Ubers board wants Expedia CEO Dara Khosrowshahi to be its next CEO recode.net

This is the guy who made a huge tactical mistake when Booking.com was challenging Expedia by choosing to stick to merchant model (i.e., buying inventory) as Booking went for the agency model (i.e., lead gen).

Expedia has moved to an agency model since but the damage was done. Booking managed to get far more inventory, capitalise on more search/PPC traffic and blow past Expedia.

Wonder if he's going to make a similar kind of mistake and misread the transportation market.

Props to a fellow originally Iranian though :-)

CEOs often lead on partnerships and strategy. I wonder what connections in travel this new CEO is going to leverage and how that will affect the uber operations in the short term, and the ridesharing product itself in the long term.

airline points on uber? (these are surprisingly sticky with consumers)

uber exclusivity deals or packages at hotels?

I expect to see more bundles of things with uber involved.

I wonder how much Uber will have to give him. He's already running a $22b company and was granted $90m in options less than two years ago. My guess: $500m minimum at a ~$30b valuation.

Looks like Recode has only had time to update the title to reflect the Expedia decision. The story was previously about how "Uber's board says it voted, but will not divulge its new CEO until employees know".

This new guy is an outspoken trump critic.

Meg is a republican, and ran as one for california governor

#deleteUber was started and accelerated partially by assumed associations between Uber and Trump

I wonder if the politics had any influence in the decision to pick him over meg.

Here's another story/fact that should be included.

There's a species of octopi that live in groups. On nights with bright moon, predators can identify them because they cast a shadow. They have evolved an organ to intake particular bacteria that use what's called quorum sensing to detect when there's enough of them around. When the organ is full of these bacteria, the bacteria glow and therefore stop the shadow of the octopi. It's a great example of symbiosis, more specifically mutualism of two species. The octopi get saved and the bacteria get a safe place to live.

"It was made to aid in discussions about missile development, since the technical nature of honest-to-god 'rocket science' can make it rather impenetrable from the perspective of laymen, yet many of the fundamental questions are key to local understanding of geopolitical questions (e.g., 'could North Korea hit my city with their latest missile?')."

And in case you're curious, here are the latest figures I could dig up on N. Korea's launch capabilities. Caveat emptor!

Range: 10,000 km (Hwasong-14 aka KN-20 test successes indicate >6690km range, though the missile appears to break up on reentry)

Circular Error Probable: ? Poor. Could not hit a city, especially since it breaks up before hitting the target.

Yield: 7-8 kilotons according to seismic estimates.

Why VOID? Why not something else?

aaron-lebo 7 minutes ago 0 replies      
Good to see void here. Super underrated.

If you like minimal, BSD-ish design decisions in a Linux distro, Void's it. Also the easiest install outside of BSDs. The latest packages are usually available (nim for example is a one line install) because it's rolling release, it's like arch without the crazy annoying setup.

The only reason it's not a daily driver for me is the gaming support isn't there like Ubuntu or arch, but outside of that it is one of the best distros out there, desktop or server.

There's one complication that I've seen in another watch and that puzzles me a lot.

On its back this watch has sunrise/sunset times. These times are derived from a so-called sunrise equation [1] which depends on the day of the year and the latitude, and is expressed via trigonometry functions.

I can see how this can be translated into some sort of irregularly shaped gear(s) if there were a single variable (the day of the year), but I have no idea how one could also allow for different latitudes.

Does anyone know or care to guess?

Excuse me if I'm ignorant; I get that it's a complicated watch but how are complications a countable concept? They list "57 complications". If I just added a 6 gears to the mechanism that do nothing, does that make it 63 complications? If I change the circle to a complicated shape with 25 vertices, is that counted as one complication or 25 complications upon the simplicity of the circle? If I tell time in binary, how do you count the added complexity?

What makes a good REPL? vvvvalvalval.github.io

"Finally, not all programs need be fully automated - sometimes the middle ground between manual and automated is exactly what you want. For instance, a REPL is a great environment to run ad hoc queries to your database, or perform ad hoc data analysis, while leveraging all of the automated code you have already written for your project"

This is exactly why I love Python. My Django webapp gets features (DB reports, external API pushes, etc) added as the client's budget allows, and before they are I'll often do them manually. Given that the UI for a new feature is usually the most work, it's been working well.

So the process usually goes: REPL/Django shell -> Django management command -> End-user facing feature. I'll grab what I did the first time in the Django shell, and put it into model logic plus a tentative management command. Then the next time I have to do the task I'll make sure the command works properly. And then when the budget allows I'll add access via the UI.

Ninja edit: I forgot to mention that `import ipdb; ipdb.set_trace()` is invaluable to get to the point in the HTTP response code where you can start adding new stuff or diagnose errors directly.

With fast compiling languages a unit test is not for off from being a REPL. In Java I use JUnit as a REPL.

Actually I prefer unit tests over a REPL the same reason I prefer bash scripts over one liners or SQL scripts instead of typing into the interpreter... I don't like the ephemeral nature of REPLs.

