You can read more from me at my site: http://www.joshualyman.com

A technologist, founder, and current Googler, I've repeatedly taken products from inception to commercial success across sectors, from startups to Fortune 10 companies. My specialty lies in bridging the gap between business vision and technical execution, deeply engaging with code and who mentors teams. Beyond engineering, I bring a global perspective from living abroad for nine years and speaking fluent French.

ljoshua··on Apollo 11 Guidance Computer source code
These are great, well done.
ljoshua··on Forestry.io
Ooh, looks nice. I assume it's going to be a service though? Anyone know of similar style products out there that are self-hosted or open source? I have several scenarios where it would be great to tie together a static repo, an on-demand CMS like this, and the pushed final product, just like this looks like it will do.

Requested access though, looking forward to seeing more.

ljoshua··on The Real Product Market Fit
I strongly second this request. As a founder working through a v1 and currently thinking a great deal about product/market fit, it would be fantastic to hear more about this.
ljoshua··on There are now 234 pregnant women in the US with confirmed Zika virus
One important thing to note is that as of today's data, the CDC is not reporting any locally acquired cases [1] in the States (though that does not apply to US Territories). It is possible to infer, though certainly not conclusive, that the current pregnancy-related cases are either due to travel-related or sexual transmission, or possibly local if the pregnancy is in a Territory.

Stay safe everyone.

ljoshua··on With React Native it’s not all sugar and spice
Many of the points made in the article boil down to React Native still being a relatively new framework, and the team and community behind it iterating very quickly.

Sure there will be growing pains starting out, but the benefits that are coming from this new direction are, in my opinion, worth all the effort. I've written several apps utilizing React Native now, and love the efficiency boost it gives me.

ljoshua··on With React Native it’s not all sugar and spice
Sounds like a great use case of React Native where RN is specifically used for what it is designed for: the UI layer. I've done apps with both approaches (all RN or UI-only RN), and I'd love to read or see more about your approach.
ljoshua··on Self-host analytics for better privacy and accuracy
Can you elaborate a bit more?
ljoshua··on Siri creator shows off first public demo of Viv
That's pretty impressive!

Maybe this isn't as big a concern as I think, but the ease of these commercial demos relies on a crucial assumption: that I am nearly completely price insensitive. I'm not a cheapskate, but I don't usually purchase the first product a vendor puts up because there's usually something better and slightly less expensive if you put in an additional minute or two into the search. But with the demos given (ordering flowers, booking hotels, etc.) it's usually a sample of 2-3 different options, and from what I've seen, usually higher end items.

Will such assistants still maintain their usefulness when I don't have the monetary pleasure and freedom of just saying "Yes" to the first option offered?

ljoshua··on The Dyson Supersonic hair dryer [video]
Slightly OT, but how did they do the almost Matrix-style slow-mo pan and zooms in the videos? Array of cameras, rendering, some other technique? Very slick.
ljoshua··on Node.js ES2015/ES6 support
This is an important point. If your usage of these techniques is not on a hot critical path, I think there's much to gain by continuing to use them as the native optimizations continue to improve.
ljoshua··on Ask HN: Preferred VPS Providers?
I wasn't intending on making it a hunt for the cheapest and biggest and most oversold provider. I'm looking for folks who have had positive experiences with different providers. Comparing across numbers is easy, but first-hand experience is quite valuable.

Example: say someone is going to be bootstrapping a new venture, and need something in between a $5 DO droplet and a complex AWS setup. Maybe there are gems to be discovered, as DO once was.

ljoshua··on Linode Security Advisory
For me, because once you get beyond the $5 nano/free tier, things get expensive really quick.

For example, I run about 10 different sites off one Linode, but only one of them gets any substantial traffic. Still, in order to run that site, which works just fine on a $20/mo 2GB/2core unit on Linode, I'll push out about 150GB in outbound bandwidth a month, and require around 15-20GB in storage. Pricing that out on AWS, ignoring the free tier, I'm looking at at least $40/mo, so double the price.

These are hobby sites or side projects, so they are not necessarily mission critical, but it would be sad if they went down.

There's a serious benefit to getting a VPS when you're on the low end like that, where power and bandwidth per dollar are greatly maximized.

ljoshua··on Ask HN: How much equity should I ask for?
I love the analytical nature of this answer. Obviously some of it is based on experience, but do you have any resources you could point to for learning the math and principles behind this? Like a "Startup Equity Principles for Dummies" set of links?
ljoshua··on 10M former California students' SSNs/medical records/etc. being disclosed [pdf]
Odd. Seems like the concerns could be taken care of by a) not just giving them a straight copy of the database and therefore b) just giving them controlled access via user credentials (i.e., that particular user only gets access to certain sanitized views or certain tables).

Seems like the privacy concerns could be fairly straightforward to address by a competent DBA or two.

ljoshua··on Ask HN: What else do you read as regularly as Hacker News?
This is excellent, thanks for the recommendation.
ljoshua··on Ask HN: What else do you read as regularly as Hacker News?
Sorry, didn't mean just visited links. I want unvisited (but seen) links to be treated differently.

