jcurbo··on Docker operations slowing down on AWS
I always think of this as the "Stack Overflow approach" since I was listening to their podcast when they were building it and that's what they elected to do: https://blog.codinghorror.com/building-servers-for-fun-and-p...
jcurbo··on Dell 38 inch UltraSharp monitor
Another U3415W owner here, it's the best monitor purchase I've made in years. I previously had a 27" and two 24"s and replaced the 24s with the U2415W. I do programming and gaming on it and it's excellent for both.
jcurbo··on 42-inch yacht still hoping to become the smallest boat to cross the Atlantic
Two of my favorite books about sailing are:

Sailing Alone Around the World https://en.wikipedia.org/wiki/Sailing_Alone_Around_the_World about Joshua Slocum, the first person to sail around the world alone

Confessions of a Long Distance Sailor https://arachnoid.com/sailbook/ about Paul Lutus sailing around the world alone from 1988-1991

Both are interesting kind of like Maidentrip (which I haven't seen, will have to check out) - visiting different cultures, limited technical means (although Paul did have a computer, TV, VCR...).

jcurbo··on Unmanned U.S. Air Force space plane lands after secret, two-year mission
Risk reduction - pretty well explained above. Experimentation - Standard definition. Trying out stuff. Concept-of-operations development - take the experiments and turn them into instructions and procedures for normal operations. Think of it as production compared to experimentation being dev. (concept of operations is a standard document describing the 'how' of something, typically in a tech-agnostic way)

Basically they are using this vehicle to figure out how to do this stuff with future vehicles in a scaled-up way.

jcurbo··on My son died in 1994 but his heart only stopped beating this year
It's still a thing, see: http://www.redcrossblood.org/donating-blood/eligibility-requ...

I lived in Germany for three years in the '00s so I'm ineligible.

jcurbo··on Chicago's About to Get a Lot Less Orange
The main issue I've heard about is that LEDs are generally more wide-spectrum than sodium vapor lamps. This leads to a lot more sky glow (light pollution). There's a good webpage about this here: http://www.flagstaffdarkskies.org/for-wonks/lamp-spectrum-li...
jcurbo··on An Oral History of Something Awful
Much like Reddit, the value at SA is in niche sub forums. I haven't looked at GBS in years but still visit places like Ask/Tell, Book Barn, etc as well as specific game threads. (Is this like advanced "there's a front page?) I bookmark them and visit via the control panel pretty much exclusively. Big threads are like communities, especially around specific games and TV shows. It's wild to me that SA is still a thing after all these years (I started in 2001) but I think the site has been through so much that it can survive anything these days.
jcurbo··on What’s New in Bash/WSL and Windows Console
iterm2 on OS X is really good, maybe the gold standard as far as I'm concerned.
jcurbo··on Amazon's Tepid Response to Counterfeiters Frustrates Sellers
Mother Jones did a major piece on this several years ago.

jcurbo··on Code.mil – An experiment in open source at the Department of Defense
It is surprising to people outside the DoD, but most applications are exceedingly mundane - I would lump a lot of them under "database frontends," like personnel, finance, and logistics systems. One problem there is that, in many cases, DoD or its contractors end up writing custom code for those things rather than using existing solutions, so projects get delayed as feature creep sets in. There is a bigger push for using commodity software but it's slow in coming.

For things where you truly need custom code - like missile guidance systems, avionics, specific process oriented tools for crunching data (intel or otherwise), open sourcing the core application is probably not going to help anyway. One problem though is that, increasingly, people want to use open source libraries for things. Take the data crunching - people want to use R, Python, Hadoop, whatever. This is where people are running into issues. And good luck getting those tools into close environments (e.g. classified networks) - many places do not have the resources in manpower or expertise to custom build the environments they need, so they couldn't use the newest shiny stuff even if they wanted to, even if their IA shop allowed it.

As to your last question, not a lot of examples to mind (maybe Accumulo like someone mentioned elsewhere), but another factor is that there are few programmers that are actually DoD civil servants - most stuff is written by contractors and DoD folks don't usually have the experience or knowledge necessary to even understand what they're getting at a technical level in order to recognize that what they have is something worth open sourcing (which might take some work). I'm not saying it's bad everywhere - I have met some pretty awesome technical folks that were GS's - but it's very uneven.

