gmisra··on Dr. Dre and Jimmy Iovine’s School for Innovation
Just a little history on what Dre and Jimmy consider "innovation": http://gizmodo.com/5981823/beat-by-dre-the-inside-story-of-h...
gmisra··on What Tesla owners are doing while you sleep
I suspect there are some HN readers with experience with how electrical grids work. Can somebody speak to this increased night load and presumably decrease in variance between daytime load and nighttime load. How would those changes impact grid operations? I'd guess that having a more consistent load is overall beneficial, but it's just a guess.
gmisra··on Ask HN: MTurk is no longer available to non-US companies. How are you coping?
Seconded. http://www.crowdflower.com/
gmisra··on How Long Do CDs Last? It Depends, But Definitely Not Forever
Back in the day (1999) I wrote a data processing and archiving pipeline for a research satellite, and I was surprised to discover the specificity of their data archival requirements. Off the top of my head, these were decision points: * Pretty much only used "gold" CDs, rated for longer storage. * CD write speed was restricted - higher write speeds caused more write failures * The total data payload was regulated (~600 MB I think), and one of the reasons why was because of the physical impact of human handling on the outermost areas of the disc. * Storage temperature was also regulated

But ultimately, the two main data storage strategies employed were: * Physical redundancy - six copies of everything, mailed out to six physically separate facilities every week. * No archiving "forever" - Archived data was (theoretically) to be restored to contemporary storage technology whenever there was a significant step change in storage technology. At the time, another member of the lab was working on restoring old Voyager data feeds, although I have no awareness of how common this actually was.

gmisra··on The Anti-Uber Way of Disrupting Transportation, Politely
FTA:

Like Uber, BlaBlaCar takes a cut of the fare, but crucially, prevents its drivers from trying to turn this into a job. In each of the countries it operates in, BlaBlaCar uses government guidelines on driving costs to set a cap on the fare. These calculations account for fuel costs, insurance and tax. The rule helps to avoid giving the impression that the app poses a challenge to cab drivers' livelihood.

"Because they don't make a profit, BlaBlaCar drivers aren't classed as professionals," says Nicolas Brusson, the co-founder and chief operating officer at BlaBlaCar. "They don't require special insurance or a special license."

gmisra··on Show HN: Gmail Thread Splitting
Apparently I am one of those haters. I guess "Is this really a thing people have trouble with?" is not a valid question, but I really don't understand when/where/why this thread-splitter feature would be useful, let alone useful enough to enough people to warrant extended time on the HN front page.

Can somebody (who won't presuppose my motivation or my opinion) answer my question?

gmisra··on Show HN: Gmail Thread Splitting
My favorite thread splitting plugin is "editing the subject field when replying". Is this really a thing that people have trouble with?
gmisra··on Amazon leaks Kindle Unlimited
Here in California, libraries are offering bigger selections of e-books on-line, which usually come with two restrictions: limited time of readability on your device, and limited number of copies available (and a waiting list to manage access). Amazon has historically appeared to support these library programs, presumably because they make kindles more appealing to the core "book purchasing" demographic as well.

In the near future I hope to have limited access to all these books for free, or unlimited access for $9.99 a month, and the ability to easily switch between the two consumption models. That, for me, would be an easy sell. This is pretty much how i consume Hulu - most of the time, I just want to watch recent episodes of the Daily Show and am satisfied with the free tier. And when I want to get after specific content, I bump up to the paid tier for a bit.

I don't understand why "some content is always free" model isn't more popular in the content world. If Netflix offered something like three free movies a month, I would never "cancel" my account. They would get better brand loyalty, better app lock-in, and lower customer churn. Instead, I get annoyed at the always-on subscription model and cycle between subscribed and unsubscribed.

Digitization of content changed distribution patterns, which changed pricing patterns, and the combination of both changed consumption patterns. It feels like there is a feedback loop where now it makes sense for pricing and user management (acquisition, retention) strategies to adapt once again, this time to changes in user behavior and consumption patterns.

gmisra··on Will Computers Ever Replace Teachers?
Discussion point: "We’re pretty good at testing the kinds of things that intelligent tutors can teach, but we’re not nearly as good at testing the kinds of things that the labor market increasingly rewards."
gmisra··on MIT And Dropbox Alums Launch Inbox, a Next-Generation Email Platform
The strongest statement you can make to this effect is to preferentially take _my_ money over VC money. Words on this particular subject have been reduced to having no value with most people.
gmisra··on Google Has Given HTTPS a Huge Boost
Are you in a position to request that these two videos are removed from the privileged access section of the GV Library? Definitely the top two videos I wanted to watch from there, and it seems like better security practices is a win for everybody. * http://www.gv.com/lib/security-for-startups * http://www.gv.com/lib/advanced-security-for-startups
gmisra··on Google Ventures Library
I am disappointed to see that the two security engineering videos are blocked by privileged access control. Improved overall internet security benefits everybody, and it's surprising that GV does not share that ethos.

