DrJ··on Ask HN: What's left for early startup engineers as the company grows?
You will need to fit into one of those positions (if it makes you happy) or leave. You have a valuable set of skills and it's a great time to work on your own ideas.

I am currently in a similar boat as you.

DrJ··on CloudAMQP experiences ops nightmare today
So I just read this, the CEO added the below

    insts = [
      @ec2.instances.with_tag('Name', "CloudAMQP-#@name0*").to_a,
      @ec2.instances.with_tag('Name', "CloudAMQP-#@name-*").to_a,
      @ec2.instances.with_tag('Service', 'CloudAMQP').with_tag('Name', "#@name-*").to_a,
    ].flatten
unless they have a variable named "@name0" that first line would've evaluated to "CloudAMQP-*", which would then have the fun happen.
DrJ··on Show HN: Our Bayes Impact Hackathon Project, MineData.org
and here I thought it was about land mines.
DrJ··on Why Did Yishan Wong Resign as Reddit CEO?
>> i.e. how stressful is too stressful, until multiple outside people and coaches I was working with remarked to me that I looked incredibly worn down for months on end and it wasn't supposed to be this hard.

@sama did just tweet about saying you look tired[1].

DrJ··on PgOSQuery: Expose the operating system as a Postgres database

DrJ··on Opternative: Eye exams from the comfort of home

DrJ··on Bash bug: apply the unofficial patch now (CVE-2014-6277)

DrJ··on Cloud Server Reboots
the Xen vulnerability must be something severe if they are all doing this. [1] http://xenbits.xen.org/xsa/
DrJ··on California High-Speed Rail No. 9 – the Chairman's Turn Again
don't forget to add costs for getting TO the airport. BART costs ~$15 (for either Oakland or SFO), by cab (Uber) ~$50. So while $250 might be on the upper side of things, I think $150 isn't exactly right either. so the low $200 range.
DrJ··on YC Demo Day Session 3
neptune.io's seems to be providing the solution that someone didn't fix during the day whenever an alert fires.

out of disk space -> clean up your disks (e.g. logrotate)

process crash -> should be using a process supervisor

low cpu utilization -> autoscaling

DrJ··on Announcing Docker 1.1.0
may I interest you in dvm [http://hw-ops.com/blog/2014/01/07/introducing-dvm-docker-in-...]

it's not native, but it makes playing with docker containers from mac osx straight forward.

DrJ··on Show HN: Vim Awesome – Vim plugins
I guess it's good that my Vundles are basically the top 10. Ha!
DrJ··on Awesome Sysadmin: Open-source sysadmin resources
For anyone interested there is also https://github.com/opsschool/curriculum
DrJ··on Celery – Best Practices
I'd also add: Be wary of context dependent actions (e.g. render_template, user.set_password, sign_url, base_url) as you aren't in the application/request context inside of a celery task.
DrJ··on My first Ruby project: a BikeIndex.org API integration for Twitter IsItStolen
isn't (3.) 'knowingly' buying stolen property that is illegal? but 'unknowingly' buying stolen property would at worst mean you will have to surrender the property to the original owner?
DrJ··on Processes Paralleling to Speed up Computing and Tasks Execution in Linux
why doesn't the person just use 'time' to show how long it took instead of saying off the cuff 'saved X seconds'
DrJ··on Using Facebook Notes to DDoS any website
first time I'm seeing this post, but also now I found out there is another portal for HN. Thanks!

this is literally happening in this thread
DrJ··on Bad Password Policies
American Express also has 20 character limit, but for more fun they are case insensitive.
DrJ··on Ask HN: Who is hiring? (April 2014)
San Francisco - Heyday - http://hey.co

We are building a lifelog for people to remember and share the story of their lives, automatically, beautifully, and privately. Two months ago, we launched here on Hacker News [ https://news.ycombinator.com/item?id=6858373 ]. Here's what some of you guys said:

- "Wow. I rarely download this stuff. But the fact that it claims to be automatic piqued my interest. After downloading it I can say that my first impression is shocked. Shocked that I really liked it."

- "This is very well done. This could crush Facebook. Not in the short term but if you create a timeline that is more personally valuable to people they will be far more likely to use it and share it with friends and family. Your timeline is already far more interesting then my "Wall."

- "Why is it free? I would've paid for this."

- "I have been looking for this. I've been so desperate for this I've been contemplating creating it myself."

We're looking for:

* Mobile engineers (iOS - hard problems include making our sync engine fast/reliable, fast/intuitive search for memories, surfacing important memories in the background, UI performance, and doing it all without using a lot of battery)

* Systems engineers (Python, AWS, Puppet/Chef - hard problems include delivering accurate geocoding for memories, reliable syncing, and building systems to monitor and scale all of it automatically)

* Data scientists (R/Matlab/SPSS, Python, SQL, statistics, machine learning - hard problems include using ML to improve accuracy of geocoding, building growth and retention models, all while guaranteeing user anonymity and privacy).

We will fly you out for interviews and relocate you to San Francisco if you aren't here already. A lot of our team work remotely from time to time, but we haven't found full time remote employees to work out well for us since we collaborate so closely together in real time.

Please email us directly at siqi at hey dot co (8 hour SLA for a response).

DrJ··on Larry Page: I’d Rather Leave My Billions to Elon Musk Than to Charity
can all the rich people buy all the telcos and make internet more neutral?
DrJ··on Soylent Update 3/13
It's odd that whenever I see an update from Soylent I already assume that it is an 'Soylent will be ready next month maybe' email.

I'm hoping to be surprised in April, but then I was also today, last month, January... etc.

DrJ··on How times have changed for PostgreSQL
I would contest 'better python driver' with SQLAlchemy.
DrJ··on Call for acid-bath stem-cell paper to be retracted
and some would argue that you place a lot of focus on the artifact (manuels) than on creative thought.
DrJ··on Police sound all-clear after Facebook evacuation Tuesday night

DrJ··on ZenPayroll's (YC W12) advice for B2B companies
I'm really impressed by ZenPayroll's 2 factor auth support :)
DrJ··on Rubygems.org AWS bill for Feb 2014 [pdf]
bandwidth is free in the same region, but not across regions.

*edit and I believe not if you end up using the public IP address instead of the internal ip address.
