I believe that PageRank works off of an index of all webpages and ranking is primarily based on the number of links to a particular url. It seems likely that given the number of articles released in the last year about the fundraising efforts of the company, compared to the likely small number of webpages that need to link to the wiki page for caviar (lol), it gets ranked higher, accordingly.

However, I suppose if I am to google caviar then maybe case sensitivity should be included in Google's rankings.

The shape of the distribution affects the value of the introvert/extrovert distinction pretty strongly, though. If it's strongly bimodal (so a random extrovert is very different from a random introvert), then it says a lot, while if it's unimodal with a small variance (so a random extrovert is only a little more extroverted than a random introvert) it doesn't say much.
Pretty easy, you can ace without knowing all the languages/APIs used, just follow the usual code smells.
If I understand correctly from reading the man page[1], unlike Puppet there's no server.

You just run a command line tool on a node to inspect or create a "system description". You can then export and deploy a description to create repeatable systems. In this regard I think it's similar to what Blueprint[2] does (or did I guess since Blueprint seems dead now). So it's a lot more lightweight tool and has many less features than Puppet, certainly.

Another cool thing is you can use Machinery to build images and deploy to Openstack. Where I work I spent a pretty long time building similar tooling for Xenserver. Sure would have been nice to have just been able to say "oh there's a thing for that". I'm excited to try this tool out and see what it does.

I think Machinery only works on SLES and opensuse right now. I didn't see any mention of other distros.

We've never held back anything from Ansible, really. Rather, Tower is more of a product on top that provides some extra enterprise features that most of our user bases don't need (but they should try it, because they might!).

I think if you see things like Windows being part of Ansible proper, it's clear we're not holding that back. But there are also tools the OSS community can't build easily, things that involve coordination around database schemas and (ick!) status meetings and UX mockups.

Yes, communities can build them, but occasionally, just occasionally, companies can build them better. And this is one of those cases. Our business model basically funds Ansible and also makes Tower significantly more capable that way, and it only becomes something you need when you can afford it. And it's not so much because we're a company, because I've got tons of awesome folks working in 100% full time, and that's a lot of power to build good stuff. Most likely your company employs a few folks as well :)

So on the "open core" comment, Ansible won't, for instance, ever have proprietary modules. That's something we said we don't do. Ever.

As for Tower, the small guy isn't going to need it yet. He's probably ok with pure Jenkins fronting the show. The big guy probably needs it and a super-well-tested environment and a guy to call when it has issues.

I don't know anything about other communities you've been a part of, but I think our track record shows what goes where
and people are comfortable with it. Ansible isn't open core. It's the real deal. We take that seriously.

Yet, I think the general assumption that all software has to be purely 100% open is flawed, but that in general, open source communities can build some things in GREAT fantastic ways, and certain layers do benefit from being free software. But companies need to exist. Including yours! (Though I do love me some Uber).

Anyway, ansible-pull is indeed an option if you wanted to go that wrote, or even doing image builds with Packer. Both popular options for immutable systems and/or autoscaling, sans commercial bits.

But is commercial software dirty? Heck no. Ask any SaaS company :)
> In this specific case I submitted a bug and was told the bug wasn't valid and it was closed.

Maybe that is what you might have said in your blog post instead of a snarky comment. Remember, many people in open source are not from the upper middle class United States / West Coast and will likely not pick up on clever passive aggressive jabs. I completely understand that they are great for being able to deny any accountability for your attacks, but it generally leads to a lot of misunderstanding. Especially from those who do not speak English as their first language.

I really don't mean this to jump on you, but hopefully you might take it as some advice when dealing with large distributed projects that passive aggressive snark, I would guess, ends up actually going over the head of 50% or more of the people.
I feel like the entire configruation management movement has passed me by. I still don't understand what value there is in chef/puppet/salt/ansible/docker vs bash or even Perl for that matter. Someone care to set me straight?

> Basically the problem with the military is that they won't (or can't) pay enough to retain any of the talent they have and are unwilling to compensate for the low salary by changing the "culture" they've developed over the last century.

These are all problems that are slowly working their way up the policy chains. E.g. RAND has put out a very good study on all this, http://www.rand.org/pubs/research_reports/RR430.html that discusses the challenges with public sector/military hiring (and retention).

It may yet have to come down to putting the effort heavily on the Reserves though, because for all the other things the military can change, I don't see culture as being one of them. Even the legendarily free-wheeling communities like submarines and fighter aviation deal with red tape and subsuming egos to the team.

I might have worded it better, but pandemics are actually one of those areas that people get the risks wrong for the opposite reason than usual. While pandemics are considered low frequency, high risk events and so over-worried about, they are actually relatively frequent events on a historical time scale and are not worried about as much as they should be. They are really more in the car crash category not the stuck by lightning category, but we get complacent because a big one has not happened in living memory (unless you count HIV).

