Outbound traffic (placing a call) is entirely separate from the inbound path. This is similar, in a way, to IP. You can send a packet with any source IP from basically anywhere on the Internet. The difference is that with IP, any return packets are routed separately, to the source IP. With a call, return voice just goes along the established channel. Each provider along the way will know who they received the call from, but cannot verify that the number belongs to them.

This is by design and used in many cases. Call forwarding, for instance. Or even just the basic case of using multiple providers to route outbound calls. Some might be cheaper than others, so you need to select on a call by call basis. Also, think of international calls. How is Idaho Telco XYZ supposed to be able to verify that this call from Zambia really belongs to ZambiaCom XYZ? And vice versa.

Also note that there's simply no requirement to even having a number. You could just be placing outbound calls (like SkypeOut). Or no one to one mapping: an office sharing one number for outbound calls, or a single telemarketer changing numbers call by call as they dial for different customers.

Have you read Bad Pharma by Ben Goldacre? One of the more interesting findings discussed in the book is that doctors were convinced they were personally not affected by drug company PR/goodies (3 day conferences in Bahamas, etc) but they were all worried that their colleagues were.

It's an excellent book and I highly recommend it.
It was an exchange server, which is a bit irrelevant to its security, were it maintained correctly. One issue is that it wasn't just an Exchange server, it was a 2003 version of the software and seemingly didn't have very good security protocols surrounding it.

This is really long, but my sampling of 3 talks were all excellent.

Here's a link to the Foundations of Data Science course that Michael Jordan discussed in his talk: http://data8.org/ [quote: [Statistics] is a 300 year old field that got encrusted; it got hyper-mathematical [...]. You get these formulas that nobody believes because they don't understand, and they're not the right ones to use. [...] We got to get the math out of it and get the computing in. No calculus, start with inferential principles meets Python computing, and then they will want to do the math to prove that that works.]

> I would really love to hear a telecom engineer explain why the true origin info isn't accessible to the called person. A telephone call is a two-way connection -- the path in both directions must be known otherwise you won't have a two-way conversation.

Telephone isn't really like IP routing. If D wants to call P, the connection might get set up like this:

D -> K -> H -> V -> P

P only knows that they are speaking to V, and D only knows that they're speaking to K.

See what happens is D sends a message called "Call Request". This creates a channel id (D,C1) between D->K. K will then create it's own "Call Request" with it's own channel id (H,C2) which tells H to bill K for this call. Only K will know both the channels C1 and C2 and will bridge them internally. When H makes a "Call Request" to V, it has it's own billing arrangement with V and they agree to simply count calls, so H doesn't actually forward anything except the channel id (nil,C3). V gets away with this because the wire is clearly marked with "K TELEPHONE INC". Eventually P gets an "Incoming Call" message with it's channel id (P,C4), and can accept the call or reject it. If he accepts it, then each party will send "Accept Call" messages back down the chain.

These channel ids are used to actually carry the phone call (or data packets, or whatever).

"Caller ID" isn't the "source of the message", just some data transmitted along with the ringing sound, and as you can see the circuit doesn't have a globally unique identifier. If someone doesn't transmit who to bill, then nobody will get billed for that call (and maybe nobody will be!) but V doesn't want to send bills for this call all over the country so V only sends bills to a few carriers and its own customers.

All the bills have the "correct calling numbers on them" because of some extra billing data that's included in the call. This billing data might be omitted (the bill says "NUMBER BLOCKED"), and it clearly isn't required to establish the call. People can ask their phone company to ignore calls that have a blocked number.

Phone companies used to trust each other not to spoof this information, and now that calls from certain numbers aren't usually billed differently than from any other numbers, this doesn't cause a problem with billing -- only with people who seek to use "making a call from" an authentication method.

Sounds like an awesome job with good engineers but neglectful and irresponsible management.

If you are only making these warnings verbally, you might want to consider emailing your immediate manager with a list of concerns. Make it as neutral as possible and ask for guidance on how they want to address the issues. But if it's on the mail server, it will be good for discovery if the worst happens, and frankly given lives are at stake you probably need to show, in writing, that you were attempting to have the issues addressed.

Who knows? That might actually get traction. Might even save someone's life!

(1) "It takes a lot of speed to flip a 5,000 lbs Model S with a low center of gravity."

No it does not. Once a car is off road, on non-level ground or as in this case flying, it can roll at any speed. Push a Ferrari off a cliff and it might roll, flip and do somersaults no matter its centre of gravity.

(2) That car shows a very bad sign: impacts on both front an rear. That means multiple impacts separated by some period of time. The problem with airbags is that they can only deploy once. Same too for crumple zones. What saved these kids was most likely the seatbelts, the only safety feature that remains functional after the initial impact. This is why I am against the new trend of shock-absorbing seatbelts with stitched expansion zones, what rock climbers might call screamers. They don't work twice.

