomachead··on How I Busted a Thief Who Tried to Sell My Camera on Craigslist
It depends on what pictures were on the memory card too. If you have renters/home owners insurance thefts would likely be covered. Luckily for me they were. The cost and time of replacing gear sucks, but life goes on. However, photos…those are HARD to get back. I lost 1,000 photos from a trip to Amsterdam the day after I got back. That sucks more than anything… Agreed, however, that I would never confront a seller alone in person!
cycomachead··on How I Busted a Thief Who Tried to Sell My Camera on Craigslist
Yes, it's a great site when it works. My personal camera isn't found despite uploading many images online w/ EXIF data.

I recently (two weeks) had my camera bag stolen from my apartment in Berkeley, with a few other things around $9k total and quite a few years to accumulate it. Fortunately, insurance is helping, but the police didn't even take prints in my case. Nevertheless, I'm continually stalking ebay/Craigslist/others for serial numbers and other signs as I've kept pretty detailed notes on the gear I had.

cycomachead··on List out of Lambda
Having used scheme before, and gone through some of SICP, it was neat to see the topic expressed in JS. I think it came through fine, though I'll always have a love for Scheme!