I am using a Xiaomi “Redmi” (紅米) in Taiwan. I was blown away by the interface they cooked up — it’s the slickest Android UI I have seen so far. It definitely takes cues from Apple, but I also feel that Xiaomi has done some solid design work of their own — for instance, the icons for basic functions and system apps are original and quite effective.

But in other areas it doesn’t come close to Apple. The hardware looks and feels more like some of the midrange LG phones I’ve used in the past, and compares poorly not only to the iPhone but also recent Samsung and HTC phones. I’ve also discovered a lot of buggy behavior that I’ve never seen in any Android device, including an inability to delete photos (the dialog reports I don’t have permission) or apply system updates.
Fixing the indentation would also make the Python code readable. (For those who aren't aware, whitespace is significant in Python.)
When you're managing more than a handful of servers, you very quickly start wanting to be able to run the same command on multiple machines - "upgrade all my API boxes to the not-vulnerable nginx", for instance, or "push this binary out to all my database servers". These sorts of services make that straightforward, and generally provide a large library of prewritten modules to do moderately-complicated things without having to write a lot of boilerplate or read somebody else's Bash scripts or Perl.
Hm, interesting. Hadn't heard of either of these. On the one hand, they're playing a huge uphill battle and would need to employ thousands of couriers if they want to serve just America's major cities. On the other hand, they could completely rewire the food delivery business. I'm not sure it can work. Restaurants can hire minimum wage or below family members or illegals to deliver as an essentially free service. They live off of tips. Caviar would have to charge a significant premium to stay in business.
Also: his book "he Master Switch" is a good read with lots of good background material about how very large businesses try to control technology and markets.
A similar effect can be noticed on sections of roads with dedicated overtaking lanes. Cars that are travelling below the speed limit for long stretches of road (and can't be overtaken due to the road), tend to speed up to the actual speed limit when an overtaking lane comes along - likely due to the more open road, they feel safer driving faster, etc.

This makes it more difficult for all the (often frustrated) drivers behind to pass the slow car when the time comes, often meaning they put on the afterburners and exceed the speed limit to overtake - which could lead to more accidents, especially if they are trying to squeeze past at the end of the overtaking section, if it is quite short, or there are many cars stuck behind as 'prisoners'.
> I'm curious if reservists deemed to have critical skills would be called upon to act beyond an amount comfortable for them, considering that they typically already have full-time day jobs as mentioned in the article.

Yes, that is certainly possible. The whole "1 weekend a month, 2 week a year" thing died with the World Trade Center. While Reserve units certainly try to maximize flexibility to try from interfering with their reservists work balance, getting called up unexpectedly (even for a period of months) is not that unusual if/when shit hits the fan somewhere.
I don't understand how the military cannot afford to compete with the private sector. This is where wars will be won now (or soon). It's pretty important to defend ourselves. And we have trillions of dollars...
I agree. I think the patent system is bonkers, and these trolls are awful, but in general it seems pretty reasonable to only sue a party for damages when that party can feasibly pay the damages.

I wonder how the economics of the cloud industry will eventually play out. Right now, it's enormously profitable, because Amazon is the clear market leader and there're some fairly significant switching costs.

However, building out the cloud infrastructure is a side-effect of being any Internet business that achieves reasonable scale. And once you do that, it's both relatively inexpensive and quite profitable to enter the IaaS market and resell some of that additional computing capacity to other smaller firms. Cloud computing is almost totally undifferentiated; you're selling basic computing resources (CPU, RAM, disk) for money.

My hunch is that cloud is going to become like the airline industry. An oligopoly with periodic price wars. It has the same "high fixed cost, low marginal cost" economics as airlines, the same need for some baseline technical knowledge but not enough that you can differentiate on product quality, and the same price-sensitivity. It's possible that the switching costs of migrating your data between cloud providers might put a barrier on competition and preserve some profit margins, but I suspect that any well-used service will be able to migrate their data out for a small fraction of their monthly bandwidth costs.

The airline industry is wonderfully beneficial to consumers, but it's been a dud for investors and operators over its 100-year history.

> All ML is density estimation using a parametric probability distribution.

Umm is there a typo there ? Otherwise it is so wrong that I cannot even begin to pick the flaws.

In fact the key revolutionary idea in classification theory, courtesy Vapnik, was that one needn't estimate the density at all.

I cannot over-emphasize the revolutionary part, prior to Vapnik, that over-arching consensus was that one should try to learn the the density and then threshold it to obtain the classifier. The motivation for this is the result that the thresholded conditional probability is the optimal classifier for a {0,1} loss.

What Vapnik showed was that it is better to learn the classifier directly (he called it structural risk minimization, SRM, for short), without any parametric assumptions whatsoever. The main reasoning is that density estimation is freaking hard, and depending on a freaking hard task as a pre-requisite is backwards. Learning to classify is actually easier than learning densities. It was one of those paradigm shifts that come to a field only once in a while.