Also with true REPLs unlike the debug unit test approach I mention with Java you really need the language to be dynamic. I'm not entirely sure why but static type languages are not very good at allowing code modification while running (I mean I have ideas but I don't know precisely if there is an actual theoretical limitation).

I guess I prefer static analysis over the complete ability to modify the code base while running.

Only add my 2 cents because the article doesn't mention any negatives to REPLs.

Many moons ago, I was forced to use a computer. I pretty much hated them, back then. Anyhow, I had to learn BASIC. To do so, I got a bunch of books and my first program was a rehash of a skiing game. I called it Ski Downhill Faster. (Naming things is not my fort.)

It made the rounds at the university and was improved by others who were more adept than I. It was a bit of an informal open source, I guess.

I was actually talking about this recently and lamenting the lost data. It's unfortunate that so many little things weren't archived. I highly doubt that a copy exists anywhere.

I had a close call this summer whitewater rafting on the Upper Animas River in Colorado and it has caused me to re-think every serious risk I take and has changed me in a big way. I was participating in a multi-day trip run by one of the local guiding outfits through the Upper section of the river, a much more difficult and serious undertaking than the Lower Animas, which is frequently run by average day-tripping tourists. We were on the No Name Rapid [1] and our boat capsized at the entrance to the rapid. I was stuck below the boat, my body somehow entangled in rigging, and was dragged underwater for some distance through a very fierce class V rapid. I was finally able to free myself enough to get my mouth above water and breathe, close to drowning. I managed to fully free myself and swam to shore at the first opportunity. When I made it, I kissed the ground and promised that I would never needlessly risk my life in the pursuit of adrenaline again. I cried like a baby when I returned home that evening and held my kids and wife again.

Prior to this trip, I had done many adventurous and dangerous activities: rock climbing, ice climbing, lots of mountaineering, off-road driving, backcountry skiing... it really brings it all into perspective when you have a close call. All of that adrenaline-chasing just seems completely ridiculous to me now.

I've seen this mentioned before, it seems to be the main point.

> Most beginners who die appear to be making variations of the exact same error, according to Webb. They jump off a cliff, get flying, and for some reason there's just this human reaction to try to hug the air like a big, gigantic beach ball, he explains. By hugging air you feel as if you're creating or catching more lift than you actually are. What ends up happening is your suit can only grab so much air, and it starts to stall. When it starts to stall, it loses lift, starts to drag, and then, splat.

The major thing overlooked here is mindset. After 14 years in the military and experience with several armed conflicts and humanitarian disasters, I have seen that pretty much all your plans and preparation will go out the window, so you need to learn to move adapt and improvise.

If you're going to survive any contingency scenario you need to be resilient, excruciatingly innovative and mentally tough. Think more like MacGyver and less like Dr Strangelove.

Be minimal, learn how to forage and scavenge, learn how to blend in and get along and take nothing for granted.

The most successful trait I've seen in survivors it's to know when to stay put and when to move. Whether it's hiding from a mob or a bear, or finding a different county or state to go to.

Take risk when necessary but not unnecessarily.

Again, having the right mindset, through intentional training is the key. There are all kinds of survival schools and the best ones will teach you this. I suggest adventure traveling as a start. That means you go someplace with no plans and the most minimal of supplies.

Edit to add: The key problem with most prepper folks and this article is that they take an approach of "alone and unafraid." Things like stocking up for months and having all kinds of weapons. In practice this is just a great way to get your cache raided by a group of scavengers. In reality you need to find or create a small community of survival minded people that can work together successfully over a long period with a variety of skills. As humans we need groups for survival, so the best bet in a crisis is to build a resilient flexible community until things settle down.

I've been in a number of major natural disasters at this point. Fukushima, Ike, Colorado's 2013 floods. I've also been in two shooting incidents (where fortunately only the shooter was hurt). My point is, I've been lucky so far because none of these posed a major problem for me. I made it out with manageable inconvenience.

However, I can only get lucky like that so many times.

So now I keep the following at home:

* 5 gallons drinking water

* Canned food for a week

* First aid kit

* Matches, lighter, Sterno cans

* Solar USB charger

* Many flashlights with spare batteries, plus a battery-powered lantern

* Hand-crank radio

* Solid liquor collection ;)

* Equipment to make a fresh cup of coffee with no electricity (Sterno, hand-crank coffee grinder, French press)

* A big bucket for, well, sanitation

I've also got my camping supplies, which includes a Coleman stove and a few small propane canisters. Having been in a few floods I will also never live in a ground-floor apartment. I also keep all this stuff boxed up in plastic crates, so if I needed to evacuate I could load up my car with all this gear in about 20 minutes and be on my way. My goal is to be able to survive a week trapped in my apartment with no utilities, or living out of my car for the same amount of time.

I bike to work and in my pannier I keep a Leatherman multitool, pocket knife, latex gloves (mostly for fixing my bike chain, but also useful in other emergencies), 3M N99 mask, flashlight, poncho, a garbage bag and a small thing of duct tape. In most of the kinds of disasters that hit Colorado, I would be able to get home, either walking or by bike. I only live about three miles from work.

