DanFeldman··on Glass Enterprise Edition 2
IIRC, some jets/planes were being repaired by mechanics equipped with Google Glass. It would help out by bringing up schematics while the technicians were doing their thing on the plane. But it was a very fluffy article that seemed more native advertising than content.
DanFeldman··on Netflix Saves Kids from Up to 400 Hours of Commercials a Year
Good riddance. The last time I watched TV with ads was for the superbowl, and even those nicely produced ads I found absolutely grating. There's no way I can go back to ads between tense moments in TV shows. It's like seeing the internet with an adblocker for the first time.
DanFeldman··on Harry’s Will Be Sold to Owner of Schick for $1.37B
I bought a cheap shower mirror in target and it's been a life saver. Definitely worth the ~10-15 bucks.

Starsky Robotics (YC S16) | Sr Software Engineer, ML Validation, SWE - Infra, Controls Engineer, Behavior Planning Engineer | San Francisco, CA | Onsite, INTERNS, VISA | Full-time

Come build self driving trucks! Starsky Robotics is a fantastic place to work, we're solving hard problems across the board and need help. We have positions open for all sides of the robotics stack, and are specifically looking for more Software eng. maturity for the platform and infrastructure teams. I personally work on the Infra side and am looking for extra hands on our data, simulator, and fleet management infrastructure. Interns welcome to apply as well!

We recently opened ~5 new Software positions across the Truck systems.

Blurb:

We're working to make trucks autonomous on the highway and remote controlled by experienced remote drivers for the first and last mile. Our self driving trucks will make roads safer while giving drivers meaningful work close to their homes and families.

We currently run our trucks autonomously on the highway, with freight. We are looking for awesome engineers who are comfortable working on a scrappy, driven engineering team.

We use Python, C++, and lots of bash scripting. We are a group of PhDs, masters, bachelors, college dropouts, and high school interns all working together. No matter your experience, we're looking for intelligent folks who have a history of diving excitedly into new fields. We can sponsor visas. All positions non-remote unless otherwise specified.

Apply online, every application is read: https://jobs.lever.co/starskyrobotics/ or email me (daniel + @<company_name>.com) with any questions, but do not send me your resume (please apply instead online).

DanFeldman··on A Measles Case Hits Google's Silicon Valley Headquarters
> In 2015, Wired reported that one daycare at Google had a 68% measles vaccination rate, although Google contested the accuracy of the article at the time.
DanFeldman··on You Are Not Google (2017)
Exactly same case here - we're using Athena (packaged presto from AWS) and have a Postgres instance w/ identical data in a different data model. Presto is mindblowingly good at the low latency queries and scales well to anything nontrivial. It seems opening files for reading is the biggest source of delay in presto! Postgres is not handling the scale well, but it was a nice experiment.
DanFeldman··on No one should have to travel in fear
For what its worth, SFO does not use the TSA [0]. The posted article does not mention the TSA at all, only Border Patrol and Customs agents. I've had terrible TSA experiences at other airports, but never a problem with the security at SFO.

DanFeldman··on Season of Docs
I would absolutely pay for this. If i could walk through verbally how everything works on a large system I'm working on with a company, and then magically get some confluence docs, diagrams, autodocs, readmes, guides, this would be incredibly valuable.
DanFeldman··on Facebook exploit – Confirm website visitor identities
Being charitable here, it may be that this exploit showed a breakage in their internal API security process, or an edge case previously unhandled. Perhaps FB had to run an internal audit to find any other endpoints effected by this bug. Buggy endpoints then need to get fixed, tickets get sent out, but with a low priority because this is a low priority bug, and voilà, 6-9 months.
DanFeldman··on Amazon Translate
Then again, ELB was amazing a few years back when the tooling for dealing with AWS/GCP/Azure was not as mature. ELB wrapped a huge percentage of the use cases (webapps) in one or two configs.

Sure, now there's a ton of better/more scaleable/cheaper options, but ELB was great before.

DanFeldman··on UC terminates subscriptions with Elsevier in push for open access
To color this even further, at UC Berkeley I had intro courses with 1,200 students.