Forget the fancy safety features. The humble belt is more important than all of them put together. If you are going to roll a car, A good seat and a 5-point restraint is better than a hundred airbags.
So the difference between our opinions is basically that you think formal power is most important and informal power only a nuance to that, and I think informal power is most important and formal power only a nuance to that.

For me it's good to know that people still exist who can believe in the first. I also started out like that but the little experience I could gather from this world taught me otherwise.

I agree. The only way such a casual reaction is plausible is if they are also KGB agents.

The problem I'm having is that it doesn't really invoke any Cold War aspect any more.

They basically just are Americans, meeting with other "Americans", watching American movies or David Copperfield, visiting EPCOT or EST, alongside some rather tedious non-political espionage. They (very suddenly) don't seem to have any solid association with the Soviet Union or "the cause" any more.

The now sadly all too rare Rezidentura scenes (with some of the most interesting aspects and characters of the show IMO) and Reagan clips just seem like tacked-on lip-service to the original concept.

Dropbox's employee shuttles ran a very limited schedule and only to the Marina and Mission from their Mission Bay office. When the company was smaller it may have been more practical but over time as hiring picked up a larger percentage of employees didn't live in these two areas. Spending so much on a shrinking percentage of headcount wasn't reasonable especially since the majority of employees were paying their own commute costs, often from the South or East Bay.
Depending on the specific details of the future tech, people could be empowered, restricted, or both.

Some technologies, such as internet communication, cheap storage and sensors coupled with AI for analysis and the governmental thirst for surveillance are stacked against freedom.

On the other hand, 3d printers, solar and battery tech, promise to free small communities from economic dependence on other countries and large corporations. A small community could be almost self sufficient and thus, maybe, future people will not depend on the state so much.

So I don't think we'll get to choose what is our future, the specifics of the technologies we are going to discover will shape us, just like the internet does. To make an analogy, humans don't get to choose their walking style, but rather the human walking style is emergent from the size and shape of the body.

We don't even get to choose which domains are going to advance and which are going to stagnate. It depends on the difficulty of the discovery process. Interestingly, the rate of advancement of science and tech doesn't get perturbed even during war time. It just marches on, almost unaffected.

So, I see it like Pandora's box - it's open and we have no idea what will come out, but we're going to see a lot of it during our lifetime.

I can't help responding again. If you have tangible evidence of neglect or regulatory non-compliance, or even risks that are known about but not being dealt with by management - have you considered compiling this material and and reporting it to the FDA?

But as I've said before - I really hope you have written down your concerns to someone in management. If it gets to the point where negligence takes out the company, there's going to be an attempt to make someone a scapegoat. Depending on your role in the company you don't want to be held personally liable for the incompetence and ruthlessness of management...

To the contrary, pushing back dinner is a savvy way to serve less meals. Most employees need to get home to family or other obligations. If the food is served at 6PM then many will eat and leave, which negates the benefits of employees staying later. Serving at 7PM means serving only those that can stay later, which is likely a smaller group.
That's a bit of a stretch of the definition of employee. They sound more like freelancers, but this is why you have courts and lawyers.
I did.

You'd have to average every employee having a guest for every meal to just double meal costs. Believe that? No? Even then the above math still leaves you well shy of $25k.

How much do you think gym laundry costs? The wash & fold near me costs a couple dollars per pound. Your gym shorts, shirt, and socks do not weigh much.
As far as I can tell, this guy guessed Sydney Blumenthal's AOL account security password and got access to his AOL email account. He then saw emails from Clinton and did an IP scan on her email server. He says he has 2 gigs of data but the article doesn't make clear whether this is from Blumenthal's AOL account of Clinton's email server.

Are there anymore details? This article seems like it's dangling the word "hack" for scaremongering.
I worked on the Prop 1 campaign, and I'm not happy with this result.

At first, I thought Prop 1 would pass by a good margin, but I wasn't sure once we started hitting the outer parts of the city, where public transportation was clearly not an option. In contrast, the closer one lived to downtown, the more likely it seemed to me that they were for Prop 1. In fact, many residents in downtown don't even own a car. I felt the balance would shift on what region was more likely to go vote. Living in Austin without a car is very difficult, as the wait for a taxi can be over 30 minutes and a bus can be basically non existent. Some taxi companies only serve certain regions. Uber and Lyft usually takes five minutes.

Yes, it appeared to me that the constant barrage of flyers, canvassers, and phone calls did upset some people, and that may well have turned people away or even activated people who wouldn't have cared either way. I think that many people thought the leaving threat was a bluff and they were more than willing to call it.

In any case, I got a lot of exercise these past few weeks and got the opportunity to see many parts of this amazing city.

I'm not sure about any argument about who can or cannot write petitions. The entire point of petitions is to act as a way for the public to make a direct vote without using the proxy of representatives. Every petition is backed by money.