jcurbo··on Code.mil – An experiment in open source at the Department of Defense
As discussed elsewhere in this thread, acceptance of open source is very much an agency-by-agency deal within the DoD. IC orgs have pretty wide latitude to do what they want and NSA even more than others because of the primacy of their mission. Accumulo is widely used within the IC so it was to NSA's advantage to let it out - no doubt they did not want to maintain it themselves. Many orgs don't want to take on the burden of maintaining something, especially in the current budget climate where they'll have to go fight for $$$ and probably drop some other mission to make room.
jcurbo··on Code.mil – An experiment in open source at the Department of Defense
For some reason the AF seems to have draconian web filtering in place, compared to other places I have experience with. In the late 2000's when I was still on active duty, we used to complain about having to look stuff up at home because when you'd go to search for a tech solution and it was on someone's random blog, 9 times out of 10 it'd be blocked. It was extremely frustrating.
jcurbo··on Cloudflare Reverse Proxies Are Dumping Uninitialized Memory
Thanks for posting here, I was explicitly looking to see if anyone mentioned Fastmail after I saw it on that Github list. You might want to post something on your site if you haven't already, kinda like 1password did.
jcurbo··on Intel’s Atom C2000 chips are bricking products, and it’s not just Cisco hit
Had the same thought. The article mentions the 1815 but I have a 1515 which apparently has a C2538, which is one of the models listed.

jcurbo··on Ask HN: Need help with job offer negotiation
That just happened to me too (just accepted an offer for a new job). When they asked I politely told them I would not share that info, but I would tell them what range I'm looking for. It worked out fine.
jcurbo··on VESA HOTAS Mounts for IKEA Markus Chair
Thanks, much appreciated.
jcurbo··on VESA HOTAS Mounts for IKEA Markus Chair
Can we get a quick review? It looks really interesting but looking around the net I can't find many people talking about it. Does it wobble any? What joystick are you using on it? What kind of chair do you use with it?

(Warthog + Obutto Ozone owner here but thinking of simplifying things)

jcurbo··on Announcing Rust 1.14
So, I see tons of unwrap() in Rust code I've looked at in the wild. I understand the concept of unwrap() and Option types. What would this type of code look like with proper error handling? It seems like it'd devolve into a ton of if-then statements like in C.
jcurbo··on “Removal of powerpc as a release architecture”
I didn't go look but that was going to be my guess. Since Debian is volunteer-ran, each architecture needs people to manage it, as well as having adequate hardware to test/build on.
jcurbo··on Music Theory: An Education from First Principles
As someone just getting into music theory the interactivity is extremely nice. The visualizations and sound just click for me.
jcurbo··on The New York Times is buying the Wirecutter for more than $30M
As long as they don't change their format I'm ok with this. They seem to go to a great deal of trouble to discuss all the possible options, and criteria they used to write their recommendations. That allows me to judge for myself to a degree which I really like. Several times I have not bought their recommendation and have gone with something else because I felt like I was more informed about what I was looking for from reading their article, which is still good in my book.
jcurbo··on Music theory for nerds
As someone self-teaching themselves piano, this is really fantastic. I already play drums but have no notion of what notes are what on a staff and piano keys and have been slowly teaching myself. The MIDI keyboard support really makes this stand out.
jcurbo··on Faking your death
I was an officer, but went to Officer Training School (OTS) which is a 12-week boot camp kind of approach, and I came to post similar thoughts. My dad was in the AF so I knew there was some level of BS to deal with, and just put up with it until I finished. I looked at it as a small price to pay to have an opportunity to get out in the world and do something better with my life which has paid massive dividends ever since.
jcurbo··on California bans ITT tech from accepting new students
All true. The Post-9/11 GI Bill was a large driver of this - if you've done your time, it's basically free schooling and all you have to do is sign up. The govt sends the tuition money directly to the school, you just have to recertify with the VA every semester. (In the old GI Bill you got the money first, and the rates were different)

jcurbo··on The Fall of Avalon Hill (1998)
Still alive and kicking it seems. http://www.dreamwizards.com/
jcurbo··on How to make Slack less bad for you
On my Windows Slack client, it says "Message #general". Same when I log into Slack via Firefox.
jcurbo··on DoD Encryption Wizard
I haven't found one, but I suspect the IASE page is only over HTTP for legacy reasons, as there are lots of things that download stuff automatically from DISA. I could be wrong though, and I agree that it should be served over HTTPS. The main DISA page is served over HTTPS: https://www.disa.mil
jcurbo··on DoD Encryption Wizard
MilitaryCAC is not an official source, it's about using CACs on personally-owned computers.
jcurbo··on Backyard telescopes and amateur eyes see where “pro” astronomers can’t
This extends to more than just planets, too. The University of Maryland Observatory runs a summer program for amateur astronomers that I signed up for this year, and we're learning how to do exoplanet transit detection. There are databases to look up candidates and ways to submit data to reinforce findings. It's doable with typical telescopes available to amateurs, and the observatory has a few larger scopes we're learning to use. One of the professors at UMD has written up guides on how to do it: http://www.astrodennis.com/

Other efforts like this include: - American Association of Variable Star Observers https://www.aavso.org/public - Center for Backyard Astrophysics http://cbastro.org/

and I'm sure there are others I don't know about.

jcurbo··on Polycom’s co-founder on the best investment he ever made
I find it interesting that you still thought of RS as a choice. Has there been a RS you could go to for components or soldering stuff any time recently? I haven't seen one that wasn't more than just an electronics store like Best Buy in over a decade if not more.