Example: I visit once, scan 30 links, click 2, and leave. Come back 2 hours later, there are 5 new links, 5 have dropped off, and my attention is drawn to just the five new links, regardless of whether I visited the other 25 or not.

ljoshua··on Ask HN: What else do you read as regularly as Hacker News?
Side question: does anyone know of a browser extension or anything that would hide/gray out HN headlines that I've already seen on previous visits so I know only what stories are actually new on the front page? Would make scanning quicker.
ljoshua··on How Wired Is Going to Handle Ad Blocking
Ah, very nice. The pricing is higher than I would have expected (€0.25/avg), though I wonder what ends up being sustainable.
ljoshua··on How Wired Is Going to Handle Ad Blocking
That could work as well. Some sort of normalization would need to occur such that someone visiting 1,000 sites on a $5/mo budget would compare favorably against someone visiting 10 on the same budget. But that would certainly further reduce inaction.

I think some sort of feedback would be important, at least in the beginning, so that people understand how this magic pile of money is being treated.

Who wants to give dexterdog a ton of money to go do this? :)

ljoshua··on How Wired Is Going to Handle Ad Blocking
As has been mentioned elsewhere, my exact problem with this/Forbes approach/elsewhere is that there is no way that I want to suddenly start managing several new monthly subscriptions for all these outlets.

I enjoy Wired, but the thought of adding yet another subscription to my monthly credit card statement is too great a cognitive load for me to want to make the jump. Also, if you were to subscribe to the dead tree version, you get 6 months of dead tree + digital + a physical object (battery) for $5 that comparing it to $4/mo for digital only feels cheap.

I don't mind paying a small amount for reading the occasional article, but I don't want to manage a ton of new subscriptions.

Suggested Solution:

Now micropayments have never taken off for much the same reason, but what if I funded one general "content publishers" account with the equivalent of that $3.99/mo? When I get to a paywalled/ad-block unfriendly site, I could choose to fund that particular article using a micropayment from my general fund. I would have only one subscription to manage, would feel good about contributing to content I felt was quality, and people would get paid.

Of course, this takes content publisher buy-in, but if they're already in the process of trying new things, how about it? Feels a little similar to the failed Google Contributor project, but with more direct decision making. Can someone go and build a great business out of this for me?

ljoshua··on [dead]
Hey guys, the portfolio of templates looks nice, but translation needs some work. Most every sentence I could read (including the HN title here) is very awkward sounding to a native English speaker. Makes me hesitant to sign up for anything for fear that I just won't know what I'm getting in to.
ljoshua··on DigitalOcean lost our server
I hadn't heard of the backup providers mentioned in the article. Does anyone have experience with those or with other recommended solutions?

I can re-implement the infrastructure of my VMs fairly easily (thank you Ansible), but backing up content outside of the provider's built-in options is something I haven't played with yet, and would obviously be the crucial piece.

ljoshua··on Show HN: Space Shooter in QBasic
Oh man, QBasic was the first programming language I ever encountered and started playing around--what great times!

At the time (I was probably 11 or so) I knew that it was important to learn to write serious stuff, and knew that an operating system was probably "serious stuff," and so I thought it might be a good learning experiment to write an operating system in QBasic. Needless to say I was missing a few links in how "serious stuff" was written back then, but it sure was a fun intro!

ljoshua··on Chrome Cleanup Tool
Or DaisyDisk, I love DaisyDisk.
ljoshua··on Jade template language forced to rename to Pug
Great example of a community coming together to just get stuff done. Benefits of open source right there.
ljoshua··on Google Genomics: store, process, explore and share genomic data
No, it's a Business Associate Agreement, part of HIPAA. (See a sample here: http://www.hhs.gov/hipaa/for-professionals/covered-entities/...)

Basically an agreement between organizations that there is an understanding that PHI (protected health information) is at stake and that both parties are aware of their obligations to protect it.

ljoshua··on Tesla Powerwall: Crunching the Numbers for Australia
Interesting to see the different power usage and electricity rates for a different part of the globe. Here in the Houston, TX area we used 848 kWh in a 30 day winter period for a mid-sized home, which is as much as the article states the household used in a 95 day period. During the summer, when my old AC unit is running like crazy, we'll use ~1800 kWh, and our rate is an average of $0.102 USD, which is around 60% of the top rate from the article.

A Powerwall unit still wouldn't make sense for us, but this is rev 1, and so in a couple of generations we could be looking at something that actually could be impactful.

ljoshua··on Adsuck – a small DNS server that spoofs blacklisted addresses
Another way to accomplish it if you've got a spare computer (even something like a Raspberry Pi) is to configure it as a DNS server and then use your stock router firmware, if it supports it, to point DNS servers to that computer's local IP. So one device in your home or network would then become the local resolver.

Awesome, thanks!

Two specific examples: a Victoria's Secret ad, and one for a movie that was far too scary for young children to be seeing.