I hope Austin does something to improve the public transport and taxi service without sacrificing the charm of the city. Try taking a cross town bus after 10pm on a Sunday night. You won't get very far and may end up sleeping on a bench until 5:30 am. For me, this is the prevailing cost of this whole situation.

Anyways, I'm not here to debate the merits of Prop 1. Just wanted to put in my 2 cents.
So are Uber & Lyft in cahoots now?

No need to feel like there is competition when you have billions behind you (and hence a small pool of people who regularly go to lunch together?)

could you expand on in how far this is a problem? i must say i'm glad there's finally no way of talking out of it, if the data says you did it wrong, then you most likely did it wrong and the cops should make you pay money or jail time, shouldn't they? no matter whose data it was.

even if there is something like a chilling effect, if it prevents people from speeding and running red lights, that sounds pretty cool to me.

insurances are another matter. although we probably disagree over that as well, it's certainly (even) more debatable.
> If I was to setup two completely seperate Xcode environments that I needed to run at the one time I think I'd probably investigate a chroot jail.

And that's why you don't develop software for actual real human beings to use.

> I'm not following. How does having shims for git prevent this?

Because Xcode doesn't install any system components at all, the system itself provides the `xcode-select` utility that you use to select which Xcode version to use the tools from when invoking /usr/bin/git etc. If Xcode installed crap on the system, that would be impossible because each version of Xcode would have overwritten the other version's utilities. Not only that, but it would also break the ability to have 2 versions of Xcode, period, because the version that had its utilities overwritten would most likely break when the versions of the utilities change out from under it.

> I thought this was rather obvious... Apple don't want people to symlink to other applications from /usr/bin just by exporting an environment variable.

Well no, that's not the goal of SIP. SIP means nobody can muck with the system components. But the behavior you've described is the intended behavior of /usr/bin/git et al. The fact that these utilities are working as designed does not mean SIP is broken.

> You were suggesting that Linux distributions installed shims in place of where the executables are normally

No I didn't, I suggested that the fact that these shims suggest installing Command Line Tools is akin to how Linux distros often suggest installing packages via the package manager. I have no idea how you could possibly imagine I thought Linux added a shim for every single third-party utility in existence to /usr/bin. That's complete nonsense and I'm not sure how to interpret this as anything other than you insulting my intelligence.

> You haven't really given a good reason why shims are required.

I've given you multiple reasons, but you ignore most of them and suggest completely broken workarounds for the others.

If you're going to pretend that I haven't explained numerous times why it works the way it does, I don't think there's any more point in talking to you. You're too focused on your broken solution to a complete non-problem for a system you don't understand in the slightest and you obviously don't want to actually bother to learn why they work the way they do.

> You could actually run Xcode without the Xcode command line tools package

Well yes, of course you can. The fact that you think that's a surprising statement means you don't even begin to understand how Xcode works or any of the stuff I've been explaining. Please stop parading your ignorance around.
> You don't feel that a city has the right to enact an ordinance keeping black people out even if it made them feel safer (I assume)

Your example is specifically barred by the Fourteenth Amendment of the U.S. Constitution, as decided in Buchanan v. Warley, 245 U.S. 60 (1917), and Shelley v. Kraemer, 334 U.S. 1 (1948), as well as Title VIII of the Civil Rights Act of 1968, codified at 42 U.S.C. 3601-3619, aka "The Fair Housing Act"

Because it used to happen.
I'm also confused because similar legislation has passed elsewhere (like here in Australia) and Uber 'welcomed' it (in the sense that Uber was not made illegal) and continues to operate with the added sensible legislation.

Good point, Carroll distinguishes between "manifestations of the underlying laws" and the laws themselves. Still, this is an impossible claim to make, because you can't prove a negative. Given all these everyday phenomena we can't explain, it is entirely conceivable that one of them will require a modification of QFT. Personally, I think that consciousness or memory (which we all experience every day!) could rely on weaker interactions than the ones we know of. I find it unlikely but certainly possible that we aren't yet mathematically capable of predicting conscious behavior.

Isn't one of the main questions (from the IRS) regarding an employee vs contractor the substitutability of the person?

It is self-hostable already in my book (and I believe many others).

For those who think it isn't self-hostable - I'm sorry if my definition somehow doesn't fit with your world view. You are still free to use the code and make it fit in whichever definition of self-hostable you believe to be factually correct.

I presented not one, but several alternatives to hosting it, and all of them require only minor modification to the code.

I think I was clear and upfront about the benefits and limitations of this solution. Splitting hairs over self or not self hostable seems like nitpicking to me.
Yes, but these newer therapeutic uses have much lower dosing than recreational use. Recreational users take doses of about a gram or more. These thereutic doses tend to be on the order of 5 mg per kg of body weight.

(If you have any information about problems caused by long term low dosing I'd be really interested to read it).
