frahs··on Google relaunches Glass for businesses
I feel like this comment missed the point of my original comment. By "music stand", I meant some device capable of holding the binder up. Consider instead a camera tripod with the top modified to hold a binder.
frahs··on The System Bottleneck Shifts to PCI-Express
Is PCIe really the bottleneck for storage devices? I haven't measured experimentally to see, but just off the top of my head, it seems like an x4 PCIe 3.0 slot should be able to keep up with everything but the latest SSD's (and for those, I'm not really sure.... depends on the workload as well probably).
frahs··on Google relaunches Glass for businesses
You're totally overcomplicating this -- all they need is literally a music stand that they keep with their binders -- when you take a binder out, bring the stand with you to the platform and mount the binder on the stand on the platform, so that you don't have to go back and forth.
frahs··on Most Waymo Patent Claims Dropped in Autonomous Car Fight with Uber
Waymo has a partnership with lyft right now, so that would be pretty tricky
frahs··on Build your own FPGA (2012)
FPGA's don't have a runtime or execution.

Think of an FPGA like a bunch of logic gates you connect.

If you have further questions I can try to answer them.

frahs··on If you can’t explain something in simple terms, you don’t understand it
As an arrogant 20-something year old, I disagree :P.

An important distinction to make here is whether you're teaching someone to intuitively reason about something or to logically calculate it precisely.

I think as long as someone grasps the basics of high school math and has a decent working memory, they should be able to learn how to calculate anything precisely given that you break it down into simple steps. If you don't know how to do that, you have no clue what you're doing.

Then there's intuitive reasoning. I think for most things, if you're familiar with a topic, you should be able to teach it in a way that makes sense. Of course there's exceptions -- some people are incredibly brilliant, but lack social awareness. I think that's the exception rather than the average case.

But not all topics are so easily reduced. There's probably some exceptions. The strongest that comes to mind is quantum computing. As many times as you can explain things like superdense coding, there's still a sense of "magic". Where the results of the math seem unnatural. And you go back through each step and try to figure out where things went weird. But each step is a logical progression from the beginning.

On that note, Michael Nielson's "Quantum Computing for the Determined" is one of the most well-taught courses I've found, and does a very good job of stepping the viewer through a very complicated topic. Michael Nielson clearly knows what he's doing :)

frahs··on The 6-Hour Workday Saves Money
It's not the skepticism. It's the lack of perspective. You can be perfectly balanced and skeptical, but your readers will not necessarily take away your perspective if you don't provide some amount of contrast/consider different opinions. If you only post skepticism, readers will just always be salty -- and it really sets the tone of discussion for the future.
frahs··on The 6-Hour Workday Saves Money
This chart in the article makes me suspicious:

https://assets.bwbx.io/images/users/iqjWHBFdfxIU/i_t8UFPOJVk...

The nurses who took 6 hour workdays took roughly the same number of sick days two years later as they did at the start. Technically they took 5% fewer days, and perhaps that's statistically significant, but it's not (for lack of a better word) interesting.

The control group is interesting! Why did a group of nurses taking a normal schedule suddenly have such a huge increase in sick days? I get the feeling that something else affected these results that we're not seeing here. I'm skeptical that the 6-hour workday explains this. Can anyone with more experience in the medical industry chime in to say if it's normal for the number of sick days a nurse takes to increase that much over 2 years (for an 8-hour workday)?

People on hackernews are always skeptical and I usually hate that. I'd like to start a trend of being appreciative. This study took two years to complete! It's hard to foresee things happening that could make the data look strange like this. Maybe they should have taken more information, so they could see which trait in the control group had the highest correlation with increased sick days. But I can't say with certainty that I would have thought to do that. Interesting study, at the very least it's an indicator that there's something interesting going on here worth investigating :).

frahs··on Climbing the wrong hill (2009)
I think the reality is more subtle than this. I'm currently working at a large company with a lot of job security. In 5-10 years, I would like to see myself working at a startup. But only for maybe 5 years max, and then I'd like to return back to a position with more security.