DanFeldman··on Launch HN: Searchlight (YC W19) – Hiring based on past performance, not resumes
This is very cool, shared with my team. I am worried about bias in the results questionnaire - both biased against and biased towards the candidate. How do you plan to avoid extremely damaging and false information from getting in? One bad review is now a black spot on a candidate. Dipping into black-mirror rating territory...
DanFeldman··on Simdjson – Parsing Gigabytes of JSON per Second
We use Athena for all our robotics data, which we ETL into JSON. It's fantastic for queries that are simple time-slice queries, as most are because sensor data is inherently time-series. When more complicated joins are necessary, the performance is there across terabytes, and the cost is very very low, $5 per terabyte scanned (storage costs are another thing).
DanFeldman··on Intern at a YC Company
Can you email me at daniel@starskyrobotics.com? I'm sorry to hear you had a bad experience - that does not match how we aim to recruit and no one should get lost in our process. I personally hate companies ghosting people - we don't do that.
DanFeldman··on Intern at a YC Company
On behalf of YC or Starsky?

For YC, it was pretty damn slick, but made possible only because a close-knit bond between companies exists to an extent. I remember being super interested in self driving cars, really wanting to work at Cruise and getting their founders email from a YC Partner at the dinner. I was just out of my freshman year, and extremely nervous about emailing the cruise folks, and some of my coworkers at LeadGenius helped me draft intro emails. They were just really great people. My managers at LeadGenius (YC alums themselves) were the first people I told when I got into the fellowship. There were a lot of signals along the way that the folks involved in YC, from the partners to the founders, were __good__ people. I wanted to be part of that. And still am, and still do.

DanFeldman··on Intern at a YC Company
I interned at a YC company as my first internship (LeadGenius, YCS11) before they had this organized a program. I had no idea what YC was before I applied, and learned about YC and HN later. The YC dinner was great, ended up making some connections and eventually applied to YC Fellowship two years later and went through myself. The YC network has been great for me, and it all started with an internship within a portfolio company.

I'm at another YC company, Starsky Robotics now, and we're open for interns! Come join and build self-driving trucks.

DanFeldman··on GitHub Classroom and Travis CI Improved Students’ Grades
Yup, but using Travis as the platform for an autograder makes it A LOT easier for teachers/professors with less access to dev time to implement a great iteration platform. At Berkeley our intro classes had world-class infrastructure autograders (release I believe as ok.py https://okpy.org/) - but I imagine less staffed courses could benefit from a workflow like this. Plus, it gives students the benefit of familiarity with actual tools that are in use in the industry.
DanFeldman··on When AWS Autoscale Doesn’t
We use a ton of ECS, for running batch processing for our data pipeline, 4ish small internal webapps/microservices, and our Jenkins testing compute.

Some of the problems we're seeing is task placement and waiting is too hard (we had to write our own jittered waiter to not overload the ecs api endpoints when asking if our tasks are ready to place). Scaling the underlining EC2 instances is slow. The task definition=>family=>container definition hierarchy is not great. Log discovery is a bitch.

Are these all solved under K8S? I've no experience with kubernetes, but if so, might need to rethink where we run our containers. ECS was just so easy, and then so hard.

DanFeldman··on Scientists cut the tolerable intake of PFAs by 99.9%
Same here - I have a bigger stainless steel skillet that always needs steel wool to get some pesky things out of it after any frying, but my cast iron cleans up much easier. Though, I make liberal use of dish soap and the scouring side of my sponge. Never had a problem with seasoning other than roommates messing it up a bit here and there.

DanFeldman··on Snap CFO Tim Stone Is Resigning
I was a huge user of snapchat, even though my phone (Nexus 5x) was so painfully slow on it that I hated using the app. I got a lot out of it (keep up with actual friends lives, I don't use instagram). After the redesign, it was bad enough to tip me over the edge. I haven't opened it in months, and I miss the friends I kept in touch with it.

DanFeldman··on Analyzing Hacker News book suggestions in Python
I read the trilogy English translation. I sometimes had trouble following individual characters with similar names, but it didn't impede my comprehension. Fantastic series, 11/10.
