KRuchan··on Tailscale SSH
I attempted this on a VM inside a Linux host and got a lower privileged user from inside the guest VM to ssh to a root-privileged user outside on the host. Both were authenticated to Tailscale with the same gmail account, so from an OAuth perspective, this is valid. From the OS perspective though, the host SSH port is blocked, and a guest should never get full root access to the host or see the host's resources.

I am not sure if I am confused about something, or maybe there are prod use-cases where the same IDP identity should have different roles/privileges depending on the machine, and Tailscale SSH breaks that?

KRuchan··on ASK HN: Has anyone adopted Chrome OS as their primary OS?
You might want to try the Pixel Slate as a iPad Pro replacement as that would fix most of your issues. Several folks report doing this here: https://www.reddit.com/r/pixel_slate

KRuchan··on Ask HN: What book have you given as a gift?
"The Defining Decade" by Meg Jay to anyone in their twenties.

Shameless plug -I posted a summary here: https://rkirti.wordpress.com/2015/12/05/learnings-from-the-d...

KRuchan··on Ask HN: Best book (or other media) to learn lua from?
Not a book, but if you are looking for a real-world motivation for a lua project - try out awesomewm, a window manager thats customizable using lua. You'll write some lua scripts and end up with a workspace to your liking.
KRuchan··on I made my own clear plastic tooth aligners and they worked
Most orthodontists will say anything except water is a no-no - coffee and tea will stain your aligners, and they almost always permeate the aligners into your teeth, causing decay until the next brushing. Juice is even more harmful with the sugar and fibre. Also, hot beverages can deform the aligners. I know cases of people who tried having drinks with straws, and realized it wasn't a viable solution. The drink still ends up permeating the aligners.

Could you share a link if it can be bought online?

Kudos to him for doing this, but I am slightly concerned that he has introduced overbite [1] in his jaws looking at the before and after pictures :(

KRuchan··on Ask HN: What is something someone said that really changed your way of thinking?
Read in a book: "If you spoke to your friends like you speak to yourself, would anyone ever want to be your friend?" ("Living with a heart wide open"). The line instantly changed my self-talk from negative and dystopian to compassionate and constructive i.e. things like scolding myself when I missed a freeway exit while driving. Turns out my case is not uncommon - most people call themselves stupid 8-10 times a day.
KRuchan··on Ask HN: Who is hiring? (August 2015)
Love the perks section of your webpage. Very apt!
KRuchan··on Ask HN: How Do You Make the Most of Your Commute?
Hit the local library for audiobook CDs. I agree its old-fashioned, but my 2012 Honda Civic has a CD player and the Menlo Park library had some great collection of tech/business audiobook CDs. I began experimenting with playing them on the drive to work and am pretty happy with the results.
KRuchan··on Announcing The Fog Creek Fellowship
Great initiative. Reading Joel's blog was a fun and inspiring part of growing up in the programming world. As a woman in CS, I look forward to see this expanded to allow more of us to participate, not just NYC residents.
KRuchan··on Cylinders in Spheres
Maybe I am missing something here, but why is 1 a neat problem? You are increasing the radius by 1 meter so the length of the band is now 2pi(r_e + 1) making the increment 2*pi meters. Is the surprisingly low increment the point of the problem?
KRuchan··on Google Invests $50M in “Made With Code” Program to Get Girls Excited About CS
The public face for Girls Who Code is Reshma Saujani (law / politics background). As krstck pointed out, the public faces here are Mindy Kaling, Chelsea Clinton. While there are engineers involved behind the curtains in each of these programs, I don't like the fact that the ones who stand to gain the most (publicity, credibility, funding, access to resources and powerful contacts) are people who don't have anything to do with tech themselves except flying around the country giving talks about how everyone should code (Reshma Saujani, I am looking at you). I am being bitter here, but I would hope to live in a world where real engineers are the women in the limelight for the kids to look up to.
KRuchan··on Google Invests $50M in “Made With Code” Program to Get Girls Excited About CS
This. I am a woman in engineering and share your sentiment. Can't describe how annoyed I have been to find non-engineer/non-programmer women beat the drums about getting more girls to code or more women into STEM while the actual deserving technical women toil away silently.

KRuchan··on Amazon Fire TV
The box has a snapdragon 600 chip in it, so not exactly underpowered. They also seem to be addressing the 'immersive' segment more than 'Candy Crush' type of games - they mention Asphalt 8 will be supported soon and Amazon has been hiring/acqui-hiring AAA-title devs for broader support since a while now.
KRuchan··on Securing a SoC is Not Easy
@jwr: Sorry for the delayed reply, was down with a fever. (Posted the info below in a separate comment, in case anyone stumbles across the thread later). 1. http://www.intrinsyc.com/products/qualcomm/dragonboard-devel... Intrinsyc is one of two partners who offers "Dragonboards" with the latest (so far, that will change soon) SoCs (APQ8064 and contemporaries). AFAIK, these boards can be ordered in any quantity from 1 to 100s, so they should be a good start for a development kit. Intrinsyc offers a Linux distribution for the 8074 SoM. Not too sure about the maturity of Linux support, but I am expecting updates in the near future, and will post them here. For those who need to eventually build their own boards using Qualcomm SoCs, Intrinsyc's FAQ here should be useful: http://www.intrinsyc.com/products/qualcomm/dragonboard-faq.a... 2. Inforce computing also offers a cute board with the APQ8064. http://www.inforcecomputing.com/product/qualcomm.html

Not sure if these offer the level of detail/support that folks here are looking for, but they seem like a good start.

Engineer at Qualcomm here - I did check with our biz dev folks and we have mechanisms in place to supply in smaller quantities (a few hundreds..)
KRuchan··on Securing a SoC is Not Easy
I am not familiar with the categories/collections of games Open Pandora caters to, to answer that. I would definitely recommend a high-end chipset (SnapDragon800/600)for someone building a gaming box. On the other hand,I see on wiki that Pandora intends to support older games through console emulators, so an older/cheaper GPU should be fine if those are the bulk of the targets.

How do I reach you? Not too happy sharing a company/personal email address here and my name is too complicated to describe my ID in a email-address-extractor-safe way.
KRuchan··on Securing a SoC is Not Easy
Emailed you at your cryptoseal address.
KRuchan··on Securing a SoC is Not Easy
Is there anyway to reach you? The form throws an error when I hit submit (I think you did receive my form,just that the 'thanks' page url is messed up)
KRuchan··on Securing a SoC is Not Easy
Done.
KRuchan··on Securing a SoC is Not Easy
Yes, would be happy to talk with your colleague and point him to the right contacts. I am at the San Diego headquarters.
KRuchan··on Securing a SoC is Not Easy
I work for Qualcomm and am surprised that the blog post author didn't consider our SoCs - it would meet all the requirements and I believe its not too much hassle to source from us.