If anybody from this project is reading here, are you abel to change that, or can you comment as to the motivations for how things are classified as public vs privileged?

gmisra··on Comcast is turning your Xfinity router into a public Wi-Fi hotspot
This has been in place in San Francisco for quite some time (at least a year, I believe, if not longer).

It seems like a great idea...for opening a giant MITM attack vector to anyone who chooses to use it.

gmisra··on The Cost of VC Money: Loss of Control
Honest question: is this idea really something people courting investment are unaware of:

"Investors are not in the same business you are"

And if so, why are those entrepreneurs surprised? What are their expectations?

gmisra··on How Wall Street recruits so many Ivy League grads
Arguably, the "pretty people" have been here for a few years now. But don't take my word for it: http://www.modernluxury.com/san-francisco/story/go-west-youn...
gmisra··on Apple Said to Be in Talks to Buy Beats for $3.2 Billion
The history of Beats is itself fascinating: http://gizmodo.com/5981823/beat-by-dre-the-inside-story-of-h...

gmisra··on RSS: What Not Dying Looks Like
I don't think very many people thought RSS "died", rather the _opportunity_ for RSS to become the dominant, cross-source publishing standard has died.

There used to be a world where all things on Twitter and Facebook were published to RSS feeds, drastically lowering the barriers to entry for experimenting with content consumption ideas, or cross-content aggregation, or personalization, etc.

There used to be a world where big, public technology players like Google and Firefox were helping on-board new users, and appeared to be making a long-term commitment to the technology. When Google Reader was a thing, the rate at which non-technical users in my personal network were starting to talk about RSS was astounding. And _everybody_ was thinking about whether or not RSS was a natural fit for their product/idea/platform/drone/toaster.

There was a moment in history where RSS was poised to become as ubiquitous as e-mail. But that opportunity was taken away, because the big tech companies either couldn't or wouldn't innovate on their business models, instead they're focused on the near-zero-sum game of user acquisition and retention.

A similar thing happened in the late 1990s with the major ISPs - AOL/Compuserve/Prodigy/etc actively encouraged you to only communicate in-network, e.g. how their chat clients initially worked. Unfortunately for them (but fortunately for us), their core identity system was based on the already standardized technology of e-mail. And eventually the ability of others to provide better/different experiences via e-mail (Eudora, Hotmail, Gmail, etc) changed how people viewed those networks.

This time around, the big tech companies are much more self-conscious regarding user base degradation, and the risks of having their core user experience compromised by out-of-network innovation. Consumers always lose this game.

gmisra··on I “Leaked” the story about the Biometric EarPods. But I’m not proud of it
I wouldn't go as far as to say they are "real" yet - they are still working on the prototype: https://www.kickstarter.com/projects/hellobragi/the-dash-wir...
gmisra··on Swarm: Foursquare's ambitious plan to split its app in two
This seems risky, but interesting. If the core foursquare app becomes focused on location discovery and exploration, they instantly become the most viable mobile competitor to Yelp, which is something I (and I think many people) would be interested in.

They're recognizing that the location browsing/discovery UX is fundamentally different than their social UX, and de-coupling them, while presumably using the same infrastructure under the hood. Hopefully, this will allow UI/UX development that diverges and serves each user group better.

I want a better, more usable location database on my phone, I would use it all the time. Yelp is unfortunately the default, I think because through crowd-sourcing data validation, they just have the most accurate listing of addresses, phone numbers, business hours, etc. But after that, Yelp is social features I don't care for, review writing that make me sad about humanity, and very likely bully-esque business practices (but I do like the pictures). Foursquare has the second best location DB that I've used, but historically the app has been more aggressive about pushing it's social features, which I do not want. So, I am curious and cautiously optimistic.