I think most people want to try the startup thing for only a few years.

frahs··on Silicon Valley job seekers are increasingly looking for work elsewhere
Ah yes, because big houses and with backyards are just so affordable in silicon valley ;P

frahs··on An Upgrade to SyntaxNet, New Models and a Parsing Competition
there's probably a cooler internal name for it.
frahs··on Brilliant Jerks Cost More Than They Are Worth
I think it's possible to be truthful, direct and blunt while still being nice and thoughtful. There's a false association between someone who is a jerk and someone who is willing to disagree.
frahs··on Mastering Bash and Terminal
You actually don't have to put ! In front of make. Vim has makefile integration. If all you're doing is typing make, you can do :make. For a custom build command, you can set the variable makeprg, and :make will execute that instead. On my phone so it's hard to type examples, this blog post gives more info:

frahs··on Why time management is ruining our lives
I think you're confusing being terse with being bad at communicating.

Original comment isn't talking about giving useless answers, they are talking about removing flowery language from emails and keeping them as short as possible while still giving enough info.

frahs··on Look at This Modern (C++) Sausage
All these things are exactly what's I'd do 99% of the time with the underlying calls, and I'm glad c++11 does them for me. It's like... Well duh, this is exactly the concept of abstraction.

frahs··on Amazon has made its first drone delivery to an actual customer
Why does the drone have to be wheeled out on tracks so far away from the shop for takeoff? It looks like this center may have been used for early testing where they were less confident in the drone's ability to takeoff

Also, it's interesting that they rely on fiducials placed on the ground to track the drop off point. I'd expect them to be using GPS + vision to figure out a dropoff point. Humans are really good at that, you'd think some algorithm would be good enough for 99% of the cases and save the customer time (with fiducials as a decent fallback for tricky buildings/houses)

frahs··on HackedThat: Breaking in to a hardened server via the back door
For what it's worth, I though the gifs were funny and liked them. But there's the whole tradeoff of adding extra clutter.

I a few GIFs can definitely split up the article a bit and make it easier to read, but too many can also be distracting.

frahs··on Latest to Quit Google’s Self-Driving Car Unit: Top Roboticist
Their hands probably always have to be on the joystick, following it's motion. That way if anything goes wrong, they can take over faster. That doesn't mean the car isn't in auto-drive.
frahs··on China’s scary lesson to the world: Censoring the Internet works
There's a difference between biased reporting and citizens being forbidden from talking about something online.

If you made the same post but about some Chinese politician and in China, you could get in trouble for that.

frahs··on For anyone who has been turned down by 38 companies
What are you more afraid of? Rejection from a company you never have to talk to again OR your family being unhappy as a result of you 1) being unhappy with your job 2) feeling like you aren't doing as much as you can or should.

This might just be something you have to confront. But I think constantly confronting your fears is healthy, even if it's difficult and stressful.

It sounds like you're genuinely enthusiastic about engineering and computer science. I think talking about your side projects (deep learning, blockchain, etc) will show this very effectively. Actually, having side projects to talk about is sort of like a secret weapon at job interviews. You'll find if you learn how to talk about these your interviews will go really well, so long as you can do a somewhat above average job on the technical questions (which can happen with practice and luck).

That being said, I can't give much help on being shy as I've never really dealt with that. I did used to be kind of.... not the best with social situations, and I found that by being chatty and going out of your way to meet people randomly, you end up getting good at it pretty quickly. Of course I sucked at this at first, but I had a friend who was extremely chatty and whenever we hanged out in public he would always be talking to random people. By joining in I sorta got the hang of it, and that helped a lot.

Also never be afraid of being silly. Making mistakes can make people feel more comfortable around you because they stop worrying about keeping up their own image of being a normal human being (what does normal even mean?). That works more for meeting people and MUCH LESS in job interviews, but meeting people will make you less shy, which in turn can help with interviews.

Don't fall into the trap of believing you can't change yourself. Simply by acknowledging what you'd like to change about yourself, you've already begun the first step. I think you already know you need to do something. Hopefully this is the impetus. I've seen friends totally change personalities and go from being shy to confident, or silly to mature. You can overcome your fear of rejection. Just get rejected a lot so that it becomes a trivial thing you can laugh at.

frahs··on My 5.5 Months on Soylent: The Joys of Not Cooking
I like cooking too. But a lot of the times for lunch I don't feel like making something. Then I have to bring it with me to class and that means there's an extra container to clean at the end of the day. Also, I don't usually have time to make much in the mornings.

Soylent works as a perfect meal substitute for when I'm lazy or short on time, and that means I have more time and money for when I want to have a nice meal.

frahs··on Breakthrough bionic hand restores amputee’s sense of touch
I believe we've had technology similar to this for a long time, is there anything new with this in particular?

I believe the biggest problem is the formation of scar tissue around the implanted electrodes. This reduces the strength of the electrical signals over time, and eventually the electrodes need to be adjusted.