A 10 AM Bay Area earthquake is the highest plausibility * severity event you're likely to experience around here on a day to day basis - leaving some people with a 25 mile commute back to a structure that might or might not be standing, intermittent at best communications, and potentially impassible roads.

IMO if you don't have a case of water, a road map, and a change of walking-around clothes in your car around here, you're asking for smiting. Fortunately that's about $10 in total, and you can drink the water even if there's not an earthquake.

Additionally, near everything that would be handy in case of an earthquake (gloves, pry bar, basic trauma supplies, etc) is useful in case of a car crash, which actually is far more likely.

That's because for all the talk about Google its network engineering drives networks like a buzzed 19 year old drives his fathers Porsche.

Google does not believe in BGP filtering. They just don't. When someone brings up a BGP peering with Google that someone announces any prefixes to Google without first registering it. When asked "Huh? How do you ensure that I do not announce someone else's address space to you" Google's response becomes something akin to "We are Google, we have a very complicated system that prevents that from happening. It will detect the issue and address it automatically. We would build your filter lists based on those announcements" At the same time, the same people say that prefixes advertised to Google over PNIs take hours to propagate across the entire Google network.

BGP filtering of prefixes to the address space registered to the peer is a basic hygiene, something that Google simply does not believe it has to do.

A really interesting read. I agree BGP leaks are a great risk to instability, but that could be said about any glitches that affect major backbones like NTT and Google (not a backbone but it's so well connected...). BGP Routing issues happened numerously, and will likely continue. Last year with Telia too had 4 or 5 "glitches" as they upgraded their network. [1] I talked to them about it and the mitigation is always the same, be more careful, peer review, additional filters, etc.

Since each ISP implements BGP/Routing Tables/Topology in their own way, I'm not sure what you would do about this, other than choosing your peers carefully and filter any crazy route changes.

What is BGP?

> necessity to have filters on both sides of an EBGP session. In this case it appears Verizon had little or no filters, and accepted most if not all BGP announcements from Google which lead to widespread service disruptions. At the minimum Verizon should probably have a maximum-prefix limit on their side and perhaps some as-path filters which would have prevented the wide spread impact.

Wow that's just stupid on Verizon's part given the magnitude of potential impacts.

Every time I see basic internet infrastructure experiencing issues, my default is to think about who is testing a new cyberweapon or censorship mechanism. BGP has been known as trust-reliant for a while.

This is absurd. If these patents are ever enforced, I hope the cannabis industry doesn't stop until they've destroyed this company, the people who run it, and anyone who associates with them. In a court of law or otherwise.

I went ahead and looked up these patents. This one looks particularly bad:


This basically grants them a patent on every single cannabis plant which has >3% THC and CBD, and which Myrcene is not the dominant terpine. Can anyone who knows their bud say which strains this could be applied to?

Also, the specification on this is HUGE. This represents a large investment; they're going to filing continuations on this until the cows come home.

EDIT: I found this website: http://analytical360.com/

This lists a number of strains that could potentially read on this, such as Gorilla Glue: http://analytical360.com/m/archived/261533

Headline of this evening's South China Morning Post: How China Quietly Grew Into a Cannabis Superpower


Article states that more than half of the 600 patents related to cannabis are held in China. Unclear if they relate to industrial hemp or medicinal uses.

The race to get coveted FDA approval is even more heated. If GW Pharmaceuticals' stock price is any indication, it may be first out the gate with its CBD-based epilepsy treatment, Epidiolex.

A powerful drug derived from marijuana is on the cusp of federal approval

Ah, patents again. Who wants free markets when you can have a winner-take-all system based on government-granted monopolies.

Its amazing that we at all allow the possibility of a field brimming with promise, that resulted in so much oppression to poor minorites, to be suddenly, just as the moment turned towards freedom, captured and terms dictated by a small group of rich people when others have bled, been deprived of their freedom, and were there first.

What is the current state of Case Law with regard to DNA in the US? And how, if at all, would this carry over to the genetics of plants?

How much of a natural product is it safe to say is patentable? And how much of the patent has to depend on things like "processes of manufacturing", etc?

What annoys me is I was trying to tell people this was were this was headed. I suspect Monsanto is the big player or affiliated with whoever it is.

I once had an economics professor who insisted the bigger hurdle to marijuana legalization was monetizing it. It's a quite unique cash crop in that it only takes a small area and small amout of labor to produce large supply. His words, paraphrased: "You can grow enough marijuana in your basement to meet the demands of your whole neighborhood! And it's a difficult thing to patent to use IP ownership as a revenue model..."

Looks like BioTech Institute LLC (and I'm sure lots of others) are trying to address the second point.

It's rather sad that the only thing a trained journalist can find in 150 letters written by a hero of the first order is I would not like the journey, and I detest America. - a remark made once by him.

I'd like these letters to be analysed by people who could make some real sense of them and put them into a decent context. Finding a throwaway remark that many have made on the spur of the moment and headlining it is a bit crass.

I personally know vik, knew of the project, and so was so excited to see this article here by coincidence. He's personally investing great effort to rescue music that otherwise wouldnt be heard. Super recommend his other albums (one is like a Haitian Buena Vista).
