JoshuaJB··on United Airlines Domestic Flights Grounded for 2 Hours by Computer Outage
If the datacenters are really too complex for the people running them to understand, I would expect failures like this to drive the airlines towards AWS, Azure, or some similar service.
JoshuaJB··on Ask HN: Why are flash memory prices going down so much faster than RAM?
For other readers wondering what SLC, MLC, TLC, and QLC stand for:

SLC -> Single-Level Cell

MLC -> Multi-Level Cell (now mostly means 2-level cell?)

TLC -> Triple-Level Cell

QLC -> Quad-Level Cell

It seems like a lot of the higher-level cell designs require a '3D' gate architecture, so you might come across that terminology in marketing materials.

JoshuaJB··on Nikola Motor Company
The company's Facebook account only appeared on May 1st and their Twitter sometime since then [1][2]. It also appears that their website only became public on May 4th [3]. Given the recentness of their public presence, I would not imagine that they were expecting this much publicity yet.

I think that they are legitimate because the "What's Inside" photo for the Nikola One is definitely an export from a real CAD model [4]. And Google Image search cannot find the photos they have on their social media profiles used anywhere else besides when referring to them [5]. That said, they seem distinctly in the prototype phase and have a long way to go before actually shipping something. Tesla took 6 years to ship less than 150 cars. [6]

JoshuaJB··on Microsoft no longer allows admins to block Windows Store access in Win10 Pro
From what I've seen, Google's desktop Linux systems are just customized LTS Ubuntu images. (Source: visits to Google office) They appeared entirely normal, eg. Unity, Gnome Apps, etc. but I am sure they made some Google-specific changes.

Also, Valve released their Linux distro awhile ago. [1] And Phoronix [2] has some good Windows vs Linux gaming benchmarks. My impression was that they were getting pretty comparable.

JoshuaJB··on Model 3 Unveiling [video]
In comparison, Nissan only sold 170k LEAFs from 2010-2015.[1] Three years of Nissan LEAF sales in 24h? Fantastic!

JoshuaJB··on First Impressions of a $9 CHIP Computer
I have a friend who has one of these, and he's stopped using it entirely because of unreliability. The WiFi performed poorly (e.g. in same room, on same router, multi-second latency) and the radios seemed to crash to the point of requiring a hard reset after a few days. Another thing he mentioned as an annoyance (that may be fixed now) was that the power state can't be controlled from software (e.g. shutdown -r will hang when it actually tells the hw to power-cycle).
JoshuaJB··on ChakraCore GitHub repository is now open
It doesn't look like it builds yet. See https://github.com/Microsoft/ChakraCore/wiki/Roadmap.
JoshuaJB··on Show HN: Particle Simulation with OpenGL compute shader – 8M particles
"In the future, we are committed to bringing it to other platforms, starting with Linux..."

Nice to see a change of heart.

JoshuaJB··on Amazon has no idea how to run an app store
I've had a good experience with the web app [1]. It's a surprisingly well designed piece of software compared to it's competitors (e.g. Spotify or Pandora). The library could definitely use better curation though.

JoshuaJB··on Openage – Free Age of Empires 2 engine clone
Technically it's 0 A.D., but that's a minor note. For those unfamiliar with the project, check out http://play0ad.com. It's a very mature codebase with over 10 years of development behind it. Everything is free as in freedom. One area they excel in that many other open-source games struggle with is in the quality of their models and art. I even know several other open source games which re-use the models.
JoshuaJB··on os.js: JavaScript Cloud/Web Desktop Platform
Just an X11-client would be interesting. It would theoretically allow you to transparently offload UNIX applications to a remote server.
JoshuaJB··on Glassdoor: Airbnb dethrones Google as the best tech company to work for in U.S
I visited Airbnb's headquarters this past summer, and they are very impressive. For example, their conference rooms are themed off actual listings. So you have the African hut meeting room, the elegant Milan room, and the tiny Japanese stress relief space. On top of that, their hallways tell stories. For example, one describes the origins of their logo in beautiful, exquisite detail. Overall, I have yet to see a more creative workspace.
JoshuaJB··on I gave my students iPads – then wished I could take them back
I would argue that in this case it is a waste of education budget. Their high cost and non-core use sounds like it raises costs without cutting anything. For technology to work in the classroom, it needs to be attractive to administrators.
JoshuaJB··on 0AD Pathfinder Design [pdf]
Engineers have presented some of how their algorithms work at conferences and in other places.
JoshuaJB··on 0AD Pathfinder Design [pdf]
Yep! It's based pretty heavily off how AoE and later games do it.
JoshuaJB··on This Is Not a Day Care. It’s a University
> with plenty of "kids these days" rants

I'm a student at a top 4 year university, and I find the lack of student backbone nauseating. The current trends in university culture go entirely counter to the reasons that we have higher education. Instead of encouraging expression, our culture deafens it with its constant concern towards avoiding offence.

JoshuaJB··on 0 A.D.: A free, open-source game of ancient warfare
We'd love help in any of those areas! If you'd like to help with programming, take a look at [1]. For other areas, the processes is less structured and I'd suggest starting on our forums [2]. In both cases however, jump on our IRC channels if you have any questions (#0ad and #0ad-dev on quakenet).

In terms of where we most need contributors, at the moment I'm not aware of anyone working on campaign storyboarding or UI mockups.

JoshuaJB··on 0 A.D.: A free, open-source game of ancient warfare
Just the long-range one in this release[1], but the short-range replacement is targeted for the next[2].

JoshuaJB··on 0 A.D.: A free, open-source game of ancient warfare
Campaigns are on the roadmap. All the required code to support them is complete, we just need to build the scenarios.
JoshuaJB··on 0 A.D.: A free, open-source game of ancient warfare
That's almost entirely fixed with this release.

Since I help develop the game, I'm rather biased, but I think that it's as stable or more so than most triple-A titles released today.

JoshuaJB··on 0 A.D.: A free, open-source game of ancient warfare
The changelist make it sound rather underwhelming, but this release contains almost three years of work on a new pathfinder.
JoshuaJB··on Google to Fold Chrome Operating System into Android
This makes me sad. I used ChromeOS as my daily driver for over a year, and it worked beautifully. Always secure, always up to date. The available fast and elegant SSH and IRC clients combined with Google Drive alone covered most of my daily necessity.

I only stopped using ChromeOS because Microsoft hired me and gave me a computer that cost 5x as much. Google did an admirable job in optimizing for low-end hardware, but there is a point where you can only eek so much out of a dual-core ARM with 2Gb of RAM.

On the other hand, my android phone (which cost the same as the chromebook) regularly struggles to load the homescreen.

JoshuaJB··on 0 A.D. Alpha 15 - Osiris
I'm one of the developers for 0AD, and I have to say it's really not that hard to get started. I began checking out the source code and developing patches only about eight months ago (I didn't know /any/ C++ when I started, only some JS and Python), and in the mean time I'm gotten very familiar with the codebase and joined the official team. In fact, the multiplayer lobby in this release was primarily developed by myself.

Feel free to join us on #0ad or #0ad-dev on quakenet if you have any questions.