Even if we let SRM be, even in traditional statistics there have been methods as old as time that do not assume any parametric model. Those into non-parametric statistics (I am not one) would be very upset with your claim :) The problem with parametric models is that you almost never know the parametric family. You can of course test, but how many would you test, there are infinite number of such families. Non-parametric methods dont make parametric assumptions, (they do make some and considerably weaker assumptions. Assumptions are necessary for learning). The drawback is that they are more expensive, similarly if you happen to know the correct form of the family parametric model would be hard to beat.

> Basically, if the rules tilt towards the Uber model there is no reason for Kim to exist. He's a middle man in a business that is going the opposite direction.

Not at all. Maybe though, he's a local middle-man in a business which is going toward global middle men.

After all, Uber and Lyft are nothing if not middle men.
Brain-wise, I think all nations have the possibility to have some top achievers at any given field. It comes easier when the population is larger. The human beings' organizations come with so many system differences such as ways to cooperate, education system. I recommend to think from a system's perspective. If copy is a way to catch up and serve as the basis for evolving one‘s own true strengths (well, true strength here makes the difference), it's definitely a good thing. If copy only brings almost brain-dead repetition, even others can not stop it, it will implode in the end.

Sorry to reply with such an abstract content. There are just too many things in my mind to say. So I try to provide some general ideas instead of be very specific. BTW, I do not like taking culture as a dimension of answer, since it's too general and culture is the symptom of an organization. When we talk about culture, we just has to accept the symptom of one organization as is. Hence, it brings us not much information. But it is extremely difficult to have some nice insights for culture we don't have enough context with.

I'm not a developer, but I do have the technical knowledge and understanding to work and communicate with developers.

I've been working in the product group (directly with the product manager) for a SaaS product for three years. The company was recently acquired, and now I'm interested in expanding my skillset through a product development role with a smaller team.
Interesting that DeSoto fails to mention why people seek out Uber. Kim seems to be focused on the medallions pricing structure completely ignoring user advantages such as ease of access through the app, reliable service, quality, etc, etc.

If cab companies don't realize that new services beat them to the punch in many areas besides pricing they won't survive.
Possibly. I think a lot of it depends on the people you're trying it with.

It's probably a safe assumption that the peer group I tried it with then (high school) reacted quite a bit differently than my current peer group would (largely very intelligent coworkers).
I guess you're really not into those, then. Personally, I don't find them all that bad. In fact, if upkeep at a place is lacking, like e.g. especially in a park or campsite, they're much better.

Anyway, I'm done discussing toilets :-)
It seems to me more like "estimating threats" than "knowing your place in a hierarchy."

Unfortunately, it was not the same: in the picture [1], the left is the one I'd purchased this time, and the right is the one I'd destroyed.

The one you destroyed has a single Samsung 128Gbit TLC flash; the one you bought has a pair of Micron 64Gbit MLC. I'd say the latter is almost certainly better from a reliability perspective, and probably even cost more to manufacture.

This is the sort of question that needs a blog post to answer, IMO.

I have not had enough time with any of these tools to speak to the pretty, but I can speak to the ugly. The chief issues with these tools on Windows are package management, overall speed, and community focus on not-Windows.

Package management is the worst, IMO, and it stems from Windows and the majority of it's 'software universe' being commercial. Software is expected to install on many editions of Windows; it is not common to see edition-specific packages for anything not otherwise edition-specific. Software can be packaged and installed many different ways, some of which do not support unattended installation. It's not always clear whether a package is installed at all. It's usually difficult to repackage software that doesn't work the way you want it to, and even if it's easy to do you probably can't redistribute the result.

So yeah, in general, package management is the ugly.
I also think that's not always a dead end. There is also an opportunity to grow. For instance, I know Uber exists, but since I only take taxi occasionally I don't own an Uber account.

In NY, the Chinese and the Korean community have their own network knowing how to reach the Chinese/Korean-speaking car service and shuttle service. Uber or alike cannot beat this system. These locale-specific service operate with just telephone. Very school but effective! No app, no Internet access. Pretty reliable and cheap.

So all he need to do is to find a community to target at and find drivers willing to join him.
Nicely said. It might just be my USA-centric views on poverty, but I find the idea of turning homelessness into a story with a contributed artistic element--typography--refreshing in a sense. Maybe it's just because all the people are smiling in their headshots :\

I realize the charity element to it might obfuscate the idea of it being "art," but I think it strikes an interesting balance between the two. Compare that to artists who document homelessness and use their art as a kind of charity, hoping to draw awareness to the issue: http://www.dailymail.co.uk/news/article-2090360/Lee-Jeffries...