From the comments, it seems like what may be missing is the ability to check-in via the core foursquare app. This would be a problem if the life-tracking-but-not-social subset of users is as high as the comments suggest, but also may not be a problem if the "I was here" feature still exists in the core app and just has been messaged incorrectly.

gmisra··on Last Mile Logistics: Amazon vs. Fedex vs. Startups
What's interesting to me is that "last mile logistics" is essentially a commodity business. But there are two very common trends in the space that don't quite make sense to me:

1. Treating delivery drivers as "independent contractors". This seems to be a very common approach, with all kinds of plausible motivations (limiting liability, making variable demand handling easier, being able to call your service a "platform", keeping headcount cosmetics appealing for parent VCs, etc). Historically, delivery driving is a usually regulated and often unionized industry, so I wonder if this approach will scale. There are also often distortionary impact of these contractors on overall regulated wage industries (hint: your postmate probably does not make a living wage for the time spent being a postmate). Viewed from the lens of potential acquirers, if your "efficiencies" are based around not paying drivers in the same way they have been historically paid, that is not something I need to acquire.

2. User acquisition seems to be at a premium - quite a few of the delivery-on-demand businesses in San Francisco have been running generous new user and user referral discounts recently. It makes sense if their goal is to increase user rolls, but I find that most of these services have limited, if any, lock-in effects [a]. Obviously, in order to innovate on delivery-at-scale, companies must first achieve sufficient scale to be able to prove out new ideas. But, from my peanut gallery seat, the user acquisition strategies appear to be driven more by the "acquire users first and monetize later" strategy that happens when many similar VC companies are competing for the same users. Amazon/Google/etc don't tend to get excited about acquiring you for your user base, unless you can demonstrate high brand value or user loyalty, which seems particularly challenging in this industry.

So, my $0.02 is simply that platformization followed by paid user acquisition seems to be the template for this industry, and yet it does not make sense to me.

[a] I have heard recently of a local, "last mile" food delivery start-up that is approaching it's vendors with exclusive sales agreements. I am not sure how effective this well be - the business from whom I heard that also found the request completely ridiculous.

gmisra··on Am I evil, or is killing patents just plain fun?
Maybe we should consider whether software patents are necessary at all? There are disciplines where the core content is not itself patentable (or "intellectually protectable"), primarily because obviousness is hard to prove. The most accessible examples are food recipes and fashion designs - how do you demonstrate that a specific recipe has never been conceived of in the past? For disciplines that rely on the assembly of existing ideas, this actually seems like the rational thing to do.

Alternatively: can you think of any software patents that make sense to you?

gmisra··on Giving Away Our Recommendation Engine
Thanks for the clarification. I'm in agreement with your opinions regarding false promises of open source, and also that this is increasingly a problem. However, I don't think that actually applies here. Specifics:

1. Everything in this github repository (https://github.com/mortardata/mortar-recsys) appears to be truly open - it's just a bunch of pig scripts, some java UDF definitions, and some python management code. There doesn't appear to be any dependencies on proprietary MortarData anything. All the code is licensed under the Apache 2.0 license.

2. The blog post states: " You can run this code anywhere. It’s built on widely-adopted open source technologies—Hadoop, Pig, and Python. But we think you’ll want to use our platform."

gmisra··on Giving Away Our Recommendation Engine
The code is all released under the Apache 2.0 license, so calling such an action "disingenuous" is itself disingenuous, (imo).
gmisra··on The Joys And Ethics Of Insect Eating
I have tried these, and they are surprisingly delicious: http://www.exo.co/

They are labelled as "Made with cricket flour", but other than that you wouldn't know it was any different from the dozens of similar protein/nutritional bars out there.

They are a bit expensive, but I highly recommend getting the sampler pack at least once if you're at all curious about the taste, texture, etc: http://www.exo.co/products/pre-order-multi-pack

This is the other "major" brand of cricket-based protein bars: http://chapul.com/

gmisra··on American Chemical Society bans university after "spider-trap" is clicked
Seems like an easy way for a university-based "conscientious objector" to have this issue addressed would be to intentionally click on the spider trap link once a day?
gmisra··on Please read the comments
For those looking for more information as to how personally damaging "the comments" can be, I'll just leave this here:

http://www.psmag.com/navigation/health-and-behavior/women-ar...

To me, it seems simplistic and woefully inaccurate to characterize all internet communities with comments as sufficiently similar to even consider either approach as a blanket dogma.
